Abstract
Description
Technical Field
[0001] This invention relates to the field of industrial dust removal, and more particularly to an industrial dust removal device for preventing dust explosions. Background Technology
[0002] Currently, in the industrial sector, dust explosions refer to the violent combustion and explosion phenomenon that occurs when combustible solid dust (such as metals, wood, grains, chemical raw materials, etc.) forms a suspended cloud during processing or storage and reaches a certain concentration, instantly ignited by an open flame, high temperature, or electric spark. The occurrence of such an explosion requires five conditions to be met simultaneously: combustible dust, concentration within the explosive limits, sufficient oxygen, a confined space, and an ignition source. It often generates high temperature, high pressure, and shock waves, easily triggering secondary explosions and causing serious harm to personnel and equipment. It is a key safety risk to be guarded against in industries such as mining, metallurgy, and food processing.
[0003] Currently, in order to prevent dust explosion accidents, some places are equipped with equipment for spraying inhibitors. The equipment usually includes multiple pipelines with nozzles installed. The pipelines are distributed at certain intervals on the ceiling wall of the place. When the dust concentration detector detects that the dust concentration has reached the warning value, it supplies inhibitors into the pipelines, which are then sprayed out through the nozzles to suppress the dust.
[0004] However, there are certain problems with this type of structural design. First, the inhibitor is sprayed from the top and diffuses downwards, but many production workshops have a high internal height, and the dust concentration at the bottom is generally higher than that at the top. There is a certain time interval between the diffusion of the inhibitor from top to bottom. Second, there is some airflow interference in some workshops. In addition, due to the influence of thermal convection, the inhibitor gas is easily interfered with by the gas inside the workshop after it is sprayed out and cannot fall down in time. Therefore, relying solely on the traditional top spraying method makes it difficult for the inhibitor gas to diffuse in time in the lower area of the workshop at the initial stage of the alarm.
[0005] Therefore, it is necessary to provide a new industrial dust removal device to prevent dust explosions and solve the above-mentioned technical problems. Summary of the Invention
[0006] The technical problem solved by this invention is to provide an industrial dust removal device that integrates a top spraying structure and an adjustable spraying structure to allow the inhibitor to diffuse in a timely manner and achieve full coverage in a closed space, thereby preventing dust explosions.
[0007] To solve the above-mentioned technical problems, the present invention provides an industrial dust removal device for preventing dust explosions, comprising: a monitoring and alarm structure, an inhibitor storage structure, a top spraying structure, and an adjustable spraying structure, wherein the inhibitor storage structure is used to supply inhibitors to the top spraying structure and the adjustable spraying structure.
[0008] The top spraying structure includes a main pipe, a plurality of top pipes are installed on the surface of the main pipe, and a plurality of second spray heads are provided on the surface of the top pipes;
[0009] The adjustable spraying structure includes a mounting component, a cover is provided at the bottom of the mounting component, and a plurality of movable pipes are connected to the bottom surface of the cover and evenly distributed around the axis of the cover. A plurality of first spray heads are installed on the surface of the movable pipes. A power structure is connected to the bottom surface of the cover located inside the plurality of movable pipes. The power structure is used to drive the movable pipes to move.
[0010] As a further embodiment of the present invention, one end of the movable pipe facing the cover is hinged to the bottom surface of the cover via a top hinge. The power structure includes an explosion-proof electric push rod, which is fixedly connected to the bottom surface of the cover. A fixing member is fixedly connected to the telescopic end of the explosion-proof electric push rod. A connecting rod is provided between each of the movable pipes and the fixing member. One end of the connecting rod facing the fixing member is hinged to the surface of the fixing member via a second hinge. The other end of the connecting rod facing the movable pipe is hinged to the surface of the movable pipe via a second hinge. A supply pipe is provided on one side of the mounting member. One end of the supply pipe passes through the side wall of the cover and extends into the interior of the cover. An end hose is fixedly connected to the surface of each of the movable pipes. The other end of the end hose passes through the side wall of the cover and is fixedly connected to the surface of the supply pipe on the inside of the cover. The first spray head is fixedly connected to the surface of the movable pipe. The interior of the flow channel of the first spray head, the interior of the movable pipe, the interior of the end hose, and the interior of the supply pipe are sequentially connected to form a continuous fluid channel.
[0011] Through the above technical solution, traditional industrial dust removal structures of this type only use top spraying. Because there is a certain time interval between the top and bottom diffusion of the inhibitor, and some airflow interference exists within the workshop, coupled with the influence of thermal convection, the sprayed inhibitor gas is easily affected by the airflow within the workshop and cannot fall down in time, failing to achieve rapid diffusion and coverage within the enclosed space. In this device, when the dust concentration detector detects that the dust concentration within the enclosed space reaches the warning value, the control module activates valve body one and valve body two. In the structure on one side of valve body one, the inhibitor inside the high-pressure storage cylinder is depressurized by the first and second pressure-reducing valves, enters supply pipe two, and flows into the main pipe and the top pipe, then is sprayed out through several sets of second spray heads installed at the top. The structure diffuses downwards from the top. To ensure the inhibitor can quickly disperse and take effect in the lower and middle layers of the enclosed space, the explosion-proof electric push rod is activated immediately after the dust concentration reaches the warning value. This causes the fixed parts to move downwards. During this process, the connecting rod drives the movable pipes to rotate around the hinge point of the top hinge. This causes several movable pipes, which were originally close to the ceiling, to turn vertically downwards, allowing them to quickly penetrate into the dust. At this time, multiple sets of vertically arranged first spray heads form a ring array structure. The inhibitor entering from one side of the valve body will be sprayed out through the multiple sets of first spray heads, providing a large-area coverage spray to the surrounding space. Combined with the top spray structure, the inhibitor can diffuse in the enclosed space at a faster speed, eliminating the risk of dust explosion.
[0012] As a further embodiment of the present invention, several of the top pipes are fixedly connected to the main pipe, the first spray head is fixedly connected to the top pipe on the adjacent side, and a second supply pipe is fixedly connected to the surface of the main pipe. The interior of the flow channel of the first spray head, the interior of the top pipe, the interior of the main pipe and the interior of the second supply pipe are sequentially connected to form a continuous fluid channel.
[0013] With the above technical solution, the top pipe and installation components in the structure need to be fixed to the ceiling of the enclosed space. The installation components need to be installed in a place with a certain amount of open space below so that the movement of the pipes will not be obstructed. The inhibitor storage structure is set outside the enclosed space and a dedicated person needs to be assigned to one side to monitor the operation of the equipment.
[0014] As a further embodiment of the present invention, the inhibitor storage structure includes a fixed frame, with a plurality of high-pressure storage bottles fixedly connected inside the fixed frame. A manifold is fixedly connected to the top of the fixed frame via a connector. A connecting pipe is fixedly connected between the outlet ends of the plurality of high-pressure storage bottles and the manifold. A first pressure reducing valve is fixedly connected to one end of the manifold. A second pressure reducing valve is fixedly connected to the other end of the first pressure reducing valve via a connecting pipe 1. A connecting pipe 2 is fixedly connected to the other end of the connecting pipe 2. A pressure gauge is fixedly connected to the wall of the connecting pipe 2. The detection end of the pressure gauge is located inside the connecting pipe 2 and the pressure gauge is used to detect the fluid pressure inside the connecting pipe 2. A connecting pipe 1 is fixedly connected to the other end of the connecting pipe 2. The interiors of the outlets of the high-pressure storage bottles, the connecting pipes, the manifold, the first pressure reducing valve, the connecting pipe 1, the second pressure reducing valve, the connecting pipe 2, and the connecting pipe 1 are sequentially connected to form a continuous fluid channel.
[0015] Through the above technical solution, the interior of the high-pressure storage bottle in the structure is used to store inhibitors, the first pressure reducing valve and the second pressure reducing valve can reduce the pressure of the high-pressure gas flow, and the pressure gauge allows users to conveniently monitor the pressure of the fluid flowing through it.
[0016] As a further embodiment of the present invention, a branch pipe 1 and a branch pipe 2 are fixedly connected to the surface of the connecting pipe 1. A valve body 1 and a valve body 2 are respectively fixedly connected to one end of the branch pipe 1 and the branch pipe 2 relative to one end of the connecting pipe 1. The other end of the valve body 2 is fixedly connected to the connecting pipe 2. The end of the supply pipe 1 located outside the cover is fixedly connected to the connecting pipe 2. The end of the supply pipe 2 relative to the main pipe is fixedly connected to the end of the valve body 1. The interior of the supply pipe 2, the interior of the valve body 1, the interior of the branch pipe 1, and the interior of the connecting pipe 1 are sequentially connected to form a continuous fluid channel. The interior of the supply pipe 1, the interior of the connecting pipe 2, the flow channel of the valve body 2, the interior of the branch pipe 2, and the interior of the connecting pipe 1 are sequentially connected to form a continuous fluid channel.
[0017] Through the above technical solution, the device is equipped with two sets of structures: a top spraying structure and an adjustable spraying structure. Based on the top spraying, a second spray head distributed in a ring array on the surface of the movable pipe is used to penetrate into the middle and lower layers of high-concentration dust space. Inhibitors are used to cover a large area of the surrounding space. The combination of the two structures is more effective in preventing dust explosions than the traditional single top spraying structure.
[0018] As a further embodiment of the present invention, the top hinge, hinge one, hinge two, cover and connecting rod are all made of polyetheretherketone material.
[0019] Through the above technical solution, users can use CF30 polyetheretherketone material to make the top hinge, hinge one, hinge two, cover and connecting rod. CF30, which is polyetheretherketone, has a carbon fiber content of 30%, which makes the structure have good explosion-proof effect, extremely low coefficient of thermal expansion and excellent safety.
[0020] As a further embodiment of the present invention, the monitoring and alarm structure includes an audible and visual alarm, a support member is fixedly connected to one side wall surface of the fixed frame, the audible and visual alarm is fixedly connected to the surface of the support member, and several dust concentration detectors are installed at the lower side of the main pipeline and the top pipeline on one side.
[0021] The above technical solution incorporates multiple dust concentration detectors, which are distributed on the walls of the enclosed space to effectively monitor the dust concentration within the space.
[0022] As a further embodiment of the present invention, a control module is fixedly connected to the surface of the support member located on one side of the audible and visual alarm. The dust concentration detector, the audible and visual alarm, the first pressure reducing valve, the second pressure reducing valve, valve body one, valve body two, and the explosion-proof electric push rod are all electrically connected to the control module.
[0023] Through the above technical solution, the device is equipped with a control module, which can be used in conjunction with a top spraying structure and an adjustable spraying structure to spray the inhibitor into the enclosed space, preventing dust explosion accidents.
[0024] Compared with related technologies, the industrial dust removal device for preventing dust explosions provided by the present invention has the following beneficial effects:
[0025] Traditional industrial dust removal structures of this type only use top spraying. Due to the time interval between the top-to-bottom diffusion of the inhibitor, and the interference of airflow in some workshops, coupled with the effects of thermal convection, the sprayed inhibitor gas is easily affected by the airflow within the workshop and cannot fall down in time, failing to achieve rapid diffusion and coverage within the enclosed space. In this device, when the dust concentration detector detects that the dust concentration in the enclosed space reaches the warning value, the control module activates valve body one and valve body two. In the structure on one side of valve body one, the inhibitor inside the high-pressure storage cylinder is depressurized by the first and second pressure-reducing valves, enters supply pipe two, and flows into the main pipe and the top pipe. It is then sprayed out through several sets of second spray heads located at the top, from top to bottom. The structure allows the inhibitor to disperse rapidly and effectively in the lower and middle layers of a confined space. Once the dust concentration reaches a warning level, an explosion-proof electric actuator is activated, causing the fixed component to move downwards. During this process, a connecting rod drives the movable pipes to rotate around the hinge point of the top hinge. This causes several circularly distributed movable pipes, previously flush against the ceiling, to move vertically downwards, allowing them to quickly penetrate the dust. At this point, multiple vertically arranged first spray heads form a circular array. The inhibitor entering from one side of the valve body is sprayed out through these first spray heads, providing a large-area coverage spray to the surrounding space. Combined with the top spray structure, this allows the inhibitor to disperse more quickly in the confined space, eliminating the risk of dust explosion. Attached Figure Description

[0036] The monitoring and alarm structure 4, the inhibitor storage structure 1, the top spraying structure 2, and the adjustable spraying structure 3 are provided. The inhibitor storage structure 1 is used to supply inhibitors to the top spraying structure 2 and the adjustable spraying structure 3.
[0037] The top spraying structure 2 includes a main pipe 32, a plurality of top pipes 30 are installed on the surface of the main pipe 32, and a plurality of second spray heads 31 are provided on the surface of the top pipes 30;
[0038] The adjustable spray structure 3 includes a mounting component 34. A cover 28 is provided at the bottom of the mounting component 34. A plurality of movable pipes 6 are connected to the bottom surface of the cover 28 and are evenly distributed around the axis of the cover 28. A plurality of first spray heads 8 are installed on the surface of the movable pipes 6. A power structure is connected to the bottom surface of the cover 28 located inside the plurality of movable pipes 6. The power structure is used to drive the movable pipes 6 to move.
[0039] like Figures 1-6 As shown, the end of the movable pipe 6 facing the cover 28 is hinged to the bottom surface of the cover 28 via a top hinge. The power structure includes an explosion-proof electric push rod 27, which is fixedly connected to the bottom surface of the cover 28. A fixing member is fixedly connected to the telescopic end of the explosion-proof electric push rod 27. A connecting rod 26 is provided between several movable pipes 6 and the fixing member. The end of the connecting rod 26 facing the fixing member is hinged to the surface of the fixing member via a second hinge 25. The end of the connecting rod 26 facing the movable pipe 6 is hinged to the surface of the movable pipe 6 via a second hinge 25. The mounting part 34 is located at the end of the mounting part. A supply pipe 23 is provided on one side. One end of the supply pipe 23 passes through the side wall of the cover 28 and extends into the interior of the cover 28. Several movable pipes 6 are fixedly connected to end hoses 29. The other end of the end hoses 29 passes through the side wall of the cover 28 and is fixedly connected to the surface of the supply pipe 23 inside the cover 28. The first spray head 8 is fixedly connected to the surface of the movable pipe 6. The interior of the flow channel of the first spray head 8, the interior of the movable pipe 6, the interior of the end hoses 29, and the interior of the supply pipe 23 are sequentially connected to form a continuous fluid channel.
[0040] Traditional industrial dust removal structures of this type only use top spraying. Due to the time interval between the top-down diffusion of the inhibitor and the presence of airflow interference within some workshops, coupled with the effects of thermal convection, the sprayed inhibitor gas is easily affected by the airflow within the workshop and cannot fall down in time, failing to achieve rapid diffusion and coverage within the enclosed space. In this device, when the dust concentration detector 7 detects that the dust concentration inside the enclosed space reaches the warning value, the control module 5 activates valve body 20 and valve body 21. In the structure on one side of valve body 20, the inhibitor inside the high-pressure storage cylinder 10 is depressurized by the first pressure reducing valve 14 and the second pressure reducing valve 15, enters the second supply pipe 33, and flows into the main pipe 32 and the top pipe 30, and then is sprayed out through several sets of top-mounted second spray heads 31. The structure diffuses downwards from the top. To ensure the inhibitor can quickly disperse and take effect in the lower and middle layers of the enclosed space, the explosion-proof electric push rod 27 is activated immediately after the dust concentration reaches the warning value. This causes the fixing part to move downwards. During this process, the connecting rod 26 drives the movable pipe 6 to rotate around the hinge point of the top hinge. This causes the several movable pipes 6, which were originally close to the ceiling, to turn vertically downwards, allowing the movable pipes 6 to quickly penetrate into the dust. At this time, multiple sets of vertically arranged first spray heads 8 form a ring array structure. The inhibitor that enters from one side of the valve body 21 will be sprayed out through the multiple sets of first spray heads 8, providing a large-area coverage spray to the surrounding space. With the cooperation of the top spray structure 2, the inhibitor can diffuse in the enclosed space at a faster speed, eliminating the risk of dust explosion.
[0041] like Figures 1-6 As shown, several top pipes 30 are fixedly connected to the main pipe 32, the first spray head 8 is fixedly connected to the top pipe 30 on the adjacent side, and the surface of the main pipe 32 is fixedly connected to the supply pipe 2 33. The interior of the flow channel of the first spray head 8, the interior of the top pipe 30, the interior of the main pipe 32 and the interior of the supply pipe 2 33 are sequentially connected to form a continuous fluid channel.
[0042] The top pipe 30 and the mounting component 34 in the structure need to be fixed to the ceiling of the enclosed space. The mounting component 34 needs to be installed in a place with a certain amount of open space below so that the movement of the active pipe 6 will not be obstructed. The inhibitor storage structure 1 is set outside the enclosed space and a dedicated person needs to be assigned to one side to monitor the operation of the equipment.
[0043] like Figures 1-6As shown, the inhibitor storage structure 1 includes a fixed frame 9, with several high-pressure storage bottles 10 fixedly connected inside the fixed frame 9. A manifold 11 is fixedly connected to the top of the fixed frame 9 via a connector. A connecting pipe 12 is fixedly connected between the outlet ends of the several high-pressure storage bottles 10 and the manifold 11. A first pressure reducing valve 14 is fixedly connected to one end of the manifold 11. A second pressure reducing valve 15 is fixedly connected to the other end of the first pressure reducing valve 14 via a connecting pipe 1. A connecting pipe 2 is fixedly connected to the other end of the second pressure reducing valve 15. A pressure gauge 16 is fixedly connected to the wall of the connecting pipe 2. The detection end of the pressure gauge 16 is located inside the connecting pipe 2 and the pressure gauge 16 is used to detect the fluid pressure inside the connecting pipe 2. A connecting pipe 17 is fixedly connected to the other end of the connecting pipe 2. The interiors of the outlets of the high-pressure storage bottles 10, the connecting pipe 12, the manifold 11, the first pressure reducing valve 14, the connecting pipe 1, the second pressure reducing valve 15, the connecting pipe 2, and the connecting pipe 17 are sequentially connected to form a continuous fluid channel.
[0044] The high-pressure storage bottle 10 is used to store inhibitors. The first pressure reducing valve 14 and the second pressure reducing valve 15 can reduce the pressure of the high-pressure gas flow, while the pressure gauge 16 allows users to monitor the pressure of the fluid flowing through it.
[0045] like Figures 1-6 As shown, branch pipe 18 and branch pipe 2 19 are fixedly connected to the surface of connecting pipe 17. One end of branch pipe 18 and branch pipe 2 19 relative to one end of connecting pipe 17 are respectively fixedly connected to valve body 1 20 and valve body 2 21. The other end of valve body 2 21 is fixedly connected to connecting pipe 2 22. The end of supply pipe 1 23 located outside the cover 28 is fixedly connected to connecting pipe 2 22. One end of supply pipe 2 33 relative to the main pipe 32 is fixedly connected to the end of valve body 1 20. The interior of supply pipe 2 33, the interior of valve body 20, the interior of branch pipe 18 and the interior of connecting pipe 17 are sequentially connected to form a continuous fluid channel. The interior of supply pipe 2 23, the interior of connecting pipe 2 22, the flow channel of valve body 2 21, the interior of branch pipe 2 19 and the interior of connecting pipe 17 are sequentially connected to form a continuous fluid channel.
[0046] The device is equipped with two sets of structures: a top spraying structure 2 and an adjustable spraying structure. Based on the top spraying, the second spray head 31, which is distributed in a ring array on the surface of the movable pipe 6, penetrates into the middle and lower layers of high-concentration dust space and uses inhibitors to cover a large area of the surrounding space. The combination of the two structures is more effective in preventing dust explosions than the traditional single top spraying structure.
[0047] like Figures 1-6As shown, the top hinge, hinge 1 24, hinge 2 25, cover 28 and connecting rod 26 are all made of polyetheretherketone (PEEK).
[0048] Users can use CF30 polyetheretherketone material to make the top hinge, hinge 1 24, hinge 2 25, cover 28 and connecting rod 26. CF30, which is polyetheretherketone, has a carbon fiber content of 30%, which makes the structure have good explosion-proof effect, extremely low coefficient of thermal expansion and excellent safety.
[0049] like Figures 1-6 As shown, the monitoring and alarm structure 4 includes an audible and visual alarm 13. A support is fixedly connected to one side wall surface of the mounting bracket 9. The audible and visual alarm 13 is fixedly connected to the surface of the support. Several dust concentration detectors 7 are installed at the lower side of the main pipe 32 and the top pipe 30 on one side.
[0050] The structure is equipped with multiple dust concentration detectors 7, which are distributed on the walls of various locations within the enclosed space to effectively monitor the dust concentration in the space.
[0051] like Figures 1-6 As shown, a control module 5 is fixedly connected to the surface of the support component located on one side of the audible and visual alarm 13. The dust concentration detector 7, the audible and visual alarm 13, the first pressure reducing valve 14, the second pressure reducing valve 15, the valve body 1 20, the valve body 2 21, and the explosion-proof electric push rod 27 are all electrically connected to the control module 5.
[0052] The device is equipped with a control module 5, which can be used in conjunction with the top spraying structure 2 and the adjustable spraying structure 3 to spray the inhibitor into the enclosed space to prevent dust explosion accidents.
[0053] The working principle of the industrial dust removal device for preventing dust explosions provided by this invention is as follows:
[0054] Traditional industrial dust removal structures of this type only use top spraying. Due to the time interval between the top-down diffusion of the inhibitor and the presence of airflow interference within some workshops, coupled with the effects of thermal convection, the sprayed inhibitor gas is easily affected by the airflow within the workshop and cannot fall down in time, failing to achieve rapid diffusion and coverage within the enclosed space. In this device, when the dust concentration detector 7 detects that the dust concentration inside the enclosed space reaches the warning value, the control module 5 activates valve body 20 and valve body 21. In the structure on one side of valve body 20, the inhibitor inside the high-pressure storage cylinder 10 is depressurized by the first pressure reducing valve 14 and the second pressure reducing valve 15, enters the second supply pipe 33, and flows into the main pipe 32 and the top pipe 30, and then is sprayed out through several sets of top-mounted second spray heads 31. The structure diffuses downwards from the top. To ensure the inhibitor can quickly disperse and take effect in the lower and middle layers of the enclosed space, the explosion-proof electric push rod 27 is activated immediately after the dust concentration reaches the warning value. This causes the fixing part to move downwards. During this process, the connecting rod 26 drives the movable pipe 6 to rotate around the hinge point of the top hinge. This causes the several movable pipes 6, which were originally close to the ceiling, to turn vertically downwards, allowing the movable pipes 6 to quickly penetrate into the dust. At this time, multiple sets of vertically arranged first spray heads 8 form a ring array structure. The inhibitor that enters from one side of the valve body 21 will be sprayed out through the multiple sets of first spray heads 8, providing a large-area coverage spray to the surrounding space. With the cooperation of the top spray structure 2, the inhibitor can diffuse in the enclosed space at a faster speed, eliminating the risk of dust explosion.
