A dust filter for the front vacuum pump of a laminator

Abstract

The invention discloses a dust filter for a front-stage vacuum pump of a laminator, comprising a sealed filter box, the filter box is filled with vacuum oil, an air inlet is opened on one side of the top of the filter box, and an air outlet is opened on the other side , an intake pipe is installed at the air inlet, the distance between the end face of the intake pipe in the filter box and the vacuum oil level is 5-10mm, and the side of the intake pipe outside the filter box is connected with aeration The end of the aeration pipe away from the air inlet pipe horizontally extends into the filter box from the lower part of the filter box, the top of the aeration pipe extending into the filter box is evenly opened with several aeration holes, and an outlet pipe is installed at the air outlet , one end of the air outlet pipe is connected with a filter device, the other end is located in the filter box, and the distance between the end face of the air outlet pipe in the filter box and the vacuum oil level is 45-50mm. The invention is a vacuum pump intake pretreatment device, which can effectively filter dust and particles in the intake air and effectively prolong the service life of the vacuum pump.

Description

technical field [0001] The invention belongs to the technical field of vacuum pump air intake filtration, and in particular relates to a dust filter for a front-stage vacuum pump of a laminator. Background technique [0002] The laminator is widely used in the solar photovoltaic industry, and the vacuum pump as the front-end equipment of the laminator is essential. In the working process of the solar photovoltaic industry, due to the existence of more dust particles, the vacuum pump will accelerate the wear of the parts in the pump cavity after inhalation, the vacuum degree will drop, the vacuum pump oil will be polluted, etc., and even the vacuum pump will lock up in severe cases. extreme phenomenon, resulting in short service life of vacuum pumps used in the solar photovoltaic industry and high replacement frequency of vacuum pumps, resulting in higher costs for the entire industry. Therefore, a solution for dust removal and filtration at the intake end of the vacuum pump...
