Abstract
The utility model discloses a monitoring device for blocking of the chute, namely, an auxiliary chute is arranged at the running direction where the chute faces to the conveyor; the auxiliary chute presents semi-closed type and is communicated with the chute; inside the auxiliary chute is provided with a heavy-hammer sensor which is connected with a control system by the data transmission to send the alarming signal. The heavy-hammer sensor can freely act at any directions; the coal flow in the chute is conveyed normally; the sensor is in normal close state; at this time, no signals are transmitted to the control center; when the coal flow in the chute is blocked, the heavy-hammer is gradually pushed incline by the coal flow till the sensor is in normal open state and the blocking signals are transmitted to the control center. The utility model could monitor the blocking condition of the chute accurately in order to prevent materials being overstocked on the chute and thereof causing the material leakage. Furthermore, the mistaken action resulted from big piece materials smashing on the sensor could be prevented.
Description
Technical field
The utility model relates to a kind of device that the monitoring material stops up in the material transportation of coal mining, relates in particular to the device that a kind of chute of monitoring in the belt conveyor system stops up.
Background technology
At present, in the dressing of coal by washing process of coal, the transportation of material is important link, but because various burst accidents and fault in the production process often cause the material transport system on-load to stop.In this case, if the equipment protection operation is unreliable, will directly causes solid accumulation in chute or on the equipment, thereby cause equipment can not normally move and a large amount of material from leakage.Therefore, must adopt the proper device monitoring to stop up, so that the material of in time getting rid of in the chute stops up, so that the protection operational outfit, the influence of reduction accident.The reliability that existing gate-type is stopped up monitoring device is low, often because the spring in resistance of anti-blocking badge or the device can not reset, causes that fender guard is failure to actuate or misoperation.
The utility model content
The purpose of this utility model is to provide a kind of monitoring device that can find timely and accurately that chute stops up.
To achieve these goals, monitoring device described in the utility model comprises chute, towards the service direction side of transport plane secondary chute is set at chute, this pair chute is semiclosed shape and communicates with chute, be provided with a heavily vertical formula sensor in the inside of secondary chute, this sensor links to each other by data transmission and control system.
The formula sensor that heavily hangs down described in the utility model can freely move in any direction, and when the normal conveying of the stream of the coal in the chute, coal stream does not contact with sensor, and sensor is in normally off, at this moment, does not have signal to import control center into; When the stream of the coal in the chute takes place to stop up, increase along with the coal amount in the secondary chute, described sensor and coal stream come in contact, the coal that its heavy vertical quilt is piled up is progressively pushed heeling condition to, be in normally open until sensor, and import jam signal into control center, control center receives after the described signal, can find the stopping state of coal stream, go to the scene to keep in repair mediation so that in time send someone.
Pound the mistake monitoring that the formula sensor that heavily hangs down is caused for fear of the coal stream of bulk, certain time-delay can be set in control system.Because the time that coarse coal stream acts on the sensor is extreme, is not enough to meet the time-delay that sets, therefore, still can make the formula sensor that heavily hangs down be in normally open, thereby guarantee that sensor the false alarm signal can not occur.
Described weight hammer type sensor is arranged on the position near secondary chute top usually, like this, has only when coal stream stops up and just can send alerting signal when height can touch sensor.
For the ease of maintenance, the openable dodge gate can be set in the front of secondary chute.
The cross-sectional plane of described closed secondary chute can be various suitable shapes, is preferably rectangle.
The utility model compared with prior art has the following advantages:
1) because the utility model is provided with secondary chute and sensor, can monitor the chute plugging fault in time, so that control center in time adjusts equipment operation and production, and dispatch officers to go to blocking position to overhaul mediation, and then prevent that material from overstocking on chute and the material from leakage that causes thus in a large number.
2) in control system of the present utility model, set time-delay, can prevent that bulk materials from pounding biography
The misoperation that sensor caused, thus the monitoring that chute is stopped up is more accurate.
Description of drawings
Fig. 1 is the scheme drawing of the main apparent direction of monitoring device described in the utility model;
Fig. 2 is the side schematic view of monitoring device described in the utility model when the obstruction of coal stream does not take place chute;
Fig. 3 is the side schematic view of monitoring device described in the utility model when chute coal stream stops up.
The specific embodiment
Below in conjunction with accompanying drawing chute described in the utility model being stopped up monitoring device is described in further detail.
Fig. 1 to Fig. 3 has shown that chute described in the utility model stops up an embodiment of monitoring device.Consult among the figure as can be known, be provided with the secondary chute 3 that communicates with chute 1 at chute 1 towards the service direction side of transport plane 2, this pair chute is semiclosed, and its cross-sectional plane is rectangular, and its front is provided with openable dodge gate; Be provided with a heavily vertical formula sensor 4 in the inside of secondary chute 3, this sensor 4 is positioned at the position of the top of secondary chute 3 apart from top 10cm.Sensor 4 can be one and become the tilt switch of often opening when being 10 °～15 ° at its angle of inclination, and can freely move in any direction, when the obstruction of coal stream takes place, increase along with the coal amount, tilt switch is pushed to obliquity by coal stream, when bevelled angle during at 10 °～15 °, the state that tilt switch is become often open, as shown in Figure 3, at this moment, tilt switch sends jam signal by data transmission to control system, and control system wherein can be Programmable Logic Controller PLC, and is not shown in the drawings.By programming installation and the production of PLC, and on control cabin computer simulation show screen, show failure message simultaneously, remind the timely handling failure of operating personal.When the normal operation of coal stream, tilt switch is not subjected to the influence of coal stream, remains on normally off always, and as shown in Figure 2, at this moment, the alerting signal that chute stops up can not appear in control center.In above-mentioned PLC, can set time-delay, the flase alarm that is caused when avoiding bulk materials to pound tilt switch.
