Abstract
Description
Technical Field
[0001] This utility model relates to the field of lubricating oil regeneration technology, specifically a constant temperature heating device for lubricating oil regeneration. Background Technology
[0002] Traditional devices for heating and removing water from waste lubricating oil are generally oil refining pots. However, these devices have several drawbacks. For example, during the heating process, water in the waste lubricating oil evaporates and is released into the atmosphere. Some impurities with pungent odors in the waste lubricating oil are also released into the atmosphere along with the water vapor. In the process of heating waste lubricating oil in the oil refining pot, the waste lubricating oil closer to the pot wall heats up faster, while the waste lubricating oil in the center is colder than that near the pot wall. The temperature needs to be transferred slowly to the waste lubricating oil in the center, which leads to uneven heating and a situation where some lubricating oil is heated to a higher temperature than others. Utility Model Content

[0024] Figures 1-3 This is one embodiment of the present invention, and the specific problem addressed by this embodiment is as follows: Traditional devices for heating and removing water from waste lubricating oil are generally oil refining pots, which have many drawbacks in use. For example, during the heating process of waste lubricating oil, water in the waste lubricating oil evaporates and is discharged into the outside atmosphere. Some impurities with irritating odors in the waste lubricating oil are also discharged into the outside atmosphere along with the evaporating water vapor. During the heating process of the oil refining pot, the waste lubricating oil closer to the pot wall heats up faster, while the temperature of the waste lubricating oil in the center is lower than that near the pot wall. The temperature needs to be slowly transferred to the waste lubricating oil in the center, which leads to uneven heating and a situation where some lubricating oil is heated to a higher temperature than others. The problems of the prior art can be summarized as poor exhaust gas treatment during lubricating oil regeneration and inconsistent oil temperature during the heating process. Based on this, this solution describes a constant temperature heating device for lubricating oil regeneration. It utilizes a tail gas treatment component 2 installed between two heating reaction vessels 1 to remove water vapor and adsorb tail gas overflowing from the vessel body 11. Meanwhile, a stirring component 12 installed inside the vessel body 11 generates centripetal agitation of the lubricating oil through vertical action. This generates movement of the lubricating oil inside the vessel body 11, thereby increasing the effect of uniform lubricating oil temperature.
[0025] It is based on the existing heating reactor 1 and is set up symmetrically on both sides. The two heating reactors 1 are connected by a tail gas treatment component 2. The tail gas treatment component 2 includes a treatment chamber 21 and a treatment cavity 22 inside the treatment chamber 21. A support column 4 is installed on the bottom surface of the treatment chamber 21 to maintain its height on the two heating reactors 1. The treatment cavity 22 forms a condensation cavity 221 and an adsorption cavity 222 through a partition 23 installed at the center. Several pores are installed on the partition 23 to establish a flow path for the tail gas after it is separated from the water vapor into the adsorption cavity 222. Several condensation water pipes 25 connected to a water source are installed on the bottom surface of the treatment chamber 21. A water outlet is opened on one side wall of the condensation cavity 221. A gas supply pipe 24 for overflowing tail gas is installed on the top surface of the treatment chamber 21. The gas supply pipe 24 is connected to the adsorption cavity 222 and the adsorption cavity 222 is filled with activated carbon. Water flows through the condenser pipe 25, which lowers the temperature of the bottom plate of the treatment chamber 21. This causes all the water vapor entering the condenser cavity 221 to condense on the bottom plate of the treatment chamber 21, preventing it from moving upwards and entering the adsorption cavity 222, thus causing the activated carbon to become damp.
[0026] A condensing device 3 extending into the adsorption cavity 222 is installed on the heating reactor 1. In this embodiment, the condensing device 3 is specifically a U-shaped conveying pipe. The heating reactor 1 includes a reactor body 11. The condensing device 3 extends into the interior of the heating reactor 1 to establish a channel for conveying water vapor into the adsorption cavity 222. An agitator 12 is installed inside the reactor body 11. The agitator 12 acts vertically in the inner cavity of the reactor body 11.
[0027] The stirring component 12 includes a driving component 121 mounted on the outer wall of the vessel body 11. In this embodiment, the driving component 121 is specifically a drive motor. The driving component 121 extends into the inner cavity of the vessel body 11 via a shaft and is connected to a cylinder mounting sleeve 122. An extension rod 123 is connected to the lower end of the cylinder mounting sleeve 122. The cylinder is located inside the cylinder mounting sleeve 122 and its free end extends into the cylinder mounting sleeve 122 and is connected to the extension rod. Several stirring rods 124 are circumferentially and equidistantly mounted on the extension rod 123. Under the action of the driving component 121, the extension rod 123 rotates and drives the stirring rods 124 to rotate, causing the oil to rotate within the vessel body 11 and increasing the aggregation of floating objects towards the center. A filter sleeve 125 is mounted on the rod body of the extension rod 123 at the lower end of the stirring component, which can filter the floating objects on the upper part of the lubricating oil after the lubricating oil is heated. The system retrieves floating debris and cleans impurities mixed with waste lubricating oil, further improving the quality of lubricating oil regeneration. The filter sleeve 125 includes a cylinder 1251, with inlets 1252 on the top and side walls of the cylinder 1251. Several overflow holes 1253 for fluid overflow are provided at the lower end of the inlets 1252 on the side walls. The overflow hole 1253 at the bottom is spaced apart from the bottom of the cylinder 1251. Floating debris enters through the inlet 1252 and is lifted off the oil surface by the extension rod 123 by the cylinder. The oil overflows from the overflow, while the floating debris remains inside the cylinder 1251. Since the overflow hole 1253 at the bottom is spaced apart from the bottom of the cylinder 1251, it will not become clogged after one retrieval, increasing the continuous usability of the equipment.
[0028] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.
