Description

Technical Field

[0001] This invention relates to the field of biomass liquid fuel processing technology, specifically to a multi-stage pulverizing device for biomass liquid fuel processing. Background Technology

[0002] Multi-stage crushing equipment for biomass liquid fuel processing is a specialized mechanical device used for multi-stage crushing of solid carbonaceous materials such as wood, straw, and oil shale. This type of equipment gradually crushes the raw materials to the particle size required for subsequent liquefaction processing through multiple stages such as coarse crushing, fine crushing, and grading and screening. Its core function is to increase the specific surface area of ​​biomass raw materials, thereby enhancing the rate and conversion rate of subsequent liquefaction reactions. At the same time, through precise control of multi-stage crushing, it avoids excessive energy consumption or insufficient crushing in a single crushing stage. It is one of the key pretreatment equipment in the industrial production of biomass liquid fuel.

[0003] In related technologies, multi-stage crushing equipment typically uses a rigid structure with a fixed angle and fixed trajectory to crush different biomass raw materials. However, this results in a single impact angle and crushing level for the materials, and large pieces of material often require multiple cycles of crushing to meet the required particle size, leading to low crushing efficiency. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a multi-stage crushing device for biomass liquid fuel processing, which solves the problem that crushing devices use fixed angles and fixed trajectories to crush different biomass raw materials, which easily leads to large pieces of material needing to be crushed multiple times, resulting in low crushing efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage crushing device for biomass liquid fuel processing, comprising a base, a crushing box detachably mounted on the upper surface of the base, a switching assembly provided on the inner wall of the crushing box, a motor fixedly connected to the inner wall of the crushing box, a rotating rod fixedly mounted on the output end of the motor, a sliding rod slidably connected to the inner wall of the rotating rod, a crushing rod rotatably connected to the outer wall of the sliding rod, the outer wall of the crushing rod rotatably connected to the inside of the crushing box, a guide block fixedly connected to the outer wall of the rotating rod, the outer wall of the guide block slidably connected to the top outer wall of the crushing rod, and the connection between the crushing rod and the sliding rod slidably connected to the inner wall of the rotating rod.

The motor then drives the rotating rod and sliding rod to rotate synchronously. The crushing rod opens due to centrifugal force, and a switching component locks it in place, ensuring stable crushing. When the sliding rod drives the rotating rod upwards, the connection between the crushing rod and the sliding rod slides against the inner wall of the rotating rod, allowing the crushing rod to fold quickly. When the sliding rod drives the rotating rod downwards, the sliding rod slides against the inclined outer wall of the guide block, allowing the crushing rod to unfold. Once the crushing rod reaches the desired position, the sliding rod engages, quickly fixing the crushing rod in place.

[0009] Preferably, the switching component includes a compression box, the outer wall of which is detachably mounted on the inner wall of the crushing chamber, and a limit ring is fixedly connected to the inner top wall of the crushing chamber, the inner wall of which is slidably connected to the outer wall of the pull block.

[0010] Preferably, a sliding plate is slidably connected to the lower surface of the limiting ring, the outer wall of the sliding plate is slidably connected to the inner wall of the crushing box, and a threaded groove is provided on the inner wall of the crushing box, the inner wall of the threaded groove being slidably connected to the outer wall of the sliding plate.

[0011] Preferably, the slider near the center of the limiting ring is made of iron material, the upper surface of the slider is slidably connected to the lower surface of the pull block, the outer wall of the slider is slidably connected to the outer wall of the rotating rod, the outer wall of the rotating rod is fixedly connected to a guide strip, and the outer wall of the guide strip is slidably connected to the inner wall of the slider.

[0012] Preferably, a cleaning rod is fixedly connected to the lower surface of the grinding block, and a screening screen is rotatably connected to the outer wall of the cleaning rod. The outer wall of the screening screen is fixedly connected to the inner wall of the crushing box, and a discharge port is opened on the inner wall of the crushing box near the upper side of the screening screen.

[0013] Preferably, a cleaning rod is fixedly connected to the lower surface of the grinding block, and a screening screen is rotatably connected to the outer wall of the cleaning rod. The outer wall of the screening screen is fixedly connected to the inner wall of the crushing box, and a discharge port is opened on the inner wall of the crushing box near the upper side of the screening screen.

[0014] Preferably, a guide tube is fixedly connected to the inner wall of the discharge port, the outer wall of the guide tube is fixedly connected to the inner wall of the crushing box, a second motor is fixedly connected to the upper surface of the base, an auger blade is fixedly provided at the output end of the second motor, and the outer wall of the auger blade is rotatably connected to the inner wall of the guide tube.

[0015] Preferably, a guide pipe is fixedly connected to the inner wall of the crushing box near the lower side of the screening screen, a fan is fixedly connected to the inner wall of the guide pipe, the outer wall of the fan is fixedly connected to the inner wall of the crushing box, and a collection box is detachably installed on the inner wall of the base.

[0016] Working principle: Oil shale, oil sand, or non-melting solid carbonaceous materials or similar substances are poured into the crushing chamber. The motor then starts, driving the rotating rod to rotate. This rotating rod, in conjunction with a switching component, drives the sliding rod to rotate synchronously. The rotating rod drives the sliding rod, causing the crushing rod to open due to centrifugal force. The switching component locks the crushing rod, ensuring stable crushing. When the sliding rod drives the rotating rod upwards, the connection between the crushing rod and the sliding rod slides against the inner wall of the rotating rod, allowing the crushing rod to fold quickly. When the sliding rod drives the rotating rod downwards, the sliding rod causes the crushing rod to slide against the inclined outer wall of the guide block, unfolding the crushing rod. Once the crushing rod reaches the desired position, the sliding rod abuts against it, quickly fixing the crushing rod in place.

[0017] This invention provides a multi-stage pulverizing device for processing biomass liquid fuel. It has the following beneficial effects: 1. This invention involves pouring materials into the crushing chamber, at which point the motor is started, causing the rotating rod and sliding rod to rotate synchronously. This causes the sliding rod to drive the crushing rod to rotate synchronously, thereby allowing the rotating rod to rotate and unfold the crushing rod. This enables the crushing rod to crush quickly while simultaneously achieving the effect of crushing at different angles by folding.

[0018] 2. This invention enables the fixed plate and the pull block to slide synchronously by activating the electric push rod, which in turn causes the pull block to pull the mounting column and the slide rod to slide synchronously. The slide rod then causes the docking block to detach from or dock with the grinding block, allowing for quick replacement of the hollow box or compression box. It also drives the grinding block to rotate synchronously for crushing and grinding, achieving a multi-stage crushing effect.

[0019] 3. When the present invention uses a sliding rod to pull the crushing rod for recycling, the pulling block will detach from the sliding plate, allowing the sliding plate to slide to the inner wall of the threaded groove and connect with the guide bar. This allows the rotating rod to rotate while the sliding plate slides up and down, enabling the sliding plate to quickly compress and collect materials.

[0020] 4. This invention uses the grinding block to drive the cleaning rod to rotate, allowing the cleaning rod to push the material into the inner wall of the guide tube, and the motor two, together with the auger blade, to transport the material back into the crushing box, thus achieving the effect of secondary multi-stage crushing and grinding.

Detailed Implementation

[0023] The technical solution of the present invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] Example 1: Please see the appendix Figure 1 Appendix Figure 3 and attached Figure 5 This invention provides a multi-stage crushing device for processing biomass liquid fuel, including a base 1. A crushing box 2 is detachably installed on the upper surface of the base 1. A switching component 3 is provided on the inner wall of the crushing box 2. A motor 4 is fixedly connected to the inner wall of the crushing box 2. A rotating rod 5 is fixedly installed at the output end of the motor 4. A sliding rod 6 is slidably connected to the inner wall of the rotating rod 5. A crushing rod 7 is rotatably connected to the outer wall of the sliding rod 6. The outer wall of the crushing rod 7 is rotatably connected to the inside of the crushing box 2. A guide block 8 is fixedly connected to the outer wall of the rotating rod 5. The outer wall of the guide block 8 is slidably connected to the top outer wall of the crushing rod 7. The connection between the crushing rod 7 and the sliding rod 6 is slidably connected to the inner wall of the rotating rod 5.

[0025] Specifically, by installing the crushing box 2 onto the upper surface of the base 1 for easy material discharge, the motor 4 is started to drive the rotating rod 5 to rotate. The rotating rod 5, in conjunction with the switching component 3, drives the sliding rod 6 to rotate synchronously. The rotation of the sliding rod 6 by the rotating rod 5 causes the crushing rod 7 to open due to centrifugal force, and the switching component 3 locks the crushing rod 7 in place. At this time, oil shale, oil sand, or non-melting solid carbonaceous materials or similar materials are poured into the two sets of feed inlets on the front side of the crushing box 2, which allows the crushing rod 7 to achieve stable crushing and stirring. When the sliding rod 6 drives the rotating rod 5 to slide upward, the connection between the crushing rod 7 and the sliding rod 6 will slide on the inner wall of the rotating rod 5, allowing the crushing rod 7 to achieve a quick folding effect. When the sliding rod 6 drives the rotating rod 5 to slide downward, the sliding rod 6 will drive the crushing rod 7 to slide on the inclined outer wall of the guide block 8, thereby allowing the crushing rod 7 to unfold. After the crushing rod 7 slides to the appropriate position, the sliding rod 6 will abut against the crushing rod 7 to achieve a quick fixation effect.

[0026] Example 2: Please see the appendix Figure 2 Appendix Figure 3 and attached Figure 4 The switching component 3 includes a hollow box 31. The outer wall of the hollow box 31 is detachably installed on the inner wall of the crushing box 2. An electric push rod 32 is fixedly connected to the upper surface of the crushing box 2. A fixed plate 33 is fixedly installed at the output end of the electric push rod 32. The outer wall of the fixed plate 33 is slidably connected to the inner wall of the pull block 34. The outer wall of the pull block 34 is slidably connected to the inner wall of the crushing box 2. An installation column 35 is detachably installed on the inner wall of the pull block 34. The outer wall of the installation column 35 is snapped into the inner wall of the slide rod 6. The outer wall of the installation column 35 is slidably connected to the inner wall of the rotating rod 5. The outer wall of the rotating rod 5 is rotatably connected to the inner wall of the pull block 34.

[0027] Specifically, when the hollow box 31 is installed on the inner wall of the grinding chamber 2 for grinding, the motor 4 drives the rotating rod 5 to rotate on the inner wall of the pull block 34, causing the pull block 34 to drive the mounting column 35 to rotate synchronously. The mounting column 35 is installed on the inner wall of the slide rod 6, which allows the motor 4 to drive the rotating rod 5 and the slide rod 6 to rotate synchronously. By rotating the pull block 34 on the outer wall of the fixed plate 33 and the inner wall of the grinding chamber 2, the pull block 34 can achieve the effect of preventing deviation. When the electric push rod 32 is activated to push and pull the fixed plate 33 to slide, it will drive the pull block 34 to slide synchronously. The mounting column 35 slides on the inner wall of the rotating rod 5 and pushes and pulls the slide rod 6, which allows the slide rod 6 to stably release and retract the grinding rod 7.

[0028] Example 3: Please see the appendix Figure 3 and attached Figure 6 The switching component 3 includes a compression box 36, the outer wall of which is detachably installed on the inner wall of the crushing box 2. A limit ring 37 is fixedly connected to the inner top wall of the crushing box 2. The inner wall of the limit ring 37 is slidably connected to the outer wall of the pull block 34. A sliding plate 38 is slidably connected to the lower surface of the limit ring 37. The outer wall of the sliding plate 38 is slidably connected to the inner wall of the crushing box 2. A threaded groove 10 is provided on the inner wall of the crushing box 2. The inner wall of the threaded groove 10 is slidably connected to the outer wall of the sliding plate 38. The center of the sliding plate 38 near the limit ring 37 is made of iron. The upper surface of the sliding plate 38 is slidably connected to the lower surface of the pull block 34. The outer wall of the sliding plate 38 is slidably connected to the outer wall of the rotating rod 5. A guide strip 39 is fixedly connected to the outer wall of the rotating rod 5. The outer wall of the guide strip 39 is slidably connected to the inner wall of the sliding plate 38.

[0029] Specifically, when it is necessary to quickly recover oil shale, oil sand, or non-melting solid carbonaceous materials or similar substances mixed in the air inside the crushing chamber 2, the compression box 36 is installed on the inner wall of the crushing chamber 2. At this time, the electric push rod 32 is activated to push the fixed plate 33 and the pull block 34 to slide. Since the lower surface of the pull block 34 is made of magnetic blocks, the lower surface of the pull block 34 will attract the center of the sliding plate 38 and slide synchronously. The sliding plate 38 slides on the inner wall of the crushing chamber 2, which can achieve a stable sliding effect. When the upper surface of the sliding plate 38 abuts against the lower surface of the limiting ring 37, the electric push rod 32 is activated again to push the pull block 34 to slide, so that the sliding plate 38 disengages. The slider 34 is pulled away from the guide bar 39 and falls into the threaded groove 10. At the same time, the inner wall of the slider 38 will hold the guide bar 39. When the rotating rod 5 and the sliding rod 6 rotate, the guide bar 39 will rotate synchronously. The guide bar 39 will drive the slider 38 to slide in the threaded groove 10, so that the slider 38 can quickly collect the residue to the inner wall of the compression box 36 and squeeze it to form clumps. This achieves the effect of convenient recycling and cleaning the inner wall of the crushing box 2. When the rotating rod 5 and the sliding rod 6 reverse, the slider 38 will be reset. At this time, the electric push rod 32 will be activated to drive the slider 34 to reset, so that the slider 34 can re-adsorb the slider 38, which can achieve the effect of the slider 38 quickly detaching from the guide bar 39.

[0030] Example 4: Please see the appendix Figure 1 Appendix Figure 2 Appendix Figure 7 and attached Figure 8 A connecting block 9 is fixedly connected to the lower surface of the slide bar 6. A grinding block 11 is snapped onto the outer wall of the connecting block 9. The outer wall of the grinding block 11 is rotatably connected to the inner wall of the crushing box 2. A fixing ring 12 is rotatably connected to the inner wall of the grinding block 11. The outer wall of the fixing ring 12 is fixedly connected to the inner wall of the crushing box 2. A cleaning rod 13 is fixedly connected to the lower surface of the grinding block 11. A screening screen 14 is rotatably connected to the outer wall of the cleaning rod 13. The outer wall of the screening screen 14 is fixedly connected to the inner wall of the crushing box 2. A discharge port 15 is opened on the inner wall of the crushing box 2 near the upper side of the screening screen 14. A guide tube 21 is fixedly connected to the inner wall of the feed inlet 15. The outer wall of the guide tube 21 is fixedly connected to the inner wall of the crushing box 2. A motor 2 19 is fixedly connected to the upper surface of the base 1. An auger blade 20 is fixedly installed at the output end of the motor 2 19. The outer wall of the auger blade 20 is rotatably connected to the inner wall of the guide tube 21. A flow guide tube 17 is fixedly connected to the inner wall of the crushing box 2 near the lower side of the screening screen 14. A blower 16 is fixedly connected to the inner wall of the flow guide tube 17. The outer wall of the blower 16 is fixedly connected to the inner wall of the crushing box 2. A collection box 18 is detachably installed on the inner wall of the base 1.

[0031] Specifically, when the slide bar 6 slides and causes the crushing bar 7 to open, the slide bar 6 will cause the connecting block 9 to slide synchronously and lock the grinding block 11, allowing the slide bar 6 to drive the grinding block 11 to rotate synchronously, achieving the effect of crushing and grinding at the same time. The grinding block 11 rotates on the outer wall of the fixing ring 12, while the fixing ring 12 is fixed to the inner wall of the crushing box 2, ensuring stable rotation of the grinding block 11. The ground material will pass through the sieve 14 into the collection box 18, where it will be sieved and filtered. The sieved material will then enter the collection box 18, achieving a rapid collection effect. When there is material that cannot be sieved... When the material is being processed, the grinding block 11 will drive the cleaning rod 13 to rotate on the upper surface of the screening screen 14, so that the cleaning rod 13 cleans the material into the discharge port 15, which can facilitate the discharge of the material and clean the screening screen 14 at the same time. The material enters the guide tube 21 through the discharge port 15. At this time, the motor 19 is started to drive the auger blade 20 to rotate, which can stably discharge the material into the crushing box 2 for secondary crushing and grinding. After the material enters the collection box 18, the fan 16 is started to allow the guide tube 17 to re-enter the floating material in the collection box 18 into the crushing box 2, which can achieve the effect of easy compaction and removal.

[0032] The workflow involves pouring the material into the crushing chamber 2. At this time, the motor 4 is started, driving the rotating rod 5 and the sliding rod 6 to rotate synchronously. The sliding rod 6 drives the docking block 9 to rotate, which in turn drives the grinding block 11 to rotate, achieving a stable crushing and grinding effect. When the material falls onto the upper surface of the screening screen 14, the crushed and ground material will enter the collection box 18. For the material that the screening screen 14 cannot screen, the grinding block 11, together with the cleaning rod 13, will push the material into the guide tube 21, and the motor 19 will drive the auger blade 20 to transport the material back into the crushing chamber 2 for secondary crushing and grinding.

[0033] After the material inside the crushing box 2 has been processed, the hollow box 31 is removed and replaced with the compression box 36. At this time, the blower 16 is started in conjunction with the guide pipe 17 to discharge the floating material inside the collection box 18 into the crushing box 2. Then, the electric push rod 32 is started to push the fixed plate 33 and the pull block 34 to slide synchronously, so that the pull block 34 pulls the mounting column 35 and the slide rod 6 to slide synchronously. This allows the slide rod 6 to work with the rotating rod 5 to achieve the effect of quickly folding the crushing rod 7. When the pull block 34 slides to the appropriate position, it will stop against the limit ring 37. At this time, the electric push rod 32 is started again, which allows the sliding plate 38 to disengage from the pull block 34, so that the sliding plate 38 slides on the inner wall of the threaded groove 10 and the outer wall of the guide strip 39. This allows the slide rod 6 to drive the sliding plate 38 to rotate synchronously and slide up and down. By sliding the sliding plate 38 on the inner wall of the threaded groove 10, the threaded groove 10 cleans the inner wall of the crushing box 2, and at the same time, the compression box 36 compacts the floating material inside the crushing box 2.
