After the collection is completed, the push rod 65 is pushed, and the push rod 65 drives the fixed rod 64 to move upward. The movement of the fixed rod 64 drives the fixed slider 66 to move and compress the fixed spring 67, so that the fixed rod 64 is disengaged from the fixed hole. Then the positioning block 62 and the positioning seat 61 can be separated, so that the collecting trolley 63 can be pushed away, so that when the device is in use, it is convenient to collect and transfer the granulated combustion-supporting agent, thereby improving the practicality of use.

After the collection is completed, the push rod 65 is pushed, and the push rod 65 drives the fixed rod 64 to move upward. The movement of the fixed rod 64 drives the fixed slider 66 to move and compress the fixed spring 67, so that the fixed rod 64 is disengaged from the fixed hole. Then the positioning block 62 and the positioning seat 61 can be separated, so that the collecting trolley 63 can be pushed away, so that when the device is in use, it is convenient to collect and transfer the granulated combustion-supporting agent, thereby improving the practicality of use.

[0037] The structure and use principle of the granulator body 1, the dust collection component 4 and the discharge component 5 in the utility model have been disclosed in a granulator for flame retardant production disclosed in Chinese patent application No. 202120924903.4. Its working principle is that the flame retardant enters the inside of the main body through the feed hopper 2, and the granulation roller drives the granulation knife to rotate to cut and granulate the flame retardant, and the granulation effect is good; the cold air enters the air distribution chamber through the input pipe and then disperses into the air distribution pipe. The cold air flows in the air distribution pipe to take away the heat of the granulation roller and the granulation knife, reducing the damage to the crushing roller and the crushing knife caused by the high temperature, effectively protecting the crushing roller and the crushing knife, extending the service life of the granulation device, and reducing the production cost; because the air distribution pipe corresponds to the crushing knife one by one and is located at the crushing knife Nearby, the crushing knife is evenly cooled, so that the crushing knife is evenly and fully cooled, and it is avoided that some crushing knives are unevenly cooled and cause low cooling effect and poor cooling effect; the exhaust component absorbs the powder to prevent the powder from diffusing into the external environment, ensuring the cleanliness of the working environment and the health of the staff; the two exhaust units located on the right side of the granulating roller and above the right side of the guide plate perform double suction of powder inside the main body, which is beneficial to enhance the efficiency of powder removal; the flame retardant particles granulated by the granulating roller are sucked away by the exhaust unit, and the flame retardant particles fall on the guide plate and slide down along its inclined surface. In the process of the flame retardant particles sliding down, the powder is sucked away by the exhaust unit above the guide plate, ensuring that the powder is cleanly sucked away, and finally the flame retardant particles slide to the discharge port and are finally discharged through the discharge port.

[0038] Working principle and use process of the utility model: In the utility model, the flame retardant enters the interior of the main body through the feed hopper 2, and is granulated through the granulator body 1. During granulation, the generated dust is collected and processed by the dust suction component 4, and the chopped combustion-supporting agent is screened through the screening component 3, and then discharged through the discharging component 5. After discharge, it is collected and transferred through the collecting component 6. When the screening component 3 is in use, the screening motor 39 is started, and the screening motor 39 drives the rotating rod 38 to rotate, and the rotation of the rotating rod 38 drives the top rod 37 to rotate, thereby cooperating with the elastic seat 35 and the reset spring 36 to drive the screen 34 to move upward to screen the combustion-supporting agent. When the screened combustion-supporting agent needs to be taken out, the clamping rod 332 is pulled, and the clamping rod 332 drives the clamping slider 333 to move the pressure The clamping spring 334 is compressed to make the clamping rod 332 disengage from the clamping hole, and then the screening seat 32 can be pulled out to take out the screened combustion aid, so that the device can be used to screen the flame retardant after granulation, thereby improving the practicality of use. When the collecting component 6 is in use, the discharged combustion aid enters the collecting trolley 63 for collection. After the collection is completed, the push rod 65 is pushed, and the push rod 65 drives the fixed rod 64 to move upward. The movement of the fixed rod 64 drives the fixed slider 66 to move and compress the fixed spring 67, so that the fixed rod 64 disengages from the fixed hole, and then the positioning block 62 and the positioning seat 61 can be separated, so that the collecting trolley 63 can be pushed away, so that the device can be used to collect and transfer the combustion aid after granulation, thereby improving the practicality of use.
