Description

Technical Field

[0001] This utility model relates to the field of mineral slurry concentration detection technology, and in particular to a mineral slurry high concentration alarm device. Background Technology

[0002] In the flotation process, the pulp concentration has a significant impact on the grade and recovery rate of the product concentrate, as well as on reagent consumption and water and electricity consumption. If the pulp concentration is too high, the mineral particles and bubbles cannot flow freely, which will damage the aeration conditions of the flotation machine, reduce the ore selectivity, and reduce the quality of the concentrate product. In addition, if the pulp concentration is too high, it will cause a decrease in the efficiency of the hydrocyclone classification, resulting in insufficient liberation of ore monomers, a decrease in flotation recovery rate, and a waste of resources.

[0003] To address the aforementioned issues, a high-concentration slurry alarm device was designed. This device automatically measures the slurry concentration and triggers a high-concentration alarm, allowing employees to be promptly reminded to adjust the amount of water added. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution:

A concentration box is provided below the sampling tube. The concentration box is provided with an overflow port to ensure stable sample volume. A collection hopper is provided below the overflow port. A solenoid valve is installed at the discharge end of the concentration box. A columnar support is installed at the lower end of the concentration box. A weighing scale is provided below the columnar support.

[0007] Preferably, the concentration box is also equipped with a second backwash solenoid valve.

[0008] Preferably, the first backflushing solenoid valve, the sampling solenoid valve, the solenoid valve, and the second backflushing solenoid valve are electrically connected to a first intelligent meter, a second intelligent meter, and a third intelligent meter.

[0009] Preferred: The sampling tube diameter is DN40-DN65.

[0010] Preferably, a manual gate valve is installed at the outlet diameter of the sampling tube.

[0011] Preferably, the weighing scale can be set with a weight limit, and an alarm will be triggered when the weight is exceeded.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This invention automatically measures the slurry concentration, enabling real-time and accurate acquisition of slurry concentration data, and triggering a high-concentration alarm. This facilitates timely reminders to employees to adjust the amount of water added, effectively ensuring the stability and continuity of flotation. Attached Figure Description

Detailed Implementation

[0017] This application provides a high-concentration slurry alarm device, which effectively solves the problem that excessively high slurry concentration in existing flotation processes can lead to decreased hydrocyclone classification efficiency, insufficient ore liberation, reduced flotation recovery rate, and resource waste. This utility model automatically measures the slurry concentration, enabling real-time and accurate acquisition of slurry concentration data and triggering a high-concentration alarm. This facilitates timely reminders to employees to adjust the amount of water added, effectively ensuring the stability and continuity of flotation. Example

The overall idea is as follows: A high pulp concentration alarm device includes a sampling tube with a diameter of DN40-DN65. A manual gate valve 1 is installed at the outlet of the sampling tube to facilitate handling equipment failures. A first backflushing solenoid valve 2 and a sampling solenoid valve 3 are installed on the sampling tube. The first backflushing solenoid valve 2 can prevent the sampling tube from being blocked. A concentration box 4 is set below the sampling tube, and the concentration box 4 is provided with an overflow port 5 to ensure the stability of the sample volume. A collection hopper 7 is installed below the overflow port 5. The collection hopper 7 can recover the discharged slurry and prevent the slurry from overflowing. A solenoid valve 6 is installed on the discharge end of the concentration box 4. A columnar support 9 is installed at the lower end of the concentration box 4. A weighing scale 10 is installed below the columnar support 9. The weighing scale 10 can be set with an upper limit weight. An alarm will be triggered when the upper limit is exceeded. A second backwash solenoid valve 8 is also installed on the concentration box 4. A first intelligent meter 11, a second intelligent meter 12, and a third intelligent meter 13 are electrically connected to the first backwash solenoid valve 2, the sampling solenoid valve 3, the solenoid valve 6, and the second backwash solenoid valve 8. The first intelligent meter 11, the second intelligent meter 12, and the third intelligent meter 13 can be adjusted. The start-up time and working cycle of the measuring device 13 are controlled to sequentially open and close the first backwash solenoid valve 2, sampling solenoid valve 3, solenoid valve 6, and second backwash solenoid valve 8. First, a sampling tube is welded to the opening on the slurry pipeline. The first intelligent measuring device 11, the second intelligent measuring device 12, and the third intelligent measuring device 13 are set to a working cycle of 5 minutes. Then, when the first intelligent measuring device 11 is working, it controls the opening of the sampling solenoid valve 3, and the sampled product enters the concentration box 4 through the pipeline. After running for 15 seconds, the first intelligent measuring device 11 controls the closing of the sampling solenoid valve 3, and the excess sample in the concentration box 4 flows into the collection hopper 7 through the overflow port 5 to the downstream operation. The weighing scale 10 reads the weight of the concentration box 4. The signal exceeds the set weight limit and triggers an alarm; the second intelligent measuring device 12 is set to start working 60 seconds after the weighing scale 10 starts working, at which time the solenoid valve 6 opens to empty the sampled product in the concentration box 4; the third intelligent measuring device 13 is set to start working 60 seconds after the second intelligent measuring device 12 starts working, and the third intelligent measuring device 13 controls the first backflushing solenoid valve 2 and the second backflushing solenoid valve 8 to open, in order to unclog the sampling tube and clean the concentration box 4. After running for 15 seconds, the third intelligent measuring device 13 controls the first backflushing solenoid valve 2 and the second backflushing solenoid valve 8 to close; the second intelligent measuring device 12 runs for 90 seconds and controls the solenoid valve 6 to close, completing one round of slurry concentration measurement process.

The weighing scale 10 reads the weight signal of the concentration box 4, and an alarm is triggered if the weight exceeds the set upper limit. The second intelligent meter 12 is set to... The weighing scale 10 starts working after 60 seconds. At this time, the solenoid valve 6 opens to empty the sampled product in the concentration box 4. The third intelligent meter 13 is set to start working 60 seconds after the second intelligent meter 12.
