Description

Technical Field

[0001] This utility model relates to the field of chemical production equipment technology, and in particular to a water volume control system for a reaction vessel. Background Technology

[0002] Currently, water is one of the most commonly used solvents in chemical production, and the amount of water added often needs to be controlled, especially in the process of compounding and dissolving materials.

[0003] Water volume is typically controlled by either flow rate control or weighing. In large-scale production, weighing control usually involves using a reactor weighing module, which is costly, prone to damage, and requires regular adjustment. This is especially problematic for materials where color is the primary indicator, making it difficult to adjust the water volume using a weighing module. Flow control, on the other hand, cannot meet the requirement of rapid color control in production.

[0004] Therefore, it is necessary to propose a water control system suitable for material production processes where color is the primary indicator. Utility Model Content

[0005] In order to overcome at least one of the defects described in the prior art, the purpose of this utility model is to provide a water volume control system for a reactor, so as to solve the problem of inconvenient water volume control in the production of materials with color as the first indicator in the prior art.

[0006] The technical solution adopted by this utility model to solve its problem is:

[0007] According to one aspect of the present invention, the present invention provides a water control system for a reaction vessel, comprising: a color detection device disposed inside the reaction vessel and immersed in the liquid in the reaction vessel; a water supply device including a water supply pipe connected to the interior of the reaction vessel; a solenoid valve disposed on the water supply pipe; and a control module electrically connected to the color detection device and the solenoid valve.

[0008] Optionally, the upper side of the reactor is provided with a first opening, and a first cover plate is detachably fixed to the first opening. A connecting rod is passed through the first cover plate, with the first end of the connecting rod extending toward the interior of the reactor and the second end of the connecting rod located outside the reactor. A color detection device is provided at the first end of the connecting rod.

[0009] Optionally, the color detection device can be detachably fixed to the first end.

[0010] Optionally, a mounting base is fixed to the first end of the connecting rod. The mounting base is provided with a clamp and a threaded fastener. The clamp surrounds the color detection device and is locked by the threaded fastener.

[0011] Optionally, the first cover plate is fixed to the reactor via a flange.

[0012] Optionally, the first cover plate is provided with a second opening larger than the connecting rod, so that the connecting rod can slide relative to the first cover plate, and the opening direction of the second opening is along the depth direction inside the reactor; the first cover plate is provided with a locking device, which fixes the connecting rod to the first cover plate.

[0013] Optionally, the locking device includes a locking screw, and a connecting plate is fixedly connected to the first cover plate. The connecting plate is provided with a threaded hole, and the locking screw is threaded into the threaded hole and abuts against the connecting rod.

[0014] Optionally, a third opening is provided on the upper side of the reactor, and a second cover plate is fixed to the third opening. The water supply pipe passes through the second cover plate and extends into the interior of the reactor.

[0015] Optionally, the water supply device also includes a flow control valve, which is connected to the water supply pipe and electrically connected to the control module, and can adjust the water supply flow rate of the water supply pipe under the control of the control module.

[0016] Optionally, the water supply device also includes a pressure relief valve, which is connected to the water supply pipe and releases pressure and drains water when the solenoid valve is closed.

[0017] As can be seen from the above technical solution, the embodiments of this utility model have at least the following advantages and positive effects:

[0018] This invention involves installing a color detection device in a reaction vessel to sample and detect the mixed liquid. The detected data or color comparison results are then transmitted to a control module. The control module determines the comparison result based on the color detection device's comparison or by comparing the detected data with preset data. It then controls the solenoid valve: if the detected color exceeds a preset color range, the solenoid valve opens to add water; if the detected color falls within the preset color range, the solenoid valve closes.

[0019] Therefore, the color detection device performs real-time sampling and detection during the mixing process in the reactor and controls the switching solenoid valve in real time, so that the color of the final material is within the controlled index range, ensuring high-efficiency material production.

[0029] Example

[0030] See Figures 1 to 4 This utility model discloses a water volume control system for a reaction vessel, including a color detection device 2, a water supply device, a switch solenoid valve 4, and a control module 5, wherein the color detection device 2 is installed inside the reaction vessel 1 and immersed in the liquid in the reaction vessel 1.

[0031] The water supply device includes a water supply pipe 3, which is connected to the interior of the reaction vessel 1;

[0032] The solenoid valve 4 is installed on the water supply pipe 3;

[0033] The control module 5 is electrically connected to the color detection device 2 and the solenoid valve 4.

[0034] The mixed liquid in the reactor 1 is mixed under the action of the stirring paddle. The color detection device 2, which is immersed in the liquid, can sample and analyze the mixed liquid. Specifically, the color detection device 2 can detect the color of the liquid and convert the detected color into corresponding detection data information and transmit it to the control module 5.

[0035] Of course, the system also includes a power supply (not shown) to power electrical components or equipment such as the color detection device 2, the solenoid valve 4, and the control module 5.

[0036] Optionally, the color detection device 2 can be a colorimeter with a built-in processor. The colorimeter can perform digital-to-analog conversion to obtain the detection value. The internal processor can also perform threshold comparison between the detection value and a preset colorimetric range. If the colorimetric range is met, a positive result signal is output; otherwise, a negative result signal is output. The colorimeter ultimately transmits the threshold comparison result signal to the control module 5, which controls the opening and closing state of the solenoid valve 4. In response to a positive result signal, the solenoid valve 4 is closed; in response to a negative result signal, the opening and closing state of the solenoid valve 4 is not changed, and the solenoid valve 4 remains open.

[0037] Optionally, or of course, a colorimeter with only an analog-to-digital conversion module can be selected. The colorimeter can perform digital-to-analog conversion to obtain a detection value and transmit the detection value to the control module 5. The control module 5 has a preset colorimetric range value. The control module 5 compares the detection value with the preset colorimetric range value for a threshold: if it matches the colorimetric range value, the control solenoid valve 4 is closed; otherwise, the on / off state of the solenoid valve 4 is not changed, and the solenoid valve 4 remains open.

[0038] The specific selection method depends on the actual situation; existing instruments can be selected and adapted accordingly. This application does not impose any restrictions on this.

[0039] Optionally, a first opening is provided on the upper side of the reactor 1, and a first cover plate 6 is detachably fixed to the first opening. A connecting rod 7 is passed through the first cover plate 6. The first end 701 of the connecting rod 7 extends toward the interior of the reactor 1, and the second end 702 of the connecting rod 7 is located outside the reactor 1. The color detection device 2 is provided at the first end 701 of the connecting rod 7.

[0040] By setting the connecting rod 7, a stable installation base can be provided for the color detection device 2. Since the first cover plate 6 is detachable, the color detection device 2 does not need to be installed inside the reactor 1. The color detection device 2 can be installed inside the reactor 1 by removing the first cover plate 6 and connecting rod 7, which reduces the installation difficulty and facilitates promotion.

[0041] Alternatively, the connecting rod 7 is a hollow rod, and the color detection device 2 includes a probe and an electrical connection wire. The probe is fixed to the first end 701 of the connecting rod 7, and the electrical connection wire is electrically connected to the probe and extends through the interior of the connecting rod 7 to the exterior of the reactor 1 to transmit electrical signals and connect to a power source to supply power to the probe.

[0042] Optionally, the connecting rod 7 can be made of rigid hollow tubing. Furthermore, the connecting rod 7 can be made of insulating material. Choosing insulating tubing can reduce weight on the one hand, and prevent direct electrical conduction between the reactor 1 and the probe when there is leakage in the wires or static electricity in the outside.

[0043] Optionally, the color detection device 2 is detachably fixed to the first end 701. By detachably connecting the color detection device 2 to the first end 701 of the connecting rod 7, it is convenient to maintain, replace or repair the color detection device 2.

[0044] Optionally, a mounting base 8 is fixed on the first end 701 of the connecting rod 7. The mounting base 8 is provided with a clamp 9 and a threaded fastener 10 connected together. The clamp 9 surrounds the color detection device 2 and is locked by the threaded fastener 10.

[0045] The color detection device 2 can be fixed to the mounting base 8 of the first end 701 of the connecting rod 7 by means of the clamp 9 and the threaded fastener 10; the clamp 9 can also be loosened by releasing the threaded fastener 10 to remove the color detection device 2 from the mounting base 8, which facilitates the inspection and maintenance of the color detection device 2.

[0046] Optionally, the first cover plate 6 is fixed to the reactor 1 by a flange. The flange facilitates the installation of the first cover plate 6 and the reactor 1, and ensures a stable and secure connection.

[0047] Optionally, the first cover plate 6 is provided with a second opening larger than the connecting rod 7, so that the connecting rod 7 can slide relative to the first cover plate 6, and the opening direction of the second opening is along the depth direction inside the reactor 1; the first cover plate 6 is provided with a locking device 11, which fixes the connecting rod 7 to the first cover plate 6.

[0048] The connecting rod 7 can be fixed to the first cover plate 6 by the locking device 11. When it is necessary to adjust the length of the connecting rod 7 extending into the reactor 1, the locking device 11 can be released so that the connecting rod 7 can slide relative to the first cover plate 6. After the adjustment is completed, the connecting rod 7 can be locked to the first cover plate 6 by the locking device 11.

[0049] Optionally, the locking device 11 includes a locking screw 1101, and a connecting plate 13 is fixedly connected to the first cover plate 6. The connecting plate 13 is provided with a threaded hole, and the locking screw 1101 is threadedly connected to the threaded hole and abuts against the connecting rod 7.

[0050] The connecting plate 13 serves as the mounting base for the locking screw 1101. The locking screw 1101 abuts against the connecting rod 7 to lock and fix the connecting rod 7. When it is necessary to unlock the connecting rod 7, simply loosen the locking screw 1101 in the first direction to move it away from the connecting rod 7 to reduce the pressure on the connecting rod 7 or to completely disengage it from the connecting rod 7. Conversely, by rotating the locking screw 1101 in the opposite direction in the second direction, the locking screw 1101 can abut against the connecting rod 7 to lock the connecting rod 7.

[0051] Optionally, a third opening is provided on the upper side of the reactor 1, and a second cover plate 14 is fixed to the third opening. The water supply pipe 3 passes through the second cover plate 14 and extends into the interior of the reactor 1.

[0052] The second cover plate 14 provides a foundation for the installation of the water supply pipe 3, reducing the difficulty of installation.

[0053] Optionally, the water supply device also includes a flow control valve 15, which is connected to the water supply pipe 3 and electrically connected to the control module 5, and can adjust the water supply flow of the water supply pipe 3 under the control of the control module 5.

[0054] When the color detection device 2 detects that the color of the liquid is within the measurement range, the control module 5 can adjust the opening size of the flow control valve 15 to regulate the water flow rate in the water supply pipe 3. If the measured color is not within the measurement range, the opening size of the flow control valve 15 can be increased or maintained. If the measured color is within the measurement range, the opening size of the flow control valve 15 can be decreased to reduce the water supply of the water supply pipe 3, thus preparing for the next step of the control module 5 to control the solenoid valve 4. This avoids the instantaneous pressure reduction that would occur if the solenoid valve 4 is directly closed, which could cause vibration in the water supply pipe 3 and reduce damage to the water supply pipe 3.

[0055] Optionally, the water supply device also includes a pressure relief valve 16, which is connected to the water supply pipe 3 and releases pressure and drains water when the solenoid valve 4 is closed.

[0056] When the control module 5 controls the solenoid valve 4 to close, the water pressure in the water supply pipe 3 will increase. The pressure relief valve 16 can provide a pressure relief path to relieve the pressure in the water supply pipe 3 and prevent damage to the water supply pipe 3.

[0057] The implementation process and principle of this embodiment:

[0058] In this embodiment, the color detection device 2 is used to sample and detect the liquid mixed in the reaction vessel 1, and then the detection data or color comparison result is transmitted to the control module 5. The control module 5 directly controls the switch solenoid valve 4 after determining the comparison result based on the comparison result of the color detection device 2 or by comparing the detection data with preset data: if the detected color exceeds the preset color range, the switch solenoid valve 4 is opened to add water; if the detected color is within the preset color range, the switch solenoid valve 4 is closed.

[0059] Because the color detection device 2 can perform real-time sampling and detection during the mixing process of the reactor 1 and control the solenoid valve 4 in real time, the color of the final material is within the controllable index range, ensuring high-efficiency material production.

[0060] In summary, the water control system applied to the reactor in this application is characterized by high efficiency and real-time performance, and is suitable for the mixing process of colored liquids.

[0061] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
