[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging it into a certain water body or reusing it; sewage treatment is widely used in various fields such as construction, agriculture, transportation, energy, petrochemical, environmental protection, urban landscape, medical treatment, and catering, and is also increasingly entering the daily lives of ordinary people;

[0003] There are various methods for sewage treatment. Among them, filtering sewage and then performing low-temperature evaporation is the most commonly used sewage treatment method. When a low-temperature evaporator is working, a filtration device is used at the rear end of the low-temperature evaporator. However, there are certain deficiencies in the current filtration device during use. For example, the end cover on the filtration device is relatively heavy. When it is necessary to replace the filter element body inside the filtration device, the end cover needs to be removed and placed down, and then reinstalled after the replacement of the filter element body is completed. This is rather troublesome during operation and lacks practicality. Summary of the Utility Model

[0022] The following further elaborates on this application in conjunction with the attached Figures 1 - 3 drawings.

[0023] The embodiment of this application discloses a filtration device at the rear end of a low-temperature evaporator, which includes a filtration housing 1. A fixed seat 3 is arranged on the outer wall of the filtration housing 1 near the port. A rotator 4 is fixedly installed on the top of the fixed seat 3. The top of the rotator 4 is fixedly installed with a support rod 5. The screw hole opened on the support rod 5 is adaptively installed with a tightening bolt 7. One end of the tightening bolt 7 is installed with a bearing seat installed on the top of a cover plate 6. When it is necessary to open the cover plate 6 to maintain the inside of the filtration housing 1, turn the handle on the cover plate 6 so that the limit block 10 comes out of the limit card slot on the top of the filtration housing 1. Then turn the tightening bolt 7 so that the cover plate 6 slowly moves upward. After the cover plate 6 is removed from the top end of the filtration housing 1, the rotator 4 can be rotated so that the cover plate 6 slowly moves to one side. In this way, the installation of the cover plate 6 in the later stage is also relatively convenient, improving the practicality.

[0024] Refer to Figure 1 , a plurality of limit blocks 10 are fixedly installed at the bottom of the cover plate 6. The limit blocks 10 are adapted to the limit card slots opened on the top of the filtration housing 1. The opening opened on the outer wall of the filtration housing 1 near the top end is adaptively installed with a feed pipe 8. The opening opened on the outer wall of the filtration housing 1 near the bottom end is installed with a discharge pipe 9.

[0025] Refer to Figure 1 and Figure 3, a filter mesh plate 11 is arranged inside the filter housing 1 near the water inlet pipe opening to preliminarily filter the water entering the filter housing 1.

[0026] Refer to Figure 1 and Figure 3 , a first support plate 12 is arranged below the filter mesh plate 11 inside the filter housing 1, and a second support plate 13 is arranged near the bottom inside the filter housing 1.

[0027] Refer to Figure 1 and Figure 3 , a plurality of filter elements 15 are also arranged between the first support plate 12 and the second support plate 13. The bottom end of the filter element 15 passes through the corresponding through holes opened on the second support plate 13 and is adaptively installed with a threaded stud 14 arranged at the bottom of the filter housing 1. A sealing block arranged near the bottom of the filter element 15 is in contact with the top surface of the second support plate 13.

[0028] Refer to Figure 1 , the top water inlet of the filter element 15 is placed at the through hole opened on the first support plate 12, and the top water inlet of the filter element 15 is also sealed and fixed with the through hole at the first support plate 12.

[0029] The implementation principle of the low-temperature evaporator rear-end filtering device in the embodiment of the present application is as follows: during use, water enters the filter housing 1 through the water inlet pipe 8. The filter mesh plate 11 inside the filter housing 1 preliminarily filters the water, and after filtering, it flows into the corresponding filter element 15. The filter element 15 filters the preliminarily filtered water again. When it is necessary to open the cover plate 6 to maintain the inside of the filter housing 1, turn the handle on the cover plate 6 so that the limit catch 10 comes out of the limit card slot on the top of the filter housing 1, and then turn the tightening bolt 7 so that the cover plate 6 slowly moves upward. After the cover plate 6 is removed from the top of the filter housing 1, the rotator 4 can be rotated so that the cover plate 6 slowly moves to one side, which makes the later installation of the cover plate 6 more convenient and improves the practicability.

[0030] The above are all the preferred embodiments of the present application. The protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of the present application should be covered within the protection scope of the present application.
