Abstract
The invention discloses a circulating hot air sand core surface drying furnace. The circulating hot air sand core surface drying furnace comprises a furnace body and a heater. The heater is located in a heater chamber. An air feeding port and an air return port are formed in the bottom of the heater chamber. A hot air circulating system is located below the top of the furnace body, the air feeding port and the air return port. The hot air circulating system comprises a circulating fan and an air feeding pipe located at the top of the furnace body. An air outlet of the circulating fan is communicated with the air feeding port. An air blowing nozzle is arranged at the bottom of the air feeding pipe. Waste discharging devices are symmetrically arranged at the two ends of the upper portion of the air feeding pipe. Air return pipes are symmetrically arranged on the two sides of the air feeding pipe and communicated with the heater chamber through the air return port in the bottom of the heater chamber. By the adoption of the circulating hot air sand core surface drying furnace, a workpiece is dried in a forced hot air circulating manner, and the structure that air is fed through the top and returned through the two sides is adopted in hot air circulation, so that the workpiece is heated evenly, the temperature is proper, and the drying speed is increased; and the waste discharging devices are arranged in the furnace body so that moisture in the furnace body can be removed in time and the drying speed can be further increased.
Description
Technical field
The present invention relates to sand core drying equipment technical field, particularly relate to circulating air sand core watch dried furnace.
Background technology
Resin bonded sand mould (core) water content is lower, be generally 0.2-0.3%, its water content does not affect casting quality, but moisture depth of penetration is generally 6-8mm after applying coatings, in order to meet manufacturing technique requirent, the drying mode that prior art adopts has: 1, direct baking formula, is placed in baking box by core and dries, skin drying and core body inside cannot be dried, and core amount of stored heat is very large; 2, directly core put into stir blower fan agitating heating baking box in toast, although utilize wind brush and heating energy makes core surface dry as early as possible, irregular due to sand mold itself, be difficult to core surface is heated evenly, therefore there is dead angle, be difficult to the core quality obtained.
Summary of the invention
In order to solve the problem existing for background technology, the object of this invention is to provide a kind of structure simple, be heated evenly, circulating air sand core watch dried furnace that drying efficiency is high.
To achieve these goals, technical scheme of the present invention is achieved in that circulating air sand core watch dried furnace, it comprises body of heater 1, heater 2, described heater 2 is positioned at heater chamber body 8, air outlet 6 and return air inlet 7 is provided with bottom described heater chamber body 8, be positioned at described body of heater 1 top, the below of described air outlet 6 and return air inlet 7 is provided with hot air circulating system 5, described hot air circulating system 5 comprises circulating fan 501 and is positioned at the ajutage 502 at described body of heater 1 top, the air outlet of described circulating fan 501 is communicated with described air outlet 6, blowing mouth 504 is provided with bottom described ajutage 502, two ends above described ajutage 502 are symmetrical arranged waste discharge apparatus 3, the bilateral symmetry of described ajutage 502 is provided with backwind tube 503, described backwind tube 503 is communicated with described heater chamber body 8 by the described return air inlet 7 be located at bottom described heater chamber body 8.
Further, described waste discharge apparatus 3 mainly comprises blast pipe 301.
Further, described air curtain apparatus 4 symmetry is installed on the two ends of described body of heater 1 shell.
Further, described air curtain apparatus 4 mainly comprises blower fan 401.
The present invention has following beneficial effect: the present invention adopts forced hot air circulation mode to dry workpiece, and hot air circulation adopts the structure of top supplying air both sides return air, and this structure makes workpiece be heated evenly, and proper temperature improves rate of drying; Be provided with waste discharge apparatus in body of heater and can remove moisture in body of heater in time, accelerate rate of drying further.
