Description

Technical Field

[0001] This utility model relates to the field of defoamer technology, specifically to a defoamer dosing device. Background Technology

[0002] Surface foam is a common problem in chemical treatment processes. The viscosity of foam causes a large amount of solids to float on the surface of the water, reducing the oxygenation efficiency of the chemical tank. Foam accumulation can also lead to putrefaction. Currently, defoaming agents are added to eliminate foam in the chemical tank.

[0003] Currently, when adding defoamers to chemical tanks, the defoamers are directly added into the tank, limiting the area to which they can be applied. This results in insufficient coverage of the tank, requiring the defoamer to spend a considerable amount of time spreading to other areas to eliminate foam, leading to low efficiency in foam elimination. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a defoamer dosing device that solves the problem that defoamer can only be added to a fixed location within the chemical tank, resulting in a limited area for defoamer dosing and insufficient coverage of the chemical tank. Consequently, the defoamer needs to spend a considerable amount of time diffusing to other areas to eliminate foam.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a defoamer dosing device, comprising a dosing mechanism located above a treatment tank, the dosing mechanism including a fixed frame fixedly connected to the top of the treatment tank, a rotating frame below the fixed frame, a rotating tube fixedly connected to the top of the rotating frame through an opening, one end of the rotating tube penetrating the fixed frame and extending above it, a rotating port adapted to the rotating tube being opened at the top of the fixed frame, a rotating mechanism adapted to the rotating tube being provided on one side of the top of the fixed frame, the other end of the rotating tube being connected to a rubber hose, rotating tubes being rotatably connected to both sides of the front and rear of the inner cavity of the rotating frame via bearings, an extension mechanism adapted to the rotating tube being provided at the rear of the inner cavity of the rotating frame, one end of the rubber hose being connected to the rotating tube, a connecting pipe being connected to the surface of the rotating tube, one end of the connecting pipe being connected to a spray pipe, and a plurality of nozzles being connected to the surface of the spray pipe.

[0006] Preferably, the rotating mechanism includes a motor, which is fixedly connected to the top of the mounting frame via a mounting bracket. The output shaft of the motor is fixedly connected to a rotating rod via a coupling. One end of the rotating rod is rotatably connected to the top of the mounting frame via a bearing. The surfaces of the rotating rod and the rotating tube are both fixedly connected to a first gear, and the two first gears mesh with each other.

[0007] Preferably, the extension mechanism includes an electric telescopic rod, the top of the rotating frame is fixedly connected to the electric telescopic rod through an opening, the telescopic end of the electric telescopic rod is fixedly connected to a toothed plate, and a second gear adapted to the toothed plate is fixedly connected to the rear of the surface of the rotating tube.

[0008] Preferably, the top of the rotating frame is provided with an annular groove.

[0009] Preferably, sliding plates are fixedly connected to both sides of the top of the inner cavity of the fixed frame, and the bottom of the sliding plates is slidably connected to the annular groove through a slider.

[0010] Preferably, the end of the rotating tube is connected to a liquid addition tube via a rotary joint.

[0011] Beneficial effects:

[0012] This invention provides a defoamer dosing device. Compared with existing technologies, it has the following advantages:

[0013] (1) This utility model controls the electric telescopic rod to extend and retract, which drives the toothed plate to move up and down. The toothed plate drives the rotating tube to rotate in and out through the second gear. The rotating tube drives the spray pipe to rotate and tilt through the connecting pipe, so that the two spray pipes swing back and forth. At the same time, the motor drives the rotating rod to rotate. The rotating rod drives the rotating tube to rotate through the first gear. The rotating tube drives the two swinging spray pipes to rotate through the rotating frame, so that the multiple nozzles on the two spray pipes rotate and spray defoamer. This can greatly increase the spray range of defoamer and improve the efficiency of foam elimination.

[0014] (2) This utility model controls the electric telescopic rod to retract and drive the toothed plate to move upward. The toothed plate will drive the rotating tube to move inward through the second gear, so that the rotating tube drives the two spray pipes to move inward through the connecting pipe, and rotates the two spray pipes to the vertical state and resets them. This can effectively reduce the space occupied by the dosing mechanism and will not affect the normal use of the treatment tank. Attached Figure Description
