Embodiment Construction
[0017] Below in conjunction with specific implementation the present invention is described in detail:
[0018] Step 1, blanking: use laser cutting or water cutting on cold-rolled stainless steel to cut out a core board and two panels, and cut out the first water outlet hole 2 and several diversion grooves 3 on the core board 1. The first feed hole 4 (such as figure 1 ), the several diversion grooves 3 communicate with the water outlet holes 2, and on the panel 2, the second water outlet holes 5, the second feed holes 6, and the support net fixing frame 7 are cut out (such as figure 2 ), the length and width of the core board 1 are 2-5 mm smaller than the length and width of the panel 2 .
[0019] Step 2, cleaning: remove the dirt on the surface of the core board and panel.
[0020] Step 3, pressing: Discharge the panels, core panels, and panels in order from bottom to top, and place them on a horizontal workbench. The holes are coincident, and the three boards are pressed...

The purpose of the present invention is to provide a novel stainless steel filter plate manufacturing method, comprising the following steps: Step 1, blanking: use laser cutting or water cutting on cold-rolled stainless steel to cut out a core plate and two panels, step 2, Cleaning: remove the dirt on the surface of the core board and panel; Step 3, pressing: discharge the panel, core board, and panel in order from bottom to top, and place them on the horizontal workbench, the first water outlet and the second water outlet Coincidence, the first feed hole and the second feed hole coincide, use the hydraulic cylinder to press the three boards to ensure that the three boards are tightly fitted together; Step 4, spot welding: spot weld the two panels and the core board Together; step five, welding: loosen the hydraulic cylinder, and weld the outer ring of the panel and core plate by welding; step six, leveling; step seven: install the support net. Compared with the prior art, the invention has the advantages of convenient processing, reliable quality, low cost, effectively reduced welding deformation, and no need for milling after welding, making the appearance more beautiful.
Description
technical field [0001] The invention belongs to the field of filter presses of filter equipment, and relates to a method for manufacturing a stainless steel filter plate. Background technique [0002] The filter plate is the main filter element installed on the filter press. Under the action of the feed pressure, the material enters the filter plate chamber through the feed hole. The material and structural strength of the filter plate are directly related to the filtration safety and service life. The conventional filter plate is made of polypropylene. Due to the development of science and technology, the types of solid-liquid separation materials are gradually expanding. The pharmaceutical industry, food industry and some industries with high material temperature need to use metal filter plates. [0003] In the prior art, metal filter plates are mostly castings, and then shaped by machining. This kind of metal filter plate has complex structure, difficult processing, cast...
