[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] (1) When the stepper motor of the present invention is not running, the device is in the filtering stage. The air containing dust enters the cylinder through the air inlet pipe and is filtered by the filter tank below. The filtered dust remains in the filter tank and the filtered air is discharged through the air outlet pipe. After filtering for a period of time, too much dust accumulates in the filter tank, affecting the filtering effect. At this time, the stepper motor is turned on and the stepper motor controls the filter mechanism to rotate. When the filter mechanism rotates °, the filter tank on the other side is rotated to the bottom of the air inlet pipe, thereby realizing rapid switching of the filter tank. At the same time, the notch of the filter tank where dust has been accumulated is inverted, and then the dust in the filter tank is poured out to realize the cleaning operation. Part of the dust is directly poured out of the dust outlet tank, and part of the dust is pushed out of the dust outlet tank through the rotation of the baffle plate, thereby realizing the automatic filtering and cleaning operation of the air dust by the device and maintaining long-term separation and treatment of dust.

[0022] (2) The present invention uses a sliding connection between a scraper and a slide groove. When the stepper motor is running, as the filter groove rotates, the two filter grooves repeatedly switch between a horizontal state and an inclined state. At this time, the scraper automatically slides in the slide groove due to its own weight, so that the scraper can scrape the filter screen plate back and forth in the filter groove to prevent dust from adhering to the filter screen plate, thereby improving the cleaning effect and preventing the filter screen plate from being blocked.

[0023] (3) When the stepper motor of the present invention enters the dust cleaning stage, the filter screen is first cleaned by the falling of dust itself and the scraping of the scraper. At the same time, after rotating to a certain angle, the fan will briefly blow in the opposite direction to the filter slot with the slot facing away from the fan, so that the dust remaining after the scraper is scraped can be more easily blown into the dust outlet slot, further improving the cleaning effect. At the same time, due to the cooperation of the anti-dust mechanism of the present invention, under the blocking of the blocking plate, the wind blown by the fan does not directly affect the dust filter bag below the dust outlet slot, thereby avoiding the occurrence of dust problems.

[0024] (4) The present invention cooperates with the dust prevention mechanism and the filtering mechanism. When the stepper motor enters the dust cleaning stage, the rotation of the filtering mechanism causes the filter slot and the baffle plate to rotate. The filter slot and the baffle plate at one end close to the side wall of the cylinder act on a plurality of arc surface structures in turn, causing the corresponding baffle plates to rotate along the rotating rod, thereby enlarging the slots between the baffle plates and making it easier for dust to fall out. After the filter slot and the baffle plate at one end close to the side wall of the cylinder release the action on the arc surface structure, the baffle plate reverses and resets under the rebound of the first spring, thereby realizing the back and forth rotation of the baffle plate, achieving the dust shaking-off effect, further improving the dust collection efficiency, and preventing the dust outlet slot from being blocked.

[0025] (5) The present invention can quickly fix the dust filter bag and quickly remove the dust filter bag through the design of the fixing mechanism. Specifically, when the dust filter bag needs to be fixedly connected to the dust outlet slot, the type N hook is hung into the hanging slot, and then the bag opening of the dust filter bag is hooked on the limit plate, and the screw is tightened so that the limit plate presses the outer wall of the dust outlet slot to fix it, and then the other edges of the bag opening of the dust filter bag are inserted between the pressure plate and the side wall of the dust outlet slot, and the pressure plate is further pressed by the action of the second spring. When the dust filter bag needs to be removed, the dust filter bag can be directly lifted up and then pulled down. First, lift it up to make the type N hook detach from the hanging slot, and then pull it down to make the bag opening of the dust filter bag leave the pressure plate.

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solution and advantages of the present invention clearer, the present invention is further described in detail below in conjunction with the embodiments. Of course, the specific embodiments described here are only used to explain the present invention and are not used to limit the present invention.

[0040] Although the steps in the present invention are arranged with numbers, they are not used to limit the order of the steps. Unless the order of the steps is clearly stated or the execution of a certain step requires other steps as a basis, the relative order of the steps can be adjusted. It is understood that the term "and / or" used in this article involves and covers any and all possible combinations of one or more of the associated listed items. Example

[0041] like Figure 1 to Figure 11 As shown, a dust separation and processing device comprises a barrel 100, on the side wall of which an air inlet pipe 110, an air outlet pipe 120 and a dust outlet slot 130 are respectively connected; both ends of the barrel 100 are mounted on a bracket 700; a stepper motor 600 is fixedly mounted in the middle of one end of the barrel 100, the output shaft of the stepper motor 600 passes through the barrel 100 and the output shaft of the stepper motor 600 is fixedly connected to a filter mechanism 800, and the filter mechanism 800 is located inside the barrel 100;

[0042] It is worth noting that the stepper motor 600 of the present invention can be fixedly rotated at a certain angle, for example, the filter mechanism 800 can be fixedly rotated 180°; at the same time, the stepper motor 600 is controlled by an external power supply, which is a prior art and will not be described in detail here.

[0043] The filtering mechanism 800 includes a rotating shaft 810, one end of which is fixedly connected to the output shaft of the stepping motor 600; two filtering grooves 830 and two baffles 820 are evenly and fixedly connected to the side wall of the rotating shaft 810, the filtering grooves 830 and the baffles 820 are arranged at intervals, and the notches of the two filtering grooves 830 are in opposite directions; one end of the filtering grooves 830 and the baffles 820 close to the side wall of the cylinder 100 are both in contact with the side wall of the cylinder 100;

[0044] When the stepper motor 600 is not running, the notch of one of the filter slots 830 is aligned with the air inlet pipe 110 , the end of the filter slot 830 away from the notch is aligned with the air outlet pipe 120 , and the notch of the other filter slot 830 is aligned with the dust outlet slot 130 .

[0045] When the stepper motor 600 of the present invention is not running, the device is in the filtering stage. The air with dust enters the interior of the cylinder 100 through the air inlet pipe 110 and is filtered by the filter tank 830 below. The filtered dust remains in the filter tank 830 and the filtered air is discharged through the air outlet pipe 120. After filtering for a period of time, too much dust accumulates in the filter tank 830, affecting the filtering effect. At this time, the stepper motor 600 is turned on, and the stepper motor controls the filter mechanism 600 to rotate. When the filter mechanism 600 rotates 1 After 80°, the filter slot 830 on the other side is rotated to the bottom of the air inlet pipe 110, so as to realize the rapid switching of the filter slot 830. At the same time, the slot of the filter slot 830 where dust was previously accumulated is inverted, and then the dust in the filter slot 830 is poured out to realize the cleaning operation. Part of the dust is directly poured out of the dust outlet slot 130, and part of the dust is pushed out of the dust outlet slot 130 through the rotation of the baffle plate 820, thereby realizing the automatic filtering and cleaning operation of the air dust by the device and maintaining the long-term separation and treatment of the dust.

[0046] Furthermore, the bottom of the filter tank 830 is a filter screen plate 831, and the inner sides of the two side walls of the filter tank 830 close to the two ends of the cylinder 100 are provided with slide grooves 832. The filter screen plate 831 is provided with a scraper 833, and the two ends of the scraper 833 are respectively slidably connected to the corresponding slide grooves 832.

[0047] The present invention uses the sliding connection between the scraper 833 and the slide groove 832. When the stepper motor 600 is running, as the filter groove 830 rotates, the two filter grooves 830 repeatedly switch between a horizontal state and an inclined state. At this time, the scraper 833 automatically slides in the slide groove 832 by its own weight, so that the scraper 833 can scrape the filter screen plate 831 back and forth in the filter screen plate 831 to prevent dust from sticking to the filter screen plate 831, thereby improving the cleaning effect and preventing the filter screen plate 831 from being blocked.

[0048] Furthermore, a shovel tooth 821 is fixedly provided at one end of the baffle plate 820 close to the side wall of the cylinder 100, and the shovel tooth 821 is in contact with the inner wall of the side wall of the cylinder 100. The shovel tooth 821 improves the removal effect of some dust.

[0049] Furthermore, a fan 200 is installed at the end of the air inlet pipe 110, and a first filter screen 121 is fixedly provided at one end of the air outlet pipe 120 close to the cylinder 100. An isolation mechanism 300 is installed in the air outlet pipe 120, and the isolation mechanism 300 includes filter cotton 320 and a filter end cover 310. The filter cotton 320 is inserted into the interior of the air outlet pipe 120; the filter end cover 310 is fixedly connected to the air outlet pipe 120 by bolts on all sides, and a second filter screen 311 is provided in the middle of the filter end cover 310.

[0050] It is worth noting that the fan 200 of the present invention is also controlled by an external power supply; at the same time, through the setting of the isolation mechanism 300, the filter cotton 320 can further improve the dust separation effect while preventing part of the dust inside the cylinder 100 from escaping from the exhaust pipe 120, and the filter cotton 320 can be replaced regularly.

[0051] Furthermore, a dust prevention mechanism 400 is installed inside the dust outlet groove 130, and the dust prevention mechanism 400 includes a plurality of rotating rods 410, and the two ends of the rotating rods 410 are respectively fixedly connected to the front and rear inner walls of the dust outlet groove 130; the plurality of rotating rods 410 are evenly spaced in the dust outlet groove 130; a rotating drum 420 is sleeved on the rotating rod 410, and a partition plate 421 is fixedly connected to the side wall of the rotating drum 420.

[0052] Furthermore, the front and rear ends of the baffle plate 421 are fixedly connected with a slide rod 440, and a limit block 430 is fixedly provided on the inner wall of the dust outlet groove 130 close to the slide rod 440. The slide rod 440 passes through the opening in the middle of the corresponding limit block 430, and the end of the slide rod 440 away from the baffle plate 421 is an arc surface structure 460, and the arc surface structure 460 is located inside the cylinder 100; the slide rod 440 is sleeved with a first spring 450, and the two ends of the first spring 450 are respectively fixedly connected to the limit block 430 and the baffle plate 421.

[0053] It is worth noting that the opening size in the middle of the limit block 430 should be larger than the outer diameter of the sliding rod 440 to prevent the sliding rod 440 and the limit block 430 from getting stuck.

[0054] When the stepper motor 600 enters the dust cleaning stage, the dust filter 831 is first cleaned by the dust falling off and the scraper 833 scraping. Figure 7As shown in state 1, after rotating a certain angle, the fan 200 will briefly blow back the filter slot 830 with the slot facing away from the fan 200, so that the dust remaining after being scraped by the scraper 833 is more easily blown into the dust outlet slot 130, further improving the cleaning effect; at the same time, due to the cooperation of the anti-dust mechanism 400 of the present invention, under the blocking of the blocking piece 421, the wind blown by the fan 200 does not directly affect the dust filter bag under the dust outlet slot 130, thereby avoiding the occurrence of dust problems.

[0055] It is worth mentioning that when entering the cleaning stage, the stepper motor 600 rotates 180° and then stops. This process will not be too long, so the fan 200 will briefly blow back the filter slot 830 with the slot facing away from the fan 200. At this time, even if the air outside the device contains dust, it is only a small amount and will not affect the blowing filter slot 830.

[0056] At the same time, if Figure 7 As shown in state 2, when at a certain angle, the two baffles 820 will completely block the air inlet pipe 110. At this time, the wind blown in by the fan 200 will finally perform a final temporary closed blowing on the filter tank 830, so that the residual dust will quickly fall off from both sides of the filter tank 830, thereby preventing dust from adhering to the filter tank 830 and deeply improving the cleaning effect.

[0057] Furthermore, the height of the end of the baffle plate 421 away from the corresponding rotating drum 420 is lower than the height of the rotating drum 420. This design facilitates dust to fall into the dust outlet slot 130 through the baffle plate 421.

[0058] The present invention cooperates with the anti-dust mechanism 400 and the filter mechanism 800. When the stepper motor 600 enters the dust cleaning stage, the rotation of the filter mechanism 800 causes the filter slot 830 and the baffle plate 820 to rotate. The filter slot 830 and the baffle plate 820, one end of which is close to the side wall of the cylinder 100, act on the multiple curved structures 460 in turn, causing the corresponding baffle plates 421 to rotate along the rotating rod 410, so that the notches between the baffle plates 421 become larger, allowing dust to fall out more easily. After the filter slot 830 and the baffle plate 820, one end of which is close to the side wall of the cylinder 100, release the action on the curved structure 460, the baffle plate 421 is reversed and reset under the rebound of the first spring 450, thereby realizing the back and forth rotation of the baffle plate 421, achieving the dust shaking-off effect, and further improving the dust collection efficiency. At the same time, it can also prevent the dust outlet slot 130 from being blocked.

[0059] Furthermore, a fixing mechanism 500 is installed on the outer side wall of the dust outlet trough 130 for fixing the dust filter bag; the fixing mechanism 500 includes a type n hook 520, and a plurality of hanging grooves 510 are provided on the two opposite side walls of the dust outlet trough 130. The type n hook 520 is hung on the hanging groove 510, and a screw 530 is threadedly connected to the side wall of the type n hook 520. The screw 530 is located outside the dust outlet trough 130, and the screw 530 passes through the side wall of the type n hook 520 and the end A limit plate 540 is fixedly provided, and the limit plate 540 is used to limit and fix the bag opening of the dust filter bag; a plurality of limit rods 550 are fixedly connected to the other two opposite side walls of the dust outlet groove 130, and a protrusion is provided at the end of the limit rod 550 away from the dust outlet groove 130, and a pressure plate 560 and a second spring 570 are sleeved on the limit rod 550, and the two ends of the second spring 570 are respectively fixedly connected to the pressure plate 560 and the protrusion of the limit rod 550, and the pressure plate 560 is used to press the bag opening of the dust filter bag.

[0060] The present invention can quickly fix the dust filter bag and quickly remove the dust filter bag through the design of the fixing mechanism 500. Specifically, when the dust filter bag needs to be fixedly connected to the dust outlet trough 130, the n-type hook 520 is hung in the hanging groove 510, and then the bag opening of the dust filter bag is hooked on the limit plate 540, and the screw 530 is tightened so that the limit plate 540 presses the outer wall of the dust outlet trough 130 to achieve fixation, and then the other edges of the bag opening of the dust filter bag are inserted between the pressure plate 560 and the side wall of the dust outlet trough 130, and the pressure plate 560 is further pressed by the force of the second spring 570. When the dust filter bag needs to be removed, the dust filter bag can be directly lifted up and then pulled down. First, lift it up to make the n-type hook 520 disengage from the hanging groove 510, and then pull it down to make the bag opening of the dust filter bag leave the pressure plate 560.

[0061] It is worth noting that if the dust filter bag cannot be lifted, the screw 530 can be loosened appropriately.

[0062] Furthermore, two support columns 710 are provided above the bracket 700, one of which is fixedly connected to a limiting ring 720, and a rotating groove 721 is provided on the inner wall of the limiting ring 720; a receiving shaft 140 is fixedly connected to the middle part of the end of the cylinder 100 away from the stepping motor 600, and the receiving shaft 140 passes through the limiting ring 720, and a rotating ring 141 is fixedly provided on the side wall of the receiving shaft 140, and the rotating ring 141 is rotatably connected to the rotating groove 721; a threaded opening is provided through the limiting ring 720 and a locking knob 740 is screwed thereon, and the locking knob 740 is used to lock the rotating ring 141.

[0063] Furthermore, a plurality of connecting columns 151 are fixedly connected around one end of the cylinder 100 close to the stepper motor 600, and one end of the connecting columns 151 is fixedly connected to a receiving ring 150; a supporting column 710 located on the side close to the stepper motor 600 is fixedly connected to a receiving groove 730, and a receiving notch 731 is provided on the receiving groove 730, and the receiving notch 731 abuts and limits the receiving ring 150.

[0064] By means of the rotational connection between the rotating ring 141 and the rotating groove 721, the barrel 100 can be rotated and fine-tuned at a certain angle, thereby fine-tuning the direction of the air intake pipe 110. The locking knob 740 is a screw-like structure and can be used to lock the rotating ring 141 to fix the barrel 100. Through the function of the receiving groove 731 and the receiving ring 150, the barrel 100 can be stably supported without affecting the fine-tuning rotation of the barrel 100.

[0065] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several improvements and changes without departing from the creative concept of the present invention, which all belong to the protection scope of the present invention.
