Description
Technical Field
The utility model belongs to the technical field of machinery, a draw-off pipe of connecting flue is related to.
Background
The connecting flue in the boiler is used for safely conveying high-temperature flue gas.
In order to transport the flue gas in a divided manner, a three-way or four-way pipe section is generally adopted. The existing tee joint or four-way pipe section is too complex in structure, so that the manufacturing cost is higher.
In addition, the tee joint or the four-way pipe section with the integrated structure has low structural strength due to technological factors, and is easy to damage under the action of external force.
SUMMERY OF THE UTILITY MODEL
The utility model aims at the above-mentioned problem that prior art exists, provide a high and compact structure's of stability connection flue's stand-off pipe.
The purpose of the utility model can be realized by the following technical proposal:
the utility model provides a connection flue's fairlead, includes that inside is cavity and both ends open-ended body, its characterized in that, still including being cylindric honeycomb duct, above-mentioned honeycomb duct links firmly on the body and the honeycomb duct lower extreme is located this internally, and the body is stretched out to the honeycomb duct upper end, the honeycomb duct lower extreme is the inclined plane, and above-mentioned inclined plane forms the water conservancy diversion portion of a slope at the honeycomb duct lower extreme, and the honeycomb duct upper end has the ring flange that is used for being connected with the pipeline section.
In the above-mentioned eduction tube connected with the flue, the draft tube is connected with the center of the body.
In the eduction tube connected with the flue, the draft tube is vertical to the body.
In the eduction tube connected with the flue, the inclination angle of the lower end of the draft tube is 40-60 degrees.
The drainage tube is creatively connected with the drainage tube on the body, although the drainage tube is vertically arranged with the body. However, part of the flue gas in the main body can be stably guided into the guide pipe through the guide part at the lower end of the guide pipe.
That is to say, a part of flue gas is directly exported through the body, and another part of flue gas is exported through the honeycomb duct.
Because the honeycomb duct is stably connected to the body, the whole eduction tube has a compact structure and high practical value.
In the above-mentioned eduction tube connected with the flue, the draft tube is fixedly connected on the body by welding.
In the above-mentioned outlet pipe connected with the flue, the upper part of the body is planar.
The structure can enable the upper part of the eduction tube to be flat, and the structure compactness of the eduction tube is improved.
In the above-mentioned eduction tube connected with the flue, the lower part of the body is provided with a concave collecting part.
The dust in the flue gas can be smoothly accumulated at the collecting part.
In the above-mentioned eduction tube connected with the flue, the lower part of the body is also fixedly connected with a tubular drainage tube, and the drainage tube is provided with a valve which can be opened and closed.
The dust accumulated at the collecting part can be stably discharged after the valve is opened.
Compared with the prior art, the eduction tube of the connection flue has the advantages that the draft tube is directly and fixedly connected to the body, the size of the draft tube is small, the strength of the whole eduction tube is not affected, the stability is high, and the structure is compact.
Certainly, under the effect of water conservancy diversion portion can be effectual make the flue gas because two branches of body and honeycomb duct reposition of redundant personnel, further improvement its stability, have very high practical value.
Drawings
FIG. 1 is a schematic structural diagram of an outlet pipe of the flue.
In the figure, 1, a body; 1a, a collecting part; 2. a flow guide pipe; 2a, a flow guide part; 3. a drain pipe; 4. and (4) a valve.
Detailed Description
As shown in fig. 1, the outlet pipe of the flue includes a body 1 with a cavity and two open ends, and further includes a cylindrical flow guide pipe 2, the flow guide pipe 2 is fixedly connected to the body 1, the lower end of the flow guide pipe 2 is located in the body 1, the upper end of the flow guide pipe 2 extends out of the body 1, the lower end of the flow guide pipe 2 is an inclined plane, the inclined plane forms a flow guide part 2a inclined at the lower end of the flow guide pipe 2, and the upper end of the flow guide pipe 2 is provided with a flange plate connected with a pipe section.
The honeycomb duct 2 is connected to the center of the body 1.
The honeycomb duct 2 is perpendicular to the body 1.
The lower end of the draft tube 2 is inclined at an angle of 40-60 degrees.
The honeycomb duct 2 is fixedly connected to the body 1 through welding.
The upper part of the body 1 is planar.
The lower part of the body 1 is provided with a concave collecting part 1 a.
The lower part of the body 1 is also fixedly connected with a tubular drainage pipe 3, and the drainage pipe 3 is provided with a valve 4 which can be opened and closed.
The drainage tube is creatively connected with the drainage tube on the body, although the drainage tube is vertically arranged with the body. However, part of the flue gas in the main body can be stably guided into the guide pipe through the guide part at the lower end of the guide pipe.
That is to say, a part of flue gas is directly exported through the body, and another part of flue gas is exported through the honeycomb duct.
Because the honeycomb duct is stably connected to the body, the whole eduction tube has a compact structure and high practical value.
