Abstract
Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, and more specifically, to a wastewater treatment device that facilitates the cleaning of filter residue. Background Technology
[0002] In industrial production and other fields, wastewater treatment is a key link in ensuring the recycling of water resources and reducing environmental pollution. With increasingly stringent environmental protection requirements and the intensification of water shortage problems, the demand for efficient and convenient wastewater treatment equipment is becoming more and more urgent. Among them, filtration, as the core process in wastewater treatment, plays a major role in intercepting suspended particulate matter, impurities, residues and other solid pollutants in wastewater to achieve preliminary purification of water quality and lay the foundation for subsequent biochemical treatment, disinfection and other processes.
[0003] Most existing filtration devices use fixed filter plates or screens, causing filter residue to continuously adhere to the surface of the filter media. Over time, this residue accumulates, forming a filter cake that not only clogs the filter channels, increasing wastewater flow resistance and significantly reducing filtration speed, but also can cause "penetration" due to excessively thick filter cake layers. This allows unfiltered wastewater to directly enter subsequent processes, severely impacting effluent quality. Traditional devices typically require manual disassembly of equipment components (such as opening the housing and removing the filter plates) after shutdown, followed by cleaning the filter residue through scraping, high-pressure water washing, or replacing the filter media. This process requires professional operators and is cumbersome, with each cleaning session often taking tens of minutes or even hours, significantly reducing the overall operating time and processing capacity of the wastewater treatment system.
[0004] To address the aforementioned issues, a wastewater treatment device that facilitates the cleaning of filter residue is proposed. Utility Model Content
[0005] To solve the above-mentioned technical problems, a wastewater treatment device that facilitates the cleaning of filter residue is provided.
[0006] To achieve the above objectives, the present invention can be implemented using the following technical solutions: This utility model provides a wastewater treatment device that facilitates the cleaning of filter residue, comprising: a treatment tank, a positioning rod fixedly installed inside the treatment tank, a lead screw installed on the side of the treatment tank away from the positioning rod, mounting blocks installed on the outer periphery of both the lead screw and the positioning rod, one mounting block being threadedly connected to the lead screw, and the other mounting block being slidably connected to the positioning rod, a scraper being detachably installed on the bottom of the mounting blocks, a triangular strip being installed above both the lead screw and the positioning rod, and a drive motor fixedly installed on the outer wall of the treatment tank, the output end of the drive motor being fixedly connected to one end of the lead screw.
[0007] Preferably, the treatment box has drain ports on both sides inside, and grooves are provided on both sides inside the treatment box and on the side wall with the smaller area. A filter plate is slidably connected inside the groove. Limiting blocks are symmetrically installed on one outer wall of the treatment box. The limiting blocks are rotatably connected to the outer wall of the treatment box. The bottom of the scraper slides against the surface of the filter plate. Collection boxes are symmetrically installed on both outer sides of the treatment box. The drain ports extend into the interior of the collection boxes. After the limiting blocks are rotated, they abut against one side wall of the filter plate.
[0008] Preferably, the top of the processing box is rotatably connected to a cover plate, a feed pipe is fixedly installed in the middle of the top side of the cover plate, and viewing windows are symmetrically installed on both sides of the cover plate.
[0009] Preferably, the bottom of the processing box is equipped with casters on all four sides.
[0010] Preferably, the bottom of the processing box has a certain slope, and a discharge pipe is fixedly installed on one side of the processing box.
[0011] As described above, the features and advantages of this wastewater treatment device that facilitates filter cake cleaning are: An automated filter cake cleaning system is constructed through a linkage structure of "drive motor - lead screw - scraper". After the drive motor starts, it drives the lead screw to rotate. The mounting block connected to the lead screw moves along the lead screw axis, while the mounting block on the other side slides along the positioning rod, ensuring that the scraper always maintains a stable posture and adheres to the surface of the filter plate. During the movement of the scraper, the filter cake accumulated on the filter plate can be quickly scraped off and pushed to the drain ports on both sides of the treatment box. Finally, the filter cake falls into the collection box automatically through the drain ports. The entire cleaning process does not require manual intervention and can be completed without stopping the equipment, avoiding the long downtime caused by manual cleaning in traditional devices, and significantly improving the overall processing capacity.
[0012] The sloped design at the bottom of the treatment tank allows the filtered water to naturally flow towards the discharge pipe, preventing stagnant water from forming at the bottom and reducing the possibility of bacterial growth. Simultaneously, the sloped structure accelerates the water discharge rate, lowers the water pressure inside the treatment tank, and further reduces the risk of filter cake "penetrating" the filter plates.

Detailed Implementation
[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0016] See Figures 1-5 As shown, this is an embodiment of the present invention. A wastewater treatment device that facilitates the cleaning of filter residue will be described in detail below: A wastewater treatment device that facilitates the cleaning of filter residue, such as Figures 1-5As shown, the system includes: a processing box 1, inside which a positioning rod 12 is fixedly installed; a lead screw 14 is installed on the side of the processing box 1 away from the positioning rod 12; mounting blocks 15 are installed on the outer periphery of both the lead screw 14 and the positioning rod 12; one mounting block 15 is threadedly connected to the lead screw 14, and the other mounting block 15 is slidably connected to the positioning rod 12; a scraper 11 is detachably installed on the bottom of the mounting blocks 15 by bolts; triangular strips are installed above both the lead screw 14 and the positioning rod 12; a drive motor 4 is fixedly installed on the outer wall of the processing box 1; the output end of the drive motor 4 is fixedly connected to one end of the lead screw 14; after the drive motor 4 starts, its output end drives the lead screw 14 inside the processing box 1 to rotate; and the mounting blocks 15 on the outer periphery of the lead screw 14 are threadedly connected to the lead screw 14. The screw 14 is threaded, and the mounting block 15 on the other side is slidably connected to the positioning rod 12 (the positioning rod 12 is fixed to the inner wall of the treatment box 1 and serves as a guide). The rotational movement of the screw 14 is converted into the synchronous axial movement of the two mounting blocks 15. The scraper 11, which is detachably installed at the bottom of the mounting block 15 by bolts, moves with the mounting block 15, and the bottom of the scraper 11 is always in close contact with the surface of the filter plate 5. During the movement, the filter residue on the filter plate 5 is pushed to both sides of the treatment box 1. The triangular strip above the screw 14 and the positioning rod 12 can prevent the filter residue from adhering to the screw 14 and the positioning rod 12 and affecting the movement of the mounting block 15. When the scraper 11 pushes the filter residue to the drain ports 16 on both sides inside the treatment box 1, the filter residue falls into the collection box 2 symmetrically installed on the outside of the treatment box 1 under the pushing force of the scraper 11. The collection box 2 is independently connected to the treatment box 1. After the collection box 2 is full of filter residue, it can be opened directly for dumping.
[0017] Furthermore, both sides of the treatment tank 1 are provided with drain outlets 16. Both sides of the treatment tank 1 and the side wall with the smaller area are provided with sliding grooves 13. Filter plates 5 are slidably connected inside the sliding grooves 13. Limiting blocks 6 are symmetrically installed on one outer wall of the treatment tank 1. The limiting blocks 6 are rotatably connected to the outer wall of the treatment tank 1. The bottom of the scraper 11 slides against the surface of the filter plate 5. Collection tanks 2 are symmetrically installed on both outer sides of the treatment tank 1. The drain outlets 16 extend into the interior of the collection tanks 2. After the limiting blocks 6 rotate, they abut against one side wall of the filter plate 5. The filter plate 5 is slidably connected to the treatment tank 1 through the sliding grooves 13. Both sides are rotated downwards by the limiting blocks 6 under the action of gravity and abut against the side wall of the filter plate 5, ensuring that the filter plate 5 does not shift under the impact of sewage.
[0018] Furthermore, such as Figures 1-5 As shown, a cover plate 7 is rotatably connected to the top of the processing box 1. A feed pipe 9 is fixedly installed in the middle of the top side of the cover plate 7. Viewing windows 8 are symmetrically installed on both sides of the cover plate 7. Universal wheels 3 are installed around the bottom of the processing box 1. The bottom of the processing box 1 has a certain slope. A discharge pipe 10 is fixedly installed on one side of the processing box 1.
[0019] Through the above scheme, the wastewater to be treated is injected into the treatment tank 1 through the feed pipe 9 on the top side of the cover plate 7. The cover plate 7 can effectively isolate external dust and impurities from entering the treatment tank 1, preventing secondary pollution. The bottom of the treatment tank 1 is designed with a slope, and the clean water passing through the filter plate 5 naturally gathers to the lower position along the slope and is finally discharged through the discharge pipe 10 on one side of the treatment tank 1. The slope structure accelerates the flow of clean water and avoids the clean water from accumulating at the bottom of the treatment tank 1, ensuring stable effluent quality. During this process, the operator can observe the wastewater level in the treatment tank 1 and the filter residue accumulation on the filter plate 5 in real time through the viewing windows 8 on both sides of the cover plate 7, so as to determine whether the cleaning program needs to be started. The casters 3 around the bottom of the treatment tank 1 can drive the device to move flexibly, which is suitable for scenarios such as construction sites and agricultural irrigation areas that require multi-point wastewater treatment. After moving to the target position, the braking structure of the casters 3 is locked to ensure that the device remains stable during operation and avoids displacement caused by wastewater flow or motor vibration.
[0020] Specifically, the wastewater to be treated is injected into the treatment tank 1 through the feed pipe 9 on the top side of the cover plate 7. The cover plate 7 can effectively isolate external dust and impurities from entering the treatment tank 1, preventing secondary pollution. After the wastewater enters the treatment tank 1, it falls naturally onto the surface of the filter plate 5. The filter plate 5 is slidably connected to the treatment tank 1 through the slide groove 13, and the two sides are rotated downwards by the limiting blocks 6 under the action of gravity to abut against the side wall of the filter plate 5, ensuring that the filter plate 5 does not shift under the impact of wastewater. The clean water in the wastewater falls to the bottom of the treatment tank 1 through the filter holes, while suspended particulate matter, residue and other solid pollutants are trapped on the upper surface of the filter plate 5, completing solid-liquid separation. The bottom of the treatment tank 1 is designed with a slope, allowing the filter plate to pass through. The clean water from tank 5 naturally flows downhill and eventually discharges through the discharge pipe 10 on one side of treatment tank 1. The slope structure accelerates the flow of clean water, preventing it from accumulating at the bottom of treatment tank 1 and ensuring stable effluent quality. During this process, operators can observe the sewage level and filter cake accumulation on the filter plate 5 in real time through the viewing windows 8 on both sides of the cover plate 7. This helps determine whether a cleaning process needs to be initiated. When a thick layer of filter cake is observed on the surface of the filter plate 5 through the viewing window 8, or when the flow rate of the discharge pipe 10 decreases significantly, the drive motor 4 on the outer wall of treatment tank 1 is started to enter the filter cake cleaning stage. This stage does not require stopping the machine; only the feed pipe 9 needs to be lowered appropriately. To control the wastewater inflow and prevent overflow during cleaning, the drive motor 4 starts, and its output drives the lead screw 14 inside the treatment tank 1 to rotate. Since the mounting block 15 on the outer periphery of the lead screw 14 is threadedly connected to the lead screw 14, and the other mounting block 15 is slidably connected to the positioning rod 12 (the positioning rod 12 is fixed to the inner wall of the treatment tank 1 and serves as a guide), the rotational motion of the lead screw 14 is converted into synchronous axial movement of the two mounting blocks 15. The scraper 11, which is detachably mounted on the bottom of the mounting block 15 via bolts, moves with the mounting block 15, and the bottom of the scraper 11 always remains in close contact with the surface of the filter plate 5. During the movement, it pushes the filter residue on the filter plate 5 to both sides of the treatment tank 1. When the scraper 11 pushes the filter residue to the drain ports 16 on both sides inside the treatment box 1, the filter residue falls into the collection box 2 symmetrically installed on the outside of the treatment box 1 under the pushing force of the scraper 11. The collection box 2 is independently connected to the treatment box 1. After the collection box 2 is full of filter residue, it can be opened for dumping without disassembling the internal structure of the treatment box 1, making the operation convenient. After the filter residue is cleaned, the drive motor 4 is reversed, and the lead screw 14 drives the mounting block 15 and the scraper 11 back to the initial position (the side of the treatment box 1 near the positioning rod 12). Then the normal sewage inlet flow of the feed pipe 9 is restored, and the device re-enters the sewage filtration stage, realizing the cycle of "filtration-cleaning-re-filtration". The casters 3 around the bottom of the treatment box 1 can move the device flexibly, which is suitable for scenarios such as construction sites and agricultural irrigation areas that require multi-point sewage treatment. After moving to the target position, the braking structure of the casters 3 is locked to ensure that the device remains stable during operation and avoids displacement due to sewage flow or motor vibration.
