[0002] In the photovoltaic industry, photovoltaic glass uses sunlight to generate electricity, so there are extremely high requirements for the light transmittance of glass. In order to develop glass with better light transmittance, it is necessary to conduct repeated melting experiments in the laboratory. If the required raw materials are added at one time during the melting experiment, it will lead to various problems such as poor melting effect of raw materials, too long melting time, too much gas released during the solute process causing overflow, etc. In order to solve and avoid the above problems, it is necessary to add raw materials to the crucible in small amounts multiple times.

[0003] Most of the existing experimental glass melting furnaces use a side door for charging, and after opening the side door, the materials are manually added to the crucible of the glass melting furnace.

[0004] Opening the side door for charging requires a larger working space in the melting furnace. The increase in the space in the furnace will inevitably affect the rate of temperature increase in the furnace. In order to ensure the temperature in the furnace, the power of electric heating must be increased, which increases the cost of the experiment. Summary of the invention

[0005] A technical problem to be solved by the present disclosure is: how to reduce the space required in the sample melting furnace, thereby increasing the temperature rise rate in the furnace, reducing the power of electric heating, and reducing the experimental cost.

[0006] In order to solve the above technical problems, the present disclosure provides a photovoltaic glass melting furnace feeding device, comprising:

[0007] A supporting platform, with a container disposed on the top of the supporting platform, the container being used to contain materials;

[0008] The lifting mechanism is fixedly connected to the supporting platform, and the lifting mechanism can drive the supporting platform to move so that the container can move back and forth in and out of the melting furnace.

[0017] A photovoltaic glass sample melting furnace comprises the above-mentioned photovoltaic glass sample melting furnace feeding device.

[0018] A method for using a photovoltaic glass melting furnace comprises the following steps:

After the addition is completed, the support platform is driven upward by the lifting mechanism to reset, thereby sealing the furnace bottom and continuing heating. By opening the furnace bottom and bringing the container outside the furnace for heating, the working space for adding materials in the furnace body is saved, so that the required space in the furnace body can be smaller, further increasing the temperature increase speed in the furnace, reducing the power of electric heating, and thus reducing the experimental cost.

[0035] In the photovoltaic industry, photovoltaic glass uses sunlight to generate electricity, so there are extremely high requirements for the light transmittance of glass. In order to develop glass with better light transmittance, it is necessary to conduct repeated melting experiments in the laboratory.

[0036] Most of the existing experimental glass melting furnaces use a side door for charging, and after opening the side door, the materials are manually added to the crucible of the glass melting furnace.

[0037] Opening the side door for charging requires a larger working space in the melting furnace.

In order to ensure the temperature in the furnace, the power of electric heating must be increased, which increases the cost of the experiment.

[0038] In order to solve the above technical problems, the embodiment of the present disclosure provides a photovoltaic glass melting furnace feeding device, which can reduce the space required in the melting furnace, thereby increasing the temperature rising rate in the furnace, reducing the power of electric heating, and reducing experimental costs.

[0039] Example 1

[0040] A photovoltaic glass melting furnace feeding device includes a supporting platform 1 and a lifting mechanism 3. A container 2 is arranged on the top of the supporting platform 1, and the container 2 is used to contain materials. The lifting mechanism 3 is fixedly connected to the supporting platform 1, and the lifting mechanism 3 can drive the supporting platform 1 to move so that the container 2 can reciprocate inside and outside the melting furnace.

[0041] The support platform 1 is a component in the feeding device, and its main function is to carry the material container 2 and ensure that the container 2 remains stable during movement. The support platform 1 is connected to the lifting mechanism 3. By driving the lifting mechanism 3, the container 2 can be reciprocated inside and outside the melting furnace to facilitate the feeding and unloading of materials. The shape of the support platform 1 can be designed according to the specific application requirements and the shape of the material container 2. Specifically, the support platform 1 can be a rectangular platform, which is suitable for most standard-sized material containers 2. The rectangular platform has a simple structure, is easy to manufacture and install, and can provide a large bearing area. The support platform 1 can also be a circular platform, which is suitable for circular or approximately circular material containers 2. The circular platform can better adapt to the shape of the container 2 and reduce the risk of material shaking. For material containers 2 of special shapes, a customized support platform 1 can be designed. For example, some material containers 2 may have an irregular bottom shape. In this case, it is necessary to design a corresponding support platform 1 to ensure stability. The shape of the support platform 1 can also be adapted according to the shape of the bottom of the melting furnace so that the support platform can serve as the bottom plate of the melting furnace to seal the melting furnace. For example, a square opening corresponds to a square support platform 1, and a circular opening corresponds to a circular support platform 1.

[0042] According to different usage scenarios and technical requirements, the support platform 1 can be divided into several types. Specifically, the support platform 1 can be able to move up and down only through the lifting mechanism 3, which is suitable for production environments with low feeding frequency and a single type of material. It can also be a movable support platform 1, the platform part can move in the horizontal direction, and can be equipped with slide rails or rollers. For example, the middle part and other parts of the support platform 1 can be connected by slide rails or rollers so that the platform part can move in the horizontal direction, leaving the relatively high temperature area corresponding to the projection of the furnace bottom to feed, which is used for multi-station operation or production environments that require frequent adjustment of the feeding position. The support platform 1 can also be a rotating support platform 1, and the platform can rotate around the central axis to facilitate feeding operations from different angles, and is used for complex process flows that require feeding from multiple directions.

[0043] Specifically, a guide rail can be provided on the inner wall of the melting furnace, and the guide rail extends out of the bottom of the melting furnace. The support platform 1 is slidably connected to the guide rail to further improve the stability of the movement of the support platform 1. A vibrator is installed at the bottom of the platform to help the material to be evenly distributed and reduce agglomeration and bubbles. The vibrator can also be connected to the controller to adjust the vibration frequency to adapt to the characteristics of different materials. The controller can use a programmable logic controller (PLC) for automatic control to achieve remote operation and monitoring. The support platform 1 can be stainless steel, ceramic material, graphite or refractory brick, which is corrosion-resistant and high-temperature resistant, and is suitable for high-temperature environments.

[0044] Container 2 is a device for holding materials, which is made of high temperature resistant and corrosion resistant materials, can remain stable under high temperature environment, and ensure the safety and uniformity of materials during transportation and feeding. Specifically, container 2 can be a rectangular container 2, which has a simple structure, is easy to manufacture and clean, and is suitable for most solid and liquid materials, and is suitable for granular or powdered materials such as quartz sand and soda ash. Container 2 can also be a circular container 2, which has a compact structure and can reduce the dead angle of materials in container 2, facilitating the uniform distribution of materials. It is suitable for liquid or fine powder materials with good fluidity. Other shapes can also be set according to specific process requirements and material characteristics. Container 2 can be stainless steel, which is resistant to high temperature and corrosion, has high mechanical strength, is suitable for most industrial environments, and is used for various materials in the production of photovoltaic glass with low melting points. Container 2 can also be ceramic, which is resistant to high temperature and chemical corrosion, suitable for materials under extreme conditions, and suitable for high temperature molten materials, such as molten silicon. Container 2 can also be graphite, which is resistant to high temperature and has good conductivity, and is suitable for materials that need to be conductive. The container 2 can also be made of heat-resistant glass, which has high transparency and high temperature resistance, and is suitable for occasions where the state of materials needs to be observed, and is suitable for small batch feeding tests in laboratories. More specifically, the container 2 can be a crucible, such as a platinum crucible.

[0045] Specifically, a heating element can be embedded in the bottom or side wall of the container 2 to preheat the material and prevent condensation and sudden temperature changes. A temperature sensor and a controller can also be integrated to monitor and adjust the temperature in the container 2 in real time. An agitator can also be installed inside the container 2 to help the material mix evenly and reduce agglomeration and bubbles. The top of the container 2 is equipped with a sealing cover to prevent material leakage and contamination. A high-temperature resistant sealing ring can also be used to ensure the sealing effect. A weight sensor is also installed at the bottom of the container 2 to monitor the weight of the material in real time. A liquid level sensor can also be installed inside the container 2 to monitor the liquid level of the material.

[0046] The container 2 can be firmly connected to the support platform 1 by bolts, clamps or other fixing devices to ensure that it will not loosen or fall off during the lifting and rotation process. It is suitable for production environments where the feeding frequency is low and the material container 2 is fixed, with a stable connection and simple operation. A quick release device (such as a quick-change clamp, latch, etc.) can also be used to quickly replace the container 2 in a short time. It is suitable for production environments where material containers 2 of different specifications or types need to be frequently replaced, with quick operation and high flexibility.

[0047] The container 2 can also be connected to the support platform 1 through a slide rail. A slide rail is provided at the bottom of the container 2, and a corresponding guide rail is provided on the support platform 1. The container 2 is pushed in or pulled out by sliding to facilitate loading and unloading, which is suitable for production environments that require frequent loading and unloading. The slide rail needs to be lubricated and cleaned regularly to prevent jamming. The container 2 can also be magnetically connected to the support platform 1, and a magnet or electromagnet is used to adsorb the container 2 on the support platform 1, which is suitable for containers 2 made of iron or magnetic materials. It is suitable for production environments that require temporary fixation of the container 2. It is easy to connect and disassemble, and there is no wear. The container 2 can also be connected to the support platform 1 by a hook. Specifically, a hook or a lifting ring is provided on the container 2, and a corresponding hanging point or hook is provided on the support platform 1. The container 2 is fixed by a hook, which is suitable for large containers 2 that need to be suspended and fixed.

[0048] The lifting mechanism 3 is a mechanical device for realizing the movement of an object in the vertical direction. In the production of photovoltaic glass, the lifting mechanism 3 is mainly used to move the support platform 1 and the material container 2 thereon from the outside of the melting furnace to the inside of the melting furnace, or vice versa. Specifically, the lifting mechanism 3 can be an electric cylinder lifting mechanism 3, which uses an electric motor to drive a lead screw or a gear rack mechanism to achieve linear motion. High-precision position control can be achieved through an encoder and a controller. The electric cylinder has a fast response speed and is suitable for occasions that require rapid lifting. It runs smoothly and has low noise, which is suitable for photovoltaic glass production with high requirements for precision and speed. The lifting mechanism 3 can also be a hydraulic cylinder lifting mechanism 3, which uses the pressure of hydraulic oil to drive the piston rod to achieve linear motion. The hydraulic cylinder has a large load-bearing capacity and is suitable for heavy-load occasions. The hydraulic system can provide stable thrust and is suitable for long-term continuous work. It is suitable for production environments that require large load capacity and high stability. The lifting mechanism 3 can also be a pneumatic cylinder lifting mechanism 3, which uses the pressure of compressed air to drive the piston rod to achieve linear motion. The initial investment and maintenance cost of the pneumatic system are low, the pneumatic cylinder has a fast response speed, and is suitable for occasions that require rapid action. The pneumatic system is not easy to overheat and has high safety, which is suitable for occasions with high requirements for cost and safety. The lifting mechanism 3 can also be a chain 31 transmission lifting mechanism 3, using an electric motor or a handwheel to drive the sprocket 32, and transmitting power through the chain 31 to drive the lifting platform up and down. The chain 31 transmission has a large carrying capacity and is suitable for heavy-duty occasions. The chain 31 transmission structure is simple and easy to maintain. The accuracy of the chain 31 transmission is relatively low, which is suitable for occasions where high accuracy requirements are not high. It is suitable for production environments that require large load capacity and simple structure. The lifting mechanism 3 can also be a spiral lifting mechanism 3, using a motor to drive the screw, and realizing linear motion through the rotation of the nut. The spiral transmission has high accuracy and is suitable for occasions that require high-precision control. The spiral transmission has self-locking properties and can maintain the current position after power failure. It is suitable for occasions that require high accuracy and self-locking properties.

[0049] Through the above technical solution, the photovoltaic glass melting furnace feeding device provided by the present disclosure drives the support platform 1 to move downward through the lifting mechanism 3 to open the furnace bottom, so that the container 2 leaves the furnace body along with the support platform 1, which is convenient for the staff to add materials to the crucible. After the addition is completed, the support platform 1 is driven upward by the lifting mechanism 3 to reset, thereby sealing the furnace bottom and continuing heating. By opening the furnace bottom and bringing the container 2 outside the furnace body for heating, the working space for adding materials in the furnace body is saved, so that the required space in the furnace body can be smaller, further increasing the temperature increase rate in the furnace, reducing the power of electric heating, and thus reducing the experimental cost.

[0050] In some embodiments, the lifting mechanism 3 includes a plurality of chains 31 and a plurality of sprockets 32, the first end of the chain 31 is connected to the support platform 1, and the plurality of chains 31 are respectively connected to the plurality of sprockets 32. The first end of the chain 31 can be fixed to the bottom or side of the support platform 1 by a fixing device (such as a bolt or a clamp). The second end of the chain 31 can be directly connected to the sprocket 32, and the lifting movement is realized by the rotation of the sprocket 32. The second end of the chain 31 can also bypass the sprocket 32 ​​to connect with other mechanisms. The plurality of sprockets 32 are distributed at different positions of the lifting mechanism 3 to ensure uniform force and stable movement of the chain 31. The sprocket 32 ​​can be driven by a motor, rotated by gear transmission or direct drive, and drive the chain 31 to move, or the sprocket 32 ​​can be rotated manually. The motor can also be connected to an encoder and a controller, and accurate position control and speed regulation can be realized by the encoder and the controller. An upper limit structure and a lower limit structure can also be set on the support platform 1 or the sprocket 32 ​​to prevent the support platform 1 from exceeding a predetermined range and ensure safe operation.

[0051] When in use, the operator starts the motor through the control panel, and the motor starts to rotate. The motor rotates the drive sprocket 32 ​​by gear transmission or direct drive. The rotation of the drive sprocket 32 ​​drives the chain 31 to move, and the first end of the chain 31 is connected to the support platform 1. As the chain 31 moves, the support platform 1 is lifted or lowered. The support platform 1 moves up and down along the guide rail to ensure the smoothness and linearity of the movement. When the support platform 1 reaches a predetermined position, the limit device is triggered, the motor stops rotating, and the support platform 1 stops moving. The combination of multiple chains 31 and multiple sprockets 32 can disperse the load and improve the carrying capacity, which is suitable for heavy load occasions. The chain 31 and the sprocket 32 ​​have a simple structure and run smoothly, which can ensure the stability of the support platform 1 during the lifting process. The chain 31 and the sprocket 32 ​​have a simple structure and are easy to maintain. Regular inspection and lubrication can ensure long-term stable operation. Compared with hydraulic cylinders and electric cylinders, the lifting mechanism 3 of the chain 31 and the sprocket 32 ​​has a lower cost and is suitable for small and medium-sized enterprises and laboratories.

[0052] In some embodiments, the lifting mechanism 3 also includes a gear shaft 33, and the multiple chains 31 are connected to the gear shaft 33 after passing through the sprocket 32, and the gear shaft 33 is connected to the driving unit 34. The gear shaft 33 is a shaft with a gear, which is usually used to transmit rotational motion and torque. In this device, the gear shaft 33 is used to connect the driving source (such as a motor) and the actuator (such as the sprocket 32) to ensure efficient transmission and synchronous motion of power. In the lifting mechanism 3 of photovoltaic glass production, the gear shaft 33 plays a key role to ensure the synchronous motion of the multiple chains 31 and the stability of the system. The driving unit 34 is the core component of the lifting mechanism 3, which is responsible for providing power and controlling the lifting motion. In the production of photovoltaic glass, the driving unit 34 can be a hand wheel, or it can include a motor, a reducer, a controller and related accessories, which work together to ensure the efficient, stable and precise operation of the lifting mechanism 3. After the multiple chains 31 pass through the sprocket 32, they are connected to the gear shaft 33 to ensure the synchronous motion of the chains 31. The gear shaft 33 transmits the power of the driving unit 34 to the sprocket 32 ​​to achieve synchronous rotation of the chain 31. The motor provides power to drive the gear shaft 33 to rotate. The reducer cooperates with the motor to reduce the speed and increase the torque to ensure sufficient driving force. Accurate position control and speed regulation are achieved through the encoder and controller.

[0053] Since the temperature in the sample dissolving furnace is as high as 1600°C, each time the furnace door is opened to add materials into the container, the crucible will radiate a large amount of heat energy due to the high temperature and the crucible is close to the chain 31, resulting in a large amount of heat radiation to the chain 31. Therefore, the chain 31 in this patent is made of heat-resistant steel to ensure the strength and service life of the chain 31.

[0054] In some embodiments, the lifting mechanism 3 further includes a counterweight platform 36, which is connected to the second end of the chain 31, and a plurality of counterweight blocks 35 are arranged on the counterweight platform 36. The counterweight platform 36 is a device attached to the lifting mechanism 3, and the weight of the support platform 1 and the material container 2 thereon is balanced by arranging a plurality of counterweight blocks 35 on the platform. The main function of the counterweight platform 36 is to close the furnace door, reduce the load of the drive unit 34, and improve the stability and efficiency of the system. The counterweight platform 36 is similar to the support platform 1, and is a solid platform for placing the counterweight blocks 35. The weight of the plurality of counterweight blocks 35 can be adjusted as needed to ensure the weight balance with the support platform 1 and the material container 2 thereon. As the material is added multiple times, the weight of the material in the container 2 gradually increases, and the weight of the counterweight needs to be increased to ensure that the furnace door does not fall. When the furnace door is opened for adding material, the counterweight can be appropriately reduced, and the weight of the crucible can be used to make the furnace door easier and faster to open.

[0055] In some embodiments, the first ends of the multiple chains 31 are evenly distributed around the support platform 1; a heating element is also provided on the support platform 1, and the heating element is used to heat the material in the container 2. Number of chains 31: According to the size and load requirements of the support platform 1, multiple chains 31 (for example, 4, 6 or more) can be selected. Specifically, the radical chains 31 can be evenly distributed at the four corners of the support platform 1. The first ends of the multiple chains 31 are evenly distributed around the support platform 1 to ensure that the support platform 1 is evenly stressed during the lifting process. The evenly distributed chains 31 can ensure that the support platform 1 remains balanced during the lifting process to avoid tilting and shaking. Multiple chains 31 share the load, improve the stability of the system, avoid excessive stress on a single chain 31, and extend the service life of the chain 31.

[0056] The heating element can be a resistance heating wire, a heating plate or a heating tube, etc., and a suitable heating element is selected according to specific needs. The heating element is installed at the bottom or side wall of the support platform 1, close to the container 2, to ensure that heat can be effectively transferred to the material. The temperature control system is equipped with a temperature sensor and a controller to achieve precise control of the heating element and ensure the stability of the material temperature. The material can be preheated by the heating element to ensure that the material maintains the required temperature during the feeding process and prevent sudden temperature changes. Hot materials can speed up the melting process and improve production efficiency. Through precise temperature control, unnecessary energy waste is reduced.

[0057] In some embodiments, the device further includes a heat preservation platform 4, which is arranged on the top of the support platform 1, and the container 2 is arranged on the top of the heat preservation platform 4; the heat preservation platform 4 can block the bottom opening of the melting furnace. Specifically, the heat preservation platform 4 is arranged on the top of the support platform 1, and is used to place the container 2. The heat preservation platform 4 can be made of materials with high temperature resistance and good heat insulation performance, such as ceramic fiberboard, refractory bricks or heat insulation cotton. The shape of the heat preservation platform 4 matches the bottom opening of the melting furnace to ensure that the bottom opening of the melting furnace can be completely blocked. The edge of the heat preservation platform 4 can be designed with a sealing strip or a sealing gasket to ensure a close fit with the bottom opening of the melting furnace to prevent heat loss. The heat preservation platform 4 can reduce heat loss and keep the temperature of the material in the container 2 stable. The heat preservation platform 4 can block the bottom opening of the melting furnace to prevent heat loss and external impurities from entering the melting furnace.

[0058] In some embodiments, the lifting mechanism 3 further includes a limiter, which can be connected to the gear shaft 33 to limit the lifting mechanism 3 at a set position. The limiter is an important component of the lifting mechanism 3, and is used to limit the range of movement of the support platform 1 to ensure that it stops at a predetermined position. The limiter can prevent the support platform 1 from excessively rising or falling, thereby avoiding equipment damage and operating accidents. The limiter can be a limit switch fixed on the support platform 1, or a mechanical limiter connected to the gear shaft 33. Mechanical limit means limiting the range of movement of the support platform 1 by physical blocking to ensure that it stops at a predetermined position. For example, the mechanical limit can be a fixed stopper, which is installed at the upper and lower parts of the guide rail and can be a metal block fixed on the guide rail. The contact surface of the stopper contacts the corresponding part of the support platform 1 or the counterweight platform 36 to prevent it from continuing to move. When the support platform 1 or the counterweight platform 36 contacts the stopper, the physical block stops it from moving. The position of the stopper can be adjusted as needed to ensure that the support platform 1 stops at a predetermined position. Mechanical limit can also be a threaded limit adjustment, which is installed on one side of the guide rail and can be adjusted by rotating the limit position. The limit block is fixed on the screw rod, and the position of the limit block is adjusted by rotating the screw rod. By rotating the screw rod, the position of the limit block is adjusted so that it contacts the support platform 1 or the counterweight platform 36 at a predetermined position to prevent it from moving further. The position of the screw rod can be fine-tuned as needed to ensure the accuracy of the limit position. The spring can also be installed on one side of the guide rail, and the limit position can be adjusted by the expansion and contraction of the spring. The limit block is fixed at one end of the spring, and the position of the limit block is adjusted by the expansion and contraction of the spring. When the support platform 1 contacts the limit block, the expansion and contraction of the spring can absorb the impact force and reduce the damage caused by the collision. The elastic force of the spring can be adjusted as needed to ensure the accuracy and stability of the limit position. The electrical limit is to detect the position of the support platform 1 through a limit switch or a photoelectric sensor, and the signal is fed back to the controller to control the motor to stop. The limit part is connected to the gear shaft 33 by a bolt, a pin or other fixing device to ensure that it can play a reliable role when needed.

[0059] In some embodiments, a blocking structure is provided on the side wall of the heat preservation platform 4, and the blocking structure can block the gap between the heat preservation platform 4 and the bottom opening side wall of the melting furnace. The blocking structure is a device installed on the side wall of the heat preservation platform 4, which is used to block the gap between the heat preservation platform 4 and the bottom opening side wall of the melting furnace. The main function of the blocking structure is to reduce heat loss, prevent external impurities from entering the melting furnace, and ensure the temperature stability and purity in the melting furnace. Specifically, the blocking structure can be a sealing strip, and the sealing strip can be made of high temperature resistant and corrosion resistant materials, such as silicone rubber, graphite or ceramic fiber wool. The sealing strip can be strip-shaped or ring-shaped, installed on the side wall of the heat preservation platform 4, and tightly fit with the bottom opening side wall of the melting furnace. When the heat preservation platform 4 rises to a predetermined position, the sealing strip is tightly fitted with the bottom opening side wall of the melting furnace to block the gap between the two. The flexibility and high temperature resistance of the sealing strip ensure a good sealing effect. The sealing structure can also be a mechanical seal, including a sealing ring and an adjusting device. The sealing ring is installed on the side wall of the heat preservation platform 4, and the position of the sealing ring is adjusted by the mechanical device. The adjusting device can be a screw, a spring or other mechanical device, which is used to adjust the position and pressure of the sealing ring. When the heat preservation platform 4 rises to a predetermined position, the sealing ring is tightly fitted with the side wall of the bottom opening of the melting furnace through the adjusting device to seal the gap between the two. The adjusting device can be fine-tuned as needed to ensure the sealing effect.

[0060] Example 2

[0061] A photovoltaic glass melting furnace comprises the photovoltaic glass melting furnace feeding device of Example 1. The glass melting furnace comprises a furnace body, a heating element, a temperature control system and a bottom opening. The furnace body is the main part, which is used to accommodate a high temperature environment and is usually made of high temperature resistant materials, such as refractory bricks or high temperature alloys. The heating element is installed in the furnace body to provide a high temperature environment, and can be a resistance heating wire, a heating plate or a heating tube. The temperature control system includes a temperature sensor and a controller for monitoring and controlling the temperature in the furnace. The bottom opening is used for feeding and sampling, and is a sealable opening. The support platform 1 of the feeding device is arranged at the bottom opening, and the chain 31 is arranged on the outside of the furnace body.

[0062] Through the above technical solution, the photovoltaic glass melting furnace provided by the present disclosure drives the support platform 1 to move downward through the lifting mechanism 3 to open the furnace bottom, so that the container 2 leaves the furnace body along with the support platform 1, which is convenient for the staff to add materials to the crucible. After the addition is completed, the support platform 1 is driven upward by the lifting mechanism 3 to reset, thereby sealing the furnace bottom and continuing heating. By opening the furnace bottom and bringing the container 2 outside the furnace body for heating, the working space for adding materials in the furnace body is saved, so that the required space in the furnace body can be smaller, further increasing the temperature increase rate in the furnace, reducing the power of electric heating, and thus reducing the experimental cost.

[0063] Example 3

[0064] A method for using the above-mentioned photovoltaic glass melting furnace comprises the following steps: lowering the support platform 1 provided at the bottom of the melting furnace so that the container 2 in the melting furnace is moved outside the melting furnace; adding materials to the container 2; raising the support platform 1 below the melting furnace so that the support platform 1 contacts the bottom surface of the melting furnace to seal the bottom of the melting furnace, and the container 2 enters the melting furnace. As the material is added multiple times, the weight of the material in the container 2 gradually increases. In order to ensure that the furnace door does not fall, the weight of the counterweight needs to be increased. When opening the furnace door for adding materials, the counterweight can be appropriately reduced, and the furnace door can be opened more easily and quickly by using the deadweight of the crucible. Specifically, the steps of the method of use are as follows:

[0065] 1) Preparation stage:

[0066] Check the equipment: ensure that all components (such as the motor, reducer, chain 31, sprocket 32, gear shaft 33, counterweight platform 36, stopper, heating element, etc.) are in good condition and are not damaged or loose.

[0067] Check the temperature: Make sure the furnace has been preheated to the required operating temperature.

[0068] Check container 2: Make sure container 2 is clean and free of impurities, and place it on the insulation platform 4.

[0069] 2) Descending support platform 1:

[0070] Start the motor: Start the motor through the control panel and the motor starts to rotate.

[0071] The gear shaft 33 rotates: the motor drives the gear shaft 33 to rotate via the speed reducer.

[0072] The sprocket 32 ​​rotates: the rotation of the gear shaft 33 is transmitted to the chain 31 through the sprocket 32, and the multiple sprockets 32 rotate synchronously.

[0073] Movement of the chain 31: The rotation of the sprocket 32 ​​drives the chain 31 to move, and the first ends of the multiple chains 31 are evenly distributed around the supporting platform 1 to ensure that the supporting platform 1 maintains balance during the descent process.

[0074] The support platform 1 descends: the support platform 1 descends along the guide rail until the container 2 is completely moved out of the melting furnace.

[0075] Limiting part triggering: when the supporting platform 1 descends to a predetermined position, the limiting part is triggered, the motor stops rotating, and the supporting platform 1 stops descending.

[0076] 3) Add materials to container 2:

[0077] Open container 2: remove container 2 from the heat preservation platform 4 and open the cover of container 2.

[0078] Adding materials: Add the raw materials to be melted (such as quartz sand, soda ash, etc.) into container 2.

[0079] Close Container 2: Replace the lid on Container 2 to ensure a tight seal.

[0080] Placing container 2: Re-place container 2 containing raw materials on heat preservation platform 4, and ensure that container 2 is firmly positioned on heat preservation platform 4.

[0081] 4) Rising support platform 1:

[0082] Start the motor: Start the motor via the control panel and the motor starts to rotate in the reverse direction.

[0083] The gear shaft 33 rotates: the motor drives the gear shaft 33 to rotate in the opposite direction through the speed reducer.

[0084] The sprocket 32 ​​rotates: the rotation of the gear shaft 33 is transmitted to the chain 31 through the sprocket 32, and the multiple sprockets 32 rotate synchronously.

[0085] Movement of the chain 31: The rotation of the sprocket 32 ​​drives the chain 31 to move, and the first ends of the multiple chains 31 are evenly distributed around the supporting platform 1 to ensure that the supporting platform 1 maintains balance during the ascending process.

[0086] The support platform 1 rises: the support platform 1 rises along the guide rail until the heat preservation platform 4 contacts the bottom opening side wall of the melting furnace, and the container 2 completely enters the melting furnace.

[0087] Limiting part triggering: when the supporting platform 1 rises to a predetermined position, the limiting part is triggered, the motor stops rotating, and the supporting platform 1 stops rising.

[0088] Sealing structure operation: The sealing structure (such as sealing strip, pneumatic seal or mechanical seal) on the side wall of the insulation platform 4 fits tightly with the bottom opening side wall of the melting furnace to seal the gap between the two, ensuring the temperature stability and purity in the melting furnace.

[0089] 5) Heating and melting:

[0090] Start the heating elements: Start the heating elements in the melting furnace through the control panel to ensure that the temperature in the furnace reaches the required melting temperature.

[0091] Monitor temperature: Use temperature sensors and controllers to monitor the temperature in the melting furnace in real time to ensure that the temperature is stable within the set range.

[0092] Melting raw materials: At the set temperature, the raw materials gradually melt to form the required glass liquid.

[0093] 6) Sampling or unloading:

[0094] Lowering the support platform 1: When the melting is completed, the motor is started through the control panel to lower the support platform 1 and move the container 2 out of the melting furnace.

[0095] Sampling or unloading: remove the container 2 from the insulation platform 4 and perform sampling or unloading operations.

[0096] Cleaning container 2: Clean container 2 and prepare for next use.

[0097] Through the above technical solution, the photovoltaic glass melting furnace provided by the present disclosure drives the support platform 1 to move downward through the lifting mechanism 3 to open the furnace bottom, so that the container 2 leaves the furnace body along with the support platform 1, which is convenient for the staff to add materials to the crucible. After the addition is completed, the support platform 1 is driven upward by the lifting mechanism 3 to reset, thereby sealing the furnace bottom and continuing heating. By opening the furnace bottom and bringing the container 2 outside the furnace body for heating, the working space for adding materials in the furnace body is saved, so that the required space in the furnace body can be smaller, further increasing the temperature increase rate in the furnace, reducing the power of electric heating, and thus reducing the experimental cost.
