[0026] At present, there are no stirring facilities in storage tanks such as coal chemical ash water tanks, ash water slurry tanks, and wet desulfurization towers, or the stirring facilities are improperly located, resulting in the deposition of materials at the bottom, blocking the material inlet pipeline, and insufficient stirring of the materials at the bottom, resulting in insufficient inlet suction of the material conveying pump, which in severe cases affects the normal conveying of materials and causes material overflow or other accidents. In addition, due to the small volume of some storage tanks, the investment in installing a stirrer is large, and the operation and maintenance costs are high. Instead, a side-through agitator with a hole in the side wall of the storage tank is selected, which is very easy to leak materials at the rotating part.

[0027] In order to solve the above-mentioned problems, the present application proposes a tank stirring device. The embodiments of the present application are further explained below in conjunction with the accompanying drawings.

[0028] Reference Figure 1The present application provides a storage tank stirring device, including a storage tank 100, an annular disturbance pipeline 110, a first material conveying pipeline 210, a second material conveying pipeline 220, a material circulation pipeline 230, a circulating liquid pump 200 and a plurality of sinking injection mechanisms; the annular disturbance pipeline 110 and the plurality of sinking injection mechanisms are all arranged inside the storage tank 100, and the annular disturbance pipeline 110 and the plurality of sinking injection mechanisms are all arranged near the bottom of the storage tank 100, the plurality of sinking injection mechanisms are evenly distributed at the bottom of the annular disturbance pipeline 110, and each sinking injection mechanism is respectively connected to the annular disturbance pipeline 110; one end of the first material conveying pipeline 210 is connected to the input end of the circulating liquid pump 200, the other end of the first material conveying pipeline 210 is penetrated through the side wall of the storage tank 100, and the first material conveying pipeline 210 is close to the bottom of the side wall of the storage tank 100. The first material conveying pipeline 210 is provided with a first end thereof, one end of the second material conveying pipeline 220 is connected to the output end of the circulating liquid pump 200, the material circulation pipeline 230 is communicated with the second material conveying pipeline 220, and the connection between the material circulation pipeline 230 and the second material conveying pipeline 220 is arranged close to the other end of the second material conveying pipeline 220, the diameter of the material circulation pipeline 230 is smaller than the diameter of the first material conveying pipeline 210, and the end of the material circulation pipeline 230 away from the second material conveying pipeline 220 extends into the interior of the first material conveying pipeline 210 and is connected to the annular disturbance pipeline 110; the circulating liquid pump 200 is used to pressurize the material in the storage tank 100, so as to convey the material conveyed to the second material conveying pipeline 220 from the material circulation pipeline 230 to the annular disturbance pipeline 110, and spray it out through a plurality of sinking injection mechanisms connected to the annular disturbance pipeline 110.

[0029] In this embodiment, four downward-sinking injection mechanisms are provided. In other embodiments, other numbers of downward-sinking injection mechanisms may be provided according to the stirring effect required by the storage tank 100, and are not limited to the embodiment of the present application.

[0030] In the present application, the circulating liquid pump 200 is used to pump the material in the storage tank 100 through the first material delivery pipeline 210 to the second material delivery pipeline 220, and deliver it from the second material delivery pipeline 220 to the next process. The circulating liquid pump 200 is also used to pressurize the material in the storage tank 100 to deliver the material delivered to the second material delivery pipeline 220 from the material circulation pipeline 230 to the annular disturbance pipeline 110, and spray it through a plurality of sinking injection mechanisms connected to the annular disturbance pipeline 110. The sinking injection mechanisms are arranged in an annular direction, and the materials sprayed by the sinking injection mechanisms flush and break the storage tank 1 within a certain range. 00 The sediment accumulated at the bottom of the tank 100 can be removed by convection of the material in the tank, which can generate a circumferential rotation motion and play an all-round stirring role. The material can then be output through the first material delivery pipeline 210 and the second material delivery pipeline 220, thereby effectively removing the sediment from the storage tank 100. The output end of the material circulation pipeline 230 is inserted into the interior of the first material delivery pipeline 210, thereby avoiding the drop of the tank wall of the storage tank 100 due to the re-opening of the hole from the side wall of the storage tank 100 or the leakage of the material in the tank due to the welding quality. At the same time, the original material delivery pump is used as the circulating liquid pump 200, which is more energy-saving and reduces costs than the stirring method using an agitator. Through this setting, the present application can cause the material in the tank to convect, generate a circumferential rotation motion, play an all-round stirring role, achieve the purpose of effectively removing the sediment from the storage tank 100, and reduce the stirring cost at the same time.

By setting the flow limiting orifices, it is ensured that the pressure and flow delivered to each sunken nozzle 130 are equivalent, thereby preventing the accumulation of materials on the sides of the bottom sediment. Under the action of the liquid sprayed by the sunken nozzle 130, the sediment at the bottom of the tank is fully flushed and broken up, the stirring intensity of the entire storage tank 100 is basically consistent, there is no dead corner, and the stirring effect is good.
