Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of three-product cyclone equipment, and particularly relates to a jam alarm device for the gangue underflow port of a three-product cyclone. Background Technique
[0002] In coal production, a three-product cyclone separates raw coal into clean coal, medium coal, and gangue, and the gangue flows out from the gangue underflow nozzle of the three-product cyclone. In actual production, it is found that if the gangue content in the raw coal to be washed is too high or the processing capacity is too large, the gangue underflow nozzle is likely to be blocked. Since the operators in the centralized control room cannot discover the blockage of the cyclone underflow port in the first time, a large amount of gangue is discharged from the medium coal section, which not only affects the product quality, but also increases a large amount of labor and power consumption in the later re-washing or picking. Content of the Utility Model
[0003] The purpose of the utility model is to provide a jam alarm device for the gangue underflow port of a three-product cyclone to solve the above problems.
[0004] The utility model realizes the above purpose through the following technical solutions:
[0005] A jam alarm device for the gangue underflow port of a three-product cyclone includes a first-stage cyclone. One side below the first-stage cyclone is fixedly connected to a second-stage cyclone through a connecting pipe. A medium coal discharge port is arranged on one side of the second-stage cyclone. The gangue discharge port on the other side of the second-stage cyclone is located in a material box. An anti-blocking component is arranged in the material box. The anti-blocking component includes a proximity switch device arranged at the upper part of the material box. A rotating shaft is arranged on the proximity switch device. A swing rod rotatably installed on the rotating shaft is located inside the material box. A baffle fixed to the lower end of the swing rod is located at the gangue discharge port of the second-stage cyclone. The upper part of the proximity switch device is electrically connected to an alarm component.
[0006] Preferably, the proximity switch device includes a switch body and an infrared sensor.
[0007] Preferably, the alarm component includes a signal processing device. The input end of the signal processing device is connected to the infrared sensor in the proximity switch device through a wire. The output end of the signal processing device is connected to an alarm device through a wire.
[0008] Preferably, the alarm device is set as an audible and visual alarm.
[0009] Preferably, the baffle is set as a metal plate body.
[0010] The beneficial effects are as follows: The anti-blocking component provided by the present utility model makes up for the problem that the operator cannot detect in time after the underflow port of the second-stage cyclone is blocked. The overall structure of this alarm device is relatively simple and the work is reliable. During the actual production process, it can monitor in real time whether the underflow port of the second-stage cyclone is blocked, making the production process of the three-product cyclone more perfect and reliable, improving the production efficiency, eliminating the product quality accidents caused by the blockage of the gangue underflow port. This device is ingeniously designed, with small investment and low cost. Brief Description of the Drawings

[0015] The following further explains the technical solutions of the present utility model in conjunction with the drawings:
[0016] As Figure 1 shown, a gangue underflow port blockage alarm device for a three-product cyclone includes a first-stage cyclone 1. A connecting pipe is fixedly installed on one side below the first-stage cyclone 1. The lower end of the connecting pipe is fixedly connected to the second-stage cyclone 2. The first-stage cyclone 1 and the second-stage cyclone 2 are connected through the connecting pipe. A clean coal discharge port is opened on the other side of the first-stage cyclone 1.
[0017] A middling coal discharge port is opened on one side of the second-stage cyclone 2, and a gangue discharge port is opened on the other side of the second-stage cyclone 2. The gangue discharge port is located inside the feed box 3. An anti-blocking component is arranged inside the feed box 3. The anti-blocking component includes a proximity switch device 4 arranged at the upper part of the feed box 3. The proximity switch device 4 includes a switch body and an infrared sensor, which belongs to relatively mature prior art and will not be described in detail. A rotating shaft 5 is fixedly installed on the proximity switch device 4. A swing rod is rotatably installed on the rotating shaft 5. The swing rod is located inside the feed box 3. A baffle 6 is fixed at the lower end of the swing rod. The baffle 6 is set as a metal plate body. The baffle 6 is located at the gangue discharge port of the second-stage cyclone 2.
[0018] Above the proximity switch device 4, it is electrically connected to the alarm component. The alarm component includes a signal processing device 7. The input end of the signal processing device 7 is connected to the infrared sensor in the proximity switch device 4 through a wire. The infrared sensor can monitor the swing of the baffle 6 in real time. The output end of the signal processing device 7 is connected to the alarm device 8 through a wire. The alarm device 8 is set as an audible and visual alarm.
[0019] Working principle: During normal production, the gangue discharge port of the secondary cyclone 2 discharges gangue normally, and the gangue flow is discharged in an umbrella shape and impacts the metal baffle 6. The baffle 6 drives the swing rod to swing on the rotating shaft 5, and the infrared sensor installed on the feed box 3 senses the deflection signal, and the audible and visual alarm does not sound; when the underflow port is blocked, the baffle 6 does not deflect, and the infrared sensor does not sense the deflection signal. At this time, the infrared sensor transmits the monitored signal to the signal processing device 7, and the signal processing device 7 processes it and then transmits it to the audible and visual alarm for alarm, so as to remind the staff that the gangue discharge port of the secondary cyclone 2 is blocked and timely handle the blocked gangue.
[0020] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
