[0003]粉料的储罐一般都带有搅拌结构,使其避免内部粉料发生板结,但是搅拌结构效率较差,粉料的搅拌需要对分料进行更好的鼓动,从而更好的保证粉料的搅拌效果
[0010] The beneficial effects of this utility model are as follows: By setting air inlet pipes on the first and second discharge structures at the bottom, and connecting them with a second auxiliary valve, the gas can be controlled, and the powder can be prevented from flowing back into the air inlet pipes. By injecting nitrogen into the main air inlet pipe, the powder inside the tank is agitated. This, combined with the internal stirring structure, increases the stirring effect of the distributed materials. At the same time, the stirring of the stirring structure is less labor-intensive. In addition, a main air inlet pipe is set at the bottom of the tank, and the main air inlet pipe is connected to the main air inlet pipe through air inlet pipes. This allows nitrogen to be injected into the tank as needed to increase the agitation of the powder inside. The exhaust pipe at the bottom prevents excessive pressure in the tank caused by internal air intake.

Technical Field
[0001] This utility model belongs to the technical field of slurry tank equipment, specifically relating to a nitrogen backflushing device at the bottom of a slurry tank. Background Technology
[0002] Powder storage tanks generally consist of a tank body, inlet and outlet ports, a mixing system, a discharge port, measuring sensors, and a safety system. The tank body is made of steel plate, and the internal components undergo special treatment to ensure the quality and dryness of the powder. Multiple inlet and outlet ports are typically provided for easy addition and removal of the powder. The mixing system uses a horizontal or spiral agitator to ensure thorough mixing of the powder and prevent clumping.
[0003] Powder storage tanks are generally equipped with a stirring structure to prevent the powder from caking inside. However, the stirring structure is not very efficient. The powder needs to be agitated more effectively to ensure better mixing. Summary of the Invention

[0014] The technical solution of this utility model will be further described in detail below through embodiments and in conjunction with the accompanying drawings.
[0015] Example: A nitrogen backflushing device for the bottom of a slurry tank, such as Figures 1-2 As shown, the tank includes a tank body 1. Multiple mounting brackets 14 are provided around the outer ring of the tank body 1. A cover plate 11 is provided on the top of the tank body 1. A stirring structure 12 is provided at the center of the top of the cover plate 11, and the output end of the stirring structure 12 extends through the cover plate 11 into the interior of the tank body 1. An exhaust pipe 13 and multiple auxiliary pipes 15 are respectively provided on one side of the top of the cover plate 11. The exhaust pipe 13 and the auxiliary pipes 15 are connected to the tank body 1. A main air inlet pipe 2 is provided at the center of the bottom of the tank body 1. A first discharge structure 3 and a second discharge structure 4 are respectively provided on both sides of the main air inlet pipe 2. An air inlet branch pipe 37 is connected to the output end of the main air inlet pipe 2, the first discharge structure 3 and the second discharge structure 4. A first auxiliary valve 21 is provided at the connection between the main air inlet pipe 2 and the air inlet branch pipe 37. An air inlet main pipe 5 is connected to the output end of the multiple air inlet branch pipes 37.
[0016] The first discharge structure 3 is the same as the second discharge structure 4. The first discharge structure 3 includes a discharge pipe 31. A valve 33 connecting seat 32 is provided at the bottom of the discharge pipe 31. A valve 33 is provided on one side of the valve 33 connecting seat 32. A discharge pipe 34 is provided at the bottom of the valve 33 connecting seat 32. A discharge auxiliary pipe 35 is connected to one side of the discharge pipe 31. The front side of the discharge auxiliary pipe 35 is connected to the air inlet branch pipe 37, and a second auxiliary valve 33 is provided at the connection between the two. The air inlet main pipe 5 feeds into the three air inlet branch pipes 3. Nitrogen gas is introduced into tank 1 to agitate the powder inside. Nitrogen gas is more stable and will not react with the powder inside. At the same time, a first auxiliary valve 21 and a second auxiliary valve 33 are set to control the amount of air entering the tank. The feeding and discharging are controlled according to the volume of powder inside. Meanwhile, two air inlet pipes 37 are installed on the discharge pipes 31 of the first discharge structure 3 and the second discharge structure 4, respectively. This allows the powder to be agitated by nitrogen gas during subsequent discharge, preventing the powder from accumulating at the connection between the discharge pipe 31 and the tank 1.
