[0002] In order to protect the health of employees, all kinds of workshops and factories are currently required to be equipped with dust removal equipment. Different types of workshops and factories are suitable for different types of dust removal equipment. Furniture factories and wood processing factories are mostly equipped with bag dust collectors to purify the air in the factory. The main reason is that bag dust collectors have high dust removal efficiency and low equipment cost. However, since the exhaust air also contains sawdust and other substances, the sawdust can easily puncture the bag, so the filtering effect is not good. In addition, the loss rate of dust bags is also very high, which is not conducive to dust removal. Summary of the invention

[0003] Based on this, it is necessary to provide an environmentally friendly air dust removal device to address the problems existing in the current dust removal devices. The wood chips generated by the processing of solid wood boards are used as air filter media, turning waste into treasure.

[0033] like Figure 1-Figure 5 As shown, an environmentally friendly air dust removal device includes a filter cartridge 100, a support frame 200, an air inlet 110, an air outlet 120 and an auger spiral 300. The filter cartridge 100 is cylindrical in shape, its axis is horizontal, and a discharge port 130 is provided on one side of its lower part. The support frame 200 is located below the filter cartridge 100. The support frame 200 and the filter cartridge 100 are elastically connected. Specifically, a compression spring 210 is provided between the support frame 200 and the filter cartridge 100. The compression spring 210 can be compressed in the vertical direction. The air inlet 110 is provided at one end of the filter cartridge 100 for blowing dusty wood chips into the filter cartridge 100. The air outlet 120 is provided at the top area of ​​the other end of the filter cartridge 100. The auger spiral 300 is provided at the top area of ​​the other end of the filter cartridge 100. 300 can rotate around its axis, the auger spiral 300 is arranged in the filter cartridge 100, the auger spiral 300 is in sliding contact with the inner circumferential wall of the filter cartridge 100, and the auger spiral 300 is divided into a first area 310, a second area 320 and a third area 330 from left to right along its axis, the first area 310 is connected to the air inlet 110, the upper air outlet 120 of the third area 330 is connected, and the lower discharge port 130 of the third area 330 is connected. The auger spiral 300 is configured so that after the volume of wood chips temporarily stored in the first area 310 reaches a preset value, the auger spiral 300 rotates around its axis.

[0034] It should also be added that the end of the first telescopic tube 410 away from the air inlet 110 is connected to a blower, which is used to transport the exhaust gas containing wood chips and dust into the first telescopic tube 410 through the blower, and the end of the second telescopic tube 420 away from the air outlet 120 is connected to an induced draft fan, which is used to draw the filtered air out of the filter cartridge 100 through the induced draft fan.

[0035] It should be added that a base 710 is provided at one end of the filter cartridge 100 , a servo motor 720 is provided on the base 710 , and an output shaft of the servo motor 720 is fixedly connected to the auger screw 300 .

[0036] When in use, the staff starts the blower and the exhaust fan. Under the driving action of the blower, air containing wood chips and dust enters the filter cartridge 100 from one end of the air inlet 110. At this time, the auger spiral 300 does not rotate, and the dust and wood chips accumulate in the first area 310. The weight of the wood chips inside the filter cartridge 100 increases, and the compression spring 210 is gradually compressed. When the amount of wood chips accumulated in the first area 310 exceeds half of the volume of the first area 310, the staff manually starts the auger spiral 300 to move the wood chips in the first area 310 to the area where the second area 320 is located, and then starts the auger spiral 300 to make the auger spiral 300 in a self-starting state. At this time, the wood chips that enter the filter cartridge 100 from the air inlet 110 are accumulated in the first area 310 again, and the compression spring 210 is further compressed. When the wood chips temporarily stored in the first area 310 When the volume reaches the preset value again (i.e., exceeds half of the volume of the first area 310), the auger screw 300 starts automatically and rotates around its axis, and the wood chips in the second area 320 move to the third area 330. Since a discharge port 130 is provided at the lower portion of the third area 330, the wood chips fall into the discharge port 130 under the action of gravity. Since the wood chips compressed by the auger screw 300 have a large surface area and a void structure, the dust and other particulate matter and impurities in the exhaust gas can be adsorbed by the wood chips when the exhaust gas passes through the wood chips, thereby achieving the effect of purifying the dust in the air. In addition, under the rotation of the auger screw 300, the dust in the air can also be centrifugally adsorbed on the inner circumferential wall of the filter cartridge 100, further reducing the dust content in the air. Finally, under the action of the negative pressure fan, the purified air is discharged outward from the air outlet 120 and enters the next air purification system.

[0037] It should be noted that the present invention uses wood chip waste in a wood processing plant as a filter medium, turning waste into treasure. The wood chip waste is first mixed into dust-containing air by a blower to form exhaust gas, and the mixed exhaust gas is then transported to the filter cartridge 100. Next, the wood chips are compressed by an auger spiral 300, and the large specific surface area and porous structure of the compressed wood chips are used to absorb dust in the air. The air is discharged outward through the porous structure of the wood chips, thereby achieving the effect of removing dust from the air.

[0038] It should also be noted that in the present invention, the reason why the volume of wood chips in the first area 310 exceeds one half of the volume of the first area 310 is to ensure that the air entering from the air inlet 110 can only pass through the compressed wood chips and then be discharged outward through the air outlet 120, but cannot be discharged from the air outlet 120 through the gap between the auger spiral 300 and the wood chips, so that the air discharged from the air outlet 120 is all adsorbed and filtered by the wood chips.

[0039] It should also be noted that in other embodiments, the staff can also adjust the blowing speed of the blower and the rotation speed of the auger screw 300 so that the volume of wood chips in the first area 310 is dynamically maintained at half the volume of the first area 310, so as to avoid intermittent operation of the auger screw 300 and improve the working efficiency of the auger screw 300.

[0040] In a further embodiment, Figure 4 As shown, a first telescopic tube 410 is fixedly connected to one end of the air inlet 110, and a second telescopic tube 420 is provided to adapt to the vertical movement of the filter cartridge 100 so that the blower and the air inlet 110 are always connected to facilitate stable delivery of exhaust gas into the filter cartridge 100.

[0041] In a further embodiment, a second telescopic tube 420 is fixedly connected to one end of the air outlet 120. The second telescopic tube 420 is also provided to adapt to the vertical movement of the filter cartridge 100 so that the induced draft fan and the air inlet 110 are always connected to facilitate the stable discharge of air out of the filter cartridge 100.

[0042] In a further embodiment, Figure 4 As shown, a distance sensing module 500 is disposed on the support frame 200 , and the distance sensing module 500 is used to detect the distance between the filter cartridge 100 and the support frame 200 , and further detect whether the volume of the wood chips temporarily stored in the first area 310 reaches a preset value.

[0043] When the volume of the wood chips reaches a preset value, the increased weight of the wood chips will press down the filter cartridge 100, causing the filter cartridge 100 to move downward. At this time, the distance between the support frame 200 and the filter cartridge 100 is reduced to a preset value. The distance sensing module 500 detects that the distance between the filter cartridge 100 and the support frame 200 reaches the preset value, thereby sending an electrical signal to the servo motor 720, causing the servo motor 720 to drive the auger screw 300 to rotate.

[0044] In a further embodiment, Figure 4 As shown, a conical guide hopper 600 is provided at one end of the filter cartridge 100 close to the air inlet 110, and the conical guide hopper 600 is provided for guiding the air.

[0045] In a further embodiment, a sliding guide is provided between the filter cartridge 100 and the support frame 200. The sliding guide frame is used to allow the filter cartridge 100 to move only in a vertical direction relative to the support frame 200. The sliding guide is provided to guide the movement of the filter cartridge 100 to prevent the filter cartridge 100 from shifting in a non-vertical direction and causing failure of the distance sensing module 500.

[0046] In a further embodiment, Figure 1As shown, a transparent observation window 140 is inlaid on the peripheral wall of the filter cartridge 100 . The transparent observation window 140 is provided to facilitate the staff to observe the amount of wood chips in the first area 310 and the second area 320 .

[0047] In a further embodiment, Figure 1 As shown, support legs 220 are provided at the four lower corners of the support frame 200 , and the support legs 220 are provided to support the support frame 200 .

[0048] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0049] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
