Description

Technical Field

[0001] This utility model relates to the field of filtration device technology, and in particular to a filtration device for water tanks that is easy to clean. Background Technology

[0002] Domestic water refers to water that meets relevant standards and is used for daily life and production after being purified and disinfected by water treatment plants. Domestic water is mainly drawn from rivers, lakes, groundwater, and surface water by water plant intake pumping stations. After treatment processes such as sedimentation, disinfection, and filtration, it is finally transported to various locations via distribution pumping stations and is generally stored in water tanks for later use. Water tanks have water storage and regulation functions. Common water tanks are non-welded assembled tanks with a galvanized steel outer layer and a polyethylene inner layer. They typically consist of a tank body, inlet pipe, outlet pipe, and overflow pipe. They do not have filtration devices, and impurities inevitably enter through the overflow pipe during storage. Therefore, domestic water needs to be filtered before being delivered to users.

[0003] Existing water tank filtration systems typically filter water by adding filter media. Due to the large size of these systems, cleaning the filter media is extremely difficult. It usually requires manual removal of the filter media and hand rinsing, which is very time-consuming and significantly reduces cleaning efficiency. Furthermore, infrequent cleaning and poor cleaning results can lead to secondary water pollution.

[0004] Therefore, we propose an easy-to-clean filtration device for water tanks to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a water tank filter that is easy to clean, solving the problems of difficult and inefficient cleaning of existing filter devices.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A water tank with an easy-to-clean filtration device includes a base plate, a filter tank fixedly connected to the top of the base plate, buffer tanks on both sides of the filter tank, and the two buffer tanks are connected to each other by a centrifugal water pump. The centrifugal water pump can be used to guide the water flow in both directions between the two buffer tanks and the filter tank. Two filter plates are provided on both sides of the inside of the filter tank. The outside of the two buffer tanks are connected to water inlet flanges, and one side of the filter tank is connected to water outlet flanges.

[0008] Preferably, one side of each of the two buffer tanks is connected to a water storage tank via a connecting pipe. The water storage tank is used to store the wastewater generated during the cleaning process, and the top of the water storage tank is provided with a vent for ventilation.

[0009] Preferably, valves for switching the water pipes are installed on both the inlet flange and the outlet flange.

[0010] Preferably, the filter plate is slidably connected to the water filter box via a sliding groove inside the water filter box, and a filter media cover is fixedly connected to the top of the filter plate to facilitate lifting the filter plate.

[0011] Preferably, the bottom of the water tank is provided with a drain hole for sewage discharge, and a plug is installed inside the drain hole.

[0012] Preferably, the volume of the filter tank is larger than the volume of the buffer tank, and the volume of the storage tank is larger than the volume of the buffer tank.

[0013] This utility model has at least the following beneficial effects:

[0014] Connect the water outlet pipe of the water tank to the water inlet flange, open all valves, and water enters the buffer tank. Under the action of the centrifugal water pump, water enters the filter tank. When passing through the filter plate, impurities are blocked by the filter plate, and water flows out of the filter device through the water inlet flange. When cleaning is required, first close the valve on the water outlet flange, and when there is a certain amount of water in the filter device, close the valve on the water inlet flange. By turning one centrifugal water pump forward and the other centrifugal water pump in reverse, the water flow is made to flow unidirectionally throughout the filter device to rinse the filter plate. Then, reverse the two centrifugal water pumps to make the water flow in the opposite direction to rinse the filter plate again, thereby realizing automatic cleaning of the filter plate, which greatly improves the cleaning efficiency and cleanliness.

[0015] This utility model also has the following beneficial effects:

[0016] When the centrifugal water pump guides the water flow in both directions to wash the filter plates, the buffer tank is connected to the storage tank through a connecting pipe. When the water flows back and forth in the entire device, it is difficult to maintain operation by relying solely on the water in the buffer tank. When all the water in one buffer tank is pumped into the other buffer tank, the water in the storage tank will flow into the buffer tank to maintain the operation of the cleaning process. After cleaning, the wastewater can be drained through the drain hole at the bottom of the storage tank to achieve a better cleaning effect. At the same time, the bottom of the storage tank is also provided with a vent for ventilation to prevent air from being trapped in the filtration device and affecting the filtration effect.

[0024] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0025] Reference Figure 1-5 A water tank filtration device for easy cleaning includes a base plate 1, a filter tank 2 fixedly connected to the top of the base plate 1, buffer tanks 3 on both sides of the filter tank 2, and the two buffer tanks 3 are connected by a centrifugal water pump 5. The centrifugal water pump 5 can be used to guide the water flow in both directions between the two buffer tanks 3 and the filter tank 2. By setting the two centrifugal water pumps 5 to a forward and reverse operating mode, the water flow is made to run in one direction throughout the device. Then, by changing the operating mode of the two centrifugal water pumps 5, the water flow is made to run in the opposite direction. Two filter plates 10 are provided on both sides of the inside of the filter tank 2. The outside of the two buffer tanks 3 are connected to a water inlet flange 6, and one side of the filter tank 2 is connected to a water outlet flange 14.

[0026] Based on the above work process, it can be concluded that:

[0027] During filtration, all valves 7 are open. When cleaning is required, first close valve 7 on outlet flange 14. After the filter device is filled with enough water, close valve 7 on both inlet flanges 6. Run the two centrifugal water pumps 5 in a forward and reverse rotation mode to make the water flow unidirectionally in the filter device and rinse one side of filter plate 10. Then, reverse the working direction of the two centrifugal water pumps 5 to make the water flow unidirectionally in the opposite direction and rinse the other side of filter plate 10 to clean the filter plate.

[0028] Furthermore, one side of each of the two buffer tanks 3 is connected to a water storage tank 4 via a connecting pipe 11. The water storage tank 4 is used to store the wastewater generated during the cleaning process. The top of the water storage tank 4 is provided with a vent hole 9 for ventilation to prevent the air pressure inside the filter device from affecting the overall cleaning effect. The bottom of the water storage tank 4 is provided with a drain hole 12 for wastewater discharge, and a water plug 13 is installed inside the drain hole 12. After cleaning, the wastewater can be drained by opening the water plug 13.

[0029] Furthermore, valves 7 for switching the water pipes are installed on both inlet flanges 6 and outlet flanges 14. When cleaning is required, the outlet flange 6 is closed first, and then the inlet flange 14 is closed.

[0030] Furthermore, the filter plate 10 is slidably connected to the water filter tank 2 through a sliding groove 15 opened inside the water filter tank 2, and a filter media cover 8 is fixedly connected to the top of the filter plate 10 to facilitate lifting the filter plate 10. The filter media cover 8 can be opened to replace the filter plate 10. When the filter plate 10 is insufficient to meet the filtration requirements, a higher specification filter media can be added between two filter plates 10 that are close to each other to meet higher filtration requirements.

[0031] Furthermore, the volume of the filter tank 2 is larger than that of the buffer tank 3, and the volume of the storage tank 4 is larger than that of the buffer tank 3, in order to ensure the filtration speed and that there is always water flowing in the filter tank 2 and the buffer tank 3 during the cleaning process, so as to achieve a better cleaning effect.

[0032] In summary:

[0033] During the cleaning operation, the centrifugal water pump 5 is rotated to make the water flow repeatedly move in one direction in the filter device. During the cleaning process, all the water required for operation is stored in the water tank 4. At the same time, the air pressure difference inside and outside the water tank 4 is balanced through the vent 12 on the top of the two water tanks 4 to ensure the normal operation of the cleaning operation. After rotating several times, both centrifugal water pumps 5 are rotated in reverse. At the same time, the water plug 13 at the bottom of the water tank 4 is opened so that all the wastewater after cleaning is discharged from the drain hole 12, and the cleaning is completed.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely principles of this utility model.
