Description

Technical Field

[0001] This utility model belongs to the technical field of impurity removal mechanisms, specifically a high-efficiency impurity removal device. Background Technology

[0002] "Fan-based impurity removal" is a physical separation technology that uses the airflow generated by a fan to separate light impurities (such as dust, lint, shredded paper, shriveled grains, straw fragments, etc.) mixed in materials. It is widely used in grain processing, agricultural product cleaning, medicinal material screening, and industrial raw material purification.

[0003] "Fan-driven impurity removal" typically consists of a fan, a feeding device, a separation channel, and a collection device. Its core principle is to separate materials and impurities by utilizing the density and weight differences between them under the action of airflow. However, during long-term use and observation, it was found that the material to be separated accumulated and blocked the separation channel, leading to reduced airflow velocity and uneven airflow distribution. Impurities that should have been carried away remained due to insufficient airflow, reducing the separation purity.

[0004] Therefore, this utility model provides a high-efficiency impurity removal device. Utility Model Content

[0005] To overcome the shortcomings of the prior art and solve at least one of the problems mentioned in the background art, a highly efficient impurity removal device is proposed.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The high-efficiency impurity removal device of this utility model includes a base; a feeding box is fixed on the top of the base; a buffer assembly is provided in the middle of the inner side wall of the feeding box; an inlet pipe is installed in the middle of the inner side wall of the feeding box; a connecting box is connected to the bottom of the inlet pipe; the buffer assembly is fixed below the connecting box; an impurity removal box is connected to the top of the base; the impurity removal box and the connecting box are connected; multiple discharge boxes are connected in the middle of the side wall of the impurity removal box; a shaking assembly is provided in the middle of the inner side wall of the impurity removal box; the shaking assembly and the discharge box are correspondingly arranged; a collection assembly is provided on the top of the impurity removal box; a first motor is assembled in the middle of the inner side wall of the base; a first movable shaft is fixed to the output end of the first motor; multiple fan blades are fixed in the middle of the side wall of the first movable shaft; the fan blades are located below the impurity removal box; a ventilation opening is opened in the middle of the side wall of the base; the shaking assembly includes multiple grooves; multiple grooves are symmetrically opened on the inner wall of the impurity removal box; the grooves and the discharge boxes are correspondingly arranged; the grooves are... The structure is inclined; multiple helical springs are fixed in the middle of the inner wall of the groove; a material drop plate is installed at the other end of the helical spring; the material drop plate slides inside the groove; multiple dustproof cloths are fixed between the material drop plate and the impurity removal box; the dustproof cloths are made of elastic material; the dustproof cloths cover the outside of the groove; this step, by setting up the groove, helical springs and material drop plate, can shake off the particles attached to the filter holes of the material drop plate through vibration, reduce pore blockage, and keep the airflow generated by the fan blades stable in flow rate and speed, thereby maintaining the consistency of impurity removal effect. At the same time, the multi-stage material drop plate can keep the material or airflow relatively stable in flow rate by gradually reducing the aperture. The large aperture material drop plate allows most materials and small impurities to pass through, the medium aperture material drop plate further screens, and the small aperture material drop plate finely filters, reducing the sudden change in flow rate caused by local blockage, making the impurity removal process continuous and stable. By setting up the dustproof cloth, impurities can be intercepted and prevented from entering the groove, reducing the impurities from hindering the movement of the material drop plate, allowing the material drop plate to shake freely and continuously perform the separation function.

[0007] Preferably, a second motor is installed in the middle of the side wall of the feed box; a second movable shaft is fixedly connected to the output end of the second motor; a material distribution plate is fixed in the middle of the side wall of the second movable shaft; the material distribution plate is located inside the feed pipe; this step, by setting the second motor, the second movable shaft and the material distribution plate, can control the amount of material entering each batch, so that the material is evenly distributed on the top of the material drop plate and fully contacts the airflow. If a large amount of material rushes in at once, it will cause the local airflow to be "squeezed", the flow rate to be disordered, and even form a "material accumulation zone". Feeding in batches helps to effectively expose impurities in the airflow and improve separation efficiency.

[0008] Preferably, the collection component includes a collection box; the collection box is inserted into the top of the impurity removal box; a pair of guide plates are fixed in the middle of the inner side wall of the collection box; the guide plates are arranged in an arc shape; this step, by setting up the collection box and guide plates, can concentrate and collect impurities, prevent them from spreading or mixing back, and reduce the secondary pollution of the separated materials. At the same time, the arc-shaped guide plates can play a "buffering" role, allowing impurities to fall smoothly into the collection component, reducing the direct impact on the collection box, and reducing equipment wear and maintenance frequency.

[0009] Preferably, an electric push rod is installed in the middle of the side wall of the feed box; a push plate is fixedly connected to the output end of the electric push rod; an inclined plate is fixed in the middle of the side wall of the push plate; the inclined plate slides inside the connecting box; the inclined plate is set with an inclined structure; this step, by setting the electric push rod, push plate and inclined plate, can actively push the accumulated material to the discharge plate, so that there is always material passing through the discharge plate, reducing system downtime or efficiency reduction caused by accumulation, and ensuring the continuous and effective operation of the impurity removal equipment.

[0010] Preferably, the buffer assembly includes multiple damping springs; the damping springs are fixed to the inner wall of the feed box; a buffer plate is fixed to the other end of the damping spring; the connecting box is installed on top of the buffer plate; this step of setting up the damping springs and buffer plate can absorb the impact force through their own deformation, reduce the collision force between the connecting box and the feed box, reduce the loosening of the connecting box due to continuous impact, and extend the service life of the connecting box.

[0011] Preferably, the top of the collection box is fixed with multiple handles; the handles are located above the removal box; this step, by setting the handles, can provide a stable point of force application, allowing workers to easily lift or move the collection box through the handles, assisting in installation and disassembly, and improving the ease of operation.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. The high-efficiency impurity removal device of this utility model, by setting grooves, spiral springs and discharge plates, can shake off particles attached to the filter holes of the discharge plate through vibration, reduce pore blockage, and maintain a stable flow rate and speed of airflow generated by the fan blades, thereby maintaining the consistency of impurity removal effect. At the same time, the multi-stage discharge plates, by gradually reducing the aperture, can keep the material or airflow at a relatively stable flow rate. The large aperture discharge plate allows most materials and small impurities to pass through, the medium aperture discharge plate further screens, and the small aperture discharge plate performs fine filtration, reducing sudden changes in flow rate caused by local blockage, making the impurity removal process continuous and stable. By setting a dustproof cloth, impurities can be intercepted and prevented from entering the groove, reducing the obstruction of the discharge plate's movement by impurities, allowing the discharge plate to shake freely and continuously perform its separation function.

[0014] 2. The high-efficiency impurity removal device of this utility model can control the amount of material entering each batch by setting a second motor, a second movable shaft and a distribution plate, so that the material is evenly distributed on the top of the material drop plate and fully contacts the airflow. If a large amount of material is poured in at once, it will cause the local airflow to be "squeezed", the flow rate to be disordered, and even form a "material accumulation zone". Feeding in batches helps to effectively expose impurities in the airflow and improve separation efficiency. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Specific implementation examples are given below.

[0025] like Figures 1 to 5As shown, the high-efficiency impurity removal device of this utility model embodiment includes a base 1; a feeding box 11 is fixed to the top of the base 1; a buffer assembly is provided in the middle of the inner side wall of the feeding box 11; an inlet pipe 12 is installed in the middle of the inner side wall of the feeding box 11; a connecting box 13 is connected to the bottom of the inlet pipe 12; the buffer assembly is fixed below the connecting box 13; an impurity removal box 14 is connected to the top of the base 1; the impurity removal box 14 and the connecting box 13 are connected; multiple discharge boxes 15 are connected in the middle of the side wall of the impurity removal box 14; a shaking assembly is provided in the middle of the inner side wall of the impurity removal box 14; the shaking assembly and the discharge box 15 are correspondingly arranged; a collection assembly is provided at the top of the impurity removal box 14; a first motor 16 is assembled in the middle of the inner side wall of the base 1; a first movable shaft 17 is fixed to the output end of the first motor 16; multiple fan blades 18 are fixed in the middle of the side wall of the first movable shaft 17; the fan blades 18 are located below the impurity removal box 14; the side wall of the base 1 A ventilation opening 19 is provided in the middle. When the operator starts the first motor 16, the first motor 16 will drive the first movable shaft 17 to rotate. When the first movable shaft 17 rotates, it will drive multiple fan blades 18 to rotate. When the fan blades 18 rotate, they will fan the airflow inside the base 1 and the impurity removal box 14. Then the operator pours the industrial material to be impurized into the feed box 11 through the feed pipe 12. At this time, the material will fall into the connecting box 13. At the same time, the buffer component will buffer the impact of the material on the connecting box 13 from the bottom of the connecting box 13. Because the connecting box 13, the impurity removal box 14 and the discharge box 15 are connected, the material will pass through the connecting box 13 and enter the impurity removal box 14. Then the material will fall onto the top of the shaking component. The shaking component will separate the material from the impurities during the vibration. At the same time, the airflow fanned by the fan blades 18 will blow the impurities toward the collection component and be collected by the collection component.

[0026] like Figure 2 and Figure 4As shown, the material shaking assembly includes multiple grooves 2; multiple grooves 2 are symmetrically arranged on the inner wall of the impurity removal box 14; the grooves 2 and the discharge box 15 are correspondingly arranged; the grooves 2 are arranged with an inclined structure; multiple helical springs 21 are fixed in the middle of the inner side wall of the groove 2; a drop plate 22 is installed at the other end of the helical spring 21; the drop plate 22 slides inside the groove 2; multiple dustproof cloths 23 are fixed between the drop plate 22 and the impurity removal box 14; the dustproof cloths 23 are made of elastic material; the dustproof cloths 23 cover the outside of the groove 2; when industrial material passes through the connecting box 13 and falls onto the top of the drop plate 22 inside the impurity removal box 14, the falling material will vibrate the drop plate 22, causing the drop plate 22 to shake continuously inside the groove 2 under the drive of the multiple helical springs 21. During the shaking process, impurities in the material will be separated from it. At the same time, multiple drop plates 22 and discharge boxes with different diameters are arranged. 15. Multi-stage impurity removal can be performed according to the material size. This step, through the setting of groove 2, spiral spring 21 and drop plate 22, can shake off the particles attached to the filter holes of drop plate 22 by vibration, reduce pore blockage, and keep the airflow generated by fan blade 18 at a stable flow rate and speed, thereby maintaining the consistency of impurity removal effect. At the same time, the multi-stage drop plate 22 can keep the material or airflow at a relatively stable flow rate by gradually reducing the aperture. The large aperture drop plate 22 allows most materials and small impurities to pass through, the medium aperture drop plate 22 further screens, and the small aperture drop plate 22 performs fine filtration, reducing the sudden change in flow rate caused by local blockage, making the impurity removal process continuous and stable. By setting dustproof cloth 23, impurities can be intercepted and prevented from entering the interior of groove 2, reducing the impurities that hinder the movement of drop plate 22, allowing drop plate 22 to shake freely and continuously perform the separation function.

[0027] like Figure 2 , Figure 3 and Figure 5 As shown, a second motor 3 is installed in the middle of the side wall of the feed box 11; a second movable shaft 31 is fixedly connected to the output end of the second motor 3; a distribution plate 32 is fixed in the middle of the side wall of the second movable shaft 31; the distribution plate 32 is located inside the feed pipe 12; when the operator starts the second motor 3, the second motor 3 will drive the second movable shaft 31 to rotate, and when the second movable shaft 31 rotates, it will drive the distribution plate 32 to rotate inside the feed pipe 12. When the material passes through the feed pipe 12 and enters the connecting box 13, the material will first accumulate on the surface of the distribution plate 32 and fall off as the distribution plate 32 rotates. This step, by setting the second motor 3, the second movable shaft 31 and the distribution plate 32, can control the amount of material entering each batch, so that the material is evenly distributed on the top of the drop plate 22 and fully contacts the airflow. If a large amount of material rushes in at once, it will cause the local airflow to be "squeezed", the flow rate to be disordered, and even form a "material accumulation zone". Feeding in batches helps to effectively expose impurities in the airflow and improve separation efficiency.

[0028] like Figures 1 to 4As shown, the collection component includes a collection box 4; the collection box 4 is inserted into the top of the impurity removal box 14; a pair of guide plates 41 are fixed in the middle of the inner side wall of the collection box 4; the guide plates 41 are set with an arc-shaped structure; when the operator installs the collection box 4 on the top of the impurity removal box 14, when the airflow carries impurities outward from the top of the impurity removal box 14, the impurities will flow along the surface of the pair of arc-shaped guide plates 41 and fall onto the top of the guide plates 41 under the influence of the airflow. At this time, the impurities are no longer affected by the airflow and will naturally fall onto the top of the guide plates 41 and be collected by the guide plates 41. This step, by setting the collection box 4 and the guide plates 41, can concentrate and collect the impurities, prevent them from spreading or mixing back, and reduce the secondary pollution of the separated materials. At the same time, the arc-shaped guide plates 41 can play a "buffering" role, allowing the impurities to fall smoothly into the collection component, reducing the direct impact on the collection box 4, and reducing equipment wear and maintenance frequency.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, an electric push rod 5 is installed in the middle of the side wall of the feed box 11; a push plate 51 is fixedly connected to the output end of the electric push rod 5; an inclined plate 52 is fixed in the middle of the side wall of the push plate 51; the inclined plate 52 slides inside the connecting box 13; the inclined plate 52 is set with an inclined structure; when the material accumulates inside the connecting box 13, the operator starts the electric push rod 5, which pushes the push plate 51 to move. At this time, the push plate 51 will drive the inclined plate 52 to move synchronously. During the movement, the inclined plate 52 will push the material accumulated inside the connecting box 13 to the top of the discharge plate 22. This step, by setting the electric push rod 5, the push plate 51 and the inclined plate 52, can actively push the accumulated material to the discharge plate 22, so that there is always material passing through the discharge plate 22, reducing system downtime or efficiency reduction caused by accumulation, and ensuring the continuous and effective operation of the impurity removal equipment.

[0030] like Figure 2 and Figure 5 As shown, the buffer assembly includes multiple damping springs 6; the damping springs 6 are fixed to the inner wall of the feed box 11; the other end of the damping spring 6 is fixed to a buffer plate 61; the connecting box 13 is installed on top of the buffer plate 61; this step of setting up the damping springs 6 and the buffer plate 61 can absorb the impact force through their own deformation, reduce the collision force between the connecting box 13 and the feed box 11, reduce the loosening of the connecting box 13 due to continuous impact, and extend the service life of the connecting box 13.

[0031] like Figures 1 to 4 As shown, multiple handles 7 are fixed on the top of the collection box 4; the handles 7 are located above the removal box 14; this step provides a stable force application point by setting the handles 7, allowing the staff to easily lift or move the collection box 4 through the handles 7, assisting in installation and disassembly, and improving the ease of operation.

[0032] Working principle: The operator starts the first motor 16, which drives the first movable shaft 17 to rotate. When the first movable shaft 17 rotates, it drives multiple fan blades 18 to rotate. When the fan blades 18 rotate, they agitate the airflow inside the base 1 and the impurity removal box 14. Then, the operator pours the industrial material to be impurized into the feed box 11 through the feed pipe 12. At this time, the material will fall into the connecting box 13. Simultaneously, the buffer component will buffer the impact of the material on the connecting box 13 from the bottom. Because the connecting box 13, the impurity removal box 14, and the discharge box 15 are connected... The material passes through the connecting box 13 and enters the impurity removal box 14. It then falls onto the top of the shaking assembly, which separates the material from impurities during vibration. Simultaneously, the airflow from the fan blades 18 blows the impurities towards the collection assembly, where they are collected. When the industrial material falls through the connecting box 13 onto the top of the discharge plate 22 inside the impurity removal box 14, the falling material vibrates the discharge plate 22, causing it to continuously shake within the groove 2 under the action of multiple helical springs 21. During this shaking process, impurities within the material are removed. It will separate from the material, and at the same time, multiple material drop plates 22 with different diameters and discharge boxes 15 are set up to perform multi-stage impurity removal according to the size of the material. The operator starts the second motor 3, which drives the second movable shaft 31 to rotate. When the second movable shaft 31 rotates, it drives the material distribution plate 32 to rotate inside the feed pipe 12. When the material passes through the feed pipe 12 and enters the connecting box 13, the material will first accumulate on the surface of the material distribution plate 32 and fall off as the material distribution plate 32 rotates. The operator installs the impurity collection box 4 on the top of the impurity removal box 14. When the airflow carries impurities from the material removal box 14, the material will be removed from the material removal box 14. When the top of the impurity box 14 flows outward, the impurities will flow along the surface of a pair of arc-shaped guide plates 41 and fall to the top of the guide plates 41 under the influence of the airflow. At this time, the impurities are no longer affected by the airflow and will naturally fall to the top of the guide plates 41 and be collected by the guide plates 41. When the material accumulates inside the connecting box 13, the operator starts the electric push rod 5, which pushes the push plate 51 to move. At this time, the push plate 51 will drive the inclined plate 52 to move synchronously. During the movement, the inclined plate 52 will push the material accumulated inside the connecting box 13 to the top of the drop plate 22.
