Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment technology, and in particular to a filter cloth cleaning mechanism for filter beds. Background Technology

[0002] A cloth filter is a filtration device used in water treatment, primarily to remove suspended solids, particulate matter, algae, and other impurities from water to improve water quality. It is widely used in wastewater treatment, tap water treatment, industrial wastewater treatment, and rainwater treatment.

[0003] Existing filter cloth cleaning devices are prone to wear and damage during prolonged scraping operations, especially under high-frequency, high-intensity working conditions. Components of the cleaning device (such as scrapers, brushes, or drive mechanisms) may fail due to friction, corrosion, or fatigue. This not only affects the cleaning effect but may also lead to secondary contamination or damage to the filter cloth. Therefore, regular inspection, maintenance, and replacement of the cleaning device are crucial. However, existing cleaning devices are typically bolted inside the water tank. While this installation method is secure, it presents numerous inconveniences during disassembly and replacement. For example, operators need to enter the water tank or use specialized tools for disassembly, which is time-consuming and labor-intensive. Working in a high-humidity, enclosed environment increases maintenance difficulty and safety hazards. Furthermore, frequent disassembly and installation may cause additional mechanical damage to the water tank structure or the cleaning device itself, further affecting the equipment's lifespan and operating efficiency.

[0004] The purpose of this invention is to provide a filter cloth cleaning mechanism for filter beds, which can solve the problems mentioned in the background.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a filter cloth cleaning mechanism for a filter bed, comprising: a water tank, two base plates and a filter disc, two bases fixedly installed on one side of the outer surface of the water tank, rotating plates rotatably installed inside the two bases, three arc-shaped grooves opened inside the two rotating plates, sliders slidably arranged inside the six arc-shaped grooves, support plates fixedly installed on the upper side of the two bases, three sliding grooves opened inside the two support plates, clamping blocks fixedly installed on the upper side of the six sliders, and the six clamping blocks slidably arranged inside the six sliding grooves respectively.

[0006] In a preferred embodiment, a second groove is provided on one side of the outer surface of each of the two bases, and a handle is fixedly installed on one side of the outer surface of each of the two rotating plates. The two handles are slidably disposed inside the two second grooves respectively.

[0007] The technical effect of adopting the above-mentioned further solution is that by setting the second slide groove, it is easier for the staff to manually operate the rotating plate, thereby improving the disassembly efficiency of the base plate.

[0008] In a preferred embodiment, an extension plate is fixedly installed on one side of the outer surface of each of the two base plates, and a scraper is slidably sleeved on the outer surface of each of the two extension plates.

[0009] The technical effect of adopting the above-mentioned further solution is that by attaching the scraper to the filter cloth, the dirt on the surface of the filter cloth can be scraped off.

[0010] In a preferred embodiment, a spring is fixedly installed inside each of the two scrapers, and the other end of each spring is connected to one end of the two extension plates.

[0011] The technical effect of adopting the above-mentioned further solution is that when the filter disc rotates, the spring inside the scraper will always push the scraper, so that one end of the scraper will always be in contact with the outer surface of the filter disc, thereby achieving all-round cleaning of the filter cloth.

[0012] In a preferred embodiment, a fixing frame is fixedly installed on one side of the outer surface of each of the two scrapers, a sliding frame is slidably arranged inside each of the two fixing frames, and a storage bag is fixedly installed at the bottom of each of the two sliding frames.

[0013] The technical effect of adopting the above-mentioned further solution is that the dirt scraped off the filter cloth will fall along the scraper into the inside of the collection bag, which facilitates the unified collection and treatment of dirt.

[0014] In a preferred embodiment, each of the two fixed frames has a sliding groove three inside, and each of the two sliding frames has a limiting member slidably arranged inside one side. The other end of each of the two limiting members is connected to a spring two, and the other end of each of the two spring two is fixedly connected inside the two sliding frames. Each of the two sliding grooves three has a sliding rod slidably arranged inside.

[0015] The technical effect of adopting the above-mentioned further solution is that by manually pressing the slide bar on one side of the fixed frame, the slide bar slides inside the slide groove three, thereby pushing the limiting member to compress the spring two into the slide frame, so that the slide frame can be removed for replacement or cleaning.

[0016] In a preferred embodiment, support frames are fixedly installed on both sides of the outer surface of the filter disc, and both support frames are fixedly installed inside the water tank.

[0017] The technical advantage of adopting the above-mentioned further solution is that the rotation of the filter disc can be facilitated by rotating the filter disc between the two support frames.

[0018] In a preferred embodiment, a driven plate is fixedly installed at one end of the outer surface of the filter disc, a motor is fixedly installed on the upper side of the water tank, a synchronous belt is sleeved on the outer surface of the output end of the motor, and the other end of the synchronous belt is sleeved on the outer surface of the driven plate.

[0019] The technical effect of adopting the above-mentioned further solution is that the motor can control the filter disc to continue rotating through the synchronous belt drive.

[0020] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0021] 1. In use, the base plate can be disassembled by rotating the rotating plate, which is a more convenient and efficient installation and disassembly solution, greatly reducing maintenance time, reducing operation difficulty, and improving the overall reliability and service life of the equipment.

[0022] 2. In use, since the filter disc is usually polygonal, the traditional scraping device has a fixed length, which will result in dead corners and the scraping device cannot achieve cleaning. Therefore, a spring is set at one end of the extension plate, and a scraper is fitted on the outer surface of the extension plate. When the filter disc rotates, the spring inside the scraper will always push the scraper, so that one end of the scraper will always be in contact with the outer surface of the filter disc, thereby achieving all-round cleaning of the filter cloth.

[0031] 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.

[0032] Please see Figure 1 - Figure 6 This utility model provides a technical solution: a filter cloth cleaning mechanism for a filter bed, comprising: a water tank 101, two base plates 201 and a filter disc 301. Two bases 102 are fixedly installed on one side of the outer surface of the water tank 101. Rotating plates 106 are rotatably installed inside the two bases 102. Three arc-shaped grooves 107 are opened inside the two rotating plates 106. Sliding sliders 108 are slidably arranged inside the six arc-shaped grooves 107. Support plates 103 are fixedly installed on the upper side of the two bases 102. Three sliding grooves 104 are opened inside the two support plates 103. Clamping blocks 109 are fixedly installed on the upper side of the six sliding blocks 108. The six clamping blocks 109 are slidably arranged inside the six sliding grooves 104 respectively.

[0033] like Figure 1 - Figure 6 As shown, a second groove 105 is provided on one side of the outer surface of each of the two bases 102, and a handle 110 is fixedly installed on one side of the outer surface of each of the two rotating plates 106. The two handles 110 are slidably disposed inside the two second grooves 105. By setting the second grooves 105, it is convenient for the staff to manually operate the rotating plates 106, thereby improving the disassembly efficiency of the base plate 201.

[0034] like Figure 1 - Figure 6 As shown, an extension plate 202 is fixedly installed on one side of the outer surface of each of the two base plates 201. A scraper 203 is slidably sleeved on the outer surface of each of the two extension plates 202. By attaching the scraper 203 to the filter cloth, the dirt on the surface of the filter cloth can be scraped off.

[0035] like Figure 1 - Figure 6 As shown, springs 204 are fixedly installed inside both scrapers 203. The other ends of the two springs 204 are respectively connected to one end of the two extension plates 202. When the filter disc 301 rotates, the springs 204 inside the scraper 203 will always push the scraper 203, so that one end of the scraper 203 is always in contact with the outer surface of the filter disc 301, thereby achieving all-round cleaning of the filter cloth.

[0036] like Figure 1 - Figure 6 As shown, a fixed frame 210 is fixedly installed on one side of the outer surface of each of the two scrapers 203. A sliding frame 205 is slidably installed inside each of the two fixed frames 210. A collection bag 206 is fixedly installed at the bottom of each of the two sliding frames 205. The dirt scraped off the filter cloth will fall along the scraper 203 into the collection bag 206, which facilitates the collection and treatment of dirt.

[0037] like Figure 1 - Figure 6 As shown, each of the two fixed frames 210 has a sliding groove 207 inside. Each of the two sliding frames 205 has a limiting member 208 slidably installed inside one side. The other end of each limiting member 208 is connected to a spring 209. The other ends of each spring 209 are fixedly connected inside the two sliding frames 205. Each of the two sliding grooves 207 has a sliding rod 211 slidably installed inside. By manually pressing the sliding rod 211 on one side of the fixed frame 210, the sliding rod 211 slides inside the sliding groove 207, thereby pushing the limiting member 208 to compress the spring 209 and enter the sliding frame 205. Thus, the sliding frame 205 can be removed for replacement or cleaning.

[0038] like Figure 1 - Figure 6 As shown, support frames 303 are fixedly installed on both sides of the outer surface of the filter disc 301. Both support frames 303 are fixedly installed inside the water tank 101. The filter disc 301 can be rotated between the two support frames 303 to facilitate its rotation.

[0039] like Figure 1 - Figure 6 As shown, a driven plate 304 is fixedly installed at one end of the outer surface of the filter disc 301, and a motor 302 is fixedly installed on the upper side of the water tank 101. A synchronous belt 305 is sleeved on the outer surface of the output end of the motor 302, and the other end of the synchronous belt 305 is sleeved on the outer surface of the driven plate 304. Through the transmission of the synchronous belt 305, the motor 302 can control the filter disc 301 to continue to rotate.

[0040] Working principle: When cleaning the filter cloth, the motor 302 is started first. The motor 302 drives the driven plate 304 to rotate synchronously through the synchronous belt 305. In turn, the driven plate 304 drives the filter disc 301 to rotate between the two support frames 303. As the filter disc 301 rotates counterclockwise, it drives the filter cloth on the outer surface to rotate synchronously. Since the scraper 203 is in close contact with the filter cloth, the dirt on the outer surface is scraped off by the scraper 203 and carried along the filter cloth as it rotates. Spring 204 falls onto the outer surface of the storage bag 206. Since the filter disc 301 is typically polygonal, traditional scraping devices with a fixed length will have dead angles, making cleaning impossible. Therefore, spring 204 is installed at one end of the extension plate 202, and a scraper 203 is fitted onto the outer surface of the extension plate 202. When the filter disc 301 rotates, the spring 204 inside the scraper 203 will continuously push the scraper 203, ensuring that one end of the scraper 203 remains in contact with the filter disc 301. The outer surface is adhered, thus achieving all-round cleaning of the filter cloth. When the inside of the storage bag 206 is full of dirt, the slide bar 211 on one side of the fixed frame 210 is manually pressed. The slide bar 211 slides inside the slide groove 207, thereby pushing the limiting member 208 to compress the spring 209 into the sliding frame 205, so that the sliding frame 205 can be removed for replacement or cleaning. When the scraper 203 needs maintenance, the handle 110 on one side of the base 102 is manually turned. The rotating plate 106 rotates inside the base 102. Since the three arc-shaped grooves 107 on the surface of the rotating plate 106 are all designed to gradually move towards the center, and the clamping block 109 on the upper side of the slider 108 is slidably disposed inside the slide groove 104, rotating the rotating plate 106 in the opposite direction will cause the slider 108 inside the arc-shaped groove 107 to drive the clamping block 109 to move away from the center, thereby releasing the clamping block 109 from the base plate 201, thus making it easier to remove the base plate 201 for replacement.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
