Abstract

The invention discloses an exhausting equipment, which comprises the following parts: rotary shaft, exhausting aggregate and exhausting head, wherein the rotary shaft possesses first shaft part and second shaft part with rotatable first shaft part corresponding to the second shaft part; the exhausting aggregate is set at the first shaft part of the rotary shaft; the exhaust head is connected with the exhaust aggregate; when the first shaft part rotates corresponding to the second shaft part, the exhausting aggregate also rotates to save traditional central valve, in order avoid oil gas reflux pollution due to the central valve; the exhausting aggregate is set at the first shaft part directly to reduces the distance between the exhausting aggregate and the exhausting-waiting element effectively, which improves the exhausting efficiency obviously.

Description

technical field [0001] The invention relates to an exhaust device, in particular to an exhaust device for a lamp tube. Background technique [0002] In the production process of the lamp tube, the exhaust equipment is one of the very important equipment, its main purpose is to heat the lamp tube, vacuumize, clean, fill the gas and seal the process. [0003] Among them, the vacuum system is one of the core systems of the exhaust equipment. Generally speaking, the vacuum pump (pump) of the vacuum system is arranged outside the main body of the exhaust equipment, and is connected between the vacuum pump and the exhaust head through a vacuum pipeline. The vacuum process of the lamp tube must be done step by step, so multiple vacuuming procedures are required. In order to make the lamp tube pass through the vacuuming procedures of each vacuum pump in sequence, a center valve (Center Valve) must be designed between the vacuum pump and the exhaust head. ), so that the lamp can be ...
