[0002] In land reclamation work, river channel improvement is a key project. In the process of river channel improvement, it is inevitable to dredge and clear the river channel to ensure the smooth flow of the river channel. However, small and medium-sized rivers are easy to be polluted, have small water environment capacity, and have poor self-purification ability of water bodies. They can easily become the recipients of residents' domestic sewage, rainwater and garbage, which leads to a large consumption of dissolved oxygen in the water body, causing the water body to be hypoxic and black and smelly.

DETAILED DESCRIPTION

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] Example: Figure 1-Figure 13As shown, the present invention provides a technical solution for a sludge dewatering and drying device for river sludge used for land reclamation, including a drying structure 1, the drying structure 1 including a drying box 11 and a conveying assembly, a guide plate 14 is provided on one side of the conveying assembly; a dewatering structure 2 is installed on the drying box 11, the dewatering structure 2 including a filter box 22, a partition plate 28 and a junction box 214, a sludge diversion assembly is provided between the filter box 22 and the junction box 214, a water flow converging assembly is provided between the sludge diversion assembly and the drying box 11 assembly, a water collecting box 23 is slidably connected inside the filter box 22, filter elements 24 are fixedly connected on both sides of the water collecting box 23, a pneumatic cylinder 25 is fixedly connected on one side of one of the filter elements 24, and the water collecting box 23 is connected to the water flow converging assembly.

[0036] When the sludge dehydration and drying device composed of the drying structure 1 and the dehydration structure 2 is applied to the sludge treatment in the land reclamation project, the feed hopper 21 in the dehydration structure 2 is used to receive the sludge, and the sludge enters the filter box 22 fixedly connected to the bottom of the feed hopper 21 through the feed hopper 21. At this time, the air pressure cylinder 25 in the dehydration structure 2 is controlled to work. Since a sealing sleeve 26 is fixedly connected to one side of the filter box 22, as shown in FIG. Fig.11 As shown, the piston end of the pneumatic cylinder 25 passes through the sealing sleeve 26 and extends into the filter box 22. Therefore, when the pneumatic cylinder 25 is working, the piston end of the pneumatic cylinder 25 moves inside the filter box 22, and the elastic sealing sleeve 26 is wrapped around the outer side of the piston end of the pneumatic cylinder 25, so that there is a good sealing performance between the filter box 22 and the pneumatic cylinder 25.

[0037] The two sides of the water collecting box 23 which is slidably connected inside the filter box 22 are fixedly connected with filter elements 24, and one of the filter elements 24 is fixedly connected to the piston end of the pneumatic cylinder 25. Fig.11 As shown, the working pneumatic cylinder 25 pulls the filter element 24 and the water collecting box 23 to move left and right inside the filter box 22.

[0038] During the left-right movement of the water collecting box 23, since the feed hopper 21 pours the sludge into the filter box 22 near the middle, the left-right movement of the water collecting box 23 will squeeze part of the sludge inside the filter box 22, and the water in the sludge passes through the filter element 24 and enters the water collecting box 23. Since one end of the water guide pipe 9 229 in the water flow converging component extends to the inside of the filter box 22 and is fixedly connected to one of the filter elements 24, as shown in FIG. Fig.11As shown, the hydraulic pressure required for the water inside the water collecting tank 23 to be discharged through the filter element 24 is much smaller than the hydraulic pressure entering the water guiding pipe component 9 229, so the water inside the water collecting tank 23 enters the water guiding pipe component 9 229 and is collected and guided by the water flow collection component to separate and collect the moisture in the sludge; and one end of the water guiding pipe component 8 226 and the other end of the water guiding pipe component 9 229 in the water flow collection component are fixedly connected with a mounting ring 3 227, and a telescopic tube 228 that can be extended and retracted is fixedly connected between the two mounting rings 3 227, so when the water collecting tank 23 and the filter element 24 move left and right, the water guiding pipe component 9 229 moves left and right synchronously, and the telescopic tube 228 is extended and retracted to meet the movement needs of the water guiding pipe component 9 229, while allowing the water guiding pipe component 9 229 to still maintain its diversion function.

[0039] And one end of the two guide pipes 29 in the sludge guide assembly is fixedly connected to the right end of the filter box 22, such as Figure 4 As shown, the two guide pipes 212 are fixedly connected to the junction box 214, and the ends of the guide pipe 29 and the guide pipe 212 are fixedly connected with the mounting ring 1 210, and the two mounting rings 1 210 on the same side are fixedly connected with the water guide pipe 1 211 and the filter 2 213. At this time, one guide pipe 29, one guide pipe 212 and the filter 2 213 between the guide pipe 29 and the guide pipe 2 212 form a sludge movement channel When the water collecting box 23 moves to the right, the sludge inside the filter box 22 is squeezed through the sludge movement channel and enters the inside of the junction box 214; and the two ends of the three filter elements 216 in the sludge diversion assembly are fixedly connected to the mounting ring 215, the mounting ring 215 close to the junction box 214 is fixedly connected to the junction box 214, and one end of the mounting ring 215 away from the junction box 214 is fixedly connected to the guide pipe 3 217, and one end of the guide pipe 3 217 is fixedly connected to the left side of the filter box 22, such as Figure 4 As shown, the filter element three 216 and the guide pipe element three 217 form a sludge flow channel between the filter box 22 and the junction box 214. When the water collecting box 23 moves to the left, the sludge inside the filter box 22 is squeezed through the sludge flow channel and enters the junction box 214, so that the sludge entering the filter box 22 through the feed hopper 21 is guided by the sludge guide component into the junction box 214, and finally discharged to the conveying component in the drying structure 1 through the discharge elbow 219 fixedly connected to the bottom of the junction box 214.

[0040] The water guide pipe 211 is arranged outside the filter element 213, and both ends of the water guide pipe 211 are fixedly connected to the mounting ring 210. Since the inner diameter of the filter element 213 is small, the sludge is still under great pressure when flowing inside the filter element 213, so the water in the sludge is further discharged. Figure 6As shown, water enters the water guide member 1 211 through the filter member 213 for temporary storage; and the outer side of the filter member 3 216 is provided with a water guide member 218, and both ends of the water guide member 218 are fixedly connected to the mounting ring 215. The inner diameter of the filter member 3 216 is relatively small, and the sludge is still subjected to a relatively large pressure during the flow inside the filter member 3 216, as shown in FIG. Figure 5 As shown, the water in the sludge is further discharged, and the water passes through the filter element 3 216 and is temporarily stored in the water guide element 2 218; and the outer bottom of the two water guide elements 1 211 is fixedly connected to the water guide element 3 220, and the two water guide elements 3 220 are respectively fixedly installed at both ends of the water guide element 4 221 in the water flow converging assembly, as shown in FIG. Figure 7 As shown, water pipe five 222 is fixedly connected between the outer bottom of the three water pipe parts two 218 and the water pipe part four 221, so the water temporarily stored in the water pipe part one 211 enters the water pipe part four 221 through the water pipe part three 220, and the water temporarily stored in the water pipe part two 218 enters the water pipe part four 221 through the water pipe part five 222. The sludge diversion component performs secondary water filtration in the sludge diversion process, and the filtered water is collected and drained by the water flow collection component.

[0041] At the same time, the conveying assembly in the drying structure 1 works, and the conveying belt 17 in the conveying assembly is arranged inside the drying box 11, and driving rollers 16 are arranged on both sides of the conveying belt 17, and both ends of the two driving rollers 16 are rotatably connected with the drying box 11, and the forward and reverse motor 15 is fixedly installed on the outside of the drying box 11, and the output end of the forward and reverse motor 15 is fixedly connected with one end of one of the driving rollers 16, and the forward and reverse motor 15, the two driving rollers 16 and the conveying belt 17 constitute an upper conveying device, such as Fig.13 As shown; in the conveying assembly, the conveyor belt 110 is arranged inside the drying box 11, and two driving rollers 19 are arranged inside the conveyor belt 110. Both ends of the two driving rollers 19 are rotatably connected to the drying box 11. The forward and reverse motor 18 is installed on the outside of the drying box 11, and the output end of the forward and reverse motor 18 is fixedly connected to one end of one of the driving rollers 19. The forward and reverse motor 18, the two driving rollers 19 and the conveyor belt 110 constitute the lower conveying equipment; and a change-of-direction roller 111 is arranged on one side of the top of the conveyor belt 110 near the junction box 214 and the discharge elbow 219, as shown Figure 3As shown, the deflection roller 111 connected to the drying box 11 rotates to partially deform the conveyor belt 110. There is a large space between the conveyor belt 110 and the conveyor belt 1 17 at the position of the deflection roller 111, and the bottom end of the discharge elbow 219 is inclined toward the deflection roller 111. The discharge elbow 219 discharges the sludge into the space between the conveyor belt 110 and the conveyor belt 1 17. At this time, the lower conveying equipment and the upper conveying equipment are working, the conveyor belt 17 rotates counterclockwise, and the conveyor belt 110 rotates clockwise. The two drive rollers 19 are arranged one high and one low. The drive roller 19 near the junction box 214 is located at the bottom. The change-direction roller 111 partially deforms the conveyor belt 110. Therefore, the distance between the conveyor belt 17 and the conveyor belt 110 is smaller as the distance from the discharge elbow 219 increases. The sludge is squeezed and dehydrated during the transportation by the lower and upper conveying equipment. A discharge port 13 is provided on the side of the drying box 11 away from the junction box 214. Figure 1 As shown, the lower end of the guide plate 14 passes through the discharge port 13 and extends to the outside of the drying box 11. The guide plate 14 is tilted toward one end and fits with one end of the conveyor belt 110. The dried sludge is separated from the conveyor belt 110 by the action of the guide plate 14. The stripping plate 112 fixedly connected to the bottom of the partition plate 28 fits with the conveyor belt 17. Under the action of the conveyor belt 17, the dried sludge is separated from the conveyor belt 17 and falls onto the guide plate 14. Under the action of the tilted guide plate 14, the dried sludge leaves the drying box 11, completing the sludge drying work.

[0042] During the operation of the conveying assembly, the water squeezed out of the sludge falls to the bottom of the inner cavity of the drying box 11 through the gap on the conveyor belt 2 110, and the water guide pipe 7 224 in the water flow collection assembly is fixedly connected to the bottom of the drying box 11, and the water guide groove 1 225 opened at the top of the water guide pipe 7 224 is arranged at the bottom of the water guide groove 2 230 opened at the bottom of the drying box 11, so that the water in the drying box 11 enters the water guide pipe 7 224 through the water guide groove 1 225, and the water guide pipe 6 223 is fixedly connected to both sides of the top of the water guide pipe 7 224. Figure 7 As shown, the two water-guiding pipe parts six 223 are fixedly connected with the water-guiding pipe part four 221, the water inside the water-guiding pipe part four 221 enters the water-guiding pipe part seven 224 through the water-guiding pipe part six 223, and the water inside the water-guiding pipe part eight 226 is fixedly connected with the outside of one of the water-guiding pipe parts six 223, and the water inside the water-guiding pipe part nine 229 enters the water-guiding pipe part seven 224 through the water-guiding pipe part six 223. Therefore, the water flow intercepted by the two filtrations of the sludge by the dewatering structure 2 and the water squeezed out of the sludge by the drying structure 1 are all collected into the water-guiding pipe part seven 224, and the water flow generated by the three dehydration and drying of the sludge by the sludge dewatering and drying device is collected into the water-guiding pipe part seven 224 by the water flow collection component and then discharged, which is convenient for the centralized collection and treatment of the water in the sludge and reduces the difficulty of sewage recovery.

[0043] The drying structure 1 and the dehydration structure 2 cooperate to dewater the sludge three times. The dehydration intensity is progressively increased to pressurize the sludge for multiple dehydration, thereby increasing the speed of sludge dehydration and ensuring clean dehydration. It can adapt to the drying and dehydration treatment of sludge with high water content in the river during land reclamation.

[0044] In addition, such as Figure 1 As shown, a plurality of supporting legs 12 are fixedly connected to the bottom of the drying box 11, and the plurality of supporting legs 12 support the drying box 11 so that the bottom of the guide plate 14 fixedly installed on the drying box 11 is at a certain distance from the ground, meeting the needs of the staff to collect the dehydrated sludge.

[0045] In addition, such as Fig.13 As shown, the partition plate 28 is arranged at the top of the conveying assembly and is fixedly connected to the drying box 11. The partition plate 28 separates the dehydration structure 2 from the conveying assembly, and the outer wall of the pneumatic cylinder 25 is arranged outside the filter box 22. A plurality of fixed vertical plates 27 are fixedly connected between the outer wall of the pneumatic cylinder 25 and the partition plate 28. The outer wall of the pneumatic cylinder 25 is fixed and cannot move. One end of the water guide pipe member 8 226 passes through the partition plate 28 and extends to the top of the partition plate 28. The water guide pipe member 8 226 is fixedly installed together with the partition plate 28, so that the water guide pipe member 8 226 cannot move, thereby providing support for the contraction of the telescopic tube 228.

[0046] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
