The invention aims to provide a sand setting tank with a diversion channel structure, which can efficiently treat flushing fluid, and the obtained flushing fluid can meet the recycling requirement.
The technical scheme adopted by the invention is as follows: the utility model provides a grit chamber that possesses water conservancy diversion structure, includes the jar body of inverted circular truncated cone, the internal center coaxial fixation of jar has a water filtering section of thick bamboo, the lateral wall bottom of a water filtering section of thick bamboo has the breakwater along circumference cladding, the lateral wall top intercommunication of a water filtering section of thick bamboo has the outlet pipe that passes the jar body and outwards stretch out, the locating hole of intaking has been seted up on the lateral wall top of the jar body, the inner wall of the jar body is provided with the water conservancy diversion way that the spiral descends along circumference, the upper end and the locating hole of intaking of water conservancy diversion way correspond.
The present invention is also characterized in that,
the upper end and the lower end of the water filtering cylinder are respectively abutted to the upper inner wall and the lower inner wall of the tank body.
The bottom of the tank body is communicated with a sand outlet pipe at the position outside the water filtering cylinder.
The top of the tank body is provided with a pull cover corresponding to the position of the water filtering cylinder.
The bottom end of the water filtering cylinder is communicated with a sand discharge pipe extending out of the tank body.
The invention has the beneficial effects that: according to the sand setting tank with the diversion channel structure, the well washing liquid is efficiently treated in a mode of combining precipitation and filtration, large-particle sand stones are fully precipitated in the tank body through the inclined inner wall of the tank body and the diversion channel in the process, small-particle sand stones are filtered out in the process of entering the water filtering cylinder, residual sand stones are precipitated in the water filtering cylinder, and finally obtained supernatant meets the recycling requirement.

Detailed Description
The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.
The invention provides a sand setting tank with a flow guide channel structure, which comprises a tank body 1 in an inverted circular truncated cone shape, wherein a water inlet positioning hole 5 is formed in the top end of the side wall of the tank body 1, a spirally descending flow guide channel 9 is arranged on the inner wall of the tank body 1 along the circumferential direction, the upper end of the flow guide channel 9 corresponds to the water inlet positioning hole 5, the lower end of the flow guide channel 9 extends to the bottom end of the tank body 1, a water filtering cylinder 2 is coaxially fixed in the center of the tank body 1, the upper end and the lower end of the water filtering cylinder 2 are respectively abutted to the upper inner wall and the lower inner wall of the tank body 1, a pull cover 7 is arranged at the top end of the tank body 1 corresponding to the position of the water filtering cylinder 2, a sand outlet pipe 6 is communicated with the position, outside the water filtering cylinder 2, a sand outlet pipe 8 extending out of the tank body 1 is communicated with the bottom end of the water filtering cylinder 2, a water baffle plate 3 is wrapped.
When the device works, a well washing liquid inlet pipe is respectively arranged in the water inlet positioning hole 5 and is aligned to the flow guide channel 9, so that the well washing liquid can flow out of the inner wall flow guide channel 9 of the tank body 1, the inner wall of the tank body 1 has a gradient, large-particle sand stones and sundries in the well washing liquid can be primarily settled when the well washing liquid flows down on the inner wall of the tank body 1, the well washing liquid falling outside the water filtering cylinder 2 at the bottom of the tank body 1 is precipitated again until the liquid level exceeds the water baffle 3 to overflow and enters the water filtering cylinder 2, the small-particle sand stones can be filtered and separated by the filter screen on the water filtering cylinder 2 in the process of entering the water filtering cylinder 2, and the supernatant liquid entering the water filtering cylinder 2 is. In this in-process, the design that the inner wall of the jar body 1 leaned out makes large granule grit and debris only subside being close to jar 1 inner wall one side of body, tentatively alleviates the filter screen pressure of a water filtering section of thick bamboo 2, and the liquid that falls into the outer water filtering section of thick bamboo 2 of jar body 1 bottom alleviates the filter screen pressure of a water filtering section of thick bamboo 2 once more through the sediment overflow. Wherein the water conservancy diversion 9 not only can carry out the water conservancy diversion to the liquid of downdraft, thereby make it along jar internal 1 inner wall one side inflow bottom alleviate large granule grit to the filter screen pressure of a water filtering section of thick bamboo 2, and can prolong liquid at the flow time and the distance of jar internal 1 inner wall, also can play the separation effect to the liquid that descends along jar internal 1 inner wall straight line simultaneously, delay its velocity of flow, thereby make the subsidence of well washing liquid outside jar body 1 water filtering section of thick bamboo 2 more abundant, the overall process can guarantee that the process of well washing liquid goes on with high efficiency. And finally, discharging the sand outside the water filtering cylinder 2 in the tank body 1 through a sand outlet pipe 6, discharging the sand in the water filtering cylinder 2 through a sand discharge pipe 8, and periodically opening the pull cover 7 to introduce clean water to clean the water filtering cylinder 2.
Through the way, the sand setting tank with the flow guide channel structure disclosed by the invention can be used for efficiently treating the well washing liquid in a mode of combining precipitation and filtration, in the process, large-particle sandstone is fully precipitated in the tank body 1 through the inclined inner wall of the tank body and the flow guide channel 9, small-particle sandstone is filtered in the process of entering the water filtering cylinder 2, residual sandstone water filtering cylinder 2 is precipitated, and finally the obtained supernatant meets the recycling requirement.
