Description

Technical Field

[0001] The utility model relates to the field of chemical industry, in particular to a tubular belt tearing monitoring device. Background Art

[0002] At present, the main function of the tubular belt of the coking plant is to transport coke and coking coal. In order to improve transportation efficiency and reduce transportation costs, the tubular belt is used to transport the produced coke to the iron and steel plant, and the coking coal is transported from the wharf to the coking plant. The tubular belt is the main transportation pipeline of the coking plant.

[0003] In the daily production process, the coking coal returned to the factory will inevitably carry sharp foreign objects. At the same time, in the coke production process, the accessories on the coal loading car, coke quenching car, vibrating screen and other equipment, as well as the iron debris left over from the maintenance of such equipment, are easily mixed into the coke. In the process of transporting coke and coking coal by tubular belt, such debris entering the tubular belt will cause the tubular belt to tear, thereby causing leakage. Usually, a pull-rope tear switch is set under the tubular belt. When the foreign object penetrates the belt during transportation, it drives the pull-rope tear switch to stop the tubular belt. This pull-rope tear switch can only judge the foreign object that moves with the tubular belt when tearing the tubular belt. When the tubular belt is torn by a stationary foreign object or when it is aging and cracking due to long-term use, the tubular belt cannot be stopped in time, which can easily cause the tubular belt to tear seriously over a long distance. This increases the difficulty and repair cycle of emergency repairs, and affects the transportation of coke and coking coal in the coking plant, and affects the normal production of the coking plant.

[0023] like Figure 1As shown, according to an embodiment of the utility model, a tubular belt tear monitoring device is provided, including a flap 1 and a mechanical limit switch 4, wherein one end of the flap 1 is arranged below the tubular belt, and the mechanical limit switch 4 is arranged below one end of the flap 1. When the tubular belt leaks due to tearing, the leaked material falls on the flap 1, which can make one end of the flap 1 move downward to trigger the mechanical limit switch 4. After the mechanical limit switch 4 is triggered, the interlocking shutdown is started to stop the tubular belt. The mechanical limit switch 4 is connected with the pull-cord tear switch of the prior art, and the composite utilization rate is high, and the multi-point use effectively improves the reliability. Once the tubular belt is torn, the device triggers the interlocking protection in a short time, so that the tubular belt is immediately shut down, which effectively plays a role in protecting the tubular belt, avoids the risk of serious tearing of the tubular belt, effectively ensures the safety of the belt operation, and well compensates for the problem of insufficient pull-cord tear switch, prevents the expansion of equipment failure, and avoids personnel repair and personnel cleaning of coking coal, coke, etc.

[0024] Furthermore, the length direction of the flap 1 is from one end of the flap 1 to the other end of the flap 1, and the axis of the length direction of the flap 1 is perpendicular to the running direction of the tubular belt.

[0025] Further, the flap 1 includes a first section 5 and a second section 6. A flap shaft 2 is connected below the flap 1. The flap shaft 2 is set at about 1 / 3 of the length of the flap 1. The flap 1 between the flap shaft 2 and one end of the flap 1 is the first section 5. The flap 1 between the flap shaft 2 and the other end of the flap 1 is the second section 6. The length of the first section 5 is greater than the length of the second section 6. The first section 5 is located below the tubular belt, and the second section 6 is located outside the tubular belt. In one embodiment of the utility model, the flap 1 is 700 mm long, 600 mm wide, and 3 mm thick. The flap 1 is a stainless steel plate. The length of the first section 5 is 220 cm, and the length of the second section 6 is 480 mm.

[0026] Furthermore, a counterweight 3 is provided at the other end of the flap 1, and the counterweight 3 can tilt one end of the flap 1, that is, the counterweight 3 can make the height of one end of the flap 1 higher than the height of the other end of the flap 1. By using the principle of lever, when there is no leakage in the tubular belt, the two ends of the flap 1 are in a balanced state, and at this time, one end of the flap 1 remains tilted. When the tubular belt is broken or aged, and coke or coking coal falls onto the first section 5 of the flap 1, the balanced state of the two ends of the flap 1 is broken, one end of the flap 1 moves downward, and triggers the mechanical limit switch 4, which immediately stops the operation of the tubular belt. After the tubular belt is shut down, the specific location and cause of the leakage can be quickly checked, and the tubular belt can be maintained in time, effectively ensuring the safe operation of the tubular belt and preventing serious tearing of the tubular belt.

[0027] Furthermore, the distance between the highest point of the flap 1 and the tubular belt is 10 cm.

[0028] Furthermore, both ends of the flap shaft 2 enter into the shaft sleeve, and the shaft sleeve is a nut, and the nut is connected to the two side edges below the flap 1.

[0029] Furthermore, the outer edge of the upper surface of the flap 1 is provided with a convex edge, the height of which is 10 mm. When the tubular belt leaks, the convex edge can keep the leaked material on the flap 1, thereby ensuring that one end of the flap 1 moves downward and triggers the mechanical limit switch 4.

[0030] Furthermore, along the running direction of the tubular belt, a plurality of the devices are evenly arranged, and such an arrangement can provide a strong guarantee for the safe operation of the tubular belt.

[0031] The manufacturing and installation method of the device is as follows:

[0032] First, prepare a stainless steel plate with a length of 700mm, a width of 600mm, and a thickness of 3mm, weld 10mm high flanges on the four sides of the stainless steel plate, and fix a nut on each side of the stainless steel plate at about 1 / 3 of the length as the sleeve of the flap shaft 2. Then pass the flap shaft 2 through the two nuts, and fix the two ends of the flap shaft 2 on the bottom plate of the pipe belt machine. Weld a steel bar of appropriate weight as a counterweight 3 at the other end of the flap 1 to make one end of the flap 1 tilt up, and the flap 1 is installed. Finally, install the mechanical limit switch 4 below one end of the flap 1, and connect the mechanical limit switch 4 to the pull-rope tear switch after adjusting the installation position.

[0033] Check the flexibility of the flap shaft 2, whether the weight of the counterweight 3 is appropriate, manually debug the flap 1 repeatedly, and put the device into use after confirming that the signal is normal.

[0034] From the above description, it can be seen that the above embodiments of the utility model achieve the following technical effects:

[0035] A tubular belt tear monitoring device, once the tubular belt is torn, the device triggers interlock protection in a short time, causing the tubular belt to stop immediately, protecting the tubular belt, avoiding the risk of serious tearing of the tubular belt, effectively ensuring the safety of belt operation, and making up for the problem of insufficient pull-rope tear switch, preventing equipment failure from expanding, and avoiding personnel repair and personnel cleaning coking coal, coke, etc. The device has a simple structure, low manufacturing cost, easy installation, high sensitivity, and strong reliability.
