[0030] Technologies, methods, and apparatus known to ordinary technicians in the relevant art may not be discussed in detail, but where appropriate, these technologies, methods, and apparatus should be considered part of the specification.

[0031] like Figure 1As shown, a roller grinder cooling device comprises a water pool 1, which is in a rectangular or square shape that is easy to dig or store water. The water pool 1 is used to store cooling water. The water pool 1 and the grinder 2 are fixedly connected through a water pipeline 4, and the water pipeline 4 extends from underground to above ground; an electromagnetic valve 5, which is arranged on the water pipeline 4; a water level gauge 6, which is arranged at the middle and upper part of the side wall of the water pool 1; an operation panel, which is arranged on the grinder 2, and the operation panel is provided with an opening and closing function of the electromagnetic valve 5; and a control cabinet, which comprises a PLC, which is electrically connected to the electromagnetic valve 5 and the water level gauge 6 respectively, and the PLC controls the operation of the grinder 2 and the electromagnetic valve 5 according to the preset water level value and the detected water level data.

[0032] In the roller grinder cooling device according to the embodiment of the utility model, the device is mainly composed of a water pool 1, a water pipeline 4 and an electromagnetic valve 5 arranged underground, and an operating panel and a control cabinet arranged on the ground. The automatic opening and closing of the roller grinding cooling water 3 is achieved through the cooperation of the ground control device and the underground electromagnetic valve 5.

[0033] The electromagnetic valve 5 can be opened or closed quickly, which is very beneficial for the control of cooling devices that require rapid response. Through electrical signal remote control, the electromagnetic valve 5 can be operated remotely, which improves the convenience and safety of operation, avoids the inefficiency of one person monitoring and one person going down to open the valve, and has low power consumption, which can save energy in long-term use.

[0034] In some specific embodiments, the water level meter 6 is arranged at a distance of 10 to 15 cm from the top of the side wall of the pool 1. Compared with being installed at the bottom of the pool 1 or near the water surface, the side wall 10 to 15 cm away from the top of the pool 1 is less disturbed by the liquid. This helps to provide more stable measurement readings, especially when the liquid in the pool 1 flows frequently or fluctuates greatly. The contact between the roller and the grinding wheel will generate a large amount of heat, and accordingly, the water temperature will be greatly increased. Installing the water level meter 6 on the side wall can avoid direct contact with high-temperature liquid and reduce the risk of equipment damage and personal injury. In addition, the side wall installation also facilitates rapid intervention and repair in emergency situations. Whether the pool 1 is round, square or irregular in shape, the position in the middle and upper part of the side wall can adapt to different installation requirements.

[0035] In some specific embodiments, the water pool 1 and the electromagnetic valve 5 are arranged underground. Placing the water pool 1 and the electromagnetic valve 5 underground can make full use of the underground space and avoid occupying the ground space. At the same time, this design also helps to reduce the footprint of the device on the ground and improve the space utilization rate. The underground environment usually has a relatively stable temperature, which is particularly important for the water pool 1 and the valve system that need constant temperature control. The underground environment can avoid the influence of high and low temperatures on equipment and pipelines, and extend the service life of the equipment.

[0036] On the basis of the above embodiments, a water supply pump is also provided on the water delivery pipeline. The water supply pump can quickly replenish the water required by the cooling device in a short time to ensure the stable operation of the device. It can also automatically adjust the water pressure according to the needs of the device to maintain the stability of the water flow inside the device, which can reduce equipment damage caused by poor water flow or unstable water pressure. The automatic detection and protection function of the water supply pump can timely detect and handle abnormal conditions in the device.

[0037] In some specific embodiments, a temperature sensor is also provided on the side wall of the middle depth of the pool 1. The temperature sensor can monitor the water temperature in the pool 1 in real time to ensure that the cooling device operates within a set temperature range. Accurate temperature monitoring helps ensure that the cooling device operates in the best working state, thereby improving cooling efficiency.

[0038] On the basis of the above embodiment, the electromagnetic valve 5 and the water level gauge 6 are detachable structures. The detachable structure makes the installation of the electromagnetic valve 5 and the water level gauge 6 more convenient, and can be flexibly installed in the corresponding position according to the specific use scenario and needs. In the process of maintenance and overhaul, there is no need to disassemble the entire system, and only the electromagnetic valve 5 or the water level gauge 6 needs to be removed separately, which greatly reduces the difficulty and cost of maintenance.

[0039] In some specific embodiments, an inlet pipe and a drain pipe are provided on the outer wall of the pool 1, and an inlet valve and a drain valve are provided on the inlet pipe and the drain pipe, respectively. The inlet valve and the drain valve can accurately control the inlet and outlet of water flow, ensuring that the water volume and water level in the pool 1 are maintained within a set range. The inlet valve and the drain valve are connected and controlled with a PLC and a sensor, so that remote operation and monitoring can be easily realized, which enables the operator to understand the operating status of the system in real time and make adjustments as needed.

[0040] On the basis of the above embodiment, a flow meter is provided on the electromagnetic valve 5. Through real-time flow data, the operator can timely adjust the valve opening or other control parameters to optimize the operation process of the cooling device. The flow meter can detect abnormal flow changes, such as sudden increase or decrease in flow, which can serve as an early warning signal of potential system failure. By timely discovering problems and taking measures, serious consequences such as device damage and production interruption can be avoided.

[0041] In some specific embodiments, one end of the water inlet pipe and the drain pipe are connected to the bottom of the pool 1. When both the water inlet pipe and the drain pipe are connected to the bottom of the pool 1, the water level of the pool 1 can be more effectively controlled. By adjusting the water inlet flow rate and the drain flow rate, the water level can be quickly adjusted to a desired level to prevent the water level from being too high or too low and causing damage to the pool 1. Connecting the drain pipe to the bottom of the pool 1 can ensure that the water in the pool 1 can be drained more quickly when draining. Bottom drainage helps to reduce the residual water in the pool 1, especially when the pool 1 needs to be completely emptied.

[0042] On the basis of the above embodiment, an alarm is further included, and the water level meter 6 is electrically connected to the alarm. The water level alarm can monitor the water level in the cooling device in real time, and when the water level exceeds or falls below a preset safety threshold, an audible or visual alarm signal can be immediately issued to remind the operator to take timely measures.

[0043] The utility model has at least the following advantages:

[0044] (1) The water level meter 6 can monitor the water level in the cooling device in real time to ensure that the water level in the system remains at an optimal state, thereby avoiding affecting the cooling effect or equipment safety due to excessively high or low water levels.

[0045] (2) Combined with the remote control function of the electromagnetic valve 5, the cooling system can be managed automatically, reducing the need for manual monitoring and adjustment.

[0046] (3) By precisely controlling the flow of water levels, the cooling process can be optimized, unnecessary energy consumption can be reduced, and the energy efficiency ratio of the system can be improved.

[0047] (4) The water level gauge 6 can prevent the cooling water 3 from overflowing. At the same time, the electromagnetic valve 5 can automatically close when the water level is too low to avoid the pump running dry and protect the equipment from damage.

[0048] (5) The combination of the solenoid valve 5 and the water level meter 6 makes system maintenance easier because they can provide real-time data about the system status.

[0049] (6) Automated control reduces the possibility of human error and can quickly cut off and drain the cooling water supply in an emergency, improving the safety of the entire system.

[0050] (7) Automated water level control and fast-response electromagnetic valve 5 can reduce system failures caused by operational errors or delays and improve the reliability of the entire cooling system.
