Description

High-pressure booster pump and shell separation device using the same {A shell separation device using a high-pressure booster pump}

The present invention relates to a high-pressure booster pump and a shell separation device, and more specifically, to a high-pressure booster pump capable of quickly generating and supplying high-pressure water, and to removing scallops or kernels from shells of shellfish using the high-pressure water pressure supplied using the same. It relates to a shell separation device using a high-pressure booster pump that can quickly separate.

Shellfish such as clams, oysters, and scallops are difficult to clean and take a lot of time due to their hard shells.

It is usually supplied with the shell, but recently, the supply with the shell removed and prepared has been increasing.

Conventionally, all work to remove shells and separate only the kernels of shellfish was done manually. So, workers picked up a peeling tool and removed the peels one by one. Of course, it took a lot of time and money, and it had the disadvantage that only skilled people could do it.

To improve this, Patent No. 10-1352724 below refers to a "shell support part that supports one of the two shells of an oyster; a liquid nitrogen cooling fluid is sprayed on the outer surface of the other shell for 1 second or more and 5 seconds or less to cool the oyster shell. A shell cooling unit that sterilizes and rapidly cools the corpus callosum within the shell; provided at the rear of the shell cooling unit, which heats the outer surface of the other shell to remove the corpus callosum attached to the inner surface of the other shell and removes the corpuscles from the ends of both shells. A shell heating unit that separates the shell; and a shell separation unit that separates the other shell by holding and rotating the spaced end of the other shell. The shell heating unit includes a bar with a sharp end. It is formed in a shape, and the portion where the crown is attached among the outer surfaces of the other shell is cut by rotation to reduce the shell thickness, and a rotating heating bar that conducts heat directly through contact is wound around the outer peripheral surface of the rotating heating bar, An oyster shell angle removal device, characterized in that it includes a heater coil that generates heat in the rotating heating bar, was presented.

This technology has the effect of reducing the processing cost of raw oysters, improving processing speed, and preserving the shape of raw oysters to some extent.

However, the equipment for supporting the shell, nitrogen cooling, heating, and means to rotate and separate the shell are complex, and there is the inconvenience of having to go through multiple processes.

Also, when fixing the shell to prevent it from moving, it was difficult to fix it because the shell's shape and size were all different.

Additionally, the shape of the separated oysters is not consistent and there is a risk of damage.

Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the attached drawings. 1 is a cross-sectional view showing a high pressure booster pump according to an embodiment of the present invention.

The high-pressure booster pump 300 according to the present invention is configured to increase water pressure by supplying water to a high-pressure sealed container 200, which will be described later. Referring to the figure, the double-acting hydraulic cylinder unit 310 and the hydraulic cylinder unit 320 ) can be implemented.

The double-acting hydraulic cylinder unit 310 is a configuration that alternately supplies hydraulic force to the hydraulic cylinder unit 320 on both sides by hydraulic pressure supplied from the outside. Specifically, the hydraulic operation chamber 311 and the hydraulic piston. (312) and may be composed of a pressure transmission rod (313).

The hydraulic operation chamber 311 is a space where hydraulic force is generated as hydraulic pressure is suctioned and discharged. The hydraulic operation chamber 311 has a cylindrical shape, and a first flow path 314a and a second flow path 314b through which hydraulic pressure is suctioned or discharged are formed on both sides, respectively.

And the hydraulic piston 312 is installed inside the hydraulic operation chamber 311.

The hydraulic piston 312 can reciprocate and slide along the longitudinal direction of the hydraulic operation chamber 311.

That is, when hydraulic pressure is sucked in through the first passage 314a, the hydraulic piston 312 moves toward the second passage 314b, and hydraulic pressure is discharged through the second passage 314b.

Conversely, when hydraulic pressure is sucked in through the second passage 314b, the hydraulic piston 312 moves toward the first passage 314a, and operates in such a way that hydraulic pressure is discharged through the first passage 314a.

Of course, the supply and recovery operations of hydraulic pressure may be controlled by a separate hydraulic circuit, although not shown.

The pressure transmission rod 313 is a rod vertically coupled to both sides of the hydraulic piston 312, has a rod shape, and is connected in the longitudinal direction of the hydraulic operation chamber 311.

Here, the pressure transmission rod 313 has a sufficient length and penetrates both ends of the hydraulic operation chamber 311, respectively, to be exposed to the outside. The ends of the pressure transmission rods 313 exposed in this way are introduced into the hydraulic operation chamber 321 of the hydraulic cylinder unit 320, which will be described later.

Accordingly, as the hydraulic piston 312 reciprocates, the pressure transmission rods 313 also reciprocate within the hydraulic operation chamber 321.

Preferably, a pair of limit sensors 311a for detecting the position of the hydraulic piston 312 are provided at both ends of the outer peripheral surface of the hydraulic operation chamber 311 to appropriately control the reciprocating movement of the hydraulic piston 312. You can.

Next, the hydraulic cylinder unit 320 supplies water to the high pressure sealed container 200 using the hydraulic force generated by the double-acting hydraulic cylinder unit 310 to increase the hydraulic pressure. It may be configured to include an operating chamber 321, packing 322, and a capping member 323.

The hydraulic operation chamber 321 is a space where water pressure is generated as water is suctioned and discharged. The hydraulic operation chamber 321 has a cylindrical shape and is coupled to both sides of the hydraulic operation chamber 311, respectively.

The hydraulic operation chamber 321 may be directly coupled to the hydraulic operation chamber 311, but as shown, an adapter 314 may be used to seal the hydraulic operation chamber 311. At this time, the first flow path 314a and the second flow path 314b may be formed in the adapter 314, respectively.

A hydraulic pressure forming hole 321a corresponding to the outer diameter of the pressure transmission rod 313 is formed inside the hydraulic operation chamber 321, so that the pressure transmission rod 313 can slide back and forth along the longitudinal direction.

And the packing 322 is attached and coupled to the outer peripheral surface of the pressure transmission rod 313. The packing 322 is strongly adhered to the inner peripheral surface of the hydraulic operation chamber 321 to prevent loss of hydraulic pressure.

On the other side of the hydraulic operation chamber 321, an inlet and outlet 323a through which water flows in and out is formed.

Preferably, as shown, a separate capping member 323 is coupled to the other side of the hydraulic operation chamber 321, and the inlet and outlet 323a may be formed in the capping member 323.

The inlet/outlet 323a is connected to the water tank 100 and the suction pipe 410, and is connected to the high pressure sealed container 200 and the extrusion pipe 510.

More preferably, a spring 324 and a collar 325 may be further provided inside the hydraulic operation chamber 321.

The spring 324 is a coil spring, and is provided on one side of the water pressure forming hole 321a of the water pressure operation chamber 321, that is, on the side opposite to the packing 322. And the collar 325 has a ring shape and is located between the spring 324 and the packing 322.

The inner diameter of the spring 324 and the collar 325 is formed to be larger than the outer diameter of the pressure transmission rod 313, so that when the pressure transmission rod 313 reciprocates, it penetrates the inside of the collar 325 and the spring 324. can do.

The packing 322 may be separated from the pressure transmission rod 313 due to the continuous reciprocating motion of the pressure transmission rod 313. The spring 324 and the collar 325 are provided, so that the spring 324 ) and the collar 325 blocks the movement of the packing 322 and prevents the packing 322 from being separated from the pressure transfer rod 313.

Meanwhile, the inner wall thickness of the hydraulic operation chamber 321 is preferably formed to be relatively thicker than the inner wall thickness of the hydraulic operation chamber 311.

For example, since a large pressure is applied to the hydraulic operation chamber 321, it may be more than twice the thickness of the inner wall of the hydraulic operation chamber 311, and is preferably 1.5 times more than the inner diameter of the hydraulic pressure forming hole 321a. .

And it is desirable that the outer diameter of the hydraulic piston 312 is formed to be three times or more than the outer diameter of the pressure transmission rod 313. The hydraulic force generated from the hydraulic piston 312 can be converted to a high pressure of three times or more as the cross-sectional area of the pressure transmission rod 313 is reduced.

Hereinafter, a shell separation device using a high pressure booster pump according to another embodiment of the present invention will be described with reference to FIG. 2. Figure 2 is a configuration diagram showing the overall structure of the shell separation device using the high pressure booster pump shown in Figure 1.

Referring to the figure, another embodiment of the present invention largely includes a water tank 100, a high pressure sealed container 200, a high pressure booster pump 300, a suction check valve 400, and an extrusion check valve 500. This can be implemented.

First, the water tank 100 may correspond to a tank or water tank in which water that provides water pressure is stored.

The water tank 100 may be provided as one, but may be provided as two, respectively connected to both ends of the high pressure booster pump 300.

Next, the high-pressure sealed container will be described with reference to FIG. 3. Figure 3 is a cross-sectional view showing the interior of the high-pressure sealed container of the present invention shown in Figure 2.

The high-pressure sealed container 200 is a container whose interior can be completely sealed and a receiving space is formed.

And the high-pressure sealed container 200 must be designed to have materials and properties that can withstand high pressure.

Specifically, it may be composed of a cylindrical housing 210 and a cover 220 that closes to seal both ends. In addition, a carrier 230 in the shape of a sieve or net may be further provided to prevent shellfish from scattering when placed inside.

The cover 220 is connected to both ends of the high pressure booster pump 300 and an extrusion pipe 510, so that water extruded from the high pressure booster pump 300 can flow into the high pressure sealed container 200.

Next, since the high pressure booster pump 300 is substantially the same as what was described above, detailed description will be omitted.

Next, the suction check valve 400 and the extrusion check valve 500 will be described.

The suction check valve 400 is installed on the suction pipe 410 and controls the water to flow from the water tank 100 only to the hydraulic operation chamber 321 when water is sucked from the hydraulic operation chamber 321. do.

The extrusion check valve 500 is installed on the extrusion pipe 510 so that when water is extruded into the high pressure sealed container 200, it flows only from the water pressure operation chamber 321 to the high pressure sealed container 200. Control.

Below, the operating process of the present invention will be briefly described with reference to FIG. 4. Figure 4 is a diagram showing the operating state of the present invention.

First, a case in which the hydraulic piston 312 moves from left to right will be described with reference to FIG. 4A.

When hydraulic pressure is supplied to the hydraulic operation chamber 311 through the first flow path 314a, the hydraulic piston 312 moves to the right, and the hydraulic pressure on the right side of the hydraulic piston 312 is transferred to the second flow path ( It is discharged through 314b).

As a result, the pressure transmission rod 313 coupled to the right side of the hydraulic piston 312 also moves to the right to push and extrude the water filled in the hydraulic operation chamber 321, and the extruded water is sent to the extrusion pipe 510. It is forcibly pressed into the right side of the high pressure sealed container 200.

At this time, the suction check valve 400 blocks the extruded water from flowing back into the water tank 100. Accordingly, the internal water pressure increases due to the water pressurized into the high-pressure sealed container 200.

Meanwhile, as the pressure transmission rod 313 coupled to the left side of the hydraulic piston 312 moves to the right, negative pressure is applied inside the hydraulic operation chamber 321 and water is sucked from the water tank 100, thereby causing the hydraulic operation. Water fills the room 321.

At this time, the extrusion check valve 500 blocks the sucked water from flowing into the high pressure sealed container 200.

Conversely, a case in which the hydraulic piston 312 moves from right to left will be described with reference to FIG. 4B.

When hydraulic pressure is supplied to the hydraulic operation chamber 311 through the second flow path 314b, the hydraulic piston 312 moves to the left, and the hydraulic pressure on the left side of the hydraulic piston 312 is transferred to the first flow path ( It is discharged through 314a).

As a result, the pressure transmission rod 313 coupled to the left side of the hydraulic piston 312 also moves to the left to push and extrude the water filled in the hydraulic operation chamber 321, and the extruded water is moved to the extrusion pipe 510. It is forcibly pressed into the left side of the high pressure sealed container 200.

At this time, the suction check valve 400 blocks the extruded water from flowing back into the water tank 100. Accordingly, the internal water pressure rises again due to the water pressured into the high-pressure sealed container 200.

Meanwhile, as the pressure transmission rod 313 coupled to the right side of the hydraulic piston 312 moves to the left, negative pressure is applied inside the hydraulic operation chamber 321, and water is sucked from the water tank 100, thereby causing the hydraulic operation. Water fills the room 321.

At this time, the extrusion check valve 500 blocks the sucked water from flowing into the high pressure sealed container 200.

By repeating this process, the water pressure inside the high-pressure sealed container 200 is set to approximately 4000 to 6000 bar, and when high-pressure treatment is performed in this state for about 1 to 2 minutes, the tube can be separated from the shell.

To explain further, the water pressure flowing into the inside of the shell causes the shell to open, and as the water pressure flows along the inner curved surface of the shell, pressure acts around the temple attached to the inner surface of the shell, causing the temple to open. As it tightens, the volume decreases.

On the other hand, when the volume of the temple is reduced, the volume of the shell does not change, so the adhesive area of the soft temple attached to the inner surface of the shell is reduced, and the temple is separated from the shell.

Although the present invention has been described with reference to the drawings according to embodiments of the present invention, those skilled in the art will be able to make various applications and modifications within the scope of the present invention based on the above contents.
