Abstract

The invention relates to a flocculant mixing pipe for sludge treatment equipment. The flocculant mixing pipe comprises a fixedly installed pipe sleeve and a stirring shaft movably installed in the pipe sleeve, wherein the stirring shaft is provided with helical blades; the pipe wall of the pipe sleeve is provided with a hollow structure, one end of the pipe wall is provided with a flocculant introduction pipe, the inner wall of the pipe sleeve is provided with through holes at intervals which communicate with the inner cavity of the pipe wall, and the intervals between every two adjacent through holes gradually increase from the feed end to the discharge end of the pipe sleeve; and a plurality of guide rods are arranged in the pipe wall of the pipe sleeve, the end of each guide rod is provided with a guide motor, and the guide rods are symmetrically arranged around the central axis of the pipe sleeve. The pipeline gradual-change introduced flocculant is mixed with the sludge, so the mixing pipe has the advantages of favorable mixing effect, high speed and high efficiency, and implements continuous mixing.

Description

technical field

[0001] The invention relates to the technical field of environmental protection equipment, in particular to a sludge treatment device. Background technique

[0002] Before sludge dehydration, sludge conditioning should be carried out. The so-called sludge conditioning is also called chemical conditioning of sludge. Sludge concentration generally can only reduce the water content to about 85%. To further reduce the water content and volume, it is necessary to separate the bound water in the sludge, that is, to weaken the adhesion of this part of water to solid particles. Make the particles unstable and grow up. The common practice now is to set up a sludge conditioning tank before the sludge filter press to chemically condition the sludge, adding ferric chloride, lime and other organic and inorganic flocculants. The sludge flocculation time of the flocculants is generally 5- 10min. However, the sludge preparation tank occupies a relatively large area and in...

Embodiment Construction

[0010] The specific embodiments of the present invention will be further described below in conjunction with the accompanying drawings.

[0011] like figure 1 As shown, the flocculant mixing tube of the sludge treatment equipment of this embodiment includes a fixedly installed pipe sleeve 1 and a stirring shaft 2 movably installed in the pipe sleeve 1. The stirring shaft 2 has a spiral blade 3; the pipe sleeve 1 The pipe wall has a hollow structure, and one end of the pipe wall is installed with a flocculant introduction pipe 4, and the inner wall of the pipe sleeve 1 is provided with through holes 5 communicating with the inner cavity of the pipe wall at intervals, and the distance between adjacent through holes 5 is from the pipe wall. The feed end 11 of the sleeve 1 gradually increases toward the discharge end 12; a plurality of guide rods 6 are arranged in the pipe wall of the sleeve 1, and a guide motor 7 is installed at the end of the guide rod 6, and a plurality of guid...
