V Utility model registration for a briquetting press type 600 VH.

? ■ - Briquetting presses for waste materials of all kinds, such as schnitzel,

f Shavings, flour, peel, dust etc. have been known for a long time and are in

£ use. Such briquetting presses are used in rough working conditions

-; very often high wear due to abrasive contamination in the pressed material

' exposed. iy

The aim of the invention is to reduce the effects of this wear and tear

■ to reduce the economic efficiency of the briquetting process }. is significantly impaired.

fr Another object of the invention is to make the Regelbarkei'- of the system, '' as a function of pressing material and machine capacity so,

that an acceptable hourly output can be achieved with as trouble-free operation as possible.

The individual elements of the briquetting press of the type described below, which are particularly exposed to wear, have been designed in this way

·? designed that they have a high wear resistance and / or

;; can be easily exchanged.

The control of the machine was made using a programmable

■ Control system designed so that all functions during start-up and Shutdown are secured with each other, and that a sensitive reaction of the press system (tongs, press chamber, feed) to the different operating conditions in the briquetting of uneven materials in varying amounts is made possible.

Description:

; The press slide (2) is in a fine, stable steel housing (1)

moves a crank mechanism (3). In the press slide (2) sits the press piston (4), which dips into the press chamber (5) and there compresses the material to be pressed. The press chamber (5) sits on the press housing (6), which is separated from the steel housing (1) by a separation chamber (8) from the crankcase. Seated between the separation chamber (8) and the press housing (6) a special seal (9) that seals the piston all around.

The material to be pressed is conveyed via a horizontal screw (10) and the vertical screw (11) into the press housing, from where it is pressed by the press piston (4) through the press chamber (5) and thus compressed that briquettes are created. The compression chamber (5) consists of a compression ring (5a) and a cone (5b), both of which are cooled via the cooling sleeve (12) can be.

Following the pressing chamber (5) sits the pressing tongs (13), which serves to hold the pressed part (briquette) so firmly that it does not fly out of the press chamber with every press blow and thereby destroy it will.

The pliers effect is created by the fact that the upper part of the crimping pliers (14) is adjusted against the lower part (13) by a hydraulic cylinder (15) with adjustable force. In the upper (14) and lower part of the bale chamber (13) there are wear inserts (16 + 17) that can be easily replaced.

The movement of the hydraulic cylinder (15) is effected via the electrohydraulic control system in such a way that no overload can occur and the press can be started up and stopped without problems is made possible.

The control reacts to changes in the material to be pressed and in the filling quantity. Set values ensure that the tongs move in good time Material shortage or excess.

The desired functional sequences of the entire press system at the start or shutdowns can be preprogrammed, so that starting up is easy and stopping is enabled.

Claims (1)

New version of the protection claims Claim 1 Briquetting press consisting of steel housing (1) with press slide (2) and crank drive (3), which moves the plunger (4) so that it forms briquettes from the loose material to be pressed in the pressing chamber (S), characterized in that the in the pressing carriage (2) used plunger (4) is easily exchangeable and a pressed material-specific Has tip. The plunger (4) has a stepped diameter and sits with its thicker part in the press slide (2), where it curch a retaining ring and screws is held. Claim 2 Briquetting press according to claim (1) with cooled pressing tongs (13) thereby characterized that the crimping pliers easily replaceable wear inserts (16) and (17). The wear inserts (16) and (17) are on both sides Flat milling of a pipe piece made, which has a collar at one end. This collar prevents the wear inserts from moving axially secured. Claim 3 Briquetting press according to claim (1) and / or (2), characterized in that the Preßkolbeü (4) to the press housing (6) through a one-sided split special seal (9) sealed> * ird. Claim 4 Briquetting press according to one or the claims (1 - 3), characterized in that that a gear pump is attached directly to the press, which is electromotive is driven. A forced filter and a manometer with an adjustable pressure switch are built into the lubrication circuit directly on the gear pump. Claim 5 Briquetting press according to one of the claims (1 - 4), characterized in that that it has a feed system, which consists of horizontal (10) and vertical screw (11), which have variable speed drives. Claim 6 Briquetting press according to one or the claims (1 - 5), characterized in that which the crimping pliers (14) has a hydraulic pressure cylinder.
