The present invention relates to a solid material transfer processing device, and more particularly, a transfer hopper or a second and third processing process facility for storing a feed material introduced in variously installed transfer pipes regardless of a transport distance such as horizontal, vertical, curved, up, down, left and right. The conveying plate which is discharged through the outlet after being transported to is welded to the chain with two points, and is installed with a gap on the inner circumferential surface of the pipe, and a roller is installed on the curved portion of the pipe to prevent the wear of the chain and the pipe. The present invention relates to a solids transfer processing device that reduces the pressure and increases durability and facilitates maintenance.

Normally, household wastewater generated from households and livestock farms, and industrial wastewater generated from factories are unrefined and discharged into the sea or rivers, resulting in water pollution. Thus, the wastewater is purified through a sewage treatment plant installed at a certain place. It will be discharged.

In the wastewater treatment facility of the sewage treatment plant, a sludge removal process of separating and removing various sludges (precipitates) contained in the sewage from water is performed. The amount of sludge treated in this way is expected to increase every year due to the strengthening of water pollution standards, increase of sewage treatment rate, and deterioration of water quality of water supply.

In addition, the solids removal performed in the wastewater treatment plant introduces the wastewater filtered through the screen into the sedimentation chamber to remove impurities from the sewage inlet. Then, various sediments and contaminants are included at the bottom of the precipitation chamber to continuously circulate the sewage.

The various sediments and contaminants moved in this way are lifted up using a basket conveyor (acupuncture lifter), which are transferred to the transport container or the storage hopper installed at a predetermined place by taking over the next transfer means.

However, the transfer means taking over the sediment and sediment raised by using the screen and the basket conveyor is to transport the sludge in conjunction with a plurality of belt conveyors, which has a closed end causing the following problems.

In the case of using the belt conveyor, there is a problem in that the conveyed materials are exposed to the outside, which greatly deteriorates the working environment due to the odor generated from the contaminants and the needles.

Since the belt conveyor can only be transported in a straight state, there are problems that a conveyor of several stages is required in order to transport contaminants and sediment to an external discharge location. Accordingly, there is a problem that the transport structure of the sludge becomes very complicated.

In addition, the manufacturing and installation of the conveyor apparatus is difficult, which causes a problem of increasing the manufacturing cost.

In addition, since the conveyors of various stages are installed, there is a problem in that maintenance is difficult as equipment is enlarged and several driving units are installed.

As it is enlarged by the conveyors of the various stages, the occupancy area of the installed apparatus is increased, and maintenance is difficult, and a huge investment cost is required.

Patent registration No. 10-0331894 'Sewage sludge conveying apparatus' is known that overcomes some of the problems presented in the prior art as described above, the conventional, sewage conveying apparatus 2 is a feed material that is introduced into the pipeline (4) Although the conveying plate 6 for conveying the feed plate 6 is configured to be conveyed to a specific place by the driving force of the driving device 8 along the pipeline 4 by the chain 5, the outer portion of the conveying plate 6 is formed by the chain ( 5) has a gap (G) with the outer circumferential surface in the pipe, there was a problem that the transport of the sludge, which is the conveyed material is not precisely made.

When connecting according to the installation of the pipeline 4, the bolt holes formed in the flange 10 of the pipe to be aligned with each other by adjusting the posture of the inlet 12 while matching the bolt holes do not match when connecting There was a problem with discomfort such as or not.

In addition, the conveying plate 6 is installed at the point of contact with the standing chain 5 so that the sludge, which is the conveyed material, is not properly transferred as the sludge is conveyed with the pipe inner diameter and the gap G when the sludge is conveyed. There is a problem in that the conveying efficiency is lowered and conveyed while flowing.

The conventional transfer plate has a problem that, as one point is mounted on the chain, as well as the unstable state, the welded portion is dropped and broken in the chain sprocket, corner.

In addition, there is a problem that the maintenance cost is excessively consumed by replacing all of the chain including the transfer plate during maintenance due to the wear of the chain.

As described above, when the chain 5 moves in the orbital state inside the pipeline 4 under the driving force of the chain sprocket, the corner portion angle at the U turn portion or corner portion of the pipeline is only about 45 °. In case of 90 °, two 45 ° had to be attached and attached, and when the tension was applied to the chain (5) by installing the liner (18) adjusted by the adjusting bolt (16) by providing the corner housing (14). , The liner 18 is to be moved by sliding, so the wear rate of the liner is severe, and there is a problem that excessive cost is required for maintenance costs such as frequent replacement.

In addition, when the liner is not replaced in a timely manner, damage may occur to the pipe itself, resulting in enormous material loss costs.

It is proposed to solve the problems of the prior art as described above, an object of the present invention is to store the feeds put into the transfer pipes installed in various ways irrespective of the transfer distance, such as horizontal, vertical, curved, up, down, left and right, the storage hopper or the second The conveying plate which is discharged through the discharge port after being transported to the processing process facility of 3 is welded to the chain with two points, and is installed with a gap on the inner circumferential surface of the pipe.
