Description

Technical Field

[0001] The utility model relates to the technical field of production equipment for raw materials of cement grinding aids, and particularly relates to a stirring device for producing raw materials of sulfonate copolymer cement grinding aids. Background Art

[0002] The raw materials of sulfonate copolymer cement grinding aids are raw materials for producing cement grinding aids, which are recorded in the patent document with the publication number of CN 105152563 B and the main title of "A Kind of Raw Materials of Sulfonate Cement Grinding Aids and Its Preparation Method". In the production process of this kind of raw materials, stirring equipment is needed to stir components such as urea and water evenly. However, since urea is a white crystal, it sinks to the bottom of the equipment after being poured into the stirring equipment, and it takes a relatively long time to stir evenly, resulting in low production efficiency. Content of the Utility Model

[0003] In order to make up for the defects of the prior art, the utility model provides a stirring device for producing raw materials of sulfonate copolymer cement grinding aids with high stirring efficiency.

[0004] The utility model is realized by the following technical scheme:

[0005] A stirring device for producing raw materials of sulfonate copolymer cement grinding aids, including a tank body. A stirring motor is arranged at the upper end of the tank body. A rotating shaft is fixedly arranged at the output end of the stirring motor. After the rotating shaft extends into the tank body, a stirring shaft is connected to the rotating shaft through a key. Upper stirring wings are arranged on the stirring shaft, and the stirring shaft can move up and down relative to the rotating shaft; A cylinder is arranged at the lower end of the tank body. A fixed shaft is arranged at the output end of the cylinder. The fixed shaft extends into the tank body and is in sealed sliding connection with the tank body. The upper end of the fixed shaft contacts the stirring shaft. A filter screen is arranged on the fixed shaft, and the periphery of the filter screen is in sliding connection with the inner wall of the tank body.

[0006] The lower end of the fixed shaft is rotatably connected to the output end of the cylinder, the upper end of the fixed shaft is fixedly connected to the stirring shaft, and lower stirring wings are arranged on the fixed shaft.

[0007] A circular groove is formed on the fixed shaft, and a sleeve is sleeved on the circular groove. The filter screen is fixed on the sleeve.

[0008] The stirring shaft and the fixed shaft are connected through a ball hinge.

[0009] The beneficial effects of the utility model are:

[0010] The utility model is provided with a filter screen that can move up and down in the tank body. During the stirring process, the filter screen can move up and down driven by a cylinder, so as to lift the urea accumulated on the filter screen. After the filter screen descends, the urea leaves the filter screen driven by the speed difference and slowly falls. During the falling process, it is stirred and mixed evenly by the stirring fins, so that the stirring and mixing efficiency is higher.

[0011] The utility model is also provided with lower stirring fins. The upper stirring fins and the lower stirring fins respectively form stirring forces in the upper and lower directions during the stirring process, so as to make the urea produce a tumbling effect and improve the mixing efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0018] The drawings are specific embodiments of the present utility model.

[0019] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described in detail below in conjunction with the drawings and specific embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0020] Many specific details are set forth in the following description in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the protection scope of the present utility model is not limited by the specific embodiments disclosed below.

[0021] Such as Figures 1 to 4As shown in the figure, the stirring device for raw materials of sulfonate copolymer cement grinding aids includes a tank body 1. A stirring motor 2 is installed at the upper end of the tank body 1. The output end of the stirring motor 2 faces downward, and a rotating shaft 3 is fixedly connected to its output end. The rotating shaft 3 rotates following the output end. After the rotating shaft 3 extends into the tank body 1, a stirring shaft 4 is key-connected. A number of upper stirring fins 5 are installed on the stirring shaft 4, and the stirring shaft 4 can move up and down on the rotating shaft 3.

[0022] A cylinder 6 (which can also be an oil cylinder) is installed at the lower end of the tank body 1. The output end of the cylinder 6 faces upward, and a fixed shaft 7 is installed at its output end. The fixed shaft 7 extends upward into the tank body 1, and there is a sealed sliding connection between the fixed shaft 7 and the tank body 1. There are two ways to connect the above output end and the fixed shaft 7:

[0023] Method 1: The fixed shaft 7 is fixedly connected to the output end, and the fixed shaft 7 cannot rotate. After the fixed shaft 7 extends into the tank body 1, a filter screen 8 is installed on the fixed shaft 7. The periphery of the filter screen 8 is slidably connected to the inner wall of the tank body 1, and the filter screen 8 can move up and down along the inner wall of the tank body 1; the upper end of the fixed shaft 7 contacts the lower end of the stirring shaft 4, and it is preferably connected by a ball joint.

[0024] Method 2: The fixed shaft 7 is rotatably connected to the output end. That is to say, on the one hand, the fixed shaft 7 can move up and down with the output end, and on the other hand, it can rotate around the output end under the action of an external force. The upper end of the fixed shaft 7 is fixedly connected to the stirring shaft 4 and rotates synchronously under the drive of the stirring shaft 4; an annular groove 9 is opened on the fixed shaft 7, and a sleeve 10 is sleeved on the annular groove 9. The filter screen 8 is fixed on the sleeve 10. When the fixed shaft 7 rotates, the filter screen 8 does not rotate or rotates slightly with the water flow; lower stirring fins 11 are installed on the fixed shaft 7.

[0025] The working process is as follows:

[0026] The first method: Urea and water are added into the tank body 1. The urea accumulates on the filter screen 8. The stirring motor 2 and the cylinder 6 are started. The stirring shaft 4 rotates with the motor. The upper stirring fins 5 stir the urea and water. At the same time, the output end of the cylinder 6 extends, driving the fixed shaft 7 to move upward, thereby driving the stirring shaft 4 and the filter screen 8 to rise simultaneously. The filter screen 8 also drives the urea to rise. Then the output end of the cylinder 6 retracts, and the filter screen 8 and the stirring shaft 4 descend. The urea leaves the filter screen 8 due to inertia and forms a floating state. At this time, the stirring shaft 4 is still rotating, and the floating urea and water are stirred during the rotation process. This is repeated, thereby improving the stirring efficiency.

[0027] The second method: Add urea and water into the tank body 1. The urea accumulates on the filter screen 8. Start the stirring motor 2 and the cylinder 6. The stirring shaft 4 rotates along with the motor. The upper stirring fins 5 stir the urea and water. The lower stirring fins 11 drive the water below the filter screen 8 to form a vortex, which impacts the urea above the filter screen 8, causing the urea to roll. At the same time, the output end of the cylinder 6 extends, driving the fixed shaft 7 to move upward, thereby driving the stirring shaft 4 and the filter screen 8 to rise simultaneously. The filter screen 8 also drives the urea to rise. Then the output end of the cylinder 6 retracts, and the filter screen 8 and the stirring shaft 4 descend. The urea leaves the filter screen 8 due to inertia and forms a floating state. At this time, the stirring shaft 4 is still rotating, and during the rotation, the floating urea and water are stirred, alternating up and down to form a rolling state, thereby improving the stirring efficiency.
