Description

The microkinetic belt cleaner

Technical field

The utility model relates to cleaner, is specifically related to a kind of belt cleaner.

Background technology

At present in various treating flour dust work; The environmental pollution that coal preparation technique system of coal preparation plant causes in the defeated coal and the process of unloading coal is very serious; Be characterized in that points of contamination is many, pollution sources disperse, area is big and the control difficulty is big, belt carries site space narrow and small, difficult in maintenance etc.; Dust pollution directly influences the safe operation of environment and equipment, endangers operating personnel's physical and mental health simultaneously, is the long-standing of efforts at environmental protection.

Summary of the invention

Goal of the invention: the purpose of the utility model is to overcome the deficiency of above-mentioned prior art, and a kind of microkinetic, no occupation of land, cost, good dedusting effect, novel belt cleaner that the maintenance maintenance workload is little are provided.

Technical scheme: in order to solve the problems of the technologies described above, the described microkinetic belt cleaner of the utility model, it comprises filter chamber and air-purifying chamber; Said filter chamber and air-purifying chamber are separated by card, in said filter chamber, are provided with filter bay assembly, are provided with the dust-contained airflow inlet in bottom, said filter chamber; Be provided with the pulse jet system in said air-purifying chamber one side outside; Be provided with the pure qi (oxygen) outlet at said air-purifying chamber opposite side, below this pure qi (oxygen) outlet, be provided with off-line equipment, the advantage of off-line equipment is; Filter bag deashing under off-line state is more thorough, and the dust of the clear rosy clouds of assurance winding-up can not reverted to take drugs by secondary before falling.

It is inner that said filter bay assembly is vertically mounted on said filter chamber, helps dust absorption and deashing, and owing to the shake of filtrate when deashing is less, prolong the service life of filter bag, and operating cost reduces.

Said pulse jet system comprises electromagnetic impulse valve, and gas bag and instrument adopt locellus type jetting deashing technology, and pulse valve bag chamber of can jetting is simultaneously reduced the quantity of pulse valve widely, reduces fittings cost, saves the compressed air consumption.

On said card, be provided with circular hole, said filter bay assembly is through this circular hole said filter chamber of packing into, and said card is used to support filter bag and separates filter chamber's (dust-laden section), air-purifying chamber.

Said filter bay assembly adopts terylene three anti-Nomex materials, good springiness, and intensity is high, makes the fabulous dust-separation of filter chamber and air-purifying chamber, and good seal performance effectively prevents the phenomenon of dust explosion to take place; On filter bag and the card short tube be connected the fixture that adopts special substance, when guaranteeing negative pressure work, the sealing of filter bag makes things convenient for the replacing of filter bag simultaneously again; Filter bag fixedly cage is used for fixing the bottom of filter bay assembly, prevents filter bag rolling dynamic friction.

This equipment partly is made up of air-purifying chamber, filter chamber and pulse dust cleaning system etc.; Dusty gas is under the effect of system's main air blower; Get into the deduster filter chamber from the band machine; Dust is adsorbed on the outer surface of filter bag, and the clean gas after the filtration sees through filter bag and gets into the pure qi (oxygen) system and be collected to pure qi (oxygen) outlet discharge; Continue along with filtering operating mode; Accumulate in dust on the filter bag outer surface with cumulative, the corresponding running resistance that will increase equipment is in order to guarantee the normal operation of system; Must carry out filter bag ash removal regeneration; Send instruction by special-purpose pulse automatic controller through fixed resistance or timing this moment, and pulse valve is started working, and carries out deashing.

Filter chamber in this equipment is divided into two independent case chambers, on the pure qi (oxygen) exit passageway, is provided with off-line equipment, has realized off-line ash-clearing, off-line maintenance function; When having overcome original dust pelletizing system " online ash removal "; The clear dust down of adjacent work filter bag absorption increases the drawback that adjacent filter bag is loaded, simultaneously; Dust is controlled in the sealed space all the time, can not produce secondary pollution.

In addition, this device can also be set up sprayer unit according to user's requirement.Sprayer unit mainly is made up of ceramic atomizer, humidity measurement instrument and electric control gear etc.Atomizer is installed in easy generation dust parts such as place, material whereabouts, chicane, can improve the relative humidity of dust laden air, not only plays the depositing dust effect, can also prevent kicking up of dust; During work, when the humidity of dust laden air reached preset critical numerical value, humidity measurement instrument just passed to electric control gear with signal, and nozzle is promptly started working, and when humidity reached preset certain numerical value, nozzle promptly quit work; Package unit moves automatically, need not special messenger's operation, and the critical numerical value of humidity can be set arbitrarily as required fully; The operation of complete equipment can be controlled by electrical control cubicles.

Beneficial effect: the utility model compared with prior art, its remarkable advantage is: this equipment one-time investment is little, to compare price lower with other type deduster; Equipment is directly installed on the belt conveyor head, and enclosed hood and belt are flexible coupling, and does not influence the maintenance and the replacing of belt; Also can be installed in the enclosed hood top of other process equipment, more save more compactness of space, system; Non-secondary pollution, deduster are not provided with ash bucket, the dust former material that directly falls back during deashing, and in time recovered material reaches the requirement that utilizes and economize on resources; Efficiency of dust collection is high, can reach more than 99.8%.
