Abstract
The utility model discloses a sludge discharging system applied to a double-layer horizontal flow sedimentation tank. According to a tank body characteristic of the double-layer horizontal flow sedimentation tank, a siphon type sludge absorption machine is used for removing light-weight sludge in the sedimentation tank on the upper layer; and the problem that the light-weight sludge flies over easily by a bottom sludge scraper is solved. Furthermore, a reciprocating type (or single rail type) bottom sludge scraper is used for removing sludge in the sedimentation tank on the lower layer; a plurality of sludge discharging hoppers are arranged; the sludge scraping distance of the sludge scraper is shortened; the sludge scraping efficiency is improved; and the problems of low sludge scraping efficiency and unsuccessful sludge discharging are effectively solved. Moreover, by using two layers of sludge discharging trenches, the sludge in the sedimentation tank on the upper layer and the lower layer is discharged respectively through gravity and pressurization; the high-potential energy of the sludge in the sedimentation tank on the upper layer is effectively used; and the energy consumption is reduced. In conclusion, the sludge discharging system has the advantages of stability and reliability in running, high working efficiency and energy conservation and realizes the high-efficiency sludge discharging of the double-layer sedimentation tank.
Description
Technical field
The utility model is a kind of sludge drainage system that relates in the water engineering, specifically a kind of sludge drainage system that is applied to the double-deck horizontal sedimentation tank of water treatment plant.
Background technology
Advantages such as that horizontal sedimentation tank has is strong to raw water turbidity adaptability, treatment effect stable, cost is relatively low, convenient operation and management and construction are comparatively simple are extensively used by big-and-middle-sized water factory all the time.Yet along with the fast development of urban construction, the construction land utilized of large-and-medium size cities constantly reduces, and the construction site area of newly-built water factory engineering is often limited.Double-deck horizontal sedimentation tank has effectively improved treatment effeciency on the basis of inheriting common horizontal sedimentation tank advantage, reduced floor space, makes the less compact water factory of construction land adopt horizontal sedimentation tank to become possibility.Compare with common horizontal sedimentation tank, the sludge drainage system of two-storey settling tank is comparatively complicated, and traditional solution is that the bottom deposition is hung to the bucket of sedimentation basin one side enters the spoil disposal canal at two-layer uniform bottom set portion mud scraper up and down, and pump is to sludge treating system again.Because upper strata sedimentation basin mud is the lightweight flco, bottom mud scraper moves back and forth and has the problem of easily mud being kicked up, and influences effluent quality.Mud-removing bucket is scraped the mud distance in the end of sedimentation basin, and efficient is low, and the problem of spoil disposal difficulty easily takes place for sand content height, the higher silt of viscosity.In addition, after mud enters the spoil disposal canal, need again to pump by sludge pump, energy consumption is also bigger.
The utility model content
The purpose of this utility model is to provide a kind of efficient sludge drainage system that is applied to double-deck horizontal sedimentation tank.
To achieve these goals, the technical solution of the utility model is: a kind of sludge drainage system that is applied to double-deck horizontal sedimentation tank, described double-deck horizontal sedimentation tank comprises upper strata sedimentation basin and lower sediment pond, it is characterized in that the upper strata sedimentation basin arranges the hydrocone type suction dredge, the lower sediment pond arranges bottom mud scraper.Described sludge drainage system arranges double-deck spoil disposal canal, and the upper strata channel of hydrocone type suction dredge and double-deck spoil disposal canal is equipped with, and lower floor's channel of bottom mud scraper and double-deck spoil disposal canal is equipped with.The upper strata channel of double-deck spoil disposal canal is connected to sludge treating system through the gravity discharge pipeline.The lower sediment pond arranges bottom mud scraper at the bottom of the pond, and at least two mud-removing buckets of setting, described at least two mud-removing buckets are connected with lower floor's channel of double-deck spoil disposal canal, and described lower floor channel end is provided with the end bucket, and described end mud-removing bucket is connected to sludge treating system through the pressure discharge pipeline.The pressure discharge pipeline is provided with sludge pump.
The utility model adopts the hydrocone type suction dredge according to the characteristics of double-deck horizontal sedimentation tank at the upper strata sedimentation basin, discharges light weight sludge, has solved the problem that bottom mud scraper is easily kicked up mud; And at the bottom of pond, lower sediment pond, adopt reciprocating type (or monorail) bottom mud scraper, and many mud-removing buckets are set, effectively shortened the distance that mud transmits, solve single bucket and scraped the shortcoming that the mud distance is long, spoil disposal efficient is relatively low, effectively shortened the distance that mud transmits, further improved the effect of mud spoil disposal, it is more flexible that sedimentation basin is arranged, spoil disposal is more smooth and easy, and spoil disposal efficient is higher.The spoil disposal canal is set to two-layer up and down, lower floor's spoil disposal canal mainly is responsible for the deposition of discharging flocculation zone and sedimentation basin lower floor, upper strata spoil disposal canal then mainly is responsible for getting rid of the deposition of upper strata sedimentation basin, and directly is delivered to the spoil disposal water system by gravity, has effectively utilized the potential energy of upper strata mud.Equally, also can utilize upper strata spoil disposal canal gravity emptying during the emptying of upper strata sedimentation basin.This sludge drainage system efficiently solves the spoil disposal problem of two-storey settling tank, have stable, efficient work, energy-saving advantages.

The specific embodiment
The utility model will be further described below in conjunction with drawings and Examples.
The utility model is a kind of novel sludge drainage system that is applied to double-deck horizontal sedimentation tank, mainly comprises: hydrocone type suction dredge 1, bottom mud scraper 2, the first bottom mud-removing bucket 3, the second bottom mud-removing bucket 4, double-deck spoil disposal canal 5, spoil disposal canal end bucket 6, gravity discharge pipeline 7, sludge pump 8, pressure discharge pipeline 9.Sedimentation basin bottom deposition in upper strata drains into the upper strata channel of double-deck spoil disposal canal 5 by hydrocone type suction dredge 1, drains into sludge treating system through gravity discharge pipeline 7 then.The bottom deposition of lower sediment pond is pushed into the first bottom mud-removing bucket 3 and the second bottom mud-removing bucket 4 by reciprocating type (or monorail) bottom mud scraper 2, after mud reaches finite concentration in the mud-removing bucket, drain into lower floor's spoil disposal canal of double-deck spoil disposal canal 5, enter end mud-removing bucket 6 subsequently and drain into sludge treating system by sludge pump 8 through pressure discharge pipeline 9.
The utility model mainly has following characteristics:
Adopt the hydrocone type suction dredge to get rid of the upper strata light weight sludge, avoided light weight sludge to be kicked up by bottom mud scraper, and influenced effluent quality.
In addition, base plate arranges the multiple tracks mud-removing bucket in the lower sediment pond, and what effectively shortened reciprocating type (or monorail) bottom mud scraper scrapes the mud distance, has improved and has scraped mud efficient, has solved high sand content, the not smooth problem of high viscosity mud spoil disposal.
The 3rd, adopted double-deck spoil disposal canal, effectively utilized the potential energy of upper strata sedimentation basin mud, avoided high-order mud to fall the energy dissipation of back second lift.
