Technical field
This utility model relates to a kind of hermetically sealed pebble coal positive Pressure Transportation System device.
Background technology
Small investment, energy consumption be low and working service low cost relative to having from the point of view of ball mill for medium-speed pulverizer, thus it being subject to the widely used of major part power plant, the pebble coal processing mode that medium speed mill is produced by current coal-burning power plant mainly has: labor cleaning, scraper plate conveying, machinery transhipment and negative pressure transportation；First three processing mode causes environmental pollution relatively big, and labor strength is big, does not meets power plant safety and carries out production strictly in line with rules and regulations, and negative pressure transportation is higher to equipment requirements, and investment is big, and operation expense increases.
In addition, stone coal collecting problem produced by the construction features of medium-speed pulverizer self, always a difficult problem, stone coal collecting case small-sized, cause collecting transhipment work frequent, the amount of labour strengthens, if middling speed coal machine discharge is not in time, internal gangue dieseling also can be caused to occur, have a strong impact on the safety problem of equipment and personnel, and when coal pulverizer blowing, know from experience due to internal positive pressure gas and carry dust discharge, have a strong impact on indoor environmental hygiene.
Utility model content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of hermetically sealed pebble coal positive Pressure Transportation System device, thus solve above-mentioned technical problem.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of hermetically sealed pebble coal positive Pressure Transportation System device, including the collecting box being arranged on below medium-speed pulverizer, some drainage screens it are provided with in described collecting box, described collecting box bottom is provided with floss hole one and floss hole two, described floss hole two connects screw elevator, described screw elevator is fixedly connected with storehouse pump transmitter, described storehouse pump transmitter is fixedly connected with pipe-line system, one end of described pipe-line system connects roots blower, and the other end connection of this pipe-line system has feed bin, described feed bin is provided with sack cleaner.
Further, it is provided with air accumulator between described pipe-line system and described roots blower.
Further, pressurization making-up air device it is provided with between described pipe-line system and described feed bin.
The beneficial effects of the utility model: system fully enclosed automatic runs, environmentally safe, it is ensured that coal-burning power plant's safe and civilized production；Using positive pneumatic transport, system is less to blower fan abrasion, extension device service life.
