Description

Technical Field

[0001] The utility model relates to the field of cleaning the inner wall of a reaction kettle, in particular to an integrated device for stirring and cleaning a concrete expansion agent. Background Art

[0002] The production process of the expansion agent generally includes the following steps: 1. Add active aluminum powder, alkali metal silicate, organic surfactant, sodium carbonate and sodium sulfate into the reactor according to the formula ratio. 2. Add an appropriate amount of water, start stirring and react. The reaction temperature is generally controlled between 50-70 degrees Celsius. 3. After 30-60 minutes of reaction, add an appropriate amount of alumina powder and continue stirring the reaction. 4. Add stabilizers and regulators as needed and mix thoroughly.

[0003] In the above process, the expansion agent raw materials have a certain degree of adhesion after being mixed with water. After the raw materials are fully mixed, they need to be discharged. During discharge, the raw materials adhered to the inner wall of the reactor are not easy to be discharged under the action of gravity, resulting in waste. When adding cleaning liquid for cleaning, the impact effect of the cleaning liquid under the rotation of the agitator cannot effectively guarantee that the static adhesion materials can be discharged. The raw materials attached to the rotating parts are easy to clean because the rotation speed is suddenly increased and there is a large speed difference between them and the cleaning liquid. Therefore, for the cleaning of the inner wall of the reactor, an integrated equipment for mixing and cleaning concrete expansion agents is proposed. Utility Model Content

[0028] The rotary wiping mechanism that revolves along with the stirring unit 3 rotates on its own during the rotation process, and the self-rotating rotary wiping mechanism further improves the wiping efficiency of the rotary wiping mechanism.

[0029] In this embodiment: when stirring or cleaning is performed, by starting the stirring unit 3, the stirring unit 3 drives the rotating wiping mechanism to revolve, and the rotating wiping unit in the revolving state partially rotates under the driving action of the rotation component, which can better self-clean the inner wall of the kettle body 1.

[0030] Please refer to Figure 2 , Figure 3 and Figure 4 , the rotary wiping mechanism includes: a rotation component and a revolution component;

[0031] The revolution assembly includes a connecting piece 8 connected to the bottom of the stirrer of the stirring unit 3, a fixing column 9 is fixedly connected to the top of the crossbar of the connecting piece 8, and a gap exists between one end of the crossbar of the connecting piece 8 and the inner wall of the kettle body 1;

[0032] The center of the fixed column 9 is fixedly connected to the cross bar portion of the connecting piece 8, and the eccentric bottom end of the fixed column 9 is connected to a static cleaning rod 10, the bottom end of the static cleaning rod 10 is connected to a curved cleaning rod 11, the outer wall of the static cleaning rod 10 contacts the inner wall of the kettle body 1, and the outer wall of the curved cleaning rod 11 contacts the curved surface of the inner cavity of the kettle body 1.

[0033] In this embodiment: the driving motor in the stirring unit 3 is started, and the driving motor drives the spiral structure stirrer to rotate through the coupling. When the spiral stirrer rotates, the raw material of the expansion agent and the added water are fully stirred. At the same time, the stirrer drives the connecting member 8 to rotate, and the connecting member 8 drives the fixed column 9 to rotate with the stirrer as the axis. At the same time, the fixed column 9 drives the static cleaning rod 10 and the arc cleaning rod 11 to scrape the inner wall of the kettle body 1 to prevent the mixed viscous raw materials from adhering to the lower part of the inner wall of the kettle body 1, so that the stirrer can be better stirred;
