Description

Technical Field

[0001] The present invention relates to the technical field of waste gas treatment, and in particular to a waste gas treatment device based on industrial machinery. Background Art

[0002] During the operation of industrial machinery, the combustion of the internal combustion engine of the machinery will produce exhaust gas. These exhaust gases include: carbon dioxide, carbon disulfide, hydrogen sulfide, fluoride, nitrogen oxides, chlorine, hydrogen chloride, carbon monoxide, sulfuric acid (mist), lead and mercury, beryllium, smoke and other substances. These gases are directly discharged into the atmosphere and will pollute the air. These substances enter the human body through the respiratory tract through different pathways. Some of them directly cause harm, while others have an accumulation effect, which will more seriously endanger human health.

[0003] Usually during the waste gas treatment process, the waste gas will be introduced into a closed container for filtration or adsorption treatment.

[0036] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution 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 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 creative work are within the scope of protection of the present invention.

[0037] The present invention will be further described below in conjunction with the embodiments.

[0038] Embodiment: An exhaust gas treatment device based on industrial machinery, such as Figure 1 - Figure 3 As shown, it comprises a base 1, a barrel body 11 is fixedly installed on the top of the base 1, an air inlet pipe 12 and an air outlet pipe 13 are respectively arranged on both sides of the barrel body 11, and a barrel cover 15 is arranged on the top of the barrel body 11; a plurality of heat sinks 14 are fixedly installed on the outside of the barrel body 11;

[0039] The cooling assembly 3 is rotatably installed inside the barrel body 11, and is used for cooling and filtering the gas introduced into the barrel body 11. It includes a rotating barrel 31 rotatably installed inside the barrel body 11, and a spiral blade 32 is fixedly installed on the outer side of the rotating barrel 31. The spiral blade 32 is used to separate the space between the barrel body 11 and the rotating barrel 31, and guide the exhaust gas to spiral upward.

[0040] The adsorption rack 4 is threadably mounted inside the rotating barrel 31 and is used to adsorb harmful substances in the passing exhaust gas. The adsorption rack 4 is provided with a driving component for driving the adsorption rack 4 to spirally ascend.

[0041] In the present invention, by arranging a cooling component 3 inside the barrel body 11, when treating the exhaust gas generated by the industrial machinery, the exhaust gas is first introduced into the barrel body 11 from the air inlet pipe 12, and then the exhaust gas drifts upward along the spiral blades 32. When the exhaust gas drifts upward along the spiral blades 32, heat exchange occurs with the spiral blades 32 and the inner wall of the barrel body 11, so that the gas in a high temperature state can be cooled, and the harmful substances in a gasified state can be liquefied and retained on the spiral blades 32. Then, the cooled exhaust gas moves downward from the top of the barrel body 11 to the inside of the rotating barrel 31 under the action of air pressure, and is adsorbed inside the rotating barrel 31. Finally, the exhaust gas is discharged from the barrel body 11 from the exhaust pipe 13.

[0042] It should be noted that the liquefied harmful substances remain on the spiral blades 32. When accumulated to a certain extent, they can flow downward along the spiral blades 32 to the bottom of the barrel 11, so that the harmful substances can be conveniently collected and uniformly processed.

[0043] Furthermore, if Figure 3 As shown, a sealing plate 33 is fixedly installed on the outer side of the rotating barrel 31. The sealing plate 33 is in a circular ring shape when projected from a top view. The sealing plate 33 is located above the spiral blade 32. A filter screen 34 for filtering exhaust gas is provided on the sealing plate 33.

[0044] Furthermore, if Figure 3 , Figure 4 As shown, multiple groups of guide plates 35 are vertically installed inside the rotating barrel 31, and the multiple groups of guide plates 35 are distributed in a circular shape inside the rotating barrel 31. Spiral guide grooves 3501 are provided on the multiple groups of guide plates 35. The adsorption frame 4 includes multiple filter discs 42 distributed at intervals up and down, and the outer side of the filter disc 42 is fixedly installed with a spiral protrusion 43. The spiral protrusion 43 on the outer side of the filter disc 42 is used to threadably cooperate with the spiral guide groove 3501.

[0045] Among them, by installing the adsorption frame 4 on the internal thread of the rotating barrel 31, when the adsorption material on the adsorption frame 4 needs to be replaced, the adsorption frame 4 can be driven to move upward as a whole by rotating the adsorption frame 4, so that the adsorption frame 4 can slide out of the barrel body 11 as a whole, and the adsorption material on the adsorption frame 4 can be conveniently replaced at this time.

[0046] Among them, by setting a guide plate 35 and setting a spiral guide groove 3501 on the guide plate 35 that threadably cooperates with the spiral protrusion 43, the friction between the spiral protrusion 43 on the outside of the adsorption frame 4 and the inner wall of the spiral guide groove 3501 can be reduced, ensuring that the static friction force that needs to be overcome for the adsorption frame 4 to rotate is smaller than the static friction force that needs to be overcome for the rotating barrel 31 and the barrel body 11 to rotate.

[0047] Furthermore, if Figure 4 As shown, a fixed plate 36 is fixedly installed inside the barrel body 11, and the rotating barrel 31 is rotatably installed on the fixed plate 36. One end of the air outlet pipe 13 passes through the fixed plate 36 and is connected to the inside of the rotating barrel 31. One end of the air inlet pipe 12 passes through the barrel body 11 and extends between the barrel body 11 and the rotating barrel 31.

[0048] When the exhaust gas is introduced, the exhaust gas first enters the space between the barrel body 11 and the rotating barrel 31 from the air inlet pipe 12, then bypasses the outer wall of the rotating barrel 31 and enters the interior of the rotating barrel 31, and enters the exhaust pipe 13 from the bottom of the rotating barrel 31, and finally is discharged from the exhaust pipe 13.

[0049] Furthermore, if Figure 3 , Figure 4 As shown, the driving assembly includes a coaxially arranged rotating shaft 41 and a transmission shaft 44, the rotating shaft 41 passes through a plurality of filter discs 42 respectively and is fixedly connected to the filter discs 42, the upper end of the transmission shaft 44 extends into the rotating shaft 41 and is slidably connected to the rotating shaft 41 up and down, the lower end of the transmission shaft 44 rotates through the fixed disc 36 and the barrel body 11 respectively, and the lower end of the transmission shaft 44 is fixedly installed with a driving gear 45.

[0050] Among them, by sliding the transmission shaft 44 up and down under the rotating shaft 41, when the rotating barrel 31 is driven to rotate and move upward, the rotating shaft 41 can move upward synchronously, and the transmission shaft 44 can drive the rotating shaft 41 to continue to rotate; in addition, the barrel cover 15 is rotatably installed above the rotating shaft 41. When the rotating shaft 41 moves upward with the adsorption frame 4, the top of the rotating shaft 41 pushes the barrel cover 15 to move upward, and naturally opens the top of the barrel body 11.

[0051] Furthermore, if Figure 5 , Figure 6 As shown, it also includes a cleaning box 2, a mounting through hole 101 is provided on one side of the outer circumferential surface of the barrel body 11, a cleaning box 2 is provided on the outer side of the mounting through hole 101, a sliding through hole that penetrates the mounting through hole 101 is provided on the cleaning box 2, a sliding frame 21 is slidably installed up and down inside the cleaning box 2, a cleaning piece 22 is slidably installed on the sliding frame 21, and the cleaning piece 22 passes through the mounting through hole 101 and extends into the barrel body 11 to clean the surface of the spiral blade 32.

[0052] By providing the cleaning box 2 , when it is necessary to clean the critical substances on the surface of the spiral blade 32 , the cleaning piece 22 can be conveniently extended into the interior of the barrel body 11 to clean the surface of the spiral blade 32 .

[0053] Furthermore, if Figure 7 , Figure 8 As shown, the sliding frame 21 includes a U-shaped support frame 211, the opening direction of the U-shaped support frame 211 is toward the end away from the barrel body 11, and the cleaning member 22 includes a sliding plate 221, and the sliding plate 221 is slidably installed inside the U-shaped support frame 211. The sliding plate 221 is provided with an upper and lower set of brush plates 222 at the end facing the barrel body 11, and the end surfaces of the two sets of brush plates 222 facing each other are provided with brushes 223. When cleaning the spiral blade 32, the upper and lower sets of brush plates 222 are respectively located above and below the spiral blade 32.

[0054] Among them, by setting up two sets of upper and lower brush plates 222, in the process of cleaning the spiral blade 32, the two sets of brush plates 222 can be respectively stuck above and below the spiral blade 32, and then the rotating shaft 41 is driven in reverse to rotate, so that the rotating shaft 41 drives the rotating barrel 31 to rotate in the opposite direction, and the spiral blade 32 rotates. When the spiral blade 32 rotates, the upper and lower sets of brush plates 222 can be driven to slide up and down. In the process of the upper and lower sets of brush plates 222 sliding up and down, the cleaning position of the brush plate 222 on the spiral blade 32 also changes. When the spiral blade 32 moves the brush plate 222 from the highest point to the lowest point, the harmful substances attached to the spiral blade 32 can be pushed from the top of the spiral blade 32 to the bottom of the spiral blade 32, and the accumulated liquid harmful substances can drip on the bottom plate of the barrel body 11 for unified collection.

[0055] It should be noted that the rotating shaft 41 drives the rotating barrel 31 to rotate in the opposite direction (i.e. Figure 3 When the spiral blade 32 rotates, the bottom of the adsorption rack 4 abuts against the bottom of the rotating barrel 31, so that the adsorption rack 4 and the rotating barrel 31 do not rotate relative to each other. Figure 3 The rotating shaft 41 will drive the adsorption frame 4 to rotate only when the rotation direction is clockwise.

[0056] In addition, a guide rod 212 is fixedly installed inside the U-shaped support frame 211 . The guide rod 212 passes through the sliding plate 221 , and the guide rod 212 guides the sliding of the sliding plate 221 .

[0057] Furthermore, if Figure 6As shown, guide rails 24 are fixedly installed on the inner walls of the cleaning box 2 on both sides of the sliding through hole, and the U-shaped support frame 211 is slidably connected to the guide rails 24 up and down. Two upper and lower groups of elastic dustproof cloths 23 are also provided at the sliding through hole, and one end of the two groups of elastic dustproof cloths 23 are respectively connected to the upper and lower inner walls of the sliding through hole, and the other ends of the two groups of elastic dustproof cloths 23 are respectively connected to the upper and lower ends of the U-shaped support frame 211.

[0058] Among them, by arranging an elastic dustproof cloth 23 at the sliding through hole, it can be prevented that dust in the exhaust gas is scattered from the sliding through hole to the inside of the cleaning box 2 during the exhaust gas treatment process, and the inside of the cleaning box 2 can be kept clean.

[0059] Working principle: When the adsorption material on the adsorption rack 4 needs to be replaced, the drive gear 45 is driven by an external motor to rotate forward (i.e. Figure 3 The rotation of the rotating shaft 41 will drive the adsorption rack 4 on the outside to rotate. When the adsorption rack 4 rotates, the outer side of the adsorption rack 4 is threadedly matched with the guide plate 35 on the inner wall of the rotating barrel 31, so that the adsorption rack 4 rotates and moves upward at the same time, and the adsorption rack 4 can be conveniently spirally slid out of the barrel body 11 as a whole to expose the multi-layer filter disc 42 on the adsorption rack 4, and then the old adsorption material (for example, activated carbon) on the filter disc 42 can be removed and replaced with a new adsorption material;

[0060] When the spiral blade 32 needs to be cleaned, the driving gear 45 is driven by an external motor to rotate in the opposite direction, and the rotating shaft 41 above the driving gear 45 drives the outer adsorption frame 4 to rotate, and the rotating barrel 31 outside the adsorption frame 4 rotates synchronously with the adsorption frame 4, so that the spiral blade 32 can drive the harmful substances or smoke attached to the inner wall of the barrel body 11 to move downward. In addition, before the spiral blade 32 rotates, the cleaning piece 22 inside the cleaning box 2 on the side of the barrel body 11 is slid to the top, and the brush plates 222 of the cleaning piece 22 are respectively stuck on the upper and lower end surfaces of the spiral blade 32, and then as the spiral blade 32 rotates, the spiral blade 32 drives the cleaning piece 22 to slide downward. In the process of the cleaning piece 22 sliding downward, the brush plate 222 of the cleaning piece 22 is always attached to the outer side of the spiral blade 32, so that different positions on the spiral blade 32 can be cleaned, and the harmful substances or dust deposited on the spiral blade 32 are pushed to move downward along the spiral blade 32.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
