Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of drying articles, and particularly relates to a drying box and a flow guiding system. BACKGROUND

[0002] With the development of science and technology and the improvement of living standards, drying boxes, as an important equipment, are widely used in many fields. In recent years, with the popularization of 3D printing technology, the drying demand of 3D printing consumables (such as PLA, ABS and other plastic filaments) has also increased. These consumables are prone to moisture absorption in a humid environment, which may cause problems such as bubbles and cracks during printing, seriously affecting the printing quality and yield. Therefore, efficient drying equipment is crucial to ensure the quality of 3D printing materials.

[0003] However, the existing drying box has some significant problems during use, especially the uneven heat conduction. In the traditional design of drying box, drying is usually carried out by using drying agent packets or direct blowing of hot air. Although these methods are simple and easy to implement, they may lead to uneven distribution of hot air in actual operation, especially in large drying boxes.

[0004] For example, although the method of using drying agent packets can absorb moisture in the air, the placement position and quantity of the drying agent packets are difficult to control accurately, which may lead to uneven drying effect. The method of direct blowing of hot air can quickly increase the temperature, but since the hot air is mainly concentrated near the heating element, the temperature is lower far from the heating element, thereby forming a significant temperature gradient. Such temperature difference not only reduces the drying efficiency, but also may cause uneven drying of the materials, affecting the product quality.

[0005] For 3D printing consumables, local high temperature may cause the material to melt or deform, and low temperature cannot fully remove moisture, which may seriously affect the final printing effect, thereby greatly limiting the application range and development space of the drying box.

[0006] Based on this, the utility model provides a drying box and a flow guiding system. UTILITY MODEL CONTENT

[0007] In order to solve the above problems in the prior art, i.e., the uneven drying and local high temperature of the drying box in the prior art, the utility model provides a drying box and a flow guiding system.

[0018] In some preferred embodiments, the height of the cold air duct gradually decreases from the turbofan connected therewith to the guide plate.

[0032] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific examples described herein are only intended to explain the related application, and not to limit the application. In addition, it should be noted that only parts related to the application are shown in the drawings for ease of description.

[0033] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the accompanying drawings and examples.

[0034] As Figures 1-5 shown, the utility model first embodiment provides a drying box, including the box 1, install at least two vortex fan 2 and the flow guide device 3 in the box 1, the flow guide device 3 includes the cold air duct 31, hot air duct 32 and the flow guide plate 33 installed in the box 1;

[0035] One of vortex fan 2's air outlet is sealedly connected with cold air duct 31 and communicates, and the air outlet of another vortex fan 2 is sealedly connected with hot air duct 32 and communicates;

[0036] The air outlet of cold air duct 31 and hot air duct 32 is equipped with flow guide plate 33 at interval distance cover, and the cold air in the air outlet of cold air duct 31 is guided to the air outlet of hot air duct 32 by flow guide plate 33, and the hot air is blown away and guided to the inside of box 1.

[0037] Wherein, the box 1 in the embodiment is made of high-temperature-resistant, corrosion-resistant material, has good heat preservation performance, to reduce heat loss. The internal space is designed according to the size of the material to be dried, to ensure sufficient capacity.

[0038] As Figure 1 shown, the box 1 is composed of frame and panel, and the panel is installed between two adjacent frames. In order to facilitate the observation of the drying goods in the box 1, the panel can be made of transparent material.

[0039] Wherein, the ground of the box 1 is provided with anti-skid convex, and the skilled person in the art can select any one surface to be provided with a cover door, which is movably connected with the frame, and can be hingedly connected.

[0040] As Figures 3-4 shown, at least two vortex fans 2 are provided, one of which is responsible for sucking cold air in the environment and blowing out through the cold air duct 31; the other is responsible for sucking air and heating through the heating module 4, and then uniformly distributing to the box through the hot air duct 32.

[0041] As Figure 4 shown, the height of the cold air duct 31 in the embodiment gradually decreases from the vortex fan 2 connected thereto to the direction of the flow guide plate 33. By gradually reducing the height of the cold air duct 31, the gravitational and aerodynamic effects can be utilized to facilitate the smooth flow of cold air to the flow guide plate 33. This design helps to reduce the resistance of cold air in the air duct and improve the flow speed and uniformity of cold air.

[0042] In addition, since the cold air flows more smoothly, the power required by the vortex fan 2 can be reduced, thereby reducing energy consumption. This not only saves energy, but also reduces operating costs.

[0043] The hot air duct 32 is used to ensure that the hot air can uniformly cover the entire drying area, avoiding local overheating.

[0044] The guide plate 33 is installed at the air outlet of the cold air duct 31 and the hot air duct 32, used to guide the mixing of cold air and hot air, and make the mixed air more evenly dispersed in the entire box. The design of the guide plate 33 makes the cold air and hot air pre-mixed, which helps to smooth the temperature gradient and ensure more uniform temperature in the box.

[0045] As Figure 4 shown, the heating module 4 in the embodiment can be an electric heating wire, an infrared heater or other high-efficiency heating element. The heating module 4 can uniformly heat the air passing through the hot air duct 32, ensuring uniform hot air temperature.

[0046] In the utility model, the material to be dried is placed in the box 1 and is subjected to uniform warm air action, accelerating water evaporation and achieving high-efficiency drying effect.

[0047] As a further explanation of the utility model, the cold air duct 31 and the hot air duct 32 are not connected to each other, and the technical effects are as follows:

[0048] Prevent hot air leakage:

[0049] Since the cold air duct and the hot air duct are not connected, direct leakage of hot air into the cold air duct can be effectively prevented. In this way, the temperature of the hot air in the hot air duct can be kept stable, and the temperature will not be lowered due to the mixing of cold air, thereby ensuring the heating effect of the hot air.

[0050] Improve temperature control accuracy:

[0051] The cold air and the hot air flow in their respective air ducts, which can more accurately control the temperature in each air duct. Through independent temperature sensors and heating modules, the temperature of the cold air and the hot air can be adjusted respectively, ensuring the uniformity and stability of the temperature in the box.

[0052] Avoid cold and hot air short circuit:

[0053] If the cold air duct and the hot air duct are connected, the cold air may directly enter the hot air duct, resulting in uneven hot air temperature. The design of not being connected avoids this cold and hot air short circuit phenomenon, ensuring that the cold air and the hot air have been fully mixed before entering the box, achieving ideal temperature distribution.

[0054] Improve drying efficiency:

[0055] The cold air and the hot air flow in their respective air ducts, which can more effectively utilize their respective characteristics. The cold air can be pre-mixed with the hot air before entering the box, forming uniform warm air, thereby improving the drying efficiency. At the same time, the hot air in the hot air duct can be concentrated to heat, ensuring rapid evaporation of moisture on the surface and inside the material.

[0056] The cold air duct 31 in the utility model is arranged below or below the hot air duct 32.

[0057] But in the embodiment, the cold air duct 31 is preferably arranged below the hot air duct 32, because the cold air is denser than the hot air and naturally sinks. Arranging the cold air duct below the hot air duct can utilize the effect of gravity to make the cold air more easily flow into the cold air duct and reduce energy loss. This can improve the flow efficiency of the cold air and ensure that the cold air can smoothly reach the flow guide plate 33;

[0058] The cold air enters from below and the hot air enters from above, forming a downward air flow distribution. This vertical air flow distribution helps the cold air and the hot air to fully mix at the flow guide plate 33, ensuring that the mixed air is more uniform and avoiding the problem of local temperature being too high or too low;

[0059] The vertically distributed cold air and hot air can reduce the temperature difference in the box. The cold air enters from below and the hot air enters from above, forming a stable temperature gradient, avoiding the problem of local temperature being too high or too low that may occur when the air is horizontally distributed;

[0060] Arranging the cold air duct below the hot air duct can simplify the design and installation of the air duct. This layout reduces pipe crossing and complex connections, reduces manufacturing and maintenance costs, and improves system reliability.

[0061] As shown in Figure 3 As a further explanation of the utility model, the flow guide plate 33 is provided with arc-shaped notches 331 on both sides of the corresponding part of the hot air duct 32, which are symmetrically arranged. The arc-shaped notches 331 are used to guide the blown hot air to the air inlet of the turbofan 2.

[0062] The design of the arc-shaped notches 331 can effectively guide the blown hot air back to the air inlet of the turbofan 2, forming a closed-loop air flow circulation system. This can ensure that the hot air circulates in the box multiple times, improve the utilization rate of air flow, and reduce energy loss;

[0063] By guiding the hot air backflow through the arc-shaped notches 331, the temperature distribution in the box can be better controlled. The multiple circulation of the hot air in the box helps to evenly distribute the temperature, reduces the problem of local temperature being too high or too low, and improves the drying effect;

[0064] The design of the arc-shaped notches 331 helps to reduce the temperature difference in the box. The multiple circulation of the hot air in the box can make the temperature more uniform, avoiding the problem of uneven drying caused by too large temperature difference;

[0065] The hot air backflow guided by the arc-shaped gap 331 can reduce the power consumption of the turbofan 2. Because the hot air circulates multiple times in the box, the need for cold air intake from the outside is reduced, thereby reducing the heating load of the heating module 4 and saving energy;

[0066] The hot air backflow guided by the arc-shaped gap 331 can reduce the risk of local overheating in the box. Uniform temperature distribution and stable airflow can avoid material deformation or damage caused by excessive temperature, improving the safety of the equipment.

[0067] As shown in Figure 2 As a further explanation of the present application, the heating module 4 is connected to the control module 5, which is used to control the heating temperature of the heating module 4, and the control module 5 is integrated on the box 1.

[0068] The temperature detection probe 6 is installed on the deflector 33, which is used to obtain the temperature in the box 1 in real time, and the temperature detection probe 6 is connected to the control module 5.

[0069] The control module 5 includes a microprocessor, a power management module, and an input / output interface.

[0070] Microprocessor: responsible for processing real-time temperature data provided by the temperature detection probe 6, and adjusting the heating power of the heating module 4 according to the preset temperature control strategy.

[0071] Power management module: responsible for providing stable power supply for the entire system to ensure normal operation of each component.

[0072] Input / output interface: including connection interface with temperature detection probe 6, control interface with heating module 4, and interface with user interface such as touch screen.

[0073] The control module 5 can accurately control the heating temperature of the heating module 4 by receiving real-time temperature data provided by the temperature detection probe 6, ensuring the stability and accuracy of the temperature in the box.

[0074] Real-time temperature monitoring and control can optimize the drying process. The control module 5 can adjust the heating power according to the actual temperature to ensure that the box always maintains the best drying temperature, thereby improving the drying efficiency and shortening the drying time.

[0075] By accurately controlling the heating temperature, unnecessary energy waste can be avoided. When the temperature reaches the set value, the control module 5 can reduce the power of the heating module 4 or turn off the heating module to save energy.

[0076] As shown in Figure 5 and Figure 6As further explained of the utility model, the inner wall of the opposite sides of the box 1 is provided with guide rail 7, the guide rail 7 is inserted with plugboard 8, the plugboard 8 covers the cold air duct air outlet, hot air duct air outlet and the air inlet of two turbofan 2, and the corresponding air outlet and air inlet are provided with corresponding through hole, to avoid blocking air outlet and air inlet, the deflector 33 is fixed on plugboard 8, the utility model can make the wind direction of deflection blow to the drying article, avoid the diffusion of hot air to its back, ensure that hot air can directly act on the drying article, improve the utilization efficiency of hot air. Avoiding the diffusion of hot air to the back can reduce heat loss, concentrate more heat on the drying article, speed up the drying speed and improve the drying efficiency.

[0081] The storage rack 9 can be provided with a groove for placing a drying agent bag. By combining the deflected hot air and the drying agent, the drying effect can be improved.

[0082] A consumable channel is arranged below the storage rack 9, and a through hole is arranged on one surface of the box 1 for conveying the consumables to the printing rack. The inner ring of the through hole is provided with a sealing ring for improving the overall sealing performance.
