[0002] In the current field of calcium carbonate production technology, modified calcium carbonate is a chemical substance produced by activating the surface of heavy or light calcium carbonate. It is also known as activated calcium carbonate. Its particle size is usually less than 0.1 micrometers. After the surface is treated with substances such as fatty soaps, it has hydrophobic and colloidal activation properties. It is soluble in water and decomposes in acid. It is widely used in industries such as rubber, plastics, papermaking, and coatings. It can improve the mechanical properties and impact resistance of products and also has the functions of filler and reinforcement. During its processing, it needs to be crushed into granular powder. Therefore, a calcium carbonate crushing device is required to process it into calcium carbonate granular powder.

[0039] 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.
[0040] Please see Figure 1-3This utility model provides a technical solution: a pulverizing device for processing modified calcium carbonate, including a processing box 1, a support 11 fixedly installed on the bottom wall of the processing box 1, and a discharge mechanism 3 for discharging granular powder. The discharge mechanism 3 includes a discharge hopper 34, with inner lining plates 35 on both sides of the inner wall of the discharge hopper 34. A connecting frame 36 that slides and connects the discharge hopper 34 is installed on the outer wall of the inner lining plate 35. The connecting frame 36 is U-shaped, with two vibration springs 361 fitted on the connecting frame 36, and a vibration motor 37 fixedly installed on the connecting frame 36. Multiple connecting rods 351 that slide and connect the discharge hopper 34 are fixedly installed on the outer wall of the inner lining plate 35, and a stop block is fixedly installed at the end of the connecting rod 351.
[0041] When calcium carbonate granules are placed in the discharge hopper 34, the vibration motor 37 drives the connecting frame 36 to vibrate. The connecting frame 36 pulls the inner liner 35 to move. At the same time, one end of the vibration spring 361 abuts against the connecting frame 36, and the other end abuts against the outer wall of the discharge hopper 34, so that the two inner liner 35 vibrate inside the discharge hopper 34 to prevent the granules from clogging inside the discharge hopper 34. Meanwhile, the connecting rod 351 slides on the discharge hopper 34 to prevent the inner liner 35 from falling off. The discharge hopper 34 can be supported by a support frame to facilitate receiving the crushed granules below it.
[0042] The crushing mechanism 2 is used to crush calcium carbonate. The crushing mechanism 2 is installed on the processing box 1. The crushing mechanism 2 includes a rotating shaft 21, which is rotatably installed inside the processing box 1. Multiple partitions 212 are fixedly installed on the outer wall of the rotating shaft 21. Multiple crushing blocks 213 are fixedly installed between the multiple partitions 212. The multiple crushing blocks 213 are arranged around the rotating shaft 21.
[0043] The rotating shaft 21 drives multiple crushing blocks 213 to rotate, thereby crushing the calcium carbonate raw material using the multiple rotating crushing blocks 213.
[0044] A rotating disk 211 with a tapered portion on its upper surface is fixedly installed on the upper end of the rotating shaft 21. A receiving disk 23 is fixedly installed on the bottom wall inside the processing box 1. The receiving disk 23 has a tapered portion. The rotating shaft 21 passes through the receiving disk 23. A geared motor 22 is fixedly installed on the support 11. The geared motor 22 is connected to the rotating shaft 21.
[0045] Furthermore, the conical rotating disk 211 facilitates the sliding of raw materials from the rotating disk 211, and the geared motor 22 drives the rotating shaft 21 to rotate through the right angle reducer, so that the granular powder falls onto the receiving disk 23.
[0046] A sleeve 24 is fixedly installed on the inner wall of the processing box 1. A flow channel is formed between the sleeve 24 and the inner wall of the processing box 1. An inclined guide plate 241 is provided on the inner wall of the sleeve 24. An annular mating block 242 that cooperates with the crushing block 213 is provided on the inner wall of the sleeve 24.
[0047] In addition, the flow channel between the sleeve 24 and the processing box 1 facilitates airflow, the inclined guide plate 241 facilitates the sliding of granular powder, and the mating block 242 cooperates with multiple crushing blocks 213, and the inner wall of the mating block 242 is inclined to facilitate crushing.
[0048] A filter cylinder 25 is rotatably installed on the top wall inside the processing box 1. A filter screen is provided on the outer wall of the filter cylinder 25. A material extraction pipe 32 with a connecting sleeve 24 is fixedly installed on the upper surface of the processing box 1. An induced draft fan 31 is fixedly installed on the material extraction pipe 32. The induced draft fan 31 is connected to the discharge hopper 34 through the conveying pipe 33.
[0049] In addition, the blower 31 extracts the gas inside the processing box 1. A screen can be installed on the bottom wall of the processing box 1 to facilitate air flow. The blower 31 creates negative pressure, causing the granular powder on the receiving tray 23 to move upwards and fall onto the filter cylinder 25 through the inclined guide plate 241. The filter cylinder 25 is then screened by the filter screen. The filter cylinder 25 can be rotated by a motor, which increases the screening efficiency. Larger granular powder falls onto the rotating disc 211 for secondary crushing. The granular powder entering the filter cylinder 25 is drawn away by the blower 31, causing the granular powder lens conveying pipe 33 to fall into the discharge hopper 34.
[0050] A guide pipe 121 is fixedly installed on the outer wall of the processing box 1. The guide pipe 121 passes through the outer wall of the processing box 1 and is positioned above the rotating disk 211. A feeding hopper 12 is fixedly installed on the guide pipe 121.
[0051] Specifically, the crushed raw materials are poured in through the hopper 12 and the guide pipe 121 to facilitate feeding and crushing.
[0052] The workflow of this embodiment is as follows: Please refer to... Figure 1-3A crushing device for processing modified calcium carbonate can be installed on a support frame to connect the power supply and control the device. The crushed raw material is poured in through the hopper 12 and the guide pipe 121. The conical rotating disk 211 facilitates the sliding of the raw material. The geared motor 22 drives the rotating shaft 21 to rotate through a right-angle reducer. The rotating shaft 21 drives multiple crushing blocks 213 to rotate, thereby utilizing the multiple rotating crushing blocks 213 to cooperate with the mating block 242. The inner wall of the mating block 242 is inclined to crush the calcium carbonate raw material. The induced draft fan 31 extracts the gas inside the processing chamber 1. A screen can be embedded in the bottom wall of the processing chamber 1 to facilitate airflow. The induced draft fan 31 creates a negative pressure, causing the material on the receiving tray 23 to... The granular powder moves upwards by the flow and falls onto the filter cylinder 25 through the inclined guide plate 241. It is then sieved by the filter screen on the filter cylinder 25. The filter cylinder 25 can be rotated by a motor, which increases the sieving efficiency. Larger particles fall onto the rotating disc 211 for secondary crushing. The granular powder entering the filter cylinder 25 is drawn away by the blower 31 and falls into the discharge hopper 34 through the conveying pipe 33. When the calcium carbonate granular powder is in the discharge hopper 34, the vibrating motor 37 drives the connecting frame 36 to vibrate. The connecting frame 36 pulls the inner liner plate 35 to move. At the same time, one end of the vibrating spring 361 abuts against the connecting frame 36 and the other end abuts against the outer wall of the discharge hopper 34, so that the two inner liner plates 35 vibrate inside the discharge hopper 34, preventing the granular powder from clogging inside the discharge hopper 34.
