Description

Technical Field

[0001] This utility model relates to the field of alkaline defoaming technology, and in particular to a foam elimination device. Background Technology

[0002] During the alkaline solution circulation cleaning process of cold-rolled strip steel, a large amount of foam is generated, and the resulting overflow often occurs, causing significant impact on the site. Therefore, a foam elimination device is needed. In existing technologies, defoaming techniques are divided into chemical defoaming and physical defoaming. The principle of physical defoaming is to change the viscosity or physical properties of the foam to cause it to break down, while maintaining the chemical composition of the foam.

[0003] In existing technologies, while closed-type foam elimination reservoirs can prevent foam overflow, they also enclose the defoaming equipment inside the tank, making it difficult for users to see the height of the defoamer inside the tank and to adjust its height according to the volume of liquid inside the tank. Therefore, those skilled in the art have provided a foam elimination device to solve the problems mentioned in the background art. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a foam elimination device. When using this device, the user can adjust the height of the defoamer to ensure that the defoamer is in close contact with the surface of the liquid. This is beneficial even when there is a small amount of liquid. Furthermore, the user can easily control the height of the defoamer by using a pointer and a level gauge when adjusting the height.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a foam elimination device, comprising a defoaming device, a tank, a bottom plate, a protective bracket, and a level gauge. The defoaming device includes a rotating drum, a fourth bracket, and a fifth bracket. A hydraulic cylinder is fixedly installed inside the fourth bracket. A rotating shaft is rotatably installed at the lower end of the hydraulic cylinder. A defoaming machine is fixedly installed at the lower end of the rotating shaft. The rotating shaft is slidably engaged inside the rotating drum.

[0006] A motor is fixedly installed inside the fifth bracket, and a second gear is fixedly installed at the output end of the motor. A first gear is fixedly installed at the upper end of the rotating drum, and the first gear meshes with the second gear. A third bracket is fixedly installed around the output end of the oil cylinder. Two pointers are fixedly installed at the lower end of one side of the third bracket, and two counterweights are fixedly installed at the other end of the third bracket. The height of the two pointers is the same as the height of the defoamer.

[0007] Furthermore, the tank body is fixedly installed on the upper end of the base plate, and two No. 1 brackets are fixedly installed on both sides of the upper end of the base plate.

[0008] Furthermore, a level gauge is fixedly installed at the front end of the tank, and a protective bracket is fixedly installed around the level gauge. The two pointers are respectively slidably installed inside the two sides of the protective bracket.

[0009] Furthermore, an exhaust port is fixedly provided at the upper front end of the tank body, and a rinsing port is fixedly provided at the front end of the tank body.

[0010] Furthermore, a drain outlet is fixedly provided on the lower rear side of the tank body, and a foam inlet is fixedly provided on the upper rear side of the tank body.

[0011] Furthermore, a return port is fixedly provided on the lower rear side of the tank body, and two No. 2 brackets are fixedly provided on the upper end of the bottom plate near the control box. A return pump is fixedly provided on the upper end of the two No. 2 brackets, and the return port is connected to the return pump.

[0012] Furthermore, both the fourth and fifth supports are fixedly installed at the upper end of the tank, and the rotating drum is rotatably installed inside the upper end of the tank.

[0013] This utility model has the following beneficial effects:

[0014] 1. This utility model proposes a foam elimination device. During use, a motor drives a second gear to rotate, which in turn drives a first gear to rotate. The first gear then drives a rotating drum, which in turn drives a rotating shaft and the defoamer to rotate, thus facilitating foam elimination. Simultaneously, the user controls a hydraulic cylinder to move the cylinder up and down, allowing for height adjustment of the defoamer. The user can adjust the height of the defoamer according to the volume of liquid inside the tank, improving practicality. Furthermore, when adjusting the height, the hydraulic cylinder also moves a third support bracket, which in turn moves a pointer. The pointer's height matches the height of the defoamer, allowing the user to check the liquid volume inside the tank using a level gauge and the pointer, thus adjusting the defoamer's height and preventing it from being adjusted too high or too low.

[0015] 2. The foam elimination device proposed in this utility model has a tank body that is fixed horizontally. This makes it less likely to get clogged during use and makes it more convenient to discharge waste. Furthermore, when placed horizontally, the speed at which the foam rises is slowed down due to the overall surface of the device. The air inside the tank is discharged through the exhaust port, creating a negative pressure state inside the tank, which helps the foam to enter the tank without the need for an additional pump.

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 protection scope of the present utility model.

[0024] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 An embodiment of this utility model provides a foam elimination device, including a defoaming device 1, a tank 3, a base plate 4, a protective bracket 13, and a level gauge 14. The tank 3 is fixedly installed on the upper end of the base plate 4. Two No. 1 brackets 8 are fixedly installed on both sides of the upper end of the base plate 4. The level gauge 14 is fixedly installed at the front end of the tank 3. The protective bracket 13 is fixedly installed around the level gauge 14. An exhaust port 2 is fixedly installed at the upper end of the front end of the tank 3. A rinsing port 5 is fixedly installed at the front end of the tank 3. A drain port 9 is fixedly installed at the lower rear end of the tank 3. A foam inlet 6 is fixedly installed at the upper rear end of the tank 3. A return port 10 is fixedly installed at the lower rear end of the tank 3. Two No. 2 brackets 12 are fixedly installed on the upper end of the side of the base plate 4 near the control box 7. A return pump 11 is fixedly installed at the upper end of the two No. 2 brackets 12. The return port 10 is connected to the return pump 11.

[0025] Specifically, the level gauge 14 allows users to observe the liquid level inside the tank 3, facilitating the adjustment of the defoamer 112's height; the protective bracket 13 protects the defoamer 112 while limiting the pointer 101; the drain port 9 facilitates wastewater discharge; the foam inlet 6 allows foam to enter the tank 3; the return pump 11 transports the liquefied foam back to the circulation tank from the return port 10; and the exhaust port 2 removes air from inside the tank 3, creating a negative pressure state inside the tank 3, which facilitates foam entry into the tank 3 without the need for an additional pump.

[0026] Reference Figure 3 and Figure 4 The defoaming device 1 includes a rotating drum 105, a fourth support 106, and a fifth support 109. A hydraulic cylinder 107 is fixedly installed inside the fourth support 106. A rotating shaft 111 is rotatably mounted at the lower end of the hydraulic cylinder 107. A defoaming machine 112 is fixedly mounted at the lower end of the rotating shaft 111. The rotating shaft 111 is slidably engaged inside the rotating drum 105. A motor 108 is fixedly installed inside the fifth support 109. A second gear 110 is fixedly mounted at the output end of the motor 108. A first gear 104 is fixedly mounted at the upper end of the rotating drum 105. 4 meshes with gear 110. A support 102 is fixedly installed around the output end of the cylinder 107. Two pointers 101 are fixedly installed on the lower end of one side of the support 102. Two counterweights 103 are fixedly installed on the other end of the support 102. The height of the two pointers 101 is the same as the height of the defoamer 112. Supports 106 and 109 are fixedly installed on the upper end of the tank 3. The rotating drum 105 is rotatably installed inside the upper end of the tank 3. The two pointers 101 are slidably installed inside the two sides of the protective support 13 respectively.

[0027] Specifically, the hydraulic cylinder 107 drives the rotating shaft 111 to move up and down, which helps the user adjust the height of the defoamer 112 so that it fits against the surface of the liquid. The motor 108 drives the second gear 110 to rotate, which in turn drives the first gear 104 and the rotating drum 105 to rotate, thereby rotating the rotating shaft 111 and the defoamer 112. This allows the motor 108 to be installed on one side of the rotating shaft 111, leaving the upper part of the rotating shaft 111 free for the installation of the hydraulic cylinder 107, thus adjusting the height of the defoamer 112. The pointer 101 allows the user to check the height of the defoamer 112 inside the tank 3. The counterweight 103 helps to balance the weight of the third support 102, and the rotating drum 105 allows the rotating shaft 111 to move up and down while also sliding up and down.

[0028] Working principle: When in use, the motor 108 drives the second gear 110 to rotate, which in turn drives the first gear 104 and the rotating drum 105 to rotate. The rotating drum 105 drives the rotating shaft 111 to rotate, which in turn drives the defoamer 112 to rotate. As the defoamer 112 rotates, it breaks up the foam at the bottom. The user can control the oil cylinder 107 to move the rotating shaft 111 up and down to adjust the height of the defoamer 112. While the oil cylinder 107 is running, it also drives the third support 102 to move, which in turn drives the pointer 101 to move. This allows the user to check the height of the defoamer 112 inside the tank 3 and adjust it to the appropriate height.
