Description

Technical Field

[0001] This invention belongs to the field of high-salinity wastewater treatment technology, specifically a filtration device for treating high-salinity industrial wastewater. Background Technology

[0002] Currently, a large amount of high-salt wastewater is generated during the steel smelting process. In order to avoid environmental pollution caused by the direct discharge of high-salt wastewater and to achieve the recycling of water resources, a series of treatments such as filtration, flocculation and separation are required for high-salt wastewater.

[0003] In existing technologies, the filtration of high-salinity wastewater is mostly achieved using filter plates. Wastewater passes through the filter plate, which intercepts impurities, separating the wastewater from the impurities. To prevent excessive accumulation of impurities on the filter plate surface and subsequent clogging, existing technologies typically include a scraping mechanism. While the filter plate is filtering the wastewater, this mechanism removes the impurities intercepted on its surface, thus preventing clogging. However, as wastewater passes through the filter plate, some impurities on the surface can easily enter the filter pores due to the impact of the wastewater. These impurities become stuck inside the pores, and when the scraping mechanism tries to remove them, these stuck impurities are difficult to clean effectively. This results in poor clogging prevention and affects the wastewater filtration efficiency. Summary of the Invention

[0004] In view of the shortcomings of the prior art, the technical problem to be solved by the embodiments of the present invention is to provide a filtration device for treating high-salt industrial wastewater.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0006] A filtration device for treating high-salinity industrial wastewater includes a filter box, a filter plate, a first drive assembly, a cleaning assembly, a second drive assembly, and a scraper frame.

[0007] The filter plate is fixedly installed inside the filter box, and several filter holes are opened on both the left and right sides of the filter plate.

[0008] The scraper frame is located on the upper part of the filter plate.

[0009] The first drive assembly is mounted on the side wall of the filter box and is used to drive the scraper frame to move back and forth along the upper part of the filter plate to scrape the debris stuck on the upper part of the filter plate to the edge of the filter plate.

[0010] The cleaning assembly is movably positioned at the bottom center of the filter plate.

[0011] The second drive assembly is located on the side of the filter plate. When the scraper frame moves back and forth, the second drive assembly drives the cleaning assembly to rotate back and forth. When the cleaning assembly rotates back and forth, it cleans the debris in the filter holes to the upper part of the filter plate.

[0012] As a further improvement of the present invention: the first driving assembly includes a motor, a lead screw, a second guide rod, a first slider, and a second slider.

[0013] Both the first slider and the second slider are fixedly installed on the upper part of the scraper frame. The motor is fixedly installed on the side wall of the filter box. One end of the lead screw is connected to the output end of the motor, and the other end passes through the second slider and is threadedly engaged with the second slider. The second guide rod is fixedly installed on the inner wall of the filter box. The second guide rod passes through the first slider and is movably engaged with the first slider.

[0014] As a further improvement of the present invention: the hole cleaning assembly includes a support plate,

[0015] One end of the support plate is hinged to the middle of the bottom of the filter plate. Several push rods are fixedly provided on both sides of the support plate. Several push rods on one side of the support plate correspond one-to-one with several filter holes on the right side of the filter plate, and several push rods on the other side of the support plate correspond one-to-one with several filter holes on the left side of the filter plate.

[0016] As a further improvement of the present invention: two sets of sliding grooves are provided on the side wall of the filter box, one set of sliding grooves being located above the filter plate and the other set of sliding grooves being located below the filter plate.

[0017] The second drive assembly includes a U-shaped connecting rod and a pusher wheel. One end of the U-shaped connecting rod extends from one set of the sliding grooves to the top of the filter plate and is fixedly connected to the scraper frame. The other end extends from another set of the sliding grooves to the bottom of the filter plate and is rotatably connected to the pusher wheel.

[0018] As a further improvement of the present invention: a first guide rod is fixedly provided at the middle position of the bottom of the filter plate, a limit end block is fixedly provided at the bottom of the first guide rod, a slide plate is slidably provided on the first guide rod, a pin is fixedly provided at the bottom of the slide plate, a rotating plate is fixedly provided at the end of the support plate, the rotating plate is rotatably engaged with the pin, and push strips are fixedly provided on both opposite sides of the support plate, and the end of the push strip is provided with an inclined surface.

[0019] As a further improvement of the present invention: a drain outlet is provided on the lower part of the side wall of the filter box.

[0020] As a further improvement of the present invention: a cleaning port is provided on the side wall of the filter box at the upper part of the filter plate, and a sealing door is movably provided in the cleaning port.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] In this embodiment of the invention, when high-salt industrial wastewater needs to be filtered, the wastewater can be introduced into the area above the filter plate. After entering the filter plate, the wastewater passes through several filter holes and falls to the bottom of the filter box. Impurities in the wastewater are intercepted on the upper part of the filter plate, thus achieving wastewater filtration. During this process, the first driving component drives the scraper frame to move back and forth along the upper part of the filter plate. As the scraper frame moves back and forth, it scrapes the impurities retained on the upper part of the filter plate to the edge of the filter plate, removing them from above the filter holes and preventing them from clogging the filter holes and affecting the subsequent filtration effect of the wastewater. Since some impurities on the surface of the filter plate are easily flushed into the filter holes by the wastewater when it passes through the filter holes, causing further clogging, to avoid this phenomenon, while the scraper frame moves back and forth along the upper part of the filter plate, the second driving component drives the cleaning component. The cleaning assembly rotates left and right. When it rotates to the left, it cleans the filter holes on the left side of the filter plate, moving debris clogging the left filter holes to the upper part of the filter plate. Combined with the leftward movement of the scraper frame, smaller debris, along with debris remaining on the upper part of the filter plate, is scraped to the left edge of the filter plate. Similarly, when it rotates to the right, it cleans the filter holes on the right side of the filter plate, moving debris clogging the right filter holes to the upper part of the filter plate. Combined with the rightward movement of the scraper frame, debris, along with debris remaining on the upper part of the filter plate, is scraped to the right edge of the filter plate. Compared to existing technologies, when filtering high-salt industrial wastewater, this assembly not only automatically cleans debris directly retained on the upper part of the filter plate but also automatically cleans debris clogging inside the filter holes, thereby improving the cleaning effect, enhancing the anti-clogging effect of the filter holes, and effectively ensuring the filtration efficiency of the wastewater.

Detailed Implementation

[0030] The technical solution of the present invention will be further described in detail below with reference to specific embodiments.

[0031] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0032] Please see Figure 1 as well as Figure 2This embodiment provides a filtration device for treating high-salt industrial wastewater, including a filter box 10, a filter plate 20, a first drive assembly 30, a cleaning assembly 40, a second drive assembly 50, and a scraper frame 60. The filter plate 20 is fixedly installed inside the filter box 10, and a plurality of filter holes 201 are formed on both the left and right sides of the filter plate 20. The scraper frame 60 is disposed on the upper part of the filter plate 20. The first drive assembly 30 is installed on the side wall of the filter box 10 and is used to drive the scraper frame 60 along the filter plate 20. The upper part of the filter plate 20 moves back and forth to scrape the debris stuck on the upper part of the filter plate 20 to the edge of the filter plate 20. The cleaning hole assembly 40 is movably disposed at the middle position of the bottom of the filter plate 20. The second drive assembly 50 is disposed on the side of the filter plate 20. When the scraping frame 60 moves back and forth, the second drive assembly 50 drives the cleaning hole assembly 40 to rotate back and forth. When the cleaning hole assembly 40 rotates back and forth, it cleans the debris in several filter holes 201 to the upper part of the filter plate 20.

[0033] When high-salinity industrial wastewater needs to be filtered, the wastewater can be introduced into the area above the filter plate 20. After entering the filter plate 20, the wastewater passes through several filter holes 201 and falls to the bottom of the filter box 10. Impurities in the wastewater are intercepted on the upper part of the filter plate 20, thereby achieving wastewater filtration. During the above process, the first drive component 50 drives the scraper frame 60 to move back and forth along the upper part of the filter plate 20. When the scraper frame 60 moves back and forth, it scrapes the impurities retained on the upper part of the filter plate 20 to the edge of the filter plate 20, so that the impurities are removed from the filter holes 201, preventing the impurities from clogging the filter holes 201 and affecting the subsequent filtration effect of the wastewater. Because some impurities on the surface of the filter plate 20 are easily washed into the filter holes 201 by the wastewater when the wastewater passes through the filter holes, thus causing the filter holes 201 to become clogged. To prevent blockage, while the scraper frame 60 moves back and forth along the upper part of the filter plate 20, the second drive assembly belt 50 drives the cleaning assembly 40 to rotate left and right. When the cleaning assembly 40 rotates to the left, it cleans the filter holes 201 on the left side of the filter plate 20, causing the debris blocked in the left filter holes 201 to move to the upper part of the filter plate 20. With the leftward movement of the scraper frame 60, the debris, along with the debris remaining on the upper part of the filter plate 20, is scraped to the left edge of the filter plate 20. Similarly, when the cleaning assembly 40 rotates to the right, it cleans the filter holes 201 on the right side of the filter plate 20, causing the debris blocked in the right filter holes 201 to move to the upper part of the filter plate 20. With the rightward movement of the scraper frame 60, the debris, along with the debris remaining on the upper part of the filter plate 20, is scraped to the right edge of the filter plate 20.

[0034] Please see Figure 1In one embodiment, the first drive assembly 30 includes a motor 301, a lead screw 302, a second guide rod 303, a first slider 304, and a second slider 305. The first slider 304 and the second slider 305 are both fixedly installed on the upper part of the scraper frame 60. The motor 301 is fixedly installed on the side wall of the filter box 10. One end of the lead screw 302 is connected to the output end of the motor 301, and the other end passes through the second slider 305 and is threadedly engaged with the second slider 305. The second guide rod 303 is fixedly installed on the inner wall of the filter box 10, and the second guide rod 303 passes through the first slider 304 and is movably engaged with the first slider 304.

[0035] As wastewater passes through the filter holes 201, the motor 301 drives the lead screw 302 to rotate alternately in both directions. When the lead screw 302 rotates in the forward direction, it engages with the second slider 305 via a threaded connection, causing the second slider 305 to move to the right along the lead screw 302. As the second slider 305 moves to the right, it causes the scraper frame 60 to move to the right along the upper part of the filter plate 20, scraping away debris trapped on the upper part of the filter plate 20 to the upper right edge of the filter plate 20. When the lead screw 302 rotates in the reverse direction, it engages with the second slider 305 via a threaded connection, causing the second slider 305 to move to the right. The reverse thread engagement of block 305 drives the second slider 305 to move to the left along the screw 302. When the second slider 305 moves to the left, it drives the scraper frame 60 to move to the left along the upper part of the filter plate 20, so as to scrape the debris stuck on the upper part of the filter plate 20 to the upper left edge of the filter plate 20. When the screw 302 rotates in both directions, the first slider 304 slides adaptively along the second guide rod 303 to provide guidance for the movement of the scraper frame 60, so that the scraper frame 60 can smoothly scrape the debris.

[0036] Please see Figure 1 In one embodiment, the cleaning assembly 40 includes a support plate 401. One end of the support plate 401 is hinged to the middle of the bottom of the filter plate 20. A plurality of push rods 402 are fixedly arranged on both sides of the support plate 401. The plurality of push rods 402 located on one side of the support plate 401 correspond one-to-one with a plurality of filter holes 201 on the right side of the filter plate 20, and the plurality of push rods 402 located on the other side of the support plate 401 correspond one-to-one with a plurality of filter holes 201 on the left side of the filter plate 20.

[0037] When the scraper frame 60 moves to the right, the second drive assembly 50 drives the support plate 401 to rotate to the right relative to the filter plate 20 to a horizontal position. When the support plate 401 rotates to the right to a horizontal position, several push rods 402 on one side of it are inserted into several filter holes 201 on the right side of the filter plate 20, thereby pushing the debris in the filter holes 201 to the upper part of the filter plate 20, thus cleaning the filter holes 201 on the right side. As the scraper frame 60 moves to the right, the scraper frame 60 scrapes the debris that was originally stuck in the upper part of the filter holes 201 on the right side and the debris that was pushed to the upper part of the filter plate 20 through the inside of the filter holes 201 on the right side towards the upper right edge of the filter plate 20. As the scraper frame 60 moves to the left, the second drive assembly 50 drives the support plate 401 to rotate to the left relative to the filter plate 20 and become horizontal. When the support plate 401 rotates to the left and becomes horizontal, several push rods 402 on the other side are inserted into several filter holes 201 on the left side of the filter plate 20, thereby pushing the debris in the filter holes 201 to the upper part of the filter plate 20, thus cleaning the filter holes 201 on the left side. As the scraper frame 60 moves to the left, the scraper frame 60 scrapes the debris that was originally stuck in the upper part of the filter holes 201 on the left side and the debris that was pushed to the upper part of the filter plate 20 through the inside of the filter holes 201 on the left side towards the upper left edge of the filter plate 20.

[0038] Please see Figure 3 as well as Figure 4 In one embodiment, two sets of sliding grooves 103 are provided on the side wall of the filter box 10. One set of sliding grooves 103 is located above the filter plate 20, and the other set of sliding grooves 103 is located below the filter plate 20. The second drive assembly 50 includes a U-shaped connecting rod 501 and a pusher wheel 502. One end of the U-shaped connecting rod 501 extends from one set of sliding grooves 103 to the top of the filter plate 20 and is fixedly connected to the scraper frame 60. The other end extends from the other set of sliding grooves 103 to the bottom of the filter plate 20 and is rotatably connected to the pusher wheel 502.

[0039] When the scraper frame 60 moves to the right, the U-shaped connecting rod 501 drives the pusher wheel 502 to move synchronously to the right below the filter plate 20. When the pusher wheel 502 moves to the right, it acts on one side of the support plate 401, thereby driving the support plate 401 to rotate to the right and become horizontal. When the support plate 401 rotates to the right and becomes horizontal, several push rods 402 on one side of it are inserted into several filter holes 201 on the right side of the filter plate 20, thereby pushing the debris in the filter holes 201 on the right side to the upper part of the filter plate 20, thus cleaning the filter holes 201 on the right side. After several push rods 402 on one side of the support plate 401 are inserted into several filter holes 201 on the right side, the pusher wheel 502 rolls along the side wall of the support plate 401, and the support plate 401 remains horizontal. When the pusher wheel 502 rolls away from the side wall of the support plate 401, the support plate 401 rotates downward to a vertical state under the action of gravity. Then, as the scraper frame 60 moves to the left, the scraper frame 60 moves to the right and becomes horizontal with the help of the U-shaped connecting rod 501. The connecting rod 501 drives the pusher 502 to move synchronously to the left below the filter plate 20. When the pusher 502 moves to the left, it acts on the other side of the support plate 401, thereby driving the support plate 401 to rotate to the left and become horizontal. When the support plate 401 rotates to the left and becomes horizontal, several push rods 402 on the other side of it are inserted into several filter holes 201 on the left side of the filter plate 20, thereby pushing the debris in the filter holes 201 on the left side to the upper part of the filter plate 20, thus cleaning the filter holes 201 on the left side. After several push rods 402 on one side of the support plate 401 are inserted into several filter holes 201 on the left side, the pusher 502 rolls along the side wall of the support plate 401, and the support plate 401 remains horizontal. When the pusher 502 rolls away from the side wall of the support plate 401, the support plate 401 rotates downward to the vertical position under the action of gravity. Then, the scraper frame 60 again drives the pusher 502 to move to the right below the filter plate 20 with the help of the U-shaped connecting rod 501.

[0040] Please see Figure 4 , Figure 5 as well as Figure 6 In one embodiment, a first guide rod 202 is fixedly disposed at the middle position of the bottom of the filter plate 20, a limit end block 204 is fixedly disposed at the bottom of the first guide rod 202, a slide plate 203 is slidably disposed on the first guide rod 202, a pin shaft 205 is fixedly disposed at the bottom of the slide plate 203, a rotating plate 404 is fixedly disposed at the end of the support plate 401, the rotating plate 404 is rotatably engaged with the pin shaft 205, and push strips 403 are fixedly disposed on opposite sides of the support plate 401, the end of the push strips 403 is provided with an inclined surface 4031.

[0041] As the pusher wheel 502 moves to the right below the filter plate 20, it acts on the side wall of the support plate 401, thus pushing the side wall of the support plate 401 to rotate to the right and become horizontal. After the support plate 401 rotates to the right and becomes horizontal, as the pusher wheel 502 continues to move to the right, it acts on the inclined surface 4031 at one end of one set of pusher bars 403, thus pushing the support plate 401 to move vertically upward. When the support plate 401 moves vertically upward, it drives several push rods 402 on one side to insert vertically into the filter holes 201 on the right side from the bottom of the filter holes 201. This smoothly pushes the debris in the filter holes 201 on the right side to the upper part of the filter plate 20. Similarly, when the pusher wheel 502 moves to the left under the filter plate 20, the pusher wheel 502 acts on the other side wall of the support plate 401 in advance, thereby pushing the support plate 401 to rotate to the left and become horizontal. After the support plate 401 rotates to the left and becomes horizontal, as the pusher wheel 502 continues to move to the left, the pusher wheel 502 acts on the inclined surface 4031 at one end of another set of pusher strips 403, thereby pushing the support plate 401 to move vertically upward. When the support plate 401 moves vertically upward, it drives several push rods on one side. 402 is inserted vertically into the left side filter holes 201 from the bottom, thus smoothly pushing the debris in the left side filter holes 201 to the upper part of the filter plate 20. When the pusher wheel 502 acts on the side wall of the support plate 401 to push the support plate 401, the support plate 401 drives the rotating plate 404 to rotate relative to the pin 205. When the support plate 401 rotates horizontally, the rotating plate 404 acts horizontally on the bottom wall of the skateboard 203. At this time, the rotating plate 404 cannot rotate further, and the pusher wheel 502 can push the shoe upper 4031, thus smoothly driving the support plate 403. 01. When the support plate 401 moves vertically upward, it drives the slide plate 203 to slide along the first guide rod 202 through the rotating plate 404 and the pin 205. When the push wheel 502 rolls from the inclined surface 4031 to the surface of the push bar 403, the push wheel 502 rolls further along the surface of the push bar 403. At this time, the support plate 401 maintains the current horizontal height. Several push rods 402 are inserted into several filter holes 201, and the end of several push rods 402 away from the support plate 401 is flush with the upper surface of the filter plate 20, so that the scraper frame 60 can smoothly scrape the debris to the upper edge of the filter plate 20.

[0042] Please see Figure 1 In one embodiment, a drain outlet 101 is provided on the lower part of the side wall of the filter box 10, and a cleaning port is provided on the side wall of the filter box 10 at the upper part of the filter plate 20. A sealing door 102 is movably disposed in the cleaning port.

[0043] When the filter plate 20 is filtering wastewater, the sealing door 102 is closed to the cleaning port. At the same time, the wastewater passing through the filter hole 201 falls to the bottom of the filter box 10 and is discharged through the drain port 101. After the wastewater is filtered, the staff can open the sealing door 102 to clean the debris scraped to the upper edge of the filter plate 20 through the cleaning port.

[0044] In this embodiment of the invention, when high-salt industrial wastewater needs to be filtered, the wastewater can be introduced into the area above the filter plate 20. After entering the area above the filter plate 20, the wastewater passes through several filter holes 201 and falls to the bottom of the inner side of the filter box 10. Impurities in the wastewater are intercepted on the upper part of the filter plate 20, thereby achieving wastewater filtration. During the above process, the first driving component 50 drives the scraper frame 60 to move back and forth along the upper part of the filter plate 20. When the scraper frame 60 moves back and forth, it will be retained on the filter plate 20. The debris at the top is scraped to the edge of the filter plate 20, removing it from above the filter holes 201 and preventing it from clogging the holes and affecting the filtration effect of subsequent wastewater. Since some debris on the surface of the filter plate 20 can easily enter the filter holes 201 along with the wastewater as it passes through the filter holes, causing further clogging, to avoid this, while the scraper frame 60 moves back and forth along the upper part of the filter plate 20, the second drive assembly belt 50 drives the hole cleaning assembly 40. The cleaning assembly 40 rotates left and right. When it rotates to the left, it cleans the filter holes 201 on the left side of the filter plate 20, causing the debris clogging the left filter holes 201 to move to the upper part of the filter plate 20. Combined with the leftward movement of the scraper frame 60, this scrapes smaller debris, along with debris remaining on the upper part of the filter plate 20, to the left edge of the filter plate 20. Similarly, when the cleaning assembly 40 rotates to the right, it cleans the filter holes 201 on the right side of the filter plate 20, causing the debris clogging the right filter holes 201 to move to the upper part of the filter plate 20. Moving to the upper part of the filter plate 20, in conjunction with the rightward movement of the scraper frame 60, the debris, along with the debris retained on the upper part of the filter plate 20, is scraped to the right edge of the filter plate 20. Compared with the existing technology, when filtering high-salt industrial wastewater, it can not only automatically clean the debris directly retained on the upper part of the filter plate 20, but also automatically clean the debris blocked inside the filter holes 201, thereby improving the cleaning effect of debris, improving the anti-clogging effect of the filter holes 201, and effectively ensuring the filtration efficiency of wastewater.

[0045] The preferred embodiments of the present invention have been described in detail above. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
