DETAILED DESCRIPTION OF THE INVENTION The present invention provides a method for removing impurities from sewage containing impurities such as sewage, industrial wastewater, human waste, etc., and dehydrating water in the impurities. Conventionally, it is related to removal and dehydration equipment.
There are various products available for removing impurities from sewage, such as vibrating separators that sift out impurities by vibrating a perforated plate filter horizontally, and vibrating separators that sift out impurities by horizontally vibrating a perforated plate filter, and a vibrating separator in which a thin wire is spirally wound inside a rotating drum. For example, there is a drum wire separator that arranges bamboo shoots at regular intervals and wraps them around a wire.

However, the former requires cleaning at regular intervals due to clogging, and the latter has the disadvantage that repairing the wire is difficult. Furthermore, the separated waste contained a large amount of water, so it could not be burned as is and had to be dehydrated using separate equipment.
For this purpose, a screw press device is used, which has a screw inside the drum and performs compression dehydration using the compressive force of the screw.However, in this device, the distance between the screw and drum 0 is large, so impurities escape from this distance. As a result, the compression effect was not sufficiently performed, resulting in extremely low efficiency. In view of this point, the present invention provides a dehydration device for removing impurities that can easily remove impurities from wastewater, and at the same time dehydrate the impurities to the extent that they can be combusted.

On the other hand, the outer frame 25, side plates 27, and compression plate 29 are integrally fixed to the frame 26 and cannot rotate in any way. Further, the sleeve 12 is moved from side to side in the direction of the bag by the movement of the air cylinder 19, the moving arm 20 and the operating arm 17, and as a result, the shielding plate 16 is moved from side to side within the dewatering drum 22. When the motor 36 is operated, its rotational output is transmitted to the rotating shaft 7 via the coupling 37, and the air cylinder 9, which rotates the sleeve 12 and the dehydration drum 22, moves the sleeve 12 left and right at a constant cycle. Move by sliding.

When sewage containing impurities is put into the tank 2 in this state, the sewage flows into the introduction path 8 via the L-shaped Z pipe 4. A rotary valve 1 is installed between the L-shaped pipe 4 and the introduction path 8.
1 prevents wastewater from flowing out. The wastewater flowing into the introduction path 8 passes through the outlet 9 and the discharge Z-row 4, and is discharged into the dewatering drum 22.

The dewatering drum 22 functions similarly to a well-known centrifuge,
The impurities in the waste water are retained on the inner wall of the dehydration drum 22, and only water passes through the dehydration holes 23 and is discharged into the space within the outer frame 25. This released water collects at the lower part of the outer frame 25 due to its own weight and is discharged to the outside through the closing port 33, the chute 34, and the drain port 35 in this order. Since the sleeve 12 moves from side to side, the outer periphery of the shielding plate 16 fixed to the sleeve 12 can be removed from the dehydration drum by removing foreign matter held on the inner wall of the dehydration drum 22. As shown in FIG. 5, the shielding plate 16 moves toward the left and right side plates 27 so as to scrape off impurities held on the inner wall of the dehydration drum 22.

When a certain amount of impurities are collected, the impurities are compressed by the compression plate 29 and the shielding plate 16 which are in close contact with the side plate 27 by the 'coat 31, and are further dehydrated. At this time, since the compression plate 29 is fixed and the dewatering drum 22 is rotating, the mixed material receives a compressive force at the end position of the stroke of the shielding plate 16, and at the same time receives stress due to shearing, causing friction within the foreign material. Heat is generated which further dries out the moisture in the hybrid. In this way, if the hazardous material that has flowed in from the introduction path 8 remains on the surface of the compression plate 29, it will not be able to withstand the pressure of the shielding plate 16 due to its volume, and will move against the pressure of the spring 31, causing the compression plate 29 to
is separated from the side plate 27 to open a discharge gap c, and the dehydrated impurities are discharged to the outside from this gap c.

At this time, the impurities are smoothly guided by the tapered portion 32. Although not shown, by providing a conveyor or the like below the gap c, the hazardous materials can be automatically transferred to another process. In this way, the waste matter in the waste water is dehydrated and dried by the centrifugal force of the dehydration drum 22, the compressive force of the shielding plate 16 and the compression plate 29, and the frictional heat generated in the waste water. The inflow of the dewatering drum 22 passes through the left half of the discharge row 4 and into the left side space of the dewatering drum 22 when the shielding plate 16 moves rightward in FIG.

At this time, the shielding plate 16 opposes the compression plate 29 on the right side and scrapes off impurities, and the inflow, separation, and dehydration of wastewater are performed in parallel. As a result of the outer periphery of the shielding plate 16 moving in close contact with the inner wall of the dehydration drum 22, the dehydration hole 23 of the dehydration drum 22 is prevented from being clogged with impurities, and the dehydration hole 23 is also prevented from being clogged.
Since the outer periphery of the dehydration drum 22 has a bulge b in its cross-sectional shape, foreign matter adheres to the inner wall side a of the dehydration drum 22, and even if the dehydration hole 23 is closed, the foreign matter adheres to the inner wall. Because of its small area, it easily separates due to centrifugal force and prevents clogging.

Since the present invention is configured as described above, the impurities in wastewater are continuously removed and dehydrated at the same time, so there is no need for multiple separators, dewatering machines, and dryers as in the past, resulting in high work efficiency. It is.

In addition to centrifugal separation using a drum, dehydration is also highly effective because it is compressed using a shielding plate and a compression plate.Furthermore, since frictional heat also contributes to the dehydration process, the removed There is no need for a heat source to dry miscellaneous items.
Compared to conventional equipment, the structure is simpler and the occurrence of breakdowns is extremely low, and the removed impurities have a high degree of dryness, so they can be burned as they are and are easy to dispose of.
