The utility model provides a kind of drilling fluid circulation purification separation integrated machine, including support, elastic mechanism and agitating mechanism, the elastic mechanism includes contact block and moving plate, the upper surface of moving plate and the lower surface of contact block are fixedly connected, moving plate and contact block are used to provide elastic force, so that it can increase drilling fluid filtration efficiency;The agitating mechanism includes activated carbon plate and cotton, and the side surface of cotton is connected with the side surface of activated carbon plate.The utility model utilizes the lamination of contact block and second screening plate, so that it can drive moving plate to move under the influence of stamping, and it can rebound according to the movement of first screening plate and second screening plate, improve the elastic frequency of first screening plate and second screening plate, and simultaneously use activated carbon plate and cotton to adsorb and filter the high-temperature heated drilling fluid while patting, so that it can purify the high-temperature heated drilling fluid multiple times, thereby improving the purification effect of drilling fluid gas.

The utility model relates to a screening device technical field, concretely is a kind of powder high -efficient screening device, including support frame, the shape of support frame is L-shaped;Filtering assembly, the filtering assembly includes limit slot, the limit slot is opened in the top of support frame, the inside sliding connection of limit slot has connecting rod one, the side surface of connecting rod one is fixedly connected with several connecting rod two and several connecting rod two is annular array distribution.This powder high -efficient screening device, when carrying out filtering work to powder, staff can start motor one, so that elastic ball can produce high-frequency vibration, so that elastic ball can transmit high-frequency vibration to filter screen in uniform and stable mode, so that powder particle will be subjected to vertical and horizontal direction's compound impact force, make originally close gathering powder particle regain the ability of free dispersion, to make the flowability of powder on screen significantly enhance, can be more smoothly, quickly pass through sieve hole, improve screening efficiency.

This utility model discloses a sieving device for detecting heavy metal content in soil, including a base, a telescopic rod, a stirring cover, and detachable collection cups and filter cups. The telescopic rod is fixed to the top of the base and connected to the stirring cover. The filter layer is rotatably connected to the outside of the telescopic rod, with the filter cup installed in its middle. The stirring cover has a built-in drive motor that drives the stirring blades to extend into the filter cup. The rotating stirring blades break up clumps of soil and push fine particles through the sieve. Combined with the spring-loaded positioning of the filter layer, the magnetic fixation of the collection cup, and the anti-slip design of the rubber pad on the base, efficient anti-clogging, closed-loop operation, and stable operation are achieved. This device effectively solves the problems of easy clogging of the sieve, serious dust pollution, and easy equipment displacement in traditional sieving, significantly improving the efficiency and safety of soil heavy metal detection pretreatment.
