Description

Technical Field

[0001] The invention relates to the technical field of solid waste treatment, in particular to a forming and granulating device for preparing fuel particles by utilizing solid waste. Background Art

[0002] Fly ash generated by sludge incineration, semi-dry flue gas purification and garbage incineration contains a large amount of harmful substances and can easily pollute groundwater, soil and air. After being collected and processed, these fly ashes can be used in various fields. For example, calcium in fly ash can be converted into cement clinker, and dioxins can be decomposed at high temperatures to solidify heavy metals. Therefore, equipment for recycling fly ash is used in various fields.

[0003] For example, the invention of patent application number 202010530638.1 discloses a fly ash stabilization granulation system and working method, including: a feeding device, a granulation device and a screening device; the feeding device is suitable for collecting the chelated fly ash and evenly transporting it to the granulation device for primary granulation; the granulation device is suitable for roller granulating the chelated fly ash.

[0004] Taking the above-mentioned fly ash granulation system as an example, the collection, mixing, feeding and granulation of fly ash are distributed in a system with a long processing cycle. After the fly ash is collected, it needs to be transported over long distances using pipelines. However, high-temperature flue gas can easily cause water droplets to condense on the inner wall of the transportation pipeline. When the fly ash is damp, it is easy for it to stick to the inner wall of the transportation pipeline and become blocked. It is necessary to check a longer transportation pipeline before it can be unblocked, which affects the fly ash granulation speed. Summary of the Invention

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. When the present application is used, the high-temperature flue gas collides with the low-temperature airflow, which carries a small amount of low-temperature liquid. The high-temperature flue gas condenses, and the dust in the high-temperature flue gas condenses into large particles. The high temperature of the high-temperature flue gas itself condenses the dust into large particles. The flue gas needs to pass through the second filter element and then enter the ash inlet trough into the interior of the equipment housing. The flue gas passes through the small holes and the first filter element and then enters the conveying pipe. The second filter element intercepts the large particles in the flue gas while the temperature of the flue gas discharged into the conveying pipe is cooled once. In the process of intercepting and collecting dust in the flue gas, the molding and granulation equipment of the present application cools the high-temperature flue gas to reduce dust pollution and heat pollution. The low-temperature airflow carries a small amount of low-temperature liquid. In the process of high-temperature flue gas and low-temperature airflow colliding to gather large particles, the pre-prepared liquid that plays a bonding role combines with the dust to complete the work of adding adhesive to the dust. The dust in the flue gas is collected and the granulation pretreatment work is completed at the same time. There is no need to transport the dust after collection, thereby ensuring the quality of dust collection and granulation.

[0018] 2. When the present application is used, the vacuum pump extracts air from the inside of the delivery pipe through the air guide pipe three and the solenoid valve one, and then delivers the gas to the inside of the diverter box two at the bottom of the inner cavity of the cooling box one through the air guide pipe two, so as to perform secondary cooling of the flue gas. The low-temperature liquid in the cooling box two enters the inside of the diverter box three through the solenoid valve four and the guide pipe one, and the diverter box three with multiple circular holes three sprinkles the liquid to multiple positions inside the cooling box one, ensuring that a certain level of low-temperature liquid is maintained inside the cooling box one, thereby ensuring the cooling effect of the airflow and flue gas, and fully and evenly mixing a certain amount of liquid with adhesive effect into the dust particles, thereby ensuring the success rate of dust granulation.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Example: Figures 1-13 As shown, the present invention provides a technical solution for a forming and granulating device for preparing fuel particles using solid waste, including an equipment installation box 1, a material receiving and granulating structure is arranged inside the equipment installation box 1, the material receiving and granulating structure includes an equipment housing 2 rotatably arranged inside the equipment installation box 1, a reciprocating screw 6 rotatably inserted on the equipment housing 2, and a granulating drive assembly installed outside the reciprocating screw 6, a dust processing structure is connected to the top of the equipment housing 2, the dust processing structure includes a dust recovery frame 23 connected to the equipment housing 2, a material blocking assembly rotatably arranged inside the dust recovery frame 23, a cooling box 37 connected to one side of the dust recovery frame 23, and a circulating air supply assembly installed outside the cooling box 37.

[0035] Specifically, such as Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 and Figure 7 As shown, an electromagnet member 4 and a plurality of mounting frames 3 are rotatably mounted on the outside of the device housing 2, and the electromagnet member 4 and the plurality of mounting frames 3 are fixedly mounted inside the device installation box 1. The device housing 2 can rotate inside the device installation box 1, and the end of the device housing 2 away from the granulation drive assembly is rotatably connected to the installation box 16. The installation box 16 is fixedly mounted on one end of the device installation box 1 and cannot move. A filter mesh member 18 is rotatably mounted inside the installation box 16, and the filter mesh member 18 can rotate inside the installation box 16. The filter mesh member 18 can rotate synchronously with the device housing 2, and a plurality of small holes 21 are provided on one side of the filter mesh member 18 and one side of the installation box 16.

[0036] A plurality of card slots 17 are provided inside the installation box 16, and a card plate 19 provided inside the card slot 17 is fixedly connected to a filter mesh part 18. One end of the reciprocating screw rod 6 extends to the outside of the equipment installation box 1 after passing through the installation box 16. A plurality of blades 15 fixedly installed on the outside of one end of the reciprocating screw rod 6 are all provided on the outside of the equipment installation box 1. The blades 15 rotate synchronously with the reciprocating screw rod 6, and the reciprocating screw rod 6 is rotationally connected to the installation box 16. The rotation of the reciprocating screw rod 6 will not be affected by the installation box 16. A magnet part 20 is fixedly installed inside the filter mesh part 18. The magnet part 20 is rotatably sleeved on the outside of the reciprocating screw rod 6, and the magnet part 20 is adsorbed and fixed to the reciprocating screw rod 6 by magnetic force.

[0037] The output end of the forward and reverse motor 5 is fixedly connected to the reciprocating screw 6. When the forward and reverse motor 5 rotates forward and drives the reciprocating screw 6 to rotate clockwise, the reciprocating screw 6 drives the filter mesh part 18 to rotate clockwise through the magnet part 20. The filter mesh part 18 drives the card plate 19 to rotate clockwise inside the card slot 17. The shape of the card slot 17 is pre-calculated and designed. When the card plate 19 rotates and presses against the installation box 16, the rotation of the filter mesh part 18 is restricted, the magnet part 20 is restricted, the reciprocating screw 6 continues to rotate while the filter mesh part 18 cannot rotate. At this time, the small hole 21 opened in the filter mesh part 18 is aligned with the multiple small holes 21 opened in the installation box 16, and the equipment housing 2 enters the granulation state.

[0038] When the forward and reverse motor 5 works in reverse to drive the reciprocating screw 6 to rotate counterclockwise, the reciprocating screw 6 drives the filter mesh 18 to rotate counterclockwise through the magnet 20. When the clamping plate 19 abuts against the installation box 16, the filter mesh 18 stops rotating, and the small holes 21 opened in the filter mesh 18 are staggered with the multiple small holes 21 opened in the installation box 16, and the equipment housing 2 enters the material storage state.

[0039] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, a blower 45 is provided on the outside of the equipment installation box 1, and a conveying pipe 44 is fixedly installed on the air outlet end of the blower 45. The conveying pipe 44 is provided on one side of the installation box 16, and multiple blades 15 are provided inside the conveying pipe 44. The particles cut by the rotating blades 15 fall into the conveying pipe 44. The working blower 45 conveys airflow to the inside of the conveying pipe 44. The airflow conveys and dries the particles, thereby completing the particle cleaning work.

[0040] A filter mesh component 3 46 is fixedly installed on the top of the delivery pipe 44. The setting of the filter mesh component 3 46 allows the inside of the delivery pipe 44 to communicate with the outside world. A solenoid valve 2 47 is set on the top of the filter mesh component 3 46. By controlling the operation of the solenoid valve 2 47 fixedly installed on the top of the delivery pipe 44, the delivery pipe 44 can be connected to the outside world.

[0041] Specifically, such as Figure 1 、 Figure 5 and Figure 6 As shown, the forward and reverse motor 5 in the granulation drive assembly is fixedly installed on the end of the equipment installation box 1 away from the installation box 16, the output end of the forward and reverse motor 5 is fixedly connected to the reciprocating screw 6, the inner ring of the one-way bearing 9 is fixedly installed on the outside of the reciprocating screw 6, the gear 1 7 is fixedly installed on the outside of the outer ring of the one-way bearing 9, and the mounting shaft 10 is fixedly installed inside the gear 2 8 engaged with the gear 1 7. The mounting shaft 10 is fixedly connected to the equipment installation box 1, and the mounting shaft 10 supports the gear 2 8 so that the gear 2 8 can only rotate on its own. The inner gear ring 11 engaged on the outside of the gear 2 8 is fixedly connected to the equipment housing 2.

[0042] When the forward and reverse motors 5 work in reverse, the equipment housing 2 is in a material storage state. At this time, the reciprocating screw 6 rotates in the self-locking direction between the inner and outer rings of the one-way bearing 9. At this time, the reciprocating screw 6 rotates through the one-way bearing 9, gear 1 7, gear 2 8, inner gear ring 11 and other structures to drive the equipment housing 2 to rotate. The rotating equipment housing 2 plays a role in mixing the internally stored materials, thereby preventing the materials inside the equipment housing 2 from agglomerating and affecting the granulation quality.

[0043] A one-way bearing 12 is installed on the outside of the reciprocating screw 6 through a nut pair. The outer ring of the one-way bearing 12 is fixedly connected to the ring 13. The one-way bearing 12 and the ring 13 are both arranged on one side of the inside of the equipment housing 2. One end of the two support shafts 14 passed through the ring 13 is fixedly connected to the inner wall of the equipment housing 2. Under the action of the support shafts 14, the rotation of the reciprocating screw 6 cannot directly drive the ring 13 to rotate. When the forward and reverse motor 5 reverses and the equipment housing 2 is in the material storage state, the rotation direction of the reciprocating screw 6 is the rotation direction between the inner and outer rings of the one-way bearing 12, and the ring 13 remains stationary.

[0044] When the forward and reverse motors 5 are working in forward rotation, the device housing 2 is in a granulating state. At this time, the rotation direction of the reciprocating screw 6 is the rotation direction between the inner and outer rings of the one-way bearing 1 9. The rotation of the reciprocating screw 6 will not apply force to the device housing 2. At this time, the electromagnet 4 works to adsorb and fix the device housing 2 through magnetic force, and the position of the device housing 2 is restricted. At this time, the rotation direction of the reciprocating screw 6 is the self-locking direction between the inner and outer rings of the one-way bearing 2 12. The reciprocating screw 6 drives the one-way bearing 2 12 and the ring 13 to reciprocate inside the device housing 2, applying thrust to the dust inside the device housing 2.

[0045] Specifically, such as Figure 2 、 Figure 8 、 Figure 10 、 Figure 12 and Figure 13 As shown, the solenoid valve 43 in the circulating air supply component is fixedly installed on one side of the delivery pipe 44, and one end of the air guide pipe 3 42 fixedly installed on one side of the solenoid valve 43 is fixedly connected to the impeller box 41, and the air guide pipe 2 40 is fixedly connected between the impeller box 41 and the bottom of the cooling box 37. The top of the diverter box 2 38 arranged on the top of the air guide pipe 2 40 is provided with multiple circular holes 2 39, and the diverter box 2 38 is fixedly installed at the bottom of the inner cavity of the cooling box 37. The diverter box 2 38 with multiple circular holes 2 39 has the effect of evenly distributing the airflow delivered by the air guide pipe 2 40 to various positions at the bottom of the inner cavity of the cooling box 37.

[0046] A driving motor 48 is fixedly installed on one side of the cooling box 37, and an impeller box 2 51 is provided on one side of the impeller box 41. Impeller 1 50 is rotatably installed inside the impeller box 41, and impeller 2 52 is rotatably installed inside the impeller box 2 51. A long shaft 49 is fixedly installed on the output end of the driving motor 48. The long shaft 49 passes through impeller 1 50 and impeller 2 52 and is fixedly connected to impeller 1 50 and impeller 2 52. When the driving motor 48 drives the long shaft 49 to rotate, the long shaft 49 drives impeller 1 50 and impeller 2 52 to rotate.

[0047] The rotating impeller 50 and the impeller box 41 form an air pump, the air guide pipe 3 42 is connected to the air inlet end of the air pump, and the air guide pipe 2 40 is connected to the air outlet end of the air pump. When the driving motor 48 is working, the air pump draws air from the inside of the delivery pipe 44 through the air guide pipe 3 42 and the solenoid valve 1 43, and then delivers the air flow to the inside of the diversion box 2 38 at the bottom of the inner cavity of the cooling box 1 37 through the air guide pipe 2 40.

[0048] In addition, because the top of both sides of the dust recovery rack 23 is fixedly installed with a diversion box 32, the diversion box 32 is provided with multiple circular holes 33 on the side facing the dust recovery rack 23, and the multiple circular holes 33 have a diversion effect. One side of one of the diversion boxes 32 is fixedly connected to an exhaust pipe 34, and the exhaust pipe 34 injects flue gas into the dust recovery rack 23. A one-way valve 35 is fixedly installed on one side of the other diversion box 32, and an air guide pipe 36 is fixedly connected between the one-way valve 35 and the top of the cooling box 37; therefore, the airflow delivered to the cooling box 37 through the air guide pipe 40 enters the dust recovery rack 23 through the air guide pipe 36, the one-way valve 35 and the diversion box 32; the solenoid valve 47 is in a normally open state, meeting the need to extract air and relieve pressure from the inside of the delivery pipe 44.

[0049] And when the driving motor 48 is working, the rotating impeller 2 52 and the impeller box 1 41 form a water pump, and a one-way valve 2 53 is fixedly installed between the water outlet of the water pump and the bottom of the cooling box 2 54. The one-way valve 2 53 prevents the liquid inside the cooling box 2 54 from flowing back into the impeller box 2 51. The water inlet end of the water pump is fixedly installed with a guide pipe 2 61, one end of the guide pipe 2 61 extends to the inside of the cooling box 1 37, and the bottom of the guide pipe 2 61 is at a certain distance from the bottom of the inner cavity of the cooling box 1 37. The water pump extracts liquid from the inside of the cooling box 1 37 through the guide pipe 2 61 and then transports it to the inside of the cooling box 2 54 through the one-way valve 2 53. The high-speed flowing liquid stirs the liquid inside the cooling box 2 54, so that the liquid inside the cooling box 2 54 is evenly cooled.

[0050] A solenoid valve four 57 is fixedly installed inside the cooling box two 54, and a diversion pipe one 58 is fixedly installed between the solenoid valve four 57 and the diversion box three 59. A plurality of circular holes three 60 are opened on one side of the diversion box three 59. The plurality of circular holes three 60 divert the liquid entering the diversion box three 59, so that the liquid entering is splashed to multiple positions inside the cooling box one 37; a plurality of cooling fins 56 are fixedly penetrated on both sides of the cooling box two 54, and the cooling end of the cooling fin 56 is arranged inside the cooling box two 54 to cool the liquid inside the cooling box two 54. A solenoid valve three 55 is fixedly installed on the top of the cooling box two 54. After the solenoid valve three 55 is opened, the liquid can be added to the cooling box two 54.

[0051] Specifically, such as Figure 8 、 Figure 9 and Figure 11 As shown, the second mounting frame 22 in the material blocking assembly is fixedly installed at the bottom of the dust recovery frame 23, and the second mounting frame 22 is rotatably installed on the outside of the equipment housing 2, and the outside of the second mounting frame 22 and the outside of the equipment housing 2 are both provided with dust inlet grooves 24. When the ash inlet groove 24 opened on the second mounting frame 22 is aligned with the ash inlet groove 24 opened on the equipment housing 2, the interior of the equipment housing 2 is connected with the interior of the dust recovery frame 23.

[0052] A mounting frame 3 25 is rotatably provided inside the dust recovery frame 23, and a plurality of filter mesh members 2 26 are fixedly installed on the outside of the mounting frame 3 25. A brake 28 is sleeved on the outside of one end of the mounting frame 3 25 located outside the dust recovery frame 23. The outer shell of the brake 28 is fixedly connected to the dust recovery frame 23. When the brake 28 is controlled to work, the brake 28 brakes and limits the mounting frame 3 25, and the mounting frame 3 25 cannot rotate.

[0053] The molding and granulating equipment is composed of an equipment installation box 1, a material receiving and granulating structure, a dust processing structure, a blower 45, a conveying pipe 44 and other structures. It is an existing technology to connect the molding and granulating equipment to a human-computer interaction device to control its operation, which will not be described in detail here.

[0054] The working principle of the molding granulation equipment is as follows:

[0055] The molding and granulating equipment is controlled to enter the initial state. The initial state is that after the equipment housing 2 enters the material storage state, the ash inlet trough 24 opened in the equipment housing 2 is aligned with the ash inlet trough 24 opened in the mounting frame 22, the forward and reverse motors 5 stop working, and the electromagnet part 4 works to limit the position of the equipment housing 2.

[0056] Then, the flue gas is discharged to the inside of the dust recovery rack 23 through the exhaust pipe 34 and the diverter box 32 fixedly installed on the exhaust pipe 34. At the same time, the driving motor 48 is controlled to work, and the vacuum pump conveys airflow to the inside of the dust recovery rack 23 through the cooling box 37, the air guide pipe 36, the one-way valve 35, and the diverter box 32 fixed with the one-way valve 35. The diverter box 32 with multiple circular holes 33 plays a role in dispersing and guiding the gas, so the airflow and the flue gas collide after being spread out; and the airflow passing through the inside of the cooling box 37 is dispersed by the diverter box 38 with multiple circular holes 39 and moves upward. During the upward movement of the airflow, it passes through the low-temperature liquid stored in the cooling box 37; therefore, the low-temperature airflow collides with the high-temperature flue gas, and the low-temperature airflow carries a small amount of low-temperature liquid. The high-temperature flue gas condenses, and the dust in the high-temperature flue gas condenses into large particles. The high temperature of the flue gas itself condenses the dust into large particles of dust. The flue gas needs to pass through the filter mesh 26 and then enter the ash inlet 24 into the equipment housing 2. The flue gas passes through the small hole 21 and the filter mesh 18 and then enters the conveying pipe 44. The filter mesh 26 intercepts the large particles in the flue gas, and the temperature of the flue gas discharged into the conveying pipe 44 is cooled once. In the process of intercepting and collecting dust in the flue gas, the molding granulation equipment in this application cools the high temperature flue gas to reduce dust pollution and heat pollution, and the low temperature air flow carries a small amount of low temperature liquid. In the process of high temperature flue gas and low temperature air flow colliding to gather large particles, the pre-modulated liquid that plays a bonding role combines with the dust to complete the work of adding adhesive to the dust. The dust in the flue gas is collected and the granulation pretreatment work is completed at the same time. There is no need to transport the dust after collection, thereby ensuring the quality of dust collection and granulation.

[0057] After the vacuum pump extracts air from the inside of the delivery pipe 44 through the air guide pipe 3 42 and the electromagnetic valve 1 43, the gas is transported to the inside of the diversion box 2 38 at the bottom of the inner cavity of the cooling box 1 37 through the air guide pipe 2 40 to perform secondary cooling on the flue gas. After the molding and granulation equipment has been working for a period of time, the vacuum pump extracts the flue gas after the initial cooling and transports it to the inside of the cooling box 1 37. The water pump extracts liquid from the inside of the cooling box 1 37 through the guide pipe 2 61 and transports it to the inside of the cooling box 2 54 through the impeller 2 52. The high-speed flowing liquid stirs the liquid inside the cooling box 2 54, so that the cooling box 2 54 The internal liquid is cooled at a high speed. A guide pipe 1 58 is fixedly installed between the electromagnetic valve 4 57 and the diverter box 3 59. Therefore, the low-temperature liquid in the cooling box 2 54 enters the diverter box 3 59 through the electromagnetic valve 4 57 and the guide pipe 1 58. The diverter box 3 59 with multiple circular holes 3 60 sprinkles the liquid to multiple positions inside the cooling box 1 37 to ensure that a certain level of low-temperature liquid is maintained inside the cooling box 1 37, which can ensure the cooling effect of the airflow and flue gas, and fully and evenly mix a certain amount of liquid with adhesive effect into the dust particles to ensure the success rate of dust granulation.

[0058] After the flue gas is supplied for a period of time, the control brake 28 stops working for a period of time and then works again, causing the mounting frame 3 25 to lose its limit for a period of time. At this time, the several filter elements 26 on the top have trapped a large amount of dust particles. The weight of the top and bottom of the outer side of the mounting frame 3 25 is unbalanced. In addition, the airflow moving into the equipment housing 2 applies a thrust to the filter element 26, causing the filter element 2 26 that has trapped a large amount of dust to drive the mounting frame 3 25 to rotate. The filter element 2 26 that has trapped dust rotates to the bottom, and the trapped dust enters the equipment housing 2 through the ash inlet chute 24 for storage. After colliding with the low-temperature gas, the flue gas passes through multiple filter elements 2 26. The flue gas speed is not enough to push the dust inside the equipment housing 2 toward the mounting box 16. After the rotation and repositioning, the dust-trapping side of the filter element 2 26 is in front of the direction of the flue gas, and the filter element 2 26 is cleared by the backflow of the flue gas. The multiple filter elements 2 26 can work alternately to reduce the possibility of filter element 2 26 being blocked, ensuring the dust trapping effect while ensuring smooth flue gas flow.

[0059] The electromagnet part 4 is also controlled to work again after pausing for a period of time. During this process, the forward and reverse motor 5 reverses and drives the device housing 2 to rotate for multiple cycles. After the forward and reverse motor 5 stops working, the device housing 2 resumes communication with the inside of the dust recovery rack 23. During the rotation of the device housing 2, the dust stored inside the device housing 2 is thrown up and then falls down, which has a uniform material effect, so that the amount of dust at each position inside the device housing 2 is roughly the same, providing space for the dust trapped inside the dust recovery rack 23 to enter the interior of the device housing 2.

[0060] At the end of a flue gas supply, the solenoid valve four 57 is controlled to close, and the liquid inside the cooling box two 54 no longer moves into the cooling box one 37. The working water pump transports most of the liquid inside the cooling box one 37 to the cooling box two 54. Multiple filter mesh parts two 26 and filter mesh parts one 18 filter and intercept dust in the flue gas until the liquid inside the cooling box one 37 is used up, and the flue gas supply is stopped. Then, the electromagnet part 4 is controlled to stop working, and the forward and reverse motors 5 are controlled to reverse and drive the equipment housing 2 to rotate for multiple cycles to mix the dust inside the equipment housing 2. After the forward and reverse motors 5 have finished working, the electromagnet part 4 is controlled to limit the equipment housing 2.

[0061] Finally, the forward and reverse motor 5 is controlled to rotate forward, and the equipment housing 2 enters the granulation state. The small hole 21 opened in the filter mesh 18 is aligned with the multiple small holes 21 opened in the installation box 16. As the working time of the forward and reverse motor 5 increases, the one-way bearing 2 12 and the ring 13 move toward the installation box 16. The dust is subjected to a certain pressure and is shaped through the small hole 21 and enters the inside of the conveying pipe 44. The rotating reciprocating screw 6 drives the rotating multiple blades 15 to cut the dust, so that the dust falls into the inside of the conveying pipe 44 in the form of particles. At the same time, the solenoid valve 2 47 is controlled to work closed, and the blower 45 conveys airflow to the inside of the conveying pipe 44 to convey the dust particles to a preset position for collection, thereby completing the granulation work.

[0062] In addition, such as Figure 7 As shown, a humidity sensor is fixedly installed on the bottom of one side of the installation box 16 provided inside the equipment casing 2 to detect the humidity of the dust inside the equipment casing 2. Before the granulation work is carried out, when the dust humidity is too high, the forward and reverse motors 5 are controlled to reverse and drive the equipment casing 2 to rotate, so that the dust inside the equipment casing 2 moves, and at the same time, flue gas is infused into the dust recovery rack 23. The high-temperature flue gas dries the dust during the flow inside the equipment casing 2. The forward and reverse motors 5 are suspended once at regular intervals, and whether the forward and reverse motors 5 continue to work is determined based on the dust humidity inside the equipment casing 2.

[0063] When the dust humidity inside the device housing 2 is too low, the solenoid valve 4 57 is controlled to open, liquid is added to the cooling box 1 37, and the drive motor 48 is controlled to work, and moist air flow is added to the inside of the device housing 2 to humidify the dust. The forward and reverse motors 5 reverse to drive the device housing 2 to rotate, and the dust inside the device housing 2 moves. The forward and reverse motors 5 pause once at regular intervals, and whether the forward and reverse motors 5 continue to work is determined based on the dust humidity inside the device housing 2.

[0064] When the dust humidity inside the device housing 2 is within a preset range, granulation is performed.

[0065] In addition, such as Figure 11As shown, a groove 1 27 is provided between two adjacent filter mesh members 2 26, and the groove 1 27 is provided on the outside of the mounting frame 3 25. A sampling rod 30 is inserted into the mounting frame 3 25. The mounting frame 3 25 and the sampling rod 30 are in an interference fit state. A groove 2 31 is provided on the outside of the sampling rod 30, and the groove 2 31 is aligned with one groove 1 27. After the control brake 28 stops working, the mounting frame 3 25 is manually operated to rotate, and the mounting frame 3 25 and the sampling rod 30 rotate to throw out the dust inside the groove 2 31. After a period of time, the mounting frame 3 25 is operated. Rotate to align the pointing plate 29 fixed on the outside of the sampling rod 30 with the preset mark on the brake 28, and then control the brake 28 to work. At this time, the groove 1 27 is facing the top of the inner cavity of the dust recovery frame 23, and some large particles formed by the condensation of dust in the high-temperature flue gas fall into the inside of the groove 2 31; after a period of time, after restricting the mounting frame 3 25, the brake 28 is controlled to stop working, and most of the sampling rod 30 is pulled to the outside of the mounting frame 3 25. The number of large particles in the groove 2 31 is observed, and data can be collected to determine whether the molding and granulation equipment is working normally.
