Description

Technical Field

[0001] The utility model relates to the technical field of sampling devices, in particular to a sampling device for a carbon preheating pot. Background Art

[0002] In the process of carbon production, in order to control the production accuracy and ensure the product quality, the materials are usually sampled in the batching and subsequent links to check whether the content of each component in the batched materials is qualified. The sampling objects are usually the materials in the preheating mixing pot or the kneading pot. The main reason is that the materials in these two links have been prepared and stirred evenly, so they can be directly sampled, which is simple to sample and has a good inspection effect.

[0003] At present, the tool used for carbon sampling is a sampling spoon. When sampling, it is necessary to avoid the working parts in the preheating stirring pot or the kneading pot. In many cases, the sampling must be stopped, which is not easy to operate and affects production efficiency. There is an urgent need for a fast sampling device that is easy to operate and does not require shutdown. Utility Model Content

[0004] The utility model aims to provide a sampling device for a carbon preheating pot, so as to solve the problem that the working parts of the preheating stirring pot need to be avoided during sampling, and the sampling is often stopped, which is difficult to operate and affects production efficiency.

[0007] A further technical solution is that the plug is composed of a ball head and a cone head.

[0008] A further technical solution is: the plug is located between the feed end of the feed pipe and the discharge end of the preheating pot.

[0009] A further technical solution is that a material receiving frame is arranged below the discharge end of the screw conveyor.

[0010] A further technical solution is: a feed bin with a gate valve is provided on the screw conveyor.

[0011] A further technical solution is that the feed end of the screw conveyor is located between the plug and the valve.

The feed end of the screw conveyor 6 is located between the plug 4 and the valve 5.

[0025] Preferably, the plug 4 is composed of a ball head 41 and a cone head 42. The plug 4 is located between the feed end of the feed tube 3 and the discharge end of the preheating pot 1.

[0026] The ball head 41 serves to block the discharge pipe 3, and the conical head 42 can adjust the material flow rate by changing the diameter of the discharge pipe 3 as the rotation angle changes, and can also use its sharp nature to break the arch of the material at the discharge end of the preheating pot 1.
