Description

Injector for mixing liquids

The present invention relates to a liquid mixing injector for mixing various liquids and injecting them into a container, and a liquid injection method using the same, and more particularly, to mixing industrial or edible liquids such as liquid medicine, food or cosmetics according to a required composition. And it relates to a liquid mixing injector and a liquid injection method using the same that can be easily injected into the desired amount inside the container.

In general, where a large automated means is not provided, in a process of injecting a small amount of liquid into a separate container from a storage tank or a large infusion tank, the operation is often performed manually using a funnel. In this case, in the process of injecting the liquid into the container, the injected liquid is leaked to the outside, causing economic losses, and the workplace is contaminated by the spilled liquid, resulting in unsanitary defects. In addition, since the process of injecting the liquid into the container is made by hand, the work efficiency is reduced, such as a lot of manpower and work time is required, there is a disadvantage that it is difficult to inject a certain amount of the correct amount into the container.

In order to solve this problem, Korean Registered Utility Model No. 20-037361 (designation name: liquid metering injector) can continuously inject a predetermined amount of liquid into a container by using a motor and a rotating cam equipped with a reducer. A liquid dosing device is shown.

Fig. 1 shows a perspective view of the liquid metering injector disclosed in the registration utility model, and Fig. 2 is a partial sectional view of a piston drive unit by a cam of the liquid metering injector shown in Fig. 1.

1 and 2, in the liquid dosing unit 25, a motor 4 equipped with a speed reducer 3 having output shafts 2 formed at both ends is installed in a box-shaped housing 1. On the adjustment screw rod 5 of the rotary cam 6 to which the adjustment screw rod 5 is attached to each end of the output shaft 2, the cam shaft 7 is connected to the upper and lower sides.

In addition, one side of the camshaft (7) is connected to the piston (8) by inserting a link (10) at the top with a first pin (9) to control the flow of the piston (8), the piston (8) Is coupled to the interior of the graduated cylinder (11). One end of the outlet 11 of the cylinder 11 is provided with a connector 14 connected to the internal outlet 13, and the inlet valve 15 and the outlet valve 16 are provided at both ends of the outlet 12. Connect.

The upper portion of the connector 14 is connected to the second pin 19 to allow flow to one side of the support 18 which is movably connected to the liquid amount adjusting hole 17 formed on the side of the housing 1 in the vertical direction. do.

A scale portion is formed on the front surface of the rotary cam 6 to check the amount of liquid, and the support screw 18 of the liquid amount adjusting hole 17 of the housing 1 and the adjustment screw rod of the rotary cam 6 ( By moving the camshaft 7 connected to 5), the moving distance of the piston 8 in the cylinder 11 is adjusted to control the amount of liquid injected into the vessel 22.

However, in the liquid meter injector 25 having the above-described configuration, although the motor is automatable and relatively accurate amount of liquid can be injected into the container, by using the motor 4 and the rotary cam 6, it is in use. Noise is generated and a problem arises in that the correct amount of liquid cannot be injected by the vibration. In addition, since it is not easy to disassemble and assemble, it is difficult to replace, repair or disassemble and clean the parts, and mechanically driven parts such as the reducer 3, the motor 4, the rotary cam 6 and the link 10 are exposed to the outside. Therefore, there is a problem that it is not easy to clean without decomposing using purified water or washing water.

On the other hand, Korean Utility Model Model No. 20-086157 (designation name: liquid injector) discloses a liquid injector capable of continuously injecting a liquid in a predetermined amount using air.

3 shows a cross-sectional view of the liquid injector presented in the utility model.

In the liquid injector 30, the piston 32 moves upward by the supply of air, and the liquid is supplied through the liquid supply port 35 by a sensor that detects the movement of the piston 32. Pressure of the air introduced through the air supply port 34 acts on the bottom space portion 38 of the piston 32 to push the piston 32 upward, and the piston 32 has an upper spring ( 37) to contract. At this time, the liquid is introduced through the liquid supply port 35, and the introduced liquid is injected into the container by a predetermined amount through the liquid inlet 36 opened through the liquid inlet passage 39.

However, even in the liquid injector 30 having the above-described configuration, a separate device is required for injecting the liquid by a certain precise amount, and there is a possibility that the liquid may leak out due to abrasion of the opening and closing hole 33 during long-term use. This happens. In addition, since the spring 37 is used, disassembly and assembly are not easy, and parts replacement, repair, or disassembly and cleaning are difficult.

Accordingly, one object of the present invention is to provide a liquid mixing injector capable of injecting liquid into a container in an accurate amount without noise and vibration through an air piston and a sensor, and a method of injecting liquid using the same.

Another object of the present invention is to provide a liquid mixing injector and a method of injecting a liquid using the same, by which a liquid mixing injector can be simply operated to allow anyone to easily mix the liquid and inject a desired amount into the container.

Still another object of the present invention is to have a simple configuration, not only can be cleaned without disassembling the liquid injector liquid mixing injector can be easily disassembled and assembled without using a specific tool when replacing parts or disassembly cleaning and this It is to provide a method of injecting the used liquid.

Still another object of the present invention is to configure a liquid mixer with an injector and a system so that mixing and injecting of liquids can be performed simultaneously, and the liquid can be used separately by separating the mixer and the injector to a necessary place. It is to provide a mixed injector and an injection method using the same.

Therefore, when the air in the second cylinder 192 is discharged to the outside and the pressure in the second cylinder 192 is lowered, the second piston 202 mounted on the second cylinder 192 is lowered. The first piston 201 connected to the second piston 202 by the connecting member 205 is also lowered in the first cylinder 191. The pressure in the first cylinder 191 is lowered by the lowering of the first piston 201, and the valve is connected to the valve hole 270 formed in the upper cap 235 installed at the upper portion of the first piston 201. The influence of pressure is transmitted to 115.

Due to the influence of the pressure, the suction port 255 formed in the valve 270 is opened and the injection port 260 is closed so that the liquid to be injected into the container 183 is inside the first cylinder 191 through the valve 270. Flows into. At this time, the numerical value of the ruler 160 installed in the frame 105 is checked, and a predetermined liquid is moved to the first cylinder 191 by moving the position of the indicating needle 250 using the first fastening bolt 301. To be sucked into the body.

Subsequently, when air is sucked into the second cylinder 192 and the pressure in the second cylinder 192 is increased, the second piston 202 mounted to the second cylinder 192 is raised, and the connection The first piston 201, which is connected to the second piston 202 by the member 205, is also raised in the first cylinder 191. The pressure in the first cylinder 191 is increased by the rise of the first piston 201, and the influence of the pressure is transmitted to the liquid introduced into the first piston 201.

Due to the influence of the pressure, the inlet port 255 formed in the valve 270 is closed and the inlet port 260 is opened so that a liquid hose to be injected into the container 183 is connected to the valve 270 and the valve 270. It is introduced into the nozzle 295 through.

That is, when the indicator needle 250 moves in the injector assembly 110 for injecting a predetermined liquid, one side of the first connection rod connected to the indicator needle 250 by the first fastening bolt 301 ( 241 is moved, and then the position of the first sensor 211 connected to the other side of the first connecting rod 241 and mounted in the second cylinder 192 is moved. The first sensor 211 detects the position of the second piston 202 and controls the amount of air introduced and discharged into the second cylinder 192 to thereby control the second piston 202 and the second piston 202. The stroke of the first piston 201 connected through the connecting member 205 is changed, and as a result, a predetermined liquid can be introduced into and discharged from the inside of the first cylinder 191.

In addition, the first sensor 211 detects one reciprocating motion of the second piston 202 to generate a signal, and the signal is transmitted to the controller 125 to determine the number of times liquid is injected into the container 183. Through the counter 335 installed in the controller 125 to display a number.

The liquid introduced into the nozzle 295 is injected into the container 183 supported by the pedestal 170 installed in the frame 105 to complete the injection of the liquid. At this time, the height of the nozzle 295 may be adjusted according to the size of the container 183 using the second fastening bolt 302 connected to the nozzle 295.

In addition, the nozzle assembly 120 may be operated asynchronously or synchronously by manipulating the second changeover switch 322 installed in the controller 125.

In the case of the general liquid, the nozzle assembly 120 is operated asynchronously. In this case, the nozzle 295 injects the liquid into the container 183 while being fixed at the initially designated position.

In the case of a liquid that splashes a lot of liquid to the outside of the container 183 or bubbles are a problem in the injection, the nozzle assembly 120 is operated in the synchronous manner. In this case, the nozzle 295 is lowered close to the bottom surface of the container 183 before the injection of the liquid starts, and then gradually rises as the injection of the liquid starts to the position before the nozzle 295 is lowered. Ascending completes the injection of the liquid.

When the nozzle assembly 120 is operated synchronously, air is introduced into and discharged from the third cylinder 193, and a control rod housing 310 in which a pressure difference according to the inflow and discharge of the air is connected to the third cylinder 193. It is transmitted to the control rod 305 through. Therefore, the nozzle 295 connected to the control rod 305 using the second connection rod 242 is raised or lowered according to the movement of the control rod 305.

Further, a second sensor 212 is installed at one upper portion of the inside of the reservoir 485 to detect the amount of liquid in the reservoir 485. At this time, the reservoir 485 is manufactured by sheet metal using a metal that is not rust, such as stainless steel or aluminum, it can be manufactured by varying the capacity according to the installation space or the user's requirements.

The second motor 352 is installed on the upper surface of the plate 500, the motor shaft of the second motor 352 is connected to the shaft of the pump 490 to drive the pump 490. In addition, the outlet 520 of the pump 490 is connected to the first connection hole 521 of the reservoir 485, the absorption port 515 is connected to the third coupling portion 533 of the water level regulator 510.

Since the operations of the remaining parts except for the intermediate storage assembly 440 are the same as those of the first embodiment, the description thereof will be omitted.

10 and 11, the liquid introduced into one side of the first connecting pipe 371 from the mixing tank 340 is connected to the first coupling part 531 formed in the water level regulator 510. It is introduced into the water level regulator 510 through the other side.

The liquid flows into the absorption port 515 of the pump 490 connected to the third coupling part 533 formed in the water level regulator 510. At this time, the second motor 352 mounted to the plate 500 is operated by using the ON switch 471 installed in the controller 430 to drive the pump 490 connected to the second motor 352. That is, the liquid introduced into the absorption port 515 of the pump 490 by the driving of the pump 490 moves to the storage tank 485 through the water outlet 520.
