Abstract

The utility model relates to a piano wire screen used for sizing different ores, such as dolomite, limestone, iron ore, etc. The utility model is composed of a frame, a piano wire supporting board and a steel wire vertical stripe net. The steel wire of the steel wire vertical stripe net is penetrated in a circular hole on the piano wire supporting board; the piano wire supporting board is fixed on the frame. Via adjusting the spacing of each steel wire on the steel wire vertical stripe net, the ore with different grains can be sieved. The piano wire screen has the advantages of long service life, high sieving efficiency, convenient maintenance, etc. The utility model can be popularized in the metallurgy mine.

Description

Piano wire screen

The utility model provides a kind of piano wire screen, and it is used for the grade screening of breaking ores such as dolomite, lime stone and iron ore, belongs to the BO7B1/OO class.

In prior art, be used for industry ore grade screenings such as metallurgical mine, construction material wire gauze sieve, the steel plate stamped sieves etc. of adopting more, they can sieve the ore of various grades, but weak point is easy putty, and secondly the especially easier obstruction of wet feed is easy to wear, change very inconvenient, so screening efficiency is not high, labor strength is big, is the problem that needs solve.

The purpose of this utility model is that a kind of making of development is easy, changes convenient, as to improve screening efficiency novel vibrating screen---piano wire screen.

Solution of the present utility model is: with the framework of angle steel or channel-section steel or other metal materials making piano wire screen, this framework can be foursquare or rectangular earlier, and its size can be fixed according to technological process and designing requirement.Any relative both sides at framework are made into the piano wire screen gripper shoe with band steel or other section bars, and the spacing of string gripper shoe is adjustable.The circular hole that on these string gripper shoes, has several spacings to equate.The string of piano wire screen passes from these circular holes, and the aperture of circular hole and spacing also will decide according to the granularity of sieving.On the other relative both sides of framework, also have the fixing hole that several spacings equate, in these fixing holes, use screw, nut and briquetting plate and sheet rubber the string of piano wire screen---fixation with steel wire is on framework.In order to make framework indeformable at work, the fixed head of also can burn-oning.After the plate face of piano wire screen is made, do a frame again and can use.

Below in conjunction with accompanying drawing the utility model is done more detailed explanation.

Fig. 1 is a schematic diagram of the present utility model.

Fig. 2 is that the B-B of Fig. 1 is to cutaway view.

Fig. 3 is the partial view of Fig. 2.

Simultaneously, Fig. 1 is a specification digest accompanying drawing of the present utility model

As shown in the figure, the framework of piano wire screen is made of metal materials such as channel-section steel or angle steel, is fixed with the string gripper shoe 3 of equal in length on its any relative edge 1 or 2, and their quantity and spacing are adjustable.Have on string gripper shoe 3 that several spacings equate, the identical circular hole in aperture, the aperture of these circular holes and spacing also are adjustable, and the string of piano wire screen---steel wire 7 passes from these circular holes.Be equipped with on the other relative both sides 4 or 5 of framework that several spacings equate, the identical fixing hole 6 in aperture, these fixing holes can be circular, also can be other shapes.Pass the circular hole of the string of piano wire screen---steel wire 7 on string gripper shoe 3, constituted row string---steel wire vertical bar net in good order, use screw 8, nut 9 again, briquetting plate 10 and sheet rubber 11 are with string---and steel wire 7 is fastened in the circular hole 6 on the edge 4 or 5 of framework.So just constituted the sieve plate of piano wire screen.After sieve plate is made, make a limit thick stick frame again and just formed piano wire screen.

Use piano wire screen to sieve the ore of size fractionated such as dolomite, lime stone and iron ore, can improve 5～10 times of screening efficiencies, improved operating rate greatly.

After using after a while, if find the string concentrated wear,, unclamp screw, nut etc. as long as take out framework, extract the steel wire of wearing and tearing out, change new steel wire and just can continue to use.
