Description

A kind of rotary liquid sealing cover of rotary distributor

technical field

The invention relates to the technical field of industrial furnace mouth sealing, in particular to a rotary liquid seal cover of an externally driven liquid-sealed rotary distributor.

Background technique

There are generally two forms of charging and distributing of bulk materials, namely bell-like fabric and bell-free fabric. Both forms have certain disadvantages. The bell-type material distribution is a material distribution method that uses the material bell to evenly distribute the loaded materials to the lower device. Since the shape of the material bell is fixed, there is a disadvantage that the material distribution angle cannot be adjusted during use. Although the bell-less material distribution overcomes the disadvantages of the material bell material distribution, its overall structure and driving device structure are complex, and because its main material distribution mechanism is set inside the industrial furnace, it is greatly affected by the high temperature in the furnace and other working conditions. It is prone to failure and difficult to replace components, which affects the continuity of production.

In order to overcome the above shortcomings, we have developed an externally driven liquid-sealed rotary distributor (as shown in Figure 1), which is used to load lump materials at various temperatures into the shaft furnace to achieve sealed charging and distribution operations. Stable operation, at the same time, the rotary distributor can be easily repaired and replaced.

The externally driven liquid-sealed rotary distributor includes a material distribution device 1, a rotary device 2, and a rotary liquid cover 3, etc., wherein the rotary cover 3 is a key component of the rotary distributor, and is used for vertical alignment during the process of rotating the material. The furnace acts as an effective seal. The connection between the conventional rotary distributor and the furnace mouth is usually sealed with a sealing ring. Due to working in a high temperature environment, the sealing ring will fail in a short period of time, the service life is short, and it is difficult to replace; therefore, it is necessary to provide an easy-to-replace and Maintenance, but also can play a role in the rotation of the effective sealing seal.
