REFUSE STORAGE EQUIPMENT
BACKGROUND OF THE INVENTION
The present invention relates to a refuse storage equipment for temporary storage and timely discharge of general refuse or industrial wastes and, more particularly to a refuse storage tank suitable for medical waste intermingled with general and industrial wastes.
BRIEF DESCRIPTION OF THE PRIOR ART
The hitherto-known storage equipment of this type on a comparatively small scale comprises a tank body and, as disposed at the bottom thereof, a turntable, a screw conveyer or a scraper conveyer which, on actuation, discharges the refuse storaged in the tank body. The large-scale equipment of the prior art is a pit-and-crane system in which the refuse pooled in a pit is transferred to an incinerator by means of a crane.
However, when the small-scale equipment mentioned above is used, the refuse bags are readily broken during storage or during transfer to an incinerator and the consequent scattering of dirty wastes and leak-out of fouled water contaminate the tank and transfer equipment to bring a sanitary problem. This is particularly true with medical waste containing substances which are infective, injurious or liable to cause environmental pollutions. Because these substances are generally contained in vinyl bags, cartons or corrugated-board boxes, it is necessary to prevent the aforesaid contamination by minimizing the destruction of refuse packages prior to charging into the incinerator. ~

Because these substances are generally contained in vinyl bags, cartons or corrugated-board boxes, it is necessary to prevent the aforesaid contamination by minimizing the destruction of refuse packages prior to charging into the incinerator. ~
- 2 ~0193~4 The prior art equipment including a turntable, screw conveyer or scraper conveyer is generally so complicated in construction that in the event of a mechanical trouble the refuse pooled in the tank must be manually removed to have access to the delivery mechanism located underneath and this entails much labor and time.
Furthermore, in the case of refuses which vary widely in composition, particularly medical waste including wastes of high calorific value such as plastic and cotton products, etc hardly combustible materials such as paper diapers, excised organs, etc. and non-combustible materials such as metal and glass instruments and ware, they cannot be burnt in stable combustion state if charged into the incinerator without mixing. Thus, such refuses cannot be completely burnt for sterilization and environmental pollution control.
SUMMARY OF THE INVENTION
It is an object of the present invention to overcome the above-mentioned disadvantages of the prior art refuse storage 2~ equipment and provide an improved refuse storage equipment wherein the refuse is discharged under its own weight without being subjected to undue mixing, tearing or compression and hence with a minimum of contamination of the tank and surroundings and involving a reduced risk of environmental pollution and injury to personnel.
It is a further object of the invention to provide a refuse storage equipment which is simple in construction and less liable to develop a fault or failure, can be easily maintained and repaired and ensures facilitated discharge of the refuse.

It is still another object of the invention to provide a refuse storage equipment comprising a delivery system installed under a discharge port of the tank body wherein the speed of this delivery system and the timing of actuation of dampers are controlled in correlation to ensure a continuous transport of the refuse to an incinerator to thereby suppress any sudden change in the state of combustion and attempt stabilizing the state of combustion in the incinerator.
BRIEF DESCRIPTION OF THE DRAWINGS
Fig. l is a schematic front sectional view illustrating the construction of the refuse storage equipment of the invention; and Fig. 2 is a sectional side elevation view showing the construction of the refuse storage equipment according to the invention.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
The refuse storage equipment of the present invention is illustrated in Figs. l and 2. Referring to Figs. l and 2, the reference numeral l represents a storage tank having a charging hopper 11 and a discharge port 12. The internal space of the tank l is divided by a vertical longitudinal partitioning plate 2 and a vertical transverse partitioning plate 3 into four storage chambers 5. Disposed below each of these storage chambers is a double damper means consisting of an upper damper 6 and a lower damper 7. Thus, the upper damper 6 and the lower damper 7 divide an upper storage compartment 5l and a lower storage compartment 52 within the 3~ storage chamber 5.
201938~
The upper damper 6 is disposed to be movable transversely in horizontal direction by a driving unit 61. The upper damper 6 is normally projecting into the corresponding storage chamber 5 to close the chamber 5. As the storage chamber 5 is thus closed by the upper damper 6, the refuse dumped from the charging hopper 11 is piled up in the storage compartment 51.
The aforementioned driving unit 61 is provided with a pressure gauge 611. This pressure gauge measures the reaction of the upper damper 6 against the refuse while the upper damper 6 is caused to project into the storage chamber 5. The driving unit 61 is constructed so that it stops the projecting motion of the upper damper 6 when the reading of the pressure gauge 611 exceeds a predetermined value. By stopping the projecting motion of the upper damper 6 in this manner, the breakage of refuse packages can be minimized. In order to prevent the refuse to fall down, the upper damper 6 need not completely close the storage chamber 5. Rather, it is sufficient to stop the projecting motion of the upper damper 6 with a pressure not so great as crushes the refuse packages.
The lower damper 7 is rotable by a driving unit, not shown, to selectively assume a horizontal position or an inclined position as indicated by the two dotschain line.
The lower damper 7 closes the bottom of the storage chamber 5 when it is held in the horizontal position and the refuse falling down upon opening of the upper damper 6 piles up in the lower storage compartment 52.
The upper storage compartment 51 of each storage chamber 5 is provided with a plurality of level gauges 511. These 20193~
level gauges 511 are adapted to sense the amount of refuse accumulated in the respective upper storage compartments 51 to provide information which can be used for monitoring the charging and discharging statuses of the refuse storage equipment. Based on the information provided by these level gauges 511, it is possible to actuate a warning or alarm means and thereby control the charging of refuse.
Disposed under the discharge port 12 of the storage tank 1 is a conveyance system 8. The conveyance system is intended 1~ to transport the refuse discharged from the discharge port 12 of the storage tank 1 to an incinerator which is not shown, with the conveyance path ending close to the charging hopper of the incinerator.
The reference numeral 81, in Figs. 1 and 2, represents guide rollers provided on the conveyance system 8 for smooth driving of the system 8.
The operation of the above refuse storage equipment is explained below.
Referring to Fig. 1, each of the upper dampers 6 is set in projecting position and each of the lower dampers 7 in horizontal position to close the storage chambers. As the storage chambers 5 are charged with refuse from the charging hopper 11 in the above condition, the refuse is accumulated in the upper storage compartments 51 of the storage chambers 5. As the upper damper 6 is retreated from the corresponding storage chamber 5, the lower part of the refuse accumulated in the upper storage compartment 51 falls onto the lower damper 7 and is piled up in the lower storage compartment 52. Then, as the upper damper 6 is caused to project into the storage 3~ chamber 5, the refuse in the storage chamber 5 is distributed 20~938~
into the upper storage compartment 51 and the lower storage compartment 52. In this condition, the lower damper 7 is swung into the inclined position. Then, the refuse in the lower storage compartment 52 falls through the discharge port 12 onto the conveyance system 8 and is thence carried thereby to the incinerator. Thus, after discharge of the refuse, the lower damper 7 is swung back into the horizontal position and the upper damper 6 is opened as described above, whereupon a further refuse is piled up in the lower storage compartment 52.
Since the refuse is discharged under its own weight in this invention, there occurs no forced mixing, tearing or compressive breakage of refuse packages. Consequently, the refuse packages are scarcely destroyed and consequently the fouling of the interior of the storage tank 1 and around the discharge port 12 is minimized. This is not only desirable from sanitation points of view but is conducive to a reduced risk of pollution and injury to the personnel. Particularly when medical refuses are involved, the infection fo personnel due to the contaminant bacteria and the like can be effectively prevented.
Furthermore, while the refuse is intermittently discharged onto the conveyance system 8 according to operation of the upper dampers 6 and lower dampers 7, it is possible to effect a continuous and average charging of the incinerator with the refuse by controlling the timing of discharge from the lower damper 7 and the travelling speed of the conveyance system in correlation and thereby ensure a stabilized combustion of refuse in the incinerator.
Furthermore, the refuse may be selectively stored in the plurality of storage compartments 5 according to its type or 20~93~4 composition and by discharging different kinds of refuse from the respective storage compartments 5 in a suitable combination, it is possible to effect the uniformity of quality of the refuse to be fed to the incinerator and thereby suppress any violent fluctuation in the state of combustion for a further improvement of operation.
While, in this embodiment, the interior of the storage tank l is divided by the vertical longitudinal partitioning plate 2 and vertical transverse partitioning plate 3 into four 1~ storage chambers, the storage tank space may be divided into any other suitable number of chambers. For example, when the capacity of the storage tank is small or the variation in refuse composition is small, the interior of the storage tank need not be divided. Moreover, the mode of operation of the upper damper 6 and the lower damper 7 may each be whichever of the horizontal shift type and vertical swing type described hereinbefore.
Furthermore, in the case of refuses which vary widely in composition, particularly medical waste including wastes of high calorific value such as plastic and cotton products, etc hardly combustible materials such as paper diapers, excised organs, etc. and non-combustible materials such as metal and glass instruments and ware, they cannot be burnt in stable combustion state if charged into the incinerator without mixing. Thus, such refuses cannot be completely burnt for sterilization and environmental pollution control.
