Description
Technical field
The utility model relates to a kind of novel screening machine that industries such as grain, water conservancy, building materials, coal are carried out material screening that is widely used in.
Background technology
Domestic existing sieving machine mostly is oscillatory type greatly at present, form by screen box, support, vibrator, shock-absorbing spring, screen cloth etc., its operation principle is, produce exciting force by vibrator, whole screen box vibration, material enters screen cloth, makes the granule in the material see through screen cloth to greatest extent in the vibration, reaches the requirement of screening.Its medium-height trestle supports screen box by shock-absorbing spring, and screen cloth is fixed on the screen box by certain angle, and the power that vibrator produces is delivered on the screen cloth by screen box, realizes whole vibrosieve process.Screen cloth is the key of whole screening process, also is the core component of whole sieving machine, mainly contains forms such as following mesh grid, chevron shaped casting screen cloth, comb-tooth-type, excellent screen cloth now.Mesh grid uses steel wire to weave into by certain pore size, and it is little to exist setting angle, and material is by horizontal movement on screen cloth, and screening efficiency is low, easily network blocking, and the life-span is short, is not suitable for the screening of big batch materials, progressively is eliminated.Chevron shaped casting screen cloth is sieve aperture to be cast as " people " word or " eight " font, and wearability slightly improves, but that major defect is a percent opening is low, and easily hole clipping can't be cleared up, and screening efficiency is low.The comb-tooth-type screen cloth also belongs to the casting screen cloth, and structure is that several rows of little dentation overlap joint forms, and shortcoming is easy plug-hole, is not easy cleaning, and along with the increasing of wearing and tearing, it is big that sieve aperture becomes, the screening effect instability.The rod screen technology is from external introduction, and characteristics are that sieve aperture is open, and the subject matter of existence is easily broken rod, and screen life-span is low, can not be used for the screening of high-temperature material, the easy hole clipping of screening small particles material.Existing sieving machine the critical particle hole clipping occurs when screen cloth, all can't clear up immediately, particularly material water ratio, when viscosity is high, screen cloth stops up serious, screening efficiency is low.Many in addition employing mode of vibrations are sieved, and noise is big, big to foundation failure power, and the service life of screen box, screen cloth is short.
