Embodiment 1

A kind of steel band production grinding stock tank, structure such as Fig. 1, including groove body 1, groove body 1 are set along the traffic direction of steel band 2 It sets, groove body is for containing grinding slurry.Groove body 1 is equipped with front guide roll 3 along the input end of steel band, and front guide roll 3 uses plain roller, to steel Band plays guiding role.Pressure roller 4 is equipped in groove body 1, applicator roll can be used in pressure roller.It is equipped on groove body along the rear of pressure roller and scrapes crutch 5.When operation, steel band is bypassed along the top of front guide roll, then is bypassed along the lower part of pressure roller 4, is eventually passed through and is scraped crutch, into subsequent work Sequence.Steel band is immersed in grinding slurry when by pressure roller lower part, is realized in steel strip surface pasting.It is above-mentioned leading in order to meet Roller 3, pressure roller 4 and the setting for scraping crutch 5, groove body 1 should have suitable length.Referring to Fig. 2, this programme emphasis is to scraping crutch Structure improves, and improved crutch of scraping includes column 501, and vertically disposed 502 He of upper squeegee is fixed on column 501 Lower squeegee 503.Conventional plastic plate can be used in upper squeegee 502 and lower squeegee 503, and two sides are connect with column 501, tool Frame can be arranged in the two sides of plastic plate in body, and frame is bolt-connected on column, replacement easy to disassemble.Upper squeegee It is installed with gap between 502 and lower squeegee 503, which runs through for steel band.Slurry is scraped under in the lower edge of upper squeegee 502 Working position of the upper edge of plate 503 as blade coating slurry, in steel band operation, pulp layer that steel band upper and lower surface is attached into Row drawout.

Steel band after mill base slurry, starch by one layered material of upper surface accumulation of thick, and lower surface is due to gravity, absorption Slurry it is less.And when by squeegee, steel band lower surface is easy to generate extruding, therefore steel band lower surface with lower squeegee It tends not to form the wash coat for requiring thickness.And upper surface by squeegee blade coating after thickness it is still larger, although not Following process quality can be impacted, but will cause the waste of grinding slurry.

In view of the above-mentioned problems, this programme is equipped with upper bending section 504, upper 504 direction of bending section in the lower end of upper squeegee 502 In front of groove body, the upper end of lower squeegee 503 is equipped with lower bending section 505, and lower bending section 505 is towards groove body rear.Specifically, bending Section is with the angle of squeegee at 120 degree or so.The structure scrapes crutch when carrying out slurry blade coating to steel band, and upper bending section is to steel The blade coating angle of belt surface is obtuse angle, can reduce slurry residual volume, and lower bending section is sharp to the blade coating angle of steel strip surface Angle can increase slurry residual volume.Said effect can make the coating layer thickness of steel band upper and lower surface tend to be uniform.

For the improvement of above scheme, upper bending section 504 and lower bending section 505 are arc, curved bend tune nature mistake It crosses, is not easily broken damage.

On the basis of above scheme, as a further improvement, upper squeegee 504 is equipped with upper hot-air mouth 506, upper hot wind Mouth 506 is located at the rear side of upper squeegee；Lower squeegee 505 is equipped with lower hot-air mouth 507, and lower hot-air mouth 507 is located at lower squeegee Front side；Upper hot-air mouth 506 and lower hot-air mouth 507 are towards the gap between upper squeegee and lower squeegee, that is, towards steel The surface of band.Upper hot-air mouth and lower hot-air mouth are flat air outlet, and air outlet is connected by air supply tube and hot blast feeding system It connects.The purpose that up-and-down hot wind mouth is arranged is heated to the wash coat of steel strip surface, is accelerated moisture evaporation, can be increased pasting In the adsorption strength of steel strip surface.

In addition, this programme makes further improvement aiming at the problem that grinding stock tank slurry splashing when carrying out pasting operation, Referring to Fig.1, it is equipped with rear baffle 6 along the outlet end of steel band in groove body 1, the top of rear baffle 6 is equipped with rear deflector roll 7.Steel band is passing through After scraping crutch 5, the top along rear deflector roll 7 is bypassed.When due to pressure roller rotation, and when scraping crutch and scraping slurry, slurry mainly towards It splashes at rear.Therefore setting rear baffle 6 can effectively block the slurry of splashing.Rear baffle 6 can be fixedly connected on groove body 1 Cell wall on.

To further prevent slurry to splash along two sides, on the basis of above scheme, the present embodiment is set in the two sides of groove body 1 There is side baffle 8, the height of side baffle 8 is not less than the height of rear deflector roll 7.

As improvement project, side baffle 8 and 1 two sides of groove body are to insert connection.It, specifically can be at the bottom of side baffle 8 referring to Fig. 3 Jack 101 is arranged in the two sides of groove body 1, convenient for the dismounting of side baffle in portion's Fixed latches 801.

As improvement project, the top for scraping crutch 5 is equipped with cover board, and cover board includes front shroud 9 and back shroud 10, front shroud and Back shroud is hinged at the top of crutch 5 with scraping, that is, hinged with the column 501 of scraping crutch, and front shroud 9 and back shroud 10 Width is not less than the width of groove body.In conjunction with above scheme, after mounting, in conjunction with rear baffle, front is more than pressure to side baffle 8 at rear portion Roller 4.After front shroud 9 and back shroud 10 are opened, the top of side baffle 8 can be relied on.Rear baffle 6, side baffle 8 and cover board can A closed chamber is constituted to enclose, plays the role of good block to the slurry of splashing.And side baffle 8 and cover board can be opened, The maintenance to blade holder 5 and pressure roller 4 is not influenced.

As improvement project, referring to Fig. 4, the roll surface of front guide roll 3 and rear deflector roll 7 is equipped with multiple guide grooves 11.Guide groove 11 Width it is corresponding with the width of single steel band, steel band is wound around in guide groove 11.In this way, can be applied simultaneously to a plurality of steel band Starch operation.

This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but As long as all by the protection of Patent Law in the scope of the claims of the utility model.
