Description

Technical Field

[0001] The utility model belongs to the technical field of core test auxiliary devices, and in particular relates to a structure capable of simulating the core to generate gas. Background Art

[0002] In the process of core research, the core is usually tested. In this process, the analysis gas calculation of the core is involved. This process is carried out in a sealed container (analysis tank), so the experimental container needs to be calibrated before the core test.

[0003] In the prior art, the sealing test of a container is usually carried out by pumping air into the sealed container. After the inflation is completed, the pressure inside the container is observed by the pressure gauge on the container to determine the amount of gas pumped into the container. Because the amount of gas entering the container cannot be known at the pump, the amount of gas can only be calculated theoretically through the pressure change of the container. In this way, it is impossible to determine whether the pressure gauge is faulty, and thus the calibration of the test container cannot be guaranteed. In addition, the use of the structure of the pump will involve adding a pipe mouth and will also face the risk of leakage, which is of poor practicality. Utility Model Content

[0004] The embodiment of the utility model provides a structure capable of simulating gas generation from a core, aiming to solve the problem that existing core testing containers cannot be calibrated.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: to provide a structure that can simulate the gas generated by the core, including:

[0006] The tank body has a receiving cavity with an open top, and the receiving cavity is used to store the effervescent tablet;

[0007] A top cover is arranged at the open opening of the tank body and is detachably connected to the tank body, and a vent is provided on the top cover;

[0008] A water storage box is detachably connected to the top cover and enclosed with the top cover to form a water storage space. The water storage box is used to extend into the accommodating cavity after the top cover is connected to the tank body. A drainage pipe is provided on the water storage box, and a solenoid valve is provided on the drainage pipe.

[0009] The matching controller is used to control the electromagnetic valve to open so as to guide the water in the water storage box into the accommodating cavity.

[0010] In a possible implementation, the top cover is threadedly connected to the tank body.

[0011] In a possible implementation, a circular groove is provided on the top cover, and the water storage box is threadedly connected to the circular groove.

[0012] In a possible implementation, the water storage box is a cylindrical structure.

[0013] In a possible implementation, the top cover is provided with an auxiliary tube penetrating the top cover, the auxiliary tube is detachably connected with a breathable cover, and a breathable and water-blocking film is provided inside the breathable cover.

[0014] In a possible implementation, a supporting leg is provided at the bottom end of the tank body.

[0015] In this implementation, the reaction between the effervescent tablet and water releases carbon dioxide gas, which can more closely simulate the analysis of the core, and the simulation effect is good. The combination of the tank body, the top cover and the water storage box can ensure that the water and the effervescent tablet are separated. At the same time, the controller and the solenoid valve can ensure that the water and the effervescent tablet are mixed after the container to be tested is sealed. This structure can know the amount of gas released in advance, and then can ensure that it is compared with the amount of gas calculated by the change value of the pressure gauge, which can ensure the detection of the pressure gauge on the test container, and then ensure the correction of the test container. It has a simple structure, is easy to manufacture, and has strong practicality. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0020] Please also read Figure 1Now, the structure of the utility model that can simulate the core gas generation is described. The structure that can simulate the core gas generation includes a tank body 10, a top cover 20, a water storage box 30 and a matching controller 40. Among them, the tank body 10 has a receiving chamber 11 with an open top, and the receiving chamber 11 can store effervescent tablets. The top cover 20 is arranged at the open part of the tank body 10, and is detachably connected to the tank body 10, and a vent is provided on the top cover 20. The water storage box 30 is detachably connected to the top cover 20, and is enclosed with the top cover 20 to form a water storage space. After the top cover 20 is connected to the tank body 10, the water storage box 30 can extend into the receiving chamber 11. A drain pipe 31 is provided on the water storage box 30, and a solenoid valve 32 is provided on the drain pipe 31. The matching controller 40 can control the solenoid valve 32 to open, so as to guide the water in the water storage box 30 into the receiving chamber 11.

[0021] The structure that can simulate the gas generation of the core provided in this embodiment is used in the following manner: first, the top cover 20 is disassembled, and then one or more effervescent tablets are placed in the accommodating chamber 11. The specific number can be determined according to the volume of the container to be tested, and the amount of gas that can be released by each effervescent tablet is usually 50 ml. Then, the water storage box 30 filled with water is connected to the top cover 20, and the top cover 20 is connected to the tank body 10. Then, the combination of the tank body 10, the top cover 20, and the water storage box 30 is placed in the container to be tested, and the container to be tested is sealed, and the pressure indication number P1 on the container is recorded. The solenoid valve 32 is opened by the controller 40, so that the water in the water storage space is directly introduced into the accommodating chamber 11, and the effervescent tablet begins to react after encountering water to produce carbon dioxide. After the reaction of each effervescent tablet is completed, until the indication of the pressure gauge no longer changes, the pressure indication number P2 on the container is recorded. By the formula (P1-P2)V=(n1-n2)RT, the change in gas, that is, the amount of gas generated, can be calculated in theory. The number of effervescent tablets placed previously is fixed, and the actual amount of gas produced can be directly obtained. If the two are equal, the pressure gauge is normal and the container can be used normally.

[0022] In this process, the actual amount of gas produced by each effervescent tablet is not absolutely 50ml, so the experimental process can be carried out multiple times. Assuming that the results each time are infinitely close, the pressure gauge is normal.

[0023] In addition, regarding the controller 40, the power supply, control switch and remote control can be guaranteed. The power supply can be set on the top cover 20, and connected before the control switch and the solenoid valve 32 through electrical connection. The staff can control the opening and closing of the control switch through the remote control. This technology is existing technology and will not be repeated here.

[0024] The structure provided in this embodiment can simulate the gas generation of the core. Compared with the prior art, the carbon dioxide gas is released by the reaction of the effervescent tablet and water, which can simulate the analysis of the core more closely, and the simulation effect is good. The combination of the tank body 10, the top cover 20 and the water storage box 30 can ensure that the water and the effervescent tablet are separated. At the same time, the controller 40 and the electromagnetic valve 32 can ensure that the water and the effervescent tablet are mixed after the container to be tested is sealed. This structure can know the amount of gas released in advance, and then can ensure that it is compared with the amount of gas calculated by the change value of the pressure gauge, which can ensure the detection of the pressure gauge on the test container, and then ensure the correction of the test container. It has a simple structure, is easy to manufacture, and has strong practicality.

[0025] In some embodiments, the top cover 20 may be Figure 1 See the structure shown. Figure 1 The top cover 20 is threadedly connected to the tank body 10. This structure can facilitate the disassembly and assembly of the combination of the top cover 20 and the water storage box 30 to ensure that the impurities in the accommodating chamber 11 are cleaned, thereby facilitating the cleaning work inside the accommodating chamber 11. In addition, this connection structure is simple and easy to operate.

[0026] In some embodiments, the top cover 20 may be Figure 1 See the structure shown. Figure 1 A circular groove is provided on the top cover 20, and the water storage box 30 is threadedly connected to the circular groove.

[0027] The circular groove can be arranged at the center of the top cover 20 to ensure that after the water storage box 30 is threadedly connected with the circular groove, the water storage box 30 is located at the center of the accommodating cavity 11. Correspondingly, a plurality of vents can be arranged, each of which is arranged around the outer periphery of the circular groove.

[0028] In addition, this structure can also facilitate the replacement of the water storage box 30 to meet the changes in different water consumption.

[0029] In some embodiments, the water storage box 30 can be used as follows Figure 1 See the structure shown. Figure 1 The water storage box 30 is a cylindrical structure with a simple structure and is easy to manufacture, and can be directly connected to the circular groove.

[0030] In some embodiments, the top cover 20 may be Figure 1 See the structure shown. Figure 1The top cover 20 is provided with an auxiliary tube 21 that passes through the top cover 20, and a vent cover 22 is detachably connected to the auxiliary tube 21, and a vent cover 22 is provided inside the vent cover 22. Through the arrangement of the auxiliary tube 21 and the vent cover 22, it can be ensured that the gas outside the water storage space can enter the water storage space, so as to ensure that the pressure inside the water storage space is consistent with the external pressure, avoid negative pressure in the water storage space, and ensure that water can flow freely into the accommodating chamber 11. In addition, the threaded connection between the vent cover 22 and the auxiliary tube 21 can mainly ensure the disassembly and assembly of the vent cover 22, facilitate the injection of water into the water storage space, and also facilitate the replacement of the vent cover 22.

[0031] In some embodiments, the tank 10 may be formed as follows: Figure 1 See the structure shown. Figure 1 The bottom end of the tank body 10 is provided with a support leg 12. The arrangement of the support leg 12 can ensure the stability of the tank body 10 placed in the container, and the structure is simple, and a three-leg support structure can be adopted.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
