Bentonite powder swabbing hydration apparatus

The embodiment of the invention provides a bentonite powder swabbing hydration apparatus, which comprises a slurry forming pot, a slag slurry pump, a swabbing hydrator and a bentonite barrel. A first end of the swabbing hydrator comprises a bentonite inlet cylinder and a water inlet cylinder which are tangent to each other. The bentonite inlet cylinder is connected to the bentonite barrel successively through a suction valve and a swabbing pipe. The water inlet cylinder is connected to the slurry forming pot successively through a water supply valve, a water supply pipeline and the slag slurry pump. A second end of the swabbing hydrator is connected to the slurry forming pot through a liquid drainage pipeline. By the use of the bentonite powder swabbing hydration apparatus provided by the embodiment, bentonite can be directly sucked from the ground and flows into a drilling fluid tank during drilling fluid raw-stock production. The bentonite powder and slurry-mixed water are uniformly mixed in an enclosed sta
