Abstract
Description
Technical Field
[0001] This utility model relates to the field of drying viscous and wet mineral products, specifically to a drying device for viscous and wet mineral products. Background Technology
[0002] Viscous mineral products refer to those mineral products that are sticky and have a high water content, and their characteristics are as follows:
[0003] Stickiness: These minerals exhibit strong stickiness due to their physicochemical properties or certain components. This can cause the minerals to easily adhere to equipment, containers, or transport vehicles during mining, transportation, and processing, increasing operational difficulties.
[0004] High humidity: Sticky mineral products typically contain a large amount of moisture, which is a characteristic of their "wetness". High humidity not only affects the quality and performance of mineral products, but may also cause a series of problems during storage and transportation, such as mold and clumping.
[0005] Common types include
[0006] Some metallic ores, such as copper ores and lead-zinc ores containing clay minerals, are often found in a sticky and wet state when mined. The clay minerals in these ores have strong water absorption and stickiness, which makes the ores exhibit sticky and wet characteristics overall.
[0007] Non-metallic minerals, such as kaolin and bentonite, have high water content and viscosity. Kaolin is commonly used in industries like ceramics and papermaking, and its sticky and wet properties require special handling during processing. Bentonite, on the other hand, is known for its excellent water absorption and swelling properties, and is widely used in drilling mud and building waterproofing, but its sticky and wet state also presents certain challenges to its processing and use.
[0008] With the development and utilization of mineral resources, the processing of sticky and moist mineral products is becoming increasingly crucial. These mineral products, due to their high viscosity and moisture content, face numerous challenges in the drying process. Currently, traditional drying equipment for sticky and moist mineral products has significant shortcomings. Firstly, many drying devices lack a hot-cold air neutralization function. If only hot air is used during the drying process, the sticky and moist mineral products are sensitive to temperature; excessively high temperatures can cause the surface of the mineral to dry rapidly, forming a hard shell that hinders internal moisture evaporation, reduces drying efficiency, and may even alter the physicochemical properties of the mineral, affecting product quality. Conversely, if the temperature is too low, the moisture evaporation requirements cannot be met, prolonging the drying time. Secondly, existing drying equipment often neglects dust extraction. During the drying process of sticky and moist mineral products, the evaporation of surface moisture causes the dust trapped within to be stirred up. This dust not only causes secondary pollution to the mineral products, reducing their cleanliness and quality, but also permeates the workshop environment, endangering the health of operators and posing safety hazards such as dust explosions. Furthermore, some drying devices have a single air outlet method, making it difficult to achieve comprehensive and uniform drying of the mineral products. Therefore, there is an urgent need to design a drying device for sticky and wet mineral products that can neutralize hot and cold air, efficiently absorb dust, and provide air outlets from multiple angles, in order to improve drying effect and product quality, and ensure production safety and environmental protection requirements. Utility Model Content
[0009] Therefore, in order to overcome the above-mentioned shortcomings, this utility model provides a drying device for sticky and wet mineral products, which is a drying device for sticky and wet mineral products with the functions of neutralizing hot and cold air, efficient dust collection and multi-angle air outlet, so as to improve the drying effect and product quality, and ensure production safety and environmental protection requirements.
[0010] This utility model is implemented by constructing a drying device for sticky and wet mineral products, characterized in that: the drying device comprises a drying section with a hot and cold air neutralization function and a dust collection section located after the drying section;
[0011] It also includes a mesh conveyor system for mineral products that traverses the drying and dust collection sections horizontally.
[0012] The drying section has a hot air outlet pipe and a cold air outlet pipe inside its cavity. There are multiple sets of hot air outlet pipes and cold air outlet pipes, which are arranged alternately. A cold air fan and a hot air outlet device are installed in the back area of the drying section. The cold air fan is used to connect with the cold air outlet pipe, and the hot air outlet device is used to connect with the hot air outlet pipe.
[0013] Furthermore, a dust collection mechanism is installed in the back area of the dust collection section. The dust collection mechanism is connected to the top of the dust collection section via a dust collection pipe. It is used to adsorb the dust generated during the drying process, so as to avoid secondary pollution of the mineral products by the dust and ensure the cleanliness and quality of the products.
[0014] Furthermore, the hot air duct and the cold air duct are both metal bends of the same specifications, and air nozzles are installed at the upper, side and bottom ends of the metal bends, so that they can discharge air to the mineral product mesh conveying mechanism in multiple directions and angles from top to bottom, side and bottom to top.
[0015] Furthermore, curtains are installed at the inlet of the drying section and at the outlet of the dust extraction section.
[0016] This utility model has the following advantages: This sticky and moist mineral product drying device improves upon the shortcomings of traditional drying equipment, possessing significant advantages in functionality and practicality. Specific beneficial effects are as follows: High-efficiency and precise drying: The drying section is equipped with multiple sets of alternating hot and cold air ducts, along with a cold air blower and a hot air device, allowing for the neutralization of hot and cold air as needed. The drying temperature can be flexibly adjusted, avoiding the problem of surface crusting due to excessively high temperatures or low drying efficiency due to excessively low temperatures, ensuring sufficient evaporation of internal moisture and improving drying efficiency and quality. Simultaneously, the hot and cold air ducts are made of metal bends, with air nozzles installed at their upper, side, and bottom ends, enabling airflow from multiple directions and angles, ensuring uniform heating of all parts of the mineral product and further optimizing the drying effect. Ensuring product cleanliness: The dust collection section is equipped with a dust collection mechanism connected to the top via a dust collection pipe, which can promptly absorb dust generated during the drying process, preventing secondary pollution of the mineral product and effectively ensuring product cleanliness and quality, thus enhancing product market competitiveness. Optimized equipment design: Curtains are installed at the inlet of the drying section and the outlet of the dust extraction section to effectively prevent the overflow of hot air and dust. This reduces heat loss and energy consumption, while also preventing dust from spreading into the workshop environment, improving the working environment, protecting the health of operators, and reducing safety hazards such as dust explosions. Furthermore, the device has a rational structural layout, with the hot and cold air system, dust extraction system, and mineral product mesh conveyor working in tandem to ensure a smooth and efficient drying process.

[0018] Figure 2 This is a schematic diagram of the internal structure of this device. Detailed Implementation
[0019] The following will be combined with the appendix Figures 1-2 This utility model will be described in detail, and the technical solutions in the embodiments of this utility model will be clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.
[0020] This utility model provides a drying device for viscous and wet mineral products, such as... Figures 1-2 As shown, it can be implemented in the following manner; the drying device consists of a drying section 100 with a hot and cold air neutralization function and a dust collection section 200 located after the drying section 100;
[0021] It also includes a mineral product mesh conveying mechanism 1 that horizontally traverses the drying section 100 and the dust collection section 200 (it should be noted that the mesh conveying mechanism can be an existing conveying mechanism, such as including a motor, a drive roller, a driven roller and a conveyor belt. The mesh size of the conveyor belt is smaller than the particle size of the mineral product. The conveyor belt is tensioned between the drive roller and the driven roller, and the motor drives the conveyor belt to move).
[0022] The drying section 100 has multiple sets of hot air ducts 2 and cold air ducts 3 arranged alternately within its inner cavity. A cold air fan and a hot air outlet device are installed on the back side of the drying section 100. The cold air fan is connected to the cold air duct 3, and the hot air outlet device is connected to the hot air duct 2. In practical implementation, the amount of temperature neutralization can be controlled according to different types of mineral products. Each duct can be equipped with a set of solenoid valves.
[0023] In this application, a dust collection mechanism 4 is installed in the back area of the dust collection section 200. The dust collection mechanism 4 is connected to the top of the dust collection section 200 via a dust collection pipe 5. It is used to adsorb the dust generated during the drying process, so as to avoid secondary pollution of the mineral products by the dust and ensure the cleanliness and quality of the products.
[0024] In this application, the hot air duct 2 and the cold air duct 3 are metal bends of the same specifications, and air nozzles are installed at the upper end, side and bottom of the metal bends, so that they can discharge air to the mineral product mesh conveying mechanism 1 in multiple directions and angles from top to bottom, side and bottom to top.
[0025] In this application, curtains 7 are installed at the inlet of the drying section 100 and the outlet of the dust extraction section 200, respectively.
[0026] For sticky and moist mineral products, the drying process usually requires the neutralization of hot and cold air, and the benefits and reasons are as follows:
[0027] Preventing surface crust formation: In the initial drying stage of sticky mineral products, if high-temperature hot air is used directly, the surface moisture will evaporate rapidly, leading to the formation of a hard crust. This hinders further evaporation of internal moisture, reduces drying efficiency, and may even prevent complete removal of internal moisture, affecting product quality. Neutralizing hot and cold air and lowering the hot air temperature allows the surface moisture of the mineral products to evaporate slowly, preventing crust formation and ensuring a smooth drying process.
[0028] To avoid increased viscosity: Sticky mineral products may become even stickier when heated. Excessive hot air temperature can make the minerals too viscous, causing them to adhere to the inner walls and components of the drying equipment. This not only affects the drying effect but also increases the difficulty of cleaning and may even lead to equipment malfunction. Neutralizing hot and cold air can control the temperature within a suitable range, reducing the degree of viscosity increase and lowering the probability of adhesion problems.
[0029] Ensuring uniform drying: The moisture distribution of viscous mineral products is often uneven, and due to their sticky nature, localized overheating or overdrying can easily occur during the drying process. Neutralizing hot and cold air helps optimize the distribution of airflow and temperature field during drying, resulting in more uniform heating of all parts of the mineral product. This improves the uniformity and consistency of drying, ensuring the stability of product quality.
[0030] Improving drying efficiency: While sticky mineral products require higher temperatures to remove moisture, excessively high temperatures can reduce drying efficiency due to the aforementioned issues. By neutralizing hot and cold air and controlling the temperature within the optimal range, moisture can be fully evaporated within a reasonable time, while avoiding prolonged drying time caused by surface crusting and increased stickiness, thereby improving overall drying efficiency.
[0031] Mineral products typically require dust extraction during the drying process, and the specific benefits are:
[0032] Environmental compliance: With increasingly stringent environmental standards, dust emissions from industrial production are subject to strict regulation. Dust generated during mineral drying, if emitted directly without treatment, will pollute the surrounding environment, leading to a decline in air quality and impacting the local ecosystem and residents' lives. Installing dust collection equipment can effectively collect dust, ensuring emissions meet environmental standards and preventing companies from facing fines, production shutdowns, or other penalties for failing to meet environmental standards.
[0033] Reduce material loss: The dust generated during the drying process is actually fine particles of mineral products. The dust collection system can collect this dust and prevent it from being lost with the airflow, thereby reducing material loss, improving the recovery rate of mineral products, and reducing production costs.
[0034] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
