The invention relates to an air controlling device used for gathering air and generating electricity. The air controlling device used for gathering the air and generating the electricity is characterized in that the air controlling device used for gathering the air and generating the electricity comprises a cylinder body, an air inlet and an air outlet are respectively arranged at the two ends of the cylinder body, an opening is formed in the approximately middle portion of one side wall of the cylinder body, transverse sliding grooves are both formed in corresponding positions of the inner side faces of the cylinder walls on two sides of one side, close to the air outlet, of the opening, a sliding plate is arranged between the two transverse sliding grooves and is connected with a driving mechanism. Rotary sliding blocks are both arranged on two edges of one edge close to the air inlet, of the opening, and a wind board is arranged between the two rotary sliding blocks. The inner side of the wind board and the inner side of the sliding plate are hinged together, a connecting plate is arranged on the inner side of the wind board, one side of the connecting plate is hinged on the cylinder wall between the air inlet and the opening, and the side, opposite to the hinged side, of the connecting plate is arranged on the inner side face of the wind board in a free mode. By the adoption of the air controlling device used for gathering the air and generating the electricity, the use ratio of wind energy can be greatly improved, and the air controlling device used for gathering the air and generating the electricity is suitable for adjusting air quantity of the air inlet of a wind driven generator.

The invention provides a multi-row synthetic tow cooling device. The multi-row synthetic tow cooling device comprises a cooling box and an air supply device used for supplying cold air into the cooling box. A plurality of rows of air duct assemblies for tows to pass through are arranged on the cooling box, a perforated plate is arranged between the cooling box and the air supply device, and a plurality of vent holes are formed in the perforated plate. Cold air from the air supply device enters the exteriors of silk screen cylinders in the air duct assemblies through the vent holes and enters the interiors of the silk screen cylinders through the outer circumferences of the silk screen cylinders. Circulation space is formed in the outer circumferences of the silk screen cylinders, and the adjacent silk screen cylinders in the same row, the adjacent silk screen cylinders in different rows and different inner walls of the cooling box are communicated through the circulation space. By controlling the amount of the cold air entering different positions in the circulation space, the differential values between air pressures of the cold air at different positions in the circulation space and air pressures inside the silk screen cylinders are basically consistent.

The invention provides a multi-row synthetic tow cooling device, which includes a cooling box, a perforated plate and a housing connected under the perforated plate. Multiple rows of wire mesh cylinders are arranged on the cooling box for the tow to pass through. A perforated plate is set between the air devices, and several ventilation holes are set on the perforated plate. The cold air from the air supply device enters the outside of the wire mesh cylinder through the ventilation holes, and enters the wire mesh cylinder through the outer circumference of the wire mesh cylinder. Inside, the fine flow of polymer melt that enters the inside of the screen cylinder and is sprayed out by the spinneret is cooled into filaments, and a circulation space is formed on the outer circumference of the screen cylinder, and the circulation space communicates with adjacent screens in the same row cylinder, different rows of adjacent wire mesh cylinders, and different inner walls of the cooling box, by controlling the amount of cold air entering different positions in the circulation space, the wind pressure of the cold air at different positions in the circulation space is the same as that inside the wire mesh cylinder The difference in wind pressure is basically the same.

To solve the problems that when cooling devices in the prior art are used, powder in materials leaks to cause air pollution and air coolers consume energy, the invention provides a cooling device for an annular cooling machine. The cooling device comprises one or more sealed air suction chambers which are arranged outside an outer cylinder body, each sealed air suction chamber comprises a side wall, an upper cover and a lower cover, all ventilation holes or the ventilation holes in the lower portion of the outer cylinder body are covered with annular sealed spaces formed by the upper covers, the lower covers, the side walls and the outer cylinder body, the side wall of each sealed air suction chamber is provided with one or more air suction openings, and the air suction openings are used for being communicated with a suction fan in a sealed mode. The whole or part of the cooling device uses air as a cold air source, and energy is saved; meanwhile, the intensity of external pressure of the annular cooling machine is less than the intensity of internal pressure of the annular cooling machine, namely negative pressure operation is conducted, and the problem that the powder in the materials leaks is solved effectively.
