Description

The present invention relates to a continuous transfer pump device that enables a granular transfer object to be continuously transferred with a small amount of water to a high concentration with a high yield.
Here, as the “particulate transfer object”, for example, various fish eggs such as salmon roe, masuko and caviar can be assumed.
In this case, “high concentration with a small amount of water” means that the content ratio (content ratio) of the fish egg in the total amount of water (liquid) and fish egg (particulate transfer object) in a unit volume is high. Refers to that.
In addition, “good yield” means that the fish eggs are transported without being broken (broken or damaged).

  By the way, as a conventional pump device, for example, a device that transfers a fish egg by controlling a wide (thick) impeller to reversely rotate, or a device that transfers a fish egg by high water pressure is known. . However, each pump device requires a large amount of water when transferring the fish eggs, and as a result, there is a problem that the fish eggs cannot be transferred at a high concentration.

  In particular, in the pump device using the impeller described above, since the wide (thick) impeller cannot be rotated at a high speed, there is a limit to the transfer force with respect to the fish egg. I can't. On the other hand, since the above-described pump device using water pressure requires a large amount of water, not only cannot a fish egg be transported at a high concentration, but also because a high water pressure acts on the fish egg. The egg may be broken (broken or damaged), and the yield cannot be kept constant.

  The present invention has been made to solve such a problem, and the object thereof is to provide a continuous transfer pump capable of transferring a granular transfer object continuously in a high concentration with a small amount of water with a high yield. To provide an apparatus.

In order to achieve such an object, the present invention can accommodate a granular transfer object together with a predetermined liquid, and the transfer object in a combined amount of the liquid and the transfer object in a unit volume. A retention pipe structure that retains in a state where the content ratio is increased, and a pump structure that is provided on the upper side of the retention pipe structure and that is connected to the retention pipe structure are accommodated together with the liquid. The object to be transported staying in the pump is continuously pumped and transferred together with the liquid while maintaining the state in which the content ratio with respect to the liquid is increased by the pump structure.
In the present invention, the inner diameter W1 of the pipe in which the object to be transferred is accommodated together with the liquid in the staying pipe structure, and the inner diameter W2 of the portion that pumps the object to be transferred together with the liquid in the pump structure satisfies the relationship of W1 <W2. It is set to be.
In the present invention, when W2 is 100%, W1 is set in the range of 40% to 70%.
In the present invention, the pump structure is composed of one or a plurality of pumps. When a plurality of pumps are used, pumping and transferring processes in each pump are alternately performed by alternately operating adjacent pumps.
In the present invention, the granular transfer object is various fish eggs separated into particles by a predetermined processing.

  ADVANTAGE OF THE INVENTION According to this invention, the continuous transfer pump apparatus which enabled the granular transfer target object to be continuously transferred to a high concentration with a small amount of water with a sufficient yield can be realized.

The perspective view which expands and shows partially the structure of the drive mechanism of the pump apparatus for continuous transfer which concerns on one Embodiment of this invention. The figure for demonstrating the operation | movement while partially showing the principal structure of the pump apparatus for continuous transfer which concerns on one Embodiment of this invention.

Hereinafter, a pump device for continuous transfer according to an embodiment of the present invention will be described with reference to the accompanying drawings.
In this embodiment, in the pump device for continuously transferring granular transfer objects, various granular eggs (for example, salmon roe, masuko, caviar) separated into particles by a predetermined processing process as the granular transfer objects. Etc.).

  As shown in FIG. 1, the pump device for continuous transfer according to this embodiment includes a granular fish egg (transfer object) together with a predetermined liquid (for example, a saline solution whose salt concentration is adjusted to about 1 to 5%). From the retention tube structure 2 that can be stored and retained in a state in which the content ratio (content ratio) of the fish egg in the combined amount of the liquid and the granular fish egg in the unit volume is increased, and the retention tube structure 2 Is also provided on the upper side, and includes a pump structure 4 connected to the staying pipe structure 2 in communication therewith.

  In this case, one of the gist according to the technical idea of the present invention is that the stay pipe structure 2 is provided on the lower side of the pump structure 4, and the stay pipe structure 2 (pipe 2t) has a granular shape. The fish eggs (transfer objects) are accommodated and retained in a high concentration state.

  Here, “the state in which the content ratio (content ratio) of the fish egg is increased” means that the total amount of the liquid egg and the granular fish egg in the unit volume is 100%. This means that the content ratio (content ratio) is 30% or more (preferably 40% or more, more preferably 50% or more), in other words, “a high concentration state with a small amount of water”.

  In addition, a reciprocating pump or a rotary pump can be used as the pump structure 4, but in this embodiment, as an example of the reciprocating pump, the piston in the cylinder is reciprocated between check valves and pumped and transferred. A piston pump that performs (delivery) processing is assumed.

  In such a continuous transfer pump device, the retention pipe structure 2 is connected to a concentration adjusting mechanism 6 for adjusting the content ratio (content rate) of fish eggs to an increased state (high concentration state). The concentration adjusting mechanism 6 injects into the concentration adjusting container 6a a concentration adjusting container 6a connected to the staying pipe structure 2 and a predetermined liquid (for example, a saline solution whose salt concentration is adjusted to about 1 to 5%). And a water injection conduit 6b.

  According to the concentration adjusting mechanism 6, when the eggs separated in a granular form by the predetermined processing are supplied to the concentration adjusting container 6 a, a small amount of liquid (1 to 5) is supplied from the water injection pipe 6 b in synchronization with this. % Salt solution) is poured into the concentration adjusting container 6a, so that the above-described fish egg adjusted to the high concentration state can be realized.

  In addition, the retention tube structure 2 communicates with the concentration adjusting container 6a and extends toward the lower side thereof, so that the fish egg adjusted to a high concentration state has a small amount of liquid (1 to 5% saline). ) And free fall from the concentration control container 6a (that is, the fish egg and the liquid fall by its own weight) and are accommodated in the pipe 2t constituting the stay pipe structure 2. Since the pipe 2t can be easily connected and disassembled via the coupling tool G, the pipe 2t can be arbitrarily selected according to the purpose and environment of use of the continuous transfer pump device or the size and shape of the installation place. Can be extended and shortened.

  Although the pump structure 4 can be composed of one or a plurality of piston pumps 4p, the pump structure 4 composed of two piston pumps 4p is shown as an example in the drawings. In this case, a plurality of pipes 2t of the above-described staying pipe structure 2 are prepared and connected to each other by a connecting tool G, so that two piston pumps 4p are connected to the upper side of the staying pipe structure 2 (pipe 2t). Can be made.

  The two piston pumps 4p have the same configuration, the cylinder 8 connected to the staying pipe structure 2 (pipe 2t), the piston 10 movable along the cylinder 8, and the upper part of the piston 10 And a piston rod 12 which is connected to the side and reciprocates (vertically moves) the piston 10.

  The cylinder 8 is provided with a seal body 14 inside the cylinder 8 on the side opposite to the cylinder lower part (upper part of the cylinder) communicating with the staying pipe structure 2 (pipe 2t). It is kept sealed from. As a result, for example, foreign matter such as water and dust is prevented from entering the cylinder 8, and the inside of the cylinder 8 is always kept clean and clean.

  In addition, a discharge pipe 16 is connected to the cylinder 8 at a portion near the seal body 14, and the discharge pipe 16 is connected to a delivery pipe 20 through a junction pipe 18. A cover tube 22 is connected to the cylinder 8 from the upper portion of the cylinder, so that the piston rod 12 is not exposed to the outside. In this case, the cylinder 8, the discharge pipe 16, the merging pipe 18, the delivery pipe 20, and the cover pipe 22 are easily configured to be connected and disassembled via the coupling tool G.

  The piston 10 is disposed in the cylinder 8 sealed by the seal body 14 described above, and the piston rod 12 extends through the seal body 14, and its extension end is for the continuous transfer described later. It is connected to a drive mechanism 28 (see FIG. 2) of the pump device. In this case, the piston 10 can be reciprocated (vertically moved) along the cylinder 8 by reciprocating (vertically moving) the piston rod 12 by the drive mechanism 28.

  In this case, the piston 10 includes a spherical piston valve 10a, a hollow valve seat 10b, and a frame 10c for preventing the piston valve 10a from falling off. The piston valve 10a is seated on the valve seat 10b so that inflow and outflow are prevented. On the other hand, when the piston valve 10a is separated from the valve seat 10b, an inflow / outflow is possible.

  Further, an upper check valve 24 and a lower check valve 26 are provided on both sides of the piston 10 in the reciprocating (vertical) direction. In the present embodiment, as an example, the upper side check valve 24 is provided in the discharge pipe 16 connected to the cylinder 8, and the lower side check valve 26 is provided in the lower part of the cylinder 8. The upper side and lower side check valves 24 and 26 include spherical check balls 24a and 26a, hollow valve seats 24b and 26b, and frames 24c and 26c for preventing the check balls 24a and 26a from falling off. When the check balls 24a and 26a are seated on the valve seats 24b and 26b, the inflow / outflow state is disabled. On the other hand, the check balls 24a and 26a are separated from the valve seats 24b and 26b. Inflow / outflow is possible.

  Further, as a drive mechanism 28 for reciprocating (up-and-down movement) of the piston 10, FIG. 2 shows a configuration for converting rotational motion into linear reciprocating motion and transmitting it to the piston rod 12. That is, the drive mechanism 28 includes a rotating plate 30 that is rotationally controlled by a motor (not shown), and a conversion rod 32 that converts the rotational motion of the rotating plate 30 into a linear motion. The conversion rod 32 has one end 32a. The other end 32 b is rotatably connected to the extending end of the piston rod 12 while being rotatably connected to one point in the circumferential direction of the rotating plate 30.

  In the drive mechanism 28, when the rotating plate 30 is rotated by the motor, the conversion rod 32 is turned along with the rotating motion at this time, so that the rotating motion of the rotating plate 30 is converted into a linear reciprocating motion via the converting rod 32. It is converted and transmitted to the piston rod 12. Accordingly, the piston 10 can be reciprocated (vertically moved) along the cylinder 8 by reciprocating (vertically moving) the piston rod 12.

  As shown in FIG. 3, in the continuous transfer pump device of this embodiment, in the above-described staying pipe structure 2, granular fish eggs (transfer objects) are accommodated together with a liquid (1 to 5% saline). The inner diameter W1 of the pipe 2t and the inner diameter W2 of the pump structure 4 that pumps the granular fish eggs (transfer object) together with the liquid (1 to 5% saline) (that is, the cylinder 8 described above) are W1. It is set to satisfy the relationship <W2.

  That is, one of the gist according to the technical idea of the present invention is that the inner diameter W1 of the staying pipe structure 2 (pipe 2t) is set smaller than the inner diameter W2 of the cylinder 8, and specifically, W2 is set to 100. In the case of%, W1 is set in a range of 40% to 70%. Here, W1 is preferably set in a range of 50% to 65%, and the best mode may be set to 63%.

  In addition, the height dimension T of the staying pipe structure 2 (pipe 2t), in other words, the depth dimension T from the concentration adjusting mechanism 6 (concentration adjusting container 6a) toward the lower side, or another way of understanding, the piston pump 4p ( Regarding the depth dimension T from the cylinder lower part of the cylinder 8) to the lower part side and the length dimension L of the staying pipe structure 2 (pipe 2t), the purpose and environment of use of the continuous transfer pump device, or Since it is set according to the size and shape of the installation place, there is no particular numerical limitation.

Next, operation | movement of the pump apparatus for continuous transfer of this embodiment is demonstrated.
When the piston 10 is moved upward (in the direction of the arrow S1 in FIG. 3) by the drive mechanism 28, the piston valve 10a of the piston 10 is seated on the valve seat 10b and becomes inflow / outflow impossible state. At the same time, a suction force acts on the lower side and a pressing force acts on the upper side.

  At this time, the lower side check valve 26 provided at the lower part of the cylinder 8 is in a state where the check ball 26a is separated from the valve seat 26b so as to be able to flow in and out. As a result, the stay pipe structure 2 (pipe) 2t) is kept together with the liquid and stays in the fish egg while being pumped together with the liquid while maintaining a high content ratio with respect to the liquid, passes through the lower check valve 26, and enters the cylinder 8 (piston 10 on the lower side).

  At the same time, the upper check valve 24 provided in the discharge pipe 16 becomes inflow / outflow state when the check ball 24a is separated from the valve seat 24b, and as a result, in the cylinder 8 (upper side of the piston 10). The fish eggs already contained in () are pushed out together with the liquid while maintaining a state in which the content ratio with respect to the liquid is increased, and after passing through the upper-side check valve 24, the fish egg (see FIG. 1) and is continuously transferred toward a predetermined seasoning apparatus.

  On the other hand, when the piston 10 is moved downward (in the direction of arrow S2 in FIG. 3) by the drive mechanism 28, the piston valve 10a of the piston 10 is separated from the valve seat 10b to be in an inflow / outflow state. As a result, the pressure does not act on the lower side and the upper side of the piston 10, and as a result, both the upper and lower check valves 24 and 26 have the check balls 24a and 26a seated on the valve seats 24b and 26b. By doing so, inflow and outflow are impossible.

  At this time, the fish eggs already contained in the cylinder 8 pass through the piston valve 10a together with the liquid while maintaining a state in which the content ratio to the liquid is increased, and then the upper side of the piston 10 in the cylinder 8 Moved to. Thereafter, similarly to the above, the piston 10 is moved upward (in the direction of arrow S1 in FIG. 3) by the drive mechanism 28, so that the fish eggs in the cylinder 8 (on the upper side of the piston 10) are moved together with the liquid to a predetermined level. It can be continuously transferred toward the seasoning apparatus.

  As described above, according to the present embodiment, the retention pipe structure 2 (pipe 2t) is provided on the lower side of the pump structure 4, and granular fish eggs (transfer objects) are concentrated at a high concentration in the retention pipe structure 2 (pipe 2t). The granular fish eggs (objects to be transferred) can be continuously transferred with a small amount of water by accommodating and retaining them in a state. As a result, granular fish eggs (transfer objects) can be efficiently and continuously transferred and supplied to a device that performs fish egg washing and separation processing on a large amount of fish eggs at a time. It is possible to dramatically improve the separation and cleaning efficiency of the concentration-transferred fish eggs.

  Further, according to the present embodiment, excessive external force (pressing force, water pressure, etc.) does not act on the granular fish egg (transfer object), thereby breaking (breaking or scratching) the egg. Yield can be drastically increased because the material can be continuously transferred without being attached).

  Furthermore, according to this embodiment, the staying pipe structure 2 (pipe 2t), the cylinder 8, the discharge pipe 16, the joining pipe 18, the delivery pipe 20, and the cover pipe 22 are connected and disassembled via the connector G. Since it is easy, maintenance and cleaning can be easily performed frequently or regularly. Thereby, the part (for example, the staying pipe structure 2 (pipe 2t), the cylinder 8, the discharge pipe 16, the merge pipe 18, and the delivery pipe 20) where particularly high hygiene is required is always kept clean and clean. Can do.

  Further, according to the present embodiment, when a plurality of piston pumps 4p are used as the pump structure 4, pumping transfer (delivery) in each piston pump 4p is performed by alternately operating adjacent piston pumps 4p by the drive mechanism 28. ) It is preferable to carry out processing alternately. As a result, the pulsation phenomenon (vibration, rattling, etc.) that occurs when a plurality of piston pumps 4p are simultaneously operated can be reduced. It becomes possible to continue using it stably.

  Here, for example, assuming a case where two piston pumps 4p are used (see FIG. 1), the drive mechanism 28 shown in FIG. In other words, one end 32a of the pair of conversion rods 32 may be connected to a position that is 180 degrees out of phase, and the other end 32b may be connected to the extending end of the piston rod 12 of each pump 4p.

  As a result, the pair of conversion rods 32 turn with a relative phase shift of 180 ° with the rotational movement of the pair of rotating plates 30. At this time, the pair of piston rods 12 are alternately (staggered) linearly. It will reciprocate. Thereby, since the pistons 10 in the two piston pumps 4p can be reciprocated (up and down) alternately (staggered), the pumping transfer (sending) process in the piston pumps 4p can be alternately performed.
