Description

Technical Field

[0001] The utility model relates to the technical field of powder arch breaking, in particular to a flow-aiding spraying device. Background Art

[0002] Silo arching refers to the upward support force formed in a certain material layer due to the effects of gravity, friction, adhesion and other factors on the materials in the silo. When this support force is balanced with the pressure of the materials above the material layer, the material layer below will be in a static equilibrium state, thus forming an arching phenomenon. The arching phenomenon is sometimes also called shed material, silo or bridge;

[0003] The equipment that prevents or destroys arching is called an arch-breaking device. Air discs and air cannons are the two most common arch-breaking devices on the market.

[0004] As the existing devices are used, the shortcomings of this technology are gradually exposed, mainly in the following aspects:

[0005] Existing air discs that aid flow are not suitable for materials with high viscosity, high specific gravity, and severe blockage inside the silo, while air cannons have the problems of high cost and high noise.

[0006] In summary, the prior art obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0008] In order to solve the above problems, the utility model provides the following technical solutions:

[0009] The flow-aiding blowing device comprises an air pipe, the outlet end of the air pipe is connected to a nozzle, a vertical airway is arranged at the bottom of the nozzle, a plurality of oblique downward airways and an oblique upward airway located above the oblique downward airway are arranged on the side wall of the nozzle.

[0010] As an optimized solution, the nozzle is arranged inside the silo and in the area above the discharge port.

[0011] As an optimized solution, an air cavity connected to the air pipe is provided inside the nozzle, and the inlet ends of the vertical airway, the oblique downward airway and the oblique upward airway are all connected to the air cavity.

[0012] As an optimized solution, the inlet end of the oblique upper airway may also be communicated with the oblique lower airway.

[0013] As an optimized solution, the nozzle is located at the center of the silo.

[0014] As an optimized solution, the outlet end of the air pipe is arranged downward, and an external thread is provided on the outer wall of the nozzle near the upper end, and is threadedly connected to the outlet end of the air pipe.

[0015] As an optimized solution, the air pipe includes a horizontal section and a vertical section connected to the horizontal section.

[0016] As an optimized solution, the portion of the air pipe in the horizontal section is connected to the silo side wall flange.

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] This structure can be applied to various materials, and has low cost, low noise, and can better achieve the arch-breaking effect;

[0019] Vertical airways and oblique downward airways can prevent the material from arching at the bottom and sides, and oblique upward airways can prevent the powder from arching at the top;
