Embodiment 1

[0029] An oil tank with cleaning and sewage discharge function, comprising an oil tank body 1, an oil tank cover 9, an oil supply interface 20 and an oil return interface 21, the oil tank cover 9 and the oil return interface 21 are arranged on the top of the oil tank body 1, and the oil supply interface 20 is arranged on the oil tank The lower part of the body; the fuel tank cover 9 is connected with a filter cup 11, and a boss 10 is provided between the fuel tank cover and the fuel tank body, and the boss raises the height of the manual fuel filler; the bottom of the fuel tank body adopts a tapered design, and the sewage outlet interface 14 is arranged at the lowest point of the conical bottom; the top of the fuel tank body is provided with a cleaning interface 7, which communicates with the microporous nozzle 8, and the microporous nozzle is arranged inside the fuel tank body, and the pipe wall of the microporous nozzle 8 Set up microwells.

Embodiment 2

[0037] On the basis of Example 1, a preferred solution is proposed. The fuel tank body is designed as a cuboid structure, and the micropore nozzle is arranged at the geometric center of the fuel tank to ensure that the range of fuel or cleaning agent injected in the micropore can cover the side wall of the fuel tank and The bottom surface and the upper part of the fuel tank are equipped with a 0.1-1MP safety valve. When the liquid level in the fuel tank reaches the set lower limit, the liquid level sensor will send out a low oil level alarm signal. At this time, an external oil pump is required to automatically refill or manually refill diesel oil. Inserting the engine oil return conduit under the fuel liquid level can effectively prevent air from entering the engine and improve the engine start performance after a long shutdown.

[0038] The working principle of the present invention:

[0039] A fuel tank with cleaning and sewage function. Injecting a certain pressure of fue...

Abstract

The invention relates to an oil tank with the cleaning and contamination draining function. The oil tank comprises an oil tank body, an oil tank cover, an oil supply port and an oil return port, wherein the oil tank cover and the oil return port are designed at and in the top of the oil tank body; the oil supply port is formed in the lower portion of the oil tank body; the bottom of the oil tank body is in a tapered design, and a contamination draining port is formed in the lowest position of the tapered bottom; a cleaning port is formed in the top of the oil tank body and communicates with amicro-hole spray pipe; the micro-hole spray pipe is disposed in the oil tank body; and micro holes are formed in the pipe wall of the micro-hole spray pipe. Cleaning and contamination draining can beperformed on the interior of the oil tank without disassembling the oil tank, the cleanliness of fuel oil is guaranteed, functions such as overvoltage protection, contamination draining, fuel oil filtering, capability of preventing air from flowing into an oil return pipeline and automatic refueling are achieved, and the advantages that cleaning operation is simple and convenient, contamination draining is thorough, and the corrosion resistance is high are achieved.

Description

technical field [0001] The invention relates to the field of engine oil supply systems, in particular to an oil tank with cleaning and sewage discharge functions. Background technique [0002] At present, there are few domestic studies on the automatic cleaning function of the fuel tank of the engine fuel supply system. The cleaning measures for the fuel tank are mostly disassembled and then cleaned, and then the fuel tank is assembled. This method is cumbersome to operate. Fuel tanks that are difficult to disassemble are not suitable, and the cleaning effect with simple tools is not ideal. Generally, the engine oil return interface of the fuel tank is directly connected to the fuel tank. When the engine is shut down for a long time, the air in the fuel tank will escape into the engine through the oil return line, causing the engine to fail to start and affecting the engine's starting performance. With the increase of working time, the impurities in the fuel tank will conti...
