Description

Technical Field

[0001] The utility model relates to the technical field of chemical engineering, in particular to a pre-mixing device for a chemical engineering reactor. Background Art

[0002] The broad understanding of chemical engineering reactors is a container for physical or chemical reactions. Through the structural design and parameter configuration of the container, the heating, evaporation, cooling and other changes required by the process are realized. Reactors are widely used in the fields of petroleum, chemical, rubber, pesticide, dye, medicine, food, etc. For materials that need to undergo chemical reactions, mixing is a crucial step. Therefore, in order to facilitate subsequent reaction processes, producers will use a mixing device to fully mix the materials in advance.

[0003] The patent document with the prior art publication number CN217594475U provides a pre-mixing device for a chemical engineering reactor, including a bottom plate, a reactor body and a device box, the upper part between the two sides of the inner cavity of the device box is fixedly connected with a mixing frame through a fixing plate, and the bottom of the mixing frame is fixedly connected with a stirring drum through an opening. The utility model relates to the field of chemical engineering technology. The pre-mixing device for the chemical engineering reactor uses multiple feed pipes to connect to the mixing frame, allowing a small amount of liquid to be transported, and then flows into the stirring drum through a mesh plate. The stirring blades driven by the motor fully mix the liquid, and then the liquid is extracted and sprayed out in a mist form under the action of a water pump. This setting allows a variety of liquid raw materials to flow directly into the reactor, and they can be fully mixed during the flow process, reducing the time for sealed mixing.

[0004] However, the existing pre-mixing device of the reactor cannot crush and filter the relatively large solid particles of chemical materials, resulting in insufficient pre-mixing, which will affect the reaction efficiency of the reactor, resulting in reduced utilization of chemical materials, low mixing uniformity of various components in the chemical materials, and poor quality of the chemical materials after reaction. For this reason, we propose a pre-mixing device for a chemical engineering reactor. Utility Model Content

[0016] (1) A pre-mixing device for a chemical engineering reactor, wherein a crushing wheel and a filter are provided. When chemical materials need to be pre-mixed, the materials to be mixed are poured into the feed port on the top of the crushing machine body. At this time, the first motor and the second motor drive the crushing wheel to rotate respectively. The driving direction of the first motor is counterclockwise, while the driving direction of the second motor is clockwise. The materials passing through are squeezed and crushed by the two crushing wheels with different rotation directions, so that larger chemical particles are crushed into smaller chemical particles. The crushed chemical particles are filtered by the filter. The larger chemical particles are intercepted on the filter. When a certain amount of chemical particles is reached, the filter is pulled out, and the larger chemical particles on the filter are poured back into the feed port to be crushed and filtered again until the chemical materials are crushed into particles that can pass through the filter. The smaller chemical particles fall from the filter into the stirring tank for stirring and mixing. The crushed chemical materials form particles of uniform size, which makes the stirring and mixing more sufficient, thereby indirectly improving the reaction efficiency of the reactor and the quality of the chemical products after the reaction.
