Abstract
Description
Technical Field
[0001] This utility model relates to the field of sludge treatment technology, specifically to a sludge treatment device for lakes. Background Technology
[0002] Lakes accumulate silt due to water flow and long-term sediment buildup. This silt can easily clog waterways, necessitating the removal and treatment of the silt. Traditional silt dewatering processes include natural dewatering and drying, vacuum preloading, and geotextile bag methods. Natural dewatering utilizes sunlight and air convection to naturally dewater and dry the silt. Vacuum preloading involves covering the silt with a membrane and applying a vacuum. The geotextile bag method involves filling geotextile bags with high-moisture silt or slurry, using the bags' permeability to compact and promote dewatering. However, these methods are time-consuming, require significant space, and are inconvenient. Therefore, we propose a silt treatment device for lakes to address these issues. Utility Model Content

[0022] The technical solutions of the present utility model 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 utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Example
[0024] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown in the figure, an embodiment of this utility model discloses a sludge treatment device for lakes, including a support 1, four guide seats 2 fixed on the support 1, a treatment box 3 fixed between the four guide seats 2, and two sealed sliding shells 4 inside the treatment box 3. A filter plate 5 is fixed to one side wall of each shell 4, and a drain pipe 6 is fixedly connected to one side wall of each shell 4. A flexible hose is fixedly connected to each drain pipe 6. Under the action of the flexible hose, when the drain pipe 6 is connected and fixed to the pipe for collecting sludge water, the movement of the shell 4 is not interfered with. A double-sided guide seat 2 is rotatably connected between the two guide seats 2 via bearings. Two double-acting lead screws 7 are threaded to both ends of each other and have movable seats 8 that are adapted to their surface threads. The movable seats 8 are fixedly connected to the corresponding housings 4. Guide rails 9 are fixed to both side walls of the processing box 3. Two baffles 10 for sealing the bottom opening of the processing box 3 are slidably connected between the two guide rails 9. Mounting plates 12 are fixed to one side wall of each of the two guide seats 2. Two double-acting lead screws 13 are rotatably connected between the two mounting plates 12 through bearings. Movable plates 14 adapted to their surface threads are threaded to both ends of the double-acting lead screws 13. The movable plates 14 are respectively connected to the corresponding housings 4. The baffle 10 is fixedly connected, and the processing box 3 is equipped with a cleaning component 11 for cleaning the two filter plates 5. During the use of this lake sludge treatment device, the sludge can be sent into the processing box 3. Then, the motor is started to drive the two double-headed screws 7 to rotate. When the two double-headed screws 7 rotate, they will drive the moving seats 8 on both sides to move in opposite directions. At this time, the two housings 4 will move in opposite directions. After the housings 4 move, they will drive the filter plates 5 to move towards the middle position to squeeze the sludge. At this time, the water in the sludge will pass through the filter plates 5 and enter the interior of the housing 4. Then it can be discharged through the drain pipe 6. After dewatering... The sludge will remain inside the processing tank 3. The motor is started to drive the double-acting screw 13 to rotate. After the double-acting screw 13 rotates, it will drive the two moving plates 14 to move synchronously in opposite directions. After the moving plates 14 move, they will drive the baffles 10 to move. At this time, the two baffles 10 can release the obstruction of the dewatered sludge after moving in opposite directions. Then the sludge can be discharged into the processing tank 3. When discharging the sludge, the filter plates 5 on both sides can be reset. Then, under the action of the cleaning component 11, the filter plates 5 can be cleaned to prevent the mesh from becoming blocked and affecting the effect of subsequent squeezing and dewatering of the sludge.
[0025] like Figure 1 , Figure 3 and Figure 5As shown, in some embodiments, the cleaning assembly 11 includes a rotating shaft 1101 rotatably connected to the top of the processing box 3 via bearings. A gear 1102 is fixed to the surface of the rotating shaft 1101. Two racks 1103 are slidably connected to the top of the processing box 3. T-shaped guide strips 1107 are fixed to the bottom of each rack 1103. Two T-shaped guide grooves 1108, adapted to the T-shaped guide strips 1107, are provided on the top of the processing box 3 to limit and support the racks 1103, making them more stable when sliding on the top of the processing box 3. The racks 1103 are meshed with the gears 1102. U-shaped rods 1104 for reciprocating striking of the filter plate 5 are slidably passed through the side walls of the housing 4. The U-shaped rods 1104 are fixedly connected to corresponding racks 1103. Connecting pipes 1105 are provided inside each U-shaped rod 1104, with one end of each connecting pipe 1105 slidably passing through the racks 1103. The corresponding housing 4 extends into it and is connected to and fixed with a water spray plate 1106. When in use, after starting the forward and reverse motor, the rotating shaft 1101 can be driven to rotate forward and reverse. When the rotating shaft 1101 rotates forward and reverse, it can drive the gear 1102 to rotate forward and reverse. At this time, it can drive the two racks 1103 to move back and forth. After the racks 1103 move back and forth, they will drive the U-shaped rod 1104 to move back and forth. Therefore, the filter plate 5 can be vibrated and struck back and forth to avoid clogging. If the effect of cleaning the filter plate 5 by vibration is poor, the water supply pipe and the connecting pipe 1105 can be connected and fixed. Then the rinsing water can be sent to the interior of the water spray plate 1106 and sprayed out. At this time, the filter plate 5 can be rinsed while vibrating. A hose is connected and fixed at one end of the connecting pipe 1105. When one end is connected and fixed to the water supply pipe, the water spray plate 1106 will not interfere when it moves with the housing 4.
[0026] like Figure 3 As shown, in some embodiments, a sealing ring 17 that matches the shape of the filter plate 5 is fixed on the filter plate 5. The surface of the sealing ring 17 is in close contact with the inner wall of the treatment box 3, which can enhance the tightness of the filter plate 5 and the inner wall of the treatment box 3 after they are in contact, and prevent sewage from flowing out from the gap between them when squeezed.
[0027] like Figure 1 and Figure 3 As shown, in some embodiments, a feeding hopper 15 for guiding the discharged sludge is fixed on the support 1, and a feeding hopper 16 for guiding the fed sludge is provided above the feeding hopper 15. The feeding hopper 16 is connected and fixed to the processing box 3. The feeding hopper 16 facilitates the feeding of sludge into the processing box 3 for squeezing and dewatering, while the feeding hopper 15 can guide the sludge discharged after dewatering inside the processing box 3.
[0028] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
