Embodiment

With reference to the accompanying drawings and examples, specific embodiment of the present utility model is described in further detail.Below Embodiment is used to illustrate the utility model, but is not limited to the scope of the utility model.

, it is necessary to illustrate in description of the present utility model, unless otherwise clearly defined and limited, term " connection " It should be interpreted broadly, for example, it may be being fixedly connected or being detachably connected, or be integrally connected；It can be direct phase Even, can also be indirectly connected by intermediary.For the ordinary skill in the art, on being understood with concrete condition State concrete meaning of the term in the utility model.

With reference to shown in Fig. 1 and Fig. 2, a kind of Pneumatic conveying pipeline that the utility model embodiment provides, available for conveying stone The powder granules 3 such as limestone flour, pelletizing powder, sintering plant head ash and blast furnace ash, the Pneumatic conveying pipeline include conveying pipeline 1 and set Inner tube 2 in conveying pipeline 1, inner tube 2 may be provided at the top of conveying pipeline 1, not interfere with the defeated of material in conveying pipeline 1 so Send；Conveying pipeline 1 is the pipeline for being passed through and conveying powder granule 3, and inner tube 2 wants much tiny compared to conveying pipeline 1, conveying Pipe 1 and inner tube 2 be substantially in the horizontal direction, i.e., conveying pipeline 1 and inner tube 2 both can be it is horizontally extending or It is slightly at an angle with horizontal direction, as long as can realize that the powder granule 3 in conveying pipeline 1 conveys.

Conveying pipeline 1 and the top of inner tube 2 connect with the first air-supply arrangement, i.e. same one end of conveying pipeline 1 and inner tube 2 connects The first air-supply arrangement is passed through, first air-supply arrangement is used to be passed through air-flow into conveying pipeline 1 and inner tube 2, and the first air-supply dress Put both can be to include two blowing units that respectively conveying pipeline 1 and inner tube 2 are blown or a blowing unit simultaneously Blown for conveying pipeline 1 and inner tube 2.So, after the first air-supply arrangement is passed through air-flow into conveying pipeline 1, the powder in conveying pipeline 1 Particle 3 is just caudad conveyed in the presence of air-flow by the head end of conveying pipeline 1.

Often pile up, and pile up in the somewhere of pipeline during being conveyed due to powder granule 3 in conveying pipeline 1 Generation can assemble more powder granules 3 again, eventually result in pipeline obstruction, this is also exactly the length difficult to realize of powder granule 3 The reason for distance conveying.Therefore, the utility model embodiment is provided with multiple fumaroles 21, multiple jets in the bottom of inner tube 2 Length direction arrangement of the hole 21 along inner tube 2, i.e., multiple fumaroles 21 are distributed in the bottom axially spaced-apart of inner tube 2, so, inner tube 2 In compressed air through fumarole 21 enter conveying pipeline 1 in, material can be cut or be disturbed, thus suppress obstruction hair It is raw；And when feed blocking occurs for somewhere in conveying pipeline 1, the discharge pressure for blocking front increases and forces delivery air by this Fumarole 21 enter inner tube 2, into inner tube 2 compressed air stream more from first of clog downstream opening with higher speed Degree outflow, brushed so as to be formed to the rear that material is blocked at this, disturbance is produced to obstruction material, it is real so as to which obstruction be disintegrated The dredging now blocked.

In conjunction with shown in Fig. 3, blocker ring 22 is equipped with inner tube 2 and at each fumarole 21, due to blocker ring 22 internal diameter is less than the internal diameter of inner tube 2, and blocker ring 22 itself also has certain thickness, so the air-flow in inner tube 2 is flowing High pressure can be formed when moving to blocker ring 22, is more also more rapidly sprayed by fumarole 21, and blocker ring 22 will can also spray Stomata 21 spray rear water conservancy diversion from air-flow to obstruction, so as to more effectively eliminate obstruction；Further, blocker ring 22 can be with The middle position of fumarole 21 is arranged on, two parts fumarole 21 respectively accounts for half before and after such blocker ring 22, can make air-flow Inflow and spray relative equilibrium.

Wherein, in terms of the radial direction of inner tube 2, it is in substantially inverted v-shaped structure that the inwall of fumarole 21, which is, i.e. if edge The axis vertical of inner tube 2 cuts inner tube 2, then the both sides side wall of fumarole 21 is distributed in two sides of an inverted V-arrangement Bian Shang, the fumarole 21 of V-arrangement are more beneficial for air-flow and flow into and spray inner tube 2.

The lower section of conveying pipeline 1 is provided with multiple air injection units 4, and length direction of multiple air injection units 4 along conveying pipeline 1 is arranged, Air injection unit 4 is used to spray into gas into conveying pipeline 1, thus blows afloat the powder granule 3 of the bottom of conveying pipeline 1 to suspended state, So as to be more beneficial for effective conveying of powder granule 3.

Specifically, air injection unit 4 includes the inlet chamber 41 connected with the bottom of conveying pipeline 1, the bottom of inlet chamber 41 is provided with The air intake duct connected with the second air-supply arrangement, air intake duct is interior to be provided with umbrella shape elastic component 42, can be specifically made up of elastomeric material, umbrella Shape elastic component 42 is fixed centrally through support relative to air intake duct；In its natural state, umbrella shape elastic component 42 is umbrella shape, umbrella The edge of shape elastic component 42 contacts with the inner wall sealing of air intake duct, when the second air-supply arrangement is blown into air intake duct, umbrella shape bullet Property part 42 edge to the curving of inlet chamber 41, i.e., umbrella shape elastic component 42 it is excessive be flared to it is horn-like so that umbrella shape elastic component Gap is formed between 42 edge and the inwall of air intake duct, air-flow is passed into inlet chamber 41, is passed into inlet chamber 41 In air-flow powder granule 3 is blown afloat to suspended state again, so as to be more beneficial for the long distance delivery of powder granule 3.

Wherein, umbrella shape elastic component 42 in its natural state can be by the liquid guide flow that may be mingled with material extremely for umbrella shape The edge of umbrella shape elastic component 42, liquid are defeated so as to realize again by permeating between the edge and air intake duct of umbrella shape elastic component 42 The discharge of liquid in expects pipe 1.

In addition, air intake duct is preferably to be tilted from outside to inside to the tail end direction of conveying pipeline 1, the air-flow being so blown into also can be right Certain booster action is played in the conveying of material；Inlet chamber 41 is preferably gradually increase from the bottom to top, is so more conducive to thing Material is blown to suspended state.

To sum up, a kind of Pneumatic conveying pipeline provided by the utility model, by setting inner tube 2 in conveying pipeline 1, and inside The bottom of pipe 2 sets multiple fumaroles 21 along its length, so as to which when blocking in conveying pipeline 1, obstruction front is formed High pressure draught flows into inner tube 2 first, and the high pressure draught for flowing into inner tube 2 is sprayed by the fumarole 21 for blocking rear again, thus from resistance The rear of plug is formed to it to be disintegrated, and realizes the purpose of dredging obstruction；Meanwhile coordinate and multiple jets are set in the lower section of conveying pipeline 1 Unit 4, the powder granule 3 of the bottom of conveying pipeline 1 is blown afloat to suspended state, so as to be more beneficial for the effective defeated of powder granule 3 Send, even if thus conveying the larger powder granule 3 of particle diameter, long distance delivery can also be realized.

Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model technical principle is not departed from, some improvement and replacement can also be made, these change Enter and replace and also should be regarded as the scope of protection of the utility model.
