Description

Technical Field

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

[0002] Ultrasonic sludge digestion device is a device that uses ultrasonic technology to treat and degrade sludge. The high-frequency vibration waves generated by ultrasonic waves transfer energy to substances in the sludge, producing 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 ultrasonic sludge digestion device in the prior art, during use, sludge is usually put into a reaction chamber, and the filled sludge is ultrasonically treated with a built-in ultrasonic transducer, and the organic matter in the sludge is degraded and cells are destroyed by the cavitation effect of the ultrasonic wave. However, in the actual treatment process, in order to improve the treatment efficiency, the amount of sludge filled in the reaction chamber is large, the installation position of the ultrasonic transducer located in the sludge is fixed, and the direction of the sound wave is limited. The actual treatment uniformity of the sludge in the reaction chamber is low, so that there are incompletely digested components in the sludge finally discharged. In order to further improve the treatment efficiency, continuous feeding is often required. However, sludge digestion takes time. It is difficult to achieve both continuous feeding and ultrasonic treatment with a stable time. It is often difficult to achieve quick control. It is often necessary to add multiple sets of control equipment to perform multiple coordinated control operations. The electronic control cost is high, the device structure is complex, and the comprehensive treatment effect is not good. Summary of the Invention

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

[0017] Step 1: The sludge to be treated is fed into the inner part of the treatment outer cylinder through the inlet pipe, and the drive assembly is started. The drive assembly drives the engaged rotating treatment assembly to rotate, so that the rotating shaft drives the treatment inner cylinder to rotate;

[0018] Step 2: When the treatment chamber outside the treatment inner cylinder rotates to a vertical state, the sludge fed along the inlet pipe is quickly filled into the treatment chamber, and at the same time, the ultrasonic composite treatment component is started, the ultrasonic transducer is started, and acts on the sludge, causing the sludge to gradually dissolve, and the rotating treatment component drives the ultrasonic composite treatment component to rotate together;

[0019] The third step: as the two ends of the ultrasonic composite treatment component rotate along the annular groove, the special-shaped magnetic block 1 and the special-shaped magnetic block 2 on the outside of the adapter plate rotate to between a group of arc-shaped magnetic block 1 and arc-shaped magnetic block 2. Under the action of like-pole repulsion and opposite-pole attraction of the magnetic blocks, the magnetic force causes the special-shaped magnetic block 1 and the special-shaped magnetic block 2 on the adapter plate to flip between the arc-shaped magnetic block 1 and the arc-shaped magnetic block 2, and drives the ultrasonic composite treatment component to rotate. The ultrasonic transducer and the stirring frame flip once in the sludge in the treatment chamber, and as the adapter plate continues to rotate in the annular groove, it moves to between the adjacent group of arc-shaped magnetic block 1 and arc-shaped magnetic block 2. Since the polarity position between the group of arc-shaped magnetic block 1 and arc-shaped magnetic block 2 is reversed at this time, the moving adapter plate flips again. During the downward rotation of the treatment chamber, the ultrasonic composite treatment component is intermittently flipped multiple times to complete the uniform digestion of the sludge filled in the treatment chamber.

[0020] Step 4: When the processing chamber rotates from the top to the bottom, it is connected to the discharge port, and the sludge that has been processed inside flows out quickly;

[0021] Step 5: As the inner cylinder continues to rotate, when the processing chamber rotates to the cleaning port and is connected, keep the external flushing pump connected to the guide pipe, and the cleaning water flows into the cleaning port and input into the processing chamber to immediately clean the ultrasonic composite processing component and the processing chamber. After cleaning, the processing chamber rotates to the top for the next round of continuous processing.

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

[0023] (1) The present invention utilizes the cooperation of the ultrasonic composite treatment component and the magnetic reversing mechanism. During the top-down rotation along the circular arc trajectory, the magnetic pole arrangement of the arc-shaped magnetic block 1 and the arc-shaped magnetic block 2 is coordinated. During the rotation of the ultrasonic composite treatment component following the inner cylinder of the treatment, the ultrasonic composite treatment component itself is intermittently flipped, and the sludge in the treatment chamber is stirred and reversed by ultrasonic action. On the one hand, the internal sludge is stirred mechanically to provide uniform sludge distribution, avoid deposition, and improve the uniform digestion effect of the ultrasonic transducer on the sludge. On the other hand, the output direction of the surrounding distributed ultrasonic transducers is dynamically changed to provide uniform action on the sludge, and the sludge digestion uniformity is comprehensively improved, thereby improving the actual digestion efficiency, avoiding local deposition and omission, and greatly improving the actual digestion treatment effect.

[0024] (2) The present invention utilizes a driving component to drive the rotation of the inner cylinder, and cooperates with the inlet pipe and the discharge port, and utilizes an ultrasonic composite processing component built into the processing chamber to realize automatic filling when rotating to the upper side, and completes efficient and sufficient sludge digestion treatment during the downward rotation. At the same time, automatic discharge is completed when rotating to the lower side. The entire processing process is continuous and stable, and continuous and stable processing can be achieved, avoiding intermediate pauses for feeding and discharging operations. The continuous work efficiency is high, and the continuous processing is automatically completed. Rotational drive can be realized without the need for special control. The structure is simple, the investment cost is low, and the use effect is good.

[0025] (3) The present invention reuses the processing inner cylinder that rotates slowly inside the processing outer cylinder, cooperates with the ultrasonic composite processing component assembled in the processing chamber, and cooperates with the cleaning port and the installation arc plate opened on the other side of the processing outer cylinder. After the sludge in the processing chamber is emptied after digestion, a cleaning port is added on the rotation path. When the processing chamber rotates to the cleaning port, the emptied processing chamber is flushed. In combination with the ultrasonic composite processing component built into the processing chamber, the processing chamber is cleaned while the internal ultrasonic composite processing component is flushed. The flushing efficiency is high and the flushing is comprehensive. By using the continuous rotation processing method, the processing chamber can be flushed after each group of sludge is processed, that is, the alternating processing of sludge treatment emptying and flushing is realized, which effectively avoids sludge deposition and effectively avoids the clogging of the ultrasonic composite processing component to affect the processing effect, thereby ensuring the stability of the digestion treatment intensity and good use effect.

[0026] (4) The present invention realizes the hot air guidance inside the ultrasonic composite treatment component by utilizing the air guide airway, cooperates with the two sets of annular grooves on both sides of the inner side of the treatment outer cylinder, and cooperates with the air inlet and exhaust holes on both sides of the treatment outer cylinder to realize the introduction and export of hot air, and ensures that the introduction diameter is large and the export diameter is small. At the same time, the hollow characteristics of the stirring frame are utilized to fully introduce the hot air into the stirring frame to heat the sludge, utilize the temperature increase effect to improve the sludge digestion rate, and cooperate with the automatically flipping stirring frame to provide heat exchange uniformity.

[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] like Figures 1 to 9 As shown, an embodiment of the present invention provides a continuously treatable ultrasonic sludge digestion device and a treatment method thereof, comprising a treatment outer cylinder 1, an inlet pipe 2 fixedly connected to the top of the treatment outer cylinder 1, a rotating treatment component rotatably installed inside the treatment outer cylinder 1, an ultrasonic composite treatment component 8 rotatably installed inside the rotating treatment component, a driving component 3 fixedly provided on the back of the treatment outer cylinder 1, the driving component 3 controls the rotation of the rotating treatment component, a magnetic reversing mechanism is provided inside the treatment outer cylinder 1, the magnetic reversing mechanism controls the ultrasonic composite treatment component 8 to intermittently swing in the rotating treatment component, a discharge port 14 is provided at the bottom of the treatment outer cylinder 1, the rotating treatment component comprises a treatment inner cylinder 5, a rotating shaft 4, a gear 6 and a treatment chamber 7, the treatment chamber 7 is symmetrically provided on the upper and lower sides of the treatment inner cylinder 5, the treatment inner cylinder 5 is rotatably sleeved on the inside of the treatment outer cylinder 1 through the rotating shaft 4, the magnetic reversing mechanism comprises an annular groove 9, an arc-shaped magnetic block 10 and an arc-shaped magnetic block 2 11, the arc-shaped magnetic block 10 and the arc-shaped magnetic block 2 11 correspond one to one 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 component 3 is started. The motor 31 in the driving component 3 drives the gear 2 32 to rotate, and drives the meshing rotating treatment component to rotate, and drives the gear 1 6 to rotate through the gear 2 32, so that the rotating shaft 4 drives the treatment inner cylinder 5 to rotate. When the treatment chamber 7 on the outer side of the treatment inner cylinder 5 rotates to a vertical state, the sludge fed along the inlet pipe 2 is quickly filled into the treatment chamber 7, and the ultrasonic composite treatment component 8 is started at the same time. The ultrasonic transducer 82 is started by the embedded ultrasonic generator and acts on the sludge. The sound wave causes the internal vibration of the sludge, so that the sludge is gradually digested, and the rotating treatment component drives the ultrasonic composite treatment component 8 to rotate together. As the two ends of the ultrasonic composite treatment component 8 rotate along the annular groove 9, the special-shaped magnetic block 1 84 and the special-shaped magnetic block 2 85 on the outside of the adapter plate 83 rotate to a group of arc-shaped magnetic blocks 1 0 and the arc-shaped magnetic block 2 11, under the action of like-pole repulsion and opposite-pole attraction, the magnetic force causes the special-shaped magnetic block 1 84 and the special-shaped magnetic block 2 85 on the adapter plate 83 to flip between the arc-shaped magnetic block 10 and the arc-shaped magnetic block 2 11, and drives the ultrasonic composite treatment component 8 to rotate. The ultrasonic transducer 82 and the stirring frame 86 flip once in the sludge in the treatment chamber 7, and as the adapter plate 83 continues to rotate in the annular groove 9, it moves to between an adjacent group of arc-shaped magnetic blocks 10 and arc-shaped magnetic blocks 2 11. Since the polarity positions between the group of arc-shaped magnetic blocks 10 and arc-shaped magnetic blocks 2 11 are reversed at this time, the moving adapter plate 83 flips again. During the downward rotation of the treatment chamber 7, the ultrasonic composite treatment component 8 is intermittently flipped multiple times to complete the stirring and uniform digestion of the sludge filled in the treatment chamber 7. When the treatment chamber 7 rotates from top to bottom, it is connected to the discharge port 14, and the sludge that has been processed inside flows out quickly.

On the one hand, the internal sludge is stirred mechanically to provide uniform sludge distribution, avoid deposition, and improve the uniform digestion 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 uniform action on the sludge, and comprehensively improve the uniformity of sludge digestion, thereby improving the actual digestion efficiency, avoiding local deposition and omissions, and greatly improving the actual digestion treatment effect.

[0041] In addition, by utilizing the driving component 3 to drive the rotation of the processing inner cylinder 5, and coordinating with the inlet pipe 2 and the discharge port 14, and utilizing the ultrasonic composite processing component 8 built into the processing chamber 7, automatic filling is achieved when rotating upward, and efficient and sufficient sludge digestion treatment is completed during downward rotation. At the same time, automatic discharge is completed when rotating downward. The entire processing process is continuous and stable, and continuous and stable continuous processing can be achieved, avoiding intermediate pauses for feeding and discharging operations. The continuous work efficiency is high, and the continuous processing is automatically completed. Rotational drive is sufficient, and no special control is required. The structure is simple, the investment cost is low, and the use effect is good.

The flushing efficiency is high and the flushing is comprehensive. By utilizing the continuous rotation processing method, the processing chamber 7 can be flushed after each group of sludge treatment, that is, the alternating treatment of sludge treatment emptying and flushing is realized, effectively avoiding sludge deposition, and effectively avoiding the clogging of the ultrasonic composite processing component 8 and affecting the treatment effect, ensuring the stability of the digestion treatment intensity and good use effect.
