Description

The structure of metal recyclables to reduce the volume of the revolving percussion device

This creation is about a structure of metal recycling objects produced by reducing the volume of metal recycling materials by using a whirling percussion device; in particular, it refers to a type of spheroid (or mass) that forms a wrinkled or sandwich structure of the recycled object. ) New structure.

Recycling metal (or stainless steel) scraps from waste incineration plants, using the high-temperature molten metal (or stainless steel) reclaimed materials of steel mills to form metal liquids to make metal (or stainless steel) recycled products, achieving recycling, environmental protection, and economy The topic of benefit, the department has learned skills. For example, Taiwan No. 82107709 "Method and device for continuous preheating of charge materials", the application of steelmaking raw materials mixed with waste incineration fly ash and other substances, and No. 90111315 "Recycling of waste incineration fly ash by electric arc furnace after reduction and oxidation procedures The "Utilized Steelmaking Method" patent case, etc., provides typical examples.

Traditional processing operations related to metal materials or scrap recyclables. Basically, metal recyclates recovered from combustion residues from garbage incineration sites have been burned at extremely high temperatures, so many impurities, chemical residues, dirty substances or other attachments will be embedded or attached to the surface or between the material interlayers. , These attachments not only cause the burden of transportation, but also cause difficulties in re-melting the material during the regeneration operation, which greatly increases the operating cost and reduces the value of reuse; therefore, the attachments must be removed before recycling. To separate these attachments, the traditional processing operations include shearing operations, cutting (or crushing, rolling) the stainless steel recycle into multiple smaller-volume primary bodies. In addition, the primary body is placed in an acidic agent, so that the acidic agent etches the primary body, dissociating part of the lifted attachments and performing cleaning operations, so that the primary body forms a flattened body with a smaller volume. In practice, the completed experience is delivered to the steel plant, and is placed in the furnace at the same time as the new metal raw materials in an appropriate proportion, melted into a metal liquid at high temperature, and then made into metal recycling products.

The above-mentioned issues related to the implementation and operational application of this kind of metal waste recycling and treatment operations are that in order to dissociate the attachments from the metal recycling material (or the primary body) as much as possible, the acidic agent must be used to etch the primary body for a long time. Increase the time and cost of processing operations.

As those who are familiar with this technique know, acidic agents can only dissociate the attachments on the surface of the finished body; therefore, there are still many attachments on the surface of the finished body. When the finished body is delivered to the steel plant, it is passed through the furnace. In the process of melting into liquid metal at high temperature, more ash and attachments will seriously hinder the melting operation of the recovered body, and after melting, these attachments will continue to be suspended on or melted into the molten metal Situation.

In order to improve or reduce the metal liquid impurities and avoid affecting the quality of metal recycled products, multiple slag removal operations must be performed in the overall operation; not only the operation is troublesome and time-consuming, but also the processing time and cost are increased. Not what we expected.

In particular, the metal recycling material mentioned above or the structural type in order to remove the attachments on the outer surface is a complete body structure in a loose (or larger surface area) state; therefore, the volume of transportation is greatly increased, making the The cost of transporting finished products to steel mills has increased significantly, thus significantly reducing the market value of recycled metal for reuse.

Typically, these reference materials show design skills related to metal (or stainless steel) waste or material recycling operations or treatment methods. If you reconsider the metal material recycling and processing operation, in its operation or technology, provide a processing device for dissociating impurities or attachments to change the structure of the entire metal material recycling; in fact, it will also significantly improve the conventional knowledge The processing time of skills and the quality of metal recycling products. These topics are not specifically taught or exposed in the above reference materials.

The main purpose of this creation is to provide a metal recycling structure that uses a percussion device to reduce the volume. The percussion device includes a body and a cavity defined by the body to accommodate the metal recycling (or primary body). The main body (or chamber) is equipped with a rotating shaft and a plurality of hammering bodies arranged around the revolving body on the rotating shaft. The hammering bodies can move with the rotation of the rotating shaft to perform percussive operations on the primary body to make the primary body The attachments are split or separated, and the outer edge or outer edge of the primary body is bent at least once to the inside of itself, forming wrinkles, sandwich structure (or reducing the distance between sandwiches) to form a reduced-volume spherical shape The body (or mass) structure (or terminal body) is beneficial to greatly reduce the transportation volume and improve the cleanliness of the recovered materials to shorten the subsequent melting operation time; effectively reduce the cost of the overall recycling operation and increase the reuse value.

According to the metal recyclable structure that uses the percussion device to reduce the volume of this creation, the primary body is formed into a regular and irregular contour structure. At least a first side, a second side connecting the first side, and a connection are defined The third side of the second side and/or the fourth side connected to the first side or the third side. The primary body is processed by the percussion device (or hammer body), so that the first side is bent toward the inside to form a first bending part, and the second side is bent toward the inside to form a second bending part and a third bending part. The side is bent toward the inside to form a third bending part and/or the fourth side is bent toward the inside to form a fourth bending part, so that the terminal body forms the above-mentioned reduced-volume spheroid (or mass) structure.

Please refer to Figures 1, 2 and 3, the metal recycling structure that uses the tapping device to reduce the volume of this creation is used in the metal (or stainless steel) scrap and metal recycling (or primary body) recovered from the waste incineration plant. Cooperate with the knocking device to form a new structure of metal recycling. The following description assumes that upper, top, lower, bottom, etc. are mentioned, and the direction shown in the figure is taken as the reference direction.

In the adopted embodiment, the percussion device is generally indicated by the reference number 30; it includes a cylindrical body 31, a base frame 32 supporting the body 31, and a feeding cover 60 arranged above the body 31; and a feeding cover 60 Provide metal recycling or primary materials to be processed. The main body 31 defines a cavity 33 and an opening 39 communicating with the cavity 33; the cavity 33 provides a working space for metal recyclables or the primary body 10. According to the direction shown in the figure, the bottom of the main body 31 (or the chamber 33) is provided with an arc panel 37 and a plurality of through holes 37a formed on the arc panel 37.

Figures 2 and 3 depict that the main body 31 can be divided into an upper part 31A and a lower part 31B; the upper part 31A and the lower part 31B can be opened by the operator to open the chamber 33, and the lower part 31B combines the base frame 32 and the main body 31 (or lower part 31B) Can be combined with a recovery chamber 55. And, the upper part 31A is provided with an opening 39 for allowing the primary body to enter the cavity 33. And, the upper part 31A is connected to the feeding cover 60; the feeding cover 60 is provided with a feeding port 61 and a dust exhaust channel 62.

Please refer to Figures 2, 3 and 4, the main body 31 (or chamber 33) is equipped with a revolving body 34, which can be rotated according to a rotating shaft 35, and a plurality of numbers are provided on the periphery of the revolving body 34 There are two rotatable hammer bodies 36, which can move with the rotation of the rotating shaft 35. In addition, the closest distance between the hammer 36 and the arc panel 37 can be set to be less than or equal to the diameter of the through hole 37a. Therefore, when the rotating shaft 35 is operated to rotate, the rotating shaft 35 drives the hammer body 36 to agitate or strike the primary body to further separate the attachments. And, in the continuous agitation or beating operation, the diameter of the recovered material or the primary body is reduced to no more than the through hole 37a, and can be output through the through hole 37a.

Therefore, Figure 5 shows that when the rotating shaft 35 is operated to rotate, the rotating shaft 35 drives the hammer body 36 to agitate or strike the primary body 10 inside the main body 31 (or chamber 33) to achieve further separation from the primary body 10. Out the role of attachment 20.

In detail, the rotating shaft 35 can be connected to a power source 40 (for example, a motor or the like is driven by a belt 41), so that the rotating shaft 35 can be reciprocated or rotated. The rotating shaft 35 is provided with a plurality of revolving bodies 34 arranged perpendicular to the rotating shaft 35 and a rod-shaped pivot portion 38 arranged on the peripheral area of the revolving body 34; and, the hammering body 36 may be regular ( Arrangement) The combination of the arrangement type and/or the irregular (arrangement) arrangement type is formed on the pivot part 38 to form a form that can move (for example, rotate or swing) freely according to the pivot part 38.

In the embodiment adopted, the revolving body 34 provided on the rotating shaft 35 defines a plurality of sections 50, and allows the hammer body 36 to be positioned in the section 50 to form a revolving motion according to the rotation of the rotating shaft 35. The pivoting portion 38 can also generate a rotation movement (for example, the situation depicted by the imaginary line in FIG. 4), which together form an additive multiplication effect to make the hammer body 36 produce an accelerated percussion effect on the metal reclaimed object or the primary body. The hammer bodies 36 in each section 50 are combined in a form arranged at an angle of 30 degrees (or 45 degrees) to 180 degrees.

Fig. 4 shows that each section 50 is equipped with at least two hammers 36, and the two hammers 36 are located at positions separated by 180 degrees. For example, the hammer 36 in the solid line part of Figure 4 is located at 0 degrees and 180 degrees; the dotted line shows the configuration of the hammer 36 in the adjacent section 50, which is located at 90 degrees and 270. Degree position. The configuration of the hammer body 36 may reduce the situation that the hammer body 36 moves or strikes the primary body, which causes movement interference and affects the smoothness of the work.

It can be understood that the configuration of the hammer body 36 allows the metal reclaimed object or the primary body to continuously receive impacts from different circumferential positions and different contact points (and/or contact directions), so that the metal reclaimed object is in the chamber. The complicated throwing (movement) direction is generated in 33, which can make the primary body get a uniform impact probability on the periphery of the primary body due to the above-mentioned complicated impact throwing route, and make the peripheral areas of the primary body uniformly converge in the inner direction. effect.

FIG. 4 also reveals that the hammer body 36 is provided with a pivot hole 36 a for combining the pivot portion 38. The pivot hole 36a is larger than the cross-sectional area of the pivot portion 38, so that after the hammer body 36 is installed on the pivot portion 38, the hammer body 36 is hung on the pivot portion 38, so that the hammer body pivot hole A gap 70 is formed between 36a and the pivotal portion 38, which can prevent the hammer 36 from being affected by the primary body between the inner wall of the chamber 33 (or the revolving body 34) and the hammer 36 during the rotation and percussion process of the hammer 36 The excessive squeezing of the squeeze, resulting in a stuck situation; and the hammer body 36 can rotate with the rotating shaft 35 to form a function similar to a hanging hammer structure, continuously hitting the metal reclaimed object or the primary body.

Please refer to Figure 5, when the rotating shaft 35 is operated to rotate, the metal recyclate or the primary body 10 can fall into the chamber 33 through the feeding port 61 and the opening 39; and the rotating shaft 35 drives the revolving body 34 to rotate to make the hammering body 36 revolves according to the rotating shaft 35, and uses the pivoting part 38 as a fulcrum (combined) to generate a compound rotation effect of self-rotation, agitating and hitting the primary body 10, or/and causing the primary bodies 10 to collide with each other to attach to the primary body 10. Attachments 20 such as coarse dust on the surface are cracked or peeled off and separated.

It should be noted that the operation of agitating and striking the primary body 10 and the primary body 10 against each other by the hammer body 36 will cause the surface attachment 20 of the primary body 10 to be impacted, ruptured and separated, and fall off. The interaction between the hammer body 36 and the arc panel 37 of the chamber 33 causes the outer edge or outer edge (or peripheral area) of the primary body 10 to continuously bend (or form wrinkles) in the inner direction during the throwing impact. The terminal body 100 is formed with a pleated, sandwich) structure, or by reducing the spacing between the layers to reduce the volume.

And, the aperture of the through hole 37a of the cavity 33 can establish a restriction for the volume of the terminal body 100 to pass through and exit the cavity 33, and the volume of the terminal body 100 that finally exits the cavity 33 must be reduced to pass through. The through hole 37a is used as a reference, and the terminal body 100 is allowed to exit the body 31 (or chamber 33) from the through hole 37a and fall into the recovery chamber 55 to allow the terminal body 100 to be delivered to the steel plant for high-temperature melting in the steel plant’s furnace. Liquid metal, made of recycled metal products.

It can be understood that the coarse dust and other attachments 20 adhering to the surface of the primary body 10 are separated due to the cracks or peeling of the above-mentioned operations, and a cleaner terminal body 100 is obtained. Compared with the terminal body 100, the terminal body 100 is melted at a high temperature in a steel mill furnace. The metal liquid process significantly reduces the situation of ash slag and attachments 20 suspended on the metal liquid, and improves the troublesome, time-consuming, and increased processing time and cost of multiple slag removal operations by conventional personnel; at the same time; , It can reduce the impurities in the liquid metal and improve the quality of recycled metal products.

Please refer to Figure 6A, which depicts the structure of the primary body 10. The primary body 10 has a regular and irregular contour structure, and at least defines a first side 11, a second side 12 connected to the first side 11, a third side 13 connected to the second side 12, and/or connection The fourth side 14 of the first side 11 or the third side 13.
