DETAILED DESCRIPTION

[0020] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other.

A plurality of mounting holes 42 for mounting dust bags 41 are provided on the support base 4. A plurality of mounting holes 42 surround the support base 4. The seats 4 are evenly spaced around the circumference; the air intake chamber 2 and the exhaust chamber 3 are connected through multiple mounting holes 42; a rotating mechanism 5 is provided within the machine body 1 to drive the support seat 4 to rotate; an isolation device 6 is provided on the machine body 1 to isolate the dust bags 41; the isolation device 6 includes an inspection chamber 63 with an access door 631, a first arc-shaped isolation plate 623 that can be rotated within the inspection chamber 63 to isolate and open and close the air intake chamber 2, and a second arc-shaped isolation plate 613 that can be rotated within the inspection chamber 63 to isolate and open and close the exhaust chamber 3. By designing an isolation device that can isolate dust bags one by one, the dust bags can be isolated and removed and installed one by one, ensuring continuous operation of the equipment, reducing the frequency of equipment shutdowns for maintenance, ensuring continuous operation of the equipment, and lowering maintenance costs.

[0022] Specifically, the rotating mechanism 5 includes a slide groove 51 arranged on the side wall of the body 1 to support the rotation of the support seat 4, and a driving device 52 to drive the support seat 4 to rotate; the driving device 52 includes a first driving motor 521 with a reducer arranged on the top of the body 1, and a gear ring 43 arranged on the support seat 4; a driving gear 522 matching the gear ring 43 is installed on the output shaft of the first driving motor 521.

[0023] Specifically, the isolation device 6 includes an upper isolator 61 and a lower isolator 62, respectively disposed on the upper and lower sides of the support base 4. The lower isolator 62 includes a first electric actuator 621 fixed to the bottom of the maintenance compartment 63, a first connecting frame 622 fixed to the output shaft of the first electric actuator 621 extending into the maintenance compartment 63, and a first isolation plate 623 fixed to the first connecting frame 622. The upper isolator 61 includes a second electric actuator 611 fixed to the top of the maintenance compartment 63, a second connecting frame 612 fixed to the output shaft of the second electric actuator 611 extending into the maintenance compartment 63, and a second isolation plate 613 fixed to the second connecting frame 612. By designing two actuators that can move synchronously, the two isolation plates are driven to rotate simultaneously, isolating the maintenance compartment and enabling the removal and installation of the dust bag.

[0024] Specifically, the lower side of the support seat 4 is provided with a plurality of lower slides 45 for guiding the sliding of the first isolation plate 623; the lower slides 45 are arranged around the dust bag 41 and cooperate with the side wall of the body 1 to form a protection for the dust bag 41; the upper side of the support seat 4 is provided with a plurality of upper slides 44 for guiding the sliding of the second isolation plate 613; the upper slides 44 are arranged around the dust bag 41 and cooperate with the side wall of the body 1 to form a protection for the dust bag 41.

[0025] Specifically, the body 1 is equipped with a dust suppression device 7 that strikes the outer wall of the dust bag 41. The dust suppression device 7 includes a second drive motor 71 fixed to the top of the body 1. A mounting rod 72 is fixed to the output shaft of the second drive motor 71. The mounting rod 72 is provided with multiple, spaced-apart mounting seats 73. The mounting seats 73 include multiple, spaced-apart suspension rods 74. By designing a dust suppression device that strikes the dust bag, dust accumulated in the dust bag is regularly knocked away, further extending the service life of the dust bag and reducing maintenance frequency.

[0026] Specifically, the flexible suspension strip 75 is fixed to the end of the suspension rod 74 .

[0027] Specifically, the suspension rods 74 on two adjacent mounting seats 73 are vertically staggered.

[0028] Working principle: During the dust removal work, the air flows into the air intake bin 2 from the air intake pipe 11, passes through the dust bag 41 and is filtered, then enters the exhaust bin 3 from the mounting hole 42 and is discharged from the exhaust pipe 12. After a period of use, the dust reduction device 7 is started regularly, and the second drive motor 71 drives the mounting rod 72 to rotate, driving the flexible cantilever 75 to fly and hit the outer wall of the dust bag 41. The multi-layer staggered suspension bars 75 staggeredly hit the outer wall of the dust bag 41, quickly cleaning the dust accumulated on the bag 41, reducing the risk of dust clogging the dust bag 41 and affecting the filtration efficiency. The dust reduction device 7 is turned off after a period of use; when the bag 41 needs to be replaced, the lower isolator 62 and the upper isolator 61 are started at the same time, driving the second isolation plate 613 and the first isolation plate 623 to enter the corresponding lower slide 45 and upper slide 44 at the same time and rotate to the side away from the inspection door 631. The second isolation plate 613 and the first isolation plate 623 cooperate with the side wall of the body 1 to isolate the single dust bag 41 After the dust bag 41 is replaced, the inspection door 631 is closed again to form a sealed chamber of the machine body 1, and the lower isolator 62 and the upper isolator 61 are started to drive the second isolation plate 613 and the first isolation plate 623 to separate from the corresponding lower slide 45 and upper slide 44, and enter the inspection chamber 63 near the inspection door 631 for storage. After the first drive motor 521 is started to drive the support seat 4 to rotate the preset angle, the adjacent dust bag 41 rotates to a position close to the inspection chamber 63, and the above operation is repeated to isolate and replace the dust bag 41, so as to ensure the uninterrupted overall dust removal work and realize the timely replacement of the dust bag 41 to ensure the continuous operation of the equipment.
