Definitions
- the invention relates to a housing of a horizontal solid-bowl screw centrifuge.
- the object of the invention is to design the housing of a horizontal full-shell screw centrifuge in two shells and to ensure simple assembly of the inner shell.
- the housing has a lower, almost over the entire length of the housing opening for a tubular inner shell, which is provided with connections extending radially to the axis of rotation of the screw centrifuge for the discharge of solids and liquids and the front side in the outer housing is definable.
- the two-shell construction advantageously results in a use-related effort in each case through a sensible division of tasks for the outer housing and the inner shell.
- the outer housing can advantageously be made in one piece from cast iron, as a result of which a high level of structural strength for good machine dynamics is achieved in a simple manner.
- the tubular inner shell can be made relatively easily from product related. Material.
- the outer surface of the inner shell is not a surface in contact with the product or a visible surface, which means that the construction is simple and the quality of the outer weld seams is low.
- Another not inconsiderable advantage of this two-shell design is a significant reduction in noise emissions.
- the tubular inner shell is inserted through the lower assembly opening into the outer housing in such a way that the longitudinal axis of the inner shell runs parallel to the longitudinal axis of the outer housing during this assembly movement.
- the tubular inner shell is moved in the axial direction to an end face of the outer housing, on which the tubular inner shell, e.g. is attached by screws.
- An inner ring inserted into the inside of the tubular inner shell in the inner shell is screwed to the associated end face of the outer housing after the other end face has been fixed on the outer housing, so that the end face of the inner shell is supported on this inner ring and the inner shell under different temperature loads compensates for this movement Can make inner ring.
- the tubular inner shell into which the rotor and the gear unit of the screw centrifuge are inserted from one end of the outer housing and is mounted in the front bearing caps, has a sound-absorbing effect during operation of the screw centrifuge and also forms a structural unit with the connections for the discharge of solids and liquids.
- Figure 1 is a horizontal solid bowl screw centrifuge with two-bowl, in
- the horizontal solid bowl screw centrifuge according to FIGS. 1 and 2 is equipped with a self-supporting outer housing 1, which is made in one piece from cast iron.
- This outer housing has a lower mounting opening 2, which extends almost over the entire length of the outer housing 1 and is slightly larger in size than a tubular inner shell 3, which has connections 4 and 5 for the discharge of solids and liquids Is provided.
- the assembly of this tubular inner shell and the connections 4 and 5 for the discharge of solids and liquids is inserted through the lower mounting opening 2 in the direction of arrow X into the outer housing 1 until the longitudinal axes of the outer housing and the tubular inner shell match or almost match.
- There is then an assembly movement in the direction of arrow Y until the inner shell 6 rests with its front ring 6 on the front part 7 of the outer housing 1.
- the inner shell 3 is then fixed on the outer housing by means of screws 8.
- an inner ring 9 is provided, which is pushed through the mounting opening 2 into the outer housing 1 through an end opening in the interior of the inner shell 3 before the tubular inner shell is inserted, so that it moves in the direction of the arrow during the mounting movement of the inner shell X doesn't bother.
- the inner ring 9 is brought into the stop position shown in FIG. 1 on the end part 10 of the outer housing 1.
- the inner ring 9 is then fastened by screws 11 to the end part 10 of the outer housing.
- An end-face ring 12 of the inner shell is supported on the inner ring 9 and is slidably supported on the inner ring 9.
- the outer housing 1 has end openings 13, 14 through which the rotor 15 and the gear 16 can be introduced into the interior of the tubular inner shell 3.
- the pins 17, 18 are mounted in lids 19, 20, through which the end openings 13, 14 are closed.
- the tubular inner shell 3 is preferably made of a stainless steel sheet.
- connections 4, 5 for the discharge of solids and liquids are delimited by the tubular inner shell above the horizontal central plane 21 and have a rectangular cross section from the central plane 21 downwards in the direction of the assembly opening 2 and are separated by end walls 22, 23, 24, which have openings through which the rotor 15 extends.
- connections 4, 5 extend downward beyond the level of the lower mounting opening 2.
- the mounting opening 2 is closed soundproof by plates 25.
