Embodiment 1

[0033] First of all, it needs to be explained that the working environment in this implementation is for the acetylene generator.

[0034] About the acetylene generator, it is a device that can make water and calcium carbide react chemically to generate acetylene gas under a certain pressure. It can produce acetylene by fully reacting water and calcium carbide in a closed space.

[0035] This embodiment discloses a stirring mechanism of a long-life acetylene generator, which includes a rotating shaft, a rotating arm, stirring teeth 4, a positioning mechanism and a baffle plate 1, the rotating shaft passes through the baffle plate 1, the rotating shaft is perpendicular to the rotating arm, and rotates The shaft is connected to the rotating arm through the positioning sub-mechanism, and the rotating arm is connected to a plurality of stirring teeth 4; the rotating arm has a hollow structure, and the rotating arm can isolate the hollow structure from the surrounding environment to...

Embodiment 2

[0056] Embodiment 2 discloses a long-life acetylene generator stirring mechanism and its working method, comprising the following steps:

[0057] Step 1: Assemble the stirring mechanism of the long-life acetylene generator as described in Example 1. First weld the stirring tooth 4 on the rotating arm, weld the rotating arm on the clamp 9, then weld the horizontal reinforcing plate 5 and the vertical reinforcing plate 6, weld the blocking plate 2 at the pipe end of the rotating arm to block the rotating arm, Then a pair of hoops 9 are installed on the stirring shaft 7 through 12 high-strength bolts 8, and finally high-strength screws 10 are installed.

[0058] Step 2: The power source 12 drives the stirring shaft 7 to rotate at a certain speed, and the stirring teeth 4 repeatedly stir the calcium carbide on the retaining plate, so that the reaction surface of the calcium carbide is continuously updated, fully contacted and reacted with water, and the residual calcium carbide is...

Abstract

The invention discloses a life acetylene generator stirring mechanism and method. The life acetylene generator stirring mechanism comprises a rotating shaft, a rotating arm, a plurality of stirring teeth, a positioning sub-mechanism and a retaining disc. The rotating shaft penetrates through the retaining disc, the rotating shaft is perpendicular to the rotating arm, and the rotating shaft is connected with the rotating arm through the positioning sub-mechanism, and the rotating arm is connected to the stirring teeth; the rotating arm is of a hollow structure, and the rotating arm can isolatethe hollow structure from the surrounding environment to increase buoyancy; and the retaining disc is mounted on the lower parts of the rotating arm and the stirring teeth. The service time of the stirring mechanism is prolonged.

Description

technical field [0001] The invention relates to the field of chemical equipment, in particular to a long-life acetylene generator stirring mechanism and method. Background technique [0002] In the traditional calcium carbide acetylene generator, the rotating arm of the stirring mechanism is generally a channel steel structure, and the Q235 cuboid steel plate is welded at a certain angle at the lower part of the channel steel as the stirring tooth. During operation, in order to avoid the deformation of the rotating arm by calcium carbide Or broken, there is a connecting brace between the middle of the rotating arm and the stirring shaft. In use, the brace is often deformed, and the rotating arm and the clamp are broken. The actual service life is only 3-6 months. Maintenance Frequent replacement has a great impact on production safety. [0003] The inventor believes that the main reason for this phenomenon is that, firstly, the rotating arm of the stirring mechanism is made...
