[0019] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings.

[0020] Depend on Figures 1 to 6 It is known that a waste gas purification and dust removal device includes a body 1, a dust collection bag 2 inside the body 1, an air inlet 3 at the top of the body 1, and an exhaust port 4 at the bottom of the body 1 located in the middle. Waste gas enters the body 1 through the air inlet 3, is purified by the dust collection bag 2, and is discharged through the exhaust port 4. The dust collection bag 2 is equipped with a lifting back-blowing mechanism, which includes multiple air blowing nozzles 5. The air blowing nozzles 5 back-blow the dust collection bag 2, causing the dust on the outside of the dust collection bag 2 to fall off.

[0021] In practical use, this utility model

[0022] This dust removal device is installed in the exhaust gas purification system. The exhaust gas enters the machine body 1 from the air inlet 3, is filtered and purified by the dust bag 2, and is discharged from the exhaust port 4 to enter the next purification process.

[0023] In this device, exhaust gas passes through the dust collection bag 2 from the outside to the inside for filtration and purification. A back-blowing mechanism is installed inside the dust collection bag 2, which can back-blow the dust attached to the outside of the dust collection bag 2 from the inside, reducing dust adhesion, maintaining the filtration capacity of the dust collection bag 2, thereby improving the purification and dust removal efficiency and reducing the workload of the staff.

[0024] Multiple support legs 6 are provided at the bottom of the body 1 to support the body 1 and keep the body 1 stable.

[0025] The bottom of the machine body 1 is provided with an annular collection chamber 7, and the bottom of the collection chamber 7 is provided with multiple slag discharge ports 8. The top of the collection chamber 7 is provided with a partition 9, and the partition 9 is densely covered with first through holes 10. A baffle 11 is rotatably provided on the partition 9, and the baffle 11 is densely covered with second through holes 12 that cooperate with the first through holes 10. After the baffle 11 is rotated, the first through holes 10 and the second through holes 12 are aligned, so that the inside of the machine body 1 is connected to the collection chamber 7. After the baffle 11 is rotated again, the first through holes 10 and the second through holes 12 are completely misaligned, so that the inside of the machine body 1 is formed into a closed chamber. A gear ring 13 is provided on the outer side above the baffle 11. A gear 14 that meshes with the gear ring 13 is rotatably provided on the side wall of the machine body 1. The gear 14 is driven by a control motor 15.

[0026] The collection chamber 7 is used to collect the filtered dust. The mutual rotation of the baffle 11 and the partition 9 allows the collection chamber 7 to be connected to or disconnected from the interior of the machine body 1. When purifying and removing dust from the exhaust gas, the baffle 11 rotates, and the first through hole 10 and the second through hole 12 are completely aligned, connecting the collection chamber 7 to the interior of the machine body 1. The exhaust gas is purified by the dust collection bag 2 and discharged from the exhaust pipe 20. The filtered dust falls into the collection chamber 7 through the first through hole 10 and the second through hole 12 for collection. When it is necessary to clean the dust, the baffle 11 is rotated, so that the positions of the first through hole 10 and the second through hole 12 are completely offset, and the collection chamber 7 is not connected to the interior of the machine body 1. At this time, the slag discharge port 8 is opened to clean out the collected dust. This does not affect the purification of the exhaust gas, does not require machine shutdown, simplifies the workflow, and improves the purification efficiency of the exhaust gas.

[0027] The machine body 1 has a lead screw 16 rotatably mounted inside, and parallel guide rods 17 are mounted on both sides of the lead screw 16. The back-blowing mechanism includes a fixed plate 18 that is threadedly connected to the lead screw 16. The guide rods 17 pass through the fixed plate 18. Multiple air blowing nozzles 5 are evenly distributed around the circumference of the fixed plate 18. A lifting motor 19 that drives the lead screw 16 is fixed on the top of the machine body 1. An exhaust pipe 20 is mounted on the outside of the exhaust port 4. An air compressor 21 that connects to the air blowing nozzles 5 is mounted on the top of the machine body 1. The air intake pipe of the air compressor 21 connects to the exhaust pipe 20.

[0028] The back-blowing mechanism uses the lifting motor 19 to operate the fixed plate 18 to reciprocate up and down, which in turn drives the air nozzle 5 to reciprocate up and down, back-blowing the dust bag 2 so that the dust attached to its exterior is blown off, thus maintaining the purification efficiency.

[0029] The air compressor 21 is connected to the air blowing nozzle 5 through a bellows. The air used for blowing is the air inside the exhaust pipe 20, which is filtered and purified air. Using it for backflushing will not have an adverse effect on the purified gas, thus ensuring the purification effect.

[0030] Compared with the prior art, this utility model has the following advantages: a liftable back-blowing mechanism is set inside the dust collector bag to back-blow the dust collector bag and blow off the dust attached to its outside, thereby maintaining the filtration and purification efficiency of the dust collector bag, thereby reducing the frequency of downtime maintenance and improving the purification efficiency of exhaust gas; and it also greatly reduces the workload of staff, reduces labor intensity, and protects the personal safety of staff.
