Description

[0001] Pellet manufacturing device usibg sludge [

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an apparatus for treating contaminants, and more particularly, to a pelletizing apparatus using sludge.

However, the disposal method mainly depends on marine dumping, landfill, and incineration, and a very small part is recycled.

On the other hand, in the case of conventional dumping, only a part of the sludge generated in Korea is involved, and a lot of transportation costs are incurred in disposal, and pollution problems such as pollution of the ocean are serious. As a result, the government is banned from dumping marine dumping altogether after 2012, and in the case of landfill, there is a shortage of landfill sites in a narrow country, and leachate is generated during landfilling, thereby causing secondary pollution to pollute water quality.

Also, in case of incineration, too much heat energy is required for incineration, resulting in enormous expense and odor.

Recently, many attempts have been made to produce fuel materials using such sewage sludge.

Typically, conventionally, in order to produce sewage sludge as a solid fuel, sewage sludge or food waste is dried to a moisture content of 10% or less, mixed with a caloric aid such as coke, anthracite, wood or oil, Respectively.

In addition, the conventional solid fuel technology adopts a method of drying sludge using an external heat source and then mixing the heat assistant or the molding assistant and compressing the sludge at a high pressure.

However, in the fueling technology using conventional sludge, the structure of the apparatus for this purpose is very complicated and inefficient.

In addition, since it is a method of manufacturing solid fuel by firstly consuming a lot of energy to dry sludge, it is not intended to recycle sludge as renewable energy.

The mixing module 110 includes a mixing case 111 having an inner space 114 and an outer appearance of which the sludge and sawdust are connected to the inner space 114 And an outlet 113 through which the sludge mixed with the mixing case 111 and the sawdust are discharged to the outside.

The sludge and sawdust are supplied from the sludge storage tank 102 and the sawdust reservoir 104, respectively, to the inlet 112 through a separate connection pipe 106.

Although not shown, the sludge and sawdust can be transferred to the mixing case 111 by a separate conveyor belt method.

The mixing module 110 includes a mixing blade 115 for mixing the sludge and sawdust introduced into the mixing case 111 by a mixing shaft 116, And the mixing shaft 116 is connected to the driving shaft of the mixing motor 118 provided outside.

That is, according to the operation of the mixing motor 118, the mixing shaft 116 and the mixing blades 115 rotate to mix the sludge supplied into the mixing case 111 with the sawdust. In order to increase the mixing efficiency of the sludge and the sawdust, the mixing blade 115 may have various shapes and a separate mixing blade may be further applied to the blade 115 itself.

The sludge and sawdust mixed by the mixing module 110 move to the drying module 140.

The pelletizing apparatus 100 using the sludge according to the present invention may further include a microbial supply unit 130 disposed on the outlet 113 side of the mixing module 110 for removing odors and the like before the mixture is transferred to the drying module 140. [ (Not shown).

The microorganism supply unit 120 supplies microorganisms to the mixed sludge and the sawdust together with predetermined medicines to remove odors. For this purpose, a separate microorganism reservoir 128 is provided, and the microorganism reservoir 128 And a microbial feed pipe 122 and a valve 124 for connecting the microbial feeder 120 and the microbial feeder 120. [

According to the configuration, the valve unit 124 operates to supply the microorganisms together with the separate chemical solution to the sludge and the sawdust mixed in the spraying manner.

In addition, the microorganism supply unit 120 is connected to a separate air supply unit 130 so that odor and the like may be discharged to the outside. The air supply unit 130 may be one of various known types.

Here, the jetting unit 121 forms a shape in which the number of the mixed sludge and the sawdust are shifted from one side to the other along the direction of movement, thereby minimizing the supply amount, and supplying sufficient amount to the mixed sludge and microorganisms .

Referring to FIG. 1 again, the drying module 140 receives sludge and sawdust mixed from the mixing module 110, and heats the internal temperature to a predetermined temperature to dry the mixed sludge and sawdust.

To this end, the drying module 140 includes a drying case 141 having an inner space 142 and an inlet and an outlet.

A drying blade 143 for rotating the mixed sludge and the sawdust is rotatably installed along with the drying shaft 144 in the drying case 141. The drying shaft 144 is provided with a drying And is axially connected to the drive shaft of the motor 145.

The drying module 140 includes a heating module for supplying high temperature air to the mixed sludge and sawdust and a temperature measurement module 150 for measuring the internal temperature of the drying case 141.

That is, the upper portion of the reflective portion 155 has a predetermined inclined block shape.

The mesh portion 153 and the high-pressure air supply portion 158 prevent the mixed sludge and the sawdust foreign material from flowing around the temperature sensing portion 151, and directly mix the sludge mixed with the temperature sensing portion 151 and the sawdust The high-pressure air supply unit 158 is capable of preventing the temperature of the sludge mixed with the temperature sensing unit 151 from being excessively high, Thereby preventing the fluid from flowing.

Here, the mesh part 153 may be provided to cover the entire temperature sensing part 151, not only the lower part of the temperature sensing part 151.

When the coin tube 160 rotates, it is possible to supply the heated air to the inner side of the drying case 141, thereby increasing the drying efficiency.

The dried sludge and the sawdust mixture, which have been dried through the drying module 140, are introduced into the pellet forming module 180 as shown in FIG. 1 and processed into pellets having a predetermined shape. The pellet molding module may be of any one of various known types, and a detailed description thereof will be omitted.

As described above, according to one embodiment of the present invention, the inside of the drying case 141 can be efficiently dried in a short time by using the coin pipe 160 in the drying module 140, And the drying efficiency can be increased.

In addition, when the coin tube 160 is rotated, the secondary mixing process of the sludge and the sawdust can be performed, and uniform drying air can be supplied to the entire drying case.
