Abstract
The utility model relates to an energy-saving mold shell drying chamber for investment casting. The energy-saving mold shell drying chamber comprises a closed shell, wherein a perforated separating plate is arranged in the shell for dividing the inside the shell into an upper layer and a lower layer, the shell is provided with doors capable of being opened and closed and corresponding to the layers, a tray for containing the mold shell is arranged on a frame structure, a vent pipe is arranged at the lower part of the lower layer inside the shell, at least one exhaust port is arranged at the upper part of the upper layer of the shell, an air feed pump is arranged outside the shell, an outlet of the air feed pump is communicated with the vent pipe, a control valve is arranged between the outlet of the air feed pump and the vent pipe, a humidity sensor and a temperature sensor are arranged in the upper layer of the shell and are connected with a controller outside the shell, and an electric heating device is also arranged on the inner side wall of the upper layer of the shell.
Description
Technical field
The utility model belongs to model casting field, refers to especially the energy-saving drying chamber that in model casting, formwork drying is used.
Background technology
In model casting field, formwork is after carrying out last back-up coat stucco, and step just can dewax after needing to be dried.And also need to carry out formwork drying before firing to formwork after dewaxing mould.If do not having dried in the situation that, can there is crackle or distortion in formwork.Therefore,, in model casting field, the dry of formwork is that the formwork that guarantees the later stage is fired, or even the important procedure of final casting.
Now carrying out formwork drying adopts in two ways substantially:
Be a natural drying mode, be about to formwork to be dried and be placed in shady and cool ventilation place and carry out natural dryingly, this drying mode is generally can adopt in the situation that production scale is little.Larger enterprise does not now adopt this drying mode substantially, is mainly because natural drying mode is subject to the impact of natural conditions larger, and such as southern intermittent drizzles in the rainy season are during season, under field conditions (factors), the dry of formwork cannot complete substantially.
Be a human assistance drying mode, because in to formwork drying process, best baking temperature is 20 ℃-30 ℃; If temperature extends lower than 20 ℃ arid cycle; If higher than 30 ℃ formwork when firing, can there is loose situation.In order to improve rate of drying, enhance productivity, in oriented hothouse, forced ventilation is accelerated dry run, is adopting means of ventilation really to improve the rate of drying of formwork.But also there is certain defect in this mode, be exactly wind speed when excessive, can in formwork, there is different drying layers, the form strength after firing is affected because of the different drying layers of formwork.
Utility model content
The purpose of this utility model is by the dry formwork drying device of existing employing forced ventilation being proposed to technological improvement, by the technical program, effectively improving outside rate of drying, there is no that energy consumption occurs.
The utility model is achieved through the following technical solutions:
The energy-conservation formwork drying of a moltening mold castings chamber, includes the housing of sealing, in housing with baffle for separating with holes for two-layer up and down, the corresponding every one deck of housing with can switch, in frame structure, be provided with the pallet of placement formwork; In housing, the bottom of lower floor is provided with ventilation duct, and the top on housing upper strata is provided with at least one exhaust outlet; At housing, be outside equipped with air feed pump, air feed delivery side of pump is communicated with ventilation duct; Between air feed pump outlet and ventilation duct, be provided with control valve; In housing upper strata, being provided with humidity sensor is connected with temperature sensor and with the controller outside housing; Housing upper strata madial wall is also provided with electric heater unit; Described controller is connected with control valve with electric heater unit.
Described ventilation duct includes at least one supervisor, be responsible for being vertically connected with at least two and being in charge of, and is connected with at least one with being in charge of vertical gas distribution pipe on each is in charge of.
In described housing, the height of lower floor is less than the height on upper strata.
Described controller includes radiator valve; Radiator valve is connected with control valve and heater.
Described air feed pump porch is provided with dehumidifier.
On described housing, be provided with heat-insulation layer.
The beneficial effects of the utility model are:
By the technical program, can in ventilation situation, effectively improve formwork drying speed, and the wind speed ventilating reduction, indoor air humidity keeps dry simultaneously.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
By specific embodiment, describe the technical solution of the utility model in detail below, should be understood that, following embodiment is only exemplary, only can be used for explaining and explanation the technical solution of the utility model, and can not to be interpreted as is the restriction to technical solutions of the utility model.
As shown in Figure 1, the energy-conservation formwork drying of a kind of moltening mold castings chamber, include the housing of sealing, housing is outside equipped with heat-insulation layer, heat-insulation layer material is prior art, in housing with baffle for separating with holes for two-layer up and down, at the corresponding every one deck of housing with door that can switch, for placement and taking-up formwork.Upper strata 1, with multistory frame structure 11, is provided with the pallet of placing formwork 13 to be dried in frame structure 11 in housing, and in housing, lower floor 10, with a story frame structure 12, is provided with the pallet of the formwork 15 that placement cast in frame structure 12.
In housing, the bottom of lower floor 10 is provided with ventilation duct 6, ventilation duct 6 includes at least one supervisor, be provided with in the present embodiment three parallel supervisors, on supervisor, being vertically connected with 10 is in charge of, on each is in charge of, be connected with two mutually vertically and with being in charge of vertical gas distribution pipe, finally the gas outlet of each gas distribution pipe all or one-tenth parallel with the bottom surface of housing not higher than 45 degree angles.
In housing, the top on upper strata 1 is provided with two exhaust outlets 9; At housing, be outside equipped with air feed pump 5, the outlet of air feed pump 5 is communicated with ventilation duct 6; Between air feed pump 5 outlets and ventilation duct 6, be provided with control valve 4; In housing, being provided with humidity sensor 7 is connected with temperature sensor 8 and with the controller 3 outside housing; In housing, be also provided with electric heater unit 2; Described controller 3 is connected with control valve 4 with electric heater unit 2.
