Abstract
A mould drying room for lost foam casting comprises a drying room (1) which is an enclosed space with a door, and is characterized in that the drying room is provided with door (9) capable of being opened and closed, at least one dehumidifier (6) is arranged in the drying room (9), a drain pipe (5) of the dehumidifier (6) is connected to the outdoor via a pipeline, and at least one heater (2) is arranged in the drying room. The mould drying room is skillful in concept, reasonable in design, simple in structure and convenient in operation, is capable of safely and quickly drying casting moulds in an environment at normal temperature in an environment-friendly manner, simultaneously improves working environments effectively, and has low drying cost which is saved by 20-60% compared with that of the conventional drying method.
Description
Technical field
The utility model relates to a kind of facility of drying processing of casting pattern, and concrete is the apperance drying shed of lost foam casting.
Background technology
Lost foam casting is extensively applied to cast various metal parts.Lost foam casting is the technical process that adopts expandable polystyrene apperance pouring cast part.Foam plastics mould waters fashionable rapid gasification at liquid metal, and molten metal replaces the apperance space, produces one and the duplicate foundry goods of former bubbles model.Lost foam casting is widely used in the foundry goods of various materials such as cast steel, cast iron, cast copper, cast aluminium, various structures.Foundry goods precision height, quality are good, and cost is low; Cast(ing) surface is bright and clean, has reduced cleaning, has saved machining amount.But disappearance model type needs the long time when apperance is dry, be generally 2～4 days, even needs the longer time, just can reach abundant drying.The existing method of medium and small Foundry Works is to set up hothouse, and with coal or fuel gas buring, resistance wire or heat-generating pipe heating or use air-heater, jet chimney, the circumference air dielectric makes the moisture evaporation of apperance, at last hot humid air is discharged hothouse.The shortcoming that these drying means exist is that energy utilization rate is low, and a large amount of hot humid gas enter atmosphere, and energy does not make full use of and wasted.The 2nd, apperance forms disadvantageous thermograde when dry, usually the direction of water translocation is to carry out according to temperature direction from high to low, so the central part in the early stage of drying apperance has always been assembled a large amount of moisture, thick big needs are dry for a long time just can remove the moisture of its heart portion, has prolonged the dry time so greatly.The 3rd, must set up effective reliable temperature control system, otherwise low temperature does not reach dry purpose, high temperature is easy to allow the atrophy of white moding shape.The 4th, the high temperature of inflammable thing foamed plastics and heater has constituted serious disaster hidden-trouble, so hothouse often will be reserved with the enough safe distance in Bai Mo workshop and isolate separately, hothouse must seal heat insulation, increases construction cost, brings inconvenience during use equally.The 5th, operating personnel must operate work under bad environment at hot and humid environment.The 6th, the equipment complexity has strengthened the production maintenance cost.
Summary of the invention
The purpose of this utility model is for solving the problems referred to above that existing disappearance model type exists when apperance is dry, proposes a kind of can be simple under normal temperature environment, conveniently and the apperance drying shed technical scheme of safe lost foam casting.
The technical solution of the utility model: the apperance drying shed of lost foam casting, drying shed is an enclosure space, drying shed is provided with door, it is characterized in that, drying shed is provided with closable door, be provided with at least 1 dehumidifier in the drying shed, the drainpipe of dehumidifier is connected to outdoor by pipeline, is provided with at least 1 heater in the drying shed.
The single or double acting door that described Men Weike closes automatically.Described drying shed internal heater is at least a in heat lamp, resistive heater, quartz heating tube, air-heater, warmer and the electric furnace.Be provided with temperature ﹠ relative humidity indicator in the described drying shed.
The process of apperance drying is the transmission migration and the evaporation of moisture in the apperance.For making the apperance drying, must guarantee that apperance surface moisture vapor partial pressure is higher than the moisture vapor dividing potential drop in the space outerpace, just can make apperance surface moisture vaporization and spill in the space outerpace medium, thereby in apperance surface and the inner difference that water content occurs, the apperance internal moisture is constantly vaporized to surface transmission migration and on the surface, and then the water content of apperance inside is constantly reduced, progressively finish the volume drying of apperance.The utility model is to be provided with dehumidifier in drying shed, the dehumidifying continuous fast Absorption of function is also got rid of airborne moisture in the drying shed, apperance surface moisture vapor partial pressure is higher than the moisture vapor dividing potential drop in the space outerpace, make apperance surface and inner occur bigger moisture poor, the moisture on apperance surface enters air after vaporizing naturally, is absorbed by dehumidifier; Constantly to apperance surface migration and vaporization, the water content of apperance inside progressively reduces the water content of apperance inside, finishes the drying of apperance simultaneously.For accelerating the vaporization of apperance surface moisture, the utility model is provided with heat lamp in drying shed.For preventing that the moisture that dehumidifier absorbs is vaporized in the air that enters once more in the drying shed, the utility model leads to the discharge outlet of dehumidifier drainpipe outdoor.Be the convenient temperature and humidity of grasping in the drying shed, the utility model is provided with thermometer and hygrometer in drying shed.
The utility model is skillfully constructed, and is reasonable in design, simple in structure, and handled easily can effectively improve working environment simultaneously at the dry apace cast pattern of safety and environmental protection under the normal temperature environment.Drying cost is low, than the saving 20～60% of traditional drying method.
Description of drawings
Fig. 1 is the utility model structural representation.
Among the figure, (1) is that drying shed, (2) are that heater, (3) are that thermometer and hygrometer, (4) are that roof, (5) are that drainpipe, (6) are that dehumidifier, (7) are that apperance, (8) are that bracing frame, (9) are doors.
The specific embodiment
According to foundry goods annual production, foundry goods substance and foundry goods complexity design drying shed volume; According to foundry goods annual production, drying shed humidity, foundry goods substance and foundry goods complexity design dehumidifier power; According to foundry goods annual production, drying shed humidity, foundry goods substance and foundry goods complexity design heater power.
Build 150 cubic metres of closed drying sheds with cement block, also can build the drying shed (1) of brick mix structure, on drying shed, be provided with closable door, be provided with a 2.82KW in the drying shed, model is the industrial dehumidifier (6) of CFZ-7S, and the discharge outlet of dehumidifier drainpipe (5) is led to outdoor.The roof of drying shed (4) is provided with 4 250W heat lamps (2), and heat lamp can doublely be made illuminating lamp.In drying shed, be provided with temperature ﹠ relative humidity indicator (3).Heater also can adopt in resistive heater, quartz heating tube, air-heater, warmer and the electric furnace at least a.Warmer can be oily spit of fland or quartz heating tube formula.In drying shed, be provided with temperature ﹠ relative humidity indicator (3).
