Inner cover cleaning device for cover type bright annealing furnace

Abstract

The invention relates to an inner cover cleaning device for a cover type bright annealing furnace. The inner cover cleaning device for the cover type bright annealing furnace comprises an inner coverbody and a bottom plate, wherein multiple positioning seats are arranged on the top part of the bottom plate; multiple lifting lugs are formed in a way of outwards stretching out from the bottom partof the inner cover body, and are arranged on the positioning seats in a one-to-one correspondence way; a transmission mechanism is arranged under the bottom plate and comprises a screw rod; the top part of the screw rod penetrates through the bottom plate and stretches into the inner cover body; the screw rod is in screw-thread fit to the bottom plate; a cleaning mechanism is arranged on the screwrod and is located above the bottom plate; a collecting tank is arranged under one side of the bottom plate; and a top surface of the bottom plate is slantways arranged toward a direction of the collecting tank. The inner cover cleaning device for the cover type bright annealing furnace provided by the invention has the beneficial effects that the structure arrangement is reasonable; through arranging the lifting lugs and the positioning seats, the inner cover body can be conveniently moved by utilizing a crane so as to be positioned and placed; and through arranging the transmission mechanism, and arranging the cleaning mechanism on the screw rod, the cleaning mechanism can be conveniently moved by utilizing the transmission mechanism, so that an inner wall of the inner cover body is completely cleaned.

Description

technical field [0001] The invention relates to the technical field of bell-type furnace cleaning devices, in particular to an inner cover cleaning device for a bell-type bright annealing furnace. Background technique [0002] In the processing and production of metal sheets and strips, annealing is an essential process for the deep processing and performance treatment of materials, and coil bell annealing is the most widely used method, with less investment in equipment, less space occupied, and materials Performance is easy to control. During the use of the bell annealing furnace, the inner cover will be rusted after repeated heating. At the same time, the inner wall of the inner cover is also prone to carbides produced by the oil on the roll at high temperature. If these rusts and carbides are not cleaned in time, Due to the forced circulation of the airflow during the annealing process, the product will be polluted and the quality of the product will be affected.

Problems solved by technology

During the use of the bell annealing furnace, the inner cover will be rusted after repeated heating. At the same time, the inner wall of the inner cover is also prone to carbides produced by the oil on the roll at high temperature. If these rusts and carbides are not cleaned in time, Due to the forced circulation of the airflow during the annealing process, the product will be polluted and the quality of the product will be affected. Therefore, it is necessary to clean the inner cover of the bell furnace regularly.

However, the inner cover of the bell-type furnace is relatively large, its inner diameter is generally more than 2 meters, and its height is generally more than 6 meters. When cleaning manually, people need to stand in the furnace and clean it with a wire brush. If the height is not enough, a ladder needs to be erected, which is labor intensive Big, harsh working environment, low work efficiency, and unsafe
