Technical Field

Background

The sticking of one or more layers of corrosion-resistant and wear-resistant rubber liners to metal equipment is a very effective method of protecting metal equipment from damage by corrosive or abrasive media. The method has been widely used in chemical industry, electric power condenser, water treatment equipment, ion exchange resin, etc. Many porous plates are arranged in the devices, and some devices have dozens or even hundreds of holes, the pore diameter of the porous plates is 35-45 mm before rubber lining, the thickness of the rubber lining is 3-5 mm, and the pore diameter of the rubber lining is 25-35 mm.

In addition, the method is only suitable for lining glue on a perforated plate with the steel plate thickness less than or equal to 30mm, and the perforated plate with larger thickness is difficult to blow the glue plate to a proper position in the hole completely. For the porous plate, the prior method is to vertically press the rubber on the porous plate by using a cylindrical cone head, push the rubber plate into the hole, squeeze the rubber plate contacted with the cone head into a hole shape, then cross-roll for at least 2 times, tightly press the rubber plate on the hole wall by using a press roller, and heat and press vulcanization in a vulcanizing tank after rubber lining is completed. Because the process is completely manual operation, the efficiency is low, and the defects of tilting, bubbling, delamination and the like of the rubber plate are easily caused by partial rolling in-place in the hole.

Therefore, it is necessary to develop a hole plate rubber lining tool to solve the above technical problems.
