In the temperature of carrying out needing in extraction process to make the material in solid-phase extraction column keep certain, to reach the effect of best efficient extraction, that solid-phase extraction column is put into larger insulating box at present, and for convenience of observing, interpolation or the material insulating box side of taking out in solid-phase extraction column need open, be convenient for people to operate, first such insulating box has larger opening, cause the temperature in insulating box larger by externally temperature influence, when ambient temperature is too high or too low, insulating box need consume higher-wattage and regulate, cause the waste of resource and cost, and insulating box takes up room larger.
Utility model content
For the deficiencies in the prior art, the utility model provides one and takes up room little, the convenient temperature controlled in solid-phase extraction column, less by externally temperature influence, the constant temperature solid-phase extraction column economized on resources.
For achieving the above object, the utility model provides following technical scheme: a kind of constant temperature solid-phase extraction column, comprise interior pipe and the sieve plate being positioned at pipe, interior pipe is outside equipped with outer tube, be provided with gap between outer tube and interior pipe and form heat preservation sandwich layer, outer tube offers the penetrating water inlet to heat preservation sandwich layer and delivery port.
By adopting technique scheme, when extracting, by passing into temperature required water or other materials by the water inlet heat preservation sandwich layer that successively inwardly pipe and outer tube are formed, make to be full of water in heat preservation sandwich layer, unnecessary water will be flowed out by delivery port, make the water being full of steady temperature in heat preservation sandwich layer all the time, and then the temperature remained constant in ensureing in pipe, make extraction reach peak efficiency to carry out, because control temperature is for directly to control on inner pipe, nearer apart from the reactive material in interior pipe, so temperature impact when ambient temperature changes in internal pipe is very little, easy control, and just can implement without the need to larger space.
The utility model is set to further: be provided with some deflectors between inner and outer tubes.
By adopting technique scheme, deflector can carry out drainage guiding to the water passed in heat preservation sandwich layer, to make in heat preservation sandwich layer water everywhere all be changed, keeps constant temperature.
The utility model is set to further: deflector comprises the first deflector and the second deflector, first deflector is extended from top to bottom, and and between the bottom of heat preservation sandwich layer, leave the space of supplying water and passing through, second deflector is extended from bottom to top, and and between the top of heat preservation sandwich layer, leave the space of supplying water and passing through, the first deflector and the second deflector are circumferentially crisscross arranged.
By adopting technique scheme, after water is entered by water inlet, will along the first deflector and the second water conservancy diversion that deflector carries out, water carries out constantly up and down and around the motion of interior pipe circumference, flowed out, and the first deflector and the second deflector is connected to inner and outer tubes until move to delivery port position by delivery port in heat preservation sandwich layer, when taking extraction column, first deflector and the second deflector will give outer tube certain supporting role, strengthen its structural strength, more durable.
The utility model is set to further: some deflectors are arranged in the shape of a spiral, and helical form deflector and inner and outer tubes form guiding gutter.
By adopting technique scheme, the guiding gutter that spiral helicine deflector is formed can make water flow along this guiding gutter, and the water everywhere in heat preservation sandwich layer can be made equally all to change, and keeps temperature constant state.
The utility model is set to further: the sidewall of outer tube is provided with frosted layer.
By adopting above-mentioned technology which is put, frosted layer then facilitates staff's taking to extraction column, prevents skid and drop and break into pieces.
Compared with prior art, the utility model constant temperature solid-phase extraction column space is little, the convenient temperature controlled in solid-phase extraction column, less by externally temperature influence, economizes on resources.

Detailed description of the invention
Referring to figs. 1 through Fig. 4, the embodiment of the utility model constant temperature solid-phase extraction column is described further.
A kind of constant temperature solid-phase extraction column, comprise interior pipe 1 and the sieve plate 3 being positioned at pipe 1, interior pipe 1 is outside equipped with interior pipe 2, be provided with gap between interior pipe 2 and interior pipe 1 and form heat preservation sandwich layer 6, interior pipe 2 offers the penetrating water inlet 21 to heat preservation sandwich layer 6 and delivery port 22, some deflectors are provided with between pipe 1 and interior pipe 2 in the present embodiment is preferred, as shown in Figure 3, deflector comprises the first deflector 61 and the second deflector 62, first deflector 61 is extended from top to bottom, and and between the bottom of heat preservation sandwich layer 6, leave the space of supplying water and passing through, second deflector 62 is extended from bottom to top, and and between the top of heat preservation sandwich layer 6, leave the space of supplying water and passing through, first deflector 61 and the second deflector 62 are circumferentially crisscross arranged.
As shown in Figure 4, in use, water inlet 21 and delivery port 22 are coupled together by water pipe 7 by several this constant temperature solid-phase extraction columns 5 successively, be cascaded by several this constant temperature solid-phase extraction columns 5, then be connected to water tank 92 and water pump 9 by water pipe 7 again, make it form a complete circulation, in water tank 92, place temperature regulating device, can be heater strip or heating plate, the water in water tank 92 is controlled.
When extracting, the material of extraction is needed to be placed within the interior pipe 1 of several constant temperature solid-phase extraction columns 5, above sieve plate 3, then in water tank 92, carry out by water pump 9 water extracting constant temperature, make water successively by several constant temperature solid-phase extraction columns 5, in each constant temperature solid-phase extraction column 5, first water entered by water inlet 21, then flow back and forth along the first deflector 61 and the second deflector about 62, until flow to delivery port 22 place, in this process, water just all carries out temperature control to each position of whole interior pipe 1, material is made to reach best extraction temperature, improve extraction efficiency, last water, by delivery port 22 reflow tank 92 again, makes whole system form a circulation, makes water be wasted in whole process, water only carries out temperature control in internal pipe 1 position simultaneously, need consume the energy less, energy loss is few, substantially can not affect by the change of ambient temperature.
Certainly in use, also only temperature control can be carried out to a constant temperature solid-phase extraction column 5, or carry out parallel connection by between several constant temperature solid-phase extraction columns 5, namely the water inlet 21 of each constant temperature solid-phase extraction column 5 all directly connects water pump 9, and delivery port 22 is connected directly to water tank 92.
In the present embodiment is preferred pipe 2 sidewall on be provided with frosted layer, when taking this constant temperature solid-phase extraction column 5, the sidewall of the hand-held interior pipe 2 of staff, frosted layer then can increasing friction force, prevents its Automatic-falling.
The above is only preferred embodiment of the present utility model, protection domain of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
