Embodiment Construction

[0028] The present invention will be described in detail below in conjunction with the accompanying drawings and specific implementation examples.

[0029] The structural representation of the powder fluidized ventilation device provided by the present invention is as follows: figure 1 As shown, the schematic diagram of the porous coil is shown in figure 2 shown.

[0030] The powder fluidization ventilation device includes a porous coil 1, a fixing piece 2, an elbow 3 and a flange 4. The porous coil 1 has a certain number of micropores through machining or laser drilling.

[0031] The material of the porous coil 1 is carbon steel, stainless steel, chromium, nickel, titanium or nickel alloy; the α angle of the porous coil 1 is 0-75°, the pipe diameter 2r is 5-90mm, and the micropore diameter on the surface is 0.01- 8mm, and the opening rate is 0.002-20%. The opening orientation of the micropores is evenly distributed along the circumferential direction of the porous coil, an...

Abstract

The invention provides a powder fluidization venting device which comprises a porous coiled pipe, a fixing part, bends and a flange. The porous coiled pipe is formed by pipelines with micro holes in a spiral mode, the porous coiled pipe is installed on the inner wall of a powder storage tank or a support prearranged in the powder storage tank through the fixing part, and the two ends of each porous coiled pipe section are connected with the bends and connected to the internally connected pipes and externally connected pipes on the powder storage tank through flanges in a welded mode. The powder fluidization venting device can guarantee the fluidization effect of powder and also can solve the problems that powder venting equipment is prone to being damaged and inconvenient to design, machine and overhaul.

Description

technical field [0001] The invention relates to a powder fluidization device for conveying powdery solid materials, in particular to a powder fluidization ventilation device. Background technique [0002] At present, in metallurgy, chemical and cement industries, it is often necessary to transport powdery solid materials. For the transportation of powdery solid materials, if the pre-fluidization method is adopted, the solid-gas ratio of pneumatic conveying can be greatly increased. The premise is to have good ventilation equipment to ensure that the powder can obtain a good fluidization state. If the ventilation equipment is improperly selected or the function is not good, it will cause the powder to be in a poor fluidization state, which will cause the powder to easily accumulate at the bottom of the pipeline during the conveying process; in severe cases, the pipeline will be blocked, making pneumatic conveying impossible. In addition, for the powder conveying device, the ...
