Description

TECHNICAL FIELD [0001] The present invention relates to a Dipper Type Liquid Chemical Feeder With Inside Dipper and Shaft stream,

It is very important to continuously and quantitatively add liquid chemicals for water treatment such as flocculants, disinfectants, and pH adjusters used in water treatment or underwater and wastewater treatment processes in proportion to the amount of water being introduced into the treatment plant.

If the amount of liquid supplied is insufficient and the amount of liquid is not proportional to the amount of water to be treated, if the amount of the liquid is insufficient or excessive, the treatment efficiency is deteriorated and the whole water treatment process is deteriorated. As a result, the cost of chemicals and power increases, Generation, environmental destruction, and the like.

1, the liquid medicine introduced from the liquid medicine storage tank 1 passes through the purified water level valve 2, flows into the chemical tank 3, and then flows into the purified water level valve 2 ) Maintained a constant water level at all times.

The dripper wheel 6 attached to the rotary shaft 5 by the drive motor 4 simultaneously rotates under the condition that the level of the liquid medicine in the chemical tank 3 is always constant and the liquid medicine in the chemical tank 3 is pumped up, (7), the liquid medicine is supplied toward the injection point by gravity using a natural descent method.

FIG. 2 is a detailed view of a dippers wheel 6 installed inside the medicine tank 3 of FIG. 1. As shown in the drawing, each of the dippers 8 maintains a certain level in the medicine tank 3 And the liquid medicine is gradually flowed toward the central portion of the rotary shaft 5, the flow direction of the liquid medicine is gradually reduced from the discharge guide 9 to the discharge port 9 7) by gravity.

FIG. 3 is a graph showing the amount of liquid medicine input relative to the revolution number of a conventional dipper type liquid medicine dispenser. As shown in FIG. 3, the discharge start point 10 of eight dippers during one rotation of the dipper wheel 6, An end point (11) and a shutdown interval (12) have occurred.

8 drippers 8 are attached to each of the dipper wheels 6 and each of the dippers 8 is operated by filling, rising, and discharging. Therefore, after one diper 8 finishes discharging, The occurrence of the interruption section 12 in which the injection of the liquid medicine is stopped is generated until the dispenser 8 starts to discharge the dispenser 8, which is the maximum defect of the dispensing liquid medicine dispenser.

The problem of the conventional dipper type liquid medicine dispenser is that the liquid medicine discharge is not continuous due to the error generating part 13 and the pulse flow is generated intermittently.

The amount of the liquid medicine to be supplied to the control panel 19 in proportion to the amount of water to be treated by the water treatment or the wastewater treatment plant is required to be almost linear as in the case of the average reference amount 14. However, in the conventional dipper type liquid medicine injector, Flow is generated intermittently, it is necessary to input a larger amount of the liquid medicine than the average reference amount (14) when setting the amount of the liquid medicine in the actual water treatment and the wastewater treatment plant. Therefore, It was a waste of medicine.

Of course, there are other ways of injecting liquid chemicals, such as metering pumps and flow meter control valves, in addition to the conventional dipper type. However, since the injected state of liquid chemicals can be easily grasped and maintenance is easy, liquid chemicals can be injected somewhat And the conventional dipper type liquid medicine dispenser is used.

In order to minimize the error generator 13 caused by the pulse flow, the number of revolutions of the dipper wheel 6 may be increased or eight or more dippers 8 may be installed and operated per dipper wheel 6 When the number of revolutions of the dipper wheel 6 is set to a high speed, the liquid medicine in the chemical tank 3 is rocked and the liquid medicine pumped up by the dipper 8 The method of minimizing the error generation section 13 by increasing the number of the dippers 8 installed on one dippers wheel 6 is performed by the dippers 8, Since the dipper 8 itself is formed to be bent at about 90 degrees so that the liquid medicine can flow smoothly in a certain amount in the direction of the center of the rotary shaft 5, it is difficult to install eight or more within a limited circumferential angle of 360 degrees , The amount of dipper (8) increases The amount of the discharge guide 9 has to be increased. As a result, the discharge passage becomes narrow and complicated. As a result, the discharge of the liquid medicine is not smoothly performed, and the precision is further reduced.

The technical problem to be solved by the present invention is to provide an apparatus and a method for injecting a liquid medicine into a water treatment process or a wastewater treatment process, in which a dropout period (12), which is a cause of pulsing flow, (10) and the discharge end point (11) of the dippers (8) are overlapped with each other so that the liquid medicine can be injected precisely and continuously, and a method thereof, And a method for enhancing the effluent treatment efficiency.

4, the liquid medicine introduced from the liquid medicine storage tank 1 passes through the purified water level valve 2, flows into the chemical tank 3, and then flows into the purification tank 3, The valve 2 always maintains a constant water level.

The rotation of the axial dripper wheel 15 is stopped by the drive motor 4 while the liquid medicine level in the chemical tank 3 is always constant, The liquid medicine is pumped up and the liquid medicine is introduced into the inlet of the fixed shaft 16 through the oil tool 18 drilled at the center of the body of the axial dipping wheel 15 and is then subjected to natural descent treatment through the discharge pipe 17 The method of supplying the liquid medicine toward the point is used.

Fig. 5 is a detailed view of the axial dripper wheel 15 provided in the chemical tank 3 of Fig. 4. As shown in Fig. 5, when the axial dripper wheel 15 fills up the liquid medicine and rises, Flows into the inlet port of the fixed shaft 16 along the discharge port 18, and is discharged through the discharge pipe 17.

This method is a method for eliminating a pulse flow generated in a conventional dipper type liquid medicine dispenser. In this method, the stopping section 12 of FIG. 3 is removed to minimize the error generating section 13 Thereby enabling the continuous introduction of liquid medicines.

The conventional shape of the dipper 8 is bent by almost 90 degrees in order to smoothly and continuously flow the liquid medicine discharge so that no more than 8 dippers 8 can be installed so that the stopping interval 12 of the third figure occurs, The axial flow dewatering wheel 15 according to the present invention restricts the diameter of the oil tool 18 drilled in each dipper regardless of the shape of the dipper so that the liquid medicine can not be discharged at a time and flows continuously Allowing you to install 16 dippers or more.

That is, since the discharge time is delayed by limiting the diameter of the liquid medicine so that the liquid medicine can flow slowly through the oil tool 18 of the axial dipping wheel 15 only for a predetermined time, the conventional dipper is bent by about 90 degrees, The discharge start point 10 and the discharge end point 11 are overlapped with each other because the next dipper starts discharging before one dipper finishes discharging. As a result, The generation portion 13 is remarkably reduced.

Further, in the conventional dipper wheel 6 of the dipper-type liquid medicine dispenser, since the discharge guide 9 is gathered at the central portion of the rotary shaft 5, the drainage area is reduced when a large number of dips 8 are installed, However, the axial dripper wheel 15 according to the present invention has a structure in which the periphery of the inlet of the fixed shaft 16 made of pipe is sealed by the contact rotary part of the axial dripper wheel 15, The liquid medicine once pumped is discharged to the input point without causing any leakage of water, so that it is possible to inject the liquid medicine more precisely.

FIG. 6 is an input curves of the axial-flow dipper-type liquid medicine dispenser according to the present invention. As shown here, the discharge start point 10 and the discharge end point 11 are overlapped with each other, Since the two dippers simultaneously discharge a small amount of the liquid medicine at the overlapped portions, the result is that the error generating portion 13 is compensated. Therefore, it is possible to accurately and continuously provide the liquid medicine proportional to the flow rate of the raw water flowing into the water treatment plant It is possible to inject liquid medicine.
