Valve-type quick-change liner unit for discharge hoppers

Abstract

The invention belongs to the technical field of transfer equipment in mine, metallurgy and coal mine industries, and in particular, relates to a valve type lining plate quick replacement device for a discharge funnel. The device comprises a material receiving side plate of the discharge funnel; an easy wear lining plate replacement port is formed in the material receiving side plate; two limiting strip plates are arranged at the left and right side edges of the easy wear lining plate replacement port, and are connected with a lining plate rotating door assembly; the lining plate rotating door assembly consists of a rotating door sheet, two folds, a door sheet switch, a set of support plates, a set of lining plate hanging plates, a lining plate and a set of fastening bolts; and a seal pressing bar is arranged on the peripheral surface of the inner side of the rotating door sheet. The device skillfully designs a detachable mobile door to the openable rotating door plate; the lining plate to be replaced is hung on the rotating door plate; the installation can be finished along with the closing of the rotating door plate; the complex work of replacing the lining plate in the discharge funnel becomes simple and convenient; the maintenance workload is reduced; the maintenance time is shortened; and the operability is improved.

Problems solved by technology

[0002] The liners of the discharge hoppers of the transfer conveyors used in mining, metallurgy, and coal mining industries have been worn by materials for a long time, and have become well-known vulnerable parts. Most of these damaged liners must be replaced inside the funnel. Due to the narrow working space, the replacement time is long , so the entire transportation system is shut down for a long time

In order to solve the above problems, more wear-resistant liners are generally used, which not only increases the maintenance cost, but also shortens the maintenance time; Chinese patent: 201320858416.8 discloses the "integrated liner". A detachable bottom plate is installed on the bottom plate, and the bottom plate is equipped with a wear-resistant plate, which is manually installed on the outer surface of the funnel. This method does not need to enter the inside of the funnel to replace the liner. However, if it is used on a larger conveyor, the bottom plate and The weight of the liner will also be very large, and hoisting tools need to be erected, and the height of the space here is limited, and the conditions for hoisting are not available, which will cause a long maintenance time; Chinese patent 201220307603.2 discloses "a hanging liner" , this method also requires maintenance personnel to go to the inside of the funnel for maintenance, and there are also problems such as narrow internal space and difficult operation.
