Definitions

  • the present invention relates to decomposition containers.
  • the invention primarily relates to decomposition latrines of the kind comprising a chamber with a heat source associated therewith, such as an electric heating element for heating excrement or other decomposable organic material in the. chamber.
  • the known decomposition latrine has a mode of operation such that, when the mass has partially decomposed and is to be removed from the chamber, a hatch must be opened in one side of the chamber, whereafter it is possible to use the stirring means to move decomposed material from the chamber and out through the opening uncovered by the hatch, so that the decomposed material falls down into a secondary chamber.
  • the partially decomposed material often contains certain types of sickness-generating bacteria, fly eggs and other unhygienic constituents however,, which are not desirable in the final product, since it is to be handled by people and possibly used as manure.
  • the wholly or partially decomposed material is subjected to heating in the secondary chamber, in the known decomposition latrine, to a temperature which is considerabl higher than the decomposition temperature used in the first chamber and which is intended to provide pasteurization.
  • Pasteurization is obtained at a temperature of about 55°C, although the temperature should preferably reach 67°C, at least for a short time, so that pasteurization is done rapidly.
  • Characteristic of the known decomposition toilet is thus that decomposition and pasteurization are done in two separate operations and in two separate chambers.
  • Decomposi- tion takes place at the temperature in the interval of 25 to 30 C, i.e. in the temperature range known as the mesophilic temperature range.
  • the decomposition process in the thermo- philic temperature range is many times quicker than that in the mesophilic.
  • the present invention has the object of providing a decomposition container or decomposition latrine, in which decomposition and pasteurization can be performed more simply and in a mode which is quicker and more effective than in the known decomposition latrine. This is achieved with a decomposition container which, according to the invention, is distinguished in that the heat source is provided to raise the temperature of the mass in the chamber to a value of between 45 and 80 C, enabling a rapid thermo-
  • CM . W WII philic decomposition process simultaneously as rapid pasteurization, the pasteurized portion of the mass being •- m ⁇ vabXe. from the.-region at. the heat source.-.with-.the..help of a stirring means, rotatable by means of an electric motor. 5 Since the stirring means in the container in accordance . with. the. invention-continuously o.r .intermittently stirs the mass in the chamber, the temperature in the portion of the mass lying in the vicinity of the heat source will have a temperature in the upper part of the thermophilic temperature
  • thermophilic temperature range e.g. about 50°C
  • the thermostat is thus adjusted so that it comes into action at an upper boundary temperature which is obtained when the temperature in the mass in the vicinity of the thermostat has risen to about 70 C, i.e. a temperature lying in the upper part of
  • thermophilic temperature range 25 the thermophilic temperature range, and at a lower boundary temperature attained when the temperature has dropped to • about 50°C in the mass in the vicinity of the thermostat, i.e. a temperature which lies in the lower part of the thermophilic temperature range.
  • a lower boundary temperature attained when the temperature has dropped to • about 50°C in the mass in the vicinity of the thermostat, i.e. a temperature which lies in the lower part of the thermophilic temperature range.
  • the thermostat actuates the switch means in such a way that the heating element is switched off, and the electric motor of the stirring means is connected in for effecting a predetermined rotation of the stirring means ' so as to stir the mass in the chamber.
  • the thermostat and its control by a conventional switc means are simple and cheap details of known embodiment, ' but the use of these details described above as a means for controlling .decomposition and pasteurization in the chamber signify a considerable simplification of the construction and maintenance of the container.
  • the user of the latrine does not need to come into contact with any unhygienic final product, since the pasteurization takes place here before emptying.
  • two heating elements are used, but in the decompo ⁇ sition container in accordance with the invention only one heating element need be used.
  • thermo philic -temperature range in contradistinction to the known container where decomposition takes place substantially in the mesophilic temperature range, and as a result hereof there is provided a quicker decomposition in the inventive container, which is thereby given greater capacity.
  • the stirring means performs effective stirring and mixture of the different ingredients of the mass.
  • the stirring means in accordance with the inventio is to advantage formed in a novel mode in relation to the stirring means in the known decomposition latrine.
  • the stirring means consists of a rotatable shaft provided with a plurality of radial pins serving as stirring members to stir up the mass in the chamber.
  • a stiring means is used instead which is distinguished.in that flat bar-shaped members are used as stirring members, said members- extending- between the end walls of the chamber and along a rotation surface close to the curved bottom of the chamber and substantially concentric therewith.
  • the flat bar-shaped members have a width several times geater than their radial thickness.
  • Such a stirring means in accordance with the invention can be made with bars having rectangular cross section. The number of bars is suitably in the region of six to twelve bars uniformly distributed around the rotation surface.
  • Such a stirring means results in a lower torque requirement than the known stirring means-, and provides effective mechanical transport of material saturated with urine and other liquid and located in the . lower portion of the mass.
  • the material which has ' fallen down into the box must be spread out with a rod so that it is evenly distributed in the box. Thereafter, according to the manufacturer's instructions, a small amount of water must be added to the box so that the heat supplied at the bottom thereof will be spread upwards in the pile of material. In order to retain the heat so that the tempera- ture at the surface will not be too low, the user must furthermore cover the box with an aluminium foil to preven heat transport from the unclean material in the box. After this, a timer must be turned to switch on the heating element for six hours. Only thereafter, after having becom cool, the material can be taken out-
  • emptying the latrine in accordance with the invention can be done in a substantially more simp and hygienic way. This is achieved in that the electric mot of the stirring means is coupled for alternatively driving either direction, i.e. its direction of rotation is revers ⁇ ible, which is enabled conventionally with the aid of a reversing switch.
  • the latrine in accordance with the invention is made in such a way that in the side wall forming part of the curved bottom of the chamber, there is an emptying opening.
  • the known toilet has however a stirring means which can only be rotated in one direction, namely in a direction from the bottom of the chamber and up to the emptying opening, which therefore mus be closed by a hatch during normal operation of the latrine .
  • No hatch is required in the inventive container, and the emptying opening can remain open even during normal operation.
  • the normal direction of rotation of the stirring means is such that the stirring members are moved away from the emptying opening and down towards the bottom of the chamber, so that the organic material in the chamber is transported away from the openin the whole time.
  • a collection chamber which can compris a box containing a collection bag.
  • This box thus consists o a separate part which can be taken out from the container i a simple way and thereafter it is easy to lift out the bag with the pasteurized material. After removing the bag, it can be closed so that the pasteurized material can be transported without the risk of dirtying.

  • a conventional thermostat 36 at the bottom of the chamber, for conventionally sensing the temperature in the mass at the bottom of the chamber.
  • the thermostat is disposed for energizing a switch to switch off the heating element 28.
  • the thermostat is thereby of such a nature that the tempera ture is allowed to sink to a lower boundary- temperature in the lower part of the thermophilic temperature range, e.g. about 50 C, where the heating element 28 is once again switched on for renewed heating.
