Waste alcohol sediment separation device for sausage casing residues

Abstract

The invention relates to a heparin sediment and waste alcohol separation device. The heparin sediment and waste alcohol separation device comprises a desorption tank, an alcohol sedimentation tank, a waste alcohol storage tank, a gas storage tank and a vacuum pump, wherein the lower end of the desorption tank is connected with the upper end of the alcohol sedimentation tank by a pipeline; the upper end of the alcohol sedimentation tank is provided with a vacuumizing pipe and the other end of the vacuumizing pipe is connected with the upper end of the gas storage tank; the upper end of the gas storage tank is connected with the vacuum pump by a pipeline; a waste alcohol recycling pipe is arranged at the position, close to the lower end, of one side of the alcohol sedimentation tank; the waste alcohol recycling pipe is communicated to the upper end of the waste alcohol storage tank and is provided with a conveying pump; the lower end of the alcohol sedimentation tank is provided with a sediment discharging pipe; the sediment discharging pipe is provided with a discharging valve; and a sediment recycling bucket is arranged at the lower end of the sediment discharging pipe. The heparin sediment and waste alcohol separation device has the advantages that desorption liquid can be rapidly and sufficiently conveyed to the sedimentation tank and the production efficiency is improved; an alcohol and heparin sediment mixed solution can be effectively separated on the basis of omission of a power device, and an alcohol solution is recycled in time; and energy conservation and emission reduction can be realized, and the production cost can be effectively reduced.

Description

technical field [0001] The invention relates to the field of separating heparin precipitation and its waste alcohol, in particular to a separation device for heparin precipitation and its waste alcohol. Background technique [0002] In the production process of heparin, after the resin adsorbed with heparin is desorbed, it takes a long time for the desorption liquid to reach the precipitation tank when ethanol precipitates the heparin, which affects the production efficiency, and the desorption liquid is not easy to enter the precipitation tank when it is adsorbed in the resin, which affects the output. Repeat The operation will increase the production cost; after the ethanol precipitation is completed, the separation of waste alcohol and heparin precipitation is generally done by centrifugation. However, the precipitation liquid contains a large amount of salt, which is highly corrosive to the centrifugal equipment, and it is easy to recover heparin after centrifugation. Lo...

Repeat The operation will increase the production cost; after the ethanol precipitation is completed, the separation of waste alcohol and heparin precipitation is generally done by centrifugation. However, the precipitation liquid contains a large amount of salt, which is highly corrosive to the centrifugal equipment, and it is easy to recover heparin after centrifugation. Loss, the operation of disassembling the centrifugal equipment is also very cumbersome, and the power of the centrifugal equipment is relatively large, which increases the production cost
