Definitions
- the invention relates to a device for the flow-through treatment of textile, nonwovens or paper with a gaseous or liquid, circulated in the device treatment agent with a standing under suction, frontal bottoms having permeable drum as a transport element, which is covered at its periphery with a mesh wherein between the bottoms of the drum sheet metal strips unbent extending straight from floor to floor, the width of which extends in the radial direction, and between the metal strips evenly distributed over the length of the drum connecting elements are arranged corresponding to the nominal distance of the immediately adjacent metal strip correspondingly wide and are firmly connected on both sides with the adjacent metal strips, wherein the respective connecting element web-shaped and provided in the circumferential direction of the drum with at least one bore, for at least one screw and / o the similar threaded fastener, and connectable to the two adjacent sheet metal strips or fasteners,
- a device of this kind is known from EP-A-0 315 961. It has the unsurpassed advantage of being highly air-permeable without reducing the stability of the drum. Without having to resort to a welded construction, are provided by the screw provided here, the circumferentially extending connecting elements with the longitudinally extending over the drum sheet metal strip around the drum. The disadvantageous structural changes in the metal during the manufacture of otherwise necessary welds are avoided in this screw construction.
- the connecting elements according to EP-A-0 315 961 have only one of the stability sufficient wall thickness. Therefore, they are bar-shaped and thicker in the area of the screws for receiving the screws than in the middle area. provides. It has been found in practice that contamination occurred in the transitions from the wall at the level of the screws to the central area and also at other locations. Fluff stuck to the fasteners and prevented the flow-through effect.
- the connecting element is formed aerodynamically favorable at least over part of its radial length. This is achieved when the radially outer region of the connecting element is formed arrow-shaped, then extends in this width to the radially inner screw and then advantageously tapers pointed back arrow. Between the screws, the width of the body is only small, the stability of influencing importance, which is why here the body can be made hollow for weight reasons.
- FIG. 1 shows a section along a conventional sieve drum device, the jacket of which consists of a strip-shaped sheet structure with screen mesh outside
- FIG. 2 shows an enlarged view of the shell of this prior sieve drum device in the same section as in FIGS. 1 and 3 in an enlarged view a same section through a new connecting element and Fig. 4, the connecting element according to Fig. 3 with a section perpendicular to that of FIG .. 3
- the Siebtrommelvortechnische of FIG. 1 corresponds to the z. B. according to EP-A-0 315 961. Reference is made to the disclosure in this document.
- a screen drum device basically consists of an approximately rectangular housing 1, which is subdivided by an intermediate wall 2 into a treatment space 3 and a fan space 4.
- the fan room can also be arranged in a separate from the screen drum housing 1, not shown here, separate fan housing. In any case, the fan sets the interior of the drum 5 under induced draft.
- the subject matter of the patent is also the drum construction on a wet treatment device, which can also serve only for sucking off liquid. The overall construction is then adjusted accordingly.
- heating units 7 are arranged above and below the ventilator 6 and consist of tubes through which heating medium flows.
- the screen drum is covered in the area not covered by the fabric 9 inside by an inner cover 8 against the induced draft.
- the effective skin of the screen drum is formed by the sheet metal strip structure of FIG. 2 described below. This is wrapped on the outside by a fine-meshed sieve 19, which is held taut on the end face of the drum at the two bottoms 1 1, 12.
- the previously known sheet metal strip structure consists of axially aligned sheet metal strips 10, the radially aligned height of FIG. 2 shows.
- the sieve-shaped covering 19 rests only on the radially outer edges of the sheet-metal strips 10.
- the metal strips 10 are attached at a defined distance next to each other on the two floors 11, 12 by screws, not shown. So that this distance is fixed over the width of the drum, serving as spacers, designated as a whole with 20 connecting elements are provided, which are connected by means of screws 29, 29 'and 30, 30' with the sheet metal strip 10.
- the connecting elements 20 have according to FIG. 2 at their contact surfaces on the sheet metal strip 10 a rectangular flange 22.
- the radially outwardly extending region of the connecting element 20 consists of the web 24.
- Radially on the inside, the connecting element 20 has a widened foot 28, while the remaining region 26 of the connecting element, except for the screw passages 25, 27, is narrow in cross section ,
- the connection of the connecting elements 20 with each other by means of rods 29, 29 'and 30 30' with threads at least at the two ends to which then the nuts 31 are screwed within a connecting element 20 '.
- the novel connecting element 20 “according to Figures 3 and 4 has an overall streamlined design over its radial extension, and at its two ends provided with the bores 32, 33 has a radially directed arrowhead 34, 35 which offers less resistance to the fluid flowing past. Between the area in the amount of holes 32, 33, the connecting element 20 remains “unchanged wide according to the width as it is necessary for the holes 34, 35. As a result of this shaping of the connecting element 20 "no edge or groove is present, which can give rise to pollution.
- the connecting element 20 in the middle region, is provided with a cavity 36, whose walls 37, 38, which only provide stability, extend in the same thickness and in parallel.
- the cross-sectional width of the walls 37, 38 in the amount of the cavity 36 corresponds approximately to the width of the walls in the amount of holes 32, 33, as can be seen from Fig. 4.
- the connecting element according to FIGS. 3, 4 is cast from metal and from one piece. Only the holes 32,33 are rework. At least at one point around the drum are the individual screws 29, 30, the foot of which is provided with a hollow thread and the head with a normal fitting into the hollow thread mandrel, to connect by a so-called lock to a circle. At least at this point, the necessary nut screw has a larger diameter.
- a connecting element according to FIG. 3 is no longer usable. At least at this point, to fulfill the task, the connecting element consist only of an arrow-shaped bent sheet metal, which has the wall thickness according to the walls 37, 38, but otherwise is hollow for receiving the lock.
