Description

Technical Field

[0001] The utility model belongs to the technical field of sludge dehydration, in particular to a riverbed sludge dehydration device. Background Art

[0002] According to a published patent with the announcement number CN117003461 A, a riverbed sludge dewatering device includes a mounting frame, a water collecting trough for collecting water flow after sludge dewatering and a mud collecting trough for collecting mud cake after sludge dewatering, a centrifugal limiting shell, which is obliquely arranged on the mounting frame, and a drain pipe for discharging water flow after sludge dewatering is provided at the bottom of the centrifugal limiting shell. Through the mating connection of the feed assembly and the meshing of the connecting gear ring and the connecting gear, the centrifugal shaft is rotated while driving the blade shaft to rotate, which can reduce the water content in the sludge. However, there are still the following deficiencies:

[0003] After completion, the above equipment can reduce the water content in the silt and enhance the dehydration effect. When dehydrating the silt, the inner wall of the dehydration barrel will be adhered to a large amount of silt due to the large amount of squeezing force, causing the equipment to be blocked, resulting in the entire equipment being stuck and causing internal damage to the equipment. At the same time, after the water in the silt is separated, some broken silt will also be included. If it is not screened, it will be mixed again. Therefore, we proposed a riverbed silt dehydration device. Utility Model Content

[0004] The purpose of the utility model is to provide a riverbed silt dewatering device. Through the connecting block, the problem that the existing equipment will cause the silt that has been dehydrated into mud cakes to adhere to the inside of the equipment due to the large amount of squeezing force on the silt in the water pressure bucket during use, resulting in a large amount of accumulation of the equipment and causing internal damage to the equipment, and at the same time, the large amount of squeezing force on the silt will cause some silt to be squeezed out and re-mixed with the dewatered water due to the large amount of squeezing force on the silt.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is a riverbed sludge dewatering device, comprising a processing box, an inner wall of the processing box is provided with a sludge cavity, an inner wall of the processing box is provided with a clean water cavity, an outer wall of the processing box is fixedly connected to a vertical plate, an outer wall of the top of the vertical plate is fixedly connected to a motor, an outer wall of the processing box is fixedly connected to a plurality of connecting plates, an outer wall of the connecting plate is fixedly connected to a dewatering barrel, an inner wall of the dewatering barrel is provided with a plurality of mud outlets, and a bottom output end of the motor is fixedly connected to a rotating shaft.

[0007] Furthermore, the outer wall of the rotating shaft is fixedly connected to a plurality of connecting blocks, the outer wall of the connecting block is fixedly connected to a gear plate, the outer wall of the gear plate is rotatably connected to a plurality of material transport pipes, the material transport pipe at the upper end is fixedly connected to the motor, and the material transport pipe at the lower end is fixedly connected to the dewatering barrel.

[0008] Furthermore, the inner wall of the material transport pipe is fixedly connected to a lower hopper, the outer wall of the rotating shaft is fixedly connected to a second material transport pipe, the outer wall of the dewatering barrel is fixedly connected to several material distribution pipes, the outer wall of the material distribution pipe is rotatably connected to a second gear disc, and the second gear disc is engaged with the gear disc.

[0009] Furthermore, a water outlet cavity is provided on the bottom inner wall of the dewatering barrel, a plurality of material distribution blocks are fixedly connected to the inner wall of the material transport pipe, the material distribution blocks are fixedly connected to the material distribution pipe, and a connecting shaft is fixedly connected to the central axis of the outer wall of the second gear disc.

[0010] Furthermore, the outer wall of the connecting shaft is fixedly connected to a discharge hopper, the outer wall of the connecting shaft is fixedly connected to a plurality of connecting rings, the outer wall of the connecting ring is fixedly connected to a plurality of connecting plates, the outer wall of the connecting plate is rotatably connected to an extrusion roller, the inner wall of the mud outlet is fixedly connected to a water pressure bucket, the extrusion roller is fitted with the inner wall of the water pressure bucket, and the inner wall of the clean water chamber is provided with a plurality of slide grooves.

[0011] Furthermore, the inner wall of the slide is slidably connected to a slider, the outer wall of the slider is fixedly connected to a sieve plate, the outer wall of the slide is fixedly connected to a plurality of extrusion columns, the inner wall of the extrusion column is slidably connected to an I-shaped shaft, the outer wall of the I-shaped shaft is sleeved with a spring, and the outer wall of the processing box is fixedly connected to motor 2.

[0012] Furthermore, the bottom output end of the motor 2 is fixedly connected to a rotating roller, the outer wall of the rotating roller is fixedly connected to a top plate, and the inner wall of the processing box is fixedly connected to a water outlet pipe.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model is provided with a toothed disc on the connecting block. When the equipment needs to be used, the silt is discharged into the material transport pipe through the lower hopper. Then, the motor is started. When the motor is started, the rotating shaft starts to rotate, and then the multiple material transport pipes start to move, so that the silt continues to move forward. Then, the rotating shaft drives the multiple connecting blocks at the same time to move the toothed disc. When the toothed disc moves, the multiple toothed discs start to move together. Then, when the material transport pipe moves, the silt is separated into multiple material distribution pipes through multiple material distribution blocks, so that the silt attached to the water pressure barrel can be quickly cleaned up to prevent it from being stuck inside for a long time, resulting in a large amount of mud cake accumulation, which makes it difficult to transport the equipment and causes damage to the equipment.

[0015] 2. The utility model is provided with a rotating roller on the second motor. When the equipment is in use, the second motor is started and the rotating roller starts to rotate, and at the same time, the top plate starts to continuously lift the sieve plate. When the sieve plate is lifted, the slider slides in the chute, and at the same time, multiple I-shaped shafts are squeezed to slide into the extrusion column, and multiple springs are compressed at the same time. After the top plate does not contact the sieve plate, the multiple springs will quickly rebound the I-shaped shaft, causing the slider to drive the sieve plate to reset and vibrate, thereby achieving the separation of water and residual silt, and preventing the silt from being squeezed out during dehydration, causing the water and silt to mix with each other, making it difficult to reuse it later. Of course, any product implementing the utility model does not necessarily need to achieve all the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0033] A specific application of this embodiment is:

[0034] When the staff needs to use the equipment, the silt is discharged into the material transport pipe 111 through the lower hopper 112, and then the motor 104 is started. When the motor 104 is started, the rotating shaft 108 is driven to rotate, and then the multiple material transport pipes 113 are driven to move, so that the silt continues to move forward.
