[0053] See Figure 1-3 As shown, this embodiment provides an automatic extraction and energy conversion device for biomass cellulose based on forestry residues, comprising: a pretreatment chamber 100 and an enzymatic hydrolysis chamber 200; the pretreatment chamber 100 comprises: a feed assembly located at the top of the pretreatment chamber 100; a crushing assembly and a filtering assembly, wherein the crushing assembly is located below the feed assembly, the filtering assembly is located below the crushing assembly, and one side of the filtering assembly is connected to the inner wall of the pretreatment chamber 100, and the other side extends out of the pretreatment chamber 100; a liquid outlet assembly is located below the filtering assembly, one side of the liquid outlet assembly extends out of the pretreatment chamber 100, and the other side of the liquid outlet assembly is connected to the inner wall of the pretreatment chamber 100;

[0054] The enzymatic hydrolysis chamber 200 includes: a first stirring component 210, which is arranged at the top of the enzymatic hydrolysis chamber 200; two second stirring components 220, and the two second stirring components 220 are symmetrically arranged at the bottom of the enzymatic hydrolysis chamber 200; a pH adjustment component, which is located on the outer wall of the enzymatic hydrolysis chamber 200, and the pH adjustment component extends into the interior of the enzymatic hydrolysis chamber 200 through the liquid inlet pipe 150; and a plurality of temperature sensors, and the plurality of temperature sensors are located inside the enzymatic hydrolysis chamber 200.

[0055] It is understandable that the present embodiment includes a pretreatment chamber 100 and an enzymolysis chamber 200, the pretreatment chamber 100 is used to process raw materials, and the enzymolysis chamber 200 is used to perform enzymolysis reaction under specific pH and temperature conditions to extract biomass cellulose. Through the precise control of the first stirring component 210 and the second stirring component 220 by the controller 240, it can be ensured that the raw materials are fully mixed in the enzymolysis chamber 200, thereby improving the extraction efficiency of cellulose. At the same time, the pH adjustment component can automatically adjust the pH value in the enzymolysis chamber 200 according to the feedback information of the pH sensor, ensuring that the enzymolysis reaction is carried out in the optimal acid-base environment. The setting of the temperature sensor can monitor the temperature in the enzymolysis chamber 200 in real time, ensure that the reaction is carried out within a suitable temperature range, and further improve the efficiency of energy conversion and the extraction rate of biomass cellulose.

[0056] It is understandable that the pretreatment chamber 100 and the enzymatic hydrolysis chamber 200 are preferably made of stainless steel or high-performance materials such as polytetrafluoroethylene (PTFE) and glass fiber reinforced plastic (FRP); the stirring component is preferably made of titanium alloy, which has excellent corrosion resistance, especially in strong acid and strong alkali environments; the filtering component is preferably made of stainless steel wire mesh or composite ceramic material, which can provide higher wear resistance and corrosion resistance, and is easy to clean and maintain.

[0057] Specifically, the feeding assembly includes: a feed hopper 111, located at the top of the pretreatment bin 100; a screw conveyor 112, arranged horizontally at the bottom of the feed hopper 111, one end of the screw conveyor 112 is connected to the feed hopper 111, and the other end of the screw conveyor 112 extends to the top of the crushing assembly; a first motor 113, arranged on the side of the feed hopper 111 away from the crushing assembly, and the output end of the first motor 113 is connected to the screw conveyor 112.

[0058] As will be understood, the feed hopper 111 is used to temporarily store forestry residues, while the auger 112 is used to transport the residues from the feed hopper 111 to the pulverization assembly for pulverization. A first motor 113 powers the auger 112, ensuring continuous and stable material delivery to the pulverization assembly. This not only improves material processing efficiency but also ensures the continuity and automation of the entire extraction process.

[0059] Specifically, it is characterized in that the crushing assembly includes: a crushing chamber 121, located in the middle of the pretreatment bin 100, a feed port is provided at the top of the crushing chamber 121, and the output end of the screw conveyor 112 extends into the feed port; a crushing roller 122, located inside the crushing chamber 121.

[0060] It is understood that the crushing roller 122 crushes the forestry residues entering the crushing chamber 121 by rotating at high speed to achieve a desired particle size.

[0061] Specifically, it is characterized in that the filtering component includes: a screen 131, which is located at the bottom of the crushing roller 122, and the screen 131 is set at an angle, the high end of the screen 131 is located on the side away from the screw conveyor 112, and a first separation port is set at the low end of the screen 131.

[0062] It is understood that the function of screen 131 is to separate the pulverized material and ensure that the cellulose suspension is transported to the liquid outlet assembly. The inclined design of screen 131 facilitates the natural flow of the material. At the same time, the configuration of the first separation port allows large solid residues to be discharged smoothly, while the cellulose suspension continues downward into the liquid outlet assembly.

[0063] Specifically, it is characterized in that the liquid outlet component includes: a liquid outlet plate 141, which is located at the bottom of the screen 131, and the liquid outlet plate 141 is arranged at an angle, the high end of the liquid outlet plate 141 is located on the side close to the screw conveyor 112, and a second separation port is provided at the lower end of the liquid outlet plate 141; a liquid collecting tank 142, which is located at the bottom of the liquid outlet plate 141, the liquid collecting tank 142 is connected to the outer wall of the pretreatment chamber 100, and a liquid outlet is provided at the bottom of the liquid collecting tank 142.

[0064] It is understood that the function of the liquid outlet plate 141 is to guide the cellulose suspension to the liquid collection tank 142, while the second separation port ensures that solid residues do not enter the liquid collection tank 142. The cellulose suspension collected in the liquid collection tank 142 is discharged through the liquid outlet port for subsequent energy conversion. This not only improves the separation efficiency of the materials but also ensures a clean and efficient extraction process. This device can achieve efficient utilization of forestry residues and convert waste into valuable biomass energy, which is both environmentally friendly and economical.

[0065] Specifically, it is characterized in that the top of the enzymatic hydrolysis chamber 200 is connected to the liquid outlet through a liquid inlet pipe 150, and a liquid inlet valve 151 is provided at one end of the liquid inlet pipe 150 close to the enzymatic hydrolysis chamber 200.

[0066] It is understood that the combination of the liquid inlet pipe 150 and the liquid inlet valve 151 enables the cellulose suspension extracted from the pretreatment chamber 100 to be precisely controlled and delivered to the enzymatic hydrolysis chamber 200. The setting of the liquid inlet valve 151 allows the operator to adjust the flow rate of the cellulose suspension according to the actual needs of the enzymatic hydrolysis reaction, ensuring that an appropriate liquid cellulose concentration is maintained in the enzymatic hydrolysis chamber 200, thereby optimizing the enzymatic hydrolysis efficiency.

[0067] Specifically, it is characterized in that the first stirring component 210 includes: a first stirring shaft 211, which is arranged at the top of the enzymatic hydrolysis chamber 200 in a vertical direction; a first stirring blade 212, which has a plurality of first stirring blades 212, which are staggered on the first stirring shaft 211 in a direction perpendicular to the axial direction of the first stirring shaft 211; a second motor 213, which is arranged on the inner bottom wall of the enzymatic hydrolysis chamber 200, and the output end of the second motor 213 is connected to the first stirring shaft 211.

[0068] It is understood that the first stirring shaft 211 is rotated by the second motor 213, thereby achieving sufficient stirring of the liquid cellulose in the enzymatic hydrolysis chamber 200. The design of the first stirring blade 212 makes stirring more uniform, which helps to improve the efficiency of the enzymatic hydrolysis reaction and the extraction rate of biomass cellulose. In addition, the provision of the first stirring assembly 210 can also prevent possible material deposition in the enzymatic hydrolysis chamber 200, ensuring the uniformity of the reaction process.

[0069] Specifically, the second stirring assembly 220 includes: a second stirring shaft 221, which is horizontally arranged at the top of the enzymatic hydrolysis chamber 200; a second stirring blade 222, which has a plurality of second stirring blades 222, which are staggered on the second stirring shaft 221 along a direction perpendicular to the axial direction of the second stirring shaft 221; a third motor 223, which is arranged on the inner side wall of the enzymatic hydrolysis chamber 200, and the output end of the third motor 223 is connected to the second stirring shaft 221.

[0070] It is understood that the second stirring shaft 221 is rotated by the drive of the third motor 223 and works in conjunction with the first stirring assembly 210 to further ensure that the liquid cellulose in the enzymatic hydrolysis chamber 200 is evenly mixed. The design of the second stirring blade 222 also helps to improve the stirring efficiency and prevent the material from depositing during the enzymatic hydrolysis process, thereby maintaining the uniformity and continuity of the enzymatic hydrolysis reaction. Through the configuration of this dual stirring assembly, it is possible to achieve fine control of the enzymatic hydrolysis process and ensure that the extraction efficiency of biomass cellulose is maximized.

[0071] Specifically, it is characterized in that the pH adjustment component includes: an acidic storage tank 231, located on the outer wall of the enzymatic hydrolysis chamber 200, the acidic storage tank 231 is connected to the interior of the enzymatic hydrolysis chamber 200 through a first delivery pipe, and a first valve is provided at one end of the first delivery pipe close to the enzymatic hydrolysis chamber 200; an alkaline storage tank 232, located on the outer wall of the enzymatic hydrolysis chamber 200, the alkaline storage tank 232 is connected to the interior of the enzymatic hydrolysis chamber 200 through a second delivery pipe, and a second valve is provided at one end of the second delivery pipe close to the enzymatic hydrolysis chamber 200; a pH sensor is arranged inside the enzymatic hydrolysis chamber 200.

[0072] It is understandable that the pH sensor is used to monitor the pH value in the enzymatic hydrolysis chamber 200 in real time to ensure that the enzymatic hydrolysis process is carried out in a suitable acid-base environment. When it is detected that the pH value deviates from the preset range, the system will automatically adjust the opening and closing of the first valve or the second valve to control the amount of acidic or alkaline substance added to achieve the purpose of quickly adjusting the pH value. This automated pH adjustment mechanism not only improves the stability and reliability of the enzymatic hydrolysis process, but also reduces manual intervention, further improving the efficiency and automation level of the entire biomass energy extraction process.

[0073] Specifically, an enzymolysis outlet 250 is further provided at the bottom of the enzymolysis chamber 200 .

[0074] Specifically, the automatic extraction and energy conversion device of biomass cellulose based on forestry residues also includes: a controller 240, located on the outer wall of the enzymatic hydrolysis chamber 200, and the controller 240 is connected to the first stirring component 210, the second stirring component 220 and the pH adjustment component.

[0075] It is understood that controller 240, as the intelligent core of the entire device, is responsible for receiving data from various components and analyzing and processing this data according to pre-set programs and algorithms. Controller 240 is able to monitor and adjust the operating status of first stirring component 210 and second stirring component 220 in real time to ensure uniformity and efficiency of stirring. Simultaneously, controller 240 works closely with the pH adjustment component, automatically adjusting the addition of acid and base substances based on feedback from the pH sensor to maintain the pH value of the enzymatic hydrolysis process within the optimal range.

[0076] In summary, the automated biocellulose extraction and energy conversion device based on forestry residues provided in this embodiment enables efficient utilization of forestry residues, converting waste into valuable biomass energy, which is both environmentally friendly and economical. Through a precisely controlled automated system, continuous biocellulose extraction and energy conversion can be achieved, significantly improving the production efficiency and quality of biomass energy. Furthermore, the design of this device also takes into account ease of operation and convenient maintenance, making the biomass energy extraction process more efficient, stable, and sustainable.
