Description

Technical Field

[0001] This invention relates to the field of wastewater treatment equipment technology, specifically a multi-stage wastewater treatment mechanism for molybdenum concentrate metallurgy. Background Technology

[0002] The metallurgical process of molybdenum concentrate typically includes multiple steps such as roasting, leaching, extraction, precipitation, and washing. During the operation of these steps, a large amount of complex industrial wastewater is generated. This type of wastewater generally contains high concentrations of heavy metal ions (such as molybdenum ions, iron ions, copper ions, etc.), acid and alkali residues, suspended particulate matter, and some organic reagents. It is characterized by high pollution load, large fluctuations in composition, and great difficulty in treatment. If it is discharged directly without effective treatment, it can easily cause serious impacts on the aquatic ecological environment and soil safety.

[0003] Traditional treatment processes often employ mechanical stirring, gravity sedimentation, or simple filtration for solid-liquid separation and reagent mixing. Mechanical stirring relies on forced shearing by blades to generate bubbles, but the uneven distribution of bubbles makes it difficult to achieve sufficient mixing of reagents and water, easily leading to excessive local reactions or reagent waste. Solid particle sedimentation relies on gravity alone, and particles tend to accumulate on the filter screen or slag discharge pipe, causing blockages and affecting continuous operation efficiency. Therefore, this application proposes a multi-stage treatment mechanism for wastewater from molybdenum concentrate metallurgy. Summary of the Invention

[0004] The purpose of this invention is to provide a multi-stage wastewater treatment mechanism for molybdenum concentrate metallurgy, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a multi-stage wastewater treatment mechanism for molybdenum concentrate metallurgy, comprising a support platform, a purification tank disposed inside the support platform, a liquid delivery pipe fixedly installed inside the support platform, the output end of the liquid delivery pipe being connected to the upper end of the purification tank, a liquid extraction pipe fixedly installed inside the support platform, the input end of the liquid extraction pipe being connected to the bottom end of the purification tank, multiple strip-shaped holes being opened on the inner sidewall surface of the purification tank, a support shell being fixedly installed inside each strip-shaped hole, a buffer plate being fixedly installed between two adjacent support shells, a water-blocking block being fixedly installed on the surface of the buffer plate, a collecting cylinder being disposed between the water-blocking block and the buffer plate, a slag discharge device being disposed inside the collecting cylinder, an installation groove being opened on the surface of the water-blocking block, an isolation shell being fixedly installed inside the installation groove, and a mixing device being disposed inside the isolation shell.

[0006] As a further embodiment of the present invention, the slag discharge device includes a slag discharge pipe, which is rotatably installed inside the collecting cylinder. The pipe wall surface of the slag discharge pipe is provided with a plurality of rectangular holes, which are used to allow solid impurities flowing with the wastewater to pass through the pipe wall and enter the interior of the slag discharge pipe. An air compressor is fixedly installed at the inner end of the slag discharge pipe, and a buffer pipe is fixedly installed on the surface of the air compressor, and the buffer pipe is located inside the slag discharge pipe.

[0007] As a further embodiment of the present invention, a gas guide pipe is provided inside the slag discharge pipe. The gas guide pipe is fixedly connected to the buffer pipe. Multiple guide spiral blades are fixedly installed on the outer surface of the gas guide pipe. The multiple guide spiral blades are used to axially push the solid impurities entering the pipe when the slag discharge pipe rotates, so that the impurities can be smoothly discharged along the slag discharge pipe, avoiding solid accumulation and blockage, ensuring the continuity and stability of the slag discharge process, and working in conjunction with gas transportation to improve slag discharge efficiency.

[0008] As a further embodiment of the present invention, a central rod is axially inserted inside the air compressor, and an air guide groove is formed on the outer surface of the central rod along the axial direction. The central rod and the air compressor are connected by an auxiliary spring. The auxiliary spring is used to apply a restoring force to the central rod, so that the solid impurities in the slag discharge pipe remain in a suspended state for a short time during the slag discharge process, thereby reducing the resistance to impurity accumulation, improving the slag discharge efficiency, and ensuring that the system can operate repeatedly and stably.

[0009] As a further embodiment of the present invention, a pressure relief cover is fixedly connected to the end of the central rod away from the buffer tube. The pressure relief cover is used to form an opening and closing cooperation with the air compressor under air pressure. The surface of the pressure relief cover is evenly provided with multiple vent holes, which form a controllable opening and closing structure with the air compressor through the vent holes. Under air pressure, the channel is opened to introduce gas, so that the solid impurities in the slag discharge pipe are kept in a suspended state for a short time, reducing the accumulation resistance. After the air pressure disappears, the pressure relief cover closes to ensure the sealing of the pipe, thereby improving the slag discharge efficiency and system stability.

[0010] As a further embodiment of the present invention, the mixing device includes multiple mixing tubes, which are fixedly installed at the inner end of the isolation shell and spaced apart along the wastewater flow direction. The upper end of each mixing tube has a rectangular through hole, and a passive blade is rotatably installed at the upper end of each mixing tube. The blade is driven to swing by the natural flow of wastewater, thereby achieving continuous stirring and thorough mixing of the agent. This avoids the problem of uneven agent distribution or uneven bubble generation caused by the forced shearing of traditional mechanical stirring, thus improving wastewater purification efficiency and mixing uniformity.

[0011] As a further embodiment of the present invention, two sealing sleeves are fixedly installed at the inner end of the mixing tube, the two sealing sleeves are spaced apart along the axial direction of the mixing tube, a spiral rod is inserted inside the mixing tube, a sealing cover is slidably installed at the upper end of the mixing tube, the sealing cover is used to cover the space between the two sealing sleeves, and two limiting blocks are fixedly installed at the upper end of the sealing cover, the passive blade is disposed between the two limiting blocks.

[0012] As a further embodiment of the present invention, a plurality of pressurizing pipes are fixedly installed on the surface of the supporting shell. The pressurizing pipes are rotatably connected to the corresponding slag discharge pipes. The pressurizing pipes correspond to the air compressor. A connecting ring is sleeved on the outer surface of the pressurizing pipe. A movable gear is rotatably installed on the surface of the connecting ring, and the movable gear is slidably sleeved on the outer surface of the slag discharge pipe.

[0013] As a further embodiment of the present invention, a drive motor is fixedly installed on the inner end of the support shell by bolts, a drive gear is fixedly installed on the output end of the drive motor, a connecting seat is fixedly installed on the surface of the support shell, a connecting pipe is rotatably installed on the surface of the connecting seat, a driven gear is fixedly installed on the outer surface of the connecting pipe, and the driven gear meshes with the drive gear.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The multi-stage wastewater treatment mechanism of the present invention, by setting a stepped buffer plate and water-blocking block structure in the purification tank, enables the molybdenum concentrate metallurgical wastewater to form a step-by-step flow state under the action of gravity. Large solid impurities and metal particles in the wastewater can be effectively retained between the buffer plate and the water-blocking block and concentrated into the slag discharge pipe, thereby achieving preliminary solid-liquid separation and reducing the load on subsequent treatment units. 2. The multi-stage wastewater treatment mechanism of the present invention, by setting up a pressurizing pipe, an air compressor and an air guiding structure linked with the slag discharge pipe, directs gas into the pipe during the slag discharge process, so that the solid impurities accumulated in the slag discharge pipe are in a temporary suspended or loose state, thereby reducing the slag discharge resistance and avoiding slag discharge pipe blockage. 3. The multi-stage wastewater treatment mechanism of the present invention utilizes the turbulent conditions formed by the falling and churning of wastewater in the stepped structure to drive the passive blades to swing. The passive blades also drive the sealing cover to move back and forth, so that the spiral rod in the mixing pipe is intermittently exposed to the wastewater. By utilizing the shear force generated by the falling, the reagent and wastewater can be quickly mixed at a microscopic level. At the same time, the "wave-like" flow ensures the continuous dilution and uniform distribution of the reagent, avoiding the local over-reaction or reagent waste commonly found in traditional dosing tanks. 4. The multi-stage wastewater treatment mechanism of the present invention forms a thin layer of wave flow by the wastewater falling through the stepped buffer plate and water-blocking block structure, which spontaneously draws in air and synchronizes with the mixing process, so as to achieve uniform distribution of microbubbles. The buoyancy of the bubbles can guide fine particles to migrate to the edge of the filter plate, reduce the risk of filter screen clogging while reacting, and improve the stability of continuous operation of the device.

[0018] 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 some embodiments of the present invention, and not all embodiments. 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.

[0019] Example 1: Please refer to Figures 1-3 A multi-stage wastewater treatment mechanism for molybdenum concentrate metallurgy includes a support platform 1. The support platform 1 is equipped with a purification tank 4, which is used to perform multi-stage filtration and purification treatment on the wastewater generated during the molybdenum concentrate metallurgy process. A liquid delivery pipe 3 is fixedly installed inside the support platform 1 by a bracket. The output end of the liquid delivery pipe 3 is connected to the upper end of the purification tank 4 so that the wastewater to be treated enters the purification tank 4 from top to bottom. A liquid extraction pipe 2 is also fixedly installed inside the support platform 1 by a bracket. The input end of the liquid extraction pipe 2 is connected to the bottom end of the purification tank 4 so as to export the purified wastewater after completing the filtration and sedimentation treatment, thereby forming a stable wastewater treatment flow path. Multiple strip-shaped holes are formed on the inner wall surface of the purification tank 4. These holes are arranged in a stepped and inclined manner along the height of the purification tank 4 to guide the wastewater to flow down the tank in stages. A support shell 101 is fixedly installed inside each strip-shaped hole. A buffer plate 202 is fixedly installed between two adjacent support shells 101. The buffer plate 202 is used to reduce the downward flow velocity of the wastewater and form a temporary residence area. A water-blocking block 214 is fixedly installed on the surface of the buffer plate 202. A retention space for heavy particles is formed between the water-blocking block 214 and the buffer plate 202. When the wastewater flows along the surface of the buffer plate 202, the metal particles and high-density solid impurities mixed in the wastewater are deposited and retained between the water-blocking block 214 and the buffer plate 202 under the action of gravity (the buffer plate 202 is arranged as follows). Figure 3 As shown), the inner end of the purification box 4 is fixedly installed with a guide plate 201, which is used to guide the wastewater to the correct position of the buffer plate 202 so that it flows down. The number of buffer plates 202 is not unique and can be stacked continuously to maximize the efficiency of single treatment and avoid the need for a single batch to repeatedly pass through the buffer plate 202. like Figures 2-4As shown, a collecting cylinder 203 is provided between the water-blocking block 214 and the buffer plate 202. The collecting cylinder 203 is used to collect the solid impurities and metal particles deposited after being intercepted by the water-blocking block 214. A slag discharge device is provided inside the collecting cylinder 203. An installation groove is opened on the surface of the water-blocking block 214. An isolation shell 302 is fixedly installed inside the installation groove. A mixing device is provided inside the isolation shell 302. The mixing device is used to add purification agents to the wastewater as the wastewater flows step by step along the stepped structure. The agents are fully mixed with the wastewater during the process of the wastewater falling, impacting and changing the flow direction. Under the guiding effect of the stepped structure, the wastewater falls and tumbles multiple times with the cooperation of the buffer plate 202 and the water-blocking block 214, so that the water body presents a discontinuous flow state, thereby significantly increasing the contact area between the water body and the surrounding air. Oxygen from the air is drawn into the wastewater during the churning of the water, creating a spontaneous aeration environment that does not require additional aeration equipment. This promotes the oxidation of reducing pollutants in the molybdenum concentrate metallurgical wastewater.

[0020] like Figures 4-6 As shown, the slag discharge device includes a slag discharge pipe 204, which is rotatably installed inside the collecting cylinder 203. The side of the collecting cylinder 203 away from the water-blocking block 214 is an open structure, so that after the wastewater flows through the retention area formed by the water-blocking block 214 and the buffer plate 202, the solid impurities and metal particles separated from the wastewater fall into the collecting cylinder 203 under the action of gravity and converge towards the slag discharge pipe 204. The surface of the slag discharge pipe 204 is provided with multiple rectangular holes, which are used to allow the solid impurities flowing with the wastewater to pass through the pipe wall and enter the interior of the slag discharge pipe 204. The inner end of the slag discharge pipe 204 is fixedly installed with an air compressor 208, and the surface of the air compressor 208 is fixedly installed with a buffer pipe 207, which is located inside the slag discharge pipe 204. A gas guide pipe 206 is installed inside the slag discharge pipe 204. The gas guide pipe 206 is fixedly connected to the buffer pipe 207. Multiple guide spiral blades 205 are fixedly installed on the outer surface of the gas guide pipe 206. The multiple guide spiral blades 205 are used to axially push the solid impurities entering the pipe when the slag discharge pipe 204 rotates. The surface of the gas guide pipe 206 has multiple air holes. When the amount of solid impurities accumulated inside the slag discharge pipe 204 is large and it is difficult to discharge them in time by mechanical rotation of the guide spiral blades 205 alone, gas is sprayed into the slag discharge pipe 204 through the air holes on the surface of the gas guide pipe 206. This causes the solid impurities inside the pipe to be in a temporary suspended or loose state, thereby reducing their accumulation resistance. Subsequently, under the continuous rotation of the guide spiral blades 205, the solid impurities inside the slag discharge pipe 204 can be smoothly transported and discharged, achieving efficient cleaning of solid impurities in the collecting cylinder 203.

[0021] Example 2: Please refer to Figure 7A multi-stage wastewater treatment mechanism for molybdenum concentrate metallurgy, based on Embodiment 1, has a central rod 211 axially inserted inside the air compressor 208, and an air guide groove 213 axially formed on the outer surface of the central rod 211, with the air guide groove 213 located in the middle region of the central rod 211. The central rod 211 and the air compressor 208 are connected by an auxiliary spring 212, which is used to apply a restoring force to the central rod 211. A pressure relief cover 209 is fixedly connected to the end of the central rod 211 away from the buffer tube 207. The pressure relief cover 209 is used to form an opening and closing cooperation with the air cylinder 208 under air pressure. The surface of the pressure relief cover 209 is evenly provided with multiple vent holes 210. When the air pressure inside the air cylinder 208 increases and pushes the pressure relief cover 209 to move axially, the vent holes 210 on the surface of the pressure relief cover 209 enter the inner cavity area of ​​the air cylinder 208, so that gas can enter the interior of the air cylinder 208 through the vent holes 210. At the same time, the central rod 211 moves synchronously with the pressure relief cover 209, so that the air guide groove 213 on the surface of the central rod 211 forms a communication channel with the buffer tube 207 and the inner cavity of the air cylinder 208, thereby realizing the introduction of gas from the buffer tube 207 into the interior of the air cylinder 208.

[0022] like Figure 4 , Figure 5 , Figure 8 As shown, the mixing device includes multiple mixing pipes 301, which are fixedly installed at the inner end of the isolation shell 302 and spaced apart along the wastewater flow direction. A rectangular through hole is opened at the upper end of the mixing pipe 301, and a passive blade 303 is rotatably installed at the upper end of the mixing pipe 301. After the wastewater is guided by the water baffle 214, it enters the isolation shell 302 area. Due to the change in the flow channel cross section, the water flow generates turbulence, and the tail end of the passive blade 303 swings under the action of turbulence. Two sealing sleeves 305 are fixedly installed at the inner end of the mixing pipe 301. The two sealing sleeves 305 are spaced apart along the axial direction of the mixing pipe 301. A spiral rod 306 is inserted inside the mixing pipe 301 for conveying the reagents required for wastewater purification. A sealing cover 307 is slidably installed at the upper end of the mixing pipe 301. The sealing cover 307 is used to cover the space between the two sealing sleeves 305. Two limiting blocks are fixedly installed at the upper end of the sealing cover 307. A passive blade 303 is disposed between the two limiting blocks. Furthermore, a scraper block 304 is fixedly installed at the inner end of the mixing pipe 301. The scraper block 304 is used to scrape off the agent embedded or attached to the spiral groove on the surface of the spiral rod 306 to prevent the agent from stagnating and affecting the conveying and mixing efficiency. When multiple mixing pipes 301 are set in the isolation shell 302, the size or scraping intensity of the scraper block 304 in different mixing pipes 301 are different in sequence, so that the agent is scraped off and released into the wastewater step by step when passing through each mixing pipe 301 in the direction of wastewater flow. This achieves the segmented release and uniform mixing of the agent, and enhances the reaction stability and purification effect in the multi-stage treatment process of molybdenum concentrate metallurgical wastewater.

[0023] like Figure 4 , Figure 5 , Figure 7 , Figure 9 As shown, multiple pressurizing pipes 102 are fixedly installed on the surface of the support shell 101. On the other side of the support shell 101, which is corresponding to each pressurizing pipe 102, multiple slag discharge pipes 215 are fixedly installed. The pressurizing pipes 102 are rotatably connected to the corresponding slag discharge pipes 204. The pressurizing pipes 102 correspond to the air compressor 208. The slag discharge pipes 215 are rotatably connected to the output end of the slag discharge pipes 204, thus forming a structure in which pressurization and slag discharge are mutually coordinated. Specifically, a solenoid valve is installed inside the pressurizing pipe 102. The solenoid valve is used to control the opening and closing of the pressurizing pipe 102 to achieve controllable adjustment of the air supply process of the air compressor 208. A dynamic sensing device is installed at the inner end of the support shell 101 to detect the movement state of the movable gear 105. When the movable gear 105 moves, the solenoid valve opens and remains open for a period of time, and then closes. It is worth noting that the solenoid valve and the dynamic sensing device are existing mature technologies. The specific working principle and model are well known to those skilled in the art and will not be described in detail here. A connecting ring 106 is sleeved on the outer surface of the pressurizing pipe 102. The movable gear 105 is rotatably mounted on the surface of the connecting ring 106, and the movable gear 105 is slidably sleeved on the outer surface of the slag discharge pipe 204. A drive motor 109 is fixedly installed on the inner end of the support shell 101 by bolts. A drive gear 112 is fixedly installed on the output end of the drive motor 109. After the movable gear 105 moves away from the pressurization pipe 102, the movable gear 105 meshes with the drive gear 112. A connecting seat 104 is fixedly installed on the surface of the support shell 101. A connecting pipe 110 is rotatably installed on the surface of the connecting seat 104. A screw rod 306 is fixedly connected to the connecting pipe 110, and the end of the screw rod 306 extends into the interior of the connecting seat 104. A medicine bottle 103 for storing and providing purification agents is detachably installed on the upper end of the connecting seat 104. A passive gear 111 is fixedly installed on the outer surface of the connecting pipe 110. The passive gear 111 meshes with the drive gear 112 and can synchronously drive the screw rod 306 to rotate when the drive motor 109 is working, so as to realize the quantitative delivery of the medicine. Specifically, a movable plate 107 is fixedly installed on the surface of the connecting ring 106, and an extension rod 108 is fixedly installed on the side of the movable plate 107 near the connecting seat 104. A pressing ring 113 is sleeved on the inner end of the connecting seat 104. The pressing ring 113 is connected to the connecting seat 104 by a return spring 115. When the medicine bottle 103 is installed above the connecting seat 104, the medicine bottle 103 pushes the pressing ring 113 downward under its own weight. The bottom end of the pressure ring 113 is fixedly equipped with a guide plate 114. The surface of the guide plate 114 is provided with a guide groove. The end of the extension rod 108 passes through the guide groove. When the pressure ring 113 moves downward, the guide plate 114 and the extension rod 108 drive the movable plate 107 and the movable gear 105 to move synchronously, so that the movable gear 105 disengages from the meshing state with the drive gear 112, thereby pausing the drive of the slag discharge pipe 204 and the screw rod 306.

[0024] The working principle of this invention is: In use, the medicine bottle 103 is installed on the connecting seat 104 in sequence. Under its own weight, the medicine bottle 103 pushes the pressure ring 113 to move downward. When the pressure ring 113 moves downward, the guide plate 114 and the extension rod 108 drive the movable plate 107 and the movable gear 105 to move synchronously, so that the movable gear 105 disengages from the meshing state with the driving gear 112. At this time, the output end of the drive motor 109 drives the connecting pipe 110 to rotate through the active gear 112. At this time, the screw rod 306 transports the medicine inside the medicine bottle 103 to the inside of the mixing pipe 301. As the liquid delivery pipe 3 continuously transports the molybdenum concentrate wastewater to the inside of the purification box 4, it then flows from the surface of the buffer plate 202. Larger particles of solids in the wastewater are blocked and retained between the water baffle 214 and the buffer plate 202 during the flow. Then, under the action of the water flow, they are introduced into the slag discharge pipe 204. At this time, when the passive blade 303 swings under the action of turbulent water flow, it drives the sealing cover 307 to move back and forth along the axis of the mixing pipe 301 through the limiting block. During the movement, the sealing cover 307 intermittently opens the gap area between the two sealing sleeves 305, so that the screw rod 306 is exposed to the wastewater in this area in stages. During the process of the screw rod 306 rotating and conveying the agent, the intermittent opening structure allows the agent to fully contact the flowing wastewater and achieve dynamic mixing, thereby improving the mixing effect. As the amount of medicine inside the medicine bottle 103 gradually decreases, its overall weight decreases. Under the action of the return spring 115, the pressure ring 113 returns to its original position, thereby driving the movable gear 105 to re-engage with the drive gear 112, causing the slag discharge pipe 204 to resume rotation. At the same time, the solenoid valve inside the corresponding pressure pipe 102 opens. When the air pressure inside the air compressor 208 increases and pushes the pressure relief cover 209 to move axially, the vent hole 210 on the surface of the pressure relief cover 209 enters the air compressor 208. The cavity area allows gas to enter the interior of the compressor cylinder 208 through the vent 210. At the same time, the central rod 211 moves synchronously with the pressure relief cover 209, so that the air guide groove 213 on the surface of the central rod 211 forms a communication channel with the buffer tube 207 and the inner cavity of the compressor cylinder 208, so that the solid impurities in the tube are in a temporary suspended or loose state, thereby reducing their accumulation resistance. Then, under the continuous rotation of the guide spiral blade 205, the solid impurities inside the slag discharge pipe 204 can be smoothly transported and discharged. After the gas delivery process ends and the internal air pressure of the compressor 208 decreases, the center rod 211 resets in the opposite direction under the elastic force of the auxiliary spring 212, causing the pressure relief cover 209 to return to its initial position, disconnecting the air guide groove 213 from the buffer tube 207, and removing the vent 210 from the effective air guide area of ​​the compressor 208, thus completing an automatic opening and closing gas delivery and reset process. When the medicine bottle 103 is about to run out, due to the reduced weight, the reset spring 115 releases its elastic force to move the medicine bottle 103 upward, thus forming a conspicuous reminder. Then, the medicine bottle 103 can be replaced in time.

[0025] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
