Technical Field

[0001] The present invention relates to the technical field of air pollution control, and in particular to an automatic product dust collection device. Background Art

[0002] When processing vehicle metal parts, metal dust often appears. After the metal dust is discharged into the environment, it will enter the soil and water bodies through atmospheric deposition and rainwater erosion, causing soil and water pollution, thereby affecting the growth of crops and the survival of aquatic organisms, and causing air pollution.

[0003] The existing publication number is CN109011852A, and it is titled as a spiral metal dust collection device, comprising a diverging tube, a housing, a motor, and blades. The blades are fixed to the motor shaft of the motor. The blades are disposed within the housing. One end of the housing is open, and the airflow generated by the rotation of the blades driven by the motor enters the housing axially through the opening. The side wall of the housing is provided with an exhaust port, and the airflow generated by the rotation of the blades driven by the motor is discharged circumferentially from the housing through the exhaust port. The inlet diameter of the diverging tube is smaller than the outlet diameter, and the inlet of the diverging tube is connected to the exhaust port of the housing.

DETAILED DESCRIPTION

[0034] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0035] Example 1, reference Figure 1-2 A product dust automatic collection device includes a separation box 2 and an air inlet pipe 1 and an air outlet pipe 13 installed on the separation box 2. A second chamber 6 is provided at the middle end of the separation box 2. The second chamber 6 is symmetrically rotated with two rollers 7. The rollers 7 are connected to the driving member through a connecting shaft 22. A plurality of filter discs 8 are evenly fixed on the outer surfaces of the two rollers 7. The filter discs 8 on the two rollers 7 are staggered when rotating.

[0036] Air inlets 3 are provided on both sides of the separation box 2 , and the regulating component 4 is communicated with the air inlets 3 on the same side, and the position of the regulating component 4 matches the position of the drum 7 .

[0037] The driving part includes a transmission part, a transmission tooth 16, a stepper motor 17 and a chassis 21; the transmission tooth 16 is installed at the end of the two connecting shafts 22, and the two transmission teeth 16 are engaged with each other, one of the transmission teeth 16 is connected to the output shaft of the stepper motor 17 through a rotating shaft, and the stepper motor 17 is installed on one side of the interior of the chassis 21.

[0038] The transmission parts include a transmission wheel 18, a circular shaft 19 and a transmission belt 20. One end of the circular shaft 19 is installed at the center of the magnetic bar 9. Transmission wheels 18 are installed on one end of the two circular shafts 19 and the output shaft of the stepper motor 17. The transmission belt 20 is sleeved on the inner side of multiple transmission wheels 18. The transmission belt 20 and multiple transmission wheels 18 are all located on the inner side of the chassis 21.

[0039] The gas carrying metal dust enters the separation box 2 from the air inlet pipe 1. Due to the gravity of the metal dust itself, it falls on the filter 8 outside the drum 7 when passing through the two rollers 7. The rotation direction of the two drums 7 is controlled by two mutually meshing transmission teeth 16 on the outside, so that the rotation directions of the two drums 7 are opposite, and the drum 7 on the right rotates clockwise. In this way, when the metal dust falls on the filter 8, the filter 8 tends to rotate upward, and the metal dust will roll to the angle position between the filter 8 and the drum 7. When the metal dust collected on the filter 8 rotates to the other side of the second chamber 6, the metal dust will slide along the inclined filter 8. In this process, with the help of the metal dust's own gravity, it is transferred from the gas to the filter 8, and then from the filter 8 to the other side of the second chamber 6. In the process of rotation of the drum 7, the filter 8 on the two drums 7 are staggered, so that as much metal dust as possible can fall on the filter 8.

[0040] Example 2, reference Figure 3-7 The difference between this embodiment and embodiment 1 is that the regulating component 4 includes a connector 401, a windshield 402 and a bellows 403. The bellows 403 is located at the upper inner end of the second chamber 6 and is connected to the air inlet 3. The position of the bellows 403 matches the position of the drum 7. Several windshields 402 are movable in the bellows 403 through the connector 401.

[0041] The connecting member 401 includes a gear 4011, a rack 4012 and a guide rail 4013. The guide rail 4013 is arranged at the inner bottom of the bellows 403. The rack 4012 is located on the inner side of the guide rail 4013. The gear 4011 is located at the bottom of the wind shield 402. The gear 4011 and the rack 4012 are engaged with each other. One end of the rack 4012 extends to the outside of the separation box 2. One end of the rack 4012 is connected to the telescopic rod 23. The telescopic rod 23 is installed on the outside of the separation box 2 through the bracket 15.

[0042] Since the metal powder falls on the filter 8, an irregular concave-convex surface is formed between the filter 8 and the roller 7. As a result, the conventional use of a fan to blow it off is not very effective.

[0043] To this end, a regulating assembly 4 is set at the matching position of the drum 7. The regulating assembly 4 includes a connecting member 401, a windshield 402 and a bellows 403. At the same time, the connecting member 401 is composed of a gear 4011, a rack 4012 and a guide rail 4013. The air inlet 3 is connected to the fan to conduct the air flow into the bellows 403. The rack 4012 moves linearly back and forth in the guide rail 4013 through the telescopic rod 23 after the power is turned on. During the movement of the rack 4012, the gear 4011 is driven to rotate. During the rotation, the windshield 402 on the upper part of the gear 4011 2 achieves synchronous deflection, and the movement of the plurality of windshields 402 is consistent. When the windshields 402 deflect within the bellows 403, the direction of the airflow blown out by the bellows 403 can be effectively changed, and the metal dust between the roller 7 and the filter 8 can be blown off from multiple directions. Secondly, the roller 7 and the filter 8 rotate between the second chamber 6 and the inside of the air inlet pipe 1, dividing the second chamber 6 and the air inlet pipe 1 into two independent spaces, reducing the airflow from the bellows 403 from disturbing the airflow flowing from the air inlet pipe 1 to the air outlet pipe 13, and ensuring that the falling path of the metal dust does not change.

[0044] Example 3, reference Figure 3 The difference between this embodiment and embodiment 1 and embodiment 2 is that the first chamber 5 is symmetrically arranged on both sides of the lower end of the second chamber 6, and a cleaning component is arranged on the inner side of the first chamber 5. The cleaning component includes a magnetic rod 9, a scraper 10 and a second channel 12. The magnetic rod 9 is rotatably arranged on the inner side of the first chamber 5, and the second channel 12 is obliquely opened at the bottom of the separation box 2. The first chamber 5 is connected to the outside through the second channel 12. A scraper 10 is arranged at the upper end of the second channel 12, and the scraper 10 is in contact with the outer surface of the magnetic rod 9.

[0045] A first channel 11 is further provided between the bottom of the first chamber 5 and the second channel 12, and the bottom of the first chamber 5 is inclined. The bottom of the first chamber 5 has the same inclination as the second channel 12. A slope 14 is provided under the drum 7, and the slope 14 is connected to the upper eaves of the first chamber 5, and the slope 14 is inclined downward toward the direction of the first chamber 5.

[0046] In order to prevent the collected dust from being scattered, a first chamber 5 is set at the lower end of the second chamber 6, and a rotatable magnetic rod 9 is set inside the first chamber 5. The collected metal dust is also of the type that can be adsorbed by the magnetic rod 9, such as iron powder. The magnetic rod 9 is powered by a stepper motor 17, and a plurality of transmission wheels 18 cooperate with the transmission belt 20 to transfer kinetic energy to the circular shaft 19, thereby realizing rotation. Since the position of the first chamber 5 is located at the bottom of the second chamber 6, and the setting of the inclined surface 14 is cooperated, the fallen metal dust will roll down to The inner side of the first chamber 5 can adsorb the falling metal powder on the outer surface as the magnetic bar 9 rotates. When the dust adsorbed on the surface of the magnetic bar 9 reaches a certain level, the magnetic bar 9 will contact the scraper 10 on one side when rotating. The scraper 10 is a thin steel sheet. In the process of contacting the magnetic bar 9, the scraper 10 vibrates, and the reaction force generated by the shaking is fed back to the magnetic bar 9, forming an intermittent beating of the magnetic bar 9, which helps the metal dust on the magnetic bar 9 to slide smoothly and roll down and be collected from the second channel 12.

[0047] Secondly, during the rotation of the magnetic rod 9, some metal powder will fall directly to the inner bottom of the first chamber 5. The bottom of the first chamber 5 is inclined, and the falling metal powder will roll down from the first channel 11 and finally gather in the second channel 12 and be discharged together. During this process, the airflow in the second chamber 6 can also play a certain role in the rolling of dust.

[0048] The working principle of the device is:

[0049] The gas carrying metal dust enters the separation box 2 from the air inlet pipe 1. Due to the gravity of the metal dust itself, it falls on the filter 8 outside the drum 7 when passing through the two rollers 7. The rotation direction of the two drums 7 is controlled by two mutually meshing transmission teeth 16 on the outside, so that the rotation directions of the two drums 7 are opposite, and the drum 7 on the right rotates clockwise. In this way, when the metal dust falls on the filter 8, the filter 8 tends to rotate upward, and the metal dust will roll to the angle position between the filter 8 and the drum 7. When the metal dust collected on the filter 8 rotates to the other side of the second chamber 6, the metal dust will slide along the inclined filter 8. In this process, with the help of the metal dust's own gravity, it is transferred from the gas to the filter 8, and then from the filter 8 to the other side of the second chamber 6. In the process of rotation of the drum 7, the filter 8 on the two drums 7 are staggered, so that as much metal dust as possible can fall on the filter 8.

[0050] Since the metal powder falls on the filter 8, an irregular concave-convex surface is formed between the filter 8 and the roller 7. As a result, the conventional use of a fan to blow it off is not very effective.

[0051] To this end, a regulating assembly 4 is set at the matching position of the drum 7. The regulating assembly 4 includes a connecting member 401, a windshield 402 and a bellows 403. At the same time, the connecting member 401 is composed of a gear 4011, a rack 4012 and a guide rail 4013. The air inlet 3 is connected to the fan to conduct the air flow into the bellows 403. The rack 4012 moves linearly back and forth in the guide rail 4013 through the telescopic rod 23 after the power is turned on. During the movement of the rack 4012, the gear 4011 is driven to rotate. During the rotation, the windshield 402 on the upper part of the gear 4011 2 achieves synchronous deflection, and the movement of the plurality of windshields 402 is consistent. When the windshields 402 deflect within the bellows 403, the direction of the airflow blown out by the bellows 403 can be effectively changed, and the metal dust between the roller 7 and the filter 8 can be blown off from multiple directions. Secondly, the roller 7 and the filter 8 rotate between the second chamber 6 and the inside of the air inlet pipe 1, dividing the second chamber 6 and the air inlet pipe 1 into two independent spaces, reducing the airflow from the bellows 403 from disturbing the airflow flowing from the air inlet pipe 1 to the air outlet pipe 13, and ensuring that the falling path of the metal dust does not change.

[0052] In order to prevent the collected dust from being scattered, a first chamber 5 is set at the lower end of the second chamber 6, and a rotatable magnetic rod 9 is set inside the first chamber 5. The collected metal dust is also of the type that can be adsorbed by the magnetic rod 9, such as iron powder. The magnetic rod 9 is powered by a stepper motor 17, and a plurality of transmission wheels 18 cooperate with the transmission belt 20 to transfer kinetic energy to the circular shaft 19, thereby realizing rotation. Since the position of the first chamber 5 is located at the bottom of the second chamber 6, and the setting of the inclined surface 14 is cooperated, the fallen metal dust will roll down to The inner side of the first chamber 5 can adsorb the falling metal powder on the outer surface as the magnetic bar 9 rotates. When the dust adsorbed on the surface of the magnetic bar 9 reaches a certain level, the magnetic bar 9 will contact the scraper 10 on one side when rotating. The scraper 10 is a thin steel sheet. In the process of contacting the magnetic bar 9, the scraper 10 vibrates, and the reaction force generated by the shaking is fed back to the magnetic bar 9, forming an intermittent beating of the magnetic bar 9, which helps the metal dust on the magnetic bar 9 to slide smoothly and roll down and be collected from the second channel 12.

[0053] Secondly, during the rotation of the magnetic rod 9, some metal powder will fall directly to the inner bottom of the first chamber 5. The bottom of the first chamber 5 is inclined, and the falling metal powder will roll down from the first channel 11 and finally gather in the second channel 12 and be discharged together. During this process, the airflow in the second chamber 6 can also play a certain role in the rolling of dust.
