The high-speed classifier comprises a motor, an upper tank and a lower tank, wherein a classification wheel is arranged in the upper tank; a feed pipe is arranged in the lower tank; a discharge reverse flushing sleeve is additionally fixed in the upper tank, and comprises an outer pipe, an inner pipe, a left end ring and a right end ring; the outer pipe coats outside the inner pipe; a jacket is formed between the inner pipe and the outer pipe; the left and right ends of the jacket are respectively closed by the left end ring and the right end ring; an annular groove is additionally formed in the left end ring; a lap of small holes is circularly formed in the groove; the small holes are communicated with the groove and the jacket; and the bottom of the classification wheel is directly and fixedly connected with the output end of a motor, and the top of the classification wheel is embedded in the groove. Through the setting of the discharge reverse flushing sleeve, the classifier can continuously flush away a material fed between the classification wheel and a discharge pipe by external clean air in the working condition, so that the in-situ cleaning effect is achieved, the continuous working time of the classifier is prolonged, and the production efficiency is improved.
Description
Technical field
The present invention relates to a kind of grader, especially a kind of high-revolving grader, sieves for crushing rear material.
Background technology
As everyone knows, grader is for the screening to the material of different-grain diameter, the grading wheel of grader rotates, for tumbler, the discharge nozzle of grader is static, is static element, between tumbler and static element, there is gap, if this gap is too large, easily cause material to enter in a large number in gap and form and pile up, cause grading wheel to rotate even burn-down of electric motor of difficulty; Therefore; existing grader is very little by the slit design between grading wheel and discharge nozzle conventionally; certain like this effect that prevents that large granular materials from entering that played; but because grader is in work; still have unavoidably short grained material and enter into gap, therefore, after grader work a period of time, have to the gap between grading wheel and discharge nozzle to be cleaned; this cleaning process must be shut down dismounting, will affect production efficiency thus.
Summary of the invention
The present invention is directed to the problems referred to above, object is to provide a kind of high speed sorting, can in non-stop-machine situation, complete the cleaning works to the gap between grading wheel and discharge nozzle, thereby enhance productivity.
For achieving the above object, technical scheme of the present invention is: a kind of high speed sorting, comprise motor, upper box, lower box, in upper box, be provided with grading wheel, in lower box, be provided with feed pipe, in upper box, be also fixedly installed a discharging recoil air-casing, described discharging recoil air-casing one end is inner at upper box, the other end is outside at upper box, described discharging recoil air-casing comprises outer tube, inner tube, left end ring and right-hand member ring, outer tube sleeve is in interior tube outside, between outer tube and inner tube, form chuck, two ends, chuck left and right are respectively with left end ring and right-hand member ring seal, on described left end ring, be also provided with an annular groove, on groove, be equipped with a circle aperture, described aperture communication groove and chuck, the bottom of grading wheel is directly fixedly connected with the output of motor, the top of grading wheel is embedded in groove, on described outer tube, be also provided with at least one air inlet, described air inlet is in upper box outside.
As the further setting of such scheme, between upper box and lower box, be also provided with a cyclone separator.
As the further setting of such scheme, on described cyclone separator, be provided with a pass air-valve.
As the further setting of such scheme, on right-hand member ring, be also provided with screw.
The invention has the beneficial effects as follows: the setting of discharging recoil air-casing of the present invention, can allow grader by entering material between grading wheel and discharge nozzle, with outside clean air, continue to wash away under in working order, reached the effect of original position cleaning, extend the time of grader continuous firing, improved production efficiency.

In figure: motor 1, upper box 2, lower box 3, cyclone separator 4, pass air-valve 41, discharging recoil air-casing 5, outer tube 51, inner tube 52, chuck 53, air inlet 54, baffle plate 55, left end ring 56, groove 561, aperture 562, right-hand member ring 57, screw 571, feed pipe 6, grading wheel 7.
Arrow in Fig. 2 is gas flow.
The specific embodiment
Below in conjunction with accompanying drawing, and in conjunction with the embodiments, the present invention is described further.
Embodiment: as shown in Fig. 1 ~ 4, a kind of high speed sorting, comprise motor 1, upper box 2, lower box 3, in upper box 2, be provided with grading wheel 7, in lower box 3, be provided with feed pipe 6, in upper box 2, be also fixedly installed a discharging recoil air-casing 5, described discharging recoil air-casing 5 one end are in upper box 2 inside, the other end is in upper box 2 outsides, described discharging recoil air-casing 5 comprises outer tube 51, inner tube 52, left end ring 56 and right-hand member ring 57, outer tube 51 is enclosed within inner tube 52 outsides, between outer tube 51 and inner tube 52, form chuck 53, chuck 53 two ends, left and right are respectively with left end ring 56 and 57 sealings of right-hand member ring, on described left end ring 56, be also provided with an annular groove 561, on groove 561, be equipped with a circle aperture 562, described aperture 562 communication groove 561 and chuck 53, the bottom of grading wheel 7 is directly fixedly connected with the output of motor 1, the top of grading wheel 7 is embedded in groove 561, non-airtight connection between the top of grading wheel 7 and groove 561, this is because grading wheel 7 is tumblers, and the left end ring 56 and the whole discharging recoil air-casing 5 that are provided with groove 561 are static elements, between tumbler and static element, must leave gap, on described outer tube 51, be also provided with at least one air inlet 54, described air inlet 54 is in upper box 2 outsides.
Between upper box 2 and lower box 3, be also provided with a cyclone separator 4, the setting of cyclone separator 4.
On described cyclone separator 4, be provided with a pass air-valve 41, by adjustment, close the open degree of air-valve 41, can adjust the gas flow that enters grader.
On right-hand member ring 57, be also provided with screw 571, flange can be realized with discharging and being recoiled being connected of air-casing 5 by screw 571.
When work, the recoil right-hand member ring 57 use pipelines of air-casing 5 of discharging are connected to air-introduced machine, air-introduced machine forms negative pressure to grader inside, open motor 1, motor 1 drives grading wheel 7 to rotate, because the output of motor 1 is directly fixedly connected with grading wheel 7, attaching parts in the middle of having reduced are as belt pulley etc., therefore the High Rotation Speed of motor 1 has also driven the High Rotation Speed of grading wheel 7, after material enters from feed pipe 6, by air-flow, taken to grading wheel 7 around, 7 pairs of materials of grading wheel of High Rotation Speed sieve, the material that enters grading wheel 7 inside is the qualified material of classification, material enters into inner tube 52 inside from the top of grading wheel 7, and further by negative pressure, siphoned away, in this process, as shown in the arrow in Fig. 2, because inner tube 52 and grading wheel 7 inside are negative pressure, therefore extraneous air can enter into chuck 53 by air inlet 54, through the aperture 562 on groove 561, flow in the gap between grading wheel 7 tops and groove 561 again, the material of piling up in gap is washed away, played the effect that gas backwash is cleaned, this process continues to carry out in grader work always, that is to say, when grader is started working, gas backwash is just started working, therefore played the effect of original position cleaning, the material being present between grading wheel 7 and groove 561 can be continued to wash away, grader also can continuous firing, avoided shutting down cleaning and affected production efficiency.
