Description

Technical Field

[0001] This utility model relates to the field of ball mill technology, and in particular to a ball mill for the reuse of waste culture media. Background Technology

[0002] In the production of silicon carbide ceramics, silicon carbide micropowder is processed through steps such as mixing into a slurry, spray granulation, pressing, and sintering to obtain the finished product. In the spray granulation process, the solid content is typically controlled at 50-55 wt%, and centrifugal atomization (8000-20000 rpm) is used to generate particles with a diameter of 10-100 μm. After sintering, approximately 35-45% waste substrate is produced. This waste substrate contains 45-60% silicon carbide micropowder, exhibiting high hardness (Mohs hardness 9.5), high temperature resistance (melting point 2700℃), and corrosion resistance.

[0003] Traditional processing methods often involve direct disposal, resulting in resource waste. Existing ball mills suffer from problems such as rapid liner wear, high energy consumption, and low grinding efficiency when grinding such high-hardness waste materials, and replacement is cumbersome. Furthermore, existing ball mills rely on a funnel-shaped discharge port and internal spiral device for forced discharge, resulting in low powder discharge efficiency. Utility Model Content

[0004] The purpose of this invention is to address the problems existing in the background technology by proposing a ball mill for the reuse of waste culture media.

[0005] The technical solution of this utility model is: a ball mill for recycling waste culture medium, including a frame, and an adjustment mechanism for adjusting its inclination is provided on the frame;

[0006] The cylinder has end caps A and B at its two ends. The cylinder is rotatably connected to the frame through end caps A and B.

Several sets of brackets are provided on the cylinder. Each bolt is threadedly connected to the bracket on the corresponding side. The bolt shank penetrates the outer wall of the cylinder and is inserted into the positioning groove on the corresponding side. The outer diameter of the bolt shank is the same as the inner diameter of the positioning groove.

[0013] Preferably, the end cap B has several discharge holes arranged in a ring array around its axis, and each discharge hole has a filter screen installed in it, with the concave surface of the filter screen having the same curvature as the concave surface of the end cap B.

The use of silicon carbide liners provides higher wear resistance than traditional polyurethane liners and ordinary manganese steel liners, with a lifespan exceeding 8000 hours. Furthermore, the liner uses a transverse insertion and positioning component, improving liner replacement efficiency. Additionally, this invention replaces the traditional flared discharge structure with a discharge hole combined with an annular cover, improving powder output efficiency. This structure is particularly suitable for continuous feeding and discharging. Attached Figure Description

In operation, the hydraulic cylinder drives the slide 4 to slide along the groove 31. End caps A12 and B14 are respectively provided at both ends of the cylinder 7. Both end caps A12 and B14 are connected to the cylinder 7 by flanges and bolts. The cylinder 7 is rotatably connected to the frame 1 through end caps A12 and B14. An inlet pipe 13 communicating with the interior of the cylinder 7 is provided on end cap A12, and an outlet pipe 17 communicating with the interior of the cylinder 7 is provided on end cap B14. Several discharge holes 141 are arranged in a circular array around its axis on end cap B14. Each discharge hole 141... A filter screen 15 is installed inside each hole 141. The concave surface of the filter screen 15 has the same curvature as the concave surface of the end cover B14. An annular cover 16, which rotates coaxially with the end cover B14, is fitted around the end cover B14. The annular cover 16 is fixedly connected to the frame 1. The inlet of the annular cover 16 covers the outside of each discharge hole 141. An outlet hole communicating with the inner cavity of the annular cover 16 is provided at its bottom. The discharge pipe 17 is connected to the annular cover 16, and the input end of the discharge pipe 17 is connected to the discharge hole. Several T-shaped grooves 71 are arranged in a ring array around the axis on the inner wall of the cylinder 7. There are multiple liners 10. The liners 10 are made of silicon carbide. T-shaped plates 11 are provided on the liners 10. The liners 10 are made of silicon carbide material. The T-shaped plates 11 are inserted into the T-shaped grooves 71 on the corresponding side and are slidably connected to their inner walls. A positioning assembly is mounted on the cylinder 7. In operation, the positioning assembly restricts the T-shaped plate 11 from sliding along the length of the T-groove 71. The positioning assembly includes multiple bolts 9.

[0027] In this embodiment, if the liner 10 is damaged, the end caps A12 and B14 are separated from the cylinder 7, the cylinder 7 is then removed, the bolt 9 corresponding to the liner 10 is rotated to disengage the stud from the positioning groove 111, and then the liner 10 is pushed along the axial direction of the cylinder 7 to remove it. After replacing the liner 10 in the same way, the stud on the bolt is then inserted into the positioning groove 111 of the new liner 10. After the equipment is reinstalled, the motor is started, and the motor drives the cylinder 7 to rotate. The raw materials, high-alumina ceramic balls and steel balls are added into the cylinder 7 along the feed pipe 13 in a ratio of 1:2. The raw materials collide with the balls and are ground into powder. The fine powder gradually moves towards the discharge hole 141 under the guidance of the inclined cylinder 7. The powder that meets the particle size requirement enters the annular cover 16 along the discharge hole 141 and is discharged from the discharge pipe 17. If the powder discharge efficiency is low or the powder discharge volume is small at this time, it is necessary to adjust the inclination of the cylinder 7. During operation, the hydraulic cylinder is started, and the hydraulic cylinder drives the slide 4 to slide along the direction of the inclined groove 31, thereby changing the distance between the support wheel B5 and the bottom plate of the frame 1, thereby achieving the purpose of adjusting the inclination of the cylinder 7.
