Description
Technical Field
The utility model relates to a sewage treatment field especially relates to an oil skimming and slag scraping vehicle of oil harrow and slag harrow linkage.
Background
In the process that sewage is settled in the advection sedimentation tank, suspended matters in the sewage float and sink under the action of gravity and medicines because of different density differences with water. Scum or oil sludge on the water surface and bottom mud settled at the bottom of the pool are generally removed by a slag scraping device.
For sewage treatment units with lower sediment density and small width of an advection pool, some enterprises select a chain rotary type slag scraping device; for sewage treatment units with high sediment density and large width of an advection pool, a truss vehicle type slag scraping device is selected and generally called as a slag scraping and mud scraping vehicle or an oil skimming and slag scraping vehicle.
When the steel industry is used for treating hot-rolled turbid circulating water, the turbid circulating water passes through a trench and a cyclone well and then stays in an advection pool for a long time to remove oil, dust, fine iron scales and the like in the turbid circulating water. Oil, dust and the like float up to the water surface to form an oil layer, and the fine iron scale forms iron mud at the bottom of the advection pool. Because the iron mud has high density and high requirement on the strength of slag scraping equipment, when a slag car travels from a water outlet end to a water inlet end, a slag rake falls to the bottom of a pool to scrape slag (iron mud) in the traditional truss type slag car; when the slag car moves from the water inlet end to the water outlet end, the slag rake is lifted to the water surface for oil scraping.
Enterprises have great fluctuation of water quality in the advection pool due to different production working conditions, and the water quality of some enterprises is very poor for a long time, so that the advection pool is subjected to online process transformation, some water treatment devices are added in the pool to form an obstacle in water, so that the slag rake is interfered with the obstacle in the falling and rising processes, and can only be lifted and lowered in a small range at the bottom of the pool, and the slag rake loses the function of serving as an oil rake. The slag scraping vehicle needs to be modified, and the requirement that the slag vehicle has oil scraping and slag scraping functions at the same time is met.
For example, patent document CN200820118057.1 discloses a multifunctional oil and slag scraping machine used in a water treatment system. The oil scraper is mainly composed of a single-rake oil scraping and residue scraping machine and an oil scraper lifting device, an oil scraper, a single-rake oil scraping and residue scraping machine and linkage oil scraper adjusting mechanism, a residual oil scraper linkage hinge shaft and other mechanisms, and has the advantages of various oil removing forms, high efficiency of scraping residue and oil, strong environment adaptability, difficult rail falling of a vehicle body, high automation degree and the like. However, when the obstacle exists in the water, the lifting of the slag rake can interfere with the obstacle in the water, the lifting height is limited, and when the production fluctuation water surface descends, the oil rake can not contact the water surface due to linkage.
Patent CN201520783571.7 discloses a device for removing oil and sludge simultaneously, which utilizes a bracket and a chain to form a loop, a mud scraper is mounted on the outer surface of the bracket, and an oil scraper is mounted on the inner surface of the bracket to drive the oil scraper. However, iron mud density of iron and steel enterprises is high, the length and the width span of the advection pool are large, the length of some advection pools is about 40-65m, the width is 8-12m, and the overlarge size makes the equipment difficult to meet the requirements on strength.
Patents CN201520783809.6, CN201711300482.2, CN201721702913.3 all adopt chain, bracket, scraper structures basically, although the functions of scraping oil and slag simultaneously exist, for the iron mud in the horizontal flow tank in the steel industry, the commonness of insufficient strength and insufficient functions exists.
The above patents are basically slag scraping vehicles used in municipal sewage and oilfield sewage treatment processes, are not specially designed for iron-containing mud sewage in the steel industry, and have defects in functions and strength. In some advection pools, the operation of the slag car is influenced by adding a processing unit, and appropriate modification is needed to meet the production requirements.
