Description

[0001] The utility model relates to the technical field of lubricating oil production, in particular to a lubricating oil production inspection device. Background Art

[0002] Viscosity is an important parameter to measure the flow resistance of lubricating oil. Generally, viscosity is inversely proportional to temperature. As temperature rises, viscosity decreases, and as temperature decreases, viscosity increases. Therefore, in the production process of lubricating oil, it is often necessary to measure the absolute viscosity of lubricating oil with a rotational viscometer.

[0004] According to the existing technical literature, the test platform can heat the lubricating oil to different temperatures through a heating mechanism, and then test the lubricating oil at different temperatures through a viscosity testing mechanism. However, the liquid storage tank containing the heated lubricating oil to be tested is horizontally displaced by the cooperation of a movable plate and a screw. After moving to the bottom of the viscometer and completing the viscosity test, the lubricating oil in the liquid storage tank cannot be automatically poured out, and the lubricating oil needs to be manually poured out to continue the viscosity test.

[0005] To this end, the utility model optimizes and improves the problem in the prior art that it is inconvenient to dump the lubricating oil after the detection is completed. Hereby, a new device is proposed which can automatically complete the detection of lubricating oil at different temperatures through an intermittent structure and can realize automatic dumping and cleaning of the lubricating oil, so as to better solve the problems in the prior art.

DETAILED DESCRIPTION

[0028] The following is a detailed description of the embodiments of the technical solution of the utility model in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the scope of protection of the utility model. Figure 1-Figure 4 as shown in .

[0029] A lubricating oil production inspection device comprises a fixedly installed heating tank 1, on the left and right outer walls of the heating tank 1, heating plates 2 for plugging in are respectively attached and fixedly connected, an oil outlet pipe 3 is fixedly plugged into the mounting hole at the bottom of the heating tank 1 and the two are internally connected, a solenoid valve 4 is provided in the middle of the oil outlet pipe 3, a detector 5 is provided on the right side of the heating tank 1, an intermittent conveying structure with clockwise rotation is provided below the heating tank 1 and the detector 5, a plurality of container assemblies for containing lubricating oil are evenly spaced around the periphery of the intermittent conveying structure, a liquid collecting pool 6 is provided below the right end of the intermittent conveying structure, a water inlet pipe 7 is provided on the left side of the liquid collecting pool 6, a nozzle 9 is fixedly connected to the right end of the water inlet pipe 7 and the two are internally connected, the nozzle 9 is arranged in the space between the liquid collecting pool 6 and the container assembly at the corresponding position, a hot air pipe 8 is provided below the left end of the intermittent conveying structure, and the right end of the hot air pipe 8 is arranged below the container assembly at the corresponding position.

[0030] The heating tank 1 is fixedly suspended and has a feed port 28 on one side of its top for adding lubricating oil into the interior thereof. Heating plates 2 are fitted on the left and right outer walls thereof. The heating plates 2 are connected to a power source to heat the lubricating oil in the inner cavity of the heating tank 1 to different temperatures. The opening and closing of the oil outlet pipe 3 can be controlled by the solenoid valve 4. After the lubricating oil is heated, the solenoid valve 4 is opened to take out a certain amount of lubricating oil through the oil outlet pipe 3.

[0031] The number of container assemblies is six, and they are evenly spaced at fixed intervals on the intermittent conveying structure. The intermittent conveying structure is controlled by the existing program to intermittently rotate in the clockwise direction, thereby driving each container assembly to rotate in the clockwise direction in an intermittent manner. The left end of the water inlet pipe 7 is connected to the external water tank through a pump, and then the clean water in the water tank is sprayed out through the nozzle 9. The left end of the hot air pipe 8 is connected to the external fan, and the inhaled air is heated by the existing heating mechanism, so that high-temperature air is blown out at the right end of the hot air pipe 8.

[0032] When the intermittent conveying structure stops moving, two container assemblies remain on its upper side and are respectively located directly below the lower end opening of the oil outlet pipe 3 and directly below the lower end rotor of the detector 5. At this time, the lubricating oil heated in the heating tank 1 is injected into the container assembly at the upper left end through the oil outlet pipe 3, and at the same time, the rotor at the lower end of the detector 5 can extend into the container assembly at the upper right end to complete the viscosity detection work.

[0033] A container assembly is respectively placed at the left and right ends of the intermittent conveying structure. The container assembly at the right end is tilted so that the lubricating oil inside it is poured into the liquid collection tank 6, and the container assembly at the left end waits for the next oil filling and completes subsequent operations one by one.

[0034] Two container assemblies are parked on the lower side of the intermittent conveying structure and are respectively located directly above the water outlet of the nozzle 9 and directly above the air outlet of the hot air pipe 8. At this time, the container assembly at the right end of the lower side can be cleaned under the action of the water spray of the nozzle 9, and the container assembly at the left end of the lower side can be dried under the action of the hot air pipe 8.

[0035] In this way, each container component can complete the oil filling, testing, oil pouring, cleaning and drying operations in sequence under the intermittent cooperation of the intermittent conveying structure, and the entire operation process is cycled through the rotational movement of the intermittent conveying structure.

[0036] A plurality of legs 27 are fixed on the top of the liquid collecting tank 6 to support it and prevent the liquid collecting tank 6 from rusting.

[0037] In any of the above schemes, it is preferred that the intermittent conveying structure includes two mounting beams 10 that are spaced apart and fixed in the horizontal direction, a plurality of driving members are spaced apart along the length direction in the space between the two mounting beams 10, a chain transmission group is connected around each of the driving members, and each of the container assemblies is evenly spaced and installed at a corresponding position of the chain transmission group.

[0038] The two mounting beams 10 are fixedly arranged by a plurality of support frames 26, and the driving members are movably installed between the two mounting beams 10. Through the rotation and stopping of the driving members, the chain transmission group can rotate intermittently, thereby driving the container components to rotate synchronously and intermittently, so as to complete the oil filling, detection, oil pouring, cleaning and drying operations in sequence.

[0039] In any of the above schemes, it is preferred that the driving member includes a rotating shaft 11, both ends of which are movably inserted into the rotating holes on the mounting beam 10 at corresponding positions, and two sprockets 12 are provided in the middle section of the rotating shaft 11 at intervals along its length direction and coaxially fixedly sleeved, and the two sprockets 12 are respectively arranged close to the inner side of the mounting beam 10 at corresponding positions, and the two sprockets 12 are respectively meshed and connected with the corresponding positions of the chain transmission group.

[0040] The rotating shaft 11 is connected to the bearing on the mounting beam 10 by a key connection, so as to realize the free rotation of the rotating shaft 11. At the same time, the two sprockets 12 are connected to the rotating shaft 11 by a key connection, so as to drive the two sprockets 12 to rotate synchronously. Since the two sprockets 12 are respectively meshed with the corresponding positions of the chain transmission group, the chain transmission group can drive each container assembly to rotate intermittently under the drive of the two sprockets 12.

[0041] In any of the above schemes, it is preferred that the chain transmission group includes two chains 13 arranged at intervals, and the two chains 13 are respectively arranged around the sprockets 12 on the corresponding sides, the upper layers of the two chains 13 are respectively meshed with the teeth on the top of the sprockets 12 at the corresponding positions, and the lower layers of the two chains 13 are respectively meshed with the teeth on the bottom of the sprockets 12 at the corresponding positions, and the two ends of the bottom of each container assembly are respectively installed on the inner side of the corresponding positions of the two chains 13.

[0042] The two chains 13 are respectively arranged at the two ends of the rotating shaft 11, so as to be meshed and connected with the sprockets 12 on the corresponding sides. In this way, when the rotating shaft 11 rotates and thus drives the corresponding sprockets 12 to rotate, under the meshing cooperation of the sprockets 12 and the chains 13, the two chains 13 can be further driven to rotate synchronously and intermittently in the clockwise direction, thereby ultimately causing each container assembly to intermittently move.

[0043] In any of the above schemes, preferably, the container assembly includes a mounting plate 14 arranged along the length direction of the rotating shaft 11, a cup body 15 is fixedly connected to the middle of the outer plate surface of the mounting plate 14, and connecting plates 16 are respectively fixedly connected to both ends of the inner plate surface of the mounting plate 14, and the two connecting plates 16 are respectively arranged near the inner sides of the corresponding positions of the two chains 13;

[0044] Two through holes are spaced apart on the connecting plate 16 , and inner ends of two adjacent pins 29 of the chain 13 at corresponding positions are movably inserted into the through holes of the connecting plate 16 .

[0045] The utility model arranges the connecting plate 16 on the inner side of the corresponding position of the chain 13, and at the same time, the inner ends of the two pins 29 on the outer link plate at that position are respectively movably inserted into the corresponding through holes of the connecting plate 16, so that the two connecting plates 16 are respectively installed on the inner sides of the two chains 13. At the same time, since the spacing between the two adjacent pins 29 on the same outer link plate of the chain 13 is fixed, when the two chains 13 are meshed or bent, the two connecting plates 16 will not interfere with the movement of the chains 13.

[0046] In this way, the mounting plate 14 can be fixedly mounted at the corresponding position between the two chains 13 through the two connecting plates 16 , thereby fixing the cup body 15 for containing lubricating oil, and at the same time, each cup body can be synchronously intermittently rotated with the two chains 13 .

[0047] In any of the above schemes, preferably, a motor 17 is fixedly provided above the heating tank 1, the motor shaft of the motor 17 is vertically downward and coaxially fixedly connected with a rotating rod 18, the lower end of the rotating rod 18 is movably inserted into the rotating hole at the top of the heating tank 1 and extends into the inner cavity thereof, and a plurality of blades 19 are fixedly connected at intervals at the lower part of the rotating rod 18 along its length direction.

[0048] The motor 17 is fixedly installed above the heating tank 1 through a motor frame, and the motor shaft is coaxially connected to the rotating rod 18 through a coupling. The rotating rod 18 passes through the sealing hole on the top of the heating tank 1 so that the lower part with the blades 19 fixedly connected is extended into the inner cavity of the heating tank 1. In this way, driven by the motor 17, the rotating rod 18 rotates, and then drives each blade 19 to rotate, thereby stirring the lubricating oil in the inner cavity of the heating tank 1, so that the lubricating oil can be evenly heated under the heating action of the heating plate 2.

[0049] In any of the above schemes, preferably, a top plate 20 is provided above the heating tank 1 and the detector 5, the heating tank 1 is fixedly mounted on the bottom of the left end of the top plate 20 through a connecting frame 21, and the detector 5 is fixedly mounted on the bottom of the right end of the top plate 20 through a plurality of electric cylinders 22.

[0050] The heating tank 1 is fixedly suspended on the left end of the top plate 20 by the connecting frame 21, and the detector 5 is fixedly suspended on the right end of the top plate 20 by two electric cylinders 22. At the same time, under the action of the electric cylinders 22, the detector 5 can move up and down, so that its rotor can extend into the corresponding cup body 15 and move out of the cup body 15.

[0051] In any of the above solutions, preferably, one end of the rotating shaft 11 on the left side passes through the rotating hole of the mounting beam 10 at the corresponding position and is coaxially fixedly sleeved with a pulley 23.

[0052] One end of the leftmost rotating shaft 11 passes through the bearing shaft hole on the corresponding mounting beam 10, and is thereby coaxially fixedly connected to the pulley 23 by means of a key connection. The pulley 23 is connected to an external driving motor by a belt, so that the pulley 23 and the corresponding rotating shaft 11 can be driven to rotate by means of a belt transmission, and then linkage is achieved through the engagement of each sprocket 12 and the two chains 13, thereby ultimately achieving intermittent rotation of each cup body 15.

[0053] In any of the above solutions, preferably, a drain pipe 24 is fixedly inserted into the mounting hole at the lower part of the left side wall of the liquid collecting tank 6 and the two are internally connected.

[0054] The drain pipe 24 is provided to facilitate the discharge of the water-oil mixture in the liquid collecting tank 6 .

[0055] In any of the above solutions, preferably, a filter screen 25 is fixedly installed at the right end of the hot air pipe 8 .

[0056] The filter 25 can filter out the particle residue in the air, ensuring that the cup body 15 will not be polluted when being dried.

[0057] Specific working principle:

[0058] The pulley 23 mounted on the end of the rotating shaft 11 is driven by an external driving motor in the form of a belt drive, and the external driving motor is controlled to work intermittently through the existing program, so that the rotating shaft 11 and the corresponding two sprockets 12 are rotated intermittently accordingly, and under the meshing cooperation between each sprocket 12 and the corresponding chain 13, the connecting plate 16 and the mounting plate 14 are fixedly installed, and finally each cup body 15 is rotated intermittently in the clockwise direction.

[0059] Before officially starting the detection work, the lubricating oil to be tested is first added to the heating tank 1 through the feed port 28, and then the heating tank 1 is heated by the heating plate 2. At the same time, the motor 17 drives the blades 19 on the rotating rod 18 to rotate, so that the lubricating oil in the heating tank 1 is heated to different temperatures.

[0060] During the working process, each cup body 15 moves intermittently. When it is in the intermittent state, the solenoid valve 4 is opened and the heated lubricating oil is injected into the cup body 15 directly below it through the oil outlet pipe 3. Then the corresponding cup body 15 moves and shifts to the bottom of the detector 5 and enters the intermittent state again. At the same time, under the action of the electric cylinder 22, the detector 5 moves downward so that the rotor extends into the cup body 15 and completes the detection work. After the electric cylinder 22 drives the detector 5 to move upward, the cup body 15 continues to move and shift. When it moves to the right end bend of the chain 13, the device enters the intermittent state again. In the intermittent state, the cup body 15 is tilted to pour the lubricating oil inside into the liquid collecting pool 6 below it, and then the cup body 15 continues to move to the top of the nozzle 9. Under the effect of the cup body 15 in the intermittent state, there is sufficient time to spray water to clean the cup body 15, and then continue to move to the top of the hot air pipe 8. The corresponding cup body 15 is dried by the hot air pipe 8 during the interval time period. The dried cup body 15 continues to move to the left end bend of the chain 13 and waits for the next oil filling, inspection, oil pouring, cleaning and drying operation process.

[0061] During the continuous intermittent movement of each cup body 15, the heating plate 2 continuously heats the heating tank 1, so that the lubricating oil inside it can be continuously heated and the temperature continues to rise. In this way, with the cooperation of the overall device, each cup body 15 can automatically complete the viscosity detection of the lubricating oil at different temperatures in turn.

[0062] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, and these changes and improvements fall within the scope of the utility model to be protected.
