Fig. 1 is a schematic structural diagram of the present invention;
wherein: 1. the device comprises a signal transmission shaft, 2, a fixed mounting bearing, 3, a proximity switch, 4, a blocking piece, 5, a support, 6, a silt detection plate, 7, a material level, 8 and a discharge opening chute.
Detailed Description
The present invention will be described in further detail with reference to examples.
The utility model discloses a prevent detection device that blast furnace material loading belt silt material, see figure 1, include the signal transmission axle 1 that is in same water flat line with feed opening chute 8 opening, fixed mounting is served and set up the material pick-up plate 6 that becomes silted up in feed opening chute 8 at signal transmission axle 1, fixed mounting is at the separation blade 4 on the 1 other end of signal transmission axle, correspond and respond to complex proximity switch 3 with separation blade 4, a plurality of fixing device on the signal transmission axle 1 of setting between material pick-up plate 6 and separation blade 4 become silted up, through the alarm circuit that electrical control and proximity switch 3 are connected, the material pick-up plate 6 that becomes silted up sets up the rear position at the feed opening material stream. The silt detecting plate 6 and the signal transmission shaft 1 transmit signals through mechanical linkage, and the proximity switch 3 and the alarm loop realize alarm stop through electric control. The silt detecting plate 6 is arranged in a chute 8 of the feed opening and behind the material flow of the feed opening, so that the silt detecting plate is prevented from being smashed by a material source during normal feeding. The silt detecting plate 6 is fixedly arranged on the signal transmission shaft 1 and is fixed by screws or welded.
Each fixing device comprises a fixed mounting bearing 2 arranged on the signal transmission shaft 1, a bracket 5 connected with the fixed mounting bearing 2 and a buffer gasket arranged between the fixed mounting bearing 2 and the bracket 5. The horizontal edge of the bracket 5 and the opening of the feed opening chute 8 are positioned on the same horizontal line. The number of fixtures is 2-4, as the case may be, 2 in fig. 1. When the fixing device is installed, the bracket 5 of the signal transmission shaft 1 needs to be fixed firmly and needs to be positioned on the same horizontal line with the opening of the chute 8 of the feed opening, so that the signal transmission shaft 1 is ensured to rotate flexibly.
The signal transmission shaft 1 is made of a stainless steel pipe, in particular a 6-minute stainless steel pipe. The silt detecting plate 6 is fixed by screws or welding, and the silt detecting plate 6 is an iron plate with the specification of 3mm thick, 200mm long and 600mm wide.
The buffer gasket is a red copper alloy gasket or a rubber gasket. The alarm loop comprises a buzzer and a voice player connected with the proximity switch 3.
The proximity switch 3 adopts an inductive 2-wire proximity switch 3. Separation blade 4 of proximity switch 3 is fixed on signal transmission axle 1, adopts screw fixation or welding, ensures that separation blade 4 follows the rotation when the device action, can reach proximity switch 3's inductive distance. When proximity switch 3 installation is fixed, measure the interval between proximity switch 3 and the separation blade 4, ensure that proximity switch 3 can not be sensed when normal, only when separation blade 4 is rotatory, proximity switch 3 is just sensed and is sent out signal.
In fig. 1, when the normal belt is fed, the dropping direction of the material is parabolic, and the silt detection plate 6 is arranged at the inner side of the parabola, so that the material cannot be smashed.
When falling, the material is hit to the outer side of the chute mouth and then rolls to the inner side, and the material surface in the whole chute is in an inclined state with high outer side and low inner side.
The feed opening continuously feeds the next belt so that the level 7 in the feed opening chute 8 remains substantially as shown in figure 1, the level being inclined and not rising.
When a material block is large or a material source is mixed with impurities, the material outlet is blocked, the material level in the chute 8 of the whole material outlet continuously rises in an inclined manner, when the material level 7 reaches a certain height, the outer side material source rolls inwards, the material blocking plate 6 is touched to rotate along with the material level, and the proximity switch 3, the blocking piece 4 and the silt detecting plate 6 also rotate along with the material level on one shaft.
The silt is more, and silt material pick-up plate 6 pivoted angle is just bigger, and the turned angle of separation blade 4 is also bigger, and after reaching certain angle, proximity switch 3 senses separation blade 4, sends out the signal, and proximity switch 3 signal action back in time sends alarm signal, reminds post personnel to inspect the putty condition to avoid the emergence of production accident.
