Description
Technical Field
[0001] The utility model relates to the technical field of dust removal equipment, in particular to a high-efficiency pulse dust removal equipment. Background Art
[0002] In modern industrial production, pulse dust removal equipment is widely used in various dust-generating areas to remove dust, improve the working environment, reduce air pollution, and ensure normal operation of the equipment. Existing pulse dust removal systems primarily rely on pulsed gas jets to remove dust from the filter bags. However, this cleaning method is ineffective for highly adherent dust. Incomplete cleaning not only reduces dust removal efficiency but also decreases filter bag permeability, increases system operating resistance, shortens the filter bag life, and ultimately affects the overall performance of the dust removal system.
[0003] Chinese patent document CN221230154U discloses a pulse dust removal device with a filter bag replacement structure, and proposes to clean the middle and lower boxes of the pulse dust removal device by setting up a water tank, a water pump, a water pipe and a nozzle. However, this technical solution is difficult to apply to the removal of dust with strong adhesion attached to the surface of the filter bag: on the one hand, the flushing method is difficult to completely remove the dust on the surface of the filter bag. In particular, for dust with strong adhesion, the impact force of the water flow may not be enough to completely wash it off. Instead, it is easy to cause the dust to further adhere to the filter bag fibers, making the dust more difficult to remove, thereby further reducing the air permeability and cleaning effect of the filter bag; on the other hand, even after flushing with a high-pressure water source, moisture will remain on the surface of the filter bag, which not only requires additional drying treatment, but also continues production operations when the filter bag is not completely dry, causing dust to adhere to the wet filter bag surface again, further reducing the dust removal efficiency. At the same time, the humid environment will also have an adverse effect on the filter bag material, shortening the service life of the filter bag, and thus affecting the operation effect and stability of the entire dust removal equipment.

[0040] Pulse dust removal equipment can be applied in a variety of industrial fields. Take the mining industry, for example. With the continuous development of coal mining, the demand for waste rock filling and treatment in my country has increased year by year. The high amount of waste rock dust generated during the waste rock crushing process requires a more efficient dust removal solution. The high-efficiency pulse dust removal equipment provided by this utility model can be used to achieve efficient dust removal during waste rock processing, solving the technical problem of poor filter bag cleaning performance in existing technologies.
[0041] The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments. Each example is provided by way of explanation of the present application and does not limit the present application. In fact, it will be clear to those skilled in the art that modifications and variations can be made in the present application without departing from the scope or spirit of the present application. For example, a feature shown or described as part of one embodiment can be used in another embodiment to produce yet another embodiment. Therefore, it is expected that the present application includes such modifications and variations within the scope of the appended claims and their equivalents.
[0042] In the description of this application, the terms "longitudinal", "transverse", "upper", "lower", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this application and do not require that this application must be constructed and operated in a specific orientation. Therefore, they should not be understood as limitations on this application. The terms "connected", "connected", and "set" used in this application should be understood in a broad sense. For example, they can be fixed connections or detachable connections; they can be directly connected or indirectly connected through intermediate components. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.
[0043] Example 1:
[0044] like Figures 1 to 6 As shown, a high-efficiency pulse dust removal device includes an ash hopper 1, which is fixed by a base frame 2 and arranged below a dust removal chamber 3. A pulse chamber 4 is provided above the dust removal chamber 3, and the pulse chamber 4 is connected to a negative pressure fan 5 and a first pulse spraying device 6;
[0045] A dust filter bag 31 is provided inside the dust removal chamber 3. The side wall of the dust filter bag 31 is connected to a plurality of flapping members 311. The top of the dust filter bag 31 is connected to the bottom of the pulse chamber 4.
[0046] When the negative pressure fan 5 is turned on, the dust-laden gas enters the ash hopper 1 from the first air inlet 11 and then continues upward into the dust removal chamber 3 to be filtered by the dust removal filter bag 31. The filtered gas enters the pulse chamber 4 and is discharged through the exhaust port 51 of the negative pressure fan 5.
[0047] When the first pulse blowing device 6 is turned on, the pulse gas ejected by the first pulse blowing device 6 enters the dust filter bag 31 from the pulse chamber 4. The dust filter bag 31 vibrates under the action of the pulse gas, and the flapping member 311 vibrates accordingly and flaps the side wall of the dust filter bag 31 to make the dust attached to the dust filter bag 31 fall off.
[0048] During specific implementation, when the negative pressure fan 5 is turned on, the dust-laden gas enters the ash hopper 1 from the first air inlet 11 and continues upward to enter the dust removal chamber 3. At this time, the dust filter bag 31 is in a filtering state, and the dust is blocked on the outside of the dust filter bag 31. The filtered gas enters the pulse chamber 4 and is discharged to the fan exhaust duct 52 through the exhaust port 51 of the negative pressure fan 5. The fan exhaust duct 52 and the exhaust port 51 of the negative pressure fan 5 can be connected by a hose, a metal pipe or a plastic pipe. This connection method not only ensures smooth exhaust, but also has a certain degree of flexibility and adaptability, which facilitates the installation and layout of the equipment. The negative pressure fan 5 can be driven by a variable frequency motor. The advantage of variable frequency is that the fan speed can be adjusted according to the actual working conditions to achieve energy-saving operation. At the same time, it can also reduce the number of starts and stops of the fan and extend the service life of the fan.
[0049] When the first pulse jet device 6 is turned on, the ejected pulse gas enters the pulse chamber 4 and then enters the dust filter bag 31, causing the dust filter bag 31 to vibrate. The flapping member 311 then vibrates and flaps the sidewalls of the dust filter bag 31, thereby causing the dust attached to the outside of the dust filter bag 31 to fall off and enter the ash hopper 1, and also causing the dust inside the dust filter bag 31 with a particle size smaller than the filter hole to fall off and be deposited at the bottom of the dust filter bag 31. The specific structure of the flapping member 31 can be designed to be spherical, hemispherical or other smooth block-shaped. The flapping member 311 can be prefabricated as one piece with the dust filter bag 31, or it can be connected to the dust filter bag 31 via a detachable connector.
[0050] Currently, common pulse dust removal equipment mainly relies on a single pulse gas injection for cleaning. However, the utility model adds a flapping member 311 to clean the dust filter bag 31 from multiple dimensions, which can greatly improve the cleaning efficiency. The cleaning effect of this combination of flapping and pulse is far superior to that of a single method. It can effectively solve the problem of poor cleaning effect of the dust filter bag 31 without increasing too much cost and complex structure, thereby extending the service life of the dust filter bag 31 and improving the operating efficiency and stability of the entire dust removal equipment.
[0051] Example 2:
[0052] Furthermore, a vibration generator 32 is provided inside the dust removal chamber 3. The vibration generator 32 is arranged between two or more dust removal filter bags 31. A vibration wave generating port 321 is provided on the vibration generator 32.
[0053] When the vibration generator 32 is turned on, the vibration wave is transmitted from the vibration wave generating port 321 to the dust filter bag 31 to remove the dust attached to the dust filter bag 31 .
[0054] During specific use, the specific shape of the vibration generator 32 can be designed to be plate-shaped, which can use a vibration pump as a power source and be installed between two or more dust filter bags 31 in the dust removal chamber 3 through a connector. The vibration wave generating port 321 on the vibration generator 32 corresponds to the position of the dust filter bag 31. When the vibration generator 32 is turned on, the vibration pump of the vibration generator 32 drives the vibration plate to vibrate, and the vibration wave is transmitted to the dust filter bag 31 through the vibration wave generating port 321, thereby causing the dust attached to the dust filter bag 31 to fall off. This design of the vibration generator 32 can clean the dust on the dust filter bag 31 more comprehensively, especially for some parts that are difficult to clean by patting or pulse blowing, it can also achieve a good cleaning effect.
[0055] The vibration generator 32 is applied to the pulse dust removal equipment and together with the flapping member 311 and the first pulse blowing device 6, a multi-dimensional cleaning system is formed to form a unique collaborative cleaning mechanism, which can more thoroughly clean the dust on the dust filter bag 31, greatly improve the cleaning efficiency and the regeneration performance of the dust filter bag 31, and effectively solve the problems in the prior art such as incomplete cleaning of the dust filter bag 31, which easily leads to decreased air permeability and increased operating resistance.
[0056] Example 3:
[0057] Furthermore, the beating member 311 includes a beating ball, which is hung on the side wall of the dust filter bag 31 through a hook.
[0058] In practice, the beating ball can be hung on the side wall of the dust filter bag 31 via a hook. More specifically, a hook mounting area specifically for the beating ball can be provided on the side wall of the dust filter bag 31 to ensure a secure hang. The beating ball has a smooth surface, and the beating action will not damage the dust filter bag 31. Furthermore, the beating ball can be reused, reducing equipment maintenance costs and the frequency of dust filter bag 31 replacement.
[0059] Example 4:
[0060] Furthermore, a chamber cover plate 41 is detachably connected to the top of the pulse chamber 4, and a second pulse spray device 7 and a suction device 8 are connected to the top of the chamber cover plate 41. The suction device 8 is connected to the second air inlet 12 of the ash hopper 1 through a pipeline;
[0061] When the second pulse spraying device 7 and the suction device 8 are turned on at the same time, the pulse gas sprayed by the second pulse spraying device 7 lifts up the dust deposited inside the pulse chamber 4 and is then sucked to the second air inlet 12 by the suction device 8 .
[0062] During specific implementation, the power source of the suction device 8 can be a vacuum pump, or other devices capable of generating negative pressure, such as a centrifugal fan, etc. When the second pulse spraying device 7 and the suction device 8 are turned on at the same time, the pulse gas ejected by the second pulse spraying device 7 can lift the dust deposited inside the pulse chamber 4. At this time, the negative pressure generated by the suction device 8 sucks the lifted dust into the ash hopper 1 through the pipeline connected to the second air inlet 12 of the ash hopper 1, thereby effectively cleaning the dust accumulated in the pulse chamber 4 and preventing excessive dust accumulation from affecting the normal operation of the pulse chamber 4.
[0063] Conventional pulse dust removal equipment often relies on manual or simple blowing to clean dust accumulated in the pulse chamber 4, resulting in poor cleaning results and a low degree of automation. However, the present invention cleverly incorporates a second pulse jet device 7 and a suction device 8, utilizing the synergistic effect of the pulse gas impact and negative pressure suction to achieve efficient and automatic cleaning of dust accumulated in the pulse chamber 4. This effectively resolves the difficulty in cleaning dust accumulated in the pulse chamber 4 in the prior art, improving the automation level and long-term operational stability of the equipment.
[0064] Example 5:
[0065] Furthermore, the dust removal chamber 3 and the pulse chamber 4 are encapsulated in the dust removal body box 9 . A body box base 91 is provided at the bottom of the dust removal body box 9 . The body box base 91 is detachably connected to the base frame 2 .
[0066] In specific implementation, in large-scale industrial application scenarios, the dust removal chamber 3 and the pulse chamber 4 are often set at a high position, which makes it very inconvenient to perform operations such as equipment maintenance and replacement of dust filter bags 31. The present invention encapsulates the dust removal chamber 3 and the pulse chamber 4 in the dust removal body box 9, and makes the body box base 91 detachably connected to the base frame 2 (for example, by bolts). In this way, when the equipment needs to be repaired or the dust filter bags 31 are replaced, the dust removal body box 9 can be easily removed from the base frame 2. Depending on the specific size of the equipment, the dust removal body box 9 can be moved to a suitable position for operation by hoisting, forklift transportation, sliding movement, etc., which greatly reduces the difficulty and risk of inspection and maintenance and improves work efficiency.
[0067] Example 6:
[0068] Furthermore, a slide rail 21 is connected to one side of the base frame 2 , and a pulley 911 is connected to the main body box base 91 . The pulley 911 cooperates with the slide rail 21 so that the dust removal main body box 9 can move along the slide rail 21 .
[0069] In specific implementation, the slide rail 21 connected to one side of the base frame 2 can be connected to the base frame 2 at a fixed angle (such as Figure 4 As shown), it can also be foldable and angle-adjustable connected to the base frame 2 (as shown Figure 1 The dust collector housing 9 is designed to be easily adjusted and stored according to different locations and operational requirements. Pulleys 911 connected to the housing base 91 cooperate with the slide rails 21, allowing the dust collector housing 9 to move smoothly along the slide rails 21. When the equipment needs to be repaired or the dust filter bags 31 need to be replaced, the dust collector housing 9 can simply be moved along the slide rails 21 to the appropriate position. This greatly improves operational convenience and flexibility, especially in applications with limited space or where frequent equipment movement is required.
[0070] Example 7:
[0071] Furthermore, an anti-blocking scraper 13 and a scraper power source 14 for driving the anti-blocking scraper 13 are connected to the bottom of the ash hopper 1 .
[0072] In practice, the anti-blocking scraper 13 is driven by a scraper power source 14 to reciprocate at the bottom of the ash hopper 1, thereby scraping dust accumulated in the ash hopper 1 toward the discharge port 15, preventing dust from clogging the ash hopper 1. The scraper power source 14 can be an electric motor, a hydraulic motor, or a pneumatic motor, etc. These power sources can provide stable and reliable driving force for the anti-blocking scraper 13, ensuring its normal operation. For example, when an electric motor is used as the power source, the speed and torque can be adjusted by a speed reducer, so that the anti-blocking scraper 13 can scrape the material at an appropriate speed and force, effectively preventing clogging of the ash hopper 1 and ensuring smooth dust discharge.
[0073] Example 8:
[0074] Furthermore, a discharge valve 16 is provided above the discharge port 15 of the ash hopper 1 , and the discharge valve 16 is connected to a discharge power source 17 .
[0075] In a specific implementation, the discharge power source 17 can be an electric motor, a hydraulic motor, or a pneumatic motor, and its function is to control the opening and closing of the discharge valve 16, thereby opening and closing the discharge port 15 of the ash hopper 1. When the dust in the ash hopper 1 accumulates to a certain amount, the discharge power source 17 can be controlled to open the discharge valve 16, allowing the dust to be discharged through the discharge port 15, completing the collection and treatment of the dust.
[0076] Example 9:
[0077] Furthermore, the first pulse jet device 6 includes an air bag 61 and an electromagnetic pulse valve 62;
[0078] When the electromagnetic pulse valve 62 is opened, the compressed air in the air bag 61 is released to form pulse gas.
[0079] In specific implementation, the benefit of setting up the air bag 61 is that it can store a certain amount of compressed air and provide a stable and reliable air source for the electromagnetic pulse valve 62. The compressed air in the air bag 61 can come from the factory's compressed air system. When the electromagnetic pulse valve 62 is opened, the compressed air in the air bag 61 is released to form high-pressure pulse gas, which enters the dust filter bag 31, causing the dust filter bag 31 to expand and vibrate instantaneously, thereby effectively cleaning the dust on the dust filter bag 31. The setting of the air bag 61 can ensure sufficient air volume and air pressure required for pulse spraying, improve the cleaning effect, and also help to stabilize the operation of the entire first pulse spraying system, reducing problems such as fluctuations in the cleaning effect caused by unstable air source.
[0080] Example 10:
[0081] Furthermore, a dust detection device 33 for monitoring the dust concentration in the dust removal chamber 3 is provided inside the dust removal chamber 3 .
[0082] In practice, two or more dust detection devices 33 can be provided, for example, one at the top and one at the bottom of the dust removal chamber 3, to more comprehensively monitor the dust concentration distribution within the chamber 3. The dust detection devices 33 can employ conventional laser scattering dust sensors, capacitive dust sensors, or beta-ray dust sensors. Equipped with the dust detection devices 33, the high-efficiency pulse dust removal equipment provided by the present invention can achieve "intelligent detection," namely, real-time monitoring of the dust concentration within the chamber 3 and feedback of this data to an automated control system (such as a PLC system, DCS system, or other control system). Based on the dust concentration monitoring data, the automated control system can automatically adjust the frequency and intensity of the pulse jets, as well as the operating status of cleaning components such as the vibration generator 32 and the beating element 311, to achieve precise cleaning and energy-saving operation. For example, when a high dust concentration is detected, the control system can increase the frequency and intensity of the pulse jets and simultaneously activate the vibration generator 32 for enhanced cleaning. When the dust concentration is low, the pulse jet frequency can be reduced to reduce energy consumption.
[0083] Based on the technical solutions provided in the above embodiments, the high-efficiency pulse dust removal equipment of the present invention can be operated as follows during specific use:
[0084] When the high-efficiency pulse dust removal equipment is working, the negative pressure fan 5 is turned on, the pulse chamber 4 and the dust removal chamber 3 form a negative pressure environment, the dust-laden airflow enters the ash hopper 1 through the first air inlet 11, and the dust-laden airflow passes through the dust removal chamber 3 and is filtered out by the dust removal filter bag 31.
[0085] According to the setting of the control system, the electromagnetic pulse valve 62 can pulse out the compressed air in the air bag 61 at a regular time, and clean the dust on the surface of the dust filter bag 31 into the ash hopper 1. During the pulse process, the dust filter bag 31 will vibrate, and then the flapping piece 311 will vibrate, and the dust will fall off under the flapping of the flapping piece 311.
[0086] When the dust detection intelligent device detects that the dust concentration in the dust removal chamber 3 is too high, indicating that the dust is difficult to clean, the control system can feedback a signal to the vibration generator 32. Upon receiving the signal, the vibration generator 32 emits a vibration wave through the vibration wave generating port 321 to clean the dust on the dust removal filter bag 31 into the ash hopper 1.
[0087] When the dust filter bag 31 is replaced, the mounting bolts of the dust collector box 9 can be removed, and the dust collector box 9 can be moved on the slide rail 21 by the pulley 911 to move the dust collector box 9 to the ground or other platform to replace the dust filter bag 31.
[0088] After the dust removal equipment has been used for a period of time, dust will fall and accumulate in the pulse chamber 4. In order to clean up the accumulated dust, the second pulse blowing device 7 can blow gas into the pulse chamber 4 through the air intake pulse pipe to lift the dust in the pulse chamber 4, and the suction device 8 discharges the dust into the ash hopper 1 through the pipeline.
[0089] When the discharge port 15 of the ash hopper 1 is opened for ash cleaning, the anti-blocking scraper 13 can assist in cleaning the ash hopper 1 under the power provided by the scraper power source 14.
[0090] In summary, the present invention can be applied to industrial dust removal scenarios to solve the technical problems in the prior art of poor cleaning effect and difficulty in replacement of the dust removal filter bag 31.
[0091] It should be noted that in order to clearly demonstrate the structural relationship of the internal key components of the present invention, some pipelines, lines and other components of the actual product are omitted in the drawings. However, the specific design schemes of these omitted components are easily implemented by ordinary technicians in this field based on the technical scheme currently given in this utility model combined with conventional designs.
[0092] The above are only preferred embodiments of the present application and are not intended to limit the present application. For those skilled in the art, various modifications and variations of the present application are possible. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present application shall be included in the scope of protection of the present application.
