Detailed Description

The present invention will be described in detail with reference to the accompanying drawings.

Example (b): a pipeline mixer is mainly used for adding medicaments in the sewage treatment process. As shown in fig. 1, the sewage treatment device comprises a body 1 and an adding pipe 2 arranged on the body 1, wherein a water inlet 11 and a water outlet 12 are respectively arranged at two ends of the body 1, an inlet flange 13 is arranged at the water inlet 11, an outlet flange 14 is arranged at the water outlet 12, and the pipeline mixer can be connected to the middle of a sewage treatment pipeline through the inlet flange 13 and the outlet flange 14. Sewage enters into body 1 from inlet flange 13 end, and the rethread adds pipe 2 and lets in medicament (like the flocculating agent) in body 1 to let the medicament can mix with sewage, reach the purpose that adds the medicament and mix.

In the process of adding the medicament, the inclination angle of the adding pipe 2 has a great influence on the actual adding amount of the medicament, and when the adding pipe 2 is arranged obliquely towards the sewage flowing direction, namely, one end of the adding pipe 2 far away from the body 1 is close to the outlet flange 14, the sewage in the body 1 has a tendency of rushing into the adding pipe 2, which causes the pressure of the added medicament to be large, so that the medicament is difficult to add. And when adding pipe 2 and deviating from the sewage flow direction slope and setting up, add pipe 2 and keep away from the one end of body 1 promptly and be close to import flange 13, at this moment, the flow in-process of sewage can form certain negative pressure and adsorb the medicament to adding pipe 2, and it is more convenient to add this moment, need not increase the add pressure of medicament by accident. Therefore, as shown in fig. 1 and 2, in the present embodiment, the addition pipe 2 is obliquely disposed in a direction away from the sewage flow direction.

In the flowing process of sewage, the stroke of adding the medicament is short, and the whole water flow is regular in the flowing process, so that after the medicament is added into the pipeline, the mixing degree is not high, and the actual action effect of the medicament is not obvious. In order to improve the mixing degree of the medicament, as shown in fig. 1 and 2, a spiral baffle 3 is arranged on the inner wall of a body 1, when sewage passes through the body 1, the sewage is blocked by the spiral baffle 3, and then the sewage flows along the spiral baffle 3 to spirally flow, so that a vortex is generated, and after the medicament enters the spiral baffle 3, the medicament is influenced by the vortex generated by the spiral of the sewage, so that the mixing degree of the medicament and the sewage is higher. And, spiral baffle 3 has the effect of blockking off that sewage flows, and then lets it mix more evenly when passing through body 1.

In the process that sewage flows through, the sewage flow in the middle of the body 1 is less influenced by the spiral baffle 3, so that the mixing uniformity of the medicament in the central position of the flowing water is less when the sewage is mixed. Therefore, in order to further sufficiently mix the waste water and the chemical, as shown in fig. 2 and 3, a mixing module 4 is provided inside the body 1, and the spiral baffle 3 is wound around the periphery of the mixing module 4. The mixing component 4 comprises a support frame 41 connected with the body 1 and a stirring blade 42 arranged on the support frame 41, wherein the outer diameter of the stirring blade 42 is smaller than the inner diameter of the spiral baffle 3. The supporting frame 41 includes a supporting rod 411 integrally connected to the body 1 and a rotating shaft 412 disposed at the axial center of the body 1, at least three supporting rods 411 are circumferentially and uniformly distributed on the rotating shaft 412, the rotating shaft 412 is more stably fixed at the axial center of the body 1, the stirring blade 42 is mounted on the rotating shaft 412, and the stirring blade 42 can rotate on the rotating shaft 412. During the use, combine to refer to fig. 2 and 5, sewage is direct towards stirring leaf 42 to drive stirring leaf 42 and rotate on axis of rotation 412, and then let sewage can slow down speed, can follow stirring leaf 42 simultaneously and rotate, and let it stir the mixture with the medicament that enters into in the body 1, let its mix more evenly. A waterproof bearing 43 may be installed between the stirring blade 42 and the rotating shaft 412 to facilitate the rotation thereof. In addition, a restricting cover 44 is attached to an end of the rotation shaft 412 in order to prevent the stirring blade 42 from coming off.

A fixing ring 413 is provided at an outer end (an end facing away from the rotation shaft 412) of the support rod 411, and is fixed to the main body 1 by the fixing ring 413, referring to fig. 2 and 4. The body 1 is provided with a fixing nail 5, the fixing nail 5 is connected with the body 1 by screw thread, and the fixing nail 5 is abutted against the fixing ring 413, so that the fixing ring 413 is fixed. The body 1 sets up bell mouth 15 in the position that sets up staple 5, sets up toper portion 51 simultaneously on staple 5, overlaps on toper portion 51 and establishes waterproof cover 6, and waterproof cover 6 sets up the toper structure, and waterproof cover 6 can directly adopt rubber materials to constitute, through the cooperation of bell mouth 15 with toper portion 51, lets waterproof cover 6 can seal the connection between staple 5 and the body 1.

The working principle is as follows: in inserting sewage treatment pipeline with body 1 through import flange 13 and export flange 14, add this body 1 with the medicament through adding pipe 2 in, rethread helical baffle 3 and stirring leaf 42 let sewage produce the effect of spiral and stirring, and then let medicament and sewage mix more evenly.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
