Description

Technical Field

[0001] This invention relates to the field of water ecological cycle, and in particular to a mobile dual-loop water ecological cycle filtration device. Background Technology

[0002] With the increasing demand for ecological management of small enclosed or semi-enclosed water bodies such as urban landscape water systems, rural micro-rivers, aquaculture ponds, and artificial lakes, these water bodies are generally characterized by their scattered distribution and difficulty in constructing civil engineering water treatment facilities. They need to rely on mobile water treatment devices to achieve flexible circulation and purification.

[0003] While existing mobile aquatic ecological filtration devices can separate solid debris such as duckweed, aquatic plants, dead branches, and plastic waste in water bodies, this debris tends to accumulate quickly on the inlet filter screen and the inner walls of the pipes, causing blockages at the inlet and poor water flow. This leads to a decrease in the equipment's purification efficiency, eventually requiring disassembly and cleaning, which increases maintenance costs. At the same time, stagnant or slow-flowing water bodies are prone to the growth of large amounts of bacteria, viruses, and algal spores. Physical filtration and aeration alone cannot eliminate harmful microorganisms, leading to continued deterioration and foul odor in the water, resulting in poor aquatic ecological restoration. Summary of the Invention

[0004] The main objective of this invention is to provide a mobile dual-loop water ecological circulation filtration device, which can effectively solve the problems of easy pipe blockage and low applicability of existing devices.

[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A mobile dual-loop water ecological circulation filtration device includes a mobile frame. An inlet crushing module for water intake is fixedly installed on the mobile frame. An auger conveyor module is fixedly installed at the bottom of the inlet crushing module. A power transmission module is fixedly installed on the outside of the inlet crushing module and the auger conveyor module on the mobile frame. A material collection module is fixedly installed at the outlet of the auger conveyor module on the power transmission module. The power transmission module provides power to the inlet crushing module and the auger conveyor module. An aeration module is fixedly installed at the bottom of the material collection module on the mobile frame. A three-way reversing valve is fixedly connected to the outlet of the aeration module. A sterilization module and a return pipe are fixedly installed on the other two ports of the three-way reversing valve, respectively. The three-way reversing valve is used to selectively guide water from the aeration module to the sterilization module or the return pipe.

[0006] Preferably, the power transmission module includes a servo motor, which is fixedly mounted on a mobile frame. The water inlet crushing module includes a crushing pipe, a cutter holder is fixedly mounted on the top of the crushing pipe, and a crushing cutter is rotatably mounted on the cutter holder. A T-type commutator one and a T-type commutator two are connected in series between the crushing cutter and the output shaft of the servo motor. The servo motor outputs power to the crushing unit and the subsequent transmission unit synchronously through the two sets of T-type commutators, realizing the linkage start and stop of the crushing, conveying, and compression mechanisms, simplifying the power structure and reducing the overall energy consumption of the machine.

[0007] Preferably, a reducer is fixedly mounted on the output shaft of one side of the T-shaped commutator, and a crank is fixedly mounted on the output shaft of the reducer. The other end of the crank is rotatably connected to the moving frame, and a rocker arm is rotatably mounted on the crank. A right-angle commutator is fixedly mounted on the output shaft of the other side of the T-shaped commutator, and a reducer is fixedly connected to the other output shaft of the right-angle commutator. A universal coupling is fixedly connected to the output shaft of the reducer. The right-angle commutator and the universal coupling form an auger power transmission path, and the two transmission paths are driven by the same power source.

[0008] Preferably, the other end of the rocker arm is rotatably connected to a top head, and a pressure cylinder is sleeved on the outer side of the top head. A pressure seat is fixedly installed on the pressure cylinder below the top head. A buffer spring is fixedly connected between the top head and the pressure seat. A compression cylinder is sleeved on the outer side of the pressure cylinder, and a baffle is fixedly installed on the top of the top head. Flexible compression and squeezing are achieved through the buffer spring, which is suitable for adaptive dewatering of solid waste with different densities. The baffle limits the upward stroke of the pressure cylinder and forms an opening and closing coordination with the auger outlet for upward feeding and downward sealing compression, which not only ensures smooth feeding but also improves the compression sealing effect and dewatering efficiency.

[0009] Preferably, the auger conveying module includes an auger cylinder and an auger shaft. The inlet of the auger cylinder is fixedly connected to the outlet at the bottom of the crushing pipe, and the outlet of the auger cylinder is fixedly connected to the side wall of the compression cylinder. A shaft seat is fixedly installed at the top of the auger cylinder, and the auger shaft is rotatably installed on the shaft seat. The other end of the universal coupling is fixedly connected to the auger shaft. The auger conveying unit directly receives the crushed solid-liquid mixture and directionally conveys the material into the compression chamber, avoiding material accumulation and blockage, and ensuring continuous volume reduction treatment of solid waste.

[0010] Preferably, the aeration module includes an aeration mixing chamber and a secondary inlet pipe, the collection module includes a collection pipe, the inlet of the aeration mixing chamber is sealed to the collection pipe and the secondary inlet pipe respectively, a sealing joint is fixedly connected to the side wall of the aeration mixing chamber, an aeration pipe is fixedly connected to the sealing joint, one end of the aeration pipe is located inside the aeration mixing chamber and is provided with air stones, the other end of the aeration pipe is fixedly connected to an aeration pump, and a one-way valve is connected in series between the aeration mixing chamber and the aeration pump, so that the aeration mixing chamber can simultaneously receive the overflow main water flow and the compressed filtered water, realizing the convergence and oxygenation of the two water bodies, and the one-way valve prevents water backflow from damaging the aeration pump and ensures safe operation.

[0011] Preferably, a metal filter screen is fixedly installed inside the collection pipe. The collection pipe is detachably and fixedly connected to the compression cylinder and the aeration mixing chamber by clamps. The quick-release structure of the clamps allows the collection pipe to be replaced when the chamber is full, eliminating the need for on-site slag removal, preventing secondary pollution, and meeting the needs of convenient outdoor maintenance for mobile equipment.

[0012] Preferably, the outer wall of the crushing pipe is provided with a secondary drain outlet and is fixedly connected to the auxiliary water inlet pipe. An overflow filter screen is fixedly installed on the inner side of the secondary drain outlet of the crushing pipe. A rubber scraper that fits the overflow filter screen is provided on the outer side of the crushing blade. The main water flow is diverted through the overflow filter screen. The rubber scraper rotates synchronously with the crushing blade to scrape off the debris on the surface of the filter screen. No manual disassembly and cleaning is required. Long-term operation will not cause blockage and ensure a stable flow of large volume of main water.

[0013] Preferably, the sterilization module includes an ultraviolet sterilization water tank. A water supply pipe and a drain pipe are fixedly connected to the upper and lower ends of the ultraviolet sterilization water tank, respectively. A vent valve is provided on the side of the water supply pipe. The other end of the water supply pipe is fixedly connected to a three-way reversing valve. An activated carbon filter cartridge and a solenoid valve are connected in series on the drain pipe. The other end of the drain pipe is connected to a return pipe. The vent valve balances the air pressure inside and outside the water tank. Ultraviolet sterilization and activated carbon adsorption work together to achieve deep purification. The three-way reversing valve enables dual-mode switching between rapid return and deep purification. Together with the aeration unit, it forms a purification synergy for daily water maintenance and deep sterilization and deodorization, improving the applicability and purification effect of the device.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. This invention provides a mobile dual-loop water ecological circulation filtration device, which solves the problem of solid debris such as duckweed, aquatic plants, plastic, and dead branches clogging the inlet, pipes and filter screen by crushing large-volume debris with a crusher blade and self-cleaning overflow filter screen with a rubber scraper, thereby improving the stability of the equipment during long-term operation.

[0015] 2. This invention provides a mobile dual-loop water ecological circulation filtration device. The solid waste treatment structure uses an auger to convey and then a piston to compress the solid waste. It can squeeze, dehydrate and reduce the volume of solid waste. The collection pipe can be quickly replaced when it is full. Solid waste is transported off-site in a centralized manner to prevent secondary pollution and reduce the difficulty of on-site sludge cleaning and maintenance costs.

[0016] 3. This invention provides a mobile dual-loop water ecological circulation filtration device, which realizes dual-loop purification switching through a three-way reversing valve. The fast loop can directly aerate and return water to meet the daily needs of oxygenation and odor prevention maintenance; the deep loop can be purified by ultraviolet sterilization and activated carbon adsorption, taking into account both daily operation and maintenance and deep treatment, and has a wider range of applicable scenarios.

[0019] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0020] like Figure 1 As shown, this invention provides a mobile dual-loop water ecological circulation filtration device. The whole machine takes the power transmission module 6 as the core driving source. After the water is pretreated by the inlet crushing module 4, it flows in two paths. One path is conveyed by an auger and compressed to complete the solid waste collection. The other path is filtered through overflow and enters the aeration module 9 for oxygenation. Then, the three-way reversing valve 3 realizes the dual-mode switching of rapid return or deep sterilization and purification. Finally, it returns to the original water body through the return pipe 2, completing the mobile dual-loop water ecological circulation filtration.

[0021] like Figure 2 and Figure 6 As shown, this invention provides a mobile dual-loop water ecological circulation filtration device. The water to be treated enters the crushing pipe 41. The servo motor 61 of the power transmission module 6 drives the crushing blade 43 to rotate at high speed around the blade holder 42 via T-type commutator 1 65 and T-type commutator 2 615, which shears and crushes large solid debris such as duckweed, aquatic plants, plastic, and dead branches in the water. The overflow filter screen 44 on the side wall of the crushing pipe 41 filters and diverts the main water flow. The rubber scraper on the outside of the crushing blade 43 rotates synchronously with the blade body, continuously scraping off the debris attached to the surface of the overflow filter screen 44 to prevent the filter screen from clogging and ensure that the main water flow flows stably into the aeration module 9. The crushed solid-liquid mixture falls into the bottom auger conveying module 5.

[0022] like Figure 3 and Figure 4 As shown, this invention provides a mobile dual-loop water ecological circulation filtration device. A servo motor 61 drives a crank 63 to rotate via a reducer 62. The crank 63, through a rocker arm 64, drives the top head 612 to perform reciprocating linear motion. When the top head 612 moves upward, it pulls the pressure cylinder 69 up along the compression cylinder 614, exposing the discharge port of the auger cylinder 51, thus completing material feeding. When the top head 612 moves downward, it compresses the buffer spring 611. The buffer spring 611 can adjust according to the density of the solid waste. The adaptive extension and retraction allows the pressure cylinder 69 to maintain a uniform extrusion pressure on the mixture in the collection pipe 71, ensuring that the solid waste is fully dehydrated and its volume reduced, while preventing the collection pipe 71 or filter screen from cracking due to excessive extrusion pressure. The pressure cylinder 69 is pushed downward by the pressure seat 610 to block the discharge port and extrude water from the mixture in the collection pipe 71. The baffle 613 restricts the upward stroke of the pressure cylinder 69 to ensure stable operation of the mechanism. The water squeezed out flows into the aeration module 9 through the filter screen of the collection pipe 71, and the solid waste is compressed and its volume reduced.

[0023] like Figure 4As shown, this invention provides a mobile dual-loop water ecological circulation filtration device. The solid-liquid mixture after crushing in the crushing pipe 41 enters the auger cylinder 51 under gravity. The servo motor 61 drives the auger shaft 52 to rotate around the shaft seat 53 via the T-type commutator 615, the right-angle commutator 66, the reducer 67, and the universal coupling 68. The solid-liquid mixture is pushed directionally along the auger cylinder 51 to the inside of the compression cylinder 614 through the spiral blades, providing a continuous and stable material supply for the subsequent lifting and compression mechanism and avoiding material accumulation and blockage. The collection pipe 71 is used to receive the compressed solid waste mixture. The metal filter screen 72 inside the pipe filters and separates the squeezed water. The water flows into the aeration mixing chamber 91, and the solid waste is retained in the collection pipe 71. The collection pipe 71 is detachably connected to the compression cylinder 614 and the aeration mixing chamber 91 by clamps. After the solid waste is filled, the old collection pipe can be quickly removed and replaced with a new collection pipe. The compressed solid waste in the old pipe is centrally transported and disposed of.

[0024] like Figure 5 As shown, this invention provides a mobile dual-loop water ecological circulation filtration device. The collection pipe 71 receives the compressed solid waste mixture, and the metal filter screen 72 inside the pipe filters and separates the squeezed water. The water flows into the aeration mixing chamber 91, while the solid waste is retained in the collection pipe 71. The collection pipe 71 is detachably connected to the compression cylinder 614 and the aeration mixing chamber 91 by clamps. After the solid waste is filled, the old collection pipe can be quickly removed and replaced with a new collection pipe. The compressed solid waste in the old pipe is centrally transported off-site for disposal, eliminating the need for on-site slag removal and preventing secondary pollution.

[0025] like Figure 7 As shown, this invention provides a mobile dual-loop water ecological circulation filtration device. After aeration, the water enters the ultraviolet sterilization tank 82 through the water supply pipe 81. The air valve 83 balances the air pressure inside and outside the tank to ensure smooth water intake. The ultraviolet lamps in the tank sterilize and disinfect the water at regular intervals, killing bacteria, viruses, and algal spores. After the set liquid level and sterilization time are reached, the solenoid valve 86 opens, and the water flows through the drain pipe 84 through the activated carbon filter cartridge 85, adsorbing and removing odors and small molecule organic matter from the water. After purification, the water flows into the return pipe 2 and returns to the original water body, completing the deep purification.

[0026] The working principle of this mobile dual-loop water ecological circulation filtration device will be explained in detail below.

[0027] like Figure 1-7 As shown, the water to be treated enters the crushing pipe 41, the crushing blade 43 crushes large-volume debris, and the solid-liquid mixture is transported to the compression cylinder 614 via the auger shaft 52; at the same time, the crushing blade 43 is equipped with a rubber scraper to automatically clean the overflow filter screen 44, ensuring the stable flow of the main water. The crank-rocker mechanism drives the pressure cylinder 69 to reciprocate downwards, squeezing and dehydrating the mixture in the collection pipe 71. The water is separated by the metal filter screen 72, and the solid waste is compressed and reduced in volume. When the collection pipe 71 is full, it is quickly replaced by clamps, and the solid waste is transported out in a centralized manner, removing water pollutants from the source.

[0028] The main water flows through the overflow filter 44 and the auxiliary inlet pipe 92 into the aeration mixing chamber 91. The aeration pump 96 completes the oxygenation of the water, and the one-way valve 94 protects the aeration equipment and eliminates the interference of foam on subsequent sterilization. The three-way reversing valve 3 connects the aeration mixing chamber 91 and the return pipe 2, allowing the oxygenated water to flow back directly, achieving daily water circulation, oxygenation, and odor prevention maintenance. The three-way reversing valve 3 also connects the aeration mixing chamber 91 and the ultraviolet sterilization water tank 82, allowing the water to flow back after deep treatment by ultraviolet sterilization and activated carbon adsorption, achieving sterilization and deodorization.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
