Definitions

  • the invention relates to a suction unit, in particular for the suction of textile machines, according to the preamble of claim 1.
  • the known suction units have the disadvantage that the filter screen clogs rather quickly when there is a high proportion of fiber flying in the air to be cleaned, so that it is comparatively often necessary to switch to cleaning operation. In many cases, the filter screen cannot be completely cleaned.
  • the cone-shaped partition is a nuisance to the cleaning operation, because together with the rather small central opening, it forms a kind of nozzle that whirls up the deposited fiber fly, which is unfavorable for various reasons.
  • the large valve flap according to the invention which acts as a non-return valve in suction mode, it can be achieved that the excess pressure initially builds up in the cleaning mode and then the air in the lower suction chamber is relaxed by opening the large non-return valve. This leads to a correspondingly intensive brief flow through the filter screen in the reverse direction, as a result of which the accumulated filter cake is removed.
  • the recess in the partition does not act as a nozzle, since there is a very large flow cross section.
  • the truncated cone-shaped partition has the advantage that it forms a kind of funnel for the filter cake that comes off, so that it can slide in one piece into the lower part of the suction space.
  • the non-return valve locked it is necessary to have the non-return valve locked until a corresponding pressure has built up, and then to have it opened with a delay.
  • Such an opening behavior can either be achieved with a locking device that counteracts the opening, or with a forced control, a locking device being preferred. It is understood that the locking device does not close the check valve may be difficult.
  • a fairly small opening in the partition for suction operation can be combined with a very large opening in the partition for cleaning operation.
  • a comparatively large proportion of the fiber flue which arises and is sucked in can be deposited in the bottom region of the suction space without it ever getting into the region of the filter screen.
  • the large non-return valve favors the detachment of the filter cake in cleaning operations.
  • the suction connection is conically widened when entering the suction chamber, so that the desired relaxation and reduction of the flow speed take place slowly and any nozzle effect in the area of the deposited fiber flight is prevented.
  • suction connection can be covered with an additional non-return flap, which prevents the escape of fiber fly in the cleaning operation via the suction hoses of the suction unit.
  • a locking flap covering the opening also offers the advantage that the relaxation can proceed abruptly in the cleaning area, with a certain deflection of the flow in suction operation from the central axis and thus a swirling in front of the filter sieve being simultaneously effected in suction operation.
  • the check valve according to the invention can be pivoted on one side, although a multi-part design is possible in itself. Due to the one-sided pivoting, a filter device of an outlet opening can practically be covered at the same time, so that the filter cake does not get into this area.
  • the suction connection can be arranged such that the air flow is guided past the filter device in suction operation, so that fibers located there are taken along by the suction flow and either settle on the floor of the relaxation space or at most are taken to the filter screen.
  • the filter device can also be provided in the suction mode at a point of comparatively large flow, so that there is negative pressure which additionally supports the sucking back of the fibers.
  • the single figure is a schematic sectional view of an embodiment of a suction unit according to the invention.
  • a suction unit 10 has a suction connection 12 which opens into a suction chamber 14.
  • the suction chamber 14 is formed by a suction chamber pot 16 and has a comparatively large volume, the suction chamber 16 essentially having the shape of an elongated cylinder.
  • a frustoconical partition 18 is provided at the top of the suction chamber pot 16, a filter sieve 20 being stretched above the partition 18.
  • the filter screen 20 consists of a plastic fabric, which is designed so that, for example, cotton fibers have a slight tendency to adhere there.
  • a fan 22 is arranged above the filter screen 20, the suction connection 24 of which is connected to the suction chamber pot 16 above the filter screen 20.
  • a cleaning channel 26 opens into the suction chamber pot 16 above the filter screen 20, which is connected to a pressure port 28 of the fan 22.
  • the switchover between cleaning operation and suction operation takes place via a changeover flap 30, which connects the pressure port 28 to the cleaning duct 26 and separates a compressed air outlet 32 from the pressure port 28 and at the same time opens a suction air flap (not shown in the figure) for the blower.
  • the check valve 34 In the central region of the frusto-conical partition 18, the check valve 34 according to the invention is provided in such a way that it completely covers a recess 36 in the partition 18. It is preferred to make the recess 36 so large that its diameter is at least half the diameter of the suction space pot 16 corresponds, with the frustoconical partition 18 adjoining the recess 36.
  • the check valve 34 is mounted on one side with a pivot bearing 37 on the partition 18, a spring, not shown, holding the check valve 34 in the closed position.
  • the spring is provided as a spiral spring immediately adjacent to the pivot bearing 37 and compensates for the weight of the check valve 34.
  • a latching device is provided with a latching lug pointing upwards and preventing the movement of the check valve 34 downward, which prevents movement of the check valve 34 from the position adjacent to the recess 36 with a still small force .
  • the locking lug is also mounted on a smooth-running leaf spring, so that the reclosing of the check valve 34 is not hindered due to the spiral spring provided on the pivot bearing 37.
  • an opening 38 is provided in the partition 18, namely in the non-return flap 34, which can be covered with a locking flap 40.
  • the locking flap 40 lies loosely on the opening 38 if it is not raised above the air flowing through the opening 38 during suction operation. In cleaning operation, it also acts as a check valve, which ver relaxes the air in the space above the partition 18 into a relaxation space 42 below the partition 18 prevents until the check valve 34 triggers.
  • the suction connection 12 is also covered with a further non-return valve 44 which prevents air from escaping through the suction connection 12 in the cleaning operation.
  • the suction chamber pot 16 has an outlet opening 46 which is covered by a filter device 48 which, in cleaning operation, is also essentially covered by the non-return flap 34.
  • the air originating from the suction connection 12 spirals along the wall of the suction chamber pot 16 and thus wipes off any fiber fly that could have been deposited on the filter device 48 during the cleaning operation.
