Description

Medicine system and anaerobic jar

Technical Field

The utility model belongs to the field of sewage treatment, and particularly relates to a dosing system and an anaerobic tank.

Background

At present, in the sewage treatment process, the adding site of the phosphorus source is positioned in the acidification tank, so that the phosphorus source stays in the acidification tank for a longer time, the effect is deteriorated, and the using amount is increased.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned problems, it is an object of the present invention to provide a drug adding system capable of adjusting the amount of drug to be added according to a change in flow rate.

In order to achieve the purpose, the technical scheme of the utility model is as follows: the utility model provides a dosing system, includes transfer line, dosing pump and controller, be equipped with flow sensor and tee bend in proper order along liquid flow direction on the transfer line, the remaining interface of tee bend with the play medicine mouth intercommunication of dosing pump, the medicine inlet of dosing pump with add the interior intercommunication of medicine jar, dosing pump and flow sensor all with the controller electricity is connected.

The beneficial effects of the above technical scheme are that: therefore, the flow sensor can sense the flow in the infusion tube and adjust the flow of the liquid feeding pump according to the change of the flow in the infusion tube, so that the feeding amount of the liquid feeding pump can be flexibly changed in real time according to the flow in the infusion pump.

In the technical scheme, the dosing pump is a peristaltic pump.

The beneficial effects of the above technical scheme are that: thus, the corrosion of the medicine feeding pump caused by the liquid medicine can be avoided.

In the technical scheme, the two dosing pumps are arranged, the medicine inlets of the two dosing pumps are communicated with the inside of the medicine feeding tank, and the medicine outlets of the two dosing pumps are communicated with the rest interface of the tee joint.

The beneficial effects of the above technical scheme are that: thus, one dosing pump can be used as a working pump and the other dosing pump as a backup pump.

In the technical scheme, a valve is arranged at the communication position of the medicine outlet of the medicine feeding pump and the tee joint.

The beneficial effects of the above technical scheme are that: so can close the valve of the medicine outlet of the standby pump, and avoid the liquid medicine from flowing back to the medicine adding tank through the standby pump.

The utility model also aims to provide an anaerobic jar capable of flexibly regulating and controlling the addition amount of a phosphorus source.

The technical scheme of the utility model is as follows: the utility model provides an anaerobic jar, includes anaerobic jar body and as above medicine system, the exit end of transfer line with anaerobic jar body in-connection, the entrance point of transfer line is used for letting in the sewage after the preliminary treatment, in adding the medicine jar be used for storing phosphorus source liquid.

The beneficial effects of the above technical scheme are that: thus, the utilization rate of the phosphorus source can be improved.

FIG. 2 is a schematic diagram of a control circuit of the drug adding system according to embodiment 1 of the present invention;

FIG. 3 is a schematic view showing the structure of an anaerobic tank according to example 2 of the present invention.

In the figure: 1 dosing system, 11 infusion tubes, 12 dosing pumps, 13 controllers, 14 flow sensors, 15 tee joints, 16 dosing tanks, 17 valves and 2 anaerobic tank bodies.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

Example 1

As shown in fig. 1 and 2, this embodiment provides a medicine system, including transfer line 11, dosing pump 12 and controller 13, be equipped with flow sensor 14 and tee bend 15 along liquid flow direction on the transfer line 11 in proper order, the remaining interface of tee bend 15 with the play medicine mouth intercommunication of dosing pump 12, the medicine inlet of dosing pump 12 communicates in with the medicine jar 16, dosing pump 12 and flow sensor 14 all with controller 13 electricity is connected, so accessible flow sensor responds to the flow in the transfer line to change according to the flow in the transfer line adjusts the flow of dosing pump, makes the real-time nimble change of the volume of adding medicine of dosing pump according to the flow in the transfer line.

In the above technical scheme, the dosing pump 12 is a peristaltic pump, so that the dosing pump is prevented from being corroded by the liquid medicine.

In the above technical scheme, the dosing pump 12 is provided with two, two the medicine inlet of the dosing pump 12 is communicated with the interior of the dosing tank 16, and two the medicine outlet of the dosing pump 12 is communicated with the rest interface of the tee joint 15, so that one dosing pump can be used as a working pump, and the other dosing pump can be used as a standby pump.

In the above technical scheme, the connection between the medicine outlet of the medicine feeding pump 12 and the tee 15 is provided with the valve 17, so that the valve at the medicine outlet of the standby pump can be closed, and the liquid medicine is prevented from flowing back to the medicine feeding tank through the standby pump.

Wherein, the controller can adopt an arm series single chip microcomputer or a PLC controller.

Example 2

As shown in fig. 3, the present embodiment provides an anaerobic tank, including an anaerobic tank body 2 and a dosing system 1 as described in embodiment 1, wherein an outlet end of the infusion tube 11 is connected to the anaerobic tank body 2, an inlet end of the infusion tube 11 is used for introducing pretreated sewage, and a dosing tank 16 is used for storing a phosphorus source liquid, so as to improve a utilization rate of a phosphorus source.
