An agricultural pond is a structure for storing agricultural water. When a pond is used to store water, there are many debris in the water. When it is used, the water needs to be filtered. The laminated filter is a common filtering equipment in agricultural water.

[0003] The laminated filter is composed of a large number of thin annular laminates overlapped and locked to form a cylindrical filter element. Each annular laminate has two sides, and many filter grooves are distributed on both sides. It can work accurately and stably under quite harsh conditions of use and rarely requires maintenance. It is widely used in irrigation, sewage regeneration, municipal water supply, water plants and other fields.

[0004] When using a laminated filter to filter pool water, the filter mechanism inside the laminated filter is in a static state, and the filtered debris adheres to the filter mechanism. The positions of the debris and the filter mechanism are relatively fixed. When the amount of filtered debris increases, the debris will cover the filter element of the filter mechanism, thereby reducing the filtering speed of the raw water. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Example 1: Reference Figure 1-4 A laminated filter for an agricultural water pool comprises a housing 1, a sealing cover 2 is detachably connected to the upper end of the housing 1, a water inlet pipe is connected to the upper end of the sealing cover 2, a drain pipe is connected to the bottom end of the housing 1, an elastic puller 3 is rotatably connected to the bottom end of the sealing cover 2, a laminated filter mechanism 4 is rotatably connected to the elastic puller 3, and the laminated filter mechanism 4 cooperates with the housing 1;

[0024] The elastic puller 3 includes a first connecting rod 31, one end of which is rotatably connected to the bottom end of the sealing cover 2, and the other end of the first connecting rod 31 is provided with a groove 33, an anti-corrosion layer is sprayed in the groove 33, a second connecting rod 32 is slidably connected to the groove 33, one end of the second connecting rod 32 is rotatably connected to the laminated filter mechanism 4, a spring 34 is fixedly connected in the groove 33, and one end of the spring 34 is fixedly connected to the second connecting rod 32.

[0025] Working process: raw water is introduced into the shell 1 through the water inlet pipe, and the introduced raw water falls on the laminated filter mechanism 4. The weight of the laminated filter mechanism 4 increases, and the laminated filter mechanism 4 pulls the second connecting rod 32 downward. The second connecting rod 32 pulls the spring 34. The spring 34 is pulled to generate a spring. The laminated filter mechanism 4 moves to a certain extent in the vertical direction under the impact of the water flow and the action of the spring 34, so that the laminated filter mechanism 4 is in a moving state. The raw water falls on the bottom end of the shell 1 after being filtered by the laminated filter mechanism 4. The filtered water at the bottom end of the shell 1 is discharged from the drain pipe. During the filtering process of the raw water by the laminated filter mechanism 4 in the moving state, the filtered impurities move on the laminated filter mechanism 4, and the impurities move relative to the laminated filter mechanism 4, so that the laminated filter mechanism 4 maintains the filtering effect on the raw water and does not reduce the filtering speed of the raw water.

[0026] Example 2: In Example 1, during the filtering process of the raw water by the laminated filter mechanism 4, the filtered impurities are scattered on the laminated filter mechanism 4, which is not conducive to the filtering of the raw water by the laminated filter mechanism 4. Figure 3As another preferred embodiment of the utility model, the difference from the embodiment 1 is that the laminated filter mechanism 4 includes a fixed column 41, the fixed column 41 is rotatably connected to the second connecting rod 32, and a plurality of first fixed rings 42 are connected to the fixed column 41 at equal intervals along the length direction, and each first fixed ring 42 is fixedly connected to a filter plate 43, and the filter plate 43 is arranged upwardly inclined toward the fixed column 41, and the bottom end of each filter plate 43 is fixedly connected to a second fixed ring 44, and the second fixed ring 44 cooperates with the housing 1. After the raw water is introduced The filter plate 43 is impacted, and the filter plate 43 drives the fixed column 41 to move through the first fixed ring 42. After the fixed column 41 moves, it pulls the second connecting rod 32. After the raw water contacts the filter plate 43, the filter plate 43 filters the raw water. Since the filter plate 43 moves in the vertical direction, the filtered debris moves at the upper end of the filter plate 43. Since the filter plate 43 is inclined upward toward the fixed column 41, the filtered debris moves toward the second fixed ring 44 and will not remain at the upper end of the filter plate 43, which is convenient for filtering the raw water.

[0027] Embodiment 3: In embodiment 2, since the filter plate 43 is tilted upward toward the fixing column 41, the filtered debris moves toward the second fixing ring 44, and the debris remains at the upper end of the second fixing ring 44. When the second fixing ring 44 moves in the vertical direction, the debris is easily moved to the upper end of the filter plate 43. Figure 5 As another preferred embodiment of the utility model, on the basis of embodiment 2, the upper end of each second fixing ring 44 is fixedly connected with a collecting mechanism 5, and the collecting mechanism 5 includes an open frame 51, and the open frame 51 is fixedly connected to the upper end of the second fixing ring 44, and the upper end of the open frame 51 is fixedly connected with a baffle 52, and the baffle 52 is inclined toward the inner wall direction of the open frame 51, and a collecting groove 53 is opened between the baffle 52 and the open frame 51, and the filtered debris moves toward the second fixing ring 44, and the debris enters the collecting groove 53, and the baffle 52 blocks the collecting groove 53. During the vertical movement of the second fixing ring 44, the debris is not easy to move to the upper end of the filter plate 43.

[0028] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
