Detailed Implementation

[0030] Exemplary embodiments of the present invention will now be described in more detail with reference to the accompanying drawings. While exemplary embodiments of the present invention are shown in the drawings, it should be understood that the present invention may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this invention will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.

[0031] Firstly, referring to Figure 1 This utility model discloses a biomass molding die, including a die main module 1 and a die auxiliary module 2. The die main module 1 has a first compression channel 11. The die auxiliary module 2 is detachably connected to the discharge side of the die main module 1. The die auxiliary module 2 has a second compression channel 21 corresponding to the first compression channel 11.

[0032] The biomass molding die is used in a briquetting equipment, which includes a die holder. The die main module 1 is detachably connected to the die holder. The die attachment module 2 can be connected to the die main module 1 by bolts, snap-fit, or other means. A first compression channel 11 extends through the die main module 1 along its extension direction, and a second compression channel 21 extends through the die attachment module 2 along its extension direction. The die main module 1 has multiple first compression channels 11, and the die attachment module 2 has multiple second compression channels 21. The positions of the second compression channels 21 correspond to the positions of the first compression channels 11, and the number of second compression channels 21 is equal to the number of first compression channels 11.

[0033] The second compression channel 21 and the first compression channel 11 together form the compression channel of the biomass molding die. The first compression channel 11 has a first inlet 111 and a first outlet 112 arranged opposite to each other along its extension direction, and the second compression channel 21 has a second inlet 211 and a second outlet 212 arranged opposite to each other along its extension direction. During the biomass raw material briquetting process, the biomass raw material enters the first compression channel 11 through the first inlet 111 and flows out of the first compression channel 11 through the first outlet 112, then flows into the second compression channel 21 through the second inlet 211, and finally flows out of the second compression channel 21 through the second outlet 212.

[0034] The main mold module 1 can be a one-piece structure or a separate structure. The additional mold module 2 can also be a one-piece structure or a separate structure. The overall shape of both the main mold module 1 and the additional mold module 2 can be ring-shaped, square, arc-shaped, U-shaped, etc. The discharge side of the main mold module 1 is the side of the main mold module 1 closest to the first discharge port 112. When the overall shape of the main mold module 1 is ring-shaped, the discharge side of the main mold module 1 is the outer periphery of the main mold module 1.

[0035] The compression ratio of a biomass molding die, also known as the length-to-diameter ratio, is specifically the ratio of the effective length of the compression channel of the biomass molding die to the characteristic dimensions (e.g., side length or diameter) of the compression channel's cross-section. The cross-section of the compression channel is the section perpendicular to its extension direction. When the biomass feedstock to be compressed changes, and the required compression ratio differs from that of the previous feedstock, by replacing different die attachment modules 2, the dimensions of the die attachment module 2 along the second compression channel 21 and / or the dimensions of the cross-section of the second compression channel 21 in the die attachment module 2 can be changed. This alters the effective length of the compression channel and / or the characteristic dimensions of the compression channel's cross-section, thereby changing the compression ratio of the biomass molding die.

[0036] In related technologies, the molds in biomass briquetting machines are typically one-piece molds with a fixed compression ratio, resulting in poor versatility. To meet the varying compression ratio requirements of different types of biomass raw materials, biomass briquetting machines need to be equipped with molds of various specifications, leading to high mold investment costs. When the biomass raw material to be compressed changes, and its required compression ratio differs from that of the previous raw material, the entire mold must be replaced to meet the current compression ratio requirements, making the operation complex and inefficient.

[0037] In this embodiment of the invention, by replacing different mold attachment modules 2, the effective length of the compression channel and / or the characteristic dimensions of the cross-section of the compression channel of the biomass molding die can be changed, thereby altering the compression ratio of the biomass molding die to meet the different compression ratio requirements of different types of biomass raw materials, thus enhancing the versatility of the biomass molding die. Furthermore, the mold attachment module 2 is located on the discharge side of the main mold module 1, facilitating replacement of the mold attachment module 2 and reducing its wear rate, thus extending its service life. Additionally, the briquetting equipment including this biomass molding die only requires the configuration of multiple specifications of mold attachment modules 2, reducing mold investment costs compared to configuring multiple specifications of the entire die. Moreover, changing the compression ratio of the biomass molding die only requires replacing different mold attachment modules 2, without needing to replace the main mold module 1, simplifying operation and improving replacement efficiency. Finally, the biomass molding die has a simple structure and is easy to manufacture.

[0038] In an optional embodiment of this utility model, reference is made to Figure 5 and Figure 6 Along the material discharge direction, the cross-sectional area of ​​at least part of the second compression channel 21 gradually decreases.

[0039] The material discharge direction is from the first inlet 111 in the same compression channel to the second outlet 212. The material discharge direction can be referred to as follows: Figures 5 to 7 The direction indicated by arrow B in the middle. (Refer to...) Figure 5 In one embodiment, along the material discharge direction, the cross-sectional area of ​​the entire second compression channel 21 gradually decreases, and the smallest cross-sectional area of ​​the second compression channel 21 is smaller than the cross-sectional area of ​​the first compression channel 11.

[0040] Reference Figure 6 In another embodiment, the second compression channel 21 includes a first compression section 213 and a second compression section 214. Along the material discharge direction, the cross-sectional area of ​​the first compression section 213 gradually decreases, and the smallest cross-sectional area of ​​the first compression section 213 is smaller than the cross-sectional area of ​​the first compression channel 11. The second compression section 214 is located on the side of the first compression section 213 away from the first compression channel 11. The cross-sectional area of ​​the second compression section 214 is uniform, and the cross-sectional area of ​​the second compression section 214 is equal to the smallest cross-sectional area of ​​the first compression section 213.

[0041] In this embodiment, along the material discharge direction, the cross-sectional area of ​​at least part of the second compression channel 21 gradually decreases. Therefore, the compression ratio of the biomass molding die can be changed by replacing the mold attachment module 2 with different dimensions along the extension direction of the second compression channel 21, or by replacing the mold attachment module 2 with different minimum cross-sectional areas of the second compression channel 21.

[0042] In the method of replacing the mold attachment module 2 with different minimum cross-sectional areas of the second compression channel 21, the principle of changing the compression ratio of the biomass molding die is to increase or decrease the characteristic dimensions of the cross-section of the compression channel of the biomass molding die. In this method, it is not necessary to change the dimensions of the mold attachment module 2 along the extension direction of the second compression channel 21, thereby fixing the overall dimensions of the biomass molding die and saving the installation space reserved for the mold attachment module 2 with the largest dimensions along the extension direction of the second compression channel 21 in the briquetting equipment.

[0043] The cross-sectional shape of the first compression channel 11 can be circular, square, trapezoidal, other quadrilaterals, or other irregular shapes. The cross-sectional shape of the second compression channel 21 can also be circular, square, trapezoidal, other quadrilaterals, or other irregular shapes. The cross-sectional shape of the second compression channel 21 may be the same as or different from that of the first compression channel 11. Preferably, the cross-sectional shape of the second compression channel 21 is the same as that of the first compression channel 11. The cross-sectional shapes of both the second compression channel 21 and the first compression channel 11 are preferably square. The square arrangement of the second compression channel 21 and the first compression channel 11 can reduce the wear rate of the biomass molding die and improve the production efficiency of the briquetting equipment including the biomass molding die.

[0044] When the cross-sectional shape of the second compression channel 21 is circular, the minimum cross-sectional area of ​​the second compression channel 21 can be changed by changing the minimum diameter of the second compression channel 21 in different mold attachment modules 2. When the cross-sectional shape of the second compression channel 21 is square, the minimum cross-sectional area of ​​the second compression channel 21 can be changed by changing the minimum side length of the second compression channel 21 in different mold attachment modules 2.

[0045] In an optional embodiment of this utility model, reference is made to Figure 5 and Figure 6 Along the material discharge direction, at least part of the inner wall of the second compression channel 21 has an angle greater than zero with respect to the central axis of the second compression channel 21, and the angle is between 1° and 30°.

[0046] Reference Figure 5 In one embodiment, along the material discharge direction, the angle between the inner wall of the entire second compression channel 21 and the central axis of the second compression channel 21 is greater than zero. The angle between the inner wall of the entire second compression channel 21 and the central axis of the second compression channel 21 can be referenced... Figure 5 The angle α shown is 1°-30°, specifically 1°, 5°, 8°, 10°, 20°, 30°, etc.

[0047] Reference Figure 6 In another embodiment, the second compression channel 21 includes a first compression section 213. Along the material discharge direction, the angle between the inner wall of the first compression section 213 and the central axis of the second compression channel 21 is greater than zero. The angle between the inner wall of the first compression section 213 and the central axis of the second compression channel 21 can be referenced... Figure 6 The angle of β shown is 1°-30°, specifically 1°, 8°, 10°, 15°, 20°, 30°, etc.

[0048] In an optional embodiment of this utility model, reference is made to Figure 1and Figure 2 The main mold module 1 is composed of multiple first mold units 12, and the additional mold module 2 is composed of multiple second mold units 22. The second mold units 22 are detachably connected to the discharge side of the first mold unit 12.

[0049] The plurality of first mold units 12 are preferably arranged in a circular array, and the plurality of second mold units 22 are preferably arranged in a circular array. Two adjacent first mold units 12 may be unconnected, and two adjacent second mold units 22 may be unconnected. The connection method between the second mold unit 22 and the first mold unit 12 can be bolt connection, snap-fit ​​connection, etc.

[0050] In this embodiment, the main mold module 1 is assembled from multiple first mold units 12, and the additional mold module 2 is assembled from multiple second mold units 22. When the mold is worn, only a single first mold unit 12 or second mold unit 22 needs to be replaced, which can reduce maintenance costs and improve maintenance efficiency.

[0051] In an optional embodiment of the present invention, a first compression groove 121 is provided on the first mold unit 12, and two adjacent first compression grooves 121 are combined to form a first compression channel 11. A second compression groove 221 is provided on the second mold unit 22, and two adjacent second compression grooves 221 are combined to form a second compression channel 21.

[0052] The first compression channel 121 has a first feed opening 1211 and a first discharge opening arranged opposite to each other along its extension direction. Two adjacent first feed openings 1211 are combined to form a first feed port 111, and two adjacent first discharge openings are combined to form a first discharge port 112. The discharge side of the first mold unit 12 is the side of the first mold unit 12 closest to the first discharge opening. The second compression channel 221 has a second feed opening and a second discharge opening 2211 arranged opposite to each other along its extension direction. Two adjacent second feed openings are combined to form a second feed port 211, and two adjacent second discharge openings 2211 are combined to form a second discharge port 212.

[0053] In this embodiment, two adjacent first compression channels 121 are joined together to form a first compression channel 11, and two adjacent second compression channels 221 are joined together to form a second compression channel 21. Compared with the method of integrally processing the first compression channel 11 and the second compression channel 21, the processing difficulty of the first compression channel 11 and the second compression channel 21 in the biomass molding die can be reduced.

[0054] In an optional embodiment of this utility model, reference is made to Figure 4 The cross-sectional area of ​​the second compression channel 21 is uniform.

[0055] In this embodiment, the cross-section of the first compression channel 11 is perpendicular to its extension direction, and the cross-section of the second compression channel 21 is perpendicular to its extension direction. Preferably, the area of ​​the cross-section of the second compression channel 21 is equal to the area of ​​the cross-section of the first compression channel 11. In this case, the compression ratio of the biomass molding die is changed by replacing different mold attachment modules 2 with different dimensions along the extension direction of the second compression channel 21. The principle of changing the compression ratio of the biomass molding die in this method is to increase or decrease the effective length of the compression channel of the biomass molding die. In this embodiment, the shape of the second compression channel 21 is simple and easy to manufacture. Furthermore, the uniform cross-sectional area of ​​the second compression channel 21 ensures the uniformity of compression during the biomass raw material compression process, which is beneficial for improving the quality and consistency of the finished product.

[0056] In an optional embodiment of this utility model, reference is made to Figure 2 The length of the second mold unit 22 along the length direction of the second compression groove 221 is greater than or equal to 10 mm and less than or equal to 120 mm.

[0057] The length direction of the second compression channel 221 is parallel to the length direction of the first compression channel 121. The length direction of the second compression channel 221 can be referred to... Figure 2 The direction indicated by arrow A in the middle. The length of the second mold unit 22 along the length direction of the second compression channel 221 can be less than or equal to the length of the first mold unit 12 along the length direction of the first compression channel 121, and the length of the second mold unit 22 along the length direction of the second compression channel 221 can also be greater than the length of the first mold unit 12 along the length direction of the first compression channel 121.

[0058] The length of the second mold unit 22 along the length direction of the second compression channel 221 can be 10mm, 15mm, 20mm, 30mm, 50mm, 70mm, 100mm, 120mm, etc. By replacing the second mold unit 22 with different lengths, different sizes of the mold auxiliary module 2 along the length direction of the second compression channel 21 can be replaced, thereby changing the effective length of the compression channel of the biomass molding die and thus changing the compression ratio of the biomass molding die. For example, by replacing it with a longer second mold unit 22, the effective length of the compression channel of the biomass molding die can be extended, the compression density of the biomass molding die can be increased, and thus the compression ratio of the biomass molding die can be increased. In this embodiment, by providing various length specifications of the second mold unit 22 in the range of 10mm to 120mm, the second mold unit 22 can be flexibly applied to various biomass raw materials, thereby enhancing the applicability of the biomass molding die.

[0059] In an optional embodiment of this utility model, reference is made to Figure 2 A first positioning structure is provided on the first end face 122 of the first mold unit 12 near the second mold unit 22, and a second positioning structure is provided on the second end face 222 of the second mold unit 22 near the first mold unit 12. The first positioning structure and the second positioning structure cooperate with each other.

[0060] The first positioning structure can be a groove, hole, etc., and the second positioning structure can be a protrusion, pin, etc. The second positioning structure can be a groove, hole, etc., and the first positioning structure can be a protrusion, pin, etc. The first mold unit 12 has a first end face 122 near the second mold unit 22, and the first positioning structure is disposed on the first end face 122. The second mold unit 22 has a second end face 222 near the first mold unit 12, and the second positioning structure is disposed on the second end face 222.

[0061] In this embodiment, the alignment accuracy of the first compression channel 11 and the second compression channel 21 is improved by setting the first positioning structure and the second positioning structure, thereby ensuring that the overall compression channel is flat and guaranteeing smooth compression of biomass raw materials. In addition, after the second mold unit 22 is connected to the first mold unit 12, the first end face 122 contacts the second end face 222, and the first positioning structure and the second positioning structure are hidden inside the biomass molding mold, which can improve the compactness and aesthetics of the biomass molding mold.

[0062] In an optional embodiment of this utility model, reference is made to Figure 2 The first positioning structure is a positioning groove 123, and the second positioning structure is a positioning protrusion 223, which extends into the positioning groove 123.

[0063] The positioning protrusion 223 protrudes from the second end face 222. The protrusion height of the positioning protrusion 223 can be set according to actual needs, and this embodiment does not impose any restrictions on it. The shape of the positioning protrusion 223 can be square, circular, arc-shaped, triangular, etc. The shape and size of the positioning groove 123 match the shape and size of the positioning protrusion 223. The number of positioning grooves 123 is equal to the number of positioning protrusions 223. Preferably, there are two positioning protrusions 223 in a single second mold unit 22, and the two positioning protrusions 223 are respectively close to the two second compression through grooves 221. The structure of the positioning groove 123 and the positioning protrusion 223 is simple and easy to manufacture.

[0064] In an optional embodiment of this utility model, reference is made to Figure 3The second mold unit 22 has a mounting hole 224 that extends through the second mold unit 22 along the length of the second compression groove 221. The mounting hole 224 is used for mounting the second mold unit 22. In this embodiment, the second mold unit 22 is installed and removed along the length of the second compression groove 221, which facilitates the installation and removal of the second mold unit 22.

[0065] In an optional embodiment of this utility model, reference is made to Figure 3 The biomass molding die also includes a fastener 3; the head of the fastener 3 extends into the mounting hole 224, and / or, the first mold unit 12 has a threaded hole 124, the fastener 3 passes through the mounting hole 224 and is threadedly connected to the threaded hole 124.

[0066] The number of fasteners 3 connecting a single first mold unit 12 and a single second mold unit 22 can be set according to actual needs, such as one, two, three, four, etc. The number of threaded holes 124 on a single first mold unit 12 and the number of mounting holes 224 on a single second mold unit 22 are equal to the number of fasteners 3 connecting the single first mold unit 12 and the single second mold unit 22. For example, when the number of fasteners 3 connecting the single first mold unit 12 and the single second mold unit 22 is three, the number of threaded holes 124 on the single first mold unit 12 is three, and the number of mounting holes 224 on the single second mold unit 22 is three.

[0067] Each first mold unit 12 has two first compression grooves 121, and a threaded hole 124 is located between the two first compression grooves 121. Each second mold unit 22 has two second compression grooves 221, and a mounting hole 224 is located between the two second compression grooves 221. The fastener 3 can be a bolt, screw, etc. The mating length between the fastener 3 and the threaded hole 124 can be 15mm-20mm.

[0068] In this embodiment, the head of the fastener 3 extends into the mounting hole 224, which avoids the head of the fastener 3 protruding and causing the overall size of the biomass molding die to increase, thereby ensuring the compactness of the biomass molding die. In addition, the first mold unit 12 and the second mold unit 22 are connected by the fastener 3, which has a simple structure, high connection reliability, and facilitates the replacement of the second mold unit 22.

[0069] Secondly, this utility model embodiment also discloses a briquetting device, including the biomass molding die provided in the first aspect. Since the briquetting device includes the aforementioned biomass molding die, it also possesses the beneficial effects of the aforementioned biomass molding die, which will not be elaborated upon here.

[0070] The briquetting equipment may also include a mold fixing base, and the main mold module 1 of the biomass briquetting mold is detachably connected to the mold fixing base. A mounting through hole 125 is provided on the first mold unit 12, and a bolt passes through the mounting through hole 125, allowing the first mold unit 12 to be connected to the mold fixing base via the bolt. Each first mold unit 12 has two first compression slots 121, and the mounting through hole 125 is located between the two first compression slots 121.
