Abstract
The utility model discloses a jet pump, comprising a jet pump body. The upper end of the jet pump body is connected with the ash bucket of a dust remover. The middle part of the jet pump body is provided with a material discharge and material distributing device, and the lower end of the jet pump body is provided with a venturi pipe of the front half part. The center of the open end of the diverging tube of the venturi pipe of the front half part is provided with a nozzle. The connecting pipe of the nozzle of the outside of the lower end of the jet pump body is provided with a blowing assembly and an electromagnetic valve. The outside of the lower end of the jet pump body is provided with a venturi tube of the rear half part which is connected with the venturi pipe of the front half part. The utility model has the advantages of reasonable and compact structure, little space occupation, low cost, no requirement on the air quality, stable operation, and convenient installation and overhauling.
Description
The utility model relates to the jet-type Pneumatic conveyer, relates in particular to jet pump.
At present domestic in the malleation dilute phase of using, there are some defectives in malleation concentrated phase Pneumatic conveyer (storehouse pump) and vacuum pressure conveying pneumatic transport equipment.As the malleation dilute phase, air consumption is big, makings require high, want oil removing, dewater, drying.Gasification board is perishable during operation, needed to change in general about 20 days, and easily plugging.Malleation concentrated phase, makings require higher, oil removing, dewater, drying, intermitten operation, easily plugging, and pipeization plate needs replacing about 20 days, and discharge valve is easy to wear, and general 40～60 days need replacing.The vacuum pressure conveying fed distance is short, cloth bag is easily stifled, operating cost is high.
The purpose of this utility model provides a kind of compactness rational in infrastructure, installs and overhauls jet pump easily.
The utility model is taked following measures in order to achieve the above object: jet pump has injection pump housing, the injection pump housing upper end joins with dust collector ash hopper, the middle part is provided with the discharging broadcast feeder, the lower end is provided with the front half part Venturi tube, be provided with nozzle at front half part Venturi tube expanding duct opening end center, in the outside, injection pump housing lower end, nozzle is taken over to be provided with and is blown down assembly and solenoid valve, be provided with the latter half part Venturi tube in the outside, injection pump housing lower end, and link to each other with the front half part Venturi tube.
Advantage of the present utility model: 1. rational in infrastructure, compact, take up room little, cost is low.2. air quality there is not specific (special) requirements.3. the method for operation is continuously steady formula.4. install, overhaul conveniently.5. operation continuously steadily can plugging.6. few replacement cycle of rapid wear is more than 1 year.7. consume that gas is fixed with quantity delivered, air pressure with fed distance fixed, random good, save power.8. main frame is that the jet pump supplementary equipment is few in the system, and total investment expenses are economized.
Elaborate below in conjunction with accompanying drawing:
Accompanying drawing is the jet pump structure schematic representation.
Jet pump has injection pump housing, the injection pump housing upper end joins with dust collector ash hopper 1, the middle part is provided with discharging broadcast feeder 2, the lower end is provided with front half part Venturi tube 3, be provided with nozzle 5 at front half part Venturi tube expanding duct opening end center, in the outside, injection pump housing lower end, nozzle is taken over to be provided with and is blown down assembly 6 and solenoid valve 7, be provided with latter half part Venturi tube 4 in the outside, injection pump housing lower end, and link to each other with the front half part Venturi tube.Nozzle is provided with the flexible adjusting device of nozzle.Front half part Venturi tube and latter half part Venturi tube joint are provided with the flexible adjusting device of Venturi tube.Blow down assembly and have collection chamber, collection chamber is taken over nozzle and is linked to each other, and collection chamber is connected to many blow off pipes and links to each other with the injection pump housing inner chamber respectively, and blow off pipe is provided with ball valve.Injection pump housing and the integral cast of front half part Venturi tube.
The utility model working principle: open earlier electromagnetic valve, high-pressure air by electromagnetic valve, injection caburation assembly, non-return cut down, nozzle, with high speed (supersonic speed) high pressure draught directive Venturi tube, make to form negative pressuren zone in the pump chamber, pulverized fuel ash (powdered granule) is pressed predetermined ash discharge amount (20M by discharge apparatus
3/ h～50M
3/ h) fall into pump chamber equably, sucked Venturi tube by high-voltage high-speed airflow from the nozzle ejection, enter ash-conveying tube after the mixing homogenizing and import grey storehouse.Ash in storehouse or ash bucket is totally lost, and the discharging broadcast feeder can close, blow down cleaning and close electromagnetic valve again after one minute, and a working procedure finishes, and next working procedure repeats work by above program.The whole service process is controlled automatically by a programming controller.The defeated ash amount and the fed distance of jet pump are determined by air quantity and air pressure head.After providing the defeated ash amount and fed distance that needs as the Party A, the Party B just can be by selected gas gray scale size definite injection pump size and air quantity, air pressure head.
