Description

Technical Field

[0001] The invention belongs to the technical field of slicer bearing box cooling, and in particular relates to a device and a method for automatically adjusting the temperature of a slicer bearing box. Background Art

[0002] During the operation of the slicer, the bearing box is the core component, and the temperature of the bearing box will directly affect the service life of the bearing box. The bearing box generates heat during operation. If the heat cannot be dissipated in time, the service life of the bearing box will be seriously shortened.

[0003] In the traditional bearing box heat dissipation method, the antifreeze flowing into each bearing box cannot be changed, which will cause the real-time temperature of the bearing box to be inconsistent during operation, resulting in different operating environment conditions for each bearing box. Therefore, the loss of each bearing box is different, which in turn makes bearing maintenance unpredictable. Summary of the invention

[0004] In view of various deficiencies in the prior art, the inventor has studied and designed a device and method for automatically adjusting the temperature of a slicer bearing box through long-term practice.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A device for automatically adjusting the temperature of a slicer bearing box includes an antifreeze tank, a heat exchange component and an antifreeze detection component connected to the antifreeze tank through a pipeline, and a motor valve component connected to the heat exchange component through a pipeline. A cooling water outlet component and a cooling water inlet component are provided on one side of the heat exchange component.

[0007] Furthermore, a water pump is arranged on the top of the antifreeze tank, and one side of the water pump is connected to the first antifreeze outlet through a first pipeline; an antifreeze return port and an antifreeze filling port are arranged on the antifreeze tank; and an antifreeze drain port is arranged at the bottom of the antifreeze tank.

[0010] Furthermore, the motor valve assembly includes a centralized liquid supply pipe, a liquid supply pipe connected to the centralized liquid supply pipe, and a plurality of motor valves arranged on the centralized liquid supply pipe; a second antifreeze liquid inlet is arranged at one end of the liquid supply pipe, and the second antifreeze liquid inlet is connected to the second antifreeze liquid outlet.

[0011] Furthermore, the motor valve assembly also includes a backflush port.

[0012] Furthermore, the antifreeze liquid detection assembly includes a centralized liquid return pipe and a plurality of flow meters arranged on the centralized liquid return pipe; a centralized liquid return pipe interface is arranged at one end of the centralized liquid return pipe.

[0013] Furthermore, the cooling water inlet assembly includes a factory cooling water inlet pipe, a first cooling water supply pipe and a second cooling water supply pipe connected to the bottom of the factory cooling water inlet pipe; a factory cooling water inlet is arranged at the top of the factory cooling water inlet pipe; and a DN40 motor valve is arranged on the first cooling water supply pipe.

[0014] Furthermore, a cooling water inlet filter is provided on the cooling water inlet pipe of the factory near the cooling water inlet of the factory; and a cooling water inlet pressure gauge is provided below the cooling water inlet filter.

[0015] Furthermore, the cooling water outlet assembly includes a factory cooling water outlet pipe, a first cooling water return pipe and a second cooling water return pipe connected to the factory cooling water outlet pipe; a factory cooling water outlet is arranged at one end of the factory cooling water outlet pipe; a cooling water return filter is arranged at one end of the factory cooling water outlet pipe close to the factory cooling water outlet.

[0016] The present invention also relates to a method for adjusting the temperature of a slicer bearing box, comprising the following steps:

[0017] S1. The antifreeze is output from the water pump to the heat exchanger, and the opening of the DN40 motor valve is set so that the temperature of the antifreeze output from the heat exchanger is X;

[0018] S2, setting the temperature of the four temperature sensors on the four bearing boxes of the slicer to Y, and the Y value is greater than X;

[0019] S3. The equipment starts to run, and the antifreeze at X degrees Celsius enters the four bearing boxes of the slicer through the four-way motor valves. The opening of the four-way motor valves is kept at 100% for the first 10 minutes of the operation of the bearing boxes. After 10 minutes of operation, the four temperature sensors feedback the temperature. When the temperatures fed back by the four temperature sensors show different values, the four motor valves adjust their respective openings to control the flow of the antifreeze through the bearing boxes so that the final temperature values ​​fed back by the four temperature sensors are the same.

[0059] See also Fig. 9 and Fig.10 , respectively, are a schematic diagram of the device of the present invention being assembled on the bearing box of a slicer and a working principle diagram. The method of adjusting the temperature of the bearing box using the device of the present invention is as follows:

[0060] (1) The antifreeze liquid is output from the water pump 11 to the heat exchanger 21, and the opening of the DN40 motor valve is set so that the temperature of the antifreeze liquid output from the heat exchanger 21 is X (the optimal temperature of the antifreeze liquid output from the heat exchanger in this embodiment is 20°C).

[0061] The DN40 motor valve is only involved in the control of the "total temperature sensor", and the sensing temperature of the "total temperature sensor" is the temperature of the antifreeze fluid output from the heat exchanger 21. By controlling the cooling water flow rate of the factory cooling water entering the heat exchanger 21, the temperature of the "total temperature sensor" is controlled at X.

[0062] (2) Set the temperature Y of "temperature sensor 1", "temperature sensor 2", "temperature sensor 3" and "temperature sensor 4" to a value greater than X. (The optimal value of temperature Y in this embodiment is 22-23°C)

[0063] (3) When the equipment starts to operate, the antifreeze at X degrees Celsius enters the bearing box 1, bearing box 2, bearing box 3, and bearing box 4 through "motor valve 1", "motor valve 2", "motor valve 3", and "motor valve 4" respectively. During the first 10 minutes of the operation of the bearing box, the opening of the 4 motor valves is kept at 100%; after 10 minutes of operation, "temperature sensor 1", "temperature sensor 2", "temperature sensor 3", and "temperature sensor 4" feedback the temperature. At this time, the temperature feedback from each temperature sensor is the temperature of each bearing box.

[0064] (4) When the temperatures fed back by "temperature sensor 1", "temperature sensor 2", "temperature sensor 3" and "temperature sensor 4" are different, "motor valve 1", "motor valve 2", "motor valve 3" and "motor valve 4" adjust their respective openings to control the flow of antifreeze liquid through the bearing box. The opening of the 4-way motor valve in this embodiment is between 35% and 100%.

[0065] Antifreeze with different flow rates has different cooling effects on each bearing box, making the final feedback temperatures of "temperature sensor 1", "temperature sensor 2", "temperature sensor 3" and "temperature sensor 4" basically the same, thereby ensuring that each bearing box maintains basically consistent temperature conditions during rotation.

[0066] The present invention has been described in detail above. The above description is only a preferred embodiment of the present invention and should not limit the scope of implementation of the present invention. That is, all equivalent changes and modifications made within the scope of this application should still fall within the scope of the present invention.
