Description

Technical Field

[0001] The utility model relates to the technical field of muffle tube protection, and more specifically to a muffle tube high-temperature deformation stabilizing device. Background Art

[0002] The inside of the muffle tube is usually filled with refractory materials and is usually used in high-temperature environments such as smelting furnaces and combustion equipment. It has the characteristics of high temperature resistance, corrosion resistance, and oxidation resistance. The function of the muffle tube is to protect the heating element from oxidation at high temperatures while allowing hot gases to pass through. The muffle tube, also known as a metal bellows, is widely used in high-temperature, high-pressure, and large-flow heat medium transmission systems, such as burners, boilers, locomotive heaters, industrial furnaces, household appliances, automobile engines, and other high-temperature thermal devices.

[0003] The muffle tube high temperature deformation stabilization device is a device used to control the deformation of the muffle tube in a high temperature environment to ensure its stability.

[0004] The existing high-temperature deformation stabilization device for muffle tubes still has the following problems: the existing high-temperature deformation stabilization device is relatively cumbersome to fix muffle tubes of various sizes, and it is also difficult to maintain the shape after fixation, resulting in unsatisfactory stability;

[0005] In addition, in the process of clamping the muffle tube, most of the existing stabilizing devices use cooling water for cooling, which undoubtedly increases its maintenance cost and occupies a large area to store cooling water. The temperature of the cooling water is also difficult to control, and its cooling effect is relatively limited, which brings many inconveniences to use.

[0006] In view of this, we propose a high-temperature deformation stabilization device for muffle tubes. Utility Model Content

[0031] A muffle tube high temperature deformation stabilization device comprises a cooling seat 100, a support base 110 is arranged on the top of the cooling seat 100, a guide tube 120 is arranged on the front and rear outer walls of the cooling seat 100, a semiconductor refrigeration plate 140 is arranged at the bottom of the inner cavity of the cooling seat 100, a partition 150 and a support block 170 are arranged on the top of the semiconductor refrigeration plate 140, and a cooling vortex tube 180 is arranged on the top of the support block 170;

[0032] In some embodiments: A cooling vortex tube is a device for generating cold air and hot air, and its principle is based on the vortex effect. The cooling vortex tube is usually composed of the following parts: a mixing chamber, a generator, a spiral tube, a cold air outlet and a hot air outlet, wherein the mixing chamber is the inlet part of the cooling vortex tube, and is used to introduce compressed air into the vortex tube. The generator is a part in the mixing chamber, and is used to generate a high-speed rotating airflow. The spiral tube is the core part of the cooling vortex tube, and it is a spiral pipe with a rotating airflow inside. When high-speed airflow enters the spiral tube, a vortex effect will be generated, causing the airflow to separate into cold air and hot air in the tube. The cold air outlet and the hot air outlet are used to discharge cold air and hot air respectively. When high-pressure air enters the mixing chamber, a part of the gas will form a high-speed rotating airflow inside the spiral tube. Due to the vortex effect, this rotating airflow will be separated into cold air and hot air inside the spiral tube. The cold air will move toward the center along the inner wall of the spiral tube and eventually be discharged from the cold air outlet, while the hot air will move toward the two ends along the outer side of the spiral tube and eventually be discharged from the hot air outlet. By adjusting the pressure and flow of the inlet airflow, as well as the structure and size of the spiral tube, the generation ratio of cold air and hot air in the cooling vortex tube can be controlled, thereby achieving precise control of cold air and hot air.

[0035] Specifically, a pressing circular groove 240 is provided on the side wall of the side clamping plate 220. The pressing circular groove 240 is slightly larger than the pressing column 1, so that the threaded rod 210 can be better used to drive the side clamping plate 220 to move and adjust.

[0036] Furthermore, a second pressing circular groove 350 slightly larger than the second pressing column is provided on the top of the upper clamping plate 340, and the side clamping plate 220 and the upper clamping plate 340 are arc-shaped, so as to better fix the muffle tube.

[0037] Furthermore, a connecting block 360 is provided at the bottom of the cover plate 300 , and a fixing bolt 370 for fixing is threadedly connected to the outer wall in front of the connecting block 360 , so as to facilitate fixing of the cover plate 300 .

[0038] Furthermore, a heat sink 141 is provided at the bottom of the semiconductor refrigeration plate 140 . The heat sink 141 is made of copper to facilitate heat dissipation of the heating end of the semiconductor refrigeration plate 140 .

[0039] In some embodiments: a controller can be set externally to control the semiconductor refrigeration plate 140 for cooling, wherein the high-pressure gas source used for cooling the vortex tube can be provided by an external air pump. The semiconductor refrigeration plate 140 is a device that uses the Peltier effect to achieve refrigeration, and its principle is based on the thermoelectric effect. The controller is usually composed of a temperature sensor, a power regulator and a feedback loop, which can facilitate the control of the semiconductor refrigeration plate 140, and belongs to the prior art.

[0040] It is worth noting that a guide tube 2 130 is arranged on the top of the multiple guide tubes 120 , and the multiple guide tubes 130 are respectively connected to the front and rear outer walls of the installation shell 200 , so as to facilitate the delivery of cold air to the inside of the installation shell 200 to better cool the muffle tube.

[0041] It is worth noting that wind guide plates 160 are provided on the outer walls on both sides of the partition 150. The wind guide plates 160 are isosceles triangles, which are convenient for separating and guiding the cold air.

The tube is fixed, which can better avoid the deformation of the muffle tube. Secondly, disassembly and installation are also more convenient. When the muffle tube is in use, an external air source can be used to inject into the cooling vortex tube 180, and the vortex effect is used to generate cold air to enter the cooling seat 110. After that, the air flow is guided by the air guide plate 160 to cooperate with the semiconductor refrigeration plate 140 to cool the air again. After that, the cold air will enter the interior of the installation shell 200 along the guidance of the guide tube 120 and the guide tube 2 130 to better cool the muffle tube.
