EXTRUSION PUMPING MODULE AND DIAPHRAGM FLUID SUPPLY

DEVICE USING THE SAME [Technical Field]

The present invention relates to an extrusion pumping module and a diaphragm fluid supply device using the same, which allows a pumping module formed of a metal material to compress and expand an internal space without physically interfering with each other, prevents damage or breakage from occurring easily even under the influence of repetitive external force, and has additional elastic regions, thereby obtaining a stronger extrusion effect.

[Background Art]

Generally, a pump for transporting a stored liquid or gas to a predetermined place has been widely used.

The pump is a device that transports liquid or gaseous fluid through a pipe by a pressure action, or presstransfers fluid to a predetermined direction.

At this time, the pressure for transferring the fluid may be generated in various ways.

The pump is used in various ways depending on a method for generating pressure thereof, including a reciprocating pump using a piston or a plunger, a rotary pump that converts a rotational force into a linear motion to reciprocate a piston, a centrifugal pump that increases and transfers the pressure of a liquid to the impellers, an axial pump that allows the propeller to rotate and flow a liquid to one direction, and the like.

Page 1

The various types of pumps as described above are utilized appropriately in accordance with the characteristic of each pump depending on their using industry.

Korean Patent No. 10-1116054 'Diaphragm valve' has disclosed a technique for extruding paint to utilize it in painting among various aspects of a pump.

Specifically, a configuration that as an internal space of a corrugated pipe member formed of metal is expanded, paint is introduced therein and as the internal space of the corrugated pipe member is compressed to extrude the paint to an outside has been disclosed, and through this configuration it can double the durability and increase the pressure for extruding the paint.

However, the technique described above had a disadvantage that since the corrugated pipe member which is contracted and expanded repeatedly is formed of metal, a strong discharge pressure is obtained due to the nature of the metal, but the amount of the paint discharged per unit time is relatively small.

In addition, there was a disadvantage that a fatigue breakage due to repeated contraction and expansion is most likely to occur and thus results in a short lifespan, and there was also a problem that a wider area should be more closely coupled by welding in order to prevent breakage of the corrugated pipe member.

Therefore, a method for solving such problems is required.

[Best Mode]

Hereinafter, preferred embodiments of the present invention in which the object thereof can be specifically realized will be described in detail with reference to the accompanying drawings. Such terms as the top (upper), below (lower), right and left (side or sideward), front (fore, forward), back (rear, rearward) for designating direction in the description and the claims of the invention are used for convenience of explanation, not for the purpose of limiting the rights, and are based on the relative positions between the drawings and the configurations, and respective directions described below are based on them except where otherwise specifically limited.

The extrusion pumping module according to the present invention may be implemented as follows.

As shown in FIGS. 3 to 5, the extrusion pumping module according to the first embodiment of the present invention may be implemented by coupling a plurality of pumping units 300 .

Page 9

The pumping unit 300 includes a plate member 310 in a plate shape, at a center of which a flow hole 314 opened is provided and which is formed to be inclined gradually to one outer side with respect to the flow hole, a coupling member 330 provided so that a pair of the plate members 310 overlap so as to form a space in the inside and the outer circumferences of the pair of plate members 310 are mutually fastened, and a sealing member 320 included between the coupling member 330 and the pair of plate members 310 to perform buffering and sealing.

In the pumping unit 3 00, as a gap between the pair of plate members 310 is narrowed, the accommodated material accommodated in the inside may be extruded through the flow hole 314, and as the gap between the pair of plate members 310 is distanced, a space on the inner side is widened so that the accommodated material may be introduced.

In addition, the plurality of pumping units 300 is coupled to constitute a pumping module 30 so that flow holes communicate with each other.

Each of the above-described configurations will be described in detail below.

The pumping unit 300 is formed by overlapping a pair of plate members 310, and a space is formed therein.

The space formed inside the pumping unit 300 is exposed to the outside through the flow hole 314 provided in the pair of plate members 310, which are coupled to each other.

Since the pair of plate members 310 are coupled to each other along the outer circumferences thereof, two flow holes 314 are included in one pumping unit 300 and each of the two flow holes 314 may be disposed on the opposite side, respectively.

The unit plate member 310, that is, one plate member 310 is a plate-shaped member at a center of which the flow

Page 10 hole 314 is formed through and has a constant inclination toward the outer side with respect to the flow hole 314.

Therefore, one surface of the plate member 310 protrudes in a convex shape, and the other surface is sunk

in a concave shape as shown in FIG. 3.
When the pair	of	plate members 310	are coupled to each
other adjacently	to	their	outer circumferences,	their
concave surfaces	are	opposed	to each	other, and	thus a

predetermined space may be formed on the inside of the pumping unit 300 in which the pair of plate members 310 are coupled.

Each of the plate members 310 may be formed in the form of a disk, at the center of which the flow hole 314 is formed through. The plate member 310 may have various shapes such as a disk shape, a rectangular plate shape, etc. according to an embodiment to which the present invention is applied. An embodiment of the present invention will be described as an example in the case of a disk shape.

The plate member 310 in an embodiment of the present invention may be formed of a metal material having elasticity and thus is deformed by an external force, which may be implemented with a material having a property of restoring to its original shape when the external force is removed.

Further, the plate member 310 may further include a first elastic section 312 between the flow hole 314 and the outer circumference thereof, which surrounds continuously the flow hole 314 with a predetermined width.

The first elastic section 312 may have smaller elastic coefficient than that of the material of the plate member 310 such that it may be deformed flexibly due to the external force.

In more detail, the first elastic section 312 may be formed by a part of the plate member 310 being corrugated,

Page 11 and as shown in FIGS. 3 to 5, the first elastic section may be disposed on an outside of the flow hole 314 with respect to the center of the flow hole 314 of the plate member 310, thereby forming a closed line surrounding the flow hole 314.

The reason why the first elastic section 312 is formed in the form of corrugation is that a part of the plate member 310 is provided to be corrugated such that the plate member may be more flexibly deformed to the external force and higher pressure is applied to the internal accommodated material of the pumping unit 3 00 and the pumping module 3 0 formed by the plate members 310 being coupled and further the amount of the accommodated material to be extruded through much volume change of the accommodated material per unit time is increased.

As another example, the first elastic section 312 may be made of the metal material having the same elastic coefficient as that of the plate member 310 wherein the relative thickness becomes thicker gradually toward the flow hole 314 and the outer circumference of the plate member and becomes thinner gradually toward the flow hole 314 and the middle end between the outer circumferences.

At this time, the first elastic section has a relatively thinner thickness and is deformed flexibly to the external force and thus it can conclusively obtain the same effects as the case where it has low elastic coefficient.

The outer circumference of the plate member 310 may be processed to be folded in the convex surface along the circumference and the coupling member 330 may be fastened around the outer surface of the folded portion.

The coupling member 330 is disposed around the outer circumferences of the pair of plate members 310 facing each other and is fastened around the outer circumferences of the folded part through the fastener 340.

Page 12

A plurality of the fastener 340 may be fastened at a predetermined distance, passing through each of the pair of plate members 310 and the coupling member 330.

Further, the sealing member 320 may be inserted between the plate member 310 and the coupling member 330 to be fastened together through the fastener 340.

The sealing member 320 is disposed continuously along the outer circumference of the plate member 310 and performs buffering and sealing functions between the plate member 310 and the coupling member 330.

The sealing member 320 is implemented as a spacer for performing a buffering function and a sealing member for performing a sealing function and further may be configured in various ways for buffering and sealing according to the embodiment to which the present invention is applied.

The coupling member 33 0 is a thin plate member and has a long length enough to enclose the entire outer circumference of the plate member 310.

According to an embodiment of the present invention, the coupling member 330 also may be made of metal material.

Further, the coupling member 330 may further include a second elastic section 332 which is formed to be long continuously from a middle end of the up and down direction to the left and right direction, assuming that the length direction is a left and right direction.

The second elastic section 332 may be implemented to have lower elastic coefficient than the intrinsic elastic coefficient of the coupling member 330, as in the first elastic section 312.

The second elastic section may be configured to have a thinner thickness than the surroundings, as shown in FIGS. 6 and 7, a part of the surface of which is processed to be folded protruding toward one surface.

Page 13

At this time, the coupling member 330 which is coupled around the outer circumference of the pair of plate members 310 may be coupled such that a part of the second elastic section 332 which is folded-processed protruding is inserted into between the outer circumferences of the plate member to be coupled each other, without at least some interference.

As another example, the coupling member 330 may be bond-processed by enclosing the outer circumferences of the pair of plate member 310.

The bond-process may utilize a welding for boding metal material by heating and melting and a welding with pressure for applying a strong physical pressure, and various ways may be implemented according to the embodiment to which the present invention is applied.

Further, the first elastic section 312 of the plate member 310 as described above, as shown in FIG. 8, may be provided on the entire region of the plate member 310 not on a part thereof wherein it may be decided whether the first elastic section is provided on the entire region or a part thereof according to the embodiments to which the present invention is applied.

The volume of the internal space provided inside the pumping module 30 can be varied flexibly in response to the external force while the pumping module 30 is compressed or expanded and this effect contributes to increase the amount of the accommodated material to be pumped per unit time.

As shown in FIGS. 9 to 13, the extrusion pumping module according to the second embodiment of the present invention may be implemented by coupling a plurality of pumping units 300 .

Page 14

The pumping unit 300 includes a plate member 310 in a plate shape, at a center of which a flow hole 314 opened is provided and which is formed to be inclined gradually to one outer side with respect to the flow hole 314, and a pair of the plate members 310 overlaps so as to form a space in the inside and the outer circumferences of the pair of plate members 310 are mutually fastened.

At this time, the plate member 310 includes a first elastic section 312 which is curved to one side between the flow hole 314 and the outer circumference, and in the pumping unit 300, as a gap between the pair of plate members 310 is narrowed, the accommodated material accommodated in the inside is extruded through the flow hole 314, and as the gap between the pair of plate members 310 is distanced, the accommodated material is introduced to a space on the inner side is widened so that, and the plurality of pumping units 300 may be coupled so that flow holes communicate with each other .

Each of the above-described configurations will be described in detail below.

The space formed inside the pumping unit 300 is exposed to the outside through the flow hole 314 provided in each of the pair of plate members 310 which are coupled to each other .

The unit plate member 310, that is, one plate member 310 is a plate-shaped member, at a center of which the flow hole 314 is formed with a through hole and has a constant

Page 15 inclination toward the outer side with respect to the flow hole 314.

Therefore, one surface of the plate member 310 protrudes in a convex shape, and the other surface is sunk in a concave shape as shown in FIG. 9.

When the pair of plate members 310 are coupled to each other adjacently to their outer circumferences, their concave surfaces are faced to each other, and thus a predetermined space may be formed on the inside of the pumping unit 300 in which the pair of plate members 310 are coupled.

As shown in FIG. 9, a coupling part 316 may be provided on the outer circumference of the plate member 310 for coupling to an additional plate member 310.

The coupling parts 316 of the plate member 310 are coupled through a bonding process, and as shown in FIG. 11, they may be coupled through a separate fastener 340, and at this time a plurality of fasteners 340 may be coupled to the coupling parts 316 constituting the outer circumference of the plate member 310 at a predetermined distance.

Each plate member 310 may be formed in the form of a disk of a through hole, at the center of which the flow hole 314 is formed. The plate member 310 may have various shapes such as a disk shape, a rectangular plate shape, etc., and it may be a polygonal shape or a circular shape corresponding to the shape of the flow hole 314 and the shape of the outer circumference of the plate member 310 according to an embodiment to which the present invention is applied. However, an embodiment of the present invention will be described as an example in the case of a disk shape.

The plate member 310 in an embodiment of the present invention may be formed of a metal material having elasticity and thus is deformed by an external force, which can be implemented with a material having a property of

Page 16 restoring to its original shape when the external force is removed.

As shown in FIG. 9, the plate member 310 may further include an elastic section 312 on an inner side adjacent to the coupling part 316, which is formed by enclosing the plate member 310.

The elastic section 312 may be curved outwardly each

other	in	a semi-circular shape	in	the	pumping	unit	3 00 in
which	a	pair of plate members	310	are	coupled,	and	as	the
interval	between the plate members	310	coupled	facing	each

other is varied, the external force applied to the coupling part 316 is reduced due to the continuously curved shape of the elastic section and further additional flexibility in changing the interval between the plate members 310 is given.

The elastic section 312 has smaller elastic coefficient than that of the material itself of the plate member 310 such that it may be deformed more flexibly to the external force .

Through this configuration the amount of the accommodated material to be extruded can be increased through much volume change of the accommodated material per unit time while applying higher pressure to the accommodated material within the pumping unit 300 and the pumping module 30 formed by coupling the plate members 310.

The outer circumferences of the plate members 310, that is, the coupling parts 316 are disposed, one face of which

is	in contact with each other, and a	coupling member	330	may
be	further	included	to be coupled	such	that it	can	be
compressed	on both	sides of each	outer	surface	by	the

external force.

As shown in FIG. 14, the coupling member 33 0 has a predetermined length and is provided to surround an outer side of the coupling part 316 of the plate members 310 disposed facing each other and is coupled through a fastener

Page 17

340 to compress both surfaces of the coupling part 316 to provide fixing force, and at this time the fastener 340 passes through all of the coupling member 330 and the coupling part 316 to couple firmly the pair of plate members 310 disposed facing each other.

As described above, a plurality of pumping units 300 are coupled to constitute the pumping module 30.

The pumping module 3 0 is disposed such that the flow holes 314 of each pumping unit 300 included communicate with each other and adjacent pumping units are coupled to each other .

As shown in FIGS. 10 and 12, the coupling member 330 as described above may be implemented identically even at a coupling portion of the pumping units 300, and when the pumping units 300 are coupled facing to each flow hole 314, the elastic section 312 may be further disposed adjacently to the flow hole 314.

In more detail, as shown in FIG. 13, the elastic section 312 provided on the pumping unit 3 00 is disposed adjacently to the coupling part 316 and further may be further provided even on a region adjacent to the flow hole 314. Through this configuration the volume of the internal space can be varied flexibly in response to the external force while the volume of the internal space is varied during compression and expansion of the pumping module 30, and the amount of the accommodated material to be pumped per unit time can be increased.

The diaphragm fluid supply device according to the present invention will be implemented as follows.

As described above, a plurality of pumping units 300 are coupled, the pumping module 3 0 in which the flow holes 314 of each pumping unit 300 are provided so as to communicate with each other is included, and a casing 10 is included, in which an operating shaft 20 which is disposed

The operating shaft 20 reciprocates along its length direction to contract or expand the volume of the internal space of the pumping module 30.

At this time, the pumping module 3 0 is contracted or expanded in response to the external force while a plurality of pumping units 300 constituting the pumping module 30 and a plurality of plate members 310 and coupling members 330 constituting the pumping unit 300 are coupled, respectively.

The diaphragm fluid supply device according to the present invention is shaped wholly as a corrugated pipe to be contracted and expanded.

The reciprocating movement of the operating shaft 20 in a length direction may be performed repeatedly, the volume of the internal space of the pumping module 30 is increased according to the movement of the operating shaft 20, the pressure of the internal space of the pumping module 30 is drops abruptly such that the accommodated material is introduced through the inflow hole 12, the pressure of the internal space of the pumping module 30 is increased abruptly as the volume of the internal space of the pumping module 30 according to the movement of the operating shaft 20 such that the introduced accommodated material is
