[0002] At present, in the chip spinning production workshop, the chip is conveyed to the crystallization bed and then to the drying tower, and a large amount of dust is inevitably generated due to friction, crystallization and drying. Once the chip is mixed with dust, it will be different from the normal drying chip in the melting process due to its physical form and composition, forming abnormal conditions such as degradation, liquefaction and carbonization, which are not conducive to production stability and seriously affect product quality. Based on the above situation, a dust removal device that can conveniently and effectively affect the production process is needed. SUMMARY

[0003] In order to solve the technical problems existing in the prior art, the purpose of the present application is to provide a drying chip dust removal device, which can solve the dust generated by conveying, friction, crystallization and drying, thereby ensuring product quality and production stability.

[0004] To solve the above-mentioned technical problems, the present application adopts the following technical scheme:

[0005] A drying chip dust removal device, comprising a rectangular cuboid bin, a feed inlet arranged above the rectangular cuboid bin, a discharge outlet arranged below the rectangular cuboid bin, a first filter screen and a second filter screen arranged in the rectangular cuboid bin, and a partition plate, wherein the first filter screen, the partition plate and the side surface of the rectangular cuboid bin combine to form a first filtering cavity, the second filter screen and the side surface of the rectangular cuboid bin combine to form a second filtering cavity, one side of the first filtering cavity and the second filtering cavity is provided with a dust suction pipe, and the chip dust entering the rectangular cuboid bin can be filtered by the first filter screen and the second filter screen and then discharged by the dust suction pipe.

[0006] Preferably, the first filter screen is arranged downwardly inclined, the partition plate is arranged upwardly inclined, the first filtering cavity is a triangular cavity structure, and the feed inlet is arranged above the first filter screen.

[0007] The first filter screen arranged downwardly inclined can make the dust and other small particles in the material pass through the filter hole, while the large particles of the drying chip continue to fall downward along the first filter screen, avoiding the accumulation of the drying chip. The partition plate is arranged upwardly inclined, the first filtering cavity is a triangular cavity structure, the dust filtered by the first filter screen is collected uniformly by the partition plate and then accumulated together, facilitating the suction of the dust.

[0008] Preferably, the discharge port is arranged below the partition plate, and the lower side of the second filter screen is arranged at one side of the discharge port.

[0009] The second filter screen can perform secondary filtration on the dried slice filtered by the first filter screen, so that the dried slice contains less dust, and the dried slice can be quickly discharged from the discharge port through the second filter screen, so that the material at the discharge port is prevented from being retained for a long time.

[0010] Preferably, the front surface of the cuboid bin is provided with a detachable panel.

[0011] After the panel is opened, the inside can be conveniently temporarily overhauled or the material is conveniently handled.

[0012] Preferably, the panel is provided with three visual mirrors.

[0013] The visual mirror can conveniently observe the flow of the dried slice in the cuboid bin at any time.

[0014] Compared with the prior art, the beneficial effects of the present application are as follows:

[0015] After the dust removal device is installed on the discharge pipeline of the drying tower, the material enters the cuboid bin, and when the material contacts the first filter screen and the second filter screen, the dust inevitably generated due to friction, crystallization and drying can fall into the first filter cavity and the second filter cavity and be discharged outward through the dust suction pipe at one side, so that the slice after removing most of the dust can be discharged through the discharge port for melting and feeding, and the dried slice after dust filtration can ensure stable production and eliminate safety accidents caused by dust accumulation.
