Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of food dust particle detection, in particular to a dust particle detector for food standardization detection. Background Art
[0002] In the food production industry, food safety and hygiene standards are directly related to public health and product quality. Dust particles, as common pollutants in the production environment, may carry microorganisms, harmful particles, or allergens, posing a potential threat to the cleanliness and safety of food. Therefore, efficient and accurate detection of dust particles in the food production environment is an important step in ensuring that the production process meets hygiene standards. Currently, most common dust particle detectors on the market use suction sampling combined with optical counting technology. They inhale air samples and use particle counters to analyze dust concentration. However, existing equipment has significant shortcomings in practical applications: 1) The sampling range of traditional detectors is narrow and easily affected by local airflow or the fixed position of the equipment, resulting in uneven sampling. Especially in complex workshop environments, it is difficult to fully cover the entire area, and the test results are not representative enough. 2) After the test, dust or oil particles are likely to remain inside the equipment (such as the test chamber and pipeline). These residues may contaminate subsequent samples, causing deviations in the test data and requiring frequent shutdowns for cleaning, which seriously affects the test efficiency. 3) Existing equipment mostly relies on manual disassembly and cleaning or simple blowing, which is not only cumbersome to operate and has high maintenance costs, but also difficult to completely remove adherent particles (such as oily dust). Long-term accumulation may damage the sensor or reduce the sensitivity of the equipment. 4) Some equipment has poor control over the suspension of heavy particles (such as metal debris). Particle sedimentation during the test process will cause counting errors, affecting the accuracy of the test results. Summary of the Invention

[0014] 1. When the suction seat of the present invention is working, the electric-controlled rotary seat drives the docking rod to drive the top plate to rotate, and the detection box rotates synchronously through the connecting seat and the docking rotary seat to expand the suction range.

[0019] The following embodiments of the technical solution of the present application will be described in detail with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only examples and are not intended to limit the scope of protection of the present application.

The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.
[0021] See also Figures 1 to 9The dust particle detector for food standardization testing provided by the present invention includes a positioning component 1, a detection box 2, and an adsorption component 4. The detection box 2 is placed on the inner side of the top of the positioning component 1. The positioning component 1 includes a body 101. The top outer end of the body 101 is placed with an electric control rotating seat 102, and the top outer end of the electric control rotating seat 102 is placed with a docking rod 103. The top outer end of the docking rod 103 is provided with a top plate 104, and the front bottom end of the top plate 104 is placed with a docking seat 105. A first motor 106 is mounted on the outer end of the connecting seat 105, and a docking swivel seat 107 is provided at the output end of the first motor 106. The electrically controlled swivel seat 102 drives the docking rod 103 to rotate, and the docking rod 103 is fixedly connected to the top plate 104. The top plate 104 is distributed parallel to the vehicle body 101. The docking swivel seat 107 is connected to the detection box 2, and the first motor 106 drives the detection box 2 to rotate through the docking swivel seat 107. A suction component 3 is mounted on the outer bottom end of the detection box 2.
[0022] The suction assembly 3 includes a suction pipe 301, the end of the suction pipe 301 is provided with a suction seat 302, and a ratchet 303 is placed on the top of the suction pipe 301, and a ventilation groove 304 is opened on the inner side of the ratchet 303, the outer end of the suction pipe 301 is provided with a first pulley 305, the outer end of the detection box 2 is provided with a second motor 307, and the output end of the second motor 307 is provided with a second pulley 308, a belt 306 is provided between the first pulley 305 and the second pulley 308, the second motor 307 drives the first pulley 305 to rotate through the second pulley 308 and the belt 306, and the first pulley 305 is fixedly connected to the suction pipe 301, the outer end of the detection box 2 is provided with a placement seat 5, and a particle counter 6 is placed inside the placement seat 5, tempered glass 7 is placed between the detection box 2 and the placement seat 5, and a suction pump 8 is placed at the top outer end of the detection box 2.
[0023] The staff pushes the equipment to move into the food standardization testing workshop, and the suction pump 8 starts working. The suction force of the suction pump 8 is transmitted to the inside of the suction seat 302 through the testing box 2, the ventilation groove 304, and the suction pipe 301, so that the suction seat 302 can bring the air in the food standardization testing workshop into the inside of the testing box 2. In the process of the suction seat 302 sucking air, the docking rod 103 is driven to rotate by the electric control rotary seat 102, which can make the top plate 104 rotate in a circle. Because the top plate 104 is connected with the testing box 2 through the connecting seat 105 and the docking rotary seat 107, the testing box 2 can rotate in a circle with the top plate 104, which improves the suction range of the suction seat 302. At the same time, the second pulley 308 is driven to rotate by the second motor 307, which can make the belt 306 drive the first pulley 305 to rotate. Now, because the first pulley 305 is fixed to the suction pipe 301, the suction pipe 301 can drive the suction seat 302 to rotate in a circle, which further expands the suction range of the suction seat 302. By improving the suction range of the suction seat 302, it is possible to avoid the situation where only a small range of suction is performed in the food standardization testing workshop, resulting in inaccurate test results. After the external gas enters the interior of the testing box 2, the particle counter 6 inside the placement seat 5 works and can count the dust particles in the air in the testing box 2 through the tempered glass 7. During the detection process of the particle counter 6, the first motor 106 drives the docking turntable 107 to rotate, which can make the testing box 2 flip over. By flipping the testing box 2, it is possible to avoid the situation where heavier dust sinks to the bottom of the testing box 2 and affects the detection accuracy of the particle counter 6.
[0024] See also Figures 1 to 9, the interior of the detection box 2 is provided with an adsorption component 4, the adsorption component 4 includes a rotating seat 401, a pressure spring 402 is provided inside the rotating seat 401, and a ratchet 403 is provided at the outer end of the pressure spring 402, a cleaning frame 404 is provided at the top outer end of the rotating seat 401, and a first electric push rod 405 is provided inside the cleaning frame 404, an insulating plate 406 is provided at the output end of the first electric push rod 405, and an adsorption plate 407 is provided on the side of the insulating plate 406 away from the first electric push rod 405, a battery 408 is provided inside the cleaning frame 404, and a connecting line 409 is connected between the battery 408 and the adsorption plate 407, a second electric push rod 410 is provided at the outer end of the cleaning frame 404, and the second electric push rod 410 is provided 0 A displacement plate 411 is placed at the output end, the outer end of the displacement plate 411 is connected to the collection seat 412, and an exhaust fan 413 is placed inside the collection seat 412, and a partition net 414 is placed at the outer end of the exhaust fan 413. A scraper 415 is placed at the outer end of the collection seat 412, and a suction groove 416 is opened inside the scraper 415. The suction pipe 301 is fixedly connected to the ratchet 303, and the ratchet 303 is engaged with the ratchet teeth 403. The battery 408 is electrically connected to the adsorption plate 407 through the connecting line 409, and the second electric push rod 410 drives the displacement plate 411 to displace the scraper 415 so that the scraper 415 contacts the adsorption plate 407. The scraper 415 and the collection seat 412 are an integrated structure, and the suction groove 416 is connected to the inside of the collection seat 412.
[0025] It should be noted that when the suction seat 302 is in the suction process, the second motor 307 rotates forward. At this time, the ratchet 303 and the ratchet teeth 403 are in a non-meshing state. When the suction pipe 301 drives the ratchet 303 to rotate, the ratchet 303 squeezes the ratchet teeth 403, which allows the ratchet teeth 403 to be retracted into the rotating seat 401 through the pressure spring 402, so that the rotating seat 401 does not rotate with the ratchet 303. After the particle counter 6 completes the dust particle detection, the suction pump 8 stops working and the second motor 307 rotates in the opposite direction. At this time, when the suction pipe 301 drives the ratchet 303 to rotate, the ratchet 303 engages with the ratchet teeth 403, which causes the rotating seat 401 to rotate inside the detection box 2. During the rotation of the rotating seat 401, the first electric push rod 405 works to drive the insulating plate 406 to move inside the cleaning frame 404, so that the adsorption plate 407 can be moved out from the cleaning frame 404.
[0026] During the process of moving the cleaning frame 404 out, the battery 408 works and the adsorption plate 407 is energized at high frequency through the connecting line 409, which can make the surface of the adsorption plate 407 adhere to the charge, thereby generating static electricity on the surface of the adsorption plate 407. By making the adsorption plate 407 generate static electricity and rotate it in the detection box 2, the adsorption plate 407 can adsorb the dust particles floating in the detection box 2. At the same time, the first motor 106 drives the docking seat 107 to rotate and turn the detection box 2 over, which can make the dust on the bottom continue to float until it is adsorbed by the adsorption plate 407, and the residual dust particles in the suction pipe 301 will also be sucked away. Due to the rotation and flipping into the detection box 2, through this design, the equipment can quickly clean the dust particles in the detection box 2 after the detection is completed, which can avoid the situation where the dust particles in the detection box 2 remain and affect the subsequent detection. The detection box 2 is connected to the outside with a grounding wire, and the detection box 2 is fitted with the rotating seat 401, the rotating seat 401 and the cleaning frame 404 are integrated, and the cleaning frame 404 is fitted with the scraper 415, which makes the scraper 415 also grounded. When the adsorption plate 407 completes its work and the second electric push rod 410 drives it to reset, the displacement plate 411 can be made to move by the second electric push rod 410. The collecting seat 412 and the scraper 415 are driven to move, which enables the scraper 415 to fit with the adsorption plate 407. During the resetting process of the adsorption plate 407, the scraper 415 will scrape the surface of the adsorption plate 407. At the same time, after the two are in contact, the static electricity on the surface of the adsorption plate 407 will be discharged due to grounding, which makes it easier for the scraper 415 to scrape off the dust on the surface of the adsorption plate 407. In addition, food production usually contains oil stains, and by scraping, the oil stains can also be avoided from remaining on the adsorption plate 407. A suction groove 416 is provided on the surface of the scraper 415 and is connected to the inside of the collecting seat 412. When the scraper 415 scrapes off the oil stains and dust During the process, the suction force can be transmitted to the suction groove 416 through the operation of the exhaust fan 413, which allows dust and oil stains to be sucked into the collection seat 412 for storage. Through this design, the adsorption plate 407 can be quickly cleaned after completing the dust adsorption to prevent excessive surface adsorption of dust and affecting the subsequent adsorption effect. In addition, the partition net 414 on the surface of the exhaust fan 413 can separate the oily dust from the exhaust fan 413 to prevent the oily dust from affecting the normal operation of the exhaust fan 413. A cleaning port is provided at the bottom of the collection seat 412. After collecting oily dust for a long time, the staff can open the cleaning port to clean the inside of the collection seat 412.
[0027] In summary, when using the dust particle detector for food standardization testing, a worker first pushes the device, and the device can be rolled into the food standardization testing workshop via the rollers of the vehicle body 101. At this time, the suction pump 8 works, and the suction force can be transmitted to the interior of the suction seat 302 through the testing box 2, the ventilation groove 304, and the suction pipe 301, so that the suction seat 302 can draw the air in the food standardization testing workshop into the testing box 2. Then, during the process of the suction seat 302 sucking air, the docking rod 103 is driven to rotate by the electric-controlled rotating seat 102, which can make the top plate 104 rotate in a circle. Because the top plate 104 is connected with the detection box 2 through the connecting seat 105 and the docking rotating seat 107, the detection box 2 can rotate in a circle together with the top plate 104, which improves the suction range of the suction seat 302. At the same time, the second motor 307 drives the second pulley 308 to rotate, which can make the belt 306 drive the first pulley 305 to rotate. Because the first pulley 305 is fixed to the suction pipe 301, the suction pipe 301 can drive the suction seat 302 to rotate in a circle, which further expands the suction range of the suction seat 302. By improving the suction range of the suction seat 302, it can avoid the situation that only a small range of suction is carried out in the food standardization testing workshop, resulting in inaccurate detection results. After the external air enters the detection box 2, the particle counter 6 in the mounting seat 5 starts to work, and can count the dust particles in the air in the detection box 2 through the tempered glass 7. During the detection process of the particle counter 6, the first motor 106 drives the docking rotating seat 107 to rotate, which can cause the detection box 2 to flip. By flipping the detection box 2, it can prevent heavy dust from settling to the bottom of the detection box 2 and affecting the detection accuracy of the particle counter 6. Then, when the suction seat 302 is in the process of suctioning, the second motor 307 rotates forward. At this time, the ratchet 303 and the ratchet teeth 403 are in a non-meshing state. When the suction pipe 301 drives the ratchet 303 to rotate, the ratchet 303 squeezes the ratchet teeth 403, which makes the ratchet teeth 403 retract into the inside of the rotating seat 401 through the pressure spring 402, so that the rotating seat 401 does not rotate with the ratchet 303. After the particle counter 6 completes the dust particle detection, the suction pump 8 stops working, and the second motor 307 rotates in the reverse direction. At this time, when the suction pipe 301 drives the ratchet 303 to rotate, the ratchet 303 and the ratchet teeth 403 are meshed, which makes the rotating seat 4 01 will rotate inside the detection box 2. During the rotation of the rotating seat 401, the first electric push rod 405 works to drive the insulating plate 406 to move inside the cleaning frame 404, so that the adsorption plate 407 can be moved out of the cleaning frame 404. During the movement of the cleaning frame 404, the battery 408 works and performs high-frequency power-off and power-on on the adsorption plate 407 through the connecting line 409, which can make the surface of the adsorption plate 407 attached with electric charge, thereby generating static electricity on the surface of the adsorption plate 407. By generating static electricity on the adsorption plate 407 and rotating it inside the detection box 2, the adsorption plate 407 can adsorb dust particles floating in the detection box 2. At the same time, the first motor 106 drives the docking swivel 107 to rotate and flip the detection box 2, so that the dust on the bottom continues to float until it is adsorbed by the adsorption plate 407, and the dust particles remaining in the suction pipe 301 will also enter the detection box 2 due to the rotation and flipping. Through this design, the device can quickly clean the dust particles in the detection box 2 after the detection is completed, which can prevent the dust particles in the detection box 2 from remaining and affecting subsequent detection. Then, when the adsorption plate 407 completes its work and the second electric push rod 410 drives it to reset, the second electric push rod 410 works to enable the displacement plate 411 to drive the collection seat 412 and the scraper 415 to move, so that the scraper 415 can fit with the adsorption plate 407, and in the process of resetting the adsorption plate 407, the scraper 415 will scrape the surface of the adsorption plate 407. At the same time, after the two are in contact, the static electricity on the surface of the adsorption plate 407 will be discharged due to grounding, which makes it easier for the scraper 415 to scrape off the dust on the surface of the adsorption plate 407. Food production usually contains oil stains, which can be prevented from remaining on the adsorption plate 407 by scraping them off. A suction groove 416 is provided on the surface of the scraper 415 and is connected to the interior of the collection seat 412. When the scraper 415 scrapes off the oil stains and dust, the exhaust fan 413 works, which can transmit the suction force to the suction groove 416, so that the dust and oil stains can be sucked into the collection seat 412 for storage. This design allows the adsorption plate 407 to be quickly cleaned after dust adsorption is completed to prevent excessive dust adsorption on the surface from affecting the subsequent adsorption effect. Finally, the partition net 414 on the surface of the exhaust fan 413 can separate the oil, dirt and dust from the exhaust fan 413 to prevent the oil, dirt and dust from affecting the normal operation of the exhaust fan 413. A cleaning port is provided at the bottom of the collection seat 412. After collecting oil, dirt and dust for a long time, the staff can open the cleaning port to clean the inside of the collection seat 412.
