The present invention is an air transfer type automatic waste disposal system in which wastes introduced into a conduit separated from the outside are automatically collected by internal air flow, and particularly, a structure capable of automatically collecting food waste by generation in real time from a sink. The present invention relates to an automatic food waste disposal device for each generation.

As the residential environment has evolved into modern apartment complexes or high-rise residential complexes, the scale of household waste has also increased astronomically, and accordingly, the existing garbage collection, which periodically collects garbage collected at a certain place, is collected. There is a limit to the process.

For more advanced garbage collection methods suitable for large residential complexes, the transport pipes are isolated from the outside from the building to the garbage collection site, and the garbage collected through the transport pipes is piggybacked on the internal air flow to collect garbage automatically. Background Art An automated transport system for waste disposal is known which allows transportation to a location.

FIG. 1 is a view showing an example of a conventional air transfer type automatic waste disposal system, in which a garbage inlet 2 is disposed on each floor of a building in a group residential area, and the garbage inlet 2 is divided by each household and extended. It is connected to the conveying conduit 6 via the single pipe 4, and the waste to be introduced is a system which is sent to the collection area 8 provided on the end side of the conveying conduit 6 for processing.

This air transfer type automatic waste disposal system transports garbage bags into the collection area by air flow from the sealed transport line to be collected. Therefore, it does not leak unpleasant odors or other contaminants around the residential area. Although there is an advantage that it can be collected hygienically and completely, there are difficulties in handling food wastes that occur daily in generations.

In other words, food waste by generation is mostly left over from food scraps or ingredients, and if it is collected until it becomes an amount that can be put in an envelope, corruption progresses and causes unsanitary problems.

This problem can be a source of mold and contaminate the air filter of air conditioning facilities, especially in a residential residential complex that operates as a central air conditioning system.

Therefore, it is preferable to collect the food waste by generation in a bag or the like, and collect it in real time through a dedicated air transport generation food waste automatic disposal system.

The present invention is to solve the problems encountered in the conventional air transfer type automatic waste disposal system described above, it is possible to process the food waste by generation in the sink in real time, in addition to be able to penetrate the pipe clogged with food waste The purpose of the present invention is to provide an automatic food waste disposal apparatus for each generation.

According to the above object, the present invention should be able to suction-collect food waste generated by generations using the air flow directly from the sink, and to prevent the smell of food waste in the kitchen, If it is blocked, it should have its own first aid and drill function.

In the present invention, an object of the present invention is an air transfer type automatic waste disposal system in which waste disposed by a waste inlet is sucked and transferred to an air flow in a pipe to be disposed of in a collection area, and a space communicating with outside air only through a check valve is provided inside. A food waste inlet opening and closing with a lid is provided in the space of the sink, and the lower end of the plant waste inlet communicates with the suction pipe via a gate valve arranged at predetermined intervals, while connecting with the front end of the gate valve. In the position where the through hole in the circumferential surface of the basket is arranged around the lower end of the food waste inlet, and in the middle of the suction pipe is a water supply pipe with a water supply tube with a water supply solenoid valve and a supply pipe with an air supply solenoid valve integrally Compressed in the middle of the suction pipe in connection communication It is possible to supply air / water, and also to install a shut-off gate valve in each section of the transfer pipe that receives household waste from the suction pipe, and a pressurized tube with a pressurized solenoid valve and an outside air supply line with an outside solenoid valve. Compressed air engines connected integrally can be implemented as a device of connection and communication for each section of the transfer pipe.

In the apparatus of the above-described configuration, it is preferable that the compressed air engine be connected in a normal line direction perpendicular to the center radial direction of the feed pipe.

Hereinafter, the present invention will be described in detail with reference to preferred embodiments according to FIGS. 2 to 4.

Fig. 2 is a cross-sectional view showing the configuration of the main part of the apparatus of the present invention, showing the food waste inlet 12 provided in the sink 10 and the component portion adjacent thereto.

The food waste inlet 12 includes a structure in which the inlet side is opened and closed by the lid 14, and the lower end thereof extends to a position adjacent to the front end side of the gate valve 16 to be replaced at a predetermined interval. .

The lower end of the food waste inlet 12 is surrounded by a basket 18 connected to the gate valve 16. In the upper half of this basket 18, the through hole 20 is innumerably opened so that outside air can pass through.

A suction pipe 22 that sucks food waste for each generation is connected to the lower side of the gate valve 16 to extend below the sink 10, and the water supply pipe 24 is in communication therebetween.

The water supply pipe 24 has a water supply pipe 30 drawn in via a portion of the first T-shaped pipe 26 and the water supply solenoid valve 28 from the outside, and also the other of the first T-shaped pipe 26 from the outside. And the air supply solenoid valve 32 and the air supply pipe 36 drawn in via the second T-shaped pipe 34 are connected to each other, and the other side of the second T-shaped pipe 34 is a pneumatic line. In communication with (38), compressed air can be supplied to the cylinder (40) operating the gate valve (16).

In the present invention, the water supply pipe 30 can be easily provided with a water supply capability by communicating with the peripheral water pipe (not shown) of the sink 10. However, the air supply pipe 36 must be connected to an output end 42 extending from a conventional compressor (not shown) to have air supply capability.

The compressor for generating compressed air may employ a small capacity compressor that can be installed for each generation, or use one or several large capacity compressors that can be shared by all households in a designated place of a building.

In the apparatus of the present invention, the inside of the sink 10 should form a space isolated from the outside, the suction pipe 22 and the water supply pipe 30 and the air supply pipe 36 disposed in the space extends to the outside Are all hermetically sealed, while the lower side of the sink 10 has a check valve 44 which opens only in the direction of receiving outside air, and smells of food waste per generation from the inside of the sink 10. It should be structured so that outside air can be distributed to the space without leaking.

The suction pipes 22 extending to the lower side of the sink 10 are arranged to be branched for each generation, and their ends are connected to the transfer pipe path 46.

In the present invention, the conveying pipe 46 is to provide a passage for allowing the generation of food waste to be transported by air flow, which is interposed with a blocking gate valve 48 for opening and closing the passage as shown in FIG. have.

The shut-off gate valve 48 is arranged in a predetermined area divided into several parts over the entire length of the transfer pipe 46, and the rear end of each shut-off gate valve 48 is a constant distance, for example, of the transfer pipe 46 It is connected with the bending pipe | tube 50 arrange | positioned every 100-200m intervals on the way.

A compressed air engine 52 is connected to the inlet side of the bent pipe 50, and the compressed air pipe 52 has a pressurized pipe 58 having a pressurized solenoid valve 54 and a pressurized manual valve 56, and an external air solenoid valve ( 60 and an external air supply pipe 64 having an external air manual valve 62 are connected together with a third T-shaped pipe 66.

The pressure pipe 58 is connected to the output end 42 of the compressor (not shown), and the air supply pipe 64 is in communication with the atmosphere. In addition, the pressurized solenoid valve 54 and the outside air solenoid valve 60 must be set so as to operate opposite to each other when one side is opened, and the other side is closed when the compressed air is supplied. You can get the effect of communicating with.

In addition, when the pressurized solenoid valve 56 and the external air solenoid valve 62 fail in the pressurized solenoid valve 54 and the external air solenoid valve 60, respectively, the said pressurized pipe 58 or the external air supply line 64 is closed. They are added for release and they are normally left open.

Reference numeral 68 of FIG. 2 is a sensor for detecting the amount of food waste for each household introduced into the food waste inlet 12, and another non-reference numeral 70 is an operation sequence of the solenoid valve and the gate valve provided in the present invention. The control unit for controlling, and the other reference numerals 72, 74 are respectively installed in the suction pipe 22 and the transfer pipe 46, the suction side negative pressure sensor and the collection side negative pressure sensor for detecting the internal pressure, where the collection side negative pressure sensor In fact, 74 is actually arrange | positioned for the area | region which divides the conveyance line 46 by arbitrary length.

The apparatus of the present invention having such a configuration operates as follows.

Prior to operation, the gate valve 16 of the suction pipe 22, the feed water solenoid valve 28, the air supply solenoid valve 32, and the pressurized solenoid valve 54 attached to the feed passage 46 are closed and the feed passage 46 The shut-off gate valve 48 and the outside electromagnetic solenoid valve 60 are placed in an open state, and air flow is generated inside the transfer pipe 46.

Generational food waste generated in the kitchen opens the lid 14 exposed to the top surface of the sink 10 is disposed in the food waste inlet 12 and the lid 14 is closed again.

When the sensor 68 detects the input food waste for each generation and sends a garbage input signal to the controller 70, the controller 70 operates the cylinder 40 to open the gate valve 16.

When the gate valve 16 is opened, the internal air of the sink 10 is sucked into the suction pipe 22 so that the air pressure drops, which causes the check valve 44 to naturally open and the outside air as shown by the arrow of FIG. (18) passes through the through hole (20) and begins to be sucked into the suction pipe (22), the food waste per generation put into the food waste inlet (12) by the air flow accompanying the external air suction action is the gate valve (16) Passed through the suction pipe 22 is sucked and transported through the transfer pipe 46 is collected.

The transport state of the food waste collected for each generation can be grasped by the detected values of the suction side negative pressure sensor 72 and the collection side negative pressure sensor 74.

That is, when the suction pipe 22 is blocked by the food waste for each generation, a local pressure change occurs in the pipe, and the suction side negative pressure sensor 72 detects this and inputs a pressure abnormal signal to the controller 70.

At this time, when the signal of the suction side negative pressure sensor 72 is input, the controller 70 drives the cylinder 40 in reverse to close the gate valve 16, and opens the air supply solenoid valve 32 to the suction pipe 22. By distributing food, household wastes that block the building are pushed out.

If the controller 70 does not receive the normal pressure signal from the suction side negative pressure sensor 72 even though the compressed air is supplied for a predetermined time, for example, 10 seconds, this time, the water supply solenoid valve 28 is opened and compressed. Allow water to be supplied with the air.

The supplied water is applied to clogged food waste by generation, which makes it soft and humidified, and forms a water film at the inner edge of the pipe to prevent pressure leakage of compressed air. As a result, clogged food waste is pushed back. The blockage of the suction pipe 22 is eliminated by being guided to the outgoing feed pipe 46.

In addition, this effect is shown equally in the conveyance pipe 46. FIG.

That is, when the inside of the conveying pipe 46 is blocked by food waste for each generation, the pressure change generated thereby is detected by the collecting side negative pressure sensor 74 so that a pressure abnormal signal is input to the controller 70, and the controller ( 70 recognizes the zone where the pressure change occurred in the transfer line 46 by comparing the input signal with the built-in address information, closes the shutoff gate valve 48 and the outside air solenoid valve 60 in the corresponding zone, and pressurizes the electronic By opening the valve 54 to supply compressed air, the blocked food waste is pushed out.

Typically, since the conveying pipe 46 is to be a tube of a larger diameter than the suction pipe 22, it is hardly clogged, and even if clogged, the compressed air can be pushed out with only compressed air. However, in the bent portion of the bending pipe 50, the food waste residues of each generation stay mixed with water, but this acts as a barrier to prevent the spread of food waste smells by generations, and the compressed air pipe 52 When pressurized by the compressed air supplied through the hermetic movement through the entire cross-section of the conveying pipe 46, pressurized space in the role of a piston, the food waste blocked by generation is effectively pushed out, It will eliminate the clogging phenomenon.

In addition, when the compressed air pipe 52 is arranged in a normal direction orthogonal to the radial direction of the bent pipe 50, as shown in FIG. 4, the compressed air supplied is carried on the inner surface of the bent pipe 50 by luminance. The vortex pressurizes the food waste by generations, thereby realizing more effective extruding.

The above-described embodiment shows an example in the case of using a relatively small facility, and in the case of a large-scale facility, an appropriate number of temporary storage tanks (not shown) may be interposed in the middle of the delivery pipe 46.

As described above, according to the present invention, since it is possible to collect household waste directly from the sink without putting the garbage in the bag, it is effective in ensuring sanitary life in a multi-purpose building and the like, and does not cause pollution of the air conditioning facilities of the building. There is.

In addition, since the collection passage is blocked by food waste by generations, it also detects this and automatically supplies compressed air and water so that it can be handled by itself.
