[0001] The invention belongs to the technical field of wood processing dust removal, and in particular relates to a multi-stage dust removal device for wood processing. Background Art

[0002] In wood processing workshops, a large amount of wood dust is generated during the process of cutting, planing, sawing and crushing wood. This dust not only affects the health of operators, but may also cause safety problems such as fire. Therefore, taking effective dust removal measures is crucial to improving the working environment and ensuring employee safety. At present, many wood mills have installed dust removal devices at the outlets of chippers, planers, saws and crushers to reduce the spread of dust.

DETAILED DESCRIPTION

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0019] The structure of the present invention is described in detail below in conjunction with the accompanying drawings.

[0020] See also Figures 1 to 10 A multi-stage dust removal device for wood processing provided by an embodiment of the present invention comprises a dust removal shell 1, a base is fixedly connected to the bottom of the dust removal shell 1, a plurality of first air outlets 2 are opened on the top of the dust removal shell 1, a filter tube 3 is installed in the dust removal shell 1, a plurality of first connecting rods 4 are fixedly connected between the filter tube 3 and the dust removal shell 1, an exhaust disk 5 is sleeved on the outer surface of the filter tube 3 and fixedly connected to the filter tube 3; an air inlet pipe 6 is installed on the side wall of the filter tube 3, and the air inlet pipe 6 is connected to the filter tube 3; an air outlet piece is installed in the exhaust disk 5, and the bottom of the air outlet piece passes through the exhaust disk 5 and extends into the dust removal shell 1; a gas separation component is installed on the upper wall of the dust removal shell 1.

[0021] The above scheme is adopted: when in use, when the dust generated during the processing of wood flows out from the discharge port of the processing machinery into the outside air, the external air pump will pass the dust gas into the filter tube 3 through the air inlet pipe 6, and then the dust gas will enter the exhaust plate 5 through the filter tube 3, and then the dust-containing gas in the exhaust plate 5 will enter the dust removal shell 1 through the air outlet piece. At this time, the gas separation component rotates, and during this process, liquid will be sprayed into the dust removal shell 1 through the gas separation component, so as to spray and remove the dust-containing gas in the dust removal shell 1, so as to separate the gas and dust, and the dust-containing gas after spraying and dust removal will be discharged to the outside through the first air outlet 2.

[0022] It should be noted that: first, the liquid at the bottom of the dust removal housing 1 is water. Second, the liquid sprayed out by the gas separation component can be water, and can also be replaced with a liquid that has a separation effect on dust-containing gas according to actual needs. Third, an external hose can be used to use a pump body to inject liquid into the dust removal housing 1.

[0023] Furthermore, the gas separation component includes a first rotating shaft 7, one end of which is located in the dust removal shell 1, and the other end of the first rotating shaft 7 extends to the outside of the dust removal shell 1; a plurality of first hollow cavity tubes 8 are fixedly connected to the outer surface of the first rotating shaft 7 close to the upper wall of the dust removal shell 1, and a plurality of first liquid outlet holes 9 are opened on the outer surface of the first hollow cavity tube 8; a first shielding tube 10 is slidably connected to the first hollow cavity tube 8, and a first spring 11 is fixedly connected between the first shielding tube 10 and the first hollow cavity tube 8.

[0024] Furthermore, a first channel 12 is opened in the first rotating shaft 7, and the first cavity tubes 8 are all connected to the first channel 12; a water tank 13 is installed on the upper side of the dust removal shell 1, and the first channel 12 is connected to the water tank 13, and the water tank 13 is located between the multiple first air outlets 2.

[0025] The above scheme is adopted: when in use, when the dust-containing gas rises to the upper end of the dust removal shell 1, the first rotating shaft 7 drives the first cavity tube 8 and the first shielding tube 10 to rotate, and the centrifugal force is used to make the first shielding tube 10 drive the first spring 11 to gradually extend and no longer block the first liquid outlet 9. At this time, the liquid in the water tank 13 enters the first cavity tube 8 through the first channel 12, and is sprayed into the dust removal shell 1 through the first liquid outlet 9, so as to spray and remove dust from the dust-containing gas. The sliding of the first shielding tube 10 on the first cavity tube 8 extends the length of the first cavity tube 8, thereby increasing the rotation range and improving the dust removal efficiency.

[0026] It should be noted that when the rotation range of the first cavity tube 8 and the first shielding tube 10 needs to be adjusted, the rotation speed of the first rotating shaft 7 can be increased, and the rotation speed of the first rotating shaft 7 is adjusted according to specific circumstances.

[0027] Furthermore, a plurality of drain pipes 14 are installed on one side of the bottom of the dust removal shell 1 close to the base, and a first blocking block 15 is slidably connected inside the drain pipe 14; a second spring 16 is installed inside the drain pipe 14, one end of the second spring 16 is fixedly connected to the inner wall of the drain pipe 14, and the other end of the second spring 16 is fixedly connected to the first blocking block 15, and a plurality of second liquid outlet holes 17 are opened on the outer surface of the drain pipe 14.

[0028] Adopting the above-mentioned scheme: when in use, when it is necessary to discharge the liquid in the dust removal shell 1, the water pressure inside the dust removal shell 1 gradually increases, and the water pressure pushes the first blocking block 15 to slide toward the side wall of the filter tube 3 in the drain pipe 14, while compressing the second spring 16. The continuous movement of the first blocking block 15 eventually causes the drain pipe 14 to be opened, and the liquid is discharged to the outside through the second liquid outlet 17.

[0029] It should be noted that a one-way valve may be installed in the drain pipe 14 to control the outflow of liquid.

[0030] Furthermore, an elastic airbag 18 is fixedly connected between the filter tube 3 and the exhaust plate 5 , and a plurality of first flexible hoses 19 are installed between the elastic airbag 18 and the water storage tank 13 .

[0031] The above scheme is adopted: when in use, when the dust-containing gas flow in the air inlet pipe 6 increases and enters the exhaust disk 5 through the filter tube 3, the air pressure in the exhaust disk 5 increases, thereby compressing the elastic airbag 18. The compressed elastic airbag 18 transports its internal gas to the water tank 13 through the first flexible hose 19, prompting the liquid to flow into the first channel 12. Subsequently, the liquid enters the first cavity tube 8 through the first channel 12 and is sprayed into the dust removal shell 1, spraying and dust reduction treatment is performed on the rising dust-containing gas, thereby achieving re-purification of the dust-containing gas that has not been fully purified.

[0032] When the gas in the elastic airbag 18 squeezes out the liquid in the water tank 13, the external water inlet mechanism replenishes the liquid into the water tank 13. While replenishing the liquid, the liquid squeezes the gas in the water tank 13 into the elastic airbag 18, thereby achieving the resetting of the elastic airbag 18.

[0033] It should be noted that: a float valve may be provided inside the water storage tank 13, and water may be automatically replenished when it is detected that the liquid in the water storage tank 13 is lower than a preset liquid level.

[0034] Furthermore, the air outlet component includes an air outlet head 20, which is located in the exhaust disk 5. A plurality of air holes 21 are provided on the outer surface of the air outlet head 20. Elastic blocking blocks 22 are slidably connected to the air holes 21. A first air outlet pipe 23 is fixedly connected to the lower side of the air outlet head 20. The first air outlet pipe 23 is connected to the air outlet head 20, and the other end of the first air outlet pipe 23 extends into the dust removal shell 1.

[0035] The above solution is adopted: when in use, when the dust-containing gas inside the exhaust disk 5 needs to enter the dust removal housing 1, the elastic block 22 slides out from one end of the air hole 21 under the action of the gas, opens the exhaust channel, and allows the gas to enter the first air outlet pipe 23 through the air outlet head 20 and be discharged to the dust removal housing 1. On the contrary, when there is no gas in the exhaust disk 5, the elastic block 22 uses its own elasticity to reset and re-block the air hole 21 to prevent water in the dust removal housing 1 from entering the exhaust disk 5 through the air hole 21.

[0036] It should be noted that: first, the gas outlet head 20 can be rotatably connected to the first gas outlet pipe 23, so that the gas outlet head 20 can discharge dust gas from different angles inside the exhaust plate 5 when rotating. Second, a plurality of circular holes are also provided in the lower part of the first gas outlet pipe 23, so that when the gas containing dust enters the first gas outlet pipe 23, it can enter the dust removal housing through the circular holes.

[0037] Furthermore, a screen 24 is installed in the filter tube 3 , and a plurality of cleaning brushes 25 are fixedly connected to a side of the outer surface of the first rotating shaft 7 close to the screen 24 .

[0038] Furthermore, a dust outlet is provided on one side of the outer surface of the filter tube 3 close to the screen 24 , and the dust outlet is connected to the filter tube 3 . A material receiving box 26 that can be connected to the dust outlet is installed on the outer wall of the filter tube 3 .

[0039] The above scheme is adopted: when in use, after the dust-containing gas enters the filter tube 3 through the air inlet pipe 6, it first passes through the screen 24 to filter out large particles of dust, thereby reducing the burden of subsequent water adsorption and spraying treatment. At the same time, the rotating first shaft 7 drives the cleaning brush 25 to rotate, cleans the screen 24, and uses centrifugal force to push the impurities on the screen 24 to the dust outlet, and then enters the connected material collection box 26, effectively preventing the screen 24 from being blocked, thereby achieving the effect of multi-stage dust removal and improving the dust removal efficiency.

[0040] Furthermore, a motor 27 is installed at one end of the first rotating shaft 7 , and an output end of the motor 27 is fixedly connected to the first rotating shaft 7 .

[0041] With the above solution, when the first rotating shaft 7 needs to rotate, the output end of the motor 27 drives the first rotating shaft 7 to rotate.

[0042] Furthermore, the cleaning brush 25 is arc-shaped.

[0043] Working principle of the present invention: When the dust generated during wood processing is discharged from the discharge port of the equipment to the outside air, the external air pump draws the dust-containing gas into the filter tube 3 through the air inlet pipe 6. The gas then passes through the filter tube 3 and enters the exhaust plate 5. The dust-containing gas in the exhaust plate 5 is introduced into the dust removal housing 1 through the gas outlet. At this stage, the gas separation component starts to rotate, and liquid is sprayed into the dust removal housing 1 to spray and remove dust from the dust-containing gas, thereby separating the gas from the dust. The dust-containing gas that has completed the spray dust removal is finally discharged to the outside through the first gas outlet 2.
