Rake-free thickening device including driving area

Disclosed is a rake-free thickening device including driving area. The device includes a feed assembly, a diversion assembly and a clean coal collection assembly. The clean coal collection assembly includes a driving area. The diversion assembly includes a central tank. Slime water passes through the feed assembly and flows with a medicament from an upper part of the central tank to a middle of the central tank, and then diffuses around. Bubbles carry the fine slime up after reacting. The driving zone drives the dispersed bubbles to a defoaming zone located in the middle of the central tank. The slime water in the central tank flows through the central tank after defoaming. With the continuously filling of slime water, the slime water above the central tank overflows the central tank to the clean coal collection assembly within the diversion and settlement area.

Flow back separation system and method
11634953 · 2023-04-25 · ·

A flow back system for separating solids from a slurry recovered from a hydrocarbon well. The system includes a V-shaped tank with a first series of baffles configured to cause the settling of solids that are moved by a shaftless auger to a conduit fluidly connected to hydrocyclones mounted over a linear shaker. The overflow from the hydrocyclones is discharged through a second conduit back into the tank for processing by a second series of baffles resulting in a clean effluent. The clean effluent is recirculated in the well.

Wastewater spray distribution apparatus
11471899 · 2022-10-18 · ·

A wastewater spray distribution apparatus is operative to distribute wastewater produced by a sewage treatment system (10) onto a ground level (22) through operation of sprayers (118, 260). The exemplary sprayers include a manifold (142, 262) that includes outlet nozzles (158, 264) that can be readily removed and replaced. The exemplary manifold further includes interior areas bounded by surfaces that slope continuously downward from the outlet nozzles to the manifold inlet to assure the draining of water therefrom. Each of the nozzles include a base (140) which includes brake (207). A brake is provided in each nozzle and is adjustable to provide brake force to limit rotational movement produced by the thrust of water passing from the outlet nozzles to assure that the sprayer operates at the appropriate rotational speed. Alternative arrangements include manifolds including fixed or adjustable flaps and radially outwardly adjustable arms to adjust rotational properties.
