Description

Technical Field

[0001] This utility model belongs to the field of alkaline solution processing technology, and in particular relates to a high-speed centrifugal defoaming device for alkaline solutions. Background Technology

[0002] In industries such as chemical, printing and dyeing, and papermaking, alkali solutions are widely used. However, alkali solutions are prone to generating a large number of bubbles during production, storage, or processing. These bubbles not only reduce production efficiency and affect product quality, but may also overflow containers, causing environmental pollution or safety hazards. Therefore, a defoaming device is needed to treat the bubbles. Since the liquid level of alkali solutions may change during production due to feeding, discharge, evaporation, or reaction, when the liquid level drops, existing defoaming devices are usually fixed structures and difficult to adjust in height, which may prevent them from effectively contacting and treating the bubbles on the liquid surface, resulting in poor adaptability. Utility Model Content

[0003] The purpose of this invention is to provide a high-speed centrifugal defoaming device for alkaline solutions. By setting an adjustment component, specifically starting a motor to drive a lead screw to rotate inside a slide rail, the lead screw drives a slider to slide on the inner wall of the slide rail, thereby moving the defoaming component through a connecting frame to adapt to different liquid levels of alkaline solutions. This solves the problem that existing defoaming devices are usually fixed structures, making it difficult to adjust the height and resulting in poor adaptability.

[0004] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution: This utility model relates to a high-speed centrifugal defoaming device for alkaline solutions, comprising a defoaming tank, an adjusting component, and a defoaming assembly. The adjusting component is installed on the right side of the defoaming tank and is used to adjust the height of the defoaming assembly. The adjusting component includes: A support plate is fixedly connected to the right side of the defoaming tank via a support block. A slide rail is fixedly connected to the left side of the support plate. A slider is slidably connected to the inner wall of the slide rail. A connecting frame is fixedly connected to the left side of the slider. A driving mechanism is provided for driving a slider to slide on the inner wall of a slide rail. The driving mechanism includes a lead screw, which is rotatably connected inside the slide rail. The outer surface of the lead screw is threadedly connected to the inside of the slider. A motor is fixedly connected to the top of the slide rail, and the bottom output end of the motor is fixedly connected to the top of the lead screw via a coupling. The defoaming component is installed inside the defoaming tank and is used for defoaming alkaline solution bubbles. The defoaming component includes two support frames, which are fixedly connected to the bottom of the connecting frame. A second motor is fixedly connected to the top of the support frame, and a centrifugal impeller is fixedly connected to the bottom output end of the second motor.

[0005] Furthermore, four limiting rods are fixedly connected to the inner wall of the bottom of the defoaming bucket, and the outer surface of each limiting rod is slidably connected to the inside of the support frame.

[0006] Furthermore, the defoaming component also includes: A crushing disc is fixedly connected to the bottom of a support frame and is used to crush air bubbles. A centrifugal impeller is rotatably connected inside the crushing disc. The crushing disc is conical in shape. The feed inlet is fixedly connected to the bottom of the crushing disc via a connecting rod, and is used to guide air bubbles into the interior of the crushing disc.

[0007] Furthermore, the inner wall of the crushing disc is fixedly connected with several serrations.

[0008] Furthermore, a grid is fixedly connected to the bottom of the feed inlet.

[0009] Furthermore, a spiral guide groove is fixedly connected to the inner wall of the feed inlet.

[0010] This utility model has the following beneficial effects: 1. This utility model, by setting an adjustment component, specifically starts a motor to drive a lead screw to rotate inside the slide rail. At this time, the lead screw drives a slider to slide on the inner wall of the slide rail, thereby driving the defoaming component to move through the connecting frame, adapting to different alkaline liquid levels and improving the adaptability of the device.

[0011] 2. This utility model, by setting a feed inlet, specifically a grid at the bottom of the feed inlet, prevents large impurities or solid particles from entering the crushing disc area, and can initially decompose large bubble clusters. Then, the bubbles enter the interior of the crushing disc through the spiral guide groove. The spiral guide groove extends the flow path of the bubbles, reduces droplet entrainment, and improves the crushing efficiency of the bubbles.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0017] Please see Figures 1-5 As shown, this utility model has the following two specific embodiments.

[0018] Example 1 This utility model relates to a high-speed centrifugal defoaming device for alkaline solutions, comprising a defoaming tank 1, an adjusting component 2, and a defoaming component 3. The adjusting component 2 is installed on the right side of the defoaming tank 1 and is used to adjust the height of the defoaming component 3. The adjusting component 2 includes: Support plate 21 is fixedly connected to the right side of defoaming tank 1 via support block. Slide rail 211 is fixedly connected to the left side of support plate 21. Slider 212 is slidably connected to the inner wall of slide rail 211. Connecting bracket 22 is fixedly connected to the left side of slider 212. A drive mechanism is used to drive the slider 212 to slide on the inner wall of the slide rail 211. The drive mechanism includes a lead screw 213, which is rotatably connected inside the slide rail 211. The outer surface of the lead screw 213 is threadedly connected to the inside of the slider 212. A motor 214 is fixedly connected to the top of the slide rail 211. The bottom output end of the motor 214 is fixedly connected to the top of the lead screw 213 through a coupling. The defoaming component 3 is installed inside the defoaming tank 1 and is used for defoaming alkaline solution bubbles. The defoaming component 3 includes two support frames 31, which are fixedly connected to the bottom of the connecting frame 22. A second motor 311 is fixedly connected to the top of the support frame 31, and a centrifugal impeller 312 is fixedly connected to the bottom output end of the second motor 311.

[0019] like Figures 1-2 As shown, by setting the adjustment component 2, specifically starting the motor 214, the lead screw 213 is driven to rotate inside the slide rail 211. At this time, the lead screw 213 drives the slider 212 to slide on the inner wall of the slide rail 211, thereby driving the defoaming component 3 to move through the connecting frame 22, adapting to different alkaline liquid levels and improving the adaptability of the device.

[0020] Four limiting rods 313 are fixedly connected to the inner wall of the bottom of the defoaming tank 1. The outer surface of the limiting rods 313 is slidably connected to the inside of the support frame 31.

[0021] The four limit rods 313 slide in cooperation with the support frame 31, providing additional lateral support and guidance when the defoaming component 3 is raised, lowered and operated, effectively preventing shaking and swaying, and ensuring operational stability and safety.

[0022] Example 2 The difference from Embodiment 1 is that this embodiment discloses a crushing disc 32 and a feed inlet 33: Defoaming component 3 also includes: The crushing disc 32 is fixedly connected to the bottom of the support frame 31 and is used to crush air bubbles. The centrifugal impeller 312 is rotatably connected inside the crushing disc 32. The crushing disc 32 is conical in shape. The feed inlet 33 is fixedly connected to the bottom of the crushing disc 32 by a connecting rod, and is used to guide air bubbles into the interior of the crushing disc 32.

[0023] The inner wall of the crushing disc 32 is fixedly connected with several serrations 321.

[0024] A grid 331 is fixedly connected to the bottom of the feed inlet 33.

[0025] A spiral guide groove 332 is fixedly connected to the inner wall of the feed inlet 33.

[0026] like Figures 3-5 As shown, the conical crushing disc 32 is designed to effectively guide the crushed bubbles back to the defoaming tank 1. The serrations 321 enhance the shearing force of the crushing disc 32. By setting the feed inlet 33, specifically the grid 331 at the bottom of the feed inlet 33, large impurities or solid particles are prevented from entering the crushing disc 32 area, and large bubble clusters can be initially decomposed. Then, the bubbles enter the interior of the crushing disc 32 through the spiral guide groove 332. The spiral guide groove 332 extends the bubble flow path, reduces droplet entrainment, and improves the bubble crushing efficiency.

[0027] A specific application of this embodiment is as follows: During use, the height of the defoaming component 3 is adjusted according to the liquid level in the defoaming tank 1. Motor 1 214 is started, driving the lead screw 213 to rotate inside the slide rail 211. At this time, the lead screw 213 drives the slider 212 to slide on the inner wall of the slide rail 211, thereby moving the defoaming component 3 through the connecting frame 22. Simultaneously, the support frame 31 slides on the outer surface of the limiting rod 313, providing a stable trajectory for the movement of the support frame 31. Motor 2 311 is started, driving the centrifugal impeller 312 to rotate, performing the defoaming operation. Due to the centrifugal force of the centrifugal impeller 312... The action drives the bubbles to move towards the center. The grid 331 at the bottom of the feed inlet 33 prevents large impurities or solid particles from entering the crushing disc 32 area and can initially decompose large bubble clusters. Then, the bubbles enter the interior of the crushing disc 32 through the spiral guide groove 332. The spiral guide groove 332 extends the bubble flow path and reduces droplet entrainment. After entering the interior of the crushing disc 32, the bubbles are thrown to the inner wall of the crushing disc 32 by the centrifugal impeller 312. After the bubbles are broken into liquid, due to the conical design of the crushing disc 32, the liquid is guided back to the interior of the defoaming tank 1. The inner wall of the crushing disc 32 is provided with serrations 321, which improves the shearing force of the crushing disc 32.
