A rotary installation structure of the mold core center of a high-pressure filter press

Abstract

The invention relates to the technical field of filter pressing, particularly to a rotary mounting structure for use in a center of a cavity of a high-pressure filter press. A mounting piece is fixed on a moving beam through first bolts. An upper die is fixed on the mounting piece through second bolts. A rotary disc is connected with a fixing disc through a connecting piece. A fixing piece is of an annular shape. Diameter of the outer wall of the rotary disc is larger than that of the inner wall of the fixing piece and is smaller than that of the outer wall of the fixing piece. The fixing piece sleeves the connection piece and can rotate relative to the rotary piece. The lower end of the mounting piece is provided with a rotary chamber which is internally provided with the rotary disc. The fixing piece is fixed at the lower end of the mounting piece. Axial movement of the rotary disc is limited by the mounting piece and the fixing piece which allow the rotary disc to rotate only. The fixing disc is fixed at the upper end of the upper die. According to the arrangement, the upper die and the mounting piece oppositely rotate, with the heavy upper die free of rotation and the mounting piece rotated and fixed on the moving beam, thus the upper die is mounted onto the moving beam, and mounting time is saved.

Description

technical field [0001] The invention relates to the field of filter press technology, in particular to a mold core center rotary installation structure of a high-pressure filter press. Background technique [0002] The vertical high-pressure filter press can use the weight of the mold itself to increase the pressure of the material during the filter press, which solves the problem of insufficient pressure during the high-dryness filter press. When dealing with tailings and other materials, it can perform high-dryness pressure filter. [0003] For example, in the process of further processing tailings into raw materials such as construction, it is first necessary to press the tailings and other materials for high-dryness filter dehydration, using press dehydration to use high pressure to press out the moisture in the materials . The vertical filter press uses the weight of the mold core in the mold to increase the pressing pressure on the material to better reduce the moist...

AI Technical Summary

Problems solved by technology

The vertical filter press uses the weight of the mold core in the mold to increase the pressing pressure on the material to better reduce the moisture content of the material. Although the problem of pressure is well solved, the weight of the mold core makes the vertical filter press It is very inconvenient to install the equipment

[0004] In the prior art, when installing the mold core, not only the alignment position needs to be moved horizontally, but also the rotating mold core needs to be aligned with the bolt holes. Because of the large weight of the mold core, the efficiency of mold core installation is reduced and the installation cost is increased.
