Description
Technical Field
The utility model relates to a metallurgical industry pneumatic conveying system especially relates to a storehouse pump export mixed flow device.
Background
In order to increase the ash-air ratio and reduce the consumption of compressed air, a dense-phase type bin pump is generally used in which air is flushed into the bin pump first, and a delivery valve is opened when the air pressure in the bin pump rises to a certain pressure. Due to the restriction of high material specific gravity, large particle size and relatively large friction force with the pipe wall in metallurgy, the existing conveying method usually causes pipeline blockage at a position short of the outlet of the bin pump, and system paralysis is caused.
SUMMERY OF THE UTILITY MODEL
The applicant aims at the defects and carries out research and improvement to provide a mixed flow device at the outlet of a bin pump.
The utility model provides a storehouse pump export mixed flow device, is including the mixed flow pipe of connecting storehouse pump export and defeated grey pipeline, mixed flow outside of tubes coupling sleeve pipe, set up a plurality of intercommunication mixed flow pipes and sheathed tube mixed flow hole on the position that mixed flow pipe is located the cover intraductal, connect a plurality of air inlet joint on the cover pipe, air inlet joint connects the branch pipe of admitting air, the branch union coupling that admits air is responsible for admitting air, the main pipe of admitting air is connected the compressed air source, and admits air and is responsible for and go up the connection pneumatic control valve.
As a further improvement of the above technical solution:
and the air inlet branch pipes are connected with check valves.
And the two sides of the mixed flow pipe are both connected with connecting flanges which are convenient for the disassembly and the assembly of the mixed flow pipe.
The lower end of the sleeve is also connected with a sleeve cleaning pipe, and the open end of the sleeve cleaning pipe is connected with the sealing flange plate through a connecting flange.
The utility model has the advantages as follows: the bin pump outlet flow mixing device is connected between the bin pump outlet and the ash conveying pipe, compressed air enters the flow mixing pipe through the sleeve and the flow mixing hole, the material plug can be broken, the material concentration is reduced, and pipeline blockage is avoided.
Drawings
Fig. 1 is a schematic structural view of the bin pump outlet flow mixing device provided by the present invention.
In the figure: 1. a mixed flow tube; 11. a mixing hole; 2. a sleeve; 21. an air inlet joint; 22. cleaning the pipe by the sleeve; 23. sealing the flange plate; 3. an intake branch pipe; 31. a check valve; 4. a main air inlet pipe; 41. a pneumatic control valve; 5. and connecting the flanges.
Detailed Description
The following describes a specific embodiment of the present embodiment with reference to the drawings.
As shown in fig. 1, the mixer device for the outlet of the silo pump in this embodiment includes a mixing tube 1 connecting the outlet of the silo pump and the ash conveying pipeline, two sides of the mixing tube 1 are both connected to a connecting flange 5 facilitating the disassembly and assembly of the mixing tube 1, the mixing tube 1 is externally connected to a casing 2, the mixing tube 1 is located in the casing 2 and is provided with a plurality of mixing holes 11 communicating the mixing tube 1 and the casing 2, the casing 2 is connected to a plurality of air inlet joints 21, the air inlet joints 21 are connected to an air inlet branch tube 3, the air inlet branch tube 3 is connected to an air inlet main tube 4, the air inlet main tube 4 is connected to a compressed air source, the air inlet main tube 4 is connected to a pneumatic control valve 41, the air inlet branch tube 3 is connected to a check valve 31, the check valve 31 plays a role in preventing backflow of materials.
The sleeve pipe 2 lower extreme still is connecting sleeve pipe clearance pipe 22, and sleeve pipe clearance pipe 22 open end passes through flange 5 and connects sealing flange dish 23, has some materials to get into the condition of sleeve pipe 2 when storehouse pump export mixed flow device uses, so need regularly open sealing flange dish 23, manage sleeve pipe clearance pipe 22 and connect in updraft ventilator, take out the material in the sleeve pipe 2, prevent that the material from blockking up and causing storehouse pump export mixed flow device to become invalid in sleeve pipe 2.
When the bin pump outlet mixed flow device of the embodiment is used, the mixed flow pipe 1 is connected between the bin pump outlet and the ash conveying pipe through the connecting flange 5, materials in the bin pump can pass through the mixed flow pipe 1 to enter the ash conveying pipe for feeding, in the feeding process, the pneumatic control valve 41 is opened, compressed air is conveyed into the sleeve pipe 2 through the air inlet main pipe 4 and the air inlet branch pipe 3 by starting the compressed air source, then the compressed air passes through the mixed flow hole 11 again, the compressed air uniformly enters the mixed flow pipe 1, the compressed air is mixed with the materials, the material concentration can be reduced, and pipeline blockage is avoided.
The above description is for the purpose of explanation and not limitation of the invention, which is defined in the claims, and any modifications may be made without departing from the basic structure of the invention.
