Abstract
The utility model discloses an inner filtering filter type vacuum filter. The technical scheme is that equipment comprises a machine driven system, a cylinder outer wall, a filter cloth supporting plate, a pressing groove, filter cloth and a group of clamping devices, and the inner filtering filter type vacuum filter is characterized in that each clamping device is composed of a pressing rod, a filter cloth press plate arranged on the end part of the upper part of the pressing rod, an adjusting gasket, a press plate and bolts, and each clamping device is fixed on the cylinder outer wall through the bolts. The inner filtering type vacuum filter provided by the utility model has the beneficial effects that the filter cloth clamping device of the inner filtering filter type vacuum filter of the scheme adopts a filtering cloth compacting method utilizing the batten pressing rod for compacting and the bolts for fixing, and completely eradicates phenomena such as falling and damage of filtering cloth, and damage of the pressure groove, therefore, recycling of battens is realized, production disconnection is avoided, and the inner filtering filter type vacuum filter has the advantages that the structure is simple, the maintenance is convenient, the property is reliable, the cost is low, and the use is convenient.
Description
Technical field
The utility model relates to the powder metallurgy production technical field, and a kind of inner leaching vacuum filtering machine of iron ore concentrate is separated, is used for filtering in the water ore deposit of the metal ore pulp when relating in particular in powder metallurgical production technique the preparation iron powder.
Background technology
At present, in Powder Metallurgy Industry, for the water ore deposit separation of metal ore pulp, usually adopt GN20 type inner leaching vacuum filtering machine, be used for the water ore deposit separation of comparatively loose metal ore pulp, be applicable to filter iron ore concentrate.GN20 type inner leaching vacuum filtering machine utilizes positive and negative blower system, filters by filter cloth.Existing technology is that filter cloth compress to adopt the rope made of hemp to compress (as shown in Figure 2), and the rope made of hemp is pressed into filter cloth in indent, but through the use of certain hour, easily causes the grooving distortion or because of the rope made of hemp pine phenomenon such as cause that filter cloth comes off excessively, has affected normally carrying out of producing.Have a significant impact for the continuity of producing.The deficiency that prior art that Here it is exists.
Summary of the invention
The purpose of this utility model is to improve the shortcoming that exists in prior art, and a kind of inner leaching vacuum filtering machine that a kind of volume is little, simple in structure, can guarantee continuous production is provided.The technical scheme that adopts is: include machine driven system, cylinder body outer wall, filter cloth supporting plate, indent, filter cloth and one group of hold down gag, it is characterized in that: described hold down gag by depression bar, be arranged on described depression bar top end filter cloth pressing plate, adjust pad, pressing plate, bolt and form, and by described bolted on described cylinder body outer wall.
Technical characterictic of the present utility model also has: the T-shaped shape of described depression bar cross section, and insert in described indent, and one group of through hole is set on described depression bar, described bolt is set in through hole.The material selection pine of depression bar utilizes the characteristics of timber, makes filter cloth fixing more firm.
Technical characterictic of the present utility model also has: described pressing plate is arranged on the both sides of described depression bar, and compresses by described end filter cloth pressing plate.
Operation principle: filter cloth and air chamber rotate with the rotation of cylindrical shell, and air chamber is divided into 20 isolated areas, the outside independent pressure of supplying with respectively.The air chamber of filtering area and drying zone remains the negative pressure of 30kpa under the effect of back-blowing system, along with the water in slip is pumped through filter cloth and filter cloth supporting plate under negative pressure, the slip of cylinder body bottom forms gradually uniform muffin and is attached on filter cloth.The air chamber of discharge zone and filter cloth cleaning area remains the normal pressure of 60-80kpa, when muffin arrives discharge zone, under the effect of gravity and positive blower system, muffin drops on discharge device, filter cloth is rotated further, and removes the accumulated powder on filter cloth when cleaning area, comes and goes and repeats.
The beneficial effects of the utility model are:
1) pressing device for filter cloth of this programme adopts the batten depression bar to compress, and the fixing filter cloth of bolt compresses mode, has stopped filter cloth fully and has come off, damages, the phenomenons such as indent damage.
2) realize the recycling of batten, reduced maintenance cost, avoided producing the disconnection in this link.3) simple in structure, easy to maintenance, dependable performance has advantage with low cost, easy-to-use.
Description of drawings
Accompanying drawing 1 is the working region division of GN-20 type inner leaching vacuum filtering machine cylindrical shell.Accompanying drawing 2 is prior art pressing device for filter cloth structural representations, and accompanying drawing 3 is the utility model structural representations, and accompanying drawing 4 is front views of depression bar, accompanying drawing 5 is left views of accompanying drawing 4, and wherein, I is the filter cloth cleaning area, II is discharge zone, and III is drying zone, and IV is filtering area, 1 ' be filter cloth, 2 ' be the filter cloth supporting plate, 3 ' be the rope made of hemp, 4 ' be air chamber, 5 ' be cylinder body outer wall, the 1st, cylinder body outer wall, the 2nd, filter cloth supporting plate, the 3rd, filter cloth, the 4th, end filter cloth pressing plate, the 5th, depression bar, the 6th, bolt, the 7th, adjust pad, the 8th, pressing plate, the 9th, indent, the 10th, air chamber.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is specifically described.
A kind of inner leaching vacuum filtering machine in the utility model, include machine driven system, cylinder body outer wall 1, filter cloth supporting plate 2, indent 9, filter cloth 3 and one group of hold down gag, be provided with altogether 20 groups of hold down gags, hold down gag is formed, and is fastened on cylinder body outer wall 1 by bolt 6 by depression bar 5, the end filter cloth pressing plate 4 that is arranged on depression bar 5 tops, adjustment pad 7, pressing plate 8, bolt 6.The depression bar 5 T-shaped shapes of cross section are inserted in indent 9, and one group of through hole are set on depression bar 5, and bolt 6 is set in through hole.Pressing plate 8 is arranged on the both sides of depression bar 5, and compresses by end filter cloth pressing plate 4.
Concrete grammar: T-shape depression bar 5 is embedded the rearmounted pressing plate 8 of indent 9, adjusts pad 7 in depression bar 5 tops, end filter cloth pressing plate 4 is placed in the position parallel with depression bar 5, then with bolt 6, pressing plate 8, adjustment pad 7, depression bar 5 are anchored on cylinder body outer wall 1, and end filter cloth pressing plate 4 is killed.Filter cloth 3 is pressed on filter cloth supporting plate 2.
