Abstract
Description
Technical field:
[0001] The utility model relates to the technical field of industrial water circulation, in particular to an industrial cooling water circulation system with a pipeline self-switching component which has a reasonable structure and is easy to operate and can meet processing cooling requirements. Background technology:
[0002] In the industrial production process, a large amount of water is needed to cool the equipment. The existing cooling water circulation supply device is equipped with a water tank. The water tank is first filled with water. After the water tank passes through the filter, the water is pumped by the water supply pump to the workshop equipment. After the workshop equipment uses water to cool down, the water is recycled to the water tank. At this time, the water is hot and cannot be further used for cooling. Therefore, the return water in the water tank needs to be sent to the refrigerator for cooling until the return water drops to the set value, and then it is sent to the workshop by the water pump for recycling.
[0003] At present, when the water in the water tank passes through the filter, the filter is easily blocked, resulting in a decrease in the flow of water sent to the workshop in the entire system, causing the equipment to be unable to cool down in time. Manually opening the backup bypass pipeline for water supply after waiting for the workshop personnel to report will cause equipment failure due to prolonged water outage time, generating a large amount of waste. Summary of the invention:
[0004] In view of the shortcomings and deficiencies in the prior art, the utility model proposes an industrial cooling water circulation system with a pipeline self-switching component which has a reasonable structure, is easy to operate and can meet the processing cooling requirements.

[0007] A filter is arranged on the pipeline between the bypass water supply pipeline and the water supply tank of the utility model, which is used to filter out impurities in the water in time to avoid damaging the equipment after being pumped to the water pump or subsequent equipment.
[0008] The bypass water supply pipeline of the utility model is also provided with a solenoid valve, which is connected to the PLC controller and is used to open or close the bypass water supply pipeline under the control of the PLC controller. The solenoid valve is arranged on the pipeline between the filter of the bypass water supply pipeline and the water outlet of the water supply tank.
[0009] The PLC controller of the utility model is also connected with an audible and visual alarm and a wireless communication circuit. The wireless communication circuit adopts a Bluetooth communication module to realize sending an alarm signal to an external handheld management terminal.
[0010] The utility model provides a temperature sensor connected to a PLC controller in the water supply tank, and is provided with a cooling water return pipeline. The front end of the cooling water return pipeline is connected to the outlet of the water supply tank, and the rear end is connected to the water return pipeline. The cooling water return pipeline is provided with a solenoid valve and a cooling water return pump. A filter is provided between the cooling water return pump and the solenoid valve. The cooling water return pump is connected to the PLC controller.
[0011] When the utility model is working, by arranging a flow sensor at the rear end of the filter of the water pumping pipeline in the workshop, the change of the current water flow pumped to the workshop can be understood in real time, and the lower limit of the flow can be set in advance through the PLC controller, so that when the water flow pumped to the workshop is reduced to the lower limit of the flow, the solenoid valve and the bypass water supply pump on the bypass water supply pipeline are automatically opened through the PLC controller, and the bypass water supply pipeline is enabled to transport cooling water to the workshop in time. At the same time, an alarm signal is output, including an audible and visual alarm signal located on site and a wireless alarm signal of an external terminal, so as to prompt the maintenance personnel to deal with the fault in time; during the water supply process, the PLC controller can also detect the water temperature in the water supply tank through the temperature sensor. If the water temperature does not meet the cooling requirement of the workshop, it can be sent to the refrigerator again through the cooling return pipeline for cooling, thereby reducing the loss of cooling efficiency when the ambient temperature is high.
