Abstract

The utility model discloses a dust-free vibrating screen which comprises a vibrating-screen top plate and a vibrating-screen bottom plate. One end of the vibrating-screen top plate is movably connected with the vibrating-screen bottom plate through a pin shaft, a cavity is formed between the vibrating-screen top plate and the vibrating-screen bottom plate, a vibrating screen body is mounted in the cavity, a vibrating motor is mounted at the lower end of the vibrating body, one end of each of the vibrating-screen top plate and the vibrating-screen bottom plate is provided with an opening, two screen cloth, namely the first screen cloth and the second screen cloth, are arranged inside the vibrating-screen top plate, and both the first screen cloth and the second screen cloth are of hollow structures. The dust-free vibrating screen is mainly used for screening materials with larger dust; since the screen cloth is of the hollow structures with upper end surfaces sealed, when the first screen cloth is vibrated, the materials are only vibrated vertically inside the first screen cloth, the materials smaller in diameter fall into the second screen cloth via vibration, and the materials subjected to vibrating are low in dust capacity. The dust-free vibrating screen is simple in structure, convenient to demount, low in dust capacity and flexible to use.

Description

A kind of dustless vibrating screen
Technical field
The utility model relates to a kind of dustless vibrating screen.
Background technology
During work, two motor synchronous backward rotations make vibrator produce reverse exciting force, force sieve nest to drive screen cloth to do lengthwise movement, make the material on it be subject to exciting force and the range of periodically dishing out forward, thereby complete material screening operation.Suitable stone pit riddled sand building stones, also can do grading for industries such as coal separation, ore dressing, building materials, electric power and chemical industry.Vibratory sieve working portion maintains static, and by material, along working face, slides and material is sieved.Static grizzly be in ore dressing plant, apply more a kind of, be generally used for coarse crushing or in prescreening before broken.It is simple in structure, easily manufactured.Do not consume power, can directly ore be discharged on compass screen surface.Major defect is that productivity ratio is low, screening efficiency is low, generally only has 50-60%.
But, process the object that some Dust Capacities are large, when vibration screening, often dust is very large, causes working environment variation, and traditional vibratory sieve, if want to increase vibration intensity, size that can only regulation voltage electric current, has wasted resource.

Technical problem to be solved in the utility model be to provide a kind of dust little, simple in structure, screen clear, convenient disassembly, dustless vibrating screen that use cost is low.
The utility model is achieved through the following technical solutions: a kind of dustless vibrating screen, involving vibrations sieve top board and vibratory sieve base plate, described vibratory sieve top board is " L " type, between vibratory sieve top board one end and vibratory sieve base plate, by a bearing pin, be flexibly connected, between described vibratory sieve top board and vibratory sieve base plate, form a cavity, one vibration sieve nest is installed in this cavity, the lower end of this vibration sieve nest is provided with a vibrating motor, described vibration sieve nest is arranged on vibratory sieve top board lower surface, described vibratory sieve top board and vibratory sieve base plate one end opening, between opening, be provided with an above cushion block, this cushion block bottom offsets with vibratory sieve base plate, the upper end of cushion block is provided with a spring, the other end of this spring is provided with one " L " type contiguous block, in described vibratory sieve top board, be provided with two screen clothes, be respectively the first screen cloth and the second screen cloth, described the first screen cloth and the second screen cloth are hollow-core construction, centre is cavity structure, the upper surface, right side of the first screen cloth offers a charging aperture, the bottom of the bottom of the first screen cloth and the second screen cloth offers the filter bores of different-diameter size, the charging aperture upper end of described the first screen cloth is provided with a feed hopper, feed hopper is over against charging aperture, the left end of described the first screen cloth and the second screen cloth is provided with discharging opening.
As preferred technical scheme, described contiguous block is magnetic contiguous block, and inhale mutually with vibratory sieve top board upper end, and inhale mutually with spring lower end.
As preferred technical scheme, the discharging opening place of described the first screen cloth is provided with an arc-shaped convex.
As preferred technical scheme, described the first screen cloth and the second screen cloth are left low right high incline structure, and the upper surface of described the first screen cloth is enclosed construction, and the upper surface of described the second screen cloth is hatch frame.
The beneficial effects of the utility model are: the utility model mainly screens the material that some dust are larger, when vibration screening, because screen cloth is hollow structure, upper surface is enclosed construction, the first screen cloth is when vibration, material is only in the inner up-down vibration of the first screen cloth, and the material of minor diameter falls in the second screen cloth through vibration, and the material of screened mistake Dust Capacity is little, the utility model is simple in structure, convenient disassembly, Dust Capacity is little, uses flexibly.
