Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Figure 1, a kind of molding sand quality is online to be detected and automatic humidity control system, described on-line detecting system is arranged on puddle mixer, described on-line detecting system comprises controller, and described controller is connected 12 with humidity sensor 9, temperature sensor, compact rate of molding pressure unit 7 is connected with intensity pressure unit 8; Described automatic humidity control system is arranged on supplying on sand belt conveyor before moulding machine, and described automatic humidity control system comprises automatic watering apparatus 11, and described automatic watering apparatus 11 is connected with controller 10.Humidity sensor 9 and temperature sensor 12 pass to controller 10 by the humidity and temperature of detection, and controller 10 is controlled automatic watering apparatus, and automatic watering regulates the humidity of sand.
Further, as shown in Figure 2, described automatic watering apparatus 11 comprises water inlet 1 and water delivering orifice 5, described water delivering orifice 5 is connected with puddle mixer, between described water inlet 1 and water delivering orifice 5, water pipe 6 is installed, described water pipe 6 comprises two branch roads in parallel, is separately installed with thick control valve 3 and essence control valve 4 on described branch road, on described water pipe 6, near one end of water inlet 1 and one end of close water delivering orifice 5, a flowmeter 2 is respectively installed.Wherein slightly control valve 3 for pneumatic angle pedestal valve DN25, essence control valve 4 is pneumatic angle pedestal valve DN40, and flowmeter 2 is installed on described water pipe, and the water yield that can be metered into by flowmeter 2, adds hydromining and add water mode with slightly adding two kinds, water and finishing water.
Further, described controller 10 is the single-chip microcomputer for data acquisition and processing (DAP).After single-chip microcomputer image data, data are processed, obtained the evaporation curve about temperature and humidity of sand, then according to the weighing scale of evaporation curve and sand, calculate the weight of the required water adding, and then control amount of water.The water yield that can be metered into by flowmeter 2, adds hydromining and adds water mode with slightly adding two kinds, water and finishing water.
The concrete operations that slightly add water and finishing water are: in puddle mixer, add after sand, automatic watering apparatus adds water for the first time, slightly add water, the method for determination of amount that slightly adds water comprises two kinds: (1) just started shooting or shut down after restart, amount of water is according to the sand amount that once adds of puddle mixer and the empirical value of compact rate of molding target setting, (2) complete after a mulling, using approximately 75% amount of the total amount of water of this mulling as thick amount of water; In mulling process, by sampling for the first time, detect compact rate of molding and the wet strength of sand, with setting value comparison, if measured value is lower than the lower limit (being that amount of water is inadequate) of compact rate of molding scope, under the regulation and control of single-chip microcomputer, carry out finishing water, after mixing certain hour, sampling detects again, and finishing water is until compact rate of molding and wet strength reach setting value so repeatedly.And, automatic humidity control system is by detecting the humidity and temperature of sand, data are passed to single-chip microcomputer, after single-chip microcomputer is processed data, automatically adjust and control amount of water, reach the object of real-time detection and control molding sand quality, control humidity and the compact rate of molding of molding sand comprehensively, guarantee molding sand quality performance comprehensively.
The above; be only the specific embodiment of the present invention, protection scope of the present invention is not limited to this, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement, within all should being encompassed in protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain that claim was defined.
