Abstract

The invention discloses a kind of charging control methods of single-shaft crusher for RDF production line, according to the operating current of single-shaft crusher main shaft, judge whether crusher stops operating, feeds push plate and whether act, control charging number and whether stop feeding.After the method for the present invention, it can solve the problem of causing material to be stuck in feed inlet due to charging is few, realize the automatic control of charging.

Description

A kind of charging control method of the single-shaft crusher for RDF production line
Technical field
The present invention relates to charging technical field of control method, specially a kind of single-shaft crusher for RDF production line Feed control method.
Background technique
For common single-shaft crusher during the work time it is possible that inlet amount is very few, material is stuck in feed hopper nearby not Can be broken, only when build up of material to it is a certain amount of when realize and fall by the gravity of material itself, be just able to achieve subsequent broken Broken process.China Patent No. 201010257995.1 discloses a kind of a kind of " method and control for automatically controlling feed of crusher Device " is its working principle is that pass through the load realization of detection crusher, when motor of crusher electric current is greater than preset value, control is filled It sets and shuts off vibrating motor supply current, mitigate the load of crusher;When motor of crusher current reduction to predetermined value, control The current supply circuit that device connects vibrating motor again after delay improves production effect, but this method is only broken to realizing Machine load is adjusted, and not can solve the control of inlet amount.
Summary of the invention
To solve the above-mentioned problems, the purpose of the present invention is to provide a kind of single-shaft crushers for RDF production line Feed control method, the single-shaft crusher inlet amount of RDF production line number be to be controlled by the electric current of crusher axis; The following steps are included:
S1, when crusher operating current is no-load current, crusher is sounded an alarm and is stopped operating;
S2, when crusher operating current be less than material fully rely on self gravity fall when main shaft work electric current and be greater than zero load When electric current, push plate on hopper inclined-plane starts to work;
S3, when crusher operating current be greater than crusher material fully rely on self gravity fall when main shaft operating current and The operating current of material gravity three times, lasting to feed when material less than crusher falls by self gravity;
S4, when the material that crusher operating current is greater than crusher falls by self gravity, the work of material gravity three times is electric Stream and the material for being less than crusher rely on the operating current of five times of self gravity falling material gravity, slow down charging rate;
S5, when crusher operating current be greater than crusher material by self gravity fall when five times of material gravity work electricity Stream stops charging.
As a further improvement of the above technical scheme:
Hydraulic control is leaned in push plate on hopper inclined-plane.
The thrust of push plate is equal to the gravity that material fully relies on self gravity falling material.
When material is stuck in feed inlet and is not enough to fall by self gravity, electric current when crusher works is less than broken Broken machine fully relies on the electric current of main shaft work when self gravity falls and electric current when being greater than crusher zero load, hydraulic thrust in material Plate starts to act, and it is 20s that the stroke action time is pushed when start-up operation, and upward stroke movement is 14s;Subsequently into being circulated throughout Journey, push plate down stroke actuation time is 6s when circulation, and upward stroke movement is 4s.
Detailed description of the invention
Fig. 1 is feed system structural schematic diagram in the embodiment of the present invention.
Fig. 2 is the flow diagram that feed system controls in the embodiment of the present invention.
In appended drawing reference: 1, hydraulic cylinder;2, push plate;3, hopper;4, crusher axis.
Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, and institute's attached drawing is only diagram of the present invention One kind, instead of all the embodiments.Based on the embodiments of the present invention, those of ordinary skill in the art are not making creation Property labour under the premise of every other embodiment obtained, shall fall within the protection scope of the present invention.
As shown in Figs. 1-2, the charging control method of the single-shaft crusher for RDF production line of the present embodiment, RDF production The number of the single-shaft crusher inlet amount of line is controlled by the electric current of crusher axis;The following steps are included:
S1, starting crusher, when in crusher hopper without material and crusher axis operating current be no-load current, crusher issue Alarm simultaneously stops operating.
S2, as shown in Fig. 1, when having material in hopper and the electric current of crusher work is less than broken material and fully relies on itself When gravity fall main shaft work electric current and be greater than crusher zero load when electric current, the push plate 2 on 3 inclined-plane of hopper is hydraulic It starts to work under the control of cylinder 1, the material being stuck on 3 inclined-plane of hopper is shifted on crusher axis 4.When push plate starts to act When down stroke time be 20s, time of upward stroke is 14s;Subsequently into cyclic process, push plate down stroke when circulation Actuation time is 6s, and upward stroke movement is 4s.
S3, when crusher operating current be greater than material fully rely on self gravity fall when main shaft operating current and be less than object The operating current of material gravity three times, persistently feeds at this time when material falls by self gravity.
S4, when crusher operating current be greater than material by self gravity fall when material gravity three times operating current and Five times of material gravity of operating current, slows down charging rate at this time when falling less than material by self gravity.
S5, it is greater than five times of material gravity of operating current when material falls by self gravity when crusher operating current, Stop charging at this time.
It although an embodiment of the present invention has been shown and described, for the ordinary skill in the art, can be with A variety of variations, modification, replacement can be carried out to these embodiments without departing from the principles and spirit of the present invention by understanding And modification, the scope of the present invention is defined by the appended.
