Abstract

The utility model relates to a blocking-free reversible crusher, which relates to the field of crushing in a work part. The utility model is mainly used for coal, ores, coke, etc., and is especially suitable for a sample preparing system of the coal. The utility model is characterized in that toothed plates 7 are arranged symmetrically to both sides of a rotor 1; the toothed plates 7 are arranged on a supporting plate; a hammer head 5 is hung on a hammer pin 4. The utility model has the advantages of uniform discharge granularity, little over crushing, large yield, low energy consumption, reversibility, convenient maintenance, long service life but no sieve plates or block, and the utility model has no especial requirements to the water content of material.

Description

There is not the reversible of obstruction disintegrating machine

The utility model relates to the broken field of homework department, is that a kind of nothing is stopped up the reversible disintegrating machine.Be mainly used in coal, gangue, compression strength such as slag, shale, coke, galena, siderite, loose lime stone, zincblende, limonite are no more than the material fragmentation of 150MPa, particularly are fit to the coal sample-preparing system.

Having single rotor both at home and abroad now, arrange hammer mill more, is the unidirectional type disintegrating machine, mainly partly is made up of casing, rotor, grid section and beater plate etc.Circular-arc discharging grate is installed in the rotor below, hang with tup on the rotor, have pin-and-hole on the tup, be used for adjusting the gap between tup and the grate, when rotor high-speed rotates, tup under the effect of centrifugal intertia force, do radial to around scatter, enter that material in the machine is subjected to that tup hits and broken.Then, because material obtains kinetic energy, to impact or run foul of each other and broken to the beater plate that liner plate is housed at a high speed.The material that is broken draws off downwards less than the comb seam that passes through of grate seam, small part does not reach the material of requirement size and still stays on the compass screen surface, continue to be subjected to the impact and the mill stripping of tup, after reaching the requirement size, draw off from the seam of combing, owing to be provided with sieve, when material moisture is big slightly, material rests on and continues on the sieve plate to be impacted and grind when stripping, forms the cake piece easily and stops up the grid section seam, causes the disintegrating machine clogging.

The purpose of this utility model provides a kind ofly not to be had sieve plate but does not have the disintegrating machine that stops up and can reverse rotation.

The purpose of this utility model is achieved in that

The pure collision principle of main utilization is carried out fragmentation to material.Structurally in this machine central authorities rotor is set, is symmetrical in the rotor both sides and is provided with adjustable broken tooth plate, rotor can two-wayly rotate, and has formed invertibity; Broken tooth plate can be opened as opening with side door, because of need not sieve plate, stops up thereby realize not having.Its detailed process that realizes operation principle is such: the tup that the material that falls from charging aperture is at first rotated at a high speed hits and broken, then because material obtains kinetic energy with at a high speed to broken tooth plate or percussion and fragmentation mutually.Immediately with the tooth plate bounce-back of being broken to tup or other tooth plate of rotation at a high speed or run foul of each other and broken.Material is in the crusher chamber of broken tooth plate and tup track formation.Impact back and forth so repeatedly.Be crushed to step by step and met the requirements of size, drawn off from the discharging opening of disintegrating machine bottom.Its discharging-material size can arbitrarily be adjusted by broken tooth plate governor motion.Material mainly is hit in broken overall process, collides and fragmentation.

Concrete structure of the present utility model is provided by following examples and accompanying drawing:

Fig. 1 is the utility model structural representation

Now be described in detail in conjunction with the accompanying drawings:

As shown in Figure 1, the utility model comprises: 1. rotor, 2. main shaft, 3. dividing plate, 4. hammer pin, 5. tup, 6. frame, 7. tooth plate, 8. supporting plate, 9. side door, 10. governor motion.

It is characterized in that: the both sides that are symmetrical in rotor 1 are provided with tooth plate 7, and tooth plate 7 is installed on the supporting plate 8; Tup 5 is hung on hammer pin 4.

On the bearing of frame 6, the other end links to each other with governor motion 10 with axis suspension in the upper end of supporting plate 8, and hammer pin 4 is installed on the dividing plate 3, and dividing plate 3 is fixed on the main shaft 2.Tooth plate 7 constitutes crusher chamber (being used to regulate the gap of tooth plate and tup) with tup 5 movement locus.Tooth plate 7 and supporting plate 8 are fixed on the side door 9.

The body top is provided with charging aperture, and the bottom is provided with discharging opening.

The utility model has the advantage of: discharging-material size is even, crosses to pulverize and lacks, and output is big, energy consumption Low; Have invertibity, but the rotor Double-directional rotary makes and revolves hammer and broken tooth plate uniform wear, minimizing Shut down to change the frequency of consumable accessory; Its symmetric design makes the installation of motor not have a left side The branch on the right side has improved the free degree that equipment is installed greatly; The both sides side door of disintegrating machine can be opened Open to putting property, make the replacing of consumable accessory convenient, shortened downtime. Repair and maintenance Convenient. No sieve plate does not stop up. Need not worry the obstruction of material in crusher chamber, and to material Surface moisture do not have specific (special) requirements yet. So be specially adapted to the in small, broken bits of material. This advantage is kept away Exempted from general disintegrating machine and made the consumable accessory unstable wear because of the delay of material in crusher chamber, namely Prolonged the service life of disintegrating machine consumable accessory.
