Description

Technical Field

[0001] The invention relates to the technical field of dust control, and in particular to dust detection equipment for workshop processing. Background Art

[0002] As a production site, the workshop will inevitably generate dust and diffuse in the workshop during the production and processing process. When workers work in a dusty workshop for a long time, the dust in the air can easily affect the workers' health, and even explode when the dust concentration is too high; therefore, effective dust control in the workshop is of great significance to the health of workers and the safe production of the workshop. The current dust control equipment mainly sucks air into the box and then uses the filter to filter the dust in the air. However, the filter is prone to clogging during long-term use, so it can not play a filtering role and cannot meet the actual use needs.

[0003] In order to solve the above problems, there are management equipments on the market that can clean the filter. The management equipments include a bracket and a management mechanism arranged on the bracket. The bracket is installed above the workshop. After the air in the workshop is sucked into the box through the induced draft hood, the dust in the air is adhered to the filter under the action of the filter. During the period when the filter is filtering the dust, the filter is vibrated by the vibration motor, so that the dust adhered to the filter can be cleaned up, thereby ensuring that the filter can filter the dust in the air efficiently and improving the practicability of the equipment.

[0004] The above-mentioned device has the following problems during actual use: although the equipment realizes preliminary cleaning of the dust on the filter screen through the vibration motor, the cleaned dust will fall to the bottom of the box, resulting in a large amount of dust accumulated at the bottom of the box that needs to be cleaned, but the equipment does not have a detection mechanism to detect and remind the amount of dust accumulation in the box, and thus workers need to spend more time to continuously check the amount of dust accumulation and clean the dust. The work is relatively cumbersome and brings inconvenience to the workers' work; and, if the workers forget to clean the dust in the box, as time goes by, it will cause dust to spread in the box, thereby reducing the filtering effect of the filter screen and causing inconvenience to the use of the filter screen.

[0016] The principles and advantages of this solution are:

[0017] 1. The air is discharged into the cylindrical cylinder through the air inlet of the cylindrical cylinder. During the air flow in the cylindrical cylinder, the dust mixed in the air is adsorbed by the dust removal plate, so that the dust mixed in the air can adhere to the dust removal plate; during the period when the dust adheres to the dust removal plate, the intermittent rotation of the dust removal plate, the circumferential reciprocating motion of the baffle plate, and the vertical reciprocating motion of the brush layer and the orifice plate enable the orifice plate to fully scrape the dust adhering to the dust removal plate, and the scraped dust will be at the bottom of the cylindrical cylinder. During the dust falling period, the baffle moves to a position away from the bottom hole, so that the baffle and the bottom hole are misaligned, and the dust can fall onto the collecting block under the action of the bristle layer to complete the collection of the dust; during the dust collection period, as the weight of the dust continues to increase, the weight of the dust accumulation will become heavier and heavier, until the weight of the dust accumulation reaches a certain value, thereby driving the collecting block to move vertically downward, triggering the alarm to sound, reminding the workers that the dust accumulated in the box needs to be cleaned.

[0018] 2. The filter is set up to further filter the air discharged along the circular hole, so that the amount of dust contained in the air is reduced again, that is, the air is purified, ensuring that when the air is discharged, it does not pollute the environment of the workshop and does not harm the human body.

[0019] 3. The first electrode ball and the second electrode ball are provided so that only when the weight of the dust accumulation in the collection block reaches a specified value, the collection block will move to a specified position, so that the first electrode ball contacts the second electrode ball, triggering the alarm to realize power-on operation and sound an alarm, so as to remind the workers that the weight of the dust accumulation in the collection block has reached a maximum value, thereby facilitating the workers to clean the dust in the collection block in time; and, through the above process, it is ensured that the alarm will be triggered to sound only when the collection block collects a certain amount of dust, thereby ensuring the accuracy of the alarm, that is, the alarm will not give false alarms.

[0020] 4. When the baffle is driven by the arc-shaped rack to make circumferential reciprocating motion, the impact block can intermittently impact the copper plate, thereby making the copper plate make a sound; the sound intermittently transmitted by the copper plate can give an early warning of the operation of the entire device; when the sound is emitted intermittently, it can remind the workers that the drive shaft is rotating normally, thereby ensuring the normal operation of all structures of the cylindrical barrel, that is, the dust collection work in the air, air filtration, dust accumulation weight detection, etc. are all carried out efficiently; and if the sound of the copper plate is no longer emitted, it means that the drive shaft of the equipment has stopped rotating, so that the dust collection work, air filtration, and dust accumulation weight detection are no longer carried out, and workers are required to inspect and repair the equipment in time to ensure that the equipment can work efficiently again.

[0021] 5. The baffle makes reciprocating motion along the circumferential direction of the dust removal plate, ensuring that the baffle will be misaligned with the bottom hole only when the bristle layer makes vertical downward movement, so that the dust can fall onto the collecting block. While the baffle seals the bottom hole, air will not flow into the collecting box, so that the dust accumulated on the collecting block will not form dust under the action of air, thereby ensuring that the dust accumulated on the collecting block will not be disturbed, that is, when the weight of the dust accumulation reaches a certain value, it can trigger the alarm to sound an alarm.

[0022] 6. By adhering the dust in the air to the dust removal plate, and then scraping and collecting the dust on the dust removal plate, on the one hand, the amount of dust in the air is reduced, so that when the air is discharged along the air outlet of the cylindrical tube, the air can reduce the pollution to the environment and the harm to the human body. On the other hand, by accumulating dust on the collection block to trigger the alarm to alarm, it is ensured that dust will not accumulate on the alarm, that is, the alarm will not be disturbed by the dust, ensuring that the alarm can always be in an efficient working state; and after the collection block drives the first electrode ball to contact the second electrode ball, the worker can disassemble and remove the collection block from the material taking port of the hollow seat while the alarm continues to alarm, and then clean up the dust on the collection block, so that the collection block is reset under the action of the first spring, and prepare for the dust control in the workshop again.

[0023] 7. Driven by the horizontal block, the cleaning block can further clean the dust adhering to the dust removal plate, so that the dust adhering to the dust removal plate can be cleaned more completely and fully, thereby enhancing the cleaning effect of the dust on the dust removal plate and improving the cleaning efficiency of the dust on the dust removal plate. Finally, the dust adhering to the dust removal plate can all fall to the bottom of the cylindrical barrel, making it easier for the brush layer to push the dust onto the collecting block to complete the collection of the dust.

[0024] 8. The auxiliary block is set to push the dust scattered at the bottom of the cylindrical barrel to the position of the bottom hole, and under the action of the bristle layer, the dust scattered at the bottom of the cylindrical barrel can also fall on the collecting block to complete the collection of the dust, thereby improving the efficiency of dust collection and ensuring that the dust dropped at the bottom of the collecting barrel can be collected more comprehensively and thoroughly.

[0025] 9. The auxiliary plate drives the vibration block to do reciprocating motion. During the movement of the vibration block, the vibration block can continuously impact the dust removal plate, so that the dust adhering to the dust removal plate is loosened, that is, the force of the dust adhering to the dust removal plate is weakened; after the adhesion of the dust is weakened, the orifice plate and the cleaning block can better scrape off the dust adhering to the dust removal plate, further ensuring that the dust on the dust removal plate can be cleaned more thoroughly, thereby facilitating the collection of dust by the collection block.

[0026] 10. During the intermittent rotation of the dust removal plate, the push block moves synchronously driven by the auxiliary plate; during the movement of the push block, when the push block abuts against the disc, the disc no longer seals the circular hole under the action of the push block, and the air can be discharged along the circular hole. When the push block no longer abuts against the disc, the disc seals the circular hole again, so that the air cannot be discharged along the circular hole. Through the above movement, on the one hand, the air flowing in the cylindrical barrel can automatically discharge along the disc after the dust mixed in the air adheres to the dust removal plate, without manual operation, thus saving unnecessary troubles for the workers at work. On the other hand, since the disc is intermittently misaligned with the circular hole, the air can stay in the cylindrical barrel longer and contact the dust removal plate longer, ensuring that all the dust in the air can adhere to the dust removal plate, thereby enhancing the cleaning effect of the dust in the air.

[0051] The specific implementation process is as follows:

[0052] Start the air pump 3, and discharge the air in the workshop along the hood 4 into the cylindrical barrel 2 through the air pump 3. While the air is flowing in the cylindrical barrel 2, the dust mixed in the air is adsorbed by the dust removal plate 6, so that the dust mixed in the air can adhere to the dust removal plate 6; while the dust adheres to the dust removal plate 6, start the motor 41, and drive the drive shaft 38 to rotate through the motor 41; during the rotation of the drive shaft 38, the incomplete gear 39 rotates synchronously; during the rotation of the incomplete gear 39, when the incomplete gear 39 is meshed with the third gear 40, the third gear 40 rotates, and when the incomplete gear 39 is no longer meshed with the third gear 40, the third gear 40 stops rotating; therefore, the third gear 40 can rotate intermittently; during the intermittent rotation of the third gear 40, the rotating shaft 5 rotates synchronously; during the rotation of the rotating shaft 5, the dust removal plate 6 rotates intermittently synchronously.

[0053] During the intermittent rotation of the dust removing plate 6, the first cam 42 can also rotate driven by the driving shaft 38; during the rotation of the first cam 42, when the raised portion of the first cam 42 abuts against the vertical block 7, the vertical block 7 moves vertically downward, and the second spring is compressed; when the raised portion of the first cam 42 no longer abuts against the vertical block 7, the vertical block 7 is reset under the action of the second spring, and the vertical block 7 moves vertically upward; therefore, the vertical block 7 can make vertical reciprocating motion; during the vertical reciprocating motion of the vertical block 7, the orifice plate 8 moves synchronously; during the movement of the orifice plate 8, the orifice plate 8 can preliminarily scrape off the dust adhering to the dust removing plate 6, so that the scraped dust will fall to the position at the bottom of the cylindrical barrel 2; and, since the dust removing plate 6 can rotate intermittently, the range of action of the orifice plate 8 is expanded, so that the dust is scraped off more fully and comprehensively.

[0054] Similarly, during the rotation of the first cam 42, the transverse block 18 can also make vertical reciprocating motion; during the movement of the transverse block 18, the cleaning block 19 is driven by the transverse block 18 so that the cleaning block 19 can further clean the dust adhered to the dust removal plate 6, thereby ensuring that the dust adhered to the dust removal plate 6 is cleaned more completely and fully, thereby enhancing the cleaning effect of the dust removal plate 6 and improving the cleaning efficiency of the dust removal plate 6, and finally making the dust adhered to the dust removal plate 6 can all fall to the bottom of the cylindrical tube 2, thereby facilitating the brush layer 9 to push the dust onto the collecting block 10 to complete the collection of the dust.

[0055] At the same time, during the rotation of the driving shaft 38, the annular rack 49 rotates synchronously; during the rotation of the annular rack 49, since the annular rack 49 is engaged with the fourth gear 48, the fourth gear 48 rotates; during the rotation of the fourth gear 48, the linkage shaft 45 rotates synchronously; during the rotation of the linkage shaft 45, the second cam 46 rotates synchronously; during the rotation of the second cam 46, when the raised portion of the second cam 46 abuts against the auxiliary plate 21, the auxiliary plate 21 moves toward the position where the dust removal plate 6 is located, and the fourth spring is stretched. When the raised portion of the second cam 46 no longer abuts against the auxiliary plate 21, the auxiliary plate 21 is reset under the action of the fourth spring, and the auxiliary plate 21 moves away from the dust removal plate 6. Therefore, the auxiliary plate 21 can reciprocate along the axial direction of the rotating shaft 5.

[0056] During the movement of the auxiliary plate 21, the vibration block 22 moves synchronously; during the movement of the vibration block 22, the vibration block 22 can continuously impact the dust removal plate 6, so that the dust adhering to the dust removal plate 6 is loosened, that is, the force of the dust adhering to the dust removal plate 6 is weakened; after the adhesion of the dust is weakened, the orifice plate 8 and the cleaning block 19 can better scrape off the dust adhering to the dust removal plate 6, further ensuring that the dust on the dust removal plate 6 can be cleaned more thoroughly, and finally the dust can fall on the collecting block 10 to complete the detection of the dust component.

[0057] During the vertical reciprocating motion of the vertical block 7, the rack 32 moves synchronously; during the vertical reciprocating motion of the rack 32, since the rack 32 is meshed with the second gear 34, the second gear 34 can rotate forward and reverse; during the rotation of the second gear 34, the rotating shaft 30 rotates synchronously; during the rotation of the rotating shaft 30, the first gear 33 rotates synchronously; during the rotation of the first gear 33, since the first gear 33 is meshed with the arc-shaped rack 31, the arc-shaped rack 31 can reciprocate along the arc length direction of the guide block 29; during the reciprocating motion of the arc-shaped rack 31, the baffle 12 moves synchronously.

[0058] By reciprocating the baffle 12 along the circumferential direction of the dust removal plate 6, it is ensured that the baffle 12 is misaligned with the bottom hole 13 only when the bristle layer 9 moves vertically downward, so that the dust can fall onto the collecting block 10. While the baffle 12 seals the bottom hole 13, air will not flow into the collecting box 11, so that the dust accumulated on the collecting block 10 will not form dust under the action of air, thereby ensuring that the dust accumulated on the collecting block 10 will not be disturbed, that is, when the weight of the dust accumulation reaches a certain value, it can trigger the alarm 16 to sound an alarm.

[0059] To summarize, through the intermittent rotation of the dust removal plate 6, the circumferential reciprocating motion of the baffle 12, the vertical reciprocating motion of the brush layer 9, and the vertical reciprocating motion of the orifice plate 8 and the cleaning block 19, the orifice plate 8 and the cleaning block 19 can fully scrape off the dust adhering to the dust removal plate 6, and the scraped dust will fall to the bottom of the cylindrical barrel 2; during the falling of the dust, the baffle 12 moves to a position away from the bottom hole 13, so that the baffle 12 and the bottom hole 13 are misaligned, and the dust can fall into the collecting block 10 under the action of the brush layer 9 to complete the collection of the dust; during the period when the collecting block 10 collects dust, as the weight of the dust continues to increase, that is, the weight of the dust accumulation will become heavier and heavier, until the dust When the weight of the accumulated dust reaches a certain value, the collecting block 10 is driven to move vertically downward, triggering the alarm 16 to sound an alarm, reminding the worker that the amount of dust accumulated in the box needs to be cleaned; and, by adhering the dust in the air to the dust removal plate 6, and then scraping and collecting the dust on the dust removal plate 6, on the one hand, the amount of dust in the air is reduced, so that when the air is discharged along the air outlet of the cylindrical tube 2, the air can reduce the pollution to the environment and the harm to the human body. On the other hand, by accumulating dust on the collecting block 10 to trigger the alarm 16 to sound an alarm, it is ensured that dust will not accumulate on the alarm 16, that is, the alarm 16 will not be disturbed by the dust, ensuring that the alarm 16 can always be in an efficient working state.

[0060] The first electrode ball 14 and the second electrode ball 15 are provided so that only when the weight of the dust accumulation in the collecting block 10 reaches a specified value, the collecting block 10 will move to a specified position, so that the first electrode ball 14 contacts the second electrode ball 15, triggering the alarm 16 to realize power-on operation and sound an alarm, so as to remind the workers that the weight of the dust accumulation in the collecting block 10 has reached a maximum value, thereby facilitating the workers to clean the dust in the collecting block 10 in time; and, through the above process, it is ensured that the alarm 16 can be triggered to sound an alarm only when the collecting block 10 collects a certain amount of dust, thereby ensuring the accuracy of the alarm 16 sounding an alarm, that is, the alarm 16 will not give a false alarm.

[0061] While the alarm 16 is sounding, the worker can remove the collecting block 10 from the material taking port of the hollow seat 1, and then clean the dust on the collecting block 10, so that the collecting block 10 is reset under the action of the first spring 17, so as to prepare for the dust control in the workshop again.

[0062] While the arc-shaped rack 31 drives the baffle 12 to make circumferential reciprocating motion, the impact block 37 moves synchronously; during the movement of the impact block 37, the impact block 37 can intermittently impact the copper disk 36, thereby causing the copper disk 36 to make a sound; the sound intermittently transmitted by the copper disk 36 can provide an early warning for the operation of the entire device; when the sound is emitted intermittently, it can remind the worker that the drive shaft 38 is rotating normally, thereby ensuring that all structures of the cylindrical barrel 2 are operating normally, that is, the dust collection work in the air, the filtration of the air, the detection of the amount of dust accumulation, etc. are all carried out efficiently; and if the sound of the copper disk 36 is no longer emitted, it means that the drive shaft 38 of the equipment has stopped rotating, so that the dust collection work, the filtration of the air, and the detection of the amount of dust accumulation are no longer carried out, and the workers are required to inspect and repair the equipment in time to ensure that the equipment can work efficiently again.

[0063] The auxiliary block 20 is provided to push the dust scattered at the bottom of the cylindrical barrel 2 to the position of the bottom hole 13, and under the action of the bristle layer 9, the dust scattered at the bottom of the cylindrical barrel 2 can also fall on the collecting block 10 to complete the collection of the dust, thereby improving the efficiency of dust collection and ensuring that the dust dropped at the bottom of the collecting barrel can be collected more comprehensively and thoroughly; and, since the distance between the guide block 29 and the dust removal plate 6 is equal to the length of the auxiliary block 20, a through groove for the movement of dust can be formed between the guide block 29 and the dust removal plate 6; on the one hand, the through groove can limit the movement direction of the dust and ensure that the dust will not deviate from the movement trajectory, that is, the dust can move to the position of the bottom hole 13 and finally fall on the collecting block 10; on the other hand, the auxiliary block 20 can drive more dust to the position of the bottom hole 13, thereby enhancing the effect of the auxiliary block 20 and improving the efficiency of the auxiliary block 20.

[0064] During the intermittent rotation of the dust removal plate 6, the push block 23 moves synchronously driven by the auxiliary plate 21; during the movement of the push block 23, when the push block 23 abuts against the disc 28, the disc 28 drives the short shaft 25 to rotate, and the torsion spring 26 stretches, so that the disc 28 no longer seals the circular hole 27 under the action of the push block 23, and the air can be discharged through the circular hole 27; when the push block 23 no longer abuts against the disc 28, the torsion spring 26 drives the short shaft 25 to reset, so that the disc 28 seals the circular hole 27 again, and the air cannot be discharged through the circular hole 27; through the above Movement, on the one hand, can make the air flowing in the cylindrical barrel 2, and then the dust mixed in the air adhere to the dust removal plate 6, and then can be automatically discharged along the disc 28, without manual operation, saving workers unnecessary trouble at work, on the other hand, because the disc 28 is intermittently misaligned with the circular hole 27, therefore, the air can stay longer in the cylindrical barrel 2 and contact with the dust removal plate 6 longer, ensuring that the dust in the air can be fully adhered to the dust removal plate 6, thereby enhancing the cleaning effect of the dust in the air.

[0065] The filter 24 is provided to further filter the air discharged along the circular hole 27 so as to further reduce the amount of dust contained in the air, that is, to purify the air and ensure that when the air is discharged, it will not pollute the environment of the workshop and will not harm the human body.

It should be pointed out that for those skilled in the art, without departing from the technical solution of the present invention, several modifications and improvements can be made, which should also be regarded as the protection scope of the present invention, and these will not affect the effect of the implementation of the present invention and the practicality of the patent.
