DETAILED DESCRIPTION

[0057] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be noted that the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0058] See also Figures 1 to 12 , the present invention provides a technical solution: Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, it includes an air inlet pipe 1 for collecting exhaust gas generated above the workstation;

[0059] A feed pipe 2 is used to collect waste or debris generated below the workstation, and the top of the feed pipe 2 is connected to the bottom of the air inlet pipe 1;

[0060] The outer end faces of the air inlet pipe 1 and the feed pipe 2 are both equipped with a filtering mechanism 3, which will filter the introduced exhaust gas and waste materials; by connecting the inclined filter screen 55 to the external induced draft fan and starting the induced draft fan, the induced draft fan will generate suction in the pipe, wherein the air inlet pipe 1 is placed above the cutting plotter, but not too close to avoid the exhaust gas temperature from being too high and causing damage to the pipe, and the feed pipe 2 is placed at the waste outlet station of the cutting plotter. By starting the induced draft fan, airflow will be generated in the air inlet pipe 1 and the feed pipe 2. At this time, the exhaust gas generated by the cutting plotter will be sucked into the air inlet pipe 1, and the waste generated by the cutting plotter will be sucked into the feed pipe 2, thereby playing a role in classifying, ventilating and regulating the debris or odor that affects the working environment generated during the cutting process of the cutting plotter.

[0061] A ventilation mechanism 4 is installed at the end of the filter mechanism 3 away from the air inlet pipe 1. The ventilation mechanism 4 will draw the filtered air and use a rotating unit to improve the connection between the ventilation mechanism 4 and the external induced draft fan;

[0062] The Z-shaped frame 5 has urea and oxalic acid placed inside, which are used for condensation reaction with formaldehyde in the exhaust gas, and is fixedly installed inside the air inlet pipe 1; the Z-shaped frame 5 is provided inside the air inlet pipe 1, and urea is placed in the upper two cavities of the Z-shaped frame 5, and oxalic acid is placed in the bottom cavity. Therefore, a small amount of formaldehyde gas in the exhaust gas will initially come into contact with the urea solution. Because the collected exhaust gas still carries a certain amount of heat, but the heat is not too high to avoid decomposition of formaldehyde and urea, there will be a mixture of formaldehyde and urea in the exhaust gas. Then the formaldehyde and urea mixture will move to the lower cavity of the Z-shaped frame 5 and come into contact with oxalic acid. At this time, oxalic acid will act as a catalyst, causing formaldehyde and urea to undergo condensation reaction and eventually produce urea-formaldehyde resin solid, thereby performing condensation treatment on a small amount of formaldehyde in the exhaust gas and avoiding pollution to the pipeline and the outside air.

[0063] The first retention plate 6 and the second retention plate 7 divide the Z-shaped frame 5 into three cavities, so that the upper two cavities are filled with urea and the bottom cavity is filled with oxalic acid;

[0064] The first retention plate 6 and the second retention plate 7 are both fixedly mounted on the inner cavity of the Z-shaped frame 5.

[0065] The filter mechanism 3 includes a square tube 31, the outer ends of which are fixedly connected to the air inlet pipe 1 and the feed pipe 2 respectively;

[0066] The first filter screen 32 and the second filter screen 33 are used to filter waste and debris, and the filter holes on the surfaces of the two filters are staggered.

[0067] The first filter screen 32 and the second filter screen 33 are both fixedly installed inside the square tube 31;

[0068] The first filter screen 32 and the second filter screen 33 are both inserted into the top of the square tube 31 and extend to the outside. The top of the second filter screen 33 is fixedly connected with a handle 34;

[0069] The plug rod 35 is used to reduce the filtering gap of the first filter screen 32 and is fixedly connected to the top of the first filter screen 32;

[0070] The outer side of the plug rod 35 is fixedly connected to an external plate 36;

[0071] The electric push rod 37 is used to raise and lower the plug rod 35 and is fixedly connected to the top of the square tube 31;

[0072] The top end of the electric push rod 37 is fixedly connected to the external plate 36, and the outer side of the telescopic end of the electric push rod 37 is fixedly connected to the sleeve plate 38;

[0073] The bottom of the sleeve plate 38 is fixedly connected with a compensation rod 39;

[0074] The constant temperature rack 30 is used for cooling the waste gas and waste materials, and is fixedly connected to the bottom end of the compensation rod 39. When there are still a few impurities that have not been filtered by the No. 1 filter 32 and the No. 2 filter 33 and are filtered by the inclined filter 55, these impurities will fall into the trapezoidal frame 56 and form an accumulation. When the impurities accumulate to a certain height, the sensor 57 will sense it, and then the sensor 57 will control the electric push rod 37 to retract, causing the external plate 36 connected to the telescopic end of the electric push rod 37 to move downward with the plug rod 35 until the plug rod 35 is inserted into the interior of the No. 1 filter 32, thereby increasing the filtering effect of the No. 1 filter 32. At the same time, the electric push rod 37 will also move downward with the sleeve plate 38 during the contraction process, wherein the bottom of the sleeve plate 38 is connected to the constant temperature frame 30 through the compensation rod 39, so the constant temperature frame 30 will extend into the interior of the square tube 31, wherein the constant temperature frame 30 is kept constantly cold, thereby playing the role of using cooling to condense water vapor or some gaseous pollutants in the airflow to form larger particles and reduce linearity.

[0075] like Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 and Figure 12 As shown, the ventilation mechanism 4 includes a reducing tube 41, the outer end of which is fixedly connected to the square tube 31, a through hole 42 is formed on the outer side of the reducing tube 41, and a frame 43 is fixedly connected to the bottom of the inner cavity of the reducing tube 41. A motor 44 is fixedly installed inside the frame 43, and the output end of the motor 44 is connected to a rotating shaft 45 through a coupling. The outer side of the rotating shaft 45 is fixedly connected to a connecting rod 46;

[0076] The cleaning sponge 47 is used for all-round cleaning of the inner wall of the pipe and is fixedly connected to the connecting rod 46; the ventilation pipe 48 is fastened to the flange 49 by bolts, and then the motor 44 is started, so that the rotating shaft 45 connected to its output end through a coupling will rotate, and the outer side of the rotating shaft 45 is connected to the connecting rod 46, and the other end of the connecting rod 46 is connected to the cleaning sponge 47, so the cleaning sponge 47 will rotate in a circle in the ventilation pipe 48, thereby cleaning some unfiltered sticky impurities or dust on the inner wall of the ventilation pipe 48.

[0077] The end of the reducer 41 away from the square tube 31 is fixedly connected to the ventilation pipe 48. The end of the ventilation pipe 48 away from the reducer 41 is fastened to a flange 49 by bolts. The flange 49 has a groove 40 formed inside. The outer side of the flange 49 is fixedly connected to a rod seat 401. The center of the rod seat 401 is fixedly connected to a long axis 402.

[0078] The guide blades 403 are used to draw the residual wind that escapes from the through hole 42 and are rotatably connected to the long shaft 402 .

[0079] The outer side of the rotating shaft 45 is fixedly connected to a multi-faceted block 404, and the outer side of the multi-faceted block 404 is fixedly connected to a resetting telescopic rod 405, wherein the resetting telescopic rod 405 has a resetting and retracting function;

[0080] The telescopic ring 406 has the functions of contraction and expansion and is fixedly connected to the resetting telescopic rod 405;

[0081] The outer side of the rotating shaft 45 is extruded and adapted with a bearing 407;

[0082] Telescopic column 408, having telescopic function and fixedly connected to bearing 407;

[0083] The return spring 400 is used to reset the telescopic column 408 and is fixedly connected to the fixed portion of the telescopic column 408;

[0084] The top of the return spring 400 is fixedly connected with a square piece 409, which is fixedly connected to the telescopic end of the telescopic column 408, and the bottom of the square piece 409 is squeezed and adapted to the telescopic ring 406; in addition, as the rotating shaft 45 rotates, the multi-faceted block 404 fixedly connected to the outer side thereof will rotate, wherein the outer side of the multi-faceted block 404 is connected to the reset telescopic rod 405, so the reset telescopic rod 405 will rotate with the telescopic ring 406 fixedly connected to the other end thereof. Because the rotation of the rotating shaft 45 causes the reset telescopic rod 405 to generate centrifugal force, and the telescopic ring 406 connected to the telescopic end of the reset telescopic rod 405 6 will expand outwards and squeeze the square piece 409 upwards, and then the squeezed square piece 409 will move upwards with the telescopic end of the telescopic column 408 and stretch the return spring 400, wherein the telescopic column 408 is provided with a mosaic plate 54 above, so the mosaic plate 54 will be squeezed upwards by the telescopic end of the telescopic column 408, causing the mosaic plate 54 to move upwards along the vertical rail 52 through the slider 53 until it is embedded in the groove body 40, thereby increasing the connection relationship between the ventilation pipe 48 and the flange 49 during the operation of the equipment. At the same time, the faster the rotating shaft 45 rotates, the tighter the ventilation pipe 48 and the flange 49 will be.

[0085] The counterweight 51 is used to balance the forces at both ends of the telescopic column 408 and is fixedly connected to the square piece 409 .

[0086] A vertical rail 52 is fixedly connected to the end surface of the ventilation pipe 48, and a slider 53 is adapted to slide inside the vertical rail 52;

[0087] The interlocking plate 54 is interlocked with the trough body 40 to strengthen the close relationship between the ventilation pipe 48 and the flange 49. The bottom of the interlocking plate 54 is squeezed and fitted with the top of the telescopic column 408.

[0088] An oblique filter screen 55 is fixedly connected to the end of the flange 49 away from the ventilation pipe 48;

[0089] The trapezoidal frame 56 is in a trapezoidal shape that is wide at the top and narrow at the bottom, and is used for secondary filtering of impurities in the airflow;

[0090] The sensor 57 is used to detect whether the impurities inside the trapezoidal frame 56 have accumulated to a certain height, and to control the electric push rod 37 . The sensor 57 is fixedly mounted on the outside of the trapezoidal frame 56 .

[0091] When the present invention is in use: first, the inclined filter 55 is connected to the external induced draft fan and the induced draft fan is started. At this time, the induced draft fan will generate suction in the pipeline, wherein the air inlet pipe 1 is placed at the upper station of the cutting plotter, and the feed pipe 2 is placed at the waste outlet station of the cutting plotter. By starting the induced draft fan, airflow will be generated in the air inlet pipe 1 and the feed pipe 2. At this time, the exhaust gas generated by the cutting plotter will be sucked into the air inlet pipe 1, and the waste generated by the cutting plotter will be sucked into the feed pipe 2. A Z-shaped frame 5 is provided inside the air inlet pipe 1, and urea is placed in the upper two cavities of the Z-shaped frame 5, and oxalic acid is placed in the bottom cavity. Therefore, a small amount of formaldehyde gas in the exhaust gas will initially come into contact with the urea solution. At this time, there will be a mixed solution of formaldehyde and urea in the exhaust gas. Then, the formaldehyde and urea mixed gas will move to the lower cavity of the Z-shaped frame 5 and come into contact with oxalic acid. At this time, oxalic acid will act as a catalyst, causing a condensation reaction between formaldehyde and urea, and ultimately producing a urea-formaldehyde resin solid with relatively low toxicity.

[0092] The waste material entering the feed pipe 2 will be filtered by the No. 1 filter 32 and the No. 2 filter 33 in turn, and then the filtered gas will enter the reducer 41, wherein the reducer 41 has a through hole 42 on its surface. At this time, a small amount of peripheral residual wind will be blown out through the through hole 42, and the guide blade 403 is facing the through hole 42, so the guide blade 403 will be blown by the residual wind and rotate. At this time, the guide blade 403 will draw the surrounding airflow in, causing the residual waste gas that has not been inhaled outside the pipe to be discharged externally.

[0093] The ventilation pipe 48 is fastened to the flange 49 by bolts. Then the motor 44 is started, so that the rotating shaft 45 connected to its output end through a coupling will rotate. The outer side of the rotating shaft 45 is connected to the connecting rod 46, and the other end of the connecting rod 46 is connected to the cleaning sponge 47. Therefore, the cleaning sponge 47 will rotate in a circle in the ventilation pipe 48 and clean the impurities or dust adhering to the inner wall of the ventilation pipe 48. In addition, as the rotating shaft 45 rotates, the multi-faceted block 404 fixedly connected to its outer side will rotate, wherein the outer side of the multi-faceted block 404 is connected to the reset telescopic rod 405, so the reset telescopic rod 405 will rotate together with the telescopic ring 406 fixedly connected to its other end. Because the rotation of the rotating shaft 45 causes the reset telescopic rod 405 to generate centrifugal force, the telescopic ring 406 connected to the telescopic end of the reset telescopic rod 405 will expand outward and squeeze the square piece 409 upward. Then, the squeezed square piece 409 will move upward with the telescopic end of the telescopic column 408 and stretch the reset spring 400. A mosaic plate 54 is provided above the telescopic column 408. Therefore, the mosaic plate 54 will be squeezed upward by the telescopic end of the telescopic column 408, causing the mosaic plate 54 to move upward along the vertical rail 52 through the slider 53 until it is embedded in the slot body 40.

[0094] When there are still a few impurities that have not been filtered by the No. 1 filter 32 and the No. 2 filter 33 and are filtered by the inclined filter 55, these impurities will fall into the trapezoidal frame 56 and form a pile. When the impurities accumulate to a certain height, the sensor 57 will sense it, and then the sensor 57 will control the electric push rod 37 to retract, causing the external plate 36 connected to the telescopic end of the electric push rod 37 to move downward with the plug rod 35 until the plug rod 35 is inserted into the interior of the No. 1 filter 32 to increase the filtering effect of the No. 1 filter 32. At the same time, the electric push rod 37 will also move downward with the sleeve plate 38 during the contraction process, and the bottom of the sleeve plate 38 is connected to the constant temperature rack 30 through the compensation rod 39, so the constant temperature rack 30 will extend into the interior of the square tube 31 and perform cooling treatment.

[0095] The above embodiments are only preferred embodiments of the present invention and cannot be used to limit the scope of protection of the present invention. Various changes made by ordinary technicians in this field based on the above concepts without creative work fall within the scope of protection of the present invention.
