Description

Technical Field

[0001] The utility model provides a defoaming device for surfactant production, belonging to the technical field of surfactant production. Background Art

[0002] Surfactants are a class of chemicals widely used in the chemical industry, household products, and other fields. Their production process often generates large amounts of bubbles. If these bubbles are not removed promptly, they can affect product quality and production efficiency. Mechanical debubbling is often used to remove these bubbles, using the movement of a breaker bar to break the bubbles. However, it is important to note that for solvents that generate foam during stirring, the bubbles must not come into contact with the solvent during the debubbling process, as this will create new bubbles while removing the bubbles.

[0003] However, during the surfactant production process, the liquid level of the solvent often changes. In order to ensure that the defoaming device does not contact the liquid surface and cause agitation, and to ensure that the defoaming device corresponds to the position of the bubbles, manual operation is often required. The height of the defoaming device is adjusted according to the liquid level before defoaming, which is time-consuming and labor-intensive. It is inconvenient to automatically adjust the position of the defoaming device according to changes in the liquid level, so there are limitations. Utility Model Content

[0004] The technical problem to be solved by the utility model is that the existing debubbling device is inconvenient to automatically adjust the position of the debubbling device according to the height of the solvent liquid level to ensure that the debubbling device does not contact the liquid surface and cause agitation to generate new bubbles.

[0006] As an improvement, there is a gap between the lower end of the rotating shaft and the liquid surface in the storage box.

[0007] As an improvement, the inner wall of the liquid level monitoring tank is provided with liquid inlet holes evenly distributed up and down, and the liquid inlet holes connect the liquid level monitoring tank with the interior of the storage box.

[0008] As an improvement, an inflatable float is fixedly provided below the displacement sensor.

[0009] As an improvement, an adjustment box is fixedly installed above the support frame, and the lifting motor is located on the adjustment box; the output shaft of the lifting motor is fixedly connected to a screw rod rotatably set in the adjustment box, and a movable plate is threadedly connected to the screw rod.

[0010] As an improvement, a connecting rod fixedly connected to the lifting plate is fixedly connected to the bottom of the movable plate, and the connecting rod is slidably arranged relative to the adjustment box and the support frame.

[0011] Beneficial effects of the utility model:

[0012] A debubbling motor is installed at the bottom of the lifting plate.

[0018] The present invention will be further described below with reference to the accompanying drawings.

[0019] according to Figure 1-4 As shown: The utility model provides a defoaming device for surfactant production: it includes a storage box 1, in which the surfactant production solvent is stored; the upper part of the storage box 1 is connected to a liquid inlet pipe 2, and the lower part of the storage box 1 is connected to a liquid outlet pipe 6; a support frame 3 is fixedly provided on the storage box 1, and a lifting plate 8 is provided below the support frame 3 to slide up and down; a defoaming motor 9 is provided at the bottom of the lifting plate 8, and a rotating shaft 11 is fixedly connected to the output shaft of the defoaming motor 9, and a breaking rod 10 is fixedly provided on the rotating shaft 11; a liquid level monitoring groove 15 connected to the storage box 1 is opened on the inner wall of the storage box 1, and a displacement sensor 18 is provided in the liquid level monitoring groove 15, and a controller 5 connected to the displacement sensor 18 circuit is provided on the support frame 3; a lifting motor 13 capable of controlling the lifting plate 8 to slide up and down is provided above the support frame 3, and the lifting motor 13 is connected to the controller 5 circuit.

[0020] By providing a displacement sensor 18 to automatically monitor the liquid level, and using the controller 5 to control the operation of the lifting motor 13 to drive the lifting plate 8 to move synchronously, it is possible to ensure that the debubbling device is always located on the liquid surface, thereby ensuring the debubbling effect. The position of the debubbling device can be automatically adjusted in real time without manual operation, saving manpower.

[0021] There is a gap between the lower end of the rotating shaft 11 and the liquid surface in the storage box 1 to ensure that the rotating shaft 11 and the breaking rod 10 do not contact the liquid surface to cause agitation, thereby avoiding the generation of new bubbles.

[0022] Liquid inlet holes 16 are evenly distributed vertically on the inner wall of the liquid level monitoring tank 15, and the liquid inlet holes 16 connect the liquid level monitoring tank 15 with the interior of the storage box 1. An inflatable float 17 is fixedly provided below the displacement sensor 18.

[0023] The liquid inlet 16 can ensure that the liquid level monitoring tank 15 is consistent with the liquid level inside the storage tank, and the inflatable float 17 can float on the liquid surface, thereby driving the displacement sensor 18 to change according to the change of the liquid level.

[0024] An adjustment box 4 is fixedly mounted above the support frame 3, and a lifting motor 13 is located on the adjustment box 4. A screw 14, which is rotatably mounted within the adjustment box 4, is fixedly connected to the output shaft of the lifting motor 13. A movable plate 12 is threadedly connected to the screw 14. A connecting rod 7, which is fixedly connected to the lifting plate 8, is fixedly mounted below the movable plate 12. The connecting rod 7 slides relative to the adjustment box 4 and the support frame 3.

[0025] The setting of the connecting rod 7 can limit the rotation of the movable plate 12 , thereby converting the rotation of the screw rod 14 into the movement of the movable plate 12 , and transmitting the movement to the lifting plate 8 through the connecting rod 7 .

[0026] Principle of the utility model

[0027] like Figure 2 、 4 As shown, the solution in the storage tank 1 can enter the liquid level monitoring tank 15 through the liquid inlet 16, so the liquid level height in the liquid level monitoring tank 15 can be kept consistent with the liquid level height in the storage tank 1. When the liquid level height changes, the inflatable float 17 in the liquid level monitoring tank 15 can drive the position of the displacement sensor 18 to change. The controller 5 can monitor the position of the displacement sensor 18 in real time and start the lifting motor 13 according to the monitoring result. Figure 3 As shown, driven by the movable plate 12 and the connecting rod 7, the lifting plate 8 can move up and down to ensure that the position of the defoaming motor 9 and its connecting structure can be consistent with the change of the liquid level, thereby ensuring that the defoaming device is always located on the surface of the liquid for defoaming, so as to ensure a good defoaming effect.
