Description

Technical Field

[0001] This utility model relates to the field of block-forming system technology, specifically to a mechanical block-forming system for powdered silica. Background Technology

[0002] Silica, due to its small particle size, large specific surface area, strong surface adsorption capacity, and stable chemical properties, plays an irreplaceable role in many chemical fields due to its superior stability, reinforcing properties, thickening properties, and thixotropic properties. It can be used to manufacture quartz glass, chemical containers, ordinary glass, refractory plastics, optical fibers, ceramics, etc., and can also be used as an additive in rubber, plastics, coatings, and even food and pharmaceuticals. In particular, adding silica to plastics makes them denser, improving not only transparency, strength, and flexibility, but also significantly enhancing waterproof and anti-aging properties.

[0003] When dry extrusion briquetting products, traditional technology suffers from low pre-degassing capacity, resulting in low briquetting output, poor dispersion, and high power consumption. The feed screw wears out quickly, with an average lifespan of only 50-60 days, leading to high maintenance workload and costs.

[0004] Existing technology discloses a patent with publication number CN206718584U. This solution includes a fine powder hopper, connected to a degassing and extrusion component, which is connected to a feeder. The feeder is connected to an extrusion block-forming machine. The degassing and extrusion component includes at least two interconnected augers, each auger connected to a vacuum degassing component. The pitch of the augers closer to the feeder is smaller. In this system, the material blocks processed by the multi-stage augers have a material density that is more than 50% higher than that produced by traditional technology. The feeding auger further increases the density of the material blocks by more than 15%, and ensures smooth discharge.

[0005] The shortcomings of existing technology have gradually become apparent with use, mainly in the following aspects:

[0006] First, the original silica powder silo had a volume of 500m³, which could store 130 tons of powder products. However, less than 40% of the product was actually utilized. The volume was too large, resulting in low effective utilization. Furthermore, a granulation unit was installed below the silo to clump the silica powder. Each unit could only clump one type of product, leading to a limited product range.

[0007] Secondly, the granulation unit has poor degassing properties, which cannot effectively reduce the gas content in the silica powder, causing gas resistance and affecting the material flowability and molding performance.

[0008] In conclusion, the existing technology obviously has inconveniences and defects in practical use, so it is necessary to improve it. Utility Model Content

[0009] To address the shortcomings of existing technologies, this utility model provides a mechanical agglomeration system for powdered silica. This system solves the problems of excessively large silica powder silos, low utilization rates, and the use of granulation units installed below the silos to agglomerate silica powder, resulting in limited product variety as each unit can only process one type of product. Furthermore, the granulation units have poor degassing capabilities, failing to effectively reduce the gas content in the silica powder, causing gas resistance, and affecting material flowability and molding performance.

[0010] To achieve the above objectives, this utility model provides the following technical solution:

[0011] A mechanical agglomeration system for powdered silica includes a powder silo, which is divided into two cavities by a vertically arranged partition. The discharge end of each cavity is connected to a granulation module via a pre-degassing machine. The discharge ends of the granulation modules are connected to a converging belt conveyor. The discharge end of the converging belt conveyor is connected to a feeding belt conveyor. The discharge end of the feeding belt conveyor is connected to a vertically arranged elevator. The discharge end of the elevator is connected to a block silo.

[0012] As an optimized solution, the granulation module includes a feed hopper connected to the pre-degassing machine, the feed hopper being connected to a granulator, and the granulation outlet end of the granulator being connected to the consolidation belt conveyor.

[0013] As an optimized solution, the pellet outlet end of the pellet mill is connected to a pellet shaping machine, and the outlet end of the pellet shaping machine is connected to the summing belt conveyor.

[0014] As an optimized solution, the powder outlet of the granulator is connected to an organic under-powder screening machine, and the outlet of the under-powder screening machine is connected to the secondary feed port of the feed hopper via a powder conveying pump.

[0015] As an optimized solution, the discharge port of the powder silo is connected to the pre-degassing machine via a rotary discharge valve.

[0016] As an optimized solution, the discharge port of the rotary discharge valve is connected to a metal dust collector, which is connected to the inlet of the pre-degassing machine.

[0017] As an optimized solution, a vibrating screen is connected between the summing belt conveyor and the feeding belt conveyor, and the powder outlet end of the vibrating screen is connected to a powder conveying pump.

[0018] As an optimized solution, the outlet end of the block silo is connected to a block packaging machine.

[0019] As an optimized solution, the lower end of the powder silo is provided with a hopper, the lower end of the partition extends into the hopper, and a three-way discharge valve is fixedly connected to each cavity on the side wall of the hopper near the lower end, and one of the discharge ports of the three-way discharge valve is connected to the rotary discharge valve.

[0020] As an optimized solution, another outlet of the three-way discharge valve is connected to a powder packaging machine.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The silica powder silo is divided in the middle by a partition, making it a dual-purpose silo that can store two different types of silica powder at the same time. This effectively utilizes the silica product silo and solves the problem of storage waste. The silo allows for separate use of the two silos, enabling users to freely choose whether to package or clump the material to meet different application needs. It also allows for seamless switching between different product types.

[0023] Two granulation modules are installed below the compartment. The front end of each granulation module is connected to a pre-degassing machine to achieve adjustable degassing degree. This can quickly and effectively reduce the gas content in silica powder and prevent gas blockage. Furthermore, the material density is more uniform after degassing, which improves material flowability and molding performance.

[0024] A pellet shaping machine is installed below the pelletizing module. By adjusting the shaping force of the pellet shaping machine, the size of the pellets can be precisely controlled to ensure stable pellet quality and meet the needs of different customers.

[0025] After being screened by both the powder screening machine and the vibrating screen, the powdered product is returned to the powder silo by the powder conveying pump, which separates the lumpy and powdered products and effectively controls the powder content of the lumpy product.

[0026] After briquetting, the material is conveyed to the briquetting silo by an elevator, and then packaged by a packaging machine;

[0027] A powder packaging machine can be installed below the hopper using a three-way valve body, which can package powdered silica products. Attached Figure Description
