Technical Field

[0001] This utility model belongs to the field of waste gas collection technology, and specifically relates to a waste gas collection bottle. Background Technology

[0002] Waste gas testing involves using specialized technical methods to analyze the composition of industrial waste gases. The purpose is to determine whether the waste gases meet national emission standards and prevent pollutants from harming the environment and human health. Waste gas collection bottles are used for collection. Existing waste gas collection bottles have a relatively simple structure, typically consisting of a bottle body, a cap, and two connecting tubes of different lengths. After the waste gas enters the bottle, the two connecting tubes and the bottle opening are sealed only by a sealing plug. This single sealing method results in poor sealing performance and therefore needs improvement. Utility Model Content

Detailed Implementation

[0025] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0026] like Figure 1-5 As shown, this utility model provides a waste gas collecting bottle, comprising:

[0027] Bottle body 1, with an assembly tube 11 at the top, a sealing cap 12 threaded around the periphery of the assembly tube 11, and a sealing gasket 13 at the bottom of the sealing cap 12; bottle body 1 is a transparent bottle body.

[0028] Arc-shaped frame 2 is fixedly installed on the upper side inside the bottle body 1;

[0029] The sealing plate 3 is slidably and sealingly assembled inside the arc frame 2. The top of the sealing plate 3 has two through holes 31 distributed on the left and right. The bottom of the sealing plate 3 is fixedly installed with two connecting pipes 32 that match the positions of the two through holes 31.

[0030] The drive mechanism 4 is installed inside the upper side of the bottle body 1 and is used to drive the sealing plate 3 to rotate. Specifically, the drive mechanism 4 includes a rotating shaft 41. A mounting through hole is opened on the top right side of the bottle body 1. The rotating shaft 41 is rotatably and sealingly assembled inside the mounting through hole. A sliding groove 42 is opened on the right side of the arc frame 2. A connecting block 43 that is slidably connected to the sliding groove 42 is fixedly installed on the right side of the sealing plate 3. One end of the connecting block 43 is fixedly connected to the periphery of the rotating shaft 41. A screw block 44 is fixedly installed on the upper end of the rotating shaft 41. A locking component is provided between the screw block 44 and the bottle body 1.

[0031] When waste needs to be collected, the first connecting pipe 5 or the second connecting pipe 6 is selected as the inlet pipe according to the density of the waste gas, while the other pipe is the outlet pipe. In the initial state, the first connecting pipe 5 and the second connecting pipe 6 are respectively matched with the two connecting pipes 32. The staff can directly collect the waste gas into the bottle 1. After collection, the first connecting pipe 5 and the second connecting pipe 6 are sealed at the outer end of the bottle 1 using a sealing plug. Then, the staff releases the locking component from the locking block 44, rotates the locking block 44 by a certain angle, and the locking block 44 drives the connecting block 43 to rotate by a small angle and locks it using the locking component. This causes the first connecting pipe 5 and the second connecting pipe 6 to be staggered with the two connecting pipes 32, using two sealing pads. 7. By sealing the two through holes 31, the sealing plate 3 seals the assembly tube 11, the first connecting tube 5, and the second connecting tube 6. With the cooperation of the sealing gasket 13 and the external sealing plug, the assembly tube 11, the first connecting tube 5, and the second connecting tube 6 can be double-sealed, improving the sealing effect. When the gas is removed later, the sealing plate 3 can be restored to its original position. The operation is simple and convenient. The sealing plate 3 and the rotating shaft 41 are non-removable components, so the existing rotational sealing and sliding sealing technologies can be used for effective sealing. When it is necessary to clean the inside of the bottle 1, the sealing plate 3 can be rotated to the maximum angle, so that the assembly tube 11 can be completely connected to the inside of the bottle 1, which facilitates subsequent cleaning. The operation is simple and convenient.

[0032] The locking assembly includes an assembly block 45, which is fixedly installed on the top right side of the bottle body 1. A threaded through hole is provided on the right side of the assembly block 45, and a bolt 46 is threadedly connected inside the threaded through hole. Several threaded holes are provided around the screw block 44, and the bolt 46 is threadedly connected to one of the threaded holes.

[0033] When tightening the screw block 44, rotate the bolt 46 so that the thread 46 connects with the threaded hole to be aligned, and the tightening is completed. When it is necessary to rotate the screw block 44 later, rotate the bolt 46 to disengage it from the threaded hole. The threaded hole on the periphery of the screw block 44 makes it easy to limit and fix the screw block 44 at different angles.

[0034] The first connecting pipe 5 is installed on the top left side of the closed cover 12, and the lower end of the first connecting pipe 5 matches the position of the left through hole 31.

[0035] The second connecting pipe 6 is installed on the top right side of the closed cover 12, and the lower end of the second connecting pipe 6 matches the position of the right through hole 31.

[0036] There are two sealing pads 7. The two sealing pads 7 are fixedly installed on the lower side of the periphery of the first connecting pipe 5 and the second connecting pipe 6 respectively. The bottom of the two sealing pads 7 abuts against the top of the sealing plate 3.

[0037] A first standard line 8 is provided on the top left side of the bottle body 1, and a second standard line 81 is provided on the left side of the periphery of the sealing cap 12, which matches the position of the first standard line 8. When installing the sealing cap 12, the sealing cap 12 is rotated to connect with the assembly tube 11. The final state is such that the first standard line 8 and the second standard line 81 are aligned, which is the standard installation state. The sealing gasket 13 is aligned with the connection between the assembly tube 11 and the sealing cap 12, and the first connecting tube 5 and the second connecting tube 6 are respectively aligned with the positions of the two connecting tubes 32.

[0038] The device is used as follows:

[0039] When exhaust gas collection is required, after the sealing cover 12 is installed, in the initial state, the sealing plate 3 seals the assembly pipe 11. The area of ​​the sealing plate 3 is larger than the bottom area of ​​the assembly pipe 11. The first connecting pipe 5 and the second connecting pipe 6 are respectively aligned with the two connecting pipes 32. Based on the density of exhaust gas relative to air, the first connecting pipe 5 or the second connecting pipe 6 is selected as the inlet pipe or the outlet pipe, respectively, to collect the exhaust gas into the bottle body 1. Subsequently, rotating the screw block 44 can drive the sealing plate 3 to rotate a certain angle, continuing to seal the assembly pipe 11 while simultaneously aligning the first connecting pipe 5 with the second connecting pipe 32. The two connecting pipes 6 are misaligned with the two connecting pipes 32, and the two sealing gaskets 7 seal the two through holes 31 respectively. In this way, the first sealing of the first connecting pipe 5, the second connecting pipe 6 and the assembly pipe 11 can be completed by the cooperation of the sealing plate 3 and the two sealing gaskets 7. The ends of the first connecting pipe 5 and the second connecting pipe 6 are sealed a second time by the external sealing plug, and the connection between the assembly pipe 11 and the sealing cover 12 is sealed a second time by the sealing gasket 13. The double sealing effectively improves the sealing effect, avoids air leakage or mixing with the outside gas, and effectively improves the accuracy of the detection effect.

Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
