Description

Technical Field

[0001] This utility model belongs to the technical field of material dissolution and mixing equipment, and in particular relates to an automatic aeration device for material dissolution. Background Technology

[0002] In industrial production, the dissolution efficiency of materials directly affects production efficiency and product quality. Traditional dissolution methods typically rely on mechanical stirring or heating, but these methods suffer from low efficiency and high energy consumption when processing complex or solid materials. In recent years, aeration and stirring technology, which uses gas injection to induce stirring, has improved efficiency and achieved significant energy savings, gradually becoming an important means of improving dissolution efficiency.

[0003] However, traditional aeration mixing methods suffer from the problem of material dispersion throughout the entire chamber, resulting in a small aeration contact area and low aeration efficiency. For example, prior art CN211800486U discloses an aeration port at the bottom of the mixing chamber with an air pump connected to it via an air supply pipe, but the aeration device is horizontally positioned at the bottom, leading to low aeration efficiency. Prior art CN217016125U discloses a vertical aeration pipe, but this also suffers from uneven aeration and low aeration efficiency.

[0004] Meanwhile, existing aeration and mixing technologies mostly rely on manual or timed control. Manual operation depends on experience for aeration time, which is highly subjective and lacks timeliness, resulting in energy waste. Timed control uses a fixed-time controller to automatically open and close the aeration valve. This control method cannot adjust the aeration process according to the amount of material. When the amount of material is too small, it is easy to over-aerate, which leads to increased energy consumption. When the amount of material is too large, it will lead to insufficient dissolution. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides an automatic aeration device for material dissolution. By optimizing the structure of the housing and aeration pipes, and dynamically adjusting the aeration rate and circulation pump power, the material dissolution efficiency can be improved and energy consumption reduced.

[0006] The technical solution of this utility model is implemented as follows: In a first aspect, this utility model provides an automatic aeration device for dissolving materials. The automatic aeration device includes a housing, an aeration assembly, a sensor, and a controller. The housing includes an outer housing and an inner housing, with the inner housing located inside the outer housing and a water outlet hole provided on the side wall of the inner housing. The aeration assembly includes a vertical aeration pipe that extends into the inner housing and has multiple aeration branch pipes arranged from top to bottom. The multiple aeration branch pipes are staggered on the vertical aeration pipe, and the inner diameter of the aeration branch pipes gradually increases from top to bottom. Each aeration branch pipe has multiple aeration holes.

[0007] The staggered distribution design of the aeration branch pipes helps to release gas evenly, avoids excessive or insufficient gas in some areas, and improves aeration uniformity. The inner diameter of multiple aeration branch pipes is set to gradually increase from top to bottom, which can prevent the phenomenon of insufficient gas volume at the bottom from making it difficult to aerate, thus ensuring uniform aeration from top to bottom. The multiple aeration holes on the aeration branch pipes can increase the contact area between gas and material, thereby improving aeration efficiency.

[0008] Furthermore, each of the aeration branch pipes has aeration holes evenly distributed in the circumferential direction.

[0009] Furthermore, the aeration branch pipes are inclined on the vertical aeration pipes, and adjacent aeration branch pipes on the same side are inclined in opposite directions, which makes the aeration range larger and avoids dead corners where materials accumulate.

[0010] The upper end of the vertical aeration pipe is connected to an air source via an air inlet pipe, which is equipped with a proportional valve. The proportional valve is connected to the controller via a signal connection.

[0011] Furthermore, the bottom of the vertical aeration pipe is also provided with a drain hole to facilitate the drainage of liquid inside the pipe and prevent liquid residue from remaining inside the vertical aeration pipe.

[0012] Furthermore, the number of vertical aeration pipes is at least two, and the vertical aeration pipes are evenly distributed in the inner box, so that the material in different positions in the inner box can fully contact the airflow and improve the material dissolution efficiency.

[0013] Furthermore, the length of each vertical aeration pipe may be the same or different.

[0014] Furthermore, each vertical aeration pipe is equipped with a proportional valve on its air inlet pipe, and each proportional valve is connected to the controller signal and can independently adjust its opening.

[0015] Furthermore, the sensor includes a liquid level sensor and a conductivity sensor.

[0016] Furthermore, the liquid level sensor is an ultrasonic liquid level sensor; the ultrasonic liquid level sensor is located above the outer casing and is used to detect the liquid level height in the casing.

[0017] This new design uses a double-layered housing consisting of an outer and an inner chamber. The material to be dissolved is added to the inner chamber for dissolution, resulting in a relatively concentrated material distribution. This increases the contact area between the material and the aeration components, thereby improving the aeration and dissolution efficiency. Furthermore, since the material is added to the inner chamber and aeration takes place within it, the liquid surface in the outer chamber remains relatively calm and free from solid particle interference, ensuring the accuracy of the ultrasonic level sensor measurement.

[0018] Furthermore, the conductivity sensor is located on the side wall of the outer casing and is used to detect the conductivity of the material in the casing. The controller determines whether the material is saturated based on the conductivity value.

[0019] The material is an inorganic salt solid, such as sodium chloride, sodium sulfate, calcium chloride, sodium hydroxide, sodium bicarbonate, ammonium nitrate, etc.

[0020] The controller is connected to the liquid level sensor and the conductivity sensor. The controller adjusts the opening of the proportional valve according to the liquid level height detected by the liquid level sensor and the solution conductivity detected by the conductivity sensor, thereby controlling the aeration volume and aeration time.

[0021] Furthermore, the automatic aeration device also includes a circulation component, which includes a circulation pipe and a circulation pump. The inlet of the circulation pipe is connected to the bottom of the outer casing, and the outlet of the circulation pipe is connected to the top of the inner casing. The circulation pump is signal-connected to the controller.

[0022] This novel design connects a controller to a liquid level sensor and a conductivity sensor. The liquid level signal detected by the liquid level sensor and the solution conductivity signal detected by the conductivity sensor are both transmitted to the controller. Simultaneously, the controller connects to a proportional valve and a circulating pump to adjust the opening degree of the proportional valve and the frequency of the circulating pump. The liquid level signal controls the start of the proportional valve and circulating pump, thus initiating operation. The solution conductivity signal dynamically adjusts the opening degree of the proportional valve and the frequency of the circulating pump. When the conductivity is low, the proportional valve is 100% open, and the circulating pump operates at high frequency. As the conductivity increases, the opening degree of the proportional valve decreases, and the frequency of the circulating pump decreases. When the conductivity reaches a predetermined value, the proportional valve and circulating pump are closed, stopping aeration and circulation. This achieves fully automated management of the material production process, thereby saving manpower, reducing energy consumption, and lowering costs.

[0023] Compared with existing technologies, the automatic aeration device of this utility model has the following advantages: This invention features a double-layered housing consisting of an outer and an inner chamber. The material to be dissolved is added to the inner chamber for dissolution, resulting in a relatively concentrated material distribution. This increases the contact area between the material and the aeration components, thereby improving the aeration and dissolution efficiency. Furthermore, since the material is added to the inner chamber and aeration takes place within it, the liquid surface in the outer chamber remains relatively calm and free from solid particle interference, ensuring the accuracy of the ultrasonic level sensor measurement.

[0024] The staggered distribution design of the aeration branch pipes in this invention helps to release gas evenly, avoids excessive or insufficient gas in certain areas, and improves aeration uniformity. The inner diameter of the multiple aeration branch pipes is set to gradually increase from top to bottom, which can prevent the phenomenon of insufficient gas volume at the bottom from making it difficult to aerate, thus ensuring uniform aeration from top to bottom. The multiple aeration branch pipes are inclined on the vertical aeration pipe, and the adjacent aeration branch pipes on the same side are inclined in opposite directions, which makes the aeration range larger and avoids dead corners where materials accumulate. The multiple aeration holes on the aeration branch pipes can increase the contact area between gas and materials and improve aeration efficiency.

[0025] This invention uses the liquid level signal detected by the liquid level sensor to control the proportional valve and the circulation pump to start operation; it uses the solution conductivity signal detected by the conductivity sensor to control the opening degree of the proportional valve and the frequency of the circulation pump; it realizes the full-process automated management of material production, which can save manpower, reduce energy consumption and reduce costs.

[0029] It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0030] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0031] Example 1 like Figure 1As shown, this embodiment provides an automatic aeration device for dissolving materials, specifically sodium chloride. The automatic aeration device includes a housing, an aeration assembly, a sensor, and a controller. The housing includes an outer housing 1 and an inner housing 2, with the inner housing 2 located inside the outer housing 1 and having a water outlet hole on its side wall. The aeration assembly includes a vertical aeration pipe 3 extending into the inner housing 2, and multiple aeration branch pipes 4 arranged from top to bottom. The multiple aeration branch pipes 4 are staggered on the vertical aeration pipe 3, with the inner diameter of each aeration branch pipe 4 gradually increasing from top to bottom. Each aeration branch pipe 4 has aeration holes 5 evenly distributed in the circumferential direction.

[0032] The aeration branch pipe 4 is inclined on the vertical aeration pipe 3, and the adjacent aeration branch pipes 3 on the same side are inclined in opposite directions, so that the aeration range is larger and the dead corners of material accumulation are avoided.

[0033] The bottom of the vertical aeration pipe 3 is also provided with a drain hole to facilitate the drainage of liquid in the pipe and prevent liquid residue from remaining in the vertical aeration pipe 3.

[0034] There are two vertical aeration pipes 3 of different lengths, which are evenly distributed in the inner box 2, so that the material in different positions of the inner box 2 can be fully dispersed, thereby improving the material dissolution efficiency.

[0035] The aeration branch pipes 4 on each vertical aeration pipe 3 are distributed in different and complementary positions in the vertical direction. That is, the upper part of the long vertical aeration pipe is not equipped with an aeration branch pipe, but only the lower part is equipped with an aeration branch pipe. This can prevent the phenomenon that the lower part is difficult to aerate due to insufficient air volume, and ensure that each height can be fully aerated.

[0036] The upper end of each vertical aeration pipe 3 is connected to an air source through an air inlet pipe. A proportional valve 6 is provided on the air inlet pipe. Each proportional valve 6 is connected to the controller signal and can independently adjust the opening degree.

[0037] The sensors include an ultrasonic level sensor 7 and a conductivity sensor 8. The ultrasonic level sensor is located above the outer casing 1; the conductivity sensor 8 is located on the side wall of the outer casing 1 and is used to detect the conductivity of the sodium chloride solution in the casing.

[0038] The controller is connected to the ultrasonic level sensor 7 and the conductivity sensor 8. The controller adjusts the opening of the proportional valve according to the liquid level height detected by the ultrasonic level sensor 7 and the conductivity of the sodium chloride solution detected by the conductivity sensor 8, thereby controlling the aeration volume and aeration time.

[0039] The automatic aeration device also includes a circulation component, which includes a circulation pipe 9 and a circulation pump 10. The inlet of the circulation pipe 9 is connected to the bottom of the outer casing 1, and the outlet of the circulation pipe 9 is connected to the top of the inner casing 2. The circulation pump 10 is connected to the controller via a signal.

[0040] The operation process of the automatic aeration device in this embodiment is as follows: (1) Fill the box with water to a certain level. The ultrasonic level sensor detects and records this level as L1. Add a fixed amount of sodium chloride solid salt particles into the inner box. When the ultrasonic level sensor detects that the liquid level height is L2 and L2 is greater than L1, without manual startup, the proportional valve is automatically opened and aeration is started. (2) When starting aeration, both proportional valves are fully opened at 100%. The circulation pump operates at the reference frequency F1 to achieve strong aeration and strong circulation. (3) As the conductivity sensor detects that the solution conductivity rises steadily, the controller gradually reduces the opening degree of the proportional valve according to the preset program, and at the same time adjusts the frequency of the circulation pump to F2 (F2 < F1) to reduce energy consumption while ensuring the dissolution effect. (4) When the conductivity value reaches the preset saturation value (≥200 mS / cm), the controller closes the proportional valve and the circulation pump, and the dissolution process ends.

[0041] Test Example 1 Reliability Test Refer to the standard GB / T 2423.17 - 2008 for a 240 - hour continuous salt spray test. After detection, the salt crystal coverage rate on the surface of the ultrasonic level sensor < 0.1%, and the mis - triggering rate of the controller program: 0 / 10,000 times (test standard IEC61131 - 2). It is proved that the automatic aeration device of the present utility model has a low failure rate and can meet the requirements of long - term stable operation.

[0042] The above - described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. Based on the embodiments of the present utility model, other embodiments obtained by those skilled in the art without creative efforts all fall within the scope of protection of the present utility model.
