Abstract
A gland sealing device for a branch pipe flue of a roasting furnace comprises a gland (1), a rock wool plate (2), a smoke pipe (3) and a valve (4), wherein the smoke pipe (3) with certain height is welded above the branch pipe flue (6); the valve which can be opened or closed is arranged on the smoke pipe in a position close to the middle part; the convex circular truncated cone-shaped gland is arranged at a smoke outlet at the upper part of the smoke pipe; the rock wool plate is laid on the periphery of the contact part of the gland and the smoke pipe; and a concrete platform (5) used for operation is arranged beside the smoke outlet at the upper part of the smoke pipe. When the gland sealing device is mounted, the distance between the upper plane of the concrete platform and the end plane of the outlet of the smoke pipe is larger than or equal to 5mm so as to tilt the heavy gland. 45 degree's chamfering is made on the external diameter of the smoke outlet at the upper part of the smoke pipe through a polishing machine or mechanical processing, and then the gland can cling to the smoke outlet at the upper part of the smoke pipe. Through the double-sealing effect of the valve and the rock wool plate, the sealing effect of the gland sealing device is ensured, and meanwhile, the effects of heat insulation and sound insulation are achieved, the loss of negative pressure is prevented.
Description
Technical field
The utility model belongs to the roaster technical field, especially a kind of gland seal device of roaster arm flue.
Background technology
Roaster is that metallurgy, charcoal are plain, the main production equipments of chemical industry.Material in the roaster needs certain negative pressure in airtight furnace chamber internal combustion, can produce a large amount of flue gas and dust in the negative pressure extracting process, and these flue dust need enter purification dust removal system through the annular flue of roaster, enter atmosphere by chimney.
For ease of collecting the flue gas in the furnace chamber, furnace chamber is other to be provided with vertical arm flue and annular flue UNICOM.Be provided with can be for operation, current concrete or steel platform on the plane on the arm flue, plays sealing function at the upper edge port of usual situation lower branch line flue by circular cover.
But the existing poorly sealed in actual use reality of gland that is used for the arm flue causes the negative pressure in the system pipeline to run off, and has influenced ordinary production, simultaneously surrounding air has been caused adverse effect.
Summary of the invention
For addressing the above problem, the utility model has designed a kind of gland seal device of roaster arm flue, and this gland seal device can improve the flue sealing effectiveness, prevents the loss of negative pressure.
For realizing above-mentioned utility model purpose, the utility model adopts following technical scheme:
The gland seal device of described roaster arm flue is made of gland, rock cotton board, smoke pipe and valve, smoke pipe has certain height and is welded on arm flue top, be provided with the valve of opening or closing at the nearly middle part of smoke pipe, the outlet flue on smoke pipe top is provided with protruding round table-like gland, one week of contact position of gland and smoke pipe is equipped with rock cotton board, and at the other concrete platform that is used to operate that also is provided with of the outlet flue on smoke pipe top.
The gland seal device of described roaster arm flue, its smoke pipe are rolled by steel plate and form, and the outlet flue external diameter on smoke pipe top has 45 ° of chamferings.
The gland seal device of described roaster arm flue, great circle external diameter＞smoke pipe the external diameter of its protruding round table-like gland, the unsettled dome platform external diameter＜smoke pipe internal diameter in smoke pipe of gland has the rock cotton board of thermal insulation or sound insulation in the close dome platform one week laying of the large round end surface of gland.
The gland seal device of described roaster arm flue, its rock cotton board is circular and circular width and can covers on the wall thickness of smoke pipe, the laying depth of ring-type rock cotton board is 5～10mm, the internal diameter of ring-type rock cotton board 〉=gland dome platform external diameter, the external diameter of ring-type rock cotton board＞smoke pipe external diameter.
The gland seal device of described roaster arm flue, the last plane of its concrete platform is to the distance 〉=5mm on smoke pipe port of export plane.
Owing to adopt aforesaid technical scheme, the utlity model has following superiority:
1, the utility model is simple in structure, and is easy to make, flexible for installation, and effect is remarkable.
2, valve of the present utility model and rock cotton board have the dual-seal effect, have guaranteed the sealing effectiveness of gland seal device, have also reached the effect of adiabatic sound insulation simultaneously, have prevented the loss of negative pressure.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the local enlarged diagram in I place of Fig. 1;
Among the above-mentioned figure: the 1-gland; The 2-rock cotton board; The 3-smoke pipe; The 4-valve; The 5-concrete platform; The 6-flue.
The specific embodiment
Specify gland seal device of the present utility model in conjunction with Fig. 1,2.
At first, the gland seal device of roaster arm flue of the present utility model is made of gland 1, rock cotton board 2, smoke pipe 3 and valve 4, smoke pipe 3 has certain height and is welded on arm flue 6 tops, be provided with the valve 4 of opening or closing at the nearly middle part of smoke pipe 3, the outlet flue on smoke pipe 3 tops is provided with protruding round table-like gland 1, gland 1 is equipped with rock cotton board 2 with smoke pipe 3 in one week of contact position, and at the other concrete platform 5 that is used to operate that also is provided with of the outlet flue on smoke pipe 3 tops.
Described smoke pipe 3 is rolled by steel plate and forms, and the outlet flue external diameter on smoke pipe top has 45 ° of chamferings.At the nearly middle part of smoke pipe 3 mounted valve 4.It is decide according to the upset diameter of valve 4 and the smoke outlet flue spacing of reserving the smoke pipe two ends that smoke pipe 3 has certain height, and different valves 4 has different upset diameters, the upset diameter of valve 4 will be with smoke pipe 3 interior through coupling with the assurance sealing effectiveness.Smoke pipe 3 materials are selected Q235 usually for use.
Great circle external diameter＞smoke pipe the external diameter of described protruding round table-like gland 1, gland 1 unsettled dome platform external diameter＜smoke pipe internal diameter in smoke pipe 3 has the rock cotton board of thermal insulation or sound insulation in the close dome platform one week laying of the large round end surface of gland 1.In concrete the use, the material that gland 1 is selected for use is identical with smoke pipe 3.
Described rock cotton board 2 is circular and circular width and can covers on the wall thickness of smoke pipe 3, and the laying depth of ring-type rock cotton board is 5～10mm, the internal diameter of ring-type rock cotton board 〉=gland dome platform external diameter, the external diameter of ring-type rock cotton board＞smoke pipe external diameter.
