Description

Technical Field

[0001] This utility model relates to the field of thickener technology, specifically to a stirring and feeding mechanism for a center-driven thickener. Background Technology

[0002] A center-driven thickener is a device used for concentrating and recovering liquids. Its working principle involves a central drive mechanism that rotates the liquid within a container uniformly. Simultaneously, heating and vacuum extraction separate volatile components such as solvents and water, thus concentrating the liquid. The thickener is equipped with a stirring and feeding mechanism, driven by a central drive shaft. This mechanism ensures uniform mixing of the material within the thickener, preventing sedimentation and clumping, and improving concentration efficiency.

[0003] A search revealed that patent CN218130160U discloses a spiral stirring and feeding structure for a center-driven thickener. In this patent, the upper end of the spiral blades is connected to the center drive shaft via an upper connector, and the lower end of the spiral blades is connected to the center drive shaft via a lower connector. The spiral surface of the spiral blades has a large contact area with the material, which can ensure that viscous materials are evenly turned upwards. When the spiral blades rotate, they will rub against the viscous material. This continuous friction will gradually wear down the surface of the spiral blades. The spiral blades are connected to the center drive shaft by welding. These connection methods require specific tools for disassembly, and the operation process is relatively cumbersome, increasing the difficulty of installation and disassembly. In view of this, a stirring and feeding mechanism for a center-driven thickener was designed. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a stirring and feeding mechanism for a center-driven thickener, which solves the problem that when the spiral blades rotate, they will rub against the viscous material, and this continuous friction will gradually wear down the surface of the spiral blades. Furthermore, the installation and replacement of existing spiral blades are cumbersome and time-consuming.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a stirring and feeding mechanism for a center-driven thickener, comprising a feeding hopper and a stirring shaft, wherein the feeding hopper is fixedly connected to the opening of the thickener, and the stirring shaft is fixedly connected to the drive assembly of the thickener, and the bottom of the stirring shaft extends into the interior of the feeding hopper;

[0006] The outer surface of the stirring shaft is fitted with a first fixing sleeve. A square frame is fixedly connected to both sides of the first fixing sleeve. A support rod is connected to the square frame. A second fixing sleeve is movably fitted to one end of the support rod. A stirring blade is fixedly connected to the second fixing sleeve. The second fixing sleeve is fixedly connected to the support rod by a second fixing bolt.

[0007] Furthermore, there are two first fixing sleeves, which are arranged symmetrically one above the other.

[0008] Furthermore, the outer surface of the first fixing sleeve is threaded with a first fixing bolt, one end of which extends into the interior of the first fixing sleeve and abuts against the outer surface of the stirring shaft.

[0009] Furthermore, the stirring blade is spirally shaped, and both ends of the stirring blade are fixedly connected to two second fixed sleeves.

[0010] Furthermore, the second fixing sleeve has a through hole, one end of the support rod has a threaded hole, the second fixing bolt is movably inserted into the through hole, and the bottom end of the second fixing bolt is threaded into the threaded hole.

[0011] Furthermore, an insertion hole is provided in the middle of the side of the square frame, and the end of the support rod away from the second fixing sleeve is inserted into the insertion hole.

[0012] Furthermore, the end of the support rod away from the second fixing sleeve is respectively threaded with a first fixing nut and a second fixing nut, the first fixing nut abutting against the inner side of the square frame, and the second fixing nut abutting against the outer side of the square frame.

[0013] By means of the above technical solution, this utility model provides a stirring and feeding mechanism for a center-driven thickener, which has at least the following beneficial effects:

[0014] 1. When the stirring and feeding mechanism of the central drive thickener needs to replace or install the stirring blades, the support rod can be removed from the square frame, the second fixing bolt can be loosened, and the second fixing sleeve can be easily removed from the support rod, which facilitates the replacement or maintenance of the stirring blades. The operation is simple, reduces maintenance costs and time, and improves the maintenance efficiency and ease of use of the equipment.

[0015] 2. The stirring and feeding mechanism of this centrally driven thickener has a support rod inserted into the insertion hole. The double fixing with a first and second fixing nut enhances the connection strength between the support rod and the square frame, preventing loosening or detachment during stirring. When it is necessary to replace or repair the stirring blades and support rod, simply loosen the first and second fixing nuts to easily remove the support rod from the square frame.

[0024] 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.

[0025] Please see Figure 1-6 A stirring and feeding mechanism for a center-driven thickener includes a feeding hopper 1 and a stirring shaft 2. The feeding hopper 1 is fixedly connected to the opening of the thickener, and the stirring shaft 2 is fixedly connected to the drive assembly of the thickener. The bottom of the stirring shaft 2 extends into the interior of the feeding hopper 1.

[0026] Two first fixing sleeves 3 are fitted onto the outer surface of the stirring shaft 2, arranged symmetrically vertically. A square frame 5 is fixedly connected to both sides of each first fixing sleeve 3. A support rod 6 is connected to the square frame 5, and a second fixing sleeve 8 is movably fitted onto one end of the support rod 6. A stirring blade 7 is fixedly connected to the second fixing sleeve 8, which is secured to the support rod 6 by a second fixing bolt 9. When it is necessary to replace or install the stirring blade 7, the support rod 6 can be removed from the square frame 5, and the second fixing bolt 9 can be loosened to easily remove the second fixing sleeve 8 from the support rod 6. This facilitates the replacement or maintenance of the stirring blade 7, simplifying the operation, reducing maintenance costs and time, and improving the maintenance efficiency and ease of use of the equipment.

[0027] The outer surface of the first fixing sleeve 3 is threaded with a first fixing bolt 4. One end of the first fixing bolt 4 extends into the interior of the first fixing sleeve 3, and the other end abuts against the outer surface of the stirring shaft 2. The first fixing bolt 4 facilitates the fixation of the first fixing sleeve 3. When it is necessary to replace or repair the support rod 6 or the stirring blade 7, simply loosen the first fixing bolt 4 to easily remove the first fixing sleeve 3 from the stirring shaft 2, making the maintenance process simple and convenient, and reducing maintenance costs and time.

[0028] The stirring blade 7 is arranged in a spiral shape, and its two ends are fixedly connected to two second fixed sleeves 8. During the rotation of the spiral stirring blade 7, it can generate a stronger stirring force, so that the material is subjected to continuous pushing and shearing action during the stirring process, which is conducive to the uniform mixing and refinement of the material. Moreover, the rotation trajectory of the spiral stirring blade 7 covers multiple layers in the feed hopper 1, so that the material can be fully stirred in all directions, improving the mixing uniformity.

[0029] The second fixing sleeve 8 has a through hole, and one end of the support rod 6 has a threaded hole. The second fixing bolt 9 is movably inserted into the through hole, and the bottom end of the second fixing bolt 9 is threaded into the threaded hole. The second fixing bolt 9 securely fixes the second fixing sleeve 8 to the support rod 6 through a threaded connection, preventing the stirring blade 7 from loosening or falling off during high-speed rotation, thus ensuring stable operation of the equipment. Rotating the second fixing bolt 9 allows for quick and easy fixing of the second fixing sleeve 8 to or removal from the support rod 6, simplifying and accelerating the replacement and maintenance of the stirring blade 7, reducing maintenance costs and time.

[0030] An insertion hole is provided in the middle of the side of the square frame 5, and the end of the support rod 6 away from the second fixing sleeve 8 is inserted into the insertion hole. A first fixing nut 10 and a second fixing nut 11 are threaded onto the end of the support rod 6 away from the second fixing sleeve 8, respectively. The first fixing nut 10 abuts against the inner side of the square frame 5, and the second fixing nut 11 abuts against the outer side of the square frame 5. The double fixing of the support rod 6 in the insertion hole, along with the first fixing nut 10 and the second fixing nut 11, enhances the connection strength between the support rod 6 and the square frame 5, preventing loosening or detachment during the stirring process. When it is necessary to replace or repair the stirring blade 7 and the support rod 6, simply loosen the first fixing nut 10 and the second fixing nut 11 to easily remove the support rod 6 from the square frame 5.

[0031] Working principle: When the drive assembly of the transmission thickener is started, the stirring shaft 2 begins to rotate. Due to the fixed connection between the first fixed sleeve 3 and the square frame 5, the rotation of the stirring shaft 2 will drive the square frame 5 and the support rod 6 to rotate together. The stirring blade 7 is movably sleeved on the support rod 6 through the second fixed sleeve 8 and fixed by the second fixing bolt 9. When the support rod 6 rotates, the stirring blade 7 will also rotate, thereby stirring and conveying the material in the feed hopper 1, preventing the material from settling and clumping, and improving the concentration efficiency.

[0032] When it is necessary to replace or install the mixing blade 7, simply loosen the first fixing nut 10 and the second fixing nut 11, remove the support rod 6 from the square frame 5, loosen the second fixing bolt 9, and the second fixing sleeve 8 can be easily removed from the support rod 6, which facilitates the replacement or maintenance of the mixing blade 7. The operation is simple, reduces maintenance costs and time, and improves the maintenance efficiency and ease of use of the equipment.
