Description

Technical Field

[0001] This utility model relates to the field of ore dust removal technology, specifically an energy-saving pulse dust removal device for ore crushers. Background Technology

[0002] Ore crushing operations generate a large amount of dust, which, if directly released into the atmosphere, will cause serious air pollution. Energy-saving pulse dust collectors can efficiently capture and collect this dust, greatly reducing the amount of dust emitted into the environment, helping to improve surrounding air quality and reduce environmental problems such as smog.

[0003] Uncontrolled dust emissions can damage surrounding ecosystems such as soil, water bodies, and vegetation. Using pulse jet dust collectors can reduce the impact of dust on the ecological environment, protect biodiversity, and maintain ecological balance.

[0004] Baghouse dust collection is a common dust removal method for ore crushers. During operation, the baghouse system can be affected by external factors, such as insufficient pulse jet pressure or inaccurate timing, which can prevent the complete removal of dust adhering to the bags, leading to a buildup of dust on the bag surface and increased system resistance. Furthermore, highly adhesive dust can also cause cleaning difficulties. Therefore, this application provides an energy-saving pulse jet dust collector for ore crushers. Utility Model Content

The telescopic components and the fixed ring maintain a fixed distance to form a striking area for treating the attached dust.

[0010] As a further improvement of this utility model, a fixing frame is provided on the inner side of the flow guide at the junction with the support rod. A positioning hole is provided in the middle of the fixing frame, and the positioning hole is inserted and adapted to one end of the vibration tube.

[0011] As a further improvement of this utility model, the bottom of the top cover is provided with a clamping inner ring located inside the support rod. The inner side of the clamping inner ring is connected to the end of the cloth bag for fixing the cloth bag.

However, it should be understood that these physical details should not be used to limit the present invention. That is, in some embodiments of the present invention, these physical details are not essential.

[0017] Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0018] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 Ore crushing operations generate a large amount of dust, which, if emitted directly, will cause serious air pollution, leading to environmental problems such as smog. It will also damage the surrounding soil, water bodies, vegetation, and other ecosystems, affecting biodiversity and ecological balance.

[0019] Baghouse dust collection is a common dust removal method for ore crushers, but its baghouse system is affected by external factors during operation and has some problems. For example, insufficient pulse jet pressure or inaccurate timing may fail to completely remove dust from the bags, causing dust accumulation and increasing system resistance; high dust viscosity can also make cleaning difficult. To solve these problems, this application proposes an energy-saving pulse jet dust collector for ore crushers, including a dust collector 1 for dust treatment, an air outlet 2 on one side of the dust collector 1, and a negative pressure air inlet 4 on the other side of the dust collector 1 for conveying dust-containing airflow. The bottom of the dust collector 1 is provided with a dust outlet 3 for discharging the filtered dust. Dust collector 1 includes an inner cavity 13, and one or more bag filter assemblies 11 are disposed inside the inner cavity 13. The bag filter assembly 11 includes a sleeve area 111 consisting of one or more support rods 113, and a filter bag is sleeved on the outside of the sleeve area 111. One or more fixing rings 112 are sleeved on the inner side of the support rod 113, and the outer side of the fixing ring 112 is fixed to the outer side of the support rod 113 by a fastener 115. A flow guide 114 is provided at the bottom of the sleeve area 111, and a top cover 117 is provided at the top of the sleeve area 111. The top of the top cover 117 is through-hole, and a fixing frame 1112 is provided in the through-hole area of ​​the top cover 117. An inner plate 1111 is installed on the inner side of the fixing frame, and a pulse jet nozzle 118 is provided in the middle of the inner plate 1111.

[0020] The air inlet is located on one side of the dust collector 1. Its function is to use negative pressure to transport the dust-laden airflow generated by the ore crusher into the interior of the dust collector 1. During the ore crushing operation, a large amount of dust-laden gas generated by the crusher enters the inner cavity 13 of the dust collector 1 from the air inlet under the action of negative pressure for subsequent dust treatment.

[0021] The air outlet 2 is located on the other side of the dust collector 1. The clean gas that has been filtered by the dust collector 1 will be discharged into the atmosphere through the air outlet 2. This design can ensure that the airflow has a more reasonable flow path within the dust collector 1, thereby improving the dust removal efficiency.

[0022] The dust outlet 3 is located at the bottom of the dust collector 1. When the dust-laden airflow passes through the filter bag inside the dust collector 1, the dust will be trapped on the surface of the filter bag. Over time, the dust that accumulates to a certain extent will be discharged through the dust outlet 3 to a special collection device under the action of gravity, so as to achieve centralized treatment of the dust.

[0023] The inner cavity 13 serves as the main space for the dust collector 1, providing a space for dust handling. One or more dust collectors 1 are arranged inside the inner cavity 13, and these dust collectors 1 are the key components for achieving dust filtration.

[0024] The sleeved area 111 consists of one or more support rods 113, with a filter bag sleeved on its outer side. In practical applications, after the dust-laden airflow enters the inner cavity 13, it passes through the filter bag. The dust is intercepted by the filter bag, while the clean gas continues to flow through the filter bag. The support rods 113 serve to support the filter bag, preventing it from deforming under the action of airflow and ensuring that the filter bag can work normally.

[0025] The fixing ring 112 is sleeved on the inner side of the support rod 113, and its outer side is fixed to the outer side of the support rod 113 by the fastener 115. The function of the fixing ring 112 is to further enhance the stability of the support rod 113, ensure the structural firmness of the sleeved area 111, and prevent the support rod 113 from shifting or deforming during long-term use, thereby ensuring the normal filtration function of the filter bag.

[0026] The guide hood 114 is located at the bottom of the sleeve area 111, and its function is to guide the dust-laden airflow into the bag area evenly. When the dust-laden airflow enters the inner cavity 13 from the negative pressure air inlet 4, the guide hood 114 can disperse the airflow and prevent the airflow from concentrating and impacting a certain part of the bag, thereby extending the service life of the bag.

[0027] The top cover 117 is located on top of the sleeve area 111, and its top is through-hole. A fixing frame 1112 is provided in the through-hole area of ​​the top cover 117. An inner plate 1111 is installed inside the fixing frame 1112, and a pulse jet nozzle 118 is provided in the center of the inner plate 1111. When the filter bag needs to be cleaned, the pulse jet nozzle 118 will spray a pulsed airflow to blow off the dust adhering to the surface of the filter bag, restoring the filter bag's filtration performance.

[0028] Work process When the ore crusher starts working, the dust-laden airflow generated enters the inner cavity 13 of the dust collector 1 through the negative pressure inlet 4 under negative pressure. The airflow is first guided by the guide hood 114 and evenly enters the casing area 111 of the bag filter assembly 11. The dust-laden airflow passes through the filter bags, the dust is intercepted by the filter bags, and the clean gas passes through the filter bags and is discharged from the outlet 2. Over time, dust gradually accumulates on the surface of the filter bags. When it reaches a certain level, the pulse jet nozzle 118 will spray a pulse airflow to clean the filter bags, causing the dust to fall to the bottom of the dust collector 1 and be discharged through the dust outlet 3.

[0029] Through the above structure and working process, the energy-saving pulse dust collector for this ore crusher can effectively treat the dust generated during the ore crushing process. At the same time, through reasonable structural design, it achieves the purpose of energy saving while ensuring the dust removal effect.

[0030] Please see Figure 3 , Figure 4 , Figure 5 , Figure 6 as well as Figure 7 The dust collector 1 is arranged at intervals. The top of the inner cavity 13 is provided with a sealing cover to seal the inner cavity 13. The bottom of the inner cavity 13 is provided with an air chamber 12, and the bottom of the air chamber 12 is connected to the outlet.

[0031] The dust collectors 1 are spaced apart in the inner cavity 13 of the dust collector 1. After the dust-laden airflow enters the inner cavity 13, the spaced dust collectors 1 can make the airflow pass through each filter bag more evenly. If the dust collectors 1 are arranged closely, the airflow may concentrate and pass through some filter bags, causing these filter bags to be overloaded, the filtration effect to decrease, and they are easily damaged. The spaced arrangement allows each filter bag to fully play its filtration role, improving the overall dust removal efficiency. At the same time, the spaced arrangement is also beneficial to the pulse airflow during pulse cleaning, which can act more evenly on each filter bag and effectively remove the dust attached to the surface of the filter bag.

[0032] A sealing cover is installed at the top of the inner cavity 13, its main function being to seal the inner cavity 13. During normal operation of the equipment, the sealing cover prevents dust-laden airflow from leaking out from the top of the inner cavity 13, ensuring the airtightness of the entire dust removal process. This prevents dust from escaping into the surrounding environment, further improving the dust removal efficiency. The sealing cover can be installed by bolts or other connecting parts to ensure a tight connection with the top of the inner cavity 13, ensuring it will not loosen during equipment operation. When it is necessary to inspect or replace components such as the dust collector 1 inside the inner cavity 13, the sealing cover can be opened for easy operation by personnel.

[0033] A dust chamber 12 is located at the bottom of the inner cavity 13, serving as a buffer and collection mechanism. When the dust-laden airflow passes through the bag filter, the dust falls downwards under gravity. The dust chamber 12 provides a temporary collection space for this falling dust. The bottom of the dust chamber 12 connects to the dust outlet 3, and the dust collected in the dust chamber 12 is discharged to an external collection device through the dust outlet 3. The presence of the dust chamber 12 prevents dust from directly accumulating at the bottom of the dust collector 1, avoiding excessive dust accumulation that could affect the normal operation of the equipment. Simultaneously, the dust chamber 12 also buffers the airflow, allowing it to flow more stably towards the dust outlet 3, thus improving the efficiency of dust discharge.

[0034] When the dust-laden airflow generated by the ore crusher enters the inner cavity 13 of the dust collector 1 through the negative pressure inlet 4, the airflow passes evenly through the spaced-apart dust collector 1. The dust is intercepted by the filter bags, while the clean gas continues to flow upward and is discharged from the outlet 2. During this process, the sealing cover ensures the airtightness of the inner cavity 13, preventing dust leakage. As filtration progresses, the dust on the surface of the filter bags gradually increases. When cleaning is required, the pulse jet nozzle 118 sprays pulsed airflow to clean the filter bags, and the dust falls into the air chamber 12. The dust in the air chamber 12 will continuously accumulate, and when it reaches a certain amount, it will be discharged into the external collection device through the dust outlet 3 connected to the bottom of the air chamber 12, completing the entire dust removal process.

[0035] Please see Figure 6 , Figure 7 , Figure 8 , Figure 9 A vibration tube 116 is connected to the outside of the pulse jet nozzle 118, and the bottom of the vibration tube 116 extends to the junction of the flow guide shroud 114 and the support rod 113.

[0036] Through holes are provided on the outer side of the vibrating tube 116 and the fixed ring 112 respectively, and telescopic components are installed. The telescopic components and the fixed ring 112 maintain a fixed distance to form a striking area for treating the attached dust.

[0037] A fixing frame 1110 is provided on the inner side of the flow guide 114 at the junction with the support rod 113. A positioning hole is provided in the middle of the fixing frame 1110, and the positioning hole is inserted and matched with one end of the vibration tube 116.

[0038] The bottom of the top cover 117 is provided with a clamping inner ring 119 located inside the support rod 113. The inner side of the clamping inner ring 119 is connected to the end of the cloth bag for fixing the cloth bag.

[0039] A vibrating tube 116 is connected to the outside of the pulse jet nozzle 118. The bottom of the vibrating tube 116 extends to the junction of the guide shroud 114 and the support rod 113. When the pulse jet nozzle 118 sprays pulsed airflow for dust removal, this airflow not only directly blows off the dust on the surface of the filter bag, but also causes the vibrating tube 116 connected to the outside to vibrate. This vibration can be transmitted along the vibrating tube 116 to the entire bag filter assembly 11, further assisting in the removal of firmly attached dust on the filter bag. For example, some dust that is difficult to be blown off directly by the pulsed airflow due to its high stickiness can be loosened by the vibration of the vibrating tube 116, making it easier to remove.

[0040] Each of the outer sides of the vibrating tube 116 and the fixed ring 112 has a through hole corresponding to one another, and a telescopic component is installed thereon. A fixed distance is maintained between the telescopic component and the fixed ring 112, forming a striking area. When the pulse jet nozzle 118 operates to vibrate the vibrating tube 116, the telescopic component will extend and retract under the action of vibration. When the telescopic component extends, it will collide with the fixed ring 112 within the striking area. The impact force generated by this collision is transmitted to the support rod 113 and the filter bag, causing the filter bag to shake. This helps to shake off dust adhering to the inside and surface of the filter bag, especially for dust accumulated in the folds or crevices of the filter bag. The vibration generated by the collision between the telescopic component and the fixed ring 112 can more effectively remove it, improving the dust removal effect.

[0041] A fixing bracket 1110 is provided on the inner side of the deflector 114 at the junction with the support rod 113. A positioning hole is provided in the middle of the fixing bracket 1110, which is inserted and fitted to one end of the vibrating tube 116. The fixing bracket 1110 serves to fix and support the vibrating tube 116. When the vibrating tube 116 vibrates under the action of pulsed airflow, the positioning hole ensures the stability of the bottom position of the vibrating tube 116, preventing the vibrating tube 116 from shifting or shaking excessively during vibration. At the same time, this plug-in fitting design facilitates the installation and disassembly of the vibrating tube 116, making it easier to operate when the vibrating tube 116 or other components need to be inspected or replaced.

[0042] The bottom of the top cover 117, located inside the support rod 113, is equipped with a clamping inner ring 119. The inner side of the clamping inner ring 119 connects to the end of the filter bag to secure it. During equipment operation, the dust-laden airflow exerts a certain impact force on the filter bag, which may cause the bag to shift or loosen. The clamping inner ring 119 can tightly clamp the end of the filter bag, ensuring that the bag maintains a stable position under the impact of the airflow. This ensures that the relative position of the filter bag and components such as the support rod 113 remains unchanged, allowing the filter bag to perform its filtering function normally. It also facilitates the effectiveness of pulse cleaning and vibration cleaning, preventing the cleaning and filtration efficiency from being affected by the loosening of the filter bag.

[0043] When the ore crusher operates, it generates dust-laden airflow, which enters the inner cavity 13 of the dust collector 1 through the negative pressure inlet 4. The airflow passes through the spaced-apart dust collectors 1 for filtration. As filtration proceeds, dust accumulates on the surface of the filter bags. At this time, the pulse jet nozzle 118 sprays pulsed airflow, which directly blows off some of the dust on the surface of the filter bags and causes the connected vibrating tube 116 to vibrate. The vibration of the vibrating tube 116 causes the telescopic component to collide with the fixing ring 112 in the impact area, and the resulting impact force helps to remove dust from the filter bags. At the same time, the fixing frame 1110 ensures the stability of the bottom of the vibrating tube 116 through the positioning hole, while the clamping inner ring 119 ensures that the ends of the filter bags are fixed, so that the entire bag dust collector assembly 11 operates stably. The filtered clean gas is discharged from the outlet 2, and the filtered dust falls into the air chamber 12 and is discharged through the dust outlet 3, completing the entire dust removal and cleaning process.

[0044] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 as well as Figure 5 A pipe 21 is provided at the air outlet 2, and a fan 23 is installed on the outside of the pipe 21. An air outlet pipe 22 is provided at one end of the fan 23 to discharge the airflow after dust filtration.

[0045] A pipe 21 is installed at the air outlet 2, which connects the air outlet 2 to the fan 23. After the dust-laden airflow passes through the filter bag in the inner cavity 13 of the dust collector 1, the clean gas flows out from the air outlet 2 and enters the pipe 21. The pipe 21 can be made of a sturdy and corrosion-resistant metal, such as stainless steel, and is noise-reducing treated to ensure that it will not be damaged by the composition of the gas or external environmental factors during long-term use. The inner diameter of the pipe 21 is designed according to the air volume of the equipment to ensure that the airflow can flow smoothly in the pipe 21 and avoid airflow obstruction due to the pipe diameter being too small, which would affect the overall operating efficiency of the dust collection equipment.

[0046] A fan 23 is installed on the outside of the duct 21, and the fan 23 is the power source for the airflow of the entire dust removal equipment. The fan 23 generates negative pressure through its operation, allowing the dust-laden airflow to be drawn into the inner cavity 13 of the dust collector 1 from the negative pressure inlet 4. After the clean gas enters the duct 21 from the outlet 2, the fan 23 continues to provide power, propelling the gas through the duct 21. The power of the fan 23 is selected based on the scale and air volume of the dust removal equipment. If the power is too low, it may not provide sufficient suction to allow the dust-laden airflow to enter the dust collector 1 smoothly, or it may not be able to effectively discharge the clean gas; if the power is too high, it will result in energy waste. During operation, the impeller inside the fan 23 rotates at high speed, drawing gas from the duct 21 and accelerating it, providing sufficient power for the gas flow.

[0047] One end of the fan 23 is equipped with an air outlet duct 22, which discharges the airflow after dust filtration into the external environment. The length and direction of the air outlet duct 22 can be adjusted according to the actual installation environment and emission requirements. The outlet of the air outlet duct 22 can be located away from areas with high personnel activity or high air quality requirements to avoid the exhaust gas from affecting the surrounding environment. The material of the air outlet duct 22 also needs to have a certain degree of corrosion resistance and strength to ensure its stability during long-term use. At the outlet of the air outlet duct 22, some filter devices or silencers can also be installed to further improve the quality of the exhaust gas and reduce the noise generated by the fan 23 during operation.

[0048] When the ore crusher generates dust-laden airflow, under the negative pressure generated by the fan 23, the dust-laden airflow enters the inner cavity 13 of the dust collector 1 through the negative pressure inlet 4. The airflow passes through a bag filter, where dust is intercepted, and clean gas enters the pipe 21 from the outlet 2. The fan 23 continues to operate, providing power for the gas flow in the pipe 21, drawing in and accelerating the clean gas, and then discharging it into the external environment through the outlet pipe 22. Throughout this process, the pipe 21 ensures unobstructed gas flow, the fan 23 provides the power for the airflow, and the outlet pipe 22 safely and efficiently discharges the clean gas. Working in conjunction with the other components, this process completes the dust removal task during the ore crushing process.

[0049] The above description is merely an embodiment of this utility model and is not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art.
