Description

Technical Field

[0001] The present invention relates to a diaphragm pump that discharges one or more types of fluids through a plurality of discharge pipes. More specifically, the present invention relates to a diaphragm pump in which one diaphragm pump allows one or more types of fluids to flow in through diaphragm pumping, separates them into a plurality of fluids, and discharges each of them, and is provided with a plurality of discharge pipes capable of mixing the separated fluids according to the user's application to generate a mixed fluid.

Background Art

[0002] Generally, a pump is a typical fluid machine that receives energy transmission from an electric motor or the like and moves a fluid, and various types of pumps can be used depending on the purpose. At this time, the mainly used pump is a centrifugal pump, but such a centrifugal pump has the drawback that priming must be performed when operating.

[0003] Therefore, as types of pumps that can solve such problems, there are linkage pumps, diaphragm pumps, etc. Among these, a diaphragm pump can transfer a fluid by pumping a diaphragm such as elastic rubber.

[0004] As a prior art for such a diaphragm pump, it is disclosed in Korean Registered Patent Publication No. 10-1182477 as "Fluid Diaphragm Pump". Such prior art discloses a diaphragm pump that uses a motion conversion unit that receives rotational force from a motor and converts the rotation of a non-linear camshaft into a linear reciprocating motion to pump a diaphragm while sucking and discharging fluid into a pressure chamber.

[0005] On the other hand, in the case of a conventional diaphragm pump including the above prior art, since it has only one flow path through which only one fluid flows in and is discharged, it cannot suck and discharge a plurality of fluids, nor can it mix each discharged fluid to create and discharge a mixed fluid.

[0006] Furthermore, even when the same fluid is introduced, it is not possible to create and discharge multiple streams of water with different physical properties, such as discharge velocity.

[0007] Overcoming this requires the cumbersome requirement of equipping the system with a diaphragm pump capable of handling multiple discharge pipes.

[0008] Furthermore, the motion conversion unit that converts rotational motion into linear reciprocating motion uses a nonlinear camshaft, making it difficult to increase the rotational force of the motor. As a result, there is a problem in that it cannot push out fluid with very strong force. [Overview of the project] [Problems that the invention aims to solve]

[0009] The present invention aims to solve the aforementioned problems and provides a diaphragm pump equipped with multiple discharge pipes, in which one or more fluids are drawn in through the pumping of the diaphragm, separated and discharged from multiple discharge pipes, and the multiple fluids discharged can be controlled to become a mixed fluid as needed.

[0010] The problems that this invention aims to solve are not limited to those mentioned above, and any other problems not mentioned can be clearly understood by an ordinary person from the following description. [Means for solving the problem]

[0011] The present invention, which solves the aforementioned problems, provides a diaphragm pump equipped with multiple discharge pipes through which fluid is discharged,

[0012] It consists of a power housing that provides rotational force; a motion conversion unit that converts the rotational force transmitted through the power housing into linear reciprocating motion; and a pump housing that receives and discharges fluid using the linear reciprocating motion provided by the motion conversion unit.

[0014] A diaphragm pump is disclosed, which has a pump housing containing a first flow path connecting to a first intake valve, a first pressurizing chamber, a first discharge valve, and a first discharge pipe; and a second flow path connecting to a second intake valve, a second pressurizing chamber, a second discharge valve, and a second discharge pipe; and a plurality of discharge pipes forming two or more independent flow paths.

[0015] Furthermore, the power unit may include a reduction gear that increases torque.

[0016] Furthermore, the motion conversion unit can be constructed using a rotating housing with guide rails formed on it.

[0017] Furthermore, the rotating housing may include a frame to prevent detachment.

[0018] Furthermore, it may further include a nozzle housing that includes an outer nozzle and an inner nozzle.

[0019] Furthermore, the outer nozzle may be equipped with a mixing channel.

[0020] Furthermore, the inner nozzle may have numerous pores formed on its outer surface.

[0021] Furthermore, the inner nozzle may have one or more venturi discharge passages.

[0022] In addition, a vortex plate may be further formed between the inner nozzle and the outer nozzle.

[0023] In addition, one end of the nozzle housing may further include a brush head.

Advantages of the Invention

[0024] Thus, the present invention enables a single diaphragm pump to discharge a plurality of fluids respectively, and further has a plurality of nozzles that can select the type, amount, physical properties, etc. of each of the discharged fluids and mix them according to the application, so that it has effects such as being able to generate a variety of mixed fluids.

In this application, terms such as “includes” or “having” are intended to specify the presence of features, figures, stages, operations, components, parts, or combinations thereof described in the specification, and should be understood not to preemptively exclude the possibility of the presence or addition of one or more other features, figures, stages, operations, components, parts, or combinations thereof.

[0043] The embodiments of the present invention will now be described with reference to the attached drawings. The same reference numerals in each drawing indicate the same component. In describing the present invention, specific descriptions of related known functions or configurations will be omitted in order to avoid obscuring the gist of the invention.

[0044] The present invention relates to a diaphragm pump 1 equipped with a plurality of discharge pipes 331 and 332, each of which discharges an independent fluid.

[0045] The diaphragm pump 1 is a power housing 100 that provides rotational force;

[0046] A rotating housing 200 is a motion conversion unit that receives rotational force from the power housing 100 and converts rotational motion into linear reciprocating motion; and

[0047] It consists of a pump housing 300 having multiple independent flow paths that allow external fluid to flow into and discharge from the rotating housing 200 by linear reciprocating motion transmitted from the rotating housing 200.

[0048] The configuration of the diaphragm pump 1 according to the present invention will be explained through Figures 1 to 9.

[0049] Figure 1 shows the overall appearance of a diaphragm pump 1 according to the present invention, which has major components including a power housing 100; a rotating housing 200; and a pump housing 300; and a nozzle housing 400 that may be additionally connected to the pump housing 300.

[0050] Figure 2 shows the operation of the rotating housing 200 in the motion conversion unit, which converts the rotational motion provided by the power housing 100 shown in Figure 3 into linear reciprocating motion, and the rotating housing 200 pumps the diaphragm, which is the source of the force that moves the fluid in the diaphragm pump 1 of the present invention.

[0051] Figure 3 illustrates, with reference to Figure 2, how the power housing 100 and the rotary housing 200 work in conjunction to pump the diaphragms D1, D2, D3, D4, and D5 of the diaphragm frame 350, which are components of the pump housing 300.

[0052] The power housing 100 is located at one end of the diaphragm pump 1 and plays the role of providing rotational force so that the diaphragm pump 1 can perform its operation, and includes a power unit 110 that provides rotational force; a reduction unit 120 coupled to the power unit 110; and a power shaft 130 that exits the reduction unit 120 and is axially coupled to the rotating housing 200 by an axial coupling hole 211.

[0053] The power unit 110 typically uses a motor to rotate a power shaft 130 that protrudes from the center of one end of the power unit 110, thereby rotating a rotating housing 200 connected to the power shaft 130, and through this, it performs the role of operating the pump housing 300.

[0054] At this time, a reduction gear 120 is provided on the same axis as the power unit 110 in order to transmit a rotational force having a larger torque to the rotating housing 200 in addition to the rotational force provided by the power unit 110.

[0055] In Figure 2, the rotating housing 200, which is the motion conversion unit, consists of a rotating frame 210 that is connected to and rotates with the power housing 100; a support shaft 220 that performs linear reciprocating motion due to the rotation of the rotating frame 210; and a detour prevention frame 230 that prevents the support shaft 220 from deviating from its track.

[0056] First, the rotating frame 210 has a cylindrical shape and is curved along its outer surface, continuing to recess as it moves, forming a guide rail 212 that guides linear reciprocating motion by drawing in a bearing 221 formed at one end of the support shaft 220.

[0057] In other words, as the rotating frame 210 rotates, the bearing 221 moves along the inclined inner side of the bent guide rail 212, causing the support shaft 220 to perform linear reciprocating motion.

[0058] Furthermore, since the support shaft 220 moves in a linear reciprocating motion through an insertion groove 231 provided in the detachment prevention frame 230 which is fixed at a specific position, it is possible to prevent the support shaft 220 from detaching from the insertion groove 231.

[0059] Each diaphragm holder 223 is formed at the other end of the support shaft 220, which is connected to each diaphragm D1 and D2, and pumps the diaphragms D1 and D2.

[0060] In Figure 3, the pump housing 300, which has five pressurizing chambers P1, P2, P3, P4, and P5, is operated by pumping the five diaphragms D1, D2, D3, D4, and D5.

[0061] To briefly explain the operation of the pump housing 300 according to the present invention, we will describe two examples having two pressurizing chambers P1 and P2, but the same operating method will also be applied to various applications having three or more pressurizing chambers, including the conditions for independent flow paths described later.

[0062] As a first embodiment, a case in which a common inflow fluid F of one type is introduced externally and separated into two fluids F1 and F2 from two intake valves 341 and 342 and then discharged is explained through Figures 4a, 4b, and 4c.

[0063] As a second embodiment, a case in which two fluids F1 and F2 are introduced from the outside and discharged separately from the point of inflow is described with reference to Figures 5a, 5b, and 5c.

[0064] The configuration of the pump housing 300 in the first embodiment, which receives and separates a common inflow fluid F and discharges it as two fluids F1 and F2 respectively, is as follows:

[0065] As shown in Figure 4a, the pressurized frame 310 has holes drilled in the top and bottom of the cylindrical interior, and has two hollow pressurized chambers P1 and P2 of different sizes separated by a pressurized chamber separation wall 312;

[0066] A diaphragm frame 350 is in close contact with one surface of the pressurizing frame 310 and has two diaphragms D1 and D2;

[0067] A separation frame 340 is attached to the other side of the pressurized frame 310 and is equipped with two suction valves 341, 342 and two discharge valves 343, 344;

[0068] A lower frame 320 that is in close contact with the aforementioned separation frame 340, shares the aforementioned intake valves 341 and 342, and is equipped with an inlet pipe 321;

[0069] An upper frame 330 is provided, which is in close contact with the separation frame 340 and has two discharge pipes 331 and 332 that share the discharge valves 343 and 344.

[0070] In this way, each pressurized chamber P1 and P2 has an independent space separated by a diaphragm frame 350 and a separation frame 340, and each pressurized chamber P1 and P2 has one intake valve 341 and 342 and one discharge valve 343 and 344 that open in opposite directions to each other.

[0071] In these pressurized chambers P1 and P2, the internal pressure increases as the diaphragms D1 and D2 move downward, generating negative pressure as their internal volume increases, and decreases as they move upward, generating positive pressure as their internal volume decreases, thereby pushing out the fluid inside the chambers P1 and P2 and drawing in fluid from the outside.

[0072] This type of fluid flow is illustrated in Figure 4b,

[0073] When the internal pressure of pressurized chambers P1 and P2 becomes negative, the suction valves 341 and 342 located on the separation frame 340 open.

[0074] The common inflow fluid F stored in the lower frame 320 flows into the first pressurized chamber P1 through the opened first intake valve 341, and into the first fluid F1,

[0075] The common inflow fluid F stored in the lower frame 320 flows into the second pressurized chamber P2 through the opened second intake valve 342, and into the second fluid F2.

[0076] They will enter separately.

[0077] At this time, the internal pressure of the lower frame 320 also changes to a negative pressure, so the common inflow fluid F is drawn in from the outside through the inflow pipe 321 and stored in the lower frame 320.

[0078] At this time, the negative pressure causes the discharge valves 343 and 344 located on the separation frame 340 to close.

[0079] Conversely, when the internal pressure of pressurized chambers P1 and P2 changes to an increased pressure, it causes the discharge valves 343 and 344 located on the separation frame 340 to open.

[0080] The first fluid F1 stored in the first pressurized chamber P1 through the opened first discharge valve 343 enters the first discharge pipe 331.

[0081] The second fluid F2 stored in the second pressurizing chamber P2 through the opened second discharge valve 344 enters the second discharge pipe 332.

[0082] Each is pushed upward, causing the respective fluids F1 and F2 that were in the discharge pipes 331 and 332 to be discharged to the outside.

[0083] At this time, the added pressure causes the intake valves 341 and 342 located on the separation frame 340 to close.

[0084] In this process, where positive (+) pressure and negative (-) pressure are sequentially converted, the flow of the common inflow fluid F is as shown in Figure 4c.

[0085] The inlet pipe 321, the lower frame 320, the first intake valve 341, the first pressurizing chamber P1, the first discharge valve 343, and the first flow path R1 connected to the first discharge pipe 331;

[0086] A second flow path R2 is formed, which connects to the inlet pipe 321, the lower frame 320, the second suction valve 342, the second pressurizing chamber P2, the second discharge valve 344, and the second discharge pipe 332.

[0087] The common inflow fluid F that flows in in this manner flows into two independent channels R1 and R2, where the first fluid F1 and the second fluid F2 are separated after each suction valve 341 and 342 and do not mix until they are discharged into each discharge pipe 331 and 332.

[0088] The configuration of the pump housing 300 in the second embodiment, which receives two fluids F1 and F2 respectively and discharges them, is as follows:

[0089] As shown in Figure 5a, and compared with Figure 4a, it has the same structure except for the lower frame 320.

[0090] Using the same operating method, the pumping of diaphragms D1 and D2 alternately generates positive (+) and negative (-) pressure in each pressurized chamber P1 and P2, allowing the two fluids F1 and F2 to flow into and out of the pressurized chambers P1 and P2.

[0091] At this time, in order to separate the paths of the two incoming fluids F1 and F2 so that they do not mix with each other, the lower frame in Figure 5a is divided by a lower frame separation wall 322 to have two spaces: a first lower frame 320a and a second lower frame 320b.

[0092] Furthermore, the two lower frames 320a and 320b are each equipped with inlet pipes 321a and 321b corresponding to the inlets of the respective lower frames 320a and 320b.

[0093] Figure 5b shows that the pumping of diaphragms D1 and D2 causes the two fluids F1 and F2 to flow in the same manner from the two inlet pipes 321a and 321b to the two lower frames 320a and 320b, respectively, due to the negative (-) and positive (+) pressure generated in the pressurizing chambers P1 and P2. These fluids then flow into the pressurizing chambers P1 and P2 through the two suction valves 341 and 342, and are discharged into the two discharge pipes 331 and 332 through the two discharge valves 343 and 344, thus creating two independent flow paths in which the two fluids do not mix.

[0094] In this process, as the positive (+) pressure and negative (-) pressure are sequentially converted, the flow of the two fluids F1 and F2 is as shown in Figure 5c.

[0095] The first fluid F1 flows through the first flow path R1 connected to the inlet pipe 321a, the first lower frame 320a, the first suction valve 341, the first pressurizing chamber P1, the first discharge valve 343, and the first discharge pipe 331.

[0096] The second fluid F2 moves through the second flow path R2, which is connected to the inlet pipe 321b, the second lower frame 320b, the second suction valve 342, the second pressurizing chamber P2, the second discharge valve 344, and the second discharge pipe 332, respectively.

[0097] In the two embodiments described above, the amount of fluid discharged from the two discharge pipes 331 and 332 may vary depending on the volume of the corresponding pressurized chambers P1 and P2 formed in the two flow paths R1 and R2. With the use of the nozzle housing 400 described later, the same type of fluid may be discharged to the outside with extremely different physical properties, or it may be discharged as a completely mixed mixture of different fluids.

[0098] Furthermore, in extended applications with three or more pressurized chambers, the amount of fluid discharged from each discharge pipe may also be related to the number of pressurized chambers formed in each flow path.

[0099] Figures 4c and 5c show that the two fluids F1 and F2 have two independent flow paths R1 and R2 from the intake valves 341 and 342 until they are discharged from the discharge pipes 331 and 332.

[0100] Here, "independent flow channels" means that the fluids flowing through each channel do not mix. In the two embodiments described above, two separate flow channels R1 and R2 were formed from the intake valves 341 and 342 to the discharge pipes 331 and 332, ensuring that the fluids F1 and F2 do not mix.

[0101] In order to satisfy such independent flow channels,

[0102] First, the lower frame supplying the same fluid to pressurized chambers P1 and P2 is treated as a single lower frame space, even if it is formed separately.

[0103] Furthermore, each pressurized chamber must receive fluid through only one lower frame space and discharge fluid through only one discharge pipe.

[0104] Furthermore, if each discharge pipe is designed to receive fluid in one or more pressurized chambers to discharge a flow rate suitable for its application, multiple independent flow channels can be formed.

[0105] If a single pressurized chamber discharges fluid into two or more discharge pipes, it must be considered as a single flow path.

[0106] The aforementioned operating method should also be applied to pump housings 300 that move three or more types of fluids or have multiple discharge pipes with three or more independent flow paths.

[0107] The present invention may further include a nozzle housing 400 capable of mixing and spraying multiple fluids discharged through a pump housing 300.

[0108] A nozzle is a device that adjusts the direction of a flowing fluid and increases its velocity, with the cross-sectional area, pressure, and enthalpy at the outlet being smaller than those at the inlet.

[0109] The nozzle housing 400 of the present invention is also composed of a plurality of nozzle sections having the same characteristics, and each of the plurality of nozzle sections has a spray tube.

[0110] The injection pipe can be divided into one or more inner nozzles, each having an injection pipe that injects its own fluid into a specific nozzle section, and one outer nozzle, each corresponding to the specific nozzle section.

[0111] In this specification, a nozzle housing 400 that can be connected to two forms of discharge pipes 331 and 332 described as embodiments of the pump housing 300 is described as an example, but applications that connect to the pump housing 300 having variously formed discharge pipes can be described in the same manner.

[0112] Figure 6 shows an example of the features of a nozzle housing 400 according to the present invention, which can be connected to a pump housing 300 having two discharge pipes 331 and 332.

[0113] A second intake pipe 421 and two forms of second injection pipes 422, a second nozzle section 420 corresponding to the inner nozzle shown in A; and

[0114] The first nozzle section 410 includes the first intake pipe 411 and the first injection pipe 412, the injection pipe 422 of the inner nozzle, and the outer nozzle section 410 surrounding A;

[0115] An additional vortex plate 430 and brush head 440 are shown.

[0116] The intake pipes 411 and 421 are connected to the discharge pipes 331 and 332, and are inlets for nozzle sections 410 and 420 into which multiple fluids F1 and F2 discharged from the discharge pipes 331 and 332 flow.

[0117] The injection tubes 412 and 422 of the present invention can have various forms depending on the application.

[0118] The second fluid F2 injected from the second injection pipe 422 of the second nozzle section 420, which is the inner nozzle, can have a mixing channel R3 in which it mixes with the first fluid F1 injected from inside the first nozzle section 410, which is the outer nozzle, and flows in and moves through the first intake pipe 411 of the first nozzle section 410, forming a mixed fluid F3.

[0119] For a more detailed explanation, the nozzle housing 400 shown in Figure 1 as one embodiment of the present invention will be described in two embodiments.

[0120] The first embodiment of the nozzle housing 400 is illustrated by Figure 8 in the case where the first fluid F1 is water, the second fluid F2 is air, and the mixed fluid F3 is intended for use as fine-bubble water.

[0121] Figure 8 shows that water F1 flows into the first nozzle section 410, which has a first flow path R1 connected to the first discharge pipe 331.

[0122] Air F2 flows into the second nozzle section 420, which has a second flow path R2 connected to the second discharge pipe 332.

[0123] A nozzle housing 400 is shown in which fine bubbles of the mixed fluid F3 are generated in the mixing channel R3 and discharged.

[0124] At this time, the second injection tube 422 is a number of pores 423 that are spread out on the outer surface of the second nozzle section 420, as shown in Figure 7, and is actually formed of micropores whose size cannot be confirmed with the naked eye.

[0125] To push out air F2 through such fine pores requires extremely high pressure, which is one of the reasons why the present invention includes a reduction gear 120 and a rotating housing 200.

[0126] The air F2, which is injected through the pores 423 to form a fine airflow, mixes with the water F1 flowing through the first nozzle section 410 to form fine bubble water F3, and a mixing channel R3 is formed from the position where the fine bubble water F3 is formed.

[0127] At this time, a vortex plate 430 can be additionally provided in the mixing channel R3 in order to form a vortex in the microbubble water F3.

[0128] The two vortex plates 430 shown in Figure 6 thoroughly mix the mixed fluid F3 with each other to create fine-bubble water F3, and the fine-bubble water F3 thus formed is injected to the outside through the first injection pipe 412.

[0129] Furthermore, the fine bubbles of the mixed fluid F3 can be discharged to the outside through the brush head 440 connected to the first injection pipe 412.

[0130] The brush head 440 can adjust the spray direction of the microbubble water F3 and demonstrate its true value when applied to equipment that can utilize the cleaning power of the microbubble water F3.

[0131] As shown in Figure 6, such a brush head 440 has a head channel 441 formed on its inside through which fine bubble water F3 flows, and numerous injection holes 441a are formed at the end of the brush head 440.

[0132] Furthermore, a brush 442 consisting of multiple brushes is formed in the center of the area where the numerous spray holes 441a are located, allowing the user to perform tasks such as cleaning using the brush 442 together with the fine bubble water F3 sprayed from the brush head 440.

[0133] In the second embodiment of the nozzle housing 400, the first fluid F1 is water, and the second fluid F2 is also water. The purpose of use is to form cavitation and discharge it to the outside of the nozzle housing 400 to utilize the cavitation.

[0134] Cavitation occurs when water pressure drops below -1 atmosphere, and its duration is extremely short, but it can be prolonged somewhat by surrounding the water with high-pressure water.

[0135] Figure 9 illustrates how to create this type of cavitation F3.

[0136] Figure 9 shows that water F1 flows into the first nozzle section 410, which has a first flow path R1 connected to the first discharge pipe 331.

[0137] Water F2 also flows into the second nozzle section 420, which has a second flow path R2 connected to the second discharge pipe 332.

[0138] A nozzle housing 400 is shown, through which cavitation of the mixed fluid F3 is generated and discharged.

[0139] At this time, as shown in Figure 9, the second injection pipe 422 is formed by one or more venturi discharge passages 424, which are venturi tube-shaped and have a region on the inside where the cross-sectional area becomes even narrower.

[0140] At this time, if the water F2 passing through the venturi discharge passage 424 moves very quickly, cavitation will form when the pressure falls below a certain pressure.

[0141] Another reason the present invention includes a reduction unit 120 and a rotating housing 200 is to increase the speed of the water F2.

[0142] In this way, the cavitation F2 injected through the venturi discharge passage 424 is surrounded by the relatively low-velocity water F1 flowing through the first nozzle section 410, and is discharged as cavitation F3, which is the mixed water, from the position where the mixing passage R3 begins.

[0143] The aforementioned cavitation F3 has the effect of extending the lifespan of cavitation F2 by blocking its direct exposure to the atmosphere.

[0144] As described above, the nozzle housing 400 according to the present invention, having the configuration and embodiments described above, can also be modified in various ways when a diaphragm pump 1 has three or more pressurizing chambers or three or more independent flow paths, and can be applied to other uses.

[0145] The best embodiments are disclosed in the drawings and specification. Certain terms are used here solely for the purpose of illustrating the invention and not to limit its meaning or the scope of the invention as described in the claims. Therefore, a person with ordinary skill in the art will understand that a variety of modifications and equivalent other embodiments are possible. Accordingly, the true scope of technical protection of the invention should be determined by the technical idea of ​​the appended claims. [Explanation of Symbols]
