Description

[0001]
[Industrial application fields]
The present invention relates to a device for separating and removing fresh seaweed foreign matter (trash, shrimp, thread, etc., the same shall apply hereinafter), and used for separating foreign matter from a raw nori mixed solution (a mixture of raw nori and salt water in an appropriate concentration). It is what is done.
[0002]
[Prior art]
In this type of foreign matter separation and removal apparatus in the past, the outer peripheral edge of the annular frame plate portion is connected to the peripheral edge of the bottom portion of the mixed liquid tank, and a rotating plate is installed inside the annular frame plate portion. Since a clearance is formed between the rotating plate and the annular frame plate portion, and the rotating plate can be appropriately rotated around the axis by rotation driving means, and a foreign matter discharge port is provided at the bottom corner of the tank, By rotating the rotating plate, foreign matter having a specific gravity greater than that of raw nori is accumulated by centrifugal force on the annular frame plate side, i.e., at the bottom corner of the tank, and only the raw nori is added to the clearance with water. As a result of passing and flowing downward, the clearance is less likely to be clogged with foreign matter, so there is no need to separately provide a cleaning device or the like, and the device is easy to maintain and easy to handle, Were capable of improving the working efficiency of the seaweed of the foreign matter separation removal operation (JP-A-8-140637).
[0003]
[Problems to be solved by the invention]
However, even in such a conventional foreign matter separating and removing apparatus, there is a rare case where foreign matter is clogged in the clearance, and thus the clogged foreign matter has to be removed.
[0004]
An object of the present invention is to eliminate such inconvenience.
[0005]
[Means for Solving the Problems]
In order to achieve the above object, in the apparatus for separating and removing fresh seaweed foreign matter according to the present invention, the outer peripheral edge of the annular frame plate portion is connected to the peripheral edge of the bottom of the mixed liquid tank, and the inner side of the annular frame plate portion. And a clearance between the rotating plate and the annular frame plate portion, and the rotating plate can be appropriately rotated by an electric motor about the axis, and a foreign matter discharge port at the bottom of the tank. In the apparatus for separating and removing foreign matter from fresh seaweed, the motor is provided with a current relay, and when the clearance is clogged with foreign matter and the current relay detects a current value greater than or equal to a predetermined value, the motor is reversely rotated via a control unit. Therefore, when the clearance is clogged with foreign matter and the load current of the electric motor increases and reaches a predetermined value, the current relay operates and the control unit is The motor Te, hence, the rotation plate is rotated in the reverse direction along the rotation axis results, the foreign matter jammed in the clearance is one which is easily pushed out to the mixture in the tank while being pushed in the direction of approach and backward.
[0006]
The motor is provided with a current relay, and when the clearance is clogged with foreign matter and the current relay detects a current value greater than or equal to a predetermined value, pressurized water is ejected from the downstream side of the clearance toward the upstream side through the control unit. In this way, the foreign matter clogged in the clearance is easily pushed out into the liquid mixture tank while being pushed in the direction opposite to the intrusion direction.
[0007]
If the current value can be varied, the clogging state of the foreign object to be rotated in the reverse direction can be changed.

The liquid level upper limit level sensor 54 controls the supply of the mixed liquid and water into the mixed liquid tank 10 (stops the supply of the mixed liquid or water when the mixed liquid reaches a predetermined amount in the tank). Further, if the liquid level lower limit level sensor 55 raises the first rotary plate 26 and the second rotary plate 36 when it detects the lower limit of the mixed liquid, it can easily collect the extruded foreign matter. It is.
[0021]
Next, the operation of the foreign matter separation and removal apparatus D will be described.
[0022]
First, a raw nori mixed solution (a mixture of raw nori and salt water having an appropriate concentration) is supplied into the mixed solution tank 10 through the raw material supply pipe 53. At this time, both the first separation / removal tool 20 and the second separation / removal tool 30 are in the normal state, that is, the state of the first separation / removal tool 20 in FIG. 1 (see FIG. 4). In this state, the motors 21 and 31 are driven to rotate the first rotating plate 26 and the second rotating plate 36 in the forward direction. Then, in the first separation / removal tool 20 and the second separation / removal tool 30, the mixed liquid in the mixed liquid tank 10 generates a vortex, and small foreign matters in the mixed liquid are transferred to the first rotary plate 26 and the second rotary plate 36. It accumulates on the first annular fixing plate 23 or the second annular fixing plate 33 side beyond the clearance C by centrifugal force. For this reason, only raw nori flows through the clearance C together with water and flows downward. At this time, since the first rotating plate 26 and the second rotating plate 36 are rotating, the fresh seaweed is hardly clogged in the clearance C. In rare cases, the clearance C may be clogged with foreign matter. When the foreign matter is clogged in the clearance C, the load current flowing through the first motor 21 or the second motor 31 rises to a predetermined value (preset) or more, so that the current relays (variable) 212, 312 are activated. Then, the first motor 21 or the second motor 31 is reversely rotated via the control units (control circuits) 213 and 313. Then, while the motors 21 and 31 are rotating in the reverse direction, the first rotating plate 26 and the second rotating plate 36 are brought into the state of the second separation / removal tool 30 in FIG. Raise relative to the one annular fixing plate 23 or the second annular fixing plate 33 (see FIG. 5). Then, since the foreign matter clogged in the clearance C is pushed out in the direction opposite to the intrusion direction, it is very easily returned to the mixed liquid tank 10. The returned foreign matter is discharged from the discharge pipe 51 together with other foreign matters.
[0023]
On the other hand, the mixed liquid from which foreign substances have been removed flows out into the batch water tank B through the outflow pipe 52. In addition, when the liquid level detection sensor of the batch water tank B detects the upper limit, if the first rotary plate 26 and the second rotary plate 36 are reversely rotated to raise, The separated liquid mixture can be always supplied.
[0024]
As indicated by phantom lines (two-dot chain lines) in FIG. 1, instead of rotating the motors 21 and 31 in reverse, pressurized water supply pipes 219 and 319 are provided in the brackets 211 and 311 so that the current relays 212 and 312 have a current value greater than a predetermined value. Is detected, the pumps 218 and 318 are operated via the control units 213 and 313, and the pressurized water is ejected from the downstream side of the clearance C to the upstream side via the pressurized water supply pipes 219 and 319, and the clogged foreign matter enters the mixed liquid tank 10. It can also be returned.
[0025]
FIG. 7 shows another embodiment, in which the peripheral end portion of the rotating plate 36 is arranged above the second annular fixed plate 33. In this case, the clearance C is formed horizontally. The first separation / removal tool 20 can have the same configuration.
[0026]
