3results about How to "Increase or decrease speed" patented technology

This application relates to the field of food processing equipment technology, and in particular to a quick-freezing tunnel utilization optimization system and method, comprising: a data acquisition module for real-time acquisition of product core temperature data, tunnel capacity data, tunnel cooling output data, and freezing time data in at least one quick-freezing tunnel; a data analysis module connected to the data acquisition module for constructing and storing a model reflecting the correlation between product core temperature and tunnel capacity, cooling output, and freezing time; and an optimization decision module connected to the data analysis module for inputting the currently acquired real-time tunnel operating parameters into the model, calculating the current tunnel utilization rate, and outputting optimization instructions for adjusting the tunnel operating parameters. This application can increase the feedback between quick-freezing tunnel operating parameters and product core temperature, thereby improving energy efficiency.

This utility model discloses an intelligent dissolved oxygen regulation device for a biological treatment tank, relating to the field of wastewater treatment technology. Specifically, it includes a water tank, within which an aeration disc and a dissolved oxygen analyzer are fixedly installed. A blower is located outside the water tank, and a frequency converter and controller are located outside the blower. An air supply pipe is fixedly installed at the output end of the blower, and a four-way fitting is fixedly connected to one end of the air supply pipe. An air plate is fixedly installed inside the aeration disc, and several sealing blocks are installed inside the air plate. Several fixing brackets are fixedly installed at the bottom of the air plate. This utility model uses a preset standard dissolved oxygen value and a dissolved oxygen analyzer to monitor the dissolved oxygen content in the wastewater. When the measured value at a certain time does not meet the preset standard value, the controller increases or decreases the blower's airflow and the frequency converter's speed, thereby adjusting the dissolved oxygen value in the water tank in a timely manner, facilitating stable wastewater treatment.

The utility model relates to the technical field of wool textile, in particular to a gilling machine speed change adjustable device which is characterized in that a connecting piece is arranged in the center of a bottom plate of a gilling machine, and a side plate at one end of a pay-off wheel is connected in a sliding groove in the connecting piece in a sliding mode. A plurality of blades are evenly arranged on the outer edge of the side plate, a speed increasing nozzle and a speed reducing nozzle are arranged in the sliding groove, the speed increasing nozzle and the speed reducing nozzle are communicated with the main air pipe through a speed increasing branch flow channel and a speed reducing branch flow channel respectively, and the speed increasing branch flow channel and the speed reducing branch flow channel are each provided with an electromagnetic valve. Wherein the airflow spraying direction of the speed increasing nozzle is along the rotation direction of the pay-off wheel, and the airflow spraying direction of the speed reducing nozzle is opposite to the rotation direction of the pay-off wheel. Therefore, the rotation speed of the pay-off wheel can be rapidly increased or decreased through cooperation of the two. The rotating speed of the pay-off wheel can adapt to the traction speed of a roller more quickly, and adverse effects are reduced.
