Abstract
The utility model provides an anti-blocking grid plate which comprises a coarse screen plate and a fine screen plate. The coarse screen plate is combined with the fine screen plate, the fine screen plate is fixed to the rear of the coarse screen plate, and grid holes are respectively arranged on the coarse screen plate and the fine screen plate. The anti-blocking grid plate has the advantages that when grinding media, slag and cement are filled into the grid holes of the coarse screen plate during production running of a mill, the cement is fed into a next bin via the fine screen plate, and the grinding media and the slag automatically fall from grid gaps of the coarse screen plate and return to a front bin, so that the grinding media can be prevented from flowing into the next bin, and the cement can pass through the fine screen plate without being affected; the coarse screen plate also protects the fine screen plate against being damaged due to impact of the grinding media, effective sectional areas of the grid gaps of the grid plate of a partition are guaranteed, the anti-blocking grid plate is abrasion-resistant and practical, the shortcoming of blockage of an existing grid plate is overcome, and the grinding efficiency of the mill is improved; and the anti-blocking grid plate is not only applicable to one-pass grinding, but also is applicable to circle grinding.
Description
Technical field
The new shape of this practicality relates to a kind of cement mill double-layered isolating plate grate plate, the anti-clogging grate plate in especially a kind of grinding machine.
Background technology
Double-layered isolating plate is the vitals of grinding machine, mainly is to play to cut apart abrasive body, prevents that big material from scurrying material flow in discharge end and the control mill.But the grate of double-layered isolating plate grate plate seam is to the performance important influence of partition panel effect, the requirement that must satisfy control material flow, favourable ventilation and prevent from stopping up, and wear-resisting and do not change performance.In order to guarantee that grate plate grate is sewn on the effective cross sectional area in the grinding machine actual motion, people constantly explore.The form in grate hole is divided into " V " shape, different " V " shape and several big classes of " V " shape of falling traditionally.For the ease of manufacturing and easy to maintenance, China has worked out the 3rd batch " cement machinery accessory standard atlas ", and the shape and size in grinding machine, partition panel grate plate grate hole have been done unified regulation.
Yet when the grinding machine actual motion, existing these several grate seams, the scum when abrasive body may wear to a certain degree and material piece, always some just in time is fit to the granularity of this size, is stuck in grate and sews on, and causes the grate plate to stop up.These external two kinds of grate plate difficulty of processing are also bigger.Particularly in recent years in cement pulverizing course a large amount of equipment such as roll squeezers that use as pre-grinding equipment, mill feed material size reduces greatly, the size of the interior abrasive body of mill is corresponding dwindling also, so just cause the grate seam of traditional grate plate very easily to stop up, particularly even more serious in the forging storehouse, make and the appearance of mill ventilation deficiency, full mill, paste ball problems such as (forgings) greatly reduce mill efficiency.
The utility model content
The purpose of this utility model is to provide a kind of simple in structure at the problems referred to above, is difficult for producing the anti-clogging grate plate in material and abrasive body obstruction grate hole.
To achieve these goals, technical solution adopted in the utility model is: described anti-clogging grate plate is combined by scalping plate and thin sieve plate, and thin sieve plate is fixed on the scalping postlaminar part; Be respectively arranged with the grate hole on described scalping plate and the thin sieve plate.
The minimum widith in described scalping plate grate hole is the maximum sphere diameter of abrasive body or forging length 2 to 3 times.Distance between the length in grate hole and grate hole is according to the size of grate plate shape and guarantee that its wearability adjusts.
Described thin sieve plate grate hole width is 0.3 to 0.5 times of minimum abrasive body diameter, is formed by punching of the steel plate.
Described scalping plate grate hole be shaped as straight hole shape or radiation or " V " font.
Described scalping plate grate hole thereon be distributed as concentric circles or polygon or radiation or oblique line shape or splayed.
The utility model is in grinding machine production run process, and when abrasive body and material slag when entering scalping plate grate hole with cement, cement enters next storehouse by thin sieve plate, and abrasive body and material slag come off automatically from scalping plate grate seam and turn back to preceding storehouse.So both can prevent that abrasive body from flowing into next storehouse, not influence passing through of cement again.And the scalping plate has been protected thin sieve plate not to be subjected to the impact of abrasive body and has been damaged, and has guaranteed the effective cross sectional area of partition panel grate plate grate seam, has realized wear-resisting practicality, has overcome the drawback that the grate plate stops up again, thereby has improved the mill efficiency of grinding machine.

The specific embodiment
By reference to the accompanying drawings, specific embodiment of the utility model is described.
As shown in Figure 1, 2, 3: described anti-clogging grate plate is combined by scalping plate 1 and thin sieve plate 2, and thin sieve plate 2 is fixed on scalping plate 1 rear portion; Be respectively arranged with the grate hole on described scalping plate 1 and the thin sieve plate 2.
It is radiation that described scalping plate 1 grate hole is arranged; The width B in grate hole is 60mm according to 3 times of designs of abrasive body diameter 20mm.The grate hole be shaped as straight hole shape.Distance L between the length C in grate hole and grate hole is according to the size of mill diameter, grate plate shape and guarantees that its wearability adjusts, and present embodiment grate hole length C is 300mm, and the distance L between the grate hole is 80mm.The thin sieve plate 2 grate hole width D that are close to thereafter are that 3mm, length E are 30mm, are formed by punching of the steel plate.The material of grinding can flow into next storehouse smoothly with regard to having realized preventing the obstruction of grate plate like this, and it is smooth and easy to ventilate, and has improved the mill efficiency of grinding machine.Described thin sieve plate grate hole width is 2mm, and sieve seam length 20mm is formed by punching of the steel plate.
