Description

Duckbill type hood Technical Field The utility model relates to the technical field of exhaust devices, in particular to a duckbill type hood. Background Along with the acceleration of the global building industry to zero carbon transformation progress and the increasingly perfect environmental protection regulation system, the requirements of the building field on energy conservation and emission reduction are more and more strict, in a ventilation system, a hood serves as a key component to become a key infrastructure for promoting sustainable development, and the sustainable development of the whole building industry is also affected deeply while the energy conservation and emission reduction of a power-assisted building are carried out. The blast cap is generally made of high-temperature resistant and wear-resistant metal materials, and is required to bear high-temperature and high-speed airflow and scouring of material particles when the vibrating fluidized bed operates, the blast cap is integrally cylindrical, simple in structure and easy to process and manufacture, airflow is vertically conveyed upwards from the bottom, and the side surface of the blast cap is provided with an air inlet hole, so that the airflow is beneficial to diffusing to the vibrating fluidized bed. For the related art, the different wind speeds can cause different speeds of the air flows entering the fluidized bed, when the air flow speeds are too high, particles in the fluidized bed can be subjected to strong disturbance, so that the fluidization state is unstable, but the conduction speed of the blast cap on the air flow is the same, and the blast cap cannot be flexibly applied to the air flows with different speeds, so that the flexibility of the blast cap is poor. Disclosure of utility model In order to improve the flexibility of airflow diffusion of the hood, the application provides a duckbill hood. The application provides a duckbill type hood, which adopts the following technical scheme: The utility model provides a duckbilled formula hood, including hood body and fluid bed, the fluid bed is seted up flutedly, the recess department is equipped with the air distribution board, a plurality of bleeder vents have been seted up on the air distribution board surface, the hood body includes upper shroud and lower shroud, lower shroud is located the air distribution board upper end, upper shroud is located lower shroud upper end, be equipped with the go-between shroud and the lower shroud, the go-between links up upper shroud and lower shroud together, can dismantle between hood body and the air distribution board and be connected, be equipped with a plurality of fixed blocks in the hood body, a plurality of fixed blocks set firmly respectively in the both ends of lower shroud, the fixed block cavity sets up, the one end that the fixed block kept away from the lower shroud is equipped with the lifter, the lifter is inserted and is located in the fixed block, and lifter upper end and upper shroud fixed connection, be equipped with two dwang in the hood, the slide bar both ends are all fixed with slide bar sliding connection along horizontal, the lifter lower tip is equipped with the rotating piece that drives two dwang simultaneous rotation. Through adopting above-mentioned technical scheme, go up shroud and lower shroud cooperation and make the air current blow out the back evenly spread to the air distribution board, the go-between makes the hood body be in relative sealedly, reduce the probability that solid particle piled up in hood department, start the rotation piece, the rotation piece drives the dwang and rotates, the dwang rotates and drives the slide bar and rotate, the slide bar rotates and promotes the lifter lift, the lifter lift drives the upper shroud and goes up and down, thereby change the height of hood body, when meetting the circumstances that the air current velocity of flow changes, make the air current through the velocity of flow of air distribution board relatively stable through adjusting the hood height, the flexibility that the improvement hood used. Optionally, the connecting ring includes upper ring, lower ring and elastic component, and lower ring sets firmly in lower shroud upper end, and upper ring sets firmly in upper shroud lower end, and the upper ring inserts and locates in the lower ring, and upper ring is along vertical and lower ring sliding connection, and the elastic component sets firmly between upper ring and the lower ring. Through adopting above-mentioned technical scheme, go up the ring and follow vertical and lower ring sliding connection, when making last shroud and lower shroud highly change, the go-between link links together last shroud and lower shroud all the time, improves the stability that the hood used. Optionally, the rotating member includes a rotating handle, a first gear and a second gear, the first gear and the second gear are respectively fixed at one ends of the two
