A filtering barrel is arranged in a filtering barrel body; a sweeping plate and a sweeping steel brush are mounted on a center rotating shaft in the middle; a lower tapered body with a manual-draining ball valve is arranged at the bottom of the filtering barrel body; a tapered material scraper sleeved on the center rotating shaft is arranged in the lower tapered body; two opposite discharge ports and support legs are arranged outside the lower part of the filtering barrel body; two opposite feed ports are formed in the upper part of the filtering barrel body; a control box is arranged outside the middle of the two feed ports; a sealing head fixed by a flange is arranged at the top of the filtering barrel body; an exhaust port and a reverse-blowing washing port are formed in two sides of the sealing head; a rack is arranged above the sealing head; and a shaft coupler, a speed reducer and a motor are arranged at the middle of the sealing head from bottom to top. The filtering device can be used for effectively screening oversized particles in coal water slurry, so that when the filtering, the cleaning and the sewage draining are performed, and the operation that the filtering device is disassembled in a shutdown manner is not required. Therefore, the fully-automatic running is realized.
Description
Technical field
The utility model relates to a kind of coal slurry filter, especially full-automatic coal slurry filter.
Background technology
Water-coal-slurry is a kind of generation oil fuel, with real oil fuel big difference is arranged still very much, problem such as especially water-coal-slurry slagging scorification when using, knot ash, wearing and tearing and must corresponding configuration remove the gred, blow devices such as ash, dedusting, so the filtering technique of studying water-coal-slurry is even more important.The Energy Situation of the rich coal of China, oil-poor, weak breath has determined that replace oil with coal is the main direction of China's energy development.
At present, China's coal water slurry gasification device all adopts full overflow type bar type coal pulverizer directly to drive the circular drum sieve structure, the circular drum sieve is 3.5mm by the gap, if enlarged rounded rotary screen grating gap, improved coal pulverizer efficient and promoted coal-water fluid concentration, and then improved the gasification efficiency of gasification furnace, for the gasification installation that needs water-coal-slurry 4000m3/h every day, can increase economic efficiency every day more than 100,000, annual economic benefit is considerable.Yet bulky grain coal slurry particle is directly entered by rotary screen in the burner of gasification installation, stop up the gasification burner tip runner, cause gasification installation to stop, lose huge; If keep circular drum sieve grating gap constant, be unfavorable for that then coal slurry improves concentration, gasification efficiency greatly reduces, and also can produce huge waste simultaneously.Just be based on this present situation, make new automatic efficient coal slurry filter can guarantee the high-efficiency and continuous operation, large granule more than the diameter 3.5mm in the water-coal-slurry is effectively sieved, be conducive to improve water coal slurry concentration and then promote gasification efficiency, the gasification installation of avoiding bulky grain in the coal slurry that the obstruction of gasification burner tip runner is caused simultaneously stops.
Summary of the invention
In order to overcome the in-problem deficiency of prior art; the utility model provides a kind of novel full-automatic coal slurry filter, and this full-automatic coal slurry filter effectively sieves the large granule in the water-coal-slurry; filter when cleaning blowdown, need not to shut down the dismounting filter.Can make automatically controlledly to combine with mechanical part, realize fully automatic operation.
The technical scheme that its technical problem that solves the utility model adopts is: full-automatic coal slurry filter, formed by motor, reductor, frame, shaft coupling, blowback rinse mouth, end socket, control cabinet, charging aperture, filtration barrel body, filter cylinder, cleaning steel brush, discharging opening, hypocentrum, supporting leg, manual blowdown ball valve, taper material scraper, cleaning board, centre rotational axis, exhaust outlet, there is filter cylinder the inside of filtration barrel body, there is centre rotational axis the centre, and cleaning board and cleaning steel brush are housed on the centre rotational axis; The hypocentrum that has the manual blowdown ball valve is arranged at the bottom of filtration barrel body, and there is the taper material scraper that is enclosed within on the centre rotational axis the inside of hypocentrum; There are two relative discharging openings filtration barrel body bottom outside, supporting leg is arranged below the filtration barrel body; Two relative charging apertures are arranged at the top of filtration barrel body, and there is control cabinet the outside in the middle of two charging apertures; The end socket that the useful flange in filtration barrel body top is fixing, there are exhaust outlet and blowback rinse mouth in both sides on the end socket.Shaft coupling, reductor, motor are arranged in the middle of the organic frame above the end socket, end socket from bottom to top.
This full-automatic coal slurry filter is a kind of the filtration and the filter that cleans synchronous realization.Filter cylinder adopts high-intensity wedge shape filter screen, have characteristics such as filter area is big, precision is high, easy cleaning, motor drives cleaning device by cycloidal planetary gear speed reducer, and cleaning device is with the contaminant removal of filter inner accumulated in screen surface, and impurity drops in the lower cone of filtration barrel body bottom.When bottom impurity gathers when too much needing blowdown; need not to shut down the full-automatic coal slurry filter of dismounting; as long as open manual ball valve; utilize the brush control device of filter cylinder pressure reduction of inside and outside moment and a cover rotation, impurity is drained by the manual blowdown valve, the time of whole cleaning process is according to how many controls arbitrarily of impurity content; in whole cleaning process, can not stop; institute's water requirement is few during cleaning, even under critical pressure, excellent cleaning effect is arranged also.
Full-automatic coal slurry filter, the field control case of composition such as import and export Pressure gauge and differential manometer is fixed on the filter cylindrical shell, in PLC is housed, the effective monitoring to the coal slurry filter is realized in the programming back, the normal operation of assurance coal slurry filter.
The beneficial effects of the utility model are, this full-automatic coal slurry filter, (1) large granule in the water-coal-slurry is particularly effectively sieved more than the diameter 3.5mm, be conducive to improve water coal slurry concentration and then promote gasification efficiency, the gasification installation of avoiding bulky grain in the coal slurry that the obstruction of gasification burner tip runner is caused simultaneously stops.(2) filter cleaning and carry out simultaneously, when needing the cleaning blowdown, need not to shut down the full-automatic coal slurry filter of dismounting.(3) automatically controlled part adopts Programmable Logic Controller, makes automatically controlledly to combine the realization fully automatic operation with mechanical part.
