Description

Technical Field

[0001] This utility model relates to the field of twin-helix conveyors, and in particular to a calcium carbonate feeder equipped with a twin-helix pushing component. Background Technology

[0002] Ultrafine heavy calcium carbonate is a powder material produced from natural limestone through mechanical crushing, grading, and surface modification. Its particle size typically ranges from 2 to 10 μm, and it features a narrow particle size distribution, high whiteness, and low oil absorption. As an important inorganic filler, it is widely used in various industrial fields such as plastics, coatings, papermaking, rubber, and adhesives. In the plastics industry, ultrafine heavy calcium carbonate can significantly improve the rigidity, dimensional stability, and surface gloss of products; in the papermaking industry, it can improve the opacity, smoothness, and printability of paper; and in the coatings industry, it can enhance the hiding power and weather resistance of coatings. Due to these excellent performance characteristics, ultrafine heavy calcium carbonate occupies an irreplaceable position in modern industrial production, and its stable and efficient conveying process is crucial to ensuring product quality and production efficiency. During the production process, ultrafine heavy calcium carbonate needs to be conveyed by a feeder to ensure continuous and stable supply.

[0003] However, because calcium carbonate granules are prone to absorbing moisture and clumping, the clumps can easily clog the spiral pushing component of the twin-screw conveyor during transport, leading to reduced equipment efficiency and even shutdowns. Furthermore, the feeding of calcium carbonate into the twin-screw conveyor generates a large amount of dust, which not only pollutes the working environment but may also harm the health of operators. Therefore, this application proposes a calcium carbonate feeder equipped with a twin-screw pushing component to solve the above problems. Utility Model Content

[0020] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0021] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a calcium carbonate feeder equipped with a double-helix pushing component includes a double-helix conveyor body 1. A feed hopper 2 is fixedly installed at the upper end of the double-helix conveyor body 1. A crushing structure 3 is installed on the feed hopper 2. The crushing structure 3 consists of a reduction motor 9, a first rotating shaft 10, a second rotating shaft 11, crushing blades 12, and transmission gears 13. The first rotating shaft 10 and the second rotating shaft 11 are both rotatably installed inside the feed hopper 2. The reduction motor 9 is fixedly installed at one end of the first rotating shaft 10. There are several crushing blades 12, which are respectively fixedly sleeved on the first rotating shaft 10 and the second rotating shaft 11. There are two transmission gears 13, which are respectively fixedly installed at one end of the first rotating shaft 10 and the second rotating shaft 11, and the two transmission gears 13 mesh with each other. A dust removal component 4 is fixedly installed on the feed hopper 2 and above the crushing structure 3. The dust removal component 4 consists of a connecting base pipe 14, a connecting pipe 15, a dust suction pipe 16, and a protective net 18. The connecting pipe 15 and the dust suction pipe 16 are both fixedly installed on the feed hopper 2. A protective net 18 is fixedly installed on the dust suction pipe 16 on the connecting base pipe 14. A drive assembly 5 is installed on one side of the double helix conveyor body 1. The drive assembly 5 is connected to the double helix auger inside the double helix conveyor body 1. The feed hopper 2 consists of a discharge pipe 6 and a conical pipe 7. The conical pipe 7 is fixedly installed at the upper end of the discharge pipe 6. The discharge pipe 6 is fixedly installed at the upper end of the double helix conveyor body 1. A shaft hole is opened on the discharge pipe 6 on the feed hopper 2. An installation insertion hole 8 is opened on the conical pipe 7 on the conical pipe 7. When conveying calcium carbonate material, the calcium carbonate material is first poured into the conical pipe 7 of the feed hopper 2. At the same time, the reduction motor 9 is started. The reduction motor 9 drives the first rotating shaft 10 to rotate. The first rotating shaft 10 drives the second rotating shaft 11 to rotate in the opposite direction through the transmission gear 13. The crushing blade 12, which is fixedly sleeved on the first rotating shaft 10 and the second rotating shaft 11, rotates accordingly to crush the calcium carbonate material entering the discharge pipe 6, effectively decompose the agglomerates, and prevent blockage of the double helix auger inside the double helix conveyor body 1. The crushed material enters the main body 1 of the twin-screw conveyor through the feed pipe 6. The drive assembly 5 drives the twin-screw conveyor to continuously and stably transport the material to the designated location. Simultaneously, a dust collection device connected to the connecting pipe 15 is activated. Dust generated during the crushing process is collected through the suction holes 17 on the suction pipe 16. A protective net 18 prevents large particles from entering the suction pipe 16, ensuring effective dust removal. The entire process, through the synergistic action of the crushing structure 3 and the dust collection assembly 4, achieves efficient conveying and dust control of calcium carbonate materials, improving equipment operating efficiency and the working environment.

[0022] Furthermore, the first rotating shaft 10 and the second rotating shaft 11 on the crushing structure 3 are rotatably installed in the shaft holes opened on the feed pipe 6. The crushing blades 12 are located inside the feed pipe 6. The reduction motor 9 on the crushing structure 3 is fixedly installed at the outer end of the feed pipe 6, and the transmission gear 13 is located on the outer side of the feed pipe 6. The first rotating shaft 10 of the crushing structure 3 is driven to rotate by the reduction motor 9, and the second rotating shaft 11 is driven to rotate in the opposite direction through the meshing transmission gear 13. The crushing blades 12 on the first rotating shaft 10 and the second rotating shaft 11 are arranged in a cross-staggered manner to ensure that the material is fully sheared and crushed in the feed pipe 6, effectively decomposing calcium carbonate agglomerates. The cross arrangement of the crushing blades 12 enhances the crushing efficiency and reduces the risk of material blockage.

[0023] Furthermore, the dust collection pipe 16 on the dust removal component 4 is fixedly inserted into the mounting hole 8 opened on the tapered tube 7. One end of the dust collection pipe 16 is also fixedly connected to the inner wall of the tapered tube 7. The connecting base pipe 14 is located on the outside of the tapered tube 7. The connecting pipe 15 is connected to the dust collection equipment. Several dust collection holes 17 are opened on the lower side wall of the dust collection pipe 16. The protective net 18 is fixedly installed in the dust collection holes 17. The dust removal component 4 is connected to the dust collection equipment through the connecting pipe 15. The dust collection holes 17 on the dust collection pipe 16 are evenly distributed for efficient adsorption of dust generated during the crushing process. The mesh size of the protective net 18 is 0.5mm to 1mm, which can effectively block larger particles from entering the dust collection pipe 16 and ensure that the dust is smoothly sucked up.

[0024] Finally, by setting the crushing structure 3 inside the feed hopper 2, the agglomerates in the calcium carbonate material can be effectively crushed, preventing blockage of the double helical auger inside the main body 1 of the double helical conveyor, ensuring the continuity and stability of material conveying, while improving equipment operating efficiency and reducing downtime due to malfunctions; by setting the dust removal component 4 on the feed hopper 2, the dust generated by the calcium carbonate material crushed by the crushing structure 3 inside the feed hopper 2 can be efficiently collected and removed, significantly improving the working environment, reducing the harm of dust to the health of operators, and meeting environmental protection requirements.

[0025] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
