Description

Technical Field

[0001] This utility model relates to the field of papermaking technology, and in particular to a wood chip hydrolysis pulping device. Background Technology

[0002] Wood chip hydrolysis pulping units are integrated equipment systems used to convert wood raw materials into usable fibers or sugars, and are widely used in pulp and paper making, biomass energy, and biochemical industries. Their core function is to transform wood chips from solid raw materials into usable products through the synergistic action of pretreatment, hydrolysis reaction, and pulp separation.

[0003] Existing wood chip hydrolysis devices typically involve directly immersing wood chips into a tank containing chemicals. While the surface of the wood chips can quickly come into contact with the hydrolysate, the central region suffers from a long chemical penetration path and high diffusion resistance, making it difficult to quickly absorb the chemical reagents required for the reaction. This results in an unbalanced state, requiring a longer overall reaction time and significantly reducing production efficiency. Utility Model Content

[0005] This utility model is achieved by the following technical solution: a wood chip hydrolysis pulping device, including a mixing mechanism, an auxiliary mechanism is provided on the left side of the mixing mechanism, and a rolling mechanism is provided at the bottom of the auxiliary mechanism;

[0006] The mixing mechanism includes a heating tank with an inlet pipe connected inside. A support foot is fixedly connected to the outer wall of the heating tank. A support plate is fixedly connected to the top of the heating tank. A motor is fixedly connected to the bottom of the support plate. A rotating rod is fixedly connected to the output end of the motor. A support plate is rotatably connected to the outer wall of the end of the rotating rod away from the motor. The support plate is fixedly connected to the inner wall of the mixing mechanism. A crushing rod is fixedly connected to the outer wall of the rotating rod. A stirring plate is fixedly connected to the outer wall of the rotating rod.

[0007] Through the above technical solution, the support feet support the heating tank. At this time, the wood chips enter from the top of the heating tank, and the inlet pipe injects hydrolysate into the heating tank. The support plate supports the motor, and the motor drives the rotating rod to rotate. The rotating rod drives the crushing rod to further crush the wood chips. The stirring plate ensures that the wood chips and hydrolysate are fully mixed. The crushing rod reduces the volume of the wood chips by crushing them, which helps to ensure that the medicine is quickly absorbed in the central area of ​​the wood chips, improves the uniformity of hydrolysis, and enhances the mixing effect of wood chips and hydrolysate. Combined with the precise temperature control of the heating tank, the reaction time is shortened and the production efficiency is improved.

[0008] As a further improvement to the above solution, the auxiliary mechanism includes an electromagnetic valve, which is connected to the bottom of the heating tank. The end of the electromagnetic valve away from the heating tank is connected to a feed pipe, and the end of the feed pipe away from the electromagnetic valve is connected to a pump body.

[0009] As a further improvement to the above solution, a support foot is fixedly connected to the outer wall of the pump body, a pipe is connected to the end of the pump body away from the feed pipe, and a pulper is connected to the end of the pipe away from the pump body.

[0010] As a further improvement to the above solution, the outer wall of the pulper is fixedly connected with a second support foot, the bottom of the pulper is connected to a first pipe, the end of the first pipe away from the pulper is connected to a first solenoid valve, and the end of the first solenoid valve away from the first pipe is connected to a discharge pipe.

[0012] As a further improvement to the above solution, a flow groove is provided inside the conveyor belt, and a rolling roller is provided at the top of the flow groove. A rotating rod is fixedly connected inside the rolling roller, and a motor is fixedly connected to the outer end of the rotating rod. A support plate is fixedly connected to the outer wall of the motor.

[0013] As a further improvement to the above solution, a bracket is fixedly connected to the outer wall of the support plate three, the bracket is fixedly connected to the top of the fixed plate, a flat plate is fixedly connected to the outer wall of the bracket, an auxiliary roller is contacted and arranged on the inner wall of the conveyor belt, a rotating rod three is fixedly connected inside the auxiliary roller, and a liquid collection frame is rotatably connected to the outer wall of the rotating rod three.

[0014] Through the above technical solution, motor two drives the crushing roller to rotate via rotating rod two. Since rotating rod two rotates inside the support, the support supports rotating rod two. At the same time, a flat plate is fixed on the outer wall of the support. The flat plate scrapes the material and makes the material evenly spread on the surface of the conveyor belt. The crushing roller rotates on the surface of the conveyor belt, and the auxiliary roller rotates on the inner wall of the conveyor belt. The auxiliary roller rotates inside the liquid collection frame via rotating rod three. Thus, the material is crushed by bidirectional extrusion of the auxiliary roller and the crushing roller, thereby squeezing the wood pulp out of the material more efficiently, improving the initial separation efficiency of wood pulp, and improving the product quality of subsequent hydrolysis and pulping. At the same time, the pulp is collected by the liquid collection frame.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] This invention uses support feet to support the heating tank. Wood chips enter from the top of the heating tank, and the inlet pipe injects hydrolysate into the tank. The support plate supports the motor, which drives the rotating rod to rotate. The rotating rod drives the crushing rod to further crush the wood chips, while the stirring plate ensures thorough mixing of the wood chips and hydrolysate. The crushing rod reduces the volume of the wood chips, allowing for rapid absorption of the drug in the center of the wood chips and improving the uniformity of hydrolysis. The stirring plate enhances the mixing effect between the wood chips and hydrolysate. Combined with precise temperature control in the heating tank, this shortens the reaction time and improves production efficiency.

[0017] This invention utilizes a motor to drive a grinding roller via a rotating rod. The rotating rod rotates inside a support frame, which supports it. A flat plate is fixed to the outer wall of the support frame to level the material, ensuring it is evenly spread on the conveyor belt surface. The grinding roller rotates on the conveyor belt surface, while an auxiliary roller rotates on the inner wall of the conveyor belt. The auxiliary roller rotates inside a collection frame via a rotating rod. This bidirectional compression by the auxiliary roller and the grinding roller effectively crushes the material, efficiently extracting wood pulp, improving initial pulp separation efficiency, and enhancing the quality of subsequent hydrolysis and pulping products. The pulp is then collected by the collection frame. Attached Figure Description

[0031] The pulper 206 is fixedly connected to the outer wall of the support foot 207. The bottom of the pulper 206 is connected to the pipe 208. The end of the pipe 208 away from the pulper 206 is connected to the solenoid valve 209. The end of the solenoid valve 209 away from the pipe 208 is connected to the discharge pipe 210.

[0032] The rolling mechanism 3 includes a fixed plate 301, a support plate 302 fixedly connected to the outer wall of the fixed plate 301, a motor 303 fixedly connected to the top of the support plate 302, a rotating rod 304 fixedly connected to the output end of the motor 303, the rotating rod 304 being rotatably connected inside the fixed plate 301, and a conveyor belt 305 being rotatably connected to the outer wall of the rotating rod 304.

[0033] The conveyor belt 305 has a flow groove 306 inside, and a rolling roller 307 is arranged in contact with the top of the flow groove 306.

[0035] The implementation principle of an automated meat grinder in this embodiment is as follows: Support feet 103 support the heating tank 101. Wood chips enter from the top of the heating tank 101. Hydrolysate is injected into the heating tank 101 through the inlet pipe 102. Support plate 104 supports the motor 105. The motor 105 drives the rotating rod 106 to rotate. The rotating rod 106 drives the crushing rod 108 to further crush the wood chips. The stirring plate 109 ensures thorough mixing of the wood chips and hydrolysate. The crushing rod 108 reduces the volume of the wood chips, allowing for rapid absorption of the medicine in the central area of ​​the wood chips and improving the uniformity of hydrolysis. The stirring plate 109 enhances the interaction between the wood chips and the hydrolysate. The mixing effect, combined with precise temperature control in the heating tank 101, shortens the reaction time and improves production efficiency. After mixing, the solenoid valve 201 opens, and the material is conveyed from the feed pipe 202 to the pump body 203 and then to the pulper 206 via the pipe 205. Support leg 1 204 supports the pump body 203. The pulper 206 further crushes the material, and support leg 207 supports the pulper 206. The crushed material is discharged from the discharge pipe 210 via pipe 1 208 and solenoid valve 1 209. Solenoid valve 1 209 controls the discharge speed to ensure uniform feeding. Support plate 2 302 supports motor 1 303. Machine 303 drives the conveyor belt 305 to rotate via rotating rod 304. Since rotating rod 304 rotates inside fixed plate 301, which supports the entire conveying device, a flow channel 306 is formed inside the conveyor belt 305. When the pulverized material falls evenly onto the top of the conveyor belt 305, the liquid flows into the collection frame 315 along the flow channel 306. Simultaneously, support plate 310 supports motor 309, which drives the crushing roller 307 to rotate via rotating rod 308. Since rotating rod 308 rotates inside bracket 311, bracket 311 supports the rotating rod 307. Support 308 is provided, and a flat plate 312 is fixed to the outer wall of the support 311. The flat plate 312 scrapes the material to make it evenly spread on the surface of the conveyor belt 305. The crushing roller 307 rotates on the surface of the conveyor belt 305, and the auxiliary roller 313 rotates on the inner wall of the conveyor belt 305. The auxiliary roller 313 rotates inside the liquid collection frame 315 through the rotating rod 314. Thus, the material is crushed by bidirectional extrusion of the auxiliary roller 313 and the crushing roller 307, thereby squeezing the wood pulp out of the material more efficiently, improving the initial separation efficiency of wood pulp, and improving the product quality of subsequent hydrolysis and pulping. At the same time, it is collected by the liquid collection frame 315.
