Abstract
The utility model relates to a deflector for the bag cage of a filter bag, which belongs to the technical field of bag type dust collectors and aims to provide the deflector for the bag cage of the filter bag, which can replace a jacket and a Venturi tube and can ensure the filter area of the filter bag, reduce equipment running resistance and protect the bag mouth from excessive scour. The utility model has the technical points that the deflector (3) is in a barrel shape rolled by a thin steel plate; a barrel (31) is provided with a plurality of circles of U-shaped deflector holes (32) from top to bottom from outside to inside, wherein each circle is provided with multiple U-shaped deflector holes with upward openings, and the thin steel plate preserved above the U-shaped deflector holes is upwards bent to form U-shaped fish scale-shaped flow deflectors (33).
Description
Technical field
The utility model relates to a kind of guiding device that is used for filter bag bag cage, belongs to the sack cleaner technical field.
Background technology
The long bag of low pressure arteries and veins spray deduster with its high filtration velocity, can handle high dust-laden, technical advantages such as air quantity gas greatly, be used widely in the industrial dedusting field.During such deduster deashing, the deashing source of the gas by injection hole ejection and induce the air-flow that produces to enter filter bag by the filter bag opening center.For reducing deashing air-flow washing away to filter bag, the energy exchange of more effective promotion source of the gas and induced draft, the measure of taking at present mainly is included in a bag cage sack position and the sack sheath is set or in the following bag cage of card Venturi tube is installed, but problems such as filter area reduces, the equipment running resistance increases and the deashing airflow kinetic energy is weakened that the two all unavoidably exists, especially influence is particularly evident when handling big air quantity flue gas.
Summary of the invention
The utility model purpose is the deficiency at prior art, provides a kind of and can substitute sheath and Venturi tube, and can guarantee the filter bag filter area, reduces the equipment running resistance, protects sack to avoid the guiding device that is used for filter bag bag cage that excessively washes away.
Its technical scheme is: a kind of guiding device that is used for filter bag bag cage, it is characterized in that: the tubular of this guiding device for rolling by sheet metal, cylindrical shell, outside in offers the U-shaped pod apertures that multi-turn, a plurality of openings of every circle make progress from top to bottom, and the sheet metal that retain U-shaped pod apertures top upwards is bent to form the cataphracted flow deflector of U-shaped.
Its beneficial effect is: alternative sheath of this guiding device and Venturi tube are placed the interior top of bag cage, when the deashing air-flow directive filter bag of injection hole ejection is run into the cataphracted flow deflector of guiding device U-shaped, the process that air-flow has a contraction to expand again, flow deflector has played with Venturi tube and has similarly induced ejector action, has promoted the energy exchange between source of the gas and induced draft; Simultaneously, the setting of this guiding device has also avoided because the position deviation that may cause in the nozzle installation process, and the deashing air-flow that causes deflection causes excessively the washing away of sack position, and has prolonged the service life of filter bag; In addition, the U-shaped pod apertures of offering on this guiding device makes ash-laden gas filter through filter bag, enters the effective filtration area of also having guaranteed filter bag in the bag by pod apertures, and enter of the cancellation of the interior purifying gas flow of bag, and effectively reduce the running resistance of equipment owing to Venturi tube.
Description of drawings
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the vertical view of Fig. 1;
Fig. 3 is the expansion schematic diagram of guiding device;
Fig. 4 is provided with schematic diagram for pod apertures and flow deflector.
The specific embodiment
Shown in Fig. 1,2,3,4, the tubular of guiding device 3 for rolling by sheet metal, cylindrical shell 31, outside in offers the U-shaped pod apertures 32 that multi-turn, a plurality of openings of every circle make progress from top to bottom, and the sheet metal that retain U-shaped pod apertures top upwards is bent to form the cataphracted flow deflector 33 of U-shaped.The flow deflector upwards angle of bending is the 30-60 degree, and the upwards bending angle of its best is 45 degree.
The position of two adjacent circle U-shaped pod apertures 32 is for being crisscross arranged on the above-mentioned cylindrical shell.
The length of U-shaped pod apertures 32 openings that the every circle upper shed of above-mentioned cylindrical shell makes progress prolongs from top to bottom successively, and the sheet metal that makes the pod apertures top retain upwards is bent to form the cataphracted flow deflector 33 of U-shaped, also prolongs successively from top to bottom thereupon.
During use, this guiding device 3 is placed top in bag cage 1, its top is fastened on the card 5 by CAP NUTS 2.
Claims (4)
1. guiding device that is used for filter bag bag cage, it is characterized in that: the tubular of described guiding device (3) for rolling by sheet metal, cylindrical shell (31), outside in offers the U-shaped pod apertures (32) that multi-turn, a plurality of openings of every circle make progress from top to bottom, and the sheet metal that retain U-shaped pod apertures top upwards is bent to form the cataphracted flow deflector of U-shaped (33).
2. the guiding device that is used for filter bag bag cage according to claim 1 is characterized in that: what described flow deflector (33) upwards bent is 45 degree.
3. the guiding device that is used for filter bag bag cage according to claim 1 is characterized in that: described cylindrical shell (31) is gone up the position of two adjacent circle U-shaped pod apertures (32) for being crisscross arranged.
4. the guiding device that is used for filter bag bag cage according to claim 1 is characterized in that: the length of U-shaped pod apertures (32) opening on the every circle of described cylindrical shell (31) prolongs from top to bottom successively.
