Description

Technical Field

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

[0002] With the acceleration of urbanization and the increasing demand for water environment management, the treatment of river silt has become an important task. Currently, there are many problems in the dewatering and collection stages of river silt treatment. Traditional silt dewatering methods are inefficient; for example, natural sun-drying is greatly limited by weather and site conditions, has a long processing cycle, and cannot meet the needs of large-scale river dredging. Mechanical extrusion dewatering equipment is complex in structure, expensive, and its dewatering effect is unstable. Regarding silt collection, existing devices often cannot achieve integrated and efficient operation of dewatering and collection, resulting in a cumbersome silt treatment process and increased labor and time costs. Furthermore, some equipment does not adequately treat the silt during dewatering, and wastewater separation is incomplete, affecting the subsequent reuse and disposal of the silt. Therefore, there is an urgent need for a device that can quickly and efficiently dewater and collect river silt to improve the efficiency and quality of river silt treatment. Utility Model Content

[0003] This invention addresses the problems of low dewatering efficiency, inconvenient collection, and insufficient treatment of river silt in existing technologies by providing a rapid dewatering and collection device for river silt, thereby achieving rapid dewatering and efficient collection of river silt and improving the overall efficiency and quality of silt treatment.

[0004] The objective of this utility model is mainly achieved through the following solution:

[0005] A rapid dewatering and collection device for river silt includes a frame. A hollow dewatering tank is mounted on top of the frame. The dewatering tank is divided into a dewatering chamber and a collection chamber by a vertical partition. A dewatering cylinder is installed along the length of the dewatering chamber. Both ends of the dewatering cylinder are in contact with the dewatering tank and the vertical partition, respectively. A rotating shaft is rotatably connected inside the dewatering cylinder. The outer wall of the rotating shaft is equipped with helical blades. One end of the rotating shaft passes through the dewatering cylinder and the dewatering tank and is connected to a drive assembly on the frame. The other end of the rotating shaft passes through the dewatering cylinder, the vertical partition, and the dewatering tank and is rotatably connected to a bearing on the frame. The drive assembly can drive the rotating shaft to rotate. A discharge port for the dewatered sludge to pass through is opened in the middle of the vertical partition. A baffle for blocking the discharge port is slidably connected to the side wall of the rotating shaft in the collection chamber, and the baffle moves along the length of the rotating shaft via a telescopic assembly.

[0006] Preferably, a feed hopper is provided above the end of the dehydration cylinder away from the collection chamber, and the top of the feed hopper passes through the dehydration tank.

[0007] Preferably, the outer wall of the dehydration cylinder is equipped with a plurality of reinforcing plates along its length, the periphery of which contacts the inner wall of the dehydration tank, and a notch for wastewater to pass through is provided at the center of the bottom of the reinforcing plate.

[0008] Preferably, the multiple reinforcing plates are connected by connecting rods.

[0009] Preferably, the bottom of the dehydration chamber is provided with a water outlet, and a water collection tank is provided below the frame at a position corresponding to the water outlet.

[0010] Preferably, the diameter of the dewatering cylinder gradually decreases along the sludge conveying direction, and the helical radius of the spiral blades also gradually decreases along the sludge conveying direction.

[0011] Preferably, the dewatering cylinder includes an upper cylinder and a lower cylinder, both of which are semi-circular in structure, and the side wall of the lower cylinder is provided with several filter holes.

[0012] Preferably, the telescopic assembly is provided in two sets, symmetrically arranged on both sides of the rotating shaft. The fixed end of the telescopic assembly is installed on the inner wall of the dehydration tank, and the telescopic end of the telescopic assembly is connected to the baffle.

[0013] Preferably, the bottom of the collection chamber is provided with a mud outlet.

[0014] In summary, compared with the prior art, the present invention has the following beneficial technical effects:

[0015] (1) This utility model gradually squeezes the sludge by gradually reducing the diameter of the dewatering cylinder and the spiral radius of the spiral blade, which greatly improves the dewatering efficiency. Compared with the traditional dewatering method, it can achieve efficient dewatering of sludge in a shorter time. At the same time, the telescopic components and baffles block the discharge port, ensuring that the sludge has enough time and space to squeeze and dewater in the dewatering cylinder, further improving the dewatering effect.

[0016] (2) This utility model integrates the functions of sludge dewatering and collection into the same device. Through the coordinated work of the drive component and the telescopic component, the automation and integration of dewatering and collection are realized, reducing manual intervention, reducing labor intensity and cost, and improving overall processing efficiency.

[0017] (3) The present invention provides a reinforcing plate and a connecting rod on the outside of the dehydration cylinder, which enhances the structural strength and stability of the device, ensures that the device maintains a good working condition during long-term operation, and extends the service life of the equipment;

[0018] (4) The opening and closing of the control baffle of the telescopic component in this utility model can flexibly control the time and amount of sludge entering the collection chamber according to actual needs, which facilitates the operation and management of the equipment. Whether it is the need for different processing volume or the treatment of sludge of different properties, it can be effectively adjusted by controlling the telescopic component and the baffle.

Detailed Implementation

[0025] The technical solution of this utility model will be further described in detail below through specific embodiments and in conjunction with the accompanying drawings. It should be understood that the implementation of this utility model is not limited to the following embodiments, and any modifications and / or alterations made to this utility model will fall within the protection scope of this utility model.

[0026] Example 1:

[0027] like Figure 1 , 2As shown in Figure 3, this utility model discloses a technical solution: a rapid dewatering and collection device for river silt, comprising a frame 1. A hollow dewatering tank 2 is bolted to the top of the frame 1. The upper front of the dewatering tank 2 has an opening for easy observation of the dewatering process. The interior of the dewatering tank 2 is divided into a dewatering chamber 4 on the right and a collection chamber 5 on the left by a vertical partition 3. The vertical partition 3 is welded or bolted to the inner wall of the dewatering tank 2. A dewatering cylinder 6 is installed along the length of the dewatering chamber 4, with both ends of the dewatering cylinder 6 connected to the inner side of the dewatering tank 2. The side walls of the wall and vertical partition 3 are welded together, and a rotating shaft 7 is coaxially rotatably connected inside the dehydration cylinder 6. Spiral blades 8 are welded to the outer side wall of the rotating shaft 7 located in the dehydration chamber 4. The right end of the rotating shaft 7 passes through the dehydration cylinder 6 and the dehydration box 2 and is connected to the drive assembly 9 on the frame 1. The drive assembly 9 uses a drive motor, and the rotating shaft 7 is fixedly connected to the output end of the drive motor. The left end of the rotating shaft 7 passes through the dehydration cylinder 6, the vertical partition 3, and the dehydration box 2 and is rotatably connected to the bearing 10 on the frame 1. The drive assembly 9 can drive the rotating shaft 7 to rotate. Figure 5 As shown, the vertical partition 3 has a discharge port 11 in the middle for the sludge to pass through after dewatering. The discharge port 11 is coaxially arranged with the dewatering cylinder 6. The side wall of the rotating shaft 7 in the collection chamber 5 is slidably connected to a baffle 12 for blocking the discharge port 11, and the baffle 12 is driven to move left and right along the length direction of the rotating shaft 7 by the telescopic component 13.

[0028] Example 2:

[0029] like Figure 1 , 4 As shown, this utility model discloses another technical solution: a rapid dewatering and collection device for river silt. The difference from embodiment 1 is that a feeding hopper 14 communicating with the inside of the dewatering cylinder 6 is welded to the upper right end of the cylinder. The top of the feeding hopper 14 passes through the dewatering box 2, which facilitates the input of silt.

[0030] Specifically, multiple reinforcing plates 15 are welded or bolted to the outer wall of the dewatering cylinder 6 along its length. The reinforcing plates 15 are welded and fixed to the inner wall of the dewatering tank 2 around their perimeter. A notch 16 for sewage to pass through is provided at the bottom center of the reinforcing plate 15. The multiple reinforcing plates 15 are connected by connecting rods 17, and the connecting rods 17 are bolted to the reinforcing plates 15 to enhance the stability and structural strength of the dewatering cylinder 6, while facilitating sewage discharge.

[0031] Specifically, the bottom of the dehydration chamber 4 is provided with an outlet 18, and a water collection tank 19 is provided below the frame 1 at a position corresponding to the outlet 18, for collecting the wastewater generated during the dehydration process.

[0032] Example 3:

[0033] like Figure 1 , 4As shown, this utility model discloses another technical solution: a rapid dewatering and collection device for river silt. The difference from embodiment 1 is that the diameter of the dewatering cylinder 6 gradually decreases along the sludge conveying direction, and the spiral radius of the spiral blade 8 also gradually decreases along the sludge conveying direction, which can more effectively squeeze and dewater the silt.

[0034] Specifically, the dewatering cylinder 6 includes an upper cylinder 20 and a lower cylinder 21. Both the upper cylinder 20 and the lower cylinder 21 have a semi-circular structure. The upper cylinder 20 and the lower cylinder 21 are connected by bolts, and the side wall of the lower cylinder 21 is provided with several filter holes 22 to facilitate the filtration and discharge of wastewater.

[0035] Example 4:

[0036] like Figure 1 , 4 As shown, this utility model discloses another technical solution, a rapid dewatering and collection device for river silt. The difference from embodiment 1 is that the telescopic component 13 is provided in two sets and is symmetrically arranged on the front and rear sides of the rotating shaft 7. The fixed end of the telescopic component 13 is installed on the left inner wall of the dewatering tank 2 by bolts. The telescopic end of the telescopic component 13 is connected to the baffle 12 by bolts to ensure that the baffle 12 stably blocks and opens the discharge port 11. The telescopic component 13 adopts a push rod motor.

[0037] Specifically, the bottom of the collection chamber 5 is provided with a mud outlet 23 for collecting dewatered sludge.

[0038] It should be noted that both the drive component 9 and the telescopic component 13 are commercially available. Their specific structures and control methods are existing technologies and are not within the scope of protection of this application. Those skilled in the art can deduce them through conventional technical means, so they will not be described in detail here.

[0039] The rapid dewatering and collection device for river silt provided by this utility model, when the river silt enters the dewatering cylinder 6 from the feed hopper 14, the drive component 9 drives the rotating shaft 7 to rotate, and the spiral blades 8 on the rotating shaft 7 push the silt to move inside the dewatering cylinder 6. At the beginning of the dewatering stage, the telescopic component 13 is in an extended state, driving the baffle 12 to move along the rotating shaft 7, completely blocking the discharge port 11 on the vertical partition 3. At this time, since the discharge port 11 is closed, as the spiral blades 8 continuously push the silt to move towards the collection chamber 5, and the diameter of the dewatering cylinder 6 gradually decreases along the sludge conveying direction, the spiral radius of the spiral blades 8 also gradually decreases. The silt is subjected to increasingly greater compression in the dewatering cylinder 6. Under the strong compression force, the water in the silt is discharged through the filter holes 22 on the side wall of the lower cylinder 21, enters the dewatering tank 2, and flows into the collection tank 19 through the outlet 18, realizing the compression dewatering of the silt.

[0040] After the sludge is squeezed and dewatered inside the dewatering cylinder 6, the telescopic component 13 retracts, causing the baffle 12 to move in the opposite direction along the rotating shaft 7, opening the discharge port 11. At this time, the spiral blades 8 on the rotating shaft 7 continue to rotate, pushing the dewatered sludge through the opened discharge port 11 into the collection chamber 5. Under the continuous pushing of the spiral blades 8, the sludge entering the collection chamber 5 is finally discharged from the sludge outlet 23 at the bottom of the collection chamber 5, completing the sludge collection process. Through the cooperation of the telescopic component 13 and the baffle 12, flexible control of the discharge port 11 is achieved, ensuring that the sludge is fully squeezed and dewatered inside the dewatering cylinder 6 and enters the collection chamber 5 for collection in an orderly manner.

[0041] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
