Description

Technical Field

[0001] The utility model relates to the technical field of spray granulation equipment, in particular to continuous spray granulation equipment for industrial slurry. Background Art

[0002] In many industrial production processes, it is often necessary to convert liquid or semi-solid materials into granular materials for storage, transportation and further processing. Among them, spray granulation is a common material conversion method, which disperses liquid materials into fine droplets through a high-speed rotating atomizer, and then quickly dries the droplets through hot air or other drying media to form solid particles.

[0003] Traditional spray granulation equipment usually adopts batch operation, that is, first add the liquid material into the sprayer, then atomize and dry it, and finally collect the particles. Although this method is simple and easy to operate, it has some disadvantages, such as the lack of corresponding stirring structure, insufficient mixing of liquid or semi-solid materials, which seriously affects the granulation effect.

[0004] Therefore, a continuous spray granulation equipment for industrial slurry is proposed. Utility Model Content

[0005] The utility model aims to provide a continuous spray granulation device for industrial slurry.

[0008] Spray granulator;

[0009] A discharge pipe is installed on the right outer wall of the spray granulator;

[0010] The top of the spray granulator is symmetrically connected to two support bars, a mixing box is fixed on the top of the two support bars, a feed pipe is installed on the top of the mixing box, an outlet pipe is installed at the bottom of the mixing box, and a valve body is installed on the outer wall of the outlet pipe;

[0011] An inlet pipe is installed on the top of the spray granulator;

[0012] The outlet pipe is plugged into the inside of the inlet pipe;

[0013] A motor is installed on the top of the mixing box, a driving rod penetrating the top of the mixing box and extending into the inside of the mixing box is fixed to the output end of the motor, and a first gear is fixed to the bottom of the driving rod;

[0014] The first gear is meshed with two second gears;

[0015] A first connecting rod is fixed at the bottom of each of the two second gears, and a stirring bar is fixed on the outer wall of the first connecting rod;

[0016] A second connecting rod is fixed to the top of the two second gears, and the top of the second connecting rod is rotatably connected to the inner top of the mixing box.

[0017] Preferably, the diameter of the first gear is greater than the diameter of the second gear.

[0018] Preferably, an external thread is provided on the outer wall of the outlet pipe, and a sealing ring is threadedly connected to the external thread of the outlet pipe.

[0019] Preferably, the bottom of the sealing ring abuts against the top of the inlet pipe.

[0020] Preferably, two installation grooves are symmetrically provided on the top of the spray granulator, and the two support bars are respectively placed inside the two installation grooves.

[0021] Preferably, a threaded hole connected to the mounting groove is provided on the outer wall of the spray granulator;

[0022] A threaded rod is threadedly connected to the threaded hole;

[0023] A rotating shaft is fixed to one end of the threaded rod, and a fixing plate abutting against the supporting bar is fixed to the other end of the threaded rod.

[0024] Compared with the prior art, the beneficial effects of the utility model are:

[0025] The utility model pours liquid or semi-solid materials into a mixing box through a feed pipe, and then starts a motor, which drives a first gear to rotate through a driving rod, and the first gear drives two groups of stirring bars through two second gears to stir the liquid or semi-solid materials, so that the liquid or semi-solid materials are fully mixed, thereby greatly improving the mixing efficiency of the liquid or semi-solid materials and thus improving the granulation effect;

[0026] And because the diameter of the first gear is larger than that of the second gear, under the same motor output efficiency, the rotation speed of the second gear is greater than that of the first gear, thereby increasing the rotation speed of the stirring bar, further increasing the mixing efficiency of the liquid or semi-solid material, and thus improving the granulation effect.

[0027] The utility model rotates the rotating shaft, which drives the threaded rod to move in the threaded hole. When the threaded rod moves, the fixed plate is driven to move accordingly. After the fixed plate is no longer in contact with the support strip, the mixing box can be disassembled. Therefore, the utility model facilitates the disassembly and separation of the mixing box and the spray granulator, thereby facilitating the cleaning and maintenance of the mixing box and the spray granulator.

[0037] Specifically, the utility model pours the liquid or semi-solid material into the mixing box 4 through the feed pipe 5, and then starts the motor 9, the motor 9 drives the first gear 11 to rotate through the driving rod 10, and the first gear 11 drives the two sets of stirring bars 15 through the two second gears 12 to stir the liquid or semi-solid material, so that it is fully mixed, which greatly improves the mixing efficiency of the liquid or semi-solid material, and then improves the granulation effect;

[0038] And because the diameter of the first gear 11 is greater than the diameter of the second gear 12, under the same output efficiency of the motor 9, the rotation speed of the second gear 12 is greater than the rotation speed of the first gear 11, thereby increasing the rotation speed of the stirring bar 15, further increasing the mixing efficiency of the liquid or semi-solid material, and thus improving the granulation effect;

[0039] And by rotating the sealing ring 17, one end of the sealing ring 17 will abut against the top of the inlet pipe 7.

[0040] Embodiment 2:

[0041] See also Figure 1 , 2The utility model provides a technical solution: a continuous spray granulation equipment for industrial slurry, wherein two mounting grooves 18 are symmetrically provided on the top of the spray granulator 1, and two support bars 3 are respectively placed inside the two mounting grooves 18, and a threaded hole 19 connected to the mounting groove 18 is provided on the outer wall of the spray granulator 1; a threaded rod 20 is connected to the inner thread of the threaded hole 19; a rotating shaft 21 is fixed to one end of the threaded rod 20, and a fixing plate 22 abutting against the support bar 3 is fixed to the other end of the threaded rod 20.

Therefore, the utility model facilitates the disassembly and separation of the mixing box 4 and the spray granulator 1, thereby facilitating the cleaning and maintenance of the mixing box 4 and the spray granulator 1.

[0043] Working principle:

[0044] First, pour the liquid or semi-solid material into the mixing box 4 through the feed pipe 5, and then start the motor 9, which drives the first gear 11 to rotate through the driving rod 10, and the first gear 11 drives two sets of stirring bars 15 through two second gears 12 to stir the liquid or semi-solid material to make it fully mixed, thereby greatly improving the mixing efficiency of the liquid or semi-solid material and thus improving the granulation effect;

[0045] And because the diameter of the first gear 11 is greater than the diameter of the second gear 12, under the same output efficiency of the motor 9, the rotation speed of the second gear 12 is greater than the rotation speed of the first gear 11, thereby increasing the rotation speed of the stirring bar 15, further increasing the mixing efficiency of the liquid or semi-solid material, and thus improving the granulation effect;

[0046] And by rotating the sealing ring 17, one end of the sealing ring 17 is in contact with the top of the inlet pipe 7.

[0047] Secondly, by opening the valve body 8, the liquid or semi-solid material after stirring and mixing will enter the spray granulator 1, and the liquid or semi-solid material can be made into granular material under the action of the spray granulator 1. Then the granular material will be discharged through the discharge pipe 2, and then the granular material will be sent to the powder pressing machine to be pressed into a sheet;

[0048] Finally, by rotating the rotating shaft 21, the rotating shaft 21 drives the threaded rod 20 to move in the threaded hole 19. When the threaded rod 20 moves, it will drive the fixed plate 22 to move accordingly. After the fixed plate 22 is no longer in contact with the support bar 3, the mixing box 4 can be disassembled.
