Description

Technical Field

[0001] This utility model relates to the field of acid-resistant coated calcium carbonate preparation technology, specifically a vibrating sieving device for preparing acid-resistant coated calcium carbonate. Background Technology

[0002] Calcium carbonate is an inorganic compound, commonly known as limestone, stone powder, marble, etc. Its main component is calcite, with the chemical formula CaCO3. It is neutral, practically insoluble in water, but soluble in hydrochloric acid. It is a common substance on Earth, found in rocks such as aragonite, calcite, chalk, limestone, marble, and travertine, and is also a major component of animal bones and shells. Screening of the raw materials is necessary in the preparation of acid-resistant coated calcium carbonate.

[0003] A crushing and screening device for preparing nano-calcium carbonate particles, with announcement number CN214262131U, has auxiliary crushing blocks welded to the inner wall of the crushing chamber; a crushing chain installed at one end of the rotating shaft; an inclined return platform welded to the bottom of the rotating shaft; a grinding blade welded to the bottom of the inclined return platform; and a crushing blade located on the same plane as the inclined return platform near the rotating shaft. This structure effectively ensures that when encountering unqualified small materials, they can be ground through the gap between the grinding blade and the coarse filter screen.

[0004] There are some shortcomings in its use. Raw materials may clog the screen, reducing the screening quality and making the screening incomplete, thus reducing the practicality of the screening equipment. In addition, it can only screen the raw materials once, which also limits the scope of application. Therefore, we have proposed a vibrating screening equipment for the preparation of acid-resistant coated calcium carbonate. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0024] For examples, please refer to Figures 1-4 This utility model provides a technical solution:

[0025] A vibrating sieving device for preparing acid-resistant coated calcium carbonate includes a base plate 1. A sieving box 4 is fixedly connected to the top of the base plate 1. The inner wall of the sieving box 4 is provided with a side groove 16 and a sliding groove 17. A first screen 6 is slidably connected in the side groove 16. A spring rope 7 is fixedly connected between the first screen 6 and the side groove 16. A bottom groove 8 is provided at the bottom of the first screen 6. A drive motor 5 is installed on the outside of the sieving box 4. A rotating rod 10 is fixedly connected to the output end of the drive motor 5. An eccentric plate 9 is fixedly connected to the outer surface of the rotating rod 10. The eccentric plate 9 is positioned opposite to the bottom groove 8 and extends into the bottom groove 8 and abuts against the bottom groove 8. A second screen 13 is slidably connected in the sliding groove 17. A connecting spring 14 is fixedly connected between the second screen 13 and the sliding groove 17.

[0026] In this embodiment, as Figure 1 and Figure 2As shown, a damping rod 15 is provided inside the connecting spring 14, a miniature cylinder 11 is installed at the bottom of the screening box 4, and a stop plate 12 is fixedly connected to the top of the miniature cylinder 11. The stop plate 12 is circular in shape and is adsorbed to the second screen 13. The second screen 13 is located at the bottom of the first screen 6. A collection box 3 is abutted against the surface of the bottom plate 1. The collection box 3 is located directly below the screening box 4. The collection box 3 is made of stainless steel. A side cover 18 is abutted against the side of the screening box 4. The side cover 18 is opposite to the second screen 13.

[0027] The eccentric plate 9 can be rotated by the power of the drive motor 5, so that the eccentric plate 9 and the first screen 6 are in cyclic contact, thereby causing the first screen 6 to vibrate. At the same time, the second screen 13 can be moved up and down by the power of the micro cylinder 11, which can prevent the raw material from being blocked in the first screen 6 and the second screen 13 and improve the screening effect of the raw material.

[0028] In this embodiment, as Figure 3 and Figure 4 As shown, a self-locking caster wheel 2 is provided at the bottom of the base plate 1. The caster wheel 2 is movably connected to the base plate 1. The mesh diameter of the first screen 6 is 1.5 times that of the mesh diameter of the second screen 13. The first screen 6 and the second screen 13 are both rectangular in shape. Multiple sets of spring ropes 7 are provided, and each set of spring ropes 7 is located at the top corner of the first screen 6. The rotating rod 10 is made of stainless steel and is located at the bottom of the side groove 16.

[0029] The raw materials can be screened twice by the first screen 6 and the second screen 13, which improves the screening quality of the raw materials. At the same time, the raw materials can be collected by the collection box 3, making the screening device more practical.

[0030] The working process of this utility model is as follows: When the vibrating screening equipment for preparing acid-resistant coated calcium carbonate designed in this scheme is in operation, the raw material for preparing calcium carbonate is placed in the screening box 4, and then all external electrical switches are turned on. When the drive motor 5 is working, it drives the rotating rod 10 and the eccentric plate 9 to rotate, so that the eccentric plate 9 and the bottom groove 8 circulate and abut against each other. This drives the first screen 6 to move up and down in the side groove 16. Then, under the elastic force of the spring rope 7, the first screen 6 vibrates, which can initially screen the raw material. Then, the raw material falls back onto the surface of the second screen 13. Under the power of the micro cylinder 11, the second screen 13 moves up and down. Then, through the elasticity of the connecting spring 14 and the damping rod 15, the second screen 13 can vibrate, which can screen the raw material again, improve the screening quality of the raw material, and let the screened raw material fall into the collection box 3 for collection.

[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.
