Embodiment 1
[0029]This embodiment provides an all-in-one machine for spraying oxygen-increasing medicines for fish ponds, including a hull 1, the upper end of the hull 1 is sequentially provided with a water suction pump 2, a second water pump 6 and a tank body 5 along its length direction, and the input end of the water suction pump 2 is worn Pass the hull 1 and extend into the water. An aeration plate 3 is arranged above the water suction pump 2. The aeration plate 3 is connected to the output end of the water suction pump 2 through a connecting pipe 4. The input end of the second water pump 6 is connected to the tank body 5. The second water pump The output port of 6 is provided with branch pipe 7, and branch pipe 7 is connected with aeration plate 3, and aeration plate 3 is elliptical, and aeration plate 3 is provided with the first inlet 8 that is connected with connecting pipe 4 and the first inlet 8 that is connected with branch pipe 7. Two inlets 9, the aeration plate 3 is provided...
Embodiment 2
[0039] This embodiment provides an all-in-one machine for sprinkling oxygen-increasing medicines for fish ponds. The structure is exactly the same as that in Embodiment 1, wherein the outer surface of the hull 1 is coated with a corrosion-resistant metal coating, and the composition of the corrosion-resistant metal coating is By mass percentage: C: 0.05%, Mn: 0.18%, Cr: 4.79%, Ni: 0.15%, Cu: 0.25%, Mo: 0.65%, W: 0.15%, V: 0.28%, Al: 0.20%, Ti: 0.15%, B: 0:050%, S: 0.001%, P: 0.002%, the balance is Fe;
[0040] The treatment process of corrosion-resistant metal coating is carried out in the following steps:
[0041] Step 1: Put C, Mn, Cr, Ni, Cu, Mo, W, V, Al, Ti, B, S, P and Fe into the smelting furnace, increase the temperature to 560°C, keep it for 3 hours, and then Increase the temperature to 1480°C, keep it warm for 4 hours, then use air cooling, cool to 534°C at a cooling rate of 17°C / s, and then air cool to room temperature to obtain a metal body;
[0042] Step 2: Put ...
Embodiment 3
[0047] This embodiment provides an all-in-one machine for sprinkling oxygen-increasing medicines for fish ponds. The structure is exactly the same as that in Embodiment 1, wherein the outer surface of the hull 1 is coated with a corrosion-resistant metal coating, and the composition of the corrosion-resistant metal coating is By mass percentage: C: 0.04%, Mn: 0.17%, Cr: 4.78%, Ni: 0.13%, Cu: 0.24%, Mo: 0.63%, W: 0.14%, V: 0.27%, Al: 0.19%, Ti: 0.14%, B: 0030%, S: 0.0008%, P: 0.001%, the balance is Fe;
[0048] The treatment process of corrosion-resistant metal coating is carried out in the following steps:
[0049] Step 1: Put C, Mn, Cr, Ni, Cu, Mo, W, V, Al, Ti, B, S, P and Fe into the smelting furnace, increase the temperature to 558°C, keep it for 2 hours, and then Increase the temperature to 1470°C, keep it warm for 3 hours, then use air cooling to cool to 532°C at a cooling rate of 16°C / s, and then air cool to room temperature to obtain a metal body;
[0050] Step 2: Pu...
