Rectifying column end socket is set, the exchanger head and rectifying column end socket be fixedly connected by connecting tube, the heat exchanger and
Rectifying column is attached in side using fixing piece.However, the device is by L-type plate-like piece heat exchanging device and rectifying column in side
Face progress is affixed, is easy to generate to loosen in another side to deform, affects the using effect of product, shorten service life.And
And inconvenience is brought to maintenance using welding between heat exchanger and rectifying column.
Utility model content
To solve the above-mentioned problems, the utility model devises the connection structure of a kind of rectifying column and heat exchanger, structure jail
Gu being not easy to loosen, and easy to disassemble, easy to maintenance, the production cost of equipment is saved, service life is extended.
The technical solution of the utility model are as follows:
A kind of connection structure of rectifying column and heat exchanger including the heat exchanger being arranged in cold insulated cabinet and is set to described
Rectifying column above heat exchanger, the diameter of the rectifying column are greater than the transverse width of the heat exchanger, the top of the heat exchanger
Hemispheric exchanger head is set, and hemispheric rectifying column end socket, the exchanger head is arranged in the bottom of the rectifying column
It being connected with the rectifying column end socket by connecting tube, the connecting tube is cylinder type hollow pipe, up and down two including threaded connection
Part, the lower part connecting tube and the exchanger head consolidate, and the upper part connecting tube and the rectifying column end socket are solid
Knot, the outside of the connecting tube are equipped with sealing ring and sealing ring are first disposed therein the outer of a part before upper and lower two parts connection
Sealing ring is moved at sealing by side after upper and lower two parts connection.
The sealing ring is elastic rubber ring, and sealing effect is good.
Further, U-shaped fixing piece is equipped between the heat exchanger and the rectifying column, the heat exchanger is arranged described
In the groove of U-shaped fixing piece, the upper both ends of the U-shaped fixing piece are equipped with fixing threaded hole, and the two sides of the rectifying column are equipped with and institute
The corresponding fixing bolt of fixing threaded hole is stated, the fixing bolt is threadedly coupled with nut, and sound construction is not easy to loosen, and
It is easy to disassemble, easy to maintenance.
Further, the heat exchanger and the rectifying column are by the concentric connection of the connecting tube, so that the two weight
The heart is maintained at same plane as far as possible, to guarantee the stationarity of equipment.The length and width of ice chest is effectively reduced, reduces cold insulation material
Laying, to save the production cost of equipment.
Utility model has the advantages that sound construction, is not easy to loosen, and easy to disassemble, easy to maintenance, saves and set
Standby production cost, extends service life.
The utility model is described in further detail with reference to the accompanying drawings and examples.
