[0024] Example:
[0025] See also Figure 1-Figure 2This embodiment provides a heating device for a roller grinder carriage bed, comprising a supply pipeline 4, a heating pipeline unit 6, a return pipeline 8, a pumping device 11 and a heater 14, wherein the outlet end of the heater 14 is connected to the inlet end of the heating pipeline unit 6 through the supply pipeline 4, the outlet end of the heating pipeline unit 6 is connected to the inlet end of the pumping device 11 through the return pipeline 8, and the outlet end of the pumping device 11 is connected to the inlet end of the heater 14; that is, the supply pipeline 4, the heating pipeline unit 6, the return pipeline 8, the pumping device 11 and the heater 14 form a The medium circulation loop is formed, the heater 14 is used to heat the medium in the pipeline, and the heating pipeline unit 6 is used to heat the carriage bed 15 of the roller grinder. Specifically, the carriage bed 15 is heated by the heat radiation of the medium in the heating pipeline unit 6; the medium in the heating pipeline unit 6 will cool down after completing the heating of the carriage bed, and the cooled medium will re-enter the heater through the reflux pipeline 8 to be heated, and then be transported to the heating pipeline unit, so that the carriage bed 15 is continuously heated in this reciprocating manner to ensure that the temperature of the carriage bed is within the target range.
[0026] See also Figure 1 The heating device also includes a high-level oil tank 2, which is connected to the return line 8 through an expansion branch 9, and is connected to the supply line 4 through an exhaust line 3. The high-level oil tank 2 is provided with an exhaust hole and a liquid level detection component. Specifically, the high-level oil tank 2 stores medium oil for circulation heating, and the high-level oil tank 2 provides medium oil to the return line 8 through the expansion branch 9 to achieve the normal operation of the circulation loop; since the medium oil will expand and contract in the circulation loop, the return line 8 is connected to the high-level oil tank 2 through the expansion branch 9 to eliminate the influence of the medium oil expansion and contraction on the circulation loop, and the changes caused by the expansion and contraction of the medium oil will be adjusted through the liquid level changes in the high-level oil tank 2, and the liquid level changes in the high-level oil tank 2 are detected by the liquid level detection component. Furthermore, the supply pipeline 4 is connected to the high-level oil tank 2 through the exhaust pipeline 3. The bubbles generated by the heating of the medium oil can enter the high-level oil tank 2 through the exhaust pipeline 3 and then be discharged through the exhaust hole to prevent the bubbles from affecting the circulation loop.
[0027] Preferably, the high-position oil tank 2 is located at the highest point in the heating device. Specifically, in this embodiment, the high-position oil tank 2 is more than 1.5 meters higher than the highest point in the circulation loop, and the exhaust pipe 3 is connected to the highest point of the supply pipe 4, so that the bubbles in the supply pipe 4 gather at the highest point and are discharged into the high-position oil tank 2 through the exhaust pipe 3.
[0028] See also Figure 1A temperature detection element 13 is provided at the inlet end of the pumping device 11 and the outlet end of the heater 14, wherein the temperature detection element 13 at the outlet end of the heater 14 is used to detect the temperature of the medium oil output by the heater, and the temperature detection element 13 at the inlet end of the pumping device 11 is used to detect the temperature of the medium oil entering the pumping device 11.
[0029] Furthermore, a pressure detection component 12 is provided at the outlet end of the pumping device 11 , and the pressure detection component is used to detect the output pressure of the pumping device 11 .
[0030] See also Figure 1 The heating device also includes a control unit 1, and the pressure detection component 12, the temperature detection component 13, the heater 14, the pumping device 11, and the liquid level detection component on the high-level oil tank 2 are all electrically connected to the control unit 1. The control unit 1 is electrically connected to the pumping device 11 to achieve the effect of controlling the output pressure of the pumping device 11; the control unit 1 is electrically connected to the liquid level detection component to achieve the effect of detecting and obtaining the liquid level of the high-level oil tank 2, and an alarm can be issued according to the upper and lower limits of the liquid level; the control unit 1 is electrically connected to the temperature detection component 13 and the heater 14 to realize the linkage control of the heating intensity of the heater 14. When it is detected that the medium oil temperature output by the heater 14 is lower than the set temperature, the heater 14 can be controlled to increase the heating intensity. When it is detected that the medium oil temperature output by the heater is higher than the set temperature, the heater 14 can be controlled to reduce the heating intensity to achieve the purpose of controllable heating temperature of the carriage bed. After actual application verification, such control can achieve that the error between the medium oil temperature at the outlet of the heater and the set temperature does not exceed + / -1°C; in this embodiment, the temperature of the medium oil is controlled at about 30°C to ensure that the lubricating fluid of the roll grinder is at a suitable temperature, which can effectively ensure the stability of movement, avoid vibration marks, horizontal lines and other roller surface defects caused by grinding, and ensure the quality of roller use.
[0031] See also Figure 1 The heating device further comprises a bypass branch 5, which is connected in parallel with the heating pipeline unit 6 between the supply pipeline 4 and the return pipeline 8. The bypass branch 5 comprises a stop valve 7, which controls the on-off of the bypass branch 5. When the heating pipeline unit 6 needs maintenance, the bypass branch 5 can be opened, and the medium between the supply pipeline 4 and the return pipeline 8 can be circulated through the bypass branch 5, and the heating device does not need to be shut down (after the heating device is shut down, the medium needs to be reheated, which will consume a lot of energy, so the heating device is generally not shut down for maintenance).
[0032] Preferably, in this embodiment, stop valves 7 are provided at both ends of the heating pipeline unit 6, on the exhaust pipeline 3, on the supply pipeline 4, on the return pipeline 8, and between the heater and the pumping device to facilitate the subsequent maintenance and overhaul of the heating device.
[0033] See also Figure 2 The heating pipeline unit 6 includes a plurality of heating branches 6.1 connected in parallel between the supply pipeline 4 and the return pipeline 8. The advantages of arranging the plurality of heating branches 6.1 in parallel are as follows: the length of the heating branch 6.1 at the carriage bed is short, the temperature difference between the inlet and outlet ends of the heating branch 6.1 is relatively small, and the medium oil temperature at the same position in each heating branch 6.1 is consistent, which can ensure the uniformity of heating the carriage bed; if a U-shaped pipeline is used, the length of the pipeline is very long, resulting in a large temperature difference between the head end and the tail end, which will lead to the problem of uneven heating of the carriage bed.
[0034] See also Figure 1 The return pipeline 8 is provided with an expansion joint 10, and the expansion joint 10 is located between the inlet end of the pumping device 11 and the expansion branch 9. The expansion joint 10 can compensate for the deformation of the pipeline due to thermal expansion and contraction.
[0035] Preferably, the dielectric oil in this embodiment is electrolytic oil.
[0036] The heating device in this embodiment can heat the carriage bed of the roll grinder to solve the problem that the viscosity of the roll grinder lubricant increases in a cold environment, causing the carriage to shake in its reciprocating motion; the heating device keeps the carriage bed at a suitable temperature, that is, ensures that the roll grinder lubricant is at a suitable kinematic viscosity, achieves the effect of fully lubricating the roll grinder, and ensures the stability of the carriage movement and the accuracy of the roll grinding. The heating pipeline unit is provided with multiple parallel heating branches, which can achieve the effect of uniform heating of the carriage bed, prevent the carriage bed from being heated unevenly, and affect the stability of the movement. The heating device in this embodiment is simple, practical, economical and environmentally friendly, and can effectively solve the problem of poor operating efficiency of the grinder at low temperature and poor surface quality of the ground roll, and can effectively improve the grinding accuracy, surface quality and efficiency of the grinder, reduce the rework rate of grinding, and thus ensure the quality of the product.
