DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-3 In this embodiment, a filtering and denitrification device that is easy to clean includes a fixed box 1, a collecting box 2 is fixedly installed at the bottom of the fixed box 1, a rotating assembly 7 is installed on the right side of the fixed box 1, a connecting tube 16 is plugged into the interior of the fixed box 1, a mounting plate 14 is fixedly installed on the left side of the connecting tube 16, a connecting pipe 17 is fixedly installed inside the connecting tube 16, a filter screen 8 is slidably installed between the connecting tube 16 and the connecting tube 17, and the connecting tube 16 is a semi-open cylindrical tube;

[0021] The rotating assembly 7 includes a driving motor 701, which is fixedly installed on the right side of the fixed box 1. A coupling 702 is installed on the output shaft of the driving motor 701. A rotating rod 703 is connected to the other end of the coupling 702. A cleaning rotating plate 704 is clamped on the outer surface of the rotating rod 703, and bristles 705 are arranged on the side of the cleaning rotating plate 704.

[0022] During specific implementation, by starting the driving motor 701, the output shaft of the driving motor 701 will drive the coupling 702 and the rotating rod 703 to rotate. When the rotating rod 703 rotates, it will synchronously drive the cleaning rotating plate 704 and the bristles 705 to rotate, thereby rotating on the surface of the conical filter 8 to clean and remove the dust on the surface of the filter 8.

[0023] Before the rotating component 7 rotates, the inlet and outlet of the first pipe 4 and the second pipe 5 are closed by the solenoid valve 6, and the electric telescopic rod 11 is started. The output shaft of the electric telescopic rod 11 will drive the connecting plate 12 and the sealing plate 9 to move to the left and right sides, and the dust falls into the collection box 2, where the dust is collected centrally. The cleaning efficiency of the filter screen 8 is improved by the rotating component 7.

[0024] By setting the rotating rod 703, when in use, the filter screen 8, the rotating rod 703, and the cleaning rotating plate 704 are quickly installed and combined by inserting the mounting plate 14 and the connecting tube 16 into the interior of the fixed box 1. The filter screen 8 passes through the connecting tube 17 and is slidably installed between the connecting tube 16 and the connecting tube 17. The cleaning rotating plate 704 is fixed to the outside of the rotating rod 703 by snap-fitting, thereby realizing the installation of the filter screen 8, the rotating rod 703, and the cleaning rotating plate 704.

[0025] The rotating rod 703 passes through the right side surface of the fixed box 1 and extends to the interior of the coupling 702, so that the rotating rod 703 is connected to the output shaft of the driving motor 701 through the coupling 702, so that the driving motor 701 can drive the rotating rod 703 and the cleaning rotating plate 704 to rotate for cleaning, and the installation and disassembly steps are relatively simple.

[0026] At the same time, the filter screen 8 is slidably mounted on the outside of the connecting pipe 17 and the inner wall of the connecting cylinder 16, so that the filter screen 8 can be easily disassembled and replaced.

[0027] The connecting plate 12 and the sealing plate 9 are driven to move by the electric telescopic rod 11, so that the filtered impurities can be cleaned when the filter screen 8 is cleaned. However, when it is not cleaned, the sealing plate 9 is arranged directly below the filter screen 8 and in direct contact with the filter screen 8, thereby avoiding air leakage and incomplete filtration caused by the filter screen 8 filtering out of stock air.

[0028] When implementing, follow these steps:

[0029] 1) First, quickly assemble the filter screen 8, the rotating rod 703, and the cleaning rotating plate 704 inside the connecting cylinder 16;

[0030] 2) Then the mounting plate 14 and the connecting tube 16 are inserted into the interior of the fixed box 1, and the rotating rod 703 is connected and fixed through the coupling 702;

[0031] 3) The output shaft of the electric telescopic rod 11 will drive the connecting plate 12 and the sealing plate 9 to move to the left and right sides;

[0032] 4) Finally, the rotating assembly 7 is started to clean the surface of the filter screen 8, and the generated filter-shaped impurities will directly fall into the interior of the collection box 2.

[0033] To sum up, the filtering and denitrification device which is easy to clean is provided with a rotating component 7. When in use, by starting the driving motor 701, the output shaft of the driving motor 701 will drive the coupling 702 and the rotating rod 703 to rotate. When the rotating rod 703 rotates, it will synchronously drive the cleaning rotating plate 704 and the bristles 705 to rotate, so as to rotate on the surface of the conical filter 8, so as to clean and drop the dust on the surface of the filter 8. By starting the electric telescopic rod 11, the output shaft of the electric telescopic rod 11 will drive the connecting plate 12 and the sealing plate 9 to move to the left and right sides, and the dust will fall into the collecting box 2, so that the dust will be collected in a centralized manner, and the cleaning efficiency of the filter 8 is improved by the rotating component 7.

[0034] In addition, by setting the rotating rod 703, when in use, the filter screen 8, the rotating rod 703, and the cleaning rotating plate 704 are quickly installed and combined by inserting the mounting plate 14 and the connecting tube 16 into the interior of the fixed box 1. The rotating rod 703 passes through the right side surface of the fixed box 1 and extends to the interior of the coupling 702, so that the rotating rod 703 is connected to the output shaft of the driving motor 701 through the coupling 702, so that the driving motor 701 can drive the rotating rod 703 and the cleaning rotating plate 704 to rotate and clean. The installation and disassembly steps are relatively simple. At the same time, the filter screen 8 is slidably installed on the outside of the connecting tube 17 and the inner wall of the connecting tube 16, so as to facilitate the disassembly and replacement of the filter screen 8.
