Description

Technical Field

[0001] This utility model relates to the field of water-based paint production technology, specifically to an anti-sedimentation stirring device for water-based paint production. Background Technology

[0002] In modern industrial production, water-based paints have gradually replaced traditional solvent-based paints and become the main product in the coatings industry due to their advantages such as environmental friendliness and low volatile organic compound (VOC) content. However, the production and use of water-based paints often face the problem of precipitation of solid components such as pigments and fillers, which not only affects the uniformity of the paint solution but may also lead to a decline in coating quality during the application process.

[0003] When water-based paints are stored for extended periods or stirred at low speeds, solid particles tend to settle at the bottom, leading to uneven composition between the upper and lower layers of the paint and affecting product performance. Furthermore, ordinary stirring devices often cause paint splattering during stirring. This splattered paint, after adhering to the container walls above the liquid level, gradually solidifies and peels off, forming solid matter that introduces impurities into the water-based paint. Therefore, designing a stirring device that effectively prevents sedimentation is crucial for improving the production quality and performance of water-based paints. Utility Model Content

[0004] The purpose of this utility model is to provide a reasonably designed anti-settling stirring device for water-based paint production, which addresses the defects and shortcomings of the existing technology and solves the aforementioned defects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: it includes a mixing tank, a feed inlet on the mixing tank, a feed cover on the feed inlet, a discharge pipe at the bottom of the mixing tank, a control valve on the discharge pipe, a scraping assembly inside the mixing tank, and a bottom mixing assembly at the bottom of the mixing tank that is drivenly connected to the scraping assembly.

[0006] Preferably, the scraping assembly includes a drive motor with a top of a mixing tank, a scraping main shaft is rotatably mounted inside the mixing tank in a vertical direction, the shaft of the drive motor is connected to the top of the scraping main shaft, several scrapers are provided on the outer side of the scraping main shaft, several connecting seats are connected to the scraping main shaft, each connecting seat has a sliding groove at its front end, and several sliding rods are connected to the rear end of each scraper, each sliding rod is slidably disposed in the sliding groove, and a spring is provided between the sliding rod and the inner wall of the sliding groove.

[0007] Preferably, the bottom stirring assembly includes a drive groove formed at the bottom of the stirring tank, the bottom end of the scraper shaft is located in the drive groove, and a drive gear is connected to the bottom of the scraper shaft. Several bottom stirring shafts are rotatably mounted at the bottom of the stirring tank, and several stirring blades are connected to the upper end of each bottom stirring shaft. A driven gear is connected to the bottom end of each bottom stirring shaft. The driven gear meshes with the drive gear, and the diameter and number of teeth of the drive gear are both larger than those of the driven gear.

[0008] Preferably, sealing rings are provided at the inner opening of the chute and at the mounting points of the scraper main shaft and the bottom stirring shaft in the mixing tank.

[0009] Preferably, all the scrapers are inclined.

[0010] Preferably, the feed cover is provided with a handle, and a sealing ring is provided on the edge of the feed cover.

[0011] The beneficial effects of this utility model after adopting the above structure are:

[0012] This device is equipped with a scraping component and a bottom stirring component. The scraping component scrapes the paint from the inner wall of the mixing tank to prevent the paint from sticking and hardening. At the same time, the bottom stirring blades continuously agitate the bottom of the paint, and the turbulence between the multiple stirring blades prevents sedimentation.

[0013] This device uses a single drive motor to drive the scraper and stirring blades, and there is a speed difference between the two. The equipment is low in cost and easy to maintain. Attached Figure Description

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] See Figure 1-Figure 2 As shown, it includes a mixing tank 1, a feed inlet on the mixing tank 1, a feed cover 2 on the feed inlet, a handle 3 on the feed cover 2, and a sealing ring on the edge of the feed cover 2. A discharge pipe 4 is provided at the bottom of the mixing tank 1, and a control valve 5 is provided on the discharge pipe 4. A scraping assembly is provided inside the mixing tank 1, and a bottom mixing assembly that is drivenly connected to the scraping assembly is provided at the bottom of the mixing tank 1.

[0022] See Figures 1-4 As shown, the scraping assembly includes a high-torque, low-speed drive motor 6 located at the top of the mixing tank 1. A scraping main shaft 7 is rotatably mounted inside the mixing tank 1 in a vertical direction. The shaft of the drive motor 6 is connected to the top of the scraping main shaft 7. Several scraper blades 8 are provided on the outer side of the scraping main shaft 7. All scraper blades 8 are inclined. Several connecting seats 9 are connected to the scraping main shaft 7. Each connecting seat 9 has a sliding groove 10 at its front end. Several sliding rods 11 are connected to the rear end of each scraper blade 8. Each sliding rod 11 is slidably disposed in the sliding groove 10, and a spring 12 is provided between the sliding rod 11 and the inner wall of the sliding groove 10.

[0023] The bottom mixing assembly includes a drive groove 14 located at the bottom of the mixing tank 1. The bottom end of the scraper shaft 7 is located in the drive groove 14, and a drive gear 15 is connected to the bottom of the scraper shaft 7. Several bottom mixing shafts 17 are rotatably mounted at the bottom of the mixing tank 1. Several mixing blades 18 are connected to the upper end of each bottom mixing shaft 17. A driven gear 16 is connected to the bottom end of each bottom mixing shaft 17. The driven gear 16 meshes with the drive gear 15. The diameter and number of teeth of the drive gear 15 are both larger than those of the driven gear 16.

[0024] As an optimized solution of this utility model, a drive motor 6 is set to drive the scraper shaft 7 to rotate, which in turn drives the scraper 8 to rotate through the connecting seat 9 and the slide rod 11, scraping off the paint adhering to the inner wall of the mixing tank 1, preventing local paint solidification caused by long-term adhesion. At the same time, the spring 12 pushes the scraper 8 outward in the slide groove 10 to keep the scraper 8 in contact with the inner wall of the mixing tank 1, preventing the scraper 8 from wearing down due to long-term use and reducing scraping efficiency. While the scraper shaft 7 rotates, it drives the drive gear 15 to rotate, which in turn drives the driven gear 16 to rotate, thereby driving the bottom stirring shaft 17 to rotate, stirring the paint at the bottom of the mixing tank 1. The array of stirring blades 18 rotate synchronously, causing the paint to generate turbulence, thereby ensuring uniform material distribution of the paint and preventing sedimentation. Due to the difference in the number of teeth, the drive gear 15 drives the driven gear 16 to rotate, which will produce an acceleration effect, making the rotation speed of the bottom stirring shaft 17 higher than that of the scraper 8.

[0025] See Figures 1-4 As shown, sealing rings 13 are provided at the inner opening of the chute 10 and at the mounting points of the scraper shaft 7 and the bottom stirring shaft 17 in the mixing tank 1.

[0026] As an optimized solution of this utility model, a sealing ring 13 is provided to ensure the sealing of the interface and prevent paint from entering.

[0027] The usage process of this utility model:

[0028] First, open the feed cover 2 and add the material. Then close the feed cover 2 to start the drive motor 6. The drive motor 6 drives the scraper 8 and the bottom stirring shaft 17 to rotate. The high-speed rotating bottom stirring shaft 17 quickly stirs the paint in the bottom layer to prevent sedimentation, while the scraper 8 scrapes the paint off the inner wall of the mixing tank 1. Then open the control valve 5 and the feed cover 2 to maintain the air pressure balance inside and outside the mixing tank 1, and the paint can be discharged from the discharge pipe 4.
