[0002] Polyethylene (PE for short) is a thermoplastic resin obtained by polymerization of ethylene monomer. In industry, it also includes copolymers of ethylene and a small amount of a-olefins. Polyethylene is odorless, non-toxic, feels like wax, and has excellent low-temperature resistance (the lowest operating temperature can reach -100 to -70°C). It has good chemical stability because the polymer molecules are connected by carbon-carbon single bonds and can withstand the corrosion of most acids and alkalis (not resistant to oxidizing acids). It is insoluble in general solvents at room temperature, has low water absorption, and has excellent electrical insulation. During the production of PE, its main materials and auxiliary materials need to be transported to a mixing device for mixing, so as to obtain raw materials for the production of thermoplastic resins with various properties. At present, the auxiliary materials for PE production are all put into the mixing device through a suction and delivery device to deliver the specified amount of auxiliary materials.

[0003] Since there are usually a lot of production raw materials in the mixing device, putting all the auxiliary materials into the mixing device at one time will cause the auxiliary materials to diffuse and stir and mix in the raw materials in the mixing device.

DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0023] Reference Figure 1-2 , an auxiliary material suction and distribution device for PE production, comprises a workbench 1, a support plate 2 is fixedly arranged on the workbench 1, a mixing tank body 3 is fixedly arranged on the support plate 2, a plurality of support plates 2 are arranged, the top of the support plate 2 is arc-shaped, the arc at the top of the support plate 2 is clamped on the outer wall of the mixing tank body 3, a raw material tank 4 and an auxiliary material tank 5 are arranged in sequence above the mixing tank body 3, and an equal amount of suction and distribution components are arranged between the mixing tank body 3 and the auxiliary material tank 5.

[0024] like Figure 3-5As shown, the equal amount suction distribution assembly includes a first connecting pipe 6 fixedly arranged on the mixing tank body 3, an equal amount distribution cylinder 7 is fixedly arranged on the top of the first connecting pipe 6, a distribution column 8 is rotatably arranged in the equal amount distribution cylinder 7, a distribution slot 9 is provided on the distribution column 8, a fixed plate 10 is fixedly arranged at one end of the equal amount distribution cylinder 7, and one end of the fixed plate 10 is connected to the mixing tank body 3. A driven disk 11 is rotatably arranged on the fixed plate 10, the driven disk 11 is docked with the distribution column 8 in the equal amount distribution cylinder 7, a matching slot 12 is provided on the driven disk 11, and a clamping slot 13 is provided between two adjacent matching slots 12, an active disk 14 is provided below the driven disk 11, the active disk 14 is rotatably connected to the fixed plate 10, the active disk 14 is clamped in the matching slot 12 on the driven disk 11, and a clamping block 15 is fixedly arranged on the active disk 14. The fixed plate 10 is fixedly provided with a protective shell 16, and the protective shell 16 covers the driven disk 11 and the active disk 14 therein, and a servo motor 17 is fixedly provided on the protective shell 16, and the output end of the servo motor 17 is connected to the active disk 14, and a second connecting pipe 18 is fixedly provided on the equal-volume dispensing cylinder 7. A suction pump 19 is provided between the second connecting pipe 18 and the auxiliary material tank 5, and the liquid extraction port and the liquid outlet of the suction pump 19 are connected to the auxiliary material tank 5 and the second connecting pipe 18 respectively.

[0025] Among them, the diameter of the distribution column 8 is adapted to the inner diameter of the equal-amount distribution cylinder 7, so that the auxiliary material delivered to the distribution slot 9 will not flow into the adjacent distribution slot 9 through the gap between the distribution column 8 and the equal-amount distribution cylinder 7, thereby causing the distribution slot 9 to deliver the auxiliary material inaccurately; the diameter of the clamping block 15 is adapted to the size of the clamping slot 13, so that the clamping block 15 is clamped in the clamping slot 13 to drive the driven disk 11 to rotate, and the rotation of the driven disk 11 will not be frustrated due to the gap between the clamping block 15 and the clamping slot 13.

[0026] In this example, when it is necessary to transport the auxiliary material in the auxiliary material tank 5 to the mixing tank body 3, the suction pump 19 and the servo motor 17 are started. The start of the suction pump 19 will extract the auxiliary material in the mixing tank body 3 and transport it to the second connecting pipe 18. The start of the servo motor 17 drives the active disk 14 to rotate. When the engaging block 15 on the active disk 14 rotates into the engaging groove 13 on the driven disk 11, the driven disk 11 rotates. The rotation of the driven disk 11 drives the delivery column 8 to rotate. When the engaging block 15 on the active disk 14 rotates out of the engaging groove 13 on the driven disk 11, the delivery groove 9 on the delivery column 8 is located at the second connecting pipe 18. Directly below, the auxiliary material in the second connecting pipe 18 will be transported to the distribution slot 9 on the distribution column 8, and the distribution slot 9 will be filled with auxiliary materials. When the engaging block 15 on the active disk 14 rotates to the engaging slot 13 on the driven disk 11, the driven disk 11 continues to drive the distribution column 8 to rotate. When the distribution slot 9 filled with auxiliary materials rotates to the first connecting pipe 6, the auxiliary materials in the distribution slot 9 will be distributed to the mixing tank body 3. The auxiliary materials falling into the mixing tank body 3 will be quickly mixed with the raw materials in the mixing tank body 3. The above method is repeated to add auxiliary materials to the mixing tank body 3 for multiple times until the specified amount of auxiliary materials is completely added to the mixing tank body 3.

[0027] By setting up the equal amount suction and delivery component, the equal amount of auxiliary materials can be intermittently and continuously delivered to the mixing tank body 3. This not only makes the amount of auxiliary materials added to the mixing tank body 3 the same, thereby facilitating the control of the amount of auxiliary materials added to the mixing tank body 3, but also the multiple equal amounts of auxiliary materials delivered can improve the mixing effect of the auxiliary materials and the raw materials in the mixing tank body 3. In addition, it can also reduce the mixing time of the raw materials and auxiliary materials in the mixing tank body 3, thereby improving the mixing efficiency of the raw materials and auxiliary materials in the mixing tank body 3.

The first connecting plate, the second connecting plate, and the connecting bolts make it easy and convenient to disassemble and install the raw material tank 4 and the mixing tank body 3, and the connection between the raw material tank 4 and the mixing tank body 3 is firm.

[0029] A feeding pipe 21 is fixedly provided at the top of the raw material tank 4 and the auxiliary material tank 5, a driver 22 is fixedly provided at one end of the mixing tank body 3, a stirring and mixing assembly is provided in the mixing tank body 3 (based on the existing technology, the present invention will not describe it in detail), and the output end of the driver 22 is connected to the stirring and mixing assembly in the mixing tank body 3.
