Currently, there is no effective way to deal with the dust pollution generated during air mill production, which creates difficulties for 6S management in production practice. Summary of the Invention
[0005] To address the shortcomings of existing technologies and the problem that current air mills cannot effectively handle grinding dust, this application provides an air mill dust collection device utilizing Bernoulli's principle. This device connects a diverter to the rear of the dust collection pipe, introducing compressed air through the diverter to create a pressure difference within the dust collection pipe, thus solving the technical problem of grinding dust in air mills.

[0011] Positive effects:

This achieves the technical effect of collecting and centrally storing grinding dust.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Although embodiments of the present utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.
[0024] As shown in the figure, a dust collection device for an air mill utilizing Bernoulli's principle includes a dust collection shell 1, an air mill mounting port 2, a dust collection pipe port 3, a dust collection pipe 4, a high-pressure air inlet pipe 5, a diverter 6, and a dust discharge pipe 10.
[0025] The dust collection housing 1 is a cover adapted to the air mill, used to cover the air mill and prevent dust from overflowing; an air mill mounting port 2 is provided in the middle of the dust collection housing 1 for assembling the dust collection housing 1 onto the air mill; a dust collection pipe port 3 is provided on the dust collection housing 1, and a dust collection pipe 4 is installed on the dust collection pipe port 3, so that the dust collection housing 1 is connected to the front of the dust collection pipe 4; a diverter 6 is connected to the rear of the dust collection pipe 4, and a high-pressure air inlet pipe 5 is connected to the diverter 6. Compressed air is introduced through the diverter 6, forming an air pressure difference in the dust collection pipe 4, and the dust generated by the air mill is discharged to the dust collection container through the dust discharge pipe 10.
[0026] To ensure the stability of the structure in this embodiment, the drainer 6 is an air amplifier with a slit flow channel, including a drainer dust inlet 7, a drainer high-pressure air inlet 8, and a drainer dust outlet 9. The drainer dust inlet 7 is connected to the dust collection pipe 4, the drainer high-pressure air inlet 8 is connected to the high-pressure air inlet pipe 5, and the drainer dust outlet 9 is connected to a dust discharge pipe 10 for discharging dust. Compressed air is introduced through the drainer 6 to form an air pressure difference in the dust collection pipe 4, thereby discharging the dust generated by the air mill into the dust collection container for storage.
[0027] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages:
[0028] Because a compressed air inlet 6 is installed on the dust collection pipe 4, compressed air is introduced through the high-pressure air inlet 8 of the inlet 6. Therefore, the dust generated when the air mill is working is drawn into the high-velocity, low-pressure zone of the inlet 7 of the inlet 6 through the dust collection pipe 4 connected to the dust collection pipe 3 on the dust collection shell 1. After entering the high-velocity, low-pressure zone, it is carried into the dust collection container behind by the high-speed air through the dust outlet 9 of the inlet 6.
[0029] Because the high-pressure air inlet pipe 5 is connected to the high-pressure air inlet port 8 of the duct when the air mill is working, compressed air is input into the duct. Therefore, the dust generated during the grinding process can be collected quickly and easily during the operation of the air mill, reducing the harm to the environment and construction personnel.
[0030] The working process of this embodiment:
[0031] When the air mill is working, the dust generated is concentrated in the dust collection shell 1. When compressed air is injected into the high-pressure air inlet 8 of the diverter 6 through the high-pressure air inlet pipe 5, a high-velocity, low-pressure zone is formed inside the diverter 6, with relatively low air pressure. At the dust suction port 7 of the diverter, a low-velocity, high-pressure zone is formed, with relatively high air pressure. The airflow velocity at the dust collection pipe port 3 is slow, forming a pressure difference, which in turn draws the dust in the dust collection shell 1 into the dust collection pipe 4. When the dust reaches the diverter 6, it is carried by the high-pressure airflow and discharged from the dust outlet 9 of the diverter into the dust collection container, thereby achieving the purpose of collecting dust and reducing pollution.
[0032] The working principle of this embodiment:
[0033] The function of the inlet 6 is based on the wall adhesion effect in fluid mechanics. When compressed air flows out from a gap, it forms a high-speed flow along the nearby surface. Then, according to Bernoulli's principle, the high-pressure flow of gas creates a low-pressure zone around it, i.e., a high-velocity, low-pressure zone. This high-velocity, low-pressure zone attracts surrounding air to join the flow, thereby increasing the total airflow. In other words, the dust generated by the air mill is drawn into the high-velocity, low-pressure zone of the inlet 6 through the interface on the dust collection device connected to the dust collection pipe. After entering the high-velocity, low-pressure zone, it is carried by the high-speed air into the dust collection container behind it.
[0034] It is worth noting that all contents not described in detail in the specification are existing technologies known to those skilled in the art, and the model parameters of the drainer 6 are not specifically limited and can be determined using conventional equipment. Electrical control components not mentioned in this technical solution are not shown in the figure because they are existing technologies, and will not be described here.
[0035] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
