Description

Technical Field

[0001] The utility model relates to the technical field of base oil pretreatment, in particular to a 150N base oil pretreatment device. Background Art

[0002] Base oil is the main component of lubricating oil, which is extracted from petroleum or obtained by chemical synthesis. According to its kinematic viscosity, it can be divided into 75N, 150N, 200N and 300N, etc. 150N base oil is mainly used in some lubrication occasions that do not require high viscosity. For example, in some light-loaded industrial gearboxes, 150N base oil can be used as a basic lubricating oil. Dewaxing is a key step in the pretreatment of 150N base oil, because wax will crystallize and precipitate at low temperatures, making the fluidity of the base oil worse. Dewaxing can improve the low-temperature performance of the base oil, so that it can maintain good fluidity at lower temperatures.

[0003] The existing Chinese patent publication number is CN214830139U, which is a lubricating base oil dewaxing equipment. It can be seen from the contents recorded in its specification that the device directly absorbs the treated lubricating base oil when absorbing it, and does not have the step of filtering the discharged lubricating base oil, so that a small amount of wax will remain in the lubricating base oil, affecting the dewaxing effect of the base oil.

[0004] Therefore, it is necessary to provide a new 150N base oil pretreatment device to solve the above technical problems. Utility Model Content

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0028] See also Figures 1 to 5 The embodiment of the utility model provides a 150N base oil pretreatment device, which includes a base frame 1, a treatment barrel 2 is mounted on the base frame 1, and a connected discharge assembly 3 is provided below the treatment barrel 2.

[0029] In the embodiments of the present invention, please refer to Figures 1 to 5 The discharge assembly 3 includes a discharge barrel 31, which is arranged at the bottom of the processing barrel 2. The side wall of the discharge barrel 31 is a hollow structure. A plurality of interconnected transverse connecting pipes 32 and longitudinal connecting pipes 33 are inserted into the interior of the discharge barrel 31. The transverse connecting pipes 32 and the longitudinal connecting pipes 33 are staggered, and a sealing cover 34 is provided at the bottom of the discharge barrel 31.

[0030] It should be noted that: by inserting the interconnected transverse connecting tube 32 and the longitudinal connecting tube 33 inside the discharge barrel 31, a screen structure can be formed inside the discharge barrel 31, and then when the treated base oil is discharged, by injecting coolant into the discharge barrel 31, the coolant flows in the discharge barrel 31, the transverse connecting tube 32 and the longitudinal connecting tube 33, it can be cooled. Then, when the discharged base oil passes through the transverse connecting tube 32 and the longitudinal connecting tube 33 with lower temperature and staggered distribution, the discharged base oil can be filtered and cooled for a second time, thereby reducing the probability of wax residue in the base oil, thereby improving the dewaxing effect of the device on the base oil.

[0031] In the embodiments of the present invention, please refer to Figures 1 to 5 The side wall of the processing cylinder 2 is a hollow structure, and a plurality of interconnected and evenly distributed insert pipes 22 are arranged inside the processing cylinder 2. The insert pipes 22 and the stirring frame 43 are staggered, and a top cover 21 is arranged on the top of the processing cylinder 2. A discharge port 23 is opened in the center of the bottom of the processing cylinder 2. A support cylinder 24 is arranged inside the discharge port 23 at the bottom of the processing cylinder 2. A cylinder 241 is arranged inside the support cylinder 24. A sealing sheet 242 is arranged above the support cylinder 24. The sealing sheet 242 is an umbrella-shaped structure. The inner top of the sealing sheet 242 is against the inner bottom of the processing cylinder 2, and the bottom end of the convex rod in the sealing sheet 242 is slidably inserted into the support cylinder 24 and fixedly connected to the top of the cylinder 241.

[0032] It should be noted that: by providing a connected insert tube 22 inside the treatment barrel 2, during the dewaxing process of the base oil, the insert tube 22 can be cooled by injecting flowing coolant into the insert tube 22 through the staggered distribution between the insert tube 22 and the stirring rack 43. At this time, with the mixing and stirring of the stirring rack 43, the insert tube 22 can be more fully contacted with the base oil, and the wax in the base oil can be condensed on the outer wall of the cooler insert tube 22, thereby achieving the dewaxing process of the base oil.

[0033] By setting the sealing sheet 242, after the base oil is dewaxed, the cylinder 241 can be controlled to extend to push the sealing sheet 242 upward, so that the sealing sheet 242 is separated from the discharge port 23, and the dewaxed base oil can flow to the discharge assembly 3 for discharge.

[0034] In the embodiments of the present invention, please refer to Figures 1 to 5 A stirring assembly 4 for mixing the base oil is provided inside the treatment cylinder 2, the stirring assembly 4 includes a stirring frame 43, the stirring frame 43 is rotatably arranged in the treatment cylinder 2, and the stirring frame 43 is a hollow tube structure, the stirring assembly 4 also includes a top frame 41, the top frame 41 is fixedly arranged on the top cover 21, a driving motor 411 is provided at the inner top of the top frame 41, and a fixedly connected adapter cylinder 42 is provided at the output end of the driving motor 411, the outer wall of the adapter cylinder 42 is rotatably connected to the inside of the top cover 21, a partition 421 is provided inside the adapter cylinder 42, and both sides of the bottom partition 421 of the adapter cylinder 42 are connected to the top of the stirring frame 43, and both sides of the side wall partition 421 of the adapter cylinder 42 are provided with connecting holes 422, and a connecting cover 44 that is rotatably connected is sleeved on the outside of the adapter cylinder 42 and the corresponding connecting hole 422. The bottom of the connecting cover 44 is fixedly connected to the top cover 21, and the inside of the connecting cover 44 is connected to the corresponding liquid inlet tee pipe 531 and liquid return tee pipe 541.

[0035] It should be noted that: through the rotational connection between the adapter cylinder 42 and the connecting cover 44, and the partition 421 is set up inside the adapter cylinder 42, when the driving motor 411 drives the adapter cylinder 42 to rotate, the adapter cylinder 42 drives the stirring frame 43 located inside the processing cylinder 2 to rotate stably inside the top cover 21, and at this time, the connecting cover 44 can be stably located outside the connecting hole 422 on the side wall of the adapter cylinder 42, so that when the coolant flows into the connecting cover 44 through the liquid inlet three-way pipe 531, it can smoothly flow into the adapter cylinder 42 and the stirring frame 43 connected thereto through the connecting hole 422 inside the connecting cover 44, thereby realizing the cooling of the stirring frame 43, and then during use, the cooling area and cooling uniformity of the base oil can be increased, so that the wax in the base oil can be more completely condensed and separated from the base oil.

[0036] In the embodiments of the present invention, please refer to Figures 1 to 5A temperature control component 5 for controlling the temperature of the processing cylinder 2 is provided on one side of the top of the base frame 1. The temperature control component 5 includes a heating box 51 and a refrigeration box 52. The heating box 51 and the refrigeration box 52 are both arranged on the base frame 1. The tops of the heating box 51 and the refrigeration box 52 are both provided with a connected liquid inlet column 53 and a liquid return column 54. A plurality of connected liquid inlet tees 531 are arranged between the two liquid inlet columns 53, and a plurality of connected liquid return tees 541 are arranged between the two liquid return columns 54. The liquid inlet tee 531 and the liquid return tee 541 are both connected to the processing cylinder 2 and the discharge cylinder 31.

[0037] It should be noted that: through the setting of the temperature control component 5, when using the present device, the staff can flexibly control the temperature inside the treatment cylinder 2 as needed, so that the wax in the base oil can be condensed and separated when the base oil is dewaxed and discharged. When the base oil is discharged, the condensed wax can be melted, thereby facilitating the discharge of the separated wax.

[0038] The working principle of the 150N base oil pretreatment device provided by the utility model is as follows;

[0039] When using the device, the top cover 21 can be opened first, and 150N base oil can be added into the treatment barrel 2, and then the top cover 21 and the treatment barrel 2 can be connected and sealed, and then the liquid inlet tee pipe 531 and the liquid return tee pipe 541 connected to the connecting cover 44 can be connected to the liquid inlet pipe column 53 and the liquid return pipe column 54. After the pipelines are connected, the drive motor 411 can be controlled to drive the adapter barrel 42 to rotate;

[0040] The rotating adapter cylinder 42 can drive the stirring frame 43 connected thereto to rotate simultaneously inside the top cover 21. In this process, the refrigerator outside the refrigeration box 52 can be used to refrigerate the coolant in the refrigeration box 52. At this time, under the operation of the pump body, the refrigerated coolant can flow into the corresponding processing cylinder 2 and the connecting cover 44 through the liquid inlet column 53 and the liquid inlet tee pipe 531.

[0041] At this time, the cooling liquid entering the side wall of the treatment cylinder 2 from the bottom can flow into the internally connected insert tube 22. When the cooling liquid fills the space on the side wall of the treatment cylinder 2, it can flow back to the refrigeration box 52 through the liquid return tee 541 and the liquid return pipe column 54. Since the connecting cover 44 and the adapter cylinder 42 are rotatably connected, the cooling liquid entering the connecting cover 44 will flow into the adapter cylinder 42 and the stirring rack 43 connected thereto through the corresponding connecting holes 422. When the stirring rack 43 is filled with the cooling liquid, it can flow back to the other side of the partition 421 inside the adapter cylinder 42, and flow back to the liquid return tee 541 through the connecting hole 422 opposite thereto, so as to flow back to the refrigeration box 52 through the liquid return pipe column 54 connected to the liquid return tee 541.

[0042] At this time, during the rotation of the stirring rack 43, the stirring rack 43 can be more fully in contact with the internal 150N base oil through the staggered distribution with the insert tube 22, thereby improving the cooling uniformity of the 150N base oil, so that the wax in the 150N base oil can be condensed on the outer wall of the insert tube 22 and the stirring rack 43;

[0043] After the dewaxing treatment of the 150N base oil is completed, the sealing cover 34 at the bottom of the discharge barrel 31 can be unscrewed first, and the collection barrel used for collection can be moved to the bottom of the discharge barrel 31, and then the cylinder 241 can be controlled to extend to drive the sealing sheet 242 to move upward, so that it can release the seal of the discharge port 23. At this time, the 150N base oil in the treatment barrel 2 can flow downward through the discharge port 23 to the discharge assembly 3;

[0044] Since a plurality of interconnected and staggered transverse connecting tubes 32 and longitudinal connecting tubes 33 are provided inside the discharge barrel 31 in the discharge assembly 3, a multi-layer staggered filter structure can be formed inside the discharge barrel 31, and when the flowing coolant flows inside the discharge barrel 31, the transverse connecting tubes 32 and the longitudinal connecting tubes 33, the coolant can be cooled. Therefore, when the base oil flows downward from the staggered transverse connecting tubes 32 and the longitudinal connecting tubes 33, the multi-layer staggered cooling filter structure formed by the transverse connecting tubes 32 and the longitudinal connecting tubes 33 can perform more precise secondary cooling on the flowing base oil, thereby reducing the probability of wax residue in the base oil, thereby improving the dewaxing effect of the device on the base oil, and completing the dewaxing pretreatment of the base oil.

[0045] After the base oil is discharged, the valves on the side of the liquid inlet tee 531 and the liquid return tee 541 connected to the refrigeration box 52 can be closed first, and the valve on the side of the heating box 51 can be opened, and the heating rod in the heating box 51 can be controlled to work, so that when the pump body in the heating box 51 is working, the heated coolant in the heating box 51 can be input into the side wall of the processing cylinder 2, the stirring frame 43 and the discharge cylinder 31. Through the flow of the coolant with relatively high temperature, the condensed wax on the processing cylinder 2, the insert tube 22, the stirring frame 43 and the discharge cylinder 31 can be melted, so that the separated wax can be discharged to the outside, so as to facilitate the subsequent dewaxing treatment of the base oil.

[0046] The circuits and controls involved in the present invention are all prior art and will not be described in detail here.

[0047] The above are only embodiments of the present invention, and are not intended to limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made using the contents of the specification and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
