Description

Dot-dividing type depth adding of agent sludge pipe mixer
Technical field
The utility model relates to sewage disposal technology, especially a kind of dot-dividing type depth adding of agent sludge pipe mixing Device.
Background technique
Treatment of Sludge is one of most important link in entire wastewater treatment, in order to improve the solid content of sludge, sludge warp Often to pass through dehydration.Sludge dewatering generally adds flocculant before mechanical dehydration, be convenient for mechanical dehydration, to save water, It improves wastewater treatment efficiency and Treated sewage reusing plays an important role.Majority flocculant chemicals dosing plant is that chemical feed pipe is directly single at present Point adds medicament into sludge pipe, and medicament and sludge contact surface are limited, and the fluidised form of flocculant solution in the duct is single, leads It causes flocculant solution and sludge mixed effect bad, needs to reduce the moisture content of dewatered sludge by increase flocculant dosage, Cause medicament waste and moisture percentage in sewage sludge that cannot reach ideal value.
Utility model content
For above-mentioned deficiency in the prior art, the main purpose of the utility model is that solving existing at present in progress sludge When processing, there is a problem of that the medicament of dispensing and sludge mixed effect are bad, and a kind of medicament and sludge of can be improved is provided Mixability reaches the dot-dividing type depth adding of agent sludge pipe mixer for reducing moisture percentage in sewage sludge.
The technical solution of the utility model includes: dot-dividing type depth adding of agent sludge pipe mixer, which is characterized in that including The front end of mixing duct, the mixing duct is connected with sludge pipe, and the internal diameter of the mixing duct is greater than the interior of sludge pipe Diameter is equipped with screw thread on the inner wall of the mixing duct, the first drug feeding pipeline is connected in the front of mixing duct, in mixing tube The rear portion in road is connected with the second drug feeding pipeline, and first drug feeding pipeline and the second drug feeding pipeline are connected to mixing duct.
The mixer of the utility model when in use, directly passes through the first drug feeding pipeline and the second drug feeding pipeline to mixing tube Flocculant is added in road, since the installation site of two drug feeding pipelines is different, energy after flocculant enters in mixing duct It is enough adequately to be mixed with sludge, achieve the effect that quick, high-efficiency dehydration, additionally it is possible to the apparent usage amount for reducing flocculant, section Cost-saving.
Optimally, the diameter of the sludge pipe is 108mm, and the diameter of the mixing duct is 325mm.It is employed herein The bigger mixing duct of diameter, so that sludge can more fully be mixed in pipeline, is dehydrated, in conjunction with flocculant Time cycle is also longer.
Optimally, first drug feeding pipeline and the second drug feeding pipeline protrude into mixing duct, the first drug feeding pipeline The inner wall spacing of end and mixing duct is 50mm, and the end of the second drug feeding pipeline and the inner wall spacing of mixing duct are 100mm. The utility model is designed using the chemical feed pipe of different depth, so that flocculant can also be mixed in inside with sludge at middle part, Reach and further increased mixed effect, has accelerated the effect of dehydration.
Optimally, stainless steel spiral is welded on the mixing duct inner wall, mixed after the stainless steel spiral is fixed It closes and forms the screw thread in inner wall of the pipe.The utility model is conducive to simplify mixing tube by the way of installing stainless steel spiral The production in road, it is more convenient.
Compared with the existing technology, the utility model has the following beneficial effects:
The mixer of the present apparatus effectively increases flocculant solution by the spiral stream guidance slot structure in pipe and contacts with sludge Area is formed and is vortexed, not only change simultaneously because flocculant enters in pipe-line mixer from the toss area of 2 different depths respectively It has been apt to the mixed effect of medicament and sludge, and mixed liquor flows out in the shape of a spiral, rear end liquid in pipe can be driven to be formed in pipe Eddy flow, the fluid for promoting liquid and medicament and sludge to be mixed to form again efficiently mix, and improve the flowing speed of liquid in tube body Degree.By changing the fluidised form of flocculant solution and sludge inside pipeline, it is sufficiently mixed medicament and sludge uniformly, solves dehydration Moisture percentage in sewage sludge height and the high problem of flocculant unit consumption afterwards.After the present apparatus comes into operation, separate unit is respectively adopted, 2 desk centrifuges are flocculating Machine test, test result show dirt in desliming in 15 days by a definite date under the different situations that agent solution matched proportion density is 1 ‰, 2 ‰, 3 ‰ For mud moisture content minimum up to 77.4%, flocculant unit consumption declines nearly 5%.
