[0002] During the beneficiation test process, in order to accurately understand whether the beneficiation process, reagent system, etc. are appropriate, it is usually necessary to sample the pulp products at each separation stage for analysis of concentration, fineness, grade, etc., so as to grasp the flotation effect in a timely manner and make judgments and adjustments in a timely manner. Therefore, the accuracy of the selection of pulp liquid is extremely important.

[0003] At present, the traditional sampling method generally uses a rubber tube filled with water, blocks one end, and puts the other end into the flotation cell, and uses the U-tube principle to extract the pulp liquid. The defects of the traditional sampling method are as follows:

[0004] 1. There is a certain amount of water in the rubber tube, which will affect the concentration of the pulp sample;

[0005] 2. The extraction process and sampling volume of the pulp liquid are completely judged by the experimental operator based on experience, and quantitative sampling cannot be achieved;

[0006] 3. After sampling, it is not convenient to clean the pipeline and add the same amount of water to the flotation cell to ensure the liquid level balance of the flotation cell;

[0007] In view of the above defects, the utility model provides an automatic pulp sampling device. Summary of the Utility Model

The control buttons 7 include digital buttons, a switch button and a power switch light. A sampling pipe 2 is arranged on the top of the housing 1. A hose (not shown in the drawings) can be connected to the sampling pipe 2 and the other end of the hose is extended into the pulp liquid. A sample discharge pipe 3 and a clear water pipe 4 are arranged at the bottom of the housing 1. Hoses (not shown in the drawings) can also be connected to the sample discharge pipe 3 and the clear water pipe 4. A flow sensor 9 is arranged inside the housing 1. The flow sensor 9 is connected to the sampling pipe 2 and the other pipe orifice of the flow sensor 9 is connected to a water pump 10 through a short pipe 15. The pulp liquid is pumped by the water pump 10 and measured by the flow sensor 9. The other pipe orifice of the water pump 10 is connected to a two-position three-way solenoid valve 11 through a short pipe 15. The other two pipe orifices of the two-position three-way solenoid valve 11 are respectively connected to the sample discharge pipe 3 and the clear water pipe 4. A single-chip microcomputer 14 is also arranged inside the housing 1. The display screen 5, the control buttons 7, the flow sensor 9, the water pump 10 and the two-position three-way solenoid valve 11 are respectively electrically connected to the single-chip microcomputer 14. A fixing mechanism is also arranged on the housing 1 to fix the housing 1 on a flotation machine or other equipment.

[0026] A further solution of this embodiment is that a buzzer 6 is also provided on the front side of the housing 1. The buzzer 6 is electrically connected to the single-chip microcomputer 14, and the operator can be reminded by the buzzer 6 after the sampling process and the cleaning process are completed. The fixing mechanism is a magnetic backplane 8, and the magnetic backplane 8 is arranged on the rear side of the housing 1. A waterproof partition 13 is arranged in the housing 1 to divide the housing 1 into two left and right regions. The single-chip microcomputer 14 is located in the left region of the waterproof partition 13, and the flow sensor 9, the water pump 10 and the two-position three-way solenoid valve 11 are all located in the right region of the waterproof partition 13, so as to prevent liquid leakage from affecting electronic components such as the single-chip microcomputer 14. In addition, a drain hole 12 is provided at the bottom of the housing 1, and the drain hole 12 is located in the right region of the waterproof partition 13, so as to facilitate the discharge of the leaked liquid in the housing 1.

[0027] The working process of the present utility model is as follows: The housing 1 is fixed on the flotation machine through the magnetic backplane 8. A hose is connected to the sampling pipe 2 and the end of the hose is extended into the ore slurry. The sampling volume and sampling time are set through the control button, and the cleaning of the sampling pipeline is set after the sampling is completed. After the setting is completed, the water pump 10 starts to work. The ore slurry enters the flow sensor 9 through the sampling pipe 2, flows through the water pump 10 and reaches the two-position three-way solenoid valve 11. At this time, the two-position three-way solenoid valve 11 switches to open the sample discharge pipe 3 and closes the clear water pipe 4 to discharge the ore slurry. When the liquid volume of the flow sensor 9 reaches the set value, the water pump 10 stops the sampling work;

[0028] After the sampling process is completed, the water pump 10 rotates in reverse and at the same time the two-position three-way solenoid valve 11 switches to close the sample discharge pipe 3 and open the clear water pipe 4. At this time, the water pump 10 pumps clear water to return to the flotation cell through the sampling pipe 2. When the amount of the cleaning water flowing through the flow sensor 9 reaches the preset value, the cleaning work is completed and the water pump 10 stops working; When the sampling process and the cleaning process are completed, the buzzer works to prompt the experimenter that the sampling work has been completed.
