Description

Technical Field

[0001] This invention is a recyclable material re-sorting device that improves the efficiency of foreign object removal after sorting aluminum cans, steel cans, etc. by the collision of the recyclable material with the collision wall. After the collision with the collision wall, the recyclable material falls down along the stop of the recyclable material, and at the same time, the foreign object attached to the recyclable material is scraped off by the elastic baffle. Background Technology

[0002] Among recyclable materials, the method of using aluminum scrap cans to manufacture aluminum gold is to recycle aluminum scrap cans. After manually separating the steel cans and impurities from the collected scrap cans, the aluminum scrap cans are placed in a crucible furnace to melt, and the molten pool is poured into a mold to manufacture recycled aluminum gold.

[0003] According to the current aluminum recycling method, when dissolving aluminum waste containers, the yield can reach approximately 60% based on foreign matter adhering to the containers. This yield is inefficient in terms of production efficiency and economics, and poses safety hazards.

[0004] To address these issues, there is an urgent need to develop devices that can improve the efficiency of foreign matter removal from recyclables, especially aluminum waste containers, and increase the recovery rate.

[0008] The problem that the invention aims to solve

[0009] The present invention aims to solve the aforementioned problems.

[0010] The purpose is to screen aluminum cans, steel cans, etc. through the screening section, and then remove foreign objects attached to the recyclables in one go by colliding with the collision wall. After colliding with the collision wall, the recyclables fall down along the foreign object removal section, and at the same time, the foreign objects attached to the recyclables are scraped off by the elastic baffle, thereby improving the efficiency of foreign object removal and providing a recyclable recycling device that improves the recyclable removal rate.

[0011] means for solving problems

[0012] The recyclable material screening device for improving yield according to the present invention includes a screening section for screening recyclable materials based on their material composition; a collision wall for initially removing foreign matter contained in recyclable perfume by colliding with the recyclable materials screened from the screening section; and a foreign matter agent placed at the lower part of the collision wall to guide the falling recyclable materials to slide down after the collision and to prevent the removal of foreign matter scraped off from the sliding recyclable materials.

[0013] According to the present invention, the foreign object removal device is characterized in that a guide rail portion is disposed at the lower part of the collision wall to guide the sliding action of recyclable materials. The guide rail portion is equipped with a rotatable, multi-row arranged rotating shaft, and the recyclable materials sliding down the guide rail portion on the rotating shaft include stumbling blocks for removing foreign objects.

[0014] According to the present invention, the rotating shaft is characterized in that it can realize the rotation of the suspension plate according to the weight of the recyclable material, and has more first elastic parts to impart elastic force to the suspension plate.

[0015] According to the present invention, the suspended pieces on the rotating shafts that are printed together are characterized by not overlapping each other.

[0016] According to the present invention, the two ends of the rotating shaft have bearing structures mounted on the guide portion, but the rotating shaft, the two ends, and the bearing structures also have elastic rotating portions.

[0017] According to the present invention, the elastic rotating portion is characterized by: receiving grooves formed at both ends of the rotating shaft and disposed separately along the circumferential direction of the rotating shaft; a mounting portion formed inside the bearing structure; a second elastic portion placed in the mounting portion; an elastic ball placed in the mounting portion and receiving the exposed portion in the receiving groove, and removed from the mounting portion by the second elastic portion.

[0018] According to the recyclable weight of the present invention, when a rotational torque is applied to the rotating shaft, the elastic ball placed on the receiving groove will be introduced into the placement part by the rotational torque. When the rotational torque applied to the receiving groove disappears, the elastic ball will be extracted from the placement part by the second elastic part and fixed on the receiving groove.

[0019] According to the present invention, the guide portion is characterized by having more screens provided at the lower part of the rotating shaft to filter out foreign matter discharged due to rejection by the foreign matter agent.

[0020] Invention Effects

[0021] According to the present invention, the recyclable material screening device for improving the yield is as follows: after screening aluminum cans, steel cans, etc. by the screening section, foreign objects attached to the recyclable material are removed for the first time by the collision of the collision wall and the recyclable material. After colliding with the collision wall, the recyclable material falls down along the surface of the agent, and at the same time, the foreign objects attached to the recyclable material are scraped off by the elastic tripping stone, thereby improving the efficiency of the material.

[0022] In addition, by improving the efficiency of foreign matter removal, the present invention can increase the yield by 10% to 20% or more compared with the existing yield during the recycling of screened canned goods.

[0047] To illustrate the operational advantages of the present invention and the objectives achieved by implementing the present invention, the following examples and references are made to the preferred embodiments of the present invention.

[0048] First, the terminology used in this application is merely for illustrating specific embodiments and is not intended to limit the invention. Multiple expressions may be included unless the singular expression clearly differs in meaning within the context. Furthermore, in this application, terms such as "comprising" or "having" should be understood to specify the presence of features, numbers, steps, actions, components, parts, or combinations thereof listed in the list, without excluding the possibility of the presence or addition of one or more other features or numbers, steps, actions, components, parts, or combinations thereof.

[0049] In describing this invention, detailed descriptions of the composition or function of the relevant announcements may be omitted if it is believed that such descriptions may obscure the essence of the invention.

[0050] like Figures 1 to 7 As shown, the recyclable material 1 screening device for improving the yield of the present invention includes a screening section 10 for recyclable material 1, a collision wall 20 and a foreign matter removal section 30.

[0051] According to the recyclable material 1 sorting device of the present invention, canned goods among various recyclable materials 1 are sorted before steel cans and aluminum cans are sorted.

[0052] Canned goods sorted in this way can be transported to the screening section 10 via conveyor belt 11 or other conveying means. During the transportation to the screening section 10, processes such as removing the contents of canned goods or sorting canned goods of other materials or other types of waste products can be carried out.

[0053] The canned goods sent to the screening section 10 through the aforementioned process or operation are screened by the screening section 10 according to whether they are steel cans or aluminum cans.

[0054] like Figure 1 , Figure 4 and Figure 6 As shown, the screening unit 10 according to the present invention is composed of recyclable materials 1 screened according to material.

[0055] In other words, the screening unit 10 will sort steel cans and aluminum cans from the recyclable material 1, i.e. canned goods. The screening work is first carried out by the first screening unit using magnetic force to classify steel cans, and then by the second screening unit using eddy current to screen aluminum cans.

[0056] Similarly, recyclable materials, namely aluminum or steel cans, selected by the various screening departments, can be supplied as impact walls.

[0057] In this configuration, the screening section 10 transports recyclable materials by the conveyor belt 11 and drive rollers 13 at both ends of the conveyor belt 11. The first and second screening sections can screen materials separately, while the recyclable materials moving on the conveyor belt 11 are supplied as the collision wall 20.

[0058] like Figure 1 , Figure 4 and Figure 6 As shown, according to the present invention, the collision wall 20 can remove foreign objects from the recyclable material 1 for the first time by colliding with the recyclable material 1 screened from the screening section 10.

[0059] The collision wall 20 is placed vertically in front of the screening section 10, causing the recyclable material 1 discharged from the screening section 10 to collide with it. In the case of the first screening section 10, as the magnetic force disappears, the steel cap may be discharged from the collision wall 20 as if flying, depending on the rotational force of the conveyor 11. In the case of the second screening section 10, the aluminum can is dragged by the eddy current generated by the magnetic field and discharged from the collision wall 20 as if flying.

[0060] Similarly, the recyclable material 1 discharged from the screening section 10 can first adhere to the foreign matter in the recyclable material 1 due to the impact generated by the collision with the collision wall 20, that is, the contents or water in the recyclable material 1 can be removed after falling off.

[0061] In this case, the upper end of the collision wall 20 may have a first upper end inner 21 formed by the side bending of the screening section 10. The first upper end inner 21 can prevent the recyclable material 1 discharged from the screening section 10 from hitting the upper end of the collision wall 20 and passing over the collision wall 20.

[0062] In addition, the lower part of the screening section 10 is also equipped with an inner wall 25 to prevent the foreign matter removal section 30 from being removed after the recyclable material 1 has been removed. That is, a foreign matter barrier 30 can be placed between the impact wall and the inner wall 25. In this case, after the recyclable material 1 discharged from the screening section 10 collides with the impact wall 20, it will fall to the foreign matter barrier 30. At this time, the recyclable material 1 that collided with the impact wall 20 will bounce back significantly, or the fallen recyclable material 1 will bounce back from the foreign matter barrier 30. The inner wall 25 can prevent the recyclable material 1 from bouncing back. In addition, the upper end of the inner wall 25 can be equipped with a second upper inner lining 25a, which can be bent outward to guide the recyclable material 1 falling from the screening section 10 in a straight downward direction to fall into the foreign matter removal section 30.

[0063] In addition, such as Figure 6 As shown, according to the present invention, guide wings 23 can be provided on both sides of the collision wall 20, and the guide wings 23 can be angle-adjustable. That is, the guide wings 23 are arranged at a certain angle at both ends of the collision wall 20, which can prevent the recyclable material 1 discharged from the screening section 10 from deviating from the lateral direction of the collision wall 20. In addition, while preventing the recyclable material 1 from falling off the collision wall 20, the guide wings 23 guide the recyclable material 1 to fall into the foreign matter removal agent 30, which can improve the efficiency of the device.

[0064] like Figures 1 to 5 As shown, the foreign object removal 30 specified in this invention is configured to be placed at the lower part of the collision wall 20, guide the falling recyclable material 1 to slide down after the collision, and scrape away the foreign object starting from the sliding recyclable material 1.

[0065] The foreign object removal device 30 can be composed of a guide part 31, a rotating shaft 32, and a suspension plate 33.

[0066] The guide section 31 of the foreign object removal unit 30 can be placed at the lower part of the collision wall 20 and tilted to guide the sliding action of the recyclable material 1. That is, if the recyclable material 1 falls on the collision wall 20, it will slide down along the slope of the guide section 31.

[0067] The rotating shaft 32 of the foreign matter removal unit 30 can rotate on the guide portion 31 and can be arranged in multiple rows. That is, the rotating shaft 32 can be arranged on the guide portion 31, with both ends rotatable, and can be arranged in a form orthogonal to the moving direction of the recyclable material 1.

[0068] Furthermore, the clips 33 of the foreign matter removal agent 30 are composed of pointed shapes, and multiple clips can be placed on each rotating shaft 32. Therefore, foreign matter or other debris attached to the downstream recyclable material 1 may be scratched by the clips 33, or the recyclable material 1 can be separated and removed from the bottom when it is attached to the clips.

[0069] In this case, to give the obstacle 33, which improves the efficiency of foreign object removal, an elastic part 34 may be provided. For example... Figure 2 As shown, the first elastic portion 34 can be composed of a spring placed on a stabilizing groove 35 formed on the rotating shaft 32. Additionally, the end of the suspension plate 33 can be equipped with a fixing protrusion 33a for engaging and fixing with the end of the spring in the first elastic portion 34. In this case, to prevent the spring from disengaging, it is preferable to equip the upper part of the fixing groove 35 with an inwardly protruding anti-disengagement portion (not shown). This anti-disengagement portion can be sized to accommodate the fixing protrusion 33a of the suspension plate 33.

[0070] Therefore, as Figure 5 As shown, the suspension plate 33 can rotate downwards according to the weight of the recyclable material 1 flowing out from the first elastic part 34. During this process, the suspension plate 33 can scrape off the surface of the recyclable material 1 by the elastic force of the first elastic part 34, thereby removing foreign objects attached to the recyclable material 1.

[0071] Furthermore, in order to improve the efficiency of removing foreign objects from the recyclable material 1 flowing out of the passenger guide 31, it is recommended that the suspension plates 33 be placed on adjacent rotating shafts 32 respectively. For example, taking the city of Road 1 as a reference, the suspension plates 33 placed on the rotating shaft 32 at the top and the suspension plates 33 placed on the rotating shaft 32 at the bottom are not on the same line as each other, but are staggered according to the direction of movement of the recyclable material 1.

[0072] Therefore, even if recyclable material 1 flows out between the suspension plates 33 placed on any one of the rotating shafts 32, the foreign matter can be removed by the suspension plates 33 placed on the next rotating shaft 32.

[0073] like Figure 3 As shown, the present invention has a bearing structure 40 supporting a rotating shaft 32, and the bearing structure 40 and the rotating shaft 32 may also have an elastic rotating pair 50.

[0074] First, the bearing structure 40 is placed on both sides of the guide portion 31 of the foreign matter removal section 30, and the two ends of the rotating shaft 32 are connected to support the rotating shaft 32.

[0075] Secondly, the elastic rotating part 50 may be composed of a receiving groove 51, a second elastic part 55, an elastic ball 57, and a placement part 53.

[0076] The receiving groove 51 of the elastic rotating part 50 can be formed along the circumferential surface at both ends of the rotating shaft 32. Furthermore, the receiving groove 51 can be formed by the number of suspension plates 33 placed on the rotating shaft 32; that is, assuming one suspension plate 33 is formed by four protrusions, the receiving groove 51 can be placed in the number and position corresponding to each protrusion. The mounting part 53 of the elastic rotating part 50 is formed in the form of a groove inside the bearing structure 40, and the second elastic part 55 of the elastic rotating part 50 can be built into the mounting part 53. Additionally, the elastic ball 57 of the elastic rotating part 50 can be mounted in the placement part 53 with the second elastic part 55 spring compressed. In this case, to prevent the elastic ball 57 from detaching from the placement part 53, only a portion of the elastic ball 57 is exposed outward from the placement part 53. That is, assuming the elastic ball 57 is a sphere, the exposed portion of the elastic ball 57, based on the city of the road 3, exposes only a portion of the lower half of the elastic ball 57, preventing the elastic ball 57 from flowing out of the placement part 53.

[0077] As described above, when the rotational torque applied to the rotating shaft 32 by the elastic rotating part 50 according to the weight of the recyclable 1 occurs, the elastic ball 57 placed in the receiving groove 51 can be elastically supported by the second elastic part 55 through the rotational torque and guided into the placement part 53. In this state, the elastic ball 57, whose rotational torque applied to the rotating shaft 32 has disappeared, is extracted from the placement part 53 by the elastic force of the second elastic part 55. The extracted elastic ball 57 can be placed in another receiving groove 51, stopping the rotation of the rotating shaft 32.

[0078] In other words, the elastic rotating part 50 is a structure designed to solve the problem of a large number of recyclable materials 1 accumulating on a rotating shaft 32 at the same time, where the accumulated recyclable materials 1 cannot be moved by the elastic action of the hanging piece 33 alone.

[0079] For example, when recyclable material 1 is sandwiched between the hanging objects 33 placed on a rotating shaft 32, or when the placement direction of the rotating shaft 32 is referred to as horizontal, if the recyclable material 1 is not arranged vertically, but is placed horizontally on multiple hanging objects 33, another phenomenon of recyclable material 1 supply backlog may occur.

[0080] In this situation, not only does moving recyclable material 1 become difficult, but the work of removing foreign objects will also be delayed.

[0081] To solve the aforementioned problem, when the aforementioned situation occurs, the elastic rotary joint 50, with its predetermined weight recognized by the recyclable material 1 by the rotating shaft 32, will exert a certain rotational torque on the rotating shaft 32. In this case, the elastic ball 57 placed on the receiving groove 51 is introduced into the placement part 53 by the rotational torque, thereby allowing the rotating shaft 32 to rotate. Thus, if the rotating shaft 32 rotates, the suspension plate 33 can also rotate, allowing the recyclable material 1 suspended on the suspension plate 33 to descend and slide down. In this case, the rotation range of the rotating shaft 32 can be such that if four receiving grooves 51 are formed at equal intervals in the circumferential direction of the rotating shaft 32 (the stumbling block 33 forms a protrusion at approximately 90 degrees), the rotation angle can be 90 degrees. That is, the rotation range of the rotating shaft 32 can be determined based on the number of receiving grooves 51 formed on the same circumferential surface of the rotating shaft 32. However, if the intervals between the receiving grooves 51 are uneven, the rotation angle of the rotating shaft 32 will vary depending on the distance between each receiving groove 51.

[0082] In order to eliminate this situation, the elastic rotary joint 50 can rotate the rotating shaft 32 by a certain angle to make the recyclable material 1 move smoothly, thereby improving work efficiency.

[0083] In particular, the elastic rotating part 50 should remain stationary when the recyclable material 1 is not accumulating and is flowing out normally, and when it removes foreign objects due to the elastic action of the clamping plate 33. Therefore, the rotation of the rotating shaft 32 of the elastic rotating part 50 may occur when a certain weight of recyclable material 1 is accumulating. In such cases, the accumulation may be caused by the recyclable material 1 clamping between the suspension plates 33 placed on one rotating shaft 32, or when the placement direction of the rotating shaft 32 is referred to as transverse, the recyclable material 1 is not arranged longitudinally but transversely, resulting in accumulation due to the suspension of multiple suspension plates 33, etc.

[0084] In this situation, the elastic effect generated by the suspension plate 33 may also fail to work. Therefore, by eliminating this situation through the elastic rotating part 50, work efficiency can be further improved.

[0085] Furthermore, according to the present invention, a fertilizer mesh 60 may be applied to the lower part of the foreign matter removal agent 30. That is, the fertilizer mesh 60 is for filtering foreign matter removed by the filter sheet 33, and may consist of a quadrangular frame 61 and a mesh network structure 63 mounted on the frame 61.

[0086] This is because the lower part of the foreign matter removal 30 is where the recyclable material 1, from which the foreign matter is removed, is loaded and collected. If the removed foreign matter falls out, it will reduce the efficiency of the foreign matter removal work. Therefore, filtering the foreign matter from the recyclable material 1 through the fertilizer net 60 can improve the efficiency of foreign matter removal and even the overall work efficiency.

[0087] As described above, the recyclable material sorting device according to the invention of this court, after sorting aluminum cans, steel cans, etc. by the sorting section, removes foreign objects attached to the recyclable materials in one go by colliding with the collision wall. In addition, after colliding with the collision wall, the recyclable materials fall down along the foreign object removal groove, and at the same time, the foreign objects attached to the recyclable materials are scraped off by the elastic hanging plate, thereby improving the foreign object removal efficiency.

[0088] In addition, by improving the efficiency of foreign matter removal, the present invention can increase the yield by 10% to 20% or more compared with the existing yield during the reuse of screened canned goods, that is, increase the yield from the existing 60% yield to 70% to 80%.

[0089] Similarly, the invention has been described with reference to one embodiment shown in the figures, but this is merely an example, and those with ordinary knowledge of the art will understand that various variations and other embodiments with uniformity can be achieved thereby.

[0090] Therefore, the true scope of protection of this invention should be determined based on the technical concept of the appended claims.
