Description

Technical Field

[0001] The utility model relates to the technical field of grinding mills, in particular to a grinding mill inner wall cleaning structure. Background Art

[0002] A pulverizer is a mechanical device used to grind solid materials into powder. It is widely used in the chemical, pharmaceutical, food, building materials, metallurgy, ceramics and other industries. There are many types of pulverizers. Based on their working principles and structural characteristics, they can be mainly divided into ball mills, roller mills, and vibrating mills.

[0003] The inner wall cleaning structure is a device used to ensure that the materials adhering to the inner wall of the grinding mill can be effectively removed during operation, so as to maintain the cleanliness of the equipment and production efficiency.

[0004] However, the current inner wall cleaning structure only simply cleans the inner wall of the grinding mill and cannot achieve a good cleaning effect. Taking the vertical mill as an example, the grinding method of the vertical mill is to put the material onto the grinding disc, and rely on the rotation of the grinding disc to make the grinding disc roll through the grinding parts to achieve the grinding effect. However, after being ground by the grinding parts, the crushed material is very easy to form agglomerates composed of powder. These agglomerates wrap the material that has not been ground and adhere to the grinding disc, resulting in a decrease in grinding efficiency and also causing the next grinding material to be contaminated. The material ground into powder is blown from the bottom and rises to the recovery device at the top, and the recovery device is also easily blocked by the powder material, which increases the risk of damage to the recovery device.

[0033] Example 2

[0034] Reference Figure 4 、 Figure 5 and Figure 6 , which is the second embodiment of the present utility model, is based on the previous embodiment. The vibration component 11 includes a vibrator 1105 and a mounting base 1103. The bottom of the vibrator 1105 is fixedly connected to the top of the mounting base 1103. Two clamping arms 1101 for fixing are also provided on both sides of the mounting base 1103. The bottom of the clamping arm 1101 is fixedly connected to the top of the outer wall 1.

[0035] Specifically, a buffer plate 8 is also provided at the bottom of the vibration component 11, and a connecting base 9 is provided at the bottom of the buffer plate 8. The top of the buffer plate 8 is fixedly connected to the top of the mounting base 1103. A connecting base 9 is also provided at the bottom of the buffer plate 8. The side of the connecting base 9 is fixedly connected to the bottom of the clamping arm 1101. A connecting plate 10 is provided at the bottom of the connecting base 9. The bottom of the connecting plate 10 is fixedly connected to the top of the outer wall 1. A connecting block 1102 is provided at the bottom of the clamping arm 1101. Knobs 1104 for adjusting the angle are provided on both sides of the connecting block 1102. The bottom of the connecting block 1102 is fixedly connected to the adjacent surface of the connecting base 9. A gasket 1106 for pressing the mounting base 1103 is provided at one end of the clamping arm 1101.

[0037] Working principle: In actual use, after the material is put into the grinding mill, the material falls onto the grinding disc 7, and then the rotation of the grinding disc 7 causes the material on the grinding disc 7 to be ground by the grinding component 6. The ground powder is blown up to the top recovery device for recovery by the second fan 5. At the same time, the wind force output by the first fan 206 is compressed by the valve 205 and the compression chamber 204, and then blows up the lumps deposited on the grinding disc 7 through the main nozzle 201 and the auxiliary nozzle 202, thereby cleaning the grinding disc 7, so that the ground powder is blown up for recovery, and the material that has not been ground yet will fall back onto the grinding disc 7 for re-grinding due to gravity. At the same time, the vibration device on the top vibrates the recovery device, and the vibration is transmitted to the recovery device through the buffer plate 8 through the vibrator 1105, so that the material blocked on the recovery device falls off for recovery, which ultimately cleans the inner wall and increases production, and reduces the risk of damage to the recovery device due to blockage.
