Detailed description of the invention
A kind of casting cooling barrel, comprises staving 1, base 12, drive unit and transmission device.As shown in Figure 1 and Figure 2, base 12 be provided with some to for support staving 1 and promote staving 1 rotate support roller 11, staving 1 is provided with charging aperture 6, discharging opening 16 and dedusting passage 17.The top of dedusting passage 17 is provided with dust excluding hood 18 and cleaner.
Air cooling equipment and interior water cooling plant is provided with in described staving 1.Air cooling equipment comprises some layers of forced air cooled tube 7, and wherein, the forced air cooled tube of lower floor is corresponding with the gap of adjacent two forced air cooled tubes on upper strata; The two ends of forced air cooled tube 7 pass staving 1, and front end is provided with air inlet 8, and end is communicated with dedusting passage 17; Interior water cooling plant comprises some layers of water cooling tube 10, and wherein, the water cooling tube of lower floor is corresponding with the gap of adjacent two water cooling tubes on upper strata.This structure can allow the sand kicked up in drum in dropping process, has more large-area contact with forced air cooled tube 7, water cooling tube 10, to carry out heat exchange better, improves cooling effectiveness.
The two ends of water cooling tube 10 pass staving 1, and front end is provided with water inlet 9, and end is provided with delivery port 15.Described delivery port 15 is connected by circulating water pipe 14 with water inlet 9, and circulating water pipe 14 is provided with cooling device 13.The water of discharging from delivery port 15 is through the hot water after heat exchange, by after the cooling of cooling device 13, is circulated to water inlet 9, again enters water cooling tube 10 and reuse, so, greatly saved water resource.
The top of described staving 1 is provided with outer water cooling plant, comprises outer cold water pipe 3 and is evenly arranged on several water spouts 4 bottom outer cold water pipe 3.Outer cold water pipe 3 is communicated with described water inlet 9.In staving 1 rotation process, water spout 4 pairs of staving spray cold water, like this, the sand in staving 1, can be further cooled.
The inwall of described staving 1 is evenly provided with the scraper plate 5 of several axis.Be provided with several kicker baffles 2 in described staving 1, kicker baffle 2 comprises the division board of guide plate that top turns forward and lower vertical, and division board is vertically fixedly connected on described forced air cooled tube 7 and water cooling tube 10.
Operation principle: high temperature sand enters staving 1 from charging aperture 6, under the effect of kicker baffle 2, first sand enter ground floor cooling chamber, with forced air cooled tube 7, water cooling tube 10 bump contact in sand dropping process, after there is heat exchange, drops on bottom staving 1.Staving 1 rotates under the promotion of support roller 11, along with the rotation of staving 1, under the effect of scraper plate 5, sand is kicked up, bucket intracorporeal space parabolically shape fall with air heat exchange after, under the effect of kicker baffle 2, sand enters second layer cooling chamber along guide plate, with forced air cooled tube 7, water cooling tube 10 bump contact, again there is heat exchange.Like this, be further cooled in the cooling chamber of sand successively below, meanwhile, water spout 4 pairs of stavings 1 of the outer cold water pipe 3 above staving 1 spray cold water, also cool sand further.By the time sand is from last one deck cooling chamber, and when discharging opening 16 is discharged, temperature reduces greatly.
In addition, logical hot blast in forced air cooled tube 7, logical hot water in water cooling tube 10 and outer cold water pipe 3, the present invention just can make drying plant and use, and is dried by the material of humidity.That is, the present invention has both cooling and drying function efficiently, and a tractor serves several purposes, saves production cost greatly.
