The utility model discloses a spraying system of a spraying tower, which relates to the waste gas treatment technology, and adopts the technical scheme that the spraying system comprises a tower body, a spraying pipe and a nozzle, the spraying pipe comprises a main pipe and a branch pipe, the nozzle is rotatably connected to the branch pipe, a rotating piece is arranged in the nozzle, and the nozzle is provided with an atomizing opening and a liquid flow opening. The spray head starts to rotate under the action of the rotating part, the treatment liquid in the spray head is sprayed out from the atomization opening and the liquid flow opening under the action of liquid pressure, the treatment liquid sprayed out from the liquid flow opening is large in particle diameter and can effectively combine pollutants with large diameters in waste gas, the treatment liquid sprayed out from the atomization opening is small in particle diameter, and the pollutants can be effectively combined with the pollutants with large diameters in the waste gas. The spray tower is simple in structure, large in dispersion area and longer in hang time, and can be fully combined with pollutants with smaller diameters in waste gas, and meanwhile, as the rotation of the spray head can provide centrifugal force for the treatment liquid leaving the spray head, the treatment liquid sprayed out of the atomization port and the liquid flow port can have wider coverage area, and the working efficiency of the spray tower is improved.

This invention provides a laminating machine for composite paperboard and its working method, relating to the field of paperboard processing technology. The machine includes a frame with a waterproof paper layer conveying station and a paperboard conveying station along the vertical direction. The waterproof paper layer conveying station includes a waterproof paper layer servo conveyor belt and a waterproof paper layer guide frame. A gluing and pressing station is provided along the horizontal direction of the frame. The gluing and pressing station includes a pre-pressing flat roller group, a pressing roller group, a gluing structure, and a linkage mechanism. The linkage mechanism is installed at both ends of the upper pre-pressing flat roller. The gluing structure is located on the frame and is connected to the linkage mechanism, performing lifting and lowering actions relative to the rotating upper pre-pressing flat roller. The gluing structure stores glue internally, and a glue outlet is formed on its downward-facing side. The pressing roller group is located on one side of the waterproof paper layer guide frame. Through the working method, this invention obtains a paperboard with a waterproof paper layer laminated to its surface. When applied in packaging, transportation, and other scenarios, it can provide waterproofing, moisture resistance, and increased paperboard strength.

The utility model discloses a snack stirring and powder scattering device which comprises a stirring barrel and a mixing barrel which are arranged in an up-and-down butt joint mode, a discharging plate is further arranged between the stirring barrel and the mixing barrel, the discharging plate is of a cylindrical cavity structure, the interior of the cylindrical cavity structure is hollow, and a plurality of discharging holes are correspondingly formed in the upper end face and the lower end face of the cylindrical cavity structure. Rotatable discharging devices which are arranged in a cavity of the discharging plate are arranged among the discharging holes which are correspondingly formed up and down, a transmission shaft which is arranged among the stirring barrel, the discharging plate and the mixing barrel in a penetrating mode from top to bottom is vertically arranged in the middle of the discharging plate, and a stirring device is arranged on the transmission shaft; the transmission gear in transmission connection with the discharging device is arranged on the section, arranged in the discharging plate, of the transmission shaft, so that the seasoning scattering area is larger, seasoning scattering is more uniform, and the working efficiency is improved.

This invention relates to the field of wastewater treatment technology and discloses a high-efficiency filtration treatment device for industrial wastewater, including a lower filter tank. An upper filter tank is connected to the upper surface of the lower filter tank via a flange. A limiting cylinder is fixedly connected to the upper surface of the upper filter tank. A mounting base is sleeved on the inner surface of the limiting cylinder. A U-shaped electric heating tube is fixedly connected to the lower surface of the mounting base. In this invention, the U-shaped electric heating tube can heat the wastewater to promote pollutant decomposition and separate oily substances. During the heating process, a temperature monitoring gauge can monitor the internal temperature of the lower and upper filter tanks in real time, facilitating precise temperature control and gradient heating to improve pollutant decomposition efficiency. A stirring paddle agitates the wastewater, promoting its flowability and improving the uniformity of heating, thus enhancing the pollutant decomposition effect.
