Description

Technical Field

[0001] This utility model relates to the technical field of metallurgical mineral processing, specifically to a defoaming and antifreezing device for the liquid surface of a thickener. Background Technology

[0002] A concentrator is a device used for solid-liquid separation, such as... Figure 1 The main structure of the thickener shown typically consists of a large circular tank 1. Inside the tank is a central shaft 2 and a transmission device 3. The transmission device 3 drives the central shaft 2 to rotate within the tank 1. Radial connecting rods 4 are connected to the sides of the central shaft 2, and scrapers 5 are installed below the connecting rods 4. Furthermore, an overflow device is located at the edge of the tank 1, while a bottom flow discharge device is installed at the center of the bottom.

[0003] The thickener operates on the principle of gravity. During operation, the suspension to be treated slowly flows into tank 1 through the feeding device. Under the continuous pull of gravity, the solid particles in the suspension gradually overcome the resistance of the liquid, slowly sink, and eventually settle to the bottom of the tank.

[0004] During the operation of the thickener, a large amount of foam accumulates on the surface of the liquid in tank 1. If it is not dispersed in time, it will continue to rise and accumulate along the overflow line, affecting the efficiency of the thickener's overflow return water utilization. Simultaneously, with the arrival of winter, the foam and accumulated water on the surface of the liquid in tank 1 freeze rapidly, forming a thick and hard ice layer. This ice layer will affect the normal operation of the thickener. When it is necessary to operate the thickener, the ice layer on the surface of the liquid in the tank must first be broken by external force (such as manually using tools to break it). Utility Model Content

[0005] This invention provides a defoaming and anti-freezing device for the liquid surface of a thickener. It solves the problem in existing technologies where a large amount of foam accumulates on the liquid surface during thickener operation. If not promptly dispersed, this foam will continuously rise and accumulate along the overflow line, affecting the efficiency of the thickener's overflow return water utilization. Furthermore, in winter, the foam and accumulated water on the liquid surface in the tank quickly freeze, forming a thick, hard ice layer. This ice layer affects the normal operation of the thickener. When the thickener needs to be operated, the ice layer on the liquid surface in the tank must first be broken by external force.

[0006] A defoaming and antifreezing device for a liquid level concentrator includes a trolley, a sleeve, a support frame, and a mounting plate. The sleeve is rotatably connected to a central shaft. One end of the support frame is fixedly connected to the sleeve, and the other end is fixedly connected to the trolley. The mounting plate is located at the bottom of the support frame. A defoaming assembly is located at the bottom of the mounting plate. The defoaming assembly includes a rotating shaft and rotating rods. The rotating shaft is vertically rotatable at the bottom of the mounting plate. Several rotating rods are arranged radially on the sides of the rotating shaft. A drive assembly for driving the rotating shaft is located at the top of the mounting plate. Several sets of defoaming assemblies are arranged horizontally at the bottom of the mounting plate. The drive assembly includes sprockets, chains, and a drive component for driving the sprockets. Several sprockets are arranged and coaxially fixedly connected to their corresponding rotating shafts. The chains are connected to the sprockets. The drive component includes a bracket and a drive motor. The bracket is fixedly located at the top of the mounting plate, and the drive motor is fixedly connected to the bracket. The output end of the drive motor is coaxially fixedly connected to the sprockets.

[0007] As a further embodiment of this utility model: a vertical slide rail is fixedly installed at the bottom of the support frame, the mounting plate is slidably connected to the slide rail, and the support frame is provided with an adjustment component for adjusting the height of the mounting plate in the vertical direction. The adjustment component includes a vertical lead screw, a vertical groove is opened on the side of the slide rail, the mounting plate is slidably connected to the groove, the vertical lead screw is rotatably connected to the groove, and the mounting plate has a threaded hole that is threadedly connected to the vertical lead screw. The adjustment component also includes a driven gear and a driving gear, a rotating groove is opened on the side of the slide rail, the driven gear is rotatably connected to the rotating groove, and the driven gear is coaxially fixedly connected to the vertical lead screw. The driving gear is rotatably connected to the support frame, and the driven gear meshes with the driving gear. The adjustment component also includes an adjustment motor, the adjustment motor is fixedly connected to the support frame, and the output end of the adjustment motor is coaxially fixedly connected to the adjustment motor.

[0008] As a further embodiment of this utility model: a vertical guide rod is fixedly provided at the bottom of the support frame, and the mounting plate has a mating hole for sliding connection with the guide rod. A limit ring is fixedly provided at the bottom of the guide rod, and the outer diameter of the limit ring is larger than the inner diameter of the mating hole.

[0009] The advantages of this utility model compared to the prior art are:

[0010] When the concentrator is running and foam accumulates on the liquid surface, the trolley and drive assembly are activated. The trolley moves along the edge of the tank, causing the support frame and mounting plate to rotate around the central axis, thus allowing the defoaming assembly to cover the tank surface. Simultaneously, the drive motor operates, its output driving a sprocket fixed coaxially to it. This sprocket is connected to other sprockets via a chain, causing multiple sprockets to rotate synchronously. Since each sprocket is coaxially fixed to its corresponding shaft, the shaft also rotates along with the sprocket. A rotating rod is fixed radially to the side of the shaft. The rotation of the shaft drives the rotating rod to rotate at high speed, stirring and impacting the foam accumulated on the liquid surface. This mechanical force disperses the foam, preventing it from continuously accumulating along the overflow line, thereby ensuring the efficient utilization of the concentrator's overflow return water.

[0021] The specific embodiments of this utility model are described in detail below, but it should be understood that the protection scope of this utility model is not limited to the specific embodiments.

[0022] First Embodiment

[0023] Please see Figures 1 to 6 As shown, a defoaming and antifreezing device for a liquid level concentrator includes a trolley 6, a sleeve 7, a support frame 8, and a mounting plate 9. The sleeve 7 is rotatably connected to a central shaft 2. One end of the support frame 8 is fixedly connected to the sleeve 7, and the other end of the support frame 8 is fixedly connected to the trolley 6. The mounting plate 9 is located at the bottom of the support frame 8. A defoaming component 10 is provided at the bottom of the mounting plate 9. The defoaming component 10 includes a rotating shaft 11 and rotating rods 12. The rotating shaft 11 is vertically rotatably mounted at the bottom of the mounting plate 9. Several rotating rods 12 are provided and are radially fixedly mounted on the side of the rotating shaft 11. A drive component 13 for driving the rotating shaft 11 to rotate is provided at the top of the mounting plate 9. Several sets of defoaming components 10 are provided and are arranged horizontally at the bottom of the mounting plate 9. The drive assembly 13 includes sprockets 15, chains 14, and a drive component for driving the sprockets 15 to rotate. Several sprockets 15 are provided, each coaxially and fixedly connected to a corresponding rotating shaft 11. The chains 14 are connected in conjunction with the sprockets 15. The drive component includes a bracket 16 and a drive motor 17. The bracket 16 is fixedly mounted on the top of the mounting plate 9, and the drive motor 17 is fixedly connected to the bracket 16. The output end of the drive motor 17 is coaxially and fixedly connected to the sprockets 15.

[0024] When the concentrator is running and foam accumulates on the liquid surface, the trolley 6 and drive assembly 13 are activated. The trolley 6 travels along the edge of the tank 1, causing the support frame 8 and mounting plate 9 to rotate around the central axis 2, thus allowing the defoaming assembly 10 to cover the surface of the tank 1. Simultaneously, the drive motor 17 operates, and its output drives the sprocket 15, which is coaxially fixed to it, to rotate. This sprocket 15 is connected to other sprockets 15 via a chain 14, causing multiple sprockets 15 to rotate synchronously. Since each sprocket 15 is coaxially fixed to its corresponding shaft 11, the shaft 11 also rotates along with the sprocket 15. The rotating rod 12 is radially fixed to the side of the shaft 11. The rotation of the shaft 11 drives the rotating rod 12 to rotate at high speed, stirring and impacting the foam accumulated on the liquid surface. This mechanical force disperses the foam, preventing it from continuously increasing and accumulating along the overflow line, thereby ensuring the utilization efficiency of the concentrator's overflow return water.

[0025] Before winter arrives, start the device. The drive assembly 13 drives the defoaming assembly 10 to operate continuously, constantly stirring and impacting the foam and water on the surface of the condenser liquid. This continuous mechanical movement keeps the liquid in a flowing state, preventing the foam and water from remaining still and freezing on the liquid surface, thus avoiding the formation of a thick and hard ice cap. This ensures that the condenser can operate normally in winter without the need to break the ice cap with external force before starting.

[0026] With multiple sets of horizontally arranged defoaming components 10 working together, the rotating rod 12 generates a powerful mechanical force through high-speed rotation. Compared with the traditional simple water flow impact, it can more effectively break and disperse relatively stable foam, greatly improving the defoaming efficiency and ensuring that the utilization efficiency of the overflow water from the concentrator is not affected by foam accumulation.

[0027] In winter, the continuously operating defoaming component 10 keeps the liquid flowing, effectively preventing foam and accumulated water from freezing into an ice cap. This avoids equipment damage caused by ice caps and the hassle of having to break the ice cap with external force before starting the machine, ensuring the normal operation of the concentrator in the cold season and reducing equipment failure rate and maintenance costs.

[0028] The entire device is connected to the central shaft 2 of the concentrator by rotating the sleeve 7. The trolley 6 is fixed to the sleeve 7 by the support frame 8. The mounting plate 9 is set at the bottom of the support frame 8 and carries the defoaming component 10 and the drive component 13. The structure is compact and stable, easy to install and disassemble, and convenient for later maintenance and repair.

[0029] Second Embodiment

[0030] Based on the first embodiment, a vertical slide rail 18 is fixedly installed at the bottom of the support frame 8. The mounting plate 9 is slidably connected to the slide rail 18. The support frame 8 is provided with an adjustment assembly for adjusting the height of the mounting plate 9 in the vertical direction. The adjustment assembly includes a vertical lead screw 19. A vertical slide groove 20 is opened on the side of the slide rail 18. The mounting plate 9 is slidably connected to the slide groove 20. The vertical lead screw 19 is rotatably connected to the slide groove 20. The mounting plate 9 has a screw hole 21 that is threadedly connected to the vertical lead screw 19. The adjustment assembly also includes a driven gear 22 and a driving gear 23. A rotating groove 24 is opened on the side of the slide rail 18. The driven gear 22 is rotatably connected to the rotating groove 24. The driven gear 22 is coaxially fixedly connected to the vertical lead screw 19. The driving gear 23 is rotatably connected to the support frame 8. The driven gear 22 and the driving gear 23 mesh. The adjustment assembly also includes an adjustment motor 25, which is fixedly connected to the support frame 8, and the output end of the adjustment motor 25 is fixedly connected to the adjustment motor 25 coaxially.

[0031] When it is necessary to adjust the height of the mounting plate 9 in the vertical direction, the adjustment motor 25 is started. The output end of the adjustment motor 25 drives the drive gear 23 to rotate, and the drive gear 23 meshes with the driven gear 22, thereby causing the driven gear 22 to rotate. Since the driven gear 22 is coaxially fixed with the vertical lead screw 19, the vertical lead screw 19 rotates in the rotating groove 24, and the mounting plate 9 is threadedly connected to the vertical lead screw 19 through the screw hole 21, and the mounting plate 9 slides in contact with the sliding groove 20 on the slide rail 18, the mounting plate 9 can move up and down in the vertical direction as the vertical lead screw 19 rotates, thereby adjusting the height of the defoaming component 10.

[0032] The adjusting component can flexibly adjust the height of the defoaming component 10 according to the actual liquid level and foam accumulation in the concentrator, ensuring that the rotating rod 12 is always in the optimal position to agitate and impact the foam, thereby improving the defoaming effect. Simultaneously, the motor-driven adjustment makes operation convenient and quick, adapting to different working conditions and improving the versatility and practicality of the device.

[0033] Third Embodiment

[0034] Based on the second embodiment, a vertically oriented guide rod 26 is fixedly installed at the bottom of the support frame 8, and the mounting plate 9 has a mating hole 27 that is slidably connected to the guide rod 26. A limit ring 28 is fixedly installed at the bottom of the guide rod 26, and the outer diameter of the limit ring 28 is larger than the inner diameter of the mating hole 27.

[0035] During the vertical movement of the mounting plate 9, the guide rod 26 acts as a guide, ensuring that the mounting plate 9 can only move in the vertical direction and will not deviate. The limiting ring 28 is fixed to the bottom of the guide rod 26, and its outer diameter is larger than the inner diameter of the mating hole 27, to prevent the mounting plate 9 from falling off the bottom of the guide rod 26 during movement.

[0036] The guide rod 26 ensures the stability and accuracy of the movement of the mounting plate 9, keeping the defoaming component 10 horizontal during height adjustment and preventing the defoaming effect from being affected by the tilt of the mounting plate 9. The limit ring 28 provides a safety guarantee, preventing the mounting plate 9 from accidentally falling off and causing equipment damage or safety accidents, thus improving the reliability and safety of the device.

[0037] The above-disclosed embodiments are only a few specific examples of the present utility model. However, the embodiments of the present utility model are not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present utility model.
