Description

Circulating fluidized bed hood easy to install Technical Field The utility model relates to the technical field of fluidized bed equipment, in particular to a circulating fluidized bed hood easy to install. Background The circulating fluidized bed boiler is a coal burning technology with high efficiency, low pollution and good comprehensive utilization, and has the unique advantages of coal adaptability, variable load capacity and pollutant emission reduction, so that the circulating fluidized bed boiler is rapidly developed. Among the prior art, the utility model patent of publication number CN218763374U discloses a hood mounting structure for circulating fluidized bed boiler, and it can reduce installation work load, and it is simple to dismantle the change, can not cause the damage to the hood, and it includes the hood takeover of installing on the air distribution board, install the hood head on the hood takeover, its characterized in that, the first through-hole has been seted up on hood takeover, the hood takeover is last to be seted up with first through-hole complex second through-hole, the hood head suit in on the hood takeover and by inserting the round pin axle of first through-hole, second through-hole will the hood head is fixed, hood head lower part outer lane cover is equipped with the ring retaining ring. However, when the conventional circulating fluidized bed hood is used, the hood cannot be correctly placed on the fluidized bed, and manual calibration is required for a worker. In view of this, we propose a circulating fluidized bed hood that is easy to install. Disclosure of utility model The utility model aims to provide a circulating fluidized bed hood which is easy to install so as to solve the problem of hood calibration in the prior art. In order to achieve the above purpose, the technical scheme adopted by the utility model is as follows: The utility model provides an easy circulating fluidized bed hood of installation, includes the mount pad, the inner wall of mount pad runs through there is the mount tube, the top fixedly connected with inner hood of mount tube, the inner through-hole has been seted up to the outer wall of inner hood, the outside of inner hood has cup jointed outer hood, outer through-hole has been seted up to outer hood outer wall, the outer wall fixedly connected with installing frame of mount tube, the inside of installing frame is provided with the screw rod, the outer wall threaded connection of screw rod has the expansion bracket, the equal fixedly connected with work orifice plate in both ends of expansion bracket, the inslot swing joint of work orifice plate has the spliced pole, the inner wall of spliced pole runs through there is the gag lever post, the embedded plate of outer wall fixedly connected with of gag lever post and mount tube outer wall fixed connection, the embedded groove has been seted up to the junction of mount pad, the mounting groove has been seted up with the junction of installing block to the embedded groove. Preferably, the central axis of the inner hood is perpendicular to the central axis of the inner through hole. Preferably, the embedded plates are provided with two groups, and the two groups of embedded plates are symmetrical with respect to the central axis of the installation tube. Preferably, the mounting tube forms a positioning structure with the mounting seat through the embedded plate and the embedded groove. Preferably, the hole groove of the working hole plate is inclined. Preferably, the connecting column forms a sliding structure between the working pore plate and the limiting rod.
