Abstract
The utility model relates to a condenser of a rotary evaporator. The condenser of the rotary evaporator comprises a condensation pipe, a dry ice freezing device, a silica gel flexible pipe and a peristaltic pump, wherein a water inlet and a water outlet are formed in the pipe wall of the condensation pipe; a pipe cavity is provided with a vacuumizing port; the dry ice freezing device is a freezing liquid storage tank internally provided with a filter screen bag; the silica gel flexible pipe is connected with the condensation pipe and the dry ice freezing device; the peristaltic pump is arranged on the silica gel flexible pipe and provides power for conveying freezing liquids. Compared with the prior art, the dry ice provided by the utility model is arranged in the filter screen bag for refrigeration; freezing liquids are conveyed into the condensation pipe by utilizing the power of the peristaltic pump; the filter screen bag filters impurities mixed in dry ice, so that the impurities cannot enter the condensation pipe to form blocking; the condenser of the rotary evaporator also has the advantages of good refrigerating effect, uniform speed for conveying freezing liquids and the like.
Description
Technical field
The utility model relates to a kind of condenser, especially relates to a kind of condenser for Rotary Evaporators.
Background technology
Rotary Evaporators is the important instrument of industry research and production such as chemical industry, medicine, biology, is mainly used in a large amount of easy volatile solvent of continuous still under reduced pressure.Its structure comprises: distilling flask, thermostat water bath, condenser, drawdown pump and accept flask.Basic principle is decompression distillation, and namely under reduced pressure, distilling flask rotates continuously, makes solvent distill.
Rotary Evaporators is lower for the rate of recovery of some lower boiling volatile solvents, existing condenser, the general cryogenic liquid that adopts circulates, the replacing frozen water that need not stop just can reach the effect of cooling, use circulating pump not only to make complex structure, and can strengthen energy loss, sneak into impurity in the frozen water easily, cause that condenser pipe stops up, and reduces condensation effect.
The utility model content
The purpose of this utility model is exactly the Rotary Evaporators condenser that provides a kind of good refrigeration effect, freezing liquid at the uniform velocity to carry, avoid pipeline blockage for the defective that overcomes above-mentioned prior art existence.
The purpose of this utility model can be achieved through the following technical solutions:
A kind of Rotary Evaporators condenser comprises:
Condenser pipe: offer water inlet and delivery port on the tube wall, tube chamber is provided with vacuum orifice;
The dry ice refrigerating plant: in be provided with the freezing liquid holding vessel of filter screen pocket;
Silica gel hose: carry the flexible pipe of freezing liquid, connect condenser pipe and dry ice refrigerating plant;
Peristaltic pump: being arranged on the silica gel hose to carry for freezing liquid provides power, and the speed that guarantees to carry freezing liquid is the liquid body viscosity influence not, and the peristaltic pump rotating speed is generally chosen 200～300rpm.
Described freezing liquid holding vessel is the 316L stainless steel, splendid attire freezing liquid in the freezing liquid holding vessel.
Described filter screen pocket be the aperture greater than 100 purpose stainless steel filter screens, prevent that the impurity of sneaking in the dry ice from stopping up condenser pipe.
The dry ice that splendid attire freezes and handles freezing liquid in the described filter screen pocket, its refrigeration is 1.5 times of frozen water.
Described silica gel hose forms a closed circuit between condenser pipe and dry ice refrigerating plant.
Compared with prior art, the utility model places the filter screen pocket to freeze on dry ice, utilizes the power of peristaltic pump that freezing liquid is conveyed into condenser pipe, and the filter screen pocket filters the impurity that is mixed with in the dry ice, makes it can not enter condenser pipe and forms obstruction, has the following advantages:
One, good refrigeration effect: the dry ice refrigeration effect is 1.5 times of frozen water.
Two, freezing liquid is at the uniform velocity carried: peristaltic pump provides fixing speed to carry freezing liquid, reduces the influence of liquid viscosity.
Three, avoid pipeline blockage: the adding of filter screen pocket, guarantee the clean of freezing liquid, can not stop up condenser pipe.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Among the figure, 1 is that condenser pipe, 2 is that vacuum orifice, 3 is that condenser pipe delivery port, 4 is that condenser pipe water inlet, 5 is that peristaltic pump, 6 is that silica gel hose, 7 is that dry ice refrigerating plant, 8 is that dry ice refrigerating plant water inlet, 9 is that dry ice refrigerating plant delivery port, 10 is that freezing liquid holding vessel, 11 is the filter screen pocket.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
A kind of Rotary Evaporators condenser, its structure mainly are made up of condenser pipe 1, dry ice refrigerating plant 7, silica gel hose 6 and peristaltic pump 5 as shown in Figure 1.Offer condenser pipe water inlet 4 and condenser pipe delivery port 3 on the tube wall of condenser pipe 1, tube chamber is provided with vacuum orifice 2.Dry ice refrigerating plant 7 is equipped with the freezing liquid holding vessel 10 of filter screen pocket 11 in being.Freezing liquid holding vessel 10 is the 316L stainless steel, splendid attire freezing liquid in freezing liquid holding vessel 10.Filter screen pocket 11 be the aperture greater than 100 purpose stainless steel filter screens, prevent that the impurity of sneaking in the dry ice from stopping up condenser pipe 1.The dry ice that splendid attire freezes and handles freezing liquid in the filter screen pocket 11, its refrigeration is 1.5 times of frozen water.Silica gel hose 6 is flexible pipes of carrying freezing liquid, connects condenser pipe 1 and dry ice refrigerating plant 7.Silica gel hose 6 forms a closed circuit between condenser pipe 1 and dry ice refrigerating plant 7, initiating terminal connects dry ice refrigerating plant delivery port, enter in the condenser pipe 1 through condenser pipe water inlet 4, pass condenser pipe 1 by condenser pipe delivery port 3 then, the terminal dry ice refrigerating plant water inlet 8 that connects.Peristaltic pump 5 is arranged on the silica gel hose 6 to carry for freezing liquid provides power, and the speed that guarantees to carry freezing liquid is the liquid body viscosity influence not, and the peristaltic pump rotating speed is generally chosen 200～300rpm.The utility model places filter screen pocket 11 refrigeration with dry ice, utilizes the power of peristaltic pump 5 that freezing liquid is conveyed into condenser pipe 1, and filter screen pocket 11 filters the impurity that is mixed with in the dry ice, it can not be entered form obstruction in the condenser pipe 1.
