Description
Technical field
The utility model is related to flour mill apparatus field, and in particular to a kind of to be applied to the flour mill with large-scale cross section
The soft connection device of rectangular duct.
Background technology
Flour mill is widely used in the grinding of the mineral products material such as metallurgy, building materials, chemical industry, mine, when system works material and
Wind is blended in internal system flowing, current industry and conveyed more using rectangular duct, in rectangular duct junction user
Pipeline distance can be increased and can cause stream swirl by being rounded structure.In industry it is many using junction directly using one section of canvas,
The flexible materials such as rubber are coupled, with the attachment structure of many bolt presses flexible materials.These connected modes have the following disadvantages：
One is flexible material quick abrasion, and use time is short, changes frequent；Two be that flexible material two ends use many bolt presses, is changed
Trouble；Three be easy leakage powder.
The content of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provide a kind of simple in construction, abrasion
Small, replacing is convenient, the not flour mill rectangular duct of leakiness powder soft connection device.
What the technical solution of the utility model was realized in：
It is provided with a kind of soft connection device of flour mill rectangular duct, including rectangular duct, described rectangular duct
Flange one, flange one is sleeved on the end of rectangular duct and the end of rectangular duct extends into the inside of flange one, described
Flange one is welded on rectangular duct, and the side of flange one is provided with pipe flange, and described pipe flange is relative with flange one
Set, and pipe flange is identical with the internal diameter of flange one, is respectively provided with described pipe flange and the end circumference of flange one
There is flange flange, the cross sectional shape of flange flange is L-shaped, described pipe flange and the flange flange of the L-shaped of flange one are opened
Mouth is oppositely arranged, and flexible material, described soft material are provided with simultaneously on described pipe flange and the flange flange of flange one
Hoop component is provided with material, described hoop component compresses the flange flange that flexible material is close to flange one and pipe flange
On.
Described flexible material is canvas.
5 ㎜ are smaller than between described pipe flange and flange one.
The cross section of described rectangular duct is orthogonal rectangle or four angles are one kind in the rectangle of fillet.
Good effect of the present utility model is：The utility model is used for soft connection between flour mill rectangular duct, milling
The rectangular duct that machine is used, is directly connected to four sides and the phenomenon not pressed tightly occurs, the flange side of playing a part of is rounded, and is easy to compress
Conveyed in flour mill rectangular duct and contain un-cleared dust in compressed air, air, dust passes through with compressed air from pipeline,
Equipment has operation to shake, and the connection of this structure had both facilitated dismounting maintenance, again the propagation of barrier vibrations, and dust is to soft between pipeline
Abrasion is connected with, compressed air enters rectangular duct from pipe flange output, and canvas is wrapped in the method for pipe flange and flange one
On blue flange surface, with two hoop components compress canvas on pipe flange, the flange surface of flange one, play to rectangular duct it
Between the sealing that connects；Distance between regulating flange can significantly mitigate abrasion of the powder to canvas, not leak powder within 5mm；More
The canvas that anchor ear removes abrasion need to be only opened when changing, new canvas is wound and is compressed with anchor ear, reliable sealing is realized；Flange is dashed forward
The effect that genesis comes off laterally to spacing and limitation anchor ear when being wound to canvas.
Brief description of the drawings
Fig. 1 is main structure diagram of the present utility model.
Fig. 2 is the partial structurtes enlarged diagram at A in Fig. 1.
Fig. 3 is left view structural representation of the present utility model.
Embodiment
As shown in Figures 1 to 3, a kind of soft connection device of flour mill rectangular duct, including rectangular duct 5, rectangular duct 5
Cross section be orthogonal rectangle or four angles are to be connected with flange 1, method on one kind in the rectangle of fillet, rectangular duct 5
Orchid 1 is sleeved on the end of rectangular duct 5 and the end of rectangular duct 5 extends into the inside of flange 1, and flange 1 is welded
On rectangular duct, the side of flange 1 is to being connected to pipe flange 1, and pipe flange 1 is oppositely arranged with flange 1, and pipeline
Flange 1 is identical with the internal diameter of flange 1, and 5 ㎜, pipe flange 1 and flange are smaller than between pipe flange 1 and flange 1
Flange flange 6 is connected with one 4 end circumference, the cross sectional shape of flange flange 6 is L-shaped, pipe flange 1 and flange 1
The opening of flange flange of L-shaped be oppositely arranged, it is simultaneously wound on the flange flange of pipe flange 1 and flange 1 to have soft material
Material 2, flexible material is that hoop component 3 is connected with canvas, canvas, and hoop component 3 compresses canvas and is close to flange one and pipeline
On the flange flange of flange.
