Improved sludge mixing device

Abstract

The invention discloses a sludge mixing device, which comprises a mixing vessel, a sludge feeding pipe, a chemical feed pipe and a sludge discharging pipe, wherein the position adjacent to the bottom of the mixing vessel on the side wall of the mixing vessel is provided with a sludge inlet, and the position adjacent to the top of the mixing vessel on the side wall of the mixing vessel is providedwith a sludge outlet; the sludge feeding pipe is connected with the sludge outlet and used for feeding the sludge to be treated into the mixing vessel; one end of the chemical feed pipe is communicated with parts of the sludge feeding pipe outside the mixing vessel and used for feeding chemicals into the sludge feeding pipe so as to deliver the chemicals to the mixing vessel by the sludge feedingpipe; and the sludge discharging pipe is connected with the sludge outlet and used for discharging the sludge. According to the sludge mixing device of the embodiment of the invention, under the action of negative pressures in the pipes, in the process of feeding the chemicals, the chemicals are delivered to the sludge feeding pipe by the chemical feed pipe, then the chemicals and the sludge are transmitted to the mixing vessel together to carry out a plurality of mixing, so that the mixing effect is preferable, and parts of energy consumption for transmitting the chemicals can be saved.

Description

technical field [0001] The invention relates to the field of sewage treatment, in particular to an improved sludge mixing equipment. Background technique [0002] In the field of sewage treatment, before dehydrating sludge, in order to improve the dehydration effect of sludge, it is necessary to add some chemicals to flocculate the sludge, so that the suspended matter in the sewage settles into sludge. The degree of mixing of chemicals and sludge will directly affect the effect of sludge flocculation and subsequent dehydration. [0003] The traditional sludge and chemical mixing equipment is a sludge conditioning tank, which is usually a square tank. The sludge and chemical enter the pool from the bottom of the pool, and the chemical is directly transported to the inside of the tank through a delivery pump, which consumes a lot of energy. Moreover, the mixing effect of the agent and the sludge is not very good. In addition, the mixing of medicament and sludge needs to be s...

Problems solved by technology

[0004] Therefore, the traditional sludge conditioning tank consumes a lot of energy, and because the stirring speed cannot be adjusted, the flocculated sludge is easily broken again, so the sludge flocculation is not complete and the mixing effect is not good.
