This invention relates to drug nebulizers, specifically disclosing a wearable respiratory medicine drug nebulizer, comprising a housing and a handle fixedly connected to its lower end. The housing has an internal air collecting tube and an external exhaust port extending into the air collecting tube, with a breathing mask connected to the exhaust port. An elastic cord for wearing the breathing mask on the patient's face is connected to the housing, and a medicine bottle is mounted at the upper end of the housing. An air compressor is installed inside the housing. The air collecting tube is connected to the medicine bottle via an air delivery tube, and the middle part of the air delivery tube is connected to the exhaust end of the air compressor. This invention results in fewer droplets in the breathing mask during patient exhalation, reducing medication waste; and more droplets in the breathing mask during patient inhalation, facilitating the inhalation of more medication-containing droplets, thereby improving medication utilization.

This invention discloses a die-casting release agent recovery device, relating to the field of die-casting release machine recycling technology. It includes a processing device with a guide shell on one side. A fixed frame is fixedly connected to the guide shell, and a first protective shell is fixedly connected to the fixed frame. A sliding frame is slidably connected to the first protective shell, and an oil-absorbing ring is fixedly connected to the side of the sliding frame away from the first protective shell. The guide shell is used to scrape off floating oil from the oil-absorbing ring. This invention utilizes the reciprocating motion of the oil-absorbing ring to contact and absorb floating oil from the waste liquid surface. Even under conditions of strong surface disturbance in the waste liquid, effective adsorption of floating oil can be achieved. Compared with the prior art of directly extracting floating oil, this invention utilizes the oil-absorbing characteristics of the oil-absorbing ring to more accurately identify and adsorb the oil layer, reducing water absorption while improving the purity and overall recovery efficiency of the recovered release agent.

This invention relates to the field of electric drive control technology for high-pressure, high-displacement pumps in oilfield fracturing operations. It discloses a vehicle-mounted high-power electric drive system. The high-voltage power distribution unit is connected to the power input unit and consists of a load switch and a circuit breaker connected in series. The load switch is connected to a fuse to output low-voltage control power. The circuit breaker is sequentially connected to a phase-shifting transformer and a medium-voltage frequency converter to provide the main power supply for the medium-voltage motor of the fracturing pump. The input terminal of the pre-charge unit is connected to the load switch, and the output terminal is connected to the phase-shifting transformer. A cooling system provides cooling for the phase-shifting transformer and the medium-voltage frequency converter. This invention also discloses a control method for the vehicle-mounted high-power electric drive system. This vehicle-mounted high-power electric drive system and its control method enable the integrated vehicle-mounted operation of a high-power, high-displacement fracturing pump skid and its drive system in the fracturing engineering field, significantly reducing on-site work intensity, lowering operating costs, and mitigating on-site risks.
