Description

Technical Field

[0001] This utility model relates to the field of water treatment technology, and in particular to an energy-saving water treatment device. Background Technology

[0002] With the continuous development of science and technology, people are paying more and more attention to environmental protection. Among them, the problem of sewage discharge is the most common environmental phenomenon. Sewage needs to be filtered and purified before it can be directly discharged into the environment or recycled. The sewage treatment process is the process of purifying sewage to meet the water quality requirements for discharge into a certain water body or reuse.

[0003] Chinese Patent CN221831770U discloses an energy-saving water treatment device. The device is characterized by including a purification device containing a purification unit, a purification structure, and a filter screen. A limiting plate is connected to the filter screen, and an opening is located beside the limiting plate. A scraper is connected to the opening, with its lower end fitting against the inner side of the filter screen. This invention utilizes a motor within the purification device to rotate a rotating shaft, causing the filter screen to rotate. Finally, the fixed scraper completely removes solid impurities from the energy-saving water treatment device. This effectively prevents the scraped-out impurities from falling downwards through the gap as the auger rod moves upwards, which would eventually cause excessive accumulation of solid impurities on the filter screen, severely affecting the filtration effect.

[0004] However, the above-mentioned solutions have limited contact area between the scraper and the filter screen when treating wastewater. Some impurities will remain on the filter screen, which will gradually accumulate and cause the filter screen to become clogged, affecting the filtration efficiency. In addition, high viscosity or high concentration of suspended solids are easy to adhere to the filter screen, forming a dirt layer that is difficult to remove. Scraper cleaning cannot completely remove the dirt adhering to the filter screen. Therefore, an energy-saving water treatment device is proposed to solve the above-mentioned problems. Utility Model Content

[0005] To address the technical problem that during wastewater treatment, the limited contact area between the scraper and the filter screen leads to some impurities remaining on the filter screen, which gradually accumulates and causes clogging, and that high-viscosity or high-concentration suspended solids easily adhere to the filter screen, making it impossible for scraper cleaning to completely remove the dirt adhering to the filter screen, this application provides an energy-saving water treatment device.

[0006] This utility model proposes an energy-saving water treatment device, including a water tank, and a filter device is provided on the outer side of the water tank. The filter device includes a wedge-shaped filter screen tube, which filters sewage through its V-shaped slits.

[0007] The inner wall of the groove of the water tank is provided with a fixing device, which includes a fixing block and a fixing frame. The relative movement of the fixing block fixes the fixing frame.

[0008] Preferably, the filtration device further includes a tank cover, which is fixedly installed on the upper surface of the water tank by bolts, and a drain tee pipe with an electric three-way valve is fixedly connected to the bottom surface of the water tank.

[0009] With the above technical solution, the tank cover is fixed to the water tank with bolts, which facilitates disassembly while fixing it. The water tank is fixedly connected to the drain tee pipe that drives the electric tee pipe, which facilitates the control of the flow direction of the filtered water. An adsorption water purification device is installed in the water tank. Since the adsorption water purification device is a mature existing technology, this utility model does not describe it in detail. The staff can select a suitable adsorption water purification device according to actual needs, such as activated carbon adsorption, ion exchange resin, etc.

[0010] Preferably, the wedge-shaped filter tube is slidably inserted into the groove on the left side of the top of the water tank, and the outer surface of the left end of the wedge-shaped filter tube is threaded with an inlet tee pipe with an electric three-way valve, and the outer surface of the right end of the wedge-shaped filter tube is threaded with an outlet pipe with an electric valve. The wedge-shaped filter tube is made of stainless steel.

[0011] The above technical solution utilizes a wedge-shaped filter tube that slides into the water tank, securing it while facilitating removal. The wedge-shaped filter tube is also threaded into the inlet tee, ensuring easy disassembly. An electric tee valve allows for adjustment of water flow as needed. The wedge-shaped filter tube is also threaded into the outlet pipe, securing it while facilitating disassembly. Made of stainless steel, the wedge-shaped filter tube offers excellent corrosion resistance and mechanical strength, ensuring it is durable and easy to clean. The electric valve used in the filtration system can be the Hailin Energy-Saving HL-G2-3 / 4-S2, offering high cost-effectiveness and significant energy savings. The electric tee valve can be the ZLDF-320, featuring a built-in limit switch and manual valve opening function, facilitating debugging and energy-efficient operation.

[0012] Preferably, two silicone rings are fixedly bonded to the outer surface of the wedge-shaped filter tube. The left side of one silicone ring contacts the right end of the right end of the water pipe of the inlet tee, and the right side of the other silicone ring contacts the left end of the outlet pipe.

[0013] The above technical solution uses a wedge-shaped filter tube to be fixedly bonded to a silicone ring, which not only secures the filter but also facilitates replacement. One silicone ring contacts the right end of the water pipe at the right end of the inlet tee, and the other silicone ring contacts the left end of the outlet pipe to seal it and prevent water leakage.

[0014] Preferably, a differential pressure sensor is threadedly connected to the outer surface of the right end of the inlet tee pipe and the inner wall of the threaded groove of the outlet pipe. A protective cover is fixedly bonded to the outer surface of the right end of the inlet tee pipe and the outer surface of the outlet pipe with a waterproof adhesive, and the differential pressure sensor is located inside the protective cover.

[0015] The above technical solution involves connecting the positive pressure ports of two differential pressure sensors to the inlet tee and outlet pipes respectively via threads, allowing for easy fixation and disassembly. The differential pressure sensors detect the pressure difference across the wedge-shaped filter screen, determining whether cleaning is required. Honeywell 26PC series sensors are recommended, as they offer high precision and corrosion resistance, making them suitable for fluid pressure detection. Two protective covers are fixed to the inlet tee and outlet pipes with waterproof adhesive. The differential pressure sensors are located inside the protective covers, which provide protection. The covers are made of stainless steel, offering high strength and durability, withstanding mechanical impacts, and excellent corrosion resistance, making them suitable for water treatment environments.

[0016] Preferably, the fixing device further includes a slider, which is slidably sleeved on the round rod surface of the fixing frame, and the right frustum surface of the slider is slidably connected to the inner wall of the frustum groove of the fixing frame, and the fixing frame is fixedly installed on the outer surface of the wedge-shaped filter tube.

[0017] The above technical solution uses a slider that slides into a fixed frame, fixing it without affecting its movement. The slider consists of two frustums of different sizes, with the larger frustum being the same size as the frustum of the fixed frame and the two being symmetrically arranged. The smaller frustum on the slider slides into the frustum groove of the fixed frame, and the bottom surface of the larger frustum on the slider contacts the bottom surface of the frustum of the fixed frame, forming a double frustum structure. Due to its structural features, it is easy to fix the fixed block to the frustum of the fixed frame and then release it.

[0018] Preferably, the fixing block is slidably inserted into the groove on the left side of the top of the water tank, the arcuate groove of the fixing block is in contact with the round rod surface of the fixing frame, and a stainless steel spring is fixedly installed on the outer side of the fixing block. The stainless steel spring is fixedly installed in the groove on the left side of the top of the water tank.

[0019] The above technical solution uses a fixing block that slides into the water tank, fixing it without affecting its movement. The fixing block's arc groove contacts the round rod of the fixing frame, thus fixing the fixing frame. Stainless steel springs are used to fix the fixing block and the water tank respectively. After the fixing block moves, it returns to its original position to fix the fixing frame, thereby fixing the wedge-shaped filter tube that is fixedly installed with the fixing frame.

[0020] The beneficial effects of this utility model are as follows:

[0021] 1. By setting up a filtration device, sewage is filtered. The water tank is fixedly connected to the drain tee pipe that drives the electric tee valve, facilitating the control of the filtered water discharge direction. The wedge-shaped filter screen tube is threadedly connected to the inlet tee pipe. The electric tee valve can adjust the water flow direction as needed. The wedge-shaped filter screen tube is threadedly connected to the outlet pipe. One silicone ring contacts the right end of the inlet tee pipe, and the other silicone ring contacts the left end of the outlet pipe for sealing. A differential pressure sensor can be used to detect the pressure difference across the wedge-shaped filter screen tube, thereby determining whether the filter screen needs cleaning. The differential pressure sensor is located inside the protective cover for protection. This system utilizes a cost-effective and energy-saving electric valve and features an internal... The electric three-way valve with limit contacts and manual function optimizes control logic and energy consumption. Secondly, intelligent monitoring and program control through differential pressure sensors enable on-demand backwashing, avoiding unnecessary energy waste. Thirdly, backwashing is performed using internal water circulation, reducing external water consumption. Finally, the combination of automatic backwashing and convenient manual cleaning mechanisms reduces energy consumption increases caused by blockages. Thus, this energy-saving water treatment equipment achieves significant energy savings while ensuring treatment effectiveness. It also solves the technical problem that when treating wastewater, the limited contact area between the scraper and the filter screen allows some impurities to remain on the filter screen, gradually accumulating and causing blockages that affect filtration efficiency.

[0022] 2. By setting up a fixing device, the fixing frame is fixed. Stainless steel springs are fixedly installed to the fixing block and the water tank respectively. After the fixing block moves, it returns to its original position. The arc groove of the fixing block contacts the round rod of the fixing frame to fix the fixing frame. The slider is composed of two truncated cones of different sizes. The larger truncated cone is the same size as the truncated cone of the fixing frame and the two are symmetrically arranged. The smaller truncated cone on the slider slides into the truncated cone groove of the fixing frame. The bottom surface of the larger truncated cone of the slider contacts the bottom surface of the truncated cone of the fixing frame, forming a double truncated cone structure. Due to its structural features, it is easy to fix the fixing block to the truncated cone of the fixing frame and then release it, thereby fixing the wedge-shaped filter screen tube fixed to the fixing frame. This solves the technical problem that when treating sewage, high viscosity or high concentration suspended solids easily adhere to the filter screen, forming a difficult-to-remove dirt layer, and scraper cleaning cannot completely remove the dirt adhering to the filter screen.

The cover 2 is fixedly installed to the water tank 1 by bolts, which facilitates both fixing and disassembly. The water tank 1 is fixedly connected to the drain tee pipe 21 that drives the electric three-way valve, which facilitates the control of the flow direction of the filtered water. An adsorption water purification device is installed inside the water tank 1. Since the adsorption water purification device is a mature existing technology, it is not described in detail in this utility model. The operator can select a suitable adsorption water purification device according to actual needs, such as activated carbon adsorption, ion exchange resin, etc.

[0034] To ensure the wedge-shaped filter tube 3 is not easily damaged during long-term use, it is slidably inserted into the groove on the top left side of the water tank 1. The left end of the wedge-shaped filter tube 3 is threadedly connected to an inlet tee pipe 31 with an electric three-way valve, and the right end is threadedly connected to an outlet pipe 32 with an electric valve. The wedge-shaped filter tube 3 is made of stainless steel. The slidable insertion of the wedge-shaped filter tube 3 into the water tank 1 provides both fixation and easy removal. The threaded connection between the wedge-shaped filter tube 3 and the inlet tee pipe 31 also facilitates disassembly. The electric three-way valve can be adjusted as needed. The water flow is controlled by a wedge-shaped filter tube 3 connected to the outlet pipe 32 via a threaded connection. This connection allows for easy disassembly while maintaining the filter tube's fixation. The wedge-shaped filter tube 3 is made of stainless steel, which offers excellent corrosion resistance and mechanical strength, ensuring that it is not easily damaged during long-term use and is easy to clean. The electric valve used in the filtration device can be the Hailin Energy Saving HL-G2-3 / 4-S2, which offers high cost-effectiveness and significant energy-saving performance. The electric three-way valve can be the ZLDF-320, which features a built-in limit contact switch and supports manual valve opening, facilitating debugging and energy-saving operation.

[0035] To prevent water leakage, two silicone rings 4 are fixedly bonded to the outer surface of the wedge-shaped filter tube 3. The left side of one silicone ring 4 contacts the right end of the right water pipe of the inlet tee pipe 31, and the right side of the other silicone ring 4 contacts the left end of the outlet pipe 32. The wedge-shaped filter tube 3 is fixedly bonded to the silicone rings 4, which not only fixes it but also facilitates replacement. The contact of one silicone ring 4 with the right end of the right water pipe of the inlet tee pipe 31 and the contact of the other silicone ring 4 with the left end of the outlet pipe 32 seals it and prevents water leakage.

[0036] To protect the differential pressure sensor 5, a differential pressure sensor 5 is threadedly connected to the outer surface of the right end of the inlet tee pipe 31 and the inner wall of the threaded groove of the outlet pipe 32. A protective cover 51 is fixedly bonded to the outer surface of both the right end of the inlet tee pipe 31 and the outlet pipe 32 using waterproof adhesive. The differential pressure sensor 5 is located inside the protective cover 51, and is threadedly connected to the inlet tee pipe 31 and the outlet pipe 32 respectively through two positive pressure ports. This design allows for easy disassembly while maintaining its secure position. The differential pressure sensor 5 can be used to detect the pressure difference across the wedge-shaped filter pipe 3. This allows for the determination of whether the filter needs cleaning. The differential pressure sensor 5 can be a Honeywell 26PC series, which features high precision and corrosion resistance, making it suitable for fluid pressure detection. The two protective covers 51 are fixed to the inlet tee pipe 31 and the outlet pipe 32 respectively using waterproof adhesive.

The protective cover 51 can be made of stainless steel, which has high strength and durability, can withstand certain mechanical impacts, and has excellent corrosion resistance, making it suitable for water treatment environments.

[0037] Wastewater is filtered by a filtration device. Water tank 1 is fixedly connected to drain tee 21, which drives an electric tee valve, facilitating control of the filtered water flow direction. Wedge-shaped filter tube 3 is threadedly connected to inlet tee 31. The electric tee valve can adjust the water flow direction as needed. Wedge-shaped filter tube 3 is threadedly connected to outlet pipe 32. One silicone ring 4 contacts the right end of the inlet tee 31, and another silicone ring 4 contacts the left end of the outlet pipe 32 for sealing. A differential pressure sensor 5 detects the pressure difference across the wedge-shaped filter tube 3, determining whether cleaning is needed. The differential pressure sensor 5 is located inside a protective cover 51 for protection. This system utilizes a high-performance, cost-effective design and supports energy-saving operation. The electric valves and electric three-way valves with built-in limit contacts and manual function optimize control logic and energy consumption. Secondly, through intelligent monitoring and program control of differential pressure sensor 5, on-demand backwashing is realized, avoiding ineffective energy waste. Thirdly, backwashing is carried out using internal water circulation, reducing external water consumption. Finally, the combination of automatic backwashing and convenient manual cleaning mechanism reduces the increase in energy consumption caused by blockage. Thus, this energy-saving water treatment equipment achieves significant energy-saving goals while ensuring treatment effect. It solves the technical problem that when treating sewage, the limited contact area between the scraper and the filter screen causes some impurities to remain on the filter screen, which gradually accumulates and leads to filter screen blockage, affecting filtration efficiency.

[0038] In order to fix the fixing frame 61, a fixing device is provided on the inner wall of the groove of the water tank 1. The fixing device includes a fixing block 7 and a fixing frame 61. The relative movement of the fixing block 7 fixes the fixing frame 61.

[0039] To fix and then release the truncated cone of the fixing frame 61, the fixing device also includes a slider 6. The slider 6 is slidably sleeved on the round rod surface of the fixing frame 61. The right truncated cone surface of the slider 6 is slidably connected to the inner wall of the truncated cone groove of the fixing frame 61. The fixing frame 61 is fixedly installed on the outer surface of the wedge-shaped filter tube 3. By sliding the slider 6 to the fixing frame 61, it is fixed without affecting its movement. The slider 6 is composed of two truncated cones of different sizes. The larger truncated cone is the same size as the truncated cone of the fixing frame 61 and the two are symmetrically arranged. The smaller truncated cone on the slider 6 is slidably connected into the truncated cone groove of the fixing frame 61. The bottom surface of the larger truncated cone of the slider 6 contacts the bottom surface of the truncated cone of the fixing frame 61, forming a double truncated cone structure. Due to its structural features, it is convenient for the fixing block 7 to fix and then release the truncated cone of the fixing frame 61.

[0040] To secure the wedge-shaped filter tube 3, which is fixedly installed with the mounting bracket 61, the fixing block 7 is slidably inserted into the groove on the left side of the top of the water tank 1. The arcuate groove of the fixing block 7 contacts the round rod surface of the mounting bracket 61. A stainless steel spring 71 is fixedly installed on the outer side of the fixing block 7. The stainless steel spring 71 is fixedly installed in the groove on the left side of the top of the water tank 1. By sliding the fixing block 7 into the water tank 1, it is fixed without affecting its movement. The mounting bracket 61 is fixed by contacting the round rod of the mounting bracket 61 through the arcuate groove of the fixing block 7. The stainless steel spring 71 is fixedly installed with the fixing block 7 and the water tank 1 respectively. After the fixing block 7 moves, it is reset to fix the mounting bracket 61, thereby fixing the wedge-shaped filter tube 3, which is fixedly installed with the mounting bracket 61.

[0041] The fixing device is used to fix the fixing frame 61. The stainless steel spring 71 is fixedly installed with the fixing block 7 and the water tank 1 respectively. After the fixing block 7 moves, it is reset. The arc groove of the fixing block 7 contacts the round rod of the fixing frame 61 to fix the fixing frame 61. The slider 6 is composed of two truncated cones of different sizes. The larger truncated cone is the same size as the truncated cone of the fixing frame 61 and the two are symmetrically arranged. The smaller truncated cone on the slider 6 slides into the truncated cone groove of the fixing frame 61. The bottom surface of the larger truncated cone of the slider 6 contacts the bottom surface of the truncated cone of the fixing frame 61 to form a double truncated cone structure. Due to its structural features, it is easy for the fixing block 7 to fix the truncated cone of the fixing frame 61 and then release the fixation, thereby fixing the wedge-shaped filter screen tube 3 fixedly installed with the fixing frame 61. This solves the technical problem that when treating sewage, high viscosity or high concentration suspended solids are easy to adhere to the filter screen and form a difficult-to-remove dirt layer. The scraper cleaning cannot completely remove the dirt adhering to the filter screen.

[0042] Working principle: When the wedge-shaped filter tube 3 needs to be installed, the operator slides the wedge-shaped filter tube 3 into the groove of the water tank 1. The truncated cone of the fixed bracket 61 fixed on it contacts the fixed block 7. Due to the shape design of the truncated cone on the fixed bracket 61, the fixed block 7 is squeezed and moves in the water tank 1 where it is slidably inserted. When the right side of the fixed block 7 contacts the bottom surface of the truncated cone of the fixed bracket 61, the stainless steel spring 71 resets it. The arc groove on the fixed block 7 contacts the round rod of the fixed bracket 61 and clamps the fixed bracket 61, thereby fixing the wedge-shaped filter tube 3.

[0043] After installation, the staff will thread the inlet tee pipe 31 with the electric three-way valve to the left end of the wedge filter pipe 3 until the right end of the inlet tee pipe 31 contacts a silicone ring 4 on the wedge filter pipe 3. Then, thread the outlet pipe 32 with the electric valve to the right end of the wedge filter pipe 3 until it contacts another silicone ring 4. When installing the outlet pipe 32, make sure that the inlet pipe is fixedly connected to it is at the top. Then, connect the water pump inlet end to the left pipe of the drain tee pipe 21 through a hose. The right pipe of the drain tee pipe 21 is fixedly connected to the water storage tank 1 through a hose. Connect the inlet pipe fixedly connected to the outlet pipe 32 to the hose. Pass one end of the hose through the round hole of the tank cover 2 and fix it to the outlet end of the water pump. After installation, fix the tank cover 2 to the upper surface of the water tank 1 with bolts.

[0044] When sewage needs to be filtered, the inlet tee pipe 31 closes the lower pipe channel through its electric tee valve, and the drain tee pipe 21 closes the right end pipe channel. Sewage is injected from the upper pipe of the inlet tee pipe 31 and enters the wedge-shaped filter pipe 3 for preliminary filtration, intercepting suspended solids and particulate impurities. The water after preliminary filtration through the wedge-shaped filter pipe 3 enters the water tank 1, which is equipped with adsorption water purification equipment, such as activated carbon adsorption and ion exchange resin, for further filtration to remove dissolved pollutants and odors. The filtered water enters the storage tank.

[0045] The differential pressure sensor 5 is installed on the inlet tee pipe 31 and the outlet pipe 32 to monitor the pressure difference on both sides of the wedge filter pipe 3. When the differential pressure sensor 5 detects that the pressure difference on both sides of the wedge filter pipe 3 is too large, it indicates that the wedge filter pipe 3 is blocked. The control system analyzes the detection result of the differential pressure sensor 5 and controls the electric three-way valve of the inlet tee pipe 31 through the program to close the channel of the upper pipe and control the drain tee pipe 21 to close the channel of the left pipe. Then, the water pump is started to draw water from the water tank 1 and deliver it to the outlet pipe 32. At this time, the water in the water tank 1 will flow back through the wedge filter pipe 3 to backwash the wedge filter pipe 3. The cleaned water flows out through the pipe below the inlet tee pipe 31. The protective cover 51 outside the differential pressure sensor 5 protects it from contamination or mechanical damage.

[0046] After backwashing the wedge-shaped filter tube 3, the differential pressure sensor 5 still detected an excessive pressure difference on both sides, indicating that high-viscosity or high-concentration suspended matter may be attached to the filter screen, requiring manual cleaning. The operator first removed the outlet pipe 32 and the inlet tee pipe 31, then pushed the wedge-shaped filter tube 3 to the right. The fixing block 7 slid on the round rod of the fixing frame 61. Due to the structural design of the slider 6, the fixing block 7 was squeezed. When the fixing block 7 moved to the top surface of the large truncated cone of the slider 6, the operator pulled the wedge-shaped filter tube 3 to the left. During this process, the fixing block 7 slid and moved, making it slide and connect with the truncated cone groove of the fixing frame 61. After the bottom surface of the large truncated cone of the slider 6 contacted the bottom surface of the truncated cone of the fixing frame 61, a double truncated cone structure was formed. This structural design allows the fixing block 7 to move smoothly to the top surface of the truncated cone of the fixing frame 61 under the action of the leftward pulling force. At this time, the wedge-shaped filter tube 3 can be easily removed and the high-viscosity or high-concentration suspended matter on it can be cleaned.

[0047] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
