Description

Technical Field

[0001] This invention relates to the field of copper matte treatment technology, and in particular to a fully automatic sump pH adjustment device with feedback. Background Technology

[0002] The copper matte produced in the smelting furnace needs to be air-quenched before proceeding to the next step. During this process, copper-containing acidic wastewater is inevitably generated. Simultaneously, waste acid produced in the air-quenching flue gas purification process is also discharged into a sump. The water in the sump, after simple pressure filtration, is reused in a clear water tank. In actual production, the pH of the wastewater in the sump drops to around 2, which is highly corrosive to equipment. Furthermore, the high content of heavy metal ions in the wastewater does not meet the discharge requirements for the next process.

[0003] Currently, the pH of pits is controlled by manually adding quicklime. However, this method is labor-intensive, causes serious environmental pollution, and results in unstable pH control. Therefore, a fully automatic pit pH adjustment device with feedback is proposed to solve these problems. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a fully automatic sump pH adjustment device with feedback, achieving rapid mixing and saving manpower.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a fully automatic sump pH adjustment device with feedback, comprising:

[0006] The pit is equipped with a level sensor for detecting water level and a pH detector for detecting pH value.

[0007] A mixing mechanism for preparing a pH adjuster for use in a pit and feeding it into the pit;

[0008] A mixing mechanism is distributed on the bottom wall of the pit, and a connecting pipe is provided on the output end of the mixing mechanism, which is connected to the mixing mechanism.

[0009] The mixing mechanism is a hollow bottle with a discharge port at the top. It includes a drive impeller located inside the connecting pipe and stirring blades connected to the drive impeller on the outside of the mixing mechanism. These blades are used to drive the drive impeller and stirring blades to rotate during the process of injecting the pH adjuster into the pit through the connecting pipe, so that the pH adjuster discharged from the discharge port can be quickly dispersed and mixed.

[0010] Furthermore, the mixing mechanism is internally provided with a telescopic sleeve and a telescopic rod for connecting the transmission impeller and the stirring blades;

[0011] The telescopic sleeve and the telescopic rod are slidably connected. A limiting groove is provided inside the telescopic sleeve, and a limiting slider corresponding to the limiting groove is provided outside the telescopic rod.

[0012] Furthermore, the bottom of the stirring blade is provided with a blocking block that is adapted to the discharge port, so that the blocking block blocks the discharge port when the stirring blade stops rotating.

[0013] Furthermore, the pH adjuster is quicklime.

[0014] Furthermore, the telescopic sleeve is provided with a grinding disc, which is used to break up clumps of pH adjuster.

[0015] Furthermore, the mixing mechanism is equipped with an addition pipe and a water inlet pipe, and the mixing mechanism is equipped with mixing blades for mixing. The mixing mechanism is equipped with a controller, and both the addition pipe and the water inlet pipe are equipped with control valves that are electrically connected to the controller.

[0016] Furthermore, a high-pressure air inlet pipe is provided on the side of the mixing mechanism. The output end of the high-pressure air inlet pipe extends into the mixing mechanism and is set perpendicular to the addition pipe. The high-pressure air inlet pipe is used to blow the material discharged from the addition pipe and make it mix with water quickly.

[0017] A fully automatic sump pH adjustment process with feedback includes the following steps:

[0018] 1) Preset the cross-sectional dimensions S of the pit;

[0019] 2) Pre-set the water ratio for quicklime slurry preparation;

[0020] 3) Preset the target pH value y for the copper matte granulation pit;

[0021] 4) Read the real-time pH value y and the sump level h;

[0022] The volume of water in the pit is L = S × h × 1000, and the amount of CaO that needs to be added is S × h (10 -x -10 -y 28, in kg.

[0023] 5) After mixing the quicklime thoroughly, pour it into the pit;

[0024] 6) After 30 minutes in the static pit, the pH value was measured.

[0025] The beneficial effects of this invention are reflected in:

[0026] This invention utilizes the measurement results from a pH detector and a liquid level sensor, and calculates the result using the formula S×h(10) -x -10 -yThe amount of quicklime added is obtained by feeding clean water through the water inlet pipe. The quicklime feeding screw mixes inside the mixing mechanism. During the mixing process, the quicklime is slurried and then transported to the pit through the connecting pipe. It is then quickly stirred by the mixing mechanism, which can effectively control the pH of the pit, reduce the wear and tear of acidic wastewater on the granulation equipment, and reduce the labor intensity of workers.

[0040] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0041] Please see Figure 1-7 This invention discloses a fully automatic sump pH adjustment device with feedback, comprising:

[0042] Pit 01, wherein a liquid level sensor 02 for detecting water level height and a pH detector 03 for detecting pH value are provided in the pit 01;

[0043] Mixing mechanism 1, the mixing mechanism 1 being used to prepare a pH adjuster according to the pit 01 and to feed it into the pit 01;

[0044] A mixing mechanism 3 is distributed on the bottom wall of the pit 01. A connecting pipe 4 is provided on the output end of the mixing mechanism 1, and the connecting pipe 4 is connected to the mixing mechanism 3.

[0045] The mixing mechanism 3 is a hollow bottle. The top of the mixing mechanism 3 is provided with a discharge port 36. It includes a transmission impeller 31 located inside the connecting pipe 4. The outside of the mixing mechanism 3 is provided with stirring blades 32 that are connected to the transmission impeller 31. During the process of injecting the pH adjuster into the pit 01 through the connecting pipe 4, the transmission impeller 31 and stirring blades 32 are driven to rotate, so that the pH adjuster discharged from the discharge port 36 can be quickly dispersed and mixed.

[0046] In this embodiment, with the above-described structural setup, the device, during use, can determine the total water volume in pit 01 by using the pH detector 03, the liquid level sensor 02, and the area of ​​the preset pit 01. Based on the current pH value of the water volume, the total water volume is calculated using the formula S×h(10) / 2π. -x -10 -y )28 can be used to determine the amount of CaO to be added. Then, based on this amount, the ratio of quicklime slurry water is adjusted and injected into the mixing mechanism 1. After mixing, it is injected into the homogenizing mechanism 3 through the connecting pipe 4. The homogenizing mechanism 3 quickly distributes the quicklime in the pit 01 to achieve homogenization. Specifically, during the discharge process, the quicklime mixture will drive the transmission impeller 31 and the stirring blade 32 to rotate. When the quicklime mixture is discharged from the discharge port 36, the stirring blade 32 can disturb the discharged quicklime mixture to achieve the purpose of rapid homogenization.

[0047] The second embodiment that needs to be explained is that the mixing mechanism 3 is provided with a telescopic sleeve 33 and a telescopic rod 34 for connecting the transmission impeller 31 and the stirring blade 32.

[0048] The telescopic sleeve 33 and the telescopic rod 34 are slidably connected. The telescopic sleeve 33 is provided with a limiting groove, and the telescopic rod 34 is provided with a limiting slider corresponding to the limiting groove.

[0049] Meanwhile, the bottom of the stirring blade 32 is provided with a blocking block 321 that is adapted to the discharge port 36, so that the blocking block 321 blocks the discharge port 36 when the stirring blade 32 stops rotating.

[0050] With the settings in the above embodiments, when the equipment is in use, through the telescopic sleeve 33 and telescopic rod 34, during the sedimentation process in the pit 01, the stirring blade 32 is pressed down under the action of gravity, and the discharge port 36 is blocked by the blocking block 321 to prevent the sediment from entering the connecting pipe 4 through the discharge port 36 and causing blockage during the sedimentation process. When the quicklime mixture needs to be injected, the pressure inside the discharge port 36 is greater than the gravity of the stirring blade 32 and the gravity of the sediment at the top.

[0051] It should be noted that the pH adjuster is quicklime.

[0052] In this application, it should be further explained that the telescopic sleeve 34 is provided with a grinding plate 35, which is used to break up the clumps of pH adjuster. With the above-mentioned structural arrangement, the grinding plate 35 can break up the clumps of quicklime during the rotation of the telescopic sleeve 34, and then discharge it through the discharge port 36.

[0053] In embodiment 3, the mixing mechanism 1 is provided with an addition pipe 11 and a water inlet pipe 12. The mixing mechanism 1 is provided with a mixing blade 13 for mixing. The mixing mechanism 1 is provided with a controller. The addition pipe 11 and the water inlet pipe 12 are both provided with control valves electrically connected to the controller. The addition pipe 11 can quantitatively feed the lime slurry into the lime slurry device through a weightless spiral. It should be noted that the mixing mechanism 1 is also provided with a mixing motor for driving the mixing blade 13 to rotate.

[0054] Furthermore, the mixing mechanism 1 is provided with a high-pressure air inlet pipe 2 on its side. The output end of the high-pressure air inlet pipe 2 extends into the mixing mechanism 1 and is set perpendicular to the addition pipe 11. The high-pressure air inlet pipe 2 is used to blow the material discharged from the addition pipe 11 and make it mix with water quickly.

[0055] With the configuration described in the above embodiments, the material discharged from the addition pipe 11 can be sprayed out through the high-pressure air inlet pipe 2 and mixed with the water discharged from the water inlet pipe 12 in the mixing mechanism 1. Then, the mixing blades 13 are driven to rotate at high speed. At the same time, the pressure inside the mixing mechanism 1 can be increased through the high-pressure air inlet pipe 2, so that the spraying range is larger and faster during the discharge process at the discharge port 36. The mixture is quickly mixed by the surge of gas, further stirring the mixture to achieve full mixing, and finally discharged.

[0056] like Figure 1 As shown, a fully automatic sump pH adjustment process with feedback includes the following steps:

[0057] 1) Preset the cross-sectional dimension S of pit 01;

[0058] 2) Pre-set the water ratio for quicklime slurry preparation;

[0059] 3) Preset the target pH value y for the copper matte granulation pit;

[0060] 4) Read the real-time pH value y and the sump level h;

[0061] The volume of water in the pit is L = S × h × 1000, and the amount of CaO that needs to be added is S × h (10 -x -10 -y 28, in kg.

[0062] 5) After mixing the quicklime thoroughly, pour it into pit 01;

[0063] 6) After 30 minutes in the static pit 01, the pH value was tested.

[0064] This invention utilizes the measurement results from pH detector 03 and liquid level sensor 02, and calculates the result using the formula S×h(10) -x -10 -y The amount of quicklime added is obtained by feeding clean water through the water inlet pipe 12. The quicklime feeding screw mixes inside the mixing mechanism. During the mixing process, the quicklime is slurried and then transported to the pit 01 through the connecting pipe 4. This can effectively control the pH of the pit, reduce the wear and tear of acidic sewage on the granulation equipment, and reduce the labor intensity of workers.

[0065] It should be noted that if the embodiments of the present invention involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0066] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. If the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0067] Additionally, "multiple" refers to two or more.

[0068] 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 within the protection scope of the present invention.
