Description
Technical field
The utility model relates to the device in a kind of solid material conveying technology field, specifically a kind of pair of force feed delivery system.
Background technology
Two pressure bull ladles send two kinds of formulas containing pressure sending type and suction, and positive-pressure pneumatic is carried and negative-pressure pneumatic mode of movement, send equipment to be jointly arranged on a truck chassis conveying batch can and force feed, suction and have just formed force feed tank car, as bulk cement carrier; Inhale tank sending car, as dust collector automobile and two pressure waggon, they can realize remote clean the transporting of bulk cargo within the specific limits.
Force feed tank car mode is loose unpacked material to be fallen into conveying batch can naturally from eminence accepting material end (storage end), then garage is sailed to and discharge material end (exhaust end), connect flexible pipe, material is entered in the sealing feed bin with dust exhaustor by pressurized air.This mode, because storage end is unlimited open to atmosphere, easily causes airborne dust and pollution.
Inhaling tank sending car mode is vacuum pump, engine installation and the isolated by filtration system etc. of using dust collector automobile to carry, utilize negative pressure, by flexible pipe, the loose unpacked material of storage end is sucked and carries batch can, then garage is sailed to discharge place, open tail-gate, material is toppled over and drawn off, and this mode can cause secondary pollution when discharge.
Two pressure waggons are to integrate above-mentioned two kinds of modes, utilize pressurized air that the transmitting bulk material of storage end is arrived to batch can, then garage are sailed to exhaust end, connect flexible pipe, and material is entered in the sealing feed bin with dust exhaustor by pressurized air.This mode has solved the secondary pollution problem of above-mentioned two kinds of modes, but because equipment is complicated, expensive, popularize and acquire a certain degree of difficulty.
The whole working processs of two pressure waggons carry out under fully enclosed state, and do not run and emit, drop, be the necessary equipment of factory's cleaner production.Suction vehicle application is very extensive, in steel plant, and cement mill, chemical plant, mining sites etc. are located widespread use, apply the most ripe steel plant that surely belong to.The environment at position and the particulate dust transhipment work of craft dust removal ash such as suction vehicle is mainly under the blast furnace gravity, dry method, stokehold, groove of acknowledgement of consignment steel plant ironmaking, sintering, steel-making, coking.When vehicle arrives filler bin, start vehicle unit of vacuum material-suction system, the Feed system by surface facility sucks material in vehicle-mounted carrying tank; When vehicle arrives while connecting material storehouse, start vehicle pressure system, the system that connects material by surface facility by the material pressure in vehicle-mounted carrying tank body in the storehouse that connects material.The processes such as whole suction, transportation, discharge are all carried out under airtight condition, and dust does not leak and flies upward, and save the energy, meet International Environmental Protection standard.
Through the inspection of prior art is found, Chinese patent literature CN1807208B, open day 2006-07-26, discloses a kind of double-pressurized delivery vehicle mounted pneumatic delivery method and equipment thereof, and this technology packs material in airtight container into; Adopt pressurized air under sealing state by material from airtight container is sent to the major ingredient tank of carrying tank car, in tank, carry out material and air separation process; Transfer pot garage is sailed to exhaust end; Under sealing state, by pressurized air, material is entered in the sealing feed bin with dust exhaustor.Equipment comprises conveying tank car, carry tank car to there is car chassis and be arranged at major ingredient tank above it, by filter chamber's access valve and the tank connected filter chamber of major ingredient, manifold valve block, be arranged at the fluidizer of major ingredient tank tail end and supply compressed-air actuated air compressor, major ingredient tank is connected with feeding equipment by flexible pipe, and fluidizer is connected with discharge apparatus by discharge flexible pipe.But this technology waggon bag dust collector, filter efficiency is lower, and concentration of emission is high, and maintenance and maintenance intervals are long, and expense is high; Waggon has major ingredient chamber, cloth bag chamber (or auxiliary material chamber) to form complex structure, processing and manufacturing and installation integrated complex, manufacturing cycle is long, and cost is high, and lower because have major ingredient chamber, cloth bag chamber (or auxiliary material chamber), auxiliary tank to form effective volume or the internal dimensions of the loading space of main tank.
