[0004] To achieve the above purpose, the specific technical solution of the utility model is as follows:

[0005] A polymer powder impurity magnetic separation device includes: a conveying component: a chain plate conveyor belt that can be switched between a magnetic or non-magnetic state or a partially magnetic and partially non-magnetic state; a suction component: arranged at the rear section of the conveying direction of the chain plate conveyor belt, having a suction piece for sucking and collecting powder and a storage box for storing the sucked powder, the suction direction of the suction piece matches the conveying surface of the chain plate conveyor belt; a feeding funnel: arranged at the front section of the conveying direction of the chain plate conveyor belt, the interior is hollow to form a feeding channel, and the feeding channel gradually shrinks along the falling direction of the powder to form a feeding port. Through such a design, the powder is evenly fed to the chain plate conveyor belt through the feeding funnel, and the chain plate conveyor belt transports the powder to the suction position of the suction piece. At this time, the chain plate conveyor belt at the suction position has magnetism to absorb iron filings in the powder, so that the suction piece sucks away the powder and leaves the iron filings, thereby removing iron impurities in the powder.

[0006] Furthermore, the chain plate type conveyor belt comprises a plurality of chain plates, and the chain plates comprise an electromagnet and a shell covering the electromagnet. Through such a design, when the electromagnet is powered on, a magnetic field is generated to absorb iron filings, and when the electromagnet is powered off, the magnetic field disappears and no iron filings are absorbed.

The sensing detection plate is arranged at each of the two corners of the chain plate conveyor belt, and the sensing detection plate is matched with the sensing direction of the distance sensor. Through such a design, the preset distance sensor controls the electromagnet in the chain plate to open or close when detecting a certain length of distance, and then sets the sensing detection plate at a reasonable position to measure the shortest distance between the distance sensor and the sensing detection plate, and uses the shortest distance as the switching distance of the distance sensor.

[0008] Furthermore, the suction and collection component includes a blower, a blower air inlet pipe, a cyclone dust collection bucket and an air suction pipe, one end of the blower air inlet pipe is connected to the air inlet part of the blower, the other end is inserted from the top of the cyclone dust collection bucket and extends to the side position near the bottom of the cyclone dust collection bucket, one end of the air suction pipe is connected to the upper half of the side wall of the cyclone dust collection bucket in the height direction, and the other end cooperates with the material conveying surface of the chain plate conveyor belt to absorb and collect powder, and the open end of the cyclone dust collection bucket is connected to the material storage box. Through such a design, the space inside the cyclone dust collection bucket and the material storage box is in a sealed state. When the blower air inlet pipe is evacuated, the gas can only enter from the air suction pipe, so that the air suction pipe generates suction to absorb and collect powder, and the airflow carrying the powder into the cyclone dust collection bucket will spiral downward along the inner wall of the bucket and gather to the open end. After the powder gathers at the open end, it falls into the material storage box due to gravity.

[0010] Furthermore, the material storage box includes a box body and a material storage drawer, the material storage drawer is detachably connected to the box body, a sealing gasket is provided at the joint between the material storage drawer and the side wall of the box body, and the material storage drawer is provided with a handle. With such a design, it is more convenient for staff to take away the processed powder.

[0011] Furthermore, the feeding funnel includes a bracket and a funnel body, and the bracket sets the funnel body above the chain plate conveyor belt.

[0012] Furthermore, it also includes a mounting base, the mounting base includes a first step surface and a second step surface, the second step surface is higher than the first step surface, the second step surface is used to support the suction component, the first step surface is arranged below the chain plate conveyor belt, and the first step surface is detachably provided with a magnetic plate. With such a design, when the chain plate conveyor belt moves to the downward position, the electromagnet is turned off, and the iron filings and impurities adhering to the chain plate are transferred by the magnetic field of the magnetic plate, thereby playing the role of cleaning the chain plate conveyor belt.

[0013] Furthermore, the conveying assembly also includes supporting legs, and the supporting legs are used to support the chain plate conveyor belt.

[0014] The beneficial effects of the utility model are as follows: powder is evenly fed onto the chain plate conveyor belt through the feeding funnel, and the chain plate conveyor belt transports the powder to the suction position of the suction collecting part. At this time, the chain plate conveyor belt located at the suction position has magnetism to absorb iron filings in the powder, so that the suction collecting part absorbs the powder and leaves the iron filings, thereby removing iron impurities in the powder.

The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. Instead, they are merely examples of devices and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0027] like Figures 1 to 10 shown.

[0028] Example 1

[0029] A device for magnetic separation of polymer powder impurities comprises: a conveying component: provided with a chain plate conveyor belt 1 which can be switched between a magnetic or non-magnetic state or a partially magnetic and partially non-magnetic state; a suction component: arranged at the rear section of the chain plate conveyor belt 1 in the material transport direction, having a suction collecting member 2 for collecting powder and a storage box 3 for storing the collected powder, the suction direction of the suction collecting member 2 matches the material transporting surface of the chain plate conveyor belt 1; a feeding funnel 4: arranged at the front section of the chain plate conveyor belt 1 in the material transport direction, the interior of which is hollow to form a feeding channel 5, and the feeding channel 5 gradually shrinks along the falling direction of the powder to form a feeding port 6.

[0030] The chain plate conveyor belt 1 includes a plurality of chain plates 7 , and the chain plates 7 include an electromagnet 8 and a shell 9 covering the electromagnet 8 .

[0031] The conveying assembly also includes a sensing detection plate 11 and a distance sensor 10 fixedly arranged on the chain plate 7. The sensing detection plate 11 is arranged at each of the two corner positions of the chain plate conveyor belt 1. The sensing detection plate 11 matches the sensing direction of the distance sensor 10.

[0032] The suction and collection component 2 includes a blower 12, a blower air inlet pipe 13, a cyclone dust collecting barrel 14 and an air suction pipe 15. One end of the blower air inlet pipe 13 is connected to the air inlet part of the blower 12, and the other end is inserted from the top of the cyclone dust collecting barrel 14 and extends to a position near the bottom of the cyclone dust collecting barrel 14. One end of the air suction pipe 15 is connected to the upper half of the side wall of the cyclone dust collecting barrel 14 in the height direction, and the other end cooperates with the material conveying surface of the chain plate conveyor belt 1 to absorb and collect powder. The open end of the cyclone dust collecting barrel 14 is connected to the storage box 3.

[0033] The feeding funnel 4 includes a bracket and a funnel body, and the bracket sets the funnel body above the chain plate conveyor belt 1.

[0034] It also includes a mounting base 24, which includes a first step surface 25 and a second step surface 26, wherein the second step surface 26 is higher than the first step surface 25, and the second step surface 26 is used to support the suction component, and the first step surface 25 is arranged below the chain plate conveyor belt 1, and the first step surface 25 is detachably provided with a magnetic plate 27.

[0035] The conveying assembly further comprises a supporting leg 28 , and the supporting leg 28 is used to support the chain conveyor belt 1 .

[0036] The implementation method of the above embodiment is as follows: the staff adds the powder into the feeding funnel 4, and the powder falls to the chain plate conveyor 1 through the feeding channel 5. Since the chain plate conveyor 1 is always in a uniform speed operation, the powder will be laid on the chain plate conveyor 1 in a thin layer. When the chain plate conveyor 1 transports the powder to the suction pipe 15 of the suction component, the suction pipe 15 sucks the powder away by suction. At this time, the electromagnet 8 of the chain plate conveyor 1 is in the open state, and the iron filings impurities are adsorbed on the chain plate 7. The suction pipe 15 sucks away the powder and leaves the iron filings. The powder enters the cyclone dust collecting barrel 14 from the air inlet pipe and spirally rotates downward along the inner wall of the barrel and gathers to the open end. After gathering to the open end, it falls into the storage box 3 by gravity.

[0037] The chain plate conveyor belt 1 continues to operate carrying iron filings impurities. When the distance sensor 10 detects the sensing detection plate 11 at the corner where the chain plate 7 is flipped from top to bottom, the distance sensor 10 controls the electromagnet 8 inside the chain plate 7 to turn off. The chain plate 7 no longer absorbs iron filings. The iron filings fall due to gravity, and some of the iron filings adhered to the chain plate 7 are affected by the magnetic force of the magnetic plate 27 and are absorbed by the magnetic plate 27. The chain plate 7 continues to operate until the distance sensor 10 detects the sensing detection plate 11 at the corner where the chain plate 7 is flipped from bottom to top. The distance sensor 10 controls the electromagnet 8 to turn on for the next round of iron filing removal.

[0040] The implementation of the above embodiment is as follows:

[0041] The sum of the apertures of the plurality of suction holes 19 is smaller than the diameter of the suction pipe 15 , and the diversion chamber 17 can distribute the suction force of the suction pipe 15 to each suction hole 19 , thereby dispersing the suction force of the suction pipe 15 and preventing the suction pipe 15 from being unable to absorb powder at the side of the chain plate conveyor belt 1 .
