Description

TECHNICAL FIELD

[0001] The present application relates to the field of analytical detection instruments, in particular to a dismounting auxiliary device for a thermal gravimetric analysis system. BACKGROUND

[0002] Synchronous thermal analysis instrument has been widely used in the analysis of various organic or inorganic materials and products, covering the fields of research and development and quality control. However, in many cases, only by measuring the quality and enthalpy change of the material through thermal analysis means cannot fully identify the substance. In order to further explore the properties, structure and composition of the material, it is necessary to analyze the specific component information of the volatile products generated by the chemical reaction, thermal induced phase change, evaporation and decomposition of the material.

[0003] Mass spectrometry is a common method for gas analysis, the basic principle of which is to ionize the measured substance by electron bombardment or other means to form ions of various mass-to-charge ratios, then separate and measure the intensity of various ions according to different mass-to-charge ratios by using electromagnetic principles, so as to determine the molecular weight and structure of the measured substance, which has the advantages of fast detection rate, high resolution and sensitivity, and can detect contents as low as nanogram level.

[0004] REFERENCE Figure 1 By means of thermal mass spectrometry, a thermal mass spectrometer is prepared, which comprises a synchronous thermal analyzer 1, a connecting pipe 3 and a mass spectrometer 2. The synchronous thermal analyzer 1 comprises a main machine 11 and a furnace body 12. The diameter of the furnace body 12 is 15 cm. A plurality of heat dissipation holes 121 are formed in the top surface of the furnace body 12. The heat dissipation holes 121 are distributed in a ring shape, and the distribution width of the heat dissipation holes 121 is 6 cm. One end of the connecting pipe 3 is fixedly connected with a connecting plate 31, and the connecting plate 31 is used to connect the connecting pipe 3 with the synchronous thermal analyzer 1. The connecting pipe 3 is used to guide the generated escaping gas in the synchronous thermal analyzer 1 into the mass spectrometer 2, so as to track the generation process and concentration change of gaseous products in real time, and identify and quantitatively analyze the escaping gas. In laboratory use, there are usually two methods, one is to directly use the above-mentioned thermal mass spectrometer, and the other is to use the synchronous thermal analyzer 1 alone.

[0005] According to the related technology in the above, the inventor believes that when the synchronous thermal analyzer is used alone, the connecting pipe of the thermal mass spectrometer needs to be dismounted. In the process of dismounting, the nut connected with the connecting plate and the synchronous thermal analyzer is easy to fall into the synchronous thermal analyzer through the heat dissipation hole, and it is difficult to take out. If it is not taken out in time, it will cause great deviation to the detection result of the synchronous thermal analyzer. CONTENT OF THE INVENTION

[0010] Optionally, a receiving pocket is connected to the outer ring side of the blocking ring.

[0011] By adopting the above technical scheme, the setting of the receiving pocket can make the nuts falling on the blocking ring smoothly slide into the receiving pocket when the connecting pipe is dismounted or mounted, so that the workers can conveniently take the nuts again.

[0012] Optionally, the longitudinal section of the receiving pocket is in a U shape.

[0013] By adopting the above technical scheme, the inner surface of the receiving pocket in the U shape is smooth, the nuts will not collide and fly out when sliding, and all the sliding nuts will finally be located at the bottom of the receiving pocket, so that the workers can conveniently take out the nuts again, and the workers will not collide with hands when taking out the nuts.

[0014] Optionally, the blocking ring and the receiving pocket are made of deformable materials.

[0016] Optionally, a friction strip is fixedly connected to the surface of the receiving pocket.

[0017] By adopting the above technical scheme, the setting of the friction strip makes the nuts falling into the receiving pocket difficult to roll, so that the workers can conveniently take out the nuts again to dismount or mount the connecting pipe.

[0018] Optionally, an inclined plate is fixedly connected to one end of the top surface of the receiving pocket, and the inclined plate is inclined downward away from the mounting port.

[0019] By adopting the technical scheme, the screw cap falling into the installation port position will not fall out of the installation port, will not be clamped in the installation port, and will slide into the receiving pocket along the inclined plate, facilitating the staff to take it.

[0020] Optionally, the inclined plate is provided with two, and the two inclined plates are symmetrically arranged about the installation port.

[0021] By adopting the technical scheme, the two symmetrically arranged inclined plates can completely block the installation port, so that the screw cap will not fall out of the installation port, will not be clamped in the installation port, and will slide into the receiving pocket along the inclined plate, facilitating the staff to take it.

[0022] Optionally, one end of the blocking ring is inclined, and the other end is also inclined, and the inclined directions are opposite.

[0023] By adopting the technical scheme, the inclined design of one end of the blocking ring can effectively block the screw cap from falling off even if the installation port is too large due to long use time, so as to ensure that the screw cap does not fall outside the thermal gravimetric analysis system dismounting auxiliary device.
