Embodiment Construction

[0049] Combine below Figure 1 ~ Figure 2 The technical solution provided by the present invention is described in more detail.

[0050] see figure 1 and figure 2 , the embodiment of the present invention provides a drug dosing device, including a stirring tank 1 , a hopper 2 , a liquid delivery pipeline 3 , a first metering assembly 4 and a second metering assembly 5 .

[0051] The stirring tank 1 has a stirring chamber 1a. Stirring tank 1 is a component for realizing medicine preparation, and various medicine formulations are put into the stirring chamber 1a of stirring tank 1, and then stirred evenly to prepare required medicines. The mixing tank 1 is located below the hopper 2 and the liquid delivery pipeline 3 , and the hopper 2 and the liquid delivery pipeline 3 transport different kinds of materials to the mixing tank 1 respectively. For ease of distinction, the material in the hopper 2 is the first material, such as various medicines used for sewage treatment, suc...

Abstract

The invention discloses a dosing device and system, relates to the field of sewage treatment, and is used for accurately preparing drugs in a sewage treatment process. The embodiment of the invention provides the dosing device. The dosing device comprises a stirring tank, a hopper, a liquid conveying pipeline, a first metering assembly and a second metering assembly. The stirring tank has a stirring cavity; the hopper is provided with an accommodating cavity for storing a first material, and the accommodating cavity communicates with the stirring cavity of the stirring tank; the liquid conveying pipeline is configured to convey a second material of liquid, and the liquid conveying pipeline also communicates with the stirring cavity of the stirring tank; the first metering assembly is arranged on the hopper, and the first metering assembly is configured to weigh the weight of a first material conveyed by the hopper; and the second metering assembly is arranged on the liquid conveying pipeline, and the second metering assembly is configured to weigh the weight of the second material conveyed by the liquid conveying pipeline. According to the technical scheme, precise medicine preparation is achieved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to a dosing device and system. Background technique [0002] In the related technology, the sewage treatment station adopts the biochemical treatment method. Biochemical treatment uses anaerobic process or aerobic process to decompose and purify sewage. In the aerobic process, aerobic bacteria attach to the activated sludge to grow and reproduce. The activated sludge rolls along with the airflow in the aeration tank, and gradually enters the sedimentation tank in the next process. Since the specific gravity of activated sludge is close to that of water, in order to speed up the sedimentation or reduce the volume of the sedimentation tank, polymers, such as polyaluminum chloride or polyferric chloride, are usually added to the sewage after the aerobic process to treat the sludge in the sewage Flocculate for easy removal. [0003] The inventors found that there are at least the fol...
