Abstract

The utility model discloses an energy-saving type dry cement kiln cooler clinker crushing device which is characterized by mainly comprising a sifting bed (1) and a meshed roller group (2), wherein the feeding end of the sifting bed (1) is butted with the discharging end of a grate (3); the discharging end of the sifting bed (1) is positioned on the upper part of the meshed roller group (2); the clinker enters the sifting bed (1) under the action of the push rod of the grate (3); the clinker of small size drops into a feeding channel (4) of a chain bucket machine on the lower part from a sieve pore on the sifting bed (1) and finally drops into the chain bucket machine; the clinker of large size drops in the meshed roller group (2) from the outlet end of the sifting bed (1); and the meshed roller group (2) extrudes and crushes the clinker of large size to the required size through the meshed extrusion, and the clinker drops into the feeding channel (4) of the chain bucket machine on the lower part and finally drops into the chain bucket machine to be conveyed to the next process. The device crushes the clinker by employing the low-noise meshed roller group, has the advantages of low noise, small wear and long average failure-free working time, and the electricity can be saved by over 50 percent compared with the traditional hammer type crusher.

Description

Energy-saving dry-process cement rotary kiln cooler grog breaker

Technical field

The utility model relates to a kind of cement equipment, and that uses in especially a kind of clinker cooling machine pulverizes the bulk grog so that the breaker of carrying, specifically a kind of energy-saving dry-process cement rotary kiln cooler grog breaker of brand new.

Background technology

As everyone knows, clinker is continuous large blocked structure through cooling machine cooling back major part, must process fragmentation just can enter bucket machine and send into next procedure and carry out abrasive dust processing, at the port of export of cooling machine some row's chain type breakers are installed normally for this reason, chain impacts grog repeatedly under the driving of driving mechanism, the subject matter that this device exists, the one, noise is big, and the 2nd, energy consumption is big, and the idle stroke of chain is big, waste energy, the 3rd, described space is big, and the 4th, crushing effect is uncontrollable, and is undesirable, must be broken again through hammer mill, there is the rotating speed height in hammer mill, noise is big, airborne dust is big, wearing and tearing are big, the power consumption height.This still there is not good solution.

Summary of the invention

The purpose of this utility model is big at energy consumption in the grog fragmentation of existing chamotte cooler, noise, floor space is big, the problem of crushing effect difference designs a kind of noiselessness, low, little, the tangible energy-saving dry-process cement rotary kiln cooler grog breaker of power saving effect of wearing and tearing of rotating speed.

The technical solution of the utility model is:

A kind of energy-saving dry-process cement rotary kiln cooler grog breaker, it is characterized in that it mainly comprises sifting bed 1 and to nibbling roller group 2, the feed end of described sifting bed 1 docks with the discharge end of the bed 3 of combing, the discharge end of sifting bed 1 is positioned at nibbling the top of roller group 2, grog enters sifting bed 1 under the effect of bed 3 push rods of combing, the bucket machine feeding-passage 4 that the sieve aperture of undersized grog from sifting bed 1 falls into the bottom finally falls into bucket machine, large-sized grog falls into nibbling roller group 2 from the port of export of sifting bed 1, to nibble roller group 2 by to nibble extruding with large scale grog attrition crushing to required size and fall into the bucket machine feeding-passage 4 of bottom, also finally fall into bucket machine and deliver to next procedure.

Describedly have four rolls to nibbling roller group 2, roll is driven by drive unit and rotates, two one group on described roll, and the direction of rotation of two rolls in every group all is equipped with on each roll for the pointed tooth rake post to nibbling.

The line of motion speed of described pointed tooth rake post be 2-6 rice/minute.

Described to being connected with cooling water in the roll of nibbling roller group 2.

The beneficial effects of the utility model:

The utility model by adopt noise little carry out fragmentation to nibbling running roller, have the advantage that noise is low, wearing and tearing are little, the mean time between failures is long, compare and can economize on electricity more than 50% with traditional hammer mill.

The utility model is simple in structure, and manufacturing, installation, maintenance are conveniently.

Description of drawings

Fig. 1 is structural representation of the present utility model.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further described.

As shown in Figure 1.

A kind of energy-saving dry-process cement rotary kiln cooler grog breaker, it mainly comprises sifting bed 1 and to nibbling roller group 2, sifting bed 1 can be made into fixed bed, also can be made into the structure of vibrated bed, also can adopt regular vibration beating to be blocked to prevent sieve aperture.The feed end of described sifting bed 1 docks with the discharge end of the bed 3 of combing, the discharge end of sifting bed 1 is positioned at nibbling the top of roller group 2, grog enters sifting bed 1 under the effect of bed 3 push rods of combing, the sieve aperture of undersized grog from sifting bed 1 falls into passage earlier and enters the bucket machine feeding-passage 4 that connects with blanking channel again, finally fall into bucket machine, large-sized grog falls into nibbling roller group 2 from the port of export of sifting bed 1, to nibble roller group 2 by to nibble extruding with large scale grog attrition crushing to required size and fall into the bucket machine passage 4 of bottom, also finally fall into bucket machine and deliver to next procedure, in order to realize the guide effect, to nibbling blanking channel preferred design sloping or the step-like structure of roller group 2 bottoms, so that to nibbling the bucket machine feeding-passage 4 that the grog of rake after broken falls into the bottom smoothly, as shown in Figure 1.Describedly have four rolls to nibbling roller group 2, roll is driven by the planetary gear speed reducing driving device and rotates, two one group on described roll, the direction of rotation of two rolls in every group, all be equipped with on each roll for the pointed tooth rake post to nibbling, the line of motion speed of described pointed tooth rake post be 2-6 rice/minute, described to being connected with cooling water in the roll of nibbling roller group 2.

The utility model utilizes pointed tooth rake principle, uses in groups, and fines leaks down in the middle of two tooth harrows, and coarse fodder is constantly harrowed by the pointed tooth of two relative motions rake post and cut and crack to fines.The movement velocity 2-6 i/min of pointed tooth rake, but water flowing cooling in the middle of the axle.Crack the bulk grog with pointed tooth rake, every roll is driven by the planetary gear reductor, and noiselessness, rotating speed is low, wearing and tearing are little, power saving saves 1/2(with respect to hammer mill).

The utility model does not relate to partly all, and the prior art that maybe can adopt same as the prior art is realized.
