Description

Technical Field

[0001] This utility model relates to the field of NVP product storage technology, and in particular to a leak-proof storage tank for NVP products. Background Technology

[0002] NVP produces widely used PVP monomers through polymerization reactions. In dyes, it can increase film strength and adhesion. NVP can also be used to prepare cosmetics, pharmaceuticals, beer settling agents, etc. NVP is also used as a sugar coating for tablets, a diluent for ultraviolet absorbers, a coating for foam hair products, and a disinfectant and bactericidal agent.

[0003] Most existing NVP product storage tanks use a lid with a sealing ring to seal the tank. The lid is located at the top of the storage tank. If the storage tank is not full, the NVP products will swing in the storage tank during transportation or movement, resulting in poor storage stability. Utility Model Content

[0004] The purpose of this utility model is to solve the following shortcomings in the prior art. Most existing NVP product storage tanks are sealed with a lid with a sealing ring. The lid is located at the top of the storage tank. If the NVP products in the storage tank are not full, the NVP products will swing in the storage tank during transportation or movement, resulting in poor storage stability. Therefore, a leak-proof storage tank for NVP products is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A leak-proof storage tank for NVP products includes a tank body and a cover plate, the cover plate being installed on the upper end of the tank body;

[0007] An installation cylinder is fixedly connected to the cover plate. Vertical rods are slidably connected to both ends of the installation cylinder. A sealing component is installed on the installation cylinder. The sealing component includes an upper circular plate, a disc, a lower circular plate, an airbag, and a rubber ring. The upper circular plate is fixedly connected between the two vertical rods. The upper circular plate is fixedly connected to the lower circular plate through the disc. The airbag is annular and fits onto the outer surface of the disc. A piston plate is slidably connected inside the installation cylinder. A flexible hose is provided between the installation cylinder and the airbag. The rubber ring fits onto the outer surface of the airbag.

[0008] Preferably, the sealing component further includes a lead screw, which is threadedly connected to the upper wall of the mounting cylinder and rotatably connected to the piston plate.

[0009] Preferably, an elliptical cylinder is fixedly connected to the mounting cylinder, and a trapezoidal block is slidably connected inside the elliptical cylinder, the trapezoidal block being rotatably connected to the lead screw.

[0010] Preferably, an extrusion plate is slidably connected to both ends of the elliptical cylinder, one end of the extrusion plate is slidably connected to the inclined surface of the trapezoidal block, and an arc-shaped groove is formed at the end of the extrusion plate away from the trapezoidal block.

[0011] Preferably, the surfaces of the two vertical rods away from the upper circular plate are respectively provided with toothed patterns.

[0012] Preferably, a glass plate is fixedly connected to the tank body.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. When the pressure plates move away from each other, they press against the teeth on the vertical rod to fix the vertical rod, as well as the upper and lower circular plates. Since the lower circular plate is on the upper side of the NVP product, it can effectively limit the NVP product, thereby reducing the swing of the NVP product when the tank is moved, so as to achieve the stable storage of the NVP product.

[0015] 2. As the gas inside the airbag increases, it expands. The expansion of the airbag can compress and stretch the rubber ring until the outer surface of the rubber ring contacts the inner wall of the tank and forms a compression, thereby achieving a better sealing effect on the NVP product inside the tank.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The terms used in this utility model, such as "upper", "lower", "left", "right", "middle" and "one", are only for clarity of description and are not intended to limit the scope of implementation of this utility model. Changes or adjustments to their relative relationships, without substantially altering the technical content, should also be considered as within the scope of implementation of this utility model.

[0023] Reference Figures 1-4 A leak-proof storage tank for NVP products includes a tank body 1 and a cover plate 3. The cover plate 3 is installed on the upper end of the tank body 1 and acts as a seal for the tank body 1. The installation relationship of the cover plate 3 to the tank body 1 is similar to that of a barrel and a lid in the prior art. A glass plate 2 is fixedly connected to the tank body 1. The glass plate 2 is part of the tank body 1 and allows the staff to see inside the tank body 1.

[0024] An installation cylinder 7 is fixedly connected to the cover plate 3. Vertical rods 4 are slidably connected to both ends of the installation cylinder 7. A sealing component is installed on the installation cylinder 7. The sealing component includes an upper circular plate 12, a disc 11, a lower circular plate 14, an airbag 16, and a rubber ring 13. The upper circular plate 12 is fixedly connected between the two vertical rods 4. The upper circular plate 12 is fixedly connected to the lower circular plate 14 through the disc 11. The airbag 16 is arranged in a ring shape and is sleeved on the outer surface of the disc 11. The inner wall of the airbag 16 is fixedly connected to the disc 11. A piston plate 10 is slidably connected inside the installation cylinder 7. A flexible hose is provided between the installation cylinder 7 and the airbag 16. The flexible hose is elastic. The rubber ring 13 is sleeved on the outer surface of the airbag 16.

[0025] An elliptical cylinder 6 is fixedly connected to the mounting cylinder 7. A trapezoidal block 8 is slidably connected inside the elliptical cylinder 6. The trapezoidal block 8 is rotatably connected to the lead screw 5. When the lead screw 5 moves downward during rotation, it can drive the trapezoidal block 8 to move downward. Extrusion plates 9 are slidably connected to both ends of the elliptical cylinder 6. One end of the extrusion plate 9 is slidably connected to the inclined surface of the trapezoidal block 8. The surfaces of the two vertical rods 4 away from the upper circular plate 12 are respectively provided with teeth. The extrusion plate 9 away from the trapezoidal block 8 is provided with an arc-shaped groove. When the extrusion plate 9 moves, it can contact the teeth on the outer wall of the vertical rod 4 through the arc-shaped groove. The extrusion plate 9 is made of rubber material and is pressed on the vertical rod 4. The friction between the extrusion plate 9 and the vertical rod 4 is relatively large.

[0026] In this invention, during use, the NVP product is first poured into the container 1, then the cover plate 3 is placed on the container 1, and the vertical rod 4 is pushed down inside the mounting cylinder 7. At the same time, the upper circular plate 12 and the lower circular plate 14 will move downward on the inner wall of the container 1. By observing the glass plate 2, until the lower circular plate 14 is above the NVP product, the lead screw 5 is rotated. When the lead screw 5 rotates, it can drive the rotatably connected trapezoidal block 8 to move down inside the elliptical cylinder 6. When the trapezoidal block 8 moves down, it can push the two extrusion plates 9 away from each other. When the extrusion plates 9 move away from each other, they press on the teeth on the vertical rod 4, thereby fixing the vertical rod 4 and also fixing the upper circular plate 12 and the lower circular plate 14. Since the lower circular plate 14 is above the NVP product, it can effectively limit the NVP product, so as to reduce the swing of the NVP product when moving the container 1, thereby achieving the stable storage of the NVP product.

[0027] Simultaneously, when the lead screw 5 rotates, it can move downward and push the piston plate 10 downward in the mounting cylinder 7, and squeeze the gas in the mounting cylinder 7 into the airbag 16 through the hose. Since the airbag 16 is located between the upper circular plate 12 and the lower circular plate 14, the airbag 16 expands as the gas increases. The expansion of the airbag 16 can squeeze and stretch the rubber ring 13 until the outer surface of the rubber ring 13 contacts the inner wall of the tank 1 and forms a squeeze, thereby achieving a better sealing effect on the NVP product in the tank 1.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "connection", "linking", "fixing", etc., should be interpreted broadly.

[0029] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
