Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of alarm devices, and more specifically, to an alarm device for preventing counterfeiting on conveyor belts used in mineral processing. Background Technology
[0002] In daily operation, the anti-overflow device on the conveyor belt of iron ore beneficiation plants typically uses a rotary paddle level gauge, usually installed inside the chute. This gauge often malfunctions due to being struck by ore blocks, causing the conveyor belt to leak and overflow. This requires operators to clean it every shift, which is labor-intensive for workers. Furthermore, the confined space around the conveyor belt poses safety hazards for cleaning personnel, and the belt needs to be stopped during cleaning, affecting ore loading efficiency. Therefore, a new type of anti-overflow and alarm device for conveyor belts in mineral processing is needed, which automatically alarms when overflow occurs. Utility Model Content

Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.
[0025] Unless otherwise specifically stated, the relative arrangement, numerical expressions, and values of the components and steps described in these embodiments do not limit the scope of this invention. It should also be understood that, for ease of description, the dimensions of the various parts shown in the drawings are not drawn to actual scale. Techniques, methods, and devices known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and devices should be considered part of the specification. In all examples shown and discussed herein, any specific values should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters in the following figures denote similar items; therefore, once an item is defined in one figure, it need not be further discussed in subsequent figures.
[0026] In the description of this utility model, it should be understood that the orientation or positional relationship indicated by directional terms such as "front, back, up, down, left, right", "horizontal, vertical, horizontal" and "top, bottom" is usually based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the scope of protection of this utility model.

[0029] like Figure 1-2 As shown, this utility model provides a device for preventing cargo leakage and alarming on a conveyor belt for mineral processing, which is installed on the conveyor belt of an iron ore processing plant. It includes: an observation hole (400 mm × 600 mm), a movable door, an anti-blocking device, and a vibrator.
[0030] The observation hole is located on either side of the front chute of the iron ore beneficiation plant belt conveyor; the vibrating wall device is located on the trough wall of the front chute of the iron ore beneficiation plant belt conveyor.
[0031] The observation hole is equipped with the movable door; the anti-blocking device is located on the inside of the movable door.
[0032] Preferably, in this application, the anti-blocking device includes: a lever, a baffle, a proximity switch, and a relay; one end of the lever is connected to the baffle, and the other end is connected to the proximity switch after being pressed down; the proximity switch is connected to the relay.
[0033] The anti-blocking device utilizes the lever principle. When the chute ahead is blocked, ore or debris presses against the baffle at one end of the lever, while the other end touches a proximity switch. The normally open contact of the proximity switch closes, energizing a time-delay relay. The normally open contact of the proximity switch remains closed for 3 seconds (to prevent malfunctions caused by individual ore impacts). The normally closed contact of the time-delay relay then opens, de-energizing the unloading conveyor contactor and stopping the unloading conveyor. The unloading conveyor is interlocked with the next process conveyor; its stop interlocks with the next process conveyor stopping, thus ensuring that loading stops when the chute is blocked, preventing sluggish loading. Considering that the acceptable ore particle size is less than 25mm, the baffle size in this application is 40mm × 50mm.
[0034] After the unloading conveyor belt stops and the next process conveyor belt stops, the automatic control system starts the vibrator installed on the chute wall to vibrate and strike large pieces or debris in the chute for 10 seconds. During the 10 seconds of vibration, the normally open contact of the vibrator contactor closes. After the large pieces or debris are shaken off, the ore or debris no longer presses against the baffle at one end of the lever, and the other end of the lever moves away from the proximity switch. The normally open contact of the proximity switch opens, the energizing delay time relay KT1 is de-energized, the normally closed contact of the energizing delay time relay KT1 closes and the normally open contact opens, the coil of the unloading conveyor belt contactor KM1 is energized and the conveyor rotates, the normally open contact of the unloading conveyor belt contactor KM1 closes, the coil of the horizontal belt KM2 is energized and the conveyor rotates.
[0035] If the large pieces or debris inside the chute are not shaken off after the vibrator strikes them for 10 seconds, it indicates that the size of the ore or debris has exceeded the size of the discharge port at the bottom of the chute. At this time, the ore continues to press against the baffle at one end of the lever, and the automatic control system transmits a signal to the staff rest room. The staff rest room is equipped with an audible and visual alarm device to facilitate the staff to deal with the chute blockage in a timely manner. After the staff has dealt with the blockage, they manually start the unloading conveyor belt and the conveyor belt for the next process.
[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this utility model.
