The application discloses a double-fan-leaf suction-discharge structure of a centrifugal fan, and belongs to the technical field of centrifugal fans. The double-fan-leaf suction-discharge structure comprises an impeller, a volute, an air inlet, an air outlet, a motor, a connecting shaft, a bearing and a flow guide channel. The impeller is designed in a double-fan-leaf mode and comprises centrifugal blades and axial-flow blades. The impeller is located in the interior of the volute, and the interior of the volute is further provided with the flow guide channel. The application has novel design and ingenious device. The double-fan-leaf suction-discharge structure is arranged in the interior of the impeller shell and comprises centrifugal blades and axial-flow blades. The external gas is guided to enter the gap between the centrifugal blades in an orderly manner, the axial air suction capacity is improved, the phenomenon that the air pushed by the centrifugal blades overflows along the axial direction is inhibited, and thus the generation of backflow is reduced. The flow guide channel is arranged, the main channel changes from narrow to wide from the air inlet to the air outlet, the entering gas can be stably transported from the air inlet to the air outlet under the action of the main channel, the gas discharge efficiency is improved, and the discharge capacity is increased.

This utility model discloses a photovoltaic module water drainage and sewage discharge device capable of continuous flow guidance and convergence. It includes a top cover plate and a vertical plate. The upper end of the vertical plate is perpendicularly connected to one end of the top cover plate, and the vertical plate is located on one side of the top cover plate. The top cover plate has two downwardly recessed portions extending outward to the outer end of the top cover plate. The outer end of the top cover plate is arc-shaped and inclined downwards. The top cover plate has multiple openings. The lower end of the vertical plate has a laterally extending bottom retaining plate located below the top cover plate. The vertical plate has two elongated holes extending vertically. This photovoltaic module water drainage and sewage discharge device can quickly drain accumulated dust and water from the surface of the photovoltaic module, thereby improving the cleanliness of the photovoltaic module surface.

This utility model relates to the field of adhesive processing technology and discloses a corrugated paper adhesive processing device, including a processing tank. A feed pipe is fixedly installed on the upper part of one side of the inner wall of the processing tank. A drive pipe is vertically rotatably connected inside the processing tank. An agitator is fixedly installed at the lower end of the drive pipe. Air outlets are equidistantly opened on the outer side of the agitator. This utility model controls the operation of an air pump. Through the combination of the air outlet, air vent, and air port, airflow can be introduced into the drive pipe and discharged through the air outlets on the outer side of the agitator. This can agitate the raw materials in the processing tank, further improving the uniform mixing efficiency of the raw materials. When it is necessary to discharge the adhesive from the processing tank, the air vent is closed by a first solenoid valve, and the discharge pipe is opened by a second solenoid valve. The air pump continues to operate. As the air pressure inside the processing tank increases, the discharge speed of the adhesive can be increased, avoiding the adhesive from becoming viscous and resulting in low discharge efficiency.

The utility model relates to agitating unit technical field, and disclose a kind of moment glue sealing agitating unit, including base, agitating box and the stirring rod rotating in agitating box inside, the both sides of agitating box inner wall are rotatably connected with spring rotating shaft, and vertical rod is connected between two spring rotating shafts, limiting component for fixing vertical rod is provided on spring rotating shaft, the lower end of vertical rod is fixedly connected with connecting block, the bottom of connecting block is fixedly connected with rubber shovel plate, and the lower end of stirring rod is provided with driving assembly;This kind of moment glue sealing agitating unit, after using the device to complete the moment glue stirring, can be discharged into base by pipe body and collected, the moment glue in the inside of base is in the process of discharging, vertical rod can be made to swing automatically by driving assembly, so that rubber shovel plate swings in the inside of base, and then accelerates the discharging speed of moment glue, so that staff manually swings vertical rod to make rubber shovel plate swing is not needed, so that it is more convenient when accelerating the discharging speed of moment glue in the inside of base.

This utility model relates to the technical field of PVC pipe processing equipment, and in particular to a device for simultaneous cooling and shaping of the inner and outer walls of multi-layer composite PVC pipes. The technical solution includes a mounting base and a production device. The mounting base is equipped with multiple conveying rollers for transporting the pipe material, and a fixing cover for installation is provided on the top of the mounting base. A sizing sleeve for shaping is provided on one side of the production device. This utility model, through the arrangement of an air collection pipe, an air pump, a second air guide hose, and a first air guide hose, can achieve air cooling of the pipe material, promoting rapid evaporation of residual moisture on the pipe surface and further reducing the temperature. Combined with water cooling via the sizing sleeve, it can effectively improve the problem of uneven cooling speed caused by uneven water flow distribution when using single water cooling. Furthermore, through the arrangement of threaded rods, connecting sleeves, and connectors, the diameter of the circle formed by multiple connecting sleeves can be adjusted according to the pipe size, without needing to replace them simultaneously with the sizing sleeve, thus improving the equipment's versatility.
