Description

Technical Field

[0001] This utility model relates to the field of filtration equipment, and in particular to an ultrafiltration device for low-viscosity industrial oil. Background Technology

[0002] Ultrafiltration is a physical filtration technology based on membrane separation. It uses a membrane with a specific pore size to trap large molecular contaminants in oil while allowing low molecular weight substances to pass through, thereby purifying and regenerating oil. Low-viscosity industrial oils are more likely to pass through ultrafiltration membranes due to their good fluidity and small molecular weight, making them suitable for high-efficiency purification using ultrafiltration technology.

[0003] When treating low-viscosity industrial oils, existing ultrafiltration equipment causes contaminants in the oil to continuously deposit on the surface of the ultrafiltration membrane, forming a dense filter cake layer. This leads to increased transmembrane pressure, a sharp drop in flux, and even complete blockage of the membrane pores. Secondly, ultrafiltration membranes easily adsorb polar substances or colloids in the oil, and unmodified membrane materials are more easily coated with sludge. In addition, improper operating conditions can exacerbate clogging. For example, excessively low oil temperature can cause localized increases in viscosity, or excessive flow can trigger concentration polarization, accelerating the accumulation of contaminants on the membrane surface. Ultimately, all of these factors lead to frequent clogging, requiring downtime to replace the filter screen, resulting in cumbersome, time-consuming, and labor-intensive operations. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a low-viscosity industrial oil ultrafiltration device, which solves the problem that in the existing technology, filter screen clogging requires immediate shutdown and replacement, which is time-consuming, labor-intensive, and affects production.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0006] A low-viscosity industrial oil ultrafiltration device includes an ultrafiltration tank, the inner cavity of which is provided with a filter assembly for filtering the industrial oil, the filter assembly comprising:

[0007] A filter screen is installed inside the ultrafiltration tank. A fixing ring is fixedly connected to the inner cavity of the ultrafiltration tank. The fixing ring is elliptical and inclined and is fixedly connected to the surface of the inner cavity of the ultrafiltration tank. The fixing ring and the filter screen are detachably connected. A cleaning component is provided on the surface of the ultrafiltration tank to clean the surface of the filter screen. An alarm component is provided inside the ultrafiltration tank to remind you of the filtration status of the industrial oil.

[0008] Preferably, an oil pump is fixedly connected to the top of the ultrafiltration tank for conveying raw materials, the outlet of the oil pump is fixedly connected to the inlet of the ultrafiltration tank, and a feeding pipe is fixedly connected to the inlet of the oil pump.

[0009] Preferably, the cleaning assembly includes a cleaning groove formed on the surface of the ultrafiltration tank, the cleaning groove being located above the highest point of the inclined filter screen, and the cleaning groove also having an inclination angle consistent with the inclination angle of the filter screen, and a sealing block being movably connected to the inner cavity of the cleaning groove.

[0010] Preferably, an oil extraction pipe is fixedly connected to the surface of the ultrafiltration tank. One end of the oil extraction pipe penetrates the surface of the ultrafiltration tank and extends into the inner cavity of the ultrafiltration tank. The oil extraction pipe is located above the lowest point of the inclined filter screen, and the extended end of the oil extraction pipe is in contact with the lowest point of the filter screen.

[0011] Preferably, the alarm component includes a light-transmitting block installed inside the ultrafiltration tank, and a slot is formed on the surface of the ultrafiltration tank, with a locking block fixedly connected to the inner cavity of the slot.

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

[0013] 1. The other end of the cleaning tank of this utility model swings in the inner cavity of the ultrafiltration tank, agitating the industrial oil accumulated above the filter screen, thereby causing the industrial oil to flush away the impurities clogging the filter screen pores, thus freeing the pores, increasing the filtration speed, and especially increasing the service life of the filter screen during filtration, preventing production stoppages caused by filter screen clogging. The operation is simple and convenient.

[0014] 2. In this utility model, the filter screen is placed at an angle. After being agitated, the suspended impurities will continuously settle to the lowest point, allowing the upper filter screen to filter normally. The impurities continuously deposited at the lowest point are sucked up by the oil extraction pipe, so that the impurities on the surface of the filter screen can be cleaned in time, which greatly increases the service life of a single use, thereby promoting production increase, reducing the number of replacements, and saving time and effort.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0021] Example 1, please refer to Figures 1-4 This embodiment provides a low-viscosity industrial oil ultrafiltration device, including an ultrafiltration tank 1, a filter screen 2 installed in the inner cavity of the ultrafiltration tank 1, and a fixing ring 3 fixedly connected to the inner cavity of the ultrafiltration tank 1. The fixing ring 3 is elliptical and inclined and fixedly connected to the surface of the inner cavity of the ultrafiltration tank 1. The fixing ring 3 and the filter screen 2 are detachably connected. The connection between the fixing ring 3 and the filter screen 2 is sealed to prevent the industrial oil from contaminating the finished product. The detachable structure of the fixing ring 3 and the filter screen 2 can be used with existing structures.

[0022] An oil pump 4 is fixedly connected to the top of the ultrafiltration tank 1 for conveying raw materials. The outlet of the oil pump 4 is fixedly connected to the inlet of the ultrafiltration tank 1. A feed pipe 5 is fixedly connected to the inlet of the oil pump 4. When the oil pump 4 is connected to a power source and started, it can convey the raw material industrial oil to the inner cavity of the ultrafiltration tank 1 for ultrafiltration.

[0023] A cleaning groove 6 is formed on the surface of the ultrafiltration tank 1. The cleaning groove 6 is located above the highest point of the inclined filter screen 2, and the cleaning groove 6 also has an inclination angle that is consistent with the inclination angle of the filter screen 2. A sealing block 7 is movably connected to the inner cavity of the cleaning groove 6. The sealing block 7 is made of rubber material, so that when the cleaning groove 6 is moved from the outside of the ultrafiltration tank 1, the sealing block 7 deforms but does not leak oil. The other end of the cleaning groove 6 swings in the inner cavity of the ultrafiltration tank 1, agitating the industrial oil accumulated above the filter screen 2. This causes the industrial oil to flush away the impurities clogging the pores of the filter screen 2, thereby freeing the pores, increasing the filtration speed, and especially increasing the service life of the filter screen 2 during filtration. It also prevents production stoppages caused by filter screen clogging during filtration. The operation is simple and convenient.

[0024] Furthermore, since filter screen 2 is placed at an angle, the impurities suspended by the agitation will continuously settle to the lowest point, allowing the upper filter screen 2 to filter normally. The impurities continuously deposited at the lowest point are sucked up by the oil extraction pipe 8, so that the impurities on the surface of filter screen 2 can be cleaned in time, which greatly increases the service life of a single use, thereby promoting production increase, reducing the number of replacements, and saving time and effort.

[0025] Inside the ultrafiltration tank 1, the filtered industrial oil is promptly transported through the outlet at the bottom. However, industrial oil continuously accumulates above the clogged filter screen 2, causing damage to the filter screen and reducing the ultrafiltration quality of the low-viscosity industrial oil. The light-transmitting block 9 at the bottom of the ultrafiltration tank 1 is made of transparent material. External light enters the inner cavity of the ultrafiltration tank 1 through the light-transmitting block 9. There is a difference between the refraction of light through air and through oil. Therefore, when the filter screen 2 becomes clogged, causing the liquid level inside the ultrafiltration tank 1 to rise, different refractions will occur. After being reflected by the card block 11 inside the card slot 10, different colors will appear as feedback, reminding the operator to move the cleaning tank 6 to accelerate filtration. Replace the filter screen after the work is completed to reduce the occurrence of production stoppages due to filter screen clogging.

[0026] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
