Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a high-pressure filter press with an automatic locking oil cylinder. Background Art

[0002] Working principle of filter press: The filter press consists of multiple filter chambers, each of which contains a filter plate and a filter frame. The suspension is delivered to the filter chamber by a feed pump, and a filter layer is formed between the filter plate and the filter frame. As the pressure increases, the solid particles in the suspension are trapped in the filter layer, while the liquid flows out through the filter layer and becomes the filtrate.

[0003] The chain filter press connects the filter plates through chains. When the chain drives the filter plates to move, a filter chamber is formed. After the material to be processed is added to the filter chamber, pressure is applied to make the liquid pass through the filter cloth and leave the solid. After the filtration is completed, the chain drives the filter plates to move and the filter cake is unloaded. However, in actual use, it is found that the chain filter press has a large noise, which may have a certain impact on the surrounding environment. In addition, during the chain drive process, the movement of the filter plate may not be stable, and the pressure received by the filter plate is low. For this reason, we have made improvements and proposed a high-pressure filter press with an automatic locking cylinder. Utility Model Content

A guide element 47 is provided in the middle of the cylinder bottom 41. The threaded rod 46 slidably cooperates with the guide element 47. In the actual implementation process, the piston 1 45 is driven by injecting hydraulic oil into the cylinder barrel 42, thereby driving the threaded rod 46 to move and achieve extension.
