Description

Vacuum feeding device

Technical Field

The utility model relates to an industrial hemp draws system brilliant technical field, specifically is a vacuum loading attachment.

Background

The industrial hemp refers to the hemp with the tetrahydrocannabinol content of less than 0.3 percent, the industrial hemp is called China hemp, is a 1-year herbaceous plant in the cannabis of the cannabinaceae, is divided into the industrial hemp and drug hemp, the hemp widely applied at home and abroad at present is the industrial hemp, the industrial hemp which is legally planted is a variety with low toxicity, and the THC value is less than 0.3 percent. The industrial hemp is not considered to have drug utilization value, but is still treasure on the whole body, the industrial hemp is mainly applied to the aspects of agricultural planting, spinning, clothes, paper making, military needs, chemical industry, novel building materials, biological energy sources, food health care, medicines, feeds and the like, the industrial hemp is used as economic crops cultivated in mountain generations such as the Yi nationality, the Miao nationality, the Yao nationality and the like, has a special status in the minority of the Yunnan nationality, the Yunnan is the only province which allows and supervises the industrial hemp planting in a regulation form up to now, according to the national agricultural statistics of the annual identification and the grain and agriculture organization of the United nations, china is the country with the largest planting area of the industrial hemp, the planting area occupies about half of the world, the industrial hemp needs to be conveyed to complete feeding in the crystal extraction and crystal preparation process of the industrial hemp, the manpower efficiency is lower, so the vacuum conveying is mostly adopted at present, but the vacuum feeding machine can reduce the labor intensity of manpower and improve the working efficiency, and is the first choice of most of powder material conveying modes;

the application number is CN202022481245.4, a vacuum feeder, when the apparatus takes place to block up in the dust filter, the electrical machinery drives the said rotating rod to rotate, in order to drive the brush to contact the said dust filter, sweep away the powder absorbed on the dust filter, the back flushing device blows the powder on the dust filter away from the dust filter, the dust filter does not need to dismantle and wash, avoid producing the dust, raise production efficiency;

although the device can sweep away the last adsorbed powder of dirt filtrating cover, the dirt filtrating cover need not the dismouting and washs, avoid producing the dust, the device is the same with traditional vacuum feeding machine, because industrial hemp is under vacuum feeding machine effect, material such as leaf splashes the dust and is inhaled in the pipeline in the feed bin is inside easily, directly lead to the pipe blockage, even present partial feeding machine has set up filter screen or other filter equipment, but this type of device is all installed inside the pipeline, can't judge whether filter equipment needs to be changed, in case pile up in the course of the work to jam clearance and trouble after, need open feed bin inspection and maintenance, the operation is inconvenient, and switch closed feed bin for a long time, can influence the gas tightness of feed bin, make later stage material loading efficiency reduce, in order better to avoid industrial hemp to draw the brilliant in-process vacuum feeding equipment jam of system, and for more conveniently change filter equipment, make the whole equipment gas tightness remain good state all the time. In view of this, we propose a vacuum charging device.
