Abstract
The utility model discloses a low-speed rotary cylinder screen which comprises a casing body, a machine frame, a cylinder screen presenting horizontal arrangement, a screen bracket, a feed inlet port, a discharge port, a main shaft, a power device, and a driving device. The shaft axis of the main shaft can tilt towards the upper part of the feed inlet port. The included angle of the shaft axis and the horizontal plane is alpha 2 DGE-3 DGE. The cylinder screen is provided with a plurality of layers along radial direction, and the hole diameter of each layer of cylinder screen is different. The utility model has the advantages of simple structure and reliable work; the utility model can make use of lower rotation speed to provide the reliable working condition for a metering sensor of a mixing machine; thereby, the utility model can enhance the proportioning accuracy of the heat mineral aggregate with different graininess in the bituminous concrete and can enhance the construction quality in the process of the road construction.
Description
The utility model relates to a kind of equipment that utilizes screen cloth with the solid sizing screening, belongs to the material screening technical field, and it is particularly suitable for and the supporting use of bitumen concrete mixing machine.
In the road construction process,, varigrained hot mineral aggregate need be sieved the back and take by weighing use by different proportionings for guaranteeing the bitumen concrete quality.At present, the general hot mineral aggregate of bolting that uses in the production.Because the shaker vibration frequency is higher, the gage probe generation certain influence to the bitumen concrete mixing machine causes error in dipping big, influences the bitumen concrete quality.Simultaneously, the drum sieve of existing structure also is unsuitable for the screening of hot mineral aggregate, so need the new screening plant that addresses the above problem of development.
The utility model purpose is to provide a kind of low speed rotation drum sieve of simple in structure, reliable operation, utilize its lower rotary speed, for the gage probe of mixing machine provides reliable condition of work, thereby the degree of accuracy of the hot mineral mixture ratio of different grain size in the raising bitumen concrete lays the foundation for improving the road construction quality.
The objective of the invention is to be achieved through the following technical solutions:
A kind of low speed rotation drum sieve, comprise housing, the cylindric screen cloth of frame, screen cloth support, charging aperture, discharging opening, main shaft, power set and transmission device in the composition, the utility model is horizontal layout, cylindric screen cloth is fixed in screen cloth bracket supports on the main shaft by an end, end at drum sieve is provided with charging aperture, and the other end is provided with discharging opening.Main shaft in the drum sieve is connected with transmission device, and main shaft drives cylindric screen cloth around its axial line rotation, spindle axis alignment feed inlet end upper angled, with the angle α of horizontal plane be 2 °-3 °, the outside of cylindric screen cloth is provided with housing.Cylindric screen cloth of the present utility model radially is provided with multilayer, the aperture difference of each layer screen cloth.
Above-mentioned low speed rotation drum sieve describedly radially is divided into several sections with the cylindric screen cloth of one deck, the aperture difference of each section screen cloth;
Above-mentioned low speed rotation drum sieve, described cylindric screen cloth radially is provided with 2 layers.
The utlity model has advantage simple in structure, reliable operation, utilize its lower rotary speed, for the gage probe of mixing machine provides reliable condition of work, thus the degree of accuracy that improves the hot mineral mixture ratio of different grain size in the bitumen concrete, thus improve construction quality.
Below in conjunction with accompanying drawing, the utility model is described in further detail by embodiment.
Fig. 1 is that the utility model embodiment master looks cross-sectional view;
Fig. 2 is that the utility model embodiment overlooks cross-sectional view:
Fig. 3 is the A-A profile of Fig. 1.
Referring to accompanying drawing, present embodiment is the double-deck drum sieve structural representation of low speed rotation.By Fig. 1,2 as seen, the utility model is horizontal layout, main shaft 7 is connected with frame 2 by bearing and bearing block 16, the housing 1 of cylindric screen cloth 3 outsides is arranged on the frame 2, cylindric screen cloth 3 is supported by the screen cloth support 4 that an end is fixed on the main shaft 7, end at drum sieve is provided with charging aperture 5, and the other end is provided with discharging opening 6.Motor drives the interior main shaft 7 of drum sieve by belt pulley, reductor etc., main shaft 7 drives screen cloth support 4 and cylindric screen cloth 3 rotates with 14-22 rev/min rotary speed around its axial line, spindle axis alignment charging aperture 5 end upper angled, with the angle α of horizontal plane be 2.5 °.After the mineral aggregate of required screening enters the inner chamber of cylindric screen cloth, can progressively move down along with the rotation of rotary screen, enter feed bin by corresponding screen cloth.The cylindric screen cloth of present embodiment radially is provided with 2 layers, ground floor radially is divided into 4 sections: 3-1,3-2,3-3,3-4, its screen distance is followed successively by 10mm, 10mm, 20mm, 40mm, and the cylindric screen cloth of the second layer radially is divided into 2 sections: 3-5,3-6, its screen distance is followed successively by 5mm, 10mm.Every layer of screen distance of going up each section screen cloth is to require to determine according to the difference to the screening raw meal particle size.Below screen cloth 3-5,3-6 and 3-3,3-4, be provided with the feed bin 11,12,13,14 that is complementary with it successively.
Present embodiment low speed rotation drum sieve is mainly used in the required hot mineral aggregate of bitumen concrete mixing machine is sieved.During work, the hot mineral aggregate that hot elevator promotes enters the drum sieve inner chamber 9 of low speed rotation through charging aperture 5, and in the rotary course, the following hot mineral aggregate of 10mm enters inner chamber 10 by screen cloth 3-1, and the following hot mineral aggregate of 5mm passes through screen cloth 3-5, enters in the feed bin 11; Can not rotate with the rotational circle shaft screen by the hot mineral aggregate of screen cloth 3-5, enter in the feed bin 12 by screen cloth 3-6; Can not in rotational circle shaft screen rotation process, directly enter in the feed bin 13 by the mineral aggregate of screen cloth 3-6.Simultaneously, hot mineral aggregate that can not be by screen cloth 3-1,3-2 in the drum sieve inner chamber 9 moves down with the rotation of rotational circle shaft screen, and Φ 20mm is following, enters in the feed bin 13 by screen cloth 3-3.The following hot mineral aggregate of Φ 40mm enters in the feed bin 14 by screen cloth 3-4.Can not be defective mineral aggregate by the hot mineral aggregate of screen cloth 3-4, it be discharged by discharging opening along with the rotation of rotational circle shaft screen, promptly finishes screening, for the metering of bitumen concrete mixing machine provides reliable condition of work.
