Abstract
The utility model relates to the feeding control of a metallurgical mineral aggregate belt feeding system and provides a device of the metallurgical mineral aggregate belt feeding system for controlling the blockage of a hopper. The device utilizes micro-conductibility of metallurgical mineral aggregate to conduct the control. The device comprises a metal plate, cables, a relay switch, and a signal amplification circuit. The metal plate is installed on the upper part of an opening the hopper; the metal plate and the hopper body are isolated with each other by using insulation materials; the metal plate is connected to the signal amplification circuit; the signal amplification circuit ise connected to the relay switch; the signal amplification circuit serves as a control circuit of the relay switch; on-and-off contacts of the relay switch are communicated with a belt control system. Since the utility model adopts an electronic device, the incorrect manipulation and the blocking phenomena of the prior mechanical inspection device are avoided. The utility model has the characteristics of short responding time, immediate control and better control on the occurrence of blocking accident.
Description
Technical field
The utility model relates to the feed control of metallurgical mineral aggregate belt Feed system.
Background technology
In metallurgical production, various metallurgical mineral aggregates all are to transport with the belt Feed system.In actual production process, occur the material tide sometimes and block the situation that funnel or sintering deposit bulk block funnel, if find that belt untimely, out of service is late excessively, the material that not only has raft overfills, increases outside the labor content in post from funnel, more likely can cause and rub belt, cause sintering machine directly to stop production because of turning round by force.The anti-funnel blocking device of existing belt Feed system is generally mechanical detection equipment, misoperation occurs or moves phenomenon such as dumb through regular meeting, the out of reach expected effect.
The utility model content
Technical problem to be solved in the utility model provides the device that a kind of metallurgical mineral aggregate belt Feed system control funnel stops up, and it can detect funnel and be stopped up by mineral aggregate, and control belt Feed system is out of service.
For solving the problems of the technologies described above, the utility model provides the device of a kind of metallurgical mineral aggregate belt Feed system control funnel obstruction, and this device is to utilize the micro conductive of metallurgical mineral aggregate to control.It comprises metal sheet, cable, relay switch, signal amplification circuit, described metal sheet is installed in lural top, isolate with insulating material between metal sheet and the infundibular body, described metal sheet is by the described signal amplification circuit of cable connection, described signal amplification circuit connects described relay switch, signal amplification circuit is as the control circuit of relay switch, and the open close contact of relay switch inserts the belt control system.Metal sheet mainly plays induction effect, when the metallurgical material because of the obstruction heap touches metal sheet, metal sheet can be sent a current signal, through making relay closes after the signal amplification circuit amplification, after this signal is received by the belt Feed system, the belt control system will be sent the termination action command to belt transporter, thereby prevents funnel further to stop up, and avoids the belt Feed system is caused adverse effect.
Owing to device of the present utility model adopts electronic machine, not only avoided the maloperation or the stuck phenomenon of existing machinery detecting device, and had the response time weak point, the characteristics of instant control, the generation of energy better controlled putty accident.
Description of drawings
Fig. 1 is the scheme of installation of metal sheet in funnel.
Fig. 2 is relay switch control circuit figure.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.
The specific embodiment
As shown in Figure 1, little metal sheet 4 pads are gone up the inside front that is installed in funnel 1 on the insolator disc 2, make the insulation of little metal sheet 4 maintenances and funnel, material is to its interference when avoiding belt 3 normal operations, and with lead little metal sheet 4 is linked to each other with the relay switch control circuit, then relay switch is connected on the tight guard's valve of belt Feed system of production scene.Make the slowly stifled time-out of funnel when cross tide or bulk because of material, just have material to contact relay switch control circuit as shown in Figure 2 with little metal sheet 4, when Feed system is normally moved, aerotron T1 conducting, the relay adhesive, the contact of relay is normally moved belt feeder; Stifled during to little metal sheet 4 when the material in the funnel, because material all has certain electric conductivity, this moment, steel plate just quite with in ground linked to each other so, had formed closed circuit, just have electric current and pass through, thereby send signal, make aerotron T2 conducting, T1 ends, and relay disconnects, and makes the feed belt feeder out of service.Since must keep material and little metal sheet 4 reliable contact to switch on send signal, so the material that splashes is played the normal operation that can not influence belt in the of short duration contact of little metal sheet 4.
It should be noted last that, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, those of ordinary skill in the art is encompassed in the middle of the claim scope of the present utility model equally to the technical solution of the utility model simple modification done of relay switch control circuit or be equal to replacement for example.
