Description

Technical Field

[0001] The utility model belongs to the technical field of sludge treatment and relates to a sludge cyclone carbon release treatment device. Background Art

[0002] Domestic sewage and agricultural sewage usually contain a large amount of sludge rich in organic matter. In order to avoid polluting the ecological environment by directly discharging sludge, and at the same time to recover useful elements such as carbon contained in the organic matter in the sludge, it is necessary to release carbon from the sludge before discharging it.

[0003] In order to ensure that the sludge can fully react with the carbon-releasing agent and microorganisms during the carbon-releasing treatment process, it is necessary to crush the organic matter in the sludge. In the existing sludge treatment technology, the organic matter in the sludge is usually crushed by setting up corresponding extrusion and stirring mechanical devices, physical heating devices, and ultrasonic crushing devices. However, the above-mentioned sludge crushing devices all have their own defects, such as the low efficiency of the traditional extrusion and stirring mechanical device in crushing the organic matter in the sludge, the high energy consumption of the physical heating device, and the high cost of using the ultrasonic crushing device.

[0004] Therefore, in view of the defects of the above-mentioned existing sludge crushing treatment technology, the utility model discloses a sludge cyclone carbon release treatment device. Utility Model Content

[0005] The utility model aims to provide a sludge cyclone carbon release treatment device, which fully utilizes the shear force generated during the sludge cyclone to perform secondary shear crushing on the organic cells in the sludge, and at the same time separates the water in the sludge through the centrifugal force generated by the cyclone to reduce the water content of the sludge, thereby achieving sludge reduction treatment.

[0008] The sewage containing sludge enters the inner vortex tank through the inlet at the top of the inner vortex tank, and the inner vortex breaking device inside the inner vortex tank rotates in a first direction to apply a vortex shear force in a first direction to the flocs in the sludge, thereby shearing and breaking the flocs in the sludge so that the organic cells in the sludge are fully broken, ensuring that the sludge can fully react and fully release carbon in the subsequent carbon release treatment process. The sludge broken by the inner vortex breaking device is transported to the outer vortex tank through the pipeline at the outlet of the bottom of the inner vortex tank, and the outer vortex breaking device in the outer vortex tank causes the sludge to swirl in a second direction opposite to the first direction to further break the organic cells in the sludge, and at the same time, the sewage and the sludge are separated by the centrifugal force generated by the vortex to reduce the water content of the sludge. Then the sludge broken by the secondary vortex is discharged through the mud discharge port at the bottom of the outer vortex tank and transported to the subsequent carbon release treatment device for carbon release treatment.

[0009] In order to better realize the utility model, further, the internal vortex flow breaking device includes a rotating shaft, an internal spiral flow channel, and an internal rotating motor. The internal vortex flow tank is coaxially rotated with a rotating shaft, the outer spiral of the rotating shaft is spirally provided with an internal spiral flow channel, one end of the rotating shaft is transmission-connected to the output shaft of the internal rotating motor, and the outlet of the internal spiral flow channel is correspondingly connected to the inlet of the external vortex flow breaking device.

[0014] In order to better implement the present invention, further, the spiral radius of the outer spiral flow channel gradually decreases from top to bottom.

[0015] Compared with the prior art, the utility model has the following advantages and beneficial effects:

[0016] The utility model arranges an inner cyclone breaking device rotating along a first direction inside an inner cyclone tank, and performs a cyclone breaking on the sludge entering the inner cyclone tank through the inner cyclone breaking device, so as to fully break the organic cells in the sludge; then the sludge after the primary breaking is transported to an outer cyclone tank, and the outer cyclone breaking device inside the outer cyclone tank drives the sludge to swirl along a second direction opposite to the first direction, and the shear force generated by the directional swirl is used to perform a secondary breaking on the organic cells in the sludge, so that the carbon and water in the organic cells are fully released, and at the same time, the sludge is separated from the water by the centrifugal force generated by the swirl to reduce the water content of the sludge, so as to achieve the reduction treatment of the sludge.

[0029] Embodiment 1:

[0030] A sludge cyclone carbon release treatment device according to this embodiment, such as Figure 1-Figure 5 As shown, it includes a vortex tank body 1, which includes an inner vortex tank 11 and an outer vortex tank 12 arranged outside the inner vortex tank 11, the inner vortex tank 11 is provided with an inner vortex breaking device 2 for rotation, the outer vortex tank 12 is provided with an outer vortex breaking device 3, and the vortex direction of the inner vortex breaking device 2 is opposite to that of the outer vortex breaking device 3; the outlet of the inner vortex breaking device 2 is connected with the inlet of the outer vortex breaking device 3, and the outlet of the outer vortex breaking device 3 is provided with a liquid phase port and a sludge port.

[0031] The inner swirl tank 11 is coaxially arranged inside the outer swirl tank 12, and an inner swirl tank end cover is arranged on the top of the inner swirl tank 11, and a water inlet pipe is arranged on the inner swirl tank end cover, and the water inlet pipe is used to introduce water-containing sludge into the inner swirl tank 11. The inner swirl tank 11 is provided with an inner swirl breaking device 2 that rotates along a first direction. After the water-containing sludge enters the inner swirl tank 11, it is rotated along the first direction by the inner swirl breaking device 2, so that the water-containing sludge swirls along the first direction, and the organic cells in the water-containing sludge are broken once by the shear force generated by the swirl.

[0032] The water-containing sludge that has been crushed once is transported to the inlet at the top of the outer vortex tank 12 through the return pipe at the outlet at the bottom of the inner vortex tank 11, and a return pump is provided on the return pipe to provide power for conveying sludge. After the water-containing sludge enters the interior of the outer vortex tank 12, the outer vortex cracking device 3 inside the outer vortex tank 12 is rotated in a second direction opposite to the first direction, so that the water-containing sludge is swirled along the second direction, and then the shear force generated by the vortex is used to break the organic cells in the water-containing sludge for a secondary time. And the reflux pump is pressurized so that the water-containing sludge enters the outer vortex tank 12 at a faster flow rate for swirling, and the sufficient centrifugal force generated by the vortex separates the sludge from the water, thereby reducing the water content of the sludge. By dehydrating the sludge and breaking the secondary organic cells, it is ensured that the organic matter in the sludge is fully released to fully carry out the subsequent carbon release treatment.

[0033] Embodiment 2:

[0034] The sludge cyclone carbon release treatment device of this embodiment is improved on the basis of embodiment 1, such as Figure 4 and Figure 6 As shown, the inner vortex flow breaking device 2 includes a rotating shaft 21, an inner spiral flow channel 22, and an inner rotating motor 23. The inner vortex flow tank 11 is coaxially provided with a rotating shaft 21, and the outer side of the rotating shaft 21 is spirally provided with an inner spiral flow channel 22. One end of the rotating shaft 21 is drivingly connected to the output shaft of the inner rotating motor 23, and the outlet of the inner spiral flow channel 22 is connected to the inlet of the outer vortex flow breaking device 3.

[0035] The inner rotation motor 23 is arranged at the top of the inner vortex tank 11, and the output shaft of the inner rotation motor 23 is connected to the top of the rotating shaft 21 extending into the inner vortex tank 11. The outer side of the rotating shaft 21 is spirally provided with an inner spiral flow channel 22 along the first direction, and the rotating shaft 21 is driven to rotate by the inner rotation motor 23, thereby driving the inner spiral flow channel 22 to rotate along the first direction, so that the sludge entering the inner vortex tank 11 is fully swirled along the first direction, and the organic cells in the sludge are broken by the shear force generated by the swirling flow.

[0036] Furthermore, crushing grids 24 are evenly arranged along the circumferential direction between the inner spiral flow channel 22 and the inner wall of the inner vortex tank 11. The crushing grids 24 are provided with a fine mesh structure. When the sludge vortexes along the first direction, it will also pass through the crushing grids 24. The large flocs in the sludge are crushed by the crushing grids 24, thereby improving the vortex crushing effect of the organic cells in the sludge.

[0037] Furthermore, the spiral radius of the inner spiral flow channel 22 gradually decreases from top to bottom. As the spiral radius of the inner spiral flow channel 22 changes, the shear force to which the sludge is subjected when it swirls along the inner spiral flow channel 22 changes. The changing shear force can further ensure that the organic cells in the sludge are fully broken.

[0038] The other parts of this embodiment are the same as those of Embodiment 1, and thus will not be described in detail.

[0039] Embodiment 3:

[0040] A sludge cyclone carbon release treatment device in this embodiment is improved on the basis of embodiment 1 or 2, such as Figure 5 and Figure 7 As shown, the external vortex flow breaking device 3 includes a rotating gear 31, a rotating ring gear 32, an external spiral flow channel 33, and an external rotating motor 34. The external spiral flow channel 33 is coaxially rotatably arranged inside the external vortex tank 12, and a rotating ring gear 32 is arranged on the top outer side of the external spiral flow channel 33; a rotating gear 31 is arranged on the output shaft of the external rotating motor 34, and the rotating gear 31 is meshed with the rotating ring gear 32.

[0041] The outer swirl pot 12 is provided with a support pot outside, a first bearing is provided between the top inner wall of the support pot and the top outer wall of the outer swirl pot 12, and a second bearing is provided between the bottom inner wall of the support pot and the bottom outer wall of the outer swirl pot 12, so that the outer swirl pot 12 can rotate relative to the support pot. A rotating gear ring 32 is fixedly installed on the top inner wall of the outer swirl pot 12, and an inner meshing tooth is provided on the inner ring surface of the rotating gear ring 32. The top of the support pot is buckled with a top cover for shielding the outer swirl pot 12 and the inner swirl pot 11, and an outer rotating motor 34 is installed on the top of the top cover, and the output shaft of the outer rotating motor 34 extends to the inside of the outer swirl pot 12 through the through hole on the top cover, and a rotating gear 31 is mounted on the output shaft, and the rotating gear 31 is meshed with the inner meshing tooth of the rotating gear ring 32. The rotating gear 31 is driven to rotate by the outer rotating motor 34, and then the outer swirl pot 12 is driven to rotate along the second direction by the meshing structure of the rotating gear 31 and the rotating gear ring 32.

[0042] The interior of the outer vortex tank 12 is provided with an outer spiral flow channel 33 extending spirally in the second direction. With the rotation of the outer vortex tank 12, the sludge entering the outer vortex tank 12 can be fully vortexed in the second direction, and the organic cells in the sludge are secondary broken by the shear force generated by the vortex. At the same time, the sludge is separated from the water by the centrifugal force generated by the vortex to reduce the water content of the sludge and achieve sludge reduction treatment.

[0043] Furthermore, a plurality of cutting convex contacts are arranged on the swirling surface of the outer spiral flow channel 33 along the spiral direction. When the sludge swirls along the outer spiral flow channel 33, it collides with the cutting convex contacts, and the large-size flocs in the sludge are broken up and crushed by the cutting convex contacts.

[0044] Furthermore, the spiral radius of the outer spiral flow channel 33 gradually decreases from top to bottom. As the spiral radius of the outer spiral flow channel 33 changes, the shear force to which the sludge is subjected when it swirls along the outer spiral flow channel 33 changes. The changing shear force can further ensure that the organic cells in the sludge are fully broken.

[0045] The other parts of this embodiment are the same as those of Embodiment 1 or 2, and thus will not be described in detail.

[0046] The above are only preferred embodiments of the present invention and are not intended to limit the present invention in any form. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention fall within the protection scope of the present invention.
