Description

Technical Field

[0001] The invention relates to the technical field of ore dressing equipment, in particular to an ore dressing thickener with a defoaming structure. Background Art

[0002] The mineral processing thickener is a widely used equipment in the mineral processing process. It is mainly used for the concentration and sedimentation of ore pulp to improve the recovery rate and concentration of ore. In the mineral processing process, the ore pulp is often accompanied by the generation of a large number of bubbles. These bubbles form a foam layer in the thickener, which affects the sedimentation process of the ore pulp and reduces the separation efficiency and recovery rate of the ore. Traditional defoaming technology mainly relies on chemical defoamers, mechanical defoaming or water flow impact to remove foam, but these methods have many shortcomings. First, the use of chemical defoamers may cause environmental pollution, changes in the water quality of the ore pulp, and may even affect the recovery effect of the mineral. Secondly, although mechanical defoaming can effectively remove surface foam, it usually requires a large amount of mechanical energy consumption, and the defoaming efficiency is low when the bubbles are unevenly distributed. Thirdly, although the water flow impact method can remove foam through high-pressure water flow, excessive reliance on water flow not only increases water consumption, but also leads to an increase in wastewater discharge, resulting in waste of water resources and environmental burden. In addition, traditional defoaming methods also have a large impact on the equipment, accelerate equipment wear, and reduce the service life of the equipment.

DETAILED DESCRIPTION

[0020] The following will be combined with the drawings in the specification of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] Please refer to the attached Figure 1 - Attachment Fig.10The embodiment of the present invention provides a mineral processing thickener with a defoaming structure, including a thickener body 1, a mounting frame 2 is fixedly connected to the top of the thickener body 1, a mounting shell 3 is installed on the inner side of the mounting frame 2, a dual-axis motor 501 is installed on the inner side of the mounting shell 3, a connecting shaft 502 is installed on the inner side of the mounting shell 3, one end of the connecting shaft 502 and the output end of the dual-axis motor 501 are fixedly connected with a first bevel gear 508, a connecting piece 507 is rotatably installed on the inner bottom wall of the mounting shell 3, a second bevel gear 509 is installed on the top of the connecting piece 507, the outer side of the second bevel gear 509 is meshed with the outer sides of the two first bevel gears 508, the other end of the connecting shaft 502 is fixedly connected to a driving turntable 503, and a driving block 504 is fixedly connected to the outer eccentricity of the driving turntable 503, and the mounting The inner side of the shell 3 is fixedly connected to a limiting frame 506, the inner side of the limiting frame 506 is slidably connected to a connecting frame 505, the outer side of the mounting shell 3 is fixedly connected to a fixing cylinder 602, the inner side of the fixing cylinder 602 is slidably connected to a rubber piston 605, the outer side of the rubber piston 605 is fixedly connected to a movable rod 601, the outer side of the fixing cylinder 602 is sequentially connected to a connecting pipe 603 and an air intake pipe 604, and the dual-axis motor 501 drives the driving block 504 outside the driving turntable 503 to rotate eccentrically, and then drives the movable rod 601 to reciprocate left and right, further driving the rubber piston 605 to move left and right, and when the rubber piston 605 moves to the right, the air inside the fixing cylinder 602 is ejected through the connecting pipe 603. One end of the connecting tube 603 is connected to the outer side of the connecting piece 507 , and the top end of the fixed tube 803 is fixedly connected to the jet pipe 606 , and a plurality of jet holes are arranged on the outer side of the jet pipe 606 .

[0022] Specifically, the accommodating structure inside the mounting frame 2 has built-in components such as a dual-axis motor 501 and a connecting shaft 502. Its function is to provide a working environment for the motor and the drive system. The driving turntable 503 is driven to rotate by the connecting shaft 502, and the driving block 504 is fixed at the eccentric position of the driving turntable 503, driving other components to perform eccentric motion. The driving block 504 cooperates with the groove inside the connecting frame 505 to ensure the accuracy and consistency of the motion. The connecting frame 505 is slidably connected to the limiting frame 506 in the mounting shell 3. The eccentric motion of the driving block 504 will drive the connecting frame 505 to perform horizontal reciprocating motion, thereby pulling the movable rod 601. One end of the movable rod 601 is fixedly connected to the rubber piston 605. When the movable rod 601 reciprocates left and right, the rubber piston 605 will move left and right in the fixed cylinder 602. The fixed cylinder 602, as the main part of the airflow regulation, realizes the removal of bubbles through the internal airflow control system. When the rubber piston 605 moves in the reverse direction, the gas in the fixed cylinder 602 will be discharged through the air injection pipe 606 .

[0023] A plurality of gas injection holes are provided on the gas injection pipe 606, and these gas injection holes are used to release the exhausted gas in the form of high-speed injection, so as to directly eliminate the bubbles in the ore pulp.

[0024] The dual-axis motor 501 is started, and the power at its output end is transmitted to the connecting shaft 502 through the first bevel gear 508, and the connecting shaft 502 further drives the second bevel gear 509 to rotate, thereby driving the entire transmission system. Through the transmission effect, the drive turntable 503 rotates synchronously, and the eccentric drive block 504 drives the connecting frame 505 to reciprocate left and right. The connecting frame 505 drives the movable rod 601 to move left and right, and the movable rod 601 pulls the rubber piston 605 to slide along the inner wall of the fixed cylinder 602. When the rubber piston 605 moves to the right, the air in the fixed cylinder 602 enters the cylinder through the air inlet pipe 604 and provides airflow for the next operation. When the rubber piston 605 moves in the opposite direction, the air in the fixed cylinder 602 is discharged through the connecting pipe 603, and finally ejected at high speed through the air jet hole outside the air jet pipe 606, forming a strong airflow. This airflow will effectively eliminate bubbles in the slurry. This airflow can defoam through the jet action, which can effectively reduce the negative impact of bubbles on the pulp concentration effect, thereby improving the working efficiency of the mineral processing thickener and the pulp treatment effect.

[0025] A groove is provided inside the connecting frame 505, and the driving block 504 is arranged inside the groove. One end of the movable rod 601 is fixedly connected to the outer side of the connecting frame 505. One-way valves are installed on the inner sides of the connecting pipe 603 and the air intake pipe 604, and the conduction directions of the two one-way valves are opposite.

[0026] Specifically, one-way valves are installed in the connecting pipe 603 and the air inlet pipe 604. The one-way valve is a device that allows fluid to flow in only one direction. The two one-way valves have opposite conduction directions, which means that they control the fluids flowing in different directions respectively.

[0027] The top of the mounting frame 2 is fixedly connected with a fixed shell 701, the outer side of the fixed shell 701 is installed with a driving motor 702, the output end of the driving motor 702 is fixedly connected with a driving screw 704, the outer side of the driving screw 704 is threadedly connected with a threaded plate 705, the outer side of the threaded plate 705 is fixedly connected with a movable plate 706, the outer side of the fixed shell 701 is sequentially connected with a first connecting pipe 707 and a second connecting pipe 708, and the bottom end of the second connecting pipe 708 is fixedly connected with an annular pipe 703. The longitudinal section of the movable plate 706 is set to be square, and the outer surface of the movable plate 706 is slidably connected with the inner wall of the fixed shell 701. The outside of the first connecting pipe 707 and the second connecting pipe 708 are both installed with mounting valves, and the annular pipe 703 is fixedly connected to the inner side of the thickener body 1. In addition, the fixed shell 701 is designed with a transparent material, and its outer surface is provided with a scale.

[0028] Specifically, the mounting frame 2 plays a supporting and fixing role. The mounting frame 2 is fixedly connected to the fixed shell 701 through the top, ensuring that the position of the fixed shell 701 is stable and can withstand the working pressure inside it.

[0029] The fixed shell 701 is the outer shell of the entire device, and there is a cavity inside it, which serves as a container for the flocculant. The shell not only provides mechanical support and protection, but also has a transparent design, which is convenient for observing the state and operation of the liquid inside. At the same time, there are scales on the outer wall to help operators accurately monitor and adjust the usage or flow of the liquid inside the device.

[0030] Threaded plate 705: The threaded plate 705 is threadedly connected to the driving screw 704, and can move precisely left and right along the axial direction of the screw under the rotation of the screw. The movement of the threaded plate 705 is proportional to the rotation angle of the driving screw 704, thereby controlling the displacement of the threaded plate 705 and further determining the discharge amount of the flocculant.

[0031] The outer side of the threaded plate 705 is fixedly connected to the movable plate 706, and the movable plate 706 moves synchronously with the movement of the threaded plate 705, thereby pushing other components in the system to complete the transportation and quantitative spraying of the flocculant.

[0032] The annular tube 703 is a channel for discharging the flocculant, and is connected to the bottom end of the second connecting tube 708. It is usually designed so that the fluid can be evenly distributed and dispersedly sprayed through the nozzle. In the slurry treatment, the design of the annular tube 703 ensures that the flocculant can be effectively sprayed onto the surface of the slurry to promote the occurrence of flocculation reaction. Through the nozzle outside the annular tube 703, the flocculant is sprayed into the slurry in a uniform atomized form. This is to increase the contact area between the flocculant and the slurry, helping the flocculant to work more effectively.

[0033] The flocculant is transported to the inner cavity of the fixed shell 701 through the pump body and the first connecting pipe 707. After the drive motor 702 is started, the screw 704 is driven to rotate, driving the threaded plate 705 to move along the outer surface of the screw, thereby controlling the movement of the movable plate 706. The movement of the movable plate 706 will push the flocculant to be discharged into the annular tube 703 along the second connecting pipe 708, and then evenly sprayed into the slurry through the nozzle of the annular tube 703. Since the length of the threaded plate 705 is fixed, the amount of flocculant sprayed each time is constant, which can ensure that the amount of flocculant added is accurate and controllable. If the amount of flocculant added needs to be changed, it is only necessary to adjust the initial position of the threaded plate 705. This design can adjust the amount of flocculant input according to the concentration and properties of the slurry, thereby optimizing the flocculation effect and improving the recovery rate and concentration effect of ore sorting.

[0034] The bottom end of the mounting shell 3 is movably connected to a rotating rod 801 through a bearing, the bottom end of the rotating rod 801 is fixedly connected to a plurality of scrapers 802 , and the outer side of the scraper 802 is fixedly connected to a fixed tube 803 .

[0035] The other output end of the dual-shaft motor 501 is fixedly connected to the first transmission shaft 401, one end of the first transmission shaft 401 is fixedly connected to the first synchronous wheel 402, the outer side of the first synchronous wheel 402 is connected to the second synchronous wheel 403 through a belt, the outer side of the second synchronous wheel 403 is fixedly connected to the second transmission shaft 404, the bottom of the thickener body 1 is connected to the feed pipe 405, the inner side of the feed pipe 405 is movably connected to the dredging blade 407 through a bearing. A control valve 406 is installed on the outer side of the feed pipe 405, and one end of the second transmission shaft 404 is fixedly connected to one side of the dredging blade 407.

[0036] Specifically, as the other output end of the dual-axis motor 501 rotates, it drives the first transmission shaft 401 to rotate synchronously, thereby driving the first synchronous wheel 402 to rotate. At this time, the second synchronous wheel 403 follows the rotation under the transmission action of the belt, and then the second transmission shaft 404 rotates coaxially, causing the dredging blade 407 to rotate, effectively avoiding the deposition of particles in the slurry in the discharge pipe 405, ensuring the smooth flow of the slurry. This design not only improves the patency and discharge efficiency of the discharge pipe 405, but also reduces equipment failures and downtime caused by blockage, and reduces repair and maintenance costs.

[0037] Working principle: When using the device, first start the driving end of the dual-axis motor 501 to drive the first bevel gear 508 connected thereto to rotate, thereby driving the second bevel gear 509 to mesh and rotate. At this time, the other first bevel gear 508 rotates along with the rotation of the second bevel gear 509, further driving the connecting shaft 502 to rotate coaxially, and driving the turntable 503 to rotate synchronously. At this time, the driving block 504 rotates eccentrically along the outer surface of the driving turntable 503. Since the driving block 504 moves in the groove inside the connecting frame 505, the movable rod 601 drives the rubber piston 605 to move left and right along the inner wall of the fixed cylinder 602 under the traction force of the connecting frame 505. When the rubber piston 605 moves toward the direction of the movable rod 601, the outside air enters the internal cavity of the fixed cylinder 602 through the air inlet pipe 604. When the rubber piston 605 moves in the opposite direction, the air inside the fixed cylinder 602 is discharged into the air jet hole on the outer surface of the air jet pipe 606 through the connecting pipe 603, and the air bubbles are eliminated by the high-pressure airflow. In addition, as the other output end of the dual-axis motor 501 rotates, the first transmission shaft 401 is driven to rotate synchronously, thereby driving the first synchronous wheel 402 to rotate. At this time, the second synchronous wheel 403 rotates along with the belt, and then the second transmission shaft 404 rotates coaxially, so that the dredging blade 407 rotates, effectively preventing the particles in the slurry from being deposited in the discharge pipe 405, and ensuring the smooth flow of the slurry; The rotation of the second bevel gear 509 will drive the connecting member 507 to rotate synchronously, and then drive the rotating rod 801 to rotate, and move the plurality of scrapers 802 along the inner wall of the thickener body 1 to remove the slag on the inner wall of the thickener body 1; The flocculant enters the internal cavity of the fixed shell 701 through the pump body and the first connecting pipe 707. When the interior of the cavity is filled with flocculants, the driving motor 702 is started to drive the driving screw 704 to rotate, so that the threaded plate 705 moves left and right along the outer surface of the driving screw 704, and then drives the movable plate 706 to move synchronously, and the flocculant inside the fixed shell 701 is discharged into the interior of the annular tube 703 through the second connecting pipe 708, and is sprayed out through the nozzle outside the annular tube 703. Since the length of the threaded plate 705 is fixed, the amount of flocculant discharged each time is also fixed, so that quantitative spraying of flocculant is achieved. When the amount of flocculant needs to be changed later, the initial position of the threaded plate 705 can be changed. The amount of flocculant added can be accurately adjusted according to the concentration and properties of the slurry to ensure that it plays the best flocculation role and improve the recovery rate and concentration effect of ore sorting.

[0038] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
