Description

Technical Field

[0001] This utility model relates to the field of furnace cooling technology, specifically a condensation and heat dissipation device for a perovskite annealing furnace. Background Technology

[0002] Traditional perovskite annealing furnaces present several problems, one of the most significant being heat dissipation. Currently, the internal temperature of traditional perovskite annealing furnaces reaches as high as 600 degrees Celsius, requiring a furnace body thickness of 80-100mm. This results in uneven temperature distribution between the furnace interior and exterior. During production, the external furnace temperature remains high and ineffective heat dissipation leads to prolonged periods of high temperatures in the workshop, impacting worker comfort and safety. Furthermore, temperature can easily transfer between different furnace sections. Traditional cooling methods typically employ natural cooling or air cooling, but these methods are ineffective, inefficient, and hinder the stable control of the furnace temperature within the set range, ultimately reducing product quality and yield. Summary of the Invention

[0003] The purpose of this invention is to provide a condensation and heat dissipation device for a perovskite annealing furnace body. The device delivers condensing gas into the furnace body through a condenser, and the condensing gas dissipates heat to automatically regulate the temperature of the furnace body shell, thereby improving cooling efficiency, product quality, and yield. This solves the problems of unsatisfactory cooling effect and low cooling efficiency of traditional cooling methods mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A condensation and heat dissipation device for a perovskite annealing furnace includes a furnace body with a furnace cavity. A condensation assembly communicating with the furnace cavity is disposed outside the furnace body. The condensation assembly includes a condenser, a first gas pipe, a second gas pipe, and a solenoid valve. The condenser is installed on the top surface of the furnace body.

[0006] Preferably, the exhaust gas recovery structure includes a centrifugal fan, a transition pipe, and an exhaust pipe.

The other end of the transition pipe is connected to one end of the exhaust pipe.

[0007] Preferably, the centrifugal fan includes a volute, an upper connecting plate, a lower connecting plate, blades, and a motor. The volute is installed on the top surface of the furnace body. The upper and lower connecting plates are arranged opposite each other inside the volute. The blades are a plurality of blades distributed in a circumferential shape between the upper and lower connecting plates. The motor is installed on the top of the volute, and the output shaft of the motor passes through the top wall of the volute and extends downward into the volute to connect with the upper connecting plate.

[0008] Preferably, the bottom surface of the volute has an air inlet communicating with the exhaust gas outlet, and the side surface of the volute has an air outlet communicating with the transition pipe.

[0025] 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.

[0026] Please see Figure 1 A condensation and heat dissipation device for a perovskite annealing furnace body includes a furnace body 1 with a furnace cavity, and a condensation assembly 2 communicating with the furnace cavity is disposed outside the furnace body 1. Please refer to [link to relevant documentation]. Figure 2 The condensing assembly 2 includes a condenser 21, a first gas pipe 22, a second gas pipe 23, and a solenoid valve 24. The condenser 21 is installed on the top surface of the furnace body 1 and is used to supply condensed gas into the furnace body 1 for cooling the furnace wall. One end of the first gas pipe 22 is connected to the condenser 21, and the other end is connected to the side wall of the furnace body 1. One end of the second gas pipe 23 is connected to the condenser 21. The solenoid valve 24 is installed at the connection between the second gas pipe 23 and the condenser 21 to control the conduction state of the second gas pipe 23. Please refer to [link / reference]. Figure 5 The furnace body 1 has a tail gas discharge port 11 in the middle of the top surface, and a tail gas recovery structure 3 is provided at the outlet. In this embodiment, the second gas pipe 23 is connected to a pressure regulating valve 25 at one end relative to the condenser 21 to achieve more precise pressure regulation; a temperature detection device 4 extending into the furnace body 1 is provided on the top surface of the furnace body 1, and the temperature detection device 4 is a temperature sensor.

[0027] This invention uses a temperature detection device 4 to detect the temperature of the furnace body 1's outer shell. When the temperature is higher than the set temperature, condenser 21 delivers condensate gas into the furnace body 1. The condensate gas dissipates heat to automatically regulate the temperature of the furnace body 1's outer shell and achieves temperature isolation, thereby improving cooling efficiency, product quality, and pass rate. At the same time, it reduces the thermal shock and erosion of the furnace body 1 material caused by high temperature, thus extending the service life of the furnace body 1 and reducing equipment maintenance and replacement costs.

[0028] The flow rate and temperature of the condensate gas are adjustable, ensuring that the internal temperature of the furnace body 1 is stably controlled within a set range during both the heating and cooling stages of the annealing process. This guarantees product quality stability and reduces inconsistencies in product performance caused by temperature fluctuations. Furthermore, the condensate gas can be recovered and reused for heat through the exhaust gas recovery structure 3. Compared to some existing annealing furnaces with poor heat dissipation, this embodiment reduces heat loss within the workshop through condensate gas cooling, lowers the ambient temperature, improves working conditions for workers, and enhances work comfort and safety.

[0029] Please see Figure 3-4 The exhaust gas recovery structure 3 includes a centrifugal fan 31, a transition pipe 32, and an exhaust pipe 33. One end of the centrifugal fan 31 is connected to the exhaust gas outlet 11, and the other end is connected to one end of the transition pipe 32. The other end of the transition pipe 32 is connected to one end of the exhaust pipe 33, and the other end of the exhaust pipe 33 is connected to an external pipe. In this embodiment, the heat carried by the condensate in the exhaust pipe 33 can be used to preheat the workpiece to be processed or other processes requiring heating, improving energy utilization, reducing overall energy consumption, meeting the requirements of energy conservation and emission reduction, and helping to reduce production costs.

[0030] Please see Figure 6-7 The centrifugal fan 31 includes a volute 311, an upper connecting plate 312, a lower connecting plate 313, blades 314, and a motor 315. The volute 311 is installed on the top surface of the furnace body 1. The bottom surface of the volute 311 has an air inlet communicating with the exhaust port 11, and the side surface of the volute 311 has an air outlet communicating with the transition pipe 32. The upper connecting plate 312 and the lower connecting plate 313 are arranged vertically opposite each other inside the volute 311. Several blades 314 are arranged in a circumferential shape between the upper connecting plate 312 and the lower connecting plate 313. The motor 315 is installed on the top of the volute 311, and the output shaft of the motor 315 passes through the top wall of the volute 311 and extends downward into the volute 311 to connect with the upper connecting plate 312. When recovering exhaust gas, the motor 315 drives the upper connecting plate 312, the lower connecting plate 313 and the blades 314 to rotate together, drawing the gas in the furnace body 1 into the volute 311, and then flowing through the gas outlet of the volute 311 to the transition pipe 32 and being discharged from the exhaust pipe 33.

[0031] In this embodiment, the upper and lower ends of the blade 314 are respectively threaded to the upper connecting plate 312 and the lower connecting plate 313 by bolts, and the blade 314 is an arc-shaped plate structure.

[0032] Please see Figure 4-5 The exhaust gas recovery structure 3 includes a first flange 34, a second flange 35, and a pneumatic butterfly valve 36. One end of the first flange 34 is connected to the exhaust gas outlet 11, and the other end is connected to the pneumatic butterfly valve 36. The pneumatic butterfly valve 36 is connected to the second flange 35 at the end opposite to the first flange 34, and the second flange 35 is connected to the centrifuge at the end opposite to the pneumatic butterfly valve 36. In this embodiment, the end of the second flange 35 opposite to the pneumatic butterfly valve 36 is connected to the air inlet of the volute 311.

[0033] The pneumatic butterfly valve 36 includes a valve body, a valve stem, a valve plate, and a pneumatic actuator. The valve body has a flow channel connected to a first flange 34 and a second flange 35. The valve stem is laterally rotatable within the flow channel. The valve plate is connected to the valve stem, and its periphery abuts against the inner wall of the flow channel. One end of the valve stem passes through the valve body and connects to the pneumatic actuator. In this embodiment, the pneumatic actuator drives the valve plate on the valve stem to rotate, thereby opening and closing the flow channel of the valve body and controlling the gas flow rate.

[0034] Please see Figure 2 as well as Figure 8 The exhaust port 11 of the furnace body 1 is equipped with a filter assembly 5. The filter assembly 5 includes a frame 51 fixed to the furnace wall of the furnace body 1 and a filter plate 52 embedded in the middle of the frame 51. The surface of the filter plate 52 has evenly distributed filter holes for filtering impurities in the gas. In this embodiment, the outer edge of the frame 51 has circumferentially distributed grooves for embedding in the peripheral wall of the exhaust port 11.

[0035] The working principle of the condensation and heat dissipation device for the perovskite annealing furnace body of this utility model is as follows: When the temperature detection device 4 detects that the temperature of the furnace body 1 is higher than the set temperature, the condenser 21 starts to deliver condensing gas into the furnace body 1 to automatically adjust the temperature of the outer shell of the furnace body 1. When the temperature detection device 4 detects that the temperature of the furnace body 1 is lower than the set temperature, the condenser 21 stops delivering condensing gas to achieve precise temperature control, so that the workpiece is heated evenly during the annealing process, thereby improving the quality and pass rate of the product. During the heat dissipation process, the condensing gas is discharged through the tail gas discharge port 11 on the top surface of the furnace body 1. At this time, the motor 315 of the centrifugal fan 31 starts, drawing the gas in the furnace body 1 into the volute 311, and then flowing through the outlet of the volute 311 to the transition pipe 32 and being discharged to the outside through the exhaust pipe 33, or used for preheating the workpiece to be processed or other processes that require heating.

[0036] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
