[0055] It is found through research that when determining the risk of releasing flammable gas substances when encountering water, the existing method is to inject water into the reaction bottle through a funnel. During this process, a portion of the air inside the reaction bottle is squeezed, causing the gas inside the reaction bottle to flow. When the flowing gas passes through the gas flow meter, it will generate a certain value, ultimately causing the test result to deviate, which will affect the judgment of the risk of the substance. If the gas flow caused by the injection of water into the bottle is excluded, it may also lead to inaccurate test results for samples with a large initial gas release amount.
[0056] Based on the above research, the water drainage mechanism and the water drainage experiment device are provided, the water drainage mechanism is arranged in the inside of the reaction tank, and the water in the water drainage mechanism is injected into the reaction tank through the water drainage mechanism when the experiment starts. Compared with the prior art of injecting water from the outside of the reaction bottle, the inside of the reaction bottle is injected, the change of the gas pressure in the reaction bottle is reduced, the change of the gas flow is indirectly reduced, and the detection result is closer to the true value.
[0057] The defects of the above scheme are the results of the inventors after practice and careful research, therefore, the discovery process of the above problems and the solutions proposed by the present disclosure for the above problems should be the contributions of the inventors to the present disclosure in the process of the present disclosure.
[0058] It should be noted that similar reference numerals and letters represent similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined and explained in subsequent drawings.
[0059] Some embodiments of the present application will be described in detail below with reference to the accompanying drawings. In the case of no conflict, the embodiments described below and the features in the embodiments can be combined with each other.
[0060] In some embodiments, as shown in Figure 1 Before the experiment starts, the reaction material is placed in the inside of the reaction tank 1, and then the sealing cover 10 is covered on the top end of the reaction tank 1 for sealing. At this time, the operator manually rotates the knob 20, the knob 20 is connected with the bearing of the reaction tank 1, the rotation of the knob 20 drives the moving part 22 connected with the rotating shaft 21 to move, until the moving part 22 no longer blocks the bottom hollow water storage tank 12, at this time, the water pre-injected in the water storage tank 12 flows into the reaction tank 1 and mixes with the reaction material.
[0061] In some embodiments, as shown in Figure 1 When the water in the water storage tank 12 enters the reaction tank 1 and contacts the reaction material, the driver 33 is started at this time, the output end of the driver 33 drives the magnetic stirring part 32 to rotate. Since the inside of the horizontal part 31a is provided with a magnetic part, with the rotation of the magnetic stirring part 32, the horizontal part 31a drives the vertical part 31b to rotate in the inside of the reaction tank 1 to stir the water and the reaction material to promote the contact. (The material of the horizontal part 31a is usually composed of a chemical stable shell, preferably ceramic, and the material of the magnetic part includes but is not limited to a neodymium magnet)
[0062] In some embodiments, as shown in Figure 2As shown, when the knob 20 rotates, the rotating shaft 21 fixedly connected with the knob 20 rotates, the rotating shaft 21 is engaged with the thread groove on the moving piece 22 through the thread on the outer wall of the rotating shaft 21, and then the moving piece 22 is driven to move, since one end of the guide rod 24 is connected with the inner wall of the reaction tank 1 and the other end is inserted into the guide groove 25, therefore the moving piece 22 can only move along the axial direction of the guide rod 24, that is, horizontally move below the water storage tank 12.
[0063] As preferred, in order to make the water in the water storage tank 12 completely flow out of the water storage tank 12 after the moving piece 22 moves, the angle between the upper end surface of the moving piece 22 and the inner bottom surface of the reaction tank 1 is 5-10°, preferably 5°, in order to avoid water leakage in the water storage tank 12, the angle between the lower end surface of the water storage tank 12 and the inner bottom surface of the reaction tank 1 is consistent with the angle between the upper end surface of the moving piece 22 and the inner bottom surface of the reaction tank 1, and at the same time, the inclination angles of the guide rod 24, the rotating shaft 21 and other components are synchronously adjusted with the inclination angle of the moving piece 22 to ensure the smooth movement of the moving piece 22.
[0064] In some embodiments, as Figure 3 As shown, after the reactants and the water in the water storage tank 12 are mixed, the generated gas is guided into the gas flow meter through the gas guide pipe 11 for detection (the specifications of the gas flow meter and the connection mode of the gas guide pipe 11 and the gas flow meter are prior art, and details are not described herein).
[0065] In the description of the embodiments of the present application, unless otherwise explicitly specified and limited, the terms "mounting", "connecting", "connecting" should be understood in a broad sense, for example, it can be fixedly connected, or it can be detachably connected, or integrally connected, it can be mechanically connected, or it can be electrically connected, it can be directly connected, or indirectly connected through an intermediate medium, or it can be the communication between two elements. For ordinary skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0066] In the description of the present application, it should be explained that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, therefore it cannot be understood as a limitation on the present application. In addition, terms such as "first", "second" and other numerical terms are used herein, unless otherwise explicitly indicated herein. Therefore, the first element, component, area, layer or section discussed above can be referred to as the second element, component, area, layer or section without departing from the teaching of the example embodiments.
[0067] Spatially relative terms, such as "inner," "outer," "beneath," "below," "lower," "above," "upper," and the like, can be used herein for ease of description to describe one element or feature's relationship to another element(s) or feature(s) as illustrated in the figures. Spatially relative terms can be intended to encompass different orientations of the device in use or operation in addition to the orientation depicted in the figures. For example, if the device in the figures is turned over, elements described as "below" or "beneath" other elements or features would then be oriented "above" the other elements or features. Thus, the example term "below" can encompass both an orientation of above and below. The device can be otherwise oriented (rotated 90 degrees or at other orientations) and the spatially relative descriptors used herein interpreted accordingly.
[0068] In the above discussion, unless otherwise stated, the terms "about," "approximately," "substantially" and the like mean a variation of + / - 10% when used to describe a numerical value.
[0069] With the above ideal embodiments according to the present application as the inspiration, through the above description, relevant staff can definitely make various changes and modifications without deviating from the technical thought of the present application. The technical scope of the present application is not limited to the content in the specification, and must be determined according to the scope of claims.
