Description
Technical field
The utility model relates to casting technology field, especially a kind of molding sand quality on-line measuring device.
Background technology
Casting is one of main method obtaining engineering goods blank, and the quality of foundry goods directly affects the quality and performance of final products.The market competition of increasingly sharpening requires the nearly end form foundry goods that foundry enterprise produces better quality, reliability is higher, wall thickness is thinner, price is lower.Clay-bonded sand green casting is current most widely used casting method, and in its production run, the performance of molding sand has great impact to casting quality, rejection rate.Domestic foundry production line at present, the calculating of the detection of its moulding-sand property and material additional amount is different, the molding sand quality detector of supporting puddle mixer, also because the reason of the aspects such as theory and structure exists defects such as detecting inaccurate and failure rate height.
Utility model content
The problem that the utility model technology will solve is: overcome the deficiency in prior art, provides a kind of and immediately can detect moulding-sand property and the molding sand quality on-line measuring device of auto modification amount of water.
The utility model solves the technical scheme that its technical matters adopts: a kind of molding sand quality on-line measuring device, be arranged on puddle mixer side, comprise support and industrial computer, sampler for extracting sand sample from puddle mixer is connected to puddle mixer side panel, support is provided with detector, be provided with feeding tube between sampler lower end and detector, described industrial computer connects sampler and detector respectively by circuit.
Further, sand aerator is provided with between described sampler lower end discharging opening and feeding tube.
Be provided with below described support for collecting the waste discharge elephant trunk detecting rear molding sand, the import of waste discharge elephant trunk is positioned at below feeding tube.
The beneficial effects of the utility model are: the utility model can be used in the performance such as compact rate of molding and green compression strength of on-line checkingi puddle mixer Sand, and by controlling to add the water yield, molding sand compact rate of molding can be controlled, within the processing range of setting, to guarantee the consistency of performance preparing molding sand according to testing result.

Embodiment
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of molding sand quality on-line measuring device as shown in Figure 1, be arranged on puddle mixer 1 side, to sample from puddle mixer and the moulding-sand property detected at that time (comprises compact rate of molding for online, the indexs such as sand mold intensity), described pick-up unit comprises support 2 and industrial computer 3, sampler 4 for extracting sand sample from puddle mixer 1 is connected to puddle mixer 1 side panel, support 2 is provided with detector 5, feeding tube 6 is provided with between sampler 4 lower end and detector 5, sand aerator 7 is provided with between sampler 4 lower end discharging opening and feeding tube 6, described industrial computer 3 is connection detector 5 and sampler 4 respectively, to control the course of action of detector 5 and sampler 4.
Be provided with waste discharge elephant trunk 8 below described support 2, the import of waste discharge elephant trunk 8 is positioned at below feeding tube 6, for collecting the molding sand after detection and discharging.
After puddle mixer 1 is started working and is dry mixed a period of time, industrial computer 3 sends instruction, sampler 4 samples from puddle mixer 1, moulding sand sample passes through the detection mouth of feeding tube 6 to detector 5 after sand aerator 7 dozens of pines, industrial computer 3 controls the index such as compact rate of molding, sand mold intensity that detector 5 detects moulding sand sample, after the actual numerical value detected and desired value compare by industrial computer 3, according to the gap of itself and desired value, calculate to answer amount of water and control puddle mixer 1 and add water.Before this batch of molding sand system of mixing completes, pick-up unit detects the performance of molding sand by again sampling, the data that second time detects again compared with desired value, and automatic Memory needs the amount of water revised, and revises when next group sand.Except the compact rate of molding of molding sand, the gap that pick-up unit will compare between the sand mold intensity of moulding sand sample and sand mold intensity targets value when second time detects, bentonitic correction will be revised when this gap is greater than 1.0N/c ㎡, this correction be progressively carry out to ensure that bentonitic increase can not be too much.
The utility model can be used in the performance such as compact rate of molding and green compression strength of on-line checkingi puddle mixer 1 Sand, and by controlling to add the water yield, molding sand compact rate of molding can be controlled, within the processing range of setting, to guarantee the consistency of performance preparing molding sand according to testing result.
Above-mentioned embodiment is only for illustrating technical conceive of the present utility model and feature; its object is to person skilled in the art can be understood content of the present utility model and be implemented; protection domain of the present utility model can not be limited with this; all equivalences done according to the utility model Spirit Essence change or modify, and all should be encompassed in protection domain of the present utility model.
