Description

Technical Field

[0001] The present invention relates to the technical field of oil-water separation, and particularly to an oil-water separation device for a flatbed vehicle. Background Art

[0002] Oil-water separation mainly relies on the density difference or different chemical properties of water and oil, and uses the principle of gravity sedimentation or other physical and chemical reactions to remove impurities or complete the separation of oil and water; the flatbed vehicle is one of the shipbuilding equipment. After years of use, it has gradually revealed the problem of a relatively high failure frequency of the vehicle's pneumatic control system. Some pneumatic control components are repeatedly damaged and repaired, which not only affects production and increases maintenance costs, but also poses certain safety hazards because the pneumatic control system controls the braking of the whole vehicle. The pneumatic control system of the flatbed vehicle is relatively complex, and the main control valve parts are all imported and relatively expensive. The system consists of precision valve parts such as air compressors, electro-hydraulic proportional valves, and brake valves, as well as a series of pneumatic actuators. Due to the particularity of the gas medium, once a fault occurs in the system, the internal components are extremely likely to be damaged one by one, and it is extremely difficult to find the source of the problem; After disassembly, it was determined that there was water stain at the gas pipeline near the control component away from the air source component, there was oil stain at the joints of some control components, and the valve bodies of some valve parts were made of aluminum alloy and were prone to corrosion and expansion. Therefore, it was judged that a series of faults occurred due to the irregular accumulation of excessive water and oil content in the gas circuit. After observation, the drying barrel was working normally and the dryness of the nearby pipeline was relatively high, but the oil-water filter separator in the pipeline did not play a key fine filtering role. Mainly because the oil stain collected in the oil-water separator during actual use could not be discharged in time, resulting in excessive accumulation of internal oil stain and impurities, thereby reducing its separation effect. Summary of the Invention

[0003] The purpose of the present invention is to solve or at least alleviate the problems existing in the prior art.

[0004] To achieve the above purpose, the present invention provides the following technical solution: an oil-water separation device for a flatbed vehicle, including a housing, a connection component is installed on the outer wall of the top of the housing, a sewage discharge port is opened on the outer wall of the bottom of the housing, and a sewage discharge mechanism is installed on the inner wall of the sewage discharge port.

[0034] Embodiment 2 Based on Embodiment 1, this embodiment introduces the specific structure of the driving component 20 in an oil-water separation device for a flatbed vehicle. Figures 8-9 As shown, a driving member 34 is installed on the inner wall of the connecting frame 27. The driving member 34 includes a driving tube 35 fixedly connected to the connecting frame 27.

[0035] Working principle: During use, the gas in the pore system enters the outer shell 1 through the intake pipe 3, is transported to the installation pipe 9 through the through holes 13 on the trachea 12, and then enters the outer shell 1 after the gas passes through the filter screen 10. After passing through the separation layer 8, the gas is directly discharged through the exhaust cavity 15 and the exhaust pipe 4. When it is necessary to discharge the oil and water in the outer shell 1, the driving assembly 20 drives the first sealing plug 23 to move downward to open the sewage outlet. When the first sealing plug 23 moves downward, it directly drives the second sealing plug 25 to move downward to close the material opening at the bottom of the sewage pipe 18. At this time, the oil and water in the outer shell 1 will enter the sewage pipe 18. When discharging the oil and water, the first sealing plug 23 moves upward and the second sealing plug 25 moves upward at the same time, so as to facilitate the direct discharge of the oil and water in the sewage pipe 18. In the driving assembly 20, the micro motor 39 directly drives the driving disc 40 to rotate under the control of the controller's rotation speed. When the driving disc 40 rotates, it cooperates with the connecting rod 33 to pull the second sliding seat 32 to reciprocate up and down. The setting of the fixed connecting rod facilitates the synchronous movement of the second sliding seat 32 and the first sliding seat 31, so it is convenient for the two sealing plugs to move. Or the electromagnet 38 is energized to generate magnetism and directly attracts the armature 37 to move towards the electromagnet 38, thereby facilitating the direct pulling of the driving column 36 and the second sliding seat to move downward. When the second sliding seat 32 moves downward, it directly compresses the first spring 29 and the second spring 30.
