Description

Technical Field

[0001] The utility model relates to the field of particle board manufacturing, and more specifically, to a particle board production raw material processing device. Background Art

[0002] Crop straw is a valuable renewable resource, but most of it is discarded or burned instead of being properly developed and utilized, resulting in a waste of resources. In addition, burning also causes certain environmental pollution.

[0003] In recent years, with the continuous development of the building materials field, straw particleboard has been increasingly used in packaging, furniture, decoration and other scenarios. This is mainly because straw particleboard is more environmentally friendly, has high strength, small weight and good sound insulation and heat insulation effects.

[0004] For this reason, the production process and equipment of straw particleboard have also become one of the current research focuses. For example, the patent document CN207266895 U "Continuous Multiple Sorting Device" proposes a set of sorting devices, which can remove ferromagnetic and non-ferromagnetic impurities in straw materials in a single device through the cooperation of a semi-magnetic roller and a negative pressure channel. However, if the straw is first made into straw shavings and then sorted using the device, impurities will cause damage to the front equipment; if the straw coarse material is sorted directly, the effect of impurity removal will be difficult to guarantee. Therefore, how to improve the impurity removal effect while reducing the impact on other production equipment has become a technical problem that needs to be solved urgently. Utility Model Content

[0005] In view of the above problems, the utility model provides a particleboard raw material processing device, which adds a scattering machine before impurities are removed, optimizes the processing procedure, and improves the impurity removal effect.

[0006] In order to achieve the above-mentioned purpose, the utility model provides a particleboard raw material processing device, including: a shredder, suitable for chopping straw to obtain straw fragments; a scatterer, including: a casing, suitable for receiving the above-mentioned straw fragments; a rotating shaft, rotatably mounted on two opposite inner walls of the casing; at least one rotating toothed plate, radially extending from the rotating shaft; a driving motor, mounted on the outside of the casing and configured to drive the rotating shaft to drive the rotating toothed plate to rotate; a fixed toothed plate, horizontally extending from the inner wall of the casing toward the rotating shaft, the upper surface of the fixed toothed plate forming a scattering surface; a plurality of fixed teeth of the fixed toothed plate cooperate with a plurality of rotating teeth of each of the rotating toothed plates, so as to continuously scatter the straw fragments located on the scattering surface when the rotating toothed plate rotates; and a magnetic separator, arranged at the lower part of the scatterer, and configured to remove magnetic impurities in the above-mentioned straw fragments after being scattered by using magnetic force.

[0007] In an illustrative embodiment, the shredder includes: a frame; a conveyor belt installed at the lower part of the frame; a cloth roller rotatably connected to the frame above the conveyor belt and configured to spread out the bundled straw transported by the conveyor belt in a clockwise rotation state and compact the bundled straw transported by the conveyor belt in a counterclockwise rotation state; a shredder roller rotatably connected to the frame above the conveyor belt, a plurality of cutting knives being provided on the shredder roller, and the cutting knives being configured to shred the straw to obtain straw shreds when the shredder roller rotates.

[0008] In an illustrative embodiment, a plurality of rows of arc-shaped pressing plates distributed in the axial direction and extending in the circumferential direction are arranged on the outer peripheral surface of the above-mentioned distribution roller, and the above-mentioned arc-shaped pressing plates rotate with the above-mentioned distribution roller to distribute the bundled straw transported by the above-mentioned conveyor belt.

[0009] In an illustrative embodiment, the plurality of cutting knives are divided into a plurality of cutting knife groups spaced apart in the axial direction of the cutting roller, and the plurality of cutting knives in each cutting knife group are arranged around the cutting roller at intervals.

[0010] In an illustrative embodiment, the cutting knives of two adjacent cutting knife groups are staggered with each other by a preset angle along the circumferential direction.

[0011] In an illustrative embodiment, at least one cutting knife is provided on each axially extending surface of the chopping roller, so that the straw parallel to the axial direction of the chopping roller is cut into at least two sections.

[0012] In an illustrative embodiment, the magnetic separator includes: a body, an upper portion of which is provided with a feed port suitable for receiving the straw fragments from the crusher; a magnetic drum rotatably arranged inside the body, configured to be able to adsorb magnetic impurities in the straw fragments when power is supplied, and to release the magnetic impurities adsorbed on the surface of the magnetic drum when power is stopped; and a driving mechanism installed on the inner wall of the body and configured to drive the magnetic drum to rotate.

[0013] In an illustrative embodiment, the driving mechanism includes a motor and a belt. When the motor is powered on, the motor drives the magnetic roller to rotate via the belt.

[0014] In an illustrative embodiment, a plurality of receiving grooves are formed on the surface of the magnetic drum, so that the straw fragments can fall into the receiving grooves during the rotation of the magnetic drum.

[0015] In an illustrative embodiment, the accommodating grooves are strip grooves extending along the axial direction of the magnetic roller, and are distributed on the outer circumferential surface of the magnetic roller at intervals along the circumferential direction.

[0016] The particleboard raw material processing device provided by the utility model first cuts the straw raw material into segments by a shredder, and the resulting straw fragments are transported to the feed of a scattering machine, and then fall onto the scattering surface formed by a fixed toothed plate, and a driving motor drives the rotating shaft to drive the rotating toothed plate to rotate, so that the rotating toothed plate continuously passes through the scattering surface to scatter the straw fragments. The scattering straw fragments fall into a magnetic separator under the action of gravity, and the magnetic separator uses magnetic force to remove magnetic impurities in the straw fragments. In the slicing process, the water inside the straw will flow out, resulting in the existence of agglomeration in the obtained straw fragments. By setting up a scattering machine to scatter the straw fragments, it is convenient for the magnetic separator to remove impurities, and the impurity removal effect is more effectively improved. In addition, when the shredder slicing the straw, the impurities in the straw have little effect on the shredder; and after the impurities are removed, the processes such as crushing and air separation that are more easily affected by impurities are carried out, which effectively reduces the possibility of equipment failure or even damage.

[0044] Figure 1 It is a schematic diagram of a particle board raw material processing device provided by the utility model.

[0045] Figure 2 It is a cross-sectional view of the dispersing machine provided by the utility model.

[0046] The exemplary embodiment of the utility model provides a particleboard raw material processing device, comprising a shredder 2, a scatterer 1 and a magnetic separator 3. The shredder 2 is used to shred straw raw materials to obtain straw fragments; the scatterer 1 comprises a housing 10, a rotating shaft 11, a fixed toothed plate 13, a driving motor 14 and at least one rotating toothed plate 12. The housing 10 is used to receive straw fragments; the rotating shaft 11 is rotatably mounted on two opposite inner walls of the housing 10; the fixed toothed plate 13 extends horizontally from the inner wall of the housing 10 toward the rotating shaft 11, and the upper surface of the fixed toothed plate 13 is formed as a scattering surface; at least one rotating toothed plate 12 extends radially from the rotating shaft 11; the driving motor 14 is mounted on the outside of the housing 10 and is configured to drive the rotating shaft 11 to drive the rotating toothed plate 12 to rotate; the multiple fixed teeth of the fixed toothed plate 13 cooperate with the multiple rotating teeth of each rotating toothed plate 12 to continuously scatter the straw fragments located on the scattering surface when the rotating toothed plate 12 rotates. The magnetic separator 3 is arranged at the lower part of the scatterer 1 and is configured to remove magnetic impurities in the scattering straw fragments by magnetic force.

[0047] In such an embodiment, the shredder 2 cuts the straw raw material into segments, and the resulting straw fragments are transported to the feed of the scatterer 1. The structure of the scatterer 1 is as follows: Figure 2As shown, the straw fragments fall onto the scattering surface formed by the fixed toothed plate 13, and the driving motor 14 drives the rotating shaft 11 to drive the rotating toothed plate 12 to rotate, so that the rotating toothed plate 12 continuously passes through the scattering surface to scatter the straw fragments. The scattering straw fragments fall into the magnetic separator 3 under the action of gravity, and the magnetic separator 3 uses magnetic force to remove magnetic impurities in the straw fragments. During the segmentation process, the water inside the straw will flow out, resulting in the agglomeration of the obtained straw fragments. By setting up the scatterer 1 to scatter the straw fragments, it is convenient for the magnetic separator 3 to remove impurities, which effectively improves the impurity removal effect. When the shredder 2 cuts the straw raw material into segments, the impurities in the straw raw material have little effect on the operation of the shredder 2.

[0048] According to an embodiment of the present invention, when the rotating toothed plate 12 passes through the scattering surface, the plurality of rotating teeth of the rotating toothed plate 12 and the plurality of fixed teeth on the fixed toothed plate 13 are in an alternating position relationship to form a match.

[0049] In some other embodiments, a plurality of rotating toothed plates 12 may be provided and distributed at intervals along the circumference of the rotating shaft 11 to increase the frequency of the rotating toothed plates 12 passing through the scattering surface and improve the scattering effect.

[0050] like Figure 1 As shown, the straw fragments obtained after being processed by the shredder 2 are transported to the top of the breaker 1 by a transmission mechanism, and the transmission mechanism includes but is not limited to using an auger to facilitate carrying and transporting the straw fragments.

[0051] Figure 3 It is a cross-sectional view of the shredder provided by the utility model.

[0052] According to an embodiment of the utility model, the shredder 2 comprises: a frame, a conveyor belt 20, a cloth roller 21 and a shredder roller 22. The conveyor belt 20 is installed at the lower part of the frame; the cloth roller 21 is rotatably connected to the frame above the conveyor belt 20, and is configured to spread the bundled straw transported by the conveyor belt 20 in response to the clockwise rotation state, and compact the bundled straw transported by the conveyor belt 20 in the counterclockwise rotation state. The shredder roller 22 is rotatably connected to the frame above the conveyor belt 20, and a plurality of cutting knives 220 are arranged on the shredder roller 22, and the cutting knives 220 are configured to shred the straw when the shredder roller 22 rotates to obtain straw shreds.

[0053] In such an embodiment, the bundled straw material is transported to the cloth roller 21 by the conveyor belt 20, and the straw material is flattened / compacted by the rotation of the cloth roller 21, so as to facilitate the chopping roller 22 to chop the straw into straw fragments.

[0054] According to an embodiment of the utility model, the outer peripheral surface of the distribution roller 21 has multiple rows of arc-shaped pressing plates distributed in the axial direction and extending in the circumferential direction. The arc-shaped pressing plates rotate with the distribution roller 21 to distribute the bundled straw transported by the conveyor belt 20.

[0055] Specifically, if Figure 3 As shown, when the distribution roller 21 rotates clockwise, the arc-shaped pressing plate can push away the straw at the upper part of the bundled straw to flatten the straw raw material; when the distribution roller 21 rotates counterclockwise, the arc-shaped pressing plate can compact the bundled straw to facilitate shredding by the shredding roller 22.

[0056] In an exemplary embodiment, the plurality of cutting knives 220 are divided into a plurality of cutting knife groups spaced apart in the axial direction of the cutting roller 22 , and the plurality of cutting knives 220 in each cutting knife group are arranged around the cutting roller 22 at intervals.

[0057] According to an embodiment of the utility model, the multiple cutting knives 220 of two adjacent groups of cutting knife groups are staggered at a preset angle in the circumferential direction so that the multiple cutting knives 220 can continuously cut the straw into segments, thereby avoiding the situation where part of the straw passes through the interval between adjacent cutting knives 220 in the circumferential direction during the movement of the straw with the conveyor belt 20, resulting in the inability to be cut into segments and missing cutting.

[0058] In some other embodiments, at least one cutting knife 220 is provided on each axially extending surface of the chopping roller 22, so that the straw parallel to the circumferential direction of the chopping roller 22 is cut into at least two sections, thereby further reducing the probability of missed cutting.

[0059] Figure 4 It is a cross-sectional view of the magnetic separator provided by the utility model.

[0060] In an exemplary embodiment, the magnetic separator 3 includes a body, a magnetic drum 31 and a driving mechanism. A feed port 30 for receiving straw fragments from the scatterer 1 is provided on the upper part of the body. The magnetic drum 31 is rotatably arranged inside the body, and is configured to be able to adsorb magnetic impurities in the straw fragments when the power is supplied, and release the magnetic impurities adsorbed on the surface when the power is stopped. The driving mechanism is installed on the inner wall of the body, and is configured to drive the magnetic drum 31 to rotate.

[0061] In such an embodiment, the broken straw fragments enter the magnetic separator 3 from the feed port 30. When the straw fragments are powered, the magnetic roller 31 can absorb magnetic impurities when the straw fragments pass through, so that the magnetic impurities adhere to the outer surface of the magnetic roller 31. After all the straw fragments have passed through, the power supply is stopped, and the magnetic roller 31 no longer has magnetism, and the magnetic impurities on the outer surface are separated from the magnetic roller 31. The magnetic roller 31 is driven to rotate by the driving mechanism so that the straw fragments are fully in contact with the outer surface of the magnetic roller 31, thereby improving the impurity removal effect.

[0062] It should be noted that, in order to make the magnetic impurities separate from the magnetic roller 31 as much as possible, when the magnetic roller 31 has no magnetism, the driving mechanism can still drive the magnetic roller 31 to rotate.

[0063] According to the embodiment of the utility model, the driving mechanism includes a motor 32 and a belt 33 . The motor 32 drives the magnetic roller 31 to rotate through the belt 33 after being powered on.

[0064] In some other embodiments, the driving mechanism may also include a motor 32 and a transmission shaft, wherein the rotor of the motor 32 is connected to one end of the transmission shaft, and the magnetic roller 31 is connected to the other end of the transmission shaft.

[0065] In an exemplary embodiment, a plurality of receiving grooves 310 are formed on the surface of the magnetic drum 31 , so that the straw fragments fall into the receiving grooves 310 .

[0066] In such an embodiment, after the straw fragments fall into the receiving groove 310, they can rotate with the magnetic roller 31 in the receiving groove 310, and then leave the receiving groove 310 under the action of gravity. This allows the straw fragments to stay on the surface of the magnetic roller 31 for a longer time, thereby increasing the impurity removal effect.

[0067] According to an embodiment of the present invention, the accommodating grooves 310 are strip-shaped grooves extending along the axial direction of the magnetic drum 31 , and are distributed on the outer circumferential surface of the magnetic drum 31 at intervals along the circumferential direction.

[0068] In such an embodiment, since the straw fragments are processed by the shredder 2, the length of the cut straw segments is difficult to guarantee, and the strip grooves extending axially can better adapt to the shape of the straw fragments and improve the impurity removal effect to a certain extent.
