[0001] This application relates to the field of cement production equipment technology, and in particular to a temperature regulating device for an oil station. Background Technology
[0002] The white cement is produced using advanced domestic dry-process technology. The product mainly comes in three grades: Baichuan brand P·W-1 32.5, P·W-1 42.5, and P·W-1 52.5 white cement.

[0003] However, after the vertical mill has been used for a long time, the oil temperature will be high, which will significantly reduce the cooling effect of the vertical mill; while in winter and other periods when the outside temperature is low and the vertical mill is not used for a long time, the oil temperature will be low and the flow will be poor, resulting in oil leakage problems. Utility Model Content

The heat exchanger is disposed on the oil station and located between the oil inlet pipelines. Cooling oil in the oil station flows through the oil inlet pipeline to the heat exchanger, and then through the heat exchanger and the oil inlet pipeline to the cooling system of the vertical mill. A temperature probe is installed at the oil outlet of the oil station to measure the temperature of the output oil.

[0020] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0021] This application discloses a gas station temperature control device. (Refer to...) Figure 1 and Figure 2 The oil station temperature regulation device includes an oil inlet pipe 2 and a heat exchanger 3 installed between the vertical mill and the oil station 1. The heat exchanger 3 is installed on the oil station 1 and located between the oil inlet pipe 2. The cooling oil in the oil station 1 passes through the oil inlet pipe 2 to the heat exchanger 3, and then through the heat exchanger 3 and the oil inlet pipe 2 to the cooling system of the vertical mill. A temperature probe is installed at the oil outlet of the oil station 1 to measure the temperature of the output oil. It also includes a water supply pipe 4, which is connected to the water inlet of the heat exchanger 3. The water supply pipe 4 is used to inject hot or cold water into the heat exchanger 3 to regulate the oil temperature.
[0022] When the oil temperature is below or above the design range, the temperature probe sends the temperature feedback to the operator. Then, hot or cold water is injected into the heat exchanger 3 through the water supply pipe 4 to achieve heat exchange with the oil, thereby heating or cooling the oil and keeping the oil temperature within the design range. This ensures the cooling effect on the grinding roller and facilitates the flow of the oil.
[0023] Reference Figure 2 and Figure 3 When heat exchanger 3 is used for a long time, a lot of scale tends to form in the chamber where hot water is injected, which affects the heat exchange effect of the heat exchange plates. Therefore, in this embodiment, heat exchanger 3 is provided with an air inlet pipe 5, and multiple branch pipes 6 are provided on the air inlet pipe 5. The branch pipes 6 enter between the heat exchange plates of heat exchanger 3 and are located in the water chamber. The air inlet pipe 5 is used to input compressed air and inject it into the water chamber through the branch pipes 6 to remove the scale on the heat exchange plates. When cleaning the scale on the heat exchange plates, a weak acidic liquid is first injected through the water supply pipe 4. Then, the air inlet pipe 5 is connected to an air pump, etc. The air pump injects compressed air between the heat exchange plates, causing the weak acidic liquid to generate a large number of bubbles between the heat exchange plates. When the bubbles burst, they act on the scale, thereby improving the cleaning effect of the acidic liquid on the scale. At the same time, the scale removal efficiency is improved.
[0024] Reference Figure 2 and Figure 3 In this embodiment, the air inlet pipe 5 includes a first pipe 51 parallel to the length direction of the air exchanger and a second pipe 52 parallel to the width direction of the heat exchanger 3. Multiple second pipes 52 are provided and are parallel to each other. Branch pipes 6 are provided on the second pipes 52 and are provided along the length direction of the second pipes 52. The first pipe 51 is used to connect to the second pipes 52. Under the action of the second pipes 52, the branch pipes 6 are added, thereby increasing the range of action of the branch pipes 6, and thus improving the cleaning effect and efficiency of scale.
[0025] Reference Figure 2 and Figure 3 To further improve the agitation effect of compressed gas on acidic liquid, branch pipe 6 is a telescopic pipe, and multiple air outlets 7 are opened on the side wall of branch pipe 6. The air outlets 7 are evenly distributed along the side wall of branch pipe 6. By sliding the telescopic pipe, the overall length of branch pipe 6 is extended, so that the effective range of branch pipe 6 reaches the bottom of heat exchange plate, which facilitates the injection of compressed gas into the bottom of heat exchange cavity, thereby improving the effective range of compressed gas and the agitation effect on acidic liquid.
[0026] Reference Figure 2 and Figure 3 In this embodiment of the application, the branch pipe 6 includes multiple telescopic pipes that are nested together, the air outlet 7 is opened on the side wall of the telescopic pipe, and the branch pipe 6 also includes a driving member for driving the telescopic pipe to extend or retract.
[0027] Reference Figure 2 and Figure 3 The driving component includes a winding shaft 8 rotatably mounted on the second pipe body and a winding rope 9 wound on the winding shaft 8. The length direction and rotation axis of the winding shaft 8 are both parallel to the length direction of the second pipe body. The winding rope 9 is connected to the end telescopic pipe. The winding shaft 8 winds up or unwinds the winding rope 9 to adjust the length of the branch pipe 6.
[0028] When adjusting the length of the branch pipe 6, rotate the winding shaft 8. The winding shaft 8 winds up or releases the winding rope 9, thereby causing the telescopic pipe to slide and adjusting the length of the branch pipe 6. The operation is simple and convenient.
[0029] Reference Figure 2 and Figure 3 In this embodiment, the second tube is slidably mounted on the fixing rod 10, and the end of the take-up shaft 8 is provided with an insertion groove for the fixing rod 10 to be inserted. The fixing rod 10 is a polygonal rod. After the length of the branch tube 6 is adjusted, the fixing rod 10 is slidably inserted into the insertion groove to fix the take-up shaft 8, so as to fix the branch tube 6 at the designed position. The operation is simple and convenient.
[0030] Reference Figure 2 and Figure 3 In this embodiment, a baffle 11 is hinged to the end of the telescopic tube. The rotation axis of the baffle 11 is perpendicular to the axis of the telescopic tube. The area of the baffle 11 is larger than the area of the telescopic tube port. The free end of the winding rope 9 is fixedly mounted on the baffle 11. A sealing gasket 12 is provided on the surface of the baffle 11 that abuts against the telescopic tube. When the heat exchanger 3 is performing heat exchange operations, the winding shaft 8 winds up the winding rope 9. The winding rope 9 drives the telescopic tube to slide by pulling the baffle 11. At this time, the baffle 11 closes the port of the telescopic tube and applies tension to reduce the possibility of heat exchange liquid entering the branch pipe 6.
[0031] The implementation principle of a gas station temperature regulation device according to an embodiment of this application is as follows:
[0032] When the oil temperature is below or above the design range, the temperature probe sends the temperature feedback to the operator. Then, hot or cold water is injected into the heat exchanger 3 through the water supply pipe 4 to achieve heat exchange with the oil, thereby heating or cooling the oil and keeping the oil temperature within the design range. This ensures the cooling effect on the grinding roller and facilitates the flow of the oil.
[0033] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
