Description

Technical Field

[0001] The utility model relates to the technical field of flotation and ore dressing detection tools, in particular to a flotation and ore dressing aeration volume measuring device. Background Art

[0002] Flotation beneficiation technology is a key means to achieve effective separation and enrichment of target minerals in current mineral processing technology. It uses the differences in the physical and chemical properties of the target minerals to make the target minerals selectively attach to bubbles and then rise to the surface of the slurry, ultimately achieving effective separation of the target minerals from the gangue minerals. In flotation beneficiation, the amount of aeration is an important factor affecting the separation index of the target minerals. Convenient, accurate and fast measurement of the amount of aeration in the flotation beneficiation process is of great significance to the optimization of the flotation beneficiation process and the efficient separation of minerals.

[0003] In actual production, the water drainage and gas collection method is often used to measure the amount of inflation. Usually, a glass tube with one end sealed and with a scale is used. After the glass tube is filled with clean water, the open end is inverted and inserted vertically into the slurry. The bubbles generated in the slurry enter the glass tube and cause the liquid level in the glass tube to drop. The inflation amount is calculated by recording the time it takes for the liquid level to drop to the preset scale interval.

[0004] In the above process, it is necessary to use paper or other shielding objects to cover the sealed end of the glass tube, and remove it when the open end of the glass tube is vertically inserted below the slurry surface to prevent water from leaking out of the glass tube and entering the air during the inversion of the glass tube. In actual operation, shielding objects often fall off when the glass tube is inverted or the open end of the glass tube is vertically inserted into the slurry, resulting in the inability to obtain measurement data or distorting the measurement data, affecting the subsequent inflation volume adjustment work.

[0025] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. In the absence of conflict, the embodiments and features in the embodiments of the utility model can be combined with each other. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0026] Figure 1 An embodiment of a flotation and mineral processing aeration volume measuring device of the utility model is shown, see Figure 1 In this embodiment, the flotation and mineral processing aeration volume measuring device includes: a device body 1 and a shielding component 2.

[0027] Among them, see Figure 1The device body 1 is provided with a measuring cylinder 11, which is a cylindrical structure with one end sealed; the shielding assembly 2 is provided with a baffle 21, a connecting rod 22 and a push rod 23. At least one baffle 21 is suspended at the open end of the measuring cylinder 11, and the end surface of each baffle 21 adjacent to the measuring cylinder 11 is connected to one end of a connecting rod 22, and the other end of each connecting rod 22 is connected to one end of a push rod 23. The other end of the push rod 23 extends from the open end of the measuring cylinder 11 into it and penetrates the sealed end of the telescopic measuring cylinder 11. The push rod 23 is inserted and pulled out at the sealed end of the measuring cylinder 11 to drive the push rod 23 to move along the axial direction of the measuring cylinder 11. The push rod 23 moves along the open end of the measuring cylinder 11 to drive the baffle 21 away from the open end of the measuring cylinder 11, and the push rod 23 moves along the sealed end of the measuring cylinder 11 to drive the baffle 21 to approach and cover the open end of the measuring cylinder 11, thereby completing the opening or closing process of the open end of the measuring cylinder 11. By pulling the push rod 23 at the sealed end of the measuring cylinder 11, when the open end of the measuring cylinder 11 is inverted or vertically inserted below the slurry surface, it is possible to prevent gas from leaking into the open end of the measuring cylinder 11, thereby preventing the inflation volume measurement data from being invalid.

[0028] Further, see Figure 2 The device body 1 is also provided with a support tube 12, which is coaxially installed in the measuring cylinder 11. One end of the support tube 12 passes through the sealed end of the measuring cylinder 11. The support tube 12 is simultaneously sleeved on the connecting rod 22 and the outside of each push rod 23 to limit the push rod 23 and each connecting rod 22 so that the push rod 23 can only move along the axial direction of the measuring cylinder 11.

[0029] Further, see Figure 2 The device body 1 is also provided with a limit rod 13, which is arranged at the open end of the support cylinder 12. The limit rod 13 separates the open end of the support cylinder 12 into at least two through holes arranged in a ring around the axis of the support cylinder 12. Each limit rod 13 passes through each through hole, so that when the push rod 23 moves toward the open end of the measuring cylinder 11, the ends of the connecting rods 22 connected to the baffles 21 can move away from each other, thereby driving each baffle 21 away from the axial space of the open end of the measuring cylinder 11, so that the space under the slurry liquid surface facing the open end of the measuring cylinder 11 is not blocked by the baffle 21, thereby preventing the open end of the measuring cylinder 11 from being blocked and affecting the bubbles in the slurry from entering the measuring cylinder 11, thereby avoiding data distortion of the inflation volume measurement.

[0030] Furthermore, the ends of each two adjacent baffles 21 close to each other are linear sides, and the ends of each two adjacent baffles 21 close to each other are abutted, so that each baffle 21 forms a plate-like structure and completely covers the sealed end of the measuring cylinder 11, so that a sealed space is formed in the measuring cylinder 11.

[0031] Optionally, the present embodiment is configured with two baffles 21, two connecting rods 22, and a limiting rod 13 as the best embodiment, and the corresponding open end of the measuring cylinder 11 is separated into two through holes arranged in a ring around the axis of the supporting cylinder 12, and each of the two through holes passes through a connecting rod 22.

[0032] For example, the middle parts of the two connecting rods 22 and the ends thereof connected to the baffle 21 are all located outside the support tube 12. The control push rod 23 moves toward the sealed end of the sleeve, which can drive the two connecting rods 22 to enter the support tube 12. Under the limiting action of the support tube 12, the ends of the two connecting rods 22 away from the push rod 23 will approach each other, thereby driving the two baffles 21 to approach each other. The ends of the two baffles 21 approaching each other abut and cover the open end of the measuring cylinder 11, so that a sealed space is formed inside the measuring cylinder 11; the control push rod 23 moves toward the open end of the sleeve, which can push the two connecting rods 22 to move outside the support tube 12. Under the action of the limiting rod 13, the ends of the two connecting rods 22 away from the push rod 23 move away from each other, driving the two baffles 21 away from each other and leaving the open end of the measuring cylinder 11, so that the open end of the measuring cylinder 11 is opened, and the axial space directly facing the open end of the measuring cylinder 11 is unobstructed.

[0033] Further, see Figure 3 The device body 1 is also provided with a support rod 14. The outer wall of the support cylinder 12 is connected to one end of at least one support rod 14, and the other end of each support rod 14 is connected to the inner wall of the measuring cylinder 11. Through the supporting effect of the support rod 14, the support cylinder 12 can be suspended in the measuring cylinder 11 and be coaxial with the measuring cylinder 11.

[0034] Furthermore, the measuring cylinder 11 is a hard and transparent structure, so that the change of the liquid level in the measuring cylinder 11 can be observed during the measurement of the inflation amount.

[0035] Further, see Figure 3 The outer wall of the measuring cylinder 11 is provided with a scale 15 arranged along its axis. The amount of gas in the measuring cylinder 11 can be determined by the position of the scale line where the liquid level in the measuring cylinder 11 is located.

[0036] Further, see Figure 3 The end of the push rod 23 away from the open end of the measuring cylinder 11 is connected to a handle 24 so that the push rod 23 can be moved in the measuring cylinder 11 by holding the handle 24.

[0037] Give an example to illustrate the use of the flotation and mineral processing aeration volume measuring device;

[0038] S1: driving the push rod 23 to move toward the open end of the measuring cylinder 11, so as to drive the baffle 21 away from the open end of the measuring cylinder 11, and fill the inside of the measuring cylinder 11 with clean water;

[0039] S2: driving the push rod 23 to move toward the sealed end of the measuring cylinder 11, so as to drive the baffle 21 to approach and cover the open end of the measuring cylinder 11, so that the inside of the measuring cylinder 11 is sealed;

[0040] S3: Invert the open end of the measuring cylinder 11 and vertically insert it below the surface of the slurry;

[0041] S4: driving the push rod 23 to move toward the open end of the measuring cylinder 11, so as to drive the baffle 21 away from the open end of the measuring cylinder 11, and the bubbles in the slurry facing the open end of the measuring cylinder 11 rise and enter the measuring cylinder 11;

[0042] S5: The liquid level in the measuring cylinder 11 drops, and the time taken for the liquid level in the measuring cylinder 11 to drop from the first preset liquid level to the second preset liquid level is recorded.

[0043] S6: The inflation volume per unit time is calculated by using the spatial volume of the measuring cylinder 11 corresponding to the difference between the first preset liquid level and the second preset liquid level, and the recorded time.

[0044] It should be noted that, in step S2, when the push rod 23 is driven to move toward the sealed end of the measuring cylinder 11, the two connecting rods 22 move into the support cylinder 12 to drive the two baffles 21 to approach each other and move toward the open end of the measuring cylinder 11; the ends of the two baffles 21 that are close to each other contact and form a plate-like structure, covering the open end of the measuring cylinder 11, so that a sealed space is formed inside the measuring cylinder 11 to prevent leakage when the opening of the measuring cylinder 11 is inverted or vertically inserted into the slurry liquid surface.

[0045] To further illustrate, in step S4, when the push rod 23 is driven to move the open end of the measuring cylinder 11, the ends of the two connecting rods 22 connected to the baffle 21 move out of the support cylinder 12. Due to the presence of the limit rod 13, the ends of the two connecting rods 22 connected to the baffle 21 move away from each other, thereby causing the two baffles 21 to leave the space directly opposite the open end of the measuring cylinder 11, thereby preventing the bubbles rising from the open end of the measuring cylinder 11 from being blocked when the open end of the measuring cylinder 11 is below the surface of the slurry.

[0046] In this embodiment, when measuring the aeration amount of flotation beneficiation, the push rod 23 is controlled to move to open or seal the open end of the measuring cylinder 11, so as to avoid leakage and air entering when the open end of the measuring cylinder 11 is inverted or vertically inserted below the surface of the slurry; at the same time, the structure formed by the support cylinder 12, the limit rod 13, the connecting rod 22 and the push rod 23 ensures that when the open end of the measuring cylinder 11 is opened, the baffle 21 will not block the axial space corresponding to the open end of the measuring cylinder 11, thereby ensuring that the bubbles in the slurry facing the area can enter the measuring cylinder 11 normally, thereby avoiding the invalidation of the data of the aeration amount measurement.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
