However, the dust and noise generated when the ball mill grinds the substrate glass causes pollution to the current working environment. Utility Model Content

[0017] Reference Figures 1 to 3 As shown, this utility model provides a ball mill for substrate glass, including: a ball mill body 1 and a hopper 5, wherein the hopper 5 is provided at the right end of the ball mill body 1.

[0018] The outer surface of the ball mill body 1 is screwed with a heat recovery cover plate 2. The inner side of the heat recovery cover plate 2 is in contact with the ball mill body 1 through a heat conduction plate 6. A liquid storage chamber 23 is opened on the inner side of the heat recovery cover plate 2. The outer end face of the liquid storage chamber 23 is wrapped with a heat insulation rock wool board 24. The left and right sides of the ball mill body 1 are respectively connected to a first dust collection pipe 31 and a second dust collection pipe 32. The other end of the first dust collection pipe 31 and the second dust collection pipe 32 is connected to a pulse dust collector 3. The right side of the pulse dust collector 3 is connected to a fan 34 through a connecting pipe 33.

[0019] First, the substrate glass is fed into the inner side of the ball mill body 1 through the hopper 5 and the dust collector screw feeder 51. After grinding, it is discharged from the discharge pipe 15. The dust generated during grinding is sent into the pulse dust collector 3 by the first dust collection pipe 31 and the second dust collection pipe 32. When the heat generated during grinding is dissipated outward, it is conducted through the heat conduction plate 6 to the liquid storage chamber 23 of the heat recovery cover plate 2, and heat exchange occurs with the liquid in the liquid storage chamber 23, which facilitates the recovery of heat energy and reduces noise and dust pollution.

[0020] In this embodiment, a discharge pipe 15 is installed at the left end of the ball mill body 1. A screw conveyor 12 is connected to the left side of the discharge pipe 15 via a guide bin 11. A first dust collection pipe 31 is connected to the upper end of the guide bin 11. A feed pipe 14 is installed at the right end of the ball mill body 1. A hopper 5 is connected to the right side of the feed pipe 14 via a dust collector screw feeder 51. A second dust collection pipe 32 is connected to the upper end of the feed pipe 14. A large gear 13 is installed on the right side shell surface of the ball mill body 1; and a heat recovery cover plate 2 is fixed at the left end of the large gear 13. A high-pressure air back-blowing mechanism 4 is installed on the right side of the pulse dust collector 3.

[0021] In a preferred embodiment, the ball mill body 1 relies on the friction between the mill liner and the grinding media, and the centrifugal force generated during mill rotation, to keep them tightly against the inner wall of the cylinder for rotation and lifting. When the mill speed reaches a certain level, the grinding media and material deflect in the direction of mill rotation, maintaining their upward movement along a concentric circular trajectory. When the surface layer of grinding media exceeds the angle of repose, it naturally falls, then falls layer by layer from the outside in, repeating the cycle. At this point, the material is crushed by the rolling motion of the grinding media, which crushes and grinds the broken glass. A grinding head screen is installed at the outlet end of the ball mill body 1 to effectively isolate any broken grinding balls mixed in with the raw material. The large gear 13 is used to connect to an external motor gear transmission mechanism, thereby rotating the ball mill body 1 and causing the rotating alumina grinding balls on the inner side to grind the substrate glass. The dust collection pipe draws the dust into the pulse dust collector 3, where several internal cloth bags adsorb the glass powder. When the dust is adsorbed to a certain extent on the inner surface of the cloth bags, the high-pressure air back-blowing mechanism 7 blows and shakes the dust into the dust collection box at the bottom of the pulse dust collector 3. The dust in the dust collection box can be loaded into ton bags by a screw feeder and sent to the furnace for recycling.

[0022] In this embodiment, the heat recovery cover plate 2 is symmetrically screwed onto the outer surface of the ball mill body 1, and a heat-conducting plate 6 is welded to the inner side of the heat recovery cover plate 2. A liquid guide pipe 22 is provided in the middle of the outer surface of the heat recovery cover plate 2; and the liquid guide pipe 22 is connected to the liquid storage chamber 23, and a control valve 21 is installed on the surface of the liquid guide pipe 22. A temperature sensor is embedded in the front surface of the heat recovery cover plate 2, and the liquid storage chamber 23 is semi-annular.

[0023] In a preferred embodiment, the heat-conducting plate 6 directs the heat generated during the operation of the ball mill body 1 to the liquid storage chamber 23, allowing heat exchange between the heat and the temperature inside the liquid storage chamber 23, reducing heat loss and preventing the high temperature of the gas drawn into the dust collection pipe from affecting the normal operation of the pulse dust collector 3. The liquid in the liquid storage chamber 23 and the insulating rock wool board 24 inside the heat recovery cover plate 2 provide heat preservation and sound insulation, reducing noise pollution.

[0024] This utility model of a substrate glass ball mill can effectively solve the problem of dust and noise pollution caused by ball mills grinding substrate glass, prevent dust generated during substrate glass grinding from spreading into the external environment, realize the dust removal and noise reduction functions of the ball mill, reduce heat loss and noise pollution, improve the environmental friendliness of the ball mill, and is suitable for substrate glass ball mills.
