Description

Technical Field

[0001] The utility model relates to the technical field of calcium carbonate processing, in particular to a drying device for heavy calcium carbonate processing. Background Art

[0002] Calcium carbonate is an inorganic compound with the chemical formula CaCO3. It is a common chemical substance that is widely found in nature. For example, limestone, coral, and shells are mainly composed of calcium carbonate. Calcium carbonate is used as a component of building materials, especially in cement, lime, and gypsum. Heavy calcium carbonate and light calcium carbonate are the two main forms of calcium carbonate, which differ in properties and applications. Heavy calcium carbonate has a higher density, a dense crystal structure, and a higher hardness. It mainly comes from limestone or marble, which contain a higher proportion of heavy calcium carbonate. Light calcium carbonate has a relatively low density, a relatively loose crystal structure, and a lower hardness. Most light calcium carbonate comes from the skeletons and shells of organisms such as shells and corals, or is obtained through artificial synthesis.

[0003] Calcium carbonate is produced after marble is crushed. Calcium carbonate easily absorbs moisture in the air, especially in a high humidity environment, and is prone to form lumps or agglomerates. When calcium carbonate acts as a filler, excessive moisture will affect the physical properties and chemical stability of the product. Therefore, a drying device for heavy calcium carbonate processing is proposed to solve the above-mentioned problems. Utility Model Content

[0019] In the embodiment, Figure 1-3A drying device for processing heavy calcium carbonate is provided, comprising a frame 1, a partition 2 is fixedly installed in the frame 1, and the partition 2 divides the internal space of the frame 1 into two equal areas, a first conveyor belt 3 and a second conveyor belt 4 are arranged in the frame 1, the first conveyor belt 3 and the second conveyor belt 4 are respectively located in the two areas, a material tray 5 for holding calcium carbonate is arranged on the first conveyor belt 3, a drying device 6 for supplying air to the material tray 5 is arranged on the frame 1, a protective layer 7 is arranged on the outside of the frame 1, a material transfer assembly 8 for conveying the material tray is arranged between the first conveyor belt 3 and the second conveyor belt 4, and the heavy calcium carbonate raw material to be dried is loaded The calcium carbonate is moved to the material tray 5 on the first conveyor belt 3 located in the area above the partition 2, and the first conveyor belt 3 is started to move the material tray 5 carrying calcium carbonate toward the material transfer component 8. During the movement, the drying device 6 is started to supply air to the calcium carbonate raw material in the material tray 5, and the water in the raw material is evaporated by wind convection to achieve the drying purpose. The calcium carbonate that has been dried for the first time is moved to the loading end of the material transfer component 8, and the calcium carbonate is transferred to the second conveyor belt 4 through the material transfer component 8. At the same time, during the transportation process, the posture of the calcium carbonate is adjusted by the vibration of the elastic member 84, so that the calcium carbonate is conveniently dried for the second time on the second conveyor belt 4, thereby further increasing the drying effect.

[0020] Reference Figure 1-3 , wherein the drying device 6 comprises an air flow distribution box 61, and a plurality of air flow distribution boxes 61 are arranged at an evenly spaced interval on one side of the frame 1, one end of one of the air flow distribution boxes 61 is connected to an air supply device, and two adjacent air flow distribution boxes 61 are connected via an air pipe 62, and the air outlet end of the air flow distribution box 61 is connected to two groups of air inlet pipe networks 63, and the two air inlet pipe networks 63 are respectively located above the first conveyor belt 3 and the second conveyor belt 4, and the first conveyor belt 3 and the second conveyor belt 4 are both provided with air outlet pipe networks 64, and the air outlet end of the air outlet pipe network 64 is connected to a dehumidification fan 65;

[0021] Through the above-mentioned structural arrangement, the air supply device provides power for the entire drying device, generates and transports the airflow required for drying, and at the same time, the air supply device can choose to transport hot air, which can further improve the drying effect. The airflow enters the airflow distribution box 61 to ensure the uniform distribution of the airflow. When the pressure in the airflow distribution box 61 gradually increases, the high-temperature and low-humidity airflow directly acts on the surface of the calcium carbonate, and by increasing the temperature of the calcium carbonate surface and reducing the humidity, the moisture inside the calcium carbonate is rapidly diffused to the surface and evaporated, and the generated moisture is collected by the air outlet duct network 64 and extracted out of the device by the dehumidification fan 65.

[0022] Reference Figure 1-3 , wherein the air inlet pipe network 63 and the air outlet pipe network 64 are arranged in an interlaced manner;

[0023] Through the above-mentioned structural setting, when the dry airflow is blown toward the surface of calcium carbonate through the air inlet duct network 63, it exchanges heat and mass with the calcium carbonate, absorbs the moisture in the calcium carbonate and heats the calcium carbonate, so that the moisture in the calcium carbonate evaporates. The evaporated moisture continues to flow with the airflow and is finally captured by the air outlet duct network 64 below. The staggered layout of the air inlet duct network 63 and the air outlet duct network 64 helps to maximize the contact area between the airflow and the calcium carbonate, thereby improving the drying efficiency.

[0024] Reference Figure 1-3 , wherein the protective layer 7 includes windshield plates 71 arranged at the top and bottom of the frame 1, heat-resistant plates 72 are arranged on both sides of the frame 1, and the heat-resistant plates 72 are provided with perforations 73 adapted to the first conveyor belt 3;

[0025] Through the above-mentioned structural arrangement, the wind shield 71 and the heat resistance plate 72 cooperate with each other to reduce external interference and heat loss, thereby creating a stable, efficient and energy-saving working environment inside the drying device.

[0026] Reference Figure 1-3 , wherein the material transfer assembly 8 includes a transverse moving platform 81, which is arranged on the frame 1, and a vertical moving platform 82 is arranged at the moving end of the transverse moving platform 81, and a connecting plate 83 adapted to the perforation 73 is fixedly installed at the moving end of the vertical moving platform 82, and an elastic member 84 is arranged on the connecting plate 83, which is used to vibrate the calcium carbonate and adjust the windward surface of the calcium carbonate;

[0027] Through the above-mentioned structural setting, the horizontal moving platform 81 and the vertical moving platform 82 adopt existing technology and can be purchased directly from the market. They are both composed of a screw motor, a screw, a screw nut and a guide rod. Through the cooperation between the horizontal moving platform 81 and the vertical moving platform 82, the material tray 5 on the first conveyor belt 3 can be transferred to the second conveyor belt 4.

[0028] Reference Figure 1-3 , wherein the elastic member 84 includes a telescopic rod 841, and the four corners of the connecting plate 83 are provided with the telescopic rod 841, and the telescopic ends of the four telescopic rods 841 are fixedly connected to the supporting plate 842, and a spring 843 located on the outside of the telescopic rod 841 is fixedly installed between the supporting plate 842 and the connecting plate 83, and a vibration motor 844 is fixedly installed on the surface of one side of the supporting plate 842 close to the connecting plate 83;

[0029] Through the above-mentioned structural setting, the vibration motor 844 is the driving source, and the vibration generated is transmitted to the support plate 842 through the spring 843 and the telescopic rod 841, thereby vibrating and turning the calcium carbonate over, thereby changing the windward side of the calcium carbonate and further increasing the drying effect of the calcium carbonate.

[0030] Reference Figure 1-3, wherein the material tray 5 is provided with a plurality of air outlet holes 9 which are evenly distributed;

[0031] When the dry airflow is blown toward the surface of the material through the air inlet duct 63 through the above-mentioned structure, part of the airflow will penetrate the material layer and continue to flow downward. The air outlet holes 9 set on the material tray 5 provide a channel for these airflows, so that the airflow can be evenly distributed under the material, further promoting the discharge of moisture inside the material.
