Abstract
The utility model relates to a circulating barrel device of a stirring mill. The circulating barrel device comprises a barrel body, wherein the barrel body is provided with a discharge hole and a feeding hole, a stirring device is arranged in the barrel body, a motor is connected with a speed reducer in the stirring device, the motor and the speed reducer are arranged at the top part of the barrel body by a support, a stirring shaft is connected with the speed reducer, a plurality of stirring blades are arranged on the stirring shaft, and a scraper plate is arranged below the stirring blade at the bottom. According to the circulating barrel device of the stirring mill, sediments at the bottom of the barrel body are scraped by the scraper plate which is additionally arranged, so that the grinding unevenness is avoided; furthermore, the bottom of the barrel is designed to be in conical shape, so that the sediments are further reduced; besides, a variable frequency motor is adopted to reduce the starting load, and the motor is prevented from being burned out due to the increase of the area of the stirring blades.
Description
Technical field
Stirring mill in the preparation of the utility model phosphoric acid iron lithium battery, particularly a kind of mill circulation barrel device that stirs.
Background technology
Existing LiFePO4 LiFePO
4production technology, is recycling after raw material mixing, sintering to be stirred to mill grind, and in process of lapping, raw material slurry circulates in circulation barrel, and the problem of existence is that raw material slurry is easily deposited in the bottom of staving, causes grinding inhomogeneous.In prior art, there is the precipitation of 3 ~ 5mm in circulation barrel bottom.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of mill circulation barrel device that stirs, and can avoid circulation barrel bottom precipitation, to guarantee that raw material slurry evenly grinds.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of mill circulation barrel device that stirs, comprise staving, staving is provided with discharge gate and charging aperture, is provided with agitating device in staving, in described agitating device, motor is connected with decelerator, and motor and decelerator are arranged on the top of staving by support, and shaft is connected with decelerator, shaft is provided with multiple paddles, and the paddle below that is positioned at bottom is provided with scraper plate.
Described staving bottom is taper, and described scraper plate is in tilted layout accordingly, to adapt with staving bottom shape.
Described scraper plate material is rubber.
Discharge gate is positioned at the bottom of staving, and charging aperture is positioned at the top of staving, and discharge gate is connected with circulating pump by pipeline with charging aperture.
The position of discharge gate is also provided with triple valve.
Described motor is variable-frequency motor.
Through carefully analyzing, cause the reason of precipitation to be, the rotating speed of circulation barrel paddle is too low, and raw material slurry can not be stirred leaf and drive fully, thus the precipitation of causing.But the rotating speed that improves paddle, due to centrifugal phenomenon, can affect the capacity of circulation barrel, easily produces the problem of flash.
The one that the utility model provides stirs mill circulation barrel device, by the scraper plate of setting up, the precipitation material of staving bottom is swept by scraper plate, thereby avoids occurring grinding inhomogeneous phenomenon.Further, taper is arranged to in staving bottom, has further reduced precipitation.Further, adopt variable-frequency motor, to reduce starting load, avoided burning out motor because the area of paddle increases.
Brief description of the drawings
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is overall structure schematic diagram of the present utility model.
In figure: motor 1, decelerator 2, support 3, shaft 4, staving 5, paddle 6, scraper plate 7, discharge gate 8, circulating pump 9, triple valve 10, charging aperture 11.
Detailed description of the invention
In Fig. 1, a kind of mill circulation barrel device that stirs, comprises staving 5, and staving 5 is provided with discharge gate 8 and charging aperture 11, and discharge gate 8 is positioned at the bottom of staving 5, and charging aperture 11 is positioned at the top of staving 5, and discharge gate 8 is connected with circulating pump 9 by pipeline with charging aperture 11.The position of discharge gate 8 is also provided with triple valve 10.Drive the circulation of raw slurry by circulating pump 9.Grind completely, switch three-way valve 10, discharges raw slurry.
In staving 5, be provided with agitating device, in described agitating device, motor 1 is connected with decelerator 2, motor 1 and decelerator 2 are arranged on the top of staving 5 by support 3, shaft 4 is connected with decelerator 2, and shaft 4 is provided with multiple paddles 6, and paddle 6 belows that are positioned at bottom are provided with scraper plate 7.By the scraper plate arranging, the raw material that is deposited in staving 5 bottoms can be swept,
In the scheme of optimizing, described staving 5 bottoms are taper, and described scraper plate 7 is in tilted layout accordingly, to adapt with staving 5 bottom shapes.Staving 5 bottoms are set to taper, have strengthened the mobility of raw slurry, coordinate scraper plate, can better avoid precipitation.Preferably, the gap of distance from bottom staving 5 bottoms of scraper plate 7 is as much as possible little, for example, be less than 1mm, but also will avoid and staving 5 bottom frictions, in order to avoid affect the purity of raw slurry.
Preferably, described scraper plate 7 materials are rubber.
In the scheme of optimizing, described motor is variable-frequency motor.Because the structure of scraper plate 7 has increased the area of paddle 6, therefore also phase strain is large for staring torque, and because raw slurry is dense thick, easily motor damage, by adopting variable-frequency motor to reduce toggle speed, thereby avoids motor to be burnt.
