Definitions

  • the invention relates to a cleaning device for a filter of a dust filter device, the cleaning device comprising means for feeding air through the filter to a direction opposite to the normal air flow direction, and a frame element that is arranged outside the filter to move in relation to the filter and is provided with opening elements and nozzles, the opening elements being arranged to open the gaps between the lamellas of the filter in response to a movement of the frame element, and the nozzles being arranged to direct an air jet parallel to the normal air flow between the lamellas opened by the opening elements and to remove dust from between the lamellas.
  • Dust filter devices include, for example, different aspirators, particularly industrial aspirators, ventilation systems, etc.
  • Previously known in the field are, for example, systems in which an air flow that cleans the filter is generated by the motor of an aspirator. Examples for such systems include, for example, the solutions presented in German Patents 595,686 and 666,446.
  • a drawback of the above solutions is that they are inefficient and complicated.
  • the filter element also has to be detached and then attached to the blow side of the aspirator.
  • a problem here is that the action is laborious to carry out and that impurities spread to the environment.
  • Another previously known basic solution is to detach the filter to be cleaned from the aspirator and to clean it, for example, by compressed air.
  • a drawback of the solution is that it is laborious to perform and that impurities spread to the environment. The cleaning result is also fully dependent on how careful the person doing the cleaning is.
  • the dust When the dust is light and porous, it remains between the lamellas in the suction step, forming a continuous felt-like mat. During the cleaning, a pressure impact penetrates between the lamellas, cleaning their upper ends. The dust then wedges between the lamellas and air flows out through the porous dust; the fibrous material, however, does not become detached.
  • the object of the invention is to provide a cleaning device by which the drawbacks of the prior art can be eliminated. This is achieved with a cleaning device according to the invention, the device being characterized in that the air for the means and nozzles of the frame element is arranged to be fed through a feed pipe arranged at the symmetry axis of the filter.
  • the major advantage of the invention is its efficiency: the filter can be cleaned efficiently and quickly under all conditions.
  • the structure described in the invention is sturdy, small and reliable, and it allows a rotational movement of the frame element without any complicated mechanisms.
  • a further advantage of the invention is its simplicity, on account of which the introduction and use of the invention are cost-effective.
  • Another feature contributing to the cost-effectiveness of the introduction to use is that the invention can also be applied in connection with aspirators currently used.
  • the filters can be cleaned mechanically without rotating them, so the filters can be sealed better than before and the risk of dust leak diminishes. Due to the power transmission solution a rotation motor can be placed outside the filter unit in a clean space.
  • compressed air can be distributed both to the frame element and to compressed-air guns in a particularly advantageous manner, so that the inconvenient reciprocating movement can be eliminated.
  • the distribution of air further enables the simultaneous use of a compressed-air gun and mechanical agitation, which reduces the time spent for cleaning the filters.
  • Figure 2 shows a general view illustrating a basic principle of cleaning a filter developed in connection with the solution illustrated in Figure
  • Figure 3 shows a detail of Figure 2 in the direction of arrow A
  • Figure 4 shows a general side view of a cleaning device according to the invention.
  • Figure 5 shows an enlarged view of a structural detail of Figure 4
  • Figure 6 shows a detail of a cleaning device illustrated in Figures 4 and 5
  • Figure 7 shows a cleaning device according to the invention in connection with an industrial aspirator.

  • the figure shows a filter 1 and means
  • the means 2 comprise, for example, a nozzle element 3 and a compressed-air container 4.
  • the nozzle element 3 is arranged to direct an impact of compressed air to the inner surface of the filter 1 in the desired manner, as shown by arrows N in Figure 1.
  • the normal air flow direction is indicated by arrows M in Figure 1.
  • the nozzle element 3 is rotated by the impact of the air flow.
  • Figure 1 can be found, for example, in an industrial aspirator, a welding gas aspirator, or in some other such apparatus or system.
  • Figures 2 and 3 show a general view illustrating a basic principle of cleaning a filter developed in connection with the device illustrated in Figure 1.
  • like reference numbers indicate correspondingly as in Figure 1.
  • Figure 3 shows an enlarged view of a detail of Figure 2 in the direction of arrow A.
  • the cleaning device comprises a frame element 5 arranged outside the filter 1 to move in relation to the filter.
  • the frame element 5 is provided with opening elements 6 and nozzles 7.
  • the opening elements 6 are arranged to be in contact with the outer surface of the filter 1 and to open the gaps between lamellas 1a of the filter 1 in response to a movement of the frame element 5.
  • the nozzles 7 are also arranged to direct an air jet parallel to the normal air flow M between the lamellas 1a opened by the opening elements 6 and to remove the dust from between the lamellas 1a.
  • a drawback of the basic principle illustrated in Figures 2 and 3 is that the frame element 5 can only rotate 180° to and fro, as the means for feeding air prevent a continuous rotating movement in one direction only.
  • FIGS 4 to 7 show a cleaning device according to the invention applying the basic principle known from Finnish Patent Application 961 ,873.
  • the basic idea of the invention is to provide a structure that makes the implementation of the basic principle known from Finnish Patent
  • An essential idea of the invention is that air for the means 2 and the nozzles of the frame element 5 is arranged to be fed through a feed pipe 8 arranged at the symmetry axis of the filter 1.
  • air is arranged to be fed into the feed pipe 8 through a support 9 serving as a support member of the feed pipe.
  • the feed pipe 8 comprises an element of telescopic pipes 8a, 8b that is arranged to serve also as a lifting device for the filters 1.
  • the lower part of the frame element 5 is mounted on the feed pipe 8 by means of a bearing element 10, and the upper part on a tooth-wheel rim 12 by means of a sliding fit allowing a vertical movement, the tooth-wheel rim being arranged to transmit the rotational movement to the frame element 5.
  • the bearing element 10 is also arranged to distribute air to the means 2 and. the nozzles 7 of the frame element 5.
  • the rotational movement of the frame element is made possible by a power source 13, for example an electric motor.
  • the opening elements 6 serving as cleaning trails are attached to the vertical pipes 5a, 5b. So when the tooth-wheel rim 12 rotates, the frame element 5 rotates, and the opening elements 6 circle the filters 1 and clean them in the above described manner.
  • cleaning elements 16 for example cleaning cams, by means of which material fallen off the filters 1 onto the conical part of the jacket 14 is scraped and dropped into a collecting receptacle 17.
  • the feed pipe 8 comprises telescopic parts 8a, 8b that are adjustable in relation to each other by means of an adjusting element 18.
  • the adjusting element 18 can be, for example a screw element. By means of the adjusting element the filters can be lifted and thus compressed against the jacket.
  • Air is fed into the feed pipe 8, for example through a solenoid valve 19 and a support 9. So the air flows into the feed pipe and further to the bearing element 10 that distributes the air flow to the means 2, for example to a compressed-air gun, and the vertical pipes 5a, 5b of the frame element.
  • the air is directed to the means 2 with an angular part 20 and pipe elements 21 , 22.
  • the pipe elements 21 and 22 are detachable and attachable with one another by means of connecting sleeves 23, 24, so that a pipe element and a sleeve form a unit of the height of the filter.
  • a pipe solution like this the filters 1 with the compressed-air guns can be installed and removed one at a time.
  • nozzles 7 can be, for example apertures of the size of about 1mm provided in the vertical pipes 5a, 5b.
  • the filter may comprise one or more filter elements, for instance two filter elements as illustrated in Figure 7, etc.
