Description

Technical Field

[0001] This utility model relates to the field of mixing tank technology, and specifically to a mixing tank for polyurethane resin processing. Background Technology

[0002] Polyurethane resin is a polymer material produced by the polymerization reaction of isocyanate and polyol. Its molecular structure contains urethane groups. Polyurethane coatings can be used for coating various substrates such as metal, wood, and plastic, providing good protection and decorative effects.

[0003] In the processing and production of polyurethane resin, it is necessary to ensure that isocyanate and polyol are in full contact during the mixing process to ensure that the subsequent polymerization reaction proceeds uniformly. Currently, when mixing polyurethane resin, paddle or spiral agitators are usually used for mechanical stirring. However, when the mixing is uneven, it can lead to local reactions that are too fast or too slow, resulting in problems such as bubbles, layering, and performance defects. Current mixing tanks are not convenient for real-time monitoring of the mixing status of polyurethane resin at different locations, which can easily affect the subsequent mixing effect.

[0034] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0035] like Figures 1-4As shown, this embodiment proposes a mixing tank for polyurethane resin processing, including a tank body 1, a feed inlet, stirring blades 2, mixing strips 3, mixing components, a detection tube 4, and a collection hopper 5. Two feed inlets are symmetrically located at the top of the tank body 1, allowing for uniform feeding of polyurethane resin raw materials. A sealing plug 15 is detachably connected to the feed inlet, improving the sealing performance of the tank body 1. A pull ring 16 is fixedly connected to the top of the sealing plug 15; pulling the sealing plug 15 through the pull ring 16 exposes the feed inlet, facilitating the feeding of polyurethane resin. Multiple stirring blades 2 are arranged in an array rotating within the tank body 1, staggered from top to bottom. All stirring blades 2 are S-shaped, increasing the contact area between the stirring blades 2 and the polyurethane resin, thus improving the uniform feeding of the polyurethane resin. To improve the mixing effect of the resin, multiple mixing strips 3 are configured, each rotating and installed between multiple stirring blades 2. All mixing strips 3 are arc-shaped, increasing the mixing range of the polyurethane resin. A mixing assembly is installed between the multiple mixing strips 3. Multiple detection tubes 4 are equidistantly connected to one side of the tank 1. A collection hopper 5 is installed at an angle below each detection tube 4. Each detection tube 4 is equipped with a detection valve. Opening these valves allows the polyurethane resin mixture at different locations within the tank 1 to be discharged and enter the corresponding collection hopper 5 for testing. A discharge pipe 17 is connected to the bottom of the tank 1, and a discharge valve is installed on the discharge pipe 17. Opening the discharge valve allows the polyurethane resin mixture within the tank 1 to be discharged through the discharge pipe 17.

[0036] refer to Figure 2 as well as Figure 3 The mixing assembly includes a protective cylinder 6, a first motor 7, connecting columns, mixing rods 8, a main gear 9, driven wheels 10, and rotating wheels 11. The protective cylinder 6 is fixedly connected to the outer wall of the tank body 1. The first motor 7 is installed on one side of the protective cylinder 6, and the output end of the first motor 7 is connected through the protective cylinder 6. Multiple connecting columns are provided, and multiple connecting columns are rotatably connected to the inner wall of the protective cylinder 6. Multiple mixing rods 8 are provided, and multiple mixing rods 8 are rotatably connected through the protective cylinder 6 and the tank body 1. Multiple mixing strips 3 are fixedly connected to multiple mixing rods 8 respectively. The main gear 9 is fixedly connected to the output end of the first motor 7. Multiple driven wheels 10 are provided, and multiple driven wheels 10 are fixedly connected to multiple mixing rods 8 respectively. Multiple rotating wheels 11 are provided, and multiple rotating wheels 11 are installed on multiple connecting columns respectively, and multiple rotating wheels 11 mesh with the main gear 9 and multiple driven wheels 10 respectively.

[0037] When the test is completed and the polyurethane resin in tank 1 needs to be stirred and mixed again, the first motor 7 is started. Through the meshing of the main gear 9, multiple driven wheels 10 and multiple rotating wheels 11, multiple connecting columns and multiple mixing rods 8 are rotated simultaneously. This allows multiple mixing rods 8 to drive multiple mixing strips 3 to rotate simultaneously, thereby stirring and mixing the polyurethane resin between multiple mixing plates 2 again, improving the mixing effect of polyurethane resin.

[0038] refer to Figure 1 , Figure 3 as well as Figure 4 A second motor 12 is installed at the top of the tank body 1. The output end of the second motor 12 is connected through the tank body 1, and a stirring column 13 is fixedly connected between the output end of the second motor 12 and multiple stirring blades 2.

[0039] When the second motor 12 is started, the stirring column 13 can drive multiple stirring blades 2 to rotate, so that the multiple stirring blades 2 can uniformly stir and mix the polyurethane resin in the tank 1, thereby improving the mixing effect of the polyurethane resin.

[0040] refer to Figure 4 Multiple stirring bars 14 are connected in a circular array on the lower side of the stirring column 13, and the multiple stirring bars 14 are all inclinedly connected to the stirring column 13.

[0041] When the stirring column 13 rotates, it can drive multiple stirring bars 14 to rotate simultaneously, so as to stably stir the polyurethane resin raw material on the lower side of the tank 1, thereby improving the uniform stirring effect of the polyurethane resin in the tank 1.

[0042] In this embodiment, when it is necessary to mix the polyurethane resin raw materials in the tank 1, the second motor 12 is started, causing the stirring column 13 to drive multiple stirring blades 2 and multiple stirring strips 14 to rotate simultaneously, so that the multiple stirring blades 2 and multiple stirring strips 14 can uniformly stir and mix the polyurethane resin raw materials in the tank 1. When it is necessary to test the polyurethane resin mixture at a certain location, the corresponding detection valve is opened, so that the polyurethane resin mixture at this location is discharged through the detection pipe 4 into the collection hopper 5, which can detect the degree of mixing of polyurethane resin. After the test is completed, when it is necessary to mix the polyurethane resin raw materials in the tank 1 again, the first motor 7 is started, causing multiple mixing rods 8 to rotate through the meshing of the main gear 9, multiple driven wheels 10 and multiple rotating wheels 11, so that the multiple mixing strips 3 can stir and mix the polyurethane resin raw materials again, thereby improving the mixing effect of the polyurethane resin raw materials.

[0043] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
