Abstract
A filter with a double-layer filter material is mainly a filtering device used for water treatment of clear water, sewage, and oil-containing sewage and the like. The filter includes a pot body, a lower supporting assembly, an upper-layer filter material and a lower-layer filter material. A water inlet is disposed on an upper end of the pot body and a water outlet is disposed on a lower end of the pot body. The lower supporting assembly is fixed on a lower part of an inner side of the pot body. The upper-layer filter material and the lower-layer filter material are respectively stacked on the lower supporting assembly. A filter material stirring and raking device is arranged above the upper-layer filter material and is fixedly supported on the pot body. By means of a tooth rake installed on a rotating arm in the filter, the filter material on a top layer of the filter is stirred and cleaned, thereby ensuring the filter material to be cleaned completely and enabling a surface of the filter material to be level.
Description
Technical field
The present invention is mainly a kind of for filter plants such as water treatment clear water, sewage, oil-polluted waters.
Background technology
Two-layer filter needs to clean after filtration a period of time at present, backwash is normal washing, the washing+air purge of adopting at present, during due to filtration, filtrate top layer filtrate pollutes more serious, conventional cleaning way can not carry out power friction cleaning to top filtrate, filtrate can not reach regeneration thoroughly, because filtrate motion in the time cleaning is irregular, top layer filtrate can not recover level after cleaning simultaneously.
Summary of the invention
In order to address the above problem, the invention provides a kind of Two-layer filter.
The present invention includes tank body, lower supporting assembly, upper strata filtrate, lower floor's filtrate, the upper end of described tank body arranges water inlet, the lower end of described tank body sets out the mouth of a river, described lower supporting assembly is fixed on described tank body lower inside, described upper strata filtrate, lower floor's filtrate are deposited in respectively on described lower supporting assembly, above the filtrate of described upper strata, filtrate is set and turns over rake device, described filtrate turns over rake device and is fixedly supported on described tank body.
Filtrate of the present invention turns over rake device and comprises reductor, rotating shaft, turning arm, tooth harrow, described reductor is fixedly supported on described tank body top, one end of described rotating shaft is connected to the output of described reductor, described rotating shaft and described tank body coaxially arrange, the other end of described rotating shaft is fixedly connected with described turning arm, described turning arm is vertical with described rotating shaft, and described tooth harrow is fixedly connected on described turning arm, between described rotating shaft and described tank body, mechanical seal is set.
Lower supporting assembly of the present invention is a supporting screening plate, and described supporting screening plate is fixed on described tank body lower part.
When normal filtration work of the present invention, water flows into from top water inlet, and bottom delivery port flows out, and when reaching certain filtration time, pollutant dams in filter material surface and inside, and now filtrate need to clean.When cleaning, rinse water flows into from bottom delivery port, and the bed of material drives pollutant to flow out from the upper stepping mouth of a river after filtration; This equipment adopts the auxiliary cleaning equipment of a kind of rotation tooth harrow, drive the turning arm being arranged on rotating shaft by reductor, by the tooth harrow being arranged on turning arm, filter top metafiltration material is stirred to scouring, ensure that filtrate cleans thoroughly, filter material surface recovers level; It is not thorough that this set solves the filtrate cleaning in the time adopting conventional cleaning way of current double-layer filter material, the shortcoming of filter material surface injustice.
Brief description of the drawings
Fig. 1 is a kind of structural representation of the present invention;
Fig. 2 is that the A-A of Fig. 1 is to view.
Detailed description of the invention
As shown in Figure 1, this Two-layer filter, comprise tank body 1, lower supporting assembly 4, upper strata filtrate 2, lower floor's filtrate 3, the upper end of tank body 1 arranges water inlet 5, the lower end of tank body 1 sets out the mouth of a river 6, and lower supporting assembly 4 is fixed on tank body 1 lower inside, and upper strata filtrate 2, lower floor's filtrate 3 are deposited in respectively on lower supporting assembly 4, filtrate is set above upper strata filtrate 2 and turns over rake device 12, filtrate turns over rake device 12 and is fixedly supported on tank body 1.
Preferably, filtrate turns over rake device 12 and comprises reductor 7, rotating shaft 9, turning arm 10, tooth harrow 11, reductor 7 is fixedly supported on tank body 1 top, one end of rotating shaft 9 is connected to the output of reductor 7, rotating shaft 9 coaxially arranges with tank body 1, and the other end of rotating shaft 9 is fixedly connected with turning arm 10, and turning arm 10 is vertical with rotating shaft 9, tooth harrow 11 is fixedly connected on turning arm 10, between rotating shaft 10 and tank body 1, mechanical seal 8 is set.
Preferably, lower supporting assembly 4 is a supporting screening plate 13, and supporting screening plate 13 is fixed on tank body 1 bottom, and gripper shoe 13 is fixing by brace rod 14.
