Abstract
The utility model discloses an anti-blocking ring hammer crusher comprising a bottom plate, wherein the bottom plate is provided with a base and a shell; the side wall inside the shell is provided with a lining plate; the shell is internally provided with a main ring hammer body on which ribs are distributed; a main shaft is arranged at the center of the main ring hammer body; two ends of the main shaft are provided with dustproof sealing devices; the top end of the main shaft is connected with a motor through a shaft coupling after passing through the shell; the outer wall of the shell is provided with an access door; and a feeding hole is formed above the shell. The particle size can meet the requirement after particles are crushed, and no blocking phenomenon is caused. The anti-blocking ring hammer crusher has the advantages of simple structure, excellent performance, small fault rate, small maintenance quantity and the like.
Description
Technical field
The utility model belongs to the technical field of material crushing, relates to a kind of equipment of material crushing sampling.A kind of anti-blocking ring hammer crusher that is adapted to power plant soot sampling particularly.
Background technology
Entering the stove coal sample is the sample segment that represents to a certain extent into stove coal average quality.The analytical test result that enters the stove coal sample can be used as the foundation of estimating stove ature of coal amount.The calorific value that enters the stove coal sample has very large impact to the thermal efficiency of determining boiler of power plant.Enter on the belt of the former coal sample of stove in induction system or the coal breakage place takes.For any part that guarantees raw coal has identical chance to be taked, reach sampling precision, enter the former coal sample of stove coal take should use the mechanical sampling device.
Use the mechanical sampling device to adopt to such an extent that should make immediately the total moisture sample after former coal sample, and carry out the total moisture check.Therefore, the fragmentation and the sample division mechanism that have usually comprised preliminary preparation total moisture sample in entering stove coal Sampling Machine.In the preparation method of national standard coal sample (GB474-2008), the granularity of regulation total moisture sample is less than 6mm.Here it is enters the fineness requirement of stove coal Sampling Machine crushing mechanism.
Present common vertical ring hammer disintegrating machine is to make the granularity of coal sample reach requirement by the aperture of determining sieve plate.Feasible on this theoretical method.But in the process of actual motion, being subjected to the variation of raw coal water content and entering the sampling of stove coal is the impact of intermittent sampling, and sieve plate often stops up, and raw coal easily lumps in disintegrating machine, overcurrent, even motor damage when causing disintegrating machine to start.
Summary of the invention
For the problem that common vertical ring hammer disintegrating machine exists in entering the sampling of stove coal, the purpose of this utility model is, a kind of Novel anti-blockage ring hammer crusher that is applied to the material sampling prototype is provided.
In order to realize above-mentioned task, the utility model adopts following technical solution:
A kind of anti-blocking ring hammer crusher, comprise base plate, base and housing are arranged on base plate, it is characterized in that, on sidewall in housing, liner plate is arranged, ring hammer main body is arranged in housing, be distributed with rib on ring hammer main body, there is main shaft in ring hammer main body central authorities, there is dust-proof sealing device at the main shaft two ends, the main shaft top is passed housing and is connected motor by shaft coupling, on the housing outer wall, access door is arranged, and is provided with charging aperture above housing.
Other characteristics of the present utility model are:
Described ring hammer main body is with multilayer ring hammer and ring hammer connecting plate, and is penetrating between every layer of ring hammer, without middle baffle plate.
The inwall of described liner plate is the light face, only by rib controlled fragmentation effect.
Anti-blocking ring hammer crusher of the present utility model, can realize broken after particle diameter reach requirement, and the phenomenon stopped up does not appear.Have simple in structure, function admirable, the advantage such as fault rate is little, and maintenance is few.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Mark in figure represents respectively: 1, base plate, 2, base, 3, dust-proof sealing device, 4, main shaft, 5, ring hammer main body, 6, liner plate, 7, housing, 8, access door, 9, shaft coupling, 10, charging aperture, 11, motor, 12, rib.
The utility model is described in further detail below in conjunction with drawings and Examples.
The specific embodiment
Technical thought of the present utility model is to cancel the known intersubjective baffle plate of ring hammer of ring-hammer type crusher, elimination is accumulated material between baffle plate and ring hammer connecting plate hidden danger; The structure of liner plate is smooth cylinder, by position and the size of the material particles after the appearance and size controlled fragmentation of the rib that welds on liner plate, has simplified the structure of liner plate, has reduced the wearing and tearing of liner plate.
Referring to Fig. 1, the present embodiment provides a kind of Novel anti-blockage ring hammer crusher, comprises base plate 1, and base 2 and housing 7 are arranged on base plate 1, liner plate 6 is arranged on the sidewall in housing 7, ring hammer main body 5 is arranged in housing 7, be distributed with rib 12 on ring hammer main body 5, there is main shaft 4 in ring hammer main body 5 central authorities, there is dust-proof sealing device 3 at main shaft 4 two ends, main shaft 4 tops are passed housing 7 and are connected motors 11 by shaft coupling 9, on housing 7 outer walls, access door 8 are arranged, and housing 7 tops are provided with charging aperture 10.
In the present embodiment, ring hammer main body 5 is with multilayer ring hammer and ring hammer connecting plate, and is penetrating between every layer of ring hammer, without middle baffle plate.The inwall of liner plate 6 is the light face, only by rib 12 controlled fragmentation effects.
Adopt anti-blocking ring hammer crusher of the present utility model, after start, motor 11 is by shaft coupling 9 band main shafts 4 and 5 rotations of ring hammer main body, the animal material enters in housing 7 from charging aperture 10, after material particles is hammered the upper strata ring hammer and upper strata ring hammer connecting plate shock of main body 5 into shape with ring, got rid of to surrounding by centrifugal action, along liner plate 6 inwall tenesmus.When material particles arrives rib 12 position on top, from the gap tenesmus of rib 12 and ring hammer connecting plate to middle level ring hammer, larger particles will repeatedly be impacted, roll, be crushed to particle diameter by middle level ring hammer and hammer the gap of connecting plate less than upper strata rib and upper strata ring into shape than granule.
When material particles arrives rib 12 position at middle part, drop to lower floor's ring hammer from the rib 12 at middle part and the gap of middle level ring hammer connecting plate than granule, larger particles will be encircled hammer by lower floor impact, roll, be crushed to particle diameter repeatedly less than the gap of middle level rib 12 with middle level ring hammer connecting plate.
When material particles arrives rib 12 position of lower floor, drop to discharging opening with the gap that lower floor encircles the hammer connecting plate than the rib 12 of granule from lower floor, larger particles will repeatedly be impacted, roll, be crushed to particle diameter by lower floor's ring hammer and hammer the gap of connecting plate less than lower floor's rib and lower floor's ring into shape.
