Description

Technical Field

[0001] The utility model relates to the technical field of petrochemical equipment, in particular to a stirring device for lubricating oil production. Background Art

[0002] Lubricating oil generally consists of two parts: base oil and additives. Base oil is the main component of lubricating oil and determines the basic properties of lubricating oil. Additives can make up for and improve the deficiencies in the performance of base oil and impart certain new properties. In the process of lubricating oil processing and production, a stirring device is required to ensure that the lubricating oil and additives are fully mixed.

[0003] The Chinese patent with announcement number CN220715549U proposes a stirring device for lubricating oil production, including: a barrel body, a stirring rod is arranged inside the barrel body; a feeding pipe is arranged at the top of the barrel body; a disassembly component is symmetrically arranged on the top of the barrel body, and the disassembly component includes: a mounting groove, opened at the top of the barrel body; a clamping groove, symmetrically opened on the inner side wall of the mounting groove; a mounting block, arranged inside the mounting groove; a heating tube, arranged at the bottom of the mounting block; a rotating rod, rotatably arranged inside the mounting block, and the top protrudes from the inner side wall of the mounting block; an elliptical plate, arranged on the outer side wall of the rotating rod; an insertion rod, one end of which is symmetrically arranged inside the mounting block and one end passes through the inner side wall of the mounting block; a stopper, arranged at one end of each of the insertion rods; a spring, arranged on the outer side wall of each of the insertion rods.

[0004] Although the above device can complete the stirring of the lubricating oil, there are the following two problems:

[0005] First, the electric heating tube is in direct contact with the lubricating oil. Since the electric heating rod is directly exposed to the lubricating oil, some chemical components in the lubricating oil and its additives may corrode the material of the electric heating rod, accelerate the wear of the electric heating rod, and thus shorten its service life. In addition, when the electric heating rod is in direct contact with the lubricating oil, a high-temperature area may be formed around the rod body, which causes local overheating of the lubricating oil. The local high temperature will not only destroy the chemical stability of the lubricating oil, but also may cause thermal decomposition or thermal oxidation of some components in the lubricating oil, thereby affecting the overall quality of the lubricating oil.

[0006] Second, there is a lack of air pressure regulating device. During the process of the electric heating tube heating the lubricating oil, if the upper port of the feeding tube is in an open state, light hydrocarbons, sulfur-containing and oxygen-containing organic compounds in the lubricating oil and volatile components in the additives will escape, which not only pollutes the environment but also causes a waste of resources; if the upper port of the feeding tube is in a closed state, then as the electric heating tube heats the lubricating oil, the air pressure in the barrel will increase, which may cause damage to the barrel.

[0007] Therefore, we propose a stirring device for lubricating oil production to solve the above problems. Summary of the invention

DETAILED DESCRIPTION

[0031] In order to make the purpose, technical solution and advantages of the embodiments of the present utility model clearer, the technical solution in the embodiments of the present utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the present utility model.

[0032] The present application provides a stirring device for lubricating oil production, which is mainly used to solve the problem that the electric heating tube is directly in contact with the lubricating oil in the prior art. Since the electric heating rod is directly exposed to the lubricating oil, certain chemical components in the lubricating oil and its additives may corrode the material of the electric heating rod, accelerate the wear of the electric heating rod, and thus shorten its service life. In addition, when the electric heating rod is in direct contact with the lubricating oil, a high-temperature area may be formed around the rod body, which causes local overheating of the lubricating oil. The local high temperature will not only destroy the chemical stability of the lubricating oil, but may also cause thermal decomposition or thermal oxidation of some components in the lubricating oil, thereby affecting the overall quality of the lubricating oil. The following technical solutions are provided, which will be combined with Figure 1-Figure 4 Make a detailed description:

[0033] A stirring device for lubricating oil production, comprising:

[0034] A mixing drum 1, the bottom end of which is conical and connected to a discharge pipe 101, a discharge valve being installed at the mouth of the discharge pipe 101;

[0035] A feed pipe 2 is connected to the top of the mixing drum 1;

[0036] The heating element 3 is used to heat the lubricating oil. The heating element 3 includes a heat pipe 301 in an annular array embedded in the mixing drum 1. Electric heating rods 302 are installed at equal intervals on the top of the mixing drum 1. The heating ends of the electric heating rods 302 extend into the interior of the heat pipe 301.

[0037] The stirring mechanism 4 is arranged in the middle of the mixing drum 1 and is used to stir the lubricating oil in the mixing drum 1;

[0038] The air pressure regulating member 5 is symmetrically arranged above both sides of the mixing drum 1. The air pressure regulating member 5 is used to stabilize the air pressure inside the mixing drum 1. The air pressure regulating member 5 includes a fixed drum 501 connected to the upper side of the mixing drum 1. A sliding rod 502 is slidably inserted in the middle of one end of the fixed drum 501 away from the mixing drum 1. A sliding plug 503 is fixedly arranged at one end of the sliding rod 502 located inside the fixed drum 501. The sliding plug 503 is slidably connected to the wall of the fixed drum 501. A limiting disk 504 is fixedly arranged at one end of the sliding rod 502 located outside the fixed drum 501.

[0039] The base 6 is arranged directly below the mixing drum 1 , and is used for movably supporting the mixing drum 1 .

[0040] Workflow Description:

[0041] The first step is to prepare the lubricating oil and additives, ensure that the mixing drum 1 is clean, and first add all the lubricating oil into the mixing drum 1 through the feed pipe 2;

[0042] The second step is to start the heating element 3, the electric heating rod 302 works, and the heat is transferred to the heat pipe 301, so that the lubricating oil reaches a suitable stirring temperature;

[0043] The third step is to start the stirring mechanism 4 and add additives in batches through the feed pipe 2 to achieve sufficient mixing of the lubricating oil and the additives. During the stirring process, the air pressure regulating member 5 can automatically adjust the air pressure to keep the air pressure in the barrel stable. The specific working principle is that when the electric heating rod 302 heats the lubricating oil, the light hydrocarbons, sulfur-containing and oxygen-containing organic compounds in the lubricating oil and the volatile components in the additives are converted into gas, and the air pressure in the mixing barrel 1 increases, which will push the sliding plug 503 to move toward the end of the fixed barrel 501, thereby keeping the air pressure in the mixing barrel 1 stable.

[0044] The stirring device for lubricating oil production is provided with a heating element 3, and the electric heating rod 302 is embedded in the interior of the heat conducting tube 301, and an indirect heating method is adopted to reduce the direct contact between the electric heating rod 302 and the lubricating oil, reduce chemical corrosion, and extend the service life of the equipment. At the same time, local overheating is avoided, the chemical stability of the lubricating oil is maintained, and thermal decomposition or thermal oxidation is prevented. In addition, an air pressure regulating element 5 is provided, which has an automatic air pressure regulating function, avoids damage to the stirring drum 1 due to excessive air pressure, improves the safety of the production process, and reduces the escape of volatile components, thereby reducing environmental pollution and waste of resources.

[0045] like Figure 3 As shown, in some embodiments, the fixed barrel 501 is arranged to be inclined upward. More specifically, the fixed barrel 501 is arranged to be inclined upward. This arrangement has two major advantages. First, when the electric heating rod 302 stops heating the lubricating oil, the light hydrocarbons, sulfur-containing and oxygen-containing organic compounds and volatile components in the additives in the lubricating oil begin to condense, and the condensate can quickly flow back into the mixing barrel 1 under the action of its gravity. Second, as the light hydrocarbons, sulfur-containing and oxygen-containing organic compounds and volatile components in the additives in the lubricating oil begin to condense, the air pressure in the mixing barrel 1 decreases, and the sliding plug 503 will slide down to the initial position under the action of its gravity without the need for manual operation, which is more convenient.

[0046] like Figure 4 As shown, in some embodiments, the upper port of the feed pipe 2 is internally threadedly connected to a plunger 7, and a handle is fixedly provided on the side wall of the plunger 7. More specifically, the feed pipe 2 can be sealed by setting the plunger 7 to prevent the light hydrocarbons, sulfur-containing and oxygen-containing organic compounds, and volatility in the additives from escaping to the outside during the process of heating the lubricating oil by the electric heating rod 302.

[0047] like Figure 4 As shown, in some embodiments, a feed groove 701 is constructed on the top of the plunger 7, and a leakage hole 702 is constructed on the bottom of the plunger 7. The leakage hole 702 is conical and communicated with the bottom of the feed groove 701. A cross plate 8 is fixedly provided in the middle of the feed pipe 2, and a conical protrusion 9 is fixedly provided on the top of the cross plate 8. The conical protrusion 9 is slidably connected with the leakage hole 702. More specifically, when adding lubricating oil, the plunger 7 can be completely taken out by rotation, so that a large amount of lubricating oil can quickly enter the mixing drum 1. When adding additives, the plunger 7 can be rotated upward so that the conical protrusion 9 is separated from the leakage hole 702 by a suitable distance, so that the additive can slowly fall into the mixing drum 1 and fully contact with the lubricating oil. When the heating rod is heating the lubricating oil, the plunger 7 can be rotated downward so that the conical protrusion 9 is completely embedded in the leakage hole 702, so that light hydrocarbons, sulfur-containing and oxygen-containing organic compounds and volatility in the additive cannot escape to the outside.

[0048] like Figure 3 As shown, in some embodiments, the stirring mechanism 4 includes a motor 401 installed in the middle of the top of the mixing drum 1, the output shaft of the motor 401 penetrates the top wall of the mixing drum 1 and is connected to a mounting rod 402, first stirring rods 403 are fixedly provided at equal intervals on both sides of the surface of the mounting rod 402, and second stirring rods 404 are fixedly provided at equal intervals on the bottom side of the first stirring rod 403, and the second stirring rod 404 is tapered. More specifically, when the motor 401 is working, its output shaft drives the mounting rod 402 to rotate. The first stirring rod 403 and the second stirring rod 404 rotate with the mounting rod 402 to stir the lubricating oil, and the tapered design of the second stirring rod 404 can avoid the adhesion of the lubricating oil and facilitate daily maintenance and cleaning.

[0049] like Figure 1 As shown, in some embodiments, the base 6 includes a support rod 601 fixedly arranged in a circular array on the bottom side of the mixing drum 1, a carrying plate 602 is fixedly arranged at the bottom of the support rod 601, a self-locking universal wheel 603 is installed at the bottom of the carrying plate 602, and a positioning groove 6021 is opened in the middle of the top of the carrying plate 602. More specifically, the support rod 601 is fixedly arranged in the form of a circular array on the bottom side of the mixing drum 1, and its main function is to support the weight of the mixing drum 1 and the material inside it. The use of the carrying plate 602 increases the stability of the mixing device and effectively prevents shaking caused by uneven ground. The design of the positioning groove 6021 enables the collection bucket to be accurately placed under the mixing drum 1, and the design of the self-locking universal wheel 603 enables the mixing device to be easily moved to different positions according to work requirements, and locked when in use, thereby ensuring the safety and stability of the mixing process.

[0050] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
