Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of conductive agent production and processing equipment, specifically to a structure of a guide plate for uniform hot air distribution inside a conductive agent drying oven. Background Technology
[0002] Drying is an essential and crucial step in the production of conductive agents. Its purpose is to remove moisture or other solvents from the conductive agents to ensure product quality and performance.
[0003] Currently, most conductive agent drying ovens use hot air drying. However, in actual use, the uneven distribution of hot air inside the drying oven is a prominent problem.
[0004] Existing drying ovens have relatively simple hot air guiding structures, typically consisting of only simple baffles at the air inlet. This lack of effective regulation of the hot air flow direction leads to variations in the flow rate and velocity of the hot air in different areas of the drying oven, resulting in uneven heating of the conductive agent during the drying process. Uneven heating not only prolongs drying time and reduces production efficiency but may also cause some conductive agents to be over-dried, affecting their conductivity and physicochemical properties. Meanwhile, other conductive agents may be under-dried, failing to meet quality standards.
[0005] Furthermore, uneven hot air distribution can easily create localized high or low temperature zones within the drying chamber, increasing energy consumption and posing certain safety hazards. Therefore, developing a guide plate structure that enables uniform hot air distribution within the drying chamber is of great significance for improving the drying quality and production efficiency of conductive agents. Utility Model Content
[0006] The purpose of this invention is to provide a guide plate structure for uniform hot air distribution inside a conductive agent drying oven, so as to solve the defects mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution:
[0008] The conductive agent drying oven has a hot air distribution guide plate structure, including a drying oven body. The bottom side of the drying oven body is provided with a hot air inlet hole. Multiple guide plates are fixedly installed on the bottom wall of the drying oven body. The length of the multiple guide plates increases sequentially from left to right. Multiple guide holes are provided on the guide plates. Multiple turbulence protrusions are fixedly installed on the upper surface of the guide plates. The surface of the guide plates is provided with a high temperature resistant and anti-corrosion coating. The guide plates are arranged in an upward inclined position.
[0009] Preferably, the multiple guide plates are arranged in parallel, and the guide holes on adjacent guide plates are staggered.
[0010] Preferably, the guide plate is inclined upward at 15 to 30 degrees, and the turbulence protrusion is hemispherical and evenly distributed on the guide plate.
[0011] Preferably, the guide hole is circular in shape, and the diameter of the hole gradually decreases from one side near the hot air inlet to the other side;
[0012] This setting allows the hot air to gradually slow down during its flow, ensuring uniform diffusion of the hot air within the drying chamber.
[0013] Preferably, the distance between two adjacent guide plates is equal and the spacing is between 5 and 10 cm, and the height of the turbulence protrusion is between 1 and 2 cm and the diameter is between 2 and 3 cm;
[0014] This feature helps control the flow space of hot air between adjacent guide plates, ensuring a uniform distribution of hot air; at the same time, the turbulence protrusions can effectively disrupt the flow direction of hot air, making the hot air more evenly distributed in the drying chamber.
[0015] Preferably, a hot air inlet pipe is fixedly installed at the hot air inlet hole, and multiple support pads are fixedly installed at the bottom of the drying oven body.
[0016] Preferably, the inner wall of the drying oven body is provided with a plurality of mesh partitions. The mesh partitions include a rectangular frame fixedly installed on the inner wall of the drying oven body. A plurality of horizontal rods and a plurality of vertical rods are fixedly installed between the left and right inner walls and between the front and rear inner walls of the rectangular frame, respectively. A mesh plate is provided between adjacent horizontal rods and adjacent vertical rods.
[0017] Preferably, the top of the drying oven body is provided with an air outlet pipe, and a serpentine tube is provided inside the air outlet pipe. Water outlet pipe and water inlet pipe are respectively fixedly installed at both ends of the serpentine tube, which pass through the air outlet pipe.
[0018] Compared with the prior art, the beneficial effects of this utility model are:
[0019] 1. This utility model achieves effective guidance and diversion of hot air by setting a guide plate with progressively increasing length, upward inclination and staggered distribution of guide holes, so that the flow rate of hot air in different areas of the drying chamber tends to be balanced, avoiding local overheating caused by concentrated hot air, and achieving the effect of ensuring uniform heating of conductive agent and improving drying quality.
[0020] 2. This utility model achieves precise control and flow direction disturbance of hot air velocity by designing the guide hole with the diameter gradually decreasing from one side near the hot air inlet to the other side, combined with the evenly distributed hemispherical turbulence protrusions on the guide plate. This promotes the slow and even diffusion of hot air in the chamber, thereby enhancing the uniformity of hot air distribution and improving drying efficiency.
[0021] 3. This utility model achieves the protection of the guide plate, stable support of the drying box, orderly placement of the conductive agent, and recovery and utilization of waste heat by setting a high-temperature resistant and anti-corrosion coating on the surface of the guide plate, installing support pads at the bottom of the drying box, setting a mesh partition inside the box, and installing an air outlet pipe with a serpentine tube at the top. This results in extending the service life of the equipment, reducing energy consumption, and ensuring the safe and orderly operation of the drying process. Attached Figure Description

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0030] Please see Figures 1-3 This utility model provides a technical solution: a guide plate structure for uniform hot air distribution inside a conductive agent drying oven, including a drying oven body 1. A hot air inlet hole 10 is provided on the bottom side of the drying oven body 1, so that hot air can stably enter the drying oven and provide a heat source for drying the conductive agent. At the same time, the position design of the hot air inlet hole 10 is conducive to the subsequent guidance and diffusion of hot air inside the oven, creating conditions for uniform drying.
[0031] like Figure 1 and Figure 3As shown, multiple guide plates 3 are fixedly installed on the bottom wall of the drying oven body 1. The length of the multiple guide plates 3 increases sequentially from left to right. As the hot air flows from left to right, it comes into contact with guide plates 3 of different lengths, so as to achieve more comprehensive guidance and diversion of the hot air, effectively avoid the hot air from concentrating in a certain area, make the hot air more evenly distributed in the oven, and ensure that the conductive agent is heated evenly.
[0032] like Figure 1 and Figure 3 As shown, the guide plate 3 is provided with multiple guide holes 30. The multiple guide plates 3 are arranged in parallel, and the guide holes 30 on two adjacent guide plates 3 are staggered, so that the hot air is changed multiple times when passing through the guide holes 30, realizing multi-stage diversion, further promoting the diffusion of hot air in different directions in the drying oven body 1, and enhancing the uniformity of hot air distribution.
[0033] like Figure 1 and Figure 3 As shown, multiple turbulence protrusions 31 are fixedly installed on the upper surface of the guide plate 3. The turbulence protrusions 31 are hemispherical and evenly distributed on the guide plate 3. When the hot air flows through the guide plate 3, it is obstructed and disturbed by the turbulence protrusions 31, forming a complex and turbulent airflow. This breaks the uneven flow state that the hot air may originally exist, promotes the even distribution of hot air in the drying chamber, and improves the drying effect of the conductive agent.
[0034] like Figure 3 As shown, a high-temperature resistant and corrosion-resistant coating 32 is provided on the surface of the guide plate 3. The guide plate 3 is set in an upward inclined position, which enables the guide plate 3 to resist the baking of high-temperature hot air and the erosion of corrosive gases, extend the service life of the guide plate 3, reduce equipment maintenance costs and downtime caused by damage to the guide plate, and ensure the continuous and stable operation of the drying work.
[0035] In this embodiment, the guide plate 3 is set at an upward tilt of 15 to 30 degrees to guide the hot air to flow upward, avoid the hot air directly impacting the conductive agent, and prevent local overheating; at the same time, the hot air gradually diffuses during the upward process, and together with the guide hole 30 and the turbulence protrusion 31, the hot air is evenly distributed in the space inside the drying oven body 1.
[0036] like Figure 3 As shown, the guide hole 30 is circular in shape, and the diameter of the hole gradually decreases from one side near the hot air inlet hole 10 to the other side. This allows the hot air to gradually slow down as the diameter of the guide hole 30 decreases, thus preventing the hot air flow rate from being too fast and causing local overheating. Furthermore, the slowed-down hot air has more time and space to diffuse evenly within the drying chamber, ensuring the uniformity and stability of the drying process.
[0037] Specifically, the distance between two adjacent guide plates 3 is equal, and the spacing is between 5 and 10 cm. This controls the flow space of hot air between adjacent guide plates 3, allowing the hot air to move stably in this space, such as splitting and turbulence. This avoids the hot air distribution effect being affected by the space being too large or too small, and ensures that the hot air is evenly distributed in the drying oven. The height of the turbulence protrusion 31 is between 1 and 2 cm, and the diameter is between 2 and 3 cm. The turbulence protrusion 31 can effectively disrupt the flow direction of the hot air, making the hot air more evenly distributed in the drying oven.
[0038] like Figure 1 As shown, a hot air inlet pipe 11 is fixedly installed at the hot air inlet hole 10, so that the hot air can enter the drying chamber body 1 more smoothly and stably, reducing the loss and turbulence of hot air at the inlet; at the same time, the hot air inlet pipe 11 can be connected to different hot air source equipment according to actual needs, improving the adaptability of the equipment; multiple support pads 12 are fixedly installed at the bottom of the drying chamber body 1, so that the drying chamber body 1 is kept at a certain distance from the ground, which facilitates the air circulation at the bottom of the equipment and prevents damage to the drying chamber body 1 caused by factors such as dampness or water accumulation at the bottom.
[0039] like Figure 1 and Figure 2 As shown, multiple perforated partitions 2 are provided on the inner wall of the drying oven body 1. Each perforated partition 2 includes a rectangular frame 20 fixedly installed on the inner wall of the drying oven body 1. Multiple horizontal rods 21 and multiple vertical rods 22 are fixedly installed between the inner walls of the left and right sides and between the inner walls of the front and rear sides of the rectangular frame 20, respectively. A perforated plate 23 is provided between adjacent horizontal rods 21 and adjacent vertical rods 22. The perforated plate 23 has a perforated plate structure, which allows the conductive agent to be placed in layers, increasing the utilization rate of the drying space. The perforated structure allows hot air to penetrate the partition, ensuring that each layer of conductive agent can fully contact the hot air, improving drying efficiency and uniformity.
[0040] like Figure 1 As shown, the top of the drying oven body 1 is provided with an air outlet pipe 13, and a serpentine pipe 14 is provided inside the air outlet pipe 13. Water outlet pipe 141 and water inlet pipe 142 are respectively fixedly installed at both ends of the serpentine pipe 14, which pass through the air outlet pipe 13. The water flow in the serpentine pipe 14 is used to exchange heat with the high temperature gas discharged from the air outlet pipe 13, so as to realize the recovery and utilization of the waste heat of the discharged hot air, reduce energy consumption, and at the same time, it can also cool down the discharged gas and reduce thermal pollution to the environment.
[0041] When using the conductive agent drying oven with the uniform hot air distribution guide plate structure of this utility model, first place the conductive agent container in layers on the mesh partition 2. The structure of the mesh partition 23 ensures that each layer of conductive agent can fully contact the hot air. Then connect the hot air inlet pipe 11 to the hot air source equipment, start the hot air system, and the hot air enters the drying oven body 1 stably through the hot air inlet hole 10.
[0042] After the hot air enters, it first comes into contact with the guide plates 3 on the bottom wall, which are of progressively increasing length from left to right. The guide plates 3 of different lengths initially guide and divert the hot air. Then, the hot air passes through the staggered guide holes 30 on the guide plates 3 and its flow direction is changed multiple times to achieve multi-stage diversion and diffusion. During the process of passing through the guide plates 3, the hemispherical turbulence protrusions 31 obstruct and interfere with the hot air, causing it to form a complex airflow. At the same time, the upwardly inclined guide plates 3 guide the hot air to flow upward and gradually diffuse. In conjunction with the guide holes 30 with gradually decreasing diameter, the hot air is slowed down to ensure uniform distribution in the chamber.
[0043] The high-temperature gas generated during the drying process is discharged from the top air outlet pipe 13. The water flow in the serpentine pipe 14 inside the air outlet pipe 13 exchanges heat and recovers the residual heat. After drying, the hot air system is turned off and the dried conductive agent is taken out.
[0044] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
