DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a configuration diagram of a non-fluid material pumping facility according to an embodiment of the present invention, and FIG.
In this non-fluid material pumping equipment, a non-fluid material pumping device 1 is provided with a fluid liquid pumping device 2.
[0010]
The non-fluid substance pressure feeding device 1 is a plan which is a pressure feeding cylinder 3, a charging chute 4 for the non-flowing substance M, and a pressure feeding member that pushes the non-flowing substance M charged in the charging chute 4 into the pressure feeding cylinder 3. A jar 6 and a pressure-feeding hydraulic cylinder 5 for reciprocating the plunger 6 back and forth are provided. A discharge valve 8 is provided at the discharge port 7 at the tip of the pressure feed cylinder 3, and a pressure feed pipe 9 for pipe pressure feed is connected to the discharge port 7 via a merging pipe 10.
[0011]
The discharge valve 8 is configured to open when the non-flowable substance M is pumped and to close when the non-flowable substance M is pushed into the pumping cylinder 1 and the plunger 4 is retracted.
A piston can also be used for the pressure feeding member.
The fluid fluid pressure feeding device 2 is a known double cylinder type piston pump, and a pair of suction / discharge ports 12A and 12B are provided on the back wall 11B of the hopper 11, and a suction / discharge port 12A, Pump cylinders 13A and 13B each having one end opened are attached to 12B. The pump cylinders 13A and 13B are respectively provided with pistons 14A and 14B, and the pistons 14A and 14B are reciprocated alternately by pump hydraulic cylinders 15A and 15B.
[0012]
A rocking tube 16 is installed in the hopper 11. The swing pipe 16 has a front end portion rotatably supported by the front wall 11F of the hopper 11, and a rear end portion alternately moves to a position facing the suction / discharge ports 12A and 12B. A discharge pipe 17 is connected to the front end of the swing pipe 16.
When the fluid fluid L is pumped by the fluid fluid pump 2, the fluid fluid L is introduced into the hopper 11. Therefore, after one piston 14A is moved backward to suck the fluid liquid L into the pump cylinder 13A, the swing pipe 16 is swung so that the rear end portion faces the suction discharge port 12A on the pump cylinder 13A side. Then, the piston 14A is advanced to discharge the fluid liquid L in the pump cylinder 13A from the swing pipe 16 to the discharge pipe 17. When one pump cylinder 13A is in the discharge stroke, the other pump cylinder 13B retracts the piston 14B and sucks the fluid fluid L into the pump cylinder 13B.
[0013]
Next, the oscillating pipe 16 is oscillated so that the rear end portion faces the suction / discharge port 12B on the other pump cylinder 13B side, the piston 14B is advanced, and the fluid L in the pump cylinder 13B is oscillated. 16 is discharged to the discharge pipe 17.
The fluid liquid L is pumped by alternately performing this suction and discharge.
The discharge pipe 17 of the fluid fluid pressure feeder 2 is connected to and communicates with the merge pipe 10. Accordingly, the fluid liquid L discharged from the fluid fluid pressure feeding device 2 joins the non-fluid material M ejected from the non-fluid material pressure feeding device 1.
[0014]
The pumping of the non-fluid substance M by the non-fluid substance pumping equipment is performed in the process shown in FIG.
First, in step 1, the non-fluid substance M is thrown into the charging chute 4 of the non-fluid substance feeding device 1. At this time, in the non-flowable substance pressure feeding device 1, the discharge valve 8 is closed, and the plunger 6 is in the retracted state. On the other hand, in the fluid fluid pressure feeding device 2, the fluid fluid L is pumped by the forward movement of the piston 14A, and the fluid fluid L is sucked into the pump cylinder 13B by the backward movement of the piston 14B.
[0015]
In the stroke 2, the non-flowable substance M charged into the charging chute 4 is pushed into the pressure feeding cylinder 3 by the plunger 6. At this time, in the fluid liquid pressure feeding device 2, the swing pipe 16 moves from the suction / discharge port 12A to a position facing the suction / discharge port 12B.
In stroke 3, the discharge valve 8 is opened, and in stroke 4, the plunger 6 advances in the pressure feed cylinder 3, and the non-fluid substance M is pressure-fed from the discharge port 7.
[0016]
In stroke 5, the discharge valve 8 is closed, and in stroke 6, the piston 14B of the fluid fluid pressure feeding device 2 moves forward to pump fluid fluid L, and the piston 14A moves backward to suck fluid fluid L. Do. The fluid liquid L discharged from the discharge pipe 17 enters the junction pipe 10 and joins with the non-flowable substance M previously discharged from the non-flowable substance pumping apparatus 1, and further moves the non-flowable substance M forward. To the pressure.
[0017]
In step 7, the plunger 6 of the non-fluid substance pressure feeding device 1 moves backward, and at the same time, the swing pipe 16 of the fluid liquid pressure feeding device 2 moves from the suction discharge port 12B to the position facing the suction discharge port 12A.
Thereafter, the process returns to step 1, and in the fluid fluid pressure feeding device 2, the piston 14 </ b> A moves forward to feed the fluid fluid L under pressure.
[0018]
Thus, the discharge of the non-fluid substance M by the non-fluid substance pumping apparatus 1 and the discharge of the fluid liquid L by the fluid liquid pumping apparatus 2 are alternately repeated. Since the fluid fluid L ejected from the fluid fluid pressure feeder 2 joins the fluid fluid M ejected from 1, the fluid fluid M is compared with the case where only the fluid fluid M is pumped. Thus, the flow in the pressure feeding pipe 9 is improved and the blockage is prevented, and the non-flowable substance M can be smoothly fed by pressure in a stable state.
[0019]
This non-fluid material pumping equipment 2 is used, for example, in a sewage treatment plant where non-fluid material residue and dehydrated cake, which is a fluid liquid, are combined and fed to an incineration facility for incineration. In this case, it is preferable to use the crushed waste, which is a non-fluid substance, and the dehydrated cake, which is a fluid liquid, when they are combined and fed to a melting furnace for melting treatment.
[0020]
【The invention's effect】
