Description

Technical Field

[0001] This application relates to the technical field of wastewater treatment, and in particular to a wastewater treatment device for water supply and drainage that facilitates sludge removal. Background Technology

[0002] Industrial wastewater often contains sludge, which can easily cause blockages during transportation. Therefore, it is necessary to remove the sludge and store the wastewater and sludge separately for treatment.

[0003] Currently, various methods are commonly used in wastewater treatment for water supply and drainage to separate sludge from wastewater and to discharge sludge. One common method is sedimentation, where wastewater is allowed to settle in a sedimentation tank for a period of time, allowing the sludge to naturally settle to the bottom. The sludge is then discharged through a sludge discharge pipe at the bottom. However, this method requires a long sedimentation time and a large area. To address this, existing technologies employ another method: using filtration equipment such as filter screens or filter cloths. Wastewater passes through these filter media, where the sludge is trapped, achieving solid-liquid separation. However, this method is prone to clogging by sludge, requiring frequent replacement or cleaning of the filter media, increasing maintenance costs and workload. Therefore, further improvements are needed. Utility Model Content

[0004] To address the above problems, this application provides a wastewater treatment device for water supply and drainage that facilitates sludge removal.

[0005] This application provides a wastewater treatment device for water supply and drainage that facilitates sludge removal, employing the following technical solution:

[0006] A wastewater treatment device for water supply and drainage with easy sludge removal includes a tank body. A partition is installed inside the tank body to divide it into a wastewater tank and a sludge tank. The tank body is equipped with a conveying component to transport a mixture of wastewater and sludge to the wastewater tank. The wastewater tank is equipped with a separation component for separating sludge and wastewater. The separation component includes a filter cylinder, a spiral steel beam built into the filter cylinder, and a first driving component to rotate the filter cylinder. The spiral steel beam and the filter cylinder rotate coaxially. The filter cylinder is connected to the conveying component. The output end of the filter cylinder is equipped with an input component to transport dewatered sludge to the sludge tank. A cleaning component is installed on the wastewater tank for cleaning the filter cylinder.

[0007] By adopting the above technical solution, after the conveying component transports the sewage and sludge mixture into the filter cartridge, the filter cartridge rotates under the drive of the first driving component. In conjunction with the coaxially rotating spiral steel beam, sewage and sludge can be separated efficiently. At the same time, the spiral steel beam can push the sludge to the output end of the filter cartridge. Through the input component, the dewatered sludge can be transported from the output end of the filter cartridge to the sludge tank, thus completing the sludge transfer.

[0008] During use, due to the influence of centrifugal force, a small amount of sludge may clog the filter holes of the filter cartridge, affecting the subsequent filtration effect. To address this, a cleaning component is provided to clean the filter cartridge, ensuring that the separation component works continuously and stably, thereby improving the sludge discharge efficiency and wastewater treatment effect of the entire wastewater treatment device.

[0009] Preferably, the filter cartridge is covered with a U-shaped cover.

[0010] By adopting the above technical solution, the U-shaped cover can cover the filter cartridge, which can reduce the splashing of sewage and sludge during the separation process and play a protective role.

[0011] Preferably, the first driving component includes a rack coaxially sleeved on the filter cartridge, a drive gear meshing with the rack, and a first drive motor that drives the drive gear to rotate. The first drive motor is disposed on the outer wall of the U-shaped cover, and the U-shaped cover has a rotating groove for the drive gear to pass through.

[0012] By adopting the above technical solution, the first drive motor drives the active gear to rotate. The rotation of the filter cartridge is achieved through the meshing of the active gear with the rack sleeved on the filter cartridge, thereby enabling the filter cartridge to separate sludge and sewage. The first drive motor is set on the outer wall of the U-shaped cover, and a rotating groove is opened in the U-shaped cover for the active gear to pass through, which facilitates the installation of the first drive motor and the realization of power transmission.

[0013] Preferably, the filter cartridges are provided in a plurality of manner, and the first driving component further includes pulleys fixedly connected to the filter cartridges and a conveyor belt wound around two adjacent pulleys.

[0014] By adopting the above technical solution, setting up several filter cartridges increases the sewage treatment capacity and improves the treatment efficiency; the pulleys and conveyor belts in the first drive component enable multiple filter cartridges to rotate synchronously, ensuring the consistency and stability of the operation of each filter cartridge, and further improving the working performance of the sewage treatment device.

[0015] Preferably, the cleaning assembly includes a scraper abutting against the outer peripheral wall of the filter cartridge, a connecting seat connected to the scraper, and a second driving member that drives the connecting seat to reciprocate along the length of the filter cartridge.

[0016] By adopting the above technical solution, the scraper abuts against the outer peripheral wall of the filter cartridge. When the connecting seat moves back and forth along the length of the filter cartridge, it can scrape and clean the outer peripheral wall of the filter cartridge, reducing the impact of sludge adhesion on the filtration effect.

[0017] Preferably, the second driving component includes a driven gear meshing with the rack, a lead screw coaxially connected to the driven gear, and a guide rod arranged parallel to the length direction of the lead screw. The guide rod slides through the connecting seat, and a rotating plate is provided inside the U-shaped cover for rotatably connecting the other end of the lead screw and the other end of the guide rod.

[0018] By adopting the above technical solution, the driven gear meshes with the rack, causing the driven gear to rotate and drive the lead screw to rotate. In conjunction with the guide rod, the connecting seat can move back and forth along the length of the filter cartridge, thereby realizing the automatic cleaning of the outer peripheral wall of the filter cartridge by the scraper, improving cleaning efficiency, ensuring the filtration performance of the filter cartridge, and enabling the sewage treatment device to operate continuously and effectively.

[0019] Preferably, the lead screw is a reciprocating lead screw.

[0020] By adopting the above technical solution, the lead screw is a reciprocating lead screw, which can drive the scraper to scrape the filter cartridge reciprocally during the unidirectional rotation of the filter cartridge, reducing the need to frequently change the driving direction of the drive motor.

[0021] Preferably, the cleaning assembly further includes a water spray pipe connected to the connecting seat, a water pipe connected to the water spray pipe, and a water pump connected to the water pipe, wherein the water pump is built into the sewage tank, and the water pipe is a corrugated flexible hose.

[0022] By adopting the above technical solution, a spray pipe, a water pipe, and a water pump are installed. The water pump can draw water from the sewage tank and deliver it to the spray pipe through the water pipe. The water pump works in conjunction with the scraper to clean the filter cartridge, thereby improving the cleaning effect. The water pipe is a corrugated flexible hose, which can adapt to the reciprocating movement of the connector and ensure normal water supply to the spray pipe during the cleaning process.

[0023] Preferably, the water spray pipe is arc-shaped and coaxial with the filter cartridge, and the surface of the water spray pipe near the filter cartridge has several water outlet holes.

[0024] By adopting the above technical solution, the water spray pipe is set to be arc-shaped and coaxial with the filter cartridge. With the addition of several water outlet holes set near the surface of the filter cartridge, water can be sprayed more evenly onto the surface of the filter cartridge, thereby improving the cleaning effect on the filter cartridge.

[0025] In summary, this utility model has the following beneficial effects:

[0026] 1. A separation assembly consisting of a filter cartridge, a spiral steel beam, and a first driving component is used to separate sewage and sludge mixtures, which solves the problems of poor separation effect of sedimentation method and easy clogging of filtration equipment, and can separate sludge and sewage more efficiently;

[0027] 2. By using the input component to transport the dewatered sludge to the sludge tank, the inconvenience of sludge discharge and the possibility of pipe blockage caused by traditional methods are reduced, making sludge discharge more convenient;

[0028] 3. The cleaning component can clean the filter cartridge, ensuring its normal operation, extending the service life of the equipment, and reducing maintenance costs and workload. Attached Figure Description

Detailed Implementation

[0038] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail below.

[0039] This application discloses a wastewater treatment device for water supply and drainage that facilitates sludge removal.

[0040] Example:

[0041] A wastewater treatment device for water supply and drainage that facilitates sludge removal, as described in the following reference. Figure 1The system includes a pool body 1, which is equipped with a partition 11 to divide the pool body 1 into a sewage pool 12 and a sludge pool 13. The pool body 1 is equipped with a conveying component 14 to transport the sewage and sludge mixture into the sewage pool 12. The sewage pool 12 is equipped with a separation component 2 for separating sludge and sewage. The separation component 2 is equipped with an input component 3 for transporting dewatered and dehydrated sludge into the sludge pool 13.

[0042] Specifically, the conveying component 14 can be an input pipe 31 connected to the separation component 2.

[0043] Reference Figure 2 , Figure 3 The separation component 2 specifically includes a filter cylinder 21, a spiral steel beam 22 built into the filter cylinder 21, and a first driving component 23 that drives the filter cylinder 21 to rotate. In this embodiment, the filter cylinder 21 has a cylindrical structure and can be made of a metal filter screen material with a certain filtration accuracy or a high-strength plastic filter screen, depending on the requirements. The length direction of the filter cylinder 21 is parallel to the length direction of the sewage tank 12, and several filter cylinders 21 are spaced apart along the width direction of the sewage tank 12, depending on the requirements. In this embodiment, three filter cylinders 21 are specifically shown. One end of the filter cylinder 21 is connected to the input pipe 31 to receive the sewage-sludge mixture. During operation, the filter cylinder 21 rotates under the drive of the first driving component 23.

[0044] Furthermore, to reduce the splashing of sewage and sludge during the separation process, a U-shaped cover 24 is provided on the filter cartridge 21.

[0045] The spiral steel beam 22 is built into the filter cylinder 21 and fixedly connected to the inner wall of the filter cylinder 21, so that it rotates coaxially with the filter cylinder 21. It is generally made of stainless steel and has good corrosion resistance and strength. The spiral structure of the spiral steel beam 22 can push the sludge to the output end when the filter cylinder 21 rotates, thus assisting in the discharge of sludge.

[0046] Reference Figure 3 , Figure 4 The first driving component 23 includes a rack 231 coaxially sleeved on the filter cartridge 21, a drive gear 232 meshing with the rack 231, and a first drive motor 233 driving the drive gear 232 to rotate. The rack 231 surrounds the outer peripheral wall of the filter cartridge 21 and is tightly fixedly connected to it. The drive gear 232 meshes with the rack 231. The first drive motor 233 is fixedly connected to the outer wall of the U-shaped cover 24, which has a rotation groove 241 through which the drive gear 232 passes. When the first drive motor 233 starts, the drive gear 232 rotates, driving the filter cartridge 21 to rotate via the rack 231. To reduce the number of first drive motors 233, in this embodiment, the number of motors can be reduced as follows: Figure 5As shown, a pulley 234 is coaxially arranged with the filter cylinder 21 and a conveyor belt 235 is wound around two adjacent pulleys 234. The pulley 234 is fixedly connected to the filter cylinder 21. The rotation of the filter cylinder 21 drives the rotation of several filter cylinders 21 through the conveyor belt 235.

[0047] Back Figure 2 The output end of the filter cartridge 21 is equipped with an input component 3 for conveying dewatered sludge to the sludge tank 13. The input component 3 is responsible for conveying the dewatered sludge to the sludge tank 13. In this embodiment, the input component 3 includes an input pipe 31 communicating with the filter cartridge 21, a sludge conveying bin 32 communicating with the input pipe 31, a screw propeller 33 built into the sludge conveying bin 32, a second drive motor 34 driving the screw propeller 33 to rotate, and an output pipe 35 communicating with the sludge conveying bin 32. A filter plate may be provided at the bottom of the sludge conveying bin 32 for secondary filtration. The second drive motor 34 is fixedly connected to the outer top wall of the sludge conveying bin 32, and the output shaft of the second drive motor 34 rotatably passes through the sludge conveying bin 32 to be fixedly connected with the screw propeller 33. The output pipe 35 is inclined downwards towards the sludge tank 13.

[0048] Reference Figure 3 , Figure 6 As the filter cartridge 21 is used, clogging may occur. To address this, in this embodiment, the wastewater tank 12 is equipped with a cleaning component 4 for cleaning the filter cartridge 21. The cleaning component 4 specifically includes a scraper 41, a connecting seat 42, and a second driving component 43. The scraper 41 abuts against the outer peripheral wall of the filter cartridge 21, and its shape is typically an arc shape adapted to the outer peripheral wall of the filter cartridge 21. The material can be rubber or plastic, or other materials with a certain degree of elasticity and wear resistance. The function of the scraper 41 is to scrape away the sludge adhering to the outer peripheral wall of the filter cartridge 21, reducing sludge clogging of the filter cartridge 21's mesh. The connecting seat 42 is fixedly connected to the scraper 41.

[0049] The second driving component 43 drives the connecting seat 42 to reciprocate along the length of the filter cartridge 21. Specifically, it includes a driven gear 431 meshing with the rack 231, a lead screw 432 coaxially connected to the driven gear 431, and a guide rod 433 parallel to the length of the lead screw 432. A rotating plate 242 is provided inside the U-shaped cover 24, allowing the other end of the lead screw 432 to be rotatably connected to the other end of the guide rod 433. It should be noted that the lead screw 432 can be a one-way threaded lead screw 432 or a reciprocating lead screw 432, allowing the scraper 41 to reciprocate during the one-way rotation of the filter cartridge 21. The driven gear 431 meshes with the rack 231; when the rack 231 rotates, the driven gear 431 rotates accordingly, thereby driving the lead screw 432 to rotate. The lead screw 432 and the connecting seat 42 are threaded together; when the lead screw 432 rotates, the connecting seat 42 reciprocates along the length of the lead screw 432. The guide rod 433 slides through the connecting seat 42 to serve as a guide and ensure the stability of the movement of the connecting seat 42.

[0050] The implementation principle of the wastewater treatment device for water supply and drainage with easy sludge discharge according to an embodiment of this application is as follows: This wastewater treatment device uses a separation component 2 to separate the wastewater and sludge mixture through the cooperation of a filter cartridge 21 and a spiral steel beam 22. Wastewater flows out through the filter cartridge 21, while the sludge is pushed by the spiral steel beam 22 to the input component 3 and then enters the sludge tank 13, achieving efficient separation of sludge and wastewater. Simultaneously, the cleaning component 4 can clean the filter cartridge 21 in a timely manner, preventing sludge blockage and extending the service life of the filter cartridge 21, thereby improving the efficiency of wastewater treatment.

[0051] Example 2:

[0052] Reference Figure 7 , Figure 8 The difference from Embodiment 1 is that the cleaning assembly 4 further includes a water spray pipe 44 connected to the connecting seat 42, a water pipe 45 connected to the water spray pipe 44, and a water pump 46 connected to the water pipe 45. In this embodiment, the water spray pipe 44 is arc-shaped and coaxially arranged with the filter cartridge 21. Several water outlet holes 441 are provided on the surface of the water spray pipe 44 near the filter cartridge 21. The water pump 46 is built into the sewage tank 12, and the water pipe 45 is a corrugated flexible hose. When the water pump 46 is started, sewage is drawn and transported through the water pipe 45 to the water spray pipe 44, and then sprayed out from the water outlet holes 441 of the water spray pipe 44 to rinse the filter cartridge 21.

[0053] The spacing between several water outlets 441 can be gradually reduced in the direction away from the water pipe 45 to improve the uniformity of water spray.

[0054] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
