Description

Technical Field

[0001] This utility model relates to the field of powder tank technology, specifically to a powder tank anti-clogging component. Background Technology

[0002] In modern industry, particularly in building materials, chemicals, and mining, powder processing is a crucial step. Air classifiers, as key equipment in this process, are responsible for the precise separation of materials of different particle sizes, ensuring that the final product meets the required quality standards. However, in production practice, the stone powder screened by air classifiers often carries a certain amount of moisture, especially when processing raw materials with high moisture content or operating in high-humidity environments.

[0003] When this moist stone powder is introduced into the powder storage tank, the moisture causes the powder particles to stick together. Over time, the powder gradually hardens and binds tightly together, forming a phenomenon known as "caking." Once caking occurs, the discharge port of the powder tank is easily blocked, causing difficulties in discharging, and in severe cases, even complete blockage. This not only significantly reduces the operating efficiency of the production line but also increases the complexity and cost of equipment maintenance. Furthermore, frequent downtime for maintenance can affect the continuity and stability of the entire production process. Of particular concern is that long-term caking can also threaten the structural safety of the powder tank, potentially leading to tank deformation or damage, further exacerbating the difficulty and cost of maintenance.

[0004] Therefore, this application proposes a powder tank anti-clogging component to solve the above-mentioned technical problems. Utility Model Content

[0005] The main purpose of this utility model is to solve the above-mentioned shortcomings and provide a powder tank anti-clogging component to suppress powder caking, keep the discharge port unobstructed, and realize the efficient and stable operation of the powder tank discharge system.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A powder tank anti-clogging component includes: two scrapers symmetrically and rotatably disposed within the inner cavity of the powder tank; two connecting plates fixedly disposed at the top and bottom of the two scrapers, connecting the two scrapers to form a whole; multiple cutting plates evenly arranged vertically between the two scrapers; a rotating bracket assembly fixedly disposed on the inner wall of a conical cylinder at the bottom of the powder tank, wherein the connecting plates disposed at the bottom of the two scrapers are rotatably disposed on the rotating bracket assembly; and a driving assembly fixedly disposed at the top of the powder tank for driving the two scrapers to rotate against the wall.

[0008] Furthermore, the scraper is divided into a vertical part and a bent part. The vertical part is in close contact with the inner wall of the straight cylindrical part of the powder tank, and the bent part is in close contact with the inner wall of the conical part of the powder tank. A rolling roller is rotatably arranged on the side of the vertical part and the bent part near the cylinder wall of the powder tank. Ball teeth are evenly arranged around the outer wall of the rolling roller, and the ball teeth abut against the inner wall of the powder tank.

[0009] Furthermore, the rotating support assembly includes a conical ring fixedly disposed on the inner wall of the powder tank cone, a shaft seat disposed in the center of the conical ring, and a connecting rod uniformly surrounding the outer wall of the shaft seat and fixedly connected to the inner wall of the conical ring, wherein the top of the connecting rod is conical.

[0010] Furthermore, the drive assembly includes a motor fixedly mounted on the top of the powder tank, a reducer fixedly mounted on the top of the powder tank and whose input shaft is operatively connected to the output shaft of the motor, and an input shaft fixedly mounted on the top of the connecting plate near the reducer. The input shaft passes through the top plate of the powder tank and is operatively connected to the output shaft of the reducer.

[0011] Furthermore, the two sides of the cutting plate are tapered and the overall cross-section is spindle-shaped.

[0012] Furthermore, it also includes a vibration generator fixedly installed on the outer wall of the cone-shaped powder tank.

[0013] The beneficial effects of this utility model are reflected in:

[0014] This invention features a rotating assembly consisting of a scraper, connecting plate, and cutting plate mounted against the inner wall of a powder tank. A drive component propels this assembly to rotate. The scraper removes powder clumps from the inner wall, preventing them from adhering and allowing them to fall more easily under their own weight. The cutting plate further breaks down and agitates the scraped powder, disintegrating it into smaller, less clogged units, thus reducing the likelihood of blockage at the tank's outlet. A toothed roller is mounted on the scraper near the inner wall, reducing friction between the scraper and the tank wall while ensuring effective separation of the clumps. A vibration generator on the outer wall of the conical tank further disperses the broken-down powder, making it easier to discharge from the outlet and minimizing the possibility of blockage.

[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0025] like Figure 1-7 As shown, this utility model provides a powder tank anti-clogging component, including:

[0026] Two scrapers 1 are symmetrically and rotate along the wall inside the powder tank 2;

[0027] Two connecting plates 3 are fixedly installed at the top and bottom of the two scraper blades 1, connecting the two scraper blades 1 to form a whole;

[0028] Multiple cutting plates 4 are evenly arranged vertically between two scraper plates 1;

[0029] The rotating bracket assembly 5 is fixedly installed on the inner wall of the cone at the bottom of the powder tank 2, and the connecting plate 3 installed at the bottom of the two scrapers 1 is rotatably installed on the rotating bracket assembly 5.

[0030] The drive assembly 6 is fixedly installed on the top of the powder tank 2 and is used to drive the two scrapers 1 to rotate against the wall.

[0031] When the powder in the powder tank 2 clogs the discharge port due to caking, the drive assembly 6 is activated. The drive assembly 6 drives the entire assembly consisting of scraper 1, connecting plate 3 and cutting plate 4 to rotate around the rotating support assembly 5 inside the powder tank 2. The scraper 1 is used to scrape off the powder that is caking on the inner wall of the powder tank 2, so that it can no longer adhere to the inner wall of the powder tank 2, and thus fall more easily under its own weight. The cutting plate 4 further cuts and agitates the scraped caking powder, breaking it down into smaller caking units, which are less likely to cause blockage of the discharge port of the powder tank 2.

[0032] In one embodiment, the scraper 1 is divided into a vertical part 11 and a bent part 12. The vertical part 11 is in close contact with the inner wall of the straight cylindrical part of the powder tank 2, and the bent part 12 is in close contact with the inner wall of the conical part of the powder tank 2. A rolling roller 7 is rotatably arranged on the side of the vertical part 11 and the bent part 12 near the cylindrical wall of the powder tank 2. Ball teeth 8 are evenly arranged around the outer wall of the rolling roller 7, and the ball teeth 8 abut against the inner wall of the powder tank 2.

[0033] To scrape away the caking powder adhering to the inner wall of the powder tank 2 as much as possible, the scraper 1 should be set to be in close contact with the inner wall of the powder tank 2. However, if the scraper 1 directly abuts against the powder tank 2, it will cause the scraper 1 to rub violently against the inner wall of the powder tank 2 when rotating, which will hinder the rotation of the scraper 1 and generate noise. With this design, the scraper 1 abuts against the inner wall of the powder tank 2 with the help of the rolling roller 7, which reduces the resistance encountered by the scraper 1 when rotating. At the same time, the ball teeth 8 on the rolling roller 7 continuously roll the powder caking on the inner wall of the powder tank 2 during the rotation of the scraper 1, crushing it and separating it from the inner wall, thus ensuring the separation effect of the caking powder on the inner wall of the powder tank 2.

[0034] In one embodiment, the rotating support assembly 5 includes a conical ring 51 fixedly disposed on the inner wall of the cone of the powder tank 2, a shaft seat 52 disposed in the center of the conical ring 51, and a connecting rod 53 uniformly disposed around the outer wall of the shaft seat 52 and fixedly connected to the inner wall of the conical ring 51, wherein the top of the connecting rod 53 is conical.

[0035] When the powder is discharged from the powder tank 2, it will be blocked by the top surface of the connecting rod 53. By setting the top of the connecting rod 53 to be conical, the blocking effect of the connecting rod 53 on the powder during discharge can be reduced.

[0036] In one embodiment, the drive assembly 6 includes a motor 61 fixedly mounted on the top of the powder tank 2, a reducer 62 fixedly mounted on the top of the powder tank 2 with its input shaft drivingly connected to the output shaft of the motor 61, and an input shaft 63 fixedly mounted on the top of the connecting plate 3 near the reducer 62. The input shaft 63 passes through the top plate of the powder tank 2 and is drivingly connected to the output shaft of the reducer 62.

[0037] With this design, after the motor 61 is turned on, the motor 61 amplifies the torque through the reducer 62 and transmits it to the input shaft 63, which drives the input shaft 63 to rotate. The input shaft 63 further drives the entire assembly consisting of the scraper 1, the connecting plate 3, and the cutting plate 4 to rotate, thereby achieving the driving effect.

[0038] In one embodiment, the two sides of the cutting plate 4 are tapered and the overall cross-section is spindle-shaped.

[0039] This design reduces the resistance exerted by the powder on the cutting plate 4 during rotation, making it easier for the cutting plate 4 to pass through the powder.

[0040] In one embodiment, a vibration generator 9 is also included, which is fixedly mounted on the outer wall of the cone-shaped powder tank 2.

[0041] With this design, when the vibration generator 9 is turned on, it drives the outer wall of the cone to vibrate together. The cone transmits the vibration to the powder in the inner cavity, which further breaks down the caking powder that has already been broken down into smaller volumes in the cone, making it easier to be discharged from the discharge port and reducing the possibility of blockage.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

[0043] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indicators will also change accordingly.

[0044] Furthermore, "multiple" refers to two or more. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of a person skilled in the art to implement them. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
