Description
Technical field
The invention belongs to tobacco experimental apparatus technical field, be 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 been stipulated use sand core funnel removal interfering material and has extracted starch in the mensuration continuous flow method > > of China tobacco business standard YC/T 216-2013 < < 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; At the top of described container, be provided with upper feeding mouth 6, 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 of 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), by the double-stranded ball of described pressurization, suitably in glass container, pressurize, 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 of using 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, thereby be easy to cause clamping unstable situation, occur; And when using a plurality of 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 funnel stand of special use, improves the efficiency of operation, is prior art urgent problem.
Summary of the invention
To be solved by this invention be the clamping that exists while using iron stand clamping sand core funnel in prior art unstable, take the larger problem of experiment table top, and then provide funnel stand a kind of convenient operation, sand core funnel special use.
The technical scheme that the present invention solves the problems of the technologies described above employing is:
A kind of sand core funnel frame, comprise: support, on described support, be fixedly installed the first gripper shoe and be positioned at the second gripper shoe below described the first gripper shoe, described the first gripper shoe and the second gripper shoe are all horizontally disposed with, distance between described the first gripper shoe and the second gripper shoe is less than the cock of described sand core funnel and is positioned at the above part of cock along the length sum of vertical direction, and the distance of the described tray bottom surface of described the second gripper shoe distance is greater than described sand core funnel and is positioned at cock below part length vertically;
In described the first gripper shoe, be provided with a plurality of the first putting holes, the diameter of described the first putting hole is greater than or equal to the maximum transversal length of described sand core funnel, is suitable for described sand core funnel and vertically inserts;
In described the second gripper shoe, be provided with second putting hole identical with described the first putting hole quantity, the center of circle of described the second putting hole and described the first putting hole is corresponding one by one, the diameter of described the second putting hole is less than the cock length of described sand core funnel, is greater than the maximum transversal length that described sand core funnel is positioned at cock below part simultaneously; Described in each, described in the distance of center circle of the second putting hole, the minimum range of the second gripper shoe outer rim is less than the operating side of described cock apart from the distance of described sand core funnel axis;
The pallet that is placed on described support below, the bottom surface of described pallet and sidewall form the cavity that is suitable for receiving fluids, on described pallet, are provided with leakage fluid dram.
Described support is comprised of two rectangle side plates that are oppositely arranged, and two described side plates be arranged in parallel, and described the first gripper shoe and the second gripper shoe are between two described side plates.
Described the first gripper shoe and the second gripper shoe are rectangle.
The first putting hole in described the first gripper shoe is provided with two rows.
The diameter of described the first putting hole is than the large 2-4mm of maximum transversal length of described sand core funnel.
Described the first gripper shoe is fixedly connected with the top of two described side plates respectively.
