Description

Technical Field

[0001] This utility model relates to the field of insulated boxes, and in particular to an insulated box and its processing equipment. Background Technology

[0002] An insulated box is a container specifically designed for storing and transporting goods. Its unique structure and material selection ensure that goods can remain at low temperatures for extended periods.

[0003] Traditional insulated boxes often use a single insulation material, such as ordinary foam plastic, which has relatively high thermal conductivity and cannot effectively block external heat from entering. During long-term transportation or in high-temperature environments, the internal temperature fluctuates greatly, making it difficult to meet the stringent requirements of temperature-sensitive items. For example, when transporting fresh food in the high temperatures of summer, ordinary insulated boxes cannot maintain a low temperature for extended periods, causing the food to spoil easily; when transporting biological products such as vaccines, temperature fluctuations may affect their activity and reduce product quality.

[0004] When dry ice is used to provide a low temperature for insulated boxes, the carbon dioxide gas produced by the sublimation of dry ice accumulates inside the box, causing a rapid increase in pressure. This not only threatens the sealing structure of the insulated box, potentially leading to seal failure and allowing hot outside air to enter and disrupt the low-temperature environment, but also poses safety hazards, such as causing the insulated box to rupture, endangering personnel safety and the integrity of the goods. In cold chain transportation practice, cargo losses due to pressure issues occur frequently, increasing operating costs and risks. Utility Model Content

[0009] Furthermore, casters are installed at the bottom of the box; A limiting groove is provided above the lid; One end of the flow channel is connected to the limiting sink, and the other end of the flow channel is located on the outer peripheral side wall of the box cover; the flow channel is used to drain the water from the limiting sink; the flow channel is a through hole.

[0010] Furthermore, a snap-on opening is provided on the outer wall of the box shell, and a snap handle is located inside the box shell and is fixedly connected to the box shell; the snap handle forms a snap-on recess, which communicates with the snap-on opening, and the snap-on recess is used by the user / carrier to move the box by hand in a snap-on manner.

[0011] Furthermore, it also includes a remaining volume space measurement system, comprising a distance sensor, an analog-to-digital converter, a microcontroller unit, and a display module; The microcontroller unit is electrically connected in sequence to the analog-to-digital converter and the distance sensor; the microcontroller unit is also electrically connected to the display module; the remaining volume space measurement system also includes a battery to provide power.

[0012] On the other hand, the processing equipment for the insulated box is characterized by including a support, a rotating power source, a rotating platform, a vibration unit, and a filling device; A scaffold is used to create a workspace; The filling device is used to fill aerogel particles; the filling head of the filling device is fixed to the support; the filling head is used to fill aerogel particles into the aerogel tank of the box. The rotating platform is located within the workspace, and the housing is used to place the rotating platform.

[0016] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows: Enhanced thermal insulation performance: Aerogel particles in the insulation layer are combined with the vacuum insulation board. The extremely low thermal conductivity of the aerogel works synergistically with the vacuum insulation effect of the vacuum insulation board to significantly reduce heat conduction.

[0022] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. Identical components are indicated by the same reference numerals.

[0023] It should be noted that the terms “front,” “back,” “left,” “right,” “up,” and “down” used in the following description refer to the directions shown in the attached diagram, while the terms “inside” and “outside” refer to the directions toward or away from the geometric center of a specific component, respectively.

[0024] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Example

[0025] As shown in the attached diagram, the insulated box includes a box body 20 and a box lid 10. The housing 20 is composed of an inner shell and an outer shell, and an insulation layer is disposed between the inner shell and the outer shell, that is, the inner shell and the outer shell of the housing 20 wrap the insulation layer.

[0026] The shell of the cover 10 is wrapped around the outside of the insulation layer.

[0027] The insulation layers of both the lid 10 and the body 20 are equipped with independent interlayers—aerogel grooves and vacuum plate grooves—with the aerogel grooves overlapping each other. The aerogel grooves are filled with aerogel particles, and the vacuum plate grooves are filled with vacuum insulation panels. The aerogel particles and vacuum insulation panels filling the interlayers are used to improve the thermal insulation performance of the insulated box. In summary, the insulation layer incorporates a sandwich structure consisting of aerogel particles and a vacuum insulation panel. The aerogel material, with its extremely low thermal conductivity, is one of the best-performing solid materials known to date, effectively blocking heat conduction. The vacuum insulation panel, through vacuuming, reduces gas convection and conduction. The combination of these two elements significantly enhances the overall insulation performance of the insulated box, maintaining a stable internal temperature for extended periods and meeting the storage and transportation needs of temperature-sensitive items.

[0028] Furthermore, when dry ice is placed inside an insulated box for cryogenic storage or transportation, the dry ice continuously sublimates into carbon dioxide gas. If this gas accumulates rapidly in a confined space, it can cause a rapid increase in pressure inside the box, posing a safety hazard and potentially affecting the box's sealing performance. Aerogel's unique porous structure acts like a fine "gas trapping net," effectively adsorbing the carbon dioxide produced by dry ice sublimation. As the dry ice continues to sublimate, carbon dioxide molecules diffuse into the countless tiny pores of the aerogel, where they are temporarily stored. This significantly slows down the rate of pressure buildup inside the insulated box, maintaining the pressure within a safe and stable range for a longer period.

[0029] In addition, the filler in the aerogel groove can be replaced with a vacuum insulation panel, allowing for more flexible adaptation to customer needs.

[0030] Furthermore, the surface of the insulation layer near the inside of the insulated box is coated with a nano-aerogel coating, forming an ultra-thin, high-barrier layer. This nano-aerogel coating isolates the box from moisture and corrosive gases, extending the lifespan of the inner shell; it also prevents cold air leakage through the foam micropores, further reducing the dry ice evaporation rate.

[0031] Furthermore, the vacuum insulation panel is closer to the interior of the box than the aerogel particle interlayer; The insulation layer is located between the vacuum insulation board and the aerogel particles to form the first material board; The insulation layer is located on the side of the aerogel particle interlayer away from the inside of the box, forming a second material plate; The first material plate and the second material plate have reflective films on both sides, which can achieve bidirectional heat blocking and form a foam layer between adjacent reflective films to reduce heat convection.

[0032] Furthermore, a support hinge 50 is installed on one side of the box body 20 and the box cover 10; the support hinge 50 (available on the market) restricts the box cover 10 from opening to a certain angle.

[0033] A support storage groove 122 is provided at the contact interface between the lid 10 and the body 20 when they are closed; one end of the support 60 is rotatably connected to the inner wall of the support storage groove 122.

[0034] A support groove 212 is provided at the contact position between the box body 20 and the box cover 10 when they are closed.

[0035] When the box body 20 and the box cover 10 are closed, the support member 60 can be stored in the support member storage groove 122; when the box cover 10 is opened, the other end of the support member 60 can rotate and fall into the support member groove 212.

[0036] When the box body 20 and the lid 10 are closed, the support member 60 is completely located in the support member storage groove 122; when the lid 10 is opened, the other end of the support member 60 can rotate and fall into the support member groove 212; thus, the support member 60 provides a certain support for the open lid 10, improving the stability of the lid in the open state.

[0037] Furthermore, the cover 10 has a pressure relief channel. When the cover 10 is placed on the box body 20, the pressure relief channel is connected to the interior of the box body 20. A pressure relief valve is installed in the pressure relief channel. The pressure relief valve is detachably connected to the cover 10. The outer wall of the pressure relief valve and the cover 10 are both provided with mounting holes. The pressure relief valve is installed on the cover 10 by bolts passing through the mounting holes of the outer wall of the pressure relief valve and the cover 10.

[0038] Furthermore, casters 30 are installed at the bottom of the housing 20; A limiting groove 121 is provided above the box cover 10; When multiple layers of insulated boxes are stacked, the rollers 30 of the upper insulated box are located within the limiting groove 121, thus ensuring that the stacking is in a stable state.

[0039] Furthermore, one end of the flow channel 1211 is connected to the inner part of the limiting sink 121, and the other end of the flow channel 1211 is located on the outer peripheral side wall of the box cover 10; the flow channel 1211 is used to drain the water from the limiting sink 121; the flow channel 1211 is a through hole.

[0040] Furthermore, a latching opening is provided on the outer wall of the housing 21, and a latch 211 is located inside the housing 21 and is fixedly connected to the housing 21. The latch 211 forms a latching recess, which communicates with the latching opening. The latching recess is used by the user / carrier to move the device by hand in a latching manner.

[0041] Furthermore, it also includes a remaining volume space measurement system, comprising a distance sensor, an analog-to-digital converter, a microcontroller unit, and a display module; The microcontroller unit is electrically connected in sequence to the analog-to-digital converter and the distance sensor; the microcontroller unit is also electrically connected to the display module; the remaining volume space measurement system also includes a battery to provide power.

[0042] The microcontroller unit, distance sensor, analog-to-digital converter, and battery are located inside the lid 10 itself. The detection end of the distance sensor emits a signal to the bottom of the insulated box. The distance sensor is used to detect the depth of the remaining space inside the insulated box. The display module is located on the outer surface of the lid 10. The display module is used to display the detection result of the distance sensor. Example

[0043] The processing equipment 200 for the insulated box includes a support 201, a rotary power source 202, a rotary platform 203, a vibration unit 204, and a filling device 205; Frame 201 constructs a workspace; The filling device 205 is used to fill aerogel particles; the filling head 2051 of the filling device 205 is fixed to the bracket 201; the filling head is used to fill aerogel particles into the aerogel tank of the housing 20.

[0044] The rotating platform 203 is located within the workspace, and the housing 20 is used to place the rotating platform 203. The rotary power source 202 is used to drive the rotary platform 203 to rotate.

[0045] The rotating platform 203 rotates the box 20 at intervals of 90 degrees, and then the aerogel grooves on the four side walls of the box 20 pass under the aerogel grooves in sequence, and the filling head fills the aerogel particles.

[0046] Furthermore, the pressure structure 206 is used to press down and fix the filling device 205, thereby facilitating filling; the pressure structure 206 consists of an electric cylinder and a pressure plate, the outer wall of the electric cylinder is fixedly connected to the bracket 201; the extension end of the electric cylinder is fixedly provided with a pressure plate, and the pressure plate is provided with a rubber layer to press the side of the heat preservation box to prevent rigid collision damage to the heat preservation box.

[0047] Furthermore, the rotating platform 203 consists of a rotating plate 2031, a shock-absorbing spring 2032, a guide rod 2033, and a support plate 2034; The rotating plate 2031 and the support plate 2034 are arranged in parallel, and a plurality of shock-absorbing springs 2032 are located between the rotating plate 2031 and the support plate 2034; the support plate 2034 is used to directly support the heat preservation box.

[0048] The rotating power source 202 is a servo motor. The housing of the servo motor is fixed to the bracket 201, and the rotating shaft of the servo motor passes through the rotating platform 203 and is fixedly connected to the rotating plate 2031. The lower ends of the plurality of guide rods 2033 are fixedly connected to the rotating plate 2031, and the guide rods 2033 slide through the support plate 2034.

[0049] Furthermore, the vibration unit 204 is fixed below the support plate 2034, and the function of the vibration unit 204 is to ensure that the aerogel particles filled in the insulation box are compacted.

[0050] In summary, it also has the following advantages: (i) The double aerogel particle layer (economic type) has significant advantages in lightweighting and cost control: its density is only 40kg / m³, the empty box weight is ≤15kg, which can significantly reduce logistics energy consumption by 30% and reduce costs by 40% compared with the VIP solution; at the same time, it has adaptive temperature change characteristics, and the aerogel particles can automatically fill the gaps during thermal expansion and contraction, effectively avoiding the problem of low-temperature embrittlement.

[0051] (ii) In comparison, the double vacuum insulation panel (high performance type) focuses on ultimate performance: its core advantage lies in its excellent heat preservation ability, with a thermal conductivity as low as 0.005 W / (m·k) and a dry ice evaporation rate of ≤1.2% / day, which extends the heat preservation time by 50%; and it has aerospace-grade reliability. Because it does not contain phase change material (PCM), it can avoid the risk of low temperature failure below -80°C. At the same time, its compressive strength is ≥200kPa, which can ensure that it can withstand high-strength stacking and transportation.

[0052] (iii) In addition, the dual aerogel configuration has greater advantages in terms of environmental protection and economy: it meets the EU CBAM carbon tariff exemption standard and can reduce carbon emissions by 30%; at the same time, thanks to this green technology feature, customers can reduce procurement costs by up to 20% after applying for relevant subsidies.
