Description
Technical Field
[0001] This utility model relates to the field of drying technology for high-speed train parts, and in particular to a drying device for processing high-speed train parts. Background Technology
[0002] In the manufacturing process of high-speed train components and related equipment, the drying process is one of the key steps to ensure product quality and performance. The quality of the drying directly affects the paint layer quality, structural strength, and service life of the components. However, in actual production, the problem of drying uniformity has always been a bottleneck restricting production efficiency and product quality. Due to the complex shapes and varying sizes of the components, traditional drying methods often fail to ensure uniform heat distribution on the component surface, resulting in some areas being over-dried while others are under-dried, seriously affecting the overall quality of the product.
[0003] Currently, there are various drying devices for high-speed train components and equipment on the market, but most of these devices still have significant shortcomings in terms of drying uniformity. For example, the background technology of a paint drying device for a high-speed train converter box described in CN213670267U mentions that traditional drying methods result in uneven heating of the paint layer on the box surface and poor paint layer formation due to differences in the degree of heating of different parts of the box during transport within the drying oven.
[0004] Similarly, the background technology of a drying device for processing high-speed train parts, as described in CN212378404U, points out that traditional drying devices mostly adopt a fixed drying structure, placing the parts on a fixed frame, blowing on one side, and drying the surface through heat in a sealed environment. This drying method results in poor drying effect on the surface of high-speed train parts, failing to dry them all-round, and leading to longer drying time. These problems not only reduce production efficiency but also increase the defect rate, causing economic losses to enterprises.
[0005] To address the aforementioned issues, a novel drying device for processing high-speed train parts is needed. This device ensures uniform heating of parts during the drying process, guaranteeing uniform formation of paint or coating layers, and improving the overall quality of the product. Using this technical solution, the drying uniformity of high-speed train parts and equipment is significantly improved, and the defect rate is drastically reduced, bringing significant economic and social benefits to enterprises.

[0013] Furthermore, a first positioning groove corresponding to the first positioning block and a second positioning groove corresponding to the second positioning block are provided in the track groove;
[0014] When the sliding component moves on the arc-shaped slide rail, the first positioning block and the second positioning block are located in the first positioning groove and the second positioning groove, respectively.

Detailed Implementation
[0030] The technical solution of this utility model will now be described with reference to the accompanying drawings. However, the described embodiments are only a part of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.
[0031] like Figures 1 to 7 As shown, this utility model provides a drying device for processing high-speed train parts, including a conveyor belt 1000 and a drying box 2000 disposed on the conveyor belt 1000;
[0032] A drying channel 2100 with an arch-shaped cross section is provided in the drying oven 2000. Several baking lamps 2110 that move along the arch-shaped cross section and a circular rail sliding assembly 2120 that moves the baking lamps 2110 in the drying channel 2100 are provided in the drying channel 2100.
[0033] A drying fan 2132 is installed in the drying oven 2000, and a waste gas recovery device 2400 is installed on the top of the drying oven 2000.
[0034] This drying device for EMU parts processing mainly consists of a conveyor belt 1000, a drying chamber 2000, a drying channel 2100, a baking lamp 2110, a circular rail sliding assembly 2120, a drying fan 2132, and a waste gas recovery device 2400. Its core function is to efficiently and uniformly dry EMU parts. Through the coordinated work of each component, the drying process is automated and precisely controlled, improving drying quality and production efficiency.
[0035] Specifically, the conveyor belt 1000, as the basic conveying component of the entire drying device, typically consists of a belt body, a drive roller, a driven roller, and a support structure. The belt body is generally made of high-temperature resistant and wear-resistant rubber or metal to ensure stable support of the vehicle components during long-term operation and to withstand the high-temperature environment generated during drying. The drive roller, driven by a motor, drives the belt body in cyclical motion, thereby achieving continuous conveying of the vehicle components. The driven roller supports and tensions the belt body, ensuring its stability during operation. The support structure provides a stable frame for the conveyor belt 1000, ensuring that the entire conveyor belt 1000 system does not sway or deviate during operation.
[0036] In this embodiment, the conveyor belt 1000 smoothly and continuously transports the train parts to be dried into the drying chamber 2000, and after drying, it transports the parts out of the drying device, realizing automated assembly line operation of the drying process. The effect is to improve production efficiency, reduce the time and labor intensity of manual handling of parts, and ensure the stability of the parts during transportation, avoiding damage caused by handling.
[0037] Specifically, the drying oven 2000 provides a relatively enclosed space for the drying process. It typically consists of a cabinet, an insulation layer, and a door. The cabinet is generally made of high-strength metal materials, such as stainless steel, to ensure its structural strength and durability. The insulation layer is located inside the cabinet and usually uses high-efficiency insulation materials such as aluminum silicate fiber and rock wool, which effectively reduces heat loss within the drying oven 2000, improves energy efficiency, and reduces energy consumption. The door facilitates the inspection and maintenance of the drying oven 2000's internal equipment and also serves as a seal to some extent, preventing heat leakage.
[0038] In this embodiment, the function of the drying chamber 2000 is to provide a stable and controllable environment for drying the train parts, ensuring the stability and consistency of drying quality, improving drying efficiency, and reducing the interference of the external environment on the drying process.
[0039] The drying channel 2100 is located inside the drying chamber 2000, and its cross-section is arched. This special shape design has several advantages. Structurally, the arched cross-section provides more internal space, facilitating the passage of train components within the channel, and also provides more space for the arrangement of the baking lamps 2110. From a thermodynamic perspective, the arched structure promotes uniform heat distribution, enabling good heat circulation within the channel, reducing heat dead zones, and thus improving the drying effect.
[0040] In this embodiment, the function of the drying channel 2100 is to provide a dedicated drying path for the train components, allowing them to be fully exposed to the irradiation of the baking lamp 2110 and the hot air drying from the drying fan 2132 as they pass through the channel. This ensures that the components receive comprehensive and uniform drying treatment during the drying process, improving drying quality and shortening drying time.
[0041] Specifically, the baking lamp 2110 is the main heat source of the drying device, typically employing either an infrared baking lamp 2110 or a quartz tube baking lamp 2110. The infrared baking lamp 2110 emits infrared rays of a specific wavelength, which have strong penetrating power and can directly act on the interior of the vehicle components, causing the moisture inside to evaporate rapidly, thus achieving fast drying. The quartz tube baking lamp 2110, on the other hand, has advantages such as high heating efficiency and uniform heating, generating a large amount of heat in a short time, thereby improving drying efficiency.
[0042] In this embodiment, the baking lamp 2110 is arranged along the drying channel 2100 with an arched cross-section and moves within the drying channel 2100 via a circular rail sliding assembly 2120. Its function is to heat and dry the train components, causing the surface moisture to evaporate and achieving the drying purpose. By moving the baking lamp 2110, uniform heating of different parts of the components can be achieved, avoiding localized overheating or insufficient drying, thus improving drying quality. The effect is that the position of the baking lamp 2110 can be flexibly adjusted according to the shape and size of the components, ensuring that the components receive comprehensive and uniform heating during the drying process, improving drying efficiency and quality.
[0043] like Figures 2 to 6 As shown, in this embodiment, the circular rail sliding assembly 2120 includes a circular arc slide rail 2121. A track groove 2200 corresponding to the circular arc slide rail 2121 is provided in the drying oven 2000. The two ends of the circular arc slide rail 2121 are fixedly connected in the track groove 2200. A plurality of track teeth 2122 and sliding components 2123 that mesh with the track teeth 2122 are provided on the circular arc slide rail 2121.
[0044] The sliding component 2123 includes a sliding block 2124, which has a sliding groove 2125 that accommodates at least part of the arc-shaped slide rail 2121. A drive gear 2127 that meshes with the track teeth 2122 is connected to the sliding block 2124. A rotating shaft 2128 is provided on the drive gear 2127 and a drive motor 2129 is connected to it. The drive motor 2129 is fixedly connected to the sliding block 2124.
[0045] Among them, the arc slide rail 2121 is set to an arc shape on one side of the sliding groove 2125, the sliding groove 2125 is set with a cross section corresponding to the arc slide rail 2121, and the cross section of the sliding groove 2125 is set to a "U" shape.
[0046] Specifically, the circular rail sliding assembly 2120 is a key component for enabling the baking lamp 2110 to move in the drying channel 2100, and mainly consists of a circular arc slide rail 2121, a track groove 2200, a track tooth 2122, and a sliding component 2123.
[0047] In this embodiment, the arc-shaped slide rail 2121 is the track for the movement of the baking lamp 2110. Its shape matches the arched cross-section of the drying channel 2100, and it is typically made of a high-strength, wear-resistant metal material, such as stainless steel. One side of the arc-shaped slide rail 2121 corresponding to the sliding groove 2125 is set in an arc shape. This design allows for better cooperation with the sliding groove 2125 of the sliding component 2123, reducing friction during sliding and improving the smoothness of the sliding process.
[0048] In this embodiment, the track groove 2200 is disposed inside the drying chamber 2000 for fixing the arc slide rail 2121. The shape and size of the track groove 2200 are adapted to the arc slide rail 2121, which can ensure that the arc slide rail 2121 is stably installed in the track groove 2200 without shaking or shifting.
[0049] In this embodiment, the track teeth 2122 are disposed on the arc slide rail 2121 and mesh with the drive gear 2127 of the sliding component 2123. The tooth profile and dimensions of the track teeth 2122 are precisely machined according to the design requirements of the drive gear 2127 to ensure that the two can mesh tightly and achieve stable transmission.
[0050] In this embodiment, the sliding block 2124 is provided with a sliding groove 2125 that accommodates at least a portion of the arc-shaped slide rail 2121. The cross-section of the sliding groove 2125 is U-shaped, matching the arc-shaped side surface of the arc-shaped slide rail 2121, enabling the sliding block 2124 to slide smoothly on the arc-shaped slide rail 2121. The drive gear 2127 meshes with the track teeth 2122. Driven by the drive motor 2129, the drive gear 2127 rotates on the track teeth 2122, thereby realizing the movement of the sliding block 2124 on the arc-shaped slide rail 2121. The drive motor 2129 is the power source of the sliding component 2123. It is connected to the drive gear 2127 through the rotating shaft 2128, providing power for the rotation of the drive gear 2127. The drive motor 2129 is fixedly connected to the sliding block 2124, ensuring that the drive motor 2129 and the sliding block 2124 move synchronously. The rotating shaft 2128 connects the drive gear 2127 and the drive motor 2129. The function of the rotating shaft 2128 is to transmit the power of the drive motor 2129 to the drive gear 2127, while ensuring that the drive gear 2127 can rotate stably.
[0051] like Figures 5 to 7 As shown, in this embodiment, a first positioning block 2130 is provided at one end of the drive motor 2129, a second positioning block 2131 is provided at the end of the drive gear 2127 away from the drive motor 2129, a fixing plate 2126 is provided at the end of the sliding block 2124 away from the drive motor 2129, and a rotating shaft 2128 passes through and is rotatably connected to the fixing plate 2126.
[0052] The track groove 2200 is provided with a first positioning groove 2210 corresponding to the first positioning block 2130 and a second positioning groove 2220 corresponding to the second positioning block 2131. When the sliding component 2123 moves on the arc slide rail 2121, the first positioning block 2130 and the second positioning block 2131 are respectively located in the first positioning groove 2210 and the second positioning groove 2220, which play a role in positioning and guiding, ensuring that the sliding component 2123 moves accurately along the arc slide rail 2121.
[0053] In this embodiment, the fixing plate 2126 is located at the end of the sliding block 2124 away from the drive motor 2129, and the rotating shaft 2128 passes through and is rotatably connected to the fixing plate 2126. The function of the fixing plate 2126 is to provide support for the rotating shaft 2128 and ensure the stability of the rotating shaft 2128 during rotation.
[0054] In this embodiment, the function of the circular rail sliding assembly 2120 is to drive the baking lamp 2110 to move along the arch-shaped cross-section in the drying channel 2100, so that the baking lamp 2110 can uniformly heat different parts of the train components. The effect is that through precise mechanical design and transmission system, the baking lamp 2110 moves smoothly and accurately, improving the uniformity and efficiency of drying, while reducing the workload of manual operation and increasing the degree of production automation.
[0055] like Figures 1 to 3 As shown, in this embodiment, a closed door 2134 is provided at both ends of the drying channel 2100, a drying fan 2132 is provided at the bottom of the drying channel 2100, and a waste gas recovery port 2133 connected to the waste gas recovery device 2400 is provided at the top of the drying channel 2100. The waste gas recovery device 2400 is connected to a waste gas recovery pipe 2410.
[0056] In this embodiment, the drying fan 2132 is located at the bottom of the drying channel 2100, and is typically a centrifugal fan or an axial fan. Centrifugal fans are characterized by large air volume and high air pressure, enabling them to blow hot air at high speeds toward the train components, thus improving drying efficiency. Axial fans, on the other hand, have the advantages of simple structure and low cost, making them suitable for applications where air volume and air pressure requirements are not particularly high.
[0057] In this embodiment, the function of the drying fan 2132 is to deliver hot air into the drying channel 2100 to accelerate the evaporation of moisture from the surface of the train parts. The hot air forms a circulating airflow within the drying channel 2100, which enables a more uniform heat distribution on the surface of the parts, further improving the drying effect. The effect is that through reasonable fan selection and arrangement, sufficient airflow and air pressure are ensured within the drying channel 2100, effectively transferring heat to the surface of the parts, shortening the drying time, and improving the drying quality.
[0058] In this embodiment, the exhaust gas recovery port 2133 is located at the top of the drying channel 2100 and is used to draw the exhaust gas generated during the drying process into the exhaust gas recovery device 2400. The design of the exhaust gas recovery port 2133 should ensure that it can fully collect the exhaust gas in the drying channel 2100 and prevent the exhaust gas from leaking into the external environment.
[0059] In this embodiment, the function of the waste gas recovery device 2400 is to collect the waste gas generated during the drying process through the waste gas recovery port 2133, reduce the pollution of the environment by the waste gas, and transmit the waste gas to the waste gas treatment equipment through the waste gas recovery pipe 2410.
[0060] In this embodiment, the waste gas recovery pipe 2410 connects the waste gas recovery device 2400 and the waste gas treatment equipment, transporting the collected waste gas to the waste gas treatment equipment for processing. The waste gas recovery pipe 2410 is typically made of corrosion-resistant and high-temperature-resistant materials, such as stainless steel, to ensure that no leakage or damage occurs during the transportation of waste gas.
[0061] In this embodiment, the waste gas treatment equipment is used to purify the collected waste gas, removing harmful substances and odors. The waste gas treatment equipment can employ various treatment processes such as activated carbon adsorption, catalytic combustion, and spray towers, selected according to the composition of the waste gas and emission requirements.
[0062] Specifically, sealing doors 2134 are located at both ends of the drying channel 2100, and are typically opened automatically or manually. The function of sealing doors 2134 is to isolate the drying channel 2100 from the external environment during the drying process, preventing heat loss and the entry of external dust and debris into the drying channel 2100, which could affect the drying effect and the quality of the parts. When train parts need to enter or leave the drying channel 2100, sealing doors 2134 open automatically or manually, and close automatically after the parts have passed through. This ensures the airtightness of the drying channel 2100, improves drying efficiency and quality, and reduces interference from the external environment during the drying process.
[0063] This utility model has many application scenarios, including but not limited to the following:
[0064] In the context of large-scale production of high-speed train components, a large number of parts need to be dried. This drying device is equipped with a conveyor belt, which enables continuous conveying and drying of components, meeting the high-efficiency requirements of large-scale production. Components are sequentially fed into the drying chamber via the conveyor belt, and then uniformly dried in the drying channel before being output, greatly improving production efficiency. It is suitable for use in high-speed train component production workshops with fast production cycles and large output.
[0065] For high-speed train components with extremely high drying quality requirements, such as precision mechanical parts and electronic components, ordinary drying equipment may not be able to meet the need for uniform drying. However, this drying device, through its arched drying channel and movable baking lamp design, can ensure that all parts of the components are dried evenly and thoroughly, guaranteeing the performance and quality of the components. Therefore, it is suitable for processing scenarios with strict requirements for drying quality.
[0066] With increasing environmental awareness, more and more high-speed train component manufacturers are beginning to prioritize environmental protection in their production processes. This drying unit is equipped with a waste gas recovery system, which effectively collects and treats waste gas generated during the drying process, reducing environmental pollution. For companies that value their environmental image and actively fulfill their social responsibilities, this environmentally friendly drying unit is an ideal choice, helping them achieve green production and enhancing their social image and market competitiveness.
