Description

Technical Field

[0001] The utility model belongs to the technical field of material digging tools and relates to a material digging tool used for a drum type ball mill. Background Art

[0002] In polyester production, the semi-matt production line needs to use a ball mill to fully grind the titanium dioxide-ethylene glycol suspension and grind the large particles into small particles that meet the requirements. The commonly used ball mill is a horizontal cylindrical type (drum ball mill), which has a stirrer made of multiple discs in series made of wear-resistant materials. The rotation of the disc drives the ceramic grinding beads to tumble, achieving a grinding effect. With the increase of usage time, the grinding beads and the inner barrel of the ball mill will wear out. At this time, the inside of the ball mill needs to be emptied and cleaned for inspection. The gap between the inner barrel and the disc of the ball mill is small, the density of the ball mill beads is large, and the number is large, so it is not easy to empty it.

[0003] Patent CN205392625U discloses a tool for scraping waste tailings of a ball mill, comprising a scraping handle, a scraping rod and a contoured scraping head, one end of the scraping handle is tilted upward, one end of the scraping rod is installed on the scraping handle, the cross-sectional shape of the contoured scraping head is trapezoidal, and the trapezoidal bottom surface of the contoured scraping head fits the chute of the waste tailings of the ball mill, and one side of the contoured scraping head is fixedly installed on the other end of the scraping rod; the scraping tool disclosed in the patent has a simple structure and is easy to use; however, the contoured scraping head designed in the patent is trapezoidal, which is not suitable for cleaning and scraping materials inside a horizontal cylindrical ball mill, and the scraping head is single-layered, the scraping efficiency is low, and it does not have a flushing function, so the working efficiency is not high in actual use.

[0004] Therefore, it is of great significance to study a new material removal tool suitable for horizontal cylindrical ball mill. Utility Model Content

[0005] The utility model aims to solve the problems existing in actual production and provides a material-digging tool for a drum-type ball mill.

[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] A material removal tool for a drum-type ball mill comprises an operating rod and a rear scraper, one end of the operating rod is vertically connected to the rear side of the rear scraper, and also comprises a front scraper and a connecting portion;

[0008] The front scraper and the rear scraper are both C-shaped plates arranged vertically and parallel to the left and right directions. The C-shaped plate is a part cut off from the annular plate. The inner diameter of the C-shaped plate is larger than the diameter of the stirring disc in the drum ball mill, and the outer diameter of the C-shaped plate is less than or equal to the inner diameter of the outer cylinder of the drum ball mill. Two scrapers are provided to increase the scraping amount.

[0009] The front scraper and the rear scraper are arranged at intervals in front and back, and the upper edges of the orthographic projections along the front and rear directions coincide with each other. The connecting part is located between the front scraper and the rear scraper, and the two ends are fixedly connected to the plate surfaces of the front scraper and the rear scraper, respectively, so that the probability of the scraper hanging on the mixing disc can be greatly reduced, and the operation is more convenient;

[0010] The operating rod is a hollow tube, and a through hole is opened on the rear scraper, and the through hole is connected to the hollow part of the operating rod;

[0011] The other end of the operating rod is connected to the high-pressure fluid delivery equipment, combining the material-removing tool with the flushing function, which can both remove materials and flush.

[0012] As the preferred technical solution:

[0013] In the above-mentioned material removal tool for a drum-type ball mill, the outer diameter of the C-shaped plate is equal to the inner diameter of the outer cylinder of the drum-type ball mill.

[0014] As described above, in the material unloading tool for a drum ball mill, the spacing between the front scraper and the rear scraper is greater than or equal to the spacing between any two adjacent stirring discs in the drum ball mill, and the spacing between the front scraper and the rear scraper is greater than the spacing between the stirring discs. During the material unloading process, the probability of the scraper getting caught on the stirring disc is reduced, and the operation is more convenient.

[0015] As described above, the material removal tool for a drum-type ball mill has two connecting parts which are arranged symmetrically on the left and right.

[0016] The material removal tool for a drum-type ball mill as described above further comprises a fastening nut and a locking nut;

[0017] The fastening nut is fixedly connected to the rear side surface of the rear scraper;

[0018] One end of the operating rod is provided with a threaded section;

[0019] The operating rod is fixedly connected with the fastening nut through the cooperation of the threaded section and the locking nut, and the fastening nut and the locking nut cooperate to form a double-nut fixation.

[0020] In the above-mentioned material-removing tool for a drum-type ball mill, the operating rod is a hollow cylindrical tube.

[0021] A material removal tool for a drum-type ball mill as described above, wherein the through hole comprises a main through hole and auxiliary through holes distributed annularly around the main through hole;

[0022] The main through hole is located on the central axis of the operating rod;

[0023] All through holes are located in the area where the rear scraper is connected to the operating rod.

[0024] A material removal tool for a drum-type ball mill as described above, the material removal tool also includes a connecting head and a telescopic hose;

[0025] The other end of the operating rod is connected to one end of the telescopic hose through a connector, and the other end of the telescopic hose is connected to the high-pressure fluid delivery device.

[0026] As described above, in the material removal tool for a drum-type ball mill, a valve is further connected between the operating rod and the telescopic hose. After water is passed through the telescopic hose, the valve can be used to control the water volume when cleaning the material removal.

[0027] Beneficial effects:

[0028] This material removal tool is specially designed for horizontal cylindrical ball mills, especially suitable for internal cleaning and material removal work, and has many beneficial effects:

[0029] (1) Increase the scraping amount: By adopting the double scraper design (front scraper and rear scraper), the scraping amount of a single cleaning is significantly increased, and the cleaning efficiency is improved;

[0030] (2) Reduce interference: The scraper is designed to be a fan-shaped ring with an inner diameter larger than the diameter of the stirring disc and an outer diameter smaller than (or equal to) the inner diameter of the outer cylinder, which effectively reduces the interference between the scraper and the stirring disc, ensuring smooth and safe operation. At the same time, the spacing between the scrapers is larger than the spacing between the stirring discs. The existence of the connection further reduces the risk of the scraper and the stirring disc colliding, making the operation more convenient.

[0031] (3) Combined flushing function: The operating rod is hollow in design and can be connected to high-pressure fluid delivery equipment to achieve the function of cleaning and flushing at the same time, effectively improving the cleaning effect. BRIEF DESCRIPTION OF THE DRAWINGS
