Description

Scrap two-stage dewatering unit {a device that dehydrates and transports garbage in two stages}

The present invention relates to a two-stage dehydration transfer device for allowing the sediment to be stored separately in a form that can be reprocessed or disposed of after the water is separated again from the sewage or wastewater filtered.

The present invention relates to a two-stage dewatering transfer device for a contaminant that can be used in various sewage treatment plants and wastewater purification facilities. In the case of the conventional wastewater and wastewater purification facilities, the following forms have been utilized.

In practice, wastewater may contain various contaminants, such as manure, manure, food waste, etc., which can be absorbed and decomposed in water, plastics, resin wrappers, and disposable diapers for children, which are difficult or impossible to absorb or decompose in water. , Wipes and so on. The present invention relates to a conveying apparatus for processing a complex of a kind that is difficult to be absorbed and difficult to decompose into the latter double water, and similar inventions have been developed in the past.

That is, Figure 1 shows a conventional patented water dehydration device, the operation is as follows. First, miscellaneous matter containing moisture from the wastewater flows into the hopper 110. It is introduced into the body portion 120 through the neck portion 113 via the taper portion 112. Such contaminants may be a mixture of wetted vinyl, sanitary napkins, diapers, hair, cloth, and the like, as described. The contaminants enter into the body portion 120 while agglomerating with each other, and thus the contaminant conveying unit 130 operates the hydraulic cylinder 131 and the operation rod 132. That is, while the operating rod 132 is extended to push the compression cylinder 133 in the direction of the screen unit 140 and the contaminant discharge unit 150 to press the introduced contaminants.

In this case, the compacts pressurized by the compression container 133 are compressed by the backing pressure formed by the compression taper of the contaminant discharge unit 151 and the inner wall of the cover 152a formed in the contaminant discharge unit 150. As the water escapes (dehydrates). The water coming out is discharged through the dehydration hole 141 of the screen unit 140. The compression barrel 133 is composed of a hollow compression body 133a and a compression plate 133b. In addition, the screen unit 140 is further provided with a screen cleaning brush 160 for cleaning the dewatering hole 141 so as not to be blocked by the debris.

In conclusion, the present invention takes the method of dehydrating the contaminants in the dehydration hole by using the pressure of the hydraulic cylinder, instead of the conventional method of dewatering the contaminants through the dehydrator using the gearing force of the gear. It is an invention that is hard to achieve great effects. In many cases, the soil contains sand and soil, and this type of dehydrator may be used to sort only water, but it is difficult to sort soil or sand. In addition, it is questionable whether the perfect dehydration of moisture can be performed smoothly.

2 to 7, the one end hopper 41 into which the sewage inflow contaminant A is introduced, and the one end of the contaminant A in the form of a transfer pipe connected to the first hopper 41. The transfer tube 43 is formed with a discharge tube 42 is discharged, the transfer screw 46 for rotating the contaminated material (A) formed and formed in the inner side of the transfer tube 43 to the tube discharge portion 42 The water 22 formed in the bottom surface of the transfer tube 43 to discharge a plurality of first stage dehydration holes 47 for discharging water and the transfer tube 43 and discharged to the first stage dehydration holes 47 is formed. Body 49 having a drain 48 for draining separately, the first stage dehydrator 40 is formed by combining; Two-side hopper 51 for receiving the first dehydrated contaminants (A) falling from the tube discharge section 42, the long end in the form of a long tube in communication with the two-stage hopper 51, the hydraulic cylinder ( 52 is coupled and the other end is the two-stage feed pipe 53 and the communication with the two-stage feed pipe (53) in communication with the two-stage feed pipe (53) to be raised to a certain height and to extend to the side storage hopper 70 The pipe consists of a plurality of two-stage dehydration holes 55 at the bottom of the end of the two-stage feed pipe 53, which is a part connected to the rising pipe part 60 and the rising pipe part 60, including the straight pipe 61 and the horizontal pipe 62. When the piston 56 of the hydraulic cylinder 52 is interlocked and transfers the contaminants A dropped to the two-stage hopper 51 to the rising tube portion 60 through the two-stage transfer pipe 53, the rising tube portion 60 The pressure of the piston 56 of the hydraulic cylinder 52 that presses the gravity A and interlocks in the horizontal direction and interlocks in the horizontal direction with the weight of the gravity A being pressed perpendicular to the pressure A two-stage dehydrator 50 for dehydrating water into the two-stage dehydration hole 55; A storage hopper 70 formed at the end of the horizontal pipe 62 of the rising pipe part 60 to store only the contaminants A which are dehydrated; It is made of a two-stage dehydration conveying device for forming an effective classification of the contaminants (A) and water.

Substantially, the present invention has only the action of the transfer screw 46 and the hydraulic cylinder 52 for the transfer, but this action is produced once, such as the tapered inner circumferential surface or the structure of the passage to be transported, natural gravity, and the form of the transfer screw. It is a two-stage dewatering transfer device that can be combined organically with fixed values that do not change, to facilitate the transfer operation of the contaminants, as well as the dewatering and sorting of soil or dust. The present invention largely consists of a first stage dehydrator 40, a second stage dehydrator 50, and a storage hopper 70. The first stage dehydrator 40 dehydrates primarily the contaminants A introduced into the first stage hopper 41 to the second stage dehydrator 50. The conveying screw 46 is required for this conveying. As shown in FIG. 2, the conveying screw 46 has the rotating blade 82 so that the contaminants A sandwiched between the two blades of the dehydrator 50 are removed. It is pushing in the direction of the hopper 51. The present invention is so that the transfer screw 46 can be dehydrated neat moisture of the contaminants (A) only by the operation of rotating. This will be described in more detail with reference to FIGS. 2, 3 and 5.

As shown in Figs. 2 and 3, the complex A of the present invention may be subjected to a process of being crushed or cut in the pretreatment process. After this process, the miscellaneous material A is introduced into the illustrated first stage hopper 41. Injected contaminants A fall into the inside of the feed tube 43 in communication with the first stage hopper 41. Since the conveying screw 46 installed in the horizontal direction is rotated inside the conveying tube 43, the conveying material A is rotated little by little. The feed screw 46 is rotated by the motor 45 and the chain (a), and transports the contaminants (A). At this time, the contaminant A rotates and large friction is generated inside. That is, friction with the blade 82 of the transfer screw 43, the friction (A) is mixed with each other, the friction is generated. In this process, the water 22 inside the contaminant A is dehydrated, and sand or soil is shaken off and falls to the bottom of the transfer tube 43. The lower end of the transfer tube 43, that is, the lower surface, is formed with a plurality of first-stage dehydration holes 47. The water 22, soil, sand, etc. flowing out of the first-stage dehydration holes 47 are transferred to the transfer tube ( 43 is discharged into a separate drain 48 to the inner side of the body 49 surrounding, a small amount of sand or soil may undergo another sorting process.

Meanwhile, the water 22 and the sand or the soil are naturally sorted, and at the same time, the contaminant A, which rotates inside the transfer tube 43, moves in accordance with the operation of the transfer screw 46 to end the transfer tube 43. It is delivered to the two-stage hopper 51 of the two-stage dehydrator 50 through the phosphorus tube discharge part 42.

The two-stage dehydrator 50 is a hydraulic cylinder 52 powered by a separate dehydrator consisting of a two-stage hopper 51, a two-stage feed pipe 53, a rising pipe part 60, and the like. When the hydraulic pressure is transmitted through the hydraulic unit (D) of FIG. 2, the hydraulic cylinder 52 extends the shaft 21 to press and squeeze the contaminant A. FIG. That is, the two-stage hopper 51 is in a state of communicating with the two-stage transfer pipe 53 in the downward direction, and the side of the two-stage hopper 51 is in communication with the hydraulic cylinder 52. Therefore, the contaminant A introduced into the two-stage hopper 51 receives the contaminant A in the state in which the shaft 21 of the hydraulic cylinder 52 is reduced and receives the contaminant A when the shaft 21 is extended. It is delivered to the other side of the two-stage transfer pipe (53). A rising pipe portion 60 is formed at the end of the two-stage transfer pipe 53, leading to a rising pipe portion 60 which is bent and extended at the end of the lower two-stage transfer pipe 53 as shown in FIG. 4.

The rising pipe part 60 is formed of a vertical pipe 61 and a horizontal pipe 62, and raises the contaminant A in the vertical direction, and moves it in the horizontal direction to accommodate the inside of the storage hopper 70. Make sure

4 and 6 are shown in detail the operation of this operation, as shown in the connection portion of the two-stage feed pipe 53 and the riser pipe portion 60 of the present invention, the two-stage dewatering hole 55 is shown as shown. There is an end portion B formed. Therefore, while passing through the end portion (B), the contaminants A are once again dehydrated and stored in the storage hopper 70.

In more detail, the operation of this operation, when the compression force of the hydraulic cylinder 52 pushes the contaminant A in the direction of the riser tube 60, the condensate that accumulates in the vertical tube 61 of the riser tube 60 (A) presses down the force by that weight. At this time, the hydraulic cylinder 52 presses the strongly input of the contaminant A, which is strongly input using the shaft 21, toward the upward pipe part 60, and the weight of the contaminant A stored in the vertical pipe 61 and the piston 56. The pressing force of the contaminant A, which is pressurized by), faces each other. This is the effect of the dehydration by squeezing the contaminant (A) in which the conflict in the direction of the force is injected. At the end portion B of the two-stage transfer pipe 53, a plurality of two-stage dehydration holes 55 are formed, so that water is easily dehydrated.

Then, the contaminants (A) pushed through the vertical tube (61) to the horizontal tube (62) are dropped to the end and collected into the storage hopper 70, stored for a predetermined period of time and then disposed of.

The present invention is to squeeze the contaminants (A) newly subjected to the first dehydration process newly introduced due to the weight of the contaminants (A) accumulated in the vertical pipe 61 to be completely dehydrated. In addition, the dehydration method also uses the pressure of the hydraulic cylinder 52 and the weight of the contaminant A which has already been dewatered to some extent, and also has the characteristics of being transported to the storage hopper without a separate transport device at the same time as the secondary dehydration. .

In addition, in the present invention, the tube discharge portion 42 of the transfer tube 43, the tapered surface 81 to reduce the inner diameter of the transfer tube 43 is formed at the end portion, the rotation of the transfer screw 46 is a contaminant ( A) is pressurized, and this pressurization is increased by a bottleneck of the tapered surface 81 to generate a function of weaving the moisture of the contaminant A. FIG. The present invention is to automatically carry out the entire process of the work that must be transported to the storage hopper 70, in principle, the contaminant (A). That is, both the conventional invention and the present invention have achieved this task. However, the present invention is characterized in that the dehydration of water as well as the soil or sand naturally filtered using a simple process of the conveyance and conveying the contaminants to the desired point with the power of secondary dehydration without a separate conveying device. The present invention is invented by combining the structure of a tube and the action of a force. In the preceding description, the first stage dehydrator 40 achieved dehydration and transfer by using the rotation of the transfer screw 46 and friction between the contaminant A. FIG. This embodiment takes the same purpose, but is intended to increase the effect somewhat.

That is, in forming the tube discharge portion 42, which is the end of the transfer tube 43, by taking a manner to reduce the inner diameter to increase the load applied to the contaminant (A). To reduce the inner diameter is to form a tapered surface on the inner circumferential surface as shown in Figure 5 traffic jam (= bottleneck) occurs naturally when the conveying screw 46 presses the contaminant (A), the transfer tube according to the action (43) refers to the one-stage dehydration hole (47) formed on the lower surface to allow more water to be discharged.

In addition, in the present invention, in order to further increase the above-described effect, the blade 82 portion of the transfer screw 46 is formed to be narrower toward the tapered surface 81, so that the contaminants A are further pressed while being transported. Squeeze the moisture to be discharged to the first stage dehydration hole (47). FIG. 5 shows two such embodiments, and in FIG. 5A, the blades 82 of the transfer screw 46 have the same spacing h1 and h2 (h1 = h2). FIG. 5B shows an embodiment in which the intervals h1 and h2 of the blades 82 become narrower (h1 < h2) toward the tube discharge part 42 side. In the embodiment of Fig. 5 (a), the air gap is transported under the same condition, and the water in the contaminant A is removed by using a bottleneck caused by the tapered surface 81 on the tube discharge part 42 side. Although the embodiment is dehydrated, Fig. 5B is an embodiment in which this effect is further enhanced. That is, the blades 82 of the gradually narrowing feed screw 46 will dehydrate water while primarily adding bottlenecks to the contaminants A, and the tapered surface 81 on the tube outlet 42 side will be dehydrated. The phenomenon will be further strengthened to increase the dehydration effect.

Next, as shown in Figures 6 and 7, the present invention utilizes the end portion (B) formed with a two-stage dehydration hole 55 of the two-stage transfer pipe 53, the bottleneck 85 to reduce the inner diameter Formed, it is characterized in that the contaminants (A) can be further pressurized while being transported.

In other words, the bottleneck is also applied to the two-stage dehydrator 50 to further advance the effect of dehydration. When the shaft 21 of the hydraulic cylinder 52 has a left-right interlocking motion, a bottleneck 85 is formed in the end portion B of the two-stage transfer pipe 53 to reduce the inner diameter as shown in FIG. Against the pressing force of 56). At this time, the weight of the plurality of contaminants (A) stacked in the vertical pipe (61) will also increase the effect, due to this action is discharged water to the two-stage dewatering hole 55 formed at the bottom of the end (B), shown Exit to the old exhaust pipe (27).
