Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of chemical raw material storage equipment, specifically a raw material storage box for processing foaming modifiers. Background Technology
[0002] A raw material storage box for foam modifier processing is a container device specifically designed to store various raw materials (such as polymer base materials, foaming agents, additives, etc.) required for the production of foam modifiers. Its design must take into account the characteristics of the raw materials (such as chemical stability, volatility, hygroscopicity, etc.), storage environment requirements, and production continuity requirements.
[0003] Some foaming modifiers (such as polyurethanes and polystyrene) are temperature-sensitive and may decompose, polymerize, or volatilize at high temperatures, releasing toxic gases. Others (such as polyether polyols) are hygroscopic, and high humidity environments may lead to hydrolysis or deterioration. To improve the storage performance and stability of foaming modifier raw materials, sealed storage boxes are typically used to isolate the raw materials from air, thereby enhancing the safety of the storage process.
[0004] Although the raw materials for foaming agents are stored in sealed storage boxes, there is still a risk of volatilization and decomposition. The main reason is that trace amounts of air or moisture may be introduced during the filling process into the sealed storage boxes. These gases, upon contact with the foaming agent raw materials, may continuously react to generate toxic or other volatile gases, causing the pressure inside the storage box to gradually increase, creating a safety hazard. Even with storage boxes designed to withstand high pressure, vibrations from road bumps during transportation can further exacerbate the expansion of gas inside the box, potentially leading to box deformation or even an explosion. Therefore, significant safety hazards exist in the storage and transportation of foaming modifiers. Utility Model Content
[0005] To address the shortcomings of existing technologies, this utility model provides a raw material storage box for processing foaming modifiers, thereby improving the safety of storing foaming modifiers in the storage box.
[0006] To achieve the above objectives, this utility model provides the following technical solution: a raw material storage box for processing foaming modifier, including a sealed box and a box cover. A negative pressure box is fixedly connected to the side of the box cover away from the sealed box. Several storage tanks are provided inside the sealed box. The top of each of the several storage tanks is connected to a spring tube, and the other end of each of the several spring tubes is connected to the negative pressure box.
[0007] Furthermore, an exhaust pipe is fixedly connected and connected to the side of the negative pressure box away from the box cover, and an exhaust valve is installed on the exhaust pipe.
[0008] Furthermore, a number of negative pressure connecting pipes are fixedly connected and connected to the side of the negative pressure box near the box cover. The other ends of the negative pressure connecting pipes all extend downward through the box cover and into the sealed box. The ends of the spring tubes away from the storage tank are respectively fitted with the ends of the negative pressure connecting pipes located inside the sealed box.
[0009] Furthermore, a connecting valve is fixedly connected to the end of the negative pressure connecting pipe away from the negative pressure box.
[0010] Furthermore, the inner wall of the top opening of the storage tank is provided with threaded grooves, and an external threaded ring is connected to the threaded grooves. The end of the external threaded ring away from the storage tank is fixedly connected to the tank cover, and the end of the tank cover away from the storage tank is connected to the spring tube.
[0011] Furthermore, a connector is fixedly connected to the side of the tank cover away from the storage tank, and the connector is connected to an external threaded ring.
[0012] Furthermore, a protective filter screen is connected to the inner wall of the external threaded ring.
[0013] Furthermore, a mesh frame is fixedly connected to the outer edge of the protective filter screen, and the outer wall of the mesh frame is threadedly connected to the inner wall of the external threaded ring.
[0014] Furthermore, a screw rod is fixedly connected to the inner wall of the wire mesh frame at the end away from the can lid.
[0015] Furthermore, two screw rings are fixedly connected to the side of the tank cover away from the storage tank, with the two screw rings located on both sides of the joint.

Detailed Implementation
[0027] 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.
[0028] Please see Figures 1 to 8 A raw material storage box for foaming modifier processing includes a sealed box 1 and a box cover 2. A negative pressure box 3 is fixedly connected to the side of the box cover 2 away from the sealed box 1. Several storage tanks 4 are provided inside the sealed box 1. The top of each of the several storage tanks 4 is connected to a spring tube 5. The other end of each of the several spring tubes 5 is connected to the negative pressure box 3.
[0029] like Figures 1 to 8 As shown, the main improvement of this utility model is to avoid the formation of high pressure inside the storage tank 4, thereby improving the safety of raw material storage. Figures 1 to 5As shown, in the present invention, the raw material storage box for processing foaming modifiers is used by placing the foaming modifier raw material into the storage tank 4 and connecting the storage tank 4 to the negative pressure box 3 using a spring tube 5. When the raw material in the storage tank 4 reacts with the residual air in the storage tank 4 to produce gas, this gas is drawn into the negative pressure box 3, thereby preventing the gas expansion from causing high pressure in the storage tank 4, thus improving the safety of storing the foaming modifier raw material in the storage tank 4. It should be noted that the negative pressure box 3 can be a corrugated folding box, utilizing the folding and rebounding performance to ensure that the negative pressure box 3 always maintains contact with the spring tube 5. The storage tank 4 creates a negative pressure suction effect, and as the gas in the negative pressure box 3 gradually increases, the volume of the negative pressure box 3 gradually increases. This allows for a direct understanding of the amount of gas generated through the volume of the negative pressure box 3, enabling timely treatment of harmful gases within the negative pressure box 3. Furthermore, the use of the spring tube 5 allows it to be extended when the box cover 2 is open, thus maintaining the connection between the storage tank 4 and the negative pressure box 3. When the box cover 2 is placed inside the sealed box 1, the spring tube 5 can retract smoothly, preventing multiple spring tubes 5 from becoming entangled and maintaining the gas flow performance of the spring tube 5.
[0030] like Figure 1 and Figure 2 As shown, an exhaust pipe 6 is fixedly connected and connected to the side of the negative pressure box 3 away from the cover 2, and an exhaust valve 7 is installed on the exhaust pipe 6. When a large amount of gas is extracted from the negative pressure box 3, the gas in the negative pressure box 3 can be discharged and rendered harmless through the exhaust valve 7 and the exhaust pipe 6. After the gas in the negative pressure box 3 is treated, the corrugated negative pressure box 3 is flattened and the exhaust valve 7 is closed again, thereby restoring the negative pressure effect of the negative pressure box 3.
[0031] like Figures 1 to 4 As shown, a number of negative pressure connecting pipes 8 are fixedly connected and connected to the side of the negative pressure box 3 near the box cover 2. The other ends of the negative pressure connecting pipes 8 all extend downward through the box cover 2 and into the sealed box 1. The ends of the spring tubes 5 away from the storage tanks 4 are respectively fitted with the ends of the negative pressure connecting pipes 8 located inside the sealed box 1. The negative pressure connecting pipes 8 at the bottom of the negative pressure box 3 can be easily connected to the spring tubes 5, so that each storage tank 4 can be connected to the negative pressure box 3 independently. This can prevent the cross-flow of harmful gases generated in multiple storage tanks 4, thereby preventing these gases from reacting with the raw materials inside other storage tanks 4 and improving the stability of the raw materials stored in the storage tanks 4.
[0032] like Figures 1 to 4As shown, a connecting valve 9 is fixedly connected to the end of the negative pressure connecting pipe 8 away from the negative pressure box 3. With the connecting valve 9 installed at the end of the negative pressure connecting pipe 8, when some of the storage tanks 4 inside the sealed box 1 are not in use, the connecting valve 9 can be closed to seal the negative pressure connecting pipe 8, thereby preventing gas inside the negative pressure box 3 from overflowing from the negative pressure connecting pipe 8. Other negative pressure connecting pipes 8 connected to spring tubes 5 can have their connecting valves 9 opened, allowing gas from the storage tanks 4 to smoothly enter the negative pressure box 3.
[0033] like Figures 1 to 8 As shown, the inner wall of the top opening of the storage tank 4 is provided with a threaded groove 401. An external threaded ring 10 is connected to the internal thread of the threaded groove 401. The end of the external threaded ring 10 away from the storage tank 4 is fixedly connected to a tank cover 11. The end of the tank cover 11 away from the storage tank 4 is connected to a spring tube 5. The connection between the external threaded ring 10 and the threaded groove 401 of the storage tank 4 can improve the sealing effect after the tank cover 11 is connected to the storage tank 4, ensuring that the gas inside the storage tank 4 can enter the spring tube 5 through the inner hole of the external threaded ring 10 and the perforation of the tank cover 11, and then be discharged into the negative pressure box 3.
[0034] like Figures 1 to 8 As shown, a connector 12 is fixedly connected to and communicates with the side of the tank lid 11 away from the storage tank 4, and the connector 12 communicates with the external threaded ring 10. The connector 12 facilitates the connection and fixation of the spring tube 5 to the tank lid 11.
[0035] like Figures 6 to 8 As shown, a protective filter 13 is connected to the inner wall of the external threaded ring 10. Installing the protective filter 13 on the inner side of the external threaded ring 10 can prevent the raw materials stored inside the storage tank 4 from entering the spring tube 5 and causing pipe blockage, thereby improving the smoothness of the process of harmful gases being discharged into the negative pressure box 3.
[0036] like Figure 7 and Figure 8 As shown, a mesh frame 14 is fixedly connected to the outer edge of the protective filter 13, and the outer wall of the mesh frame 14 is threadedly connected to the inner wall of the external threaded ring 10. The threaded connection between the mesh frame 14 and the inner side of the external threaded ring 10 facilitates the replacement and installation of the protective filter 13.
[0037] like Figure 7 and Figure 8 As shown, a screw rod 15 is fixedly connected to the inner wall of the end of the mesh frame 14 away from the can lid 11. The screw rod 15 facilitates the screwing of the mesh frame 14 inside the external threaded ring 10.
[0038] like Figures 1 to 8As shown, two screw rings 16 are fixedly connected to the side of the can lid 11 away from the storage tank 4. The two screw rings 16 are located on both sides of the connector 12. The two screw rings 16 can be used to easily tighten the can lid 11 and the external threaded ring 10 to the top of the storage tank 4. At the same time, by hooking the fingers inside the screw rings 16, the storage tank 4 can be easily screwed up, so that the storage tank 4 can be placed into or taken out of the sealed box 1.
[0039] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention.
