Abstract

The utility model provides a buffer tank which comprises a tank body, a seal head, a feed inlet, a discharge port and an air bag. The tank body is connected with the seal head through an equipment flange. The feed inlet and the discharge port are arranged at the top of the seal head. The air bag is arranged in an inner cavity of the buffer tank and is connected with the seal head through a flange. The seal head is also provided with a balance port, wherein a valve of the balance port is normally open and the balance port is communicated to the atmosphere. The buffer tank has the beneficial effects that due to the adoption of the technical scheme, air flow in a pipeline is ensured stable and the buffer tank is beneficial to production safety and has the advantages that the buffer tank has simple structure, is convenient to maintain, has low processing cost and high safety coefficient and the like.

Description

A kind of knock out drum

Technical field

The utility model relates to a kind of knock out drum, the intermediate equipment that especially a kind of mesolow gas delivery process is used.

Background technique

The production of field of medicine and chemical technology need be carried out under the certain pressure environment usually; As produce the ethamine raw material that often will use in the medicine intermediate, directly enter in the retort after it comes out from compressed tanks usually and react, but there is a problem in this; Ethamine becomes gas by liquid state after compressed tanks is come out; Instantaneous pressure changes very greatly, and such pressure enters into retort, can cause certain influence to the working life and the production safety of retort.

Summary of the invention

The problem that the utility model will solve provides a kind of effectively knock out drum of compensator or trimmer pressure, and the outlet pressure that it can stabilizing gas makes the air-flow in the pipeline steady, is beneficial to production safety, especially is suitable in the conveying of mesolow gas.

For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of knock out drum comprises tank body, end socket, material feeding mouth, discharge port and air bag.Be connected through vessel flange between tank body and the end socket, material feeding mouth, discharge port are arranged on the end socket top, and air bag is arranged on the inner chamber of knock out drum, is connected through flange with end socket, and said end socket also is provided with a valve and often opens, and leads to the balance port of atmosphere.

The said material feeding mouth of the utility model is connected with tank body through convex surface formula welded flange with discharge port.

Air enters between air bag and the knock out drum through balance port, forms a pre-punching power.Behind the air bag when the bigger gas of pressure enters into jar through material feeding mouth in, pressure diminished when volume became big, after reaching balance with pre-punching power, from discharge port output, got into next link then, had guaranteed that system pressure is stable, production safety.Pre-punching power through air is come buffer gas pressure, and cost of production is low, and it is effective to release the pressure, and need not knock out drum is carried out tonifying Qi.

Be connected through vessel flange between the said end socket of the utility model and the can body.In case air bag is aging, perhaps gas leakage needs to change, and perhaps need check, keep in repair knock out drum, can open vessel flange, keeps in repair very easily.

The shape of the said end socket of the utility model can be hemisphere, ellipse, dish, ball crown type, conical shell or flat cover, preferred hemisphere or ellipse.Hemispherical head is comparatively desirable structural type, have stressed big, the advantage that is easy to make, ellipsoidal head is considered from intensity, structure and manufacture view, also is comparatively desirable selection.

Can also be provided with four leg formula bearings of symmetry mutually around the base of the said tank body of the utility model.Leg formula bearing has characteristics simple in structure, light and handy, easy for installation, and bigger operation and maintenance space is arranged below the tank body.

The described end socket of the utility model can also be provided with a spare interface, in case material feeding mouth or discharge port break down, can launch, and strengthens Security.

Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, guaranteed that the air-flow in the pipeline is steady, be beneficial to production safety, had simple in structurely, easy to maintenance, processing cost is low, the safety coefficient advantages of higher.

Embodiment

The feed component that this instance is selected for use is the ethamine gas that comes out from compressed tanks, feed pressure 0.3Mpa.

As shown in Figure 1, the utility model comprises tank body 1, end socket 7, material feeding mouth 2, discharge port 3, air bag 4.Be connected through vessel flange 6 between tank body 1 and the end socket 7, air bag 4 is arranged on the inner chamber of knock out drum, is connected through flange with end socket 7.The shape of institute's end socket 7 is hemispheres, and material feeding mouth 2, discharge port 3 are arranged on the top of end socket 7, and they are connected with end socket 7 through convex surface formula welded flange respectively, and the top of end socket 7 also is provided with a valve and often opens, and leads to balance port 5 and spare interface 9 of atmosphere.

Be provided with four leg formula bearings 8 of symmetry mutually around the base of tank body 1.

The working procedure of this instance: when ethamine gas when material feeding mouth 2 enters into air bag 4, it is big that volume becomes, pressure descends; And enter into the air balance between knock out drum and the air bag 4 through balance port 5 after; The ethamine gas pressure is reduced to 0.1Mpa, from discharge port 3 outputs, gets into retort.

More than the embodiment of the utility model is specified, but said content is merely the preferred embodiment of the utility model, can not be considered to be used to limit the practical range of the utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the utility model.
