Description

Technical Field

[0001] The utility model relates to the field of chemical production equipment, and more particularly, to a stirring device for producing flocculants. Background Art

[0002] Flocculants are commonly used chemical agents in the water treatment process. They coagulate suspended particles in water into larger flocs to facilitate subsequent sedimentation and filtration processes. In the production process of flocculants, the full mixing and reaction of raw materials are key steps to ensure product quality. As an important device to achieve this process, the performance of the stirring device directly affects production efficiency and product stability.

[0003] There are still some deficiencies in the prior art: Due to the characteristics of flocculant raw materials, heating and temperature control are required during stirring in the reaction kettle. Although some heating devices are provided in the existing reaction kettles, the heating effect of such heating devices is not ideal, such as slow heating by water bath. Moreover, the existing heating devices only have a heating function. When cooling is required at the end of the reaction or during the reaction process, simple natural heat dissipation is often used, which will affect the quality of the flocculant. Summary of the Utility Model

[0005] A stirring device for producing flocculants includes: a stirring shaft and stirring blades. The stirring shaft is rotatably installed in the reaction kettle. A stirring motor is installed at the center of the kettle cover of the reaction kettle, and the stirring motor drives the stirring shaft to rotate. Multiple layers of the stirring blades are fixed in the middle and lower part of the stirring shaft. A feeding pipe is provided on the kettle cover, and a discharging pipe is provided at the bottom of the reaction kettle. A temperature control device is further provided in the reaction kettle. The temperature control device is composed of a vertical pipe and a secondary pipe. The vertical pipe is vertically installed in the reaction kettle, and its upper and lower ends respectively penetrate through the kettle cover and the bottom plate of the reaction kettle. An inlet connector and an outlet connector are respectively provided at the upper and lower ends of the vertical pipe. The middle section of the vertical pipe is closed and not connected. The upper end of the secondary pipe is communicated with the upper section of the vertical pipe, and the lower end of the secondary pipe is communicated with the lower section of the vertical pipe. The secondary pipe is a serpentine pipe in the vertical direction, and the secondary pipe is located above and below the stirring blades and does not interfere with the rotation of the stirring blades.

[0006] Preferably, a plurality of rotating bearings are provided at the lower part of the stirring shaft. The rotating bearings are arranged between the stirring blades and above the stirring blades, and the rotating bearings are fixedly connected to the nearest section of the secondary pipe through fixing rods.

[0007] Preferably, the sections of the secondary pipe close to the vertical pipe are fastened to the vertical pipe through clamps.

[0008] Preferably, at least two vertical pipes are arranged in the reaction kettle, one of the vertical pipes is communicated with a heat source, and the other vertical pipe is communicated with a cold source.

[0009] Beneficial effects: A temperature control device is arranged in the reaction kettle of the device. The temperature control device is connected to a heat source and a cold source. When heating is required, the heat source is introduced, and when cooling is required, the cold source is introduced. Moreover, the serpentine auxiliary pipe can quickly exchange heat with the flocculant, and the rotation bearing and the clamp are arranged to ensure the stability of the auxiliary pipe during stirring.
