Description

Technical Field

[0001] This utility model relates to the field of mechanical equipment technology, and in particular to a thin oil station with an improved cooling system. Background Technology

[0002] In recent years, with the sustained and rapid development of my country's economy, the machinery industry has made significant progress. Thin oil lubrication stations are now widely used in centralized lubrication systems for hydrostatic or sliding bearings in machinery and equipment in metallurgy, mining, cement, and power plants. They are primarily used for centralized lubrication of hydrostatic or sliding bearings and are typically installed in underground oil depots or pits near the machines requiring lubrication. A thin oil lubrication station usually consists of an oil tank, oil pump, cooling system, overflow valve, diversion valve assembly, return oil assembly, filter, and valves. During operation, the oil pump draws lubricating oil from the tank, and after passing through the filter and valves, it is directly delivered to the parts of the machinery requiring lubrication (such as gearboxes). This ensures good lubrication of the relatively moving parts of the machinery and removes metal particles worn during movement. The oil is then cooled by the filtration and cooling system before flowing back to the oil tank, forming a circulating lubrication system. Therefore, thin oil lubrication stations have high requirements for oil supply temperature and require a stable and reasonable supply temperature. Otherwise, if the oil supply to the thin oil station fails due to excessively high temperature, the oil supply will be interrupted, resulting in the bearings being damaged due to lack of lubrication. This will seriously affect the working efficiency of the mechanical equipment and the safe, stable and efficient operation of the production system.

[0003] Currently, most thin oil cooling stations use water-cooled systems. However, due to environmental differences, water quality varies significantly from place to place. In some environments, the water quality fails to meet the requirements of the cooling system. Poor-quality cooling water entering the system can severely damage the coolers, resulting in ineffective cooling and poor heat dissipation, thus affecting the safe and normal operation of the thin oil station. For example, in a coal mill workshop, the cooling water was not filtered or softened, containing a large amount of solid particles. Furthermore, the existing shell-and-tube coolers were old and lacked proper maintenance, leading to a significant accumulation of solid particles and scale on the inner walls of the tubes. This severely reduced the cooler's thermal conductivity, failing to meet cooling requirements. Actual measurements showed only a 1-2°C temperature difference between the cooling water inlet and outlet, resulting in virtually no heat exchange with the lubricating oil. The lubricating oil temperature after passing through the cooler reached over 60°C, far exceeding the normal operating temperature range (25°C-45°C) of the gearbox, making normal gearbox operation impossible.

[0004] Therefore, how to improve the cooling system to meet the cooling requirements of the thin oil station and ensure its continuous, stable, safe and normal operation, while avoiding damage to mechanical equipment (such as gearboxes) due to poor heat dissipation, has become a technical problem that technical personnel in the field urgently need to solve. Utility Model Content

[0005] This utility model provides a thin oil station with an improved cooling system that can operate continuously and stably, in order to solve the problem of poor heat dissipation caused by poor cooling effect of the thin oil station's cooling system, which leads to damage to mechanical equipment.

[0006] This utility model provides a thin oil station with an improved cooling system, comprising: a cooling system including a cooler, a water inlet cleaning device, and a water inlet filter; the water inlet cleaning device and the water inlet filter are sequentially arranged on the water inlet pipe of the cooler, and the water inlet filter is located on the side closer to the cooler; the cooler is a brazed cooler; the water inlet cleaning device is a spiral cleaner, and the water inlet filter is a Y-type filter; pressure monitoring devices and temperature monitoring devices are installed on both the oil side and water side pipes of the cooler.

[0015] This utility model provides a thin oil station with an improved cooling system. By utilizing the existing circulating cooling water pipes, the cooling system is improved. A brazed cooler is used to enhance the heat exchange efficiency of the cooling system, and a spiral separator and a Y-type filter are used to intercept at least 98% of solid particles in the cooling water, effectively improving the quality of the circulating cooling water.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions in the embodiments of this utility model are described clearly and completely below. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are also within the protection scope of this utility model.

[0021] like Figure 1 This utility model provides a thin oil station with an improved cooling system, comprising: a cooling system including a cooler 1, a water inlet cleaning device, and a water inlet filter. The water inlet cleaning device and the water inlet filter are sequentially arranged on the water inlet pipe of the cooler 1, and the water inlet filter is arranged on the side closer to the cooler 1; the cooler 1 is a brazed cooler; the water inlet cleaning device is a spiral cleaner 2, and the water inlet filter is a Y-type filter 3; pressure monitoring devices and temperature monitoring devices are installed on both the oil side and water side pipes of the cooler 1.

[0022] The cooling system of this thin oil station is an improvement on the existing cooling system. The commonly used shell-and-tube cooler 1 is replaced with a brazed cooler. Under the same exchange power, the volume of the brazed cooler is half that of the shell-and-tube heat exchanger, offering advantages such as smaller size, higher heat exchange efficiency, energy saving, and durability. This reduces the space occupied by cooler 1 in the thin oil station, making installation easier. Pressure monitoring devices are used to monitor water and oil pressure in the pipelines, while temperature monitoring devices are used to monitor water and oil temperatures in real time, allowing for timely adjustments to the cooling system's operating status and ensuring the cooling effect of the thin oil station, enabling the station to operate continuously and stably.

[0023] Since the cooling water commonly used in the prior art is unfiltered and unsoftened, it contains a large number of solid particles. In order to avoid the problem that the heat exchange efficiency of the cooler 1 will decrease due to the blockage of solid particles and thus fail to meet the working requirements, the cooling system of this utility model is also equipped with a device for removing dirt and filtering the water entering the cooler 1. The water inlet dirt removal device and the water inlet filter device can intercept at least 98% of the solid particles in the cooling water, effectively improving the quality of the circulating cooling water and ensuring that the heat dissipation efficiency of the cooler 1 is maintained at a high working level.

[0024] This utility model's thin oil station improves the cooling system by utilizing the existing circulating cooling water pipes to enhance the heat exchange efficiency of the cooling system, resulting in better cooling performance. It ensures that the lubricating oil temperature remains within the required operating temperature range of the equipment, achieving effective control of the thin oil station's oil supply temperature. This ensures that the lubrication system of the thin oil station and mechanical equipment can operate continuously and stably, thereby preventing damage to the mechanical equipment due to poor lubricating oil heat dissipation or excessively high oil temperature.

[0025] like Figure 2 or Figure 3 Preferably, at least two Y-type filters 3 are provided, and the two Y-type filters 3 are connected in series.

[0026] Preferably, the mesh size of the Y-type filter 3 near the cooler 1 is smaller than that of the Y-type filter 3 near the inlet water cleaning device.

[0027] To prevent clogging of the cooler 1, the improved cooling system utilizes a spiral separator 2 to remove larger solid particles from the circulating cooling water, and a Y-type filter 3 to remove smaller solid particles and suspended solids in the water. By using two Y-type filters 3 with different mesh sizes in series, the particle size of solid particles in the cooling water can be controlled within a small range, preventing clogging on the water side of the cooler 1 and ensuring the cleanliness of the cooling water. This allows the cooler 1 to maintain its cooling effect and heat exchange efficiency even with less cooling water, saving water costs. The specific mesh size of the Y-type filter 3 can be selected by those skilled in the art based on the needs of the work site and the quality of the cooling water; no specific limitation is made here.

[0028] like Figure 2 Preferably, the pressure monitoring device is a pressure gauge 4, and pressure gauges 4 are installed on the oil-side inlet and outlet pipes and the water-side inlet and outlet pipes of the cooler 1. Pressure gauges 4 are installed on the oil and water-side pipes of the cooler 1 to monitor the oil pressure and water pressure entering and exiting the cooler 1. By measuring the pressure difference between the oil side and / or the water side, it is possible to detect and determine in a timely manner whether the cooler 1 is blocked or otherwise.

[0029] like Figure 2 Preferably, a stainless steel ball valve 5 is installed between each pressure gauge 4 and the cooler 1. Stainless steel ball valves 5 are installed on the inlet and outlet pipes on the oil and water sides of the cooler 1, mainly to cut off the lubricating oil and water in the pipes during the maintenance of the cooler 1, so as to prevent the lubricating oil and water from spilling onto the ground or other parts of the equipment.

[0030] like Figure 2 Preferably, the temperature monitoring device is a thermometer 6, and thermometers 6 are installed on the oil-side inlet and outlet pipes and the water-side inlet and outlet pipes of the cooler 1.

[0031] like Figure 3Preferably, pressure gauges 4 are installed on both the front and rear pipes of the spiral separator 2; the bottom of the spiral separator 2 is connected to a drain pipe via a drain valve 21, and the other end of the drain pipe is connected to a sewage tank 22. The spiral separator 2 is mainly used to intercept solid particles with a density greater than water, thereby reducing the solid content in the water. When the pressure difference shown by the pressure gauges 4 before and after the spiral separator 2 reaches a set value (determined according to actual working conditions), the drain valve 21 at the bottom of the spiral separator 2 is opened, and the collected solid particles are discharged into the sewage tank 22 through the drain pipe. After the pollutants are discharged, the spiral separator 2 can resume efficient operation with a high interception rate, ensuring the cleanliness of the circulating cooling water and the cooling effect of the cooling system.

[0032] like Figure 2 Preferably, both the oil-side and water-side pipes of the cooler 1 are equipped with a sight glass 7 and a flow meter 8. By observing the sight glass 7, the material flow on the oil and water sides can be directly observed. The flow meter 8 can monitor the flow rate. By adjusting the opening of the stainless steel ball valve 5 on the pipe, the amount of oil and water in the pipe can be controlled, ensuring the normal operation of the cooling system and the stable supply of lubricating oil.

[0033] like Figure 3 Preferably, a check valve 9 is also installed on the outlet water pipe of the cooler 1; the pressure monitoring device and the temperature monitoring device are also electrically connected to a pressure alarm device and a temperature alarm device, respectively. The check valve 9 in the outlet water pipe protects the cooler 1 and the filter from damage caused by the return of circulating cooling water. The pressure alarm device and the temperature alarm device can trigger an alarm when the water pressure and temperature exceed predetermined values, promptly reminding operators and ensuring the safe operation of the cooling system and the thin oil station. It should be noted that the aforementioned pressure alarm device and temperature alarm device can be a buzzer alarm or other types of alarms; no specific limitation is made here.

[0034] The aforementioned thin oil station and cooling system are equipped with multiple brackets and fixing devices at appropriate locations. The specific locations can be selected by the staff themselves. These are used to fix and support the pipes and various devices to prevent damage to the pipes and equipment caused by human error or vibration of the pipes themselves.

[0035] It should be noted that arrows without annotations indicate the direction of material flow.

[0036] In a specific embodiment, the operation of the thin oil station with the improved cooling system is as follows: the lubricating oil in the thin oil station is heated by the gearbox, and when the hot lubricating oil returns to the oil tank, it first enters the oil side of the cooler 1 of the thin oil station for cooling, reducing the oil temperature to below 45°C, thereby ensuring that the internal components of the gearbox will not be damaged due to the excessively high temperature of the lubricating oil re-entering the gearbox.

[0037] The cooling water in cooler 1 comes from the circulating water network. It first passes through a spiral strainer 2 to intercept solid particles denser than water, removing larger solid impurities from the cooling water. Then, a two-stage Y-type filter 3 with decreasing mesh size is used in series to remove smaller solid impurities and suspended solids. Specifically, a Y-type filter 3 with 100-mesh and 160-mesh screens in series is used to reduce the solid content in the water to below 30 mg / L. The filtered cooling water enters the water side of cooler 1 to cool the lubricating oil. After heat exchange, the cooling water returns to the circulating water network through a check valve 9.

[0038] Stainless steel ball valves 5 and pressure gauges 4 are installed on the inlet and outlet pipes of both the oil and water sides of cooler 1. Pressure gauges 4 are also installed on the pipes before and after spiral separator 2 to facilitate monitoring of oil and water pressure in the pipes. The pressure difference can be used to promptly detect and determine whether there is any blockage in cooler 1, separator, or pipes. When the pressure difference shown by the pressure gauges 4 before and after spiral separator 2 reaches the set value, the drain valve 21 at the bottom of spiral separator 2 is opened, and the collected solid particles are discharged into the sewage tank 22 through the drain pipe. After the pollutants are discharged, spiral separator 2 can resume its efficient and high-interception operation.

[0039] Thermometer 6 is used for real-time monitoring of water and oil temperatures. The sight glass 7 allows for direct observation of material flow on both the oil and water sides. Flow meter 8 monitors the flow rate. Adjusting the opening of the stainless steel ball valve 5 on the pipeline controls the oil and water flow, ensuring the normal operation of the cooling system and a stable lubricating oil supply. The pressure and temperature alarm devices are buzzer alarms that activate when the water pressure and temperature exceed preset values, promptly alerting operators and ensuring the safe operation of the cooling system and thin oil station.

[0040] It should be noted that the detailed structure of some devices in this utility model is not described in detail, but belongs to the prior art known to those skilled in the art, and therefore will not be described again here. In addition, the parts of this device not described are the same as or can be implemented using existing technology.

[0041] It should be noted that those skilled in the art, under the guidance of this utility model, can also make some modifications to the design of the above system. For example, the equipment in the system is also equipped with level gauges, overflow / nitrogen pipelines, etc.; pumps, pressure sensors, flow meters or temperature sensors are installed on the conveying pipelines inside the system in different units or devices, and different valves, such as pressure relief valves, pressure regulating valves, safety valves, pneumatic valves, etc., are also installed to regulate and stabilize the pressure of the entire system, and the opening degree of the valves can also be adjusted to regulate the flow rate of materials in the pipeline, etc.

[0042] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it; although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
