Description
The utility model relates to a kind of dewater unit of Separation of Solid and Liquid.
The used drainage bin of stone coal in existing lime-ash drainage bin that is used for big-and-middle-sized thermal power plant hydraulic slag discharging system and the coal pulverizer discharge system, all has the dehydration warehouse, the discharge port of feed pipe and drainage bin bottom, the inwall of dehydration warehouse is provided with the bleed element, water in the mixture of material is separated out from the bleed element of drainage bin, but because mixture adopts the precipitation method to dewater in drainage bin, promptly rely on the gravity of water, the adhesive force that overcomes the surface of solids dehydration of flowing automatically, the material dewatering time is longer, and dehydration back body surface water content also can reach 20%, material dewatering is unclean, so general thermal power plant need dispose more drainage bin, could satisfy the needs of production cycle.
It is fast that the purpose of this utility model provides a kind of material dewatering speed, material dewatering rate height, the fast dewatering device that utilization rate of equipment and installations is high.
The technical solution of the utility model is: a kind of drainage bin fast dewatering device, drainage bin top is provided with feed pipe, the bottom is provided with ash gate and discharging opening, the drainage bin inwall is provided with bleed element and gravity flow cross current, it is characterized in that, the pump mouth of jetting aspirator is communicated with the bleed element by the bleed pipe, and the delivery port of jetting aspirator is communicated with drainpipe; The water inlet of jetting aspirator links to each other with water pump by penstocks, and water pump is communicated with water inlet pipe.
For the water that makes full use of discharge carries out recyclingly, improvement of the present utility model is that also drainpipe is communicated with water tank, and the water inlet pipe that is communicated with water pump also is communicated with water tank.
In order to prevent the obstruction of bleed element and bleed pipe, can adopt following structure, be that the bleed pipe is provided with the bleed valve, on the bleed pipeline section between bleed valve and the import of bleed pipe, be communicated with recoil tube, penstocks are provided with water intaking valve, are being communicated with recoil tube on the press water pipeline section between water intaking valve and the water pump, and recoil tube is provided with recoil valve.
The beneficial effects of the utility model are: because of installed bleed pipe and jetting aspirator thereof additional on drainage bin, so the water of separating out through the bleed element in the warehouse is again when the bleed pipe flows into the jetting aspirator, under the formed powerful negative pressure of vacuum attraction force acts of pressure fluid in the jetting aspirator, accelerated the bleed speed of bleed element, thereby accelerated the dehydration of mixture surface water, make the dewatering speed of object in the drainage bin bring up to 50%, and dehydration back body surface water content is about 10%, especially to using under coal ash part content condition with higher, drainage bin can satisfy the needs of production cycle, can save the investment of equipment.
Below in conjunction with accompanying drawing the novel embodiment of this reality is further described.
Fig. 1 is an example structure schematic diagram of the present utility model.
Fig. 2 is the drainage bin schematic diagram of band feed pipe.
As Fig. 1, shown in 2, drainage bin (3) top is provided with feed pipe (1), feed pipe (1) is installed on the distributing trough (21), also being provided with downflow weir (22) on the drainage bin (3) is communicated with overflow pipe (2), and vibrator (23) also is equipped with to prevent warehouse inwall adhered materials in the middle part of drainage bin (3), drainage bin (3) bottom is provided with ash gate (6) and discharging opening (5), ash gate (6) can adopt pneumatic or hydraulic pressure is controlled, drainage bin (3) inwall is provided with bleed element (4) and is connected with gravity flow water pipe (8), gravity flow water pipe (8) is gone up load water valve (9), the pump mouth of jetting aspirator (7) is communicated with bleed element (4) by bleed pipe (20), and the delivery port of jetting aspirator (7) is communicated with drainpipe (10).The water inlet of jetting aspirator (7) links to each other with water pump (14) by penstocks (15), and water pump (14) is communicated with water inlet pipe (11), on the penstocks (15) of water pump (14) check-valves is housed, and water pump (14) reverses when preventing termination of pumping.For the water of saving the water source and making full use of discharge carries out recyclingly, as shown in Figure 1, drainpipe (10) is communicated with water tank (13), and the water inlet pipe (11) that is communicated with water pump (14) also is communicated with water tank (13), and on the water inlet pipe (11) water valve (12) is housed.Also can not establish water tank (13) and establish cistern.
In order to prevent that bleed element (4) or bleed pipe (20) from stopping up, as shown in Figure 1, bleed pipe (20) is provided with bleed valve (19), on the section of the bleed pipe (20) between bleed valve (19) and bleed pipe (20) import, be communicated with recoil tube (18), penstocks (15) are provided with water intaking valve (16), be communicated with recoil tube (18) on penstocks (15) section between water intaking valve (16) and water pump (14), recoil tube (18) is provided with recoil valve (17).
The utility model mixture of stone coal and water in use enters drainage bin (3) from feed pipe (1), then, water flows out through gravity flow water pipe (8) by the bleed element (4) that drainage bin (3) inwall is provided with again, in order to accelerate the dewatering speed of drainage bin, can close gravity flow water pipe (8) by water valve (9), open bleed valve (19) again, water intaking valve (16) and water valve (12) are also opened water pump (14), make the water in the water tank (13) be drawn into penstocks (15) from water inlet pipe (11), water inlet from jetting aspirator (7) sprays in the jetting aspirator (7) again, make jetting aspirator (7) form the negative pressure of a condition of high vacuum degree to drainage bin (3), force the water on material surface in the drainage bin (3) to be sucked into rapidly in the jetting aspirator (7) through bleed element (4) and bleed pipe (20), flow into water tank (13) from delivery port rapidly through drainpipe (10), thereby quickened the dewatering speed of the material in the drainage bin (3).
