[0001]
BACKGROUND OF THE INVENTION
TECHNICAL FIELD The present invention relates to a mozuku discharging device for a mozuku salting tank that can take out the mozuku stored in the salting tank in a fixed amount.
[0002]
[Prior art]
Conventionally, harvested raw mozuku has been salted, removed foreign matter with a visual sorting device, and then quantitatively filled with a metering filling machine. As shown in FIG. 12, first, the raw mozuku 1 is stored in a concrete mozuku salting tub 3 composed of about 10 to 10 tons and salted for about one week. And the on-off valve 5 provided in the lower part of the mozuku salt storage tank 3 used as the discharge device 15 is opened and drained for 12 to 24 hours, and the water | moisture content adhering to the salted mozuku 2 is reduced as much as possible. Subsequently, the gate 9 of the discharge port 7 is driven and opened by the cylinder C, and the salted mozuku 2 is discharged by an appropriate amount. The salted mozuku 2 is discharged to the basket 11 and guided to the visual sorting device 13. After removing the foreign matter from the salted mozuku 2 with this visual sorting device 13, it is pushed out into the hopper 19 of the metering and filling device 17 and metered and filled.
[0003]
According to the above-described conventional mozuku salting device for mozuku salting tanks, as shown in FIG. 13, the amount of water adhering to the salting mozuku 2 in the mozuku salting tank 3 is reduced during discharging, so the fluidity of the salting mozuku becomes poor. For this reason, even if the gate 9 used as the discharge device 15 of the discharge port 7 is opened a little, the salted mozuku 2 is not discharged. Therefore, if you open too much, you will be discharged as a big lump at a stretch, and you will be struck by the trouble of overflowing the jar 11. For this reason, there exists a problem that the discharge control which discharge | releases salted mozuku quantitatively is difficult. This means that there is a lot of or insufficient supply of mosk to the visual sorting device, and stable quantitative feeding cannot be performed, and high quality sorting cannot be performed.
[0004]
Therefore, as shown in FIG. 14, when the pump P is connected to the mosc discharge device 15 </ b> A of the mozuku salt storage tank 3 and forced suction discharge is performed, a cavity H is formed in the salt mozuku 2 in the mozuku salt storage tank 3, and air E is sucked. Therefore, there is a problem that the salted mozuku 2 cannot be efficiently and quantitatively discharged. Accordingly, in this case as well, there are many or insufficient mosks supplied to the visual sorting device, and stable quantitative feeding cannot be performed, and high quality sorting cannot be performed.
[0005]

[Action]
According to the mozuku salt discharge tank of the mozuku salt storage tank according to claim 1 of the present invention, there is provided a discharge storage chamber continuously extended to the discharge port opened at the lower part of the mozuku salt storage tank. A drain valve is provided to drain the water contained in the salted mozuku. In addition, an opening / closing valve is provided in the lower part of the discharge storage chamber, and a delivery pump is connected to the outlet side of the opening / closing valve. Thereby, the mozuku salted in the mozuku salting tank is in a filling state in which a part of the mozuku drops and moves by its own weight from the discharge port at the lower part of the mozuku salting tank.

A discharge port 51 is opened in the lower front surface 50 </ b> A of the mozuku salt storage tank 50. A box-shaped discharge storage chamber 53 is attached to the discharge port 51 directly below this via a confidential member K such as a packing material, and is continuously extended downward. A drainage valve 55 for discharging the water W contained in the salted mozuku 2 is attached at a suitable position below the discharge storage chamber 53. Further, an opening / closing valve 57 is provided below the discharge storage chamber 53. By opening / closing the on-off valve 57, the discharge of the salted mozuku 2 filled in the discharge storage chamber 53 is controlled. A delivery pipe 59 is connected to the outlet side of the on-off valve 57. A delivery pump 110 is connected to an intermediate portion of the delivery pipe 59. With this delivery pump 110, the salted mozuku 2 filled in the discharge storage chamber 53 is forcibly sucked and discharged.
[0018]
Note that, in the above-described mosk discharge device 100, the discharge storage chamber 53 may be disposed obliquely below the discharge port 51 as in the case of the mosk discharge device 200 of the second embodiment shown in FIG. According to the second embodiment, the salted mozuku 2 in the mozuku salting tank 50 is pushed by the weight of the salted mozuku 2 in the upper part of the mozuku salting tank 50, to the discharge storage chamber 53 arranged obliquely below the discharge port. It will flow and fill.
[0019]
A detailed configuration of the delivery pump 110 will be described with reference to FIGS. This delivery pump 110 is the same as Japanese Patent Application Laid-Open No. 11-341969 filed by the applicant of the present invention. The external appearance is as shown in FIGS. On the moving carriage 112, the two cylinder containers C1 and C2 are held in a vertical posture. In the cylinder containers C1 and C2, suction valves V1 and V2 are arranged at the upper part, and discharge valves V3 and V4 are arranged at the lower part. Although not shown, vacuum valves V5 and V6 and pressurizing valves V7 and V8 are provided above the cylinder containers C1 and C2. And it is equipped with the air compressor K, the vacuum pump P0, and the motor 115 which drives this, and the separator 10 is provided.
[0020]
Next, the circuit configuration of the delivery pump 110 will be described with reference to FIGS. The delivery pump 110 has cylinder containers C1, C2 connected to the opening / closing valve 57 of the discharge storage chamber 53 via suction valves V1, V2, and a discharge connected to the cylinder containers C1, C2 via discharge valves V3, V4. A pipe P1, P2, a vacuum pump P0 connected to the cylinder containers C1, C2 via vacuum valves V5, V6, and an air compressor K connected to the cylinder containers C1, C2 via pressure valves V7, V8.

[0021]
The delivery pump 110 adjusts the pressurizing force of the cylinder containers C1 and C2 and the opening amounts of the discharge valves V3 and V4 to adjust the salted mozuku per time that is pressurized and discharged from the cylinder containers C1 and C2. The discharge amount can be adjusted, whereby the transport amount per time for pressure discharge can be precisely controlled.
[0022]
According to the delivery pump 110, the two cylinder containers C1 and C2 are alternately operated by repeatedly changing between the pressurized state and the reduced pressure state. That is, the salted mozuku 2 stored in the mozuku salt storage tank 50 by alternately evacuating the cylinder containers C1 and C2 by the vacuum pump P0 is alternately sucked into the cylinder containers C1 and C2, and the cylinder by the pressurizing means K is used. By alternately pressurizing in the container, the salted mozuku 2 sucked into the cylinder container is alternately discharged from the discharge pipes P1 and P2. The discharged salted mozuku 2 is transferred toward the distal end side of the delivery pipe 59.
[0023]
As shown in FIGS. 2 and 5, the delivery pipe 59 connected to the delivery pump 110 from the open / close valve 57 of the mosk discharge devices 100 and 200 has its tip connected to the flat nozzle body 70 via the dehydrator 60. ing. The flat nozzle body 70 is disposed on the input side of the conveyor 81 in the conveyor-type visual sorting device 80. As shown in FIGS. 6 and 7, the discharge port 73 of the flat nozzle body 70 is formed in a flat cross section having a narrow vertical dimension and a horizontal dimension of the conveyor width. An illumination device 82 is disposed on the conveyor 81.
[0024]
As shown in FIGS. 2 and 5, a hopper 83 for receiving the selected salted mozuku 2A is arranged on the discharge side of the visual sorting device 80. A delivery pipe 85 is connected to the hopper 83. The delivery pipe 85 is disposed on the hopper 91 of the metering and filling device 90 via the delivery pump 110 and the on-off valve 87 having the same configuration as described above. Of course, a piping configuration in which the delivery pipe 59 is directly connected to the delivery pipe 85 without using the visual sorting device 80 and is disposed on the hopper 91 of the metering filling device 90 via the on-off valve 87 may be adopted.
[0025]
Mozuku discharge devices 100 and 200 according to the present invention are configured as described above and operate as follows. First, in the mozuku discharge device 100 shown in FIG. 3, a discharge storage chamber 53 is provided which extends continuously downward from the discharge port 51 opened at the lower portion of the mozuku salt storage tank 50, and opens and closes to the discharge storage chamber. A valve 57 is provided, and a delivery pump 110 for forcibly discharging and discharging is connected to the on-off valve 57. Thereby, the mozuku 2 salted in the mozuku salt storage tank 50 is in a filled state in which a part of the mozuku 2 falls and moves by its own weight from the discharge port 51 at the lower part of the mozuku salt storage tank.
[0026]
In addition, in the mozuku discharge device 200 shown in FIG. 4, a discharge storage chamber 53 that is formed to extend obliquely downward continuously to the discharge port 51 opened in the lower portion of the mozuku salt storage tank 50 is provided. An open / close valve 57 is provided, and a discharge pump 110 forcibly sucking and discharging is connected to the open / close valve 57. As a result, the mozuku 2 salted in the mozuku salting tank 50 is partially pushed to the weight of the salted mozuku 2 at the upper part of the mozuku salting tank 50 from the discharge port 51 at the lower part of the mozuku salting tank to the discharge storage chamber 53. Then, it flows into a discharge storage chamber 53 disposed obliquely below the discharge port and enters a filled state.
[0027]
Here, while opening the on-off valve 57 and starting the delivery pump 110, the salted mozuku 2 in the discharge storage chamber 50 is forcibly sucked and discharged by an appropriate amount. By the action of forced suction and discharge by the delivery pump 110, the salted mozuku 2 in the small volume discharge storage chamber 53 is forcibly sucked and discharged. At this time, the inside of the discharge storage chamber 53 is in a negative pressure state and tries to create a cavity, but the salt storage mozuku 2 in the mozuku salt storage tank is forced to discharge and store due to the natural fall due to its own weight and the negative pressure in the discharge storage chamber. It is drawn into the room. By acting in this way, the salted mozuku 2 flows smoothly into the discharge storage chamber 53 and is continuously discharged to the next process via the delivery pipe 59 without sucking air.
[0028]
As described above, when the salted mozuku 2 is forcibly sucked and discharged by the delivery pump 110 connected to the mosk discharging device 100 of the mozuku salting tank 50, the salted mozuku is surely discharged quantitatively. Therefore, since the salted mozuku discharged quantitatively can be quantified and evenly supplied to the visual sorting device 80, a good visual sorting operation can be performed. Also, the metering and filling device 90 can perform a smooth metering and filling operation.
[0029]
In particular, the salted mozuku 2 forcedly sucked and discharged from the delivery pump 110 has a flat cross section with the flat nozzle body 70 having a narrow vertical dimension and a horizontal dimension of the conveyor width. It is pushed out by a predetermined width and discharged. Thereby, the removal operation | work of the foreign material in the visual selection apparatus 80 can be done easily.
[0030]
Further, since the discharge storage chamber 53 is arranged directly below the discharge port 51, the salt mozuku 2 stagnating in the lower part of the mozuku salt storage tank 50 is placed in the discharge storage chamber 53 directly below the discharge port 51 from its own weight. It falls naturally due to the gravity action of, allowing even smoother salted mozuku quantitative discharge.
[0031]
By adopting the delivery pump 110, the salted mozuku 2 discharged by forced suction is not cut and can be quantitatively discharged while maintaining a good quality state.
[0032]
The present invention is not limited to the above embodiment. For example, the delivery pump 110 employs a suction / discharge type pump using a cylinder to prevent the salted mozzar from being cut. However, in the case where the cutting of Mozuku is allowed to some extent, a plunger pump in which a plunger piston reciprocates in the cylinder, a slide vane type rotary pump, a deformed screw pump, or the like can be used instead of the delivery pump 110.
[0033]
Further, the shape of the discharge storage chamber 53 is only required to be extended downward so as to exhibit the effects of the present invention, and the shape may be changed as appropriate. Further, the types of the on-off valve 57 and the drain valve 55 may be changed to other types, and their installation positions may be changed as appropriate.
[0034]
