Problems solved by technology

[0002] At present, the recycling of waste generated in the production process of the limit-reinforced calcium silicate board or cement board industry in China is through Raymond grinding and then reused. The ground materials can only be used as fillers in general, and the utilization rate is low. , and during the grinding process of Raymond mill, the noise is loud and a large amount of fine powder cannot be effectively collected and repeated circulation in the system causes waste of power; and most of them use pumps with a power above (15kw) to transport the ground waste. During the process, not only the energy consumption is large but the pump is vulnerable, and it is inconvenient to replace and maintain the stone powder

Embodiment 1

[0037] Such as figure 1 and figure 2 As shown, a slurry grinding delivery system includes a wet ball mill 10, a slurry storage tank 20 and an air compressor 60, and the air compressor 60 transports the waste ground in the wet ball mill 10 to the slurry storage tank 20 via a pipeline 15 Inside, the wet ball mill 10 includes a cylinder 11, a bearing that carries the cylinder 11 and maintains its rotation. The bearings are arranged in the bearing housings 12 at both ends of the bracket 16. The cylinder 11 is driven to rotate through the driving device 30. The upper side of the cylinder 11 A water supply device 40 is provided; a feed port 13 is also included, and the feed port 13 is arranged at one end of the cylinder body 11, and the other end of the cylinder body 11 is provided with a discharge port 14, and the slurry storage tank 20 communicates with the discharge port 14 via a pipeline 15, The output end of the water supply device 40 communicates with the feed material 13 , ...

Embodiment 2

[0041] As shown in Figure 2, the structure of this embodiment is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that a cooling device 50 is provided at the lower end of the cylinder body 11, and the cooling device 50 includes a cooling liquid storage tank. 51, the cooling liquid storage tank 51 is set in the bracket 16, the lower end of the cylinder body 11 is provided with a cooling layer 52 that is adapted to the lower end surface of the cylinder body 11 and the gap is arranged on the lower end surface of the cylinder body 11, and the two ends of the cooling layer 52 are respectively connected with the cooling liquid The storage tank 51 is connected, and the lower end of the cooling liquid storage tank 51 is connected through a circulation pipe 53. The circulation pump 54 is also provided on the circulation pipe 53, and the cooling liquid storage tank 51 is filled with cooling liquid. In this way, in this application, t...

Embodiment 3

[0043] Such as figure 2 As shown, the structure of this embodiment is basically the same as that of Embodiment 1, and the similarities will not be repeated. The difference is that the belt transmission device includes a pulley 33 and a belt 34 that is sleeved on the pulley 33 and the cylinder body 11, and the pulley 33 It is coaxially fixedly connected with the power output shaft of the speed reducer 32, so, in the present application, the belt transmission device includes a pulley 33 and a belt 34 sleeved on the pulley 33 and the cylinder 11, and the power output of the pulley 33 and the speed reducer 32 The shafts are coaxially fixedly connected. Due to the pulling force of the belt 34, the load bearing capacity of the bearings at both ends of the cylinder 11 can be greatly reduced, thereby greatly reducing the friction force of the bearings, thereby reducing the heat generated by the friction of the bearings, and reducing the load of the servo motor. energy consumption.

Abstract

The invention relates to the technical field of plate recovering, in particular to a slurry grinding and conveying system. The slurry grinding and conveying system comprises a wet process ball mill, aslurry storing tank and an air compressor, the air compressor conveys ground waste in the wet process ball mill into the slurry storing tank through a pipe, and the wet process ball mill comprises abarrel and a bearing for bearing the barrel and maintaining the barrel to rotate; a waste treatment device comprises the wet process ball mill, the slurry storing tank and the air compressor, the waste is put into the wet process ball mill for water milling, high temperature is generated in the wet process ball mill, and a partial tobermorite crystal nucleus is better formed through silicon and calcium in the waste; meanwhile, the activity of the silicon and the calcium in the waste is improved, the later-period reacting is facilitated, the proportion of the waste in the formula is improved to5% from original 3%, and the performance of a plate is not influenced.
