AI Technical Summary

Technical Problem

In the existing technology, solid urea particles cannot be effectively crushed and screened during the production process of automotive urea, resulting in larger particles not being able to fuse quickly, which affects urea quality and production efficiency.

Method used

A fully automatic filtration device was designed, comprising a crushing mechanism and a screening mechanism. The crushing motor drives the crushing roller to crush large urea particles, and the screening cone plate and the bonding plate work together to screen and agitate the solid urea particles, preventing clogging and improving dissolution efficiency.

Benefits of technology

This effectively avoids the impact of large solid urea particles on dissolution efficiency, improving the efficiency and quality of automotive urea production.

Abstract

This utility model relates to the field of filtration device technology and discloses a fully automatic filtration device for automotive urea production. It includes a mixing tank, with a pulverizing mechanism at the upper end of the mixing tank. The pulverizing mechanism includes a pulverizing frame fixedly connected to the upper surface of the mixing tank, a pulverizing groove on the upper surface of the pulverizing frame, and a pulverizing motor fixedly connected to one outer wall of the pulverizing frame. The output end of the pulverizing motor extends into the interior of the pulverizing groove and is fixedly connected to a first pulverizing roller. In this utility model, solid urea is pulverized and falls into the upper end of a screening cone plate. The solid urea particles are then screened and filtered through the aperture of the screening cone plate. Simultaneously, a bonding plate agitates the falling solid urea particles, effectively preventing clogging of the screening cone plate apertures. This screening mechanism effectively avoids the problem of large solid urea particles falling into the mixing tank and affecting the dissolution efficiency.
