Abstract
Description
Technical Field
[0001] This utility model relates to the field of spraying technology in centrifuge manufacturing, specifically a spraying device for centrifuge manufacturing. Background Technology
[0002] A centrifuge is a mechanical device that uses centrifugal force to separate different components in a mixture. Centrifugal force is generated by a high-speed rotating drum, causing solid particles or liquid droplets in the mixture to separate according to their density, size, and shape. Heavier substances (usually solids) move to the outside of the drum, while lighter substances (usually liquids) remain inside. It is widely used in chemical, food processing, pharmaceutical, environmental protection, mining, and laboratory fields. A centrifuge consists of multiple electrical components that work together, and the outer casing protects the internal electrical components and absorbs vibrations.
[0003] The manufacturing process of existing centrifuge shells requires surface coating to form a protective layer or impart specific functions (such as corrosion resistance, wear resistance, insulation, etc.). Existing centrifuge shells come in two types: bent and curved. During the coating process, the nozzles spray directly onto the shell surface, making it difficult to coat the bent or curved surfaces evenly. After the shell is removed from the coating machine, manual touch-ups are required, resulting in low coating efficiency. Furthermore, the exhaust gas from the coating machine is not deodorized or purified, causing air pollution. Utility Model Content

[0023] The present application will now be described in detail with reference to the accompanying drawings and specific embodiments.
[0024] Example
[0025] like Figures 1-5As shown, a spraying device for centrifuge manufacturing includes: a spraying machine 1, a workpiece rack 101 located at the top of the inside of the spraying machine 1, a plurality of lifting rings 102 installed at the bottom of the workpiece rack 101, hooks 103 movably fastened to the bottom of the lifting rings 102, a door 1011 located on the outside of the spraying machine 1 and connected by a hinge, spraying components located on both sides inside the spraying machine 1, the spraying components including: a spraying pipe 2, a diversion pipe 201, a straight nozzle 202, an angled nozzle 203, a pressure tank 204, a paint pipe 205 and a material pump 206, and an odor removal component located outside the spraying machine 1, the odor removal component including: an odor removal box 4, an air intake pipe 401, a filter screen 402, an activated carbon filter 403 and a suction fan 404.
[0026] The spraying machine 1 has an equipment box 104 fixedly installed at the top inside. A forward and reverse motor 105 is installed on one side inside the equipment box 104. The output end of the forward and reverse motor 105 drives a threaded screw 106. The other end of the threaded screw 106 is rotatably connected to the inner wall of the equipment box 104 through a bearing. A threaded sleeve 107 is threadedly connected to the threaded screw 106. A hanging rod 108 is installed between the threaded sleeve 107 and the workpiece holder 101. The bottom of the equipment box 104 has a moving groove for the hanging rod 108 to move. When spraying the shell of the centrifuge, the screw hole of the shell is hung on the hook 103, so that the shell is suspended inside the spraying machine 1, which makes it easy to place the shell stably and facilitates the spraying process.
[0027] The spraying machine 1 is equipped with a ring-shaped spraying pipe 2 on its exterior. Inside the spraying machine 1, on both sides, there are diversion pipes 201 connected to the spraying pipe 2. A straight nozzle 202 is installed inside the diversion pipe 201. An angled nozzle 203 is installed at the top and bottom of the straight nozzle 202. A pressure tank 204 is installed at the outer end of the spraying machine 1. A paint pipe 205 is installed between the paint outlet end at the bottom of the pressure tank 204 and the paint inlet end of the spraying pipe 2. A material pump 206 is installed on the paint pipe 205.
[0028] After suspending the outer casing inside the spray painting machine 1 and closing the door 1011, start the forward and reverse motor 105. The forward and reverse motor 105 drives the threaded screw 106 to rotate forward, and the threaded sleeve 107 rotates on the threaded screw 106 and moves to the right. That is, the threaded sleeve 107 drives the suspension rod 108, workpiece holder 101, hook 103, and outer casing to move to the right. Observe the movement position through the observation window of the door 1011. When the outer casing moves between the straight spray head 202 and the angled spray head 203 on both sides inside the spray painting machine 1, turn off the forward and reverse motor 105 to stop working, and start... When the material pump 206 operates, it generates a negative pressure suction at the paint outlet to draw the paint out of the pressure tank 204 and discharge it into the spray pipe 2. The paint is then diverted from the diversion pipe 201 to the straight nozzle 202 and the angled nozzle 203 to spray onto the surface of the outer shell. The straight nozzle 202 and the angled nozzle 203 are spaced apart. The straight nozzle 202 sprays the paint onto the outer shell surface in a straight line, while the angled nozzle 203 can spray the paint onto the curved or arc-shaped surfaces of the outer shell at an angle, ensuring uniform coating on the outer shell surface, reducing the amount of repainting work for workers, and improving the coating efficiency of the centrifuge outer shell.
[0029] During the spraying process on the outer shell surface, the outer shell can be driven to move left and right between the straight spray head 202 and the angled spray head 203 on both sides inside the spraying machine 1, so that different positions on the outer shell surface can be sprayed evenly.
[0030] A feeding pipe is installed on the top of the pressure tank 204, through which paint can be added to the pressure tank 204 for later use.
[0031] An air compressor 207 is installed at the outer end of the pressure tank 204. An air pipe 208 is installed between the air outlet of the air compressor 207 and the air inlet of the pressure tank 204. The air outlet of the pressure tank 204 is connected to the spray pipe 2. When the pressure tank 204 is in use, the air compressor 207 provides a stable air source to the pressure tank 204 and the spray pipe 2, increasing the air pressure of the spray pipe 2 to spray out the paint. This allows the paint to form a spray under air pressure and be sprayed onto the surface of the outer shell, which can make the paint adhere better to the surface of the outer shell and avoid paint waste.
[0032] The spraying machine 1 has lamp holders 3 fixed to both sides of its inner wall by bolts. Multiple drying lamps 301 are installed inside the lamp holders 3. After the outer shell is finished being sprayed, the machine drives the outer shell to move to the right between the lamp holders 3, so that it is directly opposite the multiple drying lamps 301. Then, the forward and reverse motor 105 is turned off and the work is stopped. The drying lamps 301 are turned on to generate heat to dry the outer shell, so that the paint on the outer shell dries quickly. After drying, the forward and reverse motor 105 is turned on again. The forward and reverse motor 105 drives the threaded screw 106 to reverse. The threaded sleeve 107 rotates on the threaded screw 106 and moves to the left. That is, the threaded sleeve 107 drives the hanging rod 108, the workpiece holder 101, the hook 103 and the outer shell to move to the left to the door 1011. At this time, the forward and reverse motor 105 is turned off and the work is stopped. The door 1011 is opened, and the outer shell is removed from the hook 103 after putting on heat-resistant gloves.
[0033] The sprayer 1 is equipped with an odor removal box 4 at its outer end. An air suction pipe 401 is installed between the odor removal box 4 and the sprayer 1. A filter screen 402 is installed on one side of the odor removal box 4, and an activated carbon filter 403 is installed on one side of the filter screen 402. A suction fan 404 is installed on one side of the activated carbon filter 403. During the spraying process, the paint contains VOCs mixed in the gas. When the suction fan 404 is started, it generates negative pressure to draw out the gas generated by the spraying inside the sprayer 1. Harmful VOCs will be discharged into the outside air along with the gas. During the exhaust process, the gas passes through the filter screen 402, which can filter out paint particles and impurities. When it passes through the activated carbon filter 403, the adsorption capacity of the activated carbon is used to further remove impurities, pollutants and harmful substances in the gas. Thus, the exhaust spraying gas is deodorized and purified, avoiding direct discharge that pollutes the air environment.
[0034] The deodorizing box 4 has a recessed slot 405 inside for engaging and fixing the filter screen 402 and activated carbon filter 403. A discharge port 406 is located on one side of the bottom of the filter screen 402, and a collection box 407 is located at the bottom of the discharge port 406. When using the filter screen 402 and activated carbon filter 403, the sealed door on the outside of the deodorizing box 4 is opened, and the filter screen 402 and activated carbon filter 403 are inserted into the corresponding recessed slots 405 for engagement and fixing. The sealed door is then closed tightly to hold the filter screen 402 and activated carbon filter in place. The outer side of 403 ensures that the filter screen 402 and activated carbon filter 403 are placed securely for use. The paint particles and impurities filtered by the filter screen 402 fall into the collection box 407 from the discharge port 406 and are collected, preventing blockage inside the deodorizing box 4 from affecting exhaust. When it is necessary to clean the impurities in the collection box 407 or replace the filter screen 402 and activated carbon filter 403, the sealed door can be opened directly to easily remove the collection box 407 or pull out the filter screen 402 and activated carbon filter 403 from the concave slot 405.
[0035] Working principle:
[0036] When spraying the centrifuge casing, hang the casing's screw holes on hooks 103, suspending the casing inside the spraying machine 1 for stable placement. After suspending the casing inside the spraying machine 1 and closing the door 1011, start the forward and reverse motor 105. The motor 105 drives the threaded screw 106 to rotate forward, causing the threaded sleeve 107 to rotate on the threaded screw 106 and move to the right. This means the threaded sleeve 107 drives the suspension rod 108, workpiece holder 101, hooks 103, and casing to move to the right. Observe the movement through the observation window of the door 1011. When the casing moves to the sides of the spraying machine 1, the direct spray nozzles 202 and the oblique spray nozzles... When the nozzles 203 are in operation, the forward and reverse motors 105 are turned off and the material pump 206 is started. The material pump 206 generates a negative pressure suction at the paint outlet to draw out the paint from the pressure tank 204 and discharge it into the spray pipe 2. The paint is then diverted from the diversion pipe 201 to the straight nozzle 202 and the angled nozzle 203 to spray onto the surface of the outer shell. The straight nozzle 202 and the angled nozzle 203 are spaced apart. The straight nozzle 202 sprays the outer shell surface in a straight line, while the angled nozzle 203 can spray the curved or arc-shaped surfaces of the outer shell at an angle, ensuring uniform coating on the outer shell surface, reducing the amount of re-spraying work for workers, and improving the coating efficiency of the centrifuge outer shell.
[0037] During the coating process, VOCs in the paint are mixed in the gas. When the suction fan 404 is started, it creates negative pressure to draw air from the deodorizing box 4 and the suction pipe 401, thus extracting the gas generated during the coating process inside the sprayer 1. Harmful VOCs are discharged into the outside air along with the gas. During the exhaust process, the gas passes through the filter screen 402, which can filter out paint particles and impurities. Then, when it passes through the activated carbon filter 403, the adsorption capacity of the activated carbon is used to further remove impurities, pollutants, and harmful substances from the gas. This process deodorizes and purifies the exhaust sprayed gas, preventing it from being directly discharged and polluting the air environment.
