Description

Environmentally friendly domestic waste loading method and domestic waste loading system Technical Field

[0001] The present invention relates to the technical field of domestic waste transportation, and in particular to a domestic waste transfer and loading method and system. Background Art

[0002] At present, after domestic waste is collected through various methods and enters the transfer site (this stage of domestic waste collection and transportation is often called front-end domestic waste collection), the domestic waste must be compressed and then transported to the treatment site.

[0003] The main purpose of compressing domestic waste is to remove moisture from it. If the wastewater is not compressed, it will seep into the soil and groundwater after landfill, causing soil and groundwater pollution and seriously harming the ecological environment. Although technological advances have gradually replaced landfill as the primary method of domestic waste treatment, the traditional method of compressing domestic waste before transporting it to large domestic waste dumps has not changed.

[0004] The existing technical solution of compressing domestic waste before transporting it to the treatment site has the following technical problems:

[0005] 1) The compression mechanism is susceptible to damage. Domestic waste can easily cause jamming, corrosion, and other damage to the moving parts of the compression mechanism. Domestic waste is complex and can contain stones, tiles, and even steel bars. These hard objects can easily jam and damage the compression mechanism.

[0006] Second, the compressed wastewater is leachate, which, if discharged without treatment, can seriously pollute the environment. Treating leachate requires dedicated sites and is costly. Furthermore, since leachate disposal only addresses a small portion of waste pollution (incineration is the only solution), dedicated leachate disposal currently appears ineffective from both a social and economic perspective. Dedicated leachate disposal significantly increases the cost of domestic waste disposal. With the widespread adoption of incineration, dedicated leachate disposal is no longer available in many areas. Consequently, leachate generated by compressed, transit-through transport continues to pollute the environment. Furthermore, the significant environmental pollution caused by compressed wastewater also complicates site selection for waste transfer stations.

[0007] 3) Compression processing prolongs the domestic waste treatment process. The compression process itself will increase the cost of domestic waste treatment and seriously reduce the efficiency of transferring domestic waste from transfer stations to incineration sites.

[0008] Fourth, the "hook-arm" garbage transport system used with compression has high "dead weight" and low payload. The hook-arm loading system of a hook-arm transporter is a laborious lever, and the chassis must add the "dead weight" of the hook arm. To accommodate this "labor," the waste container used with the hook-arm transporter must be strengthened, further increasing its "dead weight." This added dead weight significantly reduces the payload.

[0009] 5) Another existing method of vertical garbage loading involves a front-end garbage truck dumping garbage into a loading hopper, which then guides the garbage into the truck's cargo box (the cargo box of such trucks requires a dedicated mechanism to erect it). There's no seal between the hopper and the opening of the cargo box. During loading, the falling garbage causes a large amount of gas in the cargo box and hopper to rise. This rising odor diffuses into the surrounding air from two locations: through the gap between the lower end of the hopper and the cargo box opening, and from the upper end of the hopper. Although the existing vertical garbage loading transfer station has a negative pressure suction device for sucking out odor, the suction port of the negative pressure suction device is arranged on the outside of the lower end of the funnel or on the outside of the upper end of the funnel, but the suction is performed on the outside of the funnel. Since the odor rushes out of the funnel at a high speed under the impact of garbage, and the outside of the funnel, especially the outside of the upper end of the funnel, is a large open space, the negative pressure suction port is at a long distance from the gas odor source. Therefore, it is difficult to absorb the odor escaping from the funnel if the suction port is arranged on the outside of the funnel port. Therefore, the suction effect of the odor is poor, and a large amount of odor leakage will cause serious air pollution, which is also the main cause of air pollution around the existing garbage transfer station. Technical issues

[0010] In view of this, the purpose of the present invention is to provide an environmentally friendly domestic waste loading method and domestic waste loading system to solve the technical problems that the existing domestic waste needs to be compressed before loading, and sewage and odor pollute the environment during the loading process, as well as the technical problem that the economic benefits of using hook-arm garbage trucks to transport domestic waste are poor, and to solve the technical problem of odor pollution in the existing vertical garbage loading method.

[0026] Furthermore, the first lifting mechanism is a chain lifting mechanism, and the second lifting mechanism is an electric cylinder.

[0027] Furthermore, the domestic waste loading system also includes an exhaust device for extracting gas from the garbage loading funnel and a deodorization device for deodorizing the gas extracted by the exhaust device, and the deodorization device includes at least one of a combustion deodorization device, a chemical deodorization device or a biological deodorization device.

[0028] Furthermore, a rectangular annular groove is provided at the upper end of the sealing spacer, and the exhaust device includes an air duct and a fan connected to the air duct, and the inlet of the air duct is connected to the rectangular annular groove; air vents are provided around the upper end of the rectangular annular cavity of the garbage loading funnel, and the lower end of the material guide port of the garbage loading funnel is located on the inner side of the upper end of the rectangular annular cavity; when the upper end edge of the material guide port is in contact with the upper end edge of the rectangular annular groove, the air vent is connected to the rectangular annular groove.

[0029] Furthermore, the deodorizing device is a combustion deodorizing device, which includes a combustion furnace, a vertical combustion chamber and a cooling device, and the vertical combustion chamber is connected to the gas outlet end of the combustion furnace; the air duct includes a gas drainage pipe connecting the rectangular ring groove and the air inlet of the combustion furnace and an exhaust pipe connected to the exhaust port of the vertical combustion chamber, and the fan is arranged at the outlet end of the exhaust pipe; the cooling device includes a cooling water tank arranged outside the vertical combustion chamber and the exhaust pipe and a cooling water pipe wrapped around the outside of the vertical combustion chamber.

[0030] Furthermore, it also includes a blowing device arranged above the garbage loading funnel to supply air from top to bottom, and the air supply volume of the blowing device from top to bottom is less than the negative pressure suction volume of the vents arranged around the upper end of the rectangular ring cavity of the garbage loading funnel. Beneficial effects

[0031] 1. The environmentally friendly domestic waste loading method and domestic waste loading system of the present invention allow the front-end domestic waste collection vehicle to directly pour the collected domestic waste into the garbage loading funnel, and the domestic waste is directly loaded into the cargo box of the garbage transport vehicle through the garbage loading funnel. During the process of changing vehicles and transporting domestic waste, the waste does not fall to the ground at all, thus preventing the problem of odor and sewage caused by the falling waste from spreading to the surrounding area and polluting the environment.

[0032] 2. In the environmentally friendly domestic waste loading method and domestic waste loading system of the present invention, during the domestic waste loading process, the lower end of the garbage loading funnel and the cargo box opening of the garbage transport truck form a rectangular annular sealing structure, which can effectively prevent odor and sewage from leaking out and polluting the environment during the garbage loading process.

[0033] 3. In the environmentally friendly domestic waste loading method and domestic waste loading system of the present invention, after loading is completed, the garbage loading funnel is driven by the first lifting mechanism to rise and reset, and the sealing cover is driven by the second lifting structure to seal on the lower end of the sealing sleeve. This can prevent the residual odor and sewage in the garbage loading funnel from leaking out, and can further improve the environmental protection effect of garbage loading.

[0034] 4. The environmentally friendly domestic waste loading method and domestic waste loading system of the present invention can allow the sewage accumulated in the front domestic waste truck to flow naturally from high to low into the garbage box of the garbage transport truck during the garbage loading process. Compared with the horizontal loading method, the accumulated sewage will not scatter when dumping the garbage, and the loading is more environmentally friendly.

[0035] 5. The environmentally friendly domestic waste loading method and domestic waste loading system of the present invention, during the garbage loading process, the garbage loading funnel and the cargo box together form a closed container. When the odor in the closed container reaches the vents around the upper end of the rectangular ring cavity of the garbage loading funnel during the rising process, the odor can be immediately extracted by the exhaust device and sent to the deodorizing device for deodorization. This deodorizing method extracts the odor before the odor rushes out of the garbage loading funnel. Since the garbage loading funnel is a relatively small and closed space, and the distance between the vents and the odor in the garbage loading funnel is small, the suction effect of the odor can be greatly improved, and the odor is prevented from escaping into the garbage. Outside the garbage loading truck funnel (once the odor escapes into the large space outside the garbage loading funnel, it will be difficult to complete the extraction of the odor, which is also the main reason for the serious odor pollution in existing garbage treatment plants). This is significantly different from the existing vertical garbage loading method in which negative pressure suction ports are set on the outside of both ends of the loading funnel and the odor is extracted after it rushes out of the funnel. Compared with the existing technology, this invention can greatly reduce the odor in the garbage loading workshop, significantly improve the air quality around the garbage loading funnel, better ensure the health of the workers in the workshop, and better avoid the problem of odor leaking from the workshop to the surrounding atmosphere to cause air pollution.

[0036] 6. The environmentally friendly domestic waste loading method and domestic waste loading system of the present invention do not require compression of domestic waste during its turnover and transportation, which can greatly improve the efficiency of domestic waste transportation. At the same time, it also eliminates the problems of compression equipment being easily damaged, compressed sewage polluting the environment, and compressed domestic waste increasing corporate costs.

[0037] 7. The existing method of compressing domestic waste before loading causes serious environmental pollution due to the discharged wastewater, making it difficult to locate transfer stations for compressed waste, which in turn makes it difficult to transport domestic waste in urban areas. The environmentally friendly domestic waste loading method and system of the present invention can eliminate the waste compression step, making it easier to locate transfer stations, thereby facilitating the timely collection and transportation of domestic waste in urban areas.

[0038] 8. The environmentally friendly domestic waste loading method and domestic waste loading system of the present invention uses a garbage transport truck that does not have the hook arm structure used to hook the cargo box of a hook-arm garbage truck, which greatly reduces the truck's weight and can increase the garbage carrying capacity of a single truck. Therefore, it has higher economic benefits than the existing transportation using hook-arm garbage trucks.

[0039] 9. In the environmentally friendly domestic waste loading method and domestic waste loading system of the present invention, after loading is completed, the garbage loading funnel rises and resets under the drive of the first lifting mechanism. At this time, the outside of the air vents around the upper end of the rectangular annular cavity of the garbage loading funnel and the rectangular annular groove provided at the upper end of the sealing spacer are exposed in an easily cleaned position, making it easy to clean the air vents and the rectangular annular grooves. Although air suction and deodorization in the garbage loading funnel have significant advantages, the air vents will often be blocked by garbage under the huge suction force, and must be cleaned frequently. However, in conventional designs, the deodorization ventilation ducts are difficult to clean during the closed loading process between the garbage loading funnel and the cargo box. Easy cleaning allows the significant environmental advantages of air suction and deodorization in the garbage loading funnel to be better realized, which is also a significant advantage of the present technical solution.

[0046] The present invention will be further described below with reference to the accompanying drawings and examples.

[0047] Example 1: The environmentally friendly method for loading domestic waste into a truck in this embodiment includes the following steps:

[0048] 1) The garbage truck drives to the bottom of the sealing sleeve 1 outside the garbage loading hopper 2.

[0049] 2) When the cargo box of the garbage truck is in a horizontal parking state, remove the cargo box cover of the garbage truck and the sealing cover at the lower end of the sealing spacer.

[0050] 3) Lower the garbage loading funnel to the cargo box opening of the garbage truck, so that the lower end of the garbage loading funnel and the surrounding of the cargo box opening form a rectangular ring-shaped sealing structure.

[0051] 4) The front-end domestic waste collection truck drives to the garbage transfer workshop and pours the garbage into the garbage loading funnel. The domestic waste falls from the garbage loading funnel into the cargo box of the garbage transport truck.

[0052] 5) Level the garbage in the cargo box in the garbage loading hopper.

[0053] 6) Lift the garbage loading hopper back to its original position.

[0054] 7) Move the cargo box cover and sealing cover back, then put the cargo box cover back on the cargo box and cover the sealing cover on the lower end of the sealing sleeve.

[0055] As an improvement to the above embodiment, the environmentally friendly method for loading domestic waste also includes extracting gas from the waste loading hopper for deodorization.

[0056] Example 2: A domestic waste loading system that implements the above-mentioned environmentally friendly domestic waste loading method includes a fixed sealing sleeve 1, a garbage loading funnel 2 arranged in the sealing sleeve for introducing garbage into the cargo box of the garbage transport truck, and a first lifting mechanism 3 for driving the garbage loading funnel to rise and fall.

[0057] In this embodiment, the first lifting mechanism 3 is a chain-type lifting mechanism, specifically comprising a sprocket, a chain connected to the sprocket, a drive shaft connected to the sprocket, and a motor connected to the drive shaft. The chain is connected to the garbage loading hopper 2. Of course, in different embodiments, the first lifting mechanism 3 can also adopt other forms, such as an electric hoist, an electric cylinder, a hydraulic cylinder, a pneumatic cylinder, a gear and rack combination, etc., to drive the garbage loading hopper 2 up and down.

[0058] The domestic waste loading system also includes a traveling vehicle positioned below the sealing spacer. The traveling vehicle's mobile frame 4 is equipped with a second lifting mechanism 5, which is equipped with a sealing cover 6 for sealing the lower end of the sealing spacer. The traveling vehicle's mobile frame is also equipped with a lid retrieval device for retrieving and placing the cargo cover of the garbage truck. In this embodiment, the second lifting mechanism 5 is an electric cylinder. Of course, in different embodiments, the second lifting mechanism 5 can also be a hydraulic cylinder, a pneumatic cylinder, or other forms. In this embodiment, the lid retrieval device includes a hook 7 for connecting to the cargo cover and a hook drive mechanism for driving the hook for lateral and vertical movement. In this embodiment, the hook drive mechanism includes a horizontal guide rail 8 fixed to the mobile frame of the crane, a transverse slide 9 slidably engaged with the horizontal guide rail, a rack 10 mounted on the mobile frame of the crane and parallel to the horizontal guide rail, a motor 11 mounted on the transverse slide, a gear connected to the motor's rotating shaft and meshing with the rack (the gear is not shown in the figure due to being obscured), a vertical guide rail 12 mounted on the transverse slide, a lift slide 13 slidably engaged with the vertical guide rail, and an electric cylinder 14 mounted on the transverse slide. The push rod of the electric cylinder is arranged parallel to the vertical guide rail and connected to the lift slide. The hook is mounted on the lift slide. Of course, the box cover pick-and-place device can also adopt other forms in different embodiments.

[0059] In the specific implementation, the sealing sleeve 1 and the garbage loading funnel 2 are arranged on the floor layer of the garbage transfer workshop. The front-end garbage transport truck pours domestic garbage into the garbage loading funnel 2 in the garbage transfer workshop, and the garbage loading funnel 2 guides the domestic garbage into the garbage transport truck under the floor layer.

[0060] The process of taking and placing the cargo box cover 15 and the sealing cover 6 of the garbage transport truck is as follows:

[0061] Lid removal process: When the garbage truck drives under the sealing cover 6, the lid retrieval device starts working: first, the motor 11 drives the gear to roll on the rack 10, thereby driving the transverse slide 9 to move toward the cargo box cover 15. When the hook 7 is located below the cargo box cover 15, the motor 11 stops working. Then, the electric cylinder 14 drives the lifting slide 13 to move upward, thereby driving the hook 7 to move upward. When the hook 7 contacts the cargo box cover 15, the cargo box cover 15 begins to be lifted upward. When the cargo box cover 15 is lifted into place, the electric cylinder 14 stops working. At the same time, the second lifting mechanism 5 drives the sealing cover 6 downward, thereby separating the sealing cover 6 from the sealing spacer 1. The traveling frame 4 then moves horizontally along the driving track, thereby moving the cargo box cover 15 and the sealing cover 6 away from the top of the cargo box.

[0062] After the cargo box cover and sealing cover are removed, the first lifting mechanism drives the garbage loading hopper 2 down to the cargo box, and the lower end of the garbage loading hopper forms a rectangular ring-shaped sealing structure with the surrounding area of ​​the cargo box opening. Then, the front garbage truck pours domestic garbage into the garbage loading hopper 2, and then the domestic garbage enters the cargo box from the garbage loading hopper 2. After loading is completed, the first lifting mechanism drives the garbage loading hopper 2 to move up and reset.

[0063] Cover placement process: When domestic garbage is loaded into the cargo box of the garbage transport truck and the garbage loading funnel 2 moves up and reset, the mobile frame 4 of the vehicle moves horizontally along the driving track, thereby moving the cargo box cover 15 and the sealing cover 6 horizontally to the top of the cargo box; then the second lifting mechanism 5 drives the sealing cover 6 to move upward, thereby covering the sealing cover 6 on the lower end portion of the sealing spacer 1; at the same time, the electric cylinder 14 works to drive the lifting slide 13 to move downward, thereby putting the cargo box cover 15 back on the cargo box, and then the motor 11 works to make the hook 7 move horizontally back to its position on both sides.

[0064] As an improvement to the above embodiment, the garbage loading hopper 2 comprises a rectangular annular cavity 201, a material guide port 202 disposed at the upper end of the rectangular annular cavity, and a cargo box side sealing structure disposed at the lower portion of the rectangular annular cavity. In a specific embodiment, the garbage loading hopper 2 may further include a frame 206 disposed outside the rectangular annular cavity 201 and the material guide port 202 to enhance the structural strength of the garbage loading hopper 2. The cargo box side sealing structure comprises a sleeve 203 that slides and seals against the outer wall of the rectangular annular cavity, a sealing plate 204 disposed at the lower end of the sleeve, and a limit structure 205 for limiting the downward movement of the sleeve. In this embodiment, the limiting structure 205 is a stopper block positioned at the lower end of the rectangular annular cavity 201. The sliding sleeve 203 is provided with a vertical slot that mates with the stopper block. When the upper end of the vertical slot contacts the stopper block as the sliding sleeve 203 slides downward, the sliding sleeve 203 is prevented from sliding further downward. Of course, in different embodiments, the limiting structure can also be implemented in other forms. For example, the limiting structure can also consist of a vertical rod connected to the sealing plate 204 and a stopper plate connected to the rectangular annular cavity 201 that slides up and down with the vertical rod. The upper end of the vertical rod has a stopper flange. When the stopper flange on the upper end of the vertical rod contacts the stopper plate as the sliding sleeve 203 slides downward, the sliding sleeve 203 is prevented from sliding further downward. Alternatively, the limiting structure can be a sling connecting the sliding sleeve 203 to the rectangular annular cavity 201. A rectangular window is provided in the middle of the sealing plate 204 to prevent the garbage from falling. During loading, the sealing plate 204 presses against the edge of the cargo box's opening, preventing the garbage and odor from leaking out. As more and more garbage is piled up in the cargo box of the garbage truck, the tires of the garbage truck will be deformed, and the position of the cargo box opening will gradually move downward a certain distance. At this time, because the material guide port 202 is placed on the sealing spacer 1, the material guide port 202 and the rectangular annular cavity 201 will no longer be pressed down, and the sliding sleeve 203 and the sealing plate 204 will move downward with the deformation of the tire under the action of their own gravity, thereby ensuring that the sealing plate 204 will always not separate from the edge of the cargo box opening during the garbage loading process, thereby ensuring the reliability of the seal.

[0065] As an improvement to the above-mentioned embodiment, the top of the sealing cover 6 is provided with a water collection chamber 61, and the bottom of the sealing cover is provided with a drain pipe 16 connected to the water collection chamber, which is equipped with an electric valve 17. When the sealing cover 6 is placed on the lower end of the sealing spacer 1, the sewage remaining in the garbage loading funnel 2 flows down into the water collection chamber 61 and is stored. When the driving movable frame drives the sealing cover 6 to move horizontally away from the top of the cargo box, the electric valve 17 is opened, and the sewage collected in the water collection chamber 61 is discharged into the cargo box (in the specific embodiment, the outlet end of the drain pipe 16 is located at the front of the cargo box cover, so the cargo box cover does not affect the sewage from entering the cargo box). This improvement can further prevent the problem of sewage leakage and environmental pollution during the loading of domestic garbage.

[0066] As an improvement to the above embodiment, the domestic waste loading system also includes an exhaust device for extracting the gas in the garbage loading funnel and a deodorization device for deodorizing the gas extracted by the exhaust device, and the deodorization device includes at least one of a combustion deodorization device, a chemical deodorization device or a biological deodorization device.

[0067] In this embodiment, a rectangular annular groove 18 is provided at the upper end of the sealing spacer 1. The exhaust device includes an air duct 19 and a fan 20 connected to the air duct. The air duct's inlet communicates with the rectangular annular groove. A vent 206 is provided around the upper end of the rectangular annular cavity of the garbage loading hopper. The lower end of the material guide port of the garbage loading hopper is located inside the upper end of the rectangular annular cavity. When the upper edge of the material guide port contacts and cooperates with the upper edge of the rectangular annular groove, the vent communicates with the rectangular annular groove. In this embodiment, the lower end of the material guide port is located inside the upper end of the rectangular annular cavity, ensuring that garbage does not enter the vent 206. During the process of dumping garbage into the garbage loading hopper, the fan of the exhaust device works, and the gas in the garbage loading hopper first enters the rectangular annular groove 18 through the air vent 206, then enters the air duct from the rectangular annular groove 18, and enters the deodorizing device through the air duct, thereby extracting and deodorizing the odor generated during the garbage dumping process, which can greatly reduce the odor in the garbage loading workshop and improve the air quality of the loading operation environment.

[0068] As an improvement to the above embodiment, the domestic waste loading system also includes a blowing device 26 arranged above the garbage loading funnel to blow air from top to bottom. The air supply of the blowing device from top to bottom is less than the negative pressure suction volume of the vents arranged around the upper end of the rectangular annular cavity of the garbage loading funnel. In this embodiment, the blowing device is a fan. The front-end domestic waste collection truck drives into the garbage transfer workshop and dumps the garbage into the garbage loading funnel. When the garbage is dumped, solid and liquid garbage is poured out from the car box, and air flow will enter the car box, and the car box opening for dumping garbage becomes a negative pressure suction port; at the same time, the vents 206 arranged around the upper end of the rectangular annular cavity of the garbage loading funnel also suck air under negative pressure; two negative pressure air flows are generated at very close locations; the two negative pressure air flows will interfere with each other. The fan blowing air from top to bottom eliminates this interference. Furthermore, the collection port at the top of the garbage loading hopper is trumpet-shaped. When the fan blows air downward from top to bottom, the trumpet-shaped collection port draws air from the trumpet's edge toward the center. During garbage dumping, odors are also drawn from the trumpet's edge toward the center, driven by the downward airflow generated by the fan. During the garbage dumping process, the positive pressure airflow generated by the exhaust fan, the negative pressure airflow generated by the vents 206 located around the upper end of the rectangular annular cavity of the garbage loading hopper, and the weight of the odor combine to maximize the flow of odor into the deodorizing device, thus preventing odors from escaping the garbage loading hopper.

[0069] In this embodiment, the deodorizing device is a combustion deodorizing device, comprising a combustion furnace 21, a vertical combustion chamber 22, and a cooling device. The vertical combustion chamber is connected to the gas outlet of the combustion furnace. The air duct 19 comprises a gas drainage pipe 191 connecting the rectangular annular groove with the combustion furnace's air inlet and an exhaust pipe 192 connected to the exhaust outlet of the vertical combustion chamber. The fan is located at the outlet of the exhaust pipe. The cooling device comprises a cooling water tank 23 located outside the vertical combustion chamber and the exhaust pipe, and a cooling water pipe 24 surrounding the vertical combustion chamber. Garbage odor enters the combustion furnace through the gas drainage pipe 191. The combustion furnace ignites to produce a high-temperature flame. Toxic and harmful substances in the garbage odor are carbonized and decomposed within the combustion furnace and the vertical combustion chamber. In particular, within the vertical combustion chamber, the high temperature generated by the outer flame of the combustion furnace fully carbonizes and decomposes the odor in the airflow, thereby achieving the purpose of disinfection and deodorization. Of course, in different embodiments, the gas extracted by the exhaust device can also be sent to a chemical deodorizing device or a biological deodorizing device for deodorization.

[0070] The cooling device provided in the combustion and deodorization device in this embodiment can reduce the temperature of the outer wall of the vertical combustion chamber, thereby extending the service life of the vertical combustion chamber; by cooling the exhaust pipe, the temperature of the exhaust gas can be reduced, which is beneficial to protecting the exhaust fan.

[0071] In a specific implementation, a number of small air intake holes 25 can be provided at the outlet of the exhaust pipe 192. These holes can introduce cool air, further reducing the exhaust temperature and thus better protecting the exhaust fan. Furthermore, in a specific implementation, a diameter-enhanced section can be provided on the vertical combustion chamber. When the garbage odor contains a high concentration of flammable gases, deflagration may occur after the garbage odor is introduced into the combustion furnace. This section can effectively buffer the shock wave generated by the deflagration, providing an explosion-proof effect.

[0072] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not limiting. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the purpose and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
