Abstract

The invention discloses a firework powder mixer which comprises a mixing mechanism and a feeding mechanism. The mixing mechanism comprises a mixing cylinder (21) and an explosion-free rotary cleaning device which is arranged in the mixing cylinder and comprises a rotating shaft (12), a hood (14) arranged at the lower end of the rotating shaft and a filter mesh (10) arranged at the upper end of the rotating shaft, and a mixing chamber (17) consists of the hood and the lower part of the mixing cylinder which is connected with the feeding mechanism and a suction pipe (4) through an air conveying mechanism. The invention has compact and simple structure, convenient mounting and detection and low manufacture cost. Under the vacuum negative pressure action of a pneumatic conveyer, powder materials can form a strong cascade which enters the mixing chamber to be suspended, rolled and mixed more evenly. The invention has improved mixing efficiency and mixing quality of the powder, good working stability, low energy consumption, safety and reliability, can realize the full automation of scale production and is beneficial to environmental protection.

Description

technical field

[0001] The invention relates to a mixer, in particular to a fireworks medicine mixer. Background technique

[0002] At present, fireworks drug mixing mainly includes manual mixing and mechanical equipment mixing, each of which has the following problems: First, artificial drug mixing not only has complicated operating procedures, low production efficiency, and low mixing quality; it also requires workers to operate with high proficiency and is dangerous The coefficient is high and the safety is low; at the same time, it cannot be applied to large-scale automated production; secondly, mechanical mixing not only has low mixing efficiency and slow speed, but also has many mechanical transmission frictions and hidden dangers, and there are certain dangers at the same time. Contents of the invention

[0003] Aiming at the problems existing in the mixing of fireworks and drugs in the prior art, the present invention provides a method that not only enables the dru...
