A kind of impurity removing equipment for chicken house sewage disposal system isolation tank
Technical field
The utility model relates to chicken house environmental protection equipment, particularly relates to a kind of impurity removing equipment for chicken house sewage disposal system isolation tank.
Background technology
In chicken house environmental protection treatment engineering, sewage disposal is a very crucial link, determines the success or failure of whole chicken house environment-friendly engineering even to a certain extent.In technical scheme at present for chicken house sewage disposal, before microbiological treatment is carried out to sewage, need in sewage disposal system, to arrange isolation tank to tackle insoluble solid suspensions such as the chicken feathers in sewage, enter subsequent handling to prevent it thus affect the normal operation of subsequent technique.Traditional foreign material cleaning technology comprises following step: 1) first operating personnel clear up the foreign material of isolation tank sewage surface; 2) close isolation tank import, the mode of being inhaled by delivery port gravity flow mode and immersible pump pump drains the sewage in isolation tank; 3) operating personnel fasten safety rope, stand in above grid cleaning platform and carry out foreign material cleaning to grid; 4), after grid cleans out, enter under operating personnel in isolation tank and carry out foreign material cleaning.Adopt the method cleaning isolation tank to there is the problem of the following aspects: a) cleaning work need operating personnel stand in cleaning platform upper and lower enter isolation tank operation, there is larger potential safety hazard; B) each cleaning isolation tank all needs the sewage in isolation tank to empty, and have impact on the continuous operation of sewage disposal system; C) complex steps, labour intensity is large, production efficiency is low.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, provides that a kind of automaticity is high, labour intensity is low, safety coefficient is high, does not affect the impurity removing equipment for chicken house sewage disposal system isolation tank of the continuous operation of sewage disposal system.
In order to achieve the above object, the technical solution of the utility model is: a kind of impurity removing equipment for chicken house sewage disposal system isolation tank, comprise net-filter assembly and net-filter assembly elevating mechanism, described net-filter assembly comprise towards isolation tank water inlet intake gate, be located at the filter screen between isolation tank water inlet and delivery port and the base plate for accepting foreign material, described filter screen and described intake gate are all connected with described net-filter assembly elevating mechanism, and described base plate is fixedly connected with described filter screen.
As technique scheme further preferably: described base plate is rectangular base plate, and described filter screen comprises three metal filter plates, and described three metal filter plates and described intake gate are arranged along the surrounding of described rectangular base plate.
As technique scheme further preferably: described net-filter assembly hoisting mechanism comprises many hawsers, the hook be connected with described many hawser upper ends and the lifting pulley group that lower end is connected with described filter screen and described intake gate respectively, and described lifting pulley group is connected with described hook.
As technique scheme further preferably: described lifting pulley group is also equipped with drive motors.
As technique scheme further preferably: the pore diameter range of described filter screen is 5mm × 5mm to 10mm × 10mm.
Beneficial effect
Compared with prior art, the utility model has the advantage of: when utilizing impurity removing equipment removal of impurities disclosed in the utility model, first utilize net-filter assembly elevating mechanism by net-filter assembly lifting in isolation tank, open the intake gate of isolation tank water inlet and net-filter assembly, foreign material in sewage are isolated after entering net-filter assembly, fall on base plate, after operation a period of time (such as 24h), utilize net-filter assembly elevating mechanism to hang out in net-filter assembly self-isolation pond, operating personnel enter the eliminating impurities on base plate in net-filter assembly.The normal operation of sewage disposal system can be kept in whole process; Operating personnel enter in net-filter assembly and carry out cleaning work, very safe and reliable and step is simple, automaticity is high, labour intensity greatly reduces.
