Description
Technical Field
[0001] This utility model belongs to the field of separation device technology, and in particular relates to an oil-water separation device for an air braking system used for safety control of railway locomotives. Background Technology
[0002] The oil-water separator is responsible for separating oil and water in the air. Before oil-water separation, large particulate impurities such as dust and dirt in the air need to be filtered by the filter plates installed inside the oil-water separator.
[0003] For example, Chinese patent CN206881372U discloses a compressed air oil-water separation filter device, which can not only extend the service life of the activated carbon in the filter device, but also achieve better oil-water separation effect.
[0004] In the aforementioned patent, since both the upper and lower screens are installed inside the gas tank, it is inconvenient to disassemble and clean the upper and lower screens when their filtration effect decreases after long-term use, thus reducing the ease of disassembly of the device.

[0034] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.
[0035] like Figure 2 and Figure 4 As shown, this embodiment provides an oil-water separation device for an air braking system used for railway locomotive safety control, including: a connecting frame 100, a filter plate 200, several pressing components 300, several elastic components 400, and an oil-water separator 500.
[0036] The oil-water separator 500 is used for separating oil and water in the air; the connecting frame 100 is used to connect the oil-water separator 500. The edge of the connecting frame 100 has several connecting holes. By passing bolts through the connecting holes and tightening the bolts, the connection and installation between the connecting frame 100 and the oil-water separator 500 is completed. The connecting frame 100 is hollow inside; the filter plate 200 is used to filter impurities in the air. The surface of the filter plate 200 has several small filter holes. The filter holes can perform preliminary filtration of impurities in the air to facilitate oil-water separation in the subsequent oil-water separation structure of the railway locomotive air braking system. The filter plate 200 is installed in the hollow structure of the connecting frame 100 by means of several elastic components 400.
[0037] Several elastic components 400 are installed inside the filter plate 200, and the filter plate 200 is limited and installed into the connecting frame 100 by elasticity (the specific limiting method is detailed below), thereby realizing the quick installation of the filter plate 200; several pressing components 300 are installed inside the connecting frame 100, and the elastic components 400 are pushed by external pressing to release the limiting of the filter plate 200, thereby realizing the quick disassembly of the filter plate 200, which facilitates the disassembly and cleaning of the filter plate 200.
[0038] like Figure 3 and Figure 6 As shown, the inner wall of the connecting frame 100 has two first grooves 110, which are elongated and are used to accommodate two elastic components 400. When the two elastic components 400 enter the interior of the two first grooves 110 with the help of elasticity, the two elastic components 400 can complete the limiting installation of the filter plate 200. The interior of the connecting frame 100 has two second grooves 120, which are square. The plurality of pressing components 300 are installed in the plurality of second grooves 120.
[0039] like Figure 4 As shown, the filter plate 200 has two third grooves 210, which are convex in shape and located on the edge of the filter plate 200. The elastic components 400 are installed inside the third grooves 210.
[0040] like Figure 6 As shown, the pressing assembly 300 includes: a first rod 310, a first plate 320, and a first spring 330.
[0041] The first plate 320 is square and is disposed inside the second groove 120, fitting and slidingly connected to the second groove 120. The first plate 320 is fixed to the first rod 310 to synchronously control the position of the first rod 310. The first rod 310 is a long columnar rod that passes through the first plate 320 and is fixed to it. Both ends of the first rod 310 along its length pass through the connecting frame 100. Initially, the first rod 310 is not inside the first groove 110. When the first rod 310 is pressed by an external force, it will cause the first plate 320 to slide inside the second groove 120, and at the same time, the first rod 310 will enter the first groove 110 and interact with the spring. When the force component 400 contacts, the elastic component 400 is further compressed, causing the elastic component 400 to move out of the first groove 110. At this point, the filter plate 200 can be quickly removed. The first spring 330 is sleeved on the outer wall of the first rod 310 and is positioned on the first plate 320 near the filter plate 200. When the first rod 310 is pressed and the first plate 320 slides along the inside of the second groove 120, the first plate 320 will compress the first spring 330. After the filter plate 200 is removed, the external force stops pressing the first rod 310. At this time, the compressed first spring 330 will release the compression force, sequentially pushing the first plate 320 and the first rod 310 back to their initial state, ready for the next removal and use.
[0042] like Figure 7 As shown, the elastic component 400 includes: a third plate 410, a through hole 420, a second rod 430, and a second spring 440.
[0043] The second rod 430 is a long column and is fixed to the interior of the third groove 210, guiding the movement of the third plate 410 so that it can move along the length of the second rod 430. The through hole 420 is a long hole located inside the third plate 410. The second rod 430 is disposed within the through hole 420 and slidably connected to it, providing sufficient space for its movement within the third plate 410. The third plate 410 and the second spring 440 are fixed to one end near the pressing assembly 300. The third plate 410 is T-shaped. By using the T-shaped third plate 410 and the convex third groove 210, the movement range of the third plate 410 is limited within the third groove 210. Initially, the second spring 440 pushes a portion of the third plate 410 out of the third groove 210, and the second rod 430... The portion of the third plate 410 that extends out of the third groove 210 is inserted into the first groove 110. Through the cooperation of the third plate 410 and the first groove 110, the filter plate 200 is positioned and installed. In the pressed state, the first rod 310 pushes the portion of the third plate 410 that extends out of the third groove 210 back into the third groove 210. At this time, the limiting state of the filter plate 200 is released, and the filter plate 200 can be quickly removed for cleaning, improving the ease of disassembly and assembly of the filter plate 200. The second spring 440 is sleeved on the outer wall of the second rod 430. When the first rod 310 pushes the portion of the third plate 410 that extends out of the third groove 210 back into the third groove 210, the third plate 410 compresses the second spring 440 to store energy. When the third plate 410 loses external thrust, the compressed second spring 440 will push a portion of the third plate 410 out of the third groove 210 again.
[0044] As a preferred embodiment of the first rod 310, such as Figure 6 As shown, a second plate 321 is fixedly connected to one end of the first rod 310 away from the filter plate 200 along the length direction. The second plate 321 is disc-shaped and has a diameter larger than that of the first rod 310. By setting the second plate 321, the contact area when the first rod 310 is pressed from the outside can be increased, the local pressure of pressing can be reduced, and the comfort of pressing can be improved.
[0045] In a further preferred embodiment, the surface of the second plate 321 is provided with a number of grooves 322. By setting the number of grooves 322, the contact area can be further increased when the second plate 321 is pressed from the outside, making it less likely to slip and improving the stability of pressing.
[0046] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
