The utility model solves the technical scheme that its technical problem adopts: stretch conical tube type grader in one, there is scroll casing type classification main body, the front/rear end of described scroll casing type classification main body is respectively arranged with side spiral case, Taper Pipe is stretched in each side spiral case all has, stretch in described between Taper Pipe and scroll casing type classification main body and be provided with regulating orifice plate, on the outboard sidewalls stretching Taper Pipe in described and on the inwall of scroll casing type classification main body, be provided with wear resistant ceramic chip.
Further specifically, described scroll casing type classification main body, side spiral case and in stretch Taper Pipe central point be located on the same line; The left side of scroll casing type classification main body is provided with the particle input channel be connected with outside feed hopper, and bottom is provided with the coarse fodder output channel be connected with outside cinder storehouse, is provided with secondary air inlet between scroll casing type classification main body and coarse fodder output channel; The right side of described side spiral case is provided with the fines output channel that grey storehouse thin with outside is connected; The lateral surface of two side spiral cases is provided with opens side door soon, is provided with movable guide vane in the inner chamber of scroll casing type classification main body.
Further specifically, the shell face of described scroll casing type classification main body is provided with the governor motion for regulating secondary air inlet intake, described governor motion comprises scale plate, L shape pointer, handle and bolt, the head of described bolt withstands the middle part of handle, handle is connected with the afterbody of L shape pointer, the head of L shape pointer does arc rotary motion on scale plate, is provided with stop pad between the installing hole of described handle and scroll casing type classification main body.
The beneficial effects of the utility model are: stretch conical tube type grader in of the present utility model and have the following advantages:
One, cone technique is stretched in employing, the volute whirlwind effect of the centrifugal motion of particle in grader and volute negative-pressure ward no longer influences each other destruction of balance, overcome two lateral enrichment effects of conventional volute grader well, service life of equipment and fineness are adjusted arbitrarily and fineness agonic realization in both sides is guaranteed;
Two, when the sufficient centrifugal motion of particle does not affect by volute suction, under the secondary of powerful Secondary Air blows, the efficiency of separation of grader can be increased to 92% from original 85%.

Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As shown in Figure 1, Figure 2 and Figure 3, inside stretch conical tube type grader, there is scroll casing type classification main body 1, the front/rear end of described scroll casing type classification main body 1 is respectively arranged with side spiral case 2, stretch Taper Pipe 3 in each side spiral case 2 all has, the outboard sidewalls stretching Taper Pipe 3 in described is provided with wear resistant ceramic chip 14; Scroll casing type classification main body 1, side spiral case 2 and in stretch Taper Pipe 3 central point be located on the same line; The left side of scroll casing type classification main body 1 is provided with the particle input channel 4 be connected with outside feed hopper, bottom is provided with the coarse fodder output channel 5 be connected with outside cinder storehouse, is provided with secondary air inlet 6 between scroll casing type classification main body 1 and coarse fodder output channel 5; The right side of described side spiral case 2 is provided with the fines output channel 7 that grey storehouse thin with outside is connected; The lateral surface of two side spiral cases 2 is provided with opens side door 8 soon, is provided with movable guide vane 9 in the inner chamber of scroll casing type classification main body 1.As depicted in figs. 1 and 2, the shell face of described scroll casing type classification main body 1 is provided with the governor motion for regulating secondary air inlet 6 intake, described governor motion comprises scale plate 10, L shape pointer 11, handle 12 and bolt 13, the head of described bolt 13 withstands the middle part of handle 12, handle 12 is connected with the afterbody of L shape pointer 11, and the head of L shape pointer 11 does arc rotary motion on scale plate 10.
As shown in Figure 2, the inwall of described scroll casing type classification main body 1 is provided with wear resistant ceramic chip 14, and wear resistant ceramic chip 14 increases the anti-wear performance of scroll casing type classification main body 1 inner chamber.Stretch in described between Taper Pipe 3 and scroll casing type classification main body 1 and be provided with regulating orifice plate 15, the replacing of regulating orifice plate 15 so that be provided with in different-diameter size and stretch Taper Pipe 3 in scroll casing type classification main body 1.
