Description

Technology Field

[0001] The present invention relates to a food waste treatment device with improved odor reduction and drying efficiency, and more specifically, to a food waste treatment device with improved odor reduction and drying efficiency that can condense water vapor generated during the drying process of food waste and discharge it to the outside, as well as circulate the odor discharged along with the condensate back into the interior of the main body to reduce the odor. Background Technology

[0003] Generally, food waste treatment devices recycle food waste discharged from apartments and multi-unit housing into compost by drying, fermenting, and maturing it.

[0004] Since these food waste treatment devices heat various types of food waste and maintain a temperature above a certain level to carry out drying or fermentation, steam (moisture) and odors are inevitably generated.

[0005] Furthermore, because food waste contains moisture, it decomposes easily and emits a severe odor, making it unsuitable for long-term storage. Additionally, the generation of leachate during the landfill process poses a serious problem, causing soil and water pollution.

[0006] In addition, wastewater sludge is collected collectively from wastewater-generating factories and wastewater treatment plants installed downstream of each river to prevent water pollution such as river pollution, but this has the problem of causing soil pollution as well as incurring significant costs for the landfill itself.

[0007] In particular, livestock manure is the most severe food waste causing water and soil pollution and foul odors; as the scale of the livestock industry has grown due to increased meat consumption, the volume of manure generated has increased, leading to practical limitations in composting treatment.

[0008] Furthermore, since steam and odors generated during the food waste drying process are released to the outside, it pollutes the surrounding environment and causes problems such as complaints from neighbors due to severe stench.

[0009] Meanwhile, water vapor generated during the drying process of food waste condenses at the top of the main body and falls back inside, causing a problem that reduces the drying and reduction efficiency of food waste. Prior art literature

Specific details for implementing the invention

[0030] The technical configuration for achieving the objectives of the present invention as described above will be explained in more detail with reference to the attached drawings as follows.

[0031] FIG. 1 is a perspective view showing the configuration of a food waste treatment device with improved odor reduction and drying efficiency according to the present invention, FIG. 2 is a front view showing the configuration of a food waste treatment device with improved odor reduction and drying efficiency according to the present invention, FIG. 3 and FIG. 4 are side views showing the configuration of a food waste treatment device with improved odor reduction and drying efficiency according to the present invention, FIG. 5 is a perspective view showing the configuration of a steam discharge unit in the present invention, and FIG. 6 and FIG. 7 are reference drawings showing the operating state of a food waste treatment device with improved odor reduction and drying efficiency according to the present invention.

[0032] The present invention comprises: a main body (110) formed to heat and dry food waste, having an input section (111) formed on one side of the upper portion for introducing food waste into the interior and an output section (112) formed on one side of the lower portion for discharging dried food waste to the outside; a stirring unit (120) formed to stir the food waste introduced into the interior of the main body (110); and a steam discharge unit (130) connected to the upper portion of the main body (110) to condense steam generated during the drying process of food waste and discharge it to the outside, and to allow the odor discharged along with the condensed water to circulate back inside.

[0033] In particular, the main body (110) is formed to be completely covered with a cover made of insulating material so as to prevent freezing and perform an insulating function during the winter season.

[0034] In addition, the main body (110) can maintain the temperature of food waste at a temperature required for composting treatment, such as fermentation and maturation, by circulating a heat transfer fluid at a certain temperature on its outer surface.

[0035] In addition, the above-mentioned input section (111) can be formed in the form of a combination of a pipe and a valve or a cover to allow food waste to be introduced into and blocked from entering the main body (110).

[0036] Meanwhile, the discharge section (112) can be formed in the form of a cover that opens and closes using a cylinder or motor power source so that food waste can be discharged to the outside after drying and composting inside the main body (110).

[0037] And it may include a plurality of measuring sensors for measuring humidity and temperature inside the main body (110); and a heating means for heating the interior of the main body (110) to a constant temperature.

[0038] Here, the measurement sensor may use a sensor of various shapes and specifications to check the internal temperature or humidity of the main body (110) that changes during the composting process of food waste.

[0039] In particular, the heating means may use a heater rod or a heating wire, etc.

[0040] Meanwhile, the lower part of the main body (110) may include a weight measuring unit for measuring the weight of food waste; thereby allowing the completion time of composting or the time of input of the waste to be determined.

[0041] In other words, by comparing the current weight of food waste measured by the weight measuring unit with a preset appropriate amount of food waste weight, it is possible to verify whether the food waste has been fermented and dried to complete composting.

[0042] Here, the weight measuring unit may use sensors having various configurations and specifications, such as load cells.

[0043] In addition, the front of the main body (110) may include a display unit for checking the weight and processing status of food waste.

[0044] Here, the above-mentioned display unit can perform input / output functions using a touch panel to display the current operating status of food waste composting or to allow an administrator to change setting values.

[0045] At this time, the touch panel can display icons with various functions depending on the situation, and can also execute the corresponding command when touched with a finger or a touch pen.

[0046] And the above stirring unit (120) performs the function of mixing food waste introduced into the inside of the main body (110) and inducing composting treatment through fermentation, drying, and maturation processes.

[0047] The above stirring unit (120) includes at least one stirring blade (121) formed to be positioned horizontally inside the main body (110) and capable of rotating; and a driving means (122) for rotating the stirring blade (121).

[0048] In particular, the stirring blade (121) can rotate smoothly on both sides of the main body (110) via bearings.

[0049] Here, the stirring blades (121) are arranged in a spiral shape to facilitate smooth stirring of food waste.

[0050] At this time, the stirring blade (121) can be formed to have various shapes and specifications.

[0051] In addition, the above driving means (122) may be used by combining a motor and a reduction gear having various forms and configurations, but in the present invention, a hydraulic motor and a hydraulic pump are used to effectively cope with the resistance and load generated during the process of stirring food waste.

[0052] In the present invention, the steam discharge unit (130) can maximize drying efficiency by condensing the steam generated during the drying and composting process of food waste and discharging it to the outside, thereby minimizing the moisture content of the food waste and shortening the drying time.

[0053] The above steam discharge unit (130) comprises: a body (131) formed to penetrate the upper part of the main body (110); a plurality of steam condensation sections (132) arranged inside the body (131) to allow steam to condense on the surface and flow down; a collection section (133) formed to collect the flowing condensate located below the plurality of steam condensation sections (132); a storage section (134) formed to store the condensate by connecting to both sides or one side of the plurality of collection sections (133); a drainage section (135) formed to drain the condensate by connecting to one side or both sides of the storage section (134); a condensate trap section (136) formed to store the condensate at a certain level inside by connecting to the drainage section (135); and a connection section (137) formed to connect the condensate trap section (136) and the body (131). It includes: an odor circulation section (138) formed to connect the drainage section (135) and the connection section (137) so that odors discharged through the drainage section (135) can pass through the connection section (137) and circulate back into the interior of the body (131); and a condensate discharge section (139) formed to be connected to one side of the condensate trap section (136) at a height lower than that of the odor circulation section (138) so as to discharge condensate to the outside.

[0054] In particular, the body (131) is formed to have various shapes and sizes so that it is connected to penetrate the upper part of the main body (110) and steam generated during the stirring and drying process of food waste can rise and collect.

[0055] Meanwhile, the above steam condensation unit (132) is formed so that steam can condense on the surface and flow down to the bottom.

[0056] At this time, the above steam condensation unit (132) is formed so that its width gradually decreases from the top to the bottom when viewed from the side, thereby allowing the condensed water to easily flow down in the downward direction and concentrate in one direction.

[0057] In addition, the above-mentioned water collection unit (133) performs the function of collecting condensate flowing down to the lower part of the above-mentioned water vapor condensation unit (132).

[0058] Here, the above-mentioned water collection section (133) is formed to be longer than the length of the above-mentioned water vapor condensation section (132) and has an open top so as to collect the condensate flowing down through the above-mentioned water vapor condensation section (132) inside.

[0059] At this time, the above-mentioned water collection section (133) can be formed to gradually tilt downward from one side to the other along the longitudinal direction, which can induce the condensed water to flow easily down to the other side and concentrate in the storage section (134).

[0060] And the storage unit (134) is connected to a plurality of the water collection units (133) to store condensate and guide it to move to the drainage unit (135).

[0061] In addition, the drainage portion (135) is formed to have a certain length and direction so as to drain condensate to the outside of the body (131).

[0062] In addition, the above condensate trap (136) is located at the bottom of the drainage section (135) and stores condensate at a certain level inside to block odors from passing through.

[0063] Here, the condensate trap (136) can be formed in a 'U' or 'S' shape to store condensate.

[0064] Meanwhile, the connecting part (137) connects the condensate trap part (136) and the body (131) to each other, thereby inducing the odor passing through the odor circulation part (138) to circulate back into the inside of the body (131).

[0065] In particular, the above odor circulation unit (138) allows condensate passing through the drainage unit (135) to move to the condensate trap unit (136) for storage, and since odors cannot pass through the condensate trap unit (136), these odors pass through the odor circulation unit (138) and the connection unit (137) to circulate inside the body (131), thereby minimizing external leakage.

[0066] In addition, the condensate discharge section (139) is positioned at a height lower than that of the odor circulation section (138) to determine the water level of condensate that can be stored inside the condensate trap section (136), and when the amount of condensate flowing in through the drainage section (135) increases, the condensate stored inside the condensate trap section (136) is naturally discharged to the outside.

[0067] The present invention includes a cooling water circulation unit (140) formed to circulate cooling water by connecting it to the steam condensation unit (132) of the steam discharge unit (130).

[0068] That is, the cooling water circulation unit (140) can improve the drying efficiency of food waste by lowering the surface temperature of the steam condensation unit (132) to create a temperature difference with the steam of the food waste, thereby maximizing the condensation phenomenon of the condensed water and discharging a large amount of condensed water to the outside through the steam discharge unit (130).

[0069] Here, the cooling water circulation unit (140) comprises: an inlet pipe (141) connected to one side of the steam condenser (132); a circulation pipe (142) connected to the other side of the steam condenser (132) and having a circulation pump (142a) on one side; and a heat exchanger (143) formed between the inlet pipe (141) and the circulation pipe (142).

[0070] In particular, the above-mentioned circulation pump (142a) can improve the amount of condensate generated by cooling the surface temperature of the above-mentioned steam condensation unit (132) by supplying the cooling water, which has had its temperature lowered by passing it through the above-mentioned circulation pipe (142) to the inside of the above-mentioned steam condensation unit (132) through the above-mentioned inlet pipe (141), after passing it through the above-mentioned heat exchanger (143).

[0071] In addition, the heat exchanger (143) can be formed with various specifications and configurations, such as a plate heat exchanger having a flow path on the inside.

[0072] Accordingly, as illustrated in FIG. 6, the present invention condenses steam generated during the process of heating and drying food waste onto the surface of a plurality of steam condensation units (132), flows down to the bottom, and is stored in the storage unit (134), and the stored condensate is drained through the drainage unit (135).

[0073] At this time, by operating the cooling water circulation unit (140), cooling water is circulated into the interior of the steam condensation unit (132) to cool the surface, thereby increasing the condensation generated on the surface of the steam condensation unit (132) due to the temperature difference with the steam, and thus improving the drying efficiency of food waste.

[0074] Next, as illustrated in FIG. 7, the condensate passing through the drainage section (135) is stored in the condensate trap section (136), and when it exceeds a certain level, it is discharged to the outside through the condensate discharge section (139).

[0075] At this time, the odor passing through the drainage section (135) along with the condensate cannot be discharged to the condensate discharge section (139) due to the condensate trap section (136), and can be reduced by passing through the connection section (137) via the odor circulation section (138) and circulating back into the interior of the body (131) to be discharged to the outside.

[0076] Although the embodiments of the present invention have been described in detail as above, the scope of the present invention is not limited thereto, and it is obvious that the scope of the present invention includes those that are substantially equivalent to the embodiments of the present invention.
