Description

Technical Field

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

[0002] Color paste is a semi-finished product made by dispersing pigments or pigments and fillers in paint.

[0003] Currently, Chinese utility model patent CN221244692U discloses an anti-sedimentation device for pigment paste production. Existing pigment pastes often experience sedimentation during post-production storage, resulting in liquid stratification. However, existing pigment paste storage tanks typically only allow for basic stirring. Due to the unidirectional stirring, it's difficult to effectively and quickly mix the pigment paste, often requiring a long mixing time, thus impacting efficiency. Furthermore, the stirring process only mixes the current layer of pigment paste, failing to effectively move the bottom layer to the top layer to achieve uniform mixing, thereby reducing the overall mixing effect. Utility Model Content

[0004] The purpose of this invention is to provide an anti-sedimentation device for pigment production, which has the advantages of improving the efficiency of pigment mixing and facilitating the transfer of bottom pigment to top for circulation and mixing.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a sedimentation prevention device for pigment production, comprising a storage tank, a motor bolted to the top of the storage tank, a rotating shaft rotatably connected to the output end of the motor, connecting cylinders welded to both sides of the surface of the storage tank, an auger rotatably connected inside the connecting cylinder, a first transmission gear and a second transmission gear respectively bolted to the top of the rotating shaft and the auger, toothed synchronous belts meshing on the surfaces of the first transmission gear and the second transmission gear, and circulation ports opened at the top and bottom of the connecting cylinder near the storage tank.

[0006] Using the above technical solution, a motor drives an auger to rotate, lifting the pigment paste from the bottom of the storage tank to the top and discharging it into the tank through a circulation port. This allows the pigment paste stored in the tank to continuously circulate from the bottom to the top, effectively preventing sedimentation at the bottom. During the mixing process, the motor-driven mixing rod engages with the first bevel gear, causing the mixing rod to rotate a second time, ensuring rapid mixing and improving the efficiency of pigment paste mixing.

[0007] The present invention is further configured such that: a fixed rod welded to the storage tank is rotatably connected to the bottom of the rotating shaft; a mixing rod is rotatably connected to both sides of the surface of the rotating shaft; a first bevel gear is fixedly sleeved on the surface of the fixed rod; and a second bevel gear meshing with the first bevel gear is bolted to one end of the mixing rod near the fixed rod.

[0008] By adopting the above technical solution, the rotating shaft can drive the mixing rod to rotate axially and radially, thereby enabling the pigment paste to be mixed quickly.

[0009] The present invention is further configured such that a feeding valve and a discharging valve are respectively fixedly connected to the top and bottom of the storage tank.

[0010] Using the above technical solution, the pigment paste can be added to or discharged into the storage tank through the feeding valve and the discharge valve.

[0011] The present invention is further configured such that support legs are bolted to the four corners of the bottom of the storage tank.

[0012] The above technical solution is used to support the storage tank and improve the stability of pigment storage.

[0013] The present invention is further configured such that an observation window is opened and bolted to one side of the surface of the storage tank.

[0014] The above technical solution facilitates the observation of the storage status and quantity of pigments inside the storage tank.

[0015] The present invention is further configured such that: the surfaces of the fixing rod and the mixing rod are both fixedly fitted with sealing rings that are slidably connected to the rotating shaft.

[0016] By adopting the above technical solution, the sealing performance is improved, preventing the pigment from seeping into the interior of the rotating shaft and thus affecting the rotation of the rotating shaft.

[0017] The present invention is further configured such that auxiliary rods are welded to both sides of the surface of the mixing rod.

[0018] By adopting the above technical solution, the mixing effect of the mixing rod's rotation on the color paste is improved.

[0019] In summary, this utility model has the following beneficial effects:

[0020] 1. A motor drives an auger to rotate, lifting the pigment from the bottom of the storage tank to the top and discharging it back into the tank through a circulation port. This ensures a continuous flow of pigment from the bottom to the top, effectively preventing it from settling at the bottom.

[0021] 2. During the process of stirring the color paste by the motor-driven mixing rod, the mixing rod utilizes the meshing of the second bevel gear with the first bevel gear. This causes the mixing rod to rotate a second time, allowing the color paste to be quickly mixed and improving the efficiency of mixing the color paste. Attached Figure Description

[0027] The present invention will be further described in detail below with reference to the accompanying drawings. Example 1

[0028] refer to Figure 1 , Figure 2 , Figure 3 A sedimentation prevention device for pigment production includes a storage tank 1. A motor 2 is bolted to the top of the storage tank 1. The output end of the motor 2 is bolted to a rotating shaft 5 rotatably connected to the storage tank 1. Connecting cylinders 3 are welded to both sides of the surface of the storage tank 1. An auger 4 is rotatably connected inside the connecting cylinders 3. A first transmission gear 6 and a second transmission gear 7 are bolted to the top of the rotating shaft 5 and the auger 4, respectively. Toothed synchronous belts 8 mesh on the surfaces of the first transmission gear 6 and the second transmission gear 7. Circulation ports 9 are opened at the top and bottom of the connecting cylinders 3 near the storage tank 1. The motor 2 drives the auger 4 to rotate, causing the auger 4 to lift the pigment from the bottom of the storage tank 1 to the top and discharge it into the storage tank 1 through the circulation ports 9. This allows the pigment stored in the storage tank 1 to be continuously transported from the bottom to the top for circulation, effectively preventing the pigment from settling at the bottom.

[0029] refer to Figure 1 , Figure 2The top and bottom of the storage tank 1 are respectively fixedly connected to a feeding valve 14 and a discharge valve 15. Color paste can be added to or discharged into the storage tank 1 through the feeding valve 14 and the discharge valve 15.

[0030] refer to Figure 1 , Figure 2 Support legs 16 are bolted to the four corners of the bottom of storage tank 1. These legs support storage tank 1 and improve the stability of pigment storage.

[0031] refer to Figure 1 An observation window 17 is provided on one side of the surface of storage tank 1. This allows for easy observation of the storage status and quantity of pigments inside storage tank 1.

[0032] Brief description of the usage process: By turning on the motor 2, the first transmission gear 6 and the second transmission gear 7 mesh with the toothed synchronous belt 8, so that as the motor 2 drives the rotating shaft 5 to rotate, the auger 4 rotates synchronously inside the connecting cylinder 3. Then, the rotation of the auger 4 lifts the pigment from the bottom of the storage tank 1 through the circulation port 9, and then flows back into the storage tank 1 through the circulation port 9 at the top for circulation. Example 2

[0033] refer to Figure 1 , Figure 2 , Figure 4 A device for preventing sedimentation in pigment paste production includes a rotating shaft 5 with a fixed rod 10 welded to a storage tank 1 rotatably connected to its bottom. Mixing rods 11 are rotatably connected to both sides of the rotating shaft 5. A first bevel gear 12 is fixedly sleeved on the surface of the fixed rod 10. A second bevel gear 13, meshing with the first bevel gear 12, is bolted to one end of the mixing rod 11 near the fixed rod 10. During the mixing process, driven by a motor 2, the mixing rod 11 engages with the first bevel gear 12 via the second bevel gear 13. This causes the mixing rod 11 to rotate a second time, allowing for rapid mixing of the pigment paste and improving the efficiency of mixing.

[0034] refer to Figure 2 , Figure 4 Both the fixing rod 10 and the mixing rod 11 are fitted with sealing rings 19 that are slidably connected to the rotating shaft 5. This improves the sealing performance and prevents the pigment from seeping into the interior of the rotating shaft 5, thus affecting the rotation of the rotating shaft 5.

[0035] refer to Figure 2 , Figure 4 Auxiliary rods 18 are welded to both sides of the surface of the mixing rod 11. This improves the mixing effect of the mixing rod 11 on the pigment paste.

[0036] Brief description of the usage process: The motor 2 drives the rotating shaft 5 to rotate, which in turn drives the mixing rod 11 to rotate and mix the color paste. Then, as the rotating shaft 5 rotates on the surface of the fixed rod 10, the mixing rod 11 uses the second bevel gear 13 to mesh with the fixed first bevel gear 12, thereby causing the mixing rod 11 to rotate itself and thus mix the color paste a second time.
