Problems solved by technology

The convection drying method takes a long time to dry, and in its specific implementation, an adsorption dryer composed of molecular sieves is often used to dry using the temperature difference between dry and wet; the refrigeration system used in the freeze drying method is huge and consumes a lot of energy; the vacuum drying method cannot Quickly increase the dryness inside the raw material
The above drying process can only make the dryness of plastic particles reach about 3 / 10000 to 6 / 10000, and it is difficult to improve it.

Embodiment Construction

[0023] In order to make the above objects, features and advantages of the present invention more comprehensible, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0024] refer to figure 1 , shows a schematic structural view of an embodiment of a particle drying device of the present invention.

[0025] The device comprises a heating barrel 22, a vacuum barrel 15, a vacuum device, a raw material barrel 33, a heating device, and a heating device is arranged outside the heating barrel 22 to heat the heating barrel. The feed port of barrel 15 is connected. After the particulate matter is heated in the heating barrel, the particulate matter is subjected to vacuum treatment, and the dryness of the heated and vacuum-treated particulate matter can reach an ideal drying degree. All be provided with control valve at the feeding port of described heating bucket 22, vacuum bucket 15, reserve bucket 2...

Abstract

The invention provides a particle drying device. The drying device comprises a heating charging basket 22, a vacuum charging basket 15, a vacuum device, a reserve charging basket 24 and a heating device, wherein the outside of the heating charging basket 22 is provided with the heating device for heating the heating charging basket, and the discharge hole of the heating charging basket 22 is connected with the charge hole of the vacuum charging basket 15. The beneficial effect of the invention is as follows: the discharge hole of the heating charging basket 22 is connected with the charge hole of the vacuum charging basket 15 through a pipeline so that particles to be dried firstly pass through the heating charging basket for heating and then pass through the vacuum charging basket for vacuum treatment to obtain particles with ideal degree of drying.

Description

technical field [0001] The invention relates to the field of drying, in particular to a particle drying device. Background technique [0002] Plastic packaging products have high requirements on the dryness of plastic particle raw materials, especially in the production of some high-end plastic packaging products. When the water content of raw materials exceeds 0.012%, the hydrocarbons in the product are unstable and the volatile substances exceed the standard. The products produced cannot meet the requirements of use, which requires that the plastic particles need to be dried in advance during production. [0003] At present, there are many ways to dry granular materials, such as the commonly used convection drying method, freeze drying method, vacuum drying method and so on. The convection drying method takes a long time to dry, and in its specific implementation, an adsorption dryer composed of molecular sieves is often used to dry using the temperature difference betwee...
