Abstract
The utility model discloses a helical pipe rotary thin-film evaporator applicable for the high-viscosity feed liquid, comprising an evaporating tank and an evaporating pipe. The utility model is characterized in that the interior of the evaporating tank is longitudinally provided with a rotating shaft fixedly connected with a speed reducer out of the tank and a motor; the rotating shaft is helically winded with the evaporating pipe movably connected with a pipeline for the high-temperature steam or the liquid out of the tank. The utility model has the advantages of simple structure, small size, big evaporation area, high heat exchange coefficient, less heat loss, strong production capacity, less feed liquid back mixing, etc.
Description
The utility model belongs to the liquid concentration technical field, specifically a kind of spiral tube evaporator that rotates in the feed liquid of need evaporation.
As everyone knows, in the production in fields such as chemical industry, food, pharmacy, the production link that evaporation process is wherein indispensable and workload is bigger.At present general evaporimeter mainly contains: the decompression pot, rise film, falling liquid film, centrifugal or various types of evaporimeters such as economic benefits and social benefits, multiple-effect.Above-mentioned various evaporimeters all have its characteristics separately, but its weak point is also arranged, and are low as the coefficient of heat transfer, heat loss is big and disengagement area is little, and its effect of moisture content that especially is used for evaporating in the high viscosity feed liquid is poorer.
The purpose of this utility model provides a kind of helix tube type rotary film evaporator that is used for evaporating feed liquid.
The purpose of this utility model is achieved in that it includes evaporator tank, evaporation tube, it is characterized in that being vertically arranged with a turning cylinder of fixedlying connected with reductor, motor outside the groove in the inside of evaporator tank, on turning cylinder spiral be wound with groove outside high-temperature steam or the liquid line evaporation tube of living and being connected.During operation, the feed liquid that will need earlier to concentrate is squeezed in the evaporator tank, and starter motor is connected high-temperature steam, and then turning cylinder drive evaporation tube rotates in feed liquid, thereby has reached the purpose that concentrates.
Therefore the utility model has the following advantages because the mode that adopts evaporation tube to rotate in feed liquid is evaporated:
1, simple in structure, volume is little, and disengagement area is big, and production capacity is strong.
2, biofilm is even, and constantly changes liquid film, coefficient of heat transfer height, and heat loss is little.
3, this structure is specially adapted to concentrating in the bigger feed liquid production process of viscosity, as long as feed liquid has flowability, and just can normal biofilm.
4, because the evaporation tube that feed liquid is being rotated is divided into a plurality of junior units, and then feed concentration is pressed the ladder form, and concentration progressively improves, so the feed liquid back-mixing is little in the groove.
Resistance was little when 5, evaporation tube rotated in feed liquid, and it is low to consume energy.
6, the utility model just can be worked at 40 ℃, and the effective ingredient of thermal sensitivity feed liquid is not produced destruction.
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is a structural representation of the present utility model.
By shown in Figure 1,1 is evaporator tank, in evaporator tank, be full of to have and need concentrated feed liquid (as the Chinese medicine feed liquid), one hollow turning cylinder 2 vertically is installed in evaporator tank 1, this turning cylinder is fixedlyed connected with gearbox 4, the motor 5 in the evaporator tank outside, spiral uniform winding has evaporation tube 3 on turning cylinder, and this evaporation tube is to live with the high-temperature steam pipeline in the groove external system by hollow turning cylinder in being connected (being flexible coupling).During evaporation, first starter motor, and then by logical high-temperature steam, the evaporation tube that is flexible coupling that then is full of high-temperature steam (steam pressure generally is no more than 1 atmospheric pressure) in the turning cylinder drive pipe rotates in feed liquid, and gradually feed liquid is concentrated.
