Abstract
Description
Technical Field
[0001] This utility model relates to the field of water treatment filtration technology, and in particular to a filtration device for water treatment. Background Technology
[0002] Wastewater treatment typically includes processes such as pretreatment, biological treatment, sedimentation, and disinfection. Pretreatment is the foundation of wastewater treatment, primarily filtering out solid waste, small floating objects, and particulate impurities. Currently, smaller filter pores are more effective at filtering impurities in wastewater treatment, but they are also more prone to clogging. Therefore, the filtration equipment needs to be stopped periodically to clean the filter pores, which affects filtration efficiency.
[0003] Existing technologies also include some water treatment filtration devices, such as the Chinese utility model patent with application number CN202422480895.5, entitled "Anti-clogging Filtration Device for Industrial Wastewater Treatment." This device controls the rotation of the rotary filter assembly to dislodge blockages, thus preventing clogging and quickly and efficiently resolving over-clogging. However, when particulate impurities cause clogging, centrifugal rotation alone is insufficient to dislodge the blockages, and the dislodged blockages remain inside the filter cartridge, easily leading to re-clogging.
[0004] For example, Chinese utility model patent application number CN202420675191.0, entitled "Anti-clogging Filter Device for Water Treatment," uses an exhaust port to continuously blow and churn impurities in the water above the filter plate upwards, preventing them from clogging the filter plate and achieving a good anti-clogging effect. However, it also fails to remove the blockage material, leaving it in the filter tank, making it prone to clogging again. Utility Model Content
[0005] In order to overcome the shortcomings of the prior art, the purpose of this utility model is to provide a water treatment filtration device that can continuously clean the blockage in the filter holes without stopping the machine and remove it from the filter cartridge, thereby eliminating the blockage and preventing the same blockage from clogging the filter cartridge again, resulting in higher filtration efficiency.
[0006] This utility model is achieved using the following technical solution: a water treatment filtration device, comprising a filtration chamber, an inlet chamber, a drive assembly, a filtration structure, and a flushing structure. Both the filtration chamber and the inlet chamber are equipped with inlet and outlet pipes. An outlet is provided between the filtration chamber and the inlet chamber. The filtration structure is disposed within the filtration chamber. The drive assembly drives the filtration structure to rotate. The flushing structure is disposed above the filtration structure. Wastewater flows into the inlet chamber through the inlet and outlet pipes at the bottom of the inlet chamber and enters the filtration chamber through the outlet. The drive assembly drives the filtration structure to rotate, filtering the incoming wastewater. The filtered wastewater flows out from the inlet and outlet pipes of the filtration chamber. The flushing structure is used to flush the filtration structure.
[0007] Furthermore, the filter structure includes a cover, a filter cylinder, a frame, and a sleeve, wherein the frame is fixed between the cover and the sleeve, and the filter cylinder is sleeved and fixed on the outer ring of the frame.
[0008] Furthermore, the flushing structure includes a flushing tank, a flushing tank support, a flushing tank drain pipe, a flushing pipe, and flushing nozzles. The flushing tank is supported and fixed by the flushing tank support, which is fixed to the inner wall of the front side plate of the water inlet chamber by bolts. The flushing tank drain pipe is located at the bottom front of the flushing tank. The flushing pipe is horizontally installed at the upper end of the filter chamber. Multiple flushing nozzles are evenly spaced on the flushing pipe, and the flushing nozzles are located above the filter cylinder.
[0009] Furthermore, the rear end of the flushing tank extends into the rear end of the filter cartridge, and the front end of the flushing tank extends into the front of the water inlet chamber.
[0010] Furthermore, the rinsing tank is inclined forward, so that the rinsing liquid in the rinsing tank flows forward and is discharged from the rinsing tank drain pipe.
[0011] Furthermore, the drive assembly includes a geared motor, a bearing housing, and a rotating shaft. The geared motor is fixed to the outside of the water inlet chamber, the bearing housing is fixed to the rear side plate of the water inlet chamber, and the rotating shaft is rotatably mounted in the bearing housing. The rear end of the rotating shaft is connected and fixed to the shaft of the geared motor, and the front end of the rotating shaft is connected to the center of the cylinder cover.
[0012] Furthermore, a rotating frame is symmetrically fixed to the rear side plate of the water inlet chamber by bolts, and a rotating wheel is rotatably installed at the bottom end of the rotating frame, and the rotating wheel is in rolling engagement with the inner wall of the sleeve.
[0013] Furthermore, the filter cylinder is cylindrical, with multiple annular filter holes evenly and at intervals on it.
[0014] Furthermore, the inlet and outlet water pipes installed on the filter chamber are located at its rear bottom end.
[0015] Furthermore, the sleeve front end is integrally formed with a sleeve ring, and the front end of the rotating wheel is provided with a wheel groove, which fits into the sleeve ring, so that the rotating wheel is blocked and limited by the sleeve ring.
[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0017] 1. The present invention relates to a water treatment filtration device in which wastewater to be filtered flows into the inlet chamber through the inlet and outlet pipes at the bottom of the inlet chamber, and after being collected in the inlet chamber, enters the filtration structure through the outlet. The cylindrical filter cylinder is used to filter the wastewater, which can filter floating matter and particulate impurities in the wastewater with high filtration efficiency.
[0018] 2. The water treatment filtration device of this utility model uses the flushing nozzle in the flushing structure to flush the filter holes on the filter cylinder, flushing out the clogging impurities in the filter holes and letting them fall into the flushing tank below, and then being discharged from the flushing tank drain pipe with the water flow. This allows for continuous, non-stop cleaning of the filter holes and removes the clogging material from the filter cylinder, eliminating blockages and avoiding the situation in the prior art where the same clogging material is easily adsorbed again after cleaning and clogs the filter cylinder, thus ensuring the filtration effect.

Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.
[0028] The purpose of this invention is to address the shortcomings of existing technologies by providing a filtration device for water treatment.
[0029] Example 1
[0030] This embodiment provides a water treatment filtration device, referring to... Figures 1-3 As shown, the system includes a filter chamber 1, an inlet chamber 2, a drive assembly 3, a filter structure 4, and a flushing structure 5. Both the filter chamber 1 and the inlet chamber 2 are equipped with inlet and outlet pipes 21. The inlet and outlet pipes 21 on the filter chamber 1 are located at its rear bottom for easy drainage of filtered water. An outlet 11 is provided between the filter chamber 1 and the inlet chamber 2, connecting to the front of the filter structure 4. Water to be filtered collects in the inlet chamber 2 and enters the filter structure 4 through the outlet 11. The filter structure 4 is located inside the filter chamber 1. The drive assembly 3 drives the filter structure 4 to rotate, and the flushing structure 5 is located above the filter structure 4. Wastewater flows into the inlet chamber 2 through the inlet and outlet pipes 21 at the bottom of the inlet chamber 2 and enters the filter chamber 1 through the outlet 11. The drive assembly 3 drives the filter structure 4 to rotate, filtering the incoming wastewater. The filtered wastewater flows out from the inlet and outlet pipes 21 on the filter chamber 1. The flushing structure 5 flushes the filter structure 4 to prevent clogging.
[0031] Reference Figures 2-4As shown, the drive assembly 3 includes a geared motor 31, a bearing housing 32, and a rotating shaft 33. The geared motor 31 is fixed on the outside of the water inlet chamber 2. In this embodiment, the geared motor 31 is a DC geared motor in the prior art. The bearing housing 32 is fixed on the rear side plate of the water inlet chamber 2. The rotating shaft 33 is rotatably installed in the bearing housing 32. The rear end of the rotating shaft 33 is connected and fixed to the shaft of the geared motor 31, and the front end of the rotating shaft 33 is connected to the center of the cylinder cover 41, driving it to rotate.
[0032] Reference Figures 4-6 As shown, the filter structure 4 includes a cover 41, a frame 42, a filter cylinder 43, and a sleeve 44. The frame 42 is fixed between the cover 41 and the sleeve 44, and the filter cylinder 43 is fitted and fixed on the outer ring of the frame 42. In this embodiment, the filter cylinder 43 is cylindrical, with multiple annular filter holes evenly spaced on it. The size of the annular filter holes can be selected according to the condition of the wastewater to be filtered. The size should not be too large. Preferably, the width of the annular filter holes is 1cm to 6cm. When there are many floating objects and large impurities in the wastewater to be filtered, the size of the annular filter holes can be appropriately increased.
[0033] Reference Figures 6-7 As shown, two rotating wheel frames 45 are symmetrically fixed to the rear side plate of the water inlet chamber 2 by bolts. A rotating wheel 46 is rotatably mounted on the bottom end of each of the two rotating wheel frames 45, and the rotating wheel 46 rolls in contact with the inner wall of the sleeve 44. Specifically, in this embodiment, a sleeve ring 441 is integrally formed at the front end of the sleeve 44, and a wheel groove is provided at the front end of the rotating wheel 46. The wheel groove of the rotating wheel 46 fits against the sleeve ring 441, so that the rotating wheel 46 is blocked and limited by the sleeve ring 441.
[0034] This utility model discloses a water treatment filtration device. In use, wastewater to be filtered flows into the inlet / outlet pipe 21 at the bottom of the inlet chamber 2. After converging in the inlet chamber 2, it enters the filter structure 4 through the outlet 11. A cylindrical filter cylinder 43 filters the wastewater, removing floating matter and particulate impurities, thus achieving preliminary filtration. During this process, a reduction motor 31 drives the cylinder cover 41 to rotate via a rotating shaft 33. The front end of the filter structure 4 rotates through a rolling engagement between a rotating wheel 46 and the inner wall of the sleeve 44, while the rear end rotates via the rotating shaft 33 within a bearing seat 32. This rotation of the filter cylinder 43 filters the wastewater, preventing floating matter and particulate impurities from adhering and blocking the filter holes.
[0035] Example 2
[0036] This embodiment provides a water treatment filtration device, which is based on the structure in Embodiment 1, and refers to... Figures 3-4As shown, the rinsing structure 5 includes a rinsing tank 51, a rinsing tank support 52, a rinsing tank drain pipe 53, a rinsing pipe 54, and rinsing nozzles 55. The rinsing tank 51 is supported and fixed by the rinsing tank support 52. The rear end of the rinsing tank 51 extends to the rear end of the filter cartridge 43, and the front end of the rinsing tank 51 extends to the front of the water inlet chamber 2. The rinsing tank support 52 is fixed to the inner wall of the front side plate of the water inlet chamber 2 by bolts. The rinsing tank drain pipe 53 is located at the bottom front end of the rinsing tank 51. The rinsing pipe 54 is horizontally installed at the upper end of the filter chamber 1. One end of the rinsing pipe 54 is connected to the pressurized water flow, and the other end is sealed. Multiple rinsing nozzles 55 are evenly spaced on the rinsing pipe 54. The rinsing nozzles 55 are located above the filter cartridge 43, and the rinsing tank 51 is located below the rinsing nozzles 55.
[0037] To ensure filtration efficiency, the filter holes on the filter cartridge 43 should not be too large. However, smaller filter holes are more easily clogged by particulate matter and other impurities in the wastewater, affecting filtration. The filter cartridge 43 is rotated at a constant speed by a geared motor 31, and flushed by a row of flushing nozzles 55 in the flushing structure 5. This flushes out the blockages in the filter holes of the filter cartridge 43, causing them to fall into the flushing tank 51 below and be discharged from the flushing tank drain pipe 53 with the water flow. This allows for continuous, non-stop cleaning of the filter holes, removing the blockages from the filter cartridge 43, eliminating blockages, ensuring filtration efficiency, and achieving high filtration performance.
[0038] Furthermore, referring to Figure 4 As shown, in this embodiment, the rinsing tank 51 is inclined forward, which allows the rinsing liquid in the rinsing tank 51 to flow forward better, and helps the clogging impurities flushed out to be discharged more smoothly from the rinsing tank drain pipe 53.
[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
