Description

Technical Field

[0001] The utility model relates to the technical field of metal smelting, in particular to a device for non-melting fume volatilization of tin. Background Art

[0002] Tin is a metallic element, an inorganic substance, mainly used to make alloys, such as lead-tin alloy can be used as solder, copper-tin alloy is bronze, and it can also be used as tin foil and metal plating. When metal minerals contain tin and the tin needs to be collected, the minerals are often heated. When the tin is heated to a high temperature, it will fume and volatilize, and the sublimated tin gas will be cooled and collected.

[0003] At the same time, in order to study the volatility of tin at high temperatures rather than its melting properties, the non-melting fuming volatilization experiment can be used to explore the process of tin directly transforming from solid to gas under high temperature conditions.

[0004] When conducting non-melting fume volatilization experiments on tin, in order to prevent the tin from melting, the heating temperature of the tin needs to be strictly controlled. When the tin is heated at different altitudes, the melting point of the tin will fluctuate due to the influence of atmospheric pressure changes. At this time, when the tin is heated according to the melting point temperature of tin, it is easy to cause the tin to melt, resulting in the inability to study the volatility properties of tin normally.

DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] When tin is volatilized by fuming, the melting point of tin is about 232 degrees Celsius under standard atmospheric pressure. When ensuring that it does not melt, the temperature needs to be as close to the melting point of tin as possible. At this time, when the atmospheric pressure changes with the altitude, it is easy to cause the tin to melt, affecting the staff's observation of the volatility of tin at high temperatures. In a low-pressure environment, the collision frequency between gas molecules is low, causing the sublimation rate of the solid substance to exceed the solidification rate, thereby causing the solid substance to directly transform into a gaseous state, effectively helping the tin to volatilize without melting.

[0023] like Figure 1-Figure 5As shown, the utility model provides a technical solution: a non-melting fume volatilization tin device, comprising a bottom plate 1 and a main box 3 fixedly connected to the top outer wall of the bottom plate 1, characterized in that a cabinet door 2 is hingedly connected to one side outer wall of the main box 3, and a flowing water component 5 for cooling tin vapor is fixedly connected to the top of the main box 3, and a cooling component 7 for collecting tin is fixedly connected between the inner walls on both sides of the top of the main box 3, and an exhaust component 6 for reducing the pressure of the main box 3 is fixedly connected to the outer wall at one end of the main box 3;

[0024] The exhaust assembly 6 includes a mounting plate and an air intake pipe 602, and the mounting plate is fixedly connected to the outer wall of one end of the main box 3, the air intake pipe 602 is fixedly connected between the main box 3 and the mounting plate, the outer wall of the other end of the mounting plate is fixedly connected to an exhaust pump 601 that is in communication with the air intake pipe 602, and a flow limiting assembly that prevents gas backflow is fixedly connected between the circumferential inner walls of the air intake pipe 602.

[0025] It should be noted that: when the exhaust pump 601 is started, the air inside the main box 3 will be sucked out through the suction pipe 602, so that the inside of the main box 3 will be in a low-pressure state. When the volatilized tin enters the cooling component 7, the cooling component 7 is cooled by the flowing water component 5, so that the sublimated tin can be cooled and collected.

[0026] like Figure 5 The current limiting assembly includes a fixed ring 609, and the fixed ring 609 is fixedly connected to the circumferential inner wall of the suction pipe 602, a plurality of cross bars 605 are fixedly connected to the outer wall of one end of the fixed ring 609, and a fixed rod 603 is fixedly connected between the outer walls of the other ends of the cross bars 605, a moving rod 606 is slidably sleeved between the circumferential outer walls of the cross bars 605, and a plurality of return springs 606 sleeved on the circumferential outer walls of the cross bars 605 are fixedly connected between the moving rod 606 and the fixed rod 603. 04. The outer wall at one end of the moving rod 606 is fixedly connected with a moving plate 610, and the moving plate 610 is sealed and inserted between the outer walls at both ends of the fixed ring 609. The outer walls at one end of the fixed ring 609 and the moving plate 610 are respectively fixedly connected with a protective ring 607 and a protective plate 608. The top inner wall of the main box 3 is fixedly connected with a horizontal plate, and the bottom outer wall at one end of the horizontal plate is fixedly connected with an inclined plate 11. A plurality of through holes equidistantly distributed are provided between the outer walls at both ends of the bottom of the inclined plate 11.

[0027] It should be noted that: when the exhaust pump 601 is working, a negative pressure state will be generated at one end of the intake pipe 602. At this time, the gas inside the main box 3 will press the movable plate 610 open and discharge the gas through the intake pipe 602. When the inside of the main box 3 is in a negative pressure state, under the pressure of the return spring 604, the movable plate 610 will be pressed back into the fixed ring 609 to keep the inside of the main box 3 in a negative pressure state. The material of the protective ring 607 and the protective plate 608 is glass, which has strong heat resistance and can prevent heat conduction from causing damage to the internal components of the intake pipe 602.

[0028] like Figure 2 A heating base 10 is fixedly connected to the middle position of the top outer wall of the bottom plate 1, and a control panel electrically connected to the heating base 10 and the exhaust pump 601 is fixedly connected to the outer wall of one end of the main box 3, a partition 9 is fixedly connected between the inclined plate 11 and the inner walls around the main box 3, and a guide tube 8 is fixedly connected between the partition 9 and the horizontal plate.

[0030] like Figure 3-Figure 4 The cooling component 7 includes a sleeve 704, and the sleeve 704 is fixedly connected between the top of the horizontal plate and the inner wall of one end of the main box 3, the bottom circumferential inner wall of the sleeve 704 is fixedly connected with a vertical pipe 706, and the circumferential inner wall of one end of the vertical pipe 706 is fixedly connected with an inner ring 705, the circumferential outer wall of the inner ring 705 is sleeved with an inner pipe 701, and the circumferential outer wall of one end of the inner pipe 701 is fixedly connected with an adsorption ring 702, the outer wall of one end of the sleeve 704 is fixedly connected with a docking ring 703 matched with the adsorption ring 702, and the outer wall of the other end of the inner pipe 701 is fixedly connected with a sealing ring 707 that is in sealing contact with the vertical pipe 706.

[0031] It should be noted that the volatilized tin vapor will enter the interior of the vertical pipe 706 through the guide tube 8, and the external water will flow through the water inlet pipe 502 and the drain pipe 501 on the top of the main box 3 to cool the sleeve 704. The tin vapor entering the vertical pipe 706 and the inner tube 701 will condense into liquid and cool into solid under the action of the sleeve 704, thereby achieving the collection effect of tin. The adsorption ring 702 and the docking ring 703 are heterogeneous magnet structures, which can make the inner tube 701 firmly inserted into the sleeve 704. When the tin needs to be recovered, the inner tube 701 can be taken out and the tin can be recovered. The sealing ring 707 can prevent the negative pressure state in the main box 3 from being affected.

[0032] Working principle: When the exhaust pump 601 is working, a negative pressure state will be generated at one end of the suction pipe 602. At this time, the gas inside the main box 3 will press the movable plate 610 open and discharge the gas through the suction pipe 602. When the inside of the main box 3 is in a negative pressure state, under the pressure of the return spring 604, the movable plate 610 will be pressed back into the fixed ring 609 to keep the inside of the main box 3 in a negative pressure state. When the volatilized tin enters the cooling component 7, the cooling component 7 is cooled by the flowing water component 5, so that the sublimated tin can be cooled and collected. The volatilized tin vapor will enter the vertical pipe 706 through the guide tube 8, and the external water will flow on the top of the main box 3 through the water inlet pipe 502 and the drain pipe 501 to cool the sleeve 704. The tin vapor entering the vertical pipe 706 and the inner tube 701 will condense into liquid and cool into solid under the action of the sleeve 704. When the tin needs to be recovered, the inner tube 701 can be taken out and the tin can be recovered.
