Description
Technical Field
[0001] This utility model relates to the field of wastewater treatment technology, specifically to a wastewater purification device for water dispensers. Background Technology
[0002] A wastewater purification device for water dispensers is a device used to treat the wastewater generated during the operation of water dispensers in order to purify the wastewater. The wastewater purification device is usually composed of a wastewater collection system, a filtration system, a purification treatment system, and a sewage discharge system. In use, the wastewater first enters the wastewater collection system and is then transported to the filtration system. At this time, the wastewater passes through each stage of filter cartridges in sequence, and different filter cartridges play their respective filtration roles, gradually removing impurities and pollutants from the water. Among them, water dispensers in public places have a large number of users and a large amount of wastewater discharge.
[0003] For example, Chinese patent CN206529355U, entitled "A Wastewater Recycling Device for a Water Dispenser," includes a leakage tank, a purification module, a water storage tank, a water pump, a core control module, and a heating kettle. The leakage tank is connected to the purification module via a water pipe, the purification module is connected to the water storage tank via a water pipe, the water storage tank is connected to the water pump via a water pipe, and the water pump is connected to the heating kettle via a water pipe. The core control module is connected to the water level detection module in the water storage tank and the water pump via wires. The purification module is used to filter and purify the leakage wastewater so that the purified water meets drinking water standards. The water storage tank contains the water level detection module.
[0004] While the existing technologies can treat wastewater from water dispensers, in practical use, filter replacement is not convenient. Filters are typically fixed within the filtration mechanism, requiring disassembly and reassembly of the entire fixed structure for replacement, thus reducing maintenance efficiency. Furthermore, it is difficult to monitor the wastewater volume, as wastewater is usually pumped into the filter tank, leaving operators unsure of the volume and reducing filtration effectiveness. Therefore, these technologies do not meet current needs. To address this, we propose a wastewater purification device for water dispensers. Utility Model Content
[0005] The purpose of this invention is to provide a wastewater purification device for water dispensers, in order to solve the problems mentioned in the background art, such as inconvenient filter replacement and difficulty in observing the amount of wastewater entering the system.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a wastewater purification device for a water dispenser, comprising a base, a filter tank disposed above the base, a fixed frame disposed below the interior of the filter tank, three rotating cavities disposed around the interior of the fixed frame, the rotating cavities being equidistantly distributed from top to bottom, and the side of the rotating cavities closest to the center of the fixed frame being an open structure, a reset cavity disposed inside the front and rear ends of the fixed frame at both ends of the rotating cavities, the reset cavity communicating with the rotating cavity, an installation rod disposed inside the reset cavity, the front and rear ends of the installation rod being rotatably connected to the inner wall of the rotating cavity, a support seat fixedly disposed outside the installation rod in the rotating cavity, one end of the support seat extending to the outside of the rotating cavity, and the other end of the support seat contacting the rotating cavity.
[0007] Preferably, the mounting rod is fitted with a torsion spring on its outer side in the rotating cavity. The two ends of the torsion spring are fixedly connected to the inner wall of the rotating cavity and the support seat, respectively. The side wall of the filter tank is provided with slots that are evenly distributed and have an open structure at the top. The fixed frame is provided with four snap-fit plates on its outer side. One end of the snap-fit plate extends into the slot. The snap-fit plate slides with the slot and is fixed to the slot by bolts.
[0008] Preferably, a liquid indicator tube is fixedly installed on the lower side of one side of the filter tank. Both ends of the liquid indicator tube are connected to the filter tank, and the height of the lower end of the liquid indicator tube is lower than the height of the fixing frame. Two clamping frames are provided on the outside of the liquid indicator tube. The clamping frames clamp and fix the liquid indicator tube, and one side of the clamping frames is fixedly connected to the filter tank.
[0009] Preferably, the upper end of the filter tank is provided with a tank cover, the tank cover and the filter tank are connected by a snap fastener, and a water inlet pipe is fixedly provided at the upper end of the tank cover, the water inlet pipe is connected to the filter tank.
[0010] Preferably, a mounting base is fixedly provided at the lower end of the tank cover, and a filter cylinder is provided at the lower end of the mounting base. The filter cylinder is connected to the mounting base by a thread, and the filter cylinder is connected to the water inlet pipe.
[0011] Preferably, a filter plate is provided at the upper end of the support base, the filter plate is slidably engaged with the fixed frame, and the filter plate is snapped and fixed to the support base, and the mesh aperture inside the uppermost filter plate is smaller than the mesh aperture inside the filter cylinder.
[0012] Preferably, a support frame is fixedly installed at each of the four corners of the lower end of the filter tank, and the lower end of the support frame is fixedly connected to the base. A liquid outlet pipe is fixedly installed at the center of the lower end of the filter tank, and a valve is fixedly installed on the outside of the liquid outlet pipe.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] (1) This utility model allows for quick assembly and disassembly of the filter plate using a torsion spring and a support base. When the filter plate is being disassembled and maintained, the fixing frame has already been removed from the filter tank. At this time, the fixing frame is inverted, causing the filter plate to fall out of the fixing frame. Simultaneously, the torsion spring resets and drives the support base to rotate into the rotating cavity. When installing a new filter plate, the operator first pulls the lowest support base, causing the support base to rotate from a vertical state to a horizontal state. At the same time, the torsion spring is in a compressed state. Then, the new filter plate is aligned with the opening of the fixing frame and inserted into the fixing frame until the new filter plate is moved to the appropriate position. At this time, the lower end of the filter plate is locked and fixed with the support base. The above operation is repeated until the remaining filter plates are installed inside the fixing frame, thereby improving the convenience of filter plate replacement.
[0015] (2) This utility model can display the amount of wastewater poured in in real time through the liquid display tube and the clamping frame. When wastewater is being treated, all the wastewater that has been filtered is concentrated at the bottom of the filter tank. At this time, some wastewater flows into the liquid display tube. After a period of time, the liquid level in the liquid display tube is level with the liquid level of the wastewater inside the filter tank. At this time, the operator can observe the liquid level in the liquid display tube in real time to understand the liquid level of the wastewater in the filter tank and adjust the amount of wastewater poured in to avoid excessive wastewater pouring and overflow. At the same time, it can make the liquid level of the filtered wastewater lower than the height of the filter plate to avoid the filter being soaked.
[0016] (3) This utility model can perform preliminary filtration of impurities in waste liquid through the mounting base and filter cylinder. When treating wastewater, it is connected to the inlet pipe through the pipeline, so that the wastewater enters the filter tank through the inlet pipe. At this time, the wastewater first enters the filter cylinder, so that the mesh structure on the filter cylinder intercepts and filters the larger fixed particle impurities in the wastewater. After preliminary filtration, the wastewater drips to the bottom of the filter tank, thereby improving the efficiency of wastewater filtration. At the same time, when cleaning the filter cylinder, the filter cylinder is rotated, so that the filter cylinder rotates on the mounting base until the filter cylinder separates from the mounting base.

[0024] Please see Figure 2 , Figure 3 and Figure 4The fixed frame 14 has three rotating cavities 15 arranged around its interior. These cavities are equidistant from top to bottom, and each cavity has an open side near the center of the fixed frame 14. Reset cavities 19 are located inside the front and rear ends of the rotating cavities 15, communicating with them. A mounting rod 16 is installed inside each reset cavity 19, with its front and rear ends rotatably connected to the inner wall of the rotating cavity 15. A support base 17 is fixedly mounted on the outside of the mounting rod 16 within the rotating cavity 15, with one end extending to the outside of the rotating cavity 15. The other end contacts the rotating cavity 15. The mounting rod 16 is fitted with a torsion spring 20 on the outside of the rotating cavity 15. The two ends of the torsion spring 20 are fixedly connected to the inner wall of the rotating cavity 15 and the support seat 17, respectively. The inside of the side wall of the filter tank 3 is provided with slots 12. The slots 12 are evenly distributed and the upper end of the slots 12 is open. The outside of the fixing frame 14 is provided with four snap-fit plates 13. One end of the snap-fit plate 13 extends into the inside of the slot 12. The snap-fit plate 13 slides with the slot 12 and is fixed to the slot 12 by bolts, so that the filter plate 18 can be fixed by the support seat 17.
[0025] Please see Figure 1 and Figure 2 A liquid display tube 6 is fixedly installed on the lower side of one side of the filter tank 3. Both ends of the liquid display tube 6 are connected to the filter tank 3, and the height of the lower end of the liquid display tube 6 is lower than the height of the fixed frame 14. Two clamping frames 7 are provided on the outside of the liquid display tube 6.

[0027] Working principle: During use, wastewater is connected to the inlet pipe 5 through a pipeline, allowing it to enter the filter tank 3. The wastewater first enters the filter cylinder 11, where the mesh structure intercepts and filters larger fixed particles. The filtered wastewater drips to the bottom of the filter tank 3, and some flows into the display pipe 6. After a period of time, the liquid level in the display pipe 6 becomes level with the wastewater level inside the filter tank 3. The operator then observes the liquid level in the display pipe 6 to monitor the wastewater level in the filter tank 3 and adjusts the amount of wastewater added. When the filter plate 18 is disassembled for maintenance, the fixing frame 14 has been removed. Remove the filter plate 18 from the filter tank 3. At this time, invert the fixing frame 14 so that the filter plate 18 falls out of the fixing frame 14. At the same time, the torsion spring 20 resets and drives the support seat 17 to rotate into the rotating cavity 15. When installing the new filter plate 18, the operator first pulls the lowest support seat 17 so that the support seat 17 rotates from a vertical state to a horizontal state. At the same time, the torsion spring 20 is in a compressed state. Then, align the new filter plate 18 with the opening of the fixing frame 14 and insert it into the fixing frame 14 until the new filter plate 18 is moved to the appropriate position. At this time, the lower end of the filter plate 18 is locked with the support seat 17. Repeat the above operation until the remaining filter plates 18 are installed inside the fixing frame 14.
