Description

Technical Field

[0001] The utility model relates to the technical field of storage cabinets, in particular to a multi-layer partitioned temperature-controlled asphalt test piece storage cabinet. Background Art

[0002] Asphalt specimens are key samples for evaluating and studying asphalt material properties. Proper storage conditions are crucial for ensuring the accuracy of subsequent experimental data and the effectiveness of engineering applications. However, common asphalt specimen storage devices currently available on the market have significant shortcomings in temperature control, particularly in their ability to differentiate temperature management for asphalt specimens of varying types and characteristics.

[0003] Traditional storage cabinets typically feature a single heating source or a simple zoned heating system, making precise temperature regulation difficult. For example, when storing asphalt specimens of multiple grades or types simultaneously, a single temperature setting cannot optimally meet the storage requirements of all specimens, due to the varying temperature sensitivities and optimal storage temperature ranges of each grade. This can lead to performance changes in some specimens due to improper storage temperature, compromising the accuracy of experimental results and the effectiveness of engineering applications. Utility Model Content

[0004] In order to overcome the above-mentioned shortcomings, the utility model provides a multi-layer partitioned temperature-controlled asphalt specimen storage cabinet.

[0005] The technical implementation scheme of the utility model is as follows: a multi-layer partitioned temperature-controlled asphalt specimen storage cabinet, including a storage cabinet, a control panel, a storage box, an air intake pipe, a heating pipe, a diversion frame, an air intake fan and a return pipe. The control panel is installed on the front side of the lower part of the storage cabinet. The upper part of the storage cabinet is arranged in sequence from top to bottom and is provided with four slides at intervals. Each slide is connected to a storage box in a pull-out manner. The rear side of the storage cabinet is connected to the diversion frame. The front side of the diversion frame is connected to an air intake pipe at a position aligned with each slide. The air intake pipe is connected to the diversion frame. They are interconnected, and a slot that matches the shape of the air intake pipe is opened on the rear side of each storage box. The storage box is connected to the air intake pipe through this slot. Heating pipes are installed in the air intake pipes. The four heating pipes have decreasing lengths from top to bottom. Intake fans are symmetrically installed on the rear side of the diverter frame. Return pipes are connected to the left and right sides of the storage box in the storage cabinet. The front end of the return pipe is connected to the inside of the storage cabinet but not connected, and the rear end of the return pipe is connected to the diverter frame. The heating pipe and the air intake fan are electrically connected to the control board.

[0006] As a further preferred solution, a sealing ring is provided at the portion where the front end of the storage box contacts the slide groove.

[0007] As a further preferred solution, it also includes a lifting baffle and a guide rod. Guide rods are connected to both sides of the bottom of the air intake pipe. A lifting baffle is slidably connected between each corresponding two guide rods, and the lifting baffle cooperates with the front port of the air intake pipe.

[0008] As a further preferred solution, it also includes a tension spring and a V-shaped plate. The tension spring is sleeved on the guide rod. The upper and lower ends of the tension spring are respectively connected to the lifting baffle and the air intake pipe. A through hole is opened at the lower end of the lifting baffle. A V-shaped plate is connected to the rear side of each storage box, and the V-shaped plate passes through the corresponding through hole.

[0009] As a further preferred solution, a notch is provided at the bottom of the V-shaped plate, and the notch is engaged with the lifting baffle.

[0010] As a further preferred solution, a partition bar is also included, and two partition bars are spaced apart and connected at the bottom of each storage box.

[0011] The beneficial effects are: 1. By setting S-shaped heating tubes with lengths gradually shortening from top to bottom, the heat generated by each heating tube is different, and the temperature of the heated air also decreases accordingly, thereby achieving precise temperature control of the areas where different storage boxes are located, meeting the requirements for temperature stability when storing asphalt samples, and ensuring that the performance of the asphalt samples during storage is not affected by temperature.

[0012] 2. The arrangement of the lifting baffle, guide rod, tension spring and V-shaped plate. When the storage box is pulled forward, the V-shaped plate drives the lifting baffle to rise and close the front port of the air intake pipe to prevent hot air from spraying out and causing harm to the staff; when the storage box is pushed back, the V-shaped plate can make the lifting baffle fall and open, restoring the normal hot air supply, ensuring the safety of the operator without affecting the normal use of the device.

For example, "connect" may refer to a fixed connection, a detachable connection, or an integral connection; it may refer to a mechanical connection or an electrical connection; it may refer to a direct connection or an indirect connection through an intermediate medium; or it may refer to internal communication between two components. A person skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0023] Embodiment: A multi-layer partitioned temperature-controlled asphalt specimen storage cabinet, such as Figure 1-Figure 5As shown, it includes a storage cabinet 1, a control panel 101, a storage box 2, a partition bar 3, an air intake pipe 4, a heating pipe 5, a diversion frame 6, an air intake fan 7 and a return pipe 8. The control panel 101 is installed on the front side of the lower part of the storage cabinet 1 by bolts for controlling and adjusting the operation of the entire device. The upper part of the storage cabinet 1 is arranged in sequence from top to bottom and is provided with four slides at intervals. A storage box 2 is connected to each slide in a pull-out manner. The storage box 2 is specially used for storing asphalt samples. Two partition bars 3 are connected to the bottom of each storage box 2 at intervals to separate the asphalt test pieces stored in the storage box 2 and make the storage more regular. A sealing ring is provided at the part of the front end of the storage box 2 that contacts the slide, which can improve the sealing between the storage box 2 and the slide to prevent the stored asphalt from getting damp or the internal temperature from being discharged outward. The rear side of the storage cabinet 1 is connected to The diversion frame 6 has an air intake pipe 4 connected to the front side of the diversion frame 6 at a position aligned with each slide slot. The air intake pipe 4 and the diversion frame 6 are connected to each other. A slot matching the shape of the air intake pipe 4 is provided on the rear side of each storage box 2. The storage box 2 is communicated with the air intake pipe 4 through this slot. A heating pipe 5 is installed in the air intake pipe 4. The heating pipe 5 is a continuous S-shaped pipe structure. The lengths of the four heating pipes 5 decrease in sequence from top to bottom, and the temperature of the heated air gradually decreases. An air intake fan 7 is symmetrically installed on the rear side of the diversion frame 6 by bolts. The storage cabinet 1 is provided with a return pipe 8 on the left and right sides of the storage box 2. The front end of the return pipe 8 is communicated with the inside of the storage cabinet 1 but is not connected. The rear end of the return pipe 8 is communicated and connected to the diversion frame 6. The heating pipe 5 and the air intake fan 7 are both electrically connected to the control board 101.

[0024] To use this device, first pull the storage boxes 2 forward from the chute of the storage cabinet 1. Then, place the asphalt test specimens into each storage box 2 according to their type. Once placed, the boxes 2 are pushed back into the chute of the storage cabinet 1. The operator then precisely controls the temperature of each heating tube 5 using the control panel 101. Once the temperature is adjusted, the intake fan 7 and the heating tube 5 are activated. Once activated, the intake fan 7 draws outside air into the diversion frame 6 and the return pipe 8. After the air enters the air intake pipe 4, it is heated by the heating tube 5. Since the heating tube 5 has an S-shaped structure, it can effectively increase the contact area between the air and the heating tube 5 and improve the heating efficiency. The heated hot air then enters the storage box 2, thereby maintaining the temperature inside the storage box 2 and ensuring the stability of the asphalt sample during storage. Since the length of each heating tube 5 is different, its resistance and the amount of heat generated are also different. Under the same current and power-on time conditions, the greater the resistance, the more heat is generated. The longer the heating tube 5, the larger the resistance, the more heat is generated, and the temperature of the heated air is higher; conversely, the shorter the heating tube 5, the smaller the resistance, the less heat is generated, and the temperature of the heated air is lower. Through this design, the temperature of the areas where different storage boxes 2 are located is accurately controlled, that is, the function of zoned temperature control is realized.

[0025] like Figure 5-Figure 8 As shown, it also includes a lifting baffle 9, a guide rod 10, a tension spring 12 and a V-shaped plate 14. Guide rods 10 are welded on the left and right sides of the bottom of the air intake pipe 4. A lifting baffle 9 is slidably connected between each corresponding guide rod 10. The lifting baffle 9 moves upward to block the front port of the air intake pipe 4. A tension spring 12 is sleeved on the guide rod 10. The upper and lower ends of the tension spring 12 are respectively connected to the lifting baffle 9 and the air intake pipe 4. A through hole 13 is opened at the lower end of the lifting baffle 9. The rear side of each storage box 2 is connected to a V-shaped plate 14 by screws. The V-shaped plate 14 passes through the corresponding through hole 13, so that the lifting baffle 9 is in an open state and the tension spring 12 is in a stretched state.

[0026] During use of the device, the heating tube 5 and the air intake fan 7 continue to work to store the asphalt sample at a controlled temperature. When the storage box 2 needs to be pulled out to the front to take out or store the asphalt sample, first, the storage box 2 moves forward, which will drive the V-shaped plate 14 to move forward. This forward movement will cause the lifting baffle 9 to gradually move upward along the guide rod 10 under the action of its own inclined surface and the restoring action of the tension spring 12, thereby closing the front end of the corresponding air intake pipe 4. In this way, the hot air in the air intake pipe 4 will not be sprayed out from this storage box 2, avoiding harm to the staff due to the hot air when the storage box 2 is pulled out. When the storage box 2 is pushed back to the rear, the storage box 2 drives the V-shaped plate 14 to move rearward, and the V-shaped plate 14 will be aligned with the through hole 13 on the lifting baffle 9, and then inserted into the through hole 13. As the V-shaped plate 14 moves, its inclined surface structure pushes the lifting baffle 9 to move downward and open, and the tension spring 12 returns to the stretched state. In this way, the hot air in the air intake pipe 4 can normally enter the storage box 2, and the device returns to normal working condition.

[0027] like Figure 8 As shown, a notch 15 is provided at the bottom of the V-shaped plate 14, and the notch 15 is engaged with the lifting baffle 9. The engagement of the notch 15 with the lifting baffle 9 can ensure that the storage box 2 will not slide easily in the front and rear directions when it is in a natural state. When the storage box 2 needs to be pulled out, it only takes a slight pull on the storage box 2 to disengage the V-shaped plate 14 from the notch 15.

[0028] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention may be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
