Description

Technical Field

[0001] This utility model relates to the field of wastewater treatment equipment technology, and in particular to a device for treating and reusing lightly polluted wastewater. Background Technology

[0002] Wastewater treatment involves using physical, chemical, and biological methods to render polluted water harmless, removing impurities and purifying it to make it clear, thus facilitating subsequent reuse and conserving water resources.

[0003] Existing wastewater treatment and reuse devices typically guide wastewater directly into the device and treat it using chemical reagents for sedimentation, without any pretreatment of the original wastewater. Some only add a filter screen, but it is prone to clogging and difficult to clean over time, resulting in a heavy workload on the device, increased chemical reagent input, increased costs, prolonged settling time, low water purification efficiency, and poor purification effect.

[0004] Therefore, addressing the issues of existing wastewater treatment and reuse devices that do not perform any pretreatment on the original wastewater, some of which only add a filter screen, which easily becomes clogged and difficult to clean over time, resulting in a heavy workload, increased chemical input, higher costs, prolonged settling time, low water purification efficiency, and poor purification effect, a lightly polluted wastewater treatment and reuse device can be designed. This device connects a pretreatment tank to the pipe transporting the wastewater source and the wastewater purification assembly. During wastewater transport, the filter screen performs preliminary filtration, blocking larger impurities. Simultaneously, at controlled intervals, the brushes on the fixed plate clean and unclog the mesh of the filter screen. A synchronously moving L-shaped collecting plate collects the protruding debris, and a moving pusher pushes it into a collection box for unified sorting, completing the self-cleaning and waste removal process. Utility Model Content

[0005] To overcome the problems of existing wastewater treatment and reuse devices that do not perform any pretreatment on the original wastewater, some only add a layer of filter screen, but which is easy to clog and difficult to clean over time, resulting in a heavy workload in the device, increased chemical reagent input, increased input costs, prolonged settling time, low water purification efficiency, and poor purification effect.

[0006] The technical solution of this utility model is as follows: a light wastewater treatment and reuse device, including a pretreatment box; it also includes a filter screen, a pusher plate, an L-shaped receiving plate and brush bristles. A through groove is opened in the middle of the upper end of the pretreatment box. A collection box is set on the right side of the pretreatment box. A filter screen is fixedly connected to the middle of the inner side of the pretreatment box. A rectangular frame with a front groove is fixedly connected to the filter screen and the upper end of the pretreatment box. A rectangular frame is fixedly connected to the middle of the upper end of the rectangular frame. A threaded rod is rotatably connected to the inner side of the rectangular frame. A pusher plate is threadedly connected to the outer side of the threaded rod. The same threaded rod is symmetrically rotatably connected to the front and rear sides of the bottom of the rectangular frame and the inner bottom wall of the pretreatment box. A lifting block is threadedly connected to the outer side of the front threaded rod. An L-shaped receiving plate is fixedly connected to the rear end of the lifting block. A lifting cylinder is threadedly connected to the outer side of the rear threaded rod. A connecting rod is fixedly connected to the lower front end of the lifting cylinder. A fixing plate is fixedly connected to the front end of the connecting rod. Bristles are fixedly connected to the front surface of the fixing plate.

[0007] Preferably, the L-shaped receiving plate is first placed at the bottom inner side of the pretreatment box. At this time, the fixing plate and the brush bristles are also simultaneously located at the bottom inner side of the pretreatment box. The two threaded rods can be set to rotate together at regular intervals. During this time, the rear threaded rod drives the lifting cylinder to rise, which in turn drives the fixing plate to rise through the connecting rod, and the brush bristles...

[0008] The garbage particles clogging the filter screen are pushed out. At the same time, the threaded rod on the front side drives the lifting block to rise, and the lifting block also drives the L-shaped receiving plate to rise synchronously. The garbage that is pushed down is caught and carried upward to the through slot on the pretreatment box. The threaded rod is controlled to rotate, and the pusher plate pushes the garbage collected in the L-shaped receiving plate to the right and drops it into the collection box from the right side.

[0009] Preferably, the inner side of the rectangular frame 2 is rotatably connected to five parallel gears via a rotating shaft, with adjacent gears meshing with each other. The two outermost gears are fixedly connected to the corresponding two threaded rods 2 via rotating shafts.

[0010] Preferably, a motor is fixedly installed on the upper end of the rectangular frame 2, and the output shaft of the motor is fixedly connected to the shaft of the gear located in the middle.

[0011] Preferably, a second motor is fixedly installed on the left end of the rectangular frame one, and the output shaft of the second motor is fixedly connected to the threaded rod one.

[0012] Preferably, the lower rear side of the L-shaped receiving plate is fitted to the surface of the filter screen, and the front surface of the L-shaped receiving plate has multiple filter holes arranged in an array.

[0013] Preferably, an inclined guide plate is fixedly connected to the upper right side of the pretreatment box, and the inclined guide plate is positioned above the collection box.

[0014] Preferably, four brakeable casters are evenly fixedly installed on the bottom of the collection box, and a handle is fixedly connected to the right end of the collection box.

[0015] The beneficial effects of this utility model are:

[0016] The device is equipped with a pretreatment box, which can be connected between the pipe conveying the sewage source and the sewage purification assembly. During the sewage transportation process, the sewage undergoes preliminary filtration through the filter screen, blocking larger impurities. At regular intervals, two threaded rods are controlled to rotate synchronously. As the fixed plate moves upward, brushes clean and push down debris clogging the filter screen mesh, which is then collected by a synchronously moving L-shaped receiving plate. At the top, a moving pusher plate pushes the collected debris into the collection box for unified sorting. This pretreatment filters out larger impurities, automatically cleans and unclogs the filter, and removes debris to prevent blockages from affecting filtration efficiency. This reduces the workload of subsequent sewage purification, lightens the workload, reduces the amount of chemical reagents required, saves costs, shortens settling time, and improves sewage purification efficiency and effect.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-4 This utility model provides an embodiment: a light wastewater treatment and reuse device, including a pretreatment tank 1; it also includes a filter screen 4, a pusher plate 8, an L-shaped receiving plate 11, and brush bristles 15. A through groove 2 is provided in the middle of the upper end of the pretreatment tank 1. A collection box 3 is provided on the right side of the pretreatment tank 1. The filter screen 4 is fixedly connected to the middle of the inner side of the pretreatment tank 1. A rectangular frame with a front-end slot is fixedly connected to the filter screen 4 and the upper end of the pretreatment tank 1. The upper end of the rectangular frame 5... A rectangular frame 6 is fixedly connected to the pretreatment box 1. A threaded rod 7 is rotatably connected to the inner side of the rectangular frame 6. A pusher plate 8 is threadedly connected to the outer side of the threaded rod 7. The bottom front and rear sides of the rectangular frame 6 are symmetrically rotatably connected to the inner bottom wall of the pretreatment box 1 by identical threaded rods 9. A lifting block 10 is threadedly connected to the outer side of the front threaded rod 9. An L-shaped receiving plate 11 is fixedly connected to the rear end of the lifting block 10. A lifting cylinder 12 is threadedly connected to the outer side of the rear threaded rod 9. A connecting rod 13 is fixedly connected to the lower front end of the device. A fixing plate 14 is fixedly connected to the front end of the connecting rod 13. Brush bristles 15 are fixedly connected to the front surface of the fixing plate 14. First, the L-shaped receiving plate 11 is placed at the bottom inside the pretreatment box 1. At this time, the fixing plate 14 and brush bristles 15 are also located at the bottom inside the pretreatment box 1. The two threaded rods 9 can be set to rotate together at regular intervals. At this time, the threaded rod 9 on the rear side drives the lifting cylinder 12 to rise, and drives the fixing plate 14 to rise through the connecting rod 13. The brush bristles 15 push out the garbage particles that are blocking the mesh of the filter plate 4. At the same time, the threaded rod 9 on the front side drives the lifting block 10 to rise. The lifting block 10 also drives the L-shaped receiving plate 11 to rise synchronously, receiving the garbage that falls down and carrying it upward to the through groove 2 on the pretreatment box 1. The threaded rod 7 is controlled to rotate, and the pushing plate 8 pushes the garbage collected in the L-shaped receiving plate 11 to the right and drops it into the collection box 3 for collection.

[0024] Please see Figures 2-4In this embodiment, five parallel gears 16 are rotatably connected to the inner side of the rectangular frame 2 6 via a rotating shaft, and adjacent gears 16 are meshed together. The two outermost gears 16 are fixedly connected to the corresponding two threaded rods 2 9 via rotating shafts. Through the transmission of the gears 16, the two threaded rods 2 9 can be rotated simultaneously. A motor 17 is fixedly installed at the upper end of the rectangular frame 2 6. The output shaft of the motor 17 is fixedly connected to the rotating shaft of the gear 16 located in the middle. By starting the motor 17, the gear 16 in the middle is rotated, and the meshing transmission of each gear 16 drives the two threaded rods 2 9 to rotate. A motor 2 18 is fixedly installed at the left end of the rectangular frame 1 5, and the output shaft of the motor 2 18 is fixedly connected to the threaded rod 1 7. By starting the motor 2 18, the threaded rod 1 7 is rotated, thereby controlling the pusher plate 8 to push the garbage collected in the L-shaped receiving plate 11 to the right.

[0025] Please see Figures 1-2 In this embodiment, the lower rear side of the L-shaped receiving plate 11 is fitted to the surface of the filter screen plate 4. The front surface of the L-shaped receiving plate 11 has multiple filter holes 19 arranged in an array. The L-shaped receiving plate 11 can collect the blockage debris that falls down. When it is raised above the water level, the water in the collected debris flows out from each filter hole 19. An inclined guide plate 20 is fixedly connected to the upper right side of the pretreatment box 1 and is positioned above the collection box 3. The inclined guide plate 20 is used to guide the stable discharge of the collected debris in the L-shaped receiving plate 11 and prevent it from falling onto the outer wall of the pretreatment box 1. Four brakeable universal wheels 21 are evenly fixedly installed at the bottom of the collection box 3. A handle 22 is fixedly connected to the right end of the collection box 3. When a certain amount of debris is collected in the collection box 3, the handle 22 can be held to push the device through the brakeable universal wheels 21 at the bottom of the collection box 3 to transfer the collected debris.

[0026] During operation, this device is connected between the pipe conveying the sewage source and the sewage purification assembly. First, the L-shaped receiving plate 11 is placed at the bottom inner side of the pretreatment box 1. At this time, the fixing plate 14 and brush 15 are also simultaneously located at the bottom inner side of the pretreatment box 1. A certain time interval is set to start the motor 17, which first drives the gear 16 on the middle side to rotate. Then, the meshing transmission of adjacent gears 16 drives the two threaded rods 9 to rotate. At this time, the threaded rod 9 on the rear side drives the lifting cylinder 12 to rise, which in turn drives the fixing plate 14 to rise through the connecting rod 13. The brush 15 pushes out the garbage particles clogging the mesh of the filter screen 4, and simultaneously… The threaded rod 29 on the front side drives the lifting block 10 to rise, and the lifting block 10 also drives the L-shaped receiving plate 11 to rise synchronously, to receive the garbage that falls down, and to carry it upward to the through groove 2 on the pretreatment box 1. The water that remains is discharged into the pretreatment box 1 through the filter hole 19. The motor 218 is started to control the threaded rod 7 to rotate. The pusher plate 8 pushes the garbage collected in the L-shaped receiving plate 11 to the right, and guides it from the right side by the inclined guide plate 20, so that it falls into the collection box 3 for collection. When the amount of collected garbage accumulates to a certain level, the handle 22 is held to push the device to move through the brakeable universal wheels 21 at the bottom of the collection box 3 to transfer the collected garbage.

[0027] Through the above steps, the device includes a pretreatment box 1, which can be connected between the pipe conveying the sewage source and the sewage purification assembly. During the sewage transport process, the sewage undergoes preliminary filtration through the filter screen 4, blocking larger impurities. Simultaneously, at controlled intervals, the brush bristles 15 on the surface of the fixed plate 14 clean and unclog the mesh of the filter screen 4. The L-shaped collecting plate 11, moving upwards synchronously, collects the protruding debris. Once at the top, the moving pusher plate 8 pushes the debris into the collection box 3 for unified sorting, thus completing the pretreatment filtration of the sewage, filtering out a batch of larger impurities. It can automatically clean and unclog, and transport the waste away to prevent blockages from affecting filtration efficiency. This reduces the workload of subsequent wastewater treatment, lightens the workload, reduces the amount of chemical reagents required, saves costs, shortens settling time, and improves wastewater purification efficiency and effectiveness. This addresses the problems of existing wastewater treatment and reuse devices that do not perform any pretreatment of the original wastewater. Some only add a filter screen, which is prone to blockage and difficult to clean over time. This results in a heavy workload for the device, increased chemical reagents required, increased costs, prolonged settling time, low water purification efficiency, and poor purification effect.
