Description

Technical Field

[0001] The utility model relates to the technical field of pellet chain grates, in particular to a device for monitoring the reset state of a grate plate of a pellet chain grate. Background Art

[0002] Pellet grate plates are components used in pellet chains to clean and convey pellets (a granular material such as ore). The plates are plate-like components attached to the chain, and the movement of the chain removes the pellets from the hopper or conveyor equipment and conveys them to the next process step or container. These plates are typically designed to take into account the size and shape of the granular material to ensure efficient cleaning and conveying.

[0003] There are at least the following disadvantages in the use of existing pellet chain grate plates: during use, some of the existing pellet chain grate plates often cannot be reset in time and need to be manually inspected and reset. This is not only prone to missed inspections, but also has low manual inspection efficiency. Therefore, we have introduced a pellet chain grate plate reset status monitoring device.

[0027] See also Figure 1-4 , the utility model provides a technical solution:

[0028] A device for monitoring the reset status of a pellet chain grate machine grate plate comprises a support frame 1, the upper end of the support frame 1 is movably connected to a monitoring mechanism 8, a grate plate body 2 is provided on the upper part of the monitoring mechanism 8, an alarm 7 is fixedly connected to the lower front end of the support frame 1, the left and right ends of the support frame 1 are slidably connected to adjustment brackets 3, both of which are "U"-shaped structures, and a plurality of adjustment holes 4 are provided at the ends of the two adjustment brackets 3 that are away from each other, the lower ends of the two adjustment brackets 3 are commonly fixedly connected to a base 5, and the upper left and upper right parts of the base 5 are provided with mounting holes 6 that pass through from top to bottom.

[0029] In this embodiment, the monitoring mechanism 8 includes a movable plate 81, which is arranged at an angle. A protrusion 82 is fixedly connected to the middle part of the rear end of the movable plate 81, a No. 2 contact piece 83 is fixedly connected to the lower part of the rear end of the movable plate 81, and a buffer pad 84 is movably connected to the upper end of the movable plate 81; the buffer pad 84 is an "L"-shaped structure, with two No. 1 circular holes 841 opened at the upper end of the buffer pad 84, and two No. 2 circular holes 843 opened at the lower front end of the buffer pad 84, and screws 842 are movably inserted into the two No. 2 circular holes 843 and the two No. 1 circular holes 841; the four screws 842 are all threaded through the buffer pad 84 and are connected to the movable plate 81.

[0030] Through the above scheme: the unreset grate plate body 2 will not contact the movable plate 81, so that the angle of the movable plate 81 is adjusted, and the second contact piece 83 is in contact with the first contact piece 11. After the two contact, the circuit is closed, the alarm 7 is activated, and an audible and visual alarm is generated to warn the staff.

[0031] In this embodiment, the lower left and right ends of the support frame 1 are both threadedly connected with limit bolts 13, the upper end of the support frame 1 is provided with a groove 12, and the left and right groove walls of the groove 12 are both provided with rotating holes 14, and the upper front end of the support frame 1 is fixedly connected to a contact piece No. 1 1; the movable plate 81 is movably connected to the two rotating holes 14 through a rotating shaft; the two limit bolts 13 are respectively movably connected to the adjustment holes 4 on the two adjustment brackets 3.

[0032] Through the above solution: the support frame 1 is adjusted in height on the two adjustment brackets 3, and the support frame 1 is limited by two limit bolts 13, so that the entire device can adapt to the height of the grate plate, thereby improving the flexibility of use.

[0033] It should be noted that the present invention is a device for monitoring the reset status of the grate plates of a pellet chain grate machine. During use, when the grate plate body 2 is in its normal operating position, or reset state, it contacts the buffer pad 84. However, if the grate plate body 2 is not reset, it does not contact the buffer pad 84. When the grate plate body 2 is not reset, the angle of the movable plate 81 changes due to the lack of contact with the buffer pad 84. During this angle change, the second contact piece 83 contacts the support frame 1. When the second contact piece 83 contacts the first contact piece 11 fixed to the support frame 1, a circuit is closed, triggering the alarm 7 to activate. The activation of the alarm 7 is intended to warn personnel that the grate plate body 2 is not in the correct position. Because the support frame 1 is designed to be internal to two adjustment brackets 3, it can slide within the brackets to change its height. A limit bolt 13 is inserted into the adjustment hole 4 at different heights on the adjustment bracket 3 to lock the support frame 1 at a specific height.
