Embodiment Construction
[0027] In order to make the purpose, technical solution and advantages of the present invention clearer, the specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings.
[0028] The core idea of the present invention is to first weld the diversion cloth into a whole, then turn the welded diversion cloth layer by layer, and place a filter screen between two adjacent diversion cloths after each page turning Membrane, thus forming a membrane layer structure in which the guide cloth and the filter membrane are stacked alternately.
[0029] as attached figure 1 Shown is a flow chart of the preparation method of the present invention, specifically comprising:
[0030] S01: Weld the top ends of the N layers of flow guide cloth together to form a welded flow guide cloth, and place the welded flow guide cloth on the page-turning device; wherein, the page-turning device is used to turn the pages of ...

A method for preparing a film layer in an industrial filter core disclosed by the present invention comprises the following steps: S01: Welding the top ends of N layers of guide cloth together to form a welded guide cloth, and placing the welded guide cloth on a page-turning device; S02: The page-turning device turns the first layer of guide cloth in the welding guide cloth; S03: The traction jaw clamps the filter film on the lifting plate, and drives the filter film to move to the first layer of guide cloth above the cloth; S04: the pulling jaws loosen the filter film and return to the initial position, so that the filter film is placed above the first layer of guide cloth; S05: the page turning device sequentially welds the first layer of guide cloth The second layer to the Nth layer of diversion fabrics are turned over, and steps S02-S04 are repeated respectively, so that the filter membranes are stacked between two adjacent layers of diversion fabrics. A method for preparing the film layer in an industrial filter element provided by the invention, first welds the diversion cloth together, and then puts the filter mesh layer into the gap of the diversion cloth layer by layer, thereby forming the diversion cloth and the filter mesh A whole.
Description
technical field [0001] The invention relates to the field of industrial filter elements, in particular to a method for preparing a film layer in an industrial filter element. Background technique [0002] Industrial filter elements are widely used in the production process of chemical food and other industries to purify industrial sewage, so as to achieve the purpose of grading and reusing sewage. The current industrial filter element is wound and formed by alternately stacking welded guide cloth and multi-layer filter membrane. [0003] In the existing production process, the stacking method of the diversion cloth and the filter membrane in the industrial filter element is to put a layer of diversion cloth first, and then put a layer of filter membrane, and then form a stacked diversion cloth and filter membrane after repeated times filter membrane. Then, after stacking the diversion cloth and the filter membrane, it is necessary to carry out subsequent processing and win...
