Abstract
The utility model relates to a coal adding device for a gas furnace. The coal adding device comprises a seal valve at the top of the gas furnace, a gate valve and a coal bin above the gate valve. The coal adding device is characterized in that the seal valve is connected with a coal adding seat plate valve and a filtering device arranged between the coal adding seat plate valve and the gate valve. The filtering device comprises a slide sieve short joint, a cover plate, a slide sieve box, an escape pipe, a slide sieve, a powdered coal bucket, a discharging pipe and a quick-open gate. According to the utility model, the filtering device is arranged below the gate valve so that most of powered coal in the raw material coal is removed by the filtering device and most of coal entering the furnace meets the process requirement of coal as fired; and leakage can be effectively avoided in an operating process.
Description
Technical field
The utility model relates to the coal supply apparatus of a kind of coal supply apparatus, particularly a kind of gas furnace.
Background technology
Present most of Gas-making Furnace coal system adds push-pull valve up and down at the coal apparatus for temporary storage, is made up of seal valve under the push-pull valve.Yet owing in feed coal, contain the undesirable coal dust of a lot of particle diameters, not only be prone to make push-pull valve stuck, leakage phenomenon to occur, and coal dust gets into and also be prone to cause the gas furnace uneven phenomenon that gasifies behind the gas furnace, influence the working of a furnace.
The utility model content
The utility model technical problem to be solved provides a kind of difficult leakage and effectively removes the device of coal dust in the feed coal.
In order to solve the problems of the technologies described above, the utility model adopts following technical scheme:
A kind of coal supply apparatus of gas furnace comprises the seal valve, push-pull valve of coal gas furnace roof and the coal bunker of push-pull valve top, it is characterized in that connecting the coal base-plate valve on the seal valve, between coal base-plate valve and push-pull valve, being provided with filtration unit.
Said filtration unit comprises slide sieve short circuit, cover plate, slide sieve casing, blow-down pipe, slide sieve, fine coal coal bunker, tremie pipe and opens plate soon.
Said slide sieve short circuit is connected with the coal base-plate valve.
Said blow-down pipe is located at the top of slide sieve casing.
Saidly open the bottom that plate is located at tremie pipe soon.
Design filtration unit under push-pull valve, and change the push-pull valve under the filtration unit into base-plate valve, and realize that through changing the program control time operation of coal system is normal.
Temporary place changes a filtration unit into original coal, and design slide sieve in filtration unit the inside is removed the coal dust that does not meet the particle diameter requirement.After the feed coal of certain grain size gets into filtration unit from coal bunker through push-pull valve; Be provided with a slide sieve in the filtration unit the inside; And slide sieve can be set different in width as required, and the coal dust that comes out through the slide sieve after-filtration falls in the coal dust coal bunker, and has set up one to drive push-pull valve soon in coal dust coal bunker bottom; After the coal dust in the coal dust coal bunker is deposited some amount, get rid of through driving push-pull valve soon.
Traditional push-pull valve is replaced the leakage in the time of effectively to prevent to move with base-plate valve.
This practical coal method through increase filtration unit under push-pull valve, makes that most coal dust is got rid of through filtration unit in the feed coal, makes the coal overwhelming majority that gets in the stove can meet the processing requirement into the stove coal.And effectively prevent the leakage that occurs in the operational process.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is done further explain.
Fig. 1 is the structural representation of stoker.
Fig. 2 is the slide sieve structural representation.
Wherein, Reference numeral: 1 is seal valve, 2 coal base-plate valves, and 3 is the slide sieve short circuit, 4 is cover plate, 5 slide sieve casings, 6 is blow-down pipe, and 7 is push-pull valve, and 8 is coal bunker, and 9 is slide sieve, and 10 is the fine coal coal bunker, and 11 is tremie pipe, and 12 for drive push-pull valve soon.
Embodiment
As depicted in figs. 1 and 2; The utility model discloses a kind of coal supply apparatus of gas furnace; The coal bunker 8 that comprises seal valve 1, push-pull valve 7 and push-pull valve 7 tops of coal gas furnace roof 1 connects coal base-plate valve 2 on the seal valve, between coal base-plate valve 2 and push-pull valve 7, is provided with filtration unit.Said filtration unit comprises slide sieve short circuit 3, cover plate 4, slide sieve casing 5, blow-down pipe 6, slide sieve 9, fine coal coal bunker 10, tremie pipe 11 and opens plate 12 soon.Wherein slide sieve short circuit 3 is connected with coal base-plate valve 2, and blow-down pipe 6 is located at the top of slide sieve casing 5, opens the bottom that plate 12 is located at tremie pipe 11 soon.
Feed coal gets into slide sieve and filters through push-pull valve 7 during work, and in the stream sieve, stores, and after valve 1 to be sealed is opened 1～1.5 second, opens stoker base-plate valve sieve 1～1.5 second, adds temporary coal in the slide sieve casing in the stove.And the per 1～2h of coal through getting into the coal dust coal bunker after the filtering system drives push-pull valve soon and emits through opening.In the coal process, the steam that adds Gas-making Furnace can get in the coal pipeline through seal valve and base-plate valve, solves this problem so on filtration unit, add exhaust-valve.
The above is merely the preferred embodiment of the utility model; Not in order to restriction the utility model; Any modification of being done within all spirit and principles at the utility model, be equal to replacement and improvement etc., all should be included within the protection domain of the utility model.
