Reciprocating type high-temperature synthesizing device

Abstract

The present invention discloses a reciprocating high temperature synthesizer. A workbench is provided on the left and the right steel frames, guideways are provided on the workbench, the mill furnace can move from left to right repeatedly on the guideways, a support rack of the furnace tube is provided respectively on two ends of the workbench, a detachable reaction tube is respectively arranged in the two furnace tubes with the same structure, the outside outlet of each furnace tube has sealed flange respectively, water-cooling jackets are welded outside the furnace tubes near to the sealingends, a vacuum pipeline is arranged in the workbench, each end of which communicates respectively with a furnace tube corresponding by a valve, each of the furnace tubes has a vacuum manometer respectively, the vacuum pipeline communicates the atmosphere control system, the temperature control system connects with the thermocouple in the mill furnace. Employing the water-cooling jacket protects the furnace tube sealing rings, prolongs the service life and reduces the replacing frequency; synthesizing in vacuum or protection atmosphere ensures the quality of the production; reciprocating design of the furnace body realizes the quasi-continuous synthesis process and enhances the synthesis efficiency.

Description

Technical field [0001] The invention relates to compound synthesis equipment, in particular to a reciprocating high-temperature solid-phase synthesis device. Background technique [0002] High temperature synthesis furnace is one of the most commonly used equipment for synthesizing solid materials, especially powdered materials. However, the general high-temperature synthesis furnace has the following shortcomings: [0003] 1. No special protection measures are taken for the rubber sealing ring at the outlet end of the furnace tube. The sealing ring is easily aging due to the influence of the furnace temperature and needs to be replaced frequently. [0004] 2. There is no function of vacuuming or passing protective atmosphere, or both, synthesis under the state of not isolated from air will partially oxidize the raw materials and affect the purity of the product. [0005] 3. The synthesis process is carried out intermittently, that is, after the completion of one synthesis, the steps...

AI Technical Summary

Problems solved by technology

[0003] 1. No special protection measures are taken for the rubber sealing ring at the outlet end of the furnace tube. The sealing ring is easily aged due to the influence of furnace temperature and needs to be replaced frequently

[0004] 2. Without the function of vacuuming or passing through the protective atmosphere, or both, the synthesis will partially oxidize the raw materials and affect the purity of the product if the synthesis is carried out without air isolation

[0005] 3. The synthesis process is carried out intermittently, that is, after completing a synthesis, it is necessary to complete the steps of taking out the product and reloading the material before proceeding to the next synthesis. During this period, a large heat loss is caused, which affects the synthesis efficiency
