Description

[0001] Apparatus for Disposing of Food Waste [0002]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a food waste disposal apparatus, and more particularly, to a food waste disposal apparatus capable of effectively separating solids and liquid components by treating food waste in stages.

In modern society, as the income increases and the life improvement leads to the abundant material life, the living garbage is also generated in proportion to this, and such household garbage has a serious influence on the environmental pollution.

In particular, food waste is mostly organic material, which is highly pernicious. Due to the nature of our dietary culture, large quantities of food waste are mixed with water and have a large number of food culture characteristics. Therefore, such food waste is a major source of environmental pollution, It is becoming a factor.

Food waste discharged from such homes and restaurants contains a large amount of water, so if it is left unattended for a long time, it becomes easy to decay, and a large amount of odor and wastewater are generated in the process of decaying the waste, And the atmosphere is seriously polluted when incinerated.

The first priority for the treatment of food waste is to remove dehydration, that is, the water contained in the food. In the case of food waste such as starch, since water is continuously absorbed, There is a problem that dehydration is not easy.

Food waste is 80-85% in water content, which is easily corroded to produce odor and sewage. It is difficult to separate and transport the waste. In the landfill process, a large amount of leachate flows out, causing secondary environmental pollution such as groundwater pollution, In the incineration process, additional use of the auxiliary fuel is required due to the lowering of the incineration temperature, so that incineration costs are increased and the secondary environment pollution is likewise caused.

As one of the methods to solve such problems, there is utilized a method of separating food waste by solid-liquid separation, using solid material as feed, compost, fuel, etc., and separating the water into dirty water or water treatment.

The solid-liquid separator currently in use is a type in which a screw is installed in a perforated network of a hole having a diameter of 2 mm. The food waste crushed by the screw is sucked into the perforated network and the pitch of the screw is gradually decreased, The solid particles with a small particle size escape out of the perforated network along with the moisture, and the solid particles with the remaining particles are pushed into the screw in the perforated mesh, and the solid solution is separated. Such a solid-liquid separator requires a large force for pressing with a screw, which has a problem that wear of the perforated network and the screw is very severe.

In addition, high energy costs due to the use of large capacity motors, short replacement cycle due to wear of perforated nets and screws, deterioration of processing ability due to clogging of dewatering holes, excessive drainage of solids due to the fact that dewatering holes can not be made below 2mm It has many problems such as marine pollution caused by the dumping of solid matter into the ocean.

On the other hand, in order to increase the efficiency of solid-liquid separation, solid waste may be separated by solid-liquid separation using a centrifugal separator such as Delcanta or a belt press or by sedimentation separation using a coagulant. However, And there is a problem that when a large amount of coagulant is used, a separated solid material causes a vicious circle which is another industrial waste.

In addition, the solid-liquid separation operation by the above-described devices takes a long time, and the efficiency of the treatment is deteriorated.

1, the apparatus for treating garbage according to an embodiment of the present invention includes a moving module 110, a crushing module 150, a dewatering module 190, and a leachate module 230. As shown in FIG.

The solid arrows in Fig. 1 indicate the movement of solids contained in the food waste, and the dashed arrows indicate the movement of the liquid component.

2, the moving module 110 includes a moving housing 112, a receiving portion 141, an absorbing unit 130, and a moving unit 121. [

In this embodiment, the moving housing 112 is formed with an inlet 114 through which food waste flows and an outlet 116 through which food waste is discharged.

The inside of the movable housing 112 can be partitioned into a solids moving space 111 and a liquid moving space 135 which are two spaces by the receiving part 141. The solids moving space 111 is a space in which solid matter contained in the food waste moves, and the liquid moving space 135 is a space in which liquid components contained in the food waste move.

The receiving portion 141 may be formed in a stepped shape having a plurality of steps. And may be formed so as to become lower toward the discharge port 116 side from the inlet 114 side. As a result, the food waste introduced from the inlet 114 can be gradually moved downward and discharged through the outlet 116.

The liquid transfer hole 143 may be formed in each step of the receiving part 141 so that the liquid component contained in the food waste may fall into the liquid moving space 135. [ The liquid moving space 135 is connected by the leachate module and the discharge pipe 118 so that the liquid component separated from the moving module 110 can be moved to the leachate module through the discharge pipe 118.

Here, the leachate module is a storage tank for storing the liquid component of the food waste.

As shown in FIG. 3, the absorption unit 130 may be placed in each step of the receiving unit 141 to absorb a part of the liquid component contained in the food waste, and may be moved to the liquid movement space 135. To this end, the absorption unit 130 of the present embodiment may include an absorption portion 137, a mesh portion 135, and a cover portion 131. [

The absorbing part 137 may be formed of a porous material to absorb the liquid component. Here, as the absorption part 137, a sponge or a porous foam may be applied. As a result, the liquid component absorbed by the absorption portion 137 can fall into the liquid movement space 135 through the liquid movement hole 143 due to its own weight.

The mesh portion 135 may be formed of a mesh having a plurality of small holes to surround the absorption portion 137 from the outside. The mesh portion 135 can allow only the liquid component to move to the absorption portion 137 by passing only the liquid component without passing the solids of the food waste. As a result, it is possible to prevent the liquid component from adhering to the surface of the absorbing portion 137 and interfering with the absorption of the liquid component.

The cover part 131 is provided so as to surround the mesh part 135 from the outside so that the liquid component absorbed by the absorption part 137 can be smoothly discharged through the liquid transfer hole 143. [ And to cover only the upper surface. Also, a plurality of through holes 133 through which the liquid component can pass may be formed in the cover part 131. The through hole 133 may be a hole of a size larger than the mesh of the mesh portion 135 and some solids may pass through the through hole 133. Solids passing through the through hole 133 may be filtered by the mesh portion 135.

Here, the absorbing portion 137, the mesh portion 135, and the cover portion 131 are all detachable, and the cover portion 131 can be detachably coupled to the mobile housing 112. That is, the absorbing unit 130 is detachably coupled to the moving housing 112, and the absorbing unit 137, the mesh unit 135, and the cover unit 131 can be separated, which is advantageous in easiness of washing. In addition, when the absorption rate of the absorption section 137 is low, the absorption section 137 can be replaced.

The moving unit 121 is a component for forcibly feeding the food waste toward the discharge port 116 and includes a cylinder 122 disposed outside the moving housing 112 and a cylinder 122 disposed outside the moving housing 112 from the cylinder 122. [ And a piston 123 which is provided so as to be able to expand and contract. The piston 123 may be provided with a pressing part 125 for pressing the food waste. Then, the mobile unit 121 can be installed by a support.

In this embodiment, the piston 123 extends in the diagonal direction along the receiving portion 141 from the inlet 114 side toward the outlet 116 side, and can pressurize the food waste. Accordingly, stagnant food waste can be moved to the discharge port 116 on the upper part of the absorption module placed in each step.

The food waste can be primarily separated from the liquid and solid components while passing through the moving module 110 configured as described above.

However, the above-described configuration of the moving module 110 is only one embodiment, and is not limited to the above.

The liquid component separated from the moving module 110 moves to the leachate module, which only collects the liquid component, and the solid moves to the crushing module 150.

In the pulverizing module 150, the solid matter is pulverized into small particles by repetitive blowing or pressurization and discharged to one side. Then, the liquid component contained in the solid matter is separated by blowing or pressurizing and discharged through the lower part.

More specifically, as shown in FIG. 4, the crushing module 150 of the present embodiment may include a crushing housing 151 and a striking portion 175.

The pulverizing housing 151 may be formed with an inlet 152 through which the solids are introduced through the upper portion, a liquid outlet 155 through which the liquid component is discharged through the lower portion, and a solid outlet 184 through which the solids are discharged through the side. The inside of the crushing housing 151 may be divided into a plurality of crushing spaces along the height direction.

Here, the plurality of grinding spaces may be partitioned by the mesh plates 161, 162, and 163 having different mesh sizes. Further, as the mesh plates 161, 162, and 163 are positioned at the lower part, the mesh size can be reduced.

For example, in the present embodiment, the inside of the crushing housing 151 is divided into three crushing spaces, the mesh of the mesh plate 161 located at the uppermost position is the largest, and the mesh plates 163 ) Can be formed to have the smallest size.

Each of the crushing spaces may be provided with a striking unit 171 for crushing or pressing the solid material by crushing or pressing. The striking unit 171 includes a cylinder 173 and a piston 172 reciprocating horizontally in the cylinder 173 and a striking portion 175 coupled to the end of the piston 172 for directly striking the solids .

The striking portion 175 can move in the horizontal direction and strike the solids.

In each of the crushing spaces, a solid material discharge port 184 through which the solid material is discharged by the horizontal movement of the striking part 175 may be formed. The solids discharge port 184 may be provided with a valve portion 182 for selectively opening and closing the solids discharge port 184.

Accordingly, when the solids are crushed into small particles, the striking unit 175 is driven by the striking unit 171 while the valve unit 182 is closed, so that the striking unit 175 strikes the solids against the valve unit 182, can do. At this time, the solid matter is compressed during the striking process, so that the liquid component contained in the solid matter can move downward through the mesh plate.

Further, when it is desired to discharge the solid matter, the striking unit 171 can be driven with the valve portion 182 opened. The actuation of the striking unit 171 causes the striking portion 175 to move in a horizontal direction and push the pulverized solids into the solids outlet 184.

At this time, in the crushing space located at the uppermost part, some of the crushed solids can move downward through the mesh plate 161. The solid material thus moved to the second grinding space is again pulverized into small particles by the striking portion 175, wherein a part of the pulverized solid material is again moved downward through the mesh plate 162, (184). ≪ / RTI > The solidified material having a reduced particle size through the two pulverization can be pulverized into smaller particles by blowing again in the third pulverizing space and can be discharged through the liquid outlet 155 through the mesh plate 163.

In this way, the solids pulverized by the striking unit 171 are discharged through the solids discharge port 184, and the liquid component generated in this process passes through the plurality of mesh plates 161, 162, 163, And may be discharged to the discharge port 155 and moved to the leachate module 230.

On the other hand, the hitting portion 175 may be provided with a heating portion 177. The heating unit 177 may heat the striking unit 175 to heat the striking unit 175 to heat the liquid contained in the solid when the striking unit 175 is in contact with the solid. In addition, by raising the internal temperature of the crushing housing 151 to generate moisture from the solids, the liquid component can be separated more quickly from the solids.

In addition, a vibration unit 165 for applying vibration to the mesh plates 161, 162, and 163 may be connected to the mesh plates 161, 162, and 163, respectively. The vibrating unit 165 vibrates each of the mesh plates 161, 162, and 163 to separate the solid residues sandwiched between the meshes, thereby smoothly discharging the liquid component.

In addition, a guide 155 that is inclined toward each of the mesh plates 161, 162, and 163 may be provided on the opposite side of the portion where the strike is performed by the strike portion 175. As a result, the solids do not stagnate in the corners, and even pulverization can occur.

The food waste can be separated from the solids and liquid components while passing through the crushing module 150 constituted as described above.

However, the configuration of the crushing module 150 described above is only one embodiment, and is not limited to the above.

The liquid component separated in the crushing module 150 moves to the leachate module 230 where only the liquid component is collected, and the solid moves to the dewatering module 190.

5, the dewatering module 190 separates liquid components contained in the solid matter discharged from the crushing module 150 through centrifugal separation, and includes a dewatering housing 194, a liquid separation housing 210, And a driving unit 222. [

Inside the dewatering housing 194, a solids receiving space 192 may be formed in which the solids discharged from the crushing module 150 are received. A lower portion of the dewatering housing 194 is provided with a support 198 for supporting the dewatering housing 194 and a rotary shaft 197 disposed between the dewatering housing 194 and the support 198 for rotating the dewatering housing 194 .

A liquid separating housing 210 may be coupled to one side of the dewatering housing 194 to form a liquid receiving space 201 in which a liquid component separated by rotation of the dewatering housing 194 is received. The dewatering housing 194 may be formed with a mesh 195 having a plurality of small holes corresponding to the liquid containing space 201.

This causes the liquid component to separate from the solids contained in the solids receiving space 192 as the dewatering housing 194 rotates wherein the separated liquid component is introduced into the liquid containing housing 210 through the mesh 195 And can be accommodated in the space 201.

The drain hole 212 may be formed in the bottom surface of the liquid separation housing 210 so that the liquid component is selectively discharged. The drain hole 212 is closed by the stopper 216 when the dewatering housing 194 is rotated. When the rotation of the dewatering nozzle is stopped, the stopper 216 may be opened to open the discharge hole 212. The liquid component discharged through the discharge hole 212 can be transferred to the leachate module.

Meanwhile, a driving unit 222 for generating a rotational force for rotating the dewatering housing 194 may be provided. Here, the driving unit 222 is a motor, and the dewatering housing 194 is mechanically connected to the driving unit 222 and can be rotated by receiving the rotational force of the driving unit 222.

As a configuration for transmitting the rotational force, for example, a belt 220 may be applied. The drive shaft 224 of the drive unit 222 may be provided with a drive member 226 that rotates together with the drive shaft 224. [ The rotational force of the driving unit 222 can be transmitted to the dewatering housing 194 through the belt 220 by connecting the rotational shaft 197 of the dewatering housing 194 and the driving member 226 by the belt 220 .

The food waste may be separated from the solids and liquid components through the dewatering module 190 as described above.

However, the configuration of the dewatering module 190 described above is only one embodiment, and is not limited to the above.

It will be apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit or scope of the invention as defined in the appended claims. It is obvious to them. Therefore, the above-described embodiments are to be considered as illustrative rather than restrictive, and the present invention is not limited to the above description, but may be modified within the scope of the appended claims and equivalents thereof.
