Description

Technical Field

[0001] This invention relates to the field of specialty industrial oil treatment technology, specifically to a special industrial oil life-extending filter washing and replacement device. Background Technology

[0002] Specialty oils mainly refer to hydraulic oils, refrigeration oils, hydraulic transmission oils, and gear oils that are widely used in industries such as metallurgy, machinery, mining, transportation, and manufacturing.

[0003] After use, specialty oils contain water, gases, light hydrocarbons, organic and inorganic acids, as well as acidic oxidizing particles and sludge, resulting in decreased lubrication performance. Filtering and reprocessing cleaning oils and specialty oils allows for recycling and reuse, extending their lifespan and making them more environmentally friendly.

[0004] The storage tank in the filter washing and replacement device for special oil recycling is generally equipped with a heating structure, which can disperse the water in the oil and achieve oil-water separation. Because the storage tank is large, the heating speed will be slow. Moreover, the oil is inside the tank, and the contact area between the liquid surface and the air is small, resulting in a small water vapor dispersion area, which slows down the oil-water separation speed. Summary of the Invention

[0005] The purpose of this invention is to provide a special industrial oil life-extending filter washing and replacement device to solve the problems mentioned in the background art, such as the large size of the storage tank, which slows down the heating speed, and the small contact area between the oil surface and the air and the small water vapor dispersion area inside the tank, which leads to slow oil-water separation speed.

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0033] Example:

[0034] Please see Figures 1-5 This invention provides a special industrial oil life-extending filter washing and replacement device, including an oil inlet, which is connected to a storage tank 1 via a pipeline. An electric pump is installed on the pipeline connecting the oil inlet and the storage tank 1. An overflow valve is installed on the pipeline between the oil inlet and the storage tank 1 at the location of the electric pump. A filling port is provided on the outside of the storage tank 1, which is connected to the storage tank 1 and a vacuum dehydrator via a pipeline. The oil inlet, the storage tank 1, and the vacuum dehydrator are connected via a pipeline. An air pump is installed on the storage tank 1 via a pipeline. A coarse filter is installed on the vacuum dehydrator via a pipeline. A microparticle amplifier is installed on the coarse filter via a pipeline. A medium filter is installed on the microparticle amplifier via a pipeline. An adsorption fine filter is installed on the medium filter via a pipeline. A nano-membrane filter is installed on the adsorption fine filter via a pipeline. The nano-membrane filter is connected to an oil outlet via a pipeline. A floating heating device 2 is installed floatingly inside the storage tank 1. A circulating oil spraying device 3 is provided on the outside of the floating heating device 2. The circulating oil spraying device 3 is fixedly connected to the top of the storage tank 1.

[0035] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the floating heating device 2 includes a float 201, a spiral metal tube 202, a heating core 203, a hollow tube 204, and a wire 205. The spiral metal tube 202 is fixedly installed on the lower side of the float 201. The heating core 203 is built into the spiral metal tube 202. The hollow tube 204 is fixedly installed at the end of the spiral metal tube 202. The hollow tube 204 passes through the float 201. A perforation is opened at the top of the storage tank 1, through which the hollow tube 204 passes. The wire 205, which is electrically connected to the heating core 203, is provided inside the hollow tube 204. The floating heating device 2 can float with the oil, and the spiral metal tube 202 is in the oil, so it is heated from inside the oil.

[0036] Specifically, such as Figure 1 , Figure 2 and Figure 4As shown, a side block 208 is fixedly installed at the edge of the float 201, and a circulating oil injection device 3 is fixedly installed at the position of the side block 208. The circulating oil injection device 3 includes an insert pipe 301, a circulating U-shaped bend 302, a circulating pump 303, a spray ring 304, a flexible metal pipe 305, and a counterweight oil suction ball 306. A through hole is opened on the float 201, and the insert pipe 301 is installed above the through hole. The circulating U-shaped bend 302 is sleeved on the insert pipe 301. The bend of the circulating U-shaped bend 302 is fixed at the top of the storage tank 1. The circulating pump 303 is installed on the part of the circulating U-shaped bend 302 above the storage tank 1. The outlet of pump 303 is located inside storage tank 1. The outlet ends of all circulating U-shaped bends 302 are connected to spray ring 304. Spray ring 304 is sleeved on the outside of floating heating device 2. Spray holes are opened at the bottom of spray ring 304. Spray ring 304 is located above float 201. Flexible metal pipe 305 is connected to the bottom of the through hole of float 201. The end of flexible metal pipe 305 is connected to counterweight oil suction ball 306. The circulating oil spraying device 3 rises with floating heating device 2 and sprays oil in a circulating manner to increase the contact area between oil and air and accelerate the dissipation of water in oil.

[0037] Specifically, such as Figure 1 As shown, the bottom edge of the float plate 201 is an annular plane. The bottom of the float plate 201 is obliquely convex outward on the inner side of the annular plane. An annular groove 206 is opened on the float plate 201 at the annular plane position. The spiral metal tube 202 is fixed at the position of the annular groove 206 to maintain the stability of the float plate 201 floating on the oil.

[0038] Specifically, such as Figure 1 As shown, the top of the float plate 201 is obliquely concave, and the oil outlet 207 is opened at the center of the float plate 201, so that the oil on the float plate 201 can slide down and fall from the oil outlet 207.

[0039] Specifically, such as Figure 2 As shown, a limiting ring 209 is provided at the top of the hollow tube 204. The top of the storage tank 1 is fixedly installed below the perforation, and the hollow tube 204 is installed through the conduit 4 to prevent the hollow tube 204 from separating from the conduit 4.

[0040] Working principle:

[0041] After the oil enters the storage tank 1, the float plate 201 rises with the rise of the oil level, the hollow tube 204 moves up and down along the guide tube 4, and the limiting ring 209 has the function of limiting the downward movement of the hollow tube 204. The spiral metal tube 202 is located inside the oil. After the power is turned on, the wire 205 is electrically connected to the heating core 203. The heating core 203 heats up, the spiral metal tube 202 is heated, and the heat is transferred to the inside of the oil, thereby heating the inside of the oil. Combined with the original heating device of the storage tank 1, the storage tank 1 can heat the oil from the side and inside at the same time, which increases the heating rate of the oil and speeds up the oil-water separation.

[0042] Meanwhile, as the float 201 floats with the oil, the insertion tube 301 moves along the circulation U-shaped bend 302 within the circulation U-shaped bend 302. The insertion tube 301 always maintains the circulation U-shaped bend 302 in a connected state. The counterweight oil suction ball 306 is in contact with the bottom of the storage tank 1. When the oil is heated, the circulation pump 303 draws the oil from the counterweight oil suction ball 306 to the flexible metal tube 305, from the flexible metal tube 305 to the insertion tube 301, from the insertion tube 301 to the circulation U-shaped bend 302, and from the circulation U-shaped bend 302 to the spray ring 304. Then the oil is sprayed out from the spray ring 304. This heated oil spray state increases the contact area between the oil and the air, accelerates the evaporation of water in the oil, and speeds up the oil-water separation.

[0043] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
