Description

A kind of external circulation vacuum concentrator

Technical field

The utility model relates to vacuum concentrator technical field, particularly a kind of external circulation vacuum concentrator.

Background technology

Vacuum concentrator is mainly used in the recovery of the industrial organic solvents (as alcohol) such as Chinese medicine, Western medicine, glucose, wine brewing, starch, oral liquid, food, chemical industry, is applicable to the cryogenic vacuum of little heat sensitive material wide in variety in batches and concentrates.

Current vacuum concentrator, comprises heater, the evaporimeter connecting successively and is subject to flow container, between heater and evaporimeter, is connected by pipeline, is subject to be connected with condenser between flow container and evaporimeter.When work, first open the vacuum orifice being arranged on condenser, make heater and evaporimeter under vacuum state, then in heater, pass into liquid material, liquid material is heated in heater, heated liquid material enters in evaporimeter, because evaporimeter is under vacuum state, the steam forming at evaporimeter top is brought into condenser by vacuum, through cooling formation distilled water, enter and collected by flow container, and effective one-tenth of medicine after concentrated remains in heater.

But, this vacuum concentrator in the course of the work, in evaporimeter, conventionally gather some refluxes and enters the condensate liquid in evaporimeter from condenser, after condensate liquid mixes with the liquid material after heating, condensate liquid makes liquid material local temperature poor larger, finally because liquid material temperature is unbalanced, cause needing spended time from evaporimeter, to take out liquid material, then liquid material is again passed in heater and reheats liquid material temperature is heated evenly, need to repeatedly operate like this could be completely concentrated by liquid material, exist thickening efficiency low, the shortcoming that production cycle is long, so also waste labour.

And in condenser, be only provided with the condensate pipe that is parallel to one by one condenser inwall, this condensate pipe cooling range be arrangeding in parallel is little, therefore the condensed water in condensate pipe is difficult to all cooling the steam with high temperature in condenser, finally cause being subject to the extreme temperatures of flow container, very easily damage equipment.

Utility model content

The purpose of this utility model is to overcome the shortcoming of prior art, provide a kind of simple in structure, thickening efficiency is high, avoid the too high external circulation vacuum concentrator of local temperature.

The purpose of this utility model is achieved through the following technical solutions: a kind of external circulation vacuum concentrator, it comprises the heater connecting successively, pipeline I, evaporimeter, pipeline II, condenser and collecting tank, heater base is provided with discharging opening, collecting tank bottom is provided with liquid outlet, described base of evaporator and heater base are connected with return duct, return duct and evaporimeter and heater internal communication, in described condenser, be mounted with spiral-shaped condensate pipe, the mouth of pipe of condensate pipe is arranged on the bottom of condenser and is communicated with condenser is outside, the pipe tail of condensate pipe is arranged on the top of condenser and is communicated with condenser is outside, condenser overhead is provided with vacuum port, vacuum port and condenser internal communication.

Described heater bottom is tapered, and evaporimeter bottom is tapered.

It also comprises vacuum extractor, and vacuum extractor is connected with vacuum port.

The utlity model has following advantage: (1) base of evaporator of the present utility model and heater base are connected with return duct, return duct and evaporimeter and heater internal communication, thereby form outer circulation structure, when some refluxes from condenser when heater condensate liquid, the mixing of materials of condensed fluid in return duct sprays into evaporimeter and in evaporimeter, and drive the material in evaporimeter to rotate in evaporimeter, self-assembling formation stirring action, the equilibrium of whole like this material heating temperature, avoid local temperature too high, steam constantly forms distilled water through condenser and finally enters in collecting tank under vacuum condition, so loop, the final concentrate that leaves medicine in heater, concentrate can be discharged from discharging opening, there is thickening efficiency high, save labour's feature.(2) in condenser, be mounted with spiral-shaped condensate pipe, the mouth of pipe of condensate pipe is arranged on the bottom of condenser and is communicated with condenser is outside, the pipe tail of condensate pipe is arranged on the top of condenser and is communicated with condenser is outside, spiral-shaped condensate pipe is spiral, cooling range is large, condensed water in condensate pipe is easy to all cooling the steam with high temperature in condenser, thereby has avoided high-temperature steam not have complete cooling damage to be subject to the phenomenon of flow container.

The specific embodiment

Below in conjunction with accompanying drawing, the utility model is further described, protection domain of the present utility model is not limited to the following stated:

As depicted in figs. 1 and 2, a kind of external circulation vacuum concentrator, it comprises the heater 1 connecting successively, pipeline I2, evaporimeter 3, pipeline II4, condenser 5 and collecting tank 6, heater 1 bottom is provided with discharging opening 10, collecting tank 6 bottoms are provided with liquid outlet 11, described evaporimeter 3 bottoms and heater 1 bottom are connected with return duct 7, return duct 7 and evaporimeter 3 and heater 1 internal communication, in described condenser 5, be mounted with spiral-shaped condensate pipe 8, the mouth of pipe of condensate pipe 8 is arranged on the bottom of condenser 5 and is communicated with condenser 5 is outside, the pipe tail of condensate pipe 8 is arranged on the top of condenser 5 and is communicated with condenser 5 is outside, condenser 5 tops are provided with vacuum port 9, vacuum port 9 and condenser 5 internal communication.Heater 1 bottom is tapered, and evaporimeter 3 bottoms are tapered.It also comprises vacuum extractor, and vacuum extractor is connected with vacuum port 9.

The course of work of the present utility model is as follows: first start vacuum plant, vacuum plant makes heater 1 and evaporimeter 3 under vacuum state by vacuum port, then opens discharging opening 10; The mouth of pipe to condensate pipe 8 passes into condensed water, and condensed water goes out from the pipe wake flow of condenser pipe 8; Pass into after appropriate liquid material to discharging opening 10, then close discharging opening 10.Evaporimeter 3 bottoms are connected by return duct 7 with heater 1 bottom, heater 1 first half and evaporimeter 3 middle and upper part tangential directions are communicated with pipeline I2, thereby form outer circulation structure, when the material in heater 1 is in the time that heating reaches material boiling point, liquid material sprays into evaporimeter 3 from the pipeline I2 of tangential direction, the steam forming at evaporimeter 3 tops is brought condenser 5 into through pipeline II4 under vacuum condition, and steam is through the cooling formation distilled water of condenser 5, and distilled water enters collecting tank 6.Heater 1 some from condenser 5, reflux condensate liquid time, the mixing of materials of condensate liquid liquid part in return duct 7 sprays into evaporimeter 3 and evaporimeter 3, and drive material in evaporimeter 3 in the interior rotation of evaporimeter 3, self-assembling formation stirring action, the equilibrium of whole like this material heating temperature, avoid local temperature too high, material sprays into evaporimeter 3 from tangent line simultaneously, add stirring action, improve the specific area of material, the active ingredient of final liquid material is concentrated in heater 1, has the advantages that thickening efficiency is high, save labour.
