A powder dispensing dispenser

Abstract

This utility model discloses a powder dispensing device, comprising: a feeding device fixedly mounted on the upper end face of a bulk hopper; multiple discharge pipes disposed at the edge of the lower end face of the bulk hopper; a conical baffle plate disposed at the upper end of the inner end face of the bulk hopper; and an inner conical distributor, narrower at the top and wider at the bottom, disposed on the bottom end face of the bulk hopper to distribute powder into the multiple discharge pipes. A horizontally rotating dispensing device is mounted directly above the inner conical distributor via a longitudinal rotating column. The dispensing device disperses the powder entering through the feeding device, guides it through the baffle plate and the inner conical distributor, and simultaneously discharges it through the multiple discharge pipes. This application incorporates a rotating dispensing device within the powder flow channel. The high shear force of the dispensing device shears the material during the flow process, reducing the probability of bridging and clumping between powder particles, and improving the quality of the packaged product.

Description

Technical Field

[0001] This utility model relates to the field of powder packaging technology, specifically to a powder packaging dispenser. Background Technology

[0002] When dispensing corn starch from storage tanks, factors such as mutual adsorption, electrostatic force, and friction between powder particles cause obstruction or adhesion during flow—such as bridging and clumping. This obstructs the flow of material in the silo or conveying pipeline, reducing production continuity and efficiency. In particular, it significantly affects the quality of the dispensed products during the dispensing process. Furthermore, the clumping of powder particles increases the impact force on the conveying pipeline during flow, leading to accelerated equipment wear and even damage, increasing maintenance costs and downtime.

[0003] Most distributors currently on the market rely entirely on the weight of the powder itself, using a fixed dispensing cone for distribution. This can easily lead to blockages for powders that have bridging or caking. Although patent CN114132569A, entitled "Anti-clogging Uniform Dispenser," describes a vibrating rod on the baffle at the bottom of the storage hopper to prevent material from clogging the pipes during flow, caking powder is still directly dispensed into bags, affecting the quality of the bagged powder product. Utility Model Content

[0004] In view of the above-mentioned defects or deficiencies in the prior art, it is desirable to provide a powder dispensing device.

[0005] According to the technical solution provided in the embodiments of this application, a powder dispensing device includes a bulk hopper, a feeding device fixedly provided on the upper end face of the bulk hopper, and multiple discharge pipes provided on the edge of the lower end face of the bulk hopper; a conical baffle is provided on the upper end of the inner end face of the bulk hopper, and an inner conical distributor with a narrow upper part and a wide lower part is provided on the bottom end face of the bulk hopper for dispensing powder into multiple discharge pipes; a dispensing device that rotates in the horizontal direction is provided directly above the inner conical distributor via a longitudinal rotating column; the dispensing device disperses the powder entering through the feeding device, and then, guided by the baffle and the inner conical distributor, flows out through multiple discharge pipes.

[0006] Furthermore, the feeding device includes an inner feeding pipe and an outer feeding pipe. The upper end of the inner feeding pipe is fixedly passed through the upper end face of the outer feeding pipe. The inner feeding pipe is located directly above the material distribution device, which facilitates the material to fall directly onto the material distribution device.

[0007] Furthermore, the bulk material hopper is a cone shape that is narrower at the top and wider at the bottom, and the upper end face of the bulk material hopper is fixedly connected to the feed pipe.

[0008] Furthermore, a rotary motor is installed inside the inner conical distributor. The motor shaft of the rotary motor is fixedly connected to a rotating column. The upper part of the rotating column rotates through the inner conical distributor, realizing the rotation of the bulk material device in the horizontal direction.

[0009] Furthermore, the material dispersing device is a conical structure composed of multiple material dispersing blades, which facilitates the dispersal of materials and achieves uniform material distribution.

[0010] Furthermore, the baffle plate is a cone shape that is wider at the top and narrower at the bottom, and a vibration device is fixedly installed on the outer end face of the baffle plate to prevent powder from sticking to the inner wall of the baffle plate.

[0011] In summary, the beneficial effects of this application are as follows: This application has the following advantages: 1. This application is equipped with multiple discharge ports, which enables the material in the storage tank to be discharged from multiple discharge ports at the same time and to be packaged simultaneously, thereby improving the packaging efficiency; 2. This application provides a baffle plate inside the bulk hopper, which ensures that the powder flows in a concentrated manner to the bulking device. A vibration device is installed on the baffle plate to reduce the probability of material sticking to the wall, improve the flowability of the material, and prevent blockage. 3. This application sets up a rotating dispersing device in the powder flow channel. The high shear force of the dispersing device shears the material in the flow process, reducing the probability of bridging and clumping between powders and improving the quality of the packaged products.

[0014] The present application will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, only the parts relevant to the invention are shown in the accompanying drawings.

[0015] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other. This application will now be described in detail with reference to the accompanying drawings and embodiments.

[0016] A powder dispensing dispenser, such as Figure 1 and Figure 2 As shown, a feeding device 2 is fixedly installed on the upper end face of a cone-shaped bulk hopper 1 that is narrow at the top and wide at the bottom, and multiple discharge pipes 3 are installed on the edge of the lower end face. like Figure 2 As shown, the feeding device 2 includes an inner feeding pipe 21 and an outer feeding pipe 22. The upper end of the inner feeding pipe 21 is fixedly passed through the upper end face of the outer feeding pipe 22. The upper end face of the inner feeding pipe 21 is provided with a connecting flange. The lower end of the inner feeding pipe 21 is located inside the outer feeding pipe 22. like Figure 2 As shown, the bulk material hopper 1 is equipped with a baffle plate 4, an inner conical distributor 5, and a material dispersing device 7. The baffle plate 4 is a conical plate that is wider at the top and narrower at the bottom, and is fixed to the upper part of the bulk material hopper 1. The inner conical distributor 5 is a cone that is narrower at the top and wider at the bottom, and is fixed to the bottom surface of the bulk material hopper 1. A rotary motor 8 is installed inside the inner conical distributor 5. The motor shaft of the rotary motor 8 is fixedly connected to a rotating column 6. The rotating column 6 rotates through the upper surface of the inner conical distributor 5 and is then fixedly connected to the material dispersing device 7. Figure 4 The material handling device 7 is a conical structure composed of multiple material handling blades, and the material handling device 7 is located inside the baffle plate 4. like Figure 3 As shown, a ring-shaped support plate A is fixedly connected to the lower end face of the baffle plate 4. On the one hand, it fixes the baffle plate 4, making the connection of the baffle plate 4 more stable. On the other hand, it forms a closed space between the outer wall of the baffle plate 4 and the inner wall of the bulk hopper 1, which facilitates the installation of the vibration device 9 and can also prevent the vibration device 9 from being affected by powdery materials. The inner circle of the support plate A can perfectly fit the outer end face of the lower part of the baffle plate 4 to prevent material accumulation. Multiple vibration devices 9 are installed on the outer wall of the baffle plate 4 to prevent the accumulation of powdery materials on the baffle plate 4; like Figure 2 As shown, the center lines of the inner feed pipe 21, the outer feed pipe 22, the baffle plate 4, the inner cone distributor 5, the rotating column 6, and the dispersing device 7 are all located on the same vertical line.

[0017] Before use, connect the discharge port of the storage tank through the connecting device on the inner feed tube 21 of the feeding device 2, and then start the vibration device 9 and the rotary motor 8 through the control device. After the vibration device 9 is started, it acts on the baffle plate 4. After the rotary motor 8 is started, it acts on the dispersing device 7 through the rotating column 6, so that the dispersing device 7 rotates in the horizontal direction. Then, the outlet of the storage tank is opened, allowing the powdered material to fall. As the powdered material falls from the inner feed pipe 21, it falls directly onto the dispersing device 7 due to gravity. Since the dispersing device 7 is conical, the material is first evenly distributed through its conical structure. Then, through the shearing action of the rotating dispersing device 7, some clumps of material will be broken up, and some may even bounce onto the baffle plate 4. Due to the vibration device 9 installed on the outer wall of the baffle plate 4, the material will not accumulate on the baffle plate 4. Since the baffle plate 4 is conical, i.e., its inner wall is inclined, the material falls directly onto the inner conical distributor 5. The material will be evenly distributed into the discharge pipe 3 below the bulk hopper 1 by the inner conical distributor 5 for discharge.

[0018] Multiple discharge pipes 3 form a circle, with adjacent discharge pipes 3 abutting each other, and the inner wall of the discharge pipes 3 is a downward sloping ramp, such as... Figure 2 As shown, to more intuitively illustrate the inclination of the inner wall of the feed tube 3, Figure 2 Only the left and right discharge pipes 3 are displayed.

[0019] The vibration device 9 can be a vibration motor or a high-frequency vibration wave. It uses an ultrasonic generator to emit a high-frequency signal, which is then converted into mechanical vibration by a transducer.

[0020] The above description is merely a preferred embodiment of this application and an explanation of the technical principles and solutions employed. Furthermore, the scope of the invention involved in this application is not limited to technical solutions formed by specific combinations of the above-described technical features, but should also cover other technical solutions formed by arbitrary combinations of the above-described technical features or their equivalents without departing from the inventive concept. For example, technical solutions formed by substituting the above-described features with (but not limited to) technical features with similar functions disclosed in this application.
