Description

Technical Field

[0001] This utility model relates to the field of production control technology, and in particular to a batching device. Background Technology

[0002] In related technologies, the batching device includes a reaction vessel and a storage vessel, with the storage vessel connected to the reaction vessel via a pipeline. The desired target product is obtained by introducing liquid from the storage vessel into the reaction vessel to carry out the reaction.

[0003] Reaction vessels often require a set mass or volume of liquid to be introduced. To achieve rapid liquid transfer between vessels, the pipelines connecting the vessels typically have a high flow rate. During batching, once the liquid mass or volume in the reaction vessel reaches or approaches the set value, the valve is closed manually or electrically to shut off the pipeline connecting the reaction vessel and the storage vessel. However, due to the high instantaneous flow rate in the pipelines, the actual value in the reaction vessel often deviates significantly from the set value. Utility Model Content

In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Furthermore, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0045] In related technologies, the batching device includes a reaction vessel and a storage vessel, with the storage vessel connected to the reaction vessel via a pipeline. The desired target product is obtained by introducing liquid from the storage vessel into the reaction vessel to carry out the reaction.

[0046] Reaction vessels often require a set mass or volume of liquid to be introduced. To achieve rapid liquid transfer between vessels, the pipelines connecting the vessels typically have a high flow rate. During batching, once the liquid mass or volume in the reaction vessel reaches or approaches the set value, the valve is closed manually or electrically to shut off the pipeline connecting the reaction vessel and the storage vessel. However, due to the high instantaneous flow rate in the pipelines, the actual value in the reaction vessel often deviates significantly from the set value.

[0047] This application discloses a dispensing device. It should be noted that this dispensing device can be applied to the preparation of glass coating solutions, as well as to the preparation of other chemical reagents. For example... Figures 1 to 4As shown, the batching device includes a storage container 100, a transfer container 200, a reaction vessel 300, and a piping assembly 400. The transfer container 200 is connected to both the storage container 100 and the reaction vessel 300 via the piping assembly 400, allowing liquid from the storage container 100 to first flow into the transfer container 200, and then into the reaction vessel 300. The storage container 100 stores the raw materials to be reacted. The transfer container 200 temporarily stores the liquid flowing from the storage container 100 until the incoming liquid reaches a set mass or volume to complete the batching of the raw materials, which is then transported to the reaction vessel 300 for the preparation of the coating solution.

[0048] The piping assembly 400 described above includes a first pipe 410, a second pipe 420, and a third pipe 430. The first pipe 410 connects the storage container 100 and the transfer container 200. The second pipe 420 also connects the storage container 100 and the transfer container 200. The third pipe 430 connects the transfer container 200 and the reaction vessel 300, with liquid in the transfer container 200 entering the reaction vessel 300 via the third pipe 430. (Reference) Figure 4 As shown, the cross-sectional area of ​​the first pipe 410 is larger than that of the second pipe 420, which facilitates the flow of liquid through the first pipe 410 at a larger flow rate and the flow of liquid through the second pipe 420 at a smaller flow rate.

[0049] It should be noted that the cross-sectional area of ​​the first pipe 410 refers to the area of ​​the cross-section of the inner wall of the first pipe 410 cut by a plane perpendicular to the length direction of the first pipe 410. The cross-sectional area of ​​the second pipe 420 refers to the area of ​​the cross-section of the inner wall of the second pipe 420 cut by a plane perpendicular to the length direction of the second pipe 420.

[0050] For example, such as Figure 2 As shown, the mixing device includes multiple storage containers 100 and multiple transfer containers 200, which are connected in a one-to-one correspondence. The multiple transfer containers 200 are connected to the reaction vessel 300 via a third pipeline 430, thereby enabling the reaction vessel 300 to receive liquid from each of the transfer containers 200. The reaction vessel 300 may also be equipped with a stirring mechanism (not shown in the figure), configured to stir the liquid within the reaction vessel 300, thereby improving the mixing uniformity of the various raw materials in the reaction vessel 300 or increasing the reaction efficiency within the reaction vessel 300.

[0051] Specifically, the dispensing device is configured with a first mode and a second mode. In the first mode, the storage container 100 and the transfer container 200 are connected at least through a first pipe 410. That is, the liquid in the storage container 100 can flow into the transfer container 200 through the first pipe 410, or the liquid in the storage container 100 can simultaneously flow into the transfer container 200 through the first pipe 410 and the second pipe 420. In this way, the liquid in the storage container 100 can flow into the transfer container 200 at a large flow rate, thereby increasing the dispensing speed. When the liquid volume or liquid mass in the reaction vessel 300 approaches a set value, the dispensing device is switched from the first mode to the second mode. In the second mode, the storage container 100 and the transfer container 200 are connected through the second pipeline 420. The liquid in the storage container 100 can flow into the transfer container 200 at a small flow rate. When the liquid volume or liquid mass in the transfer container 200 reaches the set value, the valve is closed. Since the instantaneous flow rate in the second pipeline 420 is small, the deviation between the actual value and the set value in the reaction container 300 can be reduced, thereby improving the batching accuracy.

[0052] For example, during the dispensing process, the dispensing device is first switched to a first mode until the liquid in the transfer container 200 approaches the set mass, then switched to a second mode until the liquid in the transfer container 200 reaches the set mass. Optionally, when the liquid in the transfer container 200 reaches 95% of the set mass, the first mode is switched to the second mode, and then liquid continues to be dispensed into the transfer container 200 in the second mode until the set mass is reached.

[0053] In some embodiments, such as Figure 4 As shown, the first pipeline 410 is equipped with a first valve 411, which is configured to open or close the first pipeline 410. The second pipeline 420 is normally open. When the first valve 411 is open, the batching device is in the first mode, and the storage container 100 is connected to the transfer container 200 through both the first pipeline 410 and the second pipeline 420. When the first pipeline 410 is closed, the batching device is in the second mode, and the storage container 100 is connected to the transfer container 200 only through the second pipeline 420. Simply opening or closing the first valve 411 allows the batching device to switch between the first and second modes, making operation simple and convenient.

[0054] For example, in some implementations, reference is made to Figure 6As shown, the first pipeline 410 and the second pipeline 420 are independent pipelines. The two ends of the first pipeline 410 are connected to the storage container 100 and the transfer container 200, respectively, and the two ends of the second pipeline 420 are also connected to the storage container 100 and the transfer container 200, respectively. Each of the first and second pipelines 410 is equipped with a pump drive. For ease of naming, the pump drive on the first pipeline 410 is named the third pump drive 412, and the pump drive on the second pipeline 420 is named the fourth pump drive 423. When the fourth pump drive 423 of the second pipeline 420 is working, the liquid in the second pipeline 420 can continuously flow to the transfer container 200. When the first valve 411 is opened and the third pump drive 412 of the first pipeline 410 is working, the liquid in the first pipeline 410 can flow to the transfer container 200. A pump drive is installed on the first pipeline 410 and the second pipeline 420 respectively, which can individually adjust parameters such as the liquid flow rate in the first pipeline 410 and the second pipeline 420.

[0055] Alternatively, in other embodiments, such as Figures 2 to 4 As shown, the piping assembly 400 also includes a liquid outlet pipe 440 connected to the storage container 100. The inlet ends of the first pipe 410 and the second pipe 420 are both connected to the liquid outlet pipe 440. The storage container 100 is connected to the inlet ends of the first pipe 410 and the second pipe 420 respectively through a single liquid outlet pipe 440. Thus, by providing a second pump drive 442 on the liquid outlet pipe 440, liquid can flow to the transfer container 200 via the first pipe 410 and / or the second pipe 420. Therefore, compared to the previous embodiment, this embodiment achieves liquid transportation of two pipes through a single pump drive.

[0056] Or, refer to Figure 4 As shown, the piping assembly 400 also includes an inlet pipe 450 connected to the transfer container 200. The outlet ends of the first pipe 410 and the second pipe 420 are both connected to the inlet pipe 450. Thus, by providing a pump drive (not shown in the figure) on the inlet pipe 450, liquid can flow to the transfer container 200 via the first pipe 410 and / or the second pipe 420.

[0057] In such Figure 3 and Figure 4 In the illustrated embodiment, the inlet ends of both the first pipe 410 and the second pipe 420 are connected to the outlet pipe 440, and the outlet ends of both the first pipe 410 and the second pipe 420 are connected to the inlet pipe 450. A second pump drive 442 is provided on the outlet pipe 440 to drive the liquid. The first pipe 410, the inlet pipe 450, and the outlet pipe 440 are integrally formed, and the cross-sectional areas of the first pipe 410, the inlet pipe 450, and the outlet pipe 440 are the same, that is, as shown... Figure 2 and Figure 4 As shown, the first pipeline 410, the inlet pipeline 450, and the outlet pipeline 440 are different sections of the same pipeline. This reduces processing costs.

[0058] Furthermore, such as Figure 4 As shown, the piping assembly 400 also includes a second valve 421 disposed in the second pipe 420. The second valve 421 is configured to control the opening or closing of the second pipe 420. By controlling the first valve 411 and the second valve 421 respectively, the first pipe 410 and the second pipe 420 can be controlled separately, thus providing more diverse control modes. For coating solutions with less stringent requirements for mixing accuracy, the first pipe 410 and the second pipe 420 can be directly used in a high-flow mode with both normally open (at which time both the first valve 411 and the second valve 421 are open). For coating solutions with higher requirements for mixing accuracy, the first mode (high flow rate) and the second mode (low flow rate) can be switched in this embodiment for mixing, or the second pipe 420 can be directly used in a low-flow mode with the first pipe 410 normally closed.

[0059] Unlike the embodiments described above, in some other embodiments, reference is made to... Figure 7 As shown, the piping assembly 400 includes a third valve 441 disposed at the junction of the first pipe 410, the second pipe 420, and the outlet pipe 440. The third valve 441 is a three-way valve, including two inlet ends and one outlet end. The two inlet ends are respectively connected to the first pipe 410 and the second pipe 420, and the outlet end is connected to the outlet pipe 440. The two inlet ends can be selectively opened; that is, the third valve 441 is configured to selectively open the first pipe 410 and the second pipe 420, so that one of the first pipe 410 and the second pipe 420 is connected to the outlet pipe 440. With this configuration, switching between the first and second modes can be achieved using only the third valve 441, reducing costs.

[0060] Similarly, the design concept of the three-way valve can also be applied to the connection point of the first pipeline 410, the second pipeline 420, and the inlet pipeline 450 (not shown in the figure). Specifically, the pipeline assembly 400 also includes a fourth valve disposed at the connection point of the first pipeline 410, the second pipeline 420, and the inlet pipeline 450. The fourth valve is configured to selectively open either the first pipeline 410 or the second pipeline 420, so that one of the first pipeline 410 and the second pipeline 420 is connected to the inlet pipeline 450.

[0061] In some embodiments, such as Figure 2 and Figure 5As shown, the dispensing device includes multiple transfer containers 200, which are arranged at intervals along a predetermined direction. The third pipeline 430 includes a first main pipeline 431 and multiple first branch pipelines 432. The first main pipeline 431 is located below each transfer container 200 and extends along the arrangement direction of the transfer containers 200. Each first branch pipeline 432 extends vertically, with one end connected to a corresponding transfer container 200 and the other end connected to the first main pipeline 431. Each first branch pipeline 432 is equipped with a control valve. When the control valve is open, under the influence of gravity, the liquid in the transfer container 200 can flow naturally through the first branch pipeline 432 into the first main pipeline 431. Additionally, the first main pipeline 431 is equipped with a first pump drive 433, which drives the liquid in the first main pipeline 431 to move along a predetermined direction.

[0062] Furthermore, such as Figure 2 As shown, the batching device includes two reaction containers 300, designated as a first reaction container 310 and a second reaction container 320, respectively. The first reaction container 310 and the second reaction container 320 are respectively connected to both ends of a first main channel 431. Figure 2 As shown, the first main channel 431 is also equipped with two pump drives, which are named the first pump drives 433 for easy distinction. It can be understood that one of the first pump drives 433 is used to drive the liquid in the first main channel 431 towards the first reaction vessel 310, and the other first pump drive 433 is used to drive the liquid in the first main channel 431 towards the second reaction vessel 320. In this embodiment, the supply of materials to both reaction vessels 300 is achieved through one first main channel 431, which helps to reduce the number of pipelines in the batching device.

[0063] In addition, the first main path 431 also includes a first reflux section 4311 located between the reaction vessel 300 and the first pump drive 433, such as Figure 2 As shown, the end of the first reflux section 4311 near the reaction vessel 300 is lower than the end of the first reflux section 4311 near the first pump drive 433, so that the liquid in the first reflux section 4311 can flow toward the reaction vessel 300 under the action of gravity.

[0064] More specifically, the first return section 4311 includes an inclined section and a vertical section, such as Figure 2As shown, along the direction of liquid flow from the transfer container 200 to the reaction container 300, the height of the inclined section gradually decreases. The top of the vertical section is connected to the lowest point of the inclined section, and the bottom is connected to the reaction container 300. Thus, the liquid in the first reflux section 4311 can naturally flow through the inclined section and the vertical section under gravity until it reaches the reaction container 300. With this structure, when the first pump drive 433 is closed, the liquid remaining in the first reflux section 4311 can flow into the reaction container 300 under gravity, ensuring that the set mass of liquid flowing out of the transfer container 200 flows into the reaction container 300. This reduces the risk that the prepared liquid may not all flow into the reaction container 300, thereby reducing errors. The inclined section is inclined at 5° to 30° relative to the horizontal plane, preferably 15°.

[0065] Similarly, refer to Figure 3 As shown, a second reflux section 413 is also provided in both the first pipeline 410 and the second pipeline 420. The end of the second reflux section 413 near the transfer container 200 is lower than the end of the second reflux section 413 away from the transfer container 200, so that the liquid in the second reflux section 413 can flow toward the transfer container 200 under the action of gravity.

[0066] In some embodiments, such as Figure 4 As shown, the dispensing device includes a first detector 414 disposed in a first pipeline 410. The first detector 414 is configured to detect the flow rate and / or mass of the liquid passing through the first pipeline 410, thereby facilitating control of the flow rate and / or mass of the liquid flowing into the transfer container 200 via the first pipeline 410. The dispensing device also includes a second detector 422 disposed in a second pipeline 420. The second detector 422 is configured to detect the flow rate and / or mass of the liquid passing through the second pipeline 420, thereby facilitating control of the mass of the liquid flowing into the transfer container 200 via the second pipeline 420. It is understood that the first detector 414 and the second detector 422 can be mass flow meters or other types of flow meters. Optionally, the accuracy of both the first detector 414 and the second detector 422 is 0.01 g / s.

[0067] Optionally, along the direction from the inlet to the outlet of the first pipeline 410, the first valve 411 is positioned downstream of the first detector 414, with a 2cm gap between the first detector 414 and the first valve 411. Along the direction from the inlet to the outlet of the second pipeline 420, the second valve 421 is positioned downstream of the second detector 422, with a 2cm gap between the second detector 422 and the second valve 421. This reduces the measurement errors of the first detector 414 and the second detector 422 caused by disturbances resulting from the opening and closing of the first valve 411 and the second valve 421.

[0068] In some embodiments, the dispensing device includes a third detector (not shown) disposed in the transfer container 200, configured to detect the mass of the liquid within the transfer container 200. The third detector allows for continued detection of the liquid's mass even after it has flowed into the transfer container 200. This ensures that all the dispensed liquid in the transfer container 200 flows into the reaction vessel 300, resulting in a predetermined mass of liquid flowing into the reaction vessel 300. Alternatively, a portion of the liquid in the transfer container 200 can flow into the reaction vessel 300, with the third detector detecting changes in the liquid's mass until a predetermined mass of liquid flows out of the transfer container 200, at which point the outflow stops. Optionally, the third detector is a weighing sensor disposed at the bottom of the transfer container 200, with an accuracy of ±0.1g.

[0069] In some embodiments, the storage container 100 is equipped with a first liquid level sensor (not shown) and a second liquid level sensor (not shown), with the first liquid level sensor located above the second liquid level sensor. The first liquid level sensor facilitates timely stopping of liquid filling in the storage container 100 to prevent overflow. The second liquid level sensor facilitates timely replenishment of liquid to prevent insufficient liquid.

[0070] In some embodiments, such as Figure 1 As shown, the batching device also includes a circulation mechanism 500, which has a first liquid inlet and a first liquid outlet. A second liquid inlet is used to input a heat-conducting medium (not shown in the figure), and a second liquid outlet is used to output the heat-conducting medium. The shell of the reaction vessel 300 is provided with a heat-conducting channel (not shown in the figure), which has a second liquid inlet and a second liquid outlet, both of which are connected to the heat-conducting channel. The first liquid inlet is connected to the second liquid outlet, and the first liquid outlet is connected to the second liquid inlet. Through this arrangement, the reaction vessel 300 can be heated and cooled, thereby allowing the liquid inside the reaction vessel 300 to react at a preset temperature.

[0071] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention. Furthermore, the embodiments of the present invention and the features thereof can be combined with each other unless otherwise specified.
