Description

Technical Field

[0001] This invention relates to the field of sedimentation equipment technology, and in particular to a sedimentation device for treating copper smelting slag wastewater. Background Technology

[0002] The main pollutants in copper production wastewater include heavy metals (such as copper, nickel, lead, and zinc), acids and alkalis, suspended solids, and organic matter. These pollutants may originate from ore mining and processing, copper extraction and refining processes, and the manufacture of copper products.

[0003] In industrial applications, water costs necessitate the long-term recycling of some water. However, existing technologies for treating copper production wastewater are typically complex, requiring multiple treatment techniques for different types of pollutants, such as filtration pretreatment and precipitation with chemical agents. In the filtration stage, the filter screen needs to be rinsed after a certain filtration cycle. Existing surface cleaning mechanisms are complex and require downtime, delaying equipment operation and indicating room for improvement. Therefore, a sedimentation device for copper smelting slag wastewater treatment is proposed to address these issues. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a sedimentation device for treating copper smelting slag wastewater.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution: a settling device for treating copper smelting slag wastewater, comprising:

[0006] The filter section, buffer section, and sedimentation section are arranged from left to right;

[0007] The filter section is equipped with a rotatable filter drum, and a pump is installed inside the filter drum. The filter drum is used to filter the sewage entering from the inlet pipe, and the pump sends the filtered water to the buffer section.

[0008] The filter roller includes a cylindrical filter screen with multiple partitions on it. A cleaning scraper that can slide along the cylindrical filter screen is provided between the partitions. The cleaning scraper is used to clean the surface of the cylindrical filter screen.

[0009] The filter roller also includes a drive unit for driving the cylindrical filter screen to rotate, and a magnetic suction part fixedly disposed on the filter section. The cleaning scraper is provided with magnetic metal on the side near the magnetic suction part, so that when the cleaning scraper rotates with the cylindrical filter screen and passes through the magnetic suction part, it is attracted and fixed by the magnetic suction part, so that the cleaning scraper and the cylindrical filter screen rotate relative to each other, thereby achieving cleaning of the surface of the cylindrical filter screen.

[0010] Furthermore, the filter section is provided with a water inlet pipe, and the sedimentation section is provided with a drain outlet.

[0011] Furthermore, the cylindrical filter screen is provided with side baffles on both sides, and the side baffles and the multiple partitions divide the surface of the cylindrical filter screen into multiple filter chambers;

[0012] The cylindrical filter screen has a collection section inside, which is used to receive the filtrate filtered out by the cylindrical filter screen above it;

[0013] The side baffle is provided with a limiting groove corresponding to the cleaning scraper, and the magnetic suction part is located directly below the drive unit.

[0014] Furthermore, the filtration section also includes a slag discharge mechanism disposed below the filter drum. The slag discharge mechanism is a conveying mechanism used to receive and discharge the falling filter slag.

[0015] Furthermore, the buffer section is provided with a horizontally arranged receiving plate and a vertically arranged isolation plate;

[0016] The receiving plate is positioned opposite to the output end of the pump, and the top of the receiving plate is provided with an inclined surface. The receiving plate is used to receive the water flow discharged by the pump.

[0017] The isolation plate is located below the receiving plate. There are two sets of isolation plates arranged alternately to allow the filtered water to overflow into the settling section.

[0018] Furthermore, an inlet is provided between the buffer section and the settling section, and an adjustable plate is provided inside the inlet. Multiple sets of drain pipes extending into the settling section are provided on the adjustable plate.

[0019] The settling section is equipped with a turbidity analyzer to identify the height of the sediment;

[0020] The inlet is equipped with a telescopic groove corresponding to the regulating plate, and the settling part is equipped with a telescopic push rod for driving the regulating plate to rise and fall.

[0021] Furthermore, the sedimentation section is equipped with a controller, which is electrically connected to a turbidity analyzer and a telescopic push rod. The controller is used to adjust the height of the drain pipe according to the height of the precipitate by means of the telescopic push rod so that it is located at the stratification point between the supernatant and the precipitate.

[0022] Furthermore, the bottom of the drain pipe is provided with multiple sets of drainage holes, and a diffuser is provided below the drainage holes. The diffuser is used to diffuse the filtered liquid discharged from the drainage holes in a horizontal direction.

[0023] The beneficial effects of this invention are reflected in:

[0024] In this invention, wastewater from the inlet pipe continuously flows into the filter chamber located at the top of the filter drum. It then undergoes initial screening through a cylindrical filter screen, separating large metal particles and floating debris. As the filter drum rotates, the wastewater falls onto a slag discharge mechanism for collection and further processing. The equipment uses feedback from a turbidity analyzer to determine the stratification point between the supernatant and sediment. A controller and telescopic push rod adjust the height of the drain pipe to position it at the center of the supernatant-sediment stratification point. This ensures that fine impurities in the water sink while the clear liquid floats during drainage, preventing disturbance of the already settled supernatant and avoiding prolonged sedimentation time.

[0037] 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.

[0038] Please see Figure 1-6 This invention discloses a settling device for treating copper smelting slag wastewater, comprising:

[0039] The filter section 1, buffer section 2, and sedimentation section 3 are arranged from left to right;

[0040] The filter section 1 is equipped with a rotatable filter drum 11. A pump 12 is installed inside the filter section 1 and inside the filter drum 11. The filter drum 11 is used to filter the sewage entering from the inlet pipe 4 and to send the filtered water to the buffer section 2 through the pump 12.

[0041] The filter roller 11 includes a cylindrical filter screen 111, on which a plurality of partitions 112 are provided, and a cleaning scraper 114 that can slide along the cylindrical filter screen 111 is provided between the plurality of partitions 112. The cleaning scraper 114 is used to clean the surface of the cylindrical filter screen 111.

[0042] The filter roller 11 also includes a drive unit 115 for driving the cylindrical filter screen 111 to rotate, and a magnetic suction part 113 fixedly disposed on the filter section 1. The cleaning scraper 114 is provided with magnetic metal on the side near the magnetic suction part 113, so that when the cleaning scraper 114 rotates with the cylindrical filter screen 111 and passes through the magnetic suction part 113, it is attracted and fixed by the magnetic suction part 113, so that the cleaning scraper 114 and the cylindrical filter screen 111 rotate relative to each other, thereby cleaning the surface of the cylindrical filter screen 111.

[0043] It should be noted that the filter section 1 is provided with a water inlet pipe 4, and the sedimentation section 3 is provided with a drain outlet 5.

[0044] like Figure 5 As shown, the cylindrical filter screen 111 has side baffles on both sides, and the side baffles and the multiple partitions 112 divide the surface of the cylindrical filter screen 111 into multiple filter chambers;

[0045] The cylindrical filter screen 111 is provided with a collection part 116 inside, which is used to receive the filtrate filtered out by the cylindrical filter screen 111 above it.

[0046] The side baffle is provided with a limiting groove 117 corresponding to the cleaning scraper 114, and the magnetic suction part 113 is located directly below the drive unit 115.

[0047] Specifically, the filter section 1 also includes a slag discharge mechanism 13 disposed below the filter drum 11. The slag discharge mechanism 13 is a conveying mechanism used to receive and discharge the falling filter slag.

[0048] When in use, the wastewater inside the inlet pipe 4 can continuously fall into the filter chamber located at the top of the filter drum 11 through the above-mentioned structural setting. Then, it is filtered by the cylindrical filter screen 111 to perform initial screening, screening out large metal particles and floating debris in the wastewater. Then, as the filter drum 11 rotates, it falls onto the slag discharge mechanism 13 for collection and subsequent treatment, avoiding the problem of rapid accumulation of sediment and the need for frequent treatment.

[0049] To address debris adhering to the cylindrical filter screen 111, a movable cleaning scraper 114 with a magnetic metal end is provided. When the scraper passes through the magnetic suction part 113, it is attracted by the magnetic suction part 113 and cannot continue to rotate with the cylindrical filter screen 111. At this time, the cylindrical filter screen 111 rotates, which causes relative rotation with the cleaning scraper 114. Thus, the cleaning scraper 114 scrapes away the debris adhering to the cylindrical filter screen 111. As the cylindrical filter screen 111 continues to rotate, the partition 112 pushes the cleaning scraper 114 to separate from the magnetic suction part 113.

[0050] It should be noted that as the cylindrical filter screen 111 rotates, when the cleaning scraper 114 is located on the side, it will fall to the other side of the filter chamber under the action of gravity, so that the filter chamber can be cleaned later when passing through the magnetic suction part 113. Meanwhile, if... Figure 6 As shown, the magnetic suction part 113 and the cleaning scraper 114 are installed in a staggered manner. When the cleaning scraper 114 passes through the magnetic suction part 113, it can be attracted by the magnetic suction part 113 and move closer to the cylindrical filter screen 111, thereby increasing the scraping efficiency of the cleaning scraper 114 on the surface of the cylindrical filter screen 111.

[0051] In this embodiment, as Figure 2 As shown, the buffer section 2 is provided with a horizontally arranged receiving plate 21 and a vertically arranged isolation plate 22.

[0052] The receiving plate 21 is positioned opposite to the output end of the pump 12. The top of the receiving plate 21 is provided with an inclined surface. The receiving plate 21 is used to receive the water flow discharged by the pump 12. After the water flow impacts, it falls along the receiving plate 21 and gradually overflows into the subsequent isolation plate 22 to avoid excessive water flow and disturb the sediment that has already settled in the sedimentation section 3.

[0053] The isolation plate 22 is disposed below the receiving plate 21. There are two sets of isolation plates 22 arranged alternately to allow the filtered water to overflow into the settling section 3.

[0054] It should be noted that, as Figure 2 As shown, a water inlet is provided between the buffer section 2 and the settling section 3. An adjustable plate 32 that can be adjusted up and down is provided in the water inlet. Multiple sets of drain pipes 31 extending into the settling section 3 are provided on the adjustable plate 32.

[0055] The sedimentation section 3 is equipped with a turbidity analyzer 35 to identify the height of the sediment;

[0056] The inlet is provided with a telescopic groove 33 corresponding to the adjusting plate 32, and the settling part 3 is provided with a telescopic push rod 34 for driving the adjusting plate 32 to rise and fall.

[0057] Furthermore, the sedimentation section 3 is equipped with a controller, which is electrically connected to the turbidity analyzer 35 and the telescopic push rod 34. The controller is used to adjust the height of the drain pipe 31 according to the height of the precipitate by using the telescopic push rod 34 so that it is located at the stratification point between the supernatant and the precipitate.

[0058] With the above settings, the device can obtain the stratification point between the supernatant and the precipitate based on the feedback from the turbidity analyzer 35, and adjust the height of the drain pipe 31 through the controller and the telescopic push rod 34 so that it is located in the middle of the stratification point between the supernatant and the precipitate. This is to filter out small impurities in the water during the drainage process so that the clear liquid floats to the top, thus avoiding disturbing the already settled supernatant during the drainage process and prolonging the sedimentation time.

[0059] Finally, it should be noted that the bottom of the drain pipe 31 is provided with multiple sets of drain holes 311, and a diffuser plate 312 is provided below the drain holes 311. The diffuser plate 312 is used to make the filtered liquid discharged from the drain holes 311 diffuse in the horizontal direction to avoid direct impact from the water flow.

[0060] 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.

[0061] 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.

[0062] Additionally, "multiple" refers to two or more.

[0063] 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.
