Description

[Detailed explanation of the invention] This invention is a water intake screen for a dam reservoir,
This invention relates to a roller press for dewatering and reducing the bulk of screen sludge collected at pump stations, sewage treatment plants, and other bulky wastes with relatively high moisture content.

2. Description of the Related Art Conventionally, roller presses have been widely used in which waste is dehydrated by passing it between two rollers arranged above and below. However, if a relatively large stone, piece of wood, etc. gets caught between the rollers, the machine may be damaged, so various means have been devised to prevent this. However, conventional damage prevention measures
The problem is that the structure is complex and prone to failure.

In view of the current situation as described above, the purpose of this invention is to obtain a roller press with a simple structure and a high dewatering rate, which can prevent breakage and the like.

In other words, the roller press according to this invention is
An upper roller supported via a horizontal shaft so as to be movable up and down guided by guide frames fixed to both sides of the main body in a backward-slanting manner; a garbage input port disposed above the front part of the upper roller; The lower roller is supported via a horizontal shaft located behind and below the upper roller axis, and the upper end is located in front of the garbage inlet and the lower end rotates concentrically with the lower roll horizontal shaft. It consists of a curved press plate that is freely supported and supported by a hydraulic cylinder device on a pedestal, and a garbage discharge port provided at the rear of the lower roller, and the horizontal axis of the upper roller is constantly urged downward by a spring. It is configured as follows.

In this specification, "front" refers to the garbage input side, and "rear" refers to the garbage discharge side.

According to the roller press of this invention, the garbage thrown into the press plate from the input port is pushed downward by the upper roller, is squeezed between the press plate and dehydrated, and is then transferred to the lower roller. After the waste is dehydrated and reduced in bulk, it is dropped from the outlet through a discharge chute onto a waste receiving conveyor or the like and transported to a predetermined location. The distance between the press plate and the upper roller is adjusted using a hydraulic cylinder device for supporting the upper roller and/or the hydraulic cylinder device for supporting the press plate, and the distance between the upper roller and the lower roller is adjusted using the hydraulic cylinder device for supporting the upper roller. This is done by a cylinder device, and if a relatively large stone or piece of wood gets mixed in between the upper and lower rollers and the press plate, the upper roller will be pushed up against the spring force, and the stone or piece of wood will pass between the rollers.
