Referring to fig. 1, an aluminum scrap collecting system comprises a dust removing box body 2, wherein the side wall of the dust removing box body is provided with an air inlet of the dust removing box body, the top of the dust removing box body is provided with a dust removing fan 5, the air inlet of the dust removing fan 5 is provided with an air inlet screen 4, the air inlet screen 4 is arranged at the upper part of the dust removing box body 2, the aperture of the air inlet screen 4 is not more than 80% of the diameter of an aluminum scrap circumcircle, an air outlet of the dust removing fan 5 is provided with an air exhaust box 6 communicated with the air exhaust box, and the bottom of the air exhaust box 6 is provided with at least one air exhaust box air outlet; an air exhaust screen 7 is arranged at the air outlet of the air exhaust box, the longitudinal section of the air exhaust screen 7 is rectangular, the upper end and the lower end of the air exhaust screen are open, and the lower end of the air exhaust screen extends into a chip removal box 8 which is arranged below the air exhaust box 6; the top of the chip removal box 8 is open and is used for collecting external aluminum chips 9; the aperture of the air exhaust screen 7 is smaller than that of the air inlet screen 4.
The utility model discloses utilize the negative pressure that dust exhausting fan 5 produced, make wind bring the aluminium bits into dust removal box 2 in, utilize built-in air inlet screen 4's isolation, furthest keeps off the aluminium bits before dust exhausting fan air intake for most aluminium bits are collected in dust removal box 2. Because the aperture of the built-in air inlet screen 4 is smaller and allows a large wind speed, the length of the air inlet screen 4 can be reduced, the overall dimension of the dedusting box body 2 is smaller than the cyclone dedusting volume, the consumption of raw materials of equipment is reduced, and the cost is saved.
In addition, the built-in air inlet screen 4 actively collects most of the aluminum scraps at the bottom of the dust removal box body 2, and the small aluminum scraps which have smaller apertures than those of the built-in air inlet screen 4 enter the air exhaust screen 7 through the dust removal fan 5. Therefore, the air exhaust screen 7 can pass through slightly fast air, and simultaneously, the size of the aperture of the air exhaust screen 7 is reduced, so that the overall dimension of the air exhaust device can be reduced, the consumption of raw materials of equipment is reduced, and the cost is saved.
The utility model is also provided with an air inlet baffle 3 inside the dust removing box body 2 and in front of the air inlet screen 4, on one hand, the aluminum scraps at the air inlet of the dust removing box body can directly collide with the air inlet baffle 3, the speed of the aluminum scraps is reduced, and the collection of the aluminum scraps is convenient; on the other hand, the aluminum scraps at the air inlet can be prevented from directly contacting with the built-in screen 4 to cause blockage.
In order to let the aluminium bits along the outer wall friction of built-in screen cloth 4, reduce speed, and then reduce screen cloth blocking's risk, the utility model discloses establish air inlet screen cloth 4's bottom into seal structure, with the side direction of sieve mesh setting at air inlet screen cloth 4.
The air inlet screen 4 of the utility model is of a folding structure similar to a ridge shape, preferably a rectangular wave shape.
In order to reduce the speed of 5 rear end aluminium bits of dust exhausting fan, make the aluminium bits collect in case 6 of airing exhaust completely, the utility model discloses an air exhaust screen 7's length is greater than air inlet screen 4's length to increase the area of airing exhaust.
The bottom of the dust removal box body 2 is also provided with a detachable aluminum scrap collecting box so that the internal aluminum scrap 10 falls into the box body, and the collection and the cleaning of the aluminum scrap are facilitated.
In order to reduce the risk of screen cloth jam, the utility model discloses a dust exhausting fan 5 adopts variable speed dust exhausting fan 5 to realize dust exhausting fan 5's variable speed operation. The speed of the dust removal fan 5 is adjusted to adjust the speed of the aluminum scraps, so that more aluminum scraps fall to the bottom of the dust removal box body 2.
Through experimental comparison, the dust removal system has higher dust removal efficiency than a cyclone dust removal system in view of the actual working effect of equipment; on the premise of ensuring the recovery efficiency of the aluminum scraps, the material consumption of equipment can be obviously reduced, and the cost is saved. The utility model improves the aluminum scrap recovery efficiency by optimizing the structure of the dust removal system; the aluminum scraps can be collected in the scrap collecting box at the front end of the dust removing fan 5 to the maximum extent, so that the dust removing efficiency is improved, the overall size of the equipment is reduced, and the cost is saved; in addition, the dust removal system is more environment-friendly and cleaner.
The working principle of the utility model is as follows:
dust exhausting fan 5 during operation makes dust removal box 2 in form the negative pressure (be less than standard atmospheric pressure), and wind just can follow the air intake and get into like this, and the import wind is taking the aluminium bits to enter into dust removal box 2 from air-supply line 1 in, because inertia, the aluminium bits can collide on air inlet baffle 3, makes the aluminium bits energy loss that gets into, and reduce speed, aluminium bits have some to fall into dust removal box 2 bottom like this, and this is that the aluminium bits are collected for the first time.
Following the first time aluminium bits and collecting the back, there is some aluminium bits not directly to fall into dust removal box 2 bottom, but along with the direction motion of import wind continuation to dust exhausting fan 5, this part aluminium bits can collide built-in air inlet screen cloth 4 on, the aperture of screen cloth is got through calculation, is less than most aluminium bits circumcircle, in order to guarantee the air permeability, the screen cloth aperture can not be too little. Because the bottom of the built-in air inlet screen 4 is sealed, the screen blockage caused by direct frontal collision of aluminum scraps due to overhigh speed is avoided. Built-in air inlet screen cloth 4 is the side trompil, in order to let the aluminium bits along the friction of 4 outer walls of air inlet screen cloth, reduce speed also can reduce the jam of air inlet screen cloth 4. When the dust removal fan 5 works, most of aluminum scraps entering from the air inlet can move irregularly in the space between the built-in air inlet screen 4 and the air inlet baffle 3, and when the speed of the dust removal fan 5 is low or stopped, the aluminum scraps in the dust removal fan can directly fall into the bottom of the dust removal box body 2, so that the aluminum scraps are collected for the second time.
Because the influence of uncertain factors can form aluminum scraps of which the circumscribed circle is smaller than the aperture of the built-in air inlet screen 4 when the sawing machine saws the aluminum profile, when the dedusting system works, a small part of the aluminum scraps pass through the built-in air inlet screen 4 and enter the exhaust box 6 through the dedusting fan 5, the movement speed of the aluminum scraps is still high, and in order to reduce the speed of the aluminum scraps at the rear end of the dedusting fan 5, the speed reduction of the aluminum scraps at the rear end of the dedusting fan 5 can be realized by increasing the air exhaust area, so that the aluminum scraps can be completely collected in the exhaust box 6 by enabling the length of the exhaust screen 7 to be larger than that of the built-in air inlet screen 4; in addition, the aperture of the exhaust screen 7 is selected to be smaller, so that the aluminum scraps can be further ensured to be completely collected in the exhaust box 6.
Finally, the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions, and all of them should be covered by the scope of the claims of the present invention.
