DETAILED DESCRIPTION

[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0032] like Figures 1 to 8 As shown, a pulse bag-type dust collector comprises a box body 1, a transverse partition 2 is welded inside the box body 1, a plurality of longitudinal partitions 3 evenly spaced laterally are fixedly installed inside the box body 1 below the transverse partition 2, the plurality of longitudinal partitions 3 divide the inner cavity of the box body 1 below the transverse partition 2 into a plurality of dust removal chambers 4 evenly spaced left and right, an ash hopper 5 corresponding to the dust removal chamber 4 is fixedly installed on the bottom of the box body 1 by bolts, an ash discharge pipe is provided at the lower end of the ash hopper 5, a discharge valve is provided on the ash discharge pipe, the lower end of the dust removal chamber 4 is connected with the corresponding ash hopper 5, so that each dust removal chamber 4 can be independently pulse cleaned.

[0033] like Figure 3 As shown, a plurality of air holes 6 are evenly distributed in a rectangular array on the partition 2, and the number of rows of the air holes 6 corresponds to the dust removal chamber 4. A dust bag 7 is installed in the dust removal chamber 4 below the air holes 6. Each dust removal chamber 4 is respectively connected to an air intake mechanism, and an exhaust pipe 8 is provided on the left side wall of the box body 1 above the partition 2.

[0034] When the equipment is running, the dust-containing gas enters into multiple dust removal chambers 4 through the air intake mechanism. When the dust-containing gas passes through the air vents 6 upward, the dust in the gas is blocked by the dust removal bags 7. Finally, the gas filtered by the dust removal bags 7 is discharged through the exhaust pipe 8.

[0035] like Figure 4 and Figure 5As shown, a mounting frame 9 driven by a power mechanism to move laterally is provided in the box body 1 above the diaphragm 2. Specifically, a guide rod 10 extending laterally is fixedly installed in the box body 1 above the diaphragm 2 by bolts, and a sleeve 11 matching the guide rod 10 is fixedly installed on the mounting frame 9 by bolts, providing a guide for the left and right movement of the mounting frame 9; the power mechanism is specifically a screw rod 12 arranged parallel to the guide rod 10, the left end of the screw rod 12 is rotatably installed on the left side wall of the box body 1 through a bearing, and the right end of the screw rod 12 is connected to the rotating shaft of the driving motor 13 through a coupling, and the driving motor 13 is installed on the right side of the box body 1 by bolts, and a screw nut 14 matching the screw rod 12 is fixedly installed on the mounting frame 9 by bolts. The screw rod 12 is driven to rotate by the driving motor 13, and the screw rod 12 acts on the screw nut 14 to drive the mounting frame 9 to move left and right along the guide rod 10, so as to adjust the position of the mounting frame 9 and the air intake cover 15.

[0036] An air intake hood 15 for covering a plurality of air holes 6 corresponding to one of the dust removal chambers 4 is provided at the bottom of the mounting frame 9. The air intake hood 15 is driven to rise and fall by a telescopic component. The telescopic component is specifically an electric push rod 16 installed on the mounting frame 9 by bolts. The output end of the electric push rod 16 extends downward and is fixedly connected to the top of the air intake hood 15 by bolts. The air intake hood 15 is raised or lowered by the telescopic movement of the electric push rod 16.

[0037] The bottom of the air intake hood 15 is opened, and the top of the box body 1 is provided with a pulse air intake pipe 17. The top of the air intake hood 15 is connected to the pulse air intake pipe 17 through a long bellows 37. The lower end of the long bellows 37 is fixedly installed on the top of the air intake hood 15 by bolts. A through hole connected to the lower end of the long bellows 37 is provided on the top wall of the air intake hood 15. The upper end of the long bellows 37 is fixedly installed on the inner side of the top wall of the box body 1 by bolts and is connected to the lower end of the pulse air intake pipe 17. The upper end of the pulse air intake pipe 17 is connected to a pulse blowing mechanism.

[0038] In the initial state, the air intake hood 15 is in a raised state and does not contact the top of the diaphragm 2. At this time, the dust bags 7 in the multiple dust removal chambers 4 are in a working state of filtering dust. When it is necessary to perform pulse cleaning on the dust removal bags 7, the power mechanism is first used to drive the mounting frame 9 and the air intake hood 15 to move left and right, so that the air intake hood 15 moves to the top of the multiple air holes 6 corresponding to one of the dust removal chambers 4, and the electric push rod 16 is extended to drive the air intake hood 15 to descend and fit on the top of the diaphragm 2, and the multiple air holes 6 of the corresponding dust removal chamber 4 are covered by the air intake hood 15, and then the pulse spray mechanism is started, and the high-pressure gas enters the air intake hood 15 through the pulse air intake pipe 17 and the long corrugated pipe 37 and performs pulse cleaning on the multiple dust removal bags 7 in the corresponding dust removal chamber 4.

[0039] After the dust removal bag 7 of one dust removal chamber 4 is cleaned, the electric push rod 16 is retracted to drive the air intake cover 15 to be lifted and reset, and the power mechanism drives the mounting frame 9 and the air intake cover 15 to move to the top of the next dust removal chamber 4, and the dust removal bags 7 in multiple dust removal chambers 4 are cleaned in turn. When the dust removal bag 7 in one dust removal chamber 4 is cleaned, the dust removal bags 7 in other dust removal chambers 4 can perform dust removal work normally, without completely shutting down the equipment, and the dust removal efficiency is higher.

[0040] like Figure 2 and Figure 7 As shown, the air intake mechanism includes a bellows 19 fixedly installed on the rear side of the box body 1 by bolts, and a plurality of isolation plates 20 evenly spaced on the left and right are welded inside the bellows 19, and the plurality of isolation plates 20 divide the inner cavity of the bellows 19 into a plurality of air inlet chambers 21, and the air inlet chambers 21 correspond to the dust removal chambers 4 one by one, and the air inlet chambers 21 are located on the rear side of the corresponding dust removal chambers 4, and an air inlet 22 connecting the corresponding air inlet chamber 21 and the dust removal chamber 4 is provided on the rear side wall of the box body 1; the air intake mechanism also includes a main air inlet pipe 23, and the main air inlet pipe 23 is connected to the plurality of air inlet chambers 21 through air inlet branch pipes 24, and one end of the air inlet branch pipe 24 away from the main air inlet pipe 23 is fixedly connected to the rear side of the box body 1 by bolts and communicated with the corresponding air inlet chamber 21.

[0041] Each air inlet branch pipe 24 is provided with an air valve, which is in a normally open state. During daily operation, dust-containing gas enters the corresponding dust removal chamber 4 through the main air inlet pipe 23, the air inlet branch pipe 24 and the air inlet chamber 21, and is dusted synchronously by the dust removal bags 7 in the multiple dust removal chambers 4. When pulse cleaning is performed on the dust removal bags 7 in one of the dust removal chambers 4, the multiple air holes 6 of the corresponding dust removal chamber 4 are covered by the air inlet cover 15, and the air valve on the air inlet branch pipe 24 corresponding to the corresponding dust removal chamber 4 is closed, thereby improving the cleaning effect of the dust removal bags 7.

[0042] A rotating rod 25 extending horizontally forward and backward is rotatably installed in the dust removal chamber 4. The front end of the rotating rod 25 is rotatably installed on the front side wall of the dust removal chamber 4 through a bearing. A support plate 36 is also fixedly installed on the inner side of the rear side wall of the dust removal chamber 4 through bolts. The rotating rod 25 is rotatably connected to the support plate 36 through a bearing to improve the stability of the rotation of the rotating rod 25. The rotating rod 25 is connected to the power device. Specifically, the rear end of the rotating rod 25 extends into the corresponding air inlet chamber 21. The power device is an impeller hub 26 fixedly installed on the rear end of the rotating rod 25 through bolts. The impeller hub 26 is welded with a fan blade 27. When the dust-containing gas enters the air inlet chamber 21 through the main air inlet pipe 23 and the air inlet branch pipe 24, the dust-containing gas will blow the fan blade 27 to drive the rotating rod 25 to rotate.

[0043] A beating plate 28 for beating the lower end of the dust bag 7 is fixedly mounted on the rotating rod 25, and a mounting sleeve is provided at one end of the beating plate 28, which is fixedly mounted on the rotating rod 25 by bolts. In this embodiment, a plurality of dust bags 7 located in the same dust removal chamber 4 are evenly spaced front and back along the length direction of the corresponding rotating rod 25, and the rotating rod 25 is located directly below the plurality of dust bags 7. The number of beating plates 28 corresponds to the number of dust bags 7. The rotating rod 25 drives the beating plates 28 to repeatedly beat the lower end of the corresponding dust bag 7, thereby causing the dust bag 7 to vibrate, making it difficult for dust to adhere to the outer side of the dust bag 7, thereby effectively extending the cleaning cycle of the dust bag 7.

[0044] The flapping board 28 is a flexible flapping board, and the flapping board 28 can be made of rubber or silicone material to prevent the flapping board 28 from damaging the dust bag 7.

[0045] The rear end of the rotating rod 25 is directly opposite to the air outlet end of the corresponding air inlet branch pipe 24, which is conducive to the dust-containing gas efficiently driving the rotating rod 25 to rotate.

[0046] like Figure 8 As shown, a short bellows 29 is connected between the upper end of the dust bag 7 and the corresponding air vent 6, and an upper connecting plate 30 is fixedly installed on the outer side of the upper end of the short bellows 29 by bolts. The upper connecting plate 30 is fixedly installed on the bottom of the diaphragm 2 by bolts, and the upper end of the short bellows 29 is connected with the corresponding air vent 6; a lower connecting plate 31 is fixedly installed on the outer side of the lower end of the short bellows 29 by bolts, and the upper end of the dust bag 7 is clamped or detachably installed on the bottom of the lower connecting plate 31 by bolts and is connected with the lower end of the short bellows 29, so that the dust bag 7 can move up and down within a certain range. A vertically extending sliding rod 32 is fixedly installed at the bottom of the transverse partition 2 or the bottom of the upper connecting plate 30. A thread is provided on the outer side of the upper end of the sliding rod 32 to facilitate connection and fixation. The lower connecting plate 31 is vertically slidably sleeved on the sliding rod 32. A stopper 33 is integrally formed at the lower end of the sliding rod 32. Springs 34 are respectively sleeved on the sliding rods 32 on the upper and lower sides of the lower connecting plate 31. When the flapping plate 28 flaps the lower end of the dust bag 7, the amplitude of the up and down vibration of the dust bag 7 can be increased.

[0047] like Figure 6 As shown, a sealing strip 35 is clamped or bonded to the bottom edge of the air inlet cover 15 to prevent air leakage from the bottom edge of the air inlet cover 15 when the dust removal bag 7 is pulse-cleaned.

[0048] The above shows and describes the basic principles, main features and advantages of the present invention.
