Abstract

The utility model relates to an air distributor suitable for matching a dredge pump and dredging work and used for controlling the feed and discharge of each mud cylinder. The air distributor comprises a shell (1), a main shaft (6), a rotor (4) and a reducer arranged at one end of the main shaft (6), wherein the reducer is arranged on one side of the shell (1); the other side of the shell (1) is provided with an end cover (7); a connecting pipe (9) is fixed on the outer side of the end cover (7), and comprises three uniformly distributed air distributing pipes; the shell (1) is provided with an air inlet (101) and an air outlet (102); the rotor (4) is provided with an air inlet (401) and an air outlet (402); a static valve plate (10) is fixed on the inner side of the end cover (7); a moving valve plate (11) is fixed on one side of the rotor (4) close to the end cover (7); and the moving valve plate (11) is in contact fit with the static valve plate (10). The rotor and the shell are not needed to be replaced integrally, so the service life of the whole machine can be greatly prolonged.

Description

Air distributor

(1) technical field

The utility model 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 such as desilting before the hydroelectric dam, water factory's intake, reservoir, city river dredging, the construction 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.Because applying working condition is abominable, and rotor and housing are are very easily worn and torn, and then need integral replacing rotor and housing, so the working life of air distributor is shorter.

(3) summary of the invention

The purpose of this utility model is to overcome above-mentioned deficiency, and a kind of air distributor that can increase the service life is provided.

The purpose of this utility model is achieved in that 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 utility model 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 beneficial effects of the utility model are:

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 utility model 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 the utility model air distributor.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 the utility model air distributor.Fig. 5 is the left side view of Fig. 4.By Fig. 1～Fig. 5 as can be seen, the utility model air distributor, comprise housing 1, place 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, 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 the utility model air distributor.As seen from Figure 4, the utility model air distributor 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 utility model is driven by oil hydraulic motor, more compact structure.
