Description

Technical Field

[0001] This utility model relates to the field of grinding mill technology, and more specifically to a spiral impeller for use in a grinding mill. Background Technology

[0002] Grinding mills are mainly used in the chemical industry for grinding materials such as glass, rubber, pesticides, enamel, paint, phosphate fertilizer, and paper. They are suitable for non-flammable and non-explosive materials with a Mohs hardness below 7 and a moisture content below 6%, such as talc, barite, calcite, limestone, manganese ore, iron ore, chromium ore, quartz, gypsum, and bentonite.

[0003] Existing grinding mills generally use blowers and classifiers. The blower provides circulating airflow for the entire grinding system, and the classifier separates coarse and fine powders. During the operation of the grinding mill, the upward airflow generated by the blower drives the grinding process, and then the powder is separated by the classifier installed on the upper side. The processing efficiency of the grinding mill depends on the airflow driven by the blower, resulting in low processing efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a spiral impeller for a grinding mill. As the main shaft rotates, it generates lateral wind that works in conjunction with the spiral wind generated by the fan. This results in high wind speed, strong powder carrying capacity, improved air conveying efficiency, and thus increased mill output.

[0005] Specifically, this utility model discloses a spiral impeller for a grinding mill, which is installed on the mill's frame and rotates with the mill's main shaft. It includes an upper impeller plate, a lower impeller plate, and blades. The blades are fixedly installed between the upper impeller plate and the lower impeller plate. An installation assembly is provided at the bottom of the lower impeller plate, and the installation assembly is connected to the frame.

[0006] The advantage of this invention is that by setting a spiral impeller that rotates with the main shaft of the grinding mill, the lateral wind is generated in combination with the spiral wind generated by the fan. The wind speed is high, the powder carrying capacity is strong, the air conveying efficiency is improved, and thus the output of the grinding mill is increased, and the processing efficiency of the grinding mill is improved.

[0007] Furthermore, the mounting assembly includes a mounting shaft and a mounting plate, wherein the mounting shaft is vertically arranged and its two ends are connected to the lower plate of the wind turbine and the mounting plate.

[0008] The advantages of adopting the above technical solution are that the mounting plate serves as a connection, the vertically set mounting shaft serves as a support, keeping the blades at the required height, and the mounting plate ensures that the entire spiral impeller will not shake during use, thus ensuring stable airflow.

[0009] Furthermore, the upper plate of the wind turbine is provided with ventilation holes.

[0010] The advantages of adopting the above technical solution are that the ventilation holes are used for air intake. After the air is intake, it is blown to the side by the blades, causing the coarse powder particles to move towards the inner wall of the mill. The coarse powder particles fall off along the inner wall. At the same time, the exhaust air is combined with the air from the fan to form a cyclone, which improves the powder carrying capacity and improves the efficiency of the mill.

[0011] Furthermore, both the upper and lower plates of the wind turbine are circular plates.

[0012] Furthermore, the blades are vertically installed between the upper plate and the lower plate of the wind turbine, with the blade tips extending from the side of the upper plate.

[0013] Furthermore, the mounting plate is provided with mounting holes.

[0014] The advantage of adopting the above technical solution is that the mounting holes are designed to fix the mounting plate, and the mounting plate can be disassembled and installed.

[0015] Furthermore, the number of blades is multiple and evenly arranged along the circumference of the upper plate of the wind turbine.

[0016] The advantage of adopting the above technical solution is that the uniformly arranged blades generate a uniform airflow during rotation, avoiding excessively high or low local wind speeds, ensuring the stability and consistency of the overall airflow, thereby improving the pushing and separation effect on powder.

[0024] The present invention will now be described in further detail with reference to the accompanying drawings.

[0025] like Figure 1-4 As shown, this utility model discloses a spiral impeller for a grinding mill, which is installed on a spiral frame 1 of the grinding mill. The spiral frame 1 is connected to the main shaft 2 of the grinding mill. As the main shaft 2 of the grinding mill rotates, it includes: an upper plate 3, a lower plate 4, and blades 5. The blades 5 are fixedly installed between the upper plate 3 and the lower plate 4. An installation assembly is provided at the bottom of the lower plate 4, and the installation assembly is connected to the spiral frame 1.

[0026] The advantage of this invention is that by setting a spiral impeller that rotates with the main shaft 2 of the grinding mill, the lateral wind is generated in combination with the spiral wind generated by the fan. The wind speed is high, the powder carrying capacity is strong, the air conveying efficiency is improved, and thus the output of the grinding mill is increased, and the processing efficiency of the grinding mill is improved.

[0027] In some implementations, the mounting assembly includes a mounting shaft 6 and a mounting plate 7. The mounting shaft 6 is vertically positioned and connected at both ends to the impeller lower plate 4 and the mounting plate 7. The two ends of the mounting shaft 6 can be fixed to the impeller lower plate 4 and the mounting plate 7 by welding or screws. The length of the mounting shaft 6 can be changed according to different models of grinding mills to ensure that the position of the blades 5 is at the required height and better matches the fan.

[0028] Furthermore, the upper plate 3 and lower plate 4 of the impeller are provided with ventilation holes. Airflow passes through the ventilation holes on the upper plate 3 and is then blown out to the side by the impeller blades 5. Since both the upper plate 3 and lower plate 4 are circular plates, the through holes in the middle are used for air intake, accelerating the falling of coarse particles. Then, during rotation, the coarse particles are thrown against the inner wall of the mill, causing them to fall quickly to the grinding roller assembly at the bottom for grinding. At the same time, the airflow combines with the spiral wind of the fan blowing upward from the bottom, improving the powder carrying capacity and increasing the efficiency of the mill. Furthermore, the blades 5 are vertically installed between the upper plate 3 and lower plate 4 of the impeller. The ends of the blades 5 extend from the side of the upper plate 3 of the impeller, and the two sides of the blades 5 are fixedly connected to the upper plate 3 and lower plate 4 of the impeller. The design of the ends of the blades 5 extending from the side of the upper plate 3 of the impeller allows the blades 5 to have more full contact with the external air during rotation, enhancing the airflow disturbance effect.

[0029] Meanwhile, the mounting plate 7 is provided with mounting holes, and the plum blossom frame 1 is also provided with mounting holes, which can be connected by screws to make the entire spiral impeller detachable.

[0030] Furthermore, the number of blades 5 is evenly arranged along the circumference of the upper plate 3 of the impeller. One end of the blade 5 faces the inner side of the upper plate 3 of the impeller, and the other end faces the outer side. The blades 5 form an air guide channel between each other. During the rotation of the blades 5, a uniform airflow is generated, avoiding excessively high or low local wind speeds and ensuring the stability and consistency of the overall airflow, thereby improving the pushing and separation effect on the powder.

[0031] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
