Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment, and specifically to a portable filter cloth cleaning device. Background Technology

[0002] Primary sedimentation tanks are the first-stage treatment unit in wastewater treatment processes. They remove approximately 30% to 50% of suspended solids from wastewater through gravity settling, reducing the load on subsequent treatment processes. Some primary sedimentation tanks are equipped with filtration devices (sloping frame plate sedimentation tank + filter cloth) to enhance solid-liquid separation efficiency. During use, colloidal particles can adhere to the surface of the filter cloth, causing clogging and affecting the filtration effect.

[0003] Currently, nozzles are installed at both ends of the inclined frame plate to rinse the filter cloth. However, the high-pressure water sprayed from the nozzles is insufficient to rinse the middle part of the filter cloth, thus affecting the filtration effect in the middle of the filter cloth. Utility Model Content

[0004] The technical problem this invention aims to solve is that the water sprayed from the high-pressure nozzles at both ends of the inclined plate is difficult to flush away the blockages in the middle of the filter cloth, thus affecting the filtration effect of the middle of the filter cloth. The purpose is to provide a movable filter cloth cleaning device that allows the high-pressure nozzles to flush the middle and any other part of the filter cloth, ensuring the cleaning effect of the filter cloth and thus ensuring the filtration effect of the filter cloth.

[0005] This utility model is achieved through the following technical solution:

[0006] A movable filter cloth cleaning device includes a support block, a hose, and a support rod. A high-pressure nozzle is slidably connected to the support block and can slide along the length of the support block. One end of the hose is connected to a high-pressure water source, and the other end is connected to the high-pressure nozzle. The hose can slide within the support block. The top of the support rod is connected to one end of the support block.

[0007] The beneficial effects of this utility model are that the high-pressure nozzle can slide along the length of the support block, and one end of the hose is connected to a high-pressure water source. The hose can slide inside the support block, and a support rod is connected to one end of the support block. During operation, the support block can be supported by the support rod, allowing the support block to extend into the primary sedimentation tank and be positioned directly opposite the filter cloth. This enables the high-pressure nozzle to rinse the middle and any other part of the filter cloth, ensuring the cleaning effect of the filter cloth and thus ensuring the filtration effect of the filter cloth.

[0008] In some embodiments, the support block is rectangular, and a groove is provided on one side of the support block for the high-pressure nozzle to slide. By making the support block rectangular, it is convenient for the high-pressure nozzle to move along the width of the filter cloth when it moves along the length of the support block, thereby enabling cleaning of various parts of the filter cloth that are moving in a cyclic manner.

[0009] In some embodiments, a receiving cavity is provided in the middle of the support block. The receiving cavity has a rectangular cross-section, and the hose is located inside the receiving cavity. The width of the receiving cavity is greater than three times the outer diameter of the hose. By providing a receiving cavity in the middle of the support block and setting the cross-section of the receiving cavity to be rectangular with a width greater than three times the outer diameter of the hose, sufficient sliding space is provided for the hose when the high-pressure nozzle slides.

[0010] In some embodiments, the high-pressure nozzle includes a connecting part and a nozzle. The connecting part is connected to the water outlet end of the hose, and the nozzle orifice extends out of the support block. Several connector locking grooves are provided on the sidewall of the receiving cavity along its length. These connector locking grooves are located on the sidewall of the sliding groove. In the working state, the end of the high-pressure nozzle where it connects to the nozzle abuts against the sidewall of the connector locking groove. By connecting the connecting part of the high-pressure nozzle to the water outlet end of the hose and extending the nozzle orifice out of the support block, the position of the nozzle is visible during operation, allowing for accurate rinsing of areas on the filter cloth containing adhesive particles. Furthermore, the presence of several connector locking grooves on the sidewall along the length of the receiving cavity facilitates the pressure of the high-pressure water jet during operation, causing the end of the high-pressure nozzle's connecting part (the end where it connects to the nozzle) to abut against the sidewall of the corresponding connector locking groove. This limits the high-pressure nozzle's position and prevents it from rotating during operation, thus ensuring the accuracy of the water spray direction.

[0011] In some embodiments, the length of the nozzle located outside the support block is greater than the length of the connector locking groove. By making the length of the nozzle located outside the support block greater than the length of the connector locking groove, it is convenient to push the nozzle towards the receiving cavity when it is necessary to slide the high-pressure nozzle, so that the connecting part disengages from the connector locking groove, then slide the high-pressure nozzle to the required position, and then pull the nozzle towards the outside of the support plate, so that the connecting part is located in the connector locking groove, thereby limiting the high-pressure nozzle.

[0012] In some embodiments, the cross-section of the connector snap-fit ​​groove is arc-shaped, and several connector snap-fit ​​grooves are evenly distributed along the length direction of the slide groove.

[0013] In some embodiments, the length of the support block is greater than or equal to 2 meters. Since the width of the filter cloth is generally 2 meters, the length of the support block is greater than 2 meters to facilitate rinsing of various parts of the filter cloth.

[0014] In some embodiments, the system further includes an adapter and a steel water pipe. The adapter is threaded to one end of the support block, and one end of the adapter on the support block is connected to the inlet end of the hose. The other end of the adapter is connected to the steel water pipe. By providing the adapter, the steel water pipe and the hose are connected together, allowing high-pressure water to enter the hose. The adapter is also threaded to the support block, connecting the steel water pipe and the hose to the support block.

[0015] In some embodiments, a locking nut is further included, which is screwed onto the outer side of the adapter. In the working state, one end of the locking nut abuts against the support block. By providing the locking nut, the adapter is prevented from rotating during operation.

[0016] In some embodiments, the support rod is circular and vertically connected to the lower end of the support block, with its top threadedly connected to the support block. This threaded connection facilitates replacement and disassembly.

[0017] Compared with the prior art, this utility model has the following advantages and beneficial effects:

[0018] 1. The support block is supported by the support rod, so that the support block can extend into the primary sedimentation tank and be located directly opposite the filter cloth. This allows the high-pressure nozzle to rinse the middle and any other part of the filter cloth, ensuring the cleaning effect of the filter cloth and thus ensuring the filtration effect of the filter cloth.

[0019] 2. Several connector slots are provided on the side wall along the length of the cavity. During operation, the jet force of the high-pressure water causes the end of the high-pressure nozzle (the end that connects with the nozzle) to abut against the side wall of the corresponding connector slot, thereby limiting the high-pressure nozzle and preventing the high-pressure nozzle from rotating during operation, which would affect the accuracy of the water spray direction.

[0030] Example

[0031] like Figures 1-3As shown, this embodiment provides a movable filter cloth cleaning device, including a support block 40, a hose 20, and a support rod 13. A high-pressure nozzle 30 is slidably connected to the support block 40, and the high-pressure nozzle 30 can slide along the length direction of the support block 40. One end of the hose 20 is connected to a high-pressure water source, and the other end is connected to the high-pressure nozzle 30. The hose 20 can slide within the support block 40. The top of the support rod 13 is connected to one end of the support block 40.

[0032] See Figures 1-3 The support block 40 is rectangular in shape, and a groove 43 is provided on one side of the support block 40 for the high-pressure nozzle 30 to slide. By making the support block 40 rectangular, it is convenient for the high-pressure nozzle 32 to move along the length of the filter cloth when it moves along the length of the support block 40, thereby enabling cleaning of various parts of the filter cloth.

[0033] See Figures 1-3 The support block 40 has a receiving cavity 41 in its middle. The receiving cavity 41 has a rectangular cross-section, and the hose 20 is located inside the receiving cavity 41. The width of the receiving cavity 41 is greater than three times the outer diameter of the hose 20. By providing a receiving cavity 41 in the middle of the support block 40 and setting the cross-section of the receiving cavity 41 to be rectangular and the width greater than three times the outer diameter of the hose 20, the hose 20 has sufficient sliding space when the high-pressure nozzle 32 slides.

[0034] See Figures 1-2 The high-pressure nozzle 30 includes a connecting part 31 and a nozzle 32. The connecting part 31 is connected to the water outlet end of the hose 20. The nozzle 32 extends out of the support block 40. Several connector locking grooves 42 are provided on the side wall of the receiving cavity 41 along its length. The connector locking grooves 42 are located on the side wall of the sliding groove 43. In the working state, the end of the high-pressure nozzle 30 where the connecting part 31 and the nozzle 32 are joined abuts against the side wall of the connector locking groove 42. By connecting the connecting part 31 of the high-pressure nozzle 30 to the water outlet end of the hose 20, and extending the nozzle 32's nozzle outlet out of the support block 40, the position of the nozzle 32 can be seen during operation, allowing for accurate rinsing of the filter cloth with adhesive particles. Several connector slots 42 are also provided on the side wall along the length of the receiving cavity 41, so that during operation, the jet force of the high-pressure water causes the end of the connecting part 31 of the high-pressure nozzle 30 (the end where it connects with the nozzle 32) to abut against the side wall of the corresponding connector slot 42, thereby limiting the high-pressure nozzle 30 and preventing the high-pressure nozzle 32 from rotating during operation, which would affect the accuracy of the water spray direction.

[0035] See Figure 2The nozzle 32 located outside the support block 40 is longer than the connector locking groove 42. By making the nozzle 32 located outside the support block 40 longer than the connector locking groove 42, it is convenient to push the nozzle 32 towards the receiving cavity 41 when it is necessary to slide the high-pressure nozzle 30, so that the connecting part 31 disengages from the connector locking groove 42, then slide the high-pressure nozzle 30 to the required position, and then pull the nozzle 32 towards the outside of the support plate, so that the connecting part 31 is located in the connector locking groove 42, thus limiting the high-pressure nozzle 32.

[0036] See Figures 1-3 It also includes an adapter 11 and a steel water pipe 10. The adapter 11 is threadedly connected to one end of the support block 40. One end of the adapter 11 on the support block 40 is connected to the inlet end of the hose 20, and the other end of the adapter 11 is connected to the steel water pipe 10. By setting the adapter 11 to connect the steel water pipe 10 and the hose 20, high-pressure water can enter the hose 20. The adapter 11 is also threadedly connected to the support block 40, connecting the steel water pipe 10 and the hose 20 to the support block 40.

[0037] See Figures 1-3 It also includes a locking nut 12, which is screwed onto the outer side of the adapter 11. In the working state, one end of the locking nut 12 abuts against the support block 40. By providing the locking nut 12, the adapter 11 is prevented from rotating during operation.

[0038] See Figures 1-3 The support rod 13 is circular and vertically connected to the lower end of the support block 40. The top of the support rod 13 is threaded to the support block 40. The threaded connection between the support rod 13 and the support block 40 facilitates replacement and disassembly.

[0039] During operation, the filter cloth continuously moves in a circular motion along the width of the inclined frame plate. Therefore, during operation, first slide the high-pressure nozzle 30 and snap it into the corresponding position, and then position the support rod 13 on the side wall of the primary sedimentation tank. Alternatively, the operator can hold the support rod 13 and place the support plate directly opposite the filter cloth, turn on the high-pressure water source, and spray water from the high-pressure nozzle 30 to rinse the areas on the filter cloth with colloidal particles.

[0040] The specific embodiments described above further illustrate the purpose, technical solution, and beneficial effects of this utility model. It should be understood that the above description is only a specific embodiment of this utility model and is not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
