Description
Technical field
The utility model relates to a kind of waste liquid pool suction system, belongs to wastewater treatment equipment field.
Background technology
Waste liquid pool is the container that chemical plant, paper mill etc. easily produce that waste water enterprise is used for storing waste water, and general sink, in underground, in order to Large Copacity, needs excavation deep usually.When processing waste water, need to come cleanup system process from waste liquid pool waste water is aspirated, the aspirating pump that tradition adopts is diving pump, the motor of diving pump is placed on ground, output shaft extend in waste liquid pool, because waste liquid pool is deep, output shaft needs the very long water sucking mouth that could allow of doing enter bottom waste liquid pool, the output shaft of bottom cannot be effectively fixing, whole output shaft is caused to occur larger the rocking of amplitude like this, and impurity is more in waste water, easily there is the faults such as stuck in diving pump, diving pump dismounting is cumbersome, repair also more difficult, therefore in waste liquid pool suction system, adopt the system of this aspirating pump often to occur that various fault causes the longer maintenance interval.
Utility model content
The purpose of this utility model is to provide a kind of waste liquid pool suction system, by changing the type of aspirating pump and arranging corresponding auxiliary facility, output shaft need not be goed deep into bottom waste liquid pool, only need to work on the ground, output shaft can better be fixed, allow draw waste water more stablize and reduce noise, keep in repair convenient.
In order to achieve the above object, the technical solution adopted in the utility model is as follows: a kind of waste liquid pool suction system, comprise waste liquid pool, sewer pipe, water tank, centrifugal pump, described sewer pipe one end is communicated to bottom waste liquid pool, and the sewer pipe other end is communicated with the top of water tank, and the top of water tank is provided with gas valve, the bottom of water tank is communicated with the water sucking mouth of centrifugal pump, the water outlet of centrifugal pump is provided with boiler check valve, and described water tank is also provided with water injection pipe, and water injection pipe is provided with Water filling valve.
Preferably, the bottom of described water tank is also provided with foul valve.
Preferably, the blade wheel chamber of described centrifugal pump is connected with flushing pipe, and flushing pipe is provided with flushing valve.
Preferably, the current in described water injection pipe and described flushing pipe draw from same pipeline.
By adopting technique scheme, adopt centrifugal pump to replace original diving pump, pump machine only needs to install on the ground, facilitates staff to overhaul; Waste water in waste liquid pool absorbs by sewer pipe, without the need to water sucking mouth being stretched into bottom waste liquid pool by major axis, avoids major axis because of high speed rotating generation larger vibration noise.But because Ordinary Centrifugal Pumps does not possess suction capacity, therefore auxiliary facility is provided with accordingly, water tank is the major equipment producing negative pressure, virgin state keeps each valve closing, first open gas valve during initialization and (ensure that water tank inner air pressure does not uprise because of water filling, if do not open gas valve, then high pressure gas is known from experience by sewer pipe to waste liquid pool bottom direction discharge waste water, next step water tank is caused to form negative pressure) and Water filling valve, water filling in water tank, at least keep the water yield of tank body more than 1/2nd, then close gas valve and open centrifugal pump, centrifugal pump siphons away the clear water in water tank, negative pressure state is formed along with in the tank of minimizing gradually of clear water, waste water in waste liquid pool is pressed into water tank under atmospheric pressure, waste water just can be centrifuged pump and siphon away.Here sewer pipe is communicated with when the top object of water tank is to quit work at centrifugal pump; avoid the generation of siphonage; although have boiler check valve and gas valve to ensure the leak tightness of water tank; but in lengthy shut down process, there is Leakage Gas unavoidably; cause the waste water in water tank gradually because siphon action flows back to waste liquid pool; follow-up when reworking again again by water injection pipe injected clear water; therefore the top that sewer pipe is arranged on water tank be ensure that the high water level state in water tank, avoid waste water refluence can waste liquid pool.

Detailed description of the invention
A kind of waste liquid pool 1 suction system, comprise waste liquid pool 1, sewer pipe 2, water tank 3, centrifugal pump 4, sewer pipe 2 one end is communicated to bottom waste liquid pool 1, sewer pipe 2 other end is communicated with the top of water tank 3, the top of water tank 3 is provided with gas valve 5, and the bottom of water tank 3 is communicated with the water sucking mouth of centrifugal pump 4, and the water outlet of centrifugal pump 4 is provided with boiler check valve 6, the top of water tank 3 is also provided with water injection pipe 7, and water injection pipe 7 is provided with Water filling valve 8.Adopt centrifugal pump 4 to replace original diving pump, pump machine only needs to be arranged on ground 12, facilitates staff to overhaul; Waste water in waste liquid pool 1 absorbs by sewer pipe 2, without the need to water sucking mouth being stretched into bottom waste liquid pool 1 by major axis, avoids major axis because of high speed rotating generation larger vibration noise.But because Ordinary Centrifugal Pumps 4 does not possess suction capacity, therefore auxiliary facility is provided with accordingly, water tank 3 is the major equipments producing negative pressure, virgin state keeps each valve closing, first open gas valve 5(during initialization and ensure that water tank 3 inner air pressure does not uprise because of water filling, if do not open gas valve 5, then high pressure gas is known from experience by sewer pipe 2 to waste liquid pool 1 bottom direction discharge waste water, next step water tank 3 is caused to form negative pressure) and Water filling valve 8, water filling in water tank 3, at least keep the water yield of tank body more than 1/2nd, then close gas valve 5 and open centrifugal pump 4, centrifugal pump 4 siphons away the clear water in water tank 3, negative pressure state is formed along with in the tank of minimizing gradually of clear water, waste water in waste liquid pool 1 is pressed into water tank 3 under atmospheric pressure, waste water just can be centrifuged pump 4 and siphon away.Here sewer pipe 2 is communicated with when the top object of water tank 3 is to quit work at centrifugal pump 4; avoid the generation of siphonage; although have boiler check valve 6 and gas valve 5 to ensure the leak tightness of water tank 3; but in lengthy shut down process, there is Leakage Gas unavoidably; cause the waste water in water tank 3 gradually because siphon action flows back to waste liquid pool 1; follow-up when reworking again again by water injection pipe 7 injected clear water; therefore the top that sewer pipe 2 is arranged on water tank 3 be ensure that the high water level state in water tank 3, avoid waste water refluence can waste liquid pool 1.
Preferably, the bottom of water tank 3 is also provided with foul valve 9.Because in waste water, impurity is many, bottom water tank 3, easily deposition causes the water sucking mouth blocking centrifugal pump 4, arrange foul valve 9 impurity of deposition in water tank 3 to be discharged, the valve of water injection pipe 7 is opened above best when impurities removal, energy blowdown is more thorough, plays the object of cleaning water tank 3 simultaneously.
Preferably, the blade wheel chamber of centrifugal pump 4 is connected with flushing pipe 10, and flushing pipe 10 is provided with flushing valve 11.The impeller of centrifugal pump 4 is waste water due to what draw, and the inside miscellaneous affair is many, arranges flushing pipe 10 pairs of blade wheel chamber and recoils, then discharge impurity by foul valve 9, makes centrifugal pump 4 because blocking repairs convenient.
Preferably, water injection pipe 7 draws from same pipeline with the current in flushing pipe 10.Such design facilitates the arrangement of pipeline, and the material of water injection pipe 7 can select the rubber tube that diameter is relatively little, does not affect space hold.
