Description

Technical Field

[0001] This utility model relates to solid powder mixing and storage technology, specifically a solid powder mixing silo. Background Technology

[0002] In the production and use of solid powders, multiple powders are usually placed in a mixing silo and mixed in proportion to obtain the desired mixed powder.

[0003] For example, the publication (announcement) number: CN222305598U, publication (announcement) date: 2025-01-07, discloses a feed mixing device that can reduce mixing time, including: a device body, a crushing chamber and a top cover mechanism. The device body has a mixing drum for mixing feed at the center. Compared with the prior art, this utility model feeds raw materials in different states into different feed pipes. Large particles or large solid structures of raw materials are fed into different crushing chambers for simultaneous processing. The crushing roller crushes them and then introduces them into the mixing drum through the feed pipe. Liquid or powdered raw materials are introduced into the mixing drum through the feed port and feed pipe. The mixing motor is started to drive the mixing frame to perform the mixing operation, thereby reducing the mixing time.

[0004] The shortcomings of existing technology are that, because multiple stirring rods are used when mixing multiple powders, the increased number of stirring rods increases frictional resistance and the burden on the motor, leading to increased damage to components and equipment. Furthermore, when the mixing hopper is emptied and multiple powders need to be mixed again, the powders initially added to the bottom of the hopper often pile up. Only after the hopper has accumulated to a certain volume do the multiple stirring rods begin to stir, resulting in incomplete mixing of the powder piled at the bottom, and the stirring rods failing to effectively agitate the powder at the bottom even after they have started working. Utility Model Content

[0005] The purpose of this invention is to provide a solid powder mixing hopper to address the aforementioned shortcomings in the prior art.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A solid powder mixing silo includes a silo and a rotating shaft that rotates around the axis of the silo, wherein an auger plate is fixedly mounted on the rotating shaft;

[0008] It also includes blades arranged circumferentially on the shaft;

[0009] The hopper is fixedly equipped with a hopper cover, and the hopper cover has multiple material inlets that cooperate with the blade conveyor.

[0010] As a further description of the above technical solution: it also includes a conveying cylinder located outside the auger blades.

[0011] As a further description of the above technical solution: multiple support rods are fixedly installed between the conveying cylinder and the bottom of the hopper.

[0012] As a further description of the above technical solution: a connecting arm is fixedly installed between the blade and the rotating shaft.

[0013] As a further description of the above technical solution: the blade slides against the upper port of the conveying cylinder and maintains a predetermined included angle.

[0014] As a further description of the above technical solution: the blade has an arc surface.

[0015] As a further description of the above technical solution: an arc plate that matches the arc surface is fixedly installed on the blade.

[0016] As a further description of the above technical solution: a gear located outside the hopper is fixedly installed at the end of the rotating shaft.

[0017] As a further description of the above technical solution: the auger plate is specifically a stainless steel metal plate.

[0018] As a further description of the above technical solution: the blade is specifically a metal plate.

[0019] In the above technical solution, the solid powder mixing bin provided by this utility model has the following beneficial effects: by allowing the raw material powder to fall naturally under gravity, multiple powders can be naturally floated and mixed. With the addition of a rotating blade located on the initial path of the powder falling, the powder is dispersed, thereby enhancing the floating and mixing of powders in the bin and increasing the contact area for mixing multiple powders. This results in a significant improvement over traditional stirring and mixing in the initial stage and throughout the entire mixing process. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] Please see Figure 1-4 This utility model provides a technical solution, including the following embodiments:

[0029] Example 1

[0030] Combination Figure 1 , Figure 2 and Figure 4 This embodiment provides a powder dispersing device during the powder falling process. The raw material powder falls naturally by gravity through the inlet on the hopper cover 11, allowing multiple powders to float and mix naturally. The device is equipped with a rotating blade 33 located on the initial path of the powder falling to disperse the powder, thereby enhancing the powder's floating and mixing within the hopper 1 and increasing the contact area for mixing multiple powders. This results in a significant improvement over traditional stirring and mixing in the initial stage and throughout the entire process, while also minimizing the impact on the wear and tear of components and equipment.

[0031] Specifically, the silo cover 11 is detachably installed on the upper port of the silo 1 using bolts and nuts, and the blade 33 made of hard metal has excellent pressure resistance and wear resistance. The welded connecting arm 32 ensures the stable support connection required for the blade 33, enabling the equipment to operate stably for a long time.

[0032] Example 2

[0033] This embodiment describes in detail how the mixed powder is recycled and mixed again. Specifically, the powder is lifted by the conveyor cylinder 2 located outside the auger plate 31 and then falls from the upper end of the conveyor cylinder 2, so that the powder is continuously stirred up and mixed, thereby achieving secondary mixing in the mixing process and further enhancing the mixing effect.

[0034] Specifically, the support rod 21 is integrally formed at the lower end of the conveying cylinder 2, and the gap between adjacent support rods 21 provides a space for the bottom of the hopper 1 to be drawn in. The support rod 21 is welded to the bottom of the hopper 1, and the bottom is also connected to a pipe for discharging material.

[0035] Example 3

[0036] Combination Figure 3 As shown in the figure, this embodiment describes the structure of the blade 33 in detail. The inclined blade 33 provides a boosting force to the falling powder, causing the powder to be subjected to a larger impact area and the dispersing efficiency is enhanced. The arc surface 34 is located on the impact area, which can further increase the contact area on the one hand, and on the other hand, it can scoop up the powder accumulated at the upper end of the conveying cylinder 2 and mix it with the falling powder to achieve three-stage mixing, which greatly improves the mixing effect.

[0037] Secondly, the arc plate 35 also enhances the ability of the arc surface 34. At the same time, when the rotation speed of the shaft 3 increases, the powder that detaches from the upper end of the arc plate 35 has an upward inertia along the arc, causing the powder to collide with the falling powder, and the mixing effect reaches its maximum.

[0038] Example 4

[0039] This embodiment provides a drive source for the rotating shaft 3, namely, using a motor output end connected to a ring gear, and making the ring gear mesh with the gear 4 to achieve rotational drive, which facilitates the adjustment of the rotational speed of the rotating shaft 3.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
