Description

Technical Field

[0001] The invention belongs to the field of filter presses, and in particular relates to an automatic beam clamping and rotating device in an automatic beam production device of a plate-frame filter press. Background Art

[0002] Filter press is a commonly used solid-liquid separation equipment, which is a kind of equipment that separates the solid phase and liquid phase in a mixed liquid by physical means; most of the existing filter presses have a frame and filter plate assembly mainly composed of a clamping plate, a thrust plate, a cylinder head, and a beam. The main girder is composed of a hydraulic system and a feeding system. For a filter press, the main girder is the supporting component of the entire filter press. Especially for a large filter press, the weight of the main girder can reach ten tons and the length can be tens of meters. Therefore, the production of the main girder has an important impact on the quality and reliability of the main girder. The existing production method of the main girder of a filter press often adopts the following steps: 1. The rectangular pipe is hoisted onto the platform, and the required length is measured manually with a ruler to draw the cutting line. 2. Manual flame cutting is performed according to the drawn line, and the line cuts out half of the cross section of the rectangular steel pipe, and then the other half of the cross section is cut on the reverse side of the rectangular steel pipe. 3. The cut section is manually polished. 4. Manual measurement is performed and lines are drawn to determine the position of the auxiliary parts on the main girder. 5. The auxiliary parts are welded by electric welding. After the accuracy of the position is determined, continuous welding is performed. Because the filter press requires the geometric regularity of the main girder, a large amount of deformation cannot be generated during welding, and layered welding is required, which requires the main girder to be repeatedly turned over for many times. 6. The welded part is polished and flat. From the above processes, it can be seen that the existing method for making the filter press beam has the following defects: 1. Low manufacturing precision, manual measuring and manual welding result in low precision; 2. Low production efficiency, multiple manual reversals, multiple layered welding, resulting in low work efficiency; 3. Unstable quality, manual measurement, line drawing, and welding are extremely random; 4. High labor intensity for operators. Summary of the invention
