Description

Technical Field

[0001] The utility model belongs to the technical field of air intake devices, and particularly relates to an air intake device for a flour mill. Background Art

[0002] The air intake device of a flour mill is a key component in its air circuit system, mainly responsible for conveying necessary air flow into the mill to achieve drying of materials, cooling during grinding, and assisting in classification and conveying of powders. In the prior art, an air inlet is usually provided at the top of the device housing, an air outlet pipe is provided at the bottom, and a first filter screen and a second filter screen are provided inside the device housing to filter the gas entering the inside of the device housing. However, in this way, a cleaning component for cleaning the filter screen is not provided inside the housing device. As the working time increases, dust and fine powder will gradually accumulate on the filter screen. Without an automatic cleaning mechanism, the blockage of the filter screen will become more and more serious, resulting in a reduction in the air intake volume, affecting the ventilation efficiency of the flour mill, and further reducing the grinding efficiency and output.

[0003] For example, the utility model with the publication number CN220780610U discloses an air intake device for a Raymond mill for bentonite processing. In the technical solution of this patent, an air inlet is provided at the top of the device housing, an air outlet pipe is connected to the bottom of the device housing, a gas guiding channel is provided inside the device housing, and a first filter screen and a second filter screen are installed at the middle position of the device housing to filter the gas entering the inside of the device housing. However, in this way, a cleaning component for cleaning the filter screen is not provided inside the housing device. As time goes by, dust and impurities in the air will accumulate on the filter screen. Without an effective cleaning mechanism, the filter screen will gradually become blocked, which will reduce the air flow rate, lower the efficiency of the system, and affect the normal operation and production capacity of the flour mill. Summary of the Utility Model

[0004] In view of this, in order to overcome the deficiencies of the prior art, the utility model provides an air intake device for a flour mill, which can not only filter the gas entering the inside of the housing through the first filter plate and the second filter plate, but also clean the first filter plate through the cleaning component, effectively preventing the air flow from being blocked due to dust blockage, thereby ensuring smooth air intake of the flour mill and maintaining or improving the working efficiency of the equipment.

A cleaning component for cleaning the first filter plate 105 is provided at the left end of the first filter plate 105.

[0021] As Figure 1 、 3As shown in the figure, the cleaning component includes sliding grooves 201 provided on the front and rear side walls of the housing 101. Sliders 202 are slidably arranged inside the sliding grooves 201. A rotating rod 203 is rotatably arranged between the two sliders 202. Brush plates 204 for brushing the first filter plate 105 are evenly arranged on the rotating rod 203. A first driving member for driving the rotating rod 203 to move up and down is arranged at the upper end of the housing 101, and a second driving member for driving the rotating rod 203 to rotate is arranged on the side wall of the first groove 104.

[0022] As Figure 1 , 3 shown in the figure, the first driving member includes a moving frame 205 arranged at the upper ends of the two sliders 202. A telescopic push rod 206 is arranged at the upper end of the housing 101. The output end of the telescopic push rod 206 extends into the interior of the housing 101 and is connected to the moving frame 205. The second driving member includes a rack plate 207 arranged on the side wall of the front first groove 104. A gear 208 meshing with the rack plate 207 is arranged on the rotating rod 203. Starting the telescopic push rod 206 can move the moving frame 205 up and down. The moving frame 205 drives the slider 202 to move up and down. The slider 202 drives the rotating rod 203 to move up and down. Further, the gear 208 on the rotating rod 203 rotates under the action of the rack plate 207. The rotation of the gear 208 drives the brush plate 204 to rotate, thereby cleaning the first filter plate 105.
