Abstract

The invention discloses an energy-saving dry-method cement kiln cooler clinker crushing device which is characterized by mainly comprising a screening bed (1) and an engaging roller group (2), wherein a feeding end of the screening bed (1) is butted with a discharging end of a grate (3); a discharging end of the screening bed (1) is positioned on the upper part of the engaging roller group (2); clinkers enter the screening bed (1) under the action of a push rod of the grate (3); small-size clinkers drop into a lower chain bucket machine feeding channel (4) from sieve pores in the screening bed (1) and finally drop into a chain bucket machine; large-size clinkers drop into the engaging roller group (2) from an outlet end of the screening bed (1); and the large-size clinkers are extruded and crushed to the required size by the engaging roller group (2) through engaging extrusion, drop into the lower chain bucket machine feeding channel (4), and finally drop into the chain bucket machine so as to be sent into the next process. The device has the advantages that: the clinkers are crushed by low-noise engaging rollers, so that the device is low in noise, slight in wear, averagely zero in fault and long in operating time; and compared with the conventional hammer crushers, the clinker crushing device can save the electricity by over 50 percent.

Description

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

Technical field

The present invention relates to a kind of cement equipment, 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 and could get into bucket machine and send into next procedure and carry out abrasive dust and process; At the port of export of cooling machine plurality of rows chain type breaker is installed normally, chain impacts grog repeatedly under the driving of driving mechanism for this reason, 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; Undesirable, must be broken once more through hammer mill, there is the rotating speed height in hammer mill, noise is big, airborne dust is big, wearing and tearing are big, power consumption is high.This still there is not good solution.

Summary of the invention

The objective of the invention is to energy consumption in the grog fragmentation of existing chamotte cooler, noise big; Floor space is big; The problem of crushing effect difference designs a kind of noiselessness, rotating speed is low, wearing and tearing are little, the tangible energy-saving dry-process cement rotary kiln cooler grog breaker of power saving effect.

Technical scheme of the present invention is:

A kind of energy-saving dry-process cement rotary kiln cooler grog breaker; It is characterized in that it is mainly by sifting bed 1 with 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 gets into 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, and large-sized grog falls into nibbling roller group 2 from the port of export of sifting bed 1; To nibbling roller group 2, also finally fall into bucket machine and deliver to next procedure through to nibbling extruding with large scale grog attrition crushing to required size and fall into the bucket machine feeding-passage 4 of bottom.

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 the pointed tooth rake post that is used for nibbling on each roll.

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.

Beneficial effect of the present invention:

The present invention through 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 present invention is simple in structure, and manufacturing, installation, maintenance are conveniently.

Description of drawings

Fig. 1 is a structural representation of the present invention.

The specific embodiment

Below in conjunction with accompanying drawing and embodiment the present invention is further described.

As shown in Figure 1.

A kind of energy-saving dry-process cement rotary kiln cooler grog breaker, mainly by sifting bed 1 with to nibbling roller group 2, sifting bed 1 can be made into fixed bed, also can be made into the structure of vibrated bed for it, 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, and grog gets into sifting bed 1 under the effect of bed 3 push rods of combing, and the sieve aperture of undersized grog from sifting bed 1 falls into passage earlier and get into 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 nibbling roller group 2 through to nibbling extruding with large scale grog attrition crushing to required size and fall into the bucket machine passage 4 of bottom, also finally falls into bucket machine and delivers to next procedure; In order to realize the guide effect; To nibbling the 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 is equipped with the pointed tooth rake post that is used for nibbling on each roll; 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 present invention 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 saving 1/2 (with respect to hammer mill).

The present invention does not relate to all identical with the prior art prior art that maybe can adopt of part and realizes.
