Description

Technical Field

[0001] This utility model relates to the field of silt treatment technology, and in particular to a rapid dewatering and solidification device for river silt. Background Technology

[0002] River dredging generally refers to the management of river channels and is a type of water conservancy project. It involves using mechanical equipment to blow and stir up the silt deposited on the riverbed into a turbid water state, which is then carried away by the river water, thereby achieving the purpose of clearing the waterways.

[0003] For example, Chinese utility model patent (CN 214142057 U) discloses a rapid dewatering and solidification device for river silt, which describes: "After the silt enters the storage tank, it is first further filtered through the second filter hole. Then, the stepper motor drives the rotating shaft to rotate, thereby driving the rotating drum to rotate, so that the silt enters the upper end of the first filter hole. At this time, the hydraulic pump is started to drive the extrusion plate at one end of the hydraulic rod to extrude the silt in the storage tank. The silt is filtered again through the first filter hole to remove water. Then, the stepper motor drives the rotating drum to rotate again, so that the dewatered silt passes through the through hole and falls onto the discharge plate and slides out. The wastewater filtered by the first and second filter holes is collected through the first funnel and enters the wastewater tank." It also describes the technical problem that "the existing device has low dewatering efficiency for silt and is difficult to meet the requirements of this large-scale silt treatment."

[0004] In summary, it is known that the existing technology uses compression of silt and filter screen to remove water from the silt. However, this method has the following technical problems: the compression process puts a great burden on the filter screen, causing it to deform, which in turn reduces the filtration effect of the filter screen, increases the frequency of filter screen replacement, and thus increases the operating cost of the device. Therefore, this application proposes a rapid dewatering and solidification device for river silt, providing a new technical solution to solve the technical problems mentioned in the above patent. Utility Model Content

[0005] Based on this, it is necessary to provide a rapid dewatering and solidification device for river silt to address the aforementioned technical problems. This device utilizes a first motor to drive a bidirectional threaded rod to rotate, which in turn causes two active clamping plates to move towards the center under the constraint of a fixed rod. With the assistance of the driven clamping plates, the silt on the fixed screen plate is squeezed, forcing water and some small particles from the silt to the bottom of the fixed screen plate, achieving initial dewatering. This process reduces the pressure on the fixed screen plate, decreases wear and tear during use, reduces the frequency of device maintenance, and lowers the operating cost. Furthermore, the silt, after undergoing primary filtration, comes into contact with the movable screen plate, further reducing the pressure on the movable screen plate during use.

[0006] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0007] A rapid dewatering and solidification device for river silt is used to rapidly dewater and solidify river silt to reduce the burden on filter screens.

[0008] The rapid dewatering and solidification equipment for river silt specifically includes: a device shell, a dewatering mechanism on the top of the device shell, a screening mechanism inside the device shell, a feed inlet fixedly connected to the top of the device shell, a discharge port on the outside of the device shell, and a discharge outlet fixedly connected to the inside of the device shell.

[0009] The dehydration mechanism includes a protective shell fixedly connected to the top of the device housing, a first motor fixedly connected to the top of the device housing, and a fixed sieve plate fixedly connected to the inside of the device housing.

[0010] In a preferred embodiment of the rapid dewatering and solidification equipment for river silt provided by this utility model, the output end of the first motor is rotatably connected to a bidirectional threaded rod, the bidirectional threaded rod is rotatably connected inside the protective shell, and a fixing rod is fixedly connected inside the protective shell.

[0011] In a preferred embodiment of the rapid dewatering and solidification device for river silt provided by this utility model, the external thread of the bidirectional threaded rod is connected to an active clamping plate, the active clamping plate is slidably connected to the outside of the fixed rod, and the external rotatably connected to the active clamping plate is a first roller, which is rotatably connected to the inside of the device housing.

[0012] In a preferred embodiment of the rapid dewatering and solidification equipment for river silt provided by this utility model, a driven clamp is slidably connected inside the outer shell of the device, and a second roller is rotatably connected outside the driven clamp, with the second roller rolling inside the outer shell of the device.

[0013] As a preferred embodiment of the rapid dewatering and solidification equipment for river silt provided by this utility model, the screening mechanism includes a movable screen plate movably connected inside the device housing, a first elastic telescopic rod closely attached to the outside of the movable screen plate, the end of the first elastic telescopic rod away from the movable screen plate being fixedly connected to the inside of the device housing, and a baffle plate being fixedly connected to the bottom of the movable screen plate.

[0014] In a preferred embodiment of the rapid dewatering and solidification equipment for river silt provided by this utility model, a receiving plate is fixedly connected inside the outer shell of the device, a second motor is fixedly connected to the top of the receiving plate, a disc is fixedly connected to the output end of the second motor, a connecting rod is fixedly connected to the outside of the disc, and a rotating wheel is rotatably connected to the end of the connecting rod away from the disc.

[0015] In a preferred embodiment of the rapid dewatering and solidification equipment for river silt provided by this utility model, a locking rod is slidably connected inside the outer shell of the device, a U-shaped plate is movably connected inside the outer shell of the device, the locking rod is movably connected inside the U-shaped plate, a fixing block is fixedly connected outside the locking rod, a return spring is fixedly connected outside the fixing block, and the end of the return spring away from the fixing block is fixedly connected inside the outer shell of the device.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] The river silt rapid dewatering and solidification equipment provided by this utility model utilizes a first motor to drive a bidirectional threaded rod to rotate, which in turn drives two active clamping plates to move closer together under the constraint of a fixed rod. With the assistance of the driven clamping plates, the silt on the fixed screen plate is squeezed, forcing the water and some small particles in the silt to the bottom of the fixed screen plate, thus achieving preliminary dewatering. This process reduces the pressure on the fixed screen plate, reduces the wear and tear on the fixed screen plate during use, reduces the maintenance frequency of the device, and lowers the operating cost of the device. After the silt has undergone one filtration, it comes into contact with the movable screen plate, which also reduces the pressure on the movable screen plate during use.

[0019] The river silt rapid dewatering and solidification equipment provided by this utility model uses a second motor to drive a disc to rotate, which in turn causes the rotating wheel to roll over a baffle through a connecting rod. The baffle then causes the movable screen plate to shake with the assistance of the first and second elastic telescopic rods. This prevents small particles from clogging the holes on the movable screen plate during secondary filtration, while also increasing the speed of water separation from small particles and improving the efficiency of secondary filtration.

[0028] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0029] As described in the background art, the extrusion process places a significant burden on the filter screen, causing it to deform and thus reducing its filtration efficiency. This increases the frequency of filter screen replacement and consequently raises the operating cost of the device.

[0030] To solve this technical problem, this utility model provides a rapid dewatering and solidification device for river silt, which is applied to the rapid dewatering and solidification of river silt to reduce the burden on the filter screen.

[0031] For details, please refer to Figures 1-2 The aforementioned rapid dewatering and solidification equipment for river silt specifically includes:

[0032] The device includes a housing 1, a dewatering mechanism 4 on the top of the housing 1, a screening mechanism 5 inside the housing 1, a feed inlet 2 fixedly connected to the top of the housing 1, a discharge port on the outside of the housing 1, and a discharge outlet 3 fixedly connected to the inside of the housing 1.

[0033] The dehydration mechanism 4 includes a protective shell 6 fixedly connected to the top of the device housing 1, a first motor 7 fixedly connected to the top of the device housing 1, and a fixed screen plate 27 fixedly connected to the inside of the device housing 1.

[0034] The river silt rapid dewatering and solidification equipment provided by this utility model uses a first motor 7 to drive a bidirectional threaded rod 8 to rotate, which in turn drives two active clamping plates 10 to move closer together under the restriction of a fixed rod 9. With the assistance of a driven clamping plate 12, the silt on the fixed screen plate 27 is squeezed, and the water and some small particles in the silt are squeezed to the bottom of the fixed screen plate 27, thus achieving preliminary dewatering. This process reduces the pressure on the fixed screen plate 27, reduces the wear and tear on the fixed screen plate 27 during use, reduces the maintenance frequency of the device, and reduces the operating cost of the device. After the silt is filtered once, it comes into contact with the movable screen plate 14, which also reduces the pressure on the movable screen plate 14 during use.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] Example 1:

[0037] Please refer to Figures 1-3 A rapid dewatering and solidification device for river silt includes: a bidirectional threaded rod 8 rotatably connected to the output end of a first motor 7, the bidirectional threaded rod 8 being rotatably connected inside a protective shell 6, the protective shell 6 protecting the bidirectional threaded rod 8 to reduce silt clogging of the threads and ensure smooth operation of the device, and a fixing rod 9 being fixedly connected inside the protective shell 6.

[0038] The external thread of the bidirectional threaded rod 8 is connected to an active clamping plate 10. The active clamping plate 10 is slidably connected to the outside of the fixed rod 9. The external rotatable connection of the active clamping plate 10 is a first roller 11. The first roller 11 makes the active clamping plate 10 slide more smoothly relative to the device housing 1. The first roller 11 is rotatably connected to the inside of the device housing 1.

[0039] The device housing 1 has a driven clamping plate 12 slidably connected inside, and a second roller 13 is rotatably connected to the outside of the driven clamping plate 12. The second roller 13 is slidably connected inside the device housing 1. Adjacent active clamping plates 10 and driven clamping plates 12 and driven clamping plates 12 are respectively provided with extrusion blocks and grooves to prevent sludge from being squeezed out from above. During the extrusion process, water and some smaller particles will flow out through the gap between the extrusion blocks and grooves.

[0040] Through the above structural design, the sludge enters the outer shell 1 of the device through the feed inlet 2 and is located on the upper part of the fixed screen plate 27. The first motor 7 is started to drive the bidirectional threaded rod 8 to rotate, which in turn drives the two active clamping plates 10 to move closer to the middle under the restriction of the fixed rod 9. This squeezes the sludge in the middle and the driven clamping plate 12 together, squeezing out the water in the sludge between the active clamping plate 10 and the driven clamping plate 12. The water carries some small particles and flows downward through the fixed screen plate 27.

[0041] Example 2:

[0042] The rapid dewatering and solidification equipment for river silt provided in Example 1 has been further optimized, specifically, as follows: Figures 2-6 As shown, the screening mechanism 5 includes a movable screen plate 14 movably connected inside the device housing 1. A first elastic telescopic rod 15 is closely attached to the outside of the movable screen plate 14. One end of the first elastic telescopic rod 15 away from the movable screen plate 14 is fixedly connected to the inside of the device housing 1. A baffle 21 is fixedly connected to the bottom of the movable screen plate 14.

[0043] A receiving plate 16 is fixedly connected inside the outer casing 1 of the device. A second motor 17 is fixedly connected to the top of the receiving plate 16. A disc 18 is fixedly connected to the output end of the second motor 17. A connecting rod 19 is fixedly connected to the outside of the disc 18. A rotating wheel 20 is rotatably connected to the end of the connecting rod 19 away from the disc 18.

[0044] A locking rod 23 is slidably connected inside the device housing 1. A U-shaped plate 22 is movably connected inside the device housing 1. The locking rod 23 is movably connected inside the U-shaped plate 22. A fixing block 24 is fixedly connected to the outside of the locking rod 23. A return spring 25 is fixedly connected to the outside of the fixing block 24. The end of the return spring 25 away from the fixing block 24 is fixedly connected inside the device housing 1.

[0045] A second elastic telescopic rod 26 is fixedly connected inside the U-shaped plate 22, and the end of the second elastic telescopic rod 26 away from the U-shaped plate 22 is tightly attached to the outside of the movable screen plate 14.

[0046] Through the above structural design, the second motor 17 is started to drive the disc 18 to rotate, which in turn drives the connecting rod 19 to rotate around the central axis of the disc 18. When the connecting rod 19 passes the baffle 21, the corresponding rotating wheel 20 on the connecting rod 19 rotates and pushes the movable screen plate 14 to move. After the rotating wheel 20 leaves the baffle 21, the movable screen plate 14 returns to its original position with the assistance of the first elastic telescopic rod 15 and the second elastic telescopic rod 26. Under the continuous drive of the second motor 17, the movable screen plate 14 shakes, which in turn vibrates the material on the movable screen plate 14. The water filtered in the second stage falls into the bottom of the device housing 1 and is finally discharged through the discharge port 3. After the work is completed, the locking rod 23 can be pulled to squeeze the reset spring 25 by the fixing block 24. After reaching the appropriate position, the U-shaped plate 22 can be pulled out to clean the movable screen plate 14 and the inside of the device housing 1.
