The technical scheme for solving the technical problems is as follows: a hydrapulper comprises a pulping chamber, a pulp outlet chamber and a stirrer; the top and the bottom of the pulping chamber are respectively provided with a feed inlet and a slag discharge port; the pulp outlet chamber is fixed on one side of the pulp crushing chamber, the inner part of the pulp outlet chamber is communicated with the inner part of the pulp crushing chamber through a screen, and the bottom of the pulp outlet chamber is provided with a pulp outlet; the impeller of the stirrer is positioned in the pulping chamber at a position close to the screen; and a first diluting mechanism for adding water to the impeller is arranged on the pulping chamber.

The utility model has the beneficial effects that: the slurry in the pulping chamber is uniformly stirred and has uniform concentration, and the sieve mesh is not easy to block when the slurry enters the slurry outlet chamber through the screen mesh, so that the slurry outlet is smooth.

On the basis of the technical scheme, the utility model can be further improved as follows.

Further, the first dilution mechanism is a first dilution water pipe, the first dilution water pipe is fixed on the side wall of the pulping chamber, one end of the first dilution water pipe is located outside the pulping chamber and connected with an external water source, and the other end of the first dilution water pipe is located in the pulping chamber and close to the impeller.

The beneficial effect of adopting the further scheme is that: the water is added to the position close to the impeller in the pulping chamber for dilution.

Furthermore, a second diluting mechanism for adding water to the pulp outlet is arranged on the pulp outlet chamber.

The beneficial effect of adopting the further scheme is that: the slurry in the slurry outlet flows more smoothly, and the slurry pumping pump delivers smoothly.

Furthermore, the second dilutes the mechanism and is the second dilution water pipe, the second dilution water pipe is fixed go out on the lateral wall of thick liquid room, and the one end of second dilution water pipe is in go out the thick liquid outdoor connection external water source, its other end be in go out the thick liquid indoor and correspond go out the position department of thick liquid mouth top.

The beneficial effect of adopting the further scheme is that: the water is added to the position of the slurry outlet chamber, which is right opposite to the slurry outlet pipeline, for dilution.

FIG. 2 is an enlarged view A of FIG. 1;

fig. 3 is a left side view of fig. 1 with the agitator removed.

In the drawings, the components represented by the respective reference numerals are listed below:

1. the device comprises a pulping chamber, 2 a pulp outlet chamber, 3 a stirrer, 4 a feed inlet, 5 a slag discharge port, 6 a screen, 7 a pulp outlet, 8 an impeller, 9 a first dilution pipe, 10 a second dilution pipe.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

As shown in fig. 1-3, a hydropulper comprises a pulp crushing chamber 1, a pulp outlet chamber 2 and a stirrer 3. The top and the bottom of the pulping chamber 1 are respectively provided with a feed inlet 4 and a slag discharge port 5. The pulp outlet chamber 2 is fixed on one side of the pulp crushing chamber 1, the inner part of the pulp outlet chamber is communicated with the inner part of the pulp crushing chamber 1 through a screen 6, and the bottom of the pulp outlet chamber 2 is provided with a pulp outlet 7. The impeller 8 of the agitator 3 is located in the crushing chamber 1 close to the screen 6. And a first diluting mechanism for adding water to the impeller 8 is arranged on the pulping chamber 1. Preferably: the first dilution mechanism is a first dilution water pipe 9, the first dilution water pipe 9 is fixed on the side wall of the pulping chamber 1, one end of the first dilution water pipe 9 is positioned outside the pulping chamber 1 and is connected with an external water source, and the other end of the first dilution water pipe is positioned in the pulping chamber 1 and is close to the impeller 8.
