Description

Technical Field

[0001] This application relates to the field of rail vehicle technology, specifically to a waste bin for high-speed trains with a plastic coating. Background Technology

[0002] Currently, high-speed trains use waste bins, which are containers that collect and discharge passengers' urine and feces through special equipment. Due to their special corrosiveness, these waste bins require highly corrosion-resistant materials, typically 316 or 316L stainless steel. This results in high manufacturing costs, both in terms of materials and processing. Furthermore, defects in materials or processing can easily lead to leaks and contaminate the sealed environment under the train.

[0003] Therefore, to meet practical needs, a waste bin for high-speed trains with a dip-coated layer is provided. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the purpose of this application is to provide a waste bin for high-speed trains with a dip-coated layer. Through a specific dip-coated layer, the internal structure of the waste bin is protected, and costs are effectively controlled while ensuring usage requirements are met.

[0008] Waste bin functional components are installed on the inner wall of the main body of the waste bin;

[0009] A dip-coating layer is disposed inside the main body of the waste bin, the dip-coating layer covering the inner wall of the main body of the waste bin, the surface of the functional components of the waste bin, and the interfaces of the waste inlet, the waste outlet, the exhaust outlet, and the cleaning outlet located inside the main body of the waste bin.

[0010] Based on the above technical solution, the functional components of the waste tank include a liquid level detector and a heating tube.

[0017] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0019] This application provides a waste bin for high-speed trains with a dip-coated layer. The specific dip-coated layer protects the internal structure of the waste bin, effectively controlling costs while ensuring usage requirements are met.

[0020] To achieve the aforementioned technical effects, the overall concept of this application is as follows:

[0021] A waste bin for high-speed trains with a dip-coated layer, the waste bin comprising:

[0022] The main body of the waste bin 1 is provided with a waste inlet 10, a waste outlet 11, a vent 12 and a cleaning outlet 13.

[0023] Waste bin functional component 2 is disposed on the inner wall of the waste bin body 1;

[0024] The plastic coating layer 3 is disposed inside the main body 1 of the waste bin. The plastic coating layer 3 covers the inner wall of the main body 1 of the waste bin, the surface of the functional component 2 of the waste bin, and the interfaces of the inlet 10, the outlet 11, the exhaust 12, and the cleaning port 13 located inside the main body 1 of the waste bin.

[0025] The embodiments of this application will be further described in detail below with reference to the accompanying drawings.

[0026] See Figure 1 As shown in the figure, this application embodiment provides a train waste bin with a dip-coated layer, the train waste bin comprising:

[0027] The main body of the waste bin 1 is provided with a waste inlet 10, a waste outlet 11, a vent 12 and a cleaning outlet 13.

[0028] Waste bin functional component 2 is disposed on the inner wall of the waste bin body 1;

[0029] The plastic coating layer 3 is disposed inside the main body 1 of the waste bin. The plastic coating layer 3 covers the inner wall of the main body 1 of the waste bin, the surface of the functional component 2 of the waste bin, and the interfaces of the inlet 10, the outlet 11, the exhaust 12, and the cleaning port 13 located inside the main body 1 of the waste bin.

[0030] The technical solution of this application embodiment, based on the original stainless steel frame, uses dip-coating technology to attach a layer of highly corrosion-resistant and highly adhesive plastic to the inside of the stainless steel welded assembly and the outer surface of the internal welded parts. This improves the corrosion resistance of the stainless steel welded waste bin. If appropriate, the stainless steel material can also be reduced from 316L to other materials with relatively lower cost and weaker corrosion resistance, solving the problems of high material cost and poor substitutability. Widespread application can save economic costs.

[0031] In this embodiment, a specific dip-coating layer is used to protect the internal structure of the waste bin, effectively controlling costs while ensuring usage requirements are met.

[0032] Furthermore, the waste tank functional component 2 includes a liquid level detector and a heating tube.

[0033] The technical solution based on the embodiments of this application is as follows:

[0034] The waste bin for high-speed trains with a dip-coated layer consists of three parts: the main body of the waste bin 1, the functional components of the waste bin 2, and the dip-coated layer 3.

[0035] Furthermore, the main body 1 of the waste bin, including waste bins of any form and shape, should be designed to avoid sharp edges and corners after welding. It should also meet the requirements for dip coating after welding.

[0036] Furthermore, the dip-coated layer 3 is made of a plastic material with strong resistance to dirt and corrosion and excellent adhesion, and uses a dip-coating process. It also has a certain resistance to negative pressure, ensuring it can maintain its full service life without peeling or detaching under specified negative pressure.

[0037] Furthermore, for the waste tank functional components 2, such as the level indicator detector and heating tube, appropriate interfaces are selected during the dip-coating process so that the product's functionality is not affected after installation.

[0038] In summary, the technical solution of this application embodiment has the following advantages:

[0039] (1) Use dip coating process to improve the corrosion resistance of the waste bin.

[0040] (2) Reduce the material and process costs of welding stainless steel, improve the limitations and substitutability of materials, and reduce manufacturing and maintenance costs.
