[0023] Embodiment 1

[0024] Please refer to the attached drawings. The utility model provides a technical solution: a drilling fluid production filtering device, comprising a filter box 1, partitions 101 are symmetrically fixed on both sides of the bottom surface of the filter box 1, and a filter tank is set between the two partitions 101, and a waste tank is set outside the partition 101, and a water outlet pipe 103 is fixed in the middle of the bottom of the filter tank, and a collection tank 104 is slidably connected in the waste tank.

[0025] An arc-shaped filter screen 105 is fixed between the top ends of the two partitions 101, and a delivery pipe 106 is fixed at the center of the filter screen 105 in the filter box 1. A plurality of water outlets are evenly arranged at the bottom of the delivery pipe 106 along its length direction, and a water inlet pipe 109 is connected to the center of one end of the delivery pipe 106. A scraper plate 2 is provided on the outer side of the delivery pipe 106 along the radial direction, the outer end of the scraper plate 2 is in contact with the filter screen 105, and a rotating component is connected to the inner end, and two pushing components are symmetrically arranged on both sides of the scraper plate 2.

[0026] When it is necessary to filter the drilling fluid, the liquid is transported to the delivery pipe 106 through the water inlet pipe 109 and discharged to the filter screen 105 through the water outlet. The liquid is filtered by the filter screen 105, and the filtered solid particles or waste are accumulated on the filter screen 105. When it is necessary to clean the filter screen 105, the scraper plate 2 is rotated from one side of the filter screen 105 to the other side through the rotating component, and the waste on the filter screen 105 is moved through the bottom end of the scraper plate 2 to clean the waste on the filter screen 105 to avoid clogging of the filter screen 105 and affecting subsequent filtration, and the waste is moved to the top of the partition 101, and then the waste on the scraper plate 2 is moved outward by the pushing component and falls into the collecting tank 104, and drained through the mesh holes at the bottom of the collecting tank 104. When the drainage is completed, the collecting tank 104 can be slid outward and taken out, making the collection and treatment of waste simpler and more convenient.

[0027] Among them, the rotating assembly includes two rotating rods 202 symmetrically fixed to the inner end of the scraper plate 2, a rotating ring plate 206 is fixed to one end of the rotating rod 202 close to the conveying pipe 106, and the rotating ring plate 206 is rotatably connected to the outer side of the conveying pipe 106, and a plurality of teeth are evenly fixed on the rotating ring plate 206 along the circumferential direction, and a first gear 107 is meshed with the upper teeth, and the first gear 107 is rotatably connected to the side wall of the filter box 1 and is connected to a motor.

[0028] When the scraper plate 2 needs to be rotated, the first gear 107 is started to make the rotating ring plate 206 drive the rotating rod 202 to rotate, thereby rotating the scraper plate 2 so that the scraper plate 2 can be rotated from one side of the filter screen 105 to the other side to clean the hanging materials.

[0029] Among them, the pushing assembly includes a pushing rod 205 slidably connected to the scraper plate 2, a sliding rod 204 is fixed on the pushing rod 205 at a position corresponding to the rotating rod 202, a sliding rail 203 is correspondingly provided on the rotating rod 202, and the sliding rod 204 is slidably connected to the sliding rail 203, and a plurality of teeth are evenly fixed on the sliding rod 204 along the length direction, and the second gear 108 is rotatably connected at the obliquely lower positions on both sides of the inner cavity side wall of the filter box 1 corresponding to the first gear 107, the second gear 108 is connected to the motor, and the sliding rod 204 is connected to the second gear 108 on the corresponding side through the teeth, and pressure blocks 207 are symmetrically provided on the two side walls of the sliding rail 203, one end of the pressure block 207 extends out of the sliding rail 203, and is fixed with a pressure plate 208, and the inner side surface of the pressure plate 208 is in contact with the outer side wall of the sliding rail 203 through a plurality of evenly arranged springs.

[0030] When the rotating assembly drives the scraper plate 2 to rotate at the top of the partition 101 on the corresponding side, the teeth on the slide bar 204 mesh with the second gear 108 on the corresponding side, and the motor is started to rotate the second gear 108, so that the slide bar 204 moves in the slide rail 203, and pushes the push rod 205 outward, thereby pushing the waste on the scraper plate 2 outward through the push rod 205 so that the waste falls into the collecting trough 104. After pushing the material, the second gear 108 reverses, and the slide bar 204 drives the push rod 205 back to its position, wherein the spring on the pressure plate 208 is always in a stretched state, and under the action of the spring, the pressure block 207 is pressed tightly on both sides of the slide bar 204, which plays a positioning role for the slide bar 204, so that after the slide bar 204 is separated from the second gear 108 and during the rotation of the scraper plate 2, the slide bar 204 will not move freely relative to the slide rail 203.

[0031] Among them, the first friction pads are symmetrically fixed on both sides of the slide bar 204, and the second friction pad is fixed on the inner end of the pressure block 207. The second friction pad contacts the first friction pad to increase the friction between the slide bar 204 and the pressure block 207, thereby improving the positioning effect of the slide bar 204.
