This utility model relates to a turbid circulating water pressurization system for a finishing mill, belonging to the field of mechanical equipment technology. It includes a main inlet pipe, the outlet of which is connected to the cooling circuit of the finishing mill. A centrifugal pump is installed on the main inlet pipe, driven by a variable frequency motor. The centrifugal pump pressurizes the turbid circulating water and pumps it into the cooling circuit of the finishing mill. An inlet butterfly valve, an inlet pressure gauge, and an inlet pressure sensor are installed on the inlet side of the main inlet pipe, and an outlet butterfly valve, an outlet pressure gauge, and an outlet pressure sensor are installed on the outlet side. The inlet pressure sensor, outlet pressure sensor, and variable frequency motor are connected to a PLC control cabinet. The inlet and outlet pressure sensors detect the water pressure at the inlet and outlet of the main inlet pipe and feed it back to the PLC control cabinet. Upon receiving the signal, the PLC control cabinet adjusts the speed of the variable frequency motor. This application can locally increase the turbid circulating water supply pressure of the finishing mill rolls, improve the cooling effect of the roll rings, and ensure the surface hardness of the roll rings.

This utility model discloses a pressurized coffee component extraction device, belonging to the field of coffee component extraction. The pressurized coffee component extraction device includes a coffee machine, a pressurized water inlet connected to the output end of the coffee machine, a filter pot disposed on the front of the coffee machine, the filter pot being fitted onto the surface of the pressurized water inlet, coffee powder stored inside the filter pot, a support being disposed at the bottom of the filter pot, and a transmission structure disposed on the surface of the coffee machine. The transmission structure utilizes the support to drive the filter pot upwards and change the distance between it and the pressurized water inlet. The transmission structure includes a connecting frame fixedly connected to the right side of the coffee machine. This utility model directly adjusts the impact force of the high-pressure water flow on the coffee powder by changing the distance between the filter pot and the pressurized water inlet. A smaller distance increases the water pressure and improves extraction efficiency; a larger distance reduces the pressure and avoids over-extraction, thus solving the problem of gradual concentration reduction caused by traditional fixed pressurization.
