Description

Organic waste treatment system

[0001] The present invention relates to an organic waste treatment device.

[0002] With the recent improvement in living standards, meat consumption is increasing, and consequently, the amount of various organic waste other than food waste is rising day by day.

[0003] These organic wastes are collected separately from general household waste and disposed of through landfill or incineration. Direct landfilling is currently prohibited because it causes complaints due to foul odors and leads to soil and drinking water contamination from leachate.

[0004] Furthermore, the incineration of livestock carcasses causes air pollution, and in particular, highly toxic carcinogens such as dioxins are generated during the process, leading to strict regulations being implemented.

[0005] Accordingly, livestock carcass waste treatment devices that dry or ferment livestock carcasses using microorganisms have recently been proposed.

[0006] As background technology to the present invention, Korean Registered Patent No. 10-1873306 (Registration Date: June 26, 2018) “Organic waste treatment device using microorganisms” (hereinafter referred to as “prior art”) has been disclosed.

[0007] The conventional technology is equipped with a treatment tank into which organic waste is introduced, a rotating body that agitates the organic waste introduced into the treatment tank, and a heating unit installed on the outer wall of the treatment tank to heat the treatment tank to an appropriate temperature for activating microorganisms.

[0008] The present invention provides an organic waste treatment device capable of smoothly processing organic waste.

[0009] However, the technical problems that this embodiment aims to solve are not limited to the technical problems described above, and other technical problems may exist.

[0010] An organic waste treatment device according to one embodiment of the present invention comprises a reaction chamber having a space formed therein for treating organic waste, a stirring unit located inside the reaction chamber for crushing and stirring the introduced organic waste, a driving unit for rotating the stirring unit, and a heating unit for heating the organic waste located inside the reaction chamber. In this case, the stirring unit includes a stirring shaft located inside the reaction chamber and a stirring blade positioned at a predetermined distance along the longitudinal direction of the stirring shaft and coupled to be perpendicular to the stirring shaft, wherein the stirring blade is characterized by being spread apart from an adjacent stirring blade at a set angle.

[0011] According to one embodiment of the present invention, there is an effect of providing an organic waste treatment device capable of smoothly processing organic waste.

[0022] The following examples are detailed descriptions to aid in understanding the present invention and are not intended to limit the scope of the present invention. Accordingly, inventions within the same scope that perform the same function as the present invention will also fall within the scope of the present invention.

[0023] The present invention relates to an organic waste treatment device (10).

[0024] FIG. 1 is a schematic diagram of an organic waste treatment device according to one embodiment of the present invention, FIG. 2 is a partial cross-sectional view of an organic waste treatment device according to one embodiment of the present invention, and FIG. 3 is a partial cross-sectional view of an organic waste treatment device according to another embodiment of the present invention.

[0025] Hereinafter, an organic waste treatment device (10) according to one embodiment of the present invention will be described with reference to FIGS. 1 to 3.

[0026] The organic waste treatment device (10) includes a reaction chamber (100), a stirring unit (200), a driving unit (300), and a heating unit (400).

[0027] A reaction chamber (100) is formed with a space for processing organic waste inside. For example, in addition to organic waste such as food waste and animal carcasses, a mixing operation can be performed on a material in which a carrier composed of sawdust, rice husks, and bamboo and a microbial strain are introduced and mixed in the reaction chamber (100). At this time, crushing and mixing operations of the mixed material can be performed inside the reaction chamber (100) through a mixing unit (200).

[0028] A stirring unit (200) is located inside a reaction chamber (100) and crushes and stirs the introduced organic waste. Referring to FIG. 2, the stirring unit (200) may include a reaction tank (110) with a U-shaped cross-section and a roof (120) covering the top of the reaction tank (100).

[0029] As described above, the reaction tank (110) has a U-shaped cross-section, and depending on the processing capacity, two reaction tanks (110) may be arranged in parallel, and a stirring unit (200) may be installed in each reaction tank (110). A detailed explanation of this will be provided later.

[0030] The roof (120) is located on the upper part of the reaction tank (110) and can be extended upward from each upper part of the reaction tank at a predetermined angle. At this time, the angle of the roof (120) can be set in the range of 40 to 45 degrees. Due to this structure, oil vapor generated when processing organic waste inside the reaction tank (110) condenses upon contact with the roof (120), and the condensed water can flow down along the slope of the roof (120) and flow back into the interior of the reaction tank (110).

[0031] Additionally, referring to FIG. 2, the roof (120) is formed such that the left and right sides have a predetermined angle toward the downward direction, and the central part may be formed parallel to the ground. For example, an inlet for introducing organic waste may be formed on the left or right side of the roof (120), and a connecting pipe connected to a gas condenser, which will be described later, may be installed in the flat central part.

[0032] The heating unit (400) heats organic waste located inside the reaction chamber (100). For example, the heating unit (400) may be attached along the outer surface of the reaction vessel (110), preferably along the lower perimeter, and may heat the carrier to a temperature suitable for microbial growth. In this case, the heating unit (400) may be a device that heats through induction heating. For example, the heating unit (400) may be a high-frequency heater or an induction heater, but is not limited thereto.

[0033] The drive unit (300) rotates the stirring unit (200). For example, the drive unit (300) is a rotating motor and can rotate the stirring shaft (210) through a chain and gear, but is not limited thereto, and the motor may be directly connected to the stirring shaft (210) to transmit rotational force.

[0034] The stirring unit (200) includes a stirring shaft (210) and a stirring blade (220).

[0035] The stirring shaft (210) can be installed along the longitudinal direction inside the reaction chamber (100), that is, inside the reaction chamber (100). Additionally, the stirring shaft (210) can be supported in the reaction chamber (100) through a bearing member and connected to a driving unit (300) to receive rotational force and rotate in a clockwise or counterclockwise direction.

[0036] Referring to FIG. 2, the stirring blade (220) is positioned at a predetermined distance along the longitudinal direction of the stirring shaft (210) and is coupled perpendicular to the stirring shaft (210). Additionally, the stirring blade (220) spreads apart from adjacent stirring blades (220) at a set angle, and the set angle can be set as an equal angle. At this time, the equal angle can be 120 degrees. Through this, organic waste introduced into the interior of the reaction tank (110) can be smoothly crushed and stirred.

[0037] Referring to FIG. 3, the reaction tank (110) can form two spaces where organic waste is processed by continuously forming a U-shape. At this time, a stirring unit (200) can be located in each of the two spaces of the reaction tank (110). In other words, the reaction tank (110) can have twice the capacity compared to a single arrangement by continuously arranging U-shapes, and a stirring unit (200) can be placed in each area to process a larger amount of organic waste.

[0038] Additionally, when the reaction tank (110) is formed in a continuous U-shape and has two spaces, the central part is formed lower than the height of the side walls, and accordingly, organic waste can be moved to another space by the stirring unit (200), so that organic waste can be evenly introduced and stirred into the two spaces.

[0039] Hereinafter, a stirring blade (220) according to the first embodiment of the present invention will be described with reference to FIGS. 4 and FIGS. 5.

[0040] The stirring blade (220) may include a first blade (221) and a second blade (222).

[0041] The first blade (221) may be formed to extend in a direction parallel to a plane perpendicular to the stirring axis (210). For example, the first blade (221) may have a long rectangular shape extending from the stirring axis (210), and may be one of a parallelogram shape that narrows as it moves away from the stirring axis (210), a parallelogram shape that widens as it moves away from the stirring axis (210), or a long rectangular shape, but is not limited thereto.

[0042] The second blade (222) is formed to extend in both directions from the center of the width direction of the first blade (221) and can be formed to have a predetermined angle with respect to the first blade (221). In other words, the cross-sections of the first blade (221) and the second blade (222) can have an approximate cross shape.

[0043] Additionally, the second blade (222) may include a recess (222a) formed in a 'U' shape at the center of both sides. In other words, the second blade (222) may have a larger area at the part adjacent to the stirring shaft (210) and at the part far from the stirring shaft (210) than at the center. Accordingly, it is possible to effectively stir while minimizing the load on the drive unit (300).

[0044] Additionally, the second blade (222) may be formed such that the portion adjacent to the stirring shaft (210) has a greater width than the portion further from the stirring shaft (210). For example, the second blade (222) may have the same width from the portion contacting the stirring shaft (210) to the recess (222a), and the same width from the recess (222a) to the end, but the width of the portion adjacent to the stirring shaft may be greater.

[0045] These first blade (221) and second blade (222) can each perform different roles. For example, the first blade (221) functions to crush organic waste by applying pressure to its periphery as the stirring shaft (210) rotates, and the second blade (222) functions to move organic waste by applying pressure to its surface area.

[0046] Additionally, referring to FIG. 5, the second blade (222) is formed to have a predetermined angle (α) with respect to a plane perpendicular to the first blade (221), and the predetermined angle (α) may be 10 to 15 degrees.

[0047] In addition, the angle (α) of the second blade (222) is such that the corner facing the center of the stirring shaft (210) has a predetermined angle in the direction opposite to the rotation direction of the stirring shaft (210), and accordingly, organic waste can be moved to the central part of the reaction tank (110) by pressurizing the organic waste through the second blade (222). However, it is not limited to this, and the second blade (222) can be formed to have an angle opposite to that of the adjacent blade (222). For example, if the angle of the second blade (222) is 10 degrees in the direction of rotation, the angle of the adjacent blade (222) is formed to be 10 degrees in the opposite direction of rotation, so that the second blade (222) moves the organic waste in the direction where the adjacent blade (222) is located, and the adjacent blade (222) moves the organic waste in the direction where the second blade (222) is located, thereby having the effect of allowing for smoother stirring.

[0048] Referring again to FIG. 4, the stirring unit (200) may further include a paddle (223) located at the end of the stirring blade (220) and scraping the inner surface of the reaction vessel (110). The paddle (223) may be formed in a fan-shaped plate. Additionally, the paddle (223) may be formed in a plate shape, but both ends may be bent. In this case, the ends of the bent portions of the paddle (223) may contact or be adjacent to the inner surface of the reaction vessel (110), and as the stirring shaft (210) rotates, the paddle (223) may scrape the inner surface of the reaction vessel (110) to prevent the carrier from sticking to the inner surface.

[0049] Hereinafter, a stirring blade (220) according to a second embodiment of the present invention will be described with reference to FIGS. 6 and FIGS. 7.

[0050] The second blade (222) may further include a crushing section (222b) formed to protrude outwardly at both outer ends. For example, the crushing section (222b) may be formed with a width that decreases from the end of the second blade (222) to a predetermined length. At this time, the crushing section (222b) may serve to crush organic waste that moves along the longitudinal direction of the reaction chamber (100) as the stirring unit (200) rotates.

[0051] At this time, referring to FIG. 6, the second blade (222) among the plurality of second blades (222) adjacent to the front and rear walls of the reaction vessel (110) is characterized in that a crushing portion (222b) is not formed at the corner facing the front and rear walls of the reaction chamber (100). Among the second blades (222), the second blade (222) located on the front and rear walls is preferably in close contact with the front and rear walls as much as possible to prevent organic waste from adhering to the front and rear walls, and accordingly, a crushing portion (222b) may not be formed on the second blade (222) adjacent to the front and rear walls.

[0052] Referring to FIG. 7, the first blade (221) may include a plurality of blades (221b) that are formed to protrude in the left-right direction and are spaced apart by a predetermined distance in the longitudinal direction. The plurality of blades (221b) may be formed to protrude in the left-right direction from the outer side of the first blade (221), and accordingly, organic waste introduced can be effectively crushed as the first blade (221) rotates clockwise or counterclockwise. For example, each blade (221b) may have a fan shape, but is not limited thereto.

[0053] Additionally, the plurality of blades (221b) may be formed to protrude further away from the stirring axis (210). For example, the ends of the plurality of blades (221b) may be formed to be in contact with a line segment having a predetermined angle (β) with respect to the center of the stirring axis (210).

[0054] Hereinafter, with reference to FIG. 8, a stirring blade (220) according to the third embodiment of the present invention will be described.

[0055] The stirring blade (220) according to the third embodiment may have a parallelogram shape in which the width of the second blade (222) narrows as it moves away from the stirring axis (210). Accordingly, there is an effect of minimizing deformation of the second blade (222) by external force.

[0056] Additionally, among the plurality of second blades (222), the second blade (222) adjacent to the front and rear walls of the reaction vessel (110) may be formed parallel to the front and rear walls at the corner facing the front and rear walls of the reaction chamber (100). Among the second blades (222), the second blade (222) located on the front and rear walls is preferably in close contact with the front and rear walls as much as possible to prevent organic waste from adhering to the front and rear walls, and accordingly, the second blade (222) adjacent to the front and rear walls may be formed parallel to the front and rear walls.

[0057] Meanwhile, the organic waste treatment device (10) may further include a gas condenser that captures and condenses the gas generated in the reaction chamber (100). In other words, the steam generated during the process of treating organic waste can be discharged to the outside as clear water through the condenser.

[0058] The foregoing description of the present invention is for illustrative purposes only, and those skilled in the art will understand that other specific forms can be easily modified without altering the technical concept or essential features of the present invention. Therefore, the embodiments described above should be understood as illustrative in all respects and not restrictive. For example, each component described as a single unit may be implemented in a distributed manner, and components described as distributed may likewise be implemented in a combined form.

[0059] The scope of the present invention is defined by the claims set forth below rather than by the detailed description above, and all modifications or variations derived from the meaning and scope of the claims and the concept of equivalents thereof should be interpreted as being included within the scope of the present invention.
