Description

Technical Field

[0001] This utility model relates to the technical field of small ball mill equipment, and in particular to a rapid separation device for ball milling media and slurry. Background Technology

[0002] Zirconium balls are widely used grinding media in grinding processes. Typically, a certain proportion of zirconium balls of different diameters, the material to be ground, and a solvent are mixed in a specific ratio, placed in a nylon jar, and then placed on a ball mill frame. The mixture is rotated at a certain speed for a certain period, allowing the zirconium balls and the material to rub against each other thoroughly. Combined with the effect of the solvent, this ensures the material is thoroughly mixed and reaches the required particle size. Based on past experience, during discharge, the zirconium balls and the ground slurry are often poured into a sieve for filtration and washing. However, because the slurry has a certain viscosity, and the zirconium balls of different diameters are interlocked, cleaning becomes more difficult, leaving some slurry residue in the gaps between the zirconium balls. This results in slurry waste and economic losses for the company. Furthermore, this residual slurry may be carried into the next grinding process, contaminating the next batch of slurry, causing instability or even spoilage, and posing a risk to the company's product quality. Utility Model Content

[0003] In view of the problems existing in the prior art, the present invention aims to provide a rapid separation device for ball milling media and slurry, so as to ensure the output yield and the cleanliness of the zirconium balls after cleaning.

[0004] To achieve the above objectives, this utility model proposes a ball milling media and slurry separation device, including a support and a separation device mounted on the support. The separation device is rotatably connected to the support and is equipped with a drive component that can drive its rotation. The separation device includes an openable and closable cage, which includes steel plates at both ends and several steel rods connected between the two steel plates. Each steel rod forms a circle, and the gap between two adjacent steel rods is smaller than the diameter of the zirconium ball. A drain plate is provided below the cage, and the diameter of the drain hole in the drain plate does not exceed 1 mm. A tray is provided below the drain plate. Both the tray and the drain plate can be detachably fixed to the support.

[0005] In the above solution: the cage is a box structure, consisting of a box body and a lid. The box body and lid are connected and fixed at the four corners by U-shaped bolts. Each corner of the box body and lid has a lug, and each lug has a through hole for the U-shaped bolt to pass through. The U-shaped bolt has a pin hole. The two prongs of the U-shaped bolt pass through the corresponding two lugs and are locked in place by the pin. Removing the pin and then unfastening the U-shaped bolt allows the box body and lid to be separated.

[0006] In the above scheme: the cage body is connected to two rotating shafts on both sides, and the cage body is rotatably connected to the support through the two rotating shafts. The rotating shafts and the support are fixed by bearings, which makes the structure simple and easy to process.

[0007] In the above scheme: the driving component includes a rotary motor, and the output end of the rotary motor is connected to one of the rotating shafts via a belt drive. This enables automatic rotation of the entire cage, thereby achieving continuous production. To meet the separation requirements of slurries with different viscosities, the rotary motor needs to rotate at different speeds; therefore, a frequency converter can also be connected to the rotary motor to achieve this purpose.

[0008] In the above design, baffles are installed on both the front and rear sides of the cage, and the baffles are located near the slurry tray and fixed to the support. The baffles are made of stainless steel and can prevent the slurry from splashing randomly due to centrifugal force during the rotation of the cage.

[0009] In the above solution: An automatic spraying device is installed on the baffle. During the later stages of the rubbing process between the zircon balls, some slurry will adhere to the zircon balls and the steel rods and plates of the cage, making it difficult to drip off naturally. To ensure cleaning effectiveness, an automatic spraying device can be added to the baffle to spray water and rinse the cage as it rotates. For convenient daily use, a flexible hose with a nozzle can also be installed, allowing for more precise rinsing by hand and for routine cleaning of the equipment.

[0010] In the above scheme: the steel rod is a chrome-plated rod coated with polyurethane, and the steel plate is a chrome-plated stainless steel plate. The chrome plating layer can effectively isolate the metal substrate from the external environment, thereby reducing the risk of oxidation and corrosion. This is crucial for zirconium ball cleaning cages, as they may come into contact with corrosive substances or be in a humid environment during the cleaning process; the use of chrome-plated rods can significantly extend the service life of the equipment.

[0011] In the above scheme, the gap between two adjacent chrome-plated rods is 0.6 to 0.8 times the diameter of the zirconium ball. Considering that the zirconium ball will wear down during use and its particle size will gradually decrease, the specific gap between the two chrome-plated rods can be taken as 0.8 times the diameter of the zirconium ball, so as to prevent the zirconium ball from leaking out of the cage and mixing into the drain plate below.

[0012] In the above scheme: the bracket is provided with mounting holes for the corresponding drain plate and tray, the drain plate and tray are embedded in the corresponding mounting holes, and both are supported on the bracket by the outward folding edge of the edge.

[0013] The beneficial effects of this invention are as follows: 1. By designing a rotatable and openable non-sealed cage, when zirconium balls and grinding materials are poured into the cage, most of the slurry will flow out from the gaps in the cage and into the tray below. When the cage rotates, the zirconium balls inside can rub and wash each other to collect more slurry, thereby maximizing the amount of grinding material and reducing production losses. 2. During the grinding process, some zirconium balls will break into slag. A strainer is installed at the bottom of the cage to prevent this slag from mixing into the slurry. In summary, this invention can effectively ensure the output yield and the cleanliness of the zirconium balls after cleaning. Attached Figure Description

[0014] The above and / or additional aspects and advantages of this utility model will become apparent and readily understood from the description of the embodiments taken in conjunction with the following drawings, in which:

[0015] Figure 1 This is a schematic diagram of the structure of this utility model (without the baffle).

[0016] Figure 2 This is a side view of the present invention (with baffle).

[0017] Figure 3 This is a schematic diagram of the separation equipment. Detailed Implementation

[0018] like Figure 1 As shown in Figure 3, a ball milling media and slurry separation device mainly consists of a support 1 and a separation device mounted on the support 1.

[0019] The separation device is rotatably connected to the support 1, and is equipped with a drive unit 2 that can drive its rotation. The separation device includes an openable cage 3, which includes steel plates 31 at both ends and a number of steel bars 32 connected between the two steel plates 31. Each steel bar 32 forms a circle, and the gap between two adjacent steel bars 32 is smaller than the diameter of the zirconium ball.

[0020] Specifically, the gap between two adjacent chrome-plated rods is 0.6 to 0.8 times the diameter of the zirconium ball. Considering that the zirconium ball will wear down during use and its particle size will gradually decrease, the specific gap between the two chrome-plated rods can be 0.8 times the diameter of the zirconium ball to prevent the zirconium ball from leaking out of the cage 3 and mixing into the lower drain plate 4.

[0021] A drain plate 4 is provided below the cage body 3. The diameter of the drain hole of the drain plate 4 is no more than 1mm. A tray 5 is provided below the drain plate 4. Both the tray 5 and the drain plate 4 can be detached and fixed on the bracket 1.

[0022] Specifically, the bracket 1 has mounting holes for the corresponding drain plate 4 and tray 5. The drain plate 4 and tray 5 are embedded in the corresponding mounting holes and are supported on the bracket 1 by the outward folding edges.

[0023] The cage body 3 is a box-like structure, consisting of a box body and a lid. The box body and lid are connected and fixed at the four corners by U-shaped bolts 6. Each corner of the box body and lid has a lug 33, with a through hole for the U-shaped bolt 6 to pass through. The U-shaped bolt 6 has a pin hole. The two legs of the U-shaped bolt 6 pass through the corresponding two lugs 33 and are locked in place by the pin 7. Removing the pin 7 and unfastening the U-shaped bolt 6 allows the box body and lid to be separated.

[0024] The cage body 3 is connected to the left and right sides by rotating shafts 8. The cage body 3 is rotatably connected to the support 1 through the two rotating shafts 8. The rotating shafts 8 and the support 1 are fixed by bearings. The structure is simple and easy to process.

[0025] The drive unit 2 includes a rotary motor, the output of which is connected to one of the rotating shafts 8 via a belt 9. This enables automatic rotation of the entire cage 3, thus achieving continuous production. To meet the separation requirements of slurries with different viscosities, the rotary motor needs to rotate at different speeds; therefore, a frequency converter can also be connected to the rotary motor to achieve this purpose.

[0026] Vertical baffles 10 are provided on both the front and rear sides of the cage body 3. The baffles 10 are located near the slurry plate 4 and are fixed to the bracket 1. The baffles 10 are stainless steel baffles, which can prevent the slurry from splashing randomly due to centrifugal force during the rotation of the cage body 3.

[0027] An automatic spraying device (not shown in the figure) is installed on the baffle 10. During the later stages of the rubbing process between the zircon balls, some slurry will adhere to the zircon balls and the steel rods 32 and steel plates 31 of the cage 3, making it difficult to drip off naturally. To ensure cleaning effectiveness, an automatic spraying device can be added to the baffle to spray water and rinse the cage 3 as it rotates. For convenient daily use, a flexible hose with a nozzle can also be installed, allowing for more precise rinsing by hand and for routine cleaning of the equipment.

[0028] Steel bar 32 is a polyurethane-coated chrome-plated bar, and steel plate 31 is a chrome-plated stainless steel plate. The chrome plating effectively isolates the metal substrate from the external environment, thereby reducing the risk of oxidation and corrosion. This is crucial for zirconium ball cleaning cages, as they may come into contact with corrosive substances or be in a humid environment during the cleaning process; the use of chrome-plated bars can significantly extend the service life of the equipment.
