Abstract
The invention discloses an environmental protection down vibration three shaft elliptical vibrating screen which comprises a monolayer or double layer elliptical vibrating screen; three sets of vibrators are arranged on the lower part of a straining box and is connected with a synchronizer by a universal joint; the synchronizer is connected with two electric motors by a pin coupling; the upper part of an inlet orifice is provided with a distributor; a tensioner is fixedly arranged between the lower part of a lid and the straining box; a length of sealed sylphon bellows is arranged between the distributor and the inlet orifice, and between a discharge hole and a connecting feeding receptacle; the lid is fixed on the straining box; the tensioner is arranged between the lid and the straining box. A rubber sheet is changed to a lengthen of the sealed sylphon bellows in the invention, which improves the sealing performance when the vibrating screen works, and the dust does not come out to pollute the environment, thus meeting the requirement of being more environmental.
Description
Technical field:
The present invention relates to screening, particularly a kind of simple in structure, reliable environmental-protecting type lower vibration type three shaft elliptic vibrative screen of sealing property.
Background technology:
Traditional elliptically vibrating screen is to do vibration source by one group or two groups of vibrators, makes screen box produce the elliptical vibration track, and its sealing and dustproof system is provided with fixing seal closure on screen box top.The large-scale elliptically vibrating screen of the list of this structure (two) layer, because the dither of screen box during work, between the faying face of elastic rubber slab and screen box, be prone to the slit, cause dust spill and leakage in the screen box to come out, pollute working environment, its vibrator of traditional in addition vibratory sieve is located at screen box top, and center of gravity height, transmission platform easily produce nuisance vibration.
Summary of the invention:
The purpose of this invention is to provide a kind of simple in structure, reliable environmental-protecting type lower vibration type three shaft elliptic vibrative screen of sealing property.
Technical solution of the present invention is finished as follows, it includes an individual layer or double-layer oval-shaped vibratory sieve, it is characterized in that: three groups of vibrators are installed in the screen box bottom, three groups of vibrators connect with synchronized by Hooks coupling universal coupling, synchronized is connected with two motors through pin coupler, be provided with distributing device on charging aperture top, cover between bottom and the screen box and be fixedly connected with tensioning apparatus at sieve, between distributing device and the charging aperture and be connected with the bellows of one section sealing between discharging opening and the receiving hopper respectively.On screen box, be fixed with the sieve lid, between sieve lid and the screen box tensioning apparatus be installed.
The present invention changes rubber slab into one section bellows, the sealing property when having improved work effectively, and dust can not fly out contaminated environment, has reached environmental protection requirement more.
Description of drawings:
Fig. 1 is the structural representation of a kind of double-layer oval-shaped vibratory sieve of the present invention, and Fig. 2 is the left view of Fig. 1, and Fig. 3 is the A-A cutaway view of Fig. 1, and Fig. 4 is a fundamental diagram of the present invention.
The specific embodiment:
Describe embodiment in detail in conjunction with above accompanying drawing, the present invention is improvements over the prior art, it includes an individual layer or double-layer oval-shaped vibratory sieve, be inlaid with three groups of vibrator 4 vibrators connects with synchronized 6 by Hooks coupling universal coupling 5 in the bottom of screen box 3, synchronized is driven through pin coupler 8 by two motors 7, make three groups of vibrator F1, F2, F3 respectively by arrow indicated direction ω rotation among Fig. 4, make screen box 3 make elliptical vibration.Main improvements are that three shaft vibration devices are embedded on the side plate of screen box bottom, fixed by high-strength bolt, change traditional rubber slab that is located between distributing device 1 and the charging aperture 10 into one section bellows 2 simultaneously, still change the elastic rubber slab between discharging opening and the receiving hopper 9 into one section bellows 2, sieve covers 13 and is fixed on the screen box by pressing plate 11, and fixes by tensioning apparatus 12 tensionings.
Claims (2)
