[0011] Preferably, the winding plate is wound with a pull rope outside, and the length of the pull rope is greater than the height of the filter assembly.

[0012] Compared with the prior art, the utility model has the beneficial effects that:

[0013] 1. The utility model discloses a winding plate and a pull rope, and the winding plate rotates to wind the pull rope, and the pull rope pulls the air inlet pipe outlet to move, so that the position of the air inlet pipe outlet changes, dirt adsorbed on the surface of the filter assembly can be blown to the bottom of the tank body, the cleaning area is increased, and the cleaning effect is improved.

[0014] 2. The utility model discloses a torsion spring, which is installed between the support and the winding plate, and the elastic force of the torsion spring makes the winding plate rotate reversely, so that the position of the outlet can be automatically restored, and the winding plate does not need to be reversely rotated again, thereby reducing the operation steps of the staff.

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0021] Please refer to Figures 1-4 The utility model provides the following technical scheme:

[0022] A plate-and-frame filter comprises a tank body 1 and a filter assembly 2, the filter assembly 2 is located inside the tank body 1, an air inlet pipe 4 is installed on the tank body 1, a plurality of air outlets are arranged on the air inlet pipe 4, and the end of the air outlet faces the filter assembly 2; the filter assembly 2 is composed of a filter plate, a paper plate and a filter frame, and the side edge of the filter assembly 2 is attached to the inner wall of the tank body 1.

[0023] The filter channel is punched into the inside of the tank body 1, the filtrate passes through the filter plate on the filter frame, and the solid is intercepted on the filter plate to form a filter cake, thereby realizing the filtering function,

[0024] The inside of the tank body 1 is provided with a support column 3, and the mounting rod 6 is fixed on the support column 3.

[0025] The air inlet pipe 4 is provided with a pull rope 7, the air inlet pipe 4 is a hose, the support column 3 is rotationally connected with a winding plate 5 at equal intervals, a torsion spring 8 is arranged between the winding plate 5 and the support column 3, the pull rope 7 is wound on the outer side of the winding plate 5, and the length of the pull rope 7 is greater than the height of the filter assembly 2.

[0026] When the filter cake fills the inside of the tank body 1, the gas enters the inside of the tank body 1 through the air inlet pipe 4, the gas comes out from the air outlet position of the air inlet pipe 4, then the winding plate 5 is forwardly rotated (which can be manually or electrically), the winding plate 5 is forwardly rotated to wind the pull rope 7, the pull rope 7 is wound to pull the air outlet of the air inlet pipe 4, so that the air outlet of the air inlet pipe 4 moves upward, thereby the gas can blow the filter cake accumulated on the surface of the filter assembly 2, and the forward rotation of the winding plate 5 causes the torsion spring 8 to be twisted or rotationally deformed, thereby storing energy to realize force accumulation.

[0027] When the air outlet of the air inlet pipe 4 moves to the uppermost position and releases the winding plate 5, the winding plate 5 no longer rotates, after the external force is removed, the torsion spring 8 returns to the original state, releases the stored energy to reversely rotate the winding plate 5, the force accumulation of the torsion spring 8 and the gravity of the air outlet position of the air inlet pipe 4 move downward, so that the gas generated by the air outlet of the air inlet pipe 4 covers the surface of the filter assembly 2, thereby improving the cleaning effect.

[0028] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace part of the technical features, any modification, equivalent replacement, improvement, etc. within the spirit and principles of the utility model should be included in the protection scope of the utility model.
