Description

Technical Field

[0001] The utility model belongs to the technical field of filter press equipment, and in particular relates to a fabric dyeing and finishing material filter press with a mud cleaning structure. Background Art

[0002] The filter press uses a special filter medium to apply a certain pressure to the object, so that the liquid is dialyzed out. It is a mechanical device that is commonly used for solid-liquid separation. Common filter presses include plate and frame filter presses, chamber filter presses, vertical filter presses and belt filter presses. It was used in chemical production in the early 18th century and is still widely used in chemical, pharmaceutical, metallurgical, dye, food, brewing, ceramic and environmental protection industries. In the modern green printing and dyeing industry, due to the requirements of clean production, filter presses are commonly used as equipment for recycling printing and dyeing waste liquid. Frame plate filter presses are more common in the dyeing and finishing industry. Frame plate filter presses are easy to maintain and use, and are often used for filtering and recycling dyeing and finishing waste liquid. After the printing and dyeing waste liquid is filtered by the filter press, the insoluble matter is effectively reduced, the storage pressure of the sedimentation tank is effectively reduced, the residence time of wastewater in the sedimentation tank is reduced, the concentration of toxic gases near the sedimentation tank is effectively reduced, and the risk of worker poisoning is reduced.

[0003] The frame-plate filter press is highly efficient in daily maintenance and cleaning, but its disadvantages are also prominent. The sludge on the filter plate of the common frame-plate filter press is difficult to remove. A common treatment method is for workers to use a long pole to knock on the filter plate to shake off the sludge blocks on the filter plate; or to improve the filter plate, set an air bag in the center of the filter plate, inflate the air bag, and when the surface of the filter plate is slightly deformed, the sludge loses its attachment and falls off. However, this method requires the redesign of the filter plate structure. In actual use, due to the need to withstand high pressure during the filtration process, structural failure often occurs. In order to solve the problem that the sludge on the filter plate is difficult to fall off smoothly, the utility model hopes to provide a fabric dyeing and finishing material filter press with a mud cleaning structure.
