Description

Technical Field

[0001] This utility model relates to the field of coating device technology, and in particular to a coating device for industrial waste gas purification catalyst. Background Technology

[0002] In the catalytic combustion process for waste gas treatment, reaction temperature plays a decisive role in the catalytic effect. If the temperature is too low, pollutants in the waste gas cannot react fully, significantly reducing purification efficiency; if the temperature is too high, it may damage the catalyst and pose safety hazards. Existing temperature control equipment mostly relies on various sensors to monitor the temperature in real time. Once a sensor malfunctions, the entire control system fails. Moreover, traditional equipment struggles to quickly respond to temperature fluctuations caused by changes in waste gas flow and composition, resulting in a relatively slow adjustment process that cannot meet the stable operation requirements under complex conditions. Therefore, there is an urgent need for a sensor-independent device that can quickly and effectively control the catalytic combustion temperature.

[0003] Patent document CN222325553U discloses a small-sample coating device for waste gas purification catalyst, relating to the field of catalysts. This utility model's small-sample coating device for waste gas purification catalyst includes a worktable, a conversion mechanism, a power propulsion mechanism, a slurry storage mechanism, and a small-sample coating mechanism. The conversion mechanism is rotatably connected to the worktable, and the power propulsion mechanism and the slurry storage mechanism are both mounted on the conversion mechanism. The power propulsion mechanism includes a drive motor, with a slurry piston at the end of the drive shaft of the drive motor. The slurry storage mechanism includes a storage tank with an inner cavity and openings at both ends. The slurry piston passes through the bottom opening of the storage tank and is located within the inner cavity of the storage tank; the other end opening of the storage tank is connected to the small-sample coating mechanism. With the above-mentioned configuration, this device can perform coating in both vertical and horizontal states, simulating the coating of catalyst carriers in assembly line production. At the same time, this device achieves the coating of catalyst carriers with less slurry, enabling the waste gas purification catalyst to be used for laboratory-level testing and research, reducing R&D costs. However, it does not solve the problems of easy transportation adaptation to coating plates of different shapes and quick replacement of spray nozzles. Therefore, we need an industrial waste gas purification catalyst coating device. Utility Model Content

[0004] This utility model discloses an industrial waste gas purification catalyst coating device, which aims to solve the technical problems of easy transportation adaptation to coating plates of different shapes and quick replacement of spray nozzles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An industrial waste gas purification catalyst coating device includes a conveying assembly. The conveying assembly includes a support frame. A vertical main support frame is fixedly installed on the lower surface of the inner wall of the support frame. Two sets of vertical secondary support frames are fixedly connected to both sides of the vertical main support frame. A vertical hydraulic cylinder group is installed inside the two sets of vertical secondary support frames. Two sets of support rods are fixedly connected to the top of the vertical hydraulic cylinder group. A conveyor belt device is movably connected to the top of the two sets of support rods and the top of the vertical main support frame.

[0007] A spraying assembly is fixedly connected to the top of the support frame. The spraying assembly includes a protective cover. A storage tank is fixedly connected to the top of the protective cover. A stirring assembly is rotatably connected inside the storage tank. A conveying pipe is fixedly connected to one side of the storage tank. A control valve is fixedly connected to the surface of the conveying pipe. The end of the conveying pipe away from the storage tank is connected to a storage container.

[0008] In a preferred embodiment, a spraying pump is installed inside the storage tank. The output end of the spraying pump is connected to a main feed pipe. A main compression head is fixedly connected to the end of the main feed pipe away from the spraying pump. Multiple spraying hoses are connected to the end of the main compression head away from the main feed pipe. Multiple spraying heads are fixedly connected to the ends of the multiple spraying hoses away from the main compression head, and multiple spray nozzles are threaded to the lower end of the spraying heads.

[0009] The coating is pumped out of the storage tank by a spray pump and sprayed out from multiple nozzles through the main delivery pipe, main compression head and spray hose, thus realizing the function of delivering the coating to the surface of the carrier to be coated and ensuring that the catalyst coating can cover all parts of the carrier.

[0010] In a preferred embodiment, two electric push rods are fixedly connected to the upper surface of the inner wall of the protective cover, and a strip mounting plate is fixedly connected to the bottom end of the two electric push rods. The upper surface of the strip mounting plate is provided with multiple holes, and multiple spray heads and multiple spray nozzles pass through the holes at the top of the strip mounting plate.

[0011] By controlling the extension and retraction of the electric push rod, the strip mounting plate is moved up and down, thereby adjusting the distance between the spray head and nozzle and the substrate to be coated. This allows for precise adjustment of the spraying distance according to the height of different substrates and coating requirements, ensuring that the coating is applied evenly and in appropriate amounts to the substrate.

[0012] In a preferred embodiment, the conveyor belt device includes three drive motors, which are respectively installed inside the vertical main support frame and two sets of vertical secondary support frames. The output ends of the three drive motors are rotatably connected to three sets of drive wheels.

[0013] By activating these three drive motors, the drive motors drive the three sets of drive wheels to rotate, thereby providing power to the conveyor belt device, which in turn drives the conveyor belt to transport the carrier to be coated.

[0014] In a preferred embodiment, three sets of driven wheels are rotatably connected to one side of each of the three sets of driving wheels. Two sets of supporting rotating columns are rotatably connected to the middle of each of the three sets of driving wheels and the three sets of driven wheels. A conveyor belt is movably connected to the top of each of the two sets of supporting rotating columns. Three sets of movable support plates are fixedly connected to both sides of each of the vertical main support frame and the two sets of vertical secondary support frames. Several auxiliary rotating columns are inserted through the middle of each of the three sets of movable support plates. Three sets of auxiliary driving wheels are rotatably arranged in the middle of each auxiliary rotating column. The driving wheels and driven wheels are all connected by belt drive.

[0015] The belt drive between the drive wheel, driven wheel and auxiliary drive wheel drives the support column to rotate, thereby making the conveyor belt run stably, realizing the smoothness and continuity of the carrier during the transportation process, and ensuring that the carrier can pass through the coating area smoothly.

[0016] In a preferred embodiment, the stirring assembly includes a waterproof shell, inside which a vertically mounted servo motor is fixedly installed. The output end of the vertically mounted servo motor is fixedly connected to a support shaft, and stirring rods are fixedly connected at equal intervals to the outer ring surface of the support shaft.

[0017] A vertically mounted servo motor drives the support shaft to rotate, which in turn drives the stirring rod to stir the catalyst coating in the storage tank. This achieves uniform mixing of the coating, prevents the components in the coating from settling and separating, and ensures the stability of the coating's performance to meet coating quality requirements.

[0018] In a preferred embodiment, a controller is fixedly mounted on the surface of the support frame, the controller including a control screen, and a group of control buttons is fixedly mounted on one side of the control screen.

[0019] Centralized control of all components of the coating device can be achieved by operating the control screen and control button group.

[0020] As can be seen from the above, the industrial waste gas purification catalyst coating device provided by this utility model has the following technical effects.

[0021] Firstly, the vertical hydraulic cylinder assembly plays a crucial role in the transportation process. It can drive the side conveyor belt device to rise or fall. When transporting flat coated panels, keeping the conveyor belt device parallel ensures smooth transport of the coated panels; while when dealing with coated panels with special shapes such as curved or wavy shapes, adjusting the rise or fall of the conveyor belt device can effectively adapt to their shape and meet different transportation needs.

[0022] During the spraying process, the mixing assembly first thoroughly mixes the material in the storage tank. Then, the control valve is opened, and the material is transported to the storage tank via the delivery pipe. Next, under the action of the spray pump, the material passes through the main delivery pipe, is compressed by the main compression head, and is then delivered to the spray head via the spray hose, finally being evenly sprayed from the nozzle. Throughout this process, an electric actuator moves related components up and down to assist in completing the coating work.

[0023] Furthermore, considering the varying requirements for spray nozzles in different coating scenarios, the spray head and nozzle are connected by a threaded connection. This allows operators to easily replace the spray nozzle according to actual needs.

[0024] In summary, by adjusting the conveyor belt device using a vertical hydraulic cylinder assembly, the system adapts to transport coating plates of different shapes; the coordinated operation of the mixing assembly, conveying system, and electric push rod ensures uniform spraying of the coating material; and the threaded connection design between the spray head and the nozzle facilitates easy nozzle replacement by operators, thus fully meeting the diverse needs of industrial waste gas purification catalyst coating processes in terms of transportation, spraying, and component replacement.

[0025] Secondly, the ingenious design of the control screen and control button assembly located on the surface of the support frame allows operators to easily control all components of the industrial waste gas purification catalyst coating device. This enables precise control of the coating device, making it easy to adjust the speed of the transport carrier and regulate the mixing and spraying of the coating, greatly improving the convenience and efficiency of the device's operation.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0034] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0035] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 The industrial waste gas purification catalyst coating device includes a conveying component 1, which includes a support frame 101. A vertical main support frame 102 is fixedly installed on the lower surface of the inner wall of the support frame 101. Two sets of vertical secondary support frames 103 are fixedly connected to both sides of the vertical main support frame 102. A vertical hydraulic cylinder group 104 is installed inside the two sets of vertical secondary support frames 103. Two sets of support rods 105 are fixedly connected to the top of the vertical hydraulic cylinder group 104. A conveyor belt device 2 is movably connected to the top of the two sets of support rods 105 and the top of the vertical main support frame 102.

[0036] A spraying assembly 3 is fixedly connected to the top of the support frame 101. The spraying assembly 3 includes a protective cover 301. A storage tank 302 is fixedly connected to the top of the protective cover 301. A stirring assembly 4 is rotatably connected inside the storage tank 302. A conveying pipe 303 is fixedly connected to one side of the storage tank 302. A control valve 315 is fixedly connected to the surface of the conveying pipe 303. The end of the conveying pipe 303 away from the storage tank 302 is connected to a storage container 304.

[0037] The storage tank 304 is equipped with a spraying pump 305. The output end of the spraying pump 305 is connected to a main conveying pipe 306. The end of the main conveying pipe 306 away from the spraying pump 305 is fixedly connected to a main compression head 307. The end of the main compression head 307 away from the main conveying pipe 306 is connected to multiple spraying hoses 308. The ends of the multiple spraying hoses 308 away from the main compression head 307 are fixedly connected to multiple spraying heads 309, and the lower end of the spraying head 309 is connected to multiple spray nozzles 311 by threads.

[0038] In this embodiment, the controller 5 on the surface of the support frame 101 becomes the core of operation when the industrial waste gas purification catalyst coating device is running. By operating the control button group 502 on the controller 5, the three drive motors 201 in the vertical main support frame 102 and the two sets of vertical secondary support frames 103 are started. The motors exert force, and their output ends cause the three sets of driving wheels 202 to rotate. With the transmission effect of the belt 209, the three sets of driven wheels 203 and the three sets of auxiliary driving wheels 208 rotate synchronously. This linkage effect drives the two sets of support rotating columns 204 in the middle of the three sets of driving wheels 202 and the three sets of driven wheels 203, thereby making the top conveyor belt 205 run, so as to achieve the conveying of the waste gas purification carrier on the conveyor belt.

[0039] It is worth noting that when transporting flat coatings, the operator only needs to adjust the parameters on the control screen 501 of the controller 5 to ensure that the three drive motors 201 operate at the same speed, thus ensuring that the three conveyor belt devices 2 are in a parallel state and achieving stable transport of the flat coating. If it is necessary to transport curved or wavy coatings, the controller 5 is also used to control the vertical hydraulic cylinder groups 104 within the two sets of vertical auxiliary support frames 103. By extending or shortening one side of the cylinder, the corresponding support rod 105 and the two conveyor belts will rise or fall, thereby meeting the transport standards for coatings of different shapes. Furthermore, considering the requirements for different operating heights, the operator can also use the controller 5 to extend or shorten the entire vertical hydraulic cylinder group 104, driving the entire conveyor belt device 2 to rise and fall via the two sets of support rods 105 connected at the top.

[0040] Reference Figure 3 and Figure 5Two electric push rods 312 are fixedly connected to the upper surface of the inner wall of the protective cover 301. The bottom ends of the two electric push rods 312 are fixedly connected to a strip mounting plate 313. The upper surface of the strip mounting plate 313 has multiple holes 314. Multiple spray heads 309 and multiple spray nozzles 311 pass through the holes 314 at the top of the strip mounting plate 313.

[0041] The conveyor belt device 2 includes three drive motors 201, which are respectively installed inside the vertical main support frame 102 and two sets of vertical secondary support frames 103. The output ends of the three drive motors 201 are rotatably connected to three sets of drive wheels 202.

[0042] Three sets of driving wheels 202 are rotatably connected to three sets of driven wheels 203 on one side. Two sets of support columns 204 are rotatably connected to the middle of the three sets of driving wheels 202 and the three sets of driven wheels 203. The top of the two sets of support columns 204 is movably connected to the conveyor belt 205. Three sets of movable support plates 206 are fixedly connected to both sides of the vertical main support frame 102 and the two sets of vertical secondary support frames 103. Several auxiliary columns 207 are inserted in the middle of the three sets of movable support plates 206. Three sets of auxiliary driving wheels 208 are rotatably set in the middle of the auxiliary columns 207. The driving wheels 202 and driven wheels 203 are all connected by belts 209.

[0043] The stirring assembly 4 includes a waterproof shell 401, inside which a vertically mounted servo motor 402 is fixedly installed. The output end of the vertically mounted servo motor 402 is fixedly connected to a support shaft 403, and stirring rods 404 are fixedly connected at equal intervals to the outer ring surface of the support shaft 403.

[0044] In this embodiment, after the carrier is in place, the operator activates the stirring assembly 4 of the storage tank 302 via the controller 5. At this time, the vertically mounted servo motor 402 inside the waterproof shell 401 drives the support shaft 403, which in turn drives the top stirring rod 404 to stir the catalyst coating, ensuring uniform mixing and preventing sedimentation and stratification. After stirring is complete, the coating flows into the storage tank 304 for storage through the conveying pipe 303 on one side of the storage tank 302.

[0045] Meanwhile, the strip mounting plate 313 connected below the electric push rod 312 on the upper surface of the inner wall of the protective cover 301 has multiple holes 314 on its surface through which the spray head 309 and the spray nozzle 311 pass.

[0046] It is worth noting that the spray head 309 and the spray nozzle 311 adopt a threaded connection design, which makes it easy for operators to replace them according to different coating needs, so as to adapt to different coating requirements.

[0047] Reference Figure 1A controller 5 is fixedly installed on the surface of the support frame 101. The controller 5 includes a control screen 501, and a control button group 502 is fixedly installed on one side of the control screen 501.

[0048] In this embodiment, when the operator needs to lift, transport, and coat the coating device, the controller 5 is designed to effectively and quickly control the coating device.

[0049] Working principle: First, the operator activates the three drive motors 201 within the vertical main support frame 102 and the two sets of vertical auxiliary support frames 103 via the control button group 502 on the surface controller 5 of the support frame 101. The motor outputs drive the three sets of drive wheels 202 to rotate, which, through the belt 209, causes the three sets of driven wheels 203 and the three sets of auxiliary wheels 208 to rotate synchronously. Then, the two sets of support rotating columns 204 in the middle of the three sets of drive wheels 202 and the three sets of driven wheels 203 drive the top conveyor belt 205 to operate, realizing the transport of the waste gas purification carrier on the conveyor belt.

[0050] When transporting flat coatings, the operator adjusts parameters on the control screen 501 of the controller 5 to control the three drive motors 201 to operate at the same speed, ensuring that the three conveyor belt devices 2 are parallel and achieving smooth transport of the flat coating. To transport curved or wavy coatings, the controller 5 operates the vertical hydraulic cylinder groups 104 within the two sets of vertical auxiliary support frames 103, extending or shortening one side of the cylinder to raise or lower the corresponding support rods 105 and the two conveyor belts on both sides, adapting to different coating transport standards. Furthermore, the operator can also use the controller 5 to extend or shorten the vertical hydraulic cylinder groups 104 as a whole according to different height requirements, driving the conveyor belt device 2 to rise or fall as a whole via the two sets of support rods 105 at the top.

[0051] After the carrier is delivered to its position, the operator starts the stirring assembly 4 inside the storage tank 302 on the controller 5. A vertically mounted servo motor 402 inside the waterproof casing 401 drives the support shaft 403 to rotate, causing the top stirring rod 404 to stir the catalyst coating, ensuring uniform mixing and preventing sedimentation and stratification. The stirred coating then flows into the storage tank 304 for storage via the conveying pipe 303 on one side of the storage tank 302.

[0052] Next, paint spraying is performed. The operator activates the spray pump 305 inside the storage tank 304 via controller 5, drawing out the paint, which is then sent to the main compression head 307 via the main delivery pipe 306. From there, it is distributed to multiple spray heads 309 via multiple spray hoses 308, and finally sprayed out from multiple nozzles 311 threaded to the lower end of the spray heads 309. Simultaneously, based on the height of the carrier, the operator adjusts the extension or retraction of the two electric push rods 312 on the upper surface of the inner wall of the protective cover 301 on controller 5, causing the strip mounting plate 313 to move up and down, adjusting the distance between the spray heads 309 and nozzles 311 and the carrier, ensuring that the paint is accurately and evenly applied to the carrier.

[0053] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
