Description

Technical Field

[0001] This utility model relates to the field of solution stirring technology, specifically to a stirring tank for the production of sodium hydroxide solution. Background Technology

[0002] Sodium hydroxide is a strong alkaline and highly corrosive substance. It can be used as an acid neutralizer, complexing masking agent, precipitant, precipitation masking agent, color developer, saponifying agent, peeling agent, detergent, etc., and has a wide range of applications. An existing patent describes a solution mixing and stirring tank (patent publication number CN221982140U), which includes a tank body, a rotating drum, a turntable, two rotating shafts, a feeding pipe, a geared motor, and a servo motor. The rotating drum is vertically arranged in the tank body and has multiple connecting pipes with stirring blades on them. The bottom of the rotating drum is a blind end, and a stirring frame is located below it. The turntable is rotatably connected to the upper end of the rotating drum, and a first gear is fixed on the turntable. The two rotating shafts are respectively connected to the rotating drum for transmission, and the top ends of the shafts are rotatably connected to the turntable. Spiral stirring blades are mounted on the shafts. The feeding pipe is inserted inside the rotating drum. The output shaft of the geared motor is connected to the rotating drum for transmission, and the output shaft of the servo motor is connected to a rotating rod. A second gear meshing with the first gear is installed at the bottom of the rotating rod. This device not only prevents concentrated sulfuric acid from settling at the bottom of the tank and promotes chemical reactions, but also improves fluid circulation and ensures uniform mixing of materials.

[0003] Regarding the aforementioned technologies, the inventors believe that the following defects exist: although power can be output using a geared motor, the lack of an effective oscillating mixing structure makes it easy for the solution inside the container to rush to the inner wall of the container during mixing, resulting in incomplete mixing and precipitation. Therefore, we propose a stirring tank for sodium hydroxide solution production to solve the above-mentioned problems. Utility Model Content

[0004] To address the shortcomings of existing technologies, this invention provides a stirring tank for the production of sodium hydroxide solution, which solves the problem that the lack of an effective swaying mixing structure in existing tanks makes it easy for the molten liquid inside the tank to rush to the inner wall of the tank during mixing, resulting in incomplete mixing and precipitation.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a stirring tank for producing sodium hydroxide solution, comprising a containing mechanism, the main body of which is a tank structure with a one-way opening at the top, a support mechanism fixedly connected to the top of the containing mechanism, the main body of which is a U-shaped structure with a one-way opening at the bottom, a side plate assembly fixedly connected to the front end of the transverse component in the support mechanism, a servo motor A mounted on the front end face of the side plate assembly, and an output shaft provided on the rear side of the servo motor A.

[0006] Preferably, a support component is fixedly connected to the bottom surface of the receiving mechanism, and the main body of the support component is a hollow structure.

[0007] Preferably, the support components are provided in three places, and the three support components are fixedly connected to the bottom end face of the receiving mechanism in a ring array.

[0008] Preferably, each of the three support components is fixedly connected to a foot component on its bottom surface, and the foot components and the support components together form a support structure for the housing mechanism.

[0009] Preferably, a through hole is provided on the bottom surface of the receiving mechanism, and a drain assembly is fixedly connected inside the through hole. The drain assembly has a bidirectional through structure on both the upper and lower sides.

[0010] Preferably, a valve body assembly is fixedly connected to the outside of the drainage assembly. The valve body assembly is a solenoid valve structure, and the valve body assembly and the drainage assembly together form a drainage structure.

[0011] Preferably, a base mechanism is installed on the rear output shaft of the servo motor A. The base mechanism is rotatably connected to the inner side of the support mechanism. A servo motor B is installed on the top surface of the base mechanism. A mixing component is installed on the bottom output shaft of the servo motor B. The servo motor B and the mixing component together form a mixing structure for the solution.

[0012] Beneficial effects

[0013] This invention provides a stirred tank for the production of sodium hydroxide solution. Compared with the prior art, it has the following advantages:

[0014] This stirring tank for sodium hydroxide solution production uses a servo motor A to drive the base mechanism, causing the mixing components to oscillate during stirring. This unique design effectively prevents the solution from simply rushing towards the inner wall of the container, allowing the solution to flow and mix thoroughly inside the tank. This significantly improves the uniformity of the solution, reduces sedimentation, and enhances the production quality of the sodium hydroxide solution.

[0015] This mixing tank for sodium hydroxide solution production features a hollowed-out support structure at the bottom of the containment mechanism. This not only reduces the overall weight of the tank and saves material costs but also maintains its support strength. Furthermore, the three support components are arranged in a circular array, working in conjunction with the foot support components to make the mixing tank more stable, significantly enhancing its stability compared to traditional support structures.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-6 This utility model provides a technical solution: a stirring tank for producing sodium hydroxide solution, including a containing mechanism 1. The main body of the containing mechanism 1 is a tank structure with a one-way opening at the top. A support mechanism 2 is fixedly connected to the top of the containing mechanism 1. The main body of the support mechanism 2 is a U-shaped structure with a one-way opening at the bottom. A side plate assembly 201 is fixedly connected to the front end of the transverse component in the support mechanism 2. A servo motor A202 is installed on the front end surface of the side plate assembly 201. An output shaft is provided on the rear side of the servo motor A202.

[0025] The U-shaped structure of the support mechanism 2 facilitates the installation of other components, enhances the overall structural stability, and helps to ensure the smooth operation of the mixing process.

[0026] See Figure 1 , Figure 5 A support component 101 is fixedly connected to the bottom surface of the receiving mechanism 1. The main body of the support component 101 is a hollow structure.

[0027] By adopting a hollow structure for the support component 101 at the bottom of the containing mechanism 1, the weight of the mixing tank is reduced, saving material costs.

[0028] See Figure 3 , Figure 4 There are three support components 101, which are fixedly connected to the bottom surface of the receiving mechanism 1 in a ring array.

[0029] By setting three support components 101 arranged in a ring array on the bottom end face of the receiving mechanism 1, the tank body is subjected to uniform force, which improves the stability of the mixing tank.

[0030] See Figure 1 , Figure 2 Each of the three support components 101 has a foot component 102 fixedly connected to its bottom surface. The foot component 102 and the support component 101 together form a support structure for the housing mechanism 1.

[0031] The support structure is formed by the foot assembly 102 and the support assembly 101, which increases the contact area with the ground and disperses the pressure in the tank.

[0032] See Figure 5 , Figure 6 A through hole is provided on the bottom end face of the receiving mechanism 1, and a drain assembly 103 is fixedly connected inside the through hole. The drain assembly 103 has a bidirectional through structure on both the upper and lower sides.

[0033] The drainage component 103 has a bidirectional through-flow structure, which ensures that the solution flows out smoothly, avoids residue, and improves production efficiency.

[0034] See Figure 2 , Figure 4 A valve body assembly 104 is fixedly connected to the outside of the drain assembly 103. The valve body assembly 104 is a solenoid valve structure. The valve body assembly 104 and the drain assembly 103 together form a drain structure.

[0035] The valve body assembly 104 and the drain assembly 103 form a drain structure, and the valve body assembly 104 is a solenoid valve, which can precisely control the opening and closing of the drain.

[0036] See Figure 1 , Figure 2 A base mechanism 3 is mounted on the rear output shaft of servo motor A202. The base mechanism 3 is rotatably connected to the inner side of the support mechanism 2. A servo motor B301 is mounted on the top surface of the base mechanism 3. A mixing component 302 is mounted on the bottom output shaft of servo motor B301. The servo motor B301 and the mixing component 302 together form a mixing structure for the solution.

[0037] By enabling the mixing component 302 to stir and mix the sodium hydroxide solution, the sodium hydroxide is fully mixed with other raw materials, thereby improving the uniformity of the solution and the quality of the product.

[0038] During operation, first, place the mixing tank in the designated position with the support leg assembly 102 in contact with the ground. The support assembly 101 and the support leg assembly 102 together support the containing mechanism 1, ensuring the mixing tank is placed stably. Then, add the raw materials required for producing sodium hydroxide solution into the containing mechanism 1.

[0039] Servo motor A202 is started, and its output shaft drives the base mechanism 3 to rotate around the inner side of the support mechanism 2. During the rotation of the base mechanism 3, servo motor B301 is started, and its bottom output shaft drives the mixing component 302 to rotate. As the mixing component 302 rotates, it stirs the solution within the container 1. Simultaneously, the rotation of the base mechanism 3 causes the mixing component 302 to oscillate during stirring. This oscillating motion allows the solution to flow more evenly within the container 1, preventing the solution from simply rushing towards the inner wall of the container, and ensuring that sodium hydroxide fully contacts and mixes with other raw materials.

[0040] Once the sodium hydroxide solution is mixed, the valve assembly 104 (solenoid valve) is opened. Since the drain assembly 103 has a bidirectional through-structure on both the upper and lower sides, the solution is discharged from the receiving mechanism 1 through the drain assembly 103 under the action of gravity, thus completing the draining operation.

[0041] In summary, this device, by incorporating the valve body assembly 104, can achieve precise control of liquid flow.

[0042] Furthermore, any content not described in detail in this specification is existing technology known to those skilled in the art.
