Description

Technical Field

[0001] This invention belongs to the technical field of dust removal equipment, specifically relating to an integrated intelligent air-washing device for purifying light, heavy, and metal pollutants from wood chips. Background Technology

[0002] The air-washed wood chip process uses high-speed airflow as the sorting medium, and utilizes the density difference between wood chips and impurities such as metal and dust to achieve efficient separation. This effectively removes impurities such as metal and dust from the wood chips, improves the cleanliness of the wood chips, and provides high-quality raw materials for subsequent processes.

[0003] In existing technologies, conventional wood chip air washing equipment can effectively separate lightweight wood chips and dust from wood chips. However, in actual production, the wood may contain metal foreign objects. Due to the large mass and density of these metal foreign objects, they exceed the air washing threshold and cannot be effectively removed by air washing. An additional process is required to handle them separately to prevent the metal foreign objects from entering subsequent processing stages with the wood chips, which could damage the equipment and cause safety accidents. At the same time, the separated and retained metal foreign objects will continue to accumulate inside the equipment, requiring operators to stop the machine for cleaning. This not only increases labor intensity but also interrupts the continuous production process and affects the overall processing efficiency. Summary of the Invention

[0004] Therefore, it is necessary to provide an integrated intelligent air-washing wood chip light, heavy and metal contaminant purification device to address the shortcomings of existing technologies and solve the problem that air-washing operations cannot separate metal contaminants from wood.

[0005] To solve the above problems, this application adopts the following technical solution: One objective of this application is to provide an integrated intelligent air-washing device for purifying light, heavy, and metal contaminants from wood chips, including an electrical control box and a housing. The housing is fixedly installed on the right side of the electrical control box. A rectangular frame is fixedly inserted through the side of the housing near the electrical control box. A side-blowing device is fixedly installed on the side of the electrical control box near the rectangular frame. The air outlet of the side-blowing device is flush with the inner wall of the rectangular frame. An inlet and a dust extraction port are provided at the top of the housing. Two symmetrically arranged collection hoppers are provided at the bottom of the housing. A motor bracket is fixedly installed on the surface of the housing. A dust extraction device is installed above the dust extraction port. The dust extraction port is sealed to the input end of the dust extraction device via a sealed pipe. The air outlet of the side-blowing device outputs a stable airflow with a set pressure in a horizontal direction. Simultaneously, the dust extraction device creates a negative pressure adsorption effect at the dust extraction port through the sealed pipe, causing the housing to... The internal structure forms a directional and stable airflow from the side-blowing device to the suction and dust removal port. It also includes: two rotating shafts, each rotatably penetrating the inner walls of both sides of the housing; a support plate, fixedly mounted on the circumferential surface of the rotating shafts, with an upward-facing hollow cavity inside; a plastic guide plate, fixedly mounted on the top of the support plate; several strong magnets, fixedly mounted on the side of the plastic guide plate near the support plate; and a servo motor, fixedly mounted on the surface of a motor bracket, with its output end connected to the rotating shaft near the motor bracket via a coupling. The servo motor drives the support plate to rotate at a uniform speed via the rotating shaft, and the output end of the servo motor drives the rotating shaft to rotate in a set direction. The rotating shaft, through the support plate, drives the plastic guide plate to rotate synchronously.

[0006] In some embodiments, several strong magnets are arranged symmetrically in two rows at the bottom of the plastic guide plate. The strong magnets are used to form a uniform and stable magnetic attraction area above the plastic guide plate. The magnetic attraction area set on the working surface of the plastic guide plate can reliably attract metal foreign objects, thereby achieving efficient separation of metal foreign objects from qualified wood chips.

[0007] In some embodiments, a rectangular groove is provided on the outer side wall of the plastic guide plate, and a scraper pusher is slidably installed on the rectangular groove. The scraper pusher contacts the metal foreign object adsorbed on the working surface of the plastic guide plate, so that the scraper pusher pushes the metal foreign object to move together.

[0008] In some embodiments, limit plates are fixedly installed on both ends of the scraper pusher plate. The limit plates are attached to the outer side wall of the plastic guide plate. The scraper pusher plate drives the limit plates to move synchronously. Both the scraper pusher plate and the limit plates are made of insulating plastic material.

[0009] In some embodiments, the bottom of the plastic guide plate is provided with a support device to improve its stability, and the support device is provided with an auxiliary device to improve the overall stability. The support device includes a rectangular plate, a mounting frame, and a round rod. The rectangular plate is fixedly installed on the inner wall of the box between two collection hoppers. The mounting frame is fixedly installed on the bottom of the plastic guide plate. The round rod is fixedly inserted through the surface of the mounting frame. The top of the rectangular plate has a groove adapted to the size of the round rod. The circumferential surface of the round rod fits against the inner wall of the groove. The rectangular plate provides stable support for the round rod through the groove. The support force is transmitted to the bottom of the plastic guide plate through the round rod and the mounting frame. The surface of the rectangular plate has a rectangular mounting groove.

[0010] In some embodiments, a wear-resistant rubber ring is fitted on the circumferential surface of the round rod. The circumferential surface of the wear-resistant rubber ring fits against the inner wall of the groove. The deformed wear-resistant rubber ring fits tightly against the inner wall of the groove, making the round rod and the groove fit more closely.

[0011] In some embodiments, the auxiliary device includes a base, a spring, a lifting plate, and a U-shaped support plate. The U-shaped support plate applies an upward thrust to the round rod during the upward movement, which works in conjunction with the driving force of the servo motor. The base is fixedly installed at the bottom of the inner wall of the rectangular mounting slot, the spring is fixedly installed at the top of the base, the lifting plate is fixedly installed at the top of the spring, and the U-shaped support plate is fixedly installed at the top of the lifting plate. The inner wall of the U-shaped support plate is in contact with the circumferential surface of the round rod.

[0012] In some embodiments, a circular tube is fixedly installed on the circumferential surface of the base, the circular tube is in contact with the bottom of the lifting plate, the spring in an elastically compressed state releases elastic potential energy, pushing the lifting plate to move up and disengage from the circular tube, and the U-shaped support plate is in contact with the side wall surface of the rectangular plate.

[0013] Compared with the prior art, the beneficial effects of the present invention are: This invention features a magnetic attraction area on the working surface of a plastic guide plate, which reliably adsorbs metallic foreign objects. By setting a uniform and stable magnetic attraction area on the working surface of the plastic guide plate, the separation of metallic foreign objects is achieved simultaneously during the conveying of qualified wood chips, preventing them from entering subsequent processing steps and causing safety hazards. At the same time, a scraper pusher moves the metallic foreign objects, causing them to fall into the left-side collection hopper. The plastic guide plate is driven to rotate by a servo motor, and the scraper pusher uses its own weight to slide and clean the material, automatically cleaning the metallic foreign objects adsorbed on the working surface of the plastic guide plate, and completing the efficient unloading and recycling of metallic foreign objects.

[0014] This invention uses a servo motor output to drive the carrier plate and plastic guide plate to rotate and reset. By driving the plastic guide plate to rotate back and forth, the removal of metal foreign objects and the automatic reset of the scraper push plate can be completed in sequence. This ensures that the magnetic attraction area maintains a high-efficiency adsorption state and makes full use of the intermittent standby time, thereby improving the smoothness of continuous operation.

[0015] This invention provides stable support for a round rod through a groove in a rectangular plate. The rectangular plate forms a solid support and limit for the round rod, which not only effectively improves the stability of the plastic guide plate under the impact of wood, but also prevents the plastic guide plate from excessively rotating and colliding. At the same time, the deformed wear-resistant rubber ring fits tightly against the inner wall of the groove, making the round rod and the groove fit more closely. The wear-resistant rubber ring compensates for gap errors, further improving the tightness of the fit between the round rod and the groove, and ensuring the reliability of the rectangular plate support.

[0016] This invention applies an upward thrust to the round rod during the upward movement of the U-shaped support plate. By providing auxiliary thrust to the round rod through the U-shaped support plate, the smoothness of operation in the initial stage of plastic guide plate angle adjustment is effectively improved, making the angle adjustment of plastic guide plate easier and smoother. At the same time, the U-shaped support plate supports the round rod and moves it down smoothly until the round rod is precisely fitted with the groove. By supporting the round rod and moving it down smoothly through the U-shaped support plate, the precise fit between the round rod and the groove is ensured, thereby improving the overall stability of the air-washing wood chip operation.

[0019] The specific embodiments of the present invention will now be described in detail with reference to the accompanying drawings, but it should be understood that the scope of protection of the present invention is not limited to the specific embodiments.

[0020] like Figure 1 - Figure 5 As shown, one embodiment of the present invention is: an integrated intelligent air-washing wood chip light, heavy, and metal pollutant purification device, including an electrical control box 1 and a housing 2. The housing 2 is fixedly installed on the right side of the electrical control box 1. A rectangular frame is fixedly inserted through the side of the housing 2 near the electrical control box 1. A side blowing device 3 is fixedly installed on the side of the electrical control box 1 near the rectangular frame. The air outlet of the side blowing device 3 is fitted to the inner wall of the rectangular frame. A feed inlet 4 and a dust extraction port 5 are provided at the top of the housing 2. Two symmetrically arranged collection hoppers 6 are provided at the bottom of the housing 2. A motor bracket is fixedly installed on the surface of the housing 2. A dust extraction device is provided above the dust extraction port 5. The dust extraction port 5 is sealed to the input end of the dust extraction device through a sealed pipe. The device also includes: two rotating shafts 7, which rotate through the housing 2 respectively. On the inner walls of both sides of the housing 2; a support plate 8, which is fixedly installed on the circumferential surface of the rotating shaft 7, and has an upward-facing hollow cavity inside the support plate 8; a plastic guide plate 9, which is fixedly installed on the top of the support plate 8; several strong magnets 10, which are fixedly installed on the side of the plastic guide plate 9 near the support plate 8; and a servo motor 11, which is fixedly installed on the surface of the motor bracket, and whose output end is fixedly connected to the rotating shaft 7 near the motor bracket via a coupling. The servo motor 11 drives the support plate 8 to rotate at a uniform speed through the rotating shaft 7, and drives the plastic guide plate 9 to reciprocate, making full use of the intermittent standby time and improving the smoothness of continuous operation.

[0021] Several strong magnets 10 are arranged symmetrically in two rows at the bottom of the plastic guide plate 9. The strong magnets 10 are used to form a uniform and stable magnetic attraction area above the plastic guide plate 9. By setting a uniform and stable magnetic attraction area on the working surface of the plastic guide plate 9, the separation of metal foreign objects can be completed simultaneously during the conveying of qualified wood chips.

[0022] A rectangular groove is provided on the outer side wall of the plastic guide plate 9. A scraper pusher plate 12 is slidably installed on the rectangular groove. By utilizing the weight of the scraper pusher plate 12, the material is slidably cleaned, and the metal foreign objects adsorbed on the working surface of the plastic guide plate 9 can be automatically cleaned.

[0023] Limiting plates 13 are fixedly installed on both ends of the scraper pusher plate 12. The limiting plates 13 are attached to the outer side wall of the plastic guide plate 9. Both the scraper pusher plate 12 and the limiting plates 13 are made of insulating plastic. By setting the limiting plates 13 at both ends of the scraper pusher plate 12, the scraper pusher plate 12 is prevented from shifting, which could cause problems with material cleaning.

[0024] In this embodiment, before the wood is placed in the container, the staff starts the side blowing device 3 and the dust collection equipment through the electrical control box 1. The air outlet of the side blowing device 3 outputs a stable airflow with a set air pressure in the horizontal direction. At the same time, the dust collection equipment forms a negative pressure adsorption effect at the suction and dust removal port 5 through the sealed pipe, so that a directional and stable airflow from the side blowing device 3 to the suction and dust removal port 5 is formed inside the box 2. When feeding wood, the wood enters the box 2 from directly above the inlet 4 and passes through the outlet area of ​​the side blowing device 3 during its fall. The directional airflow between the outlet and the suction dust removal port 5 washes the mixed wood. Light wood chips and dust in the wood are carried by the airflow and discharged from the box 2 through the suction dust removal port 5 under the negative pressure adsorption for unified collection and treatment. Wood chips and metal foreign objects with a mass greater than the set threshold pass smoothly through the airflow area and fall onto the plastic guide plate 9. The plastic guide plate 9 guides and conveys wood chips and metal foreign objects, moving them towards the right-side collection hopper 6. During the conveying process, the magnetic attraction area set on the working surface of the plastic guide plate 9 reliably adsorbs metal foreign objects, achieving efficient separation of metal foreign objects from qualified wood chips. After being removed from the plastic guide plate 9, the purified wood chips fall into the right-side collection hopper 6 and enter the subsequent processing steps. By setting a uniform and stable magnetic attraction area on the working surface of the plastic guide plate 9, the separation of metal foreign objects is completed simultaneously during the conveying of qualified wood chips, preventing metal foreign objects from entering the subsequent processing steps and causing safety hazards. After a single wood chip air washing process is completed, the operator starts the servo motor 11 through the electrical control box 1. The output of the servo motor 11 drives the rotating shaft 7 to rotate in a set direction. The rotating shaft 7 drives the plastic guide plate 9 to rotate synchronously through the bearing plate 8. The plastic guide plate 9 then drives the strong magnet 10 and the scraper push plate 12 to rotate together. During the rotation of the plastic guide plate 9, the height of its left side gradually decreases compared to its right side, causing the scraper push plate 12 to slide along the rectangular groove to the left side of the plastic guide plate 9 under its own weight and the guiding action of the plastic guide plate 9, and driving the limiting plate 13 to move synchronously. During the sliding process, the scraper push plate 12... The material pusher plate 12 comes into contact with the metal foreign object adsorbed on the working surface of the plastic guide plate 9, causing the scraper pusher plate 12 to push the metal foreign object to move together until the scraper pusher plate 12 slides to the right end of the rectangular chute. At this time, the metal foreign object is released from the magnetic attraction area and falls into the left collection hopper 6 under the guidance of the plastic guide plate 9, completing the rapid recovery of the metal foreign object. The plastic guide plate 9 is driven to rotate by the servo motor 11, and the scraper pusher plate 12 is used to slide and clean the material, which can automatically clean the metal foreign object adsorbed on the working surface of the plastic guide plate 9, and complete the efficient unloading and recovery of the metal foreign object. After the scraper pusher 12 completes the removal of metal foreign objects, the output end of the servo motor 11 drives the carrier plate 8 and the plastic guide plate 9 to rotate and reset. During this process, the left side of the plastic guide plate 9 gradually becomes higher than the right side, causing the scraper pusher 12 to slide and reset along the rectangular slide groove to the right side of the plastic guide plate 9 under its own weight and the guiding action of the plastic guide plate 9. By driving the plastic guide plate 9 to rotate back and forth through the servo motor 11, the removal of metal foreign objects and the automatic reset of the scraper pusher 12 can be completed in sequence. This ensures that the magnetic adsorption area maintains a highly efficient adsorption state and makes full use of the intermittent standby time, improving the smoothness of continuous operation.

[0025] Please see Figure 1 - Figure 8 In another embodiment of the present invention, based on the above embodiments, the bottom of the plastic guide plate 9 is provided with a support device for improving its stability, and the support device is provided with an auxiliary device for improving overall stability. The support device includes a rectangular plate 21, a mounting frame 22 and a round rod 23. The rectangular plate 21 is fixedly installed on the inner wall of the box 2 between the two collection hoppers 6. The mounting frame 22 is fixedly installed on the bottom of the plastic guide plate 9. The round rod 23 is fixedly inserted through the surface of the mounting frame 22. The top of the rectangular plate 21 is provided with a groove that matches the size of the round rod 23. The circumferential surface of the round rod 23 fits against the inner wall of the groove. The surface of the rectangular plate 21 is provided with a rectangular mounting groove. The rectangular plate 21 provides a stable support for the round rod 23, effectively improving the stability of the plastic guide plate 9 under the impact of wood.

[0026] A wear-resistant rubber ring 24 is fitted on the circumferential surface of the round rod 23. The circumferential surface of the wear-resistant rubber ring 24 fits against the inner wall of the groove. The wear-resistant rubber ring 24 compensates for the gap error, further improving the tightness of the fit between the round rod 23 and the groove, and ensuring the reliability of the support of the plastic rectangular plate 21.

[0027] The auxiliary device includes a base 31, a spring 32, a lifting plate 33, and a U-shaped support plate 34. The base 31 is fixedly installed at the bottom of the inner wall of the rectangular mounting groove, the spring 32 is fixedly installed at the top of the base 31, the lifting plate 33 is fixedly installed at the top of the spring 32, and the U-shaped support plate 34 is fixedly installed at the top of the lifting plate 33. The inner wall of the U-shaped support plate 34 is in contact with the circumferential surface of the round rod 23. The U-shaped support plate 34 provides auxiliary thrust to the round rod 23, effectively improving the smoothness of operation of the plastic guide plate 9 in the initial stage of angle adjustment.

[0028] A round tube 35 is fixedly installed on the circumferential surface of the base 31. The round tube 35 contacts the bottom of the lifting plate 33. The U-shaped support plate 34 is attached to the side wall surface of the rectangular plate 21. The round rod 23 is supported by the U-shaped support plate 34 and moved down smoothly, ensuring that the round rod 23 is precisely attached to the groove.

[0029] In this embodiment, when the plastic guide plate 9 is at its initial angle, the round rod 23 and the groove of the rectangular plate 21 remain in contact. The rectangular plate 21 provides stable support for the round rod 23 through the groove. This support force is transmitted to the bottom of the plastic guide plate 9 through the round rod 23 and the mounting frame 22, effectively improving the stability of the plastic guide plate 9 at its initial angle and ensuring that the plastic guide plate 9 maintains a stable posture during the air washing operation. At the same time, the rectangular plate 21 limits the rotation of the round rod 23 through the groove, which can limit the rotation range of the plastic guide plate 9 and prevent it from tilting excessively and colliding with the inner wall of the box 2. The rectangular plate 21 provides stable support and limits the round rod 23, which not only effectively improves the stability of the plastic guide plate 9 under the impact of wood, but also prevents the plastic guide plate 9 from rotating excessively and colliding. When the plastic guide plate 9 rotates, it drives the mounting frame 22 to move away from the rectangular plate 21. The mounting frame 22 simultaneously drives the round rod 23 and the wear-resistant rubber ring 24 to move. During this process, the round rod 23 disengages from the groove, and the wear-resistant rubber ring 24, which is in an elastic compression state, disengages from the groove and elastically recovers after disengaging from the groove. During the rotation and reset process of the plastic guide plate 9, it drives the mounting frame 22, the round rod 23 and the wear-resistant rubber ring 24 to move towards the rectangular plate 21. During this process, the wear-resistant rubber ring 24 first contacts the inner wall of the groove. As the round rod 23 gradually embeds into the groove, the wear-resistant rubber ring 24 undergoes elastic deformation under the joint compression of the round rod 23 and the inner wall of the groove. After deformation, the wear-resistant rubber ring 24 fits tightly against the inner wall of the groove, making the round rod 23 fit more tightly with the groove. By compensating for the gap error through the wear-resistant rubber ring 24, the tightness of the fit between the round rod 23 and the groove is further improved, ensuring the reliability of the support of the plastic rectangular plate 21. As the round rod 23 moves upward along the groove, its pressure on the U-shaped support plate 34 gradually decreases. The spring 32, which is in an elastic compression state, releases its elastic potential energy, pushing the lifting plate 33 upward and disengaging from the round tube 35. At the same time, the lifting plate 33 drives the U-shaped support plate 34 to move upward synchronously. During the upward movement, the U-shaped support plate 34 applies an upward thrust to the round rod 23, which works in conjunction with the driving force of the servo motor 11 to make the angle adjustment of the plastic guide plate 9 easier and smoother. After the round rod 23 separates from the U-shaped support plate 34, the auxiliary thrust disappears. The U-shaped support plate 34 provides auxiliary thrust to the round rod 23, effectively improving the operational stability of the plastic guide plate 9 in the initial stage of angle adjustment, making the angle adjustment of the plastic guide plate 9 easier and smoother. When the round rod 23 moves back to the groove side, it first fits against the inner wall of the U-shaped support plate 34, and then applies pressure to the U-shaped support plate 34, causing the U-shaped support plate 34 to drive the lifting plate 33 to move down synchronously. During the downward movement of the lifting plate 33, it fits against the round tube 35 and compresses the spring 32. The spring 32 is compressed and generates elastic deformation, forming an upward elastic reaction force. This elastic reaction force allows the U-shaped support plate 34 to support the round rod 23 and move down smoothly until the round rod 23 is precisely fitted against the groove. By supporting the round rod 23 and moving it down smoothly through the U-shaped support plate 34, the precise fit between the round rod 23 and the groove is ensured, thereby improving the overall stability of the air-washed wood chip operation.
