The high-quality selected natural siliceous sand of precoated sand generally use is roughing sand, with it with thermoplastic phenolic resin, methenamine
And the raw materials such as reinforcing agent are made by certain technique.Precoated sand is widely used in motor cylinder block, cylinder cap, inlet manifold, all kinds of
The production of the various intricate castings such as pipe fitting, the pump housing.Precoated sand generally uses thermoplastic phenolic resinoid as binder at present,
Using methenamine as curing agent, curing agent generally use methenamine aqueous solution is added in production process into sand mixer,
It is a kind of viscous liquid.It is usually that manual weighing adds manually to add the mode of curing agent in production process into sand mixer at present
Add, there are the problem of have：Manual weighing is inaccurate in the presence of metering, and feeding manually, there are feed times inaccurately, easily to leak
The problems such as being subject to and be unhygienic.
Utility model content
The purpose of this utility model is：For problems of the prior art, a kind of simple in structure, realization side is provided
Just, cost is not high and can automatically and accurately add the viscous liquid metering feeding device of curing agent when using into sand mixer.
The technical solution of the utility model is：The viscous liquid metering feeding device of the utility model, including liquid material container
And sand mixer, above-mentioned liquid material container are equipped with liquid outlet, sand mixer is equipped with inlet, is structurally characterized in that：Further include pump, feeding gas
Dynamic valve, hopper, discharging pneumatic operated valve, liquid-transport pipe-line and threeway；
Said pump, charging pneumatic operated valve and discharging pneumatic operated valve are respectively equipped with inlet and liquid outlet；Hopper be equipped with liquid material into
Outlet；The inlet of said pump is connected by liquid-transport pipe-line with the liquid outlet of above-mentioned liquid material container；Feed the inlet of pneumatic operated valve
It is connected with the liquid outlet of pump by liquid-transport pipe-line；Feed the liquid outlet of pneumatic operated valve, the liquid material inlet and outlet of hopper and discharging gas
The inlet of dynamic valve is interconnected by threeway and liquid-transport pipe-line；The liquid outlet of discharging pneumatic operated valve passes through liquid-transport pipe-line and above-mentioned sand mixer

Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model.
Reference numeral in above-mentioned attached drawing is as follows：
Liquid material container 1, pump 2 feed pneumatic operated valve 3, and hopper 4, discharge pneumatic operated valve 5, liquid-transport pipe-line 6, threeway 7, sand mixer
8。
Specific implementation mode
Utility model will be further described in detail below with reference to the attached drawings and specific embodiments.
（Embodiment 1）
See Fig. 1, the viscous liquid metering feeding device of the present embodiment, mainly by liquid material container 1, pump 2, charging pneumatic operated valve
3, hopper 4, discharging pneumatic operated valve 5, liquid-transport pipe-line 6, threeway 7 and sand mixer 8 form.
Liquid material container 1 is equipped with liquid outlet, and pump 2, charging pneumatic operated valve 3 and discharging pneumatic operated valve 5 are respectively equipped with inlet and go out liquid
Mouth, hopper 4 are imported and exported equipped with liquid material, and sand mixer 8 is equipped with inlet.
The inlet of pump 2 is connected by liquid-transport pipe-line 6 with the liquid outlet of liquid material container 1；The inlet for feeding pneumatic operated valve 3 is logical
Liquid-transport pipe-line 6 is crossed with the liquid outlet of pump 2 to be connected；Feed the liquid outlet of pneumatic operated valve 3, the liquid material inlet and outlet of hopper 4 and discharging
The inlet of pneumatic operated valve 5 is interconnected by threeway 7 and liquid-transport pipe-line 6；The liquid outlet of discharging pneumatic operated valve 5 is by liquid-transport pipe-line 6 and mixes
The inlet of sand machine 8 is connected.
The viscous liquid metering feeding device of the present embodiment contains precoated sand when in use, in liquid material container 1 and produced
The methenamine aqueous solution as curing agent added into sand mixer 8 is needed in journey, is a kind of viscous liquid.It needs to add
When curing agent, discharging pneumatic operated valve 5 is first closed, opens charging pneumatic operated valve 3, then starts pump 2, pump 2 holds viscous liquid from liquid material
Device 1 pumps to hopper 4 through liquid-transport pipe-line 6, charging pneumatic operated valve 3, threeway 7, when the viscous liquid in hopper 4 reaches set amount
When, pump 2 and charging pneumatic operated valve 3 are closed, discharging pneumatic operated valve 5 is opened and the viscous liquid after the metering of hopper 4 is transported to mulling
In machine 8, so recycle.
Above example is the explanation rather than limitations of the present invention to specific embodiment of the present utility model,
