[0002] Coal is my country's primary energy source, and the efficient development of coal resources is crucial for ensuring people's livelihoods and social stability. Researching coal mining technology to make it safer and more efficient is extremely important. Currently, most laboratories and universities in my country are conducting coal-related scientific research. In the process of experimental research, it is inevitable to pre-treat coal samples, the most common method being crushing the coal and pressing it into briquettes of specific shapes and sizes to meet the experimental research requirements.

[0003] For example, Chinese patent CN218937930U, entitled "A Briquette Pressing Mold for Testing the Mechanical Parameters of Crushed Soft Coal Rock," addresses cylindrical briquette molds. Through a structure including a pressure-bearing base, a mold fixing groove, a briquette sample preparation mold, a support, and a pressure loading device mounted on the support, it achieves control and preparation of cylindrical briquette sample dimensions. Chinese patent CN205685793U discloses a variable-size mold for cylindrical briquettes. Furthermore, Chinese patent CN206223513U also solves the problem of pressing ordinary cylindrical briquettes.

A fastening screw 14 is connected to the end face of the wiring unit perpendicular to the wiring structure dividing line 13. Multiple wiring units are connected together by the fastening screw 14 to form a detachable wiring structure 2.

[0034] like Figure 4 As shown, the briquette pressing mold also includes a pull rod device for lifting the detachable wiring structure 2. The pull rod device consists of a pull ring 18 at the top connected to a pull rod 17 at the bottom. The bottom end of the pull rod 17 is tapped with a threaded section 19, which is connected to the screw hole 12 on the detachable wiring structure 2.

[0035] like Figure 5 As shown, the briquette pressing mold also includes a drilling device that works with the detachable wiring structure 2 to drill holes in the briquette. The drilling device consists of a handle 16 at the top connected to a drill rod 15 at the bottom. The size of the drill rod 15 is adapted to the wiring opening 11 on the detachable wiring structure 2.

[0036] like Figure 6 As shown, the mold body includes a cylindrical mold 3 and a detachable pressure-bearing base 6 assembled together. The cylindrical mold 3 has a square filling cavity 4 inside. The size of the filling cavity 4 is larger than the size of the detachable wiring structure 2 so that it can be pressed into the mold body. The upper end surface of the detachable pressure-bearing base 6 is provided with a pressure-bearing base protrusion 5 that can be tightly fitted into the filling cavity 4.

[0037] The cylindrical mold 3 has eight columnar mold screw holes 20 evenly opened along the circumference on its bottom surface. The detachable pressure base 6 has a detachable pressure base screw hole 21 corresponding to each columnar mold screw hole 20 on its upper surface.

The outer visual reserved opening 8 and the inner visual reserved opening 25 are the same size and are in the same position.

[0040] Work process:

[0041] 1) After preparing the raw materials for briquette pressing, assemble the cylindrical mold 3 with the pre-reserved rectangular cavity inside and the detachable pressure base 6. Secure the two parts together with screws through the pre-reserved screw holes. Then, the pre-prepared raw materials can be loaded into the loading cavity 4. Depending on the needs, it can be loaded all at once or in stages.

[0042] 2) Here is a case where the material is loaded in two stages as required by the experiment: First, the material is loaded into the loading cavity 4 by 3cm. Then, the wiring units of the detachable wiring structure 2 are assembled together according to the wiring device dividing line 13, and the fastening screws 14 are tightened. Then, the threaded section 19 at the end of the pull rod 17 is rotated into the screw hole 12. At this time, the detachable wiring structure 2 is lifted by the pull ring 18, and the material is pressed down slightly from the top of the loading cavity 4 to compact the material loaded in the first stage. This step is to ensure that the data cable is in the right position after the briquette is pressed into shape.

[0043] 3) The remaining raw materials are loaded for the second time. The assembled detachable wiring structure 2 is placed on top of the loading cavity 4 and pressed down by about 1cm to 2cm. The drill rod 15 is inserted into the wiring port 11 reserved in the detachable wiring structure 2 until it contacts the first layer of raw materials (because the first loading was compacted, the contact with the layer can be clearly felt when drilling).

[0044] 4) After drilling holes in sequence, the prepared data cables can be placed into the holes one by one. The pressure head 1 has a large slotted design. If the data cable is too long, the excessive part can be led out from the slot. At this time, the pressure head 1 can be placed on the detachable wiring structure 2 and the whole thing can be put into the press for briquetting.

[0045] 5) While waiting for the briquette to be pressed, the inner buffer layer 24 can be placed inside the outer pressure layer 22. Note that the reserved visualization holes of the two layers should be aligned. After the briquette is pressed, the detachable pressure base 6 can be removed and replaced with the double-layer demolding device 7 to continue demolding. Due to the buffer layer, the briquette will not be damaged after demolding. After the briquette is demolded, the fastening screws 14 of the detachable wiring structure 2 can be removed. Then, each part of the device can be removed in turn. At this time, the internally wired pressed briquette can be obtained.

[0046] This invention achieves a damage-free demolding process by designing a double-layer demolding device, and enables the operation of pre-embedding various data lines when pressing square coal samples through the cooperation of a drilling device and a detachable wiring device. The size data of the pressed coal briquettes is accurate, providing reliable samples for subsequent experiments.
