Description

Technical Field

[0001] This utility model relates to the field of fiber disc filter backwashing technology, specifically a fiber disc filter backwashing device. Background Technology

[0002] Fiber disc filters, as a high-efficiency device that relies on precision filter cloth to achieve solid-liquid separation, achieve deep wastewater purification through a synergistic mechanism of physical interception and backwashing. The device mainly consists of four core components: the filter disc system, the backwashing mechanism, the sludge removal mechanism, and the drive and control system. Among these, the backwashing mechanism is the core component ensuring its efficient and stable operation. It periodically removes various pollutants trapped by the filter cloth, providing a solid guarantee for the continuous and stable filtration performance of the equipment.

[0003] Existing fiber disc filter backwashing devices typically employ a design where the backwashing suction cups are tightly fitted to the filter cloth to ensure sufficient negative pressure and effective suction of sludge trapped on the filter cloth surface. However, after prolonged continuous operation, this design leads to varying degrees of wear between the backwashing suction cups and the filter cloth due to continuous friction. This wear not only necessitates frequent shutdowns for replacement and maintenance, consuming significant time and manpower, but also significantly shortens the lifespan of both the backwashing suction cups and the filter cloth, thereby substantially increasing overall operating costs. To effectively reduce friction between the backwashing suction cups and the filter cloth and extend their service life, this application proposes a fiber disc filter backwashing device. Utility Model Content

[0004] The purpose of this utility model is to provide a backwashing device for a fiber disc filter, in order to solve the problem that the friction between the backwashing suction cup and the filter cloth in the existing fiber disc filter backwashing device is too large, and different wear will occur after long-term operation. This not only requires a lot of time to replace and maintain the device, but also shortens the service life of the backwashing suction cup and the filter cloth, increasing the cost of use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a fiber disc filter backwashing device, including an installation arm, a hydraulic cover component at the bottom of the installation arm, two rubber sealing roller components symmetrically arranged on both sides inside the hydraulic cover component, a backwashing spray pipe component and a sludge suction component respectively arranged on one side close to each other, and two spring clamping components symmetrically arranged at both ends of the rubber sealing roller component passing through the hydraulic cover component; The hydraulic cover component includes a negative pressure cover. Two hydraulic cylinders are symmetrically arranged at both ends of the top of the negative pressure cover. A partition is fixedly connected to one side of the inside of the negative pressure cover. Waist-shaped grooves are symmetrically arranged on both sides of the two ends of the negative pressure cover. The partition divides the inside of the negative pressure cover into a backwashing zone and a sludge suction zone, and the backwashing zone is larger than the sludge suction zone.

[0006] The tops of the two hydraulic cylinders are fixedly connected to both ends of the mounting arm.

[0007] The spring clamping component includes a guide rod mounting block, a guide rod is slidably connected to the inner side of the guide rod mounting block, the guide rod mounting block is fixedly connected to the outer side of the negative pressure cover, a roller mounting block is fixedly connected to the other end of the guide rod, and a clamping spring is provided on the outer side of the guide rod. One end of the clamping spring is fixedly connected to the guide rod mounting block, and the other end of the clamping spring is fixedly connected to the roller mounting block.

[0008] The rubber sealing roller component includes a roller body, a sealing rubber layer fixedly connected to the outside of the roller body, two ends of the roller body passing through two waist-shaped grooves and fixedly connected to two roller mounting blocks respectively, and two ends of the roller body slidingly connected to the negative pressure cover through the waist-shaped grooves.

[0009] The backwash nozzle component includes a water supply pipe, which passes through the negative pressure hood and is fixedly connected to the nozzle. The outside of the water supply pipe is fixedly connected to the negative pressure hood. The nozzle end of the nozzle is inclined towards the bottom of the partition, and the nozzle is located inside the backwash zone.

[0010] The sludge suction component includes a sludge discharge pipe, which passes through a negative pressure hood and is fixedly connected to a sludge suction hood. The outer side of the sludge discharge pipe is fixedly connected to the negative pressure hood, and the sludge suction hood is located inside the sludge suction area.

[0011] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model uses two hydraulic cylinders to drive the negative pressure cover close to the filter cloth surface, so that the two rubber sealing roller components are in contact with the filter cloth. As the filter cloth rotates, the sealing rubber layer on the outside of the two rollers rolls along the filter cloth. This changes the original sliding friction between the backwash suction cup and the filter cloth to rolling friction between the sealing rubber layer and the filter cloth, avoiding direct contact between the sludge suction component and the filter cloth, reducing friction, thereby reducing wear on the filter cloth and the sludge suction component, extending service life, avoiding frequent downtime for maintenance, and reducing operating costs.

[0012] 2. This utility model uses a compression spring to push the roller mounting block down along the guide rod, thereby driving the rubber sealing roller component to better press the filter cloth, reducing the gap between the negative pressure hood and the filter cloth, ensuring sufficient negative pressure inside the negative pressure hood, and facilitating effective suction of sludge from the surface of the filter cloth.

Detailed Implementation

[0014] 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.

[0015] Please see Figure 1-4 This utility model provides a technical solution: a fiber disc filter backwashing device, including an installation arm 1, a hydraulic cover component 2 at the bottom of the installation arm 1, two rubber sealing roller components 3 symmetrically arranged on both sides inside the hydraulic cover component 2, a backwashing nozzle component 4 and a sludge suction component 5 respectively arranged on one side close to each other, and two spring clamping components 6 symmetrically arranged through the hydraulic cover component 2 at both ends of the rubber sealing roller component 3. The hydraulic cover component 2 includes a negative pressure cover 201. Two hydraulic cylinders 202 are symmetrically arranged at both ends of the top of the negative pressure cover 201. A partition 203 is fixedly connected to one side of the inside of the negative pressure cover 201. Waist-shaped grooves 204 are symmetrically arranged on both sides of the negative pressure cover 201. The partition 203 divides the inside of the negative pressure cover 201 into a backwashing zone 205 and a sludge suction zone 206. The backwashing zone 205 is larger than the sludge suction zone 206. By setting the partition 203, the gap between the sludge suction zone 206 and the outside can be reduced, thereby ensuring the negative pressure inside the sludge suction zone 206 and improving the suction effect.

[0016] The tops of the two hydraulic cylinders 202 are fixedly connected to both ends of the mounting arm 1. By setting up two hydraulic cylinders 202, it is easy to push the negative pressure cover 201 close to the filter cloth for backwashing.

[0017] The spring-pressing component 6 includes a guide rod mounting block 601, a guide rod 602 slidably connected to the inner side of the guide rod mounting block 601, a guide rod mounting block 601 fixedly connected to the outer side of the negative pressure cover 201, a roller mounting block 603 fixedly connected to the other end of the guide rod 602, and a pressing spring 604 provided on the outer side of the guide rod 602. One end of the pressing spring 604 is fixedly connected to the guide rod mounting block 601, and the other end of the pressing spring 604 is fixedly connected to the roller mounting block 603. By setting the spring-pressing component 6, the pressing force of the rubber sealing roller component 3 on the filter cloth can be avoided to be too tight or too loose, so that the rubber sealing roller component 3 can better fit the filter cloth and ensure the negative pressure inside the negative pressure cover 301.

[0018] The rubber sealing roller component 3 includes a roller body 301, a sealing rubber layer 302 fixedly connected to the outside of the roller body 301, and two ends of the roller body 301 passing through two waist-shaped grooves 204 and fixedly connected to two roller mounting blocks 603 respectively. The two ends of the roller body 301 are slidably connected to the negative pressure cover 201 through the waist-shaped grooves 204. By setting the sealing rubber layer 302, the filter cloth can be better fitted, the gaps can be reduced, and the negative pressure inside the negative pressure cover 201 can be guaranteed.

[0019] The backwash nozzle component 4 includes a water supply pipe 401, which passes through the negative pressure cover 201 and is fixedly connected to a nozzle 402. The outside of the water supply pipe 401 is fixedly connected to the negative pressure cover 201. The nozzle end of the nozzle 402 is inclined toward the bottom of the partition 203 and the nozzle 402 is located inside the backwash zone 205. By setting the inclined nozzle 402, it is easier to better rinse the sludge on the filter cloth.

[0020] The sludge suction component 5 includes a sludge discharge pipe 501, which passes through the negative pressure cover 201 and is fixedly connected to the sludge suction cover 502. The outside of the sludge discharge pipe 501 is fixedly connected to the negative pressure cover 201, and the sludge suction cover 502 is located inside the sludge suction area 206.

[0021] Working principle: The mounting arm 1 is fixed to the inside of the filter tank. Two hydraulic cylinders 202 drive the negative pressure cover 201 to approach the rotating filter cloth, thereby causing the two rubber sealing roller components 3 to press against the filter cloth. The sealing rubber layer 302 on the roller body 301 contacts the filter cloth and receives a reaction force, which in turn drives the two roller mounting seats at both ends of the roller body 301 to move along the guide rod 602, causing the compression spring 604 to be compressed. The filter cloth rotates, which drives the rubber sealing roller components 3 to rotate. Through the external water pump, high-pressure water is sent into the spray pipe 402 through the water supply pipe 401 to wash the sludge on the surface of the filter cloth. The sludge in the backwashing zone 205 enters the sludge suction zone 206 through the bottom of the partition 203. The external suction pump sucks out the sludge in the sludge suction zone 206 through the sludge discharge pipe 501 and the sludge suction cover 502.
