Abstract

The invention discloses a roll crusher. The roll crusher comprises a box. Two roll bodies which rotate oppositely are arranged in the box. Each roll body comprises a roll shaft, a roll main body and a lining board, wherein the roll shaft and the roll main body are fixed into a whole, the lining board is fixed to the roll main body, and the roll shaft is driven by a motor through a belt via a transmission wheel outside the box. Through holes are formed in the end faces of the roll shafts, and the middle portions of the roll shafts are hollow. Each lining board is of a combined type and is fixed to the exterior of the corresponding roll main body from the interior of the corresponding roll shaft through a fixing device. The through holes are connected with hot air pipelines. The roll crusher has the advantages that because the lining boards are manufactured in a segmented mode and then bolted or riveted, wearing parts can be conveniently replaced, lining boards of different materials, different sizes and different shapes can be replaced at any time according to different materials to be crushed, the lining boards are more durable, and the crushing cost is lowered. Through maintenance holes of the roll shafts, protection boards can be installed and maintained more conveniently and more rapidly, and time and labor can be saved. Through the hot air pipelines, wet materials can be dried.

Description

A kind of kibbler roll

Technical field

The present invention relates to mechanical field, is a kind of mining machinery specifically, is more specifically a kind of disintegrating machine.

Background technology

Kibbler roll utilizes two the running roller bodies rotated at a high speed relatively, extrudes and broken to the material entered, the operation principle of Here it is kibbler roll.

There is following point in kibbler roll in the market, be on the one hand its structure by rolling skin, roller, axle three part form, rolling skin interference fit is arranged on roller, once wearing and tearing are changed install inconvenience, working site cannot be installed at all, be its roller backplate and processing of roller complex process on the other hand, concentricity has error relatively.

Summary of the invention

For solving the problems of the technologies described above, the object of this invention is to provide a kind of new-type kibbler roll, its running roller and roll shaft are one or split manufacture, liner plate be segmentation with bolt conjunction or riveted on running roller, and maintenance installing hole is set, installation and repairing is more convenient, and add manhole and connect hot blast to the function of drying compared with wet stock, concrete scheme is as follows:

A kind of kibbler roll, comprises casing, arranges two running roller bodies relatively rotated in described casing; Described running roller body comprises roll shaft, running roller, liner plate, and described roll shaft and running roller are integrally fixed; Described liner plate is fixed on roller; Described roll shaft is driven by motor by belt by the drive outside casing; The end face of described roll shaft arranges through hole, and the mid portion of described roll shaft is hollow; Described liner plate is combined type, is fixed on the outside of running roller by fixture from roll shaft inside; Described through hole is connected with hot air duct.

For improving crushing efficiency, the radial dimension of described liner plate is different, the liner plate radial dimension being such as arranged on running roller body centre position is large a little, such one side can ensure that the material of this position is subject to larger pressure, the material in centre position can be squeezed to both sides on the other hand, thus ensure the surface uniform pressurized of material at whole running roller body.

Described fixture is that bolt is fixed, and namely bolt coordinates with the screwed hole be arranged on inside liner plate through running roller inside roll shaft, liner plate is fixed on the outside of running roller.

Described fixture is that riveted is fixed, namely rivet coordinates with the rivet hole be arranged on inside liner plate through running roller inside roll shaft, the opening of described rivet hole is slightly large compared with the external diameter of rivet, and the internal diameter of rivet hole is greater than the diameter of opening part, like this, when operating, from roll shaft inside impact rivet, rivet is owing to being subject to the stop of liner plate, and the rivet entering rivet hole can produce pier slightly, and then liner plate is fixed on the outside of running roller.

In addition, can be different according to material, the size dimension of adjustment liner plate and shape, to reach best crushing effect; Running roller and the processing of roll shaft one are to ensure concentricity.

Advantage of the present invention is:

By running roller and the processing of roll shaft one be ensure that concentricity, running roller running body is got up more steady.By liner plate sectional making, bolt is closing or riveted, thus it is convenient to change consumable accessory, also can change the liner plate of unlike material, different size and shape at any time by the material different according to fragmentation, make liner plate more durable, and greatly reduce broken cost.Installed and maintenance backplate by the manhole of roll shaft, make installation and maintenance more convenient and quicker, time saving and energy saving; Can be dried comparatively wet stock by the setting of hot air duct.

Fig. 1 is structural representation of the present invention;

Fig. 2 is roller body structural representation;

Fig. 3 is the scheme of installation of liner plate riveted;

Fig. 4 is another riveted construction schematic diagram.

Detailed description of the invention

Illustrate the present invention below in conjunction with accompanying drawing, as shown in Figure 1-Figure 3, the present invention includes and comprise casing 4, two running roller bodies 5 relatively rotated are set in described casing 4; Described running roller body 5 comprises roll shaft 6, running roller 8, liner plate 9, and described roll shaft 6 is integrally fixed with running roller 8; Described liner plate 9 is fixed on roller 8; Described roll shaft 6 is driven by motor 1 by belt 11 by the drive 3 outside casing 4; The end face of described roll shaft 6 arranges through hole 10, and the mid portion 7 of described roll shaft 6 is hollow; Described liner plate 9 is combined type, is fixed on the outside of running roller 8 by fixture from roll shaft 6 inside; Described through hole 10 is connected with hot air duct 12.

For improving crushing efficiency, the radial dimension of described liner plate 9 is different, liner plate 9 radial dimension being such as arranged on running roller body centre position is large a little, such one side can ensure that the material of this position is subject to larger pressure, the material in centre position can be squeezed to both sides on the other hand, thus ensure the surface uniform pressurized of material at whole running roller body.

For ensureing that installation and the maintenance of liner plate are carried out in inside that operator can enter roll shaft, the diameter of described through hole 10 is greater than 600mm.

Described fixture can also be fixed for riveted, as shown in Figure 3, rivet 13 coordinates with the rivet hole 14 be arranged on inside liner plate 9 through running roller 8 inside roll shaft, the diameter of the opening part of described rivet hole 14 is slightly large compared with the external diameter of rivet 13, and the internal diameter of rivet hole 14 is greater than the diameter of opening part, the bottom of rivet hole 14 arranges lug boss 15, like this, when operating, from roll shaft inside impact rivet 13, rivet is owing to being subject to the stop of the lug boss 15 that liner plate is arranged, it is thick that the rivet 13 entering rivet hole 14 can produce pier, and then liner plate 9 is fixed on the outside of running roller 8.

Riveted is fixed and can also be adopted the device shown in Fig. 4, and liner plate 9 is provided with the through hole of boss, and rivet 13 passes roll shaft 8 and roller, by liner plate 9 riveted on running roller 8.The shortcoming of this structure is porose on liner plate, easily produces solid accumulation; And the riveted construction shown in Fig. 3 can overcome this defect.

In addition, can be different according to material, the size dimension of adjustment liner plate and shape, to reach best crushing effect.

Running roller and the processing of roll shaft one; Concentricity can be ensured.
