Description

Technical Field

[0001] The utility model belongs to the technical field of cyclones, in particular to a cyclone underflow box cleaning device. Background Art

[0002] A hydrocyclone is a common separation and classification device that typically operates on the principle of centrifugal sedimentation. When the two-phase mixture to be separated enters the hydrocyclone tangentially from its periphery at a constant pressure, it generates intense three-dimensional, elliptical, highly rotating, shearing turbulence. Due to the size difference between coarse and fine particles, they are subject to varying degrees of centrifugal force, centripetal buoyancy, and fluid drag. As a result of centrifugal sedimentation, the majority of coarse particles are discharged through the hydrocyclone's underflow outlet, while the majority of fine particles are discharged through the overflow pipe, achieving the desired separation and classification.

[0003] During the operation of the cyclone, coarser particles enter the underflow box through cyclone classification. When the solid content in the underflow box is high, the discharge pipe of the underflow box is easily blocked, causing the underflow box to overflow, seriously affecting the normal organization of production. In addition, the discharge pipe of the underflow box needs to be manually cleaned after being blocked, which increases the labor intensity of the staff. Utility Model Content

[0004] In order to solve the problems in the above-mentioned background technology, the utility model provides a cyclone underflow box cleaning device. After the water supply valve is opened, water flows into the underflow box through the water supply pipe, thereby diluting the material in the underflow box. The material can then be discharged from the discharge pipe, reducing the occurrence of blockage in the discharge pipe and reducing the labor intensity of the staff.

[0005] The utility model provides a cyclone underflow box cleaning device, comprising a flushing assembly installed on the underflow box, the bottom of the underflow box is connected to a discharge pipe, the flushing assembly comprises a water supply pipeline, one end of the water supply pipeline is connected to a water source, the other end of the water supply pipeline extends into the underflow box, and a water supply valve is installed on the water supply pipeline.

[0025] A plurality of water nozzles 34 are installed around the annular pipeline 30, and the water nozzles 34 are facing the inner wall of the underflow box 1, so that water can be sprayed in multiple directions to better dilute the material; a U-shaped protective shell 35 is fixedly connected to the inner wall of the underflow box 1, and the protective shell 35 covers the annular pipeline 30 and the water nozzles 34. The top of the protective shell 35 is fixedly connected to the inner wall of the underflow box 1, and a gap is left between the bottom of the protective shell 35 and the inner wall of the underflow box 1, so that the water sprayed from the water nozzles 34 flows downward along the inner wall of the underflow box 1. The protective shell 35 can better protect the water nozzles 34 and reduce the situation where the water nozzles 34 are blocked by materials.

[0026] An inclined pad 36 is fixedly connected to the bottom wall of the underflow box 1, and the top surface of the pad 36 is inclined in the direction of the discharge pipe 2, so that the pad 36 can guide the diluted material to flow in the direction of the discharge pipe 2, thereby facilitating the discharge of the material; a plurality of water outlet holes 37 are provided on the top surface of the pad 36, and a connecting pipe 38 is connected to the water supply pipe 32.
