Description

Technical Field

[0001] The present invention relates to the technical field of domestic sewage pipe networks, and in particular to a sewage pipe network sediment control system and method based on flow velocity segmented lifting. Background Art

[0002] Currently, the problems of low efficiency in centralized collection of urban domestic sewage and low influent concentration in sewage treatment plants are still relatively common. As the main place for collecting and transporting domestic sewage of residents, the sewage pipe network is an important guarantee for low-carbon and efficient sewage treatment.

[0003] The sediment pollutants in domestic sewage pipes mainly come from organic pollutants, inorganic particles, microbial metabolites, etc. in domestic sewage. These substances gradually accumulate in the pipes and form sediments, posing a serious threat to the conveying capacity of the pipes, the treatment efficiency of subsequent sewage treatment plants, and the water environment. Currently, due to design defects or imperfect construction, operation and management, etc., pollutants will deposit due to too low flow velocity during sewage transfer. On the one hand, it is easy to block the pipes for a long time and affect normal use; on the other hand, low flow velocity will also cause the deposition and attenuation of pollutants, especially organic matter, resulting in the need for sewage treatment facilities to rely on adding external carbon sources to solve the problem of imbalance in the ratio of influent carbon, nitrogen and phosphorus.

[0004] Therefore, it is necessary to provide a sediment control system and method based on the improvement of pipe network flow velocity in combination with the actual construction and operation of the current pipe network facilities, so as to reduce the problem of pollutant deposition in the main silted pipe sections of community and municipal sewage pipe networks, which has important practical significance for solving the problem of pollutant deposition and low collection efficiency caused by too low flow velocity in the whole process of domestic sewage collection and transfer from the source to the end.

[0022] The present invention also provides a method for using the sewage pipe network sediment control system based on flow velocity segmented lifting, including:

[0023] a. Conduct an on-site survey of the current situation of the sewage pipe network to determine that the pipe sections with an average flow velocity lower than 0.1 m / s and a siltation depth exceeding 1 / 3 of the pipe diameter are target pipe sections. Install the sewage pipe network sediment control system in the sewage well at the end of the target pipe section, and connect the starting-end sewage well communicating with the starting end of the target pipe section to the external flushing pipe;

[0024] b. Transform the sewage well, deepen the bottom of the sewage well by 20 - 50 cm and make it into a conical structure, conduct anti-seepage treatment on the deepened part, set a 10 - 30 cm high intercepting weir at the sewage outlet of the sewage well, place the cutting-type lifting pump at the bottom of the sewage well, place the internal circulation pipe in the sewage well, and connect the external flushing pipe from the sewage well to the starting-end sewage well through shallow burial on the ground;

[0025] c. Sewage continuously enters the sewage well through other branch pipe inlets and the target pipe section. When the starting condition of the cutting-type lifting pump is reached, the cutting-type lifting pump extracts a part of the sewage and sprays it to the bottom of the sewage well for flushing, so that the sediment is separated from the bottom of the sewage well; at the same time, another part of the sewage extracted by the cutting-type lifting pump is transported to the starting-end sewage well through the external flushing pipe, and the sewage is pressurized and sprayed into the starting-end sewage well through a pressurizing nozzle. By increasing the water volume and high-pressure flushing, the flow velocity of the pipe section is increased, so that the sediment gradually separates from the pipe and enters the sewage well at the end of the target pipe section along with the sewage;

[0026] d. When the sediment control system is set in the sewage pipe network in a residential area, set the timing start time period: 9:00 - 11:00, 13:00 - 17:00, and continuously operate the sediment control system of the sewage pipe network;

[0027] e. When the deposition control system is installed in the municipal sewage network, set the start and stop liquid level values of the cutting type lift pump. In response to the liquid level rising to the start liquid level value, trigger the operation of the sewage network deposition control system. In response to the liquid level dropping to the stop liquid level value, the sewage network deposition control system stops operating.

[0028] The above technical solutions of the present invention have the following advantages compared with the prior art:

[0029] (1) The present invention uses a deposition reduction control system for the pipe network including facilities such as a cutting type lift pump, a filtration unit, an external flushing pipeline, and an internal circulation pipeline, so that the long-term accumulated sediment is separated from the bottom of the pipe network and timely collected and transferred into the sewage treatment facilities, which can effectively prevent the sewage from depositing in the manholes and pipelines, greatly reduce the deposition attenuation of organic pollutants during the collection and transfer process, and improve the centralized collection efficiency of sewage pollutants.

[0030] (2) The internal circulation system of the present invention can be combined with the timing automation control technology, which can realize remote monitoring and timing startup, facilitate the real-time management of the operation status of the community pipe network and the municipal pipe network, effectively reduce the accumulation of sediment and the frequency of pipeline blockage, reduce the maintenance frequency of the pipe network, and provide a new solution for the existing drainage system.

[0031] (3) The present invention has strong pertinence, practicability and operability, and is of great significance for supporting the improvement of the quality and efficiency of existing sewage, the improvement of water environment quality, and the low-carbon operation and maintenance of pipe networks.

[0032] Through the above technical solution of the present invention, in order to solve the problems of pollutant deposition and low collection efficiency caused by too low flow velocity in the whole process of domestic sewage collection and transfer from the source to the end, the present invention realizes the function of hydraulic circulation flushing by the combined use of a cutting type lift pump, an input pipeline, an internal circulation pipeline, an external flushing pipeline and a booster nozzle, in a way of segmentally increasing the flow velocity of the pipe network, so that part of the sewage in the sewage well at the end of the silted pipe section is diverted to the sewage well at the starting end, thus forming a circulating flushing flow state in the pipeline to solve the problems of pollutant deposition and low collection efficiency caused by too low flow velocity in the whole process of domestic sewage collection and transfer from the source to the end. Further, the present invention is also provided with a filtering unit. Through the setting of the filtering unit, when diverting sewage, it can avoid the phenomenon that solid impurities in the sewage enter the inside of the cutting type lift pump and cause blockage, thus ensuring the normal operation of the system. In order to solve the problem that a large amount of dirt may adhere to the inner wall of domestic sewage pipes with a long service life and a long transportation distance and is difficult to handle, an auxiliary cleaning unit is provided. Through the setting of the auxiliary cleaning unit, a cleaning agent can be automatically and quantitatively put into the circulating water during hydraulic circulation flushing. Thus, through the cooperation of the cleaning agent and hydraulic circulation flushing, the dirt in the domestic sewage pipes with a long service life and a long transportation distance can be effectively removed. At the same time, when the cleaning agent is put, no manual labor and additional power source are required, it is convenient to use, and the dosage can be adjusted, which is especially suitable for use in sewage pipe networks with a long service life and a long transportation distance.

[0069] Referring to Figure 1 , Figure 11 As shown, a sewage pipe network sediment control system based on flow velocity segmented lifting includes:

[0070] The cutting type lift pump 1 is arranged in the sewage well 9 and is used to pump the sewage in the sewage well 9 and simultaneously cut the solid impurities and fibrous substances in the sewage;

[0071] The filtering unit 3 is arranged at the input end of the cutting type lift pump 1 and is used to prevent the cutting type lift pump 1 from being blocked when pumping sewage and can automatically rotate during filtration;

[0072] The internal circulation pipeline 2 has one end connected to the output end of the cutting type lift pump 1, and the other end of the internal circulation pipeline 2 extends to the sewage well 9 to spray the sewage pumped by the cutting type lift pump 1 to the bottom of the sewage well 9 for scouring, so that the sediment is separated from the bottom of the sewage well and is in a suspended state;

[0073] The external scouring pipeline 4 has one end connected to the output end of the cutting type lift pump 1 and the other end extends to the sewage well 10 at the starting end of the silted pipe section and is used to transport the sewage in the sewage well 9 to the starting end sewage well 10;

[0074] The water wheel rotating unit 5 is arranged on the external scouring pipeline 4, and a pressurizing nozzle 6 is arranged at one end, and the pressurizing nozzle 6 is used to spray the sewage under pressure;

[0075] The auxiliary cleaning unit 8 is connected between the bottom end and the inner cavity of the external scouring pipeline 4 and is used to automatically add a cleaning agent when transporting sewage;

[0076] The adjusting linkage unit 7 is arranged between the auxiliary cleaning unit 8 and the water wheel rotating unit 5 and is used to transmit the rotational motion of the water wheel rotating unit 5 to the auxiliary cleaning unit 8 to control the amount of cleaning agent added by the auxiliary cleaning unit 8.

[0077] Through the above technical solution, by the combined use of the cutting type lift pump 1, the internal circulation pipeline 2, the external flushing pipeline 4 and the booster nozzle 6, in the way of segmentally increasing the flow velocity of the pipe network, the function of hydraulic circulation flushing is realized, and part of the sewage in the sewage well at the end of the silted pipe section is diverted to the starting sewage well, so as to form a circulating flushing flow pattern in the pipeline, so as to solve the problems of pollutant deposition and low collection efficiency caused by too low flow velocity in the whole process of domestic sewage collection and transfer from the source to the end. Further, through the setting of the filtering unit 3, when diverting sewage, the phenomenon that solid impurities in the sewage enter the inside of the cutting type lift pump 1 and cause blockage can be avoided, thus ensuring the normal operation of the system, in order to solve the problem that a large amount of dirt may adhere to the inner wall of the domestic sewage pipe with a long service life and a long transportation distance and is difficult to handle. By further setting the auxiliary cleaning unit 8, a cleaning agent can be automatically and quantitatively put into the circulating water during hydraulic circulation flushing. Thus, with the cooperation of the cleaning agent and hydraulic circulation flushing, the dirt in the domestic sewage pipe with a long service life and a long transportation distance can be effectively removed. At the same time, when the cleaning agent is put, no manual labor and redundant power sources are required, it is convenient to use, and the dosage can be adjusted, which is especially suitable for use in sewage pipe networks with a long service life and a long transportation distance.

[0078] It should be noted that by spraying the sewage pumped by the cutting type lift pump 1 to the bottom of the sewage well 9 through the internal circulation pipeline 2 for flushing, the pollutants such as sediment and solid particles at the bottom of the sewage well 9 can be effectively disturbed, so that the pollutants are separated from the bottom of the sewage well and in a suspended state, forming a circulating water flow, and preventing the pollutants from adhering and accumulating at the bottom of the well. By repeatedly flushing the bottom of the well, the retention of large particles or larger-sized solid debris at the inlet of the cutting type lift pump 1 can be reduced, and the filtering unit 3 can be prevented from being adhered or wound by impurities, thereby improving the continuous operation ability of the system.

[0079] Specifically, a regulating valve 11 is arranged on the internal circulation pipeline 2 for adjusting the water volume distribution between the internal circulation pipeline 2 and the external flushing pipeline 4; a check valve 17 is arranged on the external flushing pipeline 4. There is also provided:

[0080] A control unit 14, the control unit 14 includes a timing start module 15 electrically connected to the cutting type lift pump 1, and the timing start module 15 is used for controlling the start time of the cutting type lift pump 1;

[0081] A liquid level gauge 16, which is arranged in the sewage well 9 and electrically connected to the control unit 14. The liquid level gauge 16 is used for obtaining the liquid level data in the sewage well 9 in real time, and the control unit 14 can control the automatic start and stop of the cutting type lift pump 1 according to the liquid level data.

[0082] As a further technical solution, please refer to Figure 2As shown, an input pipe 13 is provided at the input end of the cutting type lift pump 1. The filtering unit 3 includes a suction nozzle 301, a rotating sleeve 302, filtering holes 303, a fixed round rod 304, and a spiral blade 305. The suction nozzle 301 is fixedly arranged at one end of the input pipe 2. A rotating sleeve 302 is rotatably sleeved on the arc-shaped wall of the suction nozzle 301. A number of filtering holes 303 are formed in the rotating sleeve 302. A fixed round rod 304 is fixedly connected to the center position of the inner wall of the rotating sleeve 302. A number of spiral blades 305 are fixedly connected to the arc-shaped wall of the fixed round rod 304. Through the arrangement of the filtering holes 303, the function of filtering solid impurities in the sewage can be achieved, avoiding blockage caused by solid impurities entering the interior of the cutting type lift pump 1 when sucking sewage. At the same time, due to the arrangement of the spiral blades 305, when water flows into the inner cavity of the rotating sleeve 302, the spiral blades 305 can be driven to rotate by the action of the water flow, thereby driving the fixed round rod 304 to rotate through the rotation of the spiral blades 305, and then driving the rotating sleeve 302 to rotate. Thus, through the rotation of the rotating sleeve 302, the function of self-rotation can be realized during the pumping process. Through rotation, the dirt attached to the filtering holes 303 can be shaken off, avoiding the problem of blockage caused by dirt attaching to the filtering holes 303. Therefore, compared with ordinary filtering devices, the filtering unit 3 is particularly suitable for use in domestic sewage pipes.

[0083] Specifically, please refer to Figure 3 As shown, the water wheel rotating unit 5 includes a fixed sleeve 501, a fixed bracket 502, a rotating rod 503, and a turbine 504. The fixed sleeve 501 is fixedly connected to one end of the external flushing pipe 4. A pressure increasing nozzle 6 is fixedly connected to one end of the fixed sleeve 501. Through the above arrangement, through the operation of the cutting type lift pump 1, the sewage in the sewage well 9 can be transported to the interior of the starting sewage well 10 through the external flushing pipe 4, thereby realizing the circulating flushing flow state in the pipeline, and improving the problem of pollutant deposition caused by too low flow velocity during the sewage transfer process of the domestic sewage pipe. At the same time, through the arrangement of the pressure increasing nozzle 6, pressurized water spraying can be carried out, making the spraying force stronger, which is beneficial to flushing off the dirt attached to the inner wall of the domestic sewage pipe and improving the cleaning effect.

[0084] Please refer to Figure 4As shown, a fixed support 502 is fixedly connected in the inner cavity of the fixed sleeve 501. A rotating rod 503 is rotatably connected at the central position of the fixed support 502. A turbine 504 is fixedly connected to the rotating rod 503. A bevel gear A505 is fixedly connected to one end of the rotating rod 503. A connecting rod 506 is rotatably connected in the inner cavity of the fixed sleeve 501. One end of the connecting rod 506 extends to the outer wall of the fixed sleeve 501. A bevel gear B507 is fixedly connected to the other end of the connecting rod 506. The bevel gear B507 meshes with the bevel gear A505. Through the above settings, when water flows through the fixed sleeve 501, the water flow can drive the turbine 504 to rotate. Thus, the rotation of the turbine 504 can drive the rotating rod 503 to rotate. Furthermore, the rotation of the rotating rod 503 can drive the bevel gear A505 to rotate. Therefore, the rotation of the bevel gear A505 can drive the bevel gear B507 to rotate, and then drive the connecting rod 506 to rotate. It can be understood that when the water flow circulates, the connecting rod 506 can be automatically driven to rotate.

[0085] As a further technical solution, please refer to Figure 5 As shown, the adjustment linkage unit 7 includes a support frame 701, a rotating rod 702, a gear set 706 and an adjustment part. The support frame 701 is fixedly arranged on the arc-shaped outer wall of the external flushing pipe 4. A rotating rod 702 is rotatably connected to the upper surface of the support frame 701. A gear set 706 is fixedly connected to the arc-shaped wall of the rotating rod 702. The gear set 706 is composed of several gears. A synchronous motion structure is arranged between the top end of the rotating rod 702 and the top end of the connecting rod 506. The synchronous motion structure is used to drive the synchronous motion between the connecting rod 506 and the rotating rod 702. Exemplarily, the synchronous motion structure includes a synchronous pulley A703, a synchronous belt 704 and a synchronous pulley B705. The synchronous pulley A703 is fixedly arranged at the upper end of the rotating rod 702. The synchronous pulley B705 is fixedly arranged at the upper end of the connecting rod 506. A synchronous belt 704 is sleeved between the synchronous pulley A703 and the synchronous pulley B705. Through this technical solution, when the connecting rod 506 rotates, it can drive the synchronous pulley B705 to rotate, thereby driving the synchronous belt 704 to move, and then driving the synchronous pulley A703 to rotate. Through the rotation of the synchronous pulley A703, the rotating rod 702 can be driven to rotate, so that the gear set 706 rotates.

[0086] As a specific technical solution, please refer to Figure 7 and Figure 8As shown, the adjusting part includes a fixing plate frame 707, a rectangular fixing shell 708, a rectangular adjusting rod 709, a rotating connecting rod 710 and a linkage gear 711. The fixing plate frame 707 is fixedly arranged at the auxiliary cleaning unit 8. A rectangular fixing shell 708 is fixedly connected to the fixing plate frame 707. A rectangular adjusting rod 709 is slidably connected in the inner cavity of the rectangular fixing shell 708. An inner cavity is arranged inside the rectangular adjusting rod 709. A fixing block 716 is fixedly connected in the inner cavity of the rectangular adjusting rod 709. An adjusting knob 718 is rotatably connected to the upper surface of the rectangular fixing shell 708. One end of a threaded rod 717 is fixedly connected to the bottom end of the adjusting knob 718. The other end of the threaded rod 717 extends into the inner cavity of the rectangular adjusting rod 709. The threaded rod 717 penetrates through the fixing block 716 and is in threaded cooperation with the fixing block 716. The bottom end of the rectangular adjusting rod 709 is rotatably connected to a rotating connecting rod 710. A linkage gear 711 is fixedly connected to the arc-shaped wall of the rotating connecting rod 710. The linkage gear 711 meshes with the gear set 706.

[0087] With the above arrangement, manually rotating the adjusting knob 718 can drive the threaded rod 717 to rotate. Thus, the rotation of the threaded rod 717 can drive the fixing block 716 to move, thereby driving the rectangular adjusting rod 709 to move. Then, the movement of the rectangular adjusting rod 709 can drive the rotating connecting rod 710 to move, and further drive the linkage gear 711 to move. Therefore, the position of the linkage gear 711 can be adjusted. By adjusting the position of the linkage gear 711, it can mesh with different gears of the gear set 706. By meshing with different gears, the function of adjusting the rotation speed of the rotating linkage gear 711 can be realized. Specifically, when the first gear 7061 meshes with the linkage gear 711, the rotation of the first gear 7061 can drive the linkage gear 711 to rotate, so that the rotation speed can be synchronously transmitted. When the second gear 7062 meshes with the linkage gear 711, due to the reduction of the number of teeth, the linkage gear 711 will intermittently pause, thus reducing the rotation speed. When the third gear 7063 meshes with the linkage gear 711, due to even fewer teeth, the rotation speed of the linkage gear 711 is further reduced. From the above description, it can be seen that manually rotating the adjusting knob 718 can realize the function of adjusting the position of the linkage gear 711. Thus, by adjusting the position of the linkage gear 711, it can mesh with different gears of the gear set 706 and realize the function of adjusting the rotation speed of the linkage gear 711.

[0088] Specifically, the interior of the rotating link 710 is provided with an inner cavity. An inner rod 712 is slidably inserted into the inner cavity of the rotating link 710. The bottom end of the inner rod 712 extends to the outer surface of the external flushing pipe 4 and is rotatably connected to the external flushing pipe 4. A bevel gear C713 is fixedly connected to the arc-shaped wall of the inner rod 712. The bevel gear C713 meshes with a bevel gear D715. The bevel gear D715 is fixedly arranged at one end of the connecting rod 714. The other end of the connecting rod 714 extends to the auxiliary cleaning unit 8 and is rotatably connected to the auxiliary cleaning unit 8. Through the above arrangement, the rotation of the linkage gear 711 can drive the rotation of the rotating link 710, thereby driving the rotation of the inner rod 712, further driving the rotation of the bevel gear C713, thus driving the rotation of the bevel gear D715, and further driving the rotation of the connecting rod 714.

[0089] As a further technical solution, please refer to Figure 9 and Figure 10 As shown in, the auxiliary cleaning unit 8 includes a cleaning agent storage bin 801, a rectangular pipe 802, a rotating ball 803, a groove 804 and a rotating shaft 805. The inner cavity of the cleaning agent storage bin 801 is filled with a cleaning agent. One end of the rectangular pipe 802 is fixedly connected to the bottom end of the inner cavity of the cleaning agent storage bin 801. The other end of the rectangular pipe 802 extends to the external flushing pipe 4 and is fixedly connected to the external flushing pipe 4. The inner cavity of the rectangular pipe 802 is in communication with the inner cavity of the external flushing pipe 4.

[0090] A spherical cavity is provided in the inner cavity of the rectangular pipe 802. A rotating shaft 805 is fixedly connected to the center position of the rotating sphere 803. The rotating sphere 803 is arranged in the spherical cavity of the rectangular pipe 802 and is rotationally matched with the rectangular pipe 802. A plurality of grooves 804 are formed in the arc-shaped wall of the rotating sphere 803. One end of the rotating shaft 805 is fixedly connected to one end of the connecting rod 714. Through this technical solution, the rotation of the connecting rod 714 can drive the rotating shaft 805 to rotate, thereby driving the rotating sphere 803 to rotate. The cleaning agent in the inner cavity of the cleaning agent storage bin 801 will flow to the rotating sphere 803 due to the action of gravity. Part of the cleaning agent enters the inside of the groove 804. When the groove 804 rotates to the bottom position, the cleaning agent in the inner cavity of the groove 804 falls by gravity and enters the inner cavity of the external flushing pipe 4, realizing the function of automatically adding the cleaning agent. Moreover, the faster the rotating sphere 803 rotates, the more cleaning agent is added per unit time. By controlling the rotation speed of the rotating sphere 803, the function of controlling the added amount of the cleaning agent is realized. Through the adjustment and control of the adjustment part, the function of adjusting the rotation speed of the linkage gear 711 can be realized, and then the rotation speed of the rotating sphere 803 can be controlled, thereby realizing the function of controlling the added amount of the cleaning agent. During the hydraulic circulation flushing process, by adding the cleaning agent to the water flow, the dirt attached to the inner wall of the domestic sewage pipe can be cleaned more thoroughly, the dirt can be removed, and the problem of pollutant deposition in the pipe is significantly reduced. It is particularly suitable for use in sewage pipes with a long service life and a long transportation distance.

[0091] Referring to Figure 1 As shown, this embodiment also provides a usage method of a sewage pipe network sediment control system based on flow velocity segmented improvement, including the following steps:

[0092] a. Conduct a on-site survey of the current situation of the sewage pipe network, determine that the pipe section with an average flow velocity lower than 0.1 m / s and a siltation depth exceeding 1 / 3 of the pipe diameter is the target pipe section 19. Install the sewage pipe network sediment control system in the sewage well 9 at the end of the target pipe section 19, and connect the starting-end sewage well 10 communicating with the starting end of the target pipe section 19 to the external flushing pipe 4;

[0093] b. Transform the sewage well 9, deepen the bottom of the sewage well 9 by 20 - 50 cm and make it into a conical structure, conduct anti-seepage treatment on the deepened part, set a 10 - 30 cm high intercepting weir at the sewage well outlet 18 of the sewage well 9, place the cutting type lift pump 1 at the bottom of the sewage well 9, place the internal circulation pipe 2 in the sewage well 9, and connect the external flushing pipe 4 from the sewage well 9 to the starting-end sewage well 10 through shallow burial on the ground;

[0094] c. Sewage continuously enters the sewage well 9 through other branch pipe inlets 12 and the target pipe section 19. When the starting condition of the cutting type lift pump 1 is reached, the cutting type lift pump 1 pumps a part of the sewage and sprays it to the bottom of the sewage well 9 for scouring, so that the sediment separates from the bottom of the sewage well 9. At the same time, another part of the sewage pumped by the cutting type lift pump 1 is transported to the starting sewage well 10 through the external scouring pipeline 4, and the sewage is pressurized and sprayed into the starting sewage well 10 through the booster nozzle 6. By increasing the water volume and high-pressure scouring, the flow velocity of the pipe section is increased, so that the sediment gradually separates from the pipeline and enters the sewage well 9 at the end of the target pipe section 19 along with the sewage;

[0095] d. When the sediment control system is set in the domestic sewage pipe network in a residential area, set the timing start time period: 9:00 - 11:00, 13:00 - 17:00, and continuously operate the sediment control system of the sewage pipe network;

[0096] e. When the sediment control system is set in the municipal sewage pipe network, set the starting liquid level value and the stopping liquid level value of the cutting type lift pump 1. In response to the liquid level rising to the starting liquid level value, trigger the operation of the sewage pipe network sediment control system. In response to the liquid level dropping to the stopping liquid level value, the sewage pipe network sediment control system stops operating.

[0097] By setting a sediment control system in the main silted pipe section, the present invention solves the problems of pollutant deposition and low collection efficiency caused by too low flow velocity in the whole process of domestic sewage collection and transfer from the source to the end in the way of segmentally increasing the flow velocity of the pipe network.

[0098] Finally, it should be noted that the above specific embodiments are only used to illustrate the technical solutions of the present invention rather than to limit them. Although the present invention has been described in detail with reference to the examples, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention, and they should all be covered within the scope of the claims of the present invention.
