A flow divider cone for powder filling

Abstract

This utility model discloses a diversion cone for powder filling, relating to the field of powder filling technology. The device includes a connecting pipe, a discharge pipe, and a cone. The connecting pipe connects to the discharge pipe at the bottom of the powder container. The discharge pipe is installed at the bottom of the connecting pipe, and at least a portion of the inner diameter of the discharge pipe gradually increases from top to bottom. The cone is disposed inside the discharge pipe. This diversion cone for powder filling provides ample diffusion space for the powder through the discharge pipe, which is narrower at the top and wider at the bottom. Combined with the internal cone, it forms a blocking and diversion mechanism, causing the powder to first impact the cone and be forcibly dispersed after flowing out of the connecting pipe, and then fall evenly along the gap between the cone and the discharge pipe. This avoids the local accumulation problem of traditional direct filling, and the powder can evenly cover the entire cross-section of the container, thereby achieving uniform mixing and filling of large, medium, and small particle sizes, avoiding stratification.

Description

Technical Field

[0001] This utility model relates to the field of powder filling technology, and in particular to a flow divider cone for powder filling. Background Technology

[0002] In many fields such as food processing, pharmaceutical manufacturing, and chemical production, quantitative filling of powders is a key step in the production process. Its filling quality directly affects the quality stability, packaging consistency, and subsequent production and processing efficiency of the final product.

[0003] Currently, the industry commonly uses powder tanks to store powders and then directly conveys them to powder receiving containers (such as packaging bags, barrels, molds, etc.) through a discharge pipe at the bottom of the tank for filling. However, in actual production, due to the physical properties of the powder itself (such as particle size differences, surface tension, and hygroscopicity) and the storage environment (such as temperature and humidity), the powder is prone to agglomeration in the powder tank, forming clumps of varying sizes. These agglomerated clumps are difficult to disperse naturally during the conveying process through the discharge pipe and tend to accumulate locally after entering the powder receiving container. This results in significant differences in powder density in different areas of the container, making it impossible to achieve uniform separation and distribution of large, medium, and small particle sizes during the filling process. Often, large-diameter powder settles at the bottom of the container while small-diameter powder floats on top. This uneven distribution in the mixing of raw materials in the chemical industry can lead to inconsistent reaction rates and affect product yield. Utility Model Content

[0004] This invention provides a flow divider cone for powder filling, which can solve the problem mentioned in the background art that agglomerated powder clumps are difficult to disperse naturally during the conveying process of the discharge pipe, often resulting in large-diameter powder particles settling at the bottom of the container and small-diameter powder particles floating at the top.

[0005] A flow divider cone for powder filling includes a connecting pipe, a discharge pipe, and a cone. The connecting pipe is used to connect with a discharge pipe at the bottom of a powder tank. The discharge pipe is installed at the bottom of the connecting pipe, and at least a portion of the inner diameter of the discharge pipe gradually increases from top to bottom. The cone is disposed inside the discharge pipe, and the outer periphery of the bottom of the cone is connected to the inner surface of the discharge pipe via a connecting rod.

[0006] Preferably, the number of connecting rods is three, and they are evenly distributed along the circumference of the cone.

[0007] Preferably, the vertical cross-section of the connecting rod is triangular, and one of the apex angles of the triangular vertical cross-section of the connecting rod faces the feeding direction of the feed pipe.

[0008] Preferably, the connecting rod 4 is disposed on the outer periphery of the bottom of the cone 3.

[0009] Preferably, the connecting pipe includes a first pipe body and a first mounting pipe disposed at the lower end of the first pipe body, the first mounting pipe having an internal thread, and the feeding pipe includes a second pipe body and a second mounting pipe disposed at the upper end of the second pipe body that is adapted to the first mounting pipe, the second mounting pipe having an external thread adapted to the internal thread.

[0010] Preferably, the cone is disposed inside the second tube, and the inner diameter of the second tube gradually increases from top to bottom.

[0011] Preferably, the inner diameter of the first mounting tube is larger than the inner diameter of the first tube body, and the inner diameter of the second mounting tube is the same as the inner diameter of the first tube body.

[0012] Preferably, the vertex angle of the triangle is 30°-60°.

[0013] Preferably, the cone angle of the cone is 30°-60°.

[0014] This utility model has at least the following beneficial effects: This powder filling device uses a diversion cone. For example, the inner diameter of the feed pipe gradually increases from top to bottom, meaning the feed pipe has a narrow top and wide bottom structure. This narrow top and wide bottom feed pipe provides ample space for powder diffusion. Combined with the internal cone, it forms a blocking and diversion mechanism, so that after the powder flows out of the connecting pipe, it first impacts the cone and is forcibly dispersed, and then falls evenly along the space between the cone surface and the inner surface of the feed pipe. This avoids the local accumulation problem of traditional direct filling. At the same time, the powder can evenly cover the entire cross-section of the container, thereby achieving uniform mixing and filling of large, medium and small particle sizes and avoiding stratification.

[0017] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0018] Example 1: like Figure 1-3 As shown, this utility model proposes a diverting cone for powder filling, including a connecting pipe 1, a feeding pipe 2, and a cone 3. The connecting pipe 1 is used to connect with the discharge pipe 6 at the bottom of the powder tank 5. The feeding pipe 2 is installed at the bottom of the connecting pipe 1, and the inner diameter of the feeding pipe 2 gradually increases from top to bottom. The cone 3 is disposed inside the feeding pipe 2, and the outer periphery of the bottom of the cone 3 is connected to the inner surface of the feeding pipe 2 through multiple connecting rods 4, which is used to break up clumps of powder.

[0019] In this embodiment, the connecting pipe 1 is directly adapted to the discharge pipe 6 at the bottom of the existing powder tank 5, eliminating the need to modify the original equipment and reducing the enterprise's upgrade costs. For example, the inner diameter of the discharge pipe 2 gradually increases from top to bottom, meaning the discharge pipe 2 has a narrow top and wide bottom structure. This narrow top and wide bottom discharge pipe 2 provides sufficient diffusion space for the powder. Combined with the internal cone 3, it forms a blocking and diversion mechanism, so that after the powder flows out of the connecting pipe 1, it first impacts the cone 3 and is forcibly dispersed, and then falls evenly along the space between the cone surface of the cone 2 and the inner surface of the discharge pipe 3. This avoids the local accumulation problem of traditional direct filling, and at the same time, it allows the powder of different particle sizes to be evenly dispersed and filled into the powder receiving container. The support design of multiple connecting rods 4 ensures that the cone 3 does not deviate under the impact of the powder, ensuring the stability of the diversion and laying a structural foundation for the subsequent uniform separation of particle sizes.

[0020] Specifically, the clumps of powder fall from the connecting pipe 1 and first directly impact the tip of the inner cone 3. This sudden impact provides the initial crushing force, breaking large clumps into smaller pieces. After impacting the cone 3, the powder flow is forced to change direction, from vertically downward to radially diverting outwards along the cone's inclined surface. During this process, the powder layer is thinned, and intense friction and shearing occur between powder pieces and between the powder and the cone surface, further breaking up the clumps. When the diverted powder flow passes through the triangular connecting rod 4, the sharp angle of the incoming flow cleaves the powder flow like a knife. This greatly enhances the shearing force on the powder, effectively tearing apart those tougher clumps that have not been broken up in the first two steps. The cleaved powder enters an annular channel with a gradually increasing cross-sectional area, formed by the cone surface and the inner wall of the discharge pipe 2. According to fluid dynamics principles (similar to the Venturi effect), the powder flow slows down in the diffused channel, but the probability of collisions between particles and between particles and the wall surface increases significantly. These continuous, multi-angle collisions thoroughly and uniformly disperse the powder particles. Ultimately, the completely dispersed powder of different particle sizes falls evenly and in a curtain-like manner from the annular outlet at the bottom of the feed pipe into the receiving container. Because the outlet is a complete ring rather than a point, the powder can evenly cover the entire cross-section of the container, thereby achieving uniform mixing and filling of large, medium, and small particle sizes and avoiding stratification.

[0021] The apex angle of the triangular vertical section of the connecting rod 4 is 30°-60°, the cone angle of the cone 3 is 30°-60°, and the connecting rod 4 is located on the outer periphery of the bottom of the cone 3.

[0022] like Figure 1 and Figure 3 As shown, there are three connecting rods 4, which are evenly distributed around the cone 3. The three evenly distributed connecting rods 4 (with an adjacent angle of 120°) form an optimal support structure. First, they have stronger mechanical stability and can balance the radial force of the cone 3 under the impact of powder, avoiding the diversion caused by the cone offset. Second, they form three uniform fan-shaped channels between the cone 3 and the feed pipe 2, and the powder can fall synchronously along the channels, avoiding local powder accumulation caused by the uneven width of the channels, further improving the uniformity of particle size distribution, and are especially suitable for medium and high flow rate filling scenarios.

[0023] like Figure 1 and Figure 3As shown, the vertical cross-section of the connecting rod 4 is triangular, with one sharp corner of the triangular vertical cross-section facing the feeding direction of the feed pipe 2. By having the sharp corner of the triangle facing the feeding direction, it can perform secondary cutting on the falling powder clumps like a "cutter". Combined with the initial dispersing by the cone 3, it further improves the powder dispersing efficiency, especially for highly viscous and easily agglomerated powders. At the same time, the side of the triangular cross-section can guide the powder to slide down quickly, avoiding powder residue on the surface of the connecting rod. It also reduces the friction area between the powder and the connecting rod, lowers the probability of static electricity generation, and prevents static electricity from aggravating powder agglomeration. It is suitable for food, medicine and other fields with high requirements for hygiene and anti-agglomeration.

[0024] like Figure 1 and Figure 3 As shown, the central axis of cone 3 coincides with the central axis of feed pipe 2. Coaxiality ensures uniform flow distribution. If the axes are misaligned, the gap between cone 3 and feed pipe 2 will be narrow on one side and wide on the other, causing powder to accumulate and fall from the wider gap, resulting in localized buildup. The coaxial design ensures that the gap width between cone 3 and feed pipe 2 is consistent around its perimeter, allowing for uniform powder distribution along the circumference. This avoids the problem of large-diameter powder accumulating on one side of the container while small-diameter powder floats on the other, ensuring consistent powder density and particle size distribution throughout the powder receiving container.

[0025] like Figure 1 and Figure 3 As shown, the connecting pipe 1, the feeding pipe 2, the cone 3 and the connecting rod 4 are integrally formed; the structure has strong integrity and no assembly seams, which can avoid powder residue at the seams, reduce cleaning difficulty, and at the same time prevent the cone from shifting due to loosening of the seams after long-term use, thus improving the service life of the equipment.

[0026] Example 2: like Figure 4 As shown, the connecting pipe 1 includes a first pipe body 101 and a first mounting pipe 102 at its lower end. The first mounting pipe 102 has an internal thread 103 inside. The feeding pipe 2 includes a second pipe body 201 and a second mounting pipe 202 at its upper end that is adapted to the first mounting pipe 102. The second mounting pipe 202 has an external thread 203 that is adapted to the internal thread 103 outside.

[0027] In this embodiment, the first mounting pipe 102 and the second mounting pipe 202 can be installed and disassembled through a threaded connection, and the connecting pipe 1 and the feeding pipe 2 can be installed and disassembled. This avoids the separation of the two due to the impact of powder during the filling process. The internal thread 103 can be used to adapt to the second mounting pipe 202 of different specifications (as long as the corresponding end of the feeding pipe has an external thread 203), which improves the adaptability of the equipment. Enterprises can replace the feeding pipe with a different taper according to the type of powder (such as coarse powder and fine powder) without replacing the entire diversion cone, thus reducing the equipment replacement cost. The threaded connection method does not require special tools, and operators can manually complete the disassembly and installation of the feeding pipe 2, which is convenient for regular cleaning and replacement of damaged parts, reducing maintenance difficulty and downtime.

[0028] Specifically, the inner diameter of the first mounting tube 102 is larger than the inner diameter of the first tube body 101, and the inner diameter of the second mounting tube 202 is the same as the inner diameter of the first tube body 101. The second mounting tube 202 is screwed into the first mounting tube 102, so that the first tube body 101 and the second tube body 201 are precisely connected, allowing the powder to smoothly transition from the first tube body 101 to the second tube body 201, and preventing the powder from getting stuck in the upper end of the feed tube 2 inside the connecting tube 1.

[0029] The cone 3 is located inside the second tube 201, and the inner diameter of the second tube 201 gradually increases from top to bottom.

[0030] Working principle: By directly adapting the connecting pipe to the discharge pipe 6 at the bottom of the existing powder tank 5, no modification to the original equipment is required, reducing the enterprise's upgrade costs. The discharge pipe 2, which is narrow at the top and wide at the bottom, provides sufficient diffusion space for the powder. Combined with the internal cone 3, it forms a blocking and diversion mechanism, so that after the powder flows out of the connecting pipe 1, it first impacts the cone 3 and is forcibly dispersed. Then, it falls evenly along the space between the cone surface of the cone 3 and the inner surface of the discharge pipe 2, avoiding the local accumulation problem of traditional direct filling. At the same time, it can evenly disperse the powder of different particle sizes and fill it into the powder receiving container. The support design of multiple connecting rods 4 ensures that the cone 3 does not deviate under the impact of the powder, ensuring the stability of the diversion and laying the structural foundation for the subsequent uniform separation of particle sizes.

[0031] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
