Low-noise plastic production device convenient for raw material preheating

Abstract

The invention relates to the technical field of plastic processing equipment, and relates to a low-noise plastic production device convenient for raw material preheating. The low-noise plastic production device comprises a stock bin, a material conveying pipeline, a material weigher, a material mixer, a temporary stock bin, an extruder, a die surface hot-cutting granulator, a first cyclone separator, a second cyclone separator, a vibration sieve and a packaging machine which are sequentially connected, wherein pneumatic conveying systems are arranged among the die surface hot-cutting granulator, the first cyclone separator and the second cyclone separator, a pneumatic conveying system is also arranged between the vibration sieve and the packaging machine, and each pneumatic conveying system comprises a conveying fan, a connection tee and a conveying pipeline; a pipeline main body of the material conveying pipeline is constructed with a heating runner and a charge channel along an axial direction; a sound-isolation cover body is arranged at each conveying fan in a covering manner; and waste gas exhaust ports are arranged at the material mixer, the first cyclone separator and the second cyclone separator, and all the waste gas exhaust ports are connected with a spray tower. The low-noise plastic production device disclosed by the invention is convenient for conveying of plastic processing raw materials.

Description

Technical field [0001] The invention relates to the technical field of plastic processing equipment, in particular to a low-noise plastic production device that is convenient for preheating raw materials. Background technique [0002] Plastics are macromolecules (macromolecules), commonly known as plastics or resins, which are polymerized by monomers as raw materials through addition polymerization or polycondensation reactions. They can freely change their composition and shape. They are usually made of synthetic resin and It is composed of fillers, plasticizers, stabilizers, lubricants, pigments and other additives. When plastics are processed and produced (granulation), a series of operations such as mixing, hot cutting, and screening are required after mixing the raw materials for plastic preparation. [0003] In existing plastic production lines, silos are usually used to store a relatively large amount of plastic preparation materials and transport them to manufacturing equi...

AI Technical Summary

Problems solved by technology

Due to the characteristics of the raw materials for plastic preparation, the raw materials for plastic preparation cannot be extracted or transported at low temperature, which greatly affects the production efficiency

In addition, in the process of plastic processing and production (granulation), a large amount of heat and waste gas will be generated, and the existing plastic processing and production cannot better recycle or process the generated heat and waste gas.

In addition to the above, in the prior art, there is still a lack of a better delivery system, so that the prepared plastic semi-finished products can be better run between various equipment
