Abstract

The utility model discloses a stirring tank for chemical products, which belongs to the technical field of chemical equipment. The utility model provides a stirring kettle for chemical products which can make materials evenly stirred and whose rotating speed of a stirring shaft can be adjusted. Its structure includes a kettle body and a kettle cover. The kettle body and the kettle cover are connected by flanges. The stirring paddle and the stirring shaft are connected with the power output shaft of the motor, and it is characterized in that strip-shaped protrusions are arranged on the inner wall of the kettle, and a frequency converter is connected to the motor. This chemical product uses a stirring device to make the material mix more evenly and prevent the stirring shaft from breaking.

Description

Stirring tank for chemical products

technical field

The utility model relates to a stirring kettle for chemical products, which belongs to the technical field of chemical equipment.

Background technique

In chemical production operations, chemical raw materials are often stirred and mixed. The most common stirred tank for chemical products is a container or device with stirring, which is often used for stirring and mixing materials in chemical production. Ordinary stirred tanks are usually equipped with a set of flat paddles on a single stirring shaft to be stirred by a motor. The inner wall of the tank is usually smooth, which often causes uneven mixing of materials near the inner wall of the tank; and the ordinary stirred tank The stirring shaft usually rotates at a constant speed. When stirring materials with high viscosity, the starting speed of the motor is faster, but the material is relatively viscous, which often causes the rotation of the stirring shaft to be blocked, resulting in the breaking of the stirring shaft.

Contents of the invention

In order to overcome the above-mentioned defects in the prior art that the stirring tank stirs the material unevenly and the rotating speed of the stirring shaft is constant, the utility model provides a stirring tank for chemical products that can make the material stir evenly and the rotating speed of the stirring shaft can be adjusted.

The utility model is realized through the following technical solutions: a stirring kettle for chemical products, including a kettle body and a kettle cover, the kettle body and the kettle cover are connected by flanges, the kettle cover is provided with a feed port, and the lower end of the kettle body is provided with Outlet, a stirring shaft is provided in the kettle body, and a stirring paddle is arranged on the stirring shaft, and the stirring shaft is connected with the power output shaft of the motor. The connection is provided with a frequency converter.

The number of said strip-shaped protrusions is 4-8 pieces.

Compared with the prior art, the beneficial effect of the utility model is that the stirred tank for this kind of chemical products has a strip-shaped protrusion on the inner wall of the tank, which increases the contact area between the material and the inner wall of the tank, increases the friction coefficient, and makes the material The mixing is more uniform; the motor is connected with a frequency converter, so that the speed of the stirring shaft can be adjusted to prevent the stirring shaft from breaking.

In the figure, 1. Feed inlet, 2. Motor, 3. Frequency converter, 4. Kettle cover, 5. Kettle body, 6. Stirring shaft, 7. Stirring paddle, 8. Strip-shaped protrusion, 9. Discharge port .

Detailed ways

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figure 1, the stirred tank for this kind of chemical products includes a kettle body 5 and a kettle cover 4, which are connected by flanges. A discharge port 9 is provided, a stirring shaft 6 is arranged in the kettle body 5, and a stirring paddle 7 is arranged on the stirring shaft 6, and the stirring shaft 6 is connected with the power output shaft of the motor 2, and strips are arranged on the inner wall of the kettle body 5. Shaped protrusion 8 increases the contact area between the material and the inner wall of the kettle body 5, increases the friction coefficient, and makes the material mix more evenly; the motor 2 is connected with a frequency converter 3, so that the rotating speed of the stirring shaft 6 can be adjusted to prevent the stirring shaft from A break occurs.

The number of the strip-shaped protrusions 8 is 4-8 pieces, too many will reduce the space in the still body.
