Description

Technical Field

[0001] This utility model relates to the field of fermentation tank technology, specifically, to a fermentation tank bubble elimination device that is easy to adjust. Background Technology

[0002] A fermenter is a container used in biological fermentation processes and is widely used in the food, beverage, pharmaceutical, and chemical industries. Its main function is to provide an environment suitable for the growth and metabolism of microorganisms. By controlling parameters such as temperature, humidity, pH, and dissolved oxygen, it promotes the transformation of raw materials by microorganisms to produce target products such as yeast, yogurt, beer, and pharmaceuticals.

[0003] Defoamers are chemical substances used to eliminate or inhibit the formation of foam in liquids. They typically work by altering the surface tension of the liquid, causing the foam to break down or reducing its formation. Defoamers generally consist of surfactants, synergists, solvents, and other auxiliary ingredients.

[0004] Because bubbles are generated inside the fermenter during operation, defoamers can be added to dissolve them. Chinese utility model patent CN219849393U provides a defoamer adding device, which improves the range of defoamer addition and thus enhances uniformity. However, the amount of defoamer added varies depending on the bubble pattern, resulting in inconsistent volumes of defoamer added each time. This necessitates adjustments to the volume of water used for dilution to maintain a relatively stable dilution ratio. However, this is difficult to control manually. Furthermore, adding a sufficient amount of defoamer at once lacks accuracy and may lead to over-addition. Ideally, the amount of defoamer added should be adjusted in real-time to ensure timely foam dissolution while avoiding negative impacts from excessive addition on the fermentation process. Utility Model Content

[0005] The purpose of this invention is to provide a fermentation tank bubble defoaming device that is easy to adjust, and to solve the problems of difficulty in controlling the dilution ratio and easy over-addition of defoamer in existing defoamer addition.

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 protection scope of the present utility model.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Example 1:

[0028] This embodiment provides an easily adjustable fermenter bubble elimination device, specifically as follows: Figures 1-3 As shown, including;

[0029] A dispensing container for loading and dispensing defoamer includes a storage tank 101, an inlet pipe 103, a servo motor 105, and a dispensing disc 106. The storage tank 101 has inlet and outlet ports and is supported by a bracket 102. The inlet pipe 103 and the servo motor 105 are both mounted on the storage tank 101. The dispensing disc 106 is drivenly connected to the servo motor 105 and rotatably connected to the storage tank 101. The dispensing disc 106 has multiple dispensing chambers 110. A sealing cover 107 is installed on the inlet pipe 103. A spray disc 108 is installed on the sealing cover 107 and has multiple spray holes 111. The spray disc 108 is aligned with the outlet axis of the storage tank 101. The sealing cover 107 is in close contact with the end face of the dispensing disc 106.

[0030] The agent delivery pipe is connected to the outlet of the storage tank 101 and is used to transport the agent into the fermentation tank to dissolve the bubbles.

[0031] During use, connect the inlet pipe 103 to a high-pressure water pipe, and then add the defoamer through the inlet of the storage tank 101. The defoamer fills the metering chamber 110. Initially, the end face of the spray plate 108 is blocked by the metering plate 106, meaning the high-pressure water is blocked. Start the servo motor 105, which drives the metering plate 106 to rotate. As the metering plate 106 rotates, one metering chamber 110 begins to approach the sealing cover 107 and slowly moves below it. At this point, the upper end of the metering chamber 110 is blocked by the sealing cover 107, and the lower end is blocked by the storage tank 101. The amount of defoamer it contains remains unchanged until the metering chamber 110 rotates... When the metering chamber 110 moves to coincide with the outlet of the storage tank 101, the lower end face of the metering chamber 110 is no longer blocked by the storage tank 101, while the upper end face is in contact with the spray plate 108. At this time, high-pressure water is sprayed into the metering chamber 110 through the spray hole 111. Then, the clean water and defoaming emulsion are mixed and flow into the drug delivery pipe, and the clean water ends up completely rinsing the defoamer to prevent it from remaining in the drug delivery pipe. Finally, it flows into the fermentation tank. After that, the servo motor 105 continues to rotate, so that the metering plate 106 continues to block the spray plate 108. At this time, the clean water cannot flow in, and the metering chamber 110 no longer coincides with the spray plate 108, that is, the drug delivery stops.

[0032] Based on the above working principle, the dosage of medicine stored in a metering chamber 110 is counted as one unit; the conduction time between the spray plate 108 and the metering chamber 110 is controlled to control the amount of high-pressure water flowing in; one unit of medicine is mixed with water and diluted before being put into the fermentation tank, and after waiting for a few seconds to a few minutes, the dissipation of bubbles is observed. If the dissipation of bubbles is small, the servo motor 105 is driven to add another unit of medicine; until the dissipation of bubbles meets the standard.

[0033] The reagent is metered through the metering chamber 110, and the water volume is controlled by controlling the rotation and dwell time of the servo motor 105. This ensures that the dilution ratio is relatively fixed, preventing insufficient dilution due to too little water and also preventing excessive water from altering the fermenter environment. Adding the reagent in small amounts multiple times makes it easy to adjust the amount of reagent added, while continuously observing the bubble dissipation rate. This also prevents adding too much reagent at once from affecting the fermenter environment.

[0034] Example 2:

[0035] This embodiment further extends the above embodiment, specifically as follows: Figures 2-4 As shown, the spray hole 111 is inclined at an angle of 30°-50°. The inclined arrangement of the spray hole 111 allows water in the water inlet pipe 103 to pass through the spray hole 111 and then flush against the side wall of the metering chamber 110, thus fully flushing the medicine.

[0036] Preferably, the metering disc 106 is provided with a plurality of sealing rings 109, which are disposed around the metering cavity 110. The sealing rings 109 are provided to improve the sealing performance and ensure that water and medicine do not leak.

[0037] Preferably, the storage tank 101 is equipped with a level gauge 104. The level gauge 104 allows personnel to easily observe the amount of medicine stored in the storage tank 101 from the outside, so that it can be added in a timely manner.

[0038] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0039] Example 3:

[0040] This embodiment further expands upon the above embodiment by modifying the drug delivery tube, specifically as follows: Figures 5-6 As shown, the agent delivery pipe includes a delivery pipe 201, and a reducing pipe 204 is installed at the tail end of the delivery pipe 201. An atomizing nozzle 202 is installed on the reducing pipe 204. The bracket 102 is installed on the top of the fermenter, and the reducing pipe 204 is connected to a flange with a pre-drilled hole on the top of the fermenter.

[0041] When the high-pressure water at the inlet pipe 103 carries the medicine into the delivery pipe 201, the diluted medicine will flow along the delivery pipe 201 to the atomizing nozzle 202, and under pressure, it will be sprayed out in a diffused manner, evenly sprayed into the fermenter.

[0042] Furthermore, a flow-damping element is installed on the delivery pipe 201. The flow-damping element includes a delivery shaft 203, mounting rings 205, and a spiral blade 206. A mounting ring 205 is installed at each end of the delivery shaft 203, and the mounting rings 205 are embedded in the flanges at both ends of the delivery pipe 201. The spiral blade 206 is mounted on the delivery shaft 203. When the diluted medicine flows on the spiral blade 206, its flow rate is slowed down, reducing the noise generated by the water flow impacting the pipe wall of the delivery pipe 201, thus achieving a noise reduction effect.

[0043] Furthermore, a plurality of blocking units are installed on the spiral blade 206. The blocking unit includes a first blocking strip 207 and a second blocking strip 208. The first blocking strip 207 and the second blocking strip 208 are both fixed on the spiral blade 206. The guiding direction of the water flow by the first blocking strip 207 is opposite to that of the second blocking strip 208.

[0044] As the water flows on the spiral blade 206, it alternately passes through the first baffle 207 and the second baffle 208. Part of the water impacts the first baffle 207, while some flows directly to the second baffle 208. Of the water impacting the first baffle 207, some is guided by it to the second baffle 208, while the rest flows over it. The portion flowing directly to the second baffle 208 and the portion guided by the first baffle 207 to the second baffle 208 impact and converge there, mixing. Then, the water guided by the second baffle 208 flows to the next first baffle 207, where the portion that flowed over the first baffle 207 impacts and converges with the portion guided by the second baffle 208, mixing again. By continuously changing the flow rate and direction of the defoamer, it continuously converges and separates, thus achieving mixing without the need for an external stirring device.

[0045] The other parts of this embodiment are the same as those in the above embodiments, and will not be described again.

[0046] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the present utility model.
