Abstract
The utility model relates to an air distributor, comprising a casing 2, a rotor shaft 4 in the casing, a rotor 3 on the rotor shaft 4 and a speed reducer 5 arranged on one end of the rotor shaft 4. Both ends of the casing are provided with an air inlet and outlet holes 6; the same cross section of the casing is provided with three air distribution openings 7 which are uniformly distributed; the air inlet and outlet holes and the air distribution openings are respectively communicated with an inner air cavity of the casing; the rotor is provided with a skew distribution separator plate 8 through which an air cavity between the rotor and the casing is divided into an air inlet cavity and an air outlet cavity; the outer circle of the rotor is provided with an air inlet 9 and a return-air opening 10, and an angle of 180 DEG is formed. The utility model has the advantages of simple and compact structure, small land occupation, convenient operation and maintenance, stable running and low noise.
Description
The utility model relates to a kind of air distributor.Be applicable to Dredge pump and dredging works supporting.Be particularly useful for environmental requirement height such as desilting before the water power dam, water factory's intake, reservoir, city river dredging, forbidden to cause the dredging works of secondary pollution in the construction, and dredging depth unrestricted (the darkest reach 200 meters under water).
Existing air distributor, complex structure adopts gear drive, and volume is big, the transmission complexity, consumable accessory is many, and noise is big.
The purpose of this utility model is to provide a kind of simple and compact for structure, operating maintenance air distributor easily.
The utility model is achieved in that a kind of air distributor, it is characterized in that it comprises: housing, place the armature spindle in the housing, be installed on rotor and the reducer that is installed on armature spindle one end on the armature spindle, the housing two ends offer port, offer three uniform air distribution openings on the same cross section of housing, port and air distribution openings all communicate with air cavity in the housing, each air distribution openings communicates with each dredge pump porting respectively, rotor is provided with oblique demarcation strip, air cavity between rotor and housing is separated into inlet chamber and discharge chamber two parts, one air inlet port and a return-air mouth are arranged on the rotor excircle, be 180 °, when epitrochanterian air inlet port is connected on the housing air distribution openings, corresponding certain cylinder barrel of air distribution openings is inflated certain cylinder barrel, press mud; When epitrochanterian return-air mouth was connected on the housing air distribution openings, corresponding certain cylinder barrel of air distribution openings carried out the air-breathing mud that advances to certain cylinder barrel.Work thus moves in circles.
Compare with existing air distributor, the utility model is simple and compact for structure, occupation of land is little, operating maintenance convenient (mounting or dismounting are convenient), and running is steady, and noise is low.

Below in conjunction with accompanying drawing the utility model is described in further detail:
Referring to Fig. 1～2, the utility model is a kind of air distributor, is applicable to Dredge pump and dredging works supporting.Be used for controlling the feeding and discharging of each mud cylinder.It mainly by housing 2, base 1, the reducer 5 that places armature spindle 4 in the housing, be installed on the rotor 3 on the armature spindle and be installed on armature spindle one end forms.
Referring to Fig. 3～5, the housing two ends offer port 6, offer three uniform air distribution openings 7 on the same cross section of housing, and port 6 and air distribution openings 7 all communicate with air cavity in the housing 2, and each air distribution openings 7 communicates with each dredge pump porting respectively.Offer gas 11 on the base 1.Pore 11 communicates with port 6.
Referring to Fig. 6～9, rotor 3 is provided with oblique demarcation strip 8, and the air cavity of 2 of rotor 3 and housings is separated into inlet chamber and discharge chamber two parts, and an air inlet port 9 and a return-air mouth 10 are arranged on rotor 3 excircles, is 180 ° of settings.Advance, return-air mouth opening is at 75～85 °.When epitrochanterian air inlet port 9 was connected on the housings air distribution openings 7, mud is inflated, pressed to corresponding certain cylinder barrel of air distribution openings to certain cylinder barrel; When epitrochanterian return-air mouth 10 was connected on the housings air distribution openings, corresponding certain cylinder barrel of air distribution openings carried out the air-breathing mud that advances to certain cylinder barrel.Work thus moves in circles.
Pressure-air is inflated each cylinder barrel respectively at regular time and quantity in turn by distributor, simultaneously to the exhaust respectively of each cylinder barrel, by correct calculating, set a rational intake and exhaust angle, make mud emptying (air inlet) in the mud cylinder, reach the mud cylinder and fill mud amount foot (exhaust), allow and advance mud in the mud cylinder of next working cycles and leave enough mud spaces of advancing.
Reducer of the present utility model adopts worm type of reduction gearing.Also can adopt planetary reducer, hydraulic motor drives, more compact structure.
