Description

Technical Field

[0001] This invention belongs to the field of dust removal technology, specifically an intelligent integrated dust removal machine for explosion-proof locations. Background Technology

[0002] Explosion-proof areas refer to work areas where flammable substances (gases, dust, vapors, or fibers) mixed with air may form an explosive atmosphere, requiring special protective measures to ensure safety. Their core characteristic is the presence of ignition risk, necessitating measures to reduce the probability of explosion through equipment selection, engineering design, and safety management.

[0003] Traditional dust removal equipment has the following problems when used in explosion-proof environments: when the dust removal equipment discharges ash using a single valve, outside air may mix with the equipment's internal components, potentially introducing oxygen or sparks and increasing the risk of explosion; at the same time, the single-valve structure makes it difficult to achieve complete airtightness during opening and closing, leading to dust leakage or continuous infiltration of outside air, forming an explosive mixture; the system lacks sealing devices such as dual ash discharge valves or rotary airlocks, making it impossible to establish an effective pressure isolation barrier, resulting in poor ash discharge sealing. Therefore, an intelligent integrated dust removal machine for explosion-proof environments is proposed. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention provides an intelligent integrated dust removal machine for explosion-proof locations, which solves the problem that when existing dust removal equipment uses a single valve for ash discharge, outside air may flow between the outside and inside the equipment, potentially introducing oxygen or sparks and increasing the risk of explosion.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an intelligent dust removal integrated machine for explosion-proof locations, comprising a dust collector body, and further comprising:

[0012] The ash discharge assembly includes an ash hopper fixedly installed at the bottom of the dust collector body, an ash discharge pipe fixedly installed at the bottom of the ash hopper, and a pneumatic valve one and a pneumatic valve two installed on the ash discharge pipe.

[0013] Preferably, a pressure sensor is installed on the air inlet pipe, and a pressure sensor is installed on the inner wall of the dust collector body;

[0014] When the pressure inside the air inlet duct is lower than the set value, the PLC controls the frequency converter to increase the fan speed.

[0015] Preferably, the filter cartridge backflushing assembly includes an air tank fixed to the outside of the dust collector body, and a spray pipe is connected to the outside of the air tank. The spray pipe is located inside the dust collector body and is used for cleaning the filter cartridge.

[0016] A pulse solenoid valve is installed on the nozzle.

[0017] Preferably, the fire-fighting component includes a fire-fighting nozzle fixed inside the dust collector body, a water pipe solenoid valve is installed on the fire-fighting nozzle, and an explosion-proof thermocouple probe is fixed on the inner wall of the dust collector body.

[0018] Preferably, the ash unloading assembly further includes a guide rod and a threaded rod installed at the bottom of the ash hopper. The threaded rod is movably connected to the bottom of the ash hopper, and a drive motor is installed at the bottom of the threaded rod. The drive motor is fixedly installed with the bracket.

[0019] Preferably, the bottom of the ash hopper is connected to a movable ring via a second rubber connector, and the bottom of the movable ring is connected to the top of the ash discharge pipe via a first rubber connector.

[0020] Preferably, the movable ring is fixedly fitted with two mating sleeves, one of which is threadedly fitted with the threaded rod, and the other mating sleeve slides vertically outside the guide rod;

[0021] When the pneumatic valve is opened, the movable ring stretches the rubber connector 2 and the rubber connector 1 under the action of the drive motor, so that the movable ring is sleeved on the outside of the ash discharge pipe.

[0022] Preferably, a support plate is fixedly mounted inside the movable ring by a fixing rod, the top of the support plate is frustum-shaped, and a guide rod is fixedly mounted at the bottom of the support plate;

[0023] When the pneumatic valve is opened, the guide rod moves downwards inside the ash discharge pipe following the movable ring.

[0024] Preferably, an elastic guide is fixedly installed inside the dust collector body and at the bottom of the filter cartridge, a connecting member is fixedly installed in the middle of the elastic guide, and the bottom of the connecting member is connected to the support plate through a connecting rod.

[0025] Preferably, a spring telescopic rod is fixedly mounted on the outside of the docking member, and a scraper is fixedly mounted on the output end of the spring telescopic rod, the scraper abutting against the inner wall of the ash hopper.

[0026] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0027] This invention involves starting a fan to allow dusty gas to enter the dust collector body through the inlet pipe. The dust is blocked by a filter cartridge and falls into the ash hopper for storage. An explosion-proof rotary paddle level gauge installed in the ash discharge assembly detects the volume of accumulated dust. When the level reaches a preset height, the ash discharge procedure is initiated through a two-stage pneumatic valve. Pneumatic valve one and pneumatic valve two open and close alternately. During ash discharge, pneumatic valve one is open and pneumatic valve two is closed, and the dust is temporarily stored in the middle cavity of the ash discharge pipe. After pneumatic valve one closes, pneumatic valve two opens, and the dust is discharged into a sealed container. This process isolates the inside of the equipment from the outside air during ash discharge, preventing oxygen from entering or dust from leaking out, and reducing the risk of explosion.

[0028] This invention monitors the negative pressure of the air inlet pipe in real time by installing a pressure sensor inside the air inlet pipe. When the pressure is lower than the set value, the PLC controls the frequency converter to increase the fan speed to ensure the dust collection effect. A pressure sensor is installed inside the dust collector body. When the filter cartridge resistance increases and the internal pressure exceeds the standard, the fan frequency is automatically increased to increase the exhaust volume and reduce the resistance, thereby achieving the purpose of reducing energy consumption.

[0029] This invention installs a compressed air backflushing device on the filter cartridge. The backflushing is triggered by a PLC controller at regular intervals or by differential pressure, which blows the dust on the surface of the filter cartridge into the dust hopper, thus avoiding filter cartridge clogging, extending service life, and reducing the frequency of manual cleaning.

[0030] This invention installs an explosion-proof thermocouple probe at the upper part of the dust collector body to monitor the temperature in real time. When the temperature reaches a set threshold, it triggers an audible and visual alarm and links the fire-fighting components. When the explosion-proof thermocouple probe detects overheating, the PLC controls the water pipe solenoid valve to open and spray water through the fire sprinkler to cool down the dust and suppress dust dispersion.

[0031] This invention collects dust from the filter cartridge inside the ash hopper. When the pneumatic valve is opened, the drive motor rotates the threaded rod, and the movable ring moves downward under the action of the connecting sleeve. The movable ring gradually moves down and fits onto the outside of the ash discharge pipe. During the downward movement, the rubber connector 2 and the rubber connector 1 are stretched, thereby increasing the volume at the bottom of the ash hopper. At the same time, the movement of the movable ring improves the flow of dust inside, preventing dust accumulation. The guide rod, through the support plate and the fixed rod, follows the movable ring downward in the ash discharge pipe, preventing dust accumulation due to the space limitation of the ash discharge pipe.

[0032] This invention utilizes the downward movement of the movable ring to drive the docking part to pull the middle of the elastic guide downward. Since the elastic guide is made of elastic material, the curvature of the top of the elastic guide gradually increases, thereby improving the efficiency of dust entering the ash hopper. At the same time, by setting the elastic guide, the dust collected in the ash hopper is separated, preventing gas from entering the dust collector body through the air inlet pipe and blowing the dust collected in the ash hopper, thereby improving the filtration effect of the filter cartridge on dusty gas.

[0042] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0043] like Figures 1 to 8 As shown, the present invention provides an intelligent dust removal integrated machine for explosion-proof locations, including a dust collector body 1, and further comprising:

[0044] Separation component 5 is disposed on the dust collector body 1;

[0045] Ash discharge assembly 2 is installed at the bottom of the dust collector body 1;

[0046] Explosion-proof rotary level gauge 4 is installed inside the ash discharge assembly 2;

[0047] Filter cartridge back-flushing assembly 6 is installed on the dust collector body 1;

[0048] Firefighting component 7 is installed inside the dust collector body 1;

[0049] The separation component 5 includes an air inlet pipe 52 connected to the inside of the dust collector body 1, a filter cartridge 53 is installed inside the dust collector body 1, and a control box 54 is fixedly installed outside the dust collector body 1.

[0050] The ash discharge assembly 2 includes an ash hopper 21 fixedly installed at the bottom of the dust collector body 1. An ash discharge pipe 22 is fixedly installed at the bottom of the ash hopper 21. A pneumatic valve 23 and a pneumatic valve 24 are installed on the ash discharge pipe 22.

[0051] By starting the fan, dusty gas enters the dust collector body 1 through the inlet pipe 52. The dust is blocked by the filter cartridge 53 and falls into the ash hopper 21 for storage. The explosion-proof rotary paddle level gauge 4 installed in the ash unloading assembly 2 detects the volume of dust accumulation. When the level reaches the preset height, the ash unloading program is started, and the ash is unloaded through a two-stage pneumatic valve. Pneumatic valve 1 23 and pneumatic valve 2 24 open and close alternately. During ash unloading, pneumatic valve 1 23 is open and pneumatic valve 2 24 is closed. The dust is temporarily stored in the middle cavity of the ash discharge pipe 22. After pneumatic valve 1 23 is closed, pneumatic valve 2 24 is opened, and the dust is discharged into a sealed container. This isolates the inside of the equipment from the outside air during the ash unloading process, preventing oxygen from entering or dust from leaking out, and reducing the risk of explosion.

[0052] like Figure 1 and Figure 3As shown, a pressure sensor 51 is installed on the air inlet pipe 52, and a pressure sensor 8 is installed on the inner wall of the dust collector body 1.

[0053] When the pressure inside the air inlet duct 52 is lower than the set value, the PLC controls the frequency converter to increase the fan speed.

[0054] Pressure sensor 51 pressure regulation: By installing pressure sensor 51 inside the air inlet pipe 52, the negative pressure of the air inlet pipe 52 is monitored in real time; when the pressure is lower than the set value, the PLC controls the frequency converter to increase the fan speed to ensure the dust collection effect;

[0055] Internal resistance adjustment: Pressure sensor 28 is installed inside the dust collector body 1. When the resistance of the filter cartridge 53 increases and the internal pressure exceeds the standard, the fan frequency is automatically increased and the exhaust volume is increased to reduce the resistance, thereby achieving the purpose of reducing energy consumption.

[0056] like Figure 1 As shown, the filter cartridge backflushing assembly 6 includes an air tank 63 fixed to the outside of the dust collector body 1. The air tank 63 is connected to a nozzle 62, which is located inside the dust collector body 1 for cleaning the filter cartridge 53.

[0057] A pulse solenoid valve 61 is installed on the nozzle 62.

[0058] By installing a compressed air backflushing device on the filter cartridge 53, the backflushing is triggered by the PLC controller at regular intervals or by differential pressure, and the dust on the surface of the filter cartridge 53 is blown into the dust hopper 21, thus avoiding clogging of the filter cartridge 53, extending its service life, and reducing the frequency of manual cleaning.

[0059] like Figure 1 As shown, the fire-fighting component 7 includes a fire-fighting nozzle 72 fixed inside the dust collector body 1, a water pipe solenoid valve 73 installed on the fire-fighting nozzle 72, and an explosion-proof thermocouple probe 71 fixed on the inner wall of the dust collector body 1.

[0060] An explosion-proof thermocouple probe 71 is installed at the upper end inside the dust collector body 1 to monitor the temperature in real time. When the temperature reaches a set threshold such as 80°C, an audible and visual alarm is triggered and the fire-fighting component 7 is linked. When the explosion-proof thermocouple probe 71 detects overheating, the PLC controls the water pipe solenoid valve 73 to open, and water is sprayed through the fire sprinkler pipe 72 to cool down and suppress dust dispersion.

[0061] Note that the water pipe solenoid valve 73 can switch between manual and automatic modes to ensure reliable start-up under extreme conditions.

[0062] like Figures 4-8As shown, the ash unloading assembly 2 also includes a guide rod 214 and a threaded rod 212 installed at the bottom of the ash hopper 21. The threaded rod 212 is movably connected to the bottom of the ash hopper 21. A drive motor 213 is installed at the bottom of the threaded rod 212. The drive motor 213 is fixedly installed with the bracket.

[0063] The bottom of the ash hopper 21 is connected to a movable ring 231 via a second rubber connector 234, and the bottom of the movable ring 231 is connected to the top of the ash discharge pipe 22 via a first rubber connector 232.

[0064] Two mating sleeves 211 are fixedly mounted on the outside of the movable ring 231. One mating sleeve 211 is threadedly fitted with the threaded rod 212, and the other mating sleeve 211 slides vertically on the outside of the guide rod 214.

[0065] When the pneumatic valve 23 is opened, the movable ring 231 stretches the rubber connector 234 and the rubber connector 232 under the action of the drive motor 213, so that the movable ring 231 is sleeved on the outside of the ash discharge pipe 22.

[0066] Inside the movable ring 231, a support plate 236 is fixedly mounted via a fixing rod 235. The top of the support plate 236 is frustum-shaped, and a guide rod 233 is fixedly mounted at the bottom of the support plate 236.

[0067] When the pneumatic valve 23 is opened, the guide rod 233 moves down inside the ash discharge pipe 22 following the movable ring 231.

[0068] The dust cleaned by the filter cartridge 53 is collected inside the ash hopper 21. When the pneumatic valve 23 is opened, the drive motor 213 drives the threaded rod 212 to rotate. The movable ring 231 moves down under the action of the connecting sleeve 211. The movable ring 231 gradually moves down and is fitted onto the outside of the ash discharge pipe 22. During the downward movement, the rubber connector 234 and the rubber connector 232 are stretched, thereby increasing the volume of the lower end of the ash hopper 21. At the same time, the movement of the movable ring 231 improves the flow of internal dust and avoids the accumulation of dust.

[0069] The guide rod 233 moves downward in the ash discharge pipe 22 along with the movable ring 231 via the support plate 236 and the fixed rod 235, thus preventing dust from accumulating due to the space limitation of the ash discharge pipe 22.

[0070] like Figures 4-8 As shown, an elastic guide 222 is fixedly installed inside the dust collector body 1 and at the bottom of the filter cartridge 53. A connecting piece 221 is fixedly installed in the middle of the elastic guide 222. The bottom of the connecting piece 221 is connected to the support plate 236 through a connecting rod 225.

[0071] As the movable ring 231 moves downward, it drives the docking part 221 to pull the middle part of the elastic guide 222 downward. Since the elastic guide 222 is made of elastic material, the curvature of the top of the elastic guide 222 gradually increases, thereby improving the efficiency of dust entering the ash hopper 21.

[0072] Meanwhile, by setting up the elastic guide 222 to separate the dust collected in the ash hopper 21, the gas is prevented from entering the dust collector body 1 through the air inlet pipe 52 and blowing the dust collected in the ash hopper 21, thereby improving the filtration effect of the filter cartridge 53 on the dust gas.

[0073] like Figures 4-7 As shown, a spring telescopic rod 224 is fixedly mounted on the outside of the docking part 221, and a scraper 223 is fixedly mounted on the output end of the spring telescopic rod 224. The scraper 223 abuts against the inner wall of the ash hopper 21.

[0074] As the docking part 221 moves downward, the fixed end of the spring telescopic rod 224 is fixedly connected to the docking part 221. The spring telescopic rod 224 gradually contracts, causing the scraper 223 to move downward along the inner wall of the ash hopper 21. The scraper 223 pushes the dust inside the ash hopper 21, preventing the accumulation of dust inside the ash hopper 21.

[0075] Working principle and usage process of this invention:

[0076] By starting the fan, dusty gas enters the interior of the dust collector body 1 through the air inlet pipe 52. The dust is blocked by the filter cartridge 53, and the filtered gas is discharged. The dust blocked by the filter cartridge 53 falls into the ash hopper 21 for storage. The explosion-proof rotary paddle level gauge 4 installed in the ash unloading assembly 2 detects the volume of dust accumulation. When the material level reaches the preset height, the ash unloading program is started and the ash is unloaded through a two-stage pneumatic valve. Pneumatic valve 1 23 and pneumatic valve 2 24 are switched on and off alternately. During ash unloading, pneumatic valve 1 23 is open and pneumatic valve 2 24 is closed. The dust is temporarily stored in the middle cavity of the ash discharge pipe 22. After pneumatic valve 1 23 is closed, pneumatic valve 2 24 is opened, and the dust is discharged into a sealed container. This isolates the inside of the equipment from the outside air during the ash unloading process, preventing oxygen from entering or dust from leaking out, and reducing the risk of explosion.

[0077] Meanwhile, a pressure sensor 51 is installed inside the air inlet duct 52 to monitor the negative pressure of the air inlet duct 52 in real time. When the pressure is lower than the set value, the PLC controls the frequency converter to increase the fan speed to ensure the dust collection effect. A pressure sensor 8 is installed inside the dust collector body 1. When the resistance of the filter cartridge 53 increases and the internal pressure exceeds the standard, the fan frequency is automatically increased to increase the exhaust volume and reduce the resistance, thereby achieving the purpose of reducing energy consumption.

[0078] By installing a compressed air back-blowing device on the filter cartridge 53, the back-blowing is triggered by the PLC controller at regular intervals or by the differential pressure, and the dust on the surface of the filter cartridge 53 is blown into the dust hopper 21, thus avoiding the clogging of the filter cartridge 53, extending its service life, and reducing the frequency of manual cleaning.

[0079] Dust cleaned by filter cartridge 53 is collected inside ash hopper 21. Pneumatic valve 23 is opened, and drive motor 213 drives threaded rod 212 to rotate. Movable ring 231 moves down under the action of connecting sleeve 211. Movable ring 231 gradually moves down and fits on the outside of ash discharge pipe 22. During the downward movement, rubber connector 234 and rubber connector 232 are stretched, thereby increasing the volume of the lower end of ash hopper 21. At the same time, the movement of movable ring 231 improves the flow of dust inside and avoids dust accumulation. Guide rod 233 moves down in ash discharge pipe 22 with movable ring 231 through support plate 236 and fixed rod 235, avoiding dust accumulation due to space limitation of ash discharge pipe 22.

[0080] As the movable ring 231 moves downward, it drives the docking part 221 to pull the middle part of the elastic guide 222 downward. Since the elastic guide 222 is made of elastic material, the curvature of the top of the elastic guide 222 gradually increases, thereby improving the efficiency of dust entering the ash hopper 21. At the same time, by setting the elastic guide 222 to separate the dust collected in the ash hopper 21, it prevents gas from entering the dust collector body 1 through the air inlet pipe 52 and blowing the dust collected in the ash hopper 21, thereby improving the filtration effect of the filter cartridge 53 on the dust gas.

[0081] As the docking part 221 moves downward, the fixed end of the spring telescopic rod 224 is fixedly connected to the docking part 221. The spring telescopic rod 224 gradually contracts, causing the scraper 223 to move downward along the inner wall of the ash hopper 21. The scraper 223 pushes the dust inside the ash hopper 21, preventing the accumulation of dust inside the ash hopper 21.

[0082] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0083] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
