Description
One, technical field:
The utility model relates to the high-temperature liquid metal height precision quantitative discharging device in a kind of Metal Melting system.
Two, background technology:
At present, when in the Metal Melting process, requiring the discharging of high basis weight precision is arranged, more generally adopt the piston type quantitative discharging device both at home and abroad.This device mainly is made up of heating container, suction tube, piston pump, check valve and discharge nozzle, and wherein one of suction tube inserts in the heating container, and the other end connects with piston pump by check valve, and the piston below connects with discharge nozzle through check valve.This piston type quantitative discharging device adopts the reciprocating motion of piston, charging aperture one-way valve opens during suction, and discharging opening one-way valve opens during binder realizes the quantitative discharging function of molten metal by controlling liquid flow direction.Owing to there be between mutual friction mutually, wearing and tearing and piston between piston and piston sleeve and piston sleeve expanding with heat and contract with cold and differ at high temperature to problem, cause this kind device accuracy of manufacture and manufactured materials to be had relatively high expectations, and this piston type drawing mechanism is shorter service life.
Three, summary of the invention:
The purpose of this utility model provides a kind of easy to manufacture, cost is lower, quantitative accuracy is higher high-temperature metal liquid quantitative discharging device.
Concrete scheme of the present utility model is: comprise heating container, suction tube, discharge nozzle, it is characterized in that: between suction tube, forcing pipe, negative pressure pipe and discharge nozzle, be provided with quantitative pot, the top of quantitative pot is provided with three on-off valves, and the below of quantitative pot is provided with an on-off valve; Wherein quantitative pot top connects with forcing pipe by middle on-off valve, and the on-off valve by both sides connects with suction tube and negative pressure pipe respectively, on the negative pressure pipe liquid level sensor is installed; The quantitative pot below connects with discharge nozzle by on-off valve.
Adopt such scheme, simple and reliable for structure, easy to manufacture, low cost of manufacture, working service is convenient, and the life-span is longer, and it can keep higher quantitative accuracy, has avoided the generation of fretting wear again.
Four, description of drawings:
Fig. 1 is an overall structure schematic diagram of the present utility model, also is a kind of embodiment of the present utility model.
Five, the specific embodiment:
As shown in Figure 1: the utility model is mainly by comprising heating container 1, suction tube 2, forcing pipe 3, negative pressure pipe 4, negative pressure pump 5, liquid level sensor 6, discharge nozzle 7, on-off valve 8,9,10,12 and quantitative pot 11 are formed, architectural feature of the present utility model is: be provided with quantitative pot 11 between suction tube 2, forcing pipe 3, negative pressure pipe 4 and discharge nozzle 7, the top of quantitative pot 11 is provided with three on-off valves 8,9,12, and the below of quantitative pot 11 is provided with an on-off valve 10; Wherein quantitative pot 11 tops connect with forcing pipe 3 by middle on-off valve 9, and the on-off valve 12,8 by both sides connects with suction tube 2 and negative pressure pipe 4 respectively, and liquid level sensor 6 is installed on negative pressure pipe 4; Quantitative pot 11 belows connect with discharge nozzle 7 by on-off valve 10.
On-off valve among the utility model embodiment (8,9,10,12) adopts ball valve or gate valve.
The utility model is performed such work: during suction first, on-off valve 12 and 8 is opened, on-off valve 9 and 10 is closed, negative pressure pump 5 starts the generation negative pressure, metal liquid in the heating container 1 sucks quantitative pot 11 at the suction tube 2 that negative pressure forms, treat to enter negative pressure pipe 4 again after quantitative pot 11 is filled, the metal liquid liquid level sensor 6 in the negative pressure pipe 4 of flowing through, sensor 6 provides signal, shut off valve 12, valve 8 and negative pressure pump 5, quantitative pot 11 spaces of being sealed at valve 12, valve 9, valve 8, valve 10 have been full of quantitative metal liquid to be discharged.During discharging; open valve 9 and valve 10; the protective gas of pressurization is pressed into from forcing pipe 3, will all go out through discharge nozzle 7 pressures by quantitative metal liquid to be discharged in quantitative pot 11 spaces that valve 12, valve 9, valve 8, valve 10 are sealed, thereby realize the cyclic process of a suction and quantitative discharging.Once more during suction, shut off valve 9, valve 10, open valve 12, valve 8, the liquid level that all is lower than heating container 1 when quantitative pot 11 and valve 12, valve 9, valve 8 down in limited time, because of the siphonage in the suction tube 2, need not open negative pressure pump 5, the metal liquid in the heating container 1 can suck quantitative pot 11 and negative pressure pipe 4 through suction tube 2 under the effect of siphon power, when treating that liquid level etc. in negative pressure pipe 4 is higher than liquid level in the heating container 1, the suction process is promptly finished automatically.When quantitative pot 11 and valve 12, valve 9, valve 8 all deploy be higher than heating container 1 liquid level down in limited time, because of the siphonages in the suction tube 2 lost efficacy, still need be the same by suction first, open negative pressure pump 5 and finish the suction process.
