Description

Technical Field

[0001] The utility model relates to the technical field of anti-corrosion coating production, and more specifically, to a low-temperature stirring device for anti-corrosion coating production. Background Art

[0002] Anticorrosive coating is a coating used to prevent corrosion of metal or other materials. It forms a protective film to isolate the object from the external environment and prevent erosion by corrosive media. When producing anticorrosive coating, it is necessary to place raw materials such as resin, pigment, filler, additive and solvent in a stirring device in proportion according to the purpose and performance requirements of the coating. During the stirring process, in order to ensure the stability of the coating composition, low-temperature stirring is usually used. The existing low-temperature stirring device for the production of anticorrosive coatings usually does not have a crushing component. Since solid raw materials are prone to agglomeration during storage, if the agglomerated solid raw materials are directly placed in the stirring tank for stirring, the agglomerated raw materials are not easy to disperse, thereby reducing the uniformity of stirring and affecting the quality of the produced anticorrosive coating; secondly, the existing low-temperature stirring device for the production of anticorrosive coatings will produce unpleasant odors when stirring solid raw materials and solvents. These odors will diffuse into the surrounding environment with the feed hopper. If inhaled into the mouth and nose by the staff, it will cause serious discomfort. Utility Model Content

[0030] The mixing tank 1 is provided with two feed hoppers 15 , and each of the feed hoppers 15 is rotatably provided with two shielding plates 16 .

[0031] In this embodiment, the solvent is placed from one of the feed hoppers 15 into the stirring tank 1 at the lower end of the filter plate 8, and the powdered solid raw material is placed from the other feed hopper 15 into the stirring tank 1 at the upper end of the filter plate 8, and the first motor 9 is started. The first motor 9 drives the convex column 10 to rotate. When the protruding part of the convex column 10 rotates to contact the filter plate 8, the filter plate 8 is pushed upward as the convex column 10 rotates. The filter plate 8 drives the lifting rod 6 to move upward, and the lifting rod 6 mobilizes the lifting plate 5 to move, and the spring 7 is compressed. When the convex column 10 rotates to separate from the filter plate 8, under the push of the spring 7, the filter plate 8 is pushed upward. The lifting plate 5 drives the lifting rod 6 and the filter plate 8 to move back to the original position. The operation is repeated so that the filter plate 8 vibrates, thereby filtering the solid raw materials. The raw materials passing through the filter plate 8 will enter the stirring tank 1 below the filter plate 8, and the agglomerated raw materials will be intercepted above the filter plate 8. The two hydraulic cylinders 11 are started, and the hydraulic cylinders 11 drive the crushing plate 12 to move downward. The lower end of the crushing plate 12 is provided with a plurality of crushing teeth, so that when the filter plate 8 vibrates, the crushing teeth on the crushing plate 12 cooperate to crush the agglomerated raw materials. The crushed raw materials will pass through the filter plate 8 as the filter plate 8 vibrates. When the rotating shaft 13 rotates, the rotating shaft 13 drives the plurality of stirring rods 14 to stir and mix the raw materials in the stirring tank 1. The cooling pipe 2 is connected to the external pipeline, so that the liquid nitrogen enters the cooling pipe 2 to cool the stirring tank 1.

[0032] More specifically, the solid raw material can be filtered through the vibrating filter plate 8, and then the agglomerated raw material is intercepted, and the agglomerated raw material is broken by the crushing plate moving downward and cooperating with the vibrating filter plate 8. When the solid raw material and the solvent need to be fed from the two feed hoppers 15 respectively, the shielding plate 16 rotates to open the feed hopper 15. When the feeding is completed, the shielding plate 16 is rotated in the opposite direction using the opposite method to close the feed hopper 15.

[0033] See also Figure 1-5 As an implementation method for rotating the baffle plate 16: a rotating rod 17 is fixedly provided on one side of each of the baffle plates 16, one end of each of the rotating rods 17 passes through the feed hopper 15 and is fixedly connected to a gear 18, two adjacent gears 18 are meshed and connected, and a second motor 19 is fixedly provided on one side of each of the feed hoppers 15, and a driving end of the second motor 19 extends into the feed hopper 15 and is fixedly connected to one of the baffle plates 16.

[0034] Specifically, the second motor 19 is started, and the second motor 19 drives one of the baffles 16 to rotate, and one of the baffles 16 drives the rotating rod 17 to rotate, and the rotating rod 17 drives the gear 18 to rotate. Since the two gears 18 are meshed and connected, the two gears 18 rotate in opposite directions at the same time, and the gear 18 drives the other baffle 16 to rotate through the rotating rod 17, so that the two baffles 16 rotate in opposite directions, thereby opening the feed hopper 15. When the feeding is completed, the second motor 19 reverses, so that the two baffles 16 automatically close the feed hopper 15.

[0035] See also Figure 1-5 As an implementation method for rotating the rotating shaft 13 , a third motor 20 is fixedly provided on the upper end of the mixing tank 1 , and a driving end of the third motor 20 extends into the mixing tank 1 and is fixedly connected to the rotating shaft 13 .

[0036] Specifically, the third motor 20 is started, and the third motor 20 drives the rotating shaft 13 to rotate, and the rotating shaft 13 is movably connected to the filter plate 8 .

[0037] See also Figure 1-5 As an implementation method for cleaning the inside of the mixing tank 1: four connecting arms 21 are provided on the rotating shaft 13, one end of two connecting arms 21 on the same side are fixedly connected to a first scraper 22, and the lower end of each of the first scrapers 22 is fixedly connected to a second scraper 23.

[0038] Specifically, when the rotating shaft 13 rotates, the rotating shaft 13 drives the connecting arm 21 to rotate, and the connecting arm 21 drives the first scraper 22 to rotate, so that the first scraper 22 scrapes and cleans the inner wall of the stirring tank 1, and the first scraper 22 drives the second scraper 23 to rotate, so that the second scraper 23 scrapes and cleans the bottom of the stirring tank 1, and the raw materials after scraping and cleaning will continue to be stirred and mixed in the stirring tank 1. When the anti-corrosion coating that has been stirred is discharged, the first scraper 22 and the second scraper 23 can scrape and clean the inside of the stirring tank 1, so that the anti-corrosion coating that has been scraped and cleaned can be discharged together.

[0039] In summary, when the overall equipment is in use:

[0040] When the raw materials required for the production of anti-corrosion coatings are placed in the stirring tank 1, the second motor 19 is started, and the second motor 19 drives one of the baffles 16 to rotate, and one of the baffles 16 drives the rotating rod 17 to rotate, and the rotating rod 17 drives the gear 18 to rotate. Since the two gears 18 are meshed and connected, the two gears 18 rotate in opposite directions at the same time, and the gear 18 drives the other baffle 16 to rotate through the rotating rod 17, so that the two baffles 16 rotate in opposite directions, thereby opening the feed hopper 15, placing the solvent from one of the feed hoppers 15 into the stirring tank 1 at the lower end of the filter plate 8, and placing the powdered solid raw material from the other feed hopper 15 into the stirring tank 1 at the upper end of the filter plate 8. When the feeding is completed, the second motor 19 reverses, so that the two baffles 16 automatically close the feed hopper 15.

[0041] When it is necessary to crush the agglomerated raw materials in the solid raw materials placed above the filter plate 8, the solid raw materials are placed above the filter plate 8, and the first motor 9 is started. The first motor 9 drives the convex column 10 to rotate. When the protruding part of the convex column 10 rotates to contact the filter plate 8, the filter plate 8 is pushed upward with the rotation of the convex column 10, and the filter plate 8 drives the lifting rod 6 to move upward. The lifting rod 6 mobilizes the lifting plate 5 to move, and the spring 7 is compressed. When the convex column 10 rotates to separate from the filter plate 8, the lifting plate 5 drives the lifting rod 6 and the filter plate 8 to move upward. The filter plate 8 moves back to its original position, and the operation is repeated, so that the filter plate 8 vibrates, thereby filtering the solid raw materials. The raw materials passing through the filter plate 8 will enter the mixing tank 1 below the filter plate 8, and the agglomerated raw materials will be intercepted above the filter plate 8. The two hydraulic cylinders 11 are started, and the hydraulic cylinders 11 drive the crushing plate 12 to move downward. A plurality of crushing teeth are provided at the lower end of the crushing plate 12, so that when the filter plate 8 vibrates, the crushing teeth on the crushing plate 12 cooperate to crush the agglomerated raw materials, and the crushed raw materials will pass through the filter plate 8 as the filter plate 8 vibrates.

[0042] When the raw materials in the stirring tank 1 need to be stirred, the third motor 20 is started, the third motor 20 drives the rotating shaft 13 to rotate, the rotating shaft 13 is movably connected to the filter plate 8, and the rotating shaft 13 drives the multiple stirring rods 14 to stir and mix the raw materials in the stirring tank 1. The cooling tube 2 is connected to the external pipeline, so that the liquid nitrogen enters the cooling tube 2 to cool the stirring tank 1. At the same time, the rotating shaft 13 drives the connecting arm 21 to rotate, and the connecting arm 21 drives the first scraper 22 to rotate, so that the first scraper 22 scrapes and cleans the inner wall of the stirring tank 1, and the first scraper 22 drives the second scraper 23 to rotate, so that the second scraper 23 scrapes and cleans the bottom of the stirring tank 1, and the raw materials scraped and cleaned will continue to be stirred and mixed in the stirring tank 1. When the anti-corrosion coating that has been stirred is discharged, the first scraper 22 and the second scraper 23 can scrape and clean the inside of the stirring tank 1, so that the anti-corrosion coating that has been scraped and cleaned can be discharged together.
