In abrasive reclaiming of the present utility model system, described cement output tank is connected in separator near on the sidewall of bottom, and the port of export of this cement output tank is tilted to lower setting, and the openend of described aspiration channel upwards arranges.
In abrasive reclaiming of the present utility model system, be provided with frame, rotary screen, funnel, reductor and motor in the described separator, described rotary screen is positioned on the described frame obliquely, described motor connects reductor, this reductor is connected with described rotary screen by shaft coupling, and described funnel is arranged at the bottom of rotary screen and is connected on the described lower spiral bidirectional conveyor.
In abrasive reclaiming of the present utility model system, described sand-falling port is connected to sand storage chamber, and the sand cylinder of sandblast operation is connected in the bottom of sand storage chamber; The bottom of described bucket elevator is to collect the sandpit that rear steel sand is used in the sandblast operation, and used steel sand passes through a tape transport to bucket elevator in the sandpit.
Based on technique scheme, abrasive reclaiming of the present utility model system has in use obtained following technique effect:
1. reduce significantly noise pollution.The utility model is that the steel sand separator that four original vibrating motors etc. form is replaced with drum-type sand screen, make material in cylinder, overturn, roll, qualified undersize is discharged through the screen cloth of cylinder cylindrical, and underproof undersize is through the terminal discharge of cylinder.
2. avoid causing dust pollution.We have increased by two aspiration channels in sand storage chamber, increased simultaneously the diameter of aspiration channel on the rotary screen, because the spiral vortex type principle of using in the separation process, steel sand can be drawn in the aspiration channel, solved well a difficult problem that produces a large amount of dust pollutions in the separation process, so that the dust collection capacity of equipment strengthens greatly.
3. avoid waste of raw materials, reduced the spoilage of equipment.Separator of the present utility model adopts the rotating centrifugal separation principle, keeps sealing state, so that raw material can not produce waste after separation; In addition, separator of the present utility model adopts the sieve formula to separate, and by columnar bolter, can improve separative efficiency and reduce the equipment loss rate, increases the service life.
Description of drawings
The structural representation of the abrasive reclaiming system when Fig. 1 is the utility model shipbuilding in the sandblast operation.
Fig. 2 is the structural representation of separator in the abrasive reclaiming of the present utility model system.
The specific embodiment
Below we when coming shipbuilding of the present utility model with specific embodiment by reference to the accompanying drawings the abrasive reclaiming system in the sandblast operation do further and elaborate; form and workflow in the hope of understand structure of the present utility model more cheer and brightly, but can not limit protection domain of the present utility model with this.
Please see Figure 1 and Fig. 2, the structural representation of the abrasive reclaiming system when Fig. 1 is the utility model shipbuilding in the sandblast operation, Fig. 2 are the structural representations of separator in the abrasive reclaiming of the present utility model system.As seen from the figure, during the utility model shipbuilding the abrasive reclaiming system in the sandblast operation structure form mainly include bucket elevator 1, on conveying worm 3, separator 4 and lower spiral bidirectional conveyor 5.
Wherein, the bucket elevator 1 of standing is connected to an end of described upper conveying worm 3 by a tube connector 2, upper conveying worm 3 is the mode level that material adopts screw rod to promote from an end to be hanged down be transported to the other end, and other end of conveying worm 3 is connected on the separator 4 by the bottom on this.
The bottom of separator 4 is connected to the middle part of lower spiral bidirectional conveyor 5, the opening that this time spiral bidirectional conveyor middle part makes progress receives the undersize that falls in the separator 4, propelling movement screw thread on the screw rod of lower spiral bidirectional conveyor 5 has two sections, the direction of rotation of two terminal screws is opposite, and intersect in the peristome office, material can be pushed to both sides respectively during rotation.Respectively be provided with a sand-falling port 7 at the two ends, bottom of lower spiral bidirectional conveyor 5.
The sidewall of separator 4 is provided with a cement output tank 6 and an aspiration channel 8, and cement output tank 6 is connected in separator 4 near on the sidewall of bottom, and the port of export of this cement output tank 6 is tilted to lower setting.The openend of aspiration channel 8 upwards arranges, and aspiration channel 8 is an air main that diameter is 35cm, and in aspiration channel 8 interior increases air-valve is arranged, and the setting of air-valve is for the ease of regulating air volume.
Be provided with in this separator 4 and be in tilted layout, be used for the rotary screen 9 that abrasive material is isolated solid dust and sand material.
In abrasive reclaiming of the present utility model system, be provided with frame, rotary screen 9, funnel, reductor and motor in the separator 4, rotary screen 9 is positioned on the frame, and motor connects reductor, and this reductor is connected with rotary screen 9 by shaft coupling.Funnel is arranged at the bottom of rotary screen 9 and is connected on the lower spiral bidirectional conveyor 5.
The inclination of above-mentioned separator intermediate roll sieve 9 is installed on the frame.Motor links together by shaft coupling through reductor and rotary screen, and the head roll sieve rotates around its axis.After material enters rotary screen, because inclination and the rotation of rotary screen make materials overturning and rolling on the compass screen surface, qualified material is discharged through the screen cloth of cylinder cylindrical as undersize, underproof material is discharged through the cylinder end as oversize.Because upset, the rolling of material in cylinder can be ejected the material that is stuck in the sieve aperture, prevents sieve pore blockade.
For recycling of steel sand in the sandblast operation, be connected to sand storage chamber in sand-falling port 7 bottoms that are connected with lower spiral bidirectional conveyor 5, the sand cylinder of sandblast operation is connected in the bottom of sand storage chamber, so that take at any time the steel sand of recovery.The sandpit of rear steel sand is used in the bottom of described bucket elevator 1 for collecting the sandblast operation, used steel sand, is promoted to get on to be convenient to process by bucket elevator 1 again and reclaims to bucket elevator 1 by tape transport in the sandpit.The sand material that needs aborning to be recovered enters sandpit, send bucket elevator to by conveyer belt, after by bucket elevator the sand material being carried as above conveying worm again, the sand material enters the steel sand separator, sand-falling port by lower conveying worm lower end enters in the sand storage chamber at last, a circulation so repeatedly.
In whole system, in order to reduce dust pollution, we have installed the part of aspiration channel as cleaner on the separator again, and cleaner includes the motor of a 90kW, cover filtering cartridge filter and a cyclone type filter vat.When recovery system is moved, the dust that is sucked by blower fan passes through cyclone type filter postprecipitation part solid dust particle, enter filtering cartridge filter (48 filter cylinders are arranged in every suit filtering cartridge filter), impact through pulse persistance, dust granules is all stayed the filter cylinder outside, be discharged in the air again through the air after the treatment and purification.
The Main Function of recovery system of the present utility model be to sand washing with the steel sand recycling that circulates, reduce the sand washing cost.Several large problem that produces when changing abrasive reclaiming in the prior art, piece-rate system use: the problems such as noise pollution, air-borne dust pollution, wastage of material, device damage rate height.Reduce widely the consequence that above-mentioned several large problem produces, in line with safety in production, the principle of protection Manufacturing Worker health has been designed rational, advanced abrasive reclaiming system.
