Description

Technical Field

[0001] The invention relates to the technical field of aluminum alloy waste recycling, and in particular to a waste aluminum alloy material recycling device and a recycling method. Background Art

[0002] Aluminum alloy is an alloy formed by adding a certain amount of other alloy elements to aluminum as the main material. Aluminum alloy castings are usually recycled and reused after use. Existing recycling devices usually crush aluminum alloy waste first and then carry out smelting treatment. However, since the surface of aluminum alloy waste contains a large amount of impurities, direct smelting will produce more harmful gases. Therefore, the aluminum alloy waste needs to be cleaned before smelting to minimize the emission of harmful gases. For example, Chinese patent CN118218313B discloses an environmentally friendly crushing and cleaning device for aluminum alloy casting waste, which includes a processing box, a guide plate is tilted at the upper end of the box body, and a material-lifting mechanism is provided below the guide plate to prevent the aluminum alloy waste from clogging. A mesh cleaning cylinder is provided at the lower end of the box body, and a cleaning mechanism for cleaning the waste is provided in the cylinder, and a discharging mechanism for discharging is provided on one side of the cleaning cylinder. The invention uses the material-lifting mechanism to push the waste to prevent clogging, and stirs the waste through the cleaning mechanism to improve the cleaning effect. However, the device still has the following problems: 1. When the ejection mechanism ejects the material from the stencil, the two need to cooperate precisely. During this process, there is friction when the ejection needle clears the stencil. Long-term use will cause wear of the ejection mechanism and the stencil, thus affecting the service life of both.

[0003] 2. The cleaning mechanism has limited cleaning effect on aluminum alloy waste by stirring. Aluminum alloy materials are easily stacked on each other under the action of centrifugal force and accumulate on the filter net, resulting in incomplete cleaning.

[0004] 3. The screened materials will be crushed for the second time, but the crushed aluminum alloy waste will not be classified for the second time when entering the cleaning mechanism, which cannot ensure that the materials meet the process requirements, which may cause the screen to be blocked during subsequent sorting or cleaning.

[0005] 4. The equipment is large in size, which requires a high origin of the equipment, thereby increasing the recycling cost. Summary of the invention

The cleaning mechanism cooperates with the cleaning liquid and the rotating first blade to ensure that the material is thoroughly cleaned during the screening process. The spiral first blade can drive the aluminum alloy material to the first discharge port to avoid material accumulation and clogging the screen. The overall structure of the present invention is compact and optimizes space utilization. The remaining impurities can be further cleaned through the collection tank and the filter, improving the efficiency of the cleaning liquid, and ensuring that the cleaned aluminum alloy material meets the process requirements.

[0017] S2a. By driving the rotating shaft, the rotating shaft drives the rotation of multiple first blades, so that the scrap aluminum alloy materials falling into the screen from the feed port will enter the spiral channel formed by the first blades and the inner wall of the screen in sequence, and the spiral first blades can drive the scrap aluminum alloy materials in the screen to move along the axial direction of the rotating shaft until the scrap aluminum alloy materials are discharged from the first discharge port.

DETAILED DESCRIPTION

[0035] In order to further understand the features, technical means, specific objectives and functions of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0036] like Figures 1 to 5 , Figure 8 , Fig. 9 and Fig.11 As shown: A method for recycling waste aluminum alloy materials, comprising the following steps: S1. First, fill the cleaning liquid in the cleaning cylinder 1, and put the waste aluminum alloy materials to be processed into the screen 2 in the cleaning cylinder 1 through the feed port 21. The larger aluminum alloy materials in the waste aluminum alloy materials are sorted out and retained in the screen 2, and the smaller waste aluminum alloy materials pass through the screen 2 and the sieve holes 2211 on the first blade 221 and fall to the bottom of the cleaning cylinder 1.

[0037] S2a, driving the rotating shaft 22, and driving the rotation of multiple first blades 221 through the rotating shaft 22, so that the scrap aluminum alloy materials falling into the screen 2 from the feed port 21 will enter the spiral channel formed by the first blades 221 and the inner wall of the screen 2 in sequence, and the spiral first blades 221 can drive the scrap aluminum alloy materials in the screen 2 to move along the axial direction of the rotating shaft 22 until the scrap aluminum alloy materials are discharged from the first discharge port 11.

[0038] S2b. The rotating first blade 221 can stir the cleaning liquid to clean the waste aluminum alloy material in the screening process.

[0039] S3a, the waste aluminum alloy material falling into the bottom of the cleaning cylinder 1 is cleaned by the cleaning mechanism 12.

[0040] S3b, using the recovery assembly 13 above the cleaning cylinder 1 to recover the stains remaining on the surface of the cleaning liquid during the cleaning process of the aluminum alloy material by the cleaning mechanism 12.

[0041] First, fill the cleaning cylinder 1 with cleaning liquid, the liquid height of which is preferably half of the cleaning cylinder 1, and feed the crushed waste aluminum alloy material from the feed port 21 into the screen 2. At the same time, drive the rotating shaft 22, and drive the plurality of spiral first blades 221 to rotate through the rotating shaft 22. The aluminum alloy material is screened through the screen holes 2211 on the first blades 221 and the screen 2. At this time, the larger aluminum alloy material will remain in the screen 2, while the smaller aluminum alloy material will pass through the screen 2 and the screen holes 2211 and settle to the bottom of the cleaning cylinder 1. The rotation of the first blade 221 driven by the rotating shaft 22 can stir the cleaning liquid, and the aluminum alloy material can be preliminarily cleaned by stirring the cleaning liquid; since the first blade 221 is spiral, the aluminum alloy material entering the spiral channel can move toward the first discharge port 11 along the axial direction of the rotating shaft 22 under the action of the first blade 221, so that the aluminum alloy material can maintain a moving state and will not produce a stacking effect, thereby preventing the aluminum alloy material from clogging the screen 2. At the same time, due to the rotation of the first blade 221, the first blade 221 will not gather on the first blade 221 or the screen 2, and the aluminum alloy material will continue to rotate with the first blade 221. Under the action of gravity, the aluminum alloy material will not stack on the first blade 221, which solves the problem of aluminum alloy material stacking in the prior art, ensures the sorting effect of the sieve hole 2211 on the first blade 221 and the screen 2 for the aluminum alloy material, can effectively distinguish large and small sizes of aluminum alloy materials, improves the sorting accuracy, and ensures that aluminum alloy materials of different sizes are effectively distinguished. By re-cleaning the screened aluminum alloy material with the cleaning mechanism 12 provided at the bottom of the cleaning cylinder 1, the cleanliness of the surface of the aluminum alloy material can be effectively improved, ensuring the clean treatment of waste aluminum alloy materials. At the same time, the stains generated during the cleaning process will float on the surface of the cleaning liquid. In order to ensure that they will not affect the aluminum alloy material, they are recovered in time through the recovery component 13 above the cleaning cylinder 1 to avoid stains remaining on the surface of the cleaning liquid and prevent them from accumulating, ensuring that the cleaning liquid always maintains efficient cleaning capabilities, thereby extending the service life of the cleaning liquid and reducing the maintenance frequency. The automatic conveying and screening of aluminum alloy materials are achieved by cooperating with the rotating shaft 22 through the spiral first blade 221 and the rotating shaft 22, avoiding the problem of excessive volume of traditional equipment. This design makes the equipment structure more compact, optimizes space utilization, and is suitable for application scenarios with limited production sites.

[0042] like Figures 1 to 5 , Figures 7 to 10As shown: a waste aluminum alloy material recovery device, applied to the above-mentioned waste aluminum alloy material recovery method, the recovery device comprises a cleaning cylinder 1 and a screen 2 and a rotating shaft 22 arranged in the cleaning cylinder 1, the cleaning cylinder 1 is filled with a cleaning liquid; the screen 2 is a cylindrical structure, the screen 2 is provided with a feed port 21 passing through the cleaning cylinder 1, and the end of the cleaning cylinder 1 away from the feed port 21 is provided with a first discharge port 11; the rotating shaft 22 is rotatably arranged in the screen 2, and the rotating shaft 22 is coaxially arranged with the axis of the screen 2; the rotating shaft 22 is provided with a plurality of first blades 221 uniformly distributed around its axis, the plurality of first blades 221 all extend along the radial direction of the screen 2, and the first blades 221 are a spiral structure, and the plurality of first blades 221 are The blades 221 and the inner wall of the screen 2 form a plurality of spiral channels; the first blade 221 is provided with sieve holes 2211 that match the screen 2; a cleaning mechanism 12 for cleaning the screened aluminum alloy material is provided below the screen 2 in the cleaning cylinder 1; a recovery component 13 for recovering stains remaining on the surface of the cleaning liquid during the cleaning process of the aluminum alloy material by the cleaning mechanism 12 is provided above the cleaning cylinder 1; an extension plate 2212 is provided at one end of the first blade 221 away from the rotating shaft 22, and the cross-section of the extension plate 2212 is an arc-shaped structure, and a cleaning strip 2213 for scraping and cleaning the residual aluminum alloy material on the screen 2 during the rotation of the first blade 221 is provided on the edge of the extension plate 2212. By setting the cleaning strip 2213, during the rotation of the first blade 221, the cleaning strip 2213 can drive the aluminum alloy material between the screen 2 and the first blade 221, which not only prevents the aluminum alloy material from accumulating and clogging on the screen 2, but also ensures that the surface of the screen 2 always maintains permeability, thereby significantly improving the cleaning and screening efficiency. At the same time, the design of the cleaning strip 2213 can drive the aluminum alloy material on the screen 2 to move along the axial direction of the rotating shaft 22 toward the first discharge port 11 during the rotation of the first blade 221, thereby achieving smoother aluminum alloy material transportation and reducing stagnation.

[0043] In addition, the provision of the extension plate 2212 further strengthens the structure of the spiral channel and reduces the gap between two adjacent spiral channels, so that when the aluminum alloy material enters the screen 2 from the feed port 21, it can be evenly distributed in each spiral channel, avoiding excessive accumulation of the aluminum alloy material in the spiral channel. During the flipping process of the first blade 221, more aluminum alloy material will fall on the extension plate 2212, so that the first blade 221 can better drive the rotation and movement of the aluminum alloy material. The extension plate 2212 adopts an arc-shaped cross-section design, so that the first blade 221 and the screen 2 can maintain a precise fit, ensuring that the aluminum alloy material is more thoroughly cleaned and effectively sorted during the screening process. At the same time, this design also improves the structural strength of the first blade 221, extends the service life of the equipment, reduces the maintenance frequency, and improves the stability and efficiency of the overall operation.

[0044] It should be noted that the first blade 221 is provided with a mesh hole 2211 that matches the mesh 2, which means that the mesh hole 2211 on the first blade 221 and the mesh hole size of the mesh 2 are the same. Figures 3 to 5 , Figures 7 to 11 As shown: the rotating shaft 22 adopts a hollow structure, and a feed pipe 222 connected to the feed port 21 is provided on one end of the rotating shaft 22 near the feed port 21. The feed pipe 222 is used to transport external cleaning liquid to the inside of the rotating shaft 22. The rotating shaft 22 is provided with a plurality of nozzles 2221 surrounding its axis.

[0045] The cleaning liquid enters the hollow rotating shaft 22 through the feed pipe 222, and is uniformly sprayed out by a plurality of nozzles 2221 arranged on the rotating shaft 22. When the rotating shaft 22 drives the first blade 221 and the aluminum alloy material to rotate, the cleaning liquid sprayed by the nozzle 2221 fully contacts the rotating aluminum alloy material, achieving all-round cleaning of the aluminum alloy material. With the stirring of the cleaning liquid by the spiral first blade 221, it can not only cover the aluminum alloy material, but also further remove impurities and pollutants on the surface of the aluminum alloy material through the flushing effect of the sprayed liquid. At the same time, the nozzle 2221 also has the function of preventing the sieve hole 2211 and the screen 2 on the first blade 221 from being blocked. The setting of the hollow rotating shaft 22 not only increases the cleaning function, but also avoids the cumbersome design of adding additional spraying equipment in the traditional cleaning device, thereby reducing the complexity and volume of the equipment, and reducing the difficulty and cost of maintenance.

[0046] like Figures 3 to 5 , Figures 7 to 11 As shown: a collecting groove 14 protruding outward is provided at the bottom of the cleaning cylinder 1, the bottom surface of the collecting groove 14 is inclined, a discharge pipe 141 is provided at one end of the bottom of the collecting groove 14 close to the first discharge port 11, and the cleaning mechanism 12 is arranged on the collecting groove 14.

[0047] By setting the collecting tank 14, when the aluminum alloy material is cleaned in the cleaning cylinder 1, the aluminum alloy material screened by the screen 2 will gradually settle in the collecting tank 14 at the bottom of the cleaning cylinder 1. Since the bottom surface of the collecting tank 14 is designed to be inclined, the aluminum alloy material naturally gathers to the drainage pipe 141 at the bottom under the action of gravity, and is smoothly discharged out of the cleaning cylinder 1 through the drainage pipe 141. The cleaning mechanism 12 set on the collecting tank 14 can effectively remove the residual impurities on the aluminum alloy material in the collecting tank 14. The inclined bottom surface design allows the aluminum alloy material to be discharged quickly, avoiding the accumulation of aluminum alloy materials affecting the cleaning effect or causing poor equipment operation.

[0048] It should be noted that a valve is provided on the discharge pipe 141 to control the discharge of the aluminum alloy material. Meanwhile, the cleaning liquid will be lost when the aluminum alloy material is discharged, and a sufficient volume of cleaning liquid will always be maintained in the cleaning cylinder 1.

[0049] In other embodiments, Figures 3 to 5 , Figures 7 to 11 As shown: a semicircular filter screen 142 is arranged in the collecting tank 14, a driving shaft 143 coaxial with its axis is installed on the filter screen 142, a second blade 1431 surrounding its axis is arranged on the driving shaft 143, and the second blade 1431 is a spiral structure, and a second discharge port 15 is arranged on the cleaning cylinder 1 below the first discharge port 11.

[0050] During the cleaning process of the aluminum alloy material, the impurities contained in the aluminum alloy material will also enter the collecting tank 14, and the impurities are initially filtered through the semicircular filter 142. The aluminum alloy material is located on the filter 142, and the collecting tank 14 is used to collect the impurities. At this time, the driving shaft 143 is started, and the rotation of the driving shaft 143 drives the rotation of the second blade 1431. The aluminum alloy material in the filter 142 is pushed to the second discharge port 15 along the axial direction of the driving shaft 143 by the force of the second blade 1431, until the aluminum alloy material is discharged from the second discharge port 15, and the impurities of the aluminum alloy material are discharged from the drain pipe 141. Through the design of the semicircular filter 142, the aluminum alloy material and the impurities can be effectively separated, and the impurities and the aluminum alloy material are avoided. Mixing, ensure better cleaning effect. When the second blade 1431 rotates when the driving shaft 143, the aluminum alloy material on the filter 142 is automatically pushed to the second discharge port 15, realizing the automatic transportation and discharge of the aluminum alloy material, reducing manual intervention, and improving the automation level of the equipment. Impurities will be automatically discharged through the drain pipe 141 along with the cleaning liquid, reducing the impact of impurities on the cleaning process, avoiding blockage and impurity residue inside the equipment, and further improving the cleaning and separation efficiency. Through the separation and automatic discharge mechanism, the equipment can achieve continuous operation, reducing blockage and impurity accumulation during the cleaning process, thereby improving the operating stability of the equipment and reducing the failure rate. Through the effective separation of impurities and aluminum alloy materials, the wear of the equipment by impurities is prevented, the residual accumulation inside the equipment is reduced, the service life of the equipment is extended, and the maintenance and cleaning costs are reduced.

[0051] like Figures 1 to 7As shown: the first discharge port 11 and the second discharge port 15 are both provided with a lifting mechanism 16, and the lifting mechanism 16 includes a lifting bin 161, a transmission shaft 1611, a third blade 1612 and a first rotation drive motor 162. The lifting bin 161 is vertically arranged beside the cleaning cylinder 1, and the two lifting bins 161 are respectively provided with connecting pipes 163 connected with the first discharge port 11 and the second discharge port 15. The transmission shaft 1611 is rotatably arranged in the lifting bin 161, the third blade 1612 is a spiral structure, and the third blade 1612 is arranged around the axis of the transmission shaft 1611, and the bottom of the transmission shaft 1611 is provided with a first rotation drive motor 162 for driving it to rotate.

[0052] After the aluminum alloy material is discharged from the cleaning cylinder 1, it enters the lifting bin 161 through the connecting pipe 163, and the first rotating drive motor 162 is started. The first rotating drive motor 162 drives the transmission shaft 1611 connected to it, so that the transmission shaft 1611 starts to rotate, and drives the third blade 1612 around its axis to rotate. Since the third blade 1612 is a spiral design, the aluminum alloy material is gradually lifted upward under the push of the blade until the aluminum alloy material is transported to the top of the lifting bin 161 for discharge. The lifting mechanism 16 allows the aluminum alloy material to be continuously transported to a high place after discharge, which is suitable for further processing or discharge in multi-stage processing equipment, reducing interruptions and improving overall work efficiency. The aluminum alloy material in the screen 2 is sent to the crushing mechanism of the next process by the lifting mechanism 16 for secondary crushing, and then put into the screen 2 through the feed port 21 for secondary screening, while the aluminum alloy material at the bottom of the cleaning cylinder 1 is discharged from another lifting bin 161 through the second discharge port 15 and collected and sent for smelting.

[0053] Through the automatic rotation of the third blade 1612 and the transmission shaft 1611, the aluminum alloy material can be continuously transported without manual intervention, which greatly improves the automatic operation level of the equipment. The lifting bin 161 adopts a vertical structure, which occupies a small area, and the rotation of the third blade 1612 can save energy, thereby reducing the energy consumption generated during the transportation of the aluminum alloy material.

[0054] The design of the third blade 1612 can ensure that the aluminum alloy material is evenly distributed in the lifting bin 161 and is continuously pushed, thereby avoiding the accumulation or blockage of the aluminum alloy material and ensuring the stability of the equipment operation.

[0055] like Figures 1 to 7 As shown: the third blade 1612 is provided with a plurality of drain holes 16121 for draining the lifted aluminum alloy material, and the plurality of drain holes 16121 are evenly distributed on the surface of the third blade 1612 .

[0056] After the aluminum alloy material has passed the cleaning process in the cleaning cylinder 1, it often carries some cleaning liquid. During the lifting process, the drain hole 16121 on the third blade 1612 allows the residual cleaning liquid in the aluminum alloy material to be discharged downward through the drain hole 16121. As the aluminum alloy material moves upward, the residual cleaning liquid is gradually discharged to the bottom of the lifting bin 161, ensuring that the aluminum alloy material has completed the preliminary drainage treatment before being transported to the next processing step or discharged, reducing the amount of water carried, and providing good basic conditions for subsequent processes (such as drying, sorting, and smelting).

[0057] The setting of the drain hole 16121 will not affect the normal transportation of aluminum alloy materials. The aluminum alloy materials can be drained and transported synchronously during the lifting process, which improves the overall working efficiency of the equipment and reduces the additional dehydration process. This design enables the equipment to not only transport aluminum alloy materials, but also complete partial dehydration during transportation, further improving the versatility and automation level of the equipment, and improving the overall performance and production efficiency of the equipment.

[0058] It should be noted that the connection between the connecting pipe 163 and the first discharge port 11 and the second discharge port 15 of the cleaning cylinder 1 are sealed connection structures. This design ensures the fluid tightness between the lifting bin 161 and the cleaning cylinder 1, and forms an effective connection. Through this sealed connection, part of the cleaning liquid can smoothly flow into the bottom of the lifting bin 161, ensuring that the pressure difference between the cleaning cylinder 1 and the lifting bin 161 will not affect the smooth transportation of the aluminum alloy material. In this way, the aluminum alloy material can enter the lifting bin 161 from the cleaning cylinder 1 more smoothly and stably, ensuring that the aluminum alloy material will not be blocked or retained at the connection. With the design of the drain hole 16121 on the third blade 1612, the lifting bin 161 not only realizes the transportation of the aluminum alloy material, but also can effectively drain the aluminum alloy material during the lifting process. Through the sealed connection and draining treatment, the resistance of the aluminum alloy material during the transportation process is reduced, and the wear of the lifting bin 161 and the third blade 1612 is also reduced accordingly, thereby extending the service life of the equipment and reducing the frequency and cost of daily maintenance. The cleaning liquid discharged from the drain hole 16121 can flow back to the bottom of the lifting bin 161, and flow back to the collecting tank 14, and be discharged through the drain pipe 141, thereby realizing the effective recovery and recycling of the cleaning liquid, further reducing the consumption of the cleaning liquid and saving production costs.

[0059] like Figures 1 to 5 As shown: the recovery component 13 includes a liquid storage bin 131 for processing the recovered cleaning liquid, and a plurality of suction pipes 1311 are arranged on the liquid storage bin 131. The plurality of suction pipes 1311 all penetrate the cleaning cylinder 1 and are connected to the cleaning liquid inside thereof, and a first pipe 1312 connected to the feed pipe 222 is arranged on the liquid storage bin 131.

[0060] After the cleaning liquid is used in the cleaning barrel 1, stains will float on the surface of the cleaning liquid, which will affect the cleaning of the aluminum alloy material. To ensure the recycling of the cleaning liquid, multiple suction pipes 1311 are designed to penetrate the cleaning barrel 1 to collect the cleaning liquid in the barrel into the liquid storage bin 131, and the cleaning liquid is filtered and processed by the liquid storage bin 131 so that the cleaning liquid can be recycled. At this time, the treated cleaning liquid in the liquid storage bin 131 is connected to the feeding pipe 222 through the first pipe 1312, so as to realize the reflux and reuse of the cleaning liquid, ensure the recycling of the cleaning liquid, and thus reduce waste.

[0061] The suction tube 1311 can be configured as a retractable structure so that the suction tube 1311 can match the height of the liquid level of different cleaning liquids, thereby improving the adaptability of the equipment.

[0062] like Figures 1 to 5 As shown, the cleaning mechanism 12 includes a plurality of ultrasonic transducers 121 , and the plurality of ultrasonic transducers 121 are installed on the collecting tank 14 at equal intervals along the axial direction of the driving shaft 143 .

[0063] During the cleaning process, the ultrasonic transducer 121 applies ultrasonic vibrations to the cleaning liquid through a design that is evenly distributed on the collecting tank 14. These ultrasonic vibrations will generate a large number of tiny bubbles in the cleaning liquid. When the bubbles expand and burst rapidly in the liquid, the impact force generated can effectively remove impurities attached to the surface of the aluminum alloy material. The ultrasonic wave can also make the aluminum alloy material vibrate synchronously, and the impurities on the surface of the aluminum alloy are vibrated and separated. Through the continuous ultrasonic action, the cleaning effect can be further enhanced to ensure that the aluminum alloy material is cleaned more thoroughly. The addition of the ultrasonic transducer 121 significantly improves the efficiency and effect of the cleaning process. Through the physical action of the ultrasonic wave, the fine impurities that are difficult to clean on the surface of the aluminum alloy material can be effectively removed. At the same time, the ultrasonic cleaning method avoids mechanical damage to the aluminum alloy material and protects the structural integrity of the aluminum alloy material. This method can not only improve the cleaning accuracy, but also reduce the amount of cleaning liquid used in the cleaning process, reduce the cleaning cost, and extend the service life of the equipment. Different powers can be selected according to the cleanliness of the aluminum alloy material to clean it.

[0064] like Figures 1 to 5 As shown: a synchronous wheel 144 is provided on the driving shaft 143 and the end of the rotating shaft 22 close to the feed port 21, a synchronous belt 1441 is provided between the two synchronous wheels 144, and a second rotating driving motor 1442 is provided on the side of the driving shaft 143 for driving its synchronous wheel 144 to rotate.

[0065] When the second rotary drive motor 1442 is started, the output shaft of the second rotary drive motor 1442 drives the synchronous wheel 144 installed on the drive shaft 143 to rotate. Since the synchronous wheel 144 on the drive shaft 143 is connected to the synchronous wheel 144 on the rotating shaft 22 through the synchronous belt 1441, the power is transmitted to the rotating shaft 22, causing both to rotate synchronously at the same speed at the same time. The transmission of the synchronous belt 1441 can not only ensure that the drive shaft 143 and the rotating shaft 22 maintain a consistent movement speed, but also reduce the transmission efficiency loss caused by the mismatch of the rotation speeds of different shafts. The work efficiency during cleaning and transmission is improved, ensuring that the equipment can operate efficiently for a long time.

[0066] The above embodiments only express one or several implementation modes of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the protection scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
