Description

Technical Field

[0001] This invention belongs to the technical field of wood waste processing equipment, specifically, it relates to an apparatus for producing reconstituted wood raw materials based on the recycling of wood waste. Background Technology

[0002] Wood has advantages such as light weight, high strength-to-weight ratio, good elasticity, impact resistance, rich and beautiful textures and colors, and easy processing. It has been regarded as an important raw material since ancient times.

[0003] The formwork, supporting timber, scaffolding mats, and timber generated during the construction, renovation, and expansion of houses, as well as the wooden flooring, wooden doors, wooden cabinets, wooden ceilings, and wooden decorative moldings replaced during the decoration or renovation of home and commercial spaces, and the wood scraps and sawdust generated during the decoration cutting process, all generate waste wood. This waste wood can be crushed into powder and made into square planks or biomass fuel for reuse.

[0004] Chinese utility model patent CN211386278U discloses a wood waste crushing and processing device, including a supporting base box. A crusher box is installed on the top of the supporting base box. A material guide port is opened through the top of the supporting base box. A material discharge pipe is installed inside the material guide port. A sealing top cover is installed inside the supporting base box corresponding to the position of the material discharge pipe. A screen plate is installed at the bottom of the sealing top cover. A debris collection box is installed at the bottom of the supporting base box corresponding to the position of the screen plate. A recycling pipe is installed through the outer wall of the sealing top cover and one side of the inner wall of the supporting base box. A feed hopper is embedded in one side of the top of the crusher box. A fixed base is installed at the bottom of the feed hopper. A valve plate is embedded in the fixed base.

[0005] While this pulverizing device can crush wood waste into powder for subsequent processing and reuse, some waste wood may contain nails. These nails are crushed along with the wood, necessitating the screening of metal powder from the wood powder. Conventional metal powder screening uses magnetic adsorption to extract the metal powder from the wood powder, such as a belt magnetic separator suspended above the conveyor belt or a rotating separator with built-in magnetic strips along the wood powder conveying path. However, during the conveying process, the metal powder at the bottom of the wood powder or encased in the wood powder cannot be completely separated. This results in a significant amount of metal powder remaining in the screened wood powder, affecting subsequent processing and reuse, and reducing the amount of metal powder separated. Summary of the Invention

[0006] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0007] To address the issue raised in the background section where metal powder at the bottom of the wood flour or encased in the wood flour cannot be completely separated during transport, resulting in a significant amount of metal powder remaining in the screened wood flour, which affects subsequent processing and reuse of the wood flour and reduces the amount of metal powder separated, the present invention adopts the following technical solution.

[0008] One objective of this invention is to provide an apparatus for producing reconstituted wood raw materials based on the recycling of wood waste. The apparatus includes a hammer mill, a feeding conveyor at the inlet of the hammer mill, a negative pressure pneumatic conveyor mounted on the side wall of the hammer mill, a conveying pipe detachably connected to the outlet of the negative pressure pneumatic conveyor, a storage hopper detachably connected to the end of the conveying pipe, a spiral feeding pipe connected to the outlet of the storage hopper, an electromagnet placed on the ground, and an adsorption column magnetically attracted to the upper end of the electromagnet. The adsorption column is inserted into the center of the spiral feeding pipe. When the electromagnet is energized, it attracts the adsorption column, creating a secondary magnetic field aligned with the direction of the electromagnet's magnetic field. As the wood powder moves inside the spiral feeding pipe, metal powder within the wood powder is adsorbed onto the inner wall of the spiral feeding pipe.

[0009] In the above technical solution, when the electromagnet is energized, it will attract the vertical column magnetically. The attracted vertical column can be magnetized to form a secondary magnetic field that is in the same direction as the magnetic field of the electromagnet. The generated magnetic field will attract the metal powder in the wood powder to the inner wall of the spiral feed tube.

[0010] Based on this, a rotary valve is detachably connected to the discharge end of the storage hopper, and a spiral feed pipe is connected to the discharge port of the rotary valve. A reciprocating moving component is installed on the rotary valve, which drives the spiral feed pipe to move up and down reciprocally when the rotary valve is working.

[0011] In the above technical solution, the motor drives the rotor to rotate at high speed through the transmission device. After the waste wood and other materials enter the cavity from the upper feed port, they are repeatedly impacted and beaten by the high-speed rotating hammer until they are crushed. The materials that meet the particle size requirements will be discharged through the grate gaps of the grate bar, while the unqualified coarse materials will remain in the cavity to continue to be crushed.

[0012] Based on this, an adsorption base is fixedly connected to the bottom of the adsorption column. The adsorption base is adsorbed to the upper end of the electromagnet. An outer adsorption ring is detachably connected to the upper end of the adsorption base. The outer adsorption ring wraps around the outside of the spiral feed tube. A through groove is provided on the outer adsorption ring. The end of the spiral feed tube passes through the through groove. The outer adsorption ring and the adsorption column are magnetized synchronously to form a closed magnetic field, so that the magnetic field inside the spiral feed tube is evenly distributed.

[0013] In the above technical solution, by setting the outer adsorption ring on the outside of the spiral feed tube and connecting it to the adsorption base, the outer adsorption ring and the adsorption column can be magnetized synchronously. The magnetic fields of the adsorption column and the outer adsorption ring are completely consistent, forming a closed magnetic field that makes the magnetic field distribution inside the spiral feed tube uniform.

[0014] Based on this, the rotary valve includes a housing, an impeller, a main shaft, and a drive motor. The drive motor is equipped with a reducer, and the impeller is star-shaped and fits tightly against the inner wall of the housing.

[0015] The reciprocating assembly includes a drive wheel, a receiving plate, a sliding rod, a transmission plate, and a rotating shaft. One end of the main shaft of the rotary valve protrudes from the housing, and the drive wheel is detachably connected to the protruding end. A connector is fixedly connected to the upper end of the spiral feed tube, and the connector is flexibly connected to the discharge port of the rotary valve. The receiving plate is rotatably connected to the outer wall of the drive wheel near its outer edge. A sliding rod slides inside the receiving plate, and the bottom of the sliding rod is fixedly connected to the transmission plate. A rotating shaft is rotatably connected between the transmission plate and the connector. The drive wheel rotates with the main shaft of the rotary valve, causing the receiving plate to rotate around the center of the drive wheel. In conjunction with the rotational connection between the rotating shaft and the connector, the connector drives the spiral feed tube below to reciprocate up and down.

[0016] In the above technical solution, when the star-shaped unloader is working and conveying wood powder downwards, the drive wheel rotates with the main shaft of the star-shaped unloader, which in turn drives the collection plate to rotate around the center of the drive wheel. In addition, with the rotational connection between the rotating shaft and the connector, the connector can drive the spiral feed pipe below to move up and down reciprocally when the drive wheel rotates.

[0017] Based on this, a rubber hose is detachably connected to the upper end of the connector, and a connecting plate is detachably connected to the upper end of the rubber hose. The connecting plate is detachably connected to the discharge port of the rotary valve.

[0018] In the above technical solution, the connection between the connector and the star-shaped unloader is made flexible by using a rubber hose, which does not affect the up-and-down reciprocating motion of the spiral feed pipe and the connector.

[0019] Based on this, the feeding and conveying device includes a drive roller, a motor, a conveyor belt, a reducer, and a support frame. The conveyor belt is sleeved on the outside of the two drive rollers, and the drive rollers are rotatably connected to a support frame that is supported on the ground. The motor and reducer are mounted on the support frame. The motor and reducer drive the rollers to rotate, causing the conveyor belt to rotate and transport the material forward.

[0020] Based on this, the hammer mill includes a rotor consisting of a main shaft, a cavity, manganese steel grate bars, hammer discs, pins, and hammers. The bottom of the cavity is equipped with manganese steel grate bars with grate slots. An external transmission device consisting of a motor, a reducer, and a pulley or coupling is installed. The motor drives the rotor to rotate at high speed through the transmission device.

[0021] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0022] 1. In this invention, when wood powder is discharged downwards through the spiral feeding pipe, extending the discharge path of the wood powder effectively spreads it out, preventing excessive thickness accumulation that could cause metal particles to be encapsulated, thus improving the separation rate of the metal powder. The outer adsorption ring, positioned on the outside of the spiral feeding pipe and connected to the adsorption base, allows for synchronous magnetization of the outer adsorption ring and the adsorption column. The magnetic fields of the adsorption column and the outer adsorption ring are completely consistent, forming a closed magnetic field. This ensures a uniform magnetic field distribution inside the spiral feeding pipe, preventing localized over- or under-strength conditions. This effectively adsorbs fine metal powder without causing wood powder jamming due to excessively strong local magnetic fields. Furthermore, the outer adsorption ring ensures that the magnetic field generated by the electromagnet preferentially passes through the high-permeability outer adsorption ring and the adsorption column to form a closed loop, preventing diffusion into the air. This results in a higher magnetic field strength inside the spiral tube, significantly attenuating stray magnetic fields outside the equipment and reducing the impact on surrounding equipment and operators.

[0023] 2. In this invention, the drive wheel rotates with the main shaft of the star-shaped unloader, which in turn drives the receiving plate to rotate around the center of the drive wheel. Combined with the rotational connection between the rotating shaft and the connector, the drive wheel rotates, causing the connector to drive the spiral feeding tube below to move up and down reciprocally. The up-and-down reciprocating motion of the spiral feeding tube during discharge makes the flow trajectory of wood powder inside the spiral feeding tube more irregular, resulting in a larger contact area between the wood powder and the inside of the spiral feeding tube, further improving the separation rate of metal powder. When it is necessary to discharge the metal powder inside the spiral feeding tube, the up-and-down reciprocating spiral feeding tube can assist in the discharge of metal powder, reducing the residue of metal powder.

[0036] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0037] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0038] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that mutually excludes other embodiments. The present invention provides the following embodiments.

[0039] like Figures 1-4 As shown, it is a schematic diagram of the structure of a device for producing reconstituted wood raw materials based on the recycling of wood waste according to a preferred embodiment of the present invention. The device for producing reconstituted wood raw materials based on the recycling of wood waste in this embodiment includes a hammer crusher 101. The feed inlet of the hammer crusher 101 is provided with a feeding conveying device 100. A negative pressure pneumatic conveyor 102 is installed on the side wall of the hammer crusher 101. The discharge port of the negative pressure pneumatic conveyor 102 is detachably connected to a conveying pipe 103. The end of the conveying pipe 103 is detachably connected to a storage hopper 104.

[0040] Waste boards or wood blocks are placed on the upper end of the feeding conveyor 100 and conveyed to the feed inlet of the hammer crusher 101 through the feeding conveyor 100. The hammer crusher 101 crushes the waste boards or wood blocks, and the crushed wood powder is conveyed through the negative pressure pneumatic conveyor 102 and the conveying pipe 103 and finally enters the interior of the storage hopper 104.

[0041] The feeding and conveying device 100 includes a drive roller, a motor, a conveyor belt, a reducer, and a support frame. The two drive rollers are fitted with a conveyor belt, and the motor and reducer drive the rollers to rotate, causing the conveyor belt to rotate and convey the material forward. The drive rollers are rotatably connected to a support frame that is supported on the ground.

[0042] The core of the hammer crusher 101 is a rotor composed of a main shaft, hammer disc, pin shaft and high manganese steel or high chromium cast iron hammers. The bottom of the cavity is equipped with manganese steel grate bars with slits. The external part is equipped with a transmission device consisting of a motor, reducer and pulley or coupling.

[0043] The motor drives the rotor to rotate at high speed through the transmission device. After the waste wood and other materials enter the cavity from the upper feed port, they are repeatedly impacted and beaten by the high-speed rotating hammer until they are crushed. The materials that meet the particle size requirements will be discharged through the grate gaps of the grate bar, while the unqualified coarse materials will remain in the cavity to continue to be crushed.

[0044] To ensure a more uniform distribution of wood flour from hopper 104, the specific structure can be as follows: Figure 1-3 In the embodiment shown, the discharge end of the storage hopper 104 is detachably connected to a star-shaped unloader 105. The star-shaped unloader 105 includes a housing, an impeller, a main shaft, and a drive motor. A reducer is installed on the drive motor. The impeller is star-shaped and fits tightly against the inner wall of the housing.

[0045] The motor drives the main shaft to rotate the impeller. The wood powder in the storage hopper 104 falls into the chamber between the impeller blades and is discharged from the lower outlet as the impeller rotates. At the same time, the impeller and the casing are sealed together to isolate the upper and lower airflow channels and prevent negative pressure leakage or dust from flying.

[0046] like Figure 5 As shown, it is a schematic diagram of the metal powder adsorption component in this embodiment. The discharge port of the star-shaped unloader 105 is detachably connected to the spiral discharge pipe 200. An electromagnet 202 is placed on the ground. The upper end of the electromagnet 202 is magnetically attracted to the adsorption base 201. The upper end of the adsorption base 201 is fixedly connected to the adsorption column 203 inserted into the center of the spiral discharge pipe 200.

[0047] When the electromagnet 202 is energized, it attracts the adsorption base 201. The adsorption base 201 and the adsorption column 203 can be magnetized to form a secondary magnetic field in the same direction as the magnetic field of the electromagnet 202. When the wood powder is discharged downward through the spiral feed tube 200, the discharge path of the wood powder is extended. In addition, the magnetic field generated by the adsorption column 203 adsorbs the metal powder in the wood powder onto the inner wall of the spiral feed tube 200. When the wood powder falls along the path of the spiral feed tube 200, it can effectively spread the wood powder, avoid excessive thickness accumulation which would cause the metal particles to be wrapped, and improve the separation rate of the metal powder.

[0048] Because the wood powder moves downwards at a uniform speed inside the spiral feed tube 200, the metal powder encased in the wood powder cannot reach the surface. Therefore, in order to accelerate the discharge of wood powder and create a tumbling effect for the wood powder as it moves inside the spiral feed tube 200, the specific structure can be as follows: Figure 6 as well as Figure 7 In the embodiment shown, the main shaft of the star-shaped unloader 105 extends out of the outer casing at one end, and a drive wheel 300 is detachably connected to the protruding end. A connector 204 is fixedly connected to the upper end of the spiral discharge pipe 200. A rubber hose 205 is detachably connected to the upper end of the connector 204. A connecting plate 206 is detachably connected to the upper end of the rubber hose 205. The connecting plate 206 is detachably connected to the discharge port of the star-shaped unloader 105. A receiving plate 301 is rotatably connected to the outer wall of the drive wheel 300 near the outer edge. A sliding rod 302 slides inside the receiving plate 301. A drive plate 303 is fixedly connected to the bottom of the sliding rod 302. A rotating shaft 304 is rotatably connected between the drive plate 303 and the connector 204.

[0049] When the rotary valve 105 is working and conveying wood powder downwards, the drive wheel 300 rotates with the main shaft of the rotary valve 105, which in turn drives the collection plate 301 to rotate around the center of the drive wheel 300. Combined with the rotational connection between the rotating shaft 304 and the connector 204, the rotation of the drive wheel 300 drives the connector 204 to move the lower spiral feed pipe 200 up and down reciprocally. The rubber hose 205 provides a flexible connection between the connector 204 and the rotary valve 105. The reciprocating motion of the spiral feed tube 200 and the connector 204 is not affected. The reciprocating motion of the spiral feed tube 200 during discharge makes the flow trajectory of wood powder inside the spiral feed tube 200 more irregular, resulting in a larger contact area between the wood powder and the inside of the spiral feed tube 200, which further improves the separation rate of metal powder. When it is necessary to discharge the metal powder inside the spiral feed tube 200, the reciprocating motion of the spiral feed tube 200 can assist in the discharge of metal powder and reduce the residue of metal powder.

[0050] It is worth noting that the aforementioned transmission wheel 300, storage plate 301, sliding rod 302, transmission plate 303, and rotating shaft 304 are reciprocating components in this embodiment. The reciprocating components include, but are not limited to, the transmission wheel 300, storage plate 301, sliding rod 302, transmission plate 303, and rotating shaft 304. Any component that enables the connector 204 and the spiral feed tube 200 to move up and down reciprocally can be used in this embodiment.

[0051] Because the adsorption column 203 is located at the center of the spiral feed tube 200, the magnetic field in one part of the spiral feed tube 200 will be too strong and the magnetic field in another part will be too weak. In order to make the magnetic field coverage of the spiral feed tube 200 more comprehensive, so that the inner wall of the spiral feed tube 200 can adsorb the metal powder, the specific structure can be as follows: Figure 8 In the embodiment shown, an outer adsorption ring 207 is detachably connected to the upper external part of the adsorption base 201. The outer adsorption ring 207 wraps around the outside of the spiral feed tube 200. A through groove 208 is provided on the outer adsorption ring 207, and the end of the spiral feed tube 200 passes through the through groove 208.

[0052] By setting the outer adsorption ring 207 on the outside of the spiral feed tube 200 and connecting it to the adsorption base 201, the outer adsorption ring 207 and the adsorption column 203 can be magnetized synchronously. The magnetic fields of the adsorption column 203 and the outer adsorption ring 207 are completely consistent, forming a closed magnetic field. This ensures that the magnetic field distribution inside the spiral feed tube 200 is uniform, without any local over-strength or under-strength. This allows for the adsorption of fine metal powder without causing wood powder to get stuck due to excessively strong local magnetic fields. Furthermore, the outer adsorption ring 207 ensures that the magnetic field generated by the electromagnet 202 preferentially passes through the outer adsorption ring 207 and the adsorption column 203, which have high magnetic permeability, to form a closed loop, preventing it from diffusing into the air. This results in a higher magnetic field strength inside the spiral tube, which in turn significantly attenuates stray magnetic fields outside the equipment, reducing the impact on surrounding equipment and operators.

[0053] The above description, in conjunction with specific embodiments, provides a further detailed explanation of the present invention. It should not be construed that the specific implementation of the present invention is limited to these descriptions. For those skilled in the art, several simple deductions or substitutions can be made without departing from the concept of the present invention, and all such deductions or substitutions should be considered to fall within the scope of protection defined by the claims submitted herein.
