Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 1-2 This utility model provides a device for preventing ring formation in the front section of a rotary kiln, comprising: a fixed base plate 1.

[0026] Specifically, it includes a fixed base plate 1, a fixed plate 2 connected to the upper end of the fixed base plate 1, a hopper 3 connected to the fixed plate 2, a feed pipe 4 connected to the hopper 3, a Raymond mill 5 connected to the feed pipe 4, a first connecting pipe 6 connected to the Raymond mill 5, a cyclone dust collector 7 connected to the first connecting pipe 6, a second connecting pipe 8 connected to the cyclone dust collector 7, a ash storage tank 9 connected to the second connecting pipe 8, a third connecting pipe 10 connected to the third connecting pipe 10, a Roots blower 11 connected to the third connecting pipe 11, a fourth connecting pipe 12 connected to the fourth connecting pipe 12 via a flange 13, a connecting hose 14 connected to the connecting hose 14, a spray pipe 15 connected to the fourth connecting pipe 13, and a movable bracket 16 provided at the upper end of the fixed base plate 1.

[0027] In this embodiment, the Raymond mill 5 utilizes the centrifugal force of the grinding rollers to tightly press the grinding ring, achieving the effect of pulverization. The material is pulverized under strong rolling pressure.

[0028] It should be noted that the cyclone dust collection device 7 effectively removes dust from the airflow, reducing the dust emission concentration.

[0029] Specifically, the hopper 3 is located at the end of the fixed plate 2 away from the fixed base plate 1, and the feed pipe 4 is fixedly connected to the lower end of the hopper 3. The end of the feed pipe 4 away from the hopper 3 is fixedly connected to the upper end of the Raymond mill 5, and the first connecting pipe 6 is fixedly connected to the lower end of the Raymond mill 5. The Raymond mill 5 is fixedly connected to the upper end of the fixed base plate 1. The end of the first connecting pipe 6 away from the Raymond mill 5 is fixedly connected to the cyclone dust collector 7. The end of the second connecting pipe 8 away from the ash storage tank 9 is fixedly connected to the cyclone dust collector 7. The cyclone dust collector 7 is fixedly connected to the upper end of the fixed base plate 1. The ash storage tank 9 is fixedly connected to the upper end of the fixed base plate 1. The end of the third connecting pipe 10 away from the Roots blower 11 is fixedly connected to the lower end of the ash storage tank 9. The Roots blower 11 is fixedly connected to the upper end of the fixed base plate 1. The spray pipe 15 is fixedly connected to the upper end of the movable support 16. The movable support 16 moves on the upper end of the fixed base plate 1 by means of wheels provided at the lower end.

[0030] As a preferred embodiment, the provided ash storage tank 9 is used to store the dust separated from the dust-laden gas, which can avoid secondary pollution of the dust and facilitate subsequent processing and utilization.

[0031] In a preferred embodiment, a Roots blower 11 is provided to provide a stable airflow for conveying or processing dust or other materials in the dust storage tank.

[0032] As a preferred implementation method, the specific operating procedures (such as injection frequency and injection pressure) for preventing ring formation in rotary kilns need to be set according to the actual operating conditions of the rotary kiln and the characteristics of the materials.

[0033] In operation, the material is first fed into the hopper 3 and then into the Raymond mill 5 through the feed pipe 4 for crushing. The crushed material is then carried by the airflow through the first connecting pipe 6 into the cyclone dust collector 7. In the cyclone dust collector 7, the dust-laden airflow generates centrifugal force during rotation, causing dust particles to be thrown against the cylinder wall and fall into the ash storage tank 9. The purified gas is discharged from the other end of the cyclone dust collector 7. The dust in the ash storage tank 9 enters the Roots blower 11 through the third connecting pipe 10. The Roots blower 11 provides a stable airflow, which transports the dust through the fourth connecting pipe 12, flange 13, and connecting hose 14 to the nozzle 15. The nozzle 15 can spray the dust to a designated location as needed. By setting up the movable support 16 and the nozzle 15, the position of the nozzle 15 can be flexibly adjusted to perform regular cleaning or blowing operations on the front section of the rotary kiln, effectively preventing material adhesion and ring formation.

[0034] The device for preventing ring formation in the front section of a rotary kiln, as described in this invention, can not only effectively prevent ring formation in the front section of the rotary kiln, but also achieve efficient collection, storage, transportation and treatment of dust.

[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
