Description

Technical Field

[0001] This utility model relates to a homogenizing device for latex paint. Background Technology

[0002] Latex paint is a type of organic coating. It is a water-based coating made by adding pigments, fillers and various additives to synthetic resin emulsion as a base. The production process of latex paint mainly includes raw material preparation, mixing and homogenization, grinding and refining and paint matching. The homogenization process of latex paint is mainly achieved by stirring equipment. The purpose is to ensure that the components in the latex paint are fully mixed and uniform, and to avoid sedimentation or separation.

[0003] The existing mixing equipment has a hollow internal structure, where the latex paint concentrate is concentrated. The stirring rod cannot effectively disperse the latex paint concentrate, preventing the stirring area from reaching the center of the latex paint concentrate. Furthermore, the latex paint concentrate can only rotate circumferentially inside the tank and cannot flow vertically, resulting in poor homogenization. This can only be alleviated by extending the stirring time, which is both time-consuming and affects production efficiency, thus requiring further improvement. Utility Model Content

[0004] In view of the current state of the prior art, the technical problem to be solved by this utility model is to provide a latex paint homogenizing device that can not only stir the latex paint concentrate in sections, but also drive the latex paint concentrate to flow upward or downward, thereby improving the homogenization effect, shortening the stirring time and improving the production efficiency.

Each blade unit is located inside a corresponding inverted conical stirring zone. The blade unit includes at least two blades fixed on the outer wall of the drive rod and evenly arranged at equal angles along the circumferential direction. Correspondingly, each inverted conical partition ring has several opening slots evenly distributed at equal angles along the circumferential direction on its inner circumferential surface. The number of opening slots on each inverted conical partition ring is an integer multiple of the number of blades in each blade unit. Each blade has an upwardly inclined extension at its end, and each extension is located below a corresponding inverted conical partition ring. The inclination of the extension matches the inclination of the inverted conical partition ring and the inclination of the inner wall of the bottom of the vessel.

[0006] Preferably, the depth of the opening groove is matched with the radial length of the extension so that the end edge of the extension does not exceed the bottom inner wall of the opening groove.

[0007] Preferably, each blade has an inclined bend formed on the upper and lower edges of its root, respectively, and the two bends on the same blade are centrally symmetrical and located on the inner side of each inverted conical separator ring.

[0017] To keep the following description of the embodiments of this utility model clear and concise, detailed descriptions of known functions and known components are omitted.

[0018] like Figures 1-3 As shown, a homogenizing device for latex paint includes a movable frame 1, a platform 2 horizontally fixed to the top of the movable frame 1, a vessel body 11 vertically inserted and fixed in the platform 2, a detachable vessel cover 12 fixed to the top opening of the vessel body 11, and a homogenizing mechanism 3 disposed between the vessel body 11 and the vessel cover 12. The homogenizing mechanism 3 includes a drive rod 33 that is vertically and movably connected to the center of the vessel lid 12, a plurality of inverted conical partition rings 32 that are horizontally fixed on the inner wall of the vessel body 11 and arranged at equal intervals from top to bottom, and a plurality of blade units that are arranged on the drive rod 33 and distributed at equal intervals from top to bottom. The lower end of the drive rod 33 extends concentrically into the interior of the vessel body 11, and the number of blade units is the same as the number of inverted conical partition rings 32. An inverted conical stirring zone 34 is formed between any two adjacent inverted conical separating rings 32 and between the lowest inverted conical separating ring 32 and the bottom inner wall of the vessel body 11. Each blade unit is located inside a corresponding inverted conical stirring zone 34. The blade unit includes at least two blades 31 fixed on the outer wall of the drive rod 33 and evenly arranged at equal angles along the circumferential direction. Correspondingly, each inverted conical partition ring 32 has a number of opening slots 321 evenly distributed at equal angles along the circumferential direction on its inner circumferential surface. The number of opening slots 321 on each inverted conical partition ring 32 is an integer multiple of the number of blades 31 in each blade unit. Each blade 31 has an outwardly inclined upward extension 311 at its end. Each extension 311 is located below a corresponding inverted conical partition ring 32. The slope of the extension 311 is matched with the slope of the inverted conical partition ring 32 and the slope of the inner wall of the bottom of the vessel body 11. The depth of the opening groove 321 is matched with the radial length of the extension 311 so that the end edge of the extension 311 does not exceed the bottom inner wall of the opening groove 321.

[0019] Each blade 31 has an inclined bend 312 formed on the upper and lower edges of its root, respectively. The two bends 312 on the same blade 31 are centrally symmetrical and located inside each inverted conical partition ring 32, so that the bends 312 will not contact the inverted conical partition ring 32 when rotating with the drive rod 33.

[0020] The top of the platform 2 is also provided with a lifting assembly 4. The lifting assembly 4 includes a lifting block 43 horizontally arranged above the platform 2, a top plate 41 horizontally arranged above the lifting block 43, two guide columns 42 vertically inserted and connected in the lifting block 43 and symmetrically arranged, a screw rod 44 vertically inserted and screwed in the lifting block 43, and a lifting frame 46 fixed on the lifting block 43. The upper and lower ends of each guide column 42 are fixed on the top plate 41 and the platform 2 respectively. The upper end of the screw rod 44 is rotatably inserted and connected to the top plate 41, and the lower end of the screw rod 44 is rotatably connected to the platform 2.

[0021] A power motor 13 is also fixed on the lifting frame 46. The rotating shaft of the power motor 13 is set vertically downward and concentrically fixed to the upper end of the drive rod 33.

[0022] The lifting frame 46 is also fixed with a feed pump 5. The feed pump 5 has a feed pipe 6 and a discharge pipe 7 respectively inserted into its feed port and discharge port. The end opening of the discharge pipe 7 is set vertically downward and is movably inserted into the lid 12.

[0023] Several vertically arranged dosing cylinders 8 are also interspersed and fixed in the lid 12.

[0024] A concentrically arranged handwheel 45 is also fixed to the upper end of the lead screw 44.

[0025] A vertically arranged heat preservation tank 9 is also fixed in the platform 2. A bracket 10 is fixed inside the bottom of the heat preservation tank 9. The vessel body 11 is concentrically arranged inside the heat preservation tank 9, and the bottom of the vessel body 11 is fixed to the top of the bracket 10.

[0026] A vertically arranged discharge pipe 14 is also inserted and fixed at the bottom center of the heat preservation tank 9. The upper opening of the discharge pipe 14 is sealed and inserted into the bottom center of the vessel body 11, and a discharge valve 15 is connected in series at the lower opening of the discharge pipe 14.

[0027] A liquid inlet pipe 16 is also inserted into one side of the bottom of the heat preservation tank 9, and a liquid outlet pipe 17 is also inserted into one side of the top opening of the heat preservation tank 9.

[0028] The top opening of the vessel body 11 has an outwardly circumferential flange 111, and the lower outer wall of the circumferential flange 111 is attached to the top opening of the heat preservation tank 9 to seal the top opening of the heat preservation tank 9.

[0029] Working principle: Connect the end opening of the feed pipe 6 to the container containing the latex paint concentrate. After starting the feed pump 5, the latex paint concentrate will flow into the reactor body 11 through the feed pipe 6 and the discharge pipe 7, and fall onto the top outer wall of the uppermost inverted conical partition ring 32. Then, it will flow inward along the top outer wall of the inverted conical partition ring 32 and drip downward. Some of the latex paint concentrate will drip downward through multiple opening grooves 321, which serve as diversion channels. After closing the discharge valve 15, the latex paint concentrate will accumulate in the reactor body 11 and the liquid level will gradually rise until each inverted conical stirring zone 34 is filled.

[0030] The power motor 13 is started to rotate its rotating shaft, which in turn drives each blade unit to rotate via the drive rod 33. The extension 311 on each blade 31 in each blade unit will stir the latex paint concentrate located in each inverted conical stirring zone 34 to achieve a homogenization effect. In this way, the latex paint concentrate that was originally concentrated together can be stirred in sections, thereby improving the homogenization effect.

[0031] At the same time, each blade 31 will drive two bending parts 312 to rotate synchronously during rotation. Since the two bending parts 312 on the same blade 31 are centrally symmetrical, the two bending parts 312 will drive the latex paint liquid surrounding the drive rod 33 to flow upward or downward, thereby enabling the latex paint liquid in each inverted cone stirring zone 34 to flow and mix with each other.

[0032] During the stirring process, the heating medium can be introduced into the interior of the heat preservation tank 9 through the liquid inlet pipe 16 and then discharged outward through the liquid outlet pipe 17 to achieve circulation. The heating medium inside the heat preservation tank 9 will transfer heat to the vessel body 11 and then to the latex paint concentrate through the vessel body 11.

[0033] After mixing is complete, turn off the power motor 13 to stop the rotation of each blade unit, and then open the discharge valve 15 to discharge the homogenized latex paint.

[0034] If it is necessary to inspect or clean the inside of the vessel body 11, the vessel cover 12 can be removed first and moved vertically upwards to suspend it above the vessel body 11. Since the drive rod 33 and the discharge pipe 7 are both movably connected to the center of the vessel cover 12, the vessel cover 12 can move relative to the drive rod 33 and the discharge pipe 7. Then, hold the handwheel 45 in the lifting assembly 4 and rotate it to drive the lead screw 44 to rotate synchronously. Then, according to the principle of spiral connection, the lifting block 43 is driven to move upwards along the two guide columns 42. Thus, with the help of the lifting frame 46, the power motor 13 and the feed pump 5 are driven to move upwards, thereby gradually moving the drive rod 33 and the discharge pipe 7 out of the vessel body 11.

[0035] Before the lifting frame 46 moves upward, the drive rod 33 needs to be manually rotated at a certain angle so that the extension 311 on each blade 31 is rotated to the direct under the corresponding opening slot 321. When each blade 31 moves upward with the drive rod 33, each extension 311 can pass smoothly through the corresponding opening slot 321 to avoid being blocked by the inverted conical partition ring 32. The opening slot 321 serves to facilitate disassembly.

[0036] This invention utilizes multiple inverted conical separating rings 32 to divide the latex paint concentrate into multiple inverted conical stirring zones 34 distributed sequentially from top to bottom. Simultaneously, each paddle unit performs zoned stirring of the latex paint concentrate within each inverted conical stirring zone 34, effectively dispersing the latex paint concentrate. Furthermore, the two bends 312 on each paddle 31 can drive the latex paint concentrate surrounding the drive rod 33 to flow upwards or downwards, allowing the latex paint concentrate within each inverted conical stirring zone 34 to flow and blend together, thereby improving the homogenization effect, shortening the stirring time, and increasing production efficiency.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
