Description

Technical Field

[0001] The utility model relates to the field of filter presses, in particular to a filter press for sewage treatment. Background Art

[0002] Domestic sewage is actually the wastewater generated in people's daily lives. For example, the water used for bathing, washing clothes, washing dishes, and cooking, as well as the water used for flushing toilets, are all domestic sewage. This sewage contains some organic substances, pathogens, and nutrients, so it cannot be directly discharged into the environment and needs to be treated before it can be safely discharged or reused.

[0003] A filter press is a mechanical device that uses a special filter medium to apply a certain pressure to an object to allow the liquid to permeate out. It is a commonly used solid-liquid separation device. The filter press was applied to chemical production in the early 18th century and is still widely used in industries such as chemical engineering, pharmaceuticals, metallurgy, dyes, food, brewing, ceramics, and environmental protection. The filter press has the characteristics of stable performance, convenient operation, safety, and labor saving. Its filter plates are processed from seamless steel pipes and precision cast from plastic-steel filter plates, which are resistant to high temperature and pressure and durable.

[0004] The filter press can effectively separate the solid substances and liquid substances in the sewage, making the solid substances form cakes or blocks, while the liquid substances are filtered out to achieve the purpose of purification. The applications of the filter press in sewage treatment include sludge dewatering, advanced sewage treatment, industrial wastewater treatment, etc. Application No.: CN202022970263.9 discloses a filter press for sewage treatment. Through the cooperation of a slider and a chute, it is convenient for the staff to take out the collection box from the collection chamber. Through the setting of elastic buffer blocks, it can play a certain buffering role during extrusion to avoid the filter plate being deformed due to excessive impact force. However, when this device is in use, it is impossible to clean the adhered mud blocks. When the filter plate drops the solid objects, a part of them often remains adhered to the filter holes, and these adhered mud blocks will affect the normal use of the filter press later, resulting in a decline in the use effect of the filter press.

[0005] Therefore, it is necessary to provide a filter press for sewage treatment to solve the above technical problems. Summary of the Utility Model
