Description

Technical Field

[0001] This application relates to the technical field of household appliances, and particularly to a lithium battery material dryer. Background Art

[0002] With the rapid development of the new energy vehicle industry, lithium batteries, as their core components, have a crucial impact on the performance of new energy vehicles. Therefore, the drying treatment of lithium battery materials has become an important link in improving the performance and quality of lithium batteries. As a result, the demand for lithium battery material dryers is increasing continuously. With the continuous progress and innovation of technology, the performance and quality of lithium battery material dryers are also improving continuously, providing strong support for the development of the lithium battery industry.

[0003] To improve the drying efficiency of the dryer, two relatively independent heat exchange systems can be set up. At the same time, for the convenience of air return, the air return ports of the two systems are generally arranged side by side at the top of the machine body. As a result, the air duct of the lower heat exchange system becomes longer, and the fan speed is insufficient, resulting in uneven heat exchange and even ice formation, which is likely to affect the overall operation of the unit. Utility Model Content

[0004] The purpose of the embodiments of this application is to provide a lithium battery material dryer. In view of the situation that the air duct of the lower heat exchange system is too long, a flow dividing plate is provided, which can make the air flowing to the first evaporator relatively uniform, so as to achieve uniform heat exchange.

[0005] To achieve the above purpose, this application adopts the following technical solutions:

[0006] On the one hand, a lithium battery material dryer is provided, including: a machine body and two heat exchange systems. The two heat exchange systems are installed in parallel up and down in the machine body. The lower heat exchange system is the first heat exchange system. The top of the machine body is provided with a first air return port and a first air discharge port;

[0007] The first heat exchange system includes a first sensible heat exchanger, a first air return duct, a first air discharge duct and a first evaporator. The first sensible heat exchanger has a conductive A side and B side. One end of the first air return duct is connected to the first air return port, and the other end is connected to the A side. One end of the first air discharge duct is connected to the first air discharge port, and the other end is connected to the B side. The first evaporator is installed in the first air discharge duct;

[0008] A plurality of flow dividing plates are further arranged in the first air discharge duct. The plurality of flow dividing plates are arranged between the first sensible heat exchanger and the first evaporator and are spaced along the air flow direction of the first air discharge duct.

[0009] Further, the first exhaust air duct has an articulated first segment and second segment. The air inlet surface of the first segment faces the B surface, and the air outlet surface of the first segment faces the air inlet surface of the second segment and is smaller than the air inlet surface of the first segment. The first evaporator is disposed in the second segment, and a plurality of the flow dividing plates are disposed at the connection of the first segment and the second segment.

[0010] Further, an air outlet cavity is formed in the second segment. The air outlet cavity is located at the rear side of the air outlet surface of the first evaporator, and air outlet openings are formed in the side wall surface of the air outlet cavity.

[0011] Further, first air guiding plates are inclined on both sides of the air outlet openings. The first air guiding plates guide the air flow in the air outlet cavity to flow towards the air outlet openings.

[0012] Further, a second air guiding plate is disposed on the side of the air outlet cavity away from the first evaporator. The second air guiding plate is arc-shaped, and the inner arc surface of the second air guiding plate faces the air outlet openings.

[0013] Further, the first segment includes a first side wall, and the second segment includes a second side wall. One side of the first side wall is connected to the first sensible heat exchanger, and the other side is articulated with the second side wall. An included angle is formed between the first side wall and the second side wall.

[0014] Further, the plurality of the flow dividing plates include a first dividing plate arranged parallel to the second side wall and two second dividing plates arranged parallel to the first side wall.

[0015] Further, a fan frame is further included. The fan frame is installed on the outer side surface of the machine body.

[0016] Further, a support member is disposed at the bottom of the fan frame.

[0017] Further, a buffer member is disposed at the bottom of the support member.

[0018] The beneficial effects of the present application are as follows: By providing the flow dividing plates, the air flowing towards the first evaporator can be relatively uniform, thereby improving the heat exchange efficiency; Since the air flow is more uniform, the heat exchange non-uniformity and icing phenomena caused by too long air ducts and insufficient fan speed are reduced, and the overall operation stability of the unit is improved. In addition, more efficient heat exchange means that the drying process can be more precise and rapid, thereby improving the drying quality of the lithium battery materials. Generally speaking, the lithium battery material dryer significantly improves the heat exchange efficiency and drying quality by optimizing the heat exchange system design and introducing the flow dividing plates, provides strong technical support for the development of the lithium battery industry, and this design has strong versatility and practicability and can adapt to the drying requirements of different specifications and types of lithium battery materials.

Detailed Embodiments

[0027] To make the technical problems solved by the present application, the technical solutions adopted, and the achieved technical effects clearer, the following further elaborates on the technical solutions of the embodiments of the present application in detail. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all of them. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts belong to the scope of protection of the present application.

For example, it may be a fixed connection, a detachable connection, or integrated; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two components or the interaction relationship between two components.

[0029] In the present application, unless otherwise clearly defined and limited, the first feature being "above" or "below" the second feature may include the direct contact between the first and second features, or may include the situation where the first and second features are not in direct contact but in contact through other features between them. Moreover, the first feature being "above", "over", and "on top of" the second feature includes that the first feature is directly above and obliquely above the second feature, or merely indicates that the horizontal height of the first feature is higher than that of the second feature. The first feature being "below", "beneath", and "underneath" the second feature includes that the first feature is directly below and obliquely below the second feature, or merely indicates that the horizontal height of the first feature is lower than that of the second feature.

[0030] As Figures 1-6 shown, this embodiment provides a lithium battery material dryer, which includes: a machine body 1 and two sets of heat exchange systems. The two sets of heat exchange systems are installed in parallel up and down in the machine body 1. The heat exchange system located below is the first heat exchange system 2. A first air return port 204 and a first air discharge port 205 are opened at the top of the machine body 1.

[0031] The first heat exchange system 2 includes a first sensible heat exchanger 201, a first air return duct 202, a first air discharge duct 203, and a first evaporator 207. The first sensible heat exchanger 201 has a conducting surface A and a surface B. One end of the first air return duct 202 is connected to the first air return port 204, and the other end is connected to the surface A. One end of the first air discharge duct is connected to the first air discharge port 205, and the other end is connected to the surface B. The first evaporator 207 is installed in the first air discharge duct 203. A plurality of flow dividing plates 206 are further arranged in the first air discharge duct 203. The plurality of flow dividing plates 206 are arranged between the first sensible heat exchanger 201 and the first evaporator 207 and are spaced along the air flow direction of the first air discharge duct 203.

[0032] Based on the above solution, the dried air enters the first return air duct 202 through the first return air inlet 204 at the top of the machine body 1, and then undergoes preliminary heat exchange through the A side of the first sensible heat exchanger 201, resulting in a temperature drop. After that, this air enters the first exhaust duct 203, where it encounters multiple flow splitting plates 206. The design of these flow splitting plates 206 ingeniously divides the air flow into multiple smaller flow bundles, ensuring that the air can flow more evenly through the first evaporator 207, achieving a more efficient heat exchange process. The air after sensible heat exchange and evaporative heat exchange has its temperature further reduced and finally is discharged from the machine body 1 through the first exhaust outlet 205. The beneficial effects of this design are remarkable. Firstly, by setting the flow splitting plates 206, the air flowing towards the first evaporator 207 can be relatively uniform, thus improving the heat exchange efficiency. Secondly, due to the more uniform air flow, the uneven heat exchange and icing phenomena caused by the overly long air duct and insufficient fan speed are reduced, improving the overall operating stability of the unit. In addition, more efficient heat exchange means that the drying process can be more precise and rapid, thereby enhancing the drying quality of lithium battery materials. Generally speaking, this lithium battery material dryer significantly improves the heat exchange efficiency and drying quality by optimizing the heat exchange system design and introducing the flow splitting plates 206, providing strong technical support for the development of the lithium battery industry. Moreover, this design has strong versatility and practicability and can adapt to the drying requirements of different specifications and types of lithium battery materials.

[0033] Further, the first exhaust duct 203 has a connected first section 2031 and second section 2032. The air inlet surface of the first section 2031 faces the B side, and the air outlet surface of the first section 2031 faces the air inlet surface of the second section 2032 and is smaller than the air inlet surface of the first section 2031. The first evaporator 207 is arranged in the second section 2032, and multiple flow splitting plates 206 are arranged at the connection between the first section 2031 and the second section 2032. The air inlet surface of the first section 2031 faces the B side of the first sensible heat exchanger 201, ensuring that the cold air coming out of the sensible heat exchanger can smoothly enter. The air outlet surface of the first section 2031 faces the air inlet surface of the second section 2032. It should be noted that the area of the air outlet surface of the first section 2031 is smaller than its air inlet surface. This design helps to preliminarily compress the air flow to a certain extent, preparing for subsequent flow splitting and heat exchange. The first evaporator 207 is ingeniously arranged in the second section 2032. In this way, the air flow after preliminary compression and guidance will first encounter multiple flow splitting plates 206 after entering the second section 2032. These flow splitting plates 206 are carefully arranged at the connection between the first section 2031 and the second section 2032, and their function is to further divide the air flow into multiple smaller flow bundles, ensuring that the air can flow through the first evaporator 207 more evenly and fully, thus achieving a more efficient and uniform heat exchange process.

[0034] Furthermore, an air outlet cavity 2036 is formed within the second segment 2032. The air outlet cavity 2036 is located at the rear side of the air outlet surface of the first evaporator 207. An air outlet 2035 is provided on the side wall surface of the air outlet cavity 2036. Within the second segment 2032, in addition to the first evaporator 207, an air outlet cavity 2036 is also formed. This air outlet cavity 2036 is cleverly located at the rear side of the air outlet surface of the first evaporator 207, and its function is to collect and direct the air after heat exchange through the first evaporator 207. The air outlet 2035 is provided on the side wall surface of the air outlet cavity 2036. These air outlets 2035 communicate with the first air outlet 205 at the top of the machine body 1. When the air completes heat exchange within the first evaporator 207, it will enter the air outlet cavity 2036, and be further sorted and directed within it, and then be discharged from the machine body 1 through the air outlets 2035 on the side wall surface. The design of the air outlet cavity 2036 not only helps to ensure that the air after heat exchange can be discharged smoothly, but also can reduce the turbulence and eddy current of the air flow to a certain extent, improving the stability and uniformity of the air flow. At the same time, it also makes the internal structure of the entire dryer more compact and reasonable, improving the overall performance and reliability of the equipment.

[0035] Meanwhile, first air guiding plates 2037 are inclinedly arranged on both sides of the air outlet 2035. The first air guiding plates 2037 guide the air flow within the air outlet cavity 2036 towards the air outlet 2035. When the air flows within the air outlet cavity 2036, it will be guided and restricted by the first air guiding plates 2037, making the direction of the air flow more definite and concentrated. This guiding effect not only helps to reduce the turbulence and eddy current of the air flow, improving the stability and uniformity of the air flow, but also can ensure that the air can make full use of the area of the air outlet 2035 to achieve a more efficient air exhaust effect.

[0036] In addition, the inclination angles of the first air guiding plates 2037 are also carefully calculated to ensure that they can maximize the guiding effect while avoiding excessive resistance to the air flow. This design not only improves the overall performance of the dryer, but also makes the operation of the equipment more energy-saving and efficient.

[0037] To further improve the exhaust efficiency of the air outlet 2035 and the uniformity of air flow, a second air guide plate 2038 is also provided on the side of the air outlet cavity 2036 facing away from the first evaporator 207 in this lithium-ion material dryer. This design reflects an in-depth understanding and application of the principles of aerodynamics. The second air guide plate 2038 is arc-shaped, and its inner arc surface faces the air outlet 2035. This shape design enables that when air flows out of the air outlet cavity 2036 and passes through the second air guide plate 2038, it will be subjected to an arc-shaped guiding force. This guiding force not only helps to accelerate the air flow towards the air outlet 2035, but also enables the air flow to be more evenly distributed in each area of the air outlet 2035 during the outflow process. Specifically, the arc-shaped second air guide plate 2038 can form a structure similar to a diffuser, enabling the air to gradually spread and fill the entire air outlet 2035 when flowing out. In this way, even if the area of the air outlet 2035 is relatively large, it can ensure the uniformity and stability of the air flow, and avoid the situation of excessive or too small local air flow.

[0038] In some embodiments, to further optimize the air flow path in the first exhaust duct 203 and improve the heat exchange efficiency, the first section 2031 and the second section 2032 of this lithium-ion material dryer have made innovations in the structural design. Specifically, the first section 2031 includes a first side wall 2033, and the second section 2032 includes a second side wall 2034. These two side walls are not completely parallel at the junction, but form a certain angle. This design enables one side of the first side wall 2033 to be closely connected to the first sensible heat exchanger 201, ensuring that cold air can smoothly enter the first section 2031, and the other side is connected to the second side wall 2034 at a certain angle, forming a gradually expanding channel. This angle design has a positive impact on air flow. On the one hand, it can guide the air flow to a certain extent, making it flow more smoothly towards the second section 2032 and the first evaporator 207. On the other hand, the angle can also change the speed and direction of the air flow, promoting the heat exchange between the air and the first evaporator 207 and improving the heat exchange efficiency.

[0039] In addition, the angle design can also be adjusted according to specific application scenarios and requirements. For example, in the case where it is necessary to improve the heat exchange efficiency, the angle can be appropriately reduced to make the air flow pass through the first evaporator 207 more concentratedly. And in the case where it is necessary to reduce the wind resistance and noise, the angle can be appropriately increased to make the air flow flow more smoothly.

[0040] It should be noted that when further refining the design of the flow splitter plate 206, the lithium battery material dryer adopts a more precise layout method. Specifically, among the multiple flow splitter plates 206, there is at least one first splitter plate 2061 arranged parallel to the second side wall 2034, and two second splitter plates 2062 arranged parallel to the first side wall 2033. The advantage of this layout is that after the air flows out from the B surface of the first sensible heat exchanger 201, it will immediately enter the first section 2031 of the first exhaust duct 203. In the first section 2031, the air will encounter both the first splitter plate 2061 arranged parallel to the second side wall 2034 and the second splitter plate 2062 arranged parallel to the first side wall 2033. These two splitter plates function simultaneously to divide and guide the air flow. The first splitter plate 2061 and the second splitter plate 2062 are adapted to the connection angle of the two side walls, enabling the air to be more reasonably and evenly dispersed, ensuring the uniform distribution and efficient flow of the air flow in the first exhaust duct 203. This design of simultaneous flow splitting not only improves the uniformity and stability of the air flow but also helps to improve the heat exchange efficiency and drying quality of the dryer. Because when the air flow flows more evenly through the first evaporator 207, it can more fully exchange heat with the evaporator, thereby achieving more efficient heat transfer and a more uniform drying effect.

[0041] In addition, this layout of the flow splitter plate 206 also has a certain degree of flexibility. In practical applications, the number and position of the flow splitter plate 206 can be finely adjusted according to the specific size and shape of the first exhaust duct 203, as well as the position and size of the first evaporator 207, in order to achieve the best heat exchange effect.

[0042] Furthermore, it also includes a fan frame 3. The fan frame 3 is installed on the outer side of the machine body 1. A support member 301 is provided at the bottom of the fan frame 3, and a buffer member 302 is provided at the bottom of the support member 301. The fan frame 3 is installed on the outer side of the machine body 1, which not only provides a stable installation platform for the fan but also optimizes the layout of the entire dryer. Support members 301 are specifically provided at the bottom of the fan frame 3. These support members 301 not only bear the weight of the fan frame 3 and the fan installed thereon but also ensure the stability of the fan during operation. More importantly, buffer members 302 are equipped at the bottom of the support members 301. These buffer members 302 are usually made of elastic materials such as rubber pads and springs. They can effectively absorb and relieve vibrations and impacts during the operation of the fan, thereby reducing the noise and vibration effects of the fan on the machine body 1 and the surrounding environment. The addition of the buffer members 302 not only improves the operating stability of the dryer but also extends the service life of the fan and the entire equipment. At the same time, it also makes the dryer quieter during operation, providing a more comfortable working environment for the operator.
