Description

Technical Field

[0001] The utility model relates to the technical field of ion exchange furnace structures, and more specifically to a lifting type ion exchange furnace structure. Background Art

[0002] Ion exchange is one of the most critical production processes in the production of self-focusing lenses. When it is completed, the exchange wire and the molten salt must be separated in a timely manner. The existing technology adopts a structure that opens the furnace cover and slowly lifts the wire reel from the molten salt.

[0003] However, during the heating process of the lift-type ion exchange furnace, the temperature inside the furnace is too high, making it difficult for personnel to accurately judge the internal temperature. As a result, when in use, if the temperature inside the furnace is too high, the electric heating element will burn out. At the same time, if the thermocouple is suddenly pulled out at high temperature, it will also cause the outer shell to explode, thus posing a safety hazard. Therefore, this solution proposes a lift-type ion exchange furnace structure. Utility Model Content

By utilizing the temperature memory of the deformation memory alloy, the temperature inside the furnace is monitored, so that personnel can control the furnace temperature in real time to ensure the normal furnace temperature inside the furnace. At the same time, when the temperature is high, the temperature monitoring component will warn the outside world, indicating that it is not appropriate to pull out the thermocouple under high temperature conditions to avoid the occurrence of cracking of the outer shell.

[0013] 3. Beneficial effects:

[0014] Compared with the prior art, the technical solution provided by this utility model has the following beneficial effects:

[0015] The utility model has a reasonable design. By utilizing the temperature memory of the deformation memory alloy, the temperature inside the furnace is monitored for hot and cold temperatures, so that personnel can control the furnace temperature in real time to ensure the normal furnace temperature inside the furnace. At the same time, when the temperature is high, the temperature monitoring component warns the outside world, prompting that it is not appropriate to pull out the thermocouple under the high temperature state to avoid the occurrence of the phenomenon of the outer shell bursting.

[0016] According to the utility model, when the temperature inside the furnace body is too low, the shape memory alloy column does not deform and gradually returns to its initial shape. At this time, the shape memory alloy column retracts to the rear side of the infrared detector, so that the infrared detector cannot detect objects between the inner walls. The infrared detector sends a signal to the warning light, indicating that the temperature inside the furnace body is low and timely adjustment is required.

[0017] According to the present invention, when the temperature inside the furnace body is too high, the shape memory alloy column extends and deforms to the limit value under the influence of temperature, thereby contacting the surface of the pressure-sensitive component. As a result, the pressure-sensitive component sends a signal to the warning light, thereby notifying the outside world that the inside of the furnace body is in a high-temperature state and timely adjustments are required.

[0018] The deformation threshold of the shape memory alloy column of the utility model can be replaced accordingly according to the specific operating environment and materials of the personnel, so that it is applicable to various scenarios and has a wider range. During the replacement work, the personnel only need to take out the installation sleeve from the inside of the installation hole and replace it.

[0019] It should be noted that the structures not introduced in the present invention do not involve the design points and improvement directions of the present invention, and are the same as the existing technology or can be implemented by using the existing technology, so they are not described in detail here.

[0031] To facilitate understanding of the present invention, the present invention will be described more comprehensively below with reference to the relevant drawings. Several embodiments of the present invention are given in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

Thus, a feature specified as "first" or "second" may explicitly or implicitly include one or more of such features. In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0034] In this utility model, unless otherwise expressly specified or limited, the terms "installed," "connected," "connected," "fixed," "provided with," "provided on," etc. should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integral connection; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; or internal communication between two components. Those skilled in the art will be able to understand the specific meanings of the above terms in this utility model based on specific circumstances. Example

[0035] See also Figure 1-5 A lifting ion exchange furnace structure includes a frame 1, a furnace body 2 is installed between the upper inner walls of the frame 1, a plurality of transmission rods 3 are installed between the lower end of the furnace body 2 and the bottom side wall of the frame 1, a limiting sleeve 4 is installed between the multiple transmission rods 3 on one side, a fixed bracket 5 is fixedly connected between the inner walls of the limiting sleeve 4, a crucible 6 is installed on the upper end of the fixed bracket 5, a controller 7 is provided at the side end of the frame 1, and a temperature monitoring component 8 is installed on one side of the furnace body 2.

[0036] During use, this solution avoids the existing lifting ion exchange furnace from overheating or overcooling during the heating process, resulting in the temperature in the furnace exceeding the set furnace operating temperature, thereby burning the electric heating element, and the phenomenon that the thermocouple is suddenly pulled out at high temperature and the outer shell explodes. In this embodiment, the temperature in the furnace is monitored by using the temperature memory of the deformation memory alloy, so that the personnel can control the furnace temperature in real time to ensure the normal furnace temperature inside the furnace. At the same time, when the temperature is high, the temperature monitoring component 8 warns the outside world, prompting that it is not appropriate to pull out the thermocouple under high temperature to avoid the explosion of the outer shell.

[0037] The lift-type ion exchange furnace consists of a furnace body 2, a crucible 6, a molten salt layer, a wire reel, and a heating source. Crucible 6 contains a molten salt layer, the top of the wire reel is fixed to the furnace body 2, and crucible 6 is fixed to a fixed bracket 5, with a heating source located below. This allows the exchange process to proceed without interrupting heating, ensuring efficient exchange and equipment stability.

[0038] During use, personnel can electrically control the controller 7 to cause the fixed bracket 5 to drive the crucible 6 to move up and down, thereby exchanging work inside the furnace body 2. At the same time, when the furnace body 2 rises, its high-temperature gas is received by the temperature monitoring component 8 on one side, so that the temperature inside the furnace body 2 can be detected. In this way, personnel can judge whether the temperature inside the furnace body 2 is too high or too low from the outside, and the temperature inside the furnace can be monitored in real time to ensure the normal operating temperature inside the chamber.

[0039] See also Figure 1-4 The temperature monitoring component 8 includes a monitoring box 81 fixedly connected to the side end of the frame 1, a detection component 82 is embedded in the front end of the monitoring box 81, a cavity is opened inside the monitoring box 81, an infrared detector 83 is installed at the top of the cavity, a pressure-sensitive component 84 is installed on the rear side wall of the cavity, and a power supply box 85 is fixedly connected to the bottom end of the monitoring box 81, and a warning light 86 is installed at the outer end of the power supply box 85.

[0040] More specifically: a placement hole 811 is provided at the front end of the monitoring box 81, a ventilation hole 21 is provided at the side end of the furnace body 2, and a second ventilation hole 812 is also provided at the front end of the monitoring box 81. The detection component 82 is located between the inner walls of the placement hole 811, and the second ventilation hole 812, the placement hole 811, the ventilation hole 21, and the installation sleeve 821 are interconnected.

[0041] More specifically, the detection member 82 includes a mounting sleeve 821 fixedly connected between the inner walls of the mounting hole 811 , a shape memory alloy column 822 is installed between the inner walls of the mounting sleeve 821 , and the shape memory alloy column 822 extends through the inner walls of the infrared detector 83 .

[0042] During use of this solution, the high or low temperature inside the furnace body 2 can be input into the interior of the mounting sleeve 821 through the air vent 1 21 and the air vent 2 812. As a result, the shape memory alloy column 822 undergoes memory deformation under the influence of temperature. The deformation value of the shape memory alloy column 822 can be set and changed in advance according to the normal operating temperature of the factory furnace body 2. As a result, during normal use, the shape memory alloy column 822 undergoes deformation under the influence of temperature. At this time, one end of the shape memory alloy column 822 penetrates between the inner walls of the infrared detector 83 and does not conflict with the pressure-sensitive component 84. This is the normal operating temperature, the warning light 86 does not sound an alarm, and the infrared detector 83 can detect the presence of an object between the inner walls.

[0043] When the temperature inside the furnace body 2 is too low, the shape memory alloy column 822 does not deform and gradually returns to its initial shape. At this time, the shape memory alloy column 822 retracts to the rear side of the infrared detector 83, so that the infrared detector 83 cannot detect any object between the inner walls. The infrared detector 83 then sends a signal to the warning light 86, indicating that the temperature inside the furnace body 2 is low and that adjustments need to be made in time.

[0044] When the temperature inside the furnace body 2 is too high, the shape memory alloy column 822 extends and deforms to the limit value under the influence of temperature, thereby contacting the surface of the pressure-sensitive component 84. As a result, the pressure-sensitive component 84 sends a signal to the warning light 86, thereby notifying the outside world that the inside of the furnace body 2 is in a high temperature state and timely adjustments are required.

[0045] In this embodiment, the deformation threshold of the shape memory alloy column 822 can be replaced accordingly according to the specific operating environment and materials of the personnel, so that it is applicable to various scenarios and has a wider range. During the replacement work, the personnel only need to take out the installation sleeve 821 from the inside of the installation hole 811 and replace it.

[0046] See also Figure 3-5 The pressure sensitive component 84 includes a base 841 fixedly connected to the rear wall of the cavity, a pressure plate 842 is provided between the inner wall of the base 841, a spring 843 is fixedly connected between the pressure plate 842 and the base 841, and a pressure sensitive switch 844 is installed on the inner wall of the base 841. The pressure sensitive switch 844 is located on the center side of the spring 843.

[0047] During use, when the shape memory alloy column 822 is deformed to its limit value at high temperature, the shape memory alloy column 822 is compressed against the spring 843 and simultaneously contracts toward the inside of the base 841 until it presses against the surface of the pressure sensitive switch 844, thereby triggering a signal induction, so that the warning light 86 issues a warning reminder.

[0048] After the high temperature problem is resolved, the shape memory alloy column 822 is no longer subjected to the extreme high temperature and thus contracts a certain distance, no longer contacting the pressure plate 842. Simultaneously, the pressure plate 842 is restored by the spring 843 and no longer presses against the surface of the pressure sensitive switch 844. Therefore, the pressure sensitive switch 844 no longer issues a signal, and the warning light 86 also stops warning.

[0049] In this embodiment, a power supply and a signal receiving terminal are provided inside the power box 85 for inputting signals to the warning light 86 and supplying power to the infrared detector 83 and the pressure-sensitive component 84 .

[0050] The above-mentioned embodiments only express a certain implementation method of the utility model, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the patent of the utility model. It should be pointed out that for ordinary technicians in this field, several variations and improvements can be made without departing from the concept of the utility model, which all fall within the scope of protection of the utility model. Therefore, the scope of protection of the utility model patent shall be based on the attached claims.
