DOUBLE DRUM PRESS FOR SEPARATION OF LIQUID FROM SOLID

The device according to the invention is separated by squeezing a liquid bound to a solid. In addition to compression for incineration, in the future, for reasons of nature conservation, too much solids will have to be removed from landfills.

In existing drum presses, the compression gap between the drums changes when a constant compression pressure is used as the quality of the material to be compressed or the amount of feed changes, and this requires expensive loading equipment.

10 Keeping the amount of feed in current drum presses equivalent to the desired press capacity requires cumbersome and expensive monitoring equipment for the press.

In some drum presses, when the feed has stopped rolling, the press drum rolls the second drum when no material to be pressed enters between the drums. Over time, rolling causes damage to the drum surfaces and clogging of the holes.

In most drum presses, the material to be pressed passes through the press point of the press only once, with the exception of the Bark Master press-20 according to Finnish patent No. 62330, where the pressing takes place in the so-called monikertapuristuksena.

The feed to the drum presses takes place by a separate feed and separate discharge device, except in the press according to patent FI-62330, where the press flows out of the press. The presses are also equipped with scrapers which consume considerable power.

The solution according to the invention for drum presses provides an improvement on the above-mentioned drawbacks. The structure of the press is based on its operating principle that its pressing space is always in use full of the material to be pressed and the pressing gap 30 corresponds to the max. compression capacity at a given compression load regardless of the amount of material to be compressed. The compression gap only changes as the quality of the material to be compressed changes. The loading devices come in a simple manner, or can be made with a fixed pu-35 cross slot when the material to be pressed is of uniform quality.

The minimum compression gap must be close to the max. capacity compression gap so that rolling between drums 2 68563 does not occur and non-crushing hard parts about the size of the compression gap will not damage or stop the press. The press is not prone to clogging, because the material to be pressed is fed to the press 5 and removed from the press on the same conveyor, whereby the feed exceeding the capacity of the press passes the press without being pressed in the press but mixing with the press. If the feed to the press is less than the max. the compression capacity takes place for the compression-10 material so-called. multiple compression. Only the amount of material to be pressed corresponding to the feed is removed from the press. The power requirement of the press is not substantially higher than that of other drum presses, although the amount of material corresponding to the full capacity of the press always passes through the press gap, as the power requirement in drum presses is

In the following, the invention will be explained in detail with reference to the accompanying drawings.

Figure 1 shows a side view of the press. Figure 2 shows a cross section.

The drums (1,2) of the press nested around the various centers of the press are mounted on the body of the press. Si drum (2) made of axle pins, bearing housings, e.g. in the bearing disc slots, movable with load cylinders when using the inner drum as a load drum. The outdoor pump is then supported by support frames that rotate on bogie gears mounted on the run-30. If the press is made in such a way that the compression gap (D) between the drums (1,2) is constant, the bearing housings of the inner drum are fixed without, with room for movement, bearing the outer drum as above. When the outer drum (1) is used as a load drum, it is mounted on a separate body hinged to the main body, which is lifted towards the inner drum (2) by a load device. The outer drum (1) is equipped with non-rotating end plates (3,4). Both drums (1, 2) of the press can be equipped with a drive device, one of which acts as the main drive device (5) and the other as an auxiliary drive device (6), ensuring the passage of cumbersome substances into the press jaw. The material to be compressed is fed to the press at one end (A) and removed at the other end (B). The supply of the press, the transfer of the material to be pressed in the press and the removal from the press take place by one of the same conveyors (7) mounted between the drums (1,2) and passing through the press. At the same time, the conveyor can also act as a kaa-10 vibration for the drum press surfaces. Inside the conveyor chute press, the drums (1,2) and the material to be pressed in the pressing chamber (C) form. Due to the structure, as soon as the material to be pressed enters the inside of the end plate (3) of the press, it starts to flow into the pressing space (C) according to how the press is swallowed. The material to be pressed is partially mixed with the already pressed material that comes from the press to the conveyor (7) * When the amount of feed is max. less than capacity occurs in the so-called. multiple compression for the material to be compressed.

Claims (1)

* 68563 CLAIMS A double drum press for separating liquid from a solid in which the material to be pressed is nested between drums (1,2) rotating around different centers in a compression space (C) from one end of the press (a) and after compression is removed from the opposite end (Θ). Compressed la (C) is always full of material to be compressed when the press is running. The press drums (1,2) can be either both routed or just one of the drums. The outer drum (1) is equipped with non-rotating end plates (3, A). The second drum of the press 10 is equipped with a main drive device (5) which normally rotates both drums (1,2) via the pressed material but if it is necessary to ensure that the pressed material enters the press slot (O) with difficult materials. than the main drive. The compression load takes place on either drum or on drums (1,2) permanently mounted on a uniform material to be compressed, the compression gap (D) being constant. The press is characterized in that the ai-20 to be pressed is fed into the press, moved in the press and removed from the press by a single conveyor (7) passing through the press mounted between the drums (1,2) which can also act at the same time.
