Description
Technical Field
The invention belongs to the technical field of oil-containing sewage treatment devices in oil fields, and particularly relates to a slag scraper used in water treatment air floatation separation equipment.
Background
In the treatment of oilfield produced water, air floatation equipment is often used for separating and removing free oil and suspended particles which cannot be removed in the sedimentation process in sewage. The principle is that gas-dissolving water dissolved in air is mixed into water to be treated through a releaser, micro bubbles (10-30 mu m) are released uniformly by sudden pressure reduction, dense micro bubbles collide and adsorb micro suspended particles in the water in the rising process, and suspended matters wrapping the bubbles continuously float upwards and are continuously accumulated on the liquid surface, so that the separation of the suspended matters is realized. The slag scraper is used for scraping the scum of the foam-shaped solid floating on the liquid surface to the discharge end so as to collect and discharge the scum.
The common slag scraper is generally composed of a scraper, a chain, a driving shaft, a driven shaft, a bearing support, a motor and a speed reducer. The driving shaft and the driven shaft are respectively fixed at two opposite ends of the upper part of the water treatment container through a bearing and a bearing support; two ends of the two shafts are respectively provided with a chain wheel, and the two closed-loop chains are respectively matched with the two pairs of chain wheels; a plurality of scraping plates are vertically and uniformly distributed on a closed ring formed by the whole chain along the direction of the chain; the motor drives the transmission shaft and the chain wheel through the speed reducer to drive the two chains to synchronously move, the scraper moves to the other end from one end of the bottom of the chain ring along with the chains, then bypasses the chain wheel at the opposite end, returns to the starting end from the upper part, and sequentially reciprocates; the scraper is arranged below the chain ring from one end to the other end in a stroke, one part of the scraper is positioned below the liquid level and is used for scraping scum on the liquid level, and when the scum scraped by the scraper is close to the tail end scum outlet, the accumulated scum can be pushed into the scum outlet in a centralized way through an upward slope.
The scraper mounting rack of the existing slag scraper is fixedly connected with a chain at a right angle; the scraper is fixed on the scraper mounting frame and made of flexible materials, so that the scraper can pass through the slag discharge hole slope.
The existing slag scraper still has the following problems when in use:
① due to the limitation of installation accuracy, abrasion or deformation, the two side chain wheels may have rotation phase difference, the fixed rigid connection between the chain and the scraper installation seat has stress concentration, and is often easy to fatigue fracture, the scraper falls off, when only one end of the scraper is separated from the chain, the other end of the scraper can cause another chain to be tired, so that the scraper is out of the groove or damaged, and the production is stopped and maintained immediately.
②, in order to prevent the flexible scraper from deforming under stress during scraping, the scraper is usually thickened, which results in thicker and heavier scraper, and the weight is increased, and when the chain is very long and a nylon chain is used, the chain is also very heavy, and the upper and lower sections of the chain need chain brackets to bear the weight of the chain and the scraper;
③, the liquid level to be treated often has a floating movement of about 100mm up and down, and the scraper must be made wider to ensure that the scraper is always inserted below the liquid level.
④ to pass through the slag discharge hole slope, the prior scraper must be made of a part of flexible material which is easy to deform.
⑤, the chain is very long, if the lower section of the chain is not provided with a bracket and is influenced by gravity, the lower section of the chain is difficult to avoid into an arc shape, the depths of the groups of the scrapers of the lower section of the chain which are vertically inserted below the liquid level are different, the depth of the scrapers at the arc top of the lower section of the chain which are inserted is too deep, so that the resistance is large, the scrapers at the arc edge of the lower section of the chain which are inserted are too shallow or not inserted below the liquid level, so that the scraping effect is not in place or.

Firstly, one end of the scraper body can float up and down along with the liquid level under the driving of the buoyancy of the buoy, so that a part of the scraper body is always inserted below the liquid level, the scraper does not need to be wide, and the whole weight of the scraper is reduced; secondly, the depth of all the scraper assemblies inserted below the liquid level at the lower section of the chain is ensured to be the same, compared with the prior art, the problem that the scraper assemblies at the middle part of the lower section of the chain are inserted too deeply and the scraper assemblies at the two sides are inserted too shallowly is avoided, the problem of uneven scraping is solved, and the scraping effect is well improved; thirdly, the slope of the slag discharging port is not required to pass through by means of deformation of the scraper component; fourthly, due to the buoyancy of the floating barrel, the load of the dead weight of the scraper body on the chain is reduced, and the chain support of the lower section of the chain is omitted.
2. The scraper blade body is formed by bending rigid materials integrally, a folded plate structure rigid body is formed, and the scraper blade body is very small in deformation when stressed, so that the concentrated stress of a connecting point of the scraper blade body and a chain is reduced.
3. Compared with the prior art that the chain and the scraper mounting seat are fixedly and rigidly connected, the chain and the scraper assembly are hinged, so that the fracture of the joint of the scraper and the chain caused by stress concentration is avoided.
4. Because the two ends of the scraper body are respectively connected with the two chains, the two chains are difficult to complete, if the chains and the scraper are in hard connection, the generated torque can generate concentrated stress at the connection part, and the connection point structure and the adjacent related parts of the chains are easy to damage; the scraper body is connected with the chain through two mutually vertical shafts, has two shafts and four degrees of freedom, can not generate torque in the operation process, and prolongs the service life of the whole device.
