Abstract

The utility model discloses a vibrating screen which comprises a rack, a screen box, at least two layers of screen cloth and a vibrating device for providing a power source for the screen cloth, wherein the screen box is arranged on the rack; the screen cloth is arranged in the screen box and connected with the vibrating device; a feed port and at least two dust discharging pipes are arranged at the top of the screen box; a discharge port is formed in the bottom of the screen box; the aperture of the screen cloth of the upper layer is greater than that of the screen cloth of the lower layer; an oversize outlet is formed in the sidewall of the screen box and in a position corresponding to the screen cloth of each layer; the screen cloth is arranged in parallel in the screen box; a dust remover is connected to one end of each dust discharging pipe. The vibrating screen is compact and reasonable in structure and convenient to operate and maintain; a plurality of layers of screen cloth are arranged, so that the screening efficiency is improved to a great extent, the power consumption is reduced, and the production cost of an enterprise is greatly lowered; a plurality of dust discharging pipes are arranged at the top of the screen box, so that dust can be uniformly discharged from the vibrating screen, and the screening accuracy of the vibrating screen is improved to a certain extent.

Description

A kind of vibratory sieve

Technical field

The utility model relates to sieving machine field, specifically a kind of vibratory sieve.

Background technology

In hydroxide filler aluminium oxide dry powder production process, the finished product of aluminium hydroxide dry powder need to be packed respectively according to certain particle diameter.In industry, customary way is in finishing room at present, aluminium hydroxide dry powder is sprayed in the vibratory sieve of different mesh sizes, at the discharging opening of vibratory sieve, collect the aluminium hydroxide dry powder of different-grain diameter, but this method need to be purchased many vibratory sieves, every vibratory sieve all will be equipped with corresponding vibrating device simultaneously, and separation costs is high, and screening efficiency is low, floor space is large, and screening precision is also difficult to reach ideal effect.

Utility model content

For addressing the above problem, the utility model provides a kind of novel vibratory sieve, its equipment forms from common vibratory sieve transformation, simple in structure, combines the feature of aluminium hydroxide dry powder production technology, by the screen cloth of different pore size is set in screen box, solved common vibratory sieve screening efficiency in particle diameter separation process low, separation costs is high, and the technical barrier such as screening precision is poor, and then improved production efficiency, can effectively reduce the production cost of enterprise.

The utility model is for solving the problems of the technologies described above, the technical scheme providing is: a kind of vibratory sieve, comprise frame, screen box, screen cloth and for the vibrating device of power source is provided to screen cloth, screen box is arranged in frame, screen cloth is arranged in screen box and is connected with vibrating device, the top of screen box is provided with charging aperture and dust flue, discharging opening is arranged on the bottom of screen box, described screen cloth is at least two-layer, and the aperture of upper strata screen cloth is greater than the aperture of lower screen, on the sidewall of screen box, corresponding every one deck screen cloth is equipped with oversize outlet.

Described screen cloth is installed in parallel in screen box.

Described dust flue is at least two, in one end of dust flue, is connected with deduster.

Beneficial effect:

1. vibratory sieve of the present utility model, by multilayer screen cloth is set in screen box, has improved screening efficiency largely, has reduced the production cost of enterprise; The design of the multiple dust outlet tubes in screen box top, makes to vibrate the screening precision of sifting out dirt more evenly and having improved to a certain extent vibratory sieve.

2. Structure of Vibrating Screen compact and reasonable of the present utility model, convenient operating maintenance, and it is little to take up room, and operating efficiency is high, and manufacture craft is simple, and cost of manufacture and use cost are cheap, and power energy consumption is little, and disposal ability is strong, is conducive to processing business enterprise expand and uses.

Reference numeral

Fig. 1 is structural representation of the present utility model;

Mark in figure: 1, charging aperture, 2, dust outlet tube, 3, screen cloth, 4, vibrating device, 5, screen box, 6, oversize outlet, 7, discharging opening, 8, frame.

The specific embodiment

Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described:

A kind of vibratory sieve, comprise frame 8, screen box 5, screen cloth 3 and for the vibrating device 4 of power source is provided to screen cloth 3, screen box 5 is arranged in frame 8, screen cloth 3 is arranged in screen box 5 and is connected with vibrating device 4, the top of screen box 5 is provided with charging aperture 1 and dust flue 2, and discharging opening 7 is arranged on the bottom of screen box 5, and described screen cloth 3 is at least two-layer, and the aperture of upper strata screen cloth 3 is greater than the aperture of lower screen 3, on the sidewall of screen box 5, corresponding every one deck screen cloth 3 is equipped with oversize outlet 6.

Described screen cloth 3 is installed in parallel in screen box 5.

Described dust flue 2 is at least two, in one end of dust flue 2, is connected with deduster.

The setting of multilayer screen cloth, makes a vibratory sieve interior dry powder finished product that can isolate multiple different-grain diameter at one time, has improved largely screening efficiency, and compact conformation is reasonable, take up room little, manufacture craft is simple, power energy consumption is little, greatly reduces the production cost of enterprise; The design of the multiple dust outlet tubes in screen box top, makes to vibrate the screening precision of sifting out dirt more evenly and having improved to a certain extent vibratory sieve.
