Abstract
The utility model relates to a sludge thickening and conveying system, characterized by: include concentrated pond, mud screw pump, store up the mud jar, stealthily defile pump and mud breaker, be connected with latent dirty pump on the concentrated pond, stealthily dirty pump is connected with the mud breaker, it is connected with the mud screw pump to store up the mud jar. Beneficial effect: the utility model discloses increased the breaker advancing the mud mouth, the big thing piece in the mud, plastics etc. Cut up, prevent the wearing and tearing of screw pump, the service life of the screw pump is prolonged, mud utilizes the immersible pump to promote to xiao chu mud jar by storing up the mud sump, reduces the location elevation of screw pump, work load, because mud has dwell time in storing up the mud jar, can make mud further concentrated, change the flow of screw pump into 20m3h, make the sheet frame advance the mud time contraction, reduce and produce the mud cycle, reduce energy consumption, mud cake moisture content.
Description
Technical field
The utility model belongs to sewage disposal device, particularly relates to a kind of sludge condensation and delivery system.
Background technology
Sludge condensation and delivery system, because storage basin pond holds little, scum silica frost residence time in storage basin that air flotation pool is discharged is very short, and the flow that every platform enters dredge pump is 12m
3/ h, what can not meet plate-and-frame filter press supplies mud demand, and storage basin sewage is easily excessive.Concentration basin is to the ground mounting height difference comparatively large (being about 4m) of spiral pump, and the processing power of spiral pump is 12m
3/ h cannot meet sludge dewatering equipment, causes storage basin sewage outflow, causes river course secondary pollution, directly affects influent quality; The liquid level of concentration basin is less than the mounting height of spiral pump.Spiral pump is caused not easily to inhale mud like this, i.e. enable suction mud, severe to the stator wear of spiral pump, reduce the work-ing life of spiral pump.Sludge crusher is lacked before spiral pump, if containing large thing block in mud, or plastics bag etc., easily cause the wearing and tearing of spiral pump, the more mud spiral pump that causes of storage basin energy foreign material often blocks, and causing stator, rotor often to damage affects the normal operation of sludge pump.Reduce its work-ing life.
Utility model content
The utility model is to overcome deficiency of the prior art, a kind of sludge condensation and delivery system are provided, mud can be delivered to plate-and-frame filter press, decrease the time that plate-and-frame filter press enters mud, reduce the infringement to equipment, thus ensure that the normal operation of following apparatus.
The utility model for achieving the above object, be achieved through the following technical solutions, a kind of sludge condensation and delivery system, it is characterized in that: comprise concentration basin, mud spiral pump, storage mud tank, submersible sewage pump and sludge crusher, described concentration basin is connected with submersible sewage pump, described submersible sewage pump is connected with sludge crusher, and described storage mud tank is connected with mud spiral pump.
Described mud spiral pump rear end is connected with dosing spiral pump by pipeline, and described dosing spiral pump rear end enters plate-and-frame filter press by pipeline connecting pipe road mixing tank.
Floating ball lever meter is equipped with in described storage mud tank.
The mud inlet diameter of described mud spiral pump is D80-D100, and the mud extraction pipe diameter of concentration basin is D100-D125.
Beneficial effect: compared with prior art, the utility model adds crusher at mud inlet, and the large thing block in mud, the choppings such as plastics, prevent the wearing and tearing of spiral pump; Improve the work-ing life of spiral pump, enter mudflow amount (12m due to what add spiral pump
3/ h is increased to 20m
3/ h), decrease the time that plate-and-frame filter press enters mud, increase work efficiency, mud utilizes submersible pump to be promoted to little Chu mud tank by storage basin, reduces the Installation Elevation of spiral pump, working load; Because mud has the residence time in storage mud tank, mud can be made to concentrate further, when inactive spiral pump, mud in spiral pump pipeline can be cleared up with backwashing pump; Change the flow of spiral pump into 20m
3/ h, makes sheet frame enter mud time shorten, reduces and produces the mud cycle, reduces energy consumption, moisture content of the cake; Set up dosing pump and add flocculation agent, mud and flocculation agent by the road mixing tank mix the flocculation concentration that takes a step forward that mud can be made to enter sheet frame.
Accompanying drawing explanation
Fig. 1 is connection block diagram of the present utility model.
Embodiment
Below in conjunction with preferred embodiment, to the embodiment provided according to the utility model, details are as follows: embodiment
Refer to accompanying drawing, present embodiments provide a kind of sludge condensation and delivery system, comprise concentration basin, mud spiral pump, storage mud tank, submersible sewage pump and sludge crusher, described concentration basin is connected with submersible sewage pump, described submersible sewage pump is connected with sludge crusher, and described storage mud tank is connected with mud spiral pump.Described mud spiral pump rear end is connected with dosing spiral pump by pipeline, and described dosing spiral pump rear end pipeline connects spiral pump rear end pipeline, and line mixer enters plate-and-frame filter press.Set up dosing spiral pump and add flocculation agent, mud and flocculation agent by the road mixing tank mix the flocculation concentration that takes a step forward that mud can be made to enter sheet frame.
(1) according to the specification (1.2 × 1.2) of every platform plate-and-frame filter press, totally 50 pieces of filter press plates and filter pressure 6 kilograms are derived and go out, and the mudflow amount of entering of the every platform spiral pump of the present embodiment is chosen as 20m
3/ h;
(2) volume is set up to be 1.5m on the ground
3small-sized storage mud tank, in concentration basin install 1 submersible sewage pump (Q=40m
3/ h), and in storage mud tank, a floating ball lever meter is installed, can control to be less than 10cm apart from storage mud pot bottom, then submersible sewage pump starts into mud, and apart from storage mud tank top 20cm, then submersible sewage pump stops into mud.
(3) before storage tank, arrange sludge crusher the large thing block in mud, the choppings such as plastics, prevent the wearing and tearing of spiral pump, extend its work-ing life.
(4) the mud inlet D80 of mud spiral pump, takes out pipeline and the mud extraction pipeline D100 of mud in addition from concentration basin.
Working process:
Start submersible sewage pump, mud extraction pool bottom sludge is promoted by submersible sewage pump, through crusher by choppings such as bulk refuse plastics, enter storage mud tank, in storage mud tank, floating ball lever meter is housed, the work of submersible sewage pump can be controlled, be less than 10cm apart from storage mud pot bottom, then submersible sewage pump starts into mud, apart from storage mud tank top 20cm, then submersible sewage pump stops into mud, ensures the operation of mud spiral pump.After starting mud spiral pump, be transferred to appropriate frequency by frequency transformer, to plate-and-frame filter press conveying mud, when line pressure reaches 0.6MPa, mud spiral pump is automatically out of service, treats that line pressure is down to below 0.6MPa, lowers frequency converter frequency, continues conveying mud; In addition, after unlatching mud spiral pump, open dosing spiral pump, utilize dosing spiral pump to add in pipeline by the certain density flocculation agent prepared in advance, through piping mixing tank after mixing with mud, concentrate further to reach mud, alleviate follow-up plate-and-frame filter press load, two spiral pump the using and the reserved, when switching spiral pump, opening backwashing pump and being cleaned out by the mud in spiral pump out of service and pipeline thereof.
Above-mentioned detailed description of this kind of sludge condensation and delivery system being carried out with reference to embodiment; illustrative instead of determinate; several embodiments can be listed according to institute's limited range; therefore in the change do not departed under the utility model general plotting and amendment, should belong within protection domain of the present utility model.
