Description

Combined type granule recovery unit
Technical Field
The invention relates to the technical field of sand blasting processes, in particular to a composite type particle material recycling device.
Background
The sand blasting is to form a high-speed spray beam to spray particles (copper ore sand, quartz sand, carborundum, iron sand and sea sand) to the surface of a workpiece to be treated at a high speed by using compressed air as power, so that the appearance or the shape of the outer surface of the workpiece is changed, and the surface of the workpiece obtains certain cleanliness and different roughness due to the impact and cutting action of an abrasive on the surface of the workpiece, so that the mechanical property of the surface of the workpiece is improved, the fatigue resistance of the workpiece is improved, the adhesive force between the workpiece and a coating is increased, the durability of a coating is prolonged, and the leveling and decoration of a coating are facilitated.
The traditional granule recovery mode is divided into two independent modes: one is a recovery device using pneumatic conveying, and the other is a recovery device using mechanical conveying.
Wherein, use the pneumatic conveying recovery mode, its recovery principle is: honeycomb sand suction floor → conveying pipeline → sand dust separator → sand blasting tank → spray gun → particulate matter collecting device. It has the following disadvantages: 1) the foundation construction cost is high, a honeycomb floor needs to be laid on the recycling ground by adopting a recycling mode of a particulate matter collecting device, and a foundation with the depth of 0.8-1.2 m needs to be manufactured generally; 2) the use cost is high, the traditional honeycomb floor recovery mode can achieve the purpose of completing automatic recovery only by fully spreading the particle collecting device, if the honeycomb floor is not fully spread, the particles fall on the ground or the depth of a foundation is increased, and the recovery mode of the fully spread particle collecting device requires that the air volume of a centrifugal fan is larger and the operating power of the fan is higher; 3) the position of sand suction pipeline is not flexible, adopts honeycomb sand suction floor recovery mode, and in order to guarantee particulate matter recovery effect, the position of general sand suction pipeline is more fixed, and the adjustment range is little, influences recovery plant's arrangement.
Wherein, use mechanical type recovery mode, its principle is: a scraper (or a particulate matter conveying device such as a screw conveyor and a belt conveyor) → a bucket elevator → a classifier → a sand storage box (or a sand blast tank) → a shot blast (or a spray gun) → a scraper (or a screw conveyor and a belt conveyor). It has the following disadvantages: 1) the pit depth of the equipment is deep, the capital construction cost is high, although the equipment adopts a scraper conveyor to reduce the partial foundation depth of the ground recovery equipment to 200-400mm, a spiral conveyor (or a belt conveyor) and a bucket elevator are also needed behind the scraper conveyor, the foundation depth of the bucket elevator is generally 2.5-3.6 meters, and the foundation needs to be subjected to waterproof treatment; 2) the failure rate is high, the halt maintenance time is long, the maintenance cost of the equipment is high, and because all mechanical conveying equipment consists of a motor, a speed reducer, a bearing, a belt, a chain sprocket, a gear and other parts, on a particulate matter recovery site, particulate matters splash everywhere, dust flies everywhere, and the working condition is extremely poor, the failure rate of the equipment is high, the halt maintenance time is long, and the maintenance cost of the equipment is high.
Therefore, there is a need for improvements in the prior art.
