Description

Technical Field

[0001] The utility model relates to the technical field of filter pressing, in particular to a plate frame cleaning device. Background Art

[0002] The plate and frame filter press can filter the sludge obtained in sewage treatment. The plate and frame filter plate used needs to be cleaned after multiple filtrations, and the current cleaning method is to directly flush the filter plate with a high-pressure water gun. This cleaning method is not convenient for collecting and treating the flushed sewage, and the sludge in the cleaning water is also likely to cause blockage of the conveying pipeline. Second, during the flushing process, the sludge splashes out, which is easy to pollute the cleaning environment and also easy to cause harm to the operator. Utility Model Content

[0003] The utility model provides a plate frame cleaning device to solve the above-mentioned deficiencies of the prior art, facilitate the cleaning operation of the plate frame filter plate, and reduce the pollution caused to the environment, and has strong practicality.

[0004] In order to achieve the purpose of this utility model, the following technologies are proposed:

When the cleaning box is used to wash the plate frame, a protective box is provided to facilitate the treatment of the sewage obtained, and at the same time, the splashing of the cleaning water can be avoided, thereby improving the safety during cleaning. The cleaning water can be sprayed out at high pressure through the provided nozzle, so as to wash the filter plate.

[0006] An upper cylinder is installed inside the cleaning box. An upper strip is rotatably provided at the upper end of the upper cylinder. Two pairs of guide holes are opened at both ends of the upper strip. A through rod is passed through the guide hole. A side plate is provided at the lower end of each pair of through rods at the same end. A lower card plate is provided at the lower end of each pair of through rods at the same end. An inner push plate is provided at the upper end of each pair of through rods at the same end. An inclined surface is formed on the outer wall of the inner push plate. The upper end of the inclined surface extends inwardly. A U-shaped groove is formed at the upper end of the inner push plate. A connecting rod is provided in the U-shaped groove. An inner push rod is provided at the outer end of the connecting rod. The outer periphery of the inner push rod is tangent to the inclined surface. A movable upper plate is provided at the inner end of the connecting rod. Through the provided side plates, the inner push plate can position and clamp the two sides of the filter plate through its inner wall when the inner push plate moves. When the provided inner push rod is lifted and lowered, the inner push plate and the side plate can be moved, thereby achieving the purpose of limiting the side plate. The provided lower card plate can limit the lower end of the filter plate, thereby improving the safety of the filter plate when flushing.

[0007] A vertical rod is provided on the cleaning box, and the vertical rod passes through the upper plate bar. When driving the filter plate to move downward, it guides the movement of the filter plate. When placing the filter plate, the upper plate bar can be rotated to one side first. When the filter plate is fixed, the side plate can be located at the upper end of the rectangular hole. In this way, the stability of the filter plate when moving downward is ensured.

[0008] Furthermore, a pair of filter plates are provided at the lower end of the cleaning box, an inclined plate is provided at the inner end of the filter plate, the inner end of the inclined plate extends upwardly, and an upper plate is provided at the upper end of the inclined plate. The flushing water is filtered through the filter plate to prevent sludge from directly entering the drainage system.

[0009] Furthermore, a plurality of blocking rods are formed on the upper plate to block the lumpy sludge so as to prevent the sludge from moving onto the filter plate.

[0010] Furthermore, side clamping plates are respectively provided on both sides of the side plate to prevent the filter plate from tilting during the flushing process.

[0011] Furthermore, a pair of circular sleeves are provided on the movable upper plate, and a spring is provided in the circular sleeve. The spring is located on the upper side of the upper plate strip. A guide vertical rod is passed through the circular sleeve, and the guide vertical rod is arranged on the upper plate strip. An end plate is provided at the upper end of the guide vertical rod, and a rotating recess is provided on the upper plate strip. A rotating arm is rotatably provided on the upper end of the rotating recess, and a pressure wheel is rotatably provided on the rotating arm. The outer periphery of the pressure wheel is tangent to the upper wall of the movable upper plate, and a groove is opened on the movable plate. The rotating arm passes through the groove. The guide vertical rod guides the movable upper plate, and the pressure wheel, when acting on the movable upper plate, can make the movable upper plate move downward, thereby acting on the inclined surface through the inner push rod, and then limiting the filter plate through the side plate, and at the same time ensuring the stability of the filter plate after being fixed.

[0012] Furthermore, a pair of right-angled trapezoidal plates are provided on the upper wall of the movable middle plate, and the inner walls of the right-angled trapezoidal plates are inclined surfaces. The pressure wheel can be limited by the provided right-angled trapezoidal plates, thereby ensuring the fixing effect of the filter plate.

[0013] The advantages of the above technical solution are:

[0014] The utility model is convenient for cleaning the filter plate, can preliminarily treat the cleaning water during cleaning, and can also prevent the cleaning water from splashing, thereby preventing pollution to the environment during cleaning. BRIEF DESCRIPTION OF THE DRAWINGS
