Description

Technical Field

[0001] The utility model belongs to the technical field of ceramic bar screening equipment, and particularly relates to a ceramic screen bar mounting seat which is convenient for disassembling and replacing a screen bar plate. Background Art

[0002] A bar screen is a common screening device, and bar screens are used to screen materials in many industries, such as waste treatment, coal mines, rock mines, etc. There are a variety of existing bar screens, and the screen bars in different fields will be improved differently, especially the fixing method of the screen bars. The patent document CN213255555U discloses a bar screen plate, which can install the bar on the cross beam only through nuts and countersunk bolts, and can realize the detachable connection of the bar. At the same time, during assembly, positioning and clamping can be completed by setting a clamping groove and a clamping block, which has good convenience. However, in the actual use process, there are still too many bolts for fixing, and the workload during assembly cannot be well saved. Therefore, how to ensure modularity and easy disassembly while meeting better optimization of the assembly process and improving the assembly efficiency is an important factor in improving the overall application ability of the bar screen.

[0003] The patent document CN218591040U discloses a mounting seat for fixing the aperture of a ceramic screen bar, which includes a frame side plate. A plurality of support plates are fixedly connected inside the frame side plate. Two adjacent support plates form a group. A control plate is bolted to each support plate. A plurality of mounting grooves are arranged on the control plate at uniform intervals. By controlling the gap between the mounting grooves, the distance between the screen bars mounted on the control plate can be controlled. It also includes a connecting plate connected to the corresponding mounting grooves of the control plates in the same group. A first limiting plate and a second limiting plate for limiting are arranged on the connecting plate. A second connecting pipe corresponding to and cooperating with the first connecting pipe on the control plate is arranged on the second limiting plate. After all the connecting plates are inserted into the mounting grooves, a round steel can be used to fix and limit the connecting plates in the same column on the control plate, which not only makes the screen bars more modular, but also optimizes the assembly process, reduces the use of bolts, and is more convenient for future disassembly and replacement. However, in this patented technology, the control plate is still installed on the support plate through bolts and nuts. On the one hand, since this connection is assembled inside the screen box, the assembly operation space is limited, which is time-consuming and laborious. On the other hand, when screening materials, especially wet materials, the bolts and nuts at the connection between the control plate and the support plate are prone to corrosion and rust, resulting in difficulty in quickly disassembling and assembling during the process of replacing the control plate according to the type of screened materials, increasing the work intensity and affecting the production efficiency of the enterprise to a certain extent. Therefore, it is necessary to improve the structure of the current ceramic screen bar mounting seat to better meet the requirements of assembly operations and production operations.

[0004] In addition, in the prior art, the U-shaped support plates of the ceramic sieve bar mounting seats are usually formed by cutting a rectangular square steel in the middle into two U-shaped support plates. The defect of this processing method is that during the cutting process, the front and rear support plates in the U-shaped support plate are prone to deformation and cannot maintain good parallelism. Since the sieve bar plate is closely attached and installed on the outer side of the front support plate, this results in the sieve bar plate being unable to be installed normally and smoothly. In addition, even if the sieve bar plate is installed, it will affect the consistent surface fitting and supporting effect of the front support plate on the sieve bar plate, affecting the supporting strength of the sieve bar plate and the installation accuracy of the sieve bar plate, and further affecting the installation accuracy of the ceramic sieve bars on the subsequent sieve bar plate and the use effect of the bar screen equipment.
