Abstract
Description
Technical Field
[0001] This application belongs to the technical field of sand mills, and particularly relates to an oil lubrication system for sand mill bearings. Background Technology
[0002] The lubrication system for bearing oil supply generally uses gravity-fed oil return pipelines, which require a large diameter.
[0003] A Chinese patent with publication number CN112983761 B discloses a sliding bearing lubrication system and a sliding bearing. The sliding bearing lubrication system includes an oil supply pipe and a bearing housing. An oil inlet channel is formed inside the bearing housing and is connected to the oil supply pipe. At least one bearing is installed on the bearing housing. The bearing includes a bearing bush and an oil groove is formed on the bearing bush. The oil groove is connected to the oil inlet channel. The lubricating medium flows into the oil groove of the bearing along the oil supply pipe and through the oil inlet channel.
[0004] The oil inlet channel in the aforementioned invention is located inside the bearing housing, eliminating the need for additional oil inlet channels and components outside the bearing housing. Furthermore, the oil inlet channel is less affected by vibration, ensuring the reliability of lubrication and the stability of the bearing lubrication system. However, this invention cannot adjust the oil flow rate, and the oil supply is not intuitive, resulting in poor performance. Utility Model Content
[0005] The purpose of this application is to address the aforementioned technical problems by providing an oil lubrication system for sand mill bearings. This system facilitates adjustment of the oil flow rate, provides a more intuitive oil supply method, has a simple structure, good visibility, and is easy to operate.
[0006] This application provides an oil lubrication system for a sand mill bearing, comprising a system body, the system body including:
[0007] Thin oil lubrication pump station, including inlet hydraulic pipe;
[0008] The flow divider is connected to the inlet hydraulic pipe;
[0009] A float flow meter, connected to the outlet of the flow divider block;
[0010] The first bearing housing has its oil inlet connected to the float flow meter;
[0011] The second bearing housing has its oil inlet connected to the float flow meter;
[0012] Intermediate oil return tank, including the main oil return pipeline;
[0013] The float flowmeter is equipped with a regulating valve, the first bearing housing is equipped with a first return oil pipe, the second bearing housing is equipped with a second return oil pipe, the first bearing housing is connected to the intermediate return oil tank through the first return oil pipe, the second bearing housing is connected to the intermediate return oil tank through the second return oil pipe, and the intermediate return oil tank is connected to the thin oil lubrication pump station through the main return oil pipeline.
[0014] In this technical solution, an inlet hydraulic pipe is installed in the thin oil lubrication pump station, which is connected to a distribution block. The distribution block has two outlets, one leading to a float flow meter, and the other to a first bearing housing and the other to a second bearing housing. The first return oil pipe in the first bearing housing and the second return oil pipe in the second bearing housing are both connected to an intermediate return oil tank. The intermediate return oil tank is then connected to the thin oil lubrication pump station via a main return oil pipeline, thus forming a complete oil lubrication system. When the system is lubricating, the thin oil lubrication pump station is started, and lubricating oil enters the distribution block along the inlet hydraulic pipe. Inside, the oil is split into two streams along the diverter block, each flowing into one of the two float flowmeters. Each float flowmeter is equipped with a regulating valve, allowing operators to easily adjust the oil flow rate. The lubricating oil enters the first and second bearing housings respectively. After lubrication is completed, the oil in the first and second bearing housings flows through the first and second return oil pipes to the intermediate return oil tank. The oil in the intermediate return oil tank then flows back to the thin oil lubrication pump station through the main return oil pipeline. This solves the flow control problem in the bearing oil lubrication system of the 3900L sand mill, enabling visible oil supply with a graduated flow rate. The system is simple in structure, highly visible, and easy to operate.
[0015] Furthermore, the oil inlets of both the first and second bearing housings are located at the top, the first oil return pipe is located at the bottom of the first bearing housing, and the second oil return pipe is located at the bottom of the second bearing housing.
[0016] In this technical solution, by placing the oil inlets of the first and second bearing housings at the top, and the first and second oil return pipes at the bottom of the first and second bearing housings, lubricating oil enters from the oil inlets at the top of the first and second bearing housings during lubrication. With the assistance of gravity, the lubricating oil can fully lubricate the bearings at the first and second bearing housings. After the lubrication work is completed, the lubricating oil flows out along the first and second oil return pipes at the bottom, facilitating the return of the lubricating oil to the thin oil lubrication pump station and reducing energy consumption.
[0017] Furthermore, the system body is also equipped with auxiliary supports and protective plates;
[0018] The float flowmeter is vertically mounted on the protective plate, and the protective plate is threadedly connected to the auxiliary support. The diverter block is mounted on the auxiliary support.
[0019] In this technical solution, by setting an auxiliary support and a protective plate in the system body, and the float flow meter is vertically installed on the protective plate, the protective plate and the auxiliary support are threaded together, and the flow divider is installed on the auxiliary support, the auxiliary support and the protective plate can reduce the vibration effect and reduce the impact of vibration on the float flow meter, so that the fluid can flow through the float flow meter from bottom to top, ensuring that the float flow meter can stably perform measurement and adjustment work.
[0020] Furthermore, the diverter block is installed directly below the center of the float flowmeter.
[0021] In this technical solution, by installing the flow divider block directly below the center of the float flow meter, the lubricating oil can enter the float flow meters on both sides evenly along the flow divider block, making the oil flow more uniform and the lubricating oil can enter the float flow meter stably, further improving the adjustment capability of the float flow meter.
[0022] Furthermore, the auxiliary bracket is provided with mounting holes;
[0023] The mounting holes are evenly distributed on the auxiliary bracket.
[0024] In this technical solution, mounting holes are set at the auxiliary support. The mounting holes are evenly distributed on the auxiliary support, which facilitates the installation of various components and oil pipes. The oil pipes can be reasonably arranged according to the position of the mounting holes, which facilitates the maintenance of the system body by the staff.
[0025] Furthermore, both the first bearing housing and the second bearing housing are equipped with lifting rings.
[0026] In this technical solution, lifting rings are provided at the first bearing housing and the second bearing housing. The lifting rings facilitate the lifting equipment to attach to the lifting rings and move the bearing housing. This makes it easier for workers to move the first bearing housing and the second bearing housing to a suitable working position, and facilitates the lubrication of the system body.
[0027] The beneficial effects of this application are:
[0028] 1. The float flow meter is equipped with a regulating valve, which makes it convenient for operators to adjust the oil flow rate. This solves the flow control problem in the bearing oil lubrication system of the 3900L sand mill, making the oil supply visible, with a scale value for the flow rate. It has a simple structure, good visibility, and is easy to operate.
[0029] 2. When the system body is lubricating, the control oil lubrication pump station is started. The lubricating oil enters the diverter block along the oil inlet hydraulic pipe, and then splits into two paths along the diverter block, entering the two float flow meters respectively. The lubricating oil enters the first bearing housing and the second bearing housing respectively. After the lubrication work is completed, the oil in the first bearing housing and the second bearing housing flows to the return oil intermediate tank through the first return oil pipe and the second return oil pipe. The oil in the return oil intermediate tank flows back to the oil lubrication pump station through the main return oil pipe, completing the lubricating oil circuit.
[0030] 3. During lubrication, the lubricating oil enters from the oil inlet at the top of the first and second bearing housings. With the assistance of gravity, the lubricating oil can fully lubricate the bearings in the first and second bearing housings. After the lubrication is completed, the lubricating oil flows out along the first and second return oil pipes at the bottom, which facilitates the return of the lubricating oil to the thin oil lubrication pump station and reduces energy consumption.

[0037] The embodiments of this application are described in detail below with reference to the accompanying drawings, through specific examples and application scenarios.
[0038] Example 1:
[0039] like Figure 1-3 As shown, this application embodiment provides an oil lubrication system for a sand mill bearing, including a system body 100, the system body 100 comprising:
[0040] Thin oil lubrication pump station 200, including oil inlet hydraulic pipe 210;
[0041] The flow divider block 300 is connected to the inlet hydraulic pipe 210;
[0042] A float flowmeter 400 is connected to the outlet of the diverter block 300;
[0043] The first bearing housing 500 has its oil inlet connected to the float flow meter 400;
[0044] The second bearing housing 600 has its oil inlet connected to the float flow meter 400;
[0045] The intermediate oil return tank is 700, including the main oil return pipeline 710;
[0046] The float flowmeter 400 is equipped with a regulating valve 410, the first bearing housing 500 is equipped with a first return oil pipe 510, the second bearing housing 600 is equipped with a second return oil pipe 610, the first bearing housing 500 is connected to the intermediate return oil tank 700 through the first return oil pipe 510, the second bearing housing 600 is connected to the intermediate return oil tank 700 through the second return oil pipe 610, and the intermediate return oil tank 700 is connected to the thin oil lubrication pump station 200 through the main return oil pipeline 710.
[0047] By installing an inlet hydraulic pipe 210 in the thin oil lubrication pump station 200, which is connected to a flow divider block 300, and having two outlets on the flow divider block 300 leading to two float flow meters 400 respectively, which in turn lead to a first bearing housing 500 and a second bearing housing 600 respectively, a complete oil lubrication system is formed. When the system body 100 is performing lubrication work, the thin oil lubrication pump station 200 is started, and lubricating oil enters along the inlet hydraulic pipe 210. Within the diversion block 300, the oil is split into two paths, each entering one of the two float flowmeters 400. Each float flowmeter 400 is equipped with a regulating valve 410, allowing operators to easily adjust the oil flow rate. The lubricating oil enters the first bearing housing 500 and the second bearing housing 600 respectively. After lubrication, the oil in the first bearing housing 500 and the second bearing housing 600 flows through the first return oil pipe 510 and the second return oil pipe 610 to the intermediate return oil tank 700. The oil in the intermediate return oil tank 700 then flows back to the thin oil lubrication pump station 200 through the main return oil pipe 710.

With the assistance of gravity, the lubricating oil can fully lubricate the bearings at the first bearing housing 500 and the second bearing housing 600. After the lubrication work is completed, the lubricating oil flows out along the first oil return pipe 510 and the second oil return pipe 610 at the bottom, which facilitates the return of the lubricating oil to the thin oil lubrication pump station 200, reducing energy consumption.
[0050] Furthermore, the system body 100 is also provided with an auxiliary support 110 and a protective plate 120;

[0056] Furthermore, the auxiliary bracket 110 is provided with mounting holes 111;
[0057] The mounting holes 111 are evenly distributed on the auxiliary bracket 110.
[0058] By setting mounting holes 111 at the auxiliary support 110, the mounting holes 111 are evenly distributed on the auxiliary support 110.
