Description

Technical Field

[0001] This invention belongs to the field of industrial environmental management equipment technology, and in particular relates to an automatic dust removal device for dust removal pipelines. Background Technology

[0002] In industrial production processes, dedicated environmental dust collection systems are needed to prevent industrial dust pollution. Common environmental dust collection systems include dust collection ducts. During dust collection, maintaining a set airflow velocity within the ducts ensures the smooth transport of industrial dust to the collection equipment, preventing dust accumulation within the ducts. However, in practical applications, various unforeseen circumstances can cause the airflow velocity within the dust collection ducts to consistently fall below the set value. This leads to frequent dust accumulation at locations where pipe diameter or shape changes, such as elbows and reducers. Increased dust accumulation severely impacts the normal operation of the dust collection system. Secondly, for large-scale dust collection systems, such as those in steel metallurgical plants, the duct diameter can reach 3 to 6 meters, and the dust accumulation can reach tens or even hundreds of tons. Furthermore, because environmental dust collection systems often employ high-altitude dust collection structures, the dust collection ducts are also erected high above the plant area. Under such immense pressure, the dust collection ducts can collapse without warning, resulting in personal injury and property damage.

[0003] To address the problem of dust accumulation in dust collection pipelines, manual dust removal is typically used for larger diameter pipelines. These pipelines are equipped with manholes for cleaning accumulated dust and compressed air purging pipes to manually blow away the deposited industrial dust. However, manual dust removal has significant limitations, primarily: it requires the dust collection system to be shut down, rendering normal dust collection impossible; the manual operation of compressed air purging causes severe pollution, and because the dust collection system is shut down, the cleaned dust will re-settle after being dispersed; the cleaning process generates significant industrial dust pollution, with large amounts of dust-laden gas leaking into the environment, causing air pollution and harm to human health.

[0004] Therefore, there is an urgent need for a device that can automatically clean dust from large-diameter dust collection pipes to prevent excessive dust accumulation from causing safety accidents and to avoid the various drawbacks of manual dust cleaning.

[0022] The raw materials and instruments used in the examples are not subject to any specific restrictions on their source; they can be purchased from the market or prepared according to conventional methods known to those skilled in the art.

[0023] Please refer to the following: Figures 1-3 The contents are shown to better understand the specific structure of the present invention. An automatic dust removal device for a dust collection pipe 4 according to a preferred embodiment of the present invention is shown below. Figure 1 As shown, it includes: a gas source 1 and a gas storage unit 2. Specifically, the gas source 1 is connected to the gas storage unit 2 through a pipeline and supplies gas to the gas storage unit 2. The gas storage unit 2 stores the gas supplied by the gas source 1 and compresses it inside itself to form high-pressure gas.

[0024] Specifically, the air source 1 can adopt, but is not limited to, an air compressor structure. The air storage unit 2 can adopt, but is not limited to, an air storage cylinder structure.

[0025] In this embodiment, a dust removal unit 3 is also included. This unit can be an air passage structure, with one end of the air passage connected to or disconnected from the air storage unit 2. It is used to deliver the high-pressure gas in the air storage unit 2 to the dust removal pipe 4 by jetting.

[0026] In this embodiment, a jetting control component 5 is also included, which can be disposed between the gas storage section 2 and the dust removal unit 3, and is used to control the connection and disconnection between the gas storage section 2 and the dust removal unit 3.

[0027] This embodiment also includes a power supply unit 6, which can be powered by connecting to an industrial power supply or by a battery. The specific structure of the power supply unit 6 is not limited in this invention. The power supply unit 6 is electrically connected to the jet control component 5 and is used to supply power to the jet control component 5.

[0028] In practical implementation, the automatic dust removal device for dust collection pipeline 4 provided by this invention is suitable for dust removal work on large-diameter dust collection pipeline 4. Multiple sets can be arranged along the dust collection pipeline 4, especially at locations where the dust collection pipeline 4 undergoes structural changes, such as bends and diameter changes. The automatic dust removal device for dust collection pipeline 4 provided by this invention can effectively solve the problems of safety accidents caused by excessive dust accumulation in large-diameter dust collection pipeline 4, as well as the poor effectiveness, environmental pollution, and health hazards associated with manual dust removal.

[0029] In some embodiments, such as Figure 1 As shown, one end of the air passage of the dust removal unit 3 is connected to the air storage unit 2 via the jet blowing control component 5. Specifically, the jet blowing control component 5 can connect or disconnect the air storage unit 2 and the dust removal unit 3. The other end extends into the dust removal pipe 4 and can be arranged at the bottom of the pipe for easy upward jetting of dust.

[0030] In this embodiment, the dust removal unit 3 is provided with a gas jet hole 301 at one end inside the dust removal pipe 4. Specifically, there can be multiple gas jet holes 301, which can be opened above, to the left and to the right of the air passage of the dust removal unit 3, so that gas can be sprayed into the dust from all directions to increase the amount of dust disturbance.

[0031] In some embodiments, such as Figure 1 As shown, the automatic dust removal device also includes, but is not limited to, the pilot line 7, and the pilot air pressure control unit 8, the pilot air path control unit 9 and the one-way flow unit 10 arranged sequentially on the pilot line 7 according to the air path direction.

[0032] Specifically, the pilot pipeline 7 can be a section of gas path, with one end connected to the gas storage section 2 and the other end connected to the pipeline of the dust removal unit 3 located outside the dust removal pipe 4.

[0033] In this embodiment, the pilot gas pressure control unit 8 is installed on the pilot line 7 and is used to control the gas pressure in the pilot line 7.

[0034] Specifically, the pilot air pressure control unit 8 can employ a pressure reducing valve structure, such as a diaphragm-type pressure reducing valve, piston-type pressure reducing valve, or bellows-type pressure reducing valve as used in existing technologies. This reduces the air pressure entering the pilot line 7 from the air storage unit 2, creating a lower pressure environment within the pilot line 7. Furthermore, an adjustable pressure reducing valve can be used, allowing the pressure value to be set according to actual conditions to achieve the desired pressure reduction effect. By adjusting the pressure value of the pressure reducing valve, different pressures can be created in the pilot line 7 to accommodate different dust accumulation levels and cleaning needs.

[0035] In this embodiment, the pilot air path control unit 9 can adopt a solenoid valve 501 structure, such as the slide valve or seat valve solenoid valve 501 in the prior art. The pilot air path control unit 9 can be electrically connected to the control unit 12 of the dust removal pipeline 4, or a separate control unit 12 can be set in this automatic dust removal device. However, considering cost saving and structural optimization, it is preferable to adopt the form of sharing the control unit 12 with the dust removal pipeline 4.

[0036] Specifically, the control unit 12 of the dust removal duct 4 can adopt existing technologies, such as PLC (PLC is the abbreviation for Programmable Logic Controller), or it can be a circuit including at least one processor, or a circuit including at least one microcontroller, or it can be a combination of multiple circuits or chips, as long as it can achieve the corresponding function; it is understood that for those skilled in the art, the control circuit can also be a common circuit composed of amplifiers, comparators, transistors, MOSFETs, etc., to achieve the corresponding function in a purely hardware manner.

[0037] Specifically, the pilot gas path control unit 9 can automatically open or close the pilot gas path 7 under the action of the control unit 12. It can be automatically controlled by a timed opening and closing method, and the specific time interval can be set according to the specific situation.

[0038] In this embodiment, the one-way flow section 10 can adopt a one-way valve structure.

[0039] Specifically, the one-way flow section 10 can restrict the gas to flow in only one direction, while preventing it from flowing in the opposite direction. Its function is to form a one-way gas flow path from the gas storage section 2 to the dust removal pipe 4 between the pilot pipe 7 and the gas path of the dust removal unit 3.

[0040] Specifically, a pilot control system is formed by configuring a pilot air path 7, a pilot air pressure control unit 8, a pilot air path control unit 9, and a one-way flow section 10, which connects the air storage unit 2, the dust removal unit 3, and the dust removal pipe 4. This system can periodically open the pilot air path to detect the amount of dust accumulation in the dust removal pipe 4 using a low-pressure method. If the amount of dust is small, the air pressure in the pilot air path 7 is low because the gas jet 301 of the dust removal unit 3 is not blocked. If the amount of dust is large, the gas jet 301 is blocked, resulting in a higher air pressure in the pilot air path 7. This pressure variation in the pilot air path 7 generates a control signal, which in turn controls the dust removal action of the automatic dust removal device.

[0041] In practical implementation, this control method shares the control unit 12 with the dust removal duct 4, saving costs and optimizing the structure. It also allows for periodic detection of dust accumulation in the dust removal duct 4 using a small amount of low-pressure gas, reducing the consumption of the pressurized air source 1 and lowering the operating cost of the automatic dust removal device. The automatic dust removal device can automatically identify the amount of dust accumulation based on changes in the air pressure within the pilot line 7 and proactively start and stop the dust removal operation. This avoids various problems caused by excessive dust accumulation in the dust removal duct 4 and prevents resource waste caused by activating the automatic dust removal device when dust accumulation is low.

[0042] In some embodiments, such as Figure 1 As shown, the automatic dust removal device also includes a pilot pneumatic unit 11, which is located at one end of the pilot pipeline 7.

[0043] Specifically, the pilot pneumatic unit 11 can be disposed at the end of the branch of the pilot air path 7 between the pilot air path control unit 9 and the one-way flow section 10, and is electrically connected to the jet control component 5 and the power supply unit 6 respectively, forming a circuit loop of the jet control component 5, the power supply unit 6 and the pilot pneumatic unit 11.

[0044] Specifically, the pilot pneumatic unit 11 can adopt a pneumatic switch structure from existing technology. The principle is that an elastic diaphragm is internally formed in the pilot pneumatic unit 11. One side of the diaphragm is connected to the air path, and the other side has a contact point connected to the circuit. When the pressure in the air path reaches a set value, it pushes the diaphragm towards the contact point, connecting the circuit; when the pressure does not reach the set value, the diaphragm, under its elastic force, drives the contact point back to its original position towards the air path, thus disconnecting the circuit.

[0045] In practice, the pilot pneumatic unit 11 can convert the changes in air pressure in the pilot circuit 7 into a switching signal, thereby controlling the on / off state of the blow-off control component 5, the power supply unit 6 and the pilot pneumatic unit 11 circuit, providing a favorable guarantee for the automatic dust removal device to realize the automatic dust removal function.

[0046] In some embodiments, such as Figure 2As shown, the jet control component 5 can adopt the electromagnetic pulse valve structure in the prior art, including but not limited to the electric part and the pneumatic part.

[0047] Specifically, the electric control unit can adopt a structure of solenoid valve 501 plus control diaphragm 502, powered by power supply unit 6, and can be used to control the connection and disconnection of the pneumatic control unit.

[0048] Specifically, the air control unit can adopt a structure of spring 503 and blowing diaphragm 504, which are connected to the air storage unit 2 and the dust removal unit 3 respectively. The air passage between the air storage unit 2 and the dust removal unit 3 can be connected or disconnected through the action of the blowing diaphragm 504.

[0049] Specifically, the jet-blowing control component 5 can "instantly transform" the compressed air inside the air storage section 2 into a strong airflow, and transmit it to the dust removal pipe 4 through the dust removal unit 3 to achieve high-speed jet-blowing of accumulated dust. Its working principle is as follows: When the jet-blowing control component 5 is not powered on, the compressed gas in the air storage section 2 enters the upper end of the jet-blowing diaphragm 504 through the small hole 505 provided in the air control unit, pressing the jet-blowing diaphragm 504 against the upper edge of the air outlet 507, disconnecting the connection between the air inlet 506 (connected to the air storage section 2) and the air outlet 507. The upper end of the jet-blowing diaphragm 504 is also connected to the lower end of the control diaphragm 502 through the air passage 508. At this time, because it is not powered on, the control diaphragm 502 is pressed against the upper end of the exhaust port 510 under the action of the solenoid valve spring 509. When the jet-blowing control component 5 is powered on (first the conduit...), When the pressure in circuit 7 increases, it pushes the contacts of the pilot pneumatic unit 11 to connect the circuit. The solenoid valve 501 magnetically pulls the control diaphragm 502 upward, opening the exhaust port 510. The compressed gas above the blowing diaphragm 504 is discharged to the outside through the exhaust port 510. The pressure above the blowing diaphragm 504 decreases. Under the pulling force of the return spring 503, the blowing diaphragm 504 moves upward, connecting the air inlet 506 and the air outlet 507. The compressed gas is instantly transported from the air storage unit 2 through the dust removal unit 3 to the dust removal pipe 4 and is sprayed out from the gas blowing hole 301, realizing the function of blowing up and disturbing the accumulated dust. After the blow-out, the circuit of the blow-out control component 5 is de-energized (the pressure in the pilot circuit 7 decreases, and the contacts of the pilot pneumatic part 11 return to their original position and disconnect the circuit). The control diaphragm 502 is pressed back onto the upper end of the exhaust port 510 under the action of the solenoid valve spring 509. The pressure on the upper end of the blow-out diaphragm 504 increases and it is pressed back onto the air outlet 507 by the return spring 503, thus ending one blow-out action.

[0050] In practice, a jetting control component 5 is installed, which can convert the compressed gas in the gas storage section 2 into a high-speed airflow to jet the dust in the dust removal pipe 4, effectively removing the dust in the dust removal pipe 4 and avoiding various problems caused by excessive dust accumulation.

[0051] In some embodiments, the gas storage unit 2 is provided with a pressure acquisition unit (not shown in the figure), which can specifically be a pressure sensor structure.

[0052] Specifically, the pressure acquisition unit is electrically connected to the control unit 12 of the dust removal pipe 4 to acquire pressure data inside the gas storage unit 2 and transmit the data to the control unit 12.

[0053] In this embodiment, the gas source 1 is electrically connected to the control unit 12. After acquiring the pressure data, the control unit 12 compares it with a preset threshold range. If the pressure exceeds the threshold range, it sends a shutdown command to the gas source 1; if the pressure is below the threshold range, it sends a start command to the gas source 1.

[0054] Specifically, the threshold range can be set between 1.0MPa and 1.2MPa, so that a high-speed jet airflow of 30m to 60m / s can be formed in the dust removal pipe 4 through the jet control component 5.

[0055] In practice, the pressure acquisition unit and control unit 12 can be used to realize the automatic control of the internal pressure of the gas storage unit 2, so as to prevent the safety problem caused by excessive pressure or the problem of insufficient dust removal due to excessively low pressure.

[0056] The working principle of this automatic dust removal device is as follows: Since the dust accumulation in the dust removal pipeline 4 is the result of the long-term unstable operation of the dust removal system, and in order to save compressed gas consumption, the control unit 12 is shared with the dust removal pipeline 4 system, and the pilot air circuit control unit 9 is opened and closed at timed intervals through program control.

[0057] When there is no dust accumulation in the dust removal duct 4, or the amount of dust accumulation is small, the control unit 12 controls the pilot air path control unit 9 to open and close periodically. When the pilot air path control unit 9 is opened, compressed gas at a lower pressure after depressurization enters the pilot air path 7. Since there is no dust accumulation or very little dust accumulation in the dust removal duct 4, the dust removal unit 3 is connected to the dust removal duct 4, and the dust removal unit 3 is under negative pressure. At this time, a small amount of gas in the pilot air path 7 will pass through the one-way flow section 10 and enter the dust removal unit 3, and finally enter the dust removal duct 4. At this time, the pilot pneumatic unit 11 is not triggered, and the jet blowing control component 5 is in a de-energized state. The pilot air path control unit 9 is opened for a period of time and then closed, and the working process ends.

[0058] When a large amount of dust accumulates in the dust removal duct 4, the dust removal unit 3, located at the bottom of the inner wall of the dust removal duct 4, becomes submerged in dust, and the gas jet nozzle 301 also becomes clogged with dust (when the amount of dust is large, the pressure is high enough to completely block the gas jet nozzle 301). The control unit 12 causes the pilot air path control unit 9 to open and close periodically. When the pilot air path control unit 9 opens, compressed gas at a lower pressure, after being depressurized, enters the pilot air path 7. Because the gas jet nozzle 301 on the dust removal unit 3 is blocked by dust, the gas cannot enter the dust removal unit 3 from the pilot air path 7 and be discharged from the gas jet nozzle 301, causing the pressure in the pilot air path 7 to continuously rise, and the gas pressure is transmitted to the pilot pneumatic unit 11 through the pilot air path 7. When the gas pressure in the pilot air path 7 reaches the operating value of the pilot pneumatic unit 11, the pilot pneumatic unit 11 closes to connect the circuit. The solenoid valve 501 of the jet-blowing control component 5 is activated by the power supply unit 6, allowing high-pressure compressed gas to enter the dust collection pipe 4 directly from the gas storage section 2 through the dust removal unit 3 and be ejected through the gas jet nozzle 301 on the dust removal unit 3. This strongly agitates the dust deposited at the bottom of the pipe, causing it to re-scatter inside the dust collection pipe 4 and be carried into the dust collector by the airflow inside the pipe. After being collected by the dust collector, the dust is transported and processed uniformly. During this operation, the one-way flow section 10 prevents high-pressure compressed gas from reversing into the pilot pipe 7, thus protecting the pilot pneumatic section 11. After the dust removal unit 3 cleans the dust accumulated on its upper part through the high-speed airflow from the gas jet 301, the dust removal unit 3 and the dust removal pipe 4 are reconnected, and the dust removal unit 3 becomes negative pressure. At this time, the gas in the pilot line 7 flows into the dust removal unit 3 through the one-way flow section 10 and finally enters the dust removal pipe 4. The pressure in the pilot line 7 decreases, and the pilot pneumatic unit 11 disconnects the circuit between the power supply unit 6 and the jet control component 5. The jet control component 5 cuts off the connection between the gas storage unit 2 and the dust removal unit 3, and the working process ends.

[0059] In some embodiments, the gas jet hole 301 of the dust removal unit 3 is an adjustable structure.

[0060] Specifically, the dust removal unit 3 located within the dust removal pipe 4 can be constructed as a nested, telescopic structure. The extension and retraction of the inner and outer parts can adjust the number and diameter of the gas jet holes 301. For example, the nested pipes can both have gas jet holes 301. When the inner and outer gas jet holes 301 are aligned, the diameter is at its maximum. When the inner and outer gas jet holes 301 are staggered by a certain distance, the diameter decreases. When the inner and outer gas jet holes 301 are completely staggered, some gas jet holes 301 are completely closed, leaving only a portion of the gas jet holes 301 open. The extension and retraction length can be automatically adjusted by the control unit 12, for example, by adding a motor structure. This configuration allows for adjustment of the airflow velocity for dust particles of different sizes. For smaller dust particles, the diameter of the gas jet holes 301 can be reduced, requiring only a smaller airflow to remove dust. For larger dust particles, a larger diameter and increased airflow velocity are needed to blow away the larger dust particles.

[0061] In practice, adjustable gas jet holes 301 are set up, which can automatically adjust the jet flow rate for different particles, saving energy costs and effectively cleaning accumulated dust.

[0062] In some embodiments, such as Figure 3 As shown, the automatic dust removal device may also include a dust thickness detection unit 13, which is installed inside the dust removal pipe 4 and electrically connected to the control unit 12 of the dust removal pipe 4, for detecting the thickness of the dust accumulation.

[0063] Specifically, existing technologies such as infrared detectors or fiber optic detectors can be used. This embodiment uses a fiber optic detector as an example for illustration.

[0064] Specifically, the fiber optic detector can be vertically installed near the dust removal unit 3 inside the dust removal duct 4, with multiple detection points 131 arranged from low to high. When dust accumulation blocks the lowest fiber optic detection point 131, the fiber optic detector will send a signal to the control unit 12 due to the light blockage at the lowest detection point 131. As the dust accumulation increases, the detection points 131 at higher points are blocked one by one, and each of them will send a signal to the control unit 12. A threshold is set in the control unit 12. When the number of signals sent by the fiber optic detector exceeds the threshold, the control unit 12 sends a command to the pilot air path control unit 9 to open the air path, and then executes the working process of the automatic dust removal device described above.

[0065] Specifically, in the initial stage of dust accumulation, the dust volume is small and the weight is light. Although it can accumulate to a certain thickness, it is still considered floating dust and is easily carried away by the airflow in the dust removal pipe 4. However, as the dust volume increases and the weight increases, the floating dust gradually turns into thick, compacted dust, which can easily cause the aforementioned safety problems. The purpose of setting up the dust thickness detection unit 13 is to transform the control unit 12's periodic sending of the opening command to the pilot air path control unit 9 into the control of the opening timing of the pilot air path control unit 9 based on the dust thickness detected by the dust thickness detection unit 13. In this way, even if the dust thickness reaches the threshold, if it is floating dust, the pressure inside the pipe is still low when the pilot air path 7 is used for detection, and the pilot pneumatic unit 11 will not be activated, thus preventing the dust removal pipe 4 from being blown. Conversely, if the thick dust reaches the threshold height, the pressure inside the pilot air path 7 will increase, activating the pilot pneumatic unit 11 and thus implementing the dust removal action.

[0066] In practice, a dust accumulation thickness detection unit 13 is installed, which uses the dust accumulation thickness as the trigger signal for the pilot circuit 7, rather than simply starting it at a set time. This provides better adaptability to the different amounts of dust emitted by industrial production of different scales and outputs. Furthermore, through the cooperation of the dust accumulation thickness detection unit 13 and the pilot circuit 7, the difference between floating and accumulated dust at the same thickness can be identified. This reduces the ineffective activation of the pilot circuit 7 while ensuring effective dust removal, further saving energy consumption and reducing operating costs.

[0067] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes.
