Description

Automatic cleaning and sucking device for polyester-nylon composite production line Technical Field The utility model relates to the field of monomer suction, in particular to an automatic cleaning and sucking device for a polyester-nylon composite production line. Background At present, the existing polyester-nylon composite production process needs to add monomers to facilitate spinning production, and the redundant monomers are provided with water pumping equipment to pump away the redundant monomers. Because the water pumping equipment is inside the spinning production equipment, the casing of the pumping equipment is blocked by a monomer after long-time production, the quality of products is affected, if the equipment is cleaned after the equipment is stopped, the equipment is stopped for cleaning every 5 days according to the use experience, otherwise, the quality of the products is seriously affected, and the cost is wasted. The main characteristic of the structure of the suction device in the prior art is that when the single body is backlogged, the blockage phenomenon of the suction hood or the suction column can be caused, and on-site staff cannot clean the suction device when the suction device runs. Therefore, the temperature of the spinneret plate is too high in the production process, the product quality is affected, and if equipment is stopped for cleaning, a large amount of waste silk is caused, so that the cost is wasted. Disclosure of utility model The utility model aims to overcome the defects in the prior art, and provides an automatic cleaning and sucking device for a polyester-nylon composite production line, which solves the problem of single blockage of sucking equipment.
