Efficiently can clear up the pesticide producing system of residual liquor in pipeline
Technical field
The utility model belongs to pesticide producing equipment technical field, is specifically related to a kind of pesticide producing system efficiently can clearing up residual liquor in pipeline.
Background technology
In the production run of agricultural chemicals, with centrifugal pump, reacted material is squeezed in storage tank complete reaction in reactor after, carry out follow-up compounding ingredient, in order to prevent the cross pollution between liquid, under normal circumstances, liquid residual in reactor inwall and pipeline is needed to carry out emptying process, thus in discharge line, make pipeline noresidue, but this method is time-consuming, efficiency is low, and the residual liquor in pipeline can not be discharged completely.
Utility model content
Technical problem to be solved in the utility model be in existing pesticide producing process to the shortcoming that the expulsion efficiency of residual liquor in pipeline is low and time-consuming, a kind of pesticide producing system efficiently can clearing up residual liquor in pipeline is provided.
For solving the problems of the technologies described above, the utility model is by the following technical solutions: a kind of pesticide producing system efficiently can clearing up residual liquor in pipeline, comprise reactor, described reactor is connected with storage tank by discharge pipe, discharge pipe is provided with centrifugal pump, described pesticide producing system also comprises air compressor, and the gas exhaust duct of air compressor communicates with reactor.
Described gas exhaust duct is provided with vent valve.
Laminating inwall place, described reactor top is provided with gas blow pipe, and gas blow pipe communicates with gas exhaust duct, and gas blow pipe is provided with the venthole of exhaust downwards.
Described discharge pipe and storage tank seal UNICOM and discharging opening is positioned at more than the most high liquid level (HLL) of storage tank.
Described discharge pipe is provided with relief pipeline, and relief pipeline is provided with blowdown valve.
Described storage tank top is provided with tensimeter.
Described pesticide producing system also comprises controller, and tensimeter and blowdown valve are electrically connected with controller respectively, and when the pressure in storage tank is greater than setting value, blowdown valve is automatically opened and carried out pressure release under the effect of controller, ensures safety in production.
The beneficial effects of the utility model: the pressurized air that air compressor produces passes in reactor by the pesticide producing system efficiently can clearing up residual liquor in pipeline of the present utility model, liquid residual in pipeline is efficiently cleared up and reclaimed, prevent between different liquid, cross pollution occurring in reactor and storage tank, ensure noresidue in pipeline, easy and simple to handle, efficiency is high, practical; Reactor upper end inwall is set up gas blow pipe and is utilized pressurized air to blow off the liquid on reactor inwall to the discharge outlet of reactor bottom further, thus clears out of reactor, ensures noresidue in reactor; By controller, the pressure in storage tank is detected, and automatically control the unlatching of blowdown valve, the pressure in storage tank is in range of set value, thus ensure safety in production.

Fig. 1 is structural representation of the present utility model.
Embodiment
As shown in Figure 1, a kind of pesticide producing system efficiently can clearing up residual liquor in pipeline, comprise reactor 1, reactor 1 is connected with storage tank 3 by discharge pipe 2, discharge pipe 2 is provided with centrifugal pump 4, this pesticide producing system also comprises air compressor 5, the gas exhaust duct 6 of air compressor 5 communicates with reactor 1, gas exhaust duct is provided with vent valve 7, laminating inwall place, reactor 1 top is provided with gas blow pipe 8, gas blow pipe 8 communicates with gas outlet 6 road, gas blow pipe 8 is provided with the venthole 9 of exhaust downwards, pressurized air is utilized to blow off to the discharge outlet of reactor bottom by the liquid on reactor 1 inwall further, thus clear out of reactor, ensure noresidue in reactor 1.
Discharge pipe 2 and storage tank 3 seal UNICOM and discharging opening 10 is positioned at more than the most high liquid level (HLL) of storage tank 3, prevents the pressure in storage tank from crossing in ambassador's liquid suck-back return pipe road; Discharge pipe 2 is provided with relief pipeline 11, relief pipeline 11 is provided with blowdown valve 12, storage tank 3 top is provided with tensimeter 13, pesticide producing system also comprises controller 14, tensimeter 13 and blowdown valve 12 are electrically connected with controller 14 respectively, and when the pressure in storage tank 3 is greater than setting value, the pressure probe of tensimeter 13 sends signal to controller 14, thus blowdown valve 12 is automatically opened under the effect of controller 14 carry out pressure release, ensure safety in production.
The pressurized air that air compressor produces passes in reactor by the pesticide producing system efficiently can clearing up residual liquor in pipeline of the present utility model, liquid residual in pipeline is efficiently cleared up and reclaimed, prevent between different liquid, cross pollution occurring in reactor and storage tank, ensure noresidue in pipeline, easy and simple to handle, efficiency is high, practical.
