SU916357A1 - Device for protecting conveyer from severe environment - Google Patents

Description

one

The device relates to lifting equipment and can be used on overhead conveyors when operating in conditions of harmful environments in the drying, painting booths, in the cells of powder coating and others.

A device for protecting the conveyor from the influence of a harmful environment is known, in which the conveyor is enclosed in a casing having a groove with an elastic seal that slides apart when the suspension holders pass (1).

The closest to the proposed device is to protect the conveyor from the influence of the harmful environment, which contains flexible protection elements and suspension brackets mounted with the possibility of passing between the protection elements (2).

A disadvantage of the known devices is that the security elements are deformed, forming in the places of contact with the holders of the suspensions of the slit, through which the harmful environment penetrates to the conveyor.

The purpose of the invention is to increase the reliability of the conveyor by creating a more efficient sealing.

This goal is achieved in that the device to protect the conveyor from the influence of harmful environment, containing flexible protection elements and suspension holders installed with the possibility. .

In addition, the tape is made in the form of pneumatic chambers, and the tape can be covered with an external brush cover.

1 shows a device for protecting the conveyor using pneumatic chambers, front view; FIG. 2 is a section A — A in FIG. one; on fig.Z - the device with use of a brush cover; on figure 4 - section B — B on fig.Z.

The device contains flexible elements 1 and 2, made in the form of ribbons 3, freely mounted on non-driven rollers 4, installed, for example, on the -cap 5 of the drying chamber (not shown) during movement of the conveyor 7 interact with the belts 3. Tape 3 is made pneumatic

The device works as follows. five

The holders of the 6 hangers are in constant coverage with pneumatic chambers 8 or brush cover 9.

When the holders move in the groove of the roof 5 of the drying chamber, due to the 1θ friction they drive the belts 3., which run freely around the rollers 4.

Thus, the holders 6, being in close contact with the belts 3, 15, do not allow dust or gas to penetrate into the external environment. To the elements of the conveyor 7.

The application of the proposed device allows creating more reliable conditions for the operation of the conveyor,

; and also to reduce energy consumption compared with the prototype due to ·

, elimination of pipelines and devices for forcing air into them. 25
