Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a bag dust collector with uniform air intake. Background Art

[0002] A bag filter is a dry dust filtration device suitable for capturing fine, dry, non-fibrous dust. Made of textile filter cloth or non-woven felt, the filter bags utilize the filtration properties of the fabric to filter dust-laden air. When dust-laden air enters the bag filter, large, high-density dust particles settle due to gravity and fall into the hopper. Finer dust particles are retained as they pass through the filter material, resulting in purification.

[0003] Existing bag-type dust collectors have uneven air intake, which can easily affect dust removal efficiency and stability. Furthermore, after a bag-type dust collector has been in use for a long time, dust accumulates at the bottom of the dust collection bin, which can easily clog the dust collection bags and affect dust removal efficiency. Therefore, a bag-type dust collector with uniform air intake is proposed. Summary of the Invention

[0004] The present invention aims to solve the technical problems that the air intake of the existing bag dust collector is uneven, which easily affects the dust removal effect and stability, and dust accumulates at the bottom of the dust collecting bin after the bag dust collector has been used for a long time, which easily clogs the dust collection bag and affects the dust removal effect. The present invention provides a bag dust collector with uniform air intake.

[0005] The technical solution adopted by the present invention to solve its technical problem is:

[0006] A bag dust collector with uniform air intake, comprising a dust removal bin, a wind speed self-regulating mechanism, a synchronous vibration cleaning mechanism and an automatic discharging mechanism;

[0007] The dust collection bin is cylindrical, the top plate of the dust collection bin is fixedly provided with an air outlet bin, the bottom of the dust collection bin is fixedly provided with a dust collecting bin, the dust collecting bin is conically provided, the dust collecting bin is coaxially arranged, the outer wall of the dust collection bin is fixedly provided with a mounting bracket, reinforcing ribs are fixedly provided between the side walls of adjacent mounting brackets, the mounting bracket is parallel to the axis of the dust collection bin, the reinforcing ribs are perpendicular to the mounting bracket, the bottom of the mounting bracket is fixedly provided with a base, the top pipeline of the right side wall of the dust collection bin is connected to the air inlet duct, and the pipeline of the left side wall of the air outlet bin is connected to the air outlet duct, the wind speed self-adjusting mechanism is arranged inside the air inlet duct, the synchronous vibration cleaning mechanism is arranged inside the air outlet bin, and the automatic discharging mechanism is arranged at the bottom of the dust collection bin. During use, the wind speed self-adjusting mechanism can keep the air flow velocity flowing into the dust collection bin stable and uniform, avoiding unstable dust removal effect caused by uneven wind speed. When the airflow flows, it drives the synchronous vibration cleaning mechanism to periodically clean the inside of the dust collection bin, avoiding the dust bag from being blocked and affecting the filtering effect. When the synchronous vibration cleaning mechanism is running, it drives the automatic discharging mechanism to automatically discharge the dust inside the dust collection bin, realizing automatic discharging and reducing manpower waste.

[0008] Furthermore, the wind speed self-regulating mechanism includes a baffle, which is arranged inside the air inlet duct, the baffle is arranged perpendicular to the axis of the air inlet duct, and the side wall of the baffle facing the dust removal bin is connected to a first hydraulic rod, the first hydraulic rod is arranged perpendicular to the baffle, and the other end of the first hydraulic rod is fixedly connected to a mounting platform, and a plurality of mounting rods are fixedly arranged between the mounting platform and the inner wall of the air inlet duct, the mounting rods are arranged perpendicular to the first hydraulic rod, and the plurality of mounting rods are evenly arranged on the outside of the side wall of the mounting platform, and a first spring is connected between the baffle and the mounting platform, and the first spring is arranged around the outside of the first hydraulic rod. When in use, the airflow flows into the dust removal bin along the air inlet duct, and the baffle is then pushed toward the dust removal bin, causing the first hydraulic rod to shorten and the first spring to compress, thereby generating an elastic force in the opposite direction on the baffle.

[0009] Furthermore, the inner side wall of the air inlet duct is rotatably connected to a plurality of movable baffles, which are evenly arranged along the axis of the air inlet duct and arranged in a fan shape. The movable baffles are rotatably connected to a second hydraulic rod toward one side of the inner wall of the air inlet duct, and the other end of the second hydraulic rod is rotatably connected to the inner wall of the air inlet duct. When the second hydraulic rod is extended, it drives the movable baffles to open, thereby reducing the flow area inside the air inlet duct. When the gas flow rate in the air inlet duct increases, the thrust applied to the baffle increases, the movement amplitude of the first and second hydraulic rods increases, and the opening amplitude of the movable baffles increases. Conversely, when the gas flow rate in the air inlet duct decreases, the baffle returns to its original position under the elastic force of the first spring, and the movable baffles also return to their original position, thereby maintaining a stable and uniform gas flow rate inside the air inlet duct and preventing unstable dust removal effect caused by uneven wind speed.

[0010] Furthermore, a first hydraulic chamber is provided within the end of the first hydraulic rod away from the baffle, and the first hydraulic chamber is filled with hydraulic oil. A second hydraulic chamber is provided within the end of the second hydraulic rod away from the movable baffle, and the first and second hydraulic chambers are connected by a connecting pipe.

After the airflow flows into the dust removal bin, it first flows into the interior of the air inlet tube, at which time the blades begin to rotate under the action of the wind, driving the rotating shaft to start rotating, and when the rotating shaft rotates, it drives the first driving wheel to start rotating.

[0012] Furthermore, a plurality of connecting heads are fixedly provided at the bottom of the partition, a dust bag is provided at the bottom of the connecting head, a counterweight is connected to the bottom of the dust bag, a connecting block is fixedly provided on the outside of the side wall of the air outlet bin facing the air inlet pipe, a high-pressure gas cylinder is fixedly provided on the outside of the connecting block, the inner pipeline of the high-pressure gas cylinder is connected to a diversion pipe, the inner end of the diversion pipe extends to the interior of the air outlet bin, the bottom pipeline of the diversion pipe is connected to a plurality of cleaning pipes, the bottom end pipeline of the cleaning pipe is connected to a plurality of nozzles, the nozzles are provided on the top of the connecting head, and the number and position of the nozzles match the connecting head. After the air flow flows out of the bottom of the air inlet tube, the larger dust particles inside it fall into the dust collecting bin, and the remaining gas is filtered by the dust removal bag and passes through the connector into the air outlet bin and flows out along the air outlet pipe. During cleaning, the high-pressure gas inside the high-pressure gas cylinder flows along the diversion pipe into the cleaning pipe and then is sprayed into the dust removal bag at high speed along the nozzle. The dust removal bag vibrates violently under the action of high pressure, thereby shaking off the dust on its surface into the dust collecting bin.

[0013] Furthermore, a first valve is provided in the middle of the diverter pipe, a stopper is fixedly provided on the top of one side of the first valve facing the air inlet pipe, a movable switch is movably provided on the other side of the top of the first valve, a second spring is connected between the movable switch and the stopper, a connecting shaft is rotatably provided on the top of the side of the air outlet chamber away from the air inlet pipe, a first driven wheel is provided on the top of the connecting shaft, a transmission chain is meshed between the first driven wheel and the first driving wheel, the diameter of the first driven wheel is larger than the diameter of the first driving wheel, a cam is connected to the bottom end of the connecting shaft, and the side wall of the cam abuts against the movable switch. When the first driving wheel rotates, the first driven wheel is driven by the transmission chain meshed with it to start rotating, so that the connecting shaft starts rotating, and when the connecting shaft rotates, the cam at the bottom starts rotating. When the cam rotates, it periodically pushes the movable switch to move in the direction of the stopper, so that the first valve is periodically opened, thereby achieving periodic cleaning of the dust bag, effectively preventing the dust bag from being clogged by dust and affecting the filtering effect.

[0014] Furthermore, the automatic discharge mechanism includes an upper slot, the upper slot being formed on the top of the air outlet bin and located on the top of the movable switch. A push rod is fixedly provided on the top of the movable switch, the push rod being perpendicularly arranged to the top of the air outlet bin, the top end of the push rod extending through the upper slot to the top of the air outlet bin, and the push rod being slidably connected to the upper slot.

[0015] Furthermore, a second valve is provided at the input end of the air inlet pipe. A toggle switch is rotatably provided at the top of the second valve. An upper connecting rod is fixedly provided at the top of the toggle switch. A cross bar is fixedly provided between the top end of the upper connecting rod and the top rod. The cross bar is perpendicularly arranged to the upper connecting rod and the top rod. A reinforcing rod is fixedly provided at the connection between the cross bar, the upper connecting rod, and the top rod. When the top rod moves, the cross bar starts to move, causing the upper connecting rod to start moving. When the upper connecting rod moves, the toggle switch at the bottom rotates periodically, causing the second valve to close during cleaning, thereby preventing the inflow of airflow from affecting the cleaning effect of the high-pressure gas.

[0019] 2. The bag-type dust collector with uniform air intake of the present invention is provided with a wind speed self-adjusting mechanism, which can drive the movable baffle to open when the second hydraulic rod is extended, so that the flow area inside the air inlet duct is reduced.

[0027] The following will clearly and completely describe the concept and technical effects of the present invention in conjunction with the embodiments so as to fully understand the purpose, characteristics and effects of the present invention.

[0028] like Figure 1-4 As shown, a bag dust collector with uniform air intake includes a dust removal bin 1, a wind speed self-adjusting mechanism, a synchronous vibration cleaning mechanism, and an automatic discharging mechanism;

[0029] The dust collection bin 1 is cylindrical in shape, and an air outlet bin 2 is fixedly provided on the top plate of the dust collection bin 1, and a dust collecting bin 14 is fixedly provided on the bottom of the dust collection bin 1. The dust collecting bin 14 is conically arranged, and the dust collecting bin 14 is coaxially arranged with the dust collection bin 1. A mounting bracket 3 is fixedly provided on the outer wall of the dust collection bin 1, and reinforcing ribs 5 are fixedly provided between the side walls of adjacent mounting brackets 3. The mounting bracket 3 is arranged parallel to the axis of the dust collection bin 1, and the reinforcing ribs 5 are arranged perpendicular to the mounting bracket 3. A base 4 is fixedly provided on the bottom of the mounting bracket 3. The top pipeline of the right side wall of the dust collection bin 1 is connected to the air inlet pipe 6, and the pipeline of the left side wall of the air outlet bin 2 is connected to the air outlet pipe 7. The wind speed self-regulating mechanism is arranged inside the air inlet pipe 6, the synchronous vibration cleaning mechanism is arranged inside the air outlet bin 2, and the automatic discharging mechanism is arranged at the bottom of the dust collection bin 14. When in use, the wind speed self-adjusting mechanism can keep the air flow velocity flowing into the dust removal bin 1 stable and uniform, avoiding unstable dust removal effect caused by uneven wind speed. When the air flow flows, it drives the synchronous vibration cleaning mechanism to periodically clean the interior of the dust removal bin 1, avoiding the dust bag from being blocked and affecting the filtering effect. When the synchronous vibration cleaning mechanism is in operation, it drives the automatic discharging mechanism to automatically discharge the dust inside the dust collection bin 14, thereby realizing automatic discharging and reducing manpower waste.

[0030] The wind speed self-regulating mechanism includes a baffle 29, which is disposed inside the air inlet duct 6 and perpendicular to the axis of the air inlet duct 6. A first hydraulic rod 30 is connected to the side wall of the baffle 29 facing the dust collection bin 1. The first hydraulic rod 30 is perpendicular to the baffle 29. The other end of the first hydraulic rod 30 is fixedly connected to a mounting platform 32. A plurality of mounting rods 33 are fixedly disposed between the mounting platform 32 and the inner wall of the air inlet duct 6. The mounting rods 33 are perpendicular to the first hydraulic rod 30 and are evenly arranged on the outer side wall of the mounting platform 32. A first spring 31 is connected between the baffle 29 and the mounting platform 32 and is disposed around the outside of the first hydraulic rod 30. During use, air flows along the air inlet duct 6 into the dust collection bin 1. At this time, the baffle 29 is pushed toward the dust collection bin 1, causing the first hydraulic rod 30 to shorten and the first spring 31 to compress, generating an elastic force in the opposite direction on the baffle 29.

[0031] The inner wall of the air inlet duct 6 is rotatably connected to a plurality of movable baffles 34. These movable baffles 34 are evenly arranged along the axis of the air inlet duct 6 and are arranged in a fan-shaped manner. A second hydraulic rod 35 is rotatably connected to one side of the inner wall of the air inlet duct 6. The other end of the second hydraulic rod 35 is rotatably connected to the inner wall of the air inlet duct 6. When the second hydraulic rod 35 extends, it drives the movable baffles 34 to open, thereby reducing the flow area inside the air inlet duct 6. When the gas flow rate in the air inlet duct 6 increases, the thrust exerted on the baffle 29 increases, the movement amplitude of the first hydraulic rod 30 and the second hydraulic rod 35 increases, and the opening amplitude of the movable baffles 34 increases. Conversely, when the gas flow rate in the air inlet duct 6 decreases, the baffle 29 returns to its original position under the elastic force of the first spring 31, and the movable baffles 34 also return to their original position. This ensures that the gas flow rate inside the air inlet duct 6 remains stable and uniform, preventing uneven wind speed from causing unstable dust removal effect.

[0032] A first hydraulic chamber is defined within the end of the first hydraulic rod 30 away from the baffle 29 and is filled with hydraulic oil. A second hydraulic chamber is defined within the end of the second hydraulic rod 35 away from the movable baffle 34. The first and second hydraulic chambers are connected by a connecting pipe. When the first hydraulic rod 30 is shortened, the hydraulic oil within it is squeezed and flows along the connecting pipe into the second hydraulic rod 35, causing the second hydraulic rod 35 to extend.

[0033] The synchronous vibration cleaning mechanism includes an air inlet tube 17, which is vertically arranged on the inner wall of the dust removal bin 1 near the air inlet pipe 6. The input end of the air inlet tube 17 is connected to the air inlet pipe 6. An air duct 18 is arranged inside the air inlet tube 17. A rotating shaft 24 is arranged on the top plate of the air duct 18 so that it can rotate. A plurality of blades 25 are fixedly arranged at the bottom end of the rotating shaft 24. A partition 15 is fixed between the dust removal bin 1 and the air outlet bin 2. The top end of the rotating shaft 24 extends to the top of the partition 15. A first driving wheel 26 is arranged on the top end of the rotating shaft 24. After the air flow flows into the dust removal bin 1, it first flows into the interior of the air inlet tube 17. At this time, the blades 25 begin to rotate under the action of the wind, driving the rotating shaft 24 to start rotating. When the rotating shaft 24 rotates, it drives the first driving wheel 26 to start rotating.

[0034] The bottom of the partition 15 is fixedly provided with a plurality of connecting heads 16, the bottom of the connecting head 16 is provided with a dust removal bag 22, the bottom of the dust removal bag 22 is connected to a counterweight block 23, the outside of the side wall of the air outlet bin 2 facing the air inlet pipe 6 is fixedly provided with a connecting block 9, the outside of the connecting block 9 is fixedly provided with a high-pressure gas cylinder 8, the inner pipeline of the high-pressure gas cylinder 8 is connected to a diversion pipe 19, the inner end of the diversion pipe 19 extends to the interior of the air outlet bin 2, the bottom pipeline of the diversion pipe 19 is connected to a plurality of cleaning pipes 20, the bottom end pipeline of the cleaning pipe 20 is connected to a plurality of nozzles 21, the nozzles 21 are arranged at the top of the connecting head 16, and the number and position of the nozzles 21 match the connecting head 16. After the air flow flows out of the bottom of the air inlet tube 17, the larger dust particles inside it fall into the dust collecting bin 14, and the remaining gas is filtered by the dust removal bag 22 and passes through the connector 16 into the air outlet bin 2 and flows out along the air outlet pipe 7. During cleaning, the high-pressure gas inside the high-pressure gas cylinder 8 flows along the diversion pipe 19 into the cleaning pipe 20 and then is sprayed into the dust removal bag 22 at high speed along the nozzle 21. The dust removal bag 22 vibrates violently under the action of high pressure, thereby shaking off the dust on its surface into the dust collecting bin 14.

[0035] A first valve 36 is provided in the middle of the diverter pipe 19, and a stopper 38 is fixedly provided on the top of one side of the first valve 36 facing the air inlet pipe 6, and a movable switch 37 is movably provided on the other side of the top of the first valve 36, and a second spring 39 is connected between the movable switch 37 and the stopper 38. A connecting shaft 41 is provided on the top of the air outlet bin 2 away from the air inlet pipe 6, and a first driven wheel 42 is provided on the top of the connecting shaft 41. A transmission chain 40 is engaged between the first driven wheel 42 and the first driving wheel 26, and the diameter of the first driven wheel 42 is larger than the diameter of the first driving wheel 26. A cam 43 is connected to the bottom end of the connecting shaft 41, and the side wall of the cam 43 abuts against the movable switch 37. When the first driving wheel 26 rotates, the first driven wheel 42 is driven to rotate through the transmission chain 40 meshing with it, so that the connecting shaft 41 starts to rotate. When the connecting shaft 41 rotates, the cam 43 at the bottom is driven to rotate. When the cam 43 rotates, it periodically pushes the movable switch 37 to move in the direction of the block 38, so that the first valve 36 is periodically opened, thereby realizing periodic cleaning of the dust bag, effectively preventing the dust bag 22 from being clogged by dust and affecting the filtering effect.

[0036] The automatic discharge mechanism includes an upper slot 45, which is formed on the top of the air outlet bin 2 and is located on the top of the movable switch 37. A push rod 44 is fixedly provided on the top of the movable switch 37. The push rod 44 is arranged perpendicular to the top of the air outlet bin 2. The top end of the push rod 44 extends through the upper slot 45 to the top of the air outlet bin 2, and the push rod 44 is slidably connected to the upper slot 45. When the movable switch 37 moves, the push rod 44 at the top begins to move along the upper slot 45.

[0037] The input end of the air inlet pipe 6 is provided with a second valve 13. A lever switch 27 is rotatably provided at the top of the second valve 13. An upper connecting rod 28 is fixedly provided at the top of the lever switch 27. A cross bar is fixedly provided between the top end of the upper connecting rod 28 and the top rod 44. The cross bar is perpendicularly arranged to the upper connecting rod 28 and the top rod 44. A reinforcing rod is fixedly provided at the connection between the cross bar, the upper connecting rod 28 and the top rod 44. When the top rod 44 moves, the cross bar starts to move, causing the upper connecting rod 28 to start to move. When the upper connecting rod 28 moves, the lever switch 27 at the bottom rotates periodically, causing the second valve 13 to close during cleaning, preventing the inflow of air from affecting the cleaning effect of the high-pressure gas.

[0038] The bottom end of the dust collection bin 14 is provided with a discharge port 10, and a third valve 11 is provided at the bottom of the discharge port 10. A drive motor 12 is provided on the outer wall of the third valve 11. A trigger button 46 is provided on the side wall of the upper slot 45 facing the air inlet pipe 6. The trigger button 46 is electrically connected to the drive motor 12. When the push rod 44 moves to contact the trigger button 46, the drive motor 12 is activated, driving the third valve 11 to open, so that the discharge port 10 is conductive during cleaning, thereby achieving automatic discharge during cleaning, preventing excessive dust accumulation inside the dust collection bin 14, and eliminating the need for manual operation, thereby reducing manpower waste.

[0039] When the second hydraulic rod 35 is extended, the second hydraulic rod 35 is compressed, and the movable baffle 34 is opened when the second hydraulic rod 35 is extended, thereby reducing the flow area inside the air inlet pipe 6. When the air flow in the air inlet pipe 6 is greater, the thrust received by the baffle 29 is greater, the movement amplitude of the first hydraulic rod 30 and the second hydraulic rod 35 is greater, and the opening amplitude of the movable baffle 34 is greater. Conversely, when the air flow in the air inlet pipe 6 is smaller, the baffle 29 is reset under the elastic force of the first spring 31, and the movable baffle 34 is reset accordingly, thereby keeping the air flow inside the air inlet pipe 6 stable and uniform, and avoiding the unstable dust removal effect caused by uneven wind speed.

[0040] After the airflow flows into the dust collection bin 1, it first flows into the inside of the air inlet cylinder 17. At this time, the blades 25 begin to rotate under the action of the wind, driving the rotating shaft 24 to start rotating. When the rotating shaft 24 rotates, it drives the first driving wheel 26 to start rotating. After the airflow flows out of the bottom of the air inlet cylinder 17, the larger dust particles inside it fall into the inside of the dust collection bin 14. The remaining gas is filtered by the dust bag 22 and then passes through the connector 16 into the air outlet bin 2 and flows out along the air outlet pipe 7. During cleaning, the high-pressure gas inside the high-pressure gas cylinder 8 flows along the diverter pipe 19 into the cleaning pipe 20 and then is sprayed into the inside of the dust bag 22 at high speed along the nozzle 21. The dust bag 22 vibrates violently under the action of high pressure, thereby shaking off the dust on its surface into the interior of the dust collecting bin 14. When the first driving wheel 26 rotates, the first driven wheel 42 is driven to rotate through the transmission chain 40 meshing with it, so that the connecting shaft 41 starts to rotate. When the connecting shaft 41 rotates, the cam 43 at the bottom is driven to rotate. When the cam 43 rotates, it periodically pushes the movable switch 37 to move in the direction of the block 38, so that the first valve 36 is periodically opened, thereby realizing periodic cleaning of the dust bag, effectively preventing the dust bag 22 from being blocked by dust and affecting the filtering effect.

[0041] When the movable switch 37 moves, it drives the top push rod 44 to move along the upper slot 45. When the push rod 44 moves, it drives the cross bar to move, causing the upper connecting rod 28 to start moving. When the upper connecting rod 28 moves, it drives the bottom lever switch 27 to rotate periodically, so that the second valve 13 is closed during cleaning, preventing the inflowing airflow from affecting the cleaning effect of the high-pressure gas; when the push rod 44 moves to contact with the trigger button 46, the drive motor 12 is started, driving the third valve 11 to open, so that the discharge port 10 is connected during cleaning, thereby realizing automatic discharging during cleaning, avoiding excessive dust accumulation inside the dust collecting bin 14, and at the same time, no manual operation is required, reducing manpower waste.

[0042] The above embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work shall fall within the scope of protection of the present invention.
