Description

Technical Field

[0001] This utility model relates to the field of rolling oil filtration technology, and in particular to a rolling oil filtration device. Background Technology

[0002] Rolling oil is a liquid medium applied to the surface of rolls and workpieces during the metal rolling process. It serves to lubricate, cool, clean, and prevent rust, thereby improving the rolling process, enhancing the quality of rolled products, and increasing production efficiency.

[0003] Moreover, most rolling oil can be reused through recycling, which can reduce environmental pollution and costs. With the development of oil processing technology, the filtration effect of oil is also getting better and better. Existing finished oil, whether it is produced or recycled, will inevitably contain some impurities, such as oil residue and debris. The current technology of filtering rolling oil only uses devices such as filter screens or filter plates for natural filtration, which takes a long time and cannot fully filter the rolling oil. In addition, cleaning the filter plates is troublesome, which reduces the work efficiency of workers and the filtration quality is not good. Utility Model Content

[0004] To address the problem of incomplete filtration in existing technologies, this invention provides a rolling oil filtration device.

[0005] The technical solution of this utility model is achieved through the following scheme: a rolling oil filtration device, including a filter cylinder, an oil inlet pipe, a first filtration system and a second filtration system. A through-hole shaft is rotatably mounted on the filter cylinder. The oil inlet pipe is connected to one end of the through-hole shaft through a rotary joint. The through-hole shaft is connected to a first motor through a bevel gear transmission component. The other end of the through-hole shaft is connected to the first filtration system. The first filtration system and the second filtration system are installed sequentially from top to bottom in the inner cavity of the filter cylinder. The filter cylinder is provided with a return oil pipe. The oil inlet end of the return oil pipe is connected to the filter cylinder, and the oil outlet end of the return oil pipe is located between the first filtration system and the second filtration system.

[0006] The above technical solution involves a first filtration system to initially filter and intercept larger particles, reducing the burden on subsequent filtration systems. The oil then enters a second filtration system for deep purification, further removing finer impurities and ensuring higher purity of the filtered rolling oil. The oil is then circulated through a return pipeline, increasing the number of filtration cycles and allowing the oil to participate in the filtration process again, improving filtration adequacy and further guaranteeing filtration quality. A bevel gear drive rotates the through-hole shaft, causing the first filtration system to rotate within the filter cylinder. This rotation increases the contact area and frequency with the rolling oil, promoting its flow and accelerating its passage through the first filtration system, thus shortening the filtration time.

[0007] Preferably, the first filtration system includes a filter drum and a first filter screen, wherein the filter drum is flange-connected to a through-hole shaft, and the first filter screen is detachably mounted on a filter drum below the filter drum.

[0008] Preferably, a liquid-limiting outer cylinder is installed inside the filter cylinder, and the liquid-limiting outer cylinder is sleeved on the filter rotating cylinder.

[0009] Through the above technical solutions, the flange connection can ensure the stability of the filter drum during operation, reduce equipment failures or leaks caused by loose connections, and allow the filter drum to be easily installed and removed from the through-hole shaft. The liquid-limiting outer cylinder restricts the flow range of liquid in the filter drum, allowing the liquid to pass through the filter drum and the first filter screen more concentratedly for filtration, avoiding disorderly flow of liquid in the filter drum, reducing the residence time of liquid in non-filtration areas, thereby improving filtration efficiency. The liquid-limiting outer cylinder can also play a certain protective role for the filter drum, reducing the direct impact of liquid on the filter drum.

[0010] Preferably, the second filtration system includes a second filter screen and an agitator fan, wherein the top surface of the agitator fan is connected to the second filter screen via a rotating shaft, and the bottom surface of the agitator fan is connected to a second motor.

[0011] Through the above technical solution, the agitator fan rotates synchronously with the second filter screen. The agitation of the agitator fan not only prevents oil sedimentation, but also provides a certain auxiliary filtration effect on the oil on the second filter screen, promoting faster oil passage through the second filter screen. It also prevents the oil returning from the return oil pipeline from impacting a single position for a long time, extending the service life of the second filter screen and ensuring that the returned oil can be evenly distributed and participate in the filtration process again, thus improving the sufficiency and thoroughness of filtration.

[0012] Preferably, the oil inlet of the return oil pipeline is located on one side of the agitator fan, and the oil inlet of the return oil pipeline is fixedly installed on the inner wall of the filter cylinder by a snap fastener.

[0013] Preferably, the filter cartridge has a sealing door on its side, and the sealing door has an observation window.

[0014] Preferably, the oil inlet end of the return oil pipeline is toothed.

[0015] Through the above technical solutions, the agitator fan will agitate the oil during rotation, making the oil flow in the area more active. The return oil pipeline can more effectively draw in the oil after preliminary filtration and agitation, improving the return oil efficiency. The toothed oil inlet can effectively avoid air stagnation, ensuring that the returned oil can participate in the subsequent filtration cycle in a timely manner. The clip can withstand a certain amount of vibration and impact, ensuring the stability of the position of the oil inlet of the return oil pipeline and avoiding the impact of loosening or displacement on the return oil function, thus improving the operational reliability of the equipment.

[0016] In summary, this utility model has the following beneficial effects:

[0017] 1. This utility model uses a first filtration system for preliminary filtration, intercepting larger-diameter impurities and reducing the burden on subsequent filtration systems. The oil then enters a second filtration system for deep purification, further removing finer impurities and ensuring higher purity of the filtered rolling oil. The oil is circulated through a return pipeline, increasing the number of filtration cycles and allowing the oil to participate in the filtration process again, improving filtration adequacy and further guaranteeing filtration quality. A bevel gear transmission component drives the through-hole shaft to rotate, causing the first filtration system to rotate within the filter cylinder. This rotation increases the contact area and frequency with the rolling oil, promoting oil flow and accelerating the speed at which the oil passes through the first filtration system, thereby shortening the filtration time.

[0018] 2. The flange connection ensures the stability of the filter drum during operation, reduces equipment failure or leakage caused by loose connections, and allows for easy installation and removal of the filter drum from the through-hole shaft. The liquid-limiting outer cylinder restricts the flow range of liquid within the filter drum, allowing the liquid to pass more concentratedly through the filter drum and the first filter screen for filtration, preventing disorderly flow of liquid within the filter drum, reducing the residence time of liquid in non-filtration areas, thereby improving filtration efficiency. The liquid-limiting outer cylinder also provides some protection to the filter drum, reducing the direct impact of liquid on the filter drum.

[0019] 3. The agitator fan rotates synchronously with the second filter screen. The agitation of the agitator fan not only prevents oil sedimentation but also provides a certain auxiliary filtration effect on the oil on the second filter screen, promoting faster oil passage through the second filter screen and preventing the oil returning from the return oil line from impacting a single position for a long time, thus extending the service life of the second filter screen. This ensures that the returned oil is evenly distributed and participates in the filtration process again, improving the sufficiency and thoroughness of filtration.

[0020] 4. During rotation, the agitator fan stirs the oil, making the oil flow in the area more active. The return oil line can more effectively draw in the oil after preliminary filtration and agitation, improving the return oil efficiency. The toothed oil inlet can effectively prevent air stagnation, ensuring that the returned oil can participate in the subsequent filtration cycle in a timely manner. The clip can withstand a certain amount of vibration and impact, ensuring the stability of the oil inlet position of the return oil line and preventing the return oil function from being affected by loosening or displacement, thus improving the operational reliability of the equipment.

Detailed Implementation

[0027] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification. The present invention will be further described in detail below with reference to the accompanying drawings.

[0029] A rolling oil filtration device, such as Figures 1-5As shown, the system includes a filter cylinder, an oil inlet pipe 1, a first filtration system 2, and a second filtration system 3. A through-hole shaft 6 is rotatably mounted on the filter cylinder. The oil inlet pipe 1 is connected to one end of the through-hole shaft 6 via a rotary joint 7. The through-hole shaft 6 is connected to a first motor 5 via a bevel gear transmission component. The other end of the through-hole shaft 6 is connected to the first filtration system 2. The first filtration system 2 and the second filtration system 3 are installed sequentially from top to bottom inside the filter cylinder. The filter cylinder is provided with a return oil pipe 33. The oil inlet end of the return oil pipe 33 is connected to the filter cylinder, and the oil outlet end of the return oil pipe 33 is located between the first filtration system 2 and the second filtration system 3. The through-hole shaft 6 has a hollow through-hole at its center. An oil outlet pipe is also provided at the bottom of the filter cylinder. Both the oil outlet pipe and the return oil pipe are equipped with... There is an oil pump, and a through-hole shaft 6 passes through the top surface of the filter cylinder. A bearing is installed at the connection between the shaft and the top surface of the filter cylinder. The first motor 5 is located on the top surface of the filter cylinder. The small wheel end of the bevel gear transmission component is connected to the driving end of the first motor 5, while the large wheel end is keyed to the surface of the through-hole shaft 6. With the help of the rotary joint 7, the oil inlet pipe 1 avoids the rotational stress when the first motor 5 drives the through-hole shaft 6 to rotate, so as to avoid the stress affecting the oil inlet pipe 1. The flange part of the through-hole shaft 6 located in the inner cavity of the filter cylinder is connected to the filter rotating cylinder 21 in the first filtration system 2. The first filtration system 2 performs preliminary filtration of the rolling oil, and then further filtration is performed by the second filtration system 3. With the help of the return oil pipeline 33, the oil is filtered multiple times to achieve more thorough filtration.

[0030] like Figure 1 and Figure 5 As shown, the oil inlet of the return oil pipe 33 is toothed. The end of the return oil pipe 33 that abuts against the filter cylinder has a groove forming a regular or irregular tooth shape. The toothed oil inlet can serve as a gas escape channel, effectively preventing gas stagnation during oil suction and ensuring smooth oil flow. The oil inlet of the return oil pipe 33 is located on one side of the agitator fan 32. The oil inlet of the return oil pipe 33 is fixedly installed on the inner wall of the filter cylinder by a snap fastener. The snap fastener is preferably a plastic snap fastener. The return oil pipe 33 is a rigid oil suction pipe to prevent the stress generated when the agitator fan 32 agitates the oil from shaking the return oil pipe 33. The oil outlet of the return oil pipe 33 is located between the first filter screen 22 and the second filter screen 31. The snap fastener method of fixing the return oil pipe 33 makes the disassembly and installation of the oil inlet of the return oil pipe 33 convenient and quick. The staff can easily open the snap fastener to disassemble and maintain the return oil pipe 33 without having to disassemble the entire filter cylinder on a large scale, shortening maintenance time and reducing maintenance costs.

[0031] like Figure 2 and Figure 3 As shown, a sealing door 9 is opened on the side of the filter cartridge, and an observation window is opened on the sealing door 9, which makes it convenient for staff to observe the purity of the oil, determine whether to discharge, and visually observe whether the internal device needs to be cleaned and maintained.

[0032] like Figure 1 , Figure 3 and Figure 4As shown, the first filtration system 2 includes a filter cylinder 21 and a first filter screen 22. The filter cylinder 21 is flange-connected to the through-hole shaft 6. The flange connection ensures the stability of power transmission and facilitates the installation and disassembly of the filter cylinder 21. The first filter screen 22 is detachably installed on the filter cylinder below the filter cylinder 21. A through groove is opened on the side of the filter cylinder opposite to the sealing door 9. The first filter screen 22 can be pulled out and installed in the through groove for easy replacement. When the filter screen becomes clogged due to long-term use or the filtration effect decreases, it can be replaced in time to ensure the normal operation of the filtration system. A limiting liquid outer cylinder 4 is installed inside the filter cylinder. The liquid-limiting outer cylinder 4 is fitted onto the filter rotating cylinder 21. The filter rotating cylinder 21 rotates under the drive of the through-hole shaft 6. Centrifugal force is used to quickly throw out the oil to improve the filtration effect. During the rotation, under the action of centrifugal force and the internal structure of the filter rotating cylinder 21, the oil can quickly separate the larger particles of impurities. The liquid-limiting outer cylinder 4 can effectively limit the splash position of the oil thrown out from the filter rotating cylinder 21 and control it within a certain range. After the large particles are filtered, they drip into the first filter screen 22 for preliminary filtration. The first filter screen 22 performs secondary filtration on the oil to further remove the residual particulate impurities.

[0033] like Figure 1 As shown, the second filtration system 3 includes a second filter screen 31 and an agitator 32. The top surface of the agitator 32 is connected to the second filter screen 31 via a rotating shaft, and the bottom surface of the agitator 32 is connected to a second motor 8. The second filter screen 31 and the agitator 32 rotate synchronously under the drive of the second motor 8. The second filter screen 31 is shaped like a frustum, which increases the filtration area and improves the filtration efficiency. After the oil is filtered by the first filter screen 22, it drips onto the second filter screen 31. The rotation of the second filter screen 31 accelerates the filtration and penetration. The filtered oil accumulates at the bottom of the filter cylinder and is constantly agitated by the agitator 32 to prevent oil sedimentation. The oil drawn by the return oil pipe 33 flows back to the top surface of the second filter screen 31 for repeated filtration. Because the second filter screen 31 is rotating, the returned oil will not impact a single position of the second filter screen 31 for a long time, reducing filter damage. Instead, it is evenly distributed on the second filter screen 31 and participates in the filtration process again, further improving the filtration effect. The second motor 8 is embedded in the bottom of the filter cylinder, and the penetration is sealed with packing.

[0034] Working principle: A certain amount of rolling oil is introduced into the filter cylinder through the oil inlet pipe 1. At the same time, the operator starts the first motor 5 to make the filter drum 21 rotate. The oil in the filter drum 21 is thrown out by centrifugal force for the first step of filtration. The thrown-out oil drips onto the first filter screen 22 for the second step of filtration.

[0035] At the same time, the staff started the second motor 8, which made the agitator 32 and the second filter screen 31 rotate. At this time, the oil penetrated the first filter screen 22 and dripped onto the second filter screen 31. The second filter screen 31 rotated to accelerate the filtration and penetration, completing the third step of filtration. The agitation of the agitator 32 at the bottom made the rolling oil flow. At this time, it was filtered again through the return oil pipeline 33.

[0036] Staff members observe the filtration rate of the rolling oil through the observation window, and then discharge the filtered rolling oil through the oil outlet pipe.

The contents not described in detail in this specification are prior art known to those skilled in the art.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields.
