[0002] Water reducer is a concrete admixture that can reduce the amount of mixing water while maintaining the slump of concrete. Most of them are anionic surfactants, such as lignin sulfonate, naphthalene sulfonate formaldehyde polymer, etc. After being added to the concrete mixture, it has a dispersing effect on cement particles, can improve its workability, reduce the unit water consumption, improve the fluidity of the concrete mixture, or reduce the unit cement consumption.

Flanges are installed on the docking surfaces of the tank bottom 6-2 and the tank middle 6-3, and on the docking surfaces of the tank middle 6-3 and the tank upper 6-4, and are detachably connected by bolts and locking nuts passing through the flanges; similarly, a flange is provided on the upper part of the tank upper 6-4, and is detachably connected to the filter tank cover 6-5 by bolts and locking nuts passing through the flanges. Through the above arrangement, the tank structure can be easily disassembled and installed, and the structural components in the tank structure can be easily disassembled and installed and routinely maintained.

[0023] In addition, if Figure 1 As shown, the first liquid inlet 11 and the first liquid outlet 14 connected to the inner cavity are respectively installed on the outer peripheral walls of the upper part 6-4 and the middle part 6-3 of the first tank structure 6, and the second liquid inlet 13 and the second liquid outlet 15 connected to the inner cavity are respectively installed on the outer peripheral walls of the upper part and the middle part of the tank in the second tank structure 17. A feed tee 10 and a liquid valve 9 are installed between the first liquid inlet 11 and the second liquid inlet 13, and a discharge tee 12 and a liquid valve 9 are installed between the first liquid outlet 14 and the second liquid outlet 15. Through the above settings, the first tank structure 6 and the second tank structure 17 can be selected to run the filtering operation at the same time according to actual work needs, or the first tank structure 6 and the second tank structure 17 can be selected to perform the filtering operation.

[0024] like Figure 1 As shown, this embodiment further includes a first waste liquid outlet 4 installed at the bottom of the first tank structure 6 and a second waste liquid outlet 18 installed at the bottom of the second tank structure 17. Solenoid valves are installed on the first waste liquid outlet 4 and the second waste liquid outlet 18.

[0025] like Figure 1 As shown, the present embodiment further includes a filter mounting structure 5 fixedly connected to the inner walls of the first tank structure 6 and the second tank structure 17, and a filter cylinder 7 is mounted on the filter mounting structure 5. The filter cylinder 7 is made of stainless steel; in order to facilitate disassembly and installation, the filter cylinder 7 can be detachably mounted on the filter mounting structure 5.

[0028] In the actual working process, the water reducer flows into the inner cavity of the filter cylinder 7 in the tank structure through the liquid inlet, and flows into the inner cavity of the filter cylinder 7 under the action of its own gravity, and flows to the liquid outlet through the filter cylinder 7. During this process, the filter cylinder 7 can filter the water reducer flowing through, so that impurities in the water reducer mother liquor remain on the inner wall of the filter cylinder 7, thereby realizing the filtering operation.

[0029] In order to clean the filter cartridge 7, the present embodiment further comprises a first cleaning assembly 8 and a second cleaning assembly 16, which are used to wash and clean the filter cartridge 7 to prevent the mesh on the filter cartridge 7 from being clogged and affecting the normal filtering operation of the purification device. In the present embodiment, the first cleaning assembly 8 and the second cleaning assembly 16 have the same structure.

In order to ensure that the brush body 8-1-5 is always in tight contact with the inner wall of the filter cylinder 7 to achieve the cleaning operation, the cleaning brush assembly 8-1 also includes a spring retaining ring 8-1-2 installed on the outer peripheral wall of the telescopic sleeve 8-1-3, and also includes a buffer spring 8-1-4 inserted on the telescopic sleeve 8-1-3 and located between the spring retaining ring 8-1-2 and the telescopic mounting member 8-1-1.

[0032] In this embodiment, the structure of the second cleaning component 16 is consistent with the structure of the first cleaning component 8 .

[0033] Working process:

[0034] The water reducer mother liquid flows into the inner cavity of the filter cylinder 7 in the tank structure through the feed tee 10 and the liquid inlet, and the water reducer mother liquid flows into the inner cavity of the filter cylinder 7 and flows to the liquid outlet through the filter cylinder 7. In this process, the filter cylinder 7 can filter the water reducer flowing through, so that impurities in the water reducer mother liquid remain on the inner wall of the filter cylinder 7, thereby realizing the filtering operation; the water reducer mother liquid that has completed the filtering operation flows out of the purification device through the liquid outlet and the discharge tee 12 for collection;

[0035] After working for a period of time, first close the liquid valve 9 installed on the first liquid inlet 11 and the first liquid outlet 14, so that the first tank structure 6 stops filtering and performs cleaning operation, and the second tank structure 17 continues filtering operation at this time; then start the rotary drive member 8-7 in the first cleaning assembly 8 to drive the lower shaft 8-2 to rotate, so that the cleaning brush assembly 8-1 can clean the inner wall of the filter cylinder 7. After completing the cleaning operation of the filter cylinder 7 in the first tank structure 6, open the solenoid valve installed on the first waste liquid outlet 4 to discharge the cleaning waste liquid in the first tank structure 6, and then open the liquid valve 9 installed on the first liquid inlet 11 and the first liquid outlet 14 to restart the filtering operation of the first tank structure 6;

[0036] After the cleaning operation of the filter cylinder 7 in the first tank structure 6 is completed, the liquid valve 9 installed on the second liquid inlet 13 and the second liquid outlet 15 is closed, and the first liquid inlet 11 and the first liquid outlet 14 are opened; then the second cleaning component 16 is started to clean the filter cylinder 7 in the second tank structure 17. After the cleaning operation of the filter cylinder 7 in the second tank structure 17 is completed, the solenoid valve installed on the second waste liquid outlet 18 is opened to discharge the cleaning waste liquid in the second tank structure 17, and then the liquid valve 9 installed on the second liquid inlet 13 and the second liquid outlet 15 is opened. After the cleaning operation of the filter cylinder 7 in the second tank structure 17 is completed, the first tank structure 6 and the second tank structure 17 can perform filtering operations at the same time.

[0037] The utility model can automatically clean the filter screen cylinder 7, thereby solving the problem that when the filter screen is clogged, it needs to be manually disassembled and taken out for cleaning. At the same time, when cleaning the filter screen cylinder 7, there is no need to stop the filtering operation of the water reducing agent mother liquid, thereby improving the working efficiency.
