Abstract

The utility model discloses a quick refrigerating secondary filtering unit, and comprises a refrigerating unit, a refrigerant tank, a primary heat exchanger, a secondary heat exchanger, a primary filtering machine and a secondary filtering machine. The utility model first refrigerates the refrigerant in the refrigerant tank, uses a cooling tower to cool the refrigerating unit with a good refrigerating effect, and enables the refrigerant in the refrigerant tank to reach the desired temperature quickly to enter the secondary heat exchanger for heat exchange with the filtered substances so that the filtered substances quickly arrive at the required temperature for refrigerated filtering. The filtered substances are first filtered in the primary filtering machine, and then in the secondary filtering machine while the filtered substances still remain at the temperature required for refrigerated filtering. Thus, the utility model greatly enhances the filtering quality with the dual refrigerated filtering.

Description

The cold cascade filtration unit of speed

Technical field

The utility model relates to a kind of filter

Background technology

The freezing and filtering machine that uses in food_beverage industry at present is because the chilling rate of filtrate is slow, the temperature requirement of the freezing and filtering that is difficult to reach desirable, and be once to filter, so filter effect is not fine.

The utility model content

The purpose of this utility model provides the cold cascade filtration unit of a kind of speed.

The purpose of this utility model realizes in the following way: the cold cascade filtration unit of a kind of speed, comprise refrigeration unit, the refrigerant jar, the one-level heat exchanger, two-stage heat exchanger, the one-level filter, the cascade filtration machine, feed pipe is through inlet valve, feed pump is to the one-level heat exchanger, come out to come out after the one-level strainer valve from the one-level filter from the one-level heat exchanger after the one-level crossover valve to two-stage heat exchanger, comes out the back to the one-level filter from two-stage heat exchanger, circulating pump divides two-way, one the tunnel on cut-off valve is received pipeline between one-level crossover valve and the two-stage heat exchanger, the one tunnel through the cascade filtration valve to the cascade filtration machine; Come out after discharging pump divides two-way from the cascade filtration machine, the one tunnel through circulating valve to the one-level filter, the one road to the one-level heat exchanger, connects bleeder valve to discharge nozzle after the one-level heat exchanger comes out; The refrigerant pipe comes out to connect the refrigerant jar from refrigeration unit, come out to divide two-way from the refrigerant jar through one-level refrigerant valve, refrigerant pump, one the tunnel through secondary refrigerant valve to two-stage heat exchanger, from the two-stage heat exchanger back tieback refrigeration unit of coming out, the one tunnel on return valve is connected on refrigerant pipe between two-stage heat exchanger and the refrigeration unit [1].

The cooling tube of cooling tower connects refrigeration unit through cooling valve, water supply pump, tieback cooling tower after coming out from refrigeration unit.

The utility model is owing to the refrigerant refrigeration of elder generation to the refrigerant jar, and refrigeration unit is adopted the cooling tower cooling, good refrigeration effect, can make the refrigerant in the refrigerant jar reach needed temperature rapidly, enter two-stage heat exchanger and filtrate and carry out heat exchange, can make filtrate drop to the temperature requirement of freezing and filtering rapidly, in the one-level filter, carry out freezing and filtering, filtrate after one-level is filtered can also remain on the temperature requirement of freezing and filtering, in the cascade filtration machine, carry out secondary filter again, through twice freezing and filtering, can improve filter quality greatly.
