Description

Technical Field

[0001] This invention relates to the field of wastewater treatment technology, specifically to a device for the harmless treatment of wastewater from mineral processing reagent preparation. Background Technology

[0002] In mineral processing, a large amount of flotation reagents are added to the water to change the hydrophobicity of minerals and facilitate mineral stratification. The wastewater generated after mineral processing contains a large amount of metal ions. The residual metal ions in the wastewater will combine with the flotation reagents to form precipitates. These precipitates contain a large amount of heavy metal ions and need to be treated to render them harmless in order to prevent pollution to the environment when directly discharged.

[0003] Chinese patent CN113461229B discloses a wastewater treatment device for mineral processing reagents, belonging to the technical field of wastewater treatment equipment for mineral processing reagents. It includes a wastewater purification tank with a drain outlet extending through the lower right surface. A drain pipe is fixedly connected to the top of the tank, and a sludge inlet box is fixedly connected to the top of the inner surface. A rotating rod is located on the inner left surface of the inlet box, and a conveyor belt is movably connected to the outer right surface of the rotating rod. The patent utilizes two rectangular rods that move upward within two sliding grooves. An L-shaped baffle moves upward, deforming the elastic rod. When the water level increases to a certain height, a floating block also moves upward simultaneously, opening the drain outlet slightly and allowing purified water to drain out. After a certain amount of water is discharged, the floating block moves downward, closing the drain outlet. This helps maintain the water level in the wastewater purification tank and prevents a decrease in purification efficiency due to excessive wastewater.

[0004] However, the current wastewater harmless treatment device has the following problems: when treating wastewater, it is not convenient to follow the liquid level of the wastewater to treat the scum. If the scum is not removed in time according to the changes in the liquid level, it is easy for the scum to accumulate in the wastewater, affecting the wastewater treatment effect and even causing secondary pollution. Therefore, we propose a wastewater harmless treatment device for mineral processing reagent preparation. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this invention provides a device for the harmless treatment of wastewater from mineral processing reagent preparation, which solves the problems mentioned in the background section.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a device for the harmless treatment of wastewater from mineral processing reagent preparation, comprising a main body, a treatment chamber on the front side of the main body, and a collection chamber on the rear side of the main body. A dispensing device is installed within the treatment chamber, comprising an inlet pipe fixed to the top of the main body. A semi-circular shell is fixed to the bottom of the inlet pipe, and an arc shell is fixed to the side of the semi-circular shell near the collection chamber, forming a C-shaped channel between the semi-circular shell and the arc shell. A hollow tube is rotatably installed inside the semi-circular shell, driven by a motor. Several nozzles are uniformly fixed to the outer circumference of the hollow tube. A dispensing assembly for supplying treatment agent to the hollow tube is located on the front side of the main body. An intercepting net is fixed to the bottom of the arc shell. A drain pipe is fixed below the outer wall of the main body, located between the intercepting net and the inner wall of the treatment chamber. The dispensing assembly includes a water treatment agent tank, which is fixed... At the front of the main body of the device, a pump is fixed to the outside of the water treatment agent tank. A connecting pipe is fixed to the outlet end of the pump. A connector is fixed to the end of the connecting pipe away from the pump and is fixed to the outer wall of the main body of the device. A hollow tube is rotatably installed outside the connector, and the inside of the hollow tube is connected to the inside of the connector. The pump draws water treatment agent from the water treatment agent tank and transmits it to the connector through the connecting pipe. The connector delivers the water treatment agent to the hollow tube. The hollow tube delivers the water treatment agent and sprays it into the semi-circular shell through the spray nozzle, thereby mixing the water treatment agent with the wastewater entering the semi-circular shell. This ensures that the water treatment agent and wastewater have more uniform contact and promotes the reaction between the agent and the pollutants in the wastewater. During this process, the motor drives the hollow tube to rotate the spray nozzle. At the same time, the C-shaped channel structure between the semi-circular shell and the arc shell further increases the contact area between the wastewater and the water treatment agent. It is worth noting that most of the flocculent material generated by the reaction between the wastewater and the water treatment agent will be intercepted by the interception net, and a small amount of flocculent material will pass through the interception net.

[0007] According to the above technical solution, the dispensing device further includes a swing plate, two spiral frames, and two L-shaped columns. The swing plate is hinged to the lower outer wall of the semi-circular shell. The two spiral frames are respectively fixed to the top two sides of the swing plate. One end of each of the two L-shaped columns is slidably installed on the inner wall of the semi-circular shell, and the other end of each L-shaped column is slidably installed inside the two spiral frames. Several semi-circular blocks are evenly and equidistantly fixed on both outer walls of the hollow tube. The horizontal support of the L-shaped columns is located at the movement of the semi-circular blocks of the hollow tube. On the trajectory, as the hollow tube rotates, it drives the semicircular block on it to rotate. The semicircular block of the hollow tube pushes the L-shaped column to move upward along the inner wall of the semicircular shell. The L-shaped column slides along the inside of the ring frame, and the L-shaped column drives the swing plate to swing upward through the ring frame. When the semicircular block of the hollow tube stops pushing the L-shaped column, the swing plate returns to its original position and swings downward. This process repeats, and the swing plate periodically guides the water flow to impact the C-shaped channel formed between the semicircular shell and the arc shell, thereby changing the flow path of the mixed wastewater and water treatment agent.

[0008] According to the above technical solution, a scum removal device is provided on the rear side of the interior of the treatment chamber. The scum removal device includes a pulley, a reciprocating screw, a pump, and a float. The pulley is fixed to the outside of the hollow tube. The reciprocating screw is rotatably installed on the rear side of the interior of the treatment chamber. The pulley is fixed to the side of the reciprocating screw, and the pulley is connected to the pulley via a belt drive. A movable plate is threaded onto the outside of the reciprocating screw. The float is located inside the treatment chamber. A collection box is fixed to the top of the float, and a crossbar is fixed to the top of the collection box. Side boxes are fixed on both sides of the collection box near the hollow tube. The pump is fixed to the top of the collection chamber by a bracket. An L-shaped folded pipe is fixed to the inlet end of the pump. The end of the L-shaped folded pipe away from the pump is fixed to the top of the crossbar. A U-shaped sliding plate is slidably installed inside the collection box. One end of the U-shaped sliding plate slides... The U-shaped slide plate is mounted on the outer wall of the moving plate. A scraper is fixed at the other end of the U-shaped slide plate and is located between the two side boxes. As the wastewater level inside the treatment chamber rises, the float will float on the surface of the wastewater due to buoyancy. The float will also cause the collection box and the side boxes to float on the surface of the wastewater. At the same time, the collection box will cause the U-shaped slide plate to slide upward along the outside of the moving plate. When the hollow tube rotates, it will drive the first pulley to rotate. Under the belt drive, the first pulley will drive the second pulley to rotate through the belt. The second pulley will drive the reciprocating screw to rotate. The reciprocating screw will drive the moving plate to move back and forth. The moving plate will drive the U-shaped slide plate to move back and forth along the inside of the collection box. When the U-shaped slide plate moves, it will drive the scraper to move back and forth between the two side boxes. The scraper will scrape the scum on the surface of the wastewater into the side boxes. The side boxes will guide the scum to the collection box. Then, the second pump will be started. The second pump will pump the scum in the collection box into the collection chamber for collection through the L-shaped folded pipe.

[0009] According to the above technical solution, the scum removal device further includes a friction wheel, a friction plate, and a rotating rod. The rotating rod is rotatably mounted on the bottom of the scraper. Several agitating blades are evenly fixed on the outer circumference of the rotating rod. The friction wheel is fixed on the side of the rotating rod near the collection box. The friction plate is fixed on the outer wall of the collection box. The outer surface of the friction wheel is rough, and the top surface of the friction plate is rough. The outer surface of the friction wheel is in contact with the top surface of the friction plate. During the reciprocating movement of the scraper, the scraper drives the friction wheel to move along with it through the rotating rod. Under the action of friction between the friction wheel and the friction plate, the friction plate drives the friction wheel to rotate. The friction wheel drives the rotating rod to rotate, and the rotating rod drives the agitating blades to stir the wastewater below the scum.

[0010] According to the above technical solution, the scum removal device further includes a U-shaped lifting plate, an abutment rod, and two elastic telescopic rods. The fixed ends of the two elastic telescopic rods are respectively fixed to the bottom sides of the inner wall of the collection box. The U-shaped lifting plate is fixed to the top of the telescopic ends of the elastic telescopic rods. The two support plates of the U-shaped lifting plate are respectively located inside the two side boxes, and the two long support plates of the U-shaped lifting plate are inclined. The abutment rod is fixed to the top of the U-shaped sliding plate, and the top of the abutment rod is semi-circular. Several semi-circular shapes are fixed to the bottom of the U-shaped lifting plate. The U-shaped lifting plate has a semi-circular protrusion located on the semi-circular motion trajectory of the abutment rod. During the reciprocating movement of the U-shaped sliding plate, the abutment rod is driven to move. The semi-circular shape of the abutment rod pushes the semi-circular protrusion of the U-shaped lifting plate, causing the U-shaped lifting plate to move upward. The U-shaped lifting plate also causes the extension end of the elastic telescopic rod to stretch. When the semi-circular shape of the abutment rod no longer pushes the semi-circular protrusion of the U-shaped lifting plate, under the elastic force of the elastic telescopic rod, the elastic telescopic rod causes the U-shaped lifting plate to reset and move downward. This process repeats, causing the U-shaped lifting plate to bounce up and down.

[0011] This invention provides a device for the harmless treatment of wastewater from mineral processing reagent preparation. It has the following beneficial effects:

[0012] (1) This invention, through the setting of the dispensing device, allows the water treatment agent to mix with the wastewater entering the semi-circular shell, thereby ensuring more uniform contact between the water treatment agent and the wastewater, promoting the reaction between the agent and the pollutants in the wastewater. Furthermore, the hollow tube drives the spray nozzle to rotate, ensuring that the water treatment agent is evenly sprayed into the wastewater, ensuring a more uniform distribution of the agent in the wastewater. This helps to improve the contact rate and reaction efficiency between the agent and the pollutants in the wastewater. Simultaneously, the C-shaped channel structure between the semi-circular shell and the arc shell further increases the contact area between the wastewater and the water treatment agent. When the wastewater flows through the C-shaped channel, the flow velocity and direction change due to the tortuous shape of the C-shaped channel, enhancing the reaction efficiency. The mixing effect of wastewater and water treatment agent helps the agent to fully react throughout the wastewater flow, improving the efficiency of pollutant removal. Simultaneously, the hollow pipe, L-shaped column, semi-circular shell, and U-shaped frame work together to drive the oscillating plate to periodically guide the water flow to impact the C-shaped channel formed between the semi-circular shell and the arc shell. This alters the flow path of the mixed wastewater and water treatment agent, generating a vortex effect. The water flow repeatedly impacts and rotates within the C-shaped channel. This rotating flow further increases the contact time and area between the water flow and the water treatment agent, promoting the uniform distribution of the agent and enhancing the contact and reaction effect between the agent and pollutants in the wastewater, thereby improving the treatment effect.

[0013] (2) By setting up a scum removal device, the scraper moves back and forth between the two side boxes. The scraper scrapes the scum on the surface of the wastewater into the side boxes. The side boxes guide the scum to the collection box. The pump 2 pumps the scum in the collection box into the collection chamber through the L-shaped folded pipe for collection. By treating the scum on the surface of the wastewater, the accumulation of pollutants on the surface of the wastewater is reduced, and the wastewater is kept clean.

[0014] (3) The present invention uses a scraper, a rotating rod, a friction wheel, and a friction plate to drive the agitator to stir the wastewater below the scum. The agitator can effectively break the adhesion between the scum and the wastewater by stirring the wastewater below the scum, making it easier for the scum to be scraped into the side box by the scraper. At the same time, the U-shaped sliding plate, the contact rod, the U-shaped lifting plate, and the elastic telescopic rod work together to drive the U-shaped lifting plate to bounce up and down, thereby promoting the efficiency of the scum in the side box flowing into the collection box.

[0023] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0024] Please see Figure 1 - Figure 7This invention provides a technical solution: a device for harmlessly treating wastewater from mineral processing reagent preparation, comprising a main body 1, a processing chamber 11 formed on the front side of the main body 1, and a collection chamber 2 formed on the rear side of the main body 1. A dispensing device 3 is installed within the processing chamber 11, comprising an inlet pipe 31 fixed to the top of the main body 1, a semi-circular shell 34 fixed to the bottom of the inlet pipe 31, and an arc shell 35 fixed to the side of the semi-circular shell 34 near the collection chamber 2, forming a C-shaped channel between the semi-circular shell 34 and the arc shell 35. A hollow tube 36 is rotatably mounted inside the device 34 and is driven by a motor. Several spray nozzles 37 are evenly fixed around the outer circumference of the hollow tube 36. An injection assembly 33 for supplying treatment agent to the hollow tube 36 is located on the front side of the device body 1. A screen 32 is fixed to the bottom of the arc shell 35. A drain pipe is fixed below the outer wall of the device body 1, and the drain pipe is located between the screen 32 and the inner wall of the treatment chamber 11. The injection assembly 33 includes a water treatment agent tank 331, which is fixed to the front side of the device body 1. A pump 332 is fixed externally to the main body 1. A connecting pipe 333 is fixed to the outlet end of the pump 332. A connector 334 is fixed to the end of the connecting pipe 333 away from the pump 332, and the connector 334 is fixed to the outer wall of the main body 1. A hollow pipe 36 is rotatably installed outside the connector 334, and the interior of the hollow pipe 36 is connected to the interior of the connector 334. Through the above structure, the water treatment agent is mixed with the wastewater entering the semi-circular shell 34, thereby ensuring more uniform contact between the water treatment agent and the wastewater and promoting the reaction between the agent and the pollutants in the wastewater. During this process, the motor drives the hollow tube 36 to rotate the spray nozzle 37, thereby ensuring that the water treatment agent can be evenly sprayed into the wastewater, ensuring a more uniform distribution of the water treatment agent in the wastewater. This helps to improve the contact rate and reaction efficiency between the agent and the pollutants in the wastewater. At the same time, the C-shaped channel structure between the semi-circular shell 34 and the arc shell 35 further increases the contact area between the wastewater and the water treatment agent. When the wastewater flows through the C-shaped channel, the flow rate and flow direction of the wastewater change due to the tortuous shape of the C-shaped channel, which enhances the mixing effect between the wastewater and the water treatment agent.

[0025] The dispensing device 3 also includes a swing plate 38, two spiral frames 39, and two L-shaped columns 310. The swing plate 38 is hinged to the lower outer wall of the semi-circular shell 34. The two spiral frames 39 are respectively fixed to the top two sides of the swing plate 38. One end of each of the two L-shaped columns 310 is slidably installed on the inner wall of the semi-circular shell 34, and the other end of each of the two L-shaped columns 310 is slidably installed inside the two spiral frames 39. Several semi-circular blocks are evenly and equidistantly fixed on both outer walls of the hollow tube 36. The horizontal support of the L-shaped column 310 is located at the semi-circle of the hollow tube 36. On the block's motion trajectory, the aforementioned structure allows the oscillating plate 38 to periodically guide the water flow to impact the C-shaped channel formed between the semi-circular shell 34 and the arc shell 35. This alters the flow path of the mixed wastewater and water treatment agent, generating a vortex effect. The water flow repeatedly impacts and rotates within the C-shaped channel. This rotating flow further increases the contact time and area between the water flow and the water treatment agent, promoting the uniform distribution of the water treatment agent and enhancing the contact and reaction effect between the water treatment agent and pollutants in the wastewater, thereby improving the treatment effect.

[0026] A scum removal device 4 is installed on the rear side of the interior of the treatment chamber 11. The scum removal device 4 includes a pulley 41, a reciprocating screw 43, a pump 45, and a float 410. The pulley 41 is fixed to the outside of the hollow tube 36. The reciprocating screw 43 is rotatably installed on the rear side of the interior of the treatment chamber 11. A pulley 42 is fixed to the side of the reciprocating screw 43, and the pulley 42 is connected to the pulley 41 via a belt drive. A moving plate 44 is threaded to the outside of the reciprocating screw 43. The float 410 is located inside the treatment chamber 11. It should be noted that as the wastewater level inside the treatment chamber 11 rises, the float 410 will be buoyed by the wastewater inside the treatment chamber 11 and will float on the surface of the wastewater. A collection box 49 is fixed to the top of the float 410, and a crossbar 48 is fixed to the top of the collection box 49. Both sides of the collection box 49 near the hollow tube 36 are fixed. A side box 411 is fixed, and a second pump 45 is fixed to the top of the collection chamber 2 by a bracket. An L-shaped folded pipe 46 is fixed to the water inlet end of the second pump 45. The end of the L-shaped folded pipe 46 away from the second pump 45 is fixed to the top of the cross frame 48. A U-shaped slide plate 47 is slidably installed inside the collection box 49. One end of the U-shaped slide plate 47 is slidably installed on the outer wall of the moving plate 44, and the other end of the U-shaped slide plate 47 is fixed with a scraper 412, which is located between the two side boxes 411. With the above structure, the scraper 412 scrapes the scum on the surface of the wastewater into the side box 411. The side box 411 guides the scum to the collection box 49, and the second pump 45 draws the scum in the collection box 49 into the collection chamber 2 for collection through the L-shaped folded pipe 46. By treating the scum on the surface of the wastewater, the accumulation of pollutants on the surface of the wastewater is reduced, and the wastewater is kept clean.

[0027] The scum removal device 4 also includes a friction wheel 413, a friction plate 414, and a rotating rod 415. The rotating rod 415 is rotatably mounted on the bottom of the scraper 412. Several agitating blades 416 are evenly fixed on the outer circumference of the rotating rod 415. The friction wheel 413 is fixed on the side of the rotating rod 415 near the collection box 49. The friction plate 414 is fixed on the outer wall of the collection box 49. The outer surface of the friction wheel 413 is rough, and the top surface of the friction plate 414 is rough. The outer surface of the friction wheel 413 is in contact with the top surface of the friction plate 414. Through the above structure, the rotating rod 415 drives the agitating blades 416 to stir the wastewater below the scum. By stirring the wastewater below the scum, the agitating blades 416 can effectively break the adhesion between the scum and the wastewater, making it easier for the scum to be scraped into the side box 411 by the scraper 412.

[0028] The scum removal device 4 also includes a U-shaped lifting plate 417, an abutment rod 419, and two elastic telescopic rods 418. The fixed ends of the two elastic telescopic rods 418 are respectively fixed to the bottom sides of the inner wall of the collection box 49. The U-shaped lifting plate 417 is fixed to the top of the telescopic ends of the elastic telescopic rods 418. The two support plates of the U-shaped lifting plate 417 are respectively located inside the two side boxes 411, and the two long support plates of the U-shaped lifting plate 417 are inclined. The inclined arrangement can guide the scum entering the side box 411 to flow into the collection box 49. The abutment rod 419 is fixed to the top of the U-shaped sliding plate 47. The top of the abutment rod 419 is semi-circular. Several semi-circular protrusions are fixed to the bottom of the U-shaped lifting plate 417. The semi-circular protrusions of the U-shaped lifting plate 417 are located on the semi-circular movement trajectory of the abutment rod 419. Through the above structure, the U-shaped lifting plate 417 bounces up and down, thereby promoting the efficiency of the scum in the side box 411 flowing into the collection box 49.

[0029] In use, the inlet pipe 31 is connected to the external wastewater pipe, which then introduces wastewater into the treatment chamber 11 through the inlet pipe 31. During this process, the wastewater passes through the semi-circular shell 34 and the arc shell 35. Simultaneously, the injection assembly 33 is activated, and the pump 332 draws water treatment agent from the water treatment agent tank 331 and transmits it through the connecting pipe 333 to the connector 334. The connector 334 then delivers the water treatment agent to the hollow pipe 36, which in turn delivers the water treatment agent through the spray nozzle 37 into the semi-circular shell 34. This ensures that the water treatment agent mixes with the wastewater entering the semi-circular shell 34, guaranteeing proper contact between the water treatment agent and the wastewater. The more uniform contact promotes the reaction between the agent and pollutants in the wastewater. During this process, the motor drives the hollow tube 36 to rotate the spray nozzle 37, ensuring the water treatment agent is evenly sprayed into the wastewater. This ensures a more uniform distribution of the water treatment agent, which helps improve the contact rate and reaction efficiency between the agent and pollutants in the wastewater. Simultaneously, the C-shaped channel structure between the semi-circular shell 34 and the arc-shaped shell 35 further increases the contact area between the wastewater and the water treatment agent. When the wastewater flows through the C-shaped channel, the tortuous shape of the channel changes the flow velocity and direction, enhancing the contact between the wastewater and the water treatment agent. The mixing effect of the agent helps the agent to fully react throughout the wastewater flow, improving the efficiency of pollutant removal. It is worth noting that most of the flocculent material generated by the reaction between wastewater and water treatment agent will be intercepted by the interception net 32, while a small amount of flocculent material will pass through the interception net 32. When the hollow tube 36 rotates, the hollow tube 36 will drive the semicircular block on it to rotate. The semicircular block of the hollow tube 36 will push the L-shaped column 310 to move upward along the inner wall of the semicircular shell 34. The L-shaped column 310 slides along the inside of the loop frame 39, and the L-shaped column 310 drives the swing plate 38 to swing upward through the loop frame 39. When the semicircular block of the hollow tube 36 does not push the L-shaped column rod 310, the swing plate 38 returns to its original position and swings downward. This cycle repeats, and the swing plate 38 periodically guides the water flow to impact the C-shaped channel formed between the semicircular shell 34 and the arc shell 35. This changes the flow path of the mixed wastewater and water treatment agent and generates a certain vortex effect, causing the water flow to repeatedly collide and rotate in the C-shaped channel. This rotating flow further increases the contact time and contact area between the water flow and the water treatment agent, promotes the uniform distribution of the water treatment agent, enhances the contact and reaction effect between the water treatment agent and the pollutants in the wastewater, and thus improves the treatment effect.

[0030] As the wastewater level inside the treatment chamber 11 rises, the float 410, under buoyancy, floats on the wastewater surface. The float 410 also causes the collection box 49 and side box 411 to float on the wastewater surface. Simultaneously, the collection box 49 causes the U-shaped sliding plate 47 to slide upwards along the outside of the moving plate 44. When the hollow tube 36 rotates, it drives pulley 41 to rotate. Under belt drive, pulley 41 drives pulley 42 to rotate via the belt. Pulley 42 drives the reciprocating screw 43 to rotate, which in turn drives the moving plate 44 to move back and forth. The moving plate 44 then drives the U-shaped sliding plate 47 to move upwards along the outside of the moving plate 44. The U-shaped sliding plate 47 moves back and forth inside the collection box 49. As the U-shaped sliding plate 47 moves, it drives the scraper 412 to move back and forth between the two side boxes 411. The scraper 412 scrapes the scum on the surface of the wastewater into the side boxes 411, which then guide the scum into the collection box 49. Next, the second pump 45 is activated, and it pumps the scum from the collection box 49 into the collection chamber 2 through the L-shaped folded pipe 46 for collection. By treating the scum on the surface of the wastewater, the accumulation of pollutants on the wastewater surface is reduced, maintaining the cleanliness of the wastewater. During the reciprocating movement of the scraper 412... During the process, the scraper 412 drives the friction wheel 413 to move via the rotating rod 415. Under the action of friction between the friction wheel 413 and the friction plate 414, the friction plate 414 drives the friction wheel 413 to rotate. The friction wheel 413 drives the rotating rod 415 to rotate, and the rotating rod 415 drives the agitator 416 to stir the wastewater below the scum. By stirring the wastewater below the scum, the agitator 416 can effectively break the adhesion between the scum and the wastewater, making it easier for the scum to be scraped into the side box 411 by the scraper 412. At the same time, the reciprocating movement of the U-shaped sliding plate 47 will drive the agitator... When the contact rod 419 moves, the semicircular shape of the contact rod 419 pushes the semicircular protrusion of the U-shaped lifting plate 417, causing the U-shaped lifting plate 417 to move upward. The U-shaped lifting plate 417 also causes the telescopic end of the elastic telescopic rod 418 to stretch. When the semicircular shape of the contact rod 419 no longer pushes the semicircular protrusion of the U-shaped lifting plate 417, under the elastic force of the elastic telescopic rod 418, the elastic telescopic rod 418 causes the U-shaped lifting plate 417 to reset and move downward. This process is repeated, causing the U-shaped lifting plate 417 to bounce up and down, thereby promoting the efficiency of the scum in the side box 411 flowing into the collection box 49.

Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
