Description

Lost foam casting sand treatment equipment

Technical Field

The utility model relates to a casting field especially relates to a novel treatment facility of lost foam casting sand.

Background

The conventional lost foam sand treatment is to treat the sand for casting circulation by using equipment such as a roller, a lifting machine, a magnetic separator, a dust remover and the like, so that the sand can be recycled although the treatment can be carried out.

However, the conventional lost foam sand treatment equipment is expensive, large in occupied area, complex in process, low in treatment efficiency, high in power consumption, multiple in electrical equipment, and inconvenient to use, and needs to be maintained frequently.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome prior art not enough, provide a lost foam casting sand treatment facility that area is few, convenient to use, with low costs.

The technical scheme of the utility model is that: a lost foam casting sand handling apparatus comprising: the sand shakeout device comprises a shakeout device, a sand warehouse, a vacuum negative pressure pipeline, a distributor, a vibrating screen, a screw conveyor, a vacuum pumping pipeline, a molding sand warehouse and a sand suction device, wherein the sand warehouse is fixed at the bottom of the shakeout device, a vacuum pumping pipeline is arranged in the sand warehouse, one end of the vacuum pumping pipeline is fixed at the top of the sand warehouse and is fixedly connected with the vacuum negative pressure pipeline, the other end of the vacuum pumping pipeline enters the distributor, the vibrating screen is arranged at the bottom of the distributor, the four corners of the vibrating screen are fixed on the ground, one end of the sand suction device is connected with the bottom end of the vibrating screen, the other end of the sand suction device is connected with the molding sand warehouse, the screw conveyor is.

The sand shakeout device and the sand warehouse are trapezoidal, and are wide at the top and narrow at the bottom.

The utility model discloses through the knockout, lost foam casting sand falls into the sand storehouse, takes out the pipeline of managing to find time through vacuum negative pressure pipeline, gets into the distributor, utilizes distributor control knockout speed, and the reentrant shale shaker vibrates, screens the back, through inhaling the sand ware, takes out the molding sand storehouse with the sand that falls into the bottom after screening, by screw conveyer output, just can carry out next cycle and use. Meanwhile, the waste residue which is not used is discharged along with the vibration through the residue discharge port at the upper part of the vibrating screen under the vibration action of the vibrating screen.

The utility model discloses owing to cancelled equipment such as cylinder, lifting machine, whole equipment takes up an area of and only is within 10 meters 5 meters, and the sand cooling roller that the mould sand was handled is just taken up an area of to reach more than 15 meters 5 meters to the tradition disappearance, has practiced thrift area. And the operation and use are convenient, the number of electrical equipment is small, the use, maintenance and repair cost is low, and the manpower is saved.
