Description

Technical Field

[0001] The present invention relates to the technical field of monitoring and alarm devices, and in particular to a monitoring and alarm device for industrial environments with the function of preventing dust explosions. Background Art

[0002] A large amount of dust will be generated in places such as mechanical processing or grain processing. When the dust concentration inside the processing space reaches a certain concentration, dust explosion is very likely to occur. During the dust explosion, the flame will quickly ignite all the dust in the space. The reaction is rapid and highly destructive, posing a serious threat to production safety. In order to prevent dust explosions, monitoring and alarm devices are needed to monitor and alarm the dust concentration inside the processing site in real time. However, the monitoring and alarm devices on the market still have some shortcomings.

[0003] The patent document with patent publication number CN212365406U discloses a monitoring and alarm device with dust explosion prevention function, including a wall, a card block, a control gear and a cleaning brush. A pre-installed base is fixed by bolts at the bottom of the wall, and a device body is arranged below the pre-installed base. A card block is arranged inside the connecting seat, and a reset spring is sleeved on the outside of the card block. The lower shaft of the shift block is connected to a transmission gear, and a control gear is meshed on the right side of the transmission gear. A dust concentration sensor and a temperature sensor are arranged inside the device body, and an audible and visual alarm is arranged on the outside of the device body. A micro motor is arranged inside the lower end of the device body, and a cleaning brush is connected to the output end of the micro motor. It can be quickly installed and disassembled, which is convenient for disassembly and maintenance of the device at a later time.

[0004] The prior art still has the following problems:

[0005] In existing technical solutions, once the dust explosion prevention monitoring and alarm device is installed and positioned, its monitoring range is usually limited to the air dust concentration at a fixed point. This layout may cause the monitoring data to reflect only the dust level in a local area, rather than the true situation of the entire environment. If the dust concentration in the air near the monitoring point rises abnormally, while the dust concentration in other areas is relatively low, the system may mistakenly record and trigger an alarm, resulting in a misjudgment. In this case, although the dust concentration in the overall environment has not reached a dangerous level, an alarm may still be issued due to the limitations of the monitoring data.

[0006] In order to solve the above problems, it is necessary to design a new type of dust explosion prevention monitoring and alarm device for industrial environments. Summary of the invention

[0025] 3. With the cooperation of the ash collecting component and the lifting component in the ash collecting unit, the vertical threaded rod is driven to rotate by rotating the turning handle, and the lifting block is driven to slide on the adjusting frame and move downward by the rotation of the vertical threaded rod.

[0039] The detection suction component 51 includes a dust concentration sensor 511, which is fixedly connected to the detection channel 2. A lower mounting chamber 512 and an upper mounting chamber 513 are provided in the shell 1. A motor 514 is fixedly connected to the lower mounting chamber 512.

A driven bevel gear 519 is fixedly connected, and the driven bevel gear 519 is meshed with the driving bevel gear 517. The other end of the horizontal drive shaft 518 extends out of the vertical cylinder 516 and is fixedly connected to the fan blade 5110. An alarm 5111 and a controller 5112 are fixedly connected in the upper mounting cavity 513. The dust concentration sensor 511 and the motor 514 are electrically connected to the controller 5112 through wires. The controller 5112 is electrically connected to the alarm 5111 through wires. The controller 5112 is connected to the external switch wire, and the entire device is powered on by starting the external switch.

[0040] Specifically, the vertical drive shaft 515 is driven to rotate by the motor 514, and the vertical drive shaft 515 drives the active bevel gear 517 to rotate. The active bevel gear 517 drives the driven bevel gear 519 to rotate the horizontal drive shaft 518, thereby driving the fan blades 5110 to rotate. The fan blades 5110 rotate so that the external air is drawn into the air intake pipe 535, and enters the detection channel 2 through the air intake pipe 535, and finally enters the exhaust pipe 4. The air is discharged from the outlet end of the exhaust pipe 4. The dust concentration in the air entering the detection channel 2 is monitored by the dust concentration sensor 511. When the dust concentration in the air exceeds the set safety threshold, the controller 5112 activates the alarm 5111 to sound an alarm to remind the management personnel.

[0041] Reference Figure 1-6 The rotating component 52 includes a transmission vertical shaft 521, which is rotatably connected in the shell 1. The bottom end of the transmission vertical shaft 521 extends out of the shell 1. The top end of the transmission vertical shaft 521 extends into the lower mounting cavity 512 and is fixedly connected with a gear 1 522. A gear 2 523 is fixedly sleeved on the top end of the vertical driving shaft 515. The gear 2 523 is meshed with the gear 1 522. The diameter of the gear 2 523 is smaller than the diameter of the gear 1 522.

[0042] Specifically, the vertical driving shaft 515 rotates and drives the second gear 523 to rotate, and the second gear 523 drives the first gear 522 to make the transmission vertical shaft 521 rotate synchronously.

[0043] Reference Figure 1-6The intermittent adjustment component 53 includes a driving disk 531, which is fixedly connected to the bottom end of the vertical driving shaft 515. The driving disk 531 is provided with an avoidance opening 532 and an outer arc surface 533. The driving disk 531 is fixedly connected with a driving column 534. The bottom end of the L-shaped tube 3 is rotatably connected with an air intake pipe 535. The air intake pipe 535 is fixedly sleeved with an intermittent turntable 536. The intermittent turntable 536 is provided with a plurality of receiving grooves 537 along a circumferential array. A concave arc surface 538 is provided between two adjacent receiving grooves 537. The concave arc surface 538 is correspondingly arranged and matched with the outer arc surface 533. The driving column 534 is correspondingly arranged with the receiving groove 537.

[0044] When the drive column 534 corresponds to one of the receiving grooves 537 and enters into the receiving grooves 537, the drive column 534 will drive the intermittent rotating disk 536 to rotate once. When the drive column 534 moves out of the receiving grooves 537, the outer arc surface 533 fits with one of the concave arc surfaces 538. Therefore, when the drive disk 531 rotates one end each time, the drive column 534 is used to drive the intermittent rotating disk 536 to rotate once, and the rotation of the intermittent rotating disk 536 drives the intake pipe 535 to rotate once, so that the intake end of the intake pipe 535 can perform intermittent circular motion, so that the intake end of the intake pipe 535 corresponds to a different position each time it rotates, so that air at different positions enters into the intake pipe 535.

[0045] Embodiment 2:

[0046] Reference Figure 1-7 , which is the second embodiment of the present invention. This embodiment is different from the first embodiment in that: the cleaning and dust removal unit 6 includes a filtering and cleaning component 61, and a collecting component 62 is arranged on the filtering and cleaning component 61; the filtering and cleaning component 61 includes a dustproof filter plate 611, and the dustproof filter plate 611 is fixedly connected to the air outlet end of the exhaust pipe 4, and a vertical fixing rod 612 is fixedly connected to the inner wall of the exhaust pipe 4, and a cleaning horizontal shaft 613 is rotatably connected to the vertical fixing rod 612, and a cleaning brush 614 is fixedly connected to one end of the cleaning horizontal shaft 613, and the cleaning brush 614 is attached to one side of the dustproof filter plate 611 located on the inner side of the exhaust pipe 4, and a transmission bevel gear 1 615 is fixedly connected to the other end of the cleaning horizontal shaft 613, and a transmission bevel gear 2 616 is fixedly sleeved on the transmission vertical shaft 521, and the transmission bevel gear 2 616 is meshed with the transmission bevel gear 1 615.

[0047] Specifically, the transmission vertical shaft 521 rotates to drive the transmission bevel gear 2 616 to rotate, and the transmission bevel gear 2 616 drives the transmission bevel gear 1 615 to make the cleaning horizontal shaft 613 rotate synchronously, and the cleaning horizontal shaft 613 drives the cleaning brush 614 to rotate, so that the dust adhering to the dust filter plate 611 is brushed off by the rotation of the cleaning brush 614.

[0048] Reference Figure 1-8 The collecting component 62 includes an ash collecting port 621, which is longitudinally penetrated and opened in the lower part of the exhaust pipe 4. A collecting pipe 622 connected to the ash collecting port 621 is fixedly connected to the outer pipe wall of the exhaust pipe 4. A collecting cylinder 623 is arranged in the collecting pipe 622. A mounting rod 624 is fixedly connected to the cleaning horizontal axis 613, and a cleaning scraper 625 is fixedly connected to the mounting rod 624.

[0049] Specifically, the cleaning horizontal axis 613 is rotated to drive the mounting rod 624 to rotate the cleaning scraper 625, and the cleaning scraper 625 scrapes the brushed dust off to the ash collecting port 621, so that the fallen dust enters the collection pipe 622 through the ash collecting port 621, and finally falls into the collection barrel 623 for collection; the rest of the structure is the same as that of Example 1.

[0050] Embodiment 3:

[0051] Reference Figure 1-9 , which is the third embodiment of the present invention. This embodiment is different from the second embodiment in that: the ash taking unit 7 includes an ash taking component 71, which is arranged on the collecting component 62, and is provided with a lifting component 72; the ash taking component 71 includes a lower cover 711, and the lower cover 711 is movably sleeved on the bottom end of the collecting pipe 622, and the lower part of the tube wall of the collecting pipe 622 is fixedly connected with an adjusting frame 712, and a lifting block 713 is slidably connected to the adjusting frame 712, and the lifting block 713 is fixedly connected to the cover wall of the lower cover 711.

[0052] Specifically, the lifting and lowering of the lifting block 713 can drive the lower cover 711 to lift and lower synchronously, thereby moving the collecting cylinder 623, so that the height position of the collecting cylinder 623 can be adjusted, so that the collecting cylinder 623 can be adjusted to the bottom of the collecting tube 622 to facilitate the removal of the collecting cylinder 623.

[0053] Reference Figure 1-9 The lifting component 72 includes a vertical threaded rod 721 , which is rotatably connected to the adjustment frame 712 , and a rotating handle 722 is fixedly connected to the bottom end of the vertical threaded rod 721 .

[0054] Specifically, the vertical threaded rod 721 is driven to rotate by rotating the handle 722. Under the thread cooperation between the vertical threaded rod 721 and the lifting block 713, the vertical threaded rod 721 rotates to drive the lifting block 713 to slide on the adjustment frame 712 and move downward; the rest of the structure is the same as that of Example 2.

[0055] Reference Figure 1-9 The working principle of the monitoring and alarm device for preventing dust explosion in industrial environment of the present invention is as follows:

[0056] When in use, the shell 1 is fixed by bolts in the area to be monitored. When dust monitoring is carried out in the industrial environment area, the motor 514 is started, and the vertical drive shaft 515 is driven to rotate by the motor 514, and the vertical drive shaft 515 drives the active bevel gear 517 to rotate, and the active bevel gear 517 drives the driven bevel gear 519 to rotate the horizontal drive shaft 518, thereby driving the fan blades 5110 to rotate. The fan blades 5110 rotate so that the external air is drawn into the air inlet pipe 535, and enters the detection channel 2 through the air inlet pipe 535, and finally enters the exhaust pipe 4. After the dust in the air is filtered by the dust filter plate 611, the air is discharged from the outlet end of the exhaust pipe 4.

[0057] When the vertical driving shaft 515 rotates, it drives the second gear 523 to rotate, and the second gear 523 drives the first gear 522 to rotate the transmission vertical shaft 521, and the transmission vertical shaft 521 drives the driving disk 531 to rotate synchronously, and the driving disk 531 drives the driving column 534 to rotate synchronously, and the avoidance opening 532 is used to avoid the intermittent rotating disk 536 to avoid blocking the rotation of the intermittent rotating disk 536. When the driving column 534 corresponds to one of the receiving and shifting grooves 537 and enters the receiving and shifting grooves 537, the driving column 534 will drive the intermittent rotating disk 536 to rotate once. When the driving column 534 moves out of the receiving and shifting grooves 537, the outer arc surface 533 fits with one of the concave arc surfaces 538, so that when the driving disk 531 rotates one end, the driving column 534 is used to shift the intermittent rotating disk 536 to rotate once. The intermittent turntable 536 rotates to drive the air intake pipe 535 to rotate once, so that the air intake end of the air intake pipe 535 can perform intermittent circular motion, so that the air intake end of the air intake pipe 535 corresponds to a different position each time it rotates, so that air at different positions enters the air intake pipe 535, so that the dust concentration sensor 511 in the detection channel 2 can monitor the dust concentration at different positions at regular intervals, and the dust concentration in multiple different areas can be monitored to make the monitoring data more accurate. When the dust concentration sensor 511 detects that the dust concentration is too high and may easily lead to a dust explosion, the controller 5112 activates the alarm 5111 to sound an alarm, thereby reminding the management personnel to deal with it in time to prevent the occurrence of dust explosion.

[0058] In addition, when the transmission vertical shaft 521 rotates, it drives the transmission bevel gear 2 616 to rotate, and the transmission bevel gear 2 616 drives the transmission bevel gear 1 615 to make the cleaning horizontal shaft 613 rotate synchronously. The cleaning horizontal shaft 613 drives the cleaning brush 614 to rotate, so that the dust adhering to the dust filter plate 611 is brushed off by the rotation of the cleaning brush 614. At the same time, the cleaning horizontal shaft 613 drives the mounting rod 624 to rotate the cleaning scraper 625, and the dust brushed off is scraped off by the cleaning scraper 625 to the ash collecting port 621, so that the fallen dust enters the collection pipe 622 through the ash collecting port 621, and finally falls into the collection barrel 623 for collection, thereby preventing the entered dust from entering the industrial environment again to cause pollution.

[0059] When the dust in the collecting barrel 623 needs to be cleaned, the vertical threaded rod 721 is driven to rotate by rotating the turning handle 722, and the lifting block 713 is driven to slide on the adjusting frame 712 and move downward by the rotation of the vertical threaded rod 721, and the lifting block 713 drives the lower cover 711 to move downward synchronously, thereby causing the collecting barrel 623 to move downward until the collecting barrel 623 moves to the bottom of the collecting tube 622, and then the management personnel removes the collecting barrel 623 from the lower cover 711, and then pours out the dust collected in the collecting barrel 623, thereby completing the cleaning of the dust in the collecting barrel 623.

[0060] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
