Description

Technical Field

[0001] This application relates to the field of river silt treatment technology, specifically to a river silt treatment device. Background Technology

[0002] River dredging is an important measure to improve water quality and restore river function. During the dredging process, the dredged silt has a very high water content and must be dewatered and reduced in volume before it can be transported and utilized for resources. Currently, the common practice is to use equipment such as belt filter presses and centrifuges to directly dewater the freshly dredged silt. However, river silt has a complex composition and usually contains various solid wastes such as stones, bricks, plastic bags, branches, and aquatic plant debris. These impurities cause many problems during the dewatering process: hard lumps can wear down or damage core components such as dewatering filter belts and spirals; fibrous impurities, such as plastic bags and plant roots, can easily become entangled on rotating parts, causing the equipment to jam or become blocked; and impurities mixed in with the silt cake affect the purity of the silt cake and its subsequent utilization value. Therefore, a river silt treatment device is proposed. Utility Model Content

Detailed Implementation

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings.

[0016] like Figures 1-6 As shown, one embodiment of this application discloses a river silt treatment device, comprising: The cylinder 1 has a rotatable support frame 2 inside it. The support frame 2 is driven to rotate by a driving component. The cylinder 1 is in a vertical direction, and the axis of the support frame 2 is in a vertical direction. The filter cartridge 3 is detachably mounted on the support frame 2 and can rotate with the support frame 2. The filter cartridge 3 and the support frame 2 are coaxially distributed, and the top of the filter cartridge 3 is open. An input mechanism, installed on the cylinder 1, is capable of inputting sludge and water containing impurities into the filter cylinder 3; Both the guide and the output mechanism are installed inside the cylinder 1. The guide can guide the sludge and water without impurities to the output mechanism, and the output mechanism can separate the sludge and water without impurities and discharge them separately. In its initial state, the filter cylinder 3 is installed on the support frame 2. During use, silt and water containing impurities are input into the filter cylinder 3 through the input mechanism. The water can be directly from the river. The support frame 2 is driven to rotate by the drive component, and the filter cylinder 3 rotates with the support frame 2. During this process, impurities are trapped in the filter cylinder 3, while silt and water without impurities fall after passing through the filter cylinder 3. Then, the silt and water without impurities are guided to the output mechanism through the guide component. The output mechanism separates the silt and water without impurities and exports them separately. The exported silt without impurities can be used for subsequent dewatering processes. After use or after a period of continuous use, the drive component and input mechanism are stopped, and the filter cylinder 3 is removed from the support frame 2 to facilitate the dumping out of the trapped impurities. Then, the filter cylinder 3 is reinstalled on the support frame 2. In summary, when used, this application can pre-screen sludge containing impurities, trapping solid waste inside the filter cartridge 3, preventing impurities from entering subsequent dewatering equipment, reducing the risk of wear and damage to core components, preventing equipment jamming or clogging caused by fibrous impurities, extending the service life of the equipment, and ensuring the purity and subsequent utilization value of the sludge cake, thus making it more practical.

[0017] like Figures 3-5 As shown, the specific structure of the driving component of this application is disclosed. The driving component includes a fixed gear 4, a drive motor 5, and a drive gear 6. The fixed gear 4 is disposed on the support frame 2 and is coaxially fixed to the outer wall of the support frame 2. The drive motor 5 is disposed on the cylinder 1 and is fixed to the cylinder 1 with its output shaft in a vertical direction. The drive gear 6 is disposed on the output shaft of the drive motor 5 and meshes with the fixed gear 4. The drive gear 6 is coaxially fixed to the output shaft of the drive motor 5. Referring to the above, when in use, the drive motor 5 is turned on, the output shaft rotates, and the drive gear 6 rotates together. The fixed gear 4 will rotate due to meshing and drive the bearing frame 2 to rotate, so as to drive the bearing frame 2 to rotate.

[0018] like Figures 5-6As shown, a further technical solution of this application is disclosed, which also includes a positioning block 7, a positioning groove 8, a positioning plate 9, a plurality of positioning bolts 10 and a plurality of positioning nuts 11. The positioning groove 8 is opened on the bearing frame 2. The positioning block 7 is set on the filter cylinder 3 and is inserted into the positioning groove 8. The positioning block 7 is fixed on the outer wall of the filter cylinder 3. The positioning plate 9 is fastened on the bearing frame 2 and abuts against the positioning block 7. The positioning plate 9 is annular and coaxially distributed with the bearing frame 2. The positioning plate 9 is fastened on the top of the bearing frame 2. The plurality of positioning bolts 10 are all set on the bearing frame 2. The plurality of positioning bolts 10 are all vertically fixed on the top of the bearing frame 2 and are distributed in a circular array. The plurality of positioning nuts 11 are threaded on the plurality of positioning bolts 10 and abut against the positioning plate 9. The positioning plate 9 is constructed with a number of through holes 12 equal to the number of positioning bolts 10. The through holes 12 are used for the positioning bolts 10 to pass through. Referring to the above, in the initial state, the positioning block 7 is located in the positioning groove 8, the positioning plate 9 is fastened to the top of the support frame 2 and abuts against the positioning block 7, multiple positioning bolts 10 pass through multiple through holes 12 respectively, and multiple positioning nuts 11 are all in a tightened state and abut against the positioning plate 9. The filter cartridge 3 cannot be separated from the support frame 2, so as to realize the installation of the filter cartridge 3. Conversely, by loosening the multiple positioning nuts 11 to move away from the multiple positioning bolts 10, the positioning plate 9 moves upward to move away from the support frame 2 and the positioning block 7, and the filter cartridge 3 moves upward to move away from the support frame 2. The positioning block 7 exits the positioning groove 8, so as to realize the disassembly of the filter cartridge 3.

[0019] like Figures 1-8 As shown, the specific structure of the input mechanism of this application is disclosed. The input mechanism includes two movable frames 13, a water pipe 14, and a sludge pipe 15. Both movable frames 13 are slidably mounted on the cylinder 1. The movable frames 13 slide in the horizontal direction. The water pipe 14 and the sludge pipe 15 are respectively mounted on the two movable frames 13 and fixed on the two movable frames 13. The movable frames 13 are locked in position by locking members. In actual use, the free end of the water pipe 14 is connected to the output end of the water pump, and the free end of the sludge pipe 15 is connected to the sludge suction device. In this embodiment, the water pump and the sludge suction device are not shown in the accompanying drawings. Referring to the above, in the initial state, the two movable frames 13 are close to each other and locked in position by locking components. The water pipe 14 and the sludge pipe 15 are both facing the filter cylinder 3. In use, the free end of the water pipe 14 is connected to the output end of the water pump, and the free end of the sludge pipe 15 is connected to the sludge suction device. Water is supplied to the water pipe 14 by the water pump, and the water enters the filter cylinder 3 through the water pipe 14. Sludge is input into the sludge pipe 15 by the sludge suction device, and the sludge enters the filter cylinder 3 through the sludge pipe 15, so as to realize the input of sludge containing impurities and water into the filter cylinder 3. When the filter cylinder 3 is disassembled, the water and sludge supply is stopped, the position of the movable frame 13 is unlocked by locking components, and the two movable frames 13 are manually driven to slide away from each other. The position of the movable frame 13 is then locked by locking components.

[0020] like Figure 8 As shown, the specific structure of the locking component of this application is disclosed. The locking component includes a locking bolt 16, a first locking hole 17 and a second locking hole 18. The first locking hole 17 and the second locking hole 18 are both opened on the cylinder 1.

The locking bolt 16 is threaded through the movable frame 13 and is inserted into both the first locking hole 17 and the second locking hole 18. The locking bolt 16 is vertical. Referring to the above, when the two movable frames 13 approach each other, the locking bolt 16 is in the lowest position and is engaged with the first locking hole 17, preventing the movable frame 13 from sliding and thus locking the movable frame 13 in position. When the filter cartridge 3 is disassembled, the locking bolt 16 is manually driven to rotate upward to the highest position and out of the first locking hole 17, thereby releasing the movable frame 13 from position locking. When the two movable frames 13 slide away from each other, the locking bolt 16 is manually driven to rotate downward to the lowest position and is engaged with the second locking hole 18, thereby re-locking the movable frame 13 in position.

[0021] like Figures 2-4 As shown, the specific structure of the flow guide of this application is disclosed. The flow guide includes a flow guide cone 19 and a flow guide pipe 20.

One end of the flow guide pipe 20 is connected to the lower part of the flow guide cone 19 and the other end is connected to the output mechanism. The flow guide pipe 20 is vertical and fixed below the flow guide cone 19. Referring to the above, when the sludge and water without impurities fall after passing through the filter cylinder 3, the sludge and water without impurities are guided by the guide cone plate 19, so that they are concentrated and enter the output mechanism through the guide pipe 20, thereby realizing the guidance of the sludge and water without impurities to the output mechanism.

[0022] like Figures 1-4As shown, the specific structure of the output mechanism of this application is disclosed. The output mechanism includes an output cylinder 21, a spiral conveying rod 22, and a conveying motor 23. The output cylinder 21 is horizontal and fixed inside the cylinder body 1. The output cylinder 21 is constructed with an inlet 24, multiple separation holes 25, and an outlet 26.

The outlet 26 is located at one end of the output cylinder 21, and the other end of the guide pipe 20 is connected to the inlet 24. The spiral conveying rod 22 is rotatably disposed inside the output cylinder 21. The spiral conveying rod 22 and the output cylinder 21 are coaxially distributed. The conveying motor 23 is disposed on the cylinder body 1 and the output shaft is connected to the spiral conveying rod 22. The conveying motor 23 is fixed on the cylinder body 1. Referring to the above, during use, the conveyor motor 23 is activated, the output shaft rotates, and the screw conveyor 22 rotates together. The silt and water without impurities enter the output cylinder 21 through the inlet 24. The water continues to fall after passing through multiple separation holes 25, and the silt is conveyed to the outlet 26 by the screw conveyor 22. Finally, the silt is discharged through the outlet 26, so as to separate and export the silt and water without impurities.

[0023] like Figure 3 As shown, a further technical solution of this application is disclosed, which also includes an annular pipe 27 and a plurality of flushing pipes 28. The annular pipe 27 is disposed inside the cylinder 1 and located outside the support frame 2. The annular pipe 27 is fixed inside the cylinder 1 and coaxially distributed with the support frame 2. The plurality of flushing pipes 28 are all connected to the annular pipe 27 and the water outlet faces the support frame 2. In actual use, the free end of the annular pipe 27 is connected to the output end of the water pump. In this embodiment, the water pump is not shown in the accompanying drawings. Referring to the above, during use, the free end of the annular pipe 27 is connected to the water pump, and water is supplied to the annular pipe 27 through the water pump. The water is split into multiple streams in the annular pipe 27 and enters multiple flushing pipes 28 respectively. Then, the water in the flushing pipes 28 is flushed onto the rotating filter cylinder 3 through the outlet end to achieve backwashing of the filter cylinder 3, avoid clogging of the filter cylinder 3, and improve the stability of use.
