Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, specifically to a separation and filtration device for the utilization process of sludge in water treatment. Background Technology

[0002] Sludge separation and filtration in water treatment is an important step in the wastewater treatment process. Its purpose is to separate the solids and liquids in the wastewater to facilitate subsequent treatment and disposal.

[0003] Chinese Patent Publication No. CN219558940U discloses a separation and filtration device for the utilization of sludge in water treatment. The device includes a separation filter box, filter components, and a scraping mechanism. The separation filter box contains multiple equally spaced filter components, each with a scraping mechanism in front, spanning two support frames. Each filter component includes a frame, a filter plate rotatably mounted within the central hole of the frame, and a drive mechanism for rotating the filter plate. The scraping mechanism includes a rubber scraper and a U-shaped frame. The rubber scraper is fixed to the bottom horizontal plate of the U-shaped frame and abuts against the filter plate. This invention, by configuring the frame, filter plate, and drive mechanism, allows the filter plate to rotate during use, ensuring that all parts of the filter plate are utilized. The scraping mechanism prevents filter plate clogging, solving the problem of asynchronous use and easy clogging of existing filter plates.

[0051] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0052] Example 1:

[0053] like Figures 1 to 6 As shown, this utility model provides a separation and filtration device for the utilization process of sludge in water treatment, including: a sewage filtration tank 1 and a filtration structure arranged in the sewage filtration tank 1 for filtering sludge particles in sewage.

[0054] The filtration structure includes an installation frame 2 arranged inside the wastewater filtration tank 1, a cleaning box 201 arranged above the installation frame 2, two drive rollers 202 rotatably installed on both sides of the cleaning box 201, two drive rollers 203 rotatably installed inside the installation frame 2, a filter screen 204 movably installed inside the installation frame 2 and the cleaning box 201, and the filter screen 204 is driven by the drive rollers 202 and 203. A reduction motor 205 is arranged on one side of the cleaning box 201, and the output end of the reduction motor 205 is arranged on the corresponding drive roller 202. The filter screen 204 can filter the wastewater passing through the wastewater filtration tank 1. By turning on the reduction motor 205, the drive rollers 202 can be rotated, which in turn drives the filter screen 204 to rotate in a circular motion, so that the surface of the filter screen 204 with attached impurities slowly moves into the cleaning box 201, while the surface without attached impurities moves into the wastewater filtration tank 1 for use.

[0055] Example 2:

[0056] Based on Example 1, in order to facilitate the cleaning of impurities attached to the filter screen 204, a cleaning structure for cleaning impurities is arranged on the filter structure.

[0057] The cleaning structure consists of two sets, each including a mounting carriage 3 slidably installed inside the cleaning box 201, a guide rod 301 slidably installed inside the mounting carriage 3, a mounting plate 302 located at one end of the guide rod 301, a cleaning brush 303 located on one side of the mounting plate 302 and in contact with the filter screen 204, a multi-stage electric push rod 304 located on one side of the cleaning box 201, with the telescopic end of the multi-stage electric push rod 304 located on one side of the mounting carriage 3, and a limiting component located on the mounting plate 302. When the multi-stage electric push rods 304 on both sides are opened, their telescopic ends reciprocate and drive the mounting carriage 3 to move. The mounting carriage 3 drives the guide rod 301 and the mounting plate 302, causing the cleaning brush 303 to clean the surface of the filter screen 204 and remove attached sludge and impurities.

[0058] Specifically, the limiting component includes a stop bar 305 arranged at one end of the guide rod 301 and a spring 306 arranged between the mounting plate 302 and the mounting slide 3. The spring 306 is slidably sleeved on the guide rod 301. The stop bar 305 can prevent the guide rod 301 from coming loose from the mounting slide 3. Under the elastic force of the spring 306, the adhesion between the cleaning brush 303 and the filter screen 204 can be improved.

[0059] The cleaning structure also includes two fixed rods 307 arranged on the inner wall of the cleaning box 201. The mounting slide 3 is slidably fitted on the two fixed rods 307. When the mounting slide 3 moves, it will slide on the fixed rods 307. The setting of the fixed rods 307 can restrict the sliding of the mounting slide 3 in the horizontal direction.

[0060] Example 3:

[0061] Based on Example 1, a sealing structure is arranged on the filter structure in order to improve the sealing between the filter screen 204 and the mounting frame 2.

[0062] The sealing structure consists of two sets. Each set includes a sealing frame 4 rotatably mounted on one side of the mounting frame 2, an auxiliary electric push rod 401 arranged above the mounting frame 2, and a connecting rod 402 rotatably mounted on the telescopic end of the auxiliary electric push rod 401. One end of the connecting rod 402 is rotatably mounted on the sealing frame 4. When the auxiliary electric push rod 401 is turned on, its telescopic end will push the connecting rod 402 to move. The connecting rod 402 can drive the sealing frame 4 to flip, so that the sealing frame 4 is no longer in contact with the filter screen 204. At this time, the restriction on the filter screen 204 can be released. Conversely, the sealing frame 4 flips in the opposite direction and can fit onto the filter screen 204, thus restricting the position of the filter screen 204.

[0063] The sealing structure also includes a compression assembly arranged on the sealing frame 4 for adhering to the filter screen 204.

[0064] Specifically, the extrusion assembly includes a sealing groove 403 inside the mounting frame 2 and a rubber ring 404 arranged on one side of the sealing frame 4 and in contact with the filter screen 204. The rubber ring 404 is located inside the sealing groove 403. When the sealing frame 4 is flipped, the rubber ring 404 can be pressed onto the filter screen 204, and a part of the filter screen 204 is pressed into the sealing groove 403, which can improve the sealing effect at the connection between the filter screen 204 and the mounting frame 2.

[0065] Working Principle: The filter screen 204 filters the sewage passing through the sewage filtration tank 1, blocking sludge particles and impurities. When cleaning the filter screen 204 is required, sewage delivery to the sewage filtration tank 1 is stopped, and the auxiliary electric push rods 401 on both sides are activated. The telescopic ends of the auxiliary electric push rods 401 push the connecting rod 402 to move. The connecting rod 402 causes the sealing frame 4 to flip, disengaging the rubber ring 404 from the filter screen 204. This releases the restriction on the filter screen 204. Subsequently, the reduction motor 205 is activated to drive the transmission roller 202 to rotate. The rotation of the transmission roller 202 causes the filter screen 204 to move in a circular motion. The two transmission rollers 203 and the two transmission rollers 202 are arranged to cooperate with the filter screen 204, thus enabling the filter screen 204 to move when the transmission roller 202 rotates. The filter screen 204, along with the surface covered with impurities, slowly moves into the cleaning box 201. Simultaneously, the multi-stage electric push rods 304 on both sides can be activated, causing their telescopic ends to reciprocate and move the mounting slide 3 accordingly. The mounting slide 3 slides on the fixed rod 307 and moves the guide rod 301, causing the guide rod 301 to move the mounting plate 302 and the cleaning brush 303. The moving cleaning brush 303 cleans the surface of the filter screen 204, removing the attached sludge and impurities. The sludge and impurities fall into the cleaning box 201 and slide out along the inclined surface of the bottom inner wall of the cleaning box 201, preventing the cleaned impurities from remaining in the sewage filtration tank 1. After cleaning, the telescopic end of the auxiliary electric push rod 401 can be reset, which in turn pulls the sealing frame 4 to flip and reset. The reset sealing frame 4 causes the rubber ring 404 to press onto the filter screen 204, improving the sealing effect at the connection between the filter screen 204 and the mounting frame 2.

[0066] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
