The plastic decomposing device is used for decomposing plastic in the toys; the crushing device is used for crushing a plastic sample; the ultrasonic treatment device is used for vibrating and extracting the crushed sample; and the quantitative analysis instrument is used for carrying out fast plasticizer analysis on the toys. The utility model can improve the extraction efficiency of plasticizer in the detection process and effectively realize large-scale and fast detection of the plasticizer for plastic toys.
Description
Technical field
The utility model relates to a kind of toy chemical constitution pick-up unit, relates in particular to the pick-up unit of plasticiser component.
Background technology
China is the production and consumption big country of toy product, also is the leading exporter of international toy product, and 2/3rds of world's toy is produced by China, and the toy safety problem is the emphasis problem of present international toy.The technical regulation of a whole set of relevant safety, health, environmental protection has progressively been set up in order to ensure children's health in countries in the world.Since 2006, broken out a series of incidents of recalling at toy safety in the world, more than batch, quantity is big, and China's toys export has been caused ill effect.
To exceed standard be one of the maximum project of recalling at toy in the world at present to phthalate plasticizers in the plastic toys.The standard detecting method of toy plastifier generally adopts the Soxhlet extraction process to extract plastifier or quick solvent extraction extracts plastifier, but extraction time is all very long, need be as the Soxhlet extraction process at 6-16 hour, solvent extraction needs 3～4 hours fast, the solvent extraction time is very long, and extraction efficiency is not high, and the plastifier extraction not exclusively, be difficult to satisfy a large amount of and quick that toy detects, high-quality needs.
The utility model content
At the shortcoming of prior art, the purpose of this utility model provides a kind of toy chemical constitution pick-up unit that can effectively realize fast detecting in enormous quantities and improve the plastifier extraction ratio.
For achieving the above object, the technical solution of the utility model is: a kind of toy chemical constitution pick-up unit, the ultrasonic treatment unit that comprise plastic cement decomposer that the plastic cement in the toy is decomposed, the plastic cement sample is carried out broken breaker, sample after the fragmentation is shaken and extracts and will extract the quantitative test instrument that sample carries out the plastifier analysis.
This breaker comprises housing, is located at the broken blade of high rigidity in the housing and drives the high speed rotating motor system that broken blade rotates.
This breaker also comprises sample is carried out freezing refrigerating plant.
This refrigerating plant comprises liquid nitrogen source and the liquid nitrogen ascending pipe that is connected with breaker.
This ultrasonic treatment unit comprises sampling receptacle, high frequency oscillation device, energy converter and the power supply thereof of depositing sample, and wherein, sampling receptacle places on the high frequency oscillation device by medium, and energy converter drives the high frequency oscillation device by high-frequency current.
All be connected with the sample driving groove between plastic cement decomposer and the breaker and between plastic cement decomposer and the ultrasonic treatment unit.
Compared with prior art, the utility model is by the automation equipment of plastic cement decomposer, breaker and ultrasonic treatment unit, plastics in the toy are decomposed out, and it is broken into fragment, by intensified by ultrasonic wave the plastifier in the toy material is extracted again, this device can be under the prerequisite that does not change the plastic toys chemical property, effectively improve the extraction ratio of plastifier, in addition, this pick-up unit only needs one hour time from decomposing, be crushed to ultrasonic concussion, can effectively realize the fast detecting in enormous quantities of sample.

In the present embodiment, this breaker comprises housing 3, is located at the broken blade 2 of high rigidity in the housing 3 and drives the high speed rotating motor system 1 that broken blade 2 rotates.
This breaker also comprises sample carried out freezing refrigerating plant, and sample carries out low temperature brittleness earlier before carrying out fragmentation, pulverize by broken blade through the sample behind the low temperature brittleness again, can make sample form thinner more uniform powder, and size is less than 0.1mm.
In the present embodiment, this refrigerating plant comprises liquid nitrogen source 4 and the liquid nitrogen ascending pipe 5 that is connected with breaker.Sample is played and is injected 200ml～500ml liquid nitrogen in the breaker before carrying out fragmentation, makes the freezing sclerosis of toy PVC plastic cement at low temperatures.
In the present embodiment, this ultrasonic treatment unit comprises sampling receptacle 6, high frequency oscillation device 7, energy converter 8 and the power supply thereof of depositing sample, wherein, sampling receptacle 6 places on the high frequency oscillation device 7 by medium, and energy converter 8 drives high frequency oscillation device 7 by high-frequency current.
Above-mentioned sampling receptacle is a 50ml tool plug erlenmeyer flask, and above-mentioned medium is a water.For convenience of filtration, washing, collection, the constant volume of sample, sampling receptacle has also added the ethylene dichloride solvent.
All be connected with the sample driving groove between plastic cement decomposer and the breaker and between breaker and the ultrasonic treatment unit.
As shown in Figure 3, the testing process of the utility model pick-up unit may further comprise the steps:
A. receive the toy sample;
B. utilize the plastic cement decomposer that the PVC plastic cement in the toy is decomposed, and the plastic cement sample is made 50 * 50mm bulk be placed in the sample driving groove;
C. after breaker receives the plastic cement sample, inject the 200ml-500ml liquid nitrogen, make the freezing sclerosis of PVC plastic cement at low temperatures, start rotation motor, drive the broken blade of high rigidity, toy plastic cement freezing crushing is become the following powder of 0.1mm;
D. the powdered sample after pulverizing is sent to ultrasonic treatment unit by the sample driving groove, and sample is placed 50ml tool plug erlenmeyer flask, adds 25ml ethylene dichloride solvent, and the thermostatic ultrasonic concussion was extracted 30～60 minutes;
E. utilize the quantitative test instrument that the phthalate plasticizers in the sample is carried out quantitative test.
