Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for incineration, etc., while sequentially stocking bags in which quantitatively packed screen residues that have been washed and dehydrated after being scraped and collected from waterways such as sewage treatment plants and pumping stations. It is about.

[0002]

2. Description of the Related Art In a sewage treatment plant, a pumping station, etc., solid matter mixed with sewage, so-called screen residue, is separated from sewage, and the solid matter and sewage are treated separately. This solid matter is generally called a screen residue, and since it is scraped and collected from wastewater with a dust remover, it also contains a lot of uncrushed waste such as human feces, and has a very high water content. It has a bad odor and cannot be dumped, incinerated, or carried to the dumping position in this state. For this reason, the collected screen residue is dehydrated to the required water content. As a dehydrator for this screen residue
7-43049 and JP-A-1-117118. Further, it is processed by the method shown in FIG.

[0003]

However, even if the screen residue is dehydrated and transported by the piston action of pressurized dehydration in the sealed transport pipe, it is stored in the hopper and then loaded on a truck or the like to be incinerated or dumped. Since it is necessary to transport it to a place, when it is loaded onto this truck or the like, the dehydrated screen residue is also scattered into the atmosphere because it is open to the atmosphere, or a foul odor is scattered in all directions. In order to prevent this, a method of bagging and processing has been proposed. However, this method does not provide a stockyard close to the bagging station, and therefore, it is necessary to carry the dewatering screen immediately after bagging or to carry it to another place. Therefore, in the conventional method, it is troublesome to carry out and stock after bagging.

According to the present invention, the screen residue recovered from a sewage treatment plant is crushed and washed, dehydrated, and then packed in a fixed amount in a bag, which is sequentially stocked and carried out as necessary for treatment. With the goal.

[0005]

The present invention has been made to achieve the above object and comprises a bagging station for filling a bag with a required amount of dehydrated screen residue and a stockyard for stocking the bagging station. The screen residue packed in the adjoining bagging station is transferred to and stored in the adjacent stockyard empty address by an automatic hoist, and the stockyard is equipped with a load detection means for each address to sequentially open the empty addresses. The gist is to store the bags and transport them from this stockyard to the treatment plant if necessary.

[0006]

Operation: The screen residue that has been washed and dehydrated is folded into the bag holding frame on the turntable with its mouth folded back and put into a predetermined bag set in an open state. At this time, since the bag is supported by the bag holding frame on the turntable, the bag does not fall down and is stable, and the opening is surely performed, so that a predetermined amount of screen dust is surely filled in the bag. it can. Next, the loop-shaped fastening string inserted through the bag mouth portion is pulled to close the bag mouth portion, and a predetermined bag is packed. Then, the stockyard adjacent to this bagging station is moved using a hoist or the like and stored. A lot number is set in advance in this stockyard, the empty lot number is confirmed, and the bag is transported and secured to the empty lot number. Then, this stockyard is loaded onto a truck or the like and transported to an incinerator or the like, and the next bag is transported and stored again to an empty lot number. This eliminates the need for a conventional conveyor for transporting dewatering screen residue, a hopper for temporarily storing the same, and a skip hoist for transportation, and moreover, from bagging to storage, it can be consistently and hygienically performed.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below based on the illustrated embodiments. The uncleaned human waste such as human feces is contained in the screen residue that is scraped up and collected from a waterway such as a sewage treatment plant or a pumping station by a dust remover.To remove it, it is either continuous or intermittent. It is supplied to the crushing and washing apparatus A through a conveyor. Then, the crushing and washing device A crushes and cleans the filth, and after removing the filth, it is supplied to the pressure dehydrator B disposed below this. The crushing washing dehydrator A is disposed at a lower position of the upper end of the conveyor C, and is also disposed above the pressure dehydrator B so as to serve as a hopper so that the screen residue is easily charged.

Various devices can be used as the crushing and washing device A, but the one shown in the drawing has a press plate 2 and a roller 3 which are opposed to each other in the casing 1, and the roller 3 is rotated to rotate the press plate 2 Is brought into pressure contact with the roller 3 side at a required pressure, and a cleaning nozzle 4 for spraying cleaning water at a required high pressure toward the outer peripheral surface of the roller or between the roller and the press plate is provided.

As a result, the recovery screen residue introduced into the casing 1 from the conveyor C falls between the press plate 2 and the roller 3, and the rotation of the roller 3 and the pressing force of the press plate 2 to the roller side. As a result, the uncrushed filth of the screen residue is crushed and washed with washing water sprayed at high pressure.

Then, the screen residue supplied from the crushing and washing device is then squeezed and dehydrated. In the pressurized dehydrator B, a piston 41 of a hydraulic cylinder is provided in a dehydrating cylinder 42, and when the cylinder is operated, the piston 41 advances and retracts in the cylindrical dehydrating cylinder 42 and is sequentially supplied from the crushing and cleaning device A. The screen residue is intermittently squeezed and dehydrated through the drainage hole of the dehydration cylinder.

The conveying pipe line 5 is connected to a dehydrating device having a hydraulic piston 41, and a chute 6 having a measuring section is arranged at the tip of the conveying pipe line 5 so that a desired internal volume is obtained. And open and close the shutter 6 at the bottom (bottom).
1 is provided, the shutter is opened, and the dehydration screen residue is charged and supplied from the chute 6 into the bag 7 on the bagging table, for example, the turntable 8 to carry out the bag packing.

The empty bags 7 having a required size are arranged on the turntable 8 with their mouths open at predetermined intervals, and are stably supported so that the bags do not fall. Then, in a state where the empty bag 7 is unfolded, the screen residue is introduced from the upper position through the chute 6 provided at the tip of the transfer conduit. Two endless mouth fastening strings L, L are inserted into the bag 7 by sewing the outer periphery of the mouth of the bag 7 for filling the screen residue.

Further, a stockyard S2 for stocking a required number of filled bags is arranged adjacent to a bagging station S1 for dehydration and bagging of the screen residue, and a stockyard is provided on the turntable of the bagging station S1. An automatic hoist 10 that moves along the entire length is provided. This automatic hoist 10 has a hoist rail 11 having a length over the entire length of the stock yard arranged above the turntable, supports the hoist 12 along the hoist rail 11 so that the hoist 12 can travel, and has an automatic hook on the hoist. A hoist 13 is provided so that operations such as traveling of the hoist, raising and lowering, opening and closing of hooks can be performed by the operation panel 14 provided at the bagging station side or at a predetermined position.

The stockyard S2 is filled with a required amount of dewatering screen residue, and the space necessary for placing one bag with a closed mouth is set as the first base, and this is used as a row or a plurality of rows for hoist rails. Are arranged in the longitudinal direction of each of the addresses, and the presence detection means K is provided for each address so as to detect the vacancy / actual value of each address, and the hoist 12 is stopped upward facing each address. To do so, hoist stopping means, for example, a SW such as a limit switch is provided.

Therefore, the bag 7 placed on the turntable
After filling the required amount of dewatering screen residue into the inside and closing the mouth, the automatic hook 13 of the hoist 12 is lowered, and the fastening string L of the bag or the hoisting string attached to the bag is hooked and lifted up, along the rail. Move the hoist above the stockyard. Then, the vacant address of the stockyard is determined by the presence detection means K, and the bag is hung on the vacant ground. By repeating this operation in sequence, the bags of screen residue packed on the turntable are lifted one after another, transported, and stored or stored in the stockyard S2. When the bag is transported to an incinerator or the like, it is hoisted again and loaded on a truck or the like. In the opened lot number, the next bag is stored again in the same manner.

The embodiment shown in FIG. 2 shows a method for collectively processing screen residues generated in large and small treatment plants, pump stations, etc. scattered over a wide area. Large-scale sewage treatment plants are equipped with large-scale cleaning and dehydration bagging devices, medium-scale treatment plants and pumping stations are equipped with simple cleaning dehydration bagging devices, and small-scale facilities are equipped with compact screen processing devices. The screen residue generated is packed and stored as described above, and it is possible to collect and dispose of the screen residue in a hygienic and efficient manner by performing intensive processing after patrol collection in a collection truck.
