Abstract
The invention relates to an air distributor which is suitable for being matched with a dredging pump and dredging engineering and is used for controlling the charging and discharging of each mud cylinder. The air distributor comprises a shell (1), a main shaft (6), a rotor (4) and a speed reducer, wherein the speed reducer is arranged at one end of the main shaft (6) and is arranged on one side of the shell (1), an end cover (7) is fixedly arranged on the other side of the shell (1), a connection pipe (9) is fixed on the outer side of the end cover (7) and comprises three evenly-distributed air distribution pipes, an air inlet port (101) and an air outlet port (102) are arranged on the shell (1), an air inlet (401) and a return air hole (402) are arranged on the rotor (4), a static valve plate (10) is fixed on the inner side of the end cover (7), a movable valve plate (11) is fixed on one side of the rotor (4) near the end cover (7), and the movable valve plate (11) and the static valve plate (10) are matched in contact. In the invention, the rotor and the shell do not need to be integrally replaced, therefore, the service life of the complete air distributor can be greatly prolonged.
Description
(1) technical field
The present invention relates to a kind of air distributor.Be applicable to dredging works in used mud jar Dredge pump (claiming air-powered pump again) supporting.It is used for controlling the feeding and discharging of each mud jar.Be particularly useful for being forbidden to cause in environmental requirement height, the constructions such as the clear stasis of blood, water factory's intake, reservoir, city river dredging before the hydroelectric dam dredging works of secondary pollution, and dredging depth unrestricted (the darkest reach 200 meters under water).
(2) background technique
Existing air distributor, mainly by housing, the retarder that places main shaft in the housing, be installed on the rotor on the main shaft and be installed on main shaft one end forms.Abominable by the what applying working condition, rotor and housing are are very easily worn and torn, then need integral replacing rotor and housing, so the working life of air distributor is shorter.
(3) summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of air distributor that can increase the service life is provided.
The object of the present invention is achieved like this: a kind of air distributor, comprise housing, place the main shaft in the housing, the retarder that is installed on the rotor on the main shaft and is installed on main shaft one end, described retarder is installed on housing one side, opposite side at housing is installed with an end cap, this end cap outside is fixed with connecting tube, described connecting tube comprises three uniform air distributions, described housing is provided with an inlet hole and an exhaust port, described rotor is provided with a suction port and a return-air mouth, inlet hole on this suction port and the housing and the air distribution in the described connecting tube match, air cavity is connected in air distribution in return-air mouth and the connecting tube and the housing, and air cavity is connected with exhaust port on the housing in the housing; Be fixed with a quiet valve plate in described end cap inboard, be fixed with a moving valve plate, the cooperation that contacts with described quiet valve plate of this moving valve plate in a side of the close end cap of described rotor.
The present invention is the column type distribution device of being made up of rotor and shell existing, has made the plane type distribution device of being made up of moving valve plate and quiet valve plate into.
The invention has the beneficial effects as follows:
1, easy to manufacture.
2, maintenance is easy, and the wearing and tearing simple and easy maintenance in back can continue to use.
3, need change the assembly of different valve timing diagrams according to the depth of water and operating mode, the design of these assemblies, manufacturing and replacing all are easier to.
4, the present invention can be fixed on the mud jar and dive into the water together, shortens breather line length greatly, and (especially in deep water), thus significantly reduce compressed-air actuated consumption, saved the energy.

(5) embodiment
Referring to Fig. 1~5, Fig. 1 is the perspective view of air distributor of the present invention.Fig. 2 is the right perspective view of Fig. 1.Fig. 3 is the Facad structure exploded view of Fig. 1.Fig. 4 is the structural representation of air distributor of the present invention.Fig. 5 is the left side view of Fig. 4.By Fig. 1~Fig. 5 as can be seen, air distributor of the present invention comprises housing 1, places the main shaft 6 in the housing 1, the worm type of reduction gearing that is installed on the rotor 4 on the main shaft 6 and is installed on main shaft 6 one ends, and this worm type of reduction gearing is installed on housing 1 one sides.The opposite side of housing 1 is installed with end cap 7 with hex head screw 5, and end cap 7 outsides are fixed with connecting tube 9.Connecting tube 9 comprises three uniform air distributions, and each air distribution communicates with the porting of each dredge pump respectively.Inlet hole 101 and exhaust port 102 are set on the housing 1, rotor 4 is provided with a suction port 401 and a return-air mouth 402, inlet hole 101 on suction port 401 and the housing 1 and the air distribution in the connecting tube 9 match, air cavity is connected in air distribution in return-air mouth 402 and the connecting tube 9 and the housing 1, and air cavity is connected with exhaust port 102 on the housing 1 in the housing 1.
Referring to Fig. 4, Fig. 4 is the structural representation of air distributor of the present invention.As seen from Figure 4, air distributor of the present invention is fixed with a quiet valve plate 10 in described end cap 7 inboards, is fixed with a moving valve plate 11 in a side of the close end cap 7 of described rotor 4, the cooperation that contacts with described quiet valve plate 10 of this moving valve plate 11.
Working principle:
When the air distribution in the epitrochanterian suction port 401 connection connecting tubes 9, mud is inflated, pressed to corresponding certain cylinder barrel of air distribution mouth to certain cylinder barrel; When air distribution that epitrochanterian return-air mouth 402 is connected in the connecting tubes 9, corresponding certain cylinder barrel of air distribution mouth carries out the air-breathing mud that advances to certain cylinder barrel.Work thus moves in circles.
High-pressure air is inflated each cylinder barrel respectively at regular time and quantity in turn by air distributor, simultaneously to the exhaust respectively of each cylinder barrel.
Worm type of reduction gearing of the present invention is driven by oil hydraulic motor, more compact structure.
