Technical Field
[0001] This utility model belongs to the field of wood waste recycling and treatment technology, and in particular relates to a centralized recycling device for wood processing waste. Background Technology
[0002] Centralized recycling of wood processing waste involves the unified collection and sorting of waste generated during wood processing, such as scraps, sawdust, shavings, and bark, and its recycling to improve resource utilization and reduce environmental pollution. These wastes can be used to produce engineered wood products, biomass fuels, paper, and wood-plastic composites, achieving waste reuse and promoting green and sustainable development. Centralized recycling not only reduces wood waste but also lowers production costs and improves economic efficiency for businesses.
[0003] Traditional wood crushing devices, due to their open-type inlet design and the airflow disturbance caused by the high-speed rotating blades or hammers during crushing, cause fine wood chips to escape from the inlet with the airflow, resulting in dust filling the working environment, affecting the health of operators, and potentially causing safety hazards. Utility Model Content
[0004] In view of the problems existing in the prior art, this utility model provides a centralized recycling device for wood processing waste.
[0005] This utility model is implemented as follows: a centralized recycling device for wood processing waste includes a support frame and a recycling box fixed on the upper part of the support frame; a crushing roller rotatably installed inside the recycling box, which crushes and recycles the input wood waste when it rotates; a dust suppression component connected to an external water source to spray and absorb the wood chips generated from the crushed wood waste to suppress dust, wherein the dust suppression component includes a hollow plate fixed on the upper part of the recycling box, a transmission plate slidably installed inside the hollow plate, and a plurality of spray gaps opened on the side of the transmission plate near the input port of the recycling box; and a control plate fixedly installed on the lower part of the support frame, which electromagnetically controls the transmission plate to extend and retract and changes the extension distance of the spray gaps.
[0006] In a preferred embodiment of this utility model, the output end of the motor fixed on one side of the support frame is fixedly connected to the input end of the gearbox fixed on the upper part of the support frame. The motor is electrically connected to the control board. Two crushing rollers are provided. One of the crushing rollers is fixedly connected to the output end of the gearbox. One end of each of the two crushing rollers passes through the recycling box and is fixedly connected to a gear. The two gears are meshed and connected. A cover fixed on one side of the support frame movably covers the two gears.
[0007] In a preferred embodiment of this invention, an electromagnet electrically connected to the control board is fixedly installed on the upper part of the hollow plate, and an armature is fixedly installed on the transmission plate at a position corresponding to the electromagnet. The armature and the electromagnet are connected by a spring. When the electromagnet is energized, the armature is magnetically attracted, controlling the transmission plate to extend outward.
[0008] In a preferred embodiment of this invention, the hollow plate has a first through hole, and the transmission plate has a second through hole. The length of the second through hole is greater than that of the first through hole, and when the transmission plate is moved in a controlled manner, the second through hole is always connected to the first through hole.
[0009] As a preferred embodiment of the present invention, the recycling device is further provided with a transmission component, the transmission component including a turntable fixed to the outside of one of the gears, a connecting rod rotatably mounted on the outside of the turntable, an air cylinder output end fixed to the inside of the cover being rotatably connected to the connecting rod, two air cylinders being provided, the two air cylinder output ends being fixedly connected to the same linkage plate, the linkage plate being rotatably connected to the connecting rod.
[0010] In a preferred embodiment of this invention, one of the air cylinders has an input end that is connected to the outside, while the other air cylinder is used to connect to a water source.
[0011] In a preferred embodiment of this invention, each air cylinder output end is fixedly connected to a flow divider plate, and two hollow plates are provided. Each hollow plate input end is fixedly installed with a tee. The two output ends of the flow divider plate of one air cylinder are respectively connected to one input end of the two tee plates. The two output ends of the flow divider plate of the air cylinder connected to the water source are respectively connected to the other input end of the two tee plates. The transmission plate inside the hollow plate receives the gas and liquid transmitted by the tee plates and performs a spraying action. During transmission, the air cylinder is connected to the tee plates through a transmission pipe.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] When wood waste is put into the recycling bin, the crushing roller starts to rotate, crushing and recycling the waste. During this process, the high-speed rotation and shearing action generates a large amount of fine wood chips and dust. Traditional devices allow dust to escape because the inlet is open. This device, however, uses a dust-suppressing component for spray adsorption, effectively suppressing dust diffusion. The dust-suppressing component includes a hollow plate fixed to the upper part of the recycling bin. A conveyor plate is slidably installed inside the hollow plate. Multiple spray gaps are provided on the side of the conveyor plate near the inlet. A control plate electromagnetically controls the extension and retraction of the conveyor plate, thereby adjusting the extension of the spray gaps. The system adjusts the distance and dynamically changes the water output to match the spray density with the dust concentration. This creates a water mist covering the wood chips the instant they are generated, causing the dust particles to become heavier and settle quickly, preventing them from remaining suspended in the air. Simultaneously, the moistened wood chips after spraying are more easily drawn into the recycling bin and are not carried out by airflow disturbances, fundamentally reducing dust escape from the inlet. Furthermore, the telescopic adjustment function of the conveyor plate allows for flexible adjustment based on the crushing intensity and dust volume of different wood wastes, ensuring the device maintains high-efficiency dust reduction under various operating conditions. Ultimately, this significantly improves the working environment and enhances production safety. Attached Figure Description

[0022] To further understand the utility model content, features and effects of this utility model, the following embodiments are provided, and detailed descriptions are given in conjunction with the accompanying drawings.
[0023] The structure of this utility model will now be described in detail with reference to the accompanying drawings.
[0024] like Figures 1 to 5 As shown, this utility model embodiment provides a centralized recycling device for wood processing waste, including a support frame 1, and further including: a recycling box 4 fixed on the upper part of the support frame 1; a crushing roller 5 rotatably installed inside the recycling box 4, which crushes and recycles the input wood waste when it rotates; a dust suppression component 7, which is connected to an external water source to spray and absorb the remaining wood chips from the crushed wood waste to suppress dust. The dust suppression component 7 includes a hollow plate 701 fixed on the upper part of the recycling box 4, a transmission plate 702 slidably installed inside the hollow plate 701, and a plurality of spray gaps 703 opened on the side of the transmission plate 702 near the input port of the recycling box 4; and a control plate fixedly installed on the lower part of the support frame 1, which electromagnetically controls the transmission plate 702 to extend and retract, and changes the extension distance of the spray gaps 703.
[0025] In the aforementioned centralized recycling device for wood processing waste, after the wood waste is put into the recycling bin 4, the crushing roller 5 starts to rotate to crush and recycle the waste. At this time, due to the high-speed rotational shearing action during the crushing process, a large amount of fine wood chips and dust will be generated. Traditional devices cause dust to escape because the inlet is open. However, this device effectively suppresses dust diffusion by setting up a dust suppression component 7 for spray adsorption. The dust suppression component 7 includes a hollow plate 701 fixed to the upper part of the recycling bin 4. A transmission plate 702 is slidably installed inside the hollow plate 701. The transmission plate 702 has multiple spray gaps 703 on the side near the inlet. The control plate controls the extension and retraction of the transmission plate 702 through electromagnetic control. The spray mechanism adjusts the extension distance of the spray gap 703 and dynamically changes the water output to match the spray density with the dust concentration. This creates a water mist covering the wood chips instantly, causing the dust particles to become heavier and settle quickly due to the moisture, preventing dust from suspending in the air. Simultaneously, the moistened wood chips after spraying are more easily drawn into the recycling bin 4 and are not carried out by airflow disturbances, fundamentally reducing dust escape from the inlet. Furthermore, the telescopic adjustment function of the transmission plate 702 can be flexibly adjusted according to the crushing intensity and dust volume of different wood waste materials, ensuring the device maintains high-efficiency dust reduction under different operating conditions, ultimately significantly improving the working environment and enhancing production safety.
[0026] In this embodiment, the output end of the motor 2 fixed on one side of the support frame 1 is fixedly connected to the input end of the gearbox 3 fixed on the upper part of the support frame 1. The motor 2 is electrically connected to the control board. There are two crushing rollers 5. One of the crushing rollers 5 is fixedly connected to the output end of the gearbox 3. One end of each of the two crushing rollers 5 passes through the recycling box 4 and is fixedly connected to a gear 9. The two gears 9 are meshed and connected. The cover 6 fixed on one side of the support frame 1 can be moved to cover the two gears 9.
[0027] The motor 2 is fixed on one side of the support frame 1, and its output end is fixedly connected to the input end of the gearbox 3. When the motor 2 is powered on, the driving force is transmitted to the crushing roller 5 after being adjusted by the gearbox 3. Since there are two crushing rollers 5, the output end of the gearbox 3 is fixedly connected to one of the crushing rollers 5, so that it first obtains power to rotate. At the same time, one end of the crushing roller 5 passes through the recycling box 4 and is connected to the gear 9 fixed thereon. The other crushing roller 5 is also connected to the gear 9. The two mesh with each other, so that the second crushing roller 5 rotates synchronously in the opposite direction. During the crushing process, the two crushing rollers 5 move towards each other, squeezing, shearing and tearing the input wood waste into small pieces, thereby improving the crushing efficiency.
[0028] Meanwhile, to prevent safety hazards or dust accumulation during the high-speed rotation of gear 9, and to prevent accidental injury to operators or damage to equipment caused by foreign objects entering the gear 9 during rotation, a cover 6 is installed on one side of the support frame 1 to cover gear 9 and provide protection.
[0029] In this embodiment, an electromagnet 708 electrically connected to a control board is fixedly installed on the upper part of the hollow plate 701. An armature 705 is fixedly installed on the transmission plate 702 at the corresponding position of the electromagnet 708. The armature 705 and the electromagnet 708 are connected by a spring. When the electromagnet 708 is energized, the armature 705 is magnetically attracted, controlling the transmission plate 702 to extend outward. The hollow plate 701 has a first through hole 706, and the transmission plate 702 has a second through hole 707. The length of the second through hole 707 is greater than that of the first through hole 706. When the transmission plate 702 is moved under control, the second through hole 707 is always connected to the first through hole 706.
[0030] An electromagnet 708 is fixedly mounted on the upper part of the hollow plate 701 and is electrically connected to the control board. An armature 705 is fixedly mounted on the transmission plate 702 at a position corresponding to the electromagnet 708. The two are connected by a spring, so that the transmission plate 702 maintains its initial position when no external force is applied. When the electromagnet 708 is energized, it generates a magnetic force to attract the armature 705, overcoming the spring's restoring force, causing the transmission plate 702 to extend outward and adjust the opening of the spray gap 703.
[0031] The hollow plate 701 is provided with a first through hole 706, and the transmission plate 702 is provided with a second through hole 707 with a length greater than the first through hole 706, so that when the transmission plate 702 moves in a controlled manner, the second through hole 707 is always connected to the first through hole 706, so that the water mist can be sprayed out smoothly.
[0032] By controlling the on / off state of the electromagnet 708, the position of the transmission plate 702 can be precisely adjusted, thereby changing the opening of the spray gap 703. This enables the adjustment of the water mist coverage area and flow rate under different working conditions, improving dust suppression efficiency while reducing unnecessary water mist waste, making the dust suppression process more intelligent and efficient.
[0033] In this embodiment, the recycling device is further provided with a transmission component 8. The transmission component 8 includes a turntable 801 fixed to the outside of one of the gears 9. A connecting rod 802 is rotatably mounted on the outside of the turntable 801. The output end of an air cylinder 804 fixed inside the cover 6 is rotatably connected to the connecting rod 802. There are two air cylinders 804. The output ends of the two air cylinders 804 are fixedly connected to the same linkage plate 803. The linkage plate 803 is rotatably connected to the connecting rod 802.
[0034] When the crushing roller 5 rotates, the gear 9 rotates accordingly, thereby driving the externally fixed turntable 801 to rotate synchronously. A connecting rod 802 is rotatably mounted on the outside of the turntable 801. One end of the connecting rod 802 is connected to the turntable 801, and the other end is rotatably connected to the output end of the air cylinder 804 fixed inside the cover 6. At the same time, there are two air cylinders 804 on the device. The output ends of the two air cylinders 804 are fixedly connected to the same linkage plate 803, and the linkage plate 803 is also rotatably connected to the connecting rod 802.
[0035] When the crushing roller 5 rotates and drives the gear 9 to rotate, the turntable 801 rotates accordingly, pushing the connecting rod 802 to perform periodic reciprocating motion, thereby driving the output end of the air cylinder 804 to extend and retract, causing the linkage plate 803 to move accordingly, thus realizing the dynamic drive of the air cylinder 804.
[0036] In this embodiment, one air cylinder 804 has its input end connected to the outside, and the other air cylinder 804 is used to connect to a water source. Each air cylinder 804 has a diverter plate 805 fixedly connected to its output end. There are two hollow plates 701, and each hollow plate 701 has a tee 704 fixedly installed at its input end. The two output ends of the diverter plate 805 of one air cylinder 804 are respectively connected to one input end of the two tee 704s. The two output ends of the diverter plate 805 of the air cylinder 804 connected to the water source are respectively connected to the other input end of the two tee 704s. The transmission plate 702 inside the hollow plate 701 receives the gas and liquid transmitted by the tee 704 and performs a spray action. During transmission, the air cylinder 804 is connected to the tee 704 through the transmission pipe 806.
[0037] The rotation of the crushing roller 5 drives the transmission assembly 8, enabling the two air cylinders 804 to work together, intermittently spraying air or water, thereby forming a wave-shaped water mist on the upper part of the recycling box 4.
[0038] The rotation of the crushing roller 5 drives the gear 9 to rotate, which in turn drives the turntable 801 to rotate synchronously, pushing the connecting rod 802 and the linkage plate 803 to move, and finally driving the air cylinder 804 to work. The input end of one air cylinder 804 is connected to the outside and is responsible for drawing in air, while the other air cylinder 804 is connected to a water source for conveying liquid. The output ends of the two air cylinders 804 are connected to two three-way valves 704 through the diverter plate 805. Gas and liquid enter the hollow plate 701 through the three-way valves 704 respectively.
[0039] During the transmission process, gas and liquid are transported to hollow plate 701 through transmission pipe 806. After receiving gas and liquid, transmission plate 702 forms a gas-filled spray. Air cylinder 804 works intermittently, so that the water mist sprayed by transmission plate 702 spreads in a wave shape on the upper part of recycling box 4, evenly covering the crushing area, effectively suppressing dust diffusion, improving dust reduction effect, and optimizing the safety and cleanliness of the working environment.
[0040] The working principle of this utility model:
[0041] When wood waste is put into the recycling bin 4, the crushing roller 5 starts to rotate to crush and recycle the waste. At this time, due to the high-speed rotation and shearing action during the crushing process, a large amount of fine wood chips and dust will be generated. Traditional devices cause dust to escape because the inlet is open. However, this device effectively suppresses dust diffusion by setting up a dust suppression component 7 for spray adsorption. The dust suppression component 7 includes a hollow plate 701 fixed to the upper part of the recycling bin 4. A conveyor plate 702 is slidably installed inside the hollow plate 701. The conveyor plate 702 has multiple spray gaps 703 on the side near the inlet. The control plate controls the extension of the conveyor plate 702 through electromagnetic control. The retraction action adjusts the extension distance of the spray gap 703 and dynamically changes the water output to match the spray density with the dust concentration. Water mist is formed the instant the wood chips are generated, causing the dust particles to become heavier due to the humidification effect and settle quickly, preventing the dust from being suspended in the air. At the same time, the wet wood chips after spraying are easier to enter the recycling bin 4 and will not be carried out by airflow disturbance, fundamentally reducing the dust escape from the inlet. In addition, the telescopic adjustment function of the transmission plate 702 can be flexibly adjusted according to the crushing intensity and dust amount of different wood wastes, so that the device can maintain a high efficiency dust reduction effect under different working conditions.
