Embodiment 1

[0021] Such as figure 1 , figure 2 with image 3 As shown, the present invention includes a water inlet dosing pipe 1, a water medicine mixing pipe 2, an outlet pipe 3 and an impeller installation shaft 4;

[0022] A dosing pipe 1.1 is fixed on the water inlet dosing pipe 1; the left end of the impeller installation shaft 4 is fixedly connected with the left end of the water inlet dosing pipe 1 with a thread structure, and the right end of the impeller installation shaft 4 and the right end of the outlet pipe 3 are fixed with a thread structure connected;

[0023] The water-medicine mixing tube 2 includes three spiral tube installation pipes 2.3 and two connecting pipes 2.4, and the spiral pipe installation pipe 2.3 is composed of symmetrical two petals fixedly connected together by bolts not shown in the figure; the three spiral pipe installation pipes 2.3 and two connecting pipes 2.4 are alternately arranged and connected together with a flange structure. The left end o...

Embodiment 2

[0026] Such as Figure 4 As shown, the difference between Embodiment 2 and Embodiment 1 is mainly that the water-medicine mixing tube 2 of Embodiment 2 has an integral structure, and the three helical pipe bodies 2.1.1 adopt corresponding middle pipe sleeves 2.5 and end pipe sleeves 2.6 Separate positioning.

[0027] In addition to the structures described in the above embodiments, the spiral tube 2.1 can also be rolled and supported on the impeller installation shaft tube 4 through the corresponding connecting bracket and the impeller; or the impeller 2.2 can be rolled and supported together with the water through the corresponding connecting bracket and the spiral tube 2.1. Drug mixing tube on the 2 tube walls.

Abstract

The invention relates to the technical field of water treatment, and especially relates to a pipeline mixer which is applied to a flocculation deposition device and is used for fully mixing a flocculating agent with raw water. The pipeline mixer which can solve problems of low water-drug mixing efficiency and bad use reliability existing in the prior art has the advantages of simple structure, high use reliability and high water-drug mixing efficiency. The pipeline mixer which comprises a water-inlet drug-addition tube, a water-drug mixing tube and a water outlet tube is characterized in that: at least two spiral tube and impeller combinations which are promoted by the self power of a water flow are distributed in the channel of the water-drug mixing tube, and each spiral tube and impeller combination comprises a spiral tube and an impeller which is arranged on the spiral tube and is coaxial with the spiral tube; the spiral tube comprises a spiral tube body and several spiral blades fixed on the inner wall of the spiral tube body; the impeller comprises an impeller seat and several impeller blades fixed on the surface of the impeller seat; and the spiral direction of the spiral blades is opposite to the spiral direction of the impeller blades of a same spiral tube and impeller combination.

Description

technical field [0001] The invention relates to the technical field of water treatment, in particular to a pipeline mixer used in a flocculation and sedimentation device for fully mixing flocculant and raw water. Background technique [0002] In the flocculation and sedimentation device system of water treatment, a mixing device for flocculant and raw water is often installed on the raw water inlet pipe of the flocculation and sedimentation device, which is used to fully and uniformly mix the raw water and flocculant to form a microfloc before entering The main body of the flocculation-sedimentation device performs further flocculation-sedimentation treatment. [0003] The Chinese patent document published on January 27, 2010 with the publication number CN 201389362 and titled "Mixing reaction tube for coagulator for sewage treatment" discloses a mixing device for flocculant and raw water, which mainly "comprises The pipe body is characterized in that the pipe body is provi...
