Preferably, the casing afterbody is equipped with the water inlet, the casing lowermost end sets up the outlet pipe, the motor shaft stretches out the casing with impeller shaft fixed connection specifically does the motor shaft passes the water inlet pass through the shaft coupling with impeller shaft fixed connection.

Preferably, a machine head protection cover used for protecting the cable and changing the motion track is fixed on the head of the shell, and the machine head protection cover is arc-shaped.

Preferably, an impeller protective cover used for preventing the pump impeller from colliding with the inner wall of the methane tank is covered outside the stirring impeller, and the pump impeller protective cover is fixedly connected with the shell.

Preferably, an anchor hook for lifting is fixed at the top of the shell.

Preferably, the water outlet pipe is an L-shaped pipe, and a water outlet of the water outlet pipe faces the direction of the stirring impeller.

Preferably, the coupling is a claw coupling.

Therefore, the submersible sludge stirrer adopting the structure can move at the bottom of the methane tank through the stirring impeller pushing device without traction control by combining the submersible sewage pump and the stirring impeller, and can simultaneously break the deposited shell at the bottom of the methane tank, so that the fermentation is more thorough.

The technical solution of the present invention is further described in detail by the accompanying drawings and embodiments.

Detailed Description

The present invention will be further described with reference to the accompanying drawings, and it should be noted that the present embodiment is based on the technical solution, and the detailed implementation and the specific operation process are provided, but the protection scope of the present invention is not limited to the present embodiment.

FIG. 1 is a cross-sectional view of a submersible sludge agitator according to an embodiment of the present invention, which comprises a submersible sewage pump at the head and a stirring impeller 4 at the tail, wherein the submersible sewage pump is arranged at the head of the apparatus, the stirring impeller 4 is arranged at the tail of the apparatus, the agitator can be pushed to move while being stirred by the stirring impeller 4, so as to achieve the purpose of pushing the agitator to move without traction and an additional controller, wherein the submersible sewage pump comprises a housing 1, a motor 2 and a pump body impeller 3 which are arranged in the housing 1, the head of the housing 1 is fixed with a head protective cover 10 for protecting a cable and changing a motion track, and the head protective cover 10 is arc-shaped, so that when a head of the agitator touches the inner wall of a biogas digester, the head can gradually change direction under the pushing of the stirring impeller until the head is separated from the contact with the inner wall of the biogas digester, the problem that a conventional submersible pump cannot turn when touching the inner wall of the head of the biogas digester is solved, the tail of the housing 1 is provided with a water inlet 6, the lowest end of the housing 1 is provided with a water outlet pipe 5, the water outlet pipe 5 is an L-shaped pipe, the impeller 4 is an impeller shaft, the impeller shaft is fixed with a shaft, and a shaft coupler 20, the impeller shaft of the impeller is connected with a motor shaft, the impeller 1 is more reliable connection with a water shaft, and a water outlet shaft, and a water shaft, the impeller 20 is connected with the impeller, and the impeller shaft of the impeller, and the impeller shaft is fixed on the impeller, and the impeller 1, the impeller protective cover 7 for preventing the pump impeller 3 from colliding with the inner wall of the methane tank is covered outside the stirring impeller 4, and the impeller protective cover 7 is fixedly connected with the shell 1, so that the structure is more stable. The 1 top of casing is fixed with fluke 8 that is used for going up and down, through on being fixed the fluke 8 with the hoist and mount rigging, can transfer the agitator through between the ejection of compact by the methane-generating pit, until putting into the bottom of the pool with the agitator, put forward the agitator by between the ejection of compact again after the work finishes, accomplish the lift work of agitator, and can be fixed the cable and hoist and mount rigging on same controlling means when using for the cable moves about together with the hoist and mount rigging.

According to the structure of the submersible sludge stirrer, the working process is as follows:

when the device is used, firstly, an operator can lift the end fixing belt anchor hooks 8 of the hoisting rope tool, the stirrer is placed to the bottom of the tank between the feeding of the methane tank, the power switch is turned on, the motor 2 drives the pump body impeller 3 and the stirring impeller 4 to rotate simultaneously, the stirring impeller 4 can generate force for pushing the stirrer to move forward when rotating the sedimentation at the bottom of the stirring tank, so that the stirrer moves forward, meanwhile, water at the bottom of the tank enters from the water inlet 6 at the head of the stirrer, water is discharged to the water outlet at the lowest end of the shell 1 due to the centrifugal force of the pump body impeller 3, and due to the principle of acting force and reaction force, force for pushing the stirrer to move forward can be generated, until the stirring work is completed, the power supply is turned off, and the stirrer is lifted out from the discharging room to complete the whole work.

Finally, it should be noted that: the above embodiments are only intended to illustrate the technical solution of the present invention and not to limit the same, and although the present invention is described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: modifications and equivalents may be made to the invention without departing from the spirit and scope of the invention.
