Description

Technical Field

[0001] The utility model relates to the technical field of chopped cotton dehydration, in particular to a chopped cotton filter press. Background Art

[0002] Glass fiber is an inorganic non-metallic material with excellent performance. It comes in many types and has high insulation, heat resistance, corrosion resistance and mechanical strength. Therefore, it is widely used as a reinforcing material in composite materials. Glass wool is a type of glass fiber, which is a cotton-like material formed by fiberizing molten glass.

[0003] In the process of producing glass fiber and glass fiber products, there are a lot of chopped cotton. Directly discarding it is not conducive to environmental protection and energy saving. Therefore, the chopped cotton is usually collected and cleaned, and the water-containing chopped cotton after cleaning is filtered to reduce the water content in the chopped cotton so that it can meet the requirements of recycling. The chopped cotton after filtering is returned to the kiln for melting and reproduction to achieve environmental protection and energy saving.

[0004] Common filter presses include plate and frame filter presses, chamber filter presses, vertical filter presses and belt filter presses. The belt filter press consists of a frame, pressure rollers and a conveyor belt. The movement of the conveyor belt drives the material to move, and the rotation of the pressure rollers squeezes the material to discharge the moisture in the material. Since the chopped cotton will clump after being soaked in water, the chopped cotton is unevenly distributed on the conveyor belt. The upper surface of the chopped cotton is uneven and some parts are accumulated in clumps. If the pressure rollers are used directly for squeezing, the chopped cotton is unevenly stressed, thereby reducing the filtration effect of the chopped cotton. Utility Model Content

During the breaking process, part of the moisture in the chopped cotton is squeezed and falls from the mesh. The broken chopped cotton moves to between the upper pressing roller 41 and the lower pressing roller 42. The moisture in the chopped cotton is filtered out under the action of the upper pressing roller 41 and the lower pressing roller 42. The chopped cotton that has been dehydrated through two times of filtering is moved to the discharge hopper 12 for temporary storage, thereby realizing the filtering of the water-containing chopped cotton.

[0060] The water-containing chopped cotton is first broken up so that the clumped chopped cotton is evenly distributed on the conveyor belt 2. The broken up water-containing chopped cotton is then filtered, which reduces the probability of uneven force on the chopped cotton due to clumping. The two filtering operations reduce the water content in the chopped cotton, thereby improving the filtering effect of the water-containing chopped cotton.
