[0002] Currently, for the beater equipment used in fruit and vegetable juicing, a rotor rotates in a screen, and impurities and juice are separated by centrifugal force. This structure adopts a cantilever shaft structure, and the bearing load is very large, especially prone to high temperature, resulting in frequent damage to the bearing and affecting production. In particular, in order to improve production efficiency, it is necessary to increase the current equipment of about 22 kw to be driven by a motor of more than 100 kw. The problem of bearing heating frequently occurs, seriously restricting the improvement of production efficiency. Without solving the problem of too high bearing temperature, it is impossible to achieve the technical improvement of high-power beaters. Summary of the Invention

[0005] The spiral tube heat exchanger is installed in the inner cavity of the bearing chamber.

[0006] A method for controlling the temperature of a beater bearing chamber includes the following steps: the temperature sensor detects the oil temperature of the lubricating oil, and after reaching the set temperature, the inlet water temperature control valve is opened, and the pipe with cooling water exchanges heat with the lubricating oil to keep the working temperature of the lubricating oil within the specified range and ensure the best working temperature of the lubricating oil.

[0007] The advantages of the present invention are as follows: adopting the design concept of mechatronics to realize the controllable temperature of the lubricating oil; creatively installing a spiral tube heat exchanger in the space of the bearing chamber; using cooling water for cooling, which is safe and reliable.

The spiral tube heat exchanger 3 is installed in the cavity of the bearing chamber 2. One end of the spiral tube heat exchanger 3 is connected to the cooling water pipeline 9, and the other end of the spiral tube heat exchanger 3 is connected to the drainage pipeline 8. The water inlet pipe is equipped with a temperature control valve 4, which can adjust the flow rate.

[0012] Embodiment 2: As Figure 1 shown, a temperature control device for the bearing chamber of a beater, one end of the spiral tube heat exchanger 3 is connected to the drainage pipeline 8, the other end of the spiral tube heat exchanger 3 is connected to one end of the temperature control valve 4, the other end of the temperature control valve 4 is connected to the cooling water pipeline 9, the motor 7 is connected to the rotating mechanism of the bearing chamber 2, and the other end of the rotating mechanism is connected to the beater rotor and the cavity 1. The temperature sensor 5 is installed in the bearing chamber 2, and the programmable temperature controller 6 is respectively connected to the temperature control valve 4 and the temperature sensor 5.

[0013] Embodiment 3: As Figure 1 shown, a temperature control method for the bearing chamber of a beater includes the following steps: The temperature sensor 5 detects the oil temperature of the lubricating oil. After reaching the set temperature, the inlet water temperature control valve 4 is opened, and the cooling water exchanges heat with the lubricating oil to make the working temperature of the lubricating oil within the specified range. The lubricating oil ensures the best working temperature, ensures the normal working state of the bearing, enables the large-load and high-power beater to work normally, and achieves the purpose of increasing production capacity.

[0014] It includes the following steps:

[0016] Step 2: The lubricating oil level exceeds the level of the level sensor.

[0017] Step 3: Use the temperature controller connected to the temperature sensor to display the temperature on the temperature controller.

[0018] Step 4: Set the oil temperature alarm limit on the temperature controller.

[0019] Step 5: During the operation of the equipment, the oil temperature gradually rises due to the friction of the bearings.

[0020] Step 6: When the oil temperature reaches the set alarm temperature, the controller opens the water inlet valve.

[0021] Step 7: Cooling water passes through the coil cooler placed in the bearing box to cool the lubricating oil to ensure that the temperature is within the reasonable range of 60-80°C.

[0022] Step 8: The lubricating oil takes away the heat of the bearing by lubricating the bearing, ensuring that the bearing runs at a normal temperature of 60-80℃.

[0023] The temperature sensor detects the lubricating oil temperature. When it reaches the set temperature of 60℃, the water inlet temperature control valve is opened, and the cooling water pipe exchanges heat with the lubricating oil to achieve the working temperature of the lubricating oil within the specified range of 60-80℃. The lubricating oil ensures the optimal working temperature of 60℃, 65℃, 70℃, 75℃ or 80℃.
