Description

Technical Field

[0001] The utility model relates to the technical field of discharging of a mixer for MPP pipe production, in particular to a discharging pipe of a mixer for MPP cable protection pipe production. Background Art

[0002] The raw material of the MPP cable protection pipe is plastic particles. After being mixed by a mixer, the plastic particles are conveyed to an extruder. The extruder shears and heats the particles into a molten state. The raw materials in the molten state enter the die head through a diverter plate with a structure of multiple small holes.

[0003] Most of the impurities in the raw materials (plastic particles) are crushed or decomposed in the extruder. However, during the transportation, production or stirring of the raw materials, magnetic materials such as iron slag and damaged gaskets may be mixed in. These impurities are relatively hard. On the one hand, they will scratch the screw of the extruder. On the other hand, they will block the diverter plate, preventing the raw materials from entering the die head evenly, resulting in the inability to guarantee the product size. More seriously, it will increase the equipment load, damage the equipment and affect the service life of the equipment.

[0004] Chinese Patent CN201855733U discloses a device for removing magnetic metal impurities in powder materials. A rotary magnetic filter is arranged in the blanking pipe of this patent to adsorb magnetic metal impurities in the powder. The defect of this structure is that the rotary magnetic filter requires an additional drive motor, with high energy consumption, and it is inconvenient to clean the magnetic metal impurities adsorbed on the rotary magnetic filter. Content of the Utility Model

[0005] The purpose of the utility model is to provide a discharging pipe of a mixer for MPP cable protection pipe production.

[0006] The innovation point of the utility model is that: in this application, a strong magnetic block is used to make the iron ring carry strong magnetism, which can adsorb magnetic materials in plastic particles; a drainage cone is set, and partition bars are set on the drainage cone. Drainage grooves are formed between adjacent partition bars to form drainage and diversion of plastic particles, so that the plastic particles can evenly contact the inner wall of the iron ring, and the magnetic materials mixed in the plastic particles can be better adsorbed.

[0007] To achieve the above-mentioned utility model purpose, the technical solution of the utility model is:

[0008] A discharge pipe of a mixer for producing MPP cable protection tubes comprises a pipe body, wherein the pipe body is divided into an upper drainage section and a lower adsorption section; a drainage cone with a smaller upper portion and a larger lower portion coaxial with the drainage section is arranged in the center thereof, the side wall of the drainage cone is arc-shaped, and the drainage cone is connected to the side wall of the drainage section by a bracket; an iron ring with a hollow structure is arranged on the inner wall of the adsorption section, the outer wall of the iron ring is fitted with the inner wall of the adsorption section, a plurality of strong magnetic blocks are evenly distributed on the outer wall of the adsorption section along the circumferential direction, and the strong magnetic blocks, the adsorption section and the iron ring are fixed by bolts.

[0009] Furthermore, a plurality of partition strips are evenly spaced along the circumferential direction on the side wall of the drainage cone, and drainage grooves are formed between adjacent partition strips.

[0010] Furthermore, the top of the iron ring is higher than the bottom of the drainage cone; the top of the iron ring is a slope sloping downward.

[0011] Furthermore, the number of the strong magnetic blocks is 6 to 12.

[0012] The beneficial effects of the utility model are:

[0013] First: The strong magnetic block magnetizes the iron ring so that the iron ring as a whole carries strong magnetism, which can effectively adsorb the magnetic materials mixed in the plastic particles.

[0014] Second: Set up a drainage cone to drain the plastic particles, so that more plastic particles can contact the inner wall of the iron ring, and then impurities such as magnetic materials mixed in the particles can be better adsorbed.

[0015] Third: Setting partitions on the drainage cone can, on the one hand, better divert the flow, and on the other hand, slow down the falling speed of particles, so that impurities such as magnetic materials can be better adsorbed.

[0016] Fourth: The strong magnetic block, the iron ring and the adsorption section are connected by bolts. On the one hand, it is convenient to replace the strong magnetic block, and on the other hand, the magnetic material adsorbed on the inner wall of the iron ring can be cleaned without disassembly.
