A plastic central feeding system

Abstract

The invention relates to the technical field of plastic production, in particular to a plastic central supply system which comprises control tables, vacuum breaker valves, Roots blowers, dust removalbarrels, a dust removing electromagnetic valve, a manual throwing box, a drying machine, a material position switch, a motor, a smashing device, a vacuum hopper, a first wind check valve, a crusher, aproportional valve, a material position switch, a plastic forming machine, a second wind check valve and an electric eye hopper. The number of the control tables, the vacuum breaker valves, the Rootsblowers and the dust removal barrels is two. The two vacuum breaker valves are fixedly connected to the output ends of the two Roots blowers. The crusher can crush plastic, crushed materials and rawmaterials manually added to the manual throwing box are conveyed to the vacuum hopper pneumatically through the proportional valve according to the proportion, and then placed down to the drying machine, after the crushed materials are heated, dehumidified and dried, similarly, the raw materials are conveyed into the plastic forming machine through a pneumatic conveying manner, time and labor aresaved, operation is convenient, and the production efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of plastic production, in particular to a plastic central feeding system. Background technique [0002] The method of pneumatically conveying materials has been applied in engineering as early as the 19th century, but it is mainly used for grain transportation in ports and factories. It is not widely used in industrial production, especially in chemical production. Since the end of the 20th century, due to The processing and application fields of PVC continue to expand, and the market scale continues to expand, thus promoting the rapid development of the PVC industry. The PVC production has a large-scale and intensive trend, the scale of the device is rapidly expanding, and the packaging method of small silos and packaging while producing Gradually replaced by large silos, remote conveying, and automatic packaging, pneumatic conveying technology has also been more and more applied in PVC production.
