Description

Technical Field

[0001] The invention relates to the technical field of ditch desilting, in particular to a ditch desilting device. Background Art

[0002] Among municipal road infrastructure, drainage ditches, as a key component of the urban drainage system, are crucial for treating and removing sewage and rainwater from roads. Due to various reasons, they often become clogged and lose their drainage function, severely impacting road conditions. Consequently, drainage ditch desilting and maintenance are frequently required.

[0003] The prior art also proposes a solution for ditch dredging. For example, a Chinese patent application with the publication number CN221480915U discloses a ditch dredging device, which includes a mounting plate, a limit plate fixedly connected to the surface of the mounting plate, a scraper screwed to the bottom of the limit plate via a connecting plate, a square array of equidistant through-holes on the surface of the scraper, arc-shaped plates welded to both sides of the scraper, and a ring plate fixedly connected to one side of the limit plate, the surface of the ring plate having a rotation groove. The ditch dredging device, through the arrangement of the connecting plate, scraper, and cutting assembly, connects the servo motor to an external power supply, and its transmission rod drives the rotating rod to rotate, and the cutting blade rotates accordingly. The cutting blade cuts underwater foreign matter, and the scraper scrapes the silt on the bottom of the water, thereby achieving the purpose of facilitating personnel to clean the ditch.

[0004] Although the above technical solution uses a cutting blade to cut underwater foreign objects, there are still other problems in its actual use. For example, there is a lot of silt in the ditch. After the silt is dug out, the excavated silt is generally piled on the roadside or taken away by a truck for subsequent processing. However, since the silt is not dehydrated, it will take up a large space, which is not conducive to subsequent processing.

[0005] Therefore, it is necessary to provide a ditch desilting device to solve the above problems.

[0006] It should be noted that the above information disclosed in this Background section is only for understanding the background of the present inventive concept and therefore it may contain information that does not constitute the prior art. Summary of the Invention

[0008] Furthermore, a rotating frame is rotatably provided on the upper end surface of the dredging vehicle, the connecting bracket is connected to the side wall of the rotating frame through a plurality of cross bars, and the deflection bracket is connected to the side wall of the rotating frame through a plurality of cross bars; when working, the deflection bracket and the connecting bracket are driven to rotate by the rotating frame, so that the depth of the dredging frame in the ditch can be conveniently adjusted, thereby improving the treatment effect of the silt in the ditch.

[0009] Furthermore, a rotating vertical shaft is provided inside the processing frame, and the end of the rotating vertical shaft is connected to the output end of the external motor. A plurality of groups of crushing rods are fixedly installed on the outer circumference of the rotating vertical shaft. The plurality of groups of crushing rods are circumferentially arranged on the outer circumference of the rotating vertical shaft. The shape of the crushing rods is conical. A suction pipe is provided at the bottom of the processing frame, and the suction pipe is used to suck the crushed sludge.

[0010] Furthermore, a frame is fixedly installed at the bottom of the dredging vehicle, and two sets of transmission shafts are rotatably arranged inside the frame. The outer peripheral surfaces of the two sets of transmission shafts are jointly provided with a transmission belt, and the transmission direction of the transmission belt is designed to correspond to the outlet end of the suction pipe. The ends of the two sets of transmission shafts are connected by belts, and the end of one of the transmission shafts is connected to the output end of the external motor. A centrifugal dehydration chamber is installed at the lower edge of the dredging vehicle, and the opening of the centrifugal dehydration chamber is designed along the transmission direction of the transmission belt; when working, the crushed sludge will be sucked into the surface of the conveyor belt through the suction pipe, and the rotation of the transmission shaft is controlled by an external controller, and the transmission shaft drives the conveyor belt to operate, and the conveyor belt transports relatively uniform sludge to the inside of the centrifugal dehydration chamber. After the dehydration process inside the centrifugal dehydration chamber, the uniform sludge can be dehydrated, thereby facilitating the production of mud cakes and subsequent use. The conveyor belt is designed to facilitate the transportation of crushed sludge.

[0011] Furthermore, a support plate is installed under the dredging vehicle, and multiple groups of separation rods are installed on the lower end surface of the support plate. The bottom end of each group of separation rods is in contact with the end surface of the conveyor belt. The shape of the bottom end of the separation rod is conical, and multiple groups of separation rods are designed to be equidistant above the conveyor belt.

[0012] Furthermore, a fixed frame is installed at the bottom of the dredging vehicle, and a rotating horizontal axis is rotatably arranged inside the fixed frame. A plurality of groups of connecting rods are fixedly installed on the outer peripheral surface of the rotating horizontal axis, and each group of connecting rods and separation rods are designed to be spaced apart. A scraper rod is installed at the bottom end of the connecting rod, and the scraper rod is hook-shaped; during operation, when the conveyor belt is transmitting the silt and some plastic bags are blocked on one side of the separation rod, at the same time, the rotating horizontal axis is controlled to rotate, and the rotating horizontal axis drives the connecting rod and scraper rod on its outer side to rotate clockwise. Since the connecting rod, scraper rod and separation rod are designed to be spaced apart, the hook-shaped scraper rod will hook some of the blocked plastic bags during the clockwise rotation, which is convenient for the subsequent automatic collection of the hooked plastic bags.

[0013] Furthermore, a collection frame is installed under the dredging vehicle. When the rotating horizontal axis drives the scraper rod to rotate, the end face of the scraper rod will contact the side wall of the collection frame. The scraper rod is rotatably arranged at the bottom of the connecting rod, and a torsion spring is provided at the rotation connection position between the scraper rod and the connecting rod.

[0014] Furthermore, a limiting frame is provided on the side of the dredging vehicle, the support plate is slidably provided inside the limiting frame, and a dispersion unit is provided inside the limiting frame, and the dispersion unit is used to disperse the silt on one side of the separation rod; during operation, as the separation rod gradually separates the silt, if there is still some silt that is not completely crushed, the side force of the separation rod will increase, and since the support plate is slidably provided inside the limiting frame, the dispersion unit inside the limiting frame will be triggered, so that the dispersion unit will further disperse the silt on one side of the separation rod, thereby facilitating the treatment of the silt.

[0015] Furthermore, the dispersion unit includes a sliding rod slidably arranged inside the limit frame, the end of the sliding rod is connected to the side wall of the support plate, a limiting arc block is installed on the outer side of the sliding rod, and a limiting groove is provided inside the limit frame. The shapes of the limiting arc block and the limiting groove are adapted to each other, and contact one is installed at the end of the sliding rod, and contact two is installed on the inner wall of the limit frame. Two sets of crushing disks are provided under the dredging vehicle, and the crushing disks are controlled by an external hydraulic system. A conical rod is provided on the surface of the crushing disk.

[0016] Furthermore, the interior of the limit frame is provided with a groove adapted to the slide rod, and a limit spring is installed inside the groove, and one end of the limit spring is connected to the side wall of the slide rod; during operation, when the crushing disk crushes the sludge, the rotating horizontal axis will stop running under the control of the external controller. When the crushing disk completes the crushing of the sludge, the external controller will first control the crushing disk to return to its initial position, and then control the rotating horizontal axis to operate again, so that the further crushed sludge is transported along the separation rods, thereby improving the sludge treatment efficiency.

[0017] The beneficial effect of the present invention is that a ditch silt clearing device provided by the present invention drives the connecting rod and the scraper rod to rotate clockwise by rotating the horizontal axis, that is, when the scraper rod rotates to one side of the collection frame, since the scraper rod rotation is set at the bottom of the connecting rod, when the scraper rod contacts the collection frame, under the limit of the collection frame, the scraper rod will rotate to a certain extent, and then as the scraper rod continues to move, the plastic bag on the surface of the scraper rod will slowly fall into the inside of the collection frame.

[0018] The transmission shaft is controlled to rotate by an external controller, and the transmission shaft drives the conveyor belt to operate. The conveyor belt transports relatively uniform sludge to the inside of the centrifugal dehydration chamber. After the dehydration process inside the centrifugal dehydration chamber, the uniform sludge can be dehydrated, thereby facilitating the formation of mud cakes for subsequent use. The conveyor belt is designed to facilitate the transportation of crushed sludge.

[0019] By increasing the force on the side of the separation rod, the force on the separation rod and the support plate on its upper side increases, so the support plate will drive the slide bar to slide inside the limit frame. When the force on the side of the separation rod is greater than the clamping force of the limit arc block and the limit groove, the slide bar will drive contact one to contact contact two, so that the external circuit is connected, and the external controller will control the external hydraulic system to drive the crushing disk to move, that is, the crushing disk will move to the side of the accumulated silt. After that, the tapered rod on the surface of the crushing disk can further crush some of the silt that has not passed through the separation rod when it comes into contact with the silt, thereby facilitating the transmission of the silt.

[0034] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments of the present invention can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0035] In order to enable those skilled in the art to better understand the solutions of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the embodiments described 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 should fall within the scope of protection of the present invention.

[0036] like Figures 1 to 10As shown, the present invention provides a ditch desilting device, including a desilting vehicle 1. Four sets of movable wheels 2 are installed around the lower part of the desilting vehicle 1. A fixing seat 3 is installed on the upper end surface of the desilting vehicle 1. A deflection bracket 301 is rotatably provided on the outer side of the fixing seat 3. A connecting bracket 4 is rotatably provided in front of the deflection bracket 301. A dredging frame 5 is rotatably provided on the lower end surface of the connecting bracket 4. The dredging frame 5 is used to dredge the silt in the ditch. A processing frame 6 is installed on the side wall of the desilting vehicle 1. The processing frame 6 is used to crush the dredged silt. A centrifugal dehydration chamber 14 is installed on the lower edge of the desilting vehicle 1.

[0037] During operation, the mobile wheels 2 are controlled by an external controller to drive the entire silt removal vehicle 1 to a suitable position in the ditch, and then the deflection bracket 301, the connecting bracket 4 and the silt excavation frame 5 are controlled by an external hydraulic drive system to move closer to the inside of the ditch, so that the silt excavation frame 5 excavates the silt inside the ditch, and then the excavated silt will enter the processing frame 6, so that the processing frame 6 will perform subsequent crushing processing on the silt. In this way, the silt in the ditch is continuously processed, which is convenient for the subsequent use of the ditch. Moreover, under the action of the connecting bracket 4 and the deflection bracket 301, the flexibility of the silt excavation frame 5 can be improved, and ditches of various depths can be further silted. After that, the crushed silt will be transferred to the centrifugal dehydration chamber 14 for dehydration processing, which is convenient for the subsequent continued processing of the silt, such as making mud cakes for use.

[0038] It should be noted that when the broken small pieces of sludge enter the centrifugal dehydration chamber 14, centrifugal dehydration of the sludge can be facilitated.

[0039] It should be noted that the deflection bracket 301, the connecting bracket 4 and the dredging frame 5 in the embodiment of the present invention are all controlled by an external hydraulic drive system, and the control method and the digging method are similar to the principles of the excavator in the prior art, and no unnecessary details are given in the embodiment of the present invention.

[0040] The upper end surface of the dredging vehicle 1 is rotatably provided with a rotating frame 7, the connecting bracket 4 is connected to the side wall of the rotating frame 7 through multiple cross bars, and the deflection bracket 301 is connected to the side wall of the rotating frame 7 through multiple cross bars; when working, the deflection bracket 301 and the connecting bracket 4 are driven to rotate by the rotating frame 7, which can facilitate the adjustment of the depth of the dredging frame 5 in the ditch, thereby improving the treatment effect of the silt in the ditch.

[0041] The internal rotation of the processing frame 6 is provided with a rotating vertical shaft 8, the end of the rotating vertical shaft 8 is connected to the output end of the external motor, and the outer circumference of the rotating vertical shaft 8 is fixedly installed with multiple groups of breaking rods 9, which are circumferentially arranged on the outer circumference of the rotating vertical shaft 8. The breaking rods 9 are conical in shape, and a suction pipe 10 is provided at the bottom of the processing frame 6. The suction pipe 10 is used to suck the crushed silt; when working, the silt excavated by the dredging frame 5 will be poured into the interior of the processing frame 6 under its own rotation, and then the rotating vertical shaft 8 is driven to rotate by the external controller, and the rotating vertical shaft 8 drives the breaking rod 9 on its outer side to rotate, and the breaking rod 9 will crush the silt blocks with larger block diameters, and then the crushed silt is extracted to the subsequent processing steps through the suction pipe 10. The crushed silt has uniform particle size and strong fluidity, which is convenient for subsequent centrifugal dehydration of the silt and is also beneficial for separation from impurities such as plastic and other substances in the silt.

[0042] A frame 11 is fixedly installed at the bottom of the dredging vehicle 1, and two sets of transmission shafts 12 are rotatably set inside the frame 11. The outer circumferential surfaces of the two sets of transmission shafts 12 are jointly provided with a conveyor belt 13. The transmission direction of the conveyor belt 13 is designed to correspond to the outlet end of the suction pipe 10. The ends of the two sets of transmission shafts 12 are connected by belts, and the end of one of the transmission shafts 12 is connected to the output end of the external motor. The opening of the centrifugal dehydration chamber 14 is designed along the transmission direction of the conveyor belt 13; when working, the crushed sludge will be sucked into the surface of the conveyor belt 13 through the suction pipe 10, and the transmission shaft 12 is controlled to rotate by an external controller. The transmission shaft 12 drives the conveyor belt 13 to operate, and the conveyor belt 13 transports relatively uniform sludge to the inside of the centrifugal dehydration chamber 14. After the dehydration process inside the centrifugal dehydration chamber 14, the uniform sludge can be dehydrated, thereby facilitating the production of mud cakes and subsequent use. The conveyor belt 13 is designed to facilitate the transportation of crushed sludge.

[0043] A support plate 15 is installed below the silt removal vehicle 1, and a plurality of separation rods 151 are installed on the lower end surface of the support plate 15. The bottom end of each group of separation rods 151 contacts the end surface of the conveyor belt 13. The bottom end of the separation rod 151 is conical. The plurality of separation rods 151 are designed to be equidistant above the conveyor belt 13. When working, refer to the attached Figure 5 As shown, the bottom end of each set of separation rods 151 contacts the end surface of the conveyor belt 13. When the conveyor belt 13 transports the crushed sludge, the sludge passes through the separation rods 151. Under the limit of the separation rods 151, on the one hand, it can not only block the plastic bags in the sludge to prevent the plastic bags from entering the subsequent centrifugal dehydration chamber 14, but also further separate the sludge, making the sludge more uniform during the transmission process, that is, it can organize the sludge during the transmission process, which is convenient for subsequent centrifugal dehydration.

[0044] It should be noted that the diameter of the blocked plastic bag is greater than the distance between two adjacent separation rods 151 .

[0045] A fixing frame 16 is installed at the bottom of the silt clearing vehicle 1, and a rotating horizontal shaft 17 is rotatably set inside the fixing frame 16. A plurality of connecting rods 18 are fixedly installed on the outer circumference of the rotating horizontal shaft 17. Each connecting rod 18 and the separating rod 151 are designed to be spaced apart. A scraper rod 19 is installed at the bottom end of the connecting rod 18, and the scraper rod 19 is hook-shaped. During operation, when the conveyor belt 13 is transmitting silt and some plastic bags are blocked on one side of the separating rod 151, at the same time, the rotating horizontal shaft 17 is controlled to rotate, and the rotating horizontal shaft 17 drives the connecting rod 18 and the scraper rod 19 on its outer side to rotate clockwise. Since the connecting rod 18, the scraper rod 19 and the separating rod 151 are designed to be spaced apart, the hook-shaped scraper rod 19 will hook some of the blocked plastic bags during the clockwise rotation, which is convenient for the subsequent automatic collection of the hooked plastic bags.

[0046] A collecting frame 20 is installed at the bottom of the silt removal vehicle 1. When the rotating horizontal shaft 17 drives the scraper rod 19 to rotate, the end face of the scraper rod 19 will contact the side wall of the collecting frame 20. The scraper rod 19 is rotatably arranged at the bottom of the connecting rod 18. A torsion spring is provided at the rotation connection position of the scraper rod 19 and the connecting rod 18. When working, refer to the attached Figure 5 、 Figure 6 and Figure 7 As shown in FIG. 1 , when the rotating horizontal shaft 17 drives the connecting rod 18 and the scraping rod 19 to rotate clockwise, that is, when the scraping rod 19 rotates to the side of the collection frame 20, since the scraping rod 19 is rotatably arranged at the bottom of the connecting rod 18, when the scraping rod 19 contacts the collection frame 20, under the limit of the collection frame 20, the scraping rod 19 will rotate to a certain extent and rotate to the position shown in FIG. Figure 8 As shown, as the scraper rod 19 continues to move, the plastic bags on the surface of the scraper rod 19 will slowly fall into the collection frame 20.

[0047] A limiting frame 21 is provided on the side of the silt clearing vehicle 1, and the support plate 15 is slidably provided inside the limiting frame 21. A dispersion unit is provided inside the limiting frame 21, and the dispersion unit is used to disperse the silt on one side of the separation rod 151; during operation, as the separation rod 151 gradually separates the silt, if there is still some silt that is not completely crushed, the side force of the separation rod 151 will increase, and since the support plate 15 is slidably provided inside the limiting frame 21, the dispersion unit inside the limiting frame 21 will be triggered, so that the dispersion unit will further disperse the silt on one side of the separation rod 151, thereby facilitating the treatment of the silt.

[0048] The dispersion unit includes a slide rod 22 slidably arranged inside the limit frame 21, the end of the slide rod 22 is connected to the side wall of the support plate 15, a limit arc block 23 is installed on the outside of the slide rod 22, a limit slot 24 is arranged inside the limit frame 21, the shape of the limit arc block 23 and the limit slot 24 are adapted, a contact 1 25 is installed at the end of the slide rod 22, a contact 2 26 is installed on the inner wall of the limit frame 21, two sets of crushing discs 27 are arranged under the dredging vehicle 1, the crushing discs 27 are controlled by an external hydraulic system, and a tapered rod is provided on the surface of the crushing disc 27; when working, in the initial state, the limit arc block 23 is located inside the limit slot 24, and the contact 1 25 and contact 2 26 are not in contact; as the force on the side of the separation rod 151 increases, the force on the separation rod 151 and the support plate 15 on its upper side increases, so the support plate 15 will drive the slide bar 22 to slide inside the limit frame 21. When the force on the side of the separation rod 151 is greater than the clamping force of the limit arc block 23 and the limit groove 24, the slide bar 22 will drive contact 1 25 to contact contact 2 26, so that the external circuit is connected, and the external controller will control the external hydraulic system to drive the crushing disk 27 to move, that is, the crushing disk 27 will move toward the side of the accumulated silt. After that, the conical rod on the surface of the crushing disk 27 can further crush some of the silt that has not passed through the separation rod 151 when it comes into contact with the silt, thereby facilitating the transmission of the silt.

[0049] It should be noted that, refer to the attached Figure 8 As shown, the crushing disk 27 is controlled by an external hydraulic cylinder, and the hydraulic cylinder is installed under the silt clearing vehicle 1. The telescopic end of the hydraulic cylinder contacts the end face of the crushing disk 27. It should also be noted that the surface of the crushing disk 27 is provided with multiple groups of conical rods.

[0050] The interior of the limit frame 21 is provided with a groove adapted to the slide bar 22, and a limit spring 28 is installed in the groove, one end of the limit spring 28 is connected to the side wall of the slide bar 22; when working, when the crushing disc 27 crushes the silt, the rotating horizontal shaft 17 will stop running under the control of the external controller. When the crushing disc 27 completes the crushing of the silt, the external controller will first control the crushing disc 27 to return to the initial position, and then control the rotating horizontal shaft 17 to run again, so that the further crushed silt is transported along the separation rods 151, thereby improving the silt treatment efficiency;

[0051] It should be noted that when the slide bar 22 drives contact 1 25 to contact contact 2 26, the slide bar 22 will simultaneously squeeze the limit spring 28 on its side. After the sludge on one side of the separation rod 151 is processed, the elastic force of the limit spring 28 is restored, and the slide bar 22 will drive the support plate 15 and the separation rod 151 to return to their initial positions, thereby facilitating the subsequent continued transportation of the sludge. It should be noted that the elastic force recovery of the limit spring 28 is sufficient to drive the support plate 15 and the separation rod 151 to return to their initial positions.

[0052] Working principle: The mobile wheel 2 is controlled by an external controller to drive the entire silt removal vehicle 1 to move to a suitable position in the ditch, and then the deflection bracket 301, the connecting bracket 4 and the silt excavation frame 5 are controlled by an external hydraulic drive system to move closer to the inside of the ditch, so that the silt excavation frame 5 can excavate the silt inside the ditch, and then the excavated silt will enter the processing frame 6, so that the processing frame 6 can subsequently crush the silt. In this way, the silt in the ditch is continuously processed, which is convenient for the subsequent use of the ditch. Moreover, under the action of the connecting bracket 4 and the deflection bracket 301, the silt removal efficiency can be improved. The flexibility of the dredging frame 5 further enables dredging of ditches of various depths; the silt excavated by the dredging frame 5 is poured into the interior of the processing frame 6 under its own rotation, and then the rotating vertical shaft 8 is driven to rotate by an external controller, and the rotating vertical shaft 8 drives the crushing rod 9 on the outside thereof to rotate, and the crushing rod 9 will crush the silt blocks with larger block diameters, and then the crushed silt is extracted to the subsequent processing step through the suction pipe 10. The crushed silt has a uniform particle size and strong fluidity, which is convenient for subsequent centrifugal dehydration of the silt and is also conducive to separation from impurities such as plastic and other substances in the silt;

[0053] Refer to the attached Figure 5 As shown, the bottom end of each set of separation rods 151 contacts the end surface of the conveyor belt 13. When the conveyor belt 13 transports the crushed sludge, the sludge passes through the separation rods 151. Under the limit of the separation rods 151, on the one hand, it can not only block the plastic bags in the sludge to prevent the plastic bags from entering the subsequent centrifugal dehydration chamber 14, but also further separate the sludge, making the sludge more uniform during the transmission process, that is, it can organize the sludge during the transmission process, which is convenient for subsequent centrifugal dehydration.

[0054] When the conveyor belt 13 is transporting the sludge and some plastic bags are blocked on one side of the separation rod 151, at the same time, the horizontal shaft 17 is controlled to rotate, and the horizontal shaft 17 drives the connecting rod 18 and the scraping rod 19 on the outside thereof to rotate clockwise. Since the connecting rod 18, the scraping rod 19 and the separation rod 151 are designed to be spaced apart, the hook-shaped scraping rod 19 will hook some of the blocked plastic bags during the clockwise rotation process, which is convenient for the subsequent automatic collection of the hooked plastic bags. Figure 5 、 Figure 6 and Figure 7 As shown in FIG. 1 , when the rotating horizontal shaft 17 drives the connecting rod 18 and the scraping rod 19 to rotate clockwise, that is, when the scraping rod 19 rotates to the side of the collection frame 20, since the scraping rod 19 is rotatably arranged at the bottom of the connecting rod 18, when the scraping rod 19 contacts the collection frame 20, under the limit of the collection frame 20, the scraping rod 19 will rotate to a certain extent and rotate to the position shown in FIG. Figure 8 As shown, as the scraper rod 19 continues to move, the plastic bags on the surface of the scraper rod 19 will slowly fall into the collection frame 20;

[0055] In the initial state, the limit arc block 23 is located inside the limit groove 24, and the contact 1 25 and the contact 2 26 are not in contact; as the force on the side of the separation rod 151 increases, the force on the separation rod 151 and the support plate 15 on its upper side increases, so the support plate 15 will drive the slide bar 22 to slide inside the limit frame 21. When the force on the side of the separation rod 151 is greater than the clamping force of the limit arc block 23 and the limit groove 24, the slide bar 22 will drive the contact 1 25 to contact with the contact 2 26, so that the external circuit is connected, and the external controller will control the external hydraulic system to drive the crushing disk 27 to move, that is, the crushing disk 27 It will move toward the side of the accumulated silt, and then the tapered rods on the surface of the crushing disk 27 can further crush some of the silt that has not passed through the separation rods 151 when they come into contact with the silt, thereby facilitating the transmission of the silt; when the crushing disk 27 is crushing the silt, the rotating horizontal shaft 17 will stop running under the control of the external controller. When the crushing disk 27 completes the crushing of the silt, the external controller will first control the crushing disk 27 to return to its initial position, and then control the rotating horizontal shaft 17 to operate again, so that the further crushed silt is transported along between the separation rods 151, thereby improving the silt treatment efficiency.

[0056] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that various modifications and variations of the present invention are possible. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention are intended to be within the scope of protection of the present invention.
