The utility model relates to the technical field of dust collection fans, in particular to a dust collection fan energy-saving device capable of adjusting operation conditions in real time, which comprises a dust collector, a connecting pipeline and an air duct are arranged on one side of the dust collector, a first dust collection mechanism and a second dust collection mechanism are arranged at one end of the connecting pipeline, and the first dust collection mechanism comprises an electric valve. A dust collection point is arranged on one side of the electric valve, and a dust concentration sensor is arranged in the dust collection point. According to the dust collection fan energy-saving device capable of adjusting the operation working condition in real time, the dust concentration sensor is additionally arranged, the effect of recognizing the dust raising amount is achieved, the electric valve is additionally arranged, the effect of controlling the air inlet amount is achieved, and the dust concentration sensor, the variable-frequency speed adjusting device and the intelligent control unit are used in cooperation; by means of the structure, the power of the dust collecting fan can be automatically adjusted, and therefore the purpose of saving energy is achieved.

A high-speed kneader for producing composite materials relates to the field of kneader technology and solves the problem of easy oxidation and performance degradation of composite materials during the kneading process in existing technologies. It includes a tank body, with a feeding tank connected to the bottom of the tank body. A discharge pipe is connected to the lower end of the feeding tank. An inlet pipe and a vacuum pipe are connected to the upper side wall of the tank body. A rotating shaft is coaxially rotatably connected to the tank body. The lower end of the rotating shaft is disposed inside the feeding tank. An air inlet is opened on the bottom end face of the rotating shaft, and multiple air outlets are evenly opened on the top side wall of the rotating shaft. An electric heating element is connected inside the rotating shaft, and multiple mixing blades are connected around the circumference of the rotating shaft. A material receiving plate is provided on the top of the feeding tank, and an air inlet pipe is connected to the side wall of the feeding tank. The beneficial effect is that it can inhibit the contact between materials and oxygen, improving the performance stability of composite materials.

The invention relates to the technical field of power systems, and particularly provides a method and device for automatically adjusting ring main unit dehumidifiers, a medium and equipment, and the method can comprise the steps: obtaining the total dehumidification power value of all dehumidifiers in the future time based on a pre-trained ring main unit power prediction model and historical data of a ring main unit; the dehumidification power of each dehumidifier is adjusted according to the power adjusting step length determined by the dehumidification demand weight of each dehumidifier; wherein the adjustment sum of the dehumidification power of all dehumidifiers does not exceed the total value of the dehumidification power; under the dehumidification power, the dehumidification efficiency of each dehumidifier in a preset time period is obtained; the dehumidification efficiency is compared with the expected efficiency, the dehumidification demand weight is optimized, and the optimized dehumidification demand weight is obtained; and the dehumidification power is automatically adjusted through the optimized dehumidification demand weight. According to the embodiment of the invention, power self-adjustment of the dehumidifier can be realized, and intelligent dehumidification of the ring main unit is realized.
