[0025] like Figure 1-Figure 3 As shown, the utility model proposes a dust removal device for a coke intercepting car.

[0026] In an exemplary embodiment, the dust removal device of the coke intercepting car includes:

[0027] A ventilation slot 1 is provided, the ventilation slot 1 is extended along the traveling direction of the coke intercepting vehicle, a collecting channel is provided in the ventilation slot 1, and a belt is provided on the top surface of the ventilation slot 1 to cover the collecting channel;

[0028] A dust collecting hood 2 is movably arranged on the ventilation slot 1 and moves synchronously with the coke intercepting vehicle. A roller assembly is provided on the dust collecting hood 2 for belt guiding;

[0029] The sensing component is arranged on the dust collecting cover 2 and is used for detecting the running state of the belt. The sensing component is interlocked with the coke intercepting vehicle.

[0030] In this embodiment, the sensor component is interlocked with the coke intercepting car, so that the status of the belt can be monitored in real time, and the operator can be reminded in time when the belt runs off the edge or breaks, so as to avoid further expansion of the accident, reduce the maintenance intensity of the fault, and ensure the safe production of the coke oven.

[0031] In an exemplary embodiment, the sensing component includes a deviation sensor 6 and a break sensor 7. The deviation sensor 6 and the break sensor 7 are both arranged on the dust collecting cover 2 and are used to sense the deviation state and integrity state of the belt respectively.

[0032] In this embodiment, the deviation sensor 6 and the break sensor 7 are installed on the dust hood 2, and move synchronously with the dust hood 2. After the dust hood 2 lifts up the belt through the roller assembly, the deviation sensor 6 and the break sensor 7 perform real-time and uninterrupted sensing of the protruding belt to avoid the situation where the belt cannot be detected after it becomes abnormal.

[0033] Illustratively, in this embodiment, an alarm (not shown in the figure) is provided on the dust collecting hood 2 , and the alarm is electrically connected to the deviation sensor 6 and the fracture sensor 7 .

[0034] In this exemplary embodiment, the deviation sensor 6 includes a plurality of pairs of deviation switches arranged on the dust cover 2, each pair of deviation switches being arranged in the belt width direction and the belt being located between the deviation switches. In this embodiment, two pairs of deviation switches are arranged, which are respectively located at the front and rear sides of the dust cover 2. Since the spacing between the deviation switches is greater than the width of the belt, under normal conditions, the belt will not touch the deviation switches during continuous movement. If the belt runs off the side, the belt will touch the deviation switch on one side, and the deviation switch can sense that the belt has run off the side, and an alarm is issued, and whether to stop the machine is determined according to the severity of the running off.

[0035] For example, in this embodiment, each deviation switch has two modes. Each deviation switch has two pairs of normally open contacts built in, which are used as signal points for light and heavy deviation respectively, and are connected to intermediate relays respectively. In this embodiment, the design is that the light deviation signal alarms, and the heavy deviation signal alarms and stops the vehicle. Figure 3 As shown, taking one of the deviation switches as an example (the left deviation switch), when the belt slightly deviates, it contacts the deviation switch (S1), causing the deviation switch (S1-1) contact to close, the intermediate relay (KA1) coil connected in series to be energized and attracted, the corresponding normally open auxiliary contact (KA1) to close, and the alarm (HA1) to be energized and operated. The alarm (HA1) gives an audible and visual alarm, reminding the driver that a slight deviation fault has occurred on site and to operate with caution; if the deviation becomes more and more serious at this time, the deviation switch (S1-2) contact closes, the intermediate relay (KA2) coil connected in series to be energized and attracted, the corresponding normally open auxiliary contact (KA2) to close, and the signal light (HL1) to be energized and operated, and at the same time the normally closed contact (KA2) connected in series to the interlocking branch is disconnected, and the entire trolley movement is terminated. The other deviation switches have the same working principle as the above deviation switches.

[0036] Exemplarily, the break sensor 7 is a proximity switch, which is arranged close to the belt and has a sensing gap between the belt and the belt, and is installed at a position close to the middle of the belt, such as Figure 2 shown.

[0037] In this exemplary embodiment, there are two break sensors 7, one at the front and one at the rear of the dust hood 2. The working mode of this embodiment is that as long as one of the signal detections is lost, an alarm is sounded and the vehicle stops. When the belt is normal, the proximity switch (SQ1, SQ2) detects an object, the switch is in a normally closed state, the coil of the intermediate relay (KA9, KA10) connected in series with the branch is energized and attracted, the normally closed contacts (KA9, KA10) of the alarm branch are disconnected, the alarm indicator light is in a power-off state, the normally open contacts (KA9, KA10) of the interlocking branch are closed, and the interlocking is in an engaged state. When the belt is broken, the proximity switch used for detection remains in a normally open state because it cannot detect an object, the normally closed contacts (KA9, KA10) remain in a closed state without power, the alarm indicator (HL5, HL6) is energized to sound an alarm, the normally open contacts (KA9, KA10) of the interlocking branch remain disconnected, and the interlocking branch is disconnected.

[0038] It is worth noting that the interlocking condition in this embodiment is that the re-running signals of the four deviation switches are not triggered, and there is a signal in the belt state detection, and the above 6 signals are all in series. After the interlocking condition is met, the interlocking relay (KA0) coil of the dust removal belt system is energized and closed, and its normally open contact (KA0) is also closed, completing the interlocking of the induction component and the coke intercepting car running mechanism, otherwise the interlocking circuit is in an open circuit state, and the coke intercepting car trolley does not run. Figure 3 ①~⑤ in the figure are other interlocking points of the coke intercepting car, KM is the external interlocking contactor of the coke intercepting car, and the normally open auxiliary contact of KM is connected in series to the allowed running branch in the original coke intercepting car circuit. Considering the maintenance status, a forced unlocking mode is also set. Simply put the conversion switch (SA) in the closed state to release the interlocking state of the dust removal belt system, meeting the need for moving the car during maintenance.

[0039] It should also be noted that in this embodiment, other sensors can be used or the two sensors in the sensing assembly can be installed at different positions to sense whether the belt is running or broken. For example, sensors can be installed at various locations on the ventilation slot 1 to sense whether the belt is broken or running.

[0040] like Figure 1 In an exemplary embodiment, the roller assembly includes a nip roller, a support roller and a steering roller, and the belt passes through the nip roller and is wound around the support roller and the steering roller and then passes out from the nip roller.

[0041] In this embodiment, the belt passes through the pressure wheel-support wheel-steering wheel-steering wheel-support wheel-pressure wheel in sequence, so that the belt can open the corresponding position during the movement of the dust hood 2, so that the internal space of the dust hood 2 is connected with the collection channel of the ventilation groove 1, and the dust collected by the coke intercepting car can pass through the dust hood 2 and enter the interior of the collection channel.

[0042] Illustratively, in this embodiment, the dust hood 2 is detachably connected to the coke intercepting vehicle, and running wheels 8 are provided at the bottom of the dust hood 2, wherein when the coke intercepting vehicle moves, the dust hood 2 moves on the ventilation slot 1 via the running wheels 8.

[0043] Exemplarily, a fan 9 is provided at one end of the ventilation slot 1 for collecting dust in the ventilation slot 1 .

[0044] In summary, the utility model monitors the real-time status of the belt during the movement of the dust collecting hood 2 by means of the induction component arranged in the coke intercepting car chain, so that the operator can find out in time when the belt runs off the edge or breaks, thus effectively avoiding further expansion of the accident.

[0045] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
