As used herein, the term "and/or" includes any and all combinations of one or more of the associated listed items.
Referring to fig. 1, an embodiment of the present application provides a fine powder bin with an anti-blocking function, including a bin body 1, a bin 13 is provided inside the bin body 1, a feeding port 2 communicated with the bin 13 is provided on the top of the bin body 1, a discharging port 3 communicated with the bin 13 is provided on the bottom of the bin body 1, a bin wall of the bin body 1 is of an interlayer structure 4, and an air distribution cavity 45 is provided in the interlayer, in the interlayer structure 4, an air inlet 43 communicated with the air distribution cavity 45 is provided on an outer wall 41 of the interlayer, and an air outlet 44 communicated with the bin 13 is provided on an inner wall 42 of the interlayer.
The external device of storehouse body 1 inputs gas into air distribution chamber 45 from air intake 43, and gas flows in air distribution chamber 45 and flows out from air outlet 44 and gets into bin 13, makes and forms the stranded air current in bin 13, and the fine powder is constantly dispersed under the effect of air current, prevents because of the electrostatic effect gathering in the unloading region between the granule of fine powder, has improved the mobility of fine powder. The air flow speed is controlled to control the fine powder blanking speed, the faster the air flow speed is, the volume expansion of the corresponding area and the pressure reduction are realized, so that the fine powder is not easy to accumulate rapidly, and the bridging phenomenon at the blanking port 3 is effectively solved.
In one embodiment, the bin body 1 comprises a straight section 11 and a conical section 12 from top to bottom, and the conical section 12 at least gradually reduces from top to bottom to the feed opening 3. The falling process of the fine powder is in a funnel shape, namely the fine powder in the position, right above the feed opening 3, of the bin 13 flows fast, the fine powder on two sides flows slowly, the conical section 12 can lead the fine powder to be fed intensively, and meanwhile, the fine powder is prevented from remaining at the edge corners of the bin 13.
However, as the diameter of the bin body 1 is continuously reduced from top to bottom, fine powder is easily accumulated in the feed opening 3 and the area near the upper part of the feed opening 3, so that the feed opening 3 is blocked, and the feeding efficiency is seriously influenced; to solve this problem, in one embodiment, the straight section 11 and the tapered section 12 both use the sandwich structure 4. The air outlet 44 on the conical section 12 is at a certain angle, so that the air flow of the air outlet 44 is output along a certain angle, convection is formed above the feed opening 3, fine powder accumulation or stable bridging above the feed opening is prevented, and the flowability of the fine powder is improved.
Furthermore, a plurality of vibrators 5 can be arranged on the conical section 12 close to the blanking port 3, the vibrators 5 can be uniformly arranged along the outer wall 41 of the interlayer, fine powder adhered to the inner wall 42 of the interlayer falls off through a vibration mode, meanwhile, the fine powder in the blanking port 3 quickly falls into the vibrating screen 6, and the vibrating screen 6 conveys the fine powder to the discharging auger 7 below.
In order to further improve the flowability of the fine powder in the bin body, in one embodiment, a plurality of the air inlets 43 are uniformly arranged at intervals along the circumferential direction of the bin body 1. The air inlets simultaneously supply air, so that the whole bin body 1 is quickly filled with flowing air flow, and the air flow quickly expands the volume of fine powder in the bin 13, thereby effectively preventing the fine powder from being accumulated at the feed opening 3.
Furthermore, the height positions of the air inlets 43 are parallel and level with each other, stable air flow is formed along the circumferential direction of the sandwich structure 4, and the bin body is prevented from being damaged by overlarge local air flow.
The position of the air inlet affects the gas shunting effect, in one embodiment, the air inlet 43 is located in the straight cylinder section 11, and is adjacent to the conical section 12 in height, so that the air flow in the conical section 12 is larger than that in the straight cylinder section 11, the volume of the corresponding area of the conical section 12 expands, the pressure is reduced, fine powder is not easy to accumulate at the feed opening 3 quickly, and the bridging phenomenon is avoided.
In order to guide the flow direction of the air flow in the air distribution chamber 45, the interlayer outer wall 41 is provided with a flow guide 46 for guiding the air flow direction on the side facing the air distribution chamber 45.
The diversion member 46 can also change the direction of the airflow at the air outlet 44. in one embodiment, the diversion member 46 is a corrugated plate attached and fixed to the outer wall 41 of the interlayer. The air current circulates at air distribution cavity 45 and constantly shunts from air outlet 44 of intermediate layer inner wall 42, and the buckled plate has continuous arch towards intermediate layer inner wall 42, can guide the air current to export towards the air outlet position, and the arrow shows the air current direction in the wind gap in figure 1, forms the circulating air current in the bin, makes the motion of fine powder accelerate, is difficult for forming stable arch bridge.
The structure of the air outlet 44 affects the gas distribution and changes the state of the air flow in the bin 13, in one embodiment, the air outlet 44 is provided with a plurality of groups on the interlayer inner wall 42 along the circumferential direction of the bin body 1, and any two adjacent groups are respectively a large hole group 441 and a small hole group 442; the large hole group 441 and the small hole group 442 cooperate to further disturb the movement of the fine powder.
To further enhance the flowability of the powder, in one embodiment, the same set of holes are spaced vertically along the interior wall 42 of the sandwich, see FIG. 2.
In this embodiment, the diameter of each hole in the large hole group 441 is 4-6 mm, the diameter of each hole in the small hole group 442 is 1-3 mm, and the vertical arrangement interval of each hole in the same group is 5-10 mm.
The technical features of the embodiments described above may be arbitrarily combined, and for the sake of brevity, all possible combinations of the technical features in the embodiments described above are not described, but should be considered as being within the scope of the present specification as long as there is no contradiction between the combinations of the technical features. When technical features in different embodiments are represented in the same drawing, it can be seen that the drawing also discloses a combination of the embodiments concerned.
The above-mentioned embodiments only express several embodiments of the present application, and the description thereof is more specific and detailed, but not construed as limiting the scope of the utility model. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the concept of the present application, which falls within the scope of protection of the present application. Therefore, the protection scope of the present application shall be subject to the appended claims.
