Explosive shear crushing pump

Overview The shear crushing pump is a wet shear crushing pump specially developed by Nantong Fleck Company for the existence of many non-factors in the crushing process of explosive solid materials. The main structure of the equipment is the application of a number of Nantong Fulek Company's patented technology [patent number ZL201821463410X, ZL2018211533889, ZL2014105300958], has been in Oktojin, black gold, red phosphorus, perforating charges, sulfur and other easily explosive solid materials in the wet crushing process has been applied. Shear crushing pump is a kind of wet shear, dispersion emulsification, grinding, mixing and transportation as one of the multi-functional equipment, the equipment in the easy explosive wet crushing has reliable sex and stability, by the majority of users of the pro-gaze. Maintenance of shear crushing pump The shear crushing pump shall be installed on a relatively flat and horizontal cement ground. Four pieces of shockproof rubber pads of about 10mm shall be installed between the bases of the ground equipment. Then four M16 upping screws of the bottom feet shall be tightened. When wiring, the standard copper core three-phase four-wire shall be used according to the rated current of 22kw motor. When starting the motor, check first: ① whether the mechanical hydraulic lubricating oil in the bearing seat can see the oil line in the middle of the oil mark; ②, open the water seal water inlet pipe, a small amount of water can overflow from the outlet of the water pipe; ③, before starting the motor, check the steering of the motor and whether there is abnormal noise in the pump body, and start the motor officially after confirming that it is correct. When maintaining the equipment, first unscrew the handwheel and then open the housing feed sheet cover, flush the rotating stator of the working chamber with a water gun, especially the two screw holes in the middle of the rotor, which must be washed clean. Under the condition that there is no material residue, unscrew the compression nut of the rotor with a wrench, and take the rotor and water-sealed copper sleeve with a special tool. If there is water leakage between the housing and the bearing seat, the skeleton seal at the rear end of the water seal is broken. When replacing, unscrew the screw behind the housing, then take out the housing and take out the skeleton seal. At this time, the bearing can also be replaced. When replacing the stator, unscrew the four external screws on the feed cover plate.

FLEK slurry transfer pump

FLK-JLS type Fulack slurry pump is a kind of high viscosity and contains a large number of sizes of slurry extrusion shear conveying. The material contact part of the flake slurry conveying pump is made of high-quality stainless steel, and the feeding waist wheel part is made of high-quality gray cast iron HT300. At present, the flake slurry conveying pump is widely used for fully enclosed pipeline conveying of various slurries containing a large number of particles such as ore slurry, fish, crab, shrimp, shellfish, etc.

Rubber asphalt mixer

The rubber asphalt mixer is a combination of a cone screw mixer and a single-shaft knife mixer. Mainly used for rubber powder and asphalt in mixing will not produce rubber powder suspension, powder, agglomeration and other phenomena, and more effective to reduce the flying of dust, shorten the rubber powder and asphalt mixing time, so that the rubber powder or additives more quickly and effectively evenly distributed in the asphalt.

Gas-liquid enhanced reactor

Gas-liquid enhanced reactor is a reaction device that can strengthen the transfer process and micro-mixing process, mainly used for gas-liquid-solid multi-phase materials without gravity mixing, enhanced reaction and other process, mainly including interphase mass transfer, carbonization reaction and crystallization. Due to the fast chemical reaction rate, the process of gas absorption and solid dissolution is the control step of the process, and the gas absorption is the main control step of the whole process. The traditional bubble carbonization method and spray method make the product have some problems, such as insufficient ultrafine particle size, wide particle size distribution and difficult control, long carbonization reaction time and so on. Therefore, the gas-liquid enhanced reactor manufactured by Nantong Fulek fundamentally strengthens the transfer process and micro-mixing process in the reactor. Such as calcium carbonate, basic magnesium sulfate whiskers and so on.

Graphene production complete equipment

The general situation of graphene production equipment At present, the preparation methods of graphene production are mainly mechanical method, oxidation method, substrate growth method and liquid phase method, etc. Most of these production technologies and methods have disadvantages such as low yield, high energy consumption and poor quality, thus stopping the production and development of graphene in China. After unremitting efforts, Nantong Fulack Graphene Production Research Group has invented a graphene production line that integrates high-speed dispersion, crushing and grinding, vortex cavitation and shear ultrasound, which directly disperses graphite sheets continuously in liquid phase and continuously peels off graphite sheets. It has realized the production of high-quality graphene through mechanical shearing, hydraulic cavitation and other technical means, which is favored by the majority of graphene manufacturers. Graphene production equipment is a high-tech advanced equipment that uses mechanical hydraulic shearing and cavitation to peel off graphite sheets to produce high-quality graphene such as single-layer and multi-layer. The invention and application of this advanced technology has accelerated the pace of graphene production to a certain extent, and also promoted the confidence of graphene manufacturers to carry out large-scale, high-efficiency, low-cost, and pollution-free production. Moreover, this production process of mechanical hydraulic shearing and cavitation vortex stripping graphite sheet has the characteristics of simple operation, safety and reliability, no oxidation, no high temperature, and high quality products, which is very suitable for large-scale production of high-quality graphene. Graphene production equipment process flow graphene production process flow: first, graphite powder, dispersant or surface modifier and water are mixed in a high-shear dispersion mixing batching tank for dispersion and stirring, first close the circulation valve and then open the connecting valve between the storage tank and the dispersion grinding pump, so that graphite solution enters the high-shear cyclone ultrasonic accumulator through a fine dispersion grinding mill and a hydraulic shear vortex cavitator and then enters the process of high-shear cyclone ultrasonic accumulator through pressure. When there is no material in the batching tank, the lower connecting valve will be automatically closed and the circulating valve will be opened to allow the graphite solution to continuously circulate and peel off the sheets so that the graphene single layer and multi-layer can achieve the desired effect. The pressure control, time control and temperature control designed in the integrated control system can also be controlled by computer or touch frequency control or full-automatic control.

High Shear Dispersion Microemulsification Machine

High-shear dispersion microemulsification machine is a new type of dispersion emulsification technology, and it is also an indispensable dispersion microemulsification equipment in the fine emulsification industry. In production, Fulake high-shear dispersion microemulsifiers are generally used in combination with vertical emulsifiers. Vertical emulsifiers produce large droplet diameter, poor dispersion effect, uneven mixing, easy stratification and other shortcomings when stirring liquid-liquid and liquid-solid. These common problems Fulake high-shear dispersion microemulsifiers can solve this problem. Under the drive of the motor, the Flecker high-shear dispersion micro-machine re-disperses and emulsifies the coarsely mixed material mixture. Under the action of centrifugal force and mechanical movement, the material mixture moves in a high-speed curve in the tooth groove of the rotating stator and bears tens of millions of times per minute of high-speed shearing, extrusion collision, severe friction, etc., forming strong hydraulic force and turbulence, and ultrasonic wave generated in gradient extrusion oscillation, the excellent effect of droplet size up to 0.3 microns is achieved in the cyclic movement of more than 100,000 times, such as elongation, deformation and shearing of water droplets, and the best state of uniform distribution, mutual stability and long-term non-stratification.
