Description

Technical Field

[0001] The invention relates to the technical field of rotary filter screens, in particular to an ultra-deep rotary filter screen. Background Art

[0002] The rotary filter is a commonly used sewage treatment equipment, mainly used to remove solid particles in wastewater or sewage. The rotary filter can filter continuously and quickly remove suspended matter, floating matter, etc. in sewage to ensure the quality of the effluent. When the fluid containing solid particles passes through the filter, the solid particles are intercepted by the filter and remain on the filter, while the clean fluid continues to flow through the filter. The rotation of the filter can prevent the filter from being completely blocked.

[0003] Considering that the filter in the prior art lacks cleaning treatment for impurities, when the internal impurities increase, the filter may be blocked. Since the filter is rotating, partial blockage will not affect the filtering effect during initial use, but after long-term use, the filter will be blocked to varying degrees, which may cause the filtering effect to deteriorate. In severe cases, it may lead to failure to filter. The prior art uses an inclined filter to discharge internal impurities, but impurities larger than the pores of the filter may fail to adhere to the filter, causing the impurities to slip and accumulate at the bottom of the equipment. Summary of the invention

[0004] The object of the present invention is to provide an ultra-deep rotary filter to solve the problems raised in the above background technology.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is an ultra-deep rotary filter, comprising a filter housing, a console fixedly connected to the top of the filter housing, a filtering mechanism arranged inside the filter housing, water outlets arranged on two corresponding side surfaces of the filter housing, waist-shaped grooves arranged on the other two side surfaces of the filter housing, and the waist-shaped grooves are used for water inlet; a driving motor fixedly connected to the top of the filter housing, and the driving motor is used to drive the filtering mechanism; The inner wall of one of the waist-shaped grooves is slidably connected with a driving chain, and the inner wall of the other waist-shaped groove is slidably connected with a limiting chain, and the driving chain and the limiting chain are both in contact with the inner wall of the waist-shaped groove; a sprocket is meshed on the side of the driving chain close to the driving motor, and a sprocket is meshed on the side of the driving chain away from the driving motor; the inner walls of the sprockets are fixedly connected with a rotating shaft, and a protective shell is provided on the side of the filter housing close to the sprocket, and the protective shell is used to prevent sewage impurities from entering the sprocket and the driving chain, and the rotating shaft is rotatably connected to the side of the protective shell close to the filter housing; the rotating shaft close to the driving motor is transmission-connected to the output shaft of the driving motor through a transmission belt; The filter mechanism comprises a filter body, one side of the filter body is fixedly connected to a driving chain, and the other side of the filter body is fixedly connected to a limiting chain, and the inner wall of the filter body close to a sprocket is slidably connected with a positioning plate, and the positioning plate is rotatably connected to a rotating shaft; the inner wall of the other side of the filter body is slidably connected with a limiting plate, the limiting plate is rotatably connected to the rotating shaft, a water inlet is provided on the surface of the limiting plate, and the water inlet is connected to the waist-shaped groove; the positioning plate and the limiting plate are both used for supporting and limiting the filter body; the surface of the filter body close to the positioning plate and the limiting plate is provided with a sliding groove, and the sliding groove runs through the filter body, and the inner wall of the sliding groove is hinged with a collecting block, the bottom of the collecting block is hinged to the inner surface of the filter body, and a plurality of collecting blocks are arranged around the filter body; the collecting block is used to collect impurities, and the side of the collecting block that is in contact with the filter body is open, and there is an opening at the top.

[0006] By adopting the above technical solution, the driving motor is started after the sewage enters the equipment from the water inlet. At this time, the filter body will be driven, and the sewage can be filtered through the filter holes on the filter body. In order to prevent the problem of clogging of the filter body due to excessive impurities, a collecting block is provided on the filter body to remove impurities in the water. When the collecting block is at the bottom of the filter body, the impurities that have settled to the bottom can be removed to prevent the bottom impurities from entering the filter holes of the filter body and causing blockage.

[0007] Furthermore, the inner walls of the sliding grooves are slidably connected with pressure blocks; the sides of each of the two pressure blocks away from the filter housing are fixedly connected to the two ends of the collecting blocks close to the filter housing; the side of the pressure block close to the top of the filter housing is slidably connected to the top of the inner wall of the filter housing; the side of the pressure block close to the filter body is fixedly connected with a return spring, and the end of the return spring away from the pressure block is fixedly connected to the filter body; the side of the pressure block away from each other is slidably connected to the inner wall of the filter housing.

[0008] By adopting the above technical scheme, the pressure block can move along the inner wall of the filter body when it contacts the top of the filter shell, and because the collecting block is hinged to the filter body, only the inclined part of the collecting block can squeeze the collecting block inward, thereby increasing the angle of the collecting block close to the top. After the angle is increased, the internal impurities can slide along the inner wall of the collecting block, and the internal impurities can be concentrated by setting a collection box; when the impurities are collected and the collecting block runs to the downward position, the pressure block will be reset by the reset spring when the squeeze of the filter shell is lost, and prepare for the next reset operation.

[0009] Furthermore, two support blocks are symmetrically fixedly connected to one side of the positioning plate close to the limiting plate, and two support blocks are symmetrically fixedly connected to one side of the limiting plate close to the positioning plate, and the support blocks are all located above the rotating shaft; sliding holes are provided on the inner walls of the two support blocks close to the positioning plate, and a shaking rod is slidably connected to the inner walls of the sliding holes, and a sewage discharge box is fixedly connected to the top of the shaking rod; a shaking block is fixedly connected to one end of the rotating shaft close to the support block, and there are multiple shaking blocks.

[0010] By adopting the above technical scheme, impurities can be collected through the setting of the sewage box, and the shaking block and the sewage box are repeatedly contacted when the rotating shaft rotates. Since the shaking block is only set at one end of the rotating shaft, only one end of the sewage box will be repeatedly lifted up by the shaking block. The sewage box is shaken by the repeated lifting of the shaking block, and the impurities inside the sewage box are flattened so that it can accommodate more impurities. At the same time, by shaking only one side of the sewage box, the impurities can be moved to the other side of the sewage box through the shaking and discharged through the sewage outlet.

[0011] Furthermore, a sewage outlet is provided on the surface of the limiting plate close to the top of the rotating shaft, and the outer wall of the sewage outlet box is slidably connected to the inner wall of the sewage outlet.

[0012] By adopting the above technical solution, impurities inside the sewage box can be discharged through the setting of the sewage outlet, and when the equipment is shut down and does not run for a long time, the sewage box can be directly taken out and the impurities inside the sewage box can be poured out to ensure that no stains remain on the surface of the sewage box, so as to prevent rust or corrosion due to a long time.

[0013] Furthermore, a waterproof baffle is symmetrically fixedly connected to the outer wall of the filter body close to the collecting block, and the outer wall of the waterproof baffle is fixedly connected to the inner wall of the filter housing.

[0014] By adopting the above technical solution, the waterproof baffle can be set to prevent water from entering the interior of the equipment. If water enters, it may cause rust or corrosion. The waterproof baffle can also be set together with the filter housing to limit the position of the pressing block to prevent the pressing block from leaving its original position. By limiting the position of the pressing block, the position of the filter body can also be indirectly restricted.

[0015] Furthermore, a stopper is symmetrically fixedly connected to the inner wall of the filter housing near the top of the water outlet, and a side of the stopper near the filter body is slidably connected to the filter body.

[0016] By adopting the above technical solution, the setting of the block can prevent water or impurities that do not need to be cleaned from moving upward through the filter body to the inside of the device, so as to prevent water from re-entering the device at the top of the device, which will not only cause waste of energy, but also cause water to fall into the inside of the drain box, causing water to be discharged from the device along the drain box, resulting in a waste of water resources.

[0017] Furthermore, a mounting plate is fixedly connected to the outer wall of the filter housing close to the top of the water outlet, and an inner wall of the mounting plate close to the driving chain is slidably connected to the driving chain.

[0018] By adopting the above technical solution, since the rotary filter usually needs to be partially placed underground, the equipment can be fixed on the ground by setting a mounting plate. The equipment on the mounting plate can be used to control and clean the equipment, while the equipment under the mounting plate will be placed in the sewage for filtering operations.

[0019] Furthermore, a side of the limit plate close to the filter housing is fixedly connected to a limit baffle, and an outer wall of the limit baffle is slidably connected to an inner wall of the limit chain.

[0020] By adopting the above technical solution, since the limit chain itself is used to position or limit the filter body, the limit chain itself will be transmitted along with the filter body. If the position of the limit chain falls off, the equipment may be damaged. The limit plate can limit the limit chain through the limit baffle while limiting the rotating shaft. Since a water inlet is provided on the surface of the limit plate, the strength of the limit plate itself will be reduced. By setting the limit baffle, the edge of the limit plate can be strengthened so that the limit plate can withstand greater stress.

[0021] The present invention has the following beneficial effects: 1. The present invention starts the driving motor after the sewage enters the device from the water inlet, at which time the filter body will be driven, and the sewage can be filtered through the filter holes on the filter body; in order to prevent the problem of excessive impurities causing blockage of the filter body, a collecting block is provided on the filter body to remove impurities in the water, and when the collecting block is at the bottom of the filter body, the impurities that have settled to the bottom can be removed to prevent the bottom impurities from entering the filter holes of the filter body and causing blockage.

[0022] 2. When removing impurities, the present invention can move along the inner wall of the filter body when the pressing block contacts the top of the filter shell, and because the collecting block is hinged to the filter body, only the inclined portion of the collecting block can squeeze the collecting block inward, thereby increasing the angle of the collecting block close to the top. After the angle is increased, the internal impurities can slide along the inner wall of the collecting block and be collected when the impurities fall. Due to the small gap between the pressing block and the top of the filter shell, the impurities will not be discharged until the pressing block and the collecting block reach the top of the equipment, thereby preventing the impurities from falling into the water repeatedly, resulting in multiple operations required to collect the impurities.

[0023] 3. When the impurities need to be collected, the sewage box needs to be placed in the equipment. Since the shaking block is only arranged at one end of the rotating shaft, only one end of the sewage box will be repeatedly lifted up when the rotating shaft rotates. The sewage box is repeatedly lifted up by the shaking block to shake it and spread the impurities inside the sewage box so that it can accommodate more impurities. At the same time, by shaking only one side of the sewage box, the impurities can be moved to the other side of the sewage box through the shaking and discharged through the sewage outlet.

The inner wall of the filter body 21 near the sprocket 15 is slidably connected with a positioning plate 18, and the positioning plate 18 is rotatably connected to the rotating shaft 14; the inner wall of the other side of the filter body 21 is slidably connected with a limit plate 19, and the limit plate 19 is rotatably connected to the rotating shaft 14. A water inlet is opened on the surface of the limit plate 19, and the water inlet is connected to the waist-shaped groove; the positioning plate 18 is slidably connected to the inner wall of the other side of the filter body 21, and the limit plate 19 is rotatably connected to the rotating shaft 14. The plate 18 and the limiting plate 19 are both used for supporting and limiting the filter body 21; the surface of the filter body 21 close to the positioning plate 18 and the limiting plate 19 is provided with a sliding groove, and the sliding groove runs through the filter body 21, the inner wall of the sliding groove is hinged with a collecting block 28, the bottom of the collecting block 28 is hinged to the inner surface of the filter body 21, and a plurality of collecting blocks 28 are arranged around the filter body 21; the collecting block 28 is used to collect impurities, the side of the collecting block 28 that is in contact with the filter body 21 is open, and there is an opening on the top.

[0029] In this embodiment, considering that the filter in the prior art lacks cleaning treatment for impurities, when the impurities inside increase, the filter may be blocked. Since the filter is rotating, partial blockage will not affect the filtering effect in the initial use, but after long-term use, the filter will be blocked to varying degrees, which may cause the filtering effect to deteriorate, and in severe cases, may cause the filtering to fail. In the prior art, a rotary filter screen with the publication number of CN116585788A is used. When in use, the reduction motor is controlled to work, so that the rotating shaft drives the sprocket to rotate, thereby rotating the chain. The rotation of the chain drives the L-shaped mounting member on the chain to rotate in an annular manner. The rotation of the L-shaped mounting member drives the first filter screen plate to rotate, and the smaller debris and floating objects of aquatic plants in the sewage are lifted and separated from the sewage through the inclined second filter screen plate, and then fall into the collection box and discharged through the knocking of the auxiliary cleaning mechanism; in the prior art, the second filter screen plate is tilted to remove the debris in the water, but when encountering impurities larger than the pores of the filter screen, the impurities cannot be attached to the filter screen, and at this time, they may slide down due to the tilt of the second filter screen plate, which may cause the accumulation of impurities at the bottom, and when the equipment needs to purify a large amount of water, it needs to be used in a deeper scene, and the impurities on the second filter screen plate may fall due to partial shaking or vibration during the operation of the equipment, which may also cause the accumulation of impurities at the bottom, resulting in the deterioration of the filtering efficiency of the equipment; In order to solve the above problem, after the sewage enters the device, the drive motor 12 is started, and the drive motor 12 transmits power to the rotating shaft 14 near the top of the device through the transmission belt 13, and the sprocket 15 is rotated by the rotation of the rotating shaft 14. At this time, the engagement of the sprocket 15 with the driving chain 16 will drive the driving chain 16 to transmit, and the rotating shaft 14 and the sprocket 15 near the bottom of the device are matched and limited with the driving chain 16. When the driving chain 16 is transmitted, it will drive the filter body 21 to move synchronously. At this time, the sewage can be filtered through the filter holes on the filter body 21; in order to prevent the problem of the filter body 21 being blocked by excessive impurities The problem arises. By arranging a collecting block 28 on the filter body 21, impurities in the water can be removed. When the collecting block 28 is at the bottom of the filter body 21, the impurities that sink to the bottom can be removed to prevent the impurities at the bottom from entering the filter holes of the filter body 21 and causing blockage. The collecting block 28 will take the water away when discharging water, and filter the water out of the device through the filter holes where the collecting block 28 and the filter body 21 fit. After the collecting block 28 takes water, the water in the center of the water surface will fill out, so that the impurities floating in the center of the water surface can also be removed to prevent the internal impurities from continuing to accumulate. This method can also remove the impurities suspended in the water. Considering that in the prior art, impurities attached to the surface of the filter are removed by cleaning the first filter screen and the second filter screen through nozzles on the first flushing pipe and the second flushing pipe; however, a high-pressure water pump is required when using the nozzle, which increases energy consumption during use. At the same time, the source of the water sprayed by the nozzle, if purified water is used, the clean water will enter the equipment and be re-filtered, resulting in a waste of energy. If unpurified sewage is used, fine particles in the sewage may enter the interior of the nozzle and clog the nozzle; therefore, the device surrounds the nozzle through the collection block 28 The filter body 21 is provided with a plurality of collecting blocks 28, one side of the filter body 21 is opened upward, and the other side is opened downward. During operation, the collecting block 28 with the opening upward will bring out some water, and after the water is brought out, the water inside will fill the vacancy here and flow toward the filter body 21. At the same time, the collecting block 28 with the opening downward will impact the water surface when entering the water surface, and the water inside the collecting block 28 will be impacted and enter the inside of the collecting block 28, and at the same time, a reaction force will be generated on the collecting block 28 and the filter body 21, and the blockage of the filter hole can be cleared by utilizing the reaction force of the water; Considering that the prior art chooses to immerse the sprocket 15 and the drive chain 16 directly in water to facilitate the operation of the equipment, but long-term immersion in water will inevitably cause corrosion and rust. In order to reduce the occurrence of corrosion and rust, the positioning plate 18 can be used to block the water flow, but because the positioning plate 18 is used to support the filter body 21, it will slide with the filter body 21 during use, and it is inevitable that part of the water flow will contact the sprocket 15 and the drive chain 16. The setting of the positioning plate 18 can block part of the water flow from contacting the sprocket 15 and the drive chain 16 to reduce the occurrence of corrosion and rust and increase the service life of the equipment; at the same time, the positioning plate 18 can block large particles in the water. During the operation of the sprocket 15 and the drive chain 16, if harder particles such as stones flow to the gap between the sprocket 15 and the drive chain 16, they may collide and squeeze. If this happens multiple times, it may cause dents or cracks on the surface of the sprocket 15 and the drive chain 16, affecting the service life of the equipment.

[0030] Specifically, the inner wall of the sliding groove is slidably connected with a pressure block 22; the side of each two pressure blocks 22 away from the filter housing 1 is fixedly connected to the two ends of the collecting block 28 close to the filter housing 1; the side of the pressure block 22 close to the top of the filter housing 1 is slidably connected to the top of the inner wall of the filter housing 1; the side of the pressure block 22 close to the filter body 21 is fixedly connected with a return spring 23, and the end of the return spring 23 away from the pressure block 22 is fixedly connected to the filter body 21; the side of the pressure block 22 away from the pressure block is slidably connected to the inner wall of the filter housing 1.

[0031] In this embodiment, considering that only concentrating the impurities inside the device without discharging them may cause the device to become clogged after the device is used for a long time, the pressing block 22 can move along the inner wall of the filter body 21 when it contacts the top of the filter housing 1, and since the collecting block 28 is hinged to the filter body 21, only the inclined surface of the collecting block 28 can press the collecting block 28 inward, thereby increasing the angle of the collecting block 28 near the top, and the increased angle can make the internal impurities slide along the inner wall of the collecting block 28, and by setting the collecting box The internal impurities are concentrated; when the pressing block 22 operates normally, the impurities will be retained in the collecting block 28. When the pressing block 22 and the collecting block 28 reach the top of the filter housing 1, the pressing block 22 and the collecting block 28 will be pressed down. The impurities will not be discharged until the collecting block is pressed down to a certain angle, thereby preventing the impurities from repeatedly falling into the water, resulting in multiple operations required to collect the impurities. When the impurities are collected, when the collecting block 28 runs to the downward position and loses the squeezing of the filter housing 1, the pressing block 22 will be reset through the reset spring 23, and prepare for the next reset operation.

[0032] Specifically, two support blocks 25 are symmetrically fixedly connected to one side of the positioning plate 18 close to the limiting plate 19, and two support blocks 25 are symmetrically fixedly connected to one side of the limiting plate 19 close to the positioning plate 18, and the support blocks 25 are all located above the rotating shaft 14; sliding holes are provided on the inner walls of the two support blocks 25 close to the positioning plate 18, and a shaking rod is slidably connected to the inner wall of the sliding hole, and a sewage box 26 is fixedly connected to the top of the shaking rod; a shaking block is fixedly connected to one end of the rotating shaft 14 close to the support block 25, and there are multiple shaking blocks.

[0033] In this embodiment, the above technical solution is adopted. Considering that in the prior art, multiple collection boxes are arranged inside the device, when a large amount of sewage needs to be treated and applied in a deeper scene, it is troublesome to take out the collection box. In addition, in the prior art, the collection box needs to be manually taken out and cleaned after it is full, which consumes a certain amount of manpower. If it is not cleaned in time, impurities will overflow and fall back into the sewage, and the subsequent filtering operations will be useless operations, which not only consumes energy but also fails to effectively treat the sewage. When it is necessary to collect impurities, the sewage box 26 needs to be placed in the equipment, and the impurities can be collected by the setting of the sewage box 26, and the shaking block is repeatedly in contact with the sewage box 26 when the rotating shaft 14 rotates. Since the shaking block is only set at one end of the rotating shaft 14, only one end of the sewage box 26 will be repeatedly lifted up by the shaking block. The sewage box 26 is shaken by the repeated lifting of the shaking block, and the impurities inside the sewage box 26 are flattened so that it can accommodate more impurities. At the same time, by shaking only one side of the sewage box 26, the impurities can be moved to the other side of the sewage box 26 through shaking and discharged through the sewage outlet. In the process of filtering water by the collecting block 28 and the filter body 21, some water will adhere to the surface of the collecting block 28 and impurities. When the collecting block 28 pours out impurities into the drain box 26, some water will also be poured out. The water on the surface of the drain box 26 can be repeatedly swung back and forth by vibration to remove impurities such as mud and sand attached to the surface of the drain box 26.

[0034] Furthermore, a sewage outlet is provided on the surface of the limiting plate 19 close to the top of the rotating shaft 14 , and the outer wall of the sewage box 26 is slidably connected to the inner wall of the sewage outlet.

[0035] Specifically, a sewage outlet is provided on the surface of the limiting plate 19 near the top, and the outer wall of the sewage box 26 is slidably connected to the inner wall of the sewage outlet.

[0036] In this embodiment, impurities inside the sewage box 26 can be discharged through the setting of the sewage outlet, and when the equipment is shut down and does not operate for a long time, the sewage box 26 can be directly taken out and the impurities inside the sewage box 26 can be poured out to ensure that no stains remain on the surface of the sewage box 26, so as to prevent rust or corrosion due to a long time.

[0037] Specifically, the outer wall of the filter body 21 close to the collecting block 28 is symmetrically fixedly connected with a waterproof baffle 24 , and the outer wall of the waterproof baffle 24 is fixedly connected to the inner wall of the filter housing 1 .

[0038] In this embodiment, the waterproof baffle 24 can prevent water from entering the interior of the device. If water enters, it may cause rust or corrosion. The waterproof baffle 24 can also limit the position of the pressing block 22 together with the filter housing 1 to prevent the pressing block 22 from leaving its original position. By limiting the position of the pressing block 22, the position of the filter body 21 can also be indirectly restricted.

[0039] Specifically, a stopper 27 is symmetrically fixedly connected to the inner wall of the filter housing 1 near the top of the water outlet, and a side of the stopper 27 near the filter body 21 is slidably connected to the filter body 21 .

[0040] In this embodiment, the setting of the block 27 can prevent the clean water from passing through the filter body 21 and moving upward to the interior of the device, so as to prevent the purified water from re-entering the interior of the device, which will not only cause a waste of energy, but also cause the clean water to fall into the interior of the drain box 26, causing the clean water to be discharged from the device along the drain box 26, resulting in a waste of water resources.

[0041] Specifically, the outer wall of the filter housing 1 close to the top of the water outlet is fixedly connected with a mounting plate 11 , and the inner wall of the mounting plate 11 close to the driving chain 16 is slidably connected to the driving chain 16 .

[0042] In this embodiment, since the rotating filter usually needs to be partially placed underground, the device can be fixed on the ground by setting the mounting plate 11. The equipment on the mounting plate 11 can be used to control and clean the equipment, while the equipment under the mounting plate 11 will be placed in the sewage for filtering operations.

[0043] Specifically, a side of the limiting plate 19 close to the filter housing 1 is fixedly connected to a limiting baffle, and an outer wall of the limiting baffle is slidably connected to an inner wall of the limiting chain 17 .

[0044] In this embodiment, since the limit chain 17 itself is used to position or limit the filter body 21, the limit chain 17 itself will be transmitted along with the filter body 21. If the position of the limit chain 17 falls off, the equipment may be damaged. The limit plate 19 can limit the limit chain 17 through the limit baffle while limiting the rotating shaft 14. Since a water inlet is provided on the surface of the limit plate 19, the strength of the limit plate 19 itself will become lower. The edge of the limit plate 19 can be strengthened by setting the limit baffle, so that the limit plate 19 can withstand greater stress.

[0045] When using, First, after the sewage enters the device from the water inlet, the drive motor 12 is started. The drive motor 12 will transmit power to the rotating shaft 14 near the top of the device through the transmission belt 13, and the sprocket 15 will rotate through the rotation of the rotating shaft 14. At this time, the engagement of the sprocket 15 with the driving chain 16 will drive the driving chain 16 to transmit, and the rotating shaft 14 and the sprocket 15 near the bottom of the device will cooperate and limit with the driving chain 16. When the driving chain 16 is transmitted, it will drive the filter body 21 to move synchronously. At this time, the sewage can be filtered through the filter holes on the filter body 21; in order to prevent the problem of clogging of the filter body 21 due to excessive impurities, a collecting block 28 is provided on the filter body 21 to remove impurities in the water. When the collecting block 28 is at the bottom of the filter body 21, the impurities that have settled to the bottom can be removed to prevent the bottom impurities from entering the filter holes of the filter body 21 and causing blockage.

[0046] At the same time, multiple collecting blocks 28 are arranged around the filter body 21 and the collecting blocks 28 are opened upward on one side of the filter body 21 and opened downward on the other side. During operation, the collecting blocks 28 with the opening upward will bring out part of the water. After the water is brought out, the internal water will fill the gap and flow toward the filter body 21. At the same time, impurities floating in the center of the water surface can flow to the position of the collecting block 28, thereby achieving the effect of removing impurities in the center of the water surface to prevent the continuous accumulation of internal impurities. Impurities suspended in the water can also be removed by this method; at the same time, the collecting blocks 28 with the opening downward will impact the water surface when entering the water surface, and the water inside the collecting blocks 28 will be impacted and enter the interior of the collecting blocks 28, and at the same time, a reaction force will be generated on the collecting blocks 28 and the filter body 21, and the blockage of the filter holes can be cleared by utilizing the reaction force of the water.

[0047] Secondly, when discharging impurities inside the collecting block 28, the setting of the pressing block 22 can move along the inner wall of the filter body 21 when it contacts the top of the filter housing 1, and because the collecting block 28 is hinged to the filter body 21, only the inclined portion of the collecting block 28 can squeeze the collecting block 28 inward, thereby increasing the angle of the collecting block 28 near the top. After the angle is increased, the internal impurities can slide along the inner wall of the collecting block 28, and the internal impurities can be concentrated by setting a collecting box; when the pressing block 22 is operating normally, the impurities will be retained inside the collecting block 28, and when the pressing block 22 and the collecting block 28 reach the top of the filter housing 1, the pressing block 22 and the collecting block 28 will be pressed down, and the impurities will not be discharged until the collecting block is pressed down to a certain angle, thereby preventing the impurities from falling into the water repeatedly, resulting in multiple operations required to collect the impurities.

[0048] Then, when it is necessary to collect impurities, the sewage box 26 needs to be placed in the device, and the shaking block is repeatedly in contact with the sewage box 26 when the rotating shaft 14 rotates. Since the shaking block is only provided at one end of the rotating shaft 14, only one end of the sewage box 26 will be repeatedly lifted up by the shaking block. The sewage box 26 is repeatedly lifted up by the shaking block to shake, and the impurities inside the sewage box 26 are spread out so that it can accommodate more impurities. At the same time, by shaking only one side of the sewage box 26, the impurities can be moved to the other side of the sewage box 26 through shaking and discharged through the sewage outlet. In the process of filtering water by the collecting block 28 and the filter body 21, some water will adhere to the surface of the collecting block 28 and impurities. When the collecting block 28 pours out impurities into the drain box 26, some water will also be poured out. The water on the surface of the drain box 26 can be repeatedly swung back and forth by vibration to remove impurities such as mud and sand attached to the surface of the drain box 26.

[0049] Finally, when the impurities are collected, the collecting block 28 moves to the lower position and loses the squeezing of the filter housing 1, and the pressing block 22 is reset through the reset spring 23 to prepare for the next filtering operation.
