However, when the liquid passes through the filter sponge and the filter screen, the filter sponge is usually placed before the resin layer to capture large particles of impurities in the liquid before entering the resin layer, and the filter mesh gasket is usually placed after the resin layer to further capture tiny particles in the liquid after the resin exchange to ensure the quality of the liquid. When the filter sponge and the filter screen are used to capture impurities, impurities will gradually accumulate, resulting in a decrease in the filtering effect. The above-mentioned socket-type isobaric liquid-inlet resin exchange column requires the disassembly of the fixed flange to extract the ion exchange column for convenient cleaning, and the cleaning work is not convenient and flexible. Therefore, those skilled in the art provide a socket-type isobaric liquid-inlet resin exchange column to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0025] This section will describe in detail the specific embodiments of the utility model. The preferred embodiments of the utility model are shown in the accompanying drawings. The purpose of the accompanying drawings is to supplement the description of the text part of the specification with graphics, so that people can intuitively and vividly understand each technical feature and the overall technical solution of the utility model, but it cannot be understood as a limitation on the protection scope of the utility model.

[0026] Reference Figure 3 , Figure 4 , Figure 5 and Figure 7 The utility model embodiment is a socket-type isobaric liquid-inlet resin exchange column, which includes an external shell 1, an ion exchange column 2, an exchange column top cover 3, a filter mesh gasket 4 and a filter sponge 5. The inner wall of the exchange column top cover 3 is fixedly connected to a fixed rod 6, and a rotatable connecting rod 7 is installed at the bottom of the fixed rod 6. The bottom of the connecting rod 7 penetrates the filter mesh gasket 4 and the filter sponge 5 in sequence, and is connected to the bottom wall of the external shell 1. A rotating assembly is built into the bottom side of the external shell 1, which is connected to the bottom of the connecting rod 7 and is used to drive the connecting rod 7 to rotate. Two brush plates 10 are fixedly connected to the outside of the connecting rod 7, which are in contact with the bottom of the filter mesh gasket 4 and the filter sponge 5;

[0027] Specifically, water can be introduced from the opening of the exchange column top cover 3. The water flows downward and passes through the filter mesh gasket 4 and the filter sponge 5 in sequence. At the same time, the rotating assembly at the bottom of the external shell 1 is operated to drive the connecting rod 7 to rotate. The connecting rod 7 drives the brush plate 10 to rotate on the outer surface while rotating. When the water flows downward to backwash the filter mesh gasket 4 and the filter sponge 5, the impurities accumulated on the surface of the filter mesh gasket 4 and the filter sponge 5 can be better cleaned under the rotation of the brush plate 10, so as to greatly reduce the problem of impurities accumulating on the surface of the filter mesh gasket 4 and the filter sponge 5 and causing the filtering effect to decrease, which is conducive to ensuring the normal operation of the socket-type isobaric liquid-inlet resin exchange column.

[0028] Reference Figure 2 , Figure 3 and Figure 7 The rotating assembly includes a connecting column 8, a square rod 14 and a rotating disk 9. The connecting column 8 is rotatably connected to the inside of the external shell 1. The square rod 14 is fixedly connected to the bottom of the connecting rod 7, and the rotating disk 9 is fixed to the bottom of the connecting column 8. A square groove is provided inside the top side of the connecting column 8. The square groove cooperates with the square rod 14 so that the bottom of the square rod 14 can smoothly extend into the square groove to ensure a stable connection between the two. Specifically, when the ion exchange column 2 is installed inside the external shell 1, the square rod 14 at the bottom of the connecting rod 7 cooperates with the square groove inside the connecting column 8, and the connecting column 8 can be driven to rotate by the rotating disk 9 to realize the rotation operation of the connecting rod 7. The movable connection between the bottom of the connecting rod 7 and the external shell 1 is conducive to the separation of the ion exchange column 2 and the external shell 1.

[0029] Reference Figure 4 and Figure 6A connecting sleeve 13 is fixed to the bottom of the fixed rod 6, and the top of the connecting rod 7 is inserted into the inside of the connecting sleeve 13 to achieve rotational connection with its inner wall. Specifically, the connecting rod 7 is movably connected to the fixed rod 6 through the connecting sleeve 13, which is convenient for separating the fixed rod 6 and the connecting rod 7 when disassembling the exchange column top cover 3, so as to facilitate the disassembly of the exchange column top cover 3 and the ion exchange column 2.

[0030] Reference Figure 4 and Figure 6 A brush plate 10 is also fixed on the outside of the connecting rod 7 and above the filter mesh gasket 4 and the filter sponge 5. Specifically, the brush plate 10 located above can brush the upper surface of the filter mesh gasket 4 and the filter sponge 5 under the action of the connecting rod 7 to ensure the cleaning quality above the filter mesh gasket 4 and the filter sponge 5.

[0031] Reference Figure 1 and Figure 2 The bottom of the outer shell 1 is fixedly connected with three supporting legs 12 in an equidistant and symmetrical manner to enhance the stability of the overall structure and separate the turntable 9 and the drain port 11 from the ground.

[0032] Reference Figure 2 Figure 3 A liquid discharge port 11 is also provided at the bottom of the outer shell 1, which is located on one side of the connecting column 8, so as to facilitate the discharge of liquid and the discharge of sewage after cleaning.

[0033] Working principle: water is introduced from the opening of the exchange column top cover 3. The water flows downward and passes through the filter mesh gasket 4 and the filter sponge 5 in turn. At the same time, the rotating assembly at the bottom of the external shell 1 is operated to drive the connecting rod 7 to rotate. The connecting rod 7 rotates and drives the brush plate 10 to rotate on the outer surface. When the water flows downward to backwash the filter mesh gasket 4 and the filter sponge 5, the impurities accumulated on the surface of the filter mesh gasket 4 and the filter sponge 5 can be better cleaned under the rotation of the brush plate 10, so as to greatly reduce the problem of impurities accumulating on the surface of the filter mesh gasket 4 and the filter sponge 5 and causing the filtering effect to decrease, which is conducive to ensuring the normal operation of the socket-type isobaric liquid-inlet resin exchange column.

[0034] The embodiments of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the technical field without departing from the purpose of the present invention.
