Abstract
The utility model relates to a spiro type screener, wherein screen nets are circular arc-shaped and are fixed on the middle lower portion in a case whose hollow cavity is divided into an upper screening cavity and a lower material outlet cavity, the upper portion of the screen nets is provided with a spiro rotary drum which is a barrel body structure, and the surface is further provided with a convex ring steel rope which is arranged in spiro shape and is close to the screen nets. The two ends of the spiro rotary drum are connected with a rotary shaft, the rotary shaft on the one end is connected with a deceleration motor through a drive chain wheel, the top portion of one end of the case is provided with a material inlet, and the lower portion on the other end is provided with a waste material outlet. The utility model can directly screen wet material, and nonqualified material which is screened can be directly broken, which reduces procedures, improves manufacturing efficiency, and saves energy consumption. And the convex ring steel rope which encircles the outer wall of the rotary drum and are arrayed in spiro shape approaches a fixed screen and moves in swiveling motion, and forcedly and repeatedly turns and rubs the material which is selected. The utility model can aim at needle-shapes material and selects, which overcomes the technical problem that the current needle-shaped material is difficult to be screened.
Description
Technical field
The utility model relates to a kind of screening installation, is specifically related to a kind of to particle and with the volution formula screening machine of fine wet stock sizing screening.
Background technology
At present, in the Wood-based Panel Production processing industry of wooden flake board (flakeboard) or other crops straw, circular oscillating riddle, square sieve, reciprocating vibration sieve or the swinging drum sieve of rocking are mostly adopted in the screening for preparing of wood shavings and particle, these screening installations all are to screen by the vibration of screen cloth, only be fit to the screening of dried material, and for water content higher moist material and needle-like material (bamboo shaving, bagasse, cotton stalk etc.), stick in easily on the screen cloth, be difficult to realize screening by technological requirement.Utilize non-wood material to produce in the melting process of wood-based plate, just moisture content mostly requires the scope at 25%-35%, the particle form that processes is better relatively, in this operation as not, the bulk particle is separated reprocessing, must increase difficulty to drying, particularly to needle-like (band fine) material such as bamboo shaving (particle), bagasse, cotton stalk particle etc., the difficulty of the dry forward and backward sizing screening of existing screening installation all is bigger.So need to solve the screening problem of wet particle and needle-like (band is fine) material at present, to satisfy the requirement of relevant artificial board production technology, enhance productivity, reduce energy consumption, reduce production costs.The still unresolved at present the problems referred to above of one of ordinary skill in the art.
The utility model content
At the prior art above shortcomings, the purpose of this utility model provides a kind of volution formula screening machine that is used for wet mince material and the screening of needle-like (band is fine) material.
The purpose of this utility model is achieved in that a kind of volution formula screening machine, comprise casing and screen cloth, it is characterized in that: screen cloth is that circular arc is fixed on the middle below in the casing, the cavity of housing is divided into screening chamber, top and discharging chamber, bottom, the top of screen cloth is provided with the volution rotary drum, the volution rotary drum is a tube structure, and it is approaching that its surface also is provided with the bulge loop steel cable and the screen cloth of helix shape; The two ends of volution rotary drum connect rotating shaft, and the rotating shaft of an end is connected with reducing motor by drive sprocket; The top of casing one end is provided with charging aperture, and other end bottom is provided with waste outlet.
Described bulge loop steel cable ring is a wire line thimble around forming, and it is around outer wall of rotary drum and arrange twist, around the ring helical arrangement in the outer wall of rotary drum.
Steel cable is the elastic wire rope, has wear-resisting and gentle (bullet) property of steel.
Compared to existing technology, the utlity model has following advantage:
1, can directly screen wet stock, the defective material that filters out can directly carry out broken again, has reduced operation, has improved production efficiency, and has saved energy consumption.
2, by the bulge loop steel cable ring of also arranging twist around the outer wall of rotary drum, do gyration, turn over stranding by force again by sorting material near fixed grit; Can screen the needle-like material, overcome prior art spicule material screen and selected the difficult technologies problem.
3, simple in structure, the stable performance, with low cost of this machine, it is high-quality good that the screening gradation is imitated.
Description of drawings
Fig. 1 is the structural representation of the utility model volution formula screening machine.
Fig. 2 is the A-A cutaway view of Fig. 1.
Among the figure, 1, bulge loop steel cable ring 2, screen cloth 3, screen bed base 4, rotating shaft (and bearing block) 5, volution rotary drum 6, reducing motor 7, drive chain and sprocket wheel 8, casing 8.1, screening chamber 8.2, discharging chamber 9, access door 10, charging aperture 11, coarse fodder (defective material) outlet
The specific embodiment
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
Referring to Fig. 1, a kind of volution formula screening machine of the present utility model, comprise casing 8 and screen cloth 2, screen cloth 2 is fixed on the screen bed base 3 for circular arc, and screen bed base 3 is fixed on the below in the casing 8, and the cavity of housing 8 is divided into screening chamber 8.1, top and discharging chamber, bottom 8.2, and the top of screen cloth 2 is provided with volution rotary drum 5, volution rotary drum 5 is a tube structure, and its surface also is provided with the bulge loop steel cable ring 1 of helix shape and approaching with screen cloth 2 (revolution); The two ends of volution rotary drum 5 connect rotating shafts (with bearing block) 4 and are connected with reducing motor 6 with chain 7 by drive sprocket, are rotated by drive sprocket and chain 7 and rotating shaft 4 drive volution rotary drums 5 by reducing motor 6; The top of casing 8 one ends is provided with charging aperture 10, and other end bottom is provided with thick material outlet 11.
Described bulge loop steel cable ring 1 forms around structure for wire line thimble, has wear-resisting and gentle (bullet) property of steel.
Described casing 8 sidewalls are provided with access door 9, in order to maintenance volution formula screening machine or replacing screen cloth and cleaning screen cloth.
The utility model is when work, at first connect power supply, start volution formula screening machine, material to be screened is imported from charging aperture 10, along with the rotation of volution rotary drum 5, turn under stranding, the extruding at the bulge loop of bulge loop steel cable ring 1, qualified material is forced down screen cloth 2, and the Elastic Steel becket bridle 1 of helical arrangement can produce the promotion of rolling backward to material when rotated simultaneously, so underproof material can be pushed out coarse fodder outlet 11 along with the rotation of volution rotary drum 5.The qualified material of screening gained enters drying, and defective material is pulverized once more and screened.
