Technical Field
[0001] This utility model relates to the field of fluid mixing and quantitative delivery technology, and in particular to a double-helix brine preparation device. Background Technology
[0002] In industries such as chemical engineering, food processing, and printing and dyeing, the preparation of brine solutions is a crucial step in the production process. Traditional brine preparation often relies on manual weighing and stirring, which is not only inefficient but also makes it difficult to ensure the accuracy of the proportions, leading to unstable product quality. With the development of automation technology, some companies have begun to adopt automated brine and water preparation equipment. However, existing equipment still has many problems. On the one hand, existing mixing devices mostly use single-spiral or simple stirring structures, resulting in insufficient uniformity of material mixing and easy occurrence of local concentration differences, which affects the effect of subsequent production processes. On the other hand, in the quantitative conveying stage, the feeding control is not precise enough and lacks real-time feedback and adjustment mechanisms, making it difficult to meet the high-precision requirements of brine concentration and delivery volume under different production scenarios. At the same time, the stability and durability of the equipment also need to be improved. Therefore, it is necessary to design a double-spiral brine preparation device to solve the above problems.

[0025] Please see Figure 1-5 This utility model provides a technical solution:
[0026] A double-helix brine preparation device includes a support plate 1, a mixing mechanism 3 fixedly connected to the upper end of the support plate 1, a feeding mechanism 2 fixedly connected to the lower front part of the mixing mechanism 3, a rear plate 6 fixedly connected to the rear end of the mixing mechanism 3, the mixing mechanism 3 fixedly connected to the rear end of the rear plate 6, four support rods 5 fixedly connected to the upper rear part of the mixing mechanism 3, and a fixing frame 4 fixedly connected to the upper end of the support rods 5.
[0027] In this embodiment, the feeding mechanism 2 includes a feeding plate 21 and a first drive motor 25. A first connecting seat 23 is fixedly connected to the middle of the front end of the feeding plate 21. A first control panel 24 is provided on the right side of the front end of the feeding plate 21. An opening and closing assembly 22 is movably installed inside the first connecting seat 23 via a rotating shaft. Side seats 28 are fixedly connected to the lower left and lower right ends of the feeding plate 21. The output end of the first drive motor 25 passes through the feeding plate 21 and is fixedly connected to a rotating rod 26. Multiple distributing plates 27 are fixedly connected to the outer surface of the rotating rod 26. The first drive motor 25 is fixedly connected to the upper right end of the feeding plate 21. The opening and closing assembly 22 includes a cylinder 221. A fisheye connector 222 is fixedly connected to the output end of the cylinder 221. The fisheye connector 222 passes through... A second connecting seat 223 is movably connected via a pivot. The other end of the second connecting seat 223 is fixedly connected to an opening and closing plate 224. Support frames 225 are fixedly connected to the upper left and upper right parts of the opening and closing plate 224. The upper outer part of the support frame 225 is movably installed with the side seat 28 via a pivot. The left and right ends of the cylinder 221 are movably installed with the first connecting seat 23 via a pivot. The opening and closing plate 224 is an arc-shaped plate structure and its curvature matches the outline of the lower opening of the feed plate 21. Two support frames 225 are symmetrically distributed on the left and right sides of the opening and closing plate 224, and the two support frames 225 have an inverted V-shaped structure. Multiple distribution plates 27 are distributed in a ring at equal intervals around the pivot rod 26, and none of the multiple distribution plates 27 are connected to the inner wall of the feed plate 21.
[0028] Through the above scheme: When the feeding mechanism 2 is working, the material output by the mixing mechanism 3 falls into the feeding plate 21. The first drive motor 25 drives the rotating rod 26 to rotate the annularly distributed distribution plates 27, which uniformly convey the material outward. The first control panel 24 can accurately set the feeding amount according to production needs. When it is necessary to control the feeding speed or pause feeding, the cylinder 221 drives the opening and closing plate 224 to rotate around the support frame 225 through the fisheye joint 222 and the second connecting seat 223. By utilizing the arc structure that matches the lower opening of the opening and closing plate 224 with the lower opening of the feeding plate 21, the precise opening and closing control of the feeding port is realized. Since the distribution plate 27 does not contact the inner wall of the feeding plate 21, material residue and wear are avoided, and the service life of the equipment is extended. The inverted V-shaped support frame 225 structure enhances the stability of the opening and closing plate 224, ensuring that the feeding process is smooth and controllable. The overall mechanism significantly improves the feeding accuracy and efficiency through the optimized cooperation of control and mechanical structure, and is suitable for the precise weighing and quantitative compounding needs of the double spiral multi-functional salt and water mixing machine.
[0029] In this embodiment, the mixing mechanism 3 includes a connecting box 37 and a second drive motor 38. The output end of the second drive motor 38 passes through the rear plate 6 and is fixedly connected to a main gear 39. A secondary gear 310 is meshed with the left side of the outer surface of the main gear 39. A connecting shaft 311 is fixedly connected to the middle of the rear end of the secondary gear 310. A second spiral conveying component 313 and a first spiral conveying component 312 are fixedly connected to the front end of the secondary gear 310 and the front end of the main gear 39, respectively. A conveying pipe 36 is respectively inserted into the upper left and upper right parts of the connecting box 37. A discharge pipe 34 is fixedly connected to the other end of the conveying pipe 36. A control valve 35 is provided on the outer surface of the discharge pipe 34. A first material conical barrel 31 and a second material conical barrel 32 are fixedly connected to the other end of the discharge pipe 34, respectively. A second control panel 33 is provided on the rear part of the outer surface of both the first material conical barrel 31 and the second material conical barrel 32. The connecting box 37 is fixedly connected to... At the upper end of the feeding plate 21, the second drive motor 38 is fixedly connected to the rear right side of the rear plate 6. The main gear 39 and the secondary gear 310 are arranged horizontally side by side, and the meshing surface of the main gear 39 and the secondary gear 310 is located in the middle of the rear end of the connecting box 37. The first spiral conveying component 312 and the second spiral conveying component 313 pass through the interior of the connecting box 37 in parallel, and the rotation axis of the first spiral conveying component 312 and the second spiral conveying component 313 coincides with the central axis of the main gear 39 and the secondary gear 310. The first material conical barrel 31 and the second material conical barrel 32 are respectively inserted and connected to the upper left and upper right sides of the fixed frame 4. The first material conical barrel 31 and the second material conical barrel 32 are inverted cone shape. The first material conical barrel 31 and the second material conical barrel 32 are respectively connected to the interior of the connecting box 37 through the feeding pipe 34 and the conveying pipe 36, and the control valve 35 line on the feeding pipe 34 is connected to the external control unit.
[0030] Through the above scheme: When the mixing mechanism 3 is working, materials such as salt and water are placed in the first material cone 31 and the second material cone 32, which are inverted cones and interlocked on the fixed frame 4. The feeding amount is set through the second control panel 33 on the rear of its outer surface. The external control unit controls the control valve 35 on the feeding pipe 34 to open. The material enters the connecting box 37 through the conveying pipe 36. At this time, the second drive motor 38 starts, and its output end passes through the rear plate 6 to drive the main gear 39 to rotate. The main gear 39 meshes with the secondary gear 310. Because the main gear 39 and the secondary gear 310 are arranged horizontally side by side and the meshing surface is located in the middle of the rear end of the connecting box 37, the first spiral conveying component 312 and the second spiral conveying component 313, which are respectively fixed to the front ends of the two, rotate. The first spiral conveyor component 312 and the second spiral conveyor component 313 run parallel through the interior of the connecting box 37, and their rotation axes coincide with the central axes of the main gear 39 and the secondary gear 310. This allows for efficient and thorough mixing of the materials entering the connecting box 37. The mixed materials then fall onto the discharge plate 21 below. Through the symmetrical layout of the double spiral conveyor components and the gear transmission structure, uniform stirring and propulsion of the materials within the connecting box 37 are achieved, improving mixing efficiency and uniformity. The inverted conical material cone facilitates the smooth discharge of materials by gravity. Combined with the control valve 35 and the second control panel 33, the material input can be precisely controlled, meeting the functional requirements of the double spiral multi-functional salt and water dispensing machine for numerical control, sensing, weighing, and quantitative compounding, and ensuring high precision and stability of brine preparation.
[0031] It should be noted that this utility model is a double-spiral brine mixing device. When this double-spiral multi-functional brine mixing machine is working, salt and water are placed in the first material conical drum 31 and the second material conical drum 32, respectively. The second control panel 33 on the rear of its outer surface uses a Siemens SIMATIC S7-1200 series PLC, paired with a TP700 Comfort touchscreen. This combination can work with a high-precision weighing sensor to achieve real-time monitoring and accurate measurement of the weight of the materials in the drums. The target mixing ratio is set through the second control panel 33, and the control valve 35 on the feed pipe 34 is opened. The material enters the connecting box 37 through the conveying pipe 36. The second drive motor 38 starts, driving the main gear 39 to rotate. Through meshing with the secondary gear 310, it drives the first spiral conveying component 312 and the second spiral conveying component 313 to rotate. The material is thoroughly mixed in the connecting box 37, and the mixed material falls into the feeding plate 21 of the feeding mechanism 2. The first control panel 24 adopts an Omron NJ series controller, combined with an NS series human-machine interface, which can receive the weighing sensor signal installed below the feeding plate 21 to realize real-time feedback and precise control of the output weight. The first drive motor 25 drives the rotating rod 26 to rotate the distributing plate 27, which evenly conveys the material outward. When it is necessary to control the feeding speed or stop feeding, the cylinder 221 drives the opening and closing plate 224 to rotate around the support frame 225 through the fisheye joint 222 and the second connecting seat 223. The arc structure of the opening and closing plate 224 and the lower opening of the feeding plate 21 are matched to realize the precise opening and closing control of the feeding port. The entire process is achieved by real-time monitoring of the material weight and feeding amount through the CNC sensing system, realizing the function of weighing and quantitative compounding.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
