Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for surely filling a bag with screen residue that has been collected and dehydrated at a sewage treatment plant, a pump station, or the like.

[0002]

2. Description of the Related Art In a sewage treatment plant, a pumping plant, etc., solid matter contained in wastewater is separated from wastewater, and the solid matter and wastewater are treated separately. This solid is generally called a screen residue, and since it is scraped and collected from wastewater with a dust remover, the water content is also extremely high,
In this state, it cannot be dumped, incinerated, or carried out to the dumping position. For this reason, the collected screen residue is dehydrated to the required water content and loaded directly onto the truck.
They are either transported to the incineration site or the dump site, or packed in a bag for processing.

[0003]

When the bag is filled with the dewatering screen residue, the bag held in an open state is set below the charging hopper and the dewatering screen is dropped from the hopper. For this reason, there is a space between the lower end of the hopper and the bag opening, and the falling screen residue may stick out of the bag opening or the bag mouth may be pushed into the bag by this charging screen to ensure reliable filling. Sometimes you can't. Further, during filling, there is a defect that dust is scattered from the gap between the hopper and the bag mouth portion, or odor is scattered to the surroundings.

An object of the present invention is to equip a lower part of a charging hopper with an ascending / descending hood, and press the upper end of the bag mouth with a lower end of the descending hood to reliably fill the bag.

[0005]

SUMMARY OF THE INVENTION The present invention has been made to achieve the above object, and a hood is supported on a guide rail provided on an outer surface of a feeding hopper via a guide roller. The hood is moved up and down through a lifting mechanism that uses a cylinder and a lever link, and when the bag is held in an open state by the bag holding frame at the lower position of the input hopper, the lower end of the hood is lowered and the bag is opened by the bag holding frame. The gist is that the dehydration screen residue can be reliably put into the bag by sandwiching the part.

[0006]

[Function] In the hopper that fills the bag with dehydrated screen residue,
With the hood that can be raised and lowered, the bag held in the open state by the bag holding frame is set at the lower position of the loading hopper, and then the hood is lowered, and the upper surface of the bag mouth is held by the bag holding frame at the lower end of the hood. Hold by pressing. As a result, the charging hopper and bag mouth are covered with a hood to eliminate gaps,
Prevents dust and odor from scattering when filling the bag with the dehydration screen. At the same time, since the bag mouth is pressed and sandwiched, the bag mouth is prevented from being pushed into the bag by the charging screen residue, and the screen residue can be reliably charged and filled.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A bag filling device for dehydrated screen residue according to the present invention will be described below with reference to the illustrated embodiment. Since the screen residue (dust) that is scraped up from the sewage treatment plant / pump station and the like has a high water content, it is dehydrated by the dehydrator 1 to a water content suitable for incineration or disposal. The dewatering screen is conveyed to the feeding hopper 3 via the conveying means 2 such as a belt conveyor and a conveying duct.

A turntable 4 is arranged below the input hopper 3 so as to rotate intermittently, and bag holding frames 5 are arranged at predetermined intervals on the turntable to dehydrate the bag. In addition to making it possible to input and fill a fixed amount of screen residue, the intermittent rotation of this turntable is performed with a pitch of the bag holding frames as one pitch, and the bag holding frame faces the lower part of the input hopper at the fixed position of the turntable stop. Do as you do.

A hood device 7 is provided below the charging hopper 3 either directly or through a weighing device 6. In the illustrated embodiment, a weighing device 6 with a gate is provided below the charging hopper so that the amount of dewatering screen residue charged into the bag according to the size of the bag becomes a predetermined amount.

The hood device 7 is supported so as to be able to move up and down along guide rails 8 and 8 provided on the outer surface of the charging hopper 3 or the weighing device 6. A cylinder provided on the frame of the throw-in hopper 3, the upper ends of the levers 11, 11 being pivotally attached to the brackets 10, 10 protruding from the frame so as not to interfere with the lifting and lowering of the hood 9 for covering the bag B, and provided on the frame. 12
The rod 12L of is attached to a part of the lever 11,
The lower ends of the levers 11 and 11 have links 13 and 13 respectively.
And the other end of the link 13 is supported by the hood 9. Then, a guide roller 14 is provided at the lower end of the link 13 so as to be fitted to the guide rail 8.

The hood 9 has a cylindrical shape with a lid, and the feeding hopper 3 penetrates into the hood lid.
The hood 9 moves up and down along the guide rails 8 by operating the cylinder 12, and a tubular hood body 9b having a required length is integrally provided on the lower surface of the outer periphery of the lid 9a. Be approximately equal to the diameter of. On the lower end surface of the hood main body 9b, the bag holding frame 5 and the bag mouth portion are clamped with a predetermined elastic force so that the bag is not slipped so as to be easily clamped from above and below.
A soft resin or the like is provided.

The weighing device 6 has a cylindrical main body 6a and a gate 6 provided at the lower end of the main body so as to be openable and closable.
b and opening / closing means 6c such as a cylinder for opening / closing this gate
The entire weighing device 6 is housed in the hood 9, and the gate 6b opens and closes inside the hood.

A method for filling the bag B with the dehydrated screen residue quantitatively in the apparatus constructed as described above will be described below.

When the dewatering screen residue reaches the charging hopper 3 via the conveying means 2, it is supplied from the charging hopper 3 into the weighing device 6. This weighing device 6 is always a gate 6b
Is closed, and the bag holding frame 5 is placed at a position below the input hopper 3.
The gate 6b is opened when the predetermined bag B is held in the open state and stopped, and when the dehydration screen residue in the weighing device reaches a predetermined amount. At this time, the hood device 7 descends, and the bag mouth is pressed and sandwiched by the lower end surface of the hood body, so that a certain amount of screen residue is surely charged and filled in the bag.

The hood device 7 stands by at the raised position,
The descent is performed after the bag B held by the bag holding frame stops at a fixed position. With the rod 12L protruding when the cylinder 12 is operated, the lever 11 is guided to the guide rail 8 from the rising standby position and swings downward as shown in FIG. Since the hood 9 is provided on the lever 11 via the link 12, the hood descends so as to sandwich the bag mouth portion and to cover between the charging hopper and the bag mouth portion.

After a fixed amount of the screen residue is put into the bag, the hood is guided by the guide rails to be lifted by the reoperation of the cylinder 12, and stopped at the standby position. This operation is repeated.

[0017]

According to the bag filling apparatus for the dehydration screen residue of the present invention, the hood is supported on the guide rail provided on the outer surface of the charging hopper through the guide roller, and the tubular hood is formed by the cylinder and the lever link. When the bag is lifted by the lifting means and comes to the bag held in the opening state by the bag holding frame at the lower position of the input hopper, the opening is sandwiched by the lower end of the hood and the bag holding frame, and the dehydration screen residue is retained. Since it is designed to be put into the bag, it is possible to reliably add and fill a fixed amount of screen residue without pushing the bag mouth into the bag, and to prevent dust and odor from scattering.
