Description
Technical field
The utility model is related to material transportation art, specifically a kind of metrifonate production elevated dosing vessel.
Background technology
Metrifonate is a kind of less toxic organophosphorus insecticide, and most of domestic manufacturer is using phosphorus trichloride, trichloroacetaldehyde, methanol
Three kinds of raw materials of continuity method synthesis technology, metrifonate production first squeeze into elevated dosing vessel when feeding intake, and then pass through rotor according to the ratio
Flowmeter control, which matches, to feed intake, and measuring tank need to control meticulously when stocking up, and the careless slightly stock that just will appear is excessive, and it is existing to overflow race material
As causing environmental pollution, human casualty accident can be caused when serious.
Invention content
The purpose of this utility model is to provide a kind of metrifonate production elevated dosing vessel.
What the purpose of this utility model was realized in：
A kind of metrifonate production elevated dosing vessel, including elevated dosing vessel, the pump housing and pass through the pump housing and elevated dosing vessel
The raw material storage tank of the charge door connection at top, the connecting pipe between the elevated dosing vessel and the pump housing are equipped with travel switch,
Elevated dosing vessel is internally provided with floating drum, and floating drum is connect by travel switch with the pump housing, and elevated dosing vessel side wall upper part is provided with excessive
Flow tube, overflow pipe are connected by pipeline with raw material storage tank.
The elevated dosing vessel bottom is equipped with discharging hole, and the discharging hole is connect by valve with raw material storage tank.
The elevated dosing vessel is equipped with the discharge port for raw material to be discharged.
The overflow pipe gradient is not less than 10%.
The elevated dosing vessel is vertical, and bottom is flat or round or taper.
The utility model has the beneficial effects that：The utility model is simple in structure, low manufacture cost, simple to operate, when
When liquid level not up to guards against liquid level in elevated dosing vessel, floating drum impact stroke switch, travel switch normally-closed contact is closed, pump housing fortune
Become a full member normal charging；When liquid level reaches warning liquid level in elevated dosing vessel, travel switch normally-closed contact disconnects, and the pump housing stops fortune
Turn, it is excessive that stock can be prevented.To prevent travel switch damage from causing to occur overflowing to run material, elevated dosing vessel setting has one
The overflow pipe of grade, overflow pipe are connected to raw material storage tank, unobstructed when excessive convenient for stock to enter raw material storage tank.
Description of the drawings
Fig. 1 is the structural schematic diagram of the utility model embodiment 1；
In figure：Elevated dosing vessel 1, floating drum 2, the pump housing 3, raw material storage tank 4, overflow pipe 5, row travel switch 6, discharging hole 7 go out
Material mouth 8.
Specific implementation mode
Embodiment 1：
Below in conjunction with attached drawing, the utility model is described in further detail.
As shown in Figure 1, a kind of metrifonate production elevated dosing vessel, including elevated dosing vessel 1, the pump housing 3 and pass through the pump housing 3
The raw material storage tank 4 being connect with the charge door 9 at 1 top of elevated dosing vessel, the connecting tube between the elevated dosing vessel 1 and the pump housing 3
Road is equipped with travel switch 6, and elevated dosing vessel 1 is internally provided with floating drum 2, and floating drum 2 is connect by travel switch 6 with the pump housing 3, and height is worked as
When liquid level not up to guards against liquid level in the measuring tank 6 of position, 2 impact stroke switch 6 of floating drum, 6 normally-closed contact of travel switch is closed, the pump housing
3 work well charging；When liquid level reaches warning liquid level in elevated dosing vessel 1,6 normally-closed contact of travel switch disconnects, and the pump housing 3 stops
It only operates, it is excessive that stock can be prevented.1 side wall upper part of elevated dosing vessel is provided with overflow pipe 5, and 5 gradient of the overflow pipe ≮
10%, overflow pipe 5 is connected by pipeline with raw material storage tank 4, unobstructed when excessive convenient for stock to enter raw material storage tank 4, avoids race material existing
As occurring, it is beneficial to environmental protection.
1 bottom of the elevated dosing vessel is equipped with discharging hole 7, and the discharging hole 7 is connect by valve with raw material storage tank 4, institute
Elevated dosing vessel 1 is stated equipped with the discharge port 8 for raw material to be discharged；The elevated dosing vessel 1 is vertical, and bottom is flat.
Embodiment 2：
A kind of metrifonate production elevated dosing vessel of the utility model is differed only in embodiment 1：The high-order meter
Measuring tank 1 is vertical, and bottom is round or taper.
The utility model is simple in structure, low manufacture cost, simple to operate, when liquid level is not up to warned in elevated dosing vessel
When guarding against liquid level, floating drum impact stroke switch, travel switch normally-closed contact is closed, and the pump housing works well charging；Work as elevated dosing vessel
When interior liquid level reaches warning liquid level, travel switch normally-closed contact disconnects, and the pump housing shuts down, and it is excessive can to prevent stock.For
Prevent travel switch damage from causing to occur overflowing to run material, overflow pipe of the elevated dosing vessel setting with certain slope, overflow pipe connects
It is connected to raw material storage tank, it is unobstructed when excessive convenient for stock to enter raw material storage tank.
