Description

Technical Field

[0001] This utility model relates to the field of electrofused white fused alumina cooling and dust removal technology, specifically an electrofused white fused alumina cooling and dust removal device. Background Technology

[0002] In the production process of fused white fused alumina, the high-temperature molten white fused alumina material is produced from equipment such as electric arc furnaces at extremely high temperatures. If this high-temperature material is not cooled in time, it will not only be difficult to directly enter subsequent processing steps such as crushing and screening, but may also damage subsequent processing equipment due to excessive temperature, affecting the normal operation and service life of the equipment. At the same time, the high-temperature material also needs to reach suitable temperature conditions during storage to avoid deterioration or other conditions that are detrimental to product quality. Therefore, effective cooling of high-temperature fused white fused alumina material is a key link to ensure production continuity and product quality stability.

[0003] On the other hand, the production process of fused white fused alumina generates a large amount of dust-laden waste gas. This waste gas contains various fine particulate matter, such as unreacted raw material powder and impurities generated during the production process. If this dust-laden waste gas is directly discharged into the atmosphere without treatment, the particulate matter will remain suspended in the air for a long time, leading to a decline in air quality, the formation of smog and other severe weather phenomena, and serious damage to the surrounding ecological environment, affecting the survival and growth of plants and animals. In addition, the harmful substances in this waste gas may also spread to residential areas with air currents, posing a threat to human health and causing various health problems such as respiratory diseases and cardiovascular diseases. Moreover, with increasingly stringent environmental regulations, enterprises must take effective measures to treat the dust-laden waste gas generated during the production process to meet environmental protection requirements and avoid facing risks such as high fines and production shutdowns. Therefore, how to efficiently remove particulate matter from the dust-laden waste gas generated during the production process of fused white fused alumina and achieve emission standards is an important problem that fused white fused alumina production enterprises must solve.

[0004] Currently, although there are various cooling and dust removal devices in the industrial field, most of these devices are designed for general industrial production. The devices designed for the specific production process of fused white corundum are significantly inadequate in terms of functional adaptability and performance.

[0005] Some traditional cooling equipment may use simple air cooling or water cooling methods. Air cooling equipment may have the problem of low cooling efficiency. For high-temperature fused white corundum materials, relying solely on natural air convection or simple fan blowing is difficult to reduce the material temperature to a suitable range in a short time, resulting in a longer production cycle and reduced production efficiency. Moreover, air cooling may not be able to reduce the material temperature evenly, causing the material temperature to be too high or too low in some areas, which affects the quality stability of the product.

[0006] Therefore, we propose an electrofused white corundum cooling and dust removal device to solve the above-mentioned problems. Utility Model Content

[0007] To address the shortcomings of existing technologies, this invention provides an electrofused white corundum cooling and dust removal device to solve the problems mentioned in the background section.

[0021] 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.

[0022] Example 1: Please refer to Figure 1 , Figure 2 and Figure 3A cooling and dust removal device for fused white corundum includes a cooling and dust removal mechanism and a bag filter 3. The cooling and dust removal mechanism includes a cooling and dust removal box 1, a cooling fan 101 and a water pipe 106. The cooling and dust removal box 1 is welded from sturdy and durable steel. Its top is fixed with a top cover 105 by bolts. The top cover 105 is made of stainless steel and has good corrosion resistance.

[0023] Multiple water pipes 106 are evenly welded on both inner walls of the top cover 105. These water pipes 106 are interconnected through connecting pipes 108 to form a complete water system. Multiple spray heads 107 are evenly installed at the bottom of the water pipes 106. The spray heads 107 are installed at an angle, which can be set to 45°. This design can make the sprayed water mist cover a wider range, or it can be set according to the actual situation to make full contact with high-temperature materials such as fused white corundum to improve the cooling effect. A connecting water pipe 103 extending to the outside of the top cover 105 is installed in the middle of the connecting pipe 108. The connecting water pipe 103 is made of pressure-resistant and corrosion-resistant hose to facilitate connection with external water sources and provide a stable water source for the spray heads 107.

[0024] Mounting holes are provided on both side walls of the cooling dust removal box 1. The cooling fan 101 is fixedly installed in the mounting holes by bolts. The cooling fan 101 is a high-power, low-noise axial flow fan, which can quickly draw external cold air into the cooling dust removal box 1. A dustproof net is installed at the air inlet of the cooling fan 101. The dustproof net is made of fine metal wire mesh, which can effectively block external dust and impurities from entering the cooling dust removal box 1 and prevent impurities from being mixed into the fused white corundum. A connecting air duct 102 extending into the interior of the cooling fan 101 is installed on the upper part of the cooling fan 101. One end of the connecting air duct 102 can be connected to the cold air, so that the cooling fan 101 can draw cold air and distribute it evenly in the cooling dust removal box 1.

[0025] The top cover 105 is designed in an inverted bucket shape, which is conducive to collecting water vapor and dust generated during the cooling process. At the center of the top of the top cover 105, a dust suction pipe 301 is fixedly installed through the top cover 105 by welding. The other end of the dust suction pipe 301 is connected to the dust inlet end of the bag dust collector 3 through a flange. A negative pressure fan is installed inside the bag dust collector 3, which can suck the dust and water vapor in the cooling dust collection box 1 into the bag dust collector 3 through the dust suction pipe 301. The bag dust collector 3 adopts efficient pulse bag dust collection technology, which can effectively remove particulate matter in dusty exhaust gas and achieve emission standards.

[0026] Inside the cooling dust removal box 1, a guide rail 104 extending to the outside of the cooling dust removal box 1 is installed. The guide rail 104 is made of high-strength I-beam steel and the surface is treated with anti-rust. A receiving cart 2 is installed on the guide rail 104. The bottom of the receiving cart 2 is equipped with rollers that are compatible with the guide rail 104, allowing it to slide freely on the guide rail 104. A handle 201 is installed on the receiving cart 2. The handle 201 is made of bent steel pipe and the surface is covered with an anti-slip rubber sleeve, making it convenient for operators to push the receiving cart 2 in and out of the cooling dust removal box 1.

[0027] In actual use, the high-temperature fused white corundum material is placed on the receiving cart 2, and the receiving cart 2 is pushed into the cooling and dust removal box 1. The cooling fan 101 and the external water source are turned on. The cooling fan 101 draws in the external cold air into the cooling and dust removal box 1, while the water spray head 107 sprays water mist to cool the high-temperature material. The water vapor and dust generated during the cooling process are drawn into the bag filter 3 for treatment under the action of the suction pipe 301, thereby achieving the dual purpose of cooling and dust removal.

[0028] Example 2: Please refer to Figure 1 , Figure 2 and Figure 3 The overall structure of the electrofused white corundum cooling and dust removal device in this embodiment is similar to that in Embodiment 1, but some details have been optimized. The material of the cooling and dust removal box 1 is made of higher grade alloy steel, which has better high temperature resistance and corrosion resistance, and can adapt to harsher production environments.

[0029] The layout of the water pipes 106 and the spray nozzles 107 has been adjusted, increasing the number of water pipes 106 and the density of spray nozzles 107, resulting in a wider spray range and more uniform cooling effect. The tilt angle of the spray nozzles 107 has been adjusted to 30°, further optimizing the coverage of the water mist. A new type of flexible hose with better flexibility and pressure resistance has been selected for the connecting water pipes 103, which can better adapt to the vibration and movement of the equipment.

[0030] The cooling fan 101 adopts intelligent frequency conversion control technology, which can automatically adjust the fan speed according to the temperature and pressure inside the cooling dust removal box 1, so as to reduce energy consumption while ensuring the cooling effect. The dust filter adopts a detachable design, which is convenient for regular cleaning and replacement to ensure the dust prevention effect.

[0031] The surface of the guide rail 104 has undergone special lubrication treatment, which reduces the friction of the receiving cart 2 during movement, making operation easier. The body of the receiving cart 2 adopts a lightweight design, while increasing the load capacity and improving the efficiency of the equipment. An electronic display screen is installed on the handle 201, which can display information such as the position of the receiving cart 2 and the temperature inside the cooling dust removal box 1 in real time, making it convenient for operators to monitor and manage.

[0032] During operation, when high-temperature materials enter the cooling and dust removal box 1, the intelligent variable frequency cooling fan 101 automatically adjusts its speed according to the preset temperature parameters, and works with the increased density water spray head 107 to achieve efficient cooling. The detachable dustproof net can clean the dust in time to ensure the normal operation of the fan. The operator can monitor the equipment's operating status in real time through the electronic display screen on the handle 201 and adjust the operating parameters in time to ensure that the cooling and dust removal process is carried out efficiently and stably.

[0033] Example 3: Please refer to Figure 1 , Figure 2 and Figure 3 Based on Embodiment 1 and Embodiment 2, the electrofused white corundum cooling and dust removal device of this embodiment further integrates an automated control system. Multiple temperature sensors and pressure sensors are installed in the cooling and dust removal box 1, and these sensors are connected to the central controller via data cables.

[0034] The temperature sensor can monitor the temperature change inside the cooling dust removal box 1 in real time and transmit the data to the central controller. When the temperature exceeds the set upper limit, the central controller will automatically increase the speed of the cooling fan 101 and the water flow of the spray head 107 to speed up the cooling. When the temperature is lower than the set lower limit, the central controller will automatically reduce the speed of the cooling fan 101 and the water flow of the spray head 107 to save energy.

[0035] The pressure sensor is used to monitor the pressure inside the cooling dust removal box 1, ensuring that the equipment operates within a safe working pressure range. If the pressure is abnormal, the central controller will issue an alarm signal to remind the operator to handle the situation promptly.

[0036] The bag filter 3 is also connected to the central controller, realizing the automatic dust removal function. When the pressure difference inside the bag filter 3 reaches the set value, the central controller will automatically start the pulse cleaning system to clean the filter bags and ensure the dust removal efficiency of the bag filter 3.

[0037] The movement of the receiving vehicle 2 is also automated. Operators can input commands through the control panel to make the receiving vehicle 2 automatically enter and exit the cooling and dust removal box 1 along the guide rail 104, reducing the labor intensity of manual operation.

[0038] In practical applications, the entire cooling and dust removal process is monitored and managed by an automated control system. Operators only need to set the relevant parameters on the control panel, and the equipment can run automatically. When an abnormal situation occurs, the system will automatically alarm and take corresponding protective measures, which greatly improves the safety and reliability of the equipment, as well as production efficiency and quality.

[0039] Implementation Results: Multiple water pipes 106 are installed on the inner walls of both sides of the top cover 105 of the cooling dust removal box 1, and multiple sets of water spray heads 107 are evenly arranged at the bottom of the water pipes 106. This layout makes the water spray range wide and can fully cover the high-temperature materials, thereby enhancing the cooling effect. The water spray heads 107 are installed at an angle, which further optimizes the spray direction of the water mist, allowing the water mist to contact the materials more evenly, accelerating the heat exchange rate, effectively shortening the cooling time of the materials, and improving production efficiency.

[0040] Cooling fans 101 are installed on both sides of the cooling dust collection box 1. With the help of connecting air ducts 102, airflow is guided, which can quickly draw cold air from outside into the box, forming good air convection, accelerating material cooling, and ensuring the stability and efficiency of the cooling process. The dust screen installed at the air inlet of the cooling fan 101 can block external dust and impurities from entering the cooling dust collection box 1, avoiding impurities in the fused white corundum. The top cover 105 is shaped like an inverted bucket, and the dust suction pipe 301 is fixedly installed at the center of the top of the top cover 105. This structure is conducive to collecting water vapor and dust generated during the cooling process. The dust-laden exhaust gas is efficiently transported to the bag filter 3 for treatment through the dust suction pipe 301, effectively removing particulate matter in the exhaust gas, reducing environmental pollution, and meeting environmental protection requirements.
