Cyclone desander capable of cleaning solids in real time

Abstract

The invention discloses a cyclone desander capable of cleaning solids in real time, belonging to the field of desanding equipment. The rotational-flow grit chamber comprises an outer cyclone tube andan inner cyclone tube, wherein the bottom of the outer cyclone tube is provided with a solid treatment case used for treating screened solid particles, and the solid treatment case is in communicationwith the inner cavity of the outer cyclone tube. According to the rotational-flow grit chamber capable of cleaning solids in real time, the separated solid particles are piled up on the bottom of theouter cyclone tube, so the flow rate of water flowing through the inner cyclone tube is reduced, a sealing piston in a movable sealing tube moves downward due to increase of downward pressure, and avalve ball seals the movable sealing tube and the inner cavity of the outer cyclone tube; at the same time, a valve core blocks the bottom port of the inner cyclone tube, and the movable sealing tubeis moved downward by pressure, so the solid particles in the movable sealing tube flow through a through groove to the treatment case, and thus, the solid particles are discharged and cleaned in realtime according to the amount of the solid particles in the outer cyclone tube without shutdown of related equipment, which enables the working efficiency of the cyclone desander to be improved.

Description

technical field [0001] The invention relates to the field of desandering equipment, in particular to a cyclone desander capable of cleaning solids in real time. Background technique [0002] Cyclone desander is a common solid-liquid separation equipment. By controlling the water flow from the water inlet of the desander to the equipment under a certain pressure, a strong rotational movement is generated. Due to the different densities of sand and water, centrifugal force, Under the joint action of centripetal force, buoyancy and fluid drag, the water with low density rises and is discharged from the water outlet, and the sand with high density is discharged from the sewage outlet at the bottom of the equipment, so as to achieve the purpose of sand removal. It is widely used in well water sand removal , Coal washing water, industrial beneficiation, liquid degassing and separation of immiscible liquids. [0003] However, when the existing desander is in use, the solid particl...
