Description
Technical field
The utility model belongs to tobacco experimental apparatus technical field, is specifically related to a kind of for placing the support of sand core funnel.
Background technology
Sand core funnel is a kind of experimental apparatus conventional in tobacco laboratory.Two kinds of functions are got and filtered to sand core funnel treasury in one, object in being commonly used to extraction and fractionation sample has just clearly stipulated use sand core funnel removal interfering material and has extracted starch in China tobacco business standard YC/T 216-2013 " the mensuration continuous flow method of tobacco and tobacco product starch ".
In Chinese patent literature CN101082551A, disclose a kind of sand core funnel, the structure of this sand core funnel as shown in Figure 1, is the glass container that an inside is provided with glass core 5, and described glass core 5 is upper and lower two chambers by the interior separation of glass container; Be provided with upper feeding mouth 6 at the top of described container, bottom is provided with lower discharge gate 7, and under glass container, discharge gate 7 places are horizontally arranged with ground, are provided with the cock of polytetrafluoroethylene (PTFE) material in described ground, in described cock, are provided with apocenosis passage.This sand core funnel in use, cock (keeping described apocenosis passage level) described in first rotary closing, described upper feeding mouth 6 is connected with glass inflating head, again described glass inflating head is connected with the pressurization duplex ball that source of the gas is provided by pipeline, then the upper chamber that tobacco and extract is placed on to described glass container extracts, after extraction process completes, cock described in Unscrew (keeping described apocenosis passage is vertical state), suitably in glass container, pressurize by the double-stranded ball of described pressurization, extract is clamp-oned to lower chamber and discharge by lower discharge gate 7, tobacco sample is set to the top of staying described glass core 5.
Because prior art there is no the support that is exclusively used in sand core funnel, therefore when technical staff states in the use sand core funnel and operates, generally that described sand core funnel is clamped on iron stand, but the defect that uses iron stand to clamp is: owing to all needing between each extraction that described sand core funnel is cleaned, added tobacco sample or changes extractant, therefore in operating process, need repeatedly to win, clamp sand core funnel, occur thereby be easy to cause clamping unstable situation; And in the time using multiple sand core funnels to carry out batch operation, need to use a large amount of iron stands simultaneously, can cause the experiment table top that takies larger, be not easy to operation.
Along with the appearance of tobacco business standard YC/T 216-2013, the sand core funnel of said structure in industry will generally be used, and therefore how to design a kind of special funnel stand, improves the efficiency of operation, is prior art urgent problem.
Utility model content
To be solved in the utility model be the clamping shakiness that exists while using iron stand clamping sand core funnel in prior art, take the larger problem of experiment table top, and then provide funnel stand a kind of convenient operation, that sand core funnel is special.
The technical scheme in the invention for solving the above technical problem is:
