Description
Technical field
The present invention relates to a kind of sewage disposal device, particularly the efficient recessed whirlpool air supporting precipitation machine of one.
Background technology
Air supporting and precipitation technology are two kinds of solid-liquid separation techniques conventional in water treatment system, air supporting utilizes the microbubble of the air generation entered in water to be attached on pre-treatment pollutent to form the dirty mixture of gas, due to the imbalance of density between the dirty mixture of gas and liquid, produce buoyancy, contaminant bands is removed to the water surface thus reaches a kind of water technology of purifying waste water; Precipitation is then the most frequently used materializing strategy technology of one that the characteristic utilizing particulate matter to overweight water sinks to that water body carries out solid-liquid separation.In current treatment process, these two kinds of technology occur separately as monomer treatment process substantially, can efficient, easy these two kinds of techniques being combined carry out using rarer.
Air supporting be one fast and efficiently solid-liquid separation technique, in recent years water treatment field use wider, it is to the removal of those frivolous flcos (proportion is close to 1), effect clearly, moreover need lead to the characteristic of oxygen (air) because of its working process, effectively can remove the organism in sewage.Air supporting experienced by for many years as a materializing strategy technology, multi-form development, from traditional loose gas air supporting, air-dissolving air-float, electrofloatation to shallow pool air-floatation in recent years, DAF air supporting, CAF air supporting etc., air-float technology just progressively moves to maturity, and strides forward to features simple structure, land used saving, energy-efficient route.And comparatively popular be in recent years cavitation air flotation system, be utilize bleed equipment to be formed to produce microbubble after negative pressure sucks air to remove impurity, this system device is simple, and Operation and maintenance are very easy to.
Because air supporting is to the selective removal (suspended substance proportion is best close to 1 effect) of suspended substance in water, therefore all there is certain defect in above various air flotation technology, it uses industry, use range, all there is a lot of limitation used to the requirement etc. of water quality, the water quality of water inlet has requirement, the stability of water outlet cannot ensure, cannot carry out using on a large scale, widely, most of occasion appears in technical process as pre-treatment or advanced treatment, independently cannot bear water treatment as core process.

Fig. 2 is structural representation of the present invention;
Fig. 3 is the transmission schematic diagram of step-down gear in the present invention.
Embodiment
See Fig. 2 and Fig. 3, the present invention includes pond body 1, water-in 2, air flotation turbo 3, scraping machine 4, spiral offscum transfer roller 5, return line 6 and water outlet 7; The left side of body 1 inside, described pond is provided with left clapboard 11, and the left field of left clapboard 11 is zone of action 13, and air flotation turbo 3 is arranged in zone of action 13, and the outlet of zone of action 13 is opened in upper end; The right side of body 1 inside, described pond is provided with right clapboard 12, is treatment zone between right clapboard 12 and left clapboard 11, and scraping machine 4 is arranged on the upper end for the treatment of zone and is fixed on pond body 1; Described spiral offscum transfer roller 5 is arranged on the lower right side of scraping machine 4; The bottom of described zone of action 13 is communicated with treatment zone by return line 6; Described treatment zone is divided into Ji Zha district 14 and settling region 15 from top to bottom, and settling region 15 is provided with mud scraper 8; The right side of described right clapboard 12 is the second treatment zone, and the lower end of the second treatment zone communicates with treatment zone, and the second treatment zone is divided into clear water zone 16, sloping plate deposition district 17, sludge hopper 18 from top to bottom; At the bottom of the pond of described sludge hopper 18 in funnel-form and lower than settling region 15, be provided with mud discharging mouth 10 in the bottom of sludge hopper 18; Separating inclined plate 17-1 is provided with in described sloping plate deposition district 17; Described water outlet 7 is arranged on the upper right side of pond body 1, and is in clear water zone 16; The baffle plate of L shape is provided with between described clear water zone 16 and water outlet 7; Described scraping machine 4, spiral offscum transfer roller 5 and mud scraper 8 are driven by same step-down gear 9; The drive shaft of described step-down gear 9 is coaxially provided with the first drive sprocket 9-1, the second drive sprocket 9-2, the 3rd drive sprocket 9-3, scraping machine sprocket wheel 4-1 on first drive sprocket 9-1 and scraping machine 4 is in transmission connection, spiral offscum conveyor sprocket 5-1 on second drive sprocket 9-2 and spiral offscum transfer roller 5 is in transmission connection, and the mud scraper sprocket wheel 8-1 on the 3rd drive sprocket 9-3 and mud scraper 8 is in transmission connection.
The principle of work of this equipment is as follows: mixed solution enters the zone of action 13 that air flotation turbo 3 is housed, the microbubble that pollutent is produced by zone of action 13 and air flotation turbo 3 fully contacts, microbubble is attached on pollutent and forms the dirty mixture of gas, by contaminant bands to the water surface, now the dirty mixture of the gas of a part rises to rapidly Ji Zha district 14, with the rotation of scraping machine 4, scum silica frost is scraped to be sent by spiral offscum transfer roller 5 to spiral slot; The mixture that another part declines because of the effect such as bubbles burst or self gravitation in uphill process enters settling region 15, scraped in sludge hopper 18 in time by bottom mud scraper 8 after precipitation, mixed solution water outlet through air supporting, precipitation process is clean, most pollutent is removed, the pollutent of portion of residual enters sloping plate deposition district 17 immediately, separating inclined plate 17-1 sets up, and " shallow pool principle " is played a role further, and the pollutent in mixed solution is thoroughly removed.
Theory is caught according to sedimentation screen, the precipitate nucleation of backflow contributes to solid-liquid separation process, therefore this equipment is provided with return line 6, because can the region of return line 6 had to form a negative pressuren zone in air flotation turbo 3 high-speed rotation process, this suction function can make settling region 15 mixed solution be back to zone of action 13 at the bottom of pond, returns air supporting section.This process ensures the water backflow of about 40% and still can carry out work without air supporting section when water inlet, the mixed solution of settling region 15 is also supplied to the nucleus being beneficial to materializing strategy into water simultaneously, need not peripheral equipment backflow.
The parts that this equipment comprises air flotation turbo 3, scraping machine 4, spiral offscum transfer roller 5, mud scraper 8 four need motor-driven, each parts all needs to rely on external force transmission to drive and rotates, and need configuration four step-down gear equipment in principle, structure is lengthy and tedious and power consumption is higher.And scraping machine 4, spiral offscum transfer roller 5, mud scraper 8 are designed to a shared step-down gear 9 by this equipment, can consume and save 50%, and maintenance reduce by half, striking off of impurity is provided with synchronism, and structure is simple, easy and simple to handle.
