Description

Technical Field

[0001] This utility model relates to the field of powder conveying technology, specifically a fluidizing flange device for preventing material blockage at the bottom of a powder silo. Background Technology

[0002] With the rapid development of society, equipment for powder storage and conveying is used most frequently. In order to improve production efficiency, powder is generally stored in silos. However, during the material conveying process, material bridging and blockage may occur at the bottom of the silo. Utility Model Content

[0003] (a) Technical problems to be solved

[0004] To address the aforementioned problems in the prior art, this utility model provides a fluidizing flange device for preventing material blockage at the bottom of a powder silo, which can effectively solve the problems of bridging and blockage, while also improving the conveying speed.

[0005] (II) Technical Solution

[0006] To achieve the above objectives, the main technical solutions adopted by this utility model include:

[0007] A fluidizing flange device for preventing material blockage at the bottom of a powder silo includes a silo and a fluidizing flange installed at the bottom of the silo. Four manually operated throttling check valves are installed at equal angles around the circumference of the fluidizing flange. The fluidizing flange has air inlets that cooperate with the manually operated throttling check valves. The air inlets on the left and right sides are located at one end of the inner cavity of the fluidizing flange and tilted upwards, while the air inlets on the front and rear sides are located at one end of the inner cavity of the fluidizing flange and tilted downwards. This device effectively solves the problems of bridging and material blockage, while also increasing the conveying speed.

[0008] Preferably, the angle between the air intake outlet and the horizontal plane is 45°.

[0009] (III) Beneficial Effects

[0010] This utility model provides a fluidizing flange device for preventing material blockage at the bottom of a powder silo. It has the following features:

[0011] Beneficial effects:

[0012] (1) Pulse compressed air enters the silo through a throttling check valve, which can fluidize the material and solve the problems of material blockage and bridging.

[0013] (2) When the air is discharged from the inclined upward air inlet, it can fluidize the material inside the hopper and avoid material blockage and bridging. When the air is discharged from the inclined downward air inlet, it can increase the material conveying speed. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] like Figure 1-2 As shown, the fluidizing flange device for preventing material blockage at the bottom of the powder silo in this embodiment includes a silo 1 and a fluidizing flange 2 installed at the bottom of the silo 1. Four manually operated check valves 3 are installed at equal angles around the fluidizing flange 2. The fluidizing flange 2 has air inlets 4 that cooperate with the manually operated check valves 3. The air inlets 4 on the left and right sides are located at one end of the inner cavity of the fluidizing flange 2 and tilted upwards, while the air inlets 4 on the front and rear sides are located at one end of the inner cavity of the fluidizing flange 2 and tilted downwards. This device can prevent material blockage and bridging, and can also improve the material conveying speed.

[0019] Furthermore, the angle between the air intake duct 4's outlet and the horizontal plane is 45°.

[0020] Working principle: Pulsed compressed air enters the air inlet 4 through the throttling check valve 3. When the air exits through the upward-sloping air inlet 4, it can fluidize the material inside the hopper 1, preventing blockage and bridging. When the air exits through the downward-sloping air inlet 4, it can increase the material conveying speed.
