Description

Technical Field

[0001] The utility model relates to the technical field of dry ball mills, in particular to a concrete block dry ball mill. Background Art

[0002] Dry ball mill is one of the commonly used equipment in concrete material processing. Different from wet ball mill, dry ball mill does not need to add water, but directly puts concrete raw materials and abrasives into a rotating cylinder for grinding. This machine is usually used to crush and mix dry raw materials, such as cement clinker, gypsum and ore. Dry ball mill usually has higher production efficiency and is suitable for some concrete processing techniques that do not require wet treatment.

[0003] For example, the new lightweight concrete grinding equipment disclosed in the authorization announcement number CN215843341U comprises a ball mill housing, a driving device, a water cooling device, and a support frame. A rack is provided on the outer wall of one side of the ball mill housing. The driving device is meshed and connected with the ball mill housing to drive the ball mill housing to rotate. The water cooling device is arranged above the ball mill housing. The beneficial effects of adopting the above technical scheme are: cooling by water cooling, and at the same time, heat-conducting fins are arranged on the surface of the ball mill housing, which increases the heat dissipation surface area of ​​the ball mill housing and is beneficial to the heat dissipation of the ball mill.

[0004] The above device has a simple structure and reasonable design, can meet the needs of users, and has great promotion value;

[0005] Although the above patent can use a water cooling device to spray and cool the ball mill shell from above, when the ball mill shell rotates, the sprayed water will be sprayed on the upper surface of the shell and will be splashed to the outside by the centrifugal force of the rotating shell, which will cause a waste of water resources.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] 1. A concrete block dry ball mill is used in combination with a bracket, an arc-shaped baffle, a water pipe and a nozzle. The water pipe is sent into several nozzles at the bottom of the arc-shaped baffle, and then a water curtain is formed by spraying through the nozzle to cool the ball mill from above. When the ball mill is driven to rotate by a driving mechanism, the water curtain will swing in the same direction as the rotation direction of the ball mill, and will fall along the arc-shaped baffle after being blocked by the arc-shaped baffle. In this way, when spraying for cooling, the water curtain will not splash to the outside, thereby achieving the purpose of saving water resources.

When the transmission shaft rotates, the paddle arranged inside the water tank will rotate synchronously. When the paddle rotates, it stirs the water flowing back inside the water tank, which can drive the water flow, thereby accelerating the rapid volatilization of heat of the hot water after the return, making it easy to be recycled, thereby improving the cooling effect.
