Description

Technical Field

[0001] The invention relates to the technical field of mineral processing, in particular to a device for mineral processing of ultrafine heavy calcium carbonate powder. Background Art

[0002] Ultrafine ground calcium carbonate powder is a micron- or even nanometer-sized powder material made from raw materials such as calcite and chalk through mechanical crushing, grinding, and grading. Its particle size typically ranges from 0.5 to 10 microns, and its unique properties make it a key component in a wide range of applications. In the plastics industry, it can serve as a filler, significantly reducing production costs while also improving the rigidity, hardness, and dimensional stability of plastic products, enhancing their durability. In the rubber industry, the addition of ultrafine ground calcium carbonate enhances the rubber's tensile strength and abrasion resistance, optimizing product performance. In coatings, it improves hiding power, imparts a superior gloss and smoothness, and contributes to the creation of high-quality coatings. Compared to standard calcium carbonate, ultrafine ground calcium carbonate powder has a larger surface area, enabling it to better bond with other materials, resulting in more pronounced effects. Furthermore, its high purity and low impurity content make it particularly useful in industries requiring the highest purity levels. With the continuous optimization of production processes, the quality of heavy calcium carbonate ultrafine powder has not only been steadily improved, but the cost has also been gradually reduced. It is expected to be widely used in more fields in the future, providing strong support for the development of related industries.

Then, the holding device is used to wash the mineral with water through the water holding device, which can further clean the impurities on the surface of the mineral. After cleaning, the minerals inside the holding device are continued to be shaken by the protrusions to reduce the moisture on the surface of the mineral.

[0017] 2. In the present invention, the air circulation device can be used to blow away impurities on the surface of the mineral to achieve the effect of cleaning the mineral. At the same time, the air flow output by the air circulation device is also blown toward the surface of the holding device that has been washed with water from the inside of the water holding device, thereby achieving the effect of air-drying the holding device.

A water holding device 5 is provided at the bottom of the support rail 1 and the driving rail 15.

[0026] Specifically, the driving track 15 can drive the holding device 2 to operate on the entire surface of the device; the holding device 2 can be used to place heavy calcium carbonate ultrafine powder minerals; the driving device 10 can output power, thereby driving the support track 1 to move; the support track 1 can support both sides of the holding device 2, thereby enabling the holding device 2 to maintain balance during operation; the supporting device 16 can lift the support track 1 and the driving track 15, thereby enabling the subsequent water container 5 to enter the interior of the water container 5 from the upper part, and then come out from the interior of the water container 5, thereby achieving the effect of cleaning the minerals inside the holding device 2; The water device 5 can serve as a water source storage, and then the impurities on the surface of the minerals are washed away after passing through the water device 5; the support track 1 and the driving track 15 are in a downward arc shape when located inside the water device 5, thereby ensuring that the driving track 15 and the holding device 2 are completely immersed in the water device 5, thereby achieving the effect of washing the minerals; the aeration device 19 provided at the bottom of the water device 5 can generate a large number of bubbles inside the water device 5, thereby improving the cleaning effect of the minerals and the holding device 2; the protrusions 17 can lift up the two sides of the holding device 2, thereby destroying the balance of the holding device 2 during operation, thereby generating a vibration effect, and the protrusions 17 are located on the support track 1 inside the water device 5. The top is also located at the top of the support track 1 of the front and rear sections of the water holding device 5. When the support track 1 with the protrusions 17 is located at the top section of the first receiving tray 4, it can shake off impurities with low adhesion on the surface of the mineral, and then collect them through the first receiving tray 4; when the support track 1 with the protrusions 17 is located inside the water holding device 5, it can maintain vibration while washing the minerals with water, thereby further improving the washing effect; when the support track 1 with the protrusions 17 is located at the rear of the water holding device 5, it can shake off part of the water on the surface of the water-out mineral, thereby reducing the dehydration work of subsequent processing; the impurities inside the holding device 2 can be blown away from the mineral surface through the air circulation device 3, and at the same time, with the help of the protrusions The vibration effect of the block 17 improves the efficiency of blowing away impurities; thereby, the impurities are blown away by the air circulation device 3 while the convex block 17 shakes, and then the impurities on the surface of the mineral are further separated by the water source inside the water holding device 5, so that the impurity content of the mineral is greatly reduced, thereby solving the problem that the traditional mineral processing stage of heavy calcium carbonate ultrafine powder manufacturing is mostly directly crushed and then transported to the next stage, but because the original mineral contains more impurities, it will cause processing pressure in the subsequent stage, making it difficult to improve the processing efficiency; the opening section is opened in the middle of the support track 1, so that the mineral after mineral processing can be poured into the second storage tray 12 for collection;The opening section causes the holding device 2 to lose the stable support of the support rail 1. When the driving rail 15 continues to drive the holding device 2 to move, the bottom of the holding device 2 will contact the top of the top deflection device 13, causing the holding device 2 to tip toward the second receiving tray 12, thereby pouring the minerals into the second receiving tray 12. At the same time, the driving rail 15 continues to drive the holding device 2 to move. The holding device 2 then contacts the reset device 14, correcting the holding device 2 and moving forward. After further forward movement, the holding device 2 will reconnect with the support rail 1. The holding device 2 will continue to move forward to the side of the water holding device 5 near the air circulation device 3. The water source inside the water holding device 5 will clean the holding device 2 without minerals, thereby ensuring the cleanliness of the holding device 2. The holding device 2 will then continue to move in front of the air circulation device 3, and the air circulation device 3 will blow away the moisture on the surface of the cleaned holding device 2, and then the mineral holding work will continue.

The bottom of the holding basket 206 is fixedly connected to a stabilizing block 205, and a roller is provided inside the stabilizing block 205. The side wall of the roller is connected to the side wall of the support track 1, and an elastic rubber layer is provided on the outer side of the roller. The thickness of the elastic rubber layer is 3-5mm, and the elastic rubber layer contacts the side wall of the support track (1). The bottom of the holding basket 206 is provided with a card block 204, and the card block 204 is connected to the bottom of the holding basket 206 through a hinge 203.

When the holding basket 206 is operating normally, the fixing effect of the magnetic block 201 prevents the discharge door 202 from opening. When the minerals need to be poured out, the weight of the minerals inside the holding basket 206 is greater than the attraction of the magnetic block 201, and then the discharge door 202 is pushed open to complete the work of pouring out the minerals.

[0033] Please see the attached Figure 1 -Attached Figure 8 The supporting device 16 includes a connecting plate 161, the bottom of which is fixedly connected to a second supporting plate 162, one side of the connecting plate 161 is fixedly connected to the side wall of the support rail 1, and the other side of the connecting plate 161 is fixedly connected to the side wall of the drive rail 15.

The power of the fan inside the fan 304 is 50-100W, and the output wind speed is 8-12m / s.

[0036] Specifically, the mounting bracket 302 can be used to install the first air outlet 301 and the fan 304; the main air duct 305 can be used to convey the airflow output by the fan 304, and then convey the airflow to the first air duct 306 and the second air duct 307; the first air duct 306 can convey the airflow to the first air outlet 301; the second air duct 307 can convey the airflow to the second air outlet 303; the second air outlet 303 can convey the airflow to the aeration device 19 through the air pipe 18; the first air outlet 301 can be used to blow the airflow out, thereby The fan 304 can blow the water from the holding device 2 after washing to the holding device 2 for minerals, thereby achieving the purpose of drying, and at the same time blowing the water from the holding device 2 for minerals to the holding device 2, thereby achieving the purpose of blowing away impurities on the surface of the minerals. At the same time, since the angle of the fan 304 is obliquely downward, it can avoid blowing the water on the surface of the holding device 2 after washing to the inside of the holding device 2 for minerals.

[0037] The bumps 17 are semi-cylindrical, with a height of 8-12 mm, and are evenly distributed along the top surface of the support rail 1 . The distance between adjacent bumps 17 is 50-80 mm.

[0038] Specifically, the semi-cylindrical protrusions can avoid the rigid impact of sharp angles on the holding basket 206, reducing equipment wear while ensuring the vibration effect; the uniform spacing design makes the vibration frequency stable and the impurity stripping efficiency is improved by more than 30%.
