Description

Technical Field

[0001] This utility model relates to the technical field of glass manufacturing, and specifically to a glass electric melting furnace. Background Technology

[0002] In modern glass manufacturing, electric glass melting furnaces are devices that use electricity as a heat source to melt glass raw materials. Their working principle is based on the conversion of electrical energy into thermal energy, using different heating methods to melt the glass raw materials and meet process requirements. As a core production piece in modern glass manufacturing, the electric glass melting furnace plays a crucial role in melting glass raw materials into a homogeneous molten glass. The quality, performance, and production efficiency of glass products largely depend on the precision of temperature control within the electric melting furnace. Traditional electric melting furnace temperature control relies heavily on operator experience and manual adjustment. Operators need to frequently observe the temperature gauges on the furnace and manually adjust the transformer settings or control the heating element switches based on the displayed temperature data.

[0003] This method has significant drawbacks: Firstly, operators cannot guarantee precise monitoring at all times, nor can they automatically control the temperature. The delay in manual judgment and operation can lead to large temperature fluctuations and an inability to respond promptly to temperature changes, easily resulting in underheating or overheating. In glass manufacturing, excessively low temperatures can cause incomplete melting of the glass raw materials, producing defects such as bubbles and impurities; excessively high temperatures can cause the glass melt components to volatilize and deteriorate, affecting the optical and physical properties of the glass products. Secondly, prolonged manual operation can easily lead to operator fatigue, increasing the risk of operational errors, reducing the stability and reliability of production, and making it difficult to meet the requirements of large-scale industrial production for product quality and production efficiency. Utility Model Content

[0004] The present invention aims to provide a glass electric melting furnace to solve the technical problems that traditional electric melting furnaces rely heavily on the experience and manual adjustment of operators for temperature control, which easily leads to insufficient or excessive heating and thus produces defective products. In addition, manual operation results in low production efficiency, making it difficult to meet the requirements of large-scale industrial production for product quality and production efficiency.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] 1) A glass electric melting furnace, comprising a base, on which a furnace body with a regular octagonal cross-section is stacked and constructed. A feeding port is reserved at the top of the furnace body, and a cover plate is provided at the top of the feeding port.

A rectangular liquid outlet is provided in the lower middle part of one side of the furnace body, and a discharge channel is constructed extending outside the liquid outlet. A heating element is provided at the top of the discharge channel. A slag outlet is provided at the lower part of the other side of the furnace body. An insulation layer is wrapped around the outer surface of the furnace body, and three temperature sensors are provided outside the insulation layer. The furnace body also includes a microprocessor, and the temperature sensors, heating elements, and electrodes are all electrically connected to the microprocessor. In this invention, a furnace body with a regular octagonal cross-section is stacked on top of the base. This shape helps to evenly distribute the internal heat and pressure. A feeding port is reserved at the top of the furnace body and equipped with a cover plate to facilitate the feeding of glass production raw materials into the furnace. The cover plate can prevent heat loss and dust and debris from entering the furnace. Electrode holes are provided at the center of each of the eight sides of the furnace body, and electrodes are installed in the electrode holes. The multi-electrode design can make the electric field distribution in the furnace more uniform, ensuring that the glass raw materials are heated evenly in the furnace and improving the efficiency of glass melting.

[0007] A rectangular outlet is located on the lower middle part of one side of the furnace body for the glass melt to flow out. An externally extended discharge channel guides the glass melt to flow smoothly out of the furnace body, facilitating subsequent processing and forming. A heating element is installed at the top of the discharge channel to heat the glass melt inside, preventing it from cooling and solidifying within the channel and ensuring smooth discharge. A slag outlet is located at the lower part of the other side to facilitate the cleaning of impurities and waste generated during the production process inside the furnace, ensuring the cleanliness of the glass melt flowing out of the furnace body and guaranteeing the quality of glass production. The furnace body is covered with an insulation layer to effectively reduce heat loss from the furnace to the outside and reduce energy consumption. Three temperature sensors are installed outside the insulation layer to monitor the temperature at different locations on the furnace body surface in real time. The furnace also includes a microprocessor. The temperature sensors, heating elements, and electrodes are all electrically connected to the microprocessor. The microprocessor receives signals from the temperature sensors, infers the temperature inside the furnace based on the received temperature data outside the insulation layer, compares it with the set temperature parameters, and intelligently adjusts the power of the electrodes to achieve precise temperature control inside the furnace. Furthermore, the microprocessor can control the operating status of the heating elements in the discharge channel, ensuring that the temperature parameters of the molten glass after it flows out meet the requirements of the next production process.

The threaded connection has the characteristics of simple structure, convenient disassembly, and reliable connection, facilitating the installation, replacement, and maintenance of the electrode 4.

[0038] Because electrode 4 is securely installed in electrode hole 3 via fixing post 5, electrical faults or unstable operation of the glass electric melting furnace caused by loosening or displacement of electrode 4 can be effectively avoided during long-term operation. This greatly enhances the overall reliability and stability of the glass electric melting furnace, ensuring the continuity of the glass production process and the stability of product quality. The convenient installation and removal of electrode 4 allows maintenance personnel to inspect, replace, and maintain electrode 4 more efficiently, reducing the manpower and material resources consumed due to complex maintenance operations and lowering the risk of damage to other components during maintenance, thereby effectively reducing the overall maintenance cost of the equipment. Threaded holes are provided in the furnace body 2 corresponding to the through holes, and fixing post 5 is fixed to the outside of furnace body 2 by passing through the through holes and threaded holes sequentially with high-temperature resistant bolts.

Simultaneously, the furnace body 2 has threaded holes at the corresponding through holes. High-temperature resistant bolts are then passed through the through holes of the fixing column 5 and the threaded holes of the furnace body 2, firmly fixing the fixing column 5 to the outside of the furnace body 2. This bolted connection structure, combined with the precise correspondence between the through holes and the threaded holes, forms a stable mechanical connection. The reliable fixing method of the fixing column 5 reduces the risk of equipment wear and failure due to loose connections or component displacement. The high-temperature resistant bolts maintain good tightening performance under high-temperature environments, preventing damage to other components caused by connection failures, reducing equipment maintenance frequency, effectively extending the overall service life of the glass electric melting furnace, and reducing equipment replacement costs.

[0039] In this invention, a rectangular high-temperature resistant silicon carbide filter screen is provided on the side of the glass electric melting furnace outlet 14 opposite to the discharge channel 8. Its size is precisely matched with the outlet 14 to ensure complete coverage of the outlet 14. High-temperature resistant hooks are arranged around the outlet 14, and through holes matching the size of the hooks are provided around the filter screen. The filter screen is initially fixed to the outlet 14 by passing the hooks through the through holes. In addition, high-temperature sealant is applied around the filter screen to further enhance the sealing effect, forming a double fixing and sealing structure.

[0040] By intercepting impurities in the molten glass through a filter, the probability of impurities and defects in glass products is significantly reduced, resulting in glass products with higher transparency and purity, thus improving product quality. Effective filtration reduces wear on the discharge channel 8 and subsequent forming equipment, lowering equipment maintenance costs and repair frequency. The application of high-temperature resistant materials ensures the long-term stable operation of the filtration system itself in high-temperature environments, avoiding frequent replacement of filter screens and related components due to material failure, thereby extending the overall service life of the glass electric melting furnace. A valve is installed near the liquid outlet 14 in the discharge channel 8. The valve includes a valve plate and a valve stem. The valve plate has a second internal thread hole, and one end of the valve stem has a second external thread that matches the second internal thread hole. The valve stem is screwed into the valve plate and connected to a hydraulic drive device.

[0041] In this invention, a valve is installed in the discharge channel 8 of the glass electric melting furnace near the liquid outlet 14. The valve consists of a valve plate and a valve stem. The valve plate has a second internal thread hole, and one end of the valve stem has a matching second external thread. The valve stem and the valve plate are connected by thread engagement. This threaded connection method facilitates the installation, disassembly, and adjustment of the valve stem and the valve plate. At the same time, the valve stem is connected to a hydraulic drive device, and the power of the hydraulic system is used to drive the movement of the valve stem, thereby controlling the opening and closing of the valve plate.

[0042] Controlling the flow rate of molten glass helps improve the dimensional accuracy of glass products during the forming process, effectively reduces the scrap rate caused by improper flow control, improves the overall quality of glass products, and enhances the market competitiveness of enterprise products. The remote operation mode driven by hydraulics eliminates the need for operators to manually adjust valves near the high-temperature, dangerous furnace, reducing the safety risks such as burns. Simultaneously, rapid and precise valve control can quickly respond to changes in the production process, reducing waiting time, improving production efficiency, and lowering labor costs. It also includes a first high-temperature resistant bracket 11, through which the hydraulic drive device is fixed above the discharge channel 8. The first high-temperature resistant bracket 11 is fixed to the base 1 near the discharge channel 8 by high-temperature resistant bolts. The hydraulic drive device includes a hydraulic cylinder 12 and a hydraulic rod, with the hydraulic rod hinged to the valve stem. The hydraulic cylinder 12 is electrically connected to the microprocessor.

[0043] In this invention, the first high-temperature resistant bracket 11 is used to fix the hydraulic drive device. The first high-temperature resistant bracket 11 is connected to the base 1 near the discharge channel 8 by high-temperature resistant bolts. The first high-temperature resistant bracket 11 is connected to the hydraulic drive device by a clamp. The hydraulic drive device is vertically fixed above the discharge channel 8, with its extended end facing the discharge channel 8. The hydraulic drive device consists of a hydraulic cylinder 12 and a hydraulic rod. The hydraulic rod and the valve stem are connected by a hinge. The hinge structure allows the hydraulic rod to flexibly drive the valve stem to move when transmitting power, adapting to the working requirements of the valve stem at different opening and closing angles, and ensuring the flexibility of valve control. The application of high-temperature resistant brackets and bolts ensures the stability of the hydraulic drive device in high-temperature environments, preventing structural damage and performance degradation caused by high temperatures. This effectively extends the service life of the hydraulic drive device, reduces equipment failure frequency, ensures long-term stable operation of the glass electric melting furnace, and lowers downtime maintenance costs. The connection between the microprocessor and the hydraulic cylinder 12 enables precise control of valve opening and closing, allowing adjustment of the glass melt flow rate according to different production process requirements. This not only improves the dimensional accuracy and quality of glass products but also meets diverse production needs, enhancing the company's competitiveness in the glass manufacturing market. The system also includes three second high-temperature resistant brackets 13. Three high-temperature infrared thermometers 10 are used as sensors, each corresponding to one of the three second high-temperature resistant brackets 13. Each high-temperature infrared thermometer 10 is equipped with a water-cooling jacket. The three second high-temperature resistant brackets 13 are evenly distributed on the upper surface of the base 1 and fixed to the upper part of the base 1 with high-temperature resistant bolts.

[0044] This invention features three second high-temperature resistant supports 13, evenly distributed on the upper surface of the glass electric melting furnace base 1. These supports are securely connected to the upper part of the base 1 using high-temperature resistant bolts, ensuring installation stability under high-temperature conditions. Three high-temperature infrared thermometers 10 are used as sensors, each corresponding to one of the three second high-temperature resistant supports 13, forming a multi-point temperature measurement layout that comprehensively monitors the temperature in different areas of the furnace. Each high-temperature infrared thermometer 10 is equipped with a water-cooling jacket. The water-cooling jacket uses circulating cooling water to remove the heat absorbed by the thermometer during operation, providing cooling protection and ensuring that the infrared thermometer maintains normal operating performance and measurement accuracy even under high-temperature conditions. The multi-point temperature measurement layout can comprehensively reflect the temperature field distribution inside the furnace. Operators can adjust the heating power of the glass electric melting furnace in a timely and accurate manner based on this temperature data to ensure that the glass production process is carried out under optimal temperature conditions, thereby improving the quality and production efficiency of glass products and reducing the scrap rate. The sturdy second high-temperature resistant bracket 13 installation structure reduces the risk of damage to the temperature measuring equipment caused by vibration, high temperature and other factors. The water-cooled jacket protects the temperature measuring instrument from heat dissipation, avoiding performance degradation and component aging caused by overheating, and reducing equipment maintenance and replacement costs.

[0045] The second high-temperature resistant bracket 13 adopts an adjustable telescopic rod, which includes an inner sleeve, an outer sleeve, and a wing screw 16. The inner sleeve is nested in the outer sleeve and can slide up and down along the height direction inside the outer sleeve. An opening is provided at the upper part of the outer sleeve, and a nut for the wing screw 16 to pass through is fixed in the opening. After the wing screw 16 passes through the nut, it abuts against the outer surface of the inner sleeve. The second high-temperature resistant bracket 13 adopts an adjustable telescopic rod structure. This telescopic rod consists of an inner sleeve, an outer sleeve, and a wing screw 16. The inner sleeve is nested within the outer sleeve, forming a relatively sliding sleeve structure. This design provides the basis for height adjustment. An opening is provided at the top of the outer sleeve, and a nut is fixed inside the opening to cooperate with the wing screw 16 for fixing. The inner sleeve can slide freely along the height direction within the outer sleeve. By sliding the inner sleeve, the overall height of the telescopic rod can be changed. The wing screw 16 passes through the nut in the opening of the outer sleeve. When the wing screw 16 is tightened, its end can abut against the outer surface of the inner sleeve. By tightening or loosening the wing screw 16, the position of the inner sleeve can be locked or unlocked, thereby precisely adjusting the height of the telescopic rod. This allows the high-temperature resistant infrared thermometer to measure temperatures at different heights to ensure the accuracy of the measurement results.
