Abstract
The utility model discloses an automatic cleaning device for a coal powder injection main pipe, which comprises a coal powder injection valve, a first pressure measuring device and a second pressure measuring device which are all arranged on a coal powder injection main pipe, wherein a coal powder returning pipeline leading to a coal powder bin is arranged between the coal powder injection valve and the first pressure measuring device on the coal powder injection main pipe; a coal powder returning valve is arranged on the coal powder returning pipeline; a plurality of air blowing cleaning pipelines are arranged between the first pressure measuring device and the second pressure measuring device; and the air blowing cleaning pipelines comprises cleaning valves communicated with the coal powder injection main pipe and a back air blowing pipeline. As a pneumatic ball valve is used, program automatic control is realized, labor intensity of workers is reduced, and cleaning period is greatly shortened. The coal powder cleaned is returned to the coal powder bin, thereby reducing environmental pollution and improving using efficiency of the coal powder.
Description
Technical field
The utility model relates to the automatic cleaning device that coal powder injection is responsible in Steel Plant's coal injection system.
Background technology
At present, the cleanings manually of adopting are responsible in the coal powder injection in the general Steel Plant coal injection system more.As shown in Figure 1, existing coal powder injection person in charge clearing apparatus comprises cleaning valve 6, snifting valve 7 and exhaust-valve 9 and the associated pipe that is installed on the coal powder injection person in charge 1.When judging the coal powder injection person in charge 1 generation obstruction by the pressure reduction of 2 of pressure tap a, b, open exhaust-valve 9, cleaning valve 6 and snifting valve 7 between A1 to the A2 section successively, A1-A2 section pipeline is purged, gas circuit flows to and is B2 → C2 → A2 → A1 → C1 → D1, and the coal dust that cleans out directly is discharged in the atmosphere; By same operation, successively to A2-A3 section, A3-A4 section ... the An-1-An section ... clean successively, be responsible for 1 unimpeded until coal powder injection.
Valve in the existing clearing apparatus is manual ball valve, needs operation manually, and whether the artificial judgment pipeline is unobstructed, and labor strength is big; Cycle to the cleaning of whole piece coal powder injection main line is long, and production has caused influence to a certain extent to blast furnace; Coal dust after the cleaning or foreign material etc. all are discharged in the atmosphere, and environment has also been caused pollution.
Summary of the invention
Goal of the invention: the utility model provides a kind of person in charge's of coal powder injection efficiently automatic cleaning device at the shortcoming of existing manual clearing apparatus inefficiency.
Technical scheme: in order to solve the problems of the technologies described above, the utility model has adopted following technical scheme:
The automatic cleaning device that a kind of coal powder injection is responsible for, it comprises coal powder injection valve, a pressure tester and No. two pressure tester that are arranged on the coal powder injection person in charge, on the coal powder injection between coal powder injection valve and the pressure tester is responsible for, be provided with the powder retrieving pipe road of leading to Pulverized Coal Bin, install back the powder valve on it; Be provided with some the cleaning pipelines of blowing between a pressure tester and No. two pressure tester, described air blowing cleaning pipeline comprises the cleaning valve that is communicated with the coal powder injection person in charge and blowback air pipeline.
Wherein, described coal powder injection valve, time powder valve and cleaning valve are the pneumatic ball valve of PLC control, and described pneumatic ball valve all is electrically connected with Central Control Room PLC system.
The beneficial effects of the utility model are as follows: adopt the pneumatic ball valve cleaning, can realize procedure auto-control, improved labor strength, shortened cleaning period greatly; The coal dust of cleaning returns Pulverized Coal Bin, has reduced environmental pollution, has improved the coal dust utilising efficiency simultaneously.
Description of drawings
Fig. 1 is responsible for clearing apparatus for coal powder injection in the existing coal injection system.
Fig. 2 is a structural representation of the present utility model.
Embodiment:
With reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in further detail.But the utility model is not limited to given example.
As shown in Figure 2, the automatic cleaning device that a kind of coal powder injection of the present utility model is responsible for, it comprises that being arranged on coal powder injection is responsible for the coal powder injection valve 2 on 1, a pressure tester 3 and No. two pressure tester 4, be responsible on 1 to be provided with the powder retrieving pipe road of leading to Pulverized Coal Bin in the coal powder injection between coal powder injection valve 2 and the pressure tester 3, install back powder valve 5 on it; Be provided with some air blowing cleaning pipelines between a pressure tester 3 and No. two pressure tester 4, described air blowing cleaning pipeline comprises the cleaning valve 6 that is communicated with the coal powder injection person in charge 1 and blowback air pipeline 7.Described coal powder injection valve 2, time powder valve 5 and cleaning valve 6 are the pneumatic ball valve of PLC control, and described pneumatic ball valve all is electrically connected with Central Control Room PLC system.
When judging coal powder injection person in charge generation obstruction by 2 pressure reduction of pressure tap a, b, time powder valve 5,6 pairs of A-A1 sections of the cleaning valve pipeline opened successively on the A1 section pipeline by coal powder injection Central Control Room PLC system purge, can judge whether pipeline is unimpeded by the pressure of pressure tap a simultaneously, gas circuit flows to and is B1 → D1 → C1 → A1 → A, and the coal dust that cleans out turns back to the Pulverized Coal Bin in coal powder injection workshop by time powder valve 5.By same operation, successively to A-A2 section, A-A3 section ... the A-An section ... clean successively, unimpeded until the coal powder injection main line.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
