Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Embodiment 1

[0027] Please refer to the attached drawings. The utility model provides a technical solution: a drilling fluid recovery and treatment device with environmental protection effect, including a treatment box 1, a liquid inlet pipe 101 is symmetrically fixed on both sides of the top surface of the treatment box 1, a material discharge trough 105 is fixed in the middle of the inner cavity, and a plurality of parallel heat absorption pipes 3 are evenly arranged at the bottom, and both ends of the heat absorption pipe 3 extend out of the treatment box 1 and are externally connected to a cold water supply structure and a hot water recovery structure. A liquid outlet pipe 102 is arranged on one side of the bottom of the treatment box 1, and a valve is arranged in the liquid outlet pipe 102. The bottom of the material discharge trough 105 is symmetrically inclined on both sides, and the two sides of the material discharge trough 105 are symmetrically inclined. The ends extend out of the processing box 1, and filter plates 2 are symmetrically arranged on both sides of the top of the feed chute 105. Filter holes are evenly distributed on the filter plates 2 at the outside of the feed chute 105, and a rotating shaft 201 is fixed at the bottom inside the feed chute 105, and a vertical plate 403 is arranged on the top.

[0028] When the drilling fluid needs to be recovered, the drilling fluid is transported to the processing box 1 through the external device and the liquid inlet pipe 101, and filtered through the filter plate 2. During the filtering, the vertical plate 403 and the horizontal plate 402 play a water blocking role to prevent the drilling fluid from falling into the feed trough 105;

[0029] After the drilling fluid is filtered through the filter plate 2, it falls to the bottom of the processing box 1 and contacts the heat absorbing tube 3. Cold water is passed into the heat absorbing tube 3, and the heat in the drilling fluid is absorbed by the side wall of the heat absorbing tube 3, so that the heat is recycled and utilized to avoid heat waste.

[0030] When a large amount of impurities accumulate on the filter plate 2, the rotating assembly drives the moving shaft 401 and the vertical plate 403 to move upward, and drives the rotating shaft 201 and the filter plate 2 to rotate, so that the filter plate 2 is tilted toward the lower material trough 105, and the material on the filter plate 2 moves downward along the filter plate 2, enters the lower material trough 105, and gradually moves outward along the inclined bottom surface of the lower material trough 105, thereby cleaning and discharging the impurities on the filter plate 2.

[0031] Among them, the rotating assembly includes a first gear 202 fixed to the top of the rotating shaft 201, and a vertical rack 404 is provided on the outer side of the first gear 202, and the teeth on the rack 404 are located on the lower side section of the rack 404, and a movable plate 4 is provided above the processing box 1, and the tops of multiple movable shafts 401 are fixedly connected to the movable plate 4, and the tops of the racks 404 are also fixedly connected to the movable plate 4, and vertical hydraulic telescopic rods 405 are symmetrically connected to both sides of the bottom of the movable plate 4, and the bottom ends of the hydraulic telescopic rods 405 are fixedly connected to the upper part of the side wall of the processing box 1.

[0032] When it is necessary to clean the impurities on the filter plate 2, the movable plate 4 is moved upward by the hydraulic telescopic rod 405, and the horizontal plate 402 and the vertical plate 403 are moved upward by the moving shaft 401, so that the vertical plate 403 is separated from the filter plate 2, and then the movable plate 4 continues to move upward, and the teeth on the rack 404 contact and mesh with the first gear 202, so that the rack 404 moves upward to drive the first gear 202 to rotate, so that the rotating shaft 201 drives the filter plate 2 to rotate, so that the filter plate 2 tilts toward the lower material trough 105, and the impurities on the filter plate 2 move downward along the filter plate 2 and enter the lower material trough 105, so as to be discharged through the lower material trough 105.

[0033] Among them, a plurality of blades 303 are evenly fixed on the outer wall of the heat absorbing tube 3 along the circumferential direction, and the blades 303 increase the heat absorbing area and improve the heat absorbing effect.

[0034] Among them, support platforms 104 are fixed on the two side walls of the processing box 1 at the outer end positions corresponding to the filter plate 2, and the bottom of the outer end of the filter plate 2 is located on the support platform 104. When the filter plate 2 is in a horizontal state, the support platform 104 and the top of the discharge chute 105 provide support for the filter plate 2, thereby improving the position stability of the filter plate 2.

[0035] Embodiment 2

[0036] The structure of this embodiment is basically the same as that of the first embodiment, except that the heat absorption tube 3 is rotatably connected to the side wall of the processing box 1, and a second gear 305 is fixed at one end, and multiple second gears 305 are meshed with each other, and one of the second gears 305 is connected to a driving component, and the multiple second gears 305 are driven by the driving component to rotate the heat absorption tube 3, thereby rotating the blades 303, and stirring the drilling fluid at the bottom of the processing box 1 through the blades 303, so that the blades 303 and the heat absorption tube 3 can fully contact the drilling fluid to absorb heat, thereby improving the heat absorption effect.

[0037] Embodiment 3

[0039] When the filtered drilling fluid is charged into the water collecting bucket 103, it falls through the rectangular notch at the bottom and falls onto the corresponding shifting blade 303, so that under the impact of the water flow, the shifting blade 303 drives the shifting shaft 302 to rotate, and then the second gear 305 drives the heat absorption tube 3 and the blade 303 to rotate through the first pulley 304 and the second pulley 306, thereby realizing the driving of the second gear 305 and reducing the number of motors.
