Description

Technical Field

[0001] The present invention belongs to the technical field of sludge treatment, and particularly relates to an ultrasonic sludge digestion device capable of continuous treatment and a treatment method thereof. Background Art

[0002] An ultrasonic sludge digestion device is a device that uses ultrasonic technology to treat and degrade sludge. Through the high-frequency vibration waves generated by ultrasonic waves, energy is transmitted to the substances in the sludge, generating a cavitation effect (rapid expansion and contraction of bubbles), thereby destroying the cell structure in the sludge, promoting the decomposition of organic matter, and improving the biodegradability of the sludge.

[0003] In the existing ultrasonic sludge digestion devices, during use, sludge is usually put into the reaction chamber, and the filled sludge is ultrasonically treated with the built-in ultrasonic transducer, and the organic matter in the sludge is degraded and the cells are destroyed through the cavitation effect of ultrasonic waves. However, in the actual treatment process, in order to improve the treatment efficiency, the amount of filled sludge in the reaction chamber is large, the installation position of the ultrasonic transducer in the sludge is fixed, and the sound wave direction is limited. The treatment uniformity of the sludge in the reaction chamber is relatively low, resulting in uncompletely digested components in the finally discharged sludge. Moreover, under the requirement of further improving the treatment efficiency, continuous feeding is often required. However, sludge digestion takes time. It is difficult to achieve quick control for both continuous feeding and stable-time ultrasonic treatment. Often, multiple sets of control devices need to be added for multiple coordinated control operations, resulting in high electrical control costs, complex device structures, and poor comprehensive treatment effects.

[0016] A treatment method for an ultrasonic sludge digestion device capable of continuous treatment includes the following treatment steps:

[0017] First step: Input the sludge to be treated into the interior of the treatment outer cylinder along the inlet pipe, and start the driving assembly. The driving assembly drives the rotating treatment assembly engaged therewith to rotate, so that the rotating shaft drives the treatment inner cylinder to rotate.

[0018] Second step: When the treatment cavity on the outer side of the treatment inner cylinder rotates to the vertical state, the sludge fed along the inlet pipe is quickly filled into the treatment cavity. At the same time, start the ultrasonic composite treatment assembly, start the ultrasonic transducer, and act on the sludge, so that the sludge is gradually digested, and keep the rotating treatment assembly driving the ultrasonic composite treatment assembly to rotate together.

[0019] Third step: As the two ends of the ultrasonic composite treatment assembly rotate along the annular groove, the special-shaped magnetic block one and the special-shaped magnetic block two on the outer side of the adapter plate rotate between a group of arc-shaped magnetic block one and arc-shaped magnetic block two. Under the action of the same-sex repulsion and opposite-sex attraction of the magnetic blocks, the magnetic force causes the special-shaped magnetic block one and the special-shaped magnetic block two on the adapter plate to flip between the arc-shaped magnetic block one and the arc-shaped magnetic block two, and drive the ultrasonic composite treatment assembly to rotate self. The ultrasonic transducer and the stirring frame flip once in the sludge in the treatment cavity. And as the adapter plate continues to rotate in the annular groove and moves to between the adjacent group of arc-shaped magnetic block one and arc-shaped magnetic block two, since the polar positions between this group of arc-shaped magnetic block one and arc-shaped magnetic block two are reversed at this time, the moving adapter plate flips again, and intermittent flipping of the ultrasonic composite treatment assembly is carried out multiple times during the downward rotation of the treatment cavity to complete the uniform digestion of the sludge filled in the treatment cavity.

[0020] Fourth step: When the treatment cavity rotates from the top to the bottom, it is communicated with the discharge port, and the internally treated sludge flows out quickly.

[0021] Fifth step: As the treatment inner cylinder continues to rotate, when the treatment cavity rotates to be communicated with the cleaning port, keep the external flushing pump communicated with the conduction pipe, introduce the cleaning water into the cleaning port and input it into the treatment cavity to immediately clean the ultrasonic composite treatment assembly and the treatment cavity. After the cleaning is completed, the treatment cavity rotates to the upper part for the next round of continuous treatment.

[0022] The beneficial effects of the present invention are as follows:

[0023] (1) By utilizing the cooperation between the ultrasonic composite treatment component and the magnetic commutation mechanism, during the rotation from top to bottom along the arc trajectory, and in coordination with the magnetic pole arrangement of the first arc-shaped magnet and the second arc-shaped magnet, when the ultrasonic composite treatment component rotates following the treatment inner cylinder, it simultaneously undergoes intermittent flipping itself, and agitates and applies commutation ultrasonic waves to the sludge in the treatment chamber. On the one hand, it mechanically agitates the internal sludge, making the sludge distribution uniform, avoiding sedimentation, and enhancing the uniform digestion effect of the ultrasonic transducer on the sludge. On the other hand, it dynamically changes the output direction of the circumferentially distributed ultrasonic transducers, providing uniform action on the sludge, comprehensively improving the sludge digestion uniformity, thereby enhancing the actual digestion efficiency, avoiding local sedimentation and omission, and greatly improving the actual digestion treatment effect.

[0024] (2) By utilizing the driving component to drive the rotation of the treatment inner cylinder, and in coordination with the cooperation of the inlet pipe and the discharge port, and by using the ultrasonic composite treatment component built in the treatment chamber, it realizes automatic filling when rotating to the upper part, and completes efficient and sufficient sludge digestion treatment during the downward rotation. At the same time, it completes automatic discharging when rotating to the lower part. The entire treatment process is continuous and stable, enabling continuous and stable continuous treatment, avoiding intermediate pauses for feeding and discharging operations. The continuous working efficiency is high, and the continuous treatment is automatically completed. Only rotation driving is required, without special control. The structure is simple, the input cost is low, and the use effect is good.

[0025] (3) By once again utilizing the treatment inner cylinder that slowly rotates inside the treatment outer cylinder, in coordination with the ultrasonic composite treatment component assembled in the treatment chamber, and in coordination with the cleaning port and the installation arc plate opened on the other side of the treatment outer cylinder, after the sludge in the treatment chamber is emptied after digestion, by adding a cleaning port on the rotation path, when the treatment chamber rotates to the cleaning port, the inside of the emptied treatment chamber is rinsed, and in coordination with the ultrasonic composite treatment component built in the treatment chamber, while rinsing the inside of the treatment chamber, the internal ultrasonic composite treatment component is also rinsed. The rinsing efficiency is high and the rinsing is comprehensive. By using the rotation continuous treatment method, the treatment chamber can be rinsed after each group of sludge treatments, that is, the alternation of sludge treatment emptying and rinsing is realized, effectively avoiding sludge sedimentation, and effectively avoiding the blockage of the ultrasonic composite treatment component, which affects the treatment effect, ensuring the stability of the digestion treatment intensity, and having a good use effect.

[0026] (4) The present invention realizes the internal hot air guidance of the ultrasonic composite treatment component by using the air guiding airway, cooperates with the two groups of annular grooves on both sides inside the treatment outer cylinder, and cooperates with the air inlet holes and exhaust holes on both sides of the treatment outer cylinder to realize the import and export of hot air, and ensures that the import diameter is large and the export diameter is small. At the same time, by utilizing the hollow characteristic inside the stirring frame, the hot air is fully introduced into the stirring frame to heat-treat the sludge. By means of the temperature-raising effect, the sludge digestion rate is increased, and in cooperation with the automatically rotating stirring frame, the heat exchange uniformity is provided.

[0037] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without making creative efforts shall fall within the protection scope of the present invention.

[0038] As Figures 1 to 9 shown, an ultrasonic sludge digestion device capable of continuous processing and its processing method are provided in an embodiment of the present invention, including a processing outer cylinder 1, an inlet pipe 2 fixedly connected to the top of the processing outer cylinder 1, a rotating processing assembly rotatably installed inside the processing outer cylinder 1, an ultrasonic composite processing assembly 8 rotatably installed inside the rotating processing assembly, a driving assembly 3 fixedly provided on the back of the processing outer cylinder 1, the driving assembly 3 controls the rotation of the rotating processing assembly, a magnetic commutation mechanism is provided inside the processing outer cylinder 1, and the magnetic commutation mechanism controls the ultrasonic composite processing assembly 8 to swing intermittently in the rotating processing assembly. A discharge port 14 is opened at the bottom of the processing outer cylinder 1. The rotating processing assembly includes a processing inner cylinder 5, a rotating shaft 4, a first gear 6, and a processing chamber 7. The processing chambers 7 are symmetrically opened on the upper and lower sides of the processing inner cylinder 5. The processing inner cylinder 5 is rotatably sleeved inside the processing outer cylinder 1 through the rotating shaft 4. The magnetic commutation mechanism includes an annular groove 9, an arc-shaped magnetic block 10, and an arc-shaped magnetic block 11. The arc-shaped magnetic blocks 10 and 11 correspond to each other and are both fixedly nested in the annular groove 9.

[0039] Embodiment 1: The sludge to be treated is input into the interior of the treatment outer cylinder 1 along the inlet pipe 2, and the driving assembly 3 is started. The motor 31 in the driving assembly 3 drives the second gear 32 to rotate, and drives the engaged rotating treatment assembly to rotate. The first gear 6 is driven to rotate by the second gear 32, so that the rotating shaft 4 drives the treatment inner cylinder 5 to rotate. When the treatment cavity 7 on the outer side of the treatment inner cylinder 5 rotates to the vertical state, the sludge fed along the inlet pipe 2 is quickly filled into the treatment cavity 7. At the same time, the ultrasonic composite treatment assembly 8 is started. The ultrasonic transducer 82 is started through the embedded ultrasonic generator and acts on the sludge. The acoustic wave action causes the sludge to vibrate internally, causing the sludge to gradually decompose. And the rotating treatment assembly is kept driving the ultrasonic composite treatment assembly 8 to rotate together. As the two ends of the ultrasonic composite treatment assembly 8 rotate along the annular groove 9, the special-shaped magnetic block one 84 and the special-shaped magnetic block two 85 on the outer side of the adapter plate 83 rotate between a group of arc-shaped magnetic blocks one 10 and arc-shaped magnetic blocks two 11. Under the action of the same-sex repulsion and opposite-sex attraction of the magnetic blocks, the magnetic force causes the special-shaped magnetic block one 84 and the special-shaped magnetic block two 85 on the adapter plate 83 to flip between the arc-shaped magnetic block one 10 and the arc-shaped magnetic block two 11, and drives the ultrasonic composite treatment assembly 8 to rotate self. The ultrasonic transducer 82 and the stirring frame 86 flip once in the sludge in the treatment cavity 7. And as the adapter plate 83 continues to rotate in the annular groove 9 and moves to between the adjacent group of arc-shaped magnetic blocks one 10 and arc-shaped magnetic blocks two 11, since the polar positions between this group of arc-shaped magnetic blocks one 10 and arc-shaped magnetic blocks two 11 are reversed at this time, the moving adapter plate 83 flips again. During the downward rotation of the treatment cavity 7, the intermittent flipping of the ultrasonic composite treatment assembly 8 is performed multiple times to complete the stirring and uniform decomposition of the sludge filled in the treatment cavity 7. When the treatment cavity 7 rotates from the top to the bottom, it is communicated with the discharge port 14, and the internally treated sludge quickly flows out.

[0040] First of all, by using the cooperation of the ultrasonic composite treatment assembly 8 and the magnetic commutation mechanism, during the rotation from top to bottom along the arc track, with the cooperation of the magnetic pole arrangement of the arc-shaped magnetic block one 10 and the arc-shaped magnetic block two 11, during the rotation of the ultrasonic composite treatment assembly 8 following the treatment inner cylinder 5, it flips intermittently by itself and performs stirring and commutation ultrasonic action on the sludge in the treatment cavity 7. On the one hand, the internal sludge is stirred mechanically to make the sludge distribution uniform, avoid sedimentation, and improve the uniform decomposition effect of the ultrasonic transducer 82 on the sludge. On the other hand, the output direction of the surrounding ultrasonic transducers 82 is dynamically changed to provide the uniformity of the action on the sludge, comprehensively improve the uniformity of sludge decomposition, thereby improving the actual decomposition efficiency, avoiding local sedimentation and omission, and greatly improving the actual decomposition treatment effect.

[0041] In addition, by using the driving component 3 to drive the rotation of the processing inner cylinder 5, in cooperation with the inlet pipe 2 and the discharge port 14, and by using the ultrasonic composite processing component 8 built in the processing chamber 7, automatic feeding is achieved when it rotates to the upper part, efficient and sufficient sludge digestion treatment is completed during the downward rotation, and automatic discharging is completed when it rotates to the lower part. The entire processing process is continuous and stable, enabling continuous and stable continuous processing, avoiding intermediate pauses for feeding and discharging operations, having high continuous working efficiency, and the continuous processing being automatically completed. Only rotation driving is required without special control, with a simple structure, low input cost, and good use effect.

[0042] Embodiment 2: As the processing inner cylinder 5 continues to rotate, when the processing chamber 7 rotates to communicate with the cleaning port 15, keep the external cleaning pump connected to the conducting pipe 17, and introduce the cleaning water into the cleaning port 15 and then into the processing chamber 7 to immediately clean the ultrasonic composite processing component 8 and the processing chamber 7.

The rinsing efficiency is high and the rinsing is comprehensive. Using the rotation continuous processing method, the processing chamber 7 can be rinsed after each group of sludge treatments, that is, the alternate treatment of sludge treatment emptying and rinsing is realized, effectively avoiding sludge deposition, and effectively avoiding the blockage of the ultrasonic composite processing component 8, which affects the processing effect, ensuring the stability of the digestion treatment intensity, and having a good use effect.

10. A treatment method for an ultrasonic sludge digestion device capable of continuous treatment according to any one of claims 1-9, characterized in that: It includes the following treatment steps: The first step: Input the sludge to be treated along the inlet pipe (2) into the inside of the treatment outer cylinder (1), and start the driving component (3). The driving component (3) drives the engaged rotating treatment component to rotate, so that the rotating shaft (4) drives the treatment inner cylinder (5) to rotate. The second step: When the treatment cavity (7) on the outer side of the treatment inner cylinder (5) rotates to the vertical state, the sludge fed along the inlet pipe (2) is quickly filled into the treatment cavity (7). At the same time, start the ultrasonic composite treatment component (8). The ultrasonic transducer (82) is started and acts on the sludge, so that the sludge is gradually decomposed, and keep the rotating treatment component driving the ultrasonic composite treatment component (8) to rotate together. Step 3: As both ends of the ultrasonic composite treatment component (8) rotate along the annular groove (9), the special-shaped magnet one (84) and the special-shaped magnet two (85) on the outer side of the adapter plate (83) rotate between a set of arc-shaped magnets one (10) and arc-shaped magnets two (11). Under the action of the repulsion between like poles and attraction between opposite poles of the magnets, the magnetic force causes the special-shaped magnet one (84) and the special-shaped magnet two (85) on the adapter plate (83) to flip between the arc-shaped magnet one (10) and the arc-shaped magnet two (11), driving the ultrasonic composite treatment component (8) to rotate self - sufficiently.

And as the adapter plate (83) continues to rotate in the annular groove (9) and moves to between the adjacent set of arc-shaped magnets one (10) and arc-shaped magnets two (11), since the polarity positions between this set of arc-shaped magnets one (10) and arc-shaped magnets two (11) are reversed at this time, the moving adapter plate (83) flips again. During the downward rotation of the treatment chamber (7), intermittent flips of the ultrasonic composite treatment component (8) are carried out multiple times to complete the uniform digestion of the sludge filled in the treatment chamber 7; Step 4: When the treatment chamber (7) rotates from the top to the bottom, it is communicated with the discharge port (14), and the sludge with the internal treatment completed flows out quickly; Step 5: As the treatment inner cylinder (5) continues to rotate, when the treatment chamber (7) rotates to be connected with the cleaning port (15), keep the external cleaning pump connected to the conduction pipe (17), and the cleaning water is introduced into the cleaning port (15) and then input into the treatment chamber (7) to immediately clean the ultrasonic composite treatment component (8) and the treatment chamber (7). After the cleaning is completed, the treatment chamber (7) rotates upward to carry out the next round of continuous treatment.
