Description

A self-cleaning silo

technical field

The invention relates to an automatic cleaning bin.

Background technique

Plastic is a material with high molecular polymer as the main component. It is composed of synthetic resin and fillers, plasticizers, stabilizers, lubricants, colorants and other additives. It is in a fluid state during manufacturing and processing to facilitate modeling. , assumes a solid shape when processing is complete. The main component of plastic is synthetic resin. Resin was originally named after the lipids secreted by animals and plants, such as rosin, shellac, etc. Synthetic resin (sometimes directly referred to as "resin") refers to a high molecular polymer that has not been mixed with various additives. Plastic modification refers to changing the properties of plastic materials in the expected direction through physical, chemical or both methods, or reducing the cost significantly, or improving certain properties, or endowing the plastic with Material new functionality. The modification process can occur during the polymerization of synthetic resin, that is, chemical modification, such as copolymerization, grafting, crosslinking, etc., or it can be carried out during the processing of synthetic resin, that is, physical modification, such as filling, co- Mix, enhance, etc.

At present, the production process of modified plastics is as follows: 1. Ingredients, through automatic weight loss weighing scales, according to the product formula ratio, various raw and auxiliary materials are configured to ensure that the ratio of various raw and auxiliary materials meets the product formula requirements. 2. Melt extrusion, the material is automatically fed into the screw extruder through the weight loss scale, and the material is heated and sheared to melt and mix the mixture, mainly including material extrusion, melting, shear mixing, vacuuming, and shearing and other steps, so that various additives are uniformly dispersed in the polymer, and the polymer melt is extruded through the die hole of the extruder. 3. Cooling, using circulating water or air to cool the polymer melt extruded from the extruder into a solid state. 4. Air dry, dry the cooling water on the polymer strip. 5. Pelletizing: Pelletizing polymer strips to obtain plastic particles. 6. Sieve to remove plastic particles that do not meet the particle size requirements such as being too long or too short to obtain plastic particle products that meet the specified size. 7. Homogenization, the granular modified plastic body is sent to the homogenization bin for homogenization to ensure the uniformity of materials in each bin. 8. Packaging, pack the product according to the specified weight, and print the product name, grade, color number, weight and production batch number on the packaging bag.

Among them, before the material enters each process, the material will be transferred to the silo, so that the material will adhere to the inner wall of the silo. When producing another product, if it is not cleaned in time, it will be in the product. The addition of impurities affects the qualified rate of products and increases production costs.

At present, in the production process of modified plastics, the success rate of modified plastics is reduced due to incomplete cleaning of the bin body. When producing another product, it is necessary to clean the bin body to remove the remaining materials in the bin, which is of great importance to the production of new products. The materials and products are polluted, and the discharged cleaning liquid is easy to pollute the environment.
