- an advantageous variant may be characterized in that the clamping lever has a fork-shaped end with holes in which a transverse bolt is inserted, and a standing with the clamping bolt threaded draw bolt is screwed into a radial threaded bore of the transverse bolt.
- the clamping bolt is connected to the threaded pull pin via a clamping piece, the clamping bolt is mounted with its holding head in a slot of the clamping piece and the threaded pull pin is screwed into a radial threaded bore of a clamping pin, in two opposite Holes of the clamping piece is added.
- the shape of the suction device AER corresponds to a hollow ring body, it may also be referred to as toroidal, wherein a central pour opening SOE is bounded by a wall WAN and in this wall a plurality of suction holes ASB is formed, in the present example 50 holes. More precisely, the bores are formed in an upper, upwardly and outwardly conically widened wall section KWA, which merges downward into a substantially cylindrical wall section ZWA.
- the holes ASB are in a manner to be described in more detail below about the interior of the hollow body with a pipe connection, namely a pipe socket in connection ROS in the operating state of the device via a suction line, not shown, such as hose, is connected to a suction device. Thanks to the obliquely upward bores ASB ambient air is sucked in and formed a kind of vacuum cone over the pouring spout.
- the suction holes ASB have a rounding ARU at least at their outer end pointing toward the pouring opening SOE, in the present case, however, at both end regions, by means of which a local vortex formation and thus the noise development are reduced.
- the suction device can be easily cleaned. Therefore, it can be provided that it consists of two or more parts and can be dismantled, which will be described in more detail below.
- the suction device AER consists of at least one upper part OTE and a lower part UTE, wherein the upper part and lower part are held together in the state of use by a clamping device SSM and after opening of the clamping means to expose the annular body interior are separable.
- a separating plate TRP located between the upper part OTE and lower part UTE is provided with at least one passage opening DUT.
- the upper part OTE is shown in more detail in Figs. 3 to 5, the lower part UTE in Figs. 7 and 9 and the partition plate TRP in Figs. 6 and 8.
- TRP partition plate
- UTE has In practice, polypropylene proven, but it should be clear that the professional depending on the application, other useful materials are available.
- the annular body of the suction device AER has at least one lower chamber UKA and at least one upper chamber OKA, the at least one lower chamber UKA and the at least one upper chamber OKA communicating with each other via at least one passage opening DUT, in the present example two stand.
- a multi-part upper, inner, annular chamber OKA and a lower, about 180 ° extending outer chamber UKA is provided, wherein the pipe socket ROS in this lower, outer chamber UKA and the suction holes ASB in the upper, inner chamber OKA lead.
- the air together with any existing dust or a gas or aerosol is thus sucked through the suction holes ASB first into the inner, upper chamber OKA and passes from here to outer sections of the chamber, tangentially outwardly leading vanes LEF (see Fig. 5) the flow to lead. From these said chamber sections, the air through the openings DUT of the partition plate (see Fig. 8) is sucked down into the lower, outer chamber UKA (see Fig.
