Description

  The present invention relates to a device for avoiding the generation of small foreign matter in a foreign matter separator for laver mixed liquid.

  As a conventional foreign matter separation device for laver mixed liquid (foreign matter separator for laver mixed solution), Japanese Patent Laid-Open No. 8-140637, “Natural foreign matter separation and removal device” (referred to as reference (1)), Japanese Patent Laid-Open No. 2004-2004. No. 357640 “foreign substance separation device for seaweed mixture” (patented by the applicant of the present invention, referred to as reference (2)), or Japanese Patent Laid-Open No. 2000-139424 “foreign seaweed foreign matter separation method, foreign matter separator and foreign matter removal” Apparatus "(referred to as document (3)). In the laver operation in the foreign matter separating apparatus for the laver mixture, the laver mixture (raw laver mixture) is repeatedly introduced (introduced) into the tank in an intermittent manner. The introduced nori mixed liquid is separated into raw nori and foreign matter using a gap between the bottom surface of the tank and a rotating member (rotating plate, rotating part, etc.). And the separated foreign matter is retained in the tank. The operations such as guiding the raw seaweed to the non-defective tank and retaining the foreign matter in the tank are repeated (referred to as sorting operation). This sorting operation usually sets a time of about 5 to 8 minutes. During this set time, the laver mixture is repeatedly and intermittently introduced, and most of the introduced raw laver is sucked through the gap and decreases, while the foreign matter remains in the tank. Therefore, the foreign matter in the laver mixture in the tank is increased by sequentially and repeatedly charging the laver mixture with the intermittent method. Since foreign matter increases in the tank, foreign matter increases with respect to the raw nori in the tank, and the amount of raw nori inhaled from the gap and the suction port is reduced, resulting in a reduction in processing capacity and efficient. Manufacturing is not possible, and the number of manufactured sheets is also reduced. On the other hand, if foreign matter increases with respect to the raw laver in the tank, a large amount of this foreign matter is sucked in, so that it is crushed, cut, crushed, etc. in the gap, and small foreign matter is likely to be generated. And if this small foreign material reaches the non-defective tank, there is a high probability that the small foreign matter will be mixed into the dried seaweed (seaweed product), causing a very serious problem such as lowering the quality and lowering the price. Easy to do. For this reason, in the laver work (site) at the site, usually, while a large amount of fresh seaweed remains in the tank, that is, at an early stage, the seawater is discharged while being injected. However, since such an operation (apparatus and / or method) can be considered only as a small-hand method and not an essential solution, it is considered an urgent need to avoid the occurrence of small foreign matter.

  Conventionally, in order to avoid the generation of small foreign matter, the gap is frequently adjusted, and this gap is determined in consideration of raw laver and / or the type / mixing amount / size of foreign matter. To do. However, since this raw nori and / or foreign matter changes every moment depending on the natural conditions of the nori fishery, such as the relationship with rainwater, the temperature, the seawater, the environment of the nori fishery, etc. Adjustment of the gap has a problem that requires skill and / or training (research and fine control). If the gap is adjusted incorrectly, a small foreign matter is generated, and this small foreign matter reaches a non-defective tank. This causes problems such as a decrease in the quality of dry seaweed and a reduction in the cost of dry seaweed. .

  From the above, the performance of this type of foreign matter separator is evaluated based on the number of dry laver containing foreign matter. For example, when the dry seaweed mixed with foreign matter in the dry seaweed is 3 to 5%, it is acceptable, and when it exceeds 10 to 20%, it is impossible. The small foreign matter is a fine foreign matter that passes through a gap of 0.1 mm or less, and is a leaf of bamboo leaves, straw debris, withered flat mole, and shrimp of shrimp.

  References (4) and (5) may be cited as other references intended to separate and remove small foreign matters, etc., with respect to the foreign matter separation apparatus for the laver mixed liquid described in References (1) to (3).

  Document (4) is a “raw seaweed foreign matter removing device” disclosed in Japanese Patent Laid-Open No. 9-94079. The present invention is configured to separate foreign matters larger than the original algae (raw nori) with the first foreign matter separating means and foreign matters smaller than the original algae with the second foreign matter separating means. However, there is a description that this invention adjusts the injection amount of seawater and uses the first and second foreign matter separating means, but there is no specific description about the configuration and means, and there is doubt about the contents of the invention. is there. Further, the present invention only improves the removal rate of foreign matter by the first and second foreign matter separating means.

  Reference (5) is “a method and an apparatus for separating foreign matter from raw seaweed” disclosed in Japanese Patent Application Laid-Open No. 2003-250501. This invention guides raw nori and water from which large foreign substances have been separated to a separation tank, and while stirring in this separation tank, increases the water pressure inside, and discharges the fine foreign substances and water from the micropores in the separation tank, A method and apparatus for separating raw seaweed from minute foreign matter. This invention intends to improve the cleanliness of fresh seaweed by effectively separating minute foreign substances. However, the large foreign matter remaining in the raw nori is problematic because it cannot pass through the minute gaps and still remains in the raw nori.

Japanese Patent Laid-Open No. 8-140637 JP 2004-357640 A JP 2000-139424 A JP-A-9-94079 JP 2003-250501 A

  The above-mentioned document (2) corresponds to the gap (corresponding to the first gap of the present invention) in order to improve the removal rate of the foreign substance separator of the laver mixed liquid (corresponding to the foreign substance separator of the laver mixed liquid of the present invention). ) Is set as narrow as possible, for example, the gap before operation is set to substantially zero. However, this gap can vary (open) due to slight manufacturing tolerances and negative pressure action due to the suction pressure of the suction pump during operation. And, since the seaweed algae and / or foreign matter is greatly different depending on the collection time and natural conditions of the seaweed raw algae and / or the environment of this seaweed fishing ground, as described above, it is easy for small foreign matter to pass through the device with a variable gap, The removal rate becomes worse. Therefore, in order to further reduce the gap during operation, it is necessary to set the gap at the time of stop to 0 (minus state) from 0. On the other hand, an adverse effect occurs when the gap is set to be negative. For example, when a phenomenon occurs in which air is mixed into the pump suction at the start of operation and the negative pressure suddenly disappears, the gap returns to minus, and a rustling noise is generated. (Casing) wear occurs. As described above, there is a demand for expansion of the setting allowable range of the gap and avoiding wear of the rotating member and / or the bottom surface of the tank.

  Documents (1) and (3) have a configuration in which a gap is formed between the rotating member and the bottom surface of the tank, and there is a limit to fine adjustment of the gap, which is considered impossible with an actual machine. Further, in order to make this gap minute, it is almost impossible to consider the manufacturing tolerance, and it is considered difficult to carry out with the actual machine. Further, there is a probability that the bottom surface of the rotating member and / or the tank is worn. Therefore, also in this literature (1) and (3), expansion of the setting tolerance | permissible_range of a clearance gap and the avoidance of abrasion of the rotating member and / or the bottom face of a tank are desired.

An example of the present invention will be described.
First, the drawings will be described. FIG. 1 is an overall cross-sectional schematic diagram showing the first embodiment, FIG. 2 is an overall cross-sectional schematic diagram showing the second embodiment, and FIG. 3 is an overall cross-sectional view showing the third embodiment. FIG. 4 is a schematic cross-sectional view of the whole of the fourth embodiment.

  The first embodiment shown in FIG. 1 will be described. Reference numeral 1 denotes a tank for a laver mixture of the foreign matter separator A. The tank 1 has a laver mixture injection pipe 2 and a washing water injection pipe 3 (a laver mixture). Each of which may also be used for dilution). A space plate 4 of the tank 1 is provided with a substantially deep-plate-shaped rotating plate 6 (rotating member) through a gap 5, and the rotating plate 6 is supported by a rotating shaft 60 and has a motor 61. Rotate through. Further, the tank 1 is provided with a suction port 8 to which a hose 70 for guiding the selected raw laver to the non-defective tank 7 is connected. Further, the tank 1 is provided with a foreign matter discharge port 90 for communicating with the foreign matter discharge pipe 9. In the figure, 91 indicates a valve provided in the foreign matter discharge pipe 9 and 71 indicates a pump provided in the hose 70. In the first embodiment, the motor 61, the pump 71 or the valve 91 is connected to the stop control means 12. The stop control means 12 can individually stop and / or control the motor 61, the pump 71, or the valve 91 (timer control, the same applies hereinafter). It is also possible to control the rotational speed of the motor 61 and the opening degree of the pump 71 or the valve 91. This individual stop and / or control, control of the number of revolutions, etc., take into account the state of raw nori and / or foreign matter, its mixing ratio, etc. It has features such as being able to contribute to quality improvement. In the figure, reference numeral 13 denotes a liquid level sensor provided in the tank 1.

Next, the sorting operation of the first embodiment will be described. While the laver mixed liquid is introduced (supplied) into the tank 1 from the laver mixed liquid introducing pipe 2, the rotating plate 6 of the tank 1 is rotated. The rotation of the rotating plate 6 causes the raw nori in the introduced laver mixed solution to rotate (swivel flow) while spreading, and is sucked in through the gap 5 so as to be sucked during the rotation. To the non-defective tank 7 through the hose 70. In addition, foreign matters and / or fresh seaweed that are not sucked through the gap 5 (cannot pass through the gap 5) are retained (remain) on the bottom surface of the tank 1. This series of movements is called sorting work. During this sorting operation, the laver mixture is repeatedly charged intermittently, so that the foreign matter in the laver mixture in the tank 1 increases as described above. As foreign matter increases in the tank 1, foreign matter increases with respect to the raw nori in the tank 1, the amount of raw nori sucked from the gap 5 and the suction port 8 is reduced, and processing capacity is reduced. However, efficient manufacturing cannot be achieved, and the number of manufactured sheets also decreases. On the other hand, when foreign matter increases with respect to the raw nori in the tank 1, a large amount of this foreign matter is sucked in, so that the foreign matter is crushed, cut, crushed, etc. in the gap 5, and small foreign matter is generated. 7, there is a high probability that small foreign matter is mixed in the dry seaweed, and extremely serious problems such as deterioration in quality and price are likely to occur. Therefore, in the present invention, based on the detection of the mixing ratio (detection by optical means such as an optical sensor, LED, etc.), as a main and / or incidental condition, for example, a laver mixture is introduced into the tank 1. When the detection means 15 for detecting the number of times, time, or the amount of the foreign matter accumulated in the tank 1 is set, and the detection means 15 for detecting the condition such as the mixing rate that can be inferred, the stop control means 12 uses the motor 61, the pump 71, or the valve 91. The small foreign matter generated in the gap 5 is eliminated by using a means such as selectively stopping and / or integrally stopping. Therefore, when this small foreign matter is generated, it is possible to eliminate the labor and work based on the discharge and removal of this small foreign matter, and simplification, facilitation or shortening of cleaning, facilitation or shortening of the discharge time. There is an actual benefit such as being able to make it. After this sorting operation is performed for about 5 to 8 minutes, the foreign matter retained on the bottom surface of the tank 1 rotates with water injection of seawater or the like into the tank 1 through the washing water injection pipe 3 and if necessary. The plate 6 is rotated, and the foreign matter accumulated on the bottom of the tank 1 is discharged to a container outside the tank 1 through the foreign matter discharge pipe 9 together with some raw laver. The discharged raw seaweed (discarded seaweed) is intended to be reused in principle and to avoid environmental destruction due to pollution and / or salt damage through this reuse.
In addition, although the example which made the rotating plate 6 the substantially deep dish type | mold was demonstrated, it is also possible to substitute for a plate shape and a substantially bowl shape, and the effect does not have an inferiority (other examples are also the same).

  Referring to the second embodiment shown in FIG. 2, reference numeral 21 denotes a nori mixed liquid tank of the foreign matter separator A. The tank 21 has a nori mixed liquid input pipe 22 and a washing water injection pipe 23 (a nori mixed liquid). Each of which may also be used for dilution). In addition, a substantially plate-shaped rotating plate 26 (rotating member) is provided in the space portion 24 of the tank 21 via a gap 25, and the rotating plate 26 is supported by a rotating shaft 260 via a motor 261. Rotate. Further, the sorting casing 210 provided below the tank 21 is provided with a suction port 28, and the suction port 28 is connected with a hose 270 that guides the sorted raw laver to the non-defective tank 27. Further, the tank 21 is provided with a foreign matter discharge port 290 for communicating with the foreign matter discharge pipe 29. In the figure, reference numeral 291 denotes a valve provided in the foreign matter discharge pipe 29, and reference numeral 271 denotes a pump provided in the hose 270. In this second embodiment, the motor 261, the pump 271 or the valve 291 is connected to the stop control means 212. The stop control means 212 can also stop and / or control the motor 261, the pump 271 or the valve 291 individually. It is also possible to control the rotational speed of the motor 261 and control the opening degree of the pump 271 or the valve 291.

In the figure, reference numeral 213 denotes a liquid level sensor provided in the tank 21.

Next, the sorting operation of the second embodiment will be described. The laver mixed solution is introduced (supplied) into the tank 21 through the laver mixed solution introducing tube 22 and the rotating plate 26 of the tank 21 is rotated. As the rotating plate 26 rotates, the raw laver in the mixed laver mixture rotates while rotating (swirling) and is sucked through the gap 25 so as to be sucked during the rotation. To the non-defective tank 27 via the hose 270. Further, foreign matters and / or fresh seaweed that are not sucked through the gap 25 (cannot pass through the gap 25) are retained (remain) on the bottom surface of the tank 21. This series of movements is called sorting work. During this sorting operation, the laver mixture is repeatedly charged intermittently, and as described above, foreign matter in the laver mixture in the tank 21 increases. As foreign matter increases in the tank 21, foreign matter increases with respect to the raw nori in the tank 21, the amount of raw nori sucked from the gap 25 and the suction port 28 is reduced, and the processing capacity is reduced. However, efficient manufacturing cannot be achieved, and the number of manufactured sheets also decreases. On the other hand, when foreign matter increases with respect to the raw nori in the tank 21, a large amount of this foreign matter is sucked in, so that the foreign matter is crushed, cut, crushed, etc. in the gap 25, and small foreign matter is generated. If it reaches 27, there is a high probability that small foreign matter will be mixed in the dry seaweed, and very serious problems such as a reduction in quality and a decrease in price are likely to occur. Therefore, in the present invention, based on the detection of the mixing ratio (detection by optical means such as a light sensor, LED, etc.), as a main and / or incidental condition, for example, a laver mixture is introduced into the tank 21. When the detection means 215 detects conditions such as the number of times, time, or the amount of foreign matter accumulated in the tank 21 and detects a condition such as a mixing rate that can be inferred, the stop control means 212 uses the motor 261, pump 271, or valve 291. This is a configuration in which small foreign matter generated in the gap 25 is eliminated by using means such as selectively stopping and / or integrally stopping. Therefore, when this small foreign matter is generated, it is possible to eliminate the labor and work based on the discharge and removal of this small foreign matter, and simplification, facilitation or shortening of cleaning, facilitation or shortening of the discharge time. There is an actual benefit such as being able to make it. After this sorting operation is performed for about 5 to 8 minutes, the foreign matter retained on the bottom surface of the tank 21 is injected with water such as seawater through the washing water injection pipe 23 to the tank 21 and rotated as necessary. The plate 26 is rotated, and the foreign matter accumulated on the bottom of the tank 21 is discharged to a container outside the tank 21 through the foreign matter discharge pipe 29 together with some raw laver. The discharged raw seaweed (discarded seaweed) is intended to be reused in principle and to avoid environmental destruction due to pollution and / or salt damage through this reuse.
In addition, although the example which made the rotating plate 26 the substantially plate shape was demonstrated, it can replace with a substantially deep dish type | mold and a substantially bowl shape, and the effect is not inferior (other examples are also the same).

Further, the tank 31 is provided with a foreign matter discharge port 390 for communicating with the foreign matter discharge pipe 39. In the figure, reference numeral 391 denotes a valve provided in the foreign matter discharge pipe 39, and reference numeral 371 denotes a pump provided in the hose 370. Further, in this third embodiment, as shown in the figure, a large number of space portions 34 are formed at the bottom of the tank 31, and a large number of annular protrusions of a substantially plate-shaped rotating plate 36 are formed in the large number of space portions 34. 362 is inserted, and the space 35 and the annular protrusion 362 form a plurality of annular gaps 35. In the third embodiment, the motor 361, the pump 371 or the valve 391 is connected to the stop control means 312. The stop control means 312 can also stop and / or control the motor 361, the pump 371, or the valve 391 individually. It is also possible to control the number of rotations of the motor 361 and the opening degree of the pump 371 or the valve 391. This individual stop and / or control, control of the number of revolutions, etc., take into account the state of raw nori and / or foreign matter, its mixing ratio, etc. It has features such as being able to contribute to quality improvement. In the figure, reference numeral 313 denotes a liquid level sensor provided in the tank 31.

  Next, the sorting operation of the third embodiment will be described. While the laver mixed solution is introduced (supplied) into the tank 31 from the laver mixed solution introducing tube 32, the rotating plate 36 of the tank 31 is rotated. The rotation of the rotating plate 36 causes the raw laver in the introduced laver mixed liquid to rotate (swivel flow) while spreading, and is sucked through the gap 35 so as to be sucked during the rotation, and is sucked into the suction port 38. To the non-defective tank 37 via the hose 370. In addition, foreign matters and / or fresh seaweed that are not sucked through the gap 35 (cannot pass through the gap 35) are left on the bottom surface of the tank 31 (remain). This series of movements is called sorting work. During this sorting operation, the laver mixture is repeatedly input intermittently, and as described above, foreign matter in the laver mixture in the tank 31 increases. As foreign matter increases in the tank 31, foreign matter increases with respect to the raw nori in the tank 31, and the amount of raw nori sucked from the gap 35 and the suction port 38 is reduced, resulting in a reduction in processing capability. However, efficient manufacturing cannot be achieved, and the number of manufactured sheets decreases. On the other hand, when foreign matter increases with respect to the raw nori in the tank 31, a large amount of this foreign matter is sucked in, so that the foreign matter is crushed, cut, crushed, etc. in the gap 35, and small foreign matter is generated. If it reaches 37, there is a high probability that small foreign matter will be mixed in the dry seaweed, and extremely serious problems such as a reduction in quality and a reduction in price are likely to occur. Therefore, in the present invention, based on the detection of the mixing ratio (detection by optical means such as a light sensor and LED), and as a main and / or incidental condition, for example, a laver mixture is introduced into the tank 31. When the detection means 315 detects conditions such as the number of times, time, or accumulation amount of the foreign matter in the tank 31 and detects conditions such as a mixing rate that can be inferred, the stop control means 312 uses the motor 361, pump 371, or valve 391. The third embodiment is configured to eliminate small foreign matters that are frequently generated in a large number of annular gaps 35 by utilizing means such as selectively stopping and / or integrally stopping. Therefore, it is possible to eliminate the labor and work based on the discharge and removal of small foreign matters that often occur in the annular gaps 35 formed by the multiple strips, and simplification, facilitation, or shortening, facilitation or discharge of the sorting operation. There are real benefits such as shortening of time. After this sorting operation is performed for about 5 to 8 minutes, the foreign matter retained on the bottom surface of the tank 31 is injected with water such as seawater by the washing water injection pipe 33 to the tank 31 and rotated as necessary. The plate 36 is rotated, and the foreign matter accumulated on the bottom of the tank 31 is discharged to a container outside the tank 31 through the foreign matter discharge pipe 39 together with some raw laver. The discharged raw seaweed (discarded seaweed) is intended to be reused in principle and to avoid environmental destruction due to pollution and / or salt damage through this reuse.
