Abstract

The invention relates to a novel flocculating agent and sludge mixing pipe which comprises a fixedly mounted pipe sleeve and a stirring shaft movably mounted in the pipe sleeve, wherein a spiral blade is arranged on the stirring shaft; the pipe wall of the pipe sleeve is provided with a hollow structure; a flocculating agent introduction pipe is mounted at one end of the pipe wall; through holes communicating with the inner cavity of the pipe wall are formed in the inner wall of the pipe sleeve in a spacing manner; the distances between every two adjacent through holes are gradually increased from the material feeding end to the material discharging end of the pipe sleeve; the outer wall of the pipe sleeve is of a conical structure; and the inner cavity of the pipe wall is gradually narrowed from the material feeding end to the material discharging end. By the adoption of pipeline tapering type introduction of a flocculating agent and sludge for mixing, the novel flocculating agent and sludge mixing pipe is good in mixing effect and high in speed, realizes continuous mixing and is high in efficiency.

Description

Novel flocculant and the mixing tube of mud

Technical field

The present invention relates to technical field of environment protection equipment, particularly to the processing means of mud.

Background technology

Before sludge dewatering, sludge conditioning to be carried out, so-called sludge conditioning is also referred to as the chemical conditioning of mud.Sludge condensation is general only Its moisture content can be made to drop to about 85%, moisture content will be reduced further, reduce volume it is necessary to separate out mud combines moisture Come, namely make this part water that the adhesive force of solid particle is weakened, make granule unstability grow up.Way generally used now is at mud Mud modulation pond is set before filter pressing, is used for mud carries out chemistry modulation, adds the organic-inorganic flocculant such as ferric chloride, Calx, The flocculant effect sludge flocculation time is typically at 5-10min.And mud modulation pond floor space and output investment ratio are relatively big, flocculant with The mixing of mud typically uses slow-speed of revolution dasher or Double-curved-surface stirring device, and mixed effect is undesirable.

Summary of the invention

The applicant, for the disadvantages mentioned above of prior art, studies and improves, it is provided that a kind of novel flocculant is mixed with mud Closing pipe, it uses tube wall to import the mode of flocculant, it is achieved flocculant and mud uniform, quickly mix, improve mixing and imitate Fruit and efficiency.

In order to solve the problems referred to above, the present invention uses following scheme:

A kind of mixing tube of novel flocculant and mud, including hard-wired pipe box and the shaft that is movably installed in pipe box, With helical blade on shaft；The tube wall of described pipe box is with hollow structure, and one end of described tube wall is provided with flocculant and imports Pipe, the inwall of pipe box is interval with and the through hole of tube wall inner space, the spacing between adjacent through-holes from the feed end end of pipe box to Discharge end is gradually increased, and the tapered structure of outer wall of described pipe box, the inner chamber of its tube wall is gradually reduced to discharge end from feed end.

The method have technical effect that:

The present invention uses pipeline gradual change type importing flocculant to mix with mud, and its good mixing effect, speed are fast, it is achieved continuously Mixing, efficiency is high.

Accompanying drawing explanation

Fig. 1 is the structural representation of the present invention.

In figure: 1, pipe box；11, feed end；12, discharge end；2, shaft；3, helical blade；4, flocculant imports Pipe；5, through hole.

Detailed description of the invention

Below in conjunction with the accompanying drawings the detailed description of the invention of the present invention is described further.

As it is shown in figure 1, the novel flocculant of the present embodiment and the mixing tube of mud, pacify including hard-wired pipe box 1 and activity The shaft 2 being loaded in pipe box 1, with helical blade 3 on shaft 2；The tube wall of pipe box 1 with hollow structure, tube wall One end is provided with flocculant ingress pipe 4, and the inwall of pipe box 1 is interval with the through hole 5 with tube wall inner space, adjacent through-holes 5 it Between spacing be gradually increased to discharge end 12 from the feed end end 11 of pipe box 1, the tapered structure of outer wall of pipe box 1, its tube wall Inner chamber be gradually reduced to discharge end 12 from feed end 11.

During use, mud is directed into pipe box 1 from the feed end 11 of pipe box 1, and flocculant imports pipe box from flocculant ingress pipe 4 In the tube wall of 1, derive from the through hole 5 of pipe box 1 inwall and mix with mud, drive spiral shell at shaft 2 (being driven by motor) Vane sheet 3 rotates and is sufficiently mixed under stirring；Due to the flocculant guide effect by through hole 5, progress in pipe box 1, Its good mixing effect, the uniformity is high；Pipe box 1 uses pyramidal structure, and the inner chamber of tube wall is that structure is reduced in gradual change, which ensure that wadding Solidifying agent imports pressure uniformly, thus improves mixed effect further.

Embodiment provided above is the better embodiment of the present invention, is only used for the convenient explanation present invention, not appoints the present invention What pro forma restriction, has usually intellectual, if without departing from the carried technical characteristic of the present invention in any art In the range of, utilize the Equivalent embodiments that the done local of disclosed technology contents is changed or modified, and without departing from this Bright technical characteristic content, all still falls within the range of the technology of the present invention feature.
