Description

Technical Field

[0001] This invention relates to a dust treatment device, specifically a sensor-based explosion-prone dust risk monitoring and early warning device. Background Technology

[0002] In industrial production, the presence of explosive dust is like a potential "time bomb." It not only pollutes the production environment but can also trigger serious safety accidents such as explosions due to excessive concentrations, posing a significant threat to the lives of operators and the property of enterprises. Therefore, risk monitoring and timely handling of explosive dust are crucial.

[0003] Currently, some explosive dust monitoring devices exist on the market, but these devices have many limitations in practical applications. Some monitoring devices can only perform a single function of dust concentration detection and lack an effective early warning mechanism. When the dust concentration exceeds the standard, they cannot promptly remind staff to take countermeasures, resulting in risks not being detected and controlled in a timely manner.

[0004] Even if a few devices have early warning functions, most do not have dust removal capabilities. After an early warning is issued, manual or other independent equipment is still required for dust removal operations. This not only increases the complexity and time cost of the operation, but also the dust concentration may further increase while waiting for dust removal, thus increasing safety hazards.

[0005] Therefore, there is an urgent need for a device that is simple in structure, easy to move, and can integrate monitoring, early warning, and efficient dust removal to solve the above problems. Summary of the Invention

[0006] The purpose of this invention is to provide a sensor-based device for monitoring and early warning of explosive dust risks, in order to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A sensor-based explosion-prone dust risk monitoring and early warning device includes a mobile support, on which a bag filter assembly is fixedly connected. A guide wall is fixedly connected to the outside of the bag filter assembly, and several guide grooves are formed on the guide wall. Several dust collection assemblies are slidably connected to the inside of the guide grooves. The dust collection assemblies are connected to the inlet of the bag filter assembly through a hose. The mobile support is also provided with a drive assembly for driving the dust collection assemblies to slide.

[0008] As a further aspect of the present invention: the dust collection assembly includes a longitudinal screw rotatably connected to the movable bracket, the longitudinal screw being located between the guide wall and the bag dust collection assembly, a longitudinal sliding member being threadedly connected to the outer side of the longitudinal screw, a dust collection pipe being fixedly connected to the longitudinal sliding member, the dust collection pipe being slidably connected to the guide groove, and the longitudinal screw being drively connected to the drive assembly.

[0009] As a further embodiment of the present invention: a horn-shaped collection port is fixedly connected to the outer end of the dust collection pipe, and the flexible hose is connected to the inner end of the dust collection pipe.

The longitudinal screws at the end of the guide wall are interconnected, and the longitudinal screws on the side of the guide wall are interconnected.

[0011] As a further embodiment of the present invention: an inspection port is provided at the connection position between the end of the guide wall and the side, and an inspection cover plate is connected to the outside of the inspection port.

[0012] As a further embodiment of the present invention: the driving assembly includes a driving motor fixedly connected to the outside of the guide wall, a driving shaft fixedly connected to the output shaft of the driving motor, an incomplete bevel gear fixedly connected to the end of the driving shaft, a longitudinal shaft rotatably connected to the movable bracket, the longitudinal shaft being located inside the guide wall, a driven bevel gear fixedly connected to the outside of the longitudinal shaft, the incomplete bevel gear meshing with the driven bevel gear, the longitudinal shaft being connected to one of the end longitudinal screws through a one-way transmission unit, the longitudinal shaft being connected to one of the side longitudinal screws through a one-way transmission unit, and the transmission directions of the two one-way transmission units being opposite.

[0013] As a further embodiment of the present invention: the unidirectional transmission unit includes a flywheel fixedly connected to the outside of the longitudinal rotating shaft, a driving pulley fixedly connected to the outside of the flywheel, a driven pulley fixedly connected to the outside of the longitudinal screw, and the driving pulley and the driven pulley being connected by a synchronous belt drive.

[0014] As a further aspect of the present invention: a reset mechanism is provided on the outer side of the two longitudinal screws that are connected to the longitudinal rotating shaft for transmission. When the toothless part of the incomplete bevel gear engages with the driven bevel gear, the longitudinal screws are reset under the reset force of the reset mechanism.

[0015] As a further embodiment of the present invention: the reset mechanism includes two longitudinal screws fixedly connected to the outer sides of a winding wheel, and an elastic rope is connected between the winding wheels, the elastic rope being always taut.

[0016] As a further embodiment of the present invention: a monitoring sensor is fixedly connected to the outer side of the guide wall, and a moving wheel is fixedly connected to the bottom of the moving bracket.

[0017] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a simple structure and is easy to move.

[0028] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" 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 will understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0029] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0030] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3 A sensor-based explosion-prone dust risk monitoring and early warning processing device includes a mobile support 1, a bag filter assembly 2 fixedly connected to the mobile support 1, a guide wall 3 fixedly connected to the outside of the bag filter assembly 2, a plurality of guide grooves 4 opened on the guide wall 3, a plurality of dust collection assemblies 5 longitudinally slidably connected inside the guide grooves 4, the dust collection assemblies 5 being connected to the inlet of the bag filter assembly 2 through a hose, and a drive assembly 6 for driving the dust collection assemblies 5 to slide on the mobile support 1.

[0031] The mobile support 1 is moved to the area where explosive dust monitoring is required. The bag filter assembly 2 then performs dust removal, quickly eliminating airborne dust and preventing explosions. After the drive assembly 6 is activated, it causes the dust collection assembly 5 to slide up and down, thus changing its suction position and allowing for faster and more thorough dust collection.

[0032] Please see Figure 4 , Figure 5 and Figure 6 The dust collection assembly 5 includes a longitudinal screw 7 rotatably connected to the movable support 1. The longitudinal screw 7 is located between the guide wall 3 and the bag filter assembly 2. A longitudinal sliding member 8 is threadedly connected to the outer side of the longitudinal screw 7. A dust collection pipe 9 is fixedly connected to the longitudinal sliding member 8. The dust collection pipe 9 is slidably connected to the guide groove 4. The longitudinal screw 7 is drively connected to the drive assembly 6. A flared collection port 10 is fixedly connected to the outer end of the dust collection pipe 9. A flexible hose is connected to the inner end of the dust collection pipe 9.

[0033] The height of the dust collection assembly 5 is adjusted by the rotation of the longitudinal screw 7. During the rotation of the longitudinal screw 7, the longitudinal sliding member 8 slides up and down. The dust collection pipe 9 provides longitudinal guidance for the device, preventing the longitudinal sliding member 8 from rotating axially. During the up and down sliding of the dust collection pipe 9, the funnel-shaped collection port 10 moves up and down, collecting dust from different locations. When the bag filter dust collector 2 is in operation, the dust is collected from the funnel-shaped collection port 10 after passing through the hose and the dust collection pipe 9.

[0034] The longitudinal screws 7 are divided into two groups. One group of longitudinal screws 7 is distributed at the end of the guide wall 3, and the other group of longitudinal screws 7 is distributed on the side of the guide wall 3. The longitudinal screws 7 at the end of the guide wall 3 are connected to each other through transmission, and the longitudinal screws 7 on the side of the guide wall 3 are connected to each other through transmission.

[0035] The longitudinal screws 7 are divided into two groups, each group being interconnected through a transmission mechanism. In the illustrated configuration, this is achieved via gears sequentially driving the tops of the longitudinal screws 7. Alternatively, other synchronous linkage methods such as pulleys or sprockets can be used. When the drive assembly 6 drives one group of longitudinal screws 7, the longitudinal screws 7 on that side rotate synchronously. Figure 2 When the gear transmission is shown, the direction of rotation between adjacent longitudinal screws 7 is opposite, which causes the adjacent horn-shaped collection ports 10 to shift vertically. This process can utilize the diffusion property of dust itself to improve the dust collection efficiency.

[0036] Please see Figure 2 and Figure 4 An inspection port 11 is provided at the connection position between the end of the guide wall 3 and the side, and an inspection cover 12 is connected to the outside of the inspection port 11. The internal parts can be repaired after the inspection cover 12 is opened.

[0037] Please see Figure 4 and Figure 5The drive assembly 6 includes a drive motor 13 fixedly connected to the outside of the guide wall 3. A drive shaft 14 is fixedly connected to the output shaft of the drive motor 13. An incomplete bevel gear 15 is fixedly connected to the end of the drive shaft 14. A longitudinal shaft 16 is rotatably connected to the moving bracket 1. The longitudinal shaft 16 is located inside the guide wall 3. A driven bevel gear 17 is fixedly connected to the outside of the longitudinal shaft 16. The incomplete bevel gear 15 meshes with the driven bevel gear 17. The longitudinal shaft 16 is connected to one of the end longitudinal screws 7 via a one-way transmission unit 18. The longitudinal shaft 16 is also connected to one of the side longitudinal screws 7 via a one-way transmission unit 18. The two one-way transmission units 18 have opposite transmission directions. Please refer to [link to relevant documentation]. Figure 7 The unidirectional transmission unit 18 includes a flywheel fixedly connected to the outside of the longitudinal rotating shaft 16. A driving pulley 19 is fixedly connected to the outside of the flywheel, and a driven pulley 20 is fixedly connected to the outside of the longitudinal screw 7. The driving pulley 19 and the driven pulley 20 are connected by a synchronous belt 21. The specific mechanism of the flywheel is as follows: Figure 7 As shown, this mechanism is widely used in fields such as bicycles. The specific structure will not be described. This mechanism can achieve unidirectional power transmission.

[0038] In one embodiment of this application, the drive assembly 6 drives the longitudinal shaft 16 to rotate via the one-way transmission unit 18, and drives the longitudinal screw 7 on one side to rotate via the pulley mechanism. Figure 4 and Figure 5 As shown, when the drive motor 13 rotates, the incomplete bevel gear 15 rotates. Since the transmission directions of the two one-way transmission units 18 are opposite, the drive motor 13 can only transmit power through one of the one-way transmission units 18, and then transmit power through the corresponding driving pulley 19, driven pulley 20 and synchronous belt 21. When the drive motor 13 is reversed, the other one-way transmission unit 18 transmits power, and the longitudinal screw 7 on the other side rotates to collect dust on that side.

[0039] A reset mechanism 22 is provided on the outer side of the two longitudinal screws 7 that are connected to the longitudinal rotating shaft 16. When the toothless part of the incomplete bevel gear 15 engages with the driven bevel gear 17, the longitudinal screws 7 are reset under the reset force of the reset mechanism 22. The reset mechanism 22 includes a winding wheel 23 fixedly connected to the outer side of the two longitudinal screws 7. An elastic rope 24 is connected between the winding wheels 23, and the elastic rope 24 is always in a taut state.

[0040] The reset mechanism 22 is the power source for resetting the longitudinal screw 7 when the incomplete bevel gear 15 engages with the driven bevel gear 17. Because the reset mechanism 22 accumulates reset force when the incomplete bevel gear 15 meshes with the driven bevel gear 17, driving the longitudinal screw 7 to rotate, the reset mechanism 22. When the driven bevel gear 17 engages with the toothless part of the incomplete bevel gear 15, the driven bevel gear 17 loses its driving force, and under the action of the reset mechanism 22, the rotated longitudinal screw 7 resets. Figure 4 As shown, as the longitudinal screw 7 rotates, the corresponding winding wheel 23 rotates and pulls the elastic rope 24 to wind up. When the power is lost, the longitudinal screw 7 resets as the elastic rope 24 resets. The reset mechanism 22 allows the trumpet-shaped collection port 10 to reciprocate up and down to collect dust. The reset mechanism 22 can also be achieved by setting a torsion spring on the outside of the longitudinal screw 7, and resetting the screw through the torsional force of the torsion spring.

[0041] A monitoring sensor 25 is fixedly connected to the outer side of the guide wall 3, and a moving wheel 26 is fixedly connected to the bottom of the moving bracket 1. The moving wheel 26 facilitates the movement of the device to the location where dust collection is required. The monitoring sensor 25 facilitates the monitoring of dust concentration, and then dust collection is performed when the dust concentration exceeds the standard. To further avoid dust explosion caused by equipment startup, the drive motor 13 in the device can be driven by a DC motor and enclosed in a sealed area to prevent explosion caused by electrical sparks during equipment startup.

[0042] Working principle: After the mobile support 1 moves to the explosion-prone dust monitoring area, the bag filter assembly 2 starts dust collection, quickly removing dust from the air to prevent an explosion. The drive assembly 6 then activates, causing the dust collection assembly 5 to slide up and down, improving suction speed and thoroughness.

[0043] The height of the dust collection assembly 5 is adjusted by the longitudinal screw 7. When the longitudinal screw 7 rotates, it drives the longitudinal sliding member 8 to slide up and down. The dust collection pipe 9 provides longitudinal guidance to prevent the longitudinal sliding member 8 from rotating axially. At the same time, it drives the funnel-shaped collection port 10 to move up and down to collect dust at different positions. The bag dust collector assembly 2 collects dust from the funnel-shaped collection port 10 through the hose and the dust collection pipe 9.

[0044] The longitudinal screws 7 are divided into two groups and drive each other, and can be synchronously linked by top gears, pulleys or sprockets. When gear transmission is used, the drive assembly 6 drives one group of screws to rotate, and the adjacent longitudinal screws 7 rotate in opposite directions, so that the adjacent funnel-shaped collection ports 10 are staggered vertically, which improves the collection efficiency by utilizing the dust diffusion property.

[0045] In one embodiment, the drive assembly 6 drives the longitudinal shaft 16 to rotate via the one-way transmission unit 18, and then drives the longitudinal screw 7 on one side to rotate via the pulley mechanism. When the drive motor 13 rotates, the incomplete bevel gear 15 rotates. Because the two one-way transmission units 18 have opposite transmission directions, the drive motor 13 transmits power through only one of them. When the motor rotates in reverse, the other one-way transmission unit 18 works, driving the screw on the other side to rotate and collect dust.

[0046] The reset mechanism 22 provides power for the reset of the longitudinal screw 7. When the incomplete bevel gear 15 meshes with the driven bevel gear 17, driving the screw to rotate, the reset mechanism 22 accumulates reset force; after the two disengage, the longitudinal screw 7 is reset under the action of the reset mechanism 22. Figure 4As shown, when the screw rotates, the winding wheel 23 rotates and winds up the elastic rope 24. After the power is lost, the elastic rope 24 resets and drives the longitudinal screw 7 to reset. The reset mechanism 22 can also be reset by setting a torsion spring on the outside of the longitudinal screw 7 and using torque to achieve reset.
