Slag cake crusher capable of dynamically adjusting speed and control method thereof

Abstract

The invention provides a slag cake crusher capable of dynamically adjusting speed and a control method thereof. The slag cake crusher comprises a driving motor, a crushing chamber and a control system, wherein a feeding hole is formed at the upper end of the crushing chamber; a discharging hole is formed at the lower end of the crushing chamber; a crushing roller shaft is arranged inside the crushing chamber; the crushing roller shaft is connected with the driving motor through a coupler; spiral cutter teeth are welded on the surface of the crushing roller shaft; convex teeth are arranged on the inner wall of the crushing chamber; gaps are formed between the convex teeth and spiral cutter teeth; the control system comprises a power supply, a PLC (Programmable Logic Controller) controller, a man-machine interaction device, a frequency changer, a coder mounted on a shaft of the driving motor and a temperature senor mounted on the crushing roller shaft; the PLC controller comprises a speed controller and a temperature correction rotation speed controller. By improving the structure of the slag cake crusher and using a double closed-loop dynamic control adjustment method, the automatic control of crushing process and speed is achieved, the dynamic change of slag cake crushing load is automatically adapted, and the crushing force and crushing efficiency are maximized.

Description

technical field

[0001] The invention belongs to the electromechanical field, in particular to a dynamic speed-adjustable slag cake crusher and a control method thereof. Background technique

[0002] Crushing is one of the most important processes in the feed mill. The power equipment of the crusher accounts for one-third or more of the total supporting power of the feed mill, so it directly affects the production scale, energy consumption, feed processing cost and product quality of the feed mill. quality.

[0003] With the development of animal husbandry production, more and more cakes will be used as the main vegetable protein for poultry and livestock. In the northern Jiangsu, Shandong, Anhui and other places of China, the oil residue after oil extraction is usually in the shape of a cake with a diameter of 500-600mm, a thickness of 70-90mm, and a weight of about 10Kg. The common ones are bean cake, vegetable cake and peanut cake, etc. Various slag cakes, which can be u...
