Description

A stirring paddle of a high-speed mixer

technical field

The utility model relates to the technical field of stirring equipment, in particular to a stirring paddle of a high-speed mixer.

Background technique

Emulsion explosives are new products developed in the 1970s. With the rapid development of our country's economy, the continuous progress of chemical science and technology, and the continuous improvement of consumers' requirements for emulsion explosives, the quality of its production line is not only related to the own interests of the production enterprises, but more importantly, it is related to people's life safety , so its quality control is imperative. However, the production of products that meet the needs of customers is not directly put into production, but requires our inspectors to do a small test in the laboratory first. The key equipment for the test is the high-speed mixer, which uses high-speed shear to make the water phase and oil phase solution at a certain temperature. It is fully mixed and emulsified into a water-in-oil emulsion matrix, and the finished explosive is formed through sensitization. In the prior art, the high-speed mixer has only one fan blade at the bottom of the stirring shaft due to the single blade of the stirring blade. The solution in the container cannot be fully stirred, the mixing is uneven, and the matrix cannot achieve the emulsification effect, which has a great impact The experimental research results.

Utility model content

In order to solve the technical problems in the background technology, the utility model proposes a stirring paddle of a high-speed mixer, which has a good stirring effect.

The stirring paddle of a high-speed mixer proposed by the utility model includes a stirring shaft. From top to bottom, the stirring shaft is connected with a first blade group, a second blade group and a third blade group. The first blade group includes at least two The first blade is symmetrical to the axis of the stirring shaft and fixed to the stirring shaft. The second blade set includes at least two second blades that are symmetrical to the axis of the stirring shaft and fixed to the stirring shaft. The third blade set includes at least two blades that are fixed to the stirring shaft. The third blade is axially symmetrical and fixed to the stirring shaft; along the rotation direction of the stirring shaft, the first blade is inclined upward by 12°-18° and the second blade is inclined downward by 12°-18°, and the third blade is arranged horizontally.

Preferably, the third blade group is located at the bottom end of the stirring shaft.

Preferably, the connection between the second blade set and the stirring shaft is located between the connection between the first blade set and the stirring shaft and the bottom end of the stirring shaft.

Preferably, the inclination angle of the first blade is 15°.

Preferably, the inclination angle of the second blade is 15°.

Preferably, the first number of blades in the first blade group is equal to the second number of blades in the second blade group.

Preferably, the first blade set, the second blade set, and the third blade set respectively include two first blades, two second blades, and two third blades.

In the utility model, the first blade group, the second blade group and the third blade group are connected on the stirring shaft, and the above three groups of blade groups are stirred together to form a coordination effect to improve the stirring effect; the third blade group is located at the most The bottom and the third blade are arranged horizontally, so as to prevent sedimentation. Along the rotation direction of the stirring shaft, the second blade is inclined downward by 12°-18°. During the rotation of the stirring shaft, the second blade will be located below it At the same time, along the rotation direction of the stirring shaft, the first blade is inclined upwards by 12°-18°. During the rotation of the stirring shaft, the first blade will push the solution above it downward; therefore, the first blade The blade group, the second blade group and the third blade group have different motion trajectories, so that the solution has different flow directions, thereby improving the stirring effect.

Detailed ways

As shown in FIG. 1 , FIG. 1 is a schematic diagram of a stirring paddle of a high-speed mixer proposed by the present invention.

With reference to Fig. 1, the agitating paddle of a kind of high-speed mixer that the utility model proposes comprises agitating shaft 1, and from top to bottom, a first blade group, a second blade group and a third blade group are connected on the agitating shaft 1, the first One blade set includes two first blades 2 that are symmetrical to the stirring shaft 1 and fixed to the stirring shaft 1, and the second blade set includes two second blades 3 that are symmetrical to the stirring shaft 1 and fixed to the stirring shaft 1. The three-blade group includes two third blades 4 that are symmetrical to the axis of the stirring shaft 1 and fixed to the stirring shaft 1; along the rotation direction of the stirring shaft 1, the first blade 2 is inclined upward by 15° and the second blade 3 is inclined downward by 15°. The third blade 4 is arranged horizontally.

In the above-described embodiment, the first blade group, the second blade group and the third blade group are connected on the stirring shaft 1, and the above-mentioned three groups of blade groups are stirred together to form a coordination effect to improve the stirring effect; the third blade group Located at the bottom and the third blade 4 is arranged horizontally, so as to prevent precipitation. Along the direction of rotation of the stirring shaft 1, the second blade 3 is inclined downward by 15°. During the rotation of the stirring shaft 1, the second blade 3 will Push the solution below it upwards, and at the same time, along the rotation direction of the stirring shaft 1, the first blade 2 is inclined upward by 15°. During the rotation of the stirring shaft 1, the first blade 2 will push the solution above it downward; Therefore, the first blade set, the second blade set and the third blade set have different motion trajectories, so that the solutions have different flow directions, thereby improving the stirring effect.

In a further improved technical solution, the third blade group is located at the bottom of the stirring shaft 1, which can reduce the sediment generated during the stirring process.

In a further improved technical solution, the connection between the second blade set and the stirring shaft 1 is located between the connection between the first blade set and the stirring shaft 1 and the bottom end of the stirring shaft 1, so that the spatial distribution of water flow can be more reasonable.
