Description

Technical Field

[0001] This utility model belongs to the field of lubricating oil purification technology, and more specifically, it relates to a centralized oil purification system for purifying the lubricating oil of the sealing ring of an internal mixer. Background Technology

[0002] In recent years, the purification, filtration, and recycling of industrial lubricating oils have been rapidly promoted in enterprises that use a large amount of lubricating oil. However, the use of general oil filtration equipment such as vacuum oil filters and oil filtration carts has significant limitations, especially for the purification and filtration of lubricating oil for sealing rings in internal mixers in the tire industry. Due to the structure of the internal mixer, a large amount of carbon black, small materials, and rubber leak from the rotor mechanical seal ring during normal production, contaminating the sealing ring lubricating oil. This results in a serious excess of impurities in the sealing ring lubricating oil, which cannot meet the requirements for recycling and can only be disposed of as hazardous waste (HW-08) with a fee. This increases the environmental pressure on enterprises and also increases production costs. Traditional filter elements are easily clogged, resulting in high costs and low efficiency. Moreover, the rubber mixed in has a certain compatibility with the lubricating oil, making it difficult to remove through filtration. The residual rubber impurities can easily clog oil pipelines, plunger pumps, distributors, and other equipment, affecting the normal operation of the equipment. Therefore, rubber and tire enterprises urgently need a lubricating oil purification and filtration equipment that can effectively remove rubber impurities and operate at low cost. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a centralized oil purification system for purifying lubricating oil in the sealing rings of internal mixers. This system solves the problems of traditional filter elements being prone to clogging, high cost, low efficiency, and the fact that the mixed rubber has a certain compatibility with the lubricating oil, making it difficult to remove through filtration. The residual rubber impurities easily clog oil pipelines, plunger pumps, distributors, and other equipment, affecting the normal operation of the equipment.

[0004] This utility model discloses a centralized oil purification system for purifying lubricating oil in the sealing rings of an internal mixer, achieved through the following specific technical means:

[0005] A centralized oil purification system for purifying lubricating oil in the sealing rings of an internal mixer includes a feeding tank; the bottom outlet of the feeding tank is connected to the inlet of a feeding pump via a pipe; the outlet of the feeding pump is connected to the inlet of an oil storage tank via a pipe; the outlet of the oil storage tank is connected to a heater; the heater is connected to a vacuum purifier via valve A; a packing bed is provided inside the vacuum purifier; the outlet of the vacuum purifier is connected to a dehydration discharge gear pump via a pipe; the dehydration discharge gear pump is connected to the oil storage tank via an electric three-way ball valve; the electric three-way ball valve is connected to a mesoporous adsorption filter; the bottom of the mesoporous adsorption filter is connected to a supplementary filter; the supplementary filter is connected to the oil storage tank; the oil storage tank is connected to a degumming machine via a degumming feed pump; the degumming machine is connected to a degumming transfer box; the degumming transfer box is connected to the oil storage tank via a degumming circulation gear pump.

[0006] Furthermore, the inside of the feeding box is equipped with a metal wire mesh; the metal wire mesh is configured with a mesh size of 50-120; and a liquid level display is installed on the feeding box.

[0007] Furthermore, the oil storage tank is equipped with a liquid level display; an agitator roller is installed inside the oil storage tank via a motor; and an electric heating wire is installed inside the heater.

[0008] Furthermore, the vacuum gasification tank is equipped with a liquid level display; the vacuum gasification tank is connected to a forced-air condenser; the forced-air condenser is connected to a water collection tank; and the water collection tank is connected to a vacuum pump via valve B.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. In this device, waste lubricating oil undergoes degumming pre-separation, vacuum dehydration, mesoporous adsorption filtration, and supplementary precision filtration. This process removes over 90% of particulate matter and colloidal impurities, significantly reducing the amount of subsequent filter cartridges required. A high-efficiency vacuum aerator with a packing design greatly increases the evaporation area of ​​the material, effectively improving dehydration efficiency and rapidly removing contaminated water from the lubricating oil, ensuring the water content meets new oil standards. A mesoporous adsorption filter utilizes the selective adsorption mechanism of mesoporous adsorption fibers to selectively adsorb and filter polar organic impurities such as sludge oxides and gum asphalt in the lubricating oil. This effectively extends the lubricating oil film formation cycle, reduces wear on equipment friction pairs, and the mesoporous adsorption filter has a large dirt-holding capacity—10 times that of ordinary filter cartridges. The viscosity, moisture, and mechanical impurity indicators of the lubricating oil fully meet the equipment's operating requirements. Furthermore, it reduces lubricating oil procurement costs, achieving energy conservation and consumption reduction goals. This device is suitable for the purification of highly contaminated lubricating oils such as those used in internal mixer sealing rings. Attached Figure Description

Oil storage tank 3 is equipped with a stirring roller 301. During the feeding process, the stirring roller 301 is activated to stir the oil, preventing impurities from settling at the bottom of the tank and affecting the discharge; after the oil in oil storage tank 3 reaches the set liquid level, vacuum pump 17 automatically starts. Under negative pressure, the oil in oil storage tank 3 enters vacuum evaporator 5 via heater 4. Vacuum evaporator 5 adopts a packing design, with Raschig rings, Pall rings, and other packing beds inside to increase the material evaporation area. The vacuum degree inside vacuum evaporator 5 is controlled between -0.09 MPa and -0.0.07MPa, heating temperature set to 60℃-75℃, the oil in vacuum gasification tank 5 is returned to oil storage tank 3 via dehydration discharge gear pump 7, realizing a circulating heating and dehydration process. The circulating dehydration time can be set by the user. The dehydration discharge gear pump 7 achieves stable transportation of high solids content media by strengthening gear rigidity, optimizing sealing structure and intelligent pulsation suppression. When the gears disengage, the volume increases, and waste oil is drawn into the gear groove. When the gears re-engage, the volume is compressed, and the waste oil is forcibly squeezed out.

The oil after two-stage filtration is filled into standard oil drums for recycling in the internal mixer. The degumming feed pump 11 achieves the degumming process by generating centrifugal separation through rotation.
