Description

Technical Field

[0001] This invention belongs to the field of coating technology, specifically relating to a tail gas treatment mechanism for an integrated coating and recycling machine. Background Technology

[0002] Coating is a method of preparing composite materials (films) by applying a paste-like polymer, molten polymer, or polymer melt onto paper, cloth, or plastic film. Coating technology is widely used in coating and composite packaging of substrates such as paper and film.

[0003] The existing technology has the following problems: the coating process will cause environmental pollution to varying degrees, mainly air pollution. When treating the exhaust gas of the coating and recycling integrated machine, the existing devices have high treatment costs or high maintenance costs (because the existing devices mostly use intelligent control, which is convenient, but in actual investment, it will greatly increase our investment cost and subsequent maintenance cost for exhaust gas treatment). At the same time, the existing devices cannot meet the requirements of integrated continuous coating exhaust gas treatment (for example, the inlet and outlet of the gas need to be manually controlled, and the exhaust method and conditions also need to be manually controlled, resulting in poor continuity and portability). Therefore, there is an urgent need to solve this problem. Summary of the Invention

[0004] To address the problems mentioned in the background section, this invention provides a tail gas treatment mechanism for an integrated coating and recycling machine, which features convenient processing.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a tail gas treatment mechanism for a coating and recycling integrated machine, comprising a coating tail gas treatment chamber assembly, wherein a treatment chamber piston assembly is disposed inside the coating tail gas treatment chamber assembly, and an exhaust piston assembly is fixedly disposed on one side of the bottom of the coating tail gas treatment chamber assembly. The treatment chamber piston assembly forms a structure for suction and exhaust of air by moving the piston up and down within the coating tail gas treatment chamber assembly. When the piston moves up and down, the bottom end of the treatment chamber piston assembly forms a circumferential and self-rotating tail gas treatment plasma generation structure. Through the cooperation between the exhaust piston assembly and the coating tail gas treatment chamber assembly, a self-opening exhaust structure is formed inside the coating tail gas treatment chamber assembly when the piston moves down and a self-closing tail gas treatment structure is formed when the piston moves up.

[0006] In a preferred embodiment of the exhaust gas treatment mechanism of a coating and recycling integrated machine, the coating exhaust gas treatment chamber assembly includes a coating exhaust gas treatment cylinder. A drive motor is fixedly mounted on the top of the coating exhaust gas treatment cylinder via a top support rod. A crank arm is fixedly mounted on the output shaft of the drive motor. A spiral guide rail groove is provided on the inner wall of the coating exhaust gas treatment cylinder. An air inlet pipe and an exhaust pipe are respectively provided on both sides of the bottom of the coating exhaust gas treatment cylinder. A one-way valve is provided on both the air inlet pipe and the exhaust pipe. A venting ball slot seat is provided on the exhaust pipe. A first shaft is rotatably mounted on the top of the venting ball slot seat. A gear wheel and a venting ball head are fixedly mounted on the top and bottom of the first shaft, respectively. A venting ball head has a venting groove.

[0007] The processing chamber piston assembly includes a processing chamber piston, a push arm rotatably mounted on the top of the processing chamber piston, and an external gear ring platform rotatably mounted on the bottom of the processing chamber piston via a bearing. A guide rail protrusion is fixedly mounted on the outer side of the external gear ring platform. A central gear is fixedly mounted in the middle of the bottom surface of the processing chamber piston. The gear central shaft on the central gear is rotatably mounted on a support arm frame. Each arm of the support arm frame is coaxially rotatably mounted with an end gear and a plasma generator.

[0008] The exhaust piston assembly includes a piston cylinder, an exhaust piston is slidably disposed inside the piston cylinder, and a limit groove is formed on the inner wall of the piston cylinder. A limit protrusion is fixedly disposed on the side of the exhaust piston, and a push rod is fixedly disposed on one end of the exhaust piston. A rear toothed arm is fixedly disposed on one end of the push rod through a rear support rod, and a push spring is sleeved on the outside of the push rod.

[0009] In a preferred embodiment of the exhaust gas treatment mechanism of a coating and recycling integrated machine, the top of the curved arm and the top of the push arm are rotatably connected by a shaft and a bearing, and the bottom of the push arm is rotatably connected to the top of the treatment chamber piston. Through the cooperation of the curved arm structure between the curved arm and the push arm, the treatment chamber piston moves up and down inside the coating exhaust gas treatment cylinder.

[0010] In a preferred embodiment of the exhaust gas treatment mechanism of a coating and recycling integrated machine, the guide rail protrusion on the outer side of the external gear ring platform is inserted into the spiral guide rail groove on the inner wall of the coating exhaust gas treatment cylinder. When the piston in the treatment chamber moves up and down in the coating exhaust gas treatment cylinder, it slides in the guide rail groove through the guide rail protrusion. The external gear ring platform forms a rotating gear ring structure on the bottom surface of the piston in the treatment chamber.

[0011] In a preferred embodiment of the exhaust gas treatment mechanism of a coating and recycling integrated machine, the two sides of the plurality of end gears are respectively meshed with the outer side of the central gear and the inner side of the outer gear ring platform. As the outer gear ring platform rotates, the end gears form a structure that rotates around and on its own on the bottom surface of the piston in the treatment chamber.

[0012] In a preferred embodiment of the exhaust gas treatment mechanism of a coating and recycling integrated machine, one end of the piston cylinder is connected through to the outer wall of the coating exhaust gas treatment cylinder, the limiting protrusion slides within the limiting groove, and the two ends of the push spring abut against the exhaust piston and the inner wall of the rear end of the piston cylinder, respectively.

[0013] In a preferred embodiment of the exhaust gas treatment mechanism of a coating and recycling integrated machine, the rear toothed arm at the rear end of the push slide rod meshes with the toothed wheel. When the limiting protrusion slides to the rear end of the limiting groove, the rear toothed arm drives the air-purifying bulb head to rotate 90 degrees within the air-purifying bulb groove seat via the toothed wheel. When the limiting protrusion slides to the front end of the limiting groove, the rear toothed arm drives the air-purifying bulb head to rotate 90 degrees in the opposite direction within the air-purifying bulb groove seat via the toothed wheel.

[0014] In a preferred embodiment of the exhaust gas treatment mechanism of a coating and recycling integrated machine, in the initial state, the ventilation groove on the balloon head and the ventilation pipe of the exhaust pipe form a non-aligned, non-ventilated structure. When the balloon head rotates 90 degrees, the ventilation groove on the balloon head and the ventilation pipe of the exhaust pipe form an aligned ventilation structure.

[0015] Compared with the prior art, the beneficial effects of the present invention are as follows: The processing chamber piston assembly of the present invention forms an air extraction and exhaust structure with up and down piston movement within the coating exhaust gas treatment chamber assembly. When the processing chamber piston assembly moves up and down, its bottom end forms a circumferential and self-rotating exhaust gas treatment plasma generation structure. Simultaneously with the up and down piston movement, through the cooperation between the exhaust piston assembly and the coating exhaust gas treatment chamber assembly, a self-opening exhaust structure is formed inside the coating exhaust gas treatment chamber assembly when the piston moves down, and a self-closing exhaust gas treatment structure is formed when the piston moves up. Simply put, the rotation of the drive motor is converted into the up and down piston movement of the processing chamber piston assembly within the coating exhaust gas treatment chamber assembly. When it moves up, a coating exhaust gas extraction structure is formed within the coating exhaust gas treatment chamber assembly; when it moves down, an exhaust structure is formed within the coating exhaust gas treatment chamber assembly. Simultaneously, during the up and down piston movement, multiple plasma generators on the bottom surface of the processing chamber piston assembly form a circumferential and self-rotating structure as the piston moves up and down. In actual use, the plasma generator discharges and ionizes (… The plasma generator produces highly chemically active particles, such as electrons, ions, free radicals, and excited-state molecules. Pollutants in the coating exhaust gas react with these high-energy active groups, ultimately transforming into harmless substances, thus achieving the purpose of purifying the exhaust gas. Multiple plasma generators form a rotating and circumferential structure, creating a uniform purified exhaust gas environment inside the coating exhaust gas treatment chamber assembly, avoiding any purification blind spots. Based on the above coating exhaust gas treatment, when the piston assembly in the treatment chamber moves within the coating exhaust gas treatment chamber assembly... When the piston moves downward, the gas inside the coating exhaust gas treatment chamber assembly is pressurized. When the pressure reaches a certain level, the high-pressure gas generated by the piston moving downward pushes the exhaust piston backward. At this time, the exhaust piston overcomes the force of the push spring and slides backward. The rear toothed arm then drives the balloon head to rotate through the toothed wheel, forming an exhaust channel in the exhaust pipe. In this way, the exhaust is achieved when the piston moves downward, emptying the coating exhaust gas treatment chamber assembly and preparing for the next piston extraction and coating exhaust gas treatment.

[0027] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0028] Please see Figures 1-10As shown, the present invention provides an exhaust gas treatment mechanism for a coating and recycling integrated machine, including a coating exhaust gas treatment chamber assembly 100. A treatment chamber piston assembly 200 is disposed inside the coating exhaust gas treatment chamber assembly 100, and an exhaust piston assembly 300 is fixedly disposed on one side of the bottom of the coating exhaust gas treatment chamber assembly 100. The treatment chamber piston assembly 200 forms a structure for suction and exhaust of gas by moving the piston up and down within the coating exhaust gas treatment chamber assembly 100. When the piston moves up and down, the bottom end of the treatment chamber piston assembly 200 forms a ring-shaped and self-rotating exhaust gas treatment plasma generation structure. Through the cooperation between the exhaust piston assembly 300 and the coating exhaust gas treatment chamber assembly 100, a self-opening exhaust structure is formed inside the coating exhaust gas treatment chamber assembly 100 when the piston moves down and a self-closing exhaust gas treatment structure is formed when the piston moves up.

[0029] In a preferred embodiment, please refer to Figure 5 and Figure 6 The coating exhaust gas treatment chamber assembly 100 includes a coating exhaust gas treatment cylinder 101. A drive motor 104 is fixedly mounted on the top of the coating exhaust gas treatment cylinder 101 via a top support rod 105. A crank arm 103 is fixedly mounted on the output shaft of the drive motor 104. A spiral guide rail groove 102 is provided on the inner wall of the coating exhaust gas treatment cylinder 101. An air inlet pipe 113 and an exhaust pipe 111 are respectively provided on the bottom two sides of the coating exhaust gas treatment cylinder 101. A one-way valve 112 is provided on both the air inlet pipe 113 and the exhaust pipe 111. A venting ball seat 110 is provided on the exhaust pipe 111. A first shaft 107 is rotatably mounted on the top of the venting ball seat 110. A gear wheel 106 and a venting ball head 109 are fixedly mounted on the top and bottom of the first shaft 107, respectively. A venting groove 108 is provided on the venting ball head 109.

[0030] In a preferred embodiment, please refer to Figure 7 and Figure 8 The processing chamber piston assembly 200 includes a processing chamber piston 201. A push arm 202 is rotatably mounted on the top of the processing chamber piston 201, and an external gear ring platform 209 is rotatably mounted on the bottom of the processing chamber piston 201 via a bearing. A guide rail protrusion 203 is fixedly mounted on the outer side of the external gear ring platform 209. A central gear 204 is fixedly mounted in the middle of the bottom surface of the processing chamber piston 201. The gear central shaft 208 on the central gear 204 is rotatably mounted on the support arm frame 207. Each arm of the support arm frame 207 is coaxially rotatably mounted with an end gear 205 and a plasma generator 206.

[0031] In this embodiment, the two sides of the multiple end gears 205 are respectively meshed with the outer side of the central gear 204 and the inner side of the outer gear ring platform 209. As the outer gear ring platform 209 rotates, the end gears 205 form a structure that rotates around and on its own on the bottom surface of the processing chamber piston 201.

[0032] Secondly, please refer to it again. Figure 5 and Figure 6 The top of the crank arm 103 is rotatably connected to the top of the push arm 202 via a shaft and bearing, and the bottom of the push arm 202 is rotatably connected to the top of the treatment chamber piston 201. Through the cooperation of the crank arm structure between the crank arm 103 and the push arm 202, the treatment chamber piston 201 moves up and down inside the coating exhaust gas treatment cylinder 101.

[0033] Meanwhile, the guide rail protrusion 203 on the outer side of the external gear ring platform 209 is inserted into the spiral guide rail groove 102 on the inner wall of the coating exhaust gas treatment cylinder 101. When the treatment chamber piston 201 moves up and down in the coating exhaust gas treatment cylinder 101, the guide rail protrusion 203 slides in the spiral guide rail groove 102, and the external gear ring platform 209 forms a rotating gear ring structure on the bottom surface of the treatment chamber piston 201.

[0034] In a preferred embodiment, please refer to Figure 9 and Figure 10 The exhaust piston assembly 300 includes a piston cylinder 301, an exhaust piston 302 is slidably disposed inside the piston cylinder 301, and a limiting groove 304 is formed on the inner wall of the piston cylinder 301. A limiting protrusion 303 is fixedly disposed on the side of the exhaust piston 302, and a push rod 306 is fixedly disposed at one end of the exhaust piston 302. A rear toothed arm 307 is fixedly disposed at one end of the push rod 306 through a rear support rod 308, and a push spring 305 is sleeved on the outside of the push rod 306.

[0035] Secondly, please refer to it again. Figure 5 and Figure 6 One end of the piston cylinder 301 is connected to the outer wall of the coating exhaust gas treatment cylinder 101. The limiting protrusion 303 slides within the limiting groove 304. The two ends of the push spring 305 abut against the exhaust piston 302 and the inner wall of the rear end of the piston cylinder 301, respectively.

[0036] The rear toothed arm 307 at the rear end of the aforementioned pusher slide rod 306 meshes with the toothed wheel 106. When the limiting protrusion 303 slides to the rear end of the limiting slide groove 304, the rear toothed arm 307 drives the air-venting head 109 to rotate 90 degrees within the air-venting slot seat 110 via the toothed wheel 106. When the limiting protrusion 303 slides to the front end of the limiting slide groove 304, the rear toothed arm 307 drives the air-venting head 109 to rotate 90 degrees in the opposite direction within the air-venting slot seat 110 via the toothed wheel 106. In the initial state, the ventilation groove 108 on the air-venting head 109 and the ventilation pipe of the exhaust pipe 111 form a non-aligned, non-ventilated structure. When the air-venting head 109 rotates 90 degrees, the ventilation groove 108 on the air-venting head 109 and the ventilation pipe of the exhaust pipe 111 form an aligned ventilation structure.

[0037] In another embodiment of the present invention, the plurality of plasma generators 206 are in a circumferential and rotational structure. In order to ensure power supply, a circumferential coil can be provided on the piston 201 of the processing chamber, and an electrical connection contact can be provided on the plasma generator 206, with the electrical connection contact contact abutting against the circumferential coil.

[0038] In another embodiment of the present invention, in order to prevent gas in the coating exhaust gas treatment cylinder 101 from leaking from the spiral guide rail groove 102, an arc-shaped wear-resistant rubber sealing gasket can be provided on the outside of the outer gear ring platform 209 (near the guide rail protrusion 203). The arc-shaped wear-resistant rubber sealing gasket slides in the spiral guide rail groove 102 and seals it.

[0039] The multiple plasma generators 206 of this invention are known technologies, so they will not be described in detail.

[0040] The working principle of this invention is as follows: The processing chamber piston assembly 200 forms an air extraction and exhaust structure within the coating exhaust gas treatment chamber assembly 100, with the piston moving up and down. During the up and down piston movement, the bottom of the processing chamber piston assembly 200 forms a circumferential and rotating exhaust gas treatment plasma generation structure. Simultaneously with the up and down piston movement, through the cooperation between the exhaust piston assembly 300 and the coating exhaust gas treatment chamber assembly 100, a self-opening exhaust structure is formed inside the coating exhaust gas treatment chamber assembly 100 when the piston moves downwards, and a self-closing exhaust gas treatment structure is formed when the piston moves upwards. In simpler terms, the rotation of the drive motor 104 is converted into the up and down piston movement of the processing chamber piston assembly 200 within the coating exhaust gas treatment chamber assembly 100. When moving upwards, the coating... The exhaust gas treatment chamber assembly 100 forms an exhaust gas extraction structure. When it moves downward, the exhaust gas treatment chamber assembly 100 forms an exhaust structure after the exhaust gas has been treated. Simultaneously, when the piston moves up and down, multiple plasma generators 206 on the bottom surface of the piston assembly 200 form a rotating and self-rotating structure. In actual use, the discharge ionization of the plasma generators 206 (which generate highly chemically active particles such as electrons, ions, free radicals, and excited-state molecules) causes pollutants in the exhaust gas to react with these high-energy active groups, ultimately converting them into substances such as CO2, thereby achieving the purpose of purifying the exhaust gas. Multiple plasma generators 206 form a rotating and self-rotating structure, creating a uniform purified exhaust gas environment inside the coating exhaust gas treatment chamber assembly 100 and avoiding purification blind spots. Based on the above coating exhaust gas treatment, when the piston assembly 200 moves downwards within the coating exhaust gas treatment chamber assembly 100, the gas inside is pressurized. When the pressure reaches a certain level, the high-pressure gas generated by the piston's downward movement pushes the exhaust piston 302 backwards. The exhaust piston 302 overcomes the force of the push spring 305 and slides backwards. At this time, the rear gear arm 307 drives the inlet bulb head 109 to rotate via the gear wheel 106. An exhaust channel is formed inside the exhaust pipe 111. This allows for exhaust during piston downward movement, emptying the coating exhaust gas treatment chamber assembly 100 and preparing for the next piston extraction and coating exhaust gas treatment. The specific operating principle of this invention during piston upward movement is as follows: The device is installed on the coating exhaust gas pipeline, with the inlet pipe 113 connected to it. Both the inlet pipe 113 and the exhaust pipe 111 are equipped with one-way valves 112. When the piston assembly 200 in the treatment chamber moves upward within the coating exhaust gas treatment chamber assembly 100, the coating exhaust gas enters the coating exhaust gas treatment cylinder 101 through the inlet pipe 113. Since the guide rail protrusion 203 slides within the spiral guide rail groove 102, during piston upward movement...At this time, the external gear ring stage 209 rotates at the bottom of the processing chamber piston 201. Simultaneously, through the cooperation of the external gear ring stage 209, the end gears 205, and the central gear 204, multiple end gears 205 form a rotating and self-rotating structure around the bottom surface of the processing chamber piston 201. At this time, multiple plasma generators 206 form a rotating and self-rotating plasma treatment environment for the coating exhaust gas within the coating exhaust gas treatment cylinder 101, avoiding blind spots within the coating exhaust gas treatment cylinder 101 during treatment, and to a certain extent... To ensure the uniformity of coating exhaust gas treatment, it is important to emphasize that when the piston moves upward, the venting groove 108 on the venting bulb head 109 and the venting pipe of the exhaust pipe 111 form a misaligned, non-ventilated structure. When the piston moves downward, based on the above treatment, the drive motor 104 drives the piston 201 in the treatment chamber to move downward within the coating exhaust gas treatment cylinder 101 via the crank arm 103 and the push arm 202. During this downward movement, the guide rail protrusion 203 slides within the spiral guide rail groove 102, resulting in... The plasma generator 206 also creates a rotating and self-rotating plasma treatment environment for coating exhaust gas within the coating exhaust gas treatment chamber 101. Simultaneously, as the piston moves downwards, the gas pressure inside the coating exhaust gas treatment chamber 101 increases. When the pressure reaches the rated value, the high-pressure gas in the coating exhaust gas treatment chamber assembly 100 pushes the exhaust piston 302 backwards. At this point, the exhaust piston 302 overcomes the force of the push spring 305 and slides backwards. Simultaneously, the rear gear arm 307, through the gear wheel 10... 6 drives the air-venting bulb head 109 to rotate. When the air-venting bulb head 109 rotates 90 degrees, the air venting groove 108 on the air-venting bulb head 109 and the air venting pipe of the exhaust pipe 111 form a directly opposite air venting structure. At this time, an exhaust channel is formed in the exhaust pipe 111. In this way, exhaust is achieved when the piston moves downward, emptying the coating exhaust gas treatment chamber assembly 100 and preparing for the next piston evacuation and coating exhaust gas treatment. This method, without affecting the piston's air intake and exhaust, also serves a safe pressure relief function.

[0041] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
