Abstract

The utility model belongs to the field of a fluid pipeline and particularly relates to an improvement of a structure of an online fluid adding device. The online fluid adding device mainly comprises a main pipeline and a branch pipe which is arranged on the main pipeline and is communicated with the main pipeline, wherein the inner end of the branch pipe extends into the middle part inside the main pipeline and is provided with an inclined opening; and the inclined opening faces to a fluid flowing direction. The online fluid adding device has the advantages of low adding pressure and convenience for adding. Meanwhile, added matters are rapidly mixed with fluid at a high speed and the effects are good.

Description

The online adding set of a kind of fluid

Technical field

The utility model belongs to the architecture advances that the fluid line field particularly relates to the online adding set of a kind of fluid.

Background technique

In many industries such as papermaking, water treatments; Sometimes need one or more material on-line continuous be added in pipeline in the swiftly flowing another kind of material; Existing as shown in Figure 1 under the adding set, be on main pipe 2, to open a mouth to install an arm that is communicated with it 1 then, arm 1 the inner flushes with main pipe 2; Among the figure shown in the arrow E is that affix gets into the direction in the main pipe 2, and arrow H is the flow direction of high-velocity fluid in the main pipe 2.Mainly there is following defective through this arm 1 toward main pipe 2 interior interpolations continuously: 1. because main pipe 2 interior high-velocity fluids have higher pressure; The pressure that the pressure that props up tube fluid when adding in 2 from arm 1 toward main pipe just must be higher than main pipe 2 inner fluids just can add, and the interpolation difficulty is big; 2. the material that adds flows along tube wall easily, is not easy evenly to mix with main pipe 2 interior materials, and additive effect is poor.

Summary of the invention

The goal of the invention of the utility model is the defective to above-mentioned existence, provides the required pressure of a kind of interpolation little, adds easily the online adding set of the fluid that additive effect is good.

The utility model the technological scheme that will adopt be:

The online adding set of a kind of fluid comprises main pipe and is located on the main pipe and the arm that is communicated with it that the inner of arm extends the middle part in the main pipe, and arm the inner is provided with inclined open, and inclined open is towards fluid flow direction.

As preferably, arm vertically is located on the main pipe, is in inclined open in the main pipe by the inner oblique cutting ovalisation of arm.

As preferably, the center of the inclined open of ovalize is consistent with the center of main pipe.

Adopt the said online adding set of technique scheme, the inner of arm extends the middle part in the main pipe, and the material that adds flows with fluid rapidly and mixes, and additive effect is good.Arm the inner is provided with inclined open; Inclined open is towards fluid flow direction, and promptly the tube wall at the inner inclined open place of arm stops high-velocity fluid, and turbulent flow is walked around and formed to fluid herein; Make the inclined open place form low pressure like this; The convenient interpolation, the material rapid mixing of being convenient in the time of turbulent flow add is in high-velocity fluid, and is effective.

Fig. 3: the structural representation of arm among the embodiment.

Embodiment

Be to combine accompanying drawing 2 and Fig. 3 that the technological scheme of the utility model is done further to set forth in detail below.

The online adding set of a kind of fluid as shown in Figures 2 and 3 comprises main pipe 4 and is located at the arm 3 on the main pipe that the inner of arm 3 extends the middle part in the main pipe 4, and arm 3 the inners are provided with inclined open 31, and inclined open 31 is towards fluid flow direction.Be the flow direction of high-velocity fluid in the main pipe shown in the arrow B among Fig. 2, arrow A is that affix gets into the direction in the main pipe 4.When arm 3 vertically is located on the main pipe 4; Arrow A is vertical with arrow B, and the inclined open 31 that is in the main pipe 4 is that inclined open 31 is when fluid flow direction by the inner oblique elliptical openings that forms of cutting of arm; The tube wall at inclined open 31 places stops high-velocity fluid; Turbulent flow is walked around and formed to fluid herein, makes the inclined open place form low pressure like this, the convenient interpolation.

In addition, a kind of preferred mode on the basis of above-mentioned mode of execution is that the center of inclined open 31 of ovalize is consistent with the center of main pipe 4, makes affix all add the positive middle part of main pipe 4 inner fluid layers, and additive effect is good.

Claims (3)

1. the online adding set of fluid comprises main pipe and is located on the main pipe and the arm that is communicated with it, it is characterized in that the inner of arm extends the middle part in the main pipe, and arm the inner is provided with inclined open, and inclined open is towards fluid flow direction.

2. the online adding set of a kind of fluid according to claim 1 is characterized in that arm vertically is located on the main pipe, is in the interior inclined open of main pipe by the inner oblique cutting ovalisation of arm.

3. the online adding set of a kind of fluid according to claim 2 is characterized in that the center of inclined open of ovalize is consistent with the center of main pipe.
