Description

Technical Field

[0001] The utility model relates to the technical field of filter presses, in particular to a sludge deep dehydration filter press which is convenient for replacing filter plates. Background Art

[0002] The filter press is a mechanical device that uses a special filter medium to apply a certain pressure to the object, causing the liquid to seep out. It is a commonly used solid-liquid separation equipment. At present, the common structure of the filter plate pressing of the plate filter press is hydraulic pressing, that is, the pressing plate is pushed by the hydraulic cylinder to press the filter plate frame, and a fixed connection is adopted between the hydraulic cylinder and the pressing plate. Since the pressing plate is heavy, in order to reduce the burden of the hydraulic cylinder, support rollers that can be mounted on the support beam are usually installed on both sides of the pressing plate. However, due to factors such as processing errors or long-term wear of the rollers, it is difficult to ensure that the support rollers can support the pressing plate. Among them, the filter pressing structure of a sewage treatment filter press with application number "CN202320828833.1" has the beneficial effect of: by setting a pressing mechanism and cooperating with a movable pressure plate assembly, the piston rod of the hydraulic cylinder and the movable pressure plate can move relative to each other, ensuring that the two sets of rollers can support the movable pressure plate. However, there is still room for improvement in the use of the filter press: after the filter press is used, the filter screen on the filter plate often has problems such as damage and needs to be disassembled and replaced. The existing filter press does not have a mechanism for replacing the filter plate, which makes replacement troublesome, time-consuming and labor-intensive. Utility Model Content

[0003] The purpose of the utility model is to provide a sludge deep dehydration filter press with easy filter plate replacement, so as to solve the problem that the filter screen on the filter plate of the filter press is often damaged after use and needs to be disassembled and replaced.
