This utility model relates to the field of exhaust structures, specifically an exhaust mechanism for a heating boiler, comprising: an air guide pipe and a water guide pipe, the ends of which are close to the boiler and connected to the surface of the boiler; an exhaust device installed at the end of the air guide pipe away from the boiler, the surface of which is connected to the end of the water guide pipe; wherein, the exhaust device includes a filter assembly fixedly connected to the end of the air guide pipe, and a servo motor is fixedly connected to the surface of the filter assembly; the device preheats the liquid inside the preheating chamber by passing high-temperature gas through a second vent pipe and multiple first vent pipes. Because the first vent pipe is spirally shaped to extend the flow path of the high-temperature gas, the gas heat exchange time is extended, and the spiral plate increases the contact area for heat exchange, thus preheating the water inside the boiler body, avoiding the waste of some of the heat energy generated inside the boiler body, and improving the energy efficiency of the device.

The utility model discloses a kind of fire powder weight counting devices for spitting bead type firework production, including support plate, fire powder tank is provided in the upper portion of support plate, collecting box is installed in the bottom of fire powder tank, support frame is fixed in the side of support plate, and the support frame supports and positions collecting box, the top of fire powder tank is provided with the air pressure adjusting assembly being communicated with its inner cavity, the upper portion of the side of fire powder tank is provided with the feeding assembly being communicated with its inner cavity.The fire powder weight counting device for spitting bead type firework production, fire powder weighing process is in sealed environment, reduce the amount of fire powder floating to outside, reduce the hidden danger of production safety while avoiding fire powder waste, the device is fed and discharged by adjusting the air pressure in fire powder tank to control fire powder, convenient for the replenishment of fire powder in fire powder tank, while avoiding fire powder to be jammed in discharging assembly by static friction, ensure that fire powder is effectively discharged and weighed, facilitate the production preparation of fireworks.

This invention relates to the field of agricultural irrigation, specifically to an integrated water and fertilizer irrigation device for fruit and vegetable cultivation. It includes a base plate, a frame, a controller, a feeding mechanism, a water conveying mechanism, an adjusting mechanism, and two sets of sprinkler irrigation mechanisms. The frame is fixedly mounted on the base plate. The feeding mechanism includes a storage bin, a feeding assembly, a conveying assembly, and a crushing assembly. The water conveying mechanism includes a mounting frame, a mixing bin, a level sensor, a water supply assembly, and a stirring assembly. The adjusting mechanism includes a sliding assembly and a water supply assembly. Each set of sprinkler irrigation mechanisms includes a swing assembly and an adjustable spray assembly. The swing assembly is fixedly mounted on a corresponding sliding assembly, and the adjustable spray assembly is fixedly mounted at the bottom of the swing assembly. This invention allows for integrated water and fertilizer irrigation of fruits and vegetables by pre-filling fertilizer into the feeding hopper and operating the controller to open two manual valves at appropriate times. It is convenient, fast, safe, and efficient, greatly improving the fertilization efficiency for fruits and vegetables.
