Description

Technical Field

[0001] This utility model relates to the field of reaction vessel technology, and in particular to a high-temperature enamel-lined glass reaction vessel. Background Technology

[0002] Enameled reactors are made by lining the inner surface of a steel container with glass containing high silica content. After being fired at high temperature, the glass is firmly bonded to the metal surface, forming a composite material product. It has the stability of glass and the strength of metal, is suitable for various acid and alkali environments, and has strong corrosion resistance.

[0003] In the existing technology, the enamel layer of the enamel-lined glass reactor is brittle and prone to cracking under thermal shock, resulting in a short lifespan. If it is to be used for a long time, the time and interval of thermal shock must be adjusted. This is inconvenient for actual use. When stirring the contents of the reactor, the material rotates in the same direction as the blades, which cannot form a mixed flow and cannot achieve uniform stirring of the material. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a high-temperature enamel-lined glass reactor, which has the advantages of high tensile strength, enhanced thermal shock resistance, and uniform stirring, thus solving the problems mentioned in the background section.

[0005] This utility model provides the following technical solution: a high-temperature enamel-lined glass reactor, comprising a reactor body, a reactor cover fixedly installed on one side of the reactor body, a protective sleeve fixedly installed in the middle of the reactor cover, a feed inlet uniformly arranged in a circular shape on the surface of the reactor cover around the outer ring of the protective sleeve, a discharge outlet symmetrically arranged at the end of the reactor, a support symmetrically arranged at the bottom of the reactor, a groove provided inside the reactor cover corresponding to the position of the protective sleeve, a rotating device rotatably installed inside the reactor, the rotating device rotatably installed on the outer ring of the groove, and an enamel layer uniformly coated on the inner walls of the reactor body and the reactor cover.

[0006] With the above structural design, in actual use, the magnetic drive shaft of the external motor is inserted into the groove. The magnetic drive shaft drives the rotating device to rotate together with the rotating device by the principle of repulsion between the like poles of the magnetic drive shaft and the rotating device. This ensures that the material in the reactor will not leak due to poor sealing of the stirring device during stirring.

[0007] Preferably, the rotating device has a magnetic rotor located on the inner wall of the outer ring end of the groove. The outer ring of the rotating device is uniformly fixed with a stirring rod. The outer ring of the stirring rod is rotatably sleeved with a rotating blade. When the rotating blade rotates, its edge will fit against the inner wall of the enamel layer.

[0008] With the above-mentioned structural design, the rotating blade can scrape off the material adhering to the inner wall of the enamel layer during rotation. While the rotating device drives the stirring rod to revolve, the rotating blade can rotate on its own axis due to the resistance of the material. With the cooperation of the stirring rod and the rotating blade, the material inside the reactor can be uniformly stirred.

[0009] Preferably, the interior of the enamel layer is uniformly provided with reinforcing wires in a circular pattern, and the interior of the enamel layer is uniformly provided with annular steel wires in a linear array. The annular steel wires and the reinforcing wires form a wire mesh, and the outer ring of the enamel layer is provided with threaded grooves.

[0010] With the above structural design, reinforcing wires and annular steel wires are embedded inside the enamel layer to form a metal mesh skeleton, which is used to resist thermal shock between high and low temperatures and prevent the enamel layer from cracking.

[0011] Preferably, the inner wall of the vessel is provided with a threaded protrusion, the enamel layer is located on the outer surface of the threaded protrusion, the enamel layer is fitted with the threaded protrusion, and the threaded groove is adapted to the threaded protrusion.

[0012] With the above structural design, by setting threaded protrusions on the inner wall of the kettle, the enamel layer can generate pre-compression stress during firing, which enhances the thermal shock resistance of the enamel layer and makes it perform better in actual work.

[0013] This utility model has the following advantages:

[0014] 1. This enamel-lined high-temperature reactor enhances tensile strength by incorporating a reactor, enamel layer, and threaded grooves. Since materials generate high temperatures during reaction and stirring, the inner wall of a conventional reactor may not withstand the impact of high and low temperatures. The enamel layer incorporates reinforcing wires and annular steel wires, thereby increasing its tensile strength and resistance to thermal shock. The inner wall of the reactor features threaded protrusions that work in conjunction with the enamel layer, enhancing its thermal shock resistance during operation and extending its service life, thus improving its overall strength.

[0015] 2. This enamel-lined high-temperature reactor achieves uniform material mixing through a protective sleeve, a rotating device, and rotating blades. First, the magnetic drive shaft of the external motor is inserted into the protective sleeve, causing it to repel the magnetic rotor on the inner ring of the rotating device. Then, the external motor is started, and the magnetic drive shaft drives the rotating device to rotate on the outer ring of the groove. The rotating device first drives the stirring rod to mix the material. Due to the resistance of the material, the rotating blades rotate on the outer ring of the stirring rod. The material is uniformly mixed by the cooperation of the stirring rod and the rotating blades, achieving a uniform mixing effect. Attached Figure Description

[0021] 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.

[0022] Please see Figures 1-2 A high-temperature enamel-lined glass reactor includes a reactor 1, which includes a reactor body 11. A reactor cover 12 is fixedly installed on one side of the reactor body 11, and a protective sleeve 13 is fixedly installed in the middle of the reactor cover 12. A feed inlet 14 is uniformly arranged in a circular shape on the surface of the reactor cover 12 around the outer ring of the protective sleeve 13. A discharge outlet 15 is symmetrically arranged at the end of the reactor 1. A support 16 is symmetrically arranged at the bottom of the reactor 1. A groove is provided inside the reactor cover 12 at the position corresponding to the protective sleeve 13. A rotating device 2 is rotatably installed inside the reactor 1. The rotating device 2 is rotatably installed on the outer ring of the groove. The inner walls of the reactor body 11 and the reactor cover 12 are uniformly coated with an enamel layer 3.

[0023] In actual use, the magnetic drive shaft of the external motor is inserted into the groove. The magnetic drive shaft drives the rotating device 2 to rotate together with the rotating device 2 by the principle of repulsion between the same poles. This prevents leakage of the material in the reactor 1 due to poor sealing of the stirring device. As the rotating device 2 drives the stirring rod 21 to rotate and stir the material, the rotating blade 22 will rotate on its own due to the resistance of the material, located on the outer ring of the stirring rod 21, thus realizing stirring of the material in multiple ranges.

[0024] Please see Figures 1-3The rotating device 2 is equipped with a magnetic rotor on the inner wall of the outer ring end of the groove. The rotating device 2 is driven to rotate by the magnetic drive shaft. The outer ring of the rotating device 2 is uniformly fixed with a stirring rod 21. The outer ring of the stirring rod 21 is rotatably sleeved with a rotating blade 22. When the rotating blade 22 rotates, its edge will fit against the inner wall of the enamel layer 3. It can scrape off the material adhering to the inner wall of the enamel layer 3 during the rotation. At the same time, the rotating device 2 drives the stirring rod 21 to revolve. Due to the resistance of the material, the rotating blade 22 can rotate on its own at the outer ring of the stirring rod 21. With the cooperation of the stirring rod 21 and the rotating blade 22, the material inside the reactor 1 is uniformly stirred.

[0025] Please see Figures 1-4 The inner wall of the vessel body 11 is provided with a threaded protrusion. The enamel layer 3 is located on the outer surface of the threaded protrusion and is fitted into the threaded protrusion. The interior of the enamel layer 3 is provided with reinforcing wires 31 in a circular pattern. The interior of the enamel layer 3 is provided with annular steel wires in a linear array. The annular steel wires and reinforcing wires 31 form a wire mesh to improve the tensile strength of the enamel layer 3. The reinforcing wires 31 are only arranged in annular pattern in the figure. In practical applications, the density of reinforcing wires 31 can be increased, or the annular wire mesh can be added to cooperate with the stirring rod 21 to improve the overall structural stability of the enamel layer 3. The outer ring of the enamel layer 3 is provided with a threaded groove 32, which is adapted to the threaded protrusion. In fact, the enamel layer 3 is a coating layer. When manufacturing this device, it is only necessary to apply the enamel layer 3 evenly to the surface of the threaded protrusion. After uniform coating, the state shown in the figure is formed.

[0026] Reinforcing wires 31 and annular steel wires are implanted inside the enamel layer 3 to form a metal mesh skeleton to resist thermal shock between high and low temperatures and prevent the enamel layer 3 from cracking. By setting threaded protrusions on the inner wall of the kettle body 11, the enamel layer 3 can generate pre-compression stress during firing, which enhances the thermal shock resistance of the enamel layer 3 and makes it more effective in actual work.

[0027] Working principle: In actual operation, the magnetic drive shaft of the external motor is first inserted into the protective sleeve 13 until it reaches the inside of the groove, causing it to repel the magnetic rotor of the inner ring at the end of the rotating device 2. At this time, the external motor is started, and the magnetic drive shaft drives the rotating device 2 to rotate on the outer ring of the groove. This avoids leakage of the stirred material from the gaps due to poor sealing of the stirring device in conventional reactors, ensuring the safety of this device during use. Then, the material is added into the reactor 1 through the feed port 14. The rotating device 2 first drives the stirring rod 21 to mix and stir the material. 22 Due to the resistance of the material, the outer ring of the stirring rod 21 will rotate. The material is uniformly mixed by the cooperation of the stirring rod 21 and the rotating blade 22. Since the material will generate high temperature during reaction and stirring, the inner wall of the conventional reaction vessel may not be able to withstand the impact between high temperature and low temperature. Because the enamel layer 3 has reinforcing wires 31 and annular steel wires embedded inside, the tensile strength and thermal shock resistance of the enamel layer 3 are improved. The inner wall of the vessel body 11 is provided with threaded protrusions that cooperate with the enamel layer 3. During operation, the thermal shock resistance of the enamel layer 3 can be enhanced, and the service life of the enamel layer 3 is extended.
