Description

Cyclone convenient for replacing underflow lining

Technical Field

The utility model relates to the technical field of cyclones, in particular to a cyclone with an underflow liner convenient to replace.

Background

It is well known that cyclones are currently widely used in mining, metallurgy, electrical environmental protection, petroleum, chemical industry and food industry. The cyclone uses water as medium, and utilizes external pump or gravitational field to transfer power, and utilizes the rotating flow field to accelerate the sedimentation speed of solid-phase particles in the water medium and increase the sedimentation speed difference of coarse and fine particles in the water medium so as to implement quick separation and classification of particles with different sizes.

According to the working principle and working environment of the cyclone, the inner wall of the cyclone is washed and worn by particles in ore pulp in the running process, so that the cyclone often needs special wear-resistant materials. The common wear-resistant materials of the cyclone lining comprise high-alumina ceramic, rubber, polyurethane and the like, the underflow pipe of the cyclone is generally composed of an underflow lining and an underflow shell, the underflow lining is generally processed by ceramic, silicon carbide, rubber and other materials, and the underflow shell is generally processed by steel plates to ensure the strength. The underflow pipe of the cyclone is positioned at the lowest end of the whole cyclone and is also the most severely worn position, the wear is required to be checked regularly according to the use condition, and a new underflow lining is required to be replaced when the wear period is reached or the wear is excessive. The replacement period of the underflow lining is generally 1-6 months, and is one of the most frequent components for cyclone maintenance.

In the actual use process, as an installation gap is formed between the underflow shell and the underflow lining, slight shaking is caused between the underflow lining and the underflow shell in industrial production, so that a very small part of slurry leaks into the space between the underflow lining and the underflow shell through a rubber sealing gasket between an underflow outlet and an upper cone of the cyclone, and the gap between the underflow shell and the underflow lining is filled with fine silt in the slurry in the cyclone to be very compact due to long-time production operation. And thus the friction between the underflow lining and the underflow outer casing is great, and the fine silt sand clamped in the gap is difficult to wash out by water, so that the underflow lining is difficult to detach and replace.

According to the utility model, the cyclone with the publication number of CN212883010U is characterized by comprising a cylinder body, a conical body, a feed pipe, an overflow pipe and an underflow pipe, wherein the underflow pipe consists of a flange plate, an underflow shell and an underflow lining, the outer wall of the upper end of the underflow shell is connected with the flange plate, the inner wall of the underflow shell is provided with the underflow lining, the underflow lining is provided with a tubular shape, support strips protruding in the vertical direction are uniformly distributed on the circumference of the outer wall of the tubular underflow lining, the support strips are contacted with the underflow shell to form a slurry discharge gap between the support strips and the underflow shell, an annular supporting plate is arranged on the inner wall of the lower end of the underflow shell, a slurry discharge hole communicated with the slurry discharge gap is arranged on the annular supporting plate, and slurry between the underflow shell and the underflow lining is discharged through the slurry discharge hole and the slurry discharge gap.

However, in the above scheme, the tubular underflow lining supports the bottom of the underflow lining only through the annular supporting plate, so that the stability of the underflow lining in actual work is insufficient, and in addition, a filtering device is not arranged at the upper port and the peripheral gap of the underflow lining, so that some raw pulp which is not purified and is mixed between the underflow lining and the underflow pipe is directly mixed with the underflow liquid to cause the underflow liquid to be impure.

In view of this, the present utility model proposes a cyclone that facilitates replacement of the underflow liner.
