Description

Technical Field

[0001] This invention relates to the pretreatment of wood chips, and more particularly to a wood peeling and waste removal production line. Background Technology

[0002] The manufacturing process of particleboard includes wood shavings, shaving drying, shaving mixing with glue, shaving laying, and pressing into boards. Large timber is the best choice for particleboard, but the exclusive use of large timber significantly increases the cost for particleboard manufacturers.

[0003] In addition, it has been found that when bark chips, bark flakes, and / or soil and gravel are mixed into the wood shavings, the strength of the particleboard is significantly reduced, which is particularly noticeable when the smallest timber is used as the main raw material for particleboard.

[0004] Therefore, it is necessary to pre-treat the wood by peeling and removing waste before shaving it. Summary of the Invention

[0005] This invention aims to solve at least one of the aforementioned technical problems by providing a wood peeling and waste removal production line that can pre-treat wood by peeling and waste removal, improve the quality and strength of particleboard, facilitate the substantial application of small timber as the main raw material for particleboard, reduce the cost of particleboard production enterprises, make environmentally friendly use of small timber, avoid the waste of burning small timber, and improve the utilization rate of trees.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A timber peeling and waste removal production line includes:

[0008] A bark peeling device includes a groove, a peeling roller, and a peeling motor that is driven to the peeling roller. The groove is adapted to be inclined, and one or more working openings are opened in the groove of the groove. The higher end of the groove is adapted to insert wood. The peeling roller corresponds to each working opening. The two ends of the peeling roller are rotatably connected to the groove. The peeling roller extends axially along the groove, and part of the peripheral wall of the peeling roller protrudes into the groove through the working opening.

The second transmission mechanism includes a plurality of spaced-apart conveying rollers and a second conveying motor that is drively connected to the conveying rollers. The spray mechanism is located above the plurality of conveying rollers and is adapted to spray water toward the plurality of conveying rollers. A first impurity discharge port is formed between two adjacent conveying rollers. A second impurity discharge port is provided between the input end of the third transmission mechanism and the output end of the second transmission mechanism. The waste collection and discharge trough is located below the first and second impurity discharge ports.

[0010] Compared with existing technologies, the beneficial effects of this application include: the differential rotation of the wood and the peeling roller, which combines the rolling characteristics of the wood, utilizes the peeling roller to scrape off the bark, resulting in multiple points of scraping along the circumference of the wood, allowing for more thorough and rapid peeling during rolling; the groove is set at a certain inclination, allowing the wood to move synchronously during scraping, resulting in multiple points of scraping along the axial direction, allowing for more thorough and rapid peeling during movement; the detached bark can be crushed by the rolling wood and / or scraped by the peeling claws, breaking the bark into fragments, which then fall through the slag discharge gap, with the bark fragments discharged on the discharge side. To improve the efficiency of the peeling device; the trough can simultaneously accommodate multiple pieces of wood, which can rub against each other during tumbling to peel off residual small pieces of bark; the peeled wood can remove surface dirt and sand particles, avoiding damage to the shaving blades and preventing dirt and sand particles from being mixed into the shavings, effectively reducing the shavings impurity and improving the quality and strength of the particleboard; the wood can be peeled and waste removed, and the particleboard derived from this wood is of higher quality and strength, making it convenient to use small timber as the main raw material for particleboard, reducing the raw material cost of enterprises, making environmentally friendly use of small timber, avoiding the waste of small timber by burning, and improving the utilization rate of trees.

[0011] As an improvement to the above technical solution, the peeling rollers are classified into stacking peeling rollers and counterweight peeling rollers that are higher than the stacking peeling rollers. The circumferential high point of the counterweight peeling roller corresponds to one side wall of the groove. The stacking peeling roller is closer to the other side wall of the groove than the counterweight peeling roller. The stacking peeling roller and the counterweight peeling roller are adapted to form a wood stacking and tumbling zone. The side wall of the groove and the counterweight peeling roller are adapted to limit the wood, so that the wood floats and tumbles.

[0012] As an improvement to the above technical solution, the peeling roller includes a mandrel and a roller. The peeling claws are disposed on the outer peripheral wall of the roller. The mandrel passes through the roller. One end of the mandrel is integrally formed with a flange suitable for screw connection to one end of the roller. An opening is provided at the bottom of the groove. A slide is detachably connected to the groove seat and divides the opening into two working ports. The opening is suitable for the roller to be inserted into the groove seat. One end of the mandrel is connected to the groove seat through an end cap.

The spiral line extends spirally along the axial direction of the peeling roller, and all the peeling claws are divided into an even number of peeling claw groups. The even number of peeling claw groups are arranged at intervals along the circumference of the peeling roller, and a single peeling claw group is provided with multiple peeling claws at intervals along the axial direction of the peeling roller.

[0015] As an improvement to the above technical solution, the trough seat is integrally formed with the trough chamber and the slag discharge hopper. The slag discharge hopper is located below the trough chamber and the peeling roller. A maintenance window is provided between the lower end of the side wall of the trough chamber and the slag discharge hopper. The maintenance window is suitable for detaching and installing the peeling claws on the peeling roller. The trough seat is detachably connected with a protective plate. The protective plate is suitable for covering the maintenance window, and the protective plate extends upward from the side wall of the slag discharge hopper.

[0016] As an improvement to the above technical solution, the higher end of the groove is provided with a feeding ramp suitable for wood to roll in. The feeding ramp is provided with multiple bark-cutting blades, which are spaced apart and arranged side by side along the extension direction of the feeding ramp. The bark-cutting blades are suitable for biting and cutting the bark of the wood that rolls off the feeding ramp, so that the bark of the wood is divided into multiple pieces along the circumference by peeling claws.

[0017] As an improvement to the above technical solution, the sewage collection and discharge trough extends obliquely along its discharge direction, and the discharge direction of the sewage collection and discharge trough segment located directly below the second transmission mechanism is opposite to the transmission direction of the second transmission mechanism.

[0035] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0036] Reference Figures 1 to 4 , Figure 7 This invention provides a wood peeling and waste removal production line, comprising:

[0037] The peeling device 100 includes a groove 110, a peeling roller 120, and a peeling motor that is connected to the peeling roller 120. The groove 110 is adapted to be inclined. The groove 111 of the groove 110 has one or more working openings 111a. The higher end of the groove 111 is adapted to insert wood. The peeling roller 120 corresponds to the working openings 111a one by one. The two ends of the peeling roller 120 are rotatably connected to the groove 110. The peeling roller 120 extends along the axial direction of the groove 111, and part of the peripheral wall of the peeling roller 120 protrudes into the groove 111 through the working openings 111a. The peripheral wall of the peeling roller 120 is provided with multiple peeling claws 123. The peeling roller 120 has multiple peeling claws 123 arranged along the axial direction. The peeling claws 123 are adapted to scrape the bark off the wood. A slag discharge gap is provided between the side wall of the working opening 111a and the outer peripheral wall of the peeling roller 120.

[0038] The spraying and waste removal device 200 includes a frame 210, a first transmission mechanism 220, a second transmission mechanism 230, a spraying mechanism 240, a third transmission mechanism 250, and a waste collection and discharge tank 260. The frame 210 is provided with a transmission channel 211 with an open bottom. The first transmission mechanism 220, the second transmission mechanism 230, and the third transmission mechanism 250 are arranged sequentially along the conveying direction of the transmission channel 211. The input end of the first transmission mechanism 220 is adapted to receive the wood that emerges from the lower end of the tank 111. The second transmission mechanism 230 includes multiple inter-channels... The conveying rollers 231 are arranged side by side, and the second conveying motor 232 is connected to the conveying rollers 231. The spraying mechanism 240 is arranged above the multiple conveying rollers 231. The spraying mechanism 240 is adapted to spray water toward the multiple conveying rollers 231. A first impurity drop outlet 233 is formed between two adjacent conveying rollers 231. A second impurity drop outlet 234 is provided between the input end of the third transmission mechanism 250 and the output end of the second transmission mechanism 230. The sludge collection and discharge tank 260 is arranged below the first impurity drop outlet 233 and the second impurity drop outlet 234.

[0039] Reference Figure 2 , Figure 3 The peeling roller 120 extends axially along the groove seat 110, meaning the peeling roller 120 coincides with or is parallel to the axis of the groove seat 110. In the method of use of this invention, when the wood is placed into the groove 111, the wood can follow the axial direction of the groove 111, so that the time the wood spends in the groove 111 is fully utilized for peeling. The groove seat 110 is inclined, making its groove 111 inclined, which facilitates the synchronous movement of the wood during the peeling process and realizes the transfer of the wood; the peeling roller 120 is adapted to the groove 111, and the peeling roller 120 is also inclined, with the axis of both the peeling roller 120 and the groove 111 being suitable for an inclined arrangement relative to the horizontal plane.

[0040] Understandably, due to its own weight and the friction between the wood and the inner wall of the groove 111, the rolling speed of the wood is not synchronized with that of the peeling roller 120, and the peeling claws 123 are suitable for scraping off the bark of the wood. Understandably, in the method of use of the present invention, the rotation direction of the peeling roller 120 causes the peeling side of the peeling claws 123 to face the outer wall of the wood. The peeling motor can be an electric motor (electric motor) or a hydraulic motor.

[0041] The width of the transmission channel 211 is less than the length of the wood, so that the wood is transported in the transmission channel 211 in a shifting manner.

[0042] An equivalent arrangement can be understood, in which the first transmission mechanism 220, the second transmission mechanism 230 and the third transmission mechanism 250 are each provided with a bracket and a sub-channel, the sub-channels are connected in series to form a transmission channel 211, and the rack 210 is decomposed into multiple such brackets.

[0043] It is understood that the input end of the first transmission mechanism 220 is the starting end of the spray waste removal device 200, which is suitable for receiving peeled wood. The multiple conveying rollers 231 of the second transmission mechanism 230 serve as the main structure of the second transmission mechanism 230. These multiple conveying rollers 231 are arranged sequentially along the transmission direction of the second transmission mechanism 230, and are suitable for jointly conveying wood. The first transmission mechanism 220 and the third transmission mechanism 250 can be belt-type or chain-type transmissions, including a transmission belt / chain, pulleys / sprockets, and a first conveying motor / third conveying motor, with the conveying motor drivingly connected to the pulleys / sprockets. The first transmission mechanism 220 and the third transmission mechanism 250 can also use the same transmission method as the second transmission mechanism 230. The first transmission mechanism 220 and the third transmission mechanism 250 are suitable for long-distance transmission. Preferably, the first transmission mechanism 220 and the third transmission mechanism 250 are belt-type or chain-type transmissions, requiring fewer pulleys / sprockets than rollers, thus reducing equipment weight.

[0044] Reference Figure 1 , Figure 7 and Figure 8 It is understood that the spraying mechanism 240 includes one or more spray pipes, each equipped with multiple spray nozzles and / or spray heads; the spray pipes can be connected to tap water via on / off valves, allowing direct spraying of the peeled wood; the spraying mechanism 240 may also include a water pump, with the spray pipes connected to a water tank or reservoir via the water pump; the spraying mechanism 240 may also include a pressure boosting valve, with the spray pipes connected to tap water or a water pump via the pressure boosting valve.

[0045] The method of using this invention includes: placing wood into the groove 111, with the wood extending axially along the groove 111 during placement, or extending axially along the groove 111 under the action of the peeling roller 120 and the width limitation of the groove 111; as the peeling roller 120 rotates, the peeling claws 123 scrape / peel the outer wall of the wood, causing the bark to detach from the wood; the cross-section of the wood is circular, and the scraping of the wood by the peeling roller 120 is also suitable for driving the wood to roll, so that the bark in the circumferential direction of the wood is fully scraped off; the peeling roller 120 and the groove 111 are set to a certain length, and the wood moves while being peeled, so that the bark in the axial direction of the wood is fully scraped off; during the rolling of the wood, the bark is crushed. The bark and / or bark is scraped by the peeling claw 123, the bark is broken down and falls off through the slag discharge gap; the peeling roller 120 tumbles the wood, and some bark is pushed out during the wood movement; the peeled wood is transferred to the second transmission mechanism 230 via the first transmission mechanism 220; the wood is transported on multiple conveying rollers 231, and the spraying mechanism 240 sprays the wood, causing impurities such as dirt, sand, and bark residue on the surface of the wood to fall off the wood, and the impurities fall into the sewage collection and discharge tank 260 through the first impurity discharge port 233 or the second impurity discharge port 234; the sprayed wood is transferred to the third transmission mechanism 250 via the second transmission mechanism 230, and then transported outward via the third transmission mechanism 250.

[0046] Those skilled in the art will realize that the inclination of the slot 111 should not be too large to avoid the wood shifting too quickly.

[0047] Understandably, some wood has scratches on its surface after being peeled. The surface layer of this wood can be shaved or chipped into wood chips. These wood chips can be screened to separate the wood chips and shavings, and can be used as biomass fuel for boilers along with the bark.

[0048] Compared with the prior art, the beneficial effects of this application include: the differential rotation of the wood and the peeling roller 120 can combine the rolling characteristics of the wood, using the peeling roller 120 to scrape off the bark of the wood, resulting in multiple points of scraping in the circumferential direction of the wood, allowing the wood to be peeled more fully and quickly during rolling; the groove 111 is set at a certain inclination, allowing the wood to move synchronously during scraping, resulting in multiple points of scraping in the axial direction of the wood, allowing the wood to be peeled more fully and quickly during movement; the detached bark can be crushed by the rolling wood and / or scraped by the peeling claws 123, the bark is broken down, and falls through the slag discharge gap, the bark fragments... The discharge side improves the efficiency of the peeling device 100; the slot 111 can simultaneously accommodate multiple pieces of wood, which can rub against each other during tumbling to peel off residual small pieces of bark from the wood; the peeled wood can remove surface dirt and sand particles, avoiding damage to the shaving blades and preventing dirt and sand particles from being mixed into the shavings, effectively reducing the shavings impurity and improving the quality and strength of the particleboard; the wood can be peeled and waste removed, and the particleboard derived from this wood is of higher quality and strength, making it convenient to use small timber as the main raw material for particleboard, reducing the raw material cost of enterprises, making environmentally friendly use of small timber, avoiding the waste of small timber by burning, and improving the utilization rate of trees.

[0049] It is understood that in the method of use of the present invention, the feeding rate of the slot 111 is appropriately controlled to avoid the slot 111 being crowded with too much wood at the same time, and to prevent the wood from not being turned over.

[0050] In some embodiments of the invention, the cross-section of the slot 111 is U-shaped, and at least one sidewall of the working opening 111a corresponds to the lowest point of the U-shape, meaning that the wood at the lowest point of the U-shape is also scraped by the peeling roller 120. In a single batch of wood, the last piece of wood is continuously scraped in the slot 111, and even if the inclination of the slot 111 is small, the wood continues to vibrate and exits the slot 111 along the inclination.

[0051] Reference Figure 2 , Figure 3 and Figure 4 In some embodiments of the invention, the bottom of the slot 111 is provided with a flat surface. In a single batch of timber, the last piece of timber may remain in the slot 111, which is within the acceptable range for timber processing enterprises.

[0052] Reference Figure 2 , Figure 3 , Figure 6 In some embodiments of the present invention, the trough seat 110 is provided with a guide platform 117, through which the wood in the trough 111 is output. The guide platform 117 protrudes from the trough seat 110 along the discharge direction of the trough 111. In the present invention, the protruding guide platform 117 covers the end of the peeling roller 120, preventing bark and bark residue that may be output from the trough 111 from falling to the end of the peeling roller 120.

[0053] Reference Figure 5 In some embodiments of the present invention, the peeling roller 120 is provided with an even number of peeling claw groups at intervals along the circumference, and a single peeling claw group is provided with multiple peeling claws 123 at intervals along the axial direction of the peeling roller 120, with the peeling claws 123 of adjacent peeling claw groups being staggered. In the present invention, the wood is moved and peeled, and the wood obtains multiple scraping groups along the circumference. A single scraping group is provided with multiple scraping points at intervals along the axial direction, which facilitates the peeling of the bark from the wood in larger pieces, so that the wood is fully peeled.

[0054] Reference Figure 5 In some embodiments of the present invention, one or more sets of teeth are spaced apart along the axial direction on the peeling side of the peeling claw 123, and each set of teeth is provided with multiple peeling teeth 123a, so that the peeling claw 123 is single-finger or multi-finger. Due to the uncertainty of the local flatness of the wood, at least one set of teeth in a single peeling claw 123 can scrape the bark; in addition, multiple sets of teeth scraping the bark at the same time can improve the scraping force and range, so that the bark can be effectively peeled off.

[0055] In some embodiments of the present invention, peeling hooks are provided on the peeling side of the peeling claw 123.

[0056] Reference Figure 5 In some embodiments of the present invention, the peeling claw 123 is detachably connected to the peeling roller 120 by screws, and the peripheral wall of the peeling roller 120 is provided with a recess 122a suitable for limiting the peeling claw 123.

[0057] In some embodiments of the present invention, peeling claws 123 are arranged sequentially along a spiral line on the peeling roller 120. The spiral line extends spirally along the axial direction of the peeling roller 120, and all peeling claws 123 are divided into an even number of claw groups. The even number of claw groups are arranged at intervals along the circumference of the peeling roller 120, and a single claw group is provided with multiple peeling claws 123 at intervals along the axial direction of the peeling roller 120. In the present invention, the scraping force of the peeling claws 123 on the wood can be decomposed into tangential force and axial force. The tangential force is suitable for scraping the bark, and the axial force is suitable for driving the wood to move. Regarding "the spiral line extends spirally along the axial direction of the peeling roller 120," it can be understood that the spiral line is wound around the peeling roller 120. According to the right-hand rule, when the hand grasps the peeling roller 120, the direction of the middle finger is the tangential direction of the spiral line, and the direction of the thumb is the axial direction of the peeling roller 120.

[0058] Reference Figures 2 to 4 The peeling roller 120 rotates in the direction of W. (Refer to...) Figures 2 to 4 In some embodiments of the present invention, the peeling rollers 120 are classified into stacking peeling rollers 120a and counterweight peeling rollers 120b, which are higher than the stacking peeling rollers 120a, as shown below. Figure 4The circumferential high point of the counter-peeling roller 120b corresponds to one side wall of the groove 111. The stacking peeling roller 120a is closer to the other side wall of the groove 111 than the counter-peeling roller 120b. A timber stacking and tumbling zone 111b is suitable to be formed between the stacking peeling roller 120a and the counter-peeling roller 120b. This side wall of the groove 111 and the counter-peeling roller 120b are suitable for limiting the timber, causing the timber to float and tumble. (Refer to...) Figure 4 In this invention, when the stacking peeling roller 120a and the counterweight peeling roller 120b rotate, the tangential direction of their upper edges can be from one side wall of the groove 111 to the other side wall; the stacking peeling roller 120a and the counterweight peeling roller 120b jointly scrape the wood in the stacking tumbling zone 111b; see reference. Figure 4 Under the scraping action of the heavy peeling roller 120b and the stop provided by one side wall of the groove 111, the wood along the upper edge of the heavy peeling roller 120b can maintain balanced rolling for a short period, allowing the wood to continuously peel while floating (i.e., floating tumbling); see reference Figure 4 When the timber in the stacking and tumbling zone 111b climbs up the counterweight peeling roller 120b and pushes against the timber that was originally tumbling in balance, the timber that was originally tumbling in balance is thrown back into the stacking and tumbling zone 111b. The stacking and peeling roller 120a mainly peels the timber in the stacking and tumbling zone 111b, while the counterweight peeling roller 120b is also suitable for dynamically supporting the timber on its upper edge, exhibiting the characteristic of resisting gravity (i.e., counterweight).

[0059] Timber is typically cut to lengths of 1.7 meters or more. The groove 110 has a corresponding feed opening, and its length is generally three times or more the length of the timber to ensure thorough bark removal. Therefore, the peeling device 100 is a large piece of equipment, and the peeling roller 120 is a large roller shaft. To ensure strength, it is difficult to create a large opening at the end of the groove 110 to accommodate the peeling roller 120. To solve the installation problem of the peeling roller 120, refer to... Figure 5In some embodiments of the present invention, the peeling roller 120 includes a spindle 121 and a roller 122. Peeling claws 123 are disposed on the outer peripheral wall of the roller 122. The spindle 121 passes through the roller 122. One end of the spindle 121 is integrally formed with a flange 121a suitable for screw connection to one end of the roller 122. This end of the spindle 121 is connected to a slot seat 110 through an end cap 112. The slot seat 110 is provided with mounting holes suitable for the flange 121a to pass through and for the end cap 112 to be installed. It is understood that the spindle 121 is driven by a peeling motor. During the installation of the peeling roller 120, a crane is used to position the roller 122 into the groove seat 110, aligning the mounting holes of the roller 122 and the groove seat 110. The mandrel 121 is inserted into the roller 122 through the groove seat 110, and the flange 121a of the mandrel 121 is screwed to the roller 122. The mandrel 121 passes through the upper end cover 112, which is screwed to the groove seat 110. Preferably, the end cover 112 is connected to the mandrel 121 via a rolling bearing. Even better, the groove seat 110 is provided with the following opening and maintenance window 114.

[0060] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6 In some embodiments of the present invention, the trough seat 110 is provided with a slag discharge hopper 113, which is located below the trough chamber 111 and the peeling roller 120. The slag discharge hopper 113 is suitable for receiving the bark falling from the trough chamber 111. It is understood that the slag discharge hopper 113 has a larger upper opening and a smaller lower opening. The continuous rolling of the peeling roller 120 causes the bark / bark chips / wood chips falling from the trough chamber 111 to have non-directional characteristics. The upper opening of the slag discharge hopper 113 can better receive the bark, and then the material is discharged outward through the lower opening.

[0061] Reference Figure 2 , Figure 3 , Figure 4 and Figure 6 In some embodiments of the present invention, the trough seat 110 is integrally formed with the trough chamber 111 and the slag discharge hopper 113. A maintenance window 114 is provided between the lower end of the side wall of the trough chamber 111 and the slag discharge hopper 113. The maintenance window 114 is suitable for detaching and installing the peeling claws 123 on the peeling roller 120. The trough seat 110 is detachably connected with a protective plate 115, which is suitable for covering the maintenance window 114 and extends upward from the side wall of the slag discharge hopper 113. In the present invention, the side wall and end of the trough chamber 111, as well as the slag discharge hopper 113, are all integrally formed by the trough seat 110, such as by casting or welding, so that the trough seat 110 has greater strength. The protective plate 115 is suitable for preventing workers from touching the peeling roller 120 and for preventing the bark from splashing, guiding the bark back to the slag discharge hopper 113.

[0062] Reference Figure 3 , Figure 4 and Figure 6 In some embodiments of the present invention, the stacking and tumbling zone 111b is provided with a slide 118. The upper surface of the slide 118 is a plane, which is inclined along the axial direction of the groove 111. The slide 118 is suitable for supporting the timber in the stacking and tumbling zone 111b. The slide 118 is connected to the groove seat 110 by screws. The opening at the bottom of the groove 111 is divided into two working openings 111a by the slide 118. The opening at the bottom of the groove 111 is suitable for the roller 122 to be inserted into the groove seat 110.

[0063] Reference Figure 4 In some embodiments of the present invention, the higher end of the groove 111 is provided with a feed ramp 116 suitable for wood to roll in. The feed ramp 116 is provided with multiple bark-cutting blades 116a, which are spaced apart and arranged side by side along the extending direction of the feed ramp 116. The bark-cutting blades 116a are suitable for biting and cutting the bark of the wood that rolls off the feed ramp 116. In the present invention, the wood bark is first bitten and divided into multiple pieces along the circumference. These bark pieces can be peeled off more quickly after being scraped by the peeling claws 123.

[0064] In some embodiments of the present invention, the sidewall of the slot 111 is detachably connected to an extension wall, which extends upward from the sidewall of the slot 111.

[0065] Reference Figure 7 , Figure 9 The first transmission mechanism 220 includes a buffer belt 221 wound around a plurality of first pulleys 222. At least one first pulley 222 is connected to the frame 210 via a support 223 and a second elastic member 224. A bark drop opening is provided between the input end of the buffer belt 221 and the peeling device 100. The buffer belt 221 is adapted to receive timber sliding down the inclined groove 111. It is understood that the bark drop opening should not be too large to avoid the timber failing to be transmitted to the buffer belt 221. Preferably, the bark drop opening is less than 1 / 3 of the timber length.

[0066] Reference Figure 7 , Figure 8 In some embodiments of the present invention, the sewage collection and discharge trough 260 extends obliquely along its discharge direction, and the discharge direction of the segments of the sewage collection and discharge trough 260 located directly below the second transmission mechanism 230 is opposite to the transmission direction of the second transmission mechanism 230. In the present invention, more impurities are spilled at the input end of the second transmission mechanism 230, and less impurities are spilled at the output end of the second transmission mechanism 230. The sewage spilled at the output end of the second transmission mechanism 230 is simultaneously supplemented with water to flush the sewage collection and discharge trough 260, so that the sewage collection and discharge trough 260 can quickly flush away sewage and impurities.

[0067] In some embodiments of the present invention, a filter cake conveyor belt, a drainage trough, and a water collection tank are also included. The drainage trough is disposed below the filter cake conveyor belt, which is a mesh or wire mesh structure. The filter cake conveyor belt is connected to a corresponding transmission motor via a pulley drive. The input end of the filter cake conveyor belt is adapted to receive wastewater discharged from the wastewater discharge tank 260. The drainage trough is adapted to discharge water to the water collection tank, which is connected to the spraying mechanism 240 via a water pump. In this invention, water resources can be recycled and reused after filtering impurities, effectively improving water resource utilization efficiency.

[0068] Even better, the collection tank is divided into multiple sub-tanks by several filter plates, and the end sub-tank in the multiple sub-tanks is connected to the spray mechanism 240 by a water pump. The filter plates can be plastic sheets, felt sheets, carbon blocks, etc., and the operators can replace the filter plates regularly.

[0069] In some embodiments of the present invention, one or more drying mechanisms are provided along the transmission direction of the third transmission mechanism 250. The drying mechanisms are adapted to blow or bake the wood on the third transmission mechanism 250. After the cleaned wood moves away from the second transmission mechanism 230, its surface is dried promptly.

[0070] In some embodiments of the invention, the spraying mechanism 240 is adapted to spray hot water. The hot water can be supplied by a boiler, or an electric heating element can be installed in the water collection tank. Spraying hot water onto the wood facilitates faster air drying / baking of the wood surface later.

[0071] Reference Figure 8 In some embodiments of the present invention, the second transmission mechanism 230 further includes free rollers, and a plurality of conveying rollers 231 are arranged side by side with the free rollers at intervals.

[0072] Reference Figure 7 and Figure 8 In some embodiments of the present invention, the third transmission mechanism 250 includes a third transmission belt 251, a third pulley 252, and a third conveying motor. The third transmission belt 251 is wound around a plurality of third pulleys 252, such that the input end of the third transmission belt 251 is inclined downward. In the present invention, the washed wood is away from the second transmission mechanism 230 and the spraying mechanism 240. When the washed wood is placed into the input end of the third transmission mechanism 250, it rises upward via the third transmission belt 251, which facilitates the downward flow and removal of residual moisture through the input end of the transmission belt. It is understood that the third transmission belt 251 may be inclined as a whole or only at its input end.

[0073] Reference Figure 7 and Figure 8In some embodiments of the present invention, the input end of the third conveyor belt 251 is lower than the output end of the second conveyor mechanism 230. When the wood is fed into the third conveyor belt 251 from the second conveyor mechanism 230, it can be dehydrated by two pitching swings. Specifically, the beginning end of the wood protrudes from the output end of the second conveyor mechanism 230 and its downward swing hits the input end of the third conveyor belt 251, causing the moisture on the wood to detach from the wood due to inertia; the end of the wood completely detaches from the output end of the second conveyor mechanism 230 and its downward swing falls onto the input end of the third conveyor belt 251, causing the moisture on the wood to detach from the wood due to inertia.

[0074] Reference Figure 7 and Figure 8 In some embodiments of the present invention, at least one third pulley 252 is connected to the frame 210 via a bearing seat 253 and a first elastic element 254. When one end of the wood output by the second transmission mechanism 230 hits the transmission belt, the transmission belt can retract to a certain extent to buffer the impact of the wood. This buffering process also helps to remove water from the wood based on inertia. Similarly, when the other end of the wood hits the transmission belt, it is also buffered and dehydrated by inertia. The first elastic element 254 can be a spring, a disc spring, or an elastic plastic part, etc.

[0075] In some embodiments of the present invention, at least one conveying roller 231 has a rib on its peripheral wall. The rib extends spirally along the axial direction of the conveying roller 231 and is suitable for driving the wood to jump and roll. In the present invention, the wood jumps, rolls, and is sprayed in the second conveying mechanism 230, and the wood is thoroughly sprayed and washed. Regarding the phrase "the rib extends spirally along the axial direction of the conveying roller 231," it can be understood that the rib is wound around the conveying roller 231. According to the right-hand rule, when the hand grasps the conveying roller 231, the direction of the middle finger is tangential to the rib, and the direction of the thumb is axial to the conveying roller 231.

[0076] It also includes a bark collection belt 300, which is wound around multiple corresponding pulleys. The slag discharge hopper 113 and the output end of the filter conveyor belt are both located above the bark collection belt 300.

[0077] The above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Any modifications or equivalent substitutions that do not depart from the spirit and scope of the present invention should be covered within the scope of the technical solutions of the present invention.
