Electric-screw-rod-type clearance adjustment crushing machine and control method thereof

Abstract

The invention discloses an electric-screw-rod-type clearance adjustment crushing machine and a control method thereof, and belongs to the field of furnace slag treatment. The electric-screw-rod-type clearance adjustment crushing machine comprises a slag bucket, a crushing machine body, a jaw plate, a connection screw rod, a roller shaft and a crushing outlet, and also comprises an electric screw rod, a screw rod jacking bracket, a control box, a jamming inductor and an electric control cabinet, wherein the electric screw rod is arranged at the left lower corner outside the crushing machine body in a tilting manner; the upper top surface of the electric screw rod jacking bracket is in contact with the rear surface of the jaw plate; the electric screw rod is connected with the electric control cabinet through the control box; the upper end of the jaw plate is hinged to the crushing machine body through the connection screw rod; the jamming inductor is arranged on the roller shaft; a roller shaft motor is connected with the electric control cabinet; a PLC (programmable logic controller) control chip is arranged in the electric control cabinet. The electric-screw-rod-type clearance adjustment crushing machine has the advantages that the electric control cabinet realizes automatic control, and labor is saved; due to clearance adjustment by the electric screw rod, the response speed is high, the clearance adjustment is accurate, and the supporting force is high; the electric-screw-rod-type clearance adjustment crushing machine is safe and reliable and has a dual locking prevention function and the like.

Description

technical field [0001] The invention relates to an electric lead screw type crusher for adjusting gaps and a control method thereof, belonging to the field of slag treatment. Background technique [0002] Generally speaking, there are two major problems in pneumatic slag conveying: one is that the pipeline is blocked, and the other is that the increase in the conveying speed due to the large particle size of the slag will lead to rapid wear and tear of the pipeline, which will cause frequent blockage of subsequent pneumatic conveying pipelines and seriously affect the production safety of the power plant and lead to reduced equipment life. [0003] The existing DGS-830 single-roller crusher has been put into use for many years. Its characteristics are: the toothed roller is integrally cast, which can improve the feeding capacity of large slag blocks; the jaw plate is adjustable, and the crushing particle size is not greater than 30mm; , good sealing; the bearing seat is spl...

AI Technical Summary

Problems solved by technology

However, because the coal is often mixed with small debris such as metal iron with high hardness, these debris will be mixed into the furnace and fall into the crusher if they are not cleaned by the equipment of the coal conveying system, causing the slag extractor to be stuck, resulting in forced Furnace shutdown and fire inspection

Due to the frequent failure rate, a crusher has an average of 1-2 failures per week, which puts a lot of pressure on production.
