Definitions

  • a troncated cone-shaped hopper is foreseen, which consists of a stationary top part holding the underlying mobile one by means of four pivots, to be dri ven by an electrical vibrator to facilitate the product discharge.
  • a conical part equipped with immission nozzles of air jets is foreseen to get the fluidified product and its discharge outwards with continuous effect through the said vibrating part.
  • the invention permits particular employ for hygroscopic products such as: sugar, meal, starch and other powdery products, as for instance kaolin, having a high adherence'coefficient.
  • hygroscopic products such as: sugar, meal, starch and other powdery products, as for instance kaolin, having a high adherence'coefficient.
  • female screw extractors are employed.
  • Such movement devices imply wear of the parts and the necessity of servicing and restoration work.
  • they are liable to possible blocking of the movement organ which requires dismantling of the equipment part which consequent necessity of these parts replacement.
  • the invention enables to avoid these inconveniences by using a hopper in a truncated cone shape with intermediate cylindrical band essentially consisting of-an upper part integral with the silo base and holding four suspension pivots for the underlying part fitted with. electrical vibrator apt to allow a shaking action to further the product descent.
  • the mobile part is foreseen .with the driving organs gruoped in a central position and. protected by a conical roof-like plate determining an opening, with the hopper wall, in the shape of a circular crawn for the product discharge.
  • previously conditioned air is foreseen, with a continuous employ,getting out in jets from the plate nozzles, thus giving rise to a dynamism performing the product fluidification at the silo base which furthers the discharge.
  • FIG. 1 is the view of the discharge compartment, one half of which is seen in sec tion to show the plate covering the insuffling device.
  • Fig. 2 is the .simplified scheme to illustrate the whole assembly.
  • the hopper in a truncated cone shape is foreseen with stationary upper part 2 and the underlying one 3 to be assembled by means of four suspension pivots 4.
  • This part is fitted with electrical vibrator 5, to facilitate the discharge, and it employs extracting conical part 6 in the upper central position.
  • This plate is fitted with insufflation nozzles 7 which fluidify the product and facilitate its sinking.
  • the side fan 8 is employed which takes air from out side and sends it through duct 9 supported on the mobile part through sieve 10 to get out in jets from nozzles 7 stirring and fluidifying the product contained in cone 6: in this way, its discharge is possible through opening 11 which brings into hopper 3.
  • the insufflation air is taken through conveyor 12 and put into pipe 13 which discharges through vertical duct 14 on the silo cover.
  • Air is drawn from outside through a dehumidizing device 15 which, by means of the tank inside temperature control, permits to condition the silo.
  • the dehumidation cycle foresees the air intaking through assembly 15 which employs elements absorbing lithium salts in solid state, that operate with self-regenerating effect along with air heated by means of electrical resistances controlled by a humidity-static device 16. Subsequently air passes through water cooling batteries 17 complete with thermostate 18 which insufflates the air at the controlled temperature and humidity through the nozzles.
  • An automatic filter 19 is foreseen on the silo consisting of a cylindrical part in carbon steel and containing some filtering hoses 20 in polyester tissue which depurate the air mixture sent by blower 8 before reaching the product.
  • the filtering contrivance in addition foresees a top head with automatic drive in aluminium and fitted with washing valves controlled by a cyclic 21 which alternatively determines the opening and closing.
  • a washing electrical ventilator 22 is foreseen for drawing air into the filtering heses through washing valves 21.
  • the above filter is fitted with a side sucking fan 23 which conveys the remaining air outwards. Through a deviating valve 24, the air dra wa by an automatic filter in sent through duct 25 the the ventilator 8.
  • the execution particulars, the materials, the accessory devices, the assembling means and components for binding, as well as the form of the hopper components may be performes in different ways.
