Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

Examples

Referring to fig. 1-2, the present invention provides a technical solution: dichloromethane backward flow venting device, including body 1 and with 1 fixed connection's of body dustcoat 2, the inside of body 1 is equipped with and is the baffle 3 that leaks hopper-shaped, and the inner wall of body 1 is equipped with slide 4, and the inside of dustcoat 2 is equipped with mounting panel 5, is equipped with spring 8 between mounting panel 5 and the slide 4, and a plurality of is central symmetric distribution's through-hole 6 has been seted up on mounting panel 5's surface.

The scheme has the following working process;

in the preparation process of dichloromethane, during the period, dichloromethane mixed gas needs to be emptied and returned, when the mixed gas passes through the tube body 1, gas is collected, the gas pressure is increased, liquid in the gas flows into the preparation pipeline along the baffle 3, when the gas pressure reaches the pressure limit of the spring 8, the sliding plate 4 rises, the spring 8 is compressed, the sliding plate 4 and the tube body 1 slide relatively, the gas is discharged, after the gas pressure is reduced, the spring 8 rebounds, the spring 8 pushes the sliding plate 4 to continuously seal the tube body 1, the gas flow is ensured to be positioned in the tube body 1, the volatilization of the dichloromethane liquid in the gas is reduced, the gas flow is discharged along the through hole 6, in the process of continuously increasing the gas pressure, the sliding plate 4 and the spring 8 are continuously contracted and discharged, and the whole equipment.

According to the working process, the method can be known;

when the mixed gas passes through the pipe body 1, the gas is collected, the gas pressure is increased, the liquid in the gas flows into the preparation pipeline along the baffle 3, when the gas pressure reaches the pressure limit of the spring 8, the sliding plate 4 rises, the spring 8 compresses, the sliding plate 4 and the pipe body 1 slide relatively, the gas is discharged, after the gas pressure is reduced, the spring 8 rebounds, the spring 8 pushes the sliding plate 4 to continuously seal the pipe body 1, the gas flow is ensured to be positioned in the pipe body 1, the volatilization of dichloromethane liquid in the gas is reduced, the gas flow is discharged along the through hole 6, in the process that the gas pressure is continuously increased, the sliding plate 4 and the spring 8 are continuously contracted and discharged, the whole equipment is always in a working state, compared with the prior art, the emptying and the backflow are needed when dichloromethane is prepared, however, when the air is emptied, the gas and the liquid are mixed more closely, the gas and the liquid are, and cause the pollution to the environment, this scheme is sealed with body 1 through slide 4 and spring 8, and under the normal condition, when the gas-liquid mixture arrived slide 4 positions, the gas-liquid mixture stayed a period, and liquid separates because of gravity factor easily, and the subsequent evacuation is gone again, reduces the loss of liquid, and the harm of liquid to the environment reduces moreover.

Wherein, the top of baffle 3 is equipped with a plurality of baffle 10 that are central symmetry and distribute, and every baffle 10 all with baffle 3 fixed connection, specifically, when baffle 3 blocks the air mixture, the liquid molecule of air mixture is attached to on baffle 10, increases the backward flow volume of dichloromethane.

Wherein, spring 8's inside is equipped with telescopic link 9, and telescopic link 9's both ends respectively with slide 4 and 5 fixed connection of mounting panel, and is specific, when slide 4 is ejecting by the inside atmospheric pressure of body 1, slide 4's spring 8 compression, spring 8 compression make things convenient for spring 8's use more under telescopic link 9's guide, and then make things convenient for the unloading of equipment more.

Wherein, the top of mounting panel 5 is equipped with active carbon 11, and is concrete, and active carbon 11 passes through between to be fixed at the inner wall of dustcoat 2, and when gaseous the use, the air current filters partly through active carbon 11, and is environmental protection more.

Wherein, the top of dustcoat 2 is equipped with filter screen 7, and is concrete, and filter screen 7 can be dismantled with dustcoat 2 and be connected, and when the mist was emptied, the large granule in the gas was filtered by filter screen 7, but also can reduce the invasion of external dust, protective apparatus.

Wherein, the edge of baffle 3 is equipped with the chamfer, and is concrete, and when liquid in the gas got into in the baffle 3, the chamfer at 3 edges of baffle made things convenient for the entering of liquid more, made things convenient for the backward flow of equipment more.
