Description

[0001] The present invention relates to an air cylinder pump,

More particularly, the present invention relates to an oil syringe pump, and more particularly, to an oil syringe pump that pumps a pump for sucking and discharging wastewater by using an air cylinder, an oil syringe, To an air cylinder pump.

Generally, a cylinder refers to a machine that operates when a high-pressure air is sucked into or exhausted from a cylinder tube and the piston rod is projected in a linear direction in a cylinder tube to operate the object. Means a moving machine.

When the air is sucked into one side of the cylinder while the first piston rod is advanced, the piston is retracted and the piston rod fixed together is retracted to suck the liquid or gas into the pump tube. On the other hand, When the air is sucked, the piston is advanced to discharge the liquid or gas in the pump tube to the outside.

[0002] As disclosed in Japanese Utility Model Registration No. 0369038 (hereinafter referred to as "cylinder pump"), a cylindrical case having fluid inflow holes at both ends thereof and having a hole at the center of one end thereof, A cylinder which is located in the cylindrical case and has two cylinder heads which are not in close contact with the inner wall of the cylindrical case and which includes a head connection pipe having a fluid outflow hole between the cylinder heads; A drive shaft and an outflow tube connected to one end of the cylinder and connected to one end of the cylinder to linearly reciprocate the cylinder by the driving force of the driving means and connected to the fluid outflow hole of the head connection pipe to discharge the fluid to the outside, The outer circumferential surface of the head connecting pipe is positioned so as to close the inner circumferential surface of the cylindrical case, A rubber ring which is moved to the left and right sides of the fluid outlet hole so as to allow fluid to flow into one side of the cylinder and to allow the fluid introduced into the other side side to flow out through the fluid outlet hole; And an opening / closing substrate for selectively opening and closing the fluid inflow hole by a pressure generated by driving the cylinder.

The conventional cylinder pump having such a structure has a simple structure and has an effect of increasing the pumping efficiency by causing the inflow of the fluid into the pump and the outflow of the fluid out of the pump simultaneously in accordance with the driving of the cylinder.

However, the conventional cylinder pump has a problem in that the fluid can not be moved in the opposite direction because the fluid flows in and out in one direction.

That is, when the fluid flowing in and out of one direction is polluted sewage, the contamination remains inside the cylinder pump when the pumping operation is completed. To clean the sewage, the hose for sucking in the sewage is taken out and dipped in the washing water to flow in and out There is a troublesome problem in operation.

However, in the conventional cylinder pump, the opening / closing substrate, which is configured to flow fluid only in one direction, is automatically opened and closed by the advancing direction inside the cylindrical case There is a problem in that a pressure loss is caused even if a minute gap is generated, thereby increasing the operating cost and increasing the working time.

When the first air port 121 and the air supply hole 231 are aligned with each other by rotating the handle 232 of the first air switching valve 200, Moves the pump piston (160) by the cylinder piston (140) and the piston rod (150). At this time, the first on-off valve 420 is opened to communicate with the first water hose 421, and the second on-off valve 430 is closed to exhaust the air in the pump tube 310 to the outside.

next. The handle 232 of the air switching valve 200 is rotated while the first opening and closing valve 420 is closed and the second opening and closing valve 430 is opened to communicate with the second water hose 431, When the air port 131 and the air supply hole 231 are communicated with each other, the pump piston 160 retracts and wastewater flows into the pump tube 310.

The first on-off valve 420 is opened to communicate with the first water hose 421 in the initial state so that the wastewater in the pump tube 310 flows out to the ground, and the second on-off valve 430 is closed When the first air port 121 and the air supply hole 231 coincide with each other by rotating the handle 232 of the air switching valve 200 at the first position, the air moves forward together with the cylinder piston 140 and the pump piston 160, You can do it.

This can be repeated to get the amount needed for water quality testing.

In addition, after the necessary wastes are obtained, the above-mentioned operations are performed in reverse order to move the purified water in the direction in which the wastes are placed.

The second water changing means 500 of the second embodiment comprises a second tee pipe 510 formed in a " T " shape and having a third through hole 511 penetrated in three directions inside thereof, And is connected to one side of the T-shaped pipe 510, that is, one side of the third through hole 511 and the oil import /

The first water hose 512 is connected to the other side of the third through-hole 511 by a one-touch nipple 900 and is connected to the other side through a drain The second water hose 513 configured to flow is connected to the one-touch nipple 900.

In addition, the second T-shaped pipe 510 is provided with a third opening / closing valve 520 for controlling the movement of wastewater and purified water, and is installed inside the third opening / closing valve 520 The third valve ball 521 is rotatably installed to interlock with the handle 522. The third valve ball 521 passes through three directions.

The third valve ball 521 has an internal through-hole shape such that the first valve hole 521 is in a state of communicating with the first water hose import port 331 and the first water hose 512, And the second water hose 513 is communicated with the oil inlet / outlet port 331, the handle 522 is rotated upward by 90 degrees so that the through-hole shape of the third valve ball 521 becomes " The wastewater flows into the pump tube 310 through the opening and closing operation of the air switching valve 200 as in the first embodiment described above and then flows out to the ground, will be.

On the other hand, a bucket is provided at an end of the second water hose 431 (513). The water bottle 10 is a water quality inspection container for receiving wastewater discharged from the ground, or a cleaning container for containing water for cleaning. The water bottle 10 can be selected and replaced by the operator.

In addition, the first water hoses 421 and 512 suck the first water hoses 421 and 512, which are 100 meters or longer in length, in the wastewater to inspect the wastewater in the chamber 20, Is very difficult.

In order to solve this problem, the lower ends of the first water hoses 421 and 512 are disposed in the respective chambers 20 for inspection, and the upper ends of the first water hoses 421 and 512 are disposed inside the control box 30 .
