Abstract

A power-free external sand washing filter relates to a treatment device of sewage containing oil. The filter comprises a main tank body connected with a water feeding pipe and a water discharging pipe. The water feeding pipe is connected on the lower portion of the main tank body, and the water discharging pipe is connected at the top of the main tank body. A flow guide plate is arranged at the bottom in the main tank body, a flow guide tube is arranged at the top in the main tank body, and the upper portion of the main tank body is connected with a rotational flow sand removing washing tank. The rotational flow sand removing washing tank is connected with a backwashing water feeding pipe connected with a backwashing water feeding valve, and the water feeding end of the backwashing water feeding pipe is connected with the bottom of the main tank body. The top end of the rotational flow sand removing washing tank is connected with a backwashing water discharging pipe connected with a backwashing water discharging valve, and a pressure difference controller is connected between the backwashing water discharging pipe and the backwashing water feeding pipe. The power-free external sand washing filter is simple in structure, discharges water continuously, can conduct backwashing non-shutdown filtering, is low in water quantity, does not require external backwashing power, does not require a transmission mechanism or a stirring piece, and is safe and reliable in use and low in manufacture and management cost in the operation period. Filtering materials are not easy to harden.

Description

Unpowered external washed-out sand filter
Technical field
The utility model relates to the treating apparatus of oil-polluted water, particularly structure of filter.
Background technology
A kind of filter that can backwash is arranged in the prior art, primary structure comprises the circle tube tank body of upright setting, the top of tank body is provided with water inlet pipe, the bottom of tank body is provided with outlet pipe, be provided with upper spacer and lower clapboard in the tank body, set dividing plate is provided with some filter caps, is arranged between the upper spacer and lower clapboard in the tank body as the filtrate of filtering material with quartz sand etc.During work, sewage enters in the tank body from water inlet pipe, contacts with filtrate behind upper spacer, and filtrate can adsorb oil and other suspensions in the sewage, and the sewage that outlet pipe is discharged meets the requirements; After using after a while, filtrate can lose filtration because adsorbing too much oil or suspension, and filtration resistance is increased.At this moment, need to adopt the method for backwash to make media regeneration, when carrying out backwash, close the water-in and water-out valve, start backwash pump earlier filtrate is carried out the water flushing, restart blower fan filtrate is carried out gas flushing, make filtrate in backwash process, collide mutually, rub, after oil, suspension and filtrate be separated, the flushing water that carries big gauging and suspension left from the backwash outlet pipe, made filtrate obtain regeneration; Its weak point is: this filter can not move continuously; Adopt backwashing pump and blower fan to carry out backwash, energy consumption is big, and is not energy-conservation, do not meet the trend of present national energy-saving and emission-reduction; Because the backwash water-distributing device is difficult to guarantee that water distribution is even, will cause backwash inhomogeneous during backwash, the filtrate that does not flush is difficult to be become flexible, and hardens easily, influences filter effect, has reduced effluent quality.
Summary of the invention
The purpose of this utility model is in order to overcome the deficiencies in the prior art, the unpowered external washed-out sand filter that provides a kind of low cost of manufacture, continuously-running, filtrate to be difficult for hardening.
The purpose of this utility model is achieved in that unpowered external washed-out sand filter, comprise the great circle tubular master tank body of upright setting, in the main tank body filtrate is set, connect water inlet pipe and outlet pipe on the main tank body, described water inlet pipe is connected the bottom of main tank body, and outlet pipe is connected the top of main tank body; Bottom in the described main tank body arranges deflector, and the top in the main tank body arranges guide shell, connects the upright eddy flow desanding purge tank that arranges above main tank body, and eddy flow desanding purge tank is connected with guide shell; Connect the backwash water inlet pipe on the described eddy flow desanding purge tank, connect the backwash inlet valve on the backwash water inlet pipe, the water inlet end of backwash water inlet pipe is connected with the bottom of described main tank body; The top of described eddy flow desanding purge tank connects the backwash outlet pipe, connects the backwash flowing water Valve on the backwash outlet pipe, is connected differential pressure controller between backwash outlet pipe and the backwash water inlet pipe.
The utility model has two states in when work, and one is for filtering operating mode, and it two is the regeneration operating mode; Filtering under the operating mode, sewage enters in the tank body from the water inlet pipe of main tank body sidepiece, contacts with filtrate under the effect of deflector, and by filtrate is filtered, Jie Jing water is discharged outlet pipe in water collector relatively; When the pressure reduction between water inlet pipe and the outlet pipe is big, the filter effect that filtrate is described has reduced, need not close the outlet valve on the outlet pipe this moment, open backwash inlet valve and backwash flowing water Valve, under the effect of intake pressure, filtrate is brought in the eddy flow desanding purge tank, in this eddy flow desanding purge tank, produce eddy flow, make the oil and other suspensions that stick on the filtrate break away from filtrate, filtrate after the cleaning flows in the large cylinder shape tank body under the guiding of guide shell, oil and other suspensions that water outlet after the backwash is carried after the cleaning flow out by the backwash outlet pipe, and the filtrate after the flushing can recover filter capacity.This filter continuous filtration water outlet is uninterrupted, and what can guarantee to filter is continuously long-running.
Compared with prior art, the utility model is simple in structure, continuous effluent, and filtration is not shut down in backwash, low wash water, external backwash is unpowered, does not need transmission mechanism and stirring parts, and run duration is safe and reliable, and manufacturing cost and management cost are low, and filtrate is difficult for hardening.The utility model can be used in the sewage disposal of industries such as oil, petrochemical industry, electronics iron and steel, gardens, field irrigation, is used for filtering the sewage of oil-containing and other suspensions.
