Problems solved by technology

The more uniform the two are mixed, the better the product quality, but at the same time the higher the risk of explosion, it is the most important and dangerous process in the entire production process
However, in this method, during the mixing process, the friction between the drug and the screen and other components, as well as the moving parts of the equipment itself, is intense, and local high temperatures are easily generated, resulting in explosions.

Embodiment Construction

[0023] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention.

[0024] see figure 1 , is a structural schematic diagram of the pyrotechnic powder automatic mixing system provided by the present invention.

[0025] The pyrotechnic powder automatic mixing system 1 includes a mixing unit 11, an oxidant feeding unit 12, a reducing agent feeding unit 13, a collection unit 14, a packaging line 15, a control box 16, a manhole 17, a sewage pipe 18 and a grounding wire 19.

[0026] The mixing unit 11 includes a mixing chamber 111 , a blower 112 and a nozzle 113 . One end of the four nozzles 113 runs through the bottom of the mixing chamber 111 , and the other end is connected to the air blower 112 by pipes. The four nozzles 113 are eve...

Abstract

The invention provides an automatic pyrotechnic composition mixing system. The automatic pyrotechnic composition mixing system comprises an oxidant feeding unit, a reducing agent feeding unit, a mixing unit and a collecting unit; the mixing unit comprises a mixing cavity, an air blower and nozzles; one end of each of the plurality of nozzles penetrates through the bottom of the mixing cavity and the other ends of the nozzles are connected with the air blower through pipelines; the oxidant feeding unit and the reducing agent feeding unit are arranged on the two sides of the mixing cavity respectively; and the collecting unit is arranged at the top of the mixing cavity. With the adoption of the automatic pyrotechnic composition mixing system provided by the invention, the technical problems of a pyrotechnic composition mixing manner in the prior art that dangers are relatively great and explosion is easy to occur are solved.

Description

technical field [0001] The invention relates to the field of mixing equipment, in particular to an automatic mixing system for pyrotechnic powder. Background technique [0002] In the production process of fireworks and firecrackers, it is necessary to uniformly mix oxidizing agents and reducing agents to obtain finished pyrotechnics. The more uniform the two are mixed, the better the product quality, but at the same time the higher the risk of explosion, which is the most important and dangerous process in the entire production process. [0003] No matter the mixing method in the prior art is artificial mixing or mechanical mixing, the medicine is passed through the sieve by vibration or tumbling to complete the mixing. However, in this method, during the mixing process, the friction between the drug and the screen and other components, as well as the moving parts of the equipment itself, is intense, and local high temperatures are easily generated, resulting in explosions...
