Abstract
The utility model discloses a powder conveying pipeline, and particularly relates to a wear-resistant powder conveying pipeline without dust accumulation. In the pipeline, an anticorrosion and wear-resistant layer is arranged on the inner wall of a steel pipe wall, and the thickness of the anticorrosion and wear-resistant layer ranges from 1.5mm to 3mm; and at least a row of dust blowing holes are formed on the lower half pipe wall. The pipeline has good wear-resistant and corrosion-resistant performances; and dust accumulated in the pipeline can be effectively removed, so as to reduce the production cost.
Description
Technical field
The present invention relates to a kind of powder conveying pipeline, particularly relate to a kind of no dust stratification anticorrosion antiwear powder conveying pipeline.
Background technique
At present, industrial and mineral microparticle product extensively adopts strength to pass through line transportation, all is to adopt simple cylindrical conduit structural type because Pneumatic conveying pipeline one of the prior art is removed, and causes gambling pipe phenomenon when therefore carrying at the bottom of the easy deposited tube of material.Because fed distance is generally longer,, the plugging phenomenon is difficult to dredge maintenance in case taking place.In addition, because of the difference of powder material characteristic, can produce in various degree wearing and tearing to tube wall in course of conveying, particularly higher when powder hardness, under the bigger situation of flow velocity, tube wall can be subjected to wearing and tearing largely.In addition, some powder also can produce corrosion to pipeline.
Chinese patent 99231938.2 discloses a kind of powdery or granular material fluidization Pneumatic conveying pipeline, crooked guide plate is installed on the upper tube wall in conveyance conduit, when carrying beginning, pressurized air enters conveyance conduit along throughput direction, when pressurized air is flowed through guide plate, because the special construction of guide plate, air-flow will be jetted downwards along the angle that guide plate forms, the winding-up air-flow is subjected to being transformed into the air-flow that makes progress along throughput direction after the reflection of material and bottom tube wall in the conveyance conduit, material can be formed fluidization like this and move forward, in pipeline fluidization course of conveying, because the flow velocity of the velocity ratio fluidized material of conveyance conduit compressed air is fast, the fluidized material of Liu Donging constantly obtains the air-flow makeup energy that guide plate produces forward, thereby guarantee that material is in flowing state in whole conveyance conduit, and in conveyance conduit, forming stable fluidization course of conveying, conveying material is being difficult for deposition in course of conveying.Yet this method has increased the weight of pipeline, and guide plate is installed cumbersome, can increase cost, and in addition, this method does not strengthen the wear resistance and the corrosion resistance of pipeline yet.
Summary of the invention
The technical problem to be solved in the present invention is: overcome the defective that exists in the prior art, strengthen wear resistance, the corrosion resistance of powder conveying pipeline, and make conveyance conduit be in no dust stratification state fully.
For solving the problems of the technologies described above, technological scheme of the present invention is: scribbling thickness on the inwall of conveyance conduit is the anticorrosion antiwear layer of 1.5 ~ 3mm, have at least a row to blow grey hole on second tube wall, the aperture of blowing grey hole is 3 ~ 6mm, and arbitrary row last two adjacent pitch-rows of blowing between the grey hole are 0.7 ~ 1.3m.
No dust stratification anticorrosion antiwear powder conveying pipeline according to above-mentioned blows grey hole perpendicular to tube wall.
According to above-mentioned no dust stratification anticorrosion antiwear powder conveying pipeline, grey hole exits place installation Jiao Gai can blown.
According to above-mentioned no dust stratification anticorrosion antiwear powder conveying pipeline, Jiao Gai is made up of end cap and bottom, and there is an aperture at the center of bottom, and the diameter of aperture is greater than the diameter that blows grey hole, and bottom is fixed on and blows place, grey hole in the pipeline.
According to above-mentioned no dust stratification anticorrosion antiwear powder conveying pipeline, conveyance conduit can be circular, can be square, can also be oval.
The invention has the beneficial effects as follows:
1) owing to scribbles the anticorrosion antiwear layer that thickness is 1.5 ~ 3mm, can make postpone 3.8 times the wear-resistant working life of pipeline, antiseptic property strengthens 3 ~ 5 times, therefore have wear resistance and antisepsis preferably, can be widely used in industrial and mineral microparticle powder products such as cement, aluminium oxide, chemical industry and carry and environmental protection dust-removing waste gas air inducing pipeline in strength; Can adopt sheet-metal duct in actual the use, can effectively reduce production costs.
2) under the effect of blowing grey hole, the tiling pipeline is in no dust stratification state in the course of the work fully, has ensured the smooth and easy naturally of pipeline, has improved transportation work efficient, and letter has economized a large amount of parking maintenance time and expense.
3) this pipeline can be in rustless smooth state in high humidity, high acid or alkali environment midium or long term.

Embodiment
Embodiment 1: referring to Fig. 1, Fig. 2, Fig. 3, among the figure, 1 is conveyance conduit, and 2 is the anticorrosion antiwear layer, and 3 for blowing grey hole.The diameter of conveyance conduit 1 is 0.5m, and scribbling thickness on the inwall of conveyance conduit 1 is the anticorrosion antiwear layer 2 of 2mm, strengthens the wear resistance and the corrosion resistance of steel pipe walls.Have two rows to blow grey hole 3 on second tube wall of conveyance conduit, the diameter that blows grey hole 3 is 4mm, and two rows blow grey hole and are staggered on second tube wall.Arbitrary row last two adjacent distances of blowing between the grey hole 3 are 1m.Do the time spent as air inducing, be in negative pressure state in the pipeline, at this moment the outer normal pressure air-flow of pipe is broken through and is blown grey hole 3 and be introduced in the pipe, and drive the pipeline lower inner wall and fall the material secondary and kicks up, thus removing pipeline dust stratification.
Embodiment 2: substantially the same manner as Example 1, and referring to Fig. 4, Fig. 5, Fig. 6.Among the figure, 4 is Jiao Gai, and 5 is end cap, and 6 is bottom, and 7 is aperture.Difference is: the diameter of conveyance conduit is 1m, is blowing grey hole 3 place's fixing glue lids 4, and glue lid 4 is made up of end cap 5 and bottom 6, and there is an aperture 7 at the center of bottom 6, and the slightly larger in diameter of aperture 7 is in the diameter that blows grey hole 3.Bottom 6 is fixed on and blows 3 places, grey hole in the pipeline, blows grey hole 3 and can appear from aperture 7 fully.Do the time spent as air inducing, be in negative pressure state in the pipeline, at this moment the outer normal pressure air-flow of pipe is broken through and is blown grey hole 3 and aperture 7 and wash the end cap 5 of glue lid 4 open and be introduced in the pipe, and drive the pipeline lower inner wall and fall the material secondary and kicks up, thus removing pipeline dust stratification.When air inducing stopped, the end cap 5 of glue lid 4 was closed under the effect that carries elastic force automatically.
