[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] Embodiment 1, as Figure 1 , Figure 2 and Figure 7 As shown, a waste gas treatment device for tape production includes a main body 1, a rotating component 2 is arranged inside the main body 1, and a filter component 3 is arranged on the outer surface of the rotating component 2, which is the first step in treating waste gas from tape production. It can effectively intercept large particles in the waste gas to prevent them from entering the subsequent treatment stage and causing wear or blockage to the equipment, and enhance its cleaning ability and extend its service life. A spray component 4 is arranged on the upper side of the filter component 3, which is the second step in treating waste gas from tape production. Through the diagonal spray layout, it is ensured that the packing layer 46 is in full contact with the spray liquid. Three biological purification components 5 are arranged on the upper side of the spray component 4, which is the third step in treating waste gas from tape production. Microorganisms are used to degrade organic matter in the waste gas. Scraping components 6 are respectively arranged at the lower ends of the three biological purification components 5 to avoid blockage. Oxygen injection components 7 are arranged at the upper ends of the three biological purification components 5, which can promote the activity of microorganisms and improve the efficiency of biological purification.

[0035] In this embodiment, in the process of introducing, filtering, spraying and then treating the waste gas from the production of tapes by the present invention, the rotating component 2 penetrates the filter component 3, the spray component 4, the biological purification component 5, the scraping component 6 and the oxygen injection component 7. First, in the particle filtering step, the filter component 3 is used for automatic cleaning to prevent blockage. Then, in the spraying step, the diagonal layout is used to ensure that the waste gas from the production of tapes is fully in contact with the spray liquid, thereby effectively removing the pollution in the waste gas. Finally, while the waste gas from the production of tapes is biologically purified through the biological rotary disk, the scraping component 6 and the oxygen injection component 7 are used to clean and supply oxygen to the biological purification component 5, thereby extending the service life of the biological purification component 5, forming a complete waste gas treatment chain for the production of tapes, reducing human intervention and manual operation, improving treatment efficiency and stability, and realizing efficient treatment of waste gas.

[0036] Embodiment 2: Based on Embodiment 1, this embodiment is to achieve the effect of automatic dust cleaning during the preliminary filtration of waste gas particulate matter in the production of adhesive tape.

[0037] For details, see Figure 1-5 The main body 1 includes a tank body 11 , an air inlet 12 is arranged on the left side of the tank body 11 , a drain outlet 13 is arranged at the lower end of the tank body 11 , and a supporting leg 14 is arranged at the lower end of the tank body 11 .

[0038] The rotating assembly 2 includes a fixed seat 21 fixedly connected to the outer surface of the tank body 11, a motor 22 is fixedly installed on the upper end of the fixed seat 21, a rotating rod 25 is rotatably connected to the inside of the tank body 11, the bottom end of the rotating rod 25 is fixedly connected to a rotating seat 251, and the top end of the rotating rod 25 is rotatably connected to a fixed frame 252. The rotating rod 25 runs through the inside of the main body 1 and always keeps rotating. The lower end of the rotating seat 251 is rotatably connected to the tank body 11, and the output end of the motor 22 and the lower part of the outer surface of the rotating rod 25 are fixedly connected to a bevel gear transmission group 23. The bevel gear transmission group 23 is composed of two mutually meshing bevel gears to realize the conversion of the rotation direction.

[0039] For further information, see Figure 3-5 The filter assembly 3 includes two limit frames 31 fixedly connected to the inner surface of the tank body 11, and the two limit frames 31 are movably connected to a filter plate 32 on one side close to each other. The limit frames 31 can limit the filter plate 32 so that it can shake back and forth between the two. The outer surface of the filter plate 32 is slidably connected to the inner surface of the tank body 11, and the rotating rod 25 passes through the outer surface of the filter plate 32 and is movably connected to the filter plate 32. The filter plate 32 will not be driven to rotate by the rotating rod 25.

[0040] Furthermore, a fixing plate 312 is fixedly connected to the inner surface of the tank body 11 and located on the upper side of the filter plate 32. A support block 37 is fixedly connected to the lower end of the fixing plate 312, which can limit the rotation shaft 35 and the eccentric ring 36. The inner surface of the support block 37 is rotatably connected to the rotation shaft 35. The rear end of the rotation shaft 35 and the middle and lower part of the outer surface of the rotating rod 25 are fixedly connected to a bevel gear transmission group 2 33. The bevel gear transmission group 2 33 is composed of two mutually meshing bevel gears to realize the conversion of the rotation direction. The front side of the rotating shaft 35 is fixedly connected with an eccentric ring 36, and the inner surface of the eccentric ring 36 is slidably connected with a movable block 38. The rotation of the eccentric ring 36 can drive the movable block 38 to move up and down continuously. The front end of the movable block 38 is fixedly connected with a connecting block 39, and the lower surface of the connecting block 39 is fixedly connected with a connecting rod 310. The upper end of the connecting block 39 is fixedly connected with a telescopic rod 3101. The upper end of the telescopic rod 3101 is fixedly connected to the lower end of the fixed plate 312. The outer surface of the telescopic rod 3101 is sleeved with a spring. 311, the upper end of the spring 311 is fixedly connected to the fixed plate 312, and the lower end of the spring 311 is fixedly connected to the connecting block 39. The spring 311 can provide buffering and reset for the connecting block 39, ensuring that when the lower side of the inner surface of the eccentric ring 36 is separated from the movable block 38, the movable block 38 loses the limit of the eccentric ring 36 and will open downward due to the elastic force of the spring 311, and fit with the lower side of the eccentric ring 36 again. The existence of the spring 311 prevents the telescopic rod 3101 from being telescopic after long-term use. Insensitivity occurs, so that when the eccentric ring 36 rotates, it can continuously drive the movable block 38, the connecting block 39, the connecting rod 310 and the filter plate 32 to bounce up and down. The lower end of the connecting rod 310 is fixedly connected to the limit block 3102, which is convenient for limiting the filter plate 32, so that the connecting rod 310 drives the limit block 3102 and the filter plate 32 to move together when extending and retracting. The outer surface of the telescopic rod 3101 is slidably connected to the filter plate 32, and the upper end of the limit block 3102 is movably connected to the lower end of the filter plate 32.

[0041] The waste gas generated by the production of adhesive tape is often mixed with some particles. The waste gas enters the tank 11 from the air inlet 12 and first passes through the filter plate 32 to filter the larger particles in the waste gas from the production of adhesive tape. The starting motor 22 drives the bevel gear transmission group 1 23 to rotate, so that the bevel gear transmission group 1 23 drives the rotating rod 25 to rotate. The rotation of the rotating rod 25 drives the bevel gear transmission group 2 33 to rotate, so that the rotating shaft 35 and the eccentric ring 36 rotate at the same time. The eccentric ring 36 will continuously rotate when rotating. The movable block 38 and the connecting block 39 are lifted upwards. At the moment when the lower side of the inner surface of the eccentric ring 36 is separated from the movable block 38, the movable block 38 loses the limit of the eccentric ring 36 and opens downwards due to the elastic force of the spring 1 311, and fits with the lower side of the eccentric ring 36 again, so that the eccentric ring 36 can continuously drive the movable block 38, the connecting block 39, the connecting rod 310 and the filter plate 32 to bounce up and down when rotating, thereby shaking away the particles and impurities filtered on the surface of the filter plate 32.

[0042] Therefore, this solution intercepts large particles in the waste gas produced by the tape through the cooperation between the rotating component 2 and the filtering component 3, while realizing the automatic cleaning function of the filter plate 32, avoiding the cumbersome and inefficient problems of traditional manual cleaning. By continuous shaking, the particles on the surface of the filter plate 32 can be easily shaken off, preventing blockage and extending the service life of the filter plate 32.

[0043] Embodiment 3: This embodiment is based on embodiments 1 and 2, and is for achieving the effect of fully purifying and filtering the waste gas produced by the adhesive tape.

[0044] For details, see Figure 2 , Figure 6 and Figure 7 The spray assembly 4 includes a through slot 41 opened on the left side of the upper end of the fixed plate 312, and the exhaust gas can only flow upward through the through slot 41. The upper end of the fixed plate 312 is fixedly connected to a separation plate 42. The outer surface of the rotating rod 25 passes through the separation plate 42 and is rotatably connected to the separation plate 42. The outer surface of the rotating rod 25 and the upper side of the separation plate 42 are fixedly connected to a packing layer 46, which can filter and purify the exhaust gas and is driven by the rotating rod 25 to rotate. The lower surface of the packing layer 46 is rotatably connected to the separation plate 42. The inner surface of the main body 1 and the inner surface of the main body 1 are fixedly connected to the separation plate 42. A spray pipe 1 43 is provided on the right side of the separation plate 42, and a spray pipe 2 44 is provided on the surface of the main body 1 and on the upper left side of the packing layer 46. The spray pipe 1 43 and the spray pipe 2 44 are arranged in a diagonal spraying layout, thereby avoiding a spraying blind area and ensuring comprehensive treatment of the exhaust gas. At the same time, the diagonal design will not cause excessive scouring and deformation of the packing layer 46. The outer sides of the spray pipe 1 43 and the spray pipe 2 44 are fixedly connected with a connecting box 45, the side surface of the connecting box 45 is fixedly connected to the main body 1, and the connecting box 45 is connected to an external water source.

[0045] The spray pipe 1 43 and the spray pipe 2 44 mentioned above are key parts of the waste gas treatment spray tower device. The waste gas generated in the tape production process often contains some soluble gases. By spraying washing liquid in contact with the waste gas, the principles of physical dissolution and chemical absorption are utilized to dissolve or absorb these soluble gases and particulate matter into the washing liquid, thereby achieving waste gas purification and improving the removal efficiency of pollutants. This belongs to the prior art and will not be elaborated in detail in the present invention.

[0046] For further information, see Figure 7 The biological purification component 5 includes a rotating plate 52 fixedly connected to the middle and upper part of the outer surface of the rotating rod 25, and a biological membrane 53 is arranged on the upper end of the rotating plate 52.

[0047] Waste gas generated during the production of adhesive tapes, such as triphenyl, ethyl acetate and other organic substances, are the main pollutants. Biofilm 53 can use oxygen to degrade these organic substances into harmless substances, such as carbon dioxide and water, through the microorganisms attached to its surface. In this process, the metabolic activities of microorganisms play a key role. They can transform harmful substances in waste gas, thereby reducing pollution to the environment.

[0048] The biofilm 53 mentioned above belongs to the prior art, and the working principle is based on the formation of the biofilm 53 and the metabolic activity of microorganisms. In the process of purifying waste gas by the biological turntable, a layer of biofilm 53 will first be formed on the surface of the rotating plate 52 by artificial or natural methods. When the waste gas passes through the biofilm 53, the pollutants in the waste gas will be adsorbed and absorbed by the biofilm 53. Under aerobic conditions, the microorganisms use the catalytic action of biological enzymes to oxidize and decompose organic matter, and remove the waste gas generated in the metabolic process. This process forms a continuous cycle of adsorption, oxidation decomposition and oxygen absorption, thereby achieving the purification of waste gas. The device is mainly composed of a turntable, a contact reaction tank, a rotating shaft and a driving device, so the biofilm 53 mentioned above is a conventional design of the prior art and is not elaborated in detail in the present invention.

[0049] When the waste gas needs to be sprayed and filtered, the external water source cooperates with the connecting box 45, the spray pipe 2 44 and the spray pipe 1 43 to spray the packing layer 46. During the spraying process, the packing layer 46 is rotating, and the waste gas can only flow upward through the through groove 41. The packing layer 46 greatly increases the contact area between the waste gas and the spray liquid, so that the harmful substances in the waste gas can contact and react with the spray liquid more fully. At the same time, the surface of the packing layer 46 usually has a certain roughness and pore structure. These structures provide a good place for the chemical reaction between the waste gas and the spray liquid. In this process, the chemical substances in the spray liquid react chemically with the harmful substances in the waste gas to convert them into harmless substances or substances that are easy to handle. At the same time, the spray liquid can also physically absorb certain harmful substances in the waste gas and transfer them from the gas phase to the liquid phase. The treated gas continues to flow upward, and the liquid containing pollutants is collected at the bottom of the tank 11 for subsequent treatment;

[0050] Then the gas will continue to pass through the rotating plate 52 and the biofilm 53 , the pollutants in the exhaust gas will be adsorbed and absorbed by the biofilm 53 , and finally the gas will be discharged from the top of the tank body 11 .

[0051] Embodiment 4: Based on Embodiments 1, 2 and 3, this embodiment is to achieve the effects of self-cleaning and intermittent oxygen injection for the entire biological purification component 5.

[0052] For details, see Figure 2 , Figure 7-11 The scraping assembly 6 includes a bevel gear transmission group 3 61, the inner surface of the bevel gear transmission group 3 61 is fixedly connected to the rotating rod 25, the bevel gear transmission group 3 61 is composed of two bevel gears, which are mainly used to change the rotation direction, and the lower end of the rotating plate 52 is rotatably connected to a collecting box 63, and the collecting box 63 remains stationary, so that the impurities remaining at the lower end of the rotating plate 52 can be scraped away, and the right side of the collecting box 63 is fixedly connected to the inner surface of the tank body 11, and the right side of the bevel gear transmission group 3 61 is fixedly connected to a rotating shaft 64, and the outer surface of the rotating shaft 64 is rotatably connected to the collecting box 63, and the right end of the rotating shaft 64 is fixedly connected to an eccentric block 65, and the outer surface of the eccentric block 65 is movable It is connected with a shaking plate 67, which is inclined. The eccentric block 65 will continuously knock on the shaking plate 67 when rotating, so as to shake away the impurities and residues scraped off the rotating plate 52 from the inside of the collecting box 63, so as to prevent too many impurities from accumulating inside the collecting box 63. The lower end of the shaking plate 67 is fixedly connected with a spring 66, so that the shaking plate 67 has elasticity and buffering. The right side of the collecting box 63 is fixedly connected with a drain port 68, which extends to the outer surface of the tank body 11, so as to discharge the impurities inside the shaking plate 67, and a valve is arranged inside the drain port 68. When the exhaust gas is purified, the valve is in a closed state to prevent the exhaust gas from leaking.

[0053] For further information, see Fig. 9 and Fig.10 The oxygen injection component 7 includes sliding grooves 71 symmetrically opened on the upper inner surface of the tank body 11. The left and right sides of the sliding grooves 71 are arc-shaped, which is convenient for the telescopic block 78 to slide back and forth. The upper part of the outer surface of the tank body 11 is symmetrically fixed with fixed bins 72. The interiors of the two fixed bins 72 are symmetrically provided with air bags 73. The outer surfaces of the two fixed bins 72 are symmetrically provided with one-way valves 74. The interior of the one-way valve 74 is connected to the air bag 73, and only air can be taken in but not out. After the air bag 73 is flattened, the one-way valve 74 will inflate the air bag 73 to make the air bag 73 bulge again. The lower sides of the two sliding grooves 71 are symmetrically provided with one-way valves 75. The interior of the one-way valve 75 is connected to the air bag 73, and only air can be taken out but not in. In the process of the air bag 73 being pressed, oxygen will be continuously sprayed to the biofilm 53, which can promote the activity of microorganisms and improve the biological purification efficiency.

[0054] For further information, see Figure 2 and Fig.11 The outer surface of the rotating rod 25 is symmetrically fixedly connected with a rotating block 76 on the upper side of the biofilm 53, and the inner surfaces of the two rotating blocks 76 are symmetrically fixedly connected with springs three 77, and one end of the two springs three 77 is symmetrically fixedly connected with telescopic blocks 78. The outer surfaces of the two telescopic blocks 78 are slidably connected to the rotating block 76. When the telescopic blocks 78 are obstructed, they will retract into the inside of the rotating block 76. The outer surfaces of the two telescopic blocks 78 are slidably connected to the sliding groove 71. When the telescopic blocks 78 pass through the sliding groove 71, they will automatically extend out and squeeze the airbag 73 during the rotation. The outer surfaces of the two telescopic blocks 78 are movably connected to the airbag 73, and the telescopic blocks 78 can intermittently squeeze the airbag 73. The outer surfaces of the two telescopic blocks 78 are rotatably connected to the inner surface of the tank body 11, and at this time, most of the telescopic blocks 78 are in a state of being retracted inside the rotating block 76.

[0055] The rotating plate 52 and the biofilm 53 can rotate together with the rotating rod 25. During the rotation, the bevel gear transmission group 3 61 drives the rotating shaft 64 and the eccentric block 65 to rotate. The eccentric block 65 continuously knocks the shaking plate 67 to vibrate the shaking plate 67, and the impurities and particles scraped off the surface of the shaking plate 67 are discharged from the sewage outlet 68. At the same time, during the rotation of the rotating rod 25, the rotating block 76 is driven to rotate together with the biofilm 53. There are two rotating blocks 76 on each layer, which are symmetrically arranged. When the telescopic block 78 contacts the inner surface of the tank body 11, the telescopic block 78 is at In the state of being retracted inside the rotating block 76, when the telescopic block 78 reaches the sliding groove 71, it loses the squeezing and will pop out, and then follows the rotating rod 25 to squeeze the airbag 73 while rotating, so that the oxygen in the airbag 73 is blown out from the one-way valve 2 75, and oxygen is injected into the biofilm 53. When the telescopic block 78 is separated from the sliding groove 71, the telescopic block 78 is pressed against the inner surface of the tank body 11 and rotates. At this time, the airbag 73 absorbs external oxygen from the one-way valve 1 74 and expands again, realizing intermittent oxygen injection into the biofilm 53. Because of its symmetrical arrangement, the entire biofilm 53 can be injected with oxygen.

[0056] Therefore, this solution uses the coordination among the rotating component 2, the spraying component 4, the biological purification component 5, the scraping component 6 and the oxygen injection component 7 to fully purify and filter the exhaust gas while cleaning the biological purification component 5, thereby preventing the rotating plate 52 from being contaminated and blocked after long-term use. In addition, oxygen injection is used to promote the activity of microorganisms, improve the biological purification efficiency, and extend the service life of the biofilm 53.

[0057] It should be noted that the specific installation method, circuit connection method and control method of the motor 22, spray pipe 1 43, spray pipe 2 44, biofilm 53 and airbag 73 used in the present invention are all conventional designs and will not be elaborated in detail in the present invention.
