Abstract
The utility model discloses a cylindrical screen type fine grille, and particularly relates to a fine grille treatment device adaptable to a pre-treatment unit in sewage treatment. The cylindrical screen type fine grille consists of a tank body, a cylindrical screen, a back flushing device, a scraper, a speed reducer and a spindle. The cylindrical screen type fine grille is fed with water externally, fine solid substances can be filtered via the cylindrical screen by means of continuous rotation and attached on the surface thereof, when rotating to a position above the scraper, the fine solid substances are scraped by the scraper which automatically approaches the surface of the cylindrical screen, and sewage after being filtered flows out from a water outlet on the lower portion of the cylindrical screen. The cylindrical screen type fine grille selects a stainless steel filter cylinder with an inverted trapezoid section, strengthens anti-corrosion capacity of a filter screen, prevents the filter screen from being easy to be blocked by aid of a complete self-cleaning system, and is fine in filter effect. Simultaneously, the cylindrical screen type fine grille has the advantages of having low power, compact structure and convenient and simple installation and maintenance management, and being capable of continuously automatically running for a long time.
Description
Technical field
The utility model relates to sewage treatment area, relates in particular to a kind of fine fack device that is used in pretreatment unit in the sewage disposal.
Background technology
Grid is requisite one technology in the sewage disposal preprocessing process, and its effect is that bigger solid matter is removed in interception, and the sump pump in the subsequent technique is shielded, and prevents that process pipeline from stopping up.Existing market is used three kinds of more grids: generally with the rotary type grid of grizzly bar, the rotary type grid of full rake teeth, Barrate type grilling.First kind is mainly used to block bigger foreign material such as branch plastics; Can collect smaller foreign material in the water as size such as cloth cigarette end for second kind; The third generally is used for requiring to collect tiny foreign material, as foam grain, and hair etc.The rotary type grid is used general, low cost, but the subject matter that exists is that the grid filtration effect is relatively poor, and the grid slag after the filtration falls into sewage easily, and the labor cleaning is trouble.The Barrate type grilling filter effect is better, the grid slag can directly transport by worm conveyor, and level of automation is higher, but the subject matter that exists is that cost is more expensive, need bigger installing space, and consider the sewage little widespread use that is fit to northern area of influence of freezing.
Summary of the invention
Based on the existing problem of above-mentioned existing grid, the purpose of the utility model embodiment provides a kind of screen drum formula fine fack, is applicable to the separation of dirt such as less solid suspended particle, fiber, vinasse in trade effluent behind the coarse rack and the sanitary sewage.This equipment preferably resolves the problem that grid falls slag, and it is little energy-conservation to have power, and the compact construction floor space is little, because screen drum formula fine fack is mounted in and is convenient to scarfing cinder, maintenance and management on the channel, but long term continuous automatic operation simultaneously.
The purpose of this utility model is achieved through the following technical solutions.
The utility model embodiment provides a kind of screen drum formula fine fack, and this equipment is export-oriented water inlet screen drum formula fine fack, all adopts the manufacturing of high-quality stainless material, and it mainly is made up of casing, screen drum, back-purge system, scraper plate, step-down gear, main shaft; Wherein, described screen drum adopts the stainless steel cartridge filter of trapezoid cross section, and screen drum is by the step-down gear driven rotary, and the inclination certain angle also is close to the setting of screen drum outer wall.
Casing one side is provided with Movable valve, and cabinet wall is a trapezium-shaped, and end opening broadens gradually to suitable for reading, and lower slightly near water-in one lateral section height.
The main body filter element is a rotation screen drum, and its outer round surface is regular, continuously, arranged water space with spiral form equably, and whole screen drum is the cross section structure of falling the trapezoid, and the slit, the inside is big, and the slit, outside is little.
Screen drum is provided with water outlet under the bottom.
Back-purge system is arranged on screen drum inside, and links to each other with main shaft.
Described casing is provided with inner wall baffle-plate.
The screen drum formula fine fack that the utility model embodiment provides has strengthened the resistance to corrosion of filter screen because screen drum adopts the stainless steel cartridge filter of trapezoid cross section, has guaranteed that filter screen is difficult for being stopped up good filtration effect by dirt.

Embodiment
The utility model embodiment provides a kind of screen drum formula fine fack, is applicable to a kind of fine fack device that is used in pretreatment unit in the sewage disposal.Specifically comprise casing, screen drum, back-purge system, scraper plate, step-down gear, main shaft.At first drive the screen drum rotation by step-down gear, enter the intravital sewage of case after screen drum filters, tiny solid thing and suspended substance are tackled by filter screen in the water, attached to the screen drum surface, in the time of above going to scraper plate, the scraper plate of being pressed close to the screen drum surface automatically strikes off, and drains into worm conveyor and transports, sewage flows into water outlet along screen drum and discharges, thereby reaches the effect of solid-liquid separation.
For ease of understanding, describe below in conjunction with accompanying drawing and specific embodiment.
Embodiment one
As shown in Figure 1 and Figure 2, present embodiment provides a kind of screen drum formula fine fack, is applicable to that the fine fack behind the pretreatment unit coarse rack is handled in the sewage disposal, and this device is made up of casing 1, screen drum 2, back-purge system 3, scraper plate 4, step-down gear 5 and main shaft 6.
At first driving screen drum 2 by step-down gear 5 rotates continuously, sewage is entered by the water-in 11 of casing, after screen drum 2 filters, tiny solid thing and suspended substance are tackled by filter screen in the water, attached to the screen drum surface, in the time of above going to scraper plate 4, automatically the scraper plate 4 of being pressed close to screen drum 2 surfaces strikes off, drain into worm conveyor and transport, sewage is directly discharged by water outlet 33 along screen drum 2, reaches the effect of solid-liquid separation.
The Movable valve 14 of casing plays the effect of be easy to install and maintain inspection and the intravital silt sand of wash-up tray.16 pairs of the inner wall baffle-plates of casing come water mainly to play current stabilization and buffered effect, but ought come the excessive overflow of the water yield to discharge simultaneously, prevent to be flooded between screen drum formula fine fack.Drain 12 plays the effect of emptying.Screen drum 2 adopts the stainless steel cartridge filter of trapezoid cross section, strengthened the resistance to corrosion of filter screen, guaranteed that filter screen is difficult for being stopped up by dirt, good filtration effect, back-purge system 3 inserts back flushing mouth 15 by high-pressure water pipe and outwards carries out back flushing from the screen drum the inside, the back flushing draining is convenient to directly be expelled to water outlet 15, and solid impurity is filtered off.Step-down gear 5 can be adjusted the rotating speed of screen drum 2, the realization optimal operational condition according to coming what of solids in water yield size and the water.
