Fig. 7 is a schematic view of the structure of the blowing hood of the present application. FIG. 8 is a schematic view of the upper seal assembly of the present application. Fig. 9 is a schematic view of the structure of the front inspection cover of the present application. Fig. 10 is a schematic view of the structure of the post-inspection cover of the present application. Referring to fig. 1 to 10, the blowing main body includes a blowing hood 2, a front inspection cover 3, a rear inspection cover 4, and a cover plate 5, and the blowing hood 2, the front inspection cover 3, the rear inspection cover 4, and the cover plate 5 are located outside the blowing main body and are used for protecting the device inside the blowing main body.
Specifically, the blowing guard 2 is arranged around the blowing assembly 1, so that the blowing assembly 1 is protected, and the impact of the blown sorting objects can be buffered.
The blowing hood 2 is composed of a bottom hood 19, an upper hood 20 and an upper sealing assembly 21. The bottom cover 19, the upper cover 20 and the upper sealing assembly 21 are connected, so that the blowing assembly 1 can be sealed and protected.
The upper sealing assembly 21 is composed of a sealing rubber cushion 22 and a first pressing plate 23, wherein the sealing rubber cushion 22 is positioned at the bottom of the first pressing plate 23 and is connected with the upper cover 20, so that the sealing performance of the blowing device can be ensured, and dust is prevented from entering the cover from the upper cover.
In an alternative embodiment of the present invention, the length of the upper sealing assembly 21 may cover the top of the upper cover 20 and the connection between the top and the side of the upper cover 20, so that the sealing performance of the blowing device may be better ensured by the upper sealing assembly 21.

At the time of inspection, the blowing main body is hoisted through the hanging hole 24 of the front inspection cover 3, and then the rear inspection cover 4 is opened through the mounting clamping plate 27 of the rear inspection cover 4 for inspecting the blowing main body.
The working state of the dry separator is the blowing work. When the dry separator starts to perform blowing action, the pressure sensor 10 outputs a data signal corresponding to the change to be compared with a preset data signal (the preset signal is a standard value obtained by testing measured data before delivery), and when the blowing data signal is different from the preset data signal, the dry separator judges that the output is abnormal, namely the blowing nozzle aperture 40 of the blowing nozzle 14 is blocked, so that the effect of monitoring the blowing nozzle aperture in real time is achieved.
When the dry separator is in operation, the non-actuated blowing nozzle is monitored for a long time, and the air blowing ash discharge can be carried out according to the material conveying rule (namely, the intermittent operation is carried out when the material passes), so that the air blowing action is carried out when no material passes, and the aperture 40 of the blowing nozzle is kept smooth. The blowing anti-blocking structure (namely, the bypass air inlet cover 9 continuously enters air, and air enters the inner cavity 33 of the blowing plate) forms positive pressure through continuous air inlet, so that dust is prevented from entering.
The effect of real-time monitoring is realized by the change of the output signal of the pressure sensor 10 during the blowing action. The condition of blowing blockage is reduced by an air blowing ash discharging mode. The intelligent and reliable spray nozzle has the advantages of being strong in operability, visual and reliable in feedback, compact in overall structure, safe, reliable, convenient to position and install, intelligent, efficient, capable of conducting real-time monitoring and protection, greatly reducing the blocking condition of the spray nozzle, and improving the effect of spray and separation.
