Description

Technical Field

[0001] The invention belongs to the technical field of sludge treatment, and in particular relates to a novel mobile sludge treatment spiral screening mechanism and a screening process thereof. Background Art

[0002] When carrying out ecological dredging projects in lakes and other water bodies, the sludge rich in impurities such as industrial waste, construction waste, domestic waste, shellfish, large-size stones, etc. needs to be filtered and separated to separate the impurities in the sludge.

[0003] When traditional sludge treatment equipment is treating sludge with high water content and high viscosity, it is easy to become clogged due to the high viscosity of the sludge, which makes it easy for the sludge to adhere to key components such as the screen during the screening process, forming sediments that are difficult to remove. As the sediments continue to accumulate, the screening channel gradually narrows or even becomes completely blocked, resulting in the sludge being unable to pass through the screening area normally and the solid impurities being unable to be effectively separated. This not only affects the continuity of the screening, but also greatly reduces the screening accuracy, resulting in the separated solid matter still containing a large amount of sludge that has not been effectively separated, making it difficult to meet the requirements of subsequent treatment or resource utilization. Therefore, there are deficiencies and it cannot meet its use requirements. Therefore, it is necessary to further improve it.

[0004] Therefore, in view of this, the existing structure and deficiencies are studied and improved, and a new mobile sludge treatment spiral screening mechanism and screening process are provided, in order to achieve a more practical purpose. Summary of the invention

[0087] The specific usage and function of this embodiment are as follows:

[0088] Working principle: When in use, the sludge is poured into the feed hopper 22, and the drive motor 30 is started by program control. The drive motor 30 drives the rotating shaft 31 to rotate, and drives the feeding spiral blade 23 to push the sludge at the same time, so as to realize automatic feeding of the sludge. With the continuous pushing of the feeding spiral blade 23, the sludge is transported to the screening shell 41, and is transported to the top of the screening drum 42 and the screening filter 43. The combined design of the screening drum 42 and the screening filter 43 realizes effective preliminary screening of the sludge, so that the screened sludge is discharged along the first row of mud buckets 45. The synergistic effect of the screening drum 42 and the screening filter 43 not only ensures the smooth flow of the sludge, but also effectively reduces the influence of the viscosity of the sludge on the screening process through the diversion screening method, thereby avoiding blockage.

[0089] When the screening drum 42 and the screening filter 43 are screening the sludge, the rotating shaft 31 is used to drive the scraper 443 to rotate synchronously, and the scraper 443 can be used to scrape off the sludge filtered on the outer wall of the screening drum 42, so that the scraper 443 can continuously scrape off the high-viscosity sludge attached to the outer wall of the screening drum 42 during operation to prevent clogging; and when the scraper 443 is scraping the screening drum 42, the scraper 443 will contact the pressing component 60 during the rotation process, and based on the pressure of the pressing component 60, the scraper 443 intermittently squeezes the screening drum 42, causing the inner diameter of the screening drum 42 to become smaller, so that the sludge in the screening drum 42 is squeezed outward along the screening holes on the screening drum 42, so as to achieve the screening of the sludge, thereby enhancing the screening efficiency and separation effect of the sludge, and ensuring the initial effective separation between the sludge and the solid particles;

[0090] In addition, the transmission spiral blade 56 is used to drive the initially separated solid particles and sludge to be discharged along the discharge port 511 to the second screening mechanism 80 for further screening, so that the initially separated solid particles and sludge fall on the top of the screening plate 852, and are filtered and screened by the screening plate 852; in addition, during the contact between the scraper 443 and the pressing assembly 60, the pressing plate 63 is squeezed at the same time, and the pressing plate 63 drives the squeezing block 65 to squeeze the fixed airbag 62, driving the gas in the fixed airbag 62 to be transmitted along the ventilation pipe 66 to the ventilation main pipe 70, and then flows through the fixed pipe 82 to be transmitted to the air nozzle 84, and the gas is ejected through the air nozzle 84, and the transmission is driven under the action of the airflow. The blade 832 drives the movable shaft 831 to rotate, and the movable shaft 831 drives the separation plate 833 to rotate, and the rotating separation plate 833 drives the solid particles on the screening plate 852 to flip. Through the mutual collision and friction during the flipping process, the sludge attached to the surface of the solid particles is effectively removed, the purity of the solid particles is effectively improved, and the further separation between the sludge and the solid particles is promoted, which significantly enhances the screening effect. The flipping action of the solid particles driven by the separation plate 833 ensures the all-round and multi-angle screening of the solid particles during the screening process, thereby effectively avoiding the problem of sludge residue on the surface of solid particles commonly seen in traditional screening equipment, and improving the stability and efficiency of the screening quality;

[0091] At the same time, the movable shaft 831 rotates and drives the knocking piece 834 to rotate synchronously, driving the knocking piece 834 to knock the screening plate 852. Under the elastic force of the elastic sealing pad 853 and the screening spring 854, the screening plate 852 generates a specific vibration frequency, thereby realizing enhanced screening of the sludge. The use of vibration screening not only accelerates the separation of fine particles in the sludge, but also promotes the uniform distribution of the sludge on the screening plate 852 through the vibration effect, avoiding the occurrence of local blockage, and can also effectively reduce the sludge in the screening process. The residence time in the process reduces the viscosity change of the sludge during the screening process, and the screened solid particles slide along the screening plate 852 into the discharge hopper 53, and the discharge hopper 53 is used to guide and discharge the screened solid particles, and the guide seat 54 and the second row of mud hoppers 55 are used to discharge the screened sludge; and through the synergistic effect of the separation component 83 and the screening component 85, the sludge and solid particles on the screening plate 852 are separated more fully and effectively during the screening process, which not only improves the screening efficiency, but also ensures the stability and consistency of the screening quality.
