Problems solved by technology

The devices used in this industry to evenly distribute reinforcing particles into composite materials are generally: mechanical screw conveying method; pressure vessel conveying method; direct insertion method, etc., but these methods all exist: adding reinforced particles The amount is not easy to control and is unevenly distributed in the composite material, because the feeding amount is accompanied by periodic pulsation of the mechanical device, resulting in uneven addition amount. On the other hand, the reinforcement particles are added manually into the device, which is It is also an importan

Embodiment 1

[0013] Referring to the accompanying drawings, the spherical cavity 2 is connected with the inlet pipe 3 and the outlet pipe 2 on the same axis, the ratio of the diameter of the inlet pipe 3 to the diameter of the outlet pipe 1 is 1:1.3, and there is a gap of 1 mm between the inlet pipe 3 and the outlet pipe 1 , The spherical cavity 2 is also provided with a feeding tube 4 .

Embodiment 2

[0015] Referring to the accompanying drawings, the elliptical cavity 2 is connected with the inlet pipe 3 and the outlet pipe 1 on the same axis, the ratio of the diameter of the inlet pipe 3 to the diameter of the outlet pipe 1 is 1:3, and there is 2mm between the inlet pipe 3 and the outlet pipe 1 The gap, the elliptical cavity is also provided with a delivery pipe 4.

[0016] When the present invention is in use, the inlet pipe 3 is connected with high-pressure gas with a pressure ranging from 1.5MPa to 5MPa, the outlet pipe 1 is connected with an atomizing nozzle, and the end of the feeding pipe 4 is directly inserted into the reinforced particles. The working principle is to use a certain air pressure The conveying gas enters the cavity 2 from the inlet pipe 3. When the conveying gas of a certain pressure passes through the cavity 2 quickly, a negative pressure will be formed in the cavity 2, so that the reinforced particles will automatically flow from the conveying pipe ...

Abstract

An automatic reinforcing particles feeder for spray deposition features that the coaxial inlet tube and outlet tube and the material delivering tubes are arranged in a cavity, and the diameter of inlet tube is less than that of outlet tube.

Description

technical field [0001] The present invention relates to an automatic particle adding device, in particular to a device for controllably transporting reinforcing particles to the vicinity of the nozzle in spray deposition, so that the atomized metal particles can be captured evenly and efficiently, so that the reinforcing particles can be used in the prepared Automatic feeding device for evenly distributed reinforcing particles in the composite. Background technique [0002] In the preparation of composite materials by spray deposition, it is necessary to uniformly distribute the reinforcing particles in a certain proportion in the prepared composite materials. The devices used in this industry to evenly distribute reinforcing particles into composite materials are generally: mechanical screw conveying method; pressure vessel conveying method; direct insertion method, etc., but these methods all exist: adding reinforced particles The amount is not easy to con...
