Definitions

  • the invention relates to a blowing nozzle for blowing off liquids from surfaces, for example a sheet metal surface, with a tubular body, on the jacket of which are attached approximately tangentially connected plate-like lips that run towards one another to form a blow-out slot that runs parallel to the body, and with one in the body arranged plate-shaped cleaning element which is displaceable relative to the blow-out slot.
  • the plate-shaped cleaning element is arranged on a slide which is displaceably mounted on the inside of one lip and is actuated by pneumatic cylinders arranged inside the blow nozzle.
  • pneumatic cylinders arranged inside the blow nozzle.
  • This enables remote control, so that the cleaning element can be pushed through the blow-out slot from time to time without having to interrupt the operation of the blowing nozzle.
  • pneumatic cylinders in the blow nozzle is relatively complex. The blow nozzle must be opened for maintenance work on the hydraulic cylinders used as the drive.
  • the invention is based on the object of improving the known blowing nozzle with a displaceable plate-shaped cleaning element in such a way that the drive for the cleaning element takes place from the outside and there are only simple mechanical parts which do not disturb the blowing operation in the blowing nozzle.
  • the transmission has at least two adjusting rods running perpendicular to the cleaning element, each of which is provided with an eccentric lever connected to the cleaning element and is rotatably mounted about its longitudinal axis.
  • Each eccentric lever can engage with a roller in a receptacle arranged on the cleaning element, so that there is an articulated connection that allows adjustability between the cleaning element and the eccentric lever.
  • the adjusting rods protruding from the body of the blow nozzle are connected to a common drive via the ends protruding from the blow nozzle, so that they can also be rotated together and move the cleaning element perpendicular to the blow-out slot without the risk of jamming.
  • the outer ends of the adjusting rods are connected via a chain drive to a pneumatic cylinder which serves as a drive and which is fastened, for example, to the outside of the blow nozzle body.
  • the cleaning element is a tongue-like sheet which constantly engages in the blow-out slot and which can be displaced along the blow-out slot.
  • the cleaning element thus has a relatively small width and does not extend over the length of the blow-out slot, but can be moved back and forth along the blow-out slot, but cannot be adjusted perpendicularly to the blow-out slot, as in the aforementioned first embodiment of the invention.
  • the tongue-like sheet is attached, for example, to a rope running parallel to the blow-out slot and guided over deflection rollers, which takes the tongue-like sheet with it when it is being adjusted and pulls it through the blow-out slot.
  • the rope can be actuated, for example, by a handwheel attached to the outside of the blow nozzle body.
  • the blowing nozzle 1 shown in FIGS. 1 to 3 has a cylindrical body 2 in the basic form, to which tangential plate-like lips 3 and 4 adjoin in one piece, which end at a short distance from one another, so that they extend over the length of the blowing nozzle 1 Form and limit blowout slot 5.
  • the lower lip 4 extends approximately horizontally in the exemplary embodiment shown, its inside delimiting the underside of the blow-out slot 5.
  • the inclined other lip 3 delimits the blow-out slot 5 with its outer end.
  • a sheet 6 On the inside of the lip 4 is a sheet 6 extending over the entire length of the blow-out slot 5, which is in the form of a plate Cleaning element is formed and can be pushed back and forth according to the arrow 7 shown in Fig. 1.
  • the sheet 6 In Fig. 1, the sheet 6 is shown in its most retracted position, while Fig. 6 shows the sheet 6 in the extended position in which it has been pushed out through the blowout slot 5 to the front. In this way, contaminants that settle in the blow-out slot 5 can be pushed out.
  • the thickness of the sheet 6 corresponds approximately to the height of the blow-out slot 5, so that by pulling the sheet 6 out of the blow-out slot 5 once, it can be freed of all impurities contained in it.
  • two adjusting rods 7 are provided in the exemplary embodiment according to FIGS. 1 to 3, which are arranged parallel and next to one another at a distance and are rotatably mounted about their longitudinal axis in bush-shaped bearings 8 and 9.
  • Bearings 8 and 9 can be maintenance-free bearing bushes.
  • the bearing 8 is arranged in the wall of the body 2, while the bearing 9 is located in an eye 10 which is attached to the inner wall of the body 2 and lies at a distance above the lip 4.
  • each control rod 7 a horizontally extending lever 11 is attached at one end below the eye 10.
  • a roller 12 is rotatably mounted on the underside thereof and engages in a receptacle 13 located on the top of the sheet 6.
  • This lever 11 acts as an eccentric to move the sheet 6 between the end positions shown in FIGS. 1 and 2 when the corresponding adjusting rod 7 is rotated.
  • each control rod 7 two sprockets 14 and 15 are arranged one above the other outside of the bearing 8 and thus on the outside of the body 2, and are connected in a rotationally fixed manner to the control rod concerned.
  • a chain 16 and 17 runs over each sprocket 14 and 15, the chain 16 connecting the corresponding sprockets 14 of the two adjusting rods 7 and the chain 17 connecting the sprockets 15 of the two adjusting rods 7.
  • the chains 16 and 17, together with the horizontally arranged chain wheels 14 and 15, form the rotary drive for the two adjusting rods 7, the two adjusting rods always being rotated simultaneously by the mutual coupling.
  • each chain 16 and 17 is interrupted, the respective ends being attached to a chain tensioner 18 and 19, respectively.
  • a pneumatic cylinder 20 which is attached to the outside of the body 2 of the blow nozzle 1.
  • the chain tensioners 18 and 19 are attached to the ends of the piston rod 21 of the pneumatic cylinder which protrude from the two ends of the pneumatic cylinder 20.
  • the two chains 16 and 17 are connected to the actuating piston which is displaceable in the pneumatic cylinder 20 and is not shown here.
  • the chains are shifted in one direction or the other, so that the two adjusting rods 7 are rotated accordingly via the chain wheels 14 and 15 in order to move the plate 6 from the retracted position into push out or pull out the exhaust slot 5.
  • the sheet 6 is in the retracted position shown in FIG. 1, no side of the actuating piston of the pneumatic cylinder 20 needs to be pressurized. Rather, pressure medium is only necessary if the actuating piston is to be displaced in order to adjust the plate 6.
  • the blowing nozzle 31 in turn has a body 32 which is cylindrical in its basic form and to which plate-like lips 33 and 34 adjoin tangentially and which form and limit a blowout slot 35 which extends over the length of the body 32.
  • a tongue-like sheet 36 On the inside of the approximately horizontally extending lower lip 34 there is a tongue-like sheet 36 which, with its outer tip 37, constantly protrudes from the blow-out slot 35, as shown in particular in FIG. 5, but can also be seen in FIG. 4.
  • FIG. 5 also shows that the tongue-like sheet 36 is relatively narrow and accordingly only extends over a small part of the length of the blow-out slot 35.
  • a wire cable 38 is provided inside the body 32 and is guided in tensioned fashion over deflection wheels 39, 40 and 41 and drive wheel 42.
  • 4 shows that the deflection wheels 39 and 40 are mounted on a block 43 which is fastened to the end wall 44 of the body 32.
  • the deflection wheel 41 is mounted in a manner not shown in the body 32, for example directly on the inside of the lip 34.
  • the drive wheel 42 is fastened on a shaft 45 which extends through a bearing housing 46 and is supported therein.
  • a handwheel 47 is fastened, with the aid of which the wire cable 38 can be moved when the tongue-like sheet 36 serving as a cleaning element is to be moved along the blowout slot 35.
  • the wire rope 38 need not extend the entire length of the body 32. Rather, it would also be conceivable to arrange at both ends of the body 32 an arrangement as shown in FIG. 5, so that then two tongue-like plates 36 serving as cleaning elements can each be displaced approximately over half of the blow-out slot 35.
