Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a bag filter. Background Art

[0002] The bag filter is mainly composed of the filter cylinder body, filter cylinder cover and quick opening mechanism, stainless steel bag reinforcement net and other main components. This series of filters is a pressure filter device. The raw liquid flows into the filter bag in the reinforced net from the feed inlet, and is pressurized. The qualified products penetrate the filter bag and are discharged from the discharge port to enter the next process. The impurity particles are captured by the filter bag. The whole process is efficient and simple, and it is very convenient to replace the filter bag, and basically no material consumption is generated. The bag filter of the existing technology has problems such as inconvenience in movement when in use. In this regard, we propose a bag filter. Utility Model Content
