Abstract
The invention relates to a dredging pneumatic pump, which is used for clearing sludge. The dredging pneumatic pump comprises a pump body (5), wherein a sludge discharging joint (6) is fixedly inserted into the head part of the pump body (5); a cylinder (4) is fixedly arranged on the rear part of the pump body (5); the tail part of the pump body (5) is inserted into the cylinder (4); a sludge sucking body (1) is fixedly connected to the inner ring of the cylinder (4); the head part of the sludge sucking body (1) is inserted into the cylinder (4); an O-shaped seal ring (2) is embedded between the outer edge of the sludge sucking body (1) and the inner ring of the rear part of the cylinder (4); an air suction device (3) is arranged on the outer edge of the cylinder (4); and an annular compressed air passage (7) is formed between the outer edge of the head part of the sludge sucking body (1) and the inner ring of the tail part of the pump body (5). The dredging pneumatic pump has the advantages that: the dredging pneumatic pump does not need to be placed in a working environment which needs to be dredged, is convenient to operate and based on a simple working principle, avoids structural failures and has high reliability.
Description
Technical field
The present invention relates to a kind of pneumatic pump, be specifically related to a kind of desilting pneumatic pump.Be used for the removing of mud etc.Belong to pipeline valve member technical field.
Background technique
Removing sludge generally all adopted pump type under the complete machine dry type in the past, and motor adopts grease chamber's sealing means, in establish mechanical seal, main impeller and agitator arm also are housed, complex structure.In case bad seals or aging is prone to fault, simultaneously, when complex environment or the cleaning work of light section working environment, be subjected to very big a restriction of removing sludge boundary dimension and an operational difficult problem.
Summary of the invention
The objective of the invention is to overcome above-mentioned deficiency, a kind of desilting pneumatic pump that is applicable to work under the various desilting working environments is provided, and desilting pneumatic pump simple in structure, easy to operate.
The object of the present invention is achieved like this: a kind of desilting pneumatic pump, comprise the pump housing, fixedly be plugged with a mud at pump housing head and discharge joint, be installed with a cylindrical shell at described pump housing rear portion, and pump housing afterbody is inserted in this cylindrical shell, described cylindrical shell inner ring is fixedly connected with a mud suction body, and mud suction body head is inserted in the described cylindrical shell, and between mud suction body outer rim and cylindrical shell rear portion inner ring, set an O RunddichtringO, with be provided with an air suction device in the cylindrical shell outer rim, and make between mud suction body external edge of head and the pump housing afterbody inner ring and to keep an annular compression air passageways.
The invention has the beneficial effects as follows:
Desilting air-flow of the present invention is placed in the outside that is subjected to the desilting environment, need not put into the working environment of required desilting, only needs corresponding flexible pipe is fed the place that needs desilting, inserts the pressurized air of certain pressure, just can normally carry out desilting work.Therefore be applicable to various desilting working environments, and simple in structure, easy to operate.Working principle is simple, and structure is difficult for breaking down good reliability.
Description of drawings
Fig. 1 is the structural representation of desilting pneumatic pump of the present invention.
Reference character among the figure:
Mud suction body 1, O RunddichtringO 2, air suction device 3, cylindrical shell 4, the pump housing 5, mud are discharged joint 6, annular compression air passageways 7.
Embodiment
Referring to Fig. 1, Fig. 1 is the structural representation of desilting pneumatic pump of the present invention.As seen from Figure 1, desilting pneumatic pump of the present invention, comprise the pump housing 5, fixedly be plugged with a mud at the pump housing 5 heads and discharge joint 6, the pump housing 5 rear portions are installed with a cylindrical shell 4, and the pump housing 5 afterbodys are inserted in this cylindrical shell 4, described cylindrical shell 4 inner rings are fixedly connected with a mud suction body 1, and mud suction body 1 head is inserted in the described cylindrical shell 4, and between mud suction body 1 outer rim and cylindrical shell 4 rear portion inner rings, set an O RunddichtringO 2, it is fully sealed and be provided with an air suction device 3 in cylindrical shell 4 outer rims, it mainly acts on is to link to each other with pressurized air.And make reservation one annular compression air passageways 7 between mud suction body 1 external edge of head and the pump housing 5 afterbody inner rings, and has certain directivity.
When air suction device 3 links to each other with pressurized air, the pressurized air that has a certain pressure enters in the annular compression air passageways 7 between the mud suction body 1 and the pump housing 5, and flows to the outlet port, at this moment, take away the mud suction body simultaneously with the air in the passage, make it produce negative pressure.When mud suction body rear end connects the desilting pipeline, at this moment, mud flows to mud with pressurized air and discharges joint along with negative pressure enters in the mud suction body passage.Along with pressurized air is mobile endlessly, mud is discharged joint by mud go out clearly.
Claims (1)
1. desilting pneumatic pump, comprise the pump housing (5), it is characterized in that: fixedly be plugged with a mud at the pump housing (5) head and discharge joint (6), be installed with a cylindrical shell (4) at the described pump housing (5) rear portion, and the pump housing (5) afterbody is inserted in this cylindrical shell (4), described cylindrical shell (4) inner ring is fixedly connected with a mud suction body (1), and mud suction body (1) head is inserted in the described cylindrical shell (4), and between mud suction body (1) outer rim and cylindrical shell (4) rear portion inner ring, set an O RunddichtringO (2), with be provided with an air suction device (3) in cylindrical shell (4) outer rim, and make between mud suction body (1) external edge of head and the pump housing (5) the afterbody inner ring and to keep an annular compression air passageways (7).
