Description

Technical Field

[0001] This utility model relates to the field of calcium carbonate powder processing technology, specifically to a raw material feeding device for calcium carbonate powder processing. Background Technology

[0002] Calcium carbonate is a valuable resource with a wide range of uses, while limestone is the commercial name for a mineral raw material. Throughout human history, limestone has been widely used due to its abundant distribution and easy accessibility in nature. It is mainly used in the manufacture of products such as paper, rubber, paints, coatings, pharmaceuticals, cosmetics, animal feed, sealants, adhesives, and polishing.

[0003] A search revealed Chinese patent (CN222063428U) which includes a blower, a conveying duct connected to one side of the blower, a blower chamber connected to one side of the conveying duct, and a second conveying duct connected to one side of the blower chamber. The second conveying duct is connected to a calcium carbonate powder collection device. This invention conveys calcium carbonate powder into a housing via a hopper, and a crushing component crushes any clumps of the powder entering the housing. The crushed powder falls onto a partition frame, is then sieved by a screening component, and finally conveyed into the blower chamber via a guide frame. The powder is then transported by the working airflow of the blower. Through crushing and screening, the calcium carbonate powder is made finer, effectively preventing clumping and improving the conveying efficiency of the equipment.

[0004] The aforementioned patent proposes using a crushing component to crush the agglomerated calcium carbonate powder entering the chamber, causing the crushed calcium carbonate powder to fall onto a partition frame. The crushed calcium carbonate powder is then sieved by a screening component, and finally conveyed to the blower chamber via a guide frame. Finally, the calcium carbonate powder is conveyed by the working airflow of the blower. This method of conveying requires a high degree of sealing from subsequent processing equipment, and the single structure cannot adapt to various subsequent processing equipment, resulting in a limited range of applications. Therefore, we propose a calcium carbonate powder processing raw material feeding device. Summary of the Invention

[0005] To solve the above-mentioned technical problems, this application provides a raw material feeding device for calcium carbonate powder processing, including an electric lifting support, a metal support frame, and a crushing chamber. The top of the electric lifting support is provided with a limit plate, a motor is provided on the left side of the limit plate, and a rotating shaft is provided at the output end of the motor. Slide rails are provided on both the left and right sides of the limit plate, and sliding groove plates are slidably connected to the outer sides of the two slide rails. A pressure application mechanism is slidably connected inside the limit plate.

[0006] In some embodiments, a second rotating shaft is rotatably connected between the two slide plates, a third rotating shaft is rotatably connected between the two slide plates, a fourth rotating shaft is rotatably connected inside the limiting plate, a rubber conveyor belt is sleeved between the first rotating shaft, the second rotating shaft, the third rotating shaft, and the fourth rotating shaft, a scraper is provided at the bottom end of the two slide plates, and a baffle is provided at the top end of the two slide plates.

[0007] In some embodiments, the metal support frame is provided with an iron remover, a second motor is provided on the right side of the crushing chamber, a crushing roller mechanism is provided at the output end of the second motor, and a discharge port is provided on the left side of the crushing chamber.

[0008] In some embodiments, a control box is provided on the right side of the electric lifting support.

[0009] In some embodiments, the iron remover is located above the rubber conveyor belt, and the rotating shaft is located above the crushing roller mechanism.

[0010] In some embodiments, both of the slide plates are slidably connected to the outside of the limiting plate.

[0011] In some embodiments, the pressure application mechanism is rotatably connected to the inner wall of the rubber conveyor belt, and the scraper is located at the bottom of the rotating shaft three.

[0012] In summary, this utility model has at least the following beneficial effects: 1. The overall equipment operation is controlled by the control box, which drives the electric lifting bracket to adjust the height and simultaneously change the angle of the overall conveying mechanism; at the same time, the tension of the rubber conveyor belt is changed by the sliding pressure application mechanism, which drives the moving slide plate to adjust the length of the overall conveying mechanism, thereby realizing the free adjustment of the equipment angle and length, effectively adapting to different sites and user pre-processing work needs, and significantly improving the efficiency of equipment installation while saving installation space.

[0013] 2. A metal support frame positioned above the rubber conveyor belt adsorbs metallic impurities mixed in the ore, preventing the crushing roller mechanism from entering and causing severe wear. Simultaneously, baffles on both sides of the rubber conveyor belt ensure stable transport of the raw material. Scrapers act on the surface of the conveyor belt, removing residual processing material. The rubber conveyor belt transports the raw material from bottom to top to the crushing component's feed inlet, where the crushing roller mechanism performs squeezing and shearing actions to crush large pieces of ore. This achieves the beneficial effects of ensuring the service life of the crushing roller mechanism and product purity, preventing raw material from deviating from the transport path, reducing raw material waste to ensure full processing, facilitating subsequent processing procedures, and improving overall processing quality and efficiency.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Example 1 Please see Figures 1-3 This utility model provides a technical solution: A calcium carbonate powder processing raw material feeding device includes an electric lifting support 1, a metal support frame 14, and a crushing chamber 16. This device is used to convey, remove impurities from, and pre-treat raw materials for calcium carbonate powder processing, providing qualified raw materials for subsequent processing steps. The electric lifting support 1 is the core support component for height adjustment, the metal support frame 14 supports the impurity removal components, and the crushing chamber 16 provides a closed working space for raw material crushing. A limit plate 2 is installed at the top of the electric lifting support 1, which can position and limit the installation of various components connected to the top of the electric lifting support 1, preventing component misalignment and ensuring the stability of subsequent structural assembly. A motor 3 is installed on the left side of the limit plate 2, providing continuous power for the cyclic operation of the rubber conveyor belt 11, serving as the power source for raw material conveying. A rotating shaft 4 is installed at the output end of the motor 3, transmitting the power output from the motor 3 to the rubber conveyor belt 11. The rotating shaft 4 drives the rubber conveyor belt 11 to achieve cyclic movement through its own rotation, thereby completing the raw material conveying. Slide rails 5 are installed on both the left and right sides of the limit plate 2. The slide rail 5 provides a fixed guide path for the sliding of the slide plate 6, ensuring that the slide plate 6 moves smoothly along the preset direction and avoiding deviation that affects the length adjustment accuracy of the conveying mechanism. The slide plates 6 are slidably connected to the outer sides of the two slide rails 5. The slide plates 6 can slide along the slide rails 5 and drive the rotating shafts 8 and 9 to move synchronously by changing their own positions, thereby realizing the adjustment of the overall length of the conveying mechanism. The pressure application mechanism 7 is slidably connected inside the limiting plate 2. The pressure application mechanism 7 can adjust the pressure applied to the inner wall of the rubber conveyor belt 11 by sliding, thereby changing the tension of the rubber conveyor belt 11 and ensuring that the rubber conveyor belt 11 always maintains a suitable tension to avoid slippage. A control box 20 is set on the right side of the electric lifting bracket 1. The control box 20 can centrally control the operation of the entire equipment. Users can adjust parameters such as the height of the electric lifting bracket 1, the angle and length of the conveying mechanism through it to adapt to different working environments. The two slide plates 6 are slidably connected to the outer sides of the limiting plate 2. The double sliding connection structure further improves the stability of the slide plates 6 when sliding and ensures the reliability of the length adjustment of the conveying mechanism.

[0018] Example 2 Please see Figures 4-5This utility model provides a technical solution: a second rotating shaft 8 is rotatably connected between two chute plates 6. The second rotating shaft 8 can move with the chute plates 6 and, in conjunction with other rotating shafts, supports the rubber conveyor belt 11 to ensure its smooth operation; a third rotating shaft 9 is rotatably connected between the two chute plates 6. The third rotating shaft 9 supports the operation of the rubber conveyor belt 11 on one hand and guides the raw material precisely to the crushing roller mechanism 18 on the other hand; a fourth rotating shaft 10 is rotatably connected inside the limiting plate 2. The fourth rotating shaft 10, in conjunction with other rotating shafts, disperses the force on the rubber conveyor belt 11, avoiding excessive local force that could cause damage and extending its service life; a rubber conveyor belt 11 is fitted between the first rotating shaft 4, the second rotating shaft 8, the third rotating shaft 9, and the fourth rotating shaft 10. The rubber conveyor belt 11 circulates the raw material from bottom to top. The material is conveyed to the feed inlet of the crushing component for continuous material transport. Scrapers 12 are installed at the bottom of the two chute plates 6. These scrapers remove residual material from the rubber conveyor belt 11, preventing some material from being unprocessed. Baffles 13 are installed at the top of both chute plates 6. These baffles prevent the material from deviating from the rubber conveyor belt 11 during transport, ensuring all material is transported to the designated location. A pressure applying mechanism 7 is rotatably connected to the inner wall of the rubber conveyor belt 11. This connection prevents the pressure applying mechanism 7 from obstructing the operation of the rubber conveyor belt 11 while ensuring uniform tension adjustment. The scraper 12 is located at the bottom of the rotating shaft 9. This position allows the scraper 12 to more thoroughly remove residual material when the rubber conveyor belt 11 turns, improving the scraping effect.

[0019] The metal support frame 14 is equipped with a magnetic separator 15, which can adsorb metal impurities in the raw materials on the rubber conveyor belt 11 and prevent them from entering the crushing roller mechanism 18. A second motor 17 is located on the right side of the crushing chamber 16, providing power to the crushing roller mechanism 18 and ensuring sufficient crushing capacity. The output end of the second motor 17 is connected to the crushing roller mechanism 18, which crushes large pieces of ore through a "squeezing + shearing" action, facilitating subsequent processing and improving overall processing quality and efficiency. A discharge port 19 is located on the left side of the crushing chamber 16, allowing the crushed raw materials to be discharged, thus connecting the crushing process with subsequent processes. The magnetic separator 15 is located above the rubber conveyor belt 11, ensuring full coverage of the raw material conveying area and maximizing the adsorption of metal impurities to guarantee product purity. The rotating shaft 9 is located above the crushing roller mechanism 18, ensuring that the raw materials on the rubber conveyor belt 11 accurately fall into the crushing roller mechanism 18, preventing material loss and ensuring continuous crushing operations.

[0020] Based on the above embodiments, the following is the complete working principle of the above embodiments: When pre-processing is required, the operation of the entire equipment is controlled by the control box 20. The height of the electric lifting bracket 1 can be adjusted according to the user's needs, and the angle of the overall conveying mechanism can be changed. The tension on the rubber conveyor belt 11 is changed by the sliding pressure application mechanism 7, thereby changing the length of the overall conveying mechanism by moving the slide plate 6. The angle and length of the entire equipment can be freely adjusted, adapting to different working environments according to site and user needs, saving space while increasing installation efficiency. The metal support frame 14 is located on the rubber... The rubber conveyor belt 11 effectively adsorbs metallic impurities mixed in the ore, preventing them from entering the crushing roller mechanism 18 and causing severe wear to the crushing roller mechanism 18, thus ensuring product purity. The baffle 13 ensures that the raw materials do not deviate from the rubber conveyor belt 11 during transportation. The scraper 12 is used to scrape off the processing material remaining on the rubber conveyor belt 11, preventing a small portion of the raw materials from being unable to be effectively processed. The raw materials are transported from bottom to top to the feed inlet of the crushing component via the rubber conveyor belt 11. Through the squeezing and shearing action of the crushing roller mechanism 18, large pieces of ore are crushed to facilitate subsequent processing and improve the overall processing quality and efficiency.
