[0002] A mixer is a construction machinery that is mainly used to mix cement, sand, various dry mortar and other construction materials. It is a machine that has a shaft with blades rotating in a cylinder or trough to mix and mix a variety of raw materials to make a mixture or a suitable consistency. There are many types of mixers, including forced mixers, single-shaft mixers, twin-shaft mixers, etc.

[0003] The mixer will generate dust when discharging materials. In the prior art, a high-pressure spray structure is generally installed directly at the mixer outlet to spray water mist toward the outlet to reduce dust. However, the water mist will fall on the surface of the discharged mixed material, thereby reducing the viscosity of the material. To this end, we provide a high-pressure spray dust reduction device for the drum mixer outlet to solve the above problem. Utility Model Content

[0028] An electric motor 12 is installed inside the end head 5, and an exhaust fan 6 is installed at the output end of the electric motor 12. When the electric motor 12 drives the exhaust fan 6 to rotate, the airflow is driven to flow upward, and the dust at the outlet of the mixer is sucked into the vertical cylinder 4 through the curved pipe 2. A vertical shaft 11 is arranged on the inner side of the vertical cylinder 4, and the upper end of the vertical shaft 11 is fixedly connected to the exhaust fan 6. A stirring plate 10 is fixedly connected to the outer surface of the vertical shaft 11. The stirring plate 10 is distributed in a conical spiral shape. The conical spiral stirring plate 10 is coaxially arranged with the vertical shaft 11. A plurality of vertical and axial holes are opened on the surface of the stirring plate 10 to facilitate the passage of airflow. When the exhaust fan 6 rotates, the stirring plate 10 is driven to rotate through the vertical shaft 11. The conical spiral stirring plate 10 can The water mist angles at different circumferential positions increase the contact time between the water mist and the dust in the airflow and improve the degree of absorption of the dust in the airflow. The vertical axis 11 is coaxially arranged with the vertical cylinder 4. The water outlet holes of the high-pressure spray cylinder 3 are evenly distributed in an array around the axis of the vertical axis 11. A plurality of circular rings 13 are fixedly inserted inside the vertical cylinder 4 and below the stirring plate 10. A sliding plate 14 is fixedly inserted inside the circular ring 13. There is a gap between the circular ring 13 and the vertical cylinder 4. The sliding plate 14 is high in the middle and low at both ends. The plurality of circular rings 13 are equidistantly distributed. Each sliding plate 14 has a different rotation angle relative to the vertical axis 11, so as to receive the mud falling from different positions. The mud falling on the sliding plate 14 tends to flow to both ends.

[0029] A sealing ring 7 is slidably sleeved on the lower end of the vertical cylinder 4. A plurality of through grooves 9 are provided on the outer surface of the vertical cylinder 4 and on the inner ring surface of the sealing ring 7.

[0030] Working principle: install the installation connecting ring 1 at the outlet of the mixer, start the motor 12 to drive the exhaust fan 6 to rotate, and at the same time supply water in the high-pressure spray barrel 3 to spray high-pressure water mist into the vertical barrel 4. The rotation of the exhaust fan 6 drives the airflow to flow upward, so that the curved pipe 2 draws the dust in the installation connecting ring 1 into the vertical barrel 4. When the exhaust fan 6 rotates, it drives the stirring plate 10 to rotate through the vertical shaft 11.

The mud mixed with the dust and the water mist falls downward, and multiple sliding plates 14 with different rotation angles can receive the mud dropped from different parts. Since the sliding plate 14 is high in the middle and low at both ends, the mud falling on the sliding plate 14 will flow to the side wall of the vertical barrel 4.
