[0004] According to common sense, the thinner the object is, the larger the heating area is, which is more conducive to the evaporation of water and the more thorough the burning of the coal sample. Currently, the crucibles on the market are basically made after the object is flattened so that its mass per square centimeter is close to the national standard value, otherwise the volume of the crucible must be increased, which indirectly leads to the increase of the volume of the entire instrument.

[0005] The crucibles currently on the market have the following problems:

[0014] Wherein, the through holes are circular through holes, the diameters of the plurality of circular through holes are equal, and the plane formed by the centers of the plurality of circular through holes is perpendicular to the axis of rotation of the lower cone.

[0015] Wherein, the diameter of the circular through hole is one quarter to one half of the height of the cone.

[0016] Among them, it also includes a glaze layer coated on the surface of the water-cement detection cavity.

[0017] Wherein, the side wall thickness of the water-cement detection cavity gradually decreases from bottom to top.

[0018] Wherein, the support portion, the water-cement detection cavity and the cone are an integrated structure.

[0019] In addition, an embodiment of the present application further provides a water-ash detection device, comprising the water-ash crucible and a turntable as described above, wherein the cone of the water-ash crucible is engaged with the limiting hole of the turntable.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Please refer to Figure 1-Figure 4 , Figure 1 A schematic cross-sectional view of an embodiment of a water-lime crucible provided by the utility model; Figure 2 A three-dimensional structural schematic diagram of an embodiment of a water-lime crucible provided by the utility model; Figure 3 It is a structural schematic diagram of a water-ash crucible in the prior art; Figure 4 The present invention is a schematic structural diagram of an embodiment of a water-cement detection device provided by the utility model.

[0030] In a specific embodiment, the water-cement crucible includes a cone 3 that contracts laterally from top to bottom, a support portion 10 arranged on the outer side of the top of the cone 3, and a water-cement detection cavity 2 arranged on the top of the cone 3. The cone 3 is a cone with a rotating structure, and the water-cement detection cavity 2 is a water-cement detection cavity 2 with a rotating structure. The side outer wall of the water-cement detection cavity 2 is flush with the outer wall of the support portion 10.

[0031] By changing the structure in which the existing cavity for holding the object to be tested is retracted relative to the support portion 10, the bottom outer wall of the water-cement detection cavity 2 is flush with the outer wall of the support portion 10. Without changing the lateral dimensions of the overall device and without affecting the existing test device, the water-cement detection cavity 2 is expanded outward to the outer wall of the support portion 10. While the thickness of the side wall of the water-cement detection cavity remains unchanged, the area inside for placing the sample is increased, thereby improving the test efficiency.

[0032] In the present application, the existing independent support part and water-cement detection cavity structure are converted into an integrated structure, so that the support part relative to the side structure of the water-cement detection cavity is changed into the bottom structure in the present application. When the relative position of the support part remains unchanged, the lateral dimension of the water-cement detection cavity is expanded outward, and the actual area carrying the sample is increased. When the weight of the sample remains unchanged, the weight of the sample per unit area is reduced, the heating efficiency is higher, and the detection efficiency is higher.

[0033] In order to reduce the overall weight and improve the convenience of heating, etc., in one embodiment, the cone is a cone with a cavity.

[0034] The size, shape, number, etc. of the cavity are not limited in this application.

[0035] In order to further improve the heating efficiency and reduce the overall weight, improve the heat dissipation efficiency and thus improve the detection efficiency, in one embodiment, the water-ash crucible 1 further includes at least three through holes arranged on the side wall of the cone 3 and connected to the cavity.

[0036] This application does not limit the number, size, and position of the through holes.

[0037] The through hole is in a circular shape, a regular polygonal shape, or other shapes.

[0038] Preferably, the through holes are circular through holes, the diameters of the plurality of circular through holes are equal, and the plane formed by the centers of the plurality of circular through holes is perpendicular to the axis of rotation of the lower cone 3 .

[0039] Preferably, the diameter of the circular through hole is one quarter to one half of the height of the cone.

[0040] In order to improve the efficiency of the test and to facilitate the cleaning of the crucible, in one embodiment, the water-lime crucible 1 further includes a glaze layer coated on the surface of the water-lime detection cavity 2 .

[0041] The present application does not limit the type and thickness of the glaze layer, including but not limited to the glaze layer, and other functional layers that are easy to clean may also be used.

[0042] Since the sample is tested through the water-cement testing cavity in the present application, the lighter the weight, the lower the control difficulty. At the same time, when the material remains unchanged, the thickness is reduced, which can increase the heat dissipation efficiency, increase the temperature drop rate of the sample and the equipment, and improve the sample detection efficiency.

[0043] In one embodiment, the thickness of the side wall of the water-cement detection cavity gradually decreases from bottom to top.

[0044] The thickness of the side wall of the water-cement detection cavity 2 gradually decreases from bottom to top, so that the weight is reduced. While meeting the overall structural strength and improving the sample detection efficiency, the material usage cost can also be reduced.

[0045] The support portion 10, the water-cement detection cavity 2, and the cone 3 described in the present application are separate entities. In order to reduce the difficulty of connection, in one embodiment, the support portion 10, the water-cement detection cavity 2, and the cone 3 are an integrated structure.

[0046] In one embodiment, the water-cement crucible 1 includes a water-cement detection cavity 2 for holding the object to be tested at the top and a cone 3 in a conical shape at the bottom. The upper water-cement detection cavity 2 is a rotating body structure with an open top; the lower cone 3 is an inverted cone rotating body, which is constructed as a cavity structure; at least three circular holes 4 are opened on the side wall of the rotating body.

[0047] The specific implementation process is as follows:

[0048] The water-ash crucible 1 is placed on the turntable 5, the cone 3 is stuck in the limiting hole 6 of the turntable 5 to prevent the water-ash crucible 1 from horizontal displacement, the coal sample is directly placed in the upper cavity, and then the experiment is started.

[0049] By comparing the dimensions of the prior art, while ensuring that the outer dimensions remain unchanged, in one embodiment, the crucible diameter of the present application (diameter 3.6 cm, bottom area 10.17 cm 2 , about 0.098g per square centimeter) is larger than the crucible currently on the market (3.1cm in diameter, 7.54cm in bottom area). 2 , the mass per square centimeter is about 0.13g), which makes the object to be tested spread thinner in the crucible, which is more conducive to improving the experimental efficiency.

[0050] The above device has the following advantages:

[0051] The object to be tested is spread thinner, the test efficiency is high; the structure is simple; and it meets the national standard requirements for coal and coke.

[0052] In addition, an embodiment of the present application further provides a water-ash detection device, comprising the water-ash crucible and a turntable as described above, wherein the cone of the water-ash crucible is engaged with the limiting hole of the turntable.

[0053] Since the water-lime detection device includes the water-lime crucible as described above, it has the same beneficial effects, and this application will not elaborate on this.

[0054] In summary, the water-ash detection device and the water-ash crucible provided by the embodiments of the utility model change the structure in which the existing cavity for holding the object to be tested is retracted relative to the supporting portion into a structure in which the bottom outer wall of the water-ash detection cavity is flush with the outer wall of the supporting portion. The water-ash detection cavity is expanded outward to the outer wall of the supporting portion without changing the lateral dimensions of the overall device and without affecting the existing testing device. While the thickness of the side wall of the water-ash detection cavity remains unchanged, the area inside for placing samples is increased, thereby improving the testing efficiency.

[0055] The water-ash detection device and the water-ash crucible provided by the utility model are introduced in detail above. This article uses specific examples to illustrate the principle and implementation method of the utility model. The description of the above embodiment is only used to help understand the method and core idea of ​​the utility model. It should be pointed out that for ordinary technicians in this technical field, without departing from the principle of the utility model, the utility model can also be improved and modified, and these improvements and modifications also fall within the scope of protection of the claims of the utility model.
