Description

Technical Field

[0001] The present invention relates to the technical field of dust concentration measurement, and more particularly to an intelligent dust concentration detection device and method. Background Art

[0002] The emergence of intelligent dust concentration detection devices is an inevitable product to meet the upgrading needs of multiple fields such as industrial production, environmental protection, and occupational health. Long-term exposure to high-concentration dust (such as PM2.5 and silica dust) can cause occupational diseases such as pneumoconiosis and lung cancer. Intelligent devices can promptly remind workers to evacuate or start dust removal equipment through threshold setting and sound and light alarm functions, thereby reducing the incidence of occupational diseases, avoiding environmental fines and production suspension losses caused by excessive dust, and reducing the frequency of manual inspections. Moreover, through dust concentration trend analysis, it can guide production parameter adjustments to achieve energy saving and consumption reduction. With the help of 3D visual maps, it can more accurately locate high-concentration areas and guide the optimization of dust removal equipment layout. Therefore, the intelligent dust concentration detection device is not only a compliance tool, but also a core equipment for reducing costs and increasing efficiency. It helps enterprises achieve a balance between safe production and sustainable development under the high pressure of environmental protection by replacing manual labor with technology, data-driven decision-making, and pre-risk management. With the advancement of the "dual carbon" goals, this device will become a standard for green transformation in the industrial field.

[0003] The intelligent dust concentration detection device generally uses appropriate means to test the dust concentration around the device. After the detection is completed, the detection data will be pre-processed. If the dust concentration exceeds the standard, the dust absorption device will be started to remove the dust. After the dust removal is completed, the device will stop and wait for the next detection.

[0004] At present, the method of detecting dust concentration by weight is to sample the air through a filter membrane and then remove the filter membrane for subsequent processing such as drying and weighing. This has to be done manually and there is a large error due to the environmental influence of weighing. In addition, because the sampling time is too long, even if the dust concentration can be measured, it cannot reflect the actual situation in real time. The dust concentration may have changed from a small to a large one, and the measured dust concentration at this time is displayed as the previous one. If measures are not taken in time to reduce the dust concentration, it may cause accidents or affect the health of operators in the dust environment. Summary of the Invention

[0036] The rotating assembly 3 includes a supporting rotating body 301, and a diaphragm plate 302 is slidably connected to the interior of the supporting rotating body 301. A first spring 304 is fixedly connected between the bottom of the diaphragm plate 302 and the supporting rotating body 301. A filter membrane 303 is clamped in the middle of the diaphragm plate 302. The measuring assembly 5 includes a light receiving plate 501, and an oblique light source 502 is fixed above the light receiving plate 501. A reflecting plate 503 is provided directly above the oblique light source 502, and the reflecting plate 503 is fixedly connected to the diaphragm plate 302.

[0037] In this embodiment, it should be specifically explained that the pulse generator 10 is connected to an external power source. When the pulse generator 10 is working, the external power source continuously transmits power to the pulse generator 10 .

[0038] The main difference between this embodiment and the prior art is that this embodiment utilizes the fluidity of the gas and the initiative of the air pump 701 to absorb a large amount of floating dust, and utilizes the weight change before and after dust absorption and the amplification of the light propagation path to achieve dust concentration measurement, specifically in the rotating component 3, the measuring component 5, and the dust collection component 7;

[0039] The above structure is the main structure of this embodiment, which solves the problem of untimely dust treatment after dust measurement. The pulser 10 is an existing structure, and the specific structure and connection method of the pulser 10 are not described in detail in this embodiment.

[0040] Reference Figure 2The rotating assembly 3 includes a supporting rotating body 301, the center of the supporting rotating body 301 is fixedly connected to a first motor 306, the outer shell of the first motor 306 is fixedly connected to a first support frame 305, the outer side of the first support frame 305 is fixedly connected to the inner wall of the main shell 101, and the blowing assembly 4 includes a driving wheel 401, the driving wheel 401 is keyed to the outer side of the supporting rotating body 301, the outer side of the driving wheel 401 is meshed with a plurality of driven wheels 402, the center key of the driven wheel 402 is connected to a rotating shaft 403, one end of the rotating shaft 403 is rotatably connected to the bottom of the first support frame 305, the bottom end of the rotating shaft 403 is keyed to a blower fan 404, the outer side of the blower fan 404 is non-contactly connected to an air supply pipe 405, the bottom end of the air supply pipe 405 is fixedly connected to an air dispersion ring 406, and the air dispersion ring 406 is located above the reflector 503.

[0041] In this embodiment, it should be specifically explained that: when the dust collection component 7 generates negative pressure, the negative pressure passes through the filter membrane 303, and the dust on the other side of the filter membrane 303 adheres to the filter membrane 303 under the action of the negative pressure. Due to the accumulation of dust on the filter membrane 303, the weight of the clamping plate 302 and the filter membrane 303 increases to a certain value, and the first spring 304 is compressed and drops to a certain distance. The clamping plate 302, the filter membrane 303 and the reflective plate 503 drop to the lowest point. When the supporting rotating body 301 rotates, the driving wheel 401 also rotates with it. The driving wheel 401 drives the driven wheel 402 to rotate, and the driven wheel 402 drives the rotating shaft 403 and the blower fan 404 to rotate. The rotation of the blower fan 404 generates air flow, and the air flows downward and rushes to the upper plate surface of the light receiving plate 501, thereby cleaning the dust on the surface of the light receiving plate 501 more cleanly, making the landing point of the reflected light more accurate, and making the final dust concentration measurement more accurate.

[0042] Reference Figure 2 and Figure 4 The washing component 6 includes a second motor 601. The outer shell of the second motor 601 is fixedly connected to the bottom inner wall of the top shell 102. The rotating shaft of the second motor 601 is fixedly connected to the active screw 602. One end of the active screw 602 is fixedly connected to the active pulley 603. The periphery of the active pulley 603 is movably connected to one end of a belt 606. The other end of the belt 606 is internally connected to a driven pulley 605. The center of the driven pulley 605 is fixedly connected to a driven screw 604. The driven screw 604 and the active screw 602 are spirally connected to a brush 608. The two ends of the active screw 602 and the driven screw 604 are rotatably connected to a second support frame 607. The bristles of the brush 608 conflict with the filter plate 9.

[0043] In this embodiment, it should be specifically explained that: when the weight of the dust accumulated on the filter plate 9 reaches a threshold value, the second motor 601 is started, and the second motor 601 drives the active screw 602 and the active pulley 603 to rotate, and the active pulley 603 drives the driven screw 604 and the driven pulley 605 to rotate synchronously through the belt 606, thereby driving the brush 608 to move downward, and then the washing assembly 6 is reversed to drive the brush 608 to move upward, so that the filter plate 9 is cleaned back and forth by the brush 608.

[0044] Reference Figure 4 The blower assembly 2 includes a blower 201, which is fixed to the inner wall of the ventilation pipe 103, and the center key of the blower 201 is connected to the rotating shaft of the induction motor 202.

[0045] In this embodiment, it should be specifically explained that the induction motor 202 selects different speeds according to the signal sent by the light receiving board 501, driving the blower 201 to have different speeds. When the blower 201 rotates, the air carrying dust enters the output end of the ventilation pipe 103, and then is filtered by the filter plate 9 and discharged from the ventilation pipe 103.

[0046] Reference Figure 5 The dust collection component 7 includes an air pump 701, which is fixedly connected to the inner wall of the main shell 101. The outer periphery of the air intake of the air pump 701 is fixedly connected to the telescopic square tube 702. The telescopic square tube 702 is telescopic, and the maximum telescopic length of the telescopic square tube 702 can completely fit on the clamping plate 302. At this time, the telescopic square tube 702 and the clamping plate 302 form a sealed space. The outermost telescopic tube of the telescopic square tube 702 is fixedly connected to a connecting plate 704. The surface of the air pump 701 is fixedly connected to an oil cylinder 703, and the piston rod of the oil cylinder 703 is fixedly connected to the connecting plate 704.

[0047] In this embodiment, it is necessary to specifically explain that: the diaphragm plate 302 rotates to face the dust suction component 7, the oil cylinder 703 is started, and the oil cylinder 703 drives the telescopic square tube 702 to extend to contact the diaphragm plate 302 through the connecting plate 704. At this time, the diaphragm plate 302 and the telescopic square tube 702 remain sealed, and one side of the filter membrane 303 is completely located in the sealed space between the diaphragm plate 302 and the telescopic square tube 702. The oil cylinder 703 is closed, and the suction function of the air pump 701 is started. At this time, negative pressure is generated in the sealed space, and the negative pressure passes through the filter membrane 303. The dust on the other side of the filter membrane 303 adheres to the filter membrane 303 under the action of the negative pressure. After the threshold time, the air pump 701 is turned off, the dust on the filter membrane 303 stops accumulating, and the oil cylinder 703 is started. The oil cylinder 703 drives the telescopic square tube 702 to retract back to its original position.

[0048] Reference Figure 6The supporting rotating body 301 includes a rotating cylinder 3011, a through circular hole 3012 is provided in the center of the rotating cylinder 3011, a T-slot 3013 is provided on the outside of the rotating cylinder 3011, and a support block 3014 is fixedly connected below the T-slot 3013. The support block 3014 is divided into a bottom plate and two vertical plates. Several first support rollers 3015 are provided between the two vertical plates of the support block 3014. The first support rollers 3015 are fixedly connected to the bottom plate and the first support rollers 3015 of the support block 3014.

[0049] In this embodiment, it should be specifically explained that the vertical plates of the support block 3014 play a guiding role for the clamping plate 302 , and the clamping plate 302 slides between the vertical plates of the support block 3014 .

[0050] Reference Figure 7 The film clamping plate 302 includes a T-shaped clamping plate 3021, the horizontal plate of the T-shaped clamping plate 3021 is provided with a film clamping frame 3022, and a plurality of second support rollers 3023 are fixedly connected to the bottom of the horizontal plate of the T-shaped clamping plate 3021. The T-shaped clamping plate 3021 is slidably connected to the T-shaped slot 3013, and the second support rollers 3023 correspond to the first support rollers 3015.

[0051] In this embodiment, it should be specifically explained that the film clamping frame 3022 is used to clamp the filter membrane 303 .

[0052] Reference Figure 8 The air diffuser ring 406 includes a ring body 4061 , a plurality of input ports 4062 are provided at the top of the ring body 4061 , and a plurality of output ports 4063 are provided at the bottom of the ring body 4061 . The input ports 4062 are fixedly and sealedly connected to the air delivery pipe 405 .

[0053] In this embodiment, it should be specifically explained that the rotation of the blower fan 404 generates air flow, and the air flows downward, rushing toward the upper surface of the light receiving plate 501 through the input port 4062 and the output port 4063, thereby cleaning the dust on the surface of the light receiving plate 501 more cleanly, making the landing point of the reflected light more accurate, and making the final dust concentration measurement more accurate.

[0054] Reference Figure 9The dust collecting assembly 8 includes a supporting slot block 801, the supporting slot block 801 is provided with an open slot, the open slot is fixedly connected to the filter plate 9, the bottom of the supporting slot block 801 is fixedly connected with a dust collecting block 802, the dust collecting block 802 is provided with a bevel, the bottom of the dust collecting block 802 is provided with a dust shield 803, the bottom of the dust collecting block 802 is provided with an upper supporting roller 804, the bottom of the upper supporting roller 804 is provided with a supporting fixed block 805, the supporting fixed block 805 is fixedly connected to the outer wall of the main shell 101, the supporting fixed block 805 is provided with an avoidance groove, and the avoidance groove of the supporting fixed block 805 A lower support roller 806 is fixedly connected to the top of the groove, and the lower support roller 806 corresponds to the upper support roller 804. A second spring 807 is connected between the lower support roller 806 and the upper support roller 804. The outer side of the second spring 807 is slidingly connected to the dust shield 803. A material receiving box 808 is provided at the bottom of the supporting fixed block 805. The material receiving box 808 is fixedly connected to the outer wall of the main shell 101. The dust shield 803 is located in the opening of the material receiving box 808. A displacement sensor 809 is fixed to the bottom of the supporting fixed block 805, and the displacement sensor 809 is facing the dust inducing block 802.

[0055] In this embodiment, it should be specifically explained that: the filter plate 9 is cleaned back and forth by the brush 608, and the dust falls to the inside of the dust collecting component 8 due to the action of gravity and the guiding action of the dust collecting block 802. Due to the obstruction of the dust shield 803, the dust will not fall onto the supporting fixed block 805. As the dust continues to fall into the collecting box 808, the weight of the filter plate 9 continues to decrease, and the total weight supported by the second spring 807 decreases. Under the rebound action of the second spring 807, the filter plate 9 begins to rise to a certain height. The rising height of the filter plate 9 is less than the previous height because cleaning generally cannot be made cleaner.

[0056] Working principle of the present invention:

[0057] The main problems solved by this embodiment are: utilizing the fluidity of the gas and the initiative of the air pump 701 to adsorb a large amount of floating dust, and utilizing the weight change before and after the adsorption of the dust and the amplification of the light propagation path to achieve more accurate measurement of the dust concentration, and utilizing the timeliness of the signal transmission of the light receiving plate 501 and the change in gas flow to achieve dust filtration and collection, thereby solving the problem of untimely dust treatment after dust measurement.

[0058] The specific steps are as follows:

[0059] First, in a dusty environment, such as in a flour workshop with a lot of dust, start the first motor 306. The rotation of the rotating shaft of the first motor 306 drives the supporting rotating body 301 and the clamping plate 302 to rotate until the clamping plate 302 on one side is rotated to face the dust collection component 7. Start the oil cylinder 703. The oil cylinder 703 drives the telescopic square tube 702 to extend to contact the clamping plate 302 through the connecting plate 704. At this time, the clamping plate 302 and the telescopic square tube 702 remain sealed, and one side of the filter membrane 303 is completely located in the sealed space between the clamping plate 302 and the telescopic square tube 702. Close the oil cylinder 703 and start the suction function of the air pump 701. At this time, negative pressure is generated in the sealed space, and the negative pressure passes through the filter membrane 303. The dust on the other side of the filter membrane 303 adheres to the filter membrane 303 under the action of the negative pressure. The threshold After a certain period of time, the air pump 701 is turned off, the dust on the filter membrane 303 stops accumulating, and the oil cylinder 703 is started. The oil cylinder 703 drives the telescopic square tube 702 to retract back to its original position. As the dust accumulates on the filter membrane 303, the weight of the clamping plate 302 and the filter membrane 303 as a whole increases to a certain value. The first spring 304 is compressed and drops to a certain distance. The clamping plate 302, the filter membrane 303 and the reflecting plate 503 drop to the lowest point. The light emitted by the oblique light source 502 is reflected by the reflecting plate 503 onto the light receiving plate 501. As the reflecting plate 503 drops, the points where the light is reflected onto the light receiving plate 501 are different. The height to which the reflecting plate 503 drops can be calculated, and thus the weight of the dust added on the filter membrane 303 can be calculated. The dust concentration can be calculated by combining the power of the air pump 701.

[0060] When the dust concentration is too high and dust needs to be cleaned in time, the light receiving board 501 sends a signal to the induction motor 202. The induction motor 202 selects different speeds according to the signal sent by the light receiving board 501, driving the blower 201 to have different speeds. When the blower 201 rotates, the air carrying dust enters the output end of the ventilation pipe 103, and then passes through the filter plate 9 and is discharged from the ventilation pipe 103.

[0061] When the induction motor 202 works for a period of time according to the dust concentration, the dust on the filter plate 9 accumulates continuously, causing the dust collecting block 802 to drop and compress the second spring 807. When the displacement sensor 809 senses that the dust collecting block 802 has dropped to a certain threshold, the second motor 601 is started, and the second motor 601 drives the active screw 602 and the active pulley 603 to rotate. The active pulley 603 drives the driven screw 604 and the driven pulley 605 to rotate synchronously through the belt 606, thereby driving the brush 608 to move downward, and then the scrubbing assembly 6 is reversed to drive the brush 608 upward. Movement, so that the filter plate 9 is cleaned back and forth by the brush 608, and the dust falls down into the interior of the dust collecting component 8 due to the action of gravity and the guiding action of the dust collecting block 802. Due to the obstruction of the dust shield 803, the dust will not fall onto the supporting fixed block 805. As the dust continues to fall into the collecting box 808, the weight of the filter plate 9 continues to decrease, and the total weight supported by the second spring 807 decreases. Under the rebound action of the second spring 807, the filter plate 9 begins to rise to a certain height. The rising height of the filter plate 9 is less than the previous height because cleaning generally cannot be made cleaner.

[0062] At the same time, the first motor 306 is started. The rotation of the first motor 306's shaft drives the supporting rotating body 301 and the clamping plate 302 to rotate until the filter membrane 303 that has not absorbed dust is rotated to face the dust collection assembly 7, and the filter membrane 303 that has absorbed dust faces the pulser 10 and the camera 11. At this time, the pulser 10 and the camera 11 are turned on. The pulser 10 intermittently emits pulses to the surface of the filter membrane 303 that has absorbed dust, causing the dust on the surface of the filter membrane 303 to fall off. At this time, the camera 11 continuously captures and analyzes the surface adsorption level of the filter membrane 303 until the surface of the filter membrane 303 meets the cleaning requirements. At this time, the pulser 10 stops emitting pulses, and the total weight of the filter membrane 303 and the clamping plate 302 decreases. The filter membrane 303 rises under the rebound force of the first spring 304, but due to incomplete cleaning, it cannot return to its previous height. When it is used again to measure the dust concentration, the height of the reflective plate 503 that has dropped is not the final height of the reflective plate 503, which does not hinder it.

[0063] When the supporting rotating body 301 rotates, the driving wheel 401 also rotates with it, and the driving wheel 401 drives the driven wheel 402 to rotate, and the driven wheel 402 drives the rotating shaft 403 and the blower fan 404 to rotate. The rotation of the blower fan 404 generates air flow, and the air flows downward and rushes to the upper plate surface of the light receiving plate 501 through the output port 4063, cleaning the dust on the surface of the light receiving plate 501 more cleanly, making the landing point of the reflected light more accurate, and making the final dust concentration measurement more accurate.
