Description

The multichannel hammer mill

Technical field

The utility model relates to a kind of breaker, is specially a kind of multichannel hammer mill.

Background technology

Known, the critical piece of hammer mill is that assembly is impacted in the revolution that has number row tup, the motor drives revolution is impacted assembly and is rotated at a high speed at the housing inner chamber of sealing, material enters in the housing from the top material inlet, be subjected to the strike of the hammer of high-speed motion, impact, shear, abrasive action and fragmentation, impact the assembly bottom in revolution and be provided with the grate bar, fine fraction less than adjacent grate interspace in the comminuting matter is discharged by the grate bar, on the grate bar, continue to be subjected to the strike and the grinding of hammer greater than the coarse fraction detention of adjacent grate interspace, thereby finish material grinding, have simple in structure, the ratio of reduction is big, characteristics such as production efficiency height are applicable to building stones, sandstone, the fragmentation of materials such as gangue.But the upper and lower casing of existing hammer mill is a closed, if in equipment power failure suddenly in service, material can be full of whole crusher chamber, stop up the grate bar, this moment, people can only slowly clear material from charging aperture, because the inner space is narrow and small, not only waste time and energy, and cleaning is unclean; In addition, when the equipment operation long period, when enclosure interior drive disk assembly and grate bar need repairing, when especially changing the grate bar, because the closed structure of existing disintegrating machine can only be taken upper and lower casing apart, just can operate, same existence is wasted time and energy, the problem of inconvenient maintenance.

For addressing the above problem, this patent applicant discloses a kind of hammer mill in the patent No. is 200720138244.1 patent document, main design is to offer through hole and the dodge gate that is used for pull grate bar on lower house, need not to dismantle under the situation of upper and lower casing, just can carry out replacing, the maintenance of grate bar, the cleaning of stopping up material.But also there is following problem in actual use in the disintegrating machine of this kind structure, material is when the material inlet of upper shell falls into disintegrating machine, because initial material particular diameter skewness, inevitably can be mingled with the fine particle stage material of some particle diameters in the overwhelming majority coarse fraction material less than adjacent grate interspace, these fine particle stage materials are not with carrying out fragmentation again, can directly drop down onto discharging opening through the grate interspace, but because all grate bars all are installed in the lower house, fine particle stage material is in the strike that also can be subjected to the hammer of high-speed motion in the material inlet dropping process along with the coarse fraction material together, impact, shear, abrasive action, last together through being positioned at the grate interspace of lower house, drop down onto discharging opening, like this, if equipment long-time running, increased the equipment tup virtually, the loss of parts such as grate bar, increased the extra power output of equipment, reduced output, and the coarse fraction material after those fine particle stage materials and the fragmentation can fall into the housing below together, easily cause the accumulation of material, can't in time discharge.

Summary of the invention

The utility model because there is big, the problem such as yield poorly of the extra power output of equipment in unreasonable structure, provides a kind of multichannel hammer mill in order to solve existing hammer mill.

The utility model is to adopt following technical scheme to realize: the multichannel hammer mill, comprise upper shell, lower house, the upper shell top is provided with charging aperture, the lower house below is provided with discharging opening, some following grate bars that circular arc is arranged that are also are housed in the lower house, also comprise the revolution impact assembly that is driven and had some tups by drive unit, innovative point of the present utility model is to be positioned at the upper shell of charging aperture below and descends the arrangement mode of grate bar to be provided with the grate bar along lower house.Described revolution is impacted assembly and is comprised belt pulley, rotating shaft and the parts such as rotating disk that are placed in rotating shaft, is existing known configurations.The utility model in upper shell, also set up some on the grate bar, when particle diameter less than the fine particle stage material of adjacent grate interspace in material inlet falls to upper shell the time, can directly drop down onto the discharging opening place through last grate bar adjacent segment, strike, impact, shearing, the abrasive action of the hammer of high-speed motion have been avoided being subjected to together along with the coarse fraction material, not only reduced the power output of equipment, reduce the wearing and tearing of equipment, and improved production efficiency greatly.

In order further to optimize the structure of this disintegrating machine, improve its function, the utility model has also carried out following structural design, the left and right sides of described upper shell one sidewall and be positioned at grate bar termination and have closeable through hole, and the forward and backward side of upper shell is respectively equipped with dodge gate.The size of described through hole is as the criterion to expose at least one grate bar.When equipment is in normal operating condition following time, through hole must be airtight, to prevent the positioning when the vibrations of grate bar, when pulverizing thin material, can play dustproof effect simultaneously; When needs changed the grate bar, dodge gate and two side through hole before and after opening, staff stretched into dodge gate and earlier a grate bar are sent by through hole, alternately remaining grate bar were pulled down one by one then and via through holes is sent, and new grate bar is installed equally according to the method described above.Adopt structural design of the present utility model, need not to dismantle under the situation of upper and lower casing, just can go up replacing, the maintenance of grate bar, simple in structure, time saving and energy saving, improved production efficiency greatly.

Described through hole is provided with the cover plate that flexibly connects with upper shell.Cover plate is as the containment member of through hole, simple in structure, convenient disassembly, the movable connection structure of cover plate and upper shell can adopt various ways, and for example cover plate is fixed by bolt and upper shell, also can be in through hole both sides fixed slot, the cover plate outside is provided with the pressing plate that is erected in the slot and cover plate is compressed.

The structure of described dodge gate can adopt multiple mechanical structure form to realize that the utility model only provides following structural design, and dodge gate and upper shell shell wall are hinged by contiguous block, bearing pin; Outside, dodge gate two ends is provided with the dodge gate latch that flexibly connects with the upper shell shell wall, is fixed with handle on the dodge gate.

Described two of being positioned at the upper shell the top go up the grate bar and all stretch out the upper shell sidewall.The effect of these two grate bars is to compress grate bar on all the other, grate bar positioning when preventing the equipment operation, even dish out, when changing,, also more convenient simultaneously because housing is stretched out at its two ends.

Compare with existing hammer mill, grate bar on the utility model is set up in upper shell, the fine grained stage material is drained into discharging opening at first, reduced the power output of equipment, the wearing and tearing of equipment have been reduced, and improved production efficiency greatly, parts such as through hole, dodge gate are set at upper shell simultaneously, can effectively stop up the cleaning of material and the replacing of grate bar, time saving and energy saving, improved operating efficiency greatly, simple in structure, reasonable in design, and improvement cost is lower, can be widely used in the fragmentation of materials such as building stones, sandstone, gangue.
