[0002] With the rapid development of new energy technologies in my country, lithium batteries, solar energy, and related automation industries are receiving increasing attention. Consequently, dust generated during various production processes, such as carbon black from raw materials, and dust produced during die-cutting, grinding, and welding of non-ferrous metals, is difficult to handle. This is because the new energy industry is highly automated, and equipment components frequently change positions due to variations in product processes. Furthermore, the generated non-ferrous metal dust has small particle sizes, is difficult to collect, and is flammable and explosive. Therefore, the requirements for dust collection equipment are particularly high, including portability (suitable for use in factory freight elevators), functional integration, and explosion-proof performance. Currently, there are relatively few dust collection devices on the market that simultaneously meet these explosion-proof requirements.

Detailed Implementation

[0028] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0029] It should be noted that in the description of this utility model, the terms "upper", "lower", "left", "right", "inner", "outer", etc., indicating the direction or positional relationship are based on the direction or positional relationship shown in the drawings. This is only for the convenience of description and does not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0030] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0031] like Figures 1 to 8As shown, an explosion-proof cartridge dust collector includes a movable housing 100. Heavy-duty casters 19 are installed at the bottom of the housing 100, enabling the dust collector to move. The housing 100 contains a cartridge chamber 101, an air reservoir chamber 102, a fan chamber 103, and a filter chamber 104, which are connected sequentially. Filter cartridges are installed in the cartridge chamber 101, and an air inlet hood 14 is installed on the outside of the cartridge chamber 101. A pulse jet cleaning device is installed in the air reservoir chamber 102. A fan 10, specifically an explosion-proof fan, is installed in the fan chamber 103. A filter, which can be a high-efficiency filter or an activated carbon filter, is installed in the filter chamber 104. A filter frame 13 is installed in the filter chamber 104, and the filter is mounted on the filter frame 13. An air outlet plate 27 is installed at the top of the filter chamber 104, and a high-efficiency inspection door 22 is installed on the side of the filter chamber 104 for convenient filter maintenance. As can be seen, this utility model adopts an integrated structured design for filtration and dust removal, which reduces the floor space and has a reasonable dust collection fluid layout.

[0032] The explosion-proof cartridge dust collector of this utility model also includes a parameter detection unit, which is electrically connected to the fan 10 and the pulse soot blowing device respectively. The parameter detection unit is used to detect the operating parameters of the dust collector and control the fan 10 and the pulse soot blowing device according to the operating parameters. The operating parameters may include the temperature inside the shell 100, the air velocity of the air inlet hood 14, the pressure difference between the surface and the inside of the filter cartridge, etc.

[0033] This invention is applicable to the control of explosive dust environments in industries such as lithium batteries, pharmaceuticals, carbon black, food, and electronics. In actual use, the parameter detection unit can monitor the operating parameters of the dust collector in real time and control the operation of the fan 10, pulse blowing device, etc., according to the operating parameters to promptly remove dust from the filter cartridge surface and handle abnormal temperatures in a timely manner, thus improving explosion-proof performance. Simultaneously, by monitoring the inlet air velocity in real time, it can promptly clean any blockages at the air inlet, ensuring reliable operation of this invention. It achieves automatic monitoring, reduces labor, and lowers costs.

[0034] like Figures 1 to 8 As shown, the dust collector also includes a dust collection device, which includes a funnel 15, a mobile dust collection trolley 17, and a discharge valve located between the funnel 15 and the mobile dust collection trolley 17; and / or; the mobile dust collection trolley 17 is provided with a viewing window 171; the bottom of the mobile dust collection trolley 17 is provided with wheels 170. In actual use, the amount of dust collected can be easily observed through the viewing window 171 on the mobile dust collection trolley 17 for timely cleaning. Because the bottom of the mobile dust collection trolley 17 is provided with wheels 170, it can be moved easily, simplifying cleaning.

[0035] like Figure 3 , Figure 4 and Figure 9 As shown, the unloading valve is a simple manual pull-out valve 16. The manual pull-out valve 16 includes a top connecting plate 165, a middle guide plate assembly, a bottom connecting plate assembly, and a pull-out plate 164 provided on the middle guide plate. The pull-out plate 164 moves within the middle guide plate assembly, and the top connecting plate 165, the middle guide plate assembly, and the bottom connecting plate assembly are all annular. The top connecting plate 165 is connected to the bottom port of the funnel 15. The bottom connecting plate assembly is detachably connected to the top of the mobile ash storage trolley 17. A limit component is provided on the middle guide plate assembly to limit the pull-out plate 164. A sealing structure is provided between the bottom connecting plate assembly and the middle guide plate assembly.

[0036] like Figure 9 As shown, in this embodiment, the top connecting plate 165, the middle guide plate assembly, and the bottom connecting plate assembly can be fixed together by fasteners such as screws, nuts, bolts, and rivets. The middle guide plate assembly includes two guide plates, one above the other. The front ends of the two guide plates are respectively connected to the front connecting plate 166 to form a U-shaped guide plate 163. The front connecting plate 166 has an opening, and the pull plate 164 moves in and out of the U-shaped guide plate 163 through the opening to realize the opening and closing of the manual pull plate valve 16.

[0037] The sealing structure consists of a sealing felt 162, which possesses certain sealing performance and elasticity. Due to the compression effect of the sealing felt 162, the manual pull-out valve 164 achieves a sealing function on both its upper and lower surfaces. Simultaneously, the limiting assembly includes multiple limiting bolts 169, all positioned around the U-shaped guide plate 163 to limit the pull-out plate 164 and ensure its reliable operation.

[0038] like Figure 9 As shown, in this embodiment, the bottom connecting plate assembly includes a bottom plate 161 and a pull-out valve connecting section 167 located at the bottom of the bottom plate 161. The pull-out valve connecting section 167 covers the top of the mobile ash storage trolley 17 and is detachably connected via a latching tongue plate 1610.

[0039] When the user observes through the visualization window 171 that the dust inside the mobile ash storage trolley 17 has reached a certain height, it indicates that manual cleaning is required. First, close the simple manual pull-out valve 16. Simply push its pull plate 164 to the bottom, and the limit bolt 169 will naturally stop, preventing further dust from falling from the mobile ash storage trolley 17 and the funnel 15. Open the latch tongue 1610 to disengage the mobile ash storage trolley 17 from the manual pull-out valve 16. After cleaning, the mobile ash storage trolley 17 will return to its original position. Then, reopen the pull plate 164 of the simple manual pull-out valve 16.

[0040] like Figures 1 to 8As shown in the figure, the explosion-proof cartridge dust collector of this utility model also includes an alarm unit, which is electrically connected to the parameter detection unit. In this embodiment, the alarm unit includes an explosion-proof tri-color light 24, which is located on the outside of the housing 100. Of course, the alarm unit is not limited to the explosion-proof tri-color light 24 listed above, and may also use a speaker, etc.

[0041] The explosion-proof cartridge dust collector of this utility model also includes an electrical control box 6, which is installed in the filter chamber 104. The filter chamber 104 is also equipped with an access door 21 for the electrical control box 6, facilitating its maintenance. The electrical control box 6 contains a control unit, which is electrically connected to a parameter detection unit and an alarm unit. In a preferred embodiment, the electrical control box 6 includes a communication unit, which is electrically connected to the control unit and used for communication with a remote control center.

[0042] In this embodiment, an explosion-proof junction box 8 is provided on the top of the housing 100. The explosion-proof junction box 8 is electrically connected to the electrical control box 6. An explosion-proof cable clamping and sealing joint 23 is provided on the explosion-proof junction box 8. Wiring is performed through the explosion-proof cable clamping and sealing joint 23, which improves the explosion-proof performance.

[0043] like Figures 1 to 8 As shown, the parameter detection unit includes a temperature transmitter 9, a differential pressure transmitter 7, and / or an air velocity transmitter 5. In this embodiment, the temperature transmitter 9 is an explosion-proof temperature transmitter, the differential pressure transmitter 7 is an explosion-proof differential pressure transmitter, and the air velocity transmitter 5 is an explosion-proof air velocity transmitter, thus improving the explosion-proof performance of this invention.

[0044] Temperature transmitter 9 is used to detect the temperature inside housing 100. When an abnormal temperature change occurs inside housing 100, the control unit triggers the alarm unit, which controls the explosion-proof tri-color light 24 to illuminate to alert the user. Of course, the control unit can also shut down the system, activate fire alarms, etc., based on the temperature value, and can also upload data to a remote control center via the communication unit to prevent the fault from escalating.

[0045] The differential pressure transmitter 7 is used to detect the pressure difference between the inside and the surface of the filter cartridge, and can also display the pressure difference. When the pressure difference reaches the preset pressure limit, it transmits the corresponding signal to the control unit or the pulse blowing device, which then starts the pulse blowing device to blow away dust, thereby preventing excessive dust on the surface of the filter cartridge.

[0046] The wind speed transmitter 5 is used to detect the air intake speed of the air intake hood 14. When the air intake speed is abnormal, the control unit can notify the user to clean the air intake of the air intake hood in time.

[0047] like Figures 1 to 8As shown in the figure, the pulse soot blowing device in this embodiment includes an air tank 26, an air outlet pipe connected to the air tank 26, an explosion-proof solenoid valve 11 installed on the air outlet pipe, and a lotus-shaped nozzle 12 installed on the air outlet pipe. The explosion-proof solenoid valve 11 is electrically connected to a pressure transmitter. Meanwhile, the air tank 26 is connected to an oil-water separator 18 through a pipeline. The oil-water separator 18 is located on the outside of the housing 100 and is used to regulate the compressed air pressure and separate oil and water in the compressed air.

[0048] In a preferred embodiment, the pulse blowing device includes four air outlet pipes, each of which is equipped with a lotus-head nozzle 12. The four lotus-head nozzles 12 are corresponding to the four filter cartridges in the filter cartridge chamber 101. Specifically, the air outlet direction of the lotus-head nozzles 12 is arranged towards the filter cartridge chamber 101. The pressure transmitter is located on the top outer side of the housing 100.

[0049] like Figures 1 to 8 As shown, at least one filter cartridge is installed in the filter cartridge chamber 101, each filter cartridge including a nano flame-retardant filter element 2, and each filter cartridge is arranged horizontally. A filter cartridge inspection port is provided on the side of the filter cartridge chamber 101, one-to-one with each filter cartridge. A dustproof ring 4 is provided on the outside of the filter cartridge inspection port, and a filter cartridge inspection door 1 is detachably connected to the dustproof ring 4. Filter cartridges can be replaced in a bag-in / bag-out manner through the filter cartridge inspection door 1, dustproof ring 4, and filter cartridge inspection port. In a preferred embodiment, a flameless venting device 25 is provided on the top outer side of the filter cartridge chamber 101. This flameless venting device 25 improves the explosion-proof performance of the dust collector. If the differential pressure gauge of the dust collector shows a value exceeding the range and the differential pressure value does not change after backflushing, and the airflow of the dust collector is significantly weakened, it can be determined that the filter cartridge needs to be replaced. In other situations, such as dust spraying from the dust collector outlet window or increased noise from the fan 10, further assessment is needed to determine whether the filter cartridge needs to be replaced. In addition, the fan room 103 is equipped with a fan maintenance door 20, which allows for convenient maintenance of the fan 10.

[0050] like Figures 1 to 9 As shown in the figure, the specific working method of this utility model is as follows:

[0051] Under the negative pressure drive of the explosion-proof fan 10 of the dust collector, the dust-laden gas is drawn into the filter cartridge chamber 101 through the air inlet hood 14. Larger dust particles settle directly into the funnel 15 due to gravity. The remaining fine dust particles are deeply purified by the surface of the nano flame-retardant filter cartridge, and then highly filtered by the HEPA 13 / 14 high-efficiency filters inside the filter cartridge, the air bag chamber 102, and the air outlet of the explosion-proof fan chamber 103. Finally, the clean air is discharged into the atmosphere.

[0052] When dust accumulates to a certain amount on the surface of the nano flame-retardant filter cartridge, the internal pressure difference on the filter cartridge surface reaches the set value of the explosion-proof differential pressure transmitter 7, triggering the explosion-proof solenoid valve 11 of the pulse soot blowing device. The compressed air in the air tank 26 back-blown the filter cartridge, causing the dust on the filter cartridge surface to fall into the funnel 15. Users regularly use the simple manual pull-out valve 16 to clean the dust in the funnel 15 and the visual mobile ash storage trolley.

[0053] When improper operation occurs or the dust collection is not cleaned regularly as required by the instruction manual, dust will accumulate abnormally on the surface of the nano flame-retardant filter cartridge, causing the internal temperature of the equipment to rise. When the set safety value of the explosion-proof temperature transmitter 9 is reached, the explosion-proof temperature transmitter 9 will automatically issue an alarm signal, and the explosion-proof three-color light 24 will activate an audible and visual alarm. The filter cartridge itself also has flame-retardant properties, thus preventing fires or other accidents.

[0054] In special circumstances, such as a dust explosion inside the equipment, the flameless relief device 25 will come into play, releasing pressure and sending an alarm signal to the control center immediately.

[0055] As can be seen, this utility model has the following advantages: integrated whole machine design, mobile, and small footprint; all electrical components are explosion-proof certified; and equipped with a flameless explosion relief device; large-capacity ash storage bin, visible and movable, with snap-lock sealing, and can be used with a pull-out valve to realize online ash bin cleaning function, which is simple and convenient to operate; the air outlet can be equipped with a high-efficiency filter or plate activated carbon filter to increase filtration efficiency or collect odors; the equipment noise is less than 85dB, which meets the noise requirements of industrial environment; the automatic jet cleaning device can realize online, differential pressure and shutdown back-flushing functions, with significant cleaning effect; standard configuration of nano-coated antistatic filter cartridge; embedded electronic control system, good human-machine interface, simple operation and beautiful appearance; optional external remote control box; compressed air pre-pressure regulating filter, which can automatically drain water and oil.

[0056] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications or improvements to the same explosion-proof cartridge dust collector made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
