Description

A kind of combustion fan that can clean screen pack automatically
Technical field
The present invention relates to a kind of combustion fan that can clean screen pack automatically, belong to Fan Equipment technical field.
Background technology
Terminal blower fan refers to that air intake duct is directly in contact with air, and air intake duct front end is equipped with screen pack, and air is in blower fan The lower screen pack by air intake duct front end of driving enters a kind of blower fan that pipeline participates in the technology controlling and process such as burning, drying.Metallurgy enterprise Combustion fan used in industry rolling mill production line belongs to terminal blower fan.The combustion fan of rolling mill production line is located at continuous annealing stove heat Section, bringing-up section can be divided into 7 Ge Huo14Ge areas according to producing line structure, and each area is equipped with a combustion fan, main function Be to provide power to draw air into, mixed with coal gas at burner, by fire rod igniting make its burn gives strip heat, with up to To the purpose of strip annealing.In order to ensure to inject the cleaning of air, screen pack is installed at the air inlet duct of combustion fan;It is actual In production process, each area of bringing-up section often causes sequential stop jumping because combustion air flow fluctuation is big, causes heating-up temperature to reach Cause the generation of degradation product less than requiring.Analyzing reason is:First, existing combustion fan screen pack is frequently occluded, filtering Net is in order to ensure filter effect its material density very little itself, it is easy to blocks, the poor environmental condition in scene more exacerbated The blocking of filter screen;Secondly, screen pack can not on-line cleaning, existing combustion fan only has an air intake duct, and comburent air duct Interior is negative pressure, combustion fan must be stopped transport if the screen pack on cleaning air intake duct top, can not realize blower fan on-line operation When screen pack cleaning;Finally, must all stop transport combustion fan when cleaning screen pack each time, and each combustion fan is to heating The 30-42 burner supply combustion air of the floor of Duan Yige areas 6, after combustion fan is stopped transport, bringing-up section regional temperature declines rapidly, i.e., Combustion fan is set to recover to be again started up sequential and be also required to certain time at once after stopping transport, this results in cleaning screen pack each time all The larger fluctuation of whole bringing-up section temperature can be caused, this phenomenon becomes apparent when high-strength steel produces.Therefore, how combustion air is realized The on-line cleaning of the terminal fan filter screen set such as machine, turns into the task of top priority.
The content of the invention
The technical problems to be solved by the invention are to provide a kind of combustion fan that can clean screen pack automatically, can realize and help The automatic on-line cleaning of screen pack, ensures the continuity of bringing-up section temperature, reduces degradation product when firing the terminal fan operations such as blower fan Generation.
Solve above-mentioned technical problem technical scheme be:
A kind of combustion fan that can clean screen pack automatically, it is by being symmetricly set in blower fan both sides and structure identical left and right two Part form, per part include air intake duct, the screen pack for being installed on air intake duct front end, baffle plate, cylinder link mechanism, nozzle and with The water supply line of nozzle connection;Baffle plate is located inside air intake duct, by the rotating shaft and the air intake duct that are fixed on relative two sides of baffle plate Relative two side rotation connection;Cylinder link mechanism is connected with PLC control system, and connecting rod is fixedly connected with rotating shaft;Nozzle position Inside air intake duct, the water spraying direction of nozzle is towards the outside of screen pack.
A kind of above-mentioned combustion fan that can clean screen pack automatically, the air intake duct connected by tilting section with horizontal segment and Into the front end of tilting section is located at the lower section of horizontal segment, and tilting section front end is fixed with U-shaped slideway, screen pack on two relative sides It is installed in U-shaped slideway;Baffle plate is installed on the inside of horizontal segment, size and the air intake duct inner cross-sectional dimension phase of baffle plate Match somebody with somebody.
A kind of above-mentioned combustion fan that can clean screen pack automatically, the nozzle are located at close inside air intake duct tilting section At screen pack;Purge valve is installed on the water supply line.
A kind of above-mentioned combustion fan that can clean screen pack automatically, it also includes the row below air intake duct tilting section Tank.
Free-air diffuser is changed to two by the present invention by one, is divided and is listed in blower fan both sides, before two air intake duct tilting sections End is equipped with screen pack, and screen pack is entered by the U-shaped slideway of the upper and lower both sides of air intake duct and fixed, installation, convenient disassembly;It is double Air intake duct can the using and the reserved, can also use simultaneously, when side or bilateral screen pack need cleaning, it is necessary to first clean side, protect Demonstrate,prove opposite side operation, after the completion of clean opposite side again, do not allow bilateral while clean;Baffle plate is located inside air intake duct horizontal segment, It is connected by connecting rod with cylinder, cylinder is controlled by PLC, and when needing to clean the screen pack of side, cylinder, gas are controlled by PLC Cylinder promotes link motion, rotates clockwise or counterclockwise baffle plate, closes the air intake duct of the side;Then PLC control system is passed through Purge valve is opened, spraying-rinsing is carried out to screen pack by nozzle;Because nozzle is located inside air intake duct tilting section close to filtering At net, and tilting section front position is less than air intake duct horizontal segment, so the water after cleaning can be at screen pack due to Action of Gravity Field Rhone is exited into, prevents water from entering air intake duct horizontal segment and influenceing blower fan work.
Side inlet the using and the reserved during present invention work, it is assumed that prepped side is left side, right side normal operation, now by left side Switch to run by standby, cleaning right side screen pack.Left side baffle plate is opened by PLC control system first, makes left side air intake duct smooth It is logical, it is ensured that left side screen pack has been completely dried;Right-hand apron is closed by PLC control system, right side purge valve is opened, to right side Screen pack is cleaned, and the time is set as 15 minutes, and right side purge valve is closed after the completion of to be cleaned, keeps right-hand apron to close, It is more than hour to stand 5, right side can switch to stand-by state after screen pack is completely dried after right side, and arranged on left and right sides is alternately.
Beneficial effects of the present invention are:
The present invention is by changing inlet structure, setting up nozzle and the measure such as water supply line, mistake when realizing combustion fan operation The on-line auto-cleaning of filter screen, had both reduced the labor intensity of staff, and and can ensures cold rolling continuous annealing furnace bringing-up section temperature Continuity, reduce the generation of degradation product;The design of U-shaped slideway avoids the screw fixation easy stripped thread of screen pack in the prior art and led The problem of causing bolt to be fractureed by gravity, installing/dismounting is time saving, laborsaving.The present invention is simple in construction, cost is cheap, practical, tool There is wide popularizing application prospect.
