Description

  The present invention relates to a traction apparatus for semi-carbonizing a litter containing horse dung and the like.

  Racehorses in horse racing belong to a stable managed by a trainer after being trained on a breeding ranch. Rice straw is mainly laid on the horses in the breeding ranch or stable, but the rice straw containing horse excreta (hereinafter referred to as “shrink”) is changed at intervals of about 1 to 2 days. This is because, due to the nature of a racehorse, cleaning is performed more frequently than when a horse for horse riding is bred, so that the physical condition of the horse can be fully managed. For example, in a medium-scale breeding ranch with about 200 racehorses, 5 tons of horse dung, etc. are exchanged per day.

  Horse dung etc. collected by exchange are mainly used as fertilizer. However, it takes about 3 to 5 months to ferment the accumulated horse droppings and use it as a fertilizer. For this reason, if horse dung and the like waiting to be processed are left unattended, they give off a terrible odor and may cause pollution. Then, as described in Patent Document 1, an invention for producing fertilizer and carbon products by drying and carbonizing livestock dung is also disclosed.

  Incineration of horse manure, etc. is also under consideration, but because it contains a lot of water (about 50%), the combustion efficiency is poor and the cost of fuel (propane gas, city gas, kerosene, heavy oil, etc.) is high. Not only that, the generation of carbon dioxide presents a serious problem in terms of environmental conservation.

  First, the structure of the torsion apparatus according to the present invention will be described in detail. FIG. 1 is a side cross-sectional view of the trellising apparatus. The torrefaction apparatus 100 is an apparatus that efficiently converts biomass energy by heating the litter 500 or the like without burning it to blow off moisture. The litter 500 is a rice straw mainly containing horse manure discharged continuously from the horse farm or the stables of racehorses, and may be converted into semi-carbides 501 to be used as biomass fuel or incinerated. It may be converted into ash 502 and used as a ash fertilizer for agricultural products. In addition, the converted biomass fuel may be reused as a heat source for the traction apparatus 100. The torrefaction apparatus 100 includes a rotary kiln 200, a sorting unit 300, and a combustion table 400.

  1 will be mainly described with reference to FIGS. FIG. 2 is a front view of the rotary kiln of the traction apparatus. FIG. 3 is a rear view of the rotary kiln of the traction apparatus. FIG. 4 is a cross-sectional view taken along the line AA of the rotary kiln of the traction apparatus. FIG. 5 is a view showing the inside of the rotary kiln of the trellising apparatus. 6 and 7 are BB cross-sectional views of the rotary kiln of the trellising apparatus.

  The rotary kiln 200 is a rotary processing furnace that semi-carbonizes the litter 500 to generate a semi-carbide 501. Semi-carbonization is to completely carbonize by heating at a relatively low temperature when roasting in an oxygen-free state. The rotary kiln 200 is shaped like a cylinder, but is tilted at an angle of about 7 to 15 degrees with respect to the horizontal, and is installed so as to slide down little by little when the litter 500 is put inside. The rotary kiln 200 is heated at a relatively low temperature of about 150 to 250 degrees and is rotated at a speed of about 0.5 to 2 times per minute. The rotation speed is arbitrary and may be adjusted appropriately. For example, when the angle of the rotary kiln 200 is about 8.5 degrees, the litter 500 moves about 65 mm per rotation. The configuration of the rotary kiln 200 includes a cylindrical body 220 and an exterior body 210, and a plurality of partition plates 226 and a plurality of hook plates 227 are provided inside the cylindrical body 220.

  The cylindrical body 220 is a container having a hollow inside, and the litter 500 is placed therein. A charging port 221 is provided on the inclined high side, and a dropping port 222 is provided on the low side. For example, as shown in FIG. 2, one inlet 221 is opened on the upper bottom surface of the cylindrical body 220, and as shown in FIG. 1, a drop port 222 is opened on the peripheral surface on the lower bottom surface side. If the side on which the insertion port 221 is provided is the front side and the side on which the drop port 222 is provided is the back side, the cylindrical body 220 is inclined from the front side to the back side, so the litter 500 moves in that direction. I will do it.

  Further, a material having high thermal conductivity such as metal is used for the peripheral surface of the cylindrical body 220, and the litter 500 on the inner peripheral side is heated by raising the temperature on the outer peripheral side. The cylindrical body 220 has a rotation shaft 223 that passes vertically through the center of the lower bottom surface, and is rotatably supported. The rotating shaft 223 is rotated by the power of the drive motor 224. For example, the power of the drive motor 224 may be transmitted to the rotating shaft 223 via a belt 225 as shown in FIG. When the cylindrical body 220 is rotated, the spreader 500 moves accordingly.

  As shown in FIG. 2, the upper bottom surface side of the cylindrical body 220 is supported by the receiving roller 230 so as to be in contact with the peripheral surface of the cylindrical body 220. The receiving rollers 230 may be provided at two places on the lower left and right sides of the cylindrical body 220. The receiving roller 230 is in contact with the cylindrical body 220 and rotates around the shaft 233 as the cylindrical body 220 rotates, and the outer ring having a larger diameter than the inner ring 232 in front of the inner ring 232 so as to hold the cylindrical body 220. 231 and is attached to the frame 240 by a support plate 234.

  The exterior body 210 is a frame plate that covers the outside of the cylindrical body 220. As shown in FIG. 4, an air layer 212 for passage of the combustion gas 511 is ensured between the outer peripheral side of the cylindrical body 220 and the inside of the exterior body 210. The combustion gas 511 is a gas generated when the fuel is combusted. The combustion gas 511 is supplied from an air supply port 213 (see FIG. 1) provided on the lower surface or the like of the exterior body 210 and filled in the air layer 212. The gas is exhausted from the exhaust port 251 through a chimney 250 provided on the upper surface of 210.

  The heat of the combustion gas 511 is conducted to the cylindrical body 220, but it is conducted to the exterior body 210 so that the efficiency of conduction to the cylindrical body 220 does not decrease, so that a heat insulating material is provided inside the exterior body 210. 211 is provided to cover the air layer 212. In addition, since it becomes difficult to conduct heat to the exterior body 210 by the heat insulating material 211, the exterior body 210 is suppressed from being heated by the combustion gas 511.

  A plurality of partition plates 226 and a plurality of hook plates 227 are detachably attached to the cylindrical body 220 along the inner periphery. The partition plate 226 is an annular plate that protrudes along the inner periphery of the cylindrical body 220, and may be formed in an arc shape such as a semi-ring without a part of the ring. A plurality of the partition plates 226 are provided at predetermined intervals from the near side to the far side of the cylindrical body 220. Of the plurality of semi-annular partition plates 226, the odd number from the near side is one side of the inner periphery of the cylindrical body 220, and the even number from the near side is the other side of the inner periphery of the cylindrical body 220. The partition plates 226 may be provided alternately from the front side to the back side of the body 220. The partition plate 226 is used to temporarily receive the litter 500 put into the cylindrical body 220, but the width of the ring of the partition plate 226 is arbitrary.

  The hook plate 227 is a plate that protrudes from the inner periphery of the cylindrical body 220 from the near side to the back side of the cylindrical body 220, and the partition plate 226 has a shaft further than the width that protrudes from the inner periphery of the cylindrical body 220. It is bent in the rotational direction of the cylindrical body 220 at a position protruding toward it. In addition, what is necessary is just to bend in the range of about 30-90 degree | times. A plurality of the catch plates 227 are provided at a predetermined interval such as a position at which the cylindrical body 220 is equally divided when the cross section of the cylindrical body 220 is viewed. For example, four hook plates 227 may be provided every 90 degrees. The hooking plate 227 is used to lift the litter 500 from the lower part of the cylindrical body 220 in the rotation direction, but the length of the bent front end is arbitrary.

  The partition plate 226 and the hook plate 227 are formed of metal or the like in the same manner as the cylindrical body 220, and a cylindrical frame is formed by connecting the partition plate 226 and the hook plate 227 with an adhesive or welding. In addition, it may be inserted into the cylindrical body 220. Cylindrical frames having different numbers and widths of partition plates 226 or hook plates 227 are prepared for cases where the condition and conditions of the bedding 500 are different or when processing things other than the bedding 500. Depending on the application, the cylindrical frame may be replaced. For example, as shown in FIG. 5, the partition plate 226 has alternating portions provided between the hook plate 227 and the hook plate 227 adjacent thereto along the inner periphery of the cylindrical body 220. It is also possible to use a structure in which portions provided in an arc shape and portions not provided are alternately provided from the front side to the back side of the cylindrical body 220.

  The cylindrical body 220 rotates in a state where the peripheral surface is heated by the high-temperature air of the air layer 212, and the litter 500 introduced into the inside through the insertion port 221 of the cylindrical body 220 is heated while the cylindrical body 220 is heated. Although it slides down from the near side to the back side due to the inclination, the time for heating is increased by stopping by the partition plate 226 and limiting the sliding down. Further, with the rotation of the cylindrical body 220, the spread sheet 500 stopped by the partition plate 226 is placed on the catch plate 227 and carried upward. In the lower part of the cylindrical body 220, the spreader 500 is restricted from advancing to the back side by the partition plate 226. The restriction of the partition plate 226 is eliminated. Then, the spreader 500 slides down to the back side, and further slides down from the front end portion of the hook plate 227 to return to the lower part of the cylindrical body 220. At this time, the partition plate 226 is overcome by one, and the next partition plate Move to 226. Drying is promoted because the litter 500 falls apart when falling from the upper part to the lower part. By repeating this, the litter 500 is heated while being stirred in the cylindrical body 220 and gradually becomes a semi-carbide 501 while proceeding from the near side to the far side of the cylindrical body 220. Since the bedding 500 contains moisture, the moisture evaporates by heating and the water vapor is discharged from the inlet 221, so that the inside of the cylindrical body 220 is maintained in a state where oxygen is difficult to be supplied.

  The cylindrical body 220 is not directly heated by the flame 510 but is heated at a relatively low temperature by filling the air layer 212 with the combustion gas 511, so that the litter 500 advances to the back side of the cylindrical body 220. It is gradually roasted and changed to a semi-carbide 501. On the back side of the cylindrical body 220, the exterior body 210 is not covered, and a drop opening 222 is opened in a part of the peripheral surface of the cylindrical body 220 as shown in FIG. 6. As shown in FIG. 7, the semi-carbide 501 is discharged from the dropping port 222 when the dropping port 222 comes to the lower side by the rotation of the cylindrical body 220. For example, two falling openings 222 may be provided so that the semi-carbide 501 is discharged every time the cylindrical body 220 makes a half turn.

  The rotary kiln 200 is supported in a state having a predetermined height by the frame 240 in order to dispose the sorting means 300 and the combustion table 400 below the rotary kiln 200. The frame 240 is a combination of a support frame 241 on which the rotary kiln 200 is placed and a leg frame 242 that supports at least four sides of the rotary kiln 200 at a predetermined height. The rotary kiln 200 may be movable by attaching a caster 243 to the lower end of the leg frame 242.

  The separating means 300 arranged below the rotary kiln 200 receives the semi-carbides 501 discharged from the dropping port 222 of the rotary kiln 200 and conveys them separately for each subsequent processing destination. FIG. 8 is a perspective view of the sorting means of the trellising apparatus. The sorting unit 300 includes a hopper 310, a delivery plate 340, and a delivery pipe 320, and a feed screw 330 inside the delivery pipe 320.

  The hopper 310 receives the semi-carbide 501 of the spreader 500 dropped from the dropping port 222 of the rotary kiln 200 at the receiving port 311. As shown in FIG. 8, the hopper 310 is provided with a delivery plate 340 by cutting out the installation groove 313. The delivery plate 340 is a plate inclined like a slide, and is inserted into the installation groove 313 so that the upper end side comes to the vicinity of the center of the hopper 310. Part of the falling semi-carbide 501 is received by the delivery plate 340 and the rest is dropped to the bottom of the hopper 310. In addition, the ratio which sorts by changing the degree which inserts the sending board 340 is adjusted. For example, about 70 to 80% of the half carbide 501 may be received by the delivery plate 340, and about 30 to 20% of the half carbide 501 may be received by the hopper 310.

  A part of the half carbide 501 received by the delivery plate 340 is accumulated and stored for fuel, and the remaining half carbide 501 received by the hopper 310 is sent to the combustion table 400 via the delivery pipe 320. A feed screw 330 is disposed laterally on the bottom of the hopper 310. The feed screw 330 extends inside the delivery pipe 320, and the remainder of the semi-carbide 501 is conveyed by the feed screw 330 and discharged from the discharge port 321 of the delivery pipe 320.

  The feed screw 330 is a screw in which a plate protruding around a rod-shaped rotating shaft 331 made of metal or the like is spirally wound, and in a groove formed between the screw plates by rotating the rotating shaft 331. The sandwiched half carbide 501 is moved in the axial direction. The rotating shaft 331 may be rotated by transmitting the power generated by the drive motor 332 through the belt 333.

  In order for the feed screw 330 to pass through the feed pipe 320, the semi-carbide 501 needs to enter the groove of the feed screw 330. Since the semi-carbide 501 is mainly rice straw, it does not enter the delivery pipe 320 if a large number of elongated ones are included. Therefore, as shown in FIG. 1, the semi-carbide 501 can easily enter by rounding and curving the corners of the connecting portion 312 connecting the hopper 310 and the delivery pipe 320. In addition, a pressing mechanism for forcibly pressing the semi-carbide 501 into a groove with a lid shape may be provided at a position before entering the delivery pipe 320. If the feed screw 330 is kept pressed, the semi-carbide 501 coming in later will not enter, so the hold-down mechanism may be opened and closed with a spring or the like.

  The combustion table 400 disposed in front of the sorting means 300 incinerates the semi-carbide 501 as fuel, and the combustion gas 511 generated at that time is sent to the rotary kiln 200 and used to heat the rotary kiln 200. The incinerated ash 502 remaining on the combustion table 400 is recovered and stored for fertilizer. FIG. 9 is a perspective view of a combustion table of the trellising apparatus. The combustion table 400 includes a combustion table 410, a blower 420, and an ash receiving box 430.

  The combustion table 410 is a columnar table, and can be rotated by placing a semi-carbide 501 thereon. In order to burn the semicarbide 501 placed thereon, a flame 510 may be generated on the combustion table 410 by storing a heat source inside the combustion table 410. Since the semi-carbide 501 is annularly mounted on the side of the combustion table 410 close to the circumference, when being discharged from the discharge port 321 of the delivery pipe 320, it is dropped to the end side of the combustion table 410 and the combustion table 410 is rotated. .

  The combustion table 410 may be rotated by a drive motor 412 with a rotating shaft 411 passing vertically through the center of the combustion table 410. Since the semi-carbide 501 is mounted on the combustion table 410 in a ring shape, the flame 510 is generated in a state where the flame is expanded as compared with the case where combustion is performed at the center of the combustion table 410. In order to prevent the flame 510 from spreading too far outside the combustion table 410 and to prevent the combustion gas 511 generated by the combustion of the semi-carbide 501 from leaking to the outside, a cover 401 is placed on the combustion table 410, Then, the combustion gas 511 is sent out to the air supply port 213 of the rotary kiln 200 and flows into the air layer 212. In order to efficiently flow the combustion gas 511 upward, a blower 420 that generates wind from the bottom to the top is disposed below the combustion table 410.

  As the combustion of the semi-carbides 501 proceeds, the incineration ash 502 remaining after the combustion gradually increases and accumulates in the center of the combustion table 410 or falls outward. What has fallen outside the combustion table 410 is temporarily received in the ash receiving box 430. When the incinerated ash 502 is accumulated in the ash receiving box 430, the ash receiving box 430 is moved to the ash receiving 431 by providing an openable opening window in the ash receiving box 430, and stored as fertilizer. For the incineration ash 502 remaining on the combustion table 410 without falling outside the ash receiving box 430, a wiper or the like is provided, and the incineration ash 502 is moved to the ash receiving box 430 while rotating the combustion table 410. Just drop it. The wiper may be movable, such as automatically rotating, and the wiper may remove the incineration ash 502 at a predetermined interval.

  The combustion table 400 is also supported by a frame such as a leg and can be moved by wheels provided on the lower surface of the frame. That is, it can be separated from the rotary kiln 200 and the separating means 300 and used as a single heat source. Alternatively, external energy such as another boiler may be prepared and the combustion gas 511 may be sent to the rotary kiln 200.

  In this way, the litter 500 collected from the racehorse breeding ranch or stable can be semi-carbonized efficiently. The semi-carbide 501 can be used as biomass fuel, and by burning the semi-carbide 501, it can be used as a heat source when semi-carbonizing another litter 500, and the remaining incineration Ash 502 can be used as a fertilizer.

  Next, the reflection processing method according to the present invention will be described in detail. FIG. 10 is a flowchart showing the flow of the processing method by the trellising apparatus. The processing method 600 includes a material collection 610 step, a material cutting 620 step, a material input 630 step, a refracting 640 step, a fuel recovery 650 step, a semi-carbide delivery 660 step, and a semi-carbide. A combustion 670 step, a combustion gas delivery 680 step, and an incineration ash recovery 690 step.

  In the material collecting step 610, the litter 500 is collected as a material from the breeding ranch or stable of the racehorse. The litter 500 that has just been collected has many rice straws having a length of about 300 to 500 mm, so that it may be too long to be processed by the trephing apparatus 100.

  In the material cutting step 620, the litter 500 collected by the material collection 610 is cut to an appropriate length by a cutting machine. The length is preferably about 20 to 50 mm.

  In the material charging step 630, the litter 500 whose length is adjusted by the material cutting 620 is input to the rotary kiln 200.

  In the step of the refracting 640, the litter 500 charged by the material charging 630 is processed by the rotary kiln 200 to generate a semi-carbide 501. The rotary kiln 200 is tilted to about 8 to 10 degrees, and is gradually advanced to the back so as not to cause clogging without causing natural fall. Moreover, since it is difficult to supply oxygen, semi-carbonization proceeds without spontaneous ignition. The semi-carbide 501 is divided into two, and a part of the semi-carbide 501 is processed in the process of the fuel recovery 650, and the rest of the semi-carbide 501 is processed in the process of the semi-carbide delivery 660. The water content of the semi-carbide 501 to be used as fuel is preferably about 8 to 10%, and the rotational speed and heating temperature of the rotary kiln 200 are adjusted according to the water content of the litter 500.

  In the step of fuel recovery 650, a part (for example, about 70 to 80%) of the semi-carbides 501 processed by the treffaction 640 is separated for use as biomass fuel.

  The process of the semi-carbide delivery 660 sends the remainder (for example, about 20 to 30%) of the semi-carbide 501 processed by the traction 640, which is divided by the separating means, to the combustion table 400.

  The semi-carbide combustion 670 process burns the remainder of the semi-carbide 501 sent in the semi-carbide delivery 660. The combustion gas 511 generated at the time of combustion is processed in the process of combustion gas delivery 680, and the incinerated ash 502 remaining after the combustion is processed in the process of incineration ash recovery 690.

  The process of the combustion gas delivery 680 sends the combustion gas 511 generated by the semi-carbide combustion 670 to the rotary kiln 200 for processing in the process of the traction 640. The combustion gas 511 is used to supply heat for generating the semi-carbides 501 from the litter 500 in the rotary kiln 200.

  In the incineration ash collection 690 step, the incineration ash 502 remaining in the semi-carbide combustion 670 is collected for use as fertilizer.

  Initially, since there is no semi-carbide 501 combusted in the combustion table 400, the combustion gas 511 for heating the rotary kiln 200 is not generated. Therefore, burnable fallen leaves such as withered cedar leaves as an igniter may be put into the rotary kiln 200 and sent to the combustion table 400 as it is, and then burned on the combustion table 400.

  As components of the incineration ash 502, nitrogen is 1530 mg / kg (0.15%), phosphoric acid is 45300 mg / kg (4.53%), potassium is 70300 mg / kg (7.03%), and the pH is 10. It was 5. In addition, the component in the case of only culm that does not contain horse dung is 0.06% nitrogen, 2.47% phosphoric acid, 10.0% potassium, pH is 10.2, incineration ash 502, It turns out that it is very effective as a fertilizer for agricultural products.

  As mentioned above, although the Example of this invention was described, it is not limited to these. For example, the present invention may be used not only in racehorse rearing ranches and stables but also in livestock rearing ranches such as cattle, pigs and chickens. In addition, rice straw or plants that do not contain animal dung may be semi-carbonized.
