[0038] Example

[0039] like Figures 1-6 As shown, the present invention provides a molding die for pressing straw carbon powder into porous biochar blocks, comprising:

[0040] The lower mold includes a mold core 1, at least two side pressure blocks 4, a middle mold sleeve 2, and an outer mold sleeve 3. The two side pressure blocks 4 are disposed opposite to each other outside the mold core 1. The middle mold sleeve 2 is sleeved outside the mold core 1 and the two side pressure blocks 4. The outer mold sleeve 3 is sleeved outside the middle mold sleeve 2.

[0041] The mold core 1 is provided with a forming cavity 13, the bottom of the forming cavity 13 is provided with a core rod 11, and the side wall of the mold core 1 is provided with a plurality of through holes 12.

[0042] One side of the side pressure block 4 is provided with a side core rod 41 adapted to several through holes 12, and the other side of the side pressure block 4 is provided with an inclined top block 42.

[0043] The inner wall of the middle mold sleeve 2 is provided with a movable cavity 22 that is adapted to the side pressure block 4, and the side wall of the middle mold sleeve 2 is provided with a movable groove 23 that is adapted to the inclined top block 42. The inclined top block 42 extends out of the movable groove 23. It should be noted that the width of the inner cavity 21 inside the middle mold sleeve 2 is greater than the width of the movable cavity 22, so it can be left to adapt to the top corner of the mold core 1 for fixing.

[0044] The inner wall of the outer mold sleeve 3 is provided with an inclined groove that matches the inclined top block 42, and the outer mold sleeve 3 is higher than the middle mold sleeve 2;

[0045] An upper mold 6 is provided above the lower mold, and the bottom surface of the upper mold 6 is provided with a protrusion that is adapted to the forming cavity 13.

[0046] The brief working principle of the technical scheme is that the carbon powder prepared from the straw is put into the forming cavity 13, then the upper die 6 is pressed downward to press the carbon powder into a biochar block, and the core rod 11 and the side core rod 41 are used to form the air permeable holes on the biochar block during the forming process. The core rod 11 is fixed in the forming cavity 13 of the die core 1, and the side die core 41 is movable. Normally, the outer die sleeve 3 is located at the upper portion of the middle die sleeve 2, and the inclined groove on the inner wall of the outer die sleeve 3 is located above the inclined pressing block 42. During the pressing process of the upper die 6, the outer die sleeve 3 is pressed to move downward, the inclined groove is abutted against the inclined pressing block 42, and then the side pressing block 4 is pushed inward, the side pressing block 4 drives the side core rod 41 to move forward, the side core rod 41 is extended into the forming cavity 13 to form the lateral air permeable holes on the biochar block, and then the upper die 6 is retracted, the outer die sleeve 3 is moved upward, and the side pressing plate 4 is also retracted. At this time, the biochar block has been formed and can be demolded (the related structure for demolding by high-pressure gas is not shown in the figure).

[0047] The core rod 11 and the side core rod 41 are used to increase the air permeable holes on the formed biochar block, so that the contact area between the biochar block and air is increased, and then the combustion effect of the biochar block is improved, and the biochar block can be fully combusted.

[0048] In an embodiment, the side pressing block 4 has four, and the four side pressing blocks 4 are arranged on four sides of the die core 1 respectively. Each two side pressing blocks 4 form a group, and the positions of the side core rods 41 of each group of side pressing blocks 4 correspond to each other, and the side core rods 41 of different groups of side pressing blocks 4 are staggered.

[0049] The extra side pressing blocks 4 can increase more air permeable holes on the biochar block, and the side core rods 41 at different angles will not interfere with each other. In addition, the air permeable holes formed on the biochar block will not be too close, so as to affect the structural strength of the biochar block and avoid the biochar block from being easily broken.

[0050] In an embodiment, a spring is sleeved on each side core rod 41, and the spring is constrained between the side pressing block 4 and the die core 1.

[0051] The spring can reset the side pressing block 4 without the pressure of the outer die sleeve 3, so as to facilitate the demolding of the formed biochar block.

[0052] In an embodiment, the top of the outer wall of the die core 1 is provided with an annular step 14, and the inner wall of the middle die sleeve 3 is provided with a step hole matched with the step 14.

[0053] The step 14 and the step groove are used to position the die core 1 and the middle die sleeve 2, so as to avoid the die core 1 from being separated from the middle die sleeve 2.

[0054] In an embodiment, the bottom surface of the outer die sleeve 3 is provided with a guide hole at each corner, and an elastic guide column 5 is arranged in the guide hole.

[0055] The elastic guide column 5 is used to reset the outer sleeve 3.

[0056] In an embodiment, the height of the outer sleeve 3 is less than or equal to the height of the mold core 1.

[0057] The bottom surface of the outer sleeve 3 is prevented from contacting the workbench, thereby affecting the pushing side pressing block 4.

[0058] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present application, and are not limited thereto; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that: it can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement for part or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application.
