Abstract

An annular reverse breaker relates to a novel break device for meeting the granularity demand of the boiler material of circulating vulcanizing bed. The utility model is based on the working theory of annular hammer breaker, wherein the break process comprises that using three sections to treat the material as first roughly breaking, middle breaking and finely breaking, to obtain needed granularity. The utility model is characterized in that a rotor element is mounted with a plate hammer engaged with an annular hammer, the body and a back cover element are respectively mounted with a rough break plate, an adjustable middle break plate, and a fine break plate, a front cover element is mounted with a dial element and a foreigner room. For meeting the break ratio between the middle break and fine break processes, and confirming the needed granularity, the utility model is mounted with two couples of screen plate adjusters. And since the plate hammer generates reactive force and cyclone force in high-speed rotation on the material, the material can be discharged quickly from the slim holes of the fine break plate, without block.

Yet for reaching the requirement of furnace size, adopting the disintegrating machine of general pattern to process also is the comparison difficulty.Because it is more assorted to advance the fuel band of power plant, the ratio of reduction is big again, and it is also many that it contains foreign material (as: wooden unit, stone, iron block and plastic products etc.), all is the unfavorable factor that influences the disintegrating machine discharging-material size.If the ratio of reduction surpasses more than 10, (material size/discharging-material size), not only crushing efficiency descends, but also energy consumption is increased, and is very uneconomical.

At above-mentioned situation, we now develop the trans disintegrating machine of ring of utility model particulate according to the development experience accumulation of being engaged in sieve, broken plant equipment for many years.

Summary of the invention.

The purpose of this utility model provides the trans disintegrating machine of a kind of ring, it adopts the rotor part that refills for bar in ring crusher, parts such as carse, medium and small slashings also are housed simultaneously combine, thereby satisfy the requirement of circulating fluidized bed boiler material size with it.

The purpose of this utility model is achieved in that it comprises breaker and crushing chamber, it is characterized in that being equipped with on the rotor part of breaker bar is complementary with the ring hammer, crushing chamber is formed arc anvil chamber by coarse crushing plate, middle slashings and three parts of plate in small, broken bits, the control assembly of the radial spacing of the inner surface of its arc screening plate and rotor ring hammer rotary work circle is equipped with the sieve plate adjuster.

The beneficial effects of the utility model are: because this machine is equipped with bar and the ring hammer is worked simultaneously, comprehensive crushing force increases, and borrows the rotation wind-force of its bar work, and broken thing is down then discharged rapidly, and non-blocking screen.

From Fig. 1 as seen: after material is gone into machine, the rotor that ring hammer, bar are housed that just is subjected to rotating at a high speed execute circumferentially, the effect of radial load, make it to arrange the material of coarse crushing lumpiness down, just can enter second section medium crushing from the radial spacing in first section coarse crushing plate and working rotor garden.In like manner change the 3rd section thin sieve plate that has bar shaped over to and finish fine crushing process.Promptly reach the thing of granularity requirements, just from the strip crevice hole of sieve plate, fall, thereby obtained the purpose of work in small, broken bits.

Description of drawings:

Fig. 1 is the trans disintegrating machine operation principle schematic diagram of ring.

Fig. 2 is the trans disintegrating machine mechanical construction drawing of ring, 2 (a), front view, 2 (b), cutaway view.

The specific embodiment:

Below in conjunction with embodiment and Fig. 2 mechanical realization of the present utility model being done one specifies.

From Fig. 2 as seen, the trans disintegrating machine of ring of the present utility model, it comprises that body 1, preceding cover 2, back cover 3, rotor 4, middle slashings 5, plate in small, broken bits 6, sieve plate adjuster 7 and motor etc. partly constitute.

1, airframe components: it has feeding mouth in body upper, and the both sides, middle part have the rotor bearing seat board, and adjustable setting gauge down is equipped with in the place ahead in body, and its axial cambered surface is made the rectangle slotted hole, so that get rid of broken thing down.It is by two groups of pipe supports and leading screw, and the nut bearing drags, and can reach fine setting.The thing that can not be broken can be dialled after the last material toggling in preceding cover by it, it is thrown in the broom closet.

Body is to be made by plate welding structure spare, and all and contacted inner surface of material all is equipped with abrasion-proof backing block in it.It is convertible with hinging pin shaft and forward and backward cover and is assembled together., be fixed after the triplicity plate tightening sealing with fastenings.

2, preceding cover parts: this machine is provided with broom closet (thing that can not be broken is as wooden unit, iron block etc.) and goes up setting gauge for inherently safe protection and impurities removal thing in it, and foreign material can be mad inright in damaging parts like this.For ease of foreign material in current check and the removing broom closet, a fan cleaning door is equipped with at its back side.

Cover is made with the plate weldment, and inner surface also is equipped with the protection liner plate.

3, back cover parts: it be coarse crushing, in pith in the broken formation shattering process, the higher coarse crushing plate of fixed wearability is housed in it, outstanding the holding of middle slashings hangs on the axle bed, is particle degree requirement in guaranteeing, two groups of screw rods, nut type adjusters are contained in it behind on the middle slashings.So that ordinary maintenance, its back side also have a cleaning door.

4, rotor part: it is the core of disintegrating machine, mainly by main shaft, two disks, several hammer dishes.Parts such as ring hammer, bar, hammer axle and bearing, bearing block, shaft coupling are formed.General and asynchronous machine is complementary, and does directed rotary work.The ring hammer, bar is a strength member in the rotor part, it selects for use shock-resistant wear-resisting again smart cast steel to make.It is distributed on the garden dish respectively, hammer coils all hole sites, wears spacing by the hammer axle and locatees work again.And in the ring hammer work by its centrifugal action, and presenting peripheral force, its rotation is revolved round the sun again, move as planet.And bar maintains static by hammer axle, and it only applies hitting power to material in the work, thereby produces the counterattack effect, make material coarse crushing and in during broken process, hammering can obtain broken purpose more fully repeatedly.Simultaneously, also borrow the whirlwind power that it produced and act on particle in small, broken bits and can promptly from the hole, slit of thin sieve plate, blow off away.
