Description

A kind of centrifugal sludge concentrator

Technical field

The present invention relates to a kind of Centrifugal sludge dehydration equipment, especially a kind of centrifugal sludge concentrator.

Background technique

Sludge solid content is lower than 1%, and direct sludge dewatering effect is undesirable, and flocculant increase in demand.As concentration is lower than 1% domestic sludge or sticky industrial sludge enter belt filter press and will lead to leakage mud, press not mud extraction, treatment effeciency is low, mud cake Thin, moisture content of the cake is high.Traditional way is that civil engineering increases sludge concentration tank.But it takes up a large area, long processing period, low efficiency Under.

Summary of the invention

It is an object of the invention to overcome above-mentioned the deficiencies in the prior art, a kind of centrifugal sludge concentrator is provided, with dirt The sludge of medicament early period conditioning glue plumage is imported centrifugal sludge concentrator and screened out in separating barrel fine screen mesh by dredge pump, to rotate at a slow speed A large amount of upper liquids are filtered out after seething, board is improved to reach concentration reduction functions using the form of semi-centrifugal type rotating filter Processing energy simultaneously shortens the operation processing time.It carries out in entire thickening system into mud, dosing, mixing, reaction, wet mud The pile line operations such as output.Process flow are as follows: concentration basin sludge, sludge conditioning stir evenly, centrifugal drainage screens out separation, dense Contracting sludge enters the further dehydration of dewaterer afterwards.After preliminary hydro-extraction is concentrated, sludge concentration is greatly improved, and is particularly suitable for Filter-press dehydration process is carried out into belt filter press, avoiding leads to the case where leaking mud because sludge concentration is too low.In some sewage Amount is big, sludge solid content is low as domestic sludge, starch biochemical sludge are widely used.

In order to achieve the above objectives, the technical scheme is that a kind of centrifugal sludge concentrator, including cylinder, mistake Water tank, bracket one, thickener, the cylinder top left side set mud inlet, and right side sets stirring motor, and the stirring motor axis is stretched Fixation agitating shaft sets stirrer paddle, sets water strainer, the mistake among cylinder and excessively water tank in cylinder on the agitating shaft Water pipe is set at bottom on front side of water tank, sets bracket one below, and one or four footing of the bracket respectively set a plain cushion one, set on the left of cylinder Dredging tube, the dredging tube outlet end connect among centrifugal dehydration idler wheel, and told centrifugal dehydration idler wheel is located in thickener, and side is set Motor connects, and sets the upper cover that can be turned on the thickener, right side sets control electronic box, and the control electronic box is fixed on the electricity divided into On box bracket, concentration motor spindle divides into bucket, and the bucket bottom sets water pipe, sets mudhole on the left of thickener, divide into bracket two, Two or four footing of the bracket are respectively provided with plain cushion two.

The beneficial effects of the present invention are: the sludge of medicament early period conditioning glue plumage is imported centrifugal sludge condensation with sludge pump In machine cylinder, is rotated at a slow speed with stirring motor drive stirrer paddle and filter out a large amount of upper liquids after seething, using semi-centrifugal type The form of rotating filter, to reach concentration reduction functions, moisture crosses water tank by what water strainer inflow was divided into, and is arranged by downcomer Out, it tentatively improves board processing energy and shortens the operation processing time；Sludge after preliminary hydro-extraction enters centrifugation through dredging tube and takes off Water idler wheel, the concentration of rotary and centrifugal type second dehydration, sludge concentration greatly improve, and are particularly suitable for entering belt filter press progress filters pressing Dehydration procedure, avoiding leads to the case where leaking mud because sludge concentration is too low.Some sewage quantities are big, sludge solid content is low such as life Work sludge, starch biochemical sludge are widely used.
