Limestone crushing device
The utility model belongs to lime stone crushing equipment field, concretely relates to lime stone breaker.
In the production and processing of limestone, enterprises need to crush limestone into required particle size or powder according to the requirements of customers; the existing limestone crushing is generally carried out initial crushing firstly, large limestone raw materials are crushed into slightly small particles, then fine crushing is carried out through a crusher, a conveyor is required to be arranged in the middle for connection, the size of the fine crushed particles is not easy to control, and a large amount of dust overflows from a feeding port above the crusher in the crushing process to influence the working environment.
SUMMERY OF THE UTILITY MODEL
To defect and not enough problem among the prior art, the utility model provides a lime stone breaker can realize processing into granule building stones or powder of equidimension as required to the secondary crushing of lime stone raw materials, and it is convenient to adjust, and dust pollution is low in the processing.
The utility model provides a technical scheme that its technical problem adopted does:
the utility model provides a limestone crushing device, includes feeder hopper, the broken fill of one-level, the broken fill of second grade, powder play hopper and dust removal pipe, feeder hopper, the broken fill of one-level, the broken fill of second grade, powder play hopper from top to bottom link to each other in proper order, and the dust removal union coupling is between the broken fill top of one-level and powder play hopper, be equipped with jaw breaker in the broken fill of one-level, be equipped with drive roll and driven voller of broken usefulness in the broken fill of second grade, the drive roll is by motor drive, and the bearing frame of driven voller is installed and is slided the regulation on the slide rail, the broken fill below blanking department of second grade is equipped with the.
Furthermore, a suction fan is arranged on the dust removal pipe.
Furthermore, a bearing seat of the driven roller is connected with a speed reducing motor through a screw rod.
Furthermore, a slidable sealing door is arranged above the discharge port on the side surface of the secondary crushing hopper.
The utility model discloses following beneficial effect has: the dust removal pipe can absorb and collect dust generated in the feeding and crushing processes into the powder discharge hopper from the upper part, so that dust pollution is reduced, and stone loss is saved; the secondary crushing hopper can slide on the sliding rail through the driven roller to adjust a gap between the secondary crushing hopper and the driving roller, so that the size of the discharged particle size of secondary crushing is controlled; a powder sieve is arranged below the secondary crushing hopper, so that the crushed powder can be sorted into a powder discharging hopper, and the crushed small-particle stone is directly discharged from a discharging port at the right side; the sealing door is closed when only powder needs to be processed, and the material directly enters the powder discharge hopper at the bottom and is discharged.
Fig. 1 is a front view of the structure of the present invention.
The following describes in detail embodiments of the present invention with reference to the accompanying drawings.
As shown in the figure, a lime stone breaker, including feeder hopper 1, the broken 2, the second grade of fighting of one-level crushing, second grade crushing fight 3, powder play hopper 4 and dust removal pipe 5, feeder hopper 1, the broken 2, the broken 3, the powder play hopper 4 of fighting of one-level link to each other in proper order from top to bottom, and dust removal pipe 5 is connected between the broken 2 tops of fighting of one-level and powder play hopper 4, being equipped with jaw breaker in the broken 2 of fighting of one-level, being equipped with drive roll 11 and driven voller 12 of broken usefulness in the broken 3 of second grade, drive roll 11 is by motor drive, and the bearing frame of driven voller 12 is installed and is slided the regulation on the slide rail, the broken 3 below blanking departments of fighting of second grade are equipped.
Furthermore, a suction fan is arranged on the dust removal pipe 5.
Further, a bearing seat of the driven roller 12 is connected with a speed reducing motor 13 through a screw rod.
Furthermore, a slidable sealing door 231 is arranged above the discharge port 23 on the side surface of the secondary crushing hopper 3.
Specifically, drop into the limestone raw materials into feeder hopper 1, carry out preliminary breakage by the jaw breaker in the one-level broken hopper 2 earlier, break into the building stones of tiny particle with the raw materials of large particle, discharge into between two crushing rollers in the broken hopper 3 of second grade by the broken 2 bottom export 21 of one-level hopper, it is rotatory through motor drive roll 11, it carries out the secondary crushing to the building stones after the primary breaking to drive driven voller 12 rotation, the building stones that obtain required tiny particle after the breakage are discharged by below right side discharge gate 41, in the crushing process, the dust in the broken hopper 2 of one-level is collected through the powder play hopper 4 that dust removal pipe 5 absorption was discharged into the bottom, the powder that produces in the broken hopper 3 of second grade filters by powder sieve 31 and gets into powder play hopper 4, discharge by the 4 bottom discharge port of powder play hopper 4 at last.
When the secondary crushing hopper 3 works, the speed reduction motor 13 can drive the screw rod to transmit according to needs, the driven roller 12 is driven to slide on the slide rail, and the gap between the driven roller 12 and the driving roller 11 is adjusted to obtain stones with different crushing required particle sizes.
When only powder needs to be processed, the gap between the driving roller 11 and the driven roller 12 is adjusted to be minimum, the sealing door 42 on the discharge port 41 at the right side of the secondary crushing hopper 3 is closed, and the processed powder is directly discharged from the powder discharge port 4 at the bottom.
The foregoing shows and describes the general principles, essential features, and advantages of the invention. The present invention is not limited by the above embodiments, and the description in the above embodiments and the description is only for illustrating the principle of the present invention, and the present invention will have various changes and improvements without departing from the spirit and scope of the present invention, and these changes and improvements all fall into the scope of the present invention as claimed. The scope of the invention is defined by the appended claims and equivalents thereof.
