Problems solved by technology

Due to the complex particle size and composition of the mineral material, and impurities will inevitably be mixed in during the production and processing process, the cyclone is often blocked irregularly
After the cyclone is blocked, its internal swirl state will change, not only cannot discharge fine material, but also affect the separation of coarse material, directly affecting the effect of material separation
At present, workers usually check the blockage of the cyclone regularly. This monitoring method has a large workload and poor timeliness, which seriously restricts the improvement of the analysis quality of mineral materials.

Embodiment 1

[0028] A clogging monitoring device for sorting equipment, including a cyclone 10, the cyclone 10 includes a first discharge port 11 communicated with a first material cavity 31 through a material guide pipe 13, and the opening is arranged in a second material cavity 32 The second discharge port 12 inside and the feed port 14 communicating with the mixing chamber 33, the first discharge port 11 or the second discharge port 12 are provided with a monitoring sensor 21, and the monitoring sensor 21 is connected to the alarm unit 50.

[0029] When the cyclone 10 is used to classify the particle size of the mineral material, since the movement speed of the mineral material in the cyclone 10 is fast and the hardness of the mineral material is relatively high, if the detection element of the monitoring sensor 21 is set in the cyclone 10 The cavity wall is easily damaged by the flowing mineral material, so the monitoring sensor 21 is set on the outer wall of the cyclone 10 in this embo...

Embodiment 2

[0034] The difference between this embodiment and the first embodiment lies in that several cyclones 10 are arranged in parallel, and the feed inlet 14 of each cyclone 10 communicates with the same mixing chamber 33 . Monitoring sensors 21 are respectively provided at the same part of each cyclone 10 , each monitoring sensor 21 is connected to a control unit 40 , and the control unit 40 is connected to an alarm unit 50 . That is, monitoring sensors 21 are respectively provided at the first discharge ports 11 of each cyclone 10 or monitoring sensors 21 are respectively provided at the second discharge ports 12 of each cyclone 10 . It should be further explained that the arrangement positions of the monitoring sensors 21 on each cyclone 10 should be the same or similar, so as to avoid deviations or errors in the detection results caused by different detection positions of the monitoring sensors 21 . In this way, if the discharge port of a certain cyclone 10 is blocked, the tempe...

Embodiment 3

[0039] The difference between this implementation and Embodiment 1 is that the feed inlet 14 of the cyclone 10 or its barrel 15 is provided with a reference sensor 22, and the monitoring sensor 21 and the reference sensor 22 are respectively connected with the control unit 40, and the control unit 40 The alarm unit 50 is connected; the reference sensor 22 and the monitoring sensor 21 are the same sensor.

[0040] In this embodiment, the monitoring sensor 21 is a contact temperature sensor, preferably a patch temperature sensor, which has good monitoring effect, high stability and reliability. The temperature sensing element of the monitoring sensor 21 for monitoring the temperature of the first discharge port 11 is attached to the outer wall of the first discharge port 11, and the temperature sensing element for monitoring the second discharge port 12 is attached to the second discharge port 12. On the outer wall of the material outlet 11 or the material guide pipe 13; the tem...

Abstract

The invention belongs to the technical field of smelting, and particularly relates to a blockage monitoring device of mineral slurry separation equipment and a control method of the blockage monitoring device. The blockage monitoring device comprises cyclones, each cyclone comprises a first discharge port, a second discharge port and a third discharge port, the first discharge ports are communicated with a first material cavity through material guide pipes, the second discharge ports are arranged in a second material cavity in an opening manner, and the feed ports communicated with a materialmixing cavity. By arranging monitoring sensors on or beside the cyclones, the change of a material outlet or a material inlet is monitored in real time under the condition that the working state of the cyclones is not influenced, so that the working state of the cyclones is known in time, the monitoring effect is accurate, the monitoring device is durable and reliable, and the product quality is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of copper smelting, and in particular relates to a blockage monitoring device and a control method of mineral slurry sorting equipment. Background technique [0002] At present, cyclones are usually used to classify the particle size of mineral materials. Due to the complex particle size and composition of the ore material, and impurities will inevitably be mixed in during the production and processing process, the cyclone is often blocked irregularly. After the cyclone is blocked, the state of the internal swirl will change, not only the fine material cannot be discharged, but also the separation of the coarse material will be affected, directly affecting the material separation effect. At present, workers usually check the blockage of the cyclone regularly. This monitoring method has a large workload and poor timeliness, which seriously restricts the improvement of the quality of mineral material analysis...
