Description
Technical Field
The invention relates to the technical field of hot galvanizing of steel pipes, in particular to a cooling and conveying device of hot galvanized steel pipes.
Background
The Hot galvanizing (Hot dip galhvaining) technology is the most basic, most extensive and oldest method in the corrosion prevention methods of steel in the world at present, and compared with other metal corrosion prevention methods, the Hot galvanizing technology has the advantages of electrochemical protection of a coating, compactness of the coating, durability of the coating, maintenance-free property of the coating, bonding force of the coating and a substrate, economy of the coating and the like, which are incomparable with other technologies, and the Hot galvanizing of the steel tube is quite widely applied in national economic construction.
In the existing steel tube hot galvanizing production, the steel tube hot galvanizing process comprises the following steps: the method comprises the steps of steel pipe pickling and rust removal, 2-channel water rinsing, plating assisting treatment, drying, hot galvanizing, external blowing and wiping of residual zinc, internal blowing and wiping of residual zinc, air cooling, water cooling, rust prevention treatment, inspection and packaging.
After the steel tube is cooled by external blowing and wiping residual zinc, internal blowing and wiping residual zinc and air, the surface temperature of the galvanized steel tube is still more than 200 ℃, if the galvanized hot steel tube is not cooled down rapidly, the pure zinc layer on the surface of the steel tube and oxygen in the air are oxidized very rapidly, so that the galvanized layer on the surface of the steel tube becomes dark, and meanwhile, the surface of the steel tube can be provided with a moire phenomenon, and the corrosion resistance of the steel tube can be seriously affected by the moire phenomenon. Therefore, in the hot dip galvanizing process of the steel pipe, there is a need to have a "water cooling" process after the "air cooling" of the hot dip galvanized steel pipe.
In the existing hot dip galvanizing production process, after being cooled by air, the hot dip galvanized steel pipe is directly dropped into a cooling water tank through a transverse moving stepping device, and the hot dip galvanized steel pipe with high temperature is cooled. And then the cooled hot dip galvanized steel pipe is taken out of the cooling water tank through a chain with a toothed plate. The following description is shown in figure 1.
Although chain transmission has the advantages of large bearing capacity and accurate transmission ratio, the adoption of a chain to convey the cooled hot dip galvanized steel pipe to a hot dip galvanized steel pipe placing frame has the following outstanding problems:
(1) In the process of conveying the hot dip galvanized steel pipe by adopting the chain, the surface of the chain and the surface of the hot dip galvanized steel pipe can displace, friction is generated, and the surface smoothness is affected.
(2) The hot dip galvanized steel pipe is conveyed to the water control table through two groups of chains, and in the process, the running cannot be completely synchronous sometimes due to the fact that the speed of the chains is not constant, the phenomenon of 'holding the pipe' is extremely easy to occur, and the phenomenon of bending the pipe caused by the phenomenon of 'holding the pipe' also occurs sometimes. Waste products are caused by bending of the hot dip galvanized steel pipe.
(3) In the existing production, the water cooling process method for the hot dip galvanized steel pipe comprises the following steps: the cooling water tank is placed below the transverse moving mechanism, the hot dip galvanized steel pipe just can fall down, the hot dip galvanized steel pipe directly falls into the water of the cooling water tank from a high position, noise is large in the production process, hot water at the temperature of about 80 ℃ is splashed to the periphery of the cooling water tank, the working environment is affected, and potential hazards to a certain extent are brought to personnel safety of staff.
(4) The chain is soaked in water for a long time, lubrication is insufficient, corrosion of parts is accelerated, parts are maintained and replaced frequently, and operation cost is increased. Therefore, in the hot galvanizing production of the steel tube, the mode of conveying the hot galvanized steel tube through a chain mechanism after cooling the hot galvanized steel tube is a technical problem to be solved urgently by the hot galvanizing enterprises of the current steel tube.

Preferably, the steel pipe conveying chains are arranged at two ends of the chain transmission shaft in parallel and correspondingly.
Preferably, the poking wheel is provided with poking grooves uniformly distributed along the circumference, two sides of the poking grooves uniformly distributed along the circumference are in an inclined shape, the bottom of each poking groove is an arc surface, the arc radius R of each arc is 50-150 mm, the preferred R is 120mm, the poking grooves on the poking wheel are 6-16, the included angle beta between the short sides of the poking grooves and the long sides of the poking grooves is 30-60 degrees, and the included angle alpha between the long sides of the poking grooves and the tangent line of each arc of the poking wheel is 15-35 degrees.

Technical effects of the invention
According to the cooling and conveying device for the hot dip galvanized steel pipe, the hot dip galvanized steel pipe is conveyed in a straight manner by the conveying chain, and is conveyed in the circular arc wheel groove of the wheel 31 and 32, and the wheel 31 and 32 are arranged on the wheel transmission shaft, so that the wheel 31 and 32 synchronously rotate, and two ends of the hot dip galvanized steel pipe 132 are positioned on the same horizontal line, and therefore the problem of 'pipe holding' in the process of conveying the hot dip galvanized steel pipe to leave cooling water in cooling water through the chain in the traditional hot dip galvanized steel pipe is avoided, and the problem of 'pipe bending' caused by 'pipe holding' is avoided.
The invention overcomes the defect that when the traditional steel pipe is cooled, the hot dip galvanized steel pipe directly falls into the cooling water of the cooling water tank from the cooling rack, and because the hot dip galvanized steel pipe matrix at the moment has high temperature of more than 200 ℃, after the hot dip galvanized steel pipe enters the cooling water, the cooling water in the hot dip galvanized steel pipe is quickly vaporized and boiled, and the vaporized high-temperature water vapor in the galvanized steel pipe is flushed out of the cooling water tank, so that the scalding accident of workers is easy to occur.
In the water cooling process, the invention avoids the noise problem formed by water vapor and water in the steel pipe by spraying water outwards after the steel pipe is buckled after the hot dip galvanized steel pipe boils and vaporizes.
According to the invention, red copper strips with the thickness of H being more than or equal to 8 and less than or equal to 10mm are embedded on the inner surfaces of the poking grooves of poking wheels 31 and 32 and the inner surfaces of steel pipe brackets 61 and 62, so that the problem of surface friction of hot dip galvanized steel pipes and direct collision of the steel pipes are reduced, and the defect of local scratches on the surfaces is overcome.
