Description

Technical Field

[0001] This utility model relates to the technical field of defoamer dispersion devices, specifically a dispersion device for defoamers. Background Technology

[0002] Defoamers are substances that reduce the surface tension of water, solutions, suspensions, etc., preventing foam formation or reducing or eliminating existing foam. Defoamers have a wide range of applications, such as in the food industry, paper industry, water treatment, oil extraction industry, printing and dyeing industry, coating industry, detergent industry, rubber latex industry, aerosol industry, daily chemical industry, pharmaceutical industry, and dairy industry. Defoamers are usually surfactants, and their core function is to reduce the surface tension of liquids. Defoamers need to be dispersed in the foam system to work effectively. If they are not dispersed evenly, surfactant molecules cannot fully contact the foam surface, resulting in insignificant reduction in local surface tension and failure to effectively disrupt foam stability. The device used to disperse defoamers is called a defoamer dispersion device.

[0003] Currently, in existing technologies, defoamers are usually dissolved in 5-10 times their volume of water and mixed using a stirring device. The diluted defoamer solution is then introduced into the foam system. However, traditional stirring devices cannot quickly and evenly dissolve and disperse the defoamer into the foam system, resulting in low dispersion efficiency. Therefore, a dispersion device for defoamers is needed. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the existing defoamer devices use traditional stirring devices for mixing, which leads to low defoamer dispersion efficiency. This utility model proposes a dispersion device for defoamers.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a dispersion device for defoamer, including a mixing tank, a first motor is provided on the top of the mixing tank, the output end of the first motor passes through the inner cavity of the mixing tank and is fixedly connected to a stirring shaft, and an intermittent feeding mechanism is provided on one side of the top of the mixing tank. The intermittent feeding mechanism includes a feeding hopper, which is located at the top of the mixing tank. Feeding pipes are provided on both sides of the bottom of the feeding hopper. One end of the feeding pipe is connected to the feed pipe and extends into the inner cavity of the mixing tank. A piston rod is slidably connected to the inner cavity of the feed pipe. A crankshaft is provided at the top of the piston rod. A connecting shaft is fixedly connected to the opposite side of the crankshaft. A rotating shaft is rotatably connected to one end of the crankshaft. A second motor is fixedly connected to the top of the mixing tank, and the second motor drives the rotating shaft to rotate.

[0006] Preferably, a fixing frame is fixedly connected to the top of the mixing tank, and the feed hopper is fixedly connected to the top of the fixing frame.

[0007] Preferably, a partition is fixedly connected to the bottom of the inner wall of the feed hopper, and one end of the feeding pipe passes through the bottom of the feed hopper and is close to the partition.

[0008] Preferably, a valve port is provided on the inner wall of the feed pipe near the bottom of the feed pipe, and the piston rod cooperates with the valve port to open and close.

[0009] Preferably, the crankshaft outer wall is rotatably connected to a hinge shaft, one end of which is rotatably connected to the top of the piston rod.

[0010] Preferably, a fixed sleeve is rotatably connected to the end of the rotating shaft, and the fixed sleeve is fixedly connected to one end of the mixing tank.

[0011] Preferably, the output end of the second motor is fixedly connected to a first gear, and the outer wall of the rotating shaft is fixedly connected to a second gear, with the first gear meshing with the second gear.

[0012] The advantages of this utility model are: This invention introduces the defoamer solution into the feed hopper, and then into the feed pipe via the feeding pipe. A piston rod inside the feed pipe reciprocates up and down, causing the defoamer solution to intermittently enter the mixing tank through the feed pipe. Water is then introduced into the mixing tank, and a first motor drives the stirring shaft for stirring. Combined with the intermittent feeding mechanism, the defoamer solution is fed in intermittently while stirring. Each small amount of defoamer solution disperses more quickly in the water, thus improving the defoamer dispersion efficiency and solving the problem of low defoamer dispersion efficiency caused by traditional stirring devices in existing defoamer devices.

Detailed Implementation

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. This application discloses a dispersing device for defoamers. (Refer to...) Figures 1-5 A dispersion device for defoamer includes a mixing tank 1. A first motor 2 is installed on the top of the mixing tank 1. The output end of the first motor 2 extends through the inner cavity of the mixing tank 1 and is fixedly connected to a stirring shaft 21. An intermittent feeding mechanism 3 is installed on one side of the top of the mixing tank 1. Water is introduced into the mixing tank 1, and defoamer solution is introduced into the intermittent feeding mechanism 3. The stirring shaft 21 is driven by the motor to stir inside the mixing tank 1. The intermittent feeding delivers a small amount of defoamer solution each time, so that the defoamer solution can be dispersed in water more quickly, thereby achieving the purpose of improving the dispersion efficiency of the defoamer. The intermittent feeding mechanism 3 includes a feed hopper 31, which is located at the top of the mixing tank 1. Feed pipes 34 are provided on both sides of the bottom of the feed hopper 31. A feed pipe 35 is provided at one end of each feed pipe 34, extending into the inner cavity of the mixing tank 1. A piston rod 37 is slidably connected to the inner cavity of the feed pipe 35. A crankshaft 315 is located at the top of the piston rod 37. A connecting shaft 314 is fixedly connected to the opposite side of the crankshaft 315. A rotating shaft 311 is rotatably connected to one end of the crankshaft 315. A second motor 38 is fixedly connected to the top of the mixing tank 1, driving the rotating shaft 311. The defoamer is introduced into the feed hopper 31 by rotation. The defoamer flows into the feed pipes 35 on both sides through the two feed pipes 34. The piston rod 37 in the feed pipe 35 moves up and down, so that the defoamer solution flows into the mixing tank 1 intermittently through the two feed pipes 35. The second motor 38 drives the rotating shaft 311 to rotate, and the rotating shaft 311 drives the crankshaft 315 to rotate. The two crankshafts 315 rotate simultaneously with the connecting shaft 314. The crankshafts 315 drive the piston rod 37 to move up and down, so that the defoamer solution can be intermittently fed into the two feed pipes 35.

[0018] Reference Figure 1 , Figure 2 , Figure 3 and Figure 5 A fixed frame 33 is fixedly connected to the top of the mixing tank 1. The feed hopper 31 is fixedly connected to the top of the fixed frame 33. A partition 32 is fixedly connected to the bottom of the inner wall of the feed hopper 31. One end of the feeding pipe 34 passes through the bottom of the feed hopper 31 and is close to the partition 32. A valve port 36 is provided on the inner wall of the feed pipe 35 near the bottom of the feed pipe 34. The piston rod 37 cooperates with the valve port 36 to open and close. The defoamer solution is divided into two parts by the partition 32. The defoamer solution in the feed hopper 31 is fed from both sides. The defoamer solution flows into the two feed pipes 35 through pipe 34. When the piston rod 37 and valve port 36 are closed, the defoamer solution is blocked in the upper part of the feed pipe 35. When the piston rod 37 moves upward and opens with valve port 36, the defoamer solution flows into the mixing tank 1 through valve port 36. This allows the two feed pipes 35 to intermittently feed the defoamer solution. The stirring shaft 21 is driven by the first motor 2 to stir, which can make the small amount of defoamer solution disperse more quickly in the water, thereby improving the dispersion efficiency of the defoamer solution.

[0019] Reference Figure 3 and Figure 4A hinge shaft 313 is rotatably connected to the outer wall of the crankshaft 315. One end of the hinge shaft 313 is rotatably connected to the top of the piston rod 37. A fixed sleeve 312 is rotatably connected to the end of the rotating shaft 311. The fixed sleeve 312 is fixedly connected to one end of the mixing tank 1. A first gear 39 is fixedly connected to the output end of the second motor 38. A second gear 310 is fixedly connected to the outer wall of the rotating shaft 311. The first gear 39 meshes with the second gear 310. The second motor 38 drives the first gear 39 to rotate. The first gear 39 drives the second gear 310 to rotate. The second gear 310 drives the rotating shaft 311 to rotate. The rotating shaft 311 rotates stably in the inner cavity of the fixed sleeve 312. The rotation of the rotating shaft 311 drives the crankshaft 315 to rotate. The two crankshafts 315 rotate synchronously with the connecting shaft 314. The rotation of the crankshaft 315 drives the piston rod 37 to slide up and down reciprocally using the hinge shaft 313, so that the piston rod 37 can move up and down reciprocally.

[0020] Working principle: During use, water is introduced into the mixing tank 1, and the defoamer solution is introduced into the intermittent feeding mechanism 3. The first motor 2 drives the stirring shaft 21 to stir inside the mixing tank 1. The defoamer solution is introduced into the feed hopper 31 on the fixed frame 33. The defoamer solution is divided into two parts by the partition 32 and flows into the two feed pipes 35 from the feed pipes 34 on both sides. When the piston rod 37 and the valve port 36 are closed, the defoamer solution stays at the upper part of the feed pipe 35. When the piston rod 37 and the valve port 36 are opened, the defoamer solution flows into the mixing tank 1 through the valve port 36. The second motor 3... The first gear 39 is driven to rotate, and the second gear 310 drives the rotating shaft 311 to rotate. The rotating shaft 311 rotates stably in the inner cavity of the fixed sleeve 312. At the same time, the rotating shaft 311 drives the crankshaft 315 to rotate. The two crankshafts 315 rotate simultaneously with the connecting shaft 314. The crankshafts 315 drive the piston rod 37 to slide up and down through the hinge shaft 313, so that the two feed pipes 35 can intermittently feed the defoamer solution, thereby enabling the defoamer solution to disperse faster and thus achieving the purpose of improving the defoamer dispersion efficiency.
