Abstract

This invention relates to the field of concentration devices, specifically to a high-efficiency, non-powered concentration device, comprising: a device body and an artificial platform fixedly installed on the top of the device body; and a water inlet fixedly located in the middle of the artificial platform, the lower end of which penetrates the artificial platform and extends into the interior of the device body. This invention, by setting a flow-stabilizing section (preferably a fan-shaped honeycomb filter) arranged circumferentially along the inner wall of the device body, enables the core solid-liquid separation process of this device to be achieved entirely through gravity settling and structural rectification. On the one hand, this creates a relatively static and stable hydraulic environment for the settling of solid particles, significantly reducing the interference of turbulence and short-circuiting on the settling process, thereby greatly improving the solid-liquid separation efficiency, especially the ability to capture fine particles.

Description

Technical Field

[0001] This invention relates to the field of concentration devices, and more particularly to a high-efficiency, non-powered concentration device. Background Technology

[0002] During the screening, crushing, and transportation of ore, water spraying is often required to suppress dust dispersion. The resulting wastewater contains a large amount of suspended solid particles (such as mineral powder, soil, and gravel). Direct discharge or reuse without effective treatment not only wastes water resources but also leads to pipe blockages, equipment wear, and environmental pollution. Therefore, solid-liquid separation and concentration of this wastewater to achieve clean water reuse and sludge reduction is a crucial environmental protection aspect of mining production.

[0003] Currently, common solid-liquid separation equipment such as thickeners, sedimentation tanks, and hydrocyclones have certain limitations: traditional thickeners and large sedimentation tanks have large floor space requirements, low sedimentation efficiency, and high construction and operating costs; hydrocyclones and other power separation equipment require continuous power consumption or pumping power, resulting in high energy consumption, and their unstable internal flow field can easily affect the separation effect. Especially when the throughput fluctuates or the properties of solid particles change, the above-mentioned equipment cannot simultaneously guarantee efficient, stable, and low-energy operation. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a highly efficient, non-powered concentration device to solve the technical problems in the prior art.

[0005] To achieve the above objectives, the present invention provides a high-efficiency, non-powered concentration device, comprising: a device body and a manual platform fixedly installed on the top of the device body; A water inlet is fixedly installed in the middle of the artificial platform. The lower end of the water inlet penetrates the artificial platform and extends into the interior of the device body. The water inlet is used to receive ore wastewater from the ore screening and dust reduction treatment. Several flow stabilizing sections are equidistantly arranged along the circumferential direction of the inner wall of the upper end of the device body to decompose the large eddy current formed by ore wastewater into a stable laminar flow, thereby achieving stable solid-liquid separation. A drain outlet is fixed to one side of the bottom of the device body. The drain outlet is used to periodically discharge deposited heavy sludge such as sand and gravel.

[0006] Preferably, the device body is a cone-shaped body that is larger at the top and smaller at the bottom. An inspection port is provided on the other side of the bottom of the device body, and an inspection outlet is provided on the side of the device body opposite to the inspection port.

[0007] Preferably, the water inlet includes: a water inlet tank fixed in the middle of the artificial platform and a water inlet fixedly installed on the side wall of the water inlet tank for introducing ore wastewater; A connecting channel that communicates with the interior of the water inlet tank and is fixedly installed at its bottom; An adjusting screw threaded onto the top of the water inlet tank and a flow guide fixedly connected to the bottom of the adjusting screw; The lower end of the adjusting screw extends to the bottom of the connecting channel, and the guide is used to evenly disperse the mud entering the device body.

[0008] Preferably, a threaded sleeve is fixedly installed at the middle position of the top of the water inlet tank, and the outer surface of the upper end of the adjusting screw is threadedly connected to the inner ring of the threaded sleeve.

[0009] Preferably, a handwheel is fixedly connected to the top of the adjusting screw, and the outer surface of the handwheel is provided with anti-slip texture.

[0010] Preferably, the guide member is a conical structure with a smaller top and a larger bottom, and its conical surface is smoothly arranged.

[0011] Preferably, the device further includes a support frame fixed to the inner wall of the upper end of the device body for fixing and supporting the bottom of the flow stabilizing section, the support frame being a mesh structure; The flow stabilizing section is a honeycomb filter with a fan-shaped structure.

[0012] Preferably, a water collection tank is fixedly installed in a ring around the upper outer periphery of the device body. The water collection tank is arranged around the upper end of the device body and its height is higher than the top height of the device body, and is used to collect the clean water separated in the device body. A clean water outlet is fixed on one side of the bottom of the water collection tank for exporting and recycling the collected clean water.

[0013] Preferably, the device further includes a high-pressure air system for agitating and stirring the mud entering the device body. The high-pressure air system includes a high-pressure air source fixed to the outside of the device body, a plurality of air outlets located at the lower end of the device body, and at least one sealed connecting pipe connecting the high-pressure air source and the air outlets. The air outlet is sealed and connected to the high-pressure air source through a sealed connecting pipe, and the air outlet is located at one end inside the device body, below the guide component.

[0014] Preferably, the sealing connection pipe has an annular structure, and several air outlets are equidistantly arranged along the circumference of the sealing connection pipe.

[0015] The beneficial effects of this invention are as follows: The highly efficient, non-powered thickening device of this invention, by incorporating a flow-stabilizing section (preferably a fan-shaped honeycomb filter) arranged circumferentially along the inner wall of the device body, allows the core solid-liquid separation process to rely entirely on gravity settling and structural rectification. On the one hand, this creates a relatively static and stable hydraulic environment for the settling of solid particles, significantly reducing the interference of turbulence and short-circuiting on the settling process, thereby greatly improving the solid-liquid separation efficiency, especially the ability to capture fine particles. This results in low turbidity and clear water in the overflow supernatant, which can be directly reused in the production process, achieving efficient recycling of water resources. On the other hand, the overall energy consumption is extremely low, significantly reducing operating costs. Compared to hydrocyclones or large thickeners that require continuous electrical energy consumption, the "non-powered" design of this invention has outstanding energy-saving advantages in long-term operation, meeting the requirements of green and low-carbon environmental protection. The system utilizes a unique conical flow guide that works in conjunction with a bottom high-pressure air system. The flow guide ensures uniform dispersion of the incoming water, preventing impact on the bottom sludge bed. The high-pressure air system, on the one hand, enables rapid and uniform mixing when flocculants are added, promoting floc formation and enhancing the separation effect; on the other hand, it intermittently disturbs the bottom sludge, preventing it from caking and promoting further sludge concentration. Finally, high-concentration sludge can be discharged through the bottom drain, achieving sludge volume reduction and alleviating the load on subsequent sludge treatment.

[0016] By adopting a conical structure design that is larger at the top and smaller at the bottom, the large cross-section at the top reduces the upward velocity of the water flow, which is conducive to sedimentation, while the lower cone facilitates the concentration and collection of sludge. This allows the equipment to achieve efficient treatment in a limited space with a small footprint. Attached Figure Description

[0020] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0021] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0022] The first aspect of this invention provides a highly efficient, non-powered concentration device, such as... Figure 1-5 As shown, it includes: device body 1 and artificial platform 2 fixedly installed on the top of device body 1; The water inlet 3 is fixedly installed in the middle of the artificial platform 2. The lower end of the water inlet 3 penetrates the artificial platform 2 and extends into the interior of the device body 1. The water inlet 3 is used to access the ore wastewater from the ore screening and dust reduction treatment. Several flow stabilizing sections 4 are equidistantly arranged along the circumferential direction of the upper inner wall of the device body 1 to decompose the large eddy current formed by the ore wastewater into a stable laminar flow, thereby achieving stable solid-liquid separation. It should be noted that the flow stabilizing section 4 is preferably made of materials such as polyethylene (PE) or polypropylene (PP), and its pore size can be selected according to the characteristics of the wastewater being treated. The honeycomb pores can be regular hexagonal, with a pore spacing of 20-60 mm. The pore size selection corresponds to the particle size of the solid particles in the ore wastewater: when treating fine particle wastewater with a solid particle size of 0.01-0.1 mm, a pore size of 10-20 mm is selected; when treating coarse particle wastewater with a solid particle size of 0.1-5 mm, a pore size of 30-50 mm is selected; and when treating mixed particle wastewater, a pore size of 20-30 mm is selected. The honeycomb pores are arranged perpendicular to the upward direction of the water flow, ensuring that the water flow can be fully cut and rectified as it passes through, decomposing large eddies into stable laminar flow. Its core function is to cut and comb the upward water flow and the bubble-floc combination, decomposing large eddies into stable laminar flow or small-scale flow, creating a quiet environment for solid-liquid separation, and improving flotation efficiency and effluent quality.

[0023] A drain port 5 is fixed to one side of the bottom of the device body 1. The drain port 5 is used to periodically discharge the deposited heavy sludge such as sand and gravel. The drain port 5 can be connected to a slurry pump through a flange, and the pump can be turned on periodically or continuously to discharge the concentrated heavy sludge.

[0024] In this embodiment: the device body 1 is a cone-shaped body, wider at the top and narrower at the bottom, and is made of carbon steel or stainless steel. This cone-shaped structure facilitates the collection and concentration of settled solid particles towards the central area at the bottom, forming a high-concentration sludge bed. Simultaneously, the larger cross-sectional area at the top reduces the upward velocity of the water flow, promoting the settling of fine particles. This allows the equipment to achieve efficient processing within a limited space, occupying a small area. An inspection port 6 is provided on the other side of the bottom of the device body 1, and a maintenance outlet 7 is provided on the side of the device body 1 opposite to the inspection port 6. The inspection port 6 is used for equipment maintenance and cleaning; the maintenance outlet 7, located on the side opposite to the inspection port 6, allows for the drainage of liquid from the device during maintenance.

[0025] In this embodiment: the water inlet 3 includes: a water inlet tank fixed in the middle of the artificial platform 2 and a water inlet 301 fixedly installed on the side wall of the water inlet tank for introducing ore wastewater; A connecting channel 302 that communicates with the interior of the water inlet tank and is fixedly installed at its bottom; An adjusting screw 303 is threaded onto the top of the water inlet tank, and a flow guide 304 is fixedly connected to the bottom of the adjusting screw 303; The lower end of the adjusting screw 303 extends to the bottom of the connecting channel 302, and the guide 304 is used to evenly disperse the mud entering the device body 1.

[0026] By rotating the adjusting screw 303, the height position of the guide component 304 inside the connecting channel 302 and the device body 1 can be precisely controlled (generally, counterclockwise rotation is for lifting, and clockwise rotation is for lowering). The guide component 304 is used to evenly disperse the mud entering the device body 1, preventing the water flow from directly impacting the bottom mud bed or forming concentrated eddies; Wastewater generated from dust settling during ore screening enters through inlet 301 and is evenly dispersed by adjustable-height guide vanes 304, reducing the water flow velocity. Subsequently, the water flow is rectified by flow stabilizer 4 during its ascent, resulting in a stable flow pattern. Solid particles settle to the bottom and concentrate under gravity. The supernatant overflows from the top of the unit body 1 and is collected for reuse. The concentrated sludge at the bottom is periodically pumped out from outlet 5 by a slurry pump.

[0027] In this embodiment, a threaded sleeve 3031 is fixedly installed at the middle position of the top of the water inlet tank, and the outer surface of the upper end of the adjusting screw 303 is threadedly connected to the inner ring of the threaded sleeve 3031. This enables the adjustment of the flow guide 304 at the bottom of the adjusting screw 303.

[0028] In this embodiment, a handwheel 3032 is fixedly connected to the top of the adjusting screw 303, and the outer surface of the handwheel 3032 is provided with anti-slip texture. This facilitates the operator to rotate the adjusting screw 303.

[0029] In this embodiment, the guide member 304 is a conical structure with a smaller top and a larger bottom, and its conical surface is smoothly designed. It can guide the mud to spread evenly in all directions and avoid the generation of local eddies.

[0030] In this embodiment, the device also includes a support frame 8 fixed to the inner wall of the upper end of the device body 1 for fixing and supporting the bottom of the flow stabilizing part 4. The support frame 8 has a mesh structure to ensure that the water flow is not interfered with.

[0031] The flow stabilizing section 4 is a honeycomb filter with a fan-shaped structure. The flow stabilizing section 4 can be formed by assembling 8 identical fan-shaped filter screens along the circumferential direction of the upper inner wall of the device body 1. The assembly gap between adjacent fan-shaped filter screens is ≤2mm to avoid the generation of local eddies. The support frame 8 is a stainless steel mesh grille, which is fixedly connected to the upper inner wall of the device body 1 by welding, providing support while allowing water to flow freely. As the diffused water flow from the guide component 304 rises, it is cut and rectified by the honeycomb-shaped flow stabilizer 4, where the remaining large-scale eddies are broken down and the water flow tends to be in a gentle laminar flow state. This allows solid particles (especially finer particles) in the sewage to settle effectively by gravity in a relatively static environment. On the one hand, it creates a relatively static and stable hydraulic environment for the sedimentation of solid particles, significantly reducing the interference of turbulence and short-circuiting on the sedimentation process, thereby greatly improving the solid-liquid separation efficiency, especially the ability to capture fine particles. This results in low turbidity and clear water in the overflow supernatant, which can be directly reused in the production process, achieving efficient recycling of water resources. On the other hand, the overall energy consumption is extremely low, and the operating cost is significantly reduced. Compared with hydrocyclones or large thickeners that require continuous power consumption, the "powerless" design of this invention has outstanding energy-saving advantages in long-term operation and meets the requirements of green and low-carbon environmental protection.

[0032] In this embodiment: A water collection tank 9 is fixedly installed in a ring around the upper outer periphery of the device body 1. The water collection tank 9 is arranged around the upper end of the device body 1 and its height is higher than the top height of the device body 1. It is used to collect the separated clean water inside the device body 1. A clean water outlet 10 is fixed to one side of the bottom of the water collection tank 9 for discharging and recycling the collected clean water. The clarified water continues to rise and eventually overflows from the top edge of the device body 1, entering the annular water collection tank 9. The bottom of the water collection tank 9 is equipped with a clean water outlet 10 to draw out the collected clean water for reuse.

[0033] In this embodiment: the device also includes a high-pressure air system for agitating and stirring the mud entering the device body 1. The high-pressure air system includes a high-pressure air source fixed to the outside of the device body 1, a plurality of air outlets 1101 located at the lower end of the device body 1, and at least one sealed connecting pipe 11 connecting the high-pressure air source and the air outlets 1101. The air outlet 1101 is sealed and connected to the high-pressure air source through the sealed connecting pipe 11, and the air outlet 1101 is located at one end inside the device body 1, below the guide member 304.

[0034] In this embodiment: the sealing connection pipe 11 has a ring structure, and several air outlets 1101 are equidistantly arranged along the circumference of the sealing connection pipe 11. The sealing connection pipe 11 is made of stainless steel and is sealed and fixed to the side wall of the device body 1 by a flange connection (a rubber sealing gasket is set at the flange connection, and the sealing pressure is ≥0.6MPa to prevent sewage leakage). Several air outlets 1101 are equidistantly arranged along the circumference of the sealing connection pipe 11 (the number is 4-8, corresponding to the diameter of the device body 1). The air outlet diameter of the air outlet 1101 is 10-20mm, and it faces upward at a 45° angle to ensure that the high-pressure air is blown evenly into the interior of the device body 1 and does not directly impact the bottom mud bed.

[0035] The high-pressure air system serves two main purposes. First, it is activated when flocculants are added. When flocculants are needed to treat fine particles or colloidal substances, they can be added before the inlet 301 or into the inlet tank. After the wastewater containing flocculants is initially dispersed by the guide vane 304, it is immediately subjected to strong agitation by the uniformly rising high-pressure air from the bottom of the device body 1. This area facilitates rapid and uniform mixing and reaction, forming dense flocs. This further promotes uniform mixing of the wastewater and flocculant, and allows light suspended solids and grease in the wastewater to float to the surface with the microbubbles, while heavy impurities such as sand and gravel naturally settle, thus greatly accelerating the subsequent settling process. Second, during non-chemical operation, the high-pressure air system can be intermittently activated for short periods to gently agitate the sludge deposited at the bottom, preventing caking and promoting further sludge concentration.
