Description

Technical Field

[0001] This utility model relates to the technical field of powder batching devices, specifically a multi-stage homogenization powder batching buffer silo structure. Background Technology

[0002] Powder batching systems are widely used in material mixing systems in chemical, construction, and food processing industries. They are mainly used for mixing and homogenizing powders. Currently, buffer silos are a commonly used container in mixing systems. Buffer silos are mainly used for buffering and transferring materials. Their core function is to solve the rhythm differences between upstream and downstream equipment and avoid material interruption or overflow. However, current buffer silos do not homogenize the incoming materials, which means that the materials need to be fully mixed by a mixer during the batching process. This results in a longer mixing time and increased working pressure on the mixer. In view of this, this case was developed through in-depth research on the above problems. Utility Model Content

[0012] Beneficial effects

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3This utility model provides an implementation scheme: the current buffer silo does not have a homogenization effect on the incoming materials, and usually only has a buffering effect, which means that the materials need to be fully mixed by a mixer during the batching process, resulting in a long mixing time and increased working pressure of the mixer.

[0020] To address the aforementioned problems, this application discloses a multi-stage homogenization powder batching buffer silo structure, comprising a buffer silo body 1 as the main structure. The buffer silo body 1 is stably mounted on the ground by a buffer support. The buffer silo body 1 is a rectangular hollow shell, with a conical hopper extending integrally from its bottom end to facilitate powder aggregation and smooth discharge. A discharge port 3 is provided at the bottom end of the hopper, and a discharge gate for controlling the discharge is provided on the discharge port 3. A feed pipe 2 is provided at the top of the buffer silo body 1 to receive upstream powder. The buffer silo body 1 contains a key multi-stage homogenization structure, which achieves preliminary mixing during the material buffering process, significantly reducing the burden on the downstream mixer.

[0021] According to the instruction manual Figure 1-3 It can be seen that the above-mentioned multi-stage homogenization structure includes multiple fixed brackets 4 installed outside the buffer chamber 1. The fixed brackets 4 are equipped with power components 5 that provide power. The homogenization stirring rod 6 is fitted with a homogenization stirrer 7 that performs the homogenization and mixing function. The homogenization stirrer 7 is preferably a double spiral auger structure. Its powerful stirring ability can effectively break up powder agglomerates and promote the mixing of different components. A bushing is provided in the middle of the homogenization stirrer 7. The bushing is fixedly connected to the homogenization stirring rod 6 by bolts to ensure effective power transmission and facilitate disassembly and maintenance.

[0022] According to the instruction manual Figure 1-3 It is known that the above-mentioned multi-stage homogenization structure also includes several guide plates 8 for distributing and guiding the powder. The guide plates 8 are arranged on one side of the homogenizing agitator 7, designed as a sloping structure and their edges are not connected to the inner wall of the buffer chamber 1, forming a channel for the material to fall freely. Several homogenizing agitators 7 and several guide plates 8 are arranged alternately in the height direction in the buffer chamber 1 to form a multi-stage processing unit. During operation, the powder enters the buffer chamber 1 through the top feed pipe 2 and first falls on the uppermost sloping guide plate 8. After the powder stays briefly on the surface of the guide plate 8, it falls freely from the bottom edge of the slope to the corresponding homogenizing agitator 7 below it. The homogenizing agitator 7 (double spiral auger) rotates under power drive, performing strong shearing, lifting and scattering of the powder to achieve preliminary dispersing and mixing.

[0023] According to the instruction manual Figure 1-3As can be seen, the powder after the initial mixing continues to fall and encounters the guide plate 8 of the next layer. The guide plate 8 once again concentrates the powder and guides it to the bottom edge of the slope, causing it to fall onto the corresponding homogenizing agitator 7 of the next layer, forcing the material to redistribute. The above-mentioned process of guiding, dispersing and mixing is repeated between the alternately arranged guide plates 8 and homogenizing agitators 7. Each time the material flows through a homogenizing agitator 7, it is subjected to a mixing action. Different component powders are repeatedly cross-mixed under the strong action of the spiral auger. After multiple stages (usually at least two stages) of such treatment, the uniformity of the powder has been significantly improved in the buffer chamber.

[0024] Finally, the powder, after being homogenized in multiple stages, falls into the conical hopper at the bottom of the buffer silo for temporary storage and buffering. The highest point of the material level in the buffer silo 1 is set below the bottom homogenizing agitator 7 through the feeding control, ensuring that all powder can flow through at least one homogenizing agitator 7 for processing before being discharged. When batching is required, the discharge gate is opened, and the homogenized powder can be smoothly discharged into the subsequent process. Since the material has been fully pre-homogenized in the buffer silo, the working time required by the downstream mixer can be greatly shortened, and the working pressure is significantly reduced.

[0025] As a preferred option, the conical hopper design at the bottom of the buffer chamber 1 further prevents material bridging and ensures smooth material discharge.

[0026] As a preferred option, the homogenizing mixer 7 further employs a double-spiral auger structure, providing efficient axial and radial mixing capabilities.

[0027] As a preferred option, the homogenizing mixer 7 and the homogenizing mixing rod 6 are fixed by a bushing and bolts, which ensures a reliable connection and facilitates disassembly and assembly.

[0028] As a preferred embodiment, the power assembly 5 further includes a power motor 51, which is mounted on a fixed bracket 4. The drive end of the power motor 51 is connected to an output shaft 52. A shaft seat 53 is mounted on the fixed bracket 4 to cooperate with the output shaft 52 to provide rotational support. The fixed bracket 4 provides stable support. The power motor 51 drives the homogenizing stirring rod 6 and the stirrer to rotate via the output shaft 52. The output shaft 52 is connected to the homogenizing stirring rod 6, which extends into the buffer chamber 1, to transmit power.

[0029] As a preferred option, the guide plate 8 and the homogenizing agitator 7 are arranged alternately to form a material processing path in stages.

[0030] In summary, this multi-stage homogenizing powder batching buffer silo structure achieves redistribution by forcibly altering the material's falling path through the guide plate 8. Combined with a multi-stage high-powered agitator, it enables continuous and progressive mixing during the material buffering process, giving the buffer silo a highly efficient homogenization function. This fundamentally solves the problems of traditional buffer silos that only serve a storage function and have poor material uniformity, effectively shortening subsequent mixing time and reducing mixer energy consumption and wear.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
