All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
In the examples, see fig. 1 to 9 in detail.
As shown in fig. 1 to 4, the present application provides a river bottom sludge dewatering device comprising:
the device comprises a mounting frame body 1, wherein a water receiving tank 11 for collecting water flow after sludge dehydration and a sludge receiving tank 12 for collecting sludge cakes after sludge dehydration are arranged on the mounting frame body 1;
the centrifugal limit shell 2 is obliquely arranged on the mounting frame body 1, and a drain pipe 21 for draining water flow after sludge dehydration is arranged at the bottom of the centrifugal limit shell 2;
the centrifugal driving assembly 4 is arranged on the centrifugal limiting shell 2 and is used for centrifugal dehydration treatment of river bottom sludge;
a feeding assembly 3 arranged on the mounting frame body 1 for feeding sludge of the centrifugal driving assembly 4;
the filter pressing pushing-out assembly 5 is arranged on the centrifugal driving assembly 4 and connected with the feeding assembly 3, and is used for carrying out filter pressing treatment on the mud cake after centrifugal dehydration and pushing the mud cake after filter pressing into the mud collecting groove 12 while the centrifugal driving assembly 4 is running.
In specific implementation, the synchronous driving of the centrifugal driving assembly 4 and the filter pressing pushing assembly 5 can be used for dewatering after the sludge enters the device through the feeding assembly 3, the water flow after sludge dewatering enters the water receiving tank 11 through the water discharging pipe 21 in the centrifugal limiting shell 2 for collecting sludge, and the sludge cake after sludge dewatering is discharged from the centrifugal limiting shell 2 through the filter pressing pushing assembly 5 in combination with gravity and falls into the sludge receiving tank 12 for collecting.
As shown in fig. 4, 6 and 7, the centrifugal driving assembly 4 includes a first centrifugal mounting seat 43 and a second centrifugal mounting seat 44 which are rotatably disposed at two ends of the centrifugal limit housing 2, a plurality of sets of centrifugal sleeves 45 fixedly penetrating through the first centrifugal mounting seat 43 and the second centrifugal mounting seat 44 and arranged in parallel, a plurality of drainage holes 46 arranged on the centrifugal sleeves 45, a centrifugal rotating shaft 42 fixedly penetrating through the middle parts of the first centrifugal mounting seat 43 and the second centrifugal mounting seat 44, and a driving member 41 arranged at one end of the centrifugal rotating shaft 42 and used for driving the centrifugal rotating shaft 42 to rotate.
Specifically, the driving piece 41 controls the rotation of the centrifugal rotating shaft 42 to drive the first centrifugal installation seat 43 and the second centrifugal installation seat 44 to rotate, and because the centrifugal sleeve 45 is fixedly clamped on the first centrifugal installation seat 43 and the second centrifugal installation seat 44, when the centrifugal rotating shaft 42 rotates, the centrifugal sleeve 45 can also rotate centrifugally by taking the centrifugal rotating shaft 42 as the rotating shaft to finish the dehydration operation, compared with the traditional spiral dehydration centrifugal machine, the spiral dehydration centrifugal machine has better centrifugal dehydration effect, consumes less energy under the same dehydration effect, saves more resources, and greatly reduces the running cost.
In practice, the sludge is fed into the centrifugal sleeve 45, the centrifugal rotating shaft 42 is driven to rotate, two groups of centrifugal installation seats are matched to effectively carry out centrifugal dewatering operation on the sludge in the centrifugal sleeve 45, and the dewatered water can be quickly discharged through the drain pipe 21, so that poor dewatering effect caused by continuous contact of water flow with the sludge in the dewatering process is avoided, and the centrifugal dewatering efficiency of the sludge is improved
It should be noted that the driving member 41 is fixed, and the centrifugal shaft 42 is only mounted on the rotating driving shaft of the driving member 41, where the driving member 41 may directly use a servo motor as shown in the drawings, or may use other motor structures or other mechanical structures with a rotating driving effect.
In addition, the centrifugal driving assembly 4 further comprises a limiting ring block 47 which is arranged on the first centrifugal mounting seat 43 and the second centrifugal mounting seat 44 and used for limiting the rotation of the first centrifugal mounting seat 43 and the second centrifugal mounting seat 44 on the centrifugal limiting shell 2, and when the first centrifugal mounting seat 43 and the second centrifugal mounting seat 44 rotate, the limiting ring block 47 can also play a role in supporting the first centrifugal mounting seat 43 and the second centrifugal mounting seat 44 and improving the integral strength of the device.
It should be noted that, the stop collar block 47 may be disposed to rotate outside the centrifugal stop housing 2 as shown in the drawings, or may be disposed to rotate on the inner wall of the centrifugal stop housing 2, so that it is required to ensure the connection waterproof property between the centrifugal stop housing 2 and the two sets of centrifugal mounting seats.
As shown in fig. 3, 5, 7 and 8, the feeding assembly 3 includes a distributing pipe 33 disposed on a first centrifugal mounting seat 43 and located outside a centrifugal rotating shaft 42, a plurality of distributing housings 35 disposed on the distributing pipe 33 and in one-to-one communication with the inside of a centrifugal sleeve 45, a mounting pipe 32 disposed on the mounting frame body 1 and sleeved outside the centrifugal rotating shaft 42 for communicating the distributing pipe 33, and a feeding funnel 31 disposed on the mounting pipe 32 for feeding sludge, wherein the mounting pipe 32 and the distributing pipe 33 are connected by a limiting assembly 34, and a driving member 41 is mounted on the mounting pipe 32.
In specific implementation, a plurality of distributing shells 35 communicated to the inside of the centrifugal sleeve 45 are located outside the distributing pipelines 33 and are uniformly distributed in an annular shape, the annular center is the position of the distributing pipelines 33, at the moment, the centrifugal rotary shaft 42 is utilized to control two groups of centrifugal installation seats to rotate and simultaneously drive the distributing pipelines 33 and the distributing shells 35 to synchronously rotate, and as the powder pipelines are limited to rotate on the installation pipelines 32 through the limiting assemblies 34, after the sludge sequentially passes through the feeding hopper 31 and the installation pipelines 32 to enter the distributing pipelines 33, the sludge can be uniformly fed into the distributing shells 35 by utilizing centrifugal force and gravity and then enter the centrifugal sleeve 45 to carry out centrifugal dehydration operation, so that the normal centrifugal dehydration feeding of the sludge is ensured.
As shown in fig. 9, the limiting assembly 34 includes a rotating ring block 341 disposed outside one end of the mounting pipe 32, a plurality of clamping blocks 342 disposed at one end of the distributing pipe 33, a clamping groove 343 disposed on the clamping blocks 342 for clamping the rotating ring block 341 for limiting rotation, a ball groove 344 disposed in the clamping groove 343, and a connecting ball 345 disposed in the ball groove 344 for rolling on the rotating ring block 341.
When the centrifugal mounting seat drives the material distributing pipe 33 and the material distributing casing 35 to rotate synchronously, since the mounting pipe 32 passes through the fixing position of the mounting frame body 1, when the material distributing pipe 33 rotates at one end of the mounting pipe 32, the rotation position of the material distributing pipe 33 can be limited by utilizing the clamping grooves 343 and the clamping of the rotating ring blocks 341, at the moment, the connecting balls 345 can ensure that the friction force between the connecting balls 345 and the rotating ring blocks 341 is greatly reduced when the material distributing pipe 33 rotates, so that the rotation effect of the material distributing pipe 33 is improved, at the moment, the attention is paid that the rotating ring blocks 341 are clamped in the clamping grooves 343, but gaps still exist between the rotating ring blocks 341 and the inner walls of the clamping grooves 343, and the rotating ring blocks 341 only contact with the connecting balls 345 to ensure the normal rotation of the rotating ring blocks 341.
As shown in fig. 4 and 5, the filter-press pushing assembly 5 includes a vane rotary shaft 52 which rotates through the distributing housing 35 and is located in the centrifugal sleeve 45, a spiral vane 51 which is provided on the vane rotary shaft 52 and rotates in the centrifugal sleeve 45, a limiting frame 53 which is provided on the centrifugal sleeve 45 for limiting the rotation of the vane rotary shaft 52, a connection gear 54 which is provided at one end of the vane rotary shaft 52, and a connection toothed ring 55 which is provided on the mounting pipe 32 for engagement connection with the connection gear 54.
Because the connection toothed ring 55 is cooperatively installed on the installation pipe 32, and because the connection toothed ring 55 is fixed by the position and posture of the connection limiter of the installation pipe 32, when the driving piece 41 controls the rotation of the centrifugal rotating shaft 42, the rotation of the blade rotating shaft 52 is driven by the meshing centrifugal rotating shaft 42 of the connection toothed ring 55 and the connection gear 54, so that the centrifugal driving assembly 4 and the filter pressing pushing assembly 5 which are connected with each other are synchronously driven, namely: the two groups of centrifugal installation seats are controlled to drive the centrifugal sleeve to rotate for dehydration, and the spiral blades 51 are driven to rotate inside the centrifugal sleeve to push out mud cakes after mud dehydration by matching with gravity.
At this time, the spiral pitch of the spiral vane 51 gradually narrows along the direction from the first centrifugal mounting seat 43 to the second centrifugal mounting seat 44, so that in the process of centrifugal dewatering of the sludge, the spiral vane 51 can provide sludge discharge thrust for the sludge by matching with gravity, and meanwhile, the gradually narrowing pitch can be utilized to perform certain extrusion on the centrifugally dewatered sludge to match with the water filtering holes 46 of the centrifugal sleeve so as to complete filter pressing treatment of the sludge, thereby achieving the filter pressing effect in sludge conveying, reducing the water content of the sludge after the centrifugal dewatering operation, ensuring the dewatering efficiency of the sludge and improving the integral dewatering effect of the sludge.
In addition, in one embodiment, as shown in fig. 8, the feeding assembly 3 further includes a rotation limiter 36 provided on the distributing casing 35 for rotating the vane shaft 52 on the distributing casing 35.
Specifically, the rotation limiting part 36 can limit the rotation of the vane rotating shaft 52 to pass through the material distributing casing 35 and enter the centrifugal sleeve to drive the threaded vane to rotate, so that the integral normal operation of the device is ensured, therefore, the rotation limiting part 36 can be set into a ball bearing to improve the rotation effect of the vane rotating shaft 52, and a limiting sleeve externally stuck with a waterproof strip can be adopted to improve the airtight waterproof performance in the centrifugal limiting casing 2 of the device, so that water is prevented from leaking from the limiting sleeve in the centrifugal process.
In addition, in one embodiment, as shown in fig. 3, the filter pushing assembly 5 further includes a partition 56 disposed on the first centrifugal mounting base 43 for partitioning the overall position of the plurality of connecting gears 54 when they rotate.
In particular, the partition 56 mainly separates to ensure normal rotation of different connecting gears 54, so that the partition 56 can only adopt a partition plate as shown in the drawings, and can also be set to limit the rotation position of the connecting gears 54 by a shell structure, thereby improving the stability of rotation of the connecting gears 54 and ensuring the overall strength of the device during operation.
