Abstract

A high-viscosity liquid transfer apparatus is disclosed. In one embodiment of the present invention, a flexible connector, in which two connectors having 4 degrees of freedom are coupled, is applied to a method for connecting an air motor and a lower pump, such that the lower pump carries out a pumping operation along the lower pump axial line regardless of the operation of the air motor, even if an offset, in which the axial lines thereof are misaligned from each other or the centers of the axial lines are spaced, has occurred in a random circumferential direction. When an intake seal is closed, a valve seat, which is fixed to the lower pump, freely moves left and right so as to naturally match the axial line of a lower pump piston, and a 2-degree-of-freedom gyro ring holder is used to solve the misalignment of the axial lines of the lower pump and a container containing liquid, such that the container is not influenced thereby even though the container is spaced at a predetermined gap from the axial line of the lower pump, and an operating load is reduced since the lower surface of an inductor plate allowing the liquid to flow is machined into a spiral, inclined surface so as to allow the liquid to easily flow along the inclined surface. Therefore, the wear of and damage to a packing, caused by the misalignment of the axial lines or the bending of the axial lines, are minimized such that durability is increased with respect to a leakage.

Description

High Viscosity Liquid Transfer Device

The present invention relates to a high-viscosity liquid transfer device, and more particularly, to prevent or prevent the wear and concentration load of the sealing ring or packing inside the pump due to the eccentricity or twisting of the pump shaft when pumping the high-viscosity liquid to prevent leakage It relates to a high viscosity liquid transfer device to increase the durability.

Priming piston reciprocating displacement pumps are generally well known and US Pat. No. 5,147,188 discloses a technique for piston pumps.

The highly viscous liquid has a very high viscosity of the material itself, so that it is difficult to transfer the liquid to the final discharge gun at one time. Therefore, the high viscosity liquid generally adopts a configuration method of discharging the secondary pump from the secondary pump to the gun.

At this time, a method commonly used as a primary pump is amplified to a high pressure from the lower pump 200 with an air motor 100 using compressed air, and then transfers the liquid to a gun or a secondary pump. . In addition, since the viscosity of the liquid is very high, the air motor 100 and the lower pump 200 may be smoothly sucked into the lower pump 200 when the liquid is amplified from the lower pump 200 by the air motor 100. ) And the air pressure is applied to the ram pump 300 on one side to add a constant pressure to the high viscosity liquid.

That is, as shown in Figure 2, the compressed air acts on the ram piston 320 of the ram pump 300, the air motor 100 and the lower pump 200 is moved downward by the ram piston 320 integrally and the lower pump Since the inductor plate 250 having a large area mounted below the 200 is in a state of pressurizing the liquid, the suction of the lower pump 200 makes the liquid easy to suck down.

On the contrary, when the liquid inside the container 400 is used to replace the empty container with a full container, as shown in FIG. 3, when the direction of the compressed air is supplied to the lower portion of the ram piston 320, the ram piston 320 is As it rises and simultaneously supplies air to the lower part of the inductor plate 250, the air motor 100 and the lower pump 200 are raised together with the inductor plate 250 to escape the empty container 400. Will go out.

By replacing the empty container with a full container and supplying compressed air as shown in FIG. 2 to gradually lower the ram piston 320, the air motor 100, the lower pump 200 and the inductor plate 250 are lowered integrally. While starting the contact with the high viscosity liquid upper surface in the container 400, and then applying a certain pressure to the high viscosity liquid while being sealed enters the ready state of operation.

As described in detail in the pumping process of the actual liquid in a state in which the high viscous liquid is constantly pressed, as shown in Figure 4, the conventional pump is an air motor 100, the lower pump 200 and the inductor plate 250, It consists of a ram pump 300 comprising a holder plate 600 and tie rod 620, and ram piston 320 to tie them together.

The lower pump 200 pumping the actual liquid has a ball valve 230, an intake seal valve 240, and a check plate valve 290, and the chamber 1 201 and chamber 2 202 which collect the liquid therein. ), A structure having three rooms of chamber 3 (203).

In FIG. 5, when the air motor piston 120 operates downward by compressed air, the intake seal valve 240 of the lower pump 200 is closed while the piston rod 210 of the lower pump 200 also operates downward. Chamber 1 201 is evacuated and the liquid filling chamber 2 202 is compressed.

Accordingly, the liquid in chamber 2 202 is opened by moving the ball valve 230 upward by the vacuum pressure in chamber 1 201 and the pressure in chamber 2 202, and the liquid is opened in chamber 2 202 by chamber 1 201. Will be moved to).

At this time, the volume of the chamber 1 201 is smaller than the volume of the chamber 2 202, so that the liquid moved from the chamber 2 202 to the chamber 1 201 fills the chamber 1 201 and the surplus liquid remaining in the discharge port 220-. 2) will be discharged.

Meanwhile, when the piston rod 210 of the lower pump 200 moves downward by the air motor piston rod 120, the chamber 3 203 also becomes a vacuum pressure, and the check plate valve 290 opens to receive a constant pressure. The liquid in the container 400 is introduced into the chamber 3 203.

In FIG. 6, when the compressed air is supplied in the opposite direction and the piston rod 120 of the air motor 100 operates upward, the piston rod 210 of the lower pump 200 also operates upward. When the ball valve 230 is closed, the intake seal valve 240 is opened and the check plate valve 290 is closed.

Therefore, the liquid in chamber 1 201 is compressed and discharged to the discharge port, and the liquid in chamber 3 203 moves to chamber 2 202 by pressure to fill chamber 2 202. As such, the pump for transferring the high-viscosity liquid discharges the liquid to the discharge port when the lower pump 200 moves downward and moves upward by the air motor 100.

As shown in FIG. 8, the inductor plate 250 has a fastening part 251 having an upper and lower openings formed thereon to be coupled to the intake housing 242, and a disc part 252 is formed at an outer circumference thereof, and a passage therein. 254 is formed and pressurized high viscosity liquid may be conveyed upwardly through the passage 254.

In the conventional high viscosity liquid pump operating as described above, as shown in FIG. 7, the air motor 100 and the lower pump 200 are fastened and screwed together at two locations, and the holder plate 600 and the tie rod ( 620 is fastened and coupled by screws, and the piston part operating in the lower pump 200 is coupled by screwing at two places.

A plurality of packings 170 are coupled to the operating part and the fixing part of the lower pump 200, respectively, and are bound by the packing nut 172 to maintain the airtightness of the liquid. Due to the assembly error, the axis of the air motor 100 and the axis of the lower pump 200 is inconsistent.

As shown in Figure 7, the conventional high-viscosity liquid pump is coupled to all the main parts from the air motor 100 by a screw fastening method.

That is, the connection of the air motor piston rod 120 and the lower pump piston rod 210, the connection of the lower pump piston rod 210 and the ball valve housing 260, the ball valve housing 260 and the valve piston 262, The valve piston 263 and the lower piston rod 263 and the air motor 100 and the tie rod 620, the tie rod 620 and the holder plate 600, the holder plate 600 and the lower pump 200 are mutually As the assembly of bolts or nuts is assembled, the axis of the air motor 100 and the axis of the lower pump 200 become inconsistent due to the mixing tolerance of each part and the assembly tolerance, and the container 400 and the lower pump which contain liquid. There is always an axis mismatch between 200.

In addition, the stopper 270 of the intake seal valve 240 fixed inside the lower pump 200 may not coincide with the operating axis of the lower pump piston rod 210 moving to a processing and assembly tolerance.

Accordingly, the packing which requires the liquid tightness due to the axis mismatch with the piston rod 210 movement of the lower pump and the piston rod 210 movement of the upper air motor 100 and the axis mismatch when the intake seal valve 240 is closed. Ryu is subjected to a concentrated load in one reverberation and has a defect that causes uneven wear and rapid damage resulting in leakage of liquid.

The present invention provides a free air flow to the valve seat having a closed structure in contact with the intake chamber and the flexible connector for disconnecting the operating axis of the air motor and the axis of the piston of the lower pump not interfere with or influence each other. Regardless of the direction of movement of the motor, the lower pump operates on its own axis to remove concentrated loads on the packings. In addition, the lower pump not only facilitates the inflow of liquid but also naturally flows the liquid. The present invention relates to providing a highly viscous liquid conveying device having a spiral structure of a lower surface of an inductor plate so as to lower a load of.

High viscous liquid transfer device according to an embodiment of the present invention, by applying a flexible connector that combines two connectors having four degrees of freedom in the connection method of the air motor and the lower pump axially shifted from each other in the circumferential direction or axial The lower pump should operate according to its own axis regardless of the operation of the air motor even if the offset of the center of the valve is separated, and allow the valve seat fixed to the lower pump to flow freely from side to side when the intake seal is closed. By naturally matching to the axis of the lower pump piston, the two degree of freedom gyro holder is applied to solve the axis mismatch between the container containing the liquid and the lower pump, so that even if the container is spaced apart from the axis of the lower pump. The lower surface of the inductor plate into which the liquid By the processing liquid to the surface to be easily introduced along the slope it was to reduce the work load.

According to the present invention, there is an effect that can increase the durability against leakage by minimizing the wear and damage of the packing due to the mismatch of the axis or the bending of the axis.

In addition, work loss can be reduced by minimizing maintenance management due to leakage, and energy saving can be achieved by streamlined pumping efficiency.

As shown in FIG. 10, the lower pump 200 is formed to horizontally flow the valve seat 206-1 in contact with the cone valve 232.

Therefore, when the cone valve 232 is closed, the cone valve 232 is naturally matched with the operating axis, and the conventional three chambers (chambers) have two chambers (first and second chambers b1 and b2). The energy efficiency is improved by minimizing the flow resistance of the furnace liquid.

That is, a first chamber b1 is formed between the upper portion of the finger stopper 233 and the annulus 221 of the shaft 220 in the first body 205, and the first body 206 is formed in the second body 206. Two chambers b2 are formed.

The present invention is to ensure that the axis between the air motor 100, the lower pump 200, and the container 400 containing the high viscous liquid is operated independently of each other and flexible connection of each part to avoid mutual influence I want to have freedom.

A flexible connector 700 having a multiple degree of freedom is provided to remove the influence due to the axis mismatch between the upper air motor 100 and the lower pump 200.

The flexible connector 700 is connected to the piston shaft 120, the link upper 710, the first coupling piece 711 is formed at the bottom; A link body 720 whose upper portion is hinged to the first coupling piece 711 of the link upper 710 by a pin 712; A second coupling piece 732 which is hinged to the lower portion of the link body 720 is hinged by a pin 733 is formed on the upper portion, the lower link linker is connected to the operating shaft 210 of the lower pump 200 ( 730); is configured to include.

Each of the first and

second coupling pieces

711 and 732 is composed of

vertical members

7111 and 7321 formed at both sides, and horizontal members 7112 and 7222 connecting both vertical members 7111 and 7121 to both sides. The through holes are formed in the 7111 and 7121 to couple the

pins

pins

712 and 733, respectively, to connect two four degree of freedom links. You get an effect.

Therefore, the axis between the air motor 100 and the lower pump 200 can be easily connected even if they are offset or bent from each other, as shown in FIG. 13, and the piston axis of the air motor 100 and the lower pump 200 are Even if the piston axes do not coincide, they can be operated along their own operating axis without affecting each other.

Meanwhile, two degrees of freedom gyro ring holders 800 are provided to remove the influence of the axis mismatch between the lower high viscosity liquid container 400 and the lower pump 200.

As shown in FIG. 17, the highly viscous liquid container 400 has two rings on the outside and the inside so that it can operate along its own axis without being affected even if it is spaced apart from the operating axis of the lower pump piston. A gyro ring 820 having two degrees of freedom is included.

As shown in FIG. 17 and FIG. 18, the two-degree of freedom gyro holder 800 is a gyro ring coupled to the outer upper portion of the first body 205 of the lower pump 200 by a hinge pin 841 ( 820 and the outer body 840 is coupled to the outside of the gyro ring 820, the outer body 840 is coupled to rotate the symmetrical coupling pins 842 on both sides of the gyro ring 820, the outer body The lower end of the tie rod 620 is coupled to 840.

On the other hand, as shown in Figure 19 to 23, the inductor plate 250 is in contact with the high viscosity liquid to induce the liquid flow into the lower pump at a constant pressure, the contact surface is formed by the spiral inclined surface 258 of the liquid Flow flows naturally into the center and can be easily introduced into the lower pump 200.

The inductor plate 250 is provided with a fastening part 252 to which the lower end of the second body 206 of the lower pump 200 is fitted, and the fastening part 252 is formed by penetrating up and down. A disc portion 254 is formed at a lower end of the portion 252, and a bottom surface of the disc portion 254 is recessed inward to form a recess 256.

The concave portion 256 is formed with an inclined surface 258 on one side.

Accordingly, when the inductor plate 250 is pressed, the high viscosity liquid introduced into the recess 256 along the inclined surface 258 may pass through the fastening portion 252 and flow into the lower pump 200.

Referring to the operation of the piston pump according to an embodiment of the present invention.

As shown in FIG. 14, when the air motor 100 operates downward, the operation shaft 210 and the shaft 220 and the piston rod 230 of the lower pump 200 operate downward and the cone valve 232. The finger stopper 233 is operated downward by the action force of the spring 234 and the cone valve 232 is closed by contacting the valve seat 206-1.

As a result, the liquid in the first chamber b1 is compressed and discharged to the discharge port 220-2.

At the same time, the downward operation of the piston rod 230, the valve piston (v1) at the end is moved downwards, the second chamber (b2) generates a vacuum pressure, the high viscosity liquid having a constant pressure of the lower check plate valve 290 is pushed into the second chamber b2.

During operation downward, the high viscosity liquid in the first chamber b1 is discharged, and the process of filling the high viscosity liquid into the second chamber b2 is simultaneously performed.

Meanwhile, as shown in FIG. 15, when the air motor 100 operates upward, the piston rod 210 of the lower pump 200 also operates upward, and the lower pump 200 ends the piston rod 210. Of the check plate valve 290 closes the valve piston (v1) by the action of the spring force, the liquid in the second chamber (b2) is compressed, the first chamber (b1) is a vacuum valve to generate a cone valve 232 is pushed, and the high viscosity liquid moves from the second chamber b2 to the first chamber b1.

Since the volume of the first chamber b1 is smaller than that of the second chamber b2, the surplus liquid remaining after filling the first chamber b1 is discharged to the discharge port 220-2.

Even in such an upward operation, the lower pump 200 performs a process of discharging the liquid to the discharge port 220-2.

Meanwhile, the compressed air acts on the ram piston 320 so that the air motor 100 and the lower pump 200 are moved downwardly by the ram piston 320 and the inductor plate 250 mounted below the lower pump 200. Since the state is to press the liquid to make it easy to suck the liquid down during the suction action of the lower pump (200).

On the contrary, when the liquid inside the container 400 is exhausted and the empty container is to be replaced with a full container, when the compressed air is supplied to the lower portion of the ram piston 320, the ram piston 320 rises and at the same time the inductor plate. As the air is supplied to the lower part 250, the air motor 100 and the lower pump 200 are raised together with the inductor plate 250 to exit the empty container.

Replace the empty container with a full container and supply compressed air again to gradually lower the ram piston 320 so that the air motor 100, the lower pump 200, and the inductor plate 250 are all lowered together, and the viscous liquid Starting contact with the top surface, followed by a constant pressure on the viscous liquid while sealed, results in ready-to-run conditions.

Meanwhile, as shown in FIG. 16, when the lower pump piston rod 210 operates downward to close the valve, the axis of the valve seat 206-1 and the operating axis of the lower pump piston rod 230 do not match. Even though the valve seat 206-1 secures a constant clearance space t1 and t2 from side to side, the valve seat 206-1 naturally coincides with the operating axis of the lower pump piston rod 210.

In FIG. 25, when the air motor 100, the lower pump 200, and the liquid container 400 are arranged with different axes, the inductor plate 250 is inclined at a predetermined angle θ, and the axis The angle of inclination of is 't'.

Accordingly, the axis of the flexible connector 700 and the two degrees of freedom gyro ring 820 may be maintained to be aligned in a vertical state.

Although the present invention has been described in connection with the above-mentioned preferred embodiments, it will be readily apparent to those skilled in the art that various modifications and variations can be made without departing from the spirit and scope of the invention, all such modifications and modifications being attached It is obvious that the claims belong to the claims.

The highly viscous liquid has a very high viscosity of the material itself, which makes it difficult to transfer the liquid to the final discharge gun at a time, so that it is possible to provide a piston pump that discharges from the secondary pump to the gun, usually through the primary pump. Minimize the wear and damage of the packing. There is an economical advantage that can reduce work loss by minimizing maintenance management due to leakage, and energy saving by efficient pumping with liquid flow.
