Description

Technical Field

[0001] The utility model relates to the technical field of sewage filtration, in particular to a high-efficiency filter for water supply and drainage pipelines. Background Art

[0002] Drainage pipes refer to the system composed of pipes and their ancillary facilities that collect and discharge sewage, wastewater and rainwater. They include trunk pipes, branch pipes and pipes leading to treatment plants. No matter they are built on the streets or anywhere else, as long as they are used for drainage, they should be counted as drainage pipes.

[0003] A Chinese patent discloses a water supply and drainage pipe filter with a publication number of CN219481822U. The patent technology has a push rod and a third spring and other structures. When disassembly is required, the push rod is directly stepped on, and the bottom of the push rod drives the limit rod to move to the right, so that the block loses the limit. Due to the action of the third spring, the entire pipe body is ejected to the outside, so that the surface of the coarse filter is taken out for cleaning, and then the sliding sleeve is pushed down again after the cleaning is completed, so as to clean the fine filter at the bottom. The structure is simple and easy to clean. However, the above device filters sewage through multiple layers of filter nets, but two filter nets need to be taken out for cleaning. Since the filter net is used for water supply and drainage filtration, the surface area of ​​the filter net used is generally large, so it is inconvenient to take out and install the filter net, and because the cleaning time and installation time of the filter net are long, the device is out of service for too long. Therefore, the inventor provides a water supply and drainage pipe high-efficiency filter to solve the problems raised in the above background technology. Utility Model Content

[0013] The high-efficiency filter for water supply and drainage pipes has two rotating threaded rods that drive two moving blocks to move. When the upper moving block moves, it drives the hard-bristle brush and the shovel plate to move to the left. The shovel plate first contacts the top surface of the coarse filter to shovel away the silt on the top surface of the shovel plate, and then the hard-bristle brush brushes away the silt remaining on the surface of the coarse filter, and finally discharges the silt through the upper discharge slot.

[0014] In addition, for the high-efficiency filter of the water supply and drainage pipe, when the threaded rod rotates to drive the moving block to move to the left, the two filter screens will be cleaned, and at the same time, the moving block gradually approaches the fitting plate until the top support block contacts the left side of the fitting plate and pushes the fitting plate to the left, thereby the driving force causes the fitting plate and the flip rod to flip outward, and at the same time the volute spring is deformed. When the impurities are discharged, the threaded rod reverses and drives the moving block to move to the right. The reverse force after the deformation of the volute spring drives the fitting plate and the flip rod to flip inward, so that the fitting plate is tightly attached to the top support block until the fitting plate is attached to the surface of the treatment box and the plug-in frame is inserted into the discharge groove.

DETAILED DESCRIPTION

[0022] like Figure 1 , 2 As shown, a high-efficiency filter for water supply and drainage pipes includes a treatment box 10, a connecting pipe 11 is fixedly connected to the top of the treatment box 10, and a discharge pipe 12 is fixedly connected to the right side of the bottom of the treatment box 10; when in use, the connecting pipe 11 is connected to the water supply and drainage pipe, and the discharge pipe 12 is connected to the inlet pipe of the water storage tank.

[0023] The inside of the treatment box 10 is fixedly connected with a coarse filter 13 and a fine filter 14 from top to bottom; the sewage entering the treatment box 10 from the connecting pipe 11 will be filtered by the coarse filter 13 and the fine filter 14 in turn, and the filtered water source will be discharged through the discharge pipe 12, thereby achieving the effect of sewage filtering. By setting the coarse filter 13 and the fine filter 14, the effect of sewage filtering can be achieved step by step. The coarse filter 13 is mainly used to filter sand and stones in the sewage, and the fine filter 14 is mainly used to filter fine impurities in the sewage, and the effect of efficient filtering is achieved by filtering step by step.

[0024] While the filter is filtering sewage, sand or impurities will accumulate on the surface of the filter. If the filter is not cleaned, the filtering effect of the filter will be affected. If the filter is cleaned by disassembling it, it will be too troublesome and time-consuming, so the filter needs to be cleaned.

[0025] refer to Figure 2 , 3 4. Storage grooves 20 are respectively provided on the upper and lower sides of the processing box 10, and the bottom edges of the two storage grooves 20 are respectively fitted with the top edges of the corresponding coarse filter 13 or the corresponding fine filter 14; sliding grooves 21 are respectively provided on the upper and lower ends and the front and back sides of the processing box 10, and the right side of the sliding groove 21 is connected with the connection of the storage groove 20, and the left and right sides of the two sliding grooves 21 on the rear side are rotatably connected, and the surface of the threaded rod 23 is threadedly connected with a moving block 25 for cleaning the filter.

[0026] Specifically, guide rods 24 are fixedly connected to the left and right sides of the storage tank 20 at the front side, and the moving block 25 is slidably connected to the surface of the guide rods 24, so as to achieve the effect of guiding the moving block 25 when moving. A hard brush 26 is fixedly connected to the bottom of the moving block 25 at the upper side, and a shovel plate 27 is fixedly connected to the left side of the moving block 25 at the upper side; a soft brush 28 is fixedly connected to the bottom of the moving block 25 at the lower side; a pair of discharge slots 22 are opened on the left side of the processing box 10.

[0027] When in use, the two rotating threaded rods 23 rotate to drive the two moving blocks 25 to move. When the upper moving block 25 moves, it drives the bristle brush 26 and the shovel plate 27 to move leftward. The shovel plate 27 first contacts the top surface of the coarse filter 13 to shovel away the mud and sand on the top surface of the shovel plate 27, and then the bristle brush 26 brushes away the mud and sand remaining on the surface of the coarse filter 13, and finally discharges the mud and sand through the upper discharge groove 22. When the lower moving block 25 moves, it drives the soft brush 28 to move leftward, drives the soft brush 28 to brush away the impurities on the surface of the fine filter 14 from left to right, and finally discharges them through the lower discharge groove 22. Thus, the surface of the two filter screens is cleaned. After cleaning, the two threaded rods 23 are reversed to drive the two moving blocks 25 to move rightward and return to the inside of the storage tank 20.

[0028] refer to Figure 1 , 5 The right rear end of the processing box 10 is fixedly connected with a turning plate 30, and the left end of the turning plate 30 is fixedly connected with a motor 31. The output end of the motor 31 is fixedly connected to the upper threaded rod 23, and the output end of the motor 31 is fixedly connected with a synchronous pulley 32; the right side of the lower threaded rod 23 extends outward, and the right side of the lower threaded rod 23 is fixedly connected with the same synchronous pulley 32, and the outer sides of the two synchronous pulleys 32 are meshed with a transmission belt 33. When in use, the motor 31 is started by an external power supply, and the output end of the motor 31 drives the upper threaded rod 23 to rotate, and the cooperation of the synchronous pulley 32 and the transmission belt 33 drives the lower threaded rod 23 to rotate in the same direction.

[0029] The discharge groove 22 is used to discharge sand and impurities cleaned by the brush. If the discharge groove 22 is not closed, it may cause the sewage to contact the surface of the filter screen during sewage treatment, causing the sewage to splash and be discharged through the discharge groove 22. Therefore, a closing mechanism is proposed.

[0030] refer to Figure 4 , 6 The closing mechanism includes a pair of connection frames 40, which are fixedly connected to the surface of the processing box 10. The front and rear sides of the connection frame 40 are rotatably connected to a rotatable flip rod 41. A flip block 42 is fixedly connected to the flip rod 41. A bonding plate 43 is fixedly connected to the bottom of the flip block 42. A plug-in frame 44 is provided on the right side of the bonding plate 43. The outer surface of the plug-in frame 44 is adapted to the cross section of the discharge slot 22. When the bonding plate 43 is bonded to the surface of the processing box 10, the plug-in frame 44 is plugged into the inside of the discharge slot 22, thereby achieving the effect of closing the discharge slot 22. When the filter screen is cleaned, the flip rod 41 flips outward to drive the bonding plate 43 to flip in the same direction, and drives the plug-in frame 44 to detach from the inside of the discharge slot 22, thereby achieving the effect of exposing the discharge slot 22, so that impurities can be discharged through the discharge slot 22.

[0031] Specifically, a fixing ring 45 is provided on the front and rear sides of the flip rod 41, the outer side of the fixing ring 45 is fixedly connected to the surface of the connecting frame 40, and a spiral spring 46 is provided inside the fixing ring 45, the outer end of the spiral spring 46 is fixedly connected to the fixing ring 45, and the inner end of the spiral spring 46 is fixedly connected to the surface of the flip rod 41; a top support block 47 is fixedly connected to the left side of the moving block 25.

[0032] When the threaded rod 23 rotates and drives the moving block 25 to move to the left, the two filter screens will be cleaned. At the same time, the moving block 25 gradually approaches the bonding plate 43 until the top support block 47 contacts the left side of the bonding plate 43 and pushes the bonding plate 43 to the left, thereby the driving force causes the bonding plate 43 and the flip rod 41 to flip outward, and at the same time the spiral spring 46 is deformed. When the impurities are discharged, the threaded rod 23 reverses and drives the moving block 25 to move to the right. The reverse force of the deformed spiral spring 46 drives the bonding plate 43 and the flip rod 41 to flip inward, so that the bonding plate 43 is tightly attached to the top support block 47 until the bonding plate 43 is attached to the surface of the processing box 10 and the plug-in frame 44 is inserted into the discharge groove 22.

[0033] Preferably, a pair of collecting boxes 50 are installed on the left side of the processing box 10, and the two collecting boxes 50 are respectively located at the outer bottom of the two discharge grooves 22, so that impurities discharged from the discharge grooves 22 will fall into the collecting box 50, thereby achieving the effect of impurity collection.

[0034] The working principle of the utility model is as follows: the motor 31 is started by an external power supply, the output end of the motor 31 drives the upper threaded rod 23 to rotate, and the cooperation of the synchronous pulley 32 and the transmission belt 33 drives the lower threaded rod 23 to rotate in the same direction. The two rotating threaded rods 23 rotate and drive the two moving blocks 25 to move. When the upper moving block 25 moves, it drives the bristle brush 26 and the shovel plate 27 to move leftward. The shovel plate 27 first contacts the top surface of the coarse filter 13, shovels away the mud and sand on the top surface of the shovel plate 27, and then the bristle brush 26 brushes away the mud and sand remaining on the surface of the coarse filter 13, and finally discharges the mud and sand through the upper discharge groove 22. When the lower moving block 25 moves, it drives the soft brush 28 to move leftward, drives the soft brush 28 to brush away the impurities on the surface of the fine filter 14 from left to right, and finally discharges through the lower discharge groove 22. Thereby, the effect of cleaning the surfaces of the two filter screens is achieved. After cleaning, the two threaded rods 23 are reversed to drive the two moving blocks 25 to move rightward and return to the inside of the storage tank 20. Thereby achieving the effect of cleaning the filter surface.
