Description

Background Technology

[0001] Most small and medium-sized reservoirs are non-flowing water, and the water flowing through the river channels often becomes non-flowing due to blockages in narrow sections. This leads to the surface being covered by floating plants and algae, causing changes in water quality, which is detrimental to water storage and irrigation. Summary of the Invention

[0003] Component II includes a roller rotatably mounted at the inlet end of a fixed housing. Both ends of the roller are coaxially constructed with rotating rods, and a pulley is mounted on one of the rotating rods. The pulley is driven by a power motor to drive the roller. Two helical blades with opposite directions of rotation are constructed on the outer peripheral wall of the roller. Each helical blade extends helically along the axial direction of the roller to the middle of the roller.

[0004] Optionally, the collection mechanism is connected to a solid-liquid separator. Preferably, the circumferential surface of the roller is evenly distributed with through holes for small-volume floating objects to enter the roller. One end of a suction pipe extends into the roller from one axial end, and the suction pipe bends downward and extends along the axial direction of the roller to the other end. Suction holes are evenly opened on the circumferential surface of the part of the suction pipe that extends into the roller.

[0036] This invention discloses a system for treating pollutants in small and medium-sized reservoirs and rivers, such as... Figure 1As shown, the invention includes a traveling device, a conveying and crushing mechanism, a first collecting mechanism, and a separation and recovery mechanism. The traveling device includes a boat that travels on the water surface or a motor vehicle that travels along the side of the river. The conveying and crushing mechanism is installed on the traveling device, and the operator can change the angle of the conveying and crushing mechanism according to specific conditions and needs. This allows debris at different locations on the water surface or at the bottom of the reservoir to be collected by the first collecting mechanism and supplied to the conveying and crushing mechanism. When the first collecting mechanism is on the water surface, it collects floating debris; when it is at the bottom, it collects silt. The first collecting mechanism is installed at the inlet end of the conveying and crushing mechanism, and the separation and recovery mechanism is detachably connected to the outlet end of the conveying and crushing mechanism for separating the crushed material from the water. The working principle of this invention is as follows: This invention collects floating aquatic plants and algae on the water surface or silt at the bottom of the water through a first collection mechanism. These floating objects or silt enter the conveying and crushing mechanism, which conveys the floating objects or silt and crushes them before supplying them to the separation and recycling mechanism. The separation and recycling mechanism separates the crushed floating objects from the water, or separates the silt from the water contained within it. Then, the separated water is discharged back into the reservoir or river, and the floating objects or silt are collected and finally unloaded to the dam.

[0037] As a preferred embodiment of the present invention, such as Figure 2 As shown, a frame 102 is installed on the mobile equipment. The aforementioned conveying and crushing mechanism is pivotally connected to the frame 102. Under the control of the operator, the conveying and crushing mechanism can swing up and down along its pivot axis, enabling the first collection mechanism to collect different floating objects on the water. In this embodiment, the bottom end of the frame 102 is fixedly connected to a rotating chassis 100. The rotating chassis 100 is rotatably connected to the mobile equipment via a vertically arranged rotating shaft 101. That is, the frame 102 can rotate along the axis of the rotating shaft 101 with the rotating chassis 100, thereby enabling the conveying and crushing mechanism to drive the first collection mechanism to collect floating objects within a horizontal range on the water surface.

[0038] As a preferred embodiment of the present invention, such as Figure 1-11 , Figure 14 As shown, the first collection mechanism includes a fixed shell 400 and a waste collection assembly. The fixed shell 400 has a connection port 405, and an adapter sleeve 500 is detachably connected to the inlet end of the conveying and crushing mechanism. The adapter sleeve 500 has a connector 501, which is detachably mounted at the connection port 405. The conveying and crushing mechanism communicates with the inner cavity of the fixed shell 400. The waste collection assembly is mounted at the end of the fixed shell 400 away from the conveying and crushing mechanism. The working principle of this embodiment is as follows: the waste collection assembly collects aquatic plants from the water surface or silt from the bottom of the reservoir, and then supplies it to the conveying and crushing mechanism via the adapter sleeve 500 for subsequent conveying and crushing operations.

[0039] As a preferred embodiment of the present invention, the waste collection component includes various implementations, two of which are listed below:

[0040] The first implementation method is as follows: Figure 1-3 As shown, the waste collection assembly includes a roller 600, which is rotatably mounted at the inlet end of a fixed housing 400. Rotating rods 602, coinciding with the axis of the roller 600, are constructed at both ends of the roller 600. A pulley 603 is mounted on one of the rotating rods 602, which is driven by a power motor to move the roller 600. Specifically, the power motor is mounted on one side of the fixed housing 400 and is waterproofed. Another pulley is mounted on the output shaft of the power motor, and the two pulleys are connected by a belt drive. Two spiral blades 601 with opposite directions of rotation are constructed on the outer peripheral wall of the roller 600. Each spiral blade 601 extends spirally along the axis of the roller 600 to the middle of the roller 600. The working principle of this embodiment is as follows: the operator adjusts the roller 600 to the water surface or bottom according to the actual situation, and by controlling the power motor, collects aquatic plants on the water surface or silt at the bottom. This embodiment is designed to facilitate the collection of small floating objects on the water surface, such as algae. Figure 1-3 As shown, the circumferential surface of the roller 600 is evenly distributed with through holes for small floating objects to enter the interior of the roller 600. One end of a sludge suction pipe 700 extends into the roller 600 from one axial end, and the end of the sludge suction pipe 700 is bent downward and extends along the axial direction of the roller 600 to the other end of the roller 600. Suction holes are evenly opened on the circumferential surface of the part of the sludge suction pipe 700 that extends into the roller 600. The other end of the sludge suction pipe 700 is connected to a rubber tube 704, which is connected to a sludge pump 701. The outlet of the sludge pump 701 is connected to a solid-liquid separator. When using roller 600 to collect aquatic plants and algae from the water surface, some small-sized algae or fragmented aquatic plants cannot pass through roller 600 to the conveying and crushing mechanism, resulting in these small-sized debris not being collected. This embodiment addresses this by creating through holes in roller 600, ensuring the water inside roller 600 remains in the lower middle part of roller 600. Furthermore, under the suction of suction pipe 700, small-sized floating debris on the water surface can smoothly enter roller 600 and be sucked into the solid-liquid separator. The specific structure of the solid-liquid separator in this embodiment is as follows: Figure 15As shown, the solid-liquid separator includes a separation tank 702 and a filter cylinder 703. The upper and lower parts of the separation tank 702 are respectively provided with a sludge inlet 706 and a liquid outlet 707. A first control valve 708 and a second control valve 709 are respectively installed on the sludge inlet 706 and the liquid outlet 707. The filter cylinder 703 is assembled inside the separation tank 702 from the upper end of the separation tank 702, and the bottom of the filter cylinder 703 closes the upper opening. In this embodiment, to improve the filtration effect, the bottom of the filter cylinder 703 is a downwardly concave arc-shaped curved surface 705. The inlet 706 is connected to the inner cavity of the filter cylinder 703, and the outlet 707 is located below the bottom surface of the filter cylinder 703. Floating debris is injected into the filter cylinder 703 through the suction pipe 700. The floating debris rises, and the water is discharged from the separation tank 702 through the outlet 707. Some small debris sinks to the bottom of the filter cylinder 703 and is intercepted. When the discharge rate of the outlet 707 is low, it indicates that the filter cylinder 703 has been filled with debris or that the filter cylinder 703 is blocked. The operator can stop the suction pump 701 and use a lifting device to lift the filter cylinder 703 out of the separation tank 702.

[0041] The second implementation method is as follows: Figure 4-6As shown, the waste collection assembly includes two vertically arranged shafts 604, which are rotatably connected side-by-side to the inlet end of the fixed housing 400. Feeding components that rotate with the shafts 604 are mounted on each shaft 604. Worm gears 617 are mounted on the same side of each shaft 604. A different power motor, also waterproof, is mounted on the fixed housing 400. A worm gear 618 is coaxially mounted on the output shaft of this power motor. The worm gear 618 has helical transmission teeth 619 with opposite directions of rotation located at the two worm gears 617. When the power motor drives the worm gear 618 to rotate, the two shafts 604 rotate towards each other under the transmission of the worm gears 617. The working principle of this embodiment is as follows: the power motor drives the worm gear 618 to rotate the two shafts 604 towards each other, thereby causing the feeding components to scoop floating objects on the water surface or underwater silt into the conveying and crushing mechanism. The preferred structure of the feeding assembly is as follows: the feeding assembly includes multiple fixed discs 605 sequentially mounted on the shaft 604 and rotatable with the shaft 604. Specifically, an assembly hole 608 is provided at the center of the fixed disc 605. The cross-section of the shaft 604 is a regular hexagon, and the shape of the assembly hole 608 is adapted to the shaft 604. This facilitates installation and enables synchronous rotation of the fixed disc 605 and the shaft 604. Cutting blades 606 or elastic levers 609 extending in a wave-like manner are evenly arranged on the outer circumferential surface of the fixed disc 605. The fixed discs 605 on the two shafts 604 are staggered, which facilitates the collection of dirt during the relative rotation of the cutting blades 606 or elastic levers 609. In this embodiment, to prevent hard debris from getting stuck on the elastic lever 609, the elastic lever 609 rotates with the fixed plate 605 to the corresponding side wall of the fixed shell 400, and bends elastically upon contact with the side wall. This elastic bending of the lever 609 dislodges any hard objects stuck within it. When using the cutting blade 606, this embodiment cuts large or intertwined aquatic plants into segments and conveys the cut aquatic plants to the conveying and crushing mechanism. When using the elastic lever 609, its elasticity conveys surrounding tough aquatic plants to the conveying and crushing mechanism, which then cuts and crushes these plants, ultimately collecting them. This embodiment also prevents large stones or hard branches from getting stuck between the two fixed plates 605. Figure 7-9As shown, an elastic element is assembled between two adjacent fixed discs 605 on the same shaft 604. The elastic element includes a spring 610 fitted onto the shaft 604, with connecting discs 611 fixedly connected to both ends of the spring 610. Assembly grooves 607 are respectively formed on the end faces of the fixed discs 605. The connecting discs 611 are installed in the assembly grooves 607 and fastened to the fixed discs 605 by bolts. The working principle of this embodiment is as follows: when a large, hard object is placed between the two fixed discs 605, the spring 610 elastically extends, and as the fixed discs 605 rotate, the large, hard object is dislodged from the fixed discs 605.

[0042] As a preferred embodiment of the present invention, such as Figure 12-13 As shown, the first collection mechanism includes a connecting seat 612 detachably installed at the inlet end of the conveying and crushing mechanism. The first collection mechanism can be assembled inside the fixed shell 400 or without the fixed shell 400. The first collection mechanism includes the connecting seat 612, the guide rod 615, and multiple collecting elastic rods 614. The guide rod 615 is installed at the center of the connecting seat 612, and guide blades 616 extending spirally along its axis are constructed on the guide rod 615. Multiple connecting strips 613 are arranged at intervals along the circumference of the connecting seat 612. The collecting elastic rods 614 are fixedly installed on the corresponding connecting strips 613. The collecting elastic rods 614 are evenly arranged along the circumference of the connecting seat 612 and have a wavy rod structure. One end of each collecting elastic rod 614 gradually opens outward from the connecting seat 612. The working principle of this embodiment is as follows: When encountering vigorous aquatic plants or a large amount of aquatic plants deposited at the bottom of the water, the conveying and crushing mechanism drives the connecting seat 612 to rotate. During the rotation of the connecting seat 612, the collecting elastic rod 614 rotates. The collecting elastic rod 614 collects the aquatic plants or stirs up the silt. Then, the collected or disturbed aquatic plants and silt are conveyed to the conveying and crushing mechanism through the guide blades 616 on the guide rod 615 for subsequent conveying, crushing and recycling operations.

[0043] As a preferred embodiment of the present invention, such as Figure 1-2 As shown, when the first collection mechanism collects floating objects on the water surface, wing plates 401 are respectively constructed on both sides of the upper end of the fixed shell 400. An inflatable rubber float 406 is installed on the lower part of each wing plate 401. The operator can control the inflation amount of the inflatable rubber float 406 according to the specific situation, so as to achieve the optimal position of the first collection mechanism on the water surface with the cooperation of the frame 102, and effectively collect floating objects on the water surface.

[0044] As a preferred embodiment of the present invention, such as Figure 5As shown, material-gathering plates 402 are pivotally connected to both sides of the fixed shell 400. The end of each material-gathering plate 402 away from the fixed shell 400 opens outwards. A first stop 403 and a second stop 404 are fixedly provided on the outer side walls of the fixed shell 400 where the corresponding material-gathering plates 402 are close to each other. When the material-gathering plates 402 open and perform material-gathering operations, the first stop 403 and the second stop 404 abut against each other. The working principle of this embodiment is as follows: as the fixed shell 400 moves forward with the traveling device, the two material-gathering plates 402 open and collect the aquatic plants or silt within their covered area, which are then collected by the first collection mechanism.

[0045] In a preferred embodiment of the present invention, when the water surface is covered with small-volume floating objects or algae, a second collection mechanism for collecting these small-volume floating objects is installed on the traveling device. This second collection mechanism includes a collection plate 1001 and a floating object suction mechanism. A receiving seat 1002 is constructed in the center of the back of the collection plate 1001. The collection plate 1001 is connected to the traveling device via a connecting arm that connects to the traveling device and the receiving seat 1002. The collection plate 1001 is located at the forward end of the traveling device, with its upper part extending above the middle of the plate. The cross-section of the collection plate 1001 is arc-shaped, and the opening of the plate faces away from the traveling device. The floating object suction mechanism is disposed within the space formed by the recess in the collection plate 1001 and is movably connected to the collection plate 1001. The floating object suction mechanism can move vertically. The specific structure of the floating object suction mechanism in this embodiment is as follows: Figures 19-20As shown, the floating debris suction mechanism includes a fixed cover 1006 movably connected to the sludge collection plate 1001. The lower end of the fixed cover 1006 has a large-diameter, downward-facing horn-shaped cover 1007. Filter holes are evenly distributed on the horn-shaped cover 1007. A suction pipe 1009 is constructed on the fixed cover 1006, with one end extending into the horn-shaped cover 1007 and the other end connected to the inlet of a suction pump. The suction pump and the aforementioned sludge pump 701 can be a single water pump, requiring only two independent pipe connections. Valves can be installed on each pipe to control the operation of the floating debris suction mechanism or the sludge suction pipe 700. The suctioned water containing impurities is transported to a solid-liquid separator for separation. In this embodiment, to facilitate the full collection of floating algae and separate large-volume debris, an upward-extending filter screen 1010 and a downward-extending obstruction member 1012 are connected to the large-diameter end of the horn cover 1007. The filter screen 1010 is a cylindrical structure fitted over the horn cover 1007. A connecting flange 1011 extending radially inward is constructed at the lower end of the filter screen 1010. The connecting flange 1011 is fixed to the large-diameter end of the horn cover 1007 by bolts. The top of the filter screen 1010 is higher than the top of the horn cover 1007. The obstruction member 1012 extends below the water surface. The filter screen 1010 is used to block large-volume aquatic plants above the water surface, preventing clogging of the filter holes of the horn cover 1007; the obstruction member 1012 is used to block debris floating above the water surface that does not sink outside the horn cover 1007. Furthermore, since the floating debris suction mechanism is connected to the sludge collection plate 1001 in a vertically movable manner, the floating debris suction mechanism can rise and fall on the water surface within a certain height range. This prevents the floating debris suction mechanism from sinking or rising beyond the predetermined range during its movement, thus avoiding the inability to completely adsorb the floating algae on the water surface. Under normal circumstances, an air ring can be installed at the connection between the filter screen 1010 and the blocking component 1012 to keep the floating debris suction mechanism at a predetermined depth on the water surface, that is, the part of the horn cover 1007 extending out of the water surface is within the predetermined range. In this embodiment, the connection between the fixing cover 1006 and the sludge collection plate 1001 is as follows: Two fixing rods 1003 are constructed on the inner side wall of the sludge collection plate 1001. The ends of these two fixing rods 1003 away from the sludge collection plate 1001 are close to each other, and the ends of the two are hinged to a fixing ring 1004. The fixing ring 1004 is composed of two semicircles. The ends of the two semicircles that are close to each other respectively form connecting ears 1005. An annular groove 1008 that coincides with its axis is constructed on the outer surface of the fixing cover 1006. The two semicircles are bolted together by the connecting ears 1005 to be fitted into the annular groove 1008. The width of the annular groove 1008 is greater than the width of the fixing ring 1004, and the fixing ring 1004 can move up and down in the annular groove 1008. In this way, the floating object suction mechanism floats up and down within a predetermined range.

[0046] As a preferred embodiment of the present invention, such as Figure 1-14 As shown, the conveying and crushing mechanism includes a housing 200, an end cap 203, a conveying section, a crushing section, and a grinding section. The housing 200 has a cylindrical structure. One axial end of the housing 200 is detachably connected to the first collecting mechanism, and the other end of the housing 200 is sealed by the end cap 203. The conveying section, crushing section, and grinding section are connected end to end along the conveying direction of the waste and are all assembled inside the housing 200. A discharge port 201 is constructed on the housing 200 at the tail end of the grinding section. The working principle of this embodiment is as follows: the first collecting mechanism collects the waste and conveys it to the conveying and crushing mechanism. The waste is conveyed by the conveying section of the conveying and crushing mechanism to the crushing section. The crushing section crushes large-volume debris such as aquatic plants. The crushed debris enters the grinding section, where it is ground and then collected by the separation and recovery mechanism, which separates the solid and liquid components.

[0047] As a preferred embodiment of the present invention, such as Figure 14 As shown, the aforementioned conveying section, crushing section, and grinding section are all constructed on a mounting shaft 301 that coincides with the axis of the housing 200. The end of the mounting shaft 301 furthest from the collecting mechanism is coaxially connected to the output shaft of the drive motor 300. The mounting shaft 301 is a segmented rod-shaped structure, with the ends of adjacent rod-shaped structures detachably connected by a threaded connection. The conveying section, crushing section, and grinding section are respectively constructed on corresponding rod-shaped structures. The conveying section includes conveying blades 302 constructed on the mounting shaft 301, which extend spirally along the axis of the mounting shaft 301. The crushing section includes multiple sets of crushing rods 304 constructed on the mounting shaft 301 and spaced apart along its axial direction. The multiple crushing rods 304 constituting each set of crushing rods 304 are evenly arranged circumferentially along the mounting shaft 301, and the crushing rods 304 of adjacent sets of crushing rods 304 are staggered. The grinding section includes a grinding body constructed on the mounting shaft 301. The grinding body includes an integrally formed coarse grinding section 305 and a fine grinding section 306. The axial section of the outer surface of the coarse grinding section 305 is a parabola with its vertex near the crushing section. The fine grinding section 306 includes a cylindrical structure connected to the large-diameter end of the coarse grinding section 305. The working principle of this embodiment is as follows: the waste is gradually conveyed to the crushing section through the conveying blades 302 of the conveying section. The crushing section uses a crushing rod 304 or a crushing blade instead of a crushing rod 304 to crush the waste into small segments. These small segments of debris are then ground by the coarse grinding section 305 of the grinding section. Since the cross-section of the coarse grinding section 305 is parabolic, these small segments of debris are gradually ground into smaller pieces. Furthermore, since the outer surface of the coarse grinding section 305 is smoothly transitioned, it is avoided that debris gets stuck in the coarse grinding section 305, causing damage to the equipment. The coarse powder of the debris after being ground by the coarse grinding section 305 is ground into fine powder by the fine grinding section 306 and enters the separation and recovery mechanism along with water for solid-liquid separation.

[0048] As a preferred embodiment of the present invention, such as Figure 2 As shown, the housing 200 includes a cylindrical body and multiple extension tubes 202 detachably connected to the end of the cylindrical body away from the collection mechanism. These extension tubes 202 coincide with the axis of the cylindrical body and are connected end to end in sequence. Operators can appropriately lengthen the cylindrical body according to different reservoir depths and the requirements for conveying and pulverizing effects, and then connect multiple conveying sections end to end, maintaining a continuous state after the conveying blades 302 of adjacent conveying sections are connected.

The fixing edge 901 is fitted into the mounting groove 802 and fixed by the limiting pins 803 with a nut. This grinding... Afterwards, the waste and water are gradually injected into the separation and recovery tank 800 through the hopper 900. When there is a lot of water in the separation and recovery tank 800, the end of the hydraulic rod of the hydraulic cylinder is fixedly connected to the top pressure plate 801 through the mounting groove 802, so that the hydraulic cylinder drives its hydraulic rod to move downward and compact the debris in the separation and recovery tank 800. The water in the separation and recovery tank 800 overflows into the separation and recovery tank 800 part above the top pressure plate 801 through the holes of the top pressure plate 801. Then, the water is pumped away by equipment such as a water pump, or a drain pipe is constructed on the upper part of the separation and recovery tank 800, and a drain valve is installed on the drain pipe. By opening the drain valve, the water in the separation and recovery tank 800 is discharged. In this embodiment, in order to avoid the top pressure plate 801 from tilting, a transmission edge 804 is formed on the edge of the top pressure plate 801. In order to prevent the transmission edge 804 from damaging the inner wall of the separation and recovery tank 800, multiple wear-bearing rings 805 are embedded on the transmission edge 804.
