Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cloth bag dust collector, in particular to a rotating blowing mechanism for pulse cloth bag dust collector. BACKGROUND

[0002] At present, the pulse cloth bag dust collector is one of the most widely used dust removal equipment in industrial flue gas purification and dust recycling, which mainly blows the filter bag by compressed air to make the dust attached to the surface of the filter bag fall off to restore the filtering performance. The existing cloth bag dust collector generally adopts a fixed pulse blowing mechanism, which is usually composed of an air pocket, a pulse valve, a blowing pipe and a nozzle. In the working process, the pulse valve releases compressed air at a fixed time, which is injected into the filter bag opening through the blowing pipe, thereby generating a transient reverse airflow for dust removal.

[0003] In the existing device, the dust removal effect of the blowing airflow mainly depends on the air pressure and the nozzle arrangement, and the distance between the jet end and the filter bag is a fixed structure, which cannot be dynamically adjusted according to the length of the filter bag or the thickness of the dust attachment, resulting in uneven dust removal intensity of the filter bag at different positions. Once the blowing distance deviates from the design value, it is easy to cause problems such as sufficient dust removal at the upper part and residual dust at the lower part, or excessive airflow impact causing damage to the filter bag. In addition, the air pocket and the blowing pipe are installed statically, and when the filter bags are arranged densely or in multiple rows, the nozzle switching needs to be controlled sequentially through multiple valve groups, which has a complex structure, a lagging response and a low dust removal efficiency.

[0004] For fine or sticky dust conditions, some equipment tries to add mechanical vibration dust removal or high-frequency electromagnetic oscillation structure based on airflow blowing, but mechanical impact can easily cause fatigue and wear of the filter bag, and the electromagnetic oscillation structure has problems such as high energy consumption, complex structure and difficult maintenance.

[0005] At present, there is still a lack of a rotating blowing mechanism that can simultaneously realize adjustable blowing angle, controllable blowing distance and airflow and sound wave coordinated dust removal function, so as to achieve coordinated optimization of intensity, range and energy saving in the cloth bag dust removal process.

[0006] Therefore, the existing problems are researched and improved, and a rotating blowing mechanism for pulse cloth bag dust collector is provided to solve the existing problems. SUMMARY

[0007] The present application aims to solve the technical problems in the prior art or related technology.

[0008] To this end, the technical solution adopted by the present application is as follows: a rotating blowing mechanism for pulse cloth bag dust collector, comprising a fixed frame, a rotating bearing assembly, an air pocket tank and a pulse assembly fixed to the bottom end of the air pocket tank.

[0009] The fixed frame is used for bearing and supporting the whole rotating structure, the rotating bearing assembly is responsible for realizing the rotation and lifting linkage of the gas pocket, the gas pocket is used for storing high-pressure gas and driving the pulse blowing process, and the pulse assembly includes a pulse blowing valve and an acoustic blower, which is used for realizing directional back blowing and acoustic auxiliary dust removal on the filter bag.

[0010] The device realizes the rotation and lifting compound motion of the gas pocket through synchronous and asynchronous driving of the motor, and completes the automatic dust removal process through the cooperation of pulse blowing and acoustic dust removal.

[0011] The fixed frame is fixedly installed at one end of the ring seat, the top surface of the ring seat is provided with a sliding guide sleeve, and the bottom surface is provided with a sleeve ring; the rotating bearing assembly is rotatably sleeved on the inner side of the sleeve ring, and a plurality of sliding rollers are rotatably installed on the surface of the sleeve ring and slide against the outer surface of the rotating bearing assembly; the gas pocket is slidably sleeved on the inner side of the sliding guide sleeve and the rotating bearing assembly, and the first driving motor and the second driving motor are installed on the fixed frame for power input. The rotating bearing assembly includes a ring seat, a first gear ring, a second gear ring and a bevel gear shaft; the two gear rings are provided with a conical ring tooth on the opposite surfaces, and the upper and lower tooth surfaces of the bevel gear shaft are engaged with the two gear rings for transmission. The output ends of the first and second driving motors are engaged with the two gear rings respectively, the rotation of the gas pocket is realized through synchronous driving, and the lifting of the gas pocket is realized through asynchronous driving. The outer surface of the gas pocket is provided with a sliding guide groove, and the inner surface is provided with a straight toothed rack which is engaged with the output tooth of the bevel gear shaft for transmission. The top of the gas pocket is provided with a gas filling port, and the bottom is fixed with a pulse assembly. This scheme realizes integrated driving of rotation and lifting, so that the blowing mechanism can flexibly adjust the jet angle and height, and improve the dust removal coverage and structural stability.

[0012] In a preferred example, the surface of the sliding guide sleeve is in the form of a ring sleeve structure, which is sleeved on the outer surface of the gas pocket for guiding the axial sliding and rotation of the gas pocket; the ring seat is slidably sleeved on the outer side of the gas pocket for stabilizing the lifting stroke of the gas pocket. This structure ensures the posture stability and good sealing performance of the gas pocket during lifting, avoids deviation and jamming, and improves the overall motion accuracy.

[0013] In a preferred example, a plurality of sliding rollers are arranged on the surface of the sleeve ring in the circumferential direction, each sliding roller slides against the outer circumferential surface of the ring seat for providing low-friction guidance during rotation. Through the circumferential support of the sliding rollers, the force distribution of the rotating bearing assembly is uniform when rotating, the friction loss is reduced, and the service life of the transmission components is prolonged.

[0014] In a preferred example, the ring seat, the first gear ring, the second gear ring and the sliding guide sleeve are coaxially arranged and consistent with the central axis of the gas pocket. This coaxial arrangement can ensure the rotation balance and accuracy of the blowing direction of the gas pocket, and avoid eccentricity causing jet deviation and structural vibration.

[0015] In a preferred example, the tapered ring teeth of the first and second tooth rings are respectively engaged with the upper and lower tooth surfaces of the bevel gear shaft, and the bevel gear shaft is provided with an output tooth at one end and is engaged with a straight rack in the sliding guide groove of the air bag tank. This structure realizes the conversion of rotary motion to linear lifting motion through gear engagement, so that the height adjustment of the air bag tank is accurately controllable, and different filter bag positions are adapted for dust removal.

[0016] In a preferred example, the first and second drive motors are both reduction motor structures, the input ends of which are connected to the control assembly, and the output ends of which are respectively engaged with the first and second tooth rings for transmission; the ends of the two motors are respectively provided with grating detection assemblies for real-time monitoring of the rotation speed and synchronization state. This scheme realizes closed-loop control of the motor output, ensures accurate matching of the rotation and lifting rhythm of the air bag tank, and improves the control accuracy of automatic dust removal.

[0017] In a preferred example, the pulse blowing valve includes a pulse electromagnetic valve, a gas guide cavity, a throttling hole pipeline, and a jet valve seat structure. The pulse electromagnetic valve is in communication with the air path of the air bag tank and is opened instantaneously under the action of a control signal, and compressed air is sprayed through the gas guide channel to form a strong back blowing airflow for pulse blowing of the filter bag. This structure releases a high-pressure airflow in a very short time, generates a transient pressure difference to remove dust from the surface of the filter bag, and ensures high blowing intensity and fast response.

[0018] In a preferred example, the acoustic blowing device includes a diaphragm driving unit, a pneumatic resonance cavity, and a resonance tube structure, which are in communication with the air path of the air bag tank. Compressed gas drives the diaphragm to vibrate to generate sound waves, which are amplified by the resonance cavity and output to the outer surface of the filter bag through the resonance tube at a working frequency of 75-350 Hz. This structure uses acoustic vibration to loosen residual dust during pulse intervals to prevent reattachment, forming a "air flow + acoustic energy" dual-effect dust removal mechanism to improve the thoroughness of dust removal and the service life of the filter bag.

[0019] The beneficial effects achieved by the present application are: 1. In the present application, the first and second tooth rings are driven by the first and second drive motors respectively for transmission, realizing synchronous rotation and asynchronous lifting of the rotation support assembly and the air bag tank, so that the pulse blowing assembly can blow and clean the filter bag in different heights and directions, effectively expanding the dust removal coverage and improving the overall dust removal efficiency.

[0020] 2. In the present application, the bevel gear shaft is engaged with the straight rack on the inner wall of the air bag tank to realize integrated control of the axial displacement and rotation of the air bag tank, while maintaining the sealing of the mechanism and the stability of the airflow, so that the blowing distance and angle can be dynamically adjusted to ensure the best matching of airflow impact force and filter bag force, thereby improving the uniformity of dust removal and the durability of the structure.

[0021] 3. In the present application, the integrated pulse blowing valve and the acoustic blowing device work together to complete the main dust removal under the action of high-pressure pulse airflow, and through the resonance of acoustic waves to assist in loosening fine dust, forming a double-effect dust removal mechanism of "airflow back blowing + acoustic oscillation", effectively preventing dust reattachment, reducing energy consumption and maintenance frequency, and realizing efficient, low-noise, long-period automatic dust removal operation.

DETAILED DESCRIPTION

[0024] To make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application is further described in detail below in combination with specific embodiments and with reference to the drawings. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0025] It is understood that the above description is only exemplary and is not intended to limit the scope of the present application.

[0026] Some embodiments of the application provide a rotating blowing mechanism for a pulse cloth bag dust collector.

[0027] In combination Figures 1-7 As shown in the drawings, the application provides a rotating blowing mechanism for a pulse cloth bag dust collector, which comprises a fixed frame 100, a rotating bearing assembly 200, a gas tank 300, and a pulse assembly 400 fixed to the bottom end of the gas tank 300.

[0028] The fixed frame 100 is the support base of the entire mechanism, one end of which is fixedly installed with a ring sleeve seat 110, the top surface of which is fixedly installed with a sliding guide sleeve 120 for providing guidance for the axial lifting and rotating movement of the gas tank 300. The bottom surface of the ring sleeve seat 110 is fixedly installed with a sleeve ring 130, which is annular in structure and has the rotating bearing assembly 200 sleeved on the inner side. A plurality of sliding rollers 131 are circumferentially and uniformly installed on the outer surface of the sleeve ring 130, which slide against the outer surface of the rotating bearing assembly 200 to reduce friction and guide the rotating movement.

[0029] The gas tank 300 is slidably sleeved on the inner side of the sliding guide sleeve 120 and the rotating bearing assembly 200 to realize the combined movement of rotation and lifting. The surface of the fixed frame 100 is fixedly installed with a first driving motor 140 and a second driving motor 150 for driving the rotating bearing assembly 200 to move.

[0030] The rotating bearing assembly 200 comprises a ring seat 210, the upper and lower surfaces of which are respectively rotatably installed with a first tooth ring 220 and a second tooth ring 230, and the opposite surfaces of the first tooth ring 220 and the second tooth ring 230 are respectively provided with a tapered ring tooth 221. A bevel gear shaft 240 is rotatably installed in the middle of the ring seat 210, and the upper and lower tooth surfaces of the bevel gear shaft 240 are respectively engaged with the tapered ring teeth 221 of the first tooth ring 220 and the second tooth ring 230.

[0031] The output ends of the first driving motor 140 and the second driving motor 150 are respectively engaged with the first tooth ring 220 and the second tooth ring 230 for transmission. When the two motors are synchronously driven, the ring seat 210 is driven to rotate as a whole via the first tooth ring 220 and the second tooth ring 230, realizing the axial rotation of the rotating bearing assembly 200, thereby driving the gas tank 300 and the pulse assembly 400 to perform circumferential blowing. When the two motors are asynchronously driven, an angular velocity difference is formed between the first tooth ring 220 and the second tooth ring 230, driving the bevel gear shaft 240 to rotate, and the output tooth 241 fixed at one end of the bevel gear shaft 240 is engaged with the straight toothed rack 311 on the inner side of the sliding guide groove 310 formed on the surface of the gas tank 300, realizing the lifting movement of the gas tank 300.

[0032] The top surface of the gas pocket tank 300 is provided with a filling port for connecting an external air pressure pump set to provide compressed air. The bottom end of the gas pocket tank 300 is fixedly provided with a pulse assembly 400, which includes a rotating plate 410, a pulse air blowing valve 411 and a sonic air blower 420. The pulse air blowing valve 411 is in communication with the gas path at the end of the gas pocket tank 300 and is used for pulse blowing and ash removal.

[0033] In this embodiment, the surface of the sliding guide sleeve 120 is in the form of a ring sleeve structure and is in sliding cooperation with the outer surface of the gas pocket tank 300, for guiding the axial lifting and circumferential rotation of the gas pocket tank 300. The ring seat 210 is slidingly sleeved on the outer side of the gas pocket tank 300, so that the gas pocket tank 300 can keep coaxial and uniform stress during lifting. Through the cooperation of the sliding guide sleeve 120 and the ring seat 210, the lifting and rotating movements of the gas pocket tank 300 are guided and constrained, so as to avoid eccentric vibration and air tightness instability.

[0034] In this embodiment, a plurality of sliding rollers 131 are uniformly arranged on the surface of the sleeve ring 130 in the circumferential direction, and the sliding rollers 131 are in sliding abutment with the outer periphery of the ring seat 210. This sliding guide relationship provides stable support when the rotating support assembly 200 rotates, avoids eccentric vibration and friction and wear, and thus ensures the axial rotation stability and durability of the rotating support assembly 200 as a whole.

[0035] In this embodiment, the ring seat 210, the first tooth ring 220, the second tooth ring 230 and the sliding guide sleeve 120 are coaxially arranged and coincide with the central axis of the gas pocket tank 300. Through this coaxial arrangement, the rotational inertia is uniformly distributed, the stress is balanced during rotation, and the structural deformation or air flow deviation caused by rotation deviation is effectively avoided, thereby improving the overall operation stability and blowing precision.

[0036] In this embodiment, the tapered ring teeth 221 on the surfaces of the first tooth ring 220 and the second tooth ring 230 are respectively engaged with the upper and lower surfaces of the bevel gear shaft 240, and the output teeth 241 at the other end of the bevel gear shaft 240 extend into the inner side of the sliding guide groove 310 on the surface of the gas pocket tank 300 and are engaged with the straight toothed bar 311 for transmission.

[0037] This engagement transmission mode enables the rotation of the bevel gear shaft 240 to be directly converted into the lifting movement of the gas pocket tank 300, realizes the combined linkage of rotation and linear displacement, and provides a structural basis for dynamic spacing adjustment of the pulse assembly 400.

[0038] In this embodiment, the first drive motor 140 and the second drive motor 150 are both in the form of a speed reduction motor structure, the input ends of which are electrically connected to a control assembly, and the output ends thereof are engaged with the first tooth ring 220 and the second tooth ring 230, respectively. The control assembly can realize synchronous or asynchronous driving mode switching of the two motors by setting instructions.

[0039] The grating detection assembly 141 installed at the output end of the motor is connected with the control assembly, and is used for monitoring the rotating speed, angle and running state of the two motors in real time, forming a closed loop feedback control, and ensuring the accurate matching of the rotating angle and the lifting displacement.

[0040] In this embodiment, the pulse blowing valve 411 comprises a pulse electromagnetic valve, a gas guide cavity, a throttle hole pipeline and a jet valve seat structure.

[0041] The pulse electromagnetic valve is in communication with the internal gas circuit of the gas tank 300, and is quickly opened when the control system sends a pulse signal, so that the compressed air is guided into the throttle hole pipeline through the gas guide cavity, and is sprayed at high speed through the jet valve seat structure, so that a strong airflow impact is generated on the filter bag opening, and a reverse airflow is formed to shake off the dust on the surface of the filter bag.

[0042] The pulse blowing valve 411 is connected with the gas guide channel in the rotating plate 410, and the airflow spraying direction is coaxially arranged with the axis of the cloth bag, so as to ensure that the blowing effect is uniform and the energy loss is minimum.

[0043] In this embodiment, the acoustic blowing device 420 is in communication with the gas circuit of the gas tank 300, and comprises a diaphragm driving unit, a pneumatic resonance cavity and a resonance pipe structure.

[0044] The diaphragm driving unit drives the diaphragm to vibrate periodically to generate sound waves by compressed gas; the pneumatic resonance cavity amplifies sound energy and maintains a stable resonance frequency; and the resonance pipe structure is arranged at the bottom of the rotating plate 410, and the sound waves are applied to the outer surface of the filter bag in the frequency band of 75-350 Hz.

[0045] The acoustic blowing device 420 and the pulse blowing valve 411 work cooperatively, and the adhered dust is loosened and detached by the vibration of the sound waves during the intermittent period of the airflow pulse, so as to reduce the reattachment of the dust and improve the overall dust removal efficiency.

[0046] The working principle and use process of the present application are as follows: The rotating blowing mechanism of the present application is in meshing transmission with the internal straight rack of the gas tank through the linkage of the double drive gear rings, so as to realize the rotating and lifting movement of the gas tank, and drive the pulse blowing and the acoustic dust removal function to work cooperatively.

[0047] When the equipment is running, the first driving motor 140 and the second driving motor 150 are started under the instruction of the control assembly: When the two motors are synchronously driven, the output torque is transmitted to the ring seat 210 through the first gear ring 220 and the second gear ring 230, so as to drive the rotating support assembly 200 to rotate around the central axis, so that the gas tank 300 and the pulse assembly 400 fixed at the lower end realize stable ring-shaped rotating blowing; When two motors are driven asynchronously, the angular velocity difference is formed between the gear rings, the bevel gear shaft 240 rotates, and the output gear 241 at the end of the bevel gear shaft 240 is engaged with the straight rack 311 on the inner wall of the air bag tank 300, so as to realize the axial lifting adjustment of the air bag tank, the distance between the pulse assembly 400 and the surface of the cloth bag is reasonably controlled, and the pulse assembly 400 is driven to rotate to alternately clean the dust in different areas of the cloth bag.

[0048] After the air bag tank 300 is filled with high-pressure air by the external air pressure pump group, under the action of the timing pulse signal of the control system, the pulse blowing valve 411 is instantaneously opened, the compressed air is quickly released along the internal air guide channel of the rotating plate 410, and a pulse air flow jet is formed. The airflow is aligned with the filter bag port through the nozzle to produce strong back blowing, so that the instantaneous pressure difference inside and outside the filter bag changes sharply, thereby shaking off the attached dust.

[0049] During the intermittent period of pulse blowing, the acoustic blowing device 420 works by utilizing the diaphragm vibration and the resonance cavity structure, and outputs a sound wave energy field with a frequency of 75-350 Hz to act on the surface of the filter bag, so as to loosen and detach the fine dust and prevent the dust from re-attaching. The synergistic effect of pulse blowing and acoustic dust cleaning realizes a high-efficiency, stable and low-energy-consumption automatic dust cleaning process.

In the present specification, the illustrative description of the above terms does not necessarily refer to the same embodiment or example.
