Description

Technical Field

[0001] This utility model relates to the field of dust removal devices, specifically to a dust removal device for a crusher. Background Technology

[0002] In modern industrial production, dust collection devices are widely used as important environmental protection equipment in various technical fields, especially in industries involving dust generation. The main function of dust collection devices is to effectively collect and treat dust generated during production processes to reduce environmental pollution, protect worker health, and improve production efficiency and product quality. Crushers and shredders typically generate large amounts of dust during material handling, especially at the feeding, discharging, and bagging stages of crushers, as well as at the feed inlet of shredders, all of which are high-concentration dust areas. Therefore, dust collection devices are commonly used for dust removal.

[0003] However, existing dust collection devices for crushers still have some significant shortcomings in practical applications. First, some dust collection devices are poorly designed, resulting in low dust collection efficiency and an inability to effectively capture all generated dust, especially when dealing with high-concentration dust mixed with large and small particles. Second, the suction end of some dust collection devices is prone to clogging, requiring frequent shutdowns for cleaning or filter replacement. This not only increases maintenance costs but also affects the continuity and efficiency of production. Therefore, developing a new, more efficient, and reliable dust collection device for crushers is of great significance for promoting the green development of related industries. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned defects and provide a dust removal device for a crusher, so as to solve the technical problems in the prior art of low dust collection efficiency, difficulty in effectively capturing dust, and easy blockage at the dust collection end, which affects the dust removal efficiency and continuity.

[0005] The objective of this utility model is achieved through the following means:

[0006] A dust removal device for a crusher includes a dust collector with a filter chamber inside. The dust collector has a suction port and an exhaust port on its side that communicate with the filter chamber. The filter chamber is divided into an exhaust chamber and a filter chamber by a partition. A filter element is detachably connected to the partition through a connecting hole. The suction port communicates with the filter chamber, allowing dust-laden gas to enter the filter chamber and then the filter element, passing through the connecting hole into the exhaust chamber. The suction port is connected to a suction pipe with multiple connecting pipes. The ends of the connecting pipes extend towards the crusher and are connected to the crusher via a guide hood. The end of the guide hood away from the connecting pipes forms a conical, horn-shaped guide opening. The other end of the guide hood is paired with the connecting pipe via an installation end. The inner wall of the guide opening has several protruding guide plates, one end of which extends towards the installation end. A spirally arranged vortex plate is welded to the inner wall of the installation end.

[0007] Furthermore, as described above, the exhaust port is located at the top of the dust collector and is connected to the exhaust chamber. A drive fan is installed inside the exhaust chamber. The suction end of the drive fan is connected to the connection hole on the partition, and the exhaust end of the drive fan is connected to the exhaust port.

[0008] By placing the exhaust port at the top of the dust collector and using it in conjunction with the drive fan, the filtered clean gas can be effectively guided out, forming a reasonable airflow channel. This helps to improve the dust collection and exhaust efficiency of the entire dust collection system, allowing dust-laden gas to be better drawn in, filtered, and discharged, reducing gas retention in the device, and enhancing the dust collection device's ability to capture and process dust.

[0009] Furthermore, as described above, the filter chamber is equipped with a dust collection hood for collecting dust, and the dust collector has a dust discharge port on its side that communicates with the filter chamber. The dust discharge port is connected to a slidable dust collection hopper, which is positioned below the dust collection hood.

[0010] The filter chamber is equipped with a dust collection hood and a sliding dust collection hopper, which can collect dust separated from the dust-laden gas during the filtration process in a timely and effective manner, preventing dust from accumulating in the filter chamber and affecting the dust removal effect. The sliding dust collection hopper design facilitates dust cleaning, reduces the possibility of dust accumulation causing blockage at the suction end, lowers maintenance costs, and ensures production continuity and efficiency.

[0011] Furthermore, as described above, an electrical control box is connected to the side of the dust collector, and a differential pressure gauge for detecting the pressure of the filter chamber is installed on the side of the dust collector.

[0012] The electrical control box connected to the side of the dust collector facilitates centralized control and operation of the entire dust collection device, improving ease of use and automation.

[0013] Optionally, a differential pressure gauge can be installed to monitor the pressure in the filter chamber in real time. When the pressure is abnormal, it can promptly reflect the clogging of components such as the filter element or other potential problems, allowing operators to take timely measures, such as cleaning or replacing the filter material, to avoid affecting the dust removal effect and production efficiency due to clogging and other problems, and to ensure the stable and efficient operation of the equipment.

[0014] Furthermore, as described above, the inside of the suction port is provided with a mesh screen for isolation, and a spark catcher is provided inside the suction port.

[0015] A mesh screen inside the suction port can initially isolate large particles of debris entering the suction port, preventing them from entering the subsequent filtration system and causing blockages, thus reducing maintenance frequency.

[0016] Installing a spark arrestor can effectively capture sparks that may enter with dust-laden gas, preventing sparks from entering the dust collector and causing safety accidents such as dust explosions. This ensures the safety of the dust collection device and related production environment, and improves the safety and reliability of the device's operation.

[0017] Furthermore, as described above, the flow guide covers the dust outlet of the crusher by wrapping it with a silicone curtain.

[0018] The guide hood wraps around the dust inlet of the crusher with a silicone curtain, which can better seal the dust inlet and prevent dust from leaking out from the gap between the dust inlet and the guide hood. This improves dust collection efficiency and ensures that the generated dust can be more effectively sucked into the dust collection pipe for dust removal. It also reduces dust overflow and environmental pollution, further enhances the dust collection effect of the dust removal device, and ensures the green and environmentally friendly nature of production.

[0019] The beneficial effects of this utility model are as follows: The dust suction port connects to the dust suction pipe, and by setting multiple connecting pipes on the dust suction pipe, it can be used to adapt to the dust removal of multiple crushers. The end of the connecting pipe is connected to the crusher through a guide hood. The end of the guide hood forms a conical funnel-shaped guide port, which can increase the dust suction area and more effectively collect the dust generated by the crusher. At the same time, the inner wall of the guide port forms a raised guide plate, and the inner wall of the mounting end is welded with a spirally arranged vortex plate. The design of the guide plate and vortex plate can guide the dust-laden gas to form a spiral airflow state when entering the connecting pipe, which helps to evenly disperse the dust and smoothly introduce it into the pipe, reduce the accumulation of dust at the dust suction end, and reduce the dust adhesion to the inner wall of the guide hood, thereby reducing the possibility of blockage and ensuring that the dust-laden gas enters the connecting pipe smoothly, reducing the phenomenon of blockage at the dust suction end, and ensuring dust removal efficiency and continuity.

The suction port 2 is connected to a suction pipe 7, and the suction pipe 7 is equipped with… A connecting pipe 8 is provided, the end of which extends toward the crusher and is connected to the crusher through a guide shroud 9. The end of the guide shroud 9 away from the connecting pipe 8 forms a conical funnel-shaped guide port 10, and the other end of the guide shroud 9 is paired and inserted with the connecting pipe 8 through an installation end 11. A protruding guide plate 12 is formed on the inner wall of the guide port 10, and the guide plate 12 is distributed around the inner wall of the guide port 10. One end of the guide plate 12 extends toward the installation end 11, and a spirally arranged vortex plate 13 is welded to the inner wall of the installation end 11.

[0031] By placing the exhaust port 3 at the top of the dust collector 1 and cooperating with the drive fan 14, the filtered clean gas can be effectively guided out, forming a reasonable airflow channel. This helps to improve the dust collection and exhaust efficiency of the entire dust collection system, allowing the dust-laden gas to be better drawn in, filtered and discharged, reducing the gas retention in the device, and enhancing the dust collection device's ability to capture and process dust.

[0032] Specifically, in this embodiment, the drive fan 14 has a power of 11KW and an air volume of 10000m³. 3 Centrifugal fan with a pressure of 5000 Pa / h.

[0033] The filter chamber 5 is equipped with a dust collection hood 15 for collecting dust. The dust collector 1 has a dust discharge port 16 on its side that communicates with the filter chamber 5. The dust discharge port 16 is connected to a slidable dust collection hopper 17, so that the dust collection hopper 17 is located below the dust collection hood 15.

[0034] A dust collection hood 15 is installed inside the filter chamber 5, along with a sliding dust collection hopper 17. This allows for timely and effective collection of dust separated from the dust-laden gas during the filtration process, preventing dust accumulation within the filter chamber 5 and ensuring optimal dust removal efficiency. The sliding design of the dust collection hopper 17 facilitates dust cleaning, reduces the likelihood of dust accumulation clogging the suction end, lowers maintenance costs, and ensures continuous and efficient production.

[0035] The dust collector 1 is connected to an electrical control box 18 on its side, and a differential pressure gauge 19 for detecting the pressure of the filter chamber is provided on the side of the dust collector 1.

[0036] The dust collector 1 is connected to the electrical control box 18 on the side, which facilitates centralized control and operation of the entire dust collection device, improving the convenience and automation of use.

[0037] Optionally, a differential pressure gauge 19 can be set to detect the pressure in the filter chamber in real time. When the pressure is abnormal, it can promptly reflect the blockage of components such as the filter element 6 or other potential problems, so that operators can take timely measures, such as cleaning or replacing the filter material, to avoid affecting the dust removal effect and production efficiency due to blockage and other problems, and ensure the stable and efficient operation of the device.

[0038] The suction port 2 is equipped with a mesh screen 22 for isolation, and a spark catcher 21 is installed inside the suction port 2.

[0039] The dust inlet 2 is equipped with a mesh screen 22, which can initially isolate large particles of debris entering the dust inlet 2, preventing them from entering the subsequent filtration system and causing blockage, thus reducing the frequency of maintenance.

[0040] The spark catcher 21 can effectively capture sparks that may enter with dust-laden gas, preventing sparks from entering the dust collector 1 and causing safety accidents such as dust explosions, thus ensuring the safety of the dust collection device and the production environment, and improving the safety and reliability of the device operation.

[0041] The flow guide shroud 9 wraps around the dust outlet 16 of the crusher with a silicone curtain.

[0042] The guide hood 9 wraps around the dust inlet of the crusher with a silicone curtain, which can better seal the dust inlet and prevent dust from leaking from the gap between the dust inlet and the guide hood 9.

It also further enhances the dust collection effect of the dust removal device and ensures the green and environmentally friendly nature of production.

[0043] The specific dust removal process used in this embodiment is as follows:

The end of the guide hood 9 forms a conical funnel-shaped guide port 10, which increases the dust collection area and more effectively collects the dust generated by the crusher. At the same time, the inner wall of the guide port 10 forms a raised guide plate 12, and the inner wall of the mounting end 11 is welded with a spirally arranged vortex plate 13. The arrangement of the guide plate 12 and the vortex plate 13 can guide the dust-laden gas to form a spiral airflow state when entering the connecting pipe 8, which helps to evenly disperse the dust and smoothly guide it into the dust collection pipe 7, reduce the accumulation of dust at the dust collection end, and reduce the dust adhesion to the inner wall of the guide hood 9, thereby reducing the possibility of blockage. The drive fan 14 is driven to ensure that the dust-laden gas enters the connecting pipe 8 smoothly. When the dust-laden gas passes through the dust collection pipe 7 and enters the filter chamber 5, the filter element 6 filters and separates the dust-laden gas, so that the clean gas is discharged from the exhaust port 3, ensuring dust removal efficiency and continuity.
