DETAILED DESCRIPTION

[0019] The utility model is described in detail below with reference to the accompanying drawings and specific implementation modes.

[0020] Example 1

[0021] The utility model discloses a defoaming device for adding medicine for defoaming experiment of gas well, comprising a mixing tank 1, wherein a feeding pipe 15 and a discharging pipe 16 are respectively arranged at the top and the lower side of the mixing tank 1, and the discharging pipe 16 is used for injecting and discharging water and defoaming agent, a driving device is fixed at the top of the mixing tank 1, a horizontally arranged horizontal plate 2 is arranged at the top of the mixing tank 1, an output end of the driving device passes through the top of the mixing tank 1 and vertically extends into the inside of the mixing tank 1 and is fixedly connected with a rotating shaft 4, and the other end of the rotating shaft 4 passes through the horizontal plate 2 and is fixedly connected with a second gear 9, and the horizontal plate 2 is rotatably connected with the rotating shaft 4, that is, the rotating shaft 4 directly passes through the horizontal plate 2 and can rotate in the horizontal plate 2, and the horizontal plate 2 is equivalent to being sleeved on the rotating shaft 4, the horizontal plate 2 is symmetrically provided with chute 5 on both sides of the rotating shaft 4, a slider 6 is slidably connected in the chute 5, and a stirring shaft 7 is rotatably connected at the bottom of the slider 6, and a second gear 9 is meshed with a first gear 8 at the position corresponding to the two stirring shafts 7, and the two first gears 8 are fixedly sleeved on the stirring shaft 7, and the lower end of the stirring shaft 7 passes through the first gear 8 and extends into the lower part of the mixing tank 1, the second gear 9 is set as an elliptical gear, and the first gear 8 is a circular gear. When the second gear 9 and the two first gears 8 are meshed and transmitted, the two sliders 6 are driven to slide in the corresponding chute 5, and a plurality of stirring blades are evenly arranged at the position of the stirring shaft 7 below the first gear 8.

[0022] The working principle of the defoaming device for gas well defoaming experiment in this embodiment is as follows:

[0023] After water and defoaming agent are injected into the mixing tank 1, the motor 3 is started to drive the rotating shaft 4 to rotate, and the rotating shaft 4 drives the stirring shaft 7 to rotate through the first gear 8 and the second gear 9, so that the stirring shaft 7 stirs and mixes the water and defoaming agent in the mixing tank 1;

[0024] At the same time, since the second gear 9 is an elliptical structure, when the second gear 9 is meshing with the first gear, the second gear 9 and the two first gears 8 are meshing and transmitting, driving the two sliders 6 to slide in the corresponding slide grooves 5, and the sliders 6 then drive the stirring shaft 7 to move back and forth, so that the stirring shaft 7 itself stirs the water and the defoaming agent back and forth while rotating, thereby improving the stirring effect and allowing the water and the defoaming agent to be evenly mixed.

[0025] Example 2

[0026] On the basis of Example 1, a rotating plate 11 is fixedly sleeved on the rotating shaft 4 above the horizontal plate 2, and an annular groove 12 is provided on the lower surface of the rotating plate 11. A slide bar 13 is fixed on the top of the two sliders 6. The rotating plate 11 has the same shape as the second gear 9, and the two slide bars 13 slide in the groove 12 when the rotating shaft 4 drives the rotating plate 11 to rotate. The motor 3 drives the rotating plate 11 to rotate through the rotating shaft 4, and the rotating plate 11 squeezes the slide bar 13 through the inner wall of the groove 12, thereby driving the slider 6 to slide back and forth in the slide groove 5; the slider 6 then drives the stirring shaft 7 to move back and forth, so that the stirring shaft 7 itself stirs the water and the defoaming agent back and forth while rotating, thereby improving the stirring effect and allowing the water and the defoaming agent to be mixed evenly.

[0027] The second gear 9 and the rotating plate 11 are both elliptical structures. The second gear 9 is always meshed with the first gear 8. When the second gear 9 rotates, it can drive the stirring shaft 7 to rotate through the first gear 8. Since the second gear 9 is an elliptical structure, the first gear 8 does not rotate at a constant speed all the time, but rotates at a variable speed from time to time, which can improve the stirring effect. The rotating plate 11 with an elliptical structure cooperates with the second gear 9, and drives the slider 6 and the stirring shaft 7 to move back and forth through the groove 12 and the slide rod 13.

[0028] Example 3

[0029] On the basis of Example 2, the driving device is a motor 3, which is fixed on the top of the mixing tank 1. The output shaft of the motor 3 vertically penetrates the top wall of the mixing tank 1 and extends to the inside of the mixing tank 1. The output shaft of the motor 3 is rotatably connected to the top wall of the mixing tank 1, and the output shaft of the motor 3 is fixedly connected to the rotating shaft 4. A control switch 14 is fixedly connected to the outside of the mixing tank 1. The motor 3 is electrically connected to the control switch 14 through a cable. The electrical equipment in the device is powered by an external power supply such as a mains power supply, and the start and stop of the motor 3 is controlled by the control switch 14.

[0030] Example 4

[0031] On the basis of Example 1 or 2, a spring 10 is fixedly connected to one side of the slider 6 close to the rotating shaft 4, and the other end of the spring 10 is fixedly connected to the inner wall of the corresponding slide groove 5 close to the rotating shaft 4. The tension of the spring 10 provides a tendency for the slider 6 to move toward the direction close to the rotating shaft 4, which is conducive to the movement of the slider 6 toward the direction close to the rotating shaft 4.

[0032] The cross section of the slider 6 is an I-shaped structure, and the upper and lower inner walls of the I-shaped slider 6 are respectively fitted with the upper and lower outer surfaces of the cross plate 2. The slider 6 with the I-shaped structure mainly limits itself to prevent the slider 6 from detaching from the cross plate 2.

[0033] An observation window 17 is provided on the side of the mixing tank 1, which is convenient for observing the situation inside the mixing tank 1. When the utility model is used, after water and defoaming agent are injected into the mixing tank 1, the motor 3 is started to drive the rotating shaft 4 to rotate, and the rotating shaft 4 drives the stirring shaft 7 to rotate through the first gear 8 and the second gear 9, and the water and the defoaming agent are stirred and mixed by the stirring shaft 7. At the same time, the rotating shaft 4 drives the rotating plate 11 to rotate, and the rotating plate 11 drives the slider 6 to move back and forth in the slide groove 5 of the horizontal plate 2 through the groove 12 and the slide rod 13, and the slider 6 then drives the stirring shaft 7 to move back and forth, so that the stirring shaft 7 itself stirs the water and the defoaming agent back and forth while rotating, thereby improving the stirring effect and making the water and the defoaming agent evenly mixed.

For example, it can be a fixed connection, a detachable connection, or an integrated connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the utility model according to the specific circumstances.
