Abstract
The utility model provides a turbulent flow double cannula, this turbulent flow double cannula includes: the outer tube sets up just be located in the outer tube the interior sleeve pipe of outer tube axis one side, interior sleeve pipe go to court to one side of outer tube axis is provided with a plurality of edges the breach that interior sleeve pipe length direction arranged, the breach endotheca is intraductal be provided with with the setting of breach one -to -one and with the perpendicular aeroscopic plate of connecting of pipe wall of outer tube, the circular slab of aeroscopic plate for having the through -hole, interior sleeve pipe lies in the one end of outer tube import is connected with the oval plate washer that the slope set up. The beneficial effects of the utility model are that: double cannula through the setting has improved mixed effect gaseous and the ash material, and then has reduced the jam condition when transporting.
Description
Technical field
This utility model is related to the technical field of pneumatic ash handling, more particularly to a kind of turbulence double-pipe.
Background technology
Coal unit pneumatic ash handling induction system is a kind of pneumatic conveying process, from the fine coal that electric duster ash bucket falls
Ash, enters the transmitter of bottom, then through by air conveying mode, falling into by having an area of section, expansion joint, inlet valve
Flying dust is sent to the flyash of transmitter the grey storehouse specified by conveyance conduit.
In above-mentioned transportation, gas ash mixing is uneven, easily results in blockage, realizes that material is defeated using turbulence double-pipe
Central Zi Dong Cheongju are sent to block up.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, there is provided a kind of turbulence double-pipe.
This utility model is to be achieved through the following technical solutions：
This utility model provides a kind of turbulence double-pipe, and the turbulence double-pipe includes：Trocar sheath, is arranged on the overcoat
In pipe and positioned at the inner sleeve of the trocar sheath axis side, the side on the inner sleeve towards the trocar sheath axis is arranged
There are multiple breach along inner sleeve length direction arrangement；It is provided with the breach inner sleeve and corresponds with the breach
Arrange and the aeroscopic plate connected vertically with the tube wall of the trocar sheath, the aeroscopic plate is the circular slab with through hole；In described
Sleeve pipe is located at one end of the trocar sheath import and is connected with the oval plate washer being obliquely installed.
Preferably, on each guide plate the center of through hole breach corresponding with the guide plate along the trocar sheath axis side
To two ends line angle be in 90 degree.
Preferably, the two ends of the trocar sheath are respectively arranged with adpting flange.
The beneficial effects of the utility model are：The mixed effect of gas and ash material is improve by the double-jacket tube for arranging, is entered
And reduce the stopping state in transport.
Description of the drawings
Fig. 1 is the structural representation of the turbulence double-pipe that this utility model embodiment is provided.
Specific embodiment
In order that the purpose of this utility model, technical scheme and advantage become more apparent, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.It should be appreciated that specific embodiment described herein is only to explain
This utility model, is not used to limit this utility model.
Fig. 1 is referred to, Fig. 1 is the structural representation of the turbulence double-pipe that this utility model is provided.
This utility model embodiment provides a kind of turbulence double-pipe, and the turbulence double-pipe includes：Trocar sheath 1, is arranged on
In the trocar sheath 1 and positioned at the inner sleeve 2 of 1 axis side of the trocar sheath, towards the trocar sheath 1 on the inner sleeve 2
The side of axis is provided with multiple breach 5 along the arrangement of 2 length direction of the inner sleeve；It is provided with 5 inner sleeve 2 of the breach
Correspond with the breach 5 and arrange and the aeroscopic plate 4 connected vertically with the tube wall of the trocar sheath 1, the aeroscopic plate 4 is tool
There is the circular slab of through hole；The inner sleeve 2 is located at one end of 1 import of the trocar sheath and is connected with the oval plate washer 3 being obliquely installed.
In the above-described embodiments, the double-jacket tube by arranging improves the mixed effect of gas and ash material, when big pipeline is sent out
Raw plugging strength dispels material bolt from the breach of small pipeline and realizes automatic dredging, and then reduces the stopping state in transport.
The double-jacket tube that the present embodiment is provided is understood for convenience, which is carried out with reference to specific embodiment and accompanying drawing
Detailed description.
As shown in figure 1, Fig. 1 shows the structural representation of double flowing tube, in the present embodiment, double flowing tube includes an overcoat
Pipe 1, the two ends of the trocar sheath 1 are respectively arranged with adpting flange 6.Also include an inner sleeve 2 being sleeved in trocar sheath 1, tool
Body, the inner sleeve 2 is located at the side of 1 axis of trocar sheath, as shown in figure 1, and towards the one of 1 axis of trocar sheath on inner sleeve 2
Side offers multiple breach 5, and the breach 5 is used to ventilate, and multiple breach 5 are arranged along 2 length direction of inner sleeve, additionally, inner sleeve
It is closure that pipe 2 is located at one end of the import of trocar sheath 1, i.e., realize the closure to inner sleeve 2 by oval plate washer 3, and this is ellipse
Circle plate washer 3 is obliquely installed so that the import of trocar sheath 1 forms an opening greatly, internal little structure.Additionally, setting in inner sleeve 2
Put and 5 corresponding aeroscopic plate 4 of each breach, the aeroscopic plate 4 is the circular slab with through hole, specifically, as shown in figure 1, each
On guide plate, corresponding with the guide plate breach in the center of through hole 5 is in the line along the two ends of 1 axis direction of the trocar sheath
Angle is in 90 degree.
When specifically used, gas ash mixture enters outer tube 2 when there is plugging, and air-flow enters inner sleeve 2, when gas exists
When running in inner sleeve 2, a part of gas is blocked by deflector, enters into trocar sheath 1 from breach 5, and another part gas continues
Flowed after through hole, until entering into trocar sheath 1 from breach 5 after being blocked by oval plate washer 3.As seen from Figure 1, in ash material
When being transported to diverse location, there is the gas from the blowout of breach 5 to enter in trocar sheath 1, so as to improve gas with ash material
Mixed effect, realizes from dynamic Cheongju plugging functions, and then improves the transport effect of ash material.
By foregoing description as can be seen that the present embodiment improves the mixing effect of gas and ash material by the double-jacket tube for arranging
Really, so reduce transport when stopping state.
Preferred embodiment of the present utility model is these are only, it is not to limit this utility model, all in this practicality
Any modification, equivalent and improvement for being made within new spirit and principle etc., should be included in guarantor of the present utility model
Within the scope of shield.
