Description

A kind of screening and sieving apparatus for water treatment

Technical field

The present invention relates to a kind of water treatment facilities, especially a kind of screening and sieving apparatus for water treatment.

Background technology

In sewage disposal process, for reaching state sewage emission standard, general sewage all adopts the flow process of one-level physical treatment to secondary biochemical treatment, and before entering biochemical treatment, sewage all will pass through multiple tracks physical separation processes unit such as coarse rack, fine fack, settling pit, preliminary sedimentation tank.Wherein coarse rack, fine fack are mainly removed suspension bigger in the sewage, floating thing, fiber goods and materials and solid particulate matter; Settling pit, inorganic particle and suspension that the main partition density of preliminary sedimentation tank is bigger are to guarantee the normal operation of subsequent treatment unit and water pump.The treatment facility of the various physical separation of prior art in sewage treatment project is single processing unit equipment, each processing unit all need have special equipment supporting, and need corresponding structures, cause equipment input, land use area, civilwork engineering quantity all bigger, and operational efficiency is low.

At present, both at home and abroad traditional wastewater is handled and taked various corrective measures, Chinese patent 85103329 discloses a kind of squeezing constitute filter of rotating continuous sediment-cleaned, its mainly be to waste residue and water separate and certain effect has been played in the discharge of waste residue, but in the face of sewage water filtration is handled, still also have a lot of problems to need to solve, big as space hold, the equipment input amount is big, the ancillary works amount is big, efficient is low etc.

Summary of the invention

The objective of the invention is to overcome the unicity of equipment in the existing sewage disposal, a plurality of processing unit functions are merged, raise the efficiency, save the space.Technical scheme of the present invention is so to realize:

A kind of screening and sieving apparatus for water treatment, comprise deslagging device (24), slag-draining device (12), casing (4), frame (21) and tank (22) provided thereon, tank (22) both sides are provided with water inlet (1) and delivery port (13), as preferably, deslagging device (24) is " factory " shape structure, the one end is inclined in the tank (22), and the other end links to each other with slag-draining device (12).

As preferably, described deslagging device (24) is to be provided with " factory " shape support (6) of drive roll (10) and driven cylinder (25) and to be located at its peripheral filter cloth (5) and to form by two ends, and " factory " shape support (6) bending part is provided with the back-up roller (26) of adjustable filter cloth (5) degree of tightness.

As preferably, described slag-draining device (12) is located at deslagging device (24) slag output end below, system is made up of motor (14), conveying worm (23), slag notch (19) and the press cylinder (18) that links to each other with conveying worm (23) tail end, and conveying worm (23) tail end is provided with its peripheral filter cloth (17) of parcel, nozzle (16) and pressing filtering liquid outlet (20).

As preferably, water inlet (1) one side of described tank (22) is provided with fluid level indicator (3) and overflow lip (2).

As preferably, nearly drive roll (10) end of described support (6) is provided with air blow off device (9) and spatula (11).

As preferably, the support (6) that described air blows off between device (9) and the back-up roller (26) is provided with nozzle (8).

The present invention has mainly overcome the unicity of physical separation functions of the equipments in the existing sewage disposal, with the function merging of traditional a plurality of processing units.This equipment can be with the disposable physical separation of effectively carrying out of sewage, can carry out filter-press dehydration to isolated filtrate again, effectively reduce the volume of filtrate, wherein the filter cloth in the filtration system has commutativity, can require to select filter cloth according to raw water quality and water outlet, make this device have very strong adaptability.Air blows off being provided with of device (9) and spatula (11) can be to effectively blowing off attached to the filtrate on the filter cloth (5) and striking off, being provided with of nozzle (8) can be washed rectification to filter cloth (5), recover filtering function, make it have self-cleaning and self-regeneration function.Characteristics such as compared with prior art, the present invention has compact conformation, floor space is little, applied widely, cost is low, operational efficiency height.

Description of drawings

Accompanyingdrawing 1 is a kind of structural representation of the present invention;

Accompanyingdrawing 2 is that the A-A of accompanyingdrawing 1 is to view.

The specific embodiment

Below in conjunction with accompanying drawing,, technical scheme of the present invention is described in further detail by embodiment.

Embodiment: with reference to the accompanyingdrawings 1, accompanyingdrawing 2, a kind of screening and sieving apparatus for water treatment, comprise deslagging device (24), slag-draining device (12), casing (4), frame (21) and tank (22) provided thereon, tank (22) both sides are provided with water inlet (1) and delivery port (13), deslagging device (24) is " factory " shape structure, the one end is inclined in the tank (22), and the other end links to each other with slag-draining device (12).Deslagging device (24) is to be provided with " factory " shape support (6) of drive roll (10) and driven cylinder (25) and to be located at its peripheral filter cloth (5) and to form by two ends, and " factory " shape support (6) bending part is provided with the back-up roller (26) of adjustable filter cloth (5) degree of tightness.Nearly drive roll (10) end of support (6) is provided with air blow off device (9) and spatula (11).The support (6) that air blows off between device (9) and the back-up roller (26) is provided with nozzle (8).Slag-draining device (12) is located at deslagging device (24) slag output end below, system is made up of motor (14), conveying worm (23), slag notch (19) and the press cylinder (18) that links to each other with conveying worm (23) tail end, and conveying worm (23) tail end is provided with its peripheral filter cloth (17) of parcel, nozzle (16) and pressing filtering liquid outlet (20).Water inlet (1) one side of tank (22) is provided with fluid level indicator (3) and overflow lip (2).

During work, sewage enters the tank (22) from water inlet (1), overflow lip (2) and fluid level indicator (3) are in order to control and regulate flow of inlet water and liquid level, when the flow of sewage access arrangement surpasses its disposal ability, part of contaminated water will be overflowed from overflow lip (2), flow into water inlet (1) again by pipeline.Air enters from the air inlet (7) on the casing (4).After motor (15) operation, drive drive roll (10) by transmission system and clockwise rotate, filter cloth (5) overlays on drive roll (10), driven cylinder (25) and the back-up roller (26) and rotates together.Water after filter cloth (5) diafiltration is discharged by delivery port (13).After filter cloth (5) forwards the position of drive roll (10) to, part on the filter cloth freely drops in the conveying worm (23) of below because of conducting oneself with dignity than the big filter waste residue, remove by spatula (11) and the air device (9) that blows off attached to the less filtrate on the filter cloth (5), the filter residue that removes can freely fall in the conveying worm (23), and high pressure nozzle (8) washes rectification to filter cloth (5) subsequently.Conveying worm (23) is driven by motor (14), and filtrate is transported to press cylinder (18) by conveying worm (23), and the filtrate behind press cylinder (18) press dewatering is discharged by slag notch (19).The sewage that sewage that press cylinder (18) is squeezed out in squeezing and hydraulic spray (16) produce filters the back by cylindrical shape filter cloth (17) and is discharged by press cylinder delivery port (20), is flowed into by water inlet (1) after refluxing again.
