Abstract
The utility model belongs to the field of stone processing machinery and relates to a power-removing sorter for stone dust. The utility model includes a screening tower, the air inlet at the lower part of the screening tower is connected with the outlet of the blower fan. the air outlet at the top of the screening tower is connected with the inlet of the blower fan through a cyclone dust collector, and a feed inlet is arranged at the upper part of the screening tower; a plurality of tilt screen plates are arranged in the middle of the screening tower and form a maze-like stone dust passage; a discharge port is arranged at the bottom of the screening tower and an analytic set is arranged under the air outlet; the analytic set has a rotary impeller driven by a motor and a driving mechanism. Sheet grid plates which are vertical to an impeller and are arranged in the air-out passage are evenly arranged on the impeller. The utility model not only has good powder-removing effect but also realizes the whole powder-removing process in a closed system, which reduces the pollution caused by dusts.
Description
Technical field
The utility model relates to and belongs to processing stone materials machinery, relates to a kind of aggregate chips and removes the powder refiner.
Background technology
In the road construction process, for guaranteeing construction quality, employed aggregate chips in the bitumen concrete has certain requirement to its particle diameter specification, the content of stone powder in the aggregate chips need be controlled in the lower proportion.Present employed aggregate chips generally is to obtain with the screening back through building stones are broken, and content of stone powder wherein often is difficult to reach instructions for use.The producer of many production aggregate chips is in order to reach instructions for use, normally aggregate chips is sieved with sieve, remove the stone flour of excess, its process dust flies upward on the one hand, make work under bad environment, its screening effect is also undesirable on the other hand, and screening process also can remove the big slightly aggregate chips of many particle diameters simultaneously, make in the aggregate chips ratio of various particle diameters unreasonable, still be difficult to reach instructions for use.
Summary of the invention
Technical problem to be solved in the utility model is, provides a kind of aggregate chips that can remove stone flour effectively to remove the powder refiner, makes its aggregate chips that can obtain to satisfy different construction requirements, and its production environment is polluted for a short time simultaneously, reduces working strength of workers.
Aggregate chips of the present utility model goes the powder refiner to include a screening tower, air inlet is arranged at the bottom of screening tower, it is connected by the outlet of air channel with a blower fan, air outlet is arranged at the top of screening tower, the air channel that is connected with air outlet is connected with the import of above-mentioned blower fan through a rotoclone collector, top at the screening tower has charging aperture, be mounted with the tilting sieve plate of several layers at screening tower middle part, the lower edge guiding of each layer sieve plate is the upper end-face edge of one deck sieve plate down, constitute the aggregate chips passage of " labyrinth shape ", the screening tower bottom has the discharging opening of a gravity turnover plate type, below screening top of tower air outlet, an analytical equipment is arranged, this analytical equipment has a rotary blade that is driven by motor and transmission mechanism, evenly is placed with the sheet screen of vertical installation on impeller, and screen is positioned on the air-out passage.
In the utility model use, enter in the process that the aggregate chips of screening in the tower repeatedly sieve, fall at sieve plate, upwards dispelled by powerful air-flow, stone flour and less aggregate chips rise with air-flow, and the selection of device by analysis, discharge the screening tower by air outlet, it not only has and goes the powder effect preferably, and the whole powder process of going is carried out in a closed-circuit system, has reduced the pollution of dust.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
As shown in the figure, the utility model has the screening tower 1 of a tubular, the air inlet 2 of the bottom of screening tower is connected with the outlet of blower fan 3, the air outlet 4 at the top of screening tower is connected with the import of blower fan 3 through a rotoclone collector 5, screening tower top has charging aperture 6, there is the tilting sieve plate of several layers 7 at screening tower middle part, and the lower edge guiding of each layer sieve plate is the upper end-face edge of one deck sieve plate down, constitutes the aggregate chips passage of " labyrinth shape ".The aggregate chips that enters the screening tower from charging aperture constantly falls on sieve plate, and the air-flow that is made progress dispels.The screening tower bottom is the discharging opening 8 of a gravity turnover plate type, and when the aggregate chips of piling up reached certain weight, turnover panel can be opened, and aggregate chips is fallen on the conveyer 12 of below, and when aggregate chips was less than certain amount, turnover panel was closed.There is an analytical equipment to be positioned at the below of air outlet 4, this analytical equipment has a rotary blade 10 that is driven by motor 9 and transmission mechanism, on impeller, evenly be placed with the sheet screen 11 of vertical installation, screen is positioned on the passage of air-out, variation by wheel speed, can change the dynamic clearance of screen, reach the purpose that the dust that only allows specified particle diameter passes through, thereby guarantee to go the ratio of various particle diameters in the aggregate chips behind the powder can satisfy instructions for use.
