Chemical mixer structure and installation steps

Chemical mixer is a kind of equipment in the chemical industry. Some chemical raw materials need to be stirred before they can be used normally. This is the role of chemical mixer. At present, many fields can be used, so what is the structure of chemical mixer? Today Xiaobian detailed introduction of "chemical mixer structure and installation steps."

1、 Structure of chemical mixer

1. Mixing vessel

According to the production scale, mixing purpose and material characteristics, the shape of mixing container is determined. If there is no special need, the vertical drum container is generally selected, and the appropriate height diameter ratio is determined; if there is a heating or cooling requirement, the jacket structure must be set outside the kettle.

2. Agitator

Ensure the effective mixing of materials; consume the least power; the lowest cost; easy to operate; easy to maintain; 3The mixing shaft should have enough torsion strength and bending strength. Generally, the mixing shaft should be rigid enough, and the rotation speed should be avoided between 800-1200 R / min. if the rotation speed is within this range, the mixing shaft should be flexible.

4. Mixing plant internals

According to the type of agitator. Material operating characteristics determine whether baffles and internal cooling tubes are required. If baffle is needed, low viscosity liquid is usually operated under the condition of full baffle （4 baffles, the width is 1 / 12 ~ 1 / 10 of the diameter of mixing vessel）； with the increase of viscosity, the baffle width becomes narrow, and it is unnecessary to set baffle for high viscosity liquid.

5. Shaft seal

If more liquid leakage is allowed. When the pressure in the kettle is low, the packing seal can be selected; when the leakage is allowed to be less. When the pressure or vacuum in the kettle is high and the friction power consumption between the shaft and the shaft sleeve is low, the mechanical seal should be selected; when the stirring medium is highly toxic. Flammable. For explosive or expensive high-purity materials, or when operating in high vacuum, magnetic drive device can be selected, but the efficiency of magnetic drive is very low.

6. Transmission

It meets the requirements of power and speed, reliable operation, convenient maintenance, high mechanical efficiency and low noise.

7. Rack

The mixing shaft should have enough support space to ensure that the deviation of the mixing shaft is small and the output shaft of the transmission is stable. Mixing shaft. Shaft seal device alignment; enough radial and axial bearing force.

2、 Installation of chemical mixer

1. It should be installed on the horizontal concrete foundation and fixed with anchor bolts.

2. Pay attention to the perpendicularity between the main body and the horizontal when installing.

3. After installation, check whether the bolts of each part are loose and whether the main engine compartment door is tight. If so, please tighten it.

4. Configure the power line and control switch according to the power of the equipment.

5. After the inspection, the no-load test run can be carried out, and the production can be started when the test run is normal.
