Abstract
The invention relates to a vacuum spiral conveyor which comprises a spiral conveying shaft. The spiral conveying shaft is of a hollow structure and is internally provided with a vacuum pipe. Filtering holes are formed in the positions, between adjacent spiral blades, on the spiral conveying shaft. Filtering covers covering the filtering holes are arranged on the outer wall of the spiral conveying shaft. The diameter of filter holes of the filtering covers is smaller than the diameter of the filtering holes. The density of the filter holes of the filtering covers is smaller than the density of the filtering holes. Exhaust openings are formed in the positions, corresponding to the filtering holes, on the pipe wall of the vacuum pipe. The vacuum pipe is connected with a vacuum pump. According to the vacuum spiral conveyor, air is sucked in the conveying process, the amount of air entering a packaging bag is greatly reduced, the structure is simple, and use is convenient.
Description
Technical field
The present invention relates to package packing machine field, particularly to powder conveying apparatus.
Background technology
The material of powder body contains substantial amounts of air when entering feed box, and this admixture of gas is through auger (spiral
Carrier) be input to packaging bag after so that the actual fill capacity of packaging bag is greatly reduced to 30% about it is therefore necessary to
In hopper pumping unnecessary air with ensure feed auger conveying is out and out powder material.
Content of the invention
The problems referred to above existing for prior art, applicant is studied and is improved, and provides a kind of vacuum screw conveying
Device.
In order to solve the above problems, the present invention adopts following scheme：
A kind of vacuum screw carrier, including screw conveyor shaft, described screw conveyor shaft is hollow structure, is built-in with vacuum
Pipe, between adjoining spiral blade, screw conveyor shaft is provided with filtering holes, and the outer wall of screw conveyor shaft is provided with the described filtering holes of covering
Filter mantle, the filter opening diameter of described filter mantle is less than the diameter of described filtering holes, and the filter opening density of described filter mantle is less than institute
State the density of filtering holes；It is provided with bleeding point, vacuum tube and vacuum pump with described filtering holes corresponding position on the tube wall of described vacuum tube
It is connected.
The method have technical effect that：
The present invention extracts air using in course of conveying, substantially reduces the air capacity entering packaging bag, and structure is simple, uses
Convenient.
Brief description
Fig. 1 is the structural representation of the present invention.
In figure：1st, screw conveyor shaft；2nd, vacuum tube；3rd, helical blade；4th, filtering holes；5th, bleeding point；6th, filter mantle.
Specific embodiment
Below in conjunction with the accompanying drawings the specific embodiment of the present invention is described further.
As shown in figure 1, the vacuum screw carrier of the present embodiment, including screw conveyor shaft 1, screw conveyor shaft 1 is hollow
Structure, is built-in with vacuum tube 2, and between adjoining spiral blade 3, screw conveyor shaft 1 is provided with filtering holes 4, outside screw conveyor shaft 1
Wall is provided with the filter mantle 6 covering filtering holes 4, and the filter opening diameter of filter mantle 6 is less than the diameter of filtering holes 4, and the filter opening of filter mantle 6 is close
Degree is less than the density of filtering holes 4；It is provided with bleeding point 5, vacuum tube 2 and vacuum pump with filtering holes 4 corresponding position on the tube wall of vacuum tube 2
It is connected.When conveying powder, vacuum pump work, the inside evacuation to screw conveyor shaft 1, form negative pressure, powder carry process
In, most air are absorbed, thus avoiding in air input packaging bag.In the present invention, due to the setting of filter mantle 6, can
Avoid the blocking of filtering holes 4 completely, it is to avoid vacuum failure phenomenon occurs.
Embodiment provided above is the better embodiment of the present invention, is only used for the convenient explanation present invention, not to this
Bright make any pro forma restriction, any those of ordinary skill in the art, if without departing from the carried skill of the present invention
In the range of art feature, using the Equivalent embodiments locally changed done by disclosed technology contents or modify, and
Without departing from the technical characteristic content of the present invention, all still fall within the range of the technology of the present invention feature.
