Description

Technical Field

[0001] This utility model relates to the field of spray filter technology, and in particular to a vacuum electrostatic spray filter based on corrosion protection enhancement. Background Technology

[0002] The filtration mechanism of a filter is that when gas containing dust (or solid particles) passes through the filter media layer, only the gas or liquid is allowed to pass through, while the solid is trapped on the surface of the filter media.

[0003] Application No. 202223384540.3 discloses an electrostatic spraying powder recovery and filtration device. This device uses agitation of the filter plates to clear accumulated powder from the filter pores, thus aiding in filtration and preventing clogging and improving efficiency. However, since the negative pressure pump used for suction is typically located at the end of the filter, powder particles tend to adhere to each transition plate under negative pressure. Simply agitating the filter plates is insufficient to prevent clogging. Utility Model Content

[0004] This utility model discloses a vacuum electrostatic spray filter based on corrosion resistance enhancement, which aims to solve the technical problem that powder particles will be adsorbed on each transition plate under negative pressure suction, and simply shaking cannot effectively prevent the filter pores from being blocked.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A corrosion-resistant vacuum electrostatic spraying filter includes an outer shell, and further includes: a base fixedly connected to the bottom outer wall of the outer shell; a negative pressure unit fixedly connected to the bottom inner wall of the outer shell; multiple filter plates fixedly connected to the inner wall of the outer shell, each filter plate having a symmetrically fixedly connected feeding bend pipe to its bottom inner wall, and the aperture of the multiple filter plates decreasing from top to bottom; a cleaning mechanism connected to the outer shell; and a feeding mechanism connected to one side outer wall of the outer shell.

[0007] The cleaning mechanism includes: multiple square grooves symmetrically arranged on the inner walls of opposite sides of the outer casing; multiple U-shaped supports, each with a magnetic slider I fixedly connected to both ends, and the magnetic slider I movably connected to the square grooves; multiple scrapers movably attached to the top of each filter plate, and fixedly connected to the bottom outer wall of the U-shaped supports; multiple transverse electric guide rails fixedly connected to the outer walls of both sides of the outer casing, and each transverse electric guide rail has a carriage movably connected to it; and multiple magnetic sliders II fixedly connected to the outer walls of the multiple carriages, the multiple magnetic sliders II movably attached to the outer wall of the outer casing, and magnetically attracted to the magnetic slider I through the outer casing.

[0008] By incorporating a cleaning mechanism, the slide is driven to move horizontally via a horizontal electric guide rail. The magnetic slider two, which moves horizontally, magnetically attracts the magnetic slider one, causing the U-shaped bracket and scraper to move back and forth to clean the top of each filter plate. This ensures the removal of adsorbed particles while maintaining airtightness, preventing multiple filter plates from becoming clogged and affecting filtration efficiency.

[0009] In a preferred embodiment, the feeding mechanism includes: multiple external guide tubes fixedly connected to the inner walls of both sides of the outer casing; two crossbars with sliders fixedly connected to both ends; and multiple longitudinal electric guide rails fixedly connected to the top outer wall of the base, with multiple sliders correspondingly movably connected to the longitudinal electric guide rails.

[0010] The feeding mechanism further includes: multiple inserts fixedly connected to the bottom outer wall of the cross frame, and multiple insert plates fixedly connected to the inner wall of each insert; multiple feeding bends symmetrically fixedly connected to the bottom inner wall of each filter plate, and multiple inserts movably fitting against the tail ends of the multiple feeding bends.

[0011] The feeding mechanism further includes: multiple through slots, which are disposed through the inner wall of the top of each feeding bend, and multiple insert plates are respectively inserted into the multiple through slots; multiple sliding grooves, which are disposed through the inner wall of the outer casing, and a crossbeam is movably inserted into the sliding groove.

[0012] With a feeding mechanism, during the filtration process, multiple scrapers reciprocate, pushing the filtered particles from the top of each filter plate into the feeding bends on both sides. The reciprocating longitudinal movement of the insert and the insert plate ensures a relatively sealed environment inside the outer casing while preventing excessive particle accumulation in the feeding bends, which could affect subsequent filtration efficiency.

[0013] In a preferred embodiment, the top inner wall of the outer shell is fixedly connected to a feed inlet, and a sealing ring 1 is fixedly wrapped around the outside of the feed inlet. The bottom inner wall of the outer shell is fixedly connected to a sealing ring 2, and the sealing ring 2 is located at the connection between the negative pressure machine and the outer shell. Both the sealing ring 1 and the sealing ring 2 are made of fluororubber.

[0014] The outer shell includes: a base layer, which is made of 316L stainless steel; and an adhesive layer, which is fixedly attached to the top outer wall of the base layer and is a chromium-rich oxide film.

[0015] The outer shell further includes: a transition layer, fixedly attached to the top outer wall of the adhesive layer, which is a Cr3C2-NiCr coating; a functional layer, fixedly attached to the top outer wall of the transition layer, which is a suspended PTFE resin; and a protective layer, fixedly attached to the top outer wall of the functional layer, which is made of siloxane resin.

[0016] Since ordinary filters corrode more quickly in a vacuum environment, affecting their service life, this filter is designed with a base layer, adhesive layer, transition layer, functional layer, and protective layer. Since both sealing ring one and sealing ring two are made of fluororubber, the corrosion resistance of the seals can be enhanced, thus ensuring the filter's corrosion resistance in a vacuum environment.

[0017] As described above, a corrosion-resistant vacuum electrostatic spraying filter includes an outer shell and further comprises: a base fixedly connected to the bottom outer wall of the outer shell; a negative pressure unit fixedly connected to the bottom inner wall of the outer shell; multiple filter plates fixedly connected to the inner wall of the outer shell, each filter plate having a symmetrically fixedly connected feeding bend pipe to its bottom inner wall, and the aperture of the multiple filter plates decreasing from top to bottom; a cleaning mechanism connected to the outer shell; and a feeding mechanism connected to one side outer wall of the outer shell. The cleaning mechanism includes: multiple square grooves symmetrically arranged on opposite sides of the outer shell. The filter comprises: an inner side wall; multiple U-shaped supports, each with a magnetic slider fixedly connected to both ends, and the magnetic sliders movably connected to a corresponding square groove; multiple scrapers movably attached to the top of each filter plate and fixedly connected to the bottom outer wall of the U-shaped supports; multiple transverse electric guide rails fixedly connected to the two outer walls of the outer casing, with a carriage movably connected to each transverse electric guide rail; and multiple magnetic sliders fixedly connected to the outer walls of the carriages, movably attached to the outer wall of the outer casing, and magnetically attracted to the magnetic sliders through the outer casing. This utility model provides a corrosion-resistant vacuum electrostatic spray filter that, while ensuring sealing, removes adsorbed particles and prevents multiple filter plates from becoming clogged, thus improving filtration efficiency.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] The present invention discloses a vacuum electrostatic spraying filter based on corrosion resistance enhancement, which is mainly used in electrostatic spraying filtration scenarios.

[0025] Reference Figure 1 and Figure 2 A vacuum electrostatic spraying filter with improved corrosion resistance includes a housing 4, and further includes: a base 6 fixedly connected to the bottom outer wall of the housing 4; a negative pressure unit 7 fixedly connected to the bottom inner wall of the housing 4; multiple filter plates 8 fixedly connected to the inner wall of the housing 4, each filter plate 8 having a symmetrically fixedly connected feeding bend 101 to its bottom inner wall, and the aperture of the multiple filter plates 8 decreasing from top to bottom; a cleaning mechanism 5 connected to the housing 4; and a feeding mechanism 1 connected to one side outer wall of the housing 4.

[0026] The cleaning mechanism 5 includes: multiple square grooves 501 symmetrically arranged on the inner walls of opposite sides of the outer casing 4; multiple U-shaped brackets 503, each with a magnetic slider 502 fixedly connected to both ends, and the magnetic sliders 502 movably connected to the square grooves 501; multiple scrapers 504 movably attached to the top of each filter plate 8, and fixedly connected to the bottom outer wall of the U-shaped brackets 503; multiple transverse electric guide rails 505 fixedly connected to the outer walls of both sides of the outer casing 4, and each transverse electric guide rail 505 movably connected to a carriage 506; and multiple magnetic sliders 507 fixedly connected to the outer walls of the multiple carriages 506. Multiple magnetic sliders 507 are movably attached to the outer wall of the outer shell 4, and are magnetically attracted to the magnetic slider 502 through the outer shell 4. The wall thickness is reduced by the square groove 501. The slide 506 is driven to move horizontally by the horizontal electric guide rail 505. The magnetic sliders 507 and 502 are magnetically attracted to each other, which drives the U-shaped bracket 503 and scraper 504 to move back and forth, scraping off the particles adsorbed and isolated at the top of multiple filter plates 8 and pushing them to both ends, and entering the feeding mechanism 1 for temporary storage. In this way, the adsorbed particles can be removed while ensuring the sealing, and the multiple filter plates 8 can be blocked to avoid affecting the filtration efficiency.

[0027] Reference Figure 2 In a preferred embodiment, the top inner wall of the outer shell 4 is fixedly connected to the feed inlet 3, and the feed inlet 3 is fixedly wrapped with a sealing ring 2. The bottom inner wall of the outer shell 4 is fixedly connected to a sealing ring 9, and the sealing ring 9 is located at the connection between the negative pressure machine 7 and the outer shell 4. Both the sealing ring 2 and the sealing ring 9 are made of fluororubber.

[0028] Reference Figure 4 In a preferred embodiment, the outer shell 4 includes: a base layer 401, which is made of 316L stainless steel; and an adhesive layer 402, which is fixedly attached to the top outer wall of the base layer 401 and is a chromium-rich oxide film.

[0029] Reference Figure 4In a preferred embodiment, the outer casing 4 further includes: a transition layer 403, fixedly attached to the top outer wall of the adhesive layer 402, which is a Cr3C2-NiCr coating; a functional layer 404, fixedly attached to the top outer wall of the transition layer 403, which is a suspended PTFE resin; and a protective layer 405, fixedly attached to the top outer wall of the functional layer 404, which is made of siloxane resin. Since ordinary filters will corrode more quickly in a vacuum environment, affecting their service life, by setting up a base layer 401, an adhesive layer 402, a transition layer 403, a functional layer 404, and a protective layer 405, the adhesive layer 402 is used to enhance the tightness of the connection, the transition layer 403 is used to alleviate the difference in thermal expansion coefficients between the substrate and the functional layer, the functional layer 404 is used to achieve dual characteristics of corrosion resistance and functionality, and the protective layer 405 is used to provide an ultimate protective barrier. Furthermore, since the sealing ring 2 and the sealing ring 9 are also made of fluororubber, the corrosion resistance of the seals can be enhanced, thereby ensuring the corrosion resistance of the filter in a vacuum environment.

[0030] Reference Figure 3 In a preferred embodiment, the feeding mechanism 1 includes: a plurality of external guide tubes 106, which are fixedly connected to the inner walls of both sides of the outer casing 4; two crossbars 109, with sliders 105 fixedly connected to both ends; a plurality of longitudinal electric guide rails 104, which are fixedly connected to the top outer wall of the base 6, and the plurality of sliders 105 are correspondingly movably connected to the longitudinal electric guide rails 104.

[0031] Reference Figure 3 In a preferred embodiment, the feeding mechanism 1 further includes: a plurality of inserts 107 fixedly connected to the bottom outer wall of the cross frame 109, and a plurality of insert plates 108 fixedly connected to the inner wall of each insert 107; a plurality of feeding bends 101 symmetrically fixedly connected to the bottom inner wall of each filter plate 8, and the plurality of inserts 107 movably fitting against the tail ends of the plurality of feeding bends 101.

[0032] Reference Figure 3In a preferred embodiment, the feeding mechanism 1 further includes: a plurality of through slots 102, which are disposed through the inner wall of the top end of each feeding bend 101, and a plurality of insert plates 108 are respectively inserted into the plurality of through slots 102; a plurality of sliding grooves 103, which are disposed through the inner wall of the outer casing 4, and a crossbeam 109 is movably inserted into the sliding groove 103. During the filtration process, when the plurality of scrapers 504 reciprocate, they push the filtered particles at the top of each filter plate 8 into the feeding bends 101 on both sides. At this time, the insert bracket 107 is movably attached to the tail of the feeding bend 101. The end is sealed to intercept particles in each feed bend 101. After a certain period of time, the crossbeam 109 is moved down by the longitudinal electric guide rail 104, and the insert 107 is disengaged from the tail end of the feed bend 101. At the same time, the insert plate 108 is inserted through the through groove 102 to establish a partition inside each feed bend 101. Particles remaining at the tail end of the open feed bend 101 are discharged by the external guide pipe 106. Under this structure, the relatively sealed environment inside the outer shell 4 can be guaranteed, while avoiding excessive accumulation of particles in the feed bend 101, which would affect the subsequent filtration efficiency.

[0033] Working principle: The wall thickness is reduced by setting the square groove 501. The slide 506 is driven to move horizontally by the horizontal electric guide rail 505. The magnetic slider 2 507 and magnetic slider 1 502 are magnetically attracted to each other, which drives the U-shaped bracket 503 and scraper 504 to move back and forth. The particles adsorbed and isolated on the top of multiple filter plates 8 are scraped off and pushed to both ends and enter the feeding mechanism 1 for temporary storage. In this way, the adsorbed particles can be removed while ensuring the sealing, and the multiple filter plates 8 are prevented from being blocked and affecting the filtration efficiency.

[0034] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
