Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments of the present application. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without making any creative effort fall into the scope of protection of the present application.

[0024] In the description of the present application, unless explicitly defined and limited otherwise, the terms “connected”, “connected”, “fixed” should be understood broadly, for example, can be fixedly connected, or can be detachably connected, or can be integrated; can be mechanically connected, or can be electrically connected; can be directly connected, or can be indirectly connected through an intermediate medium, or can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0025] In the present application, unless explicitly defined and limited otherwise, the first feature “on” or “under” the second feature can include that the first and second features are in direct contact, or can include that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, the first feature “on”, “above” and “on” the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature.

[0026] As Figs. 1-4As shown, the embodiment provides a kind of organic solid waste fast pyrolysis device with pre-treatment system, including: crusher 1, screening assembly 2, dryer 3, conveying assembly 4 and pyrolysis machine 5;The crusher 1 is formed with crushing cavity, shear assembly is arranged in the crushing cavity, the screening assembly 2 is inclinedly arranged at the outlet of the crushing cavity, the baffle 7 is arranged in parallel below the screening assembly 2, the material channel 8 is formed between the screening assembly 2 and the baffle 7, the conveying assembly 4 is arranged at the bottom end of the material channel 8, for conveying material, the dryer 3 and the pyrolysis machine 5 are sequentially arranged on the conveying assembly 4;

[0027] The shear assembly includes first shaft 101, a plurality of first rotary blades 102, second shaft 103 and a plurality of second rotary blades 104, the first shaft 101 and the second shaft 103 are arranged in parallel, a plurality of the first rotary blades 102 are arranged on the first shaft 101, a plurality of the second rotary blades 104 are arranged on the second shaft 103, there is a gap between adjacent two first rotary blades 102, and the second rotary blade 104 is arranged corresponding to the gap.

[0028] Based on the above scheme, the organic solid waste first enters the crushing cavity, and the shear assembly on the first shaft 101 and the second shaft 103 cooperates. The two shafts rotate relatively, the first rotary blade 102 and the second rotary blade 104 form shear force in the staggered gap, cut and tear the large block material, and ensure that the material crushing granularity is uniform. The crushed material is screened by the inclined screening assembly 2, the qualified particle size material passes through the screen hole 201 and falls into the material channel 8 below;Unqualified coarse particles are recycled and treated again under the action of gravity along the inclined surface of the screening assembly 2, realizing dynamic screening. The channel formed by the baffle 7 and the screening assembly 2 directionally guides the material, avoiding blockage. The conveying assembly 4 conveys the screened material to the dryer 3, reduces the moisture content by hot air or indirect heating, and then conveys to the pyrolysis machine 5. The dried material is rapidly pyrolyzed in the pyrolysis machine 5, because the particle size after pre-treatment is uniform and the moisture content is low, the heat transfer efficiency of pyrolysis reaction is high, and the product quality is stable.

[0029] Overall, the double-shaft staggered shearing assembly is adopted to realize strong shearing through the gap fit of the rotating blade, which significantly improves the crushing efficiency; combined with dynamic screening and return mechanism, it ensures uniform particle size of the material and avoids the problem of uneven pyrolysis heat transfer, coking and efficiency decline caused by large pieces of material. The dryer 3 is integrated in the conveying path, which directly dries the screened material, reduces the moisture content, shortens the pyrolysis time and reduces the side reactions, and improves the yield and purity of the products (such as bio-oil, combustible gas). The pretreatment system (crushing, screening, drying) and the pyrolysis machine 5 are seamlessly connected through the conveying assembly 4, which simplifies the process flow, reduces the energy consumption and equipment area of material transfer, and overcomes the complexity defects caused by traditional independent pretreatment unit. The inclined arrangement of the screening assembly 2 and the directional channel formed by the baffle 7, combined with the continuous transmission of the conveying assembly 4, avoid material accumulation and blockage, and ensure the continuous and stable operation of the system.

[0030] Further, the shearing assembly further comprises a driving assembly 105, a power end of the driving assembly 105 is connected with the first rotating shaft 101, the driving assembly 105 comprises a driving motor 1051, a driving wheel 1052, a transmission belt 1053 and a driven wheel 1054, an output shaft of the driving motor 1051 is connected with the driving wheel 1052, the driven wheel 1054 is connected with the driving wheel 1052 through the transmission belt 1053, the first rotating shaft 101 is connected with the driven wheel 1054, an end of the first rotating shaft 101 away from the driven wheel 1054 is provided with a transmission assembly 106, the second rotating shaft 103 is connected with the first rotating shaft 101 through the transmission assembly 106, so that the first rotating shaft 101 and the second rotating shaft 103 rotate synchronously.

[0031] In this scheme, the driving motor 1051 serves as the power source, and its output shaft is connected to the driving wheel 1052. When the driving motor 1051 starts, the driving wheel 1052 rotates accordingly. The driving wheel 1052 drives the driven wheel 1054 to rotate through the transmission belt 1053, and the driven wheel 1054 is connected to the first rotating shaft 101, thereby driving the first rotating shaft 101 to rotate. The first rotating shaft 101 is provided with a transmission assembly 106 at the end away from the driven wheel 1054, and the second rotating shaft 103 is connected to the first rotating shaft 101 through the transmission assembly 106, realizing the synchronous rotation of the first rotating shaft 101 and the second rotating shaft 103. This design ensures that the shearing blades on the two rotating shafts can rotate at the same speed and direction, forming an effective shearing force, cutting and tearing the organic solid waste entering the crushing cavity, and ensuring uniform particle size of the crushed material. The driving assembly 105 realizes stable and reliable power transmission through the cooperation of the motor, the driving wheel 1052, the transmission belt 1053 and the driven wheel 1054, ensuring that the shearing assembly can work continuously and efficiently, and improving the operation stability of the whole device. By adjusting the rotating speed of the driving motor 1051, the rotating speed of the first rotating shaft 101 and the second rotating shaft 103 can be accurately controlled, so as to adjust the shearing force and shearing frequency of the shearing blades, adapt to the crushing needs of different materials, and improve the crushing efficiency and effect. The design of the transmission assembly 106 enables the first rotating shaft 101 and the second rotating shaft 103 to rotate synchronously, ensuring that the shearing blades on the two rotating shafts maintain consistent shearing effect during rotation, avoiding uneven shearing caused by different rotating speeds, and further improving the uniformity of material crushing. The structure of the driving assembly 105 is relatively simple, and each component is assembled through standard mechanical connection method, which is convenient for daily maintenance and fault elimination. For example, the replacement of the transmission belt 1053 is relatively easy, reducing maintenance cost and downtime. By reasonably designing the transmission ratio and motor power of the driving assembly 105, energy can be used efficiently while meeting the shearing requirements, reducing energy consumption and improving the energy utilization efficiency of the whole device.

[0032] In some embodiments, the screening assembly 2 comprises a vibrating screen provided with a plurality of screen holes 201 arranged in an array, the screen holes 201 having a pore size of 3-10 mm. The vibrating screen achieves the screening of the material by high-frequency vibration, which makes the material constantly jump on the screen holes 201. The specific process is as follows: after the material enters the vibrating screen, due to the high-frequency vibration of the screen holes 201, small-particle materials fall into the material channel 8 below through the screen holes 201, while large-particle materials move along the surface of the screen holes 201 and are eventually collected and returned to the crushing cavity for further processing. The array arrangement of the screen holes 201 ensures the uniformity and efficiency of the screening process. The high-frequency vibration of the vibrating screen can effectively improve the screening efficiency, ensuring that the material completes the screening in a short time and is suitable for large-scale production. The screen holes 201 have a pore size of 3-10 mm, which can accurately control the particle size of the material and ensure the uniformity of the particle size of the material entering the subsequent processing link, improving the heat transfer efficiency of the pyrolysis reaction and the product quality. The vibrating screen is suitable for the screening of various materials, including organic solid waste of different shapes and humidity, and has wide applicability.

[0033] Preferably, a recovery box 6 is provided above the bottom end of the material channel 8, which is used to recover the material that does not pass through the screening assembly 2. When the material passes through the screening assembly 2, the material with qualified particle size falls into the material channel 8 below through the screen holes 201 and continues to be transported and processed subsequently. The material that does not pass through the screening assembly 2, i.e. the material with larger particle size, will slide along the inclined surface of the screening assembly 2 and fall into the recovery box 6. The recovery box 6 collects these materials that do not pass the screening for subsequent reprocessing or return to the crushing cavity for secondary crushing, ensuring that all materials can meet the required particle size requirements. If the material that does not pass the screening is not recovered, it may scatter in the surrounding environment, causing environmental pollution. The provision of the recovery box 6 can effectively prevent this from happening and keep the working environment clean.

[0034] It is worth mentioning that the dryer 3 is a hot air machine, the hot air temperature of which is set to 80-120℃, the wind speed is 2-5m / s, and the drying time is 10-30 minutes. After the material passes through the screening assembly 2, it is sent to the dryer 3 by the conveying assembly 4. The hot air temperature generated by the hot air machine is set between 80-120℃, the wind speed is 2-5m / s, and the drying time is 10-30 minutes. The hot air uniformly blows to the material through the air duct of the dryer 3, so that the moisture on the surface of the material evaporates rapidly, thereby reducing the moisture content of the material. The dried material continues to be sent to the pyrolysis machine 5 by the conveying assembly 4 for subsequent processing. The high-temperature and high-speed hot air generated by the hot air machine can quickly remove the moisture in the material, the drying time is short, the efficiency is high, and it is suitable for large-scale production. The hot air temperature and wind speed of the hot air machine can be adjusted according to the characteristics of the material and the drying requirements, to ensure the consistency and stability of the drying effect. By reasonably setting the hot air temperature and wind speed, and optimizing the drying time, the drying effect can be ensured while reducing energy consumption, achieving the goal of energy saving and high efficiency. The moisture content of the dried material is low, which can quickly reach the temperature required for pyrolysis reaction after entering the pyrolysis machine 5, shortening the pyrolysis time and improving the pyrolysis efficiency.

[0035] In particular, a sealing dustproof plate is arranged between the dryer 3 and the conveying assembly 4, which mainly prevents dust generated during drying from overflowing and keeps the working environment clean. The specific working process is as follows: after the material is dried by hot air in the dryer 3, it is sent to the pyrolysis machine 5 by the conveying assembly 4. The sealing dustproof plate is installed at the connection between the dryer 3 and the conveying assembly 4, forming a closed channel to ensure that the dried material does not leak dust during transportation. The sealing dustproof plate is usually made of flexible material, which can adapt to slight vibration and thermal expansion of the equipment to ensure sealing effect.

[0036] The beneficial effects include: preventing dust from overflowing: the sealing dustproof plate can effectively prevent dust generated during drying from overflowing, protect the cleanliness of the working environment, and reduce the health hazards to the operators.

[0037] Improve the sealing of the equipment: by setting the sealing dustproof plate, the sealing between the dryer 3 and the conveying assembly 4 is improved, ensuring that the material will not be affected by the external environment during transportation, and maintaining the consistency of the drying effect.

[0038] Reduce maintenance cost: the setting of the sealing dustproof plate reduces the pollution of the equipment by dust, reduces the maintenance cost and downtime of the equipment, and prolongs the service life of the equipment.

[0039] Improve production efficiency: by preventing dust from overflowing, the equipment failure and downtime caused by dust leakage are reduced, and the efficiency of the entire production process is improved.

[0040] In line with environmental requirements: the setting of the dustproof sealing plate helps to reduce dust emission, in line with environmental requirements, and improve the social responsibility and image of the enterprise.

[0041] Optionally, the pyrolysis machine 5 comprises a pyrolysis reactor, and a stirring assembly is arranged in the pyrolysis reactor. The stirring assembly generally comprises a stirring shaft and stirring paddles, the stirring shaft is fixed in the pyrolysis reactor through a support structure, and the stirring paddles are installed on the stirring shaft. The function of the stirring assembly is to stir the material during the pyrolysis process, so that the material is in full contact with the pyrolysis gas in the pyrolysis reactor, and the pyrolysis reaction is promoted. The specific working process is as follows: after the material enters the pyrolysis reactor, the stirring assembly rotates under the driving of the driving device, the stirring paddles uniformly turn and mix the material, ensuring that the material is evenly heated in the pyrolysis reactor, improving the pyrolysis efficiency and product quality. The stirring assembly can make the material uniformly distributed in the pyrolysis reactor, avoid local overheating or uneven heating, and improve the efficiency and uniformity of the pyrolysis reaction. Through stirring, the material is in full contact with the pyrolysis gas, promoting the pyrolysis reaction and improving the yield and quality of the pyrolysis products. The stirring assembly can prevent the material from caking or adhering to the inner wall of the pyrolysis reactor during the pyrolysis process, keeping the pyrolysis reactor clean and normal operation. Uniform stirring can ensure that the material is evenly heated during the pyrolysis process, improving the quality and stability of the pyrolysis products. By preventing material caking and adhesion, the stirring assembly helps to reduce the wear and corrosion of the pyrolysis reactor, prolonging the service life of the equipment.
