Description

Technical Field

[0001] The utility model belongs to the technical field of lubricating oil production, in particular to a purification device for lubricating oil production. Background Art

[0002] Lubricating oil exists between two objects in relative motion. It plays a vital role and can significantly reduce the friction caused by the contact between the two objects. Specifically, lubricating oil mainly plays a variety of key roles such as lubrication, auxiliary cooling, rust prevention, cleaning, sealing and buffering. Lubricating oil base oil can be mainly divided into three categories: mineral base oil, synthetic base oil and bio-base oil. Among them, mineral base oil is widely used and its usage is also quite large. In order to ensure that the quality and performance of the lubricating oil meet the ideal standards, purification processing through purification equipment is an indispensable step. In the process of this processing and purification, special purification equipment will be used;

[0003] The shortcomings of the existing purification devices for lubricating oil production: the existing purification devices usually first filter the lubricating oil through the filtering structure provided by themselves. However, this filtering structure often presents a relatively complex structure and is difficult to disassemble and maintain. As a result, as time goes by and the number of uses increases, the filtering effect of the filtering structure will inevitably deteriorate, and a certain amount of lubricating oil will remain at the bottom of the filtering structure. Furthermore, in actual applications, it is difficult for the existing evaporation purification devices to achieve uniform heating treatment of the raw materials. Some parts of the raw materials may be overheated, while other parts may be underheated. This will not only affect the efficiency and quality of the entire purification process, but may also result in the final lubricating oil product failing to meet the expected purity requirements. Utility Model Content

[0004] In order to solve the problems raised in the above background technology, the utility model provides a purification device for lubricating oil production, comprising a charging barrel and a filtering structure assembled on the top of the charging barrel, and a uniform stirring structure located below the charging barrel;

[0005] The filtering structure comprises a filtering barrel and a coarse screen, a metal filter and a titanium alloy filter element plugged into the inside of the filtering barrel, the inner wall of the filtering barrel is provided with a plug-in groove adapted to the coarse screen, the metal filter and the titanium alloy filter element, a barrel cover is plugged into the top of the filtering barrel, a stirring sheet is provided below the titanium alloy filter element, and a through hole is provided on the inner bottom wall of the filtering barrel;

[0006] The uniform stirring structure comprises a double-shaft motor and a cross rod fixed at the bottom output end of the double-shaft motor, and a heating component and a rotating component respectively assembled at the bottom center and the four corners of the cross rod.

[0007] Preferably, the heating assembly comprises a support frame and heating rods installed inside the support frame, and the heating rods are arranged in four groups and distributed in a circular array.

[0008] Preferably, the rotating assembly comprises a rotating rod and a rotating sheet rotatably connected to an outer wall of the rotating rod via a bearing, and the rotating sheet is vertically distributed along the rotating rod.

[0009] Preferably, it also includes a support rod located in the middle of the charging barrel and the filter barrel, a discharge pipe assembled on the outer wall of the charging barrel, and an air outlet pipe connected to the charging barrel.

[0010] Preferably, a feed pipe is connected through the inner wall of the through hole, and the bottom end of the feed pipe is connected through the inner top wall of the charging barrel.

[0011] Preferably, the output end at the top of the dual-axis motor is fixedly connected to the bottom end of the stirring blade.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model adopts the design of the filtering structure and the uniform stirring structure, so that the coarse screen, metal filter and aluminum alloy filter element can be easily disassembled from the inside of the filter barrel to achieve the effect of quick cleaning and replacement. In this way, it can be ensured that these filter components always maintain good filtering performance and state, and will not be blocked or fail due to long-term use. When the dual-axis motor is started and the stirring work is carried out, the stirring blade starts to rotate. Under the driving action of the rotation of the stirring blade, the remaining lubricating oil will be gradually pushed until it can pass through the discharge smoothly. The lubricating oil flows into the charging barrel through the tube, and then the lubricating oil flowing into the charging barrel will be stirred by the rotating rod and the rotating plate connected thereto. Since the rotating plate and the rotating rod are rotationally connected, the rotating plate will produce an irregular rotation state when it hits the lubricating oil during stirring, and the heating rod will rotate with the rotation of the rotating plate. In this way, the lubricating oil can be effectively and evenly heated, which not only effectively solves the problems of inconvenient maintenance of the filtering structure and residual lubricating oil, but also can achieve uniform stirring and heating of the lubricating oil, greatly improving the efficiency and quality of the entire purification process.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] like Figures 1 to 5 As shown, the utility model provides a purification device for lubricating oil production, comprising a charging barrel 1 and a filtering structure 2 mounted on the top of the charging barrel 1, and a uniform stirring structure 3 located below the charging barrel 1;

[0022] The filter structure 2 includes a filter barrel 21 and a coarse screen 22, a metal filter 23 and a titanium alloy filter element 24 plugged into the filter barrel 21. The inner wall of the filter barrel 21 is provided with a plug-in groove adapted to the coarse screen 22, the metal filter 23 and the titanium alloy filter element 24. A barrel cover 25 is plugged into the top of the filter barrel 21. A stirring sheet 26 is provided below the titanium alloy filter element 24. A through hole is provided on the inner bottom wall of the filter barrel 21.

[0023] The uniform stirring structure 3 includes a dual-axis motor 31 and a cross rod 32 fixed at the bottom output end of the dual-axis motor 31 , and a heating component 33 and a rotating component 34 respectively assembled at the bottom center and the bottom four corners of the cross rod 32 .

[0024] The above scheme is adopted: through the design of the filtering structure 2 and the uniform stirring structure 3, the coarse screen 22, the metal filter 23 and the aluminum alloy filter element can be easily disassembled from the inside of the filter barrel 21 to achieve the effect of quick cleaning and replacement. In this way, it can be ensured that these filtering components always maintain good filtering performance and state, and will not be blocked or fail due to long-term use. The lubricating oil remaining at the bottom of the filter barrel 21 will drive the stirring blade 26 to start rotating when the dual-axis motor 31 is started and stirring. Under the rotation and driving action of the stirring blade 26, the remaining lubricating oil will be gradually pushed until they can smoothly pass through the discharge pipe 7 and The lubricating oil flows into the loading barrel 1, and then the lubricating oil flowing into the loading barrel will be stirred by the rotating rod 341 and the rotating sheet 342 connected thereto. Since the rotating sheet 342 and the rotating rod 341 are rotationally connected, the rotating sheet 342 will produce an irregular rotation state when it hits the lubricating oil during stirring, and the heating rod 332 will rotate with the rotation of the rotating sheet 342. In this way, the lubricating oil can be effectively and evenly heated, which not only effectively solves the problems of inconvenient maintenance of the filtering structure 2 and residual lubricating oil, but also realizes uniform stirring and heating of the lubricating oil, greatly improving the efficiency and quality of the entire purification process.

[0025] like Figures 1 to 5 As shown, the heating assembly 33 includes a support frame 331 and heating rods 332 installed inside the support frame 331. The heating rods 332 are arranged in four groups and are distributed in a circular array.

[0026] The above solution is adopted: through the design of the heating component 33, the water in the lubricating oil is evaporated by heating, thereby achieving the purification effect.

[0027] like Figures 1 to 5 As shown, the rotating assembly 34 includes a rotating rod 341 and a rotating plate 342 rotatably connected to the outer wall of the rotating rod 341 through a bearing, and the rotating plate 342 is vertically distributed along the rotating rod 341. It also includes a support rod 4 located in the middle of the loading barrel 1 and the filter barrel 21, a discharge pipe 5 assembled on the outer wall of the loading barrel 1, and an air outlet pipe 6 connected through the loading barrel 1.

[0028] The above scheme is adopted: the role of the bearing is to fix the position of the rotating piece 342 and not to prevent the rotating piece 342 from rotating when subjected to force. An electromagnetic valve is provided in the discharge pipe 5, and the lubricating oil after purification can flow out from the discharge pipe 5.

[0029] like Figures 1 to 5 As shown, a feed pipe 7 is connected through the inner wall of the through hole, the bottom end of the feed pipe 7 is connected through the top wall of the charging barrel 1, and the output end of the top of the dual-axis motor 31 is fixedly connected to the bottom end of the stirring blade 26.

[0030] By adopting the above scheme, the lubricating oil remaining on the bottom wall of the charging barrel 1 can be driven by the stirring blade 26 to flow into the discharge pipe 7 through the through hole, and finally flow to the charging barrel 1 through the discharge pipe 7.

[0031] The working principle and use process of this utility model:

[0032] First, open the barrel cover 25, and then pour the lubricating oil into the interior of the filter barrel 21. In this process, when the lubricating oil flows through the coarse screen 22, some relatively large particles and suspended matter will be screened out. Then, the lubricating oil continues to flow, and when passing through the metal filter 23, those smaller impurities can also be successfully filtered out. Then, when passing through the titanium alloy filter element 24, it can adsorb fine impurities. At this point, the lubricating oil smoothly reaches the bottom of the filter barrel 21, and then, start the dual-axis motor 31. When the dual-axis motor 31 starts to rotate, it can drive the stirring blade 26 to rotate, thereby pushing the residual lubricating oil in the filter barrel 21 through the through hole. It flows smoothly into the discharge pipe 7 and then flows to the loading barrel 1. At the same time, the dual-axis motor 31 can also drive the cross rod 32 to rotate. As the cross rod 32 rotates, it will drive the rotating rod 341, the rotating sheet 342, the support frame 331 and the heating rod 332 to rotate together. Since the rotating sheet 342 and the rotating rod 341 are in a rotating connection relationship, when the rotating sheet 342 hits the lubricating oil during the stirring action, an irregular rotation state will be generated, and the heating rod 332 will rotate closely following the rotation of the rotating sheet 342. In this way, the operation of heating and purifying the lubricating oil is realized. During the heating process, the generated gas can be discharged smoothly through the outlet pipe 6, and the lubricating oil after purification can be discharged through the discharge pipe 5.

[0033] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
