Drawings
FIG. 1 is a schematic structural view of a negative pressure feeding device according to the present invention;
the figure is as follows: 1. a suction pipeline; 101. a feed inlet; 102. a discharge port; 2. an air supply device; 3. a guide tube; 4. a storage bin; 5. a delivery hose.
Detailed Description
The present invention will be further described with reference to the accompanying drawings and the detailed description, and it should be noted that any combination of the embodiments or technical features described below can be used to form a new embodiment without conflict.
As shown in FIG. 1, the present application discloses a negative pressure feeding device, comprising
One end of the material suction pipeline 1 is provided with a feeding hole 101, and the other end is provided with a discharging hole 102;
During the use, air supply arrangement 2 pours the air into in inhaling material pipeline 1 to make inhaling material pipeline 1 and producing the air current that flows to discharge gate 102 by feed inlet 101, at this moment, feed inlet 101 department will form the negative pressure in order to absorb the material like powder etc. the material will be sent into air current under air supply arrangement 2 after inhaling in inhaling material pipeline 1 and will move towards discharge gate 102 direction, in order to carry the material.
According to the air supply device, the air supply device 2 is matched with the material suction pipeline 1, so that negative pressure can be formed at the feeding hole 101 to suck materials, and the materials are conveyed to the discharging end through air flow, the working efficiency is high, and the labor cost is low; meanwhile, the air supply device 2 is arranged outside the material suction pipeline 1 instead of in the material suction pipeline 1 and is communicated with the material suction pipeline 1 through an air supply end, so that when the air supply device 2 injects air flow into the material suction pipeline 1, powder materials enter the air supply device 2, and the air supply device 2 is damaged. The air supply device 2 in the application can adopt a vortex fan or other fans.
Preferably, inhale material pipeline 1 and be the setting of loudspeaker form in this application, just inhale material pipeline 1's diameter by feed inlet 101 one end orientation discharge gate 102 one end reduces gradually, adopts such mode of setting up to strengthen and inhale material pipeline 1 interior gas flow velocity to improve feed inlet 101's suction, in order to conveniently inhale material pipeline 1 with the material.
Preferably, still be provided with stand pipe 3 in the material pipeline 1, the one end of stand pipe 3 install in feed inlet 101, the other end orientation discharge gate 102, stand pipe 3 with the inner wall of material pipeline 1 encloses into a cavity, air supply arrangement 2 with the cavity intercommunication, the cavity orientation discharge gate 102 one side seted up the air outlet.
Because inhale in this application material pipeline 1's diameter by feed inlet 101 one end orientation discharge gate 102 one end dwindles gradually, so stand pipe 3 with inhale material pipeline 1's inner wall and enclose into a cavity and be big-end-up's shape down, the gas that air supply arrangement 2 sent into is after getting into the cavity, removes to cavity upper portion extrusion, its velocity of flow will accelerate to can improve feed inlet 101's suction, conveniently inhale the material with the material and inhale the material pipe in, simultaneously, the stand pipe 3 of setting can block the material, avoid the material to flow back to air supply arrangement 2 in.
