[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, 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, 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] according to Figure 1 , 2As shown in Figures 3 and 4, this embodiment proposes a material anti-settling storage tank stirring device, including a stirrer applied to the stirring tank 1 and the upper end cover 21. The stirrer includes a first motor group 6, and the output end of the first motor group 6 is fixedly connected to a first stirring component provided in the stirring tank 1. The first mixing element has a second mixing element on its left and right sides. The second mixing element has a turntable 7 on its upper end. The turntable 7 is rotatably mounted in the turntable slot 8 opened at the upper end of the upper cover 21. The upper end of the turntable slot 8 is fixedly mounted with a second motor group 9. The output end of the second motor group 9 is fixedly connected to the second mixing element. The left and right sides of the turntable slot 8 are provided with fixing pins. The fixing pins are inserted into the pin holes opened inside the turntable slot 8 to provide guidance for the rotation of the turntable 7. The turntable slot 8 and the turntable 7 fit tightly. Under the storage requirements of low airtightness, the design should also avoid excessive gaps at the fit, which would reduce the sealing of the upper cover 21 and the mixing box 1.

[0022] The upper end of the upper cover 21 is provided with a side push assembly for pushing the two second motor groups 9 to swing around the turntable 7. The side push assembly is detachably connected to the second motor group 9.

[0023] After the stirring device is started, the first motor unit 6 drives the first stirring component to rotate, which performs basic stirring of the material at the bottom of the mixing tank 1. The second motor unit 9 drives the second stirring component to rotate synchronously, which stirs the material in the middle and upper layers. The three-dimensional layered stirring design can ensure that the material in the upper and lower layers of the mixing tank 1 can be fully stirred, reducing the material settling rate.

[0024] If it is necessary to expand the mixing range, the side push component is activated. The side push component will push the two second motor groups 9. The second motor groups 9 swing around the turntable 7 in the turntable slot 8, thereby driving the second mixing component to swing, changing its mixing angle, realizing dynamic adjustment of the mixing area, eliminating the edge dead corners of traditional fixed mixing, and further improving mixing efficiency.

[0025] The mixing tank 1 is provided with a feeding pipe 2 at the upper end and a discharge pipe 3 at the lower end. The feeding pipe 2 is fixedly installed on the side of the mixing tank 1, and the discharge pipe 3 is fixedly installed at the bottom of the mixing tank 1. The feeding pipe 2 and the discharge pipe 3 are connected to the mixing tank 1.

[0026] The first stirring component includes a first stirring shaft 4, the upper end of which is fixedly connected to the output end of the first motor unit 6, and the lower end of the first stirring shaft 4 is provided with stirring blades A, which are placed at the bottom of the stirring box 1.

[0027] The second stirring component includes a second stirring shaft 5, which is rotatably mounted at the lower end of the turntable 7. The upper end of the second stirring shaft 5 is fixedly connected to the output end of the second motor unit 9. The lower end of the second stirring shaft 5 is provided with stirring blades B, which are positioned above stirring blades A and offset from stirring blades A.

[0028] Materials are fed into the mixing tank 1 through the feeding pipe 2. The first motor unit 6 is started, and the first stirring shaft 4 rotates. The first stirring shaft 4 stirs the materials at the bottom of the mixing tank 1 through the stirring blades A to prevent the materials at the bottom from settling.

[0029] Start the second motor unit 9 to drive the second stirring shaft 5 to rotate. The stirring blade B at the lower end of the second stirring shaft 5 rotates above the stirring blade A to stir the middle and upper layer of materials, forming a three-dimensional stirring zone and improving the uniformity of stirring.

[0030] Regarding the side-pushing component: The side push assembly includes a positioning bracket 10, which is detachably connected to the upper end of the upper cover 21. The positioning bracket 10 has two push blocks 12 on the side facing the second motor group 9. The push blocks 12 are slidably connected to the adjustment groove 11 opened on the outside of the positioning bracket 10. The positioning bracket 10 is provided with an adjustment mechanism for adjusting the distance between the two push blocks 12. The second motor assembly 9 is provided with a first guide block 13 on the side facing the positioning bracket 10. The first guide block 13 is detachably connected to the second motor assembly 9. A second guide block 19 and a movable pin 20 are provided between the push block 12 and the first guide block 13. One end of the movable pin 20 is rotatably connected to the second guide block 19, and the other end of the movable pin 20 is fixedly connected to the push block 12. The second guide block 19 is slidably connected to the limiting groove 18 opened on the outside of the first guide block 13.

[0031] The adjustment mechanism causes the two push blocks 12 to slide along the adjustment groove 11. The push blocks 12 drive the second guide block 19 to slide in the limiting groove 18 of the first guide block 13 through the movable pin 20, thereby pushing the second motor unit 9 to swing in the turntable slot 8 with the turntable 7 as the center, so as to realize the swing adjustment of the second stirring shaft 5 and the stirring blade B.

[0032] More specifically, the adjustment mechanism includes an adjustment motor 14 and a double-ended screw 15. The double-ended screw 15 is rotatably disposed inside the adjustment groove 11, and the adjustment motor 14 is fixedly disposed outside the positioning bracket 10. The output end of the adjustment motor 14 is fixedly connected to the double-ended screw 15, and two push blocks 12 are respectively sleeved on the left and right ends of the double-ended screw 15 and threadedly connected to the double-ended screw 15.

[0033] The regulating motor 14 drives the double-headed screw 15 to rotate. As the double-headed screw 15 rotates, it cooperates with the push block 12, causing the push block 12 to move along the body of the double-headed screw 15. Since the threads at both ends of the double-headed screw 15 are in opposite directions, the two push blocks 12 will move in opposite directions, thereby achieving synchronous control of the two second motor groups 9.

[0034] It is worth explaining in detail that the first guide block 13 has a groove on the side facing the second motor unit 9, and the second motor unit 9 engages with the groove. Multiple fixing bolts are fitted on the outer side of the first guide block 13. The fixing bolts are screwed into the groove and threadedly connected to the bolt holes on the outer side of the second motor unit 9. The first guide block 13 is fixed to the second motor unit 9 by bolt connection.

[0035] It is worth explaining in detail that the positioning bracket 10 has mounting brackets 16 at both ends. The upper end of the mounting bracket 16 is fixedly connected to the positioning bracket 10, and the lower end of the mounting bracket 16 is equipped with multiple mounting bolts 17. The mounting bolts 17 pass through the mounting bracket 16 and are threadedly connected to the bolt holes opened on the upper end of the upper cover 21. The positioning bracket 10 is also fixed to the upper end of the upper cover 21 by bolt connection.

[0036] When maintenance of the side push assembly is required, the mounting bolt 17 on the mounting bracket 16 can be unscrewed to remove the positioning bracket 10, or the first guide block 13 can be removed by the fixing bolt on the outside of the first guide block 13, which facilitates component replacement and maintenance.

[0037] How this application works: Materials are fed into the mixing tank 1 through the feeding pipe 2. The first motor unit 6 is started, and the first stirring shaft 4 rotates. The first stirring shaft 4 stirs the materials at the bottom of the mixing tank 1 through the stirring blades A to prevent the materials at the bottom from settling.

[0038] Start the second motor unit 9 to drive the second stirring shaft 5 to rotate. The stirring blade B at the lower end of the second stirring shaft 5 rotates above the stirring blade A to stir the middle and upper layer of materials, forming a three-dimensional stirring zone and improving the uniformity of stirring.

[0039] Start the regulating motor 14 to drive the double-headed screw 15 to rotate. Since the threads at both ends of the double-headed screw 15 are in opposite directions, the two push blocks 12 slide in opposite directions along the regulating groove 11. The push blocks 12 drive the second guide block 19 to slide in the limiting groove 18 of the first guide block 13 through the movable pin 20, thereby pushing the second motor group 9 to swing around the turntable 7 in the turntable slot 8, realizing the swing adjustment of the second stirring shaft 5 and the stirring blade B, expanding the stirring coverage area, and preventing the material from settling near the inner wall of the mixing tank 1.

[0040] After mixing is completed, all motor units are turned off, and the material is discharged through the discharge pipe 3. When it is necessary to maintain the side push component, the mounting bolt 17 on the mounting bracket 16 can be unscrewed to remove the positioning bracket 10, or the first guide block 13 can be removed through the fixing bolt on the outside of the first guide block 13, which facilitates component replacement and maintenance.
