Abstract

The invention discloses a continuous vacuum defoaming device. The device comprises a seal head 1, a gas inlet 102, a material inlet 103, a gas exhaust port 104, a barrel body 2, a material outlet 201,a sight glass 105, a vacuum gauge 101 and a machine rack 201, and is characterized in that baffle blocks 203 are fixed to both the upper half segment and the lower half segment of the interior of thebarrel body, a screen mesh 4 is placed on the upper baffle block, an oval flow guiding body 3 is connected to the screen mesh, a pore plate 6 is placed on the lower baffle block in the barrel body, several to tens of umbrella-shaped screen meshes 5 with the convex surfaces upward are stacked on the pore plate, the material outlet end of the material inlet is in an umbrella shape, and a certain gap is maintained between the material outlet end of the material inlet and the surface of the oval flow guiding body. The gap between the material outlet end of the material inlet and the surface of the oval flow guiding body is 1-10 mm. The pore diameter of the pore plate is 0.5-10 mm. The purposes are completely achieved that the continuous vacuum defoaming device is simple in structure, flexibleand convenient, convenient to clean, high in defoaming efficiency, low in vacuum requirement and unlikely to cause waste.

Description

technical field [0001] The invention relates to a vacuum device, in particular to a continuous vacuum degassing device. Background technique [0002] As we all know, defoaming is of paramount importance in the chemical industry. The defoaming quality and its effect directly determine the smoothness of production and the quality of products. In the fine chemical industry, many surfactants, inks, coatings and other products need to be defoamed, and in the chemical fiber industry, defoaming is also a necessary process. Especially in the field of man-made fibers. In the traditional viscose fiber production process, the static degassing method is generally used for vacuum degassing. However, this is too long and time-consuming, requiring nearly 30 hours, which is very unfavorable for university production. In the later period, some manufacturers introduced continuous defoaming devices, generally using thin-film method, trickle method, and centrifugation method. But efficienc...
