Description

Technical Field

[0001] The utility model belongs to the technical field of cleaning and filtering of viscous materials, and relates to a viscous filtering structure with a negative pressure cleaning function. Background Art

[0002] Filtration of sticky materials usually involves the use of specific filtration equipment and methods to remove impurities and solid particles from the material. Fiber bags are usually used as filter media. The pore size of the bag and the adsorption effect of the fiber surface can intercept the solid particles in the sticky material, but due to the poor fluidity of sticky materials, if the material cannot flow quickly under negative pressure during the cleaning and filtration process of sticky materials, a series of problems will arise. These problems not only affect production efficiency, but may also have a serious impact on product quality and process safety.

[0003] First, the inability of the material to flow quickly under negative pressure will lead to low filtration efficiency. Viscous materials have poor fluidity. If effective negative pressure flow cannot be formed during the filtration process, the material's penetration speed in the filter will slow down and the filtration cycle will be extended. As a result, the processing capacity per unit time decreases, which directly affects production efficiency.

[0004] Secondly, poor material flow can easily cause filter blockage. Impurities and particles in viscous materials are more likely to settle on the filter surface when the flow is slow, causing blockage. Blockage not only reduces the filtering effect, but may also cause the filter to fail, requiring frequent replacement or cleaning, increasing maintenance costs.

[0005] In addition, if the viscous material cannot flow quickly during the filtration process, it will cause uneven distribution of the material in the filter. Uneven distribution may cause the material to be too thick in some areas and too thin in other areas. In this case, the filtration effect is inconsistent and the product quality is difficult to guarantee.

[0006] Finally, the inability of materials to flow quickly under negative pressure may also cause safety issues. Viscous materials may accumulate during the filtration process due to poor flow, and the accumulated materials may cause fire or explosion under high temperature or high pressure. This will not only damage production facilities, but may also threaten the lives of operators.

[0007] In summary, the inability to make the material flow quickly under negative pressure during the cleaning and filtering process of viscous materials will lead to low filtration efficiency, filter blockage, product quality problems and safety hazards. Therefore, there is an urgent need for a viscous filtration structure with negative pressure cleaning function to solve the above problems. Utility Model Content

[0030] The interior of the feed port 100 is interconnected with the interior of the feed pipe 110 , the interior of the feed pipe 110 is interconnected with the interior of the pressure chamber 140 , and the interior of the pressure chamber 140 is interconnected with the pressure relief pipe 120 and the negative pressure pipe 130 .

[0031] An air pump 220 for controlling the extraction and release of air pressure is provided on the rear side of the pressure relief tube 120 and the negative pressure tube 130.
