Description

Technical Field

[0001] This utility model relates to the field of aluminum foil production technology, and in particular to a bearing housing cooling device. Background Technology

[0002] Aluminum foil production, especially high-speed double-rolling, is a high-tech and high-risk process. The rollers on the production line are the core components; they rotate at extremely high speeds, applying enormous pressure to the aluminum strip to thin it.

[0003] The bearing housing of the rotating roller is a key structure that supports these rollers. It is filled with lubricating oil (or grease) to keep the bearings cool and lubricated. During the production process, the high-speed rotation of the main shaft generates high temperatures, which causes the temperature of the bearing housing to rise. When the bearing housing is damaged and leaks oil, the temperature of the bearing housing will rise to the flash point of the lubricating oil, which can cause the bearing housing to catch fire, posing a safety hazard to the factory and affecting the normal production of aluminum foil.

[0004] Therefore, it is necessary to continuously monitor the temperature of the bearing housing. There are two existing monitoring methods. The first is manual inspection, where workers discover problems such as oil leaks, abnormal noises, and high temperatures by "seeing, hearing, touching, and smelling". This method is highly subjective, cannot monitor in real time, and has a delayed response to sudden failures. The second method is to place a temperature measuring element on the outside of the bearing housing, facing it directly. The temperature measuring point is usually on the outer shell of the bearing housing, and the measured temperature is the outer shell temperature, which is lower than the core temperature inside the bearing. There is also a delay in heat conduction, so when an alarm is triggered, the fault may already be quite serious. Utility Model Content

[0005] In view of the technical problems existing in the background art, the utility model provides a bearing housing cooling device, which can reduce the temperature of the bearing housing and provide timely feedback and extinguishing of fire in the bearing housing.

[0006] To achieve the above objectives, the technical solution provided by this utility model is as follows:

[0007] A bearing housing cooling device includes a main support, which is disposed on the outside of the bearing housing and in contact with multiple surfaces of the bearing housing. The main support includes a liquid cooling module, which is hollow and has an annular opening. The middle part of the bearing housing extends into the opening. A partition is disposed inside the liquid cooling module, which forms a chamber around the middle part of the bearing housing. The coolant flows in the chamber to reduce the temperature of the bearing housing.

[0008] Preferably, the liquid cooling module has an inlet on one side and an outlet on the opposite side of the inlet. Pipes are connected to the inlet and outlet respectively, and the coolant enters from the inlet.

[0009] Preferably, the main support also includes several air-cooled modules, which are respectively arranged on both sides of the liquid-cooled module.

[0010] Preferably, the air-cooling module is L-shaped, with a socket on the air-cooling module and a connection port on the bearing housing. The air-cooling module is supported on the shoulder of the bearing housing, and the socket and the connection port are aligned.

[0011] Preferably, the air-cooled module is hollow inside, and an air intake pipe and an exhaust fan are provided on the air-cooled module.

[0012] Preferably, the main support also includes a monitoring component, which includes a support cylinder and a monitoring element. The support cylinder is detachably inserted into the opening, and the monitoring element is disposed inside the support cylinder.

[0013] Preferably, a fire extinguishing pipe is provided on the support cylinder, the fire extinguishing pipe extends into the inside of the support cylinder, and one end of the fire extinguishing pipe is directly opposite the main shaft.

[0014] Preferably, the support cylinder is provided with several pressure relief holes.

[0015] This utility model has the following advantages and beneficial effects:

[0016] In this utility model:

[0017] 1. Synergistic cooling and efficient temperature control: The liquid cooling module allows the coolant to contact multiple surfaces of the bearing housing through a surrounding chamber. Combined with the forced convection of the air cooling modules on both sides, it forms a dual heat dissipation of "liquid cooling + air cooling", which significantly reduces the temperature of the bearing housing and avoids the risk of lubricating oil failure or fire caused by high temperature.

[0018] II. Real-time monitoring and accurate early warning: The monitoring components are located inside the support cylinder, close to the core area of ​​the bearing housing. They can collect real-time temperature data, solving the problem of lag in traditional shell temperature measurement, and providing early warning of high-temperature faults, thus buying time for emergency response.

[0019] III. Emergency Firefighting and Safety Assurance: The fire extinguishing pipeline is positioned directly opposite the main shaft and, in conjunction with the pressure relief function of the pressure relief hole, can quickly spray extinguishing agent and spread it to cover the fire source in the event of a fire, extinguishing the initial fire in a timely manner and reducing equipment damage and production interruption losses.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0028] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0029] Example

[0030] like Figures 1-5 As shown, a bearing housing cooling device is mainly used for cooling, temperature monitoring, and fire emergency handling of bearing housing 5 in a high-speed aluminum foil rolling production line. Through multiple heat dissipation and safety protection designs, the device improves the safety of equipment operation.

[0031] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6As shown, a bearing housing cooling device includes a main support 1, which is a combined structure adapted to the contour of the bearing housing 5. The material is a high-temperature resistant metal (such as stainless steel). It includes a liquid cooling module 2, an air cooling module 3, and a monitoring component 4. The liquid cooling module 2 is a hollow structure with an annular opening 21 in the middle. The inner diameter of the opening 21 matches the shaft diameter of the middle part of the bearing housing 5. The middle part of the bearing housing 5 (the part near the main shaft) extends into the opening 21. The inner wall of the liquid cooling module 2 is fitted to the outer cylindrical surface of the bearing housing 5. A partition 22 is welded inside the liquid cooling module 2, which divides the internal space into two chambers 23 surrounding the middle of the bearing housing 5. A liquid inlet 24 is provided on the lower part of one side of the liquid cooling module 2, and an outlet 25 is provided on the opposite side of the liquid inlet 24. The liquid inlet 24 and the outlet 25 are respectively connected to an external coolant circulation system (such as a water chiller) through pipes 26. The water chiller is connected to the liquid inlet 24 through a high-pressure pipe. The coolant (such as industrial water or antifreeze) enters the chamber 23 from the liquid inlet 24, flows along the annular path and absorbs the heat of the bearing housing 5, and is discharged from the liquid outlet 25, forming a continuous cooling circulation system.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 As shown, there are two air-cooled modules 3, which are symmetrically distributed on both sides of the liquid-cooled module 2. The air-cooled module 3 has an L-shaped structure. The horizontal section of the air-cooled module 3 is supported on the shoulder of the bearing housing 5 and fits tightly against the plane of the shoulder. The vertical section fits against the side of the bearing housing 5 to increase the heat dissipation contact area. The end of the horizontal section of the air-cooled module 3 is provided with a socket 31, and the bearing housing 5 is provided with a connection port 51. The connection port 51 is used to insert bolts to connect the upper and lower bearing housings into a whole. The socket 31 is aligned with the connection port 51 pre-set on the shoulder of the bearing housing 5. After aligning the socket 31 and the connection port 51, the bolt is inserted, which can make the air-cooled module 3 and the bearing housing 5 stably connected. The air-cooled module 3 is hollow inside to form an air duct. One end of the air-cooled module 3 is provided with an air inlet pipe 32 (connected to the workshop compressed air or cooling fan). One end of the air-cooled module 3 is also provided with an exhaust fan 33. Cold air enters the air duct from the air inlet pipe 32 and is discharged by the exhaust fan 33, so that the interior of the air-cooled module 3 is in a low temperature state. The air-cooled module 3 is in contact with the surface of the bearing housing 5, and carries away the surface heat of the bearing housing 5.

[0033] like Figure 1 , Figure 4As shown, the monitoring component 4 includes a support cylinder 41 and a monitoring element 42. The support cylinder 41 is a cylindrical metal cylinder with a threaded section at one end and a threaded section at the opening 21. The support cylinder 41 is screwed into the opening 21 to fix the support cylinder 41 and the liquid cooling module 2. The monitoring element 42 is an infrared temperature sensor or thermocouple. The monitoring element 42 is fixed inside the support cylinder 41, with the detection end facing the connection between the bearing seat 5 and the spindle (core heating area). It collects temperature data in real time and transmits it to the control system.

[0034] like Figure 1 , Figure 4 , Figure 6 As shown, a fire extinguishing pipe 43 is installed on the support cylinder 41. The fire extinguishing pipe 43 is a metal pipe, one end of which passes through the support cylinder 41 and extends into the interior of the support cylinder 41, with the port facing the connection position between the main shaft and the bearing seat 5 (a high-risk fire area). The other end is connected to an external fire extinguishing system (such as a dry powder storage tank or an inert gas cylinder). When the monitoring device 42 detects that the temperature of the bearing seat 5 reaches the ignition temperature, the external fire extinguishing system will work to promptly extinguish the fire on the bearing seat 5 (the switch and control system of the dry powder storage tank are connected, and the switch of the dry powder storage tank is triggered when the control system detects that the temperature is high), so as to prevent the fire from further affecting other structures in the factory and thus causing safety hazards.

[0035] like Figure 1 , Figure 4 As shown, a number of pressure relief holes 44 are provided through the support cylinder 41. The pressure relief holes 44 penetrate the side wall of the support cylinder 41 and are evenly distributed along the circumference of the support cylinder to prevent the support cylinder 41 from forming a closed space. When the temperature of the bearing seat 5 rises, the internal air pressure of the support cylinder 41 will rise. The pressure relief holes 44 can be used to release high-pressure gas. At the same time, the dry powder or gas discharged by the external fire extinguishing system can be discharged from the pressure relief holes 44.

[0036] The monitoring component 42 collects the temperature of the core area of ​​the bearing housing 5 in real time and transmits the data to the control system. When the temperature exceeds the preset threshold (such as 70°C), the system issues an early warning and increases the coolant flow and air cooling intensity. If a fire occurs (the temperature rises sharply above the flash point), the control system automatically activates the fire extinguishing system. The extinguishing agent is sprayed to the fire source through the fire extinguishing pipe 43, and at the same time, the pressure relief hole 44 releases high-pressure gas to ensure that the extinguishing agent is fully diffused and covered. The monitoring component 4 is connected in a detachable manner, which is convenient for installation. After the fire is extinguished, it is easy to remove the monitoring component 4 for cleaning in a timely manner. It is also convenient to regularly remove and check the stability of the monitoring component 42.

[0037] Working principle: Align the opening 21 of the liquid cooling module 2 with the middle of the bearing housing 5, so that the inner wall fits against the outer surface of the bearing housing 5. At this time, align the insertion port 31 of the air cooling module 3 with the connection port 51 on the shoulder of the bearing housing 5. Screw bolts into the insertion port 31 and the connection port 51 to fix them, so that the entire main support 1 and the bearing housing 5 are fixedly connected. The support cylinder 41 is fixed to the opening position of the liquid cooling module 2 by threads, so that the monitoring component 42 is aligned with the core heat generation area. Connect the pipe 26 between the liquid inlet 24 and the liquid outlet 25 to the coolant circulation system to ensure smooth flow of coolant. Then connect the air inlet pipe 32 to the compressed air source. Finally, connect... Fire extinguishing pipe 43 leads to the external fire extinguishing system, activating the coolant circulation system. Coolant enters chamber 23 from inlet 24, absorbs heat from bearing housing 5, and is discharged from outlet 25, continuously reducing the temperature in the middle of bearing housing 5. Cold air enters the air duct through inlet pipe 32 and exchanges heat with the side of bearing housing 5. Hot air is discharged by exhaust fan 33. Air cooling and liquid cooling work together to enhance heat dissipation. Monitoring device 42 collects the temperature of the core area of ​​bearing housing 5 in real time. If a fire occurs (temperature rises sharply above the flash point), the control system automatically activates the fire extinguishing system. Fire extinguishing agent is sprayed to the fire source through fire extinguishing pipe 43 to extinguish the fire.

[0038] This utility model effectively solves the problems of high temperature risk and monitoring lag in bearing housing 5 through the integrated design of liquid cooling and air cooling, real-time temperature monitoring and emergency fire extinguishing, significantly improving the safety and continuity of aluminum foil production, and is suitable for cooling protection of bearing housing 5 in various high-speed rotating equipment.

For those skilled in the art, the present utility model can have various modifications and variations. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
