Description

Technical Field

[0001] The utility model relates to the technical field of laboratory instruments, in particular to an anti-corrosion interception bottle. Background Art

[0002] In laboratory work, when analyzing and filtering various aqueous solutions, organic solutions and corrosive liquids, in order to accelerate the flow of liquids, it is necessary to use the vacuum power source, that is, the diaphragm vacuum pump, to generate negative pressure. It can be seen that the diaphragm vacuum pump is an essential experimental equipment in the laboratory.

[0003] However, the pump body of the diaphragm vacuum pump cannot be immersed in any liquid of any nature, otherwise it will cause experimental accidents, resulting in the destruction of experimental data and property losses. At present, the main method is to isolate the liquid from entering the pump body by using an interception bottle, but the existing interception bottle has poor sealing at the bottle cap, which makes it easy for the liquid to penetrate into the pump body. Secondly, the anti-corrosion ability of the bottle body and bottle cap is low and cannot meet the anti-corrosion requirements. Utility Model Content

[0020] The utility model provides an anti-corrosion interception bottle, such as Figure 1-3 As shown, it includes a bottle body 1, a bottle cap 2, an air inlet pipe 3, a intercepting pipe 4, a float 5, two vent pipes 6, and an inner liner 8. The inner liner 8 is embedded in the bottle cap 2, and the bottle cap 2 is provided with a vent 7 connected to the two vent pipes 6. The two vent pipes 6 are used for air intake and air outlet, and the vent pipe 6 at one end of the air outlet is connected to a diaphragm vacuum pump. The side of the inner liner 8 is provided with an upper screw port 9 connected to the vent port 7, and the end of the vent pipe 6 is provided with a threaded tube adapted to the upper screw port 9. When the vent pipe 6 is connected, it is inserted into the vent port 7 and threadedly connected to the upper screw port 9. The bottle cap 2 is connected to the bottle body 1 by a thread.

[0021] An annular boss 14 is provided at the bottom of the intercepting pipe 4 .

[0022] The bottom of the inner tank 8 is provided with a lower screw hole 10 for connecting the air inlet pipe 3 and the intercepting pipe 4, and the top of the air inlet pipe 3 and the intercepting pipe 4 is provided with a threaded pipe adapted to the lower screw hole 10. The air inlet pipe 3 is shorter than the intercepting pipe 4, and the bottom ends of the air inlet pipe 3 and the intercepting pipe 4 are both through.

[0023] like Figure 3As shown, an air hole 15 is provided on the upper side of the intercepting pipe 4. After the gas is discharged from the bottom end of the air inlet pipe 3, it enters the intercepting pipe 4 through the air hole 15. The float 5 is arranged in the intercepting pipe 4. The float 5 can slide vertically in the intercepting pipe 4 by buoyancy. A plug 13 is arranged on the top of the float 5. When the plug 13 blocks the air hole 15, the liquid level in the bottle body 1 is slightly lower than the bottom end surface of the air inlet pipe 3. The liquid in the bottle body 1 is prevented from being brought into the air hole 15.

[0024] like Figure 2 As shown, in order to improve the sealing between the bottle cap 2 and the bottle body 1, and the sealing between the air inlet pipe 3, the intercepting pipe 4 and the inner liner 8, a sealing ring 11 is arranged between the inner liner 8 and the top surface of the bottle body 1 to improve the sealing of the connection between the inner liner 8 and the bottle body 1. A sealing ring 2 12 is arranged between the air inlet pipe 3, the intercepting pipe 4 and the lower screw port 10 to improve the sealing of the connection between the air inlet pipe 3, the intercepting pipe 4 and the inner liner 8.

[0025] Since the gas used in the experiment is corrosive, the two ventilation pipes 6, the inner liner 8, the air inlet pipe 3, the intercepting pipe 4, the float 5, the inner liner 8, the sealing ring 1 11, and the sealing ring 2 12 are made of polytetrafluoroethylene to improve the overall corrosion resistance of the intercepting bottle and extend the service life. The bottle body 1 is made of high borosilicate glass to improve the corrosion resistance of the bottle body 1.

[0026] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
