Description

Technical Field

[0001] This utility model relates to the field of constant temperature box technology, and in particular to a constant temperature box for storing sponge raw materials to prevent crystallization. Background Technology

[0002] Sponge raw materials are mostly high-molecular materials such as polyurethane prepolymers that are easily affected by temperature. During storage, if the ambient temperature is too low, the material molecules will become regularized and crystallize, resulting in increased viscosity and decreased fluidity of the raw materials. This makes it difficult to mix them evenly during subsequent processing, affecting the cell structure, density and mechanical properties of sponge products. Therefore, it is necessary to design a constant temperature box for storing sponge raw materials to prevent crystallization.

[0003] Currently, existing sponge raw material storage devices are prone to problems because the internal temperature cannot be effectively maintained in a suitable range during storage. This can cause the raw materials to crystallize due to low temperatures, resulting in crystal deposition, which reduces the preservation effect of the raw materials and affects the quality of the raw materials in later use. At the same time, when maintaining the temperature of the raw materials, the lack of sufficient heat preservation measures may lead to rapid heat loss, increasing energy consumption and reducing the efficiency of the storage unit. Utility Model Content

At the same time, the lack of sufficient heat preservation measures leads to rapid temperature loss, which increases energy consumption and reduces the storage efficiency of the box.

[0014] (III) Beneficial Effects

[0015] This utility model provides a constant temperature box for storing sponge raw materials to prevent crystallization, which has the following beneficial effects:

[0016] 1. This anti-crystallization constant temperature box for storing sponge raw materials utilizes a hot air mechanism. When the device is to be used for storage, the PTC ceramic heater and hot air fan are activated to generate heat. Hot air is then transferred from the heat transfer port to the air box. The hot air is blown into all corners of the box through the air blowing windows and hot air vents on the bottom of the air box. The internal air is then transported by the air duct and drawn into the return air box inside the air box. From there, the air is transported back to the hot air box for heating through the return air duct at the top of the return air box. Hot air is continuously blown out. At the same time, a stirring rack is installed inside the box to ensure that the raw materials inside can be evenly contacted with the air due to stirring, promoting uniform heating. This allows hot air to be continuously blown into the interior from the four corners on the top, maintaining a suitable internal temperature threshold, improving the preservation effect of the sponge raw materials, and preventing crystallization and deposition of the raw materials due to a drop in internal temperature, which would affect the later use of the raw materials.

[0017] 2. This anti-crystallization constant temperature box for storing sponge raw materials, through the setting of the insulation mechanism, has an outer protective shell installed on the outside of the box when the device is heating up for storage. Polyurethane foam board is installed inside the outer protective shell, which provides the initial layer of external insulation. Then, rubber and plastic insulation cotton is also installed inside the polyurethane foam board, providing multi-layer insulation. However, in order to prevent the internal raw materials from damaging the insulation material, an inner protective layer for isolation and corrosion prevention is installed inside the rubber and plastic insulation cotton, thereby increasing the original insulation effect of the box and improving the storage effect and quality of the device.
