Description

There is not the hammer disintegrating machine

The utility model relates to a kind of material crushing device, and is especially a kind of not with the disintegrating machine of tup.

China Patent No. 2L93225886.7 discloses a kind of disintegrating machine, comprise charge door, vertical axis, bearing block, horizontal rotor, crushing chamber, base, belt pulley and discharging opening, an end that it is characterized in that the horizontal rotor circumference place, blade and blade position of horizontal rotor is provided with the delay piece, the other end of blade is provided with the windrow piece, and bearing block is provided with cooling jacket.It can play cushioning effect to temporary impact load, avoid vibration, material being passed to the heat energy of machine takes out of outside the machine, guarantee the normal condition of work of bearing, its weak point is to adopt circulating oil lubrication, and water jacket cool cycles oil will be joined a table oil pump like this, the lubricating oil price is higher, and the compact inadequately problem of complete machine structure.

The purpose of this utility model just provides a kind of employing grease lubrication bearing, strengthens cooling bearing seat with the open type cooling water, makes the operating temperature nothing hammer disintegrating machine in shape all the time of bearing.

The utility model is made up of motor, main shaft, bearing block, feed box and fuselage etc., the main shaft lower end is a belt pulley, the upper end is the bearing material rotating disk, in the bearing material rotating disk discharging opening is arranged, discharging opening becomes volute shape, on the same horizontal level of bearing material rotating disk the crusher chamber that is contained on the fuselage is arranged, feed box is contained in the fuselage.The main shaft middle part has the bearing block of two-chamber, and there is lid at the bearing block two ends, between bearing block and the main shaft bearing are arranged, and water inlet pipe, outlet pipe and oil filling pipe are arranged on the bearing block.Crusher chamber and fuselage bevel, the crusher chamber inner surface is equipped with liner plate.

The utility model adopts lubricating grease (calcium-sodium soap grease) lubricating bearings, strengthens cooling bearing seat with the open type cooling water, solves its heat radiation, makes the operating temperature of bearing be in good state all the time, can prolong the service life of bearing; In the time will overhauling the replacing bearing, as long as untie the connecting bolt feeding cylinder of slinging, pull down the bearing material rotating disk, the crusher chamber of slinging again, take out two feed boxes, unclamp belt, untie the connecting bolt of bearing block and bearing bracket, just can overhaul main shaft outward with the bearing block machine that hangs out, has compact conformation, characteristics easy to maintenance, and because of there not being tup, so saved the trouble that needs often to change tup.In addition, during host work, cooled hot water is concentrated in the pond usefulness that can supply ablution, wash one's hands.

Below in conjunction with accompanying drawing, the utility model will be further described.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the cutaway view of A-A among Fig. 1.

Please read Fig. 1, motor 14 connects big belt pulley 13 and small belt pulley 11 by narrow V belt 12, main shaft 7 is fastened in the small belt pulley, the main shaft upper end is equipped with bearing material rotating disk 4, the discharging opening that three volute shapes are arranged in the bearing material rotating disk on the same horizontal level of bearing material rotating disk, on the fuselage is crusher chamber 2 by being bolted to, crusher chamber and fuselage 5 angles at 45, the crusher chamber inner surface is equipped with liner plate 3 by bolt.Feeding cylinder 1 is arranged directly over the bearing material rotating disk, and be connected with crusher chamber by bolt.The bearing block 8 that has two-chamber is enclosed within the middle part of main shaft, be welded with oil filling pipe 6 in the bearing block, water inlet pipe 9 is welded in the bottom of bearing block, outlet pipe 15 is welded in the top of bearing block, between bearing block and the main shaft bearing is housed, the bearing block upper and lower side has lid, and connects with bolt, and labyrinth sealing circle and oil seal washer are dustproof, the oil-sealing arrangements of lid.Support with bearing bracket 10 the bearing block lower end, and bearing bracket is fixed on the base plate of fuselage.Have two row's discharging openings on the fuselage base plate, feed box 16 make six split type, be enclosed within the fuselage both convenient mounting or dismounting, convenient again the making.

When the utility model breaks grog, connect advancing of bearing block earlier, outlet pipe, open switch then, when cooling water flow out of, outlet pipe can start running, when material in feeding cylinder introducing machine, drop on the bearing material rotating disk that high speed rotating, under gravity and action of centrifugal force, material penetrates from three tapping channels that volute shape is arranged with the speed of setting, beating is having on the crusher chamber that has liner plate of constant slope, material at first piles one deck stockpile very soon on the liner plate surface, and then the high energy material that penetrates is beaten on stockpile in the short time fiercely at the utmost point, thereby produces huge impact force, material in the crusher chamber is under the continuous bump of this impact force, be broken, grinding, the material after in small, broken bits outside feed box is discharged body, Here it is material and material oneself collide from impact principle.

During the broken raw material of the utility model, can not open cooling water switch, operation principle is identical during with process and broken grog.

The utility model is applicable to the two-stage crushing of the fragmentation, particularly clinker of industries such as mine, chemical industry, building materials, more shows its advantage.
