Abstract
Description
Technical Field
[0001] This application relates to the field of chemical laboratory equipment technology, specifically a structure based on a sulfuric acid overflow guide tank. Background Technology
[0002] In the daily testing and analysis work of chemical laboratories, the dilution of concentrated sulfuric acid and the sampling of the diluted solution are routine but extremely high-risk operations. The diluted sulfuric acid solution still needs to be tested for various physicochemical indicators, such as concentration calibration, impurity analysis, and reactivity testing. This usually requires operators to quantitatively transfer a portion of the sample from the dilution container to the testing container, such as a small beaker, conical flask, or a special sampling bottle.
[0003] However, the existing manual valve-controlled sampling method is prone to problems when handling diluted sulfuric acid solutions. Due to insufficient experience, the flow rate may be too high when manually controlling the valve opening. In particular, sulfuric acid has a higher viscosity than water and a stronger flow inertia, which may exceed the volume of the sampling bottle and cause sulfuric acid overflow, which can easily lead to serious safety accidents.
[0004] Therefore, this application provides a sulfuric acid overflow guide tank structure to solve the above problems. Utility Model Content
[0005] This application provides a sulfuric acid overflow guide tank structure, which aims to solve the problem mentioned in the background art that when operating diluted sulfuric acid solution, the existing manual valve control sampling method is prone to excessive flow due to insufficient experience when manually controlling the valve opening degree, resulting in sulfuric acid overflow.
[0006] To achieve the above objectives, this application provides the following technical solution: a sulfuric acid overflow guide tank structure, including a fixed frame and a base fixedly installed on the fixed frame, a reaction vessel is installed on the upper end of the base, a positioning frame is fixedly installed on the upper end of the fixed frame, a servo motor is provided on the positioning frame, a stirring rod is fixedly installed on the output end of the servo motor, and the stirring rod is inserted from the top cover of the reaction vessel;
[0007] An overflow guiding mechanism is provided at the lower end of the base;
[0008] The overflow guiding mechanism includes a support base mounted on a fixed frame, the support base being detachably connected to a support frame, a diversion box being fixedly installed at the lower end of the support frame, and a splash guard for placing the sampling bottle being provided at the upper end of the support frame. The diversion box has a storage cavity inside, replacing traditional unprotected sampling and constructing an integrated structure for stirring, sampling, and overflow guiding, thus solving the risk of sulfuric acid sampling overflow.
[0009] Preferably, the support frame has a groove for placing the splash guard plate, and a plurality of limiting blocks are evenly distributed in the groove. The splash guard plate has a limiting groove for fitting with the limiting blocks. The splash guard plate adopts this direct installation method, which makes it convenient to remove it for cleaning at any time later.
[0010] Preferably, the inner wall of the drainage box is arc-shaped, and a drainage port is provided at the lower end of the drainage box.
[0011] Preferably, the support base is provided with a guide groove for the support frame to be movably inserted.
[0012] Preferably, the support frame is symmetrically provided with assembly racks, and the support base is provided with positioning pins for threaded connection of the assembly racks, so as to avoid the support frame from sliding due to equipment vibration, operation contact, etc. during the sampling process, which would lead to sampling positioning failure, and ensure the stability of the overflow guiding mechanism during the sampling process.
[0013] The sulfuric acid overflow guide tank structure has a support base fixed to a fixed frame. The support frame is inserted and fixed by moving it back and forth along the guide tank. At the same time, the groove on the support frame is used to place the anti-splash mesh plate. The sampling bottle is manually aligned with the liquid outlet at the bottom of the reaction vessel. If improper operation or excessive discharge causes overflow, the overflowing sulfuric acid will run along the outer wall of the sampling bottle or splash directly onto the anti-splash mesh plate. Finally, it will enter the drainage box through the mesh of the anti-splash mesh plate, where the overflowing sulfuric acid is collected, preventing the overflowing sulfuric acid from flowing directly to the vicinity of the test area and causing pollution.

[0020] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0021] This embodiment provides a structure based on a sulfuric acid overflow guide tank, such as... Figure 1-4 As shown, the sulfuric acid overflow guide tank structure includes a fixed frame 1 and a base 2 fixedly installed on the fixed frame 1. A reaction vessel 3 is installed on the upper end of the base 2. A positioning frame 4 is fixedly installed on the upper end of the fixed frame 1. A servo motor 5 is installed on the positioning frame 4. A stirring rod 6 is fixedly installed on the output end of the servo motor 5. The stirring rod 6 is inserted from the top cover of the reaction vessel 3.
[0022] An overflow guide mechanism 7 is provided at the lower end of the base 2;
[0023] The overflow guiding mechanism 7 includes a support base 71 mounted on a fixed frame 1. The support base 71 is detachably connected to a support frame 73. A diversion box 75 is fixedly mounted on the lower end of the support frame 73. A splash guard 76 for placing sampling bottles is provided on the upper end of the support frame 73. A storage cavity is provided inside the diversion box 75.
[0024] Specifically, the fixed frame 1 provides equipment support, the base 2 carries the reaction vessel 3, the positioning frame 4 fixes the servo motor 5, the stirring rod 6 realizes sulfuric acid dilution and stirring, in the overflow guiding mechanism 7, the support seat 71 is fixed to the fixed frame 1, the support frame 73 is adapted to the support seat 71 through the guide groove 72, the anti-splash mesh plate 76 places the sampling bottle, and the diversion box 75 collects the overflow sulfuric acid.
[0025] The support frame 73 has a groove 731 for placing the splash guard 76. The groove 731 is provided with a number of limiting blocks 732 at equal intervals. The splash guard 76 has a limiting groove 77 for fitting with the limiting blocks 732.
[0026] More specifically, the groove 731 on the support frame 73 is used to accurately place the anti-splash mesh plate 76. The limiting block 732 in the groove 731 is nested with the limiting groove 77 on the anti-splash mesh plate 76 to restrict the movement of the anti-splash mesh plate 76 in the horizontal direction, ensuring that the sampling bottle placed on the anti-splash mesh plate 76 can be stably aligned with the sampling and drainage position. The limiting block 732 is cuboid in shape.
[0027] The inner wall of the drainage box 75 is arc-shaped, and a drainage port 751 is provided at the lower end of the drainage box 75.
[0028] Furthermore, the inner wall of the drainage box 75 is designed with an inner arc shape. When sulfuric acid overflows, the guiding effect of the inner arc surface is used to guide the sulfuric acid along the arc surface into the storage cavity, and finally converges to the drain port 751 at the lower end for centralized discharge and collection. The drain port 751 is a DN15 standard interface that can be connected to PVC anti-corrosion pipelines. By effectively collecting the sulfuric acid that has overflowed from the sampling bottle, it is prevented from flowing randomly and corroding equipment, polluting the environment, or harming personnel, and the overflowing sulfuric acid is guided to a controllable discharge path.
[0029] The support base 71 has a guide groove 72 for the support frame 73 to be movably inserted.
[0030] It should be noted that the guide groove 72 on the support base 71 provides a sliding track for the support frame 73. The support frame 73 can be moved back and forth along the guide groove 72 for insertion and fixation. The cross-section of the guide groove 72 is rectangular. The support frame 73 slides in cooperation with the guide groove 72 to ensure the stability of the support frame 73 during the sliding process.
[0031] The support frame 73 is symmetrically provided with assembly frames 733, and the support base 71 is provided with positioning pins 74 for threaded connection of the assembly frames 733.
[0032] It is worth mentioning that the mounting bracket 733 on the support frame 73 is threadedly connected to the positioning pin 74 on the support base 71. After the support frame 73 is adjusted to the appropriate position, the positioning pin 74 is tightened, and the locking force of the thread is used to fix the support frame 73 on the support base 71 to prevent it from sliding or displacing.
[0033] In use, the support base 71 is fixed to the fixing frame 1. The support frame 73 is inserted and fixed by moving it back and forth along the guide groove 72. At the same time, the groove 731 on the support frame 73 is used to place the anti-splash mesh plate 76. The sampling bottle is manually aligned with the liquid outlet at the bottom of the reaction container 3. When the valve of the reaction container 3 is opened to discharge the diluted sulfuric acid liquid, if the operation is improper or too much is discharged and overflow occurs, the overflowing sulfuric acid will flow along the outer wall of the sampling bottle or directly splash onto the anti-splash mesh plate 76. Finally, it will enter the drainage box 75 through the mesh of the anti-splash mesh plate 76, and the drainage box 75 will collect the overflowing sulfuric acid to prevent the overflowing sulfuric acid from flowing directly to the vicinity of the test area and causing pollution.
[0034] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
