Description

Technical Field

[0001] The invention relates to the field of magnet processing, and in particular to a dust removal device for magnet processing. Background Art

[0002] During the production and processing of existing magnets, a large amount of dust and magnetic powder are often generated. The existing dust removal is often done by suction through magnet blocks, but the dust cannot be removed, and the magnetic powder mixed with dust cannot be recycled and is prone to cause pollution.

[0003] Therefore, there is a dust removal device for magnet processing with patent number CN219253524U. While solving the above problems, it has the following defects, such as: when the scraper scrapes off the magnetic powder on the outer wall of the magnetic cylinder during rotation, it is well known that since the magnetic powder is adsorbed on the magnetic cylinder, the scraper can only block the magnetic powder on the outer wall of the magnetic cylinder to prevent it from continuing to rotate with the magnetic cylinder. At this time, a large amount of magnetic powder will be adsorbed and accumulated upstream of the scraper due to the influence of the scraper. Under the influence of the suction force, the magnetic powder will not fall from the top of the magnetic cylinder in large quantities, which will affect the cleaning efficiency of the magnetic powder adsorbed on the magnetic cylinder. At the same time, it cannot fully make the gas contact with the magnetic cylinder to remove the magnetic powder mixed therein. Summary of the invention

[0004] The object of the present invention is to provide a dust removal device for magnet processing.

[0005] The technical problem of the present invention is mainly solved by the following technical solutions:

[0006] A dust removal device for magnet processing, comprising a box, wherein a magnetic cylinder driven by a motor 1 is arranged in the box:

[0007] A grid plate is suspended on the top wall of the box body to separate it into a spray chamber and an adsorption chamber, wherein an air outlet pipe is arranged on the top of the spray chamber, and a spray assembly is arranged in the spray chamber, the magnetic cylinder is arranged in the adsorption chamber, wherein an arc-shaped plate buckled on the magnetic cylinder is arranged in the adsorption chamber, and one end of the arc-shaped plate is connected to the grid plate, a gas flow channel is constructed between the arc-shaped plate and the magnetic cylinder, wherein a plurality of groups of flow guide mechanisms are arranged in the gas flow channel, and a baffle plate for blocking the opening of the gas flow channel is arranged in the adsorption chamber away from the grid plate, and an air inlet pipe extending into the gas flow channel is arranged above the baffle plate;

[0008] The outer wall of the magnetic tube is axially provided with multiple groups of slots for accommodating arc-shaped plastic plates, wherein two groups of vertical plates are also provided at the bottom of the box body directly below the magnetic tube, and the tops of the vertical plates close to the baffle are closely attached to the outer wall of the magnetic tube.

[0009] Preferably, the outlet end of the air inlet pipe is bent upward.

[0010] Preferably, the distance between one end of the baffle and the outer wall of the magnetic tube is no more than 0.6 cm, wherein a sponge strip in contact with the outer wall of the magnetic tube is bonded to the bottom of the end of the baffle.

[0011] Preferably, two groups of vertical plates divide the inner bottom of the box into a temporary storage chamber, a separation chamber and a liquid storage chamber in sequence, wherein the temporary storage chamber is arranged on the same side as the baffle, a drainage pipe is arranged at the bottom of the liquid storage chamber, and the bottom end of the grid plate is lower than the horizontal plane of the top end of the vertical plate.

[0015] The beneficial effects of the present invention are as follows: the present invention introduces the gas containing dust and magnetic powder into the gas circulation channel through the air inlet pipe, wherein the gas flows clockwise in the gas circulation channel, and the motor I drives the magnetic cylinder to rotate counterclockwise, so that the gas in the gas circulation channel fully contacts the outer wall of the magnetic cylinder, and then the magnetic powder contained in the gas is adsorbed on the outer wall of the magnetic cylinder, so as to achieve the purpose of removing the magnetic powder in the gas; when the magnetic powder adsorbed on the surface of the magnetic cylinder moves to the top of the left vertical plate as the magnetic cylinder rotates, the vertical plate will scrape off the magnetic powder on the outer wall of the magnetic cylinder to prevent it from continuing to rotate downward with the magnetic cylinder, but instead make a large amount of magnetic powder adhere to the outer wall of the magnetic cylinder upstream of the vertical plate; when the magnetic cylinder drives the plastic plate to rotate to the vertical plate, the plastic plate does not have magnetism and will not adsorb the magnetic powder. At this time, the accumulated magnetic powder located upstream of the vertical plate will inevitably fall into the temporary storage chamber in large quantities after encountering the plastic plate, so as to achieve the purpose of quickly cleaning the magnetic powder on the outer wall of the magnetic cylinder.

DETAILED DESCRIPTION

[0018] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0019] A dust removal device for magnet processing, comprising a box body 1, wherein a magnetic cylinder 2 driven by a motor 1 is arranged in the box body 1:

[0020] A grid plate 103 is suspended on the top wall of the box body 1 to separate it into a spray chamber 101 and an adsorption chamber 102, wherein an air outlet pipe 3 is arranged at the top of the spray chamber 101, and a spray assembly 4 is arranged in the spray chamber 101, and the spray assembly 4 includes spray pipes arranged vertically and crosswise, wherein the spray pipes are connected to the water reservoir through pipes, and a water pump is arranged on the pipes, and a nozzle is arranged at the bottom of the spray pipes;

[0021] The magnetic tube 2 is arranged in the adsorption chamber 102, wherein the adsorption chamber 102 is provided with an arc plate 5 buckled on the magnetic tube 2, and one end of the arc plate 5 is connected to the grid plate 103, and a gas flow channel 6 is formed between the arc plate 5 and the magnetic tube 2, wherein a plurality of groups of flow guide mechanisms 7 are arranged in the gas flow channel 6, and a baffle 8 for blocking the opening of the gas flow channel 6 is arranged in the adsorption chamber 102 away from the grid plate 103, and an air inlet pipe 9 extending into the gas flow channel 6 is arranged above the baffle 8, wherein the outlet end of the air inlet pipe 9 is bent upward;

[0022] The outer wall of the magnetic tube 2 is axially provided with a plurality of slots for accommodating the arc-shaped plastic plates 10 , wherein two sets of vertical plates 11 are also provided at the bottom of the box body 1 directly below the magnetic tube 2 , and the top ends of the vertical plates 11 close to the baffle 8 are tightly attached to the outer wall of the magnetic tube 2 .

[0023] like Figure 1As shown, the distance between one end of the baffle 8 and the outer wall of the magnetic tube 2 is not more than 0.6 cm, wherein a sponge strip 12 is bonded to the bottom of the end of the baffle 8 and is in contact with the outer wall of the magnetic tube 2. Since there is a large gap between the baffle 8 and the outer wall of the magnetic tube 2, the magnetic tube 2 can drive the magnetic powder adsorbed on its outer wall to slide through the above gap during the rotation process, and the magnetic powder will not be scraped off by the end of the baffle 8 during this process. When the adsorbed magnetic powder slides through the above gap, the sponge strip 12 can be squeezed to deform, and finally the magnetic powder slides through the above gap along with the rotating magnetic tube 2. The sponge strip 12 is provided for the purpose of facilitating the magnetic tube 2 to drive the magnetic powder to slide through, and secondly, to maximize the prevention of the gas in the gas guide channel 6 from flowing out through the above gap.

[0024] like Figure 1 As shown, two groups of vertical plates 11 divide the bottom of the box body 1 into a temporary storage chamber 13, a separation chamber 14 and a liquid storage chamber 15 in sequence, wherein the temporary storage chamber 13 is arranged on the same side as the baffle 9, a drainage pipe is arranged at the bottom of the liquid storage chamber 15, and the bottom end of the grid plate 103 is lower than the top horizontal plane of the vertical plate 11.

[0025] In this embodiment, the flow guide mechanism 7 includes a screw 71 parallel to the magnetic tube 2, wherein a screw hole screwed to the screw 71 is opened on the side wall of the box body 1, and a flow guide plate 72 tangentially arranged to the magnetic tube 2 is radially arranged on the outer wall of the screw 71 in the box body 1.

[0026] like Figure 1 As shown, the screw 71 can be rotated on the outside of the box body 1 to rotate in the screw hole, thereby driving the guide plate 72 to rotate, so as to change the distance between its end and the outer wall of the magnetic tube 2, and then guide the air flow to the outer wall of the magnetic tube 2, so that the magnetic powder in the gas is fully in contact with the outer wall of the magnetic tube 2. Of course, after the guide plate 72 rotates, its two ends will not be against the inner wall of the box body 1, so that there is a movable gap between the two ends of the guide plate 72 and the side wall of the box body 1.

[0027] In this embodiment, a knocking mechanism 16 is provided in the box body 1 and is located outside the arc plate 5, wherein the knocking mechanism 16 includes a rotating shaft 161 driven by a motor II, and a metal ball 162 is fixed to the rotating shaft 161 through a connecting rod. When a lot of dust may adhere to the inner wall of the arc plate 5 after a certain period of use, the rotating shaft 161 is driven by the motor II to swing back and forth, so as to drive the metal ball 162 to knock the outer wall of the arc plate 5, thereby shaking off the dust on the inner wall of the arc plate 5, so that the dust is shaken off and flows out together with the gas in the gas flow channel 6.

[0028] The method of use of the present invention: Figure 1As shown, the gas containing dust and magnetic powder is introduced into the gas flow channel 6 through the air inlet pipe 9, wherein the gas flows clockwise in the gas flow channel 6, and the motor 1 drives the magnetic cylinder 2 to rotate counterclockwise, so that the gas in the gas flow channel 6 is fully in contact with the outer wall of the magnetic cylinder 2, and then the magnetic powder contained in the gas is adsorbed on the outer wall of the magnetic cylinder 2, so as to achieve the purpose of removing the magnetic powder in the gas;

[0029] When the magnetic powder adsorbed on the surface of the magnetic tube 2 moves to the top of the left vertical plate 11 as the magnetic tube 2 rotates, the vertical plate 11 will scrape off the magnetic powder on the outer wall of the magnetic tube 2 to prevent it from continuing to rotate downward with the magnetic tube 2, but make a large amount of magnetic powder adhere to the outer wall of the magnetic tube 2 upstream of the vertical plate 11. When the magnetic tube 2 drives the plastic plate 10 to rotate to the vertical plate 11, the plastic plate 10 does not have magnetism and will not adsorb the magnetic powder. At this time, the accumulated magnetic powder located upstream of the vertical plate 11 will inevitably fall into the temporary storage chamber 13 in large quantities after encountering the plastic plate 10, so as to achieve the purpose of quickly cleaning the magnetic powder on the outer wall of the magnetic tube 2.

[0030] When the dust-containing gas flows out through the right opening of the gas circulation channel 6, it will enter the spray chamber 101 through the bottom of the grid plate 103. At this time, the water mist sprayed by the spray component 4 can spray and wash the gas, thereby removing the dust in the gas. The washed gas is discharged through the outlet pipe 3, and the washing liquid falls into the liquid storage chamber 15. When the liquid level in the liquid storage chamber 15 is high, it is discharged through the water outlet pipe to prevent it from overflowing the top of the vertical plate 11.

[0031] The present invention is described in detail above, but the contents are only preferred embodiments of the present invention and cannot be considered to limit the scope of implementation of the present invention. All equivalent changes and improvements made according to the scope of application of the present invention should still fall within the scope of the patent coverage of the present invention.
