摘要:
A method of treating and processing alkaloid, oil and protein-containing lupine seeds for the extraction of products from the lupine seeds by means of targeted fractionation is described, whereby the comminuted lupine seed is de-oiled by introducing a solvent and the residue is depleted of substances soluble in the acid range, preferably of alkaloids, by adding acids. The invention is characterized by the provisions that the lupine seeds are comminuted and/or shaped to form discoid flakes in such a way that after pre-crushing of the shelled or non-shelled seed containing the plant seeds the comminution of the plant seeds is carried out by means of a cooled flocculating roller, and the seed is heated by indirect supply of heat, largely with exclusion of water, and that after de-oiling the depletion of the flakes of substances soluble in the acid range, preferably of alkaloids, is performed by aqueous extraction, with a refined product of reduced alkaloid level and an aqueous extract being obtained.

A rotary piston pump for the delivery of liquids and for the delivery of liquids containing solids. The rotary piston pump includes a pump housing which is provided with an inlet and an outlet. The pump housing includes a lining. Disposed in the pump housing, or inside the lining, are at least two counter-rotating rotary pistons, which form pump spaces during their rotation. During the rotational movement, the rotary pistons are sealed against one another, against the pump housing and against the lining. Disposed in the pump housing and/or in the lining, in the spatial vicinity of the inlet and/or the outlet, are means with which the pulsation can be reduced or even completely prevented.

The invention discloses a joint for the transmission of torques and axial forces in conjunction with an eccentric rotary motion. In a preferred embodiment, the joint according to the invention is used in an eccentric screw pump for connecting the drive to the pump rotor. The joint connects a coupling rod and a tool and/or a drive to one another. When the joint is used in an eccentric screw pump, the tool is the rotor of the pump. Furthermore, the joint is provided with at least one casing. The axial forces acting on the joint can be transmitted by a first joint part and the torques by a second joint part.

The rotary piston pump includes two counter-rotating rotary pistons and an oval pump housing. Every rotary piston has a rotary piston vane and is provided with a contact element. The contact points of the flanks of the two rotary pistons in which the two rotary pistons form a friction pairing are provided with a contact element each. The interior of the oval pump housing is likewise provided with an exchangeable contact element.
摘要:
A stator for an eccentric spiral pump comprises a hollow body of an elastic material which has a casing comprising a plurality of segments extending in a longitudinal direction of the casing. Adjacent segments are interconnected along longitudinal sides at variable angles to each other, so that the segments enclose an entire circumference of the casing. Surfaces of the segments are of a planar configuration, so that a closed casing of polygonal cross-section is formed by the interconnected segments. The hollow body of elastic material is of a matching polygonal cross-section to achieve positive contact with the casing.

摘要:
A method and a device for fixing and synchronising rotary pistons in a rotary piston pump are disclosed. The rotary pistons are introduced into the pump space of the rotary piston pump. A shaft stub of each rotary piston is then pushed through a pump rear wall onto a driveshaft provided for the respective rotary piston. The rotary pistons are aligned and synchronised in the pump space by means of a template, the template being fixed detachably to a pump housing. The shaft stubs of the respective rotary piston are connected, after the synchronisation, in each case by means of a clamping device in a friction-locked manner to the respective driveshaft, outside the pump space.
