Hot-melting and feeding equipment for PVC pipe production raw materials

Abstract

The invention discloses hot-melting and feeding equipment for PVC pipe production raw materials, and relates to the field of PVC pipes. The equipment comprises a main supporting plate, the bottom surface of the main supporting plate is vertically and downwards welded with an extension vertical rod, the bottom end of the extension vertical rod is vertically sleeved with a bottom sleeve rod, the bottom surface of the bottom sleeve rod is horizontally and fixedly bonded with a rubber cushion plate, an outer supporting box is vertically connected to the top surface of the main supporting plate through bolts, a control panel is embedded in one side edge of the outer supporting box, feeding hoppers are symmetrically welded to the two side edges of the outer supporting box, outer box bodies are vertically and symmetrically connected to the two side edges of the outer supporting box through bolts, and a top fixing box is connected to the top surface of the outer supporting box through bolts. According to the equipment, the design is integrated, the structure is simple, operation is convenient, heating is uniform and stable without overflowing under the condition that multiple heating and heat preservation structures are adopted, the use efficiency of heat energy is greatly improved, and meanwhile, the scraping and cleaning effects are achieved while stirring is achieved through a spiral structure.

Description

technical field [0001] The invention relates to the technical field of PVC pipes, in particular to a hot-melt feeding device for PVC pipe production raw materials. Background technique [0002] PVC pipe (divided into PVC-U pipe, PVC-M pipe and PVC-O pipe) Rigid polyvinyl chloride pipe is made of polyvinyl chloride resin, stabilizer, lubricant, etc. and then extruded by hot pressing. The first plastic pipe to be developed and applied. PVC-U pipe has strong corrosion resistance, easy bonding, low price, and hard texture. However, due to the leakage of PVC-U monomer and additives, it is only suitable for water supply systems with a delivery temperature not exceeding 45°C. Plastic piping is used in applications for drainage, waste water, chemicals, heating and cooling fluids, food, ultrapure liquids, slurries, gases, compressed air and vacuum systems. [0003] For the production of the current PVC pipe, it is necessary to process the raw materials in advance and put them into ...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a PVC pipe production raw material hot-melt feeding equipment, to solve the traditional problem proposed in the above background technology is to use a fixed structure so that it is fixed on the designated equipment, which is not conducive to replacement and conversion to other equipment. The use of advanced equipment, and the lack of adjustment structure brings a lot of inconvenience to use. The current feeding and feeding equipment uses single-channel heating to heat it, and then puts the raw materials into the equipment through the funnel, so that the heat The melted raw materials will adhere to the inside of the feeding equipment, which will affect the use of the next hot-melt feeding process, making it unfavorable to the current production needs, and the natural falling feeding method makes feeding slow and incomplete, which greatly reduces production efficiency problem
