Specifically, a cleaning gas, such as nitrogen, can be injected into the air storage tank 31 to avoid the influence of the gas on the use of this application.

[0025] In an optional embodiment: The air jet part includes an air jet pipe 242 and a hose 241. One end of the hose 241 is communicated with the air jet pipe 242, and the other end of the hose 241 is communicated with the main air jet pipe 21.

[0026] In an optional embodiment: Electric louver structures are installed on both sides of the main air jet pipe 21. The electric louver structure adopts an automatic louver with an automatically adjustable louver angle in the prior art, such as a louver with model LS-001. The electric louver structure includes a frame body 22 and a plurality of fan blades 23. One end of the air jet pipe 242 is installed on the fan blade 23. The angle of the fan blade 23 can be adjusted by the motor in the electric louver, so that the jet directions of the plurality of air jet pipes 242 installed on the fan blade 23 can change with the position of the fan blade 23, improving the jet range of the air jet part, making the jet range large, and improving the cleaning effect.

[0027] In an alternative embodiment: It further includes a moving component for driving the jetting part 2 to move in the direction of the vertical axis of the grinding cylinder 1. The moving component includes a hydraulic cylinder 5 installed at the bottom of the mounting fixing plate 3, and the output rod of the hydraulic cylinder 5 is connected to the main jet pipe 21.

Specifically, when the jetting part 2 is self-cleaned, only the valve needs to be opened, and only the multiple jet pipes 242 on one side of the main jet pipe 21 are allowed to pass air, while the multiple jet pipes 242 on the other side are blocked from passing air. By starting the pump body 33, the jet pipes 242 passing air can be aligned to jet air at the jet pipes 242 blocking air, enabling the multiple jetting members on one side to effectively clean the jetting members on the other side, and then following the above steps to effectively clean the jetting part 2 itself.

[0029] In an alternative embodiment: The grinding part includes two grinding shafts 6, and there are multiple grinding blocks 61 on the grinding shafts 6. The two grinding shafts 6 are arranged parallel to each other and rotatably connected inside the grinding cylinder 1. A driving part is also installed on the grinding cylinder 1 for driving the two grinding shafts 6 to rotate. Specifically, the two grinding shafts 6 rotate in opposite directions so that the multiple grinding blocks 61 can crush and grind the fed material. The driving part includes a driving motor installed outside the grinding cylinder 1. Gears are installed at the same end of the two grinding shafts 6, and the driving motor is connected to one of the grinding shafts 6, enabling the two gears to cooperate to cause relative rotation of the two grinding shafts 6.

[0032] Specifically, before feeding the light calcium carbonate, the grinding part is moved to the top side of the grinding cylinder 1 through the moving component. After the light calcium carbonate is ground, the controller operates the grinding part and the pump body 33 to work, pumping the gas in the air storage tank 31 into the air injection pipe 242, and spraying the gas from the air injection pipe 242 towards the grinding part. The grinding shaft 6 and the grinding blocks 61 in the grinding part rotate, so that the multiple air injection pipes 242 can spray gas on all sides of the grinding shaft 6 and the grinding blocks 61, and comprehensively clean the grinding shaft 6 and the grinding blocks 61, avoiding the contamination of the light calcium carbonate from the previous time on the grinding shaft 6 and the grinding blocks 61 and affecting the grinding effect of the light calcium carbonate next time.

[0033] During the cleaning process, the controller can be used to control the moving component to drive the air jet part 2 to move up and down repeatedly, and drive the electric louver structure to operate, so that the jet range of the multiple jet parts is wide, and the grinding shaft 6 and the grinding blocks 61 can be cleaned more effectively.

[0034] Certainly, when the calcium carbonate is ground and crushed in this application, the air jet part 2 can also be moved to the side of the grinding part through the moving component, and the air supply part is started to spray an appropriate air flow rate through the air injection pipe 242 to align with the grinding part to form an air flow layer. During the grinding process, under the blowing force of the air flow layer, it has a certain effect on preventing the material from adhering to the grinding shaft 6 and the grinding blocks 61.

[0035] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
