Description

Technical Field

[0001] This utility model relates to the field of environmentally friendly dust removal technology, and in particular to an environmentally friendly dust removal device. Background Technology

[0002] In modern industrial production processes, various production activities generate a large amount of dust-laden gas. If this dust-laden gas is directly emitted into the atmosphere without effective treatment, it will not only pollute the surrounding environment and harm the ecological balance, but also pose a threat to human health, causing various health problems such as respiratory diseases. Therefore, the importance of environmentally friendly dust removal devices in industrial production and environmental protection is becoming increasingly prominent. With the continuous improvement of environmental protection requirements and the continuous expansion of industrial production scale, more stringent standards have been put forward for the performance and efficiency of dust removal devices. Environmentally friendly dust removal devices not only need to have high-efficiency dust removal capabilities, effectively separating and collecting dust from dust-laden gas, but also need to reduce energy consumption and reduce secondary pollution to the environment during operation. At the same time, in order to adapt to different production processes and operating conditions, dust removal devices should also have good flexibility and adaptability, and be able to adjust the dust removal strategy in real time according to the actual situation.

[0003] There are many types of dust removal devices in the existing technology, the most common of which are gravity settling dust collectors, inertial dust collectors, cyclone dust collectors, wet dust collectors, and bag dust collectors. Gravity settling dust collectors mainly rely on the gravity of the dust itself to allow the dust to settle naturally in the gravitational field, thereby achieving gas-solid separation. Its mechanical structure is usually relatively simple, mainly consisting of a large settling chamber. After the dust-laden gas enters the settling chamber, the flow velocity decreases, and the dust gradually settles to the bottom of the chamber under the action of gravity. Bag dust collectors, on the other hand, use woven fiber bags to filter the dust-laden gas, so that the dust is intercepted on the surface of the bags, and the clean gas is discharged through the bags.

[0004] However, existing dust removal devices generally suffer from energy waste during operation. In pulse jet cleaning systems, due to unstable airflow, compressed air often fails to form a stable and continuous airflow when entering the filter bags. Some compressed air may leak or flow back, resulting in poor cleaning performance. To achieve the desired cleaning effect, the supply of compressed air must be increased, leading to significant energy waste. This not only increases the operating costs of enterprises but also contradicts the current trend of energy conservation and environmental protection. Furthermore, unstable airflow affects the service life of filter bags, and frequent pressure fluctuations can damage them, increasing maintenance costs and replacement frequency. Moreover, due to unstable airflow, it is difficult to achieve precise control of the dust removal process, making it difficult to effectively improve the automation efficiency of the dust removal device and meet the demands of modern industrial production for efficient, stable, and intelligent dust removal. Therefore, an environmentally friendly dust removal device is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an environmentally friendly dust removal device, which aims to improve the problem of energy waste caused by unstable airflow in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] An environmentally friendly dust removal device includes a dust collector, a dust collection box fixedly connected to the top of the dust collector, an air inlet pipe fixedly connected to one side of the dust collector, a dust cleaner fixedly connected to the other side of the dust collector, a housing provided on the side wall of the dust cleaner, a check valve assembly provided inside the housing, a filter bag provided inside the dust collector, a detector provided inside the dust collector, and a disassembly assembly provided on the outer wall of the detector.

[0008] The check valve assembly includes a suspended ball, the outer wall of which is slidably connected to the inside of the housing. An air inlet is provided inside the housing. A fixing post is fixedly connected to the side wall of the suspended ball. A spring is sleeved on the outer wall of the fixing post. One end of the spring is fixedly connected to the inside of the housing, and the other end of the spring is fixedly connected to the side wall of the suspended ball. A sliding groove is provided inside the housing, and the outer wall of the fixing post is slidably connected to the inside of the sliding groove.

[0009] As a further description of the above technical solution:

[0010] The assembly / disassembly assembly includes a top post, one side of which is disposed on the side wall of the detector.

[0011] As a further description of the above technical solution:

[0012] The dust collector has an outer shell fixedly connected inside, and a sliding block is slidably connected inside the outer shell.

[0013] As a further description of the above technical solution:

[0014] The outer shell has a second sliding groove inside, and the sliding block is rotatably connected to a cam.

[0015] As a further description of the above technical solution:

[0016] The outer wall of the cam is slidably connected inside the second slide groove, and a limit block is provided inside the outer shell.

[0017] As a further description of the above technical solution:

[0018] A limiting groove is formed inside the cam, and the outer wall of the limiting block is slidably connected to the inside of the limiting groove.

[0019] As a further description of the above technical solution:

[0020] The sliding block has a second limiting groove inside, the outer wall of the limiting block is slidably connected to the second limiting groove, and the side wall of the sliding block is fixedly connected to the other side of the top column.

[0021] This utility model has the following beneficial effects:

[0022] 1. In this utility model, when gas enters from the air inlet, it pushes the suspended ball to move, drives the fixed column to move and compresses the spring, and then drives the fixed column to slide in the slide groove. At this time, the valve opens and the gas enters smoothly, and then the filter bag is dusted. This achieves the effect of forming a stable and continuous airflow for the incoming gas and preventing backflow, avoiding the problem of energy waste caused by unstable airflow and improving automation efficiency.

[0023] 2. In this utility model, by moving the cam, the cam drives the limiting block to move, so that it slides in the limiting groove one. At the same time, the outer wall of the limiting block slides in the limiting groove two. When the limiting groove one of the cam rotates to be flush with the limiting groove two, the top column disengages from the side wall of the detector, thus completing the effect of quick disassembly of the detector. This solves the problem that traditional dust removal devices cannot adjust the dust removal strategy in real time, and enhances flexibility and adaptability. Attached Figure Description

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 - Figure 3 This utility model provides an embodiment of an environmentally friendly dust removal device, comprising a dust collector 1, a dust collection box 2 fixedly connected to the top of the dust collector 1, the dust collection box 2 being made of high-strength, corrosion-resistant metal material, and having undergone special rust-proofing treatment inside, capable of long-term and stable collection and storage of dust removed from filter bags 6; an air inlet pipe 3 fixedly connected to one side of the dust collector 1, the air inlet pipe 3 being funnel-shaped and made of high-quality engineering plastic material, possessing good wear resistance and impact resistance; and a dust cleaning machine 4 fixedly connected to the other side of the dust collector 1, the dust cleaning machine 4 cooperating with the dust collector 1 to periodically clean the filter bags 6. The dust removal operation achieves the effect of maintaining the good filtration performance of filter bag 6 and extending the service life of filter bag 6. This is the existing technology and will not be described in detail here. The side wall of the dust removal machine 4 is equipped with a shell 5, and the shell 5 is equipped with a check valve component. The dust collector 1 is equipped with a filter bag 6. The filter bag 6 is made of high-performance fiber filter material, which has good filtration accuracy and air permeability. The filter bag 6 cooperates with the airflow channel inside the dust collector 1 to filter the incoming dust-laden gas, achieving the effect of efficient separation of dust and purification of gas. The dust collector 1 is equipped with a detector 11, and the outer wall of the detector 11 is equipped with a disassembly and assembly component.

[0033] The check valve assembly includes a suspended ball 7, which is made of lightweight, corrosion-resistant plastic with a smooth surface. Its outer wall can slide flexibly inside the housing 5. The outer wall of the suspended ball 7 is slidably connected to the inside of the housing 5. An air inlet 19 is provided inside the housing 5. A fixing post 8 is fixedly connected to the side wall of the suspended ball 7. A spring 9 is sleeved on the outer wall of the fixing post 8. One end of the spring 9 is fixedly connected to the inside of the housing 5, and the other end of the spring 9 is fixedly connected to the side wall of the suspended ball 7. When the suspended ball 7 is displaced under the action of airflow, it drives the fixing post 8 to move and compress the spring 9. The fixing post 8 slides in conjunction with the slide groove 10, achieving the effect of precisely controlling the opening and closing of the valve. When the spring 9 is compressed to a certain extent, the valve opens, and the gas enters smoothly, achieving effective control of the gas flow, avoiding backflow of airflow, and achieving the effect of stabilizing the airflow supply and improving energy utilization efficiency. The inside of the housing 5 is provided with a slide groove 10, and the outer wall of the fixing post 8 is slidably connected inside the slide groove 10.

[0034] Specifically, when the environmentally friendly dust removal device is working, the dust-laden gas first enters the device through the inlet pipe 3. In the filtration zone, the filter bags 6 trap the dust, and the clean gas is discharged from the outlet. As filtration proceeds, the dust on the filter bags 6 increases, the dust removal machine 4 starts, and then the gas enters the dust collection box 2, and finally is discharged through the ash removal device, achieving efficient dust removal. In the automated operation system of the environmentally friendly bag dust collector 1, when the dust-laden gas rushes in from the inlet 19, the force of the airflow pushes the suspended ball 7 to move. The movement of the suspended ball 7 drives the fixed column 8 connected to it to move synchronously. During the movement, the fixed column 8 compresses the spring 9 to make it... The compressed air is deformed and slides smoothly within the slide groove 10. At this time, the valve opens, allowing the gas to enter smoothly. After the gas passes through, the spring 9 rebounds due to its elasticity, causing the suspended ball 7 to move in the opposite direction. Finally, the suspended ball 7 is precisely locked inside the air inlet 19, achieving a good sealing effect. This ensures that the compressed air can be concentrated and effectively used for pulse cleaning, avoiding energy loss caused by gas leakage. This not only improves energy utilization efficiency and reduces operating costs, but also makes the operation of the automated system more stable and efficient, providing a strong guarantee for the continuous and reliable operation of the environmentally friendly dust collector 1.

[0035] Reference Figure 1 , Figure 2 , Figure 4 and Figure 5The assembly and disassembly components include a top column 18, one side of which is mounted on the side wall of the detector 11. Precise dimensional design and surface treatment ensure a tight connection and good conductivity with the detector 11. An outer shell 12 is fixedly connected inside the dust collector 1. The outer shell 12 is made of robust cast iron, possessing good rigidity and stability, providing reliable protection and support for other internal components. A sliding block 13 is slidably connected inside the outer shell 12. The sliding block 13 is made of lightweight but high-strength aluminum alloy, and its shape is optimized to fit the internal space of the outer shell 12. The sliding block 13 moves in conjunction with the outer shell 12, achieving flexible position adjustment and providing a foundation for subsequent operations. A groove 20 is provided inside the outer shell 12, providing precise guidance for the movement of the cam 14 and the sliding block 13. The sliding block 13 is rotatably connected to... Cam 14 is slidably connected to the inside of slide groove 20. Cam 14 cooperates with slide groove 20 to slide and rotate, achieving the effect of converting rotational motion into linear motion and controlling the action of other components. Limit block 16 is set inside the outer shell 12. Limit groove 15 is opened inside cam 14. The outer wall of limit block 16 is slidably connected to the inside of limit groove 15. Limit groove 2 17 is opened inside sliding block 13. The outer wall of limit block 16 is slidably connected to the inside of limit groove 2 17, further enhancing the control and limitation of the movement of sliding block 13, achieving the effect of improving the stability and accuracy of movement. The side wall of sliding block 13 is fixedly connected to the other side of top column 18, achieving the effect of quickly and conveniently completing the disassembly and installation of detector 11, facilitating real-time adjustment of dust removal strategy, and improving the flexibility and adaptability of the entire environmentally friendly dust removal device.

[0036] Specifically, in the automated system of the environmentally friendly bag filter dust collector 1, the disassembly and assembly component is located inside the dust collector 1. When the dust generation situation changes during the production process and the dust removal strategy needs to be adjusted in real time, the operator can start the disassembly process by turning the cam 14. When the cam 14 rotates, it will drive the connected limit block 16 to move. The limit block 16 slides in the first limit groove 15 on one side and its outer wall also slides in the second limit groove 17 on the other side. When the cam 14 continues to rotate, so that the first limit groove 15 rotates to the position flush with the second limit groove 17, the top column 18, which was originally in a fixed state, will disengage from the side wall of the detector 11. At this time, the disassembly operation of the detector 11 can be completed smoothly. By disassembling and replacing the detector 11 or adjusting the parameters, the changes in dust generation situation can be responded to quickly, and the dust removal strategy can be adjusted in time. This not only improves the automation level of the entire production system, but also enhances the environmental protection performance, ensuring that the bag filter dust collector 1 always operates efficiently and stably.

[0037] Working principle: This check valve structure is located on the side wall of the dust removal machine 4. When gas enters from the air inlet 19, it causes the suspended ball 7 to move, which in turn causes the fixed column 8 to move. This causes the spring 9 to be compressed, so that the fixed column 8 slides inside the slide groove 10. At this time, the valve opens, allowing gas to enter. Then, due to the elastic change of the spring 9 itself, the spring 9 rebounds, which then causes the suspended ball 7 to move horizontally and get stuck inside the air inlet 19, thereby achieving a seal. This allows compressed air to be used more effectively for pulse dust removal, improving energy utilization efficiency, reducing operating costs, and also helping to maintain the overall operating efficiency of the automation system.

[0038] The disassembly and assembly structure is located inside the dust collector 1. When it is necessary to adjust the dust removal strategy in real time according to the dust generation situation, the cam 14 is moved, which drives the limit block 16 to move. Then, the limit block 16 slides in the first limit groove 15, and the outer wall of the limit block 16 slides in the second limit groove 17. When the first limit groove 15 in the cam 14 rotates to be flush with the second limit groove 17, the top column 18 is disengaged from the side wall of the detector 11, thus realizing the disassembly of the detector 11. Only then can the real-time adjustment of the dust removal strategy be completed, improving the automation level and environmental performance of the entire production system.

[0039] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
