Description

Technical Field

[0001] This utility model relates to the field of coating production technology, and more specifically, to an anti-settling device for water-based coating production. Background Technology

[0002] Water-dilutable coatings refer to coatings formulated with post-emulsified emulsions as film-forming agents. Solvent-based resins are dissolved in organic solvents, and then, with the aid of emulsifiers and vigorous mechanical stirring, the resins are dispersed in water to form an emulsion. This is called a post-emulsified emulsion, and the resulting coating can be diluted with water during application. During storage, prolonged exposure to water-based coatings can easily cause some of the stored coating to precipitate within the container.

[0003] For example, a utility model patent with publication number CN217042356U discloses an anti-settling device for water-based coating production, including a coating tank. The top of the coating tank has a feed inlet, and a first drive motor is installed at the top of the coating tank. The output end of the first drive motor is fixedly connected to a first drive shaft, and a first anchor-type agitator is installed on the first drive shaft. A second drive motor is installed at the bottom of the coating tank, and the output end of the second drive motor is fixedly connected to a second drive shaft, and a second anchor-type agitator is installed on the second drive shaft. An installation base is installed at the center of the inner side wall of the coating tank, and a partition plate is inserted into the installation base. The side of the coating tank has a discharge port.

[0004] The above-mentioned patent has the following problems when used: the current water-based coating production equipment mainly uses agitators to stir to prevent water-based coatings from settling. However, the material settling at the bottom of the container is not easy to be stirred up and rise, so the agitator cannot completely disperse the settling material, resulting in poor anti-settling effect. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a technical solution that can address the high risk of sedimentation in water-based coating production equipment.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an anti-settling device for water-based coating production, comprising a coating tank, a centrifugal disc rotatably connected to the bottom of the coating tank, a servo motor fixedly connected to the bottom of the coating tank, the output shaft of the servo motor passing through the coating tank and fixedly connected to the centrifugal disc, a conveying pipe fixedly connected to the top of the coating tank, a discharge pipe provided on the outer surface of the conveying pipe, a feed pipe provided at the bottom of the conveying pipe, a drive shaft provided inside the conveying pipe, a spiral blade and a stirring rod fixedly connected to the drive shaft, and a heating element fixedly connected to the outer surface of the conveying pipe.

[0007] In a preferred embodiment, a second inlet pipe is provided at the top of the paint tank, and a second outlet pipe is provided at the bottom of the outer surface of the paint tank.

[0008] In a preferred embodiment, a stirring plate is fixedly connected to the top of the centrifuge disc.

[0009] In a preferred embodiment, one end of the drive shaft is fixedly connected to a key shaft, and the top of the centrifugal disc is fixedly connected to a transmission seat for key shaft insertion.

[0010] In a preferred embodiment, a hanger is provided at the other end of the drive shaft. The hanger is bolted to the top of the paint tank, and an extension column is fixedly connected to the bottom of the hanger. The drive shaft is rotatably connected to the extension column.

[0011] In a preferred embodiment, a sealing seat is fixedly connected to the outer surface of the extension column, the top end of the delivery pipe is flush with the top of the paint tank, and the sealing seat is inserted into the delivery pipe.

[0012] In a preferred embodiment, a lifting ring is fixedly connected to the hanger.

[0013] In a preferred embodiment, an insulation box is fixedly connected to the outer surface of the delivery pipe, and the heating element is located inside the insulation box.

[0014] The technical effects and advantages of this utility model are as follows: 1. This anti-sedimentation device for water-based coating production uses a centrifugal disc installed at the bottom of the coating tank. The rotating centrifugal disc, in conjunction with a stirring plate, centrifuges and throws out sediment, promoting its upward movement. This facilitates the dispersion of sediment. Furthermore, the spiral blades of the screw conveyor suck in the sediment and transport it upward. Simultaneously, a stirring rod agitates the material during the conveying process. This continuous pumping of water-based coating from bottom to top within the coating tank ensures thorough and uniform dispersion of the water-based coating, effectively preventing sedimentation in water-based coating production.

[0015] 2. In this anti-settling device for water-based coating production, one end of the drive shaft can be connected to the centrifugal disc by insertion transmission, and the other end of the drive shaft can be connected to the coating tank by hanger bolts. In this way, the drive shaft and its spiral blades and stirring rods can be flexibly assembled in the conveying pipe, which is convenient for maintenance.

[0016] 3. The anti-settling device for water-based coating production uses a heating element installed on the outer surface of the conveying pipe. The heating element can heat the material circulating in the conveying pipe, which can raise the temperature of the water-based coating, reduce its viscosity, and improve its fluidity. This can improve the efficiency of stirring and pumping, and ensure that the coating components are evenly dispersed. Attached Figure Description

[0020] The following specific embodiments illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0021] See also Figures 1-5 This utility model provides an anti-settling device for water-based coating production. It is used for water-based coating production and includes a coating tank 1. The top of the coating tank 1 is provided with a feed pipe 2 10 and the bottom of the outer surface of the coating tank 1 is provided with a discharge pipe 2 11.

[0022] Both the feed pipe 210 and the discharge pipe 211 are connected to the paint tank 1. The feed pipe 210 is positioned to facilitate the addition of water-based paint production raw materials into the paint tank 1. The discharge pipe 211 should be equipped with a valve and can be used to discharge water-based paint from the paint tank 1. In this application, the paint tank 1 is equipped with an explosion-proof observation window, which is located at the bottom of the outer surface of the paint tank 1. Its position allows for observation of the sedimentation status of the material inside the paint tank 1.

[0023] In this embodiment: a centrifugal disc 2 is rotatably connected to the bottom of the paint tank 1, and a servo motor 21 is fixedly connected to the bottom of the paint tank 1. The output shaft of the servo motor 21 passes through the paint tank 1 and is fixedly connected to the centrifugal disc 2.

[0024] The purpose of the centrifugal disc 2 being placed at the bottom of the paint tank 1 is to receive the sediment. The centrifugal disc 2 is driven to rotate by the servo motor 21, and the sediment on it can be centrifuged and thrown out, which can promote the flow of the sediment so as to stir and disperse it.

[0025] In this embodiment, a stirring plate 12 is fixedly connected to the top of the centrifuge disc 2.

[0026] Multiple stirring plates 12 are provided, arranged in a ring, with one side of each stirring plate 12 being arc-shaped. When the centrifugal disc 2 rotates, the stirring plates 12 can agitate the sediment and push it upward, making it easier to disperse the sediment as it rises.

[0027] In this embodiment: a conveying pipe 3 is fixedly connected to the inner top of the paint tank 1, a discharge pipe 4 is provided on the outer surface of the conveying pipe 3, a feed pipe 5 is provided at the bottom of the conveying pipe 3, a drive shaft 6 is provided inside the conveying pipe 3, and a spiral blade 7 and a stirring rod 8 are fixedly connected to the drive shaft 6.

[0028] Multiple stirring rods 8 are provided. When the drive shaft 6 is rotated, the sediment on the centrifugal disc 2 can be lifted up. The end of the feed pipe 5 can suck up the lifted sediment under negative pressure. The rotation of the drive shaft 6 can synchronously drive the spiral blades 7 and stirring rods 8 to rotate. The rotation of the spiral blades 7 can continuously pump the water-based paint at the bottom of the paint tank 1 upward. By pumping the water-based paint from bottom to top, the sediment can be effectively dispersed. In addition, the stirring rods 8 can be used to stir the paint in the conveying pipe 3, which can ensure the uniformity of the water-based paint mixing concentration.

[0029] In this embodiment: a key shaft 13 is fixedly connected to one end of the drive shaft 6, and a transmission seat 14 for inserting the key shaft 13 is fixedly connected to the top of the centrifugal disk 2.

[0030] After the drive shaft 6 extends into the conveying pipe 3, the key shaft 13 can be inserted into the transmission seat 14. In this way, when the centrifugal disc 2 rotates, the drive shaft 6 on the key shaft 13 can be driven through the transmission seat 14, so that the spiral blade 7 and the stirring rod 8 can rotate synchronously.

[0031] In this embodiment: a hanger 15 is provided at the other end of the drive shaft 6. The hanger 15 is bolted to the top of the paint tank 1. An extension column 16 is fixedly connected to the bottom of the hanger 15. The drive shaft 6 is rotatably connected to the extension column 16. A sealing seat 17 is fixedly connected to the outer surface of the extension column 16. The top end of the delivery pipe 3 is flush with the top of the paint tank 1. The sealing seat 17 is inserted into the delivery pipe 3.

[0032] The sealing seat 17 is made of rubber. When assembling the drive shaft 6, the drive shaft 6 can be placed into the delivery pipe 3 until the key shaft 13 and the transmission seat 14 are inserted and matched. Then the sealing seat 17 can be inserted into the delivery pipe 3 to achieve partial sealing of the end of the delivery pipe 3. Finally, the hanger 15 can be fastened to the top of the paint tank 1 with bolts. When controlling the rotation of the drive shaft 6, the extension column 16 can support the drive shaft 6 to achieve stable rotation.

[0033] In this embodiment, a lifting ring 18 is fixedly connected to the hanger 15.

[0034] Since the hanger 15 is connected to the paint tank 1 by bolts and can be easily disassembled, the lifting ring 18 can be used with the existing electric hoist to pull out the drive shaft 6 in the delivery pipe 3, which makes it convenient to maintain the drive shaft 6 and its structure.

[0035] In this embodiment: a heating element 9 is fixedly connected to the outer surface of the conveying pipe 3, and a heat preservation box 19 is fixedly connected to the outer surface of the conveying pipe 3, with the heating element 9 located inside the heat preservation box 19.

[0036] The heating element 9 uses a ceramic heating coil, which can be coiled along the length of the paint tank 1. The ceramic heating coil can be connected to a thermostat using existing wiring technology. The thermostat can be used to control the heating of the ceramic heating coil at a constant temperature. The outer surface of the insulation box 19 is made of waterproof material, and the inner surface of the insulation box 19 is made of insulation material. The insulation box 19 can increase the heat preservation of the ceramic heating coil. The ceramic heating coil heats the delivery pipe 3, so the water-cooled paint delivered in the delivery pipe 3 can be heated. Heating can increase the temperature of the water-based paint, reduce viscosity, improve fluidity, and ensure uniform dispersion of paint components.

[0037] The servo motor 21 and the temperature controller mentioned in the text are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that performs control, and the existing publicly available power connection technology will not be described in detail in the text.
