Weak point in above-mentioned background technology: selection by winnowing that both cannot realization mechanism sand, also cannot effectively eliminate the dust in Machine-made Sand.

Utility model content

Purpose of design: avoid the weak point in background technology, design one can either adopt wind-force to realize different-grain diameter Machine-made Sand and select, and can meet again the Machine-made Sand wind-force air classifier multistage high wind cabin body that in Machine-made Sand, dust is escaped.

Design: in order to realize above-mentioned purpose of design.1, the design of plane mechanism sand wind-force air classifier multistage high wind cabin body, is one of technical characterictic of the present utility model.The object of doing is like this: the entirety that Machine-made Sand wind-force air classifier cabin body is comprised of five cabins that are associated, is respectively one section of high wind cabin, two sections of high wind cabins, three Duan Zhong plenum chamber, four sections of material cabins and five sections of material cabin compositions.(1) one section of high wind cabin and two sections of high wind cabins are because the quality of Machine-made Sand lays particular stress on, throughput is bigger than normal, therefore be in its end face and be provided with outside main air port the also both sides at its boiling-house and be provided with secondary air port to supplement air quantity, the intake in main air port and secondary air port is controlled by the control of PLC controller.Wherein the main air port in one section of high wind cabin and two secondary air ports are used a main air blower separately to wind; A secondary blower fan of two sections of common uses in high wind cabins and three Duan Zhong plenum chamber is to wind; Three Duan Zhong plenum chamber due to the quantity of its feeding with need the quality of its Machine-made Sand blowing all to reduce, therefore in three Duan Zhong plenum chamber, be only provided with main air port, the air quantity that the source of its air quantity produces for accessory fan.The powerful wind of giving of the main air port of charging aperture lower end, is blown into adjacent boiling-house Machine-made Sand with wind-force, and in the both sides of boiling-house, is provided with secondary air port to supplement air quantity, make Machine-made Sand in boiling-house constantly by from bottom to top and the wind-force of both sides blow.Oarse-grained Machine-made Sand is because the quality of self exceedes blowing of wind-force during this time, and therefore the Machine-made Sand of this rank is fallen into one section of discharging opening below high wind cabin and enters next link.The Machine-made Sand of the little rank up blowing through boiling-house is admitted to the transition sub-material mouth between one section of high wind cabin and two sections of high wind bins, the deduster inlet scoops that dust is in five sections of material cabin tops are during this time sucked away, quality is greater than dust and the fine particle that is less than other machine-made sands drops into five sections of material and collects in inclined chutes, is constantly sent into five sections of storehouses.Remaining Machine-made Sand is fallen into due to the factor of sole mass in the feed space in two sections of high wind cabins.(2) the feed space lower end main air port in two sections of high wind cabins constantly provides corresponding air quantity, the Machine-made Sand of this section is constantly blown into the boiling-house in two sections of high wind cabins, and be provided with secondary air port in the boiling-house both sides in two sections of high wind cabins, to assist main air port to wind, two sections of Machine-made Sands in high wind cabin are constantly up blowed by air quantity from bottom to top, quality Machine-made Sand bigger than normal during this time, due to the former of own wt thereby be trapped in the blanking oral area in two sections of high wind cabins, and constantly sent into next link.Dust part in the Machine-made Sand up being blowed in two sections of high wind cabin boiling-houses continues to be siphoned away by five sections of material cabin dedusters suitable for reading, wherein five sections of material cabin material also fall in second five sections material collection inclined chutes, and five sections of material collecting in inclined chute along with five sections of storehouses material of upper level fall into five sections of storehouses together.This part Machine-made Sand that quality is greater than five sections of storehouse material is admitted in three sections of storehouses.(3) enter three sections of Machine-made Sands in storehouse are continued to enter three Duan Zhong plenum chamber boiling-house by the air quantity that main air port was blown into of bottom, the Machine-made Sand that quality is partially light is blown in four sections of storehouses, and this part Machine-made Sand that quality lays particular stress on naturally just falls into the bottom of three Duan Zhong plenum chamber and is admitted to next link.(4) the Machine-made Sand that enters four sections of storehouses also naturally falls into bottom, storehouse, is admitted to next link.The Machine-made Sand separating from the rank in section cabin, one section of cabin to four is admitted to corresponding holding vessel through the pipeline of lower end, cabin separately respectively.2, the design that the wearing plate that has different size is all spliced in the inside of Machine-made Sand wind-force air classifier cabin body, be technical characterictic of the present utility model this two.The object of doing is like this: because Machine-made Sand is gone through evil to the wearing and tearing of its inwall in the process of selection by winnowing very much, splice the wearing plate of different size on its wall, be convenient to the later stage to be convenient for changing wearing plate according to abrasion condition.3, the design of one section of cabin, two sections of cabins, three sections of cabin feed openings, feed cavity, boiling cavity is three of this bright technical characterictic.The object of doing is like this: feed opening can directly directly screen the Machine-made Sand that is greater than wind-force; And the design of feed cavity, boiling cavity, make Machine-made Sand in feed cavity in the effect of wind-force seethe from lower to upper, and in the process of seething, both reached the screening of Machine-made Sand particle diameter, separated again dust, realized the object of dustless Machine-made Sand.At body top, Machine-made Sand wind-force air classifier cabin, be all provided with service hatch, with convenient for maintaining.

Technical scheme: a kind of Machine-made Sand wind-force air classifier multistage high wind cabin body, by multistage high wind cabin, formed, the structure in every section of high wind cabin is identical, the upper surface in its high wind cabin has charging aperture, has that main air port, the left and right sides have secondary air port, high wind discharging opening is opened in lower end above, middle and upper part, chamber, high wind cabin is vertically provided with separate space plate and high wind cabin is divided into feed cavity and boiling cavity, and the upper end, high wind cabin that is positioned at body top, multistage high wind cabin has charging aperture.

The utility model compared with background technology, the one, in the body of Machine-made Sand wind-force air classifier cabin, the design in high wind cabin, has realized the object to different-grain diameter Machine-made Sand selection by winnowing; The 2nd, the design that the wearing plate that has different size is all spliced in the inside of Machine-made Sand wind-force air classifier cabin body, is convenient to the later stage to be convenient for changing wearing plate according to abrasion condition; The 3rd, in the body top service hatch setting of Machine-made Sand wind-force air classifier cabin, just maintenance.
