Description
Technical field
The utility model relates to a kind of instrument, is specifically related to a kind of instrument for dismounting bearing, shaft seal.
Background technology
Method for floating is widely used in medicine and metallurgy industry, and the most general at metallurgy industry, the mineral being suitable for processing have copper, lead, zinc, tungsten, tin, platinum, nickel, antimony, mercury, sulphur, iron, gold, silver, lithium, beryllium, Rare Earth Mine and nonmetallic ore etc.Flotation device is the special equipment of Mineral Processing Industry, and wherein KYF type flotation machine is current most widely used inflating mechanical agitation type flotation machine, forms primarily of impeller, stator, hollow spindle, bearing body, air control valve and cell body.Wherein bearing body is the important component part of flotation device, and its Main Function supports the hollow spindle rotated, and connects impeller and rotates, thus the mixing of guarantee flotation, stirring and foaming effect.
In recent years, along with equipment enlarging development, Mineral Processing Industry selects 150 m gradually
3, 100 m
3, 50 m
3deng large flotation machines.Because flotation device volume and weight is very large, the front and back bearings of bearing body, shaft seal, all at about 15-30Kg, are fitted closely with bearing body.Therefore in the maintenance flotation device course of work in the past, particularly when dismounting bearing shaft seal, generally must be taken turns to knock bearing and shaft seal with rod iron sledgehammer by 2-3 good maintenance mans of fitness, labour intensity is very large, and easily damages bearing or shaft seal.Concrete grammar is: maintenance personal is withstood the edge of bearing and shaft seal by a personal thicker iron rod when dismantling bearing, shaft seal, another one people firmly beats iron rod with beating greatly, bearing and shaft seal is released from bearing body successively; Use the same method when the bearing that installation and maintenance are good and shaft seal and push in again.Although such method is easy, there is a lot of problem.On the one hand: disassembly and assembly time is long, the labour intensity of worker is larger.Compare fragmentation and grinding attachment, flotation device quantity is more, processes the ore dressing plant of 6000 tons a day, configure 55-60 platform 50m
3and 16m
3kYF flotation device, for a mammoth mill, the configuration quantity of each large flotation machines even reaches 200-300 platform.Maintenance personal will overhaul 5-10 platform flotation device every month, if dismounting, maintenance and installation one table flotation select the time of machine bearing body to be 10 man-hours (two people), work total amount is just very large, shortens the production time, reduces production efficiency; On the other hand, waste time and energy, accidentally also can damage bearing and shaft seal when knocking, affecting repair quality and inspection speed, sometimes also making part rejection, increase spare part expense.Bearing and shaft seal can cause part edge to knock damage because uneven gravity knocks in dismounting and installation process, because flotation device mainly realizes the mix and blend of ore pulp by means of the impeller of flotation cell bottom or the High Rotation Speed of revolution and is filled with air.Gas feeds central shaft by External Force Acting, and impeller plays main stirring, immixture.The breakage of bearing and shaft seal can make ore pulp flow into bearing body from breakage, causes bearing damage, reduces the velocity of rotation of flotation device central shaft and impeller, reduces the blowing pressure simultaneously, have a strong impact on the foaming effect of flotation device and completing of the key technical indexes.

Detailed description of the invention
As shown in figs 1 to 6, a kind of tool construction for dismounting bearing 1, shaft seal 2 of the present utility model comprises: fixed head 3, preferably, fixed head is leg-of-mutton steel plate, the mid portion of steel plate face is provided with three reinforcements 15, fixed head has a centre bore 4, around centre bore, has three fixing holes 5 equably; Thrust frame 6, thrust frame structure comprises between two distance rods, 7, two distance rods of being oppositely arranged with fixed head and is provided with a connecting rod 8 and a bracing piece 14, and connecting rod is provided with the bolt hole 9 relative with fixed head central hole location; Rotary screw 10, rotary screw is the screw rod that one end passes in fixed head centre bore, precession connecting rod upper bolt hole, and the other end of rotary screw is provided with the nut 11 matched; One end of fixing screw mandrel 12, three fixing screw mandrels is passed in the fixing hole on fixed head, the screw on precession bearing, and the other end is screwed by three nuts 13 matched.
During use, rotary screw selects the screw rod of a M22 material 500mm, and fixing iron plate body is the subtriangular steel plate of M25, and the three 15*20mm reinforcements in center are reinforced, and increases the strength and stability of fixing iron plate body.Being designed to leg-of-mutton object is the principle the strongest according to stable triangular, and three fixing elongated holes on fixing iron plate body are designed to 130mm, can meet 8 m so simultaneously
3, 16 m
3, 50 m
3, 100 m
3with 150 m
3the maintenance of flotation device bearing body and dismounting, installation.In order to attractive in appearance and safety, fixing iron plate body edge designs has become circular arc, does not have other using function.
Dismounting bearing, shaft seal implementation process: during flotation device Disintegration overhaul, first its bearing body is laterally placed on the ground, be fixed on the screw on flotation device bearing body by the stud of three fixing screw mandrels and M20 one of bearing body front port, then the other end of fixing iron plate body nut and three studs is fixed.After these two parts are fixing, the bearing of its axis and flotation device bearing body in the same way and overlap, such active force just can with the bearing dismantled and shaft seal at grade, ensure that the uniform force of bearing, shaft seal.Rotary screw is passed fixing iron plate body centre bore from outside, makes rotary screw one end nut and fixing iron plate body reach the degree fitted tightly, the other end uses rotary nut be connected with thrust frame and fix.So just thrust frame is fixed on the outside of bearing, shaft seal.Then or pneumatic impact spanner pneumatic by rotates clockwise rotary screw by sleeve, then drives thrust frame by rotary screw, and the bearing or shaft seal that are placed into bearing body port at the uniform velocity, are stably balanced pull-out from bearing body.
Bearing, shaft seal implementation process are installed: when the new shaft seal of having overhauled and bearing being pushed, the same with said process, at the front port place of flotation device bearing body.First one of the stud of three fixing screw mandrels and M20 is fixed on flotation device bearing body, then the other end of fixing iron plate body nut and three studs is fixed.After these two parts are fixing, the bearing of its axis and flotation device bearing body in the same way and overlap, such active force just can with the bearing dismantled and shaft seal at grade, ensure that the uniform force of bearing, shaft seal.Then by rotary screw from the centre bore of inner side through fixing iron plate body, to be equally also connected with thrust frame by rotary nut and to fix.But with unloading process by contrast, thrust frame to be put into the inner side of bearing or shaft seal, finally coordinated by sleeve by means of pneumatic or pneumatic impact spanner, rotate counterclockwise rotary screw, drive thrust frame shaft seal, bearing can be advanced in bearing body respectively by screw mandrel, and can ensure at the uniform velocity with the balance of turnover, any damage is not caused to bearing body and bearing, shaft seal.
Tool making of the present utility model is reasonable, quick and easy laborsaving, can according to regulating the length of fixing iron plate elongated hole and the dismounting of bolt fixed position and installing various large and medium-sized flotation device and other equipment bearings, shaft seal.Can a tool multiplex, save spare part expense, greatly shorten repair time and labour intensity.In addition, can repair quality be ensured, reduce floatation equipment fault time, improve flotation operation efficiency, for the stable of beneficiating technology index with optimize lifting and provide safeguard.
