Abstract
The utility model relates to an automatic stop and free switch system for a material conveying process. The automatic stop and free switch system comprises an actuating mechanism mounted at a feeding or collecting operation point. The actuating mechanism is connected with a controller mounted in a remote control room through a signal communication wire. An automatic control electro-hydraulic three-way valve is arranged at a feed inlet of the material conveying process. The automatic stop and free switch system has the advantages that a belt conveyor can be delayed automatically or stopped sequentially by the aid of the controller, and accordingly, when materials are required to convey to two opposite destinations, non-interference free switch can be realized without interruption of the process, production energy consumption is saved effectively, production efficiency and equipment utilization rate are improved.
Description
Technical field
The utility model relates to a kind of automatically stopping and free switching system for the mass transport flow process.
Background technology
The stock ground material-transporting system is connected end to end by blowing, feeding equipment and many belt feeders and forms, flow process commonly used has more than 200 approximately, characteristics are that flow process is longer, stop to start frequent, program was loaded down with trivial details when flow process stopped, energy loss is large, and its shut down procedure is: blowing, material feeding operative employee notify blowing material feeding end Central Control Room operative employee to notify material terminal point post worker's terminal point post worker to observe on the belt without expecting that rear Central Control Room operative employee stops flow process., having caused belt feeder idle running, energy dissipation has reduced production efficiency.In addition, the blast furnace hopper that has can not take full advantage of effective volume, each feed supplement time is short, the flow process starting is frequent, and changes the storehouse because of long flow path at every turn, and starting, stopped process generally needed about 20 minutes, not only occupied production time but also be unfavorable for saving energy and reduce the cost, Fraquent start has a strong impact on also having brought in service life of the equipment such as on-the-spot high-voltage motor in addition, causes productive costs to increase, and production efficiency, capacity utilization rate reduce.
The utility model content
The purpose of this utility model is: for the problem of above-mentioned prior art existence; propose a kind ofly can shorten mass transport flow process time of run and according to the difference of mass transport terminal point, can free selection, undisturbed, do not shut down switch the mass transport flow process be used for automatically stopping and free switching system of mass transport flow process.
In order to reach above purpose, automatically stopping and free switching system for the mass transport flow process of the present utility model, its improvements are, comprise the actuating unit that is installed in blowing or material feeding operating point, described actuating unit is connected by the signal and communication line controller indoor with being installed in Long-distance Control, is provided with automatic control electric liquid triple valve at the feed opening of described mass transport flow process.
It is that described executive routine is connected with the control system of belt feeder by operating switch that the utility model further improves.
It is to be provided with the material-transporting system control program in the described controller that the utility model further improves.
The utility model has the advantage of: the automatic cut-off system of device for transporting objects of the present utility model adopts controller can realize that the automatic time delay of belt feeder sequentially stops, simultaneously can realize changing blast furnace, the automatic switchover when changing the storehouse, when material need to be carried to two rightabout terminal points, can be in the situation that does not stop flow process, realize that undisturbed freely switches, effectively save energy consumption, improved the production efficiency capacity utilization rate, reduced maintainer's work capacity.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Fig. 1 is structural representation of the present utility model.
1. mass transport starting point feed bin, 2. the first mass transport terminal point, 3. the second mass transport terminal point, 4. belt feeder, 5. actuating unit, 6. triple valve.
The specific embodiment
Embodiment one
The automatic cut-off system of the device for transporting objects of present embodiment, comprise the actuating unit that is installed in blowing or material feeding operating point, actuating unit is connected by the signal and communication line controller PLC cabinet indoor with being installed in Long-distance Control, executive routine is connected with belt feeder by operating switch, be provided with the material-transporting system control program in the controller, the belt feeder real-world operation half-turn time is time-delay order standing time.Wherein, the PLC control program is to arrange shutdown sequence according to the order of material conveying belt machine in the material loading flow process; and operating switch has been installed so that immediately send flow process along stopping order at each operating point; every flow process is provided with and triggers the belt feeder automatic sequence function of ceasing and desisting order in the control program; and the flow process between the large blast furnace does not need to stop public charging belt machine when switching; can directly finish flow process by the remote control room operation screen and freely switch, and guarantee that the interlocking between each belt feeder is safe and effective in the flow process.
During real work, count at first that each bar belt moves to the needed time of head in the flow process from afterbody, namely material is delivered to the required time of head from afterbody; In the PLC of material loading flow process control program, press belt feeder order and above-mentioned timing statistics and set time-delay order standing time; Revise automatic process, in every flow process, increase automatic danger signal; After on-the-spot blowing or feeding were complete, the operative employee pressed button switch, and PLC receives danger signal, and flow process i.e. time-delay sequentially stops, when both having guaranteed that flow process stops on the belt feeder without material, guaranteed that again belt feeder is without the idle running phenomenon; When wherein flow process stops, the time that stops in order between each belt feeder is the precise time of this belt feeder operation half cycle, and do not affect the function that each belt feeder is debugged separately running, the terminal belt feeder of two rightabout material terminal points can be freely in material conveying process in addition, undisturbed ground switches; When starting the reverse terminal point belt feeder of material and stopping forward terminal point belt feeder, the common part of whole conveying flow process need not stop.
Feed opening at material-transporting system in the utility model is provided with automatic control electric liquid triple valve, modification and perfection material loading process program correspondingly, achieve automatic switching function, and in the system from having the safety interlocking function between every belt feeder of material origin-to-destination, the safety interlocking function is also had in the startup of some belt feeder and the switching of triple valve; After oppositely belt feeder is opened the triple valve switching, the forward belt feeder can stop separately, do not affect the normal operation of back flow process, oppositely the interlock connection of belt feeder and back flow process is set up voluntarily simultaneously, the required device for transporting objects that uses can meeting in the situation of site technique, freely be selected, be made up by the remote control room operator in the mass transport flow process.
In addition to the implementation, the utility model also can have other embodiments.All employings are equal to the technical scheme of replacement or equivalent transformation formation, drop on the protection domain of the utility model requirement.
