[0002] Defoaming is to take certain measures to break up the formed foam or reduce the thickness of the foam layer. The premise for recycling foam fluid is that there must be a feasible defoaming method.
[0003] Most of the existing auxiliary methods for eliminating the foam generated by the bacterial strain activation fermentation are to use a stirring rod to rotate at a low speed to break up and eliminate the foam generated during the bacterial strain activation fermentation process.
[0004] Although this method can break up and eliminate the foam generated by the fermentation of the bacteria to a certain extent, the efficiency of breaking up and eliminating the foam by simple stirring is low, and the height of the stirring rod is generally set at a fixed height, so it is also impossible to break up and eliminate the foam generated at different heights of the fermentation liquid.
[0005] Therefore, we made improvements to this problem and proposed a defoaming system for bacterial activation and fermentation. Utility Model Content
[0006] In order to solve the above technical problems, the utility model provides the following technical solutions:

[0010] As a preferred technical solution of the utility model, one end of the threaded rod away from the motor is rotatably connected to a bearing, and the bearing is fixedly connected to the inner bottom surface of the barrel body.
[0011] As a preferred technical solution of the utility model, a limiting rod is fixedly connected to the bottom surface of the barrel body, two groups of limiting rods are symmetrically arranged, the limiting rods are slidably connected to the defoaming plate, and a baffle is fixedly connected to the top of the limiting rod.
[0012] As a preferred technical solution of the utility model, a spring is fixedly connected to the stirring rod, and multiple groups of springs are arranged in the vertical direction of the stirring rod. A scraper is fixedly connected to one end of the spring away from the stirring rod, and the scraper is in sliding contact with the inner wall of the barrel.

[0020] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.
[0021] Example: Figures 1 to 4 As shown, the utility model shows a defoaming system for bacterial strain activation and fermentation, comprising a barrel body 1, to which a barrel cover 2 is detachably connected by bolts, to which a feed port 4 is fixedly connected, a defoaming assembly is arranged inside the barrel body 1, the defoaming assembly comprises a stirring rod 11 which can rotate inside the barrel body 1, the stirring rod 11 rotates in a circle around the center of the barrel body 1, the defoaming assembly also comprises a defoaming plate 8 which can move in a vertical direction inside the barrel body 1, a defoaming roller 13 is arranged inside the defoaming plate 8, a defoaming thorn 131 is fixedly connected to the outer peripheral wall of the defoaming roller 13, and the top of the defoaming thorn 131 is arranged in a conical structure.
[0022] By utilizing the feed port 4 fixedly connected to the barrel cover 2, it is easier to add the foam eliminating agent into the barrel body 1 through the feed port 4. At the same time, the stirring rod 11 that can rotate in a circle around the vertical axis of the barrel body 1 inside the barrel body 1 can break up and eliminate the foam in the bacterial activation fermentation liquid. At the same time, the defoaming roller 13 arranged inside the defoaming plate 8 that can move in the vertical direction of the barrel body 1 and the defoaming thorns 131 fixedly connected to the outer peripheral wall of the defoaming roller 13 can break up and eliminate the foam at different heights in the bacterial activation fermentation liquid, which is more efficient to use.
[0023] The defoaming roller 13 is rotatably arranged inside the defoaming plate 8 via a rotating shaft 14. Two cavities are symmetrically arranged on the defoaming plate 8, and the defoaming roller 13 is symmetrically arranged inside the cavities. By using the defoaming roller 13 and the defoaming thorns 131 symmetrically arranged in the two cavities on the defoaming plate 8, it is more convenient to use the cone at the top of the defoaming thorns 131 to break and eliminate the foam, which is more convenient to use.
[0024] A motor 3 is fixedly connected to the barrel cover 2, and the output shaft of the motor 3 is vertically downward and fixedly connected to the stirring rod 11 through a coupling. A threaded rod 5 is also fixedly connected to the output shaft of the motor 3, and the defoaming plate 8 is threadedly connected to the threaded rod 5. The end of the threaded rod 5 away from the motor 3 is rotatably arranged with the inner bottom surface of the barrel body 1.
[0025] By setting the motor 3 as a slow motor, it is easier to use the motor 3 to drive the stirring rod 11 to rotate slowly. At the same time, the motor 3 can drive the threaded rod 5 to rotate. By using the threaded connection between the threaded rod 5 and the defoaming plate 8, it is easier to drive the defoaming plate 8 to move in the vertical direction inside the barrel body 1.
[0026] The end of the threaded rod 5 away from the motor 3 is rotatably connected to a bearing 6, and the bearing 6 is fixedly connected to the inner bottom surface of the barrel body 1. By using the bearing 6 rotatably connected to the end of the threaded rod 5 away from the motor 3 and the bearing 6 being fixedly connected to the inner bottom surface of the barrel body 1, it is more convenient to use the motor 3 to drive the threaded rod 5 to rotate.

The limit rods 7 are slidably connected to the defoaming plate 8, and a baffle 10 is fixedly connected to the top of the limit rod 7. By using the limit rod 7 fixedly connected to the inner bottom surface of the barrel body 1 and the sliding connection between the limit rod 7 and the defoaming plate 8, it can be ensured that the defoaming plate 8 always moves in the vertical direction of the barrel body 1 when the threaded rod 5 rotates.
[0028] A spring 12 is fixedly connected to the stirring rod 11 . Multiple groups of springs 12 are arranged in the vertical direction of the stirring rod 11 . A scraper 9 is fixedly connected to one end of the spring 12 away from the stirring rod 11 . The scraper 9 is in sliding contact with the inner wall of the barrel 1 .
[0029] By utilizing the spring 12 fixedly connected to the stirring rod 11 and the fixed connection between the spring 12 and the scraper 9, the scraper 9 can be utilized to clean and scrape the inner wall of the barrel body 1 when the stirring rod 11 rotates in a circle, which is more conducive to cleaning the inner wall of the barrel body 1 and is more convenient to use.
[0030] During operation, when it is necessary to defoam the foam generated during the activation and fermentation of the bacteria, the defoaming agent is put into the barrel body 1 through the feed port 4, and then the motor 3 is started (slow speed) to rotate slowly, and the motor 3 is used to drive the stirring rod 11 to stir the activated fermentation liquid of the bacteria, and then the threaded connection between the rotating threaded rod 5 and the defoaming plate 8 is used to drive the defoaming plate 8 to move in the vertical direction, and the conical defoaming thorns 131 fixedly connected to the rotatable defoaming roller 13 provided in the defoaming plate 8 are used to puncture and disperse the foam.
[0031] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model.
