EXAMPLE An example of the present invention shown in the drawings will be described below. A is a vehicle in which a sludge dewatering apparatus C is mounted on a chassis B of a vehicle, and a discharge port 50 is located above a rear space of the chassis B of the vehicle.

Next, the sludge dewatering apparatus C will be described. Reference numeral 1 is a rotary drum, and rings 5 and 6 of the rotary drum 1 are mounted on wheels 3 and 4 arranged on a base 2 in the front and rear. The front plate 7 of the rotary drum 1 is provided with a circular hole 8 concentric with the rotary drum shaft, and an outlet fixing plate 9 is abutted and sealed in the circular hole 8. Reference numeral 10 is a pulley integrated with the front side plate 7, and is driven by a belt 12 from a motor 11 provided on the base 2. The outlet fixing plate 9 is a gutter 13 that connects the inside of the rotary drum 1 to the outside, and a discharge screw 14 is arranged. A belt 16 is provided by a forward / reverse rotation motor 15 provided on the base 2.
It is designed to be driven by.

Reference numeral 18 denotes a rear plate of the rotary drum 1, which is provided with a circular hole 19 concentric with the rotary drum shaft, and an inlet fixing plate 20 is abutted and sealed in the circular hole 19. 21 is a sludge charging hopper,
Reference numeral 22 denotes a sludge charging screw, the shaft tip of which projects from the opening 40 of the inlet fixing plate 20 and is supported by a bearing 42 at the tip of an arm 41 fixed to the inlet fixing plate 20. 23
Is a well-known dehydration treatment agent charging hopper, and 24 is a dehydration treatment agent charging screw, the shaft tip of which projects from the opening 40 of the inlet fixing plate 20 and is supported by the bearing 45 at the tip of the arm 44 fixed to the inlet fixing plate 20. The motors 25, 26 provided on the base 2 are driven by belts 27, 28. Reference numeral 29 denotes an opening / closing lid of the rotary drum 1. Agitation blades 30 and 31 and screw blades 32 are fixed to the inner surface of the rotary drum 1.

Reference numeral 46 denotes a scraping plate arm whose base is fixed to the inlet fixing plate 20 and is arranged obliquely downward. At the tip thereof, the inlet side inner end surface peripheral portion 1a of the rotating drum 1 and the inlet side inside are arranged in the right direction of the arrow. Sides 47a and 47b that abut the peripheral portion 1b of the peripheral surface
A scraping plate 47 having a square shape is fixed.

During use, the vehicle A is moved to the sludge treatment plant, the stabilizing jack 51 attached to the lower surface of the chassis B of the vehicle body is rotated to the vertical position to fix the vehicle A, and the belt conveyor 52 of the belt conveyor 52 is provided under the discharge port 50. Position one end. Then, the sludge dewatering apparatus C is operated. The sludge charged from the sludge charging hopper 21 is continuously charged into the rotary drum 1 from the opening 40 of the inlet fixing plate 20 by the sludge charging screw 22 rotated by the motor 25, and the dehydration treatment agent charging hopper 2
The cement-type or lime-type dehydration treatment agent charged from 3 is rotated by the motor 26.
4 through the opening 40 of the inlet fixing plate 20 to the rotary drum 1
It is continuously thrown in.

Air is also sent in by a device (not shown). The rotary drum 1 is rotating in the right direction of the arrow. The sludge and the dehydrating agent that have fallen into the rotating drum 1 generate heat when they first meet and are in a state where they are most likely to adhere, and the inlet-side inner end surface peripheral portion 1a and the inlet-side inner peripheral surface corner peripheral portion 1 of the rotating drum 1
Although attached to b, the sides 47a and 47b of the scraping plate 47 are dropped from below into the scraping rotary drum 1. In this way, the sludge and the dehydrating agent are not deposited on the inlet inner end surface and the inner peripheral surface corner of the rotary drum 1.

The rotating drum 1 is driven by a motor 11 for 5-10
The motor rotates at r.p.m., is gradually sent forward by the screw blades 32 and drops on the gutter 13 sequentially, and is discharged from the discharge port 50 to the outside of the rotary drum 1 by the discharge screw 14 rotated by the motor 15. The discharged discharged product is transferred to a predetermined position by the belt conveyor 52.

[0012]

According to the present invention, a large number of screw blades are spirally arranged and fixed on the inner peripheral surface of a rotary drum, and a sludge charging port and a dehydration treating agent charging port are provided on an inlet fixing plate of the rotating drum. Discharge screw is installed on the outlet side, the arm base is fixed on the inlet side fixing plate, and the scraping plate is fixed on the arm tip.
Contact one side with the periphery of the inner end surface of the inlet side of the rotating drum.
The sludge dewatering device with the other side in contact with the peripheral portion of the inner peripheral surface is placed on the vehicle body chassis of the vehicle, the discharge port is located above the rear space of the vehicle chassis, and the discharge product is below the outlet. Since a transfer mechanism for transferring the water to a predetermined position is provided, the sludge and the dehydrating agent sent into the rotary drum first encounter each other to generate heat, and the scraping occurs when the most easily adhering state occurs. There is no adhesion and deposition on the inner end surface and the inner peripheral surface. Therefore, the mixture of sludge scraped off and the dehydration treating agent does not adhere to the inside of the rotary drum and can be smoothly stirred and conveyed.

Further, since the device of the present invention is of a mobile type, it is not necessary to move the device of the present invention to the place where sludge is discharged and separate the water as in the conventional case, and it is necessary to squeeze the water to treat this water. There is no problem, sludge can be agitated on the spot to form a dry discharge, and it can be maintained in a dry state without becoming muddy even if it is rained, which is convenient for storage and can be performed extremely efficiently.
