Description

Technical Field

[0001] This utility model belongs to the technical field of material guiding devices, and specifically relates to a material guiding structure that can prevent the agglomeration of powdery materials. Background Technology

[0002] In numerous industrial sectors such as chemical, metallurgical, and food processing, spiral auger conveyors are widely used for conveying powdery materials due to their compact structure and ability to achieve closed conveying. However, when conveying powders with high bulk density and a tendency to agglomerate, such as magnetic material powder, ultrafine cement, and special ceramic powder, challenging problems often arise during equipment operation. These powders exhibit significant cohesion between particles, resulting in a dense structure and poor flowability in their packed state. During auger conveyor feeding, the material abruptly transitions from a static storage state to a dynamic conveying state. The lack of an effective transitional guiding structure at the blade initiation leads to localized material accumulation and pressure concentration. Furthermore, the uneven agitation force of the auger blades during initial startup further exacerbates the mutual compression and adhesion between particles, ultimately forming stubborn clumps at the blade initiation that are difficult to break up. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a material guiding structure that can prevent the agglomeration of powdered materials, so as to solve the problems mentioned in the background art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A material guiding structure that can prevent powdery materials from agglomerating includes a auger conveyor. The auger conveyor includes an inner tube and blades mounted on the inner tube. The inner tube runs through the center of the axis and has multiple sets of air holes. The air holes are located at the beginning of the blades and on the side of the blades closer to the material feeding end. Air enters from the end of the inner tube closer to the material feeding end.

[0006] Preferably, the orientation of the pores is opposite to the direction of blade rotation.

[0007] Preferably, an orifice adjustment assembly for adjusting the orifice diameter is installed inside the inner tube. The orifice adjustment assembly includes a blocking element and a locking element. The blocking element is installed on the inner wall of the inner tube corresponding to the orifice, and the locking element is installed between the blocking element and the inner tube.

[0008] Preferably, the blocking component includes an adjusting tube, the outer wall of which contacts the inner wall of the inner tube, an air hole that penetrates the adjusting tube and communicates with the inside of the adjusting tube, and a locking component installed between the blocking component and the inner tube.

[0009] Preferably, when the inner tube and the regulating tube rotate relative to each other, the diameter of the air hole changes, and when the locking element locks, the inner tube and the regulating tube are relatively fixed.

[0010] Preferably, the auger conveyor also includes an outer pipe, an inner pipe rotatably connected to the outer pipe, blades located inside the outer pipe, and air outlets installed on the inner pipe and regulating pipe located outside the outer pipe.

[0011] Preferably, the air outlet includes an external air outlet on the inner pipe and an internal air outlet on the regulating pipe.

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are illustrated in the accompanying drawings, wherein the same or similar symbols denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0022] Example 1

[0023] refer to Figures 1 to 4 The material guiding structure described in this embodiment, which can prevent the agglomeration of powdery materials, includes a auger conveyor 1. The auger conveyor 1 includes a drive device 11, an outer tube 12, an inner tube 13, and blades 14. The blades 14 are installed on the inner tube 13. The outer tube 12 is sleeved on the outside of the inner tube 13 and wraps around the blades 14. One end of the inner tube 13 passes through the outer tube 12 and is installed on the output end of the drive device 11. The two ends of the outer tube 12 are the feed end and the discharge end, respectively. The top of the feed end is equipped with a funnel 6 that communicates with the inside of the outer tube 12. The bottom of the discharge end is equipped with an output port 7 that communicates with the inside of the outer tube 12. This structure is prior art and will not be described in detail. Unlike the traditional auger conveyor 1, the inner tube 13 of this structure runs through the axial direction. Multiple sets of air holes 5 are opened through the inner tube 13. The air holes 5 are located at the beginning of the blades 14 and on the side of the blades 14 near the discharge end. The inner tube 13 is inlet air near the funnel 6.

[0024] When the powdery material enters the outer tube 12 from the funnel 6, it suddenly changes from a static storage state to a dynamic conveying state. During the conveying process, due to its high bulk density, it is easy to accumulate at the connection between the blade 14 and the inner tube 13. Therefore, air is introduced into the inner tube 13, and the airflow pushes the powdery material at the beginning of the blade 14 through the air hole 5 to prevent accumulation.

[0025] It is worth noting that the orientation of the vent 5 is opposite to the rotation direction of the blade 14. For example, when looking from the feed inlet to the discharge outlet, when the blade 14 rotates clockwise, the vent 5 should face the upper left and point to the inside of the blade 14. The orientation of the vent 5 is opposite to the material movement. The airflow interferes with the spiral movement of the powder material, thereby impacting the material and preventing the powder material from accumulating at the beginning of the blade 14.

[0026] An orifice adjustment assembly for adjusting the orifice diameter of the air hole 5 is installed inside the inner tube 13. The orifice adjustment assembly includes a blocking member and a locking member 3. The blocking member is installed on the inner wall of the inner tube 13 corresponding to the air hole 5, and the locking member 3 is installed between the blocking member and the inner tube 13.

[0027] Preferably, the blocking component includes an adjusting tube 2, the outer wall of the adjusting tube 2 is in contact with the inner wall of the inner tube 13, the air hole 5 passes through the adjusting tube 2 and communicates with the inside of the adjusting tube 2, and the locking component 3 is installed between the blocking component and the inner tube 13 and is located outside the outer tube 12. When the inner tube 13 and the adjusting tube 2 rotate relative to each other, the size of the air hole 5 changes. When the locking component 3 is locked, the inner tube 13 and the adjusting tube 2 are relatively fixed.

[0028] Preferably, as shown in the figure, the locking component 3 includes a tightening bolt and a sleeve. When the bolt is tightened, the bolt passes through the inner tube 13 and squeezes the regulating tube 2, so that the inner tube 13 and the regulating tube 2 are relatively fixed. When the bolt is loosened, the bolt is taken out from the inner tube 13, and the inner tube 13 and the regulating tube 2 can rotate relative to each other. When they rotate relative to each other, the overlapping position of the air hole 5 on the regulating tube 2 and the air hole 5 on the inner tube 13 changes, thereby changing the size of the air outlet diameter.

[0029] An air outlet 8 is installed on the inner pipe 13 and the regulating pipe 2 located outside the outer pipe 12. This outlet is used to regulate the air speed and prevent the air speed from being too high. The inner diameter of the air hole 14 is small, so the airflow cannot escape from the inner pipe 13, which would cause the powder in the outer pipe 12 to scatter.

[0030] Specifically, the air outlet 8 includes an external air outlet 81 opened on the inner pipe 13 and an internal air outlet 82 opened on the regulating pipe 2. The diameter of the external air outlet 81 is larger than that of the internal air outlet 82, and the internal air outlet 82 is always located within the projection range of the external air outlet 81. The diameter of the internal air outlet 82 is adjustable, for example, by using a valve.

[0031] The above is just one embodiment of the aperture adjustment component. Other suitable blocking components can also be used to block or open the diameter of the air hole 5 on the inner tube 13.

[0032] An air inlet device 4 is installed at the end of the inner tube 13 near the feed end, and the end of the inner tube 13 near the discharge end is installed on the output shaft of the drive device 11. In the above embodiment, the regulating pipe 2 is rotatably installed at the air outlet of the air inlet device 4. The air inlet device 4 can be a blower or other device used for blowing air.

[0033] An anti-clogging mesh 51 is installed on the air hole 5 to prevent powder from entering the inner tube 13.

[0034] Working principle: According to the actual situation, loosen the locking piece 3, rotate the regulating pipe 2, adjust the size of the air hole 5 to allow airflow, lock the locking piece 3 after adjustment, start the drive device 11 and the air inlet device 4, the inner pipe 13 drives the blade 14 to rotate, the air inlet device 4 blows air into the inner pipe 13, the airflow blows from the air hole 5 to the inside of the blade 14, the blade 14 rotates in the opposite direction to the air hole 5, the powder enters from the funnel 6, when the blade 14 is conveyed, the airflow blows the powder to prevent the powder from agglomerating at the beginning of the blade 14, the excess airflow escapes from the inner air outlet 82, and the powder finally flows out of the auger conveyor 1 from the output port 7.

[0035] This device sets the central shaft of the auger conveyor 1 as an inner tube 13 and opens air holes 5 on the inner tube 13 to blow air into the inner tube 13. The airflow is opposed to the direction of powder movement to prevent the powder material from agglomerating.
