The invention relates to the technical field of grain drying equipment, in particular to a low-temperature recycling type efficient energy-saving grain drying machine which comprises an air inlet channel, an air outlet channel, a rotational flow filtering mechanism and an adsorption filtering mechanism. The air inlet channel is connected with an air inlet system; the air outlet channel is connected with an exhaust system; the rotational flow filtering mechanism is arranged in the air outlet channel; the adsorption filtering mechanism is connected with the rotational flow filtering mechanism; water and dust particles in high-temperature waste gas are separated and then directly introduced into the evaporator, the evaporator is heated and then introduced into the heat exchanger to be heated, the filtered and heated gas flows through the outer surface of a channel where the waste gas passes, and redundant heat of the filtered and heated gas is transferred to the waste gas; waste heat recovery is achieved, and the temperature of gas entering the drying tower is controlled to be appropriate; the problems that when dust exists in grains, dried damp and hot waste gas carries the dust to be discharged, and the heat exchange efficiency is gradually reduced when the waste gas carrying the dust is recycled are solved.

The utility model discloses a breathing machine humidifying tank and a breathing machine system, and relates to the field of medical instruments. The breathing machine humidifying tank comprises a tank body, a guide sleeve, a telescopic water bag and an operating rod. The tank main body is provided with a highest water line; the telescopic water bag is located in the tank body and horizontally arranged, the top of the telescopic water bag is higher than the highest water line, the telescopic water bag comprises a telescopic sleeve and a hard end plate, one end of the telescopic sleeve is connected with the tank body, the hard end plate is connected with the other end of the telescopic sleeve, and a water suction and drainage hole is formed in the hard end plate and lower than the highest water line. The guide sleeve and the telescopic water bag are arranged in the same direction, and the guide sleeve is connected with the tank body and corresponds to the telescopic water bag in position. And the operating rod penetrates through the guide sleeve, is matched with the guide sleeve and is sealed with the guide sleeve, and the operating rod is connected with the hard end plate. The breathing machine humidifying tank is installed on the breathing machine main machine, and a temperature and humidity sensor and a push-pull structure are arranged in a matched mode to obtain the breathing machine system. According to the utility model, the temperature and humidity of the humidified air at the patient end can be optimal.
