Technical Field

The invention relates to the technical field of submersible pumps, in particular to an air injection type submersible pump.

Background

Traditional immersible pump draws water in capital construction tunnels such as building, bridge, mine, and the drainage has easy burning motor during the construction, and the security is poor, and the maintenance is complicated. In complex environments such as mines and the like, muddy water is easy to block a motor rotor by an electric submersible pump, the cost of the sewage submersible pump is high, the drainage environment after urban storm water is complex, the electric safety is high due to overlong cable laying, the traditional air pump is low in efficiency and slow in drainage speed, and the like.

Disclosure of Invention

The invention aims to solve the technical problem of overcoming the technical defects and provides an air injection type submersible pump.

In order to solve the problems, the technical scheme of the invention is as follows: an air injection type submersible pump comprises a shell, an air valve cylinder body, a piston, a connecting rod, a magnetic colloid one-way valve, a water filtering screen, a water inlet one-way valve, a water outlet pipe and a water outlet one-way valve, wherein an air compression chamber is arranged at the top of the shell, an air inlet is arranged at the top of the shell, the bottom of the air inlet is connected with the air valve cylinder body, the piston is arranged in the air valve cylinder body, the bottom of the piston is connected with the connecting rod, the air valve cylinder body is arranged at the bottom end of the connecting rod in a penetrating mode and is connected with the magnetic colloid one-way valve, the magnetic colloid one-way valve extends into a cavity at the lower part of the shell, the bottom of the shell is provided with the water filtering screen, a first maintenance sealing interface and a second maintenance sealing interface are respectively arranged at the upper end and the lower end of the cavity at the lower part of the shell, the water inlet one-way valve is arranged between the cavity at the lower part of the shell and the water filtering screen, the water outlet pipe is inserted into the cavity at the inner part of the air compression chamber, the bottom of the water outlet pipe extends into the cavity at the lower part of the shell, and the top end of the water outlet pipe is provided with a water outlet one-way valve.

As an improvement, the connecting rod is of an L-shaped structure, and the magnetic colloid one-way valve obliquely penetrates into the cavity at the lower part of the shell.

As an improvement, the bottom of the water filtering net cover is of an arc-shaped structure.

Compared with the prior art, the invention has the advantages that: the invention takes the structure of the compression injection type gas chamber as a main body, has simple structure and high energy efficiency ratio, does not have the phenomenon of low efficiency caused by intermittent gas supply of a traditional air pump, and utilizes aerodynamic energy to the maximum extent. The water inlet and outlet valve is specially designed and matched with an air compressor for use, and can pump water in capital construction, mine pits and tunnels, and mine tunnels filled with flammable and explosive gases have high drainage safety, and cables are not laid in complex environments such as urban storm flood drainage, so that the safety type is high, the structure is reasonable, simple and not easy to damage, and the like.
