As shown in fig. 1 to 4, the device for recycling materials by using an airflow field provided by the invention comprises a main body 1, an air inlet pipe 2, a communicating piece 3 and at least two feeding pipes 4, wherein a discharge hole 5 is formed in the bottom of the main body 1, the air inlet pipe 2 is arranged at the top of the main body 1, the feeding pipes 4 are arranged on the side wall of the main body 1, the communicating piece 3 is positioned in the main body 1 and is communicated with the air inlet pipe 2, the side wall of the communicating piece 3 is provided with an air outlet which is inclined downwards, the air inlet pipe 2 is used for externally connecting a negative pressure air source and inputting the negative pressure air of the negative pressure air source into the main body 1 through the air outlet of the communicating piece 3, and the feeding pipes 4 are used for sucking the materials into the main body 1 under the action of the negative pressure air so that the materials leave the main body 1 through the discharge hole 5 under the action of gravity.
The device is used as follows:
A. the air inlet pipe 2 is connected with a negative pressure air source, the feeding pipe 4 is connected with a container filled with materials, and the discharging hole 5 is connected with a device for recycling the materials;
B. starting a negative pressure air source, and inputting negative pressure air to the air inlet pipe 2 through the negative pressure air source so that the negative pressure air forms a uniform air flow field in the main body 1;

D. the material leaves the body 1 through the outlet 5 and falls into the device for recycling the material.
Specifically, the invention adopts the communicating piece 3 to split the negative pressure gas so as to generate uniform airflow field after a plurality of negative pressure gases enter the main body 1, specifically, the flow directions of the gases in the main body 1 tend to be parallel to each other, so that the materials only receive vertical upward force of the negative pressure gases after entering the main body 1 through the feeding pipe 4, namely, the resultant force between the gravity of the materials and the acting force of the gases on the materials is vertical downward, and the materials can fall down and fall into the device for recycling the materials from the discharging hole 5, thereby ensuring that the phenomena of material back suction and material clamping can not occur.
In this embodiment, the number of the feeding pipes 4 is three, and the three feeding pipes 4 are distributed on the side wall of the main body 1 in a ring array with the central axis of the main body 1 as the center; the communicating piece 3 comprises a body 31, an air inlet part 32 and three air outlet parts 33, wherein the air inlet part 32 is arranged at the top of the body 31, the three air outlet parts 33 are obliquely arranged at the bottom of the body 31, the air inlet part 32 is communicated with the air inlet pipe 2, and the three air outlet parts 33 are communicated with the three feeding pipes 4 through the main body 1 in one-to-one correspondence.

B1. the negative pressure air source inputs negative pressure air into the air inlet pipe 2;
B2. negative pressure gas enters the communicating piece 3 through the air inlet pipe 2 and uniformly flows into the main body 1 from three air outlets of the communicating piece 3, so that the air pressure in the main body 1 is lower than the atmospheric pressure to suck materials into the main body 1.
Because the three air outlet portions 33 are all inclined downward, the negative pressure air mainly acts to suck materials and air into the main body 1 from the container, so that the sucked air also moves obliquely upward, and after a plurality of air streams collide with each other, the flow in the horizontal direction can be counteracted, so that the air forms a uniform air flow field, that is, the materials can not move randomly under the action of turbulent flow, and the reliable falling of the materials can be ensured. After the actual measurement, when the number of the feeding pipes 4 is three, the gas can be most stably offset.
In this embodiment, a funnel portion 11 is disposed between the main body 1 and the discharge port 5, and the funnel portion 11 is used for guiding the material to slide toward the discharge port 5. That is, when the material falls under the action of the resultant force between the gravity and the acting force of the air flow, the material falls on the funnel part 11, and then is guided by the funnel part 11 to move towards the discharge hole 5 in the middle, so that the material is further ensured to leave the main body 1 reliably, and the recovery is prevented from being influenced by the residual material in the main body 1.
