Description

Technical Field

[0001] This utility model relates to the field of roller conveyor technology for heating furnaces in metallurgical equipment, and specifically to a roller conveyor cooling water modification device for improving bearing service life. Background Technology

[0002] In industrial production, especially in metal processing industries such as steel and aluminum, roller conveyor systems are one of the key pieces of equipment on the production line. These roller conveyors not only need to withstand high temperatures and heavy loads, but also need to maintain stable rotational performance to ensure that materials can pass smoothly through each process stage. However, in actual operation, due to prolonged exposure to high-temperature environments, especially for roller conveyors that are close to heating sources or in direct contact with hot materials, their bearings are prone to premature failure due to overheating.

[0003] The existing roller bearings of the heating furnace are exposed to high temperatures for extended periods. Their cooling system uses DN32 diameter inlet and outlet water pipes, resulting in insufficient return water flow and low cooling efficiency. Actual bearing temperatures exceed 80℃, easily leading to bearing seizure, frequent replacements, and increased maintenance costs. Traditional technologies only adjust the inlet pipe diameter or add external cooling equipment, but do not address the insufficient return water flow systematically, thus failing to effectively solve the bearing wear problem caused by high temperatures.

[0004] Therefore, there is an urgent need to design a roller cooling water modification device to improve the service life of bearings, in order to solve the problems of low cooling efficiency, frequent replacement, and inability to effectively solve bearing wear caused by high temperature in the existing technology. Utility Model Content

[0005] In view of the problems existing in the prior art, the purpose of this utility model is to provide a roller cooling water modification device to improve the service life of bearings.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a roller cooling water modification device to improve the service life of bearings, including a cooling water pipe, a thermometer and a water flow control valve. The cooling water pipe is located around the roller, and a spiral guide vane is provided inside the cooling water pipe to divide the roller into three sections. The thermometer is located on one side of the roller, and the water flow control valve is located at the inlet of the cooling water pipe.

[0007] Specifically, the cooling water pipe includes an inlet pipe and a return pipe, and the cooling water pipe adopts a large-diameter water pipe, which includes an inner layer and an outer layer.

[0008] Specifically, the inner layer of the cooling water pipe is made of copper alloy, and the outer layer of the cooling water pipe is made of ceramic coating.

[0009] Specifically, the spiral guide vane is located inside the cooling water pipe and is rotatable.

[0010] Specifically, the thermometer is located on one side of each section of the roller conveyor, and the thermometer is equipped with a screen.

[0011] Specifically, there are three water flow control valves, which are respectively located at the inlet of the cooling water pipe of the three sections of the roller conveyor.

[0012] This utility model has the following beneficial effects:

[0013] This utility model designs a roller conveyor cooling water modification device to improve bearing life. The spiral guide design increases heat dissipation efficiency by 20%, reduces return water temperature by an additional 5-8℃, and extends bearing life by another 15%. The zoned cooling design reduces water waste and lowers overall energy consumption by 10%-15%. The composite pipe material reduces environmental heat pollution and lowers workshop temperature by 3-5℃. The return water flow rate is increased by more than 50%, and the bearing temperature drops from 80℃ to below 50℃, preventing seizure. The bearing life is extended by more than 2 times, and annual maintenance costs are reduced by 30%-40%. Attached Figure Description

[0017] The technical solutions of the present utility model will be described in further detail below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0018] like Figures 1-2 As shown, a roller conveyor 4 cooling water modification device for improving bearing service life includes a cooling water pipe 1, a thermometer 2 and a water flow control valve 3. The cooling water pipe 1 is located around the roller conveyor 4 and has a spiral guide vane 1.3 inside to divide the roller conveyor 4 into three sections. The thermometer 2 is located on one side of the roller conveyor 4 and the water flow control valve 3 is located at the inlet of the cooling water pipe 1.

[0019] Cooling water pipes 1 are installed around roller conveyor 4. Roller conveyor 4 is connected to cooling water pipes 1 through water pipes. Cooling water pipes 1 include inlet pipes and return pipes. Cooling water pipes 1 are large-diameter DN65 thick water pipes. Cooling water pipes 1 are used to cool down roller conveyor 4. Cooling water pipes 1 are divided into an outer layer 1.1 and an inner layer 1.2. The outer layer is made of ceramic coating material and is used for heat insulation to prevent heat from dissipating into the workshop. The inner layer is made of copper alloy material. Copper alloy material conducts heat quickly and is used for rapid heat absorption. All the heat is transferred to the water flow, reducing the workshop temperature by 3-5℃, making the workers more comfortable. There are also spiral guide vanes 1.3 inside cooling water pipes 1. These spiral metal vanes rotate when the water flows through, transferring heat to the water pipe wall, which further reduces the temperature of the roller conveyor 4 bearings by 5-8℃, extending the bearing life by 15%.

[0020] The roller conveyor 4 is divided into three sections from the steel outlet: front, middle, and rear. Each section of the roller conveyor 4 is equipped with a thermometer 2 and a display screen. The thermometer 2 is used to measure the temperature of each section of the roller conveyor 4, and the display screen is used to allow workers to read the temperature conveniently and quickly.

[0021] Water flow control valve 3 is installed on the inlet of the cooling water pipe 1 of the three sections of roller conveyor 4. The water flow control valve 3 is used by the worker to adjust the water flow according to the temperature of thermometer 2 so that the roller conveyor 4 is kept at the optimal working temperature.
