Description

Technical Field

[0001] This invention relates to the field of solid waste treatment technology, and more specifically, to a device for the harmless treatment of organic solid waste. Background Technology

[0002] Food waste mainly includes leftover food, fruit and vegetable scraps, meat residues, and waste oil generated during catering processing, food consumption, and canteen meals. This type of waste typically has high moisture content, high oil content, is easily perishable and smelly, and exhibits significant variations in composition and particle size. Direct incineration would result in excessive heat consumption due to the high moisture content, leading to fluctuating furnace temperatures, incomplete combustion, and increased auxiliary fuel consumption. Therefore, before using food waste for incineration, it usually needs to be crushed, dehydrated by compression, and dried to reduce moisture content and improve combustion conditions.

[0003] Existing food waste processing equipment typically first reduces the size of the material through a crushing mechanism, and then uses screw extrusion or other pressing methods to separate the liquid from the material. However, after being extruded and dehydrated, food waste easily forms compacted lumps or clumps with few internal pores, making it difficult for hot air to penetrate fully. If hot air is only introduced from the surface of the material, the outer layer may dry while the interior retains a high moisture content, resulting in uneven drying. Compacted material is also prone to accumulating, bridging, or moving as a whole with the conveyor mechanism in the drying chamber, making it difficult to fully disperse within the limited processing space, thus affecting subsequent conveying and incineration.

[0016] The beneficial effects of this invention are: 1. In this invention, during the rotation of the rotating rod, the inner stirring blades first disperse the compressed clumps of material discharged from the circumference of the push plate and push the material towards the area of ​​the air outlet ring. The compressed hot air ejected from the air outlet ring then blows and heats the dispersed material. After the material falls to the bottom of the processing chamber, it is lifted upward by the outer stirring blades and dispersed into the area of ​​hot air action under the action of gravity. Through the above continuous cycle, the material after extrusion and dehydration is continuously dispersed, turned over, and fully contacted with the compressed hot air, reducing material clumping and local accumulation, improving drying uniformity, thereby reducing the moisture content of the material and improving its looseness, facilitating subsequent transportation and incineration.

[0017] 2. This invention uses a motor assembly to drive the air-blocking ring to rotate relative to the air-exiting ring, reducing the number of air outlets in an effective air-exiting state at any given time. This allows compressed hot gas to be concentrated and ejected through the corresponding air outlets, increasing the local purging intensity. As the air-blocking ring continues to rotate, air outlets at different positions can be sequentially and concentratedly purged, thereby removing or loosening grease, dust, and fine materials adhering to the orifice walls and openings, delaying air outlet blockage. This process can be completed during device operation at preset time intervals without requiring shutdown for cleaning, which helps maintain a stable output of compressed hot gas and improves the reliability of continuous device operation.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0022] Example, refer to Figures 1-4 The device includes a frame 1, on which a mixing chamber 2, a first power assembly 3, and a second power assembly 4 are fixedly connected. The first power assembly 3 is equipped with a crushing assembly for crushing the organic solid waste entering the device. The second power assembly 4 is equipped with a compression assembly for compressing and dehydrating the crushed organic solid waste. The compression assembly is equipped with a premixed drying assembly for drying and fluffing the compressed solid waste. The mixing chamber 2 is used to further stir, homogenize, and dry the premixed and dried solid waste, and to transport the processed solid waste outward. The premixed drying assembly includes a processing chamber 6 set on the compression assembly. An air outlet ring 68 is set inside the processing chamber 6. A ring support 9 is set on the inner side of the air outlet ring 68. An air blocking ring 8 is embedded in the ring support 9.

[0023] A discharge pipe 21 is located at the bottom of the mixing chamber 2, on the side of the mixing chamber 2 away from the processing chamber 6. A screw feed shaft is installed inside the discharge pipe 21, which, when rotated, transports the processed solid waste from the mixing chamber 2 outwards. The discharge pipe 21 is connected to the mixing chamber 2, which is rotatably connected to a stirring shaft 22. Multiple stirring rods 23 are fixedly connected to the stirring shaft 22, rotating with it to agitate the solid waste entering the mixing chamber 2, thus dispersing and mixing the solid waste and allowing the hot air entering the mixing chamber 2 from the processing chamber 6 to further contact the solid waste. An exhaust port 24 is provided on the mixing chamber 2, through which the humid exhaust gas generated during the solid waste drying process is discharged and enters an external exhaust gas treatment system.

[0024] The crushing assembly includes a crushing shell 31 fixedly connected to a frame 1. A set of crushing wheels is installed inside the crushing shell 31. The output shaft of the first power assembly 3 is drively connected to one shaft of the crushing wheels to drive the crushing wheels to crush the organic solid waste entering the crushing shell 31. A hopper 32 is fixedly connected to the top of the crushing shell 31. A spiral pusher shaft 33 is rotatably installed inside the hopper 32 to convey the organic solid waste fed into the hopper 32 to the crushing shell 31. The hopper 32 is connected to the crushing shell 31. When the crushing wheels rotate relative to each other, they compress, shear, and tear the organic solid waste, turning larger solid waste into smaller fragments, providing conditions for subsequent extrusion dehydration and hot air drying.

[0025] The output end of the second power assembly 4 is equipped with a rotating rod 41. The extrusion assembly includes a receiving shell 5 fixedly connected to the frame 1. The receiving shell 5 is arranged in an inclined tubular shape and is connected to the crushing shell 31. A waste liquid pipe 51 is fixedly connected to the bottom end of the receiving shell 5. A filter cylinder 52 is fixedly connected inside the receiving shell 5. The liquid discharged from the filter cylinder 52 can be collected inside the receiving shell 5 and discharged outward through the waste liquid pipe 51. The rotating rod 41 extends into the filter cylinder 52 through the end of the receiving shell 5 and the filter cylinder 52. A first spiral blade 53 is fixedly wound on the rotating rod 41. The first spiral blade 53 can push the crushed organic solid waste along the filter cylinder 52 and extrude water from the material. The ends of the filter cartridge 52 and the housing 5 are fixedly connected to the side wall of the processing chamber 6. A fixing ring 54 is fixedly sleeved on the rotating rod 41. A push plate 56 is slidably arranged on the rotating rod 41. A push spring 55 is fixedly connected to the end of the fixing ring 54. The end of the push spring 55 abuts against the end of the push plate 56. The push plate 56 is located inside the processing chamber 6. The push plate 56 presses against the inner side wall of the processing chamber 6 by the pushing force of the push spring 55 to seal the end of the filter cartridge 52. One end of the push spring 55 is connected to or abuts against the fixing ring 54, and the other end abuts against the push plate 56 to keep the push plate 56 exerting a force toward the end of the filter cartridge 52, thereby elastically sealing the end of the filter cartridge 52.

[0026] Reference Figures 4-8The processing chamber 6 is tubular. A sealing plate 63 is fixedly connected to the end of the processing chamber 6 away from the filter cartridge 52. A motor assembly 61 is fixedly connected to the side wall of the sealing plate 63. The output end of the motor assembly 61 extends through the sealing plate 63 into the inside of the processing chamber 6. A conveying pipe 7 is fixedly connected to the side wall of the sealing plate 63. The end of the conveying pipe 7 is fixedly connected to the side wall of the mixing box 2. The top of the mixing box 2 is sealed. The conveying pipe 7 communicates with the interior of the mixing box 2. An mounting plate 71 is fixedly connected to the inner side wall of the conveying pipe 7. The mounting plate 71 is rotatably connected to the rotating rod 41. The mounting plate 71 is used to provide rotational support for the end of the rotating rod 41 away from the second power assembly 4. A connector 72 is provided at the end of the rotating rod 41. The connector 72 is connected to the external air supply assembly through a high-temperature resistant rotary joint. The external air supply assembly includes an air compression mechanism and a heat exchange mechanism. The air compression mechanism is used to provide gas with a certain pressure, and the heat exchange mechanism is used to heat the compressed gas using the waste heat of the boiler, and then transport the heated high-temperature compressed gas to the rotating rod 41 through the high-temperature resistant rotary joint and connector 72.

[0027] A second helical blade 62 is fixedly wound around the side wall of the rotating rod 41 inside the conveying pipe 7. The pitch of the second helical blade 62 is greater than that of the first helical blade 53. The larger pitch is beneficial to enable the second helical blade 62 to form a relatively large material conveying capacity, thereby timely conveying the dispersed and preheated solid waste in the processing chamber 6 to the mixing box 2. The end of the second helical blade 62 extends into the inner side of the processing chamber 6. The premixed drying assembly includes a fixed seat 64 fixedly sleeved on the rotating rod 41. Multiple circumferentially arranged connecting pipes 65 are fixedly connected to the side wall of the fixed seat 64. Connecting seats 66 are fixedly connected to the connecting pipes 65. An inner stirring plate 67 is fixedly connected to the side wall of the connecting seat 66. The inner stirring plate 67 is bent. The bent end of the inner stirring plate 67 is close to the circumferential contour of the push plate 56. When the solid waste after squeezing and dehydration enters the processing chamber 6 through the annular gap around the push plate 56, the inner stirring plate 67 can promptly agitate the material that has just entered the processing chamber 6, reducing the continued agglomeration of the squeezed material near the push plate 56. The bent end of the inner stirring blade 67 bends in the direction of rotation, which can generate a component force on the material away from the push plate 56 when the material is moved, causing the material that has just entered the processing chamber 6 to move towards the hot air injection area corresponding to the air outlet ring 68. The end of the connecting pipe 65 is bent, and the bent ends of multiple connecting pipes 65 are fixedly connected to the air outlet ring 68. Both the rotating rod 41 and the air outlet ring 68 are hollow. The rotating rod 41, the connecting pipe 65 and the air outlet ring 68 are connected. Multiple air outlet holes 69 are opened in the inner ring of the air outlet ring 68. The multiple air outlet holes 69 are radially staggered in the air outlet ring 68 and evenly distributed in the circumferential direction of the air outlet ring 68 to expand the effective air outlet area and reduce the situation where hot air is concentrated on the same circumferential trajectory.

[0028] The diameter of the connecting pipe 65 is smaller than that of the exhaust ring 68. The connecting pipe 65 is connected to the outer circumference of the exhaust ring 68 to avoid the ring support 9 and the air-blocking ring 8 located inside the exhaust ring 68. A collar 681 is fixedly connected to the outer circumference of the exhaust ring 68, and multiple outer stirring blades 682 are fixedly connected to the circumference of the collar 681. The collar 681 and the outer stirring blades 682 can rotate synchronously with the exhaust ring 68 and the rotating rod 41. When the outer stirring blades 682 rotate, they can support and move the solid waste upward from the bottom of the processing chamber 6. When the material is moved to a higher position, it detaches from the outer stirring blades 682 under the action of gravity and falls downward, thereby causing the material in the processing chamber 6 to continuously undergo a cyclical motion of being lifted from bottom to top and falling from top to bottom.

[0029] Reference Figures 8-13 The cross-section of the air-blocking ring 8 is arc-shaped. The air-blocking ring 8 is located inside the air-outlet ring 68. Multiple equidistant gear grooves 81 are provided on the side wall of the air-blocking ring 8. Multiple air outlets 83 are provided on the air-blocking ring 8. Mounting blocks 82 are provided on the air-blocking ring 8. Both ends of the air-blocking ring 8 are provided with annular platforms 821. Bosses 822 are provided on the annular platforms 821. The mounting blocks 82 are semi-annular. The inner surface of the mounting blocks 82 is provided with mating surfaces that cooperate with the annular platforms 821 and the bosses 822. The interaction between the annular platforms 821 and the bosses 822 is used to limit the mounting blocks 82.

[0030] After the air-blocking ring 8 and the mounting block 82 are installed, a predetermined fitting gap is maintained between the opposing surfaces of the air-blocking ring 8 and the air-exhaust ring 68, so that the air-blocking ring 8 will not generate excessive frictional resistance to the air-exhaust ring 68 which rotates with the rotating rod 41. Part of the airflow ejected from the air outlet 69 can enter the fitting gap between the air-blocking ring 8 and the air-exhaust ring 68, and blow away the fine particles that enter the gap, reducing the probability of the air-blocking ring 8 getting stuck due to particle accumulation.

[0031] The ring bracket 9 is arranged in an arc shape, and the air-blocking ring 8 is sleeved on the ring bracket 9. The air-blocking ring 8 is located between the ring bracket 9 and the air outlet ring 68. The ring bracket 9 does not block the air outlet 83, which is distributed at the bottom of the air-blocking ring 8. A bracket rod 91 is fixedly connected to the ring bracket 9. Multiple positioning pins 92 are provided at the end of the bracket rod 91. The sealing plate 63 has positioning holes corresponding to the positioning pins 92. The positioning pins 92 are used to determine the initial installation position of the ring bracket 9 relative to the sealing plate 63 when the ring bracket 9 is disassembled and reinstalled, thereby improving the repeatability accuracy of the ring bracket 9 and the air-blocking ring 8. The support rod 91 is fixedly connected to the sealing plate 63. Multiple auxiliary sleeves 93 are fixedly connected to both ends of the ring support 9. The auxiliary sleeves 93 are distributed on both sides of the end of the ring support 9. An auxiliary spring 931 is provided inside the auxiliary sleeve 93. The bottom end of the auxiliary spring 931 abuts against the auxiliary pin 932. The bottom end of the auxiliary pin 932 passes through the ring support 9 and squeezes the air-blocking ring 8 by the elastic force of the auxiliary spring 931. An inclined groove 94 is provided on the surface of the end of the ring support 9 that is in contact with the air-blocking ring 8. When the air-blocking ring 8 rotates relative to the ring support 9, small particles that enter the air outlet 83 or the mating gap can enter the inclined groove 94. The inclined groove 94 provides space for the particles to be discharged outward. At the same time, the airflow ejected from the air outlet 69 carries the particles away from the inclined groove 94, reducing the probability of particles being stuck between the air-blocking ring 8 and the ring support 9.

[0032] The auxiliary spring 931 applies an elastic limiting force to the air-blocking ring 8 through the auxiliary pin 932, which is used to limit the upward movement of the air-blocking ring 8 during the driving process of the pinion 97, so that the air-blocking ring 8 is kept in the predetermined rotation position and the fitting clearance between the air-blocking ring 8 and the air-out ring 68 is maintained.

[0033] A gear cover 96 is fixedly connected to the bottom of the ring bracket 9. A small gear 97 is rotatably connected inside the gear cover 96. The gear cover 96 is used to partially shield and support the small gear 97, and does not require a completely sealed gear cavity with the external environment. The small gear 97 meshes with the gear tooth groove 81. A transmission rod 98 is provided on the small gear 97. The transmission rod 98 passes through the end of the gear cover 96 and is connected to the output shaft of the motor assembly 61. The motor assembly 61 drives the small gear 97 to rotate through the transmission rod 98. The small gear 97 drives the air-blocking ring 8 to rotate relative to the ring bracket 9 and the air outlet ring 68 through the gear tooth groove 81, thereby changing the position of the air outlet 83 relative to the air outlet hole 69 on the air outlet ring 68, and adjusting the number and distribution range of the air outlet holes 69 on the air outlet ring 68 that are in an effective air outlet state.

[0034] The working principle of this organic solid waste harmless treatment device is as follows: In use, the sorted organic solid waste, after removing unsuitable substances such as metal and glass, is first fed into the hopper 32. The spiral pusher shaft 33 rotates, continuously pushing the organic solid waste in the hopper 32 into the crushing shell 31. The first power assembly 3 drives the crushing wheel assembly to rotate relative to each other, squeezing, shearing, and tearing the organic solid waste, breaking larger pieces into smaller fragments. The crushed fragments enter the filter cylinder 52 from the crushing shell 31. The second power assembly 4 drives the rotating rod 41 and the first spiral blade 53 to rotate, and the first spiral blade 53 pushes the fragments in the filter cylinder 52 toward the treatment chamber 6. Due to the elastic sealing of the discharge end of the filter cylinder 52 by the pusher plate 56, the fragments are gradually squeezed between the first spiral blade 53 and the pusher plate 56. The liquid separated from the fragments passes through the filter cylinder 52 into the receiving shell 5 and is discharged through the waste liquid pipe 51. When the force exerted by the broken material inside the filter cylinder 52 on the push plate 56 is greater than the elastic force of the push spring 55, the push plate 56 moves away from the filter cylinder 52 along the rotating rod 41, so that an annular discharge gap is formed between the push plate 56 and the end of the filter cylinder 52.

[0035] The dehydrated solid material enters the processing chamber 6 through the annular discharge gap and is mainly distributed near the circumference of the pusher plate 56. After the material passes through, the pusher plate 56 can return to its original position towards the filter cylinder 52 under the action of the push spring 55, so that the filter cylinder 52 continues to maintain the resistance required for dehydration. At the same time, the air compression mechanism generates compressed air, and the heat exchange mechanism uses the waste heat of the boiler to heat the compressed air. The heated compressed air enters the internal air passage of the rotating rod 41 through the high-temperature resistant rotary joint and the connector 72, and then enters the outlet ring 68 through the connecting pipe 65.

[0036] Since the air-blocking ring 8 blocks most of the air outlet holes 69 on the air outlet ring 68, only the air outlet hole 69 corresponding to the air outlet 83 of the air-blocking ring 8 can form an effective air outlet. Therefore, the compressed hot gas is concentrated and ejected from the air outlet hole 69 corresponding to the bottom area of ​​the air-blocking ring 8.

[0037] When the compressed solid material enters the processing chamber 6, multiple internal stirring blades 67 rotate synchronously with the rotating rod 41. Since the bent ends of the internal stirring blades 67 are close to the circumferential contour of the push plate 56, they can promptly agitate the material discharged from the annular discharge gap, causing the material to gradually disperse from a compressed or agglomerated state.

[0038] The inner stirring blades 67, bent along the direction of rotation, exert a component force on the material away from the push plate 56 while moving it, causing the material to move towards the concentrated air outlet area of ​​the air outlet ring 68. The compressed hot air acts on the dispersed material, causing the material to quickly absorb heat and evaporate some of the moisture inside and on the surface of the material.

[0039] The outer stirring blade 682 rotates synchronously with the exhaust ring 68. Material falling into the bottom of the processing chamber 6 is supported and driven upwards by the outer stirring blade 682. Once the material is lifted to a higher position, it detaches from the outer stirring blade 682 under gravity and falls downwards. During this repeated lifting and falling process, the material gradually forms a looser state. As the material falls, temporary gaps are formed between the material particles, allowing the compressed hot air to make more thorough contact with the material, thereby improving the preheating and drying uniformity of the material.

[0040] As the outer agitator 682 continues to rotate, the material at the bottom of the processing chamber 6 is continuously lifted upwards, periodically creating a relatively loose area in the lower part of the processing chamber 6. The material located above this loose area moves downwards under the influence of gravity, while the inner agitator 67 simultaneously pushes newly entering material near the pusher plate 56 away from the pusher plate 56, causing the newly entering, wetter material to gradually move towards the hot air injection area, reducing the possibility of the wetter material directly entering the conveying pipe 7.

[0041] Once the material in the processing chamber 6 gradually accumulates to the height of the feed end of the second spiral blade 62, the second spiral blade 62 can continuously pick up the material and convey it to the conveying pipe 7. By setting up this temporary storage area, the relatively wet material that has just been discharged from the filter cartridge 52 is less likely to immediately enter the conveying pipe 7, thereby extending the time for the material to be dried by hot air and mechanically loosened in the processing chamber 6. The pitch of the second spiral blade 62 is greater than that of the first spiral blade 53, giving the second spiral blade 62 a greater material guiding capacity, which helps to prevent the excessive accumulation of dried and loosened material in the processing chamber 6.

[0042] After premixing and drying, the solid material enters the mixing chamber 2 along the conveying pipe 7 under the action of the second spiral blade 62. Some of the hot air in the processing chamber 6 and the water vapor formed by the evaporation of the material also enter the mixing chamber 2 along with the material through the conveying pipe 7. The stirring shaft 22 drives multiple stirring rods 23 to rotate, further agitating, dispersing, and homogenizing the solid material entering the mixing chamber 2. While the material is agitated in the mixing chamber 2, it continues to be in contact with the hot air, allowing the remaining moisture inside the material to continue evaporating and mixing materials with different degrees of dryness, reducing the excessive difference in moisture content and looseness of the discharged material. The stirring rods 23 also push the material accumulating below the conveying pipe 7 towards the discharge pipe 21. The solid material that has reached the predetermined processing state enters the discharge pipe 21 and is conveyed outward by the spiral feeder shaft within the discharge pipe 21. Solid materials discharged from discharge pipe 21 can be transported to an external incineration system. Depending on the material's moisture content, calorific value, and the incinerator's operating conditions, they can be sent to the incinerator alone or mixed with other combustible solid wastes for incineration. After the aforementioned crushing, extrusion dehydration, hot gas drying, and agitation loosening processes, the moisture content of the solid materials can be reduced and their looseness improved, facilitating subsequent transportation and incineration.

[0043] The humid waste gas generated in the treatment chamber 6 and mixing chamber 2 is discharged through the exhaust port 24. The humid waste gas can be successively treated by dust removal, condensation and water removal, gas-liquid separation and demisting. The separated condensate enters the external wastewater treatment system, and the treated gas is sent into the combustion air duct of the incinerator by the induced draft mechanism, and undergoes oxidation treatment in the high-temperature combustion zone of the incinerator.

[0044] During continuous operation of the device, the motor assembly 61 drives the pinion 97 to rotate at preset time intervals, and through the gear tooth groove 81 drives the air-blocking ring 8 to rotate relative to the air-outlet ring 68, causing the air-blocking ring 8 to rotate to the position shown in the image. Figure 13 The concentrated purging position is shown. At this time, most of the air outlets 83 on the air-blocking ring 8 are moved into the shielding area of ​​the ring bracket 9, and only a small number of air outlets 83 are left to communicate with the air outlet holes 69 on the air outlet ring 68, so that the number of air outlet holes 69 in the effective air outlet state at the same time is reduced.

[0045] When the external air supply component continuously supplies air, the compressed hot air is concentrated and ejected from a small number of air outlets 69, thereby increasing the local airflow velocity and purging intensity at the corresponding air outlets 69, and purging the grease, fine materials and dust that gradually adhere to the walls and openings of the air outlets 69.

[0046] As the air-blocking ring 8 continues to rotate, the air outlets 69 at different positions on the circumference of the air outlet ring 68 correspond sequentially to the air outlet 83, thus receiving concentrated purging in sequence. After the air-blocking ring 8 completes one rotation, it returns to the normal air outlet position, so that more of the air outlets 69 are back in an effective air outlet state.

[0047] By sequentially and centrally purging multiple vents 69 at preset time intervals, adhering substances can be promptly blown away or loosened before severe blockage occurs, delaying the continuous accumulation of grease and material particles within the vents 69. During the purging process, the external air supply component maintains air supply, and compressed hot air continues to flow into the processing chamber 6. Furthermore, the time required for the air-blocking ring 8 to complete one rotation is relatively short. Therefore, online maintenance of the vents 69 can be completed without stopping material conveying and drying operations, making it suitable for long-term continuous operation of the device.

[0048] It should be noted that the specific model and specifications of the motor need to be selected and determined based on the actual specifications of the device. The specific selection and calculation method adopts the existing technology in this field, so it will not be described in detail here.

Various modifications and variations can be made to the invention by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the invention should be included within the scope of protection of the invention.
