Large impurities in the water are filtered through the filter core. After the filtered water enters the threaded cover B, the threaded cover B is connected to the booster pump through a flexible conduit, so that the booster pump extracts water from the threaded cover B and transports it to the ultrafiltration device body through the connecting pipe, thereby causing a large number of large particle impurities to enter the ultrafiltration device body, causing the ultrafiltration membrane in the ultrafiltration device body to be blocked.

[0004] However, the above-mentioned disclosed solution has the following shortcomings: the anti-blocking mechanism on the threaded cover can easily cause large sand to be blocked in the filter air inside the sleeve. When the blockage reaches a certain level, the water flow rate will be reduced. In severe cases, it will cause the sleeve to be blocked, reducing the efficiency of the ultrafiltration equipment.

DETAILED DESCRIPTION

[0019] Example 1

[0020] like Figure 1 、 Figure 3 and Figure 4 As shown, the utility model proposes an ultrafiltration device for softening water, including a filter box 1, a sealing cover 2, a filtering mechanism and an anti-blocking mechanism; a water pump 401 is installed at the output end of the filter box 1, and an ultrafiltration device body 4 is installed at the output end of the water pump 401; the sealing cover 2 is detachably connected to the input end of the filter box 1 by bolts, and a water inlet valve 201 is provided on the sealing cover 2; the filtering mechanism is installed on the sealing cover 2, and is used to filter the water entering the filter box 1 step by step, and the filtering mechanism is slidably connected to the inner wall of the filter box 1; the anti-blocking mechanism is adjustably arranged on the filtering mechanism, and is used to dredge the filtering mechanism to prevent blockage.

[0021] Furthermore, the filtering mechanism includes a filter plate 203 and a connecting rod 202; two groups of filter plates 203 are provided, and both groups of filter plates 203 are provided with multiple groups of filter holes 204, and the filter plates 203 are slidably connected to the inner wall of the filter box 1; multiple groups of connecting rods 202 are provided, and two groups of filter plates 203 are connected by connecting rods 202, and one group of filter plates 203 is connected to the sealing cover 2 through the connecting rod 202.

[0022] Furthermore, the diameter of the filter holes 204 on a group of filter plates 203 close to the sealing cover 2 is larger than the diameter of the filter holes 204 on a group of filter plates 203 away from the sealing cover 2, which facilitates the step-by-step filtration of impurities in the water, reduces the filtration pressure of the filter plates 203, and improves the filtration efficiency.

[0023] Furthermore, the anti-blocking mechanism includes an adjusting rod 3, a mounting plate 301 and an elastic rod 303; one end of the adjusting rod 3 is slidably connected to the sealing cover 2, and the other end is slidably connected to the filter plate 203; two groups of mounting plates 301 are provided, the mounting plates 301 are installed on the adjusting rod 3 and are located on the output end side of the filter plate 203, and multiple groups of cleaning rods 302 are evenly arranged on the mounting plate 301, the cleaning rods 302 correspond to the filter holes 204, and multiple groups of water passages are opened on the mounting plate 301 to avoid interfering with water circulation; the elastic rod 303 is installed between the mounting plate 301 and the filter plate 203, and the elastic rod 303 is composed of a telescopic rod and a spring sleeved on the outside thereof.

[0024] Furthermore, the length of the cleaning rod 302 is greater than the thickness of the filter plate 203, and the cross-sectional diameter of the cleaning rod 302 is smaller than the diameter of the filter hole 204, so that the cleaning rod 302 can unclog the filter hole 204 without interfering with the passage of water through the filter hole 204.

[0025] After the filter 204 is blocked by impurities, the handheld adjusting rod 3 is pulled along the sealing cover 2 to compress the elastic rod 303, thereby driving the mounting plate 301 to move toward the filter plate 203 until the cleaning rod 302 is inserted into and passes through the filter hole 204, pushing the impurities blocked in the filter hole 204 to achieve a dredging effect. The dredged impurities fall into the bottom end of the filter box 1. When the adjusting rod 3 is released, the elastic force of the elastic rod 303 restores the mounting plate 301 to its original position. This process is repeated to dredge the filter plate 203 and avoid blocking the water flow.

[0026] Example 2

[0027] like Figure 1 、 Figure 2 and Figure 4 As shown, the utility model proposes an ultrafiltration device for softening water. Compared with the first embodiment, the bottom end of the filter box 1 is provided with a discharge port 101 corresponding to the filter plate 203, and the bottom end of the discharge port 101 is provided with a collecting box 102 located on the filter box 1, and a drain valve 103 is provided on the side wall of the collecting box 102, and a door body is provided at the front end of the collecting box 102.

[0028] Furthermore, the anti-blocking mechanism also includes a sliding rod 304 and a cover plate 305; one end of the sliding rod 304 is connected to the bottom end of the mounting plate 301; the cover plate 305 is abutted against the bottom end of the side wall of the filter plate 203, and the cover plate 305 is slidably connected to the bottom end of the inner wall of the filter box 1, and the cover plate 305 is used to block the discharge port 101, and the other end of the sliding rod 304 passes through the filter plate 203 and is connected to the cover plate 305, and the sliding rod 304 is slidably connected to the filter plate 203.

[0029] In this embodiment, when the mounting plate 301 moves toward the filter plate 203, the cover plate 305 is driven by the sliding rod 304 to slide along the bottom end of the filter box 1 away from the filter plate 203, thereby opening the discharge port 101. When the cleaning rod 302 pushes the impurities on the filter holes 204, the impurities fall into the collection box 102 through the discharge port 101 and are collected. When the mounting plate 301 drives the cleaning rod 302 away from the filter plate 203, the cover plate 305 slides along the bottom end of the filter box 1 until it abuts against the bottom end of the filter plate 203, sealing the discharge port 101 to prevent impurities in the collection box 102 from being scattered inside the filter box 1 and continuing to block the filter holes 204. After using it for a period of time, open the drain valve 103 to drain the water in the collection box 102 first, and then open the door of the collection box 102 to take out the impurities.

[0030] Example 3

[0031] like Figure 1 As shown, the present invention proposes an ultrafiltration device for softening water. Compared with Example 1, two groups of filter boxes 1, sealing covers 2, filter mechanisms and anti-blocking mechanisms are provided. The output ends of the two groups of filter boxes 1 are connected to the input ends of the water pump 401 through three-way pipes 402, and a solenoid valve is provided at the connection between the three-way pipe 402 and the filter box 1.

[0032] In this embodiment, it is convenient for the two groups of filter boxes 1 to work alternately. When one group of filter boxes 1 needs to undergo daily maintenance or clean impurities inside the collection box 102, the other group of filter boxes 1 can be put into operation by adjusting the solenoid valve. The operations of the two groups of filter boxes 1 do not interfere with each other, thereby improving the filtration efficiency.

[0033] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited thereto. Various changes can be made within the knowledge scope of those skilled in the art without departing from the purpose of the present invention.
