Description

Technical Field

[0001] The utility model relates to the technical field of stirring, mixing and drying machines, in particular to a horizontal spiral ribbon stirring and mixing drying machine. Background Technique

[0002] In industries such as chemical industry, medicine, and food, operations such as stirring and drying are often required. Such operations need to be realized by applying process equipment such as mixers and dryers respectively. To improve the stirring and mixing efficiency, a horizontal spiral ribbon stirring and mixing drying machine has emerged on the market.

[0003] According to a high-efficiency horizontal spiral ribbon stirring and mixing drying machine disclosed on the patent network (authorization announcement number: CN209027220U), it is described that "the utility model discloses a high-efficiency horizontal spiral ribbon stirring and mixing drying machine. An inner spiral ribbon and an outer spiral ribbon structure that tilt towards the center of the cylinder or both sides of the cylinder are arranged on the central shaft inside the cylinder. When the central shaft drives the inner spiral ribbon and the outer spiral ribbon to rotate, the tendency of the inner spiral ribbon to drive the material to move and the tendency of the outer spiral ribbon to drive the material to move are opposite, forming a reciprocating movement effect of the material, so that the material is fully stirred; the hollow central shaft, support rod, inner spiral ribbon, and outer spiral ribbon inside the cylinder, as well as the jacket structure outside the cylinder, can all be passed through a heat medium to heat the cylinder, so as to achieve the effect of evaporative drying of the material inside the cylinder. The high-efficiency horizontal spiral ribbon stirring and mixing drying machine of the utility model has good stirring and drying effects, and can perform the functions of stirring and drying separately or synchronously on one device, improving the production efficiency".

[0004] In view of the above description, the applicant believes that there are the following problems:

[0005] During the use of this utility model, although an inner spiral ribbon and an outer spiral ribbon structure that tilt towards the center of the cylinder or both sides of the cylinder can be arranged on the central shaft inside the cylinder, when the central shaft drives the inner spiral ribbon and the outer spiral ribbon to rotate, the tendency of the inner spiral ribbon to drive the material to move and the tendency of the outer spiral ribbon to drive the material to move are opposite, forming a reciprocating movement effect of the material, so that the material is fully stirred. However, in actual application, when feeding the material, if there are many agglomerated masses in the material, it will lead to a poor stirring and mixing effect in the later stage, and a large amount of material is likely to adhere to the inner wall of the cylinder, easily causing material waste. In addition, since the discharge port diameter of this device is relatively fixed, it is difficult to dynamically adjust the discharge speed according to different working requirements. Therefore, we urgently need to improve a horizontal spiral ribbon stirring and mixing drying machine to solve the above problems. Content of the Utility Model

A connection frame 56 is fixedly installed outside the discharge pipe 51. A plug-in block 57 is slidably installed inside the connection frame 56. A second spring 58 is arranged inside the connection frame 56. A regulating pull ring 59 is fixedly installed outside the plug-in block 57, which is convenient for dynamically adjusting the discharge speed according to different working requirements.

[0036] Furthermore, the installation column 53 is rotatably installed with the discharge pipe 51. The plug-in block 57 meshes with the installation column 53.

[0037] During the actual operation process, when this device is used, first, the material to be processed can be added from the top of the feed hopper 412. To avoid the phenomenon of more agglomerated lumps or larger particles in the material, the driving motor 413 can be turned on to make the first crushing roller 414 rotate, so that the connecting gear 416 arranged on the front surface of the first crushing roller 414 rotates, thereby making the connecting gear 416 on the front surface of the second crushing roller 415 rotate, so that the set second crushing roller 415 rotates in the reverse direction.

Subsequently, the driving device 32 is operated. Under the action of the spiral ribbon stirring shaft 33, the material inside the mixing outer cylinder 31 can be fully stirred and mixed to improve the drying effect. At the same time, when the spiral ribbon stirring shaft 33 rotates, the set connecting frame 421 will rotate accordingly. Under the action of the arc-shaped scraper 425, the material adhering to the inner wall of the mixing outer cylinder 31 can be scraped off. Under the action of the first spring 424, the set arc-shaped scraper 425 can always be in contact with the inner wall of the mixing outer cylinder 31 to ensure the scraping effect.

Subsequently, the handle 54 is rotated. Under the action of the installation column 53, the angle of the set regulating plate 52 can be dynamically adjusted, thereby changing the discharge rate. After the adjustment is completed, the regulating pull ring 59 can be released. Under the action of the second spring 58, the plug-in block 57 returns to its initial position, so that the plug-in block 57 resumes the plugging and meshing state with the toothed block disk 55 to fix the angle of the regulating plate 52 and complete the relevant discharge work.
