Description
Technical field
The utility model relates to a kind of ore reduction equipment, is that a kind of dry method quartz sand is produced unit specifically, can improve the production efficiency of frosted.
Background technology
At present, dry method quartz sand is produced unit, is mainly become by skin grinder, bolter, rough classification sieve, subfractionation screen banks.When broken, the quartz sand ore is fed intake by skin grinder one end axial feed inlet, behind the preliminary ball mill crushing of skin grinder, takes by skin grinder other end discharging opening that the semi-finished product material is sent into the rough classification sieve, the subfractionation sieve is counted step-sizing by the order of setting and is classification finished product material out of.Because the backing ring at skin grinder two ends is the open circles oblique crank Z and radially install with the support roller of shape when cooperating, because skin grinder is movably arranged on and plays support and spacing on the support roller, so have certain axial displacement when rotating, will cause the limit of gnawing of the spacing shoulder in support roller both sides to wear and tear like this, influence the service life of support roller.In addition, the mill tube inboard that is positioned at the skin grinder discharge end has three and is 120 ° of vertically arranged band flitch that distribute, and is used to take out of the semi-finished product material.Owing to produce centrifugal force during the skin grinder rotary work, therefore supply with to divide about subordinate's screening installation can only take 75% out of and select materials through the semi-finished product material of skin grinder fragmentation, like this, promptly influence output, directly bring power consumption and processing cost height again.In addition, a part of fine granularity material after the preliminary fragmentation of skin grinder enters elevator and continues to be fed into screening installation; And another part coarsegrain material is directly discharged by bolter, and by artificially collecting processing, it is broken once more to send into skin grinder again, so repeatedly.Will increase labor intensity of operating personnel like this.For this reason, seeking a kind of frosted unit of specialty, enhance productivity, guarantee energy-conservation and improve service life, is that the problem that will solve is badly in need of in the present technique field.
Summary of the invention
In view of above-mentioned present situation, the utility model provides a kind of dry method quartz sand to produce unit, makes its semi-finished product strip that improves the skin grinder fragmentation go out rate and service life, cuts down finished cost.
The inventor through improving test, has finished the utility model according to above-mentioned design on this basis.
Specific implementation technical solution of the present utility model is: dry method quartz sand is produced unit, comprises the skin grinder with drive unit, and the skin grinder discharging opening connects bolter, is positioned at the bolter lower end and has an elevator; This elevator discharging opening sieves feeding mouth corresponding to rough classification; This rough classification sieve is connected with a subfractionation sieve feeding mouth; Described bolter, elevator, first classifying screen, subfractionation screening are not connected with dust arrester by pipeline; Wherein, the backing ring at described skin grinder two ends is an arch cylinder shaft body; The backing ring of this arch cylinder shaft body is installed with the support roller of its concave arc body that matches and is cooperated; The mill tube inboard that is positioned at the skin grinder discharge end is distributed with the band flitch that forms an angle with direction of rotation; At described bolter and skin grinder bottom the feed back belt feeder that has along extending the skin grinder feeding end is installed.When this skin grinder is broken, utilize the backing ring of the arch cylinder shaft body on the skin grinder to cooperate with the support roller installation of its concave arc body that matches, effectively limited the axial float of skin grinder mill tube, the stationarity that maintenance rotatablely moves has reduced the wearing and tearing between backing ring and support roller.Simultaneously, skin grinder has improved half-finished band material rate by having the band flitch of certain angle, has reduced processing cost.Be used to be provided with the feed back belt feeder, saved the big problem of manually-operated labour intensity.
According to such scheme, the angle of related band flitch is less than 180 °, and its band flitch is 120 ° or crossing distribution.
In this programme, mentioned feed back belt feeder, the endless belt that comprises the live-roller of setting and install on it; On the live-roller of a described wherein side, connect drive unit.
In the utility model, mentioned dust arrester is connected with the deduster of outdoor setting; This deduster is connected to any sack cleaner or cyclone dust collectors by connecting air-introduced machine.
In sum, the dry method quartz sand that the utility model provides is produced unit, cooperate with the support roller installation of its concave arc body that matches by the arch circle backing ring that utilizes the skin grinder two ends to have, can avoid the axial float of skin grinder mill tube, keep the stationarity that rotatablely moves and reduced wearing and tearing to each other, improved service life.Simultaneously, the mill tube inboard of having improved the skin grinder discharge end has the band flitch that forms an angle with direction of rotation, make the skin grinder fragmentation after, can improve half-finished band material rate and reach 95%, improved production efficiency, reduced processing cost.In addition, owing to be provided with the feed back belt feeder, saved the labour intensity of artificial returning charge.
