[0002]
[Prior art]
2. Description of the Related Art Conventionally, a soot processing machine has been known in which the soot such as raw garbage is dried to prevent it from being spoiled and the odor component generated during the processing is deodorized. In general, such a soot treating machine is configured to deodorize and discharge water vapor generated by heating the soot.
[0003]
Since garbage is generated mainly in the kitchen, it is convenient to install a slag treatment machine indoors, but there are many factors that worsen the indoor environment such as odor leakage, increased humidity due to discharge of water vapor, and increased temperature due to heat sources, Indoor installation was difficult. Therefore, the applicant of the present application includes a heating chamber that heats the soot and a condensing chamber that cools and condenses the steam by blowing air from an external fan, and the heating chamber and the condensing chamber are heated by the steam generated by heating the soot. An invention has been proposed in which the space is sealed in a state where air existing in the communicating space is pushed out, and the amount of condensation of water vapor is increased to dry the sealed space with a negative pressure. In such a configuration, odor leakage from the sealing portion with the lid can be prevented by negative pressure, and the heating amount can be reduced by lowering the boiling point. Moreover, it is not necessary to discharge odor and water vapor by draining the odorous components generated from the soot into the sewer pipe together with the condensed water, and can be used indoors.
[0004]
[Problems to be solved by the invention]
In such a configuration, it is important to efficiently condense the water vapor generated from the soot, but there is a problem that if the air is blown by a fan from the outside in order to increase the cooling efficiency, the structure becomes complicated and the cost increases. It was.
An object of the soot treating machine of the present invention is to solve the above-mentioned problems and to improve the cooling efficiency of water vapor with an inexpensive configuration.
[0005]
[Means for Solving the Problems]
The soot treating machine according to claim 1 of the present invention for solving the above-mentioned problems is
A heating section for heating straw such as raw garbage;
A condensing unit that communicates with the heating unit and cools a gas containing water vapor generated from the soot;
A drainage channel for draining the water condensed in the condensing unit to the outside ;

[0011]
Furthermore, coagulation in the flow path from the reduced portion to the drainage to form a condensed puddle for storing water, gas drainage and gas condenser portion by the water while the water collected in the condensate puddle exceeds a predetermined sealing level The communication space between the heating chamber and the condensing chamber is sealed by blocking the flow path that communicates with the heating chamber. In this sealed space, the soot is heated and the generated water vapor is condensed to prevent the uncondensed water vapor from being discharged to the outside as it is. In addition, water condensed in the condensing unit is sent to the condensate pool, but the water accumulated in the condensate pool is drained from the drainage channel to the outside (for example, sewer pipes) beyond the predetermined drainage water level. It will not continue to increase. In addition, when the pressure in the sealed space becomes negative compared to the drainage channel, the water level on the drainage channel side of the condensate pool falls and the water level on the condensing unit side rises, but the water level on the drainage channel side falls to a predetermined sealed water level. Since the air on the drainage channel side is sucked into the sealed space, it is possible to prevent the water level on the condensing unit side from rising too much.
[0008]
Garbage disposer according to claim 2 of the present invention to solve the above problems is the garbage disposer of claim 1 Symbol placement,
A return means forcibly returning the gas cooled in the condensing unit to the heating unit;

[0009]
In the soot treating machine according to claim 1 of the present invention having the above-described configuration, the soot such as garbage is heated in the heating unit to evaporate water contained in the soot, and the gas is produced in the condensing unit communicated with the heating unit. Cool and condense the water vapor. This condensing part overlaps at least one plate with two dents, seals the periphery of the plate to create a space inside, and forms a plurality of partition walls in the space to meander the gas To be guided. Therefore, the gas from the heating unit is meandered and guided in the condensing unit, and the inner surface of the plate and the water vapor are easily brought into contact with each other, so that the cooling efficiency can be increased. Moreover, most of the odor generated from the soot can be drained to the outside (for example, a sewer pipe) together with the condensed water.
[0010]
Moreover, because it is installed so the plate is vertical to guide by meandering gas in the vertical direction, it is possible to easily flow upward through the draft force along the external air to the outer surface of the plate, Cooling efficiency can be increased. Further, when water vapor condenses in the meandering flow path and becomes water, it immediately flows down along the vertical plane. Here, simply forming a meandering channel causes water to accumulate in the lower part of the channel and block the gas channel. Since the communication space is formed in the lower part by the structure in which the both end opening partition walls are lower than the lower end opening partition wall, the water flowing down from the meandering channel can be collected in one place and guided to the drainage channel, and In the state where the water level of the accumulated water is higher than the lower end of the both-end opening partition wall, the gas can be guided by meandering while preventing the gas from flowing from the communication space.
[0012]
In the following, garbage disposer according to claim 2 of the present invention having the above structure, forcing back the cooled gas in the condensing section to the heating section. For this reason, a gas containing a large amount of water vapor in the heating part flows smoothly to the condensing part, and a gas cooled by the condensing part and having a reduced water vapor content flows smoothly to the heating part. The water vapor evaporates well and the water vapor is condensed efficiently. Moreover, evaporation of the water | moisture content contained in a soot is accelerated | stimulated by blowing the gas sent back to the heating part toward the soot.
[0013]
DETAILED DESCRIPTION OF THE INVENTION
In order to further clarify the configuration and operation of the present invention described above, preferred embodiments of the soot treating machine of the present invention will be described below.
FIG. 1 is a schematic configuration diagram of a soot processing machine as an embodiment of the present invention. This dredging machine is roughly divided into a heating unit 10 for heating the garbage A, a condensing unit 20 for condensing water vapor generated from the garbage A, a condensing unit 20 and the sewage pipe 1 communicating with each other for drainage and storage. It consists of a blocking drainage unit 30 that blocks ventilation according to the state of water, and a return unit 40 that sends the gas cooled by the condensing unit 20 back to the heating unit 10 again.
[0014]
The heating unit 10 includes a processing tank 11 that stores the garbage A, a processing tank heater 12 that heats the processing tank 11, and a heating chamber 13 that has a heat insulating structure that stores these. In addition, a lid 13 a that opens and closes in order to take in and out the processing tank 11 is formed in the upper part of the heating chamber 13.
[0015]
As shown in FIG. 2, the condensing unit 20 overlaps two metal plates 21 and 22 each having a recess having a predetermined shape, and seals the periphery of the metal plates 21 and 22 by seam welding to create a space inside. In this space, lower end opening partition walls 23, 23,... Having only the lower end opened and both end opening partition walls 24, 24,. The lower ends of the both-end open partition walls 24, 24,... Are formed at positions lower than the lower ends of the lower-end open partition walls 23, 23,. Only the lower end opening is closed, and a flow path for guiding the gas by meandering in the vertical direction is formed. Further, the bottom surface of the lower communication space is inclined downward toward the shut-off drain portion 30 to facilitate the flow of water.
[0016]
In addition, by installing the metal plates 21 and 22 so as to be vertically oriented, external air smoothly flows upward along the outer surface by the draft force, so that the cooling efficiency can be increased. Furthermore, since the partition wall meandering in the vertical direction is formed, the water condensed in the flow path tends to flow down by the vertical surface. Here, when only a flow path that is meandered in the vertical direction without providing a communication space in the lower part is formed, water condensed in the flow path accumulates and increases, thereby blocking the gas flow path. By forming the communication space, water condensed in the flow path can be sent to the blocking drainage unit 30 side, and by closing the communication space with the accumulated water, gas can meander and flow.
[0017]
The cutoff drainage unit 30 includes a tank 31 for storing water, a condensed water discharge pipe 32 that hangs down on the bottom surface of the tank 31 and flows the water from the condensation unit 20 downward, and an upper side surface of the tank 31 and the sewage pipe 1. A drain pipe 33 that drains water in a tank 31 that exceeds a predetermined water level d to the sewer pipe 1. With such a configuration, in a state where the water in the tank 31 is higher than the water level e which is the lower end opening surface of the condensed water discharge pipe 32, the space where the gas communicates between the heating chamber 13 and the condensing unit 20 is exposed to the outside. Seal against.
[0018]
The return unit 40 forms a return pipe 41 that communicates the downstream side of the condensing unit 20 and the heating chamber 13, and the return pipe 41 includes a fan 42 that allows gas to flow from the condensing unit 20 toward the heating chamber 13, and a fan A gas heater 43 that heats the gas on the downstream side of 42 and a nozzle 44 that injects the gas from the downstream end toward the garbage A in the heating chamber 13 are provided.
[0019]
Next, the operation of this soot processor will be described. When the garbage A is put into the treatment tank 11 and the drying operation is started, the treatment tank 11 is heated by the treatment tank heater 12. Therefore, the temperature in the processing tank 11 and the heating chamber 13 rises, the moisture contained in the garbage A evaporates, and the pressure in the space where the gas in the heating chamber 13 and the condensing unit 20 communicates rises. And when the water of the condensed water discharge pipe 32 descends to the water level e which is the lower end opening surface, as shown in FIG. 3, the air present in the heating chamber 13 and the condensing part 20 is pushed out to the sewer pipe 1 side. The pressure increases only to a pressure determined by the water level difference between the tank 31 and the condensed water discharge pipe 32. On the other hand, when a predetermined time elapses after the heating by the treatment tank heater 12 is started, the fan 42 and the gas heater 43 of the return unit 40 are operated. Therefore, the gas containing a large amount of water vapor in the heating chamber 13 flows into the condensing unit 20, is cooled when flowing meanderingly, and is sent back to the heating chamber 13 through the return pipe 41. At that time, since the gas sent from the heating chamber 13 to the condensing unit 20 is cooled and the dew point is lowered, the water vapor contained in the gas is condensed and becomes water, and accumulates in the lower part of the condensing unit and flows down to the condensed water discharge pipe 32. Then, the amount of heat given by the heating chamber 13 is made smaller than the amount of heat taken by the condensing unit 20 to increase the amount of water vapor condensation, so that the pressure in the heating chamber 13 and the condensing unit 20 decreases, and water is accumulated in the tank 31. Therefore, the gas communication space between the heating chamber 13 and the condensing unit 20 is in a sealed state with respect to the outside, and a part of the air that was present at the start of operation is pushed out to the sewer pipe 1 side. Negative pressure can be set.
[0020]
On the other hand, the gas whose water vapor content is reduced is heated to a high temperature by the gas heater 43 when flowing through the return pipe 41, and then sprayed to the garbage A in the treatment tank 11 by the nozzle 44. By directly injecting the gas having a low relative humidity by being heated by the gas heater 43 directly to the garbage A, evaporation of moisture contained in the garbage A is promoted, and dew condensation in the return pipe 41 is achieved. Is also prevented. Moreover, since the inside of the heating chamber 13 has a negative pressure, the boiling point is lowered, it is possible to evaporate water at a low temperature, and it is possible to make it difficult for odorous components to leak out from the gap with the lid 13a.
[0021]
The water that flows down from the condensing unit 20 accumulates in the tank 31, but since the water in the tank 31 exceeds the water level d flows to the sewer pipe 1 through the drain pipe 33, the water level does not continue to increase. Stabilize. And most of the odorous components generated from the garbage A are dissolved in the water accumulated in the tank 31 and drained to the sewer pipe 1. In addition, since the water level difference between the condensed water discharge pipe 32 and the tank 31 is determined by the pressure difference between the sealed space and the sewage pipe 1, the condensed water is used when the pressure in the sealed space is a negative pressure value. The water level in the discharge pipe 32 or the condensing unit 20 is stabilized at a water level C higher than the water level in the tank 31. As the water level C becomes higher than the water level L which is the lower end of the both-end opening partition wall 24 as shown in FIG. 1, a flow path for guiding gas in a meandering manner is formed.
[0022]
On the other hand, if the pressure in the sealed space continues to decrease, the water level difference between the water in the condensing unit 20 and the water in the tank 31 increases. And if the water of the condensation part 20 becomes higher than the water level H which becomes the lower end of the lower end opening partition wall 23, the gas flow path will be interrupted, but when the water in the tank 31 decreases and falls to the water level e, it is shown in FIG. Thus, the air on the tank 31 side is sucked to the condensed water discharge pipe 32 side, and the pressure in the sealed space is prevented from being excessively reduced. Therefore, it is possible to prevent the water level of the condensing unit 20 from rising too much.
[0023]
As described above, according to the soot processor of the present embodiment, the condensing unit 20 is installed so that the plates 21 and 22 are vertical, so that the outside air can easily flow upward along the outer surface by the draft force. Further, by introducing the gas in a meandering manner, the water vapor contained in the gas can be easily brought into contact with the inner surfaces of the plates 21 and 22 to increase the cooling efficiency, and the two metal plates 21 and 22 are overlapped. Since it has a simple structure, it can be realized at low cost. In addition, meandering up and down and providing a communication space at the bottom can prevent the flow path from being blocked by water condensed in the flow path, and by blocking the communication space with accumulated water The gas can meander and flow without being communicated. Furthermore, when the pressure in the sealed space decreases and the water in the tank 31 falls to the water level e, the water level in the condensing unit 20 rises due to the configuration in which the air on the tank 31 side is sucked into the condensed water discharge pipe 32 side. It is possible to prevent the gas flow path from being blocked by being too much. In addition, a return pipe 41 for sending the gas cooled in the condensing unit 20 back to the heating chamber 13 is provided, and the gas in the sealed space is forcibly circulated by the fan 42 so that the gas containing a large amount of water vapor is condensed in the condensing unit 20. Since the gas which has been smoothly cooled and cooled in the condensing unit 20 and has a reduced water vapor content flows smoothly into the heating chamber 13, the evaporation of water contained in the garbage A and the condensation of the generated water vapor can be efficiently performed. This can be done and the drying performance can be increased. Furthermore, by heating the gas sent to the heating chamber 13 via the return pipe 41, the gas having a low relative humidity can be directly injected onto the garbage A to promote the evaporation of moisture, and the return pipe 41 can prevent water vapor from condensing. In addition, the structure in which the flow of gas from the condensing unit 20 to the sewer pipe 1 is blocked by the water accumulated in the tank 31 includes the heating chamber 13 and the condensing unit 20 without using an on-off valve such as an electromagnetic valve. Since the space can be sealed with respect to the outside, it can be constructed at low cost, and since the water in the tank 31 exceeds the water level d flows into the sewer pipe 1 through the drain pipe 33, the sealed space is maintained. It can be drained while.
[0024]
Moreover, since the water vapor | steam generated from the heated garbage A is condensed and drained with an odor, since an odor leak and a humidity rise can be prevented, deterioration of the indoor environment can be prevented. Furthermore, since the inside of the heating chamber 13 has a negative pressure, odor leakage from the gap with the lid 13a can be prevented, so that it is not necessary to increase the sealing performance excessively, and the boiling point is lowered and drying is performed at a low temperature. Since it can process, the energy required for a heating can be reduced and power consumption can be reduced, and the temperature rise in a room | chamber can be reduced. In addition, it is not necessary to provide an expensive device such as a vacuum pump in order to make the inside of the heating chamber 13 have a negative pressure, and it is not necessary to provide a deodorizing device, a water vapor discharging device, etc., so that the structure is simplified and the cost is reduced. be able to.
[0025]
In this embodiment, the fan 42 and the gas heater 43 are operated after a lapse of a predetermined time since the heating by the processing tank heater 12 was started. However, the present invention is not limited to this. The temperature, humidity, pressure, etc. in the heating chamber 13 or the water level in the shut-off drain part 30 may be detected and operated based on the detected value, or may be operated simultaneously with the treatment tank heater 12.
Further, the cutoff drainage part is not limited to the structure as in the present embodiment. For example, as shown in FIG. It is good also as the S-shaped pipe | tube 51 which forms the going up flow path 53 and the drainage flow path 54 which communicates from the up flow path 53 to the down sewer 1 again. Moreover, it is good also as a structure which interrupts | blocks a flow path not only using the structure interrupted | blocked with water but using on-off valves, such as a solenoid valve.
Further, the garbage A is not limited to the configuration heated by the processing tank heater 12, and may be configured to be heated by, for example, a gas burner or a microwave.
Further, in this embodiment, the gas flowing through the return pipe 41 is heated by the gas heater 43, but it may be configured not to be heated. Moreover, the structure which evaporates the water | moisture content contained in the garbage A with the hot air heated with the gas heater 43 without using the heater 12 for process tanks may be sufficient. Moreover, the structure which does not send gas back from the condensation part 20 to the heating chamber 13 may be sufficient.
Further, for example, as shown in FIG. 6, the water in the condensing unit 20 may flow into the tank 31 by an amount exceeding a predetermined water level higher than the water level L that is the lower end of the both-end opening partition wall 24. According to such a configuration, the gas can be constantly meandered and flowed by preventing the gas flow path from communicating with the lower part regardless of the pressure of the condensing unit 20 and the amount of water in the tank 31.
Further, in the present embodiment, the space including the heating chamber 13 and the fin tube 21 is sealed and negative pressure is set, but a configuration without negative pressure may be used, or a configuration without sealing may be used.
[0026]
Although the embodiments of the present invention have been described above, the present invention is not limited to these embodiments, and it is needless to say that the present invention can be implemented in various modes without departing from the gist of the present invention.
