Conveying device used for conveying bagasse to boiler

[0034] Example 1

[0035] See Figure 1 to Figure 3 As shown, a conveying device for conveying bagasse to a boiler according to the present invention includes a base frame 1, a support base 2 and an impeller 3 mounted on the base frame 1, and a drive motor 4 mounted on the support base 2. And the tripod 5, the shaft body 6 rotatably connected to the support base 2. In this embodiment, the outer side of the shaft body 6 is sleeved with two rolling bearings spaced apart from each other, the two rolling bearings are mounted on the support base 2, and the tripod 5 is at a right angle Triangular, one right-angled side of the tripod 5 is installed on the support base 2, and the other right-angled side of the tripod 5 is installed on the impeller 3. Using the principle of stability of the triangle, the impeller 3 is stably positioned on the base 1 and the support The seat 2 prevents the impeller 3 from shaking during operation; the driving motor 4 drives the impeller 3 to rotate through th

[0045] In this embodiment, the shell 9 is a metal alloy shell, and the metal alloy material for the shell consists of the following components by weight percentage: Cr 16%, Ni 8%, Si 2%, Mn 0.6%, Ti 0.02%, Sc 0.03 %, Ce0.1%, Nb 0.02%, Mo0.02%, Cu 0.25%, P 0.02%, S 0.01%, N 0.12%, C 0.04%, and the balance is Fe.

[0046] Preferably, the method for preparing the metal alloy material for the shell includes the following steps:

[0047] (1) Add other components except Sc and Ce according to the above ratio, and smelt in a vacuum induction electric furnace. After all the components are melted, add 0.08% of the alloy melt weight as a deoxidizer Ca to deoxidize the alloy melt. ; After deoxidation, add Sc and Ce alloy melt and stir continuously for 3min; after standing for 2min, pour the alloy melt into the casting mold to form an ingot. The casting temperature is 1500℃. After the mold cools, The alloy ingot is released;

[0053] In this embodiment, the shell 9 is a metal alloy shell, and the metal alloy material for the shell consists of the following components by weight percentage: Cr 18%, Ni 5%, Si 3%, Mn 0.2%, Ti-0.04%, Sc 0.06%, Ce0.05%, Nb 0.04%, Mo 0.01%, Cu 0.35%, P 0.01%, S 0.02%, N 0.08-0.12%, C 0.00.07%, and the balance is Fe.

[0054] Preferably, the method for preparing the metal alloy material for the shell includes the following steps:

[0055] (1) Add other components except Sc and Ce according to the above proportion, and smelt in a vacuum induction electric furnace. After all the components are melted, add 0.15% of the alloy melt weight as a deoxidizer Ca to deoxidize the alloy melt. ; After deoxidation, add the Sc and Ce alloy melt and stir continuously for 5 min; after standing for 4 min, pour the alloy melt into the casting mold to form an ingot. The casting temperature is 1600 ℃. The alloy ingot is released;
