Description

Technical Field

[0001] This invention relates to the field of powder feeding technology, and in particular to a powder arch-breaking feeding device. Background Technology

[0002] During the use of powder feeding equipment, the discharge port is prone to arching or blockage. As disclosed in Chinese Patent No. CN 102502127A, a scraper-type anti-blockage feeding hopper is designed to prevent this problem. By adding a rotating body inside the discharge port, a separation zone is formed during its movement, preventing the powder from forming an arch and effectively avoiding blockage. Furthermore, the rotating body's agitator prevents the powder in the fixed upper part of the hopper from creating a dead flow zone near the hopper wall, reducing the likelihood of blockage in the upper part of the hopper. In other words, the scraper of the rotating body is installed in the easily blocked areas of the hopper, not only solving the material blockage problem in those areas but also effectively improving the flow of materials throughout the entire hopper, alleviating the problem of material adhering to the walls in other parts of the hopper.

[0003] However, from the aforementioned scraper-type anti-clogging feed hopper Figure 1 It is known that a certain gap exists between the mixing body and the inner wall of the feeding hopper, making it impossible to completely scrape off the powder adhering to the inner wall of the feeding hopper, resulting in low material utilization. To solve the above technical problems, a new type of scraper mechanism has emerged on the market. For example, Chinese Patent No. CN 116101645A discloses a scraper mechanism for loosening raw coal silos; by adding an air-jet scraper, the powder adhering to the inner wall of the feeding hopper can be effectively scraped off.

[0004] However, from the scraper mechanism used for loosening materials in the aforementioned raw coal bunker... Figure 3 and Figure 7 As can be seen, the airflow scraper component (31) includes multiple connecting plates (311) with their top ends connected to the inner wall of the bottom rotating ring (22), and an air jet scraper (312) located at the bottom of the connecting plates (311). The air jet scraper (312) is attached to the inner wall of the funnel hopper (12). That is, the rotating ring, connecting plates, and air jet scraper are all located at the upper part of the funnel-shaped discharge end of the powder hopper, resulting in the rotating ring, connecting plates, and air jet scraper occupying a large amount of internal space in the funnel powder hopper, thereby reducing the space utilization rate of the funnel powder hopper. In addition, the air jet scraper is horizontally arranged inside the funnel-shaped discharge end, which makes it easy for the horizontally arranged air jet scraper to block the discharge of materials, thereby affecting the discharge effect of the powder hopper. Summary of the Invention

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a powder arch breaking and feeding device that improves the space utilization rate of the funnel powder silo, facilitates the discharge of the funnel powder silo, has a simple structure, and reduces the rotational interference of the spiral sickle arch breaking plate during arch breaking, thereby reducing the rotational energy consumption of the rotating cylinder and the spiral sickle arch breaking plate and reducing the probability of the spiral sickle arch breaking plate breaking.

[0006] The objective of this invention is achieved through the following technical solution:

[0007] A powder arch-breaking and feeding device includes a funnel-shaped powder hopper, a rotating cylinder, a funnel-shaped receiving hopper, a valve body, an inner scraper for arch breaking, a fixing assembly, and a driving assembly.

[0008] The funnel powder hopper, the rotating cylinder, and the funnel receiving hopper are connected in sequence from top to bottom; the valve body is disposed between the rotating cylinder and the funnel receiving hopper.

[0009] The first end of the rotating cylinder is rotatably disposed at the funnel-shaped discharge end of the funnel powder hopper and forms a first connection point; the second end of the rotating cylinder is rotatably disposed at the feed end of the funnel receiving hopper and forms a second connection point.

[0011] The arch-breaking inner rotating scraper includes a connecting inclined platform and a spiral sickle arch-breaking plate. One side of the connecting inclined platform is disposed on the inner wall of the rotating cylinder, and one end of the connecting inclined platform is connected to the spiral sickle arch-breaking plate. The connecting inclined platform, the spiral sickle arch-breaking plate, and the inner wall of the rotating cylinder together form an arch-breaking inclined discharge channel.

[0013] In one embodiment, the end of the rotating cylinder facing the funnel-shaped feeding end is recessed to form a rotating locking groove; the funnel-shaped feeding end is rotatably disposed within the rotating locking groove.

[0014] In one embodiment, the end of the connecting tilting platform facing the funnel-shaped feeding end is recessed to form a rotating groove, and the rotating groove is connected to the rotating snap-fit ​​groove.

[0015] In one embodiment, the connecting tilting platform is a triangular connecting tilting platform; the first surface of the triangular connecting tilting platform is disposed on the inner wall of the rotating cylinder; the second surface of the triangular connecting tilting platform is inclined to the inner wall of the rotating cylinder to form a first arch-breaking tilting discharge sub-area; the third surface of the triangular connecting tilting platform is inclined to the inner wall of the rotating cylinder to form a second arch-breaking tilting discharge sub-area, and the first arch-breaking tilting discharge sub-area and the second arch-breaking tilting discharge sub-area together form an arch-breaking tilting discharge channel.

[0016] In one embodiment, the extension direction of the second face of the triangular connecting tilting platform is connected to the circumferential direction of the inner wall of the rotating cylinder to form a predetermined obtuse angle; and / or,

[0017] The extension direction of the third face of the triangular connecting tilting platform is connected to the circumferential direction of the inner wall of the rotating cylinder to form a preset acute angle.

[0018] In one embodiment, the spiral sickle-shaped arch-breaking plate includes a spiral inclined scraping abutment portion and a spiral inclined piercing portion; the spiral inclined piercing portion is connected to the connecting inclined platform via the spiral inclined scraping abutment portion; and / or

[0019] The fixing component further includes a fixing seat, the first end of which is sleeved on the outer peripheral wall of the funnel-shaped feeding end and threadedly connected to the first fixing ring; the second end of the fixing seat is connected to the feeding end of the funnel receiving hopper.

[0020] In one embodiment, the powder arch-breaking and feeding device further includes a first bearing and a second bearing, wherein the first bearing is disposed between the first fixed ring and the first end of the rotating cylinder; and the second bearing is disposed between the second fixed ring and the second end of the rotating cylinder.

[0021] In one embodiment, the powder arch-breaking and feeding device further includes a first airbag sealing ring; the first airbag sealing ring is disposed between the first fixed ring and the first end of the rotating cylinder, and the first airbag sealing ring is used to seal the first connection; and / or,

[0022] The powder arch-breaking and feeding device further includes a second airbag sealing ring; the second airbag sealing ring is disposed between the second fixed ring and the second end of the rotating cylinder, and the second airbag sealing ring is used to seal the second connection.

[0023] In one embodiment, the large gear is located in the middle of the outer peripheral wall of the rotating cylinder.

[0024] In one embodiment, the powder arch-breaking and feeding device further includes a second driver; the feed end of the funnel receiving hopper is formed with a feed port, and the rotating plate of the valve body is rotatably disposed in the funnel receiving hopper; the rotating plate is used to close the feed port, and the rotating plate is connected to the driving end of the second driver; the second driver is disposed at the end of the feed end of the funnel receiving hopper.

[0025] Compared with the prior art, the present invention has at least the following advantages:

[0026] 1. Since the funnel-shaped powder hopper, the rotating cylinder, and the funnel-shaped receiving hopper are sequentially connected from top to bottom, the first end of the rotating cylinder is rotatably positioned at the funnel-shaped discharge end of the funnel-shaped powder hopper, and the second end of the rotating cylinder is rotatably positioned at the inlet end of the funnel-shaped receiving hopper; this allows the rotating cylinder to be located at the funnel-shaped discharge end at the bottom of the funnel-shaped powder hopper, and the rotating cylinder extends the discharge space of the funnel-shaped discharge end, which is beneficial for material discharge; furthermore, since one side of the connecting inclined platform is located on the inner wall of the rotating cylinder, the connecting inclined platform... One end is connected to the spiral sickle arch-breaking plate, connecting the inclined platform, the spiral sickle arch-breaking plate, and the rotating cylinder; the spiral sickle arch-breaking plate extends into the funnel-shaped discharge end and movably abuts against the inner wall of the funnel-shaped discharge end. In this way, only the spiral sickle arch-breaking plate extends into the funnel-shaped discharge end, effectively reducing the internal space occupied by the funnel powder silo, thereby improving the space utilization rate of the funnel powder silo; in addition, the inclined platform and the spiral sickle arch-breaking plate are connected and together form an arch-breaking inclined discharge channel, which is beneficial to the discharge of the funnel powder silo.

[0027] 2. Compared with the traditional rotating ring, the rotating cylinder has a larger area than the rotating ring, which enables the rotating cylinder of this disclosure to provide reliable and stable structural support for the spiral sickle arch-breaking plate, effectively avoiding the easy breakage of the spiral sickle arch-breaking plate.

[0028] 3. Since one side of the connecting tilting platform is located on the inner wall of the rotating cylinder, and one end of the connecting tilting platform is connected to the spiral sickle arch-breaking plate, the spiral sickle arch-breaking plate is located on one side of the rotating cylinder, ensuring that the spiral sickle breaks the arch in an eccentric manner. This reduces the arch-breaking force of the spiral tilting piercing part and further reduces the probability of the spiral sickle arch-breaking plate breaking.

[0029] 4. In practical applications, powder arching is prone to occur at the contraction point of the traditional funnel-shaped feeding end. Since most powder arching structures are upward-curving, and the traditional air-jet scraper is located above the funnel-shaped feeding end, placing it on the convex surface of the powder arch, the scraper experiences a greater breaking force, increasing the probability of scraper breakage. Furthermore, additional auxiliary components are required to assist in the breaking effect, making the traditional breaking structure complex. Therefore, this disclosure places the rotating cylinder below the funnel-shaped feeding end, positioning the spiral sickle-shaped breaking plate on the concave surface of the powder arch structure. This reduces the force exerted by the spiral sickle-shaped breaking plate on the concave surface compared to the convex surface. Thus, the arched powder structure can be broken without the need for additional air-carrying components, simplifying the structure and further reducing the probability of spiral sickle-shaped breaking plate breakage. This is particularly suitable for applications involving viscous powders with arched structures.

[0030] 5. Since the first end of the rotating cylinder is rotatably disposed at the funnel-shaped discharge end of the funnel powder hopper and forms a first connection point; the second end of the rotating cylinder is rotatably disposed at the inlet end of the funnel receiving hopper and forms a second connection point, the rotating cylinder can be detachably disposed with the funnel-shaped discharge end and the inlet end of the funnel receiving hopper respectively; and since the first fixing ring is sleeved on the first connection point and is detachably connected to the funnel-shaped discharge end; and the second fixing ring is sleeved on the second connection point and is detachably connected to the inlet end of the funnel receiving hopper, the rotating cylinder can be detachably fixed, thereby facilitating the operator to disassemble and assemble the rotating cylinder to replace a damaged rotating cylinder or a suitable rotating cylinder.

The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0043] To better understand the technical solutions and beneficial effects of this disclosure, the following detailed description is provided in conjunction with specific embodiments:

[0044] Please see Figures 1 to 3 One embodiment of the powder arch-breaking and feeding device 10 includes a funnel-shaped powder hopper 100, a rotating cylinder 200, a funnel-shaped receiving hopper 300, a valve body 400, an inner scraper body 500 for arch breaking, a fixing component 600, and a driving component. The funnel-shaped powder hopper 100, the rotating cylinder 200, and the funnel-shaped receiving hopper 300 are sequentially connected from top to bottom. The valve body 400 is disposed between the rotating cylinder 200 and the funnel-shaped receiving hopper 300. The first end of the rotating cylinder 200 is rotatably disposed at the funnel-shaped feeding end 110 of the funnel-shaped powder hopper 100 and forms a first connection 210. The second end of the rotating cylinder 200 is rotatably disposed at the feeding end of the funnel-shaped receiving hopper 300 and forms a second connection 220.

[0045] The fixing component 600 includes a first fixing ring 610 and a second fixing ring 620. The first fixing ring 610 is sleeved on the first connection 210 and is detachably connected to the funnel-shaped discharge end 110. The second fixing ring 620 is sleeved on the second connection 220 and is detachably connected to the feed end of the funnel receiving bin 300. The arch-breaking inner rotating scraper 500 includes a connecting inclined platform 510 and a spiral sickle arch-breaking plate 520. One side of the connecting inclined platform 510 is disposed on the inner wall of the rotating cylinder 200, and one end of the connecting inclined platform 510 is connected to the spiral sickle arch-breaking plate 520. The connecting inclined platform 510, the spiral sickle arch-breaking plate 520, and the inner wall of the rotating cylinder 200 together form an arch-breaking inclined discharge channel 530. Please refer to the following: Figure 5The spiral sickle arch-breaking plate 520 extends into the funnel-shaped feeding end 110 and movably abuts against the inner wall of the funnel-shaped feeding end 110; the driving assembly includes a first driver 710, a large gear 720, and a small gear 730; the first driver 710 is disposed on the funnel receiving bin 300, and the driving end of the first driver 710 is provided with the small gear 730; the large gear 720 is sleeved on the outer peripheral wall of the rotating cylinder 200, and the large gear 720 meshes with the small gear 730 for transmission.

[0046] It is understood that, since the funnel powder hopper 100, the rotating cylinder 200, and the funnel receiving hopper 300 are sequentially connected from top to bottom, the first end of the rotating cylinder 200 is rotatably disposed at the funnel-shaped discharge end 110 of the funnel powder hopper 100, and the second end of the rotating cylinder 200 is rotatably disposed at the inlet end of the funnel receiving hopper 300; this allows the rotating cylinder 200 to be located at the funnel-shaped discharge end 110 at the bottom of the funnel powder hopper 100, and the rotating cylinder 200 extends the discharge space of the funnel-shaped discharge end 110, which is beneficial for material discharge; furthermore, since one side of the connecting inclined platform 510 is disposed on the inner wall of the rotating cylinder 200, and one end of the connecting inclined platform 510 is connected to... The spiral sickle arch-breaking plate 520 connects the tilting platform 510, the spiral sickle arch-breaking plate 520, and the rotating cylinder 200 to form an arch-breaking inclined discharge channel 530. The spiral sickle arch-breaking plate 520 extends into the funnel-shaped discharge end 110 and moves against the inner wall of the funnel-shaped discharge end 110. In this way, by extending the spiral sickle arch-breaking plate 520 into the funnel-shaped discharge end 110, the internal space occupied by the funnel powder silo 100 is effectively reduced, thereby improving the space utilization rate of the funnel powder silo 100. In addition, the connection between the tilting platform 510 and the spiral sickle arch-breaking plate 520 to form the arch-breaking inclined discharge channel 530 is beneficial to the discharge of material from the funnel powder silo 100.

[0047] Compared with the traditional rotating ring, the rotating cylinder 200 of this disclosure has higher structural strength. Since the area of ​​the rotating cylinder 200 is larger than that of the rotating ring, the rotating cylinder 200 of this disclosure can provide reliable and stable structural support for the spiral sickle arch-breaking plate 520, effectively avoiding the phenomenon that the spiral sickle arch-breaking plate 520 is prone to breakage.

[0048] Since one side of the connecting tilting platform 510 is located on the inner wall of the rotating cylinder 200, and one end of the connecting tilting platform 510 is connected to the spiral sickle arch-breaking plate 520, the spiral sickle arch-breaking plate 520 is located on one side of the rotating cylinder 200, ensuring that the spiral sickle breaks the arch in an eccentric manner. In this way, the arch-breaking force of the spiral tilting piercing part 522 is reduced, further reducing the probability of the spiral sickle arch-breaking plate 520 breaking.

[0049] In practical applications, powder bridging is prone to occur at the contraction point of the traditional funnel-shaped feeding end 110; and the bridging structure of most powders is upward arching, such as... Figure 7 As shown, traditional air-jet scrapers are located above the funnel-shaped feeding end 110, placing them on the convex surface of powder arching. This results in a larger arch-breaking force on the air-jet scraper, increasing the probability of its breakage. Furthermore, additional auxiliary components are required to assist in its arch-breaking effect, making the traditional arch-breaking structure more complex. Therefore, this disclosure places the rotating cylinder 200 below the funnel-shaped feeding end 110, positioning the spiral sickle arch-breaking plate 520 on the concave surface of the powder arching structure. This reduces the force exerted by the spiral sickle arch-breaking plate 520 on the concave surface compared to the convex surface. Thus, the arched powder structure can be broken without the need for additional air-carrying components, simplifying the structure and further reducing the probability of breakage of the spiral sickle arch-breaking plate 520. This is particularly suitable for applications involving viscous powder arching structures.

[0050] It is worth mentioning that, since the traditional rotating ring, connecting plate and air-jet scraper are all located inside the funnel powder hopper 100, the rotation of the rotating ring, connecting plate and air-jet scraper is easily affected by the viscous powder inside the funnel powder hopper 100, resulting in high overall rotational energy consumption of the rotating ring, connecting plate and air-jet scraper, thereby increasing the probability of breakage of the rotating ring, connecting plate and air-jet scraper. Therefore, by setting the spiral sickle arch-breaking plate 520 and the rotating cylinder 200 at the funnel-shaped feeding end 110, especially in conjunction with the funnel-shaped feeding end 110, the present disclosure makes it easy for viscous powder to form an arch structure within the funnel-shaped feeding end 110. The resulting arch structure can effectively block some of the viscous powder from entering the rotating cylinder 200, ensuring that the amount of viscous powder entering the rotating cylinder 200 is relatively small. In this way, the interference of viscous powder on the rotation of the rotating cylinder 200 and the spiral sickle arch-breaking plate 520 is effectively reduced, thereby reducing the rotational energy consumption of the rotating cylinder 200 and the spiral sickle arch-breaking plate 520, and further reducing the probability of the spiral sickle arch-breaking plate 520 breaking.

[0051] Since the first end of the rotating cylinder 200 is rotatably disposed at the funnel-shaped discharge end 110 of the funnel powder hopper 100 and forms a first connection 210; the second end of the rotating cylinder 200 is rotatably disposed at the feed end of the funnel receiving hopper 300 and forms a second connection 220, the rotating cylinder 200 is detachably disposed from both the funnel-shaped discharge end 110 and the feed end of the funnel receiving hopper 300; and since the first fixing ring 610 is sleeved on the first connection 210 and is detachably connected to the funnel-shaped discharge end 110; and the second fixing ring 620 is sleeved on the second connection 220 and is detachably connected to the feed end of the funnel receiving hopper 300, the rotating cylinder 200 is detachably fixed, thereby facilitating the operator to disassemble and assemble the rotating cylinder 200 to replace a damaged rotating cylinder 200 or a compatible rotating cylinder 200.

[0052] like Figure 4 and Figure 5 As shown, in one embodiment, the rotating cylinder 200 has a rotating locking groove 230 recessed at one end facing the funnel-shaped feeding end 110. The funnel-shaped feeding end 110 is rotatably disposed in the rotating locking groove 230, so that the rotating cylinder 200 can sleeve and wrap around the funnel-shaped feeding end 110, thereby realizing the rotating arrangement of the rotating cylinder 200 and the funnel-shaped feeding end 110.

[0053] like Figure 4 and Figure 5 As shown, in one embodiment, the end of the connecting tilting platform 510 facing the funnel-shaped feeding end 110 is recessed to form a rotating groove 513, which is connected to the rotating locking groove 230. The added rotating groove 513 increases the rotation space between the connecting tilting platform 510 and the funnel-shaped feeding end 110, ensuring that the connecting tilting platform 510 is less likely to jam with the funnel-shaped feeding end 110 during rotation, and ensuring that the inner rotating scraper body 500 of the arch breaker can rotate smoothly at the funnel-shaped feeding end 110.

[0054] like Figure 4 and Figure 5 As shown, in one embodiment, the connecting tilting platform 510 is a triangular connecting tilting platform 510; the first surface of the triangular connecting tilting platform 510 is disposed on the inner wall of the rotating cylinder 200; the second surface 511 of the triangular connecting tilting platform 510 is inclined to the inner wall of the rotating cylinder 200 to form a first arch-breaking tilting discharge sub-area 531; the third surface 512 of the triangular connecting tilting platform 510 is inclined to the inner wall of the rotating cylinder 200 to form a second arch-breaking tilting discharge sub-area 532, and the first arch-breaking tilting discharge sub-area 531 and the second arch-breaking tilting discharge sub-area 532 together form an arch-breaking tilting discharge channel 530.

[0055] It is understandable that, since the connecting tilting platform 510 is a triangular connecting tilting platform 510, the triangular connecting tilting platform 510 can provide more stable support for the spiral sickle arch-breaking plate 520, thereby ensuring the reliability and stability of the rotation of the spiral sickle arch-breaking plate 520; on the other hand, since the triangular connecting tilting platform 510 has a smaller exposed area on the inner wall of the rotating cylinder 200 compared to the square connecting tilting platform 510, the exposed area of ​​the connecting tilting platform 510 is minimized, thereby effectively avoiding the phenomenon of serious material accumulation caused by the large exposed area of ​​the connecting tilting platform 510.

[0056] In other words, the first surface of the triangular connecting inclined platform 510 is disposed on the inner wall of the rotating cylinder 200, thereby connecting the triangular connecting inclined platform 510 with the inner wall of the rotating cylinder 200; the second surface 511 of the triangular connecting inclined platform 510 is inclined to the inner wall of the rotating cylinder 200 to form a first arch-breaking inclined discharge sub-area 531; the third surface 512 of the triangular connecting inclined platform 510 is inclined to the inner wall of the rotating cylinder 200 to form a second arch-breaking inclined discharge sub-area 532. The first arch-breaking inclined discharge sub-area 531 and the second arch-breaking inclined discharge sub-area 532 together form an arch-breaking inclined discharge channel 530. The second surface 511 of the triangular connecting inclined platform 510 and the inner wall of the rotating cylinder 200 form a first arch-breaking inclined discharge sub-area 531, and the third surface 512 of the triangular connecting inclined platform 510 and the inner wall of the rotating cylinder 200 form a second arch-breaking inclined discharge sub-area 532. The first arch-breaking inclined discharge sub-area 531 and the second arch-breaking inclined discharge sub-area 532 together form an arch-breaking inclined discharge channel 530. This ensures that the first arch-breaking inclined discharge sub-area 531 and the second arch-breaking inclined discharge sub-area 532 of the arch-breaking inclined discharge channel 530 are not prone to material accumulation, thereby improving the utilization rate of powder materials.

[0057] In one embodiment, the extension direction of the second surface 511 of the triangular connecting tilting platform 510 is connected to the circumferential direction of the inner wall of the rotating cylinder 200 at a preset obtuse angle; this ensures that the second surface 511 of the triangular connecting tilting platform 510 and the inner wall of the rotating cylinder 200 form a suitable tilt setting. Thus, while ensuring that the area of ​​the second surface 511 of the triangular connecting tilting platform 510 exposed on the inner wall of the rotating cylinder 200 is as small as possible, it also ensures that the second surface 511 of the triangular connecting tilting platform 510 can provide stable support for the spiral sickle arch-breaking plate 520.

[0058] Similarly, in one embodiment, the extension direction of the third surface 512 of the triangular connecting tilting platform 510 is connected to the circumferential direction of the inner wall of the rotating cylinder 200 to form a preset acute angle; thus, while ensuring that the area of ​​the third surface 512 of the triangular connecting tilting platform 510 exposed on the inner wall of the rotating cylinder 200 is as small as possible, it is also ensured that the third surface 512 of the triangular connecting tilting platform 510 can provide stable support for the spiral sickle arch-breaking plate 520.

[0059] like Figure 6 As shown, in one embodiment, in order to ensure that the triangular connecting tilting platform 510 can provide reliable and stable support for the spiral sickle arch-breaking plate 520, while also maximizing the exposure area of ​​the second surface 511 and the third surface 512 of the triangular connecting tilting platform 510, so as to minimize the problem of material accumulation on the second surface 511 and the third surface 512 of the triangular connecting tilting platform 510. Therefore, this disclosure sets the preset obtuse angle to 110°~135° and the preset acute angle to 5°~35°. The side lengths of the cross section of the triangular connecting tilting platform 510 are a-side 514, b-side 515 and c-side 516, respectively. The side length of side a is a, the side length of side b is b and the side length of side c is c. Their side length relationship is a:b:c=1:(0.2~0.35):(0.70~0.95). This ensures that the triangular connecting tilting platform 510 can provide reliable and stable support for the spiral sickle arch-breaking plate 520. It also ensures that the exposed area of ​​the second surface 511 and the third surface 512 of the triangular connecting tilting platform 510 is small to the greatest extent, so as to minimize the problem of material accumulation on the second surface 511 and the third surface 512 of the triangular connecting tilting platform 510.

[0060] In one embodiment, the triangular connecting tilting platform 510 protrudes at least partially from the rotating cylinder 200, which facilitates the spiral sickle arch-breaking plate 520 to better adhere to and scrape the powder from the inner wall of the funnel-shaped feeding end 110.

[0061] In one embodiment, the height of the rotating groove 513 is 1 to 3 times the length of the triangular connecting inclined platform 510, so that the distribution of the added rotating groove 513 on the triangular connecting inclined platform 510 is more suitable. While satisfying the flexibility of the rotation of the rotating cylinder 200 and the funnel-shaped feeding end 110, it also ensures that the triangular connecting inclined platform 510 can provide reliable and stable support for the spiral sickle arch-breaking plate 520.

[0062] In one embodiment, the rotating locking groove 230 is adapted to the funnel-shaped feeding end 110, so that when the funnel-shaped feeding end 110 is fitted into the rotating locking groove 230, the inner wall of the funnel-shaped feeding end 110 can be flush with the inner wall of the rotating cylinder 200. This effectively avoids the problem of material accumulation caused by unevenness between the funnel-shaped feeding end 110 and the rotating cylinder 200 after installation, thereby improving the utilization rate of powder materials. At the same time, it also maximizes the single discharge volume of powder materials to ensure rapid discharge of powder materials.

[0063] It is understandable that in practical applications, due to the structural characteristics of the triangular connecting inclined platform 510, material accumulation still exists on both sides of the rotating groove 513. Therefore, in one embodiment, the rotating groove 513 forms a first arc-shaped material-avoiding area on the second surface 511 of the triangular connecting inclined platform 510; the rotating groove 513 forms a second arc-shaped material-avoiding area on the third surface 512 of the triangular connecting inclined platform 510; effectively improving the phenomenon of powder material accumulation on both sides of the rotating groove 513, thereby improving the utilization rate of powder material.

[0064] In one embodiment, the spiral sickle arch-breaking plate 520 includes a spiral inclined scraping abutment portion 521 and a spiral inclined piercing portion 522; the spiral inclined piercing portion 522 is connected to the connecting inclined platform 510 through the spiral inclined scraping abutment portion 521. Since both the spiral inclined scraping abutment portion 521 and the spiral inclined piercing portion 522 have a spiral curved arch-breaking inclined sliding area, the spiral sickle arch-breaking plate 520 is bent and inclined, which is beneficial for arch breaking and material discharge. The spiral inclined piercing portion 522 is a free end, which allows it to effectively pierce the powder arch structure, thereby achieving a faster arch breaking effect.

[0065] In one embodiment, the arch-breaking inclined discharge channel 530 further includes a first spiral curved arch-breaking inclined sliding area 533 and a second spiral curved arch-breaking inclined sliding area 534 that are connected to each other; the spiral inclined scraping abutment part 521 forms the first spiral curved arch-breaking inclined sliding area 533, and the spiral inclined piercing part 522 forms the second spiral curved arch-breaking inclined sliding area 534. The first spiral curved arch-breaking inclined sliding area 533 is connected to the first arch-breaking inclined discharge sub-area 531 and the second arch-breaking inclined discharge sub-area 532 respectively, so as to jointly form the arch-breaking inclined discharge channel 530 to ensure that the powder after arch breaking can be discharged smoothly.

[0066] In one embodiment, the spiral inclined scraping contact part 521 is inclined towards the inner wall of the funnel-shaped feeding end 110, while the spiral inclined piercing part 522 is inclined away from the inner wall of the funnel-shaped feeding end 110. This allows the spiral inclined scraping contact part 521 to adhere well to and scrape away the powder from the inner wall of the funnel-shaped feeding end 110, while ensuring that the spiral inclined piercing part 522 does not easily collide with the inner wall of the funnel-shaped feeding end 110 when rotating to break the arch. On the one hand, this facilitates the spiral inclined piercing part 522 to better pierce the powder arch structure, achieving a faster arch-breaking effect; on the other hand, it reduces the wear between the spiral inclined piercing part 522 and the inner wall of the funnel-shaped feeding end 110, thereby improving the service life of the spiral sickle arch-breaking plate 520 and the funnel powder hopper 100.

[0067] It is worth mentioning that, since the spiral tilting direction of the spiral inclined piercing part 522 is set away from the inner wall of the funnel-shaped feeding end 110, the spiral sickle arch-breaking plate 520 is located on one side of the funnel-shaped feeding end 110. This ensures that the arch-breaking method of the spiral sickle arch-breaking plate 520 is eccentric arch-breaking. In this way, the spiral inclined piercing part 522 can not only pierce the powder arch structure more quickly to achieve a faster arch-breaking effect, but also further reduce the arch-breaking force of the spiral inclined piercing part 522, thereby reducing the probability of the spiral sickle arch-breaking plate 520 breaking. This is especially suitable for applications with viscous powder arch structures.

[0068] In one embodiment, the spiral tilting direction of the spiral tilting scraping abutment portion 521 is consistent with the tilting direction of the funnel-shaped feeding end 110, so as to ensure that the spiral tilting scraping abutment portion 521 can better adhere to and scrape off the powder on the inner wall of the funnel-shaped feeding end 110.

[0069] In one embodiment, the center point of the spiral of the spiral inclined piercing part 522 does not coincide with the center point of the funnel-shaped feeding end 110, so as to achieve the eccentric setting of the spiral inclined piercing part 522 at the funnel-shaped feeding end 110.

[0070] It is understandable that, due to the large breaking force required by the spiral sickle arch-breaking plate 520 when breaking an arch, coupled with its own structural characteristics, the spiral sickle arch-breaking plate 520 still faces the problem of breakage even after prolonged breaking of arched structures with a certain degree of viscosity. Therefore, in one embodiment, the width of the spiral inclined scraping abutment portion 521 gradually decreases from the end closer to the connecting inclined platform 510 to the end farther away from the connecting inclined platform 510, to ensure that the rigidity of the spiral inclined scraping abutment portion 521 is good, thereby improving the problem of the spiral sickle arch-breaking plate 520 easily breaking when breaking arched structures with a certain degree of viscosity for a long time.

[0071] Similarly, in one embodiment, the width of the spiral inclined piercing portion 522 gradually decreases from the end near the spiral inclined scraping abutment portion 521 to the end away from the spiral inclined scraping abutment portion 521, so as to ensure that the spiral inclined piercing portion 522 has good rigidity, that is, to ensure the structural strength of the spiral inclined piercing portion 522; further improving the problem that the spiral sickle arch-breaking plate 520 is prone to breakage when breaking an arch structure with a certain viscosity for a long time.

[0072] In one embodiment, the width of the spiral inclined scraping abutment portion 521 near the connecting inclined platform 510 is equal to the width of the connecting inclined platform 510 near the spiral inclined scraping abutment portion 521; the width of the spiral inclined piercing portion 522 near the spiral inclined scraping abutment portion 521 is equal to the width of the spiral inclined scraping abutment portion 521 near the spiral inclined piercing portion 522, especially in conjunction with the width of the spiral inclined scraping abutment portion 521 being equal to the width of the spiral inclined scraping abutment portion 521 near the connecting inclined platform 510. The spiral inclined piercing part 522 is used to gradually decrease in width from the end away from the connecting tilting table 510, and the width of the spiral inclined scraping abutment part 521 gradually decreases from the end near the spiral inclined scraping abutment part 521 to the end away from the spiral inclined scraping abutment part 521. This ensures that the connection between the spiral inclined piercing part 522 and the spiral inclined scraping abutment part 521 is relatively flat and smooth, and the connection between the connecting tilting table 510 and the spiral inclined scraping abutment part 521 is relatively flat and smooth, effectively avoiding the problem of easy material accumulation on the spiral sickle arch-breaking plate 520.

[0073] In one embodiment, the thickness of the spiral inclined scraping abutment portion 521 gradually decreases from the end near the connecting inclined platform 510 to the end away from the connecting inclined platform 510; this further ensures that the spiral inclined scraping abutment portion 521 has good structural strength, thereby ensuring the reliability and stability of the spiral sickle arch-breaking plate 520 when breaking the arch, and further avoiding the problem that the spiral inclined scraping abutment portion 521 is prone to breakage.

[0074] Similarly, in one embodiment, the thickness of the spiral inclined piercing portion 522 gradually decreases from the end near the spiral inclined scraping abutment portion 521 to the end away from the spiral inclined scraping abutment portion 521. This ensures, on the one hand, that the spiral inclined piercing portion 522 itself has a better structural structure, thereby ensuring the reliability and stability of the spiral inclined piercing portion 522 when breaking the arch, and further avoiding the problem that the spiral inclined piercing portion 522 is prone to breakage; on the other hand, it also ensures that the thickness of the piercing portion of the spiral inclined piercing portion 522 is smaller, which is more conducive to the spiral inclined piercing portion 522 piercing the viscous powder arch structure, especially the piercing of the more solid powder arch structure.

[0075] In one embodiment, the spiral inclined piercing portion 522 is retracted at one end away from the spiral inclined scraping abutment portion 521 to form a piercing needle, so that the spiral inclined piercing portion 522 pierces the powder arch structure.

[0076] In one embodiment, the connecting spiral inclined piercing part 522, the spiral inclined scraping abutment part 521 and the connecting inclined platform 510 are integrally formed to ensure the stability of the connection between the spiral sickle arch-breaking plate 520 and the connecting inclined platform 510, thereby improving the service life of the spiral sickle arch-breaking plate 520 and the connecting inclined platform 510.

[0077] In one embodiment, the tilting platform 510 and the rotating cylinder 200 are integrally formed to ensure the stability of the connection between the tilting platform 510 and the rotating cylinder 200.

[0078] In one embodiment, the fixing component 600 further includes a fixing seat 810. The first end of the fixing seat 810 is sleeved on the outer peripheral wall of the funnel-shaped feeding end 110 to achieve connection with the funnel-shaped feeding end 110. The first end of the fixing seat 810 is threadedly connected to the first fixing ring 610, realizing a detachable connection between the fixing seat 810 and the first fixing ring 610, which is convenient for the operator to disassemble and assemble the fixing seat 810. The second end of the fixing seat 810 is connected to the feeding end of the funnel receiving bin 300 to achieve a connection between the fixing seat 810 and the funnel receiving bin 300. In this way, the added fixing seat 810 can achieve better fixation of the rotating cylinder 200.

[0079] In one embodiment, the powder arch-breaking and feeding device 10 further includes a first bearing 820 and a second bearing 830. The first bearing 820 is disposed between the first fixing ring 610 and the first end of the rotating cylinder 200 to reduce wear between the first fixing ring 610 and the first end of the rotating cylinder 200. The second bearing 830 is disposed between the second fixing ring 620 and the second end of the rotating cylinder 200 to reduce wear between the second fixing ring 620 and the second end of the rotating cylinder 200.

[0080] Specifically, in one embodiment, the inner ring of the first bearing 820 is sleeved on the outer peripheral wall of the first end of the rotating cylinder 200; the first fixing ring 610 is sleeved on the outer ring of the first bearing 820; so as to realize the rotational setting of the first bearing 820 and the first fixing ring 610 at the first end of the rotating cylinder 200, effectively reducing the wear of the first fixing ring 610 and the first end of the rotating cylinder 200.

[0081] Similarly, in other embodiments, the inner ring of the second bearing 830 is sleeved on the outer peripheral wall of the second end of the rotating cylinder 200; the first fixing ring 620 is sleeved on the outer ring of the second bearing 830; so as to realize the rotational setting of the second bearing 830 and the second fixing ring 620 at the second end of the rotating cylinder 200, effectively reducing the wear of the second fixing ring 620 and the first end of the rotating cylinder 200.

[0082] In one embodiment, the powder arch-breaking and feeding device 10 further includes a first airbag sealing ring 840; the first airbag sealing ring 840 is disposed between the first fixed ring 610 and the first end of the rotating cylinder 200, and the first airbag sealing ring 840 is used to seal the first connection 210, effectively reducing the problem of powder leakage at the first connection 210.

[0083] And / or, in one embodiment, the powder arch-breaking and feeding device 10 further includes a second airbag sealing ring 850; the second airbag sealing ring 850 is disposed between the second fixed ring 620 and the second end of the rotating cylinder 200, and the second airbag sealing ring 850 is used to seal the second connection 220, effectively reducing the problem of powder leakage at the second connection 220.

[0084] In one embodiment, a first airbag sealing ring 840 is sleeved on the outer peripheral wall of the first connection 210, and a first fixing ring 610 is sleeved on the outer peripheral wall of the first airbag sealing ring 840 to achieve a seal on the first connection 210. Similarly, a second airbag sealing ring 850 is sleeved on the outer peripheral wall of the second connection 220, and a second fixing ring 620 is sleeved on the outer peripheral wall of the second airbag sealing ring 850 to achieve a seal on the second connection 220.

[0085] In one embodiment, the specific structures of the first airbag sealing ring 840 and the second airbag sealing ring 850 are prior art. Therefore, they will not be described in detail in this disclosure.

[0086] In one embodiment, the first airbag sealing ring 840 is fitted onto the first connection 210, the first bearing 820 is disposed below the first connection 210, and the first fixing ring 610 is formed with a cavity for accommodating the first airbag sealing ring 840 and the first bearing 820. In this way, while reducing the wear between the first fixing ring 610 and the first end of the rotating cylinder 200, the leakage of powder between the first fixing ring 610 and the first end of the rotating cylinder 200 is also reduced.

[0087] Similarly, in one embodiment, the second airbag sealing ring 850 is correspondingly sleeved on the second connection 220, the second bearing 830 is disposed above the second connection 220, and the second fixing ring 620 is correspondingly formed with a second receiving cavity. The second receiving cavity is used to receive the second airbag sealing ring 850 and the second bearing 830. In this way, while reducing the wear between the second fixing ring 620 and the second end of the rotating cylinder 200, the leakage of powder between the second fixing ring 620 and the second end of the rotating cylinder 200 is also reduced.

[0088] In one embodiment, the large gear 720 is located in the middle of the outer peripheral wall of the rotating cylinder 200 to ensure that the large gear 720 can reliably and smoothly drive the rotating cylinder 200 to rotate, thereby ensuring the reliability of the operation of the rotating cylinder 200 and effectively avoiding the problem that the spiral sickle arch-breaking plate 520 is prone to breakage due to the unstable operation of the rotating cylinder 200. Specifically, the outer peripheral wall of the rotating cylinder 200 is formed with a mounting groove 240, which accommodates the large gear 720.

[0089] In one embodiment, the outer peripheral wall of the rotating cylinder 200 is further formed with a first receiving groove 250 and a second receiving groove 260, which are located on both sides of the mounting groove 240, respectively. The first receiving groove 250 is used to accommodate the first bearing 820 and the first airbag sealing ring 840; the second receiving groove 260 is used to accommodate the second bearing 830 and the second airbag sealing ring 850, thereby improving the structural integrity of the connection between the rotating cylinder 200, the first bearing 820, the second bearing 830, the first airbag sealing ring 840, and the second airbag sealing ring 850.

[0090] Specifically, in one embodiment, the first airbag sealing ring 840 and the first bearing 820 are arranged sequentially from top to bottom in the first receiving groove 250; the second bearing 830 and the second airbag sealing ring 850 are arranged sequentially from top to bottom in the second receiving groove 260.

[0091] It should be noted that, in order to better satisfy the flexibility and sealing of the rotation of the rotating cylinder 200, in one embodiment, the funnel-shaped feeding end 110 is formed with a mounting protrusion. The first mounting protrusion is sleeved in the rotation locking groove 230 of the rotating cylinder 200. The first fixing ring 610 forms a first cavity and is sleeved on the first mounting protrusion, together with the first mounting protrusion forming a first rotating receiving cavity. The first airbag sealing ring 840 and the first bearing 840 are arranged sequentially from top to bottom in the first cavity to ensure the flexibility and sealing of the rotation of the rotating cylinder 200 and the first fixing ring 610; especially in conjunction with the funnel... The feeding end 310 of the receiving hopper has an installation groove. The rotating cylinder 200 is rotatably disposed in the installation groove. The second fixing ring 620 forms a second cavity and is sleeved on the outer peripheral wall of the installation groove, forming a second rotating receiving cavity together with the outer peripheral wall of the installation groove. The second bearing 830 and the second airbag sealing ring 850 are arranged sequentially from top to bottom in the second cavity to ensure the flexibility and sealing of the rotation of the rotating cylinder 200 and the second fixing ring 620. In this way, not only are the flexibility and sealing of the rotation of the rotating cylinder 200 well satisfied, but the compactness of the structure of the powder arch breaking and feeding device 10 is also improved.

[0092] In one embodiment, the powder breaking and feeding device 10 further includes a second driver 900; the feed end of the funnel receiving bin 300 has a feed inlet, and the rotating plate 410 of the valve body 400 is rotatably disposed within the funnel receiving bin 300; the rotating plate 410 is used to close the feed inlet, and the rotating plate 410 is connected to the driving end of the second driver 900, so that the second driver 900 can drive the rotating plate 410 to rotate, thereby opening or closing the feed inlet; the second driver 900 is disposed at the end of the feed end of the funnel receiving bin 300, thereby fixing the second driver 900.

[0093] In one embodiment, the first driver 710 and the second driver 900 can be a motor or a cylinder.

[0094] Compared with the prior art, the present invention has at least the following advantages:

[0095] 1. Since the funnel powder hopper 100, the rotating cylinder 200, and the funnel receiving hopper 300 are sequentially connected from top to bottom, the first end of the rotating cylinder 200 is rotatably disposed at the funnel-shaped discharge end 110 of the funnel powder hopper 100, and the second end of the rotating cylinder 200 is rotatably disposed at the inlet end of the funnel receiving hopper 300; this allows the rotating cylinder 200 to be located at the funnel-shaped discharge end 110 at the bottom of the funnel powder hopper 100, and the rotating cylinder 200 extends the discharge space of the funnel-shaped discharge end 110, which is beneficial for material discharge; furthermore, since one side of the connecting inclined platform 510 is disposed on the inner wall of the rotating cylinder 200, and one end of the connecting inclined platform 510 is connected to the inner wall of the funnel powder hopper 100, the rotating cylinder 200 is rotatably disposed at the funnel-shaped discharge end 110, which is beneficial for material discharge; and since one side of the connecting inclined platform 510 is disposed on the inner wall of the rotating cylinder 200, and one end of the connecting inclined platform 510 is connected to the inner wall of the funnel powder hopper 100, the rotating cylinder 200 is rotatably disposed at the funnel-shaped discharge end 110, which is rotatably disposed at the funnel-shaped discharge end 110, the rotating cylinder 20 ... The spiral sickle arch-breaking plate 520 connects the inclined platform 510, the spiral sickle arch-breaking plate 520, and the rotating cylinder 200 to form an arch-breaking inclined discharge channel 530. The spiral sickle arch-breaking plate 520 extends into the funnel-shaped discharge end 110 and moves against the inner wall of the funnel-shaped discharge end 110. In this way, by extending the spiral sickle arch-breaking plate 520 into the funnel-shaped discharge end 110, the internal space occupied by the funnel powder silo 100 is effectively reduced, thereby improving the space utilization rate of the funnel powder silo 100. In addition, the connection between the inclined platform 510 and the spiral sickle arch-breaking plate 520, which together form the arch-breaking inclined discharge channel 530, is beneficial to the discharge of material from the funnel powder silo 100.

[0096] 2. Compared with the traditional rotating ring, since the area of ​​the rotating cylinder 200 is larger than that of the rotating ring, the rotating cylinder 200 of this disclosure can provide reliable and stable structural support for the spiral sickle arch-breaking plate 520, effectively avoiding the phenomenon that the spiral sickle arch-breaking plate 520 is prone to breakage.

[0097] 3. Since one side of the connecting tilting platform 510 is located on the inner wall of the rotating cylinder 200, and one end of the connecting tilting platform 510 is connected to the spiral sickle arch-breaking plate 520, the spiral sickle arch-breaking plate 520 is located on one side of the rotating cylinder 200. This ensures that the spiral sickle breaks the arch in an eccentric manner, thereby reducing the arch-breaking force of the spiral tilting piercing part 522 and further reducing the probability of the spiral sickle arch-breaking plate 520 breaking.

[0098] 4. In practical applications, powder arching is prone to occur at the contraction point of the traditional funnel-shaped feeding end 110. Since most powder arching structures are upward, and the traditional air-jet scraper is located above the funnel-shaped feeding end 110, the air-jet scraper is located on the convex surface of the powder arching, resulting in a large arch-breaking force of the air-jet scraper and an increased probability of the air-jet scraper breaking. In addition, auxiliary components need to be added to assist its arch-breaking effect, making the traditional arch-breaking structure more complex. Therefore, in this disclosure, the rotating cylinder 200 is positioned below the funnel-shaped feeding end 110, so that the spiral sickle-shaped anti-arch plate 520 is positioned on the concave surface of the powder arch structure. This makes the force on the spiral sickle-shaped anti-arch plate 520 to pierce the concave surface relatively smaller than the force on the convex surface. In this way, the powder arch structure can be broken without the need for additional air conveying components. This not only simplifies the structure but also further reduces the probability of the spiral sickle-shaped anti-arch plate 520 breaking. It is especially suitable for applications with viscous powder arch structures.

[0099] 5. Since the first end of the rotating cylinder 200 is rotatably disposed at the funnel-shaped discharge end 110 of the funnel powder hopper 100 and forms a first connection 210; the second end of the rotating cylinder 200 is rotatably disposed at the feed end of the funnel receiving hopper 300 and forms a second connection 220, the rotating cylinder 200 is detachably disposed from the funnel-shaped discharge end 110 and the feed end of the funnel receiving hopper 300 respectively; and since the first fixing ring 610 is sleeved on the first connection 210 and the first fixing ring 610 is detachably connected to the funnel-shaped discharge end 110; and the second fixing ring 620 is sleeved on the second connection 220 and the second fixing ring 620 is detachably connected to the feed end of the funnel receiving hopper 300, the rotating cylinder 200 is detachably fixed, thereby facilitating the operator to disassemble and assemble the rotating cylinder 200 to replace a damaged rotating cylinder 200 or replace it with a suitable rotating cylinder 200.

[0100] The embodiments described above are merely illustrative of several implementations of the present invention, and while their descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
