Description

Technical Field

[0001] This utility model relates to the field of oil-water separation technology, specifically to an oil-water separation device for flatbed trucks. Background Technology

[0002] Oil-water separation primarily relies on the density difference or chemical properties of water and oil, utilizing the principle of gravity sedimentation or other physicochemical reactions to remove impurities or separate oil and water. Flatbed trucks, being shipbuilding equipment, have revealed a high frequency of malfunctions in their pneumatic control systems after years of use. Repeated damage and repairs of some pneumatic control components not only affect production and increase maintenance costs, but also pose certain safety hazards, as the pneumatic control system controls the vehicle's braking. The flatbed truck's pneumatic control system is complex, and the main control valves are all imported and expensive. The system consists of an air compressor, electronically controlled proportional valves, brake valves, and other precision valves, as well as a series of pneumatic actuators. Due to the special nature of the gas medium, once a system malfunctions, internal components are easily damaged one after another, and the source of the problem is extremely difficult to pinpoint.

[0003] After disassembly, it was determined that there were water stains in the gas pipeline near the control elements, away from the gas source components; oil stains were found at some control element joints; and some valve bodies, made of aluminum alloy, were prone to corrosion and expansion. Therefore, it was determined that the irregular accumulation of excessive water and oil content in the gas pipeline led to a series of malfunctions. Observation showed that the drying tank was functioning normally and the nearby pipelines were relatively dry. However, the oil-water filter separator in the pipeline was not performing its crucial fine filtration function. This was mainly because, during actual use, the oil collected in the separator could not be discharged in time, leading to excessive accumulation of oil and impurities inside, thus reducing its separation efficiency. Utility Model Content

[0004] The purpose of this invention is to solve or at least alleviate the problems existing in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an oil-water separation device for a flatbed truck, comprising a housing, a connecting component installed on the top outer wall of the housing, a drain port opened on the bottom outer wall of the housing, a drain mechanism installed on the inner wall of the drain port, a separation component installed on the inner wall of the housing, an observation port opened on the outer wall of the housing, and tempered glass fixedly connected to the inner wall of the observation port;

The downward movement of slide block two directly compresses spring one and spring two.

[0026] Compared with the prior art, the beneficial effects of this utility model are:

[0028] This utility model incorporates a separation component within the outer casing. This component facilitates the separation of oil and water in the gas supplied to the casing. The relatively clean air after separation is directly discharged through the exhaust pipe, thereby enabling convenient separation and filtration of the gas in the vent system. The mesh on the mounting pipe facilitates the filtration of impurities in the air, preventing impurities from clogging the separation layer.

[0029] This invention incorporates a drive assembly in the drain pipe, which facilitates the control of two sealing plugs within the drain pipe.

[0049] Example 2

[0050] Based on Example 1, this example describes the specific structure of the drive assembly 20 in an oil-water separator for a flatbed truck. Figure 8-9 As shown, a driving component 34 is installed on the inner wall of the connecting frame 27, and the driving component 34 includes a driving tube 35 fixedly connected to the connecting frame 27. A driving column 36 is slidably connected to the inner wall of the driving tube 35, and one end of the driving column 36 is fixedly connected to the slide block 32. An electromagnet 38 is fixedly connected to the inner wall of the bottom of the driving tube 35, and an armature 37 matching the electromagnet 38 is fixedly connected to the outer wall of the bottom of the driving column 36.

The downward movement of the slide block 32 directly compresses the spring 29 and the spring 30.

[0051] Working principle: During use, the gas in the vent system enters the outer casing 1 through the inlet pipe 3, and is then transported to the mounting pipe 9 through the through hole 13 on the air pipe 12. After being filtered by the filter screen 10, the gas enters the outer casing 1. After being filtered by the separation layer 8, the gas passes through the exhaust chamber 15 and is directly discharged through the exhaust pipe 4. When it is necessary to discharge oil and water from the outer casing 1, the drive component 20 drives the sealing plug 23 to move down and open the drain port. When the sealing plug 23 moves down, it directly drives the sealing plug 25 to move down and close the bottom of the drain pipe 18. At this time, the oil and water in the outer casing 1 will enter the drain pipe 18. When releasing the oil and water, the sealing plug 23... As 23 moves upward, the second sealing plug 25 moves upward, thus facilitating the direct discharge of oil and water from the drain pipe 18. The micro motor 39 in the drive assembly 20 directly drives the drive disk 40 to rotate under the control of the controller. When the drive disk 40 rotates, it works with the connecting rod 33 to pull the slide 32 back and forth. When the fixed connecting rod is set, the slide 32 and the first slide 31 move synchronously. Therefore, when it is convenient, the two sealing plugs move, or the electromagnet 38 is energized and generates magnetism to directly attract the armature 37 to move towards the electromagnet 38, thus facilitating the direct pull of the drive column 36 to move the slide 32 downward. The downward movement of the slide 32 directly compresses the first spring 29 and the second spring 30.
