Abstract
The utility model discloses a high pressure nitrogen charging device for delivering powdered coal. The high pressure nitrogen charging device for delivering the powdered coal comprises a powdered coal bucket, a high pressure nitrogen distributing chamber, a flange and a high pressure nitrogen inlet pipe. High pressure nitrogen enters the high pressure distributing chamber from the high pressure nitrogen inlet pipe, and enters the powdered coal bucket from smooth round holes to blow the powdered coal to be safely delivered, wherein the round holes are evenly distributed around the powdered coal bucket. Materials are made of stainless steel plates, and therefore the materials can not be damaged easily. The high pressure nitrogen is inflated from the smooth round holes densely distributed on the periphery of the powdered coal, the round holes can not be blocked easily, and nitrogen distribution is even. The high pressure nitrogen charging device for delivering the powdered coal has the advantages of being simple in structure, even in nitrogen distribution and durable.
Description
Technical field
The utility model relates to fine coal conveying high-pressure nitrogen charging device, is directly involved in the fine coal conveying high-pressure and fills the nitrogen device.
Background technology
Some Domestic nitrogen fertilizer plant has built the pressurization gasifying powder coal device at present; that feed coal is processed into microfine coal through comminutor, ball grinding mill; easily burning; all adopt high pressure nitrogen protection to carry in transportation, the metal sintering material of original adoption is made fills the nitrogen device, often stops up; break; and gas distribution is inhomogeneous, and it is even to seek a kind of difficult obstruction gas distribution, and long-lived nitrogen charging device is necessary.
Summary of the invention
The purpose of this utility model is made a kind of difficult obstruction exactly, and gas distribution is even, and long-lived gas filled device, fills frequent obstruction of nitrogen device before overcoming and breaks the problem that gas distribution is inhomogeneous.
The purpose of this utility model is achieved in that the fine coal conveying high-pressure fills the nitrogen device, have fine coal bucket, high pressure nitrogen distributing chamber, upper flange, high pressure nitrogen inlet pipe, lower flange, the fine coal bucket is the cone that the corrosion-resistant steel coiled sheet with uniform circular hole is welded into, upper end welding upper flange, welding lower flange in lower end in the peripheral solder nitrogen distributing chamber of fine coal bucket, welds the high pressure nitrogen induction pipe in nitrogen distributing chamber near bottom opening, upper flange is connected with the fine coal bucket, and lower flange is connected with convey coal pipe.
The utility model is owing to adopt the full smooth circular hole of even brill on stainless steel sheet, then volume is welded into a cone, at cone upper end welding upper flange, be connected with the fine coal bucket, at the lower end of cone welding lower flange, be connected with convey coal pipe, fill the nitrogen chamber in the cone periphery with high pressure of stainless steel sheet welding, near the structure of filling bottom, nitrogen chamber perforate welding high pressure nitrogen inlet pipe, high pressure nitrogen enters high pressure nitrogen distributing chamber from the high pressure nitrogen inlet pipe, smooth circular hole by on the lower cone enters the fine coal bucket uniformly, blows the fine coal operation, because material has adopted the stainless steel sheet making, cracky not, high pressure nitrogen is filled with from the peripheral smooth circular hole that gathers of fine coal bucket, be difficult for stopping up and gas distribution even.
Description of drawings
Accompanying drawing shows structural representation of the present utility model, and the utility model is described in further detail below in conjunction with accompanying drawing.
The specific embodiment
Accompanying drawing shows a kind of fine coal conveying high-pressure of the utility model and fills the nitrogen device, has fine coal bucket 1, high pressure nitrogen distributing chamber 2, upper flange 3, high pressure nitrogen inlet pipe 4, lower flange 5.
Described fine coal bucket 1 is evenly boring on the thick stainless steel sheet of 12mm, aperture Φ 10mm, and pitch-row 200mm, then the corrosion-resistant steel coiled sheet with boring is welded into a cone.Flange 3 at the upper end of fine coal bucket 1 welding DN1000.PN2, flange 5 at cone lower end welding DN400.PN2, stainless steel sheet in the periphery of fine coal bucket 1 with thickness 12mm is welded into high pressure nitrogen distributing chamber 2, at the bottom perforate welding high pressure nitrogen inlet pipe 4(Φ 159*3.5 near high pressure nitrogen distributing chamber 2, length 250mm).
Principle of work:
Be connected with fine coal bucket 1 with upper flange 3, lower flange 5 is connected with the fine coal delivery pipe, and high pressure nitrogen inlet pipe 4 is connected with nitrogen header pipe.High pressure nitrogen enters high pressure nitrogen distributing chamber 2 from high pressure nitrogen inlet pipe 4, sees through the smooth circular hole that gathers around the fine coal bucket 1 and enters fine coal bucket 1 inside, blows fine coal and carries.
Characteristics of the present utility model are simple in structure, and gas distribution is even, and are durable in use, without stopping up.
