Description

Technical Field

[0001] The present invention relates to the technical field of solid waste treatment, and specifically to a forming and granulating device for preparing fuel pellets from solid waste. Background Art

[0002] Fly ash generated after sludge incineration, semi-dry flue gas purification, and garbage incineration contains a large amount of harmful substances and is likely to pollute groundwater, soil, and air. After collection and processing of this fly ash, it can be applied in various fields. For example, calcium in the fly ash can be converted into cement clinker, while dioxins are decomposed at high temperature and heavy metals are solidified. Therefore, equipment for recycling fly ash is applied in various fields.

[0003] For example, a fly ash stabilization granulation system and working method disclosed in the invention with patent application number 202010530638.1 includes: a feeding device, a granulating device, and a screening device; the feeding device is adapted to collect the chelated fly ash transported and uniformly transport it into the granulating device for primary granulation; the granulating device is adapted to roll and granulate the chelated fly ash.

[0004] Taking the above fly ash granulation system as an example, the collection, mixing, feeding, and granulation of fly ash are distributed on a system with a relatively long processing cycle. After the fly ash is collected, it needs to be transported over a long distance using pipelines. However, high-temperature flue gas easily causes water droplets to condense on the inner wall of the transport pipeline, and the fly ash is prone to sticking and adsorbing on the inner wall of the transport pipeline after getting damp, resulting in blockage of the transport pipeline. It is necessary to check a relatively long transport pipeline to unclog it, which affects the fly ash granulation speed. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. When this application is in use, the low-temperature airflow collides with the high-temperature flue gas. The low-temperature airflow carries a small amount of low-temperature liquid. Condensation occurs to the high-temperature flue gas, and the dust in the high-temperature flue gas aggregates into large particles. The high temperature of the high-temperature flue gas itself is used to condense the dust into large-particle dust. The flue gas needs to pass through the second filter member and then enter the interior of the equipment housing through the ash inlet chute. The flue gas passes through the small holes and the first filter member and then enters the conveying pipe. While the second filter member intercepts the large particles in the flue gas, the temperature of the flue gas discharged into the interior of the conveying pipe is cooled once. During the process of intercepting and collecting the dust in the flue gas by the granulation equipment in this application, the high-temperature flue gas is cooled, reducing dust pollution and heat pollution. Moreover, the low-temperature airflow carries a small amount of low-temperature liquid. During the process of the high-temperature flue gas colliding with the low-temperature airflow to aggregate large particles, a liquid that plays an adhesive role is pre-modulated and combined with the dust, completing the work of adding an adhesive to the dust. The granulation pretreatment work is completed while collecting the dust in the flue gas, and there is no need to convey the dust after collection, ensuring the quality of dust collection and granulation.

[0017] 2. When this application is in use, after the air extraction pump extracts air from the interior of the conveying pipe through the third air guide pipe and the first solenoid valve, the gas is conveyed to the interior of the second shunt box at the bottom of the inner cavity of the first cooling box through the second air guide pipe, for secondary cooling of the flue gas. The low-temperature liquid in the second cooling box enters the interior of the third shunt box through the fourth solenoid valve and the first diversion pipe. The third shunt box with multiple round holes three sprinkles the liquid to multiple positions inside the first cooling box, ensuring that there is a certain level of low-temperature liquid inside the first cooling box, which can ensure the cooling effect of the airflow and flue gas, and fully and evenly mix a certain amount of liquid with an adhesive function into the dust particles, ensuring the success rate of dust granulation.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] Embodiment: As Figures 1 - 13As shown in the figure, the present invention provides a technical solution for a forming granulation device for preparing fuel particles from solid waste, including an equipment installation box 1. Inside the equipment installation box 1, there is a material receiving and granulation structure. The material receiving and granulation structure includes an equipment housing 2 rotatably arranged inside the equipment installation box 1, a reciprocating lead screw 6 rotatably inserted on the equipment housing 2, and a granulation driving component installed outside the reciprocating lead screw 6. The top of the equipment housing 2 is connected to a dust treatment structure. The dust treatment structure includes a dust recovery frame 23 connected to the equipment housing 2, a baffle component rotatably arranged inside the dust recovery frame 23, a first cooling box 37 connected to one side of the dust recovery frame 23, and a circulating air supply component installed outside the first cooling box 37.

[0022] Specifically, as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 shown, an electromagnet component 4 and a plurality of first mounting frames 3 are rotatably installed outside the equipment housing 2. The electromagnet component 4 and the plurality of first mounting frames 3 are both fixedly installed inside the equipment installation box 1. The equipment housing 2 can rotate on its own inside the equipment installation box 1. One end of the equipment housing 2 away from the granulation driving component is rotatably connected to a mounting box 16. The mounting box 16 is fixedly installed at one end of the equipment installation box 1 and cannot move. Inside the mounting box 16, a first filter member 18 is rotatably installed. The first filter member 18 can rotate inside the mounting box 16. The first filter member 18 can rotate synchronously with the equipment housing 2. A plurality of small holes 21 are provided on one side of the first filter member 18 and one side of the mounting box 16.

[0023] A plurality of card slots 17 are provided inside the mounting box 16. A clamping plate 19 arranged inside the card slots 17 is fixedly connected to the first filter member 18. One end of the reciprocating lead screw 6 passes through the mounting box 16 and extends to the outside of the equipment installation box 1. A plurality of blades 15 fixedly installed outside one end of the reciprocating lead screw 6 are all arranged outside the equipment installation box 1. The blades 15 rotate synchronously with the reciprocating lead screw 6. The reciprocating lead screw 6 is rotatably connected to the mounting box 16. The rotation of the reciprocating lead screw 6 is not affected by the mounting box 16. A magnet member 20 is fixedly installed inside the first filter member 18. The magnet member 20 is rotatably sleeved outside the reciprocating lead screw 6. The magnet member 20 is adsorbed and fixed to the reciprocating lead screw 6 by magnetic force.

[0024] The output end of the forward and reverse motor 5 is fixedly connected to the reciprocating lead screw 6. When the forward and reverse motor 5 rotates forward to drive the reciprocating lead screw 6 to rotate clockwise, the reciprocating lead screw 6 drives the first filter member 18 to rotate clockwise through the magnet member 20. The first filter member 18 drives the clamping plate 19 to rotate clockwise inside the card slot 17. The shape of the card slot 17 is pre-calculated and designed. When the clamping plate 19 rotates and abuts against the installation box 16, the rotation of the first filter member 18 is restricted, the magnet member 20 is restricted, and the reciprocating lead screw 6 continues to rotate while the first filter member 18 cannot rotate. At this time, the small holes 21 opened on the first filter member 18 are aligned with the multiple small holes 21 opened on the installation box 16, and the equipment housing 2 enters the granulation state.

[0025] When the forward and reverse motor 5 rotates reversely to drive the reciprocating lead screw 6 to rotate counterclockwise, the reciprocating lead screw 6 drives the first filter member 18 to rotate counterclockwise through the magnet member 20. When the clamping plate 19 abuts against the installation box 16, the rotation of the first filter member 18 stops. The small holes 21 opened on the first filter member 18 are staggered from the multiple small holes 21 opened on the installation box 16, and the equipment housing 2 enters the material storage state.

[0026] Specifically, as Figure 1 、 Figure 2 and Figure 3 shown, a blower 45 is arranged outside the equipment installation box 1. The air outlet end of the blower 45 is fixedly installed with a delivery pipe 44. The delivery pipe 44 is arranged on one side of the installation box 16. A plurality of blades 15 are arranged inside the delivery pipe 44. The particulate matter cut by the rotating blades 15 falls into the delivery pipe 44. The working blower 45 conveys air flow into the delivery pipe 44, and the air flow conveys and dries the particulate matter to complete the particulate matter cleaning work.

[0027] A third filter member 46 is fixedly installed on the top of the delivery pipe 44. The setting of the third filter member 46 makes the inside of the delivery pipe 44 communicate with the outside. A second solenoid valve 47 is arranged on the top of the third filter member 46. By controlling the second solenoid valve 47 fixedly installed on the top of the delivery pipe 44 to work, the delivery pipe 44 can be communicated with the outside.

[0028] Specifically, as Figure 1 、 Figure 5 and Figure 6 shown, in the granulation drive assembly, the forward and reverse motor 5 is fixedly installed at one 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 lead screw 6. The inner ring of the one-way bearing 9 is fixedly installed on the outside of the reciprocating lead screw 6. A first gear 7 is fixedly installed on the outside of the outer ring of the one-way bearing 9. An installation shaft 10 is fixedly installed inside the second gear 8 meshing with the first gear 7. The installation shaft 10 is fixedly connected to the equipment installation box 1. The installation shaft 10 supports the second gear 8 to enable the second gear 8 to only rotate self. The internal gear ring 11 meshing with the outside of the second gear 8 is fixedly connected to the equipment housing 2.

[0029] When the forward and reverse motor 5 rotates in reverse, the equipment housing 2 is in the material storage state. At this time, the rotation direction of the reciprocating lead screw 6 is the self-locking direction between the inner and outer rings of the one-way bearing 9. At this time, the rotation of the reciprocating lead screw 6 drives the equipment housing 2 to rotate through structures such as the one-way bearing 9, the first gear 7, the second gear 8, and the internal gear ring 11. The rotating equipment housing 2 plays a role in mixing the internally stored materials, avoiding the situation that the materials inside the equipment housing 2 agglomerate and affect the granulation quality.

[0030] A one-way bearing 12 is installed outside the reciprocating lead screw 6 through a nut pair. The outer ring of the one-way bearing 12 is fixedly connected to the ring 13. Both the one-way bearing 12 and the ring 13 are arranged on one side inside the equipment housing 2. One end of the two support shafts 14 passing 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 lead screw 6 cannot directly drive the ring 13 to rotate. When the forward and reverse motor 5 rotates in reverse and the equipment housing 2 is in the material storage state, the rotation direction of the reciprocating lead screw 6 is the self-rotation direction between the inner and outer rings of the one-way bearing 12, and the position of the ring 13 remains unchanged.

[0031] When the forward and reverse motor 5 rotates forward, the equipment housing 2 is in the granulation state. At this time, the rotation direction of the reciprocating lead screw 6 is the self-rotation direction between the inner and outer rings of the one-way bearing 9. The rotation of the reciprocating lead screw 6 will not apply force to the equipment housing 2. At this time, the electromagnet 4 works to adsorb and fix the equipment housing 2 through magnetic force. The position of the equipment housing 2 is restricted. At this time, the rotation direction of the reciprocating lead screw 6 is the self-locking direction between the inner and outer rings of the one-way bearing 12. The reciprocating lead screw 6 drives the one-way bearing 12 and the ring 13 to perform reciprocating motion inside the equipment housing 2, applying a thrust to the dust inside the equipment housing 2.

[0032] Specifically, as Figure 2 、 Figure 8 、 Figure 10 、 Figure 12 and Figure 13 shown, the solenoid valve 43 in the circulating air supply assembly is fixedly installed on one side of the conveying pipe 44. One end of the air guide pipe 42 fixedly installed on one side of the solenoid valve 43 is fixedly connected to the first impeller box 41. The air guide pipe 40 fixedly connected between the first impeller box 41 and the bottom of the first cooling box 37. A plurality of round holes 39 are opened at the top of the second flow distribution box 38 provided at the top of the air guide pipe 40. The second flow distribution box 38 is fixedly installed at the bottom of the inner cavity of the first cooling box 37. The second flow distribution box 38 with a plurality of round holes 39 has the effect of evenly distributing the air flow conveyed by the air guide pipe 40 to each position at the bottom of the inner cavity of the first cooling box 37.

[0033] A driving motor 48 is fixedly installed on one side of the cooling box 37, an impeller box 2 51 is provided on one side of the impeller box 41, an impeller 1 50 is rotatably installed inside the impeller box 41, and an 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, and the long shaft 49 passes through the impeller 1 50 and the impeller 2 52 and is fixedly connected to the impeller 1 50 and the impeller 2 52. When the driving motor 48 drives the long shaft 49 to rotate, the long shaft 49 drives the impeller 1 50 and the impeller 2 52 to rotate.

[0034] 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 airflow 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.

[0035] Furthermore, because a diversion box 32 is fixedly installed on the top of both sides of the dust recovery rack 23, a plurality of circular holes 33 are opened on the side of the diversion box 32 facing the dust recovery rack 23, and the plurality of 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 smoke into the dust recovery rack 23, and one side of the other diversion box 32 is fixedly installed with a one-way valve 35, and an air guide duct 36 is fixedly connected between the one-way valve 35 and the top of the cooling box 37; therefore, the airflow transported to the cooling box 37 through the air guide duct 40 enters the dust recovery rack 23 through the air guide duct 36, the one-way valve 35 and the diversion box 32; the solenoid valve 47 is in a normally open state, which meets the need for exhaust and pressure relief from the inside of the delivery pipe 44.

[0036] 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 acts to prevent the liquid inside the cooling box 2 54 from flowing back into the impeller box 2 51. A guide pipe 2 61 is fixedly installed at the water inlet end of the water pump, and one end of the guide pipe 2 61 extends to 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 draws liquid from the cooling box 1 37 through the guide pipe 2 61 and transports it to 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.

[0037] Inside the cooling box two 54, a solenoid valve four 57 is fixedly installed. Between the solenoid valve four 57 and the shunt box three 59, a diversion pipeline one 58 is fixedly installed. On one side of the shunt box three 59, a plurality of round holes three 60 are provided. The plurality of round holes three 60 divert the liquid entering the inside of the shunt box three 59, causing the liquid to be scattered to multiple positions inside the cooling box one 37. On both sides of the cooling box two 54, a plurality of peltier elements 56 are fixedly penetrated. The cooling ends of the peltier elements 56 are arranged inside the cooling box two 54 to cool the liquid inside the cooling box two 54. On the top of the cooling box two 54, a solenoid valve three 55 is fixedly installed. After the solenoid valve three 55 works and opens, liquid can be replenished into the cooling box two 54.

[0038] Specifically, as Figure 8 , Figure 9 and Figure 11 shown, in the baffle component, the mounting frame two 22 is fixedly installed at the bottom of the dust recovery frame 23. The mounting frame two 22 is rotatably installed on the outside of the equipment housing 2. And on the outside of the mounting frame two 22 and the outside of the equipment housing 2, dust inlet grooves 24 are provided. When the dust inlet groove 24 opened by the mounting frame two 22 aligns with the dust inlet groove 24 opened by the equipment housing 2, the inside of the equipment housing 2 is communicated with the inside of the dust recovery frame 23.

[0039] Inside the dust recovery frame 23, a mounting frame three 25 is rotatably penetrated. A plurality of filter components two 26 are fixedly installed on the outside of the mounting frame three 25. On the outside of one end of the mounting frame three 25 located outside the dust recovery frame 23, a brake 28 is sleeved. The housing of the brake 28 is fixedly connected to the dust recovery frame 23. When controlling the brake 28 to work, the brake 28 brakes and limits the mounting frame three 25, and the mounting frame three 25 cannot rotate.

[0040] The forming and granulating equipment is composed of structures such as the equipment installation box 1, the material receiving and granulating structure, the dust treatment structure, the blower 45, the conveying pipe 44, etc. Connecting a human-computer interaction device to control the forming and granulating equipment to work is the prior art and will not be elaborated here.

[0041] The working principle of the forming and granulating equipment is as follows: Control the forming and granulating equipment to work and enter the initial state. The initial state is that after the equipment housing 2 enters the material storage state, the dust inlet groove 24 opened by the equipment housing 2 aligns with the dust inlet groove 24 opened by the mounting frame two 22. The forward and reverse motor 5 stops working, and the electromagnet component 4 works to limit the position of the equipment housing 2.

[0042] Subsequently, flue gas is discharged into the interior of the dust recovery rack 23 through the exhaust pipe 34 and the first shunt box 32 fixedly installed on the exhaust pipe 34. At the same time, the driving motor 48 is controlled to operate, and the air extraction pump conveys air flow into the interior of the dust recovery rack 23 through the first cooling box 37, the first air guide pipe 36, the first one-way valve 35, and the first shunt box 32 fixed with the first one-way valve 35. The first shunt box 32 provided with a plurality of first round holes 33 plays a role in dispersing and guiding the gas, so the air flow and the flue gas collide after being spread out; and the air flow passing through the interior of the first cooling box 37 is dispersed by the second shunt box 38 provided with a plurality of second round holes 39 and then moves upward. During the upward movement of the air flow, it passes through the low-temperature liquid stored in the interior of the first cooling box 37; therefore, the low-temperature air flow collides with the high-temperature flue gas. The low-temperature air flow carries a small amount of low-temperature liquid, and the high-temperature flue gas undergoes a condensation phenomenon. The dust in the high-temperature flue gas coagulates with each other into large particles. The high temperature of the high-temperature flue gas itself is used to condense the dust into large-particle dust. The flue gas needs to pass through the second filter element 26 and then enter the equipment housing 2 through the ash inlet chute 24. The flue gas passes through the small holes 21 and the first filter element 18 and then enters the conveying pipe 44. While the second filter element 26 intercepts the large particles in the flue gas, the temperature of the flue gas discharged into the interior of the conveying pipe 44 is cooled once. In the present application, during the process of intercepting and collecting the dust in the flue gas by the forming and granulating equipment, the high-temperature flue gas is cooled, reducing dust pollution and heat pollution. Moreover, the low-temperature air flow carries a small amount of low-temperature liquid. During the process of the high-temperature flue gas colliding with the low-temperature air flow to form large particles, the liquid pre-modulated to play an adhesive role is combined with the dust, completing the work of adding an adhesive to the dust, and completing the granulation pretreatment work while collecting the dust in the flue gas, without the need to convey the dust after collection, ensuring the quality of dust collection and granulation.

[0043] After the air extraction pump extracts air from the interior of the conveying pipe 44 through the third air guide pipe 42 and the first solenoid valve 43, the gas is conveyed through the second air guide pipe 40 into the interior of the second shunt box 38 at the bottom of the inner cavity of the first cooling box 37 to cool the flue gas for the second time. After the forming and granulating equipment works for a period of time, the air extraction pump extracts the flue gas after the first cooling and conveys it into the interior of the first cooling box 37. The water extraction pump extracts the liquid from the interior of the first cooling box 37 through the second diversion pipe 61 and then conveys it into the interior of the second cooling box 54 through the second impeller 52. The high-speed flowing liquid stirs the liquid in the interior of the second cooling box 54, enabling the liquid in the interior of the second cooling box 54 to be cooled at a high speed. A first diversion pipe 58 is fixedly installed between the fourth solenoid valve 57 and the third shunt box 59. Therefore, the low-temperature liquid in the interior of the second cooling box 54 enters the interior of the third shunt box 59 through the fourth solenoid valve 57 and the first diversion pipe 58. The third shunt box 59 provided with a plurality of third round holes 60 sprinkles the liquid to multiple positions in the interior of the first cooling box 37, ensuring that there is a certain level of low-temperature liquid in the interior of the first cooling box 37, which can ensure the cooling effect of the air flow and the flue gas, and fully and evenly mix a fixed amount of liquid with an adhesive effect into the dust particles, ensuring the success rate of dust granulation.

[0044] After the flue gas is supplied for a period of time, control the brake 28 to stop working for a period of time and then work again, so that the mounting bracket three 25 loses its limit for a period of time. At this time, several filter elements two 26 at the top intercept a large amount of dust particles. The weight on the top and bottom of the outer side of the mounting bracket three 25 is unbalanced. Coupled with the airflow moving towards the inside of the equipment housing 2 exerting a thrust on the filter elements two 26, part of the filter elements two 26 that have intercepted a large amount of dust drive the mounting bracket three 25 to rotate. The filter elements two 26 that have intercepted dust rotate to the bottom, and the intercepted dust enters the inside of the equipment housing 2 through the ash inlet groove 24 for storage. Moreover, after the flue gas collides with the low-temperature gas, it passes through multiple filter elements two 26. The speed of the flue gas is not enough to push the dust inside the equipment housing 2 towards the mounting box 16. And after the rotation and displacement, the side of the filter element two 26 that intercepts dust is in the front of the advancing direction of the flue gas, and the filter element two 26 is flushed and dredged by the flue gas airflow; it can make multiple filter elements two 26 work alternately, reduce the possibility of blockage of the filter elements two 26, ensure the dust interception effect, and ensure the smooth flow of the flue gas at the same time.

[0045] And regularly control the electromagnet part 4 to pause working for a period of time and then work again. During this process, the positive and negative motor 5 reversely works to drive the equipment housing 2 to rotate multiple times. After the positive and negative motor 5 stops working, the equipment housing 2 resumes the communication state with the inside of the dust recovery frame 23. During the rotation of the equipment housing 2, the dust stored inside the equipment housing 2 is thrown up and then falls, achieving a material mixing effect, making the amount of dust at each position inside the equipment housing 2 roughly the same, and providing space for the dust intercepted inside the dust recovery frame 23 to enter the inside of the equipment housing 2.

[0046] At the end of a period of flue gas supply, control the solenoid valve four 57 to work and close, and the liquid inside the cooling box two 54 no longer moves towards the inside of the cooling box one 37. The working water pump transports most of the liquid inside the cooling box one 37 to the inside of the cooling box two 54. Multiple filter elements two 26 and filter elements one 18 filter and intercept the dust in the flue gas until the liquid inside the cooling box one 37 is used up, then stop the flue gas supply. Subsequently, control the electromagnet part 4 to pause working, control the positive and negative motor 5 to reversely work to drive the equipment housing 2 to rotate multiple times to mix the dust inside the equipment housing 2, and after the positive and negative motor 5 finishes working, control the electromagnet part 4 to work to limit the position of the equipment housing 2.

[0047] Finally, control the forward and reverse motor 5 to rotate forward, and the equipment housing 2 enters the granulation state. The small holes 21 opened in the first filter member 18 are 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 two 12 and the ring 13 move towards the installation box 16. The dust is under a certain pressure and enters the inside of the conveying pipe 44 after being shaped through the small holes 21. The rotating reciprocating screw rod 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 a granular shape. At the same time, control the solenoid valve two 47 to work and close, and the blower 45 conveys air flow into the inside of the conveying pipe 44 to convey the dust particles to a preset position for collection, completing the granulation work.

[0048] In addition, as Figure 7 shown, a humidity sensor is fixedly installed at the bottom on one side where the installation box 16 is arranged inside the equipment housing 2 to detect the humidity of the dust inside the equipment housing 2. Before the granulation work is carried out, when the dust humidity is too high, control the forward and reverse motor 5 to rotate in reverse to drive the equipment housing 2 to rotate. The dust inside the equipment housing 2 moves, and at the same time, smoke is infused into the dust recovery frame 23. The high-temperature smoke dries the dust during the flow inside the equipment housing 2. The forward and reverse motor 5 pauses working once every once in a while, and it is judged whether the forward and reverse motor 5 continues to work according to the dust humidity inside the equipment housing 2.

[0049] When the dust humidity inside the equipment housing 2 is too low, control the solenoid valve four 57 to work and open, supplement liquid into the first cooling box 37, control the drive motor 48 to work, supplement humid air flow into the equipment housing 2 to humidify the dust, and the forward and reverse motor 5 rotates in reverse to drive the equipment housing 2 to rotate. The dust inside the equipment housing 2 moves. The forward and reverse motor 5 pauses working once every once in a while, and it is judged whether the forward and reverse motor 5 continues to work according to the dust humidity inside the equipment housing 2.

[0050] When the dust humidity inside the equipment housing 2 is within the preset range, the granulation work is carried out.

[0051] In addition, as Figure 11As shown, a first groove 27 is provided between two adjacent second filter net members 26. The first groove 27 is formed on the outer side of the third mounting bracket 25. A sampling rod 30 is inserted into the third mounting bracket 25, and the third mounting bracket 25 and the sampling rod 30 are in an interference fit state. A second groove 31 is formed on the outer side of the sampling rod 30, and the second groove 31 is aligned with one of the first grooves 27. After controlling the brake 28 to stop working, the third mounting bracket 25 is manually rotated. The third mounting bracket 25 and the sampling rod 30 rotate to throw out the dust inside the second groove 31. After a period of time, the third mounting bracket 25 is rotated to align the pointing plate 29 fixedly installed on the outer side of the sampling rod 30 with a preset mark on the brake 28. Then, the brake 28 is controlled to work. At this time, the first groove 27 faces the top of the inner cavity of the dust recovery frame 23, and large particles formed by the aggregation of dust in some high-temperature flue gas fall into the second groove 31. After a period of time, after restricting the third mounting bracket 25, the brake 28 is controlled to stop working, and most of the sampling rod 30 is pulled to the outer side of the third mounting bracket 25. By observing the number of large particles inside the second groove 31, data can be collected to determine whether the forming and granulating equipment is working properly.
