Description

Technical Field

[0001] The utility model relates to the technical field of granulators, in particular to a dry granulator capable of preventing dust from escaping. Background Art

[0002] At present, the granulation machinery at home and abroad mainly includes dry granulation machinery, boiling spray granulation machinery and wet granulation machinery. The so-called dry granulation is to first put the powdered raw materials and auxiliary materials into the dry powder mixer to mix evenly, then transfer them to the dry granulator, press them into flakes through a group of rollers, break them into pieces through the crushing box, and then enter the granulation box for granulation, so that the flake materials become granules.

[0003] The existing public patent CN202321717606.8 is a dry granulator that prevents dust from escaping. The cooperation between the scraper and the guide block avoids the problem of dust being discharged from between the guide block and the semi-annular mesh plate, so that the dust can only pass through the semi-annular mesh plate to the bottom of the machine body, thereby enhancing the effect of collecting dust.

[0004] However, in this comparative example, if the collected powder and debris need to be reprocessed, the sealing plate at the bottom of the dust box needs to be opened, and then the powder and debris are taken out and placed using other containers and tools, and then the powder and debris can be poured back into the granulator for reprocessing. The process of taking out the powder and debris will still cause the powder and debris to float around, thereby reducing the practicality of the granulator. Utility Model Content

[0106] A sealing gasket is disposed on the outer surface of the fixing plate 25 , and a sealing member is disposed on the fixing groove 22 .

[0107] Furthermore, the first filter screen plate 10 is fixedly sleeved on the inner wall of the body 1;

[0108] Wherein, the first filter screen plate 10 is arranged at an angle;

[0109] Wherein, a plurality of dispersion columns 11 are fixedly connected to the upper surface of the first filter screen plate 10;

[0110] The upper surface of the first filter screen plate 10 and the bottom wall of the discharge frame 9 are in the same plane;

[0111] The sliding groove 17 is provided on the front surface of the body 1, and the sliding groove 17 is communicated with the interior of the body 1;

[0112] The collecting basket 16 is slidably connected to the sliding groove 17 and the body 1, and the collecting basket 16 is located at the lower side of the first filter screen plate 10;

[0113] Wherein, a sealing ring is provided between the collection basket 16 and the sliding groove 17;

[0114] The collecting basket 16 is fixed to the machine body 1 by bolts.

[0115] In this solution, the mesh size of the first filter screen plate 10 is the same as that of the second filter screen plate 15 , and the mesh size of the first filter screen plate 10 is larger than that of the third filter screen plate 20 .

[0116] In the initial state during use, the lower end of the positioning rod 26 slides into the fixing hole 24, and the rear surface of the fixing plate 25 fits with the rear inner wall of the dust box 8. At this time, the fixing plate 25 isolates the dust box 8 from the first connecting groove 6.

[0117] As mentioned above, the powdered raw materials and auxiliary materials are put into the machine body 1 through the feed hopper 7, and then the two motors 2 are started synchronously. The two motors 2 start to drive the two rotating shafts 3 to rotate in relative directions, and then synchronously drive the two pressing rollers 4 to granulate the powdered raw materials and auxiliary materials;

[0118] As mentioned above, the produced particles fall on the inclined first filter screen plate 10, and the powder and debris fall into the collection basket 16 through the first filter screen plate 10, thereby preventing the powder and debris from flying when discharging, thereby preventing the dust from escaping, optimizing the production environment, being more environmentally friendly, thereby ensuring the health of the staff, and thereby increasing the practicality of the granulator. When taking out the powder and debris, it is only necessary to disassemble the collection basket 16, which can prevent the powder and debris from escaping again.

[0119] As mentioned above, the produced particles roll down through the inclined first filter plate 10 and are then discharged from the machine body 1 through the discharge frame 9. At this time, the fan 18 is started. The start of the fan 18 generates negative pressure in the collection box 12 and the dust box 8, so that the powder and debris on the surface of the produced particles are sucked into the collection box 12 through the second filter plate 15 during the discharge process through the discharge frame 9, and then enter the dust box 8 through the first fixed pipe 13, and the powder and debris in the dust box 8 at this time are filtered through the third filter plate 20, and the filtered air is transported to the exhaust port of the fan 18 through the second fixed pipe 19 for discharge, and the powder and debris in the air will be collected in the dust box 8. When the granulation work is completed or the granulation work has been carried out for a period of time, the fan 18 is turned off, and the mounting block 27 is pulled upwards at this time. The block 27 moves upward to drive the positioning rod 26 to move up and down. In this process, the fixing spring 23 is stretched, causing the fixing spring 23 to be stretched and deformed. When the positioning rod 26 moves upward out of the fixing hole 24, the fixing plate 25 is pulled forward at this time. Under the action of gravity, the powder and debris collected in the dust box 8 will fall onto the inclined plate 5 through the first connecting groove 6, and then be used as raw materials in the granulation process. On the one hand, most of the powder and debris can be collected and reused. The powder and debris will not escape during the recycling process, thereby increasing the environmental performance of the granulator and thus improving the practicality of the granulator. On the other hand, it can avoid the escaping of powder and debris during the discharging process of the granulator to pollute the working environment, optimize the production environment, be more environmentally friendly, and thus ensure the health of the staff.

[0120] Furthermore, the dispersion column 11 can disperse the produced particles during the rolling process on the first filter screen plate 10, thereby preventing the particles from being too concentrated during discharge and from being too accumulated during discharge, which would affect the collection effect of powder and debris, thereby ensuring the effect of the granulator in preventing the powder and debris from escaping, and increasing the practicality of the granulator.

[0121] Working principle: When the device is used, the powdered raw materials and auxiliary materials are put into the machine body 1 through the feed hopper 7, and then the two motors 2 are started synchronously. The two motors 2 start to drive the two rotating shafts 3 to rotate in relative directions, and then synchronously drive the two pressing rollers 4 to granulate the powdered raw materials and auxiliary materials;

[0122] As mentioned above, the produced particles fall on the inclined first filter screen plate 10, and the powder and debris fall into the collection basket 16 through the first filter screen plate 10, thereby preventing the powder and debris from flying when discharging, thereby preventing the dust from escaping, optimizing the production environment, being more environmentally friendly, thereby ensuring the health of the staff, and thereby increasing the practicality of the granulator. When taking out the powder and debris, it is only necessary to disassemble the collection basket 16, which can prevent the powder and debris from escaping again.

[0123] As mentioned above, the produced particles roll down through the inclined first filter plate 10 and are then discharged from the machine body 1 through the discharge frame 9. At this time, the fan 18 is started. The start of the fan 18 generates negative pressure in the collection box 12 and the dust box 8, so that the powder and debris on the surface of the produced particles are sucked into the collection box 12 through the second filter plate 15 during the discharge process through the discharge frame 9, and then enter the dust box 8 through the first fixed pipe 13, and the powder and debris in the dust box 8 at this time are filtered through the third filter plate 20, and the filtered air is transported to the exhaust port of the fan 18 through the second fixed pipe 19 for discharge, and the powder and debris in the air will be collected in the dust box 8. When the granulation work is completed or the granulation work has been carried out for a period of time, the fan 18 is turned off, and the mounting block 27 is pulled upwards at this time. The block 27 moves upward to drive the positioning rod 26 to move up and down. In this process, the fixing spring 23 is stretched, causing the fixing spring 23 to be stretched and deformed. When the positioning rod 26 moves upward out of the fixing hole 24, the fixing plate 25 is pulled forward at this time. Under the action of gravity, the powder and debris collected in the dust box 8 will fall onto the inclined plate 5 through the first connecting groove 6, and then be used as raw materials in the granulation process. On the one hand, most of the powder and debris can be collected and reused. The powder and debris will not escape during the recycling process, thereby increasing the environmental performance of the granulator and thus improving the practicality of the granulator. On the other hand, it can avoid the escaping of powder and debris during the discharging process of the granulator to pollute the working environment, optimize the production environment, be more environmentally friendly, and thus ensure the health of the staff.
