Abstract
The utility model provides a fired mold precision casting shell drying chamber, wall and the closed door of setting on one of them face wall wall that it meets perpendicularly for two liang and form square frame including the four sides, the offside of the closed door of drying chamber sets up constant temperature and humidity machine, sets up the multirow fan side by side relatively with sealing the adjacent both sides of door, and the guide rail is erect on the ground of drying chamber, set up the air -blower under the guide rail, the top of drying chamber sets up the dehumidifier. The utility model is suitable for an operating time has been saved in the rapid draing of shell backing layer, has improved work efficiency.
Description
Technical field
The utility model relates to a kind of drying of casting shell, belongs to precision casting technology field.
Background technology
In precision-investment casting process, because the shell of silicasol case in shell process processed is long for drying time, cause whole Foundry Production cycle stretch-out, if shell degree of drying is inadequate, a series of casting flaw can be brought.But the backing layer every layer of general shell need carry out drying through the time of more than 24 hours, complicated shell is every layer of need 48 hours even longer time even, this has just had a strong impact on manufacturing schedule, if use rapidly-dried silica sol to make shell, although this method can shorten drying time, but cost is high, the investment shell intensity of making is low.
Current shell drying is main adopts vacuum drying still or catenary suspension type continuous vulcanization hothouse, the very flexible of shell turnover during employing catenary suspension type continuous vulcanization hothouse, and require high to acting in agreement property of shell discrepancy, drying efficiency is lower; Use vacuum drying still shell rate of drying fast, but need discontinuity to vacuumize when carrying out drying, and the investment of equipment is large, complicated operation, drying has directionality, is not suitable for volume production application.
Utility model content
The purpose of this utility model is the drawback for prior art, provides one to be applicable to the quick-drying fired mold precision casting type shell hothouse of shell backing layer, saves the working time, improve operating efficiency.
For achieving the above object, the utility model adopts following technical scheme:
A kind of fired mold precision casting type shell hothouse, it comprises the four sides vertical connection wall that forms square box and the closing door that is arranged in a wherein sidewalls between two, the offside of the closing door of described hothouse arranges constant temperature and humidity machine, the both sides adjacent with closing door are oppositely arranged many ventilating fans side by side, the ground erection guide rail of hothouse, arrange air blast under described guide rail, the top of hothouse arranges dehumidifier.
Above-mentioned fired mold precision casting type shell hothouse, the flabellum with the fan of row be arranged in parallel with angle is corresponding in both sides.
Above-mentioned fired mold precision casting type shell hothouse, arranges an observation panel at the middle part of wall.
Hothouse described in the utility model avoids the inflexible of catenary construction, and shell is come in and gone out flexibly, and mobility is high, and equipment investment is little, and production capacity is high, can meet production in enormous quantities.
In the utility model, shell is in the state of " low load with strong power " in dry run always to adopt powerful constant temperature and humidity machine to ensure, accelerates the speed to external migration of the moisture of shell inside, thus accelerates rate of drying.The fan arranged by both sides and dehumidifier setting up and down, air blast form the environment that Wind Volume high-speed circulating systems and low humidity are overlapped in left and right, upper and lower two respectively, decrease the drying time of shell, shorten the shell cycle processed, the shell cycle processed can shorten to 4-8 hour in 24 hours from traditional every layer, improves production efficiency.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1, Fig. 2 are structural representations of the present utility model,
In figure, arrow is depicted as wind direction.
In figure, each list of reference numerals is: 1, constant temperature and humidity machine, 2, fan, 3, shell, 4, closing door, 5, guide rail, 6, air blast, 7, wall, 8, observation panel, 9, dehumidifier.
Detailed description of the invention
Referring to Fig. 1 and Fig. 2, a kind of fired mold precision casting type shell hothouse, is applicable to carry out rapid draing to the backing layer of fired mold precision casting type shell.Described hothouse comprises the wall at four sides, and wherein a sidewalls arranges closing door 4, convenient discrepancy.Described wall 7 is vertically end to end between two, and form quadra, offer a square observation panel 8 at the middle part of a side walls, described observation panel 8 adopts clear glass to close, and facilitates staff to control the inner case of hothouse at any time.
In hothouse, the side relative with closing door 4 arranges a constant temperature and humidity machine 1, and described constant temperature and humidity machine 1 selects the powerful model being greater than actual needs, makes shell in dry run, be in the state of " low load with strong power ", increase gradient, increase work efficiency.Such as when hothouse area is 40m
2time, the constant temperature and humidity machine selected is 200m for being suitable for area
2model.
The both sides adjacent with closing door 4 arrange multiple stage fan 2, described fan 2 arranges many rows, often arranges two, positioned opposite side by side in both sides respectively, the flabellum often arranging two corresponding desk fans is arranged in parallel with angle, and the flabellum of fan is 10 °-45 ° with angle between the walls.When shell is carrying out in dry process, open fan, the wind of both sides forms a strong wind high-speed circulating system, improves drying efficiency.
At the ground Middle face erection guide rail 5 of hothouse, described guide rail 5 is between the fan of both sides, and for improving the quantity holding shell, guide rail can arrange multiple tracks.Needing to carry out dry shell 3 is placed in go-cart, and go-cart is placed on guide rail.
Arrange multiple stage air blast 6 in the below of guide rail 5, the top of hothouse arranges dehumidifier 9, carries out in dry process, air blast 6 and dehumidifier 9 acting in conjunction, forms upper and lower wind direction circulation and dehumidification system, is conducive to the rapid draing of shell.
