DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] like Figure 1-5 As shown, this embodiment proposes a saltpeter evaporation tank for a saltpeter workshop in a salt field, comprising a tank body 10, on which a liquid inlet pipe 11 is provided;

[0027] The tank body 10 is provided with a connecting pipe mouth 14, and a sealing cover 20 is provided at the connecting pipe mouth 14. The sealing cover 20 is provided with a movable rod 30, and a stirring blade 40 is rotatably provided on the movable rod 30. The stirring blade 40 is arranged at the position of the liquid inlet pipe 11. The liquid inlet pipe 11 guides the fluid to the surface of the stirring blade 40, driving the stirring blade 40 to rotate in the inner cavity of the tank body 10.

[0028] In the present embodiment, when the solution is used to make nitrate in the nitrate making workshop, the solution is introduced into the tank body 10 from the liquid inlet pipe 11. When the solution is introduced into the tank body 10, the flowing fluid impacts the stirring blade 40, driving the stirring blade 40 to rotate, thereby stirring the solution in the tank body 10. The rotating flow breaks the boundary layer of the fluid, increases the turbulence and eddy current inside the fluid, enhances the heat transfer efficiency inside the fluid, improves the efficiency of heat exchange, and facilitates evaporation. Moreover, the rotating flow makes the liquid surface constantly renewed and continuously contacts the gas phase, which can accelerate the evaporation rate of the liquid and improve the evaporation efficiency. Of course, the rotating flow can reduce dead corners, inhibit the formation of scale layers, and reduce the accumulation of dirt on the inner wall of the equipment.

[0029] Specifically, the stirring blade 40 is provided with a connecting sleeve 41, and a one-way bearing 42 is provided in the connecting sleeve 41;

[0030] The inner wall of the connecting sleeve 41 is connected to the outer ring of the one-way bearing 42 , and the inner ring of the one-way bearing 42 is connected to the outer wall of the movable rod 30 .

[0033] In this embodiment, when the fluid enters the tank body 10 through the tapered portion 12, the area through which the fluid flows through the pipeline becomes smaller. In order to maintain a constant flow rate, the flow velocity of the fluid increases, thereby facilitating driving the stirring blade 40 to rotate.

[0034] Specifically, the outer wall of the movable rod 30 is provided with a rotating blade 32, and the rotating blade 32 is fixedly connected to the movable rod 30;

[0035] The movable rod 30 is rotatably connected to the sealing cover 20 .

[0036] In this embodiment, when the stirring efficiency needs to be improved, the movable rod 30 is driven to rotate through an external power device, and of course the rotation direction is rotated toward the direction in which the one-way bearing 42 is locked, thereby driving the stirring blade 40 and the rotating blade 32 to rotate simultaneously, thereby improving the stirring efficiency.

[0037] Specifically, the tank body 10 is provided with a heating chamber 13 , and the rotating blades 32 are arranged at the heating chamber 13 .

[0038] In this embodiment, when the rotating blades 32 are arranged at the heating chamber 13, the efficiency of heat exchange can be improved.

[0039] Specifically, a wheel disc 31 is disposed on the movable rod 30 , and the wheel disc 31 is fixedly connected to the movable rod 30 .

[0040] In this embodiment, the wheel disc 31 is provided to facilitate the connection of the power device with the wheel disc 31 through a belt, so as to facilitate driving the movable rod 30 to rotate;

[0041] Of course, the driving device includes but is not limited to a servo motor.

[0042] Specifically, the sealing cover 20 is provided with an air outlet pipe 21, and the sealing cover 20 is provided with a guide slope 22;

[0043] The gas outlet pipe 21 is disposed on the side of the guiding slope 22 , and the guiding slope 22 guides the gas to flow toward the gas outlet pipe 21 .

[0044] In this embodiment, the guide slope 22 can be provided to facilitate the steam to enter the gas outlet pipe 21 and discharge the steam.
