Description

Technical Field

[0001] This utility model relates to the field of heated oil tank technology, and in particular to a heated oil tank for an oil injector. Background Technology

[0002] Heated oil tanks for lubricators are core lubrication auxiliary components for equipment such as mining machinery, outdoor hydraulic equipment, and field operation motors. Their core function is to maintain the fluidity of lubricating oil in low-temperature environments through heating components, ensuring that the lubricator can stably deliver the lubricating medium to the friction pairs of the equipment and preventing equipment jamming, accelerated wear, and other malfunctions caused by oil solidification. However, the existing structural design of heated oil tanks still has many unresolved technical problems.

[0003] Existing heated oil tanks have an integrated welded structure consisting of the oil tank, heating element, and outer shell. When the heating element malfunctions, the entire oil tank needs to be disassembled. In addition, existing heated oil tanks mostly heat only one location, which can easily cause problems such as localized overheating and incomplete heating. Utility Model Content

[0004] The main objective of this invention is to provide a heated oil tank for an oil injector to solve the problems raised in related technologies.

[0005] To achieve the above objectives, according to one aspect of the present invention, a heated oil tank for an oil injector is provided, comprising: a heating part and an oil storage part, wherein the heating part includes a heating component, the oil storage part includes an oil storage component, a heat-conducting layer is provided on the outside of the oil storage component, the heat-conducting layer is provided inside the heating component, and is used to conduct the heat provided by the heating component and to keep the oil inside the oil storage component warm.

[0006] Furthermore, the heating assembly includes a first heating element, a bottom heating element, a second heating element, a first fixing hole, a second fixing hole, and a main body shell. The first heating element and the second heating element are respectively fixedly connected to two opposite inner walls of the main body shell, and the bottom heating element is fixedly connected to the bottom inner wall of the main body shell, for providing a heat source for the oil storage assembly.

[0007] Furthermore, the outer walls on both sides of the main body shell are respectively provided with a first fixing hole and a second fixing hole, and the positions of the first fixing hole and the second fixing hole are corresponding.

[0008] Furthermore, the oil storage assembly includes a guide channel, an oil storage tank, and a liquid level sensor. The guide channel is opened on the inner wall of the oil storage tank in a spiral upward shape to guide the flow of heated oil. An oil tank nozzle is fixedly installed in the upper central area of ​​the oil storage tank. The oil tank nozzle communicates with the inside of the oil storage tank. The outer wall of the oil tank nozzle is provided with external threads for installation with an oil injector.

[0009] Furthermore, an insulation cover is fixedly installed on the top of the main body shell, and a first fixing plate and a second fixing plate are fixedly connected to both ends of the insulation cover respectively. The first fixing plate has a first threaded hole, and the second fixing plate has a second threaded hole. The first fixing plate is threadedly connected to the main body shell through a first fixing bolt, and the second fixing plate is threadedly connected to the main body shell through a second fixing bolt.

[0010] Furthermore, an insulation layer is fixedly connected to the bottom of the insulation cover to insulate the heat inside and outside the oil storage tank.

[0011] Furthermore, a liquid level sensor is fixedly connected through the heat preservation cover, and the lower end of the liquid level sensor penetrates through the upper wall of the oil storage tank and extends into the cavity.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention, by setting a guide channel, allows the heated oil, which has a lower density than the cold oil, to exchange positions with the cold oil above after the heating component is activated. Under the action of the guide channel, the hot oil moves in an orderly manner inside the oil tank, forming a convection circulation within the cavity. Compared with traditional heated oil tanks, this greatly improves heating efficiency. On the other hand, the guide channel also reduces turbulent impact of the oil during the heating process, reducing the scouring and wear of the oil on the inner wall of the oil tank.

[0014] By incorporating a liquid level sensor, dry burning due to insufficient oil inside the chamber can be effectively prevented, extending the equipment's lifespan. Furthermore, the detachable, layered structure allows for the replacement of only the damaged components in case of equipment failure, eliminating the need for complete replacement. This also improves cleaning efficiency: when excessive oil buildup inside the chamber affects operation, the oil tank can be disassembled for thorough cleaning without concern for waterproofing the heating components, saving time and manpower.

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] This embodiment provides a heated oil tank for an oiler, such as... Figure 1 As shown, the system includes a heating section and an oil storage section. The heating section includes a heating element 9, and the oil storage section includes an oil storage element 7. A heat-conducting layer 10 is fitted over the oil storage element 7, inside the heating element 9. The heat-conducting layer 10 conducts the heat provided by the heating element 9 and insulates the oil inside the oil storage element 7. The height of both the heat-conducting layer 10 and the oil storage element 7 is lower than the internal depth of the heating element 9. The heat-conducting layer 10 efficiently transfers heat from the heating element 9 to the oil storage element 7 and reduces heat loss from the oil, ensuring the oil maintains a stable temperature in low-temperature environments and avoiding heat loss. The fact that the height of both the heat-conducting layer 10 and the oil storage element 7 is lower than the internal depth of the heating element 9 allows for better cooperation with the insulation cover 3, ensuring a tight seal after the insulation cover 3 and the heating element 9 are fixedly connected, and improving insulation performance.

[0024] The heating assembly 9 includes a first heating element 91, a bottom heating element 92, a second heating element 93, a first fixing hole 94, a second fixing hole 95, and a main body shell 96. The first heating element 91 and the second heating element 93 are respectively fixedly connected to two opposite inner walls of the main body shell 96, and the bottom heating element 92 is fixedly connected to the bottom inner wall of the main body shell 96 to provide a heat source for the oil storage assembly 7. The bottom heating element 92 can preferentially melt the easily solidified oil at the bottom of the oil storage assembly 7, and the heating elements on both sides help to balance the heat, avoid overheating at the bottom and cold oil at the top, improve the uniformity of oil heating, and shorten the low-temperature start-up time.

[0025] The outer walls on both sides of the main body shell 96 are respectively provided with a first fixing hole 94 and a second fixing hole 95, and the positions of the first fixing hole 94 and the second fixing hole 95 are corresponding. The fixing holes provide positioning for the connection between the heat insulation cover 3 and the main body shell 96, ensuring that the heat insulation cover 3 will not shift during installation.

[0026] The oil storage assembly 7 includes a guide channel 71, an oil tank 72, and a level sensor 73. The guide channel 71 is formed on the inner wall of the oil tank 72 in an upward spiral shape to guide the flow of heated oil. An oil tank nozzle 2 is fixedly installed in the central area of ​​the upper end of the oil tank 72, communicating with the interior of the oil tank 72. The outer wall of the oil tank nozzle 2 has external threads for installation with an oil injector. The upward spiral guide channel 71 guides the heated oil to circulate in an orderly manner, avoiding excessive temperature differences caused by turbulent oil flow. To ensure the guide channel 71 achieves optimal effect, the oil level in the cavity of the oil tank 72 should not exceed half the internal depth of the oil tank 72.

[0027] An insulation cover 3 is fixedly installed on the top of the main body shell 96. A first fixing plate 1 and a second fixing plate 4 are fixedly connected to both ends of the insulation cover 3. The first fixing plate 1 has a first threaded hole 11, and the second fixing plate 4 has a second threaded hole 12. The first fixing plate 1 is threadedly connected to the main body shell 96 by a first fixing bolt 5, and the second fixing plate 4 is threadedly connected to the main body shell 96 by a second fixing bolt 6. By providing the fixing plates and the two corresponding fixing holes, the main body shell 96 and the insulation cover 3 can be quickly assembled and disassembled, effectively preventing the insulation cover 3 from falling off.

[0028] The bottom of the insulation cover 3 is fixedly connected to the insulation layer 8, which is used to isolate the heat inside and outside the oil storage tank 72. The insulation layer 8 directly covers the top of the oil storage tank 72, which can effectively prevent the heat of the hot oil in the oil storage tank 72 from being lost upward, reduce the reheating frequency of the heating component 9, reduce energy consumption, and maintain the oil temperature stability.

[0029] A liquid level sensor 73 is fixedly connected through the heat-insulating cover 3, and the lower end of the liquid level sensor 73 penetrates through the upper wall of the oil tank 72 and extends into the cavity to monitor the liquid level inside the tank. The liquid level sensor 73 can effectively monitor the oil level, allowing for timely observation and improving operational safety. Furthermore, the liquid level sensor 73 is a WIKA FLR series float liquid level sensor (explosion-proof type).

[0030] During preparation, first, add oil to the oil tank 72. By observing the level sensor 73, stop adding oil when the oil level reaches a suitable height (not higher than half the depth of the cavity). Then, place the oil tank 72 inside the heat-conducting layer 10, and then place the heat-conducting layer 10 inside the main body shell 96. Finally, cover it with the insulation cover 3. Then, connect the first fixing plate 1 and the main body shell 96 with the first fixing bolt 5, and then connect the first fixing plate 1 and the main body shell 96 with the second fixing bolt 6 to ensure that the insulation cover 3 is firmly connected to the main body shell 96. The preliminary preparation work is then completed.

[0031] During normal operation, the oil injector is first connected via the external thread on the oil tank nozzle 2, and then the heating assembly 9 is activated. At this time, the first heating element 91, the bottom heating element 92, and the second heating element 93 work simultaneously to heat the heat-conducting layer 10. The heat-conducting layer 10 transfers heat to the oil storage assembly 7 while also protecting the oil storage tank 72 from overheating due to direct contact with the heating elements, thus preventing damage. The oil on both sides and at the bottom inside the oil storage tank 72 receives heat first, resulting in higher oil density. At this point, the hot oil exchanges positions with the cold oil above, and then is guided by the guide groove 71. The oil reservoir 72 moves upwards in a spiral motion along its inner wall, exchanging the cold oil that cannot receive heat from the surrounding area with the heated area, thereby improving heating efficiency. At the same time, by guiding the hot oil, it effectively prevents turbulence of the oil, preventing wear on the inner wall of the oil reservoir 72 caused by turbulence. Meanwhile, the insulation layer 8 isolates the heat from the inside and outside, effectively preventing heat loss. During operation, the liquid level in the oil reservoir 72 can be monitored in real time by observing the instrument panel of the liquid level sensor 73. When the liquid level is low, the oil can be added or the heating component 9 can be turned off according to the actual situation, effectively avoiding the problem of dry burning.

[0032] After the work is completed, loosen the first fixing bolt 5 and the second fixing bolt 6, and remove the heat preservation cover 3, the oil storage component 7 and the heating component 9 in sequence. Then remove the oil storage component 7 and perform maintenance or cleaning separately.

[0033] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
