Definitions
- the invention is based on a device for the preparation of liquid to thin-slurry media according to the preamble of the main claim.
- a large number of methods and devices for processing liquid to thin-pulp media have become known, which are used primarily in the fields of wastewater treatment, water treatment and the production of colloidal mixtures.
- By crushing grains of macroscopic size or by connecting several molecules into clusters, a colloidal structure is created in the processed medium.
- a known device of this type (DE-OS 32 41 011) the medium to be treated is funnel-shaped from above Filled container, which it flows through due to gravity from top to bottom and leaves through a drain opening provided at the lower end of the funnel.
- This device creates a vortex-like vortex which is intended to intensively mix the constituents present in the medium, for example cement and water.
- This device has also become known in a further development (DE-OS 33 25 952), in which a two-chamber system is used.
- the inner, funnel-shaped chamber in turn serves to swirl the medium flowing through it from top to bottom due to gravity, while the outer chamber serves to return the medium leaving the inner chamber to open the inlet of the inner chamber.
- a rotor mounted in the vertical axis of the container is used for the return, the vanes of which are located in the outer chamber below the outlet opening of the inner chamber and which conveys the medium back against gravity to the inlet opening of the inner chamber.
- the device according to the invention with the characterizing features of the main claim has the advantage that a high energy input is possible, that a strong suction is exerted on the medium and that gravity for the transport of the medium from the outlet opening of the inner chamber through the outer chamber to Entry opening of the inner chamber can be used.
- the device according to the invention can also be used for wastewater treatment, wherein organic constituents of the wastewater are split up, in some cases thereby additionally brought into solution or else precipitated.
- organic constituents of the wastewater are split up, in some cases thereby additionally brought into solution or else precipitated.
- There may also be a change in the structure of the water for example due to cluster formation, which leads to a change in changes in the properties of water, for example with regard to its solution properties or the absorption capacity by plants.
- FIG. 1 shows a device according to the invention with a bottle-shaped inner chamber and, seen from the outside, a convex outer chamber,
- FIG. 2 shows a device according to the invention with a bottle-shaped inner chamber and a two-part, heart-shaped outer chamber
- FIG. 3 shows a section through a centrifugal wheel according to the invention with tortuous radial channels and
- Fig. 4 shows another embodiment of a centrifugal wheel according to the invention, also in section.
- the device shown in FIG. 1 has a container with a bottle-shaped, upwardly tapering inner chamber 1 and a bell-shaped outer chamber 2 arranged around it, both of which are arranged rotationally symmetrically about an axis of symmetry 3.
- a suction nozzle 4 is immersed, which is connected to a centrifugal wheel 5 in a form-fitting manner with its end protruding from the bottle neck of the inner chamber 1.
- the centrifugal wheel 5 is also arranged rotationally symmetrically with respect to the axis of symmetry 3 of the two chambers 1 and 2 and is provided with radial channels 6, which run from the area around the axis of rotation to the outer boundary of the centrifugal wheel 5 and where they end in outlet openings 7 * .
- a drive shaft 8 is articulated to the centrifugal wheel and is connected to a drive unit (not shown).
- the drive shaft 8 is guided into the outer space through a recess 9 in the outer wall 10 of the outer chamber 2, a seal being able to be provided between the shaft 8 and the outer wall 10.
- the outer wall 10 is also provided with a pressure relief valve 11 and a vacuum valve 12 for regulating the pressure in the outer chamber 2.
- the outer wall 10 has two further recesses, namely an inlet opening 13 and an outlet opening 14.
- the bottle-shaped outer wall 15 of the inner chamber 1 is firmly connected to the outer wall 10 of the outer chamber 2, but between the inner chamber 1 and the outer chamber 2, a plurality of passage openings 16 are provided, in front of which flow plates 17 are arranged.
- the device according to the invention shown in FIG. 2 has a two-part outer chamber 102, with an upper chamber 118 and a lower chamber 119, which are connected to one another via a circular opening 120.
- the outer wall 110 of the upper chamber 118 is in turn provided with a pressure relief valve 111 and a vacuum valve 112 in its upper region, while in the region of the lower chamber
- the inner chamber 101 is connected to the lower chamber 119 via passage openings 116.
- a suction port 104 which is connected with its end projecting from the bottle neck in a form-fitting manner to a centrifugal wheel 1Q5, which is arranged rotationally symmetrically about an axis of symmetry 103, which is also the axis of symmetry of the inner chamber 101 and the two-piece outer chamber 102.
- the centrifugal wheel 105 has radial channels 106, which run radially from the area around the axis of symmetry 103 to the outside of the centrifugal wheel 105 and open there in outlet openings 107.
- the radial channels 106 open into the intake manifold 104, for which purpose they are angled in the direction of the axis of symmetry 103.
- a drive shaft 108 is articulated, which is guided through a recess 109 in the outer wall 110 of the two-part outer chamber 102, a sealing element 120 being provided between the drive shaft 108 and the outer wall 110 is seen.
- the centrifugal wheel 105 is provided with vanes 121 through which the medium in the lower chamber 119 can be set in rotation.
- the outer wall 110 of the outer chamber 102 is constricted and a guide ring 122 is formed, which on the medium thrown out of the radial channels 106
- channels 123 are provided in the centrifugal wheel 105, which run obliquely from top to bottom and through which medium can flow from the upper chamber 118 into the lower chamber 119.
- FIG 3 shows a section through a centrifugal wheel 5 according to the invention, in which the radial channels 6 run in an arc from the inside to the outside, the outlet openings 7 being arranged approximately tangentially to the outer boundary of the centrifugal wheel 5.
- FIG. 4 shows a further variant of the course of the radial channels 6 within the centrifugal wheel 5, in which the radial channels 6 are wound in a loop shape.
- the start and end of the loop are of course in different horizontal planes of the centrifugal wheel 5, the radial channels 6 are therefore not shown in section here.
- the device In interval operation, the device is filled with the medium to be treated via the inlet opening 13 to just below the centrifugal wheel 5. Thereupon the inlet opening 13 is closed and the centrifugal wheel 5 is set in rapid rotation by a drive unit (not shown) via the drive shaft 8. The resulting in the radial channels 6 The medium is suppressed by suction from the inner chamber 1 via the suction nozzle 4 and, owing to the centrifugal force, is thrown out of the outlet openings 7 of the radial channels 6 into the outer chamber 2. The medium returns from the outer chamber 2 through the passage openings 16 into the inner chamber 1. This process is maintained until the medium has reached the desired consistency. The same procedure is followed with the device according to FIG.
- the medium thrown out of the outlet openings 107 of the radial channels 106 being distributed through the guide ring 122 to the two chambers 118 and 119.
- the medium returns from the outer chamber 102 through through openings 116 into the inner chamber 101 and is sucked in from there via the intake port 104.
- the medium can be removed from the device through the outlet opening 14 or 114. It is also possible to make a continuous passage of the medium through the device.
- the inlet opening 13 is arranged in such a way that the medium to be treated is passed directly into the inner chamber 1 and can only get into the outer chamber 2 after passing the centrifugal wheel, from where it is continuous via the outlet opening 14 from the device is removed.
