[0029] The exemplary embodiments of the utility model will be described in more detail below with reference to the drawings. Although the exemplary embodiments of the utility model are shown in the drawings, it should be understood that the utility model can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the utility model and to convey the scope of the utility model to those skilled in the art.

[0030] Firstly, referring to Figs. 1 to 3 This utility model discloses a biomass molding die, including a die body module 1 and a pressing block 2. The die body module 1 has a compression channel 11. The pressing block 2 is movably connected to the die body module 1 and has a compression surface 21. The compression surface 21 can extend into the compression channel 11 along a first direction; wherein, the first direction intersects with the extension direction of the compression channel 11.

[0031] This biomass molding die is used in a briquetting equipment. The briquetting equipment includes a die holder, and the die main module 1 is detachably connected to the die holder. The die main module 1 can be an integral structure or a split structure. The overall shape of the die main module 1 can be ring-shaped, square, arc-shaped, U-shaped, etc. The die main module 1 has multiple compression channels 11, which extend through the die main module 1 along their extension direction. The extension direction of the compression channels 11 can be referred to... Fig. 3 The direction indicated by arrow C. The cross-sectional shape of the compression channel 11 can be circular, square, trapezoidal, other quadrilaterals, or other irregular shapes. The preferred cross-sectional shape of the compression channel 11 is square. The cross-section of the compression channel 11 is also the section perpendicular to its extending direction. The compression surface 21 is usually the bottom surface of the pressure block 2, but it can also be the top surface of the pressure block 2. The shape of the compression surface 21 can be circular, rectangular, square, trapezoidal, etc.

[0032] For a single compression channel 11, the number of corresponding pressure blocks 2 can be one or more. When there are multiple pressure blocks 2 corresponding to a single compression channel 11, the multiple pressure blocks 2 can be located on the upper and lower sides of the compression channel 11 respectively, or all of the pressure blocks 2 can be located on the upper side of the compression channel 11 and arranged along the extending direction of the compression channel 11. Preferably, for a single compression channel 11, the number of corresponding pressure blocks 2 is one, and this pressure block 2 is located on the upper side of the compression channel 11.

[0033] The preferred first direction is the height direction of the mold body module 1. The height direction of the mold body module 1 can be referenced. Fig. 2 The direction indicated by arrow A is perpendicular to the extension direction of the compression channel 11. The pressure block 2 is movably connected to the mold body module 1, specifically meaning that the pressure block 2 can be raised and lowered along the first direction while connected to the mold body module 1. Moving the pressure block 2 adjusts the vertical position of the compression surface 21 along the first direction, thereby adjusting the insertion depth of the compression surface 21 into the compression channel 11. After the compression surface 21 extends into the compression channel 11, during the biomass raw material briquetting process, the compression surface 21 will contact the biomass raw material to compress it.

[0034] When the biomass material to be compressed changes and the compression effect and the compactness of the finished product required by the biomass material to be compressed are different from the compression effect and the compactness of the finished product of the biomass material to be compressed before, the friction between the biomass material and the inner wall of the compression channel 11 during compression can be adjusted by adjusting the extension depth of the compression surface 21 into the compression channel 11, so that the compression effect and the compactness of the finished product of the biomass material can be changed, so that the compression effect and the compactness of the finished product of the biomass forming die can be changed. For example, increasing the extension depth of the compression surface 21 into the compression channel 11 can increase the friction between the biomass material and the inner wall of the compression channel 11 during compression, so that the compression effect and the compactness of the finished product of the biomass material can be increased. Reducing the extension depth of the compression surface 21 into the compression channel 11 can reduce the friction between the biomass material and the inner wall of the compression channel 11 during compression, so that the compression effect and the compactness of the finished product of the biomass material can be reduced.

[0035] In the related art, the die in the biomass briquetting machine is usually an integrated die, and the compression effect and the compactness of the finished product of the die are fixed, and the versatility is poor. In order to meet the different requirements of different types of biomass materials on the compression effect and the compactness of the finished product, the biomass briquetting machine needs to be configured with multiple specifications of the entire die, and the die investment cost is high. When the biomass material to be compressed changes and the compression effect and the compactness of the finished product required by the biomass material to be compressed are different from the compression effect and the compactness of the finished product of the biomass material to be compressed before, the entire die needs to be replaced to meet the current requirements of the biomass material on the compression effect and the compactness of the finished product, and the operation is complex and inefficient.

[0036] In the embodiment of the utility model, by adjusting the position of the briquetting 2, the extension depth of the compression surface 21 into the compression channel 11 can be adjusted. After the extension depth of the compression surface 21 into the compression channel 11 changes, the friction between the biomass material and the inner wall of the compression channel 11 during compression will change. The change of the friction will affect the compression effect and the compactness of the finished product of the biomass material. Therefore, by adjusting the extension depth of the compression surface 21 into the compression channel 11, the compression effect and the compactness of the finished product of the biomass material can be changed to meet the different requirements of different types of biomass materials on the compression effect and the compactness of the finished product, and the versatility of the biomass forming die can be enhanced. In addition, the compression effect and the compactness of the finished product of the biomass forming die can be changed by only adjusting the position of the briquetting 2, without replacing the entire die, so the operation is simple, and multiple specifications of the entire die do not need to be configured, so the die investment cost can be reduced. In addition, the structure of the biomass forming die is simple and easy to manufacture.

[0037] In the optional embodiment of the utility model, the compression surface 21 is inclined relative to the central axis of the compression channel 11, and / or the compression surface 21 is an arc surface.

[0038] The two ends of the compression channel 11 along its extension direction are respectively provided with an inlet 111 and an outlet 112, and the end of the compression surface 21 close to the inlet 111 is higher than the end of the compression surface 21 close to the outlet 112. During the briquetting of the biomass raw material, the biomass raw material enters the compression channel 11 from the inlet 111 and flows out from the outlet 112. During the briquetting of the biomass raw material, the compression direction of the biomass raw material can refer to the direction indicated by the arrow B. Fig. 3 The compression surface 21 is inclined relative to the central axis of the compression channel 11, and the angle of the compression surface 21 relative to the central axis of the compression channel 11 can be less than or equal to 30°, and can be 5°, 8°, 10°, 15°, 20°, 30°, etc. In the embodiment, the inclined compression surface 21 and / or the arc-shaped compression surface 21 can gradually increase the pressure on the biomass raw material during the compression process, and can gradually increase the friction between the biomass raw material and the inner wall of the compression channel 11, thereby ensuring the smoothness of the compression process.

[0039] In the optional embodiment of the utility model, the distance between the compression surface 21 and the outlet 112 is 0mm-10mm, preferably, the distance between the compression surface 21 and the outlet 112 is greater than or equal to 5mm and less than or equal to 10mm. The distance between the compression surface 21 and the outlet 112 can be 5mm, 6mm, 7mm, 8mm, 9mm, 10mm, etc. In the embodiment, the distance between the compression surface 21 and the outlet 112 is close, that is, when the biomass raw material is about to flow out from the outlet 112, the friction between the biomass raw material and the inner wall of the compression channel 11 is increased by the compression surface 21, thereby ensuring the effective utilization of the entire compression channel 11 as much as possible.

[0040] In the optional embodiment of the utility model, the extension depth of the compression surface 21 into the compression channel 11 along the first direction is greater than or equal to 0mm and less than or equal to 5mm.

The extension depth of the compression surface 21 into the compression channel 11 can be 0mm, 1mm, 2mm, 3mm, 4mm, 5mm, etc. In the embodiment, the extension depth of the compression surface 21 into the compression channel 11 can be adjusted within the range of 0mm to 5mm, thereby making the biomass forming mold flexible and applicable to various biomass raw materials, and thereby enhancing the application range of the biomass forming mold.

[0042] In the optional embodiment of the utility model, the cross section shape of compression channel 11 and the shape of compression surface 21 can be circular, square, trapezoidal, other quadrilateral, other irregular shape etc. Among them, when the cross section shape of compression channel 11 and the shape of compression surface 21 are square, the maximum width of compression surface 21 along the second direction is greater than or equal to 0.5 times the maximum width of compression channel 11 along the second direction, and less than the maximum width of compression channel 11 along the second direction. Among them, the second direction is perpendicular to the extension direction of compression channel 11, and is perpendicular to the height direction of mould main module 1. With W representing the maximum width of compression channel 11, then the maximum width of compression surface 21 can be 0.5W, 0.55W, 0.6W, 0.65W, 0.7W, 0.8W etc. In this embodiment, when the maximum width of compression surface 21 is within the above range, enough compression contact area can be provided for biomass raw material in the width direction, to ensure enough compression coverage area, so that the biomass raw material can be fully compacted in the width direction, to ensure the compression effect and finished product density.

[0043] In the optional embodiment of the utility model, the first direction is the height direction of mould main module 1, and the pressing block 2 is movably connected to the mould main module 1 along the height direction of the mould main module 1.

[0044] Among them, the upper through hole is located on the upper side of the compression channel 11, and the extension direction of the upper through hole is parallel to the height direction of the mould main module 1, and the pressing block 2 penetrates the upper through hole. The shape of the cross section of the upper through hole is matched with the shape of the cross section of the pressing block 2, and when the cross section of the pressing block 2 is circular, the cross section of the upper through hole is correspondingly circular. When the mould main module 1 is composed of a plurality of mould units 12, the upper through groove is formed by the upper through groove on the adjacent two mould units 12. In this embodiment, the moving distance of the compression surface 21 along the up-down direction is equal to the moving distance of the pressing block 2, and compared with the inclined arrangement of the pressing block 2, only a small amplitude movement of the pressing block 2 can realize the small amplitude up-down movement of the compression surface 21, and high efficiency adjustment can be realized.

[0046] The number of the support rods 4 can be determined according to the circumferential dimension of the biomass forming mold, for example, can be two, three, four, five, six, etc. The pressing plate 3 can be provided with a first threaded hole, the top of the pressing block 2 can be provided with an external thread, and the top of the pressing block 2 is screwed with the first threaded hole. The mold body module 1 can be provided with a second threaded hole, and the bottom of the support rod 4 can be screwed with the second threaded hole. When the mold body module 1 is composed of a plurality of mold units 12, at least one of the mold units 12 can be provided with a second threaded hole, and the second threaded hole is located between two compression grooves in a single mold unit 12.

In the embodiment, the pressing block 2 and the support rod 4 can be detached, so that when the pressing block 2 and the support rod 4 are not needed, the pressing block 2 and the support rod 4 can be removed.

[0047] When the number of the pressing blocks 2 is multiple, the multiple pressing blocks 2 are connected with the pressing plate 3, and the up-down positions of the multiple pressing blocks 2 can be simultaneously adjusted by adjusting the up-down position of one pressing plate 3, without adjusting the up-down positions of the multiple pressing blocks 2 one by one, so that the adjusting efficiency can be improved.
