Description

Technical Field

[0001] The utility model relates to the technical field of stirring tools, in particular to a bidirectional spiral stirring structure. Background Art

[0002] A stirring structure refers to a mechanical device used to mix, stir, homogenize or disperse different substances in various containers or reactors. It is usually composed of one or more rotating parts. These parts rotate under power drive to diffuse the materials to achieve the purpose of uniform mixing. However, the existing stirring structure has the following defects:

[0003] Traditional stirring rods or agitators are usually designed to stir in a single direction, that is, the rotation direction of multiple rotating parts is consistent, resulting in poor mixing uniformity, especially when dealing with high-viscosity or difficult-to-mix materials. Therefore, in order to achieve the required uniformity, longer stirring time is required to compensate, which will increase the production cycle and reduce production efficiency.

[0004] Therefore, in order to solve the defect of the single stirring direction of the traditional stirring rod, it is necessary to propose a bidirectional spiral stirring structure. Utility Model Content

[0005] The purpose of the utility model is to provide a bidirectional spiral stirring structure, which can drive the spiral blades at the upper and lower ends to rotate in the opposite direction through the reverse rotation of the stirring rod and the rod sleeve, so that the upper end material moves downward and the lower end material moves upward, and is fully mixed in the middle part of the stirring barrel, thereby improving the uniformity of mixing and solving the problems raised in the above-mentioned background technology.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A bidirectional spiral stirring structure comprises a stirring barrel and a stirring structure, wherein a motor is mounted on the upper end of the stirring barrel through a mounting plate, a driving shaft is fixedly connected to the output end of the motor, and a first pulley and a first gear are fixedly sleeved on the driving shaft;

[0008] The stirring structure includes a stirring rod and a rod sleeve movably installed outside the stirring rod, the stirring rod and the rod sleeve are both connected to spiral blades through a fixed rod, the bottom ends of the stirring rod and the rod sleeve are both symmetrically connected to scraping rods, and the side ends of the scraping rods are provided with scraping blocks.

[0009] Preferably, the bottom end of the stirring rod is movably connected to the inner wall of the stirring barrel, the top end of the stirring rod passes through the stirring barrel and is movably connected to the mounting plate, and the end of the stirring rod located outside the stirring barrel is fixedly sleeved with a second pulley, and the second pulley is connected to the first pulley through a transmission belt.

[0010] Preferably, the top end of the rod sleeve passes through the mixing barrel and is located outside the mixing barrel, the top end of the rod sleeve is movably connected to the mixing barrel, and one end of the rod sleeve located outside the mixing barrel is fixedly sleeved with a second gear, and the second gear is meshed with the first gear.

[0011] Preferably, the number of the spiral blades outside the stirring rod or the rod sleeve is two, and they are arranged in a ring array with respect to the stirring rod or the rod sleeve.

[0012] Preferably, the cross-section of the scraper block is triangular.

[0013] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0014] 1. The bidirectional spiral stirring structure starts the motor to drive the driving shaft to rotate clockwise. Under the drive of the first pulley, the second pulley and the transmission belt, the stirring rod can rotate clockwise. Under the drive of the first gear and the second gear, the rod sleeve can rotate counterclockwise to achieve bidirectional rotation of the spiral blades. The stirring structure can generate mixing force in two directions, which is helpful to break the lumps of materials, improve the uniformity of material stirring, and improve production efficiency.

[0015] 2. This bidirectional spiral stirring structure can scrape off the material adhering to the inner wall of the mixing barrel through the scraping rod and the scraping block, preventing the material from agglomerating or adhering to the container wall, simplifying the subsequent cleaning work, and reducing the residue of the material on the container wall, thereby reducing the waste of the material.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] To solve the technical problem of how to reverse the rotation of the stirring rod and the rod sleeve, please refer to Figure 1-Figure 3 , this embodiment provides the following technical solutions:

[0022] A bidirectional spiral stirring structure comprises a stirring barrel 1 and a stirring structure 2. A motor 13 is mounted on the upper end of the stirring barrel 1 via a mounting plate 11. A driving shaft 12 is fixedly connected to the output end of the motor 13. A first pulley 14 and a first gear 16 are fixedly sleeved on the driving shaft 12.

[0023] The stirring structure 2 includes a stirring rod 21 and a rod sleeve 22 movably installed outside the stirring rod 21. The bottom end of the stirring rod 21 is movably connected to the inner wall of the stirring barrel 1. The top end of the stirring rod 21 penetrates the stirring barrel 1 and is movably connected to the mounting plate 11. One end of the stirring rod 21 located outside the stirring barrel 1 is fixedly sleeved with a second pulley 211, and the second pulley 211 is connected to the first pulley 14 through a transmission belt 15.

[0024] The top end of the rod sleeve 22 passes through the mixing barrel 1 and is located outside the mixing barrel 1 . The top end of the rod sleeve 22 is movably connected to the mixing barrel 1 . The end of the rod sleeve 22 located outside the mixing barrel 1 is fixedly sleeved with a second gear 221 , which meshes with the first gear 16 .

[0025] Specifically, the motor 13 is started, and the motor 13 drives the drive shaft 12 fixedly connected thereto to rotate clockwise, and the drive shaft 12 then drives the first pulley 14 and the first gear 16 fixedly connected thereto to rotate clockwise, and under the transmission of the transmission belt 15, the second pulley 211 drives the stirring rod 21 fixedly connected thereto to rotate clockwise, and under the engagement of the second gear 221, the rod sleeve 22 rotates counterclockwise, thereby realizing the reverse rotation movement of the rod sleeve 22 and the stirring rod 21.

[0026] To solve the technical problem of how the stirring structure can improve the stirring uniformity, please refer to Figure 2 , this embodiment provides the following technical solutions:

[0027] The stirring rod 21 and the rod sleeve 22 are both connected with spiral blades 24 through a fixing rod 23 . There are two spiral blades 24 on the stirring rod 21 or the rod sleeve 22 , and they are arranged in a ring array with respect to the stirring rod 21 or the rod sleeve 22 .

[0028] The spiral blade 24 on the outer wall of the stirring rod 21 is disposed at the lower end, and the length of the stirring rod 21 is greater than twice the length of the rod sleeve 22 .

[0029] Specifically, since the stirring rod 21 and the rod sleeve 22 rotate in the opposite direction, the spiral blades 24 at the upper and lower ends can be driven to rotate in the opposite direction, so that the stirring structure 2 can generate mixing forces in two directions, thereby improving the efficiency of material mixing and shortening the stirring time. At the same time, the upper material moves downward and the lower material moves upward, and is fully mixed in the middle part of the stirring barrel, thereby improving the uniformity of stirring.

[0030] To solve the technical problem of how the stirring structure can achieve wall scraping, please refer to Figure 2 , this embodiment provides the following technical solutions:

[0031] The bottom ends of the stirring rod 21 and the rod sleeve 22 are both symmetrically connected with a scraping rod 25 , and the side ends of the scraping rod 25 are provided with a scraping block 26 , and the cross section of the scraping block 26 is arranged in a triangular shape.

[0032] The side end of the scraper block 26 is tightly fitted to the inner wall of the mixing barrel 1 .

[0033] Specifically, when the stirring rod 21 rotates, it drives the scraper rod 25 to rotate along the inner wall of the stirring barrel 1, so that the scraper block 26 scrapes off the material stuck to the inner wall of the stirring barrel 1, reducing the waste of material and alleviating the difficulty of subsequent cleaning.

[0034] Working principle: When the bidirectional spiral stirring structure is in use, the motor 13 is started, and the motor 13 drives the driving shaft 12 to rotate clockwise, and the driving shaft 12 then drives the first pulley 14 and the first gear 16 fixed thereto to rotate clockwise. Under the transmission of the transmission belt 15, the second pulley 211 drives the stirring rod 21 fixed thereto to rotate clockwise, and under the engagement of the second gear 221, the rod sleeve 22 rotates counterclockwise, so that the rod sleeve 22 and the stirring rod 21 can drive the spiral blades 24 at the upper and lower ends to perform bidirectional rotational motion, providing mixing forces in different directions, improving mixing efficiency, shortening mixing time, and at the same time, the upper end material moves downward and the lower end material moves upward, and is fully mixed in the middle part of the stirring barrel, thereby improving the uniformity of stirring.
