Description

Technical Field

[0001] The invention belongs to the technical field of environmental protection equipment, and in particular relates to an omnidirectional stirring device for preventing sludge from compacting. Background Art

[0002] A sedimentation tank is a structure that uses sedimentation to remove suspended matter from water. It is a water purifier that uses the natural sedimentation of water or the coagulation and sedimentation to remove suspended matter from the water. When treating sewage, a sludge scraper will be installed in the primary sedimentation tank. The sludge at the bottom of the primary sedimentation tank is collected in the sludge collecting pit at the center of the bottom of the tank by the operation of the sludge scraper. The sludge is then pumped to the sludge press by a sludge pump to be compacted, so that the sludge in the primary sedimentation tank is stably discharged from the inside of the primary sedimentation tank. It is a commonly used processing equipment for sewage sedimentation.

[0003] When the existing sewage is subjected to sedimentation treatment, a sludge scraper and suction machine is installed in the primary sedimentation tank. However, when the precipitated sludge is large, the mud on the upper part of the scraper and suction machine will become compacted, and the scraper of the scraper and suction machine cannot collect all of this sludge into the sludge collecting pit, resulting in more and more sludge on the upper part of the scraper and suction machine. The amount of mud gradually increases, the resistance of the scraper increases, and the sludge scraper is damaged due to the increase in torque. The sludge cannot be collected in the sludge collecting pit, and the sludge pump cannot pump the sludge into the sludge press. The efficiency of the sludge press is reduced and the energy consumption increases. If the increase in the amount of mud causes the equipment to stop operating, it will not only affect the operation of the system, but also require personnel to clean it up, which is time-consuming and labor-intensive.

[0031] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below in conjunction with the accompanying drawings.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present invention, but the present invention may also be implemented in other ways different from those described herein, and those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0033] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure or characteristic that may be included in at least one implementation of the present invention. The term "in one embodiment" that appears in different places in this specification does not refer to the same embodiment, nor is it a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0034] Depend on Figure 1 , Figure 2 and Figure 3 As shown, it is a structural schematic diagram of the omnidirectional stirring device in this embodiment, including a central working bridge 1, a bearing plate 2, a lifting bracket 3 and a lifting side frame 4, the bearing plate 2 is symmetrically installed on the primary sedimentation tank, the central working bridge 1 is installed in the primary sedimentation tank, the end of the bearing plate 2 is connected to the central working bridge 1, and a lifting bracket 3 is arranged on the side of the bearing plate 2. There are two groups of lifting brackets 3, and a lifting side frame 4 is slidably installed inside the lifting bracket 3. The bottom end of the lifting side frame 4 is installed with a stirring mechanism 6 for stirring the sludge in the primary sedimentation tank.

[0035] During use, the sewage to be precipitated is poured into the primary sedimentation tank, and then the sludge will automatically accumulate on the bottom of the water by utilizing the difference in density between the water source and the impurities. The sludge in the primary sedimentation tank is cleaned by the operation of the scraper and suction sludge machine installed outside the central working bridge 1, so that the subsequent primary sedimentation tank can discharge the sludge from the inside, complete the preliminary treatment of the sewage, and separate the sludge in the sewage from the water source.

[0036] By the attached Figure 7 and Figure 8 As shown, it is a structural schematic diagram of the stirring mechanism 6 in this embodiment, the stirring mechanism 6 includes a connecting shell 61, a driving motor 62, an agitator 63, a connecting cross bar 64, a winding assembly 65 and a calibration wheel 66, the connecting cross bar 64 is fixedly installed at the bottom end of the lifting side frame 4, the connecting shell 61 is installed on the outside of the connecting cross bar 64, the driving motor 62 is installed at the bottom of the connecting shell 61, and the agitator 63 is installed at the output end of the driving motor 62. The stirring of the agitator 63 is used to stir the sludge in the primary sedimentation tank, the winding assembly 65 is installed on one side of the inner wall of the lifting side frame 4, the calibration wheel 66 is installed on the top of the inner wall of the lifting side frame 4, and a steel cable is wound around the outside of the winding assembly 65. The steel cable passes through the calibration wheel 66 and the end of the steel cable is connected to the side wall of the driving motor 62.

[0037] During use, the connecting shell 61 and the driving motor 62 are installed on the outside of the connecting cross bar 64. Under the action of the weight and gravity of the connecting shell 61 and the driving motor 62, the driving motor 62 and the connecting shell 61 rotate along the outer surface of the connecting cross bar 64, so that the agitator 63 is perpendicular to the primary sedimentation tank. Subsequently, through the operation of the driving motor 62, the agitator 63 stirs and crushes the sludge in the primary sedimentation tank to prevent the sludge from accumulating in the primary sedimentation tank for too long, causing agglomeration and coagulation, resulting in the subsequent scraper and suction sludge being unable to effectively and stably clean the sludge in the primary sedimentation tank. Before the driving motor 62 is operated, through the operation of the winding assembly 65, the winding assembly 65 can adjust the length of the output steel cable, so that the steel cable pulls the driving motor 62, allowing the connecting shell 61 to rotate along the outer surface of the connecting cross bar 64, adjusting the angle of the agitator 63 itself, and realizing flexible adjustment of the stirring angle of the agitator 63.

[0038] By the attached Fig. 9 and Fig.10 As shown, it is a schematic diagram of the structure of the winding assembly 65 in this embodiment, the winding assembly 65 includes a mounting bracket 651, a winding roller 652, a shaking handle 653, a ratchet 654, a pawl 655 and a supporting side plate 656, the mounting bracket 651 is fixedly mounted on the inner wall of the lifting side frame 4, the winding roller 652 is rotatably mounted on the side of the mounting bracket 651, the supporting side plate 656 is mounted on the side of the mounting bracket 651, the supporting side plate 656 is rotatably connected to the end of the winding roller 652, the shaking handle 653 is rotatably mounted on the side of the supporting side plate 656, and the end of the shaking handle 653 is The part passes through the supporting side plate 656 and is connected to the end of the winding roller 652. The ratchet 654 is installed at the end of the winding roller 652, and the pawl 655 is installed on the side wall of the supporting side plate 656. When the ratchet 654 rotates in the counterclockwise direction, it will push the pawl 655 to tilt upward at an overall angle. Torsion springs are installed on both sides of the pawl 655. Under the action of the torsion spring, the pawl 655 will deflect to the side close to the ratchet 654. When the ratchet 654 rotates in the clockwise direction, the pawl 655 will be stuck between the teeth outside the ratchet 654 in the initial state to prevent the ratchet 654 from rotating.

[0039] When the angle of the agitator 63 needs to be adjusted during use, the shaking handle 653 is turned to drive the shaking handle 653 to rotate counterclockwise, so that the shaking handle 653 drives the winding roller 652 to rotate as a whole. At this time, the winding roller 652 winds up the steel cable wrapped around the outside. As the length of the steel cable shortens, the steel cable will pull the drive motor 62, so that the angles of the drive motor 62 and the agitator 63 are offset, thereby changing the overall angle of the agitator 63. When the shaking handle 653 is rotated, the ratchet 655 will be installed at the torsion spring on the side. Under the action, it continuously squeezes one side of the ratchet 654, allowing the pawl 655 to be stuck between the teeth of the ratchet 654, completing the limitation of the output length of the steel cable, and preventing the steel cable from being separated from the outside of the winding roller 652 under the pull of the weight of the driving motor 62. When the length of the steel cable needs to be extended and output, the end of the pawl 655 is pressed to make the pawl 655 disengage from the teeth of the ratchet 654, and the limitation of the pawl 655 on the ratchet 654 is released, so that the steel cable can be output, and the angle of the agitator 63 is flexibly adjusted, thereby expanding the overall working range of the agitator 63.

[0040] By the attached Figure 4 As shown, it is a structural schematic diagram of the lifting mechanism 5 in this embodiment. The omnidirectional stirring device also includes a lifting mechanism 5, and the lifting mechanism 5 includes a telescopic component 51, an anti-slip shell 52, a moving wheel 53 and a moving guide rail 54. The telescopic component 51 is installed in the lifting bracket 3, the anti-slip shell 52 is fixedly installed on the side of the lifting bracket 3, the moving guide rail 54 is installed on the side wall of the bearing plate 2, the anti-slip shell 52 is slidably connected to the moving guide rail 54, and the moving wheel 53 is installed on the anti-slip shell 52. The moving wheel 53 rolls along the length direction of the moving guide rail 54.

[0041] During the overall operation of the device, the amount of sludge in the primary sedimentation tank is checked, and the telescopic assembly 51 is operated according to the amount of sludge. The telescopic assembly 51 is locked for overall operation, and the taut steel cable connected to the lifting side frame 4 on the outside of the telescopic assembly 51 becomes loose. At this time, the lifting side frame 4 moves toward the bottom of the primary sedimentation tank under the weight of the bottom part of the lifting side frame 4, and the distance between the bottom of the lifting side frame 4, the stirring mechanism 6 and the inner wall of the bottom of the primary sedimentation tank is adjusted to facilitate the stirring mechanism 6 to effectively treat the sludge. The telescopic assembly 51 can also reel in the steel cable, so that the lifting side frame 4 moves toward the side close to the telescopic assembly 51. The stirring mechanism 6 is moved to adjust the depth and position of the stirring mechanism 6 in the primary sedimentation tank, and then the overall angle of the stirrer 63 is adjusted through the cooperation of the winding assembly 65 and the calibration wheel 66. After the adjustment is completed, the moving wheel 53 moves along the side wall of the moving guide rail 54 through the operation of the moving wheel 53, driving the lifting bracket 3 and the lifting mechanism 5 as a whole to move, and the stirrer 63 is moved to the target position as a whole, further expanding the working range of the stirrer 63, allowing the stirrer 63 to move along the side wall of the supporting plate 2 as a whole, and assisting the stirrer 63 to stably crush the sludge inside the primary sedimentation tank to prevent the sludge from agglomerating.

[0042] In this embodiment, the moving wheel 53 is composed of a moving roller, a motor and a reducer. The output end of the motor is connected to the reducer. The moving roller is installed in the anti-slip shell 52. When the motor is running, the moving roller will roll against the side wall of the moving guide rail 54, driving the lifting mechanism 5 and the lifting bracket 3 to move horizontally as a whole.

[0043] By the attached Figure 5 and Figure 6 As shown, it is a structural schematic diagram of the telescopic component 51 in this embodiment, the telescopic component 51 includes a connecting frame 511, an electric hoist 512, a hook 513 and a hanging plate 514, the connecting frame 511 is installed in the lifting bracket 3, the electric hoist 512 is installed at the bottom of the connecting frame 511, the hook 513 is arranged at the bottom of the electric hoist 512, the hook 513 and the electric hoist 512 are connected by a steel cable, the hanging plate 514 is fixedly installed on the inner wall of the lifting side frame 4, and the hook 513 is connected to the hanging plate 514.

[0044] During use, the electric hoist 512 is operated, and the length of the steel cable wrapped around the outside of the electric hoist 512 changes according to the rotation direction of the electric hoist 512, so that the distance between the hook 513 and the electric hoist 512 changes. At this time, the lifting side frame 4 slides as a whole along the lifting bracket 3 under the cooperation of gravity and the weight of each component at the bottom of the lifting side frame 4, and adjusts the depth of the agitator 63 entering the primary sedimentation tank.

[0045] By the attached Figure 5As shown, a lifting kit is installed between the two sets of lifting brackets 3 , the lifting kit is slidably connected to the lifting side frame 4 , and the side of the lifting kit is connected to the telescopic component 51 .

[0046] During use, the composition of the lifting bracket 3 and the lifting kit provides a stable platform for the installation of the telescopic component 51. When the movable wheel 53 is in operation, it can also drive the lifting bracket 3, the lifting kit and the components installed on the lifting bracket 3 to move synchronously. When the telescopic component 51 is in operation as a whole, as the length of the steel cable changes, the lifting side frame 4 will slide in the lifting kit, causing the distance between the lifting side frame 4 and the inner wall of the primary sedimentation tank to change, thereby assisting the stable lifting and lowering movement of the lifting side frame 4.

[0047] By the attached Figure 2 , Figure 3 and Fig.11 As shown, the omnidirectional stirring device also includes a walking mechanism 7, which includes a fixed block 71, a connecting shaft 72, a mounting top plate 73 and a driving wheel assembly 74. The connecting shaft 72 is installed on one side of the bottom end of the load-bearing plate 2, and the mounting top plate 73 is installed on the other side of the bottom end of the load-bearing plate 2. The fixed block 71 is installed at the bottom end of the connecting shaft 72, and the driving wheel assembly 74 is installed at the bottom end of the mounting top plate 73. A conveying guide rail is installed at the bottom end of the driving wheel assembly 74 at the edge of the primary sedimentation tank, and the driving wheel assembly 74 rolls along the conveying guide rail, and a limiting block is installed on the outside of the conveying guide rail. A rotating ring is installed on the upper surface of the central working bridge 1, and the upper surface of the rotating ring is connected to the bottom end of the fixed block 71.

[0048] During use, the driving wheel assembly 74 will move along the conveying guide rail installed at the edge of the primary sedimentation tank through the operation of the driving wheel assembly 74. At this time, the overall angle of the supporting plate 2 changes. With the cooperation of the connecting shaft 72 and the fixed block 71, the supporting plate 2 as a whole performs a cyclical reciprocating movement around the central working bridge 1, adjusting the overall stirring position of the agitator 63, realizing the circumferential movement of the position of the agitator 63, and further expanding the overall working range of the agitator 63.

[0049] The above content is a further detailed description of the present invention in combination with specific implementation methods. It cannot be determined that the specific implementation of the present invention is limited to these descriptions.
