Abstract
A drum-type sand cooling machine belongs to the technical field of casting equipment. One end of a rotatable horizontal-type drum is provided with a hot sand inlet and a hot gas outlet, the other end thereof is provided with a cold sand outlet and a cold and moist air inlet; the cold and moist air inlet is butted with a cold and moist air outlet with a blower micro-atomization device by a rotary bracket; a plurality of spoon-shaped sand-winnowing plates which are evenly distributed in an interlacing way are fastened inside the drum along the axis direction of a drum body; the drum body is linked with a motor in a deceleration and transmission way; and a spraying device is arranged over the drum. The drum body can be supported on two groups of supporting wheels below by two ring-shaped rolling rings on the drum body, a driven tooth ring is sheathed and fastened on the drum body between the two ring-shaped rolling rings, and a driving gear driven by the motor deceleration is meshed with the driven tooth ring. The drum-type sand cooling machine has the advantages of: high sand cooling efficiency, small sand smashing rate, function of sand-clearing, simple maintenance, low energy consumption, and being especially suitable for need of production lines with fast tempo.
Description
Technical field
The utility model belongs to the Casting Equipment technical field, is specifically related to the but equipment of sand cooling on a kind of foundry production line.
Background technology
Sand cooling on the existing foundry production line but equipment mainly is traditional old-fashioned drum-type sand cooling machine, or the cooling ebullated bed of highly energy-consuming.Old-fashioned drum-type sand cooling machine sand percentage of damage height, water capacity is big, mainly is applicable to the production of wet sand casting and resin sand casting; Though and cooling ebullated bed power consumption is very high and investment is big, cooling effect is unsatisfactory, also is not suitable for the needs of fast pace production line, particularly the needs of moulding on lost foam casting and the V method foundry production line.
The utility model content
The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of not only energy consumption low, and the sand percentage of damage is little, easy to repair, the drum-type sand cooling machine that sand cooling efficient is high.
Structure of the present utility model: an end of rotating horizontal drum establishes hot sand import and heat outlet, the other end are established cold sand outlet and cold humid air import, cold humid air import is docked by rotary bracket with the cold humid air outlet of band blower fan micro-atomizing device, be fastened with staggered a plurality of spoonfuls of uniform shapes along the tubular axis direction in the cylinder and raise the sand plate, roller tube and motor deceleration transmission connect, and spray equipment is established in the cylinder top.Said band blower fan micro-atomizing device is a prior art, and the commercially available prod is arranged.One of concrete structure that roller tube and motor deceleration transmission connect, can be: by two annular rolling rings on the roller tube with barrel support on two groups of support rollers of below, one passive tooth snare is established and is anchored on two cylindrical shells between the annular rolling ring, and the driving gear and the passive gear ring that are driven by motor deceleration mesh.According to the amount of cooling water of sand, the cylindrical shell length of cylinder can be 6～30 meters, and diameter can be 1.5～3.0 meters.Passive gear ring preferably adopts the pin tooth, and its benefit is that cost is low, and single-piece work is easy, is fit to the working environment of high temperature with high dust, and the pin tooth is replaceable.
The course of work of the present utility model: the uniform rotation of motor drives cylinder, high temperature sand enters cylinder continuously from the hot sand import of cylinder one end, raises at the spoon shape to seethe under the effect of sand plate and advances.The band particle diameter be 5～10 microns little mists cold humid air, from the cylinder other end through cold humid air import blasted cylinder, and reverse Continuous Flow cross and seethe the high temperature sand of kicking up, the two carries out very sufficient heat exchange.Take away a large amount of heat after little mist vaporization in the cold humid air, but it is too many and broken that sand is made moist.The fine solid particle that heat-exchanged air and little mist vaporization moisture are carrying in the sand is sent by the cylinder heat outlet, is sucked in the water dust scrubber by the air-introduced machine of supporting installation.The lower procedure that sand is handled line is discharged, entered to the sand that turns cold after sufficient heat exchange by cold sand outlet.The spray equipment chilling roll outer wall of spraying water continuously of top further strengthens the cold sand effect of equipment.Sand cooling of the present utility model but efficient is more than three times of old-fashioned conventional rollers formula sand cooling machine, removes the function that fine powder purifies sand in addition in addition.
Advantage of the present utility model: sand cooling efficient height, the sand percentage of damage is little, has clean sand function, and easy to repair, energy consumption is low, is particularly suitable for the needs of fast pace production line.
Description of drawings
Fig. 1 is the main TV structure schematic diagram of embodiment.
Fig. 2 is the A-A cross-sectional view (wherein raising the sand plate represents with stereochemical structure) of Fig. 1.
The specific embodiment
See the embodiment shown in Fig. 1 and 2: an end of horizontal drum 4 is established the hot sand import 8 of inclination, and heat outlet 7.The other end of cylinder 4 is established cold sand outlet 2 and cold humid air import 13.Cold humid air import 13 is docked by rotary bracket with the cold humid air outlet of band blower fan micro-atomizing device 1.Band blower fan micro-atomizing device 1 is the commercially available prod.Be welded with staggered a plurality of spoonfuls of uniform shapes along the tubular axis direction in the cylinder 4 and raise sand plate 5.The cylindrical shell of cylinder 4 and motor 14 connect through reduction box 9 transmissions.Spray equipment 6 is established in cylinder 4 tops.Establish two annular rolling rings 3 on the cylindrical shell of cylinder 4, by rolling ring 3 with barrel support on two groups of support rollers 10.Passive gear ring 12 sheathed being anchored on two cylindrical shells between the rolling ring 3.The driving gear 11 that is driven by motor 14 decelerations meshes with passive gear ring 12.Passive gear ring 12 adopts the pin tooth.
Above embodiment is only in order to be further described the utility model, and scope of the present utility model is not subjected to the limitation of illustrated embodiment.
