Oil field three production polyacrylamide solid-liquid mixing equipment is mainly used for dry powder and water mixed homogeneous transportation. The equipment can produce high-speed mixing, grinding and dispersing, strengthening reaction, quantitative conveying and other functions in the mixing process of gouache, and can timely eliminate the agglomeration phenomenon of fish eyes and fish balls generated in the mixing process of slurry. At the same time, it realizes a multifunctional process flow of automatic adjustment of dry powder inlet, water inlet and slurry outflow and quantitative conveying when mixing dry powder and water. The equipment can automatically clean and remove the residues on the inner wall of the reaction kettle after the water powder mixing is finished by the high-pressure water pump. This high-tech multifunctional equipment is deeply welcomed by the majority of users in the polymer water powder mixing industry.

Product Principle

Main structure

The complete set of polyacrylamide solid-liquid mixing equipment for the third production of oil field is composed of spiral powder quantitative conveyor, electric knife gate, jet mixing device, high-speed homogeneous grinding device, sealed circulating cooling oil pump, etc. The spiral powder quantitative conveying device is composed of a frequency conversion motor, a reducer, a screw shaft, etc., and mainly plays the role of quantitative conveying of powder. The jet mixing device consists of a conical shell and dozens of spray heads. The jet mixing device mainly uses the water strip sprayed by high pressure to mix with the powder. The automatic rotating cleaning device is composed of an automatic rotating cleaning ball, a swirl cleaning nozzle, etc, it is mainly used to automatically rotate and clean the inner wall of the reaction kettle after the water and powder are mixed, and the cyclone cleaning nozzle performs high-pressure flushing on the inner wall of the reaction kettle to clean up the residues on the inner wall of the reaction kettle in time. The high-speed grinding homogenization pump is composed of variable frequency motor, belt drive and multi-functional rotating stator. It mainly carries out high-speed mixing, intensive grinding, grinding homogenization, quantitative transportation, etc, and can timely eliminate the slurry in the fish eye, fish and other reunion phenomenon.

Working principle

The working principle of the polyacrylamide solid-liquid mixing complete equipment in the third production of the oil field is that firstly, the polymer dry powder is quantitatively transported by adjusting the rotation speed of the spiral powder quantitative conveyor according to the flow rate of water, and enters the reactor through an electric valve. The injection device composed of dozens of injection nozzles in the reactor carries out impact mixing and homogenization on the dry powder, and then the initial mixed slurry is sucked into the grinding working chamber by the vacuum generated by the high-speed grinding homogenization pump, the special rotating stator carries out high-speed mixing of polymer slurry, grinding and dispersing, strengthening reaction, quantitative conveying and other technological processes. Under the action of centrifugal force, strong turbulence and droplet shearing are generated in the rotating stator to eliminate the agglomeration phenomenon of fish eyes and fish balls in the slurry in time. Under the control of diversified quantitative operation, the polymer solid-liquid mixer in the oil field realizes the process of automatic matching of mutual adjustment between powder inlet, water inlet and slurry outlet, timing quantitative transportation and so on. After the slurry mixing and conveying is completed, the spiral powder quantitative conveyor shall be shut down first, and then the electric valve shall be closed to prevent the water vapor from evaporating upward and contacting the polymer dry powder, which will directly affect the next work. After the electric valve is closed, the water pump can be started. Under the action of the high-pressure water pump, the automatic rotating cleaning ball sprays a strong water strip to automatically rotate and flush the reactor in all directions, so that the residue on the inner wall of the reactor continuously impacts and falls off, and then the high-pressure vortex flow generated by the swirl injection device thoroughly washes the residue on the inner wall of the reactor to ensure normal production next time.

Instructions for Use

First of all, the oil field three production polyacrylamide solid-liquid mixing equipment is installed on the dry level of the base frame, all the equipment import and export pipelines are connected by metal corrugated hose. The total power of the solid-liquid mixing reactor is ~ 10kw, and the equipment current is 380V /50Hz /3P. Among them, the high-speed grinding homogenization pump is a frequency conversion 7.5kw two-pole motor, the spiral powder quantitative conveyor is a 0.37 frequency conversion reduction motor, the circulating oil pump motor is 0.4kw, and the oil pump lubricating oil is 32#-46# hydraulic lubricating oil, up to the intermediate value of the oil standard. After wiring, check the running direction of the oil pump. After the lubricating oil circulates normally, jog the high-speed grinding homogenization pump. Please mark the steering of all motors according to the motor steering. In order to ensure the long-term normal operation of the high-speed grinding homogenization pump, the circulating lubricating oil pump in the sealing chamber is turned on and on. The water can only be fed after the high-speed grinding homogenization pump is started and operated normally. The mixed slurry flow rate produced by the high-speed grinding homogenization pump must match the water inflow and powder inflow. However, it should be considered that the water inflow is less than the pulp outflow when matching. The rotating speed of the screw powder quantitative conveyor is adjusted according to the water intake, so as to achieve the quantitative mixing and homogeneous conveying of water powder. At the end of the work, first close the spiral powder quantitative conveyor, then close the electric valve, and then open the cleaning water pump, by the automatic rotating cleaning ball and spiral cleaning device at the same time to clean the inner wall of the reaction kettle, after the completion of cleaning and then close the high-speed grinding homogenization pump, and finally cut off the total power supply.

Note: The user provides relevant parameters of material characteristics, or brings materials to the production base for on-site testing, and the manufacturer selects the internal structure of the grinding disc according to the characteristics of the medium.
