Novel feedstuff pulverizer

Abstract

The invention discloses a feed pulverizer, which comprises a stander connected with a pulverizing chamber and a driving force system, wherein the pulverizing chamber comprises a shell through which a pulverizing main shaft passes; two ends of a pulverizing main shaft in the shell are connected with two end plates; the pulverizing main shaft between the two end plates is connected with a spacer; and a pulverizing device is connected between the two end plates, and a sieve-pressing mechanism is arranged in the pulverizing chamber. The pulverizer is characterized in that a flexible coupling shaft device is connected between a main shaft in the driving force system and the pulverizing main shaft in a pulverizing plate mechanism; the internal surface of a sieve piece in the pulverizing chamber is provided with convex points of a pulverizing flow passage; the end plate of the shell is provided with an air inlet hole; the end plate on the pulverizing main shaft is provided with an air inlet hole; the end plate of the spacer is provided with an air inlet hole; and an outer ring of the spacer is provided with air outlet holes along the circumference. The designed pulverizer adopts a flexible connection transmission mode, a combined sieve-pressing structure, and full radial inlet air; a plurality of the convex points are additionally arranged inside the pulverizing chamber, and the pulverizing chamber is divided into a plurality of cavities; meanwhile, the sieve piece is changed into a plurality of small pieces. The pulverizer has the advantages of simple and reliable system structure, convenient manufacture and installation, reliable operation, convenient use, stable operation quality, satisfaction to the requirements of different types of pulverizers and improved yield to achieve the technique of energy conservation and consumption reduction.

Description

technical field [0001] The invention belongs to feed processing equipment, in particular to a feed grinder. Background technique [0002] At present, the transmission of the pulverizer adopts the form of rigid connection between the motor and the pulverizing main shaft. Because the speed of the pulverizer main shaft is high, the diameter is large, and the power of the motor is large. During the process of the motor from stationary to rotating to the rated speed, it is relatively difficult to start the motor. Difficult, it is often started by artificially increasing the power of the motor. Due to the rotational inertia, after reaching the rated speed, the power of the motor has a surplus, causing the motor to work under low load for a long time, wasting a lot of electric energy and increasing the feed mill. In addition, the motor is also very easy to be damaged under the condition of high-load start-up and low-load operation for a long time. Therefore, it is necessary to im...

Problems solved by technology

[0005]At present, the pulverizer generally adopts the whole board as the sieve plate, and the whole pulverizer is composed of two such sieve plates. More frequently, as long as there is a perforation in the entire sieve plate, it must be replaced, resulting in an increase in the cost of each feed manufacturer, and no better way has been found

A lot of frits were wasted
