SU129948A1 - Method of transferring liquid, hot, easily penetrating chemical mixtures, for example, diphenyl mixture - Google Patents

Description

When pumping liquid, hot, easy-penetrating chemical mixtures, such as diphenyl SMSCs, is carried out by known methods, the worker is placed on the fumes. This is due to the fact that, due to the fact that the case and the pores of the case of the case, I miss the pairs of the Mixture.

The described method eliminates this body drawback that the Transfer Pump hot mixture is placed in a closed tank, which is the same, but only cold chemical matter.

The drawing shows schematically the installation for implementation, the shadow of the described method.

In the closed tank / set the pump 2 and pour the cold chemical mixture to the level of the opening of the overflow pipe 3.

The hot, easily penetrating chemical mixture is pumped by pump 2 from the inlet 4, IB outflow 5. When pumping, some of the se inevitably leaks through the incompetence in the bowl, but is mixed with the cold mixture in the reservoir.

An excess of the mixture in the tank periodically returns the i5 system, g of access from the overflow pipe 3 to the inlet pipe 4.

To maintain the temperature of the cold chemical mixture at a given level in the tank / install the coil 6, through which hot water flows.

Subject of reproduction

The method of transferring liquid, hot, and penetrating chemical mixtures, such as diphenyl mixture, from that, and so on, to prevent the release of vapor from the mixture through the glands and pores of the pump casing to working pumping, I mix the pump according to N 129948-2 in a closed tank with the same cold mixture, the temperature of which is maintained and set, for example, by means of cooling water circulating in a cold mixture tank.
