Description

Technical Field

[0001] The invention relates to oil filling, and in particular to an oil filling device with a high-pressure resistant and explosion-proof structure. Background Art

[0002] Oil filling is an important part of oil production. The method and device of oil filling will affect the quality after filling. At present, oil filling mostly adopts the following two methods: 1. Manual operation, which is cumbersome and has bubbles, causing serious waste and dirt. 2. Conventional air pressure type, which is unstable, uneven oil output, bubbles, and sometimes even sprays out oil pressure; the oil filling port is not tightly connected, and the oil filling pipe is easy to fall off, causing waste and dirt; special oil - such as oil that is too viscous and has poor fluidity and cannot be used.

[0003] In summary, it is necessary to improve the high pressure resistance of the oil filling device and increase the pressure difference, so that it can be used for oil with poor fluidity and can compact the oil to prevent the generation of bubbles. Summary of the invention

[0004] In view of this, the present invention provides an oil filling device with a high-pressure explosion-proof structure, which improves the oil filling efficiency and eliminates bubbles in the oil compared to the prior art, while improving the high-pressure explosion-proof performance of the tank body, making it suitable for filling different types of oils.

[0005] To this end, the present invention provides an oil filling device with a high-pressure explosion-proof structure. First, a tank body is set, which includes an outer tank and an inner tank. The inner tank is fixedly installed on the bottom of the outer tank, and a first pressure-resistant cover is detachably installed on the top of the outer tank. A second pressure-resistant cover is movably installed on the top of the inner tank. Oil is arranged in the inner tank, and the second pressure-resistant cover presses the oil. The boosting mechanism includes an air pipe, an air pump and a pressure gauge. One end of the air pipe passes through the first pressure-resistant cover and is positioned in the outer tank, and the other end of the air pipe is connected to the air pump. The pressure gauge is installed on the air pipe. The oil supply mechanism includes an oil supply pipe and an oil supply joint. The first end of the oil supply pipe passes through the first pressure-resistant cover and the second pressure-resistant cover in sequence and is positioned in the oil. The second end of the oil supply pipe is connected to the oil supply joint, and the oil supply joint is connected to an oil storage bottle.

[0006] Furthermore, a sealing component is detachably mounted at the connection between the first pressure-resistant cover and the outer tank.

[0007] Furthermore, the sealing component is a clamp.

[0008] Further, the clamp includes a first half ring and a second half ring, the first end of the first half ring is hinged to the first end of the second half ring, and the second end of the first half ring is detachably connected to the second end of the second half ring.

[0009] Furthermore, a spacing adjustment component is directly connected between the second end of the first half ring and the second end of the second half ring.

[0010] Furthermore, the spacing adjustment component includes a screw-on handle and a screw-on ball, the screw-on handle is fixedly mounted on the second end of the first half ring, the screw-on ball is fixedly mounted on the second end of the second half ring, and the screw-on handle is screwed to the screw-on ball.

[0011] Furthermore, an oil supply valve is installed on the top of the oil pipe.

[0012] Furthermore, a through hole is provided on the first pressure-resistant cover, a quick-connect sleeve is installed in the through hole, and the air pipe is passed through the quick-connect sleeve.

[0014] Furthermore, the material of the outer tank is SUS304 stainless steel.

[0015] The present invention provides an oil filling device with a high-pressure resistant and explosion-proof structure, which is mainly provided with a tank body, a boosting mechanism and an oil supply mechanism. The tank body includes an outer tank and an inner tank, and a cavity is formed between the outer tank and the inner tank. The boosting mechanism injects air into the cavity to increase the air pressure in the cavity. A second pressure-resistant cover is movably installed on the top of the inner tank. The second pressure-resistant cover moves toward the bottom of the inner tank under the pressure of the air pressure in the cavity. At this time, the oil in the inner tank is forced out of the inner tank by the second pressure-resistant cover, and the oil flows to the outside along the oil supply mechanism penetrated in the inner tank until it flows into the oil storage bottle at the end of the oil supply mechanism, thereby completing the filling of the oil.

[0016] The present invention is different from ordinary pneumatic filling devices in the following aspects: 1. The outer tank body is made of SUS304 stainless steel, which can withstand higher air pressure and is corrosion-resistant; 2. An explosion-proof valve is provided. When the air pressure is too high, the explosion-proof valve releases pressure and does not cause oil spraying; 3.

[0024] 7. The air pipe is directly inserted into the outer tank through the quick-connect sleeve, which is portable and efficient. BRIEF DESCRIPTION OF THE DRAWINGS
