Description

Technical Field

[0001] The utility model relates to the technical field of experimental instruments, in particular to a novel gas generator. Background Art

[0002] In laboratories, gases such as hydrogen and carbon dioxide need to be frequently prepared for chemical experiments. The Kipp generator is a commonly used gas generation device, which consists of a spherical funnel, a container (including a spherical reaction chamber and a hemispherical liquid storage chamber), and a gas pipe. It is widely used in existing middle school chemistry experiments.

[0003] In the prior art, the common Kipp generator usually adds liquid or solid reactants through an upper or side interface, which is likely to leave a certain amount of air above the liquid, thus affecting the purity of the produced gas. When some of the produced gases are used in experiments, it is necessary to test the purity before ignition, otherwise it is easy to explode and cause safety accidents. In addition, the solid and liquid are in the same container. After the experiment is interrupted or ended, the liquid must be poured out to separate from the solid. For acidic liquids, the operation of putting in and taking out is frequent, which is easy to burn clothes or damage instruments, and the operation is troublesome. Therefore, we propose a novel gas generator to solve the above problems. Summary of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a novel gas generator, which solves the problems mentioned in the above background art.

The liquid storage assembly and the solid storage assembly are respectively located on the left and right sides of the reaction cylinder. The reaction cylinder is fixedly connected to the lower sides of the liquid storage assembly and the solid storage assembly. A metal partition net is clamped inside the lower part of the reaction cylinder. A control valve three is fixedly connected to the bottom end of the reaction cylinder. A piston ring is movably sleeved inside the reaction cylinder, and the top end of the piston ring is fixedly connected to an exhaust pipe. A check valve two is fixedly installed on the top of the piston ring on one side of the exhaust pipe.

[0006] Preferably, support seats are clamped at the bottom ends of the reaction cylinder and the liquid storage assembly. A connecting pipe is fixedly connected to the side of the reaction cylinder, and a control valve one and a check valve one are arranged on the connecting pipe.

[0007] Preferably, a bearing platform matching with the metal partition net is arranged inside the reaction cylinder. The reaction cylinder communicates with the liquid storage assembly and the solid storage assembly at a position 0.5 - 1 mm above the metal partition net on the side.

[0008] Preferably, a plurality of sealing rubber rings are sleeved on the circumferential side of the piston ring, and a second control valve is arranged below the outside of the exhaust pipe.

[0009] Preferably, the liquid storage assembly includes a liquid storage cylinder, a sealing rubber plug, and a balance pipe. The liquid storage cylinder is placed on the top of a group of support seats. A sealing rubber plug is clamped on the top of the liquid storage cylinder, and the balance pipe is nested inside the sealing rubber plug.

[0010] Preferably, the solid storage assembly includes a solid storage cylinder, a sealing end cover, and a feed pipe. The solid storage cylinder is fixedly installed on the circumferential side of the reaction cylinder.

[0012] The utility model provides a novel gas generator, which has the following beneficial effects:

[0013] 1.

At the same time, before the reaction, the piston ring is at the lowest position, reducing the air inside the reaction cylinder, thereby reducing the influence of the residual air on the produced gas and improving the concentration of the produced gas.

[0014] 2. For this novel gas generator, by clamping a metal partition net inside the reaction cylinder, the solid reactant can be supported by the metal partition net. After the gas production reaction, by opening the third control valve, the liquid reactant can be discharged, and at the same time, by pulling out the piston ring, the solid reactant can be poured out, avoiding burning clothes or damaging instruments.

Specific embodiments

[0021] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

[0022] Please refer to Figure 1-2 , the present utility model provides a technical solution: a new type of gas generator, including a reaction cylinder 1, a liquid storage assembly 2, and a solid storage assembly 3. The liquid storage assembly 2 and the solid storage assembly 3 are respectively located on the left and right sides of the reaction cylinder 1. The reaction cylinder 1 is fixedly connected and communicated with the lower sides of the liquid storage assembly 2 and the solid storage assembly 3. A metal partition net 12 is clamped inside the lower part of the reaction cylinder 1. The solid reactant is supported by the metal partition net 12. After gas production, by opening the control valve III 13, the liquid reactant can be discharged. At the same time, by pulling out the piston ring 9, the solid reactant can be poured out. The bottom end of the reaction cylinder 1 is fixedly connected with a control valve III 13. A piston ring 9 is movably sleeved inside the reaction cylinder 1. Before the reaction, the piston ring 9 is located at the lowest position, reducing the air inside the reaction cylinder 1, thereby reducing the influence of the residual air on the produced gas and improving the concentration of the produced gas. And the top end of the piston ring 9 is fixedly communicated with an exhaust pipe 8. By pulling the piston ring 9 upward through the exhaust pipe 8, the liquid reactant in the liquid storage assembly 2 can be extracted by negative pressure, and the extrusion plate 33 can be driven to move downward by the adjusting screw 34 to extrude the solid reactant and put the solid reactant into the reaction cylinder 1. A check valve II 15 is fixedly installed on the top of the piston ring 9 on one side of the exhaust pipe 8. When the exhaust pipe 8 drives the piston ring 9 to move downward, the control valve II 11 is opened, and the gas can be exhausted along the exhaust pipe 8. When the control valve II 11 is closed, the gas can be exhausted along the check valve II 15.

[0023] Please refer to Figure 2, a support base 14 is clamped to the bottom ends of the reaction cylinder 1 and the liquid storage assembly 2. The reaction cylinder 1 and the liquid storage assembly 2 are supported by the support base 14 to ensure the stability of the reaction cylinder 1 and the liquid storage assembly 2 during operation. A connecting pipe 4 is fixedly connected to the side of the reaction cylinder 1, and a control valve 5 and a one-way valve 6 are arranged on the connecting pipe 4. The opening and closing of the connecting pipe 4 can be controlled by setting the control valve 5. At the same time, by setting the one-way valve 6, the liquid can only enter the inside of the reaction cylinder 1 from the liquid storage assembly 2. A connecting head is arranged on the liquid storage assembly 2, and the connecting pipe 4 is connected to the connecting head through a rubber sleeve 7, which facilitates the disassembly and assembly of the liquid storage assembly 2 and the reaction cylinder 1 and reduces the operation difficulty at the same time.

[0024] Please refer to Figure 2 , Figure 5 , a bearing platform matching with the metal mesh 12 is arranged inside the reaction cylinder 1. The metal mesh 12 is restricted by the bearing platform to prevent the metal mesh 12 from falling, ensuring that the metal mesh 12 can stably support the solid reactants. The side of the reaction cylinder 1 is connected to the liquid storage assembly 2 and the solid storage assembly 3 at a position 0.5 - 1 mm above the metal mesh 12, restricting the connection position of the reaction cylinder 1, the liquid storage assembly 2, and the solid storage assembly 3, ensuring that the piston ring 9 can move to the lower part inside the reaction cylinder 1 and preventing the residual air from affecting the experiment.

[0025] Please refer to Figure 3 , a number of sealing rubber rings 10 are sleeved on the circumferential side of the piston ring 9, and a control valve 11 is arranged below the outside of the exhaust pipe 8. When the exhaust pipe 8 drives the piston ring 9 to move downward, the control valve 11 is opened, and the gas can be exhausted along the exhaust pipe 8. When the control valve 11 is closed, the gas can be exhausted along the one-way valve 15.

[0026] Please refer to Figure 2 , the liquid storage assembly 2 includes a liquid storage cylinder 21, a sealing rubber plug 22, and a balance pipe 23. The liquid storage cylinder 21 is placed on the top of a group of support bases 14, a sealing rubber plug 22 is clamped to the top of the liquid storage cylinder 21, and the balance pipe 23 is nested inside the sealing rubber plug 22. By setting the balance pipe 23, the internal and external air pressures of the liquid storage cylinder 21 are balanced, ensuring that the piston ring 9 can draw the liquid reactants along the connecting pipe 4 when moving upward.

[0027] Please refer to Figure 2 , Figure 5 , the solid storage assembly 3 includes a solid storage cylinder 31, a sealing end cover 32, and a feed pipe 35. The solid storage cylinder 31 is fixedly installed on the circumference of the reaction cylinder 1, a sealing end cover 32 is threadedly connected to the top of the solid storage cylinder 31, and a feed pipe 35 is fixedly connected to the bottom. The solid reactants inside the solid storage cylinder 31 can be introduced into the reaction cylinder 1 along the feed pipe 35, enabling the liquid and the solid reactants to come into contact and react.

[0028] The solid storage assembly 3 further includes an extrusion plate 33 and an adjustment screw 34. The adjustment screw 34 is threadedly connected to the middle of the sealing end cap 32. The bottom end of the adjustment screw 34 is movably connected to the extrusion plate 33. By driving the extrusion plate 33 to move downward through the adjustment screw 34, the solid reactant is extruded, and the solid reactant is put into the reaction cylinder 1 along the feed pipe 35, so that the liquid and the solid reactant can react.

[0029] In summary, for this new type of gas generator, during use, the liquid reactant required for gas production is introduced into the liquid storage cylinder 21, and the solid reactant required for gas production is introduced into the solid storage cylinder 31. The sealing end cap 32 is threadedly connected to the end of the solid storage cylinder 31. The adjustment screw 34 is rotated to drive the extrusion plate 33 to move downward, pressing the solid reactant tightly and discharging the air in the solid storage cylinder 31. At this time, the piston ring 9 is at the lowest position, and the piston ring 9 can block the feed pipe 35. When adjusting the position of the piston ring 9, the piston ring 9 is driven to move downward through the exhaust pipe 8, and the air inside the reaction cylinder 1 is discharged upward through the check valve II 15; during the reaction, the piston ring 9 is driven to move upward through the exhaust pipe 8, and the liquid reactant inside the liquid storage cylinder 21 is extracted along the connecting pipe 4 by negative pressure. At the same time, the adjustment screw 34 is rotated to drive the extrusion plate 33 to move downward, extruding the solid reactant, and the solid reactant is introduced onto the top of the metal mesh 12 along the feed pipe 35, so that the liquid reactant and the solid reactant react to generate the required gas; after the reaction, the control valve III 13 is opened to discharge the liquid reactant, the piston ring 9 is taken out, and the solid reactant is poured out, and that's it.
