Description

Technical Field

[0001] The utility model relates to the technical field of storage tanks, in particular to a storage tank for preparing polyurethane soft foam. Background Art

[0002] Polyurethane soft foam is a kind of foam made of polyurethane material, which has the characteristics of lightness, softness and good elasticity. This foam is usually used in the manufacture of seats, mattresses, baby mattresses, furniture, etc. Because of its good comfort and support, it is widely used in various household and industrial products. The preparation of polyurethane foam usually requires mixing a variety of raw materials together, including polyether or polyester polyols, isocyanates, additives, etc. In the storage tank, the mixed raw materials can react to form polyurethane foam. The storage tank plays a vital role in the preparation process of polyurethane soft foam, which can ensure that the raw materials are evenly mixed, fully reacted, and provide a safe operating environment.

[0003] Traditional storage tanks for preparing polyurethane soft foam usually consist of a feed pipe and a tank body. The tank body itself is relatively sturdy, and the feed inlet of the storage tank usually needs to be sealed with screws to ensure that the raw materials will not leak or be contaminated by external impurities during storage, and to ensure that the connection between the feed pipe and the tank body is firm and sealed.

[0004] However, the structure of traditional storage tanks is relatively simple, and the opening and closing of the feed port must be controlled manually by screws. The process is too cumbersome and will waste a lot of time and unnecessary manpower. In this process, external impurities and dust in the air may enter the storage tank. These impurities and pollutants may affect the quality of the raw materials, thereby causing a decline in product quality and affecting the practicality of the storage tank. Utility Model Content

[0026] Specifically, when using the storage tank, the operator can move the connection frame 13 through the output end of the electric push rod 12. The connection frame 13 is acted upon by a force, guiding the slider 24 fixedly connected to the side wall to slide in the slide groove 23. At the same time, the connection frame 13 will also drive the internally rotatably connected limit column 1 8 and the limit column 2 10 to rotate in opposite directions. The movement of the limit column 1 8 drives the rotating shaft 7 fixedly connected at the bottom to start rotating, and the movement of the rotating shaft 7 is transmitted to one of the sleeves 6 rotatably connected to the outer wall, thereby affecting the rotation of the first opening and closing plate 4. At the same time, the movement of the limit column 2 10 guides the other hollow column 9 fixedly connected at the bottom to rotate in the opposite direction, and the movement of the hollow column 9 drives another sleeve 6 to rotate on the outer wall of the rotating shaft 7, so that the second opening and closing plate 5 rotates in the opposite direction of the first opening and closing plate 4. In this way, the storage tank can be opened quickly to achieve a fast and effective feeding operation.

[0027] Reference Figure 1 and Figure 5A fixing frame 14 is provided at the bottom of the support frame 1, a motor 21 is fixedly connected to one side of the fixing frame 14, an external gear 22 is fixedly connected to the output end of the motor 21, the external gear 22 is meshed with the bevel gear 20, and the bottom of the rotating wheel 18 is rotatably connected to the bevel gear 20, and the bevel gear 20 is rotatably connected to the inside of the support frame 1.

[0028] Specifically, during the storage process, if the material needs to be stirred, the operator can start the stirring device through the output end of the motor 21. The output of the motor 21 drives the outer gear 22 to start rotating, and the bevel gear 20 meshing with the outer gear 22 also starts to rotate. The power of the bevel gear 20 is transmitted to the support frame 1 connected to the outer wall, and then guides the internally connected tank body 2 to rotate, thereby shaking the material inside the tank body 2 and achieving the effect of rotating the tank body 2.

A rotating wheel 2 18 is rotatably connected to the top of the support frame 1, and a synchronous belt 19 is provided between the rotating wheel 2 18 and the rotating wheel 1 17.

[0030] Specifically, at the same time, the bevel gear 20 will also drive the rotating wheel 2 18 connected to the top to start rotating, and the rotating wheel 2 18 drives the rotating wheel 1 17 to rotate synchronously through the synchronous belt 19 provided on the outer wall. The movement of the rotating wheel 17 causes the rotating column 15 connected to the inner rotation to start rotating inside the tank body 2, and the movement of the rotating column 15 further drives the stirring blade 16 fixedly connected to the outer wall to rotate. In this way, the stirring blade 16 further stirs the material inside the tank body 2 to ensure that the material is fully mixed and evenly mixed, so that the stirring process is efficient and even.

[0031] Working principle: when using the storage tank, the connection frame 13 can be moved by the output end of the electric push rod 12, and the connection frame 13 is forced to drive the slider 24 fixedly connected to the side wall to slide inside the slide groove 23, and at the same time, the connection frame 13 also drives the internal rotationally connected limit column 1 8 and the limit column 2 10 to rotate in opposite directions, and the limit column 1 8 is forced to drive the rotating shaft 7 fixedly connected to the bottom to rotate, and the rotating shaft 7 is forced to drive one of the sleeves 6 connected to the outer wall rotation to rotate, and the sleeve 6 is forced to drive the first opening and closing plate 4 fixedly connected to the outer wall to rotate, and at the same time, the limit column 2 10 is forced to drive the hollow column 9 fixedly connected to the bottom to rotate in the opposite direction, and the hollow column 9 is forced to drive another sleeve 6 fixedly connected to the bottom to rotate on the outer wall of the rotating shaft 7, so that the second opening and closing plate 5 rotates in the opposite direction of the first opening and closing plate 4, thereby achieving the goal that the storage tank can be quickly opened when feeding.
