Description

Technical Field

[0001] This invention belongs to the field of wood chip composting technology, specifically relating to a wood chip composting device and its usage method. Background Technology

[0002] Wood chips are powdery residues such as sawdust and shavings produced during wood processing. With the rapid development of the wood processing, furniture manufacturing, and building decoration industries, the output of wood chips, as a major processing waste, is increasing year by year. To improve material utilization, wood chips are commonly used as fuel, lightweight filler, and raw material for engineered wood products and papermaking. In recent years, wood chips have also been frequently used as composting material. Wood chips are rich in organic carbon components such as cellulose and hemicellulose, and can be converted into high-quality organic fertilizer after composting.

[0003] However, sawdust is loose in texture but prone to caking. If ventilation is inadequate during composting, it can easily lead to an anaerobic environment inside, causing putrefactive decomposition and reducing the efficiency of composting. In current technology, the sawdust is usually turned over manually every few days, but this method is not only inefficient but also makes it difficult to thoroughly turn the sawdust pile, thus affecting the composting efficiency and the quality of the organic fertilizer, causing unnecessary trouble for users.

[0004] Therefore, in order to address the above-mentioned technical problems, it is necessary to provide a wood chip composting device and its usage method.

[0005] The information disclosed in this background section is intended only to enhance the understanding of the overall background of the invention and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Summary of the Invention

[0006] The purpose of this invention is to provide a wood chip composting device and its usage method, which can solve the problem of inconvenient turning of wood chip compost in the prior art.

[0007] To achieve the above objectives, a specific embodiment of the present invention provides the following technical solution:

[0008] A wood chip composting device and its method of use include: a support base, a support reaction component, a turning and mixing mechanism, and an auxiliary turning mechanism.

[0009] The supporting reaction assembly is installed on the supporting base. The supporting reaction assembly includes a composting reaction tank, an end cover adjusting plate, a sliding support plate, and a feeding pipe. The end cover adjusting plate is fixed on the composting reaction tank, the sliding support plate is slidably disposed on the end cover adjusting plate, and the feeding pipe is slidably inserted into the sliding support plate.

[0010] The material turning and mixing mechanism is installed inside the composting reactor. The material turning and mixing mechanism includes a drive shaft tube and multiple material turning blades. Both ends of the drive shaft tube are fixedly connected to the composting reactor with support bearings. Multiple material turning blades are installed on the drive shaft tube, and multiple material turning blades are chiseled with air jets.

[0011] The auxiliary turning mechanism is installed on the drive shaft tube. The auxiliary turning mechanism is used to turn the sawdust fertilizer in the composting reactor and can also help control the turning direction of the sawdust.

[0012] The auxiliary turning mechanism includes a fixed ring tube and multiple auxiliary turning plates. The fixed ring tube is fixed to the drive shaft tube, and multiple air supply connecting pipes are rotatably installed on the fixed ring tube. The auxiliary turning plates are fixed to the other end of the air supply connecting pipes. A dispersion cavity is cut into the auxiliary turning plates, and the air supply connecting pipes are connected to the dispersion cavity. Multiple one-way valves are also installed on the auxiliary turning plates.

[0013] In one or more embodiments of the present invention, the composting reactor is provided with a pair of feed inlets for conveniently pouring composting raw materials into the composting reactor, which facilitates operation and allows for ventilation, enabling oxygen to enter during the turning process. The pair of feed inlets are provided with sealing plates to seal the feed inlets, thereby facilitating the fermentation of the raw materials in the composting reactor and making it convenient for workers to disassemble and install.

[0014] In one or more embodiments of the present invention, a feeding hopper is fixedly connected to the top end of the feeding pipe for convenient feeding and reducing spillage of raw wood chips. A lower limit ring and an upper limit ring are fixed on the feeding pipe for limiting the feeding pipe, so that the feeding pipe can slide up and down, but cannot disengage from the sliding support plate. The bottom of the sliding support plate is chiseled with a limit ring groove that matches the lower limit ring, so that the lower limit ring can be easily engaged, thereby facilitating the sliding support plate to drive the feeding pipe to slide without being easily obstructed.

[0015] In one or more embodiments of the present invention, both ends of the sliding support plate are fixedly connected to the end cover adjustment plate with a shielding cloth, which is used to shield the raw material from splashing, to prevent the raw material from splashing out during the turning process, causing waste and polluting the surrounding environment, and also does not easily block the sliding support plate from sliding.

[0016] The end cap adjustment plate has multiple evenly distributed limiting slots. Limiting blocks are inserted into the limiting slots, and a pair of side blocks are fixed on the limiting blocks. By locking the limiting blocks in the limiting slots, one end of the limiting blocks can be inserted into the limiting groove on the limiting slider, thereby restricting the sliding of the sliding support plate. Furthermore, the side blocks prevent the limiting blocks from being inserted into the limiting groove after rotating 90 degrees, thus facilitating the sliding of the sliding support plate.

[0017] In one or more embodiments of the present invention, a pair of limiting sliders are fixedly installed on the sliding support plate to support the sliding support plate and enable the sliding support plate to slide without falling off. Each pair of limiting sliders has a limiting groove that matches the lower end of the limiting block. By locking the lower end of the limiting block in the limiting groove, the pair of limiting sliders and the sliding support plate are fixed, so that the sliding support plate can no longer slide, and thus the position of the feeding pipe will not change.

[0018] In one or more embodiments of the present invention, the end cap adjusting plate is provided with a plurality of rotating grooves, the number of which is the same as the number of limiting blocks, to provide space for the limiting ring blocks and the supporting springs. The limiting ring blocks are slidably arranged in the rotating grooves and are fixed on the limiting blocks. The limiting blocks can be driven to move, and by pushing the limiting ring blocks, one end of the limiting blocks can be tightly locked in the limiting groove. A supporting spring is fixedly connected between the limiting ring blocks and the end cap adjusting plate to push the limiting ring blocks so that the limiting blocks are less likely to shake and fall off.

[0019] The composting reactor is also provided with a discharge port, and a discharge baffle is installed inside the discharge port. The discharge baffle is threaded with fastening bolts. By removing the discharge baffle, the compost in the composting reactor can be easily taken out. By fixing the discharge baffle to the composting reactor with the fastening bolts, leakage will not occur during the composting fermentation process.

[0020] In one or more embodiments of the present invention, a drive motor is fixedly connected to one end of the transmission shaft tube outside the support base, which is used to drive the transmission shaft tube to rotate, so that the transmission shaft tube can drive multiple material turning blades and auxiliary material turning plates to rotate, thereby playing the role of material turning. Multiple air supply holes are drilled on the transmission shaft tube to allow the gas inside the transmission shaft tube to be discharged outward.

[0021] The end of the drive shaft tube away from the drive motor is rotatably connected to an air transmission frame for delivering air into the drive shaft tube. A connecting bearing is fixedly installed between the drive shaft tube and the air transmission frame so that the drive shaft tube can rotate while receiving air without being affected. An air conveying component is also installed on one side of the air transmission frame for delivering air to the raw materials, thereby providing the oxygen required for fermentation.

[0022] In one or more embodiments of the present invention, the gas delivery assembly includes: a support frame, a drive fan, and a transmission pipe; the support frame is disposed on one side of the support base, the drive fan is fixedly installed in the support frame for driving the flow of gas, and the transmission pipe is disposed between the support frame and the transmission frame for delivering the gas drawn in by the drive fan to the transmission shaft tube. The air flow is driven by starting the drive fan, and then the air is delivered to the transmission shaft tube through the transmission pipe.

[0023] In one or more embodiments of the present invention, a grid frame is fixedly installed on the support frame to perform preliminary air filtration and filter out some large impurities. A filter screen and dehumidifying cotton are also provided inside the support frame. The filter screen and dehumidifying cotton are respectively installed below and above the drive fan. The filter screen can filter out fine impurities in the air, and the dehumidifying cotton dehumidifies the air to prevent excess moisture from being brought into the raw materials in the composting reactor.

[0024] A method of using a wood chip composting device includes the following steps:

[0025] S1. First, remove a pair of sealing plates, pour sawdust composting material into the composting reactor through the feed inlet, then seal it with a pair of sealing plates, and then seal the feed hopper to allow fermentation reaction to take place in the composting reactor. During the fermentation process, by inserting a thermometer into the composting reactor through the feed pipe, the problem inside the sawdust pile can be known in real time.

[0026] S2. During the fermentation process, it may be necessary to turn the material and ventilate. At this time, remove the pair of sealing plates again, and then start the drive motor and drive fan. The drive motor drives the transmission shaft tube to rotate, and the transmission shaft tube can drive multiple turning blades and auxiliary turning plates to rotate, thereby achieving the effect of turning the raw materials and avoiding the raw materials from clumping and anaerobic conditions.

[0027] S3. After the drive fan starts, it drives the gas to flow, allowing the outside gas to be drawn in. Impurities are filtered out through the filter screen and then dehumidified through the dehumidifying cotton to avoid increasing the humidity of the raw materials. Then, it is transported to the drive shaft tube through the transmission air pipe, and then dispersed through multiple air outlets on the drive shaft tube, and then sprayed outward from multiple jet nozzles and one-way valves.

[0028] S4. The rotating turning blades and auxiliary turning blades can make the turning raw material pile come into uniform contact with oxygen. By directly introducing oxygen into the raw material and then turning the raw material, the oxygen introduction effect is improved, avoiding dead corners. Moreover, the sprayed gas also has a certain turning effect, avoiding anaerobic or clumping.

[0029] S5. Moreover, by sliding the feeding pipe, the feeding pipe can block one side of the auxiliary tilting plate, thereby allowing the auxiliary tilting plate to tilt to one side. At this time, the rotating auxiliary tilting plate not only has the function of tilting, but also assists in pushing the raw material to one side, thereby improving the tilting effect, and also plays an auxiliary role in discharging.

[0030] S6. In addition, when it is necessary to add materials midway, the raw materials are directly added into the feeding hopper and then slide down into the composting reactor through the feeding pipe. The continuous turning of the turning blade and the auxiliary turning plate can make the raw materials in the feeding pipe gradually slide into the composting reactor, achieving the effect of directly adding them into the raw materials. After fermentation is completed, the compost can be easily removed by removing the discharge baffle.

[0031] Compared with existing technologies, this invention, through its design, enables the sawdust to be turned regularly during the composting process, improving the turning effect and preventing the formation of an anaerobic environment inside the compost pile. This ensures that the decomposition efficiency of the sawdust is not affected and the quality of the organic fertilizer is not reduced. Furthermore, it facilitates the addition of raw materials to the compost pile midway through the process, improving the mixing efficiency and effect of the raw materials and the compost pile and avoiding unevenness.

Detailed Implementation

[0046] To enable those skilled in the art to better understand the technical solutions in this disclosure, the technical solutions in the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments in this disclosure, all other embodiments obtained by those skilled in the art without creative effort should fall within the scope of protection of this disclosure.

[0047] like Figures 1 to 11 As shown, a wood chip composting device according to one embodiment of the present invention includes: a support base 1, a support reaction component 2, a turning and mixing mechanism 3, and an auxiliary turning mechanism 4.

[0048] like Figures 1 to 11 As shown, the supporting reaction assembly 2 is installed on the supporting base 1. The supporting reaction assembly 2 includes a composting reactor 201, an end cover adjusting plate 204, a sliding support plate 205, and a feeding pipe 206. The end cover adjusting plate 204 is fixed on the composting reactor 201, the sliding support plate 205 is slidably disposed on the end cover adjusting plate 204, and the feeding pipe 206 is slidably inserted into the sliding support plate 205. The turning and mixing mechanism 3 is installed inside the composting reactor 201. The turning and mixing mechanism 3 includes a drive shaft tube 301 and multiple turning blades 302. Both ends of the drive shaft tube 301 are fixedly connected to the composting reactor 201 with supporting bearings 305. Multiple turning blades 302 are all installed on the drive shaft tube 301, and each of the multiple turning blades 302 has an air jet 303 cut out.

[0049] In addition, an auxiliary turning mechanism 4 is installed on the drive shaft tube 301. The auxiliary turning mechanism 4 is used to turn the sawdust fertilizer in the composting reactor 201, and can also help control the turning direction of the sawdust. The auxiliary turning mechanism 4 includes a fixed ring tube 404 and multiple auxiliary turning plates 401. The fixed ring tube 404 is fixed to the drive shaft tube 301, and multiple gas supply connecting pipes 406 are rotatably installed on the fixed ring tube 404. The auxiliary turning plates 401 are fixed to the other end of the gas supply connecting pipes 406. A dispersion chamber 402 is cut into the auxiliary turning plate 401, and the gas supply connecting pipes 406 are connected to the dispersion chambers 402. Multiple one-way valves 403 are also installed on the auxiliary turning plate 401. A tight connecting sleeve 405 is fixedly connected between the fixed ring tube 404 and the gas supply connecting pipes 406, so that the gas supply connecting pipes 406 can rotate. However, due to the tight connection, when not blocked by the feeding pipe 206, it only turns the raw materials without causing rotation.

[0050] like Figures 1 to 6As shown, the composting reactor 201 has a pair of feed inlets 202 for easy pouring of composting materials into the reactor 201, facilitating operation and allowing ventilation to allow oxygen to enter during material turning. A sealing plate 207 is installed on the pair of feed inlets 202 to seal them, thus facilitating fermentation of the materials inside the composting reactor 201 and making disassembly and installation easier for workers.

[0051] like Figures 1 to 9 As shown, a feeding hopper 208 is fixedly connected to the top of the feeding pipe 206 for convenient feeding and to reduce spillage of raw wood chips. A lower limiting ring 209 and an upper limiting ring 210 are fixed to the feeding pipe 206 to limit its movement, allowing it to slide up and down without disengaging from the sliding support plate 205. A limiting ring groove 211 matching the lower limiting ring 209 is cut into the bottom of the sliding support plate 205, facilitating the insertion of the lower limiting ring 209 and enabling the sliding support plate 205 to drive the feeding pipe 206 to slide smoothly without obstruction.

[0052] like Figures 1 to 5 As shown, both ends of the sliding support plate 205 are fixedly connected to the end cover adjustment plate 204 with shielding cloth 212, which is used to shield the raw material from splashing, prevent the raw material from splashing out during the turning process, causing waste and polluting the surrounding environment, and also does not easily block the sliding of the sliding support plate 205.

[0053] like Figures 1 to 5 As shown, the end cap adjusting plate 204 has multiple evenly distributed limiting slots 213. Limiting blocks 214 are inserted into the limiting slots 213, and a pair of side blocks 215 are fixed to the limiting blocks 214. By engaging the limiting blocks 214 within the limiting slots 213, one end of the limiting blocks 214 can be inserted into the limiting grooves 217 on the limiting slider 216, thus restricting the sliding of the sliding support plate 205. Furthermore, the side blocks 215 prevent the limiting blocks 214 from being inserted into the limiting grooves 217 after rotating 90 degrees, thereby facilitating the sliding of the sliding support plate 205.

[0054] like Figures 1 to 8 As shown, a pair of limiting sliders 216 are fixedly installed on the sliding support plate 205 to support the sliding support plate 205 and prevent it from sliding off. Each pair of limiting sliders 216 has a limiting groove 217 that matches the lower end of the limiting block 214. By engaging the lower end of the limiting block 214 within the limiting groove 217, the pair of limiting sliders 216 and the sliding support plate 205 are fixed, preventing the sliding support plate 205 from sliding further and thus ensuring that the position of the feeding pipe 206 remains unchanged.

[0055] like Figures 1 to 8 As shown, the end cap adjusting plate 204 has multiple rotating grooves, the same number as the limiting blocks 214, providing space for the limiting ring block 218 and the support spring 219. The limiting ring block 218 is slidably disposed in the rotating groove and is fixed to the limiting block 214. The limiting block 214 can drive the limiting ring block 218 to move, and pushing the limiting ring block 218 can also make one end of the limiting block 214 tightly locked in the limiting groove 217. A support spring 219 is fixedly connected between the limiting ring block 218 and the end cap adjusting plate 204 to push the limiting ring block 218 so that the limiting block 214 is less likely to shake and fall off.

[0056] like Figures 1 to 6 As shown, a discharge port is also cut into the composting reactor 201, and a discharge baffle 220 is installed inside the discharge port. The discharge baffle 220 is threaded with a fastening bolt 203. By removing the discharge baffle 220, the compost in the composting reactor 201 can be easily taken out. And by fixing the discharge baffle 220 to the composting reactor 201 with the fastening bolt 203, there will be no leakage during the composting fermentation process.

[0057] like Figures 1 to 10 As shown, a drive motor 304 is fixedly connected to one end of the drive shaft tube 301 outside the support base 1. This motor drives the drive shaft tube 301 to rotate, enabling it to rotate multiple material-turning blades 302 and auxiliary material-turning plates 401, thus achieving the function of material turning. Multiple air outlets 306 are drilled on the drive shaft tube 301 to allow gas inside the drive shaft tube 301 to be discharged outwards.

[0058] like Figures 1 to 4 As shown, an air-transmitting frame 307 is rotatably connected to the end of the drive shaft tube 301 away from the drive motor 304, for delivering air into the drive shaft tube 301. A connecting bearing 308 is fixedly installed between the drive shaft tube 301 and the air-transmitting frame 307, so that the rotation of the drive shaft tube 301 is not affected while receiving air. An air-transmitting assembly 309 is also installed on one side of the air-transmitting frame 307 for delivering air to the raw materials, thereby providing the oxygen required for fermentation.

[0059] like Figures 1 to 4As shown, the gas delivery assembly 309 includes a support frame 310, a drive fan 314, and a transmission pipe 311. The support frame 310 is located on one side of the support base 1; the drive fan 314 is fixedly installed inside the support frame 310 and is used to drive the flow of gas. The transmission pipe 311 is located between the support frame 310 and the gas delivery frame 307, and is used to deliver the gas drawn in by the drive fan 314 into the drive shaft pipe 301. The air flow is driven by the start of the drive fan 314, and then the air is delivered into the drive shaft pipe 301 through the transmission pipe 311.

[0060] Specifically, a mesh frame 312 is fixedly installed on the support frame 310 to perform preliminary air filtration, removing some large impurities. A filter screen 313 and dehumidifying cotton 315 are also installed inside the support frame 310. The filter screen 313 and dehumidifying cotton 315 are installed below and above the drive fan 314, respectively. The filter screen 313 filters out fine impurities from the air, and the dehumidifying cotton 315 dehumidifies the air, preventing excess moisture from being carried into the raw materials inside the composting reactor 201.

[0061] A method of using a wood chip composting device includes the following steps:

[0062] S1. First, remove a pair of sealing plates 207, pour sawdust composting raw materials into the composting reactor 201 through the feed inlet 202, then seal it with a pair of sealing plates 207, and then seal the feed hopper 208 to allow fermentation reaction to take place in the composting reactor 201. During the fermentation process, by inserting a thermometer into the composting reactor 201 through the feed pipe 206, the problems inside the sawdust pile can be known in real time.

[0063] S2. During the fermentation process, it may be necessary to turn the material and ventilate. At this time, remove the pair of sealing plates 207 again, and then start the drive motor 304 and drive fan 314. The drive motor 304 drives the transmission shaft tube 301 to rotate, and the transmission shaft tube 301 can drive multiple turning blades 302 and auxiliary turning plates 401 to rotate, thereby achieving the effect of turning the raw materials and avoiding the clumping and anaerobic conditions of the raw materials.

[0064] S3. After the drive fan 314 starts, it drives the gas to flow, allowing the outside gas to be drawn in. The impurities are filtered out by the filter screen 313 and then dehumidified by the dehumidifying cotton 315 to avoid increasing the humidity of the raw materials. Then, it is transported to the drive shaft tube 301 through the transmission air pipe 311, and then dispersed through multiple air outlets 306 on the drive shaft tube 301, and then sprayed outward from multiple jet elements 303 and one-way valve 403.

[0065] S4. The rotating turning blade 302 and auxiliary turning blade 401 can make the turning raw material pile come into uniform contact with oxygen. By directly introducing oxygen into the raw material and then turning the raw material, the oxygen introduction effect is improved, avoiding dead corners. Moreover, the sprayed gas also has a certain turning effect, avoiding anaerobic or clumping.

[0066] S5. Moreover, by sliding the feeding pipe 206, the feeding pipe 206 can block one side of the auxiliary tilting plate 401, thereby allowing the auxiliary tilting plate 401 to tilt to one side. At this time, the rotating auxiliary tilting plate 401 not only has the function of tilting, but also assists in pushing the raw material to one side, thereby improving the tilting effect, and can also play an auxiliary role when discharging.

[0067] S6. In addition, when it is necessary to add materials midway, the raw materials are directly added into the feeding hopper 208, and then slide down into the composting reactor 201 through the feeding pipe 206. The continuous turning of the turning blade 302 and the auxiliary turning plate 401 can make the raw materials in the feeding pipe 206 gradually slide into the composting reactor 201, achieving the effect of directly adding the raw materials into the interior. After fermentation is completed, the compost can be easily removed by removing the discharge baffle 220.

10. A method of using a wood chip composting device according to any one of claims 1-9, characterized in that, Includes the following steps: S1. First, remove a pair of sealing plates, pour sawdust composting material into the composting reactor through the feed inlet, then seal it with a pair of sealing plates, and then seal the feed hopper to allow fermentation reaction to take place in the composting reactor. During the fermentation process, by inserting a thermometer into the composting reactor through the feed pipe, the problem inside the sawdust pile can be known in real time. S2. During the fermentation process, it may be necessary to turn the material and ventilate. At this time, remove the pair of sealing plates again, and then start the drive motor and drive fan. The drive motor drives the transmission shaft tube to rotate, and the transmission shaft tube can drive multiple turning blades and auxiliary turning plates to rotate, thereby achieving the effect of turning the raw materials and avoiding the raw materials from clumping and anaerobic conditions. S3. After the drive fan starts, it drives the gas to flow, allowing the outside gas to be drawn in. Impurities are filtered out through the filter screen and then dehumidified through the dehumidifying cotton to avoid increasing the humidity of the raw materials. Then, it is transported to the drive shaft tube through the transmission air pipe, and then dispersed through multiple air outlets on the drive shaft tube, and then sprayed outward from multiple jet nozzles and one-way valves. S4. The rotating turning blades and auxiliary turning blades can make the turning raw material pile come into uniform contact with oxygen. By directly introducing oxygen into the raw material and then turning the raw material, the oxygen introduction effect is improved, avoiding dead corners. Moreover, the sprayed gas also has a certain turning effect, avoiding anaerobic or clumping. S5. Moreover, by sliding the feeding pipe, the feeding pipe can block one side of the auxiliary tilting plate, thereby allowing the auxiliary tilting plate to tilt to one side. At this time, the rotating auxiliary tilting plate not only has the function of tilting, but also assists in pushing the raw material to one side, thereby improving the tilting effect, and also plays an auxiliary role in discharging. S6. In addition, when it is necessary to add materials midway, the raw materials are directly added into the feeding hopper and then slide down into the composting reactor through the feeding pipe. The continuous turning of the turning blade and the auxiliary turning plate can make the raw materials in the feeding pipe gradually slide into the composting reactor, achieving the effect of directly adding them into the raw materials. After fermentation is completed, the compost can be easily removed by removing the discharge baffle.
