Sampling extraction device suitable for chemical raw materials

Abstract

The invention discloses a sampling extraction device suitable for chemical raw materials. The sampling extraction device comprises a chemical raw material storage mechanism, a chemical raw material conveying mechanism and a chemical raw material extracting mechanism. A right side of the front surface of the chemical raw material storage mechanism is fixedly connected with the chemical raw materialconveying mechanism, and the right side of the front surface of the chemical raw material conveying mechanism is movably connected with the chemical raw material extracting mechanism. According to the sampling extraction device suitable for the chemical raw materials, a square barrel is welded to the center of the top end of the chemical raw material storage mechanism, the square barrel protrudes, a barrel loaded and transported from the outside can be effectively in butt joint with the square barrel, and the problem of leakage is prevented. A first sampling layer, a second sampling layer, athird sampling layer and a fourth sampling layer are arranged on the inner side of the chemical raw material storage mechanism so that the chemical raw materials at different levels can be sampled andextracted. Filtering plates are fixedly mounted at the intersection positions of the first sampling layer, the second sampling layer, the third sampling layer and the fourth sampling layer, and through holes formed in the surfaces of the filtering plates can prevent the problem of clogging caused by accumulation of sediments in the chemical raw materials.

Description

technical field [0001] The invention relates to the technical field of sampling extraction devices, in particular to a sampling extraction device suitable for chemical raw materials. Background technique [0002] There are many kinds of chemical raw materials and their uses are very wide. Chemical raw materials can generally be divided into two categories: organic chemical raw materials and inorganic chemical raw materials. The main raw materials of inorganic chemical products are chemical minerals containing sulfur, sodium, phosphorus, potassium, calcium, etc., coal, petroleum , natural gas, air, water, etc. In addition, the by-products and wastes of many industrial sectors are also raw materials for inorganic chemicals, for example: the coke oven gas in the coking production process in the iron and steel industry, the ammonia contained in it can be recovered by sulfuric acid to make sulfuric acid Ammonium, sulfur dioxide in the smelting waste gas of chalcopyrite, galena an...

Problems solved by technology

[0003] At present, in the production process of chemical raw materials, it is necessary to use sampling extraction devices for sampling and testing. Traditional sampling and extraction devices still have the following problems. In chemical raw materials at different depths, the precipitated substances are different, and different chemical raw materials are collected. Sampling and extraction, and in the extraction process, manual operations are required to collect chemical raw materials, which is easy to cause waste of chemical raw materials
