Description
Technical Field
The utility model relates to the field of sewage treatment devices, in particular to a constant-current dosing device for industrial sewage treatment.
Background
In phosphorite mining and ore dressing, a large amount of wastewater is generated. The phosphorus content and turbidity in the waste water are high, and the waste water cannot be directly discharged. Therefore, phosphorite can be discharged after reaching the standard of the environmental protection department after being treated by series of wastewater. In all current water treatment facilities, the efficient and low-cost mode is to put polyaluminium chloride (PAC) and Polyacrylamide (PAM) into water, and then to be supplemented with a sedimentation tank. The dosage of PAC and PAM is related to a plurality of factors such as water quality pollution condition, water flow and the like. Because closed-loop control of the dosage of the medicament needs to be added with a plurality of water quality and quantity monitoring devices, the system cost is increased, and therefore, the aim can be achieved by adopting open-loop control for sewage treatment.
The open loop controlled mode of administration is the most economical. According to the daily flow and the water quality condition, a dosing valve communicated with the medicine storage tank is opened, so that the medicine is dripped into the sewage. However, the traditional medicine feeding mode has a problem that uniform medicine feeding cannot be guaranteed, because the higher the water level of the medicine storage tank is, the higher the water pressure is, the higher the medicine dropping speed of the medicine feeding valve is, and the larger the medicine dropping amount in unit time is.

In order to achieve the purpose, the utility model adopts the technical scheme that: the utility model provides a constant current charge device for industrial sewage treatment, includes medicine storage tank, be equipped with the support that can reciprocate along with liquid level on the medicine storage tank lateral wall, be fixed with the hose on the support, the hose both ends are water inlet and delivery port respectively, and the water inlet is located medicine storage tank inside and is located the liquid level below, and the delivery port is located medicine storage tank outside, the water inlet is higher than the delivery port, and the difference in height between the two keeps invariable. And a flow limiting mechanism is also arranged on the water outlet of the hose.
Furthermore, a buoy is fixed on the bracket and drives the bracket to move up and down along with the change of the height of the liquid level.
Further, be equipped with the slide rail on the medicine storage tank lateral wall, the support passes through slide rail sliding connection on the medicine storage tank lateral wall.
Further, the flow restricting mechanism is a control valve.
Further, the height difference between the water inlet and the water outlet is not less than 1cm
Compared with the prior art, the utility model has the following beneficial effects:
according to the utility model, a buoy and a support are adopted, the inner section of the hose, namely the water inlet, and the outer end of the hose, namely the water outlet, are fixed on the support, and the height difference between the inner section and the outer section of the hose is constant, so that the water pressure between the water inlet and the water outlet can be kept constant, the water outlet can be kept at a constant dropping speed by adopting a siphon method, and the dropping dosage in unit time can be kept constant.

Drawings
Fig. 1 is a schematic view of the overall structure of the present invention.
In the figure: 1. a medicine storage tank; 2. a support; 3. a hose; 31. a water inlet; 32. a water outlet; 4. a float; 5. and (4) controlling the valve.
Detailed Description
In order to make the technical means, the creation characteristics, the achievement purposes and the effects of the utility model easy to understand, the utility model is further described with the specific embodiments.
As shown in figure 1, the constant-current dosing device for industrial sewage treatment comprises a medicine storage tank 1, a slide rail is arranged on the side wall of the medicine storage tank 1, a support 2 is connected to the side wall of the medicine storage tank 1 in a sliding mode through the slide rail, a buoy 4 is fixed on the support 2, and the buoy 4 drives the support 2 to move up and down together along with the change of the height of a liquid level. The support 2 is fixed with the hose 3, and 3 both ends of hose are water inlet 31 and delivery port 32 respectively, and water inlet 31 is located 1 inside of medicine storage tank and is located the liquid level below, and delivery port 32 is located 1 outsides of medicine storage tank, and water inlet 31 is higher than delivery port 32, and the difference in height between the two is invariable. This constant value ensures that the liquid is able to seep out, i.e. more than 1 cm. Meanwhile, the constant value does not need to be too large and can be controlled within 50 cm. The water outlet 32 of the hose 3 is also provided with a control valve 5.
It should be noted that the working principle of the constant-current dosing device for industrial sewage treatment of the utility model is as follows: in the device, a bracket 2 is connected on the inner wall of a medicine storage tank 1 in a vertical sliding way, when the liquid level in the medicine storage tank 1 moves up and down, the bracket 2 also moves up and down along with the liquid level under the action of a buoy 4,
the hose 3 also moves with the movement of the bracket 2. Since the height difference between the inlet 31 and the outlet 32 of the hose 3 is constant, the water pressure between the two ends is constant. By adopting the siphon method to discharge water, the liquid medicine can be dripped at a constant speed through the outer side end of the hose 3, namely the water outlet 32, and the dripping amount in unit time can also be kept constant. Further, the control valve 5 may be attached to the water outlet 32 to further control the dropping speed.
The foregoing shows and describes the general principles and broad features of the present invention and advantages thereof. It will be understood by those skilled in the art that the present invention is not limited to the embodiments described above, which are described in the specification and illustrated only to illustrate the principle of the present invention, but that various changes and modifications may be made therein without departing from the spirit and scope of the present invention, which fall within the scope of the utility model as claimed. The scope of the utility model is defined by the appended claims and equivalents thereof.
