Description

A kind of Vertical Mill striker plate automatic regulating apparatus
Technical field
The utility model relates to a kind of Vertical Mill striker plate, especially a kind of Vertical Mill striker plate automatic regulating apparatus.
Background technology
Current, in the powder model system of cement plant, Vertical Mill, as a kind of main powder apparatus, is widely used the occasions such as powder raw material, cement, coal dust.Vertical Mill has stable mechanism performance, preferably abrasive efficiency and longer life-span.The important structure of Vertical Mill is exactly Burnisher apparatus and millstone device.In millstone device, striker plate is important building block.The height of striker plate determines the thickness of the mill bed of material, and can the whether suitable grinding machine that is directly connected to of thickness of feed layer stably run, and known by practical production experience, and when the bed of material is crossed thin, mill efficiency can reduce and grinding machine also may be out of service because there are vibrations; When the bed of material is too thick, mill efficiency can reduce and can produce " full mill " phenomenon.So solve the problem of striker plate, being also the most important thing, is improve production efficiency of equipment to reduce costs one of indispensable factor.
Chinese invention patent CN103084240A discloses a kind of Vertical Mill striker plate on-line tuning device, comprises striker plate, substrate, limited block, mill etc.Striker plate is on substrate, and by the connection of chute and substrate, along with mill rotates, striker plate outwards rotates along chute direction under the influence of centrifugal force, the striker plate height that different speed of grinding plate is corresponding different.Adjust engine speed by frequency converter, change speed of grinding plate, the centrifugal force that adjustment striker plate is subject to, thus achieve on-line tuning striker plate height.But the subject matter existed has: grinding machine is when operating, there is a large amount of dust, dust piles with chute, when speed of grinding plate reduces, can not ensure that striker plate can slide along chute normally, the proper height required for guarantee, same reason, in rotating speed raising situation, can not ensure that striker plate slides into suitable height.Chinese patent CN102974429A relates to a kind of collet device for roller type vertical mill mill, its main device is made up of fixed stop feed ring, adjustable collet, adjusting bolt and adjusting nut, its main feature is adjustable collet is be spliced by two hemizonids of symmetry division after whole circle processing, and described adjustable collet is along the circumferential direction divided into 12 pieces of combinations and installs.Its main method is placed in by adjustable collet by the fixing adjustable ring of guide ring, collet can be regulated to coordinate with fixed stop feed ring by adjustable ring, reach the height of needs.But there is subject matter to have: striker plate is the height being ensured striker plate by the thickness superposition of adjustable collet, can not ensure that the superposition of collet thickness just reaches required thickness, because adjustable collet is separately symmetrical, under the operating mode of grinding machine complexity, clamp nut is probably caused to unclamp, adjustable ring landing, seriously may cause the destruction of machine.
Summary of the invention
For the problems of the prior art, the utility model provides a kind of Vertical Mill striker plate automatic regulating apparatus, the Vertical Mill striker plate automatic regulating apparatus of adjustment striker plate height automatically under the state namely do not stopped production at Vertical Mill grinding machine.
Vertical Mill striker plate automatic regulating apparatus of the present utility model comprises striker plate 1, support I 3, inflator mechanism 10, support I 3 is fixed on the dish seat 5 of grinding roller, striker plate 1 is arranged on support I 3 by pin I 2, the dish seat 5 that inflator mechanism 10 is fixed on grinding roller is arranged on below striker plate 1, and inflator mechanism 10 is flexibly connected with striker plate 1;
Wherein inflator mechanism 10 comprises piston 7, slide block 8, inflator chamber 9, connecting rod 6, inflator chamber 9 is fixed on the dish seat 5 of grinding roller, connecting rod 6 one end is flexibly connected with the support II 4 on striker plate 1 by pin, the other end is fixed on slide block 8, slide block 8 is fixed on piston 7, slide block 8 and piston 7 are arranged in inflator chamber 9, are provided with breather cheek valve 11 bottom inflator chamber 9;
In inflator mechanism 10, gas is pressed into by breather cheek valve 11, the air pressure that the inside is airtight, promote piston 7 to move, piston 7 is with movable slider 8 to move together, thus promotion connecting rod 6 moves, connecting rod 6 drives striker plate 1 to move up and down, and by forming different angles with horizontal plane, realizes the height automatically adjusting striker plate 1.
Described pin I 2 is provided with key 12, for steady pin I 2.
Described striker plate 1 is flexibly connected with plural inflator mechanism 10; Enable there are enough support forces during its work.
The utility model has following beneficial effect: in the closed chamber 13 of inflator mechanism 10, pass into gas by breather cheek valve 11, along with striker plate 1 weight changes, the air pressure of the inside changes by changing the volume of the inner confined space in inflator chamber 9, realizes automatic regulating function.When grinding machine just runs, striker plate 1 shifts piston 7 onto certain space position due to self gravitation, makes total power of outside equal the inside gas pressure; Along with the operation of machine, when abrasive material is deposited on striker plate 1, weight on striker plate 1 strengthens, the power that connecting rod 6 receives also strengthens, thus drives piston 7 to compress gas in closed chamber 13, and the gas volume of closed chamber 13 reduces, thus make connecting rod drive backgauge 1 plate to move downward, make striker plate 1 height reduction, when closed chamber 13 gives the pressure of piston equal with connecting rod effect, striker plate 1 height can not change again; When abrasive material produces wearing and tearing to striker plate 1, striker plate 1 self gravitation reduces, the power acting on piston is also little, air pressure inside closed chamber 13 reduces, volume increases, thus making connecting rod drive striker plate 1 to move upward, striker plate 1 is highly raised, and this motion process finally makes striker plate 1 remain unchanged at certain altitude.Striker plate 1 with abrasion of particles until when can not use, can by dismounting several bindiny mechanism just can simply replace, improve the operating efficiency of equipment, reduce maintenance cost.
