The mixing device for ABS resin production with a cleaning mechanism can clean the mixing tank through a cleaning component, and can clean the ABS resin attached to the inner wall of the mixing tank, so as to prevent the ABS resin remaining on the inner wall of the mixing tank from mixing into subsequent batches of resin, thereby causing impure product quality and affecting the color, transparency, mechanical properties, etc. of the final product.

[0021] The following is a detailed description of the mixing device for producing ABS resin with a cleaning mechanism. It should be noted that the description order of the following embodiments is not intended to limit the preferred order of the embodiments.

[0022] The present application is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0025] Example 2

[0026] On the basis of Example 1, the cleaning component includes: a cleaning ring 2 arranged inside the mixing tank 11, a plurality of equally distributed nozzles a21 are arranged outside the cleaning ring 2, a plurality of spacer blocks 22 are fixedly connected to the outside of the cleaning ring 2, and two arc frames 23 are respectively fixedly connected to the bottom and top of the cleaning ring 2, and a plurality of nozzles b24 are respectively arranged on the arc frames 23. A support table 4 is provided on one side of the base 1, a water tank 41 is provided on the top of the support table 4, and a pressure pump 42 is provided inside the support table 4. The air pipe of the pressure pump 42 is connected to the inside of the water tank 41, and it is characterized in that a high-pressure hose 43 is fixedly connected to one side of the water tank 41, one end of the high-pressure hose 43 passes through the connecting head 14 and is connected to the arc frame 23, and is respectively connected to a plurality of nozzles a21 and a plurality of nozzles b24.

[0027] When cleaning is needed, open the tank cover 12, disassemble and take out the stirring rod 5, and put the cleaning ring 2 into the mixing tank 11, then pull out the sealing plug of the connecting head 14, pass the high-pressure hose 43 through the connecting head 14 and connect it to the joint outside the arc frame 23, then close the tank cover 12, and start the pressure pump 42. After the pressure pump 42 is started, the compressed gas is injected into the water tank 41, and the air pressure inside the water tank 41 increases. The nozzle a21 and the nozzle b24 can be controlled separately. When the nozzle a21 is turned on, the high-pressure gas is mixed with the cleaning liquid in the water tank 41 and sprayed out. The sprayed gas-liquid mixture hits the inner wall of the mixing tank 11. The setting of the spacer block 22 leaves a flushing space between the mixing tank 11 and the cleaning ring 2, and the friction between the spacer block 22 and the mixing tank 11 can support the cleaning ring 2 when it is not cleaned, so as to prevent the cleaning ring 2 from falling directly. At the same time, open the top nozzle b24 and the top nozzle b2 After opening, the gas and liquid are sprayed out to clean the inner wall of the tank cover 12, and the gas and liquid generate a reaction force when spraying, pushing the cleaning ring 2 to move downward, and the spacer block 22 can limit the cleaning ring 2, and support it through the spacer block 22 on the side to prevent the cleaning ring 2 from tilting and turning, so that it can only move in the vertical direction, and then the cleaning ring 2 can be pushed downward continuously under the action of the thrust, so as to clean the inner wall of the mixing tank 11, and after moving to the bottom, the top nozzle b24 is closed, and the bottom nozzle b24 is opened to move the cleaning ring 2 upward, and the bottom nozzle b24 can clean the bottom of the mixing tank 11, so as to clean the mixing tank 11. When the cleaning is completed, the tank cover 12 is opened, the connection between the high-pressure hose 43 and the arc frame 23 is disconnected, and the high-pressure hose 43 is pulled out from the connector 14, and the connector 14 is sealed with a sealing block, and then the tank cover 12 is closed to make the inside of the mixing tank 11 in a sealed state.

[0028] Among them, a stirring rod 5 is provided inside the mixing tank 11, a mounting bracket 51 is fixedly connected to the top of the tank cover 12, a driving motor 52 is fixedly installed on the top of the mounting bracket 51, the drive at the bottom end of the driving motor 52 passes through the tank cover 12 and is detachably connected to the stirring rod 5, a discharge pipe 53 is provided at the bottom of the mixing tank 11, and a manual valve 54 is provided inside the discharge pipe 53.

[0029] The driving motor 52 can drive the stirring rod 5 to rotate, and the raw materials are stirred and mixed by the rotating stirring rod 5. After stirring evenly, the manual valve 54 is opened. After the manual valve 54 is opened, the discharge pipe 53 is connected. After the discharge pipe 53 is connected, the raw materials inside the mixing tank 11 are discharged outward.

[0030] Example 3

[0031] On the basis of Example 1, the feeding assembly includes: a sealing seat 3 arranged on the inner wall of the feeding barrel 13, the top of the sealing seat 3 is arranged in a V-shaped structure, and a feeding hole 31 is opened at the axis center of the sealing seat 3, a movable groove 32 is opened inside the sealing seat 3, a sealing plate 33 is slidably connected inside the movable groove 32, and a connecting rod 34 is fixedly connected to one side of the sealing plate 33, one end of the connecting rod 34 passes through the feeding barrel 13 and extends to the outside and is fixedly connected to a pull ring 35.

[0032] When adding materials, the sealing cover of the feeding barrel 13 is opened, and the raw materials to be added midway are poured into the feeding barrel 13, and then the sealing cover is closed for sealing, and the pull ring 35 is pulled outward by hand, and the sealing plate 33 is driven to move by the connecting rod 34, and the sealing plate 33 moves in the moving groove 32 until it moves out from the inside of the discharge hole 31, so that the discharge hole 31 is opened, and the V-shaped sealing seat 3 can make the raw materials gather at the discharge hole 31 and flow out quickly, and flow into the mixing tank 11 to complete the feeding, and then the pull ring 35 is pushed back to the initial position. The sealing plate 33 is driven by the connecting rod 34 to block the feed hole 31, so as to avoid a large amount of gas leakage when adding ingredients in the middle. The friction between the sealing plate 33 and the movable groove 32 can prevent the sealing plate 33 from moving along the inclination angle with the movable groove 32. During stirring, the internal air pressure of the mixing tank 11 is relatively large. At this time, there is an air pressure difference between the inside and outside of the sealing plate 303, and the sealing plate 303 is tightly attached to the movable groove 32 under the action of the air pressure difference, thereby increasing the friction between the sealing plate 33 and the movable groove 32, and also preventing the sealing plate 33 from sliding.
