Description

A kind of heavy hammer mill

Technical field

This utility model relates to disintegrating machine technical field, particularly to a kind of heavy hammer mill.

Background technology

Disintegrating machine refers to that in discharge, the granularity content more than three millimeters accounts for the size reduction machinery of total withdrawal rate more than 50%. Crushing operation often by the size of feed and marker size be divided into coarse crushing, in broken and in small, broken bits. Conventional sandstone equipment has jaw crusher, impact breaker, hammer mill, kibbler roll etc. Hammer mill is the direct broken disintegrating machine that the material that maximum particle size is 600-1800 millimeter is crushed to less than 25 or 25 millimeters, hammer mill is applicable at cement, chemical industry, electric power, the industrial departments such as metallurgy crush medium-hard material, such as limestone, slag, coke, operation broken, in small, broken bits in the material such as coal.

Existing hammer mill, the bearing of its rotor mechanism adopts grease lubrication, and bearing box is poorly sealed, and dust enters and causes Bearing Temperature, serious wear, affects the service life of bearing; It addition, the liner plate on existing disintegrating machine counterattack wall is waveform liner plate, cycle is few, and lamellar and needle-like material easily occurs in building stones grain type.

Utility model content

This utility model provides a kind of heavy hammer mill, solves the problem that existing hammer mill bearing wear is serious and then affects bearing service life.

For solving above-mentioned technical problem, the technical solution adopted in the utility model is:

A kind of heavy hammer mill, including body, described body upper end is provided with charging aperture, described body inwall is downwardly extending the counterattack wall of arc along described charging aperture, it is provided with rotor mechanism in described body, described rotor mechanism includes rotating shaft, bearing and bearing block, described bearing is arranged on the two ends place of described rotating shaft, bearing sleeve is located at the outside of bearing, described bearing block is outside equipped with bearing cap, it is provided with sealing member in the endoporus of described bearing cap, it is arranged with oil baffle disc between described sealing member and described bearing, annular gap is formed between described oil baffle disc and described bearing.

Wherein it is preferred to, described sealing member is outside framework oil seal, described outside framework oil seal at least two, is arranged in side by side in the endoporus being placed in described bearing cap on described rotating shaft.

Wherein it is preferred to, described bearing block is provided with tank filler sleeve.

Wherein it is preferred to, described rotating shaft is also arranged with labyrinth bush, the outer wall circumference of described labyrinth bush is provided with at least two annular groove, and the inner peripheral surface of described bearing block is provided with the boss matched with described annular groove.

Wherein it is preferred to, described counterattack wall is provided with sharp-tooth shaped liner plate.

The beneficial effects of the utility model:

1. this utility model changes the lubrication portion of rotor mechanism into thin oil lubricant, and bearing box seals more tight, and dust does not enter back into bearing, reduce the abrasion of bearing so that bearing is under heavy load working order, and temperature rise is less than 30 DEG C, improve the service life of bearing, reduce maintenance cost.

2. this utility model changes rear lining plate as counterattack type liner plate into, increases cycle, and liner plate changes into sharp-tooth shaped liner plate, reduce lamellar and the output capacity of needle-like material.

Accompanying drawing explanation

In order to be illustrated more clearly that this utility model embodiment or technical scheme of the prior art, the accompanying drawing used required in embodiment or description of the prior art will be briefly described below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the premise not paying creative work, it is also possible to obtain other accompanying drawing according to these accompanying drawings.

Fig. 1 is the structural representation of this utility model embodiment;

Fig. 2 is the structural representation of this utility model embodiment rotor mechanism.

In figure, 1. body, 2. charging aperture, 3. counterattack wall, 4. rotor mechanism, 4-1. rotating shaft, 4-2. bearing, 4-3. bearing block, 4-4. bearing cap, 4-5. oil baffle disc, 4-6. outside framework oil seal, 4-7. tank filler sleeve, 4-8. labyrinth bush, 5. sharp-tooth shaped liner plate.

Detailed description of the invention

Below in conjunction with the accompanying drawing in this utility model embodiment, the technical scheme in this utility model embodiment is clearly and completely described, it is clear that described embodiment is only a part of embodiment of this utility model, rather than whole embodiments. Based on the embodiment in this utility model, the every other embodiment that those of ordinary skill in the art obtain under not making creative work premise, broadly fall into the scope of this utility model protection.

As depicted in figs. 1 and 2, the present embodiment provides a kind of heavy hammer mill, including body 1, body 1 upper end is provided with charging aperture 2, body 1 inwall is downwardly extending the counterattack wall 3 of arc along charging aperture 2, rotor mechanism 4 it is provided with in body 1, rotor mechanism 4 includes rotating shaft 4-1, bearing 4-2 and bearing block 4-3, bearing 4-2 is arranged on the two ends place of rotating shaft 4-1, bearing block 4-3 is set in the outside of bearing 4-2, bearing block 4-3 is outside equipped with bearing cap 4-4, it is provided with sealing member in the endoporus of bearing cap 4-4, oil baffle disc 4-5 it is arranged with between sealing member and bearing 4-2, annular gap is formed between oil baffle disc 4-5 and bearing 4-2. at sealing member for being provided with oil baffle disc 4-5, it is possible to further prevent lubricant grease from having seepage. this structure adopts thin oil lubricant, and bearing box seals more tight, and dust does not enter back into bearing 4-2, reduce the abrasion of bearing 4-2 so that bearing 4-2 is under heavy load working order, and temperature rise is less than 30 DEG C, improve the service life of bearing 4-2, reduce maintenance cost.

Wherein, sealing member is outside framework oil seal 4-6, and outside framework oil seal 4-6 is two, is arranged in side by side in the endoporus being placed in bearing cap 4-4 on eccentric shaft. In this utility model, it is possible to be set up in parallel multiple outside framework oil seal 4-6, skeleton oil 6, just as the reinforcing bar inside concrete component, plays the effect of reinforcement, and makes oil sealing can keep shape and tension force.

Wherein, bearing block 4-3 is provided with tank filler sleeve 4-7, it is simple to refuel timely.

Wherein, rotating shaft 4-1 is also arranged with labyrinth bush 4-8, the outer wall circumference of labyrinth bush 4-8 is provided with at least two annular groove, the inner peripheral surface of bearing block 4-3 is provided with the boss matched with annular groove, the relative operating between labyrinth bush 4-8 with bearing block 4-3 is made not produce friction, in relative operation process, form air wall, effectively stop oil leak.

Wherein, counterattack wall 3 is provided with sharp-tooth shaped liner plate 5. Mostly existing strike liner plate is waveform liner plate, and cycle is few, and lamellar and needle-like easily occurs in building stones grain type, by improving, rear lining plate is changed into the counterattack type liner plate of sharp-tooth shaped, increases cycle, reduces the output capacity of lamellar and needle-like material.

The foregoing is only preferred embodiment of the present utility model; not in order to limit this utility model; all within spirit of the present utility model and principle, any amendment of making, equivalent replacement, improvement etc., should be included within protection domain of the present utility model.
