It should be understood that the specific embodiments described herein are only used to explain this utility model and are not intended to limit this utility model.

[0026] like Figure 1 As shown in the figure, this utility model embodiment provides a temperature control system for a clinker crusher bearing, including an inlet pipe 1, a return pipe 2, and several clinker crusher bearing seats 3. A water-cooling main channel 4 is provided between the inlet pipe 1 and the return pipe 2, and the water-cooling main channel 4 passes through several of the clinker crusher bearing seats 3. A pressure difference exists between the inlet pipe 1 and the return pipe 2. Through the pressure difference between the inlet pipe 1 and the return pipe 2, water cooling is achieved for the clinker crusher bearing seats 3, that is, water cooling of the clinker crusher bearing. In addition, a temperature regulating channel 5 is connected to the water-cooling main channel 4. The temperature regulating channel 5 regulates the temperature by adjusting the flow rate entering the water-cooling main channel 4, thereby achieving temperature regulation and control of the clinker crusher bearing seats 3, that is, temperature regulation and control of the clinker crusher bearing.

[0027] In some embodiments, the temperature regulating channel 5 is connected to the water-cooling main channel 4 via a connecting channel 6. By controlling the flow rate into the connecting channel 6 through the temperature regulating channel 5, the flow rate into the water-cooling main channel 4 can be controlled.

[0028] In some embodiments, the water-cooled main channel 4 includes a first connection point 401, a second connection point 402, and a third connection point 403, with the third connection point 403 located between the first connection point 401 and the second connection point 402. The first connection point 401 is connected to the inlet pipe 1, the second connection point 402 is connected to the return pipe 2, and the third connection point 403 is connected to the connecting channel 6. With this configuration, the flow rate of the water-cooled main channel 4 itself serves as the primary cooling flow rate, while the flow rate from the temperature regulation channel 5 to the connecting channel 6 and then into the water-cooled main channel 4 serves as the temperature regulation flow rate.

[0029] In some embodiments, a plurality of clinker crusher bearing seats 3 are arranged in parallel on the water-cooled main channel 4, and the plurality of clinker crusher bearing seats 3 are all located between the third connection point 403 and the second connection point 402. Figure 1 Taking two clinker crusher bearing seats 3 as an example, there can actually be more clinker crusher bearing seats 3, which is not limited here.

[0030] In some embodiments, a first valve 7 is provided on the water-cooled main channel 4, and the first valve 7 is located between the first connection point 401 and the third connection point 403. The first valve 7 serves as a total flow valve and is normally open during operation.

[0031] In some embodiments, a second valve 8 is provided on the connection channel 6. The second valve 8 is closed when the temperature regulation channel 5 is not required to operate; the second valve 8 is opened when the temperature regulation channel 5 is required to operate, so that the flow rate of the temperature regulation channel 5 can enter the water-cooled main channel 4.

[0032] In some embodiments, the temperature regulating channel 5 includes a fourth connection point 501, a fifth connection point 502, and a sixth connection point 503, wherein the sixth connection point 503 is located between the fourth connection point 501 and the fifth connection point 502; the fourth connection point 501 is connected to the water tank 9, the fifth connection point 502 is connected to the water tank 9, and the sixth connection point 503 is connected to the connecting channel 6. Under the above configuration, the temperature regulating channel 5 supplies water through the water tank 9.

[0033] In some embodiments, the temperature regulating channel 5 is equipped with a first water pump 10 and a third valve 11. The first water pump 10 is located between the fourth connection point 501 and the sixth connection point 503, and the third valve 11 is located between the fifth connection point 502 and the sixth connection point 503. Based on the above configuration, water can be pumped from the water tank 9 by the first water pump 10 and transported to the connecting channel 6 and then to the water-cooled main channel 4. At the same time, the flow rate to the water-cooled main channel 4 can be controlled by the third valve 11, thereby controlling the flow rate of water transported to the temperature regulating channel 5.

[0034] In some embodiments, the water tank 9 is connected to a water supply channel 12, one end of which is connected to the water inlet pipe 1, and the other end of which is connected to the water tank 9. A second water pump 13 is installed on the water supply channel 12. Based on the above configuration, water can be transported from the water inlet pipe 1 to the water tank 9 via the second water pump 13.

[0035] In some embodiments, a sensor float 14 is installed inside the water tank 9, and the sensor float 14 is connected to an external control device 15. Based on the above configuration, the liquid level in the water tank 9 can be obtained through the sensor float 14, and then the second water pump 13 can be controlled to add or stop water to the water tank 9 based on whether the liquid level meets the requirements. The external control device 15 can be a computer, and the specific logic for controlling the addition or stop of water is based on whether the liquid level meets the requirements. For example, the water is stopped when the preset liquid level is reached, and water is added when the preset liquid level is not reached. This is existing technology and will not be elaborated here.

[0036] This invention aims to ensure that the bearing temperature meets requirements by designing a water-cooling mode for the bearing cooling system, thereby creating a temperature control system. The working process of this invention will be described in detail below.

[0037] During operation, the first valve 7 is normally open.

[0038] When the bearing operating temperature is below 65 degrees, the first water pump 10, the second water pump 13, the second valve 8, and the third valve 11 are adjusted to the closed state; the temperature control system relies on the pressure difference between the inlet pipe 1 (0.6 MPa) and the return pipe 2 (0.4 MPa) of the pipeline network to achieve water cooling.

[0039] When the bearing temperature exceeds 65 degrees Celsius, the first water pump 10 starts, the second valve 8 fully opens, and the third valve 11 automatically adjusts its opening according to the bearing temperature. The opening of the third valve 11 regulates the flow rate through the second valve 8, thereby achieving the goal of controlling the bearing temperature. This control loop can be a PID automatic control system, enabling constant temperature control. PID stands for Proportional, Integral, and Differential, representing three control algorithms. Combining these three algorithms can effectively correct deviations in the controlled object, thus achieving a stable state. Specific PID technology is existing and will not be elaborated upon here.

[0040] The second water pump 13 supplies water to the water tank 9. The start and stop of the second water pump 13 are automatically controlled by the liquid level of the sensing float 14. For example, the water will automatically stop when the water level is higher than 2.5m and automatically add water when the water level is lower than 1m.

[0041] In summary, this utility model proposes a temperature control system for clinker crusher bearings, which allows the water-cooling main channel to pass through the clinker crusher bearing housing, thereby removing heat from the clinker crusher bearings and cooling them down. Furthermore, the flow rate into the water-cooling main channel is adjusted through a temperature regulation channel, thereby achieving temperature regulation and control of the clinker crusher bearings.

[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the scope of this utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model. Contents not described in detail in this specification are prior art known to those skilled in the art.
