A solid material filtrate feeding structure

Abstract

The invention provides a feeding structure of solid material filtrate. The feeding structure comprises a dried material storage box, a wet material storage box, a filtering plate and a reaction box, the reaction box comprises an isolated feeding part arranged at the upper part and a reaction tank body part arranged at the lower part, the isolated feeding part is separated into a dried feeding areaand a wet feeding area, the filtering plate is arranged in the wet feeding area, the filtering plate comprises a plate body, a filtering net is arranged on the plate body, a drainage tube is arrangedat the lower portion of the filtering net, the plate body is connected with a rotary motor, and a filtering net vibrator is arranged on the filtering net. The feeding structure has the advantages ofoperational safety of the reaction of dangerous materials.

Description

technical field [0001] The invention relates to the technical field of teaching instruments, in particular to a solid substance filtrate blanking structure. Background technique [0002] In the chemistry teaching of junior high school and high school, a large number of student experiments will be used to improve students' understanding of chemical reactions. Compared with physical experiments and computer experiments, chemical experiments will use highly oxidizing, highly corrosive, and highly active substances. Experiments, such substances may cause harm if they accidentally contact human skin during operation. At the same time, such substances may produce toxic gases, irritating gases and other substances during the reaction process, and active substances such as cesium and potassium are reacting. During the process, high heat will also be generated, and the reaction process is too intense, accompanied by boiling and sputtering of the reaction liquid. Students who do not ...

Problems solved by technology

[0002] In the chemistry teaching of junior high school and high school, a large number of student experiments will be used to improve students' understanding of chemical reactions. Compared with physical experiments and computer experiments, chemical experiments will use highly oxidizing, highly corrosive, and highly active substances. Experiments, such substances may cause harm if they accidentally touch human skin during operation. At the same time, such substances may produce toxic gases, irritating gases and other substances during the reaction process, and active substances such as cesium and potassium react High heat will also be generated during the process, and the reaction process is too intense, accompanied by problems such as boiling and sputtering of the reaction solution. If quantitative, timing, and fixed-flow operations are not carried out in accordance with the specifications, accidents are prone to occur. For example, potassium that should be stored in kerosene is destroyed. Accidents such as violent reactions caused by unruly students throwing into the pool and burning the classmates at the neighboring table, while the existing teaching laboratories still use general-purpose open experimental equipment such as beakers and flasks for experiments, are more likely to cause accidents, so some teachers In order to prevent risks in the experiment, part of the experiment can only be abandoned, which makes students have no concrete understanding of the reaction process of the highly oxidizing, highly corrosive, and highly active substances in the books, which reduces the quality of teaching
