As shown in fig. 1-3, the inner diameter of the splash-proof cover 2 is 3-4 times of the inner diameter of the discharge pipe 1, the dye splashes or the dye sprayed from the discharge pipe by compressed air in the dye-stripping cylinder 3 is mainly caused by the overlarge wind speed of the dye, the flow speed of the outlet of the splash-proof cover 2 is generally controlled to be 3.4-5.4 m/s, the wind speed range is three stages, and the wind power level is low, i.e. the dye does not splash or blow. The flow rate at the outlet of the splash shield 2 is calculated by the following flow rate equation:
wherein V1Is the maximum gas flow rate, V, in the discharge pipe 12The maximum flow speed V in the discharging pipe 1 is tested according to the maximum flow speed of the outlet of the splash eliminating cover 2, D is the inner diameter of the splash eliminating cover 2, D is the inner diameter of the discharging pipe 11Is 50m/s, and V2In the range of 3.4 to 5.4m/s, V is first added2Substituting the flow rate into the formula at 3.4m/s to obtain
Rounding to 4 times, and then adding V2Substituting the value into the formula of 5.4m/s to obtain
The integral is 3 times, so the inner diameter of the splash elimination cover 2 is 3-4 times of the inner diameter of the discharge pipe 1, the flow velocity of the splash elimination cover in the range is similar to three levels of wind power, and the splash and blow-off phenomena cannot be caused.
As shown in fig. 1-3, the fastening device 4 is a clamp assembly, the clamp assembly is composed of a clamp body 4-1, a bolt 4-2, a nut 4-3 and a flat pad 4-4, the clamp body 4-1 is a semicircular structure, the bolt 4-2, the nut 4-3 and the flat pad 4-4 are symmetrically arranged at two sides of the clamp body 4-1, and the clamp body 4-1 is fastened and connected with the fixed connection seat 5 through the bolt 4-2, the nut 4-3 and the flat pad 4-4, and the structure has the following advantages: the installation and the disassembly are convenient, and the operation is easy; the clamp component is convenient to select, and a clamp with a corresponding model can be selected according to different pipeline sizes; the fastening performance is safe and reliable.
As shown in figures 1-3, when the compressed air is used for purging the pipeline, the working principle is the same as that of the dyeing material conveying process, the structure can obviously reduce the wind speed of the compressed air entering the dyeing cylinder 3, prevent the air in the discharging pipe 1 from blowing the dyeing material in the dyeing cylinder 3, avoid the great waste of the dyeing material in the dyeing cylinder 3, improve the dyeing quality, save the dyeing material and reduce the pollution of the dyeing material to the production environment.
