Description
Technical Field
The invention belongs to the technical field of metallurgical equipment, and particularly relates to an online quenching water temperature control and circulation system for an aluminum profile, which is suitable for online quenching of aluminum profile extrusion.
Background
The control and circulation of the quenching water temperature are the crucial links in the online quenching of the aluminum profile, the control of the quenching water temperature directly determines the quenching effect, if the water temperature is improperly controlled, a series of problems of incomplete quenching, uneven mechanical properties of materials, insufficient strength and the like can occur, and the qualification rate and the production efficiency of extruded products are seriously influenced. Because extrusion production is adopted, once the problem occurs, the problem is a large-batch problem, and huge economic loss and resource waste are brought to production enterprises, so that the control and circulation of the quenching water temperature are particularly important in the whole quenching process. At present, two methods are used in the industry, one method is to increase the length and time of a circulation path of hot water after quenching through the design of a pipeline and the special design of a water tank, and achieve the effect of cooling circulation through natural cooling. The method adopts fluid natural flow circulation cooling, so the circulation effect is better, the failure rate is basically avoided, but the cooling effect is poor and uncontrollable, the mass production quality problem is caused once the water temperature exceeds the standard, the civil engineering cost is high, a larger water pool and more cooling water are needed to increase the circulation time, and the natural cooling effect is ensured. Another method is to add a cooling circulation device to cool the water in the hot water pool through the cooling circulation device, which is also the method commonly adopted at present. The method has good cooling effect, but has high failure rate, needs a cooling circulation system to work all the time, has large resource waste and large control difficulty, and increases the production cost; the water absorption amount of the cooling circulation is matched with the quenching working water amount, and once the cooling circulation device stops or breaks down, the cold water tank does not return water, the quenching working pump is damaged to cause the whole quenching system to work, even the circulating water of the whole quenching system can not be discharged in serious conditions, the problem of waterlogging of the whole production workshop is caused, the reliability of equipment is reduced, and the operation risk is increased.

Detailed Description
The present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1-2, an online quenching water temperature control and circulation system for aluminum profiles comprises a hot water tank 4 connected with a quenching working section 2 through a water return pipe 3, a circulating channel 12 is arranged between the hot water tank 4 and a cold water tank 11, the bottom of the hot water tank 4 is connected with a water suction pipe 5 of a circulating pump 6, and the outlet of the circulating pump 6 is sequentially connected with a filter 7, a cooler 8 and a water outlet pipe 10; the water outlet pipe 10 is connected with the cold water tank 11 and is higher than the liquid level of the cold water tank 11; a temperature sensor 9 is arranged in the cold water tank 11, the cold water tank 11 is also connected with a quenching working pump 13 and used for conveying quenching water to the quenching working section 2 for on-line quenching of the extruded section 1; set up circulating passageway 12 between hot water pond 4 and the cold water pond 11, its effect is: the return water after quenching, after 4 natural cooling in hot water pond, can return to cold water pond 11 through passageway 12, if the quenching water consumption is little, need not to open external cooling cycle device, this passageway setting has increased natural cooling time and cycle period in the upper portion in pond simultaneously to better cooling effect has been played.
The central height of the channel 12 is 0.7-0.8 times of the total height of the pool.
The height of the suction pipe 5 is 0.2 times of the total height of the water pool.
The working principle of the invention is as follows: when on-line quenching is carried out, the on-line extruded aluminum profile 1 is in the quenching working section 2, the quenching working pump 13 conveys water in the cold water tank 11 to the quenching working section 2 to quench the extruded aluminum profile 1, and the quenched hot water flows into the hot water tank 4 through the return water pipe 3 of the quenching working section; the water in the hot water tank 4 is conveyed to the cold water tank 11 in two circulation modes: one circulation mode is that the water flows into a cold water pool 11 from a channel 12 between the hot water pool and the cold water pool after being naturally cooled by the hot water pool, and the other circulation mode is that the water is transported to the cold water pool 11 by a circulating pump 6 through a water suction pipe 5 of the circulating pump through a filter 7 and a cooler 8, and then the water of the cold water 11 is transported to a quenching working section 2 through a quenching working pump 13 to quench the extruded aluminum profile 1. A temperature sensor 9 is arranged on the cold water pool 11, and a quenching water temperature control and circulation method can be selected according to the temperature of the cold water pool 11.
Because the whole quenching water system is circulated, according to the characteristic of the aluminum profile quenching process, when the water temperature of the cold water tank 11 is lower than 45 ℃, the circulating water pump 6 does not need to be started, hot water in the hot water tank 4 can flow into the cold water tank 11 through the channel 12 after being naturally cooled, the central height of the channel 12 is 0.7-0.8 times of the total height of the water tank, the circulation time is conveniently increased, and a better natural cooling effect is obtained; this cycle saves resources, is simple and fault-free.
When the water temperature of the cold water pool 11 is more than or equal to 45 ℃, the first circulation can not meet the cooling requirement, the circulating water pump 6 is started, the hot water in the hot water pool 4 passes through the water suction pipe 5 of the circulating pump 6, the circulating pump 6 transports the water to the cold water pool 11 through the filter 7 and the cooler 8, the cooling capacity of the cooler 8 is enough to ensure that the water temperature returning to the cold water pool 11 is lower than 45 ℃, and the water can flow into the cold water pool 11 through the channel 12 of the hot water pool 4, so that even if the circulation at the circulating pump 6 fails or stops, the whole quenching equipment can not stop or the workshop waterlogging can not be caused.
The water in the cold water pool 11 is conveyed to the quenching working section 2 through the working pump 13 and then returns to the hot water pool 4, self-circulation is formed, and meanwhile, the effect of first circulation can be achieved.
