Description

Technical Field

[0001] The present application relates to the technical field of acid liquid supply equipment, and in particular to a mobile acid liquid control device and a control system thereof. Background Art

[0002] At present, a large amount of acid is used in chemistry, metallurgy, pharmaceuticals and other industries. Commonly used acidic liquids include hydrochloric acid, nitric acid, hydrofluoric acid and sulfuric acid. These acidic liquids are highly corrosive and oxidizing, so the acidic liquids must be stored safely. When taking the acid, a pump is used to extract the acid. This process seems simple, but it is actually very dangerous. In the existing technology, each acid storage barrel is equipped with an acid supply port. When using multiple acidic liquids, multiple acid storage barrels need to be configured and acid is supplied separately. This acid supply is not only inefficient, but also increases the cost investment of production equipment and occupies production site space. In addition, the acid supply pump is often placed in the same space as the acid storage barrel. Over time, exposure to the enclosed acidic space will cause severe corrosion to the acid supply pump, thereby reducing the service life of the instrument.

[0003] In view of this, it is necessary to design a mobile acid liquid control device and its control system to solve the above problems. Utility Model Content

[0047] In existing technology, acid supply pumps are often placed in the same space as acid storage tanks. Over time, exposure to the enclosed acidic environment can cause severe corrosion to the pumps, reducing the lifespan of the equipment. Furthermore, the highly corrosive nature of acid requires strict control over its use. Therefore, it is crucial to rationally design equipment to extend the lifespan of the acid supply equipment while ensuring safe control of acid inflow and outflow.

[0048] In order to solve the above-mentioned technical problems, the present application provides a mobile acid liquid control system, in which a shut-off valve device 112 is arranged on the pipeline 4 in the acid liquid storage bin 1, wherein the shut-off column 1122 is moved to cut off the passage of the pipeline 4 to control the inflow and outflow of the acid liquid, prevent abnormal acid extraction, and avoid acid volatilization in the pipeline 4, thereby delaying the service life of the pipeline 4 and other instruments; in addition, by setting the acid liquid storage bin 1, the liquid adding handle 2, and the intelligent acid adding host 3, and designing a mobile acid liquid control and control system, it is ensured that the accuracy of the acid supply and the safety of the operation site are improved.

[0049] For the convenience of description, the following embodiments are described by taking a mobile acid liquid control system according to an embodiment of the present application as an example.

[0050] Please refer to Figure 1 , Figures 1 to 4 A schematic structural diagram of a mobile acid liquid control device provided in an embodiment of the present application includes: an acid liquid storage bin 1, a liquid filling handle 2 connected to the acid liquid storage bin 1 via a pipe 4, and an intelligent acid filling host 3 disposed on the pipe 4; the intelligent acid filling host 3 is located between the acid liquid storage bin 1 and the liquid filling handle 2; one end of the pipe 4 is located in the liquid storage container 111; and the other end of the pipe 4 is located in the liquid filling handle 2;

[0051] Several acid adding instruments are provided inside the acid storage bin 1;

[0052] The acid adding apparatus comprises a liquid storage container 111 and a shut-off valve device 112 provided on the pipeline 4;

[0053] like Figures 3-4 As shown, the shut-off valve device 112 includes a fixed sleeve 1121 provided on the pipeline 4, a shut-off column 1122 moving in the fixed sleeve 1121, a driving device for driving the shut-off column 1122 to move, and a fixed plate provided on the inner wall of the acid storage bin 1 and connected to the driving device;

[0054] The pipe 4 passes through the fixed sleeve 1121 ; when the truncation column 1122 moves, one end of the truncation column 1122 abuts against the side wall of the pipe 4 and can cut off the passage of the pipe 4 .

[0055] The liquid adding handle 2 includes a control valve 21 located on the pipe 4 inside the liquid adding handle 2 and a control switch 22 for controlling the flow direction of the acid liquid in the pipe 4; the control switch 22 includes a switch 1 and a switch 2.

[0056] In this way, after the extraction of the acid is completed, the truncation column 1122 is driven by the driving device to move, thereby cutting off the passage of the pipeline 4. This not only controls the inflow and outflow of the acid and prevents abnormal acid extraction; it also prevents the acid from volatilizing in the pipeline 4 and prolongs the overall service life of the instrument.

[0057] Furthermore, in the embodiments of the present application, Figure 1 As shown, the shut-off valve device 112 is located in the acid storage tank 1; this reduces the volatilization distance of the acid in the pipeline 4, and can reduce the maintenance cost of the equipment outside the acid storage tank 1 during maintenance.

[0058] Furthermore, in this embodiment of the present application, the drive device includes a lead screw 11231 connected to the other end of the truncation column 1122 and a stepper motor 11232 for driving the lead screw 11231. The stepper motor 11232 is connected to the inner wall of the acid storage bin 1. The threads in the rotor of the stepper motor 11232 engage with the lead screw 11231. When the stepper motor 11232 rotates, the rotor drives the lead screw 11231 to rotate via the internal threads, causing the lead screw 11231 to move linearly, and the lead screw 11231 further drives the truncation column 1122 to move linearly.

[0059] Furthermore, in an embodiment of the present application, the mobile acid liquid control device further includes: an acid supply pump 5 disposed on the pipeline 4; the acid supply pump 5 is located outside the cavity of the acid liquid storage bin 1. The acid supply pump 5 can not only pump the acid liquid from the liquid storage container 111 to the liquid filling handle 2, but also reverse the acid liquid from the liquid filling handle 2 back to the liquid storage container 111. Compared to the prior art method of placing the acid supply pump 5 within the cavity of the acid liquid storage bin 1, this can prevent the acid supply pump 5 from being exposed to a high-strength acid environment, significantly improving the service life of the acid supply pump 5.

[0060] Furthermore, in the embodiment of the present application, a plurality of universal wheels 6 are provided at the bottom end of the acid storage bin 1; this allows the acid storage bin 1 to be easily moved in all directions on flat ground, thereby improving the flexibility of the storage bin and saving labor.

[0061] like Figure 5 As shown, in a second aspect, the present application also provides a mobile acid liquid control and management system, which adopts the above-mentioned mobile acid liquid control device and controls the mobile acid liquid control device;

[0062] The intelligent acid adding host 3 is connected to the acid storage bin 1 and the liquid adding handle 2 respectively through electrical signals;

[0063] The intelligent acid adding host 3 includes a signal receiving system and a control unit connected to the signal receiving system via an electrical signal;

[0064] The signal receiving system is used to receive the liquid supply signal sent by the liquid filling handle 2;

[0065] The signal receiving system is used to receive the on / off status signal of the acid supply pump 5;

[0066] The control unit is used to control the delivery state of the acid solution in the acid solution storage bin 1 .

[0067] The control unit is connected to the shutoff valve device 112 via electrical signals, and the control unit is used to control the opening and closing state of the shutoff valve device 112 (that is, the control unit is connected to the driving device in the shutoff valve device 112 via electrical signals, and the control unit is used to control the movement state of the driving device);

[0068] The control unit is connected to the acid supply pump 5 via an electrical signal, and the control unit is used to control the on / off state of the acid supply pump 5;

[0069] After receiving the on / off status of the acid supply pump 5, the signal receiving system transmits the information to the control unit, and the control unit controls the on / off status of the shut-off valve device 112;

[0070] The signal receiving system is used to receive the signal of the control switch 22 on the liquid filling handle 2;

[0071] The control unit is used to control the opening and closing state of the control valve 21 on the liquid filling handle 2.

[0072] Furthermore, the acid addition logic of the control switch 22: the intelligent acid addition host 3 also includes a timer, and the timer threshold is set to distinguish between short-press and long-press operations of the control switch 22; after the signal receiving system receives the short-press signal of switch 1, it transmits the signal to the control unit, and the control unit controls the rotation time of the acid supply pump 5 (the rotation time of the acid supply pump 5 corresponds to the corresponding acid volume); at the same time, the control unit also opens the control valve 21 on the corresponding pipe 4 in the liquid addition handle 2; thus, a quantitative acid addition is performed. After the signal receiving system receives the long-press signal of switch 1, it transmits the signal to the control unit, and according to the time interval set by the intelligent acid addition host 3, the control unit controls the single rotation time and rotation cycle change of the acid supply pump 5 (the single rotation time of the acid supply pump 5 corresponds to the corresponding acid volume); at the same time, the control unit also opens the control valve 21 on the corresponding pipe 4 in the liquid addition handle 2; thus, multiple quantitative acid additions are performed at periodic intervals.

[0073] After receiving the short-press signal of switch 2, the signal receiving system transmits the signal to the control unit, which then controls the direction of the acid supply pump 5 to reverse the flow of the acid from the liquid adding handle 2 back to the liquid storage container 111. At the same time, the control unit also closes the control valve 21 on the corresponding pipe 4 in the liquid adding handle 2. After receiving the long-press signal of switch 2, the signal receiving system transmits the signal to the control unit, which controls the direction of the acid supply pump 5 to reverse the flow of the acid from the liquid adding handle 2 back to the liquid storage container 111, clearing the remaining acid in the pipe 4. The control unit again controls the direction of the acid supply pump 5 to pump the acid from the liquid storage container 111 to the liquid adding handle 2, filling the entire pipe 4.

[0074] In this way, by setting up an intelligent acid adding host 3 that is respectively connected to the acid storage tank 1 and the liquid adding handle 2 by signal, the system can accurately control the supply of acid according to actual needs to avoid overdose or underdose; the control unit can monitor and control each component in the system, facilitating maintenance and troubleshooting; the operator can remotely control the supply of acid through the liquid adding handle 2, improving the convenience and safety of operation; by controlling the shut-off valve, acid supply pump 5 and other devices, the system can quickly cut off the acid supply in the event of an abnormal situation to prevent accidents. This mobile acid management and control system realizes the linkage control of each component through electrical signals, improving the automation level, operational safety and work efficiency of acid filling.

[0075] like Figures 1 to 5 As shown, the working principle of a mobile acid liquid control device and its control system provided by this application is described below:

[0076] The four liquid storage containers 111 in the acid storage bin 1 are respectively equipped with four different acid solutions. First, the target acid solution is selected on the interface of the intelligent acid adding host 3, and after a short press of the switch on the liquid adding handle 2, the signal receiving system in the intelligent acid adding host 3 receives the information and transmits the signal to the control unit, which then turns on and controls the rotation time of the acid supply pump 5 (the rotation time of the acid supply pump 5 corresponds to the corresponding acid solution volume); at the same time, the control unit also turns on the control valve 21 on the corresponding pipeline 4 in the liquid adding handle 2; at the same time, after the signal receiving system receives the open state of the acid supply pump 5, it transmits the information to the control unit, which controls the cutoff column 1122 to move away from the pipeline 4 it is against, so that the cutoff valve device 112 is in an open circuit state; thus, a quantitative acid addition is performed.

[0077] Long press switch 1 on the liquid adding handle 2. After receiving the signal, the signal receiving system transmits the signal to the control unit. According to the time interval set by the intelligent acid adding host 3, the control unit controls the single rotation time and rotation cycle change of the acid supply pump 5 (the single rotation time of the acid supply pump 5 corresponds to the corresponding acid volume); at the same time, the control unit will also open the control valve 21 on the corresponding pipe 4 in the liquid adding handle 2; at the same time, after receiving the opening state of the acid supply pump 5, the signal receiving system transmits the information to the control unit, and the control unit controls the shut-off column 1122 to move away from the pipe 4 it is against, so that the shut-off valve device 112 is in an open state; in this way, multiple quantitative acid additions are performed at periodic intervals.

[0078] Short press switch 2 on the filling handle 2. After receiving the signal, the signal receiving system transmits the signal to the control unit, and the control unit controls the direction of the acid supply pump 5. At the same time, the control unit also closes the control valve 21 on the corresponding pipe 4 in the filling handle 2. At the same time, after receiving the open state of the acid supply pump 5, the signal receiving system transmits the information to the control unit, and the control unit controls the shut-off column 1122 to move away from the pipe 4 it is against, so that the shut-off valve device 112 is in an open state. In this way, all the acid is pumped back from the filling handle 2 to the liquid storage container 111 (no acid remains in the pipe 4).

[0079] Long press switch 2 on the filling handle 2. After receiving the signal, the signal receiving system transmits the signal to the control unit, and the control unit controls the direction of the acid supply pump 5. At the same time, after receiving the on state of the acid supply pump 5, the signal receiving system transmits the information to the control unit. The control unit controls the shut-off column 1122 to move away from the pipe 4 it is resisting, so that the shut-off valve device 112 is in an open state, thereby pumping the acid liquid from the filling handle 2 to the liquid storage container 111 until the remaining acid liquid in the pipe 4 is emptied. Then the control unit will control the direction of the acid supply pump 5 again, and pump the acid liquid from the liquid storage container 111 to the filling handle 2, filling the entire pipe 4, performing pre-filling, and being in a state ready for liquid extraction.

[0080] The state of the acid supply pump 5 is interrelated with the state of the shut-off valve device 112: when the acid supply pump 5 is in the open state, the control unit receives a signal to control the shut-off valve device 112 to be in the open state; when the acid supply pump 5 is in the closed state, the control unit receives a signal to control the shut-off valve device 112 to be in the closed state.

[0081] During the acid removal process, the indicator light on the liquid filling handle 2 will flash.

[0082] After the liquid is taken, click the end operation on the intelligent acid adding host 3, and the control unit closes the acid supply pump 5 and the shut-off valve device 112 on the corresponding acid adding instrument after receiving the signal.

[0083] Similarly, repeat the above operation when taking other acid solutions, which will not be described here.

[0084] Please also refer to Figures 1 to 5 According to one or more embodiments of the present application, the mobile acid liquid control device provided by the present application includes an acid liquid storage bin 1, a liquid adding handle 2, and an intelligent acid adding host 3; a shut-off valve device 112 is provided on the pipeline 4 in the acid liquid storage bin 1, wherein the shut-off column 1122 is moved to cut off the passage of the pipeline 4 to control the inflow and outflow of acid, prevent abnormal acid extraction, and prevent acid volatilization in the pipeline 4, thereby delaying the overall service life of the instrument; in addition, a mobile acid liquid control and control system is designed based on the mobile acid liquid control device to accurately control the supply of acid liquid according to actual needs, avoid excessive or insufficient acid, improve the accuracy of acid supply, and the safety of the operation site. This mobile acid liquid control and control system realizes the linkage control of various components through electrical signals, thereby improving the automation degree, operation safety and work efficiency of acid liquid filling.

The above-mentioned embodiments are merely examples, and any embodiments having substantially the same structure and effect as the technical concept within the scope of the present application are all included in the technical scope of the present application.
