[0002] The calorific value of coal is an important index for judging the quality of coal and is also an essential pricing index in coal trading. The calorific value of coal is generally measured using a calorimeter.

[0003] The oxygen bomb is the main component of the calorimeter. During the test, a certain amount of sample is placed in the oxygen bomb filled with excessive oxygen and burned. The released heat causes the temperature of the entire calorimetric system (including the oxygen bomb, the inner cylinder, the water in the inner cylinder, the stirrer, and the thermometer) to rise. Then, according to the heat capacity of the calorimeter, the temperature rise of the calorimetric system, and the mass of the sample, the calorific value of the sample is calculated.

[0004] The existing oxygen bombs usually use a threaded switch cover. Not only is it laborious to open and tighten during use, but the threads will also wear out after long-term use, which may lead to accidents in severe cases. Content of the Utility Model

[0042] To more clearly illustrate the technical solutions in the embodiments of the present invention or the prior art, the following will describe the specific embodiments of the present invention with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, further technical solutions can be understood. Among some of the figures, components with the same structure or function are only schematically shown for one of them, or only one of them is marked. In this article, "one" not only means "only this one", but also can mean "more than one" situation, and "several" includes "two" and "more than two".

[0043] In this article, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0044] In addition, in the description of this application, the terms "first", "second", etc. are only used for distinguishing descriptions and cannot be understood as indicating or implying relative importance.

[0045] Referring to Figures 1 to 5 , the first embodiment of the present invention provides a quick-opening and closing oxygen bomb, including:

[0046] A bomb body 1, having a use space 2 inside the bomb body 1, and an opening 3 at the top of the bomb body 1, and the opening 3 is communicated with the use space 2;

[0047] A bomb cover 4, detachably arranged on the bomb body 1, and the bomb cover 4 is used to open or close the opening 3;

[0048] There are several clamping blocks 5, arranged on the bomb body 1, and a clamping space is formed between several clamping blocks 5, and the clamping space is used to clamp the bomb cover 4.

[0049] In this embodiment, the oxygen bomb is composed of a bomb body 1 and a bomb cover 4. When the oxygen bomb is in use, coal is usually placed in the use space 2, and then the bomb cover 4 is covered on the monomer. Then, the bomb cover 4 is placed in the clamping space of the clamping block 5 to tightly clamp the bomb cover 4 to prevent the bomb cover 4 from detaching from the bomb body 1. Then, oxygen is filled into the use space 2 to ensure that the coal inside the use space 2 can burn completely, and then various data such as the calorific value of the coal inside the use space 2 are confirmed. By using the clamping block 5 to clamp the bomb cover 4 on the bomb body 1, it can not only ensure that the bomb cover 4 can be covered more quickly when the oxygen bomb is in use, but also compared with the traditional thread form, the clamping block 5 is not easily worn, ensuring the safety of the oxygen bomb during use. Moreover, even if the form of the clamping block 5 is worn, it will only reduce the sealing performance between the bomb cover 4 and the bomb body 1, and will not cause more serious consequences, further improving the safety.

[0050] As a further technical solution, the clamping block 5 has a clamping groove 6, and further includes:

[0051] Protrusions 7, several of them, are circumferentially spaced on the bomb cover 4, and the protrusions 7 cooperate with the clamping groove 6.

[0052] In this embodiment, the protrusions 7 are located on the bomb body 1. When the bomb cover 4 needs to be installed, first place the bomb cover 4 at the opening 3 of the bomb body 1. After placing it in place, by rotating the bomb cover 4, the protrusions 7 on the bomb cover 4 will enter the clamping groove 6, thereby ensuring that the bomb cover 4 can be tightly clamped by the protrusions 7, preventing the bomb cover 4 from detaching and at the same time improving the installation speed of the bomb cover 4, ensuring the use speed of the oxygen bomb. Through the cooperation of the protrusions 7 and the clamping groove 6, the wear resistance of the equipment is further improved, ensuring the overall safety of the equipment.

[0053] As a further technical solution, it further includes:

[0054] A limiting block 8 is arranged in the clamping groove 6, and the limiting block 8 is used to limit the clamping position of the bomb cover 4.

[0055] In this embodiment, the limiting block 8 is located at one end of the clamping groove 6. When the bomb cover 4 is installed on the bomb body 1, through the rotation of the bomb cover 4 itself, the protrusions 7 will enter the clamping groove 6 to make the connection between the bomb cover 4 and the bomb body 1 tighter. When the connection is the tightest, the protrusions 7 are blocked by the limiting block 8, and at this time the bomb cover 4 can no longer rotate, indicating that the bomb cover 4 has rotated to the best position and the rotation of the bomb cover 4 can be stopped. By using the relief block, the installation steps are simpler and more convenient, and it can also prevent the connection from being loose due to excessive rotation, causing potential safety hazards. When removing the bomb cover 4, the bomb cover 4 needs to be rotated in the reverse direction to ensure that the protrusions 7 leave the clamping groove 6. When the protrusions 7 completely leave the clamping groove 6, the bomb cover 4 can be completely removed.

[0056] As a further technical solution, the projectile body 1 is provided with a sealing groove 9, and the sealing groove 9 is located below the clamping groove 6. It further includes:

[0057] A gasket 10, which is arranged on the projectile cover 4. After the projectile cover 4 is installed, the gasket 10 cooperates with the sealing groove 9 for sealing.

[0058] In this embodiment, the gasket 10 is used to seal the projectile cover 4 and the projectile body 1. When the projectile cover 4 is installed on the projectile body 1, the cooperation between the gasket 10 and the sealing groove 9 can ensure the sealing effect between the projectile cover 4 and the projectile body 1. The gasket 10 is made of high-temperature resistant material, which can not only ensure good sealing performance but also withstand the high temperature inside the processing space, preventing the sealing failure from affecting the detection effect.

[0059] As a further technical solution, it further includes:

[0060] An oxygen warhead 11, which is arranged on the projectile cover 4. The oxygen warhead 11 is provided with a vent hole 12, and the vent hole 12 penetrates through the oxygen warhead 11 and communicates with the use space 2;

[0061] A valve 13, which is arranged on the oxygen warhead 11.

[0062] In this embodiment, during the experimental test, it is necessary to fill the inside of the processing space with sufficient oxygen. The settings of the oxygen warhead 11 and the valve 13 ensure that oxygen can be added to the processing space faster without leakage, and the valve 13 can ensure that the amount of oxygen added can be controlled at any time, improving the control accuracy.

[0063] As a further technical solution, it further includes:

[0064] A support frame 14, which is arranged on the projectile cover 4;

[0065] A crucible 15, which is arranged on the support frame 14; the crucible 15 is used to place the coal sample to be detected;

[0066] An ignition wire 16, which is arranged on the support frame 14.

[0067] In this embodiment, the crucible 15, the ignition wire 16, etc. are all set to adapt to the detection experiment. Through the connected support frame 14, the coal to be detected can be placed inside the crucible 15 before the projectile cover 4 is installed. After the installation is completed and the oxygen is added, the temperature can be raised to a sufficient temperature by the ignition wire to make the coal burn fully, making the detection experiment more convenient and shortening the preparation time required for the experiment.

[0068] As a further technical solution, it further includes:

[0069] The fire baffle 17 is arranged on the support frame 14. The fire baffle 17 is located above the support frame 14, and the fire baffle 17 is used to block the flame in the crucible 15.

[0070] In this embodiment, during the experiment, the coal burns in an environment with sufficient oxygen, usually generating a relatively large flame. The flame support burns the bullet cover 4, the valve 13, etc. The fire baffle 17 is arranged in the middle of them to prevent the flame generated by combustion from directly burning the bullet cover 4 or the valve 13, thereby improving the service life of the device.

[0071] As a further technical solution, it further includes:

[0072] The guiding ring 18 is arranged on the bullet cover 4, and the guiding ring 18 is used to guide the bullet cover 4 into the bullet body 1.

[0073] In this embodiment, the guiding ring 18 is arranged on the bullet cover 4. When the bullet cover 4 needs to be installed on the bullet body 1, the frustum-shaped guiding ring 18 will guide the bullet cover 4 to be installed on the bullet body 1 faster and better, improving the installation speed and ensuring the installation quality at the same time.

[0074] As a further technical solution, the bullet cover 4 further has a plurality of locking holes 19, the bullet body 1 has a plurality of locking holes 20, and the positions of the locking holes 20 and the locking holes 19 correspond one by one. It further includes: a locking rod 21 is slidably arranged in the locking hole 19, and after the locking rod 21 slides, it enters or exits the locking hole 20; both ends of a first elastic member 22 are respectively arranged on the locking rod 21 and the bullet cover 4, and the first elastic member 22 is used to provide a force for the locking rod 21 to move away from the locking hole 20. The bullet cover 4 further has a pressure relief hole 23, and it further includes: a pressure relief valve 24 is arranged on the pressure relief hole 23, and the pressure relief valve 24 is used to control the opening or closing of the pressure relief hole 23.

[0075] In this embodiment, when the bullet body 1 is sealed by the bullet cover 4, it is necessary to introduce oxygen to ensure sufficient oxygen in the use space 2. At this time, the pressure inside the use space 2 is very high, causing the locking rod 21 to slide out of the locking hole 19 and enter the locking hole 20. At this time, the bullet cover 4 cannot slide anymore, further improving the safety performance of the bullet cover 4. When it needs to be opened, the pressure relief valve 24 is opened. At this time, the locking rod 21 leaves the locking hole 20 under the action of the elastic member, and then the bullet cover 4 can slide, ensuring that the bullet cover 4 can be opened normally.

[0076] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and all of them should be covered by the scope of the claims of the present invention.
