In addition, it should be understood that after reading the content of the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms also fall within the scope defined by the claims attached to the application.

[0019] Example 1: See Figures 1 to 2 This is the structural view of the utility model. Figure 1 A partial enlarged view of the center A shows a stirring device capable of removing dust, including a stirring chamber 8. Both ends of the stirring chamber 8 are connected to end plates 10, and the end plate 10 on the right is connected to the stirring chamber 8 through bolts and sealing gaskets. A main feed port and an auxiliary feed port are provided at the upper end of the stirring chamber 8. The main feed port is connected to a feeding device 6 through a plug valve 7. A sealing cover is provided at the auxiliary feed port. A stirring shaft is provided inside the stirring chamber 8 and the stirring shaft is rotatably provided with the end plate 10 through a bearing. The circumferential surface of the stirring shaft is provided with blades that are evenly distributed and cross-distributed on both sides of the axis. The end of the shaft passes through the end plate 10 and is connected to a power mechanism 11. The power mechanism 11 is arranged on a bottom bracket, and the bottom bracket is connected to the adjacent end plate 10. A discharge mechanism 12 is arranged at the bottom of the mixing bin 8. Materials are fed into the mixing bin 8 through the feeding device 6. If there is more than one type of material, auxiliary feeding can be carried out through the auxiliary feeding port. The power mechanism 11 is started to drive the mixing shaft and the mixing blades to rotate and stir. The plug valve 7 can effectively control the opening and closing of the feeding channel, and can also prevent dust from entering the feeding device 6 upward.

[0020] In order to be able to feed liquid materials into the stirring bin 8, a liquid feed connector 5 is provided on the inner side of the upper side wall of the stirring bin 8, a nozzle is provided at the lower end of the liquid feed connector 5, and the liquid feed connector 5 is connected to the liquid feeding device 6. Furthermore, in order to reduce dust inside the stirring bin 8, the liquid feed connector 5 can also be used to spray liquid to assist in dust reduction.

[0021] A connecting body 4 is provided on the inner side of the upper end side wall of the mixing bin 8, and the connecting body 4 is connected to a connecting pipe 3 by bolts. The end of the connecting pipe 3 is connected to a bag-type dust collector 1, and a negative pressure fan 2 is connected to the air outlet interface of the bag-type dust collector 1. When the negative pressure fan 2 is powered on, negative pressure is applied to the connecting pipe 3 through the bag-type dust collector 1, so that the negative pressure enters the connecting body 4 and the mixing bin 8 through the connecting pipe 3. The upper part of the connecting body 4 is a flange structure for docking the pipe. The lower end of the flange structure is connected to a cylinder 13, and the cylinder 13 is connected to the mixing bin 8 by welding. Four threaded holes are provided on the lower circumferential surface of the cylinder 13, and a sleeve 15 is provided on the outer side of the lower end of the cylinder 13. Four through holes corresponding to the positions of the threaded holes are provided on the circumferential surface of the upper part of the sleeve 15. The sleeve 15 and the cylinder 13 are connected by connecting bolts 14. In order to ensure that the gap at the joint will not leak air, thereby ensuring the transmission of negative pressure, a sleeve 15 and the cylinder 13 are connected. A sealing sleeve is arranged between the two sides. The lower end of the sleeve 15 is connected to a negative pressure bin 16. The bottom end surface of the negative pressure bin 16 is provided with evenly distributed negative pressure holes. The negative pressure generated by the negative pressure fan 2 passes through the connecting pipe 3, the connecting body 4, and the sleeve 15 and finally acts on the negative pressure holes of the negative pressure bin 16, so that the negative pressure bin 16 can extract dust in the mixing bin 8. In order to prevent the negative pressure bin 16 from excessively affecting the mixing of the dust material when extracting dust, a fixing bolt 18 is provided on the outside of the negative pressure bin 16.

The positive-pressure gas can assist the negative-pressure gas in extracting dust, thereby accelerating the efficiency of the floating dust moving toward the negative-pressure bin 16.

[0023] The utility model provides a dust removal device at the stirring device, and at the same time provides a structure for collecting dust on the inner side of the stirring device. The two cooperate to effectively remove dust without affecting the normal stirring of materials, thereby realizing the function of internal dust removal and reducing the impact on the environment.
