Technical Field

[0001] This utility model relates to the field of air mill technology, and in particular to an air mill with a dust extraction function. Background Technology

[0002] Pneumatic sanders are generally used for metal grinding, cutting, paint removal, and putty sanding. There are disc sanders, track sanders, and belt sanders. Disc sanders come in two types: combination sanders and single-motion disc sanders, suitable for rough sanding. Track sanders are suitable for finishing. Belt sanders can be used when sanding narrow areas.

[0003] When an air mill is in operation, it produces fumes, sparks, and particulate matter upon contact with the surface of an object. These substances are carried away by the mill's discs and can release into the environment, causing health problems for workers. Utility Model Content

Detailed Implementation

[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 of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0024] Example 1:

[0025] Reference Figure 1-2 A dust-collecting air mill includes an air mill body 1, a dust-collecting structure 2 is installed at the output end of the air mill body 1, and a diversion pipe 3 is connected to both ends of the dust-collecting structure 2, and a separation component 5 is connected to the other end of the diversion pipe 3.

[0026] The dust collection structure 2 includes an arc-shaped plate 7, a mounting hole groove 6 opened at the center of the arc-shaped plate 7, arc-shaped grooves 8 opened on the inner outer walls of both ends of the arc-shaped plate 7, an arc-shaped strip 9 installed on the inner wall of one end of the arc-shaped groove 8, and inlets 10 opened at equal intervals on the outer walls of the arc-shaped strip 9 and the outer walls of the arc-shaped plate 7.

[0027] Both ends of the outer wall of one side of the arc plate 7 are provided with connection ports 11, and one end of the diversion pipe 3 is connected to the connection port 11 respectively; the cross section of the arc plate 7 is an elliptical structure, and there is a gap between the arc strip 9 and one end of the air mill body 1. The arc strip 9 at the arc groove 8 cooperates with the inlet 10 on the arc plate 7 to intercept larger impurities, making it easy to suck in, easy to handle smoke and dust, and easy to use.

[0028] The other end of the diversion tube 3 is connected to the top of the outer wall of one side of the collection tube 12, and a fixing sleeve 4 is fitted on the outer wall of one end of the diversion tube 3. The fixing sleeve 4 fixes one end of the diversion tube 3 together, which facilitates cable management.

[0029] Example 2:

[0030] Reference Figure 1 and Figure 3-4 The separation assembly 5 includes a collection cylinder 12, a mounting cover 13 installed on the top outer wall of the collection cylinder 12, an exhaust port 14 opened at the center of the mounting cover 13, and a fan 16 installed on the top outer wall of the mounting cover 13.

[0031] The input end of the blower 16 is connected to one end of the exhaust port 14 of the mounting cover 13, and a protective shell 17 is installed on one side of the outer wall of the mounting cover 13 at the blower 16. The output end of the blower 16 extends out of the outer wall of the protective shell 17. When the airflow enters, it sucks the particles and dust generated by grinding into the collection cylinder 12. Then the gas is discharged by the blower 16. The particles in the air are intercepted at the cylindrical filter screen 15 and attached to the cylindrical filter screen 15, which facilitates the intake of the dust generated during the operation and reduces the impact on personnel.

[0032] A cylindrical filter 15 is installed on the inner wall of the mounting cover 13 at the exhaust port 14, and the cylindrical filter 15 has a cylindrical structure. Universal wheels are installed on the bottom outer wall of the collection cylinder 12 at equal intervals.

[0033] The inner wall of the cylindrical filter screen 15 is equipped with a vibrator 18, and the vibrator 18 is fixed to the inner wall of the cylindrical filter screen 15. After the vibrator 18 is started, it generates a vibration effect in the cylindrical filter screen 15, shaking off the particulate dust attached to the outer wall of the cylindrical filter screen 15 into the collection cylinder 12 for collection, reducing the clogging of the cylindrical filter screen 15, reducing the load on the fan 16, and facilitating use.

[0034] The vibrator 18, the air mill body 1, and the blower 16 are connected to a switch via wires, and the switch is connected to a power source via wires.

[0035] Working principle: During use, the grinding disc is removed from the air mill body 1, and the arc plate 7 is installed in the air mill body 1 through the mounting slot 6. The grinding disc is then installed back into the air mill body 1. When the air mill body 1 is in operation, there is a certain distance between the arc plate 7 and the object when the grinding disc comes into contact with it. After the blower 16 is started, gas is drawn from the collection cylinder 12 through the exhaust port 14. The gas enters through the arc groove 8 of the arc plate 7 via the diverter pipe 3. As the airflow enters, it simultaneously draws in the grinding particles and dust into the collection cylinder 12. Subsequently, the gas is discharged by the blower 16. Airborne particles are intercepted and adhered to the cylindrical filter screen 15, facilitating the intake of smoke generated during operation. Dust is reduced, minimizing the impact on personnel. The arc-shaped strip 9 at the arc-shaped groove 8, in conjunction with the inlet 10 on the arc-shaped plate 7, intercepts larger impurities, facilitating suction, dust handling, and ease of use. The vibrator 18 in the cylindrical filter 15 is activated periodically. After the vibrator 18 is activated, it generates vibration in the cylindrical filter 15, shaking off the particulate dust adhering to the outer wall of the cylindrical filter 15 into the collection cylinder 12 for collection, reducing the clogging of the cylindrical filter 15, reducing the load on the fan 16, and facilitating use. The fixing sleeve 4 fixes one end of the diversion pipe 3 together, facilitating cable management. The working part of the vibrator is a rod-shaped hollow cylinder with an eccentric oscillator inside. Driven by the motor, it rotates at high speed to generate high-frequency micro-amplitude vibration.
