Detailed description of the invention
The present invention is a kind of dust sand grains piece-rate system, as shown in Figure 1, comprise the separation bin 1 that its upper end is provided with charging aperture, in described separation bin 1, stock guide 2 is installed, this stock guide 2 vertically arranges from the right positions of charging aperture and the upper part of separation bin 1 is divided into two Room, left and right, namely from the material that charging aperture enters, first enters from the left room on separation bin 1 top, again under the suction of extension set, fibre dust enters the right ventricle on separation bin 1 top from the bottom of stock guide 2.Described stock guide 2 is the adjustable angle stock guide 2 that can rotate around its upper end tie point, and according to the gravity of wind-force and fibre dust, the adjustable angle scope of described stock guide 2 is 5 ~ 20 ° to the right, is preferably and is tilted to the right 15 °.The length of stock guide 2 also directly affects the separating effect of fibre dust in addition, and the length of stock guide 2 is long, and fibre dust, because of by the stop of stock guide 2, adds Action of Gravity Field, together down drops with sand grains, can not be recycled; Length as stock guide 2 is too short, then sand grains is under wind-force effect, is also recycled in fibre dust, can not be separated, and affects the recycling of fibre dust.In the preferred embodiment, the length of described stock guide 2 is 1/2 ~ 3/5 of separation bin 1 length.The upper end of described stock guide 2 is connected with a regulating handle, and this regulating handle passes separation bin 1 upper end, is convenient to the angle regulating stock guide 2.
Be connected with a fibre dust recovery tube 3 in the upper end, right ventricle of separation bin 1, be provided with blower fan 4 in the outlet of fibre dust recovery tube 3, this blower fan 4 exports connection one fibre dust and reclaims room 5.Then be connected with sand grains in the lower end of separation bin 1 and reclaim room 6.
Separation bin 1 and/or fibre dust recovery official offer air inlet 7.Number and the position of air inlet 7 are extremely important to separating effect, directly affects the up flowing of fibre dust, to enter the effect of fibre dust recovery tube 3; And the sinking effect of sand grains.In the preferred embodiment, described air inlet 7 is 3, and each air inlet 7 is equipped with volume damper 8.3 air inlets 7 are opened in the top on the left of separation bin 1 respectively, and the middle part on the right side of separation bin 1, on fibre dust recovery tube 3.The optimum position being wherein opened in the air inlet 7 on the top on the left of separation bin 1 is distance charging aperture 20cm, is opened in the lower end of the axis of the air inlet 7 at the middle part on the right side of separation bin 1 and stock guide 2 in the same horizontal line.
Described charging aperture connects a feed pipe 9 vertically arranged, feed pipe 9 is provided with charging rotary valve 10, and feed pipe 9 is bending, can play certain centrifugation to fibre dust and sand grains.
Described separation bin 1 is venturi tube structure, and its lower end is provided with blow-off valve 11.Venturi tube structure can make wind, fibre dust and sand grains fully mix as early as possible, also can break up fibre dust and sand grains, and then improves separating effect and efficiency.
The outer wall of separation bin 1 is also provided with observation window 12, and this observation window 12 is just to stock guide 2, so that workman observes the separation case of fibre dust and sand grains, and then regulates the angle of stock guide 2 according to separation case.
