Abstract
The utility model relates to a device for making an assay specimen, which is mainly used in a product assay process for the acetic acid extract of microcrystalline puffing for straw tableware. The device for making an assay specimen comprises an oven, and is characterized in that a glass dish is arranged in the oven; a drip tube with a control valve is arranged on the upper part of the glass dish; a transparent drip cup is connected to the upper end of the drip tube; and a vacuum tube connected with a vacuum pump, and an intake tube are arranged at the upper end of the drip cup. The device for making an assay specimen disclosed by the utility model has the beneficial effects that materials are large in heating area and uniform in roasting by being automatically dripped into the glass surface dish in the oven regularly and quantitatively by using the device, temperature control is balanced, and volatile matters are evaporated thoroughly, thus ensuring the accuracy of product detection indexes, and shortening inspection time.
Description
Technical field
The utility model relates to a kind of device of making assay specimen, mainly is used in the product procedure of crystallite puffing straw tableware acetic acid extract.
Background technology
When producing disposable tableware, when particularly being raw material with degradable stalk fibre, the acetic acid extract is one of important laboratory indexes in the production run, the acetic acid extract needs the leachate of 200g when chemical examination, people normally are placed directly in liquid in the container now, then put in the baking box roasting, in container, distribute very thick because of liquid during whole heating, not only required stoving time is longer, and when baking heating surface area less, evaporation is uneven, and the volatile matter evaporation is thorough, thereby affects the accuracy that product detects index.
Summary of the invention
For the problems referred to above, the utility model provides a kind of device that can make liquid evaporation make uniformly assay specimen.
The utility model is achieved by the following technical solution:
A kind of device of making assay specimen, comprise baking box, it is characterized in that: be provided with a glass dish in the described baking box, glass dish top is established one with the dropper of operation valve, and the upper end of dropper is connected with the transparent cup that drips, and the upper end of dripping cup arranges a vacuum tube that links to each other with vacuum pump and a draft tube.
The device of making assay specimen of the present utility model, that a glass dish is set in baking box, glass dish top is established one with the dropper of operation valve, liquid drips, the upper end of dropper is connected with the transparent cup that drips, drip cup and be used for contain fluid, the upper end of dripping cup arranges a vacuum tube that links to each other with vacuum pump and a draft tube, be used for inside the control air pressure so that can be smoothly drop of liquid outward.
The beneficial effect that the utility model is made the device of assay specimen is: in the glass surface ware of the device of use assay specimen automatic dripping at regular time and quantity in the baking oven, thereby it is large to reach the material heating surface area, baking evenly, temperature control balance, the volatile matter evaporation thoroughly, thereby guaranteed that product detects the accuracy of index, has shortened proving time.
Description of drawings
Fig. 1 is the front view of structure of the present utility model;
Among the figure: 1, baking box, 2, glass dish, 3, dropper, 4, drip cup, 5, draft tube, 6, vacuum tube, 7, vacuum pump.
Embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment comprises baking box 1, it is characterized in that: be provided with a glass dish 2 in the described baking box 1, glass dish 2 tops are established one with the dropper 3 of operation valve, the upper end of dropper 3 is connected with a transparent cup 4, and the upper end of dripping cup 4 arranges a vacuum tube 6 that links to each other with vacuum pump 7 and a draft tube 5.
When using this device, crystallite puffing straw tableware acetic acid extract is contained in first in the cup 4, can add this crystallite puffing straw tableware acetic acid extract by draft tube 5, should close the operation valve on the dropper this moment, under the effect of vacuum pump 7, the air pressure that drips in the cup 4 is diminished, under the effect of ambient atmosphere, liquid is inhaled into and drips in the cup 4, also can adopt and else hold mode, holds the operation valve of opening afterwards on the dropper 3, liquid can be splashed in the glass dish 2 in the baking box 1, in order to control the speed of liquid, can change the thickness of dropper or the air pressure of control vacuum pump 7, thereby quantitatively drip when formation is anticipated, material forms film-form after dropping on vessel, therefore the volatile matter of oven dry is more thorough, has reduced the solid accumulation volume large, the shortcoming that heat dissipation can be high.
