Description

Technical Field

[0001] This utility model relates to the technical field of feeding devices, and in particular to a feeding device for calcining diatomaceous earth raw soil. Background Technology

[0002] Diatomaceous earth is a non-metallic mineral with a porous structure and strong chemical stability. It is widely used in filter materials, adsorbents, catalyst carriers, building materials and other fields. Its processing quality (such as particle uniformity, purity and dryness) directly affects the performance of downstream products. Therefore, before core processes such as calcination, it is necessary to remove impurities, break up clumps and reduce moisture content through pretreatment such as crushing and drying to lay the foundation for subsequent processing.

[0003] Although existing feeding devices for diatomaceous earth calcination can meet most needs, they are prone to clumping and sticking when exposed to damp diatomaceous earth, causing blockages and serious dust leakage during transport. In addition, the accumulation of damp materials may lead to mold growth or spontaneous combustion. During the heating and drying process, improper control of the internal pressure of the equipment may cause damage due to excessive pressure, posing a safety risk. Furthermore, a single crushing stage is insufficient to completely break up clumps or remove impurities, which can easily lead to uneven heating during subsequent calcination and reduce the quality of the finished product. Therefore, a new feeding device for diatomaceous earth calcination is proposed to solve the above problems. Utility Model Content

The core component generates hot air inside the protective shell 20 through electric heating, providing a heat source for the drying of diatomaceous earth in the working chamber 2, thus achieving pre-treatment drying of the material. A conveying pipe 21 is installed on the side of the protective shell 20, which is used to connect the protective shell 20 and the working chamber 2.

The other end of the conveying pipe 21 is installed on the side of the working chamber 2. A connecting pipe 22 is installed on the top of the protective shell 20. An air pump 23 is fixedly connected to the top of the working chamber 2. The connecting pipe 22 is used to connect the air pump 23 and the protective shell 20. The other end of the connecting pipe 22 is installed at the bottom of the air pump 23. An air outlet pipe 24 is fixedly connected to the side of the air pump 23, which is used to release the pressure inside the protective shell 20. A support frame 2 14 is fixedly connected to the side of the working chamber 2. A motor 2 9 is installed inside the support frame 2 14, which is used to support the motor 2 9. A gear 11 is fixedly connected to the output end of the motor 2 9.

[0032] Reference Figure 2 , Figure 4 , Figure 5 and Figure 6A housing 10 is fixedly connected to the middle of the working box 2. To protect the internal components and prevent misalignment during operation, a gear 12 is rotatably connected to the middle of the housing 10. Gear 11 and gear 12 mesh with each other. A crusher 13 is rotatably connected inside the working box 2. The crusher 13 is driven by the cooperation of gear 11 and gear 12. The crusher 13 is used for the initial crushing of diatomaceous earth. A motor 6 is fixedly connected to the outside of the feed pipe 1. A fixed hopper 8 is fixedly connected to the output end of the motor 6. The motor 6 drives the fixed hopper 8, which is used to quantitatively convey diatomaceous earth, controlling the amount of material entering the working box 2. This ensures a stable supply of raw materials and prevents excessive material input from causing equipment blockage. The feed hopper 8 rotates in the middle of the feed pipe 1. The motor 15 is installed in the middle of the support frame 14. The output end of the motor 15 is fixedly connected to the stirring rod 16. The motor 15 is used to control the stirring rod 16. The stirring rod 16 is used for secondary crushing of diatomite. The stirring rod 16 is rotatably connected to the middle of the working box 2. The crusher 13 is fixedly connected to the middle of the gear 11 and gear 2 12. The outer side of the working box 2 is fixedly connected to the bracket 17. The bracket 17 is used to fix the working box 2. The bottom of the bracket 17 is fixedly connected to the base 18. The box body 4 is located on the top of the base 18. The bottom of the motor 6 is fixedly connected to the support frame 7. The support frame 7 is used to support the motor 6. The base 18 is used to support the box body 4 and the working box 2.

[0033] Working principle: First, diatomaceous earth is fed into the feed pipe 1. Then, motor 6 is started, which drives the fixed hopper 8 to rotate. The fixed hopper 8 dispenses a measured amount of diatomaceous earth into the working box 2, preventing excessive filling and blockage. Once the diatomaceous earth is poured into the working box 2, motor 9 is started. Motor 9 drives gear 11 to rotate, which in turn drives gear 12. As gears 11 and 12 rotate simultaneously... This will drive the crusher 13 to perform the first crushing of the diatomaceous earth, preventing lumps or other impurities from forming. After crushing, the material will be transferred to the stirring rod 16. When the motor 3 15 starts, it will drive the stirring rod 16 to rotate, further crushing the diatomaceous earth. This double protection ensures the quality of the calcined diatomaceous earth product. The processed diatomaceous earth will then fall into the funnel 19 and be conveyed by the auger 3 to the inside of the box 4. Finally, the processed diatomaceous earth will flow out from the discharge pipe 5.

[0034] When the equipment is running, the heating coil 25 can be heated. While the heating coil 25 is heating, the hot air generated inside the protective shell 23 will be transferred to the working box 2 through the conveying pipe 21. At this time, the hot air will dry the diatomaceous earth inside the working box 2, so that the diatomaceous earth is well dispersed after drying, which can reduce blockage and dust leakage during the conveying process, and reduce the risk of mold or spontaneous combustion caused by the accumulation of damp materials. While the heating coil 25 is heating, the air pump 23 can be started. At this time, with the cooperation of the air pump 23 and the air outlet pipe 24, the excessive pressure inside the protective shell 23 can be released in time, avoiding damage to the equipment due to excessive internal pressure caused by heating, thus protecting the working box 2 and the protective shell 23.
