Description

TECHNICAL FIELD

[0001] The utility model relates to the field of granulator, especially a swing granulator. BACKGROUND

[0002] With the rapid development of chemical industry, pharmaceutical industry, food processing and other industries, the demand for efficient and high-quality granular products is increasing, and using a granulator for mechanical granulation is a common and important means.

[0003] Traditional granulators usually use static or single-direction motion granulation methods, such as raw materials being granulated on a fixed granulation screen, and a scraper cylinder scraping the surface of the granulation screen at a certain speed to cut the raw materials into granules. The existing granulator has the following problems: due to the single relative motion mode between the granulation screen and the scraper cylinder, the cutting force received by the raw materials during the granulation process is limited, resulting in unsatisfactory dispersion and mixing of the raw materials, and it is difficult to form uniform granules, which not only affects the quality and appearance of the product, but also limits the improvement of the granulation efficiency. Secondly, the traditional fixed granulation screen often causes excessive wear in local areas during use due to the continuous scraping of the scraper cylinder. This local wear not only shortens the service life of the granulation screen, but also increases the maintenance cost and downtime of the equipment. At the same time, due to uneven wear, the utilization efficiency of the granulation screen is also greatly reduced, and some areas fail prematurely due to severe wear, while the remaining areas may still be in good condition.

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0026] As Figures 1-3 shown, the utility model provides a swing granulator, including frame 1, one side of frame 1 is fixed with hopper 2, the scraper barrel 3 is rotated in hopper 2, the side wall of hopper 2 is equipped with two symmetrical rotating holes, and the rotating hole is located at both sides above the scraper barrel 3 respectively, and the clamping pipe 4 is rotated in the rotating hole, the lower part of scraper barrel 3 is covered with granulating net 5, and the both ends of granulating net 5 are wound and fixed on clamping pipe 4, and the drive device of driving clamping pipe 4 is arranged in frame 1.

[0027] In use, the raw materials are put into the hopper 2, the scraper cylinder 3 is started, and the driving device is started to rotate the clamping pipes 4, which drive the granulating nets 5 to move tangentially opposite to the rotation direction of the scraper cylinder 3. The tangential movement of the clamping pipes 4 and the scraper cylinder 3 can provide an additional shearing force for the raw materials, which helps the raw materials to be better dispersed, mixed and formed into uniform particles. Compared with the traditional static or single direction movement granulation method, the granulation efficiency is significantly improved. By constantly changing the working position of the granulating nets 5, the entire surface can be evenly worn, thereby improving the utilization efficiency of the net surface. By adjusting the rotation speed of the driving device, the moving speed of the granulating nets 5 can be controlled. When needed, the speed of the granulating nets 5 is reduced, which can reduce the friction and wear between the granulating nets 5 and the raw materials and the scraper cylinder 3, thereby prolonging the service life of the granulating nets 5 and the entire equipment. By controlling the rotation of the two clamping pipes 4 in opposite directions, the granulating nets 5 can be conveniently provided with tension. The problem of inability to granulate or damage caused by loosening of the granulating nets 5 is effectively prevented, and the stability and reliability of the granulation process are enhanced.

[0028] As shown in Figures 1-5 The end of the clamping pipe 4 away from the rack 1 penetrates the hopper 2 through a rotating hole, and the clamping pipe 4 includes a sleeve 6. The side wall of the sleeve 6 is provided with a long hole 7 for the granulating net 5 to pass through. A fixed rod 8 is arranged in the sleeve 6, and a through slot 9 is arranged on the fixed rod 8. The through slot 9 can correspond to the long hole 7. The end of the fixed rod 8 outside the hopper 2 is fixed with a ratchet wheel 10. The end of the sleeve 6 is provided with a sleeve ring 11 capable of accommodating the ratchet wheel 10. The sleeve ring 11 is provided with a check pawl matched with the ratchet wheel 10. The two rotating holes are connected through a dismounting groove 12, and the dismounting groove 12 can pass through the granulating net 5. The outer side wall of the rack 1 is provided with a limiting component for limiting the axial direction of the clamping pipe 4.

[0029] When the over granulating net 5 needs to be disassembled, open the limiting part, align the over granulating net 5 with the disassembly slot 12, and pull out the clamping pipe 4 and the granulating net 5 from between the rotating hole and the disassembly slot 12. When the granulating net 5 needs to be installed, insert the fixed rod 8 into the sleeve 6, and make the through slot 9 correspond to the long hole 7. At this time, the end of the granulating net 5 is inserted into the through slot 9 through the long hole 7, and then the fixed rod 8 is rotated to make the fixed rod 8 rotate to the direction of releasing the ratchet, so that the through slot 9 is staggered with the long hole 7. The outer side wall of the fixed rod 8 and the inner side wall of the sleeve 6 apply friction force to the granulating net 5, realizing the stable fixation of the granulating net 5. After that, the check pawl and the ratchet wheel 10 are automatically clamped, preventing the granulating net 5 from falling off due to excessive external force. After the sleeve 6 and the granulating net 5 are installed in place, the limiting part is closed to prevent the sleeve 6 from falling off. The replacement and maintenance process of the granulating net 5 is simplified, and the work efficiency is improved. By adjusting the position of the fixed rod 8 in the sleeve 6, the tension of the granulating net 5 can be fine-tuned, so that the user can adjust the tightness of the granulating net 5 according to the actual needs, thereby optimizing the granulating effect. When different specifications or types of particles need to be produced, only the corresponding granulating net 5 needs to be replaced, without the need for complex adjustment or modification of the entire device.

[0030] As shown in Figure 2 , 5 , the driving device includes a connecting shaft 13 corresponding to the clamping pipe 4. The connecting shaft 13 is connected with the sleeve 6 through the cooperation of the key and the key groove. One end of one of the connecting shafts 13 is connected with a driving motor 14 in the rack 1. The driving motor 14 drives the other connecting shaft 13 to rotate through the belt pulley. The driving motor 14 is a prior art. The cooperation of the key and the key groove enables the connecting shaft 13 and the sleeve 6 to be quickly connected and facilitates the disassembly of the sleeve 6, shortens the time required for equipment assembly and maintenance, improves the work efficiency, and effectively transmits large torque while maintaining the stability of the connection.

[0031] As shown in Figure 1 , 2 , 6, 7, the sieve plate 15 is connected to the inlet of the hopper 2 through the elastic expansion piece 18. The elastic expansion piece 18 is connected to the four corners of the sieve plate 15 respectively. The clamping pipe 4 and the connecting shaft 13 away from the hopper 2 are fixed with a cam 16. The side wall of the hopper 2 is provided with a through hole 23. The connecting plate 17 is slidably arranged in the through hole 23. The cam 16 drives the elastic expansion piece 18 through the connecting plate 17.

[0032] In the process of discharging, the raw materials will first fall on the sieve plate 15, the cam 16 is driven to rotate by the clamping pipe 4, the cam 16 compresses or stretches the elastic expansion piece 18 through the connecting plate 17, and then drives the sieve plate 15 to move up and down, the up and down movement of the sieve plate 15 will jolt the raw materials, and the large raw materials will be broken in the process of jolting and collide with the sieve plate 15, and the smaller raw materials will directly pass through the sieve plate 15 for granulation. The raw materials have been effectively pretreated before entering the scraper cylinder 3 and the granulation net 5, reducing the labor cost and time of subsequent processing of large raw materials. The up and down movement of the sieve plate 15 can also make the raw materials evenly dispersed, prevent local accumulation of the raw materials, and ensure that the raw materials can enter the scraper cylinder 3 and the granulation net 5 evenly and continuously.

[0033] As shown in Figures 6-8 , the elastic expansion piece 18 includes a movable rod 19 and a fixed plate 20, the fixed plate 20 is fixed on the inner side wall of the hopper 2, the bottom end of the movable rod 19 penetrates the fixed plate 20 and is fixedly connected with the sieve plate 15, a spring is sleeved on the movable rod 19 between the fixed plate 20 and the sieve plate 15, the top end of the movable rod 19 is connected with the connecting plate 17, the other end of the connecting plate 17 abuts against the cam 16, the top surface of the fixed plate 20 is provided with a receiving groove 21, one end of the connecting plate 17 placed in the hopper 2 is provided with a baffle 22, the baffle 22 can cover the through hole 23, and the bottom end of the baffle 22 can be placed in the receiving groove 21. In the use process, the rotation of the cam 16 drives the connecting plate 17 to move up and down, the up and down movement of the connecting plate 17 drives the movable rod 19 to make periodic movement of compressing and releasing the spring, and then the lifting of the sieve plate 15 is realized. By covering most of the through hole 23 through the setting of the baffle 22, the possibility of raw material leakage is reduced, by setting the receiving groove 21, the area of the baffle 22 can be further increased, the effective use of the raw materials in the screening process is ensured, the waste and pollution are reduced, and the receiving groove 21 can play a certain limiting role on the baffle 22.

[0034] As shown in Figure 1 , 7 , the limiting component includes two limiting rods 24, the distance between the limiting rods 24 is greater than the rotating diameter of the cam 16, the limiting rods 24 are both provided with the through hole 23, the through hole 23 is inserted with the clamping pin 25, and the side wall of the clamping pin 25 can abut against the end of the clamping pipe 4. The clamping pin 25 can be a rod-shaped part with one end larger than the through hole 23. When it is needed to disassemble the clamping pipe 4, the clamping pin 25 is pulled out to make the clamping pipe 4 move along the rotating hole, and when it is needed to fix the clamping pipe 4, the clamping pipe 4 is placed in the rotating hole, and then the clamping pin 25 is placed in the through hole 23 of the two limiting rods 24. The insertion and pulling out operation of the clamping pin 25 is very simple, without the need of complicated tools or skills. The disassembly and installation of the clamping pipe 4 become very fast, and the work efficiency is greatly improved.
