Description

Technical Field

[0001] This utility model belongs to the field of anti-corrosion coating production and processing technology, and specifically relates to an anti-sedimentation storage device for anti-corrosion coating production and processing. Background Technology

[0002] Anti-corrosion coatings, as an indispensable type of paint, can protect metals from corrosion under normal conditions, extending the service life of non-ferrous metals. Proper storage of raw materials, semi-finished products, and finished products is a crucial step in the production process of anti-corrosion coatings, and current technologies typically use storage tanks to accomplish this. Chinese Patent No. CN217919278U discloses a storage device for the production of anti-corrosion coatings. The device includes a lower housing with an opening at the top. An upper housing is slidably and sealingly fitted onto the lower housing. The upper housing has an opening at the bottom and a feed inlet at the top. The lower housing has a discharge outlet at the bottom. An exhaust valve is also located at the top of the upper housing. The exhaust valve consists of a valve pipe and a valve core. The valve pipe is fixedly installed at the top of the upper housing and communicates with the lower housing. The valve core is slidably and sealingly installed inside the valve pipe. This device offers advantages such as ease of use and the ability to vacuum-store raw materials to prevent moisture absorption or deterioration. However, the aforementioned device still has obvious defects and shortcomings in practical applications. Firstly, the overall structure of the device is relatively simple. During use, the tank lacks a stirring and mixing structure, causing the coating inside the tank to remain in a static state. Due to the inherent characteristics of the anti-corrosion coating, sedimentation is very likely to occur during long-term storage. Solid particles in the coating will gradually settle to the bottom, resulting in uneven distribution of coating components. This sedimentation not only affects the quality of the anti-corrosion coating, causing its performance to decline and failing to achieve the expected anti-corrosion effect, but also makes it difficult to remove and reprocess the coating in subsequent use, requiring additional stirring treatment, increasing production steps and costs. Secondly, for anti-corrosion coatings that need to be stored for a long time, this storage method without stirring function makes it difficult to ensure the uniformity and stability of the coating during storage. In severe cases, it may lead to the scrapping of the coating, causing unnecessary losses to production. It is evident that the existing technology has certain limitations in the storage of anti-corrosion coatings and urgently needs to be improved in design. Utility Model Content

[0007] As a preferred technical solution, the adjustment mechanism includes a guide rail, which is fixedly installed on the top of the fixed frame. A first motor is fixedly installed on the bottom of the guide rail and is fixedly installed on the inner side of the fixed frame.

A slider is threadedly connected to the outer surface of the lead screw. A connecting arm is fixedly installed on the front of the slider, and a top plate is fixedly installed on the front of the moving end of the connecting arm.

[0008] As a preferred technical solution, the driving mechanism includes a side plate and a worm gear. The side plate is fixedly installed at both ends of the top of the top plate. A worm is rotatably connected to the inner side of the side plate. The worm gears are rotatably connected to the top of the top plate in a linear arrangement with equal spacing. The worm gears and the worm are connected by a transmission. The bottom of the worm gear is connected to the top of the rotating shaft.

Combined with the conical stirring auger and the bottom of the storage tank, it allows for flexible stirring of multiple batches of paint during use, and reduces residue during material removal, thus improving operational flexibility and paint utilization. At the same time, the plug-in design of its top drive mechanism can assist in positioning each storage tank, ensuring the overall stability of the storage tanks. Existing technologies suffer from problems such as limited device functionality, inconvenience of use, and easy paint residue. Attached Figure Description

[0014] Example

[0015] refer to Figures 1 to 6 This embodiment of an anti-settling storage device for the production and processing of anti-corrosion coatings includes a base plate 1, a fixed frame 2 fixedly installed in the middle of the rear side of the top of the base plate 1, an adjustment mechanism 3 fixedly installed on the top of the fixed frame 2, a drive mechanism 4 fixedly installed on the front of the adjustment mechanism 3, and storage tanks 5 fixedly installed on the top of the base plate 1 in a linear arrangement at equal intervals. A stirring mechanism 6 is rotatably connected inside the storage tank 5, and the top of the stirring mechanism 6 passes through the storage tank 5 and is connected to the bottom output end of the drive mechanism 4. The drive mechanism 4 includes a top plate 41, which is fixedly installed on the front of the moving end of the drive mechanism 4. A drive module 42 is fixedly installed on the top of the top plate 41. Rotating shafts 43 are rotatably connected to the bottom of the top plate 41 in a linear arrangement at equal intervals. A plug 44 is fixedly installed on the bottom of the rotating shaft 43 and is inserted into the top of the stirring mechanism 6. The output end of the drive mechanism 4 is connected to the top of the rotating shaft 43. During the operation of this device, the drive mechanism 4 is moved by the adjusting mechanism 3, so that the plug 44 of the drive mechanism 4 mates with the stirring mechanism 6. When 42 is running, power is transmitted to the rotating shaft 43, which drives the plug 44 to rotate, thereby driving the stirring mechanism 6 to operate in the storage tank 5. The stirring mechanism 6 stirs the anti-corrosion coating in the tank, which can prevent the coating from settling and ensure the uniformity of the coating composition. When different storage tanks 5 need to be treated, the adjusting mechanism 3 drives the driving mechanism 4 to move, so as to connect with the stirring mechanism 6 of other storage tanks 5. There is no need to configure a driving component for each storage tank 5 separately, which reduces equipment costs, improves the ease of operation, and can efficiently meet the anti-settling requirements of multiple storage tanks 5.

[0016] refer to Figures 2-3The stirring mechanism 6 includes a top cover 61, which is bolted to the top of the storage tank 5. A socket 62 is rotatably connected to the center of the top of the top cover 61, and a plug 44 is inserted into the inside of the socket 62. An agitator 63 is rotatably connected to the bottom of the top cover 61. The top of the agitator 63 is fixedly connected to the bottom of the socket 62. Agitator plates 64 are fixedly connected at equal intervals to the outer surface of the agitator 63. An agitator 65 is fixedly installed at the lower end of the outer surface of the agitator 63. The agitator 65 is conical in shape, and the bottom of the storage tank 5 is also conical. A feed pipe 66 is fixedly connected to one side of the top of the top cover 61, and a sealing cap 67 is threaded to the top of the feed pipe 66. During the operation of this device, anti-corrosion agents are injected into the storage tank 5 through the feed pipe 66. After the paint is injected, the sealing cap 67 is tightened to ensure airtightness. The top cover 61 is fixed to the top of the storage tank 5 with bolts. When the plug 44 of the drive mechanism 4 is inserted into the socket 62, the power is transmitted to the stirring shaft 63, which rotates. When the stirring shaft 63 rotates, the stirring plate 64 on its outer surface rotates accordingly, stirring the paint in the tank and preventing the paint components from separating. The stirring auger 65 at the bottom rotates synchronously. Because it and the bottom of the storage tank 5 are both conical, it can push the paint at the bottom of the tank, preventing the paint from settling and accumulating at the bottom. This structure keeps the paint in a uniform state during storage, reducing quality problems caused by sedimentation. At the same time, the stable installation of the top cover 61 also provides a stable environment for the stirring process, ensuring that the stirring operation is reliable.

[0017] refer to Figures 1-6The adjusting mechanism 3 includes a guide rail 31, which is fixedly installed on the top of the fixed frame 2. A first motor 32 is fixedly installed on the bottom of the guide rail 31 and is fixedly installed inside the fixed frame 2. A lead screw 33 is fixedly installed at the output end of the first motor 32 and is rotatably connected to the inside of the guide rail 31. A slider 34 is threadedly connected to the outer surface of the lead screw 33. A connecting arm 35 is fixedly installed on the front of the slider 34, and a top plate 41 is fixedly installed on the moving part of the connecting arm 35. On the front, the drive mechanism 4 includes a side plate 421 and a worm gear 422. The side plate 421 is fixedly installed at both ends of the top of the top plate 41. A worm gear 423 is rotatably connected to the inner side of the side plate 421. The worm gears 422 are linearly arranged at equal intervals and rotatably connected to the top of the top plate 41. The worm gears 422 and the worm gear 423 are connected by a transmission. The bottom of the worm gears 422 is connected to the top of the rotating shaft 43. A second motor 424 is fixedly installed on the outer side of one side plate 421. The output end of the second motor 424 passes through... One end of the top rail and worm gear 423 is fixedly connected. During the application of this device, the first motor 32 of its adjusting mechanism 3 drives the lead screw 33 to rotate inside the guide rail 31. The lead screw 33 drives the slider 34 to move along the guide rail 31. The slider 34 drives the top plate 41 and the driving mechanism 4 to move synchronously through the connecting arm 35, so that the driving mechanism 4 can be docked with the stirring mechanism 6 of different storage tanks 5. The second motor 424 of the driving mechanism 4 drives the worm gear 423 to rotate. The worm gear 423 and the worm wheel 422 drive multiple worm wheels 422 to rotate synchronously. The worm wheel 422 drives the rotating shaft 43 to rotate, transmitting power to the stirring mechanism 6. This design allows the driving mechanism 4 to flexibly switch docking objects without having to configure a separate driving component for each storage tank 5, reducing equipment costs. At the same time, the synchronous operation of multiple worm wheels 422 ensures the stable transmission of stirring power, improves the efficiency and consistency of multi-tank stirring operation, and ensures that the coating in each storage tank 5 can be uniformly stirred, effectively preventing sedimentation.

[0018] refer to Figures 1-4The storage tank 5 has support legs 7 fixedly installed in a ring at equal intervals at its bottom. A discharge valve 10 is fixedly installed at the bottom output end of the storage tank 5. The discharge valve 10 allows for the discharge of stored paint, facilitating rapid material removal by the equipment. A base plate 8 is fixedly installed at the bottom of the support legs 7. A circular frame 9 is fixedly installed in a linear arrangement at equal intervals on the top of the base plate 1. The base plate 8 is placed on top of the circular frame 9 and is located inside the circular frame 9. During operation, the storage tank 5 is placed inside the circular frame 9 on top of the base plate 1 via the support legs 7 and the base plate 8. The circular frame 9... The storage tank 5 forms a limit to prevent it from shifting or shaking during the stirring process, ensuring the stability of the stirring operation. The support leg 7 raises the storage tank 5 to a certain height, leaving space between the bottom of the storage tank 5 and the base plate 1. This facilitates subsequent possible material discharge operations and reduces the direct impact of the ground environment on the storage tank 5. The base plate 8 increases the contact area with the circular frame 9, further improving the stability of the storage tank 5 and making the entire storage structure more reliable during equipment operation. This provides a basic guarantee for the stable operation of the stirring mechanism 6 inside the tank and indirectly ensures the continuous performance of the anti-sedimentation effect.

[0019] Operating principle and advantages: During the application of this device, the base plate 1 is placed in the designated position, providing a stable installation foundation for the entire device. The storage tank 5 is stably placed in the placement frame 9 on top of the base plate 1 by the support legs 7 and the base plate 8. The placement frame 9 can accurately position the storage tank 5, effectively preventing the storage tank 5 from shaking during subsequent stirring. Open the sealing cap 67 of the top feed pipe 66 of the top cover 61, and slowly inject the raw materials, semi-finished products or finished products of the anti-corrosion coating into the storage tank 5 through the feed pipe 66. After injection, tighten the sealing cap 67 in time to ensure that the storage tank 5 has good sealing performance and avoids excessive contact between the coating and the outside air, which would affect the quality. At this time, the adjustment mechanism 3... Both the drive mechanism 4 and the stirring mechanism 6 are in their initial state, with the plug 44 and socket 62 separated. The first motor 32 of the adjustment mechanism 3 is started, and the motor drives the lead screw 33 to rotate. The lead screw 33 drives the slider 34 to slide smoothly along the guide rail 31. The slider 34 drives the top plate 41 and the drive module 42 mounted on the top plate 41 to move synchronously through the connecting arm 35, so that the plug 44 at the bottom of the drive mechanism 4 is accurately aligned with the socket 62 at the top of the storage tank 5. The top plate 41 is moved further to firmly insert the plug 44 into the socket 62, completing the power connection between the drive mechanism 4 and the stirring mechanism 6. The precise movement characteristics of the adjustment mechanism 3 ensure that the drive mechanism 4 and the stirring mechanism 6 can be efficiently connected. After the drive mechanism 4 and the stirring mechanism 6 are connected, the second motor 424 of the drive mechanism 4 is started. The motor drives the worm gear 423 to rotate. The worm gear 423 and the worm wheel 422 cooperate to drive the transmission, so that multiple worm wheels 422 rotate synchronously. The worm wheels 422 then drive the rotating shaft 43 and the plug 44 to rotate. The plug 44 transmits power to the stirring shaft 63 through the socket 62, driving the stirring shaft 63 to rotate inside the storage tank 5. When the stirring shaft 63 rotates, it drives the stirring plate 64 and the stirring auger 65 on its outer surface to rotate together. The stirring plate 64 stirs the coating in the storage tank 5. The horizontal stirring ensures thorough mixing of different layers of coating, while the stirring auger 65 pushes the coating at the bottom of the storage tank 5 vertically to prevent sedimentation. The combined effect of these two mechanisms effectively prevents sedimentation during storage, addressing the sedimentation problem caused by the lack of a stirring structure in existing technologies. This ensures the uniformity of the coating composition and significantly improves the quality stability of the coating during storage. During use, the device can be started periodically according to the storage requirements of the coating to achieve regular stirring and further avoid sedimentation caused by long-term stagnation. When it is necessary to stir the paint in other storage tanks 5, first turn off the second motor 424 to stop the current stirring operation, then start the first motor 32 to rotate in the opposite direction, drive the slider 34 to drive the drive mechanism 4 to reset as a whole, so that the plug 44 can be smoothly separated from the socket 62 of the current storage tank 5. After that, the drive mechanism 4 moves to the position of the next storage tank 5 that needs to be stirred, and repeats the above docking steps to stir the paint in the storage tank 5. This design greatly improves the flexibility of operation and can meet the needs of storing and stirring multiple batches of paint at the same time. When it is necessary to take out the paint in the storage tank 5, first stop the stirring operation, open the discharge structure at the bottom of the storage tank 5, and the paint is smoothly discharged under the action of gravity. Since the stirring auger 65 and the bottom of the storage tank 5 are both conical, the paint residue in the tank can be effectively reduced, and the utilization rate of the paint can be improved. During the entire use process, the various mechanisms work together to reduce the additional processing steps before the paint is used, reduce production costs, and ensure that the performance of the paint is not affected by storage. Storage tank 5 has a volume of 50-500L. The length of stirring plate 64 is 1 / 3-2 / 3 of the inner diameter of storage tank 5, and its thickness is 3-8mm. The spacing between adjacent stirring plates 64 is 10-30cm. The stirring auger 65 has a pitch of 15-40cm, a taper of 5°-15°, and a length of 1 / 4-1 / 2 of the height of storage tank 5. The feed pipe 66 has a diameter of 5-15cm, and the sealing cap 67 is threaded with the feed pipe 66 in M20-M50 configurations. Among the electronic components, the first motor 32 and the second motor 424 are both three-phase asynchronous motors, model Y2-80M1-2, with a power of 0.75kW and a rated speed of 2800r / min. The controller is a PLC. The controller, model S7-200SMART, is installed on the outer middle of the fixed frame 2. The power supply method is as follows: the controller is connected to the first motor 32 and the second motor 424 through copper core cables with a cross-sectional area of ​​1.5-2.5mm², and connected to AC380V three-phase power supply. After receiving the command, the controller controls the motor to start, stop and rotate. The scope of protection of this application does not involve improvements to the electronic components of the device or equipment. Therefore, the working principles of each electronic component are not described in detail here. The electronic components in this application are all conventional electronic components used in the prior art. They are all conventional technical means in the prior art, and the application of the prior art is very mature. Therefore, they will not be elaborated here.
