Description

DETAILED DESCRIPTION OF THE INVENTION Industrial Field of the Invention The present invention relates to an underwater agitation pump that can be used for both agitation, water absorption, and pumping.

2. Description of the Related Art Conventionally, in a submersible pump, a motor drive unit is hermetically sealed in a cylindrical casing, an impeller is attached to a rotary shaft of the motor drive unit, and water sucked from an intake port facing the impeller is cylindrical casing. It is designed to send water to a pump hose connected to the upper end of the.

Therefore, the submersible pump is pumping water while directly inhaling the water while the pump main body is in contact with the water in the tank or the reservoir. However, in order to mud-dye rush seedlings, in the mud-dying agitation tank, the soil is agitated and other water is absorbed
It was inconvenient because there was no submersible pump that also used to pump the agitated mud dyeing liquid, and a special stirring pump was used.

In order to eliminate such problems, the present invention stirs,
A submersible pump capable of both absorbing and pumping water, which is characterized in that the convenience in a stirring tank can be improved.

Means for Solving Problems The constitution of the present invention will be described below with reference to the drawings.

An annular partition plate 2 is provided at an intermediate height position on the inner peripheral surface of the cylindrical casing 1 to divide the inside into an upper discharge chamber 3 and a lower suction chamber 4, and a bottom plate 5 of the cylindrical casing 1 is provided with a suction port 6.
Is opened, and the left and right discharge pipes 7, 7 ′ are laterally communicated and projected at the front side of the left side face and the rear side of the right side face of the discharge chamber 3 of the cylindrical casing 1, and inside the outer end parts of the left and right discharge pipes 7, 7 ′. The water amount adjusting bush 8 is detachably locked with a screw, the pumping pipe 9 is connected to the front of the discharge chamber 3 and the water suction pipe 10 is connected to the front of the suction chamber 4, and the water suction pipe 10 is connected to the suction port of the bottom plate 5. 6, the supporting leg 11 is fixed to the lower surface of the bottom plate 5, and the cylindrical casing 1
Of the motor 1.3 of the cylindrical casing 1 by fitting the impeller 15 to the discharge shaft 3 of the cylindrical casing 1 by fixing the impeller 15 to the rotating shaft 14 protruding from the lower surface of the hermetically sealed motor 13. The lower end flange 16 is fixed to the upper end flange 12 of the cylindrical casing 1 with a bolt nut 17 to form an underwater stirring pump 18. In the figure, 19 is a pumping hose, 20 is a water absorption hose, 21 is a stirring tank, 22 is a water tank, 23 is a mud dyeing machine, and 24 is a power cord.

The submersible agitation pump 18 according to the present invention has a pumping hose 19 connected to the pumping pipe 9 of the cylindrical casing 1 and a water absorption hose 20 connected to the water absorption pipe 10, respectively. The water suction hose 20 is connected to the external water tank 22, the pump hose 19 is connected to the mud dyeing machine 23, and the submersible agitation pump 18 is activated. Rotation axis of motor 13
When the impeller 15 rotates at high speed in the discharge chamber 3 together with 14, the suction negative pressure acts on the suction chamber 4 to suck the outside water from the suction port 6 of the bottom plate 5, and the water sucked into the discharge chamber 3 While being accelerated and discharged from the left and right discharge pipes 7 and 7'at high speed, the water in the stirring tank 21 circulates in the cylindrical casing 1 and stirs the dyed soil and water put into the stirring tank 21. At the same time, the dyed soil solution that is stirred at the same time is pressure-fed to the mud-dyeing machine 23 through the pump hose 19 that communicates with the discharge chamber 3, and the water in the water tank 22 passes through the water-absorption hose 20 and inside the stirring tank 21. Will be sequentially replenished.

Therefore, in the submersible agitation pump 18 of the present invention, by agitating the water in the agitation tank, the water in the agitation tank is agitated, the water in the external water is absorbed into the tank, and the agitating liquid in the tank is externalized. Pumping to 1
It can be used as a stand, and it can be used efficiently without the need for an auxiliary pump, by just putting it in the water of the stirring tank of the rush mud dyeing liquid, etc. It has various remarkable effects.
