The specific meanings of the above terms in the present invention can be understood in specific cases to those skilled in the art.

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood, however, that the description herein of specific embodiments is only intended to illustrate the invention and not to limit the scope of the invention. Moreover, in the following description, descriptions of well-known structures and techniques are omitted so as to not unnecessarily obscure the concepts of the present invention.

After the kitchen waste is put into the kitchen waste treatment composting device, the kitchen waste passes through a crushing unit, an enzyme decomposition unit, a salt removing unit and a centrifugal separation unit, the kitchen waste treatment composting device comprises a sterilization unit, a storage unit and a waste recycling unit, wherein the sterilization unit is used for converting (putting → crushing → microbial stirring → micro discharging (filtering) → discharging (water solubility) → residual food → secondary water treatment → salt removal first round → microbial re-stirring → drying (far infrared ray) → salt removal second round → natural organic compost generation) and then reaching the storage unit to form the organic compost.

Referring to fig. 1, as shown in the drawings, a composting apparatus (100) for kitchen waste treatment according to an embodiment of the present invention may include a main body casing (110).

The main body casing (110) has an internal space in the shape of a hollow box and can accommodate various components described below.

On one hand, a feeding opening (111) for feeding kitchen waste can be formed at the lower edge of one side of the main body protective shell (110). A delivery part (115) for delivering the kitchen waste to the upper part of the main body protective shell (110) can be arranged at one side of the feeding opening (111) for supplying the kitchen waste to the upper feeding opening (111).

Here, the transfer location (115) may be a conveyor belt. On the conveyor belt, a plurality of transfer plates may be formed at intervals along the conveyor belt to transfer the kitchen waste to the upper portion. In the transfer portion (115), a fork (in which a plurality of needle-like fork blades are arranged at regular intervals) may be provided in order to filter out foreign matter such as plastic bags. And filtering impurities when the kitchen waste passes through the fork.

In addition, a motor for driving each component and a driving part (117) for installing a driving component can be arranged in the opposite direction of the transferring part (115) for arranging the main body protective shell (110).

At this time, in the main body protective case (110), an opening and closing structure may be employed at a place where the transfer portion (115) is disposed, a place where the driving portion (117) is disposed, and a center where the driving portion (117) and the transfer portion (115) are disposed, so as to maintain each of the respective constituent elements.

An emergency release opening (113) may be provided in the main body casing (110). When a fault occurs, the kitchen waste directly passes through the upper part of the main body protective shell (110) without passing through the transferring part (115) and is directly thrown from the emergency throwing opening (113).

Here, an emergency release port 113 may be provided at a position corresponding to the enzyme decomposition unit 130. When the operation of the crushing unit (120) breaks down, the kitchen waste is directly put into the enzyme decomposition unit (130) through the emergency putting-in port (113) without passing through the crushing unit (120).

Of course, the enzyme decomposition unit (130) may be supplemented with a decomposition enzyme through the emergency inlet (113).

Also, a plurality of moving wheels 119 may be installed on the bottom surface of the main body cover 110 to be easily moved.

As shown in fig. 1, a kitchen waste treatment composting device (100) according to an embodiment of the present invention may include a crushing unit (120).

The kitchen waste supplied through the transfer portion 115 can be crushed by the crushing unit 120.

On the one hand, the crushing unit (120) may include a crushing roller (121) and a crushing roller (123). Crushing roller (121) can broken great kitchen garbage be less size, and crushing roller (123) can be smashed into littleer size to broken kitchen garbage in crushing roller (121).

On the other hand, the crushing roller (121) may be configured to rotate in a pair of opposite directions. Kitchen waste can be thrown between a pair of crushing rollers (121) which rotate oppositely to crush the kitchen waste. The outer peripheral surface of the crushing roller (121) can be provided with a plurality of cutting knives at certain intervals. The cutting blades of the pair of crushing rollers (121) are inserted between the spaces, and the kitchen waste can be crushed by mutual rotation.

The crushing roller (123) is located below the crushing roller (121). A pair of crushing rollers (123) which rotate oppositely are formed like the crushing roller (121) and can crush the entered kitchen waste.

At this time, the outer surface of the grinding roller (123) can be formed into an uneven grinding mode capable of grinding the kitchen waste into a particle shape.

On the other hand, the crushing roller (121) and the crushing roller (123) can be rotated together by a single crushing motor (127) through a power transmitting material such as a gear, a chain, or a belt. A grinding motor (127) for driving the grinding roller (121) and the grinding roller (123) is mounted in a driving part (117) of the main body protective shell (110). Receives the power transmitted by the power transmission material and rotates the power transmission material.

Here, since the kitchen garbage is once crushed into a small size in the crushing roller 121 and the crushed particles are secondarily crushed into smaller particles in the crushing roller 123, not only the load applied to the crushing motor 127 is reduced, but also the kitchen garbage having a high hardness in vegetables such as bones of meat, fish bones and shellfish, shells of nuts, inner cores of fruits, garlic stems and corn cobs can be easily crushed.

Also, the pulverizing unit (120) may include a screw feeder (125).

The spiral throwing and conveying device (125) can convey the smashed kitchen waste. The kitchen waste is crushed by the crushing roller 121 and the crushing roller 123 of the crushing unit 120, and then the kitchen waste is transferred and supplied to the center of an enzymatic decomposition unit 130 (described below).

As shown in fig. 1, a composting apparatus (100) for kitchen garbage treatment according to an embodiment of the present invention may include an enzyme decomposition unit (130).

In order to make the kitchen waste after the crushing process in the crushing unit (120) into sludge with smaller particle shape, the kitchen waste can be decomposed by the action of the decomposing enzyme in the enzyme decomposing unit (130).

In one aspect, the degrading enzyme introduced into the enzymatic degradation unit (130) may include lipase, protease, or a mixture thereof.

Here, the lipase can decompose fat, and the protease can decompose protein. The degrading enzyme can be various known degrading enzymes capable of degrading the kitchen waste.

At this time, in the enzyme decomposition unit (130), the kitchen waste is decomposed by the decomposing enzyme, thereby reducing the generation of the offensive odor.

The enzyme may be impregnated into the elastic porous carrier (135), and may be introduced into the enzymatic decomposition unit (130) together with the carrier (135) and supplied into the kitchen waste. If the carrier (135) is not used, the amount of the degradation enzyme lost may be too large, and the processing cost may be increased due to the excessive supply of the degradation enzyme.

In one aspect, the enzymatic decomposition unit (130) may include a stirring blade (131) and a screen (133).

A plurality of stirring blades (131) may be installed centering on the lateral axis. The decomposition enzyme and the kitchen waste supplied to the enzyme decomposition unit (130) can be stirred by the rotation of the stirring blade (131). The screen (133) is disposed at a lower portion of the agitating blade (131), and a mesh size of the screen (133) may be a predetermined size. Only the sludge decomposed into small-diameter sludge by the action of the decomposing enzyme is supplied to the salt removing sub-unit (140) described below through the screen (133).

The stirring motor (137) for driving the stirring blade (131) to rotate may be located in the driving portion (117) of the main body casing (110). The rotation of the stirring blade (131) is driven by directly transmitting power or indirectly transmitting power through a power transmission material.

As shown in fig. 1 and 2, a composting apparatus (100) for kitchen garbage disposal according to an embodiment of the present invention may include a salt removing unit (140).

In the enzyme decomposition unit (130), sludge is generated after the kitchen waste is decomposed. In the salt removing unit (140), a method of dissolving salt contained in the sludge with water to remove the salt can be used.

Here, the kitchen waste has high salinity, and if the kitchen waste is directly used as compost, the salinity may wither the plants. In order to reduce the salinity, the salinity is removed by a method of dissolving the salinity contained in the sludge in the salinity removing unit (140).

In one aspect, in the salt removal sub-unit (140), a dechlorination water tank (141) may be included. Water is supplied to the dechlorination water tank (141) to dissolve salt.

In the salt removing unit (140), sludge is prevented from settling on the bottom surface by air bubbles described below. Thus, the efficiency of removing salt can be improved.

The bubbles will be described in more detail below when the centrifugal separation unit (150) is described.

The dechlorination water tank (141) may be provided with a water tank discharge port for discharging the stored water to the outside. Microorganisms used in the sewage treatment apparatus are put into the dechlorination water tank (141). Thus, environmental pollution is reduced as much as possible.

As shown in fig. 2 and 3, the composting device (100) for kitchen waste treatment according to the embodiment of the invention may include a centrifugal separation unit (150).

The centrifugal separation unit (150) may be located at a side of the salt removing sub-unit (140). And separating water from the sludge after obtaining the sludge from which salt has been removed from the salt removing unit (140).

In one aspect, the centrifugal separation unit (150) may include a centrifuge material (152), a centrifuge shield (154), a return line (158), a booster shield (155), a booster impeller (156), and a speed control valve (159).

The centrifugal material (152) may be configured to be rotated by entering a mixture of water and sludge from the salt removing unit (140), and to be discharged after separating water and sludge by centrifugal force caused by the rotation.

The structure of the embodiment may be: a spiral centrifugal screw (153) is formed on the outer periphery of the centrifugal material (152), and a mixture of water and sludge is poured into the inside of the circular mandrel and then thrown outward by the action of centrifugal force.

At this time, the salt removing unit 140 may be connected to a portion of the centrifugal material 152 of the water and sludge mixture, and an inflow port 151 through which the water and sludge mixture flows from the salt removing unit 140 may be formed.

In a portion of the centrifugal screw 153 to which the centrifugal material 152 is connected, a drain flow hole may be formed. The centrifugal screw (153) may have a shape with a diameter that decreases as the distance from the sludge discharge direction increases.

The centrifugal material 152 may be inserted through the center of the centrifugal cover 154. In the water containing sludge supplied to the center of the centrifugal material 152 and discharged by centrifugal force, the sludge is gathered to the inner circumference of the centrifugal cover 154 due to the difference of specific gravity, and the water separated from the sludge can flow out from between the sludge and the centrifugal material 152 in close contact.

At this time, a sludge discharge port (154a) for discharging sludge may be formed at one end of the centrifugal cover (154). A water discharge port (154b) for discharging water separated from sludge can be formed at the other end of the centrifugal cover (154).

The centrifugal cover (154) may have a shape with a narrower diameter as the sludge discharge port (154a) is closer, as in the case of the centrifugal screw (153). In a portion where the sludge discharge port (154a) is provided, a portion where the diameter of the centrifugal screw (153) is narrowed may be arranged.

In addition, a pressurizing cover (155) for accommodating the water discharged from the water discharge port (154b) can be mounted on the centrifugal cover (154) at the end part where the water discharge port (154b) is formed. The inner side of the pressurizing cover (155) is connected with the centrifugal material (152), and can be installed on the pressurizing impeller (156) connected with the centrifugal material (152).

The booster impeller (156) can raise the water pressure of the water (which rotates together with the centrifugal material (152) and is ejected from the water ejection port (154 b)). The pressurizing cover (155) can form a pressurizing discharge port (for spraying water after the water pressure is raised by the pressurizing impeller (156)).

A return pipe 158 for supplying pressurized water to the dechlorination water tank 141 may be connected to the pressurized discharge port.

Here, the end of the return pipe (158) of the dechlorination water tank (141) may be lower than the water level of the dechlorination water tank (141). I.e. may be located in water.

Also, in the pressurizing cover (155), an air pipe (157) for inflow of air may be installed to inject air into the pressurized water, thereby generating bubbles in the dechlorination water tank (141). As the booster impeller (156) rotates, pressure is generated. By this pressure, the water discharged from the water discharge port 154b and the air in the air pipe 157 can be mixed into the inside of the pressurizing cover 155.

Also, in the return pipe (158), a speed control valve (159) that regulates the water pressure may be installed. A part of the pressurized and discharged water is supplied to a dechlorination water tank 141 through a speed control valve 159, and the remaining part of the water is supplied to a freely movable body 160 (described below). At the same time, the water pressure supplied to the dechlorination water tank 141 or the free moving body 160 is also adjusted.

Here, the speed valve (159) may be a three-port valve. The speed control valve (159) can adjust the water pressure supplied to the dechlorination water tank (141) and the free moving body (160) in a manner of adjusting the amount of water supplied to the dechlorination water tank (141) and the free moving body (160).

In one aspect, the centrifuge material (152) may be mounted in a rotatable manner (by the drive of a centrifuge motor mounted in the drive station (117)). The centrifugal motor directly transmits power or indirectly transmits power to the centrifugal material (152) through the power transmission material, so that the centrifugal material (152) can be rotated.

The centrifugal separation unit (150) is configured to supply a mixture of water and sludge to an inlet (151) of a centrifugal material (152) connected to a dechlorination tank (141) when the centrifugal motor rotates the centrifugal material (152). By the centrifugal force generated by the centrifugal material (152), a mixture of water and sludge is ejected into the inner circumference of the centrifugal cover (154).

The sludge having a high specific gravity is closely attached to the inner periphery of the centrifugal cover (154) and is located between the centrifugal material (152) and the sludge. The centrifugal screw 153 rotates together with the rotation of the centrifugal material 152, and the sludge closely adhered to the inner periphery of the centrifugal cover 154 is transferred to the sludge discharge port.

At this time, since the diameter of the inner periphery of the centrifugal cover (154) is smaller toward the sludge discharge port, water contained in the sludge can be wrung out so that water is squeezed out of the sludge while the sludge is pressurized.

On the other hand, water located between the sludge and the centrifugal material (152) is blocked by the sludge transferred along the centrifugal screw (153), and therefore, the water is not discharged in the direction of the sludge discharge port (154a), but flows out from the water discharge port (154b) located in the opposite direction.

The water discharged from the water discharge port 154b is pressurized by a pressurizing impeller 156 attached to a pressurizing cover 155, and then supplied to a return pipe 158 through the pressurizing water discharge port.

Here, in order to inject air into the water discharged from the water discharge port (154b) of the booster cap (155), the air is sucked through the air pipe (157), and then the air-mixed water is discharged through the booster discharge port.

On the other hand, the water ejected from the pressurized ejection port is supplied again to the dechlorination water tank 141 through the return pipe 158. A speed control valve (159) is installed in the return pipe (158), a part of water is supplied to the dechlorination water tank (141), and the rest of water is supplied to the free moving body (160).

In this way, the water supplied to the dechlorination water tank 141 through the return pipe 158 is injected with air through the air pipe 157, and when the air is sprayed into the water, bubbles are generated, thereby promoting the sludge to float in the water without depositing on the bottom surface of the dechlorination water tank 141. Thereby, the contact area of mud and water has been increased, the salinity effect can effectively be promoted and get rid of.

Here, a dechlorination filter 159a for removing salts from the water may be installed in the return pipe 158 to reduce the salinity of the feed water resupplied to the dechlorination water tank 141. The dechlorination filter (159a) may be a membrane filter. When a membrane filter is used, about 95% of the salt can be removed.

Although the embodiment is described as a spiral shape in which the centrifugal screw 153 is installed in the centrifugal material 152 in the centrifugal separation unit 150, it may be configured that a cylindrical mesh for filtering sludge is installed in the centrifugal material 152.

As shown in fig. 2, 4 and 5, the centrifugal separation unit (150) may further include a freely movable body (160) and a movable body connection hose (169).

The free moving body (160) obtains a part of water to be supplied to the dechlorination water tank (141) through a speed control valve (159) installed in the return pipe (158). Therefore, the sludge can freely move on the bottom surface of the dechlorination water tank (141), and the sludge settled on the bottom surface of the dechlorination water tank (141) is promoted to float.

If sludge is deposited on the bottom surface of the dechlorination water tank (141), the sludge is easily putrefied by the influence of water, and foul odor and contamination caused by bacterial growth are easily generated. Therefore, it is preferable to cause the sludge to float and to rapidly supply the sludge to the centrifugal separation unit (150).

On the other hand, the freely moving body (160) can freely move on the bottom surface of the dechlorination water tank (141) by means of water spraying. The speed control valve (159) and the freely moving body (160) are connected by a flexible bending moving body connecting hose (169). Thereby supplying water to the freely movable body (160) to urge the freely movable body (160) to move freely.

The freely moving body (160) is made of a material having a specific gravity higher than that of water, and sinks under the water so as to be freely moved on the bottom surface of the dechlorination water tank (141). The freely moving body (160) may include a water supply portion (161) and a moving body (163).

The water supply portion 161 is connected to a moving body connection hose 169 to obtain water supply. The shape of the moving body 163 may be a disk shape having an outer circumferential length longer than that of the water supply portion 161.

Also, the moving body (163) may be rotatably installed in the water supply portion (161). On the bottom surface of the moving body (163), a friction-reducing jet port (165) may be formed [ jetting a part of water obtained from the water supply portion (161) ]. On the outer periphery of the moving body (163), a movement jet port (167) may be formed [ jetting the remaining part of the water obtained from the water supply portion (161) in the side direction of the moving body (163) ].

At this time, since the motion jet port (167) is formed obliquely in a side direction of the outer circumference of the moving body (163), the moving body (163) is rotated by water jetted therefrom.

When the water supplied from the speed control valve 159 is supplied to the water supply portion 161 through the moving body connection hose 169, the free moving body 160 is constructed such that a part of the supplied water is jetted through the reduced friction jet port 165 to cause the moving body 163 to float finely on the bottom surface of the dechlorination water tank. The remaining water supplied to the water supply portion 161 is sprayed to the outer periphery of the freely movable body 160 through the movement jet port 167.

Thus, when water is sprayed through the moving spray port (167), the moving body (163) in the water supply portion (161) is rotated. The freely movable body (160) can move freely on the bottom of the dechlorination water tank (141) by the centrifugal force of the rotary motion body (163) and the water pressure of the unevenly sprayed water through the motion spraying opening (167). Thereby, the foreign matters deposited on the bottom surface of the dechlorination water tank (141) are promoted to float.

At this time, since the water supplied to the freely movable body (160) in the speed control valve (159) contains air, bubbles are generated in the ejected water through the movement ejection port (167) and the friction reducing ejection port (165) of the freely movable body (160), thereby effectively improving the floating effect of the sludge.

On the one hand, the moving speed of the freely moving body (160) can be adjusted by adjusting the pressure of water supplied to the freely moving body (160) in the speed control valve (159) and by discharging the pressure of water from the freely moving body (160).

As shown in fig. 1, a composting device (100) for kitchen waste treatment according to an embodiment of the present invention may include a sterilization unit (170).

The sterilization unit (170) is located below the centrifugal separation unit (150), and can perform sterilization work by heating sludge after the sludge separated from water is taken out through a sludge discharge port (154a) in the centrifugal separation unit (150).

In one aspect, the sterilization unit (170) may include a sterilization blade (171) and a hot air device (173).

The sterilized sludge can be heated by blowing hot air into the sterilization unit (170) by the hot air device (173).

The hot air supply device (173) may include a heater heated by electricity or gas, and a blower for generating air flow, and the air blown from the blower is heated by the heater to generate hot air.

On the other hand, hot air may be blown into the sludge in order to uniformly mix the hot air with the sludge (by supplying the sterilization unit (170) by rotating the sterilization blade (171)). At this time, the sterilizing blade (171) can be rotated by driving the sterilizing motor.

Here, in the sterilizing blade (171) and the blade shaft on which the sterilizing blade (171) is mounted, a hot air passage for supplying hot air is formed; the blade shaft and the sterilizing blade (171) are formed with hot air holes for injecting hot air. The hot air is supplied to the deep part of the sludge in a form of jetting the hot air through the hot air holes, thereby improving the sterilization effect.

On the other hand, on the upper side of the sterilization unit (170), a compost discharge port (for discharging compost produced by drying sludge toward the storage unit (180) located on the side of the sterilization unit (170)) may be formed.

As shown in fig. 1, a composting apparatus (100) for kitchen garbage disposal according to an embodiment of the present invention may include a storage unit (180).

The storage unit (180) can store compost produced in the sterilization unit (170).

In one aspect, the storage unit (180) may be positioned laterally of the sterilization unit (170) to receive and store compost discharged from a compost discharge port in the sterilization unit (170). The storage unit (180) may have a container shape with an open upper portion so as to easily insert, extract and carry compost from the main body housing (110).

As shown in fig. 1, the kitchen waste treatment composting device (100) according to the embodiment of the invention may include a controller (190) and an IOT communication module (191).

The controller (190) can control all the components of the transfer part (115), the crushing unit (120), the centrifugal separation unit (150), the enzyme decomposition unit (130), the salt removing unit (140), the centrifugal separation unit (150), the sterilization unit (170) and the like.

For example, the controller (190) can individually control the transfer speed of the transfer portion (115), the pulverizing speed of the pulverizing unit (120), the rotational speed of the stirring blade (131) in the enzyme decomposition unit (130), the rotational speed of the centrifugal material (152) in the centrifugal separation unit (150), the water pressure adjustment of the speed control valve (159), the temperature of the hot air device (173), the rotational speed of the sterilizing blade (171), and the like.

Also, the controller (190) can not only control the respective constituent factors but also monitor the operation state. Because the controller (190) comprises the IOT communication module (191), the control signals and the monitored information can be sent to the peripheral equipment or the control signals can be received from the peripheral equipment through the IOT, and therefore all the component factors can be effectively controlled.

In this case, the peripheral device may be a personal terminal or an integrated management server that manages and controls integrated management of a manager for the kitchen waste treatment composting apparatus (100).

Next, the action and effect between the respective compositions are explained;

according to the composting device (100) for treating the kitchen waste, the kitchen waste is fed through the feeding opening (111) of the main body protective shell (110) and then is supplied to the crushing unit (120) positioned at the upper part of the main body protective shell (110) through the conveying part (115).

On the other hand, the kitchen waste supplied to the crushing unit (120) through the transfer part (115) is crushed once by the crushing roller (121). Then, the mixture is secondarily pulverized into a small particle form by a pulverizing roller (123). The crushed kitchen waste is provided to an enzyme decomposition unit (130) through a spiral throwing conveyor (125).

The kitchen waste supplied to the enzymatic decomposition unit (130) is mixed with the decomposition enzyme impregnated in the carrier (135) by the stirring of the stirring blade (131), and is decomposed by the reaction of the decomposition enzyme. The sludge decomposed into particles having a size that can pass through the screen (133) of the enzymatic decomposition unit (130) is then put into a dechlorination water tank (141) in a salt removal unit (140) located below the enzymatic decomposition unit (130) through the screen (133).

At this time, the kitchen waste is decomposed into sludge by the action of the decomposing enzyme in the enzyme decomposing unit (130). Thereby, the generation of malodor is effectively reduced.

On the other hand, the sludge charged into the dechlorination tank 141 is dissolved in water to remove salts, and then flows into the centrifugal separation unit 150 located on the side of the dechlorination tank 141 together with the water.

Sludge contained in water flowing into the centrifugal separation unit (150) moves to the center of the centrifugal material (152) and is thrown from the center to the outer periphery by the centrifugal material (152) located on the outer periphery of the rotating centrifugal material (152). The sludge having a relatively high specific gravity is closely attached to the inner peripheral surface of a centrifugal cover (154) for containing the centrifugal material (152). The material (152) is centrifuged and the sludge is left behind as water from which the sludge is separated.

The sludge tightly adhered to the inner periphery of the centrifugal cover (154) is moved to a direction of a sludge discharge port (154a) by a centrifugal screw (153) formed in a spiral shape on the outer periphery of the centrifugal material (152). The water that is blocked by the sludge and is not allowed to flow in the direction of the sludge discharge port 154a passes through the flow hole of the centrifugal screw 153 and flows into the water discharge port 154b located in the opposite direction of the sludge discharge port 154 a.

On the other hand, the water discharged from the water discharge port (154b) is supplied to the pressure-increasing cover (155). The water supplied to the pressurizing cover (155) is ejected from the pressurizing outlet after the water pressure is increased by the rotation of the pressurizing impeller (156) installed in the pressurizing cover (155).

At this time, air is injected into the water through an air pipe (157) into which outside air flows in a portion of the supercharging cap (155) forming the water discharge port (154b) of relatively low pressure, and the air is discharged from the supercharging discharge port by the rotational force of the supercharging impeller (156).

The water sprayed to the pressurizing discharge port is supplied again to the dechlorination water tank 141 through a return pipe 158.

Here, air is injected into the water supplied to the dechlorination water tank 141, so that bubbles are generated in the dechlorination water tank 141,

so that the sludge floats. Thus, the contact between water and sludge is improved, and the salinity removing efficiency is improved.

At this time, a dechlorination filter 159a may be installed in the return pipe 158, and the water supplied to the dechlorination tank 141 may be supplied to the dechlorination tank 141 after removing salt content from the water.

A part of the water supplied to the return pipe (158) is supplied to the dechlorination water tank (141). The remaining part of the water is supplied to a moving body connection hose (169) through a speed control valve (159). The water supplied to the moving body connection hose 169 is supplied to the freely moving body 160 located on the bottom surface of the dechlorination water tank 141.

A part of the water supplied to the freely moving body (160) is sprayed to the bottom surface of the freely moving body (160) by the spray of the friction reducing spray port (165). Thus, the freely moving body (160) is floated from the bottom surface, and the freely moving body (160) is urged to move freely on the bottom surface of the dechlorination water tank (141).

The remaining water supplied to the freely movable body (160) is ejected by the movement of the ejection port (167). The water pressure formed by the injection of the moving injection port (167) causes the moving body (163) to rotate in the water supply portion (161) connecting the moving body connection hose (169) and the freely moving body (160). Because of the uneven drainage pressure, the moving body 163 encourages the sludge settled on the bottom surface to float while freely moving on the bottom surface of the dechlorination water tank 141.

At this time, when water is sprayed to urge the freely moving body (160) to freely move in the dechlorination water tank (141), bubbles are generated by air contained in the water, and therefore, an effect of urging the sludge to float by the bubbles is generated.

Further, when microorganisms used in a sewage treatment plant are added to the dechlorination tank 141 or the centrifugal separation unit 150 and wastewater is discharged to the outside, only the wastewater purified by the microorganisms is discharged, so that environmental pollution can be effectively reduced.

In one aspect, sludge separated from the drain water discharged from the sludge discharge port 154a of the centrifugal separation unit 150 is supplied to the sterilization unit 170 located at a lower portion. In the sterilization unit (170), hot air is supplied to a hot air device (173), and the sludge is heated and sterilized and dried in a mixed manner by the rotation of a sterilization blade (171) as the hot air and the sludge.

The dried sludge is discharged from a compost discharge port on the upper side of the sterilization unit (170) and stored in a storage unit (180) on the side of the sterilization unit (170).

After the compost is discharged to the storage unit (180), the user takes out the compost from the storage unit (180) and uses it as compost.

On the one hand, since the IOT communication module (191) is built in the controller (190), not only the operation state provided in the controller (190) can be monitored and managed through the peripheral devices, but also the respective constituent elements can be controlled.

Therefore, the kitchen waste treatment composting device (100) provided by the embodiment of the invention has the advantages that: because all the kitchen waste composting structural factors are arranged inside the main body protective shell (110), the kitchen waste composting structure is easy to install and convenient to move (carry).

Further, since the kitchen waste is subjected to the secondary pulverization treatment by the pulverizing roller (121) and the pulverizing roller (123), it is easy to subject various kitchen waste such as hard meat bones and shells of nuts to the pulverization treatment.

The water separated in the centrifugal separation unit (150) is returned to the dechlorination water tank (141). Thereby not discharging water containing salt to the outside and effectively preventing environmental pollution.

In the centrifugal separation unit (150), the pressure of the discharged water is raised by a booster impeller (156). Air is injected through an air pipe (157) to promote the dechlorination water tank (141) to generate bubbles. Through the bubble, when effectively preventing mud sediment, increased the contact of mud and water to the salinity efficiency has been got rid of in the promotion.

The water discharged from the centrifugal separation unit (150) allows a freely movable body (160) located on the bottom surface of the dechlorination tank (141) to move freely, thereby preventing sludge from accumulating on the bottom surface of the dechlorination tank (141). Therefore, the malodors and the increase and reproduction of bacteria can be effectively reduced, thereby reducing the environmental pollution to the maximum extent.

Further, since the driving portion 117 is located in one side surface of the main body casing 110, there is an advantage that maintenance is easy.

In addition, because the controller (190) comprises the I OT communication module (191), the I OT communication can be used for carrying out remote monitoring and control, and therefore the controller has the advantage of convenience in management.

Therefore, based on the innovative concepts of the present invention, the technical solutions of the present invention can be directly or indirectly applied to other related technical fields by making changes and modifications to the embodiments described herein, or by using equivalent structures or equivalent processes performed in the content of the present specification and the attached drawings, which are included in the scope of the present patent.
