Abstract
The utility model relates to a negative rake-angle multilevel-folded-face linear vibrating screen, and belongs to the technical field of screening machinery. The technical scheme includes that the linear vibrating screen comprises a screening box and a vibrating motor, the screening box comprises a screening frame and a screen, the screening frame is connected around the screen and is basically connected with a screening machine through a damping spring, the vibrating motor is arranged on the upper portion of the screening frame, the screen is separated into two parts along the material delivering direction, one part connected with a feeding port of the screening box is a positive-rake-angle screen, and another part connected with a discharge port of the screening box is folded into a multilevel negative rake-angle screen. A single-level negative-rake-angle screen of the traditional negative linear vibrating screen is replaced by the multilevel negative-rake-angle screen, so that the height of the screening frame and even the screening machine are greatly reduced without affecting functions of the screening machine, material waste is avoided, mass of vibration is reduced, energy consumption of vibrating generator set is reduced.
Description
Technical field
The utility model relates to a kind of negative incidence linear vibrating screen (hereinafter to be referred as screen(ing) machine) that is applicable to screening, classification, dehydration and the desliming processing of coal, quartz sand and various mineral, belongs to the screening plant technical field.
Background technology
At present, the compass screen surface (screen cloth) that is used for the negative incidence linear vibrating screen of dehydration on the market generally is divided into two sections, one section of feeding end (is conducive to material to inclination angle that discharge end moves for positive rake, this section compass screen surface is higher near an end of screen box feeding mouth), one section of discharge end (stops material to inclination angle that discharge end moves for negative incidence, this section compass screen surface is higher near an end of screen box discharging opening), two sections compass screen surfaces are to being connected into the V-type compass screen surface.Its shortcoming is that discharge end can exceed much than feeding end when screen length is big, and the screen(ing) machine height is increased, and screen frame side plate area increases, and mass of vibration increases, and then causes the waste of material and the increase of screen(ing) machine work energy consumption.
The utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, the multistage folding face of a kind of negative incidence linear vibrating screen is provided, and to reduce the consumption of screen(ing) machine material, reduces the work energy consumption of screen(ing) machine.
Problem described in the utility model realizes with following technical proposals:
The multistage folding face of a kind of negative incidence linear vibrating screen, comprise screen box and vibrating motor in the formation, described screen box comprises screen frame and the screen cloth that is connected with screen frame all around, described screen frame is connected with the screen(ing) machine basis by damping spring, its top is vibrating motor fixedly, described screen cloth is divided into two sections along the mass transport direction, and one section that joins with the screen box feeding mouth is the positive rake screen cloth, and one section that joins with the screen box discharging opening is converted into multistage negative incidence screen cloth.
The multistage folding face of above-mentioned negative incidence linear vibrating screen, the discharge end height unanimity of the working face of negative incidence screen clothes at different levels.
The multistage folding face of above-mentioned negative incidence linear vibrating screen, described vibrating motor arranges two groups, and their symmetries are installed on two side plates of screen frame, and mutual corresponding vibrating motor connects by synchronous connecting axle on the screen frame biside plate.
The utility model changes the single-stage negative incidence screen cloth of conventional negative inclination angle linear vibrating screen into multistage negative incidence screen cloth, under the prerequisite that does not influence the screen(ing) machine function, greatly reduce the height of screen frame and even whole screen(ing) machine, avoided the waste of material, also reduce mass of vibration simultaneously, reduced the energy consumption of vibrating motor group.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further specified.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is vertical view of the present utility model.
Each label is among the figure: 1, screen frame, 2, synchronous connecting axle, 3, vibrating motor, 4, the negative incidence screen cloth, 5, damping spring, 6, the positive rake screen cloth.
The specific embodiment
Referring to Fig. 1, Fig. 2, the utility model comprises screen frame 1, synchronous connecting axle 2, vibrating motor 3, damping spring 5 and screen cloth, and wherein, screen cloth is formed by connecting by positive rake screen cloth 6 and multistage negative incidence screen cloth 4.The discharge end height unanimity of the working face of negative incidence screen clothes 4 at different levels.
Screen frame 1 is connected with the screen(ing) machine basis by damping spring 5, two groups of vibrating motor 3 symmetries are mounted on the side plate on screen frame 1 both sides, the straight-line oscillation direction of vibrating motor 3 and the working face of negative incidence screen cloth 4 form certain angle, vibrating motor 3 corresponding on screen frame 1 biside plate connects by synchronous connecting axle 2, make two groups of vibrating motors 3 when work, keep run-in synchronism, screen frame 1 two ends are respectively arranged with cloth and material collecting device (not drawing among the figure), negative incidence screen clothes 4 at different levels and positive rake screen cloth 6 are all spliced rigidity screen cloth, the sieve aperture form can be rectangle or slit-aperture type, screen material can adopt polyurethane or metal material, after multistage negative incidence screen cloth 4 and positive rake screen cloth 6 interconnect, periphery is tightly connected with screen frame 1 again, and multistage negative incidence screen cloth 4 forms a plurality of stages along the mass transport direction.
When the utility model carries out the material dewatering operation, the centrifugal force that the eccentric block rotation of vibrating motor 3 produces just in time acts on the center line of screen frame 1 side plate vertical section with joint efforts, do not bear moment of flexure during side plate work, vibrating motor 3 drives screen frame 1 and does straight-line oscillation, material on the negative incidence screen cloth 4 is constantly got up to be fed forward by throwing along the straight-line oscillation direction, will drop on the next stage negative incidence screen cloth 4 when moving to the front end of one-level negative incidence screen cloth 4, under the effect of the gravity of water own, water meeting spontaneous current on the negative incidence screen cloth 4 is to the opposite direction of mass transport, when arriving the extreme lower position of negative incidence screen cloth 4, leak to compass screen surface by sieve aperture, thereby accelerated the dewatering speed of material, improved the water separation capability of screen(ing) machine.That this screen(ing) machine has is simple in structure, whole height is low, the side plate area is little, total quality is light, reliability is high, advantage such as energy-efficient.
