[0002] As a crucial source of iron raw materials for the metallurgical industry, the continuity of sintering production and the quality of sintered ore are of paramount importance for sintering machines. The ignition furnace, as the core equipment of the sintering machine production line, directly affects the output and quality of sintered ore. Derailment is a common process defect that can lead to malfunctions in the sintering machine, reduced production line efficiency, or even shutdown. Derailment refers to a safety hazard caused by the ignition furnace deviating from its track. Currently, most domestic sintering process specifications for ignition furnaces focus on securing them to prevent mechanical displacement. If derailment is not corrected promptly, it can escalate to deviations of the sintering machine trolley. Utility Model Content

Detailed Implementation

Obviously, the embodiments described are only a small part of the utility model embodiments, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the utility model without creative effort are within the protection scope of the utility model.

[0011] A sintering machine ignition furnace derailment detection device includes an ignition furnace 3, an ignition furnace track 12, a sintering machine trolley 13, and a sintering machine trolley track 14. The ignition furnace track 12 and the sintering machine trolley track 14 are arranged parallel to each other, with the ignition furnace track 12 located on the outer side and the sintering machine trolley track 14 located on the inner side. The ignition furnace 3 travels on the ignition furnace track 12, and the sintering machine trolley 13 travels on the sintering machine trolley track 14. The sintering machine trolley 13 can enter the ignition furnace 3 for ignition. The ignition furnace 3 is equipped with a stop 10, and a proximity switch 5 matching the position of the stop 10 is provided next to the ignition furnace track 12. The proximity switch 5 is mounted on a proximity switch bracket 8 by fixing screws 7, and the proximity switch bracket 8 is fixed to the ground next to the ignition furnace track 12 by fixing bolts 9.

[0012] There are four derailment detection blocks 10: south derailment detection block 1-1, north derailment detection block 1-4, south position detection block 2-1, and north position detection block 2-4. South derailment detection block 1-1 and north derailment detection block 1-4 are welded to the north and south sides of the ignition furnace head 3, respectively, and south position detection block 2-1 and north position detection block 2-4 are welded to the north and south sides of the ignition tail, respectively. There are four proximity switches: south derailment proximity switch 1-3, north derailment proximity switch 1-6, south position proximity switch 2-3, and north position proximity switch 2-6. Each proximity switch is matched with the installation position of its respective detection block.

[0013] There are four proximity switch brackets 8, namely, south derailment proximity switch bracket 1-2, north derailment proximity switch bracket 1-5, south position proximity switch bracket 2-2 and north position proximity switch bracket 2-5, and each proximity switch is installed on its respective proximity switch bracket.

[0014] The ignition furnace 3 moves on the ignition furnace track 12 via the track wheels 4, and the sintering machine trolley 13 moves on the sintering machine trolley track 14 via the main motor 15 and the main motor drive 16.

[0015] The track wheel 4 is connected to the ignition furnace 3 via the ignition furnace track wheel bracket 11.

[0016] The proximity switch 5 transmits a switching signal via signal line 6.

[0017] In practical applications, the proximity switch bracket measures 300mm*50mm. A 25mm diameter circular hole is opened 5mm from the top of the proximity switch bracket. The proximity switch has a diameter of 20mm, and four proximity switches are installed in the four circular holes of the proximity switch bracket.

[0018] The distance between the proximity switch and the detection stop is 20±5mm.

[0019] The dimensions of the detection stop are 300mm*50mm.

[0020] Welded blocks are installed on the sides and front of the tracks on the north and south sides of the ignition furnace, with the proximity switch maintaining a distance of 20±5mm from the blocks.

[0021] During operation, proximity switches and stops are installed at four detection points and kept in operation. If the ignition furnace derails or shifts beyond the detection distance in a certain direction, the signal of the proximity switch at the corresponding position will immediately disappear, and an alarm interlock signal will be sent to the sintering machine to prevent more serious situations from occurring. Example

[0022] This invention is applied to the detection of the ignition furnace position of the No. 3 sintering machine in a steel company.

[0023] During operation, proximity switches installed at four different locations on the ignition furnace can detect the degree of displacement exceeding the limit or the derailment signal. When the ignition furnace derails or the displacement exceeds the limit at a certain point, the proximity switch signal disappears, and the alarm signal is immediately transmitted to the sintering machine control system to further determine whether the sintering machine trolley speed needs to be adjusted to reduce the probability of process failure.

[0024] This invention can accurately and timely detect the displacement of the ignition furnace track side and track direction in the sintering machine, and can intuitively reflect the displacement of the ignition furnace, thereby improving the monitoring level. In addition, it can make a derailment alarm based on the proximity switch signal, and make reasonable preventive control of the sintering machine operation.
