Description

Technical Field

[0001] The present application relates to the field of environmental monitoring products, and more specifically, to an automatic exhaust and leaching device. Background Art

[0002] As the pace of life accelerates, the amount of domestic waste generated by people also increases. In order to meet the needs of protecting the environment and optimizing air quality, people's domestic waste needs to be disposed of in a timely manner. Among them, solid waste may contain toxic components, and testers are required to conduct toxicity tests on solid waste samples.

[0003] When inspectors conduct leaching toxicity pretreatment on solid waste samples, they need to perform leaching operations on the solid waste. The leaching bottle is generally a 2L wide-mouth bottle with a screw cap and an inner cap. The inspectors place the solid waste sample to be tested in the leaching bottle, add the leaching agent, and then cover the inner cap and screw cap tightly. The leaching bottle is fixed on the flip oscillation device for leaching for 18±2h. During the oscillation process, gas will be generated in the bottle, and the inspectors need to open the leaching bottle regularly to release the pressure.

[0004] However, due to the excessive pressure in the extraction bottle, the inner cover will directly burst open, endangering the personal safety of the inspectors, and releasing the pressure during the oscillation requires stopping the oscillation device, which is troublesome and time-consuming.

[0005] Based on this, how to design an extraction bottle that is easy to extract the toxicity of solid waste samples to facilitate experimenters to perform safe and fast solid waste sample extraction operations is a problem that needs to be solved. Utility Model Content

[0006] In view of the above problems, the present application provides an automatic exhaust leaching device to facilitate experimenters to perform safe and fast solid waste sample leaching operations.

[0007] In order to achieve the above objectives, the specific plan is proposed as follows:

[0008] An automatic exhaust leaching device comprises a manual ball valve, an automatic exhaust valve, a bottle cap and a bottle body, wherein the automatic exhaust valve and the bottle cap are mounted on the top of the bottle body in an upright state, and the manual ball valve is connected to the bottle body through the automatic exhaust valve;

[0009] The automatic exhaust valve includes a valve core, so that when the bottle body is in an inverted state, the valve core separates the space inside the bottle body from the external space under the action of gravity, and when the bottle body returns to an upright state, the valve core resumes connecting the space inside the bottle body with the external space.

[0010] Preferably, the first column of the automatic exhaust valve is connected to the second column through a spherical cover, the spherical cover is equipped with the valve core, and the automatic exhaust valve further includes a support column;

[0011] The first column rod is connected to the manual ball valve, and the second column rod is connected to the bottle body;

[0012] The support column is arranged in the spherical cover at the side of the second column rod, so that when the bottle body is upright, there is a gap between the valve core and the second column rod under the action of gravity, so as to connect the space in the bottle body with the external space;

[0013] There is no supporting structure in the spherical cover and on the side of the first column, so that when the bottle body is inverted, the valve core is completely fitted with the first column under the action of gravity to isolate the space inside the bottle body from the external space.

[0014] Preferably, the first column of the automatic exhaust valve is connected to the second column through a spherical cover, and the valve core is built in the spherical cover;

[0015] The first column rod is connected to the manual ball valve, and the second column rod is connected to the bottle body;

[0016] The curvature of the valve core on the side of the second column is inconsistent with the curvature of the spherical cover, so that when the bottle body is upright, the valve core does not completely fit with the second column under the action of gravity, so as to connect the space inside the bottle body with the external space;

[0017] The curvature of the valve core on the side of the first column is the same as that of the spherical cover, so that when the bottle body is inverted, the valve core is completely fitted with the first column under the action of gravity to isolate the space inside the bottle body from the external space.

[0018] By means of the above technical scheme, the automatic exhaust extraction device of the present application includes a manual ball valve, an automatic exhaust valve, a bottle cap and a bottle body. The automatic exhaust valve and the bottle cap are installed on the top of the bottle body in an upright state. The manual ball valve is connected to the bottle body through the automatic exhaust valve. The automatic exhaust valve includes a valve core. When the bottle body is in an inverted state, the valve core separates the space inside the bottle body from the external space under the action of gravity, and when the bottle body returns to an upright state, the valve core returns to connecting the space inside the bottle body with the external space. It can be seen that during the repeated oscillation process of the automatic exhaust extraction device, when the bottle is upright, the gas inside the bottle can be released due to the connection between the space inside and outside the bottle. When the bottle is inverted, the space inside and outside the bottle is isolated, which can prevent the outflow of the extract in the bottle. No manual operation is required by the operator, which reduces the workload of the staff and the exposure to toxic and harmful gases, thereby completing the solid waste sample extraction operation safely and quickly.

[0025] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0026] See also Figure 1-Figure 4 The utility model provides a technical solution: an automatic exhaust extraction device, comprising a manual ball valve 1, an automatic exhaust valve 2, a bottle cap 3 and a bottle body 4. The automatic exhaust valve 2 and the bottle cap 3 are installed on the top of the bottle body 4 in an upright state, and the manual ball valve 1 is connected to the bottle body 4 through the automatic exhaust valve 2.

[0027] The automatic exhaust valve 2 includes a valve core 5, so that when the bottle body 4 is in an inverted state, the valve core 5 separates the space inside the bottle body from the external space under the action of gravity, and when the bottle body 4 returns to an upright state, the valve core 5 restores the connection between the space inside the bottle body and the external space.

[0028] For example, when the inspector performs the leaching operation, he first manually loads the weighed solid waste into the leaching bottle, adds the leaching agent and covers the bottle cap 3, closes the manual ball valve 1 and shakes the bottle body 4 to mix the solid waste and the leaching liquid evenly, then fixes the automatic exhaust leaching device on the flipping oscillation device, and opens the manual ball valve 1. When the bottle body 4 of the automatic exhaust leaching device is upright, there is a certain gap between the valve core 5 of the automatic exhaust valve 2 and the spherical cover in the vertical direction, the space in the bottle body is connected to the external space, and the gas in the leaching bottle is connected to the outside world to achieve the exhaust effect. When the bottle body 4 of the automatic exhaust leaching device is inverted, there is no gap between the valve core 5 of the automatic exhaust valve 2 and the spherical cover in the vertical direction, and it is tightly sealed with the valve body, separating the space in the bottle body from the external space, and achieving the effect of preventing the liquid in the leaching bottle from flowing out. It can be understood that during the upside-down flipping of the automatic exhaust leaching device, when the bottle body 4 is upright, the gas cylinder is automatically exhausted, and the operator does not need to operate manually, reducing the workload of the staff and exposure to toxic and harmful gases.

[0029] The automatic exhaust extraction device provided in this embodiment includes a manual ball valve, an automatic exhaust valve, a bottle cap and a bottle body. The automatic exhaust valve and the bottle cap are installed on the top of the bottle body in an upright state. The manual ball valve is connected to the bottle body through the automatic exhaust valve. The automatic exhaust valve includes a valve core. When the bottle body is in an inverted state, the valve core separates the space inside the bottle body from the external space under the action of gravity, and when the bottle body returns to an upright state, the valve core resumes the connection between the space inside the bottle body and the external space. It can be seen that during the repeated oscillation process of the automatic exhaust extraction device, when it is upright, the gas inside the bottle can be released due to the connection between the space inside and outside the bottle, and when it is inverted, the space inside and outside the bottle is isolated, which can prevent the outflow of the extract in the bottle. There is no need for manual operation by the operator, which reduces the workload of the staff and the exposure to toxic and harmful gases, thereby completing the solid waste sample extraction operation safely and quickly.

[0030] In some embodiments of the present application, the automatic exhaust valve 2 mentioned in the above embodiment is further introduced.

[0031] Specifically, the automatic exhaust valve 2 may be a hollow structure, such as Figure 2 As shown, the automatic exhaust valve 2 includes two rods and a support column 6, which are respectively a first rod and a second rod. There is a spherical cover between the two rods. The first rod of the automatic exhaust valve 2 is connected to the second rod through the spherical cover. The spherical cover is built with a valve core 5. The first rod is connected to the manual ball valve 1, and the second rod is connected to the bottle body 4.

[0032] Among them, Figure 3 As shown, the support column 6 is arranged in the spherical cover on the side of the second column rod, so that when the bottle body 4 is upright, there is a gap between the valve core 5 and the second column rod under the action of gravity to connect the space in the bottle body with the external space.

[0033] It is understandable that, since the support column 6 supports the valve core 5, the valve core 5 will not be completely in contact with the second column rod under the action of gravity, and the gas in the bottle can be discharged out of the bottle through the gap under the air pressure in the bottle.

[0034] like Figure 4 As shown, there is no supporting structure in the spherical cover and on the side of the first column, so that when the bottle body 4 is inverted, the valve core 5 is completely fitted with the first column under the action of gravity to isolate the space inside the bottle body 4 from the external space.

[0035] It is understandable that, when the bottle body 4 is inverted, there is no supporting structure in the spherical cover and on the side of the first column rod, and the valve core 5 is completely fitted with the first column rod under the action of gravity, and the extract in the bottle will not flow out of the bottle.

[0036] In addition, the shape and structure of the valve core 5 may be further designed.

[0037] Specifically, the curvature of the valve core 5 on the side of the first column can be the same as the curvature of the spherical cover, and the curvature of the valve core 5 on the side of the second column is inconsistent with the curvature of the spherical cover. In this way, when the bottle body 4 is upright, the valve core 5 is under the action of gravity, even if there is no support column 6 to lift the valve core 5, because the shape and structure of the valve core 5 cannot be completely fitted with the second column, the space inside the bottle body 4 can also be connected with the external space. When the bottle body 4 is inverted, the valve core 5 is under the action of gravity, because the shape and structure of the valve core 5 is the same as the curvature of the spherical cover, the valve core 5 is completely fitted with the first column to isolate the space inside the bottle body 4 from the external space.

[0038] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device. In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the presence of other identical elements in the process, method, article or device including the elements.

[0039] The various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The various embodiments can be combined as needed, and the same or similar parts can refer to each other.
