Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of biomass energy utilization, in particular to a biomass straw superfine crushing equipment and method. BACKGROUND

[0002] Straw is one of the main by-products of crop harvesting in China, and its yield is very rich. At present, the main treatment methods for straw are straw returning to field, manufacturing artificial silk and artificial cotton, being used as biomass fuel, and being used as papermaking raw material, etc. The utilization rate is low. The powder obtained by superfine crushing of straw can be used as a biodegradable material, which can replace petroleum-based products (plastics) in the manufacturing of films, sheets, and injection molding grade products, and has degradability. The application of the superfine powder in biogas can not only increase the yield but also increase the service life. The straw in powder state can also improve the extraction efficiency of cellulose and hemicellulose.

[0003] Publication No. CN221208386U discloses a biomass straw grading crushing equipment. Dust generated during straw crushing can be reduced by adding a dust removal device, which avoids the environmental impact of excessive dust floating into the room. Moreover, the crushing effect is improved based on the original basis, and the crushing is more complete, which is not easy to leave residues. The crushed straw is further utilized, which is conducive to the long-term development of energy saving and environmental protection. Moreover, the use of straw as fertilizer saves a large amount of economic expenditure. The material conveying pipe is inclined, which facilitates the discharge of the crushed straw inside and easy post-conveying. The inside of the crushing box is provided with a baffle and an inclined plate to guide the entering and discharging straw, further improving the processing efficiency. Moreover, the inside of the crushing box is provided with a separation frame, and the straw is discharged through the through holes in the inside, which can improve the uniformity during crushing and avoid the accumulation of a large amount of straw. Although the biomass straw grading crushing equipment can facilitate the discharge of the crushed straw inside by setting the material conveying pipe to be inclined, which is easy for post-conveying, and the inside of the crushing box is provided with a baffle and an inclined plate to guide the entering and discharging straw, further improving the processing efficiency, there are still some problems in the actual use process. During the superfine crushing of straw, the phenomenon of blockage and jamming occurs. If the water content of the straw is too high (more than 20%) or the feeding is too fast, the material in the crushing cavity will accumulate, thereby affecting the crushing of the straw. Since the straw fiber has a high content of lignin and cellulose, it forms a tight cell wall structure. Moreover, a high water content of the straw (such as fresh straw) will increase the fiber toughness and reduce the crushing efficiency, resulting in the phenomenon of uncut straw fiber during the pre-crushing of the straw, which leads to the phenomenon of crushing cavity blockage during the subsequent superfine crushing of the straw, thereby affecting the crushing efficiency of the straw.

[0004] Therefore, the biomass straw superfine crushing equipment and method are provided to solve the problems in the background. SUMMARY

[0023] Compared with the prior art, the beneficial effects of the present invention are as follows: This biomass straw ultrafine crushing equipment and method utilizes the annular crushing outer blade on the outside of the annular cutting frame to initially cut and crush the biomass straw, and utilizes the annular crushing inner blade inside the annular cutting frame and the multiple blades at the ends of the multiple horizontal cutting blades to perform secondary cutting of the biomass straw, which facilitates the cutting of biomass straw fibers and avoids the phenomenon of biomass straw fibers sticking together, thereby affecting the crushing efficiency of biomass straw. The biomass straw is clamped on both sides using a clamping inclined plate and inclined rollers. Through clamping and clamping, the top plate of the clamping plate is easily conveyed quantitatively, thereby facilitating the pre-crushing of biomass straw. The specific details are as follows: 1. By setting up a pre-crushing mechanism, the inspection cover can be opened using the connecting hinge for easy maintenance of the pre-crushing box. Simultaneously, the rotating motor drives the rotating main gear and rotating heating tube to rotate. Utilizing the meshing connection between the rotating main gear, rotating driven gear, and meshing gear ring, the meshing gear ring drives the connecting rotating disk and the annular cutting frame to rotate. The annular crushing outer blades on the outer side of the annular cutting frame perform initial crushing of the biomass straw. When the biomass straw contains a certain amount of moisture, it will push open the protective baffle through the through groove inside the annular cutting frame. The rotating main gear then drives the rotating heating tube and connecting bracket to rotate. Since the rotating heating tube rotates in the opposite direction to the annular cutting frame, the connecting bracket drives the multiple horizontal cutting blades to rotate in the opposite direction. The annular crushing inner blade inside the annular cutting frame and the multiple cutting heads at the ends of the multiple horizontal cutting blades perform secondary crushing of the biomass straw, facilitating the cutting of biomass straw fibers and preventing the biomass from... The sticking of straw fibers affects the crushing efficiency of biomass straw. After being cut by the annular crushing inner blade and multiple blades, the sticking biomass straw fibers fall into the annular cutting frame. The vertical and horizontal cutters inside the connecting support repeatedly cut and crush the biomass straw until it can pass through the first and second through holes. During the cutting of biomass straw, the heating fan and spiral heater inside the drying heating box generate a certain amount of hot air, which is blown into the pre-crushing box through the rotating heating tube to heat the biomass straw, thereby reducing the moisture content of the biomass straw. This prevents the cut biomass straw from clogging the ultrafine crushing equipment body during ultrafine crushing, thus affecting the crushing efficiency of biomass straw. At the same time, the fine cutting and crushing of biomass straw facilitates subsequent ultrafine crushing, thereby improving the crushing efficiency of biomass straw and preventing equipment blockage. 2. By setting up a pressing and conveying mechanism, not only can the ultra-fine crushing equipment body at the bottom of the telescopic connecting cover be used for ultra-fine crushing of biomass straw, but the biomass straw can also be placed on the conveyor belt. The conveyor motor is started to drive the sprocket transmission assembly and conveyor rollers to rotate. Utilizing the transmission connection between the conveyor rollers and the conveyor belt, the biomass straw can be conveyed. At the same time, the pressing cylinder is activated to drive the pressing sliding plate to descend. When the top roller inside the pressing top plate contacts the top of the biomass straw, the elastic force of the connecting spring is used to press the biomass straw. Simultaneously, under the action of the pressing rotating rod, the pressing sliding sleeve drives the pressing inclined plate and the inclined roller to move closer to each other. The pressing inclined plate and the inclined roller clamp the two sides of the biomass straw. Through clamping and pressing, it is convenient to quantitatively convey the pressing top plate, thereby facilitating the pre-crushing of biomass straw. Attached Figure Description

A pressing and conveying mechanism 2 is provided at the bottom of the pre-crushing mechanism 1, and a pressing sliding plate 214 is provided on one side of the top of the pressing and conveying mechanism 2. The pre-crushing mechanism 1 includes a pre-crushing box 101, and connecting hinges 102 are symmetrically rotatably connected to one side of the top of the pre-crushing box 101. Inspection covers 103 are rotatably connected to the outer sides of the two connecting hinges 102. The pre-crushing box 101... The interior is symmetrically connected to several driven gears 104 on both sides. Engaging gear rings 105 are meshed with the outer sides of the driven gears 104. A connecting rotating disk 106 is fixedly connected to one side of each of the two engaging gear rings 105. A rotating main gear 107 is rotatably connected to the inner side of the driven gears 104. A rotating heating tube 108 is fixedly connected between the two main gears 107. A drying heating box 109 is fixedly installed on the outer side of the pre-crushing box 101 near the outer side of the main gear 107. A protective device is fixedly installed on one side of the interior of the drying heating box 109. A heating fan 111 and a spiral heater 112 are fixedly installed on the inner side of the dust screen 110 and the drying heating box 109, respectively, near the dust screen 110. A rotating motor 126 is fixedly installed on the side of the pre-crushing box 101 away from the drying heating box 109. The output end of the rotating motor 126 is fixedly connected to the rotating main gear 107. A ring cutting frame 113 is fixedly connected between the rotating disks 106. Several through slots 114 are fixedly installed inside the ring cutting frame 113. A ring crusher is fixedly installed on the outer side of the ring cutting frame 113 near the through slots 114. The outer crushing blade 115 opens the inspection cover 103 via the connecting hinge 102, facilitating maintenance of the pre-crushing box 101. Simultaneously, the rotating motor 126 is started, driving the rotating main gear 107 and the rotating heating tube 108 to rotate. Utilizing the meshing connection between the rotating main gear 107, the rotating driven gear 104, and the meshing gear ring 105, the meshing gear ring 105 drives the connecting rotating disk 106 and the annular cutting frame 113 to rotate. The annular crushing blade 115 on the outside of the annular cutting frame 113 performs preliminary cutting and crushing of biomass straw.

[0028] Please see Figures 4-8An annular inner crushing blade 116 is fixedly installed on the inner side of the annular cutting frame 113 near the through groove 114. Spring hinges 117 are symmetrically installed on the side of the annular cutting frame 113 near the annular inner crushing blade 116. A protective baffle 118 is rotatably connected to the outer sides of the two spring hinges 117. A first through hole 119 is opened inside the protective baffle 118.

Multiple horizontal cutting blades 122 are fixedly installed at the ends of the connecting brackets 121. Multiple blade heads 123 are fixedly installed at the ends of the multiple horizontal cutting blades 122. When the biomass straw contains a certain amount of... When the biomass straw is moist, the protective baffle 118 is pushed open by the through groove 114 inside the annular cutting frame 113. The rotating main gear 107 drives the rotating heating tube 108 and the connecting bracket 121 to rotate. Since the rotating heating tube 108 rotates in the opposite direction to the annular cutting frame 113, the connecting bracket 121 drives the multiple horizontal cutting blades 122 to rotate in the opposite direction. The annular crushing inner blade 116 inside the annular cutting frame 113 and the multiple blade heads 123 at the ends of the multiple horizontal cutting blades 122 are used to perform secondary cutting of the biomass straw, which facilitates the cutting of biomass straw fibers and avoids the phenomenon of biomass straw fibers sticking together, thereby affecting the crushing efficiency of biomass straw.

[0029] Please see Figures 4-9 Vertical cutters 124 are fixedly installed on both sides of the central connecting bracket 121, and several horizontal cutters 125 are fixedly installed between the connecting brackets 121. Adhesive biomass straw fibers fall into the interior of the annular cutting frame 113 after being cut by the annular crushing inner blade 116 and multiple cutter heads 123. The biomass straw is repeatedly cut and crushed using the vertical cutters 124 and horizontal cutters 125 inside the connecting bracket 121 until it can pass through the first through hole 119 and the second through hole 120. During the cutting of the biomass straw, a drying heating box 1 is used. The internal heating fan 111 and spiral heater 112 generate a certain amount of hot air, which is blown into the pre-crushing box 101 through the rotating heating tube 108, thereby heating the biomass straw and reducing its moisture content. This prevents the ultrafine crushing equipment body 203 from becoming clogged during ultrafine crushing of the cut biomass straw, thus affecting the crushing efficiency of the biomass straw. At the same time, the biomass straw is finely cut and crushed, which facilitates subsequent ultrafine crushing, thereby improving the crushing efficiency of the biomass straw and preventing equipment blockage.

[0030] Please see Figure 1 , Figures 9-10The pressing and conveying mechanism 2 includes a crushing workbench 201, a pre-crushing box 101 fixedly installed on the top of the crushing workbench 201, a telescopic connecting cover 202 fixedly installed on the bottom of the pre-crushing box 101, an ultrafine pulverizing equipment body 203 arranged inside the telescopic connecting cover 202, a reinforcing diagonal brace 204 fixedly installed on one side of the top of the crushing workbench 201, a conveying bracket 205 fixedly installed on the top of the reinforcing diagonal brace 204, a sprocket limiting cover 206 fixedly installed on the outside of the conveying bracket 205, and a conveying motor 207 fixedly installed on one side of the inside of the sprocket limiting cover 206.

The outer sides of the two conveying rollers 209 are connected to a conveyor belt 210. The ultra-fine crushing equipment body 203 at the bottom of the telescopic connecting cover 202 is used to crush the biomass straw. At the same time, the biomass straw is put into the conveyor belt 210. The conveying motor 207 is started to drive the sprocket drive assembly 208 and the conveying rollers 209 to rotate.

[0031] Please see Figures 9-11A fixed bracket 211 is fixedly installed on the top of the conveyor bracket 205. A supporting top plate 212 is fixedly installed on the top of the fixed bracket 211.

A top roller 226 is rotatably connected to the inner bottom of the clamping top plate 225. When the clamping cylinder 213 is activated, it drives the clamping sliding plate 214 to descend. When the top roller 226 inside the clamping top plate 225... When in contact with the top of the biomass straw, the elastic force of the connecting spring 224 is used to compress the biomass straw. At the same time, under the action of the compression rotating rod 217, the compression sliding sleeve 218 drives the compression inclined plate 222 and the inclined roller 223 to move closer to each other. The compression inclined plate 222 and the inclined roller 223 clamp the two sides of the biomass straw. Through clamping and compression, it is convenient to quantitatively convey the compression top plate 225, thereby facilitating the pre-crushing of the biomass straw.

[0032] Working principle: Before using this biomass straw ultrafine crushing equipment and method, it is necessary to check the overall condition of the device to ensure it can operate normally. Figure 1 - Figure 11As shown, firstly, the ultra-fine pulverizing equipment body 203 at the bottom of the telescopic connecting cover 202 is used to ultra-finely pulverize the biomass straw. Simultaneously, the biomass straw is placed onto the conveyor belt 210. The conveyor motor 207 is started, driving the sprocket transmission assembly 208 and the conveyor roller 209 to rotate. Utilizing the transmission connection between the conveyor roller 209 and the conveyor belt 210, the biomass straw can be conveyed. At the same time, the pressing cylinder 213 is activated, causing the pressing sliding plate 214 to descend. When the top plate 225 inside the pressing top plate... When the roller 226 contacts the top of the biomass straw, the connecting spring 224 is used to press the biomass straw. At the same time, under the action of the pressing rotating rod 217, the pressing sliding sleeve 218 drives the pressing inclined plate 222 and the inclined roller 223 to move closer to each other. The pressing inclined plate 222 and the inclined roller 223 clamp the two sides of the biomass straw. Through clamping and pressing, it is convenient to quantitatively convey the pressing top plate 225, thereby facilitating the pre-crushing of the biomass straw.

[0033] Secondly, the inspection cover 103 is opened using the connecting hinge 102 to facilitate maintenance of the pre-crushing box 101. Simultaneously, the rotating motor 126 is started, driving the rotating main gear 107 and the rotating heating tube 108 to rotate. Utilizing the meshing connection between the rotating main gear 107, the rotating driven gear 104, and the meshing gear ring 105, the meshing gear ring 105 drives the connecting rotating disk 106 and the annular cutting frame 113 to rotate. The annular crushing outer blades 115 on the outer side of the annular cutting frame 113 perform preliminary cutting and crushing of the biomass straw. When the biomass straw contains a certain amount of moisture, it will pass through the annular cutting frame 113... The internal through groove 114 pushes open the protective baffle 118. The rotating main gear 107 drives the rotating heating tube 108 and the connecting bracket 121 to rotate. Since the rotating heating tube 108 rotates in the opposite direction to the annular cutting frame 113, the connecting bracket 121 drives the multiple horizontal cutting blades 122 to rotate in the opposite direction. The annular crushing inner blade 116 inside the annular cutting frame 113 and the multiple blade heads 123 at the ends of the multiple horizontal cutting blades 122 are used to perform secondary cutting of biomass straw, which facilitates the cutting of biomass straw fibers and avoids the phenomenon of biomass straw fibers sticking together, thereby affecting the crushing efficiency of biomass straw.

[0034] Finally, the adhered biomass straw fibers, after being cut by the annular crushing inner blade 116 and multiple blades 123, fall into the interior of the annular cutting frame 113. The biomass straw is repeatedly cut and crushed by the vertical cutter 124 and horizontal cutter 125 inside the connecting bracket 121 until the biomass straw can pass through the first through hole 119 and the second through hole 120. During the cutting of biomass straw, a certain amount of hot air is generated by the heating fan 111 and spiral heater 112 inside the drying heating box 109, and blown into the interior of the pre-crushing box 101 by rotating the heating tube 108, thereby heating the biomass straw and reducing its moisture content. This prevents the cut biomass straw from clogging the ultrafine crushing equipment body 203 during ultrafine crushing, which would affect the crushing efficiency of the biomass straw. At the same time, the fine cutting and crushing of the biomass straw facilitates subsequent ultrafine crushing, thereby improving the crushing efficiency of the biomass straw and preventing equipment clogging.
