摘要:
A method and apparatus for use in pulverization and/or segregation which is suitable for obtaining the desired quality of the pulverized materials. Such pulverization is performed by restricting the discharge rate of the mixture through the discharge opening and thereby controlling the quantity and time the mixture remains within the pulverizer. The pulverizer is provided with a weir at the discharge end of the drum or cylinder for such restricting purpose. Also, beaters disposed within the pulverizer are provided with safety means enabling the beaters to pivot when a relatively stiff constituent is encountered in the mixture.
摘要:
An apparatus and a method for processing municipal waste with increased processing capacity are provided. The apparatus includes at least a cylindrical screen having ridge projections on the inner surface thereof and a group of beaters mounted on a central shaft extending axially through the cylindrical screen. In carrying out the method, the municipal waste charged into the cylinder receives powerful beating and shearing due to the interaction caused by the relative rotation between the tips of the beaters and the ridge projections thereby remarkably increasing the processing capacity.
摘要:
A composting method uses an "H"-shaped apparatus comprising four rotatable paddles disposed at each terminal end of the "H"-shaped arrangement, the apparatus as a whole being reversibly movable in the direction of the horizontal bar of the "H" shape. A plurality of composting sections are arranged in a row along and at opposite sides of the horizontal bar. The composting operation is performed for the plurality of sections according to a predetermined schedule so that, when the apparatus is under operation, four sections are simultaneously under operation, one of the four sections may be receiving material and three sections are simultaneously under agitation by the paddles and at the other section or sections the material may be taken away.
摘要:
An apparatus for composting materials suitable for composting such as kitchen refuse or municipal refuse, in which rotary agitator units are provided above a plurality of horizontal floors, respectively so that the agitator units themselves are rotated simultaneously when the material such as kitchen refuse is charged onto the uppermost stage of the horizontal floors, the agitator units and said horizontal floors also being rotated relative to each other during which the charged material is agitated and moved on the horizontal floors, and the material is allowed to fall successively onto the floor below thereby effecting the composting operation.
摘要:
A pyrolyzing apparatus having a pyrolysis fluidized bed chamber and an incineration fluidized bed chamber or chambers each directly adjacent and communicated with the pyrolysis fluidized bed chamber through an opening or openings in a partition wall above a common perforated bottom plate, the respective levels of the fluidized beds being controlled by regulating the pressure(s) in free board(s) of the fluidized bed chambers.
摘要:
Crude pulp stock is recovered from municipal waste by selectively pulverizing garbage (food waste) in the waste; removing the pulverized garbage; thence, moistening the rest of the waste so as to selectively weaken the materials, such as waste paper, usable as crude pulp stock; and taking out the pulverized crude pulp stock.
摘要:
A novel thermal reactor or incinerator of a fluidized bed type is provided wherein residua which have descended to the bottom of the fluidizing bed are transferred to a discharge opening by a plurality of hollow cylindrical rotors disposed above the bottom plate of a vessel of the reactor or incinerator, each of the rotors being provided with a plurality of perforations in the cylindrical wall through which gas or air is injected into inert solid or sand particles to form the fluidized bed.
摘要:
An apparatus is presented for effectively sorting and disposing of waste. Waste is sorted into three or more groups enabling post treatment or reutilization of the sorted waste with less possibility of environmental contamination. The apparatus comprises mainly a drum having a plurality of screen means and a plurality of rotatable reducing means, each of the reducing means facing a corresponding screen means, respectively and being driven at a properly selected speed depending on the constituents of the waste and the mesh size of the opposing screen.
