Abstract
The utility model belongs to high-temperature calcination equipment and particularly relates to a system for detecting slab hogging of a pushed slab furnace by utilizing laser, which has a simple structure, is convenient and practical and can send out an alarm at the first time and stop the advancing of a hydraulic cylinder instantly after slab hogging happens. The system comprises a pushed slab furnace body, a hydraulic cylinder and a pushed slab arranged in the position corresponding to the hydraulic cylinder, wherein the pushed slab is arranged inside the pushed slab furnace body; a laser transmitter is arranged on the upper part at the front end of the pushed slab furnace body; a laser receiver is arranged in the position, corresponding to the laser transmitter, on the upper part at the tail end of the pushed slab furnace body; the laser transmitter and the laser receiver are respectively connected with a control system; and the control system is connected with an alarm device and the hydraulic cylinder respectively. The system has the following advantages: the system has a simple structure and is convenient and practical; and after slab hogging happens, the system can send out an alarm at the first time and stop the advancing of the hydraulic cylinder instantly.
Description
Technical field
The utility model belongs to high-temperature calcination equipment, is specifically related to a kind of simple in structurely, convenient and practical, occurs that very first time behind the arch bar reports to the police and hydraulic cylinder stops the laser acquisition pusher furnace arch bar system to advance immediately.
Background technology
Pusher furnace is a kind of high-temperature calcination equipment commonly used, is widely used in the industries such as battery material, pottery, has the serviceability temperature wide ranges, the characteristics such as the easy control of furnace atmosphere environment.Pusher furnace is when producing, and the square push pedal take hydraulic cylinder as 30-40 centimetre of powered monolithic length is advanced in the high temperature furnace chamber of tunnel type.Put the material that needs calcining in the push pedal, the mode with time interval of controlling each push pedal realizes the calcination time of control material high-temperature region in tunnel.For obtaining higher output, the pusher furnace tunnel is generally longer, nearly hundred of push pedal quantity.Be placed with again the material about 20 kilograms in every push pedal, in the Hydraulic Cylinder process, thrust is up to several tons.Unusual such as track, push pedal etc., the arch bar phenomenon easily occurs in the stove.After arch bar occured, pusher furnace advanced as continuing, and may produce destructive damage to burner hearth and track.Existing arch bar determination methods is: after 1, advancing a joint push pedal to stove, and manual observation finds that the stove back does not have push pedal to be pushed out, and is arch bar.2, naked eyes observe directly push pedal and dry by the fire.These two kinds of methods all need manual observation, if operating personnel not on request every propelling once observe once, just can not in time find arch bar.
Summary of the invention
The purpose of this utility model is to overcome defective of the prior art and provides a kind of simple in structure, convenient and practical, occurs that very first time behind the arch bar reports to the police and hydraulic cylinder stops the laser acquisition pusher furnace arch bar system to advance immediately.
The purpose of this utility model is achieved in that and comprises the push pedal that arranges on pusher furnace body of heater, hydraulic cylinder, the position corresponding with hydraulic cylinder, the inside that described push pedal is arranged on the slab furnace body of heater, the top of described pusher furnace body of heater front end is provided with laser beam emitting device, and the top of described pusher furnace body of heater end is provided with laser receiver on the position corresponding with laser beam emitting device; Described laser beam emitting device links to each other with control system respectively with laser receiver, and described control system links to each other with hydraulic cylinder with warning device respectively.
The utlity model has simple in structurely, convenient and practical, occur that very first time behind the arch bar reports to the police and hydraulic cylinder stops the advantage to advance immediately.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
As shown in Figure 1, the utility model comprises the push pedal 3 that arranges on pusher furnace body of heater 1, hydraulic cylinder 2, the position corresponding with hydraulic cylinder 2, the inside that described push pedal 3 is arranged on slab furnace body of heater 1, the top of described pusher furnace body of heater 1 front end is provided with laser beam emitting device 4, and the top of described pusher furnace body of heater 1 end and laser beam emitting device 4 are provided with laser receiver 5 on the corresponding position; Described laser beam emitting device 4 links to each other with control system 6 respectively with laser receiver 5, and described control system 6 links to each other with hydraulic cylinder 2 with warning device 7 respectively.
Operation principle of the present utility model is: hydraulic cylinder 2 promotes push pedal 3 and travels forward, when push pedal 3 normally travels forward, laser beam emitting device 4 and laser receiver 5 are started working simultaneously, laser beam emitting device 4 Emission Lasers are received by laser receiver 5, and this moment, control system 6 control warning devices were not worked; When arch bar occurs when, laser beam emitting device 4 Emission Lasers, and laser receiver 5 does not receive laser, control system 6 makes hydraulic cylinder 2 stop to advance when the control warning device is reported to the police.
Be placed with material 8 in the push pedal 3 of the present utility model, described laser beam emitting device 4 and laser receiver 5 specifically are arranged on the position above the following and material 8 at pusher furnace body of heater 1 top.
