DETAILED DESCRIPTION

[0024] The present invention is further described below in conjunction with the accompanying drawings and embodiments. The present invention includes but is not limited to the following embodiments.

[0025] First embodiment:

[0026] like Figure 1-4As shown, the air intake device for the Raymond mill provided by the utility model includes: a grinding device 100 and an air intake pipe 200, the grinding device 100 and the air intake pipe 200 are connected, the air intake pipe 200 includes a ventilation cavity 201 and a cover plate 202, an annular groove 203 is provided in the ventilation cavity 201, and the center of the annular groove 203 is opened, and an adjustment component 300 is also installed in the air intake pipe 200, and the adjustment component 300 includes a turntable 304 installed in the annular groove 203 provided in the ventilation cavity 201, an adjustment plate 306 is welded to the upper end of the turntable 304, and partitions 308 are symmetrically arranged at both ends of the adjustment plate 306, and a motor spindle 302 is also installed at the lower end of the turntable 304, and the output end of the motor spindle 302 is connected to the turntable 304, and the adjustment component 300 also includes a fixed frame 301, and the fixed frame 301 is welded to the lower end of the air intake pipe 200, and the motor spindle 30 2 is engaged and fixed in the fixed frame 301. The staff will adjust the size of the air inlet opening of the Raymond mill according to different materials and different grinding requirements to ensure that the most suitable airflow conditions are provided. The motor spindle 302 is connected through PLC programming control. In actual use, the partition 308 is horizontally placed in the ventilation cavity 201. The staff starts the motor spindle 302, and the rotation of the motor spindle 302 drives the turntable 304 in the annular groove 203 to rotate. Through the rotation of the turntable 304, the adjustment plate 306 welded on the turntable 304 rotates synchronously with the partition 308. Through the rotation of the partition 308, the partition 308 and the side wall of the ventilation cavity 201 are staggered at an angle. When the partition 308 and the side wall of the ventilation cavity 201 are staggered at a certain angle, the air flow path or flow rate inside the ventilation cavity 201 will be changed, thereby adjusting the dynamics of the intake air flow.

[0027] By using multiple parts in the adjustment component 300 in coordination, the adjustment component 300 driven by the motor spindle 302 can accurately control the angle of the partition 308 according to actual production needs, thereby accurately adjusting the gas flow rate, so that the Raymond mill can provide the most suitable airflow conditions under different materials and different grinding requirements, thereby improving the grinding fineness and quality.

[0028] Second embodiment:

[0029] like Figure 2-4 As shown, an adjusting tooth 303 is sleeved on the output end of the motor main shaft 302 , and the adjusting tooth 303 provided on the output end of the motor main shaft 302 is engaged with a limiting groove 305 provided on the lower end of the rotating disk 304 .

[0030] The adjusting tooth 303 provided at the output end of the motor spindle 302 is engaged with the limiting slot 305 provided at the lower end of the turntable 304. In actual use, it is only necessary to engage the limiting slot 305 provided at the bottom of the turntable 304 with the adjusting tooth 303 provided at the output end of the motor spindle 302. Compared with the traditional fixed connection method through the connecting sleeve, the engaging connection method simplifies the installation process. It is only necessary to engage the limiting slot 305 with the adjusting tooth 303, thereby avoiding the complicated installation steps and tool requirements in the traditional connection method. At the same time, when it is necessary to disassemble or replace parts, it can also be completed quickly, thereby improving the maintainability of the device.

[0031] Third embodiment:

[0032] like Figure 4 As shown, two ends of the adjustment plate 306 are provided with clamping cavities 307 , and the partition plate 308 is mounted by clamping through the clamping cavities 307 .

[0033] By using the adjustment plate 306, the card cavity 307 and the partition 308 in coordination, in actual use, the operator only needs to easily snap the partition 308 into the card cavity 307 on the end side of the adjustment plate 306, without the need for complicated tools or steps, thus saving time and labor. When the partition 308 has been used for a long time, the partition 308 can be quickly replaced and installed by snapping.

[0034] Fourth embodiment:

[0035] like Figure 3-4 As shown, the adjustment plate 306 is arranged symmetrically in the horizontal and vertical directions, and the four end surfaces of the adjustment plate 306 are all provided with a clamping cavity 307 . The four end surfaces of the adjustment plate 306 can form four interface areas by clamping four partitions 308 .

[0036] Four interface areas can be formed by engaging four partitions 308 on the four end surfaces of the adjusting plate 306. In actual use, when the motor shaft 302 drives the turntable 304 to rotate, the airflow is guided and distributed more evenly through the four formed interface areas. At the same time, the motor shaft 302 is used to accurately control the rotation speed of the turntable 304 and the adjusting plate 306, and the airflow enters the grinding mill equipment, which can increase the material throughput rate, reduce blockage and backflow, and significantly improve production efficiency.

[0037] Fifth embodiment:

[0038] like Figure 5 As shown, a filter plate 400 is also provided in the ventilation cavity 201 , one end of the filter plate 400 protrudes from the outer wall of the ventilation cavity 201 , a sealing sheet is provided at the protruding port of the filter plate 400 , and the filter plate 400 can be installed at the inner end of the ventilation cavity 201 in a pull-out manner.

[0039] By arranging the filter plate 400 in the ventilation cavity 201, the filter plate 400 can effectively intercept dust and other tiny particles in the intake air and prevent them from entering the main unit of the Raymond mill, thereby avoiding contamination of the raw materials and ensuring the purity and quality of the final product.

[0040] Sixth embodiment:

[0041] like Figure 1 , Figure 5 As shown, the air intake duct 200 further includes a positioning cavity 204 , a positioning hole is provided at the upper end of the positioning cavity 204 , and a rubber gasket 205 is also installed on the inner circle of the positioning cavity 204 .

[0042] By setting the positioning cavity 204, in actual use, it is only necessary to engage the air intake pipe 200 on the air intake port of the Raymond mill, and then quickly install the air intake pipe 200 on the air intake port of the Raymond mill through two positioning bolts. At the same time, the rubber gasket 205 provided in the positioning cavity 204 can achieve the tightness of the connection between the two.

[0043] Working principle: During actual use, the partition 308 is placed horizontally in the ventilation cavity 201. The staff starts the motor spindle 302, and the rotation of the motor spindle 302 drives the turntable 304 in the annular groove 203 to rotate. Through the rotation of the turntable 304, the adjustment plate 306 welded on the turntable 304 rotates synchronously with the partition 308. Through the rotation of the partition 308, the partition 308 and the side wall of the ventilation cavity 201 are staggered at an angle. When the partition 308 and the side wall of the ventilation cavity 201 are staggered at a certain angle, the air flow path or flow rate inside the ventilation cavity 201 will be changed, thereby adjusting the dynamics of the intake air flow.

[0044] The above embodiment is only one of the preferred implementation modes of the present utility model and should not be used to limit the protection scope of the present utility model. Any changes or modifications that are made to the main design concept and spirit of the present utility model without any substantive significance, as long as the technical problems solved are still consistent with the present utility model, should be included in the protection scope of the present utility model.
