An underground heat storage tank is arranged under the ground surface inside a greenhouse drying room; a solar-air heat collector is arranged at the upper part outside the greenhouse drying room; an automatic controller, a blower, a hot wind discharge pipe, a hot wind delivery pipe and a cold air returning pipe are arranged in the greenhouse drying room; two ends of the hot wind delivery pipe with a suction fan and a third valve are respectively communicated with the solar-air heat collector and the underground heat storage tank; two ends of the cold air returning pipe with a first valve are respectively connected on the solar-air heat collector and the underground heat storage tank; two ends of the hot wind discharge pipe with a second valve are respectively communicated with the hot wind delivery pipe and the cold air returning pipe; an exhaust outlet is arranged on the wall of the greenhouse drying room; and the automatic controller is connected with the suction fan, the blower, the first valve, the second valve and the third valve respectively by leads. The greenhouse heat-storage type solar hot-wind drying device fully utilizes solar energy as drying energy and has the characteristics of being simple in structure, low in operation cost and excellent in environment-friendly effect.

The invention discloses a ventilation and cooling device for a digital generator set, which comprises an engine side cover, a muffler arranged outside the engine side cover, a crankshaft with one end protruding from the engine side cover, and a crankshaft installed on the crankshaft and located between the engine side cover and the muffler. The impeller is characterized in that a volute air guide device is also provided between the engine side cover and the muffler, and the volute air guide device is provided with a main air inlet and outlet along the axial direction of the crankshaft. The inside of the wind device has a volute-shaped inner cavity, and the impeller is located in the volute-shaped inner cavity. In the present invention, a volute type air guiding device is added between the engine side cover and the muffler. After the volute type air guiding device is combined with the impeller inside, it is equivalent to jointly forming a "turbocharged cooling device". The "supercharging cooling device" can eliminate the phenomenon of hot air circulation inside the digital generator set and enhance the cooling effect.

The invention discloses a food grinder. A cutter holder system of the grinder comprises a cutter holder and a cutter shaft, wherein the cutter holder is provided with a bearing; the lower end of the cutter shaft is arranged in the bearing, and the upper end of the cutter shaft is provided with a grinding component; a cup body is provided with a material inlet communicated with the outside; a filtering device is sleeved below the grinding component on the cutter shaft; a powder discharging / heat radiating device is sleeved below the filtering device; a powder discharging / heat radiating device is sleeved above the bearing on the cutter shaft; and a position on the side wall of the cutter holder, which corresponds to the powder discharging / heat radiating device, is provided with an outlet communicated with the outside. Food is delivered to the cup body from the material inlet and ground by the grinding component; the grinding degree is controlled by the filtering device; and the ground food is discharged from the food outlet by the powder discharging / heat radiating device. A convective air cooling system is formed on a passage in a whole food treating process so as to rapidly carry heat produced by high-speed friction between the cutter shaft and an oil-containing bearing out of the cup body and realize automatic food treatment started from feeding. The grinder can run continuously without causing thermal protection and powder burning and the service life of the grinder is prolonged.

The invention discloses a battery acid adding and forming system, comprising: a battery vacuum box, an acid kettle vacuum box, an acid kettle arranged in the acid kettle vacuum box, a quantitative acid adding system, and a mounting plate. The accumulator acid addition and chemical formation system of the present invention is divided into three layers, the bottom layer is the battery vacuum box for storing the battery, the middle layer is the acid pot vacuum box for the acid pot, and the upper layer is the part of the quantitative acid addition system The structure separates the battery from the acid pot and sets them on two separate floors. There is no acid mist in the battery vacuum box, which avoids corrosion problems such as battery terminals and connections, and keeps the battery dry. It can realize the synchronous acid addition of the storage battery, and keep the resting time of ionization after acid addition consistent; it can also realize the vacuum formation process.

The invention relates to a method for commissioning an adsorbent bed in an acetone recycling process, which comprises the following steps: 1) carrying out commissioning resolution on an adsorbent bed, introducing steam at a flow rate of 7-9 tons / hour for 1-1.5 hours; 2) after the commissioning resolution is completed, introducing acetone / air mixed gas into a secondary cooler through a primary cooler, and enabling the temperature of the acetone / air mixed gas at the outlet of the secondary cooler to be 42-44 DEG C; and 3) after the adsorption of activated carbon is completed, carrying out resolution, and introducing steam into the adsorbent bed at a flow rate of 12 tons / hour for 11-16 minutes to resolve acetone; when the acetone content of tail gas is lower than 45PPM, gradually reducing the flow rate of the steam until the corresponding acetone content of the tail gas is 40-45PPM; and recovering a normal operation level. The method provided by the invention can improve the acetone adsorption capability of the activated carbon, reduce the acetone content in the tail gas and reduce the emission of acetone.
