Description

Technical Field

[0001] The invention relates to the field of bag dust removal, and in particular to a bag dust collector and a dust discharge valve. Background Art

[0002] The bag filter is a dry dust filtering device. It is suitable for capturing fine, dry dust. The dust bag inside is made of textile filter cloth or non-textile felt, and uses the filtering effect of fiber fabric to filter dust-containing gas. When the bag filter is used for a long time, a large amount of dust will adhere to the dust bag. In order to avoid affecting the passage of gas, the dust bag needs to be cleaned. However, most of the existing cleaning methods use air blowing to clean, that is, blowing air into the dust bag to blow the dust on the surface of the dust bag off. This cleaning method has a certain blocking effect on the blown gas during blowing, resulting in a reduction in the force of the gas blowing on the dust, so that all the attached dust cannot be blown off, resulting in some dust remaining on the surface of the dust bag after cleaning, resulting in poor cleaning effect.

The front lower part of the device shell 1 is fixedly connected with an air intake pipe 3, and the air intake pipe 3 allows dust-containing gas to enter. The upper side of the device shell 1 is fixedly connected with an exhaust pipe 4, and the exhaust pipe 4 allows the filtered dust-containing gas to be discharged. The exhaust pipe 4 is located in front of the servo push cylinder 5.

[0019] A card slot 35 is formed on the outer surface of the swing arm 12, and the brush handle of the brush plate 13 fits inside the card slot 35. The card slot 35 serves to clamp the brush plate 13. Two supporting shells 14 are symmetrically fixedly installed on the upper end of the swing arm 12. A fixing column 30 is coaxially arranged inside the supporting shell 14. The supporting shell 14 serves to support the fixing column 30. The fixing column 30 extends from the upper and lower ends of the supporting shell 14, and the fixing column 30 serves to fix the brush plate 13 in the card slot 35.

[0021] The swinging member includes an axle seat 29 fixedly mounted on the lower end of the push rod 7, one end of the axle seat 29 is rotatably mounted with a No. 1 bearing shaft 23, and the axle seat 29 plays the role of carrying the No. 1 bearing shaft 23 and the No. 2 bearing shaft 24. A top ear 21 extends from the upper edge of the No. 1 bearing shaft 23, and a connecting frame 20 is rotatably mounted on the end of the top ear 21. The top ear 21 can drive the connecting frame 20 to move, and an L-shaped top frame 19 is rotatably mounted on the end of the connecting frame 20. The connecting frame 20 can push the L-shaped top frame 19 to move the L-shaped top frame 19 up and down. The concave frame 15 is fixedly installed at the end of the L-shaped top frame 19, and the concave frame 15 is slidably connected to the push rod 7. The concave frame 15 plays a role in bearing the swing rod 12. The two swing rods 12 are rotatably connected to the two ends of the concave frame 15 respectively. The top ear 21 on the No. 1 load-bearing shaft 23 can rotate rapidly with the cooperation of the large gear 10 and the small gear 22, thereby driving the connecting frame 20 to move to push and pull the concave frame 15, so that the brush plate 13 can continuously swing up and down during the downward movement, so as to clean the same area on the dust bag 9 multiple times.

[0022] The outer surface of the push rod 7 is coaxially inlaid with a frame sleeve 28, and a protruding frame 18 is fixedly installed on the side of the frame sleeve 28. The frame sleeve 28 serves to connect the protruding frame 18. A square guide column 37 is fixedly installed at the end of the protruding frame 18. The protruding frame 18 serves to carry the square guide column 37. The square guide column 37 passes through the middle of the upper end of the concave frame 15, and the square guide column 37 serves to linearly guide the concave frame 15. The square guide column 37 slides with the concave frame 15. The front ends of the two swing rods 12 are coaxially inlaid with pulleys 17, and the pulleys 17 serve to connect the synchronous belt 16. The synchronous belt 16 is connected between the two pulleys 17. The synchronous belt 16 serves to allow the two swing rods 12 to rotate synchronously. The synchronous belt 16 can be covered with an outer shell to prevent dust from adhering to the synchronous belt 16 and affecting the transmission. Because dust prevention by covering with an outer shell is a prior art and has been widely used, it is not elaborated in detail here and is not shown in the figure.

[0023] The other end of the shaft seat 29 is rotatably mounted with a No. 2 load-bearing shaft 24, and a rotating gear 25 is coaxially inlaid on the front end of the No. 2 load-bearing shaft 24. The No. 2 load-bearing shaft 24 serves to carry the rotating gear 25. A load-bearing tooth plate 11 is meshed on one side of the rotating gear 25, and the upper end of the load-bearing tooth plate 11 is fixed to the sealing plate 8. The cooperation between the load-bearing tooth plate 11 and the rotating gear 25 enables the No. 2 load-bearing shaft 24 to rotate. A large gear 10 is coaxially inlaid on the outer surface of the No. 2 load-bearing shaft 24, and the large gear 10 is located behind the rotating gear 25. A small gear 22 is coaxially inlaid on the outer surface of the No. 1 load-bearing shaft 23, and the small gear 22 is located behind the top ear 21. The small gear 22 is meshed with the large gear 10, and the cooperation between the small gear 22 and the large gear 10 enables the No. 1 load-bearing shaft 23 to rotate faster.

[0024] The front end of one of the swing rods 12 is coaxially inlaid with a swing gear 36, and the swing gear 36 is located in front of the pulley 17. A swing tooth plate 26 is meshed on one side of the swing gear 36. The cooperation between the swing gear 36 and the swing tooth plate 26 can allow the swing rod 12 to reciprocate. A plate frame 27 is fixedly installed in the middle of the side of the swing tooth plate 26. During the continuous up and down swinging of the brush plate 13, the swing gear 36 will roll on the swing tooth plate 26 to drive the swing rod 12 to continuously reciprocate, that is, the brush plate 13 cleans the dust bag 9 in a fast arc swinging manner to promote the falling of dust. It plays the role of fixing the swinging tooth plate 26. The end of the plate frame 27 is fixed to the push rod 7. The above-mentioned gear part can be covered by a gear housing outside the gear to prevent dust from adhering to the gear and affecting the transmission. At the same time, the gear and the tooth plate part can first be covered by a gear housing outside the gear, so as to cover the gear, and a telescopic dust cover can be installed between the gear housing and the tooth plate to cover the tooth plate, so that the gear and the tooth plate can prevent dust from adhering to the gear and the tooth plate while stabilizing the transmission. Because the above-mentioned dust-proof covering method is a prior art and has been widely used, it is not elaborated here and is not shown in the figure.

[0025] When in use, the dust-containing gas is introduced into the interior of the device shell 1 through the air inlet pipe 3. At this time, the dust-containing gas passes through the dust bag 9 to block the dust in the gas through the dust bag 9, and the gas after dust removal is discharged through the exhaust pipe 4. When there is a lot of dust attached to the surface of the dust bag 9, the servo push cylinder 5 can be driven to move the push rod 7 on the lifting frame 6 downward, and the two brush plates 13 move downward synchronously to clean the dust on both sides of the dust bag 9. In this process, the rotating gear 25 will roll on the bearing tooth plate 11 to drive the large gear 10 on the second bearing shaft 24 to rotate, so that the top ear 21 on the first bearing shaft 23 can rotate quickly under the cooperation of the large gear 10 and the small gear 22. Then, the connecting frame 20 is driven to move to push and pull the concave frame 15, so that the brush plate 13 can continuously swing up and down during the downward movement, so as to clean the same area on the dust bag 9 multiple times, thereby increasing the cleaning force. At the same time, the swing gear 36 will roll on the swing tooth plate 26 during the continuous up and down swinging of the brush plate 13, so as to drive the swing rod 12 to continuously rotate back and forth, that is, the brush plate 13 cleans the dust bag 9 in a rapid circular arc swinging manner to promote the falling of dust, so that the dust on the dust bag 9 can be fully removed, and the removed dust will fall down to the bottom of the shell 1, and then the ash discharge valve 2 will be opened to discharge the dust at the bottom of the shell 1.
