Description
Technical field
The utility model relates to fixed-bed type coal gas field, is specifically related to a kind of moulded coal screening closed conveying re-use device.
Background technology
Current Ammonia Production industry adopts moulded coal to be raw material, syngas for synthetic ammonia is produced by fixed level gas cooker, after moulded coal goes out vibratory sieve, the coal dust produced in transport, shunting, discharge process is at about 8-10%, if unscreened coal dust enters gas burner, there is impact in various degree to the resistance, carry-over, consumption etc. of gas burner.In addition, vibratory sieve smalls need be transported to moulded coal process units recycling by multiple stage motor vehicle, and in transport process, dust is large, site environment is poor, and greatly, maintenance cost is high for motor vehicle wearing and tearing and oil consumption.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of moulded coal screening closed conveying re-use device, the coal dust that moulded coal can be produced in transportation after screening closed conveying to briquette production line cycling and reutilization.
For solving the problems of the technologies described above, the technical scheme that the utility model adopts is: a kind of moulded coal screening closed conveying re-use device, involving vibrations sieves, the exit, lower end of vibratory sieve is provided with coal conveyer belts, the first coal powder collection bucket is provided with below the screen cloth of vibratory sieve, coal conveyer belts is provided with electric plough type unloading apparatus, the below of coal conveyer belts is provided with the feed bin corresponding with electric plough type unloading apparatus, the exit of feed bin connects slide sieve, feed bin and slide sieve junction are provided with push-pull valve, the second coal powder collection bucket is provided with below the screen cloth of slide sieve, wherein the outlet of the first coal powder collection bucket and the second coal powder collection bucket is all connected to embedded scraper transporter.
The screen cloth spacing of described vibratory sieve and slide sieve is 9-12mm.
The screen area of described slide sieve is 0.5-1m
2.
Described push-pull valve is hydraulic pressure push-pull valve.
Described moulded coal is after vibratory sieve and the screening of slide sieve secondary grading, coal dust enters embedded scraper transporter by the first coal powder collection bucket and the second coal powder collection bucket, be delivered to briquette production line recycling through its airtight step, moulded coal can directly enter firing machine for subsequent use after slide sieve screening.
The moulded coal screening closed conveying re-use device that the utility model provides has following beneficial effect:
1, between feed bin and automatic stoker, establish slide sieve, coal dust is screened before gas generator mouth, produce bed resistance after avoiding coal dust to enter gas burner, affect the operational efficiency of gas burner.
2, the moulded coal after screening enters that ashes divide less, epigranular, and in gas burner, gasification layer permeability is better, reduces ton ammonia feed coal and consumes.
3, total closed type automatic transport, realizes coal dust transhipment recycling, greatly improves site environment, reduce engine motor-car and cleaner consumption.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
As shown in Figure 1, the utility model involving vibrations sieve 1, the exit, lower end of vibratory sieve 1 is provided with coal conveyer belts 2, the first coal powder collection bucket 3 is provided with below the screen cloth of dynamic sieve 1, coal conveyer belts 2 is provided with electric plough type unloading apparatus 4, the below of coal conveyer belts 2 is provided with the feed bin 5 corresponding with electric plough type unloading apparatus 4, the exit of feed bin 5 connects slide sieve 6, feed bin 5 and slide sieve 6 junction are provided with push-pull valve 7, the second coal powder collection bucket 8 is provided with below the screen cloth of slide sieve 6, wherein the outlet of the first coal powder collection bucket 3 and the second coal powder collection bucket 8 is all connected to embedded scraper transporter 9.
The screen cloth spacing of described vibratory sieve 1 and slide sieve 6 is 9-12mm.
The screen area of described slide sieve 6 is 0.5-1m
2.
Described push-pull valve is hydraulic pressure push-pull valve.
The oven dry moulded coal come by briquette production line, after vibratory sieve primary screening, coal dust falls into the first coal powder collection bucket through screen cloth and enters embedded scraper transporter, the moulded coal of granularity >=10mm exports to For Gas-making Process coal conveyer belts through vibratory sieve, coal conveyer belts is provided with electric plough type unloading apparatus, by discharger, moulded coal is entered feed bin, bin outlet is provided with push-pull valve, after push-pull valve, slide sieve is set, moulded coal is in discharging, in push-pull valve opening-closing process, the coal dust produced falls into the second coal powder collection bucket through postsearch screening and enters embedded scraper transporter, gas generator is entered after granularity >=10mm moulded coal to firing machine, moulded coal is through first and second screening, and coal dust is transported to briquette production line through embedded scraper transporter automatic step when airtight, is transported to raw coal storehouse for subsequent use with raw coal after stirring by discharging belt conveyer.
