The evanescent mode sand processing system comprises a drum sand sieving machine, a vibration conveyor trough, a belt-type suspended magnetic separator, a heat-resistant bucket elevator, two intermediate sand bins, a dust removing device, a transitional sand hopper, a pneumatic conveyor, two sand hoppers above a swing table, and a rain-type sand feeder, wherein the vibration conveyor trough and the belt-type suspended magnetic separator are arranged at the rear side of the drum sand sieving machine; the heat-resistant bucket elevator is arranged at the rear sides of the vibration conveyor trough and the belt-type suspended magnetic separator; the two intermediate sand bins are arranged at the rear side of the heat-resistant bucket elevator; the dust removing device is arranged at the rear sides of the intermediate sand bins; the transitional sand hopper is arranged at the rear side of the dust removing device; the pneumatic conveyor is positioned at the rear side of the transitional sand hopper; the sand hoppers above the swing table are arranged at the rear side of the pneumatic conveyor; and the rain-type sand feeder is arranged at the rear sides of the sand hoppers above the swing table. The evanescent mode sand processing system is characterized by further comprising a programmable logic controller (PLC) system and a dust removing system; the dust removing device is a boiling bed cooling dust removing device and comprises a cold water circulating system and a high-pressure centrifugal fan; and a central sand bin is arranged between the transitional sand hopper and the pneumatic conveyor. Due to the dust removing device and the dust removing system, the evanescent mode sand processing system is good in effect, reasonable in design, convenient and reliable to control and use and high in working efficiency.
Description
Technical field:
The present invention relates to evaporative pattern placingJi Shu field, specifically a kind of evaporative pattern sand preparing system.
Background technology:
Technology of EPC is that the foamed plastic model bonding similar to the casting dimension shape is combined into model cluster, after brushing refractory coating and oven dry, be embedded in vibration molding in the dried quartz sand, pour into a mould liquid metals under certain condition, make the model gasification and occupy modal position, solidify the rear method that forms required foundry goods of cooling.For lost foam casting, multiple different call is arranged.Domestic main call has " dry sand cavityless casting ", " vacuum full mold casting ", is called for short the EPC casting.Lost foam casting process comprises white area, black area and yellow district technique, and in existing Technology of EPC, in the sand processing technique of black area, control and operation is inconvenient, and dust removing effects is relatively poor, and dedust device dedust effect is undesirable, and the return sand conveying device is unreasonable.
Summary of the invention:
Technical problem to be solved by this invention is to provide a kind of convenient operation and control, the evaporative pattern sand preparing system that the sand treatment effect is good.
Technical problem to be solved by this invention adopts following technical scheme to realize:
A kind of evaporative pattern sand preparing system, comprise roller sand screener, the vibration chutes and the belt that are located at the roller sand screener rear side hang magnetic separator, be located at the heat-resisting bucket elevator that vibration chutes and belt hang the magnetic separator rear side, be located at 2 middle sand storages of heat-resisting bucket elevator rear side, the dedust device of sand storage rear side in the middle of being located at, be located at the transition sand hopper of dedust device rear side, be located at the Pneumatic conveyer of transition sand hopper rear side, be located at 2 plain bumper tops of Pneumatic conveyer rear side sand hopper, the rear side of plain bumper top sand hopper is provided with rain type and adds the sand machine, it is characterized in that: also comprise PLC control system and dust pelletizing system; Described dedust device is ebullated bed cooling dedust device, and comprises cold water circulating system and centrifugal high pressure fan; Be provided with the center sand storage between described transition sand hopper and the Pneumatic conveyer.
Described plain bumper top sand hopper is set up in parallel at the Pneumatic conveyer rear, just can be set to like this station of two filling moulding at the rear that rain type adds the sand machine, can greatly improve the task performance of filling moulding.
Described dust pelletizing system adopts the terylene needled felt filtrate.
Sand storage becomes series connection setting in the middle of described 2.
The dedust device adopts ebullated bed cooling dedust device among the present invention, disposes cold water circulating system, can effectively reduce temperature and the ash of return sand; Return sand after the processing adopts Dense Phase Pneumatic Conveying, has both improved working environment, makes things convenient for again system and layout; The pulse backblowing sack cleaner of dust pelletizing system adapted adopts the advanced novel filtrate of terylene needled felt, and filter efficiency improves 30% than ordinary filter; Control system adopts the PLC centralized Control, and establishes the flowsheeting demonstration, can select several modes of operation such as automatic, manual, very reliable convenience.
The invention has the beneficial effects as follows: dedust device of the present invention and dust pelletizing system are effective, reasonable in design, control easy to use and reliablely, and task performance is high.
