Background

In the field of surface water purification treatment technology, a water treatment system is mostly adopted for purification treatment, a water treatment device is a large water tank with a water inlet at one end and a water outlet at the other end, the large water tank is divided into a plurality of sections which are communicated in sequence according to the flowing direction of inlet water to outlet water, and the large water tank generally comprises the following sections or most sections, such as a flocculation zone, a reaction zone, a rectification zone, a water distribution zone, a precipitation zone, a water collection zone and a water outlet zone.

The drinking water safety problem concerns the health and life safety of people and the sustainable development of economy. The reasons for the unsafe drinking water are: the water quality does not reach the standard, the operation is convenient, the operation management is complex, the water supply guarantee rate is low, etc. The effluent quality can be effectively improved through conventional precipitation and filtration processes, and the addition of a flocculating agent liquid medicine and the accurate addition of a filtered disinfectant in a precipitation link are of great importance. Compared with the operation of a town water treatment facility system, the management of the agricultural sewage treatment site lacks professional operation and maintenance personnel, professional technical personnel lack, and power equipment facilities have more problems in operation, so that the risks of low equipment perfectness rate, increased potential safety hazards and the like are caused. And the capacity of part rural power grid facilities is limited and the access of overlarge load is difficult to bear, so the development of unpowered and low-power water treatment equipment has wide application requirements.

The Chinese utility model with the publication number of CN202754815U discloses an unpowered constant liquid material gravity feeding device for water treatment, which is characterized in that a feeding floating barrel is arranged in a medicine storage tank, the middle part of the side wall of the feeding floating barrel is provided with a weir port barrel in which a counterweight is arranged, and a discharge port is arranged at the lower part of the barrel. Through the effect of the weight with constant weight, the feeding floating barrel just sinks to the position where the medicament can enter from the weir crest and flows out from the discharge hole, so that unpowered constant feeding is realized.

The Chinese utility model patent with the publication number of CN209276178U discloses a device for unpowered constant-speed dropwise adding of a liquid river and lake treatment medicament, which comprises a shell and a top cover, wherein a charging tank is arranged on the inner side of the shell, and the top cover is used for sealing an opening at the top of the shell; a central hole is formed in the top cover, one end of the dropper penetrates through the floating disc and is inserted into the liquid medicine in the charging tank, so that the dropper is communicated with the liquid medicine, the port of the dropper is positioned below the liquid level, and the other end of the dropper and one end of the sleeve can be axially movably assembled; the floating disc floats on the surface of the liquid medicine in the charging tank; the other end of the sleeve pipe and one end of the siphon pipe can move upwards in the axial direction for assembly, the other end of the siphon pipe is communicated with one end of the liquid suction hopper through a connecting hose, and the other end of the liquid suction hopper is communicated with the dripper. The siphon-type liquid medicine injection device realizes the injection of liquid medicines through a siphon principle, is more advanced than the scheme disclosed by CN202754815U, has no power consumption and is low in cost.

However, the two devices have the defects that the drug solution can not be automatically started and stopped as required when the drug solution is put in, the former has the defect that the drug solution is easily polluted by the environment due to the opening of the drug storage tank, and the latter has the defect that the drug solution can be added only by opening the sealing cover of the feed port when the drug solution in the tank is used up because the whole device floats on the water surface of rivers and lakes though the charging tank is relatively closed. Therefore, the solution disclosed in CN209276178U is not suitable for dosing in a water treatment system, or when it is used in a water treatment system, it cannot properly start dosing or stop dosing according to the actual condition of the water flow rate, i.e. the water level, of the water treatment system, and also cannot properly and automatically replenish the chemical solution into the chemical tank.

Instructions for dosing device

The unpowered automatic medicine replenishing process of the medicine replenishing assembly 43 is as follows: referring to fig. 7, when the liquid medicine in the medicine tank 10 is over the top of the float 433, the float 433 drives the valve body 434 to move up against the conical table 435, so that the medicine tank 10 cannot be replenished with liquid medicine from a large-capacity medicine source such as a medicine barrel or a medicine pool connected by the flange 42.

Referring to fig. 6, as the liquid medicine in the medicine tank 10 is gradually dispensed from the siphon dispensing assembly 2, the liquid medicine level in the medicine tank 10 gradually drops, and when the liquid medicine level drops to a certain extent, the float 433 drops, so that the valve body 434 drops away from the conical table 435, and the liquid medicine in the pipeline 41 is continuously and sequentially replenished into the medicine tank 10 from the medicine inlet 436 and the medicine outlet 437.

When the source water volume of the water treatment system 5 is reduced, the water level in the section is relatively reduced, the floater 31 is also reduced, the straight rod 32 and the connecting rod 33 drive the valve core 34 to move leftwards from the state shown in figure 5, the air passing area of the air hole is gradually closed, the structural parameters of the air hole valve component 3 and the siphon adding component 2 are properly selected, the flow speed of the siphon adding component 2 can be reduced along with the reduction of the air passing area, and the adding of the liquid medicine can be matched with the treated water volume. When the source water amount of the water treatment system 5 is small to a certain degree, for example, when the source water does not flow into the water treatment system 5 any more, the float 31 drops to the state shown in fig. 5 along with the water level, at this time, the valve core 34 completely closes the air hole 15, the liquid level of the liquid medicine in the medicine tank 10 drops along with the continuous outward throwing of the siphon throwing assembly 2, so that the air pressure in the sealed medicine tank 10 is lower than the outside, and the siphon throwing is stopped automatically without power. When the source water flows into the water treatment system again, the water level rises, and the air hole valve component 3 gradually opens the air hole 15 along with the rise of the water level, so that the normal dosing is carried out.

The utility model discloses a charge device need not power such as any electric power in above-mentioned working process.
