Description

- 1 AUSTRALIA PATENTS ACT 1990 COMPLETE SPECIFICATION FOR A STANDARD PATENT ORIGINAL Name of Applicant/s: Ching Yuan Huang Actual Inventor/s: Ching Yuan Huang Address for Service is: SHELSTON IP 60 Margaret Street Telephone No: (02) 9777 1111 SYDNEY NSW 2000 Facsimile No. (02) 9241 4666 CCN: 3710000352 Attorney Code: SW Invention Title: MIXER INTEGRATED WITH HEATERS The following statement is a full description of this invention, including the best method of performing it known to me/us: File: 67570AUP00 -2 MIXER INTEGRATED WITH HEATERS FIELD OF THE INVENTION The present invention generally related to a mixer for mixing materials. More 5 specifically, the present invention relates to a mixer integrated with heaters. BACKGROUND OF THE INVENTION Any discussion of the prior art throughout the specification should in no way be considered as an admission that such prior art is widely known or forms part of common 10 general knowledge in the field. At the present time, there is an ever-increasing trend in the direction of solar energy utilization for both electrical power generating and heating purposes. This invention is concerned with a mixer utilizing solar energy and hot water heater for the purpose of providing a mixer having a uniform temperature distribution. 15 AU Patent Application No. 2009245819, assigned by the same assignee of this application, discloses a continuous mixer. This mixer does not have any heating means for expediting the reaction rate of the material within the mixer. SUMMARY OF THE INVENTION 20 It is an object of the present invention to overcome or ameliorate at least one of the disadvantages of the prior art, or to provide a useful alternative. Accordingly, the present invention provides a mixer comprising a slant cylinder formed of an elongated container with an upper portion and a lower portion and extending from an upstream end to a downstream end, an inlet provided near the 25 upstream end for introducing a material into the cylinder, an outlet provided near the downstream end for discharging the material, and a helical screw provided within the cylinder for mixing the materials; and a driving motor having a shaft engaged with the helical screw for providing the power for mixing, wherein the elongated container is provided with a hot water heater extended longitudinally on the lower portion of the 30 elongated container and a solar heat collector provided longitudinally along the upper portion of the elongated container. Unless the context clearly requires otherwise, throughout the description and the claims, the words "comprise", "comprising", and the like are to be construed in an - 3 inclusive sense as opposed to an exclusive or exhaustive sense; that is to say, in the sense of "including, but not limited to". Advantageously, the invention, at least in a preferred form, provides a machine for mixing material and heating material in a uniform manner. 5 Although the invention will be described with reference to specific examples it will be appreciated by those skilled in the art that the invention may be embodied in many other forms. BRIEF DESCRIPTION OF THE DRAWING 10 A preferred embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings in which: FIG. 1 is a plan view of a mixer with heaters according to this invention; FIG. 2 is a cross-sectional view of the mixer shown in FIG. 1, taken along the lines 2-2 of FIG 1; 15 FIG 3 is a top view of the mixer shown in FIG. 1; and FIG. 4 is a cross-sectional view of the mixer shown in FIG. 3, taken along the lines 4-4 of FIG. 3. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 20 FIG. I represents a schematic view of the continuous mixer with parts broken away to show the appearance of the screw within the continuous mixer 100 in accordance with the invention. The continuous mixer 100 shown in FIG I generally consists of a slant cylinder 10 and a driving motor 90. The slant cylinder 10 is generally formed of an elongated container 12 with an 25 upper portion 11 and a lower portion 13 and extends from an upstream end 91 to a downstream end 93. The slant cylinder is further provided with an upstream inlet 92 near the upstream end 91 for introducing material into the cylinder 10 and a downstream outlet 94 near the downstream end 93 for discharging the mixed material. A helical central screw 20 is provided within the container 12 for mixing materials. The helical 30 central screw 20 includes a stem 22 having two ends each rotatably mounted to an end of the cylinder 10 and a helical screw blade 24 attached on the stem 22. The driving motor 90 has a shaft 96 connected to one end of the stem 22 for conveying materials along the cylinder 10 from upstream end 91 to the downstream end 93 with rotation of the screw -4 20. As shown in FIG. 1, the cylinder 10 is further provided with a hot water heater 30 extended longitudinally along the lower portion 13 of the elongated container 12. Within the hot water heater 30, a hot water flow is directed from the upstream end 91 to the 5 downstream end 93 of the elongated container 12 by a pump (not shown) for heating the material within the cylinder 10. The hot water heater 30 is further provided with an outlet pipe 32 near the downstream end 93 for discharging the heat-exchanged water. Positioned on the outlet pipe 32 is a valve 34 for regulating the flow rate of the hot water flow. 10 Referring to FIG. 2, the hot water heater 30 is a water tank of semi-circular in transverse cross section of the elongated container such that the material at the lower portion 13 of the cylinder 10 is uniformly heated by the hot water heater 30 when the material is conveyed from the upstream end 91 to the downstream end 93 (shown in FIG. 1). The hot water heater 30 is further provided with an inlet pipe 36 near the upstream 15 end 91 (shown in Fig. 1) for supplying hot water into the hot water heater 30. Positioned on the inlet pipe 36 is a check valve 38 for ensuring the hot water flows in a proper direction. A solar heat collector 50 is provided longitudinally along the upper portion 11 of the elongated container 12. In FIG. 2, the solar heat collector 50 is consisted of two 20 elongated heating chambers 52, 54 on the transversely opposite sides of the elongated container 12. Each of the heating chambers 52, 54 is formed of an inclined sidewall 56, 58, a vertical insulation wall 62, 64 for insulating the heating chamber 52, 54 from the container 12, and a transparent cover 66, 68. The sidewall 56, 58, the vertical insulation wall 62, 64 and the transparent cover 66, 68, these parts are combined together as to 25 form the heating chamber 52, 54 of an elongated triangular shape in transverse cross section. The inclined sidewalls 56, 58 are preferably painted black to absorb heat energy from the sun. In FIG. 3, on the top of the transparent cover 66, 68, three air conduits 72, 74, and 76 are provided for communicating the heating chamber 52, 54 with the interior of the 30 elongated container 12. The elongated container 12 is provided with a ventilation unit 80 which opens into the atmosphere. A thermostat 39 provided within the hot water heater 30 may be utilized to control the internal temperature of the hot water heater 30. As shown in FIG. 4, when the solar heat collector 50 is operated, the sunlight -5 impinges upon the inclined sidewall 56, 58 and the dry hot air produced by the solar heat is introduced into the elongated container 12 via the air conduit 74 for heating the material within the container 12 in a flow as shown by arrows, and then the dry air passed through the material to be heated is exhausted from the ventilation unit 80 5 (shown in Fig. 3). Since the elongated container 12 is surrounded by the hot water heater 30 and the solar heat collector 50, the temperature within the elongated container 12 can be increased by solar heat so that the material within the elongated container 12 is effectively heated. 10 While a preferred embodiment of the present invention is shown and described, it is envisioned that those skilled in the art may devise various modifications of the present invention without departing from the spirit and scope of the appended claims.
