Abstract
The utility model relates to a hammer type wet coal crusher used for preparing a coal assay sample. The crusher is provided with a vibrating sieve plate and a rubber strip curtain of anti cementation material. The phenomenon of clogging can not generate when wet coal samples are fed into the crusher. Crushed products conform to the requirement of established granularity, so a wet coal sample drying process is omitted; the time of sample preparation is shorten; crushing production quality is ensured.
Description
The utility model relates to the wet coal disintegrating machine of a kind of hammer used when preparing the coal analytical sample.
Though the used disintegrating machine of preparation coal analytical sample has the numerous species type now, their common drawback is can not broken wet coal.For example, general jaw crusher, double-roll crusher and Clothoid type disintegrating machine etc., just feeding mouth can be blocked, make it and can't remain in operation in case surpass 8% as the moisture of broken pan feeding.General hammer mill also is like this, can be unrestricted though do not add the broken pan feeding moisture of sieve grate, and the granularity of crushed product does not reach requirement; If add sieve grate, pan feeding moisture reaches at 10% o'clock, also can the sieve aperture on feeding mouth and sieve grate be blocked.Therefore, each factories and mines all must or dry sample drying before full-page proof or other analytical sample are produced in preparation, and this just needs long time, has both influenced production, has postponed quoting the time of analytical test result again.
Through consulting relevant technologies document both domestic and external and data, do not find broken to contain the disintegrating machine of the wet coal sample of any moisture as yet.
The purpose of this utility model, provide a kind of can broken wet coal or the disintegrating machine of other shot shape wet stock.No matter how high the moisture of broken pan feeding is, must not dry or dry, and can directly feed the utility model---the hammer coal disintegrating machine that wets, and just it can be crushed to the granularity of requirement, thereby simplify the sample preparation operation, shortened the sample preparation time.
Below in conjunction with accompanying drawing 1 explanation concrete structure of the present utility model and embodiment.
The utility model is made up of lower casing (3), upper casing (4), armature spindle (5), disk (6), tup (8), vibrator (10), adhesive tape curtain (11), vertical sieve tray (12), semicircle sieve plate (13) and receiving hopper main parts size such as (14).In the machine chamber that the upper casing (4) and the rectangle lower casing (3) of arched top constituted, level is being installed armature spindle (5).4 disks (6) are installed on the armature spindle, disc circumference uniform 4 little axles (7), every little axle is gone up string and is adorned 3 tups (8), can rotate around little axle separately.The rotor that armature spindle (5), disk (6), little axle (7) and tup (8) are formed is driven by motor (2), with 1500~3000 rev/mins rotating speed rotation.During rotor rotation, the tup (8) that string is contained on the little axle (7) is just got rid of directly, also with rotor rotation.Two ends are housed below the rotor are fixed on semicircle sieve plate (13) on the casing.Up to feeding mouth (9), vertical sieve tray (12) is housed along the tangential direction of semicircle sieve plate one end, the wet coal sample that is smashed by tup (8) just is splashed on the vertical sieve tray.Because the horizontal section of the vertical screen utmost point is ] shape, can wrap basically and stop the whole coal samples that are splashed on the sieve plate.The upper end of vertical sieve tray (12) is connecting vibrator (10), and it can drive vertical sieve tray and shake up and down.The semicircle sieve plate (13) that is connected with vertical sieve tray also can be shaken up and down with vertical sieve tray.Sieve aperture on the vertical sieve tray (12) is the microscler sieve aperture that two ends are semicircle, and the width in hole is 1.5~2 times of the crushed product size upper limit, and the major diameter in hole is slightly less than the width of sieve plate; Also have the microscler sieve aperture that two ends are semicircle on the semicircle sieve plate (13), the width in hole is 2~2.5 times of the crushed product size upper limit, and the major diameter in hole also is slightly less than the sieve plate width.The major diameter direction of sieve aperture is parallel with armature spindle (5) on two kinds of sieve plates.Between vertical sieve tray (12) and upper and lower casing (4), (3) sidewall, also install the adhesive tape curtain (11) that the rubber strip solid matter of a predetermined number forms.The upper end of each adhesive tape of adhesive tape curtain is fixed on the upper casing (4), and the lower end hangs down into naturally near bottom of shell, and each adhesive tape close proximity overlaps mutually, but does not link to each other mutually.Upper and lower casing fuses, and is installed on the base (1) of hollow, and the right-hand part of base is being laid receiving hopper (14); Motor (2) is then installed in the left side of base.
Practice shows that the utility model both had been convenient to implement, and achieved noticeable achievement again.
Because in the wet coal disintegrating machine of hammer vertical sieve tray and the semicircle sieve plate that constantly shakes up and down is housed, the crushed product of high-moisture can not be bonded on the sieve plate.Because of each adhesive tape curtain closely overlaps, the crushed product of sieve plate shake in addition, saturating sieve can not see through curtain yet and adhere on the enclosure wall again.Like this, broken pan feeding moisture is just unrestricted, and company's moisture can both be crushed to the satisfactory product of granularity up to 16~18% band water pan feeding, makes sample no longer carry out drying, has simplified the sample preparation operation, has shortened the sample preparation time.
Fig. 1 is the utility model---the structure of the wet coal disintegrating machine of hammer is always schemed.
Embodiment:
With the wet coal sample of auxiliary breaking, evenly feed the wet coal disintegrating machine of hammer with suitable speed.Fall into and revolve at a high speed the rotor that encloses and form coal sample in the space, smashed and diffusing splashing by tup (8).The main direction spatter of loosing is the tangential direction of the tup (8) that the smashes coal sample circular trace of rotating.Smashing the coal sample that flashes just in time has vertical sieve tray (12) to accept.Be splashed to the broken coal sample on the sieve plate, granularity is mistake less than the just saturating sieve of sieve aperture, and granularity is greater than sieve aperture and drop on the coal sample at non-mesh place, shakes up and down because of vertical sieve tray (12) is strong to be shed on the semicircle sieve plate (13).Because of distance between tup (8) and semicircle sieve plate is very little, the coal sample that is shed on the semicircle sieve plate is subjected to hammering once more, because of depositing coal in the casing nowhere, can only all sieve thoroughly after being pulverized.Wet coal sample behind the saturating sieve, though particularly not only wet but also sticking from the coal sample of the saturating sieve of vertical sieve tray, they drop on and are beaten to such an extent that disorderly tremble to touch and incessantly wave but on the mutual disjunct adhesive tape curtain (11) just landing downwards by the sample of screening coal thoroughly of sputter.Like this, wet coal sample can not be bonded on the sieve plate, can not be bonded on the adhesive tape curtain, more can not be bonded on the enclosure wall by curtain, thereby guarantee the wet coal disintegrating machine operate as normal of hammer.Go up wet coal sample landing and saturating sieve from adhesive tape curtain (11), all fall in the receiving hopper (14).This has just finished the shattering process of wet coal sample.Because of crushed product all is to discharge by the sieve aperture of regulation, its granularity conforms to quality requirements fully.
If treat that the moisture of broken coal sample is lower, with the wet coal crusher in crushing of hammer, product is surmised more and is conformed to quality requirements.
