Definitions

  • This invention relates to separating apparatus for separating heavier particles/granules or the like from lighter particles/granules/waste matter or the like.
  • the invention has particular application to the re­cycling of foodstuffs for animals and birds as such foodstuffs may become intermixed with waste matter and separation of waste matter is desirable. It is envisaged that the invention will typically be utilised by bird breeders who feed their stock primarily on seed or grain. Such seed or grain is generally scattered on the ground or placed in containers and during the course of feeding some of the seed or grain is displaced by the birds and intermixed with waste matter such as chaff from the seeds or grain, feathers, dust and grit and consequently is not consumed by the birds.
  • the object of this invention is to provide apparatus for the separation for example of whole seed and grain from lighter weight waste matter so that the whole seed and grain may be re-used.
  • separation apparatus for separating heavier material from lighter material wherein said materials in mixed form are introduced into a flow of gaseous medium flowing at such a rate to carry off the lighter material but not the heavier material to achieve the separation.
  • Fig. 1 the apparatus is shown in perspective elevation, and will be seen to comprise a closed casing having a top 10, large side walls 12, 14, narrow end walls 16, 18, and a base 20, all defining a separation chamber.
  • a removable drawer 22 At the bottom end of the separation chamber is provided a removable drawer 22, and inside the separation chamber is a separation partition 24 which extends from the top 10 to a point approximately mid-way of the height of the separation chamber.
  • the top 10 is provided with an outlet 26 to which a source of suction is in use applied, whilst in the side wall 16 near the top 10 is provided an inlet 28 through which the air is drawn as a result of applying suction the outlet 26.
  • the inlet 28 is connected to a feeding structure 30 which comprises a feed chute 32 of tapering cross-section from top to bottom as shown in Fig. 2, and a lift channel 34.
  • the feed chute 32 is opened at the top to allow the insertion thereinto of the mixture of heavy grain and seed material, and the lighter chaff and feathers.
  • At the lower end of the chute 32 is an outlet 36 whereby the chute communicates with the lift channel 34 at the lower end thereof.
  • the lift channel 34 is open at the lower end 38 so that air can be drawn thereinto as indicated by arrow 40 so that a flow of air through the apparatus takes place as indicated by arrows 40, 42, 44, 46, 48 and 50.
  • any lighter material carried as indicated by arrows 48 and 50 out of the outlet 26 will only be very light dust.
  • the drawer 22 can be removed and the lighter material, in this case chaff and feathers, disposed of.
  • the appartus therefore works on a two stage separation process, the seed and grain dropping from the outlet 38 and the chaff and feathers being separated out in separation chamber.
  • the chute 32 can have its width controlled by means of a slidable plate 56 which can be slid in and out relative to the chute transverse direction as indicated by arrow 58.
  • the apparatus is simple in nature and yet highly effective in operation. Chaff and smaller feathers are caught in drawer 22 and are effectively separated from the more valuable grain which can be re-used.
  • the inlet of a vacuum cleaner may be connected to the outlet 26 to provide the suction force, but the equipment can be provided with its own suction fan and, if required, air filtering arrangement similar to a vacuum cleaner.
  • a fan may be located in the separation chamber where indicated by dotted lines 100, to provide a self contained unit.
  • the entire apparatus may be constructed in synthetics plastics material.
  • a blowing apparatus may be provided for blowing the air through the apparatus.
  • the apparatus is specifically designed for separating whole grain and seed (heavier materials) from feathers and chaff and dust (lighter materials) it can be used for separating the materials other than those specified.
