An automatic detection device for the sieve of a pulverizer

Abstract

The invention discloses an automatic detecting device of a pulverizer sieving piece. The automatic detecting device comprises a sieving device for sieving materials. The sieving device is disposed at the discharge outlet of a pulverizer. The sieving device comprises a screen. The pore size of the screen is identical with that of a pulverizer sieving piece. Large-particle materials are retained on the screen. The horizontal plane of the screen has a certain included angle. A discharge outlet is formed at the lowest point of the screen. An impurity accumulating barrel for receiving materials is disposed at the discharge outlet. A sensor is disposed at the bottom of the impurity accumulating barrel. The automatic detecting device has the advantages that pulverized materials enter the sieving device, the unpulverized large-particle materials are retained on the upper side of the screen, downwardly flow towards the discharge outlet under gravity and the vibration action of the screen, and enter the impurity accumulating barrel, the sensor gives out an alarm when detecting the materials in the impurity accumulating barrel, damage of the sieving piece of the pulverizer can be noticed, the damaged sieving piece can be timely repaired, and convenience and foundation are provided for automatic production.

Description

technical field [0001] The patent of the present invention relates to a breakage detection technology of a sieve of a pulverizer, in particular to an automatic detection device for a sieve of a pulverizer. Background technique [0002] The pulverizer is one of the most important equipment in the feed production process. The consistency of the fineness of the crushed material directly determines the quality of the feed and the breeding effect. Raw grain grains account for the vast majority of the livestock and poultry feed formula, and the proportion generally reaches or exceeds 60%. The main task of the grinder for livestock and poultry feed is to crush the raw grain grains, and the quality of the crushing determines the quality of the feed. At present, the grain raw grains that are crushed by the grinder are of poor quality due to conditions such as storage and storage, and usually contain some stones, iron impurities, etc. The cleaning products configured by the front-end ...

AI Technical Summary

Problems solved by technology

[0003] 1. At present, feed engineering generally does not have a breakage detection device for the sieve of the pulverizer. Feed factories generally use manual sampling at the top of the batching warehouse to see if there are large particles in the material to determine whether the sieve of the pulverizer is damaged. When the particles are large, the materials in the batching bin have been polluted, and the amount of pollutants cannot be judged, resulting in the failure of the whole bin to be used normally

[0004] 2. Use manual sampling on the top of the batching warehouse to observe the breakage of the grinder screen. Due to the long time interval, it usually reaches or even exceeds half an hour, so the system cannot respond quickly, and at the same time it cannot meet the requirements of automatic control of feed production engineering.
