Description

Technical Field

[0001] This utility model relates to the field of thin oil station technology, specifically to an environmentally friendly thin oil station oil impurity separation device. Background Technology

[0002] The working principle of a thin oil station is to force lubricating oil to the friction parts of the equipment, forming an oil film between the relatively moving machine parts, thereby reducing friction and wear, and carrying away the heat generated by friction.

[0003] The Chinese utility model patent with authorization announcement number CN221705170U discloses an anti-clogging high and low pressure thin oil station, which pressurizes the lubricating oil in the oil tank through a pressurizing pump to a three-way filter valve. The three-way filter is equipped with a filter screen, which filters the lubricating oil. The filtered impurities enter the circulation mechanism through the other end of the three-way valve, and after secondary filtration by the circulation mechanism, they return to the oil tank for recycling.

[0004] However, the filtration capacity of the internal filter screen of the three-way filter valve is very limited. After a period of use, impurities tend to stick to one side of the filter screen, causing blockage and requiring frequent disassembly and cleaning of the three-way filter valve. Utility Model Content

[0005] The purpose of this invention is to propose an environmentally friendly oil impurity separation device for thin oil stations, which solves the problem of the need for frequent disassembly and cleaning of filter screens in existing thin oil stations.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an environmentally friendly thin oil station oil impurity separation device, including a thin oil station tank, a pump installed in the thin oil station tank, an outlet pipe connected to the outlet of the pump, the outlet pipe being connected to the lubricant inlet of mechanical equipment, an inlet pipe installed in the thin oil station tank, the inlet pipe being connected to the lubricant outlet of the mechanical equipment, a first filter device installed between the outlet pipe and the lubricant inlet of the mechanical equipment, and a second filter device connected between the outlet pipe and the thin oil station tank; The first filtration device includes a fixed shell with one side fixed to the liquid outlet pipe, and the other side of the fixed shell is used to connect to the lubricant inlet of the mechanical equipment. The fixed shell has a cylindrical cavity inside, and a cylindrical rotating block is rotatably installed inside the cavity. A through hole is provided on the side of the rotating block, and a filter screen is fixed inside the through hole. A motor is fixed at the upper end of the fixed shell, and the output shaft of the motor is fixedly connected to the upper end of the rotating block to drive the rotating block to rotate in the cavity and adjust the orientation of the filter screen. A valve is installed between the fixed housing and the lubricant inlet of the mechanical equipment, and the inlet of the second filter device is connected between the fixed housing and the inlet of the valve.

[0007] Compared with the prior art, the beneficial effects of this utility model are as follows: This utility model is an environmentally friendly thin oil station oil impurity separation device. Through the design of a motor-driven rotary filter screen and backwashing pipeline, when the filter screen is blocked on one side, only the valve needs to be manually operated and the motor controlled to rotate the filter screen. The system oil pressure can be used to backwash the filter screen. Compared with the prior art, the filter device can be cleaned without disassembly, which significantly reduces maintenance downtime and manual cleaning workload. Attached Figure Description

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figure 1-6This utility model discloses an environmentally friendly thin oil station oil impurity separation device, comprising a thin oil station tank 1, a pump 4 installed in the thin oil station tank 1, the inlet of the pump 4 being connected to the interior of the thin oil station tank 1, and an outlet pipe 5 connected to the outlet of the pump 4, which is used to connect to the lubricating fluid inlet of mechanical equipment, for delivering the lubricating oil in the thin oil station tank 1 to the friction parts of the mechanical equipment for lubrication. The thin oil station tank 1 is also equipped with an inlet pipe 8, which is used to connect to the lubricating fluid outlet of the mechanical equipment, for recovering the lubricating oil from the friction parts of the mechanical equipment back into the interior of the thin oil station tank 1 through the inlet pipe 8. A first filter device 7 is installed between the outlet pipe 5 and the lubricating fluid inlet of the mechanical equipment, and a second filter device 11 is connected between the outlet pipe 5 and the thin oil station tank 1. The first filter device 7 is used to filter impurities to prevent impurities from entering the interior of the mechanical equipment, and the second filter device 7 is used to collect the impurities filtered out by the first filter device 7.

[0016] The above describes existing technology, which will not be detailed here. The principle can be found in the anti-clogging high and low pressure thin oil station disclosed in Chinese Utility Model Patent No. CN221705170U, which will not be elaborated upon here. It is understandable that the filters used in existing thin oil stations for filtering impurities require frequent disassembly for cleaning, making them cumbersome to use. To solve this problem, the main innovation of this utility model based on existing technology lies in: The first filtration device 7 includes a fixed housing 74 fixed to the outlet pipe 5 on one side. The fixed housing 74 can be a cylindrical structure. The other side of the fixed housing 74 is used to connect to the lubricant inlet of the mechanical equipment. The interior of the fixed housing 74 is provided with a cylindrical cavity 73, which communicates with the interior of the outlet pipe 5. A cylindrical rotating block 75 is rotatably mounted inside the cavity 73. Figure 4 The diagram shows a top view of the installation structure of the rotating block 75. The side of the rotating block 75 is provided with a through hole 77, and a filter screen 76 is fixed inside the through hole 77. A motor 71 is fixed at the upper end of the fixed shell 74. The output shaft of the motor 71 is fixedly connected to the upper end of the rotating block 75 and is used to drive the rotating block 75 to rotate in the cavity 73 and adjust the orientation of the filter screen 76.

[0017] A valve 9 is installed between the fixed housing 74 and the lubricant inlet of the mechanical equipment. The valve 9 can be a manual butterfly valve. The inlet of the second filter device 11 is connected between the fixed housing 74 and the inlet of the valve 9.

[0018] In use, the lubricating oil in the thin oil station tank 1 enters the outlet pipe 5 through the outlet of pump 4, and then enters the fixed housing 74 through the outlet pipe 5. After entering the fixed housing 74, it enters the interior of the rotating block 75 through one end of the through hole 77, is filtered by the filter screen 76, and then exits the fixed housing 74 through the other end of the through hole 77 and enters the interior of the mechanical equipment. Over time, the filter screen 76... Figure 2 , Figure 3 as well as Figure 5 As shown, impurities on the left side will gradually increase. At this time, valve 9 can be closed, and motor 71 can drive rotating block 75 to rotate 180°, changing the orientation of filter screen 76. Then, pump 4 is started, and high-pressure lubricating oil is used to backwash the impurities on the surface of filter screen 76. The impurities that are washed down will all enter the second filter device 11, thereby extending the service life of filter screen 76 and avoiding frequent disassembly and cleaning.

[0019] In some embodiments, the fixed housing 74 is connected to the liquid outlet pipe 5 via the flange structure 12, which facilitates the disassembly of the first filter device 7.

[0020] To ensure the sealing effect between the rotating block 75 and the inner wall of the cavity 73, a first sealing gasket 78 is fixed to the side of the rotating block 75, and a second sealing gasket 72 is fixed to the top and bottom of the rotating block 75.

[0021] It also includes a control system, which comprises a controller 2 fixed to the thin oil tank 1 and a pressure sensor 6 fixed to the outlet pipe 5. Both the controller 2 and the pressure sensor 6 adopt existing structures. For example, the controller 2 can be a conventional programmable PLC controller, such as the Siemens S7-200 series, and the pressure sensor 6 can be a commonly used industrial resistive or capacitive pressure transmitter, such as the PT124B-111 pressure sensor. The signal output terminal of the pressure sensor 6 is electrically connected to the signal input terminal of the controller 2, and the signal output terminal of the controller 2 is electrically connected to the signal input terminal of the motor 71. In some embodiments, the signal output terminal of the controller 2 is also connected to the signal input terminal of the LED light 12. At the inlet, LED light 12 is fixed on the surface of the thin oil station tank 1. During use, pressure sensor 6 is used to monitor the pressure value of lubricating oil. When the pressure value is abnormal, it indicates that a blockage has occurred. After receiving the signal, controller 2 controls LED light 12 to light up, reminding the staff to handle the situation. After receiving the warning, the staff can manually close valve 9 to temporarily cut off the oil supply to the mechanical equipment, and start motor 71 and pump 4 through controller 2 to turn the side of the blocked filter screen 76 toward the inlet direction of the second filter device 11. The high-pressure lubricating oil pumped by pump 4 performs a reverse flushing, and the impurities flushed down enter the second filter device 11 and are collected. The entire process does not require disassembling filter screen 76, which greatly extends the maintenance cycle.

[0022] The upper end of the oil tank 1 of the thin oil station is provided with a filling port 3, and the opening of the filling port 3 can be connected to the cover by means of threaded connection.

[0023] The second filtration device 11 includes a connecting pipe 10 connecting the liquid outlet pipe 5 and the thin oil station tank 1, and a filter installed on the connecting pipe 10. The connecting pipe 10 can be equipped with a control valve, which can be an electrically controlled valve or a manual valve. When the control valve is an electrically controlled valve, its signal input terminal is connected to the signal input terminal of the controller 2.

[0024] The filter has a tank structure with a cover at the top. The cover and the tank can be connected by a flange, and the cover is connected to the connecting pipe 10 to introduce lubricating oil into the tank. The tank is equipped with a filter element to filter and collect impurities, which will not be described in detail here.

[0025] The connection methods of the above electrical components are all conventional technical means in this field. For specific wiring and configuration, please refer to the corresponding product manual or common knowledge in this field. They will not be elaborated here.

[0026] This invention features a 180-degree rotatable filter screen 76 driven by a motor 71 within the first filtration device 7. When the pressure sensor 6 detects blockage in the filter screen 75, the controller 2 receives a signal and controls the LED light 12 to illuminate, alerting staff to address the issue promptly. During the process, staff can manually close the valve 9 and control the motor 71 via the controller 2 to rotate the rotating block 75, causing the filter screen 76 to rotate and change its orientation. A pump 4 then pumps high-pressure lubricating oil into the fixed housing 74 to backwash the original blockage surface of the filter screen 76. The dislodged impurities are collected along with the lubricating oil in the second filtration device 11, effectively solving the problem of frequent disassembly and cleaning required for traditional thin oil station filtration devices.

[0027] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.

[0028] 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.
