Abstract
Description
- 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. In the cen tral upper position of the mobile part, 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. For these products, female screw extractors are employed. Such movement devices imply wear of the parts and the necessity of servicing and restoration work. In addition, 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. In order to overcome the cohesion effect, 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.
- A not limiting version is illustrated by the drawings of Table 1, where 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.
- In a version , at the silo discharge, 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.
- For the air circulation, 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 throughvertical duct 14 on the silo cover. Air is drawn from outside through a dehumidizingdevice 15 which, by means of the tank inside temperature control, permits to condition the silo. The dehumidation cycle foresees the air intaking throughassembly 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 throughwater cooling batteries 17 complete withthermostate 18 which insufflates the air at the controlled temperature and humidity through the nozzles. - The necessity of checking the insufflation air depends on the outer room. conditions and allows more or less warm air according to the resurting thermal exchange. This permits to suit the product to the room exigencies with a view to avoiding invonveniences of different kinds, such as incrusta tions due to exceeding humidity of fermentations in consequence of lowered hygroscopic grade.
- An
automatic filter 19 is foreseen on the silo consisting of a cylindrical part in carbon steel and containing somefiltering 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 throughwashing valves 21. The above filter is fitted with aside sucking fan 23 which conveys the remaining air outwards. Through a deviatingvalve 24, the air dra wa by an automatic filter in sent throughduct 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.
