Description

Technical Field

[0001] The invention relates to the technical field of metal powder granulation, in particular to a magnesium alloy spherical particle forming device and a forming process thereof. Background Art

[0002] Magnesium alloys are widely used in a variety of fields, including automobiles, aerospace, electronic equipment, and daily necessities, due to their light weight, high strength, and excellent mechanical properties. Spherical magnesium alloys have unique advantages in specific applications, such as good fluidity, strong filling capacity, and easy processing.

[0003] For example, the patent document with the prior art announcement number CN219357938U discloses a spherical particle forming machine for tin and tin alloys, which relates to the field of granulation equipment for metal liquid phase forming. It includes a spheroidizing molder, a dropper arranged on the spheroidizing molder and a melting furnace arranged on the dropper. The upper end face of the spheroidizing molder is provided with a feed port, and the spheroidizing molder is provided with a accommodating cavity. It also includes a water supply box and a cooling box arranged on the water supply box. The spheroidizing molder is provided with a water cooling pipe, and the water cooling pipe is provided with a water inlet. The water supply box is provided with a connecting pipe, and the water cooling pipe is provided with a water outlet. The connecting pipe is provided with a water pump. The cooling box is located above the water supply box, and a through hole is provided at the bottom of the cooling box. An adjusting mechanism is provided in the cooling box. Water is transported to the water cooling pipe through the connecting pipe to cool the mixed oil. Compared with the compressor, the energy consumption of the water pump is lower, thereby reducing the energy consumption required for cooling the mixed oil.

[0004] Although the above-mentioned prior art is designed with a cooling box to effectively cool the mixed oil, there is a significant shortcoming in the actual application scenario. Specifically, after the material released by the dropper passes through the porous screen, it directly contacts the mixed oil below for shaping. However, during this falling process, the material may fall into the mixed oil in a variety of different postures or angles, which leads to different shaping effects of the material in the mixed oil, and thus makes the overall forming rate low. This inconsistent falling posture not only affects the uniformity and regularity of the spherical particles, but may also lead to a decrease in production efficiency and fluctuations in product quality. To this end, the present application proposes a magnesium alloy spherical particle forming device and a forming process thereof. Summary of the Invention

[0012] Preferably, the drive assembly includes a blade rotatably connected to the inside of the sieve plate, and one end of the side tube extends to one side of the blade. The bottom of the push plate is fixedly connected to a swivel that is slidably connected to the sieve plate, and the bottom of the swivel is fixedly connected to a plurality of connecting pieces that can interfere with the blade.

[0013] Preferably, a bracket for supporting the centrifugal cylinder is fixedly connected to the bottom of the pressurized box, a third motor for driving the centrifugal cylinder to rotate is fixedly connected to the bottom of the bracket, and a limiting rod is fixedly connected to one side of the bracket.

[0014] Preferably, the air source assembly includes a plurality of air cylinders fixedly connected to the inside of the material receiving box, the tops of the plurality of air cylinders are slidably connected with piston spring rods adapted thereto, and the tops of the plurality of piston spring rods are fixedly connected to the bottom of the buffer rubber pad, and one side of the plurality of air cylinders is connected to a connecting pipe connected to the rolling plate.

[0018] The present invention also provides a magnesium alloy spherical particle forming process, comprising the following steps:

[0019] S1. When in use, the metal powder is first cleaned and impurity-removed and then poured into the hopper. The magnesium alloy powder raw material in the hopper is poured into the interior of the electric heating feed pipe. Then, the powder raw material is heated and transported to the interior of the pressurized box, and passes through the forming orifice plate to form the mold;

[0020] S2. At the same time, the air ring is inflated inside, and the pre-cooling pipe and the screen plate are exhausted alternately under the operation of the regulating component. At the same time, the push plate pushes the material that has not been screened under the action of the driving component;

[0021] S3, the screened material falls through the screen plate and enters the interior of the centrifuge for shaping;

[0022] S4. When the spherical particles fall into the receiving box, they will first hit the buffer rubber pad and be buffered. Under the operation of the air source component, the air outlet holes on the rolling plate will exhaust gas to cool and remove dust from the materials.

[0023] Compared with the prior art, the present invention has the following beneficial effects:

[0024] An electrically heated heating wire inside the feed pipe rapidly heats the metal powder to a molten state, where it is evenly conveyed to the pressurizing box by feed vanes. A pneumatic cylinder drives the pressing plate downward, forcing the molten material through the forming orifice plate, forming preliminary spherical particles. The entire process is efficient and continuous, significantly improving production efficiency. A cutting disc on the hollow rotating rod, driven by a second motor, rotates, precisely cutting the material passing through the forming orifice plate, ensuring that each spherical particle meets the required size and shape. The cutting process is stable and reliable, reducing material waste and rejects. An air pump delivers air to the air collar through the air pipe. A regulating assembly intelligently changes the airflow direction based on the rotation of the hollow rotating rod. As the cutting disc cuts the material, the airflow is directed inside the hollow rotating rod for primary cooling of the freshly cut material, preventing it from re-adhering. Once cutting is complete, the airflow is directed inside the sieve plate for secondary cooling of the material passing through the sieve plate, preparing it for subsequent shaping. This intelligent cooling method not only improves material cooling efficiency but also ensures the quality and stability of the spherical particles. The screen plate screens the cut material, ensuring only qualified spherical particles pass through. The drive assembly uses airflow to move the push plate, removing unqualified material that has not passed through the screen plate to one side of the pressurized box for storage. This automated screening and cleaning method reduces manual intervention, improving production efficiency and product quality.

[0025] The centrifugal drum further shapes the spherical particles. The centrifugal force generated by their rotation causes them to gradually form more regular spheres through rolling, friction, and collision, improving the roundness and surface quality of the product. Furthermore, the dual screening mechanism of the drum and sieve ensures that only spherical particles that meet the required standards are discharged, effectively preventing oversized or undersized particles from entering the finished product, further enhancing product quality. A rubber cushion inside the receiving bin effectively catches and cushions spherical particles as they fall from the drum, minimizing damage from inter-particle collisions. The compression of the cushion drives the piston spring rod inside the cylinder, pushing gas through a connecting pipe to the rolling plate, where it is ejected through the outlet port for final cooling and dust removal. This design not only improves cooling efficiency but also ensures surface cleanliness of the spherical particles, facilitating subsequent packaging and transportation. A one-way air inlet valve allows external air to enter the cylinder without allowing internal gas to escape, achieving one-way gas flow and recycling. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0042] Example 1: Please refer to Figure 1 、 Figure 2 as well as Figure 4The present invention provides a technical solution: a magnesium alloy spherical particle forming device, comprising a hopper 100 filled with metal powder, an electrically heated feeding pipe 101 connected to the bottom of the hopper 100 and a pressurizing box 104 connected thereto, a forming orifice plate 107 for forming is fixedly connected to the interior of the pressurizing box 104, a sieve plate 108 is provided in the pressurizing box 104, a cylinder 105 is fixedly connected to the top of the pressurizing box 104, a pressing sheet 106 is fixedly connected to the output end of the cylinder 105, and a feeding vane is rotatably connected to the interior of the electrically heated feeding pipe 101. The bottom of the electric heating feed pipe 101 is provided with a first motor 102 for driving the feed blade 103 to rotate. The internal structure of the electric heating feed pipe 101 is provided with an electric heating wire that can heat the metal powder in the electric heating feed pipe 101 to a molten state, and transport it to the inside of the pressurizing box 104 through the feed blade 103. As the driving cylinder 105 runs, the pressing plate 106 is operated to move downward and pressurize the molten material through the forming orifice plate 107, and the sieve plate 108 can be used for screening, and the metal powder can be cleaned and decontaminated. Common cleaning methods include solvent cleaning, ultrasonic cleaning, etc. Through cleaning, the oil and impurities on the surface of the powder can be removed, and the purity and surface activity of the powder can be improved. Then the metal powder is placed in the hopper 100.

[0043] See also Figure 3 、 Figure 5 as well as Figure 6 , and also includes a hollow rotating rod 200, which is arranged inside the pressurized box 104 and has a plurality of cutting blades 201 fixedly connected to the top of the hollow rotating rod 200 for cutting materials. The interior of the hollow rotating rod 200 is evenly connected with a plurality of pre-cooling pipes 202. The outer surface of the sieve plate 108 is fixedly connected with an air collar 204, and the interior of the air collar 204 is provided with an adjusting component for changing the direction of the airflow. By setting the adjusting component, the direction of the airflow can be changed, thereby achieving multiple cooling and improving subsequent shaping, wherein the cutting blade 201 can cut the material passing through the forming orifice plate 107 and separate the spherical particles.

[0044] See also Figure 7 、 Figure 8 as well as Figure 9The adjusting component includes a rotating shaft 208 rotatably connected to the top of the air sleeve 204, a trigger plate 209 is fixedly connected to the top of the rotating shaft 208, and a pull handle 210 is fixedly connected to the bottom of the rotating shaft 208. The internal rotation of the air sleeve 204 is connected to a lever 212 that is rotatably connected to the pull handle 210. A torsion spring is provided at the connection between the air sleeve 204 and the lever 212. A double-headed piston rod 211 is rotatably connected to the bottom of the lever 212 inside the air sleeve 204. One end of the air sleeve 204 is connected to a side pipe 213. The bottom of the pressurizing box 104 is fixedly connected to an air pump 206. The output end of the air pump 206 is connected to an air supply pipe 207 that is connected to the air sleeve 204. By setting the air pump 206, air can be continuously supplied to the air sleeve 204. When the cutting disc 201 is used to cut the material During cutting, the regulating component operates to direct the gas to the interior of the hollow rotating rod 200, so that the airflow blows toward the material just cut, cooling the material initially to prevent it from sticking together again. When the cutting is completed, the cutting blade 201 will be stationary, and then the regulating component will direct the gas in the gas collar 204 to the interior of the sieve plate 108, so that the material passing through the sieve plate 108 is disturbed by the airflow again for subsequent cooling. In this case, under the action of the torsion spring, the lever 212 has one end of the double-headed piston rod 211 in its initial state away from the interior of the side tube 213, and the other end of the double-headed piston rod 211 is placed inside the gas collar 204, so that the gas in the gas collar 204 cannot enter the interior of the hollow rotating rod 200, but the gas in the gas collar 204 enters the interior of the side tube 213.

[0045] Among them, the outer surface of the hollow rotating rod 200 is fixedly connected with an arc-shaped piece 205 that can interfere with the trigger piece 209, and the bottom of the pressurizing box 104 is fixedly connected with a second motor 203 that drives the hollow rotating rod 200 to rotate. A connecting groove 218 is opened on the outer surface of the hollow rotating rod 200. The arc-shaped piece 205 can follow the rotation of the hollow rotating rod 200 and drive the adjustment component to operate so that the gas in the air ring 204 is transported to the inside of the hollow rotating rod 200.

[0046] See also Figure 9 、 Figure 10 as well as Figure 11A push plate 217 is provided above the sieve plate 108, and a driving assembly for driving the push plate 217 to move is provided inside the sieve plate 108. The driving assembly includes a blade 214 rotatably connected to the inside of the sieve plate 108, and one end of the side tube 213 extends to one side of the blade 214. The bottom of the push plate 217 is fixedly connected to a swivel 215 slidably connected to the sieve plate 108, and the bottom of the swivel 215 is fixedly connected to a plurality of connecting pieces 216 that can contact the blade 214. As the gas enters the interior of the sieve plate 108, the blade 214 rotates and pushes the swivel 215 to rotate, thereby driving the push plate 217 to move continuously, which causes the unqualified materials that have not passed through the sieve plate 108 to be swept away, thereby cleaning them to one side of the pressurized box 104 for storage.

[0047] It is worth mentioning that the air pump 206 runs for a long time, while the second motor 203 runs intermittently. Whenever the second motor 203 runs to drive the hollow rotating rod 200 to rotate, its arc-shaped piece 205 will push the trigger piece 209 to move and drive the adjustment component, so that the gas in the air ring 204 is guided to the inside of the hollow rotating rod 200 to pre-cool the cut material. When the hollow rotating rod 200 is stationary, the gas in the air ring 204 will be transported to the inside of the screen plate 108 to perform secondary cooling on the screened material, which allows the same batch of materials to be cooled twice. The initial cooling can prevent the cut materials from sticking together again, and the second cooling can further reduce the temperature to prepare for subsequent shaping while driving the push plate 217 to move.

[0048] Specifically, when in use, the magnesium alloy powder raw material in the hopper 100 is first poured into the interior of the electrically heated feeding pipe 101, and then the first motor 102 is started to drive the feeding blade 103 to rotate, so that the powder raw material is heated and at the same time conveyed to the interior of the pressurizing box 104 through the feeding blade 103, and then the cylinder 105 is driven to drive the pressing sheet 106 to move downward so that the molten material passes through the forming hole plate 107 to form, and then the second motor 203 is driven to rotate and drive the hollow rotating rod 200 to rotate so that the cutting blade 201 rotates to cut the raw material passing through the forming hole plate 107, and the cut material will be screened by the sieve plate 108, and at the same time, the air pump 206 is turned on and conveyed to the interior of the air sleeve 204 through the air pipe 207, wherein when the hollow rotating rod 200 is stationary, the gas in the air sleeve 204 will be conveyed through the side pipe 213 The feeding blade 214 rotates, causing the blade 214 to continuously hit the connecting piece 216, thereby driving the rotating ring 215 to rotate and then driving the push plate 217 to rotate, so that the push plate 217 pushes the unscreened material. At the same time, the air flow will also flow through the inside of the sieve plate 108 to cool the material passing through the sieve plate 108. At the same time, when the hollow rotating rod 200 rotates to transmit the cutting blade 201, the arc-shaped piece 205 will rotate together with the hollow rotating rod 200 and push the trigger piece 209 to move, so that the pull handle 210 pushes one end of the lever 212 to move, thereby changing one end of the double-headed piston rod 211 to approach the side tube 213, so that the gas in the air collar 204 passes through the air collar 204 and through the connecting groove 218 to irritate the interior of the hollow rotating rod 200, and then the gas is ejected through the air collar 204 to perform preliminary cooling on the just-cut material to prevent it from sticking.

[0049] In summary, the metal powder is rapidly heated to a molten state by the electric heating wire in the electrically heated feed pipe 101, and is evenly transported to the pressurized box 104 by the feed blades 103. The cylinder 105 drives the pressing plate 106 to press down, extruding the molten material through the forming orifice plate 107 to form a preliminary spherical particle shape. The entire process is efficient and continuous, significantly improving production efficiency. The cutting blade 201 on the hollow rotating rod 200 rotates under the drive of the second motor 203, and accurately cuts the material passing through the forming orifice plate 107 to ensure that the size and shape of each spherical particle meet the requirements. The cutting process is stable and reliable, reducing material waste and the production of defective products. The air pump 206 delivers gas to the air sleeve 204 through the air pipe 207, and the regulating component intelligently changes the direction of the airflow according to the rotation state of the hollow rotating rod 200. When the cutting blade 201 cuts the material, the airflow is directed to the inside of the hollow rotating rod 200, and the newly cut material is cooled for the first time to prevent it from sticking together again. After cutting is completed, the airflow is directed to the inside of the sieve plate 108 to perform secondary cooling on the material passing through the sieve plate 108 in preparation for subsequent shaping. This intelligent cooling method not only improves the cooling efficiency of the material, but also ensures the quality and stability of the spherical particles. The sieve plate 108 screens the cut material to ensure that only qualified spherical particles pass through. The drive assembly uses airflow to drive the push plate 217 to move, and the unqualified materials that have not passed through the sieve plate 108 are cleaned to one side of the pressurized box 104 for storage. This automatic screening and cleaning method reduces manual intervention and improves production efficiency and product quality.

[0050] Example 2: Please refer to Figure 12 、 Figure 13 as well as Figure 14 The present invention also provides a technical solution, which is different from the technical solution of embodiment 1: a magnesium alloy spherical particle forming device, which also includes a centrifugal cylinder 300, which is used to shape the formed magnesium alloy spherical particles. The bottom of the pressurizing box 104 is fixedly connected to a bracket 301 for supporting the centrifugal cylinder 300, and the bottom of the bracket 301 is fixedly connected to a third motor 302 for driving the centrifugal cylinder 300 to rotate. One side of the bracket 301 is fixedly connected to a limiting rod 303. By setting the centrifugal cylinder 300, the spherical particles can be caught and rotated under the drive of the third motor 302. During the rolling, friction and collision process on the centrifugal cylinder 300, the spherical particles gradually form spheres and are then discharged under the action of centrifugal force. At the same time, the screen plate 108 can screen out oversized spherical particles, and the centrifugal cylinder 300 can screen out oversized spherical particles, so that spherical particles that meet the standards are discharged.

[0051] The bottom of the buffer rubber pad 401 is provided with an air source assembly for supplying air to the air outlet holes 404, and the air source assembly includes a plurality of air cylinders 405 fixedly connected to the inside of the material receiving box 400, and the tops of the plurality of air cylinders 405 are slidably connected to piston spring rods 407 adapted thereto, and the tops of the plurality of piston spring rods 407 are fixedly connected to the bottom of the buffer rubber pad 401, and one side of the plurality of air cylinders 405 is connected to a connecting pipe 406 connected to the rolling plate 403, wherein the buffer rubber pad 401 can catch the spherical particles and thereby cushion them, and in cooperation with the air source assembly, the spherical particles can be subjected to a final cooling treatment, and the dust on their surface can be treated at the same time.

[0052] Among them, one side of multiple air cylinders 405 is fixedly connected with a one-way air intake valve 408, the buffer rubber pad 401 and the rolling plate 403 are both constructed as inclined surfaces, and a discharge trough 402 is provided on one side of the material receiving box 400. The setting of the inclined surface can guide the movement of the spherical particles so that they can be discharged smoothly. The one-way air intake valve 408 allows external gas to enter the air cylinder 405, while the gas in the air cylinder 405 cannot be discharged through the one-way air intake valve 408.

[0053] Specifically, the sieved material falls through the sieve plate 108 and enters the interior of the centrifuge cylinder 300. Turning on the third motor 302 can drive the centrifuge cylinder 300 to rotate, so that the material in the centrifuge cylinder 300 generates centrifugal force, causing the material to continuously roll and form a sphere, which is separated from the centrifuge cylinder 300 by the centrifugal force and falls into the interior of the receiving box 400. The spherical particles falling into the receiving box 400 will first hit the buffer rubber pad 401 for buffering. At this time, the buffer rubber pad 401 will be impacted and squeeze the piston end of the piston spring rod 407 to slide inside the air cylinder 405, thereby pushing the gas in the air cylinder 405 to be transported to the interior of the rolling plate 403 through the connecting pipe 406, and finally ejected through multiple air outlet holes 404, for the final cooling and dust removal of the spherical particles on the rolling plate 403.

[0054] In summary, the provision of the centrifugal cylinder 300 provides further shaping for the spherical particles. Through the centrifugal force generated by rotation, the spherical particles gradually form more regular spheres during rolling, friction, and collision, thereby improving the roundness and surface quality of the product. At the same time, the dual screening mechanism of the centrifugal cylinder 300 and the screen plate 108 ensures that only spherical particles that meet the standards can be discharged, effectively preventing oversized or undersized particles from being mixed into the finished product, further improving product quality. The buffer rubber pad 401 inside the receiving box 400 can effectively catch the spherical particles that fall from the centrifugal cylinder 300, provide preliminary buffering, and reduce collision damage between particles. The compressive deformation of the buffer rubber pad 401 drives the piston spring rod 407 to slide in the air cylinder 405, thereby pushing the gas through the connecting pipe 406 to the rolling plate 403, and ejecting it through the air outlet 404, performing the final cooling and dust removal treatment on the spherical particles. This design not only improves the cooling efficiency, but also ensures the cleanliness of the surface of the spherical particles, providing convenience for subsequent packaging and transportation. The setting of the one-way air inlet valve 408 ensures that external gas can smoothly enter the air cylinder 405, while the gas in the air cylinder 405 cannot be discharged through the one-way air inlet valve 408, thereby realizing the one-way flow and recycling of the gas.

[0055] Example 3: Please refer to Figures 1 to 14 The present invention also provides a technical solution, which is different from the technical solution of embodiment 1: a magnesium alloy spherical particle forming process, comprising the following steps:

[0056] S1. When in use, the magnesium alloy powder raw material in the hopper 100 is first poured into the interior of the electrically heated feeding pipe 101, and then the first motor 102 is started to drive the feeding blade 103 to rotate, so that the powder raw material is heated and simultaneously conveyed to the interior of the pressurizing box 104 through the feeding blade 103. Then, the cylinder 105 is driven to drive the pressing plate 106 to move downward so that the molten material passes through the forming orifice plate 107 to form. Then, the second motor 203 is driven to rotate and drive the hollow rotating rod 200 to rotate so that the cutting blade 201 rotates to cut the raw material passing through the forming orifice plate 107. The cut material will pass through the sieve plate 108 for screening;

[0057] S2, at the same time, start the air pump 206 and deliver the gas to the inside of the air ring 204 through the air pipe 207, wherein when the hollow rotating rod 200 is stationary, the gas in the air ring 204 will pass through the side pipe 213 to deliver the blades 214 to rotate, so that the blades 214 continuously hit the connecting piece 216, thereby driving the rotating ring 215 to rotate and then driving the push plate 217 to rotate, so that the push plate 217 pushes the unscreened material, and at the same time, the air flow will also flow through the inside of the sieve plate 108 to cool the material passing through the sieve plate 108, and at the same time, the hollow When the rotating rod 200 rotates to transmit the cutting blade 201, the arc-shaped blade 205 rotates along with the hollow rotating rod 200 and pushes the trigger blade 209 to move, so that the pull handle 210 pushes one end of the lever 212 to move, thereby changing one end of the double-headed piston rod 211 to move close to the side tube 213, so that the gas in the gas collar 204 passes through the gas collar 204 and the connecting groove 218 to irritate the interior of the hollow rotating rod 200. Then the gas is ejected through the gas collar 204 to preliminarily cool the material just cut to prevent it from sticking.

[0058] S3: The sieved material falls through the sieve plate 108 and enters the interior of the centrifuge cylinder 300. The third motor 302 is turned on to drive the centrifuge cylinder 300 to rotate, generating centrifugal force on the material in the centrifuge cylinder 300. The material continuously rolls and forms a spherical shape. The spherical material falls out of the centrifuge cylinder 300 and falls into the interior of the material receiving box 400 due to the centrifugal force.

[0059] S4. When the spherical particles fall into the receiving box 400, they will first hit the buffer rubber pad 401 and be buffered. At this time, the buffer rubber pad 401 will be impacted and squeeze the piston end of the piston spring rod 407 to slide inside the air cylinder 405, thereby pushing the gas in the air cylinder 405 to be transported to the inside of the rolling plate 403 through the connecting pipe 406, and finally ejected through multiple air outlet holes 404 to perform the final cooling and dust removal on the spherical particles on the rolling plate 403.

[0060] In summary, the magnesium alloy powder raw material in the hopper 100 is continuously fed in through the electrically heated feed pipe 101. The feed blade 103 driven by the first motor 102 not only heats the raw material but also transports it to the pressurizing box 104, thereby achieving efficient and continuous raw material supply. The molten raw material in the pressurizing box 104 is formed into a preliminary shape by the forming orifice plate 107. Subsequently, the hollow rotating rod 200 driven by the second motor 203 drives the cutting blade 201 to rotate, thereby achieving automated cutting and improving production efficiency. The molten raw material is precisely shaped by the forming orifice plate 107, and the cut material is screened by the sieve plate 108 to ensure the consistency of the size and shape of the spherical particles. The air pump 206 delivers gas to the air collar 204 through the air pipe 207. When the cutting blade 201 is working, the gas is ejected through the connecting groove 218 to preliminarily cool the material just cut, effectively avoiding adhesion and improving the quality of the finished product. When the hollow rotating rod 200 is stationary, the gas in the air ring 204 drives the blades 214 to rotate through the side tube 213, and then pushes the unscreened material through the connecting piece 216, the rotating ring 215 and the push plate 217, thereby achieving full utilization and efficient processing of the material. After cooling and pushing the material, the gas used in the process can be partially recycled, reducing energy consumption and environmental pollution. When the spherical particles fall into the receiving box 400, they are buffered by the buffer rubber pad 401, and at the same time, the piston spring rod 407 is squeezed to push the gas in the air cylinder 405 through the connecting pipe 406 to the rolling plate 403, and finally ejected through the air outlet 404, which performs the final cooling and dust removal on the spherical particles, which is both energy-saving and environmentally friendly.
