AI Technical Summary

Technical Problem

In existing urea production equipment, eddies cause uneven urea concentration inside the solution, and urea granules cannot be evenly covered when added, reducing mixing efficiency.

Method used

The inner cylinder is divided into an inner mixing chamber and an outer mixing chamber. The flow limiting mechanism and the turbulence mechanism, together with the floating plate and the flow guide plate, are used to drive the floating plate to float up and down and tilt and jump through the vortex rotation, which enhances the mixing effect. The raw material feed rate and sorting are controlled by the filter plate to achieve precise mixing.

Benefits of technology

It improves the degree of mixing of the solution in the horizontal direction, breaks down local concentration differences, achieves a more uniform mixing state, prevents clumping, and improves mixing efficiency.

Abstract

The invention relates to the technical field of urea production, in particular to a urea production device. Comprising a mixing tank, a feeding hopper, a stirring device, a liquid inlet pipe and a liquid discharging pipe, an inner cylinder is arranged in the mixing tank and divides the mixing tank into an inner mixing bin for storing premixed liquid and an outer mixing bin for storing raw materials to be mixed from inside to outside, a filter screen plate is arranged above the inner cylinder, and small-particle raw materials are evenly dispersed in the inner mixing bin through the filter screen plate; and the large-particle raw materials are guided into the external mixing bin. In the liquid separation stage, water waves generated by vortex rotation are used for driving the floating plate to drive the drainage plate to float up and down in the premixed liquid, so that vortex outer ring solutions with different depths are guided to the axis, and the mixing degree of the solutions in the horizontal direction is enhanced; the floating plate is used for raising the vortex outer ring solution in an inclined manner, so that gravitational potential energy is used for impacting the rear part of the drainage plate, the local concentration difference is further broken, and the solution is promoted to reach a more uniform mixing state.
