Description

  The present invention relates to a rotary type sorter capable of suitably separating and treating at a dismantling site a mixture of wall soil, rope, bamboo, tiles, timber, gravel and other wastes generated by dismantling a house. It is a thing.

  Dismantling a house generates a mixture of wall soil, rope, bamboo, tile, wood, gravel and other various wastes, but such a mixture is dismantled with soil, wood fragments, debris etc. If you take it out, it will become an industrial waste, and the disposal process after that will be expensive and not economical. Therefore, when the mixed materials are separated according to the material at the dismantling site, they become recyclable wastes and separated wastes and are processed by public agencies, which facilitates waste disposal.

  In general, various sieving devices are used to separate out different sizes of inclusions. For example, fixed sieves, movable rod sieves, rotary sieves, vibrating sieves, rocking sieves and the like are known, and in the case of a mixture containing various materials generated at the dismantling site, the so-called trommel type. Type classifiers are widely used. This rotary type sorting machine has a rotatable cylindrical rotary weir, and the wall surface is provided with a mesh having holes or a rod-like member having a slit formed with a gap to provide a gap serving as a sieve. It is The mixture to be separated is introduced into the rotary kiln through the opening at one end of the rotary kiln, and is sent to the opening at the other end by the rotation of the rotary kiln, during which the rotary kiln is rotated. Accompanied by moving up and down many times from the top to the bottom, and from the bottom to the top, it is crushed and crushed, and the finely divided pieces pass through the above-mentioned gap of the rotary kiln and fall to the outside, to the lower part of the rotary kiln. It will be collected in the put-in box. Large ones are sent to the opening on the other end side, collected when falling from the top of the inner surface of the rotary kiln by a chute or conveyor inserted into the rotary kiln from the opening, taken out to the outside of the rotary kiln and separated Ru.

  As described above, since the trommel-type sorter is configured to allow the small pieces to fall naturally from the gaps such as the holes and slits provided on the wall surface of the rotary kiln, the inclusions may be attached to the periphery of the gaps, or large ones. May cause clogging. If clogging occurs, the gap is clogged and the efficiency decreases, so it is necessary to stop the rotation of the rotary rod and take out the clogged material from the gap. In order to prevent such a situation, various devices are known in which the gap formed by the slits is enlarged with the rotation of the rotary wedge to remove the clogging (see, for example, Patent Document 1).

  The device described in Patent Document 1 is a drum in which both ends of a sieve rod (bar-like member) forming a slit-like sieve (a gap) are inserted into a radially elongated slot provided in a movable end plate. To make the gap between adjacent sieve bars widen as the drum moves and the sieve rods move in the radial direction so that the clogged material falls downward by its own weight. Configured. However, in such a device, only the clogged material is released by the action of the natural fall due to its own weight, so if clogged material that is firmly sandwiched between the sieve rods is generated, it is easily dropped and removed What can not be left remains. Therefore, in order not to cause clogging, the gap by the slit can not be made very narrow.

JP, 2007-130515, A (claim 1, paragraph 0015, 0027, FIG. 3)

  The problem to be solved by the present invention is to provide a rotary type sorter capable of positively pushing out a clogged material that has entered into a gap of the rotary rod when the rotary rod is rotated in the trommel type separator. It is.

  According to the present invention, between the fixed plate forming a sieve in parallel in the circumferential direction by opening the passage gap in the radial direction of the rotary cylinder so as to form the rotary weir, and between the fixed plate in the passage gap There is provided a rotary type sorting machine characterized by having a protrusion provided with a gap and moving the protrusion radially along the fixed plate within the passage gap when the rotary rod is driven. , The above problem is solved.

  In the present invention, there is provided a rotary type sorting machine in which the protrusion is a sliding plate which is forcedly or positively moved along the fixed plate, and as the protrusion, the rotary is rotated adjacent to the fixed plate. A body-mounted rotary sorter is provided.

  The present invention is configured as described above, fixing a fixed plate forming sieves in parallel in the circumferential direction by opening a passage gap in the radial direction of the rotary cylinder so as to form the rotary weir, within this passage gap A gap is provided between the fixed plate and the protruding member, and when the rotary rod is driven, the protruding member is moved in the radial direction in the passage gap. When the protrusion moves radially between the fixing plates, the tip of the protrusion is pushed out, and clogging is eliminated. Therefore, there is no risk of clogging even if the gap in which the strip falls is made narrower than the conventional one.

  If the above-mentioned projection is constituted by a sliding plate which slides in the radial direction in the passage gap, the passage gap is expanded when the sliding plate is receded below the tip of the fixed plate, and the fined fine The piece can be dropped downward without any problem. When the sliding plate moves in the direction of the tip of the fixing plate, the clogging between the fixing plates can be pushed out at the leading end of the sliding plate as the sliding plate advances. Since the sliding plate can be controlled to move at a suitable position during rotation of the rotary wedge, even the fine pieces caught in the gap with the fixed plate can be easily moved inward of the rotary wedge. It can be pushed out and recovered reliably. Further, when the protrusion is formed as a rotating body that rotates in the passage gap, the plane of the fixing plate can be swept and scraped by constantly rotating the rotating body along the side surface of the fixing plate. It can eliminate clogging.

The rotary cylinder 2 has an annular rail 5 on the outer peripheral surface, the rail 5 is mounted on a wheel 6, and the wheel 6 is rotatably held by a pillow 8 fixed to a base frame 7. Further, a sprocket 9 is provided on the outer periphery of the rotary cylinder 2, and the sprocket 9 and a drive sprocket connected to a motor (not shown) are connected by a chain (not shown) and rotationally driven. Contaminants to be separated are supplied into the rotary kiln from one opening side of the rotary kiln 1, screened with a sieve, and large ones not screened are from the other opening side of the rotary kiln 1 Exhausted. Under the rotary rod 1, there is provided a receiving box 10 for collecting the small pieces dropped from the passing gap, and on the side of the rotary cylinder, an end plate 4 located on both sides of the rotary rod 1 and having an opening formed. The side frame 11 having the

  In the passage gap A formed by the fixed plate 3, the protrusion 12 is inserted with a space where the small plate can drop from the fixed plate 3. The projection 12 is rotatably supported so as to rotate with the fixed plate 3 when the rotary rod 1 is rotated, and is forcibly or positively moved radially along the fixed plate 3 within the passage gap. To be held by the control means.

The protrusions can be formed into a circular cross-section, an oval cross-section, or other various shapes, but in the embodiment shown in FIGS. 1 to 4, a fine strip is formed between the fixed plate and the passing gap. There is composed of the sliding plate 13 formed with a rectangular cross-section of the sheet metal material having a width capable of producing a passable minute gap, which movement is controlled by the control means fitted to an end. A groove extending in the radial direction of the rotary rod 1 can also be provided on the surface of the flat portion of the sliding plate 13 facing the fixed plate 3 (not shown).

The control means can be configured in various ways. In the embodiment shown in FIGS. 1 to 4, a guide groove 14 having a substantially U-shaped cross section having a width that receives the upper and lower ends of the sliding plate 13 on the inner side of the side frame 11, ie, the rotary rod 1 side. Forming a guide 15 having both ends, and restricting the movement of the sliding plate 13 in the radial direction of the rotary rod 1 by fitting the both ends to the guide 15 and preventing the sliding plate 13 from coming out in the longitudinal direction of the rotary rod It is like that. Then, the entire shape of the guide 15 is different from the rotation locus of the rotary rod when the rotary rod is circular, elliptical, curved annular body, meandering annular body or other rotary rod which is eccentric from the center of the circular shape of the rotary cylinder 2 By forming it in an annular shape, in the embodiment shown in FIG. 1, by forming it in an elliptical shape, the amount of movement of the sliding plate in the radial direction during rotation of the rotary rod is controlled. An appropriate roller may be provided at both ends of the sliding plate 13 to roll the inner surface of the guide (not shown). According to the configuration, the sliding plate 13 in which both ends are slidably fitted to the inner surface of the guide 15 is forcibly moved inward and outward with respect to the center of the rotary rod 1 according to the shape of the guide 15 , Retracts or protrudes from the tip of the fixed plate 3 in the direction of the center of the rotary rod.

The control means shown in FIG. 5 comprises a guide provided on the side frame 11 with an annular outer ring 16 and an inner ring 17, and a sliding plate inserted in the holding gap 18 between the outer ring 16 and the inner ring 17. Upper and lower widths of both end portions 19 of 13 are formed narrower than the above-mentioned holding interval . With this configuration, when the rotation cage 1 is rotated, the sliding plate 13 is moved positively by the weight of the sliding plate itself in the holding interval 18, the rotation from the front end of the fixing plate 3 by the position of the rotary cage 1 cage The tip of the sliding plate 13 in the direction of the center of the head retracts or protrudes. Incidentally, the embodiment shown in FIG. 4 and the embodiment shown in FIG. 5 are appropriately combined to have a portion which is forcibly guided and moved by the guide groove and a portion which is positively moved by its own weight in the guide groove. It may be a guide.

Further, in the above embodiment as the guide portion by the guide 15, a guide 15 having a guide groove 14 of substantially U-shaped cross section is provided, so as to fitting engagement by inserting the upper and lower portions at both ends of the sliding plate 13 to the guide 15 However, the relative position may be changed to the opposing member side. For example, the annular guide plate 21 to form a substantially U-shaped receiving groove 20 that opens to the side, as shown in FIG. 6 the end portion of the sliding plate 13, which fitting engagement slidably this receiving groove 20 The guide 15 may be provided on the side frame 11 as control means. Then, the annular guide plate 21 is not a perfect circle, but is formed in a shape different from the rotation trajectory of the rotary weir, for example, a shape meandering in a wave shape in the circumferential direction. 13 movements can be controlled. FIG. 7 shows an example of meandering by the control means, where point a shows the position where the annular guide plate 21 is at the innermost (in the direction of the rotation center of the rotary rod), point c is at the outermost position, and point b is The annular guide plate 21 is bent and provided so as to be an intermediate portion thereof. The amount of displacement at this time is, for example, when the sliding plate moves in the outward direction of the fixed plate of 1.3 mm when moving from point a to point b with respect to the center of the rotary rod and moves from point b to c It moves in the outward direction of 0.7 mm and moves inward of the 0.7 mm fixed plate when moving from point c to point b, and moves inward by 1.3 mm further when moving from point b to point a Can be controlled. Such a meandering state may be provided by repeatedly projecting and retracting in the same manner throughout the entire annular guide plate, or may be formed in a meandering shape that randomly protrudes and retracts as appropriate.

  The above control means can force the slide plate 13 in the radial direction either forcibly or positively at any time during rotation of the rotary rod 1, but preferably, it is easy for the strip to drop at the lower portion of the rotary rod 1 It is good to be able to push out the clog at the top of the rotary rod. Specifically, as shown in FIG. 8, when the tip 22 of the sliding plate 13 is retracted from the tip 23 of the fixed plate 3 at the lower part of the rotary rod 1 to widen the passage gap and comes to the upper part of the rotary rod 1 As shown in FIG. 9, the sliding plate 13 is controlled to move in the direction of the tip 23 (lower part in the radial direction) of the fixed plate 3 so that the tip 22 protrudes. As described above, since the clogging object can be protruded by sliding the sliding plate 13 along the fixed plate 3, at what position of the rotary rod 1 the sliding plate 13 is moved Can be done as appropriate. In addition, as shown in FIG. 10, the entire sliding plate 13 is rotated so that the rear end 29 of the sliding plate 13 protrudes from the tip 23 of the fixed plate 3 at an appropriate position of the rotating rod, for example, as shown in FIG. If control is made to move inward of the ridge, the size of the opening B between the front end 23 of the fixed plate 3 and the rear end 29 of the sliding plate 13 can be changed as appropriate. Can correspond to the size of

  According to the above configuration, the sliding plate 13 is pushed and rotated by the fixed plate 3 when the rotary rod 1 is rotated, and simultaneously moves in the radial direction of the rotary rod 1 along the fixed plate 3 by the control means. The tip end of the sliding plate 13 can be brought into contact with the clogged material sandwiched between the two to be pushed out.

In the above embodiment, the protrusion 12 is constituted by the sliding plate 13 but may be constituted by a rotating member 24 which performs a planetary motion adjacent to the fixed plate 3. FIGS. 11 and 12 show such an embodiment, in which the rotating body 24 is provided between the fixed plates 3 forming the passage gap, and it is possible to form a gap between the fixed plates 3 and in which the strip falls. It is formed of an outer diameter round bar or a cylindrical cylindrical body. A bearing 26 rotatably supporting a rotating shaft 25 of the rotating body 24 is fixed to an end plate provided at the opening of the rotating cylinder , and a planetary gear 27 provided at an end of the rotating shaft 25 It engages with the internal gear 28 provided inside, whereby the rotating body 24 rotates by planetary motion adjacent to the fixed plate 3 when the rotary rod 1 rotates.

  According to the above configuration, when the rotary rod 1 is rotated, the rotary body 24 revolves and rotates automatically, and the small pieces fall through the gap with the fixed plate 3, and the clogging object sandwiched with the fixed plate 3 is the rotary body 24. As a result, it is scraped out from the tip of the fixed plate 3 and is projected into the rotary rod 1 to prevent clogging. In the meantime, wing pieces extending in the longitudinal direction may be formed in a projecting state on the outer periphery of the rotating body 24 so as to be more efficiently scraped (not shown).

  In the above embodiment, when the rotary wedge is formed to have a circular cross section and driven, it is configured to rotate 360 degrees, but when the rotary wedge is driven, the rotary wedge swings within a predetermined angle You may make it move (swing movement). In addition, the rotary rod may be formed into a cross-sectional fan shape and oscillated without being made circular in cross section. In the case of a rocking movement, the movement of the sliding plate as described above may be controlled by a guide having a guide portion which does not match the rocking trajectory of the rotary rod.

  In the above embodiment, the rotary crucible has a single-layer structure, but a rotary crucible having a smaller diameter may be provided inside the large-diameter rotary crucible to form a rotary crucible having a multilayer structure. FIGS. 13-15 is explanatory drawing which shows one Example of the rotary-type fractionator whose rotary kiln is 3 layer structure.

  The outer rotary cylinder 34 forming the outer rotary cylinder 30, the intermediate rotary cylinder 35 forming the intermediate rotary cylinder 31, and the inner rotary cylinder 36 forming the inner rotary cylinder 32 are formed with sieve mesh outside. Fixed plate 37, intermediate fixed plate 38, and inner fixed plate 39 are fixed in parallel at intervals in the circumferential direction, and between the fixed plates, outer slide plate 40, middle slide plate 41 And an inward sliding plate 42 is provided to move forcibly or positively in the radial direction of the rotary rod along each fixed plate. The distance between the inner fixed plates 39 of the inner rotary weir 32 is the largest, and the distance between the intermediate fixed plates 38 of the intermediate rotary weir 31 is narrower than that, and the distance between the outer fixed plates 37 of the outer rotary weir 30 is smaller Are formed so as to be narrower.

  The distance between the fixed plates is, for example, 23.7 mm between the inner fixed plate 39 and the inner sliding plate 42, 6.0 mm between the intermediate solid plate 38 and the intermediate sliding plate 41, and the outer The distance between the fixed plate 37 and the outer slide plate 40 is 1.0 mm. According to this configuration, among the inclusions introduced into the crucible from one opening of the inward rotary crucible 32, those having a particle diameter larger than 23.7 mm are allowed to pass through the sieve of the inward rotary crucible 32. It moves in the longitudinal direction and is discharged from the other opening to the outside of the inward rotary rod. Among the inclusions passing through the sieve of the inner rotary weir 32, the mixture having a particle diameter larger than 6.0 mm does not pass through the sieve of the intermediate rotary weir 31 from the other opening side of the intermediate rotary weir Of the inclusions which have been discharged and which further reach the outer rotary weir 30, those having a particle diameter larger than 1.0 mm are discharged from the other opening side of the outer rotary weir, and those having 1.0 mm or less, It can be collected in a receiving box provided below the rotary kiln, and as a result, it can be separated into four types of sizes. In the above-described sorting process, the clogged material sandwiched between the fixed plates is pushed out of the sieve by the outer sliding plate 40, the intermediate sliding plate 41 and the inner sliding plate 42, and the operation of the sorting machine Can be processed efficiently without stopping the
