Abstract
Description
Technical Field
[0001] This utility model belongs to the field of calcium carbonate production technology, and specifically relates to a drying mechanism for calcium carbonate. Background Art
[0002] Calcium carbonate is an important inorganic compound with wide applications in many fields. The drying process of calcium carbonate is a crucial step in the preparation of dried calcium carbonate products, playing a vital role in ensuring product quality and improving production efficiency. Therefore, in current industrial production, the drying process of calcium carbonate is an indispensable step. It aims to remove moisture and other volatile substances from the calcium carbonate raw materials to obtain dried calcium carbonate products. This process typically includes pretreatment, equipment drying, and post-treatment steps. In the pretreatment stage, impurities in the raw materials are removed to ensure the purity and safety of the product. Subsequently, the raw materials are sent to the drying equipment. After drying, the raw materials undergo further processing such as screening, grading, and packaging to meet the needs of different customers.
[0003] While these methods can achieve calcium carbonate drying to some extent, they suffer from problems such as low drying efficiency, high energy consumption, and uneven drying. In addition, the drying process can easily cause agglomeration and contamination of calcium carbonate powder, which seriously affects product quality. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a drying mechanism for calcium carbonate.
[0005] To achieve the above objectives, this utility model provides a drying mechanism for calcium carbonate, including a drying cylinder. A base is fixedly connected to the bottom of the drying cylinder, a discharge port is fixedly connected to the bottom of the drying cylinder, and a feed port is fixedly connected to the top of the drying cylinder. A uniform heating component is provided inside the drying cylinder. The uniform heating component is used to evenly distribute calcium carbonate inside the drying cylinder and dry the calcium carbonate inside the drying cylinder. The uniform heating component is connected to the drying cylinder.
[0006] In the above technical solution, the uniform heating component further includes a motor fixedly connected to the top of the drying cylinder via a mounting bracket. The output end of the motor is fixedly connected to a drive shaft, which is inserted into and rotatably connected to the inside of the drying cylinder. An auger is fixedly connected to the outer wall of the drive shaft, a spiral plate is fixedly connected to the inner wall of the drying cylinder, and a heating element is connected inside the drying cylinder.
[0007] In the above technical solution, a baffle is fixedly connected to one side of the auger, and a uniformly distributed flow tube is fixedly connected to the outer wall of the auger. A flow groove adapted to and connected to the flow tube is opened on the outer wall of the auger.
[0008] In the above technical solution, the spiral plate and the auger are intersected, and the outer wall of the spiral plate is provided with uniformly distributed discharge ports, and the four adjacent spiral plates are not perpendicular to each other.
[0009] In the above technical solution, the heating element further includes uniformly distributed heating lamps inserted and fixedly connected to the outer wall of the spiral plate, and a power source is fixedly connected to the top of the drying cylinder, and the power source is electrically connected to the heating lamps.
[0010] In the above technical solution, the heating lamp tube is further encased in borosilicate glass.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. Power is supplied to the heating lamps to heat up and bake the calcium carbonate inside the drying cylinder, causing the moisture attached to the calcium carbonate to evaporate, thus drying the calcium carbonate inside. The advantage of this setting is that by directly supplying power to the heating lamps, the heat energy conversion efficiency is improved, and to a certain extent, the energy loss caused by airflow in traditional hot air drying is eliminated. At the same time, the direct heating of the heating lamps reduces energy consumption, making the baking process more energy-efficient and efficient, thereby significantly improving the quality of the dried calcium carbonate and ensuring the uniformity and stability of the product.
[0013] 2. The controller starts the motor, driving the transmission shaft and auger to rotate synchronously. The material at the bottom of the drying cylinder is continuously conveyed upwards in a spiral motion to the top. Because the baffle protrudes slightly from the auger surface, it effectively prevents material from falling off midway, ensuring a consistent upward conveying volume. This design effectively avoids the problems of low heating efficiency and uneven heating caused by material accumulation at the bottom in traditional technologies. Furthermore, some material passes through a flow channel during conveying, flowing along the flow tube under centrifugal force and distributing onto the spiral plate located below the flow tube. Multiple flow tubes evenly distribute the material onto the spiral plate, achieving uniform distribution and allowing the material to receive heat more evenly, further improving heat transfer efficiency and heating uniformity. The spiral plate is stationary, and the material flows downwards along it, falling through the discharge port to the bottom, optimizing the material's flowability on the spiral plate. When the material is on the spiral plate, it can still receive heat for baking, contributing to efficient heat transfer. Simultaneously, no power source is required, reducing energy consumption and achieving energy-efficient drying of the material. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features and advantages of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.
[0020] like Figure 1-Figure 4 The drying mechanism for calcium carbonate shown includes a drying cylinder 1, a base 3 fixedly connected to the bottom of the drying cylinder 1, a discharge port 2 fixedly connected to the bottom of the drying cylinder 1, and a feed port 4 fixedly connected to the top of the drying cylinder 1. In the above arrangement, the cross-shaped base 3 can more stably fix the drying cylinder 1. Raw materials are fed into the drying cylinder 1 through the feed port 4 and discharged from the drying cylinder 1 through the discharge port 2. The advantage of this arrangement is that it improves the overall stability of operation and optimizes the user experience.
[0021] The drying cylinder 1 is internally connected to a heating element, which includes uniformly distributed heating lamps 7 inserted and fixedly connected to the outer wall of the spiral plate 8. A power supply 5 is fixedly connected to the top of the drying cylinder 1, and the power supply 5 is electrically connected to the heating lamps 7. The heating lamps 7 are wrapped with borosilicate glass. In this setup, the power supply 5 supplies electricity to heat the heating lamps 7 and bake the calcium carbonate inside the drying cylinder 1, causing the moisture attached to the calcium carbonate to evaporate, thereby drying the calcium carbonate inside. The advantage of this setup is that by directly supplying the heating lamps 7 with the power supply 5, the heat energy conversion efficiency is improved, and to a certain extent, the energy loss caused by airflow in traditional hot air drying is eliminated. At the same time, the direct heating of the heating lamps 7 reduces energy consumption, making the baking process more energy-efficient and efficient, thereby significantly improving the quality of the dried calcium carbonate and ensuring the uniformity and stability of the product.
[0022] A uniform heating assembly is installed inside the drying cylinder 1. This assembly is used to evenly distribute calcium carbonate within the drying cylinder 1 and to dry the calcium carbonate inside. The uniform heating assembly is connected to the drying cylinder 1 and includes a motor 6 fixedly connected to the top of the drying cylinder 1 via a mounting bracket. A drive shaft 10 is fixedly connected to the output end of the motor 6, and the drive shaft 10 is inserted into and rotatably connected inside the drying cylinder 1. An auger 11 is fixedly connected to the outer wall of the drive shaft 10, and a spiral plate 8 is fixedly connected to the inner wall of the drying cylinder 1. A baffle 12 is fixedly connected to one side of the auger 11. A uniformly distributed flow tube 14 is fixedly connected to the outer wall of the auger 11. A flow groove 13, adapted to and connected to the flow tube 14, is opened on the outer wall of the auger 11. Spiral plates 8 intersect with the auger 11. A uniformly distributed feed port 9 is opened on the outer wall of the spiral plates 8, and the four adjacent spiral plates 8 are not perpendicular to each other. In this configuration, the controller starts the motor 6, driving the transmission shaft 10 and the auger 11 to rotate synchronously, spiraling upwards to continuously feed the raw material located at the bottom of the drying cylinder 1. The material is conveyed to the top. Because the baffle 12 protrudes slightly from the surface of the auger 11, it effectively prevents the material from falling off midway, thus ensuring the upward conveying volume during the process. This design effectively avoids the problems of low heating efficiency and uneven heating caused by the accumulation of material at the bottom in traditional technologies. Furthermore, some material passes through the flow channel 13 during the conveying process and flows along the flow tube 14 under the action of centrifugal force, distributing it onto the spiral plate 8 located below the flow tube 14. In this operation, multiple flow tubes 14 will evenly distribute the material onto the spiral plate 8, achieving uniform distribution of the material on the spiral plate. This allows the material to receive heat more evenly, further improving heat transfer efficiency and heating uniformity. The spiral plate 8 is in a stationary spiral shape, and the material will flow downward along the spiral plate 8. During the process, it will fall to the bottom through the discharge port 9, optimizing the flowability of the material on the spiral plate 8. When the material is on the spiral plate 8, it can also receive heat baking, which helps to efficiently transfer heat. At the same time, no power source is required, thereby reducing energy consumption and achieving energy-saving drying of the material.
[0023] The heating lamp tube 7 is wrapped with borosilicate glass, which has the advantage of better protecting the heating core inside.
[0024] Working principle:
[0025] Power supply 5 provides electricity to heat the heating lamp 7 and bake the calcium carbonate inside the drying cylinder 1, causing the moisture attached to the calcium carbonate to evaporate, thereby drying the calcium carbonate inside. The advantage of this setting is that by directly supplying power to the heating lamp 7, the heat energy conversion efficiency is improved, and to a certain extent, the energy loss caused by airflow in traditional hot air drying is eliminated. At the same time, the direct heating of the heating lamp 7 reduces energy consumption, making the baking process more energy-efficient and efficient, thereby significantly improving the quality of the dried calcium carbonate and ensuring the uniformity and stability of the product.
[0026] The controller starts the motor 6, driving the transmission shaft 10 and the auger 11 to rotate synchronously, spiraling upwards to continuously transport the raw material located at the bottom of the drying cylinder 1 to the top. Because the baffle 12 protrudes slightly from the surface of the auger 11, it effectively prevents the raw material from falling off midway, thus ensuring the upward conveying volume during the process. This design effectively avoids the problems of low heating efficiency and uneven heating caused by the accumulation of raw material at the bottom in traditional technologies. Furthermore, because some raw material passes through the flow channel 13 during the conveying process, it flows along the flow tube 14 under the action of centrifugal force and is dispersed to the screw below the flow tube 14. On the spiral plate 8, multiple flow tubes 14 evenly distribute the raw material onto the spiral plate 8 during operation, achieving uniform distribution of the raw material on the spiral plate. This allows the raw material to receive heat more evenly, further improving heat transfer efficiency and heating uniformity. The spiral plate 8 is in a stationary spiral shape, and the raw material flows downward along the spiral plate 8. During the process, it falls to the bottom through the discharge port 9, optimizing the flowability of the raw material on the spiral plate 8. When the raw material is on the spiral plate 8, it can also receive heat baking, which helps to efficiently transfer heat. At the same time, no power source is required, thereby reducing energy consumption and achieving energy-saving drying of the raw material.
