Frangible grenade

Abstract

The invention relates to a frangible grenade. The frangible grenade comprises a glass conical bottle and a sealing bottle plug installed on a bottle opening of the glass conical bottle, an air inlet assembly, an ignition assembly, an exhaust assembly and a mounting rod are inserted into the sealing bottle plug, and the lower end of the mounting rod is provided with a sample accommodating assembly;the air inlet assembly comprises an air inlet pipe and a blowing head arranged at the lower end of the air inlet pipe; the exhaust assembly comprises an exhaust pipe and a filter sand head, wherein the filter sand head is arranged at the lower end of the exhaust pipe; and a one-way valve and a manual adjusting valve are arranged on the exhaust pipe, and the ignition assembly is an ignition deviceor a heater. According to the frangible grenade, the sample bearing capacity, the reaction time and the combustion condition can be controlled according to experiments, so that the experiment continuity and the expansibility are achieved, the device cost is low, the operation is simple and convenient, the application range is wide, and the use safety is improved.

Description

technical field [0001] The invention belongs to the technical field of laboratory instruments, in particular to a combustion bottle. Background technique [0002] The combustion test is used to evaluate the composition or combustion performance of the sample by combustion, such as: oxygen bottle combustion, flame color test, combustion test and other experiments. Organic substances such as sulfur or other elements are burned in an oxygen-filled combustion bottle. After the combustion products are absorbed into the absorbing liquid, suitable analytical methods are used to check or measure the content of halogen or sulfur and other elements. The flame color test refers to the reaction of certain metals or their compounds to the characteristic color of the flame when burned in a flame. The sample is usually in the form of a liquid, powder or small pieces, and is contained in a clean and less reactive metal utensil. The sample is burnt in a flame. In chemistry, it is often use...

AI Technical Summary

Problems solved by technology

[0004] 1). In terms of gas replacement: in conventional experiments, only a single gas can be introduced, the gas replacement is not complete, and it cannot be sealed in time after the replacement. The flow rate is not easy to control, causing the absorption liquid to splash and other shortcomings

[0005] 2). Sample fixing: In routine experiments, it is often difficult to fix the sample on the platinum wire, the sample bag is easy to fall, the sample is not easy to ignite, the sample load capacity is small, the reaction time is short and it is difficult to observe, the position of the flame is not uniform, the sample and Insufficient combustion of the wrapped substance. During the burning process of the sample, due to the burning and damage of the wrapped substance, the sample powder, liquid droplets, and wrapped substance fell into the absorption liquid, which affected the experimental results. , affecting the experimental results and other shortcomings

[0006] 3). Platinum wire: in routine experiments, the connection with the bottom of the bottle stopper is often not firm, and it is easy to drop during operation, especially during shock absorption, and it will be deformed by burning and heating, causing the sample and packaged substances to fall or sag and contact the absorption liquid. Platinum wire is easy to deform and fuse, etc.

[0007] 4). Other aspects: In routine experiments, there are often experimental failures caused by the early extinguishment of the flame during the experiment; during the combustion process, the bottle body burst due to the uncontrollable flame position, resulting in experiment failure and even personal injury; combustion and gas After absorbing the negative pressure in the bottle, it cannot be opened, and even broken when opened, causing personal injury and other shortcomings

[0008] In addition, auxiliary observation glass sheets are often used to observe the experimental results during the experiment, but there are disadvantages such as the observation angle of the auxiliary observation glass sheets is not uniform, which affects the observation of the experimental results.
