Problems solved by technology

The emulsion and large impurities sprayed by the conventional spraying device will have a strong impact on the filter paper, which is easy to break and damage the filter paper. On the one hand, it will directly reduce the filtering effect of the filter paper. On the other hand, the negative pressure cannot reach the set value and the filter paper will not move automatically.

Abstract

The invention relates to an emulsified liquid vacuum filter spray device, which comprises a filter box, a spraying pipe, a driving motor, a backflow pipe, a crawler belt and filter paper, wherein thecrawler belt is arranged in the filter box; the crawler belt is arranged on a driving roller and a tensioning device; the driving motor drives the driving roller to rotate; the filter paper is arranged at the inner side of the crawler belt; the spraying pipe is arranged at one end of the filter box; the spray pipe is provided with a spray device at one end of the filter box; the spray device is ofa cube structure. The special emulsified liquid vacuum filter spray device is designed, so that the emulsified liquid is uniformly dispersed and sprayed into the filter box; the impact of the emulsified liquid on the filter paper can be relieved; the impact of larger impurities on the filter paper can be reduced; the blockage of the emulsified liquid filter spraying device by impurities in the emulsified liquid can be avoided; the stable use of the emulsified liquid filter is finally realized; the filtering effect is ensured.

Description

technical field [0001] The invention relates to the field of emulsion vacuum filters, in particular to an emulsion vacuum filter spraying device. Background technique [0002] The filtration mechanism of the emulsion vacuum filter is mechanical screening, and the filter paper intercepts and separates the particulate impurities in the emulsion according to its pore size. The emulsion vacuum filter judges the degree of attachment of particles and impurities on the surface of the filter paper through negative pressure detection to determine whether it is necessary to walk the filter paper. The emulsion and large impurities sprayed by the conventional spraying device will have a strong impact on the filter paper, which is easy to break and damage the filter paper. On the one hand, it will directly reduce the filtering effect of the filter paper. On the other hand, the negative pressure cannot reach the set value and the filter paper will not move automatically. Contents of the...
