2. Description of the Related Art In a sewage treatment plant, a pumping station, etc., solids mixed in sewage, so-called screen residues, are separated from sewage, and the solids and sewage are individually treated. This solid matter is generally called a screen residue, and is collected from the sewage by being scooped and collected by a dust remover.Therefore, it contains a lot of uncrushed matter such as human waste, and has a very high water content. In this state, the odor is too bad to be dumped, incinerated, or carried out to the dumping position.
For this reason, the recovered screen residue is dehydrated to a required moisture content after washing.

[0003]

However, since the screen residue must be washed and dehydrated, loaded on a truck or the like, and transported to an incineration plant or a dumping site, the screen residue that has been dehydrated during loading and transporting to the truck or the like is required. Since they are also open to the atmosphere, they may scatter or foul odors may be scattered in all directions. In order to prevent this, a method of packing and processing has been proposed. However, in this method, a stock yard cannot be provided in the vicinity of the bagging station. Therefore, since the stock yard is suspended and transferred one by one using a crane, it takes time and effort to carry out and stock the bag. I have.

[0004] The present invention is intended to crush, wash, and dehydrate a screen residue collected from a sewage treatment plant and the like, pack it in a fixed amount, and then sequentially and quickly transfer it from a bagging station to a conveyor. It is an object of the present invention to provide a device for transferring a bagged screen residue.

[0005]

In order to achieve the above-mentioned object, a transfer apparatus for bagged screen residue according to the present invention comprises a bagging station for filling a required amount of dehydrated screen residue into a bag, and a conveying station for transporting the same. Is a transfer device for the bagged screen residue, which is installed between the conveyor and the bagging station, and automatically transfers the bag filled with the screen residue dehydrated at the bagging station onto the conveyor. And an elevating frame that moves up and down along the body frame, and slides horizontally along a slide rail formed on the elevating frame,
A slide cart having a horizontal fork formed thereon, and two guide plates suspended from the distal end side and the base end side of the slide rail, wherein the main body frame is turned, the lift frame is raised and lowered, and a slide cart is formed. The gist of the present invention is that the bag packed with the screen residue dehydrated at the bag filling station is automatically transferred onto the conveyor by the combination operation of the sliding operations.

[0006]

In the bagging screen residue transfer device, the screen residue dehydrated at the bagging station is packed at the bagging station by a combination of turning of the main body frame, raising and lowering of the elevating frame, and sliding of the slide cart forming the fork. Bags can be automatically transferred onto a conveyor. At this time, by lowering the elevating frame, two guide plates vertically suspended from the distal end side and the proximal end side of the slide rail formed on the elevating frame move the front and rear of the bag filled with screen residue (sliding of the slide cart). To prevent the bag from overturning, slide the slide cart, and transfer it onto the fork while shaping the bag with a fork formed on the slide cart. With the bag on the fork, raise the lifting frame,
By rotating the main body frame, the bag is moved onto the conveyor, and the bag is moved by sandwiching the front and rear of the bag on the fork (in the sliding direction of the slide cart) between the two guide plates. While preventing, slide the slide cart to pull out the fork and transfer the bags onto the conveyor.
