When the sludge reaches a certain amount, the gantry supports the oil cylinder, and the telescopic end of the oil cylinder pushes the pressure plate. At this time, the pressure plate squeezes the sludge inside the trough body, so that the sludge is squeezed to form a sludge block. When the extrusion is completed, the oil cylinder contracts and drives the pressure plate to move up. At this time, the handle is pulled to pull out and transfer the trough body.

The outer shell is connected to the flocculation tank, and the sewage inside the flocculation tank enters the filter tube. At this time, when the motor rotates, it drives the rotating shaft, and the spiral stacking pieces on the surface of the rotating shaft rotate to drive the sludge to move upward. The surface of the filter tube is divided into dynamic ring pieces and static ring pieces, which are arranged alternately. When the spiral stacking pieces rotate, the sewage is discharged from the filter gap of the filter tube, and the sludge moves upward along the rotating shaft and is discharged from the mud outlet. At this time, the sewage falls on the surface of the primary filter plate, and the primary filter plate performs secondary impurity filtration on the sewage. The activated carbon filter layer blocks and adsorbs impurities in the sewage, and finally falls into the water storage tank. When drainage is required, the water pipe is connected to the drain outlet to discharge the filtered water inside the storage tank, thereby improving the adaptability of the device.

[0027] In this embodiment, the sludge slides from the mud discharge inclined plate 51 into the trough body 56 inside the box body 52. ​​At this time, the baffle 57 on the surface of the mud discharge inclined plate 51 prevents the sludge from sliding out of the machine, thereby ensuring the hygiene of the site when the device is in use. When the sludge reaches a certain amount, the gantry 53 supports the oil cylinder 54, and the telescopic end of the oil cylinder 54 pushes the pressure plate 55. At this time, the pressure plate 55 squeezes the sludge inside the trough body 56, so that the sludge is squeezed to form a sludge block. When the extrusion is completed, the oil cylinder 54 contracts and drives the pressure plate 55 to move upward. At this time, the handle 58 is pulled to pull out and transfer the trough body 56. This device enables the dehydrated sludge to be collected and sorted, so that it will not pollute the use site, thereby improving the adaptability of the device.

[0028] Example 2

[0029] like Figure 1-5 As shown, on the basis of Example 1, the present invention provides a technical solution: preferably, the filtering mechanism 4 includes a shell 41, which is fixedly mounted on the surface of the flocculation tank 3, and a filter tube 42 is fixedly mounted inside the shell 41, and a mud outlet 48 is fixedly mounted at one end of the filter tube 42, and the mud outlet 48 is adapted to the mud discharge inclined plate 51, and a primary filter plate 43 is fixedly mounted inside the shell 41, and an activated carbon filter layer 410 is fixedly mounted at the bottom end of the primary filter plate 43, and a water storage tank 44 is provided at the bottom end of the activated carbon filter layer 410, and a drain outlet 49 is fixedly mounted on the surface of the shell 41, and the filtering mechanism 4 also includes a motor 47, which is fixedly mounted on the surface of the shell 41, and a rotating shaft 46 is fixedly mounted on the output end of the motor 47, and a stacked spiral piece 45 is fixedly mounted on the surface of the rotating shaft 46, and the stacked spiral piece 45 is movably mounted on the surface of the filter tube 42.

[0030] In this embodiment, the flocculation tank 3 is connected through the outer shell 41, and the sewage inside the flocculation tank 3 enters the filter tube 42. At this time, the motor 47 drives the rotating shaft 46 when it rotates, and the spiral sheets 45 on the surface of the rotating shaft 46 rotate to drive the sludge to move upward. The surface of the filter tube 42 is divided into dynamic ring sheets and static ring sheets, which are arranged alternately. When the spiral sheets 45 rotate, the sewage is discharged from the filter gap of the filter tube 42, and the sludge moves upward along the rotating shaft 46 and is discharged from the mud outlet 48. At this time, the sewage falls on the surface of the primary filter plate 43, and the primary filter plate 43 performs secondary impurity filtration on the sewage. The activated carbon filter layer 410 blocks and adsorbs impurities in the sewage, and finally falls into the water storage tank 44. When drainage is required, the water pipe is connected to the drain outlet 49 to discharge the filtrate inside the water storage tank 44, thereby improving the adaptability of the device.

[0031] The following is a detailed description of the working principle of the screw-type sludge dewatering machine for sewage treatment.

[0032] like Figure 1-5 As shown, the flocculation tank 3 is connected to the outer shell 41, and the sewage inside the flocculation tank 3 enters the filter tube 42. At this time, the motor 47 rotates to drive the rotating shaft 46, and the spiral discs 45 on the surface of the rotating shaft 46 rotate to drive the sludge to move upward. The surface of the filter tube 42 is divided into dynamic ring pieces and static ring pieces, which are arranged alternately. When the spiral discs 45 rotate, the sewage is discharged from the filter gap of the filter tube 42, and the sludge moves upward along the rotating shaft 46 and is discharged from the mud outlet 48. At this time, the sewage falls on the surface of the primary filter plate 43, and the primary filter plate 43 performs secondary impurity filtration on the sewage. The activated carbon filter layer 410 blocks and adsorbs impurities in the sewage, and finally falls into the water storage tank 44. When drainage is required, the water pipe is connected to the drain outlet 49 to discharge the filtered water inside the water storage tank 44. At the same time, the sludge slides from the mud discharge inclined plate 51 into the trough body 56 inside the box body 52. ​​At this time, the baffle 57 on the surface of the mud discharge inclined plate 51 prevents the sludge from sliding out of the machine, ensuring the hygiene of the site when the device is in use. When the sludge reaches a certain amount, the gantry 53 supports the oil cylinder 54, and the telescopic end of the oil cylinder 54 pushes the pressure plate 55. At this time, the pressure plate 55 squeezes the sludge inside the trough body 56, so that the sludge is squeezed into sludge blocks. When the extrusion is completed, the oil cylinder 54 contracts and drives the pressure plate 55 to move upward. At this time, the handle 58 is pulled to pull out the trough body 56 and transfer it. This device allows the dehydrated sludge to be collected and sorted so that it will not pollute the use site. When drainage is required, the water pipe is connected to the drain outlet 49 to discharge the filtered water inside the water storage tank 44, thereby improving the adaptability of the device.

[0033] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
