Part of horizontal is set in the horizontal pipe 7, several blades 42 be set in the horizontal pipe 7 and it is circumferentially distributed in
The shaft 41 is located at the outer surface of the part in the horizontal pipe 7；The side of every blade 42 is connected to the shaft 41,
The inner wall direction of another lateral horizontal pipe 7 extends and contacts therewith；The power mechanism is connected to the shaft 41 and is used in combination
It is rotated in the driving shaft 41；The top and bottom of the horizontal pipe 7 are respectively equipped with the inlet and outlet communicated with outside
10。
The working principle of the above-mentioned underflow discharge device for the dense hopper of ore pulp is:
The import at 7 top of horizontal pipe is connected to the gape of dense 100 bottom of hopper of ore pulp first, as shown in Figure 4.
After entering the dense hopper 100 of ore pulp to mine, underflow sinks to the gape of dense 100 bottom of hopper of ore pulp, pushes up from horizontal pipe 7
The import in portion flows into the horizontal pipe 7, is gathered in the top of blade discharging mechanism 4.This is because each blade 42 is another
Side is in contact to form sealing with the inner wall of horizontal pipe 7, if shaft 41 does not rotate, interception of the underflow in each blade 42
It can only be gathered in the top of blade discharging mechanism 4 down, be unable to flow down.
When needing to realize underflow discharge, the shaft 41 is driven to rotate by power mechanism, blade 42 is with described turn
Axis shaft together, then be gathered in underflow between each blade 42 turn to it is corresponding with the outlet 10 of 7 bottom of horizontal pipe
10 discharge of outlet can be passed through when position.After the completion of high-concentration underflow discharge, stop power mechanism, shaft stops operating, underflow
It is pinned immediately.
Further, the both ends of the blade 42 are in contact with the both ends in the horizontal pipe 7 respectively.Make blade 42
Both ends are also in contact with the both ends inside horizontal pipe 7, and (length that can be the two is set as consistent or blade using flexible
The length of blade can be made to be greater than the length inside the horizontal pipe when material), it may further ensure that and discharge machine in blade
When structure does not rotate, the space above and below blade discharging mechanism is obstructed completely.
Further, the distance between each blade 42 is equal.
In the present embodiment, the quantity of blade is 3.In a particular application, can also be arranged according to actual needs more
Blade quantity.
Further, the blade can use flexible material, and blade discharging mechanism entirety and the horizontal pipe
Inside interference fit.Blade is made using flexible material, and makes interference inside the whole and described horizontal pipe of blade discharging mechanism
Cooperation (i.e. the outer diameter of blade discharging mechanism entirety is greater than the internal diameter inside blade discharge tube), can play better seal effect
Fruit, the more preferable forced discharge for realizing underflow.
In the present embodiment, one end of the shaft 41 is pierced by one end of the horizontal pipe 7 and 5 gap of axle sleeve of one end
Cooperation, and connect with the power mechanism.Further, in the present embodiment, the other end of the shaft 41 is pierced by described
The other end of horizontal pipe 7, and the axle sleeve clearance fit with the other end.The both ends of the horizontal pipe 7 by end cap flange 6 with
Axle sleeve 5 connects.
Further, in the present embodiment, the power mechanism is motor driver.The motor driver includes
Motor 1 and retarder 2, the output shaft of the motor 1 are connected to one end of the shaft 41 by retarder 2.In the present embodiment
