[0020] The following will clearly and completely describe the present utility model in conjunction with the drawings and embodiments:

[0021] As Figures 1 to 4As shown in the figure, a filtering device for peanut oil pressing of the present utility model includes an installation sleeve 1. A fixing member is provided at the top of the installation sleeve 1. The filtering device can be installed on the drain pipe of the oil pressing equipment through fixation. Specifically, the fixing member includes an arc-shaped fixing plate 2. A fixing screw 3 is threadedly arranged on the installation sleeve 1. The fixing screw 3 is rotatably connected to the installation sleeve 1. By rotating the fixing screw 3, the two fixing plates 2 can be clamped outside the drain pipe to realize the fixed connection between the device and the drain pipe. A diversion cylinder 4 is conductively connected to the bottom of the installation sleeve 1. The diversion cylinder 4 is arranged to be through up and down, and a filter screen 5 is arranged inside it. The filter screen 5 is rotatably arranged in the diversion cylinder 4 through a rotating shaft 6. One of the rotating shafts 6 penetrates to the outside of the diversion cylinder 4, so that by rotating the rotating shaft 6, the filter screen 5 can be driven to flip in the diversion cylinder 4, thus completing the cleaning operation of the filter residue. There is no need to disassemble the whole device, and the operation is simple and fast, with strong practicability.

[0022] Furthermore, in this embodiment, the filter screen 5 is a concave arc-shaped structure to increase the filtering area, ensure the filtering efficiency, and at the same time extend the cleaning time of the filter screen 5 and the cleaning frequency. In addition, sealing rings 7 are arranged on the inner wall of the diversion cylinder 4 and the outside of the filter screen 5. The sealing rings 7 are made of rubber material. In the initial state, the sealing ring 7 on the inner wall of the diversion cylinder 4 is in close contact with the sealing ring 7 on the outside of the filter screen 5 to achieve sealing.

[0023] Furthermore, a positioning member for positioning the filter screen 5 is arranged on the diversion cylinder 4 to ensure the stability of the filter screen 5 during the working process. Specifically, the positioning member includes a positioning rod 8. The positioning rod 8 can only be adjusted to move radially along the diversion cylinder 4 to move in the direction close to or away from the rotating shaft 6. A cross-shaped positioning head is arranged at the end of the positioning rod 8. A cross-shaped positioning hole is arranged at the end of the rotating shaft 6 that does not penetrate out of the diversion cylinder 4. The positioning operation of the filter screen 5 can be realized by inserting the positioning head into the positioning hole. In addition, the positioning rod 8 is preferably elastically connected to the diversion cylinder 4 to facilitate the automatic reset of the positioning rod 8. In this embodiment, an adjustment hole 9 is opened on the diversion cylinder 4. The positioning rod 8 slides in the adjustment hole 9. Guide grooves 10 are arranged at the upper and lower ends of the adjustment hole 9. Guide blocks 11 that slide in the guide grooves 10 are arranged on the positioning rod 8. The positioning rod 8 is elastically arranged in the positioning groove through a positioning spring 12.

[0024] Furthermore, the guide tube 4 includes a fixed sleeve 4-1 fixedly connected to the mounting sleeve 1 at the upper part, and a movable sleeve 4-2 elastically arranged at the bottom of the fixed sleeve 4-1. In the initial state, the movable sleeve 4-2 is in close contact with the guide tube 4; the filter screen 5 is arranged in the movable sleeve 4-2. Specifically, a limit block 13 is arranged at the bottom of the fixed sleeve 4-1, and the limit block 13 is arranged in a limit groove 15 opened at the top of the movable sleeve 4-2 through a limit spring 14; the optimized arrangement of the guide tube 4 facilitates the separation of the filter screen 5 from the fixed sleeve 4-1 by pulling the movable sleeve 4-2 after turning over the filter screen 5, and uses the restoring force of the limit spring 14 to drive the movable sleeve 4-2 to collide with the fixed sleeve 4-1 to achieve the rapid drop of the filter residue in the filter screen 5, which provides convenience for cleaning the filter residue.

[0025] Furthermore, in this embodiment, the rotating shaft 6 is connected to the guide tube 4 through a bearing to reduce the friction between the rotating shaft 6 and the guide tube 4. In addition, a rubber sleeve 16 is arranged in the mounting sleeve 1, and the rubber sleeve 16 is in an inverted truncated cone shape. The optimized arrangement of the rubber sleeve 16 facilitates the tight connection between the mounting sleeve 1 and the oil drain pipe, wherein the opening size of the bottom end of the rubber sleeve 16 is not larger than the opening size of the guide tube 4, so that the oil can smoothly enter the guide tube 4.

[0026] When the utility model is in use, the mounting sleeve 1 is mounted on the oil drain pipe by means of a fixing piece so as to perform filtering operation. When the filter screen 5 needs to be cleaned, the positioning rod 8 can be pulled out to make the positioning head disengage from the positioning hole. Then, the rotating shaft 6 located outside the guide cylinder 4 is rotated to drive the filter screen 5 to flip over so as to discharge the filter residue received in the filter screen 5. Finally, the movable section of the guide cylinder 4 can be pulled up and down, and the restoring force of the limit spring 14 can be used to realize the collision between the movable section and the fixed section, so that the filter screen 5 vibrates, and the residue attached to the filter screen 5 is vibrated and falls off, thereby further improving the convenience of cleaning the filter residue.
