Description

Technical Field

[0001] This utility model relates to the field of foam board raw material storage technology, specifically an EPS foam board production raw material storage mechanism. Background Technology

[0002] Polystyrene beads are expandable, lightweight polymers containing foaming agents (such as pentane), primarily used as raw materials for EPS foam boards in packaging, building insulation, and other fields. EPS beads should generally be stored at no more than 20°C and can be kept for six months to one year, but the storage time is best controlled within three months. Storage in containers should not exceed two months, and storage in metal containers should not exceed six months. Excessive temperature may cause the foaming agent within the beads to volatilize, affecting subsequent foaming performance.

[0003] In existing technologies, EPS beads are typically stored in barrel-shaped containers and then placed in a cool, ventilated place. However, some locations may lack a suitable storage environment, and the temperature of the stored EPS beads may rise due to increased ambient temperature, causing the foaming agent inside to evaporate and affecting their performance. In other words, the storage container itself does not have measures to cope with temperature changes, and the quality of the storage environment is highly demanding. At the same time, since EPS beads are flammable, relatively complete fire prevention measures are also required. However, the flame-retardant and heat-insulating properties of the barrel-shaped container itself are limited, so it cannot provide effective isolation in the event of a fire. Therefore, to address the above problems, a storage mechanism for EPS foam board production raw materials is proposed. Utility Model Content

[0004] To address the technical problems of existing foam board raw material storage mechanisms lacking efficient measures to cope with temperature changes, having high requirements for the quality of the storage environment, and having limited flame-retardant and heat-insulating properties, making it difficult to provide effective isolation in the event of a fire, this utility model provides an EPS foam board production raw material storage mechanism.

[0005] The technical solution adopted by the embodiments of this application to solve its technical problem is:

[0006] An EPS foam board production raw material storage mechanism includes an outer shell with an inner liner installed inside, and a central convex cylinder formed in the middle of the inner liner; a lid that covers the top of the inner liner and is sealed to it; a water inlet pipe that is sealed to the top of the central convex cylinder and extends out of the lid; and a temperature detection frame that is installed on the lower end face of the lid and arranged in a circumferential array. An outer heat-conducting cavity is formed between the outer shell and the inner liner, and an inner heat-conducting cavity communicating with the outer heat-conducting cavity is formed by the central convex cylinder. Cooling water is filled into both the outer and inner heat-conducting cavities.

[0007] In one possible implementation, water outlets are provided on both sides of the top of the outer barrel shell, and a drain outlet is provided at the bottom of the outer barrel shell, on which a solenoid valve is installed.

[0008] In one possible implementation, the inner wall of the outer shell is fixedly provided with a plurality of first heat-conducting fins arranged in a circumferential array, the outer wall of the inner liner is fixedly provided with a plurality of second heat-conducting fins arranged in a circumferential array, and the central convex cylinder is fixedly provided with a plurality of third heat-conducting fins arranged in a circumferential array, wherein the first heat-conducting fins and the second heat-conducting fins are arranged alternately.

[0009] In one possible implementation, a plurality of externally threaded shafts arranged in a circumferential array are fixedly provided on the top of the inner liner layer, and the barrel cover is provided with through holes corresponding to the externally threaded shafts, and the externally threaded shafts are equipped with locking nuts that are threadedly connected to them.

[0010] In one possible implementation, a thin film bag is provided inside the inner liner layer, which is attached to the inner wall of the inner liner layer. The raw materials are stored in the thin film bag. A through hole is provided at the top edge of the thin film bag, and the top of the thin film bag is sleeved on the external threaded shaft through the through hole.

[0011] In one possible implementation, the temperature detection frame includes a base, the lower end of which is fixedly connected to a cylindrical shell via a connecting rod. Several temperature sensing probes are embedded in the cylindrical shell, and a conical head is installed at the bottom end of the cylindrical shell.

[0012] In one possible implementation, a sealing element is installed in the middle of the bucket lid, which is sealed to the water injection pipe. The sealing element includes a sealing cylinder, the bottom of which is sealed to the bucket lid by a retaining ring, and the inner wall of the sealing cylinder is provided with several sealing rings that fit against the outer wall of the water injection pipe.

[0013] In one possible implementation, the sealing ring is a rubber ring with a cross-section that is serrated upwards.

[0014] In summary, this utility model has the following beneficial technical effects:

[0015] An outer heat-conducting cavity is formed between the outer shell and the inner liner, and an inner heat-conducting cavity is formed by the middle convex cylinder. Both the outer and inner heat-conducting cavities are filled with cooling water, which forms a protective insulating layer that can significantly reduce the impact of external temperature changes on the storage temperature inside the barrel. In extreme environments, the flow of cooling water can also remove heat to maintain the storage temperature inside the inner liner within a suitable range. As a complement, a temperature detection rack can detect the temperature of the inner liner to control the flow rate and temperature of the cooling water.

[0016] In addition, the water-based isolation layer formed in the above technical solution can play a certain role in flame retardancy and heat insulation. When an EPS bead in one of the storage units spontaneously combusts, its corresponding water isolation layer can prevent the combustion from spreading further. At the same time, the water isolation layer in the adjacent storage unit can significantly reduce the impact of the high temperature of combustion on the EPS beads stored inside, thereby significantly improving the safety during the storage process.

Detailed Implementation

[0024] The technical solution in this application embodiment is to solve the problems mentioned in the background art, and the overall idea is as follows:

[0025] like Figure 1 - Figure 2 As shown, this embodiment provides an EPS foam board production raw material storage mechanism, including an outer barrel shell 1, an inner liner layer 2 installed inside the outer barrel shell 1, a central convex cylinder 21 formed in the middle of the inner liner layer 2; and a barrel lid 5, which covers the top of the inner liner layer 2 and is sealed to the inner liner layer 2.

[0026] The above technical solution can form a storage space through the inner liner layer 2, while the lid 5 is used to seal the storage space to ensure its storage effect.

[0027] Among them, such as Figure 2 - Figure 3 As shown, an outer heat-conducting cavity 31 is formed between the outer shell 1 and the inner liner 2, and an inner heat-conducting cavity 32, which communicates with the outer heat-conducting cavity 31, is formed by the central convex cylinder 21. Cooling water is filled into both the outer heat-conducting cavity 31 and the inner heat-conducting cavity 32. The cooling water forms a protective isolation layer, which can significantly reduce the impact of external environmental temperature changes on the storage temperature inside the barrel. In extreme environments, the flow of cooling water can also remove heat to maintain the storage temperature inside the inner liner 2 within a suitable range. In addition, the water-based isolation layer formed in the above technical solution can play a certain role in flame retardancy and heat insulation. When an EPS bead in one of the storage units spontaneously combusts, its corresponding water isolation layer can prevent the combustion from spreading further. At the same time, the water isolation layer in the adjacent storage unit can significantly reduce the impact of the high temperature of combustion on the EPS beads stored inside, thereby significantly improving the safety during storage.

[0028] To achieve the circulating flow of cooling water, such as Figure 2 As shown, the EPS foam board production raw material storage mechanism provided in this embodiment also includes a water injection pipe 4, which is sealed on the top of the central convex cylinder 21 and extends out of the barrel cover 5. At the same time, water outlets 11 are provided on both sides of the top of the outer barrel shell 1, and a drain outlet 12 is provided at the bottom of the outer barrel shell 1. A solenoid valve is installed on the drain outlet 12. When cooling water circulation is required, cooling water is added from the water injection pipe 4. At the same time, under the action of water pressure, the drain outlet 11 will discharge the cooling water added in the previous batch. Since the temperature of the newly added cooling water is low, it will flow downwards and squeeze out the cooling water added in the previous batch, ensuring the cooling water circulation effect. When the entire storage mechanism is not used or does not need to use cooling water for a short period of time, all the cooling water is completely discharged through the drain outlet 12.

[0029] like Figure 5 As shown, a sealing element 7 is installed in the middle of the bucket lid 5, which is sealed to the water injection pipe 4. The sealing element 7 includes a sealing cylinder 71, the bottom of which is sealed to the bucket lid 5 through a retaining ring 72. The inner wall of the sealing cylinder 71 is provided with several sealing rings 73 that fit against the outer wall of the water injection pipe 4. In particular, the sealing rings 73 are rubber rings with a toothed cross-section that is obliquely upward. The above structure can realize the detachable connection between the water injection pipe 4 and the bucket lid 5, and can ensure the sealing of the connection through the sealing element 7. Based on the toothed cross-sectional feature of the sealing rings 73, the resistance applied by the sealing rings 73 due to friction can be significantly reduced when the bucket lid 5 is fitted onto the water injection pipe 4 and moves downward, which can facilitate the smooth installation of the bucket lid 5.

[0030] To improve heat dissipation, such as Figure 2 - Figure 3 As shown, the inner wall of the outer shell 1 is fixedly provided with a plurality of first heat-conducting fins 13 arranged in a circumferential array, the outer wall of the inner liner 2 is fixedly provided with a plurality of second heat-conducting fins 24 arranged in a circumferential array, and the central convex cylinder 21 is fixedly provided with a plurality of third heat-conducting fins 25 arranged in a circumferential array. The first heat-conducting fins 13 and the second heat-conducting fins 24 are arranged alternately. The above three types of fins can expand the contact area with cooling water, thereby improving the heat exchange efficiency to a certain extent and improving the heat dissipation efficiency of the storage space in the inner liner 2.

[0031] To detect the temperature of the inner tank layer 2, and to control information such as the flow rate and temperature of the cooling water, such as... Figure 2 - Figure 4 As shown, the EPS foam board production raw material storage mechanism provided in this embodiment also includes a temperature detection frame 6, which is installed on the lower end face of the bucket lid 5 and arranged in a circumferential array. The temperature detection frame 6 includes a base 61, and a cylindrical shell 63 is fixedly connected to its lower end face through a connecting rod 62. Several temperature sensors 64 are embedded in the cylindrical shell 63, and a conical head 65 is installed at the bottom of the cylindrical shell 63. Based on the above scheme, the temperature sensors 64 can monitor the storage environment temperature and provide necessary reference information for the adjustment of cooling water. In addition, the conical head 65 can ensure that the temperature detection frame 6 can be smoothly inserted into the stacked EPS beads when the bucket lid 5 is installed.

[0032] like Figure 1 , Figure 3 As shown, a number of external threaded shafts 22 arranged in a circumferential array are fixedly provided on the top of the inner liner layer 2. The lid 5 is provided with through holes corresponding to the external threaded shafts 22, and the external threaded shafts 22 are equipped with locking nuts 23 that are threadedly connected to them. The above structure can provide the necessary structural foundation for the fixed installation of the lid 5. The lid 5 and the inner liner layer 2 are fixedly connected by locking nuts 23.

[0033] In addition, a thin film bag 26 is provided inside the inner liner layer 2, which is attached to the inner wall of the inner liner layer 2. The raw materials are stored in the thin film bag 26. The top edge of the thin film bag 26 has a through hole, and the top of the thin film bag 26 is sleeved on the external threaded shaft 22 through the through hole. The thin film bag 26 can isolate the stored EPS beads, ensuring their storage effect, and can also facilitate the removal of the stored EPS beads. That is, you only need to pull out the thin film bag 26 to take out all the EPS beads stored inside.

[0034] The working principle and usage process of this utility model:

[0035] Both the outer heat conduction cavity 31 and the inner heat conduction cavity 32 are filled with cooling water. The cooling water forms a protective isolation layer, which can significantly reduce the impact of external environmental temperature changes on the storage temperature inside the barrel. In extreme environments, the flow of cooling water can also remove heat to maintain the storage temperature inside the inner liner 2 within a suitable range.

[0036] When cooling water circulation is required, cooling water is added through the water inlet pipe 4. At the same time, under the action of water pressure, the outlet 11 will discharge the cooling water added in the previous batch. Since the temperature of the newly added cooling water is low, it will flow downwards and squeeze out the cooling water added in the previous batch, ensuring the cooling water circulation effect. When the entire storage unit is not used or does not need to use cooling water for a short period of time, all the cooling water is completely discharged through the drain outlet 12.

[0037] As a complement, the temperature detection rack 6 can detect the temperature of the inner tank layer 2, which is used to control the flow rate and temperature of the cooling water. Among them, several temperature sensors 64 play the role of monitoring the temperature of the storage environment, providing necessary reference information for the adjustment of the cooling water.

[0038] Finally, it should be noted that the above embodiments are merely examples for clearly illustrating the present invention and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
