Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model. Example

[0021] refer to Figure 1-4 A dust removal device for putty powder processing shown in the figure includes a chassis 1, a dust collecting hood 5 and a negative pressure fan 8. The chassis 1 is a shell with a transparent front side. The front side of the chassis 1 is also provided with a box door 2. The left side of the box door 2 is hinged to the chassis 1 by a hinge. A door lock is provided between the right side of the box door 2 and the chassis 1. The box door 2 is also provided with an observation window 3 for observing the internal situation of the chassis 1. The observation window 3 is used for the staff to observe the internal situation of the chassis 1. The setting of the box door 2 is to facilitate the staff to clean and maintain the inner wall filter.

[0022] A discharge port is provided at the bottom of the chassis 1, and a solenoid valve 4 for controlling the opening and closing of the discharge port is provided at the discharge port. A dust hood 5 is connected to the right side of the chassis 1 through a bellows 6. The negative pressure fan 8 is also installed on the top of the chassis 1. Under the action of the negative pressure fan 8, negative pressure is formed at the dust hood 5.

[0023] like Figure 2As shown, the chassis 1 is also provided with a first filter 10 and a second filter 13 for filtering putty powder, and the second filter 13 and the first filter 10 are arranged in order from bottom to top in the chassis 1; the first filter 10 is installed inside the chassis 1 through the first mounting frame 9, and the second filter 13 is installed inside the chassis 1 through the second mounting frame 12. The second filter 13 is provided with two groups and is symmetrically arranged. The chassis 1 is also provided with a mounting frame 15, which is "V" shaped, and a through hole matching the size of the second mounting frame 12 is opened on the mounting frame 15. The second mounting frame 12 is hinged with the mounting frame 15, and a torsion spring is provided at the hinge. The second filter 13 is tiltedly installed in the chassis 1. The dust is driven by the wind force of the negative pressure fan 8, moves in the chassis 1, and is filtered and intercepted by the second filter 13. The tilted second filter 13 has a dust aggregation effect, which increases the working time of the second filter 13.

[0024] like Figure 3 As shown, the chassis 1 is also provided with an anti-blocking mechanism to prevent the second filter 13 from being blocked; the anti-blocking mechanism includes a pressure frame 11 and a push rod 7, the pressure frame 11 is slidably connected to the first mounting frame 9, the pressure frame 11 corresponds to the position of the second mounting frame 12, the push rod 7 is also provided on the outside of the chassis 1, the push rod 7 is connected to the pressure frame 11 through a connecting plate 14, under the push of the push rod 7, the pressure frame 11 moves in the vertical direction, the pressure frame 11 moves downward, and pushes the second mounting frame 12 to rotate around the hinge with the mounting frame 15, and at the same time the torsion spring accumulates force, after the push rod 7 retracts, the second mounting frame 12 is reset under the elastic force of the torsion spring, collides with the mounting frame 15, and shakes off the dust on the second filter 13, thereby preventing the second filter 13 from being blocked.

[0025] Working principle of the utility model: when in use, the device is connected to electricity and connected to an external PLC control unit, and the PLC control unit can control the start and stop of the solenoid valve 4, the negative pressure fan 8 and the push rod 7;

[0026] Move the device to a designated position, align the dust hood 5 with the position where the putty dust escapes, control the negative pressure fan 8 to work, and form a negative pressure at the dust hood 5 through the bellows 6, so that the escaped putty dust is sucked into the chassis 1, and the dust is filtered out by the second filter 13 and the first filter 10, and the clean air is discharged from the chassis 1, forming a cycle;

[0027] Under the condition of long-term operation, more dust adheres to the second filter screen 13, which affects the collection of dust. At this time, the control push rod 7 works, and drives the pressing frame 11 to slide on the first mounting frame 9 through the connecting plate 14. The bottom of the pressing frame 11 presses the second mounting frame 12 to rotate around the hinge with the mounting frame 15. The torsion spring accumulates force, and the push rod 7 quickly resets. The second mounting frame 12 is reset under the elastic force of the torsion spring, so that the second mounting frame 12 and the mounting frame 15 collide with each other, and at the same time drive the second filter screen 13 to vibrate, and shake off the dust adhered to the second filter screen 13, or make the dust move to the hinge between the second mounting frame 12 and the mounting frame 15 driven by the wind, so as to avoid the second filter screen 13 being completely blocked and affecting the collection of dust.

[0028] After the work is completed, the box door 2 can be opened to clean the inside of the box 1, or the solenoid valve 4 can be opened to vibrate the second filter screen 13 to discharge the dust from the discharge port.

[0029] The electromechanical connection involved in the present utility model is a common means used by those skilled in the art, and technical inspiration can be obtained through a limited number of tests, which belongs to common knowledge.
