Description

Technical Field

[0001] This utility model relates to the field of light calcium carbonate production technology, specifically to a device for removing impurities in light calcium carbonate production. Background Technology

[0002] Light calcium carbonate, also known as precipitated calcium carbonate, is a type of light calcium carbonate. It is used as a filler in industries such as rubber, plastics, papermaking, coatings, and inks. It is also widely used in organic synthesis, metallurgy, glass, and asbestos production.

[0003] Since light calcium carbonate ore contains a small amount of iron, it needs to be removed during production to improve the purity of heavy calcium carbonate. Currently, when removing iron from light calcium carbonate, it is often transported by conveyor belt and then subjected to iron removal equipment. However, the use of conveyor belts for iron removal of light calcium carbonate can easily lead to accumulation, making it difficult to effectively remove iron from the accumulated calcium carbonate, resulting in poor iron removal efficiency. A search revealed that patent document CN219273327U discloses an iron removal device for heavy calcium carbonate production, which also suffers from the same problem. Utility Model Content

[0004] The purpose of this invention is to provide an impurity removal device for the production of light calcium carbonate, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a device for removing impurities in the production of light calcium carbonate, comprising an iron removal box, and further comprising:

[0006] The iron removal box has inlet holes on both sides of the top. The top of the iron removal box is fixed with an inlet box. The top of the inlet box is fixed with a first motor. The output shaft of the first motor is bolted with a rotating rod. Several stirring rods are fixed around the surface of the rotating rod. Several push plates are fixed around the surface of the rotating rod.

[0007] A fixed frame is fixed inside the iron removal box, and several strong magnetic rods are provided on the inner side of the fixed frame.

[0008] A second motor is fixed to the right side of the iron removal box. The output shaft of the second motor is bolted with a screw. The other end of the screw is rotatably connected to the inside of the iron removal box. A screw sleeve is threaded onto the surface of the screw. A cleaning plate is fixed to the bottom of the screw sleeve and is movably connected to the surface of the strong magnetic rod. A screening plate is fixed inside the iron removal box.

[0009] Preferably, a movable rod is fixed at the front of the iron removal box, and a movable block is movably connected to the surface of the movable rod. The bottom of the movable block is fixed to the top of the cleaning plate.

Detailed Implementation

[0021] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0022] Please see Figure 1-4 As shown, a device for removing impurities in the production of light calcium carbonate includes an iron removal box 1. Both sides of the top of the iron removal box 1 have inlet holes 2. A feed box 3 is fixed to the top of the iron removal box 1. A first motor 4 is fixed to the top of the feed box 3. A rotating rod 5 is bolted to the output shaft of the first motor 4. Several stirring rods 6 are fixed around the surface of the rotating rod 5. Several push plates 7 are fixed around the surface of the rotating rod 5. A fixing frame 8 is fixed inside the iron removal box 1, and several strong magnetic rods 9 are arranged inside the fixing frame 8. A second motor 10 is fixed to the right side of the iron removal box 1. A screw 11 is bolted to the output shaft of the second motor 10. The other end of the screw 11 is rotatably connected to the interior of the iron removal box 1. A threaded sleeve 12 is threaded onto the surface of the screw 11. A cleaning plate 13 is fixed to the bottom of the threaded sleeve 12, and the cleaning plate 13 is movably connected to the surface of the strong magnetic rods 9. A screening plate 19 is fixed inside the iron removal box 1.

[0023] In addition to the movable rod 14 fixed at the front of the iron box 1, the movable block 15 is movably connected to the surface of the movable rod 14. The bottom of the movable block 15 is fixed to the top of the cleaning plate 13, so as to provide auxiliary limit for the cleaning plate 13 and facilitate its left and right movement.

[0024] A collection box 16 is movably connected to the left side of the iron removal box 1, and a handle is fixed to the left side of the collection box 16. This allows for the unified collection and treatment of iron filings that fall during cleaning. Support plates 17 are fixedly connected to the front and rear sides of the left side of the iron removal box 1. Slide grooves 18 are provided on both the front and rear sides of the collection box 16. The other end of the support plate 17 is movably connected to the inside of the slide groove 18. This provides auxiliary support for the collection box 16 and maintains its stability during movement. Sealing gaskets are provided on the surface of the collection box 16 and the inner wall of the movable sliding groove on the left side of the iron removal box 1 to prevent impurities from floating out through the sliding groove.

[0025] In addition to the collection box 20 being connected to the inside of the iron box 1, it is convenient to collect and process the impurities after screening.

[0026] Working principle: During use, the controller starts the strong magnetic rod 9, simultaneously starting the first motor 4, which drives the rotating rod 5, stirring rod 6, and push plate 7 to rotate. Light calcium carbonate is then poured into the feed hopper 3. As the rotating rod 5, stirring rod 6, and push plate 7 rotate, the light calcium carbonate is dispersed and fed in. The fed light calcium carbonate falls between the strong magnetic rods 9, and as it passes over the surface of the strong magnetic rods 9, it attracts iron powder from the surface of the light calcium carbonate. Subsequently, the light calcium carbonate falls onto the surface of the screening plate 19 for sieving. After sieving... The light calcium carbonate will fall into the collection box 20. The larger light calcium carbonate impurities after screening will slide out through the right side of the iron removal box 1. After the light calcium carbonate is cleaned, in order to facilitate better iron removal, the chute 18 can be slid into the iron removal box 1, and the strong magnetic rod 9 can be turned off by the controller, so that some iron powder falls into the collection box 16. Then the second motor 10 is started, which drives the screw 11 to rotate and drives the screw sleeve 12 and the cleaning plate 13 to move to the left, thereby cleaning the iron powder remaining on the surface of the strong magnetic rod 9.
