Description

Technical Field

[0001] This utility model relates to the field of measuring tube cleaning technology, and in particular to a cleaning device for cleaning lubricating oil viscosity measuring tubes using petroleum ether cleaning agent. Background Technology

[0002] Currently, there are two types of instruments for measuring the viscosity of lubricating oil: manual instruments and automatic instruments. Automatic instruments can automatically record the flow time of lubricating oil, and by setting the corresponding viscosity tube coefficient in the instrument parameters, the viscosity of the corresponding sample can be automatically analyzed.

[0003] In the field of lubricating oil quality testing, lubricating oil viscosity measurement is a key indicator test item. As an important instrument for this test, the cleanliness of the lubricating oil viscosity measuring tube has a direct impact on the accuracy of the test results.

[0004] Currently, the test tubes require five cleaning cycles with petroleum ether, each consuming 40 ml of petroleum ether. Each cleaning cycle involves automatically drawing fresh analytical grade petroleum ether solvent, resulting in a significant consumption of petroleum ether. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a cleaning device for cleaning a lubricating oil viscosity measuring tube using petroleum ether cleaning agent, which can overcome the above problems or at least partially solve the above problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A cleaning device for cleaning lubricating oil viscosity measuring tubes using petroleum ether cleaning agent includes: a cleaning platform; a cleaning tank disposed on the upper side of the cleaning platform; a storage tank, a circulation tank, and a collection tank disposed within the cleaning platform; a controller disposed within the cleaning platform; a feed pump disposed on the cleaning platform; a first extraction pipe disposed between the storage tank and the feed pump; a second extraction pipe disposed between the circulation tank and the feed pump; a first connecting assembly disposed between the feed pump and the lubricating oil viscosity measuring tube body; an extraction pump disposed on the cleaning platform; a second connecting assembly disposed between the extraction pump and the lubricating oil viscosity measuring tube body; a first discharge pipe disposed between the extraction pump and the collection tank; a second discharge pipe disposed between the circulation tank and the extraction pump; an opening / closing door disposed on one side of the cleaning platform; and a first sealing plug for sealing the lubricating oil viscosity measuring tube body.

[0008] Furthermore, the first connecting assembly includes a second sealing plug disposed at one end of the lubricating oil viscosity measuring tube body, and a feeding pipe is disposed between the second sealing plug and the feeding pump. The second connecting assembly includes a third sealing plug disposed at the other end of the lubricating oil viscosity measuring tube body, and a connecting pipe is disposed between the third sealing plug and the pump.

[0009] Preferably, the feed pipe is provided with an air supply pipe.

[0010] To prevent any residue from remaining inside the lubricating oil viscosity measuring tube, a purifier is fixedly connected to one side of the cleaning station. The exhaust end of the purifier is connected to the air supply pipe, and an air extraction pipe is provided on one side of the purifier.

[0011] To facilitate the installation of the lubricating oil viscosity measuring tube body, the cleaning tank is further provided with a mounting bracket corresponding to the lubricating oil viscosity measuring tube body.

[0012] To further improve the cleaning effect on the lubricating oil viscosity measuring tube body, an ultrasonic vibration table is further provided inside the cleaning table, and the ultrasonic vibration table is fixedly connected to the mounting frame.

[0013] Compared with the prior art, this utility model provides a cleaning device for cleaning lubricating oil viscosity measuring tubes using petroleum ether cleaning agent, which has the following beneficial effects:

[0014] 1. This cleaning device uses petroleum ether cleaning agent to clean lubricating oil viscosity measuring tubes. When cleaning the first lubricating oil viscosity measuring tube, the controller closes the solenoid valve in the second extraction pipe and opens the solenoid valve in the first extraction pipe. At this time, the feed pump draws clean petroleum ether cleaning agent from the storage tank and delivers it to the lubricating oil viscosity measuring tube for the first cleaning. The cleaning liquid is then extracted by the extraction pump. During the first cleaning, waste liquid is delivered to the collection tank through the first discharge pipe, and waste liquid from the second to fifth cleanings is delivered to the circulation tank through the second discharge pipe. When cleaning the second lubricating oil viscosity measuring tube, liquid is drawn from the circulation tank through the second extraction pipe and delivered to the lubricating oil viscosity measuring tube for cleaning. The first three cleanings use liquid from the circulation tank, while the fourth and fifth cleanings use clean petroleum ether cleaning agent drawn from the storage tank through the first extraction pipe. This waste liquid utilization cleaning method greatly reduces the amount of petroleum ether cleaning agent used, saving cleaning costs and reducing environmental pollution.

[0015] 2. The cleaning device that uses petroleum ether cleaning agent to clean the lubricating oil viscosity measuring tube, after completing five cleaning cycles, controls the feed pump to shut off, and then controls the purifier and the solenoid valve in the air supply pipe to open, so that clean gas passes through the body of the lubricating oil viscosity measuring tube, thereby effectively preventing petroleum ether cleaning agent residue inside and facilitating its initial drying.

[0016] 3. The cleaning device that uses petroleum ether cleaning agent to clean the lubricating oil viscosity measuring tube can improve the cleaning effect on the body of the lubricating oil viscosity measuring tube by using an ultrasonic vibration table.

[0017] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model can greatly reduce the amount of petroleum ether cleaning agent used by using waste liquid cleaning, which saves cleaning costs and reduces environmental pollution, and can also improve the cleaning effect on the body of the lubricating oil viscosity measuring tube.

[0023] 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.

[0024] Example 1: Refer to Figures 1-4 A cleaning device for cleaning a lubricating oil viscosity measuring tube using petroleum ether cleaning agent includes: a cleaning platform 1, and a cleaning tank 101 disposed on the upper side of the cleaning platform 1; a storage tank 6, a circulation tank 601, and a collection tank 602 disposed inside the cleaning platform 1; a controller 105 disposed inside the cleaning platform 1; a feed pump 3 disposed on the cleaning platform 1; a first extraction pipe 301 disposed between the storage tank 6 and the feed pump 3; a second extraction pipe 302 disposed between the circulation tank 601 and the feed pump 3; a first connecting assembly disposed between the feed pump 3 and the lubricating oil viscosity measuring tube body 2; an extraction pump 5 disposed on the cleaning platform 1; a second connecting assembly disposed between the extraction pump 5 and the lubricating oil viscosity measuring tube body 2; a first discharge pipe 501 disposed between the extraction pump 5 and the collection tank 602; a second discharge pipe 502 disposed between the circulation tank 601 and the extraction pump 5; an opening / closing door 104 disposed on one side of the cleaning platform 1; and a first sealing plug 201 for sealing the lubricating oil viscosity measuring tube body 2.

[0025] The first connecting assembly includes a second sealing plug 304 disposed at one end of the lubricating oil viscosity measuring tube body 2, and a feeding pipe 303 disposed between the second sealing plug 304 and the feeding pump 3. The second connecting assembly includes a third sealing plug 504 disposed at the other end of the lubricating oil viscosity measuring tube body 2, and a connecting pipe 503 disposed between the third sealing plug 504 and the pump 5.

[0026] An air supply pipe 402 is installed on the feed pipe 303.

[0027] When cleaning the lubricating oil viscosity measuring tube body 2, five cleaning cycles are generally performed. During the first cleaning of the lubricating oil viscosity measuring tube body 2, the controller 105 controls the solenoid valve in the second extraction pipe 302 to close and the solenoid valve in the first extraction pipe 301 to open. At this time, the feed pump 3 draws clean petroleum ether cleaning agent from the storage tank 6 and delivers it to the lubricating oil viscosity measuring tube body 2 for the first cleaning. The cleaning liquid is then extracted by the extraction pump 5. During the first cleaning, waste liquid is transported to the collection tank 602 through the first discharge pipe 501 and discharged through the second discharge pipe 502. The waste liquid from the second to fifth cleaning cycles is transported to the circulation tank 601. When cleaning the second lubricating oil viscosity measuring tube body 2, the liquid in the circulation tank 601 is drawn through the second extraction pipe 302 and transported to the lubricating oil viscosity measuring tube body 2 for cleaning. The first three cleaning cycles use the liquid in the circulation tank 601. The fourth and fifth cleaning cycles use clean petroleum ether cleaning agent drawn from the storage tank 6 through the first extraction pipe 301. By using waste liquid for cleaning, the amount of petroleum ether cleaning agent used can be greatly reduced, which saves cleaning costs and reduces environmental pollution.

[0028] It should be noted that solenoid valves are installed in the first extraction pipe 301, the second extraction pipe 302, the first discharge pipe 501, the second discharge pipe 502, and the air supply pipe 402.

[0029] Example 2: Refer to Figures 1-4 A cleaning device for cleaning a lubricating oil viscosity measuring tube using petroleum ether cleaning agent is basically the same as in Example 1. Further, a purifier 4 is fixedly connected to one side of the cleaning platform 1, the exhaust end of the purifier 4 is connected to the air supply pipe 402, and an exhaust pipe 401 is provided on one side of the purifier 4.

[0030] In a specific implementation, after five cleaning cycles are completed, the feed pump 3 is shut off by the controller 105, and then the solenoid valves in the purifier 4 and the air supply pipe 402 are opened by the controller 105, so that clean gas passes through the lubricating oil viscosity measuring tube body 2, thereby effectively preventing petroleum ether cleaning agent residue inside and facilitating its initial drying.

[0031] The cleaning tank 101 is equipped with a mounting bracket 103 corresponding to the body 2 of the lubricating oil viscosity measuring tube.

[0032] An ultrasonic vibration table 102 is installed inside the cleaning station 1, and the ultrasonic vibration table 102 is fixedly connected to the mounting bracket 103.

[0033] The ultrasonic vibration table 102 can improve the cleaning effect on the lubricating oil viscosity measuring tube body 2.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
