DETAILED DESCRIPTION

[0022] 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.

[0023] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings.

A cooling component 4 for cooling is arranged inside the box body 1, and a cleaning component 5 for cleaning the gas generated by granulation is arranged between the box body 1 and the granulator body 3.

[0025] The utility model is further described below in conjunction with embodiments.

[0026] Embodiment 1:

[0027] See also Figure 1-Figure 6 The cleaning assembly 5 includes an annular baffle 51 threadedly connected to one side of the support column 2, and an activated carbon filter 52, a high-efficiency filter 53 and a primary filter 54 are arranged on one side of the annular baffle 51 in sequence. An annular air duct 55 is arranged on the upper surface of the box body 1, and an air outlet 56 is opened on the outer surface of the annular air duct 55. A connecting pipe A57 is arranged on the outer surface of the annular air duct 55, and one end of the connecting pipe A57 passes through the annular baffle 51 and is connected to a fan 58. An air outlet 59 is opened on the upper surface of the annular baffle 51. The gas after the particulate matter contacts the cooling water first passes through the preliminary filter 59. The net 53 removes large particles of impurities, and then passes through the high-efficiency filter net 52, which is a HEPA filter, to further filter fine particles and harmful substances. Finally, the activated carbon filter net 52 adsorbs odors and organic pollutants in the gas, and the cleaned gas is discharged through the air outlet 59. Because the upper surface of the box body 1 is provided with an annular air duct 55 and an air outlet 56, the annular air duct 55 is connected to the fan, so the gas flow can be increased, thereby increasing the cleaning effect. In addition, since the annular baffle 51 and the support column 2 are connected by bolt threads, it is convenient for subsequent disassembly and cleaning.

[0028] A feed hopper 31 is disposed on the upper surface of the granulator body 3 , and a discharge hopper 32 is disposed at the bottom of the granulator body 3 . Raw materials are added from the feed hopper 31 , and granules after granulation are discharged from the discharge hopper 32 .

[0029] The cooling assembly 4 includes a water tank 41 and a water pump 42 arranged on one side of the box body 1, and a connecting pipe B43 arranged at one end of the water pump 42. The water tank 41 is connected to the water pump 42. An annular water pipe 44 is arranged at one end of the connecting pipe B43. A nozzle 45 is arranged on the outer surface of the annular water pipe 44. A mounting block 46 is arranged on the outer surface of the annular water pipe 44. The upper surface of the mounting block 46 is connected to the bottom of the discharge hopper 32. The cooling water in the water tank 41 is pumped into the annular water pipe 44 through the water pump 42 and sprayed out through the nozzle 45. Because the annular water pipe 44 is located at the discharge hopper 43, it can not only make the water flow more uniform and gentle in contact with the particles, but also avoid excessive heat transfer and rapid generation of a large amount of water vapor.

[0030] A support platform 6 is arranged inside the box body 1, and two groups of support platforms 6 are arranged. Moving grooves 61 are opened on the upper surfaces of the two groups of support platforms 6. A motor 62 is arranged inside one group of moving grooves 61, and a screw rod 63 is arranged at the output end of the motor 62. The outer surface of the screw rod 63 is threadedly connected with a connecting block 64. A guide rod 65 is arranged inside the other group of moving grooves 61, and a guide block 66 is sleeved on the outer surface of the guide rod 65. A grid plate 67 is arranged between the connecting block 64 and the guide block 66. The grid plate 67 can catch the particles discharged from the discharge hopper, and then through the movement of the moving grooves 61, the particles can be more evenly contacted with the cooling water in the box body 1, so as to be fully cooled.

[0031] An electric push rod 7 is provided inside the connecting block 64 and the guide block 66. The telescopic end of the electric push rod 7 is connected to the bottom of the mesh plate 67.

The grid plate 67 is located inside the water reservoir 8 to facilitate cleaning of the water reservoir 8. The drain pipe 81 facilitates the discharge of cooling water.

[0033] Specifically, raw materials are added from the feed hopper 31, and the granulated particles are discharged from the discharge hopper 32. At the same time, the cooling water in the water tank 41 is pumped into the annular water pipe 44 through the water pump 42 and sprayed out through the nozzle 45. Because the annular water pipe 44 is located at the discharge hopper 43, it can not only make the water flow more uniform and gentle in contact with the particles, but also avoid excessive heat transfer and the generation of a large amount of water vapor. The grid plate 67 can catch the particles discharged from the discharge hopper, and then through the movement of the moving groove 61, the particles can be more evenly contacted with the cooling water in the water tank 8 in the box body 1, so as to be fully cooled. The grid plate 67 can also be extended by the electric push rod 7 to drive the particles to leave the box body 1, so that the particles can be The surface of the particles is drained, and the drain pipe 81 facilitates the discharge of cooling water. In the above process, the gas after the particles contact the cooling water first passes through the preliminary filter 53 to remove large particle impurities, and then passes through the high-efficiency filter 52, which is a HEPA filter, to further filter fine particles and harmful substances. Finally, the activated carbon filter 52 adsorbs odors and organic pollutants in the gas, and the cleaned gas is discharged through the air outlet 59. Because the upper surface of the box body 1 is provided with an annular air duct 55 and an air outlet 56, the annular air duct 55 is connected to the fan, so that the gas flow can be increased, thereby increasing the cleaning effect, and because the annular baffle 51 and the support column 2 are connected by bolt threads, it is convenient for subsequent disassembly and cleaning.
