Description

Steel ball grinding iron mud draining treatment device and method Technical Field The invention belongs to the technical field of steel ball grinding, and particularly relates to a steel ball grinding iron mud draining treatment device and method. Background In the production and manufacturing process of the steel ball, in order to improve the roundness of the steel ball, the steel ball needs to be ground, in order to prevent the surface of the steel ball from being burnt due to heat generated by grinding, the surface of the steel ball needs to be continuously flushed by sodium nitrite rust-proof water, most of the grinding iron mud is not easy to dissolve and is deposited at the bottom of a grinding fluid tank, when a worker cleans the grinding iron mud at the bottom of the grinding fluid tank, the grinding iron mud is shaped like mud in a pond at the moment, most of the grinding iron mud is dumped into a large iron mud tank by a small plate car, and when the iron mud tank is full of the iron mud, the grinding iron mud is dug into a carriage of a large truck by an excavator and is carried away. Because of the large water content of the ground iron sludge, leakage events often occur during transportation and are sometimes penalized by environmental protection departments. The device for recycling the calcium propionate filter mud disclosed in the Chinese patent No. 117531260A optimizes the setting of the device for recycling the calcium propionate filter mud, changes the traditional precipitation method, designs a single-layer filter screen to hold up the calcium propionate filter mud, and then carries out simple water filtration, and the single-layer filter screen can be used as a drying carrier, thereby improving the precipitation efficiency and being suitable for popularization and use. In the prior art, iron mud is generally placed on a cloth Bao Nazai for standing and filtering, however, when the cloth bag is directly placed on a flat screen, the contact area between the bottom of the cloth bag and the screen is larger, water in sludge needs to permeate the cloth bag and then is discharged from gaps between the cloth and the screen, but the self weight of the cloth bag can compact the bottom sludge, the cloth is tightly attached to the screen, a sealing layer is easily formed, so that water is difficult to quickly permeate to the outside of the cloth, even if exudation is likely to be accumulated between the cloth and the screen due to large contact area, the water cannot drop in time, and the draining efficiency is low.
