Keywords and boolean syntax (USPTO or EPO format): seat belt searches these two words, or their plurals and close synonyms. "seat belt" searches this exact phrase, in order. -seat -belt searches for documents not containing either word.
For searches using boolean logic, the default operator is AND with left associativity. Note: this means safety OR seat belt is searched as (safety OR seat) AND belt. Each word automatically includes plurals and close synonyms. Adjacent words that are implicitly ANDed together, such as (safety belt), are treated as a phrase when generating synonyms.

Technical field
The utility model relates to gluing short fiber and produces drying sludge air-flow cyclone dust collector, and it is to be a kind ofly used for separated gluing short fiber and to produce the chemical industry equipment of fine dusts in drying sludge flow of process air, belongs to chemical industry equipment field.
Background technology
Deduster is the equipment that dust is separated from flue gas, in gluing short fiber production process, can give off a large amount of acidic and alkaline wastewaters, waste water is after super-dry is processed, use a large amount of hot air seasonings, hot gas is used for drying after mud, in hot gas, still contain a large amount of heats, directly be discharged in atmosphere, cause thermal waste, conventionally after hot gas will being transferred to heat exchanger again and heating, hot gas reaches enough heat energy deposits, can again be used for drying mud, hot gas is after mud is dried, in air, be mixed with granular mud granule, directly transfer to heat exchanger, be easy to cause heat exchanger poisoning, reduce the heat conduction of heat exchanger, so will carry out air filtration processing through drying the hot gas of mud, also do not have at present more ripe technology to carry out the mud granule in separated hot gas, deduster is when carrying out hot-air separation, also can there are problems, such as: hot-air has uptrend, be difficult to allow it separated around deduster downwards, hot-air also has buoyancy upwards to mud granule, mud granule is not easy the problems such as sinking, cause separative efficiency very low, even cannot be separated.
summary of the invention
In order to solve the problem of above-mentioned existence, the utility model discloses a kind of gluing short fiber and produce drying sludge air-flow cyclone dust collector, this gluing short fiber is produced drying sludge air-flow cyclone dust collector, mud granule in the hot gas of processing after short fiber mud can be separated, have good separating effect.
Gluing short fiber is produced drying sludge air-flow cyclone dust collector, the cylindrical shell that comprises hollow cylinder shape, the lower end of cylindrical shell is fixed with hollow cone, the osculum end of cone is downward, osculum end is ash discharging hole, the upper end sidewall of cylindrical shell is provided with air inlet pipe, the top of cylindrical shell is provided with blast pipe, the outer wall of described cylindrical shell and cone and inwall are equipped with the round projection of coiled coil, the cross section of projection is downward hangnail shape, projection is from dwindling towards top gradual change with cylindrical shell and cone fixed connection place, top is pointed, stagger mutually in the protruding position of the outer wall of cylindrical shell and cone and inwall.
Described cylindrical shell is vertical, and air inlet pipe is horizontally fixed on cylindrical shell, and the inwall of air inlet pipe and cylinder inboard wall are in tangent position.
The bottom of described blast pipe extends to inner barrel, and the bottom of blast pipe flushes with the lower horizontal line of air inlet pipe.
The utility model, simple in structure, easy to use, projection on cylindrical shell and cone outer wall can be alleviated the vibrations of deduster, projection on cylindrical shell and cone inwall can stop that hot gas rises, guiding hot gas can be close to inwall rotation and decline, and can stop mud granule floating, is conducive to successfully mud granule be discharged from ash discharging hole.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model,
Fig. 2 be the B of Fig. 1 to view,
Fig. 3 is longitudinal broken away view of the utility model barrel wall,
Reference numerals list: 1-blast pipe, 2-cylindrical shell, 3-air inlet pipe, 4,4 '-projection, 5-cone, 6-ash discharging hole.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model.Should understand the following specific embodiment and only for the utility model is described, be not used in restriction scope of the present utility model.It should be noted that, word 'fornt', 'back', " left side ", " right side ", "up" and "down" that use is described below refer to the direction in accompanying drawing, and word " interior " and " outward " refer to respectively the direction towards or away from specific features geometric center.
Visible by reference to the accompanying drawings, this gluing short fiber is produced drying sludge air-flow cyclone dust collector, the cylindrical shell 2 that comprises hollow cylinder shape, the lower end of cylindrical shell 2 is fixed with hollow cone 5, the osculum end of cone 5 is downward, osculum end is ash discharging hole 6, the upper end sidewall of cylindrical shell 2 is provided with air inlet pipe 3, the top of cylindrical shell 2 is provided with blast pipe 1, the round projection 4 and 4 ' that the outer wall of described cylindrical shell 2 and cone 5 and inwall are equipped with coiled coil, the cross section of projection 4/4 ' is downward hangnail shape, projection 4/4 ' is from dwindling towards top gradual change with cylindrical shell 2 and cone 5 fixed connection places, top is pointed, stagger mutually in the position of the outer wall of cylindrical shell 2 and cone 5 and the projection of inwall 4 and 4 '.The utility model, simple in structure, during use, the hot gas that contains mud granule enters cylindrical shell 2 fast from air inlet pipe 3, hot gas spirals along cylindrical shell 2 inwalls, and move down under Action of Gravity Field, in hot gas is transferred to cone 5, mud granule drops down from ash discharging hole 6, the circular motion track of hot gas diminishes, linear velocity is accelerated, and move upward in cone 5 lower end convolutions, center line through cylindrical shell 2 is discharged from blast pipe 1, particle in Exhaust Gas greatly reduces, when the gas of discharging carries out heat exchange increase heat energy, can avoid heat exchanger to damage.
Described cylindrical shell 2 is vertical, and air inlet pipe 3 is horizontally fixed on cylindrical shell 2, and the inwall of air inlet pipe 3 and cylindrical shell 2 inwalls are in tangent position.The position of tangent line is conducive to gas and keeps higher pace.
The bottom of described blast pipe 1 extends to cylindrical shell 2 inside, and the bottom of blast pipe 1 flushes with the lower horizontal line of air inlet pipe 3.From bottom, upwards the dust content of the thermal current core of operation is minimum, from blast pipe 1, discharges, and air-flow surrounding contains can not discharging from blast pipe 1 of dust granule, is trapped within cylindrical shell top, the slowly sedimentation under Action of Gravity Field automatically of the particle in gas.
The disclosed technological means of the utility model scheme is not limited only to the disclosed technological means of above-mentioned technological means, also comprises the technical scheme being comprised of above technical characterictic.
