Embodiment Construction

[0035] The following is attached Figure 1-7 The application is described in further detail.

[0036] A pre-vacuum filter disclosed in the embodiment of the present application, see figure 1 , The pre-vacuum filter includes a cover body 1 and a bottle body 2 of a collection bottle. The cover body 1 is a disc-shaped structure, the bottom of the cover body 1 near the edge is provided with a thread groove extending in the circumferential direction, the bottle body 2 is a hollow cylindrical structure, and the cover body 1 is screwed to the top of the bottle body 2 through the thread groove .

[0037] see figure 1 , The middle part of the cover body 1 is pierced with an air inlet pipe 3, and the air inlet pipe 3 extends into the bottle body 2 for passing in gas. The cover body 1 is pierced with an air outlet pipe 4 near the edge. The air outlet pipe 4 does not extend into the bottle body 2. The cover body 1 is provided with an air outlet hole. The air outlet hole communicates w...

Abstract

The invention relates to the technical field of filtering equipment, in particular to a front vacuum filter, which comprises a cover body and a bottle body of a collecting bottle, wherein the cover body is in threaded connection with the bottle body, the cover body is provided with an air inlet pipe and an air outlet pipe, the peripheral side of the air inlet pipe is sleeved with a connecting pipe, and mounting columns are uniformly arranged on the peripheral side of the connecting pipe at intervals. The mounting columns are obliquely arranged downwards, connecting strips used for connecting the mounting columns are arranged on the sides, away from the connecting pipe, of the mounting columns, mounting spaces are formed between the adjacent mounting columns and the connecting strips, filtering layers are arranged in the mounting spaces, the connecting strips are provided with sliding assemblies, and the connecting strips slide in the bottle body through the sliding assemblies; the cover body is provided with a driving assembly used for driving the connecting pipe to rotate, a collecting groove used for collecting liquid is formed in the side, facing the mounting column, of the connecting strip, and a discharging groove communicated with the collecting groove and penetrating downwards is formed in the connecting strip. The effect of reducing the number of droplets contained in the air leaving the collection bottle is achieved.

Description

technical field [0001] The present application relates to the technical field of filtering equipment, in particular to a pre-vacuum filter. Background technique [0002] The pre-vacuum filter is a device that allows the gas mixed with liquid droplets to pass through the collecting bottle before entering the pump body, so that the liquid droplets in the gas condense on the wall of the collecting bottle to reduce the number of liquid droplets entering the pump body. [0003] At present, the Chinese utility model patent whose notification number is CN208018629U discloses a kind of laboratory shut-off bottle, which is made of a glass bottle, a bottle cap, a gas passage, a liquid passage, a shut-off pipe and a float. A bottle cap is installed at the bottle mouth of the glass bottle, and a trachea is installed on the bottle cap. One end of the two ends of the trachea forms an air inlet, and the other end forms an air outlet. There are two sockets on the lower part of the air pipe...
