[0022] As Figures 1 to 3 shown, the filter element flushing device 100 of the present utility model is used to flush the filter element 200. The filter element flushing device 100 includes a water inlet pipe 1, a filtering component 2 communicated with the water inlet pipe 1, a flushing component 3 communicating one end of the filtering component 2 and the filter element 200, a shunt pipe 4, a water outlet pipe 5 for discharging the water from the other end of the filter element 200, a drain pipe 6 communicated with the water outlet pipe 5, a return pipe 7 communicating the water outlet pipe 5 and the water inlet pipe 1, a circulation control valve 8 communicating the water outlet pipe 5, the drain pipe 6 and the return pipe 7, a circulation three-way valve 9 communicating the water inlet pipe 1, the return pipe 7 and the filtering component 2, a flushing booster pump 10 communicating the filtering component 2 and the flushing component 3, a flushing control valve 11 for controlling the flushing water pressure, a water inlet pressure gauge 12 for detecting the flushing pressure, a workbench 13 and a support frame 14.

[0023] The workbench 13 is arranged above the support frame 14 and is used to place the filter element 200. In this embodiment, the flushing component 3 is arranged above the workbench 13.

[0024] The filtering component 2 and the water inlet pipe 1 are arranged inside the support frame 14. A plurality of universal wheels 141 are arranged below the support frame 14, which is convenient for pushing the filter element flushing device 100 to a suitable working position.

[0025] The water inlet pipe 1 is used to introduce cleaning water. During direct-drain cleaning, the water inlet pipe 1 conducts water. After passing through the filter assembly 2, the flushing assembly 3, and the filter element 200 in sequence, it is discharged through the water outlet pipe 5 and the drain pipe 6.

[0026] The filter assembly 2 includes a primary filter 21 for coarse filtration and a secondary filter 22 for fine filtration that are connected in sequence. The primary filter 21 is arranged at one end close to the water inlet pipe 1. The filter assembly 2 can filter out impurity particles in direct flushing or circulating water, ensuring that the water flowing into the filter element 200 meets the flushing water standard.

[0027] The flushing booster pump 10 is used to pump the water passing through the filter assembly 2 into the flushing assembly 3. The flushing control valve 11 can control the flushing water pressure, control different flushing pressures in different cleaning processes, or adopt different pressures for different filter elements 200, and the water inlet pressure gauge 12 can detect the water pressure introduced into the flushing assembly 3.

[0028] The number of the filter elements 200 is multiple. The shunt pipe 4 is used to connect the flushing booster pump 10 and the flushing assembly 3. The shunt pipe 4 has multiple water supply ports, and each water supply port corresponds to one filter element 200.

[0029] The flushing assembly 3 includes a flushing injector 31 that connects one water supply port and one filter element 200, a pressing cylinder 32 for pressurizing the flushing injector 31, and a one-way control valve 33 for controlling the flushing injector 31 to supply water to each filter element 200.

[0030] The flushing injector 31 is used to flush water into the filter element 200, and the flushing injector 31 plays the roles of positioning, pressing, sealing, and flushing with water.

[0031] The pressing cylinder 32 can increase the water outlet pressure of the flushing injector 31, and the one-way control valve 33 can control the flushing injector 31 corresponding to the filter element 200 to be cleaned to discharge water.

[0032] The one-way control valve is in an open state during cleaning.

[0033] A water tank 15 for collecting cleaning water is provided below the other end of the filter element 200. The water tank 15 is communicated with the water outlet pipe 5. The water for cleaning the filter element 200 falls into the water tank 15 and flows into the water outlet pipe 5 through the guiding tooling 16 at the bottom of the water tank 15.

[0034] The circulating control valve 8 has a first state in which the water outlet pipe 5 discharges water towards the drain pipe 6 and a second state in which it discharges water towards the return pipe 7. When the circulating control valve 8 is in the first state, the filter element flushing device 100 is in a direct discharge cleaning mode, and the cleaning water is directly discharged after flushing the filter element 200. When the circulating control valve 8 is in the second state, the filter element flushing device 100 is in a circulating cleaning mode, and the cleaning water flows back to the return pipe 7 after flushing the filter element 200 for reuse.

[0035] The circulating three-way valve 9 is used to control the connection between the water inlet pipe 1 or the return pipe 7 and the filtration assembly 2. When the circulating control valve 8 is in the first state, the circulating three-way valve 9 is connected to the water inlet pipe 1, and when the circulating control valve 8 is in the second state, the circulating three-way valve 9 is connected to the return pipe 7.

[0036] In the circulating cleaning mode, the circulating water passes through the primary filter 21 and the secondary filter 22 in sequence to filter out the particles introduced into the water due to flushing, making it pure water that can be recycled.

[0037] The water flow path in the direct discharge cleaning mode is as follows: Water flows in from the water inlet pipe 1, passes through the filtration of the filtration assembly 2, then flushes into the filter element 200 through the flushing assembly 3, and the flushed sewage enters the water outlet pipe 5 from the bottom of the water tank 15 and is discharged from the drain pipe 6. This mode is suitable for flushing the filter element 200 when it is relatively dirty at the beginning and directly discharging the dirty water.

[0038] The water flow path in the circulating cleaning mode is as follows: Water flows in from the return pipe 7, passes through the filtration of the filtration assembly 2, then flushes into the filter element 200 through the flushing assembly 3, and the flushed sewage enters the water outlet pipe 5 from the bottom of the water tank 15 and then passes through the filtration assembly 2 again from the return pipe 7. This mode is suitable for being carried out after a certain period of the direct discharge cleaning mode. At this time, the product is circulated and flushed. The cleaning is cleaner in this mode and water can be saved.

[0039] The filter element flushing device 100 of the present utility model can achieve the discharge or recycling of the flushing water by setting the circulating control valve 8, adopt different modes under different cleaning degrees of the filter element 200, thereby shortening the product flushing time, improving the cleanliness of the product after flushing, enhancing the flushing efficiency, and achieving the water-saving effect.

[0040] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as falling within the scope described in this specification.

[0041] The above-described embodiments merely represent several implementation manners of the present utility model. The description thereof is relatively specific and detailed, but it should not be construed as a limitation to the scope of the utility model patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all fall within the protection scope of the present utility model. Therefore, the protection scope of the present utility model patent shall be subject to the appended claims.
