Tandem chemical feeding device

Abstract

The invention discloses a tandem chemical feeding device, comprising a cuboid-shaped liquid storage chamber, and a vertical first tank and a vertical second tank which are installed above the liquid storage chamber; two variable-speed motors are respectively and vertically arranged on the top ends of the first tank and the second tank; the inner parts of the first tank and the second tank are separately and vertically provided with a mixing blade capable of freely rotating; the mixing blades are respectively connected with the corresponding variable-speed motors in a way of transmission by means of a rotating shaft; a water inlet is formed in one side of the bottom of the first tank, and a water outlet is formed in one side of the bottom of the second tank; the water outlet is communicated, by a pipeline, with a water inlet of the liquid storage chamber arranged under the water outlet; a drain outlet is formed in one side of the liquid storage chamber; the first tank is communicated with the second tank by means of a bended connecting pipe; chemical feeding inlets are respectively formed in the tops of the first tank and the second tank. The tandem chemical feeding device can increase the mixed dissolution efficiency and solubility of chemicals while guaranteeing water yield.

Description

technical field [0001] The invention relates to a sewage treatment equipment, in particular to a series-type dosing device. Background technique [0002] Sewage discharge leads to serious pollution of water resources and living environment. In order to prevent the deterioration of this phenomenon, the water treatment industry has developed a variety of large-scale water treatment equipment to be used in the treatment of people's production and domestic sewage. The sewage discharged by many enterprises contains a large amount of refractory substances that cannot be effectively removed by a single water treatment equipment, so in many cases, it is necessary to reasonably add sewage treatment chemicals according to the particularity of the sewage water quality, so that the treated sewage meets the national discharge standards . Therefore, the general sewage treatment equipment is equipped with a dosing device for injecting drugs into the sewage, but the current dosing device i...

The sewage discharged by many enterprises contains a large amount of refractory substances that cannot be effectively removed by a single water treatment equipment, so in many cases, it is necessary to reasonably add sewage treatment chemicals according to the particularity of the sewage water quality, so that the treated sewage meets the national discharge standards

Therefore, the general sewage treatment equipment is equipped with a dosing device for injecting drugs into the sewage, but the current dosing device is only a simple tank, and it is difficult to fully mix the added medicine with the sewage, and the dissolution rate Slower and less soluble
