Description

Technical Field

[0001] This utility model relates to the technical field of water-reducing agent production equipment, specifically to a foam control device for water-reducing agent production. Background Technology

[0002] During the production of water-reducing agents, the mixing and chemical reaction of raw materials in the reactor will generate a large amount of foam. If this foam is not dealt with in time, it will have a significant impact on production efficiency and product quality.

[0003] Traditional mechanical defoaming devices are mostly fixed installation structures, which cannot dynamically adjust their position according to the height of the foam layer. When the height of the foam layer changes, the defoaming components are prone to deviating from the working area, resulting in a significant decrease in defoaming efficiency. Utility Model Content

[0004] The purpose of this invention is to provide a foam control device for the production of water-reducing agents, so as to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A foam control device for water-reducing agent production includes a reaction vessel body, a tank cover fixedly installed on the top of the reaction vessel body, a drive motor fixedly connected to the top of the tank cover, a rotating column fixedly connected to the output end of the drive motor, a stirring rack fixedly installed on the outside of the rotating column, discharge pipes fixedly installed at both ends of the top of the tank cover, and air pumps fixedly installed on both sides of the reaction vessel body. Also includes: The height adjustment mechanism is located at the top of the inner wall of the reactor body and uses a telescopic mechanism to adapt to the height of the water-reducing agent liquid level. The defoaming mechanism is located at the bottom inside the height adjustment mechanism and is used for mechanical cutting and pressing to quickly break up the foam and reduce the amount of defoamer used.

[0006] A further improvement of the present invention is that the height adjustment mechanism includes a fixed frame, a sliding rod is fixedly connected to the bottom of the fixed frame, a base frame is fixedly connected to the bottom of the sliding rod, connecting plates are fixedly installed at both ends of the inner side of the base frame, a threaded screw is movably connected to the top of the connecting plate, a power motor is fixedly installed at the top of the threaded screw, a fixed plate is fixedly sleeved at the bottom of the power motor, and the side of the fixed plate is fixedly connected to the inner side of the fixed frame.

[0007] A further improvement of the present invention is that the defoaming mechanism includes a defoaming plate and a rotating column. The outer side of the rotating column is fixedly installed inside the defoaming plate, and a toothed block is fixedly installed on the other side of the defoaming plate. Support plates are movably connected to both ends of the rotating column.

[0008] A further improvement of this utility model is that: movable blocks are fixedly sleeved on the outer sides of both ends of the defoaming board, and a lifting column is movably connected to the bottom of the movable block, with the bottom of the lifting column fixedly installed inside the support plate.

[0009] A further improvement of this utility model is that: telescopic rods are fixedly installed at both ends of the inner cavity of the connecting plate, and a moving block is fixedly connected to the telescopic end of the telescopic rod, with the front side of the moving block fixedly connected to one end of the support plate.

[0010] A further improvement of this utility model is that: spray frames are fixedly connected to both ends of the inner side of the base frame, and nozzles are fixedly installed inside the spray frames.

[0011] A further improvement of this utility model is that: a connecting hose is fixedly connected to the inlet of the nozzle, and the other end of the connecting hose is fixedly connected to the output end of the air pump.

[0012] Due to the adoption of the above technical solution, the technological progress achieved by this utility model compared to the prior art is as follows: 1. This utility model provides a foam control device for water-reducing agent production. Through height adaptability, the adjustment mechanism is driven by a power motor to rotate a threaded screw. The screw engagement converts the rotational motion into linear up-and-down movement of the connecting plate along the slide rod, achieving precise overall lifting and lowering of the defoaming mechanism. The telescopic rod inside the connecting plate pushes the moving block, causing the support plate to adjust laterally. This allows the toothed blocks on the side of the defoaming plate to move, collide, and cut the foam. Simultaneously, the fine-tuning structure composed of the movable block and the lifting column can flexibly change the tilt angle of the defoaming plate according to the foam layer thickness, allowing the rotating defoaming plate to generate downward pressure, forcibly pressing the foam into the liquid phase material. The impact force of the liquid further breaks up the foam, improving the thoroughness of defoaming and reducing foam residue.

[0013] 2. This utility model provides a foam control device for the production of water-reducing agents. It generates airflow through an air pump and nozzle, and uses the impact force of the airflow to directly break the foam and loosen the dense foam structure. This causes the foam to have an opposing force with the defoaming board, thereby better cutting the foam and avoiding the problem of the water-reducing agent performance being affected by excessive addition of defoamer, thus ensuring the stability of product quality.

[0016] The present invention will be further described in detail below with reference to embodiments: like Figure 1-5 As shown, this utility model has the following three specific embodiments.

[0017] Example 1 This utility model provides a foam control device for water-reducing agent production, including a reaction vessel body 1, a tank cover 2 fixedly installed on the top of the reaction vessel body 1, a drive motor 4 fixedly connected to the top of the tank cover 2, a rotating column 11 fixedly connected to the output end of the drive motor 4, a stirring rack 12 fixedly installed on the outside of the rotating column 11, a discharge pipe 3 fixedly installed at both ends of the top of the tank cover 2, and an air pump 5 fixedly installed on both sides of the reaction vessel body 1. Also includes: The height adjustment mechanism is located at the top of the inner wall of the reactor body 1. It uses a telescopic mechanism to adjust the height of the water-reducing agent liquid level. The defoaming mechanism is located at the bottom inside the height adjustment mechanism. It is used for mechanical cutting and pressing to quickly break up the foam and reduce the amount of defoamer used.

[0018] like Figure 1 , 2As shown, when the reactor body 1 starts production, the raw materials enter the reactor through the discharge pipe 3 at the top of the tank cover 2. The drive motor 4 drives the rotating column 11 and the outer stirring rack 12 to rotate, mixing and stirring the materials. During the processing, the foam generated by the reaction of the raw materials and the air introduced by the stirring gradually accumulates. At this time, the device enters the foam control stage. With the adaptation adjustment of the height adjustment mechanism, the telescopic mechanism drives the defoaming mechanism to move up and down. When the foam layer is thick, the mechanism extends, causing the defoaming mechanism to move down to the upper part of the foam layer. When the foam decreases or the liquid level drops, the mechanism contracts, causing the defoaming mechanism to move up, ensuring that the defoaming component always acts on the foam concentration area, avoiding ineffective operation or interference with the stirring rack 12. The drive component of the defoaming mechanism is activated, driving the serrated component to move, cutting and destroying the surface tension of the foam, greatly reducing the dependence on defoamer and avoiding excessive addition that affects the performance of the water-reducing agent.

[0019] Example 2 The difference from Embodiment 1 is that this embodiment discloses a fixed frame 13, a defoaming plate 174, and a rotating column 173. The height adjustment mechanism includes the fixed frame 13, with a sliding rod 14 fixedly connected to the bottom of the fixed frame 13, a base frame 15 fixedly connected to the bottom of the sliding rod 14, connecting plates 17 fixedly installed at both ends of the inner side of the base frame 15, a threaded screw 16 movably connected to the top of the connecting plate 17, a power motor 18 fixedly installed at the top of the threaded screw 16, a fixed plate 19 fixedly sleeved at the bottom of the power motor 18, and the side of the fixed plate 19 fixedly connected to the inner side of the fixed frame 13. The defoaming mechanism includes the defoaming plate 174 and... A rotating column 173 is fixedly installed on the outside of the defoaming plate 174 inside. A toothed block is fixedly installed on the other side of the defoaming plate 174. Support plates 172 are movably connected to both ends of the rotating column 173. Movable blocks 176 are fixedly sleeved on the outside of both ends of the defoaming plate 174. A lifting column 177 is movably connected to the bottom of the movable block 176. The bottom of the lifting column 177 is fixedly installed inside the support plate 172. Telescopic rods 175 are fixedly installed at both ends of the inner cavity of the connecting plate 17. A moving block 171 is fixedly connected to the telescopic end of the telescopic rod 175. The front side of the moving block 171 is fixedly connected to one end of the support plate 172.

[0020] like Figure 2 , 3As shown in Figure 4, the entire adjustment mechanism is fixed to the top of the inner wall of the reactor body 1. When it is necessary to adapt to foam layers of different heights, the power motor 18 is started, and its output shaft drives the threaded screw 16 to rotate. Since the threaded screw 16 and the connecting plate 17 form a threaded engagement, the rotational motion of the threaded screw 16 is converted into the vertical linear motion of the connecting plate 17 along the slide bar 14. The fixed plate 19 ensures the stable rotation of the threaded screw 16 by fixing the position of the power motor 18, which ultimately drives the defoaming mechanism connected below the connecting plate 17 to rise and fall as a whole, accurately aligning with the height of the foam layer. When the defoaming mechanism is activated, firstly, the telescopic rod 175 inside the connecting plate 17 extends and retracts, pushing the moving block 171 to move horizontally, which in turn drives the support plate 172 to adjust its lateral position, causing the toothed blocks on the side of the defoaming plate 174 to move, collide, and cut the foam, thus breaking the surface tension of the foam. At the same time, the fine-tuning structure composed of the movable block 176 and the lifting column 177 can finely adjust the tilt angle of the defoaming plate 174 according to the thickness of the foam layer. By extending and retracting the lifting column 177, the height of the movable block 176 is changed, causing the rotating defoaming plate 174 to generate downward pressure, forcibly pressing the foam into the liquid phase material, and using the liquid impact force to further break the foam.

[0021] Example 3 The difference from Embodiment 2 is that this embodiment discloses a nozzle 152 and an air pump 5. The two ends of the inner side of the base frame 15 are fixedly connected to a spray frame 151. The nozzle 152 is fixedly installed inside the spray frame 151. The inlet of the nozzle 152 is fixedly connected to a connecting hose 153. The other end of the connecting hose 153 is fixedly connected to the output end of the air pump 5.

[0022] like Figure 5 As shown, when the height adjustment mechanism positions the defoaming mechanism to the corresponding position of the foam layer, the spray frames 151 at both ends of the inner side of the base frame 15 start working simultaneously. The high-pressure airflow generated by the air pump 5 is delivered to the inside of the spray frame 151 through the connecting hose 153, and forms multiple directional airflows through the nozzles 152 to be sprayed onto the foam layer. On the one hand, the airflow impact can directly break the stability of the foam, making the originally dense foam structure loose, which is convenient for the teeth of the defoaming plate 174 to cut. On the other hand, the airflow forms an upward lifting force in the foam layer and counteracts the defoaming plate 174, causing the foam to deform and break during the stress process, accelerating the penetration of the foam into the liquid phase material, and realizing the all-round treatment of the foam in the reactor.

[0023] The working principle of the foam control device used in the production of this water-reducing agent will be explained in detail below.

[0024] like Figure 1-5As shown, when the reactor body 1 starts production, the raw materials enter the reactor through the discharge pipe 3 at the top of the tank cover 2. The drive motor 4 drives the rotating column 11 and the outer stirring frame 12 to rotate, mixing and stirring the materials. During the processing, foam generated by the reaction of the raw materials and the air introduced by the stirring gradually accumulates. At this time, the device enters the foam control stage. With the adaptation adjustment of the height adjustment mechanism, the telescopic mechanism drives the defoaming mechanism to move up and down. When the foam layer is thick, the mechanism extends, causing the defoaming mechanism to move down to the upper part of the foam layer; when the foam decreases or the liquid level drops, the mechanism contracts, causing the defoaming mechanism to move up, ensuring that the defoaming components are always in good working order. When the defoaming mechanism is activated in the area where foam is concentrated, the telescopic rod 175 inside the connecting plate 17 extends and retracts, pushing the moving block 171 to move horizontally. This, in turn, drives the support plate 172 to adjust its lateral position, causing the toothed blocks on the side of the defoaming plate 174 to move, collide, and cut the foam, thus breaking the surface tension of the foam. At the same time, the fine-tuning structure composed of the movable block 176 and the lifting column 177 can finely adjust the tilt angle of the defoaming plate 174 according to the thickness of the foam layer. The extension and retraction of the lifting column 177 changes the height of the movable block 176, causing the rotating defoaming plate 174 to generate downward pressure, forcibly pressing the foam into the liquid phase material, and further breaking the foam by using the liquid impact force.

[0025] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
