Description

Technical Field

[0001] This application relates to the field of screening device technology, and in particular to a magnetic rotary screen. Background Technology

[0002] Grinding mills are key equipment in complete powder coating production lines. They are widely used in the grinding and processing of mineral materials in metallurgy, building materials, chemical industry, mining and other fields. Powder coatings are solid powder synthetic resin coatings composed of solid resin, pigments, fillers and additives. The processing steps require cutting the formed material into pieces, grinding the pieces with a grinding mill, screening them and then packaging them. In addition, insulating powder coatings cannot contain metal particles in order to prevent the coating from being broken down by electric current.

[0003] In the existing technology, during the daily operation of the grinding mill, a certain amount of metallic iron particles are usually generated due to wear between the various structures of the equipment. These metallic iron particles will mix into the powder coating, causing the powder coating to fail to achieve the expected insulation effect, resulting in poor preparation efficiency of insulating powder coating and increased production costs. Utility Model Content

[0004] This invention provides a magnetic rotary sieve, which effectively improves the preparation efficiency of insulating powder coatings and reduces preparation costs during the powder coating preparation process.

[0013] In some alternative embodiments, the T-shaped limiting block includes a card and a locking post connected to the card, wherein the E side of the card always abuts against the F side of the limiting hole, and the locking post moves freely inside the limiting hole.

[0014] In some alternative embodiments, the hollow base is circular; each magnetic component is arranged in a circular array at equal intervals on the hollow base with the center of the hollow base as the center.

[0015] The magnetic rotary screen provided in this application is not only suitable for screening iron particles in the screening process of insulating powder coatings, but also for screening iron particles in the screening process of other non-ferrous powder materials.

[0037] refer to Figure 1 , Figure 1 This is a three-dimensional schematic diagram of a magnetic rotary screen according to this application. Figure 1 As shown, a magnetic rotary screen includes a screen body 10, a rotary screen device 30 disposed inside the screen body 10, and a magnetic suction device 20 disposed inside the screen body 10; the magnetic suction device 20 is located at the lower part of the rotary screen device 30; here, in the production process of powder coating, its raw materials are first screened by the rotary screen device 30, and the material after the initial screening passes through the area of ​​the magnetic suction device 20 to remove iron particles from the material.

[0038] refer to Figure 2 , Figure 2 This is a three-dimensional schematic diagram of the magnetic suction device 20 in a magnetic rotary screen according to this application. Figure 2As shown, the magnetic attraction device 20 includes a hollow base 21 and a magnetic attraction mechanism 22 connected to the hollow base 21. The hollow base 21 is in the shape of a ring, and the magnetic attraction mechanism 22 includes at least four magnetic attraction components 221. Each magnetic attraction component 221 is arranged in a circular array at equal intervals on the hollow base 21 with the center of the hollow base 21 as the center.

[0039] Here, a magnetic attraction mechanism 22 is connected to the hollow base 21 so that the material after passing through the crushing device 31 and the rotary screen device 30 in the process of preparing powder coating can enter the next process through the hollow base 21 after the iron particles in it are attracted by the magnetic attraction mechanism 22.

[0040] refer to Figure 3 , Figure 3 This is a schematic cross-sectional view of the magnetic suction component 221 in a magnetic rotary screen according to this application. Figure 3 As shown, the magnetic assembly 221 includes a support rod 222 and a soft cloth magnetic strip 223 covering the support rod 222. The soft cloth magnetic strip 223 is dustproof and waterproof, and can adapt to the support rod 222 of round, square and irregularly shaped columns.

[0041] Here, by setting a magnetic suction device 20 inside the sieve body 10, the magnetic suction mechanism 22 in the magnetic suction device 20 is connected to the hollow base 21, the magnetic suction components 221 in the magnetic suction mechanism 22 are evenly arrayed on the hollow base 21, and the soft cloth magnetic array 223 in the magnetic suction component 221 covers the outside of the support rod 222. The magnetic plates 225 in the soft cloth magnetic array 223 are evenly distributed on its soft cloth 224. At the same time, the rotary sieve device 30 inside the sieve body 10 is located above the magnetic suction device 20, so that after the material passes through the rotary sieve device 30, the magnetic suction device 20 adsorbs the iron particles in the material. Then, the material without iron particles passes through the hollow base 21 and enters the next process. Therefore, in the powder coating preparation process, the preparation efficiency of insulating powder coating is effectively improved and the preparation cost is reduced.

[0042] refer to Figure 4 and Figure 5 , Figure 4 This is a three-dimensional schematic diagram of the soft cloth magnetic array 223 in a magnetic rotary screen according to this application. Figure 5 yes Figure 4 An enlarged view of circle A shown. Figure 4 and Figure 5 As shown, the soft cloth magnetic strip 223 includes a soft cloth 224 and magnetic plates 225 evenly distributed on the soft cloth 224; the soft cloth 224 is provided with first hook and loop fasteners 2241 on opposite sides of both ends, and second hook and loop fasteners 2242 are also evenly distributed on the soft cloth 224.

[0043] Here, the magnetic plates 225 distributed on the soft cloth 224 can adsorb iron particles in the material from multiple angles, enhancing the magnetic attraction mechanism 22's ability to attract iron particles and improving the preparation efficiency of the insulating powder coating. In addition, the soft cloth 224 has first Velcro 2241 on opposite sides at both ends, so that after the soft cloth magnetic array 223 is wrapped around the support rod 222, its free end can be tightly wrapped around the support rod 222 through the first Velcro 2241 at both ends of the soft cloth 224, effectively improving the convenience of operation.

[0044] refer to Figure 6 , Figure 6 This is a three-dimensional schematic diagram of the magnetic plate 225 in a magnetic rotary screen according to this application. Figure 6 As shown, the magnetic plate 225 includes a hinged housing 2251 and a magnetic block 2252 disposed inside the hinged housing 2251. Here, the shape of the magnetic block 2252 is adapted to the cavity shape of the hinged housing 2251, and the housing is set to be hinged so that when the amount of iron particles adsorbed by the magnetic block 2252 reaches the maximum, it is necessary to remove the magnetic block 2252 for cleaning, or when a new magnetic block 2252 needs to be replaced, the magnetic block 2252 can be quickly disassembled and installed, effectively improving work efficiency.

[0045] refer to Figure 7 and Figure 8 , Figure 7 This is an exploded view of the opening and closing carrier shell 2251 in a magnetic rotary screen according to this application. Figure 8 This is a schematic diagram of the opening and closing carrier shell 2251 in a magnetic rotary screen according to another perspective of this application. Figure 7 and Figure 8 As shown, the foldable carrier shell 2251 includes a first carrier shell 2253 and a second carrier shell 2254. The first carrier shell 2253 has a locking head 2257 on its C end, and the second carrier shell 2254 has a locking groove 2258 on its outer side. The locking groove 2258 cooperates with the locking head 2257 to realize the connection between the first carrier shell 2253 and the second carrier shell 2254. The first carrier shell 2253 also has a third Velcro 2255 on its outer side. The third Velcro 2255 cooperates with the second Velcro 2242 to realize the connection between the first carrier shell 2253 and the soft cloth 224. The locking head 2257 has a limiting hole 2257A in the middle position, and the locking groove 2258 has a T-shaped limiting block 2258A inside. The T-shaped limiting block 2258A cooperates with the limiting hole 2257A.

[0046] Here, the locking head 2257 is an elastic locking head. During the interaction between the locking head 2257 of the first carrier shell 2253 and the locking slot 2258 of the second carrier shell 2254, after the locking head 2257 moves to the position of the locking slot 2258, it expands using its own elasticity and automatically engages with the locking slot 2258. During the opening of the first carrier shell 2253 and the second carrier shell 2254, the operator can manually press the elastic position of the locking head 2257 to cause it to contract, thereby separating the locking head 2257 from the locking slot 2258. In addition, the second Velcro 2242 engages with the third Velcro 2255 on the first carrier shell 2253, and the second carrier shell 2254 is in a free state, so that the operator can touch the locking head 2257 and press it.

[0047] refer to Figure 9 , Figure 9 This is a schematic cross-sectional view of the T-shaped limiting block 2258A in a magnetic rotary screen according to this application. Figure 9 As shown, the T-shaped limiting block 2258A includes a card 2258A1 and a locking post 2258A2 connected to the card 2258A1. The E side of the card 2258A1 always abuts against the F side of the limiting hole 2257A. The locking post 2258A2 moves freely inside the limiting hole 2257A to limit the position of the card head 2257 by the card slot 2258 when the card slot 2258 and the card head 2257 are not in a locked state. This allows the second carrier shell 2254 to restrict the position of the first carrier shell 2258 when the first carrier shell 2253 and the second carrier shell 2254 are separated. The limitation at position 253 prevents the first carrier shell 2253 from falling off, improves the convenience of operation, and prevents loss. That is to say, when the opening and closing carrier shell 2251 is opened, the first carrier shell 2253 and the second carrier shell 2254 are separated. However, under the action of the T-shaped limiting block 2258A and the limiting hole 2257A, the card head 2257 and the card slot 2258 are not separated. At the same time, the E side of the card 2258A1 always abuts against the F side of the limiting hole 2257A, which effectively improves the stability of the connection between the first carrier shell 2253 and the second carrier shell 2254.

[0048] To facilitate understanding, the working principle of this application is further described as follows: In the process of using the magnetic rotary screen, the material passes through the crushing device 31 and the rotary screen device 30 in succession, and then reaches the magnetic attraction area of ​​the magnetic attraction device 20. The material after passing through the magnetic attraction area is the material without iron particles. Then the material enters the next process through the hollow base 21.

[0049] In addition, when it is necessary to disassemble and install the soft cloth magnetic strip 223 on the support rod 222, the operator can do so by directly separating or attaching the first Velcro 2241 on opposite sides of the soft cloth 224.

[0050] In addition, when it is necessary to remove the magnetic plate 225 from the soft cloth magnetic strip 223, the operator can directly press the soft cloth 224 and pull the magnetic plate 225 until the magnetic plate 225 is separated from the soft cloth 224; if it is necessary to install the magnetic plate 225, the second hook and loop fastener 2242 can be aligned with the third hook and loop fastener 2255, and the magnetic plate 225 can be pressed to make the magnetic plate 225 stably connected to the soft cloth 224.

[0051] Meanwhile, if it is necessary to replace the magnetic block 2252, the operator can locate the elastic position of the locking head 2257 and press it inward, causing the locking head 2257 to retract. At the same time, the first carrier shell 2253 and the second carrier shell 2254 are pulled in opposite directions until the magnetic block 2252 is loosened and can be removed for cleaning or replacement. After cleaning or replacement, a clean magnetic block 2252 or a new magnetic block 2252 can be placed between the first carrier shell 2253 and the second carrier shell 2254. The operator pushes the first carrier shell 2253 and the second carrier shell 2254 in opposite directions, causing the locking head 2257 to expand and its elastic position to move into the slot 2258, so that the locking head 2257 and the slot 2258 are engaged, thus completing the installation of the magnetic block 2252.
