[0053] The present disclosure will be described further to specific embodiments below, with reference made to the accompanying drawings. It is to be noted that technical features involved in each of the embodiments of the present disclosure described below can be combined with each other as long as there is no conflict. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to explain the present disclosure, and should not be construed as limiting the present disclosure.

[0054] Biomass energy, as the fourth largest energy resource, plays an important role in renewable energy. Biomass energy is renewable, low-polluting, and widely distributed. Biomass fuel is a new type of clean fuel that can be directly combusted, which is made of agricultural waste and wood waste as raw materials through processes such as crushing, mixing, extruding, and drying into various forms (such as blocks, granules, etc.).

[0055] However, the current biomass fuel forming production line has corresponding independent control system for each device, and the actual monitoring value of the raw material can be used to adjust the technical parameters of the corresponding device in the field production. However, because the process is more and the control system is more dispersed, the workload of the field device monitoring operator is large. Moreover, the control systems of the devices are independently operated, and for the production process of the whole production line, the connection between the sections is not smooth, production is waiting, production efficiency is low, and production resources are wasted.

[0056] To solve the above technical problems, as shown in Figures 1 to 2 The present disclosure provides a biomass fuel forming production line, which at least comprises: a crushing section, a drying section, a forming section and a centralized control system 1.

[0057] The crushing section is used for crushing the biomass raw material into intermediate products. The crushing section comprises a first monitoring structure for monitoring the working frequency of the crushing section.

[0058] It should be noted that the crushing section can be crushing and / or pulverizing of the biomass raw material, which can be processed according to the different forms of the biomass raw material. For example, the biomass raw material can be first crushed and then pulverized, or the biomass raw material can be directly pulverized.

[0059] The drying section is located downstream of the crushing section for receiving and drying the intermediate products. The drying section comprises a second monitoring structure for monitoring the working frequency of the drying section.

[0060] The forming section is located downstream of the drying section for receiving and extruding the dried intermediate products to form solid fuel products. The forming section comprises a third monitoring structure for monitoring the working frequency of the forming section.

[0061] It should be noted that the forming section can be granulation or briquetting of the dried intermediate products. Both granulation and briquetting belong to the forming method of the biomass raw material, and the corresponding forming treatment can be performed according to the type of the intermediate product (or biomass raw material).

[0062] The centralized control system 1 is connected with the first monitoring structure, the second monitoring structure and the third monitoring structure for receiving the working frequencies of the crushing section, the drying section and the forming section, and for controlling and adjusting the working frequencies of the crushing section, the drying section and the forming section, so that the working frequencies of the crushing section, the drying section and the forming section are adapted to each other, to ensure the dynamic balance of the biomass fuel forming production line.

[0063] It should be noted that the "working frequency" in the above refers to the hourly production capacity of the corresponding section, or the speed of feeding and discharging of each section.

[0064] The "dynamic balance" refers to an average of all sections of the biomass fuel molding production line, adjusting the working frequency of each section to make the operation time of each section as close as possible, so that the operation load between sections is balanced.

[0065] That is, when the working frequency of one section in the present disclosure changes, the working frequencies of the other sections also change, so that the working frequencies of each section are adapted, and the dynamic balance of the biomass fuel molding production line is ensured.

[0066] Generally, to achieve the dynamic balance of the biomass fuel molding production line, when the working frequency of the drying section decreases, the working frequencies of the crushing section and the molding section also decrease.

[0067] In addition, the moisture content of different types of biomass raw materials and the suitable moisture content after processing and molding are different. In order to produce fuel products suitable for different molding requirements, the working frequency of each section can be adjusted according to the type of biomass raw material and the actual moisture content of the biomass raw material.

[0068] The first monitoring structure, the second monitoring structure, and the third monitoring structure of the embodiment of the present disclosure integrate the working frequencies of the crushing section, the drying section, and the molding section on the centralized control system 1 respectively. The centralized control system 1 can display the working frequencies of each section monitored in real time. According to the corresponding working frequencies of each section, the production personnel can adjust the equipment of each process in time through the centralized control system 1. The connection between each section is smooth, reducing the production waiting time and the occurrence of production abnormalities, thereby improving the production efficiency and saving production resources. In addition, the centralized control of each section by the centralized control system 1 can also reduce the configuration of production operation personnel and the workload of the on-site monitoring operation personnel of each section. While ensuring the safe, efficient, and economic operation of the entire biomass fuel molding production line, it can also reduce or avoid the problem of abnormal damage or even scrap of each device caused by long-term operation in an abnormal state, thereby reducing the loss of enterprises.

[0069] It should be noted that in addition to monitoring the working frequency on the corresponding section, the first monitoring structure, the second monitoring structure, and the third monitoring structure can also be used to monitor the working voltage and the working current on the corresponding section, and can transmit the working voltage and the working current on each section to the centralized control system 1. The centralized control system 1 can control and adjust the working voltage and the working current of the crushing section, the drying section, and the molding section, so that the working voltage and the working current of the crushing section, the drying section, and the molding section are adapted, to ensure the dynamic balance of the biomass fuel molding production line.

[0070] Specifically, the crushing section in the embodiments of the present disclosure can include a crushing device 4, which is used to crush the biomass raw material. The first monitoring structure is used to monitor the working frequency (corresponding to f4 in the formula (1)) of the crushing device 4 and transmit the working frequency of the crushing device 4 to the centralized control system 1, so that the working frequency of the crushing device 4 receives the control of the centralized control system 1. Figure 2

[0071] In the present disclosure, the motor can be used as the power element of the crushing device 4. At this time, the first monitoring structure is used to monitor the real-time frequency of the motor, and the centralized control system 1 receives the real-time frequency of the motor transmitted by the first monitoring structure and is used to control and adjust the real-time frequency of the motor, so as to realize the control and adjustment of the working frequency of the crushing device 4.

[0072] Further, the crushing section can also include a first conveying belt 2, which is used to convey the biomass raw material to the crushing device 4.

[0073] Specifically, the biomass raw material can be transferred to the first conveying belt 2 by a forklift, and the first conveying belt 2 conveys the biomass raw material to the crushing device 4 to process the irregular biomass raw material into block-shaped, silk-shaped or strip-shaped materials that are beneficial to molding.

[0074] It should be noted that the biomass raw material in the present disclosure can be raw wood, wood scraps and the like.

[0075] In the present disclosure, the first monitoring structure is used to monitor the working frequency (corresponding to f2 in the formula (1)) of the first conveying belt 2 and transmit the working frequency of the first conveying belt 2 to the centralized control system 1. The first conveying belt 2 is signal connected with the centralized control system 1 and is used to receive the control adjustment of the centralized control system 1, so that its working frequency is adapted to the working frequency of the crushing device 4. Figure 2

[0076] In the present disclosure, the motor can be used as the power element of the first conveying belt 2. At this time, the first monitoring structure is used to monitor the real-time frequency of the motor, and the centralized control system 1 is used to receive the real-time frequency of the motor and control and adjust the real-time frequency of the motor, so as to realize the control and adjustment of the working frequency of the first conveying belt 2.

[0077] In addition, the crushing section can also include a first feeding screw conveyor 3, which can be used to convey the biomass raw material to the crushing device 4.

[0078] ​​Specifically, the biomass raw material can be transported by a forklift to the first feeding screw conveyor 3, and the first feeding screw conveyor 3 delivers the biomass raw material to the crushing device 4 to process the irregular biomass raw material into blocks, filaments or strips that are beneficial to molding. The outlet end of the first feeding screw conveyor 3 matches the feeding port of the crushing device 4 to facilitate the smooth entry of the biomass raw material into the crushing device 4. In addition, the first feeding screw conveyor 3 can also mix and stir the biomass raw material during the transportation process to improve the overall production efficiency of the biomass fuel molding production line.

[0079] In the present disclosure, the first monitoring structure is used to monitor the working frequency (corresponding to f3 in the formula (1)) of the first feeding screw conveyor 3 and to transmit the working frequency of the first feeding screw conveyor 3 to the centralized control system 1. The first feeding screw conveyor 3 is signal-connected to the centralized control system 1 and is used to receive the control adjustment of the centralized control system 1 to adapt the working frequency of the first feeding screw conveyor 3 to the working frequency of the crushing device 4. Figure 2

[0080] The power component of the first feeding screw conveyor 3 can be a motor, in which case the first monitoring structure is used to monitor the real-time frequency of the motor, and the centralized control system 1 is used to receive the real-time frequency of the motor and to control and adjust the real-time frequency of the motor, thereby achieving control and adjustment of the working frequency of the first feeding screw conveyor 3.

[0081] Of course, the present disclosure can also simultaneously provide the crushing device 4, the first conveying belt 2 and the first feeding screw conveyor 3 in the crushing section, in which case the biomass raw material is transported by a forklift to the first conveying belt 2, and the first feeding screw conveyor 3 receives the biomass raw material from the first conveying belt 2 and then delivers the biomass raw material to the crushing device 4 for crushing.

[0082] It should be noted that in the crushing section, the first monitoring structure can be used to monitor the working voltage and working current of the crushing device 4, the first conveying belt 2, the first feeding screw conveyor 3 and the corresponding motor in addition to the working frequency, and to transmit the monitoring data to the centralized control system 1. The crushing device 4, the first conveying belt 2, the first feeding screw conveyor 3 and the corresponding motor are signal-connected to the centralized control system 1 and are used to receive the control adjustment of the centralized control system 1 to achieve control and adjustment of the working voltage and working current of the crushing device 4, the first conveying belt 2, the first feeding screw conveyor 3 and the corresponding motor through the centralized control system 1, thereby ensuring the dynamic balance of the biomass fuel molding production line.

[0083] As shown in FIG. 1, the biomass fuel molding production line comprises a centralized control system 1, a first conveying belt 2, a first feeding screw conveyor 3, a crushing device 4, a second conveying belt 5, a molding device 6, a drying device 7 and a screening device 8. Figure 2 ​As shown, the working voltage of the first conveying belt 2 is U2, the working current of the first conveying belt 2 is I2, the working voltage of the first feeding screw conveyor 3 is U3, the working current of the first feeding screw conveyor 3 is I3, the working voltage of the crushing device 4 is U4, and the working current of the crushing device 4 is I4.

[0084] It should be further noted that the first monitoring structure in the present disclosure can include a plurality of monitors. For example, the present disclosure can be provided with one monitor on the crushing device 4, the first conveying belt 2, the first feeding screw conveyor 3, and the corresponding motor, respectively, for monitoring the working parameters (for example: working frequency, working voltage, working current, etc.) of each device.

[0085] In the embodiments of the present disclosure, the drying section can include a drying device 7, which is used to receive and dry the intermediate product formed by the crushing section. The second monitoring structure is used to monitor the working frequency (f7) of the drying device 7 and transmit the working frequency of the drying device 7 to the centralized control system 1, so that the working frequency of the drying device 7 receives the control of the centralized control system 1.

[0086] In the present disclosure, the motor can be used as the power element of the drying device 7. At this time, the second monitoring structure is used to monitor the real-time frequency of the motor, and the centralized control system 1 receives the real-time frequency of the motor transmitted by the second monitoring structure and is used to control and adjust the real-time frequency of the motor, so as to realize the control and adjustment of the working frequency of the drying device 7.

[0087] In some embodiments of the present disclosure, the drying device 7 can include a drying furnace, and the second monitoring structure can include a humidity monitor for real-time monitoring of the humidity inside the drying furnace (corresponding to %7 in the present disclosure). Figure 2 The humidity monitor is used to transmit the humidity signal inside the drying furnace to the centralized control system 1. The centralized control system 1 is used to adjust the working frequency of the drying device 7 according to the obtained humidity inside the drying furnace, so as to make the inside of the drying furnace reach the preset working humidity.

[0088] The humidity monitor can be arranged inside the drying furnace.

[0089] It is to be explained that the moisture content of the biomass raw material is a key indicator in the entire molding process, and too high or too low moisture content will affect the molding degree of the raw material, and even cannot be formed; at the same time, too low moisture content will also increase the production cost input of the drying section and the cost of raw material procurement, causing waste and increase of the entire production cost. The drying equipment 7 mainly uses heat energy to process the moisture in the intermediate product fragmented from the biomass raw material, and reduces the moisture content of the intermediate product to prepare for the subsequent molding of the fuel finished product. Therefore, the present disclosure can set a preset working humidity inside the drying furnace according to the type of the biomass raw material, and when the humidity monitor detects that the inside of the drying furnace reaches the preset working humidity, it means that the intermediate product has also been dried to a moisture content suitable for processing into a fuel finished product.

[0090] Generally speaking, the greater the humidity inside the drying furnace, the greater the humidity of the intermediate product inside the drying furnace, at which time the working frequency of the drying equipment 7 can be reduced to increase the drying time of the intermediate product inside the drying furnace, so as to more fully dry the intermediate product until the inside of the drying furnace reaches the preset working humidity.

[0091] In some other embodiments of the present disclosure, the drying equipment 7 can include a drying furnace, which, when working, can have a first preset working temperature inside. The second monitoring structure can include a first temperature monitor for monitoring the temperature inside the drying furnace in real time (corresponding to t7 in FIG. 7). Figure 2 The first temperature monitor is used to transmit the temperature signal inside the drying furnace to the centralized control system 1, so that the inside of the drying furnace is maintained at the first preset working temperature by the centralized control system 1.

[0092] Specifically, the drying equipment 7 can include a drying cylinder having a cylinder body for accommodating the intermediate product. The intermediate product formed after fragmentation in the fragmentation section enters the cylinder body from the feed port head of the drying cylinder, and the drying furnace is used to provide a heat source for the drying cylinder. The drying cylinder can be rotated under the driving of the motor, and the wet intermediate product entering the drying cylinder is repeatedly lifted and dropped by the lifting plate on the cylinder wall. With the help of hot air inside the cylinder and the rotation of the drying cylinder, the moisture in the intermediate product can be reduced.

[0093] When the temperature inside the drying furnace exceeds the first preset working temperature, the heat supply of the drying furnace can be reduced, so that the risk of fire or dust explosion of the intermediate product due to too high temperature can be avoided.

[0094] If the internal temperature of the drying furnace exceeds the first preset working temperature, and the internal temperature of the drying furnace cannot be quickly reduced to the first preset working temperature by reducing the heat supply of the drying furnace in a short time, the centralized control system 1 can control the corresponding equipment to stop running, so as to reduce or avoid dangerous situations such as combustion and explosion of the intermediate product and the equipment. After the drying equipment 7 stops running, the crushing section and the forming section reduce the working frequency or stop running, and after the internal temperature of the drying furnace is detected to be normal, the working frequency of the drying equipment 7 is adjusted again to restart, so that the biomass fuel forming production line reaches dynamic balance again.

[0095] It should be pointed out that the first temperature monitor in the present disclosure can be arranged in the drying furnace.

[0096] In the embodiment of the present disclosure, the drying section can further include a second conveying belt 5, which is used to convey the intermediate product formed after the biomass raw material is crushed to the drying equipment 7.

[0097] Specifically, the intermediate product formed after being crushed by the crushing section is conveyed to the drying equipment 7 by the second conveying belt 5 for drying, so as to reduce the moisture content of the intermediate product.

[0098] In the present disclosure, the second monitoring structure is used to monitor the working frequency (corresponding to f5 in the formula) of the second conveying belt 5, and is used to transmit the working frequency of the second conveying belt 5 to the centralized control system 1. The second conveying belt 5 is signal connected with the centralized control system 1, and is used to receive the control adjustment of the centralized control system 1, so that the working frequency thereof is adapted to the working frequency of the drying equipment 7.

[0099] Among them, the power member of the second conveying belt 5 can be a motor, at this time, the second monitoring structure is used to monitor the real-time frequency of the motor, and the centralized control system 1 is used to receive the real-time frequency of the motor and control adjustment of the real-time frequency of the motor, so that the control adjustment of the working frequency of the second conveying belt 5 can be realized.

[0100] In addition, the crushing section can further include a second feeding screw conveyor 6, which can be used to convey the intermediate product formed after the biomass raw material is crushed to the drying equipment 7.

[0101] Specifically, the intermediate product formed after being crushed by the crushing section is conveyed to the drying equipment 7 by the second feeding screw conveyor 6 for drying. Among them, the outlet end of the second feeding screw conveyor 6 matches the feeding port of the drying equipment 7, so as to facilitate the smooth entry of the intermediate product into the drying equipment 7. In addition, the second feeding screw conveyor 6 can also mix and stir the intermediate product during the transportation of the intermediate product to the drying equipment 7, so as to improve the overall production efficiency of the biomass fuel forming production line.

[0102] ​In this disclosure, the second monitoring structure is used to monitor the operating frequency (corresponding to) of the second feed screw conveyor 6. Figure 2 f6 in the middle), and is used to transmit the working frequency of the second feeding screw conveyor 6 to the centralized control system 1. The second feeding screw conveyor 6 is connected to the centralized control system 1 by signal and is used to receive the control adjustment of the centralized control system 1 so that its working frequency is adapted to the working frequency of the drying equipment 7.

[0103] The power component of the second feeding screw conveyor 6 can be a motor. In this case, the second monitoring structure is used to monitor the real-time frequency of the motor, and the centralized control system 1 is used to receive the real-time frequency of the motor and control and adjust the real-time frequency of the motor, thereby realizing the control and adjustment of the working frequency of the second feeding screw conveyor 6.

[0104] Of course, this disclosure can also simultaneously install drying equipment 7, second conveyor belt 5 and second feeding screw conveyor 6 in the drying section. In this case, the intermediate product formed after crushing in the crushing section enters the second conveyor belt 5. After receiving the intermediate product from the second conveyor belt 5, the second feeding screw conveyor 6 transmits the intermediate product to the drying equipment 7 for drying.

[0105] It should be noted that in the drying section, the second monitoring structure, in addition to monitoring the operating frequency of the drying equipment 7, the second conveyor belt 5, the second feeding screw conveyor 6, and the corresponding motors, can also monitor the operating voltage and current of the drying equipment 7, the second conveyor belt 5, the second feeding screw conveyor 6, and the corresponding motors, and transmit the monitoring data to the centralized control system 1. The drying equipment 7, the second conveyor belt 5, the second feeding screw conveyor 6, and the corresponding motors are all connected to the centralized control system 1 and are used to receive control adjustments from the centralized control system 1. Through the centralized control system 1, the operating voltage and current of the drying equipment 7, the second conveyor belt 5, the second feeding screw conveyor 6, and the corresponding motors are controlled and adjusted, thereby ensuring the dynamic balance of the biomass fuel briquetting production line.

[0106] like Figure 2 As shown, the operating voltage of the second conveyor belt 5 is U5, the operating current of the second conveyor belt 5 is I5, the operating voltage of the second feeding screw conveyor 6 is U6, the operating current of the second feeding screw conveyor 6 is I6, the operating voltage of the drying equipment 7 is U7, and the operating current of the drying equipment 7 is I7.

[0107] It should also be noted that the second monitoring structure in this disclosure may include multiple monitors. For example, this disclosure may install a monitor on the drying equipment 7, the second conveyor belt 5, the second feeding screw conveyor 6, and the corresponding motor, respectively, to monitor the operating parameters of each device (e.g., operating frequency, operating voltage, operating current, temperature, humidity, etc.).

[0108] In the embodiments of the present disclosure, the forming section can include a forming device 10, which is used to receive and extrude the dried intermediate product to form a fuel product. The third monitoring structure is used to monitor the working frequency of the forming device 10 (corresponding to f10 in Figure 2

[0109] In the present disclosure, the motor can be used as the power element of the forming device 10. At this time, the third monitoring structure is used to monitor the real-time frequency of the motor, and the centralized control system 1 is used to receive the real-time frequency of the motor transmitted by the third monitoring structure and to control and adjust the real-time frequency of the motor, so as to realize the control and adjustment of the working frequency of the forming device 10.

[0110] It should be noted that the forming device 10 is the forming device of the intermediate product, and the operation of the forming device 10 is driven by the rotation of the gear shaft driven by the motor. The working environment of the forming device 10 is mostly high temperature, high humidity and high dust state, so the gears and transmission shafts and other parts need to be kept in a lubricated state at all times, otherwise the equipment will be abnormally worn due to poor lubrication, and the service life of the equipment will be reduced. The forming device 10 mainly forms the intermediate product with a suitable water content by extrusion between the molds to produce fuel products suitable for different forming requirements.

[0111] In some embodiments of the present disclosure, the forming device 10 can include a gear box, which can have a second preset working temperature inside when working. The third monitoring structure includes a second temperature monitor for real-time monitoring of the temperature inside the gear box (corresponding to t10 in Figure 2

[0112] It should be understood that when the gear box is working, the temperature inside the gear box is related to the supply amount of lubricating oil: when the supply amount of lubricating oil is insufficient, the lubrication of the gears and bearings of the gear box will be insufficient, which will in turn cause the increase of friction and wear. This increased friction will generate more heat, causing the temperature inside the gear box to rise. As the temperature rises, the lubricating oil can become more dilute, and its lubricating performance will also decrease, further exacerbating the wear of the gears and bearings.

[0113] ​​This disclosure uses a second temperature monitor to monitor the temperature inside the gearbox in real time. When the temperature inside the gearbox exceeds a second preset operating temperature, it can predict that the lubricating oil supply is insufficient, thereby increasing the lubricating oil supply to reduce gearbox wear, lower the temperature inside the gearbox, reduce gearbox maintenance costs, and increase its service life.

[0114] If the internal temperature of the gearbox exceeds the second preset operating temperature, and it is impossible to quickly reduce the internal temperature to the second preset operating temperature by increasing the supply of lubricating oil within a short period of time, the centralized control system 1 can control the corresponding equipment to stop operating to reduce abnormal wear of the gearbox. After the molding equipment 10 stops operating, the crushing section and drying section reduce their operating frequency or stop operating. After the internal temperature of the gearbox is detected to return to normal, the operating frequency of the molding equipment 10 is readjusted and restarted to allow the biomass fuel molding production line to reach dynamic balance again.

[0115] It should be noted that the second temperature monitor in this disclosure can be located inside the gearbox.

[0116] In other embodiments of this disclosure, the molding apparatus 10 may include a gearbox, which may have a preset working pressure inside during operation. A third monitoring structure may include a pressure monitor for real-time monitoring of the pressure inside the gearbox (corresponding to...). Figure 2 (P10 in the document). The pressure monitor is used to transmit the pressure signal inside the gearbox to the centralized control system 1, so that the centralized control system 1 can maintain the gearbox at a preset working pressure.

[0117] It should be noted that the internal pressure of a gearbox during operation is also related to the supply of lubricating oil: when there is too little lubricating oil, the gears and bearings will not be adequately lubricated, leading to increased friction and wear, and generating more heat, causing the internal temperature of the gearbox to rise. As the temperature rises, some components inside the gearbox (such as seals, pressure valves, etc.) may fail or degrade in performance, thus causing the internal pressure to increase.

[0118] This disclosure uses a pressure monitor to monitor the pressure inside the gearbox in real time. When the pressure inside the gearbox exceeds the preset working pressure, it can predict that the lubricating oil supply is insufficient, thereby increasing the supply of lubricating oil to reduce gearbox wear, which in turn reduces the pressure inside the gearbox, reduces the maintenance cost of the gearbox, and increases its service life.

[0119] Similarly, if the internal temperature of the gear box exceeds the preset working pressure and the internal temperature of the gear box cannot be quickly reduced to the preset working pressure by increasing the supply of lubricating oil in a short time, the centralized control system 1 can control the corresponding equipment to stop running to reduce the abnormal wear of the gear box. After the forming equipment 10 stops running, the crushing section and the drying section reduce the working frequency or stop running, and after the internal temperature of the gear box is detected to return to normal, the working frequency of the forming equipment 10 is adjusted again to restart, so that the biomass fuel forming production line reaches dynamic balance again.

[0120] In the present disclosure, the pressure monitor can be arranged in the gear box.

[0121] In the present disclosure, the forming section can further include a third conveying belt 8 for conveying the dried intermediate product to the forming equipment 10.

[0122] Specifically, the intermediate product output from the drying equipment 7 is conveyed to the forming equipment 10 through the third conveying belt 8, and the intermediate product enters the pressing die warehouse, and the rotation of the pressing wheel makes the intermediate product uniformly distributed on the surface of the die cavity. Under the rolling of the pressing roller, the intermediate product passes through the hole of the die, so as to form the fuel product with the required shape. In the present disclosure, the shape of the fuel product can be cylindrical or block solid, etc. The specific shape can be determined according to the actual situation.

[0123] In the present disclosure, the third monitoring structure is used to monitor the working frequency of the third conveying belt 8 (corresponding to f8 in the formula (1)), and is used to transmit the working frequency of the third conveying belt 8 to the centralized control system 1. The third conveying belt 8 is signal connected with the centralized control system 1, and is used to receive the control adjustment of the centralized control system 1, so that the working frequency thereof is adapted to the working frequency of the forming equipment 10. Figure 2

[0124] In the present disclosure, the power member of the third conveying belt 8 can be a motor, and at this time, the third monitoring structure is used to monitor the real-time frequency of the motor, and the centralized control system 1 is used to receive the real-time frequency of the motor and control adjust the real-time frequency of the motor, so as to realize the control adjustment of the working frequency of the third conveying belt 8.

[0125] In addition, the forming section can further include a third feeding screw conveyor 9 for conveying the intermediate product to the forming equipment 10.

[0126] ​Specifically, the intermediate product output from the drying device 7 is transported to the molding device 10 through the third feeding screw conveyor 9 to form the fuel product. The outlet end of the third feeding screw conveyor 9 is matched with the feeding port of the molding device 10 to facilitate the smooth entry of the intermediate product into the molding device 10. In addition, the third feeding screw conveyor 9 can also mix and stir the intermediate product during the transportation of the intermediate product to the molding device 10 to improve the overall production efficiency of the intermediate product molding production line.

[0127] In the present disclosure, the third monitoring structure is used to monitor the working frequency (corresponding to f9 in the formula (1)) of the third feeding screw conveyor 9 and to transmit the working frequency of the third feeding screw conveyor 9 to the centralized control system 1. The third feeding screw conveyor 9 is signal-connected with the centralized control system 1 and is used to receive the control adjustment of the centralized control system 1 to adapt the working frequency of the third feeding screw conveyor 9 to the working frequency of the molding device 10. Figure 2

[0128] The power member of the third feeding screw conveyor 9 can be a motor, in which case the third monitoring structure is used to monitor the real-time frequency of the motor, and the centralized control system 1 is used to receive the real-time frequency of the motor and to control and adjust the real-time frequency of the motor, so as to realize the control and adjustment of the working frequency of the third feeding screw conveyor 9.

[0129] Of course, the present disclosure can also simultaneously provide the molding device 10, the third conveying belt 8 and the third feeding screw conveyor 9 on the molding section, in which case the intermediate product output from the drying device 7 enters the third conveying belt 8, and the third feeding screw conveyor 9 receives the intermediate product from the third conveying belt 8 and then transports the intermediate product to the molding device 10 to form the fuel product.

[0130] It should be noted that, in the molding section, the third monitoring structure can be used to monitor the working voltage and the working current on the molding device 10, the third conveying belt 8, the third feeding screw conveyor 9 and the corresponding motor, in addition to the working frequency, and to transmit the monitoring data to the centralized control system 1. The molding device 10, the third conveying belt 8, the third feeding screw conveyor 9 and the corresponding motor are signal-connected with the centralized control system 1 and are used to receive the control adjustment of the centralized control system 1, so as to realize the control and adjustment of the working voltage and the working current on the molding device 10, the third conveying belt 8, the third feeding screw conveyor 9 and the corresponding motor through the centralized control system 1, thereby ensuring the dynamic balance of the biomass fuel molding production line.

[0131] As shown in FIG. 1, the biomass fuel molding production line comprises a drying device 7, a molding device 10, a first feeding screw conveyor 2, a second feeding screw conveyor 5, a third feeding screw conveyor 9, a first conveying belt 3, a second conveying belt 6, a third conveying belt 8, a first monitoring structure, a second monitoring structure and a third monitoring structure. Figure 2 ​As shown, the working voltage of the third conveyor belt 8 is U8, the working current of the third conveyor belt 8 is I8, the working voltage of the third feeding screw conveyor 9 is U9, the working current of the third feeding screw conveyor 9 is I9, the working voltage of the molding device 10 is U10, and the working current of the molding device 10 is I10.

[0132] It should be further noted that the third monitoring structure in the present disclosure can include multiple monitors. For example, the present disclosure can be provided with one monitor on the molding device 10, the third conveyor belt 8, the third feeding screw conveyor 9, and the corresponding motor, respectively, for monitoring the working parameters (e.g., working frequency, working voltage, working current, temperature, pressure, etc.) of each device.

[0133] In the embodiment of the present disclosure, the biomass fuel molding production line can further include a packaging section located downstream of the molding section for receiving and packaging the fuel product. The packaging section includes a fourth monitoring structure for monitoring the working frequency (corresponding to f12 in the formula) of the packaging section. Figure 2 The fourth monitoring structure is in signal connection with the centralized control system 1, so as to enable the centralized control system 1 to receive and control the adjustment of the working frequency of the packaging section, so that the working frequency of the packaging section is adapted to the working frequencies of the crushing section, the drying section, and the molding section, to ensure the dynamic balance of the biomass fuel molding production line.

[0134] It should be noted that the fuel product has been formed in the molding section, but in order to facilitate the statistics of weight and storage and transportation, the present disclosure sets a packaging section on the biomass fuel molding production line to package the fuel product.

[0135] Specifically, the packaging section can include a packaging device 12 for packaging the fuel product. The fourth monitoring structure is used to monitor the working frequency of the packaging device 12 and to transmit the working frequency of the packaging device 12 to the centralized control system 1, so that the working frequency of the packaging device 12 receives the control of the centralized control system 1.

[0136] In the present disclosure, the motor can be used as the power element of the packaging device 12, at this time, the fourth monitoring structure is used to monitor the real-time frequency of the motor, and the centralized control system 1 is used to monitor the real-time frequency of the motor and to control and adjust the real-time frequency of the motor, so as to realize the control and adjustment of the working frequency of the packaging device 12.

[0137] Further, the packaging section can further include a fourth conveyor belt 11 for conveying the fuel product to the packaging device 12.

[0138] Specifically, the fuel product in the forming device 10 enters the packaging device 12 through the fourth conveying belt 11, and the fuel product is cooled and dried in the packaging section and is packed into sealed plastic bags by a packing machine.

[0139] In the present disclosure, the fourth monitoring structure is used to monitor the working frequency (corresponding to f11 in the fourth conveying belt 11) of the fourth conveying belt 11 and to transmit the working frequency of the fourth conveying belt 11 to the centralized control system 1. The fourth conveying belt 11 is signal-connected to the centralized control system 1 and is used to receive the control adjustment of the centralized control system 1 so as to adapt the working frequency to the working frequency of the packaging device 12. Figure 2

[0140] In the present disclosure, the fourth monitoring structure is used to monitor the working frequency (corresponding to f11 in the fourth conveying belt 11) of the fourth conveying belt 11 and to transmit the working frequency of the fourth conveying belt 11 to the centralized control system 1. The fourth conveying belt 11 is signal-connected to the centralized control system 1 and is used to receive the control adjustment of the centralized control system 1 so as to adapt the working frequency to the working frequency of the packaging device 12.

[0141] It is to be noted that, in the packaging section, the fourth monitoring structure can be used to monitor the working voltage and the working current of the packaging device 12, the fourth conveying belt 11 and the corresponding motor, in addition to the working frequency, and to transmit the monitoring data to the centralized control system 1. The packaging device 12, the fourth conveying belt 11 and the corresponding motor are signal-connected to the centralized control system 1 and are used to receive the control adjustment of the centralized control system 1, so as to realize the control adjustment of the working voltage and the working current of the packaging device 12, the fourth conveying belt 11 and the corresponding motor through the centralized control system 1, thereby ensuring the dynamic balance of the biomass fuel forming production line.

[0142] As shown in Figure 2 , the working voltage of the fourth conveying belt 11 is U11, the working current of the fourth conveying belt 11 is I11, the working voltage of the packaging device 12 is U12, and the working current of the packaging device 12 is I12.

[0143] It is to be further noted that the fourth monitoring structure in the present disclosure can include a plurality of monitors. For example, one monitor can be arranged on the packaging device 12, the fourth conveying belt 11 and the corresponding motor, respectively, to monitor the working parameters (such as the working frequency, the working voltage, the working current, etc.) of each device.

[0144] It should be understood that the motor in the present disclosure is a variable frequency motor.

[0145] The adjustment of the device control parameters in each section in the above depends mainly on the type of biomass raw material and the moisture content of the biomass raw material, and the corresponding monitoring parameters mainly include the voltage, the current, the temperature, the frequency, the humidity and the pressure.​

[0146] In actual production, after each device uploads the above key parameters to the centralized control system 1, the centralized control system 1 can automatically control each device, or manual control can be performed.

[0147] For example, after each device uploads the above key parameters to the centralized control system 1, the on-site operator can make a judgment in the first time in combination with the biomass raw material type and the biomass raw material moisture content information, and simultaneously issues adjustment instructions of the related device to the corresponding device control system.

[0148] For example, if the centralized control system 1 shows that the humidity of the biomass raw material in the drying section is too large, the supply amount of the drying heat source can be increased, or the rotation speed of the drying cylinder can be reduced to prolong the residence time of the material in the cylinder, so as to increase the removal of water in the biomass raw material. In order to ensure the continuity and economy of the entire production line, the frequency of the devices in other sections, the feeding and discharging frequency and other parameters can be adjusted at a corresponding speed.

[0149] But not limited to this, the present disclosure can also set corresponding preset monitoring parameter values for a plurality of biomass raw materials in the centralized control system 1, and automatically adjust and control the working frequency, working voltage, working current, temperature and other parameters of each device through the centralized control system 1, so as to restore or reach the corresponding preset monitoring parameter values.
