Description

Technical Field

[0001] The embodiments of the present invention relate to the field of flotation desliming technology, specifically to a flotation feed desliming device coupled with ultrasonic dispersion and an adjustable inclined plate. Background Technology

[0002] In existing technologies, after mining ore, the ore undergoes crushing and grinding operations. However, the ore particles at the feed inlet of existing flotation equipment contain a lot of mud and impurities. When these mud and impurities mix with the ore particles, a layer of mud film forms on the surface of the ore particles, affecting the subsequent flotation operation. Therefore, before the ore particles are subjected to flotation, it is necessary to deslim the ore particles to remove the mud mixed in with them.

[0003] In existing technologies, desliming devices are typically installed at the feed end of flotation equipment to pre-classify and deslim the slurry before flotation operations. Since ore particles easily generate a large amount of fine mud during crushing and grinding, this fine mud tends to adhere to the surface of the ore particles, forming a mud film that affects subsequent flotation separation. Therefore, physical methods are usually required to enhance the liberation between ore particles and fine mud during the desliming process.

[0004] In existing technologies, physical methods such as ultrasonic dispersion can be used to treat the slurry entering the desliming device to break down the mud film on the surface of the ore particles, allowing fine mud to detach from the ore particle surface. After ultrasonic dispersion, the slurry flows within the desliming device, forming a relatively stable laminar flow state through the inclined plate structure. Under hydraulic classification, larger ore particles settle and slide down the inclined plates, while smaller fine mud particles are carried by the rising water flow into the overflow, thus achieving graded desliming of the slurry.

[0005] However, during the desliming process, fine mud tends to accumulate at the bottom of the desliming device and on the surface of the inclined plate. After long-term operation, this can lead to the accumulation of fine mud inside the device and blockage of the flow channel, affecting the desliming effect. Furthermore, it is difficult to clean the fine mud inside the device, which reduces the stability and reliability of the equipment operation. Summary of the Invention

[0006] To overcome the problem that fine mud accumulation and cleaning difficulties easily occur in existing desliming devices used to remove fine mud from flotation feed slurry during long-term operation, this invention provides a flotation feed desliming device that couples ultrasonic dispersion with an adjustable inclined plate.

[0007] The present invention provides a flotation feed desliming device coupled with ultrasonic dispersion and adjustable inclined plates, including a desliming chamber and multiple desliming inclined plates. The desliming device is set at the feed end of the flotation equipment and is used to classify and deslim the slurry before flotation operation.

[0008] The coupling ultrasonic dispersion unit is provided between the support platform fixedly connected to the top of the desliming chamber and the inner top wall of the desliming chamber, so as to separate the ore particles and mud in the slurry. During the desliming process, the slurry to be treated first enters the coupled ultrasonic dispersion unit in the desliming machine box. The ultrasonic dispersion action breaks down the mud film formed on the surface of the ore particles, allowing the fine mud attached to the surface of the ore particles to be fully dissociated. A fluid transition component is provided inside the desliming chamber, and a support frame is provided inside the chamber. The fluid transition component is located between the support platform and the support frame. The slurry discharged from the coupled ultrasonic dispersion unit flows through the fluid transition component and then enters the range of the multiple desliming inclined plates. After ultrasonic dispersion, the slurry then enters the fluid transition component. Under the guidance of the fluid transition component, the slurry flow state changes from turbulent to relatively stable laminar flow. Under laminar flow conditions, the slurry flows along multiple desliming inclined plates inside the desliming chamber. Utilizing the principle of hydraulic classification, larger ore particles settle and slide down the desliming inclined plates to form the underflow, while smaller fine mud particles enter the overflow with the rising water flow. This achieves the classification and desliming treatment of the flotation feed slurry. The underflow slurry formed after desliming treatment has a reduced fine mud content and a stable particle size distribution, making it suitable as the feed slurry for subsequent flotation operations. Meanwhile, the fine mud enriched in the overflow is effectively separated and discharged.

[0009] An adjustable inclined plate installation structure is provided at the bottom of the desliming machine box. This structure is used to place multiple desliming inclined plates at the bottom of the desliming machine box and adjust the inclination angle of the desliming inclined plates. By setting the adjustable inclined plate installation structure, the desliming conditions can be adjusted according to the properties of the slurry. The bottom of the adjustable inclined plate installation structure is provided with multiple overlapping closed support plates for adjusting the opening and closing of the bottom of the desliming machine box; The flushing and sludge discharge structure is provided at the bottom of the support frame to flush and discharge the fine sludge on the desludge inclined plate and the closed support plate.

[0010] Meanwhile, the flushing and sludge removal structure can flush and remove fine sludge from the desliming inclined plate and the bottom of the device during operation or shutdown, reducing the accumulation of fine sludge inside the device and improving the stability and reliability of the desliming device.

The adjustable inclined plate mounting structure includes a fixed frame, a mounting trough, a movable chute, and a connecting push rod. The fixed frame is fixedly connected inside the desliming chamber. Multiple mounting troughs are fixedly connected inside the fixed frame, and the number of mounting troughs corresponds one-to-one with the number of desliming inclined plates. The bottom of the desliming inclined plate is rotatably connected to the mounting trough via a rotating shaft. The movable chute is provided on both sides of the top of the mounting trough. An adjusting slider is slidably connected inside the movable chute. A connecting push rod is rotatably connected between the adjusting slider and the side wall of the desliming inclined plate.

A connecting rod is fixedly connected between a plurality of adjusting sliders located on the same side. A connecting frame is slidably connected through one side of the desliming chamber. The connecting frame is fixedly connected to the connecting rod. A first electric cylinder is provided on the outer wall of the desliming chamber to drive the connecting frame to move.

[0015] At least one embodiment of the present invention provides a flotation feed desliming device that couples ultrasonic dispersion with an adjustable inclined plate. The closed support plate is rotatably connected to the fixed frame through connecting shafts located on both sides. A cavity is provided between the fixed frame and the side wall of the desliming chamber. The connecting shaft is rotatably connected through the cavity.

[0016] At least one embodiment of the present invention provides a flotation feed desliming device that couples ultrasonic dispersion with an adjustable inclined plate. A transmission gear is fixedly sleeved on a connecting shaft located in the cavity. A transmission rack is connected to multiple transmission gears for transmission. A connecting member is slidably connected through the side wall of the desliming chamber. The connecting member is fixedly connected to the transmission rack. A second electric cylinder is provided on the outer wall of the desliming chamber to drive the connecting member to move laterally.

[0017] At least one embodiment of the present invention provides a flotation feed desliming device coupled with ultrasonic dispersion and an adjustable inclined plate. The flushing and desliming structure includes a flushing cylinder and a water supply pipeline. The flushing cylinder is slidably disposed at the bottom of the support frame. Multiple flushing nozzles are connected to the bottom of the flushing cylinder.

[0020] The beneficial effects of the embodiments of the present invention are as follows: 1. This invention sets up a coupled ultrasonic dispersion unit in the desliming device to perform ultrasonic dispersion treatment on the slurry entering the desliming chamber without introducing flotation reagents. This effectively destroys the mud film formed on the surface of ore particles, promotes the dissociation of fine mud attached to the surface of ore particles, and improves the desliming efficiency of the slurry.

[0021] 2. This invention, by setting up honeycomb-shaped guide plates inside the desliming chamber, transforms the ultrasonically dispersed slurry from a turbulent state to a relatively stable laminar flow state. Combined with multiple desliming inclined plates driven by the adjustable inclined plate installation structure, the hydraulic classification principle is used to cause larger ore particles to settle and slide down the desliming inclined plates to form the underflow, while smaller fine mud particles enter the overflow with the rising water flow. This achieves effective classification and desliming of the flotation feed slurry, reducing the interference of fine mud on subsequent flotation operations.

[0022] 3. By setting an adjustable tilting desliming inclined plate and an openable and closable closed support plate, the desliming conditions can be adjusted according to the properties of the slurry. In conjunction with the flushing and sludge discharge structure, the fine mud on the surface of the desliming inclined plate and the closed support plate is flushed and discharged, which effectively prevents the accumulation of fine mud inside the device, facilitates equipment maintenance, and improves the stability and reliability of the device operation.

[0031] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0032] like Figures 1 to 7 As shown, the present invention discloses a flotation feed desliming device coupled with ultrasonic dispersion and adjustable inclined plates, including a desliming chamber 1 and multiple desliming inclined plates 2, which are set at the feed end of the flotation equipment. Because when mud and ore particles are mixed and encounter flotation liquid, the mud will form a mud film that wraps around the ore particles, affecting the flotation operation of the ore particles, the desliming chamber 1 is set at the feed end used for flotation processing of ore particles.

[0033] It also includes a coupled ultrasonic dispersion unit. A support platform 3 is fixedly connected to the top of the desliming chamber 1. A coupled ultrasonic dispersion unit is set between the support platform 3 and the inner top wall of the desliming chamber 1 to separate the ore particles and mud in the slurry. The coupled ultrasonic dispersion unit includes a mounting box 6, which is fixedly connected between the support platform 3 and the inner top wall of the desliming chamber 1. An array of ultrasonic transducers 7 is set inside the mounting box 6. After the slurry enters the desliming chamber 1, the slurry first enters the mounting box 6, and then multiple ultrasonic transducers 7 are used to perform coupled ultrasonic dispersion on the slurry flowing in the mounting box 6 to disperse the fine mud attached to the surface of the ore particles. The desliming chamber 1 is equipped with a support frame 4. A fluid transition component is set between the support platform 3 and the support frame 4. The slurry discharged from the coupled ultrasonic dispersion unit flows through the fluid transition component and then enters the range of multiple desliming inclined plates 2. The fluid transition component includes multiple honeycomb guide plates 8, which are set between the support platform 3 and the support frame 4. The honeycomb guide plates 8 change the turbulent flow of the slurry after coupled ultrasonic dispersion to laminar flow. After ultrasonic dispersion, the slurry enters between the multiple honeycomb guide plates 8 of the support platform 3 and the support frame 4, and then changes the originally turbulent slurry to a laminar flow state, providing conditions for subsequent separation of different particle sizes using the principle of hydraulic classification.

[0034] The bottom of the desliming machine housing 1 is equipped with an adjustable inclined plate mounting structure for mounting multiple desliming inclined plates 2 at the bottom of the desliming machine housing 1 and adjusting the tilt angle of the desliming inclined plates 2. The adjustable inclined plate mounting structure includes a fixed frame 9, a mounting bracket 10, a movable slide 11, and a connecting push rod 12. The fixed frame 9 is fixedly connected inside the desliming machine housing 1. Multiple mounting brackets 10 are fixedly connected inside the fixed frame 9, and the number of mounting brackets 10 corresponds one-to-one with the number of desliming inclined plates 2. The bottom of the desliming inclined plates 2 is rotatably connected to the fixed frame 1 via a rotating shaft. Inside the mounting frame 10, movable slids 11 are provided on both sides of the top of the mounting frame 10. Adjustable sliders are slidably connected in the movable slids 11. A connecting push rod 12 is rotatably connected between the adjusting slider and the side wall of the desliming inclined plate 2. When it is necessary to adjust the tilt angle of multiple desliming inclined plates 2 to adapt to the distribution height of mud in the slurry, the adjusting slider is pushed to slide in the movable slids 11, changing the tilt angle of the connecting push rod 12, so that the desliming inclined plate 2 rotates along the center point of the rotation axis, and the tilt angle of the desliming inclined plate 2 in the mounting frame 10 is adjusted.

[0035] A connecting rod 13 is fixedly connected between multiple adjusting sliders located on the same side. A connecting frame 14 is slidably connected through one side of the desliming machine box 1. The connecting frame 14 is fixedly connected to the connecting rod 13. A first electric cylinder 15 is provided on the outer wall of the desliming machine box 1 to drive the connecting frame 14 to move. When the first electric cylinder 15 is started, the connecting frame 14 and the two connecting rods 13 are pushed to move laterally, thereby synchronously adjusting the position of multiple adjusting sliders and realizing synchronous adjustment of the tilt angle of multiple desliming inclined plates 2.

[0036] The adjustable inclined plate installation structure has multiple overlapping closed support plates 5 at its bottom, which are used to adjust the opening and closing of the bottom of the desliming machine box 1. The closed support plates 5 are rotatably connected to the fixed frame 9 through the connecting shafts 16 located on both sides. A cavity is provided between the fixed frame 9 and the side wall of the desliming machine box 1. The connecting shafts 16 are rotatably connected through the cavity. The overlapping closed support plates 5 prevent the slurry from leaking to the lower side of the closed support plates 5. After the soil accumulates on the surface of the closed support plates 5, it will further increase the sealing of the multiple closed support plates 5. After the slurry is fully deslimed, the slurry for subsequent flotation process is discharged into the double cone discharge hopper 28 through the closed support plates 5.

[0037] A transmission gear 17 is fixedly sleeved on the connecting shaft 16 located in the cavity. A transmission rack 18 is connected between multiple transmission gears 17 for transmission. A connecting piece 19 is slidably connected through the side wall of the desliming machine box 1. The connecting piece 19 is fixedly connected to the transmission rack 18. A second electric cylinder 20 is provided on the outer wall of the desliming machine box 1 to drive the connecting piece 19 to move laterally. After the desliming process of the slurry is completed, when it is necessary to discharge the fine mud retained on the closed support plate 5, the second electric cylinder 20 is activated to push the connecting piece 19 and the two transmission racks 18 to move laterally, thereby driving the transmission gear 17 to rotate and causing the multiple closed support plates 5 to rotate to a vertical state, so as to facilitate the discharge of fine mud on the closed support plate 5 and the desliming inclined plate 2.

[0038] The bottom of the support frame 4 is equipped with a flushing and sludge discharge structure for flushing and discharging fine sludge from the desludge dewatering inclined plate 2 and the closed support plate 5. The flushing and sludge discharge structure includes a flushing cylinder 21 and a water supply pipe 23. The flushing cylinder 21 is slidably disposed at the bottom of the support frame 4, and multiple flushing nozzles 22 are connected to the bottom of the flushing cylinder 21. The water supply pipe 23 is slidably disposed through the desludge dewatering machine box 1 and is connected to the flushing cylinder 21. When it is necessary to completely discharge the desorbed fine sludge, cleaning water is supplied through the water supply pipe 23. 3. The water is conveyed into the washing cylinder 21. Finally, multiple washing nozzles 22 are used to spray the washing water to wash the fine mud on the surface of the desliming inclined plate 2 and the closed support plate 5. Because the fine mud has weak adhesion, when the tilt angle of the desliming inclined plate 2 and the closed support plate 5 is initially adjusted, some of the fine mud can directly enter the double cone discharge hopper 28. In the subsequent washing process, as much fine mud as possible is allowed to enter the double cone discharge hopper 28, and the fine mud that is washed off is also discharged through the double cone discharge hopper 28.

[0039] The support frame 4 is equipped with a screw drive structure 29 that drives the rinsing cylinder 21 to move laterally. The bottom of the support frame 4 is fixedly connected to a suspension trough 30, and a transmission seat 31 is slidably connected inside the suspension trough 30. The rinsing cylinder 21 is fixedly connected to the bottom of the transmission seat 31. The screw drive structure 29 and the transmission seat 31 are in transmission cooperation. The outside of the desludge dewatering machine box 1 is equipped with a drive motor 32 that drives the screw drive structure 29. In order to ensure that the rinsing cylinder 21 performs even rinsing operations on all the components at the top of the fixed frame 9, the drive motor 32 drives the screw drive structure 29, which in turn drives the transmission seat 31 and the rinsing cylinder 21 to move laterally within the range of the suspension trough 30.

[0040] The desliming chamber 1 is equipped with a feed pipe 24 and a drain pipe 25 on both sides. The feed pipe 24 corresponds to the mounting chamber 6, and the drain pipe 25 corresponds to the desliming inclined plate 2. A turbidity sensor 26 is installed on the drain pipe 25. A particle size sensor 27 is installed on the side wall of the desliming chamber 1. The ore slurry mixed with mud can be added to the mounting chamber 6 inside the desliming chamber 1 through the feed pipe 24. The clear liquid after desliming by the desliming inclined plate 2 can be discharged through the drain pipe 25. The turbidity sensor 26 can be used to judge the desliming effect of the slurry, which is convenient for subsequent flotation of ore particles. After the slurry passes through the honeycomb guide plate 8, the particle size sensor 27 monitors the particle size distribution in the slurry to help judge the desliming effect and adjust the tilt angle of the desliming inclined plate.

[0041] The bottom of the desliming machine box 1 is connected to a double-cone discharge hopper 28 for discharging slurry. When the slurry is deslimed, the deslimed slurry can be discharged through the double-cone discharge hopper 28. When the fine mud retained on the desliming inclined plate 2 and the closed support plate 5 is discharged in the subsequent process, the fine mud that has been washed off can also be discharged into the double-cone discharge hopper 28 and then discharged by the double-cone discharge hopper 28.

[0042] The working principle of this desliming device that couples ultrasonic dispersion with an adjustable inclined plate for flotation feed is as follows: This flotation feed desliming device, which couples ultrasonic dispersion with an adjustable inclined plate, is used as a pretreatment device before flotation operations to classify and deslim the flotation feed slurry.

[0043] During operation, the slurry to be processed is transported to the desliming chamber 1 through the feed pipe 24 and first enters the coupled ultrasonic dispersion unit set at the top of the desliming chamber 1. As the slurry flows through the installation chamber 6, it undergoes ultrasonic dispersion treatment under the action of the ultrasonic transducer 7. The mud film formed on the surface of the ore particles is destroyed by ultrasonic cavitation and vibration, so that the fine mud attached to the surface of the ore particles is fully dissociated.

[0044] After ultrasonic dispersion, the slurry flows out of the mounting box 6 and enters the fluid transition component set between the support platform 3 and the support frame 4. Under the guidance of the honeycomb guide plate 8, the slurry gradually changes from the original turbulent state to a relatively stable laminar state, providing favorable fluid conditions for the subsequent staged desliming process.

[0045] In laminar flow, the slurry flows along multiple desliming inclined plates 2 located at the bottom of the desliming chamber 1, utilizing the principle of hydraulic classification to separate particles of different sizes in the slurry. Larger ore particles with faster settling velocities settle under gravity and slide down the surface of the desliming inclined plates 2 to form the underflow; smaller fine mud particles with slower settling velocities enter the overflow with the rising water flow, thus achieving the classification and desliming treatment of the flotation feed slurry.

[0046] The underflow slurry formed after the graded desliming process is discharged from the lower part of the desliming chamber 1 through the double-cone discharge hopper 28, serving as the feed slurry for subsequent flotation operations. The fine mud enriched in the overflow is discharged from the upper part of the desliming chamber 1, achieving effective removal of fine mud. The turbidity sensor 26 installed on the discharge pipe 25 and the particle size sensor 27 installed on the side wall of the desliming chamber 1 can monitor the slurry state during the desliming process to assist in adjusting the tilt angle of the desliming inclined plate 2 and the operating conditions of the device.

[0047] During operation, some fine sludge may deposit on the surfaces of the desliming inclined plate 2 and the closed support plate 5, as well as at the bottom of the desliming chamber 1. In this case, the angle of inclination of the desliming inclined plate 2 and the closed support plate 5 can be adjusted to allow the deposited fine sludge to collect downwards. Combined with the flushing and sludge discharge structure located at the bottom of the support frame 4, washing water is sprayed onto the surfaces of the desliming inclined plate 2 and the closed support plate 5, allowing the fine sludge to enter the bottom of the desliming chamber 1 and be discharged through the double-cone discharge hopper 28. This prevents the fine sludge from accumulating inside the device for a long period, ensuring the continuous and stable operation of the desliming unit.

[0048] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
