Description

A medicament mixing arrangement for vacuum preloading tail water treatment

Technical Field

The utility model relates to an environmental protection equipment field especially relates to a medicament mixing arrangement for vacuum pre-compaction tail water treatment.

Background

With the rapid development of economy, a lot of urban industrial and domestic wastewater is directly discharged into rivers, so that serious pollution is caused to the water quality of lakes and rivers, and serious environmental problems can be caused when pollutants in sediment are accumulated seriously to a certain extent. The treatment of the river channel is an important and effective measure for eliminating the endogenous pollution besides source control and sewage interception, wherein the dredging of the river channel is the most important means for eliminating the endogenous pollution of the water body. The river channel dredging is the whole process of cutting, collecting, extracting and conveying sludge in a water body from the water bottom to a specific place for centralized treatment. The tail water needs to be treated after the river channel is desilted.

The vacuum preloading method is generally applied to the treatment of soft foundation, and is a foundation treatment method which comprises the steps of arranging a vertical plastic drainage plate in soft clay, covering a thin film for sealing, exhausting air to enable the interior of the thin film to be in a partial vacuum state so as to remove water in soil, and solidifying the soil so as to reduce the later settlement of the foundation. At present, vacuum preloading is a relatively rare mode in the desilting field.

There is a need for a device capable of treating tail water after sludge discharge by a vacuum preloading method.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem, the utility model provides a medicament mixing arrangement for vacuum pre-compaction tail water treatment. Use the utility model discloses afterwards, can make tail water and medicine intensive mixing and obtain effective processing.

The utility model discloses the technical scheme who adopts as follows:

a medicament mixing device for vacuum preloading tail water treatment comprises a cofferdam and a mixing pool, wherein one side of the mixing pool is abutted to the cofferdam, the pool bottom of the mixing pool is lower than the upper surface of the cofferdam, a baffle is arranged on the other side of the mixing pool, and twelve steel pipes sequentially penetrate through the baffle along the horizontal direction; the plurality of supports stretch across and are arranged between the cofferdam and the baffle, two pipelines are arranged on the supports, a plurality of medicine outlet holes are formed in the outer surfaces of the pipelines, one end of each pipeline is connected with the medicine dispensing box, and the other end of each pipeline is closed.

It is further characterized in that:

one side of the cofferdam abutted to the mixing pool is vertically arranged relative to the horizontal plane;

a dosing pump is arranged on each pipeline close to the dosing box;

the support comprises a pillar and a cross beam, and the cross beam is higher than the upper surface of the cofferdam;

the medicine outlet holes between the two pipelines are mutually staggered;

the steel pipe is arranged at the lower part of the baffle;

the baffle is vertically arranged relative to the horizontal plane;

the opening directions of the medicine outlet holes in the pipelines are consistent;

the opening directions of the medicine outlet holes in the pipelines are opposite.

The utility model has the advantages as follows:

use the utility model discloses afterwards, because one side of cofferdam and mixed pond butt is perpendicular setting for the tail water is parabola shape and gets into mixed pond, and the tail rivers of whereabouts can arouse the stirring of tail water in the mixed pond like this, promotes that the tail water and the interior existing medicament of mixed pond must mix.

Due to the arrangement of the baffle and the steel pipe, the tail water can only flow out through the steel pipe, so that mixed flow and speed reduction are generated in the tail water mixing pool, the retention time of the tail water in the mixing pool is prolonged, and the tail water is better mixed with the medicine.

The medicine outlet holes which are arranged on the two pipelines in a staggered mode can also ensure that the medicine and tail water in the mixing tank are fully mixed, the medicine and the tail water can be mixed and act to the maximum extent, and preparation is made for subsequent treatment.

Wherein: 1. cofferdam; 2. a dosing pump; 3. a mixing tank; 4. a support; 41. a cross beam; 42. a pillar; 5. a pipeline; 51. a medicine outlet hole; 6. a baffle plate; 7. a steel pipe; 8. a dosing box.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings.

A medicament mixing arrangement for vacuum preloading tail water treatment, it includes cofferdam 1 and mixing pool 3, mix pool 3 and fix to one side of the cofferdam 1 and pool bottom lower than the upper surface of the cofferdam 1, one side of the cofferdam 1 and mixing pool 3 is perpendicular to horizontal plane, another side of the mixing pool 3 sets up the baffle 6 perpendicular to horizontal plane, there are twelve round steel pipes 7 that are in the same horizontal plane, diameter 600mm to run through the baffle 6 in the lower part of the baffle 6, the support 4 includes crossbeam 41 and pillar 42, the support 4 spans and sets up between baffle 6 and the cofferdam 1, the crossbeam 41 is higher than the upper surface of the cofferdam 1, set up two pipelines 5 on the support 4, set up the dosing pump 2 close to 8 on two pipelines 5, offer a discharge hole 51 every 10cm on the pipeline 5, discharge hole 51 on two adjacent pipelines 5 are staggered each other and identical in the direction of opening, the one end of the pipeline 5 connects the dosing tank 8, the other end is closed.

Use the utility model discloses the time, at first dispense in the medicine chest 8, add on the pipeline 5 medicine pump 2 and close, treat that the tail water flows into from cofferdam 1 and mixes after 3 in the pond and open and add medicine pump 2, because the other end of pipeline 5 seals, so the medicament can only be followed and respectively go out the fine impurity intensive reaction that the blowout got into in medicine hole 51 and mix pond 3 and the tail water. The tail water enters the mixing pool 3 in a parabolic shape after passing through the cofferdam 1, and the falling tail water can stir the tail water in the mixing pool 3 and also can play a role in promoting the tail water to be mixed with the existing medicament in the mixing pool 3. Because baffle 6 and steel pipe 7's setting for the tail water can only flow through steel pipe 7, make the tail water produce the mixed flow and the deceleration in mixing tank 3 like this, increase the time that the tail water dwells in mixing tank 3, thereby mix with the medicine better, the medicine hole 51 of setting up in turn on two pipelines 5 also can guarantee medicine and the tail water intensive mixing in mixing tank 3, the at utmost guarantees medicine and tail water and mixes and produce the effect like this, prepares for subsequent processing.

The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made within the scope of the invention.
