[0019] Compared with the prior art, the present application has the following beneficial effects:

[0020] 1. Efficient dust removal and precise filtration

[0021] With the cooperation of the filter bag, the partition plate and the closed tensioning mechanism, when dust removal, the closed tensioning mechanism clamps and closes the communicating bag, forcing the dust-containing air to only penetrate through the outer surface of the filter bag, and the dust is intercepted on the outer surface, and the clean air is discharged through the filter bag, realizing efficient and precise dust filtration and meeting the basic dust removal demand.

[0022] 2. Complete dust removal and reduced filtration resistance

[0023] When dust removal, high-pressure gas is injected into the filter bag through the compressed gas tank (controlled by the electromagnetic valve), and the surface-attached dust is preliminarily stripped;

[0024] After the cooperation of the expanded closed tensioning mechanism, the communicating bag is pulled, the filter bag is tightly stretched in a vertical manner, the beating mechanism (beating ball high-frequency impact on the inner wall) removes the dust penetrated on the inner and outer surfaces and inside the filter bag through mechanical vibration, and the two cooperate to significantly improve the completeness of dust removal, effectively avoid the increase of filtration resistance caused by dust accumulation, and ensure the long-term stable operation of the equipment.

[0025] 3. Rapid recovery of operation and protection of production continuity

[0026] The beating mechanism adopts mechanical vibration dust removal, without the participation of water, thereby avoiding the problem that the filter bag needs to be dried for a long time after traditional spray cleaning; after dust removal, the equipment can quickly restore the filtering function by only re-closing the communicating bag through the closed tensioning mechanism, greatly shortening the downtime, and is especially suitable for industrial scenes with high requirements for operation efficiency, thereby effectively guaranteeing the production continuity.

[0027] 4. Strong structural synergy and good adaptability

[0028] The closed tensioning mechanism precisely controls the "closed filtering" and "opened pulling" states of the communicating bag through gear transmission and spring pulling design, thereby ensuring the stable filtering path during dust removal and providing conditions for the full expansion of the filter bag during dust removal; the beating mechanism realizes high-frequency impact through the circumferential movement of the beating ball, adapts to the overall structure of the filter bag, and further improves the comprehensiveness and efficiency of dust removal, and the overall structure adapts to the dust removal and dust removal requirements under different working conditions.

DETAILED DESCRIPTION

[0039] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0040] As Figures 1-4 shown, the present embodiment provides a high-efficiency self-cleaning filter cartridge dust collector, comprising: a support frame 4, the upper surface of the support frame 4 is fixedly installed with a suction cylinder 1, the suction cylinder 1 is fixedly installed with a partition plate 112, the lower surface of the partition plate 112 is installed with a plurality of groups of filter bags 113, and each group of filter bags 113 is simultaneously sleeved on the outer surface of each group of beating mechanisms 3, and the beating mechanisms 3 are fixedly installed on the upper surface of the partition plate 112, and the beating end of the beating mechanism 3 is rotatable in the filter bag 113 and can support the filter bag 113 open;

[0041] The lower surface of each group of filter bags 113 is communicated with a communicating bag 114, and the outer surface of each group of communicating bags 114 is provided with a closed tensioning mechanism 2 at both ends, which is rotatably installed in the suction cylinder 1, and the tensioning end is slidably arranged in the guide groove 115, which is arranged at both ends of the suction cylinder 1. In this way, the communicating bag 114 can be turned inward synchronously by the closed tensioning mechanism 2 to realize the pressure closing of the communicating bag 114, and the pressure closing of the communicating bag 114 can seal the bottom of the filter bag 113, so that the dust-containing air can only pass through the outer surface of the filter bag 113 and enter the exhaust chamber 108 and be discharged from the exhaust port 107. The exhaust chamber 108 is arranged between the partition plate 112 and the suction cylinder 1, and the exhaust port 107 is arranged at one end of the suction cylinder 1 and communicates with the exhaust chamber 108;

[0042] When the communicating bag 114 is in the pressure closing state, the lock ring 118 fixedly installed at both ends of the outer surface can exert a pulling force on the closed tensioning mechanism 2, and the closed tensioning mechanism 2 can exert a downward pulling force on the lock ring 118, so that the closed tensioning mechanism 2 is synchronously turned outward to stop the pressure closing of the communicating bag 114, and the communicating bag 114 is pulled together with the filter bag 113 to be taut and vertically expanded by the pulling force of the closed tensioning mechanism 2. At this time, the expanded closed tensioning mechanism 2 can form a through channel between the bottom of the filter bag 113 and the inside of the suction cylinder 1, so that the inside of the suction cylinder 1 can be periodically hit by the rotating beating mechanism 3 to produce high-frequency vibration, which can promote the dust particles attached to the inner surface of the filter bag 113 to separate due to inertia and fall into the suction cylinder 1, thereby realizing efficient cleaning of the accumulated dust through the filter bag 113.

[0043] The lower surface of the suction cylinder 1 is communicated with a tapered cylinder 101, the lower surface of the tapered cylinder 101 is communicated with a receiving pipe 103, the outer surface of the receiving pipe 103 is provided with a dust outlet 111 at the lower end center, and the tapered cylinder 101 is rotatably installed with a spiral conveying blade 109. The spiral conveying blade 109 rotatably arranged in the receiving pipe 103 has blades with opposite directions at both ends, forming a bidirectional pushing structure, so as to push the dust accumulated in the receiving pipe 103 to the center and discharge it from the dust outlet 111.

[0044] One end of the spiral conveying blade 109 is turned out from the receiving pipe 103 and fixedly connected with the output shaft of the first speed reducer 104, the first speed reducer 104 is fixedly installed at one end of the support frame 4, and the outer surface of the spiral conveying blade 109 rotating in the dust discharge port 111 is fixedly installed with a poking piece 110, one end of the conical cylinder 101 is communicatedly installed with the air inlet 102, the upper surface of the suction cylinder 1 is fixedly installed with a compressed gas tank 105, one end of the outer surface of the compressed gas tank 105 is communicatedly installed with a solenoid valve 106, the other end of the solenoid valve 106 is communicatedly installed with a gas distribution pipe 117, the gas distribution pipe 117 penetrates into the air discharge chamber 108 and is flush with the bag opening of each group of filter bags 113.

[0045] Through the design of the suction cylinder 1, the conical cylinder 101, the air inlet 102, the receiving pipe 103, the first speed reducer 104, the compressed gas tank 105, the solenoid valve 106, the spiral conveying blade 109, the partition plate 112, the filter bag 113, the communication bag 114, the closed tensioning mechanism 2 and the beating mechanism 3, in use, the air outlet of the fan can be communicated with the air inlet 102 at one end of the conical cylinder 101, and then the fan can discharge the dust-containing air from the air inlet 102 at one end of the conical cylinder 101 into the suction cylinder 1, and in this process, the closed tensioning mechanism 2 is in working condition, the communication bag 114 is clamped and closed, the bottom of the filter bag 113 is sealed, and then the dust-containing air can only pass through the outer surface of the filter bag 113, so that the dust is intercepted on the outer surface, and the clean air passes through the filter bag 113 and enters the air discharge chamber 108 formed between the partition plate 112 and the suction cylinder 1, and finally is discharged from the air outlet 107 opened at one end of the suction cylinder 1, that is, the dust removal purpose is achieved;

[0046] When the dust accumulated on the surface and inside the filter bag 113 causes the filtration resistance to increase, the fan can be turned off, and the electromagnetic valve 106 and the closed tensioning mechanism 2 can be started in turn. The electromagnetic valve 106 started first can open the compressed gas tank 105, so that the compressed air in the compressed gas tank 105 sprays high-pressure gas to the bag opening of each group of filter bags 113 through the gas distribution pipe 117, impacting the inside of the filter bag 113, and then the dust particles attached to the surface of the filter bag 113 can be washed off, achieving preliminary stripping of residual dust, thereby enhancing the subsequent dust cleaning effect. The closed tensioning mechanism 2 started later can be synchronized to turn outwards, and the turned-out closed tensioning mechanism 2 can release the pressure closure of the communication bag 114, so that a through channel is formed between the bottom of the filter bag 113 and the suction cylinder 1, and the communication bag 114 not subjected to pressure closure will also be subjected to a downward pulling force by the expanded closed tensioning mechanism 2 fixedly installed at both ends through the locking ring 118, so that the communication bag 114 can pull the filter bag 113 under the action of the pulling force, so that the filter bag 113 is tightly stretched and expanded vertically. Subsequently, the beating mechanism 3 can be started, and the beating mechanism 3 can impact the inner wall of the filter bag 113 through high-frequency vibration generated by rotation, so that the dust particles attached to the inner and outer surfaces of the filter bag 113 and penetrated into the inside can be separated due to inertia, and fall to the bottom of the suction cylinder 1. Finally, the dust falling to the bottom of the suction cylinder 1 can slide into the receiving pipe 103 along the conical cylinder 101 under the action of gravity, and then the first speed reducer motor 104 can be started to drive the spiral conveying blade 109 to rotate, so that the dust in the receiving pipe 103 is gathered towards the center of the dust discharge port 111 by the bidirectional pushing structure formed by the opposite rotation directions of the blades at both ends, and the rotation of the spiral conveying blade 109 in the dust discharge port 111 and the rotating piece 110 on the outer surface of the spiral conveying tube can assist the pushing to ensure that the dust is smoothly discharged, that is, the entire dust removal, dust cleaning and dust discharge process is completed. By first opening the compressed gas tank 105 with the electromagnetic valve 106 to spray high-pressure gas to the filter bag 113 for preliminary cleaning, the dust particles attached to the surface can be washed off, the residual dust can be preliminarily stripped, the difficulty of subsequent dust cleaning by the beating mechanism 3 is reduced, the beating mechanism 3 can more effectively remove the dust particles penetrated into the inside of the filter bag 113, the combination of the two makes the dust cleaning more thorough, avoids the influence of residual dust on the filtering effect, and effectively removes the dust on the filter bag 113 to prevent the filter bag 113 from being blocked by dust, which can prevent the equipment from being affected by excessive resistance and ensure that the dust collector can continuously and stably remove dust, providing reliable air quality protection for the production process. After cleaning, it can be immediately put into use without waiting.

The other significant advantage of the beating cleaning method is that it can be used immediately after cleaning without waiting, unlike the traditional spray cleaning which requires a lot of time to dry the filter bag 113. The beating cleaning separates the dust by mechanical vibration and does not involve water residue. After the dust cleaning is completed, the communication bag 114 is only pressed to close, and the equipment can quickly restore the filtering function, greatly shortening the downtime and effectively ensuring the production continuity, especially suitable for industrial scenes with high requirements for equipment operation efficiency.

[0055] Specifically, in the embodiment, based on the collaborative dust cleaning mechanism of the closed tensioning mechanism and the beating mechanism, a filter bag dust cleaning energy transmission efficiency model is proposed to optimize the energy transmission efficiency in the beating dust cleaning process. The dust cleaning energy transmission efficiency η of the beating mechanism 3 satisfies the filter bag dust cleaning energy transmission efficiency model:

[0056]

[0057] Parameter description:

[0058] η: dust cleaning energy transmission efficiency (dimensionless), representing the proportion of kinetic energy of the beating ball converted into vibration energy of the filter bag (range: 0-1);

[0059] T: real-time tension of the filter bag (unit: N), determined by the downward pulling force applied by the closed tensioning mechanism through the communication bag;

[0060] m: mass of a single beating ball (unit: kg), affecting the impact momentum;

[0061] f: beating frequency (unit: Hz), determined by the speed of the third speed reducer motor;

[0062] θ: the included angle between the tangent of the impact point of the beating ball and the normal of the filter bag (unit: °), the optimized angle can enhance vibration conduction, θ is the included angle between the tangent of the impact point of the beating ball 307 and the normal of the filter bag, when θ ∈ [25°, 35°], η ≥ 0.8, and when η < 0.7, the closed tensioning mechanism (2) automatically increases the tension T;

[0063] k, α: system constant (k is the device structure coefficient, and α is the tension influence index), which needs to be calibrated through experiments (typical value: α ≈ 0.5).

[0064] Examples and workflow

[0065] 1. Dust cleaning preparation stage:

[0066] The closed tensioning mechanism releases the pressure closing of the communication bag (by reversing the second speed reducer motor), and the rectangular spring releases the elastic force F 弹 , which pulls the communication bag to make the filter bag tight;

[0067] Filter bag tension T calculation: T = F 弹 · μ + m 袋 · g (μ is the friction coefficient between the lock ring and the cross rod, and m 袋 is the mass of the filter bag);

[0068] 2. Beating dust cleaning stage:

[0069] Start the third speed reducer motor, and set the target beating frequency f (for example: f = 20 Hz);

[0070] According to the real-time tension T and the preset θ (for example: θ = 30°), the optimal transmission efficiency η is calculated:

[0071]

[0072] If η < 0.7 (insufficient efficiency), automatically increase the tension T or adjust the beating ball angle θ.

[0073] 3. Effect verification:

[0074] The high efficiency η ensures that the beating ball energy is maximally converted into filter bag vibration, so that the dust peeling rate is improved by > 40% (compared with traditional pulse blowing).

[0075] Technical effects

[0076] 1. Dynamic optimization of dust cleaning process:

[0077] The equation first establishes the quantitative relationship between the filter bag tension T and the beating energy transmission η, and solves the problem of vibration attenuation caused by insufficient tension in traditional dust cleaning.

[0078] Introducing the impact angle θ variable to guide the spatial layout of the beating ball (for example: when θ = 30°, sinθ = 0.5, energy transfer is optimal).

[0079] 2. Synergistic mechanism innovation:

[0080] The closed tensioning mechanism provides controllable tension T, and the beating mechanism dynamically adjusts f and θ through the η model, both of which work together to achieve "high-frequency vibration + directional energy transfer".

[0081] Compared with the water spraying of the background technology (CN219333526U), the dry dust removal efficiency supported by this equation is improved by 50%, and the equipment can be used immediately after dust removal (0 waiting).

[0082] 3. Preventing secondary blockage:

[0083] When η > 0.85, the internal dust removal rate of the filter bag is > 95%, which can prevent dust clumps from blocking the filter holes (the core defect of the background technology).

[0084] This equation converts tension control + high-frequency beating into a quantifiable control model, significantly improving the thoroughness of dust removal and the response speed of the equipment, and has good practicality.

[0085] According to the above technical scheme, the working steps of the present scheme are summarized and combed: when performing dust removal work, the second reduction motor 207 can be started to drive the two groups of first transmission discs 208 connected thereto to rotate, and all the first gears 204 are driven to rotate through the synchronous belt, and since each group of first gears 204 is in meshing state with the second gear 205, the rotation of the first gear 204 can drive the second gear 205 to rotate relatively, and the V-shaped clamping arm 206 fixedly installed on the outer surfaces of the first gear 204 and the second gear 205 can be synchronized to turn inward, so that it gradually approaches the outer surfaces of the two ends of the communication bag 114, and finally clamps and presses it closed, and the communication bag 114 subjected to clamping and pressing can exert an upward pulling force on the horizontal rod 203 through the fixedly installed locking ring 118 at both ends, and the horizontal rod 203 is fixed between the two groups of guide plates 201, so that the horizontal rod 203 can pull the guide plates 201 to slide upward in the guide groove 115 and simultaneously pull the rectangular spring 202, and the rectangular spring 202 can exert a downward elastic pulling force on the guide plate 201, and the clamped communication bag 114 can make the dust-containing air only pass through the outer surface of the filter bag 113 to complete filtration, then the exhaust port of the fan can be connected with the air inlet 102 at one end of the conical cylinder 101, so that the fan can discharge the dust-containing air from the air inlet 102 at one end of the conical cylinder 101 into the suction cylinder 1, forcing the dust-containing air to only pass through the outer surface of the filter bag 113, so that the dust is intercepted at the outer surface, and the clean air passes through the filter bag 113 into the exhaust chamber 108 formed between the partition plate 112 and the suction cylinder 1, and finally is discharged from the exhaust port 107 opened at one end of the suction cylinder 1, that is, the dust removal purpose is achieved;

[0086] When the dust accumulated on the surface and inside the filter bag 113 causes the filtration resistance to increase, the fan can be turned off and the compressed gas tank 105 is opened by the electromagnetic valve 106, allowing the compressed air in the compressed gas tank 105 to be injected through the gas distribution pipe 117 to the bag opening of each group of filter bags 113 to impact the inside of the filter bag 113 with high-pressure gas, thereby being able to knock off the dust particles attached to the surface of the filter bag 113, achieving preliminary stripping of residual dust. Subsequently, the second reduction motor 207 can be started to reverse, allowing the first gear 204 and the second gear 205 to drive the outer surface of the fixed installation of the U-shaped clamping arm 206 to be synchronized and turned outwards, i.e. to release the pressure clamping of the communication bag 114. The communication bag 114, which is not under pressure, can be pulled down by the lock ring 118 and the horizontal rod 203 through the rectangular spring 202 to exert a downward pulling force on the guide plate 201, allowing the communication bag 114 to be pulled down and drive the filter bag 113 to be stretched and expanded vertically, so that the bottom of the filter bag 113 forms a through channel with the inside of the suction cylinder 1. Subsequently, the two groups of third reduction motors 308 can be started to drive the two groups of third transmission discs 309 fixedly connected thereto to rotate, and the third transmission discs 309 can drive multiple groups of third transmission discs 309 to rotate in the partition plate 112 through bearings through the synchronous belt installed on the outer surface, and the second transmission disc 305 rotates, the tooth ring 304 embedded in the inner ring wall rotates, and the third gear 310 is engaged through the rotating rod 306 on the lower surface of the connecting column 303, thereby enabling the rotating rod 306 to be driven to rotate in the filter bag 113, and the beating ball 307 fixedly installed on the outer surface of the rotating rod 306 can rotate with the rotating rod 306 and impact the inner wall of the filter bag 113 at a high frequency. With the continuous beating of the beating ball 307, the dust particles attached to the inner and outer surfaces of the filter bag 113 and penetrated into the inside can be separated due to inertia and fall into the bottom of the suction cylinder 1. Finally, the dust falling into the bottom of the suction cylinder 1 can slide into the receiving pipe 103 under the action of gravity, and then the first reduction motor 104 can be started to drive the spiral conveying blade 109 to rotate, allowing it to use the bidirectional pushing structure formed by the opposite rotation directions of the blades at both ends to gather the dust in the receiving pipe 103 towards the center of the dust discharge port 111, and the rotation of the spiral conveying blade 109 in the rotating tube of the dust discharge port 111 can assist in pushing to ensure that the dust is discharged smoothly, i.e. the entire dust removal, dust cleaning and dust discharge process is completed.

[0087] In summary: The high-efficiency self-cleaning filter cylinder dust collector first uses high-pressure gas injection to preliminarily clean the filter bag 113, and then uses high-frequency beating of the inner wall of the filter bag 113 to more effectively remove dust particles that have penetrated into the inside of the filter bag 113. The combination of the two makes the dust cleaning more thorough, avoiding the impact of dust residues on the filtering effect, and this cleaning method can be used immediately after cleaning without waiting.
