Description

[Detailed description of the invention]

[0001]

[Industrial application] The present invention is intended to collect sewage from wastewater discharged from factories or the like, or sewage (fiber etc.) from sewage from sewage, dewater and pack into bags. It relates to a dehydration unit.

[0002]

2. Description of the Related Art As shown in FIG. 7 , a dehydrator conventionally incorporated in a residue collecting and dewatering unit supplies a residue collected by a dust remover into a cylinder b having a large number of slit grooves a on its peripheral surface. It was compressed by pushing do the compression chamber d by a plunger c which is dehydrated, or as shown in FIG. 6, the hopper e
There is known a screw conveyor f provided therein, and the screw conveyor f is used to squeeze out moisture contained in the residue.

[0003]

However, in the former method, when the residue remaining in the cylinder b accumulates, the residue is pushed into a compression chamber d by a plunger c to compress and dehydrate, and the operation is intermittent. In addition to this, there is a disadvantage that the dehydrator becomes large.

[0004] Further, since both of them knead the residue in the compression chamber d or the hopper e, the residue becomes a lump and the specific gravity increases, making the subsequent processing difficult. There are problems such as residue generation and decay, and secondary odor is likely to be generated.

It is an object of the present invention to obtain such a trouble-free or residue collecting and dewatering unit.

[0006]

According to the present invention, in order to achieve the above object, a dewatering roller is formed by pressing a dewatering roller on a substantially horizontal conveyor belt stretched between rollers. The carrying-side end of the conveyor belt to be constituted is brought into contact with the screen surface of the screen-type dust remover, and the residue discharge portion of the screen-type dust remover faces the upper side of the carry-in side of the conveyor belt and the lower part of the discharge side of the conveyor belt. With the entrance opened and the residue storage bag waiting.

[0007]

In the residue collecting and dewatering unit having the above construction, if the residue is discharged from the residue discharge section of the screen type dust remover on the upper side of the conveyor belt constituting the dewatering machine, the conveyor belt is removed. The residue is compressed and dehydrated between the conveyor belt and the dewatering roller by the movement of, and then fits in the residue storage bag. In addition, even if the residue contains a hard material, the conveyor belt and the dewatering roller will not be forced by bending of the conveyor belt.

Further, the conveyor belt constituting the dewatering machine is brought into contact with the carrying end of the conveyor belt on the screen surface of the screen-type dust remover, so that the conveyor belt can be used as a scraper that adheres to the screen-type dust remover and scrapes off the residue. Function.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described with reference to the drawings. In the drawing, reference numeral 1 denotes a dewatering machine constituted by pressing a dewatering roller 2 on a substantially horizontal conveyor belt 1b stretched between a pair of left and right rollers 1a, 1a, 3 denotes a screen type dust remover, and 4 denotes a conveyor belt 1b. The residue storage bag which stands by with the entrance opened at the lower part of the discharge side is shown.

Referring to FIGS. 1 to 3 in detail, the conveyor belt 1b has a plurality of flat belts or V-belts stretched between the rollers 1a, 1a. The water squeezed between 2 and
The conveyor belt 1 passes between the flat belts or V-belts.
b into the water receiving tray 5 provided below.

The conveyor belt 1b is constantly tensioned by an intermediary of an elastic machine 6 such as an elastic spring between the bearing 1c of the roller 1a and the frame 1d, so that a residue is formed between the conveyor belt 1b and the dewatering roller 2. To produce a constant pressure force.

However, this is because the conveyor belt 1b itself has elasticity and the rollers 1a, 1a
The tension between the conveyor belt 1b and the dewatering roller 2 can also be generated by stretching between them.

Reference numeral 7 denotes a scraper for removing the dewatered residue on the conveyor belt 1b from the conveyor belt 1b.

The screen type dust remover 3 is provided with its lower part immersed in the sewage passage A, and the residue discharge section 3a at the upper end of the screen type dust remover 3 faces the upper side of the conveyor belt 1b on the carrying side. In addition, the carry-in side end of the conveyor belt 1b constituting the dehydrator 1 is brought into contact with the screen surface 3f.

To explain this further, the screen type dust remover 3 comprises a plurality of fixed screens 3c attached to a screen frame 3b and arranged in parallel at intervals in the vertical direction.
, And rollers 3d and 3d provided above and below the stationary screen 3c, respectively, and a rotating screen 3e composed of a number of belts extending between the rollers 3d. The stationary screen 3c constitutes the rotating screen 3e. It functions as a guide that supports the front side belt from behind.

Then, the upper roller 3d is directly connected to the motor 9 via the chain 8, and the rotating screen 3e is rotated to scrape the residue contained in the sewage flowing in the sewage passage A with the rotating screen 3e. I tried to fry.

The dehydrator 1 is also directly connected to the motor 9 via the chain 10 to be driven.

Numeral 11 designates a cover for covering the upper part of the screen type dust remover 3 and the dehydrator 1 so as to prevent the odor generated from the residue itself from being released to the outside,
The lower part of the conveyor belt 1b on the discharge side is a cylindrical chute 1
1a, the entrance of the residue bag 4 was tied around the lower part of the chute 11a, and the residue bag 4 was exposed to the lower part of the discharge side of the conveyor belt 1b.

In the dehydrator 1, as shown in FIG. 4 , a conveyor belt 1b is stretched between a plurality of rollers 1a, 1a, and on the conveyor belt 1b extending between two rollers 1a, 1a. If the contact area between the conveyor belt 1b and the dewatering roller 2 is increased by pressing the dewatering roller 2 on the sheet, the efficiency of pressing the residue can be increased.

In FIGS. 4 and 5 , reference numeral 12 denotes a roll for tensioning the conveyor belt 1b.
Reference numeral 2 denotes a structure in which rolls are attached to both ends of the swing arm 12a, and a spring 12b attached to the other end of the swing arm 12a is brought into pressure contact with the conveyor belt 1b. The roll 1
2 is pressed against the conveyor belt 1b and the roller 12 is directly connected to the motor 9 to be driven, so that the roll 12 functions as a scraper that adheres to the conveyor belt 1b and removes residue. I do.

Advantages of the Invention The residue collecting and dewatering unit having the above-described structure has the following effects. If the residue is discharged from the residue discharge part of the screen type dust remover on the upper side of the conveyor belt constituting the dewatering machine, the residue is transferred between the conveyor belt and the dewatering roller by the movement of the conveyor belt. The dewatering machine is composed of a conveyor belt and a dewatering roller 2 and has a very simple structure. The residue is depressed and dewatered between the conveyor belt and the dewatering roller. After dehydration, the residue is separated and fits in the residue storage bag, which has the advantage of reducing the apparent specific gravity of the entire bag when packed and making it easier to take it out of the field. Even if the conveyor belt is deflected, the conveyor belt and the dewatering roller will not be forced by bending of the conveyor belt. Moreover, since the conveyor belt is in contact with the screen surface of the screen type dust remover, the conveyor belt also functions as a scraper for the residue adhering to the screen surface and scrapes the residue adhering to the screen surface. It can be dewatered and bagged together with the sewage discharged from the sewage discharge section of the screen type dust remover.
