Abstract
The utility model discloses a kind of sack cleaner with U-tube differential manometer, its feature has be on deduster top be provided with pressure sensor and alarm lamp at two: one; Two is between deduster and induced duct, be connected with U-tube differential manometer.When in deduster, pressure reaches certain numerical value, namely pressure sensor monitors, and connects alarm lamp thereupon, and lamp one is bright, and workman just clears up dust removal and filtration bag in time, and on U-tube differential manometer, read the pressure differential between deduster and induced duct.The utility model can improve the production efficiency of sack cleaner, and can extend the service life of dust removal and filtration bag.
Description
Technical field
The utility model relates to a kind of cleaner, particularly relates to a kind of sack cleaner with U-tube differential manometer.
Background technology
Sack cleaner is industrial a kind of conventional equipment, mainly contains two kinds of purposes: one is used to dedusting and cleans, as the smoke gas treatment dedusting in iron-smelter, steel mill, Foundry Works, power plant etc.; The flue gas during smelting of aluminium electroloysis, lead, tin, zinc, copper and other rare metals filters, the recovery of superfine material; The dusts such as grain processing, flour, electron trade are administered and purification is collected; Another kind is used to collect subparticle material, and the production as SiC (carborundum) micro mist for cutting polysilicon chip is collected.For making the polysilicon chip thickness normally 150-200 μm of solar cell, in order to obtain higher rate in blocks, thinner to the SiC particle requirement being used for cutting polysilicon chip, for 1000-1500 order, producing SiC micro mist generally uses raymond mill levigate, micro powder granule diameter little to 1000-1500 order time, collect SiC micro mist only reliable sack cleaner collect.
Sack cleaner (also claiming filtration dust catcher) is a kind of dry type high efficiency deduster, it is the dust arrester utilizing fiber textile to make, its action principle is: containing the gas of subparticle under suction function, gas is drawn out of by cloth bag filter cloth, and the subparticle in gas attempt by during cloth bag filter cloth and cloth bag fiber cloth collide and be blocked, if subparticle particle diameter is large in gas, than great, then because the effect of gravity settles down, fall into ash bucket (or being feed bin), if subparticle particle diameter is little in gas, proportion is little, then be adsorbed on cloth bag filter cloth.
Produce SiC micro mist with raymond mill, use pulsed circle pouch-type dedusting filtering bag.If cloth bag filter cloth is long for service time one, SiC micro mist gathers at cloth bag filter cloth surface, when the pressure differential of filter cloth both sides is very large, can the subparticle extruding be attached on filter cloth in the past, dust collector efficiency be declined.In addition, the too high meeting of the resistance of deduster makes the air quantity of duster system significantly decline.Therefore, after the resistance of deduster reaches certain numerical value, filter cloth deashing to be given in time.
When to give filter cloth deashing, prior art be direct labor by rule of thumb.Some direct labor sees unit interval SiC micro mist production declining, then carry out a deashing, this in fact have impact on the production efficiency of sack cleaner, and not in time, deashing number of times has lacked deashing; Once, the number of times of deashing is too many, often shuts down, both have impact on the production efficiency of sack cleaner, accelerate again the damage of cloth bag filter cloth for the deashing at regular intervals that some direct labor fixes.
Summary of the invention
The utility model provides a kind of sack cleaner, especially for the sack cleaner of the band U-tube differential manometer of production SiC micro mist.The utility model solves existing sack cleaner and does not know when need the problem to cloth bag filter cloth deashing.
For solving the above-mentioned defect problem of prior art, the utility model adopts following technical scheme: a kind of sack cleaner with U-tube differential manometer is made up of induced duct, control valve, air-introduced machine, dust removal and filtration bag, feed bin etc., it is characterized in that: the access of U-tube differential manometer one end connects induced duct tracheae and is connected with induced duct, same termination enters to connect deduster tracheae and is connected with deduster, and pressure sensor and alarm lamp are contained in the middle and upper part of deduster.
According to the sack cleaner of the band U-tube differential manometer in claims described in 1, it is characterized in that: connecting induced duct tracheae is insert from U-tube differential manometer with one end with being connected deduster tracheae, pressure sensor is arranged on the middle and upper part of deduster outside, and alarm lamp is connected with pressure sensor by wire.
The beneficial effects of the utility model are: one, alarm lamp one is bright, direct labor with regard to timely deashing, task clear and definite; Alarm lamp does not work, and direct labor does not need deashing, and sack cleaner continues to use, and can improve the production efficiency of sack cleaner like this.Two, avoid when not needing deashing and shut down deashing.If frequent shutdown deashing, both fragile filter clothes, can affect again the production efficiency of sack cleaner.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model.
1 be deduster, 2 being induced duct in figure, 3 being control valve, 4 be air-introduced machine, 5 be U-tube differential manometer, 6 being alarm lamp for connecting induced duct tracheae, 7 for connecting deduster tracheae, 8,9 be pressure sensor, 10 be feed bin, 11 be dust removal filter, 12 be deduster import.
Detailed description of the invention
Below in conjunction with accompanying drawing, specific embodiment of the utility model and technology contents are further described.
As shown in Figure 1: the sack cleaner that the utility model relates to the band U-tube differential manometer producing SiC micro mist with raymond mill, deduster 1 top is connected with induced duct 2, air-introduced machine 4 is used for extracting the air in deduster 1, make to produce negative pressure in deduster 1, the size of negative pressure is regulated with the control valve be connected on induced duct 2 by the rotating speed of air-introduced machine 4; In deduster 1, there are many dust removal and filtration bags 11 room, and the gas (raw material) containing SiC micro mist is admitted in deduster 1 from the deduster import 12 deduster 1.Because of suction function, be admitted to colliding on dust removal and filtration bag 11 containing the particle in SiC micro mist gas in deduster 1, fine SiC micro powder granule is adsorbed on dust removal and filtration bag 11, and larger SiC micro powder granule then falls into feed bin 10 because of collision.Feed bin 10 is used for storing SiC micro mist, and when clearing up dust removal and filtration bag 11 at set intervals, feed bin 10 also fallen into by the SiC micro mist on dust removal and filtration bag 11.U-tube differential manometer 5 upper end is connected with two tracheoles, one is connect airduct tracheae 6, another root connects deduster tracheae 7, connecting airduct tracheae 6 is connected between U-tube differential manometer 5 and deduster 1, connecting deduster tracheae 7 is connected between U-tube differential manometer 5 and induced duct 2, pressure differential between deduster 1 and induced duct 2, U-tube differential manometer 5 can read.Pressure sensor 9 is arranged on the top outside deduster 1, alarm lamp 8 is connected with pressure sensor 9 by wire, when pressure sensor 9 monitors pressure in deduster 1 to certain numerical value, alarm lamp 8 is switched on to be lighted, and means and informs this cleaning dust removal and filtration bag 11 of direct labor.
The sack cleaner of prior art, does not connect U-tube differential manometer 5 and pressure sensor 9 and alarm lamp 8, when clears up dust removal and filtration bag 11 and entirely estimate by knowhow, too early or cross the production efficiency that late Qing Dynasty reason dust removal and filtration bag 11 all can affect deduster 1.The utility model structure is comparatively scientific and reasonable, can improve the production efficiency of sack cleaner and extend the service life of deduster filter bag 11.
