Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a double-walled double-walled structure for processing dead livestock,

The present invention relates to a double-walled tank that is buried underground in order to treat waste shafts without environmental pollution.

When communicable diseases such as pig cholera, mad cow disease, and bird flu occur, many of the livestock that are being raised in the farm are killed or disposed of to prevent the spread of infectious diseases. It has been common for massive dead axes caused by infectious diseases to be buried underground or incinerated because they are inadequate for food. In the case of the conventional shaft milling by incineration, the smoke generated at the time of incineration pollutes the atmosphere and a considerable cost is required, so that there is a limit to deal with a large number of dead shaft. Conventionally, it has a merit of being able to treat a large number of dead shafts at one time, but it has a problem that harmful gas generated from corruption and a large amount of leachate may contaminate the environment.

In order to solve these problems, Korean Patent Registration No. 10-1032605 entitled " Environmentally friendly buried container for treating dead or deadly livestock, " Korean Patent No. 10-1187165 entitled " 10-1190635 "a barrel for the treatment of our livestock" has been proposed. However, according to the above-mentioned prior arts, it is difficult to smoothly discharge the gas and leachate generated from the dead shaft, or a complicated type of equipment is additionally required in order to discharge the gas and leachate generated from the dead shaft, There is a problem that it takes a lot of cost to construct the facility.

Double-walled structure is used to discharge gas and leachate generated from the shaft of the ship, without any additional equipment, without polluting the environment at low cost, And to provide an axial treatment tank. Further, the present invention is not limited to the above-described technical problems, and another technical problem may be derived from the following description.

According to one aspect of the present invention, a dead-end shaft processing tank of a double-walled structure buried in an underground has a pipe-shaped outer wall, a pipe-shaped inner wall having an outer diameter smaller than the inner diameter of the outer wall, A tank body having a double wall structure in which ring-shaped partition walls arranged at intervals are integrally formed, and a plurality of openings communicating with some of the passages existing between the partition walls are formed on the inner wall; A plurality of passageways joined to a surface of an outer wall around an incision region of the tank body including a plurality of passages between the outer wall and the inner wall communicating with a plurality of openings of the inner wall, At least one manhole tube; And tank side plates joined to both side ends of the tank body to seal the both side ends.

Wherein the dead-end shaft processing tank further includes a mounting member installed in an internal space of a dead-end shaft processing tank formed by the tank body and the tank side plates, A plurality of holes may be formed for allowing the leachate to pass therethrough. The spent shaft treatment tank may further include a mesh-type bag that is loaded on the mounting member and receives the waste shafts and through which the leachate can pass.

Wherein a plurality of openings in the inner wall are formed at positions corresponding to both ends of an inner diameter diameter of an inner wall of a space in which the mortise shaft is held at the same distance from the surface of the stationary member, The size of the bag surface in the maximally swollen state may not be in contact with the plurality of openings of the inner wall. The inner wall may further include a plurality of openings communicating with the plurality of passages at positions at the deepest depth of the inner wall, in addition to the plurality of openings of the inner wall.

Wherein the tank body further includes a plurality of rings attached to the inner surface of the inner wall at a distance less than a distance from the charging port along the periphery of the charging port, The entrance perimeter of the bag may be secured by the plurality of rings. A tension coil spring may be inserted between each of the plurality of rings and each of the holes formed around the inlet of the bag. Wherein the mounting member is a pile of a plurality of piles which are piled up to a predetermined depth of the inner space of the dead-end shaft processing tank deeper than the depth of the plurality of openings of the inner wall from the deepest point of the inner space of the dead- Lt; / RTI >

The spent shaft treatment tank may further include a disk-shaped filter having an outer wall screwed into the inner wall of the inlet of the vent pipe to purify gas generated from the dead shaft. A heating element including at least one of a heat ray and a heating paint is attached or coated on a surface of the inner wall, and a power source required for heat generation of the heating element can be supplied from a solar panel installed on the ground. Wherein the tank body, the at least one manhole tube, and the entire tank side plates and a part of the at least one vent pipe are buried underground, and the other ends of the at least one vent pipe are exposed on the ground.

In order to improve the durability and insulation effect of the tank, the double-walled internal passage adopted is used as a gasoline, leachate, It is possible to manufacture a large-sized dead-end shaft treatment tank which can complete the corruption of a large amount of the shaft at a low cost.

In particular, only by adding the openings of the inner wall of the tank of the double-walled structure, it is possible to secure a channel for transporting any amount of gas and leachate generated in the dead shaft. Since all the parts except for the part of the ventilation pipe are buried in the underground tank, the superficial shale shaft treatment tank almost does not consume the ground space due to the super large shale shaft treatment tank.

In addition, not only a mounting member for separating the leachate generated from the dead shaft from the dead shaft is installed inside the tank, but also the dead body corruption can proceed quickly due to the latent heat underground. Further, the inner wall of the dead-end treatment tank may be coated with a heating element such as a heat ray, a heat-generating paint, or the like, so that the dead body decay can proceed more quickly. A pile of piles piled up from the bottom of the tank is a low cost mounting piece that can withstand a very large load on the mortise shaft.

In addition, the mesh-type bag which is loaded on the mounting member and receives the waste shafts and through which the leachate can pass can prevent the clogging of the openings of the inner wall by the dead shaft so that the dead ends do not come into direct contact with the inner wall of the tank, It is possible to smoothly discharge the gas generated from the dead shaft and supply the oxygen required for the shaft decay. In particular, since the mesh bag is fixed by the rings attached to the tank inlet, the operator can install or withdraw the mesh bag without entering the tank.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

1 is a perspective view of a spent shaft treatment tank according to an embodiment of the present invention. 1, the spent shaft treatment tank according to the present embodiment includes a large-diameter pipe-type tank body 10 having a double-walled structure in which a charging port 101 into which waste shafts are inserted is formed, Shaped tank side plates 20 which are joined to the tank body 10 and seal both side ends thereof, manhole tubes 30 of a small-diameter pipe type having a double wall structure joined to the outer surface of the tank body 10, manhole tubes 30 The lid 50 covering the inlet 101 of the tank body 10 and the tank side plates corresponding to the deepest position of the inner space of the tank body 10 20 as a main component. The additional construction of the dead-end processing tank shown in Fig. 1 will be described in detail in the following section.

As shown in FIG. 1, the charging port 101 may be formed by cutting a part of the tank body 10 into a square hole. The rectangular plate of the double wall structure separated from the tank body 10 by such an incision can be used as the lid 50. The incision surface of the charging port 101 may be reinforced with a material such as stainless steel, titanium or carbon which is strong against rust, and the lid 50 is integrally formed on the incision surface of the charging port 101, Is formed on the lower surface of the base plate. The lid 50 is provided with a handle so that the operator can open or close the lid 50 by using a handle attached to the lid 50. [

Although two manhole tubes 30, two vent pipes 40 and one discharge pipe 60 are shown in FIG. 1, this is only an example, and the spent shaft treatment tank according to the present embodiment may have one or three or more A manhole tube, one or more than three vent pipes, and a plurality of discharge pipes. The whole of the tank body 10, the manhole tubes 30, the tank side plates 20 and the discharge tube 60 and a part of the ventilation tubes 40 are buried in the basement, The spent shaft treatment tank shown in Fig. 1 is buried in the basement.

2 is a longitudinal sectional view of the spent shaft treatment tank shown in Fig. The tank side plates 20 are omitted in order to easily grasp the internal structure of the spent shaft treatment tank shown in Fig. As shown in Fig. 2, the tank body 10 of the dead end treatment tank shown in Fig. 1 has an outer wall in the form of a large diameter pipe, an inner wall in the form of a pipe having an outer diameter smaller than the inner diameter of the outer wall, And the ring-shaped barrier ribs having a rectangular cross section arranged at regular intervals in the direction of the barrier ribs are integrally formed.

The double wall of the tank body 10 may be made of a material of high density polyethylene. High-density polyethylene is one of the high-molecular compounds produced by the polymerization of ethylene and is polyethylene having a density of 0.95 or more. The high-density polyethylene is very suitable for the material of the shaft treatment tank embedded in the underground because it has excellent chemical resistance, heat resistance and cold resistance due to the chemical nature of the material. However, since the high-density polyethylene is difficult to process, the double-walled tank body 10 can be manufactured by extrusion molding. Such an extrusion molding method is advantageous for making a very large tank because it does not require the production of a large mold. As shown in FIG. 1, on the surface of the tank body 10, a spiral pattern generated in the extrusion molding process is continuously formed.

Due to the double wall structure of the tank body 10 as described above, ring-shaped passageways of rectangular cross section exist between the partition walls of the double wall of the tank body 10. The cross-section of such a passage is shown in the double wall section shown in Fig. To clearly show the double wall cross-sectional structure, the outer wall, the inner wall, the partition, and the passageway are shown in Fig. When an impact is applied to the outer wall of the tank body 10, the impact can be absorbed by these existing hollow passages between the outer wall and the inner wall. Thus, the double wall structure of the tank body 10 improves the durability of the spent shaft treatment tank shown in Fig. The high-strength structure of such a double wall is not deformed or broken even under the load of a large-sized vehicle, so there is little risk of leakage of leachate.

Generally, the inner walls of the double wall of the tank body 10 are filled with air, and since the air has a lower thermal conductivity than the high density polyethylene, the double wall structure of the tank body 10 has the warmth of the dead end treatment tank shown in FIG. . In addition, since the high-density polyethylene belongs to a material having a very low thermal conductivity, it can be seen that the thermal insulation effect of the double-walled pulverulent shaft treatment tank is excellent. Due to such a thermal effect, the interior of the shaft treatment tank is maintained at a temperature at which microbial activity can actively take place, thereby providing an environment in which corruption of the carcass can proceed smoothly. Particularly, since almost all the parts of the spent shaft treatment tank shown in FIG. 1 are buried in the underground, the spent shaft treatment tank is affected by latent heat in the underground, and the microorganism activity inside the spent shaft treatment tank can be actively Lt; / RTI >

As shown in FIG. 2, on the inner wall of the dead-end shaft tank according to the present embodiment, a plurality of openings 1021 communicating with some of the passages existing between the partitions are formed, A portion of the tank body 10 including a plurality of passages between the outer wall and the inner wall communicating with the inner wall 1021 is cut in the shape of a circular hole. Two such incision regions 103 are formed in the tank body 10 shown in Fig. Two pairs of three openings 1021 are formed on the inner wall of each cut-off region 103 of the tank body 10, but this is only an example. Considering the size of the manhole tubes 30 through which a person can pass, A much larger number of openings are formed on the inner wall for each cut-out region 103 of the substrate 10.

The gas generated from the dead shaft inside the dead-end treatment tank may flow into the openings 1021 of the inner wall to flow through the passages inside the double wall and out the passage outlets of the cut surface of the double wall. In addition, the oxygen required for the dead shaft decay may be introduced into the passage outlet of the cut-off wall of the double wall, and may be supplied to the interior of the dead-end processing tank through the openings 1021 of the inner wall through the passages inside the double wall. As described above, according to the present embodiment, the inner passage of the double wall structure adopted for improving the durability of the tank and the heat insulation effect is used as a transportation passage of oxygen required for gas, leachate, It is possible to fabricate a very large dead-end shaft treatment tank at a low cost without the fear of environmental pollution. In particular, only by adding the openings of the inner wall of the tank of the double-walled structure, it is possible to secure a channel for transporting any amount of gas and leachate generated in the dead shaft.

Each of the manhole tubes 30 is joined to the surface of the outer wall around the incision area 103 of the tank body 10 including a plurality of passages between the outer wall and the inner wall communicating with the plurality of openings 1021 of the inner wall, The inside passages are collected and connected to one vent pipe 40. Some of the passageways in the double wall may be clogged in the process of manufacturing or using double walled pipes. In this embodiment, a plurality of passages inside the double wall are connected to one vent pipe 40 through the manhole tubes 30 in order to ensure more complete ventilation of the spent shaft treatment tank. In addition, since each of the manhole tubes 30 has an inner diameter of a size allowing a person to pass through, the inside of the spent shaft treatment tank can be easily cleaned or repaired.

The manhole tubes 30 can be made in a double-walled structure of high-density polyethylene material like the tank body 10. The tank side plates 20 are fabricated in the form of flat discs of high density polyethylene material, and this type of high density polyethylene is fabricated as a single wall structure since it is difficult to manufacture with a double wall structure. And the leachate generated from the dead shaft becomes deepest in the inner space of the dead-end shaft treatment tank shown in Fig. In order to extract such leachate to the outside of the spent shaft treatment tank, at least one of the tank side plates 20 is formed with a discharge port, which is a circular hole having the lowest point of the circumference at the deepest depth of the inner wall surface of the spent shaft treatment tank , And a discharge pipe (60) through which the leachate is discharged is connected to the surface of the tank side plate around the discharge port.

When leachate is mixed in the shaft, the amount of oxygen contacted with the shaft is reduced, so that corpse decay due to aerobic microorganisms does not proceed smoothly. Accordingly, the leachate generated in the dead shaft needs to be separated from the dead shaft. In order to separate the leachate from the dead shaft, leachate having a volume corresponding to one tenth of the total volume of the dead shaft is generated in the dead shaft. Therefore, a space occupying one tenth of the internal volume of the dead- .

In order to separate the leachate from the dead shaft and to secure the storage space of the leachate, a mounting member on which the dead ends of the shaft are mounted is formed by the internal space of the dead shaft treatment tank, that is, the tank body 10 and the tank side plates 20 It can be installed in the inner space of the tank. As such a mounting member, a rectangular porous plate having a plurality of holes for allowing the leachate from the dead ends to pass therethrough may be used. The inside of the spent shaft treatment tank shown in FIG. 1-2 has a structure that becomes narrower in the downward direction, that is, downward, so that the height at which the perforated plate is installed can be adjusted according to the size of the perforated plate.

FIG. 3 is a view showing a perforated plate 111 installed in the dead-end shaft treatment tank shown in FIGS. 1-2, and FIG. 4 is a sectional view of the dead- Sectional view. When the leachate flows into the openings 1021 of the inner wall, the discharge of the gas generated from the dead shafts through the openings 1021 of the inner wall and the supply of oxygen necessary for decay of the dead shaft are not smoothly performed. In order to prevent the inflow of the leachate into the openings 1021 of the inner wall, as shown in Fig. 4, a dead-end shaft process which is deeper than the depth of the openings 1021 of the inner wall of the dead- A rectangular perforated plate 111 may be provided at a predetermined depth in the inner space of the tank at the same circumference as the perimeter of the inner circumferential surface of the dead end treatment tank corresponding to this depth.

Particularly, in order to secure a space occupying one-tenth of the internal volume of the spent shaft treatment tank as a leachate storage space, the depth of the inner volume of the inner shaft processing tank and the depth of the openings 1021 of the inner wall A rectangular perforated plate 111 may be provided at a predetermined depth between the depths and at the same circumference as the circumference of the inner circumferential surface of the dead end treatment tank having the same constant depth. The periphery of the perforated plate 111 may be adhered to the inner surface of the dead-end shaft treatment tank by using an adhesive or the like to prevent the flow of the perforated plate 111. As shown in FIG. 4, in the space below the perforated plate 111, there is a leached water leaking from the holes of the perforated plate 111.

FIG. 5 is a view showing a perforated pipe 112, which is a unit component of a pile of a perforated pipe installed in the dead end treatment tank shown in FIG. 1-2, and FIG. 6 is a cross sectional view showing the perforated pipe 112 shown in FIG. Is a cross-sectional view of a spent shaft treatment tank in which a pile (113) of pores for a constituent element is installed. Since the perforated plate 111 shown in FIG. 4 is a place where the dead end shaft is loaded, a considerably large load is applied. Accordingly, the perforated plate 111 must be custom-made of expensive engineering plastic material. Instead of such a perforated plate 111, a dummy 113 of the pipe tubes may be used as a mounting member on which the dead ends are mounted. Inexpensive yet rigid pore tubes of various sizes are readily available on the market. As shown in Fig. 5, the pipe tube 112 is a pipe having a plurality of holes formed therein.

As shown in FIG. 6, in order to prevent the inflow of the leachate into the openings 1021 of the inner wall, the dummy 113 of the pipe tubes is inserted from the deepest part of the inner space of the dead- Can be piled up to a predetermined depth of the inner space of the dead-end shaft processing tank deeper than the depth of the openings 1021 of the openings 1021. [ Particularly, in order to secure a space occupying a tenth of the internal volume of the spent shaft treatment tank as a leachate storage space, the piles 113 of the pipe tubes are connected to the deepest portion of the inner space of the spent shaft treatment tank, It can be piled up to a predetermined depth between the depth of the inner volume 10 and the openings 1021 of the inner wall. In order to prevent the flow of the oil holes, the oil holes are adhered to each other using an adhesive or the like, and the oil holes of the oil holes of the oil hole pile 113, which are in contact with the inner surface of the used oil treatment tank, may be adhered to the inner surface of the used oil treatment tank.

Since the load of the dead shaft applied to the pile pipe 113 is dispersed in each of the plurality of pipe tubes, the load applied to one pipe tube becomes small. The leachate generated from the dead shaft seeps into the holes of the oil holes constituting the uppermost layer of the oil hole dummy 113 and the leachate impregnated into these oil holes is discharged from the holes of these oil holes and then permeated into the holes of the oil holes below . As a result, the leachate is accumulated in the pores of the height of the leachate existing in the inner shaft treatment tank. As described above, the pile pipe 113 is a low-cost mounting member capable of withstanding a very large load of the dead shaft.

When the dead ends are piled up on the mounting member such as the perforated plate 111, the pile pipe 113, etc., the openings 1021 of the inner wall can be clogged by the dead ends, The discharge of the gas generated from the shafts and the supply of the oxygen required for decay of the dead shaft may not be performed smoothly. As shown in Figs. 4 and 6, a mounting member such as a perforated plate 111, a pillar 113, or the like can be loaded with a bag-shaped bag 12 that can receive the leaking water and pass the leaking water .

The mesh sack (12) is a bag of fabric structure in which a plurality of chemists are interwoven with weft and warp yarns. The leachate generated from the shaft of the ship is discharged through the gap of the mesh net 12 formed at the intersection of the weft yarn and the warp yarn, and the tensile force of the weft yarn and the tension of the warp yarn It can support the weight of our shaft. Since the shaft shafts are contained in the mesh bag 12, the shaft shafts do not come into direct contact with the inner wall of the dead shaft treatment tank shown in Figs. 1-2 and the clogging of the openings 1021 of the inner wall by the shaft shafts So that the discharge of gas generated from the dead ends through the openings 1021 of the inner wall and the supply of oxygen necessary for the dead spots of the dead ends are smoothly performed.

However, there is a possibility that the openings 1021 of the inner wall are clogged by the portions of the netting bag 12 still filled with the dead ends. In order to more completely prevent clogging of the inner wall openings 1021 due to the dead ends, the openings 1021 of the inner wall are arranged at the same distance from the surface of the mounting member such as the perforated plate 111, And it is preferably formed at positions corresponding to both ends of the inner diameter of the inner wall of the space in which the dead shaft is mounted on the stationary member.

4 and 6, the size of the netting bag 12 is preferably such that the surface of the bag is not in contact with the openings 1021 of the inner wall when the netting bag 12 is fully inflated Do. The surface of the netting bag 12 does not come in contact with the openings 1021 of the inner wall even if the netting bag 12 is inflated to the maximum due to filling of the netting rod 12 with the dead axis up to the maximum capacity limit of the netting bag 12 do. Thus, clogging of the openings 1021 of the inner wall by the dead ends can be more completely prevented.

On the other hand, even if clogging of the openings 1021 of the inner wall by the dead ends is prevented, when the dead springs are continuously accumulated in the mesh bag 12, the leachate generated from the dead springs located higher than the openings 1021 of the inner wall It can flow into the openings 1021 of the inner wall. Thus, the leachate flowing into the openings 1021 of the inner wall continues to be accumulated below the passages connected to the openings 1021. In addition to the openings 1021, the inner wall of the tank body 10 is provided with a passage (not shown) at the deepest depth of the inner wall to connect the openings 1021 to the inner wall of the tank body 10 to draw out the leachate accumulated in the passage connected to the openings 1021 of the inner wall. A plurality of openings 1022 communicating with each other may be additionally formed.

In addition, in order to further improve the ventilation of the dead-end treatment tank and to ensure the ventilation of the dead-end treatment tank even when some of the openings are clogged due to some causes, A plurality of openings 1023 communicating with the openings 1021 and 1022 and communicating with the openings 1021 and 1022 of the tank body 10 and communicating with the openings 1021 and 1022 are provided between the openings 1021 and 1022, And a plurality of openings 1024 communicating with the passages connected to the openings 1021 and 1022 between the openings 1021 located at the middle and the openings 1022 located at the bottom of the tank ) May be additionally formed.

Since most of the material constituting the animal is water, as the spoilage of the ship shaft progresses, the volume and weight of the ship shaft is greatly reduced if most of the leachate is discharged from the shaft. When the dead shaft contained in the mesh bag 12 is completely corroded, the volume and the weight of the mesh bag 12 are greatly reduced, and the mesh bag 12 can be taken out from the inlet 101 with less force. As shown in Figs. 4 and 6, in order to facilitate the withdrawal of the netting bag 12, a plurality (not shown) of the plurality of netting bags 12 attached to the inner surface of the inner wall less than a predetermined distance from the charging port 101 along the periphery of the charging port 101 The perimeter of the netting bag 12 can be fixed by the hooks 1141 of the hooks 1141. [

Since the spent shaft treatment tank according to the present embodiment is a large-capacity tank embedded in the basement, if the operator has to enter the inside of the tank for installation or withdrawal of the mesh bag 12, the operator can avoid the risk of accidents The risk of infection by the pathogenic bacteria of the dead shaft existing in the tank. The hooks 1141 for fixing the periphery of the netting bag 12 are attached along the periphery of the charging port 101 to the inner surface of the inner wall less than a certain distance from the charging port 101, The operator does not enter the tank and puts his / her hand into the inlet 101 from the outside of the tank, that is, from the ground, and hooks the fixing portions of the bag to the rings 1141 around the inlet 101, The mesh bag 12 can be easily installed or taken out from the inside of the tank.

Fig. 7 is a view showing parts used for attaching the inner wall of the tank body 10 of the netting bag 12 shown in Figs. 4 and 6. Fig. 7 is a perspective view of a portion of the mesh body 12 in which the mesh body 12 is joined to the inner wall of the tank body 10 in order to more clearly show the parts used for attaching the mesh body 12 to the inner wall of the tank body 10. [ Only a part thereof is shown. 7, a netting bag 12 is provided between each of the rings 1141 attached to the inner wall of the tank body 10 and the holes 1143 formed around the inlet of the netting bag 12, 1142 are inserted. Both ends of the tension coil spring 1142 are formed in the form of hooks so that both ends of the tension coil spring 1142 are fixed to the inner wall by the hooks 1141 and the holes formed around the inlet of the mesh bag 12 1143, respectively.

The impact of the mesh bag 12 can be reduced by the elasticity of the spring 1142 even if the mortise shaft 12 thrown by the operator is impacted on the mesh bag 12, The breakage of the mesh 1141 and the mesh bag 12 can be prevented. In order to prevent the mesh bag 12 from being split by the pressure applied to the holes 1143 of the netting bag 12, the holes 1143 are formed with a rust-resistant material such as stainless steel, titanium, A ring of carbon or the like can be packed. The rings 1141 attached to the inner wall of the tank body 10 can also be made of a hard and strong material.

The optimal temperature at which aerobic microorganisms causing corpse decay can be actively grown is known to be between 20 and 30 degrees. Therefore, if the internal temperature of the spent shaft treatment tank shown in Figs. 1-2 can be maintained between 20 and 30 degrees, the complete decay of the carcass can be completed in a shorter time. In order to ensure that the internal temperature of the spent shaft treatment tank installed in one or the temperate zone is always maintained between 20 ° C and 30 ° C, a heating element such as a heat ray or a heating paint may be adhered or coated on the inner wall of the shaft treatment tank .

Power must be supplied to heat the heating element. Commercial power supply supplied from the electric power company can be used as a power source for heat generation of the heating element. However, the used shaft treatment tank is installed in a mountain area where there is no humanity due to air pollution caused by gas, And commercial power is not supplied to these areas. According to the present embodiment, the power source required for heat generation of the heating element can be supplied from a solar cell panel (not shown) installed on the ground. The auxiliary device necessary for power supply using the solar panel is well known to those skilled in the art, so a detailed description thereof will be omitted.

8 is a view showing a filter installed in the vent pipe 40 of the spent shaft treatment tank shown in Figs. 1-2. 8 (a) is a longitudinal sectional view of the vent pipe 40 equipped with the filter, and Fig. 8 (b) is a perspective view of the filter separated from the vent pipe 40. Fig. As shown in FIG. 8, a disk-shaped filter 41 for purifying the gas generated from the dead shaft may be mounted at the inlet of the vent pipe 40. Such a filter 41 should generally be manufactured so that the operator can be easily separated from the inlet of the vent pipe 40 on the ground because the lifetime is short due to the adsorption in the filtering process and needs to be frequently changed.

8 (a), the inner wall of the inlet of the vent pipe 40 is formed with a female screw mountain with a predetermined depth, and a portion of the outer wall of the filter 41 mounted on the inlet of the vent pipe 40 Respectively. A part of the outer wall of the filter 41 can be screwed to the inner wall of the inlet of the vent pipe 40 by inserting the filter 41 into the inlet of the vent pipe 40 by rotating. The outer wall of the filter 41 is flattened by the height of the thread formed on a part of the outer wall of the filter 41 so that it can not be inserted into the inlet of the ventilation pipe 40 beyond the depth of the part. The operator can hold the outer wall of the filter 41 and rotate the filter 41 so that the filter 41 can be inserted into or separated from the inlet of the ventilation pipe 40.

8 (b), the filter 41 mounted at the inlet of the vent pipe 40 includes a filter net 411 in the form of a disk that allows air to flow in and out, and a female screw 411 formed in the inner wall of the inlet of the vent pipe 40 And a fixed frame 412 having an outer wall having a predetermined number of threaded threads and surrounding the filter net 411. The filter net 411 is pressed into the fixed frame 412 and the filter net 411 is fixed. The filter net 411 can be made of a fabric material to which activated carbon is added. Activated carbon is widely used to remove harmful gases and odors.

9 is a view showing an installation example of the dead-end shaft processing tank shown in Figs. 1-2. 9, the whole of the tank body 10, the manhole tubes 30, the tank side plates 20, and the discharge tube 60 and a part of the ventilation tubes 40 are buried underground, The pulverized shaft treatment tank shown in FIG. 1-2 may be buried in the ground so that the crests of the crests 40 are exposed on the ground. Therefore, only a part of the ventilation pipes 40 is exposed on the ground, so that the ground space is not consumed by the very large dead-end shaft treatment tank of a volume capable of storing a maximum of 50 tons of water. The upper surface of the ground in which the shaft treatment tank is buried may be used as agricultural land for cultivating crops.

In the example shown in Fig. 9, in order to introduce the dead shaft into the dead-end shaft treatment tank and to collect the residue after the dead shaft decay, the soil covering the dead-end shaft treatment tank must be digged so that the inlet 101 of the dead- do. This is not a big inconvenience considering that our shaft decay period is long term. However, in the environment in which the waste shafts are frequently charged and the residuals are required to be collected, the lid of the manhole tubes 30, the lid 50 of the charging port 101 of the spent shaft processing tank, The spent shaft treatment tank may be buried underground.

As described above, the inner bottom of the spent shaft treatment tank shown in FIG. 1-2 is connected to the discharge pipe 60 attached to one of the tank side plates 20, and the leached water on the inner bottom is discharged through the discharge pipe 60 . The discharge pipe 60 of the used shaft treatment tank is connected to the pump 80 located on the ground via the transfer pipe 70. The pumped operation of the pump 80 causes the pumped leachate on the inner bottom of the used shaft treatment tank And sent to the purification facility. Like the power source necessary for heat generation of the heating element, the power source of the pump 80 may be a commercial power source, but a power source supplied from the solar cell panel may be used.

On the other hand, when the spent shaft treatment tank shown in FIG. 1-2 is manufactured as a very large volume capable of storing a maximum of 50 tons of water, it is less likely to collect the leachate toward the discharge pipe 60 A magic pump 80 is required. In order to collect the leachate toward the discharge pipe (60), the inner bottom of the spent shaft treatment tank may be made slightly inclined or the spent shaft treatment tank itself may be buried in the underground at a slight inclination. As described above, the spent shaft treatment tank can also be used as a rainwater storage tank for securing water resources that are insufficient in case of emergency.

The present invention has been described above with reference to preferred embodiments. It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense. The scope of the present invention is defined by the appended claims rather than by the foregoing description, and all differences within the scope of equivalents thereof should be construed as being included in the present invention.
