Embodiment 1

[0039] Embodiment 1, reference figure 1 , high-temperature and high-corrosion material suction and discharge machine, including a casing in the form of a volute, an air inlet 2 on the front side of the casing, an air inlet outlet 3 on the front side of the casing, a backflow fan impeller 4 (made of ordinary iron plate), blades 5, Blisk 6, air inlet 7 on the front side of the impeller (negative pressure clearance of the impeller), disc isolation splitter 8 on the front side of the impeller (made of manganese steel plate, the outlet surface is uneven), air inlet 10 on the rear side of the impeller, and air inlet on the rear side of the casing Tuyere 11, casing axial rear impeller working room 12, casing axial front material suction and discharge chamber 13, impeller working room radial side wall 14 is provided with impeller working room air outlet 15 (outlet direction turned left 90° , i.e. upward), the radial sidewall of the material suction and discharge chamber is provided wi...

Embodiment 2

[0043] Embodiment 2, refer to figure 2 , image 3 , this example is basically the same as Example 1, the difference is that the isolation shunt 8 of this example adopts a double-layer clamping wall structure, which is composed of the inner clamping wall 17 of the isolation divider and the outer clamping wall 18 of the isolation divider, and the isolation shunt Between the inner clamping wall 17 of the device and the outer clamping wall 18 of the isolation shunt, an isolating splitter clamping wall flow channel 19 is provided, and an isolating splitter clamping wall flow channel air inlet is provided on the isolation splitter outer clamping wall 18 on the bottom surface of the isolating splitter 20. The air inlet 20 of the wall flow channel of the isolation splitter is connected with the air inlet 10 on the rear side of the impeller. The outer wall 18 of the isolation splitter on the side of the isolation splitter is provided with an air outlet 21 of the wall flow channel of t...

Embodiment 3

[0049] Embodiment 3, refer to Figure 4 , Figure 5 , this example is basically the same as Example 2, the difference is that this example uses film cooling technology to cool the isolation shunt. The isolation splitter of this example is also a double-layer wall structure, and the outer wall of the isolation splitter bottom surface of the isolation splitter is also provided with an air inlet 20 (outside the isolation splitter) that is connected to the air inlet of the rear side of the impeller. There is no air outlet 21) on the sandwich wall of the isolation splitter, and the inner wall of the isolation splitter of the isolation splitter is provided with fine air holes 22 in the inner sandwich wall of the isolation splitter. This example sucks and discharges high-temperature and highly corrosive chemical gas materials.

[0050] When working, the cold air sucked into the flow channel of the wall of the isolation splitter through the air inlet on the rear side of the impeller...
