When a uniaxial crusher is used as a crushing and sorting device, hard resins that are unsuitable for fermentation are simultaneously crushed, and when the object to be crushed is sorted by wind force, it is placed on the side of heavy objects such as kitchens that are suitable for fermentation. While hard resin pieces after crushing, which are unsuitable for fermentation, are mixed in, paper waste, which is suitable for fermentation, is mixed in the lightweight side such as vinyl chloride resin pieces for packaging, which is unsuitable for fermentation, and cannot be sorted well. ..

Further, in the crushing and sorting machine as disclosed in Patent Document 2, the wet paper pieces crushed by the crushing impeller are entangled with the opening of the sieving surface and are not sieved off, and eventually the opening is clogged and frequently cleaned. There was a problem that work was required.

An object of the present invention is to provide a cleaning device for a fermentation suitable material sorting apparatus capable of avoiding clogging of a sieve surface for selecting fermentation suitable materials such as paper waste from a fermentation raw material to be treated, in view of the above-mentioned prior art. There is a point to do.

In order to achieve the above-mentioned object, the first characteristic configuration of the cleaning device of the fermentation suitable material sorting device according to the present invention is that crushing blades are attached along the circumferential direction and the axial center direction of the rotating shaft installed in the horizontal posture. It is equipped with an impeller and a cylindrical drum that is arranged so as to cover the impeller and has a sieve surface formed on the peripheral wall. A cleaning device for a suitable fermentation material sorting device for sorting products, the sliding tool holder attached to the crushing blade in a posture in which the longitudinal direction is along the axial center, and the axial center with respect to the sliding tool holder. It is provided with a sliding tool having a base end portion that can be inserted and removed in the direction along the above, and the tip of the sliding tool is slid on the inner peripheral surface of the sieve surface in conjunction with the rotation of the crushing blade. The point is that it is configured to clean the sieve surface.

A long sliding tool can be inserted into or detached from the sliding tool holder along the axial direction of the rotation axis of the impeller into the sliding tool holder attached to the crushing blade. Maintenance of tools is extremely easy. Then, even when the fermentation suitable material crushed by the rotation of the impeller is entangled with the sieve surface, it is appropriately removed by the sliding tool sliding on the inner peripheral surface of the sieve surface.

The second feature configuration is that, in addition to the first feature configuration described above, the sliding tool holder is attached to the surface rearward in the rotational direction of the crushing blade.

Since the sliding tool holder is attached to the rear surface of the crushing blade in the rotation direction, in other words, the surface on the side in the counter-rotating direction, it is possible to avoid direct collision with the object to be sorted as the crushing blade rotates, and the sliding tool. Damage caused by collision of the holder and the sliding tool with the sorting object can be avoided.

In the third feature configuration, in addition to the first or second feature configuration described above, the sliding tool holder has a columnar cavity formed in the center thereof through which the base end portion of the sliding tool can be inserted. It is composed of a cylindrical body, and a slit is formed on the outer peripheral surface of the tubular body so that the tip end side of the sliding tool can be extended.

In a posture in which the tip end side of the sliding tool is extended through a slit formed on the outer peripheral surface of the tubular body constituting the sliding tool holder, the base end portion of the sliding tool is placed in the hollow portion of the tubular body. It can be inserted.

In the fourth feature configuration, in addition to the third feature configuration described above, the sliding tool holder is composed of a cylindrical body having a polygonal cross-sectional shape on the outer peripheral surface, and is formed on the outer peripheral surface of the tubular body. One surface is welded and fixed to the crushing blade, and the slit is formed on the other surface of the outer peripheral surface of the cylindrical body.

Since one surface of the outer peripheral surface of the tubular body having a polygonal cross-sectional shape is welded and fixed to the crushing blade, the sliding tool holder can be accurately attached to the crushing blade in a fixed posture and slide. The tip side of the tool will extend from the sliding tool holder accurately in a constant posture. Moreover, even if the object to be sorted, which is scattered without a cylindrical drum as the impeller rotates, collides with the sliding tool holder, it will be torn at the corners of the polygon, and the cross-sectional shape will be circular. It is possible to avoid adhesion and accumulation as compared with the case of a state.

In the fifth feature configuration, in addition to any of the first to fourth feature configurations described above, the sliding tool is a columnar portion constituting a base end portion in which a plurality of pair of insertion holes are formed in the longitudinal direction. It is provided with a body and a thread-like member inserted so as to straddle each of the pair of insertion holes.

The sliding tool is configured to include a columnar body and a thread-like member, and the thread-like member is inserted so as to straddle each of a plurality of pairs of insertion holes formed along the longitudinal direction of the columnar body, so that the thread-like member is worn. Can be easily replaced.

The sixth characteristic configuration is that, in addition to the fifth characteristic configuration described above, the columnar body is chamfered on one end side of the insertion hole.

When the columnar body is chamfered, a void is formed between the inner surface of the hollow portion formed when the columnar body is inserted into the hollow portion formed in the tubular body and the outer surface of the columnar body. When the columnar body into which the thread-like member is inserted is inserted into the cavity, the bent portion, which is the top of the thread-like member inserted so as to straddle each of the pair of insertion holes, becomes the inner wall of the cavity due to the presence of the void. It can be inserted without interference.

In addition to the fifth or sixth feature configuration described above, the seventh feature configuration is configured such that the outer surface of the columnar body and the inner surface of the cavity of the sliding tool holder are in contact with each other. The point is that the pressure received by the columnar body due to cleaning is received by the inner surface of the cavity portion of the sliding tool holder.

With the columnar body of the sliding tool inserted through the cavity of the sliding tool holder, the outer surface of the columnar body and the inner surface of the hollow part of the sliding tool holder come into contact with each other, and the columnar body constituting the sliding tool is formed by cleaning. The pressure that the body receives due to the collision with the object to be sorted is received on the inner surface of the cavity of the sliding tool holder. Therefore, it is not necessary to firmly fix the columnar body inserted into the sliding tool holder.

In the eighth feature configuration, in addition to any of the fifth to seventh feature configurations described above, a fixing pin for fixing the columnar body is inserted into at least one end of the sliding tool holder and the columnar body. It is at the point where the hole is formed.

With the columnar body inserted through the sliding tool holder, the columnar body is prevented from coming off and fixed by inserting the fixing pin into the insertion hole formed at one end of both the sliding tool holder and the columnar body.

The ninth characteristic configuration is that, in addition to the second characteristic configuration described above, the extending direction of the sliding tool with respect to the crushing blade is set in the range of 0 to 90 degrees.

When the extending direction of the sliding tool with respect to the crushing blade is in the range of 0 to 90 degrees, it becomes possible to perform good cleaning while avoiding early wear of the sliding tool.

As described above, according to the present invention, there is provided a cleaning device for a fermentation suitable material sorting apparatus capable of avoiding clogging of the sieve surface for sorting fermentation suitable materials such as paper waste from a fermentation raw material which is a material to be treated. Can now be done.

Explanatory drawing showing the cleaning posture of the cleaning device

Hereinafter, the cleaning device incorporated in the fermentation suitable material sorting device according to the present invention will be described with reference to the drawings.
FIG. 1A shows an outline of the fermentation suitable material sorting apparatus 1. The fermentation suitable material sorting device (hereinafter, also referred to as “crushing and sorting machine”) 1 includes a metal cylindrical drum 2 arranged on a gantry so that the axis P is in a horizontal posture (horizontal posture). It includes an impeller 4 installed inside the drum 2, a loading hopper 6 opened above one end side of the drum 2, and a discharge port 7 opened on the other end side of the drum 2.

A sieve surface 2A made of punching metal having a plurality of openings 2H having a diameter of about 50 mm is formed in a region of the outer periphery of the drum 2 below the shaft core P.

The impeller 4 is attached to a rotating shaft 3 that rotates around the axis P in a comb-teeth shape along the circumferential direction and the axial direction of the rotating shaft 3, and the extension length in the radial direction is the inner diameter of the drum 2. It is equipped with a plurality of crushing blades 5 made of slightly shorter metal. Although not shown, a motor for rotationally driving the impeller 4 is arranged on the side of the drum 2. A corrosion-resistant metal material is preferably used as the material constituting the drum 2 and the impeller 4.

As shown in FIG. 1 (b), the impeller 4 crushes the rotating shaft 3 via attachments 3A and 3B so that the crushing blades 5 are positioned in a cross shape on the top, bottom, left and right in the axial P direction view. The blade 5 is attached. The attachments 3A and 3B and each crushing blade 5 are swingably attached via a swinging shaft 5A, and a centrifugal force acts during rotation of the impeller 4 to maintain the radial posture of the crushing blade 5. Collides with the object to be processed. However, when a hard member such as metal is mixed in the object to be processed, the crushing blade 5 is configured to swing around the swing shaft 5A and retract to avoid damage. .. The swing mechanism provided in the crushing blade 5 is not essential. Since the crushing blade 5 is also a crushing blade that crushes the object to be processed by hitting it in this way, it will be referred to as a crushing blade 5 below.

A pair of screw conveyors 8 arranged in parallel along the bottom of the loading hopper 6 are provided. For example, a resin bag-like material such as vinyl chloride resin filled with general waste, which is an example of fermentation raw materials (waste and valuable resources) transported by a belt-type conveyor mechanism, is dropped and supplied to the input hopper 6 from above. Then, in the process of being conveyed by the screw conveyor 8, a part of the bag is broken and the contents are exposed and supplied to the crushing and sorting space in the drum 2. Although not shown, a motor for rotationally driving the screw conveyor 8 is arranged on the side wall of the loading hopper 6.

The general waste supplied to the inside of the drum 2 which is the crushing and sorting space via the screw conveyor 8 includes fermentation in addition to organic waste such as kitchen waste and organic waste such as paper which are suitable for fermentation. It contains miscellaneous waste such as glass, resin, ceramic pieces, and metal pieces such as pots, which are unsuitable.

As the impeller 4 rotates, such general waste collides with a plurality of crushing blades 5 and is shear-crushed or impact-crushed while being conveyed to the discharge port 7 side along the axis P. Fermentation suitable material falls from the opening 2H of the sieve surface 2A, is collected by a conveyor mechanism installed below the sieve surface 2A, and is supplied to the methane fermentation apparatus.

On the other hand, the broken sheet-shaped resin, metal, and other unsuitable substances for fermentation are transported to the downstream side without being easily broken even if they collide with the crushing blade 5, and are discharged to the most downstream side of the rotating shaft 3. It is scraped up by the blade 9 and discharged from the discharge port 7 to the outside of the drum 2.

Paper, which is suitable for fermentation, is very light and stiff like a sheet of resin, so it is not easily broken even if it collides with the crushing blade 5, and is discharged from the discharge port 7 together with the unsuitable material for fermentation. The percentage tends to be high.

Even if sorting using a wind power sorting mechanism is adopted instead of sorting by the sieving mechanism 2A, paper is lighter than suitable fermentation products such as kitchen shavings like sheet-shaped resin, so it is suitable for fermentation. There is a high tendency to be sorted.

Therefore, it is not easy to sort and collect papers mixed in general waste as suitable for fermentation. Therefore, as shown below, a method of efficiently selecting papers as suitable for fermentation by humidifying them is adopted.

As shown in FIG. 2, general waste filled in a resin bag is put into a bag breaking machine to break the bag, and the broken object to be processed is put into the above-mentioned crushing sorter to perform shear crushing. Alternatively, a first crushing and sorting step of impact crushing and sorting and processing suitable for fermentation from the crushed object, a humidifying step of humidifying the residue from which the suitable fermentation is selected in the first crushing and sorting step, and humidification in the humidifying step. The resulting residue is further put into a crushing and sorting machine and subjected to shear crushing or impact crushing to sort out suitable fermentation products. By processing in the procedure of the second crushing and sorting process, papers suitable for fermentation can be efficiently recovered. do.

In the first crushing and sorting step, general waste is shear crushed or impact crushed, and fermentation-appropriate products are sorted from the crushed objects to be treated. Papers, which are relatively lighter than kitchen debris, are not sufficiently crushed and are not sorted as suitable for fermentation in the first crushing and sorting step, and are contained in the residue side which is unsuitable for fermentation.

However, the paper contained in the residue humidified in the humidification step absorbs moisture, increases its weight, and loses its waist, so that it can be easily crushed in the second crushing and sorting step, and is appropriately sorted as a suitable fermentation product. Will be done.

In the humidification step, the degree of moisture absorption of the paper can be adjusted to the extent that it can be easily crushed, so that the water content of the fermentation suitable material selected in the second crushing and sorting step can be kept low, so that the subsequent methane fermentation treatment can be performed. The fermentation process can be performed efficiently without causing an excessive increase in the amount of liquid.

It is preferable to have an inspection step for inspecting whether or not the residue discharged in the first crushing and sorting step contains suitable fermentation substances, and when the amount of suitable fermentation substances contained in the residue is very small. , Is transported to the unsuitable material processing device as it is. The inspection process can be visually determined by the operator either directly or based on the image taken by the image pickup device. Further, the photographed image may be image-processed to automatically determine the degree of content of the fermentation suitable substance. In particular, it is preferable to automatically determine whether or not paper is contained as a suitable fermentation product.

The humidification step is a step of spraying water on the residue through a spray nozzle, and the amount of spray is adjusted based on the state of contamination of the suitable fermentation substance contained in the residue after the suitable fermentation substance is selected in the first crushing and sorting step. It is preferable to include a spray amount adjusting process. The amount of spray from the spray nozzle is appropriately adjusted in the humidification step based on the content of the paper.

For example, it is equipped with a machine learning device that separates an image in which miscellaneous residues are taken based on the color and shape, and determines whether or not the paper is paper based on the shape and color of each separated area. However, when it is determined that the content of the paper is equal to or higher than the predetermined threshold, the process proceeds to the humidification step, and when it is determined that the content of the paper is less than the predetermined threshold, the paper is transported to the unsuitable material processing apparatus. Is preferable.

A spray amount adjusting mechanism can be configured by such a machine learning device. For example, the spray amount adjusting mechanism includes an input unit for inputting a captured image of the residue, a calculation unit for calculating the spray amount of water based on the captured image input to the input unit, and a water spray amount calculated by the calculation unit. It can be configured by a machine learning device provided with an output unit for outputting.

Specifically, the machine learning device can be configured with a neural network or the like, and the image in which miscellaneous residues in the preprocessing section are captured is separated into regions based on the color and shape, and papers are based on the shape and color of each region. It can be configured by a neural network that determines and outputs how much is contained and also outputs the amount of spray.

FIG. 3A shows a drum 2 serving as a crushing and sorting space, and an impeller 4 rotating inside the drum 2. The general waste charged into the drum 2 was hit by the crushing blade 5 of the rotating impeller 4, and suitable fermentation materials such as food waste and wet paper were crushed into small pieces and formed on the sieve surface 2A. It is shaken off from the opening 2H.

On the other hand, lightweight and stretchable vinyl chloride resin flakes such as garbage bags, bulky hard resin, and metal waste such as pots are not broken and are transported to the end of the drum 2 and discharged.

By the way, when a suitable fermentation substance is shaken off from the opening 2H formed on the sieve surface 2A, crushed wet pieces of paper or the like are likely to be entangled with the opening 2H, and if the entanglement is repeated, the opening 2A may be blocked. .. FIG. 3A shows such a state.

In preparation for such a case, as shown in FIG. 3B, the tip of the crushing blade 5 slides on the inner peripheral surface of the drum 2 to remove a piece of paper entwined with the opening 2H in conjunction with the rotation of the crushing blade 5. The cleaning device 10 is provided.

Hereinafter, the cleaning device 10 will be described in detail. In the following description, the crushing blade 5 will be described in a simple shape of a plate-shaped body and a support portion provided at the base end portion of the plate-shaped body. The swing shafts 5A and 5B are fitted into the support portion and are swingably supported by the attachments 3A and 3B (see FIG. 1 (b)).

As shown in FIGS. 4A and 4B, the cleaning device 10 includes a sliding tool holder 11 attached to the surface of the crushing blade 5 on the opposite rotation direction side in a posture in which the longitudinal direction is along the axis P. It is provided with a long sliding tool 12 configured to be removable with respect to the sliding tool holder 11 in a direction along the axis P (direction perpendicular to the paper surface). That is, as shown in FIGS. 3 and 8, the cleaning device 10 slides the tip of the sliding tool 12 on the inner peripheral surface of the sieve surface 2A in conjunction with the rotation of the crushing blade 5 to clean the sieve surface 2A. It is configured as follows.

In the present embodiment, since the sliding tool holder 11 is attached to the surface of the crushing blade 5 on the side opposite to the rotation direction, it directly collides with the nearest object to be sorted existing in the rotation direction as the crushing blade 5 rotates. This is avoided, and damage due to collision with the hard resin, metal, etc. contained in the objects to be sorted of the sliding tool holder 11 and the sliding tool 12 can be avoided. It is also possible to attach the sliding tool holder 11 to the surface of the crushing blade 5 on the rotation direction side.

The sliding tool holder 11 is formed of a cylindrical body having a regular hexagonal cross section in which a cylindrical hollow portion 11A through which the base end portion of the sliding tool 12 can be inserted is formed in the center portion, and the outer peripheral surface of the tubular body is formed. A slit 11B on which the tip end side of the sliding tool 12 can extend is formed in a part of the sliding tool 12 along the longitudinal direction.

The sliding tool 12 is inserted into the hollow portion 11A of the tubular body in a posture in which the tip end side of the sliding tool 12 is extended through a slit 11B formed on the outer peripheral surface of the tubular body constituting the sliding tool holder 11. Is inserted.

The sliding tool holder 11 may be formed of a cylindrical body having a polygonal cross-sectional shape, and may not be a regular hexagon. Since one surface of the outer peripheral surface of the tubular body having a polygonal cross-sectional shape is welded and fixed to the crushing blade 5, the sliding tool holder 11 can be accurately attached to the crushing blade 5 in a fixed posture. Further, the tip end side of the sliding tool 12 can be accurately extended from the sliding tool holder 11 in a constant posture.

Moreover, even when the sorting object scattered inside the cylindrical drum 2 collides with the sliding tool holder 11 as the impeller 4 rotates, it is torn at the corners of the polygon and slides. Compared with the case where the moving tool holder 11 is formed of a cylindrical body having a circular cross-sectional shape, it is possible to avoid depositing and depositing objects to be sorted. Further, the weight of the tip portion of the crushing blade 5 is increased, and the crushing ability is improved.

As shown in FIGS. 5 (a) to 5 (d) and FIGS. 6 (a) to 6 (c), a plurality of pairs of insertion holes 12H are formed in the longitudinal direction at predetermined intervals in the sliding tool 12 (the present embodiment). 4 sets), a columnar body 12A formed on a flat surface 12F by chamfering one end side of the insertion hole 12H, and four thread-like members 13 inserted so as to straddle each of the pair of insertion holes 12H from the flat surface 12F. It is equipped with.

As the thread-like member 13, a long body such as elastic natural rubber, synthetic rubber, or a resin material such as nylon can be adopted, and the long body is provided with a core member such as a metal wire to improve cleaning performance. , The life can be secured. The thread-like member 13 is set to a length such that at least the tip end side slides on the sieve surface 2A formed on the drum 2.

Each peripheral surface is shaped so that the outer surface of the columnar body 12A and the inner surface of the hollow portion 11A of the sliding tool holder 11 come into contact with each other, and the pressure received by the columnar body 12A during cleaning is applied to the hollow portion 11A of the sliding tool holder 11. It is configured to be received on the inner surface of. In the present embodiment, the outer surface of the columnar body 12A and the inner surface of the cavity 11A are formed in a cylindrical shape, but may be formed in a prismatic shape.

With the columnar body 12A of the sliding tool 12 inserted through the cavity 11A of the sliding tool holder 11, the outer surface of the columnar body 12A and the inner surface of the hollow portion 11A of the sliding tool holder 11 come into contact with each other, and the cleaning is performed. The pressure that the columnar body 12A constituting the sliding tool 12 receives due to the collision with the object to be sorted is received on the inner surface of the cavity 11A of the sliding tool holder 11. Therefore, it is not necessary to firmly fix the columnar body 12A inserted into the sliding tool holder 11.

As shown in FIGS. 4 (c) and 4 (d), insertion holes 11C and 12C of fixing pins 14 for fixing the columnar body 12A are formed at both ends of the sliding tool holder 11 and the columnar body 12A, and the insertion holes 11C, The fixing pin 14 is inserted through the 12C. The insertion holes 11C and 12C are preferably formed at both ends of the sliding tool holder 11 and the columnar body 12A in order to ensure safety, but may be formed at one end.

With the columnar body 12A inserted through the sliding tool holder 11, the fixing pin 14 is inserted into the insertion holes 11C and 12C formed in both the sliding tool holder 11 and the columnar body 12A, and the end portion is bent. The columnar body 12A is fixed to prevent it from coming off.

At this time, the space formed between the flat surface 12F formed in the columnar body 12A and the hollow portion formed in the sliding tool holder 11 is a space for accommodating the bent portion of the filamentous member 13 inserted into the insertion hole 12H. It becomes.

In this embodiment, the insertion holes 11C and 12C are formed at both ends, and the fixing pin 14 can be inserted and removed from either end, but can be inserted and removed only from one end. In this case, the insertion holes 11C and 12C need only be formed at one end. However, for safety, it is necessary to confirm the mounting of the fixing pin 14 without fail.

The extension direction of the sliding tool 12 with respect to the surface of the crushing blade 5 is preferably set in the range of 0 to 90 degrees, more preferably set in the range of 10 to 50 degrees, and 20 degrees. It is even more preferable that the temperature is set in the range of 40 degrees to 40 degrees. When the extending direction of the sliding tool is in the range of 0 to 90 degrees with respect to the surface of the crushing blade 5, it becomes possible to perform good cleaning while avoiding early wear of the sliding tool 12. If it is less than 0 degrees, the wear becomes remarkable, and if it is larger than 90 degrees, the cleaning ability is lowered. In the present embodiment, the sliding tool holder 11 having a regular hexagonal cross section is set to 30 degrees, which is equal to the angle from the welding surface to the crushing blade 5 to the forming surface of the slit 11B.

FIG. 7A is a view of the crushing blade 5 viewed from the counter-rotating direction, showing a state in which the sliding tool 12 is removed and only the sliding tool holder 11 is attached to the crushing blade 5.
