[0033] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. It should be noted that, unless otherwise specified, the embodiments and features in the embodiments of this application can be arbitrarily combined with each other.
[0034] The processing of fibers (such as carbon fiber) includes a drying step, which is usually completed by a drying drum. During the operation of the drying drum, its bearings need to be lubricated and cooled. Lubricating oil can be divided into dry oil and thin oil according to its viscosity. In related technologies, dry oil is usually used to lubricate the bearings of the drying drum, which requires frequent replenishment of grease. This is not only expensive, but also prone to gelling and clumping.
[0035] To address the aforementioned issues, this application provides an automatic lubrication device. Lubricating oil in the clean oil chamber enters the bearing housing through the oil outlet pipe, allowing sufficient time for contact with the bearing to lubricate it and remove heat. It then flows through the return oil pipe into the oil storage chamber, and after filtration and cooling by the cooling and filtering system, returns to the clean oil chamber, forming a cycle that saves raw material costs and improves cooling efficiency. Due to the improved cooling effect, the lubricating oil in this application can be thin oil, eliminating the need for grease and reducing the likelihood of clumping. This allows for long-term cyclical use, significantly reducing production costs. Furthermore, by incorporating sensors and a controller, the controller adjusts the equipment in real-time based on parameters detected by the sensors, ensuring normal operation and saving labor costs.
[0036] The automatic lubrication device provided in accordance with this application will now be described in detail with reference to the accompanying drawings.
[0037] It should be noted that, Figures 1 to 3 In this diagram, the x-axis and y-axis are both horizontal, while the z-axis is vertical; additionally... Figure 1 and Figure 2 The drying drum 30 in the figure is only used as an example. The automatic lubrication equipment provided in this application can also lubricate the bearings of other devices. The figure above does not constitute a limitation on the scope of use of the automatic lubrication equipment in this application.
[0038] An exemplary embodiment of this application provides an automatic lubrication device, such as... Figures 1 to 3 As shown, the automatic lubrication equipment includes a housing 100, an oil outlet pipeline system, an oil return pipeline system, and a cooling and filtration system. The housing 100 is used to store lubricating oil. A partition 130 is provided inside the housing 100, which divides the space inside the housing 100 into an oil storage chamber 110 and a clean oil chamber 120. The oil storage chamber 110 and the clean oil chamber 120 are connected through a cooling and filtration system provided outside the housing 100, but they are not connected inside the housing 100. The cooling and filtration system is used to filter and cool the lubricating oil in the oil storage chamber 110 and then deliver it to the clean oil chamber 120.
[0039] The oil outlet pipeline includes at least one oil outlet pipe 210, which connects the clean oil chamber 120 and the inlet 11 of the bearing housing. The oil return pipeline includes at least one oil return pipe 310, which connects the outlet 12 of the bearing housing and the oil storage chamber 110. In this embodiment, since there are two bearings, the oil outlet pipe 210 includes a first oil outlet pipe 2110 and a second oil outlet pipe 2120. The oil return pipe 310 includes a first oil return pipe 3110 and a second oil return pipe 3120. After the lubricating oil enters the first bearing housing 10 through the first oil outlet pipe 2110, it returns to the oil storage chamber 110 through the first oil return pipe 3110. In addition, the lubricating oil also enters the second bearing housing 20 through the second oil outlet pipe 2120 and returns to the oil storage chamber 110 through the second oil return pipe 3120. In other embodiments, the number of oil outlet pipes 210 can be three, four, etc., and the number of oil return pipes 310 can be three, four, etc. The number of oil outlet pipes 210 and oil return pipes 310 can be equal or unequal; and the number of oil outlet pipes 210 and oil return pipes 310 can be equal to the number of bearing seats, for example, each bearing seat is provided with one oil outlet pipe 210 and one oil return pipe 310. The number of oil outlet pipes 210 and oil return pipes 310 can be unequal to the number of bearing seats, for example, each bearing seat is provided with two oil outlet pipes 210 and one oil return pipe 310. All of these are within the protection scope of this application and are not limited here.
[0040] In the horizontal direction, the inlet 11 and the outlet 12 are respectively opened on both sides of the bearing housing. In this embodiment, in the x-axis direction, the inlet 11 is set close to the drying drum 30, and the outlet 12 is set away from the drying drum 30. Since the temperature of the bearing is higher the closer it is to the drying drum 30, the low-temperature lubricating oil enters the bearing housing from the inlet 11 and first contacts the position with the higher temperature. The flow path is longer, which ensures that there is enough time for heat exchange between the lubricating oil and the bearing, thus improving the cooling effect.
[0041] In this embodiment, the housing 100 is provided with an oil storage chamber 110 and an oil purification chamber 120. The oil purification chamber 120 is connected to the bearing housing inlet 11 via an oil outlet pipe 210, and the bearing housing outlet 12 is connected to the oil storage chamber 110 via a return oil pipe. A cooling and filtration system is connected between the oil storage chamber 110 and the oil purification chamber 120. The bearing housing inlet 11 and outlet 12 are arranged opposite each other in the horizontal direction. In this way, the lubricating oil in the oil purification chamber 120 enters the bearing housing from the oil outlet pipe 210, has sufficient time to contact the bearing for lubrication, and carries away the heat of the bearing. Then, it enters the oil storage chamber 110 through the return oil pipe 310, and after being filtered and cooled by the cooling and filtration system, it enters the oil purification chamber 120, forming a cycle, saving raw material costs and improving the cooling effect.
[0042] In some embodiments, such as Figure 1 and Figure 2 As shown, in the y-axis direction, the housing 100 is positioned below the height of the bearing housing outlet 12. The bearing housing inlet 11 is located above the bearing housing, and the outlet 12 is located below the bearing housing. In this way, the lubricating oil can flow to the outlet 12 under the action of gravity and flow back to the oil storage chamber 110 through the return oil pipe 310, eliminating the need for a pump and saving electrical energy.
[0043] In some embodiments, such as Figure 1 and Figure 2 As shown, the cooling and filtration system includes an oil pipeline 410, a first pump body 420, a filter device 430, and a cooling device. The oil pipeline 410 connects the oil storage chamber 110 and the clean oil chamber 120. From the oil storage chamber 110 to the clean oil chamber 120, the first pump body 420, the filter device 430, and the cooling device are sequentially arranged on the oil pipeline 410.
[0044] In this embodiment, the first pump body 420 draws oil from the oil storage chamber 110, filters it through the filter device 430, and then cools the lubricating oil to the target temperature before it flows into the clean oil chamber 120 for use. The target temperature can be set by those skilled in the art according to actual needs, such as 30°C or 40°C. This arrangement of the filtration and cooling system, compared to placing the filter device 430 and cooling device on the oil outlet pipe 210, allows some impurities to settle in the oil storage chamber 110. The filter device 430 then filters out the remaining impurities, ensuring that the oil in the clean oil chamber 120 is free of impurities and at a suitable temperature. This allows the oil to directly enter the bearing housing through the oil outlet pipe 210 for bearing lubrication and cooling. This reduces the possibility of the oil outlet system being blocked by impurities and the possibility of lubricating oil flowing into the bearing housing without sufficient cooling, ensuring the normal operation of the entire automatic lubrication equipment.
[0045] In one embodiment, reference continues Figure 1 and Figure 2 The cooling device is an air-cooled device 440, which is mounted on the housing 100. The heat dissipation fins 4410 of the air-cooled device 440 are located on the side of the air-cooled device 440 away from the housing 100 to facilitate heat dissipation. The air-cooled device 440 removes heat through airflow. The air-cooled device 440 is a common type of air cooler in the art, such as a partitioned air cooler, a jacketed air cooler, or a coiled air cooler, etc., which will not be described in detail here.
[0046] In one embodiment, such as Figure 2 As shown, the oil outlet pipeline system also includes a main pipeline 220, a second pump body 230, and a flow distribution device 240. The main pipeline 220 connects the clean oil chamber 120 and the flow distribution device 240. The second pump body 230 is mounted on the main pipeline 220 and located between the clean oil chamber 120 and the flow distribution device 240. The first end of the oil outlet pipeline 210 is connected to the flow distribution device 240, and the second end of the oil outlet pipeline 210 is connected to the inlet 11 of the bearing housing. In this embodiment, the oil outlet pipeline 210 includes a first oil outlet pipeline 2110 and a second oil outlet pipeline 2120. The flow distribution device 240 is connected to both the first end of the first oil outlet pipeline 2110 and the first end of the second oil outlet pipeline 2120. The second end of the first oil outlet pipeline 2110 is connected to the inlet 11 of the first bearing housing 10, and the second end of the second oil outlet pipeline 2120 is connected to the inlet 11 of the second bearing housing 20.
[0047] In this embodiment, by setting up a flow distribution device 240, the uniform distribution of oil in each oil outlet pipe 210 is ensured, thereby guaranteeing the cooling and lubrication effect on multiple bearings. The flow distribution device 240 can be, for example, a progressive distributor. Lubricating oil is delivered to the flow distribution device 240 under the action of the second pump body 230. The plungers inside the flow distribution device 240 actuate sequentially under the pressure of the lubricating oil to distribute the lubricating oil to each oil outlet pipe 210. Alternatively, the flow distribution device 240 can be a damping distributor, which proportionally delivers lubricating oil to each oil outlet pipe 210 according to the size of the metering and control components. Those skilled in the art can select the appropriate type of flow distribution device 240 based on actual conditions, all of which are within the scope of protection of this application.
[0048] In one embodiment, such as Figure 2 and Figure 3As shown, the automatic lubrication device also includes a controller (not shown in the figure), a first liquid level sensor (not shown in the figure) is installed in the clean oil chamber 120, and a second liquid level sensor 1110 is installed in the oil storage chamber 110. Both the first liquid level sensor and the second liquid level sensor 1110 are electrically connected to the controller. The controller is electrically connected to both the first pump body 420 and the second pump body 230. The controller is used to control the output flow of the first pump body 420 and the second pump body 230 according to the liquid level signals sent by the first liquid level sensor and the second liquid level sensor 1110.
[0049] Specifically, when the amount of lubricating oil in the clean oil chamber 120 detected by the first level sensor is much less than the amount of lubricating oil in the oil storage chamber 110 detected by the second level sensor 1110, the controller controls the first pump body 420 to increase the oil delivery speed by adjusting the motor speed of the first pump body 420 and the second pump body 230, while simultaneously controlling the second pump body 230 to decrease the oil delivery speed; when the amount of lubricating oil in the clean oil chamber 120 detected by the second level sensor 1110 is much less than the amount of lubricating oil in the oil storage chamber 110 detected by the first level sensor, the controller controls the first pump body 420 to decrease the oil delivery speed by adjusting the motor speed of the first pump body 420 and the second pump body 230, while simultaneously controlling the second pump body 230 to increase the oil delivery speed.
[0050] With this design, the amount of oil in the clean oil chamber 120 and the oil storage chamber 110 can be maintained within a balanced range, avoiding the situation where there is no lubricating oil in one of the chambers, and ensuring the normal operation of the automatic lubrication equipment.
[0051] In some embodiments, such as Figure 3 As shown, a level gauge 1210 is also installed on the outside of the housing 100. The level gauge 1210 is connected to the clean oil chamber 120, and the liquid level in the level gauge 1210 is flush with the liquid level in the clean oil chamber 120. The level gauge 1210 allows the operator to know the liquid level in the clean oil chamber 120 in real time, facilitating the operator's inspection. In another embodiment, a display screen electrically connected to the first level sensor can be installed on the outer wall of the housing 100 to facilitate the operator in knowing the liquid level in the clean oil chamber 120.
[0052] In some embodiments, such as Figures 1 to 3 As shown, a first temperature sensor is installed in the clean oil chamber 120, and a second temperature sensor 1120 is installed in the oil storage chamber 110. Both the first and second temperature sensors 1120 are electrically connected to the controller, which is electrically connected to the cooling device. The controller is used to adjust the cooling efficiency of the cooling device according to the temperature signals sent by the first and second temperature sensors 1120.
[0053] It should be noted that the sensors in the same cavity can be set separately or can be integrated into one structure. For example, a second liquid level sensor 1110 and a second temperature sensor 1120 can be set separately in the oil storage cavity 110, or they can be set as an integrated liquid level and temperature sensor. No limitation is made here.
[0054] By setting up a first temperature sensor, a second temperature sensor 1120, and a cooling device, the controller can adjust the cooling efficiency of the cooling device in real time according to the temperature signal. When the temperature of the clean oil chamber 120 detected by the first temperature sensor is too high, the controller can promptly improve the cooling effect of the cooling device until the temperature drops to the target temperature, ensuring the cooling effect while avoiding the waste of electrical energy.
[0055] In some embodiments, such as Figure 1 and Figure 2 As shown, a third temperature sensor is provided in both the first bearing housing 10 and the second bearing housing 20. The third temperature sensor is electrically connected to the controller, which is used to control the output flow of the second pump body 230 according to the temperature signal detected by the third temperature sensor.
[0056] By setting the controller to be electrically connected to the third temperature sensor and the second pump body 230, when the third temperature sensor detects that the temperature inside the bearing housing is too high, the controller sends a control signal to increase the motor speed of the second pump body 230. The flow rate of lubricating oil in the first bearing housing 10 and the second bearing housing 20 increases, which increases the efficiency of heat conduction and thus reduces the temperature inside the bearing housing.
[0057] In some embodiments, such as Figures 1 to 3 As shown, the automatic lubrication equipment also includes an alarm device, which is electrically connected to both the first and second level sensors 1110. The alarm device is used to issue an alarm when the reading of either the first or second level sensor 1110 is zero. The alarm device may include, for example, a warning light or a buzzer, or both. The alarm device flashes or sounds when the lubricating oil content in the empty oil chamber 120 or the oil storage chamber 110 is zero.
[0058] By setting up an alarm device, an alarm will be triggered in time when the lubricating oil content in the housing 100 becomes abnormal. Operators can promptly detect and repair the automatic lubrication equipment and troubleshoot any malfunctions, thus avoiding equipment damage or even safety accidents due to delayed detection.
[0059] In one embodiment, the housing 100 is provided with an oil replenishment port 140, which is located on one side of the oil storage chamber 110. A filter screen is provided on the oil replenishment port 140. In this way, the newly replenished lubricating oil is coarsely filtered on the filter screen before entering the oil storage chamber 110. It is then finely filtered again by the filter device 430 and cooled by the air-cooling device 440 before entering the clean oil chamber 120 for use. The oil replenishment port 140 located on one side of the oil storage chamber 110 avoids impurities in the newly replenished lubricating oil from clogging the oil outlet pipeline system, thus ensuring the normal operation of the automatic lubrication equipment.
[0060] The operation process of the above-mentioned automatic lubrication equipment is as follows:
[0061] Lubricating oil is added to the oil storage chamber 110 through the oil replenishment port 140. The cooling and filtration system is started. Under the action of the first pump body 420, the lubricating oil is filtered by the filter device 430 and cooled by the air-cooling device 440. After that, it enters the clean oil chamber 120 through the oil delivery pipe 410. Under the action of the second pump body 230, it is distributed by the flow distribution device 240 and enters the first oil outlet pipe 2110 and the second oil outlet pipe 2120. Then, it enters the bearing housing from the inlet 11 to lubricate the bearing and exchange heat. Under the action of gravity, it flows out from the outlet 12 and flows back to the oil storage chamber 110 through the first return oil pipe 3110 and the second return oil pipe 3120. After passing through the cooling and filtration system, it enters the clean oil chamber 120, realizing the recycling.
[0062] During the cycle, the controller receives signals from the first liquid level sensor, the second liquid level sensor 1110, the first temperature sensor, the second temperature sensor 1120, and the third temperature sensor, and controls the motor speed of the first pump body 420 and the second pump body 230 and the cooling efficiency of the cooling device in real time, thus realizing automatic control.
[0063] The automatic lubrication equipment provided in this application, by setting the inlet 11 and outlet 12 positions of the bearing housing, and the oil storage chamber 110 and clean oil chamber 120 connected through the cooling and filtration system, allows the lubricating oil to have sufficient time to contact the bearing for lubrication and to remove the heat from the bearing, forming a cycle, saving raw material costs, and also improving the filtration and cooling effects.
